Embodiment Construction

[0014] The invention provides a giant magnetostrictive vibration energy harvester amplified by a flexible hinge, which can convert the vibration energy of the surrounding environment into electric energy to provide energy for the operation of a microelectronic system.

[0015] Such as figure 1 with figure 2 As shown, the giant magnetostrictive vibration energy harvester amplified by a flexible hinge mainly includes a sleeve 1, a permanent magnet 2, a giant magnetostrictive rod 3, a coil 4, a bobbin 5, an end cover 6, a screw 7, and a flexible hinge 8. Counterweight 9, disc spring 10, input push rod 11, pre-tightened screw rod 12 and wire hole 13. The flexible hinge 8, the counterweight 9, the disc spring 10 and the input jack 11 constitute the vibration collection module. By adjusting the distance between the counterweight, the input jack and the nodes of the flexible hinge, the pressure can be amplified by different multiples to act on the ultra- The magnetostrictive rod a...

Abstract

The invention discloses a super magnetostriction vibration energy collector for carrying out amplification through a flexible hinge. The super magnetostriction vibration energy collector is composed of a vibration collecting module for collecting outer vibration and an energy conversion module. The vibration collecting module is mainly composed of a balance weight, the flexible hinge, a belleville spring and an input ejector rod. The energy conversion module is mainly composed of a super magnetostriction stick, a coil, a coil framework and a permanent magnet. The energy collector is fixed on a vibration source; when the vibration source works, the balance weight vibrates because of inertia, the flexible hinge amplifies the pressure exerted on the input ejector rod, and the input ejector rod transmits the pressure to the super magnetostriction stick to enable the super magnetostriction stick to compress and deform; the magnetization intensity of the super magnetostriction stick changes; the change of the surrounding magnetic field can enable a closing coil to produce induced electromotive force based on the law of electromagnetic induction, and the electric energy on the coil can be led to an external circuit through a wire to be stored. The super magnetostriction vibration energy collector is simple and compact in structure, prone to microminiaturization, high in sensitivity to mini-vibration and stable and reliable in work.

Description

technical field [0001] The invention relates to an energy collection device, in particular to a giant magnetostrictive vibration energy collector amplified by a flexible hinge. Background technique [0002] In recent years, with the rapid development of micro-electro-mechanical technology, more and more microelectronic products have appeared in people's production and life. The size of microelectronic systems has become smaller and smaller, and the power consumption has become lower and lower. With the increasing complexity of the application environment of microelectronic devices and the diversification of application fields, people put forward higher requirements on the performance of all aspects of the device, especially the sustainability of the system. Conventional chemical batteries are limited in application in microelectronic systems due to their short life, limited energy storage, and severe pollution. Moreover, in some environments that are inaccessible and inacce...
