[0002] Vehicle lights are tools for illuminating roads when vehicles are driving at night, and also for issuing various vehicle driving signals. In order to adapt to different usage environments, vehicle lights need to be adjusted using a dimming device.

[0003] In related technologies, a vehicle headlight dimming device uses a motor to drive a swing arm to rotate up or down. A guide rod moves within the long slot of the swing arm as the swing arm rotates, and drives a connecting rod to move up or down. A reflector rotates around one end of the reflector via a hinge under the action of the connecting rod, forming different tilt angles. By adjusting the angle of the reflector, the light emitted by the lamp source is reflected to different positions, thereby adjusting the angle of light illumination.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0029] Example:

[0030] This utility model provides a technical solution: a vehicle headlight dimming device, including a housing 1, as shown in the figure. Figure 1A base 2 is provided on one side of the housing 1, and an LED light source 3 is provided on the side of the base 2 inside the housing 1; a first annular frame 8 is connected to the inner wall of the housing 1, and multiple rotatable trapezoidal reflectors 11 are provided on the side of the first annular frame 8 away from the base 2. The multiple reflectors 11 cooperate with each other, and a movable second annular frame 14 is provided on the side of the first annular frame 8 away from the base 2. The multiple reflectors 11 are all located in the second annular frame 14; the reflectors 11 are used to adjust the light emitted by the LED; a detachable transparent cover 5 is provided on the other side of the housing 1.

[0031] Specifically, such as Figure 4 The first annular frame 8 has multiple rotating slots 9 on the side near the reflector 11, each slot 9 corresponding to a different reflector 11. These slots 9 are evenly distributed on the first annular frame 8. Each slot 9 contains a rotating block 10, and each reflector 11 is connected to one side of a rotating block 10. Each reflector 11 has a first connecting seat 12 connected to one side, and each first connecting seat 12 has a push rod 13 rotatably connected to it. The second annular frame 14 has multiple second connecting seats 15 on the side away from the first annular frame 8. The other ends of the push rods 13 are rotatably connected to the second connecting seats 15. The second annular frame 14 has two fixing sleeves 16 connected to it. Figure 3 Two sliding grooves 17 are formed on one side of the housing 1, and two fixing sleeves 16 are slidably connected in the two sliding grooves 17 respectively. A protective shell 19 is connected to one side of the housing 1. The other sides of the two fixing sleeves 16 pass through the sliding grooves 17 and are connected to a sliding frame 18. The sliding frame 18 is slidably connected in the protective shell 19. A support frame 20 is connected to one side of the protective shell 19. A motor 21 is connected to the support frame 20. The output shaft of the motor 21 is connected to a rotating shaft 22. The other end of the rotating shaft 22 passes through the protective shell 19 and is located in the protective shell 19. A first rotating rod 23 is connected to the rotating shaft 22. A second rotating rod 24 is rotatably connected to the first rotating rod 23. The other end of the second rotating rod 24 is rotatably connected to one side of the sliding frame 18. A concave mounting seat 4 is connected to one side of the housing 1. Figure 2 The transparent cover 5 is connected to the mounting base 4. A fixing plate 6 is connected to the upper part of the transparent cover 5, and fixing bolts 7 are provided on the fixing plate 6. The transparent cover 5 is connected to the mounting base 4 by fixing bolts 7. By adopting the above technical solution, the second ring frame 14 can be moved synchronously away from or closer to the first ring frame 8 by the push rod 13, fixing sleeve 16, sliding groove 17 and sliding frame 18, so as to cooperate in use. The sliding frame 18 can be moved back and forth in the protective shell 19 by the motor 21, rotating shaft 22, first rotating rod 23 and second rotating rod 24, so as to drive the internal reflector 11 to reciprocate and adjust. The mounting base 4, fixing plate 6 and fixing bolts 7 make it convenient to clean and replace the transparent cover 5 after a period of use.

[0032] The working principle of this utility model is as follows: During use, the operator can place the housing 1 in the designated location on the vehicle body. The housing 1 is then installed by connecting and fixing it to the base 2. Power is supplied to the LED light source 3, causing it to emit light that illuminates the transparent cover 5. Depending on the application requirements, power can be supplied to the motor 21, which in turn drives the rotating shaft 22 to rotate. This rotation of the shaft 22 causes the first rotating rod 23 to rotate around the shaft 22. As the first rotating rod 23 rotates, it drives the second pushing rod 13 to pull the sliding frame 18. As the sliding frame 18 moves, it... The two fixed sleeves 16 slide within the two sliding grooves 17. When the two fixed sleeves 16 drive the second annular frame 14 located within the housing 1 to move synchronously away from the first annular frame 8, the second annular frame 14 moves, driving the push rod 13 to push the reflector 11. The two ends of the push rod 13 rotate on the first connecting seat 12 and the second connecting seat 15 respectively, allowing the push rod 13 on one side of the second annular frame 14 to smoothly push the reflector 11 as the second annular frame 14 moves away from the first annular frame 8. After being pushed by the push rod 13, the reflector 11 moves through the rotating block 10, moving away from the first annular frame 8. The frame 8 rotates, and due to the specially shaped second annular frame 14, when the second annular frame 14 moves, the push rod 13 on the second annular frame 14 simultaneously pushes multiple reflectors 11, causing the multiple reflectors 11 to converge synchronously until they contact each other, reaching the maximum adjustment value. At this time, the light focusing effect of the reflectors 11 is optimal. When it is necessary to reduce the light focusing effect, the motor 21 rotates in the opposite direction, causing the first rotating rod 23 to rotate in the opposite direction around the rotating shaft 22, which in turn drives the second push rod 13 to push the sliding frame 18, causing the sliding frame 18 to slide in the opposite direction. With the cooperation of the fixing sleeve 16, the second ring frame 14 is pulled closer to the first ring frame 8, thereby pulling the reflector 11 through multiple push rods 13. The multiple reflectors 11 are pulled to rotate on the first ring frame 8. The multiple reflectors 11 rotate and disperse, thereby adjusting the reflection angle of light, which is convenient for the staff to operate and use. After a period of use, dust and scratches are easily generated on the transparent cover 5 set on one side of the housing 1, which will cause the light transmittance of the transparent cover 5 itself to deteriorate and affect the light effect. The staff can remove the fixing bolts 7 to remove the transparent cover 5 from the mounting base 4, thereby replacing or cleaning the transparent cover 5.

[0033] 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.
