[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vehicle-mounted camera module structure 10 with a common bracket includes: a bracket 100 and multiple camera modules 200, the bracket 100 includes a front positioning plate 110 and a bracket back cover 120, the bracket back cover 120 is arranged on a side surface of the front positioning plate 110, and the front positioning plate 110 is provided with multiple positioning holes 111, and the bracket back cover 120 is provided with multiple avoidance holes 121; each camera module 200 is respectively accommodated in each positioning hole 111, and each avoidance hole 121 is used to perform avoidance operation on the connector on each camera module 200, so that the connector on each camera module 200 passes through each avoidance hole 121 and is connected to an external whole machine.

[0025] It should be noted that each camera module 200 is placed in each positioning hole 111, and the relative position of each camera module 200 is positioned through each positioning hole 111, and then connected to the front positioning plate 110 through the bracket back cover 120, so as to limit each camera module through the bracket back cover 120 to prevent the camera module from falling off or shifting. In this way, multiple camera modules can be integrated on the same bracket, and at the same time, the installation efficiency can be improved to a certain extent, and the installation accuracy of the relative position of each camera module 200 can be improved. At the same time, by opening an avoidance hole on the bracket back cover 120, the connector on each camera module 200 is avoided through the avoidance hole, so that the connector on each camera module 200 passes through each avoidance hole 121 and is connected to the external whole machine. For example, the connector is a Fakra plug, and the camera module 200 can be connected to the external whole machine through a coaxial line. In this embodiment, the bracket 100 is a metal frame, so that it can ensure that there is sufficient strength to fix each display module.

[0026] Specifically, the plurality of camera modules 200 respectively include a first conventional field of view module 210, a wide-angle module 220, a telephoto module 230, and a second conventional field of view module 240. Four positioning holes 111 are provided, and the first conventional field of view module 210, the wide-angle module 220, the telephoto module 230, and the second conventional field of view module 240 are respectively accommodated in each positioning hole 111. Similarly, four corresponding avoidance holes 121 are also provided, and the four avoidance holes 121 correspond to four camera modules respectively. Specifically, the first conventional field of view module 210, the wide-angle module 220, the telephoto module 230 and the second conventional field of view module 240 are arranged in sequence from left to right and accommodated in each positioning hole 111, that is, the two conventional field of view modules are located on the left and right sides, and the first conventional field of view module 210 and the second conventional field of view module 240 are used to detect and locate obstacles on the left and right sides of the car to achieve the avoidance of the car; and the wide-angle module 220 and the telephoto module 230 are placed in the middle, wherein the wide-angle module 220 is used for global scanning and detection of all external obstacles; wherein the telephoto module 230 is used to detect far-end obstacles to achieve acceleration or deceleration of the car. When the field of view of the conventional viewing angle module or the telephoto module is superimposed with the wide-angle module, the distance of the obstacle can be calculated by using the binocular imaging principle, thereby achieving positioning.

[0027] For further information, see Figure 4 As shown, each camera module 200 includes a module lens 210 and a module PCB (printed circuit board) board 220. The module lens 210 is arranged on the PCB board 220, and a PCB mounting hole 221 is opened on the PCB board 220.

[0028] It should be noted that, in the present embodiment, each camera module 200 does not need to adopt a common PCB board structure. The reason is that the common PCB board has high requirements on the mounting accuracy of each camera module, and when it is subsequently assembled with the bracket, it limits the accuracy of the bracket opening and the difficulty of assembly (that is, the positioning holes of the bracket need to match the camera modules on the common PCB board one by one). For example, when one tolerance of the camera module on the PCB board is biased to the left and the other tolerance is biased to the right, the iron frame opening may not be able to pass through the module due to tolerance reasons, and it is impossible to adjust each module one by one. Furthermore, when installing each camera module, firstly, the camera lens 210 is passed through the positioning hole 111 from the back side of the front positioning plate 110 (that is, the side of the front positioning plate 110 close to the rear cover of the bracket). The size of the positioning hole 111 is designed to match the size of the module lens 210. For example, the diameter of the positioning hole 111 is 0.5-1mm larger than the diameter of the module lens 210. In this way, the risk of the camera module and the side wall of the positioning hole 111 being scratched can be reduced, and at the same time, the positioning hole 111 can be prevented from being too large, causing the camera module to shake. After the lens group 210 is accommodated in the positioning hole 111, since the size of the PCB board is larger than the positioning hole 111, the PCB board is abutted against the back of the front positioning plate 110. For example, each camera module is respectively fixed to the front positioning plate 110 by screwing. Specifically, a PCB mounting hole 221 is opened on the PCB board, and correspondingly, a front positioning plate mounting hole 112 corresponding to the PCB mounting hole 221 is also opened on the front positioning plate 110. For example, the PCB mounting hole 221 and the front positioning plate mounting hole 112 can be connected and fixed by screws. In this embodiment, two PCB mounting holes 221 are opened, and the two PCB mounting holes 221 are on both sides of the module lens. Similarly, front positioning plate mounting holes 112 are also opened on both sides of each positioning hole 111.

[0029] In one embodiment, please refer to Figure 2 As shown, the vehicle-mounted camera module structure also includes a plurality of buffer blocks 300, each of which is respectively arranged on a side surface of the front positioning plate 110 close to the bracket rear cover 120, and each of which is respectively arranged around each positioning hole. That is, the buffer block 300 is annular in structure. When the module lens 210 passes through the positioning hole 111, the buffer block 300 is used for buffering and sealing to avoid compression damage between the PCB board and the front positioning plate 110. Preferably, the buffer block is a foam buffer block. Preferably, the thickness of the foam buffer block is 0.3-0.5mm, and the width of the foam buffer block is 0.5-1mm.

[0030] Furthermore, the front positioning plate 110 and the bracket rear cover 120 are locked and fixed by screwing. That is, the four corners of the front positioning plate 110 are provided with first mounting holes 113, and the four corners of the bracket rear cover 120 are provided with second mounting holes 122. The first mounting holes 113 and the second mounting holes 122 are aligned, and then the first mounting holes 113 and the second mounting holes 122 can be connected to each other by screwing, such as screws.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
