Wearable flexible lower limb assisting exoskeleton

Abstract

The invention discloses a wearable flexible lower limb power-assisted exoskeleton which comprises a flexible garment, an elastic driving device, a Bowden cable driving device, a driving control device, a flexible binding device and a sensing system. The device is used for providing a stable stress anchor point for the device except for the flexible clothes and ensuring the connection stability and the wearing comfort. The elastic driving device is arranged on the front side of a human body and provides buckling assistance for hip joints; the Bowden cable driving device is arranged on the rear side of the thigh and provides assistance for extension of the hip joint; the driving control device is arranged on the back of the flexible garment and used for controlling the whole system and providing driving power. The flexible binding devices are arranged at knee joints of lower limbs of a human body and used for connecting the knee joints; the sensing system is used for recognizing gaits. The hip joint bending and stretching moment is provided for a user in the walking process, the daily walking stability of a person with lower limb dysfunction is improved, and the lower limb walking gait abnormity is corrected and improved.

Description

technical field [0001] The invention relates to the technical field of exoskeleton robots, in particular to a wearable flexible lower limb power-assisted exoskeleton. Background technique [0002] In the current field of rehabilitation, lower limb exoskeleton rehabilitation robots have become a research hotspot. The lower extremity exoskeleton rehabilitation robot is mainly used to assist the rehabilitation of the injured, the congenitally / acquired disabled and the aging population, and promote the recovery of normal functions of patients, thereby reducing social burden and enhancing social development. Among the current lower extremity exoskeleton rehabilitation robots, most of them are rigid exoskeletons, and the weight of rigid exoskeletons is generally large, which will increase the energy consumption of the wearer as an additional burden. At the same time, the rigid mechanism will limit the freedom of movement of the joints, thereby changing the wearer's natural gait p...
