The first mounting frame 100 and the second mounting frame 200 are disposed at two ends of the linkage structure 300, and the first mounting frame 100 and the second mounting frame 200 are respectively hinged to two ends of the linkage structure 300. After the first lamp unit structure is driven by the driving assembly (not shown) to move, the linkage structure 300 is driven by the first mounting frame 100 to move, and then the linkage structure 300 drives the second lamp unit structure to move by the second mounting frame 200, so that the linkage of the first lamp unit structure and the second lamp unit structure is finally realized. The relative positions of the two ends of the linkage structure 300 can be adjusted, so that the length of the linkage structure 300 can be adjusted.

The movement of the first lamp unit structure and the second lamp unit structure adjusts the inclination angles or positions of the first lamp unit structure and the second lamp unit structure. It can be understood that the light type refers to the angle and shape of the light of the vehicle lamp, and can be characterized as the illumination position of the light of the vehicle lamp projected on a certain vertical plane. For example, the first lamp unit structure and the second lamp unit structure are matched and then projected to an illumination position on a certain vertical plane. When the vehicle is driven to the right, in order to avoid the influence of the irradiation of the vehicle lamp on the sight line and the safety of the opposite vehicle, the light type is characterized in that the left light and shade cut-off line is low, and the right light and shade cut-off line is high, so that the opposite vehicle is not influenced, and pedestrians and vehicles on the right road can be clearly seen.

To enable adjustment of the length of linkage structure 300, in one embodiment, linkage structure 300 is a telescoping member. The linkage structure 300 adjusts the length by stretching and retracting to drive the first mounting rack 100 and the second mounting rack 200 at the two ends to move relatively, and adjusts the positions and the inclination angles of the first lamp unit structure on the first mounting rack 100 and the second lamp unit structure on the second mounting rack 200.
