Embodiment approach

[0013] An AFS horizontal angle adjustment actuator includes a lighting assembly 1 and a base 30 for fixing the lighting assembly 1. The lighting assembly 1 is connected with a driving device 10 for driving the lighting assembly 1 to rotate left and right. The lighting assembly 1 is fixed on the base 30, the driving device 10 is connected with the lighting assembly 1, and the driving device 10 makes a forward and backward movement, thereby driving the lighting assembly 1 to rotate left and right along its own rotation axis. Driving the lighting assembly 1 to rotate can realize the adjustment of the small angle rotation of the lighting assembly 1 . Here, the front and rear directions refer to the directions in which the front and the rear of the vehicle are located, respectively.

[0014] like figure 1 As shown, the lighting assembly 1 is provided with a fixing frame 20 outside, and the fixing frame 20 is connected with the driving device 10 . The lighting assembly 1 and the f...

Abstract

The invention discloses an adaptive front lighting system (AFS) horizontal angle adjustment actuating mechanism, which comprises a lighting assembly and a base for fixing the lighting assembly. The lighting assembly is connected with a driving device which drives the lighting assembly to rotate left and right. The lighting assembly is fixed on the base; and the driving device which is connected with the lighting assembly performs a feed movement in a front-and-back direction so as to drive the lighting assembly to rotate left and right along a rotating shaft per se. As the movement in the front-and-back direction is used for driving the lighting assembly to rotate, rotation adjustment of the lighting assembly in the horizontal direction can be realized. The AFS horizontal angle adjust actuating mechanism disclosed by the invention is simple in structure, small in installation space and high in control precision, and can realize servo adjustment of an illumination angle of a big headlight in the horizontal direction.

Description

technical field [0001] The invention belongs to the field of auto parts devices, and in particular relates to an AFS horizontal angle adjustment actuator. Background technique [0002] When driving a vehicle at night, the quality of vehicle lighting is closely related to the safety of drivers and passengers. The traditional vehicle headlight system cannot properly adjust the lighting effect of the headlight according to the change of the lighting environment during lighting. The light of the headlight is consistent with the driving direction of the vehicle. Under adverse weather and other conditions, there are dark lighting areas, and the safe driving performance of the vehicle is low. [0003] At present, the more advanced vehicle headlight system applied to vehicles is AFS (Adaptive Front-lighting System, Adaptive Front Lighting System), which can automatically optimize the illumination distribution of lights according to changes in driving road conditions and vehicle sta...
