Description

The invention relates to a, in particular contactless, actuating device for a vehicle, preferably for an access system of the vehicle, for actuating, preferably unlocking and/or opening, a, in particular handleless, movable part, such as a door or hatch, of the vehicle. Furthermore, the invention relates to a corresponding access system for a vehicle with a corresponding actuating device.

Actuating devices in the form of door handles (on doors or hatches) for access devices in vehicles are generally known. Known actuating devices often have sensor devices within the door handle, which serve to automatically actuate moving parts, such as a door or a hatch (especially the tailgate), in vehicles. Known sensor devices usually have sensors that can monitor the vehicle's surroundings in order to detect a user. Radar sensors are increasingly being used as sensors in vehicles. Modern vehicles are increasingly being equipped with aerodynamically adapted moving parts, which are designed, if possible, without (additional) gaps, joints and/or recesses, e.g. for handles. However, the operation of such access devices does not always prove to be safe, particularly with regard to obstacle control in the movement area of the moving part, which can open automatically.

It is therefore also a disadvantage if such operating devices in the form of door handles always protrude from the moving part or the vehicle in order to be visible and/or accessible to the user of the vehicle.

The object of the invention is therefore to at least partially overcome the disadvantages described above. In particular, the object of the invention is to provide an improved, in particular contactless, actuating device for a vehicle, in particular for an access system of the vehicle, for actuating, preferably unlocking and/or opening, a movable part of the vehicle, in particular a handle-free part, wherein the aerodynamics of the vehicle are advantageously unaffected by the actuating device while driving. Preferably, the object of the invention is to provide an actuating device, in particular contactless, for a vehicle, in particular for an access system of the vehicle, for actuating, preferably unlocking and/or opening, a movable part of the vehicle, in particular a handle-free part, which is safe and reliable in operation and which enables safe actuation of the movable part, preferably with regard to obstacle control in the movement range of the movable part, which are actuated automatically. Furthermore, the object of the present invention is to provide a corresponding access system for a vehicle with a corresponding actuating device.

This object is achieved by a, in particular contactless, actuating device for a vehicle, in particular for an access system of the vehicle, for actuating, preferably unlocking and/or opening, a, in particular handleless, movable part of the vehicle with the features of the independent device claim and by a corresponding access system for a vehicle with a corresponding actuating device according to the independent system claim. Preferred developments of the actuating device are listed in the dependent claims. Features disclosed for the individual embodiments of the actuating device according to the invention and the access system according to the invention can be combined with one another in such a way that reciprocal reference is or can always be made to the embodiments with regard to the disclosure.

The invention provides a, in particular contactless, actuating device for a vehicle, preferably for an access system of the vehicle, for (preferably automatically) actuating (at least comprising unlocking and/or opening) a, in particular handleless, movable part of the vehicle. The movable part is preferably designed in the form of a door, e.g., a side door, a sliding door, or a flap, e.g., a tailgate, fuel tank or loading flap, or a hood, of the vehicle. Typically, several movable parts are provided on the vehicle, in particular to be able to close the interior of the vehicle, which can be locked and/or unlocked and, if necessary, opened and/or closed by the access system.

• - ein Flügelelement mit einem Gehäuse, wobei das Flügelelement dazu ausgeführt ist, an dem beweglichen Teil des Fahrzeuges angeordnet zu sein,
• - eine Sensorvorrichtung, welche dazu ausgeführt ist, mindestens einen Betätigungsbereich (vorzugsweise mindestens zwei) beim Fahrzeug zu überwachen, wobei die Sensorvorrichtung zumindest teilweise oder vollständig im Gehäuse des Flügelelements untergebracht ist, und
• - eine Elektronikvorrichtung, welche insbesondere dazu ausgeführt ist, die Sensorvorrichtung derart anzusteuern, um eine Detektion eines Benutzers in dem mindestens einen Betätigungsbereich (und insbesondere eine Detektion eines Hindernisses in einem Bewegungsbereich des beweglichen Teils) durchzuführen,

wobei das Gehäuse des Flügelelements derart ausgeführt ist, dass die (äußere) Form des Gehäuses zumindest zwischen einer Ruheform und einer Funktionsform veränderbar ist.The actuating device according to claim 1 comprises:

• - a wing element with a housing, wherein the wing element is designed to be arranged on the movable part of the vehicle,
• - a sensor device designed to monitor at least one actuation area (preferably at least two) on the vehicle, wherein the sensor device is at least partially or completely housed in the housing of the wing element, and
• - an electronic device which is particularly designed to control the sensor device in such a way as to detect a user in the at least one actuation area (and in particular to detect an obstacle in a movement area of the movable part),

wherein the housing of the wing element is designed such that the (external) shape of the housing can be changed at least between a rest shape and a functional shape.

In other words, the external shape (design) of the housing of the wing element can adapt to a particular situation (of the actuating device or the vehicle) and has at least one resting shape and a different functional shape. This makes it possible to adapt the respective shape of the wing element to the different requirements and conditions (of the actuating device or the vehicle) (depending on the situation). Especially in cases of space constraints, since the installation space for the actuating device is generally limited, adapting the shape of the housing (e.g., to a resting position of the actuating device and at least one operating position of the actuating device) represents a major technical advantage.

The wing element can, for example, be arranged hidden behind and/or recessed into the movable part (e.g., rest position) and/or adjacent to the movable part. It is also conceivable for the wing element to be arranged protruding from the movable part (e.g., operating position).

Advantageously, the shape of the wing element can be aerodynamically adapted (as well as adjustable or adaptable) to the shape of the movable part, preferably to maintain the aerodynamic properties of the movable part and/or to limit or even reduce the air resistance on the movable part during operation of the vehicle. Furthermore, it is conceivable that the wing element can be designed in a wing-like, fin-like, and/or rudder-like manner. The sensor device, in particular, is arranged on or within the wing element (or the corresponding housing).

The sensor device itself can preferably monitor the at least one actuation area using electromagnetic waves, in particular radar waves. The sensor device has at least one or more sensor elements, which can be configured differently (in particular due to their physical measuring principle). The actuation area of a sensor element is also referred to below as the detection area, whereby the actuation areas can be composed at least partially or entirely of the detection areas of the sensor elements of the sensor device. Furthermore, at least one capacitive sensor element (or several) can at least partially monitor its detection area or a predetermined detection area in a contactless manner, in particular in order to metrologically detect a user approaching the vehicle or a preferably contactless actuation action by a user in front of the actuation device. This can, for example, initiate a data exchange with a user-side device, in particular in the form of an ID transmitter or mobile phone or the like, for example for authentication on the access system.

The electronic device (which can also be arranged within the housing of the wing element) can in particular be designed to control the sensor device in such a way as to detect, in particular by radar detection (in particular in the 79 GHz range), an obstacle (interfering object) in the area of the movable part in order to reliably avoid a collision during an automatic opening process of the movable part. The electronic device can also be suitable for controlling the sensor device in such a way as to recognize (and optionally evaluate) at least one user or a user action and/or to communicate with a user-side device, e.g. in the form of a mobile phone or an ID transmitter. This allows an access system, in particular in the form of a central locking system, to be controlled and preferably unlocked or locked, and optionally also opened or closed.

Actuating the movable part (by the actuating device) can be understood as unlocking and/or opening the movable part as well as closing and/or locking the movable part. In order to hold the movable part in the closed position on the vehicle, an electromechanical lock is preferably provided, which can be controlled (directly or indirectly) by the actuating device. In the closed position, the movable part is mechanically fixed to the vehicle by the lock. As soon as the lock no longer closes the movable part, it can be opened, whereby the lock can also at least assist the opening process of the movable part. In addition, a (door) drive can also be provided to move the movable part in order to assist the opening and/or closing process. Moving or the movement of the movable part can mean opening and/or closing the movable part. part (between at least 2 positions).

Furthermore, the actuating device can also be designed to close and/or lock the movable part, wherein, in particular, the actuating device can act in a contactless or contact-based manner for closing the movable part, wherein, preferably, the actuating device can act in a contact-based manner for locking the movable part. The actuating device can preferably generate at least one or more control signals for the aforementioned unlocking and/or locking processes as well as opening and/or closing, in particular based on the measurement data from the sensor device and, if applicable, their evaluation. In other words, the actuating device can serve primarily to actuate the movable part, in particular by a user (in particular comparable to a door handle).

It is further provided that the wing element is designed to be movably arranged on the movable part of the vehicle, and that the sensor device is fixedly arranged on the wing element. The term “movable” in this context should be understood to mean that the wing element is movably arranged (for (preferably contactless) actuation by a user) on the movable part and can therefore assume at least two different positions, namely at least one rest position and one operating position on the movable part. Due to the mobility of the wing element, the actuation range of the fixed sensor device or its fixed sensor elements can be adjusted and/or changed, so that the overall actuation range (as well as the detection range of the individual sensor element and/or the sensor device) can be increased. Advantageously, this also makes it possible to reduce the number of sensor elements required to detect a defined actuation range. The aerodynamic design of the actuation device can also be adapted to the respective vehicle situation, e.g. motorway driving with the wing element retracted (rest position) in the movable part or e.g. B. Parking situation with extended wing element (operating position) on the movable part in order to operate it shortly.

In this way (movable wing element), it can be made possible for an enlarged actuation range to be detected by the sensor device, which in particular avoids blind zones in the movement range of the movable part and/or substantially encloses the movement range of the movable part.

In this way, the actuating device can also provide obstacle control during the movement, preferably opening, of a movable part, particularly a handleless one. This can be described as a so-called impact protection function of the actuating device, i.e., it prevents the movable part from colliding with an obstacle during the opening process (e.g., through (capacitive and/or radar) monitoring of the corresponding detection area), since the obstacle has been measured in advance by the corresponding sensor element.

However, the actuating device can also provide obstacle control during the movement, preferably closing, of a movable part, particularly one without handles. This can be referred to as a so-called pinch protection function of the actuating device.

Furthermore, it is conceivable for the wing element to have a rest position and at least one (or more) operating positions, wherein in the rest position the wing element assumes its rest shape and can be arranged hidden behind and/or in the movable part and/or leaning flat against the movable part, and wherein in the at least one operating position the wing element assumes its functional shape and can be arranged on the movable part in such a way that the sensor device can detect the at least one actuation area. In this way, an unobtrusive and/or aerodynamically favorable mounting of the wing element in the rest position and rest shape can be enabled. At the same time, in the at least one operating position and the functional shape of the wing element, an enlarged actuation area can be provided by the sensor device, which in particular avoids blind zones and/or essentially completely encloses the (geometric/actual) range of movement of the movable part.

By changing (or adapting) the shape of the wing element (between the resting shape and the functional shape) to the respective resting or operating position, the space required for the actuating device within or in the area of the movable part can be significantly optimized, particularly in the resting position. Thus, by adapting the shape of the wing element (in the resting position), a geometric adaptation to the existing height and/or width and/or depth of the installation space can also be achieved. In at least one operating position, the wing element in its functional shape can assume its optimal shape and design for monitoring the existing detection areas by the (integrated) sensor elements.

Furthermore, the wing element can have a first operating position and a second operating position (wherein the wing element assumes its functional shape at least in one position), wherein in the first operating position the wing element can be arranged on the movable part such that the sensor device can detect a first actuation range, and wherein in the second operating position the wing element can be arranged on the movable part such that the sensor device can detect a second actuation range. In this way, even with a sensor device fixedly arranged on the wing element, an enlarged actuation range can be provided by the sensor device.

Advantageously, the housing of the wing element can be designed in multiple parts, with at least two or more housing parts being present. The existing housing parts (of the housing of the wing element) can also be designed to be movable relative to one another by means of at least one adjustment mechanism or adjustment area, in particular in the form of a joint or a hinge or a (linear or curved) guide, whereby the overall shape of the housing can be changed. This allows for a space-specific adaptation of the wing element or the actuating device (to the movable part or vehicle).

It is also conceivable for the at least two or more housing parts of the housing of the wing element to be designed so that they can move relative to one another, such that at least two adjacent (directly next to one another / directly connected) housing parts can be rotated, pivoted, folded, folded or retracted relative to one another, at least in part (or completely). For example, the housing of the wing element can be folded together or apart like a folding rule. The housing of the wing element can also be designed, for example, like a rod or telescopic antenna that can be pushed in and out. Furthermore, the individual housing parts that can move relative to one another can create an accordion-like structure for the housing of the wing element, which is designed to be extremely flexible and adaptable.

It is also possible within the scope of the invention for the housing of the wing element to be designed to be at least partially or completely flexible, in particular by means of an elastic material, in so-called flex areas or a complete flex area. This makes it possible to change the shape of the housing as a whole. The elastic material for the flexible areas (flex areas) can preferably comprise at least one elastomer. In this case, an (additional) adjustment mechanism for moving two housing parts relative to one another is not absolutely necessary, but can nevertheless be present. Consequently, the housing can be designed similarly to a rubber rod, whereby the rubber rod can also be curved rather than just straight.

In order to adapt the shape of the housing of the wing element between the rest shape and the functional shape, this can be changed by at least one or more adjusting elements, wherein the adjusting elements can be controlled electromechanically (preferably by the electronic device), whereby mechanical forces can be exerted by the adjusting elements on the housing or on individual housing parts. In this case, at least one adjusting element can preferably have at least one rod-shaped, wire-like, or chain-like element, or a combination thereof, in order to transmit the required adjusting forces or torques to the housing or its housing parts. Also preferably, at least one adjusting element can have at least one shape memory alloy (SMA) in order to effect the adjustability of the housing.

Combinations between the listed housings (the wing elements) and the connection between the respective housing parts are also conceivable. For example, the upper part of the housing can be formed by telescopic housing parts that slide into one another, while the lower part of the housing is connected to the upper part of the housing via an adjustment mechanism or a flexible section.

Furthermore, it can be provided that in the flexible areas and/or at the connection points between the at least two or more housing parts of the housing, the electronic components (meaning all electrical components, such as sensor elements, electronic, lighting, and communication devices, etc. within the housing) are electrically connected to one another via flexible printed circuit boards and/or flexible ribbon cables and/or cables. By directly electrically contacting the respective electronic components in one housing part with another (movable and adjacent) housing part, a complex electrical structure of the wing element and the connection of the electronic components to one another can be avoided.

Preferably, the intermediate areas between the housing parts of the housing of the wing element are sealed to each other by sealing elements and/or by the material of the flexible areas themselves in order to prevent water and/or dirt from entering this area. It is also conceivable that the entire housing is provided with a flexible casing to ensure reliable sealing. Ideally, the housing is sealed in both the resting and functional states, but at least in the functional state.

Advantageously, the wing element can be movable such that, during the movement of the wing element, the at least one actuation region is continuously formed by the sensor device, so that an enlarged actuation region is dynamically created, which in particular avoids blind zones and/or substantially encloses the movement range of the movable part. The sensor device can perform a detection during the movement of the wing element. Thus, an enlarged actuation region I, II can be dynamically provided.

Advantageously, the wing element can be arranged on the movable part and/or designed to be fluidically adapted to the aerodynamic properties of the movable part in such a way that the aerodynamic properties of the movable part are maintained and/or the air resistance on the movable part is limited during vehicle operation. This allows advantageous use of the actuating device even with a fixed wing element.

Advantageously, the electronic device can be designed to control the sensor device in such a way that not only a detection of a user in the at least one actuation area, but also a detection of an obstacle (e.g. an object such as a side mirror of a nearby parked vehicle, a post, a tree, etc., or a person or a body part of a person) in the movement area of the movable part can be carried out.

Thus, an improved, in particular contactless, actuating device for a vehicle, in particular for an access system of the vehicle, for actuating, preferably unlocking and/or opening, a, in particular handleless, movable part of the vehicle can be provided, which is safe and reliable in operation and which enables safe actuation of the movable part, preferably with regard to obstacle control in the movement range of the movable part, which are actuated automatically.

Furthermore, the wing element can be designed to be arranged on a movable part in the form of a door, e.g., a side door, sliding door, or a hatch, e.g., a tailgate, of the vehicle. In this way, the actuating device can enable obstacle control when actuating, preferably unlocking and/or opening, a door or hatch of the vehicle.

Furthermore, the wing element can be designed to be arranged between the movable part, in particular in the form of a movable door or flap, and a movable window or a body element of the vehicle. In this way, the actuating device can be arranged at existing joints and/or gaps between the components of the vehicle, so that the movable part can be designed without (additional) gaps, joints and/or recesses, e.g. for handles. In this way, advantageous flow-related and/or aerodynamic properties can be ensured for the movable part. With the aid of the actuating device, the advantageous functions of a contactless actuating device can be provided within the framework of a handle-free access system, preferably in the form of a keyless-go or keyless entry system, even without a handle on the movable part, which is automatically actuated, in particular automatically moved.

Advantageously, the wing element can be designed for an operative connection with an electromechanical lock (for the movable part). The lock can be designed to actuate the movable part of the vehicle, in particular to unlock and/or open and/or close and/or lock it. The lock can, for example, form part of a corresponding access system. Actuation of the movable part can thus be enabled via the wing element. At least one actuation action (at least approach, touch and/or movement pattern and/or gesture) of the user can preferably be detected on the wing element using the sensor device. One actuation action can be determined for each corresponding actuation (such as unlocking and subsequent opening) of the movable part.

Preferably, the electronic device can be configured to generate a corresponding control signal for the lock in order to control the lock in accordance with an actuation action of the user detected by the sensor device. Authentication, preferably of a user using a user-side device, can also take place, as described in more detail below.

In addition, it is conceivable that at least one sensor element, in particular a radar sensor element, of the sensor device has a first actuation action (approach, touch and/or movement pattern and/or gesture) of the user. The radar sensor element can locate (determine distance and angle) a measured object and/or a user in the detection area. The radar sensor element is preferably operated at a frequency (in the range) of 79 GHz or using UWB technology (ultra-wideband technology). The first actuation can trigger unlocking and/or opening of the movable part, for example by generating a corresponding control signal for the lock via the electronic device.

Furthermore, it is conceivable that at least one sensor element, in particular a radar sensor element, of the sensor device can detect a second actuation (approach, touch, and/or movement pattern) of the user. The second actuation can initiate closing and/or locking of the movable part, for example by the electronic device generating a corresponding control signal for the lock. For closing the movable part, the second actuation can be, for example, a movement pattern or a gesture on at least one sensor element. For locking the movable part, the second actuation can be, for example, a touch of at least one sensor element of the sensor device.

Furthermore, the wing element can be designed to be moved linearly along the movable part of the vehicle. This allows for simple mounting and/or stable guidance of the wing element, allowing an increased operating range for the sensor device. This allows the wing element to be arranged at existing joints and/or gaps between the vehicle components, allowing the movable part to be designed without (additional) gaps, joints, and/or recesses, e.g., for handles.

Furthermore, the wing element can be designed to be rotatably and/or tiltably mounted on the movable part of the vehicle. This allows for simple mounting and/or advantageous guidance of the wing element, thus enabling an enlarged operating range for the sensor device. The wing element can also be arranged at existing joints and/or gaps between the vehicle components.

A combination of linear and rotatable and/or tiltable movement of the wing element is also conceivable. As provided by the invention, the housing of the wing element can also be adapted between a resting position and a functional position.

Advantageously, a mounting bracket can be provided for the wing element to hold and/or support the wing element on the moving part of the vehicle. The mounting bracket can preferably be arranged on the inside of the moving part. This allows a complete structural unit for the actuating device to be provided to enable simple installation on the vehicle. The mounting bracket can be designed as a housing or frame to improve mechanical stability. With a housing-like design, unlike a frame-like design, the other components (e.g., bearing device, drive device, gear, wing element in the rest position, etc.) of the actuating device can also be protected from dirt and moisture.

Furthermore, a bearing device for the wing element can be provided, in particular on a mounting bracket, in order to movably support and/or guide the wing element on the movable part of the vehicle. The bearing device can advantageously enable the wing element to be captively mounted on the vehicle and to perform a desired movement, such as a linear and/or rotatable and/or tilting movement.

Furthermore, a drive device for the wing element can be provided, in particular on a mounting bracket, to movably drive the wing element on the movable part of the vehicle. Using the drive device, a desired movement, such as a linear and/or rotatable and/or tilting movement, of the wing element can be generated. The drive device can also additionally serve to adapt the shape of the wing element. It is also conceivable to have multiple drive devices to fulfill different purposes.

In principle, it is conceivable that the sensor device can have a first sensor element and a second sensor element, wherein the first sensor element of the sensor device can be designed to detect a first actuation area, and wherein the second sensor element of the sensor device can be designed to detect a second actuation area. Thus, an enlarged actuation area can be formed in a simple manner by the sensor elements of the sensor device, which preferably avoids blind zones and/or Essentially includes the entire range of movement of the movable part. In addition, this enables advantageous functionality in the actuating device. In this way, the sensor device can be used to detect at least one or more movement patterns, wherein in particular one movement pattern can be provided for a specific actuating action. An approach and/or a first movement pattern can, for example, serve to unlock and/or open the movable part. A distance and/or a second movement pattern can, for example, serve to close the movable part. Touching a specific sensor element can, for example, serve to lock the movable part.

Furthermore, it is conceivable for the sensor device to have a first sensor element and a second sensor element, which are aligned such that an enlarged actuation area is detected by the sensor device. In this way, an enlarged actuation area can be formed.

According to a particular advantage, the electronic device can be designed to control the sensor device, in particular at least one sensor element of the sensor device, to detect an obstacle in the movement range of the movable part, in particular by means of detection, preferably radar detection. In particular, the electronic device can be designed to provide a warning signal and/or a stop signal when the sensor device detects an obstacle in the movement range of the movable part.

In this way, obstacle control can be provided during the movement, preferably opening, of a movable part, particularly one without handles. Thus, a so-called impact protection function can be provided as a function of the actuating device.

In this way, obstacle control can be provided during the movement, preferably closing, of a movable part, particularly a handleless one. Thus, a so-called pinch protection function can be provided as a function of the actuating device.

Thus, the electronic device can control the sensor device in such a way that not only a detection of a user in the at least one actuation area, but also a detection of an obstacle (e.g. an object such as a side mirror of a nearby parked vehicle, a post, a tree, etc., or a person or a body part of a person) in the movement area of the movable part (both outwards and inwards with respect to the vehicle) can be carried out.

Thus, when operating the moving part of the vehicle, especially the handleless part, the safety in the area of movement of the moving part can be increased.

Furthermore, it may be advantageous for the electronic device to be configured to control the sensor device, in particular at least one sensor element of the sensor device, to perform an authorization query, in particular by means of communication with a user-side device, preferably a mobile phone, ID transmitter, etc., in order to enable, in particular, user authentication. In this way, it can be ensured that only an authorized user can initiate the actuation, in particular the unlocking and/or opening of the movable part of the vehicle, in particular the handleless part.

Furthermore, it may be advantageous for the electronic device to be designed to control the sensor device, in particular at least one sensor element of the sensor device, to detect an approach, a contact and/or a specific movement pattern, in particular with the aid of detection, preferably radar detection, in order to initiate unlocking and/or opening of the movable part after detection. Furthermore, it is conceivable for at least one sensor element, in particular a radar sensor element, of the sensor device to be able to detect a first actuation (approach, contact and/or movement pattern) of the user. The first actuation can trigger unlocking and/or opening of the movable part. For this purpose, the electronic device can generate a corresponding control signal for the lock.

Furthermore, it may be advantageous for the electronic device to be designed to control the sensor device, in particular at least one sensor element of the sensor device, to detect an approach, a contact, and/or a specific movement pattern, in particular with the aid of detection, preferably radar detection, in order to initiate a closing and/or locking of the movable part after detection. Furthermore, it is conceivable that at least one sensor element, in particular a radar sensor element, of the sensor device can detect a second actuation action (approach, contact, and/or movement pattern) of the user. The second actuation action Closing and/or locking of the movable part can be initiated. For this purpose, the electronic device can generate a corresponding control signal for the lock. For closing the movable part, the second actuation action can be, for example, a movement pattern on at least one sensor element. For locking the movable part, the second actuation action can be, for example, a touch of at least one sensor element of the sensor device.

Advantageously, the sensor device can comprise at least one radar sensor element, one UWB sensor element, in particular comprising a pulse radar or continuous wave radar measuring method, one capacitive sensor element, one inductive sensor element, one piezo sensor element, and/or one NFC sensor element. A radar sensor element or a UWB sensor element can advantageously enable detection (e.g., for detecting an approach, a touch, and/or a movement pattern) and communication (e.g., for performing an authorization query). A capacitive sensor element can advantageously enable detection (e.g., for detecting an approach, a touch, and/or a movement pattern). An inductive sensor element or a piezo sensor element can enable detection (e.g., for detecting a touch). An NFC sensor element can enable communication (e.g., for performing an authorization query). But detection (e.g. to detect an approach into close range to the wing element or a touch) is also conceivable using an NFC sensor element.

In order to enable convenient movement of the movable part by the user and/or emergency release of the movable part by the rescue services in the event of an accident, the wing element can be designed as a handle element (with an emergency release mechanism), in particular one that can be extended (and/or rotated out and/or swung out).

In order to enable an extended functionality of the actuating device, the actuating device can be designed to carry out a locking, an unlocking and/or an emergency release of the movable part.

In addition, at least one sensor element of the sensor device can be designed to carry out a locking, for example by means of a touch of this sensor element.

Furthermore, at least one sensor element of the sensor device can be configured to perform an unlocking action, for example, by approaching the wing element into an expanded access area. An authorization query can then be initiated. The same and/or another sensor element of the sensor device can further sense an approach, a touch, and/or a movement pattern to trigger the opening of the movable part.

Particularly with regard to safety, especially in the event of a vehicle accident, the actuating device can offer further advantages if the wing element (or an additional emergency release element on the actuating device) has an emergency release mechanism that can be coupled to the electromechanical lock of the movable part (at least in the event of an accident). For this purpose, the emergency release mechanism has a coupling element and at least a first and/or second tension element. The existing tension elements can be designed at least partially as a cable, wire, rod and/or a chain. Preferably, the coupling element mechanically couples the first tension element to the second tension element (exclusively) during and/or directly after an accident, so that a pulling movement from the first tension element can be mechanically transmitted to the second tension element. For this purpose, the first tension element is preferably mechanically arranged (connected) between the actuating device, in particular the wing element or the additional emergency release element, and the coupling element, and the second tension element is preferably mechanically arranged (connected) between the coupling element and the electromechanical lock. During or immediately after an accident, a coupling is established by the coupling element, so that an emergency release, for example, by a mechanical pulling movement on the actuating device, in particular the wing element or the additional emergency release element, is transmitted to the electromechanical lock in order to ultimately open the movable part. The (electrical) control of the coupling element for coupling can be carried out by an acceleration sensor or crash sensor, e.g., via the electronic device or the control device. The wing element (or an additional emergency release element on the actuating device) can advantageously serve as a tangible handle element of the emergency release to enable manual opening of the movable part, e.g., by rescue workers who require access to the vehicle interior. In the event of an accident, automatic unlocking of the moving part may also be provided.

Furthermore, the actuating device can have a lighting device designed to make the actuating device visible for actuation. Advantageously, the lighting device can be designed for ambient lighting of the wing element. According to a further advantage, the lighting device can be designed for interaction with a user, preferably to facilitate actuation of the actuating device and preferably to guide the user during actuation of the actuating device.

To enable expanded functionality of the actuating device, the actuating device may further comprise a communication device configured to enable interaction with a user, preferably to facilitate the actuation of the actuating device and preferably to guide the user in the actuation of the actuating device. The communication device may comprise an optical, acoustic, and/or haptic display device.

The invention provides an access system for a vehicle, comprising a, in particular contactless, actuating device, which can be designed as described above.

Within the scope of the access system, a control device can be provided which is designed to stop the actuation, in particular the opening, of the movable part when the sensor device detects an obstacle in the movement range of the movable part, in particular by means of detection, preferably radar detection, and/or when the electronic device provides a warning signal.

In the following figures, the same reference numerals are used for the same technical features, even in different embodiments.

The figures show a, in particular contactless, actuating device 100 with a wing element 10 for a vehicle 200, preferably for an access system 110 of the vehicle 200, for, preferably automatically, actuating a, in particular handleless, movable part 201 of the vehicle 200. As the 1 and 2 To illustrate, the movable part 201 can be designed, for example, in the form of a door, e.g. a side door, or a flap, e.g. a tailgate, of the vehicle 200.

Actuation of the movable part 201 by a user 300 (with a user-side Device for identification) may comprise unlocking and/or opening the movable part 201 and/or closing and/or locking the movable part 201 of the movable part 201.

Moving the movable part 201 may include opening and/or closing the movable part 201.

On the one hand, the actuating device 100 can be designed to unlock and/or open the movable part 201, wherein in particular the actuating device 100 can act without contact to unlock and/or open the movable part 201.

On the other hand, the actuating device 100 can also be designed to close and/or lock the movable part 201, wherein in particular for closing the movable part 201 the actuating device 100 can act in a contactless or contact-based manner, wherein preferably for locking the movable part 201 the actuating device 100 can act in a contact-based manner.

• - ein Flügelelement 10 mit einem Gehäuse 10.1, welches dazu ausgeführt ist, an dem beweglichen Teil 201 des Fahrzeuges 200 angeordnet zu werden,
• - eine Sensorvorrichtung 20 (vgl. 3), welche dazu ausgeführt ist, mindestens einen Betätigungsbereich I, II beim Fahrzeug 200 zu überwachen (vgl. 1 bis 3), wobei die Sensorvorrichtung (20) zumindest teilweise oder vollständig im Gehäuse (10.1) des Flügelelements (10) untergebracht ist, und
• - eine Elektronikvorrichtung 30, welche insbesondere dazu ausgeführt ist, die Sensorvorrichtung 20 derart anzusteuern, um eine Detektion eines Benutzers in dem mindestens einen Betätigungsbereich I, II (vgl. 2), und vorzugsweise eine Detektion eines Hindernisses in einem Bewegungsbereich des beweglichen Teils 201, durchzuführen,

wobei das Gehäuse 10.1 des Flügelelements 10 derart ausgeführt ist, dass die Form des Gehäuses 10.1 zumindest zwischen einer Ruheform RF und einer Funktionsform FF veränderbar ist.As the figures illustrate, the actuating device 100 comprises the following components:

• - a wing element 10 with a housing 10.1, which is designed to be arranged on the movable part 201 of the vehicle 200,
• - a sensor device 20 (cf. 3 ), which is designed to monitor at least one actuation area I, II in the vehicle 200 (cf. 1 to 3 ), wherein the sensor device (20) is at least partially or completely accommodated in the housing (10.1) of the wing element (10), and
• - an electronic device 30, which is designed in particular to control the sensor device 20 in such a way as to detect a user in the at least one actuation area I, II (cf. 2 ), and preferably to detect an obstacle in a movement range of the movable part 201,

wherein the housing 10.1 of the wing element 10 is designed such that the shape of the housing 10.1 can be changed at least between a rest shape RF and a functional shape FF.

In principle, it is conceivable that the wing element 10 can be arranged, at least in a rest position P0, hidden behind and/or recessed in the movable part 201 (cf. 4a , 5a , 6a) . Here, the housing 10.1 of the wing element 10 is generally arranged in its rest form RF.

Furthermore, it is conceivable that the wing element 10 can be leaned against the movable part 201 at least in an operating position P2 from the outside with respect to the vehicle 200 (cf. illustration of the wing element 10, see 4b , 5b , 6b and 8 ).

Furthermore, it is conceivable that the wing element 10 can be arranged protrudingly on the movable part in the functional form FF at least in one operating position P1, P2 (cf. 7 and 8 ).

As shown in the figures, the shape of the wing element 10 can be aerodynamically adapted to the shape of the movable part 201 in order to preferably maintain the aerodynamic properties of the movable part 201 and/or to keep the air resistance on the movable part 201 low during operation of the vehicle 200.

The wing element 10 can be designed in a wing-like, fin-like and/or rudder-like manner.

The sensor device 20 can monitor the at least one actuation area I, II preferably by means of electromagnetic waves, in particular radar waves.

The electronic device 30 can preferably be designed to control the sensor device 20 in such a way as to carry out a detection, in particular a radar detection, of a user 300 and/or a communication with a user-side device 301, for example in the form of a mobile phone or an ID transmitter.

As the 4 to 11 As indicated, the wing element 10 can be arranged in a movable and shape-changing manner on the movable part 201 of the vehicle 200. At the same time, the sensor device 20 is arranged fixedly on the wing element 10.

By means of the proposed actuating device 100, an enlarged actuating area I, II can be detected by the sensor device 20, as described in 1 to 3 The enlarged actuation range I, II includes almost no blind zones in the movement range of the movable part 201 and/or covers the movement range of the movable part 201 almost completely.

In the 3 The enlarged operating area I, II is indicated by means of opening angles. The enlarged operating area I, II comprises at least a first operating area area I and at least one second actuation area II of the sensor device 20. It can be seen that an obstacle 206, which is indicated next to a tire 205 of the vehicle 200, can be detected in the enlarged actuation area I, II, in particular in the second actuation area II.

The actuation area I, II can also be referred to in other words as a detection area.

In this way, the actuating device 100 can provide obstacle control when moving, preferably opening, a movable part 201, in particular a handleless one (so-called shock protection as a function).

Furthermore, it is also conceivable that the actuating device 100 can provide obstacle control during the movement, preferably closing, of a movable part 201, in particular a handleless one (so-called pinch protection as a function of the actuating device 100).

Thus, the sensor device 20 can not only detect a user 300 in the at least one actuation area I, II, but also detect an obstacle 206, for example an object such as a side mirror of a nearby parked vehicle, a post, a tree, etc., or a person or a body part of a person, in the movement range of the movable part 201.

Thus, an improved, in particular contactless, actuating device 100 for actuating a, in particular handleless, movable part 201 of the vehicle 200 can be provided, which is safe and reliable in operation and which enables safe actuation of the movable part 201, preferably with regard to obstacle control in the movement range of the movable part 201 when the movable part 201 is automatically moved (opened or closed).

With the aid of the actuating device 100, the advantageous functions of a contactless actuating device can be provided within the framework of a handleless access system 110, preferably in the form of a keyless-go or keyless entry system.

As the 1 to 3 As indicated, the wing element 10 can be arranged on a movable part 201 in the form of a door, e.g., a side door, or a flap, e.g., a tailgate, of the vehicle 200. In this way, the actuating device 100 can be used to provide obstacle control when actuating, in particular opening and/or closing, a door or flap of the vehicle 200.

Furthermore, it is conceivable that the wing element 10 can be arranged between the movable part 201, in particular in the form of a movable door or flap, and a movable window 202 or a body element 203 of the vehicle 200 (not shown in the figures merely for reasons of simplicity).

Advantageously, the actuating device 100 can be arranged at existing joints and/or gaps between the components of the vehicle 200, so that the movable part 201 can be designed without (additional) gaps, joints, and/or recesses, e.g., for handles. Thus, the movable part 201 can be advantageously configured to achieve favorable flow and/or aerodynamic properties.

As the 1 and 2 indicate, the wing element 10 can be brought into operative connection with an electromechanical lock 204 in order to control the lock 204 accordingly.

The lock 204 can be designed to actuate the movable part 201 of the vehicle 200, in particular to unlock and/or open and/or close and/or lock it. The lock 204 can, for example, form part of a corresponding access system 110.

The wing element 10 thus enables actuation of the movable part 201. At the wing element 10, at least one actuation action B1, B2, such as an approach, touch, and/or a movement pattern, of the user 300 can preferably be detected using the sensor device 20. One actuation action B1, B2 can be determined for a corresponding actuation of the movable part 201.

Preferably, the electronic device 30 can be designed to generate a corresponding control signal for the lock 204 in order to control the lock 204 in accordance with an actuation action B1, B2 that was detected by the sensor device 20 on the wing element 10.

The sensor device 20 may have at least one sensor element 21, 22, 23, in particular a radar sensor element.

At least one sensor element 21, 22, 23, in particular radar sensor element, the sensor element The device 20 can detect a first actuation B1, such as an approach, touch, and/or a movement pattern, of the user 300. The first actuation B1 can be provided, for example, for unlocking and/or opening the movable part 201.

At least one sensor element 21, 22, 23, in particular a radar sensor element, of the sensor device 20 can detect a second actuation B2, such as an approach, touch, and/or a movement pattern, of the user 300. The second actuation B2 can be provided, for example, for closing and/or locking the movable part 201.

To close the movable part 201, the second actuation action B2 can, for example, provide a movement pattern which can be detected, for example, by means of two sensors 21, 22.

To lock the movable part 201, the second actuating action B2 may, for example, provide for contact with a specific sensor element 23 of the sensor device 20.

As indicated, the wing element 10 can be mounted and/or guided in a linearly movable manner on the movable part 201 of the vehicle 200. This can enable simple mounting and/or stable guidance of the wing element 10, for example, between a rest position P0 and rest shape RF and at least one operating position P1, P2 and functional shape of the wing element 10. A movable arrangement and the shape adaptation of the wing element 10 can provide an enlarged actuation range I, II by the sensor device 20.

As further at least partially indicated, the wing element 10 can be rotatably and/or tiltably mounted and/or guided on the movable part 201 of the vehicle 200. This can also enable simple mounting and/or advantageous guidance of the wing element 10, in particular between a rest position P0 and at least one operating position P1, P2, in order to provide an enlarged actuation range I, II by the sensor device 20.

A combination of a linear and a rotatable and/or tiltable movement of the wing element 10 with respect to the movable part (201) is also conceivable.

As the 3 ff. indicate, a mounting bracket 11 for the wing element 10 can be provided in order to support the wing element 10 on the movable part 201 of the vehicle 200. The mounting bracket 11 can, for example, be arranged on the inside of the movable part 201.

As the 3 ff. further indicate, a bearing device 12 for the wing element 10, in particular on a mounting support 11, can be provided in order to movably support and/or guide the wing element 10 on the movable part 201 of the vehicle 200.

As the 3 ff. further indicate, a drive device 13 for the wing element 10, in particular on a mounting support 11, can be provided in order to drive the wing element 10 movably on the movable part 201 of the vehicle 200.

As is the case in the 4 to 6 As shown, the wing element 10 can have a rest position P0 as well as a rest shape RF ( 4a , 5a , 6a) and at least one operating position P1, P2 and one functional form ( 4b , 5b , 6b) In the rest position P0 / rest form RF, the wing element 10 can be arranged hidden behind and/or recessed in the movable part 201 and/or leaning flat against the movable part 201 in order to ensure inconspicuous and/or aerodynamically favorable mounting of the wing element 10. In the at least one operating position P1, P2 / functional form FF, the wing element 10 can be arranged on the movable part 201 in such a way that the sensor device 20 can detect the at least one actuation area I, II, in particular an enlarged actuation area I, II, preferably comprising a second actuation area II, in order to avoid blind zones and/or to cover the movement area of the movable part 201 as completely as possible.

Furthermore, the wing element 10 can have a first operating position P1 and a second operating position P2 with the functional form FF (only for reasons of simplicity not shown in the 4b , 5b , 6b) . In the first operating position P1, the wing element 10 can be arranged on the movable part 201 such that the sensor device 20 can detect a first actuation area I. In the second operating position P2, the wing element 10 can be arranged on the movable part 201 such that the sensor device 20 can detect a second actuation area II. By means of the first actuation area I and the second actuation area II, an enlarged actuation area I, II can be provided by the sensor device 20 with the aid of the movable wing element 10.

Advantageously, the wing element 10 can be moved in such a way that during the movement of the wing element 10 the at least one actuation The sensor device 20 continuously forms the detection area I, II, so that an enlarged actuation area I, II is dynamically created, which in particular avoids blind zones and/or essentially encloses the movement range of the movable part 201. The sensor device 20 can continuously perform detection during the movement of the wing element 10. Thus, an enlarged actuation area I, II can be dynamically provided.

In the 4a ,b the wing element 10 is adjustable in its shape so that it can be folded like a folding rule (or articulated chain) between the functional form FF and the rest form RF. How well in the 4a As can be seen, the total height of the wing element 10 is significantly reduced by the housing parts 10.1.a,b,c of the housing 10 in the rest form RF compared to the height of the wing element 10 in the functional form FF from the 4b This allows the necessary installation space for the wing element 10 in the movable part 201 to be significantly reduced.

The housing parts 10.1.a, b form two adjacent housing parts 10.1, just like the two housing parts 10.1.b, c., since they are directly connected to each other.

In the functional form FF from 4b The entire housing 10 of the wing element 10 has a longitudinal extension due to the folding or extending of the housing parts 10.1.a, b, c. To enable movement of the housing parts 10.1.a, b, c relative to one another, at least one adjustment mechanism 10.2, in the form of a pivot joint or a hinge, is provided. Ideally, the adjustment area is sealed off by the existing adjustment mechanisms 10.2 so that no water or dirt can penetrate there. In this extended functional form FF, optimal detection of the detection area I, II can take place by the sensor device 20 with the respective sensor elements 21, 22, 23 (etc.).

In the 5a ,b the shape of the wing element 10 is adjustable in such a way that it can be flexibly moved or pivoted between the functional form FF and the rest form RF, similar to a rubber rod (or an accordion). The housing 10 has so-called flexible areas 10.3.a,b made of elastic material between the respectively connected housing parts 10.1.a,b,c. The advantage of this design is, among other things, that no further sealing elements are required in the area of the flexible areas 10.3.a,b and yet a very good seal is already provided in this area. Also, no adjustment mechanism is required between the adjacent housing parts 10.1.a,b,c.

The two forms RF and FF shown from the 5a ,b are only exemplary embodiments of the possible shapes of the housing 10.1 of the wing element 10 in the various positions P0,1,2. The rest shape RF of the wing element 10 is expediently adapted to the available installation space in the movable part 201.

Advantageously, the housing parts 10.1.a,b,c can be separated from the housing 10.1 from the 4 and 5 may differ in length, width, cross-section and cross-sectional shape, which further increases the adaptability of the wing element.

Both 6a ,b, the wing element 10 is designed to be telescopically (antenna-like) retractable by the shape-changing housing 10.1. Unlike the 4 and 5 The housing parts 10.1.a, b, and c necessarily each have a different cross-section in size (but not in external cross-sectional shape) in order to be able to be guided or slid into one another. Thus, the length or height of the wing element 10 (in the rest form RF and functional form FF) can be adapted to the available installation space in a very simple manner.

Furthermore, it can generally be provided that in the flexible areas 10.3.a,b and/or at the connection points 10.2 between the at least two or more housing parts 10.1.a,b,c of the housing 10, the electronic component parts (meaning all electrical components, such as sensor elements, electronic, lighting and communication devices, etc. within the housing) are electrically connected to one another via flexible printed circuit boards 19 and/or flexible ribbon cable 19 and/or cable 19, as in the 6b is indicated by dash points.

As the 9 to 11 show, the drive device 13 may have a gear 14 to transmit a drive action for driving to the wing element 10.

As the 9 As shown, the gear 14 may comprise a worm gear. A worm gear may be rotatably mounted on the mounting bracket 11 and interact with the vane element 10 to move the vane element 10, in particular linearly.

As the 10 shows, the gear 14 can have a pivoting gear. A pivoting lever can be rotatably mounted on the mounting bracket 11 and can cooperate with the wing element 10. to move the wing element 10, in particular rotatably.

As the 11 As shown, the gear 14 can comprise a pulley gear. A roller can be rotatably mounted on the mounting bracket 11 and interact with the wing element 10 via a cable to move the wing element 10, in particular linearly.

In principle, it is conceivable that a combination of a guide slot in a bearing device 12 and a gear 14 in a drive device 13 can enable a combined, in particular linear and/or rotatable and/or tiltable, movement of the wing element 10.

As the 11 shows, a return mechanism 15, in particular a return spring, for the wing element 10 can be provided on the mounting support 11 in order to transfer the wing element 10 from at least one operating position P1, P2 ( 7 ) into a rest position P0 ( 6 ) to enable.

In principle, it is conceivable that the sensor device 20 can have a first sensor element 21 and a second sensor element 22. The first sensor element 21 of the sensor device 20 can be designed to detect a first actuation area I. The second sensor element 22 of the sensor device 20 can be designed to detect a second actuation area II. Thus, an enlarged actuation area I, II can be formed with the aid of sensor elements 21, 22 of the sensor device 20. Furthermore, advantageous functionality in the actuation device 100 can be enabled with the aid of sensor elements 21, 22 of the sensor device 20. In this way, the sensor device 20 can serve to detect at least one or more movement patterns. In particular, a movement pattern can be provided for each specific actuation action B1, B2.

An approach and/or a first movement pattern can serve, for example, to unlock and/or open the movable part 201. A distance and/or a second movement pattern can serve, for example, to close the movable part 201. Touching a specific sensor element 23 of the sensor device 20 can serve, for example, to lock the movable part 201.

Advantageously, the electronic device 30 can be specifically designed to control the sensor device 20 to detect an obstacle in the movement range of the movable part 201, in particular by means of detection, preferably radar detection. Furthermore, the electronic device 30 can be designed to provide a warning signal and/or a stop signal when the sensor device 20 detects an obstacle in the movement range of the movable part 201. Thus, improved obstacle detection can be provided by means of the electronic device 30.

Furthermore, the electronic device 30 can be specifically designed to control the sensor device 20 to perform an authorization query, in particular by means of communication with a user-side device 301, preferably a mobile phone, ID transmitter, etc. In this way, authentication of the user 300 can be ensured, so that only an authorized user can initiate the actuation, in particular the unlocking and/or opening of the movable part 201 of the vehicle 200, in particular the handleless one.

Furthermore, the electronic device 30 can be specifically designed to control the sensor device 20 to detect an approach, a contact and/or a specific movement pattern, in particular by means of detection, preferably radar detection, in order to initiate unlocking and/or opening of the movable part 201 after detection.

Furthermore, the electronic device 30 can be designed to control the sensor device 20 to detect an approach, a contact and/or a specific movement pattern, in particular by means of detection, preferably radar detection, in order to initiate a closing and/or locking of the movable part 201 after detection.

The electronic device 30 can generate corresponding control signals for the lock 204 according to a specific actuation action of the user 300.

Advantageously, the sensor device 20 can comprise at least one radar sensor element or one UWB sensor element, in particular operated according to a pulse radar or continuous wave radar measurement method. A radar sensor element or a UWB sensor element can advantageously enable detection, e.g., for detecting an approach, a touch, and/or a movement pattern, as well as communication, e.g., for performing an authorization query.

Advantageously, the sensor device 20 may comprise at least one capacitive sensor element, an inductive sensor element, a piezo sensor element, and/or an NFC sensor element. A capacitive sensor element can advantageously enable detection, e.g., to detect an approach, a touch, and/or a movement pattern. An inductive sensor element or a piezo sensor element can enable detection, e.g., to detect a touch. An NFC sensor element can enable communication, e.g., to perform an authorization query. However, an NFC sensor element can also enable detection, e.g., to detect an approach into close proximity to the wing element or a touch.

In principle, it is conceivable that the wing element 10 can be designed as a handle element, in particular one that can be extended and/or rotated and/or pivoted out. This allows convenient movement of the movable part 201 by the user 300 during normal operation and/or by the rescue services in the event of an accident involving the vehicle 200.

Furthermore, it is conceivable that the actuating device 100 can be designed to carry out an emergency release of the movable part 201.

For this purpose, the wing element 10 (or an additional emergency release element on the actuating device 100) can have an emergency release mechanism 18 (see schematically in the 7 and 8 ), which can be mechanically coupled to the electromechanical lock 204 of the movable part 201, at least in the event of an accident, preferably by at least the first or second coupling element 17.1, 17.2, preferably automatically by the coupling element 16. During or directly after an accident, a coupling is established by the coupling element 16, so that an emergency release, for example by a mechanical pulling movement on the actuating device 100, in particular the wing element 10 or the additional emergency release element, is transmitted to the electromechanical lock 204 in order to finally open the movable part 201. The wing element 10 or an additional emergency release element can advantageously serve as a tangible handle element to enable manual opening of the movable part 201 by the rescue services.

In the event of an accident, an access system 110 for a vehicle 200 may be provided for automatic unlocking of the movable part 201.

As the 3 ff., the actuating device 100 can have a lighting device 40. The lighting device 40 can be designed to make the actuating device 100 visible for actuation. The lighting device 40 can be designed, for example, for ambient lighting of the wing element 10. Furthermore, the lighting device 40 can be designed for interaction with a user 300 in order to guide the user 300 in actuating the actuating device 100.

Furthermore, the actuating device 100 can have a communication device 50 designed to enable interaction with a user 300 in order to guide the user 300 in actuating the actuating device 100. The communication device 50 can, for example, have an optical, acoustic, and/or haptic display device.

An access system 110 for a vehicle 200, comprising a, in particular contactless, actuating device 100, which can be designed as described above, also represents an aspect of the invention.

Within the scope of the access system 110, a control device 120 may be provided, which is designed to stop the actuation, in particular the opening, of the movable part 201 when the sensor device 20 detects an obstacle in the movement range of the movable part 201, in particular by means of detection, preferably radar detection, and/or when the electronic device 30 provides a warning signal. In this way, obstacle control, including impact and/or pinch protection, can be ensured.

The access system 110 can comprise an electromechanical lock 204, which can be controlled, in particular, by means of a control device 120, to actuate the movable part 201, in particular to unlock and/or open it, as well as to close and/or lock it. The control device 120 can receive corresponding control signals from the electronic device 30, which are generated according to specific actuation actions B1, B2 of the user 300, which are detected by the sensor device 20.

The above explanation of the embodiments describes the present invention exclusively within the scope of examples. Of course, individual features of the present invention can be freely combined with one another, provided that they are technically feasible, without departing from the scope of the present invention/claims.
