The invention provides a touch panel.

In an embodiment of the present invention, the touch panel includes:

connecting shaft 500;

Two fixing parts 200, the two fixing parts 200 are respectively fixedly connected to the two ends of the connecting shaft 500, the fixing parts 200 are provided with a plurality of limiting grooves 220 distributed at intervals in the circumferential direction, two The limiting groove 220 of the fixing member 200 opens toward each other; and

Two support plates 300, the support plate 300 is provided with a sleeve portion 310, the sleeve portion 310 is sleeved outside the connecting shaft 500, the sleeve portion 310 of the two support plates 300 is in the The connecting shaft 500 is distributed in the axial direction, and a limiting protrusion 320 protrudes oppositely in the axial direction, and the supporting plate 300 can move axially relative to the connecting shaft 500 to have a first position and a second position; In the first position, the limiting convex part 320 selects one of the limiting grooves 220 to engage, so as to limit the circumferential rotation of the support plate 300 relative to the connecting shaft 500; in the second position, The limiting protrusion 320 disengages from the limiting groove 220 , and the supporting plate 300 can rotate circumferentially relative to the connecting shaft 500 .

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the connecting shaft 500 is connected with two opposite fixed parts 200, and the connection mode is a fixed connection, respectively located at the two ends of the connecting shaft 500, so that the connecting shaft 500 There is a space on the shaft body for the connection of the support plate 300, and the space is located between the two opposite fixed parts 200. Two support plates 300 are installed in the space where the support plate 300 is installed on the connecting shaft 500. The connection mode between the support plate 300 and the connecting shaft 500 is a flexible connection. It can rotate around the axis of the connecting shaft 500 and move along the axial direction of the connecting shaft 500 . In this embodiment, the movable connection is realized by providing the socket portion 310 connected with the connecting shaft 500 on the support plate 300 , and the distribution direction of the socket portion 310 of the two support plates 300 is consistent with the axis of the connecting shaft 500 to the same. The fixing member 200 in the technical solution of the present invention is provided with a plurality of limiting grooves 220 (circumferential direction). A limiting protrusion 320 is provided on the supporting member, wherein the limiting grooves 220 of the two fixing members 200 on the connecting shaft 500 are arranged facing each other, and the limiting protrusions 320 on the two supporting plates 300 on the connecting shaft 500 are arranged opposite to each other. , and the limit groove 220 can limit the position of the limit protrusion 320 in the axial direction of the connecting shaft 500, because the limit groove 220 is provided in the circumferential direction of the connecting shaft 500, so the fixing member 200 can limit the position of the support plate 300 in the axial direction of the connecting shaft 500. Circumferential rotation of the connecting shaft 500 .

In this technical solution, when the support plate 300 is in the first position, the limit groove 220 is snapped into by the limit protrusion 320 and restricts the movement of the limit protrusion 320, when the support plate 300 is in the second position, When the limiting protrusion 320 is out of the limit of the limiting groove 220, it is in the second position. It can be understood that the position limiting protrusion 320 can switch between the first position and the second position through the movement of the support member in the axial direction of the connecting shaft 500 , and when the position limiting protrusion 320 breaks away from the limit of the position limiting groove 220 In the second position, the support member can rotate around the connecting shaft 500, so that the relative positions of the two support members will continuously change with their respective rotational movements, until the limiting protrusion 320 of the support member snaps into the fixing member 200 again One of the limiting grooves 220 realizes the fixing of the relative position. Since there are multiple limiting grooves 220 in the fixing part 200, there are also multiple relative positions of the two supporting parts on the connecting shaft 500. The included angle between the two supporting boards 300 is adjusted so that the touchpad in the second state can fit the user's hand, thereby facilitating the user's operation. Wherein, no matter in the first state or the second state of the touchpad, the support board 300 can sense the touch operation of the user, so that the user can perform corresponding operations on the notebook computer through the touchpad.

It can be understood that the adjustment process of the shape of the touchpad is as follows: firstly, before the shape of the touchpad is adjusted, the support plate 300 is always at the first position, and the user needs to pull out the limiting protrusion 320 of the support plate 300 first. Corresponding to the limiting groove 220 , this step realizes the transformation of the support plate 300 from the first position to the second position, and also makes the support plate 300 free from the restriction of the fixing member 200 and can rotate around the connecting shaft 500 . When the support plate 300 belongs to the second position, the user adjusts the support plate 300 to a suitable position, and then inserts the limiting convex part 320 in the supporting plate 300 into the limiting groove 220 of the fixing part 200 to realize the support The transition of the pad 300 from the second position to the first position, in turn, adjusts the shape of the touchpad.

Therefore, in the technical solution of the present invention, in the first state of the touch panel, the touch panel is installed on the device main body 800, and the two support plates 300 are relatively flattened, that is, used as a traditional touch panel for the user Perform a simple click operation. If the user needs to perform more complicated operations, the touchpad can be removed from the device main body 800, and the shape of the touchpad can be adjusted so that the angle between the two support plates 300 fits the user's hand, thereby By switching the touchpad to the second state, the touchpad can also be used as a mouse for the user to operate.

Further, a touch panel 100 is provided on the same side of the two support plates 300, and one of the touch panels 100 is provided with at least one pressure sensor, and in the first state, the pressure sensor is electrically connected to the main body of the device The main control board of 800, in the second state, the pressure sensor is communicatively connected to the main control board. It can be understood that the touch panels 100 are disposed on the same side of the two support plates 300 , that is, all the touch panels 100 are located on one side of the touch panel. In this embodiment, at least one pressure sensor is provided on the touch panel 100 so that one side of the touch panel has the function of identifying external information. Of course, in other embodiments, a capacitive sensor can be used to identify external information. That is, the bracket between the electrodes of the capacitive sensor is a structure that deforms as the pressure changes, and the deformation of the structure leads to a change in capacitance, so that information can be identified based on the change in capacitance.

The technical solution divides the state of the touchpad into a first state and a second state. The first state is the state when the touchpad is installed on the notebook computer, and the second state is the state when the touchpad is separated from the notebook computer. When the touch panel is in the first state, the pressure sensor is electrically connected to the main control board of the device body 800, that is, the pressure sensor and the device body 800 transmit information through conductive connection. This connection method simplifies the connection steps and procedures. The assembly efficiency is improved to a certain extent. This technical solution also stipulates that when the touch panel is in the second state, the pressure sensor is connected to the main control panel by communication, that is, the information is transmitted through a wireless connection. The board is not restricted by the position of the main body 800 of the device, which better improves the user experience. It can be understood that the operation logic of the touchpad in the second state is different from the operation logic in the first state, but similar to the operation logic of the mouse, that is, not all of the two touch panels in the touchpad are operable , one of which plays a supporting role, and the other plays an operating role. Although the supporting touch panel can also identify information, the main control board does not have information feedback, and the operating touch panel has two sensing areas distributed in the left and right directions, and the main control board is sensitive to the left and right sides. The information processing and information feedback of the sensing area are different. The left sensing area is consistent with the left button information processing and information feedback of the mouse, and the right sensing area is consistent with the right mouse button information processing and information feedback. Furthermore, for the convenience of the user's operation, a separation line can be set on the touch panel which functions as an operation, so that the user can distinguish the sensing areas on the left and right sides.

Further, an installation cavity is formed in each of the support plates 300, and a battery is accommodated and installed in the installation cavity, and the pressure sensor is fixedly connected to the touch panel 100 and electrically connected in the corresponding installation cavity. For the battery, in the first state, the battery is electrically connected to the main control board. It can be understood that the establishment of the battery in the installation cavity can enable the touch panel to have power to maintain the functions of communication and receiving information when it is in the second state. In the first state, the battery is electrically connected to the main control board to charge the battery for use in the second state, which meets the battery life requirement and improves user efficiency.

Further, the support plate 300 is provided with an exposed conductive part, which is used to contact and conduct with the conductive interface exposed outside the device main body 800 in the first state, and the conductive interface is electrically connected to the main control board , the battery is electrically connected to the conductive part. It can be understood that when the support plate 300 is in the first state, that is, when the support plate 300 is installed on the device main body 800 , the conductive portion communicates with the conductive interface. The connection between the exposed conductive part and the conductive interface provides a circuit channel for the battery and the main control board, which realizes the charging requirement of the battery, does not require too many charging electronic components, and saves charging costs. Of course, in other embodiments, the battery can also be charged through wireless charging.

Further, the touch panel further includes an indicator light exposed on the touch panel 100 , the indicator light is electrically connected to the battery, and is used to indicate the power of the battery. It can be understood that the indicator light exposed on the surface of the touch panel 100 can intuitively reflect the power of the battery in the touch panel, and then the user can decide how to use the touch panel according to the amount of power, and charge it in time when the power is low. Improved user experience and efficiency.

Further, in the first state, adjacent sides of the touch panel 100 of the two support plates 300 are spliced together. It can be understood that the touch panel 100 is provided on the same side of the two support plates 300, and this technical solution stipulates that the adjacent sides of the touch panel 100 are spliced, so that the touch panel 100 becomes an integral touch panel, eliminating the need for two support plates. The gaps between the corresponding touch panels further protect electronic components such as sensors inside the touch panels from being damaged by dust, and also play a role in beautifying the appearance.

Further, the touch panel also includes a scroll wheel 600. In the first state, the sensor of the scroll wheel 600 is electrically connected to the main control panel of the device body 800. In the second state, the scroll wheel The sensor of 600 is communicatively connected to the main control board; the roller 600 is located between the two socket parts 310, and is rotatably sleeved on the connecting shaft 500, and is connected to the connecting shaft 500 in the axial direction. The shaft 500 is relatively fixed, and in the second state, the scroll wheel 600 is protruding from the touch panel 100 . It can be understood that, on the connecting shaft 500, a roller 600 is provided between the socket parts 310 of the two support plates 300, and the roller 600 can rotate around the connecting shaft 500. The unique scroll wheel 600 sensor enables the main control board to recognize and process the rotation of the scroll wheel 600 accordingly, which improves the user's convenience and operation diversity. In this embodiment, the movement of the roller 600 in the axial direction is limited by setting limit structures on both sides of the roller 600 in the axial direction, so that the roller 600 can only rotate, and the situation that the sensor of the roller 600 misidentifies the roller 600 is avoided. It should be noted that when the touchpad is in the first state, the scroll wheel 600 should be accommodated inside the touchpad; when the touchpad is in the second state, the scroll wheel 600 should be protruding from the touch panel 100 so that the user The scroll wheel 600 can be directly touched, so that instructions can be sent to the main control board through the scroll wheel 600 . In this embodiment, the touch panel 100 is provided with an escape groove 400. When the touch panel is in the first state, the scroll wheel 600 is accommodated in the avoidance groove 400. When the touch panel is in the second state, the scroll wheel 600 moves out of the escape groove. The notch in 400 protrudes from the touch panel 100 . The touchpad in this embodiment also includes a dustproof cover made of elastic material. When the touchpad is in the first state, the dustproof cover is engaged with the avoidance groove 400. Since the avoidance groove 400 of the touchpad communicates with the interior of the touchpad and the External, so there is the possibility of external dust entering the inside of the touchpad, and the setting of the dust cover prevents dust from entering the inside of the touchpad. Since the dust cover is made of elastic material, when the two support plates 300 rotate relative to each other, the dust cover can be easily pulled out from the escape groove 400 without damaging the structure of the touch panel.

Further, the connecting shaft 500 is provided with a mounting ring protrusion on both axial sides of the roller 600, and the touch panel also includes two return springs 700, and the two return springs 700 are installed on the two sides. The opposite side of the ring protrusion is sleeved on the connecting shaft 500, and the two ends of each return spring 700 are respectively connected to the corresponding installation ring protrusion and the sleeve part 310, and the return spring 700 Under the action of , the support plate 300 has a tendency to maintain at the first position. It can be understood that, in this embodiment, the limiting mechanisms on both sides of the axial direction of the roller 600 are installation ring protrusions, which restrict the axial movement of the roller 600 on the connecting shaft 500, so that the position of the roller 600 in the axial direction is fixed constant. A return spring 700 is provided on the convex side of the installation ring facing the support plate 300 , and the other end of the return spring 700 is connected to the sleeve portion 310 of the support plate 300 . It can be understood that no matter whether the support plate 300 is in the second position or the first position, the return spring 700 is always in a compressed state, which will always generate a thrust to the bottom of the limit groove 220 on the support plate 300, so that the support plate 300 The limiting convex portion 320 is more stably pressed in the limiting groove 220, thereby increasing the stability of the support plate 300, thereby making the touch panel difficult to disassemble when being used by the user, and improving the user experience. Of course, in other embodiments, the same effect can also be achieved by the magnetic force generated by the magnetic attraction between the limiting groove 220 and the limiting protrusion 320 .

Further, opposite ends of the two fixing pieces 200 are provided with guide ring grooves 210, and the limiting grooves 220 are recessed in the guide ring grooves 210. At the second position, the limiting protrusions 320 It is slidably inserted into the guide ring groove 210 . The setting of the guide groove will impose a circumferential restriction on the position-limiting protrusion 320 in the second position, so that the position-limiting protrusion 320 will move along the groove wall of the guide groove in the circumferential direction of the connecting shaft 500; Upward, only the first position and the second position can be switched, which reduces the possibility of other sliding of the limiting protrusion 320 at the second position, thereby improving the position of the limiting protrusion 320 between the first position and the second position. The speed of switching between them saves the user's switching time, improves efficiency, and improves the user experience.
