Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera assembly structure. Background Art

[0002] In the car camera, the circuit board is connected to the terminal of the back shell through the PCB terminal seat. Due to the processing tolerance of each part, the parts assembly process will be affected by the cumulative tolerance, resulting in misalignment between the PCB terminal seat and the back shell terminal. If the assembly is forced, the terminal seat will be stressed, resulting in the risk of pads falling off and electronic components being damaged, affecting the reliability of the product.

[0003] At present, the industry usually uses floating contact terminals to absorb the accumulated tolerance to ensure the assembly accuracy of the camera, and then uses the positioning pins of the camera and the limiting holes of the fixing seat to meet the accuracy requirements of the product after assembly. However, this solution has problems such as high cost of floating contact terminals, few mature products in the market, and unstable contact reliability, which will affect product performance such as EMC and insufficient anti-interference ability. Utility Model Content

[0004] The purpose of the utility model is to provide a camera assembly structure to solve the problems existing in the prior art, eliminate the influence of the camera cumulative tolerance on assembly in a low-cost manner, and ensure the reliability and anti-interference performance of the product.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A camera assembly structure comprises a camera body, a fixing seat and a jig; the camera body comprises a front shell and a rear shell, and a PCB board and a fixed terminal respectively arranged in the front shell and the rear shell, and the PCB board is provided with a terminal seat; a gap is reserved at the joint between the front shell and the rear shell for the rear shell to move relative to the front shell so that the fixed terminal and the terminal seat are coaxially plugged, and the joint is sealed and connected after the fixed terminal and the terminal seat are plugged; the jig is provided with a positioning groove for positioning and matching the front shell; the jig is provided with a plurality of positioning pins arranged along the axial direction of the camera body; the fixing seat is matched with the surface of the rear shell facing away from the front shell and is provided with a positioning hole for the positioning pin to be embedded.

[0007] The front shell is used for installing the lens of the camera.

[0008] The seam between the front shell and the rear shell is welded by laser to form a sealed connection structure.

[0009] The fixing seat is provided with a through hole for the fixed terminal to pass through.

[0010] The camera assembly structure also includes a plurality of pressure strips detachably connected to the fixture, and the pressure strips press and fix the fixing seat on the fixture.

[0011] After adopting the above technical solution, the utility model has the following technical effects:

[0012] (1) The utility model reserves a gap at the joint between the front shell and the rear shell for the rear shell to move relative to the front shell so that the fixed terminal and the terminal seat can be coaxially plugged in. This allows the rear shell to float relative to the front shell and the terminal seat therein, and can absorb the accumulated tolerance when the fixed terminal is installed on the rear shell, ensuring that the fixed terminal can be coaxially plugged in with the terminal seat without being subject to radial forces. At the same time, the cost of the fixed terminal is lower and it has market competitiveness.

[0013] (2) By using a jig to position the front shell of the camera body and the positioning holes of the fixing seat respectively, the front shell, i.e., the camera body, and the fixing seat are indirectly fixed relative to each other, which can eliminate the floating effect of the rear shell and reduce the effect of the dimension chain, thereby improving the position accuracy of the image sensor and the fixing seat on the PCB board image and improving the assembly accuracy of the product after the camera body and the fixing seat are assembled.
