Planar upper limb rehabilitation training robot

Abstract

The invention discloses a planar upper limb rehabilitation training robot. The planar upper limb rehabilitation training robot comprises a working platform, a motor driving assembly, a transmission assembly and a handle assembly. The motor driving assembly, the transmission assembly and the handle assembly are separately mounted on the working platform. Transmitted by a steel wire rope, an action of reducing the speed and increasing the force is realized. Compared with a common gear reduction box, the robot has an excellent reverse driving ability, and a control system better monitors the movement intention of a patient, so that smoother human-machine interactive experience is realized; a universal ball is designed in the handle assembly to convert the gravities of the hand of the patient and the connecting rod into a planar frictional force to prevent a mechanical arm from being suspended so as to reduce the bending moment subjected to the mechanical arm and a rotary shaft, so that the stability and the control precision of the system can be effectively increased; the positions of the handle and a soft cushion can be exchanged, so that the effective active space of the user is changed, and the training range of the shoulders of the patient is expanded.

Description

technical field [0001] The invention relates to the fields of robot technology, human biomechanics, rehabilitation medicine and rehabilitation engineering, in particular to a planar upper limb rehabilitation training robot. Background technique [0002] With the continuous development of rehabilitation engineering and intelligent technology, more and more robots are used in the field of rehabilitation. Upper limb dysfunction caused by cerebrovascular disease, sports injury, postoperative complications, etc. often requires therapists to conduct one-on-one rehabilitation to help patients recover upper limb mobility and muscle strength. However, the shortage of therapists is currently a major status quo. However, the existing upper limb training apparatus has simple functions and a single mode, and cannot record the patient's performance in training. Therefore, it is necessary to design an upper limb rehabilitation robot with various modes, which can improve the patient's t...
