本实用新型的工作原理：Working principle of the utility model:

如图3和图4所示，两个运动件2中的两组永磁体201面对固定件塑料框架105的磁极相反，即若一个运动件2中的永磁体201面向固定件塑料框架105的为N极，则另一个运动件2中永磁体201面向固定件塑料框架105的为S极，这样两个运动件2的马蹄形磁体可与固定件塑料框架105的上磁芯101和中磁芯102或中磁芯102和下磁芯103构成一个完整的环形磁路。As shown in Figures 3 and 4, the magnetic poles of the two groups of permanent magnets 201 in the two moving parts 2 facing the plastic frame 105 of the fixing part are opposite, that is, if the permanent magnets 201 in one moving part 2 face the plastic frame 105 of the fixing part If it is an N pole, then the permanent magnet 201 in the other movable part 2 is an S pole facing the plastic frame 105 of the fixed part, so that the horseshoe magnets of the two movable parts 2 can be connected with the upper magnetic core 101 and the middle magnetic core of the plastic frame 105 of the fixed part. 102 or the middle magnetic core 102 and the lower magnetic core 103 form a complete ring magnetic circuit.

如图1、图2、图3和图4所示，在按键3、杠杆4和回复弹簧5的作用下，运动件2在上磁芯101和中磁芯102与中磁芯102和下磁芯103之间运动，使中磁芯102内通过的磁感线反向，因而，绕制在中磁芯102上的感应线圈104内会产生感应电动势。As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, under the action of the button 3, the lever 4 and the return spring 5, the moving part 2 moves between the upper magnetic core 101 and the middle magnetic core 102 and the middle magnetic core 102 and the lower magnetic core. The movement between the cores 103 reverses the magnetic field lines passing through the middle magnetic core 102 , thus, an induced electromotive force will be generated in the induction coil 104 wound on the middle magnetic core 102 .

当永磁体和磁芯的截面相对齐时，即分别处于图3和图4所示位置时，永磁体—磁芯—永磁体—磁芯构成了一个闭合的磁环，气隙小、漏磁率小，提高了磁场的利用率。When the cross-sections of the permanent magnet and the magnetic core are aligned, that is, when they are in the positions shown in Figure 3 and Figure 4, the permanent magnet-magnetic core-permanent magnet-magnetic core forms a closed magnetic ring with a small air gap and a magnetic flux leakage rate. Small, improving the utilization of the magnetic field.

如图1、图2和图3所示，当按键3未按下时，运动件2处于图3的位置，此时通过中磁芯102和感应线圈104的磁感线由左向右；按键3按下后，运动件2向下运动，并最终达到图4所示位置，此时通过中磁芯102和感应线圈104的磁感线由右向左。从按键3未按下到完全按下后，通过感应线圈104的磁感线发生了反向，即通过感应线圈104的磁通量发生了变化，根据电磁感应原理，感应线圈104中将产生感应电动势，此感应电动势可由电容进行能量收集，作为某些低功耗应用电路的供电源。此发明装置可将按键的机械能转化为电能存储和使用，使无线开关等产品无须电池供电即可使用。As shown in Fig. 1, Fig. 2 and Fig. 3, when the button 3 is not pressed, the moving part 2 is in the position of Fig. 3, and the magnetic field lines passing through the middle magnetic core 102 and the induction coil 104 are from left to right at this moment; 3 After being pressed, the moving part 2 moves downwards, and finally reaches the position shown in FIG. 4 , at this time, the magnetic field lines passing through the middle magnetic core 102 and the induction coil 104 are from right to left. After the button 3 is not pressed to fully pressed, the magnetic induction lines passing through the induction coil 104 are reversed, that is, the magnetic flux passing through the induction coil 104 changes. According to the principle of electromagnetic induction, an induced electromotive force will be generated in the induction coil 104, This induced electromotive force can be energy-harvested by capacitors as a power source for some low-power application circuits. The inventive device can convert the mechanical energy of the button into electric energy for storage and use, so that products such as wireless switches can be used without battery power.

此外，本实施例说明中装置采用了动铁模式（即永磁体运动），但是动圈模式（即感应线圈运动）也属于本实用新型的另一实施例，涵盖在本实用新型的范围内。In addition, in the description of this embodiment, the device adopts the moving iron mode (that is, the movement of the permanent magnet), but the moving coil mode (that is, the movement of the induction coil) also belongs to another embodiment of the present invention, and is covered within the scope of the present invention.
