specific Embodiment 1

[0065] Such as figure 1 As shown in , the inductance coil 5 surrounds the outside of the magnetic field superposition mechanism 2 . When the magnetic field superimposed by at least two permanent magnets changes, the magnetic flux passing through the inductance coil 5 changes accordingly, thereby inducing electric energy.

[0066] Among the at least two permanent magnets in the magnetic field superposition mechanism 2 , besides a moving permanent magnet 3 , a fixed permanent magnet 6 is also included. During the movement of the moving permanent magnet 3 , the superimposition of the magnetic field of the moving permanent magnet 3 and the magnetic field of the fixed permanent magnet 6 changes, which in turn causes the magnetic field of the magnetic field superposition mechanism 2 to change. By arranging certain permanent magnets 6, the structure is simplified and the stability of the system is improved. The fixed permanent magnet 6 passes through the inductance coil 5 along the...

specific Embodiment 2

[0067] refer to figure 2 , An inductance coil 5 is arranged in front of at least one magnetic pole of the fixed permanent magnet 6 . When the magnetic field superposition of the fixed permanent magnet 6 and the moving permanent magnet 3 changes, the magnetic flux in the inductance coil 5 changes, thereby generating electric energy.

specific Embodiment 3

[0068] refer to image 3 , The magnetic field switching system 1 is provided with a support, the fixed permanent magnet 6 is fixed on the support, a rotating shaft is arranged above the middle part of the fixed permanent magnet 6, and the middle part of the moving permanent magnet 3 is rotatably connected with the rotating shaft. The fixed permanent magnet 6 is located on one side of the plane where the moving permanent magnet 3 rotates, and is arranged parallel to the plane. The inductance coil 5 is located above one pole of the fixed permanent magnet 6 and below the moving permanent magnet 3 .

[0069] When the moving permanent magnet 3 rotates, the magnetic poles of the same polarity as the fixed permanent magnet 6 are close to each other, and the magnetic flux passing through the inductance coil 5 is less at this time. When the moving permanent magnet 3 rotates, there will also be a situation where the magnetic poles of different polarities of the fixed permanent magnet 6...

Abstract

The invention discloses a magnetic field switching power supply and application thereof, which relate to the technical field of power generation. The magnetic field switching power supply comprises a magnetic field switching system. The magnetic field switching system comprises a magnetic field superposition mechanism, wherein the magnetic field superposition mechanism is provided with at least two permanent magnets; magnetic fields of the at least two permanent magnets are superposed to form the magnetic field of the magnetic field superposition mechanism; and one of the two permanent magnetis a movable permanent magnet which moves relatively. The magnetic field switching power supply further comprises an inductive coil. The magnetic field of the magnetic field superposition mechanism runs through the inductive coil, and the magnetic flux of the inductive coil is changed along with the change of the magnetic field of the magnetic field superposition mechanism when the magnetic fieldof the magnetic field superposition mechanism is changed to further inductively produce electric potential energy in the inductive coil. By such a design, an actuating system is driven by an externalforce to drive the movable permanent magnet to move, and the magnetic flux of the inductive coil is changed in the movement of the movable permanent magnet to further inductively produce electric energy in the inductive coil for electrical equipment to use.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to the field of power generation technology. Background technique [0002] Existing power generation devices are mainly generators, which are relatively large in size, and most of them generate electric energy through the high-speed rotation of the rotor, resulting in many limitations in use, so that they cannot be widely used. [0003] Piezoelectric ceramic power supply has the advantages of small size and simple power generation process, and has been used in daily life, such as lighters, stove igniters and other equipment. However, piezoelectric ceramics generate high voltages and extremely short current durations, making it difficult to power circuits. [0004] People need a power supply with simple structure, small size, simple power generation process, and easy power supply for circuits, so that it can be applied in a wider range of fields.
