Multi-stage energy-storage assistant exoskeleton

Abstract

The invention discloses a multi-stage energy-storage assistant exoskeleton, and belongs to the field of medical rehabilitation apparatuses. The assistant exoskeleton comprises a calf supporting structure, a spring energy-storage assisting structure and a leg control switch structure, wherein a calf supporting plate piece on the calf supporting structure is connected to a foot bottom supporting plate piece by virtue of a foot movable shaft; and by setting the calf supporting structure, people can wear the assistant exoskeleton conveniently and simply. The spring energy-storage assisting structure comprises a supporting panel, a gear conveying device and a spring energy-storage device; the gear conveying device comprises a rack plate and a gear; the spring energy-storage device is arranged below the rack plate, and the spring energy-storage device comprises a spring sleeve, a spring which is arranged in the spring sleeve and a piston part which is arranged at the upper part of the spring sleeve; the foot control switch structure comprises a foot supporting panel, a rubber slot and a spring switch; and the spring switch is fixed to the foot supporting panel. The multi-stage energy-storage assistant exoskeleton is simple in structure, simple and convenient to wear and is capable of assisting a leg in normal walking; the problem that energy is stored without bouncing when a user takes a step and the energy is released for assisting when the user moves forwards is solved.

Description

technical field [0001] This patent relates to a multi-stage energy storage assisted exoskeleton, which belongs to the category of medical rehabilitation equipment. Background technique [0002] At present, the travel problems of the disabled and people with inconvenient walking are becoming more and more obvious, especially the aging problem is aggravated, and the demand for convenient walking aids is obvious. Most of them use materials to simulate cushioning, or simply support them to meet the walking needs of disabled people. However, energy storage is used intensively in the field of sports for the disabled. Prosthetic limbs with high energy storage, due to their high elasticity and toughness, have extremely strong elasticity at each step and are not suitable for normal walking. Especially middle-aged and elderly people with disabilities or normal people, prosthetics or wearable exoskeletons need a mechanical structure considered from the perspective of normal walking to...
