Abstract

The invention discloses a multidirectional vibration energy recovery structure. The structure comprises a shell, a mass block, energy conversion strips, a permanent magnet and an electromagnetic coil, wherein the shell has a hollow solid structure, the mass block is positioned in the center of the shell and made of a soft magnetic material; the number of the energy conversion strips is in accordance with the number of vertexes of the shell; the mass block is connected with each vertex of the shell; the energy conversion strip consists of a preflex elastic material core layer and at least one piezoelectric material layer, and energy collecting electrodes are distributed on the piezoelectric material layer; and the permanent magnet is made of a strong magnetic material and fixed inside the mass block, and the electromagnetic coil is fixed on the outer surface of the shell. The structure can collect vibration energy in high efficiency in spite of the change of the vibration direction or in a multidirectional vibration environment.

Description

technical field [0001] The invention belongs to the field of vibration energy collection, and relates to a structure for converting external vibration energy into electric energy, in particular to an energy collection structure capable of adapting to multiple directions in different vibration environments. Background technique [0002] With the rapid development of modern industry, environmental pollution and energy shortage are two major problems facing countries all over the world. In order to solve the impact of energy crisis on economic development and people's life, scientific and technological workers from various countries began to explore new green energy. Vibration is a common phenomenon in people's daily life. Due to its high energy density, its potential energy value has attracted more and more attention and thinking of scientific and technological researchers. [0003] As a kind of intelligent material, piezoelectric material has positive piezoelectric effect a...
