Supporting phase bearing self-locking lower limb rehabilitation device

Abstract

The invention discloses a supporting phase bearing self-locking lower limb rehabilitation device, and relates to the technical field of rehabilitation training devices. The supporting phase bearing self-locking lower limb rehabilitation device comprises a waist and crotch structure, a thigh structure, a knee joint mechanism, a shank structure and a shoe body which are sequentially arranged from top to bottom, and a steel wire rope adjusting mechanism used for adjusting the pay-off length of a steel wire rope is arranged on the waist and crotch structure; and the top end of the thigh structureis rotationally connected with the waist and crotch structure, the bottom end is fixedly connected with the knee joint mechanism, the top end of the shank structure is fixedly connected with the kneejoint mechanism, and the bottom end is connected with the shoe body through a spring. A steel wire rope can be used for driving a chuck to rotate and be tensioned to enable chuck clamping teeth to beengaged with output disc clamping teeth, structural self-locking of the knee joint mechanism is achieved when a user is in a supporting phase, the steel wire rope can be loosened through the thigh lifting action of the user in a pre-swinging phase, and the chuck rotates under the elastic force effect of a torsional spring and is disengaged from structural self-locking of an output disc, so that the motor is used for supplying power to provide knee joint action assistance, the locking state is reliable and stable, safety is high, and overall energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training devices, in particular to a rehabilitation device for knee joint walking function rehabilitation training. Background technique [0002] Lower extremity joint degeneration is a common degenerative disease, which mainly occurs in the elderly and some occupational groups with long-term mechanical stress distribution imbalance or excessive load on lower extremity joints. Patients with degeneration of lower extremity joints have symptoms such as knee joint pain and stiffness, difficulty going up and down stairs, soft knee joints when going downstairs, easy to fall, pain and stiffness when squatting, joint pain and pain, and lameness. have a significant impact on normal life. [0003] Lower limb joint degeneration can be alleviated through lower limb rehabilitation training. At present, rehabilitation training is generally assisted by wearable lower limb rehabilitation devices. In the...
