The frame structure adopts patented technology, and the multi-link mechanism (automatic / manual) can be folded to realize (full-automatic / semi-automatic) fast and efficient folding and opening actions. It has the functions of electric driving and push walking, and is safe, reliable and easy to operate. A dedicated brushed controller is used to achieve intelligent control of the motor, and independent rocker operations are used to achieve forward, differential cornering, and low-speed reversing, making it easy to control a wheelchair. The energy-saving and high-efficiency DC brushed motor has the advantages of high performance, long life and low energy consumption.
