Hydraulic damper for exoskeleton orthosis device

Abstract

The invention relates to the technical field of orthosis devices, in particular to a hydraulic damper for an exoskeleton orthosis device. The hydraulic damper comprises a piston cylinder and a proportional valve, wherein a first oil cavity and a second oil cavity are formed in the piston cylinder, a first piston is arranged in the first oil cavity and is connected with a piston rod, a second piston is arranged in the second oil cavity and is connected with a spring, the spring is connected with the inner wall of the second oil cavity, and the proportional valve is arranged between a first oil way and a second oil way. The hydraulic damper is matched with a walking state of a human body through telescopic movement of the piston rod in the piston cylinder, and the telescoping rate of the piston rod in the piston cylinder is adjusted through the proportional valve, so that piston movement of the piston rod in the piston cylinder can be passively matched with the walking state of the human body, adjustment is performed at any time according to the walking speed of a user, it is kept that the human body walks freely to the most degree, and the stability is ensured.

Description

technical field [0001] The invention relates to the technical field of orthotics, in particular to a hydraulic damper for an exoskeleton orthosis. Background technique [0002] Human lower extremity exoskeleton orthosis is a wearable mechanical assist device, mainly used in the military and medical fields. In the military field, it is used to assist soldiers to carry weapons that exceed the human body load. Apparatus to assist patients in their rehabilitation. Therefore, based on the above applications, the lower extremity exoskeleton orthosis needs to be flexible, comfortable to wear, and light in weight. After wearing the exoskeleton orthosis, it can assist the human body to walk, or the human body can walk under overload. [0003] Existing lower extremity exoskeleton orthoses usually use motors and hydraulic cylinders to adjust and control the orthosis, wherein the motor drives the turntable to rotate, and then pushes the piston to reciprocate in the hydraulic cylinder t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a hydraulic damper for exoskeleton orthosis, which solves the problems in the prior art that the motor drives the hydraulic cylinder to force the human body to walk when the piston moves, which easily causes the center of gravity to be unstable and the walking posture to be stiff
