Intelligent artificial limb with active bending locking function

Abstract

The invention discloses an intelligent artificial limb with an active bending locking function. The intelligent 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, and the bottom of the rack is connected with the ankle-foot part; a hydraulic cylinder is hinged in the rack, and a hydraulic rod of the hydraulic cylinder is connected with the joint head; a driving servo motor connected with the hinged end of the hydraulic rod is arranged on the joint head; the hydraulic cylinder active servo motor is connected with the controller; and connecting rods are movably connected to the two sides of the rack respectively, the upper portion of the hydraulic cylinder is connected with the two connecting rods respectively, lock discs are arranged on the two sides of the lower portion of the joint head, and lock heads capable of making contact with the lock discs are arranged on the inner sides of the connecting rods. Intelligent adjustment of bending damping of the artificial limb is achieved, joint locking can be achieved when the artificial limb stands, the stability of the artificial limb joint is greatly improved, the artificial limb has functions of going upstairs and going downstairs, and the switching between a going-upstairs mode and a going-downstairs mode is natural and smooth.

Description

technical field [0001] The invention relates to the technical field of intelligent artificial limbs, in particular to an intelligent artificial limb with an active bending locking 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 ca...

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.
