Servo motor lower limb exoskeleton rehabilitation robot

Abstract

The invention discloses a servo motor lower limb exoskeleton rehabilitation robot. According to the invention, a domestic servo motor and a domestic speed reducer are adopted, so that while the flexible movement of the exoskeleton is achieved, the cost of the exoskeleton is greatly reduced, and when a fault occurs, the maintenance cost is lower. Meanwhile, the defects that a traditional lower limbrehabilitation robot is large in transverse size and only the leg length can be adjusted or fixed in a stepped mode are overcome. The transversely arranged motor is changed into a vertically arrangedmotor, so that the overall size of the exoskeleton is greatly reduced. Connecting rods with sliding rails are adopted at the thighs of the exoskeleton, so that the length of the exoskeleton can be adjusted in a stepless mode, the whole exoskeleton can better meet the requirements of different patients, and the rehabilitation training effect is improved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to a servo motor lower limb exoskeleton rehabilitation robot. Background technique [0002] The driving motors and reducers of traditional lower extremity exoskeleton rehabilitation robots are generally imported from abroad, which are expensive and difficult to maintain. The motors of traditional lower extremity exoskeleton rehabilitation robots are generally installed on the outside of the hip joint and knee joint parallel to the ground, resulting in a large lateral volume of the entire exoskeleton and inconvenient movement of the exoskeleton. Moreover, most exoskeletons can only be adjusted in grades or have fixed leg lengths, which cannot meet the needs of different patients with different leg lengths. Therefore, traditional exoskeleton rehabilitation robots are often installed on fixed lower limb rehabilitation robots. And above-mentioned shortcoming causes rehabi...
