Abstract

The invention discloses an active drawstring type upper limb assisting exoskeleton. The active drawstring type upper limb assisting exoskeleton comprises a back supporting assembly, a bearing assembly, a driving mechanism and a drawstring cantilever mechanism, the back supporting assembly is arranged on the rear side of the bearing assembly, the driving mechanism is arranged on the back supporting assembly, the drawstring cantilever mechanism comprises two cantilevers, and the two cantilevers are symmetrically arranged in the horizontal direction of the back supporting assembly; and a pull belt and a belt wheel are contained in the two cantilevers respectively, one end of the pull belt is wound on the belt wheel, the other end of the pull belt is hung on one side of the bearing assembly along the cantilevers and provided with a hook, a rotating shaft is arranged between the two cantilevers in a penetrating mode, the belt wheel is fixedly arranged on the rotating shaft, and the driving mechanism is arranged on the back supporting assembly and is in power connection with the rotating shaft. The driving mechanism drives the rotating shaft to rotate and drives the pull belt winding the belt wheel to take up and pay off, so that the load on the hook is driven to lift. According to the active drawstring type upper limb assisting exoskeleton, the load is lifted through the drawstring of the drawstring cantilever mechanism, the upper limbs of a human body can be effectively replaced to exert force, the efficiency is high, and a user is not prone to being hurt.

Description

technical field [0001] The present invention relates to the technical field of human body wearable devices, in particular to an active pull belt type upper limb power-assisted exoskeleton. Background technique [0002] An exoskeleton is a wearable mechanical device that can provide assistance to the human body. Rigid materials are used as inter-joint supports, and electric and hydraulic power units are used as joint drives. During the work process, the power joints are used to provide assistance to the human body and jointly complete the work. target job. The upper limb assisting part of the existing exoskeleton has the problems of complex mechanism, heavy weight, low reliability, limited assisting effect, and poor human-machine compatibility. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an active pull-belt type upper limb power-assisted exoskeleton that can solve the problems in th...
