Power-free lower limb exoskeleton

Abstract

The invention discloses a power-free lower limb exoskeleton. The invention provides an exoskeleton device which can assist in supporting a lower limb of a human body during walking, does not need external power, and has the characteristics of simple structure, convenience in wearing and use and reliability. The power-free lower limb exoskeleton mainly comprises a supporting seat, a thigh part, a shank part, a foot part and a joint locking device; the supporting seat can support the crotch of a person; the upper end of the thigh part is movably connected with the supporting seat through a rod end bearing, and the lower end of the thigh part is rotationally connected with the upper end of the shank part through a shaft pin; the lower end of the shank part is connected with the foot part in a sliding sleeve mode; the joint locking device is installed on the shank part; and the joint locking device is connected with the foot part through an inhaul cable. When the foot part steps on the ground, the shank part and the thigh part are fixed through the foot part and the joint locking device, the weight of the person is transmitted to the ground through the supporting seat, the thigh part and the shank part, and the lower limb is supported in an auxiliary mode.

Description

Technical field [0001] The present invention belongs to the field of human outer skeleton technology, and specifically, there is a lower limb outer bone without a need for power. Background technique [0002] When people walk, the weight of the whole body is affected by the lower limbs. For those who have dysfunction in the lower extremities, walking is a difficult or even painful thing. Many people often need to take a wheelchair or use a crutches. Although there is already there. Electric power-saving outer skeleton mechanism, but it is very difficult to use due to factors such as structural complexity, large weight and limited battery capacity, it is difficult to popularize, so it is necessary to have simple structure, light weight, light weight, wear and use. Skeletal mechanisms to assist lower limbs to protect the pain or dysfunction. Inventive content [0003] The purpose of this technology is to provide a support device that is simple, small, light, light, wearing and use...
