Description

Technical Field

[0001] This utility model relates to the field of automotive lighting production technology, and in particular to an integrated automotive lighting device. Background Technology

[0002] In existing technologies, automotive lighting devices have always been used in separate low beam, high beam, bi-beam, and ADB lamp modes. This traditional approach requires various types of dimming fine-tuning structures for the modules. However, the traditional design, which involves installing the two functional modules separately for fine-tuning, occupies a large space, has complex parts, and is costly. It also fails to achieve the aesthetic appeal and compactness of an integrated design. The gap between the two functional modules is large, taking up a lot of space, and fine-tuning between the two functional modules requires other dimming components, which are complex in structure and require high precision. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated vehicle lighting device that combines a dual-beam module and an adaptive high beam module into one, simplifying the dimming mechanism between the modules.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An integrated vehicle lighting device includes a lens assembly, a radiator assembly mounted at the rear end of the lens assembly, and a first light-emitting module and a second light-emitting module disposed at the front end of the radiator assembly.

[0006] The front end of the lens assembly is equipped with a first lens that aligns with the first light-emitting module and a second lens that aligns with the second light-emitting module.

[0007] An adjustment bracket is movably mounted in the middle of the lens support, and a third lens aligned with the first lens is mounted in front of the adjustment bracket. The adjustment bracket can be adjusted along the light output direction for focusing.

[0008] Furthermore, a slot is provided in the middle of the lens support, and the adjustment bracket is inserted into the lens support from the slot.

[0009] Furthermore, a positioning plate is provided on the edge of the lens support near the slot, and a matching plate is provided on the side wall of the adjustment support, with the matching plate in limiting contact with the positioning plate.

[0010] Furthermore, the positioning plate is provided with a limiting post, and the positioning plate is provided with a limiting sliding hole that cooperates with the limiting post.

[0011] Furthermore, the mounting plate is also provided with a locking hole, and a countersunk screw suitable for locking the mounting plate and the positioning plate is provided in the locking hole.

[0012] Furthermore, both the first lens and the second lens are fixed to the front end of the lens assembly bracket by metal clips.

[0013] Furthermore, the first light-emitting module includes a silicone inner lamp cover, a first mounting bracket, a light-blocking sheet, and a first PCBA that are assembled together.

[0014] Furthermore, the second light-emitting module includes a low beam baffle, a second mounting bracket, an inner lamp cover, and a second PCBA that are assembled together.

[0015] Furthermore, the radiator assembly includes a first radiator, a second radiator, a first assembly plate for mounting the first radiator, and a second assembly plate for mounting the second radiator.

[0016] Furthermore, the first light-emitting module is installed on the front side of the first assembly plate, the second light-emitting module is installed on the front side of the second assembly plate, and the periphery of the first and second assembly plates is assembled with the lens support.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. This utility model combines a lens assembly with an adjustment bracket, and an annealer assembly with the lens assembly. The lens assembly holds the first and second lenses, while the adjustment bracket holds the third lens and aligns it with the first lens. This allows for focusing by adjusting the adjustment bracket and the third lens along the light output direction. This structural combination integrates the original dual-beam module and adaptive high-beam module into one unit. While maintaining all functions, it simplifies the dimming mechanism between modules, eliminates traditional fine-tuning parts, and achieves true integrated design through component design and tooling coordination.

[0019] 2. Compared with the original multi-structure module, the overall structure of this utility model can reduce the space occupied by the module in the whole lamp environment, occupy less space, simplify the parts, reduce the cost, and combine the aesthetics and compactness of integrated design.

[0020] 3. This utility model can simultaneously realize the functions of high beam, low beam, and adaptive high beam, and can form a better optical effect on the road surface, completing the splicing of the ADB and the low beam cutoff line, bringing drivers a better and safer night driving experience.

Detailed Implementation

[0028] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1-5 As shown in this embodiment, an integrated vehicle lighting device is provided, which mainly consists of a lens assembly 1, an adjustment bracket 2, a first lens 31, a second lens 32, a third lens 33, a heat sink assembly, a first light-emitting module, and a second light-emitting module. The first lens 31 is mounted on the lower front end of the lens assembly 1, and its edge is fixed by a metal clip 4. The second lens 32 is mounted on the upper front end of the lens assembly 1, and its edge is also fixed by a metal clip 4. The heat sink assembly is assembled at the rear end of the lens assembly 1, and the first and second light-emitting modules are mounted on the front end of the heat sink assembly, with the first lens 31 and the second lens 32 aligned with each other. Simultaneously, the adjustment bracket 2 is movably mounted in the middle of the lens assembly 1, and the third lens 33, aligned with the first lens 31, is mounted on the front of the adjustment bracket 2.

[0030] Specifically, in order to adjust the light output direction of the adjusting bracket 2 and the third lens 33, this embodiment has a slot 100 in the middle of the lens main bracket 1, and the adjusting bracket 2 is inserted into the lens main bracket 1 through the slot 100. Positioning plates 10 are formed on both sides of the lens main bracket 1 near the slot 100, and matching plates 20 are formed on both sides of the adjusting bracket 2. When the adjusting bracket 2 is inserted into the slot 100, the matching plates 20 make limiting contact with the positioning plates 10. Meanwhile, each positioning plate 10 is provided with a shaped limiting post 101, and each positioning plate 20 is provided with a limiting sliding hole 201 that cooperates with the limiting post 101. The limiting post 101 is inserted into the limiting sliding hole 201, which can limit the positioning plate 20 on both sides. In addition, the positioning plate 10 limits the positioning plate 20 longitudinally, allowing the positioning plate 20 to slide only along the direction of the limiting sliding hole 201. That is, the adjusting bracket 2 and the third lens 33 can only slide in the light direction, thus performing the focusing operation.

[0031] In practical application, on the production line, the adjusting bracket 2 is first positioned relative to the lens assembly bracket 1 in the Y and Z directions. Then, focusing in the X direction is performed using on-line tooling, ensuring that the illumination device forms a clear image on the optical display instrument, controlled by gradient according to the design. Simultaneously, a locking hole 202 is provided on the positioning plate 20, containing a countersunk screw 9 suitable for locking the positioning plate 20 and the positioning plate 10. After focusing, the positioning plate 20 and the positioning plate 10 are locked using the countersunk screw 9 to fix the position of the adjusting bracket 2. Once the image is clear, the heat sink assembly is moved in the Y and Z directions while maintaining no movement in the X direction, ensuring that the position of the brightest point of the adaptive high beam center and the near beam cutoff line meets the design requirements. Finally, screws are used for locking to complete the light distribution.

[0032] In the above structure of this embodiment, the lens support 1 and the adjustment bracket 2 are combined and assembled, and the heat sink assembly is assembled with the lens support 1. The first lens 31 and the second lens 32 are installed through the lens support 1, and the third lens 33 is installed through the adjustment bracket 2 and aligned with the first lens 31. This allows for focusing by adjusting the adjustment bracket 2 and the third lens 33 along the light output direction. This structural combination combines the original dual-beam module and the adaptive high beam module into one, simplifying the dimming mechanism between modules while ensuring all functions are maintained. It eliminates traditional fine-tuning parts and achieves a truly integrated design through component design and tooling coordination. Compared with the original multi-structure module, the overall structure of this embodiment reduces the space occupied by the module in the overall lighting environment, occupies less space, simplifies the parts, and lowers the cost, while also possessing the aesthetics and compactness of an integrated design.

[0033] Specifically, the heat sink assembly in this embodiment includes a first heat sink 7, a second heat sink 8, a first assembly plate 70, and a second assembly plate 80. The first heat sink 7 is installed on the rear side of the first assembly plate 70, and the second heat sink 8 is installed on the rear side of the second assembly plate 80. The first light-emitting module is installed on the front side of the first assembly plate 70, and the second light-emitting module is installed on the front side of the second assembly plate 80. The outer peripheries of the first assembly plate 70 and the second assembly plate 80 are assembled with the lens support 1 by screws or adhesive. In this way, the overall structure is integrated, occupying less space, and the first heat sink 7 and the second heat sink 8 can even be made larger to achieve better heat dissipation.

[0034] In addition, the first light-emitting module in this embodiment includes a silicone inner lampshade 51, a first mounting bracket 52, a light-blocking plate 53, and a first PCBA 54 assembled together. The first PCBA 54 and the first mounting bracket 52 are mounted on the front side of the first assembly plate 70, and the silicone inner lampshade 51 and the light-blocking plate 53 are mounted on the first mounting bracket 52. After the optical elements on the first PCBA 54 emit light, it is emitted through the third lens 33 and the first lens 31. The second light-emitting module includes a low beam baffle 61, a second mounting bracket 62, an inner lampshade 63, and a second PCBA 64 assembled together. The second PCBA 64 and the second mounting bracket 62 are mounted on the front side of the second assembly plate 80, and the inner lampshade 63 and the low beam baffle 61 are mounted on the second mounting bracket 62. After the optical elements on the second PCBA 64 emit light, it is emitted through the second lens 32. This embodiment can simultaneously realize the functions of high beam, low beam, and adaptive high beam, and can form a better optical effect on the road surface, completing the splicing of the ADB and the low beam cutoff line, bringing drivers a better and safer night driving experience.
