However, the internal space of a general kinetic energy switch is limited, and a spring structure needs to be arranged to reset the key for the parallel pressing switch, so that the size is not reduced.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a press swing type electromagnetic power generating structure, which further reduces the volume and generates a small amount of electric energy.

The technical scheme of the utility model is as follows: the utility model provides a press oscillating electromagnetism power generation structure, includes the base, presses support, two permanent magnets, three soft magnet and induction coil, the soft magnet in proper order parallel arrangement superpose in the base, the interval sets up between the soft magnet, induction coil is around locating the soft magnet that is located in the middle of being located, press the support with the base is articulated, press the support with the articulated shaft of base with induction coil establish range upon range of orientation perpendicular around, two permanent magnets set up in press the support about the both ends side of waning and be located the both ends side of three soft magnet, two the magnetic pole syntropy of permanent magnet sets up, press the support from top to bottom the waning make two permanent magnets form magnetic path with the soft magnet that is located the top and middle and with being located middle and bottom respectively.

Further, in order to keep the permanent magnet in a relatively parallel state as much as possible when the pressing bracket tilts up and down, suspension brackets are respectively hinged to both end sides of the upward and downward tilting of the pressing bracket, and the permanent magnet is fixedly mounted on the suspension brackets.

Further, a hinge axis of the suspension bracket and the pressing bracket is parallel to a hinge axis of the pressing bracket and the base.

Furthermore, in order to enable the suspension bracket to be more stably kept vertical when moving up and down, limiting grooves are formed in the two end sides of the soft magnet on the base, and the suspension bracket moves up and down in the limiting grooves when the pressing bracket tilts up and down.

Further, the three soft magnets are uniform in size, and the distances between the soft magnets are equal.

Further, the length of the permanent magnet is not more than the distance between the back surfaces of the adjacent soft magnets.

Further, the magnetic pole direction of the permanent magnet is perpendicular to the winding and stacking direction of the induction coil.

Compared with the prior art, the utility model has the advantages that:

when the button is pulled to the termination state, the N pole and the S pole which are opposite to the coil are exchanged, the direction of the magnetic field is changed, and induced electromotive force is generated in the coil to prevent the change of the magnetic field in the coil so as to generate electric energy.

Compared with the flat-pressing type pulling method adopting the bidirectional anti-parallel magnets, the method needs the two magnets to move in parallel when the bidirectional anti-parallel magnets are distributed, and the two magnets need to be installed in an anti-parallel mode when the structure is assembled. Pressing swing structure and comparing in pressing portable structure, mechanical structure is more firm and simple, and it is more smooth to reciprocate to stir, does not need extra elastic element. In addition, poking resistance inductance is realized by magnet attraction at the initial position and the final position of the button, and the double-magnetic-pole relative structure is stronger than a single-magnet magnetic field.
