Embodiment Construction

[0017] The present invention will be further explained below based on the drawings and specific embodiments of the specification.

[0018] Such as figure 1 , figure 2 As shown, an automotive headlight follow-up steering arc driving system includes a lamp body 1, an arc motor 3, a microcontroller 4, a position sensor 5, and a rotating shaft 7. The rotating shaft 7 is vertically installed on the arc motor 3, the microcontroller 4 is connected to the arc motor 3 and the position sensor 5 through a wire, and the rotating shaft 7 is connected to the lamp body 1 through the first bracket 2, such as image 3 As shown, the arc motor 3 includes an arc motor stator 3-1 and an arc motor mover 3-2. The center point of the arc motor mover 3-2 passes through the second bracket 6 and the lamp body 1. The shell is connected. Fix the front end of the lamp body 1 on the first bracket 2, and then fix the first bracket 2 on the shaft 7. The tail of the lamp body 1 is connected to the arc motor move...

Abstract

The invention discloses a car headlamp follow-up steering arc driving system. The car headlamp follow-up steering arc driving system comprises a lamp body, an arc motor, a micro controller, a position sensor and a rotation shaft, wherein the rotation shaft is located at the circle center of the arc motor, the micro controller is connected with the arc motor and the position sensor through wires, and the rotation shaft is connected with the lamp body through a first support. The arc motor comprises an arc motor stator and an arc motor rotor, wherein one point of the center of the arc motor rotor is connected with an outer shell of the lamp body through a second support. The car headlamp follow-up steering arc driving system does not need gear transmission, and is simple in structure, high in reliability and low in cost.

Description

Technical field [0001] The invention relates to an automobile headlamp drive system, in particular to an automobile headlamp follow-up steering arc drive system. Background technique [0002] Generally, car headlights have a certain lighting range regardless of the brightness. When driving at night or under poor light conditions, there will be a certain "blind zone" due to the driving angle. In the case of fixed lighting, this blind spot is inevitable, which affects driving safety to a certain extent. The light follow-up steering device can automatically adjust the steering angle of the headlights according to the driving speed and the steering angle of the body, so as to illuminate the "unreached" area in time, provide a full range of safety lighting, and ensure the safety of turning at night. [0003] The patent "Asynchronous Control Follow-up Steering Headlight System" with the application number of 201220083167.5, the patent "Automatic Follow-up Steering Headlight Device" with...
