The application belongs to the field of
ankle assistance and training devices, and specifically discloses a bionic external
tendon device and method for
ankle assistance and training, which comprises a
forefoot palm protective sleeve, a rear
heel protective sleeve, a lower leg protective sleeve, an external
tendon rope group, a limiting mechanism and a power mechanism; one end of each of two first external
tendon ropes is connected with the bottom of the
forefoot palm protective sleeve, and the two first external tendon ropes are connected with the power mechanism after sequentially passing through the guide holes in the rear
heel protective sleeve and the rear side of the lower leg protective sleeve; one end of a second external tendon
rope is connected with the top of the
forefoot palm protective sleeve, and the second external tendon
rope is connected with the power mechanism after passing through the guide hole in the front side of the lower leg protective sleeve. The application can realize multidimensional
coordinated movement of the foot and the
ankle joint, and can realize hierarchical control of the foot bottom tension and the ankle joint auxiliary force. Through the
coordinated movement of the foot and the ankle, the assistance and
training effect are improved. In the application, the two first external tendon ropes of the foot bottom are cross arranged, and when the first external tendon ropes are pulled, the arch of the foot is pressed, and the training on the arch of the foot is enhanced.
