Abstract

The invention discloses a string twisting driving upper limb rehabilitation robot which comprises a lower supporting device, a string twisting driving device, a shoulder joint support, an upper arm assembly, a front arm assembly and a traction device. The string twisting driving device comprises a plurality of driving motors and a plurality of driving sliding blocks which are arranged on the lower supporting device; each driving motor is connected with the driving sliding block through a twisted string and converts rotary motion of an output shaft of the driving motor into linear motion of the driving sliding block through the twisted string, and the traction device comprises a plurality of driving ropes connected with the driving sliding block. The driving rope is connected with the upper arm assembly and the front arm assembly and drives the upper arm assembly and the front arm assembly to act through the driving rope. According to the driving device, the driving motor is connected with the driving sliding block through the twisted string, so that the rotary motion of the output shaft of the driving motor is converted into the linear motion of the driving sliding block, then the shoulder joint and the elbow joint are driven to rotate through the driving rope connected with the driving sliding block, the complexity of the driving device is effectively reduced, and the control mode is simplified.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation robots, and in particular, the invention relates to a twisted string-driven upper limb rehabilitation robot. Background technique [0002] With the increasing problem of aging population, the number of patients with limb dysfunction caused by stroke is increasing year by year around the world. Therefore, it is particularly important for stroke patients to carry out rehabilitation training as soon as possible. Effective rehabilitation training can assist patients to maximize motor dysfunction and reduce sequelae. With the rapid development and maturity of today's robotics technology, the combination of robotics and rehabilitation engineering has become possible. People gradually introduced robotic technology into rehabilitation engineering, and created various devices and equipment for rehabilitation purposes, among which rehabilitation robots are a new field. [0003] At present, most of ...
