Abstract

The invention belongs to the pneumatic technology field, and relates to pneumatic artificial muscle. The artificial muscle consists of an outer mesh grid, an inner expansion tube, a sealing component and a sealing component with air vents. The outer mesh grid is aligned with the inner expansion tube at two ends and sleeved on the inner expansion tube, with the original length thereof a little longer than that of the inner expansion tube; and one end of the outer mesh grid is inserted into the sealing component, and the other end thereof is inserted into the sealing component with air vents. The inner expansion tube of the pneumatic artificial muscle is inflated with air with a certain pressure, so that the inner expansion deforms to cause the outer mesh grid to expand in the radial direction, so as to enable the pneumatic artificial muscle to expand in the radial direction, contract in the axial direction and output certain tensile force. The pneumatic artificial muscle has the characteristics of compact structure, simple manufacture, low price, high flexibility, high ratio of output force to dead weight, effective energy conservation, automatic buffer, pollution resistance, etc., and can be widely applied to the fields of robots, auxiliary medical apparatus and instruments, aviation, defense industry, etc.

Description

technical field

[0001] The invention relates to a pneumatic artificial muscle, in particular to a novel pneumatic artificial muscle controlled by compressed air, belonging to the technical field of pneumatics. Background technique

[0002] The prosthetic products (bionic arms, bionic legs) currently designed for the disabled are either complex in structure and expensive, or similar in appearance to the human body but simple in function and impractical. One of the main reasons for this phenomenon is that most bionic arms and bionic legs use motors as drivers. The characteristics of heavy weight and relatively low output power of the motor limit its application in prosthetic products. Pneumatic artificial muscle is an actuator with characteristics similar to biological muscles, which helps to promote the development of prosthetic products in the direction of functional humanoid.

[0003] With the advent of an aging society, nursing robots are undoubtedly a boon for society. ...
