Upper body chest power-assist mechanism for power-assist exoskeleton robot

Abstract

The invention relates to an upper body chest power-assist mechanism for a power-assist exoskeleton robot. The mechanism comprises a chest armor, a back armor, two axillary braces and two hydraulic cylinder system components, wherein the upper ends of the chest armor and the back armor are connected through elastic connecting bands, and the lower side faces of the chest armor and the back armor areconnected through the two axillary braces together; the back armor, the chest armor and the axillary braces integrally form a waistcoat shape to be worn on the upper body, and the joints of the backarmor, the chest armor and the axillary braces are connected through the elastic connecting bands; the two hydraulic cylinder system components are arranged on the front end face of the chest armor ina left-right symmetric mode, and the structures of the two hydraulic cylinder system components are completely same; each hydraulic cylinder system component comprises an upper hinging support, a hydraulic cylinder and a lower hinging support, and rod end ball bearings are arranged at the two ends of the hydraulic cylinder; and the two ends of the hydraulic cylinder are respectively connected with the upper hinging support and the lower hinging support through pin shafts. When a person lifts heavy things, the mechanism can provide chest supporting and the person can be easier to bend down andget up during lifting the heavy things.

Description

technical field [0001] The invention relates to the technical field of power-assisted exoskeleton robots, in particular to an upper body chest power-assisted mechanism for power-assisted exoskeleton robots. Background technique [0002] The exoskeleton robot system is essentially a wearable human-machine integration system, which is worn outside the operator's body. It is an artificial skeleton and a mechanical mechanism. It also integrates robotics, ergonomics, Control theory, sensor technology, information processing technology and other fields. Exoskeleton robots provide operators with functions such as protection, body support, power assistance, and walking assistance, which greatly improves human weight-bearing capacity and improves human work efficiency. At present, it has broad application prospects in military, medical, disaster relief, industrial manufacturing and construction, etc. [0003] Existing power-assisted exoskeleton devices mainly include upper limb pow...

Problems solved by technology

The Chinese patent with the application number 201711183894.2 discloses an upper limb power-assisted exoskeleton device, which is equipped with straps, shoulder medial joints, shoulder extension joints, lower arm gas-hydraulic drive cylinders, elbow joints, lower arm support frames, straps and shoulder medial The joints are connected by a one-way rotary structure, mainly to enhance the strength of the human arm and improve the ability of the human body to lift heavy objects. It can also protect the arm, but it is obviously insufficient to assist and support the human body when bending over and standing up when lifting heavy objects.
