An arm length adjustment device for an upper limb exoskeleton rehabilitation robot

Abstract

The invention belongs to the related field of medical rehabilitation training equipment, and particularly discloses an arm length adjusting device for an upper limb exoskeleton rehabilitation robot. The arm length adjusting device comprises an upper left bracket, an upper right bracket, a lower bracket and a worm and gear assembly. The worm and gear assembly is arranged between the upper bracket and the lower bracket, and comprises a worm wheel, a worm and a screw rod. The screw rod is fixed between the upper left bracket and the upper right bracket in the axial direction. The screw rod is mounted between the upper left bracket and the lower bracket. The worm wheel is coaxially mounted above the screw rod. A rocker component is arranged at the right end of the upper right bracket and is connected with the right end of the worm. A polished rod is arranged between the upper right bracket and the lower bracket. The screw rod and the polished rod penetrate through a horizontal connecting plate and a lower movable rack between the upper bracket and the lower bracket. An up-down moving component is fixedly mounted on the same sides of the horizontal connecting plate and the lower movable rack. The arm length adjusting device can realize the arm length adjusting function of the shoulder-elbow part of the upper limb exoskeleton rehabilitation robot, and is suitable for upper limb sizes of different patients, and the adjusting step is simple and easy.

Description

technical field [0001] The invention belongs to the related field of medical rehabilitation training equipment, and more specifically relates to an arm length adjustment device of an upper extremity exoskeleton rehabilitation robot, which can be adjusted according to the arm length, and the adjustment steps are simple and easy. Background technique [0002] The upper limb exoskeleton rehabilitation robot is used to assist hemiplegic patients to carry out corresponding upper limb activities, so as to promote upper limb movement and help rehabilitation training. The heavy work of rehabilitation physicians can be liberated through robots, thereby significantly improving the efficiency and effectiveness of rehabilitation training. [0003] The length of the upper limbs of each hemiplegic patient undergoing rehabilitation training is different. If the rehabilitation robot has a reliable and convenient upper limb length adjustment device, the comfort and rehabilitation effect of t...

AI Technical Summary

Problems solved by technology

Therefore, the upper limb rehabilitation robot with non-adjustable upper limb length and inconvenient adjustment obviously does not meet the requirements of high efficiency and good training effect

[0004] Existing upper limb exoskeleton rehabilitation robots either do not have an arm length adjustment device and cannot adapt to the patient's upper limb length in a differentiated manner; or the arm length adjustment steps are cumbersome, time-consuming and laborious, and it is difficult to adjust the arm length to the most comfortable position
