A portable miniature power generating device

technical field

The invention relates to a portable micro power generating device, which belongs to the field of micro electromechanical equipment.

Background technique

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

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.

The technical solution adopted by the present invention to solve its technical problems is: the present invention consists of a worm spring, a bearing, a magnet bracket, a magnet slot inside the frame, a lead groove, a first top end with an outer slope arc permanent magnet, a second top end with a Outer slope curved permanent magnet, iron core made of silicon steel sheets, fixed shaft, wire groove, screw, first coil, second coil, third coil, silicon steel laminated iron core is fixed at both ends with lead grooves On the fixed axis, the first coil, the second coil, and the third coil are symmetrically and tightly wound in the corresponding slots on the laminated iron core of silicon steel sheets to form a stator. In the radial-like magnetic field formed by the permanent magnet and the arc-shaped permanent magnet with an outer slope on the second top, it is characterized in that: the middle of the two ends of the magnet bracket is installed on the fixed shaft through bearings, and the inner end of the worm spring is fixed on the fixed shaft and the outer The ends are fixed on the edge of the magnet bracket, and the magnet slots inside the frame at both ends of the magnet bracket fix the first top end with an outer slope arc-shaped permanent magnet and the second top end with an outer slope arc-shaped permanent magnet on both sides of the magnet bracket correspondingly, the magnet bracket Twist together with screws to form the rotor. The first top with the same geometrical shape has an arc-shaped permanent magnet with an outer slope, and the second top with an arc-shaped permanent magnet with an outer slope. It is made of different isotropic magnetic materials, and the magnet bracket is made of aluminum alloy. make.

Due to the adoption of the above-mentioned technical scheme, the advantages and positive effects of the present invention are: two permanent magnets with different masses are used to make a rotor whose center of mass deviates from the rotating shaft, and pick up the vibration provided by the outside during the use of small, hand-held or mobile electronic devices. Energy, under the joint action of the worm wire spring, maintains the relative motion between the rotor and the stator, converts mechanical energy into electrical energy, realizes independent power supply, long-term uninterrupted work, and the device structure is simple, reliable, economical and practical.
