Detailed Description

In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

In this embodiment, as shown in fig. 1, a swing piece 2 (a spring piece or a swing component with elasticity such as a spring) is installed on a fixed end 1, a heavy hammer 3 is installed on the end of the swing piece 2, and the heavy hammer 3 is connected with a magnet 4 which spans over a magnetic grid 5A and a magnetic grid 5B; a plurality of magnetic poles on the magnetic grids 5A and 5B are arranged in a staggered manner, and a power generation coil 6 is wound at the connecting end of the magnetic grids 5A and 5B;

the magnetic moment L of the magnet 4 and the pole pitch K of the magnetic grids 5A, 5B need to satisfy a certain relationship: the magnetic distance L is n and K + K/2, K is the magnetic grid distance, the magnetic poles of the two groups of magnetic grids are shifted by K/2, and n is a positive integer;

a proper gap is left between the magnet and the magnetic grid, so that the magnet is prevented from touching the magnetic pole in the free swinging process.

The working process of the invention is as follows:

when vibration occurs, the heavy hammer 3 swings to drive the magnet 4 to move together;

the magnet 4 and the magnetic grids 5A and 5B generate relative movement, because the magnet 4 straddles a pair of magnetic grids 5A and 5B, and the magnetic poles of the magnetic grids 5A and 5B are arranged in a staggered manner, as shown in fig. 2a and 2B, the magnetic poles a1\ a2.. An of the magnetic grid 5A and the magnetic poles B1\ B2.. Bn of the magnetic grid 5B are arranged in a staggered manner, taking the direction of An arrow as An example, the magnet 4 moves from the position shown in fig. 2a to the position shown in fig. 2B, moves by a magnetic grid pole distance K, continues to move, and magnetic lines of force alternately move from the magnetic grid 5A to the magnetic grid 5B and then from the magnetic grid 5B to the magnetic grid 5A;

a power generation coil 6 between the magnetic grids 5A and 5B for generating power by a change in magnetic flux; because there are many magnetic grids in a swing range, and every time cross a magnetic pole, the magnetic flux changes once alternately, so change the magnetic flux of the generating coil 6 many times in a swing range, the generating coil 6 also generates electricity many times; the magnetic flux change rate is greatly improved because the polar distance between the magnetic grids is greatly reduced; the higher the magnetic flux change rate in the coil is, the larger the generated energy is; within one swing, the number of magnetic poles is greatly increased, the change rate of magnetic flux is also greatly improved, and the two factors greatly improve the power generation efficiency of the vibrating magnetic grid generator.
