A joint generator

Abstract

The invention discloses a joint power-generation device. The device comprises a support seat 1, two sliding chutes 6 symmetrically fixed on wall plates on both sides of the support seat 1, an oscillating shaft 3 penetrating through a circular hole 12 in the support seat 1, an oscillating rod 4 connected with the outer end of the oscillating shaft 3, an oscillating gear 2 fixed on the inner end of the oscillating shaft 3, a sliding rack 5 driven by the oscillating gear 2, an input gear 7 driven by the sliding rack 5, an unidirectional device 9 driven by the input gear 7 and a power generator 11 of which a rotor 10 is driven by the output end of the unidirectional device 9. The power-generation device can be worn on a knee joint or an elbow joint of a user and has the capability of converting mechanical energy generated when the user shakes the shanks or forearms in a walking process into electric energy and storing the electric energy in an electricity storage device so as to supply power to various electric appliances. The joint power-generation device is convenient to carry and long in service life and can be used for well solving the problems that a portable electronic product and a wearable electronic product suffer from power shortage.

Description

technical field [0001] The invention relates to the fields of mechanics and electricity, in particular to a portable joint power generating device. Background technique [0002] At present, the use of portable electronic products is becoming more and more common. When people go out or carry out outdoor activities, the use of electronic equipment becomes indispensable, but these electronic products often have the defect of insufficient battery power supply, which brings The power supply problem of electronic equipment has caused great troubles to people. Human body activities carry a large amount of mechanical energy. If these mechanical energy are converted into electrical energy by appropriate methods and provided to these portable electronic devices, the electronic devices can be freed from the limitations and shackles of insufficient power. In recent years, some portable power generation devices that convert mechanical energy into electrical energy have emerged one after...
