Description

Technical Field

[0001] This invention relates to the field of energy harvesting technology, and in particular to a press-type electromagnetic energy harvesting device and an energy harvesting floor. Background Technology

[0002] With the rapid development of IoT technology, numerous innovative concepts such as smart cities, smart buildings, and smart industries have emerged. Against this backdrop, IoT node devices have been widely used in various monitoring fields. However, these devices primarily rely on municipal power grids or chemical batteries for energy. In the long term, reliance on traditional power sources not only limits the widespread adoption of these devices but also increases maintenance costs, such as the expense of replacing or recharging batteries. To address these challenges, environmental energy harvesting technology has shown great potential for powering IoT devices. Energy harvesting technology can convert mechanical energy from natural phenomena such as human movement, wind, and tides into electrical energy, mainly through various conversion mechanisms such as electrostatics, electromagnetics, piezoelectricity, and triboelectricity.

[0003] Everyday life is filled with a large amount of low-frequency vibration energy. To improve energy conversion efficiency and electrical output under low-frequency vibration, researchers have developed various technologies, including frequency enhancement (FUC) technology. These technologies aim to solve the mismatch between the resonant frequency of vibration energy harvesting devices and the ambient vibration frequency. For example, some studies have used nonlinear energy harvesters to significantly broaden the frequency bandwidth and, in some cases, increase the response amplitude. Nevertheless, most existing energy harvesting devices can only operate within the excitation frequency range of 2-10 Hz. When faced with ultra-low-frequency excitations below 1 Hz, such as when a vehicle runs over someone or someone walks, they exhibit low efficiency due to the mismatch between the resonant frequency and the ambient vibration frequency. This narrow bandwidth makes them unsuitable for low-frequency and nonlinear vibration scenarios. Furthermore, some devices are difficult to modularly expand due to structural design limitations, making them unable to adapt to energy harvesting needs of different scales. Consequently, these harvesters often have low conversion efficiency and low electrical output when dealing with low-frequency vibration energy. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] like Figures 1 to 10 As shown, this application embodiment provides a press-type electromagnetic energy harvesting device 50. The press-type energy harvesting device includes an upper cover 51, a lower cover 52, a magnetic component 53, a coil 54, a pressure plate 55, and an end cap 56. The lower cover 52 is disposed below the upper cover 51. A positioning groove 522 is provided at the top of the lower cover 52, and a positioning rod 511 is provided at the bottom of the upper cover 51. The positioning rod 511 is inserted into the positioning groove 522 to connect the upper cover 51 and the lower cover 52. Both the lower surface of the upper cover 51 and the upper surface of the lower cover 52 are provided with... There is at least one set of coils 54. The lower cover 52 is provided with a first slide groove 521. The coils 54 in the lower cover 52 are located in the first slide groove 521. The magnetic element 53 is located between two opposing coils 54. The magnetic element 53 can slide in the first slide groove 521. That is, by utilizing the principle of electromagnetic induction, the magnetic element 53 generates electrical energy by moving between the coils 54. A first guide structure is provided between the magnetic element 53 and the first slide groove 521. The first guide structure is used to make the movement of the magnetic element 53 in the first slide groove 521 smooth.

[0020] A second sliding groove 551 is provided on the pressure plate 55. The size of the second sliding groove 551 is larger than that of the first sliding groove 521. The lower cover 52 is disposed in the second sliding groove 551 and can slide within the second sliding groove 551. A second guide structure is provided between the lower cover 52 and the pressure plate 55 to ensure smooth movement of the lower cover 52 within the second sliding groove 551. End caps 56 are provided at intervals at the ends of the pressure plate 55. The end caps 56 are connected to the pressure plate 55 by a first spring assembly 80. When the pressure plate 55 is impacted, the pressure plate 55 moves towards the end cap 56 under force. At this time, the first spring assembly 80 is compressed, and the pressure plate 55 moves closer to the end cap 56, while simultaneously driving the magnetic component 53 to move between the coils 54. When the pressure plate 55 is no longer under force, the elastic force of the first spring assembly 80 drives the pressure plate 55 to move away from the end cap 56, and drives the magnetic component 53 to move between the coils 54, that is, the pressure plate 55 returns to its original position.

[0021] In this application, the upper cover 51 is provided with three sets of coils 54, and the lower cover 52 is provided with three sets of coils 54. A first groove 512 is provided on the lower surface of the upper cover 51, with three first grooves 512 arranged side-by-side. The three sets of coils 54 are respectively installed in the three first grooves 512. A second groove 523 is provided on the upper surface of the lower cover 52, i.e., the bottom surface of the first sliding groove 521, with three second grooves 523 arranged side-by-side. The three sets of coils 54 are respectively installed in the three second grooves 523. Of course, in other embodiments, the number of coils 54 can be two, four, or five sets; the number of coils 54 is not limited here.

[0022] In one embodiment, the press-type electromagnetic energy harvesting device 50 further includes a second spring assembly 90 and a stop 100. The stop 100 is disposed within the first slide groove 521 and at one end away from the end cover 56. The stop 100 is connected to the lower cover 52 via the second spring assembly 90. The stop 100 cooperates with the second spring assembly 90 to prevent the magnetic component 53 from impacting and damaging the pressure plate 55 during movement.

[0023] The function of the stop block 100 is to realize the reversal or stop of the moving parts, create conditions for the next stage of movement, and absorb some of the impact energy to protect the structural integrity of the device.

[0024] Specific applications in this invention: Reversing function: When the movement of the magnetic component 53 reaches its limit position, the stop block 100 absorbs kinetic energy through the second spring group 90 and releases it in the opposite direction, so that the magnetic component 53 completes the reversal of direction and passes through the coil 54 again, increasing the number of magnetic flux changes and improving energy conversion efficiency.

[0025] Buffer protection: The magnetic component 53 impacts the stop block 100 to absorb some of the kinetic energy, preventing the magnetic component 53 from directly impacting the lower cover 52 or other rigid structures, thus reducing mechanical wear and energy waste.

[0026] In one embodiment, the press-type electromagnetic energy harvesting device 50 further includes a latch 110 and a third spring assembly 120. The latch 110 is slidably disposed within the first slide groove 521 and connected to the end cap 56 via the third spring assembly 120. The latch 110 functions to lock and release the magnetic component 53. By controlling the timing of energy storage and release of the third spring assembly 120, the energy conversion process becomes more efficient and precise.

[0027] The specific use of the locking mechanism 110 in this invention: Locking function: The card lock 110 locks the magnetic component 53 in the initial state through the path matching structure design (matching of card slot and card bar) to prevent it from being ejected prematurely and releasing kinetic energy.

[0028] Release function: When the external force generated by a vehicle or pedestrian running over the vehicle exceeds the set threshold, the lock 110 will trigger unlocking, releasing the elastic potential energy of the third spring group 120 and driving the magnetic component 53 to move.

[0029] Precise control: The presence of the locking mechanism 110 ensures that the release of the third spring assembly 120 occurs at the optimal time, maximizing the movement of the magnetic component 53 and thereby improving the efficiency of magnetic flux change.

[0030] The locking function of the card lock 110 relies on the following design: 1. Mechanical engagement: The engagement between the card slot and the card strip is achieved through geometric design to form a mechanical interlock. When the external force is insufficient to overcome the interlocking force, the card lock 110 remains locked.

[0031] 2. Unidirectional motion design: The 110 latch allows unidirectional movement during compression but not reverse rebound. This unidirectional design ensures that energy is not wasted when release is not triggered.

[0032] 3. Trigger optimization: The trigger threshold of the 110 card lock is precisely designed to ensure that it will only unlock when external force reaches or exceeds the set value, thus preventing accidental release.

[0033] In one embodiment, the press-type electromagnetic energy harvesting device 50 further includes a limiting block 70. A mounting groove with a size and shape that matches the limiting block 70 is provided at one end of the pressure plate 55 near the end cover 56. The limiting block 70 is installed in the mounting groove and is used to limit the pressure plate 55 from abutting against the end cover 56.

[0034] Working mechanism of limit block 70: 1. Structural Function: The limiting block 70 has a certain elastic or mechanical deformation capacity; when one end is compressed, the other end will contract. This design allows the limiting block 70 to deform under external force and plays a control role in the system during the deformation process.

[0035] 2. Work process: Initial state: When no external force is applied, the limit block 70 maintains its initial shape, ensuring that the third spring group 120 and the latch 110 are in the locked state.

[0036] Force state: When an external force (such as a vehicle running over it or a pedestrian walking on it) is applied to one end of the limiting block 70, that end is compressed and the other end of the limiting block 70 contracts.

[0037] Triggering effect: As the limit block 70 is pressed to the critical value, its deformation causes its contraction end to be unable to continue to hold the magnetic component 53. Therefore, the magnetic component 53 is ejected by the third spring group 120, releasing the elastic potential energy of the third spring group 120.

[0038] In one embodiment, the first guide structure includes a first guide ball 57 and a first guide groove 524. The first guide groove 524 is disposed on the inner side of the lower cover 52, that is, the first guide groove 524 is disposed on the side wall of the first slide groove 521. The first guide ball 57 is disposed on the magnetic component 53, and a ball groove is provided on the magnetic component 53. The first guide ball 57 is disposed in the ball groove. When the magnetic component 53 moves in the first slide groove 521, the first guide ball 57 rolls in the first guide groove 524. Correspondingly, the second guide structure includes a second guide ball 58 and a second guide groove 525. The second guide groove 525 is disposed on the outer side of the lower cover 52, and the second guide ball 58 is disposed on the pressure plate 55. A ball groove is provided on the inner side wall of the second slide groove 551, and the second guide ball 58 is disposed in the ball groove. When the lower cover 52 slides in the second slide groove 551, the second guide ball 58 rolls in the second guide groove 525. The number of the first guide ball 57 and the second guide ball 58 can be set according to actual needs. The first guide ball 57 and the second guide ball 58 are essentially the same. The first guide structure and the second guide structure of this application can make the movement of the magnetic component 53 and the lower cover 52 easier and more stable.

[0039] Specifically, the magnetic component 53 includes a magnet 531 and a sliding frame 532. The sliding frame 532 includes a main body 5321 and a support ear 5322. The main body 5321 is disposed in the first sliding groove 521, and the support ear 5322 is mounted above the knee. The limiting block 70 can also block the support ear 5322 to limit the stroke of the magnetic component 53. The magnet 531 is a magnet, and three magnets 531 are disposed in the main body 5321. The number of magnets 531 can be adjusted according to needs. A ball groove is provided on the outer wall of the main body 5321, and a first guide ball 57 is disposed on the ball groove.

[0040] This application provides an energy harvesting floor based on the above principle. The energy harvesting floor includes a top shell 10, a bottom shell 20, a sliding member 30, a fourth spring assembly 40, and a press-type electromagnetic energy harvesting device 50. A push block 11 is provided on the bottom surface of the top shell 10, and the push block 11 is perpendicular to the top shell 10. The bottom shell 20 is located below the top shell 10. The sliding member 30 is located on the bottom shell 20 and below the push block 11. The bottom shell 20 and the top shell 10 are connected by the fourth spring assembly 40. The press-type electromagnetic energy harvesting device 50 is located on the bottom shell 20. When a person walks on the energy harvesting floor, their foot applies force to the top shell 10, compressing the fourth spring assembly 40. The downward pressure of the push block 11 of the shell 10 can push the slider 30 to move laterally. The slider 30 squeezes the pressure plate 55 laterally, causing the pressure plate 55 to move and drive the magnet 531 to move between the coils 54. The first spring group 80 is compressed. When a person lifts their leg, the elastic force of the fourth spring group 40 causes the top shell 10 to return to its original position. The push block 11 moves upward, and the elastic force of the first spring group 80 causes the pressure plate 55 to return to its original position. Correspondingly, the pressure plate 55 also pushes the slider 30 to return to its original position. The slider 30 returns to below the push block 11. Thus, the movement of a person on the floor causes the magnet 531 to reciprocate between the coils 54, thereby continuously generating electrical energy.

[0041] An external force acts on the top shell 10, causing it and the pusher block 11 to descend together. This pushes the slider 30 on the third slide groove 61 to move to both sides, thereby compressing the pressure plate 55. This compressive force acts on the end of the limiting block 70 facing the bottom shell 20, causing it to deform. This deformation of the top contraction end causes the locking mechanism of the magnetic component 53 to fail, thus preventing the magnetic component 53 from maintaining its original position.

[0042] To limit the movement of the slider 30, a guide seat 60 is provided on the bottom shell 20. The guide seat 60 is provided with a third slide groove 61. The slider 30 is disposed in the third slide groove 61. The slider 30 is specifically a trapezoidal slider. A retaining strip 21 is provided on the bottom shell 20, and a retaining groove 62 is provided on the guide seat 60. The retaining strip 21 is inserted into the retaining groove 62. In this way, the guide seat 60 will not shift its position when subjected to force.

[0043] In one embodiment, a mounting groove 22 is also provided on the bottom shell 20, and a circuit board is installed in the mounting groove 22. The mounting groove 22 is located at the center of the bottom shell 20. In this application, four push-to-open electromagnetic energy harvesting devices 50 are provided and distributed around the mounting groove 22. Of course, the number of push-to-open electromagnetic energy harvesting devices 50 can be adjusted according to the size of the bottom shell 20, and is not limited here.

[0044] The function of the circuit board here: 1. Core components of energy management: The circuit board is the core of energy management in the entire device, used to convert the unstable electrical energy generated by the push-to-react electromagnetic energy harvesting device into a stable and usable power output to meet the needs of the electrical equipment.

[0045] 2. Energy rectification and voltage regulation: The electrical energy collected by the press-type electromagnetic energy harvesting device is alternating current or pulsating direct current, which is converted into pure direct current by the circuit board through a rectifier module.

[0046] The voltage regulator circuit adjusts the output voltage to ensure that the voltage received by the electrical equipment is stable within the safe operating range, thus avoiding the impact or damage to the equipment due to voltage fluctuations.

[0047] 3. Energy storage and allocation: The circuit board connects to energy storage devices (such as supercapacitors or rechargeable batteries) to collect and accumulate multiple short-term energy sources into sustainable electrical energy output, thereby enhancing the system's energy efficiency.

[0048] When electricity demand fluctuates, energy is intelligently allocated through energy distribution circuits to meet the dynamic needs of the load.

[0049] 4. Output interface compatibility with electrical equipment: The circuit board includes output interfaces (such as USB, voltage terminals, etc.) for direct connection to electrical devices.

[0050] The adapter module adjusts the output voltage and current according to the device requirements (such as 3.3V, 5V or 12V) to improve system compatibility.

[0051] 5. Energy harvesting efficiency monitoring and optimization: An integrated energy monitoring module detects and collects electrical energy, voltage, and current in real time, providing feedback information on energy conversion efficiency.

[0052] In a multi-module energy harvesting array, the circuit board coordinates the output of each module to avoid energy waste or conflict.

[0053] 6. Protection functions: The circuit board uses overvoltage, overcurrent, and short-circuit protection circuits to prevent damage to electrical equipment or internal components due to abnormal conditions.

[0054] To prevent the device from outputting unstable power when energy is insufficient, thus ensuring the overall safety of the system.

[0055] In this application, the first spring group 80, the second spring group 90, the third spring group 120 and the fourth spring group 40 are substantially the same, each consisting of multiple springs.

[0056] In this invention, when a vehicle or pedestrian runs over the energy harvesting floor, the third spring assembly 120 is compressed, storing its kinetic energy as elastic potential energy. Upon release, this compresses the magnetic component 53, causing it to complete a planar displacement between coils 54. Subsequently, the magnetic component 53 reverses its direction of motion by striking the stop block 100, traversing the coils 54 again. During this process, the magnetic component 53 generates two significant changes in magnetic flux within the same coil 54 (bidirectional traversal). According to Faraday's law of electromagnetic induction, these two changes in magnetic flux generate a larger induced electromotive force, thereby significantly improving energy conversion efficiency. Furthermore, this invention is optimized for ultra-low frequency vibrations (below 1Hz) generated by vehicle running over or pedestrian walking. Combined with the locking structure 110 and multiple spring assemblies, it ensures full utilization of ultra-low frequency kinetic energy during magnet release. Compared to existing technologies, this invention significantly improves energy harvesting efficiency under low-frequency vibrations.

[0057] The energy harvesting floor of the present invention has the following advantages: 1. It can convert the kinetic energy generated by vehicles running over people or people walking into the elastic potential energy of springs, thus playing a role in kinetic and potential energy conversion and avoiding energy waste.

[0058] 2. It consists of 50 individual press-type electromagnetic energy harvesting units connected together, which are highly scalable and can be used on a large scale. It is suitable for various scenarios of collecting kinetic energy generated by vehicles running over or people walking.

[0059] 3. Due to the adoption of a self-locking structure and durable materials, the maintenance cost is very low, which reduces the overall operating cost in the long run.

[0060] 4. It can collect energy at frequencies below 1Hz, achieving the goal of collecting ultra-low frequency vibration energy.

[0061] 5. It has a large power generation capacity and high energy density, which can effectively power IoT devices.

[0062] 6. It is made of high-strength materials, ensuring that it can withstand repeated pressure for a long time without being easily damaged, thus extending its service life.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
