WEIGHT-SUPPORTING APPARATUS OF A WEARABLE ROBOT FOR LOWER-LIMB REHABILITATION

摘要

The present invention relates to a device for offsetting the weight of a robot tool and, more specifically and a device for offsetting the weight of a robot tool upward and downward, which enables users to be free from the load of the robot tool connected to the legs of users and users to naturally walk training, comprising a robot tool part connected to the legs of users who need training; a supporting frame which is connected to the upper end of the robot tool part; a connection unit which is extended toward the rear side of the supporting frame; a fixing frame which is connected to the connection unit on the opposite side of the supporting frame; a wire which is connected to the connection unit; a pulley which is contacted to the wire on the upper part of the fixing frame; and an elastic unit which is installed on the edge end of the wire and transfers elasticity corresponding to tension pressurized to the wire wherein the elastic unit comprises a length controlling unit to control the length of the wire and a weight unit for controlling the length of a spring in a pre-load state wherein the connection unit is connected to the two points of the fixing frame and accordingly is capable of rotating with respect to the two points as a center axis for rotation.
