Description

Technical Field

[0001] The invention belongs to the technical field of composite power generation, and relates to a mechanical power generation device and a power generation shoe. Background Art

[0002] In recent years, the technology of harvesting human motion energy has made significant progress. Among them, the technology of converting the mechanical energy generated by walking into electrical energy through micro-power generation devices and storing it is particularly eye-catching. With its unique convenience, sustainability, environmental protection and the advantages of not requiring an external power supply, this technology provides a new way to solve the energy supply problem of portable devices. It is expected to become a long-lasting and stable source of power for portable electronic products such as smartphones and wearable devices, contributing to the realization of sustainable development goals, while reducing dependence on traditional energy and reducing carbon emissions. It is especially suitable for military and rescue, outdoor sports and adventure fields, such as individual combat equipment, disaster relief, outdoor sports and adventure scenes.

[0003] At present, the methods of converting mechanical energy into electrical energy can be mainly divided into: piezoelectric material power generation, friction power generation, electromagnetic induction power generation and power generation based on the principle of generator according to different principles. However, these methods all face their own challenges in practical applications. Due to the large resistance of piezoelectric materials, the electrical energy converted from mechanical energy has the problem of high voltage but extremely low current, which cannot realize the storage of electrical energy. In addition, piezoelectric materials have strict requirements on environmental conditions and require specific pressure and temperature conditions to work effectively. Friction power generation materials are scarce in the market, and the energy conversion efficiency is low. At the same time, their power generation efficiency is easily affected by various external environmental factors and has poor stability. Although the principle of electromagnetic induction power generation technology is simple, the energy generated is relatively limited, which is difficult to meet the needs of higher power equipment, and the equipment structure is relatively large and complex. In contrast, based on the principle of micro-generators, the mechanical energy generated during walking is converted into electrical energy through a mechanical structure. This method has the advantages of economical and easy-to-obtain devices and relatively simple principles.

[0004] However, in actual applications, the power generation device based on the principle of micro-generators also exposed some problems. First, there is energy loss in the transmission process of the mechanical structure, resulting in low power generation efficiency; second, the mechanical structure is relatively large and complex, which not only increases the manufacturing cost and difficulty, but also is not conducive to the application and promotion in actual products; in addition, the power generation device located inside the sole is equipped with a USB interface to achieve power output, which is inconvenient to use and limits its promotion and application. Summary of the invention

[0009] Preferably, the wireless charging transmitting unit includes a first wireless charging transmitting component and a second wireless charging transmitting component; the first wireless charging transmitting component and the second wireless charging transmitting component are electrically connected to the first power generation part and the second power generation part respectively.

[0010] Preferably, the mechanical power generation device further comprises a base, a mounting shaft is provided on the base, the first gear is vertically arranged on the mounting shaft, and the first gear can rotate along the circumferential direction of the mounting shaft.

[0011] Preferably, the mechanical power generation unit further comprises a bottom plate, and the base is fixedly arranged on the bottom plate; a pedal is also arranged on the first gear; A first return spring and a second return spring are sleeved on the mounting shaft.

[0012] Preferably, the speed increasing ratio between the first gear and the speed increasing gear set is 3-5.

[0013] Preferably, the speed increasing ratio between the speed increasing gear set and the planetary speed regulator is 1-2.

[0014] Preferably, both the wireless charging transmitting unit and the wireless charging receiving unit are provided with a filter component.

[0015] A power generating shoe comprises the above-mentioned mechanical power generating device, wherein the mechanical power generating device is arranged inside the sole.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention discloses a mechanical power generation device, the core components of which include a mechanical power generation unit and an electric energy storage unit. The mechanical power generation unit includes a first gear, a speed-increasing gear set and a planetary speed regulator which are arranged in meshing sequence. The first gear serves as the initial power input end of the entire mechanical power generation system and transmits energy through rotational motion. The speed-increasing gear set is designed to increase the rotation speed, thereby increasing the input power of subsequent power generation components. The speed amplification can be achieved by meshing gears of different sizes with each other, thereby improving the power generation efficiency. While ensuring that the power generation components obtain sufficient power input, the mechanical losses in the transmission process, such as friction losses and energy dissipation, can be minimized. The planetary speed regulator is a complex gear transmission device, which can not only transmit power, but also change the output speed and torque by adjusting the relative positions of the planetary gears, the sun gear and the ring gear. In the present invention, it is mainly used to adjust the input speed of the power generation component to ensure that the power generation process is stable and efficient. At the same time, the system can adjust the output speed and torque according to actual needs, thereby optimizing the working state of the power generation component and reducing energy loss caused by speed mismatch or load fluctuation; the power generation component is a key component for converting mechanical energy into electrical energy. It receives power from the planetary speed regulator and converts it into electrical energy. The wireless charging transmitting unit is electrically connected to the power generation component and is responsible for transmitting the generated electrical energy to the energy storage unit in a wireless manner. The wireless charging transmitting unit and the wireless charging receiving unit use efficient wireless charging technology to reduce energy loss during transmission and improve charging efficiency. In addition, the distance monitoring component can monitor the charging distance in real time to ensure that the wireless charging system works within the optimal distance range and avoid energy loss caused by too far or too close a distance. The power generation device has high transmission efficiency and low energy loss. At the same time, it uses wireless transmission to transmit the energy to the energy storage unit, which is convenient for the use of electrical equipment.

[0017] Furthermore, another inventive point of the present invention is that the power generation component includes a first power generation part and a second power generation part; the first power generation part and the second power generation part are respectively connected to the two output ends of the planetary speed regulator. First, the planetary speed regulator can output power in two directions at the same time through its gear transmission mechanism. This design enables the first power generation part and the second power generation part to work at the same time, thereby improving the power generation efficiency of the entire power generation component; in addition, the design of the dual power generation parts also provides convenience for fault detection and maintenance. During normal operation, the output conditions of the two power generation parts can be compared, and potential problems can be discovered and dealt with in time; at the same time, since the two power generation parts work independently, they can be independently optimized according to their respective characteristics, such as adjusting the number of coil turns, optimizing the winding method, etc., to further improve the energy conversion efficiency.

[0018] Furthermore, another inventive point of the present invention is that the first power generation unit includes a plurality of first generators arranged in parallel, and the second power generation unit includes a plurality of second generators arranged in parallel. Firstly, by modularizing the generator design, that is, the first power generation unit and the second power generation unit each include a plurality of parallel generators, it is easier to expand or reduce according to actual needs. This flexibility enables the system to adjust the power generation capacity according to load changes, thereby improving the overall power generation efficiency. In addition, in a parallel setting, each generator can share the load together, avoiding the risk of a single generator being overloaded and having its efficiency reduced or damaged. Load balancing helps keep each generator in optimal working condition, thereby improving the power generation efficiency of the entire power generation unit. At the same time, the parallel setting can effectively increase the total current and improve the power generation efficiency; moreover, multiple generators set in parallel provide redundancy for the system. When one of the generators fails, the other generators can still continue to work to ensure continuous power supply to the system. This redundant design greatly improves the reliability and stability of the system. Since the generators are set in parallel, when a generator fails, it can be easily isolated from the system for repair or replacement without affecting the normal operation of other generators, thus achieving fault isolation. This fault isolation mechanism helps to reduce system downtime, improve system availability, and make daily maintenance more convenient, more flexible to use, and easier to expand.

[0019] Furthermore, another inventive point of the present invention is that the wireless charging transmitting unit includes a first wireless charging transmitting component and a second wireless charging transmitting component; the first wireless charging transmitting component and the second wireless charging transmitting component are electrically connected to the first power generation part and the second power generation part respectively. First, by splitting the wireless charging transmitting unit into two independent transmitting components and connecting them to two independent parts of the power generation part, a modular design of the system is realized. This design enables the wireless charging system to be flexibly configured and expanded according to actual needs. Each wireless charging transmitting component can be independently controlled, and the output power, frequency and other parameters can be adjusted separately to adapt to different devices or different charging needs. In addition, when one of the wireless charging transmitting components fails, the other component can still work normally and provide wireless charging services for the device. This redundant design enhances the stability and reliability of the system and reduces the risk of system downtime caused by a single point of failure. Through the collaborative work of the two wireless charging transmitting components, a balanced load distribution can be achieved, which helps to reduce the working pressure of each component, extend its service life, and reduce the risk of performance degradation or damage caused by overload.

[0020] Furthermore, another inventive point of the present invention is that the mechanical power generation device also includes a base, a mounting shaft is provided on the base, the first gear is vertically arranged on the mounting shaft, and the first gear can rotate along the circumference of the mounting shaft. First, the base provides a stable mounting platform for the first gear, which ensures that the device can remain stable during operation and reduces performance degradation or damage caused by vibration or shaking; the mounting shaft is arranged on the base to support and fix the first gear. This design enables the first gear to rotate circumferentially around the mounting shaft, that is, to achieve its rotational motion. The existence of the mounting shaft not only provides the first gear with an axis of rotation, but also ensures the stability and accuracy of the rotation. Secondly, the first gear is vertically arranged on the mounting shaft. The vertical arrangement can make the entire device more compact in the vertical direction, reduce the floor space, and improve the space utilization rate. This is particularly important for occasions where the mechanical power generation device needs to be installed in a limited space. In addition, when the first gear is meshed with other gears or transmission components, the vertical arrangement can make the transmission path more direct and efficient, reducing the energy loss and transmission efficiency reduction caused by the long or complex transmission path.

[0021] Furthermore, another inventive point of the present invention is that the mechanical power generation unit also includes a bottom plate, and the base is fixedly arranged on the bottom plate; a pedal is also arranged on the first gear; a first return spring and a second return spring are sleeved on the mounting shaft, and one end of the first return spring and the second return spring are both in contact with the pedal, and the other end is both in contact with the bottom plate. Here, the bottom plate serves as a fixed platform for the base, which enhances the stability of the entire mechanical power generation unit. It provides a solid foundation, so that the base and the components installed on it can work stably, reducing displacement or damage caused by vibration or external force. The pedal is arranged on the first gear so that the user can directly drive the first gear to rotate by stepping on it, thereby converting it into electrical energy. This design improves the human-computer interaction of the mechanical power generation unit and makes the power generation process more convenient. The first return spring and the second return spring are arranged between the pedal and the bottom plate to play the role of energy recovery and storage. When the user steps on the pedal, the two free ends of the spring rotate along the circumference of the spring and drive the first gear to rotate to realize the power generation process. When the user releases the pedal, the spring releases energy and helps the pedal return to its initial position. This design not only improves the energy utilization efficiency, but also enables the pedal to automatically reset, reducing the user's operating burden. At the same time, the presence of the return spring also plays a buffering role, reducing the impact of the pedal on the first gear and the mounting shaft during the stepping and releasing process, which helps to extend the service life of the components and reduce failures and maintenance costs caused by impact and wear.

[0022] Furthermore, another inventive point of the present invention is that the speed ratio of the first gear to the speed-increasing gear set is 3 to 5. First, the design of the speed-increasing gear set enables the speed-increasing gear set to effectively convert the lower speed of the first gear into a higher speed. This conversion helps to optimize the speed matching in the subsequent power generation process, so that the generator can operate in a more efficient speed range, thereby improving the power generation efficiency. By setting a reasonable speed-increasing ratio, the energy loss in the speed conversion process can be reduced. A lower speed-increasing ratio means less mechanical friction and energy dissipation, thereby improving the energy conversion efficiency of the entire power generation system. In addition, a reasonable speed-increasing ratio helps to reduce vibration and noise in the gear transmission process. When the speed-increasing ratio is too large, it may cause unstable meshing between gears, resulting in greater vibration and noise, while an appropriate speed-increasing ratio can maintain the stability of the gear transmission and reduce unnecessary vibration and noise; at the same time, the design of the speed-increasing ratio is also related to the accuracy of the gear transmission. An appropriate speed-increasing ratio can ensure that the meshing between gears is tighter and more accurate, reduce transmission errors and deviations, and thus improve the stability and reliability of the entire power generation system.

[0023] Furthermore, another inventive point of the present invention is that the speed ratio between the speed-increasing gear set and the planetary speed regulator is 1 to 2. First, a smaller speed ratio means that in the process of power transmission from the speed-increasing gear set to the planetary speed regulator, the speed change is relatively gentle, which reduces the impact and vibration caused by the sudden change of speed and improves the smoothness of the entire transmission system. The planetary speed regulator usually has a wider speed regulation range and higher speed regulation accuracy; in addition, a smaller speed ratio enables the planetary speed regulator to control the output speed more accurately to meet different working requirements. At the same time, a smaller speed ratio means that in the transmission link between the speed-increasing gear set and the planetary speed regulator, the energy loss is relatively small, thereby improving the efficiency of the entire transmission system. At the same time, by adjusting the speed ratio, the planetary speed regulator can work in a more optimized speed range, which helps to reduce internal friction, wear and heat generation, and further improve the transmission efficiency.

[0024] Furthermore, another inventive point of the present invention is that both the wireless charging transmitting unit and the wireless charging receiving unit are provided with a filtering component, which can effectively filter out the harmonics and stray signals generated during the wireless charging process, reduce the energy loss of these useless signals during the transmission process, thereby improving the overall charging efficiency, and the filtering component can also help stabilize the transmission frequency between the transmitting unit and the receiving unit, ensure that energy is transmitted at the optimal frequency, and reduce energy waste caused by frequency offset; in addition, the filtering component can effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI), prevent these interference signals from causing adverse effects on the internal circuits and peripheral equipment of the wireless charging system, and improve the overall stability of the system. At the same time, the filtering component can also protect the circuit safety of the wireless charging system to a certain extent, and prevent damage to circuit components due to abnormal conditions such as overvoltage and overcurrent.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figures 1 to 4 As shown, the present invention discloses a mechanical power generation device, including a mechanical power generation unit 1 and an energy storage unit 2; the mechanical power generation unit 1 includes a first gear 11, a speed increasing gear set 12 and a planetary speed regulator 13 which are arranged in sequence in meshing relationship; the output end of the planetary speed regulator 13 is connected to a power generation component 14, and a wireless charging transmitting unit 15 for transmitting an electrical signal is electrically connected to the power generation component 14; the energy storage unit 2 includes an electrically connected wireless charging receiving unit 21, an energy storage component 22 and a distance monitoring component 23; the wireless charging receiving unit 21 is used to receive an electrical signal.

[0035] In addition, if Figure 2 As shown, the wireless charging transmitting unit 15 includes a first wireless charging transmitting component 151, a second wireless charging transmitting component 152, a transmitter control circuit board 153 and a wireless charging transmitter antenna 154; the first wireless charging transmitting component 151 and the second wireless charging transmitting component 152 are both electrically connected to the transmitter control circuit board 153, and the transmitter control circuit board 153 is electrically connected to the wireless charging transmitter antenna 154.

[0036] The wireless charging receiving unit 21 includes a wireless charging receiver antenna 211 and a wireless receiver circuit board 212. In addition, the wireless charging transmitting unit 15 and the wireless charging receiving unit 21 are both welded with a filter component, which processes the signal by changing the spectrum characteristics of the signal, that is, to achieve stable transmission of electromagnetic waves in a specific frequency band, and ensure stable transmission of electric energy during wireless charging. In this process, long-distance and efficient electrical transmission is achieved through electromagnetic induction. The filter component here is generally a linear two-port device composed of components such as resistors, capacitors, and inductors. The filter component selects the frequency of the input signal through a specific circuit structure inside, thereby filtering and purifying the signal. These components form a circuit network with a specific frequency response through a specific connection method. When the input signal passes through these circuit networks, signal components of different frequencies will be attenuated or amplified to varying degrees, thereby filtering the signal.

[0037] In order to improve the transmission efficiency, the present invention introduces a speed-increasing gear, which can change the speed and torque of the driving shaft so that the driven shaft can obtain a higher speed or a greater torque. The speed-increasing gear system is a gear system in which the angular velocity of the driven wheel at the end is greater than the angular velocity of the driving wheel at the beginning. The speed increase and torque regulation of the speed-increasing gear system depends on the torque-increasing ratio, that is, the ratio of the number of teeth of the driving gear input gear to the number of teeth of the driven gear output gear. Specifically, when the number of teeth of the driving gear is less than that of the driven gear, the speed of the driven gear will be higher than that of the driving gear, thereby achieving a speed-increasing effect. For example, if the driving gear has 20 teeth and the driven gear has 80 teeth, then the torque-increasing ratio is 4:1. In this case, when the driving gear rotates with a certain torque, the torque obtained by the driven gear will be 4 times that of the driving gear torque, thereby achieving a speed increase of the driven gear.

[0038] In the present invention, Figure 3 As shown, the speed-increasing gear set 12 includes a rotating shaft 121, on which a driving wheel 122 and a driven wheel 123 are provided. In order to increase the speed, the number of teeth of the driven wheel 123 is greater than the number of teeth of the driving wheel 122. The gear ratio of the driven wheel 123 to the driving wheel 122 is 4:1, that is, the speed-increasing ratio is 4:1. Here, the driving wheel 122 can be a speed-increasing pinion, and the driven wheel 123 can be a one-way bearing external gear.

[0039] One-way gears allow the gears to rotate in one direction. The working principle of one-way gears is based on the mechanism of engagement and disengagement in the direction of the input torque, that is, when the input shaft rotates in a certain direction, the rollers will be pressed into the wedge-shaped space between the inner gear ring and the outer gear ring, thereby allowing the outer gear ring to drive the inner gear ring to rotate together, thereby realizing the transmission of power. However, when the input shaft rotates in the opposite direction, the rollers will be pushed away from the wedge-shaped space, and the contact between the inner gear ring and the outer gear ring will be released, so that the power cannot be transmitted, thereby achieving the purpose of one-way transmission. In the present invention, a driven wheel 123 with a one-way bearing is used to realize the one-way transmission of mechanical force, which effectively ensures the stable operation of the generator.

[0040] In the present invention, the driving wheel 122 and the driven wheel 123 are both arranged on the rotating shaft 121, and the rotating shaft 121 can be a transmission shaft. The planetary speed regulator 13 is provided with an input gear 131, and the driving wheel 122 is meshed with the first gear 11, and the driven wheel 123 is meshed with the input gear 131 on the planetary speed regulator 13. The torque and speed of the driving wheel 122 are transmitted to the input gear 131 on the planetary speed regulator 13 through the rotating shaft 121 and the driven wheel 123. The driven wheel 123 can rotate freely in one direction and be locked in the other direction, so as to realize the one-way transmission of energy. Compared with the traditional ratchet and pawl structure with large volume and complex structure, the whole electric energy collection device is smaller in volume and simpler in structure.

[0041] like Figure 5 As shown, the outer ring of the driven wheel 123 is provided with two raised arc surfaces 1231, and the driven wheel 123 is processed by precision wire cutting to match the arc surface to transmit power, the driven wheel 123 is sleeved on the rotating shaft 121, and the rotating shaft 121 is set on the fixed seat 7, and the driving wheel 122 is tightly matched with the rotating shaft 121 to transmit power, and the driven wheel 123 has no inner ring, and the rotating shaft 121 directly contacts the roller of the bearing to realize one-way power transmission and power generation. The higher the speed of the input end of the power generation component 14, the greater the output voltage, the generator has constant power output, and the output voltage is high and the current is small.

[0042] In addition, if Figures 3-5 As shown, the mechanical power generation device further includes a base 3 , on which a mounting shaft 31 is disposed, and the first gear 11 is vertically disposed on the mounting shaft 31 , and the first gear 11 can rotate along the circumferential direction of the mounting shaft 31 .

[0043] The mechanical power generation unit 1 also includes a bottom plate 4, and the base 3 and the fixing seat 7 are fixedly arranged on the bottom plate 4; the first gear 11 is also provided with a pedal 111; the mounting shaft 31 is sleeved with a first return spring 32 and a second return spring 33, one end of the first return spring 32 and the second return spring 33 are both in contact with the pedal 111, and the other end is in contact with the bottom plate 4. That is, the two free ends of the first return spring 32 and the second return spring 33 have a certain angle, and the two free ends of the spring can rotate along the circumference of the spring to achieve the circumferential approach or separation of the two free ends of the spring to achieve the transmission of mechanical force. The speed increasing gear set 12 is fixed to the bottom plate 4 by micro high-strength screws.

[0044] In a preferred embodiment, the first gear 11 can be a sector gear. Furthermore, the number of teeth of the first gear 11 can be 45, and the number of teeth of the driving wheel 122 can be 15. The first gear 11 rotates a small angle, which can make the driving wheel 122 rotate a large angle, then the first-stage speed increase ratio i1=45 / 15=3, the driving wheel 122 and the driven wheel 123 are on the same shaft and are firmly connected to the shaft, and the torque and speed of the driving wheel 122 are transmitted to the input gear 131 on the planetary governor 13 through the rotating shaft 121 and the driven wheel 123. Assuming that the number of teeth of the driven wheel 123 is 45 and the number of teeth of the input gear 131 is 30, then the second-stage speed increase ratio i2=45 / 30=1.5. The planetary governor 13 adopts multi-stage micro-planetary transmission to achieve a very high speed ratio. Assuming that the third-stage speed increase ratio i3=350, the output end of the planetary governor 13 outputs from the dual-axis on both sides, which can simultaneously drive the power generation component 14 to achieve high-efficiency power generation. When the device is used, the rotation of the first gear 11 can be realized by rotating the pedal 111, and then the first gear 11 drives the speed-increasing gear set 12 and the planetary speed regulator 13 to rotate, and finally the mechanical energy is converted into electrical energy through the power generation component 14, and transmitted and stored in the power storage component 22 through the wireless charging transmitting unit 15 and the wireless charging receiving unit 21. According to the speed increase ratio in this embodiment, assuming that the pedal 111 rotates once, the angle of rotation of the first gear 11 is about 21°, then after three levels of speed increase, the angle input to the generator end is 21*i1*i2*i3=33075°, and the speed of the generator input shaft is: 33075 / 360=91.875 laps, and the entire power generation device achieves high-efficiency power generation. The above-mentioned driving wheel 122 and driven wheel 123 are used in conjunction with the planetary speed regulator 13 to achieve a speed increase ratio of up to 1575:1 for the entire speed increase device, and the speed input to the generator end reaches the high-speed generator standard. The entire speed increase unit is small in size, simple in structure, and achieves high-efficiency speed increase.

[0045] In the present invention, the speed increasing ratio between the first gear 11 and the speed increasing gear set 12 is 3-5, preferably 4, and the speed increasing ratio between the speed increasing gear set 12 and the planetary speed regulator 13 is 1-2, preferably 1.5.

[0046] like Figure 6 As shown, the wireless charging transmitting unit 15 includes a first wireless charging transmitting component 151 and a second wireless charging transmitting component 152; the first wireless charging transmitting component 151 and the second wireless charging transmitting component 152 are electrically connected to the first power generation part 141 and the second power generation part 142 respectively. In order to further improve the efficiency of power generation, the power generation component 14 includes a first power generation part 141 and a second power generation part 142; the first power generation part 141 and the second power generation part 142 are respectively connected to the two output ends of the planetary speed regulator 13. The first power generation part 141 includes a plurality of first generators 1411 connected in parallel, and the second power generation part 142 includes a plurality of second generators 1421 connected in parallel.

[0047] Preferably, the first power generation unit 141 may include three first generators 1411, which may be three-phase AC synchronous micro-generators and may realize simultaneous high-speed rotation and power generation through a plurality of first synchronous belts 5. The electricity generated by the first power generation unit 141 is transmitted to the first wireless charging transmitting component 151 through a low-resistance flexible wire to realize wireless charging.

[0048] Similarly, the second power generation unit 142 may also include three second generators 1421. The second generator 1421 may also be a three-phase AC synchronous micro generator, and realize simultaneous high-speed rotation and power generation through a plurality of second synchronous belts 6. The electricity generated by the second power generation unit 142 is also transmitted to the second wireless charging transmitting component 152 through a low-resistance flexible line to realize wireless charging.

[0049] At the same time, if Figure 7-8 As shown, the present invention further discloses a power-generating shoe, comprising a shoe body 8 and the mechanical power generation device of the present invention, and the mechanical power generation unit 1 is arranged in the sole of the shoe body 8 .

[0050] The power-generating shoes of the present invention realize the function of converting mechanical energy into electrical energy and storing it during walking by combining with a mechanical power generation device.

[0051] First, when the user walks in the power-generating shoes, each stepping action will drive the mechanical power generation unit 1 built into the sole to start working. Specifically, the pressure of the foot is transmitted to the first gear 11 through the sole structure, and the first gear 11 starts to rotate as the initial power source. As the first gear 11 rotates, it meshes in turn and drives the speed-increasing gear set 12 to work. The speed-increasing gear set 12 converts the low-speed, high-torque power from the first gear 11 into high-speed, low-torque power through the meshing of multiple gears to improve the power generation efficiency. Subsequently, this high-speed rotating power is transmitted to the planetary governor 13. The planetary governor 13 finely adjusts the rotation speed through its complex planetary gear system to ensure that the power generation component 14 can operate at the optimal speed, thereby improving the stability and efficiency of power generation.

[0052] The power regulated by the planetary speed regulator 13 finally drives the power generation component 14 to generate electricity. The power generation component 14 can convert mechanical energy into electrical energy, and the generated electrical energy is then supplied to the wireless charging transmitter unit 15 through an electrical connection. The wireless charging transmitter unit 15 uses the principle of electromagnetic induction to transmit the electrical energy wirelessly.

[0053] Corresponding to the wireless charging transmitting unit 15 in the mechanical power generation unit 1, the wireless charging receiving unit 21 in the power storage unit 2 can be carried with you and is used to receive power from the transmitting unit. Once the power is received, the wireless charging receiving unit 21 will transfer it to the power storage component 22. The power storage component 22 can be a storage device such as a rechargeable battery or a supercapacitor, which is used to store the converted power.

[0054] In order to ensure the efficiency and safety of the wireless charging process, the energy storage unit 2 further includes a distance monitoring component 23, which optimizes the transmission efficiency and prevents overheating or energy loss by measuring the distance between the wireless charging transmitting unit 15 and the receiving unit 21.

[0055] The electric energy stored in the electric energy storage component 22 can be used for a variety of purposes, such as powering LED lights, sensors or other low-power electronic devices inside the shoes, or for external devices such as charging smart phones through a specific output interface. This self-sufficient energy supply method is not only environmentally friendly and energy-saving, but also improves the intelligence level of the shoes and the user experience. In summary, the power-generating shoes realize the function of converting mechanical energy into electrical energy and storing it during walking through clever mechanical design and energy conversion technology, which brings convenience to the user's daily life. The power-generating shoes have a wide range of application scenarios, especially suitable for military and rescue, outdoor sports and exploration fields, such as individual combat equipment, disaster relief, outdoor sports and exploration. The shoes can be military boots, the soles are filled with high-density flexible insoles, and the mechanical power generation unit 1 is arranged at the heel of the high-density flexible insoles.
