Double-magnet button type self-generating apparatus

Abstract

The invention discloses a double-magnet button type self-generating apparatus. The apparatus comprises the mainly components of an iron core, a coil, magnets and magnet yokes; the coil is wound on a plastic member; the iron core penetrates the plastic member; two ends of the iron core are respectively disposed between two magnet yokes which are disposed at the left side and at the right side; the four magnet yokes are disposed at the left side and at the right side in pairs, and one magnet is clamped between each pair of two magnet yokes at each side; the N poles and the S poles of the two magnets at the left side and at the right side are arranged to be in opposite directions, i.e., if the N pole of the magnet at the left side is oriented upwards, the S pole of the magnet at the right side is oriented upwards; the magnets and the magnet yokes at the left side and at the right side are connected through non-magnetic-conductive materials so as to form an integral button capable of moving vertically relative to the iron core; and when the button moves vertically, the iron core contacts with the magnet yokes at upper positions and at lower positions separately, and since the magnets at the two sides are arranged in opposite directions, the magnetic induction line of the iron core are reversed during the contact process, the coil generates induction potential. According to the double-magnet button type self-generating apparatus of the invention, micro energy of the button is used for power generation. The double-magnet button type self-generating apparatus is simple in structure and small in size; and the double-magnet button type self-generating apparatus can be applied to components such a wireless switch which needs automatic power generation of a button.

Description

technical field [0001] The invention relates to a self-generating device, in particular to a key-type self-generating device with double magnets. Background technique [0002] With the development of technology, more and more daily products are going wireless and miniaturized, and the power supply problem has become a key problem that needs to be solved. For example, traditional switches are being replaced by wireless switches that can be remotely controlled, moved, and without wiring. At present, some wireless switches still use batteries to power the circuits in the switch. The battery life is limited and needs to be replaced after a certain period of time. Replacement, which affects the use of the switch to a certain extent, and waste batteries can also pollute the environment. In this application, the button-type self-generating device can convert the mechanical action of the switch button into electrical energy, thereby supplying power to the subsequent circuit. It sol...
