The course of work of the invention is as follows:
User dresses ectoskeleton, according to the body sizes of wearer, adjusts the width of hip joint, the length of thigh and calf,
Ensure the joints axes section of human body just to the joints axes of ectoskeleton.Back as human body rear waist, backboard by bandage carry on the back in
Back, sole is connected with human foot.
When user carries out lower limb rehabilitation to move, hip joint hydraulic cylinder control hip joint flexion/extension mechanism, before completing thigh
After swing, knee hydraulic cylinder control knee flexion/extension mechanism completes the swing of knee.Leg needs lateral lift when user walks
During leg, with human motion, when needing to turn, hip joint medial rotation/Xuan Wai mechanisms transport with human body for the interior receipts/abduction mechanism of hip joint
It is dynamic.When the inclined ground of out-of-flatness is run into, the outer abduction/adduction mechanism of ankle-joint slightly rotation adapting to the angle on ground, bullet
Property steel plate play Auxiliary support effect.The sole bent in hinge laminating motion at sole.
