[0034] like Figure 1 As shown, it is a schematic diagram of the decomposition structure of a modular power system according to an embodiment of the present application. Figure 1 As shown, the modular power system includes a mast assembly, a motor 32, a propeller 33 and an electric adjustment module 34. The mast assembly is connected to the electric adjustment module 34, and the motor 32, the propeller 33 and the electric adjustment 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 connection end and a second connection end. The first connection end of the mast connector 37 is detachably connected to the mast 31, and the second connection end of the mast connector 37 is detachably connected to the electric adjustment module 34. Of course, the mast 31 and the mast connector 37 can also be integrated or the two can be non-detachably connected, which can also achieve the purpose of the present application.

[0035] In this embodiment, the detachable mast connector 37 includes a hydrofoil mounting base 370, and the modular power system also 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 32, and the rear hydrofoil 36 is detachably mounted on the propeller 32. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly are not necessarily provided at the same time, and only the front hydrofoil 35 or only the rear hydrofoil 36 may be provided, and the functions of the present application can still be achieved. In addition, in the case where the front hydrofoil 35 is not installed, the mast connector 37 without the hydrofoil mounting base 370 may be used, and the functions of the present application can still be achieved.

[0036] like Figure 2 As shown, it is a schematic diagram of the connection of the modular power system of an embodiment of the present application. As shown in the figure, the propeller 33 and the first connection end 320 of the motor 32 are connected together by plugging. In order to ensure a firm connection, they are fixed by fixing screws after plugging, and a double-layer sealing ring is provided at the plug-in to improve the sealing effect.

[0037] Furthermore, the motor 32 includes a motor shaft 323, and the propeller 33 includes a propeller shaft 330. The motor shaft 323 of the motor 32 is connected to the propeller shaft 330 of the propeller 33 through a coupling 322. In another embodiment, the motor shaft 323 and the propeller shaft 330 may also be connected in other ways, such as a key connection. Figure 3 As can be seen from the connection diagram, at the front and rear ends of the propeller 33, the propeller shaft 330 is radially limited and fixed by bearings, and a retaining ring is provided on one side of the bearing to limit the bearing axially. At the same time, sealing rings are provided at the front and rear ends of the propeller 33 where the bearings are installed. 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.

[0038] The power module plug-in structure used in the embodiment of the present application is not only convenient and fast, but also converts the rotary seal of the motor 32 into a static seal, reduces the dependence of the motor 32 on the dynamic sealing element, and improves reliability. The propeller 33 and the motor 32 are connected together by a male-female plug-in method, and are fixed by screw locking after docking. A double-layer sealing ring is provided at the plug-in position to effectively play a sealing role. As a rotating drive component, the motor 32 is connected to the propeller shaft through a coupling 323. At the front and rear ends of the propeller 33, the propeller shaft is radially limited and fixed by bearings, and there are retaining rings on one side of the bearing to limit the bearing axially. At the same time, at the front and rear end bearing installations of the propeller 33, a skeleton sealing ring is provided, and a sealing cavity is formed between the sealing rings on both sides. Further, the cavity is filled with sealing oil to form a better sealing cavity, which effectively prevents external water from entering and plays a waterproof protection role for the rotating side of the motor.

[0039] Furthermore, the electric adjustment module 34 and the second connection end 321 of the motor 32 are connected together by plugging and fixed by fixing screws. Figure 4 As shown, it is a schematic diagram of the connection between the second connection end 321 of the motor 32 and the electric adjustment module 34.

The electrical reliability and safety are achieved by plugging the second electrical terminal 3211 and the third electrical terminal 3411. The detachable connection between the motor 32 and the electric adjustment module 34 is achieved by connecting 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. In order to connect the motor 32 and the electric adjustment module 34 more quickly and safely, a connection guide structure may also be provided. The electric adjustment module 34 achieves electrical reliability of the plug-in terminal through the design of the electrical terminal and the guide structure; while ensuring plug-and-play, it also ensures the safety and reliability of electrical plug-in. As shown Figure 4 In the figure, a double-layer sealing ring is also provided on the plug-in interface between the electric adjustment module 34 and the motor 32, which can ensure that the plug-in terminals have a good watertight environment after plugging in.

[0040] Figure 5, Figure 6 , which is a schematic diagram of the structure of the modular power system mast. The figure shows the connection relationship between the mast 31 and the board body 1 when the power system is used for an electric surfboard. The mast 31 is provided with a mast base 311, which is used to connect with the board body 1 of the electric surfboard when assembling the electric surfboard. In this embodiment, the connecting plate base 311 of the mast 31 is an integrated structure. In a preferred embodiment, the mast base 311 can be configured to be detachable, so that when the mast base 311 is connected to different board bodies 1, if the connection structures are different, only different mast bases 311 need to be configured to achieve connection with different board bodies 1, which can further expand the application scope of the modular power system.

[0041] Of course, the connection between the mast base 311 and the surfboard body 1, and the detachable connection between the mast 31 and the mast base 311, including but not limited to one or more of threaded connection, snap connection, pin connection, key connection, tooth connection, and sleeve connection, can achieve the purpose of this application and make loading and unloading convenient.

[0042] Further, the mast assembly includes at least two masts 31, Figure 5a-5dAs can be seen, in this embodiment, four types of masts 31 are included, and one or more characteristics of the length and tilt angle of each mast 31 are different. However, the mast bases 311 in different masts 31 are of the same structure and can be detachably connected to the board body 1 of the surfboard to achieve replaceable use of the mast 31 and realize different modes of the electric surfboard.

[0043] In this embodiment, Figure 5b , 5c, 5d, for masts 31 of different structural designs, the length and / or inclination angle of each mast 31 is different, and it can be set as a long rod or a short rod or a straight rod or an inclined rod, but the mast base 311 in different masts 31 is the same structure, such as Figure 6 As shown, they can all be connected to the board base 10 to achieve the interchangeable use of the mast 31, so that the electric surfboard can achieve different modes. For example, in the embodiment of the present application, a longer mast 31 can be selected, such as Figure 5a , 5b 5c for surfing, a shorter mast 31 may also be selected, such as Figure 5d As shown, gliding close to the water surface is achieved.

[0044] Furthermore, the other end of the mast 31 is detachably connected to the electric adjustment module 34. The electric adjustment module 34 includes a wiring harness, which passes through the mast 31 and is connected to the battery. The electrical connection between the battery and the motor 32 is then achieved through the connection between the second electrical terminal 3211 and the third electrical terminal 3411.

[0045] In order to achieve good waterproof and heat dissipation effects, in this embodiment, the electric adjustment module 34 can be sealed by means of sealant potting, sealing grooves, sealing gaskets, etc., and the electric adjustment module 34 is a metal shell. The electric adjustment module 34 itself is potted with sealant, which has a good watertight effect, and the whole does not need to be waterproofed; the metal shell is used, and after installation, it becomes one with the motor 32, and is placed underwater with the motor 32, and is in direct contact with water, which has a good heat dissipation effect.

[0046] In the embodiment of the present application, the electric adjustment module 34 is combined with the motor 32, the hydrofoil assembly, and the mast 31 through a detachable structure through a simple and uniformly designed electrical and structural interface, which facilitates disassembly, assembly, maintenance, and modular upgrade. The housing of the electric adjustment module 34 is integrated with the motor 32 and the hydrofoil assembly mounting structure, and has a good fluid appearance.

[0047] Furthermore, the power system of the present application may be provided with a hydrofoil assembly, or may not be provided with a hydrofoil. Figure 7a , 7b As shown, the mast connection member 37 can also have different settings. Figure 7aShown is a mast connector 371 with a hydrofoil mounting base 370, Figure 7b The mast connecting rod 372 does not include a hydrofoil mounting base 370. The hydrofoil assembly includes a front hydrofoil 35 and a rear hydrofoil 36. Figure 8 , Fig. 9 As shown, in this embodiment, when the front hydrofoil 35 is connected, a mast connector 371 provided with a hydrofoil mounting base 370 is used, the front hydrofoil 35 is provided with a hydrofoil mounting surface 351, the hydrofoil mounting surface 351 and the hydrofoil mounting base 370 are fixed by screws, and the rear hydrofoil 36 is detachably mounted on the propeller 33 by screws. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly are not necessarily provided at the same time, and only the front hydrofoil 35 or only the rear hydrofoil 36 may be included, and the functions of the present application can still be achieved.

[0048] Furthermore, in order to achieve multiple mode conversions, the hydrofoil assemblies in this embodiment include at least two groups, and at least one of the shapes, sizes and installation angles of the at least two groups of hydrofoil assemblies is different. The two groups of hydrofoil assemblies are installed in the same manner as the hydrofoil mounting base 370 and the propeller 33 to facilitate replacement.

[0049] like Fig.10 FIG. 1 is a schematic diagram of an electric surfboard using a modular electric system according to an embodiment of the present application. Fig.10 As shown, the connected modular power system is connected to the board body 1 through the mast 31. The board body 1 is provided with a battery compartment 11, which contains batteries. The wiring harness of the electric adjustment module 34 passes through the mast 31 and is connected to the battery. The electrical connection between the battery and the motor 32 is then achieved through the connection between the second electrical terminal 3211 and the third electrical terminal 3411.

[0050] Fig.11a , 11b Schematic diagram of two usage states of an electric surfing system according to an embodiment of the present application. As shown in the figure, since the power system has masts 31 of different specifications, a longer mast 31 can be connected to the board body 1 according to the use requirements, and hydrofoils of adapted specifications can be installed on the propeller 33 and the electric adjustment module 34 to realize the hydrofoil power mode, such as Fig.11a As shown; the power size in a certain mode can also be changed by replacing hydrofoil components of different specifications and using propellers 33 of different types or specifications to adjust the surfing mode; different specifications of masts 31 can also be selected, such as Fig.11b As shown in , a shorter mast 31 is selected, and the hydrofoil assembly is removed, so that the hydrofoil surfing mode is transformed into a gliding surfing mode of gliding close to the water, meeting the needs of different usage scenarios.

[0051] like Fig.12As shown, it is another preferred embodiment of the present application. In order to meet the needs of different surfers, the board body 1 of the surfboard module adopts an inflatable board body, and a battery compartment 11 is provided on the inflatable board body. At the same time, in order to improve safety, a handrail 5 is also provided in this embodiment and installed on the inflatable board body. Of course, during use, the electric surfboard with an inflatable board body can still obtain different surfing modes by replacing different masts 31, hydrofoil assemblies, or even different propellers 33.

[0052] In short, since the connection method of these modules adopts a universal design, as many replacement modes as possible can be achieved without increasing the number of modules too much, making it easy to carry and load and unload, and without increasing the cost of use too much, thus meeting the various needs of users.
