Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a novel screw-based light-blocking structure. Background Technology

[0002] Currently, the traditional optical solutions for position lights and reversing lights mainly adopt the following optical structure design: the position light uses a side-emitting light source + reflector + internal lens to form the position light optical solution, while the reversing light uses a side-reflecting light source + thick-walled component to form the reversing light optical solution. This traditional optical solution for position lights and reversing lights can share a single PCB board, which can save costs. However, the thick-walled component and the PCB board are mostly connected by snap-fit ​​or riveting, which has the problem of light leakage between the thick-walled component and the reflector. Utility Model Content

[0003] The purpose of this invention is to provide a novel screw-based light-blocking structure, which aims to solve the problem of light leakage caused by the shared PCB board in traditional position lights and reversing lights.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] This utility model designs a novel screw light-blocking structure, which includes the following structural configuration:

[0006] PCB board, which has a first surface and a second surface opposite to each other;

[0007] A position light source, which is welded to the first surface;

[0008] A reflector bowl, disposed on the first surface, is used to reflect the light emitted by the position light source to realize the position light function;

[0009] The reversing light source is welded to the second surface;

[0010] A thick-walled component has an assembly end, which is disposed on one side of the second surface. The assembly end penetrates the first and second surfaces to realize the assembly of the thick-walled component with the PCB board. The thick-walled component is used to conduct the light emitted by the reversing light source to realize the reversing light function.

[0011] And a light-blocking device, which is disposed on one side of the first surface, the light-blocking device is also connected to the assembly end, for shielding the assembly point of the thick-walled component and the PCB board to prevent light leakage.

[0012] Specifically, this utility model is a solution proposed based on the technical problem that occurs when two different optical schemes for position lights and reversing lights share a PCB board, resulting in light leakage between the thick-walled component and the reflector.

[0013] Furthermore, a novel screw light-blocking structure is provided: a positioning post is also provided on the assembly end, the positioning post penetrates through the first surface and the second surface, the assembly end abuts against the second surface, and the light-blocking device is also used to shield the positioning post.

[0014] Specifically, the positioning posts can enhance the structural stability of the thick-walled component after it is assembled with the PCB board.

[0015] Furthermore, a novel screw-based light-blocking structure is proposed: the light-blocking device is configured as a large pan head screw.

[0016] The beneficial effects of this utility model are:

[0017] This novel screw-based light-blocking structure allows for the sharing of a single PCB board for both position lights and reversing lights, saving costs. Furthermore, the design connects the thick-walled component to the PCB board via a light-blocking device, achieving both secure fastening of the thick-walled component and shielding it. This solves the problem of light leakage between the thick-walled component and the reflector bowl, thus resolving the light leakage issue that arises when position lights and reversing lights share a single PCB board.

[0018] This novel screw-based light-blocking structure, designed in this utility model, not only connects thick-walled components but also blocks light by using a light-blocking device (large pan head screw). This avoids the need for additional light-blocking parts, saves costs, reduces the number of parts, saves internal space in the headlight, and simplifies the assembly process.

[0027] Example 1

[0028] like Figures 1-4 As shown, a novel screw-based light-blocking structure includes the following specific structural configuration:

[0029] PCB board 1, which has opposing first surface 11 and second surface 12;

[0030] Position light source 2, which is soldered to the first surface 11 of the PCB board 1;

[0031] A reflector bowl 3 is disposed on the first surface 11 to reflect the light emitted by the position light source 2, so as to realize the position light function;

[0032] The reversing light source 4 is welded to the second surface 12;

[0033] A thick-walled component 5 is disposed on one side of the second surface 12. The thick-walled component 5 has an assembly end 51 and a positioning post 52 is disposed on the assembly end 51. The positioning post 52 penetrates the first surface 11 and the second surface 12. The assembly end 51 abuts against the second surface 12 to achieve stable assembly of the thick-walled component 5 and the PCB board 1. The thick-walled component 5 is used to conduct the light emitted by the reversing light source 4 to realize the reversing light function.

[0034] And a light-blocking device (using a large pan head screw) 6, which is disposed on one side of the first surface 11. The light-blocking device 6 is also threadedly connected to the assembly end 51 to fasten the thick-walled component 5, while shielding the assembly point of the thick-walled component 5 and the PCB board 1 (the light-blocking device 6 mainly shields the positioning post 52) ​​to prevent light leakage.

[0035] Specifically, in the novel screw-based light-blocking structure designed in Example 1, both the position light source 2 and the reversing light source 4 use LEDs as light sources, and the two light sources with different functions (position light source 2 and reversing light source 4) share a single PCB board 1.

[0036] When the reversing light source 4 is turned on, the light emitted by the reversing light source 4 is conducted through the thick-walled component 5 to realize the reversing light function. When some light reaches the positioning post 52 of the PCB board 1 and the thick-walled component 5, the light is blocked by the light blocking device (large pan head screw) 6 and cannot reach the reflector bowl 3 side, thus achieving the effect of preventing the light conducted in the thick-walled component 5 from entering the reflector bowl 3 side.

[0037] When the position light source 2 is lit, the light emitted by the position light source 2 generates some stray light through the reflector bowl 3. When the light reaches the light blocking device (large pan head screw) 6, the light is blocked and cannot reach the positioning post 52 of the thick wall part 5, thereby avoiding the light from the two different functional areas of the position light and the reversing light from interfering with each other, and achieving the light blocking effect.

[0038] The novel screw-type light-blocking structure designed in Example 1 prevents light from two different functional light sources from passing through the positioning post of the thick-walled component. The design of the light-blocking device achieves both stable assembly of the thick-walled component 5 and the PCB board 1, and provides the light-blocking function, thus avoiding the need for additional light-blocking parts, reducing the number of parts, saving costs, and conserving internal space in the vehicle lamp. This novel screw-type light-blocking structure improves the component composition of the light-blocking structure, reduces the number of parts, lowers costs, and saves internal space in the lamp.

[0039] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
