Description

Technical Field

[0001] The utility model relates to the field of automotive warning light technology, and in particular to a blind spot warning light. Background Technology

[0002] Blind spot warning lights are the visual cue component of a blind spot monitoring system. They are primarily used to alert the driver when a vehicle (or other object) enters the blind spot from the side or rear, preventing collisions during lane changes and enhancing driving safety, especially at high speeds, in rainy or foggy weather, or at night. They are typically installed on the inside of the exterior rearview mirror lens, A-pillar, dashboard, taillight assembly, or fender. To ensure long-term reliability, manufacturers generally use a sealed design, but this also leads to maintenance difficulties. Once internal components, such as LED beads or circuit boards, are damaged, the entire system often needs to be replaced, resulting in high repair costs.

[0003] The technical content disclosed in Chinese patent document (publication number: CN213019468U, patent name: a waterproof automotive blind spot warning light) is as follows: the upper end of the lamp holder is provided with an outer lens, the lower end of the outer lens is provided with an inner flange, the inner flange is embedded in the lamp holder and fixed by laser welding. The diffusion film is pasted on the outer surface of the outer lens.

[0004] As can be seen from the above implementation plan and corresponding drawings, in order to ensure its waterproof performance, the blind spot warning light of the car needs to be fixed by laser welding after the lamp holder and the outer lens are installed together. This makes the installation process more complicated and requires high skills from the operator. Furthermore, if the lamp holder is damaged and needs to be replaced in the future, the lamp holder cannot be disassembled, resulting in high maintenance costs. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and provides a blind spot warning light. By connecting the circuit board fixing holes, the reflector fixing post and the positioning post, the lamp housing, the circuit board assembly and the reflector are securely assembled. This not only ensures the sealing of the lamp housing, but also facilitates the quick disassembly of the circuit board assembly and the reflector during maintenance, making it convenient to repair and replace the internal parts of the lamp housing.

[0006] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0007] A blind spot warning light includes a lamp housing, a reflector cup nested inside the lamp housing, and a circuit board assembly embedded on the top of the lamp housing. The circuit board assembly is flush with the opening of the lamp housing and covers the reflector cup.

[0008] The lamp housing is equipped with a positioning post, the reflector is equipped with a reflector fixing post, and the circuit board assembly is equipped with a circuit board fixing hole. The positioning post, the reflector fixing post and the circuit board fixing hole are coaxially connected together to achieve a fast assembly of the three.

[0009] Furthermore, the upper end of the lamp housing is provided with a circuit board positioning groove, and the inner edge of the circuit board positioning groove is provided with an arc segment and a straight segment connected to form a closed loop.

[0010] The circuit board assembly is provided with a mating edge, which is a closed loop formed by connecting the first and last parts of a mating arc segment and a mating straight segment;

[0011] The fitting edge matches the inner edge, allowing the circuit board assembly to be fitted into the circuit board positioning groove.

[0012] Furthermore, the depth of the circuit board positioning groove is greater than or equal to the thickness of the circuit board assembly.

[0013] Furthermore, the circuit board assembly has a light-transmitting hole in the middle for light transmission.

[0014] Furthermore, the lamp housing is also provided with a U-shaped hole, through which the circuit board assembly connects the wiring harness, which extends from the lamp housing through the U-shaped hole to the outside of the lamp housing.

[0015] Furthermore, one end of the wire harness is provided with a terminal, which is connected to a two-pin connector.

[0016] Furthermore, the reflector cup is equipped with a multi-faceted reflector inside. The reflector cup is made of pure white ABS material, and the multi-faceted reflector adopts a microprism structure or a honeycomb reflective structure to improve the uniformity of light and the illumination range.

[0017] The lamp housing is made of black ABS material.

[0018] Furthermore, the side of the circuit board assembly away from the reflector is connected to the diffuser assembly, which is a frosted lens or a microstructure optical diffuser, used to eliminate glare from the LED point light source and make the light soft and uniform.

[0019] Furthermore, one side of the light-diffusing assembly is provided with adhesive backing, which is used to bond the light-diffusing assembly to the circuit board assembly.

[0020] Furthermore, a waterproof plug is provided at the U-shaped hole.

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] 1. By connecting the circuit board fixing holes, the reflector fixing post, and the positioning post, the lamp housing, circuit board assembly, and reflector are securely assembled. This ensures the internal sealing of the lamp housing and facilitates quick disassembly of the circuit board assembly and reflector during maintenance, making it convenient to repair and replace internal parts of the lamp housing.

[0023] 2. The mating edge of the circuit board assembly matches the inner edge of the circuit board positioning groove, and the depth of the circuit board positioning groove is appropriate to ensure that the circuit board assembly can be firmly mated and remain flat.

[0024] 3. The waterproof plug at the U-shaped hole enhances the waterproof and dustproof function of the lamp housing, while also providing cushioning for the wiring harness to prevent it from being damaged by friction.

[0025] 4. The diffuser uses a frosted lens or a microstructured optical diffuser to eliminate glare from LED point light sources, making the light soft and uniform and expanding the illumination range; the reflector uses a high reflectivity material, and the multifaceted reflector uses a microprism or honeycomb reflective structure to improve the uniformity of light and the illumination range.
