[0002] As we all know, surfing is a popular sport due to its thrilling nature and effective exercise. However, current traditional surfboards require the propulsion of waves to function, and they lose their functionality when there is no wind or the waves are small. Therefore, in order to enable surfing even in calm or small waves, some manufacturers have begun to develop and design electric surfboards.
[0003] Research has found that current electric surfboards generally include a board body and a jet pump, battery pack, and controller mounted on the board body. The battery pack powers the controller and jet pump, and the controller establishes a communication connection with the jet pump to control the start and stop of the drive components in the jet pump.
[0004] Existing traditional technologies still require a large number of power supply and control cables to be installed on the board. When the injection pump is installed on the board, the control cables establish a communication connection between the controller and the injection pump, and the power supply cables allow the battery pack to supply power to the controller and the injection pump to drive and control the injection pump. This method has the problems of complex cable connections, low reliability, and complex and costly subsequent maintenance and replacement. Utility Model Content

[0009] Furthermore, in the electric surfboard described in this utility model, the water outlet is located at the end of the spray pump away from the board body along the length direction of the board body.
[0010] Furthermore, in the electric surfboard of this utility model, the driving mechanism includes a motor and a propeller assembly. The propeller assembly is disposed in the first drainage channel, and the motor is connected to the propeller assembly for driving the propeller assembly to rotate.
[0011] Furthermore, in the electric surfboard described in this utility model, a second through hole is provided at the bottom of the first receiving groove, and the spray pump is provided with a second drainage channel including a water inlet and a water outlet, with the water inlet being positioned directly opposite the second through hole.
[0012] Furthermore, the electric surfboard of this utility model also includes a contour-following fixing member, which is disposed in the first receiving groove and detachably connected to the board body; wherein, the contour-following fixing member covers the spray pump to lock the position of the spray pump in the first receiving groove.
[0013] Furthermore, in the electric surfboard described in this utility model, the upper surface of the board body is recessed and forms a second receiving groove, and the battery pack is detachably disposed in the second receiving groove; wherein, the second receiving groove has a through cavity on the side near the first receiving groove, and the through cavity is connected to the first receiving groove and the second receiving groove respectively.

[0035] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0036] like Figures 1-8 As shown in this embodiment, the present invention designs an electric surfboard, which includes: a board body 1, a battery pack 3, and a jet pump 2. The jet pump 2 and the battery pack 3 are detachably mounted on the board body 1, and the jet pump 2 and the battery pack 3 are electrically connected through a conversion connector 4. Specifically, the jet pump 2 includes a pump body and a controller 5 and a drive mechanism 6 disposed in the pump body. The controller 5 is electrically connected to the drive mechanism 6 and is used to control the start and stop of the drive mechanism 6, thereby using the drive mechanism 6 to drive the electric surfboard to move, ensuring that the electric surfboard can surf normally in waters without wind and waves.
[0037] In the electric surfboard designed in this utility model, its power supply and electronic control scheme have been adjusted. No wiring is set in the board body 1, and the existing power supply wiring and control wiring set in the board body 1 have been eliminated. Instead, a direct electrical connection is established between the spray pump 2 and the battery pack 3 by setting a conversion connector 4, which reduces the difficulty of wiring connection when installing the spray pump 2 and the battery pack 3.
[0038] Meanwhile, the electric surfboard eliminates the control cable that is currently located in the board body 1. Instead, the controller 5 is directly integrated into the jet pump 2 to achieve a modular design for the jet pump 2. This means that the controller 5 in the jet pump 2 is directly used to control the drive mechanism 6 of the jet pump 2. After the jet pump 2 is installed on the board body 1, it does not need to be connected to any additional control cable. It only needs to connect its own power input connector 25 to the conversion connector 4 to work normally.
[0039] Accordingly, such as Figure 6 As shown, in order to provide users with a better experience and facilitate users to control the power output of the above-mentioned spray pump 2, in practical applications, a control button 7 can also be set on the pump body of the spray pump 2. It can be specifically set on the upper surface of the pump body, and the control button 7 is electrically connected to the controller 5 inside the pump body, so that the user can send control commands to the controller 5 by pressing the control button 7, thereby using the controller 5 to control and adjust the kinetic energy output of the drive mechanism 6.
[0040] It should be noted that, see Figure 3 and Figure 4 In this embodiment, in order to facilitate the user's installation of the spray pump 2 and the battery pack 3, a first receiving groove 11 is recessed and formed on the upper surface of one end of the plate 1 so that the spray pump 2 can be detachably disposed in the first receiving groove 11; at the same time, a second receiving groove 12 is also partially recessed and formed on the upper surface of the plate 1 so that the battery pack 3 can be detachably disposed in the second receiving groove 12.
[0041] As can be seen, unlike the existing traditional installation methods of the spray pump 2 and battery pack 3, in this utility model, the spray pump 2 and battery pack 3 can be installed in the corresponding receiving slots in an upper-mounted manner. This installation method determines that when users play on the water, if they need to disassemble the spray pump 2 and battery pack 3, they can directly pull out the spray pump 2 or battery pack 3 from the corresponding receiving slots on the upper surface of the plate 1. The installation and disassembly are simple, which can greatly reduce the difficulty of maintenance and replacement.
[0042] Accordingly, such as Figure 1 , Figure 2 As shown, in this embodiment, when the above-mentioned spray pump 2 is installed in the first receiving groove 11, the spray pump 2 is specifically located at the tail end of the electric surfboard. When the user steps on the upper surface of the board body 1 or the upper surface of the battery pack 3 of the electric surfboard, the tail end of the electric surfboard can be immersed in water. At this time, at least part of the spray pump 2 can be immersed in water, and the spray pump 2 is used to drive the electric surfboard to move.
[0043] To ensure that the spray pump 2 can work properly, such as Figure 4As shown, in this embodiment, a first through hole 13 is specifically opened at the bottom of the first receiving groove 11, and the spray pump 2 is provided with a first drainage channel including an inlet 21 and an outlet 22, so that the inlet 21 of the first drainage channel can be set directly opposite the first through hole 13; at this time, the outlet 22 of the first drainage channel can be opened at the end of the spray pump 2 away from the plate 1 along the length direction of the plate 1, that is, it can be specifically set at the tail end of the spray pump 2, so that the water flowing into the first drainage channel from the first through hole 13 and the inlet 21 is sprayed out from the outlet 22, thereby generating a counter-thrust force to move the plate 1.
[0044] A filter screen 26 can be installed at the water inlet 21 of the spray pump 2 to filter out larger debris in the water and prevent it from entering the drainage channel of the spray pump 2, thus preventing blockage.
[0045] like Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, in order to effectively drive the plate 1 to move, the driving mechanism 6 is specifically provided, including a motor 61 and a propeller assembly 62. The propeller assembly 62 can correspond to the first drainage channel, and the motor 61 can be connected to the propeller assembly 62 for driving the propeller assembly 62 to rotate, thereby driving the water flow of the first drainage channel to be sprayed out from the outlet 22 of the spray pump 2.
[0046] It should be noted that the motor 61 used in the jet pump 2 of a traditional electric surfboard often overheats due to prolonged operation. To avoid overheating, the electric surfboard designed in this invention includes a second drainage channel on the jet pump 2, comprising an inlet 23 and an outlet 24. A second through hole 14 is also provided at the bottom of the first receiving groove 11, with the inlet 23 of the second drainage channel directly opposite the second through hole 14 of the first receiving groove 11.
[0047] In practical applications, the space within the pump body can be divided to create two independent drainage channels: a first drainage channel and a second drainage channel, each performing different functions. The propeller assembly 62, located in the first drainage channel, rotates to drive water flow from the inlet 21 into the first drainage channel, which is then ejected from the outlet 22 of the spray pump 2, generating thrust to achieve the driving function. The second drainage channel within the spray pump 2 can be used for heat dissipation; the motor 61 can be specifically located within the second drainage channel, allowing the flowing water to carry away the heat generated by the motor 61 during operation. In practical applications, the space within the spray pump 2 can be divided into multiple chambers, such as a first chamber and a second chamber. The first drainage channel can be located in the first chamber, and the motor 61 can be specifically located in the second chamber. The inlet 23 of the second drainage channel can communicate with the second chamber, and the outlet 24 of the second drainage channel can communicate with the first chamber. In this case, the first drainage channel is a flow channel isolated separately within the first chamber by a flow guide shroud and is not connected to the first chamber. Figure 8 Although the structure shown does not demonstrate the connection between the first chamber and the second chamber, in practical applications, a through hole can be opened between the first chamber and the second chamber to allow water from the second chamber to be introduced into the first chamber and discharged from the drain outlet 24 connected to the first chamber.
[0048] It should be emphasized that, in this embodiment, in order to achieve heat dissipation of the motor 61 without affecting the water flow in the first drainage channel of the electric surfboard and avoid affecting the output power, the electric surfboard is specifically designed so that the first drainage channel and the second drainage channel are not connected, and the two channels have independent water inlet and outlet.
[0049] Accordingly, when water is ejected from the outlet 22 of the first drainage channel of the aforementioned spray pump 2, generating a counter-thrust to drive the electric surfboard of this invention to move, in order to ensure that the spray pump 2 does not detach from the first receiving groove 11 of the board body 1 due to the counter-thrust, in this embodiment, as follows: Figure 3 As shown, a contoured fastener 8 is also provided on the plate 1. The contoured fastener 8 adopts a contoured structure and is set in the first receiving groove 11 and locked to the plate 1 by screws. At this time, the contoured fastener 8 can be correspondingly covered on the spray pump 2 in the first receiving groove 11 and lock the position of the spray pump 2 in the first receiving groove 11 to prevent the spray pump 2 from loosening and shifting during operation.
[0050] In addition, another major feature of this utility model is that it uses a conversion connector 4 to replace the existing power supply cable set in the board body 1. The conversion connector 4 is easy to install and has strong connection reliability.
[0051] See Figure 5As shown, in this embodiment, in order to facilitate the installation of the above-mentioned conversion connector 4, a through cavity 15 is provided on the side of the second receiving groove 12 of the electric surfboard body 1 near the first receiving groove 11. The through cavity 15 is connected to the first receiving groove 11 and the second receiving groove 12 respectively, so that the above-mentioned conversion connector 4 can be disposed in the through cavity 15, and one end of the conversion connector 4 extends into the first receiving cavity and is electrically connected to the spray pump 2; at the same time, the other end of the above-mentioned conversion connector 4 extends into the second receiving cavity and is electrically connected to the battery pack 3.
[0052] Because the aforementioned conversion connector 4 is located in the through cavity 15 between the first receiving groove 11 and the second receiving groove 12, and its two ends are blocked by the pump body of the spray pump 2 and the battery pack 3 respectively, it is not easy for water to enter, thus improving the reliability and stability of the conversion connector 4. Furthermore, to further improve the sealing, a waterproof plate can be locked onto the upper surface of the battery pack 3 to prevent water from entering the second receiving groove 12.
[0053] See also Figure 5 As shown, in this embodiment, the aforementioned conversion connector 4 can specifically adopt an L-shaped structure design. The conversion connector 4 can specifically include a first connecting part 41 and a second connecting part 42, with the first connecting part 41 connected to the second connecting part 42 in an L-shaped structure. In this case, the first connecting part 41 can be used to connect to the power input structure of the pump 2 near the battery pack 3, and the second connecting part 42 can extend into the lower surface of the battery pack 3 and be electrically connected to a connector provided on the lower surface of the battery pack 3. The reason for controlling the connection between the second connecting part 42 and the connector provided on the lower surface of the battery pack 3 is to prevent the connector between the second connecting part 42 and the battery pack 3 from becoming loose when the electric surfboard is moving.
[0054] In summary, it can be seen that the electric surfboard designed with this utility model can greatly reduce the installation difficulty of the jet pump 2 and battery pack 3 on the board body 1. It eliminates the need for wiring on the board body 1, which can greatly improve the power supply and electronic control stability for users when surfing. Moreover, during subsequent maintenance, it is only necessary to remove the jet pump 2 and the conversion connector 4 from the board body 1 to complete the maintenance and replacement. It is easy to maintain and improves the user experience, and has good prospects for promotion and application value.
