[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0031] Please refer to Figures 1 to 9The utility model discloses a self-generating wireless switch, which includes a shell 1, a pressure plate 4, a circuit board 2 and a power generation module 3 arranged in the shell, a connecting portion 11 is provided in the shell, and a first through hole 14 is opened on the shell; the power generation module 3 is electrically connected to the circuit board 2, and a communication module is provided on the circuit board 2; the pressure plate is rotatably connected to the connecting portion, and a downwardly protruding support portion 41 is provided on the pressure plate, which conflicts with the power generation module, and at least part of the pressure plate is located in the first through hole.

[0032] As can be seen from the above description, the beneficial effect of the present invention lies in that by pressing down on the pressure plate 4, the power generation module 3 can generate electricity, rendering the self-generating wireless switch of the present invention battery-free, thus resolving the problem of frequent battery replacement required in existing wireless switches. Furthermore, because the power generation module 3 is electrically connected to the circuit board 2, and the circuit board 2 is provided with a communication module, the power generation module 3 provides power to the circuit board 2. The communication module on the circuit board 2 can then transmit control signals (such as light-on signals and brightness adjustment signals) to lighting fixtures, thereby enabling on / off control of the lighting fixtures. This means that self-generated electricity is achieved, eliminating the need for batteries and wiring between the switch and the lighting fixture, thus reducing the corresponding wiring layout.

[0033] Furthermore, in the self-generating wireless switch described in the present invention, a plurality of support arms 42 are provided on the pressure plate 4 , and the plurality of support arms 42 are arranged at one end of the pressure plate 4 close to the connecting portion 11 , and the support arms 42 are rotatably connected to the connecting portion 11 .

[0034] As can be seen from the above description, a support arm 42 rotatably connected to the housing 1 is provided on the pressing plate 4, thereby realizing the rotatable connection of the pressing plate 4 so as to perform pressing to generate electricity.

[0035] Furthermore, in the self-generating wireless switch described in the present utility model, a pin shaft is provided on the support arm, and a pin hole is provided on the connecting portion, wherein the pin shaft is rotatably arranged in the pin hole.

[0036] As can be seen from the above description, a pin is provided on the support arm, and a pin hole is provided on the connecting portion, so that the pin is inserted into the pin hole, thereby realizing the rotatable connection of the pressure plate.

[0037] Furthermore, in the self-generating wireless switch of the present invention, a first through hole 14 corresponding to the pressing plate 4 is provided on the housing 1 , and at least a portion of the pressing plate 4 is located in the first through hole 14 .

[0038] It can be seen from the above description that the first through hole 14 is opened on the housing 1 so that the pressing plate 4 is not surrounded by the housing 1 , so as to press the pressing plate 4 .

[0039] Furthermore, the self-generating wireless switch of the present invention further includes a magnet 5 , which is disposed inside the housing 1 .

[0040] As can be seen from the above description, a magnet 5 is provided in the housing 1 to facilitate magnetic adsorption. The self-generating wireless switch is handheld and can be easily misplaced after use, leading to loss of the switch. The addition of a magnetic adsorption function allows the user to conveniently take and store the switch.

[0041] Furthermore, in the self-generating wireless switch of the present invention, the housing 1 includes an upper housing 12 and a lower housing 13 , and the upper housing 12 and the lower housing 13 are detachably connected.

[0042] As can be seen from the above description, the housing 1 includes an upper shell 12 and a lower shell 13 that are detachably connected, which facilitates the assembly and disassembly of the self-generating wireless switch.

[0043] Furthermore, in the self-generating wireless switch described in the present invention, the pressure plate 4 is provided with a claw 43 at one end away from the support arm 42, and a limiting portion 15 is provided in the lower shell 13. The limiting portion 15 and the lower shell 13 together form a movable channel, and the claw 43 is movably arranged in the movable channel.

[0044] From the above description, it can be seen that a limiting portion 15 is set in the lower shell 13, and a claw 43 is set at the end of the pressure plate 4 away from the support arm 42, so that when the pressure plate 4 is pressed and reset, the claw 43 can move up and down in the moving channel, which is convenient for limiting.

[0045] Furthermore, in the self-generating wireless switch of the present invention, a plurality of fixing members 16 are provided in the lower shell 13 , and the fixing members 16 are in conflict with the power generation module 3 .

[0046] As can be seen from the above description, a plurality of fixing members 16 are provided in the lower shell 13 , so as to facilitate the positioning and fixing of the power generation module 3 in the lower shell 13 through the plurality of fixing members 16 .

[0047] Furthermore, in the self-generating wireless switch of the present invention, the power generation module 3 includes a power generation board body 31 and a rotating arm 32, the power generation board body is provided with a coil 36, the rotating arm is rotatably provided on the power generation board body, and the rotating arm is provided with a magnetic rod 35. Figure 9 As shown, there are two magnetic bars, and an extension portion is provided on one side of the rotating arm close to the power generation plate body, and both magnetic bars are connected to the extension portion of the rotating arm.

[0048] In practice, after pressing plate 4 is pressed, it moves downward, driving rotating arm 32 to rotate downward, which in turn drives magnetic rod 35 connected to the rotating arm. This magnetic rod 35 generates a magnetic field. Correspondingly, since coil 36 (e.g., a copper coil) is provided on the main body of the power generation panel, when the rotating arm drives magnetic rod 35 to rotate downward, the movement of the magnetic rod can be seen as the copper coil cutting through the magnetic flux lines passing through it, causing the magnetic flux within the copper coil to change. This change in magnetic flux generates an electromotive force (voltage) within the copper coil, causing the power generation module to generate a corresponding current to power circuit board 2. Circuit board 2 also includes a communication module that can transmit control signals (e.g., a light-on signal or a brightness adjustment signal) to the corresponding lighting fixture.

[0049] Furthermore, the self-generating wireless switch described in the present invention also includes an axle pin 33 and an elastic arm 34. The power generation board body 31 and the rotating arm 32 are rotatably connected through the axle pin 33. The elastic arm 34 is arranged on the axle pin 33, and one end of the elastic arm 34 is connected to the power generation board body 31, and the other end is connected to the rotating arm 32.

[0050] As can be seen from the above description, the provision of a corresponding elastic arm 34 (e.g., a double torsion spring) enables the pressure plate 4 to automatically return to its unpressed state. Specifically, after being pressed, the pressure plate 4 moves downward, causing the pivoting arm 32 to also rotate downward. The end of the elastic arm 34 connected to the pivoting arm 32 rotates downward along with the pivoting arm 32. When the pressing operation is completed, the elastic arm 34 returns to its initial state, simultaneously driving the pivoting arm 32 to return to its initial state, and thus driving the pressure plate 4 to its unpressed state.

[0051] Furthermore, in the self-generating wireless switch of the present invention, a second through hole 21 is provided on the circuit board 2 , and the supporting portion 41 passes through the second through hole 21 and contacts the rotating arm 32 .

[0052] From the above description, it can be seen that since the circuit board 2 is arranged on the power generation module 3, in order to enable the pressure plate 4 to drive the rotating arm 32 to rotate when being pressed to cut the magnetic steel wire to generate current, the utility model sets a second through hole 21 on the circuit board 2 so that the support part 41 can pass through the second through hole 21 and abut against the rotating arm 32.

[0053] Please refer to Figures 1 to 9 The first embodiment of the present invention is a self-generating wireless switch that generates its own electricity, eliminating the need for batteries or wiring, and can control lighting fixtures on and off, adjust their brightness, and perform other operations. The self-generating wireless switch comprises, from top to bottom, an upper housing 12, a pressure plate 4, a circuit board 2, a power generation module 3, and a lower housing 13. These components are described in detail below with reference to the accompanying figures.

[0054] In this embodiment, if Figure 2 as well as Figure 3 As shown, the upper shell 12 is detachably mounted on the lower shell 13 to form a receiving cavity. The upper shell 12 is provided with a first through hole 14 corresponding to the pressure plate 4. The pressure plate 4 is partially disposed in the receiving cavity and partially extends out of the receiving cavity through the first through hole 14, so that the user can press the pressure plate 4. Four positioning members 17 are provided within the lower shell 13. The four positioning members 17 extend upward from the bottom of the lower shell 13. When the upper shell 12 and the lower shell 13 are assembled, these four positioning members can be used to position them, facilitating quick installation.

[0055] In this embodiment, if Figures 2 to 5 As shown, a circuit board 2 and a power generation module 3 are provided in the housing 1. The power generation module 3 is arranged at the bottom of the inner cavity of the lower shell 13. Four fixing members 16 are provided at the bottom of the inner cavity of the lower shell 13. The four fixing members 16 are provided with hooks. The hooks are clamped on the power generation module 3, thereby fixing the power generation module 3 to the bottom of the inner cavity of the lower shell 13. A limiting portion and a connecting portion 11 are also provided at the bottom of the inner cavity of the lower shell 13. The limiting portion and the connecting portion 11 are respectively located on both sides of the power generation module 3. The limiting portion is a U-shaped structure, which forms a U-shaped moving channel with the bottom of the lower shell 13. Correspondingly, as shown in FIG. Figure 8 As shown, one end of the pressure plate 4 is provided with a claw 43, which is movably disposed in the movable channel. There are two limiting portions, each of which is provided with a pin hole 18. Correspondingly, the pressure plate 4 is provided with two supporting arms 42 at the end away from the claw 43. The tail ends of the two supporting arms 42 are provided with pins 44, which are disposed in the pin holes 18 to facilitate relative rotation of the pressure plate 4. In addition, the lower shell 13 is provided with a mounting portion 19 near the two limiting portions. This mounting portion is similar to a ring-shaped object, and the circular magnet 5 is disposed in this mounting portion 19.

[0056] In this embodiment, if Figure 7 as well as Figure 9As shown, the power generation module 3 includes a power generation board body 31 and a rotating arm 32. The rotating arm 32 and the power generation board body 31 are rotatably connected via a rotating shaft. Furthermore, the power generation module 3 includes a double torsion spring secured to the rotating shaft. A retaining ring in the middle of the double torsion spring abuts against the power generation board body 31, and its legs at both ends are connected to the rotating arm 32. Furthermore, it should be noted that the circuit board 2 is electrically connected to the power generation module 3. The circuit board 2 is partially disposed on the power generation module 3 and partially suspended above the magnet 5. A communication module is provided on the circuit board 2 so that when the power generation module 3 supplies power to the circuit board 2, it can generate corresponding control signals to issue commands to lighting fixtures, such as turning on or off the light, or increasing the brightness. The circuit board 2 also has a second through-hole 21, through which the support portion 41 passes and abuts against the rotating arm 32.

[0057] In summary, the self-generating wireless switch provided by the present invention has the following features: (1) The pressure plate is provided with a support arm, and the pin at the tail of the support arm is fixed to the pin hole of the lower shell connection part, and uses it as a rotation support point. The pressure plate rotates around the pin. When pressed, the pressure plate moves slightly. Each time it is pressed, electricity is generated. The generated electricity is transmitted wirelessly, and the circuit board performs voltage conversion. (2) The self-generating wireless switch of the present invention can generate electricity by itself, does not require batteries, does not require wiring, and can be laid out without wiring. In addition, the self-generating wireless switch of the present invention also has a dimming function. If you press and hold it, the light of the lighting fixture can be infinitely changed from the darkest to the brightest. On the other hand, the self-generating wireless switch of the present invention also has a dimming function. If you press and hold the pressure plate 4, the light of the lighting fixture can be infinitely changed from the darkest to the brightest, which is convenient for adjusting the brightness of the lighting fixture. In actual applications, the press command is different from the raise command. When the receiver receives the press command, it means dimming, and the raise command means the end of dimming. If the interval between the press command and the raise command is within 500 milliseconds, it is considered as the light turning on command.
