Description

Technical Field

[0001] The utility model relates to the technical field of buttons, in particular to a self-generating button and a remote control and an intelligent toilet cover having the same. Background Art

[0002] In the prior art, self-generating buttons usually have built-in piezoelectric components. When the button presses the spring, the spring transmits the pressure to the piezoelectric component, causing the piezoelectric component to deform, and a potential difference is generated at both ends to generate electrical energy. In this process, after the pressure on the button is removed, the button quickly resets under the action of the spring, and no longer applies pressure to the piezoelectric component. The piezoelectric component is no longer deformed to generate electrical energy under force, so the deformation power generation time is short and the power generation capacity is weak.

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] refer to Figure 1 Some embodiments of the utility model provide a self-generating button 1000, which triggers an internal switch when pressed, and is used to send a control signal to a target device. At the same time, the internal self-generating mechanism can generate electrical energy using the pressing pressure. The electrical energy can be stored in the internal circuit board of the button, or directly used for power supply.

[0031] For example, the electric energy generated by the self-generation is stored in the capacitor of the circuit board for standby use or directly powers the signal transmission module inside the button, so that the signal transmission module can operate without external power supply.

[0032] The self-generating button 1000 can be used as an independent control module, such as an independently set button switch, etc.; it can also be set on some control devices, such as a remote control, etc.; it can also be integrated into a specific target device as its control switch, such as the cover of a smart toilet, to control the various functional modules on the toilet.

[0033] refer to Figures 1 to 4 In some embodiments, the self-generating button 1000 includes a housing 100 and a pressing component 200. The housing 100 includes a receiving cavity 101, and the pressing component 200 can move relative to the housing 100 to press the component in the receiving cavity 101.

[0034] For example, the pressing component 200 and the housing 100 are respectively provided with engaging parts, such as buckles and slots, etc., and the pressing component 200 and the housing 100 are slidably connected through the engaging parts, and the pressing component 200 can move relative to the housing 100 to press the components in the accommodating cavity 101, and the engaging parts restrict the two from being separated. Alternatively, one side of the pressing component 200 can be rotationally connected to one side of the housing 100, and the pressing component 200 and the other side of the housing 100 are limitedly connected, and in this case, the pressing component 200 rotates relative to the housing 100 to press the components in the accommodating cavity 101.

[0035] Among them, reference Figure 3 and Figure 4 , the self-generating button 1000 also includes a piezoelectric element 300, an elastic component 400, and a circuit component 900. The piezoelectric element 300 refers to a crystalline material that deforms when subjected to pressure and generates a voltage between the two end faces, such as piezoelectric ceramics, piezoelectric single crystals, organic piezoelectric films, composite piezoelectric elements, etc. The piezoelectric element 300 and the elastic component 400 are both arranged in the accommodating cavity 101 of the housing 100. When the pressing component 200 is pressed, one end of the elastic component 400 abuts against the pressing component 200, and the other end abuts against the piezoelectric element 300. Therefore, when the pressing component 200 is subjected to a pressing force, the pressure can be transmitted to the piezoelectric element 300 by compressing the elastic component 400, so that the piezoelectric element 300 is deformed to generate electrical energy. The generated electrical energy can be directly transmitted to the power module through the circuit component 900 in the button or stored in the circuit component 900. After the pressing force is withdrawn, the pressing component 200 is reset, the elastic component 400 rebounds, the piezoelectric component 300 is no longer deformed by pressure, and stops generating electricity. During this process, the elastic component 400 rebounds quickly and no longer generates pressure on the piezoelectric component 300, resulting in a shorter deformation time of the piezoelectric component 300, and thus a shorter power generation time and weaker power generation capacity. Therefore, the self-generating button 1000 is also provided with a reset delay component 500, which can act on the reset process of the pressing component 200. Specifically, through the reset delay component 500, a force is applied to the pressing component 200 in the direction opposite to the reset direction of the pressing component 200, thereby reducing the reset speed of the pressing component 200, thereby prolonging the process of the elastic component 400 rebounding and recovering, so that it continues to generate pressure on the piezoelectric component 300 during the extended recovery process, so that it continues to maintain deformation and power generation.

[0036] refer to Figure 3 and Figure 4In some embodiments of the present invention, the reset delay component 500 includes a first delay component and a second delay component, the first delay component is arranged on a side of the pressing component 200 close to the accommodating cavity 101, and the second delay component is arranged in the accommodating cavity 101, wherein, during the pressing process of the pressing component 200, the first delay component and the second delay component approach each other, and during the resetting process of the pressing component 200, the first delay component and the second delay component move away from each other, and the second delay component applies a force to the first delay component in a direction opposite to the direction in which the first delay component moves away, that is, a magnetic attraction force that hinders the resetting of the pressing component 200 is applied, thereby reducing its resetting speed and delaying the resetting time.

[0037] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the first delay member may be a magnet 502, and the second delay member may be a closed coil 501. Alternatively, the first delay member may be a closed coil 501, and the second delay member may be a magnet 502. Below, taking the first delay member as a magnet 502 and the second delay member as a closed coil 501 as an example, the working process and principle of this embodiment are further described:

[0038] The magnet 502 is fixedly mounted on the pressing component 200 through the fixing hole 2023, and the closed coil 501 is arranged on the circuit component 900. Specifically, a positioning column 503 is arranged on the circuit component 900, and the closed coil 501 is arranged around the positioning column 503. The positioning column 503 is provided with an opening for the magnet 502 to penetrate and disengage. When the pressing component 200 is pressed and the elastic component 400 is compressed to make the piezoelectric element 300 deform and generate electricity, the magnet 502 penetrates into the opening of the positioning column 503. When the pressing force on the pressing component 200 is removed, the pressing component 200 is affected by the recovery action of the elastic component 400 and is pushed to move in the reset direction of the pressing component 200. At this time, the pressing component 200 drives the magnet 502 to move to gradually disengage from the positioning column 503. At this time, during the relative movement between the magnet 502 and the closed coil 501, it is equivalent to the closed coil 501 cutting the magnet 502. The magnetic lines of force generate an induced current, and the induced current also generates a magnetic flux. According to Lenz's law, the magnetic flux generated by the induced current in the loop always hinders the change of the original magnetic flux. Therefore, when the magnet 502 moves from the coil to the disengaged state, the closed coil 501 will apply a force to the magnet 502 in the opposite direction of the reset direction, hindering the movement of the magnet 502 and the pressing component 200, reducing the reset speed of the pressing component 200, delaying the reset time, and allowing the elastic component 400 to continue to generate pressure on the piezoelectric component 300, thereby extending the power generation time of the piezoelectric ceramic and increasing the power generation.

[0039] Furthermore, an air hole connecting the internal space of the positioning column 503 and the outside is also provided at one end of the positioning column 503 away from the magnet 502. When the pressing component 200 is pressed, the magnet 502 is inserted into the opening of the positioning column 503. At this time, the volume of the open cavity in the positioning column 503 is compressed, and the gas therein is discharged through the air hole. When the pressing component 200 is reset, the magnet 502 moves in the direction of separating from the positioning column 503. At this time, the volume of the internal cavity of the positioning column 503 suddenly increases, and the speed of the external gas entering the internal space of the positioning column 503 through the air hole is limited, and it is impossible to balance the air pressure inside and outside the positioning column 503 in real time, so that the air pressure in the positioning column 503 is lower than the external atmospheric pressure. The end of the magnet 502 away from the positioning column 503 is affected by the atmospheric pressure and cannot be quickly withdrawn, thereby reducing the reset speed of the pressing component 200 and delaying the reset time.

[0040] Therefore, the resetting process of the pressing component 200 is not only affected by the interaction force between the magnet 502 and the closed coil 501, but also can utilize the atmospheric pressure difference to exert multiple forces that hinder the resetting process of the pressing component 200.

[0041] In some embodiments of the present invention, the first delay member and the second delay member may both be magnets (not shown), and the opposite ends of the two magnets have opposite magnetic properties.

[0042] It is understandable that when the pressing component 200 is not pressed, the distance between the first delay part and the second delay part is relatively large. At this time, there is no magnetic attraction between the two or the magnetic attraction is extremely small. When the pressing component 200 is pressed, the elastic component 400 is compressed to bring the first delay part and the second delay part closer to each other. At this time, a magnetic attraction is generated between the two magnets, but the magnetic attraction is still smaller than the elastic force when the elastic component 400 is reset. Therefore, the elastic component 400 drives the pressing component 200 to reset. At this time, the magnetic attraction between the two magnets can cause the pressing component 200 to be subjected to a force in the opposite direction to the reset direction, thereby achieving a delay effect.

[0043] Furthermore, one of the first delay member and the second delay member is a plunger, and the other is a sleeve. When the pressing assembly 200 is pressed, the plunger can be inserted into the sleeve, and when the pressing assembly 200 is reset, the plunger is separated from the sleeve. Among them, an air hole connecting the internal space of the sleeve and the outside is provided at one end of the sleeve away from the plunger. When the pressing assembly 200 is pressed, the plunger is inserted into the sleeve, and the cavity in the sleeve is compressed. When the pressing assembly 200 is reset, the plunger is separated from the sleeve, so that the volume of the cavity in the sleeve increases. The speed of the gas entering the sleeve cavity through the air hole is limited, and it is impossible to balance the air pressure inside and outside the sleeve in real time, so that the air pressure in the sleeve is lower than the external atmospheric pressure. The end of the plunger away from the sleeve is affected by the atmospheric pressure and cannot be quickly withdrawn, thereby reducing the reset speed of the pressing assembly 200 and delaying the reset time.

[0044] In some embodiments of the present invention, one of the first delay member and the second delay member is a magnet, and the other is made of metal material.

[0045] It can be understood that when the pressing component 200 is not pressed, the distance between the first delay part and the second delay part is relatively large. At this time, there is no magnetic attraction between the two or the magnetic attraction is extremely small. When the pressing component 200 is pressed, the elastic component 400 is compressed to bring the first delay part and the second delay part closer to each other. At this time, a magnetic attraction is generated between the two, but the magnetic attraction is still smaller than the elastic force when the elastic component 400 is reset. Therefore, the elastic component 400 drives the pressing component 200 to reset. At this time, the magnetic attraction between the first delay part and the second delay part can cause the pressing component 200 to be subjected to a force in the opposite direction to the reset direction, thereby achieving a delay effect.

[0046] Furthermore, one of the first delay member and the second delay member is a plunger, and the other is a sleeve. When the pressing assembly 200 is pressed, the plunger can be inserted into the sleeve, and when the pressing assembly 200 is reset, the plunger is separated from the sleeve. Among them, an air hole connecting the internal space of the sleeve and the outside is provided at one end of the sleeve away from the plunger. When the pressing assembly 200 is pressed, the plunger is inserted into the sleeve, and the cavity in the sleeve is compressed. When the pressing assembly 200 is reset, the plunger is separated from the sleeve, so that the volume of the cavity in the sleeve increases. The speed of the gas entering the sleeve cavity through the air hole is limited, and it is impossible to balance the air pressure inside and outside the sleeve in real time, so that the air pressure in the sleeve is lower than the external atmospheric pressure. The end of the plunger away from the sleeve is affected by the atmospheric pressure and cannot be quickly withdrawn, thereby reducing the reset speed of the pressing assembly 200 and delaying the reset time.

[0047] In some embodiments of the present invention, one of the first delay member and the second delay member can be a plunger, and the other can be a sleeve, wherein a damping material (such as silicone oil, etc.) (not shown) is provided on the outer wall of the plunger and / or the inner wall of the sleeve. When the pressing component 200 is pressed, the plunger can penetrate into the sleeve. When the pressing component 200 is reset, the plunger and the positioning column 503 are separated from each other, and the damping material is in the gap between the two, thereby hindering the relative movement between the two, reducing the separation speed, and delaying the reset time.

[0048] refer to Figure 3 , Figure 4 and Figure 7 In some embodiments of the utility model, the circuit component 900 can be a circuit board, which is arranged in the accommodating cavity 101 of the shell 100 and is limited and fixed by a positioning mechanism in the shell 100. A micro switch 901 is also provided on the circuit board 900. When the pressing component 200 is pressed, the target function control can be achieved by pressing the micro switch 901, and self-generation of the button can be achieved.

[0049] refer to Figure 3 , Figure 4 and Figure 6 In some embodiments of the utility model, the elastic component 400 includes a first elastic member, a counterweight 402, a second elastic member and a pot piece 405 that are abutted in sequence. In the axial direction of the first elastic member, one end of the first elastic member that faces away from the counterweight 402 abuts against the pressing component 200, and one end of the pot piece 405 that faces away from the second elastic member abuts against the piezoelectric member 300. Since the pot piece 405 will deform instantly when the force reaches the limit, at this time, the counterweight 402 can vibrate repeatedly between the first elastic member and the second elastic member, thereby increasing the deformation amount and deformation frequency of the piezoelectric ceramic within a certain time range, thereby increasing the power generation and power generation efficiency. The process and principle of this embodiment are further explained below:

[0050] When the self-generating button 1000 is pressed, the pressing component 200 pushes against the first elastic member to compress it, and at the same time, the force is transmitted to the second elastic member through the counterweight block 402 to compress and deform it. During this process, the counterweight block 402 is simultaneously subjected to the elastic forces of the first elastic member and the second elastic member, and moves toward the pot piece 405 as the first elastic member and the second elastic member are compressed. The pot piece 405 is subjected to the elastic force of the second elastic member and is squeezed toward the piezoelectric member 300 to deform and generate electricity. Due to the characteristics of the pot piece 405 itself, when the force on the pot piece 405 reaches the limit, it will instantly deform, causing the side that abuts the second elastic member to quickly recess toward the piezoelectric member 300. At this time, the deformation path of the second elastic member increases instantaneously, and the second elastic member is partially reset. As a result, the elastic force of the second elastic member on the pot piece 405 and the counterweight block 402 is instantly reduced, which also causes the pressure of the pot piece 405 on the piezoelectric member 300 to decrease, so that the part of the piezoelectric member 300 that has achieved rapid deformation is restored to a certain extent. At this time, the counterweight block 402 moves rapidly toward the direction of the second elastic member under the action of its own gravity and the elastic force of the first elastic member, thereby pushing the second elastic member to increase the elastic force on the pot piece 405, so that the pressure of the pot piece 405 on the piezoelectric member 300 increases again, causing the piezoelectric member 300 to deform and generate electricity again. When the counterweight 402 moves to the extreme position in the direction of the second elastic member, the counterweight 402 is simultaneously subjected to the tensile force of the first elastic member and the elastic force of the second elastic member, moves in the direction of the first elastic member, compresses the first elastic member and resets the second elastic member and gradually stretches it, at which time the force on the pot piece 405 and the piezoelectric member 300 is reduced, and the piezoelectric member 300 is partially restored again. When the counterweight 402 moves to the extreme position in the first elastic direction, the counterweight 402 is simultaneously subjected to the tensile force of the second elastic member and the elastic force of the first elastic member, at which time the counterweight 402 moves again in the direction of the second elastic member and applies pressure to the pot piece 405, increasing the pressure on the piezoelectric member 300, causing the piezoelectric member 300 to deform and generate electricity again. The above process is repeated until the pressure on the pot piece 405 is less than its deformation limit pressure no matter which of the two directions the counterweight 402 moves in. The pot piece 405 is reset and no longer undergoes instantaneous concave deformation before the next pressing action. At this time, the pot piece 405 is reset so that the side close to the second elastic member is instantly convex, causing the deformation displacement distance of the second elastic member to be instantly compressed. The counterweight 402 is suddenly increased by the elastic force from the second elastic member and moves toward the first elastic member, thereby causing the elastic component 400 to cycle the above-mentioned repetitive movement process again until the force applied by the elastic component 400 to the piezoelectric element 300 is no longer sufficient to cause it to deform, and the power generation process ends.It should be noted that during the period from the first deformation of the pot piece 405 to the time when the instantaneous concave deformation no longer occurs, there is also a stage in which when the counterweight block 402 moves toward the first elastic member so that the pot piece 405 is subjected to an elastic force less than the deformation limit, and when the counterweight block 402 moves toward the second elastic member so that the pot piece 405 is subjected to an elastic force greater than the deformation limit, the pot piece 405 is constantly deforming and recovering, and each deformation and recovery repeats the above-mentioned deformation and movement process of the elastic component 400, thereby significantly increasing the deformation amount and frequency of the piezoelectric component 300, which is beneficial to improving the power generation time and power generation of the piezoelectric component 300.

[0051] refer to Figure 4 and Figure 6 In some embodiments of the utility model, the counterweight 402 is provided with positioning portions 4021 at both ends for abutting the first elastic member and the second elastic member, and the positioning portion 4021 is a groove recessed along the axial direction of the counterweight 402. When the two ends of the counterweight 402 abut against the first elastic member and the second elastic member respectively, one end of the first elastic member and the second elastic member for abutting against the counterweight 402 is arranged in an annular groove. Thus, when the two elastic members and the counterweight 402 vibrate repeatedly due to the deformation of the pot piece 405, the counterweight 402 and the elastic member can be prevented from being separated, thereby achieving stable abutment. Among them, the groove can be a circular groove or an annular groove (such as Figure 6 ), as long as it can prevent the counterweight block 402 and the elastic member from detaching and achieve stable abutment.

[0052] It is understandable that the positioning portion 4021 can also be a protruding block protruding along the axial direction of the counterweight block 402. The protruding blocks at both ends of the counterweight block 402 penetrate into the first elastic member and the second elastic member along the axial direction respectively, which can also prevent the counterweight block 402 from detaching from the elastic member.

[0053] refer to Figure 3 and Figure 4 In some embodiments of the utility model, the first elastic member is a first spring 401, and the second elastic member includes a second spring 403 and a pressing block 404. One end of the second spring 403 abuts against the counterweight block 402, and the other end abuts against the pressing block 404. The side of the pressing block 404 close to the second spring 403 is also provided with a positioning portion abutting against the second spring 403. The side of the pressing block 404 facing away from the second spring 403 abuts against the pot piece 405 to push the pot piece 405.

[0054] Specifically, a protrusion is provided on the surface of the pressing block 404 that abuts against the pot piece 405. The cross-sectional area of ​​the protrusion in the direction perpendicular to the axis of the second spring 403 is smaller than the cross-sectional area of ​​the pressing block 404. As a result, the force of the pressing block 404 on the pot piece 405 is more concentrated, making it easier to deform the pot piece 405.

[0055] It can be understood that the positioning portion can also be any one of a circular groove, an annular groove and a protruding block.

[0056] refer to Figure 3 and Figure 4 In some embodiments of the utility model, a limiting assembly is provided in the accommodating cavity 101, and the piezoelectric component 300 and the pot piece 405 are placed in the limiting assembly and the pot piece 405 and the piezoelectric component 300 are in the optimal force-bearing position to prevent the piezoelectric component 300 and the pot piece 405 from being offset during the operation of the self-generating button 1000, thereby preventing the pot piece 405 or the piezoelectric component 300 from being deformed. The limiting assembly includes a limiting frame 600 and an annular rib 103. The annular rib 103 is arranged on the bottom wall of the housing 100 and encloses a mounting groove whose shape matches the shape of the piezoelectric element 300. The piezoelectric element 300 is arranged in the mounting groove to form a radial limit. The limiting frame 600 is covered on the mounting groove to form a mounting cavity, which forms an axial limit for the piezoelectric element 300. The limiting frame 600 is provided with a through hole 601 connecting the mounting cavity and the outside world. The contour of the through hole 601 matches the pot piece 405, and the pot piece 405 abuts against the second elastic member through the through hole 601. Therefore, the second elastic member can be inserted into the through hole 601 to act on the pot piece 405, which can not only prevent the pot piece 405 from displacement, but also ensure that the second elastic member can always be perpendicular to the pot piece 405 to ensure the pressure transmission effect.

[0057] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of the utility model, the pressing component 200 includes a rocker arm 202 and a key panel 201. The key panel 201 has a large pressing area and is convenient for users to use. The side of the rocker arm 202 close to the accommodating cavity 101 abuts against the elastic component 400, and the key panel 201 is arranged on the side of the rocker arm 202 away from the elastic component 400. When the key panel 201 is pressed, the key panel 201 can push the driving rocker arm 202 to complete the control action of pressing the micro switch 901 by pressing the rocker arm 202 while driving the elastic component 400 and the piezoelectric component 300 to complete self-generation.

[0058] For details, see Figure 2 , Figure 3 , Figure 4 and Figure 5The keypad 201 and the housing 100 are connected along the axial direction of the elastic component 400 and can move relative to each other. The side of the keypad 201 close to the accommodating chamber 101 abuts against the rocker arm 202. A rotating shaft 2021 is provided at one end of the rocker arm 202. An axial hole 102 is provided on the bottom wall of the housing 100. One end of the rocker arm 202 is pivotally connected to the inside of the housing 100 through the rotating shaft 2021 and the axial hole 102. The end of the rocker arm 202 away from the rotating shaft 2021 abuts against the elastic component 400. Therefore, when the keypad 201 is pressed, the rocker arm 202 is driven to rotate around the connection between the rocker arm 202 and the housing 100, and the other end of the rocker arm 202 pushes against the elastic component 400 for compression, thereby starting the self-generating process.

[0059] It is understandable that an axial hole may be provided at one end of the rocker arm 202 , and a rotating shaft may be provided on the bottom wall of the housing 100 .

Alternatively, a second shaft hole is provided at one end of the keypad 201, and a rotating shaft is provided on the housing 100. When the keypad 201 rotates around the housing 100, the rocker arm 202 can also be driven to move.

[0061] refer to Figure 3 and Figure 4 In some embodiments of the present invention, the self-generating key 1000 further includes a pressure cover 800 and a sealing sleeve 700. The pressure cover 800 and the sealing sleeve 700 are arranged between the rocker arm 202 and the key board 201. One end of the pressure cover 800 is close to the key board 201, and the other end presses the sealing sleeve 700 toward the rocker arm 202. Thus, the piezoelectric element 300 and the like in the accommodating cavity 101 can be sealed to prevent water vapor or even water flow from directly entering the internal part of the key during use to corrode components or even damage electronic components.
