[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example: A focal length adjustable automotive headlight module external lens bracket, such as... Figure 1 and Figure 2 As shown, the device includes a headlight bracket 1, with a lens mounting groove 2 at one end and a light source assembly block 3 at the end of the headlight bracket 1 away from the lens mounting cylinder 7. In the middle of the headlight bracket 1, there are LED lamp bead board slots 4, light blocking plates 5, and reflector slots 6. The installer and user can fix the headlight bracket 1 to the vehicle body to achieve the lighting of the headlight source.

[0017] A lens mounting cylinder 7 is movably connected within the lens mounting slot 2, and a lens block 8 is fixed inside the lens mounting cylinder 7. This allows for adjustment of the lens position to change the working focal length of the light source, achieving focused and efficient lighting. Simultaneously, in cases where strong sunlight during the day might focus through the lens and damage the lampshade, the lens mounting cylinder 7 can be flexibly retracted into the lens mounting slot 2 to provide light-shielding protection. Once normal lighting is required, the lens mounting cylinder 7 can flexibly and quickly return to its initial position.

[0018] The lens mounting cylinder 7 has a locking thread section 9 on its outer wall, and the lens mounting groove 2 has an internal thread section 10 that locks into the locking thread section 9 on its inner wall. The assembly and appropriate position adjustment of the lens mounting cylinder 7 are achieved by means of the threaded engagement. The bottom of the lens mounting groove 2 is also provided with a stepped groove block 11, which has multiple adjusting arc grooves 12. At the same time, multiple adjusting lugs 13 are movably inserted into the lens mounting cylinder 7. The adjusting lugs 13 are respectively inserted into the adjusting arc grooves 12. In actual assembly and use, the user first completes the screw engagement between the lens mounting cylinder 7 and the lens mounting groove 2, and then inserts the adjusting lugs 13 into the adjusting arc grooves 12 to fix them to the lens mounting cylinder 7, so that the adjusting lugs 13 can slide in the adjusting arc grooves 12.

[0019] An auxiliary ring edge 14 is provided at the end of the adjusting lug 13 away from its connection with the lens mounting cylinder 7, and a mounting slot 15 is provided on the auxiliary ring edge 14. A drive support plate 16 passes through the mounting slot 15, and the rotation adjustment of the adjusting lug 13 and the lens mounting cylinder 7 is driven by the drive support plate 16. A limiting ring block 17 is provided at the end of the drive support plate 16 near the adjusting lug 13, and an auxiliary locking ring block 18 is provided between the limiting ring block 17 and the adjusting lug 13. The auxiliary locking ring block 18 is slidably inserted into the drive support plate 16, and can slide between the limiting ring block 17 and the auxiliary ring edge 14. An elastic reset component is provided between the auxiliary locking ring block 18 and the limiting ring block 17. The elastic reset component includes an elastic groove 27 between the auxiliary locking ring block 18 and the limiting ring block 17. A reset spring 28 is provided in the elastic groove 27. Under normal conditions, the auxiliary locking ring block 18 and the auxiliary ring edge 14 are always kept in contact under the elastic compression of the reset spring 28. This can improve the position of the adjustment ear block 13 relative to the drive support plate 16 under normal working conditions, thereby reducing the abnormal lighting status of the headlights that may be caused by its free movement. At the same time, it can also effectively absorb and buffer the vibration of the headlight lens during vehicle movement.

[0020] To achieve stable adjustment of the drive support plate 16, a drive slot 19 is provided on the light source assembly block 3 for the drive support plate 16 to pass through. The end of the drive support plate 16 passes through the drive slot 19, and the width of the drive slot 19 is greater than the width of the drive support plate 16. At the same time, an adjusting sleeve 20 is rotatably connected to the side of the light source assembly block 3 away from the lens mounting slot 2. The end of the drive support plate 16 away from the auxiliary ring edge 14 is inserted and fixed to the adjusting sleeve 20. That is, the rotation of the adjusting sleeve 20 can drive the drive support plate 16 to rotate, thereby driving the lens mounting cylinder 7 to rotate and extend. The slot width of the drive slot 19 also ensures that the lens mounting cylinder 7 can only be extended and extended within a certain appropriate range, ensuring the stable and reliable operation of the entire vehicle lighting equipment.

[0021] Considering the need for a structured and compact layout design of the vehicle lighting module, the adjusting sleeve 20 has an adjusting drive cavity 21 inside. This cavity contains a light source insertion slot 22 fixed to the light source assembly block 3, allowing installers to assemble and fix the light source module, achieving communication with the LED bead board slot 4. The light source insertion slot 22 has a mounting groove 23, within which an adjusting motor 24 is installed. The inner wall of the adjusting sleeve 20 has an adjusting toothed belt 25, and the adjusting motor 24 has a transmission toothed block 26 that meshes with the adjusting toothed belt 25. The operation of the adjusting motor 24 drives the adjusting sleeve 20 to rotate, ultimately driving the rotation of the drive plate 16, which in turn drives the rotation and extension / retraction adjustment of the lens mounting cylinder 7. To further improve the stability and flexible response of lens position adjustment and holding, multiple adjusting motors 24 and mounting grooves 23 are symmetrically arranged about the light source insertion slot 22 in the bracket, achieving a stable state of synchronous multi-motor drive.

[0022] Because the light source module generates a large amount of heat during prolonged operation, timely heat dissipation is necessary. The slot of the light source insertion slot 22 is equipped with a protective ring edge 29 to ensure a close fit with the adjusting sleeve 20. Simultaneously, a heat sink mounting hole 30 is provided on the protective ring edge 29, facilitating the installation and fixation of the lamp's heat sink by the user. Furthermore, multiple heat-conducting grooves 31 are provided on the side wall of the light source insertion slot 22, enabling efficient heat dissipation from the middle of the headlight bracket 1. Additionally, heat-conducting sheets are provided on the inner wall of the drive support plate 16, enabling the transfer and dissipation of heat from the working part of the lens at the end of the headlight bracket 1 to the heat sink, improving the efficiency and stability of the overall internal heat dissipation channel system of the lamp.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
