Knee joint guide apparatus

Abstract

Disclosed is a knee joint guide apparatus which can be driven even at any point on a plane in which an instantaneous rotation center of a knee joint can be positioned by a self-alignment function, and can also implement output performance required for a walking operation through a mechanical advantage change depending on a flexion angle. The knee joint guide apparatus includes: a proximal body link provided above a knee joint; a distal body link provided at a location corresponding to the proximal body link below the knee joint; and a planar rigid body 6-bar linkage mechanism including a plurality of revolute joints and a plurality of prismatic joints, and a plurality of links between the proximal body link and the distal body link to output a mechanical advantage depending on a flexion angle of the knee joint in movement of the knee joint with a self-alignment function.
