Power generation device driven by human knee and ankle joints

Abstract

The invention relates to a power generation device driven by human knee joints and ankle joints, and belongs to the technical field of human body power generation devices. Including power generation mechanism, knee rope, ankle rope, thigh support, calf support, calf support link, ankle link; power generation mechanism includes generator, worm gear mechanism, first input mechanism, second input mechanism and transition transmission mechanism; transition The transmission mechanism includes a pair of gears and a transition gear; the transition transmission mechanism is respectively connected to the first input mechanism and the second input mechanism, and the worm shaft of the worm gear mechanism is connected to the input shaft of the generator; the power generation mechanism is connected to the One end of the knee rope is connected to the thigh support, and the other end is wound on the first pulley of the first input mechanism; one end of the ankle rope is wound on the second pulley, and the other end is connected to the ankle link. The invention collects the negative work generated by the knee and ankle joints when the human body walks, reduces the metabolic consumption, and realizes that people can obtain electric energy at any time while walking.

Description

technical field [0001] The invention belongs to the technical field of human body power generation devices, and in particular relates to a power generation device driven by human knee and ankle joints and a control method thereof. [0002] technical background [0003] With the continuous progress of society, various wearable electronic devices, exoskeletons and prosthetics are developing rapidly, and the continuous power supply of these devices is a problem that plagues people. When users need to work continuously for a long time or work outdoors, they cannot be charged in time. For soldiers performing outdoor tasks, continuous power supply is an important guarantee for their successful completion of tasks; and in order not to affect the flexibility of users' outdoor activities, The volume and weight of the power source carried by the user should be reduced as much as possible, but the existing battery has low energy density, long charging time, and short life, which cannot ...

AI Technical Summary

Problems solved by technology

A knee joint power generation device, which adopts a ball screw structure, converts the rotational motion of the knee joint into the linear motion of the screw nut through the pull rope, and then converts it into the high-speed rotational motion of the ball screw, and finally realizes the function of the generator to generate electricity. On the one hand, the large amount of positive power collected by the device at the knee joints of the human body will increase the consumption of metabolism; on the other hand, the generator needs continuous forward and reverse rotation during bidirectional collection, and the inertia of the generator rotor is likely to have an impact on the human body.
