Power device for wearable power-assisting exoskeleton

Abstract

The invention relates to a power device for a wearable power-assisting exoskeleton. The power device for the wearable power-assisting exoskeleton comprises a coil spring shell, wherein an opening is formed in the coil spring shell; a coil spring is located in the coil spring shell; the outer end head of the coil spring is hooked on the opening; shell covers are arranged on two sides of the coil spring shell; bearings are arranged in the centers of the shell covers; a pressing cover is arranged on the coil spring shell; a pull wire winds on the outer circumference of the coil spring shell; theend head of the pull wire is fixedly pressed on the coil spring shell through the pressing cover; the coil spring shell is located in a shell formed by a shell and a shell cover; a connecting seat isfixedly clamped between the shell and the shell cover; a connecting pipe is connected onto the connecting seat; a nut is connected to the upper end of the connecting pipe; the pull wire penetrates through the connecting seat, the connecting pipe and a nut center hole; an installation plate and a connecting plate are fixed onto the shell and the shell cover; a coil spring shaft is inserted into thecenter holes of the shell and the shell cover; the middle part of the coil spring shaft is inserted into bearing inner holes; the inner end head of the coil spring is inserted into a longitudinal groove on the coil spring shaft; one end of the coil spring shaft stretches to the outer side of the shell; a ratchet is arranged on the outer end head of the coil spring shaft; a pawl matched with the ratchet is rotatably connected onto the outer side surface of the shell; and a moving handle is connected to one end of the pawl.

Description

technical field [0001] The invention relates to a power device for a wearable power-assisted exoskeleton, which is a driving device in a device that uses an elastic element to provide support for a human arm. Background technique [0002] At present, traditional passive shoulder-assisted exoskeleton equipment includes a wearing part, a supporting part, an arm mechanism and an elastic driving device. Wearing part is made up of belt, shoulder belt, braces etc., and the main component of supporting part is strut, and the lower part of strut is connected with the rear part of belt, and arm mechanism and elastic driving device are installed on the upper end of strut. The elastic driving device of the passive shoulder assist exoskeleton equipment is mostly placed on the shoulder of the wearer due to structural reasons. The pull wire in the driving device is connected to the rotating arm in the arm mechanism, and the elastic force of the pulling wire in the driving device Under th...

Problems solved by technology

The size of the driving device makes the shoulder device have the possibility of scratching, which not only damages the exoskeleton itself, but also poses a safety hazard to other equipment in the production environment
