Problems solved by technology

The active and passive ankle joint rehabilitation device (patent application number 201310014261.4) proposes an overall frame structure, but they are all based on the direct drive mode of the motor, and the patient needs to stand directly above the rehabilitation device when using it. It is extremely inconvenient for patients; an ankle joint rehabilitation device (patent application number 201310421566.7) proposes an ankle joint rehabilitation device based on a parallel mechanism. In the laboratory, it is difficult to popularize and use in the market

Abstract

The invention is to provide a three degree-freedom ankle rehabilitation training apparatus comprising a housing, an ankle revolution unit, an ankle dorsal stretch plantar flexion unit and an ankle inward-outward turning unit. The ankle revolution unit is mainly formed by a revolution motor, a housing, a small gear, a large gear, a large gear connection plate and a lower layer rack; inwardly, outward and annular rotation of the ankle can be achieved via driving of the revolution motor; the ankle dorsal stretch plantar flexion unit is mainly formed by an ankle stretch electric cylinder, a middle layer rack and a foot pedal; with control of extension stroke of a stretch electric cylinder push rod, dorsal stretch and plantar flexion actions of the ankle can be achieved; the ankle inward-outward turning unit is mainly formed by an ankle over-turning electric cylinder, a middle layer rack and a lower layer rack; and with control of extension stroke of an over-turning electric cylinder push rod, inward-outward over-turning actions of the ankle can be achieved. All basic actions for rehabilitation training can be achieved for the ankle.

Description

technical field [0001] The invention relates to a rehabilitation device, in particular to an 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] At present, there are many ankle joint rehabilitation devices, most of which use parallel mechanisms, which have many degrees of freedom, large range of motion uncertainty, low safety factor, and difficult control. The active and passive ankle joint rehabilitation device (patent appli...
