Problems solved by technology

However, most of the existing knee support devices are active and rigid components, which will inevitably lead to problems such as excessive device mass, poor battery life, complicated electrical circuit layout, and low fault tolerance. Most of the devices use springs to provide support, but it is difficult for springs to meet the range of motion required in the squatting process, and it is difficult to keep the support stable

Embodiment Construction

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, the descriptions involving "first", "second" and so on in the present invention are only for descriptive purposes, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the technical solutions of the various embodiments can be combined with each other, but it must be based on the realization of those ski...

Abstract

The invention discloses a knee joint passive reconstructable submissive constant force assisting device. The device comprises a first cylinder body and a second cylinder body, the first cylinder bodyis sleeved with the second cylinder body, a calf supporting plate is fixedly arranged on the outer surface of the first cylinder body, a thigh supporting plate is fixedly arranged on the outer surfaceof the second cylinder body, a ratchet wheel shaft is fixedly arranged in the center of the bottom of the inner wall of the first cylinder body, the ratchet wheel shaft is sleeved with a rotary sleeve, the rotary sleeve is fixedly connected with the second cylinder body, a submissive unit is arranged on the outer surface of the rotary sleeve, the submissive unit comprises a plurality of submissive sheets, the submissive sheets overlap in the axial direction of the ratchet wheel shaft, the submissive sheets comprise friction rings and elastic supporting frames, the inner walls of the frictionrings fit the rotary sleeve, multiple elastic supporting frames are arranged on the outer surfaces of the friction rings in circular arrays, baffle blocks which fit the elastic supporting frames are fixedly arranged on the inner wall of the first cylinder body, and multiple baffle blocks are arranged in spiral array taking the ratchet wheel shaft as the center. The invention provides a solution scheme in which bearing is sequentially conducted in a multi-stage submissive sheet manner and supporting force is provided by the characteristics of a submissive device.

Description

technical field [0001] The invention belongs to the technical field of human body assisting machinery, and in particular relates to a passive, reconfigurable, compliant and constant force assisting device for a knee joint. Background technique [0002] With the development of advanced manufacturing, more convenient and effective human body assisting devices are widely used in people's daily life. As an important load-bearing part of the leg, the knee joint is one of the focuses of human body assist device research, especially with the aging of the population and the changes in the way people live and work in modern cities, knee joint injuries and the resulting lesions and auxiliary The proportion of recovery needs is increasing year by year, and the prevention of knee joint injuries is also more and more valued by people. Therefore, the design and development of knee joint protection and power-assisted devices have attracted extensive attention from domestic and foreign scho...
