Lower limb assisted exoskeleton based on gravity support

Abstract

The invention relates to lower limb assisted exoskeleton based on gravity support. The lower limb assisted exoskeleton comprises a waist binding band, connecting bands used for connecting thighs to the waist and two legs, wherein the two legs are completely the same in structure; the upper part of each leg is fixedly connected with the corresponding position of the waist binding band through the corresponding connecting band; each leg comprises a thigh supporting part, a shank supporting part and a foot fixing part, which are sequentially connected; and a joint of the thigh supporting part and the shank supporting part is a knee joint. The lower limb assisted exoskeleton is characterized in that each thigh supporting part comprises a supporting base, a thigh secondary support, a thigh primary support and a binding band bound with the corresponding thigh, wherein the supporting base is fixedly arranged on the upper surface of the thigh primary support, length of the supporting base is greater than that of the thigh primary support, the rear part of the supporting base is connected with the lower part of the corresponding connecting band, and an area connecting the supporting base to the corresponding connecting band is a contact surface of buttocks when a user sits down, the middle part of the supporting base is equipped with the binding band bound with the corresponding thigh, and a convex blocking block with a through hole is arranged on a position, at the knee joint, of the thigh primary support.

Description

technical field [0001] The invention relates to the technical field of a lower limb power-assisted exoskeleton, in particular to a lower limb power-assisted exoskeleton based on gravity support, which can realize gravity support in different squatting postures. Background technique [0002] Employees in many industries have to stand for a long time or need to bend their knees to work, which often brings discomfort to the feet and knee joints and affects work efficiency, and even causes occupational diseases over time. Employees in these industries usually need to stand or bend their knees for a long time, but due to the reasons of work space and workplace, placing traditional seats may cause an obstacle. [0003] Most of the existing exoskeleton devices provide power for the human body to walk or improve the external load-bearing capacity of the human body. They are mainly worn on both sides of the human body, which cannot meet the gravity support for the human body itself. ...

AI Technical Summary

Problems solved by technology

The exoskeleton is mainly designed for long-term standing or bending knees to work normally, but the traditional chair cannot be used due to reasons such as occasions and working environments, and it solves the damage to the feet and knees of the human body due to long-term standing and knee bending question
