Description

Technical Field

[0001] This utility model relates to the field of automotive lighting, and in particular to a vehicle headlight reflector mechanism. Background Technology

[0002] As the most common means of transportation today, automobiles provide convenience for people's travel. However, during the driving process, it is inevitable to encounter situations with poor lighting, such as at night or in tunnels. In these cases, it is necessary to use automobile lights to illuminate the road so that drivers can better observe road conditions. To fully illuminate the road ahead, existing automobile lights have reflectors installed on the outside of the lights. When the light shines in the center of the reflector, the reflector can focus the light and fully illuminate the road ahead. The entire reflective structure design of the car lights is complex, especially for the use of narrow and elongated lamp bodies in some car lights. Traditional lamp designs can no longer meet the requirements of modern intelligent vehicle lighting design, let alone modular design and installation. Utility Model Content

[0005] Furthermore: the mounting base plate is provided with high-precision pins, and the groove wall of the mounting slot is provided with positioning slots for the high-precision pins to be engaged.

[0006] Furthermore: the surface of the lamp housing is also provided with an auxiliary limiting groove for fastening the supporting base plate, the surface of the supporting base plate is provided with an auxiliary boss, and the bottom of the auxiliary limiting groove is provided with a stepped groove for the auxiliary boss to be inserted.

[0007] Furthermore, the reflective lamp cover is provided with multiple spliced ​​reflective blocks.

[0008] Furthermore, the side of the supporting substrate is provided with an auxiliary heat dissipation block.

[0009] Furthermore, the opening of the independent lamp chamber is also provided with a light-shielding edge block.

[0010] In summary, this utility model has the following beneficial effects:

[0011] By combining independent lamp chambers and light source modules, a working mechanism for generating and reflecting light can be formed, achieving a high degree of integration and modularity while ensuring the stable and efficient working performance of the vehicle lamp body.

[0012] The light source module and the lamp housing are connected by a detachable mounting structure, which not only facilitates disassembly and assembly, but also improves the tightness of the light source module installation and its daily anti-shake and anti-vibration effect by relying on the limiting support of the mounting base and the support base.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: A vehicle headlight reflector mechanism, such as Figure 1 As shown, it includes a lamp housing 1, and multiple independent lamp chambers 2 are provided inside the lamp housing 1. The light sources of the multiple independent lamp chambers 2 form a converged beam to meet the lighting effect during vehicle operation.

[0020] like Figure 1 , Figure 3 and Figure 4As shown, a reflector lampshade 3 is provided inside the independent lamp chamber 2, and a focusing lens 4 is provided at the opening of the independent lamp chamber 2. A mounting slot 5 is provided on the lamp housing 1 located above the independent lamp chamber 2, and a light source module 6 is detachably connected to the mounting slot 5. The light emitted by the light source module 6 is refracted by the reflector lampshade 3 and then emitted through the focusing lens 4. To improve the uniformity of the emitted light, multiple spliced ​​reflective blocks 19 are provided inside the reflector lampshade 3, which can fully diffuse the light emitted by the light source module 6. Furthermore, a light-shielding edge block 21 is provided at the opening of the independent lamp chamber 2 to limit and constrain the light emission range, ensuring a stable and reliable focused illumination effect.

[0021] like Figure 1 and Figure 2 As shown, the light source module 6 includes a mounting base plate 7, a support base plate 8, a heat sink 9, a power interface block 10, an LED light source block 11, and a PCB control board 12. The mounting base plate 7 is provided with bolt locking holes 13 that are movably connected to the lamp housing 1. Installers can achieve stable fastening and limiting by assembling the components through the bolt locking holes. All components in the light source module 6 are integrated into the mounting base plate 7, realizing a high degree of modularity and integration of the automotive lamp light source components. The LED light source block 11 and the PCB control board 12 are electrically connected by leads, realizing the on / off of the light source under the command output of the PCB control board 12. The heat sink 9 is located on the side of the mounting base plate 7 away from the PCB control board 12, realizing stable heat dissipation and cooling during the operation of the light source module 6, and preventing the components from overheating and affecting the normal light emission operation.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, to further improve the compact fit between the light source module 6 and the lamp housing 1, the mounting base 7 is provided with high-precision pins 14, and the groove wall of the mounting slot 5 is provided with positioning slots 15 for the high-precision pins 14 to engage, satisfying the engagement of the high-precision pins 14 and the positioning slots 15, improving assembly accuracy and anti-vibration performance during use. Furthermore, the surface of the lamp housing 1 is also provided with an auxiliary limiting groove 16 for engaging with the supporting base plate 8, and the surface of the supporting base plate 8 is provided with an auxiliary boss 17. The bottom of the auxiliary limiting groove 16 is provided with a stepped groove 18 for the auxiliary boss 17 to insert into. The supporting base plate 8 further improves the overall stability of the light source module 6, ensuring reliable and coordinated operation between the light source module 6 and the lamp housing 1. Simultaneously, the side of the supporting base plate 8 is provided with an auxiliary heat sink 20, which can supplement the heat dissipation of the heat sink 9, achieving stable heat dissipation performance of the vehicle lamp during long-duration operation.
