Abstract

An automatic angle adjusting device for a rear-view mirror of a cart is provided. While the steering knuckle arm drives the steering knuckle to rotate around the kingpin to drive the steering wheel torotate, a spline shaft mounted on steering knuckle arm, a spline sleeve and the sector gear also rotate with the steering knuckle arm, and the sector gear drives the rack to move to the left or right, thereby pulling the cable to move, pulling the mirror driving cam to move along the driving cam guide rail, pushing the mirror driven cam to rotate along the ball joint connected with the fixed bracket, and driving the mirror to rotate. The device adopts a sector gear, a rack and a driving cam driven by a steering knuckle arm in an automobile steering mechanism, and an automatic angle adjustingdevice of a rear-view mirror of a large vehicle composed of a driven cam part, thereby realizing that the reflection angle of the rear-view mirror rotates simultaneously with the rotation of a steering wheel, thereby eliminating the visual blind area caused by the inner wheel difference when steering.

Description

technical field [0001] The invention relates to the technical field of vehicle driving safety, in particular to a device for automatically adjusting the angle of rearview mirrors of large vehicles. Background technique [0002] Due to the existence of the inner wheel difference of the vehicle, when the vehicle is turning, the trajectories of the front and rear wheels do not coincide, resulting in a blind area of ​​the inner wheel difference. The longer the vehicle body, the larger the area of ​​the blind area. The front part of the car passed through when turning, but the middle and rear parts of the vehicle did not pass, and the traffic accidents caused increased year by year, especially large trucks and buses. Small and medium-sized vehicles have relatively small areas of blind spots in the inner wheel differential, and fewer traffic accidents occur. Therefore, how to eliminate the blind spots caused by the inner wheel difference when turning large vehicles has become a k...
