Description

Self-power generating apparatus capable of applying to 2 gang switch}

The present invention relates to a non-powered self-generating device used in a switch, and more particularly, to a non-powered self-generating device applicable to a two-prong switch.

The self-powered wireless switch generates power by itself without a separate external power source and uses it to generate an RF signal related to switching control.

For self-generation, piezoelectric and coil methods are generally used.

1 is an exploded perspective view of a self-generating device using a conventional coil method, and FIG. 2 is a combined perspective view of a self-generating device using a conventional coil method.

Referring to FIGS. 1 and 2, the self-generating device using the conventional coil method includes a first magnetic body 11, a coil 20, a second magnetic body 12, a first magnet 31, and a third magnetic body 13 and a fourth magnetic body 14.

The first magnetic body 11 extends to one side, and the coil 20 is wound around the center of the first magnetic body 11 . That is, one end of the first magnetic material 11 is exposed to one side. The second magnetic body 12 accommodates the first magnetic body 11 and the coil 20, and the first magnet 31, the third magnetic body 13, and the fourth magnetic body 14 are of the first magnetic body 11. placed on one side

3 and 4 show a cross-sectional schematic diagram of a self-generating device using a conventional coil method and the flow of magnetic flux in each state.

3A and 4A, a third magnetic body 13 and a fourth magnetic body 14 are disposed on the upper and lower surfaces of the first magnet 31, respectively. A configuration including the first magnet 31 , the third magnetic body 13 and the fourth magnetic body 14 is referred to as a switch module 41 .

The switch module 41 maintains a state of being rotated upward at a certain angle in a state in which no external force is applied by the user. In this state, the third magnetic body 13 is in contact with the upper end of the second magnetic body 12 serving as a case, and the fourth magnetic body 14 is in contact with the end of the first magnetic body 11, and at this time the magnetic flux is flowed as shown in FIG. 3B. When the user presses the switch module 41 and moves as shown in FIG. 4A, the third magnetic body 13 of the switch module 41 is in contact with the end of the first magnetic body 11, and the fourth magnetic body ( 14) is in contact with the lower end of the second magnetic body 12, and at this time, magnetic flux flows as shown in FIG. 4B. That is, while the user presses the switch module 41, the direction of the magnetic flux is changed, and thus the induced current flows.

Conventional self-generating devices of this type were mainly used as a device for generating a trigger signal, but since only one type of signal is generated when a single device is used, it serves as a switch to generate two different types of trigger signals. In order to do this, the number of self-generating devices corresponding to the number of switches is required, resulting in reduced economic feasibility and relatively bulky problems.
