Magneto-rheological damper sitting-lying type lower limb rehabilitation robot

Abstract

The invention discloses a magneto-rheological damper sitting-lying type lower limb rehabilitation robot, and relates to the technical field of medical instruments. The magneto-rheological damper sitting-lying type lower limb rehabilitation robot is characterized in that a hip joint bracket is arranged vertically; the bottom end of the hip joint bracket is fixedly connected with a hip joint extension bracket, and is connected to the output end of a hip joint extension driving mechanism through the hip joint extension bracket; the front end and the tail end of an upper limb rod are rotationallyconnected to the top end of the hip joint bracket and the top end of a lower limb rod; the outer sides of the hip joint bracket and the upper limb rod are provided with a magneto-rheological driving mechanism respectively; driven belt wheels of the two magneto-rheological driving mechanisms are connected to the front end of the upper limb rod and the top end of the lower limb rod. A disk type magneto-rheological damper is arranged in the magneto-rheological driving mechanism, so that control over the output torque of a motor is realized, and the problem of overlarge output torque of the driving motor is solved. Meanwhile, a resistance effect can be provided during active exercise of a patient, so that the effect of rehabilitation effect is enhanced. The magneto-rheological damper sitting-lying type lower limb rehabilitation robot has the advantages of simple overall structure, convenience in use and high practicability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a robot for rehabilitation treatment of lower limbs. Background technique [0002] Rehabilitation therapy, also known as rehabilitation physical therapy, is a special therapy that can prevent, improve and recover the dysfunction and low function of the patient's body. Traditional rehabilitation procedures rely on the therapist's experience and hands-on skills. In recent years, with the rapid increase in the number of patients, reforms to save medical resources and improve the efficiency of rehabilitation treatment are imminent. [0003] Rehabilitation robot is a new type of robot that has emerged in recent years and belongs to the category of medical robots. It mainly drives the limbs to do repetitive movements through machines, stimulates and promotes the reconstruction of the nervous system that controls the movement of the limbs, and is a new type of clinical inte...

Problems solved by technology

[0009] The control method of this technical solution is complicated, the motor output torque control accuracy is not high, and when the output torque is too large, there is no installation safeguard for the human body; when people perform resistance training, the resistance cannot be adjusted
