[0047] With the rapid development of the automotive industry and the increasing diversification of consumer demand, as an important part of the car, the function and design of the car light are constantly updated and iterated. In order to facilitate the adjustment of the light type and ensure driving safety, a light adjusting mechanism is usually provided in the car light, which can drive the lighting module to swing within a certain range, thereby meeting the lighting needs under different road conditions. In recent years, with the progress of science and technology and the improvement of consumer aesthetic concepts, consumers' functional demands for car lights have been increasing. Therefore, multifunctional car light assemblies have appeared on the market, such as high-tech projection headlights that integrate lighting and projection functions, multi-eye headlights that achieve more extensive and uniform lighting through the combination of multiple light sources, and some front headlights with special shapes that provide a more technologically advanced appearance based on the lighting function. The design of these multifunctional car lights is constantly updated, not only improving the practicality of the car, but also greatly improving the aesthetic appearance of the car.

[0048] However, according to the applicant's research, with the increasing complexity of multifunctional car light design, the height of the car light is constantly increasing, which brings some technical problems. Because such car lights usually have a high height, the distance between some light adjusting points of the light adjusting mechanism and the engine top cover is too large. These light adjusting points are relatively deep and hidden in the complex structure between the car light and the car frame sheet metal. At the same time, the gap between the car light and the surrounding sheet metal parts is relatively narrow, which brings great inconvenience to the light adjusting work. When adjusting the light, the operator has difficulty in accurately and quickly positioning the light adjusting tool to these relatively deep light adjusting points. This phenomenon not only increases the difficulty of light adjustment, but also reduces the efficiency of light adjustment, and even the operator may start to rotate the light adjusting tool without aligning the light adjusting point, which may cause the structure in the light adjusting point to slip and be damaged.

[0049] In view of this, the utility model provides a light adjusting mechanism to solve the above technical problems.

[0050] It should be noted that the "light adjustment" referred to in the above content at least includes up-down light adjustment of the car light and left-right light adjustment of the car light, wherein the up-down light adjustment of the car light refers to the process of adjusting the light beam or light type of the car headlight (headlight) in the vertical direction (up-down direction). The main purpose is to ensure that the light of the car light can correctly illuminate the road, while avoiding dazzling other road users (such as the driver of the oncoming vehicle). The left-right light adjustment of the car light refers to the process of adjusting the light beam or light type of the car headlight (headlight) in the horizontal direction (left-right direction). It is mainly to ensure that the light of the car light can accurately illuminate the lane range in front of the vehicle, while avoiding unnecessary interference to vehicles or pedestrians in adjacent lanes.
