Labor-saving walking aid without external power input

Abstract

The invention provides a labor-saving walking aid without external power input. The labor-saving walking aid without external power input comprises a walking aid body, a connecting kit, a ratchet mechanism and an energy storing torsional spring. The labor-saving walking aid can be worn on two feet of a user, energy used for doing negative work in the human body walking process is stored and released when positive work is done, and then external power input free type assisting is achieved. Meanwhile, the exoskeleton dead weight is reduced on the basis of optimized structure design, and the exoskeleton flexibility and the people walking efficiency are improved. In addition, any state stopping of the user in the walking process is achieved by applying the non-return ratchet mechanism, therefore, the walking aid locks the energy when the user is static, the design purposes of storing energy and saving labor are achieved, and the stability and the controllability of the device are greatly improved. According to the novel exoskeleton wearing mode, the portability and the practicability of the product are enhanced.

Description

technical field [0001] The invention relates to a labor-saving walking aid without external power input, which belongs to the field of walking aids. Background technique [0002] At present, the main way to travel with heavy loads is still the traditional wheeled vehicle, which has high requirements on the road environment and other fields, such as military, scientific research, fire rescue and other fields, which still cannot be effectively used. Under special circumstances, soldiers, scientific expedition personnel and fire rescue personnel often need to perform tasks such as long-distance walking, carrying heavy objects, transporting injured persons, field operations, mountaineering expeditions, etc. At this time, they cannot use traditional means of transportation Finish. [0003] Based on the above special needs, it is very necessary to design a mechanism that can provide assistance for the wearer to reduce energy consumption during walking and enhance walking ability....

Problems solved by technology

[0004] In Van L. Phillip's patent on the energy storage and release device of the prosthesis, the C-shaped elastic element is mainly installed at the calf prosthesis, so that the human body can use the elastic force of the elastic element to assist the user during movement, but the elasticity alone The component cannot lock energy when it is at rest, and it is very easy to rebound in this state, resulting in difficult device control and instability

[0005] In Keahi Seymour's invention of ostrich spring-assisted bionic boots, although a linear spring is used as an energy storage element during movement, the additional height of the overall device makes it difficult for the user to control when stationary, and also has no energy The locking device makes the power assist system still unstable

[0006] Among the exoskeleton power-assisted devices that are available today, they are generally bulky and heavy due to too many mechanical parts, accompanied by unavoidable noise, and the price is also relatively expensive
