Description

Technical Field

[0002] In the field of energy conversion and utilization, internal combustion engine power generation devices are widely used in automobiles, ships, emergency power supplies, and other scenarios. Rotary internal combustion generators drive pistons in reciprocating linear motion by burning fuel. The pistons then drive a connecting mechanism, and the crankshaft and connecting rod mechanism converts this linear motion into rotational motion. Finally, the crankshaft drives the generator rotor to rotate, generating electricity. This type of internal combustion generator suffers from problems such as a long energy conversion chain and high mechanical losses, affecting power generation efficiency. Furthermore, the crankshaft-driven rotor rotation is non-uniform, leading to significant fluctuations in the generator's output power and impacting power quality.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0032] According to the first aspect of this application, please refer to Figure 1 A power generation device is provided, comprising a stator module 1, a mover module 2, a cylinder module 3, and a converter module 4.

[0033] Specifically, the moving module 2 is disposed within the stator module 1. The moving module 2 can be a permanent magnet structure. The stator module 1 includes a stator body 11 and a stator coil 12, with the stator coil 12 disposed on the stator body 11. In practical applications, the stator body 11 can be integrated into the housing of the power generation equipment. The stator module 1 has a hollow inner cavity, and the moving module 2 can be coaxially disposed within the hollow inner cavity of the stator module 1. The moving module 2 can perform horizontal reciprocating linear motion along the axial direction of the stator module 1.

[0034] The cylinder module 3 includes a first cylinder unit 31, a second cylinder unit 32, and a connecting rod unit 33. The first cylinder unit 31 and the second cylinder unit 32 are located at opposite ends of the stator module 1. The mover module 2 is connected to the connecting rod unit 33, and the connecting rod unit 33 is also connected to the first cylinder unit 31 and the second cylinder unit 32. The first cylinder unit 31 and the second cylinder unit 32 are symmetrically fixed at both ends of the stator module 1 along the axial direction. The connecting rod unit 33 passes through the inner cavity of the stator module 1 along the axial direction. Both ends of the connecting rod unit 33 are drively connected to the first cylinder unit 31 and the second cylinder unit 32, and the middle part of the connecting rod unit 33 can be fixedly connected to the mover module 2, thereby realizing the linkage between the mover module 2 and the cylinder module 3.

[0035] The adapter module 4 includes a crank unit 41 and a slider unit 42, which are rotatably connected. The crank unit 41 and the slider unit 42 can be connected via a revolute joint.

[0036] The connecting rod unit 33 has a slide rail 33a, and a slider unit 42 is movably disposed in the slide rail 33a. The crank unit 41 is configured to drive the first cylinder unit 31 and the second cylinder unit 32 to cooperate and drive the mover module 2 to move, so that the mover module 2 and the stator module 1 cooperate to generate electrical energy. The slide rail 33a is located in the middle of the connecting rod unit 33. The slide rail 33a can extend radially along the hollow inner cavity of the stator module 1. The slider unit 42 can be disposed in the slide rail 33a in a manner including but not limited to sliding fit, so that the slider unit 42 can perform reciprocating linear motion along the slide rail 33a.

[0037] Thus, when the power generation device starts, the crank unit 41 can be driven by an external drive mechanism to rotate, causing the slider unit 42 to reciprocate linearly along the radial direction of the stator module 1 within the slide rail 33a. This, in turn, drives the connecting rod unit 33 to reciprocate linearly along the axial direction of the stator module 1, thereby driving the first cylinder unit 31 and the second cylinder unit 32 to cooperate in completing the four-stroke coordination of intake, compression, power, and exhaust. Subsequently, after the first cylinder unit 31 and the second cylinder unit 32 have stabilized, the drive mechanism stops working. Under the inertia of the crank unit 41, the first cylinder unit 31 and the second cylinder unit 32 can cooperate with each other to continue driving the mover module 2 to perform synchronous horizontal reciprocating linear motion relative to the stator module 1. This causes the mover module 2 to cut the magnetic field lines generated by the stator module 1 to generate electricity, realizing the conversion of mechanical energy into electrical energy. By cooperating with the slider unit 42 and the slide rail 33a, the adapter module 4 and the connecting rod unit 33 form a Scottish yoke mechanism. This not only enables the connecting rod unit 33 to reciprocate linearly between the first cylinder unit 31 and the second cylinder unit 32, but also constrains the limit position of the connecting rod unit 33 during the reciprocating linear motion. This helps to improve the accuracy of the top dead center and bottom dead center positions of the first piston 312 and the second piston 322 connected at both ends of the connecting rod unit 33 within the corresponding cylinder liners, making the cooperation process of the first cylinder unit 31 and the second cylinder unit 32 more stable and improving the stability of the power generation process of the power generation equipment.

[0038] It should be noted that when the power generation equipment is started, the crank unit 41 can rotate clockwise or counterclockwise under the action of an external drive mechanism. In this application, the clockwise movement of the crank unit 41 is used as an example for illustration.

[0039] Through the above technical solution, a slide rail 33a is provided on the connecting rod unit 33. By rotating the slider unit 42 and the crank unit 41, the slider unit 42 cooperates with the slide rail 33a to realize the transmission connection between the connecting rod unit 33 and the crank unit 41. During the process of the first cylinder unit 31 and the second cylinder unit 32 driving the actuator module 2 to move within the stator module 1 to cut the magnetic field lines and generate electricity through the connecting rod unit 33, the crank unit 41 can not only control the piston start at both ends of the connecting rod unit 33, but also, with the cooperation of the slider unit 42 and the slide rail 33a, control the piston at the upper and lower stop points of the corresponding cylinder unit and the reversing process in the reciprocating motion. This enables the internal components of the power generation system to coordinate and cooperate, improving the operational stability and reliability of the power generation system.

[0040] In some embodiments, please refer to Figure 1 and Figure 2The connecting rod unit 33 includes a first connecting rod 331 and a second connecting rod 332. The first connecting rod 331 is connected to the first cylinder unit 31, and the second connecting rod 332 is connected to the second cylinder unit 32. The first connecting rod 331 has a first connecting part 3311, and the second connecting rod 332 has a second connecting part 3321. The first connecting part 3311 and the second connecting part 3321 are connected to each other to form a slide 33a.

[0041] Specifically, the first connecting rod 331 and the second connecting rod 332 have the same structure. The end of the first connecting rod 331 away from the stator module 1 is connected to the first cylinder unit 31, and the end of the second connecting rod 332 away from the stator module 1 is connected to the second cylinder unit 32. The end of the first connecting rod 331 near the stator module 1 may have a first connecting portion 3311 formed by means including but not limited to integral molding. The end of the second connecting rod 332 near the stator module 1 may also have a second connecting portion 3321 formed by means including but not limited to integral molding. Both the first connecting portion 3311 and the second connecting portion 3321 may have a U-shaped frame structure. The first connecting portion 3311 and the second connecting portion 3321 may be fixedly connected by means including but not limited to bolts, thereby forming a square frame structure extending radially along the hollow inner cavity of the stator module 1 between the first connecting rod 331 and the second connecting rod 332. Subsequently, a guide groove, i.e., a slide rail 33a, can be formed within the square frame structure formed by the first connecting part 3311 and the second connecting part 3321, arranged radially along the hollow inner cavity of the stator module 1. The inner wall of the slide rail 33a can be polished for wear resistance to extend its service life. In this way, the first connecting part 3311 and the second connecting part 3321 can form a slide rail 33a to guide the slider unit 42, realizing the conversion and coordination between the crank unit 41 and the connecting rod unit 33 in rotational and linear motion.

[0042] In some embodiments, please refer to Figure 1 The first connecting part 3311 and the second connecting part 3321 are located inside the stator module 1, and the moving part module 2 is disposed in at least one of the first connecting part 3311 and the second connecting part 3321.

[0043] Specifically, the moving module 2 can be a ring-shaped permanent magnet structure. The square frame structure jointly formed by the first connecting part 3311 and the second connecting part 3321 is arranged coaxially with the stator module 1. The moving module 2 can be fixed to the outer wall of one or both of the first connecting part 3311 and the second connecting part 3321 by means including but not limited to clamps or screws. In this way, by placing the entire square frame structure jointly formed by the first connecting part 3311 and the second connecting part 3321 in the hollow cavity of the stator module 1, the moving module 2 can always perform reciprocating linear motion within the hollow cavity of the stator module 1. This allows the moving module 2 to cut the magnetic field lines of the stator module 1 during the entire reciprocating linear motion, making full use of the movement of the moving module 2 and ensuring the power conversion efficiency of the generating device.

[0044] It should be noted that an air gap is reserved between the outer circumferential surface of the moving module 2 and the inner circumferential surface of the stator module 1, which can prevent the moving module 2 from rubbing against the stator module 1 when it moves, thus ensuring the magnetic energy conversion efficiency between the moving module 2 and the stator module 1.

[0045] In some embodiments, please Figure 1 Further reference Figure 2 The crank unit 41 includes a crank body 411 and a crank shaft 412. The crank body 411 is disposed at the end of the crank shaft 412, and the crank shaft 412 is rotatably connected to the slider unit 42.

[0046] Specifically, two crank bodies 411 can be provided, and the two crank bodies 411 can be symmetrically arranged at both ends of the crankshaft 412. At least one of the crank bodies 411 is connected to the output end of an external drive mechanism for starting, thereby driving the crank body 411 to rotate. The middle part of the crankshaft 412 can be rotatably connected to the slider unit 42, thereby realizing the rotational arrangement of the crank unit 41 and the slider unit 42.

[0047] Furthermore, in this embodiment, a counterweight 4111 may also be provided on the crank body 411. The counterweight 4111 can be fixed to the crank body 411 by a third fixing member 4112. The third fixing member 4112 may be in the form of, but is not limited to, bolts. During the process of the crank unit 41 driving the connecting rod unit 33 to reciprocate linearly between the first cylinder unit 31 and the second cylinder unit 32 through the slider unit 42, by providing the counterweight 4111 on the crank body 411, the crank body 411 can continue to rotate under the inertia of the counterweight 4111. Thus, even after the subsequent drive mechanism is closed, the first cylinder unit 31 and the second cylinder unit 32 can continue to reciprocate in the four-stroke cycle of intake, compression, power, and exhaust, thereby realizing the continuous power generation of the power generation device.

[0048] In some embodiments, please Figure 1 and Figure 2 Further reference Figure 3 The slider unit 42 includes a base 421, a contact 422, and a connecting rod bearing 423. The base 421 is located inside the slide rail 33a. The contact 422 is disposed on the base 421. The base 421 is movably connected to the slide rail 33a through the contact 422. The connecting rod bearing 423 is disposed on the base 421. The base 421 is rotatably connected to the crank unit 41 through the connecting rod bearing 423.

[0049] Specifically, the base 421 can be, but is not limited to, a square block structure. The structure of the base 421 can be adapted to the structure of the slide rail 33a, allowing the base 421 to reciprocate linearly along the slide rail 33a. Meanwhile, the contact element 422 can be, but is not limited to, a linear sliding bearing. The contact element 422 can be fixedly mounted on the two side walls of the base 421 by the second fixing member 425, allowing the outer side of the contact element 422 to contact the inner wall of the slide rail 33a. Lubricating oil can be supplied between the outer side of the contact element 422 and the inner wall of the slide rail 33a to reduce mechanical wear between the contact element 422 and the slide rail 33a. Furthermore, the connecting rod bearing 423 can be, but is not limited to, a wear-resistant alloy bearing. A through hole can be provided in the center of the base 421. The connecting rod bearing 423 can be disposed within the through hole in the center of the base 421. The middle part of the crankshaft 412 can be inserted into the connecting rod bearing 423, so that the base 421 can form a rotating pair with the crankshaft 412 through the connecting rod bearing 423. The inner circle surface of the connecting rod bearing 423 and the surface of the crankshaft 412 can be lubricated by supplying lubricating oil to reduce the mechanical wear between the connecting rod bearing 423 and the crankshaft 412.

[0050] It should be noted that in this embodiment, the slider unit 42 includes at least two bases 421. This application uses the form of the slider unit 42 including two bases 421 as an example for illustration. The two bases 421 can be fixedly connected by a first fastener 424. The first fastener 424 can be in the form of, but is not limited to, bolts. The sidewalls of the two bases 421 that are in contact with each other are provided with semi-circular hole structures. Thus, when the two bases 421 are connected, a through-hole structure for fixing the connecting rod bearing 423 can be formed. By designing the bases 421 in a modular assembly form, the disassembly and maintenance of the internal connecting rod bearing 423 is facilitated, reducing the later maintenance cost of the slider unit 42.

[0051] In some embodiments, please refer to Figure 1The first cylinder block unit 31 includes a first cylinder liner 311 and a first piston 312. The first piston 312 is movably disposed within the first cylinder liner 311. The first cylinder liner 311 has a first combustion chamber 311a and a first buffer chamber 311b located on both sides of the first piston 312. The first buffer chamber 311b is adjacent to the stator module 1 relative to the first combustion chamber 311a. The first buffer chamber 311b is configured to buffer and protect the first piston 312 when the first cylinder block unit 31 performs a power stroke. The second cylinder block unit 32 includes a second cylinder liner 321 and a second piston 322. The second piston 322 is movably disposed within the second cylinder liner 321. The second cylinder liner 321 has a second combustion chamber 321a and a second buffer chamber 321b located on both sides of the second piston 322. The second buffer chamber 321b is adjacent to the stator module 1 relative to the second combustion chamber 321a. The second buffer chamber 321b is configured to buffer and protect the second piston 322 when the second cylinder block unit 32 performs a power stroke.

[0052] Specifically, the first cylinder block unit 31 and the second cylinder block unit 32 can be internal combustion cylinder block structures with identical structures. The first piston 312 is disposed in the inner cavity of the first cylinder liner 311 and can reciprocate linearly along the axis of the first cylinder liner 311. The first piston 312 divides the inner cavity of the first cylinder liner 311 into two independent chambers, namely the first combustion chamber 311a and the first buffer chamber 311b. The first buffer chamber 311b is disposed relative to the first combustion chamber 311a and closer to the stator module 1. The second piston 322 divides the inner cavity of the second cylinder liner 321 into two independent chambers, the second combustion chamber 321a and the second buffer chamber 321b. The second buffer chamber 321b is disposed relative to the second combustion chamber 321a and closer to the stator module 1. Both the first buffer chamber 311b and the second buffer chamber 321b are pneumatic buffer structures.

[0053] Please refer to the above as well. Figure 4 In this embodiment, when the crankshaft of crank unit 41 (i.e., crank body 411 in this application) rotates clockwise between 0° and 180°, the second cylinder block unit 32 is in the compression stroke; when the crankshaft of crank unit 41 rotates clockwise between 180° and 360°, the second cylinder block unit 32 is in the power stroke; when the crankshaft of crank unit 41 rotates clockwise between 360° and 540°, the second cylinder block unit 32 is in the exhaust stroke; and when the crankshaft of crank unit 41 rotates clockwise between 540° and 720°, the second cylinder block unit 32 is in the intake stroke. Figure 4 As shown, when the second cylinder block unit 32 is in the initial stage of the power stroke, the combustible compressed gas in the second combustion chamber 321a expands and does work, and the linear sliding bearing used to connect the slider unit 42 and the connecting rod unit 33 reaches its peak force (i.e., Figure 4During the selected phase (within the Chinese frame), the structure of contact components such as linear sliding bearings is easily damaged.

[0054] To address the aforementioned issues, during the power stroke of the first cylinder unit 31 and the second cylinder unit 32, the compressed gas in the corresponding buffer chamber can act as an air spring, applying a reverse force to the first piston 312 or the second piston 322. This can counteract the instantaneous load on the piston caused by the explosive pressure of the gas generated by fuel combustion, thereby reducing the contact pressure of the sliding bearing friction pair in the transfer module 4, reducing abnormal wear of the internal structure of the transfer module 4, and also providing buffer protection for the first piston 312 and the second piston 322.

[0055] In some embodiments, please refer to Figure 1 and Figure 2 The first connecting rod 331 also includes a first main body 3312, one end of which is connected to the first connecting part 3311, and the other end of which extends into the first cylinder liner 311 and is connected to the first piston 312. The second connecting rod 332 also includes a second main body 3322, one end of which is connected to the second connecting part 3321, and the other end of which extends into the second cylinder liner 321 and is connected to the second piston 322.

[0056] Specifically, both the first main body portion 3312 and the second main body portion 3322 are slender rod-shaped structures. One end of the first main body portion 3312 can be integrally formed or welded to the first connecting portion 3311, while the other end can pass through the end through-hole of the first cylinder liner 311 and extend into the inner cavity of the first cylinder liner 311. The end of the first main body portion 3312 located inside the first cylinder liner 311 is hinged to the first piston 312, realizing the transmission connection between the first connecting rod 331 and the first piston 312, thereby enabling the first connecting rod 331 to drive the first piston 312 to move within the first cylinder liner 311.

[0057] Furthermore, one end of the second main body 3322 can be integrally formed or welded to the second connecting part 3321, while the other end can extend into the inner cavity of the second cylinder liner 321 through the end through hole. The end of the second main body 3322 located inside the second cylinder liner 321 is hinged to the second piston 322, realizing the transmission connection between the second connecting rod 332 and the second piston 322, thereby enabling the second connecting rod 332 to drive the second piston 322 to move within the second cylinder liner 321.

[0058] It should be noted that both the first main body portion 3312 and the second main body portion 3322 have pin holes at one end located within the corresponding cylinder liner, and both the first piston 312 and the second piston 322 also have pin holes. This allows the pin holes of the first main body portion 3312 and the first piston 312 to be aligned, and a hinged connection between the first main body portion 3312 and the first piston 312 can be achieved through the engagement between the piston pin and the pin hole. Similarly, it is easy to understand that the pin holes of the second main body portion 3322 and the second piston 322 can be aligned, and a hinged connection between the second main body portion 3322 and the second piston 322 can also be achieved through the engagement between the piston pin and the pin hole.

[0059] In some embodiments, please refer to Figure 1 and Figure 2 The first cylinder liner 311 is provided with a first intake component 3111 and a first exhaust component 3112, both of which are configured to communicate with the first buffer chamber 311b. The second cylinder liner 321 is provided with a second intake component 3211 and a second exhaust component 3212, both of which are configured to communicate with the second buffer chamber 321b.

[0060] Specifically, both the first intake component 3111 and the first exhaust component 3112 are mounted on the cylinder wall of the first cylinder liner 311. Both the first intake component 3111 and the first exhaust component 3112 can be, but are not limited to, solenoid valves. One end of the first intake component 3111 is connected to an external compressed gas source, and the other end is connected to the first buffer chamber 311b. High-pressure compressed gas can be introduced into the first buffer chamber 311b through the first intake component 3111. One end of the first exhaust component 3112 is connected to the first buffer chamber 311b, and the other end is connected to the atmosphere. The first exhaust component 3112 can discharge the gas in the first buffer chamber 311b to the atmosphere to achieve pressure relief.

[0061] Furthermore, one end of the second air intake 3211 is connected to an external compressed gas source, and the other end of the second air intake 3211 is connected to the second buffer chamber 321b. High-pressure compressed gas can be introduced into the second buffer chamber 321b through the second air intake 3211. One end of the second exhaust 3212 is connected to the second buffer chamber 321b, and the other end of the second exhaust 3212 is connected to the atmosphere. The gas in the second buffer chamber 321b can be discharged to the atmosphere through the second exhaust 3212 to achieve pressure relief.

[0062] It should be noted that the first exhaust component 3112 and the second exhaust component 3212 can not only discharge the gas in the corresponding buffer chamber to the outside atmosphere to relieve pressure, but also open when the first cylinder unit 31 and the second cylinder unit 32 are in the exhaust stroke, according to the working state of the first cylinder unit 31 and the second cylinder unit 32, so that air in the atmosphere enters the corresponding buffer chamber, preventing negative pressure from being generated in the corresponding buffer chamber and hindering the movement of the internal piston.

[0063] In some embodiments, please refer to Figure 1 The power generation equipment also includes a control module 5, which is electrically connected to both the first air intake component 3111 and the first exhaust component 3112 to control at least one of them to open or close. The control module 5 is also electrically connected to both the second air intake component 3211 and the second exhaust component 3212 to control at least one of them to open or close.

[0064] Specifically, the control module 5 can be a programmable electronic control unit (ECU). The control module 5 can have a built-in microprocessor, memory, and drive circuitry. The control module 5 is electrically connected to both the first intake component 3111 and the first exhaust component 3112. The control module 5 can control the opening and closing of the first intake component 3111 and the first exhaust component 3112 by outputting high and low level electrical signals, thereby enabling functions such as inflation and depressurization control of the first buffer chamber 311b.

[0065] In addition, the signal output terminal of the control module 5 can also be electrically connected to the second air intake component 3211 and the second air exhaust component 3212. The control module 5 can also control the opening or closing of the second air intake component 3211 and the second air exhaust component 3212 respectively by outputting high and low level electrical signals, thereby realizing the functions of inflation and depressurization control of the second buffer chamber 321b.

[0066] In some embodiments, please refer to Figure 1 The first cylinder liner 311 is equipped with a first sensor 3113, which is located inside the first buffer chamber 311b. The first sensor 3113 is electrically connected to the control module 5 to detect the air pressure in the first buffer chamber 311b. The second cylinder liner 321 is equipped with a second sensor 3213, which is located inside the second buffer chamber 321b. The second sensor 3213 is electrically connected to the control module 5 to detect the air pressure in the second buffer chamber 321b.

[0067] Specifically, the first sensor 3113 is mounted on the cylinder wall of the first cylinder liner 311, and its detection end extends through the cylinder wall into the first buffer chamber 311b, allowing direct contact between the detection end and the gas inside the first buffer chamber 311b, thus enabling real-time detection of the gas pressure within the first buffer chamber 311b. The signal output terminal of the first sensor 3113 is electrically connected to the signal input terminal of the control module 5, enabling the conversion of the collected analog gas pressure signal into a digital signal for transmission to the control module 5.

[0068] Furthermore, the second sensor 3213 is mounted on the cylinder wall of the second cylinder liner 321, and its detection end extends through the cylinder wall into the second buffer chamber 321b, allowing direct contact between the detection end of the second sensor 3213 and the gas inside the second buffer chamber 321b, thus enabling real-time detection of the gas pressure inside the second buffer chamber 321b. The signal output terminal of the second sensor 3213 is electrically connected to the signal input terminal of the control module 5, enabling the conversion of the collected analog gas pressure signal into a digital signal before transmission to the control module 5.

[0069] In some embodiments, please refer to Figure 1 The power generation equipment also includes a third sensor 6, which is disposed in at least one of the first connecting part 3311 and the second connecting part 3321. The third sensor 6 is electrically connected to the control module 5 to detect the position of the first piston 312 in the first cylinder liner 311 and / or the position of the second piston 322 in the second cylinder liner 321.

[0070] Specifically, the third sensor 6 can be a laser displacement sensor. The third sensor 6 can be disposed on the outer wall of one or both of the first connecting portion 3311 and the second connecting portion 3321. The detection end of the third sensor 6 is positioned facing the end of the first cylinder liner 311 or the second cylinder liner 321, and the signal output end of the third sensor 6 is electrically connected to the signal input end of the control module 5. Through the third sensor 6, the relative distance between the first connecting portion 3311 or the second connecting portion 3321 of the connecting rod unit 33 and the end of the first cylinder liner 311 or the second cylinder liner 321 can be detected in real time. Furthermore, by combining this with the preset position conversion relationship within the control module 5, the real-time position of the first piston 312 within the first cylinder liner 311 and the real-time position of the second piston 322 within the second cylinder liner 321 can be indirectly obtained. Thus, by setting the first sensor 3113, the stroke distance of the first piston 312 and the second piston 322 from the corresponding top dead center and bottom dead center can be indirectly known, so as to control the opening and closing of the first intake component 3111, the first exhaust component 3112, the second intake component 3211 and the second exhaust component 3212.

[0071] According to the second aspect of this application, please refer to Figure 5 This application also provides a power generation system, including the power generation equipment, power conversion module 7 and energy storage module 8 in any of the above embodiments.

[0072] Specifically, the power conversion module 7 is electrically connected to the stator module 1 of the power generation equipment. The power conversion module 7 can be, but is not limited to, devices such as power converters. The signal input terminal of the power conversion module 7 is electrically connected to the coil 12 winding of the stator module 1 of the power generation equipment. The power conversion module 7 can receive the alternating induced current generated by the stator module 1, and can perform rectification, voltage regulation, filtering, and other processing on the alternating induced current to convert it into direct current that meets the energy storage requirements.

[0073] The energy storage module 8 is electrically connected to the power conversion module 7. The energy storage module 8 can be, but is not limited to, devices such as battery packs or energy storage capacitor banks. The input terminal of the energy storage module 8 is electrically connected to the signal output terminal of the power conversion module 7. The energy storage module 8 can store the DC power output from the power conversion module 7, realizing energy storage and subsequent power supply.

[0074] The power generation system has all the beneficial effects of the aforementioned power generation equipment, which will not be elaborated upon here.

[0075] According to the third aspect of this application, please refer to Figures 6 to 11 This application also provides a control method for a power generation device, the control method being based on the power generation device, and the control method includes: The crank unit 41 of the control transfer module 4 drives the connecting rod unit 33 to move, so that the connecting rod unit 33, through the cooperation of the first cylinder unit 31 and the second cylinder unit 32, drives the mover module 2 to move relative to the stator module 1, so that the mover module 2 and the stator module 1 cooperate to generate electrical energy.

[0076] Specifically, when the power generation system starts up, it can control the external drive mechanism to drive the crank unit 41 of the transfer module 4 to rotate clockwise or counterclockwise. In this application, the clockwise rotation of the crank unit 41 is used as an example. The clockwise rotation of the crank unit 41 can drive the slider unit 42 to reciprocate linearly within the slide rail 33a of the connecting rod unit 33. Under the reciprocating linear motion of the slider unit 42, the connecting rod unit 33 can be driven to reciprocate linearly along the axial direction of the stator module 1, so that the connecting rod unit 33 drives the first cylinder block unit 31 and the second cylinder block unit to cooperate with each other in the four-stroke processes of intake, compression, power, and exhaust. After either the first cylinder unit 31 or the second cylinder unit 32 of the power generation system completes one four-stroke cycle, the external drive mechanism is stopped. The first cylinder unit 31 and the second cylinder unit 32 cooperate to drive the connecting rod unit 33 to continuously perform reciprocating linear motion along the axial direction of the stator module 1. This drives the moving module 2, which is fixed on the connecting rod unit 33, to perform synchronous reciprocating linear motion relative to the stator module 1. This causes the moving module 2 to continuously cut the magnetic field lines of the stator module 1, generating an induced alternating current and thus generating electricity.

[0077] In some embodiments, please refer to Figure 8 and Figure 9 The control methods also include: The first cylinder block unit 31 includes a first cylinder liner 311 and a first piston 312. The first piston 312 is movably disposed within the first cylinder liner 311. The first cylinder liner 311 has a first combustion chamber 311a and a first buffer chamber 311b located on both sides of the first piston 312. The second cylinder block unit 32 includes a second cylinder liner 321 and a second piston 322. The second piston 322 is movably disposed within the second cylinder liner 321. The second cylinder liner 321 has a second combustion chamber 321a and a second buffer chamber 321b located on both sides of the second piston 322.

[0078] Specifically, as an example, such as Figure 8 As shown, the positions of the first piston 312 and the second piston 322 can be used as the initial positions of the power generation device. At this time, the first piston 312 is located at the top dead center of the first cylinder liner 311, and the first combustion chamber 311a discharges exhaust gas. The second piston 322 is located at the lower support point of the second cylinder liner 321, and the second combustion chamber 321a is filled with combustible gas mixture under normal pressure. The slider unit 42 is located at the leftmost end of the stator module 1 and in the middle of the slide rail 33a. The crank unit 41 rotates 180° clockwise, driving the slider unit 42 from... Figure 8 The position in the middle moves to Figure 9In the position of the slider unit 42, located at the rightmost end of the stator module 1, the slider unit 42 moves to the top of the slide rail 33a and then continues to the middle of the slide rail 33a. During the clockwise rotation of the crank unit 41 from 0° to 180°, the first piston 312 moves from the top dead center to the bottom dead center position within the first cylinder liner 311, and the second piston 322 moves from the bottom dead center to the top dead center position within the second cylinder liner 321. That is, this power generation device... Figure 8 Exercise to Figure 9 During the process, the first cylinder block unit 31 is in the intake stroke stage, and the second cylinder block unit 32 is in the compression stroke stage.

[0079] Furthermore, this control method also includes: The first cylinder unit 31 is controlled to perform the intake stroke, and the second cylinder unit 32 is controlled to perform the compression stroke, charging gas into the second buffer chamber 321b. The crank unit 41 of the power generator rotates clockwise, driving the connecting rod unit 33 to move towards the second cylinder unit 32. The control module 5 controls the first cylinder unit 31 to open the intake passage, allowing the combustible mixture to enter the first combustion chamber 311a, and the first cylinder unit 31 is in the intake stroke stage. At the same time, the connecting rod unit 33 can drive the second piston 322 of the second cylinder unit 32 to move towards the second combustion chamber 321a, compressing the combustible mixture in the second combustion chamber 321a, and the second cylinder unit 32 is in the compression stroke stage. During this process, the control module 5 controls the second intake component 3211 to open and the second exhaust component 3212 to close, allowing external compressed gas to continuously enter the second buffer chamber 321b through the second intake component 3211, thereby increasing the pressure of the second buffer chamber 321b.

[0080] When the second piston 322 reaches the first preset top dead center and the gas pressure value of the second buffer chamber 321b is within the first preset gas pressure value range, the gas filling into the second buffer chamber 321b is stopped; the fuel in the second combustion chamber 321a is controlled to burn, so that the second cylinder unit 32 performs the power stroke and the first cylinder unit 31 performs the compression stroke, thereby driving the drive module 2 to move relative to the stator module 1.

[0081] Specifically, the control module 5 of the power generation equipment can detect the position of the second piston 322 in real time through the third sensor 6. When the second piston 322 is detected to have reached the first preset top dead center, and the second sensor 3213 detects that the gas pressure value of the second buffer chamber 321b is within the first preset gas pressure range, the control module 5 immediately issues a command to close the second air intake 3211 and stop the gas from being supplied to the second buffer chamber 321b. In addition, when the second piston 322 reaches the first preset top dead center, the control module 5 controls the spark plug of the second combustion chamber 321a to ignite. The combustible mixture in the second combustion chamber 321a burns rapidly, expands, and does work, pushing the second piston 322 to move in the opposite direction, causing the second cylinder unit 32 to enter the power stroke. At the same time, it drives the connecting rod unit 33 to move towards the first cylinder unit 31, driving the first piston 312 to compress the combustible mixture in the first combustion chamber 311a, and the first cylinder unit 31 enters the compression stroke stage.

[0082] During the intake stroke of the first cylinder block unit 31 and the compression stroke of the second cylinder block unit 32, the connecting rod unit 33 drives the moving sub-module 2 to move from its leftmost end to its rightmost end along the axial direction of the stator module 1. The moving sub-module 2 cuts the magnetic field lines generated by the stator module 1 to generate an induced current, thereby generating electricity.

[0083] It should be noted that the first preset air pressure range can be 5 bar to 10 bar. In practical applications, the first preset air pressure range can be any value or any two ranges of 5 bar, 5.5 bar, 6 bar, 6.5 bar, 7 bar, 7.5 bar, 8 bar, 8.5 bar, 9 bar, 9.5 bar and 10 bar.

[0084] In some embodiments, please refer to Figures 7 to 9 During the process of filling the second buffer chamber 321b with gas, the position of the second piston 322 and the gas pressure value of the second buffer chamber 321b are detected in real time. Based on the first preset mapping relationship between the position of the second piston 322 and the gas pressure value of the second buffer chamber 321b, the gas pressure value of the second buffer chamber 321b is adjusted so that when the second piston 322 reaches the first preset top dead center, the gas pressure value of the second buffer chamber 321b is within the first preset gas pressure value range. During the compression stroke of the second cylinder unit 32, during the process of filling the second buffer chamber 321b with compressed gas, in order to ensure that the gas pressure of the second buffer chamber 321b is within the first preset gas pressure value range when the second piston 322 reaches the first preset top dead center, the gas pressure of the second buffer chamber 321b needs to be adaptively adjusted.

[0085] Specifically, the third sensor 6 can detect the real-time position of the second piston 322 and transmit it to the control module 5, and the second sensor 3213 can detect the real-time air pressure value of the second buffer chamber 321b and transmit it to the control module 5. The control module 5 synchronously collects and analyzes the above two signals.

[0086] The control module 5 can pre-store a first preset mapping relationship in its memory. This first preset mapping relationship can be a one-to-one correspondence curve between the position of the second piston 322 within the second cylinder liner 321 during the compression stroke of the second cylinder block unit 32 and a first preset air pressure range in the second buffer chamber 321b. Different positions of the second piston 322 during the compression stroke correspond to different preset air pressure ranges in the second buffer chamber 321b, achieving a gradient increase in air pressure. The control module 5 can compare the real-time collected positions of the second piston 322 and the air pressure value of the second buffer chamber 321b with the first preset mapping relationship, and adjust the air pressure value of the second buffer chamber 321b in real time based on the comparison result, ensuring that the air pressure value of the second buffer chamber 321b is within the range of 5 bar to 10 bar when the second piston 322 reaches the first preset top dead center. The specific method for adjusting the air pressure of the second buffer chamber 321b can be as follows: If the position of the second piston 322 is close to the first preset top dead center and the air pressure value of the second buffer chamber 321b is greater than the corresponding first preset air pressure value range, the air pressure difference to be corrected is calculated according to the first preset mapping relationship, the air pressure correction coefficient of the second buffer chamber 321b is set, the second air intake component 3211 is closed, and the second exhaust component 3212 is opened briefly to exhaust and depressurize the second buffer chamber 321b, so that when the second piston 322 reaches the first preset top dead center, the air pressure in the second buffer chamber 321b is within the first preset air pressure value range.

[0087] If the position of the second piston 322 is close to the first preset top dead center and the air pressure value of the second buffer chamber 321b is less than the corresponding first preset air pressure value range, the air pressure difference to be corrected is calculated according to the first preset mapping relationship, the air pressure correction coefficient of the second buffer chamber 321b is set, and the charging pressure of the second air inlet 3211 is increased for a short time to rapidly pressurize the second buffer chamber 321b so that when the second piston 322 reaches the first preset top dead center, the air pressure in the second buffer chamber 321b is within the first preset air pressure value range.

[0088] If the second piston 322 is close to the first preset top dead center and the air pressure in the second buffer chamber 321b is within the corresponding first preset air pressure range, the second air inlet 3211 is closed, and gas is stopped being supplied to the second buffer chamber 321b. In this scenario, if the second piston 322 further approaches the first preset top dead center, the space in the second buffer chamber 321b increases, and the air pressure in the second buffer chamber decreases. If the air pressure in the second buffer chamber 321b is less than the corresponding first preset air pressure range, the pressure difference to be corrected can be calculated according to the first preset mapping relationship, the air pressure correction coefficient of the second buffer chamber 321b can be set, and the second air inlet 3211 can be opened briefly to supply gas to the second buffer chamber 321b, so that when the second piston 322 finally reaches the first preset top dead center, the air pressure in the second buffer chamber 321b is within the first preset air pressure range.

[0089] It should be noted that when the second piston 322 is one-third or one-quarter of the stroke distance from the first preset top dead center, the second piston 322 is in a state close to the first preset top dead center.

[0090] In some embodiments, please refer to Figures 7 to 9 The control methods also include: During the intake stroke of the first cylinder block unit 31 and the compression stroke of the second cylinder block unit 32, gas is introduced into the first combustion chamber 311a and gas is discharged from the first buffer chamber 311b.

[0091] Specifically, during the intake stroke of the first cylinder block unit 31 and the compression stroke of the second cylinder block unit 32, the control module 5 can also control the intake valve (not shown in the figure) of the first combustion chamber 311a of the first cylinder block unit 31 to open, continuously charging the first combustion chamber 311a with combustible gas mixture. At the same time, the control module 5 also controls the first exhaust component 3112 to remain open, so as to discharge the atmospheric pressure gas in the first buffer chamber 311b to the atmosphere, keeping the first buffer chamber 311b at atmospheric pressure, avoiding the resistance of the gas in the first buffer chamber 311b when the first piston 312 moves in the first cylinder liner 311, and ensuring the smoothness of the intake stroke of the first cylinder block unit 31.

[0092] In some embodiments, please refer to Figure 6 , Figure 9 and Figure 10 The control methods also include: The first cylinder unit 31 performs the compression stroke, and the second cylinder unit 32 performs the power stroke, filling the first buffer chamber 311b with gas. The crank unit 41 rotates 360° clockwise, driving the slider unit 42 from... Figure 9 The position in the middle moves to Figure 10In the position of the slider unit 42, located at the leftmost end of the stator module 1, the slider unit 42 moves to the bottom of the slide rail 33a and then continues to the middle of the slide rail 33a. During the clockwise rotation of the crank unit 41 from 180° to 360°, the first piston 312 moves from the bottom dead center to the top dead center position within the first cylinder liner 311, and the second piston 322 moves from the top dead center position to the lower pivot position within the second cylinder liner 321. That is, this power generation device... Figure 9 Exercise to Figure 10 During the process, the first cylinder block unit 31 is in the compression stroke stage, and the second cylinder block unit 32 is in the power stroke stage.

[0093] When the first piston 312 reaches the second preset top dead center and the gas pressure value of the first buffer chamber 311b is within the second preset gas pressure value range, the gas filling into the first buffer chamber 311b is stopped; the fuel in the first combustion chamber 311a is controlled to burn, so that the first cylinder unit 31 performs the power stroke and the second cylinder unit 32 performs the exhaust stroke, thereby driving the drive module 2 to move relative to the stator module 1.

[0094] Specifically, the combustion in the second combustion chamber 321a drives the second piston 322 to move in the opposite direction, which in turn drives the first piston 312 towards the first combustion chamber 311a via the connecting rod unit 33, compressing the combustible mixture within the first combustion chamber 311a. The first cylinder block unit 31 is in the compression stroke phase. Simultaneously, the second piston 322 continues to move in the opposite direction within the second cylinder liner 321 until the power stroke phase of the second cylinder block unit 32 is completed. During this process, the control module 5 controls the opening of the first intake component 3111 and the closing of the first exhaust component 3112, allowing external compressed gas to continuously fill the first buffer chamber 311b through the first intake component 3111, thus pressurizing the first buffer chamber 311b.

[0095] In this embodiment, the control module 5 of the power generation equipment can detect the position of the first piston 312 in real time through the third sensor 6. When the first piston 312 is detected to have reached the second preset top dead center, and the first sensor 3113 detects that the gas pressure value of the first buffer chamber 311b is within the second preset gas pressure range, the control module 5 immediately issues a command to close the first air intake component 3111 and stop charging gas into the first buffer chamber 311b. In addition, when the first piston 312 reaches the second preset top dead center, the control module 5 controls the spark plug of the first combustion chamber 311a to ignite, and the combustible mixture in the first combustion chamber 311a burns rapidly, expands and does work, pushing the first piston 312 to move in the opposite direction, so that the first cylinder unit 31 enters the power stroke, and at the same time drives the connecting rod unit 33 to move towards the second cylinder unit 32, driving the second piston 322 to discharge the exhaust gas in the second combustion chamber 321a, and the second cylinder unit 32 enters the exhaust stroke stage.

[0096] During the compression stroke of the first cylinder unit 31 and the power stroke of the second cylinder unit 32, the connecting rod unit 33 drives the moving sub-module 2 to move from its rightmost end to its leftmost end along the axial direction of the stator module 1. The moving sub-module 2 cuts the magnetic field lines generated by the stator module 1 to generate an induced current, thereby generating electricity.

[0097] It should be noted that the second preset air pressure range can be 5 bar to 10 bar. In practical applications, the second preset air pressure range can be any value or any two ranges of 5 bar, 5.5 bar, 6 bar, 6.5 bar, 7 bar, 7.5 bar, 8 bar, 8.5 bar, 9 bar, 9.5 bar and 10 bar.

[0098] In some embodiments, please refer to Figure 6 , Figure 9 and Figure 10 During the process of filling the first buffer chamber 311b with gas, the position of the first piston 312 and the gas pressure value of the first buffer chamber 311b are detected in real time. Based on a second preset mapping relationship between the position of the first piston 312 and the gas pressure value of the first buffer chamber 311b, the gas pressure value of the first buffer chamber 311b is adjusted so that when the first piston 312 reaches the second preset top dead center, the gas pressure value of the first buffer chamber 311b is within the second preset gas pressure value range. During the compression stroke phase of the first cylinder unit 31, during the process of filling the first buffer chamber 311b with compressed gas, in order to ensure that the gas pressure of the first buffer chamber 311b is within the second preset gas pressure value range when the first piston 312 reaches the first preset top dead center, the gas pressure of the first buffer chamber 311b needs to be adaptively adjusted.

[0099] Specifically, the third sensor 6 can detect the real-time position of the first piston 312 and transmit it to the control module 5, and the first sensor 3113 can detect the real-time air pressure value of the first buffer chamber 311b and transmit it to the control module 5. The control module 5 synchronously collects and analyzes the above two signals.

[0100] The control module 5 can pre-store a second preset mapping relationship in its memory. This second preset mapping relationship can be a one-to-one correspondence curve between the position of the first piston 312 within the first cylinder liner 311 during the compression stroke of the first cylinder block unit 31 and a second preset air pressure range in the first buffer chamber 311b. Different positions of the first piston 312 during the compression stroke correspond to different preset air pressure ranges in the first buffer chamber 311b, achieving a gradient increase in air pressure. The control module 5 can compare the real-time collected positions of the first piston 312 and the air pressure value of the first buffer chamber 311b with the second preset mapping relationship, and adjust the air pressure value of the first buffer chamber 311b in real time based on the comparison result, ensuring that the air pressure value of the first buffer chamber 311b is within the range of 5 bar to 10 bar when the first piston 312 reaches the second preset top dead center. The specific method for adjusting the air pressure of the first buffer chamber 311b can be as follows: If the position of the first piston 312 is close to the second preset top dead center and the air pressure value of the first buffer chamber 311b is greater than the corresponding second preset air pressure value range, the air pressure difference to be corrected is calculated according to the second preset mapping relationship, the air pressure correction coefficient of the first buffer chamber 311b is set, the first air intake component 3111 is closed, and the first exhaust component 3112 is opened for a short time to exhaust and depressurize the first buffer chamber 311b, so that when the first piston 312 reaches the second preset top dead center, the air pressure in the first buffer chamber 311b is within the second preset air pressure value range.

[0101] If the position of the first piston 312 is close to the second preset top dead center and the air pressure value of the first buffer chamber 311b is less than the corresponding second preset air pressure value range, the air pressure difference to be corrected is calculated according to the second preset mapping relationship, the air pressure correction coefficient of the first buffer chamber 311b is set, and the charging pressure of the first air inlet 3111 is increased for a short time to rapidly pressurize the first buffer chamber 311b so that when the first piston 312 reaches the second preset top dead center, the air pressure in the first buffer chamber 311b is within the second preset air pressure value range.

[0102] If the first piston 312 is close to the second preset top dead center and the air pressure in the first buffer chamber 311b is within the corresponding second preset air pressure range, the first air inlet 3111 is closed, and gas is stopped being supplied to the first buffer chamber 311b. In this scenario, if the first piston 312 further approaches the second preset top dead center, the space in the first buffer chamber 311b increases, and the air pressure in the first buffer chamber 311b decreases. If the air pressure in the first buffer chamber 311b is less than the corresponding second preset air pressure range, the pressure difference to be corrected can be calculated according to the second preset mapping relationship, the air pressure correction coefficient of the first buffer chamber 311b can be set, and the first air inlet 3111 can be opened briefly to supply gas to the first buffer chamber 311b, so that when the first piston 312 finally reaches the first preset top dead center, the air pressure in the first buffer chamber 311b is within the second preset air pressure range.

[0103] It should be noted that when the first piston 312 is one-third or one-quarter of the stroke distance from the second preset top dead center, the first piston 312 is in a state close to the second preset top dead center.

[0104] In some embodiments, please refer to Figure 7 , Figure 9 and Figure 10 The control methods also include: During the compression stroke of the first cylinder unit 31 and the power stroke of the second cylinder unit 32, the gas in the second buffer chamber 321b is discharged.

[0105] Specifically, during the compression stroke of the first cylinder unit 31 and the power stroke of the second cylinder unit 32, the control module 5 can also control the second exhaust component 3212 to open, venting the compressed gas in the second buffer chamber 321b to the atmosphere. This reduces the resistance of the second piston 322 to the gas in the second buffer chamber 321b when it travels within the second cylinder liner 321, preventing the effective thrust generated by the second cylinder unit 32 during its power stroke from being completely offset by the compressed gas in the second buffer chamber 321b. This ensures that the second cylinder unit 32 can transmit power to the first cylinder unit 31 through the connecting rod unit 33, enabling the first cylinder unit 31 to successfully complete its compression stroke.

[0106] It should be noted that, as Figure 4 As shown, the second cylinder block unit 32 causes the linear sliding bearing to reach its peak force (i.e., ...) during the initial stage of the power stroke. Figure 4 During the selected phase (as shown in the Chinese box), the linear sliding bearing and other contact components are prone to damage. To address this issue, during the initial power stroke of the second cylinder block unit 32, after the spark plug in the second combustion chamber 321a ignites, the second exhaust pipe 3212 needs to be briefly closed, keeping the second buffer chamber 321b in a temporarily sealed state. This allows the compressed gas in the second buffer chamber 321b to act as an air spring during the instantaneous combustion of the combustible mixture in the second combustion chamber 321a, providing sufficient reverse buffering for the second piston 322. This counteracts the instantaneous load on the piston caused by the explosive pressure of the combustion gases, thereby reducing the contact pressure of the sliding bearing friction pair in the transfer module 4, reducing abnormal wear on the internal structure of the transfer module 4, and simultaneously providing buffer protection for the second piston 322. Subsequently, the control module 5 controls the second exhaust pipe 3212 to open, venting the compressed gas in the second buffer chamber 321b to the atmosphere, preventing it from affecting the movement of the second piston 322 within the second cylinder liner 321.

[0107] In some embodiments, please refer to Figure 10 The control methods also include: The first cylinder block unit 31 is controlled to perform the power stroke, and the second cylinder block unit 32 performs the exhaust stroke, discharging the gas in the first buffer chamber 311b and the second combustion chamber 321a, and filling the second buffer chamber 321b with gas.

[0108] Specifically, as the crank unit 41 continues to rotate clockwise, during the rotation of the crank unit 41 from 360° to 540° clockwise, the first piston 312 moves from the top dead center (TDC) position within the first cylinder liner 311 to the bottom dead center (BDC) position, and the second piston 322 moves from the BDC position within the second cylinder liner 321 to the TDC position. That is, the first cylinder unit 31 of the power generator is in the power stroke phase, and the second cylinder unit 32 is in the exhaust stroke phase.

[0109] In this embodiment, during the power stroke of the first cylinder unit 31 and the exhaust stroke of the second cylinder unit 32, the control module 5 can also control the opening of the first exhaust component 3112 to discharge the compressed gas in the first buffer chamber 311b to the atmosphere. This reduces the resistance of the first piston 312 to the gas in the first buffer chamber 311b when it travels within the first cylinder liner 311, preventing the effective thrust generated by the first cylinder unit 31 during its power stroke from being completely offset by the compressed gas in the first buffer chamber 311b. This ensures that the first cylinder unit 31 can transmit power to the second cylinder unit 32 through the connecting rod unit 33, allowing the second cylinder unit 32 to successfully complete its exhaust stroke. Simultaneously, during the exhaust stroke of the second cylinder unit 32, the control module 5 controls the opening of the second exhaust component 3212 to allow external air to enter the second buffer chamber 321b, preventing negative pressure in the second buffer chamber 321b from affecting the second piston 322's discharge of exhaust gas from the second combustion chamber 321a.

[0110] It should be noted that since the structures of the first cylinder block unit 31 and the second cylinder block unit 32 are completely identical, their working states at the beginning of the power stroke are the same, such as... Figure 4 As shown, the first cylinder block unit 31 also causes the linear sliding bearing to reach its peak force during the initial stage of the power stroke (i.e., Figure 4The phases highlighted in the Chinese box can easily damage the contact components such as linear sliding bearings. To address this issue, during the initial power stroke of the first cylinder block unit 31, after the spark plug in the first combustion chamber 311a ignites, the first exhaust pipe 3112 needs to be briefly closed, keeping the first buffer chamber 311b in a temporarily sealed state. This allows the compressed gas in the first buffer chamber 311b to act as an air spring during the instantaneous combustion of the combustible mixture in the first combustion chamber 311a, providing sufficient reverse buffering for the first piston 312. This counteracts the instantaneous load on the piston caused by the explosive pressure of the combustion gases, thereby reducing the contact pressure of the sliding bearing friction pair in the transfer module 4, reducing abnormal wear on the internal structure of the transfer module 4, and simultaneously providing buffer protection for the first piston 312. Subsequently, the control module 5 controls the first exhaust pipe 3112 to open, venting the compressed gas in the first buffer chamber 311b to the atmosphere, preventing it from affecting the movement of the first piston 312 within the first cylinder liner 311.

[0111] During the power stroke of the first cylinder block unit 31 and the exhaust stroke of the second cylinder block unit 32, the connecting rod unit 33 drives the moving module 2 to move from its leftmost end to its rightmost end along the axial direction of the stator module 1. The moving module 2 cuts the magnetic field lines generated by the stator module 1 to generate an induced current, thereby generating electricity.

[0112] In some embodiments, please refer to Figure 11 The control methods also include: The first cylinder block unit 31 performs the exhaust stroke, and the second cylinder block unit 32 performs the intake stroke, expelling the gas from the first combustion chamber 311a and the second buffer chamber 321b, and filling the second combustion chamber 321a with gas. Specifically, the crank unit 41 continues to rotate clockwise. During the clockwise rotation of the crank unit 41 from 540° to 720°, the first piston 312 moves from the bottom dead center to the top dead center position within the first cylinder liner 311, and the second piston 322 moves from the top dead center to the bottom dead center position within the second cylinder liner 321. That is, the first cylinder block unit 31 of the power generation device is in the exhaust stroke stage, and the second cylinder block unit 32 is in the intake stroke stage.

[0113] In this embodiment, during the exhaust stroke and intake stroke of the second cylinder unit 32, the control module 5 can also control the opening of the first exhaust component 3112, allowing external air to enter the first buffer chamber 311b and preventing negative pressure from being generated in the first buffer chamber 311b, which would affect the first piston 312 in expelling the exhaust gas from the first combustion chamber 311a. Simultaneously, during the intake stroke of the second cylinder unit 32, the control module 5 controls the opening of the second exhaust component 3212 to expel the gas in the second buffer chamber 321b to the atmosphere, reducing the resistance encountered by the second piston 322 as it travels within the second cylinder liner 321. This allows the second cylinder unit 32 to smoothly complete its intake stroke, ensuring that the first cylinder unit 31 can smoothly expel the exhaust gas from the first combustion chamber 311a.

[0114] During the exhaust stroke of the first cylinder block unit 31 and the intake stroke of the second cylinder block unit 32, the connecting rod unit 33 drives the moving sub-module 2 to move from its rightmost end to its leftmost end along the axial direction of the stator module 1. The moving sub-module 2 cuts the magnetic field lines generated by the stator module 1 to generate an induced current, thereby generating electricity.

[0115] Thus, the first cylinder unit 31 and the second cylinder unit 32 of the power generation equipment both complete the entire four-stroke process of intake, compression, power, and exhaust. Subsequently, the first cylinder unit 31 and the second cylinder unit 32 can cooperate with each other to drive the mover module 2 to perform reciprocating linear motion within the stator module 1, so that the mover module 2 can continuously cut the magnetic field lines generated by the stator module 1 to generate induced current and achieve continuous power generation.
