[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figures 1-3 This utility model provides an embodiment of an automotive lamp with an automatic defogging function, comprising a back plate 1, a motor 2 fixedly connected to the outer wall of the back plate 1, a connecting post 3 fixedly provided at the output end of the motor 2, the outer wall of the connecting post 3 being rotatably connected to the inner wall of the back plate 1, a sprocket 4 fixedly connected to the outer wall of the connecting post 3, a chain 5 meshing with the toothed end of the sprocket 4, a fixing block 6 fixedly connected to the outer wall of the chain 5, a sliding frame 7 slidably connected to the outer wall of the fixing block 6, a sliding plate 8 fixedly connected to the outer wall of the sliding frame 7, a scraper 9 fixedly connected to the upper surface of the sliding plate 8, and a protective component provided on the outer wall of the scraper 9 for protecting the lamp; the protective component includes a transparent shell 10, the outer wall of the scraper 9 being slidably connected to the outer wall of the transparent shell 10, an outer shell 11 fixedly connected to the outer wall of the transparent shell 10, the outer wall of the sliding plate 8 being slidably connected to the inner wall of the outer shell 11, and the outer wall of the back plate 1 being fixedly connected to the inner wall of the outer shell 11;
[0026] Specifically, the back plate 1 can provide fixed support for the motor 2. When the motor 2 is turned on, the motor 2 will drive the connecting column 3 to rotate, and the rotation of the connecting column 3 will drive the sprocket 4 to rotate. The rotation of the sprocket 4 will also drive the chain 5 to slide. At the same time, the sliding of the chain 5 will drive the fixing block 6 to slide. The sliding of the fixing block 6 will slide on the inner wall of the sliding frame 7. When the fixing block 6 slides on the inner wall of the sliding frame 7, it will also drive the sliding frame 7 to slide parallel. At the same time, the sliding of the sliding frame 7 will drive the sliding plate 8 to slide on the inner wall of the outer shell 11. The sliding of the sliding plate 8 will drive the scraper 9 to reciprocate on the outer wall of the transparent shell 10. Through the reciprocating motion of the transparent shell 10, water droplets, fog or frost on the inner surface of the lamp can be directly removed, ensuring that the surface of the lamp is always clean and does not affect the lighting effect.
[0027] Reference Figure 4A sliding box 12 is slidably connected to the inner wall of the back panel 1, and a handle 13 is fixedly connected to the outer wall of the sliding box 12; a slide rail 14 is slidably connected to the inner wall of the sliding box 12, and a fixed frame 15 is fixedly connected to the lower surface of the slide rail 14; the outer wall of the fixed frame 15 is fixedly connected to the outer wall of the back panel 1.
[0028] Specifically, the back plate 1 can support the sliding box 12, and the sliding box 12 can also provide fixed support for the handle 13. The handle 13 can facilitate the sliding of the sliding box 12. The sliding box 12 contains a desiccant, which can absorb moisture inside the lamp and reduce the formation of water droplets and fog. The slide rail 14 can stabilize the sliding box 12, ensuring its stability during sliding. The fixing frame 15 can also provide fixed support for the slide rail 14, and the back plate 1 can also provide fixed support for the fixing frame 15.
[0029] Reference Figure 5 A T-shaped plate 16 is slidably connected to the inner wall of the back plate 1, and a spring 17 is fixedly connected to the T-shaped plate 16; a hollow frame 18 is fixedly connected to the outer wall of the spring 17, and the outer wall of the T-shaped plate 16 is slidably connected to the inner wall of the hollow frame 18; a fixing post 19 is fixedly connected to the upper surface of the T-shaped plate 16, and the outer wall of the fixing post 19 is slidably connected to the inner wall of the hollow frame 18; a locking block 20 is fixedly connected to the upper surface of the fixing post 19, and the outer wall of the locking block 20 is set on the inner wall of the sliding box 12.
[0030] Specifically, the back plate 1 supports the T-shaped plate 16. When the T-shaped plate 16 is pulled, it causes the fixing post 19 to slide against the inner wall of the hollow frame 18. The sliding of the fixing post 19, in turn, causes the locking block 20 to slide. When the locking block 20 slides out of the inner wall of the sliding box 12, the limiting position on the sliding box 12 is released, allowing the sliding box 12 to be pulled out through the handle 13 for easy and quick replacement of the desiccant inside the sliding box 12. When it is necessary to fix the sliding box 12 to the inner wall of the back plate 1... When the wall is closed, the sliding box 12 is slid to the inner wall of the back plate 1. The spring force of the spring 17 drives the T-shaped plate 16 to slide. The sliding of the T-shaped plate 16 will drive the fixed column 19 and the locking block 20 to slide, so that the locking block 20 slides to the inner wall of the sliding box 12, locking the sliding box 12 and limiting the sliding box 12. By using the desiccant inside the sliding box 12 and quickly replacing the desiccant inside the sliding box 12, the internal environment of the lamp is kept dry, reducing the formation of water droplets and fog, and maintaining the stability of the lamp's lighting.
[0031] Working principle: When using this device, the operator first turns on motor 2, causing the connecting column 3 to rotate. The rotation of connecting column 3 then drives sprocket 4 to rotate, which in turn causes chain 5 to slide. The sliding of chain 5 causes fixed block 6 to slide, which in turn causes sliding frame 7 to slide. The sliding of sliding frame 7 then causes sliding plate 8 to slide, which in turn causes scraper 9 to reciprocate against the outer wall of transparent shell 10, achieving the effect of cleaning the lamp by removing water mist. Then, the operator can push T-shaped plate 16, causing fixed column 19 to slide. The sliding of the fixed column 19 will cause the locking block 20 to slide. When the locking block 20 slides out of the inner wall of the sliding box 12, the handle 13 is pulled. The handle 13 drives the sliding box 12 to slide on the outer wall of the slide rail 14, so as to quickly open the sliding box 12 and replace the desiccant inside the sliding box 12. The desiccant prevents the formation of water mist. That is, this device can not only clean the lamps that have formed fog by reciprocating sliding scraper 9 to prevent fog from affecting the lighting effect of the lamps and causing traffic safety hazards, but also quickly add and replace the desiccant inside the sliding box 12 to ensure that the lamps are kept in a dry environment, reduce the formation of water droplets and fog, and maintain the stability of the lamp lighting.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
