Automatic follow-up two-degree-of-freedom steering direct-drive system of automobile headlamp

Abstract

The invention discloses an automatic follow-up two-degree-of-freedom steering direct-drive system of an automobile headlamp. The automatic follow-up two-degree-of-freedom steering direct-drive system comprises a lamp body, a two-degree-of-freedom spherical motor, a support and a micro controller, and is characterized in that the support is used for supporting the lamp body, the two-degree-of-freedom spherical motor comprises a stator and a rotor, the support is arranged in a central point of the end part of the two-degree-of-freedom spherical motor, and the micro controller is connected with the two-degree-of-freedom spherical motor through a wire. The automatic follow-up two-degree-of-freedom steering direct-drive system is free from gear drive, simple in structure, high in reliability and low in cost, and can meet the high horizontal and vertical two-degree-of-freedom steering sensitivity and accurate horizontal and vertical two-degree-of-freedom steering angle requirements of the headlamp, thus conforming to the intention of a driver. Direct horizontal and vertical two-degree-of-freedom angle adjustment of the lamp body is realized, the steering rapidity and the steering angle accuracy of the lamp body are ensured, and a blind area is lightened.

Description

technical field [0001] The invention relates to an adjusting device for the lighting direction, angle and width of a headlight of an automobile, in particular to an automatic accompanying two-degree-of-freedom steering direct drive system for the headlight of an automobile. Background technique [0002] The direction of the headlights of traditional vehicles is fixed, and the headlights are consistent with the driving direction of the vehicle. In the case of poor vision at night or due to weather, lighting "blind spots" will inevitably appear when turning; Various changing axle loads such as slopes and downhills lead to changes in the inclination angle of the headlights, which cannot effectively illuminate the road in the direction of the vehicle. In these cases, if there are obstacles on the road, traffic accidents may result. [0003] The two-degree-of-freedom steering technology of automobile headlights is mainly to improve the poor vision caused by night and weather fac...

AI Technical Summary

Problems solved by technology

The system is complex in structure, expensive to manufacture and prone to failure

In addition, because the steering of the lamp body is completed by the motor-driven gear, there are problems such as steering lag, poor steering sensitivity, steering angle deviation, and crawling, which cannot reflect the driver's true intention.
