The present invention provides a sensor mounting structure 10.
The sensor mounting structure 10 provided by the utility model can be applied to mobile equipment needing obstacle avoidance through a sensor, such as a sweeping robot, an intelligently movable air purifier, a humidifier, an air conditioner and the like. Specifically, during walking, the mobile device usually needs to sense a static or dynamic obstacle existing on a planned route thereof through a sensor, and then update the route in real time according to a certain algorithm to bypass the obstacle, or temporarily stop traveling until the obstacle leaves the planned route, continue traveling, and finally move to a target point.
Sensors used for obstacle avoidance on mobile equipment are generally infrared sensors, laser sensors, ultrasonic sensors, vision sensors and the like, different sensor types have different advantages and disadvantages, and selection can be performed according to the working requirements of the mobile equipment in actual design. Regardless of the type of sensor, the sensing principle of the surrounding obstacle is basically related to the position relationship between the sensor itself and the obstacle, such as the distance relationship, the orientation relationship, the size relationship, and the like between the sensor and the obstacle. Therefore, the positional accuracy when the sensor is mounted on the mobile device is particularly important, otherwise it is easy for the mobile device 70 to hit an obstacle due to a sensing deviation. However, in some existing mobile devices, it is difficult to ensure the position accuracy of the sensor during installation due to the influence of installation process, size, fixing manner, and other factors. The sensor mounting structure 10 of the present invention is proposed to improve the positional accuracy of the sensor at the time of mounting.
Specifically, in the embodiment of the present invention, as shown in fig. 2 to 6, the sensor mounting structure 10 includes a mounting panel 20, a mounting case 30, and a sensor 40. The mounting panel 20 of the present invention refers to a structure or a part of a structure such as a housing, a decorative plate, a bezel, or a cover plate, to which the sensor 40 is connected when the sensor 40 is assembled to the mobile device 70, and may be referred to as the mounting panel 20 of the present invention.
As shown in fig. 1, for example, a mobile device 70 is taken as a mobile humidifier, which includes a mobile chassis 71 and a function module 72 mounted on the mobile chassis 71. The movable chassis 71 mainly comprises a disk body, rollers rotatably mounted on the disk body, and a driving motor for driving the rollers to roll, wherein the driving motor drives the rollers to roll to drive the movable chassis 71 to move, and then the movable chassis 71 drives the functional module 72 to move.
The functional module 72 mainly includes a hollow housing, a centrifugal fan installed in the housing, a humidifying component installed at an air inlet of the centrifugal fan, an air guide grille 73 installed at an air outlet of the centrifugal fan, and the like. Wherein, the shell is the enclosed type or partly encloses the enclosed type panel structure to mainly used holding and protection centrifugal fan, humidification part etc. the position that corresponds the centrifugal fan air intake on this shell is provided with ventilation mesh 74, and the upper end of shell is the opening setting and is used for supplying air guide grid 73 to install. The inner surface of the housing is provided with the sensor 40, the control panel and other components, so that the housing is the mounting panel 20 of the present invention, or the part of the housing where the sensor 40 is mounted is the mounting panel 20 of the present invention.
Generally, the sensor 40 is generally installed on a panel in the forward direction of the mobile device 70, and of course, in the case that the mobile device 70 travels via a universal wheel and needs to go forward, go backward or turn at any time, the sensor 40 needs to be installed on the installation panel 20 in different directions of the mobile device 70 according to actual conditions to ensure that the mobile device 70 can smoothly move to the destination according to the preset route.
In the present embodiment, as shown in fig. 4, the mounting panel 20 is provided with a first positioning groove 21, and the bottom of the first positioning groove 21 is provided with a first signal window 22. Specifically, the mounting panel 20 in the present embodiment has a substantially semi-enclosed panel structure, and includes a first panel surface and a second panel surface that are opposite to each other, and a third panel surface connected between the first panel surface and the second panel surface. The first plate surface and the second plate surface are respectively arranged opposite to the air inlet of the centrifugal fan and are respectively provided with a ventilating mesh.
The first positioning groove 21 is formed on the inner side of the third plate surface (i.e., the side having the first plate surface and the second plate surface), and the first positioning groove 21 is used for positioning the mounting case 30 on which the sensor 40 is mounted. Therefore, the shape, size, depth, etc. of the first positioning groove 21 can be designed according to the mounting housing 30, for example, in the present embodiment, the mounting housing 30 for mounting the sensor 40 has a substantially rectangular column structure, and thus the first positioning groove 21 has a rectangular groove shape. With respect to the depth of the first positioning groove 21, in some embodiments, the depth of the first positioning groove 21 is approximately between one tenth and one fifth of the height of the mounting shell 30, which can better position the mounting shell 30 and also facilitate the mounting shell 30 to be installed in the first positioning groove 21. The situation that the first positioning groove 21 is too shallow to well position the mounting shell 30 and the situation that the friction is large and the requirement on the mounting angle is high when the mounting shell 30 is installed due to too deep first positioning groove 21 are avoided. Wherein, to the installation shell 30 of rectangle cylinder structure, four angles of installation shell 30 can the radius setting, and is corresponding, four angles of first constant head tank 21 also radius setting, so can enough reduce first constant head tank 21 to the friction of installation shell 30, scrape bump etc. still be convenient for install packing into of shell 30 more.
The first positioning groove 21 may be formed in various ways, for example, by a groove concavely formed on the surface of the mounting panel 20, a fence convexly formed on the surface of the mounting panel 20, or other structures on the mounting panel 20, such as a rib, a guide bar, and a grating. The specific design may be flexible according to the actual structure of the mounting panel 20, and is not limited in this respect.
In the present embodiment, as shown in fig. 4, in order to ensure that the sensor 40 installed inside the installation panel 20 (i.e., the side on which the centrifugal fan or other functional components are installed) can emit a signal to the outside of the installation panel 20 or receive a signal from the outside of the installation panel 20, the bottom of the first positioning groove 21 is further provided with a first signal window 22. The first signal window 22 may be formed by a through hole penetrating the mounting panel 20, may be formed by a structure penetrating the mounting panel 20 and having a lens or a light transmitting member mounted therein, or may be formed by a transparent installation of a partial region on the mounting panel 20. The specific design can be carried out according to actual needs, and is not limited herein.
The shape, size, etc. of the first signal window 22 are not limited herein, and only enough sensor 40 needs to transmit and receive the sensing signal, for example, in the present embodiment, the first signal window 22 has a substantially square structure and is formed by a through hole penetrating the mounting panel 20. The sensor 40 generally includes a transceiver 42, and the size of the first signal window 22 is substantially matched with the transceiver 42 of the sensor 40, so as to ensure smooth signal transceiving, simplify the processing technology and improve the production efficiency.
The mounting housing 30 is positioned in the first positioning groove 21 and is provided with a second signal window 31 opposite to the first signal window 22. In this embodiment, the positioning of the mounting shell 30 in the first positioning groove 21 means that the mounting shell 30 is positioned on the mounting panel 20 by the first positioning groove 21. For example, the size and shape of first constant head tank 21 follow installation shell 30 adaptation, and when installation shell 30 was installed in first constant head tank 21, the outer wall of installation shell 30 and the inner wall butt of first constant head tank 21 or the small clearance interval, first constant head tank 21 had both played the positioning action to installation shell 30, also can play certain supporting role.
Still alternatively, the first positioning groove 21 may be larger than the mounting shell 30, and a rubber pad is disposed between an outer wall of the mounting shell 30 and an inner wall of the first positioning groove 21, so that the mounting shell 30 can be clamped in the first positioning groove 21 through the rubber pad, and thus, the positioning of the mounting shell 30 in the first positioning groove 21 can also be achieved.
In this embodiment, in order to avoid the situation that the mounting shell 30 shakes during the positioning process, the bottom of the first positioning groove 21 and the bottom of the mounting shell 30 (i.e. the surface facing the first signal window 22) can be both configured as planes and abut against each other, so that the positioning stability of the mounting shell 30 in the first positioning groove 21 can be ensured.
The second signal window 31 of the mounting housing 30 is formed, sized, shaped, etc. with reference to the first signal window 22, and will not be described in detail. The second signal window 31 and the first signal window 22 may be formed in the same manner or in different manners. For example, in the present embodiment, the filter lens 313 is disposed in the second signal window 31, and the first signal window 22 is directly formed by a through hole penetrating the mounting panel 20.
The second signal window 31 and the first signal window 22 need to be correspondingly arranged in position to ensure that the sensor 40 in the mounting shell 30 can receive and transmit induction signals through the second signal window 31 and the first signal window 22.
As shown in fig. 6 and 7, the sensor 40 is installed in the mounting case 30, and transmits and receives an induction signal through the first signal window 22 and the second signal window 31. Specifically, a mounting cavity 33 is formed in the mounting shell 30, the second signal window 31 is disposed on a wall of the mounting cavity 33, and the sensor 40 is positioned in the mounting cavity 33 of the mounting shell 30. The sensor 40 is provided with a transceiver 42 for transmitting and receiving signals, and the transceiver 42 of the sensor 40 corresponds in position to the second signal window 31 when the sensor 40 is positioned in the mounting cavity 33.
In order to enable the sensor 40 to be mounted in the mounting cavity 33, as shown in fig. 7 and 8, the mounting case 30 may be provided with a mounting opening 352 communicating with the mounting cavity 33 thereof, and after the sensor 40 is mounted in the mounting cavity 33, the mounting opening 352 is covered by a cover plate or the like to prevent the sensor 40 from being detached from the mounting cavity 33 from the mounting opening 352 of the mounting case 30. Alternatively, the mounting case 30 may be composed of two cases detachably connected, one of the cases is provided with the mounting cavity 33 and the mounting opening 352, and after the sensor 40 is mounted in the mounting cavity 33, the sensor 40 may be pressed in the mounting cavity 33 from the mounting opening 352 by the other case to ensure the mounting stability of the sensor 40.
Of course, from the viewpoint of improving the installation stability of the sensor 40, a positioning structure, a protective rubber pad, and the like may be further disposed in the installation shell 30, so that the sensor 40 is stably installed and can be better protected.
Therefore, in summary, it can be understood that the sensor mounting structure 10 of the present invention first mounts the sensor 40 in the mounting housing 30, and then positions the sensor 40 on the mounting panel 20 of the mobile device 70 together with the mounting housing 30, and the mounting panel 20 is provided with the first positioning groove 21 for positioning the mounting housing 30. When positioning, the mounting housing 30 is directly positioned in the first positioning groove 21, so that the sensor 40 can be accurately positioned. Compared with the installation mode of directly installing the sensor 40 which is small in size, thin in thickness and not easy to fix on the installation panel 20, the installation mode of installing the sensor 40 through the installation shell 30 and the first positioning groove 21 not only can improve the position accuracy and convenience of installation of the sensor 40, but also can protect the sensor 40 through the installation shell 30. The technical problem that the position accuracy of the sensor 40 is difficult to ensure when the sensor 40 is assembled by some existing mobile devices 70 is effectively solved.

In the present embodiment, taking the surface of the mounting housing 30 facing the first signal window 22 as an example of a bottom surface, the first positioning bosses 32 are protruded from the bottom surface of the mounting housing 30, and are similar to the mounting housing 30 in shape and are all rectangular structures. The first positioning boss 32 is positioned in the second positioning groove 23, the bottom surface of the first positioning boss abuts against the bottom of the second positioning groove 23, and the outer peripheral wall of the first positioning boss abuts against the inner peripheral wall of the second positioning groove 23 or a small gap is formed between the outer peripheral wall of the first positioning boss and the inner peripheral wall of the second positioning groove 23.
It can be understood that, because the first signal window 22 is disposed at the bottom of the second positioning groove 23, the second signal window 31 is disposed in the first positioning boss 32, and thus when the first positioning boss 32 is positioned in the second positioning groove 23, the position accuracy between the first signal window 22 and the second signal window 31 can be further ensured.
