Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a heat dissipation bracket for an automotive LED module, comprising an LED body 1 and a sleeve 2. Heat dissipation fins 3 are provided on the outer side of the sleeve 2. Two connecting rods 4 are fixed to the outer side of the heat dissipation fins 3, and a connecting plate 5 is fixed between the two connecting rods 4. Multiple connecting holes 6 are provided on the top surface of the connecting plate 5. A telescopic cylinder 7 is fixed to the bottom surface of the sleeve 2. A spring 8 is fixed to the bottom inner side of the telescopic cylinder 7, and the top surface of the spring 8 is fixedly connected to the top inner side of the telescopic cylinder 7. A movable rod 10 is fixed to the bottom surface of the telescopic cylinder 7. A threaded protrusion 11 is provided on the outer side of the movable rod 10. A movable ring 12 is slidably connected to the outer side of the movable rod 10. A threaded groove 18 is provided on the inner side of the movable ring 12, and a connecting groove 13 is provided on the outer side of the movable ring 12. The inner side of the connecting groove 13 is rotatably connected to... A connecting ring 14 is attached, and two fixing rods 15 are fixed to the outer circumference of the connecting ring 14. The lower end of the fixing rods 15 is fixedly connected to the top surface of the connecting plate 5. Two scrapers 16 are fixed to the outer side of the movable ring 12. Multiple grooves 9 are opened on the outer side of the scrapers 16. A stabilizing ring 17 is rotatably connected to the top of the outer side of the sleeve 2. The outer circumference of the stabilizing ring 17 is fixedly connected to the upper end of the scraper 16. The LED body 1 is located inside the sleeve 2. The heat dissipation fins 3 include multiple annular pieces, which are arranged at equal intervals. The telescopic cylinder 7 is made of copper and is filled with a mixture of paraffin wax and copper powder. The center of the movable rod 10 is on the same straight line as the center of the sleeve 2. The inner side of the threaded groove 18 is slidably connected to the outer side of the threaded protrusion 11. The inner side of the groove 9 is slidably contacted with the outer side of the heat dissipation fins 3.

[0023] The heat generated by the LED body 1 is transferred to the heat dissipation fins 3 through the sleeve 2, and then transferred to the air through heat exchange between the heat dissipation fins 3 and the air. During this process, some heat is transferred to the telescopic cylinder 7 through the sleeve 2, thereby heating the paraffin and copper powder mixture in the telescopic cylinder 7. Due to the thermal conductivity of the copper powder, the paraffin is uniformly heated and expands in volume, thus pushing the movable rod 10 downward. During this process, the threaded protrusion 11 on the movable rod 10 slides against the threaded groove 18 on the movable ring 12, thereby causing the movable ring 12 to rotate along the outside of the movable rod 10. The movable ring 12 is confined in the connecting ring 14. The movable ring 12 drives the two scrapers 16 to rotate, and the grooves 9 on the scrapers 16 slide along the outside of the heat dissipation fins 3. The dust on the heat sink fins 3 is scraped off. During the movement of the scraper 16, the scraper 16 moves in coordination with the stabilizing ring 17 to maintain the stability of the scraper 16. When the LED body 1 stops working, the volume of the paraffin and copper powder mixture shrinks. Under the pull of the spring 8, the telescopic cylinder 7 drives the movable rod 10 to move upward and return to its original position, causing the movable ring 12 to move back. The movable ring 12 drives the scraper 16 to rotate back and return to its original position. Through the above process, the heat sink fins 3 can be automatically cleaned, keeping the heat sink fins 3 clean. This solves the problem that dust in the automotive working environment is abundant and easily adheres to the heat sink bracket, making it difficult for the heat sink bracket to contact the air, thus affecting the heat dissipation efficiency. Manual cleaning requires disassembling the car lights, which is time-consuming and laborious.

[0024] The specific usage and function of this embodiment: The heat generated by the LED body 1 of this utility model is transferred to the heat dissipation fins 3 through the sleeve 2. The heat is then transferred to the air through heat exchange between the heat dissipation fins 3 and the air. During this process, some heat is transferred to the telescopic cylinder 7 through the sleeve 2, thereby heating the paraffin wax and copper powder mixture in the telescopic cylinder 7. Due to the thermal conductivity of the copper powder, the paraffin wax is uniformly heated and expands in volume, thus pushing the movable rod 10 downwards. During this process, the threaded protrusion 11 on the movable rod 10 slides against the threaded groove 18 on the movable ring 12, thereby driving the movable ring 12 along the movable rod. The outer side of the 10 rotates, and the movable ring 12 is restricted in the connecting ring 14. The movable ring 12 drives the two scrapers 16 to rotate. The groove 9 on the scraper 16 slides along the outer side of the heat sink 3, thereby scraping off the dust on the heat sink 3. During the movement of the scraper 16, the scraper 16 moves in coordination with the stabilizing ring 17 to keep the scraper 16 stable. When the LED body 1 stops working, the volume of the paraffin and copper powder mixture shrinks. Under the pull of the spring 8, the telescopic cylinder 7 drives the movable rod 10 to move upward and return to its original position, so that the movable ring 12 moves back. The movable ring 12 drives the scraper 16 to rotate back and return to its original position.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
