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
The invention belongs to auto parts and components device field, be specifically related to a kind of AFS level angle and regulate actuating unit.
Background technology
At the driving vehicle at night, the quality of car lighting and driver's safety are closely bound up.Suitable adjustment can not be made to the illuminating effect of head lamp according to the variation of lighting environment by traditional vehicle head lamp system when illumination; The light and the vehicle heading of head lamp are consistent; At bend, at a high speed, have the illumination dark space under the rural area, situation such as city and adverse weather, the safe driving of vehicle performance is lower.
At present; Being applied in vehicle head lamp system advanced on the vehicle is AFS (AdaptiveFront-lighting System, self-adaptive headlamp system), can distribute the illumination of light automatically according to the variation of go road conditions and vehicle-state and carry out the optimization adjusting; Make the irradiation light and the actual travel road conditions of automotive headlamp adapt; Its direction of illumination also no longer with vehicle heading remain consistent, thereby strengthened the illuminating effect of automotive headlamp, improve the safe driving of vehicle performance.AFS need partly install corresponding actuating unit at automotive headlamp at the illuminating effect of regulating head light, and AFS drives the head light operation through control executing mechanism, thereby realizes the servo-actuated in the horizontal direction of head light irradiating angle.But the space structure of existing AFS actuating unit is complicated, productive costs is higher, and control accuracy is lower, and installing space is big, thereby has limited the application of AFS on vehicle.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, control accuracy is high, and the AFS level angle that installing space is little is regulated actuating unit, can realize head light irradiating angle follow-up adjustment in the horizontal direction.
For addressing the above problem, the present invention adopts following scheme: a kind of AFS level angle is regulated actuating unit, comprises the base of light fixture and built in light assembly, it is characterized in that: be connected to one on the light fixture and order about the actuating device that light fixture is done left-right rotation.
In the technique scheme, light fixture is fixed on the base, and actuating device links to each other with light fixture, and actuating device feeds motion as fore-and-aft direction, makes left-right rotation thereby order about light fixture along himself rotating shaft.Thisly drive light fixture through moving on the fore-and-aft direction and rotate, can realize the adjusting that the low-angle of light fixture rotates.The present invention is simple in structure, and installing space is little, and control accuracy is high, can realize head light irradiating angle follow-up adjustment in the horizontal direction.
