Rope drive exoskeleton device

Abstract

A rope-driven exoskeleton device, the rope-driven exoskeleton device includes a driving component, a supporting component, a transmission rope, a first pulley and a rotating arm, the supporting component is connected to the driving component, the first pulley is connected to the supporting component in rotation, and the rotating arm is connected to the second A pulley connection, the transmission rope includes a first end and a second end oppositely arranged, the first end is connected to the driving assembly, the transmission rope extends along the support assembly, the second end is wound around the outer circumference of the first pulley and connected to the rotating arm or the second A pulley is connected; the driving assembly is used to drive the first end to move, so that the second end drives the rotating arm to rotate around the rotation axis of the first pulley. By setting the transmission rope, the entire transmission process is completed by the transmission rope, without the need for rigid structures such as hinges to switch, so the design and practicality of the rigid structure are greatly reduced, thereby effectively reducing the overall mass, making the inertial force small, and the user's time is reduced. The burden on the body is light, which is conducive to long-term wearing and operation.

Description

technical field [0001] The invention belongs to the technical field of exoskeleton assisting, and in particular relates to a rope-driven exoskeleton device. Background technique [0002] For people who need to raise their hands for a long time (such as construction workers, takeaway delivery, express sorting, assembly of automobiles, airplanes, ships, etc.), muscle strain is often caused by a single and repeated daily lifting action, shoulders and hands Muscle soreness affects the work efficiency of the next day. In response to this market demand, major research institutions and companies have begun to design related exoskeleton equipment, which can give the upper limbs of the human body an auxiliary force by means of wearable equipment. [0003] Most of the currently designed upper extremity exoskeletons use rigid structures and gears as power transmission, resulting in excessive mass and excessive inertial force, which puts a large burden on the user's body, while a small ...

[0002] For people who need to raise their hands for a long time (such as construction workers, takeaway delivery, express sorting, assembly of automobiles, airplanes, ships, etc.), muscle strain is often caused by a single and repeated daily lifting action, shoulders and hands Muscle soreness affects the work efficiency of the next day. In response to this market demand, major research institutions and companies have begun to design related exoskeleton equipment, which can give the upper limbs of the human body an auxiliary force by wearing the equipment.

[0003] Most of the currently designed upper extremity exoskeletons use rigid structures and gears as power transmission, resulting in excessive mass and excessive inertial force, which puts a large burden on the user's body, while a small number of exoskeletons use rope drive. There are also most of the rigid connectors, the mass is still large, and it is difficult to wear for a long time
