Passive walking aid exoskeleton

Abstract

A passive walking aid exoskeleton comprises a waist fixing and supporting device, a thigh supporting device, a shank supporting device and a foot supporting device. According to the key freedom degrees of hip, knee and ankle joints in the movement process and the human body space posture in the gait walking process of a healthy human body, ergonomic characteristics of the waist, abdomen, pelvis, thighs, shanks and the like are fully considered, and all main components are designed into curves meeting the mechanical property and bound to the lower limbs of a user to be worn and used. A high-friction-coefficient rubber pad is added at the articulated shaft; the locking effect on the knee joint and the ankle joint can be realized in the walking grounding link; the weight of the upper body ofthe user is downwards conducted to the ground through each component, so that the multi-body use effects such as indoor passive assisted walking, gait posture correction training and standing postureburden reduction are achieved, friendly use of experience, bionic intelligent use functions is achieved, lightweight dead-weight and low processing cost are realized, the blank of the field is filledup, and commercialized production, popularization and promotion are facilitated.

Description

technical field [0001] The invention belongs to the field of human body movement aiding mechanical equipment, and relates to a passive walking aid exoskeleton capable of assisting gait movement for patients with lower limb motor dysfunction. Background technique [0002] The walking ability of the human body is one of the indispensable and important behaviors for realizing autonomous life. For patients with lower limb motor dysfunction or special occupational groups who need to walk for a long time, bend over, etc., the gait movement can be enhanced or extended by auxiliary equipment. ability is of great value. At present, domestic and foreign sports walking aids or gait training equipment with simple structures are common in the field of fitness power equipment, and it is difficult for patients to achieve the effect of bionic motion assistance, while non-bionic gait motion aids will give patients musculoskeletal and It causes different degrees of abnormal rehabilitation, o...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign sports walking aids or gait training equipment with simple structures are commonly used in the field of fitness power equipment, and it is difficult for patients to achieve the effect of bionic motion assistance, while non-bionic gait motion assisting equipment can give patients musculoskeletal, etc. Cause different degrees of abnormal rehabilitation, or cause abnormal forced assistance, which limits the comfort of exercise

At present, most of the equipment dedicated to bionic gait assistance at home and abroad are active multi-degree-of-freedom mechanical systems. The mechanical structure and control system are complex, costly, and expensive. promotion
