A portable miniature power generating device

Abstract

The invention relates to a portable micro power generation device which comprises a spiral spring, bearings, a magnet support, framework inner side magnet clamping grooves, a lead groove, a first arc-shaped permanent magnet with an outer slope at the top end, a second arc-shaped permanent magnet with an outer slope at the top end, a silicon steel sheet stacking iron core, a fixed shaft, a wire groove, screws, a first coil, a second coil and a third coil. The silicon steel sheet stacking iron core, the fixed shaft provided with the lead groove, the first coil, the second coil and the third coil form a stator, the middle portions of the two ends of the magnet support are arranged on the fixed shaft through the bearings, the inner end of the spiral spring is fixed to the fixed shaft, the outer end of the spiral spring is fixed to the edge of the magnet support, the first arc-shaped permanent magnet with the outer slope at the top end and the second arc-shaped permanent magnet with the outer slope at the top end are correspondingly fixed to the two sides of the magnet support through the framework inner side magnet clamping grooves in the two ends of the magnet support, the magnet support is screwed through the screws to form a rotor, the two arc-shaped permanent magnets with the same geometrical shape are made of different isotropic magnetic materials, and the magnet support is made of aluminum alloy.

Description

technical field [0001] The invention relates to a portable micro power generating device, which belongs to the field of micro electromechanical equipment. Background technique [0002] At present, there are still many small, hand-held or mobile electronic devices with high power consumption. It is often necessary to replace the battery or charge the storage battery. Advanced batteries not only have an impact on the environment, but also cause a waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable miniature power generation device to pick up the vibration energy provided by the outside during the use of small, hand-held or mobile electronic devices, convert mechanical energy into electrical energy, and provide small, hand-held or mobile electronic devices The equipment is powered to achieve independent power supply and long-term uninterrupted work. [0004] The technical solution adopte...
