The invention discloses a wearable lower extremity
exoskeleton power-assisted
robot. The wearable lower extremity
exoskeleton power-assisted
robot comprises a back frame, hip joints,
thigh assemblies, calf assemblies,
knee joint sleeves,
ankle joints and shoe soles. The front side of the back frame is provided with hip joint protective plates. The hip joints are installed on the two sides of each hip joint protective plate. The upper ends of the
thigh assemblies are connected with the hip joints, and the lower ends of the
thigh assemblies are connected with the upper ends of the calf assemblies. The lower ends of the calf assemblies are connected with the
ankle joints. The
ankle joints are fixed to the outer sides of the shoe soles. A hip joint hydraulic oil cylinder is installed between each hip joint and the front side of the corresponding thigh
assembly. A
knee joint hydraulic oil cylinder is installed between the rear side of each thigh
assembly and the rear side of the corresponding calf
assembly. A foot hydraulic oil cylinder is installed between the front side of each calf assembly and the corresponding shoe sole. The hip joint hydraulic oil cylinders, the knee hydraulic oil cylinders and the foot hydraulic oil cylinders are controlled to stretch out and draw back by a
hydraulic control system. The wearable lower extremity
exoskeleton power-assisted
robot has the advantages that large loads can be achieved, and
automation can be achieved by controlling oil lines; and the size of all the components of the robot is adjustable, constraint to the hip joints is reduced after a soldier wears the robot, and the robot meet the principle of man-
machine engineering better.
