Embodiment Construction

[0015] The present invention will be further explained below according to the drawings and specific embodiments of the specification.

[0016] Such as figure 1 As shown, a car headlight follow-up steering direct drive system includes a lamp body 1, a microcontroller 4, a rotating shaft 5, a rotary encoder 6, and a disc motor 7, and the center of the rotating shaft 5 and the disc motor 7 The shafts are concentrically connected, the microcontroller 4 is connected with the disc motor 7 and the rotary encoder 6 through wires, the rotating shaft 5 and the lamp body 1 are connected through the first bracket 2, and the first bracket 2 It is fixed at the center of gravity of the lamp body 1 to ensure that the lamp body 1 can freely rotate around the rotating shaft 5 on the horizontal plane. The disc motor 7 has a disc motor 7 rotor, and a point on the disc motor 7 rotor is connected to the tail shell of the lamp body 1 through the second bracket 3, or as figure 2 As shown, a point ...

Abstract

The invention discloses a follow-up steering direct-drive system of an automobile headlamp. The follow-up steering direct-drive system comprises a lamp body, a micro controller, a rotating shaft, a rotating encoder and a disc-type motor, wherein the rotating shaft is concentrically connected with a center shaft of the disc-type motor, the micro controller is connected with the disc-type motor and the rotating encoder through leads, the rotating shaft is connected with the lamp body through a first support, the disc-type motor is provided with a disc-type motor rotor, and a point on the disc-type motor rotor is connected with a lamp body shell through a second support. The device is free from gear drive, simple in structure, high in reliability and low in cost, and can meet the high steering sensitivity requirement of a headlamp, ensure the steering rapidity and the steering angle accuracy of the lamp body and timely reflect the real intention of a driver.

Description

technical field [0001] The invention relates to a follow-up steering direct drive system, in particular to a follow-up steering direct drive system for automobile headlights. Background technique [0002] Generally, car headlights have a certain lighting range regardless of the brightness. When turning at night or under poor light conditions, there will be a certain "blind spot" due to the problem of driving angle. In the case of fixed lighting, the blind spot is unavoidable, 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 vehicle body, so as to illuminate the "unreached" area in time, provide all-round safety lighting, and ensure the safety of turning at night. [0003] Patent application number 201220083167.5 "asynchronous control follow-up headlight system", application number 201220399526.8 patent "automatic fol...
