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

Embodiment 1

[0024] see figure 1 and figure 2 , the labor-saving walking aid without external power input, comprising a walking aid body (I), a connecting kit (II), a ratchet mechanism (III) and an energy storage torsion spring (IV), characterized in that: the walking aid The front part of the shoe body (15), the rear part of the shoe body (1), and the rear bottom of the shoe body (6) in the main body (I) are concentrically connected through the corresponding connecting shafts; Shaft (5), central shaft (9), ratchet shaft (12), and front shaft (13) are concentrically connected to each component in the walker body (I); the anti-reverse ratchet in the ratchet mechanism (III) The claw (10) is engaged with the special-shaped ratchet (11) in different travel states, and is stopped by the control device; the torsion spring (19) in the energy storage torsion spring (IV) is fixedly installed on the circumferential position of the ratchet shaft (12) , so as to store the kinetic energy when the an...

Embodiment 2

[0026] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0027] The walking aid body (I) includes the front part of the shoe body (15), the rear part of the shoe body (1), the shoe buckle (17), the rear bottom of the shoe body (6) and the buffer rubber pad (7, 14), wherein The front part of the shoe body (15) is connected to the rear part of the shoe body (1) in a hinged manner through the front axle (13) installed on it, and the shoe buckle (17) is connected to the rear part of the shoe body (1) through the fixing block (2) connection, the buffer rubber pads (7, 14) are respectively adhered to the back sole (6) of the shoe body (6) and the front part of the shoe body (15) by means of gluing; the walking aid body (I) adopts an aluminum base unless otherwise specified. It can guarantee to bear the weight of the human body, and the variable rubber of the buffer pad and the sponge insole of the insole can make the user comfortable t...

Embodiment 3

[0032] Such as figure 1 , 2 As shown, this labor-saving walker without external power input includes a walker body I, a connection kit II, a ratchet mechanism III, and an energy storage torsion spring IV. It is characterized in that: the walker body (I) includes a shoe Body front part (15), shoe body rear part (1), shoe buckle (17), shoe body rear bottom (6) and buffer rubber pad (7, 14), wherein the shoe body front part (15) is installed on its The upper front axle (13) is connected to the rear part of the shoe body (1) in a hinged manner, the shoe buckle (17) is connected to the rear part of the shoe body (1) through the fixing block (2), and the cushion rubber pads (7, 14) pass through The cementing method is respectively adhered to the rear bottom of the shoe body (6) and the front part of the shoe body (15).

[0033] The connection kit (II) includes a fixed block (2), a sleeve (3), a T-shaped connecting rod (4), a rear axle (5), a middle axle (9), a ratchet axle (12), a...

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....
