Problems solved by technology

[0003] At present, there are two main solutions to solve the dynamic torque feedback of rehabilitation robot joints. One is to install dynamic torque sensors at the joints of rehabilitation robots, which have high precision and good real-time performance, but dynamic torque sensors are expensive, large in size and heavy in weight. , it is difficult to achieve a compact and lightweight low-cost design; the other is to install a six-axis force (torque) sensor at the corresponding position of the rehabilitation robot, and then decompose the force to each joint. Similarly, the six-axis force (torque) sensor is also facing and Similar issues with dynamic torque sensors

Abstract

The invention relates to the field of medical rehabilitation machinery, in particular to a cylinder-driven robot joint device. A first connecting rotating shaft is installed in a bore of a base crossbeam, a first rotating shaft gear is fixed to the first connecting rotating shaft, and the first connecting rotating shaft is connected to a shoulder joint rotating arm through a self-lubricating bearing. The first rotating shaft gear meshes with an incremental encoder gear, and the incremental encoder gear is connected with an incremental encoder. The incremental encoder gear meshes with a Hall sensor gear, and the Hall sensor gear is connected with a Hall sensor. The incremental encoder and the Hall sensor are mounted on the shoulder joint arm. The cylinder-driven robot joint device has thecharacteristics of good safety performance, high controllability and the like.

Description

technical field [0001] The invention relates to the field of medical rehabilitation machinery, in particular to a cylinder-driven rehabilitation robot joint device. Background technique [0002] The upper limb rehabilitation training robot is produced by combining the field of robot technology and the field of rehabilitation medicine. It is a new technology that supplements or replaces professional doctors to complete the rehabilitation training of human upper limbs. Its appearance opens up new opportunities for the rehabilitation of patients with upper limb hemiplegia. The road makes up for the lack of clinical treatment of hemiplegic patients. The treatment method of the rehabilitation training robot is to connect the affected limb with the robot, and the patient's limbs are driven by the robot to complete various actions and stimulate the neural control system of the upper limb joints and muscles of the human body, so as to achieve the purpose of restoring the motor funct...
