Boost joints, support legs and exoskeletons

Abstract

The invention discloses a power-assisted joint, which comprises a joint seat, on which a rotating shaft cooperating with the joint seat and a power-assisted driving mechanism for driving the rotating shaft to rotate relative to the joint seat are arranged; wheel and a power mechanism for driving the driving wheel; a rotation limiting structure is provided between the rotating shaft and the driving wheel, and the rotating limiting structure is used to limit the angle range in which the rotating shaft can rotate freely relative to the driving wheel, so as to facilitate collection at the initial stage. The user's walking data. The invention also proposes a power-assisted supporting leg and a power-assisted exoskeleton, which can make the rotating shaft freely rotate within the angle range limited by the rotation limiting structure, that is, there is a turning margin between the rotating shaft and the driving wheel, and the user can The legs can be used to drive the rotating shaft to rotate freely relative to the driving wheels, so that the user's walking data can be obtained and the user's walking intention can be predicted, so that the power-assisted driving mechanism can be conveniently used to provide power assistance.

Description

technical field [0001] The invention relates to an exoskeleton, in particular to a power-assisted joint, a supporting leg and an exoskeleton. Background technique [0002] In some scenarios where traditional wheeled vehicles are difficult to apply, human or animal power is often required to carry objects. For example, when porters carry goods up and down stairs, when scientific research and firefighters work in the field, and when soldiers walk with heavy loads in mountainous areas, they all need to carry heavy loads for long-distance walking. Excessive loads will cause certain damage to the human body. In addition, as the global aging problem becomes more and more serious, exoskeletons can help some elderly people to solve the problem of poor physical strength and unchanged walking, and help some people who have lost their mobility to recover part of their mobility. [0003] The characteristic of the power-assisted exoskeleton is that it requires collaboration with the wea...

AI Technical Summary

Problems solved by technology

Existing power-assisted exoskeletons generally have a complex power-assisted system, and the power-assisted system first needs to collect data to predict the walking movement of the human body in order to provide assistance, and when the first step of walking is started, the power-assisted system cannot predict the walking direction and movement of the human body At this time, it is generally necessary for the human body to overcome the resistance of the power assist system to perform walking movements before providing power assistance. This is a great burden for the elderly who have difficulty walking or people who are tired from walking for a long time, and even lead to walking failure because they cannot take the first step The problem
