[0024] A dimming device for an automotive lamp includes a housing 1 and a lamp cover 2. An adjustment assembly 3 is connected to one side of the housing 1. The adjustment assembly 3 includes a bearing seat 301, a lead screw 302 connected to the inner ring of the bearing seat 301, a geared motor 303 connected to one end of the lead screw 302, and a mounting bracket 304 threaded onto the outer surface of the lead screw 302. A mounting base 305 is hinged to one side of the mounting bracket 304 via a first pin. A lamp holder 306 is mounted on one side of the mounting base 305. A connecting plate 307 is connected to one side of the mounting base 305. An electric push rod 308 is hinged to one side of the connecting plate 307 via a second pin. One end of the electric push rod 308 is connected to the inner ring of the mounting bracket 304 via a third pin. The side walls are hinged together, and a reflector plate 309 is connected to one side of the lamp cover 2. The rotation of the geared motor 303 can drive the lead screw 302 to rotate in the inner ring of the bearing seat 301. The lead screw 302 is threadedly connected to the mounting bracket 304, which can drive the lamp head 306 to move left or right. At the same time, in conjunction with the lamp cover 2, it can magnify or reduce the light beam and fine-tune its brightness. Through the pushing force of the electric push rod 308, and in conjunction with the use of the first pin, second pin, third pin and connecting plate 307, it can adjust the beam of the lamp head 306 up and down. In addition, in conjunction with the use of the reflector plate 309, it can improve the brightness of the beam and increase driving safety.
[0025] In this embodiment, two sets of heat dissipation holes 9 are provided on the inner sidewall of the outer casing 1. Each heat dissipation hole 9 is connected to a dustproof mesh 10 on its inner sidewall. The heat dissipation holes 9 and the dustproof mesh 10 can facilitate heat dissipation of the electrical components inside the outer casing 1 and isolate external dust. A power connector 4 is connected to one side of the outer casing 1, and a power connector 5 is connected to one side of the power connector 4. The power connector 4 and the power connector 5 can facilitate power connection to the device. At the same time, the electrical components inside the outer casing 1 need to be connected to power through wires. A cover plate 11 is provided on one side of the outer casing 1. A set of mounting screw holes 12 is provided on one side of the outer casing 1 and a set of mounting screws 13 is provided on the top of the cover plate 11. Each mounting screw 13 is adapted to the mounting screw hole 12. The cover plate 11, mounting screw holes 12 and mounting screws 13 can be used to facilitate the maintenance of electrical components inside the outer casing 1 and to facilitate sealing. A sliding rod 14 is connected to the inner wall of the outer casing 1. The inner wall of the mounting bracket 304 is slidably connected to the outer surface of the sliding rod 14. The sliding rod 14 can improve the stability of the mounting bracket 304 and prevent it from swinging or misaligning.
[0026] In this embodiment, a mounting plate 7 is connected to one side of the mounting bracket 304, and a cooling fan 8 is installed on one side of the mounting plate 7. The mounting plate 7 and the cooling fan 8 can be used to easily dissipate heat from the electrical components inside the housing 1 through physical means. A reinforcing block 6 is connected to one side of the geared motor 303, and one side of the reinforcing block 6 is connected to one side of the housing 1. The reinforcing block 6 can increase the stability of the geared motor 303 and prevent it from loosening and cracking. The outer surface of the geared motor 303 is connected to one side of the housing 1. The lampshade 2 is made of tempered glass, which can improve the quality of the lampshade 2.
[0027] Working principle: First, the electrical components inside the housing 1 are inspected using the mounting screw holes 12, mounting screws 13, and cover plate 11 as needed. The electrical components are then connected to their internal components via wires. During use, the power connector 4 and power terminal 5 are installed at the headlight mounting position. Simultaneously, the device's program is connected to the vehicle's control program. If the beam needs to be adjusted vertically, the electric push rod 308 is activated. The pushing force of the electric push rod 308, in conjunction with the first, second, and third pins, allows for adjustment of the angle between the mounting base 305 and the lamp head 306. The use of the refractive plate 309 allows for adjustment of the beam height and intensity. When beam size adjustment is needed, the geared motor 303 is activated. The rotation of the geared motor 303 causes the lead screw 302 to rotate within the bearing housing 301. This, combined with the threaded connection between the lead screw 302 and the mounting bracket 304, and the sliding connection between the mounting bracket 304 and the slide rod 14, allows the mounting base 305 and the lamp head 306 to move left and right. This, along with the lampshade 2, allows for beam size adjustment and increased brightness. The above describes the complete usage process of this utility model.
[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
