In addition, since the soft magnetic plate assembly 16 is disposed at the side of the coil support 11, the space at the side of the coil support 11 is large, and the soft magnetic plate 161 is not located inside the coil support 11 and is not shielded by the coil support 11, the soft magnetic plate assembly 16 can not only realize the deflection motion of the middle fulcrum two-end pressing type, but also realize the spring contact motion of the middle pressing type, so that the self-generating device of the present embodiment can be applied to switches in various pressing forms.

Further, the self-generating device of the embodiment further includes a fixing plate 17, an elastic component is disposed on the fixing plate 17, and in an initial state, the soft magnetic plate component 16 is simultaneously contacted with the contact port 141 and the second magnetic conduction plate 15 under the action of the elastic component to form a first closed magnetic circuit. Specifically, the fixed plate 17 is disposed at the bottom of the soft magnetic plate assembly 16, the fixed plate 17 is further provided with a first fixed portion 171 and a second fixed portion 172, the elastic assembly comprises a fixed shaft 173 and a torsion spring 174 disposed at the bottom of the soft magnetic plate assembly 16, wherein the fixed shaft 173 is fixed with the first fixed portion 171 and the second fixed portion 172, the torsion spring 174 is sleeved on the fixed shaft 173, the middle portion of the soft magnetic plate 161 is provided with a rotating shaft 1612, the soft magnetic plate 161 can rotate around the rotating shaft 1612, and the rotating shaft 1612 and the soft magnetic plate 161 can be selected and not limited to be integrally formed.

In the initial state, the torsion spring 174 presses against the first end of the soft magnetic plate 161 to make the soft magnetic plate assembly 16 contact with the contact port 141 and the second magnetic conductive plate 15 simultaneously. Specifically, the first permanent magnet 162 is disposed above the N pole, the second permanent magnet 163 is disposed below the N pole, and the first permanent magnet 162 is disposed above the N pole, and the second permanent magnet 163 is disposed below the S pole. In an initial state, the torsion spring 174 tightly pushes against the first end of the soft magnetic plate 161 to enable the soft magnetic plate 161 to contact with the upper end of the contact port 141 of the first magnetic conduction plate 14, and meanwhile, the first connecting magnetic plate 164 above the first permanent magnet 162 contacts with the second magnetic conduction plate 15 to form a first closed magnetic circuit of the first permanent magnet 162-the first connecting magnetic plate 164-the second magnetic conduction plate 15, and the intermediate magnetic plate 13-the first magnetic conduction plate 14-the soft magnetic plate 161-the first permanent magnet 162; after the first end of the soft magnetic plate 161 is pressed, the soft magnetic plate 161 rotates to contact with the lower end of the contact port 141 of the first magnetic conduction plate 14, and simultaneously, the second magnetic connection plate 165 below the second permanent magnet 163 contacts with the second magnetic conduction plate 15, so that a second closed magnetic circuit of the second permanent magnet 163, the soft magnetic plate 161, the first magnetic conduction plate 14, the middle magnetic plate 13, the second magnetic conduction plate 15, the second magnetic connection plate 165 and the second permanent magnet 163 is formed.

The self-generating device of the embodiment is not only suitable for a toggle switch of a both-end pressing type, but also suitable for a switch of a middle pressing type, such as a push button switch, by setting the middle part of the soft magnetic plate 161 as a pressing part.

Example three:

as shown in fig. 10 to 11, the present embodiment provides a self-generating device, which is different from the self-generating device of the first embodiment in the structure of the soft magnetic plate 161 and the elastic member, and the elastic member of the present embodiment includes a spring 176, and the spring 176 is disposed between the soft magnetic plate member 16 and the fixed plate 17. Specifically, the position-limiting sleeves 177 are disposed below the soft magnetic plate 161, below the second connecting magnetic plate 165 and above the fixing plate 17, and springs 176 are disposed in the position-limiting sleeves 177, so that the switching of the closed magnetic circuit can be performed by pressing the middle portion of the soft magnetic plate 161.

In the present embodiment, the first permanent magnet 162 is disposed above the N pole, the second permanent magnet 163 is disposed below the N pole, and the first permanent magnet 162 is disposed above the N pole. In an initial state, the spring 176 tightly pushes the soft magnetic plate assembly 16, so that the first end of the soft magnetic plate 161 is in contact with the upper end of the contact port 141 of the first magnetic conduction plate 14, and meanwhile, the second connecting magnetic plate 165 below the second permanent magnet 163 is in contact with the second magnetic conduction plate 15, so that a first closed magnetic circuit of the second permanent magnet 163, the soft magnetic plate 161, the first magnetic conduction plate 14, the middle magnetic plate 13 and the second magnetic conduction plate 15, the second connecting magnetic plate 165 and the second permanent magnet 163 is formed; after the middle of the soft magnetic plate 161 is pressed, the soft magnetic plate 161 moves downward to contact with the lower end of the contact port 141 of the first magnetic conduction plate 14, and meanwhile, the first connecting magnetic plate 164 above the first permanent magnet 162 contacts with the second magnetic conduction plate 15, so that a second closed magnetic circuit of the first permanent magnet 162, the first connecting magnetic plate 164, the second magnetic conduction plate 15 and the middle magnetic plate 13, the first magnetic conduction plate 14, the soft magnetic plate 161 and the first permanent magnet 162 is formed. Because the direction of the magnetic induction line passing through the middle magnetic plate 13 in the first closed magnetic circuit is opposite to the direction of the magnetic induction line passing through the middle magnetic plate 13 in the second closed magnetic circuit, current is induced in the coil 12, and power can be supplied to a radio frequency circuit board and the like.

Preferably, the number of the springs 176 of the present embodiment is two, and the springs are respectively disposed under the soft magnetic plate 161 and the second connecting magnetic plate 165, so that the soft magnetic plate 161 can be ensured to move up and down smoothly.

Further, the self-generating device of the present embodiment further includes a plurality of limiting plates 178, and the plurality of limiting plates 178 are respectively disposed around the soft magnetic plate assembly 16 to limit displacement of the soft magnetic plate assembly 16 in the front-rear and left-right directions. Specifically, as shown in fig. 10, two limiting plates 178 are respectively disposed at two ends of the soft magnetic plate 161 to limit displacement of the soft magnetic plate 161 in the left-right direction, i.e., in the length direction thereof, two limiting plates 178 are respectively disposed at two sides of the soft magnetic plate 161 to limit displacement of the soft magnetic plate 161 in the front-back direction, i.e., in the width direction thereof, so that smooth movement of the soft magnetic plate 161 can be further ensured. For convenience of installation, each of the stopper plates 178 and the fixed plate 17 are detachably attached.

The self-generating device of the embodiment is provided with the pressing portion at the middle portion of the soft magnetic plate 161, so that the soft magnetic plate 161 performs elastic contact motion, and is suitable for toggle switches of two-end pressing type and switches of middle pressing type such as push-button switches.
