Problems solved by technology

[0005] However, the current research results have problems such as complex mechanism, inflexibility, and lack of flexibility. At the same time, because the rotation center of the mechanism is inconsistent with the motion center of the human hand, the user is not comfortable enough to wear, and there are also problems in force sense and position measurement. imprecise problem

Abstract

The present invention provides a hand exoskeleton device driven by a pre-bent elastic wire tube, comprising a thumb motion assembly, a thumb drive assembly, a four-finger motion assembly and a four-finger drive assembly, wherein the thumb drive assembly is rotatably connected to the the thumb motion assembly and drive the thumb motion assembly to bend, stretch and swing, the four-finger motion assembly is connected to the four-finger motion assembly and drives the four-finger motion assembly to bend and stretch, the thumb actuation assembly rotatably connected to the four-finger actuation assembly, the thumb motion assembly and the four-finger motion assembly are actuated based on a pre-bent elastic wire tube. The hand exoskeleton device according to the present invention can rotate in accordance with the flexion, extension and swing of human fingers, and has strong flexibility.

Description

technical field [0001] The invention relates to the field of human body motion assisting devices, in particular to a hand exoskeleton device driven by a pre-bent elastic wire tube. Background technique [0002] The hand is an important component organ of the human body. Stroke and accidental injury can easily lead to the loss of sensory and motor functions of the human hand, seriously affecting people's daily life. High-intensity continuous rehabilitation training is an effective treatment. Traditional rehabilitation training mainly relies on the experience of doctors, lacks scientificity and systematicness, and has relatively limited therapeutic effects. A hand exoskeleton is a mechanical device fixed to the human hand. The rehabilitation training method based on hand exoskeleton can provide patients with scientific and quantitative treatment according to individual differences of patients through precise force and position control, accelerate the rehabilitation process,...
