Abstract

A lower limb exoskeleton system includes a back frame, hip joint movement mechanisms, telescopic thigh bars, knee joint movement mechanisms, shank bars, foot jump-down cushioning mechanisms, a waist binding frame, upper leg binding frames and lower leg binding frames. Two protruding ends of the back frame are connected with a top end of each of the telescopic thigh bars respectively via the hip joint movement mechanisms, bottom ends of the telescopic thigh bars are connected with a top end of the corresponding shank bars respectively via the knee joint movement mechanisms, and bottom ends of the shank bars are connected with the foot jump-down cushioning mechanisms. The waist binding frame is arranged on an inner side of a horizontal part of the back frame, and the upper leg binding frames and the lower leg binding frames are arranged on the telescopic thigh bars and the shank bars respectively.
