Abstract

The invention discloses a motor-driven active ankle joint artificial limb and a method thereof. The active ankle joint artificial limb comprises an ankle shell, a driving motor, a control circuit, a rocker transmission device, a foot elastic structure, a wireless sensor data collection part and a connecting part. When a power supply is switched on, sensors are started, and a control circuit PCB iselectrified, the sensors start to work, through operations, the driving motor is started, the rotational speed of the driving motor is regulated, through mechanical transmission, a rocker performs reciprocating swinging, and then the whole gait cycle is completed; and when the power supply is in power failure, the rocker is free from driving force from the driving motor, but swings because the foot elastic structure is stressed to bend, and at the time, other structures all achieve the supporting effects. The device is adapted to various terrains and various gait environment, is good in interaction with a human body and is suitable for groups of which shin lower ends are amputated.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to an active ankle joint prosthesis driven by a motor and a method thereof, in particular, to an active ankle prosthesis that adjusts the rotation angle of the foot prosthesis through electric drive to satisfy the degree of freedom of the ankle. Prosthetics and methods of use thereof. Background technique [0002] With the development of the times, the number of disabled persons with limb loss due to car accidents, wars and other reasons is increasing, and more than 70% of them are lower limb loss, of which the loss below the knee accounts for the majority. [0003] Japan, Europe, the United States and other countries have been ahead of the domestic market for more than 20 years. Foreign products are expensive and difficult to maintain. Domestic products are integrally formed, inconvenient to disassemble and cannot meet the needs of the audience, causing domestic audiences to suf...
