Specifically, as shown in FIG. 1-2 , the inner side of the first permanent magnet 311 in this embodiment is the N pole, and the outer side is the N pole. S pole, the inner side of the second permanent magnet 313 is the S pole, and the outer side is the N pole, so the first contact portion 3121 corresponds to the S pole, and the second contact portion 3141 corresponds to the N pole, and the two are magnetically opposite.

在初始状态下，如图1所示，软磁板1的上端与第一接触部3121接触，下端与避让口321接触，磁场方向由第一永磁体311的内侧经过软磁架3，再自下而上经过软磁板1，最后由第一接触部3121回到第一永磁体311的外侧，形成第一闭合磁路；而当软磁板1转动后，如图2所示，软磁板1的上端与第二接触部3141接触，下端与避让口321接触时，磁场方向由第二永磁体313的外侧经过第二导磁板314，再自上而下经过软磁板1，最后由软磁板1回到第二永磁体313的内侧，形成第二闭合磁路，第一闭合磁路中经过软磁板1的磁感线方向与第二闭合磁路中经过软磁板1的磁感线方向相反。这样在软磁板1转动后，软磁板1内的磁场方向发生了变化，软磁板1内的磁感线从有到无再到有，使得线圈2内产生感应电流，将软磁板1转动产生的机械能转换为电能，便可实现发电，而且由于形成为闭合磁路，使得机械能转换为电能的转换效率高，从而使得整体发电结构发电效率高，感应电流大。In the initial state, as shown in FIG. 1 , the upper end of the soft magnetic plate 1 is in contact with the first contact portion 3121 , and the lower end is in contact with the escape opening 321 . It passes through the soft magnetic plate 1 from bottom to top, and finally returns to the outside of the first permanent magnet 311 from the first contact part 3121 to form a first closed magnetic circuit; and when the soft magnetic plate 1 rotates, as shown in FIG. 2 , the soft magnetic When the upper end of the plate 1 is in contact with the second contact portion 3141, and the lower end is in contact with the escape opening 321, the direction of the magnetic field is from the outside of the second permanent magnet 313 through the second magnetic conductive plate 314, and then through the soft magnetic plate 1 from top to bottom, and finally. From the soft magnetic plate 1 back to the inside of the second permanent magnet 313, a second closed magnetic circuit is formed. The magnetic field lines are in opposite directions. In this way, after the soft magnetic plate 1 rotates, the direction of the magnetic field in the soft magnetic plate 1 changes, and the magnetic field lines in the soft magnetic plate 1 change from existence to non-existence, so that an induced current is generated in the coil 2, and the soft magnetic plate 1. The mechanical energy generated by the rotation can be converted into electrical energy, and power generation can be realized, and because it is formed as a closed magnetic circuit, the conversion efficiency of mechanical energy into electrical energy is high, so that the overall power generation structure has high power generation efficiency and large induced current.

当然，也可以将第一接触部3121配置成N极，第二接触部3141配置成S极，如图3所示，本实施例的另一实施方式中，第一永磁体311的内侧为S极，外侧为N极，而第二永磁体313的内侧为N极，外侧为S极。Of course, the first contact portion 3121 may also be configured as an N pole, and the second contact portion 3141 may be configured as an S pole. As shown in FIG. 3 , in another implementation of this embodiment, the inner side of the first permanent magnet 311 is S The outer side is the N pole, while the inner side of the second permanent magnet 313 is the N pole, and the outer side is the S pole.

由上述内容可知，本实施例的发电结构，在初始状态下，软磁板1静止不动，经过软磁板1的磁感线数量不变，磁场不发生变化，线圈2内便不会感应出电流，而当软磁板1转动后，经过软磁板1的磁感线数量发生变化，磁感线从有到无再到有，产生了变化的磁场，那么线圈2内便会开始产生电流，本实施例将软磁板1的机械能转换为电能，实现发电，使用方便。本实施例的发电结构应用在无线开关上时，可实现自发电，无需安装电池，而且磁路简单，制造方便、成本低。It can be seen from the above content that, in the power generation structure of this embodiment, in the initial state, the soft magnetic plate 1 is stationary, the number of magnetic lines of induction passing through the soft magnetic plate 1 does not change, the magnetic field does not change, and the coil 2 does not induce induction. When the soft magnetic plate 1 rotates, the number of magnetic field lines passing through the soft magnetic board 1 changes, and the magnetic field lines change from existence to non-existence, resulting in a changing magnetic field, then the coil 2 will begin to generate Electric current, in this embodiment, the mechanical energy of the soft magnetic plate 1 is converted into electrical energy to achieve power generation, which is convenient to use. When the power generation structure of this embodiment is applied to a wireless switch, self-power generation can be realized without installing a battery, and the magnetic circuit is simple, convenient to manufacture, and low cost.

In this embodiment, the soft magnetic frame 3 is arranged in an L shape, and the first permanent magnet 311 and the second permanent magnet 313 are arranged on the same side of the vertical part of the L shape. The way in which the first permanent magnet 311 and the second permanent magnet 313 are respectively arranged on both sides of the plate 1 reduces the size of the entire power generation structure in the transverse direction, making the structure more compact. In practical application, the horizontal direction of the power generation structure in this embodiment is equivalent to the thickness direction of the wireless switch.
