Abstract

The invention provides an under-driven three-degree-of-freedom ankle joint rehabilitation device which comprises a foot plate rotating mechanism, a power mechanism, a plantar flexion and dorsal extension and introversion and extroversion transmission mechanism, an inward-rotation and outward-rotation transmission mechanism, a first adjusting mechanism and a second adjusting mechanism, and the plantar flexion and dorsal extension and introversion and extroversion transmission mechanism is connected with the foot plate rotating mechanism. The inward-rotation and outward-rotation transmission mechanism is connected with the foot plate rotating mechanism, the first adjusting mechanism is connected with the plantar flexion and dorsal extension and introversion and extroversion transmission mechanism, and the second adjusting mechanism is connected with the inward-rotation and outward-rotation transmission mechanism. The rehabilitation device is comprehensive in rehabilitation training function, adjustable and diversified in function, can meet training postures needed by different patients and the full-range rehabilitation requirements for ankle joint rehabilitation, three-degree-of-freedom movement is achieved through one power source, and the three-degree-of-freedom ankle joint rehabilitation device has the cost advantage and is simple in structure and more reliable in movement.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation training devices, in particular to an under-drive three-degree-of-freedom ankle joint rehabilitation device. Background technique [0002] At present, the lower limb rehabilitation training for patients with hemiplegia and stroke has attracted the attention of researchers at home and abroad. With the increasing number of such patients and patients with lower limb movement disorders, it has become an urgent need to restore the living ability and rehabilitation training of these people. Therefore, it is of great significance to design a robot system that can perform rehabilitation training and neurological function recovery for disabled ankle joints and muscle groups. [0003] However, at present, most ankle joint rehabilitation robots have a single adjustable movement mode, and their freedom of movement can only be used for dorsiflexion / plantar flexion rehabilitation training, which ...
