Description

Technical Field

[0001] The present invention belongs to the technical field of electrical and electronic switches, and particularly relates to a self-resetting power generation device. Background Art

[0002] With the rapid development of modern households, in order to save the cumbersome steps of switch wiring, passive switch controllers have gradually emerged on the market. Usually, it is achieved by an internal battery or a self-power generation module. Among them, the self-power generation module has the advantages of environmental protection and long service life, and has a better market prospect. Currently, the wireless kinetic energy switches on the market use the self-power generation module to provide the electrical energy required by the signal processing device through pressing, and then control the corresponding equipment through wireless signal transmission.

[0003] In the prior art, the power generation device of the self-power generation switch usually uses energy storage components such as springs to achieve reset, so as to ensure the accuracy of the subsequent signal transmission of the switch. However, there are the following problems: Under the pressure state, the spring will generate a corresponding elastic force to hinder its movement, and the greater the pressure, the greater the elastic force. Under the elastic buffer of the metal shrapnel of the self-power generation module, its instantaneous speed will be reduced, thereby reducing the generated voltage; and after obvious force application and long-term use, the spring will have a fatigue life, affecting the subsequent power generation amount and normal use. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a self-resetting power generation device, aiming to solve the problems mentioned in the background art.

[0005] The embodiments of the present invention are implemented as follows. A self-resetting power generation device includes a base, a key board buckled on the base, a gland located between the base and the key board and forming a limiting space with the base, a metal pressing plate located in the limiting space, a self-power generation module with a metal dial, and a PCB board electrically connected to the self-power generation module and having a tactile switch. A limiting seat for fixing the self-power generation module and a rotating support seat for fixing the metal pressing plate are provided in the base:

[0006] A pressing part is provided in the metal pressing plate on one side of the metal dial;

[0007] A first pressing column and a second pressing column for applying pressing forces to the metal pressing plate and the tactile switch respectively are provided in the key board; the metal pressing plate rotates with the rotating support seat as a fulcrum under the action of the first pressing column, and then presses the metal dial through the pressing part;

[0008] A magnet is provided on one side of the metal pressing plate for returning the metal pressing plate that has disengaged from the action of the key board to its original position.

[0009] Preferably, a plurality of magnet baffles for fixing the magnets are provided in the base; and the magnets are arranged in the plurality of magnet baffles.

[0010] Preferably, a rotating shaft rotatably arranged on the base is provided on one side of the key panel.

[0011] Preferably, a rotation hole is provided in the base; the key plate is rotatably disposed in the rotation hole through the rotating shaft.

[0012] Preferably, a through hole is provided on the pressure cover; the first pressing column passes through the through hole and abuts against the metal pressing plate.

[0013] Preferably, the metal pressing plate is provided with a rotating part which is rotatably fixed in the rotating support seat.

[0014] Preferably, the gland is fixedly arranged on the base.

[0015] Preferably, the key panel is provided with at least one key.

[0016] The working principle of the present invention is as follows:

[0017] (1) Initial state: The left side of the metal pressing plate is in contact with the magnet, the right side is located above the metal pick and has a certain gap with the metal spacer, and the metal pick is located on the self-generating module;

[0018] (2) Working state: The user presses the right side of the keypad to cause the keypad to move downward. The first pressing column on the keypad applies pressing force to the right side of the metal pressing plate. Under the action of the pressing force, the metal pressing plate rotates with the rotating support seat as the fulcrum. At this time, the right half of the metal pressing plate moves downward. The pressing part on the metal pressing plate pushes the metal paddle downward, and the magnetic flux inside the self-generating module changes accordingly, generating electric energy. The second pressing column on the keypad presses the touch button on the PCB downward, so that the PCB and the self-generating module form a path, and then transmits a control signal to the receiving device through circuit energy storage processing and signal processing.

[0019] (3) Recovery state: When the external force is no longer applied, the left side of the metal pressing plate moves downward under the suction of the magnet, causing the metal pressing plate to rotate again with the rotating support seat as the fulcrum. The rotation direction this time is opposite to the rotation direction in the working state. The right half of the metal pressing plate moves upward until the metal pressing plate returns to its initial state. The limit space is used to limit the movable travel of the metal pressing plate. At this time, the metal pick is separated from the metal pressing plate and also rebounds to its initial state.

[0020] An automatic reset power generation device provided by an embodiment of the present invention rotatably arranges a metal pressing plate on a rotating support seat to form a lever structure. When the device works, the metal pressing plate rotates with the rotating support seat as the fulcrum to press down the metal dial, enabling the self-power generation module to generate electric energy; during reset, by attracting the other end of the metal pressing plate with a magnet, the metal pressing plate rotates in the reverse direction with the rotating support seat as the fulcrum, thereby completing the reset operation of the metal pressing plate and the metal dial. The present invention changes the existing method of using a spring to reset the metal dial. The attractive force of the magnet on the metal dial does not change with the change of the pressing force. The generated voltage of the self-power generation module always remains stable, and the service life of the magnet is longer than that of the spring, and the service life of the automatic reset power generation device using a spring is also extended accordingly.

[0021] The structure of the present invention is simple, the design of each component is reasonable, and it occupies little space. It can achieve remote wireless transmission, and there is no need to wire the wall switch, which is convenient for the installation of switches in new houses and the transformation of switch wiring in old houses. It converts mechanical energy into electrical energy by using the habitual action of people pressing the switch with their fingers and emits a radio frequency control signal, without the need for a battery energy storage device.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0033] As shown in the attached Figures 1 to 4 and Fig. 8, a self-resetting power generation device provided by an embodiment of the present invention includes a base 1, a button board 2 buckled on the base 1, a pressing cover 3 located between the base 1 and the button board 2 and forming a limiting space with the base 1, a metal pressing plate 4 located in the limiting space, a self-power generation module 5 with a metal slider 51, and a PCB board 7 electrically connected to the self-power generation module 5 and having a tact switch 71. A limiting seat 12 for fixing the self-power generation module 5 and a rotating support seat 11 for fixing the metal pressing plate 4 are provided in the base 1:

[0034] A pressing part 41 is provided in the metal pressing plate 4 on one side of the metal slider 51;

[0035] A first pressing column 21 and a second pressing column 22 for applying pressing forces to the metal pressing plate 4 and the tact switch 71 respectively are provided in the button board 2; the metal pressing plate 4 rotates with the rotating support seat 11 as a fulcrum under the action of the first pressing column 21, and then presses the metal slider 51 through the pressing part 41;

[0036] A magnet 6 is provided on one side of the metal pressing plate 4 to return the metal pressing plate 4 that is separated from the action of the button board 2 to its original position.

[0037] In practical applications, the working principle of the self-resetting power generation device is as follows:

[0038] Initial state: The left side of the metal pressing plate 4 is in contact with the magnet 6, the right side is located above the metal slider 51 and has a certain gap from the metal spacer, and the metal slider 51 is located on the self-power generation module 5;

[0039] (2) Working state: the user presses the right side of the keypad 2, causing the keypad 2 to move downward. The first pressing column 21 on the keypad 2 applies pressing force to the right side of the metal pressing plate 4. Under the action of the pressing force, the metal pressing plate 4 rotates with the rotating support seat 11 as a fulcrum. At this time, the right half of the metal pressing plate 4 moves downward, and the pressing portion 41 on the metal pressing plate 4 pushes the metal paddle 51 downward. The magnetic flux inside the self-generating module 5 changes accordingly, generating electric energy. The second pressing column 22 on the keypad 2 pushes the touch button 71 on the PCB board 7 downward, so that the PCB board 7 and the self-generating module 5 form a path, and then transmits a control signal to the receiving device through circuit energy storage processing and signal processing.

[0040] (3) Recovery state: When the external force is no longer applied, the left side of the metal pressing plate 4 moves downward under the suction of the magnet, so that the metal pressing plate 4 rotates again with the rotating support seat 11 as the fulcrum. The rotation direction this time is opposite to the rotation direction in the working state. The right half of the metal pressing plate 4 moves upward until the metal pressing plate 4 returns to the initial state. The limit space is used to limit the movable stroke of the metal pressing plate 4. At this time, the metal pick 51 is separated from the metal pressing plate 4 and also rebounds to the initial state.

[0041] The present invention forms a lever structure by rotatably setting the metal pressing plate 4 on the rotating support seat 11. When the device is working, the metal pressing plate 4 rotates with the rotating support seat 11 as a fulcrum to press down the metal pick 51, so that the self-generating module 5 generates electricity; when resetting, the metal pressing plate 4 rotates in the opposite direction with the rotating support seat 11 as a fulcrum by using the magnet 6 to attract the other end of the metal pressing plate 4, thereby completing the resetting operation of the metal pressing plate 4 and the metal pick 51. The present invention changes the existing method of using a spring to reset the metal pick 51. The attraction of the magnet 6 to the metal pick 51 will not change with the change of the pressing force. The power generation voltage of the self-generating module 5 is always kept stable, and the service life of the magnet 6 is longer than that of the spring, and the service life of the self-resetting power generation device using a spring is also extended accordingly.

[0042] The present invention has a simple structure, reasonable design of components, and small space occupation. It can realize remote wireless transmission, does not require wiring for wall switches, is convenient for switch installation in new houses and modification of switch wiring in old houses, utilizes the habitual action of people's fingers when pressing switches to convert mechanical energy into electrical energy, and emits radio frequency control signals, without the need for battery energy storage devices.
