In a joint assembly of a walking assistance robot that is capable of performing an operation with 3 degrees of freedom, similarly to a user's joint, a rolling motion and a sliding motion are simultaneously made, and a rotation center changes so that the joint assembly can make a similar motion to that of an actual knee joint of the user. Thus, when the user wears the walking assistance robot and walks, misalignment can be prevented from occurring in the knee joint.

Joint assembly and walking assistance robot

A walking assistance apparatus for preventing offset occurring in between a rotating axis of a hip joint of a user and a rotating shaft of the walking assistance apparatus may be provided. The walking assistance apparatus includes a waist fixing apparatus configured to be fixed to a waist of a user, a connecting guide mounted at the waist fixing apparatus and configured to slide in an extension direction of the waist fixing apparatus and rotate on a rotating shaft extending in a vertical direction perpendicular to the extension direction, a rail unit mounted at one side of the connecting guide, the rail unit extending in a vertical direction, and a hip joint configured to slide along the rail unit.

Walking assistance apparatus

A frame configured of a plurality of links pivotally connected to one another is flexibly bent, and pins that connect the plurality of links that constitute the frame are inserted into and slide in a curve-shaped slot and a slot in a vertical direction so that, even though the frame is bent, the entire length of the frame is increased and ends of the frame can be moved along a straight line that is horizontal with respect to the ground.
