Abstract:
1. A balancing mechanism configured for a robot, the robot having one or more robot arms, comprising: a hollow balancing body comprising an opening; an elastic assembly received in the balancing body; a bracket comprising a fixing portion and two supporting arms, the two supporting arms extending from opposite sides of the fixing portion and rotatably connected with the balancing body, wherein a first direction X axis is defined, a second direction Y axis is defined to be substantially perpendicular to the first direction X axis, and a third direction Z axis is defined to be substantially perpendicular to the first direction X axis and the third direction Z axis, the fixing portion extends along a direction substantially parallel to the second direction Y axis, the two supporting arms extend toward a same side of the fixing portion, each of the two supporting arms is inclined to a direction substantially parallel to the third direction Z axis; and a pulling rod assembly, wherein the pulling rod assembly is received in the balancing body and hinged to the robot arm, one end of the pulling rod assembly resisting the elastic assembly, and an another opposite end of the pulling rod assembly extending out from the balancing body through the opening, and the pulling rod assembly movably assembled with the balancing body via the elastic assembly to make the elastic assembly generate a balancing moment against a gravity moment of the robot arm.
