Abstract

The invention provides a bending joint of a finger rehabilitation device based on double pneumatic flexible actuators. The bending joint comprises two pneumatic flexible actuators with identical structural parameters, a T-shaped structure and two rotational structures, wherein the two rotational structures are arranged on the T-shaped structure through rotating shafts to form a rotation pair, front end covers and rear end covers of the pneumatic flexible actuators are respectively fixed on the T-shaped structure and the rotational structures, and axes of the two pneumatic flexible actuators are parallel to each other and perpendicular to the rotating shafts simultaneously. The bending joint is simple in structure, and good in flexibility and applicability.

Description

technical field [0001] The invention relates to a bending joint, in particular to a bending joint for a pneumatic flexible finger rehabilitation device. Background technique [0002] The human hand is the most frequently used body part in human daily life, and the incidence of hand motor function loss and its complications caused by accidents or other diseases has always been high. At the same time, rehabilitation nursing after hand trauma and functional recovery training for patients with limb hemiplegia caused by brain injury all require passive exercise rehabilitation training with the help of equipment to achieve the best rehabilitation effect. Based on the structure of human finger joints, the designed finger rehabilitation device mainly completes the following tasks: continuous joint bending action, which drives the finger joints to bend, so as to realize rehabilitation training. It can be seen that the performance of the bending joint directly determines the final ef...
