Power generating device

摘要

The invention discloses a power generating device comprising a first shell, a magnetic unit, a second shell and an inductance coil. The first shell comprises at least a first engaging part. The magnetic unit is disposed on the first shell. The second shell comprises at least a second engaging part which is detachably engaged to the first engaging part making the first shell and the second shell form a space, wherein the magnetic unit is disposed inside the space. The inductance coil is disposed on the second shell inside the space, and the magnetic unit is surrounded by the inductance coil. When an external force is applied to the first shell and the second shell, the first engaging part moves relatively to second engaging part, and the inductance coil generates an induced current by sensing changes of a magnetic flux.

1. A power generating device, comprising:
a first shell, comprising a plurality of first engaging parts integrally formed on a radial surface of the first shell and extending outward horizontally therefrom, the plurality of first engaging parts having an opening formed therebetween; a magnetic unit fixed on the first shell; a second shell, comprising an indentation and at least a second engaging part integrally formed therewith, the second engaging part formed on a top surface of the second shell corresponding to the first shell, the second engaging part extending outward vertically from the top surface, the second engaging part detachably engage with the first engaging part so as to form a space between the first shell and the second shell, wherein the magnetic unit is disposed inside the space; an inductance coil, disposed on the second shell inside the space; and an elastic unit embedded in the indentation of the second shell, rather than configured between the first engaging part and the second engaging part; wherein, when an external force is applied, the first engaging part moves vertically relative to the second engaging part and at least part of the second engaging part enters the opening vertically during the movement, the inductance coil generates an induced current by sensing changes of a magnetic flux, at least part of the magnetic unit being surrounded by the inductance coil before and after the external force is applied.
