Description

Technical field

[0001] The present invention relates to the field of a generator, in particular a permanent magnet radial engine. State of the art

[0002] In recent years, efficient, clean energy conversion technology has become a hotspot of research, driven by continuously increasing energy demand and ever-stricter environmental protection requirements. Traditional combustion engines depend on burning fossil fuels and suffer from problems such as low efficiency and high pollution. Furthermore, while conventional electric motors offer higher efficiency, their large size and high cost still limit their applicability in high-torque, low-speed applications. Therefore, the development of an efficient, clean, and innovative drive system has become a critical area requiring further research and breakthrough.

[0003] The traditional combustion engine depends on fossil fuels and suffers from problems such as low energy efficiency, high pollution, and the depletion of non-renewable resources. Furthermore, while existing electric motors and battery technologies have alleviated the energy consumption problem to some extent, they still face numerous challenges: Currently widespread energy storage devices such as lithium iron phosphate batteries and ternary lithium batteries, although already used in areas like electric vehicles and ships, have limited energy density, short ranges, and long charging cycles, making them particularly unsuitable for deep-sea shipping and similar applications.

[0004] Although electrical and magnetic energy are interdependent physical phenomena, the development of energy technology has historically focused more on the development of electrical energy, while research into the direct use of permanent magnet energy has been relatively delayed, even neglected. Some currently existing magnetic drive devices (such as permanent magnet linear motors and magnetic couplers) often rely on electromagnets or a complex control system, resulting in a complicated structure and lower energy efficiency, making it difficult to achieve an efficient and stable output of mechanical energy. Disclosure of the invention

[0005] The present invention aims to solve at least one of the technical problems present in existing technology. To this end, one objective of the present invention is to provide a permanent magnet radial engine.

[0006] The technical solution of the present invention is as follows: A permanent magnet radial engine, characterized in that it comprises: a frame, a crankshaft, an electric starting module, a permanent magnet drive module and an electrical energy output module; that the crankshaft is designed to rotate on the frame; that the permanent magnet drive module comprises a first magnet, a second magnet and a connecting rod, the first magnet is rotatable relative to the frame, the second magnet is slidable relative to the frame, the second magnet is directly opposite the first magnet, the connecting rod is rotatably connected to the second magnet at one end and rotatably connected to the crankshaft at the other end; that at least one permanent magnet drive module is present, several permanent magnet drive modules are distributed around an axis of the crankshaft in a circumferential direction, if several permanent magnet drive modules are present to form a star-shaped topological connection; that the electric start module is connected to all permanent magnet drive modules to drive the first magnet to rotate circumferentially in the permanent magnet drive modules; that in the permanent magnet drive module, the first magnet can attract and repel the second magnet once per revolution, and the second magnet can slide back and forth under the cyclical attraction and repulsion in order to push the crankshaft to rotation via the connecting rod; that the crankshaft is connected to the power output module to drive the power output module to output the power energy, with a small part of the output power supplying the electric start module, and a remainder supplying an external load.

[0007] In comparison with the existing technology, the advantageous effects of the present invention are as follows: 1. A direct conversion mechanism of the magnetic field and mechanical energy. The first magnet and the second magnet interact cyclically, so that the second magnet generates a back-and-forth linear motion which is converted by the connecting rod into a rotary motion of the crankshaft, enabling contactless energy transfer and reducing the loss of friction and noise of operation. 2. A star-shaped, topological, synergistic drive using multiple magnets. Several permanent magnet drive modules are distributed radially around the crankshaft, forming a star-shaped topological structure. Each module independently drives the crankshaft through the magnetic field effect of "repulsion due to similarity and attraction due to dissimilarity." In combination with an output torque, the power density and efficiency are significantly increased, which has potential applications in fields such as renewable energy power generation, vehicle and ship propulsion, and deep-sea navigation.

Obviously, the described embodiments are only part of the embodiments of the present invention and not the entirety of them. All other embodiments that could be obtained by a person skilled in the art without inventive effort based on the embodiments specified in the present invention fall within the scope of protection of the present invention.

[0012] The embodiments of the present invention are described in detail below. Schematic examples of these embodiments are illustrated in the figures, where identical or similar designations from beginning to end represent the same or similar elements or elements with the same or similar function. In the description of the embodiment of the present invention, it is understood that the directional and positional relationships indicated by the terms "above," "below," "front," "behind," "left," "right," "inside," "outside," "vertical," "circumferential direction," etc., refer to the directional and positional relationships depicted in the figures.This serves only to facilitate the presentation of the present invention and to simplify the description, instead of indicating or suggesting that the referred devices or components have a certain direction, must be constructed and operated in a certain direction, and therefore cannot be understood as a limitation of the present invention.

[0013] In the description of the embodiments of the present invention, the terms "arranged," "connected," "connection," and "fastening" shall be understood in a general sense, unless explicitly prescribed and limited otherwise. For example, it may be a fixed connection, a detachable connection, or a connection as a whole; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium or an internal connection between two components.

Furthermore, the terms "first," "second," "third," etc., are used solely for the purpose of distinguishing the features and should not be interpreted as indicating or suggesting relative importance. Therefore, the feature limited by "first" or "second" may explicitly or implicitly encompass one or more of the features.

[0015] The following is related to Fig. until Fig. a permanent magnet radial engine according to the embodiments of the present invention is described, comprising: a frame 1, a crankshaft 2, an electric starting module 3, a permanent magnet drive module 4 and an electrical energy output module 5.

[0016] The crankshaft 2 is provided to rotate on the frame 1; the permanent magnet drive module 4 comprises a first magnet 41, a second magnet 42 and a connecting rod 43, the first magnet 41 is rotatable relative to the frame 1, the second magnet 42 is slidable relative to the frame 1, the second magnet 42 is directly opposite the first magnet 41, the connecting rod 43 is rotatably connected at one end to the second magnet 42, and rotatably connected at the other end to the crankshaft 2; At least one permanent magnet drive module 4 is present; if several permanent magnet drive modules are present, several permanent magnet drive modules 4 are distributed circumferentially around an axis of the crankshaft 2 to form a star-shaped topological connection; the electrical starting module 3 is connected to all permanent magnet drive modules 4 to drive the first magnet 41 to rotate circumferentially in the permanent magnet drive modules 4.

[0017] In the permanent magnet drive module 4, the first magnet 41 can attract and repel the second magnet 42 once per revolution, the second magnet 42 can slide back and forth under the cyclic attraction and repulsion in order to push the crankshaft 2 to rotation via the connecting rod 43.

[0018] This means that in the present device, using the magnetic field principle of "repulsion due to similarity and attraction due to dissimilarity," the second magnet 42 is driven to slide back and forth, thus representing a cyclic piston movement. The connecting rod 43 then drives the crankshaft 2 into rotation, converting magnetic energy into mechanical energy. Additionally, several permanent magnet drive modules form a star-shaped topological connection, thus driving the same crankshaft 2 into rotation, with the respective modules synergistically driving the same crankshaft 2. In combination with an output torque, the power density and efficiency are significantly increased, and the modular design facilitates the expansion of the performance range.

[0019] The crankshaft 2 is connected to the electrical energy output module 5 to drive the electrical energy output module 5 to output the electrical energy, with a small part of the output electrical energy supplying the electric start module 3, and a remainder supplying an external load, thereby enabling a closed self-circulation of a circuit ring of the entire system, and the core value application of converting the magnetic energy of the permanent magnet drive module 4 into electrical energy for external output can be more adequately represented.

[0020] In some embodiments, such as in Fig. - Fig. As shown, the electric start module 3 comprises a power source, a low-speed motor 31, a reduction gearbox 32, a first pulley 33, a second pulley 34, a first drive belt 35, a center bevel gear 36 and a planetary bevel gear set; The power source is connected to the low-speed motor 31, which is connected to the reduction gear 32. The first pulley 33 is provided on an output shaft of the reduction gear 32. The center bevel gear 36 is provided to rotate on the frame 1. The second pulley 34 is fixed coaxially on the center bevel gear 36. The first pulley 33 and the second pulley 34 are connected by the first drive belt 35. Around the circumference of the center bevel gear 36, several planetary bevel gear sets are provided, each corresponding to the permanent magnet drive modules 4. Each planetary bevel gear set comprises a drive rod 37, a first drive bevel gear 38, and a second drive bevel gear 39. A driven bevel gear 45 is provided coaxially on the first magnet 41. The drive rod 37 is provided to rotate on the frame 1. The first drive bevel gear 38 is provided at one end of the drive rod 37, and the second drive bevel gear 39 is provided at the other end. The first drive bevel gear 38 is engaged with the center bevel gear 36, and the second drive bevel gear 39 is engaged with the driven bevel gear 45.

[0021] This allows a relatively strong torque to be output after the low-speed motor 31 is started by the power source via the reduction gear 32. Then, by transmitting the first pulley 33 and the second pulley 34, the center bevel gear 36 is first driven to rotate. After the rotation of the center bevel gear 36, the rotation of the first magnet 41 in the circumferential direction in the respective permanent magnet drive modules can then be enabled by transmitting the planetary bevel gear set. The transmission ratio of such a bevel gear has accuracy, high efficiency, a compact structure, and reliable operation.

[0022] In some embodiments, such as in Fig. - Fig. As shown, the frame 1 comprises a top plate 11, a bottom plate 12 and a sleeve 13, the sleeve 13 is rigidly connected between the top plate 11 and the bottom plate 12, the crankshaft 2 is located inside the sleeve 13 and is rotatably connected to both the top plate 11 and the bottom plate 12, the first magnet 41 is located outside the sleeve 13 and is rotatably connected to both the top plate 11 and the bottom plate 12, the electric start module 3 is provided on a top surface of the top plate 11; On a sleeve wall of the sleeve 13, several guide tubes 14 corresponding to the first magnet 41 are provided, within whose sliding pieces 44, which can slide like pistons, are provided, on a surface of a side of the sliding piece 44 close to the first magnet 41 the second magnet 42 is provided, on a surface of a side of the sliding piece 44 close to the crankshaft 2 the connecting rod 43 is provided.

[0023] In some embodiments, the first magnet 41 is a cylindrical magnet; two magnetic poles are distributed opposite each other in their own radial direction, as in Fig.As shown, the surface of the radial side of the first magnet 41 is the N pole, and the surface of another side is the S pole. Therefore, during the circumferential rotation of the first magnet 41, the N pole and the S pole alternately approach the second magnet 42. The second magnet 42 is an arc-shaped magnet concentric to the cylindrical magnet. Two magnetic poles of the second magnet 42 are distributed opposite each other in a separate sliding direction. However, the magnetic pole of the second magnet 42 closest to the first magnet 41 remains unchanged and can therefore be attracted and repelled. In the present device, all components are formed in a frame-like manner using a non-metallic carbon fiber material. This eliminates magnetic impedance, reduces magnetic loss, and the carbon fiber components offer the advantages of high-temperature resistance, high tensile strength, and low weight.

[0024] In actual application, after rotating the crankshaft 2, the mechanical energy of the crankshaft 2 can be used to drive the load to generate the drive force. Alternatively, a generator 52 can be connected to output electrical energy. In this case, the electrical energy output module 5 includes the generator 52. As shown in the figures, a lower end of the crankshaft 2 protrudes from the base plate 12 and is connected to a drive wheel. The drive wheel is connected to an input shaft of the generator 52 via the acceleration structure 51. The acceleration provided by the acceleration structure 51 increases the rotational speed of the input shaft of the generator 52 to ensure normal power generation by the generator 51.

[0025] In summary, the present facility has the following features: 1. A direct conversion mechanism of the magnetic field and mechanical energy. The first magnet 41 and the second magnet 42 interact cyclically, so that the second magnet 42 generates a back-and-forth linear motion which is converted by the connecting rod into a rotary motion of the crankshaft 2, enabling contactless energy transfer and reducing the loss of friction and noise of operation. 2. A star-shaped, synergistic drive using multiple magnets. Several permanent magnet drive modules 4 are distributed radially around the crankshaft 2, forming a star-shaped topological structure. Each module independently drives the crankshaft 2 through the magnetic field effect of "repulsion due to similarity and attraction due to dissimilarity." In conjunction with an output torque, the power density and efficiency are significantly increased, which has potential applications in fields such as renewable energy power generation, vehicle and ship propulsion, and deep-sea navigation.

[0026] Although some of the embodiments of the present invention have already been shown and described, the person skilled in the art in the relevant field can understand that various changes, modifications, replacements and deformations of these embodiments, without deviation from the principle and purpose of the present invention, all fall within the scope of protection of the claims of the present invention.
