Abstract

The invention discloses a semi-active rigid-flexible coupling hydraulic exoskeleton, which relates to a power assist mechanism in the field of robots, comprising: a waist assembly and a leg assembly; Alloy sleeve, cylinder head, piston, extension spring, oil filler plug, staggered channel valve body, valve body seal seat, valve body end bevel gear, angle sensor, motor mount, DC servo motor, coupling and motor Bevel gear. The present invention can realize the power assist or damping adjustment of two modes of carrying heavy objects and walking with load; in the mode of carrying heavy objects, it can support two carrying modes from high to low and from low to high, and the applicability At the same time, it can provide assistance to the knee joint when the knee joint is naturally flexed in a bent state; a semi-active torque adjustment system is formed by a hydraulic damper and a spring, and the assistance and damping force can be adjusted; light weight, strong man-machine coupling .

Description

technical field [0001] The invention relates to a power assist mechanism in the field of robots, in particular to a semi-active rigid-flexible coupling hydraulic exoskeleton. Background technique [0002] my country's transportation industry, logistics industry, construction industry and manufacturing industry have a huge number of employees, and a considerable number of types of work need to perform long-term repetitive operations, resulting in physical fatigue injuries, especially the waist and knees are the most serious. Exoskeleton robot refers to a kind of intelligent wearable device that imitates the state of human motion and enhances the ability of human motion, and integrates bionics and ergonomics. The existing waist and knee assist exoskeletons are divided into two types, namely active assist exoskeleton and passive assist exoskeleton. The active power-assisted exoskeleton assists the upper body movement of the human body or the flexion and extension of the knee j...
