Wearable muscular strength assisting device and upper arm module thereof

Abstract

The present invention discloses an upper arm module of a wearable muscle strength assisting device, comprising: a base part connected to the body of a wearer and provided corresponding to the upper end part of the upper arm of the wearer; an upper arm part having one end rotatably coupled to the base part about a fixed point, extending to correspond to an upper arm of the wearer, and coupled to the upper arm of the wearer; an elastic body having one end fixedly coupled to a position spaced apart from one end of the upper arm portion in a direction in which the upper arm portion extends; a first link, one end of which is rotatably coupled to the base portion at an action point provided apart from the fixed point, and which is coupled to the upper arm portion so as to guide the other end tomove when the upper arm portion rotates about the fixed point; and a second link rotatably coupled to the other end of the first link at a first point, coupled to the upper arm portion to guide movement of a second point spaced apart from the first point when the upper arm portion rotates about the fixed point, and coupled to the other end of the elastic body at a third point spaced apart from thefirst point and the second point.

Description

technical field [0001] The present invention relates to an upper arm module of a wearable muscle strength assisting device and a wearable muscle strength assisting device including the upper arm module, and more particularly, to an upper arm module for supporting a wearer's upper arm by compensating for a load caused by gravity And a wearable muscle strength assisting device including the upper arm module. Background technique [0002] A wearable robot is a robot that is worn on a specific part of the body or supports a specific part of the body to assist the movement of the body, and is designed to be used for medical treatment, military affairs, or work. In particular, wearable robots for work are designed to prevent injuries and assist muscular strength by reducing the load applied to workers. This wearable robot simulates the wearer's external skeleton, so the core of its technology is to design the joints to have the same motion as the actual motion of the body. [00...

Problems solved by technology

[0004] However, for the traditional wearable muscle power assisting mechanism, for the required torque distribution (Profile), the cam (cam) and the coil (wire) are combined to form the torque distribution, but the combination of the cam and the coil can lead to Assemblability and workability are reduced, and durability is reduced and noise is generated due to friction and sliding between components
