Lower limb rehabilitation training robot and suspension weight reduction mechanism thereof

Abstract

The invention provides a lower limb rehabilitation training robot and a suspension weight reduction mechanism thereof. The suspension weight reduction mechanism comprises a suspension frame, a suspension rope group, a rope winding device and a motor. The suspension frame comprises a first upright post, a second upright post, a first rope penetrating bent post and a second rope penetrating bent post, wherein the first upright post and the second upright post are arranged side by side; the first rope penetrating bent post is fixedly connected above the first upright post; and the second rope penetrating bent post is fixedly connected above the second upright post. The suspension rope group includes a first suspension rope and a second suspension rope. The rope winding device comprises a ropewinding shaft for winding and unwinding the first suspension rope and the second suspension rope, and the rope winding shaft is driven by a motor. The rope winding shaft comprises a first output shaft and a second output shaft which are coaxially arranged; one end of the first output shaft is connected with the motor, and the other end of the first output shaft is connected with a first winding wheel; the first suspension rope is arranged on the first winding wheel in a winding manner and penetrates out of the first rope penetrating bent post; one end of the second output shaft is connected with the motor, the other end of the second output shaft is connected with a second winding wheel, and the second suspension rope is arranged on the second winding wheel in the winding manner and penetrates out of the second rope penetrating bent post. The lower limb rehabilitation training robot and the suspension weight reduction mechanism thereof not only can ensure synchronous hoisting so as toeffectively ensure a balance of hoisting, but also is small in size and simple in operation.

Description

technical field [0001] The invention relates to medical rehabilitation equipment, in particular to a lower limb rehabilitation training robot and a suspension weight reduction mechanism thereof. Background technique [0002] Cerebrovascular diseases such as stroke, and central nervous system injuries such as brain or spinal injuries seriously threaten human health and life safety, and have a high disability rate. Most patients have varying degrees of loss of living ability and working ability. According to statistics, more than half of patients with limb dysfunction in my country can be improved through post-rehabilitation training and regain walking ability. At present, in traditional rehabilitation training, professional physical therapists repeatedly pull the patient's affected limb "hand in hand". This method not only increases the labor intensity of doctors, but also requires high treatment costs. [0003] With the development of science and technology, medical robots ...

AI Technical Summary

Problems solved by technology

The existing active or passive single-rope suspension weight-reducing devices have the following disadvantages: since the single-rope weight-reducing device only bears a little force, it will generate front and rear and lateral pulling forces on the patient; The tension of the spring is used for dynamic weight reduction, the volume is larger and the operation is more complicated, and generally one motor can only preset the tension of one strand of rope
