Problems solved by technology

Therefore, there is a part of the gas inside the artificial muscle that does not circulate. When the artificial muscle reciprocates for a long time, the temperature of this part of the gas will gradually increase, which seriously affects the service life of the artificial muscle.

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in Figure 1, a double-opening straight fiber type soft joint artificial muscle includes an inner layer of rubber tube 4, a straight fiber 3 arranged axially outside the inner layer of rubber tube 4, located at both ends of the inner layer of rubber tube 4 and connected to the inner layer of rubber tube 4 The end of the straight fiber 3 is integrated with the fixed line 1. The straight fiber 3 wraps the part of the inner rubber hose 4 between the two ends. 7 is tightly wound to form a catheter, and an end compression wire 6 is wound outside the inner rubber tube 4 near the fixed wire 1. The straight fiber 3 is made of hard material. The straight fibers 3 are made of soft materials, the outer rubber hose 2 is arranged outside the inner rubber hose 4 , and the straight fibers 3 are arranged between the inner rubber hose 4 and the outer rub...

Abstract

The invention discloses double-opening straight fiber type soft-joint artificial muscle. The artificial muscle comprises an inner rubber tube, multiple straight fibers, an anti-deformation line, end fixing lines and sealing end press lines, wherein the multiple straight fibers are arranged on the outer side of the inner rubber tube in an axial direction; the anti-deformation line transversely constrains the straight fibers in the middle; the end fixing lines are located at two ends of the straight fibers and integrated with the straight fibers; the sealing end press lines are located at the two ends and used for transversely constraining the straight fibers; the middle part of the inner rubber tube is wrapped with the straight fibers; the part, which is not wrapped with the straight fibers, of the inner rubber tube is tightly wound with external pressure-bearing tightening lines, and a catheter is formed; and each sealing end press line is adjacent to the corresponding end fixing line so as to wind the straight fibers around the inner rubber tube. The artificial muscle is connected more smoothly and softly and is not prone to damage, and muscle and a driving object can be flexibly connected.

Description

technical field [0001] The invention relates to a driving artificial muscle used in the fields of robots, rehabilitation medical equipment, special operation manipulators and automatic production lines, in particular to a fully soft double-opening straight fiber type soft joint artificial muscle. Background technique [0002] Artificial muscles have a large ratio of output force to mass. Artificial muscles are widely used in medical rehabilitation equipment and robot joint drives. After the artificial muscle is filled with a certain pressure of gas, it contracts axially and expands radially to generate contraction force. Traditional artificial muscles consist of three parts, joints at both ends, inner rubber tubes and straight fibers on the outer side. The connection of the joint part of the artificial muscle mainly depends on the friction between the joint and the straight fiber and the rubber tube. Most of the existing artificial muscles have a single opening, that is, o...
