Abstract:
1. A control system of resisting and assisting force for a rehabilitation apparatus comprising: a motor driving a shaft of rotating wheels of said rehabilitation apparatus to rotate, said rotating wheels are able to be pushed by hands or pedaled by feet of a user said motor able to supply said rotating wheels with a power assisting force of different degrees for pushing said rotating wheels; a resistance adjustment control device able to offer a resistance to said rotating wheels, a degree of said resistance designed by imitating frictional force of different road conditions, a friction coefficient of said resistance being arranged from small to large; a push force detecting device for detecting a push force produced by a user pushing manually or pedaling said rotating wheels when said rotating wheels depart from ground; and a motor output force control device connected to said resistance adjustment control device and said push force detecting device for gathering a resistance value preset by said resistance adjustment control device and said push force produced by a patient pushing manually or pedaling said rotating wheels when said rotating wheels depart from the ground, said motor output force control device controlling compensation of said motor based on a physical property analysis of a standard motor, said motor output force control device then controlling an output force of said motor to supply said power assisting force for pushing said rotating wheels; said rotating wheels of said rehabilitation apparatus departing from the ground, a user having his hands or feet push or pedal said rotating wheels of preset resistance, said motor output force control device automatically detecting a resisting force of said rotating wheels and said pushing or pedaling force when said rotating wheels of said rehabilitation apparatus depart from the ground and a user has his/her hands or feet push or pedal said rotating wheels of a preset resistance, said motor output force control device controlling said motor to supply adequate said power assisting force for pushing said rotating wheels, said resistance adjusted to become increasingly larger and larger by said resistance adjustment control device, the user finally able to push or pedal said rotating wheels by himself without help of said power assisting force with the force of the user's hands or legs increased by degrees, achieving effect of gradual rehabilitation of the hands or legs.
