[0036] A modular electric surfboard provided by the present application includes a surfboard module, a power module, and a battery module, wherein: the surfboard module includes a board body; the power module includes a mast assembly, a motor, a thruster, and an electronic speed control module. The power module is detachably connected to the surfboard module through one end of the mast assembly, and the other end of the mast is detachably connected to the electronic speed control module; the power supply module includes a battery, and the power supply module is detachably connected to the board body, and the battery is electrically connected to the motor. Due to the modular structure and the detachable interface design, it is simple, universal, convenient for loading, unloading and maintenance, and can realize the conversion of various surfing conditions and surfing modes.

[0037] As Figure 1 shown, it is a schematic diagram of the combined structure of the modular electric surfboard according to an embodiment of the present application, Figure 2 and is a schematic diagram of the exploded structure. As Figure 1 , Figure 2 shown, the surfboard module includes a board body 1, a battery compartment 11 is provided on the board body 1, the power supply module is detachably installed in the battery compartment 11, and a battery 2 is provided in the battery module. The power module includes a mast assembly, a motor 32, a thruster 33, and an electronic speed control module 34. The power module is detachably connected to the board body 1 of the surfboard module through one end of the mast 31, and the other end of the mast 31 is detachably connected to the electronic speed control module 34.

[0038] In this embodiment, the mast assembly includes a detachable 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 electronic speed control module 34. The connection between the mast assembly and the electronic speed control module 34 is achieved through the mast connector 37. Of course, the mast 31 and the mast connector 37 can also be integrated, or the connection between them is non-detachable, which can also achieve the purpose of this application.

[0039] In this embodiment, the detachable mast connector 37 includes a hydrofoil mounting base 370. 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 32, and the rear hydrofoil 36 is detachably mounted on the thruster 32. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly do not necessarily need to be provided at the same time. It can only include the front hydrofoil 35 or only the rear hydrofoil 36, and the function of this application can still be achieved. In addition, in the case where the front hydrofoil 35 is not installed, the hydrofoil mounting base 370 may not be provided on the mast connector 37, and the function of this application can still be achieved.

[0040] Furthermore, in this embodiment, the motor 32, the thruster 33, and the electronic speed control module 34 of the power module are all detachably connected. As Figure 3 shown, the first connection end 320 of the thruster 33 and the motor 32 are connected together by plugging. To ensure a firm connection, after plugging, they are connected and fixed by fixing screws. A sealing device can be provided at the plugging part to improve the sealing effect.

[0041] Furthermore, the thruster 33 further includes a propeller shaft 330, and the motor 32 includes a motor shaft 323. The motor shaft 323 of the motor 32 is connected to the propeller shaft 330 of the thruster 33 through a coupling 322. In another embodiment, the motor shaft 323 and the propeller shaft 330 can also be connected by other means, such as key connection. As can be seen from the Figure 4 connection schematic diagram, at the front end and the rear end of the thruster 33, the propeller shaft 330 is radially limited and fixed by bearings. A retaining ring is provided on one side of the bearing for axial limitation of the bearing. At the same time, at the front end and the rear end of the thruster 33 where the bearings are installed, sealing rings are provided. A cavity is formed between the two sealing rings on both sides, and sealing oil can be injected into the cavity to form a sealed cavity, which plays a role in waterproof protection for the motor 32.

[0042] Furthermore, the second connection end 321 of the electronic speed control device 34 and the motor 32 are connected together by plugging. In this embodiment, they are fixed by fixing screws. As Figure 5As shown, it is an enlarged schematic diagram of the structure of the connection between the motor 32 and the electronic speed control device 34. The second connection end 321 of the motor 32 includes a second electrical terminal 3211 and a second fixed interface 3212. The electronic speed control device 34 is provided with a third connection end 341, which includes a third electrical terminal 3411 and a third fixed interface 3412. Through the insertion of the second electrical terminal 3211 and the third electrical terminal 3411, electrical reliability and safety are achieved. Through the connection of the second fixed interface 3212 and the third fixed interface 3412, the detachable connection between the motor 32 and the electronic speed control device 34 is achieved. In this embodiment, the second fixed interface 3212 and the third fixed interface 3412 are of the plug-in type. In order to connect the motor 32 and the electronic speed control device 34 more quickly and safely, a connection guiding structure can also be provided on the second fixed interface 3212 or the third fixed interface 3412.

[0043] A schematic diagram of the structure of the board body and the mast of the modular electric surfboard is as Figure 6a shown, and a partial enlarged view of the connection structure is as Figure 7 shown. The board body 1 in this embodiment is a rigid board body. A board body base 10 is provided at the bottom of the board body 1. The mast 31 is provided with a mast base 311 connected to the board body base 10. A sealing ring 12 is provided between the board body base 10 and the mast base 311 and is fixed by screws 312. In fact, in addition to the threaded connection method in the embodiment, other detachable connections between the board body base 10 and the mast base 311, including but not limited to one or several of snap connection, pin connection, key connection, tooth connection, and ferrule connection, can all achieve the purpose of this application and make the loading and unloading convenient.

[0044] Furthermore, the power module includes at least two masts 31. When the length, tilt angle, etc. of the masts 31 change, the surfing mode will change accordingly, which can meet the needs of different experiences. For the electric surfboard in the embodiment of this application, due to the modular structure, different masts 31 can be assembled, and different needs can be met at the lowest cost.

[0045] In this embodiment, as Figure 6b 、 6c 、6d shown, the masts 31 have different structural designs. The length and / or tilt angle of each mast 31 is different, and it can be set as a long rod, a short rod, a straight rod, or an inclined rod. However, the mast bases 311 in different masts 31 have the same structure and can all be connected to the board body base 10 of the board body 1 to achieve the replaceable use of the masts 31, which is convenient for the electric surfboard to achieve different modes. For example, in the embodiment of this application, a longer mast 31 can be selected for surfing, or a shorter mast 31 can be selected to achieve water surface gliding.

[0046] Further, the other end of the mast 31 is detachably connected to the electronic speed control module 34. The electronic speed control module 34 includes a wire harness. The wire harness passes through the mast 31 and is connected to the battery 2. Then, through the connection between the second electrical terminal 3211 and the third electrical terminal 3411, the electrical connection between the battery 2 and the motor 32 is achieved.

[0047] Further, in order to have good waterproof and heat dissipation effects, in this embodiment, the electronic speed control module 34 can be sealed by means such as potting with sealant, sealing grooves, and sealing gaskets. The electronic speed control module 34 has a metal shell. The electronic speed control module 34 itself is potted with sealant, having a good watertight effect. After installation, the whole can no longer be waterproofed. With a metal shell, after assembly, it becomes an integral part with the motor 32 and is placed underwater together with the motor 32, directly contacting the water, having a good heat dissipation effect.

[0048] In the embodiment of the present application, the electronic speed control module 34 is combined with the motor 32, the hydrofoil assembly, and the mast 31 through a detachable structure through simply and uniformly designed electrical and structural interfaces, facilitating disassembly, assembly, maintenance, and modular upgrade. The shell of the electronic speed control module 34 and the installation structures of the motor 32 and the hydrofoil assembly adopt an integrated design, having a good fluid shape.

[0049] Further, the power system of the present application can be provided with a hydrofoil assembly or can be without a hydrofoil. In order to cooperate with the installation of the hydrofoil assembly, as Figure 8a 、 8b shown, the mast connector 37 can also have different settings. Figure 8a As shown in Figure 8b is the mast connector 371 provided with a hydrofoil mounting base 370, and Figure 9 、 Figure 10 shown, in this embodiment, when connecting the front hydrofoil 35, the mast connector 371 provided with a hydrofoil mounting base 370 is adopted. 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. The rear hydrofoil 36 is detachably mounted on the thruster 33 by screws. In actual use, the front hydrofoil 35 and the rear hydrofoil 36 of the hydrofoil assembly do not necessarily need to be provided at the same time. It can include only the front hydrofoil 35 or only the rear hydrofoil 36, and still be able to achieve the functions of the present application.

[0050] Further, in order to achieve multiple mode conversions, in this embodiment, the hydrofoil assembly includes at least two groups. At least one of the shapes, sizes, and installation angles of the at least two groups of hydrofoil assemblies is different. The installation methods of the two groups of hydrofoil assemblies with the hydrofoil mounting base 370 and the thruster 33 are the same for easy replacement. Similar to the change in the specifications of the mast 31, different selections of hydrofoils will also bring new feelings in the surfing mode.

[0051] The electric surfboard using the embodiment of the present application can change the motion mode. Figure 11a 、 11b It is a schematic structural diagram of an electric surfboard in different modes after combining and connecting different modular masts and power modules in the present application. As Figure 11a shown, a longer mast 31 can be connected to the board body 1, and hydrofoils with adapted specifications can be installed on the thruster 33 and the electronic speed controller device 34 to achieve the hydrofoil power mode. Also, the power in a certain mode can be changed by replacing hydrofoil assemblies with different specifications, using thrusters 33 of different types or different specifications, and then the surfing mode can be adjusted. Or, as Figure 11b shown, a shorter mast 31 can be selected to change the hydrofoil surfing mode to a gliding surfing mode of skimming on the water surface, meeting the requirements of different usage scenarios. In short, since the connection methods of these modules adopt a general design, as many replacement modes as possible can be achieved without excessively increasing the number of modules, which is convenient for carrying and loading / unloading, and will not increase too much usage cost.

[0052] As Figure 12 shown, it is another preferred embodiment of the present application. 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, for improving safety, handrails 5 are also provided and installed on the inflatable board body in this embodiment. 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 types of thrusters 33. In fact, due to the general connection method of this embodiment, the electric surfboard of the present application can be configured with different board bodies to meet various needs of users.

[0053] The modular electric surfboard of the present application has modular components and their detachable interface structures. The interface structure adopts a simple and general interface structure. On the one hand, it is convenient for assembly and disassembly, and the use is more convenient. At the same time, since each component is designed as an independent module and each module adopts a simple general interface design, some components including hydrofoil assemblies, masts, board bodies, motors, thrusters, electronic speed controllers, etc. can be replaced with different models, enabling the modular electric surfboard of the present application to achieve conversions of various surfing conditions and surfing modes.
