Description

Technical Field

[0001] This utility model relates to the field of surfboard technology, and in particular to an electric surfboard. Background Technology

[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 consist of a board body, a jet pump, and a battery pack. In practice, the battery pack is usually detachably mounted on the upper surface of the board body for easy replacement by the user. However, existing electric surfboards often place the jet pump inside the board body (mid-mounted jet pump) or mounted from the bottom up on the lower surface of the board body (bottom-mounted jet pump). While this ensures the stability of the jet pump installation, it is not conducive to disassembling and replacing the jet pump. At the same time, jet pumps mounted on the lower surface of the board are easily damaged by direct contact and friction with the ground due to dragging on land, which will affect subsequent maintenance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an electric surfboard that solves the problems of existing electric surfboards having a centrally located or bottom-mounted spray pump, which makes it difficult to disassemble and replace the pump and easily damages the pump due to dragging the board on land.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an electric surfboard, comprising: a board body, a jet pump, and a contour-following fixing member, wherein a receiving groove is recessed on the upper surface of one end of the board body, the contour-following fixing member is disposed in the receiving groove and is detachably connected to the board body to form a receiving cavity with the receiving groove, wherein the cross-sectional area of ​​the receiving cavity at the end near the tail of the board body in the length direction is smaller than the cross-sectional area at the other end away from the tail of the board; wherein the jet pump is detachably installed in the receiving cavity.

[0006] Furthermore, in the electric surfboard described in this utility model, the accommodating groove is wider at the top and narrower at the bottom in the vertical height direction.

[0007] Furthermore, in the electric surfboard described in this utility model, a battery compartment is recessed and formed on the upper surface of the board body, and the battery compartment is used to load a battery pack.

[0008] Furthermore, in the electric surfboard described in this utility model, the battery compartment and the receiving groove are arranged sequentially along the length direction of the board body.

[0009] Furthermore, in the electric surfboard described in this utility model, a through cavity is provided on the side of the battery compartment near the receiving groove, and the two ends of the through cavity are respectively connected to the receiving groove and the battery compartment.

[0010] Furthermore, the electric surfboard of this utility model also includes an electrical connector, which is disposed in the through cavity, with one end of the electrical connector extending into the receiving groove and electrically connected to the jet pump; the other end of the electrical connector extends into the battery compartment and is electrically connected to the battery pack.

[0011] Furthermore, in the electric surfboard described in this utility model, the spray pump has a drainage channel including an inlet and an outlet, and the bottom of the receiving groove has a through hole; wherein, the inlet is positioned directly opposite the through hole.

[0012] Furthermore, in the electric surfboard described in this utility model, the spray pump is provided with a drive mechanism, the drive mechanism includes a motor and a propeller assembly, the propeller assembly is disposed in the drainage channel, and the motor is connected to the propeller assembly in a transmission connection, the motor being used to drive the propeller assembly to rotate.

[0013] Furthermore, the electric surfboard described in this utility model also includes a wing, which is detachably disposed on the lower surface of the board body.

[0014] The beneficial effects of this utility model are as follows: This utility model designs a brand-new electric surfboard. The installation method of the jet pump in this electric surfboard has been adjusted. By forming a receiving groove on the upper surface of the board, the jet pump can be detachably installed in the receiving groove from top to bottom along the vertical height direction. Specifically, this electric surfboard adopts a top-mounted jet pump, that is, the lower surface of the board is the same as that of a conventional surfboard, and the jet pump does not protrude from the lower surface of the board. Instead, it is supported and accommodated by the receiving groove of the board. At this time, the user can directly remove the jet pump from the upper surface of the board without flipping the board. Even if the jet pump malfunctions while playing on the water, the user can directly remove the top-mounted jet pump from the upper surface of the board and install a new jet pump, thereby greatly reducing the difficulty of disassembly and assembly.

[0015] Therefore, the electric surfboard designed with this utility model can greatly reduce the difficulty of disassembling and assembling the jet pump. Its lower surface is the same as that of a conventional surfboard, so the jet pump will not directly contact and rub against the ground when the user drags the board on land.

[0018] 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.

[0019] like Figures 1-8As shown, in this embodiment, the present invention designs an electric surfboard, which includes: board body 1, battery pack 3, jet pump 2 and contour fixing member 8. The jet pump 2 and battery pack 3 are detachably mounted on board body 1, and the jet pump 2 and battery pack 3 are electrically connected through electrical connector 4.

[0020] like Figure 1 , Figure 3 As shown, in this utility model, the spray pump 2 is specifically selected as an upper-mounted spray pump to facilitate subsequent disassembly and assembly of the spray pump 2. That is, a receiving groove 11 is recessed and formed on the upper surface of one end of the electric surfboard body 1. The conforming fixing member 8 is disposed in the receiving groove 11 and is detachably connected to the board body 1 to form a receiving cavity with the receiving groove 11. The cross-sectional area of ​​the receiving cavity at the end near the tail of the board in the length direction of the board body is smaller than the cross-sectional area at the other end away from the tail of the board. The spray pump 2 is detachably installed in the receiving cavity. At the same time, in this embodiment, the control spray pump 2 is specifically detachably installed in the receiving groove 11 from top to bottom in the vertical height direction.

[0021] Therefore, it can be seen that in the electric surfboard designed in this utility model, the installation method of the jet pump 2 has been adjusted. The electric surfboard adopts an upper-mounted jet pump, that is, the lower surface of the board body 1 is the same as that of a conventional surfboard, and the jet pump 2 does not protrude from the lower surface of the board body 1. Instead, it is supported and accommodated by the receiving groove 11 of the board body 1. At this time, the user can directly remove the jet pump 2 from the upper surface of the board body 1 without flipping the board body 1. Even if the jet pump 2 malfunctions while playing on the water, the user can directly remove the jet pump 2 from the upper surface of the board body 1 and install a new jet pump 2, thereby greatly reducing the difficulty of disassembling and assembling the jet pump 2.

[0022] Accordingly, see further Figure 1 and Figure 3 In this embodiment, in order to facilitate the user to install the battery pack 3, the upper surface of the plate 1 is also partially recessed and a battery compartment 12 is formed, so that the battery pack 3 can be detachably disposed in the battery compartment 12.

[0023] 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 slot in an upper-mounted manner. This installation method allows users to install and disassemble them very easily, thereby greatly reducing the difficulty of maintenance and replacement.

[0024] In this embodiment, in order to further simplify the user's installation process, in actual application, the width of the slot 11 in the vertical height direction can be controlled to be wider at the top and narrower at the bottom, so that it is easier for the user to place the spray pump 2 in the slot 11.

[0025] Accordingly, such as Figure 1 , Figure 2 As shown, in this embodiment, when the above-mentioned spray pump 2 is installed in the 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.

[0026] To ensure that pump 2 can function properly, such as Figure 3 As shown, in this embodiment, a through hole 13 is specifically opened at the bottom of the above-mentioned receiving groove 11, and the spray pump 2 is provided with a drainage channel including a water inlet 21 and a water outlet 22, so that the water inlet 21 of the drainage channel can be set directly opposite the through hole 13; at this time, the water outlet 22 of the 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 and the plate 1, so that the water flow entering the drainage channel from the through hole 13 and the water inlet 21 is sprayed out from the water outlet 22, thereby generating a counter-thrust force to move the plate 1.

[0027] A filter screen 24 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.

[0028] like Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, in order to effectively drive the plate 1 to move, the spray pump includes a pump body and a motor 6 and a propeller assembly 9 disposed in the pump body. The propeller assembly 9 can correspond to the above-mentioned drainage channel, and the motor 6 can be driven to drive the propeller assembly 9 to rotate, thereby driving the water flow of the drainage channel to be sprayed out from the outlet 22 of the spray pump 2.

[0029] At the same time, such as Figure 3 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 user can send control commands by pressing the control button 7, thereby controlling and adjusting the kinetic energy output of the motor 6.

[0030] Accordingly, when water is ejected from the outlet 22 of the 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 receiving groove 11 of the board body 1 due to the counter-thrust, in this embodiment, as follows: Figure 3As 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 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 receiving groove 11 and lock the position of the spray pump 2 in the receiving groove 11 to prevent the spray pump 2 from loosening and shifting during operation.

[0031] In addition, in this invention, a plurality of blades 5 are provided on the lower surface of the board body 1 of the electric surfboard. These blades 5 can be arranged symmetrically on the left and right sides along the central axis of the board body 1, and the blades 5 can improve the forward stability of the electric surfboard in water.

[0032] In addition, in this utility model, an electrical connector 4 is specifically provided to establish an electrical connection between the spray pump 2 and the battery pack 3. The electrical connector 4 is easy to install and has strong connection reliability.

[0033] See Figure 5 As shown, in this embodiment, in order to facilitate the installation of the electrical connector 4, a through cavity 14 is provided on the side of the battery compartment 12 of the electric surfboard body 1 near the receiving groove 11. The through cavity 14 is connected to the receiving groove 11 and the battery compartment 12 respectively, so that the electrical connector 4 can be disposed in the through cavity 14. One end of the electrical 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 electrical connector 4 extends into the second receiving cavity and is electrically connected to the battery pack 3.

[0034] Because the aforementioned electrical connector 4 is located in the through cavity 14 between the receiving groove 11 and the battery compartment 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 electrical 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 battery compartment 12.

[0035] See also Figure 5 As shown, in this embodiment, the electrical connector 4 can specifically adopt an L-shaped structure design. The electrical connector 4 can specifically include a first connecting part 41 and a second connecting part 42. The first connecting part 41 and the second connecting part 42 are connected and form an L-shape. 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.

[0036] In summary, it can be seen that the electric surfboard designed using this utility model can greatly reduce the difficulty of disassembling and assembling the jet pump. The lower surface of the board is the same as that of a conventional surfboard, and the jet pump will not directly contact and rub against the ground due to the user dragging the board on land. It has good prospects for promotion and application value.
