Description

Technical Field

[0001] The present application relates to the field of vehicle lighting technology, and in particular to a vehicle light circuit board mounting structure, a vehicle light and a vehicle. Background Art

[0002] In the structure of car lights, the electronic circuit board is a very important part.

[0003] Car lights have evolved from the era of light bulbs to the era of LED light sources. Circuit boards have taken over the LED structure, drive component structure, control component structure, etc., and have put the large-scale use of LED light sources on the stage. The electronic components on the circuit board are all high-precision, highly sensitive, and easily damaged. Therefore, the assembly design of the car light circuit board must ensure that it passes the vibration test of the whole vehicle. Ensuring the stability of the components on the surface of the car light circuit board during its life cycle is a crucial part of car light design.

[0004] At present, conventional circuit board fixing methods include hot stamping and cold riveting. These installation methods require a certain air avoidance area. For example, hot stamping and cold riveting require a large safe air avoidance area on the circuit board for the hot stamping / cold riveting equipment. In addition, due to anti-static and worker operation requirements, a large safe air avoidance area is also required on the circuit board. These all limit the effective use space of the circuit board. Utility Model Content

[0005] In order to solve the above problems, the technical solutions adopted in the embodiments of the present application are as follows:

[0006] The present application discloses a vehicle light circuit board mounting structure, comprising:

[0007] Circuit board;

[0008] A mounting bracket, disposed on the back of the circuit board, for supporting the circuit board;

[0009] There are multiple buffer components, which are distributed in the space between the mounting bracket and the circuit board and are used to provide buffering for the movement of the circuit board relative to the mounting bracket;

[0010] The connecting clamp is arranged at the edge of the mounting bracket and the circuit board and connects the mounting bracket and the circuit board so as to clamp and fix the buffer component between the mounting bracket and the circuit board.

[0011] In this embodiment, compared with the traditional hard-to-hard installation methods such as hot stamping and cold riveting, the buffer component can provide a certain buffering effect, improve the stability and service life of the components on the surface of the circuit board, and increase the stability of the light circuit board after assembly, ensuring that the components on the surface can work normally even in a vehicle with severe vibration;

[0012] By using the connecting clamp in conjunction with the buffer component, there is no need to reserve a safe escape area on the surface of the circuit board, thereby not occupying the surface space of the circuit board, and significantly increasing the effective use space of the circuit board; at the same time, since the space occupied by the connecting clamp is very small, the larger the size of the circuit board, the higher the effective use rate of the surface space of the circuit board, so this installation solution is particularly suitable for the assembly of large-sized circuit boards.

[0013] As an optional implementation, in an embodiment of the utility model, the projection of the circuit board on the surface of the mounting bracket is within a range defined by an edge of the mounting bracket.

[0014] As an optional implementation, in an embodiment of the utility model, the circuit board overlaps with the mounting bracket, and the projection of the edge of the circuit board on the surface of the mounting bracket coincides with the edge of the mounting bracket.

[0015] As an optional implementation, in an embodiment of the present utility model, the buffer component is evenly distributed in the space between the mounting bracket and the circuit board.

[0016] As an optional implementation, in the embodiment of the utility model, the distance between two adjacent buffer components is 8-15 mm.

[0017] As an optional implementation, in the embodiment of the utility model, the buffer component includes a square buffer block, and the side length of the square buffer block is 3-5 mm.

[0018] As an optional implementation, in an embodiment of the utility model, there are multiple connecting clamps, which are distributed at intervals on the long side edges and four corners of the circuit board.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] refer to Figure 1 , the present application provides a vehicle light circuit board mounting structure, comprising:

[0038] Circuit board 100;

[0039] A mounting bracket 200 is disposed on the back of the circuit board 100 and is used to support the circuit board 100;

[0040] There are multiple buffer components 300, which are distributed in the space between the mounting bracket 200 and the circuit board 100, and are used to provide buffering for the movement of the circuit board 100 relative to the mounting bracket 200;

[0041] The connecting clamp 400 is disposed at the edges of the mounting bracket 200 and the circuit board 100 and connects the mounting bracket 200 and the circuit board 100 to clamp and fix the buffer component 300 between the mounting bracket 200 and the circuit board 100 .

[0042] In this embodiment, compared with the traditional installation methods such as hot stamping and cold riveting, the buffer component 300 can provide a certain buffering effect, improve the stability and service life of the components on the surface of the circuit board 100, and increase the stability of the light circuit board 100 after assembly, ensuring that the components on the surface can work normally even in a vehicle with severe vibration;

[0043] In the present embodiment, by using the connecting clamp 400 in conjunction with the buffer component 300, there is no need to reserve a safe airspace on the surface of the circuit board 100, thereby not occupying the surface space of the circuit board 100, and significantly increasing the effective use space of the circuit board 100; at the same time, since the space occupied by the connecting clamp 400 is very small, as the size of the circuit board 100 is larger, the effective use rate of the surface space of the circuit board 100 is higher, and therefore this installation scheme is particularly suitable for the assembly of large-sized circuit boards 100.

[0044] In such Figure 1 In one embodiment, the projection of the circuit board 100 on the surface of the mounting bracket 200 is within the range defined by the edge of the mounting bracket 200. In this embodiment, the projection of the circuit board 100 falls within the range defined by the edge of the mounting bracket 200, that is, the surface area of ​​the circuit board 100 is less than or equal to the surface area of ​​the mounting bracket 200, so that the mounting bracket 200 can provide protection for the edges of the circuit board 100 to avoid contact with adjacent components and damage.

[0045] In such Figure 1 In one embodiment, the circuit board 100 overlaps with the mounting bracket 200, and the projection of the edge of the circuit board 100 on the surface of the mounting bracket 200 coincides with the edge of the mounting bracket 200. In this embodiment, the circuit board 100 and the mounting bracket 200 overlap in parallel and their edges coincide, that is, the area of ​​the mounting bracket 200 used is the same as that of the circuit board 100, while ensuring protection of the edges around the circuit board 100, the area and specifications of the mounting bracket 200 are minimized, which is conducive to cost saving.

[0046] In such Figure 2 and Figure 3 In one embodiment, the buffer components 300 are evenly distributed in the space between the mounting bracket 200 and the circuit board 100. Multiple buffer components 300 are evenly distributed, and can provide even support for different positions on the circuit board 100 from the back of the circuit board 100, and provide the same uniform buffering effect for each position on the back of the circuit board 100, thereby avoiding the situation where the local buffering effect is poor and causes local vibration damage.

[0047] Preferably, the spacing between two adjacent buffer components 300 is 8-15 mm. With a spacing of 8-15 mm, the layout density of the multiple buffer components 300 is appropriate, and the layout density will not be too low to cause the area between the two buffer components 300 to be unable to be effectively supported and buffered, and the layout density will not be too high to increase the cost. It has been verified that after adopting this spacing, the circuit board 100 as a whole can achieve the expected buffer support effect.

[0048] In such Figure 2 In one embodiment, the buffer component 300 includes a square buffer block. The square buffer block has a simple structure, is easy to mass produce, and is easy to ensure uniform specifications. Preferably, the size of the square buffer block is 3-5 mm. It has been verified that after adopting this size, the circuit board 100 as a whole can achieve the expected buffer support effect.

[0049] The specific material of the above-mentioned buffer block can be selected from polyurethane, foam material and other materials with deformable and rebound functions, which is not limited here.

[0050] In such Figure 1 In one embodiment, there are a plurality of connecting clamps 400, which are spaced apart at the long side edges and four corners of the circuit board 100. The connecting clamps 400 spaced apart at the long side edges and four corners of the circuit board 100 can fix various parts of the edge of the circuit board 100 to the mounting bracket 200, ensuring that the circuit board 100 and the mounting bracket 200 are firmly mounted and fixed.

[0051] As a preferred embodiment, the connecting clamp 400 is a screw. The screw has a simple structure and can be operated to pass through the circuit board 100 and the mounting bracket 200 in sequence to connect the mounting bracket 200 and the circuit board 100, and at the same time, the buffer component 300 is clamped and fixed between the mounting bracket 200 and the circuit board 100. Of course, the connecting clamp 400 can also be a connecting card or a fixing clip, etc., which is not limited here.

[0052] The present application also discloses a vehicle lamp, comprising the vehicle lamp circuit board mounting structure in any of the aforementioned embodiments.

[0053] The present application also discloses a vehicle, comprising the vehicle light in any of the aforementioned embodiments.

[0054] The vehicle of this embodiment adopts a headlight circuit board installation structure, and the buffer component 300 can provide a certain buffering effect, improve the stability and service life of the components on the surface of the circuit board 100, and can increase the stability of the headlight circuit board 100 after assembly, ensuring that the components on the surface can work normally even in a vehicle with severe vibrations;

[0055] By using the connecting clamp 400 in conjunction with the buffer component 300, there is no need to reserve a safe escape area on the surface of the circuit board 100, thereby not occupying the surface space of the circuit board 100, and significantly increasing the effective use space of the circuit board 100; at the same time, since the space occupied by the connecting clamp 400 is very small, the larger the size of the circuit board 100, the higher the effective use rate of the surface space of the circuit board 100, so this installation solution is particularly suitable for the assembly of large-sized circuit boards.

[0056] It should be noted that the above-mentioned means of transportation may be a car, a train, a high-speed train or other means of transportation that requires headlights.
