[0002] A vehicle headlight with a function to eliminate bright spots in light is disclosed in patent publication number CN221592635U. The patent describes a method where "a micro motor drives a screw to rotate, the screw drives a threaded tube to move to the right, the threaded tube drives a guide plate to move to the right along a guide post, the guide plate drives a reflector and a bulb to move to the right, and the focus is adjusted by changing the distance between the bulb and the lens, while simultaneously observing the light illumination effect until the bright spots disappear." In this patent, the threaded drive allows the reflector to move, changing the focus between the bulb and the lens. While the bulb's wiring meets the requirements for movement, this movement can easily lead to poor contact in the bulb, requiring improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a vehicle headlight that is simple in structure, reasonably designed, and easy to use, capable of eliminating bright spots from angular light. This is achieved by moving the lens to change the distance between the lens and the reflector bowl, and by changing the angle of the lens to change the focus between the lens and the bulb.

[0011] Through the above technical solution design, the electric push rod drives the support block to move, thereby moving the lens and changing the distance between the lens and the bulb. The drive motor is started, causing the lead screw to rotate, which in turn drives the drive block to move through the thread drive. This drives the rotating gear to mesh and drive the support shaft to rotate the lens, changing the angle and thus changing the focus between the lens and the bulb.

[0012] As a further improvement of this utility model, the lampshade is fitted onto the right side of the light box; and limit clips are fixedly provided on the inner walls of both the upper and lower sides of the lampshade. The limit clips are configured with an "L" shape; the horizontal end of the limit clip is in contact with the right side of the light box.

[0013] The above technical solution design limits the connection between the light box and the lampshade.

[0014] As a further improvement of this utility model, several slots are evenly spaced on the upper and lower sides of the lampshade, and a rod is inserted into the slot. The inner end of the rod is provided with a threaded platform, which is inserted into the lamp box by threaded connection. A frustum is fixedly provided on the outer end of the rod, and the frustum contacts the outer side of the lampshade.

[0015] The above technical solution design strengthens the fixation between the lampshade and the light box.

[0016] As a further improvement of this utility model, a plug is fixedly provided on the left side of the mounting block.

[0020] The working principle of this utility model is as follows: The reflector bowl is installed inside the light box by inserting the mounting block and the fixing block; the light from the bulb shines on the reflector bowl, and then shines on the lens after being reflected by the reflector bowl. After the light is refracted by the lens, it shines out through the lampshade. When a bright spot appears in the above process, firstly, the electric push rod is started to move the support block to adjust the distance between the lens and the reflector bowl. Secondly, the drive motor is started to rotate the lead screw, which moves the drive block through the screw thread to mesh with the rotating gear, causing the support shaft to rotate the lens and change the angle to change the focus between the lens and the bulb.
