The application discloses a six-degree-of-freedom light high-compatibility foot-
ankle rehabilitation exoskeleton, which comprises an
ankle-
tibia connecting rod module, an
ankle joint shaft module, a
forefoot fixing module and a hindfoot fixing module; the ankle-
tibia connecting rod module is used for being fixed in parallel with a lower leg and providing a power assisting
anchor point at the back side of the lower leg; the
forefoot fixing module and the hindfoot fixing module are respectively used for being fixed with the front end and the rear end of the foot of a wearer and providing an end power assisting
anchor point at the
heel; the ankle joint elastic element is directly contacted with the shoes of a user, and six-degree-of-freedom flexible interaction force is generated. The traditional foot-ankle
exoskeleton is limited to
toe flexion and dorsiflexion movement, and the elastic element design of the application can adapt to any movement of the foot-ankle within a safety limit, that is, the movement of the foot-ankle, such as
internal rotation,
external rotation, internal collection, external expansion,
toe flexion and dorsiflexion. The application can effectively increase the activity of the foot-ankle, greatly improve the man-
machine compatibility, and solve the problem that the existing ankle
exoskeleton robot cannot meet the daily functional requirements of patients due to the heavy body configuration and single degree-of-freedom configuration.
