AI Technical Summary
The existing electric tricycle telescopic frame, after the rear frame is extended, causes the center of gravity to shift backward, affecting longitudinal stability and safety. During rapid acceleration, the vehicle will lift up. At the same time, the space between the rear seat and the front seat becomes smaller, resulting in a poor riding experience.
The rear frame is extended and retracted by a counterweight and drive unit, which uses a rack, rope and servo motor to drive the rear frame. The counterweight blocks are used to automatically adjust the center of gravity to ensure a proper distance between the rear seat and the front seat, preventing the center of gravity from shifting and the space from becoming cramped.
It improves the safety of the frame and the riding experience by automatically adjusting the center of gravity and seat distance, solving the problems of center of gravity shift and insufficient space, and enhancing the stability and comfort of the vehicle.
