Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 and figure 2 , The pressing self-generating device of the present invention includes a stator core 3, a rotor, a coil 4, a torsion spring 6, a first limiting device 7 and a second limiting device. The stator core 3 includes an upper cantilever and a lower cantilever arranged in parallel and an iron yoke between the upper and lower cantilever. The rotor includes an annular rotor core 5 and a first magnetic steel 1 and a second magnetic steel 2 fastened to the outer circumference of the rotor core 5 with opposite magnetic properties. The outer circumferential surface of the rotor core 5 has a protruding pressing piece. The pressing sheet can be produced integrally with the rotor core 5 . The coil 4 and the rotor core 5 are sequentially sleeved on the upper cantilever of the stator core 3 along a direction away from the iron yoke. One end of...

Abstract

The invention discloses a pressing self-generating device which comprises a stator iron core, a rotor iron core, first magnetic steel, second magnetic steel and a coil, wherein the magnetism of the first magnetic steel is opposite to the magnetism of the second magnetic steel, the coil is wound on the stator iron core, the rotor iron core can rotate around the center of the coil, and the first magnetic steel and the second magnetic steel are attached to the outer circumferential surface of the stator iron core. As the air gap is very small, a closed magnetic circuit can be formed between a cantilever of the stator iron core and the magnetic steel. By pressing a pressing sheet on the rotor iron core, the rotor iron core rotates, and the magnetic steel opposite to a stator cantilever is changed from the first magnetic steel into the second magnetic steel. The magnetic flux in the coil sleeving the stator iron core is changed from positive to negative (or from negative to positive), and the changed magnetic field induces voltage in the coil. Mechanical energy can be converted into electric energy to replace dry batteries in a remote controller, environmental pressure caused by use ofthe dry batteries is avoided, and the pressing self-generating device is compact in structure and convenient to install in various remote controllers.

Description

technical field [0001] The invention relates to the field of micro generators and power generating devices, in particular to a pressing self-generating device. Background technique [0002] The remote control is used to remotely control electronic devices, such as wireless doorbell switches, remote controls for household appliances, electronic car keys, etc., which brings great convenience to human life. Modern remote controllers are generally powered by dry batteries. On the one hand, the manufacture and destruction of dry batteries bring enormous pressure to the environment; Dry batteries that are used or idle for a long time are prone to overflow electrolyte, polluting household and equipment. Contents of the invention [0003] Purpose of the invention: In order to solve the problems existing in the prior art, the present invention provides a pressing self-generating device. [0004] Technical solution: The pressing self-generating device of the present invention incl...
