Walking-aiding exoskeleton power-free mechanical foot

The invention discloses a walking-aiding exoskeleton power-free mechanical foot. A rubber shoe sole body of a sensing shoe sole of the walking-aiding exoskeleton power-free mechanical foot is fixed to a metal base plate. A circular-arc-shaped toe cap is arranged at the front end of the rubber shoe sole body. The front portion and the back portion of the rubber shoe sole body are each provided with two miniature pressure sensors. A long-groove connecting plate and a shoe sole connecting base which are connected through a rotating hinge are arranged on the metal base plate. The long-groove connecting plate is in threaded connection with protruding blocks on the metal base plate through bolts. A shaft base in a mechanical ankle joint is fixedly connected with the metal base plate. A knuckle bearing is fixed in a center through hole of a lug base. A shaft arranged on the shaft base penetrates through the center of the knuckle bearing. An external connection plate is fixedly connected with the lug base. Two pull-press springs are arranged between the external connection plate and the metal base plate. The walking-aiding exoskeleton power-free mechanical foot is simple in structure and convenient to wear, and it can be guaranteed that exoskeleton can provide supporting force for the human body.
