Pneumatic muscle

A pneumatic muscle, fibrous membrane technology, applied to pneumatic muscles. It can solve the problems of increasing the fiber membrane thickness and deformation resistance of the sidewall of the pneumatic muscle, reducing the overall driving performance and response speed of the pneumatic muscle, and shortening the durability of the pneumatic muscle, so as to improve the driving performance, improve the durability, and reduce the heat loss.

Problems solved by technology

[0003] At present, there have been aerodynamic muscle schemes that use shape memory alloy wires to promote the bending and torsional degrees of freedom of aerodynamic muscles, and the shape memory alloy wires are separated from the elastic rubber tubes and braided mesh of the aerodynamic muscles by heat-insulating glue, but the thermal insulation is applied Glue will increase the thickness and deformation resistance of the fiber membrane on the side wall of the aerodynamic muscle, resulting in a decrease in the overall driving performance and response speed of the aerodynamic muscle, and the heat loss of the part where the fiber membrane is in direct contact with the shape memory alloy wire will be significantly higher than other parts of the fiber membrane , which shortens the durability of the pneumatic muscle

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, a pneumatic muscle includes a fiber membrane 2 with openings at both ends, the two ends of the fiber membrane 2 are provided with a sealing member that is sealingly connected to the opening of the fiber membrane 2, and the inside of the fiber membrane 2 is provided with at least A shape memory alloy wire 3, the two ends of the shape memory alloy wire 3 are respectively fixedly connected to the sealing member and the angle between the shape memory alloy wire 3 and the axis line of the fiber membrane 2 is greater than 0° and less than 90° °.

[0023] When the shape-memory alloy wire 3 in the inner cavity of the pneumatic muscle undergoes a phase transition through current C, the shape-memory alloy wire 3 becomes shorter so that the pneumatic muscle actively generates contraction driving force, and the hea...

Abstract

The invention belongs to the technical field of robot driving, and relates to a pneumatic muscle. The pneumatic muscle comprises a fiber film having opening parts at two ends; sealing components tightly connected with the opening parts of the fiber films are arranged at two ends of the fiber films; at least one shape memory alloy wire is arranged in the fiber film; the two ends of the shape memory alloy wires are fixedly connected with the sealing components, respectively; and included angles betwen the shape memory alloy wires and the axis of the fiber films are bigger than 0 degree and smaller than 90 degrees. The pneumatic muscle is high in durability and fast in response speed.

Description

technical field [0001] The invention belongs to the technical field of robot driving and relates to a pneumatic muscle. Background technique [0002] With the rapid development of robotics, pneumatic muscles, as a high power-to-weight ratio, clean and pollution-free drive, have been widely used in the field of robotics. [0003] At present, there have been aerodynamic muscle schemes that use shape memory alloy wires to promote the bending and torsional degrees of freedom of aerodynamic muscles, and the shape memory alloy wires are separated from the elastic rubber tubes and braided mesh of the aerodynamic muscles by heat-insulating glue, but the thermal insulation is applied Glue will increase the thickness and deformation resistance of the fiber membrane on the side wall of the aerodynamic muscle, resulting in a decrease in the overall driving performance and response speed of the aerodynamic muscle, and the heat loss of the part where the fiber membrane is in direct contac...
