Intelligent damping artificial limb with active bending function

Abstract

The invention discloses an intelligent damping artificial limb with an active bending function. The artificial limb comprises a thigh part, a shank part and an ankle-foot part, the shank part comprises a rack and a joint head hinged to the top of the rack, the bottom of the rack is connected with the ankle-foot part, a hydraulic cylinder is hinged to the interior of the rack, a hydraulic rod of the hydraulic cylinder is hinged to the joint head, an overflow valve servo motor is arranged on the hydraulic cylinder, and an active servo motor connected with the hinged end of the hydraulic rod is arranged on the joint head; and the hydraulic cylinder, the overflow servo motor and the active servo motor are all connected with the controller. Intelligent adjustment of artificial limb bending damping is achieved, the joint active bending function is achieved, intelligence and labor saving are achieved, walking of a patient is greatly facilitated, the walking process is completely smooth through a flexible feedback driving mechanism, real-time artificial limb mode switching is achieved through multi-point sensor signal collection, damping adjustment is smooth and errorless through high-speed motor driving, and the user experience of the patient is perfected.

Description

technical field [0001] The invention relates to the technical field of intelligent artificial limbs, in particular to an intelligent damping artificial limb with active bending function. Background technique [0002] Due to various reasons such as wars, diseases, industrial injuries, traffic accidents and natural disasters, millions of people have lost their healthy lower limbs, and some people have lost their ability to work, which hinders their normal social interactions and bears a huge physical and mental burden. On the other hand, physical disabilities often affect people's daily life, reduce their quality of life, and also bring a heavy burden to their nursing families and society. Since the current level of medical treatment cannot regenerate limbs, installing prosthetic limbs for these amputees has become an important means of compensating for missing limbs. [0003] Ordinary prosthetics do not have the ability to actively bend, and are laborious to use, which can e...

AI Technical Summary

Problems solved by technology

[0003] Ordinary prosthetics do not have the ability to actively bend, and are difficult to use, which can easily cause patient fatigue. Ordinary prosthetics are more complicated in mode adjustment, and often require special movements or manual adjustments, which are not natural and coherent.
