Problems solved by technology

The advantages of the motor drive system are high efficiency, precise control, and easy installation, but its low efficiency-to-mass ratio makes it difficult to achieve wide-scale use in exoskeletons
The advantage of the hydraulic system is that it has a large power-to-mass ratio and can generate large thrust in a small volume; however, the hydraulic system uses hydraulic oil as the working medium, which is prone to leakage problems; and the hydraulic drive system has low efficiency and consumes a lot of energy. High requirements, high processing requirements, high cost
The pneumatic system has the advantages of clean working medium, high efficiency, light weight, and low cost, but it is difficult to apply to high-power systems due to the low power-to-mass ratio of cylinder components

Abstract

The invention discloses a pneumatic muscle upper limb assistance exoskeleton system which comprises a back arm bone, an upper arm bone, a front arm bone, a shoulder side direction skeleton and a shoulder front direction skeleton. The upper end of the back arm bone is connected with the shoulder side direction skeleton through a first joint module, and the back arm bone is connected with the shoulder side direction skeleton through a pneumatic muscle used for driving the first joint module to move; the upper end of the upper arm bone is connected with the shoulder front direction skeleton through a second joint module, and the upper arm bone is connected with the shoulder front direction skeleton through a pneumatic muscle used for driving the second joint module to move; the front arm bone is connected with the upper arm bone through a third joint module, and the front arm bone is connected with the upper arm bone through a pneumatic muscle used for driving the third joint module to move; and the upper arm bone and the front arm bone are each provided with a pressing ring. According to the pneumatic muscle upper limb assistance exoskeleton system, the pneumatic muscles are adopted as execution elements, and a user and the exoskeleton system have good interoperability.

Description

technical field [0001] The invention relates to the technical field of mechanical exoskeleton products, in particular to a pneumatic muscle upper limb assisted exoskeleton system. Background technique [0002] Mechanical exoskeletons are human-oriented robots, which can be defined as those devices worn by users that supplement or replace limbs. An exoskeleton can be steered on one side of the user's limb, coordinating movement with the user's limbs, or replace a part of a disabled user's limb and cooperate with the remaining limbs; but this does not necessarily mean that the exoskeleton must be Movable or portable, a large part of the reason is the limitation of the volume and weight of actuators and power sources; mechanical exoskeleton can be regarded as a technology that enhances, adapts, and protects the wearer's body. The exoskeleton can expand the user's ability on the basis of the user's manipulation, helping the user achieve strength beyond his own; it can also help...
