Description

Technical Field

[0001] This invention relates to the field of power generation floor technology, and more particularly to an energy storage device, a step-on power generation floor, and an energy storage and power generation method. Background Technology

[0002] In the current field of power generation flooring, the tiny mechanical deformation of piezoelectric ceramics is converted into electrical energy. However, the mechanical limiting structure restricts the descent distance of the panel, and the effective displacement distance of the panel cannot be very large. Furthermore, the deformation of the piezoelectric ceramic itself is very small. Therefore, very little gravitational potential energy of the human body can be collected by the deformation of the piezoelectric ceramic, resulting in extremely low potential energy collection efficiency.

[0003] In the current field of power generation flooring, spring-loaded energy storage components are used to directly collect gravitational potential energy from different dispersed points, then store it in the corresponding springs, and convert the gravitational potential energy into electrical energy.

[0004] However, when the spring is wound up and stores enough energy, it needs to release energy to generate electricity. After the spring releases energy, it needs to be wound up again to continue storing energy. Existing spring-loaded springs have difficulty switching between winding and storing energy and releasing energy to generate electricity. This results in poor user experience.

[0005] Furthermore, the direct drive connection structure between the spring and the panel in the existing power generation floor is also difficult to meet the switching between spring winding for energy storage and energy release for power generation.

[0006] Furthermore, the mainspring requires a significant force to wind, necessitating considerable stomping force from the user to activate the control panel and wind the mainspring, thus storing gravitational potential energy. This results in poor user experience. Summary of the Invention

[0101] Base;

[0102] Panel, the panel being omnidirectionally connected to the base; and

[0103] The aforementioned energy storage device;

[0104] The pedal transmission mechanism is configured such that, during the process of the panel being stepped down, it can drive the first limiting member to switch between the locked position and the unlocked position through the second transmission component, and can drive the inner ring of the mainspring to rotate and tighten the mainspring when the second limiting member is in the locked position.

[0105] According to a third aspect of the present invention, a method for energy storage and power generation using a step-activated power generation floor is provided, wherein the step-activated power generation floor includes a panel and an energy storage device, the energy storage device including a step-driven transmission assembly, a spring, a second transmission assembly, and a first limiting member capable of switching between a locked position and an unlocked position. The energy storage and power generation method includes the following steps:

[0106] The first limiting component is in the locking position that prevents the outer coil of the mainspring from rotating. When the panel is stepped on and moved down, the inner coil of the mainspring rotates through the pedal transmission component, thereby winding the mainspring.

[0107] The panel is stepped on and moved down, which in turn drives the first limiting member to the unlock position via the step transmission component and the second transmission component, thus unlocking the outer ring of the mainspring.

[0108] The outer coil of the mainspring rotates, thereby driving the generator shaft to rotate, which in turn generates electricity.

[0109] The pedal transmission component drives the first limiting member to move to the locked position through the second transmission component, so as to cycle through the energy storage and power generation method.

[0110] Optionally, the energy storage device includes a first gear, a second gear, a mainspring barrel, a first elastic element, a third transmission assembly, and a second rotating shaft; the first gear is connected to the inner ring of the mainspring, the mainspring barrel covers the mainspring and is fixed to the outer ring of the mainspring, and multiple second tooth grooves are provided on the outer peripheral wall of the mainspring barrel; a second pawl is provided at one end of the first limiting element; the second transmission assembly includes a third gear, a worm, a worm wheel, a first rotating shaft, and a swinging element; one end of the swinging element is fixedly connected to the first rotating shaft, and the other end is suspended; the third gear is coaxially fixed with the worm, the worm meshes with the worm wheel, the worm wheel is sleeved on the first rotating shaft, and the second gear meshes with both the first gear and the third gear; the energy storage power generation method includes:

[0111] The second pawl on the first limiting member in the locking position is inserted into the second tooth groove to prevent the outer coil of the mainspring from rotating; the panel is stepped down and drives the second gear to rotate through the pedal transmission assembly, the second gear drives the first gear to rotate, the first gear drives the inner coil of the mainspring to rotate, thereby winding the mainspring; and the second gear drives the third gear and the worm to rotate, the worm drives the worm wheel and the first rotating shaft to rotate, thereby driving the oscillating member to rotate.

[0112] The first rotating shaft drives the swing member to rotate until the other end of the swing member abuts against the other end of the first limiting member and drives the first limiting member to rotate until the second pawl disengages from the unlocking position of the second tooth groove, thereby unlocking the outer ring of the mainspring, and the first elastic member elastically deforms.

[0113] The outer ring of the mainspring rotates, which drives the second shaft to rotate via the third transmission assembly. The second shaft then drives the generator's motor shaft to rotate, thereby generating electricity.

[0114] The first rotating shaft drives the oscillating member to rotate until the other end of the oscillating member separates from the other end of the first limiting member. The first elastic member is then released elastically, thereby driving the first limiting member to rotate to the locked position, so as to cycle through the energy storage and power generation method.

[0115] The beneficial effects of this invention include:

[0116] In this invention, when the panel is stepped on and moved downwards, the stepping transmission mechanism can drive the first limiting member to switch between a locked position and an unlocked position via the second transmission component. When the first limiting member is in the locked position, the stepping transmission mechanism can drive the first gear to rotate unidirectionally, thereby winding the mainspring to store energy. When the first limiting member is in the unlocked position, the outer coil of the mainspring can rotate to release the stored energy and generate electricity. The energy storage and release of the energy storage device are carried out in a sequential cycle, improving the efficiency of energy storage and power generation, and achieving a high degree of automation. It is energy-saving and environmentally friendly.

[0117] By incorporating a foot-operated transmission mechanism and gear assembly, the distance of power movement is reduced, converting the small downward movement of the panel into a larger rotation angle of the second gear, thereby increasing the winding speed of the mainspring and improving energy storage and power generation efficiency. The structure is streamlined and occupies little space. The linkage ratio of the foot-operated transmission mechanism is adjustable, allowing the minimum force required to move the panel downwards to be set according to needs, resulting in a superior user experience.

[0118] The height of the pedal transmission mechanism, the second gear, the first gear, and the second transmission component can be set relatively low, resulting in a smaller overall height of the energy storage device and a smaller footprint in the internal space of the pedal-powered floor.

[0119] The first rotating shafts of multiple energy storage devices are connected by a first flexible shaft, and the first rotating shafts of multiple energy storage devices can be linked together through the first flexible shaft, so as to realize the sequential release of the stored energy of multiple energy storage devices.

[0120] The second shafts of multiple energy storage devices can be linked together via a second flexible shaft and connected to the motor shaft of the same generator, eliminating the need for multiple generators. This design is compact and occupies little space.

[0121] The energy storage device, the step-powered power generation floor, and the energy storage and power generation method provided by this invention can generate electricity using human power, which is green, healthy, energy-saving, and environmentally friendly.

[0188] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention. Detailed Implementation

[0189] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0190] According to one embodiment of the present invention, a step-powered power generation floor is provided. Please refer to [link / reference]. Figure 1 The step-powered power generation floor includes a panel, a base 9, and multiple energy storage devices 1. The panel is connected to the base 9 via a universal joint structure, allowing the panel to swing in all directions. A gap is provided between the base 9 and the panel. The energy storage devices 1 are positioned between the base 9 and the panel. When the panel is stepped on, the corresponding area of ​​the panel moves downwards.

[0191] Please see Figure 2 and Figure 3 The energy storage device 1 includes a support base 50, a top cover 66, a first support shaft 51, a mainspring, a first gear 12, a mainspring barrel 13, a second support shaft 52, a first limiting member 44, a second limiting member 42, a first elastic member, a second gear 22, a second transmission assembly, and a pedal transmission mechanism 70. The energy storage device 1 can be mounted on the base 9 via the support base 50.

[0192] The first support shaft 51 is arranged perpendicular to the support base 50. The first support shaft 51 is rotatably mounted on the support base 50 and can rotate about its axis.

[0193] The mainspring is mounted on the first support shaft 51. The inner wall of the mainspring is fixedly connected to the first support shaft 51. When the first support shaft 51 rotates, it can drive the inner wall of the mainspring to rotate together.

[0194] The first gear 12 is sleeved on the first support shaft 51, and the first gear 12 is fixedly connected to the first support shaft 51. Thus, the first gear 12, fixedly sleeved on the first support shaft 51, can rotate on the support seat 50. When the first gear 12 rotates, it drives the first support shaft 51 to rotate, thereby driving the inner ring of the mainspring to rotate.

[0195] The mainspring barrel 13 covers the mainspring. The mainspring barrel 13 is fixedly connected to the outer ring of the mainspring. The outer ring of the mainspring can rotate together with the mainspring barrel 13 or be fixed circumferentially.

[0196] The second support shaft 52 is mounted on the support base 50. The axial direction of the second support shaft 52 is perpendicular to the support base 50. The second support shaft 52 is fixedly connected to the support base 50.

[0197] The first limiting member 44 is rotatably connected to the second support shaft 52. The first limiting member 44 can rotate to different positions relative to the second support shaft 52. The first limiting member 44 can move to a locked position or an unlocked position. A second pawl is provided at one end 422 of the first limiting member 44.

[0198] Correspondingly, a plurality of teeth 14 are provided on the outer peripheral wall of the spring box 13. A second tooth groove is provided between adjacent teeth 14. The structure of the second pawl is configured to cooperate with the structure of the second tooth groove so that: the second pawl can be inserted into the second tooth groove to place the first limiting member 44 in the locked position, or the second pawl can be disengaged from the second tooth groove to place the first limiting member 44 from the locked position to the unlocked position.

[0199] One end of the second limiting member 42 is rotatably connected to the second support shaft 52, and the other end of the second limiting member 42 can rotate around the second support shaft 52. The other end of the second limiting member 42 is provided with a first pawl. The structure of the first pawl is configured to cooperate with the first tooth groove structure of the first gear 12, so that: the first pawl can be inserted into the first tooth groove to place the second limiting member 42 in the locked position, or the first pawl can disengage from the first tooth groove to disengage the second limiting member 42 from the locked position.

[0200] The first elastic element can be a torsion spring. One end of the torsion spring is connected to the second limiting member 42, and the other end is connected to the first limiting member 44. In the initial state, the torsion spring undergoes elastic deformation, and its own elastic force can cause the two ends of the torsion spring to have a tendency to move relative to each other, so that one end of the torsion spring applies an elastic locking force to the second limiting member 42, and the other end of the torsion spring applies an elastic locking force to the first limiting member 44.

[0201] The elastic locking force applied by the first elastic member to the first limiting member 44 keeps the first limiting member 44 in the locked position. When the first limiting member 44 is in the locked position, the second claw is inserted into the second tooth groove. At this time, the first limiting member 44 is snapped into the outer coil of the mainspring, and the first limiting member 44 can prevent the outer coil of the mainspring from rotating.

[0202] The second gear 22 is connected to the first limiting member 42 via the second transmission assembly, and is used to drive the first limiting member 42 to reciprocate around the second support shaft 52, so that the first limiting member 42 can switch between the locked position and the unlocked position.

[0203] The elastic locking force applied by the first elastic member to the second limiting member 42 keeps the second limiting member 42 in the locked position. When the second limiting member 42 is in the locked position, the first pawl is inserted into the first tooth groove of the first gear 12. At this time, the second limiting member 42 is snapped into the first gear 12, and the second limiting member 42 can prevent the first gear 12 from rotating in the opposite direction, so that the first gear 12 can only rotate in one direction.

[0204] The second gear 22 is rotatably connected to the support base 50. The second gear 22 meshes with the first gear 12.

[0205] When the first limiting member 42 is in the locked position, the outer ring of the mainspring is prevented from rotating; at this time, the second gear 22 can drive the first gear 12 to rotate in one direction, thereby driving the inner ring of the mainspring to rotate and tightening the mainspring to store energy.

[0206] When the first limiting member 44 is disengaged from the locked position, the outer ring of the mainspring is allowed to rotate; if the mainspring is in a wound state at this time, the outer ring of the mainspring will rotate to release the mainspring's stored energy.

[0207] The panel can be driven to the second gear 22 via a foot-operated transmission mechanism 70. Thus, the panel is driven to the energy storage device 1. When the panel is stepped on and moved downwards, it drives the second gear 22 to rotate.

[0208] The second gear 22 is connected to the first limiting member 44 via the second transmission assembly. When the panel is stepped on and moved down, causing the second gear 22 to rotate, the first limiting member 44 can be switched between the locked and unlocked positions via the second transmission assembly.

[0209] As the panel is stepped on and moved down, causing the second gear 22 to rotate, when the second gear 22 drives the first limiting member 44 to move to the locked position through the second transmission component, the second gear 22 can drive the first gear 12 to rotate in one direction, thereby driving the mainspring to rotate inward and tighten the mainspring.

[0210] Understandably, when the panel begins to be stepped on and moved down, the second gear 22 will drive the first gear 12 to rotate in one direction. The second gear 22 receives the transmission force and abuts against the first gear 12. The first gear 12 abuts against the second limiting member 42, which can overcome the elastic locking force applied by the first elastic member to the second limiting member 42. The second limiting member 42 can be abutted and rotated by the first gear 12 to the unlocked position, so that the first pawl disengages from the first tooth groove, so that the second gear 22 continues to drive the first gear 12 to rotate in one direction.

[0211] As the panel is stepped on and moved down, causing the second gear 22 to rotate, when the second gear 22 drives the first limiting member 44 to move to the unlocked position through the second transmission component, the first limiting member 44 disengages from the outer ring of the mainspring, and the outer ring of the mainspring rotates to release the stored energy of the mainspring.

[0212] In this embodiment, please refer to Figure 4 and Figure 5 A fourth support shaft 25 is protruding from the support base 50. The axis of the fourth support shaft 25 is perpendicular to the support base 50, and the fourth support shaft 25 is rotatably connected to the support base 50.

[0213] The second gear 22 includes a second pinion 224 and a second large gear 222. The second large gear 222 is fixedly mounted on the fourth support shaft 25. The second large gear 222 meshes with the first gear 12 and the third gear 31 in the second transmission assembly.

[0214] The second pinion 224 is mounted on the fourth support shaft 25, and a first one-way bearing 21 is provided between the second pinion 224 and the fourth support shaft 25. The pitch circle diameter of the second large gear 222 is larger than that of the second pinion 224. The pitch circle diameter of the second large gear 222 is larger than that of the first gear 22.

[0215] The second pinion 224 is connected to the panel drive. Because a first one-way bearing 21 is provided between the second pinion 224 and the fourth support shaft 25, the second pinion 224 can only drive the second large gear 222 to rotate in one direction through the fourth support shaft 25.

[0216] The panel is connected to the second pinion 224 via a step-on power generation floor 7. Because a first one-way bearing 21 is provided between the second pinion 224 and the fourth support shaft 25, the second pinion 224 can only drive the second large gear 222 to rotate in one direction via the fourth support shaft 25.

[0217] A rotating rod 27 is provided on the fourth support shaft 25, around which it can rotate. One end of the rotating rod 27 is rotatably sleeved on the fourth support shaft 25, so that the rotating rod 27 can rotate around the fourth support shaft 25. The other end of the rotating rod 27 is provided with a rotatable roller 26, which can rotate around its axis. The roller 26 and the second pinion 224 are radially spaced apart by a receiving portion 28 for inserting the rack 72 of the pedal transmission mechanism 70.

[0218] In this embodiment, please refer to Figure 4 and Figure 5 The second transmission assembly includes a first rotating shaft 56, a swing element 57, a third gear 31, a worm 32, and a worm wheel 33.

[0219] The second gear 22 is connected to the third gear 31 in a transmission connection. Specifically, the second gear 222 of the second gear 22 meshes with the third gear 31 in the second transmission assembly. The pitch circle diameter of the second gear 222 is larger than that of the third gear 31.

[0220] A fifth support shaft 34 is provided on the support base 50. The axis of the fifth support shaft 34 is perpendicular to the support base 50. The fifth support shaft 34 is rotatably connected to the support base 50. The third gear 31 and the worm gear 32 are coaxially fixed through the fifth support shaft 34. In this way, the third gear 31 and the worm gear 32 can rotate together.

[0221] The worm gear 33 is mounted on the first rotating shaft 56. A second one-way bearing 58 is provided between the worm gear 33 and the first rotating shaft 56. When the worm gear 33 rotates, it can drive the first rotating shaft 56 to rotate; when the first rotating shaft 56 rotates, it cannot drive the worm gear 33 to rotate.

[0222] The worm 32 meshes with the worm wheel 33, and together they form a worm gear mechanism. When the worm 32 rotates, it drives the worm wheel 33 to rotate.

[0223] One end of the swing member 57 is fixedly connected to the first rotating shaft 56, and the other end is suspended in the air. When the first rotating shaft 56 rotates, the other end of the swing member 57 rotates around the first rotating shaft 56.

[0224] The two ends of the first limiting member 44 are located on the radial sides of the second support shaft 52, respectively. The other end of the swing member 57 is located on one side of the other end 444 of the first limiting member 44.

[0225] When the first rotating shaft 56 is driven to rotate, the first rotating shaft 56 drives the swing member 57 to rotate, so that the other end of the swing member 57 abuts against the other end 444 of the first limiting member 44, thereby driving the first limiting member 44 to rotate to the unlock position, or causing the other end of the swing member 57 to separate from the other end of the first limiting member 44, so that the first elastic member can drive the first limiting member 44 to reset to the locked position.

[0226] When the panel is stepped on and moved down, it can drive the second gear 22 to rotate. The second gear 22 drives the third gear 31 and the worm gear 32 to rotate, thereby driving the worm wheel 33 and the first rotating shaft 56 to rotate in one direction, which in turn drives the swing member 57 to rotate, so that the other end of the swing member 57 drives the first limiting member 44 to rotate to the unlocked position or the locked position.

[0227] Of course, in some other embodiments, the second transmission component may also adopt other transmission mechanisms, such as chain drive mechanism, worm gear mechanism, cam mechanism, rod drive mechanism, etc., or a combination of one or more of them.

[0228] Please see Figure 4 and Figure 5 The energy storage device 1 also includes a third support shaft 53, a third transmission assembly, a second rotating shaft 54, and a generator. The third transmission assembly includes an eighth gear 61, a fifth gear 62, and a sixth gear 63.

[0229] The eighth gear 61 is rotatably mounted on the first support shaft 51. The eighth gear 61 is fixedly connected to the mainspring barrel 13. The eighth gear 61 can rotate together with the mainspring barrel 13.

[0230] The third support shaft 53 is axially perpendicular to the surface of the support base 50, and is rotatably connected to the support base 50. The fifth gear 62 is sleeved on the third support shaft 53. The eighth gear 61 meshes with the fifth gear 62.

[0231] The fifth gear 62 and the sixth gear 63 are coaxially fixed by the third support shaft 53, and the fifth gear 62 and the sixth gear 63 can rotate together.

[0232] The second rotating shaft 54 ​​is axially perpendicular to the first support shaft 51. The second rotating shaft 54 ​​is axially parallel to the surface of the support base 50. The second rotating shaft 54 ​​is coaxially fixed with the generator's motor shaft.

[0233] A seventh gear 64 is mounted on the second rotating shaft 54. A third one-way bearing 65 is provided between the seventh gear 64 and the second rotating shaft 54. When the seventh gear 64 rotates, it can drive the second rotating shaft 54 ​​to rotate, but when the second rotating shaft 54 ​​rotates, it cannot drive the seventh gear 64 to rotate.

[0234] The sixth gear 63 is a helical gear. The seventh gear 64 is also a helical gear. The sixth gear 63 and the seventh gear 64 are meshing helical gears. Thus, the mainspring barrel 13 is connected to the seventh gear 64 via the third transmission assembly.

[0235] When the outer ring of the mainspring rotates to release the energy stored in the mainspring, the outer ring of the mainspring drives the mainspring box 13 to rotate. The mainspring box 13 drives the eighth gear 61 to rotate, which in turn drives the fifth gear 62 and the sixth gear 63 to rotate, which in turn drives the seventh gear 64 and the second shaft 54 ​​to rotate, thereby driving the generator's motor shaft to rotate.

[0236] Please see Figure 2 The top cover 66 can be placed on the support base 50. There is a space between the top cover 66 and the support base 50 to accommodate the components. The top cover 66 can protect the components within the space and prevent them from being damaged.

[0237] In this embodiment, please refer to Figure 1 There are multiple energy storage devices 1. The first rotating shafts 56 of the multiple energy storage devices 1 are connected by a first flexible shaft. The first rotating shafts 56 of the multiple energy storage devices 1 can be linked together by the first flexible shaft. The second rotating shafts 54 of the multiple energy storage devices 1 can be linked together by a second flexible shaft and connected to the motor shaft of the same generator. The structure is simple and occupies little space.

[0238] When the first shaft 56 of any one energy storage device 1 rotates, it can drive the first shaft 56 of the other energy storage devices 1 to rotate, thereby enabling the sequential release of multiple energy storage devices 1.

[0239] It is understandable that the unlocking positions of the first rotating shaft 56 of the multiple energy storage devices 1 can be set differently, thereby realizing the sequential release of the stored energy of the multiple energy storage devices 1.

[0240] The number of energy storage devices 1 can be specifically set according to the internal space of the power generation floor, such as two, three, four, five, six or other numbers. The arrangement of multiple energy storage devices 1 on the base 9 can be specifically set as needed.

[0241] Please see Figure 2 and Figure 6 The pedal transmission mechanism 70 includes a first pedal lever 74, a linkage mechanism 80, and a rack 72. The rack 72 is inserted into the receiving portion 28 so that the rack 72 meshes with the second pinion 224 of the second gear 22.

[0242] The roller 26 is located on the side of the rack 72 facing away from the second pinion 224. The roller 26 can block and limit the second pinion 224, so that the rack 72 and the second pinion 224 always remain engaged. In this way, the pedal transmission mechanism 70 is connected to the mainspring drive through the second gear 22 and the first gear 12, and is used to drive the inner ring of the mainspring to rotate.

[0243] When the panel is stepped on and moved down, the stepping on the power generation floor 7 drives the second pinion 224 to rotate through the rack 72, and the second pinion 224 drives the second large gear 222 to rotate through the fourth support shaft 25.

[0244] When the panel is moved back to its original position, stepping on the power generation floor 7 drives the second pinion 224 to rotate via the rack 72. However, at this time, the second pinion 224 cannot drive the second large gear 222 to rotate via the fourth support shaft 25.

[0245] The first end of the first pedal lever 74 is rotatably connected to the first fulcrum, and the first pedal lever 74 rotates around the first fulcrum. The second end of the first pedal lever 74 is connected to the rack 72 via a linkage mechanism 80.

[0246] The first fulcrum can be set on the base 9. The first end of the first pedal 74 can be rotatably connected to the first fulcrum of the base 9 via the first connecting shaft 75.

[0247] When the first pedal 74 is subjected to a stepping force, the first pedal 74 can rotate around the first fulcrum, thereby pulling the rack 72 through the linkage mechanism 80, so that the rack 72 drives the second gear 22 of the energy storage device 1 to rotate.

[0248] In this embodiment, please refer to Figure 6The pedal transmission mechanism 70 may further include a second pedal rod 76, a third pedal rod 78, and a second elastic element. The first end of the second pedal rod 76 is rotatably connected to a second fulcrum, and the second pedal rod 76 can rotate around the second fulcrum. The second pedal rod 76 is the same length as the first pedal rod 74.

[0249] The second fulcrum can be set on the base 9. The first end of the second pedal 76 can be rotatably connected to the second fulcrum of the base 9 via a pivot structure.

[0250] The third pedal 78 is rotatably connected to the second end of the first pedal 74 and the second end of the second pedal 76. The second pedal 76 is arranged parallel to the first pedal 74. The third pedal 78 is located below the panel.

[0251] The first pedal 74 and the second pedal 76 can jointly support the third pedal 78, so that the third pedal 78 has a certain height and can move up and down between the base 9 and the panel.

[0252] The extension length of the third pedal 78 can be set to be larger, and the area that can drive the first pedal to rotate when the panel is stepped on will increase accordingly.

[0253] The second elastic element is made of a material with good elasticity, and it can undergo elastic deformation when subjected to force. One end of the second elastic element is connected to the third pedal 78, and the other end is connected to the base 9 or the panel. Specifically, the second elastic element can be a spring disposed between the third pedal 78 and the base 9.

[0254] When the panel is stepped on, the third foot pedal 78 can be moved downward under force. At this time, during the downward movement of the third foot pedal 78, the second elastic element can undergo elastic deformation; and a stepping force is applied to the first foot pedal 74, thereby causing the first foot pedal 74 to rotate around the first fulcrum; and a stepping force is applied to the second foot pedal 76, thereby causing the second foot pedal 76 to rotate around the second fulcrum.

[0255] When the force on the third pedal 78 disappears, the elastic force of the second elastic element is released, thereby causing the third pedal to move upward and reset.

[0256] The linkage mechanism 80 can be specifically configured as needed, as long as it can connect the first pedal lever 74 to the gear transmission and convert the rotational motion of the first pedal lever 74 into the activity of the rack 72 driving the second gear 22 to rotate.

[0257] In this embodiment, please refer to Figure 6 and Figure 7 The linkage mechanism 80 includes a second link 802, a third link 803, a fourth link 804, a fifth link 805, a sixth link 806, and a seventh link 807.

[0258] The first end of the second link 802 is rotatably connected to the first pedal lever 74 via a rotating shaft structure. The second end of the second link 802 is rotatably connected to the first end of the third link 803 via a second connecting shaft 809. A rolling element 84 is rotatably sleeved on the second connecting shaft 809.

[0259] The pedal transmission mechanism 70 also includes a support member 82. The support member 82 can be fixedly mounted on the base 9. The rolling member 84 can be rolled on the surface of the support member 82. When the rolling member 84 rotates around the second connecting shaft 809, it can simultaneously roll on the second connecting shaft 809.

[0260] The rolling element 84 can be configured as a bearing sleeved on the second connecting shaft 809. The friction between the bearing and the second connecting shaft 809 is small, making it easy for the bearing to rotate around the second connecting shaft 809.

[0261] The bearing 82 can be a steel plate fixed to the base 9. The low friction between the bearing and the steel plate makes it easy for the bearing to roll on the steel plate.

[0262] The first connecting shaft 75 and the second connecting shaft 809 are aligned in the horizontal X direction. A clearance through hole 803A is provided on the third connecting rod 803. The clearance through hole 803A passes through the three connecting rods. The clearance through hole 803A extends in the horizontal X direction. The first connecting shaft 75 passes through the clearance through hole 803A, ensuring that the first connecting shaft 75 does not obstruct the third connecting rod 803 laterally, allowing the third connecting rod 803 to slide in the horizontal X direction.

[0263] The first pedal lever 74, the second connecting rod 802, and the third connecting rod 803 (partial structure 803B) together form a triangle. The first pedal lever 74 and the third connecting rod 803 (partial structure 803B) form a variable acute angle. The second connecting rod 802 and the third connecting rod 803 (partial structure 803B) also form a variable acute angle.

[0264] The second end of the third link 803 can be rotatably connected to the first end of the fourth link 804 via a pivot structure. In this way, the first end of the fourth link 804 is connected to the second end of the first pedal lever 74 via the third link 803 and the second link 802.

[0265] The second end of the fourth link 804 is rotatably connected to the fourth fulcrum via the sixth link 806. The fourth fulcrum may be located on the support base 50 and / or the top cover 66.

[0266] The first end of the sixth link 806 can be rotatably connected to the fourth link 804 via a rotating shaft structure, and the second end can be rotatably connected to the fourth fulcrum via a rotating shaft structure.

[0267] The first end of the fifth link 805 is rotatably connected to the fifth fulcrum via the seventh link 807. The second end of the fifth link 805 is rotatably connected to the rack 72.

[0268] The fifth link 805 can be rotatably connected to the rack 72 via a rotating shaft structure. When the first pedal 74 drives the rack 72 to move through the linkage mechanism 80, the rack 72 can move together with the fifth link 805 and rotate relative to the fifth link 805, so that the rack 72 drives the second gear 22 to rotate.

[0269] The fifth fulcrum can be located at the support base 50 and / or the top cover 66. The first end of the seventh link 807 can be rotatably connected to the fifth link 805 via a pivot structure, and the second end can be rotatably connected to the fifth fulcrum via a pivot structure.

[0270] The fourth link 804 and the fifth link 805 are arranged in a cross configuration and are rotatably connected at the intersection. The fourth link 804 and the fifth link 805 can be rotatably connected via the third connecting shaft 88.

[0271] Multiple first through holes 804A may be provided on the fourth link 804. The multiple first through holes 804A are arranged sequentially at intervals along the length direction of the fourth link 804.

[0272] Multiple second through holes 805A are provided on the fifth connecting rod 805. The multiple second through holes 805A are arranged sequentially at intervals along the length direction of the fifth connecting rod 805. The diameters of the second through holes 805A and the first through holes 804A are set to allow the third connecting shaft 88 to be inserted.

[0273] The third connecting shaft 88 can be selectively inserted into either the first through hole 804A or either the second through hole 805A. In this way, the transmission ratio of the pedal transmission mechanism 70 can be adjusted.

[0274] When the first pedal lever 74 rotates around the first fulcrum, it can drive the rolling element 84 to rotate around the second connecting shaft 809 and roll laterally on the bearing element 82 through the second connecting rod 802, and drive the third connecting rod 803 to slide laterally, thereby driving the fourth connecting rod 804 to rotate relative to the fifth connecting rod 805, and then pulling the rack 72, so that the rack 72 drives the second gear 22 of the energy storage device 1 to rotate.

[0275] During the rotation of the first pedal lever 74 around the first fulcrum, the acute angle between the first pedal lever 74 and the third link 803 part structure 803B decreases or increases, and the included angle between the second link 802 and the third link 803 part structure 803B decreases or increases.

[0276] As the panel is stepped down, the third pedal 78 is forced to move downward, causing the first pedal 74 and the second pedal 76 to rotate around the first fulcrum and the second fulcrum respectively. This causes the rolling element 84 to rotate around the second connecting shaft 809 and roll laterally on the bearing element 82 via the second connecting rod 802, and causes the third connecting rod 803 to slide laterally. This, in turn, causes the fourth connecting rod 804 to rotate relative to the fifth connecting rod 805, thereby pulling the rack 72, which in turn causes the rack 72 to drive the second pinion 224 of the second gear 22 in the energy storage device 1 to rotate.

[0277] Because a first one-way bearing 21 is provided between the second pinion 224 and the fourth support shaft 25, the second pinion 224 can only drive the second large gear 222 to rotate in one direction through the fourth support shaft 25.

[0278] As the panel is stepped on and moved downwards, the second gear 222 of the second gear 22 can drive the first limiting member 44 to switch between a locked position and an unlocked position via the second transmission assembly. Thus, the pedal transmission mechanism 70 is connected to the first limiting member 44 via the second transmission assembly. During the process of the panel being stepped on and moved downwards, the pedal transmission mechanism 70 can drive the first limiting member 44 to switch between a locked position and an unlocked position via the second transmission assembly.

[0279] During the process of the panel being stepped down, when the second gear 222 of the second gear 22 drives the first limiting member 44 to the locked position via the second transmission assembly, the second gear 222 of the second gear 22 can drive the first gear 12 to rotate in one direction, thereby driving the mainspring to rotate inward and tighten the mainspring. In this way, the step transmission mechanism 70 is connected to the mainspring transmission; during the process of the panel being stepped down, when the second limiting member 44 is in the locked position, the step transmission mechanism 70 can drive the inner ring of the mainspring to rotate and tighten the mainspring; when the second limiting member 44 is in the unlocked position, the outer ring of the mainspring can rotate to release the mainspring's stored energy, thereby driving the seventh gear 64 and the second rotating shaft 54 ​​to rotate via the third transmission assembly, and then driving the generator's motor shaft to rotate to generate electricity.

[0280] Based on the same inventive concept, this embodiment also provides an energy storage and power generation method using a step-on power generation floor. Please refer to... Figure 1 and Figure 5 The energy storage and power generation method of the step-powered power generation floor includes a panel and an energy storage device 1. The energy storage device includes a step transmission assembly 70, a spring, a generator, a second transmission assembly, and a first limiting member 44 that can switch between a locked position and an unlocked position.

[0281] The energy storage and power generation method of this step-based power generation floor includes the following steps:

[0282] Step 1: The first limiting member 44 is in the locking position that prevents the outer coil of the mainspring from rotating. The panel is stepped down and moves down, which drives the inner coil of the mainspring to rotate through the pedal transmission component 70, thereby winding the mainspring.

[0283] Step 2: The panel is stepped on and moved down. Through the step transmission component 70, the first limiting member 44 is moved to the unlock position via the second transmission component, thus unlocking the outer ring of the mainspring.

[0284] Step 3: The outer coil of the mainspring rotates, thereby driving the generator shaft to rotate, causing the generator to generate electricity.

[0285] Step 4: The pedal transmission component 70 drives the first limiting member 44 to move to the locked position through the second transmission component, so as to cycle through the above-mentioned energy storage and power generation method.

[0286] Specifically, please refer to Figure 4 and Figure 5 The energy storage device 1 may include a first gear 12, a second gear 22, a mainspring barrel 13, a first elastic element, a third transmission assembly, and a second rotating shaft 54. The first gear 12 is connected to the inner coil of the mainspring. The mainspring barrel 13 covers the mainspring and is fixed to the outer coil. Multiple teeth 14 are provided on the outer peripheral wall of the mainspring barrel 13, and second tooth grooves are provided between adjacent teeth 14. A second pawl is provided at one end 442 of the first limiting member 44. The second transmission assembly includes a third gear 31, a worm 32, a worm wheel 33, a first rotating shaft 56, and a oscillating element 57. One end of the oscillating element 57 is fixedly connected to the first rotating shaft 56, and the other end is suspended. The third gear 31 is coaxially fixed with the worm 32. The worm 32 meshes with the worm wheel 33 to form a worm gear mechanism. The worm wheel 33 is sleeved on the first rotating shaft 56. The second gear 22 meshes with both the first gear 12 and the third gear 31.

[0287] The above step one may specifically include: the second pawl on the first limiting member 44 located in the locking position is inserted into the second tooth groove to prevent the outer ring of the mainspring from rotating; the panel being stepped down will drive the second gear 22 to rotate through the pedal transmission assembly 70, the second gear 22 drives the first gear 12 to rotate, the first gear 12 drives the inner ring of the mainspring to rotate, thereby winding the mainspring; and the second gear 22 drives the third gear 31 and the worm 32 to rotate, the worm 32 drives the worm wheel 33 and the first rotating shaft 56 to rotate, thereby driving the oscillating member to rotate.

[0288] Step two above may specifically include: the first rotating shaft 56 drives the swing member 57 to rotate until the other end of the swing member 57 abuts against the other end 444 of the first limiting member 44, and drives the first limiting member 44 to rotate until the second pawl disengages from the unlocking position of the second tooth groove, thereby unlocking the outer ring of the mainspring, and the first elastic member elastically deforms.

[0289] Step three above may specifically include: the outer ring of the mainspring rotates, which drives the second rotating shaft 54 ​​to rotate through the third transmission assembly, and the second rotating shaft 54 ​​drives the motor shaft of the generator to rotate, so that the generator generates electricity.

[0290] Step four above may specifically include: the first rotating shaft 56 drives the swing member 57 to rotate until the other end of the swing member 57 is separated from the other end 444 of the first limiting member 44, and the elastic force of the first elastic member is released, thereby driving the first limiting member 44 to rotate to the locked position, so as to cycle the above energy storage and power generation method.

[0291] For more details, please refer to Figure 5 The first rotating shafts 56 of multiple energy storage devices 1 can be connected via a first flexible shaft. A second one-way bearing 58 can be provided between the worm gear 33 and the first rotating shaft 56. The first rotating shafts 56 of multiple energy storage devices 1 can be linked together via the first flexible shaft. When the first rotating shaft 56 of any one energy storage device 1 rotates, it can drive the first rotating shafts 56 of the other energy storage devices 1 to rotate, thereby realizing the sequential release of multiple energy storage devices 1.

[0292] The second shafts 54 of multiple energy storage devices 1 can be linked together via second flexible shafts and connected to the motor shaft of the same generator. As mentioned above, a third one-way bearing 65 may be provided between the second shaft 54 ​​and the seventh gear 64 of the second transmission assembly.

[0293] The other structures of the step-powered power generation floor in the energy storage and power generation method provided in this embodiment can be similarly configured to those of the aforementioned step-powered power generation floor.

[0294] The energy storage device, the step-powered power generation floor, and the energy storage and power generation method provided by this invention can generate electricity using human power, which is green, healthy, energy-saving, and environmentally friendly.

[0295] In this invention, when the panel is stepped on and moved down, the stepping transmission mechanism can drive the first limiting member to switch between a locked position and an unlocked position via the second transmission component. When the first limiting member is in the locked position, the stepping transmission mechanism can drive the first gear to rotate unidirectionally, thereby winding the mainspring to store energy. When the first limiting member is in the unlocked position, the outer ring of the mainspring can rotate to release the stored energy and generate electricity. The energy storage and release of the energy storage device are carried out in a sequential cycle, improving the efficiency of energy storage and power generation, and achieving a high degree of automation.

[0296] By incorporating a foot-operated transmission mechanism and gear assembly, the distance of power movement is reduced, converting the small downward movement of the panel into a larger rotation angle of the second gear, thereby increasing the winding speed of the mainspring and improving energy storage and power generation efficiency. The structure is streamlined and occupies little space. The linkage ratio of the foot-operated transmission mechanism is adjustable, allowing the minimum force required to move the panel downwards to be set according to needs, resulting in a superior user experience.

[0297] The height of the pedal transmission mechanism, the second gear, the first gear, and the second transmission component can be set relatively low, resulting in a smaller overall height of the energy storage device and a smaller footprint in the internal space of the pedal-powered floor.

[0298] The first rotating shafts of multiple energy storage devices are connected by a first flexible shaft, and the first rotating shafts of multiple energy storage devices can be linked together through the first flexible shaft, so as to realize the sequential release of the stored energy of multiple energy storage devices.

[0299] The second shafts of multiple energy storage devices can be linked together via a second flexible shaft and connected to the motor shaft of the same generator, eliminating the need for multiple generators. This design is compact and occupies little space.
