Description

Technical Field

[0001] The present application relates to the field of walking rehabilitation robots, and in particular to a multifunctional walking rehabilitation robot. Background Art

[0002] A walking rehabilitation robot is a robotic device specifically designed to assist patients with lower limb movement disorders with rehabilitation training. It uses external force to drive the lower limbs for scientific, efficient, and accurate walking rehabilitation training, stimulating nervous system remodeling and improving autonomous walking ability, thereby accelerating the rehabilitation process. Based on the principle of "neuroplasticity," the walking rehabilitation robot uses external force to drive the lower limbs for walking training, simulating the joint angles maintained during walking. This fully trains patients' hip and knee extension and flexion functions, as well as the synchronization of hip and knee joint movements. This reestablishes patients' hip extension and knee flexion abilities, as well as their ability to separate the hip and knee. When in use, a conventional walking rehabilitation robot has a backrest fixed to the patient's back. The lower end of the backrest is rotatably mounted with an upper leg control frame, which controls the patient's thigh swing. The lower end of the upper leg control frame is rotatably connected to a lower leg control frame, which assists in the swing of the patient's calf, facilitating walking rehabilitation.

[0003] Regarding the above-mentioned related technologies, the inventor believes that after the patient walks for a period of time, the conventional walking rehabilitation robot will easily cause fatigue due to the obstruction of lower limb movement in the patient, and the walking rehabilitation robot is difficult to provide a way for the patient to rest, resulting in the patient needing to disassemble the rehabilitation robot to facilitate the patient's rest when tired, resulting in a long time being spent in the rest process.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
