Novel mechanical arm used for upper limb rehabilitation robot

Abstract

The invention relates to the technical field of mechanical arm elements, and discloses a novel mechanical arm used for an upper limb rehabilitation robot. The novel mechanical arm used for the upper limb rehabilitation robot comprises a first motor, a second motor, a third motor, a first position sensor, a second position sensor, a third position sensor, a first acceleration sensor, a second acceleration sensor, a third acceleration sensor and a controller. According to the novel mechanical arm used for the upper limb rehabilitation robot, multiple sensors are combined in joint components, force measurement is enabled to be easier, the softness, the safety and the flexibility of the robot are ensured, the force of upper limb rehabilitation training sensitivity operation is improved, a design structure of the mechanical arm is constituted by making multiple rotary joint components in series connection, each joint component is provided with a driving mechanism of a motor reducer, the driving mechanisms can drive the arm to actively move, and therefore rehabilitation training is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical arm components, and in particular relates to a novel mechanical arm for an upper limb rehabilitation robot. Background technique [0002] Facts have proved that the emerging rehabilitation robot technology has great potential to help patients recover through upper and lower limb rehabilitation training. They can replace and reduce the heavy physical and high-intensity workload of physical therapists. The suitability of robots for repetitive tasks allows for better implementation of robotic rehabilitation programs designed to help neurologically damaged patients regain their motor function. Among the functional disabilities caused by nervous system damage, the functional impairment of the upper limb system affects the patient's function the most. The disability caused by the functional impairment of the upper limb system has a significant impact on the independence and quality of life of the pat...
