Abstract:
PURPOSE: A link cylinder actuator and a wearable robot including the same are provided to enable a wearable robot to perform work and to minify the structure of the wearable robot by integrating a driving device and a link. CONSTITUTION: A link cylinder actuator and a wearable robot comprise an upper link(10) and a lower link(40). The upper link comprises an upper piston(15) and an upper crank rod(13). The upper piston is equipped with an upper piston rod(16) which is projected towards an upper crank(11) and is mounted inside a tube which has a hollow inside. The upper crank rod is rotatably combined to the end of the upper piston rod and is eccentrically and rotatably combined to the lower crank surface of the lower link. The lower link comprises a lower piston(45) and a lower crank rod. The lower piston is equipped with a lower piston rod(46) which is projected towards a lower crank(41) and is mounted inside the tube which has the hollow inside. The lower crank rod is rotatably combined to the end of the lower piston rod and is eccentrically and rotatably combined to the upper crank surface of the upper link.
Abstract:
PURPOSE: A wearable exoskeleton device for assisting muscular strength is provided to be easily unfolded or folded using a small amount of power by enabling the control of elastic force. CONSTITUTION: A wearable exoskeleton device(100) for assisting muscular strength comprises lower and upper links(10,40), first and second vertical links(20,30), an extensible drive unit(70), and an elastic member(50). The first vertical link rotatably couples one ends of the lower and upper links to each other, and the second vertical link rotatably couples the other ends of the lower and upper links to each other. The extensible drive unit is installed on one of the facing surfaces of the lower and upper links. One end of the elastic member is movably coupled to the extensible drive unit, and the other end is fixed to one of the lower and upper links which does not have the extensible drive unit.
