Hydraulic lasso drive device used for assisting exoskeletons

Abstract

The invention discloses a hydraulic lasso drive device used for assisting exoskeletons. The hydraulic lasso drive device used for assisting the exoskeletons comprises a support, an integration hydraulic actuator, clamp heads and lassos. The integration hydraulic actuator comprises secondary electro-hydraulic servo valves and an integration cylinder body. Piston cavities arranged parallel to one another are arranged in the lower portion of the integration cylinder body. Through holes communicated with the piston cavities are formed in the top end of the integration cylinder body. The through holes at the top end of the integration cylinder body are provided with sealing front end covers. Sealing back end covers are arranged on the bottoms of the piston cavities. A hydraulic actuating unit is arranged in each piston cavity. Each hydraulic actuating unit is corresponding to a secondary electro-hydraulic servo valve, a clamp head and a lasso and comprises a piston rod, a sealing part, a dust proof ring and a piston rod combination seal part. The clamp heads are connected with the bottom ends of the piston rods. The lassos are fixedly arranged on the clamp heads. The hydraulic lasso drive device not only solves the arrangement problem of a complex oil way of a hydraulic drive exoskeleton system, but also overcomes the problem that inertia force of all joints of the exoskeletons is large.

Description

technical field [0001] The invention relates to a hydraulic lasso driving device, in particular to a hydraulic lasso driving device for assisting an exoskeleton. Background technique [0002] An exoskeleton is a mechanical system connected in parallel to the outside of the user's body for assisting, walking or assisting rehabilitation. [0003] Exoskeleton can be used as a power-assisted device for long-distance weight-bearing walkers, and can be widely used in the military. As an individual equipment system, it can reduce the energy consumption of soldiers themselves, improve combat mobility, and enhance the endurance of soldiers. [0004] Similarly, exoskeletons can be applied to post-disaster rescue, and emergency rescuers can also use the lower limbs to assist exoskeletons to carry heavy loads across places that wheeled vehicles cannot reach, such as rubble, debris and rough roads. [0005] In terms of civilian use, furniture movers, construction workers, warehouse kee...
