Abstract

PROBLEM TO BE SOLVED: To turn the illuminating light ray of a vehicle light in synchronization with a handle so as to form a clear view of the road status in the curving direction by providing a motor driving mechanism adapted to receive a turning angle of a turning angle transmission device to drive or move a motor device to a turning angle value. SOLUTION: When a handle is turned to curve, a handle shaft 91 drives a pull rod 93 and a tract rod 10 to turn to one side, and the tract rod 10 immediately pulls an interlocking rod to be moved synchronously so that the angle deviation amount and the deviation direction of the tract rod 10 can be transmitted to a turning angle control switch 13 through the interlocking rod 12. Further the operating angle of the equivalence is transmitted to a servo motor 3 by electric connection so that the servo motor 3 can drive a vehicle light seat 2 to turn synchronously and at the same angle.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination control system for a vehicle headlight, and more particularly to a vehicle headlight and a fog light which are rotated synchronously with a steering wheel in a turning direction of a vehicle so that a pedestrian, a vehicle or an obstacle there. The present invention relates to an irradiation angle control device for an automobile headlight that can prevent an accident such as a collision or an obstacle from occurring.

2. Description of the Related Art A conventional vehicle light is generally mounted in a manner in which a housing is fixed to a vehicle body, and has a limited width in which the light can be projected. When running on a dark night road, the driver cannot clearly see the people, vehicles or objects on the left and right sides in front of the running vehicle, regardless of whether the headlights or fog lights are on. . This situation does not hinder the vehicle if the road surface is straight, but when the vehicle curves, as shown in Fig. 7, the driver becomes habitual due to concerns about driving safety. Be sure to look into the right or left road surface first in the direction of the curve, and turn off the steering wheel with confidence when you see that there are no pedestrians, vehicles or obstacles on the road surface or roadside. Is still illuminating the front, so the driver does not always know the road condition A in the direction of the curve in advance, that is, in the early stage when the driver makes a curve, he has already turned the steering wheel and turned the front wheel tires. It turns slightly together and starts turning the body in conjunction with it,
As shown in FIG. 7, since the degree of curve of the vehicle body is always behind the degree of rotation of the wheel tires (handles), for example, after the driver turns the steering wheel and reaches a half curve, the vehicle body first curves by a small angle. However, the light at the front end of the vehicle does not allow the driver to sufficiently determine the road condition A, and often causes misconduct such as the vehicle hitting an obstacle in the middle of a curve. In particular, when driving on a mountain road at night, this situation is likely to occur, it is dark and winding, so often the beam of the vehicle light is blocked by the trees on the roadside, and the road condition ahead can not be clearly seen, Accidents such as rushing into the roadside easily occur.
