It should be noted that the embodiments of the present application are merely illustrative of one or more implementations of the present application and are not intended to limit the present application. Simple variations similar to these embodiments made by those skilled in the art are all within the scope of protection of this application.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0043] This application provides a modular power system, including a motor 32, a thruster 33, an electronic speed controller (ESC) module 34, and a mast assembly. The motor 32 includes a first connecting end and a second connecting end. The first connecting end of the motor 32 is detachably connected to the thruster 33, and the second connecting end of the motor 32 is detachably connected to the ESC module 34. The mast assembly is detachably connected to the ESC module 34. Due to its modular structure and detachable interface design, this modular power system is easy to install, remove, and maintain. Modular electric surfboards using this modular power system can switch between various surfing conditions and surfing modes.

[0044] Figure 1 shows an exploded view of a modular power system according to an embodiment of this application. As shown in Figure 1, the modular power system includes a mast assembly, a motor 32, a thruster 33, and an electronic speed controller (ESC) module 34. The mast assembly is connected to the ESC module 34, and the motor 32, thruster 33, and ESC module 34 are all detachably connected. In this embodiment, the mast assembly includes a detachably connected mast 31 and a mast connector 37. The mast connector 37 includes a first connecting end and a second connecting end. The first connecting end of the mast connector 37 is detachably connected to the mast 31, and the second connecting end of the mast connector 37 is detachably connected to the ESC module 34. Of course, the mast 31 and the mast connector 37 can also be integral or non-detachably connected, which can also achieve the purpose of this application.

[0045] In this embodiment, the detachable mast connector 37 includes a hydrofoil mounting base 370, and the modular power system further includes a hydrofoil assembly. The hydrofoil assembly includes a front hydrofoil 35 and a rear hydrofoil 36. The front hydrofoil 35 is detachably mounted on the hydrofoil mounting base 370 of the mast connector 37, and the rear hydrofoil 36 is detachably mounted on the thruster 33. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly are not necessarily provided simultaneously; only the front hydrofoil 35 or only the rear hydrofoil 36 may be included, and the functions of this application can still be achieved. Furthermore, if the front hydrofoil 35 is not installed, the mast connector 37 without the hydrofoil mounting base 370 can be used, and the functions of this application can still be achieved.

[0046] Figure 2 shows a connection diagram of a modular power system according to an embodiment of this application. The first connection end 320 of the thruster 33 and the motor 32 are connected together by a plug-in method. In order to ensure a firm connection, the plug-in is fixed by fixing screws. The plug-in is provided with a double sealing ring to improve the sealing effect.

[0047] Furthermore, the motor 32 includes a coupling 323, and the propeller 33 includes a propeller shaft 330. The coupling 323 of the motor 32 is connected to the propeller shaft 330 of the propeller 33 via a coupling 322. In another embodiment, the coupling 323 and the propeller shaft 330 can also be connected in other ways, such as by a key. As can be seen from the connection diagram in Figure 3, the propeller shaft 330 is radially limited and fixed at the front and rear ends of the propeller 33 by bearings. A retaining ring is provided on one side of the bearing to axially limit the bearing. At the same time, sealing rings are provided at the bearing mounting locations at the front and rear ends of the propeller 33. A cavity is formed between the sealing rings on both sides, and sealing oil can be injected into the cavity to form a sealed cavity, which provides waterproof protection for the motor 32.

[0048] The plug-in structure of the power module used in this embodiment is not only convenient and quick, but also transforms the rotary seal of the motor 32 into a static seal, reducing the motor 32's dependence on dynamic sealing elements and improving reliability. The thruster 33 and the motor 32 are connected by a male-female plug-in method, and then secured with screws after mating. A double-layer sealing ring is provided at the plug-in point, effectively providing a seal. The motor 32, as a rotary drive component, is connected to the propeller shaft via a coupling 323. Bearings radially limit and fix the propeller shaft at the front and rear ends of the thruster 33. A retaining ring is provided on one side of each bearing to axially limit its movement. Simultaneously, a skeleton sealing ring is provided at the bearing mounting points at the front and rear ends of the thruster 33, forming a cavity between the sealing rings on both sides. The cavity is filled with sealing oil, forming a sealed chamber that effectively prevents external water from entering, providing waterproof protection for the rotating side of the motor.

[0049] Furthermore, the second connection end 321 of the ESC module 34 and the motor 32 are connected together by a plug-in method and fixed with fixing screws. Figure 4 shows a schematic diagram of the connection between the second connection end 321 of the motor 32 and the ESC module 34. The second connection end 321 of the motor 32 includes a second electrical terminal 3211 and a second fixed interface 3212. The ESC module 34 has a third connection end 341, including a third electrical terminal 3411 and a third fixed interface 3412. Electrical reliability and safety are achieved through the plug-in connection of the second electrical terminal 3211 and the third electrical terminal 3411. A detachable connection between the motor 32 and the ESC module 34 is achieved through the connection of the second fixed interface 3212 and the third fixed interface 3412. In this embodiment, the second fixed interface 3212 and the third fixed interface 3412 are plug-in. For faster and safer connection between the motor 32 and the ESC module 34, a connection guide structure can also be provided. The ESC module 34 achieves electrical reliability of the mating terminals through its electrical terminal and guide structure design; ensuring plug-and-play functionality while also guaranteeing safe and reliable electrical mating. As shown in Figure 4, the mating interface between the ESC module 34 and the motor 32 is also equipped with a double-layer sealing ring, ensuring a good watertight environment for the mating terminals after mating.

[0050] Figures 5a and 6 show schematic diagrams of the mast structure of the modular power system. The figures illustrate the connection between the mast 31 and the board body 1 when the power system is used in a modular electric surfboard. The mast 31 has a mast base 311 for connecting to the board body 1 during assembly of the modular electric surfboard. In this embodiment, the mast base 311 is an integral structure. In a preferred embodiment, the mast base 311 can be detachable. This allows for connection to different board bodies 1 with different connection structures using only different mast bases 311, further expanding the application range of the modular power system.

[0051] Of course, the connection between the mast base 311 and the board body 1 of the modular electric surfboard, and the detachable connection between the mast 31 and the mast base 311, including but not limited to one or more of the following: threaded connection, snap-fit ​​connection, pin connection, key connection, toothed connection, sleeve connection, etc., can all achieve the purpose of this application and make loading and unloading convenient.

[0052] Furthermore, the mast assembly includes at least two masts 31. As shown in Figures 5a-5d, this embodiment includes four types of masts 31. Each mast 31 has one or more different characteristics, such as length and tilt angle. However, the mast base 311 of the different masts 31 has the same structure and can be detachably connected to the surfboard body 1 to achieve interchangeable use of the masts 31. When the length, tilt angle, etc. of the mast 31 change, the surfing mode will change accordingly, enabling the modular electric surfboard to meet different experience needs with different modes. Due to its modular structure, the modular electric surfboard of this embodiment can be assembled using different masts 31, meeting different needs with minimal cost.

[0053] In this embodiment, as shown in Figures 5b, 5c, and 5d, the masts 31 have different structural designs. Each mast 31 has a different length and / or tilt angle, and can be configured as a long rod, a short rod, a straight rod, or an angled rod. However, the mast base 311 in different masts 31 has the same structure, as shown in Figure 6, and can all be connected to the board base 10 to achieve interchangeable use of the masts 31, facilitating different modes of the modular electric surfboard. For example, in this embodiment, a longer mast 31 can be selected for surfing, as shown in Figures 5a, 5b, and 5c, or a shorter mast 31 can be selected, as shown in Figure 5d, to achieve gliding close to the water surface.

[0054] Furthermore, the other end of the mast 31 is detachably connected to the ESC module 34, which includes a wiring harness that passes through the mast 31 and is connected to the battery. The battery is then electrically connected to the motor 32 through the connection of the second electrical terminal 3211 and the third electrical terminal 3411.

[0055] To achieve good waterproofing and heat dissipation, in this embodiment, the ESC module 34 can be sealed using methods such as potting with sealant, sealing grooves, or sealing gaskets. The ESC module 34 has a metal casing. The ESC module 34 itself is potted with sealant, providing excellent watertightness, eliminating the need for further waterproofing. The metal casing, after installation, integrates it with the motor 32, allowing it to be placed underwater together with the motor, directly contacting the water and thus providing excellent heat dissipation.

[0056] In this embodiment, the ESC module 34, through a simple and unified electrical and structural interface, is detachably combined with the motor 32, hydrofoil assembly, and mast 31, facilitating disassembly, assembly, maintenance, and modular upgrades. The housing of the ESC module 34 is integrated with the motor 32 and hydrofoil assembly mounting structure, resulting in a good aerodynamic profile.

[0057] Furthermore, the power system of this application may or may not include a hydrofoil assembly. To facilitate the installation of the hydrofoil assembly, as shown in Figures 7a and 7b, the mast connector 37 can also have different configurations. Figure 7a shows a mast connector 371 with a hydrofoil mounting base 370, and Figure 7b shows a mast connector 372 without the hydrofoil mounting base 370. The hydrofoil assembly includes a front hydrofoil 35 and a rear hydrofoil 36. As shown in Figures 8 and 9, in this embodiment, when connecting the front hydrofoil 35, a mast connector 371 with a hydrofoil mounting base 370 is used. The front hydrofoil 35 has a hydrofoil mounting surface 351, and the hydrofoil mounting surface 351 and the hydrofoil mounting base 370 are fixed with screws. The rear hydrofoil 36 is detachably mounted on the propeller 33 with screws. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly do not necessarily need to be installed simultaneously; it may only include the front hydrofoil 35 or only the rear hydrofoil 36, still achieving the functions of this application.

[0058] Furthermore, to enable multiple mode switching, this embodiment includes at least two sets of hydrofoil assemblies. At least two sets of hydrofoil assemblies differ in shape, size, and installation angle. Both sets of hydrofoil assemblies are installed in the same way with the hydrofoil mounting base 370 and the propeller 33 for easy replacement. Similar to the variations in the mast 31's specifications, different hydrofoil selections will also bring new surfing experiences.

[0059] Figures 11a and 11b are schematic diagrams of two usage states of an electric surfing system according to an embodiment of this application. As shown in Figures 11a and 11b, since the power system has masts 31 of different specifications, a longer mast 31 can be connected to the board 1 according to usage requirements, and hydrofoils of appropriate specifications can be installed on the propeller 33 and the ESC module 34 to realize the hydrofoil power mode, as shown in Figure 11a; the power of a certain mode can also be changed by replacing hydrofoil components of different specifications and using different types or specifications of propellers 33, thereby adjusting the surfing mode; different specifications of masts 31 can also be selected, as shown in Figure 11b, by selecting a shorter mast 31 and removing the hydrofoil components, so that the hydrofoil surfing mode is changed to a gliding surfing mode that skims the water, meeting the needs of different usage scenarios.

[0060] In summary, because these modules use a universal connection design, they can achieve as many replacement modes as possible without increasing the number of modules excessively. They are easy to carry and install / remove, and do not increase the cost of use too much, thus meeting a variety of user needs.

[0061] An embodiment of this application provides a modular electric surfboard, including a surfboard module, a modular power system as described above, and a power supply module.

[0062] Surfboard module, including board body 1;

[0063] The modular power system is detachably connected to the surfboard module at one end of the mast assembly and detachably connected to the ESC module 34 at the other end of the mast assembly.

[0064] The power module includes a battery 2, which is detachably connected to the board 1. The battery 2 is electrically connected to the motor 32.

[0065] Because the modular electric surfboard of this application embodiment has a modular structure and adopts a detachable interface design, it is simple, universal, easy to install, remove and maintain, and can realize the conversion of various surfing conditions and surfing modes.

[0066] The board 1 is a rigid board or an inflatable board. The bottom of the board 1 is provided with a board base 10 connected to the mast 31. The mast 31 is provided with a mast base 311 connected to the board base 10.

[0067] The connection between the plate base 10 and the mast base 311 is a detachable connection. The detachable connection is not limited to one or more of the following: threaded connection, snap-fit ​​connection, pin connection, key connection, toothed connection, and ferrule connection.

[0068] It also includes handrails, which are detachably connected to the panel 1.

[0069] Figure 10 shows a schematic diagram of a modular electric surfboard assembly structure according to an embodiment of this application, and Figure 1 is an exploded structural diagram. As shown in Figures 10 and 13, the surfboard module includes a board body 1, a battery compartment 11 is provided on the board body 1, a power module is detachably installed in the battery compartment 11, and a battery 2 is provided inside the power module.

[0070] Figure 10 shows a schematic diagram of an embodiment of a modular electric surfboard using the modular electric system of this application. As shown in Figure 10, the connected modular power system is connected to the board body 1 via a mast 31. The board body 1 is provided with a battery compartment 11, which contains a battery 2. The wiring harness of the electronic speed control module 34 passes through the mast 31 and is connected to the battery 2. The battery 2 is then electrically connected to the motor 32 via the connection of the second electrical terminal 3211 and the third electrical terminal 3411.

[0071] Figure 12 shows another preferred embodiment of this application. To meet the needs of different surfers, the surfboard module's board body 1 is an inflatable board body, with a battery compartment 11 mounted on it. For enhanced safety, a handrail 5 is also installed on the inflatable board body in this embodiment. Of course, during use, the electric surfboard with the inflatable board body can still achieve different surfing modes by replacing different masts 31, hydrofoil components, or even different propellers 33. In fact, since the connection method in this embodiment is universal, the electric surfboard of this application can be configured with different board bodies to meet various user needs.

[0072] Figure 5a shows a schematic diagram of the modular electric surfboard's board body and mast, and Figure 6 shows a partial enlarged view of the connection structure. In this embodiment, the board body 1 is a rigid board body, with a board body base 10 at the bottom. The mast 31 has a mast base 311 connected to the board body base 10, and a sealing ring 12 is provided between the board body base 10 and the mast base 311, which are fixed by screws 312. In fact, besides the threaded connection method in this embodiment, other detachable connections can be used between the board body base 10 and the mast base 311, including but not limited to one or more of the following: snap-fit ​​connection, pin connection, key connection, toothed connection, and sleeve connection. All of these can achieve the purpose of this application and make loading and unloading convenient.

[0073] The modular electric surfboard of this application has modular components and a detachable interface structure. The interface structure adopts a simple and universal interface structure, which facilitates assembly and disassembly and makes it more convenient to use. At the same time, since each component is designed as an independent modular unit and each modular unit adopts a simple universal interface design, some components, including hydrofoil components, mast 31, board body 1, motor 32, propeller 33, ESC module 34, etc., can be replaced with different models, so that the modular electric surfboard of this application can realize the conversion of various surfing conditions and surfing modes.
