Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to a vehicle lighting system with a defogging function. Background Technology

[0002] Automotive lights are tools for illuminating roads at night and for issuing various vehicle signals. They are generally divided into headlights, taillights, turn signals, etc., each with different functions and uses, working together to ensure driving safety and improve driving convenience. During driving, the phenomenon of headlight fogging may occur. Fog on the surface of the headlights will affect the light intensity, thereby affecting the driver's vision and posing a high risk. In order to improve this situation, a headlight with a defogging function has been proposed.

[0003] For example, a vehicle light with a defogging function disclosed in the authorization announcement number CN220981097U includes a mounting plate, a mounting box and a bearing. The mounting box is fixedly connected to the upper surface of the mounting plate, the bearing passes through the surface of the mounting box, and a rotating shaft passes through the bearing. A knob is fixedly connected to one end of the rotating shaft, a threaded column is fixedly connected to the other end of the rotating shaft, and a threaded tube is threadedly connected to the other end of the threaded column.

[0004] Although it achieves the goal of setting up a threaded column, threaded tube and fastening ring, when people need to replace the lighting lamp, they only need to turn the knob, which will drive the fastening ring to move under the cooperation of the threaded column and threaded tube, loosening the old lighting lamp, and then replacing it with the new lighting lamp. Turning the knob in the opposite direction will complete the fastening work of the new lighting lamp, which makes it convenient for people to replace lighting lamps, improves people's work efficiency and improves the practicality of the device.

[0005] However, the existing headlights do not solve the problem that they are not conducive to rotating to sweep away fog on the outer wall of the cover and to adjusting the beam angle. They are also not conducive to evenly blowing away fog on the inner wall of the cover and to concentrating the light, which affects the fog removal effect and the light illumination effect. Utility Model Content

[0006] The purpose of this utility model is to provide a vehicle light with a defogging function, so as to solve the problems mentioned in the background art, which are that the vehicle light is not easy to rotate to scrape the fog on the outer wall of the outer cover and to adjust the beam angle, which is not conducive to the uniform blowing of air to remove fog on the inner wall of the outer cover and to the concentrated illumination of light, thus affecting the defogging effect and the light illumination effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vehicle light with a defogging function, comprising a rear shell and a transparent outer cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the vehicle light not only realizes the convenient rotation to scrape the fog on the outer wall of the cover and the rotation to adjust the beam angle, but also facilitates the even blowing of air to remove fog on the inner wall of the cover and the concentrated illumination of light, and improves the fog removal effect and the light illumination effect.

[0016] (1) The first motor drives the first gear to reciprocate through the first movable shaft. The first gear drives the arc rack to reciprocate.

It realizes convenient rotation and scraping of fog on the outer wall of the cover, and facilitates the uniform air blowing and fog removal of fog on the inner wall of the cover in a circular motion, thus improving the fog removal effect.

[0017] (2) The adjusting motor drives the fixed ring to rotate through the linkage shaft, and the fixed ring drives the rotating plate and the bulb to rotate, so as to vertically rotate and adjust the illumination position of the bulb. The flipping motor drives the rotating plate and the bulb to rotate through the hinge shaft, so as to horizontally rotate and adjust the illumination position of the bulb. If the illumination light of the bulb is relatively diffuse, the servo motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the two sets of bidirectional threaded sleeves to move towards each other. The bidirectional threaded sleeves drive the bulbs to move closer to each other, so as to adjust the concentration of the light, thereby improving the illumination effect. This realizes convenient rotation adjustment of the light illumination angle, facilitates the concentrated illumination of the light, and improves the illumination effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 This utility model provides an embodiment of a vehicle headlight with a defogging function, comprising a rear shell 5 and a transparent outer cover 1. The transparent outer cover 1 is installed on the side wall of the rear shell 5. A fixing ring 10 is provided inside the transparent outer cover 1. A movable gear ring 18 is slidably installed on the surface of the fixing ring 10. A bearing block 26 is installed on the inner wall of the fixing ring 10. A second motor 16 is installed on the side wall of the bearing block 26, and the second motor 16 provides power drive. A second movable shaft 15 is installed at the output end of the second motor 16. A second gear 17 is fitted on the surface of the second movable shaft 15, and the second gear 17 meshes with the movable gear ring 18. Multiple sets of fans 19 with equal spacing are installed on the side wall of 8. A first motor 6 is symmetrically installed on the outer wall of the transparent cover 1. The first motor 6 plays the role of power drive. A first movable shaft 23 is installed at the output end of the first motor 6. A first gear 4 is fitted on the surface of the first movable shaft 23. A rotating shaft 7 is movably installed on the side wall of the transparent cover 1 on one side of the first motor 6. An arc-shaped rack 3 is installed on the surface of the rotating shaft 7 on one side of the first gear 4. The first gear 4 and the arc-shaped rack 3 mesh with each other. A scraping strip 2 is provided on the outside of the transparent cover 1. The scraping strip 2 is fixedly connected to the rotating shaft 7 and slidably connected to the transparent cover 1.

[0026] The headlight is mounted to the vehicle via mounting feet 25. When fog forms on the outer wall of the transparent cover 1, the first motor 6 is activated. The first motor 6 drives the first gear 4 to reciprocate through the first movable shaft 23. Under the meshing of the first gear 4 and the arc-shaped rack 3, the first gear 4 drives the arc-shaped rack 3 to reciprocate. The arc-shaped rack 3 drives the scraper 2 to slide back and forth on the surface of the transparent cover 1 through the rotating shaft 7. The scraper 2 scrapes and cleans the fog on the outer wall of the transparent cover 1. The fan 19 is activated to blow air and defog the fog on the inner wall of the transparent cover 1. The vent 24 provides ventilation. When the second motor 16 is turned on, the second motor 16 drives the second gear 17 to rotate through the second movable shaft 15. Under the mutual meshing of the second gear 17 and the movable gear ring 18, and under the limiting movement cooperation between the movable gear ring 18 and the fixed ring 10, the second gear 17 drives the movable gear ring 18 to rotate, and the movable gear ring 18 drives the fan 19 to rotate. The fan 19 performs circumferential rotation to blow air and remove fog from the inner wall of the transparent outer cover 1, thereby increasing the uniformity of air blowing and fog removal. This achieves convenient rotation and scraping of fog on the outer wall of the outer cover, and facilitates circumferential rotation and uniform air blowing and fog removal of fog on the inner wall of the outer cover, thus improving the fog removal effect.

[0027] The surface of the rear cover 5 is equipped with multiple sets of ventilation holes 24, and the bottom of the rear cover 5 is equipped with two sets of mounting feet 25.

[0028] A linkage shaft 9 is symmetrically installed on the outer wall of the fixed ring 10, and an adjustment motor 8 is installed on the inner wall of the transparent outer cover 1 on one side of a set of linkage shafts 9. The adjustment motor 8 plays the role of power drive. The output end of the adjustment motor 8 is connected to the set of linkage shafts 9, and the other set of linkage shafts 9 is movably connected to the transparent outer cover 1.

[0029] The fixed ring 10 has a rotating plate 13 inside. Both ends of the rotating plate 13 are equipped with hinge shafts 12. The rotating plate 13 is movably connected to the fixed ring 10 through the hinge shafts 12. A flip motor 11 is installed on the outer wall of the fixed ring 10 on one side of the hinge shaft 12. The flip motor 11 plays the role of power drive, and the output end of the flip motor 11 is connected to the hinge shaft 12.

[0030] A servo motor 22 is installed inside the rotating plate 13. The servo motor 22 serves as a power drive. A bidirectional threaded rod 21 is installed at the output end of the servo motor 22. The bidirectional threaded rod 21 is movably connected to the rotating plate 13. Two sets of bidirectional threaded sleeves 20 are fitted on the surface of the bidirectional threaded rod 21. The bidirectional threaded sleeves 20 are threadedly connected to the bidirectional threaded rod 21. The bidirectional threaded sleeves 20 are slidably connected to the rotating plate 13. A bulb 14 is installed on the side wall of each bidirectional threaded sleeve 20.

[0031] Turn on the adjustment motor 8, which drives the fixed ring 10 to rotate via the linkage shaft 9. The fixed ring 10 then drives the rotating plate 13 and the bulb 14 to rotate, thus vertically adjusting the illumination position of the bulb 14. Turn on the flip motor 11, which drives the rotating plate 13 and the bulb 14 to rotate via the hinge shaft 12, thus horizontally adjusting the illumination position of the bulb 14. If the illumination light from the bulb 14 is too diffuse, turn on the servo motor 22, which drives the bidirectional threaded rod 21 to rotate. With the bidirectional threaded rod 21 and the bidirectional threaded sleeve 20 threaded together, the bidirectional threaded rod 21 drives the two sets of bidirectional threaded sleeves 20 to move towards each other. The bidirectional threaded sleeves 20 then drive the bulb 14 to move closer together, thus adjusting the concentration of the light and improving the illumination effect. This allows for convenient rotation and adjustment of the light illumination angle, facilitating concentrated illumination and improving the overall illumination effect.

[0032] Working principle: The headlight is mounted on the vehicle via mounting feet 25. When fog forms on the outer wall of the transparent cover 1, the first motor 6 drives the first gear 4 to reciprocate via the first movable shaft 23. The first gear 4 drives the arc rack 3 to reciprocate, and the arc rack 3 drives the scraper 2 to slide back and forth on the surface of the transparent cover 1 via the rotating shaft 7. The scraper 2 scrapes and cleans the fog on the outer wall of the transparent cover 1. The fan 19 blows air to defog the fog on the inner wall of the transparent cover 1. The vent 24 provides ventilation. The second motor 16 drives the second gear 17 to rotate via the second movable shaft 15. The second gear 17 drives the movable gear ring 18 to rotate, and the movable gear ring 18 drives the fan 19 to rotate. The fan 19 then blows air onto the transparent cover. The inner wall of the lamp 1 rotates in a circular motion to blow air and defog, thereby increasing the uniformity of the defogging process. The adjusting motor 8 drives the fixed ring 10 to rotate via the linkage shaft 9. The fixed ring 10 drives the rotating plate 13 and the bulb 14 to rotate, thereby vertically adjusting the illumination position of the bulb 14. The flipping motor 11 drives the rotating plate 13 and the bulb 14 to rotate via the hinge shaft 12, thereby horizontally adjusting the illumination position of the bulb 14. If the illumination light from the bulb 14 is too diffuse, the servo motor 22 drives the bidirectional threaded rod 21 to rotate. The bidirectional threaded rod 21 drives the two sets of bidirectional threaded sleeves 20 to move towards each other. The bidirectional threaded sleeves 20 drive the bulb 14 to move closer to each other, thereby adjusting the concentration of the light and improving the illumination effect, thus completing the use of the vehicle light with defogging function.
