Leg exoskeleton device for assisting old people in moving

Abstract

The invention provides a leg exoskeleton device for assisting old people in moving, and belongs to the technical field of intelligent equipment for assisting old people in daily life. The leg exoskeleton device comprises walking sticks, magnetic attracting mechanisms and a movement variable connecting rod mechanism; and the magnetic attracting mechanisms are matched with shank supporting rods of the movement variable connecting rod mechanism through magnets on the magnetic attracting mechanisms, and the walking sticks are placed under axillas of a user for assisting walking. By analyzing existing human leg movement, the approximate movement law of legs in the natural state is extracted; in the moving process, thighs take the roots of the thighs as the rotating centers, shanks take the roots of the shanks as the rotating centers, in the process that the thighs rotate towards the outer side, the shanks rotate towards the inner side slightly, and the angle is small; and according to the specific situations in different moving states, the movement variable connecting rod mechanism is designed, and thus in the moving process, it can be ensured that the moving state of leg exoskeletons is similar to the moving state of the normal human legs.

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.
