Articulated rear-view mirror steering synchronizer for motor vehicle

The utility model discloses a hinging type vehicle rear view mirror steering synchronizing device, and is composed of an angle displacement sensor, a controller, a stepper motor driver and a stepper motor which are connected through conducting wires. The angle displacement sensor is arranged at the hinging position between a hinging type vehicle head and a vehicle body, the controller and the stepper motor driver are arranged on a driving cab front panel, and the stepper motor and a rear view mirror are arranged into a whole. When the vehicle is turned, the angel displacement sensor sends the signal to the controller, the controller transfers the signal to the stepper motor driver to drive the stepper motor, and the stepper motor drives the rear view mirror to rotate to a corresponding angle, thus eliminating the blind area, guaranteeing that the driver can observe the vehicle body and the surrounding situation through the rear view mirror, and reaching the purpose of security driving. The controller can be used to control the stepper motor manually to adjust the angle of the rear view mirror.
