A wearable lower limb rehabilitation training device

Abstract

The invention provides a wearable lower limb rehabilitation training device which comprises a base, a column, a waist bracket, knee-joint motion control units and hip joint motion control units, wherein the column is installed on the base, the waist bracket is installed at the top of the column and is provided with two protective frames, each protective frame is provided with the hip joint motion control unit and the knee-joint motion control unit, each hip joint motion control unit comprises a hip joint motor, a thigh rod, a thigh connecting rod, a thigh driving rod and a thigh layer board, and each knee-joint motion control unit comprises a knee-joint motor, a shank rod, a shank connecting rod, a shank driving rod and a pedal. The upper end of the shank rod is connected with the thigh rod through a thigh joint shaft. The device can realize lower limb rehabilitation training of patients or the old, improve a training effect, and further improve the comfort level of a user. Meanwhile, the device can be suitable for crowds in different body types by adopting a leg length, height and width adjusting mechanism.

Description

technical field [0001] The invention relates to a medical rehabilitation device, in particular to a lower limb rehabilitation training device. Background technique [0002] The population aging in our country is becoming more and more serious, the body and various physiological functions of the elderly are declining day by day, and various traffic accidents are constantly increasing. The number of people with hemiplegia, stroke, and paraplegia continues to increase, resulting in motor dysfunction in the lower limbs of this group of people, and the burden on families and society is getting heavier. Therefore designing a kind of lower limb rehabilitation training device is the urgent need of this class patient in my country. [0003] At present, there are many related public reports at home and abroad, and the functions are very similar. Several recent typical public documents include: mobile wearable lower limb exoskeleton rehabilitation robot (patent application number 2012...

AI Technical Summary

Problems solved by technology

The six-bar humanoid gait power-assisted walking mechanism (patent application number 200810137092.2) proposes a lower limb rehabilitation training mechanism, which realizes the movement of the thigh and calf through a motor, but the mechanism is limited by the needs of the population, and the control law is limited by the structural parameters. Constraints, can only achieve motion control of a specific trajectory

In short, there are many types of lower limb rehabilitation training devices, but most of them have complex structures and are relatively cumbersome.
