[0001] The present application relates to the technical field of automobile accessories, and in particular to a dimming structure and an automobile lamp. Background Art
[0002] The up and down angles of the car headlights will change due to the car load, thereby changing the illumination range of the car headlights. If the illumination range of the car headlights is unreasonable, it will affect the driver's field of vision and easily cause traffic accidents.
[0003] In the prior art, the upper and lower angle adjustment of the light irradiation of the automobile headlight is generally composed of a motor, a motor bracket and a dimming bracket. The motor bracket is slidably connected to the housing of the automobile headlight, and the motor drives the motor bracket to slide. The motor bracket adjusts the dimming bracket up and down to achieve the upper and lower angle adjustment of the light irradiation of the automobile headlight.
[0004] Due to the large sliding friction between the motor bracket and the lamp housing, the motor bracket is prone to get stuck when sliding, affecting the smoothness of the up and down angle adjustment of the light irradiation of the car headlight.
[0005] Therefore, how to improve the smoothness of the up and down angle adjustment of the light irradiation of the automobile headlight has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0006] The present application proposes a dimming structure to improve the smoothness of the up and down angle adjustment of the light irradiation of the automobile headlight. The present application also proposes an automobile lamp.
[0007] In order to achieve the above-mentioned purpose, the present application provides a dimming structure, including a transmission bracket, a dimming bracket, a rotating shaft and a driving member.
[0008] The transmission bracket is connected to the dimming bracket, the rotating shaft is installed on the transmission bracket, and the rotating shaft is fixed on the housing of the lamp.
[0009] The driving member is connected to the transmission bracket and is used to drive the transmission bracket to rotate around the rotating shaft, so that the transmission bracket drives the dimming bracket to move up and down.
[0010] Preferably, in the dimming structure, the number of the dimming bracket is one, and the dimming bracket and the driving member are respectively located on both sides of the axis direction of the rotating shaft.
[0011] Preferably, in the dimming structure, the number of the dimming brackets is two, and the two dimming brackets are respectively located on both sides of the axis direction of the rotating shaft; and / or after,

[0015] Preferably, in the above dimming structure, the transmission bracket is provided with a ball head screw, the dimming bracket is provided with a ball head buckle, and the dimming bracket is connected to the transmission bracket via the ball head screw that cooperates with the ball head buckle.
[0016] Preferably, in the dimming structure, a cover plate is provided at least at one end of the rotating shaft in the axial direction.
[0017] The cover plate is provided with a rotation groove matched with the rotating shaft, and the cover plate is connected to the shell by bolts.
[0018] Preferably, in the above dimming structure, the driving element is a motor.
[0019] Preferably, in the above dimming structure, the transmission bracket is connected to the dimming bracket via a connecting bracket, and the connecting bracket is perpendicular to the transmission bracket.

[0040] The dimming bracket 2 is used to be connected to the light-emitting components of the lamp, such as the reflector cup and lamp of the lamp.
[0041] Here, the top and bottom are explained. The surface of the dimming bracket 2 used for installing the light-emitting component is the top of the dimming bracket 2, and the surface of the dimming bracket 2 not used for installing the light-emitting component is the bottom of the dimming bracket 2. The dimming bracket 2 moves in the direction of the top, that is, it moves upward, and the dimming bracket 2 moves in the direction of the bottom, that is, it moves downward.
[0042] The dimming structure disclosed in the present application utilizes a driving member 4 to drive the transmission bracket 1 to rotate around the rotating shaft 3 to realize the up and down movement of the dimming bracket 2, instead of the prior art method of realizing the up and down movement of the dimming bracket 2 by sliding the motor bracket up and down on the shell. The resistance of the transmission bracket 1 rotating around the rotating shaft 3 is less than the friction between the motor bracket and the shell, so that the rotation process of the transmission bracket 1 will not get stuck, thereby improving the flow of the up and down movement of the dimming bracket 2, thereby improving the smoothness of the up and down angle adjustment of the light irradiation of the lamp.
[0043] like Figure 1-Figure 8 As shown, the transmission bracket 1 is a long strip bracket, and the rotating shaft 3 passes through the transmission bracket 1 for installation. Preferably, the axis of the rotating shaft 3 is perpendicular to the length direction of the transmission bracket 1.

When the dimming structure is connected to the upper and lower adjustment points of the dimming bracket 2, the dimming structure is used to adjust the upper and lower angles of the dimming bracket 2. When the dimming structure is connected to the left and right adjustment points of the dimming bracket 2, the dimming structure is used to adjust the left and right angles of the dimming bracket 2, and the adjustment principle is the same.
