[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Reference Figure 1-6 As shown, the automobile headlight with adjustable visual area includes a mounting plate 1 with a semicircular structure, an LED headlight 2 is rotatably mounted on the mounting plate 1, and a driving assembly for driving the LED headlight 2 to rotate back and forth horizontally on the mounting plate 1. The mounting plate 1 is welded to the interior of the headlight housing, and the rear end surface of the bottom of the LED headlight 2 is rotatably connected to the mounting plate 1. The driving assembly includes a rotating shaft 501 arranged at the rear end of the bottom of the LED headlight 2, a conical driven gear 502 sleeved on the rotating shaft 501, a support end 503 arranged at the rear end of the upper surface of the mounting plate 1, a driving motor 504 arranged on the support end 503, and a driving motor 504 arranged on the driving shaft. The conical driving gear 505 at the driving end of the motor 504 is engaged with the conical driven gear 502. The conical driving gear 505 is located behind the LED headlight 2. The driving motor 504 drives the conical driving gear 505 to rotate. Since the conical driving gear 505 is engaged with the conical driven gear 502, and the conical driven gear 502 is sleeved on the rotating shaft 501, the rotating shaft 501 and the LED headlight 2 are driven to rotate horizontally back and forth on the mounting plate 1 to adjust the horizontal illumination angle of the LED headlight 2. The illumination angle is adjusted according to the driver's turning needs to change the visible area.

[0021] A guide rail 3 with an arc-shaped structure is provided at the front end of the upper surface of the mounting plate 1, and the guide rail 3 is arranged concentrically with the mounting plate 1. A roller assembly 4 that is transmission-connected to the guide rail 3 is provided on the front end surface of the bottom of the LED headlight 2. The roller assembly 4 includes a base 401 arranged on the front end surface of the bottom of the LED headlight 2, a first connecting plate 402 rotatably arranged on one side of the bottom of the base 401, a second connecting plate 403 rotatably arranged on the other side of the bottom of the base 401, and four rollers 404 symmetrically arranged on the first connecting plate 402 and the second connecting plate 403, and the first connecting plate 402 and the second connecting plate 403 are arranged at intervals. Guide grooves 301 matching the rollers 404 are opened at both ends of the guide rail 3 along its length direction, and the outer surfaces of the four rollers 404 conflict with the inner wall of the guide groove 301, and the two rollers 404 of the first connecting plate 402 and the two rollers 404 on the second connecting plate 403 are aligned with each other. The guide rail 3 forms a clamp, so that the roller 404 is not easily separated from the guide rail 3, so that it can guide and limit the moving direction of the LED headlight 2. The rotatable first connecting plate 402 and the second connecting plate 403 can change with the arc-shaped guide rail 3, and the first connecting plate 402 and the second connecting plate 403 are arranged at intervals, and there will be no interference when they rotate with each other, so that the roller 404 is stably slidably connected to the guide rail 3. When the rotating shaft 501 at the rear end rotates, the roller assembly 4 at the front end moves back and forth along the guide rail 3, and the front and rear cooperate with each other to form a uniform support for the LED headlight 2, making it less likely to wear and making its adjustment structure more stable and less prone to damage, so that the LED headlight can adjust the horizontal illumination angle according to the needs of the driver, so as to adjust the driver's visual area when turning at night, reduce blind spots at night, and improve night driving safety.

[0022] A limiting block 5011 is symmetrically provided on the outer surface of the rotating shaft 501, and a mounting hole 5021 matching the rotating shaft 501 is provided at the center of the bevel driven gear 502. A limiting groove 5022 matching the limiting block 5011 is provided on the bevel driven gear 502, and the limiting groove 5022 is communicated with the mounting hole 5021. The limiting block 5011 cooperates with the limiting groove 5022, so that the cooperation between the bevel driven gear 502 and the rotating shaft 501 is more firm and stable, and the bevel driven gear 502 will not slide in the circumferential direction of the rotating shaft 501, so that the power transmission is more stable.

[0023] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
