Problems solved by technology

[0003] Electromagnetic induction power generation is a classic power generation method, but traditional electromagnetic power generation devices mainly use external energy to drive the rotation or plane movement of the coil to cut the magnetic induction line to complete the electromagnetic induction power generation process. This method requires the device to have special The structure is designed to ensure that the external energy can be converted into a specific rotation or plane movement. The structure is more complicated and the volume is larger.

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] A magnet levitation vibration-driven electromagnetic energy harvester, such as figure 1 As shown, it includes a magnetic column placement ring 8 located in the middle, and several magnetic column placement grooves 9 are evenly distributed on the inner wall of the magnetic column placement ring 8 in the axial direction. The main magnet cavity 7 is arranged in the magnetic column placement ring 8. The circular permanent magnet 5 is placed in the main magnet cavity 7; the cylindrical permanent magnet 6 is placed in the corresponding magnetic column placement groove 9, and the circular permanent magnet 5 is placed in the center of the array formed by the cylindrical permanent magnet 6. , so that the circular permanent magnet 5 is in a suspended state; an upper plane spiral coil 2 and a lower plane spiral coil 4 are arranged symmetrically ab...

Abstract

The invention provides a magnet suspension-type vibration driving electromagnetic energy harvester, which comprises upper and lower planar spiral-shaped coil protection outer shells, a main magnet cavity, a magnetic cylinder accommodating ring, a circular permanent magnet, cylindrical permanent magnets, and upper and lower planar spiral-shaped coils, wherein the circular permanent magnet is in a central suspension state and has an automatic rapid homing function, autonomously vibrates through inducting external vibration, so as to cause changes of magnetic flux of the upper and lower planar spiral-shaped coils, and further can convert external vibration energy into electric energy repeatedly. The design has high sensitivity for the external vibration and low loss in energy conversion process, can acquire slight vibration energy as well as intensive vibration energy, is wide in dynamic range and high in structural stability, and has broad application prospect in implementing a self-power supply operating mode of portable electronic products.

Description

technical field [0001] The invention belongs to the technical field of energy materials and devices, and in particular relates to a magnet-suspended vibration-driven electromagnetic energy harvester. Background technique [0002] With the rapid growth of social production demand and the rapid development of sensor and microsystem technology, a large number of micro-nano sensor devices and systems are being widely used. Especially wearable micro-nano sensing system. At present, this type of system mainly relies on batteries for power supply, and the battery life is limited, and the life is relatively short, and it needs to be replaced frequently. Even if it is a rechargeable battery, its life is relatively long, but frequent charging will also bring inconvenience to users. . Such a battery power supply method will not only generate more usage costs, but also cause environmental pollution due to the generation of a large number of waste batteries. Wearable equipment is clos...
