Permanent magnet synchronous motor-built-in lead screw driven double-feet walking device

Abstract

The invention discloses a permanent magnet synchronous motor-built-in lead screw driven double-feet walking device, which is used for assisting the walking of human being and reducing the physical exhaustion of the human being during long-time walking, and can also be used for lower limb rehabilitation training. The permanent magnet synchronous motor-built-in lead screw driven double-feet walkingdevice comprises a thigh motor-built-in lead screw driving mechanism, a thigh magnetoelectric type position feedback device, a shank motor-built-in lead screw driving mechanism, a shank magnetoelectric type position feedback device, a foot motor-built-in lead screw driving mechanism, a foot magnetoelectric type position feedback device, a hip structure, a power supply and a driving controller. A magnetoelectric type angle displacement sensor is used for detecting the swinging included angles among the thighs, shanks and feet, a ball screw is built in a permanent magnet synchronous motor rotor,a permanent magnet synchronous motor is rotated, the screw is moved front and back so as to further drive the legs and feet to dial and swing, the length of legs can be adjusted by adjusting set screws of thighs and shanks so as to get adapted to different crowds, the permanent magnet synchronous motor-built-in lead screw driven double-feet walking device can be used for lower limb rehabilitationtraining and can reduce the physical exhaustion of the human during walking.

Description

technical field [0001] The invention discloses the field of rehabilitation treatment equipment for lower limbs and the field of energy-saving transportation equipment, and in particular relates to a biped walking device driven by a lead screw with a built-in motor. Background technique [0002] With the development of our country's society and the improvement of people's living standards, people pay more and more attention to auxiliary treatment. In the medical field, patients with lower limb diseases have the problem of being unable to walk actively, resulting in long recovery time. With the development of robot technology It is an inevitable trend to use biped walking devices to assist patients with lower limb diseases to walk and shorten the recovery time. In the field of energy-saving transportation, assisted walking robots can reduce people's fatigue caused by long-distance walking and increase people's chances of traveling in a more environmentally friendly way. The f...

AI Technical Summary

Problems solved by technology

The mechanical structures of these two kinds of walking devices are heavy, the work efficiency is low, and the failure rate is high, so it is difficult for patients to wear them.

In addition, the existing electric walking aids do not consider the needs of people of different heights, cannot adjust the length of the legs, and have low adaptability
