Human body joint active power assisting structure based on intelligent materials

Abstract

The invention discloses a human body joint active power assisting structure based on intelligent materials. The human body joint active power assisting structure is formed by refining shape memory alloy, the intelligent high polymer material, a piezoelectric material and the elastomer intelligent material into intelligent fibers, a weaving body is in a hollow cylinder shape, and the edge of the weaving body is an intelligent fiber texture. The intelligent fibers comprise warp fiber slivers and weft fiber rings, the transverse direction and the longitudinal direction of the joints of the warp fiber slivers and weft fiber rings are of a crossed weaving embedded structure, the weft fiber rings at the upper and lower ends of the structure are fixed in the mode that the two ends of all the warpfiber slivers are reversely bent by 180 degrees and stacked below, no warp fiber sliver ends protrude out of the upper and lower ends, and smooth transition is achieved. The structure is made into awearable close-fitting garment close to all joints of the human body. The intelligent fibers are controlled to stretch and retract, each warp fiber sliver and the corresponding weft fiber ring generate deformation in different degrees in the warp direction and in the weft direction respectively, and the active power assisting structure can bend in different degrees; meanwhile, the structure drivescommon fabric fibers to stretch and retract to achieve active power assisting.

Description

technical field [0001] The invention relates to the fields of biomedical engineering and robot technology, in particular to an active assisting structure of human body joints based on intelligent materials. Background technique [0002] With the acceleration of population aging and the increase of traffic accidents, the number of human disabilities is also increasing year by year, which makes the problem of helping the elderly and the disabled increasingly prominent. At present, there are bionic prosthetics, bionic prosthetic robots, rehabilitation robots, and exoskeleton robots to help the disabled and weak resume their daily activities. Most of the auxiliary equipment in the prior art utilizes an exoskeleton to be attached to the user's body, and the joints of the exoskeleton are set to have the same rotation axis as the attached joints. [0003] Invention patent CN105213155A discloses a kind of artificial intelligence auxiliary equipment, which controls the exoskeleton b...

Problems solved by technology

[0003] Invention patent CN105213155A discloses an artificial intelligence auxiliary equipment, which controls the exoskeleton assisting movement by transmitting instructions to the exoskeleton booster worn by the user; The misalignment between the pin joint and the axis of the human joint is high, which causes pain and even injury to the recipient

[0004] In the patent CN104869969A, a passive soft exoprotector consisting of multiple flexible connection elements, anchor points, sensors, actuators and some rigid parts is disclosed to assist human body movement, which is based on the exoskeleton booster. Partial flexibility, to a certain extent, improves flexibility, comfort and ease of wearing, but cannot achieve the purpose of active assist
