A left and right hand exchange mechanism for a rope-driven upper limb rehabilitation training device

Abstract

The invention provides a left and right hand exchange mechanism for a rope-driven upper limb rehabilitation training device, comprising: a wrist reversing part, including a supporting plate for supporting the wrist, a narrow connecting plate fixed at the bottom of the supporting plate, and one end fixed on the narrow connecting plate. The Z-shaped connecting plate adjacent to the supporting plate and the Hall joystick arranged on one side of the Z-shaped connecting plate; the forearm compensation part, including the short connecting plate connected to the other end of the Z-shaped connecting plate, through screws The slider connected with the short connecting plate and the linear guide rail guide groove embedded with the slider and used for the movement of the slider; the flexion and extension part of the elbow, including the forearm link connected with the linear guide rail guide groove, is connected with the forearm link through a pin The elbow cable pulley, the elbow limit block fixed on the bottom of the forearm link through pins, the two steering positioning pins set on the elbow limit block, the elbow cable pulley and the forearm link are placed in the opening. The C-shaped joint joint at the rod end and the through hole passing through the top plate and the bottom plate of the C-shaped joint joint, the elbow cable pulley and the flexion and extension rotating shaft at the end of the forearm connecting rod.

Description

technical field [0001] The invention relates to an upper limb rehabilitation mechanical mechanism driven by a rope, in particular to a left and right hand exchange mechanism used for a rope-driven upper limb rehabilitation training device. Background technique [0002] With the continuous development of the times, the health care work for the elderly and the disabled has gradually been replaced by more intelligent and convenient rehabilitation robotic arms. In order to adapt to the concept of family rehabilitation nursing, the rehabilitation robotic arm has begun to develop in a more intelligent and compact direction. , The appearance of the cable type upper limb rehabilitation manipulator broke the design idea of ​​the traditional rehabilitation manipulator. Each joint of the traditional rehabilitation robotic arm needs to be equipped with a motor, which not only increases the burden on the operation of the rehabilitation robotic arm, but also seriously affects the nursing ...

AI Technical Summary

Problems solved by technology

[0003] There are not many studies on the cable-type rehabilitation manipulator in the current frontier of science and technology. The reason may be that the design difficulty of the driving method of the cable will increase, and the utilization rate of the upper limb rehabilitation training manipulator is not high. The reversing structure of the robotic arm for left / right arm separate training is relatively complicated. Based on the current problems, we designed and developed a left / right hand interchange mechanism for the rope-driven upper limb rehabilitation trainer
