Torsional contraction artificial muscle

Abstract

The invention relates to a soft driver, in particular to a torsional contraction artificial muscle. The torsional contraction artificial muscle comprises an outer packaging layer, a fiber winding andan elastomer, wherein the elastomer is of a hollow structure, and radial expansion and axial contraction are achieved by filling the driving medium into a hollow cavity; the fiber winding is arrangedon the outer surface of the elastomer, the fiber winding is of a spiral structure, and the elastomer is driven to twist through the spiral torsion drive; and the outer packaging layer is arranged on the outer side of the elastomer in a sleeving manner and is used for limiting the axial extension of the elastomer, and can axially contract and radially expand along with the elastomer. The torsionalcontraction artificial muscle is simple in structure and low in preparation cost, is not only suitable for hydraulic driving, but also suitable for pneumatic driving, can provide torsional movement and contraction motion and can be applied to different fields such as pipeline robots and rehabilitation devices.

Description

technical field [0001] The invention relates to a soft body driver, in particular to a twisting and contracting artificial muscle. Background technique [0002] In recent years, the application fields of artificial muscles have become more and more extensive, including medical equipment, rescue devices and auxiliary devices, etc. This is due to the advantages of artificial muscles: simple structure, compared with hydraulic cylinders, cylinders and ball screws: force-to-weight ratio High, high flexibility, light weight, less mechanical parts and low cost. [0003] Referring to molluscs in nature, some of the worms have fibrous structures, and these fiber structures prompt the worms to perform twisting, elongating and contracting movements. According to the existing fiber-reinforced artificial muscle deformation forms: contraction, elongation, bending and twisting elongation, etc. However, torsional movement is a common form of movement in nature. The torsional contraction h...

Problems solved by technology

However, torsional motion is a common form of motion in nature. The current artificial muscle design has not yet appeared in the form of torsional contraction. The motions of torsional elongation and torsional contraction can complement each other. The two are bound in When together, a movement similar to that of a worm crawling can be achieved
