[0023] Referring to Figure 1 、 2 、3, and 4, the piezoelectric ceramic self-powered remote control switch includes a switch housing, a button 2, a remote control circuit, and a power source. The power source uses a piezoelectric magnetic adsorption self-powered power source.

[0024] The piezoelectric magnetic adsorption self-powered power source includes a bracket 1 and also includes a movable button 2 assembled on the bracket 1.

[0025] It also includes a piezoelectric material sheet.

[0026] The piezoelectric material sheet uses a piezoelectric ceramic sheet, which includes a sheet-shaped elastic carrier sheet 5 and a piezoelectric ceramic layer laminated on the elastic carrier sheet 5.

[0027] One end of the elastic carrier sheet 5 is fixedly connected to the bracket 1.

[0028] The button 2 is releasably and resetably connected to the elastic carrier sheet 5 through a limit release mechanism.

[0029] The limit release mechanism is a mechanism that disconnects the connection relationship after moving to a limited position and reconnects after resetting.

[0030] The limiting and releasing mechanism includes two magnetic components, at least one of which is a permanent magnet; in the limiting and releasing mechanism, the two magnetic components have a connection relationship that can be disconnected and reconnected.

[0031] The first magnetic component 4 is connected to the button 2, and the second magnetic component 7 is fixedly connected to the elastic carrier sheet 5, so that the second magnetic component 7 also functions as a counterweight for the elastic carrier sheet 5.

[0032] The stroke of the first magnetic component 4 connected to the button 2 is greater than the limiting stroke of the second magnetic component 7 restricted by the elastic carrier sheet 5.

[0033] When the button 2 is pressed to the bottom, the distance between the two magnetic components is less than the distance at which the button 2 is reset by magnetic attraction again after the force on the button 2 is eliminated.

[0034] The bracket 1 and the elastic carrier sheet 5 are arranged in the switch housing.

[0035] By using a piezoelectric ceramic sheet and only two magnetic components, a limiting and releasing mechanism with limiting and automatic reset functions is completed.

[0036] A simple structure is adopted to complete the design of the "piezoelectric magnetic adsorption self-powered power supply", which has the advantages of simple structure, low cost, and reliable performance.

[0037] The elastic carrier sheet 5 of the piezoelectric ceramic sheet is made of an elastic steel sheet.

[0038] Through the above design, although elastic vibration is generated, no additional elastic components are added. Only a piezoelectric ceramic sheet with an elastic carrier sheet 5 made of an elastic steel sheet is used to complete the functions of the piezoelectric material sheet and the elastic component at the same time.

[0039] The simplicity of this patent not only reduces the cost, but also improves the reliability during use and greatly extends or ensures the service life because of the reduction of components.

[0040] During the working process, when the button 2 is pressed, since the stroke of the magnetic component connected to the button 2 is greater than the limiting stroke of the second magnetic component 7 restricted by the elastic carrier sheet 5, the two magnetic components are separated after the button 2 reaches a certain amplitude. The way the elastic carrier sheet 5 restricts the stroke of the second magnetic component 7 can be restricted by increasing the elastic force.

[0041] During the stroke of the first magnetic component 4 connected to the button 2, there is a position where the magnetic force between the two magnetic components is less than the elastic force of the elastic carrier sheet 5.

[0042] When the button 2 is pressed, as the two magnetic components move together with the button 2, the elastic force of the elastic carrier sheet 5 increases accordingly. When the elastic force increases to a level greater than the magnetic force, the stroke of the second magnetic component 7 is restricted and it no longer follows the movement, and then the two magnetic components separate.

[0043] After separation, due to the rapid attenuation of the magnetic force, the elastic carrier sheet 5 rebounds quickly. And since the second magnetic component 7 serves as a counterweight, continuous vibrations or oscillations with a relatively large amplitude are generated, generating a continuous current with a relatively high voltage.

[0044] In the above design, without adding a limiting component 6, only through the original components and through mechanical changes, the limiting function is completed.

[0045] Also, due to the existence of the magnetic force between the two magnetic components, after the button 2 is released, it is easy to automatically re - engage and complete the reset.

[0046] A buffer layer is provided between the two magnetic components and is fixed on one of the magnetic components, which is used to reduce or avoid the collision damage when the magnetic components are reset, and has a noise - elimination effect to reduce the possible noise during operation.

[0047] The limiting and releasing mechanism may further include a limiting component 6 for restricting the movement amplitude of the elastic carrier sheet 5, and the limiting component 6 is arranged at at least one end of the elastic carrier sheet 5;

[0048] The limiting component 6 is a component that hinders at least one end of the elastic carrier sheet 5 from moving towards the first magnetic component 4;

[0049] The limiting component 6 is slidably connected to the elastic carrier sheet 5;

[0050] The second magnetic component 7 is arranged at a position between one end close to the limiting component 6 and the other end of the elastic carrier sheet 5.

[0051] When the first magnetic component 4 pulls, the limiting component 6 hinders at least one end of the elastic carrier sheet 5 from moving towards the first magnetic component 4, and then the second magnetic component 7 causes the middle part of the elastic carrier sheet 5 to bend towards the first magnetic component 4.

[0052] The elastic carrier sheet 5 is an elastic carrier sheet whose elastic force is greater than the magnetic force between the first magnetic component 4 and the second magnetic component 7 before it slips out of the limiting component 6.

[0053] Before the elastic carrier sheet 5 slips out of the limiting component 6, the restoring force generated by the elastic force of the elastic carrier sheet 5 is greater than the magnetic force, and then it rebounds.

[0054] The design of this limiting component 6 features a simple structure. At the same time, since the bending part is located in the middle part rather than setting the position with the largest bending amplitude at one end, the deformation over long-term use is lower, the service life is longer, the metal fatigue resistance life is longer, and the generated electric energy is more stable.

[0055] Furthermore, the piezoelectric material sheet is at least two layers of piezoelectric ceramic sheets stacked up and down.

[0056] By adopting the method of stacking at least two layers of piezoelectric ceramic sheets to generate the piezoelectric material sheet, although it will appropriately reduce the duration of oscillatory (vibratory) deformation, it can enhance the current output or voltage output within a short time.

[0057] For a wireless remote control circuit with short communication time requirements, it has a better usage effect.

[0058] One end of the elastic carrier sheet 5 is fixedly connected to the bracket 1, and the second magnetic component 7 is arranged at the end far from the fixation and at a position greater than two-thirds of the overall length. It can better assist and strengthen the vibration.

[0059] The weight of the second magnetic component 7 uses a magnetic component with a mass greater than 3g and less than 20g. Through experiments, the counterweight of this weight is easy to start vibrating and will not cause the equipment to be easily damaged due to being too heavy.

[0060] Because the second magnetic component 7 is only supported by the elastic carrier sheet 5 during operation, it is relatively fragile during operation or transportation. In this patent, restricting it within more than 3g and less than 20g can not only ensure the vibration amplitude and frequency but also ensure the reliability of the system.

[0061] Furthermore, the second magnetic component 7 uses a soft magnetic component, and the first magnetic component 4 uses a permanent magnet.

[0062] Avoid unnecessary magnetic field changes caused by the second magnetic component 7 during oscillation, which hinders the oscillation action.

[0063] One end of the elastic carrier sheet 5 is fixedly connected to the bracket 1. The elastic carrier sheet 5 is an elastic carrier sheet made of soft magnetic material, and the second magnetic component 7 and the elastic carrier sheet 5 are an integral body.

[0064] Furthermore, one end of the elastic carrier sheet 5 is fixedly connected to the bracket 1, and the other end of the elastic carrier sheet 5 is bent and folded to form the second magnetic component 7.

[0065] It avoids the fixing process of the second magnetic component 7 and the elastic carrier sheet 5, and makes their combination more firm. It further reduces costs and enhances reliability.

[0066] The button 2 can be a lever-type button 2, a press-type button 2, etc. As long as the button 2 is movable, it can be used.

[0067] The rectifying, voltage-stabilizing, and energy-storing circuits, as well as the wireless, infrared, or other signal transmitting circuits that are matched with it, are not described in detail in this patent.

[0068] Refer to Figure 1 、 2 As shown in FIGS. 3 and 4, the piezoelectric magnetic adsorption self-powered power supply includes a bracket 1, and also includes a movable button 2 assembled on the bracket 1; it also includes a piezoelectric material sheet; the piezoelectric material sheet includes a sheet-shaped elastic carrier sheet 5 and a piezoelectric material layer 3 that generates electric energy through deformation; the elastic carrier sheet 5 is directly or indirectly installed on the bracket 1; the button 2 is directly or indirectly disconnectably connected to the elastic carrier sheet 5 through a limit release mechanism; the limit release mechanism is a mechanism that disconnects the connection relationship between the button 2 and the elastic carrier sheet 5 after moving to a limited position and reconnects after resetting.

[0069] Through the above design, at the initial stage of pressing the button 2, since the elastic carrier sheet 5 is not driven to move to the limited position, the button 2 drives the elastic carrier sheet 5 to generate deformation.

[0070] After reaching the limited position, the limit release mechanism disconnects the connection relationship, completing the release of the elastic carrier sheet 5. After the elastic carrier sheet 5 is released, it rebounds due to elasticity, thereby driving the piezoelectric material layer 3 to generate oscillatory (vibratory) deformation and generate electric energy. It has the advantages of small volume, simple structure, low cost, long power generation time, stable current, etc.

[0071] The piezoelectric material sheet can be a sheet-shaped piezoelectric material sheet;

[0072] The sheet-shaped piezoelectric material sheet includes an elastic carrier sheet 5 and a piezoelectric material layer 3 attached to the elastic carrier sheet 5.

[0073] For the necessary electrode settings in the structure of the piezoelectric material sheet, no specific description is made.

[0074] The piezoelectric material sheet includes a sheet-shaped elastic carrier sheet 5 and a piezoelectric material layer 3 that generates electric energy through deformation. The piezoelectric material layer 3 can be at least one of a piezoelectric ceramic layer, polarized polyvinylidene fluoride, polybenzyl glutamate, cyanoethyl cellulose, poly-L-lactic acid film, electrospinning (PLLA nanofibers or thin films), and PVDF-TrFE.

[0075] Polarized polyvinylidene fluoride, poly(benzyl L-glutamate), cyanoethyl cellulose, poly(L-lactic acid) film, electrospun (PLLA nanofibers or films), piezoelectric polymers such as PVDF-TrFE can generate a smaller piezoelectric magnetic self-powered power source, which can be used for some energy capture in life.

[0076] For a manual wireless remote control switch, the piezoelectric material sheet is preferably a piezoelectric ceramic sheet with a piezoelectric ceramic layer attached to an elastic carrier sheet 5.

[0077] The manual wireless remote control switch should be easy for users to find and have easy recognition, so its volume is relatively large. For a device of this volume, the piezoelectric magnetic self-powered power source does not need to be too small.

[0078] Moreover, as long as the piezoelectric magnetic self-powered power source generates a current for less than 1 second (which can be stored and used to emit a signal in a shorter time), it can be sufficient to complete the remote control operation. In order to reduce the requirements for the circuit part, reduce production costs and increase reliability. A reliable current output is preferably greater than 1 millisecond.

[0079] The structure using a piezoelectric ceramic sheet has the characteristics of low cost, stable material supply, and easy mass production. When used in the structure of this patent, for the manual wireless remote control switch, it can provide sufficient accommodation space for the piezoelectric ceramic sheet, and the piezoelectric ceramic sheet can generate an appropriate current of an appropriate size.

[0080] Furthermore, the piezoelectric material sheet is at least two layers of piezoelectric ceramic sheets stacked up and down.

[0081] By adopting the method of stacking at least two layers of piezoelectric ceramic sheets to form the piezoelectric material sheet, although the duration of oscillatory (vibrational) deformation will be appropriately reduced, the current output or voltage output in a short time can be enhanced.

[0082] It has better use effects for wireless remote control circuits with short communication time requirements.

[0083] The elastic carrier sheet 5 of the piezoelectric ceramic sheet is made of an elastic steel sheet.

[0084] In this patent, for the piezoelectric ceramic sheet, instead of using the traditional copper sheet, an elastic steel sheet is used. Although the electrical conductivity is reduced, elasticity is obtained, which is easy to generate a more persistent and larger amplitude vibration and a more persistent and stable current output.

[0085] Further preferably, a copper layer is provided above the elastic steel sheet, and a piezoelectric ceramic layer is formed above the copper layer.

[0086] The bracket 1 is arranged in a cavity, and the elastic carrier sheet 5 is arranged in the cavity; one end of the elastic carrier sheet 5 is fixedly connected to the bracket 1, avoiding being affected by the installation environment or external components.

[0087] The limiting and releasing mechanism includes two magnetic components, at least one of which is a permanent magnet; in the limiting and releasing mechanism, the two magnetic components have a connectable and reconnectable connection relationship;

[0088] The first magnetic component 4 is linked with the key 2, and the second magnetic component 7 is arranged on the elastic carrier sheet 5;

[0089] The limiting and releasing mechanism may further include a limiting component 6 for limiting the movement amplitude of the elastic carrier sheet 5.

[0090] When pressing the key 2, it drives the first magnetic component 4 to move, and then drives the second magnetic component 7 to move, and then drives the elastic carrier sheet 5 to move. When the movement amplitude of the elastic carrier sheet 5 exceeds the amplitude limited by the limiting component 6, the first magnetic component 4 is separated from the second magnetic component 7, and the elastic carrier sheet 5 rebounds to complete power generation.

[0091] The limiting component limits the movement amplitude of the elastic carrier sheet, avoiding the mechanical design in which the elastic carrier sheet separates the first magnetic component and the second magnetic component through its own elastic force, effectively reducing the problem of mechanical property change of the elastic "overwork" of the elastic carrier sheet. It ensures the performance stability during long-term use and greatly improves the service life.

[0092] The allowable stroke of the first magnetic component 4 linked with the key 2 is greater than the limiting stroke of the second magnetic component 7 restricted by the elastic carrier sheet 5.

[0093] Since the stroke of the first magnetic component 4 linked with the key 2 is greater than the limiting stroke of the second magnetic component 7 restricted by the elastic carrier sheet 5, the two magnetic components are separated after the key 2 is pressed to a certain amplitude. The work of the limiting and releasing mechanism is completed.

[0094] The way for the elastic carrier sheet 5 to limit the stroke of the second magnetic component 7 is to limit it by increasing the elastic force.

[0095] During the stroke of the first magnetic component 4 connected to the key 2, there is a position where the magnetic force between the two magnetic components is less than the elastic force of the elastic carrier sheet 5.

[0096] During the process of pressing the key 2, the elastic force of the elastic carrier sheet 5 increases and exceeds the magnetic force, thereby restricting the stroke of the second magnetic component 7. Therefore, after the key 2 is pressed to a certain amplitude, the two magnetic components are separated.

[0097] During the working process, when pressing the key 2, since the stroke of the first magnetic component 4 connected to the key 2 is greater than the limiting stroke of the second magnetic component 7 restricted by the increase in the elastic force of the elastic carrier sheet 5, the two magnetic components are separated after the key 2 is pressed to a certain amplitude.

[0098] When the button 2 is pressed, as the two magnetic components move together with the button 2, the elastic force of the elastic carrier sheet 5 increases accordingly. When the elastic force increases to a level greater than the magnetic force, the stroke of the second magnetic component 7 is restricted and it no longer follows the movement, and then the two magnetic components are separated.

[0099] After separation, due to the rapid attenuation of the magnetic force, the elastic carrier sheet 5 rebounds quickly. And because the second magnetic component 7 serves as a counterweight, continuous vibrations or oscillations with a relatively large amplitude are generated, generating a continuous current with a relatively high voltage.

[0100] Also, due to the existence of the magnetic force between the two magnetic components, after the button 2 is released, they are likely to automatically attract each other again to complete the reset.

[0101] The above design adopts the simplest structure to complete the design of the "piezoelectric magnetic adsorption self-generating power supply", which has the advantages of simple structure, low cost, reliable performance, etc.

[0102] The weight of the second magnetic component 7 uses a magnetic component with a mass greater than 2 g and less than 15 g. Through experiments, a counterweight of this weight can not only easily start vibration but also will not cause the equipment to be easily damaged due to excessive weight.

[0103] Because the second magnetic component 7 is only supported by the elastic carrier sheet 5 during operation, it is relatively fragile during operation or transportation. In this patent, it is limited to be greater than 2 g and less than 15 g, which not only ensures the vibration amplitude and frequency but also ensures the reliability of the system.

[0104] Furthermore, the second magnetic component 7 uses a soft magnetic component, and the first magnetic component 4 uses a permanent magnet.

[0105] Avoid unnecessary magnetic field changes caused by the second magnetic component 7 during oscillation, which hinders the oscillation action.

[0106] A preferred solution is:

[0107] The first magnetic component 4 is fixedly connected to the button 2, and the second magnetic component 7 is fixedly connected to the elastic carrier sheet 5, using the second magnetic component 7 as a counterweight to enhance the vibration (oscillation) of the elastic carrier sheet 5.

[0108] A buffer layer is provided between the two magnetic components.

[0109] It is used to reduce or avoid the collision damage during the reset of the magnetic components and has a noise elimination effect, reducing the possible noise during operation.

[0110] Further preferably, the buffer layer uses a rubber sleeve, which is sleeved on one of the magnetic components. Specific Embodiment 1:

[0112] The limiting and releasing mechanism may further include a limiting member 6 for restricting the movement amplitude of the elastic carrier sheet 5, and the limiting member 6 is arranged on the movement track of the elastic carrier sheet 5.

[0113] When the elastic carrier sheet 5 moves to the position of the limiting member 6, it is blocked, and then the two magnetic members are separated. Specific Embodiment 2:

[0115] The limiting and releasing mechanism further includes a limiting member 6 for restricting the movement amplitude of the elastic carrier sheet 5, and the limiting member 6 is arranged at at least one end of the elastic carrier sheet 5;

[0116] The limiting member 6 is a limiting member 6 that hinders at least one end of the elastic carrier sheet 5 from moving towards the first magnetic member 4;

[0117] The limiting member 6 is slidably connected to the elastic carrier sheet 5;

[0118] The second magnetic member 7 is arranged at a position between one end of the elastic carrier sheet 5 close to the limiting member 6 and the other end.

[0119] When the first magnetic member 4 pulls, the limiting member 6 hinders at least one end of the elastic carrier sheet 5 from moving towards the first magnetic member 4, and then the second magnetic member 7 causes the middle part of the elastic carrier sheet 5 to bend towards the first magnetic member 4.

[0120] The elastic carrier sheet 5 is an elastic carrier sheet 5 whose elastic force generated before slipping off from the limiting member 6 is greater than the magnetic force between the first magnetic member 4 and the second magnetic member 7.

[0121] Before the elastic carrier sheet 5 slips off from the limiting member 6, the restoring force generated by the elastic force of the elastic carrier sheet 5 is greater than the magnetic force, and then it rebounds.

[0122] This design of the limiting member 6 has the characteristics of simple structure. At the same time, because the bending part is at a position near the middle, rather than setting the position with the largest bending amplitude at one end. The deformation during long-term use is lower, the service life is longer, the metal fatigue resistance life is longer, and the generated electric energy is more stable.

[0123] The limiting member 6 may further be provided with a limiting and blocking structure, and a structure matching the limiting and blocking structure is arranged on the elastic carrier sheet 5.

[0124] When the elastic carrier sheet 5 moves to the position of the limiting member 6, it is blocked, and then the two magnetic members are separated.

[0125] The position-limiting and blocking structure is provided so that the elastic carrier sheet 5 can rebound under the condition of generating lower elasticity.

[0126] The deformation is lower after long-term use, the service life is longer, the metal fatigue life is longer, and the generated electricity is more stable.

[0127] The limiting blocking structure of the limiting component 6 can adopt a stopper, and the elastic carrier sheet 5 is provided with a strip-shaped hole;

[0128] The blocking head is inserted into the strip-shaped hole, and the strip-shaped hole is used as a structure matched with the position limiting blocking structure.

[0129] The edge of a strip-shaped hole is used as a trigger amplitude for limiting. When the stopper abuts against the edge of the strip-shaped hole, the magnetic coupling between the first magnetic component 4 and the second magnetic component 7 is disconnected.

[0130] The use of bar-shaped holes can effectively limit left and right shaking while allowing forward and backward sliding, making the device more solid and running more stable. Specific embodiment 3:

[0132] Furthermore, one end of the elastic carrier sheet 5 is fixedly connected to the bracket 1 , the elastic carrier sheet 5 is an elastic carrier sheet 5 made of soft magnetic material, and the second magnetic component 7 is integral with the elastic carrier sheet 5 .

[0133] The fixing process of the second magnetic component 7 and the elastic carrier sheet 5 is avoided, and the combination is more firmly made, thereby further reducing the cost and enhancing the reliability.

[0134] Furthermore, one end of the elastic carrier sheet 5 is fixedly connected to the bracket 1 , and the other end of the elastic carrier sheet 5 is bent and folded to form the second magnetic component 7 .

[0135] It not only ensures the counterweight performance, but also realizes integration. Specific embodiment 4:

[0137] At least one end of the elastic carrier sheet 5 is connected to an elastic component, and then connected to the bracket 1 through the elastic component;

[0138] The limit release mechanism comprises an elastic component, a first magnetic component 4, and a second magnetic component 7;

[0139] The second magnetic component 7 is arranged between the two ends of the elastic carrier sheet 5;

[0140] The stroke of the first magnetic component 4 connected to the button 2 is greater than the limited stroke of the second magnetic component 7 which is limited by the increased elastic force of the elastic component.

[0141] The limiting travel mode of the elastic carrier sheet 5 for the second magnetic component 7 is restricted by the increased elastic force of the elastic component.

[0142] The travel of the first magnetic component 4 connected to the button 2 is greater than the limiting travel of the second magnetic component 7 restricted by the elastic component. After the button 2 reaches a certain amplitude, the two magnetic components are separated. The work of the limiting release mechanism is completed, generating electric energy.

[0143] After the second magnetic component 7 is released, it will generate vibration and can generate more electric energy.

[0144] The design in Specific Embodiment 4 is more concise and reliable. There is no relative movement between the two ends of the elastic carrier sheet 5 and the bracket 1, and there can be no friction and collision. Not only is the production cost lower, but it also has a longer service life. Specific Embodiment 5:

[0146] The two ends of the elastic carrier sheet 5 are respectively arranged on the bracket 1; an elastic bend 8 is arranged between the two ends of the elastic carrier sheet 5;

[0147] The limiting release mechanism includes an elastic bend 8, a first magnetic component 4, and a second magnetic component 7;

[0148] The second magnetic component 7 is arranged at a position between the two ends of the elastic carrier sheet 5;

[0149] The travel of the first magnetic component 4 connected to the button 2 is greater than the limiting travel of the second magnetic component 7 restricted by the increased elastic force of the elastic bend 8.

[0150] The limiting travel mode of the elastic carrier sheet 5 for the second magnetic component 7 is restricted by the increased elastic force of the elastic bend 8.

[0151] The travel of the first magnetic component 4 connected to the button 2 is greater than the limiting travel of the second magnetic component 7 restricted by the elastic carrier sheet 5. After the button 2 reaches a certain amplitude, the two magnetic components are separated. The work of the limiting release mechanism is completed, generating electric energy.

[0152] After the second magnetic component 7 is released, it will generate vibration and can generate more electric energy.

[0153] In the design of Specific Embodiment 4, the elastic bend 8 is formed on the elastic carrier sheet 5, with lower cost, more concise structure, and more reliable use. There is no relative movement between the two ends of the elastic carrier sheet 5 and the bracket 1, and there can be no friction and collision. Not only is the production cost lower, but it also has a longer service life.
