The handlebar rotates to make the two front wheels steer synchronously. The transmission that connects the handlebar riser and the front fork steering tube can also be connected by a universal shaft. The guide wheel can be directly installed on the rear wheel beam, which simplifies the structure. After buckling, the guide wheel touches the ground. The guide wheel is used to prevent the vehicle from overturning after buckling.

[0008] The steering control servo is a position (angle) servo driver. Generally speaking, it is mainly composed of the following parts: steering wheel, reduction gear set, position feedback potentiometer, DC motor, control circuit, etc., and corresponding programs are compiled to control the steering of the front wheels.

[0009] When in use, the motor drives the shaft to rotate, and the rotating worm gear opens and closes the angle of the rear wheel frame, the seat support connecting rod and the front wheel frame beam, and stands up and puts it on the handlebar, and locks it for people to ride. When not in use, the vehicle is buckled, the guide wheel touches the ground, and the steering motor, power components and brake disc are controlled by the handlebar handle through the control line to make the vehicle turn, move forward or stop. The advantage is that the low vehicle body after buckling is convenient for becoming an intelligent vehicle controlled by a computer, and can automatically travel back and forth between the boarding and disembarking positions and the garage where the vehicle is parked, which is convenient for users.
