[0002] At present, the circuit boards of automotive lamps in the market are mostly installed vertically, but some projects must be installed sideways according to customer requirements or insufficient space.

[0003] However, the circuit boards of most lamps use a hook structure. This structure has problems such as the hook easily breaking during installation, the circuit board being difficult to install, the circuit board becoming loose and making strange noises after installation, the PIN pins being crooked after assembly, and the customer's connectors being difficult to install, which leads to customer complaints, returns, rework and other problems.

[0004] Therefore, those skilled in the art provide an automobile lamp circuit board mounting structure to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose an automobile lamp circuit board installation structure to solve the problems of difficult circuit board installation, loose and abnormal noise after circuit board assembly, skewed PIN pins after circuit board assembly, and difficult installation of customer connectors, while reducing customer complaints and returns, improving customer satisfaction, improving production efficiency and qualification rate and reducing costs.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A circuit board mounting structure for automobile lamps, comprising a lamp body and a circuit board, wherein a square heat riveting structure is fixedly arranged at the rear end of one side of the interior of the lamp body, two lamp body avoidance PIN needle structures are arranged at the front end of one side of the interior of the lamp body, a circuit board blocking structure is fixedly arranged at the front and rear ends and the midpoint of the inner wall of the lamp body, and three limit structures are arranged at the lower end of the interior of the lamp body;

[0008] A clearance hole is provided at the rear end of one side of the circuit board, and two PIN needles are fixedly provided at the front end of the other side of the circuit board;

[0009] Through the above technical scheme, the circuit board and the lamp body are fixed by using a limiting structure, a circuit board blocking structure, a lamp body avoiding PIN needle structure, a circuit board avoiding hole structure and a square hot riveting structure. The limiting structure, the circuit board blocking structure and the hot riveting structure can prevent abnormal noise from the circuit board, and the lamp body avoiding PIN needle structure and the circuit board avoiding hole structure can prevent the PIN needle from tilting after assembly.

[0010] Furthermore, a connector is embedded in one side of the outer wall of the lamp body near the front end;

[0011] Through the above technical solution, the connector is a standard part and can be quickly installed and disassembled for use.

[0012] Furthermore, the two PIN pins are respectively embedded in two lamp body PIN pin avoidance structures;

[0013] Through the above technical solution, the PIN needle can be protected and restricted to avoid deflection caused by collision.

[0014] Furthermore, the square heat riveting structure is arranged in the air-avoiding hole, and the circuit board and the lamp body are fixed as one body after being heat-riveted by the square heat riveting structure;

[0015] The above technical solution is helpful to quickly install and fix the circuit board and the lamp body for use.

[0016] Furthermore, the circuit board is embedded between two circuit board blocking structures located at the front and rear ends of the three circuit board blocking structures, and one side of the circuit board is connected to the circuit board blocking structure located in the middle position;

[0017] The above technical solution has a limiting effect on the circuit board, and the circuit board blocking structure located in the middle position limits the maximum movement position of the circuit board installation to avoid excessive movement distance.

[0018] Furthermore, when the circuit board is located between the circuit board blocking structures, the three limiting structures are located at the lower end of the circuit board and the limiting structures restrict the clamping of one side of the circuit board;

[0019] Through the above technical solution, the circuit board can be restricted and fixed, and the abnormal noise caused by the shaking of the circuit board can be reduced.

[0020] The utility model has the following beneficial effects:

[0031] An air avoidance hole 1-2 is opened at the rear end of one side of the circuit board 1, and two PIN needles 1-1 are fixedly arranged at the front end of the other side of the circuit board 1. The material of the circuit board 1 is FR4, and the material of the lamp body 2 is ABS.

[0032] Specifically, when installing the circuit board 1, first put the circuit board 1 into the lamp body 2, and align the two PIN pins 1-1 and the air avoidance hole 1-2 on one side of the circuit board 1 with the corresponding lamp body avoidance PIN pin structure 6 and the square heat riveting structure 7 in the lamp body 2. Since the two PIN pins 1-1 are respectively embedded in the two lamp body avoidance PIN pin structures 6, the square heat riveting structure 7 is penetrated in the air avoidance hole 1-2, and the circuit board 1 and the lamp body 2 are fixed as a whole after being heat-riveted and connected by the square heat riveting structure 7;

[0033] At this time, the circuit board 1 is pushed toward the direction close to the lamp body avoidance PIN needle structure 6 and the square heat riveting structure 7, so that the two PIN needles 1-1 are inserted into the lamp body avoidance PIN needle structure 6, and the square heat riveting structure 7 passes through the avoidance hole 1-2 and is fixed into an integrated structure by heat riveting.

[0034] Specifically, a connector 3 is embedded in one side of the outer wall of the lamp body 2 near the front end. The connector 3 is a standard body. Since the circuit board 1 is embedded between the two circuit board blocking structures 5 located at the front and rear ends of the three circuit board blocking structures 5 and one side of the circuit board 1 is connected to the circuit board blocking structure 5 located in the middle position, and when the circuit board 1 is located between the circuit board blocking structures 5, the three limiting structures 4 are located at the lower end of the circuit board 1 and the limiting structures 4 complete the clamping restriction on one side of the circuit board 1. That is, the circuit board 1 is blocked by the circuit board blocking structure 5, so that it is placed in the limiting structure 4 and clamped, so that the circuit board 1 can be prevented from making abnormal noises by using the limiting structure 4, the circuit board blocking structure 5 and the square hot riveting structure 7.

[0035] Working principle: During installation, place the circuit board 1 into the lamp body 2, place the PIN needle 1-1 into the PIN needle avoidance structure 6 of the lamp body, and pass the square hot riveting structure 7 through the air avoidance hole 1-2 of the circuit board 1. At this time, the circuit board 1 is blocked by the circuit board blocking structure 5, and the lower end of the circuit board 1 is placed in the limiting structure 4 to be restricted and fixed, and the square hot riveting structure 7 fixes the circuit board 1 and the lamp body 2 as a whole after hot riveting.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
