Automobile headlamp adjusting device with spherical pair structure

Abstract

The invention relates to an automobile headlamp adjusting device with a spherical pair structure. The automobile headlamp adjusting device comprises a support frame arranged in a projection type headlamp shade, wherein the support frame is hinged to an outer spherical casing through a left support plate and a right support plate. An inner spherical casing is wrapped on the outer spherical casing to form a spherical pair, the front side of the inner spherical casing is provided with a projection type headlamp body, the back side of the outer spherical casing is provided with a motor rotating mechanism for driving the inner spherical casing to rotate horizontally and a motor transmission mechanism for driving the outer spherical casing to perform pitching swinging, the motor rotating mechanism is a gear and rack mechanism driven by a motor, and the outer spherical casing drives the inner spherical casing to synchronously perform the pitching swinging when performs the pitching swinging. The automobile headlamp adjusting device can provides active lighting and adapt to different gestures of an automobile body when the automobile turns, automatically adjusts horizontal deflection angles of headlamp light beams and pitching irradiation tilt angles, can meet the demands of actual road conditions well, and accordingly can improve the safety in running under the different road conditions, reduce the fatigue of a driver driving the automobile and strengthen the safety and comfort in driving.

Description

technical field [0001] The invention relates to an automobile headlamp adjusting device with a spherical substructure. Background technique [0002] As one of the most advanced automotive lighting systems in the world today, the Adaptive Front Lighting System (AFS) is mainly composed of three parts: projection headlights, headlight adjustment devices and control systems. The problem of poor vision, especially when driving in S-shaped curves, the effect is more obvious. The light control system of the adaptive front lighting system will predict the road conditions ahead to provide lighting patterns in different modes such as turning, intersections, expressways, urban roads, rainy days, etc., combined with the sensors equipped on the vehicle itself, the intelligent dimming system of AFS It can automatically adjust the distance of the light beam, the width of the irradiation area and even the intensity of the brightness, reduce the possibility of the dazzling effect of the veh...
