Description

Technical Field

[0001] The present invention relates to the field of nano-power generation technology, and in particular to a shaking energy generating device and method. Background Art

[0002] Triboelectric nanogenerators are a popular research direction for energy harvesting in recent years. Figure 1 As shown in the figure, the basic principle of the traditional nano friction generator is shown. The upper and lower dielectrics 1 and 2 generate static electricity on the surface during contact and friction. Figure 1 In a), when the distance between the two dielectrics changes ( Figure 1 In b), since objects tend to remain electrically neutral, static electricity on the surfaces of dielectrics 1 and 2 induces a changing current through electrodes 1a and 1b on the back of each dielectric, thereby generating energy.

[0003] However, in practical applications, triboelectric nanogenerators still face the following technical difficulties, which have prevented them from being commercialized:

[0004] 1. For the triboelectric nanogenerator mechanism based on lateral friction, most of the energy is consumed in frictional heat generation, so the power generation efficiency is low;

[0005] 2. The power output of conventional triboelectric nanogenerators per single operation is too low to meet the power consumption needs of most mobile devices;

[0006] 3. The mechanical structure of traditional friction nanogenerators requires a large external energy input. When there is only relatively slight mechanical shaking from the outside (such as a person walking), it cannot effectively drive the corresponding mechanical structure for power generation.

[0007] Therefore, it is necessary to innovate on the basis of traditional friction nanogenerator technology to overcome the above defects and make it commercially viable. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the present invention provides a shaking energy generating device and method, which does not require contact friction between the plates, can improve the power generation efficiency and single power generation, and can generate electricity under slight mechanical shaking, and can be smoothly commercialized.

[0009] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0016] The B electrode and the D electrode are both provided on one of the first dielectric plate and the second dielectric plate, and the second conductor and the third conductor are provided on the other of the first dielectric plate and the second dielectric plate;

[0017] During the shaking process, the first dielectric plate and the second dielectric plate move relative to each other, so that the shaking energy generating device has a first state and a second state;

[0018] In a first state, the surfaces of the A plate and the B plate are facing each other, the C plate and the D plate are staggered, the A electrode and the C electrode are simultaneously conductive with the first conductor, and the B electrode and the D electrode are simultaneously conductive with the second conductor;

[0019] In the second state, the surfaces of the A plate and the D plate face each other, the surfaces of the B plate and the C plate face each other, and the C electrode and the D electrode are simultaneously conductively connected to the third conductor.

[0020] As one embodiment, the four electrodes are simultaneously disposed on one of the first dielectric plate and the second dielectric plate, and the three conductors are simultaneously disposed on the other one of the first dielectric plate and the second dielectric plate.

[0021] As one embodiment, the four electrodes are simultaneously disposed on the first dielectric plate, and the three conductors are simultaneously disposed on the second dielectric plate.

[0022] As one embodiment, the second dielectric plate is rotatably disposed on the first dielectric plate. In a first state, the A electrode and the C electrode are in contact with the first conductor at the same time, and the B electrode and the D electrode are in contact with the second conductor at the same time; in a second state, the C electrode and the D electrode are in contact with the third conductor at the same time.

[0023] As one embodiment, the A plate and the C plate are respectively arranged at intervals on both sides of the four electrodes in the circumferential direction.

[0024] In one embodiment, the inner surface of the second dielectric plate is provided with a plurality of arcuate grooves concentrically arranged around its rotation center, and the conductors are connected to the ends of the corresponding arcuate grooves in the longitudinal direction; each of the electrodes is accommodated in one of the arcuate grooves and moves along the corresponding arcuate groove to contact the corresponding conductor during the rotation of the second dielectric plate relative to the first dielectric plate.

[0025] As one embodiment, the four electrodes are arranged on the inner surface of the first dielectric plate at intervals in a radial direction of the first dielectric plate.

[0026] As one embodiment, the arcuate slot includes a first arcuate slot, a second arcuate slot, a third arcuate slot, and a fourth arcuate slot arranged at intervals along the radial direction of the second dielectric plate, two ends of the first conductor are respectively connected to the counterclockwise ends of the first arcuate slot and the second arcuate slot, two ends of the second conductor are respectively connected to the counterclockwise ends of the third arcuate slot and the fourth arcuate slot, and two ends of the third conductor are respectively connected to the clockwise ends of the second arcuate slot and the third arcuate slot; in a first state, the second dielectric plate rotates clockwise until the A electrode, the B electrode, the C electrode, and the D electrode respectively contact the counterclockwise ends of the first arcuate slot, the fourth arcuate slot, the second arcuate slot, and the third arcuate slot; in a second state, the second dielectric plate rotates counterclockwise until the C electrode and the D electrode respectively contact the clockwise ends of the second arcuate slot and the third arcuate slot.

[0027] Another object of the present invention is to provide a shaking energy generation method, using the shaking energy generation device, comprising:

[0028] shaking the shaking energy generating device to cause the second dielectric plate to move relative to the first dielectric plate;

[0029] When moved to the first state, the surfaces of the A plate and the B plate are facing each other, and the C plate and the D plate are staggered, the A electrode and the C electrode are simultaneously conductive with the first conductor, and the B electrode and the D electrode are simultaneously conductive with the second conductor;

[0030] When moving to the second state, the surfaces of the A plate and the D plate are facing each other, the B plate and the C plate are facing each other, and the C electrode and the D electrode are simultaneously conductively connected to the third conductor;

[0031] By repeatedly shaking the shaking energy generating device, the charges on the A plate and the B plate are continuously accumulated to generate current.

[0032] In one embodiment, the relative movement of the second dielectric plate relative to the first dielectric plate is rotation.

[0033] The present invention integrates two pairs of plates onto two dielectric plates, each with electrode contacts designed to connect to the corresponding plates. A slight shake can cause the two dielectric plates to move relative to each other. During this relative movement, the relative positions of the plates and the mutual conduction between the electrode contacts change, enabling the continuous transfer and accumulation of charge between the plates, and thus achieving a cyclic and stable output of energy. The present invention eliminates the need for contact friction between the plates, minimizing the energy consumed by frictional heat generation and the shaking intensity required to drive the device. Therefore, even a slight shake can drive the system to generate electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] See Figure 2The embodiment of the present invention provides a shaking energy generating device, including a first dielectric plate 10, a second dielectric plate 20, an electrode 30 and a conductor 40. The first dielectric plate 10 is provided with an A plate 11 and a C plate 12 that are insulated from each other, and the second dielectric plate 20 is provided with a B plate 21 and a D plate 22 that are insulated from each other. The four electrodes 30: A electrode 31, B electrode 32, C electrode 33, and D electrode 34 are electrically connected to the A plate 11, B plate 21, C plate 12, and D plate 22 respectively. The three conductors 40 are insulated from each other. The dielectric layer 10 is provided with a first conductor 41, a second conductor 42 and a third conductor 43. The A electrode 31 and the C electrode 33 are provided on one of the first dielectric plate 10 and the second dielectric plate 20, and the first conductor 41 is provided on the other of the first dielectric plate 10 and the second dielectric plate 20; the B electrode 32 and the D electrode 34 are provided on one of the first dielectric plate 10 and the second dielectric plate 20, and the second conductor 42 and the third conductor 43 are provided on the other of the first dielectric plate 10 and the second dielectric plate 20.

[0046] During the shaking process, the first dielectric plate 10 and the second dielectric plate 20 move relative to each other, causing the shaking energy generator to have a first state and a second state. In the first state, the surfaces of the A plate 11 and the B plate 21 face each other, the C plate 12 and the D plate 22 are offset, the A electrode 31 and the C electrode 33 are simultaneously conductive with the first conductor 41, and the B electrode 32 and the D electrode 34 are simultaneously conductive with the second conductor 42. In the second state, the surfaces of the A plate 11 and the D plate 22 face each other, the B plate 21 and the C plate 12 face each other, and the C electrode 33 and the D electrode 34 are simultaneously conductive with the third conductor 43.

[0047] Combine Figure 2 and Figure 3 As shown, Figure 3In the figure, for ease of understanding, the symbols A, B, C, and D correspond to the A plate 11, the B plate 21, the C plate 12, and the D plate 22, respectively. The first state and the second state are respectively recorded as state 1 and state 2. When the first dielectric plate 10 and the second dielectric plate 20 move relative to each other, when they move to the first state, the surfaces of the A plate 11 and the B plate 21 face each other, completing a charge accumulation. The A plate 11 is positively charged (denoted as +Q) and the B plate is negatively charged (denoted as -Q). When the device is about to switch from the first state to the second state, the A plate 11 and the B plate 21 are separated, but the A plate 11 and the D plate 22 form a capacitor, and the facing area between the two gradually increases, and the capacitance between the two also gradually increases accordingly. The A plate 11 is positively charged, the D plate 22 is negatively charged, and the B plate 21 is negatively charged. A capacitor is formed with the C plate 12, and the facing area between the two gradually increases, and the capacitance between the two also gradually increases accordingly. The B plate carries a negative charge, and the C plate 12 carries a positive charge; when the device switches from the first state to the second state, the C electrode 33 and the D electrode 34 form a loop through the third conductor 43, and the A plate 11 and the D plate 22 are completely facing each other, and the capacitance value formed is the largest. The A plate 11 carries a positive charge +Q, and the D plate 22 carries a negative charge -Q. The B plate 21 and the C plate 12 are completely facing each other, and the capacitance value formed is the largest. The B plate carries a negative charge -Q, and the C plate 12 carries a positive charge +Q. When the first dielectric plate 10 and the second dielectric plate 20 move relative to each other during the shaking process and enter the first state again, the surfaces of the A plate 11 and the B plate 21 are again facing each other to form a capacitor. At this time, the charges of the A plate 11 and the B plate 21 are doubled, thereby realizing the accumulation of charge again. In this cycle, entering the first state once completes the charge accumulation. The device can continuously accumulate charge as it is shaken, so that the energy output by the device to the outside can also be continuously enhanced, thereby realizing continuous and efficient power supply. When the charge in the device is accumulated to the maximum value that causes the capacitance between the plates to break down, it can generally reach about 1kV-2kV, and higher energy can be obtained.

[0048] Since the electrode plates of this embodiment no longer need to rely on contact friction to generate electricity, the energy consumed in frictional heat generation can be minimized, thereby achieving higher power generation efficiency and power generation voltage.

[0049] In this embodiment, four electrodes 30 are disposed on one of the first dielectric plate 10 and the second dielectric plate 20, and three conductors 40 are disposed on the other of the first dielectric plate 10 and the second dielectric plate 20. In a more preferred embodiment, four electrodes 30 are disposed on the first dielectric plate 10, and three conductors 40 are disposed on the second dielectric plate 20.

[0050] It is understood that in other embodiments, the four electrodes 30 may be disposed simultaneously on the second dielectric plate 20, and the three conductors 40 may be disposed simultaneously on the first dielectric plate 10. Alternatively, a portion of the electrodes 30 may be disposed on the first dielectric plate 10, and another portion of the electrodes 30 may be disposed on the second dielectric plate 20, and correspondingly, a portion of the conductors 40 may be disposed on the first dielectric plate 10, and another portion of the conductors 40 may be disposed on the second dielectric plate 20.

[0051] Combine Figure 4 and Figure 5 As shown, this embodiment shows a second dielectric plate 20 rotatably disposed on a first dielectric plate 10. Bearings may be installed between the second dielectric plate 20 and the first dielectric plate 10. The first dielectric plate 10 acts as a stator, and the second dielectric plate 20 acts as a rotor. Both are disc-shaped, with the rotation center of the second dielectric plate 20 located at its center. In the first state, the A electrode 31 and the C electrode 33 simultaneously contact the first conductor 41, and the B electrode 32 and the D electrode 34 simultaneously contact the second conductor 42. In the second state, the C electrode 33 and the D electrode 34 simultaneously contact the third conductor 43. The A plate 11 and the C plate 12 are spaced apart on either side of the circumference of the four electrodes 30. In other words, the A plate 11, the four electrodes 30, and the C plate 12 are sequentially disposed circumferentially of the first dielectric plate 10.

[0052] Specifically, the inner surface of the second dielectric plate 20 can be provided with a plurality of arcuate grooves 50 concentrically arranged around its rotation center. The conductors 40 are connected to the longitudinal ends of the corresponding arcuate grooves 50. Each electrode 30 is accommodated in one of the arcuate grooves 50 and moves along the corresponding arcuate groove 50 until it contacts the corresponding conductor 40 during the rotation of the second dielectric plate 20 relative to the first dielectric plate 10. The arcuate grooves 50 can extend through the thickness of the second dielectric plate 20 to form through-holes.

[0053] Here, to facilitate design, better maintain the coordinated movement of various components, and maintain the compactness of the overall structure, the four electrodes 30 of this embodiment are disposed at intervals along the radial direction of the first dielectric plate 10 on the inner surface of the first dielectric plate 10, and the plurality of arcuate grooves are disposed at intervals along the radial direction of the second dielectric plate 20. More preferably, the A electrode 31, the B electrode 32, the C electrode 33, and the D electrode 34 are located on the same radial line of the first dielectric plate 10, and accordingly, the plurality of arcuate grooves are also located on the same radial line of the second dielectric plate 20, that is, on the same radius on the same side of the rotation center.

[0054] In other embodiments, at least two electrodes 30 may be designed on a circle with the same diameter of the first dielectric plate 10 , and corresponding arc-shaped grooves may be designed on a circle with the same diameter of the second dielectric plate 20 .

[0055] like Figure 2 As shown, the arcuate groove 50 includes a first arcuate groove 51, a second arcuate groove 52, a third arcuate groove 53, and a fourth arcuate groove 54, which are spaced apart along the radial direction of the second dielectric plate 20. The two ends of the first conductor 41 are respectively connected to the counterclockwise ends of the first arcuate groove 51 and the second arcuate groove 52, the two ends of the second conductor 42 are respectively connected to the counterclockwise ends of the third arcuate groove 53 and the fourth arcuate groove 54, and the two ends of the third conductor 43 are respectively connected to the clockwise ends of the second arcuate groove 52 and the third arcuate groove 53. Here, the specific structure of the conductor connected to the arcuate groove can be that the conductor extends into the arcuate groove and protrudes from the inner surface of the arcuate groove, so that when the corresponding electrode 30 enters the extreme position of the arcuate groove end, it can better contact with the electrode 30 to achieve electrical connection. The conductor can be a wire or various conductors, and the material is not limited.

[0056] like Figure 4 , is a structural diagram of the shaking energy generating device in the first state. In the first state, the second dielectric plate 20 rotates clockwise until the A electrode 31, the B electrode 32, the C electrode 33, and the D electrode 34 contact the counterclockwise ends of the first arc groove 51, the fourth arc groove 54, the second arc groove 52, and the third arc groove 53 respectively. At this time, the A electrode 11 and the D electrode 22 are completely opposite, and the formed capacitance value is the largest; in the second state, the second dielectric plate 20 rotates counterclockwise until the C electrode 33 and the D electrode 34 contact the clockwise ends of the second arc groove 52 and the third arc groove 53 respectively. The A electrode 11 and the D electrode 22 are completely opposite, and the formed capacitance value is the largest, and the B electrode 21 and the C electrode 12 are completely opposite, and the formed capacitance value is the largest.

[0057] It should be noted that the length of the clockwise ends of the first arc groove 51 and the fourth arc groove 54 should at least meet the requirement that when the C electrode 33 and the D electrode 34 respectively contact the clockwise ends of the second arc groove 52 and the third arc groove 53, the A electrode 31 and the B electrode 32 are in contact with the clockwise ends of the first arc groove 51 and the fourth arc groove 54 or there is still a gap.

[0058] like Figure 6 As shown, an embodiment of the present invention further provides a shaking energy generation method, comprising:

[0059] S01, shaking the shaking energy generating device to cause the second dielectric plate 20 to move relative to the first dielectric plate 10;

[0060] S02. When moved to the first state, the surfaces of the A plate 11 and the B plate 21 are facing each other, and the C plate 12 and the D plate 22 are staggered. The A electrode 31 and the C electrode 33 are simultaneously conductive with the first conductor 41, and the B electrode 32 and the D electrode 34 are simultaneously conductive with the second conductor 42.

[0061] S03. When the device moves to the second state, the surfaces of the A plate 11 and the D plate 22 face each other, the surfaces of the B plate 21 and the C plate 12 face each other, and the C electrode 33 and the D electrode 34 are simultaneously conductively connected to the third conductor 43;

[0062] S04. Repeatedly shake the shaking energy generating device, so that the charges on the A plate 11 and the B plate 21 are continuously accumulated to generate current.

[0063] Preferably, the relative movement of the second dielectric plate 20 with respect to the first dielectric plate 10 is rotation.

[0064] When the first dielectric plate 10 and the second dielectric plate 20 move relative to each other, when they move to the first state, the surfaces of the A plate 11 and the B plate 21 face each other, completing a charge accumulation, the A plate 11 carries a positive charge (denoted as +Q), and the B plate carries a negative charge (denoted as -Q); when the device is about to switch from the first state to the second state, the A plate 11 and the B plate 21 have been separated, but the A plate 11 and the D plate 22 form a capacitor, the facing area between the two gradually increases, and the capacitance between the two also gradually increases accordingly, the A plate 11 carries a positive charge, the D plate 22 carries a negative charge, and the B plate 21 carries a negative charge. A capacitor is formed with the C plate 12, and the facing area between the two gradually increases, and the capacitance between the two also gradually increases accordingly. The B plate carries a negative charge, and the C plate 12 carries a positive charge; when the device switches from the first state to the second state, the C electrode 33 and the D electrode 34 form a loop through the third conductor 43, and the A plate 11 and the D plate 22 are completely facing each other, and the capacitance value formed is the largest. The A plate 11 carries a positive charge +Q, and the D plate 22 carries a negative charge -Q. The B plate 21 and the C plate 12 are completely facing each other, and the capacitance value formed is the largest. The B plate carries a negative charge -Q, and the C plate 12 carries a positive charge +Q. When the first dielectric plate 10 and the second dielectric plate 20 move relative to each other during the shaking process and enter the first state again, the surfaces of the A plate 11 and the B plate 21 are again facing each other to form a capacitor. At this time, the charges of the A plate 11 and the B plate 21 are doubled, thereby realizing the accumulation of charge again. In this cycle, entering the first state once completes the charge accumulation. The device can continuously accumulate charge as it is shaken, so that the energy output by the device to the outside can also be continuously enhanced, thereby realizing continuous and efficient power supply. When the charge in the device is accumulated to the maximum value that causes the capacitance between the plates to break down, it can generally reach about 1kV-2kV, and higher energy can be obtained.

[0065] In addition to power generation applications, the shaking energy generation device and method of the present invention can also be used for long-distance radio transmission. By connecting a corresponding inductor to the output terminal, an oscillating circuit can be formed, transmitting electromagnetic waves at kV voltages, enabling long-distance radio transmission. Alternatively, by connecting a plasma generator to the output terminal, it can be used to generate a plasma arc, which can be used in gas detection applications.

[0066] The present invention integrates two pairs of plates onto two dielectric plates, and designs electrode contacts on the dielectric plates that connect to the corresponding plates. A slight shake can cause the two dielectric plates to move relative to each other. During this relative movement, the relative positions of the plates and the mutual conduction state between the electrode contacts change, thereby enabling the continuous transfer and accumulation of charge between the plates, and thus achieving a cyclic and stable output of energy. The present invention does not require contact friction between the plates, minimizing the energy consumed by frictional heating and the shaking intensity required to drive the device. Therefore, a slight shake can drive the system to generate electricity, making it suitable for collecting slight shakes while improving energy collection efficiency.

[0067] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
