[0002] In the related art, some power generation floors use piezoelectric ceramics to convert mechanical deformation into electrical energy for power generation.

In this structure, the effective displacement distance of the tread plate cannot be large, and the deformation of the piezoelectric ceramic itself is small, so the human body weight potential collected by the piezoelectric ceramic is small, the potential energy collection efficiency is extremely low, and the cost of the piezoelectric ceramic is high, which leads to the fact that the power generation floor can only be used as an exhibition product at present, and it is difficult to be widely used on a large scale, so it is necessary to design a new structure of a gravity potential energy collection and conversion device.

DETAILED DESCRIPTION

[0026] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0027] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inner", "outer", "vertical", "circumferential", "radial", "axial" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] In the description of this invention, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0030] Please refer to the attached diagram below. Figures 1-5 An energy storage device according to an embodiment of the present invention is described, comprising: a mounting base 1, a first spring energy storage component, a second spring energy storage component, a one-way limiting member 8, a transmission component, and a generator 9.

[0031] like Figures 3-5 As shown, the first mainspring energy storage assembly includes a first rotating shaft 2, a first mainspring 3, and a first mainspring box 4; the first rotating shaft 2 is rotatably mounted on the mounting base 1; the first mainspring 3 is sleeved on the first rotating shaft 2, and the first mainspring box 4 is sleeved on the first mainspring 3; the inner end of the first mainspring 3 is connected to the first rotating shaft 2, and the outer end is connected to the first mainspring box 4; the first mainspring box 4 is rotatably mounted on the mounting base 1; wherein, the rotation of the first rotating shaft 2 can tighten the first mainspring 3, and the first mainspring 3 can drive the first mainspring box 4 to rotate.

[0032] Specifically, since the first shaft 2 can only rotate in one direction, when the first shaft 2 rotates, it will only tighten the first spring 3 to convert the rotational kinetic energy into the elastic potential energy of the first spring 3 and store it. After the first spring 3 is tightened, it will drive the first spring box 4 to rotate during the process of releasing the elastic potential energy.

[0033] The second mainspring energy storage assembly includes a second rotating shaft 5, a second mainspring 6, and a second mainspring box 7. The second rotating shaft 5 is rotatably mounted on the mounting base 1. The second mainspring 6 is sleeved on the second rotating shaft 5, and the second mainspring box 7 is covered on the second mainspring 6. The inner end of the second mainspring 6 is connected to the second rotating shaft 5, and the outer end is connected to the second mainspring box 7. The second mainspring box 7 is rotatably mounted on the mounting base 1. The rotation of the second rotating shaft 5 can tighten the second mainspring 6, and the second mainspring 6 can drive the second mainspring box 7 to rotate.

[0034] Specifically, since the second rotating shaft 5 can only rotate in one direction, when the second rotating shaft 5 rotates, only the second spring 6 will be tightened to store the elastic potential energy of the second spring 6, and after the second spring 6 is tightened, in the process of releasing the elastic potential energy, the second spring box 7 will be driven to rotate.

[0035] As shown in Figures 3-5 The one-way limiting piece 8 is arranged on the mounting seat 1, and the one-way limiting piece 8 is configured to fix the second spring box 7 when the stored energy of the first spring 3 is greater than the stored energy of the second spring 6, and fix the first spring box 4 when the stored energy of the second spring 6 is greater than the stored energy of the first spring 3; the first spring box 4 and the second spring box 7 are connected with the transmission assembly and driven to rotate the motor shaft 10 of the generator 9 through the transmission assembly.

[0036] The working principle of the device will be described in detail below when the device is applied to a power generation floor.

[0037] The power generation floor usually has a base and a treadable pressing plate which can swing up and down and is installed on the base. The device is installed on the base, and the first rotating shaft 2 and the second rotating shaft 5 are connected with the treadable pressing plate through a transmission mechanism. When a human body treads the treadable pressing plate, the treadable pressing plate will swing down and drive the first rotating shaft 2 and the second rotating shaft 5 to rotate, so as to convert the gravitational potential energy of the human body into the rotational kinetic energy of the first rotating shaft 2 and the second rotating shaft 5.

[0038] It can be understood that since the downward displacement degree of different position points is different when the treadable pressing plate swings down, the rotational kinetic energy of the first rotating shaft 2 and the second rotating shaft 5 is different, and then the stored energy of the first spring 3 and the second spring 6 is different. A one-way limiting piece 8 is arranged in the device, which can fix the spring box with smaller energy storage. Thus, the spring box with larger energy storage can be rotated to release the elastic potential energy for conversion into electric energy. In the process of releasing, the first spring 3 and the second spring 6 can continue to store energy and perform a new round of energy comparison and release the energy of the spring with larger energy storage for conversion into electric energy by continuously treading the treadable pressing plate by the human body.

[0039] In summary, and different from the prior art power generation floor which converts the tiny mechanical deformation of piezoelectric ceramics into electric energy, the applicant provides a new form of potential energy collection and conversion of electric energy. The device uses two spring energy storage assemblies to simultaneously collect the gravitational potential energy of different dispersed points, and then stores the gravitational potential energy into the corresponding springs. Then, the energy of the spring with larger energy storage is released to convert into electric energy by the action of the one-way limiting piece 8. In the process of releasing, the two spring energy storage assemblies can simultaneously continue to store energy and perform a new round of comparison and release, so that the gravitational potential energy can be more fully converted into electric energy, and the collection and conversion efficiency is higher. The device can replace the piezoelectric ceramic power generation mode, reduce the comprehensive cost of the gravitational potential energy power generation mode, and realize more efficient collection and utilization of gravitational potential energy and energy conversion.

[0040] It can be understood that the energy storage device of the application can be used for energy collection and power generation in various forms and multiple positions in other fields in addition to the gravitational potential energy collection and power generation of the power generation floor, and has wider and more flexible application modes and ranges.

[0041] The specific structure of the device will be described in detail below.

[0042] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the mounting seat 1 includes a connecting plate 23, a first mounting plate 24, a second mounting plate 25 and a partition plate 26. The first mounting plate 24 and the second mounting plate 25 are oppositely arranged and spaced apart. The partition plate 26 is arranged between the first mounting plate 24 and the second mounting plate 25. The connecting plate 23 is connected with the first mounting plate 24, the second mounting plate 25 and the third mounting plate respectively.

[0044] In this embodiment, as shown in Figure 1 and Figure 2 , the first rotating shaft 2 is rotatably connected with the first mounting plate 24.

[0045] Specifically, as shown in Figure 1 and Figure 2 , the transmission forms here all adopt gear transmission, the gear transmission form is stable, high in precision and reliable in transmission. Among them, the first gear 12 is arranged on the side surface of the first spring box 4 close to the middle partition plate 26, the second gear 13 is arranged on the side surface of the second spring box 7 close to the middle partition plate 26, in order to prevent the first spring box 4 or the second spring box 7 from affecting the other spring box when rotating, the third gear 14 and the fourth gear 15 are both rotatably installed on the transmission shaft 16.

[0046] In the embodiment, as shown in Figure 3 , the third gear 14 and the transmission shaft 16 are provided with a third one-way bearing 17, and the fourth gear 15 and the transmission shaft 16 are provided with a fourth one-way bearing, so that the third gear 14 and the fourth gear 15 can rotate in one direction.

[0047] In the embodiment, as shown in Figure 1 , one end of the transmission shaft 16 is provided with a first bevel gear 18, and the motor shaft 10 is provided with a second bevel gear 19, the first bevel gear 18 is engaged with the second bevel gear 19, so that the overall structure of the device is more compact.

[0048] In the embodiment, as shown in Figure 3 and Figure 4 , one end of the first rotating shaft 2 close to the middle partition plate 26 is provided with a first recess 27, the first spring box 4 and the first gear 12 are provided with a first through hole 28, one end of the second rotating shaft 5 close to the middle partition plate 26 is provided with a second recess, the second spring box 7 and the second gear 13 are provided with a second through hole, and the middle partition plate 26 is fixedly provided with a central shaft 29, one end of the central shaft 29 extends into the first recess 27 through the first through hole 28, and the other end extends into the second recess through the second through hole.

[0049] Specifically, the axial ends of the central shaft 29 protrude from the partition plate 26, so that the first rotating shaft 2, the first spring box 4 and the first gear 12 can be sleeved with the axial end of the central shaft 29, and the second rotating shaft 5, the second spring box 7 and the second gear 13 can be sleeved with the axial end of the central shaft 29, so that the central shaft 29 can support the first rotating shaft 2, the first spring box 4, the first gear 12, the second rotating shaft 5, the second spring box 7 and the second gear 13, and the coaxial arrangement is achieved, so that the structure is compact and the components are not easy to shake.

[0050] Further, in order to reduce the rotating friction, bushings can be arranged in the first groove 27, the first through hole 28, the second groove and the second through hole, and the central shaft 29 is arranged in the bushings.

[0051] In the embodiment, as shown in Figure 3 and Figure 4 , the one-way limiting member 8 is a limiting ball, the mounting seat 1 (i.e., the partition plate 26 in the above) is provided with a sliding through hole 20, the limiting ball is arranged in the sliding through hole 20 and can reciprocate along the axial direction of the sliding through hole 20; the first gear 12 is located on one side of the axial direction of the sliding through hole 20, and the second gear 13 is located on the other side of the axial direction of the sliding through hole 20; the surface of the first gear 12 close to the sliding through hole 20 is provided with a first limiting hole 21, and the surface of the second gear 13 close to the sliding through hole 20 is provided with a second limiting hole 22; a part of the limiting ball is located in the sliding through hole 20, and a part of the limiting ball is located in the first limiting hole 21 or the second limiting hole 22 to fix the first gear 12 or the second gear 13.

[0052] Specifically, it is assumed that when the initial state, the energy of the first spring 3 is greater than that of the second spring 6, at this time, the first gear 12 rotates to release the energy of the first spring 3, and the side close to the partition plate 26 will push the limiting ball to be clamped into the second limiting hole 22 to fix the second gear 13; when the first gear 12 rotates to the first limiting hole 21 opposite to the sliding through hole 20, if the energy of the second spring 6 is greater than that of the first spring 3 at this time, the side close to the partition plate 26 of the second gear 13 will push the limiting ball to be clamped into the first limiting hole 21 to fix the first gear 12, and the second gear 13 starts to rotate to release the energy of the second spring 6; when the second gear 13 rotates to the second limiting hole 22 opposite to the sliding through hole 20, if the energy of the first spring 3 is greater than that of the second spring 6 at this time, the first gear 12 will push the limiting ball to be clamped into the second limiting hole 22 to fix the second gear 13. Such a cycle is repeated, and the periodic comparison of the energy of the first spring 3 and the second spring 6 is repeated, so that the limiting ball moves automatically, and the energy of the spring with greater energy is always released and converted into electrical energy, and the spring with smaller energy can continue to be tightened to store energy, thereby effectively improving the efficiency of collecting and converting gravitational potential energy. Moreover, under this structure, the movement of the limiting ball is mechanical and automatic, and the work is reliable and does not need to be maintained frequently.

[0053] Further, when a part of the limiting ball is located in the first limiting hole 21, the limiting ball is tangent to the side of the second gear 13 close to the middle partition plate 26, thereby reducing the influence of the limiting ball on the rotation of the second gear 13; when a part of the limiting ball is located in the second limiting hole 22, the limiting ball is tangent to the side of the first gear 12 close to the middle partition plate 26, thereby reducing the influence of the limiting ball on the rotation of the first gear 12.
