A kind of power supply device for electronic equipment and its application

Abstract

The invention provides electronic equipment and a power supply device applied by the electronic equipment. The power supply device comprises three gears and a booster rod, wherein the three gears are a first gear, a second gear and a third gear respectively; the first gear is used for rotating according to the rotating force applied to a first shaft of the first gear; the second gear is engaged with the first gear; the second gear and the third gear are arranged on the same second shaft, so that the third gear and the second gear are kept in synchronous rotation; the booster rod is arranged between the second gear and the third gear, and comprises a fixed part and two end parts; the fixed part is fixed on the second shaft; the two end parts contact the third gear; and the booster rod is used for assisting the second shaft in pushing the third gear to rotate through the two end parts contacting the third gear when the second gear rotates, so as to assist in promoting a ring magnet to rotate. According to the electronic equipment, input kinetic energy can be converted into electric energy; the electric energy is stored; and the power supply device is started to supply electricity to the electronic equipment when a battery of the electronic equipment runs low, therefore, the power supply device is convenient to use and high in practicability.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an electronic device and a power supply device for its application. Background technique [0002] At present, the world is in a period of rapid development of power electronics technology. Most people have all kinds of electronic products with them, and the continuous power supply of electronic products is a great demand for people to use electronic products. When there is no power supply equipment with them, if you can manually It will bring a lot of convenience to the user to charge the electronic device just by operating it. In the prior art, a variety of devices for manually powering simple electronic devices such as flashlights are provided, but their functions and structures are relatively simple and cannot meet the demand for powering multifunctional intelligent electronic devices. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior ar...
