A leg exoskeleton device for assisting the mobility of the elderly

Abstract

A leg exoskeleton device for assisting the movement of the elderly belongs to the technical field of intelligent equipment for assisting the living of the elderly, and includes a crutch, a magnetic attraction mechanism and a variable-movement linkage mechanism. The calf support bar of the motion-variable link mechanism cooperates, and the crutches are placed under the user's armpit to assist walking. Through the analysis of the existing human leg movement, the approximate movement law of the leg in the natural state is extracted. During the movement, the thigh takes the thigh root as the center of rotation, and the calf takes the calf root as the center of rotation. When the thigh turns outward, the calf turns slightly inward with a small angle. According to the specific conditions of different motion states, a motion-variable linkage mechanism is designed to ensure that the motion state of the leg exoskeleton in the natural state is similar to that of a normal human leg during the motion process.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment for assisting the living of the elderly, and in particular relates to a leg exoskeleton device for assisting the elderly to move. Background technique [0002] With the continuous growth of people's age, when they pass through the prime of life and enter the old age, various functions of the body gradually appear problems, and the health index of the elderly in all aspects will be in a state of decline, and the legs are sore and weak. One of the serious problems. [0003] Soreness and weakness in the legs will have a great impact on the daily life of the elderly, such as: being unable to sit and stand normally, getting in and out of bed, going to the toilet, bathing, walking, etc. [0004] However, the existing wheelchair design is more to help the elderly to move their positions, which cannot solve most of the above-mentioned problems, and has certain limitations in the range of ac...

AI Technical Summary

Problems solved by technology

[0004] And the existing wheelchair design, more is to help the elderly to move the position, can't solve most of the above-mentioned problems, there are certain limitations in the range of activities and the way of movement, and if the elderly use the wheelchair for a long time to travel, due to The inability to stretch the body will affect the blood circulation, causing the legs to feel cold or even swollen. At the same time, it will compress the lumbar spine and cause more damage

[0005] However, the use of crutches is too small, and it still needs to consume a lot of physical strength and work of the user.

[0006] However, devices such as elevators or handrails in the stairwell are expensive and have strong limitations. They are only suitable for going up and down the stairwell, and the handrails only serve to prevent falls, which cannot greatly facilitate the elderly to go up and down the stairs.
