[0045] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0046] In the related art, the power part and the mast part are provided in a split structure for easy disassembly and use, and a mounting groove is formed on the power part or the mast part to connect the other part, and a connector arranged in the mounting groove is used to achieve electrical connection. However, since the power part needs to be operated underwater for a long time, the stress is complex, and the simple use of the mounting groove to achieve the connection of the two parts will result in poor connection stability, and therefore an additional locking member (such as a screw) needs to be arranged to increase the connection stability, resulting in that the installation and disassembly are still inconvenient.

[0047] To solve the above technical problems, as shown in Figures 1 to 5 The embodiment of the present application provides a power system for a hydrofoil plate, which comprises a mast assembly 1 and a power assembly 21; wherein,

[0048] The first end of the mast assembly 1 is provided with a first connecting part 3, and the first connecting part 3 is provided with a first connecting port 18;

[0049] The power assembly 21 comprises a fuselage 4, and the two ends of the fuselage 4 are respectively provided with a front hydrofoil (not shown in the figure) and a tail wing 7. A connecting groove 5 is formed on the fuselage 4, and a second connecting port 15 is arranged in the connecting groove 5;

[0050] The connecting groove 5 is provided as a through groove, and the first connecting part 3 is arranged to be detachably inserted into the connecting groove 5 in a plug-in manner, and the first connecting port 18 and the second connecting port 15 are detachably electrically connected;

[0051] The two ends of the first connecting part 3 are tightly fitted with the two sides of the connecting groove 5.

[0052] In the embodiment, the power system cooperates with the plate body to form an electric hydrofoil plate, and the power system mainly comprises the mast assembly 1 and the power assembly 21. The mast assembly 1 is substantially a vertical rod structure, the upper end of which is connected with the plate body, and the lower end of which is connected with the power assembly 21. The main body structure of the power assembly 21 is a fuselage 4, and the two ends of the fuselage 4 are arranged with a front hydrofoil and a tail wing 7. When used as an electric hydrofoil plate, the fuselage 4 is arranged with a motor and a propeller 6, and the propeller 6 is located close to the tail wing 7. The propeller 6 is rotated by the motor to provide thrust, so that the front hydrofoil and the tail wing 7 generate lift under the action of water flow.

[0053] For easy carrying and use, the mast assembly 1 and the power assembly 21 are detachably connected in the embodiment. Specifically, as shown in Figure 2 and Figure 3As shown, the first connecting part 3 is arranged at the lower end of the mast assembly 1 by opening a connecting groove 5 on the fuselage 4, and the first connecting part 3 and the connecting groove 5 are matched by insertion. During installation, the first connecting part 3 is inserted into the connecting groove 5. In order to ensure sufficient connection stability of the mast assembly 1 and the fuselage 4 after connection and reduce the installation of additional locking members, the connecting groove 5 is arranged as a through groove in this embodiment, and the front hydrofoil and the tail wing 7 are arranged at both ends of the fuselage 4. It should be noted that the connecting groove 5 in this embodiment is a through groove, which means that the connecting groove 5 is open in the width direction and has side walls in the length direction matched with both ends of the first connecting part 3.

[0054] The front hydrofoil and the tail wing 7 arranged at both ends of the fuselage 4 are used to provide lift to make the fuselage 4 deform upward, and the deformation will act on both sides of the connecting groove 5 to make both sides of the connecting groove 5 press the both ends of the first connecting part 3 towards the middle. The connecting groove 5 is arranged as a through groove to make it easier to press the first connecting part 3 towards the middle under the action of the lift. If the connecting groove 5 is a groove closed on all sides, it is not conducive to the deformation of the connecting groove 5, and even if it deforms, the both sides of the connecting groove 5 in the length direction will press the first connecting part 3 towards the middle during the deformation, but the both sides in the width direction will separate from the first connecting part 3 due to the pressing force, and the both sides in the width direction will be difficult to recover after the deformation, resulting in a decrease in the connection strength of the first connecting part 3 and the connecting groove 5.

[0055] Therefore, the connecting groove 5 is arranged as a through groove in this embodiment, and the front hydrofoil and the tail wing 7 arranged at both ends of the fuselage 4 are used to generate lift to compress the first connecting part 3, thereby improving the connection strength of the mast assembly 1 and the fuselage 4. Due to the improvement of the connection strength, additional locking members can be considered not to be used or the number of locking members can be reduced after installation, which is convenient for installation and disassembly.

[0056] Generally, in addition to the motor, the fuselage 4 also has an electronic speed controller part for controlling the action of the motor, and the power supply part and the main control part of the motor need to be installed into the mast assembly 1 or the board. Since the board has a large area, the power supply part is preferably installed in the board to ensure the endurance, and the main control part can be installed according to the actual design.

[0057] Since the mast assembly 1 and the fuselage 4 are detachably connected, the electrical connection of the electronic devices in the mast assembly 1 and the electronic devices in the fuselage 4 needs to be realized synchronously during disassembly and connection. Therefore, as shown in FIG. 6, the fuselage 4 is provided with a plurality of connecting grooves 5, and the mast assembly 1 is provided with a plurality of first connecting parts 3 matched with the connecting grooves 5. The first connecting part 3 is arranged on the lower end of the mast assembly 1, and the first connecting part 3 and the connecting groove 5 are matched by insertion. During installation, the first connecting part 3 is inserted into the connecting groove 5. Figures 2 to 4As shown, in the first connecting part 3 of the embodiment, a first connecting port 18 is arranged, and a second connecting port 15 is arranged in the connecting groove 5. The first connecting port 18 is electrically connected with the electronic device in the mast assembly 1, and can be connected or welded by a cable. The second connecting port 15 is electrically connected with the electronic device in the fuselage 4, and can be connected or welded by a cable. The first connecting port 18 and the second connecting port 15 can be connected by a male-female terminal plug or a contact connection. Since the first connecting part 3 and the connecting groove 5 are connected by plug-in, the first connecting port 18 and the second connecting port 15 can be connected by a male-female terminal plug or a contact connection. In order to further improve the connection stability of the mast assembly 1 and the fuselage 4, and improve the connection stability of the first connecting port 18 and the second connecting port 15, the two connecting ports are preferably connected by plug-in.

[0058] In an embodiment, the first connecting port 18 and the second connecting port 15 are each provided as three ports, two of which are power positive or negative, two of which are power negative or positive, and the other is a communication port. The other is a communication port. In the above-mentioned ports, the power positive port and the power negative port can be connected by a male-female terminal plug, and the two communication ports can also be connected by a male-female terminal plug. Of course, other non-wired plug-in methods can also be used, such as wireless Bluetooth connection.

[0059] In the embodiment, when the mast assembly 1 and the fuselage 4 are connected by the first connecting part 3 and the connecting groove 5, the front hydrofoil and the tail wing 7 at both ends of the fuselage 4 provide upward lift during use. Since the connecting groove 5 is a through groove, the two sides of the connecting groove 5 will press the two ends of the first connecting part 3 upward, so that the first connecting part 3 can be stably fixed in the connecting groove 5, thereby achieving the technical effect of making the mast assembly 1 and the power assembly 21 easy to install and disassemble and ensuring sufficient connection stability, thereby solving the problem of difficulty in installing and disassembling the mast part and the power part of the hydrofoil plate in the related art.

[0060] In order to control the motor operation of the fuselage 4, the fuselage 4 in the embodiment is provided with an electric adjustment assembly, which is arranged at the bottom of the connecting groove 5 and electrically connected with the second connecting port 15. In the embodiment, the second connecting port 15 needs to be plugged with the first connecting port 18, so the second connecting port 15 needs to be arranged on the bottom surface of the connecting groove 5. Since the electric adjustment assembly needs to be electrically connected with the second connecting port 15, in order to facilitate the connection of the electric adjustment assembly and the second connecting port 15 and reduce the connection path, the electric adjustment assembly is arranged at the bottom of the connecting groove 5, so as to be relatively close to the second connecting port 15.

[0061] As shown in Figure 5 The electric adjustment assembly includes an electric adjustment plate 20, which is perpendicular to the mast assembly 1. The second connecting port 15 is fixed vertically on the electric adjustment plate 20 and electrically connected with the electric adjustment plate 20. The first connecting port 18 and the second connecting port 15 are oppositely arranged.

[0062] Specifically, it should be noted that the electric adjustment plate 20 is a PCB board for controlling the motor operation in the fuselage 4, and the electric adjustment plate 20 is arranged with positive and negative electrode and signal line pads. In order to facilitate the connection of the second connecting port 15 arranged in the plugging direction on the electric adjustment plate 20, the electric adjustment plate 20 is arranged in a perpendicular manner to the mast assembly 1, so the electric adjustment plate 20 is also perpendicular to the second connecting port 15. The second connecting port 15 can be welded on the positive and negative electrode and signal line pads. Correspondingly, the first connecting port 18 can be welded and fixed at the corresponding position of the first connecting part 3, and the first connecting port 18 can be connected to the main control board installed in the mast assembly 1 through a wire. In the embodiment, the first connecting port 18 can be a copper column male terminal or a copper column female terminal, and the second connecting port 15 can be a copper column female terminal or a copper column male terminal.

[0063] On the basis of the plugging of the first connecting part 3 and the connecting groove 5, in order to further utilize the lift of the front hydrofoil and the tail wing 7 to improve the connection stability, the first connecting part 3 in the embodiment is further provided with a connecting clamping groove (not shown in the figure), and the connecting groove 5 is provided with a connecting protrusion (not shown in the figure), which is detachably clamped in the connecting clamping groove. In the process of plugging the first connecting part 3 and the connecting groove 5, the first connecting port 18 and the second connecting port 15 are plugged, at the same time, the connecting protrusion is clamped in the connecting clamping groove, and the extrusion force of the two sides of the connecting groove 5 to the middle of the connecting groove 5 caused by the upward lift of the front hydrofoil and the tail wing 7 presses the connecting protrusion in the connecting clamping groove, thereby further improving the connection strength between the mast assembly 1 and the fuselage 4. Since the clamping mode is adopted, no additional parts are needed during installation and disassembly, and the installation and disassembly are more convenient.

[0064] On the basis of the plug-in fit of the first connecting part 3 and the connecting groove 5 and the clamping connection of the connecting groove and the connecting protrusion, in order to further strengthen the connecting strength of the mast assembly 1 and the fuselage 4, the mast assembly 1 and the fuselage 4 are connected by screws in the embodiment. In order to reduce the number of screws used and balance the stress at the connection, the screws are vertically installed in the first connecting part 3 and located in the middle of the first connecting part 3. Since the electric adjustment plate 20 is located at the bottom of the connecting groove 5, the screws need to avoid occupying the installation space of the electric adjustment plate 20 when being vertically inserted.

[0065] To this end, as shown in Figure 3 and Figure 4 , the embodiment is provided with a mounting part 14 on both sides of the connecting groove 5, the mounting part 14 is located above the electric adjustment plate 20, and the first connecting part 3 is fixedly connected with the mounting part 14 by screws. The mounting part 14 located above the electric adjustment plate 20 can provide a mounting position for the screws, so that when the screws are vertically screwed into the mounting part 14, the lower end of the screws still maintains sufficient connecting strength without extending to the depth of the electric adjustment plate 20. In an embodiment, the mounting part 14 close to the front hydrofoil can be a part of the fuselage 4, and the mounting part 14 close to the tail wing 7 can be an installation table additionally installed in the connecting groove 5, and the installation table and the side wall of the connecting groove 5 can be connected by screws.

[0066] The reason why the mounting table is additionally arranged only at one end close to the tail wing 7 to form the mounting part 14 on this side in the embodiment is that the propeller 6 is arranged at one end of the fuselage 4 close to the tail wing 7, and the electric machine driving the propeller 6 is also installed at one end close to the tail wing 7, so the electric adjustment plate 20 electrically connected with the electric machine will also be relatively close to the tail wing 7. Therefore, there is a lack of mounting space for the screws on the side of the connecting groove 5 close to the tail wing 7, so as to avoid the electric adjustment plate 20 while providing sufficient connecting strength, the embodiment additionally installs a mounting table on this side to install the screws. At the same time, since there is a certain cavity between the first connecting part 3 and the connecting groove 5 at this position, the mounting table is arranged in the cavity to install the screws, which can improve the space utilization.

[0067] In order to facilitate the installation of the first connecting port 18 and the second connecting port 15, as shown in Figures 2 to 5 , the embodiment is provided with a first plastic part 8 in the first connecting part 3, a second plastic part 12 in the connecting groove 5, the second connecting port 15 is arranged in the second plastic part 12, and the first connecting port 18 is arranged in the first plastic part 8;

[0068] The first plastic part 8 is provided with a first plug-in part 81, and the second plastic part 12 is provided with a second plug-in part 121. The abutting part of the second connecting port 15 is located in the second plug-in part 121, and the abutting part of the first connecting port 18 is located in the first plug-in part 81. The second plug-in part 121 and the first plug-in part 81 are plug-in matched, and the abutting part of the second connecting port 15 and the abutting part of the first connecting port 18 are plug-in matched.

[0069] A sealing ring 19 is arranged between the second plug-in part 121 and the first plug-in part 81.

[0070] Specifically, it should be noted that the first connecting part 3 has a mounting position for fixedly mounting the first plastic part 8, and the connecting groove 5 also has a mounting position for mounting the second plastic part 12. The connection between the first plastic part 8 and the first connecting part 3 needs to be sealed, and the connection between the second plastic part 12 and the connecting groove 5 also needs to be sealed. The first plastic part 8 is provided with the first connecting port 18. Since the first connecting port 18 needs to be connected to other electronic devices in the mast assembly 1 through a wire, the first connecting part 3 is provided with a hole corresponding to the first connecting port 18. Similarly, the first plastic part 8 also needs to have a hole corresponding to the first connecting port 18. The number of holes is determined according to the number of plugs in the first connecting port 18.

[0071] In order to improve the connection sealing performance of the first connecting port 18 and the second connecting port 15 after plug-in, the lower end of the first plastic part 8 is provided with the first plug-in part 81, and the abutting part of the first connecting port 18 for abutting with the second connecting port 15 is located in the first plug-in part 81. Similarly, the upper end of the first plastic part 8 is provided with the second plug-in part 121, and the abutting part of the second connecting port 15 for abutting with the first connecting port 18 is located in the second plug-in part 121. When the mast assembly 1 is connected to the fuselage 4, the first plug-in part 81 is plugged into the second plug-in part 121, and the abutting part of the first connecting port 18 is plugged into the abutting part of the second connecting port 15. At this time, the abutting parts of the two connecting ports are surrounded by the first plug-in part 81 and the second plug-in part 121, and the first plug-in part 81 and the second plug-in part 121 are in an inner-outer sleeve connection mode. Therefore, after sealing between the two plug-in parts, the abutting parts of the two connecting ports can be sealed. Therefore, in this embodiment, a sealing ring 19 is arranged between the second plug-in part 121 and the first plug-in part 81, as shown in Figure 5

[0072] In one embodiment, as Figure 3 ​As shown, the first plug-in part 81 is sleeved outside the second plug-in part 121. In order to facilitate the installation of the sealing ring 19, a plurality of sealing grooves 1211 are arranged outside the second plug-in part 121 in the embodiment. The sealing grooves 1211 are arranged in sequence along the axial direction of the second plug-in part 121, and the sealing ring 19 can be sleeved on each sealing groove 1211. When the first plug-in part 81 is plugged into the second plug-in part 121, the sealing ring 19 is pressed on the inner side of the first plug-in part 81, thereby sealing the connection between the first plug-in part 81 and the second plug-in part 121. Meanwhile, the plurality of sealing rings 19 distributed along the axial direction can form multi-stage sealing to improve the sealing performance, and the arrangement of the sealing ring 19 can increase the friction between the first plug-in part 81 and the second plug-in part 121 after connection, thereby improving the connection stability.

[0073] In order to further improve the waterproof sealing effect, in the embodiment, the end faces of the second plastic part 12 and the first plastic part 8 abut, and a sealing gasket 17 is embedded at the abutting position. The sealing gasket 17 is arranged around the second plug-in part 121. Specifically, it should be noted that in the embodiment, the sealing gasket 17 can be pre-embedded on the upper end face of the second plastic part 12. After the mast assembly 1 and the fuselage 4 are connected, the first plastic part 8 will press the sealing gasket 17, thereby sealing the connection end face of the first plastic part 8 and the second plastic part 12 by using the deformation of the sealing gasket 17.

[0074] In order to facilitate the installation of the second plastic part 12 into the connecting groove 5, an installation plate 11 is arranged in the connecting groove 5 in the embodiment. The installation plate 11 is provided with a second installation hole 22, and the second plastic part 12 is fixedly arranged in the second installation hole.

[0075] Specifically, it should be noted that the bottom of the connecting groove 5 also has an installation chamber in the embodiment. Electronic devices such as the electronic adjustment plate 20 are arranged in the installation chamber, and the installation chamber is in communication with the connecting groove 5. In order to achieve waterproof treatment, an installation plate 11 is arranged to isolate the installation chamber and the upper space of the connecting groove 5, and sealing treatment is performed between the installation plate 11 and the inner wall of the installation chamber. Specifically, a sealing ring can be arranged to achieve the sealing treatment. The installation plate 11 used for isolation also serves as the installation base of the second plastic part 12. The second connection port 15 in the second plastic part 12 needs to pass through the installation plate 11 and be connected to the electronic adjustment plate 20 located in the installation chamber.

[0076] Therefore, the second installation hole 22 is formed on the installation plate 11 in the embodiment. The lower part of the second plastic part 12 passes through the second installation hole 22, and the upper part extends out of the second installation hole 22. In order to seal the connection between the second plastic part 12 and the second installation hole 22, a glue injection groove 16 is formed on one end of the second installation hole 22 towards the first plastic part 8 in the embodiment. The glue injection groove 16 is filled with sealing glue to seal the connection between the second installation hole and the second plastic part 12.

[0077] In the embodiment, the glue injection groove 16 is arranged around the second plug-in part 121, which is located at the outer ring of the sealing gasket 17. The present application has sufficient waterproof sealing between the first connecting port 18 and the second connecting port 15 by the arrangement of the sealing ring 19 and the sealing gasket 17, and has sufficient waterproof sealing between the second plastic part 12 and the mounting hole by the arrangement of the glue injection groove 16.

[0078] In order to facilitate the butt joint of the first connecting port 18 and the second connecting port 15, as shown in the figure, a certain position floating amount is required for the first connecting port 18 in the process of connection. For this purpose, a first mounting hole is arranged on the first connecting part 3 in the embodiment, a connecting hole corresponding to the first mounting hole is arranged on the first plastic part 8, and a limiting pin 9 is arranged in the connecting hole. Figure 3

[0079] The diameter of the limiting pin 9 is smaller than the inner diameter of the connecting hole, both ends of the limiting pin 9 pass through the connecting hole and are sleeved with a soft pad 10, the soft pad 10 abuts against both sides of the first plastic part 8, and the end of the limiting pin 9 away from the second plastic part 12 is fixedly connected with the first connecting part 3.

[0080] Specifically, it needs to be explained that the connecting hole can be arranged as four and located at the four corners of the first plastic part 8, and the corresponding first mounting hole is also arranged as four. Since the diameter of the limiting pin 9 is smaller than the diameter of the connecting hole, when the limiting pin 9 is fixedly connected with the first mounting hole, the first plastic part 8 can move forward, backward, left and right in the horizontal direction relative to the limiting pin 9, and the diameter difference between the limiting pin 9 and the connecting hole is equivalent to the maximum moving amount of the first plastic part 8 in the central position towards each direction. On this basis, in order to avoid the first plastic part 8 from shaking at will, a soft pad 10 is sleeved on the limiting pin 9 in the embodiment, and the soft pad 10 abuts against the surface of the first plastic part 8. By arranging the soft pad 10, the friction of the movement of the first plastic part 8 is increased, so that the first plastic part 8 can keep a certain range of floating while being relatively stable.

[0081] ​In the embodiment, the first connection port 18 and the second connection port 15 constitute the connector of the mast assembly 1 and the fuselage 4, and there is a contact impedance between the two. If the connection device is unreliable, the contact impedance is too large during operation, which can easily cause the temperature of the part to be too high, which can affect the charging power output, or even cause the connector to lose control of heat, causing a safety accident. If the connection port is worn during long-term plugging, the connection port may not be fully plugged, which can cause the impedance at the connection to be too large, and thus the temperature of the connection port to be too high. To solve the problem of overheating of the connector, a temperature protection device is usually used, which includes a temperature detection and control circuit. In the selection of the connector and the temperature detection scheme, the difficulty is how to balance the cost of the connector and the safety problem of the temperature detection circuit and the high-voltage circuit. The existing solution is to fix the plug-in temperature sensor on the connector shell by heat-conducting glue. The connector shell is usually made of plastic. This method has two problems. First, the selection of the connector is limited, and the cost is relatively high. Second, the production process is complex, and the temperature sensor and the connector need to be glued and fixed

[0082] Therefore, the power assembly 21 in the embodiment further includes a temperature sensor (not shown in the figure), which is arranged close to the second connection port 15 and used to detect the temperature at the connection between the second connection port 15 and the first connection port 18.

[0083] Specifically, it should be noted that the temperature sensor can be welded to the position close to the second connection port 15 on the electronic speed controller board 20 to detect the temperature at the connection between the second connection port 15 and the first connection port 18. Alternatively, the temperature sensor and the electronic speed controller board 20 can be connected by wires, so that the position of the temperature sensor is more flexible, and the temperature sensor can be kept at a safe distance from the connection port while being as close to the heat source as possible, so that the specific temperature of the connection port can be obtained more accurately.

[0084] In another embodiment, since the contact impedance will increase when the connection is unreliable, the voltage and / or current of the connection port can also be detected to determine whether the voltage and / or current is within a preset normal threshold or a preset normal threshold range, so as to determine whether the connection port has a connection abnormality problem.

[0085] Specifically, in the embodiment, the power assembly 21 further includes a current / voltage detection module (not shown in the figure), which is used to detect the current and voltage of the second connection port 15 and the first connection port 18.

[0086] In another embodiment, the connection of the connection port can also be judged by a sensor for position detection to determine whether the connection has a connection abnormality. Specifically, the power assembly 21 further comprises a position detection sensor (not shown in the figure) arranged on the fuselage 4 and / or the mast assembly 1, for detecting the relative position of the second connection port 15 and the first connection port 18.

[0087] For example, the connection of the connection port can be judged by a Hall sensor. When the Hall sensor detects a change in the magnetic field, it can be determined that the current connection of the connection port is abnormal, when the magnetic field reaches a preset threshold or the range of the magnetic field change exceeds a preset range value. For another example, the connection of the connection port can be judged by infrared. An infrared receiving (or sending) end is arranged in the first connection port 18 (or the second connection port 15), and a corresponding infrared sending (or receiving) end is arranged in the second connection port 15 (or the first connection port 18). If the infrared receiving end cannot receive the infrared light sent by the corresponding infrared sending end, it can be determined that the current two connection ports have a connection abnormality.

[0088] When it is determined that the connection of the connection port has an abnormality by the above method, a prompt information can be sent to prompt the user. For example, an abnormality prompt can be made on a remote controller in communication connection with the hydrofoil board to control the hydrofoil board.

[0089] Further, the power system further comprises a main control system 2 and a power supply system (not shown in the figure), the main control system 2 and the power supply system are electrically connected, and the main control system 2 is electrically connected with the electronic speed controller assembly through the second connection port 15 and the first connection port 18. In one embodiment, the main control system 2 is arranged at the upper end of the mast assembly 1, and the power supply system is arranged in the board body of the hydrofoil board. As shown in the figure, the main control system 2 is detachably connected with the second connection part 22 on the mast assembly 1, and is detachably electrically connected with the power supply system, and is electrically connected with the electronic speed controller assembly (the electronic speed controller board 20) in the fuselage 4 after the first connection port 18 and the second connection port 15 are docked. Figure 1

[0090] The detachable electrical connection of the first connection part 3 and the power supply system can be realized by an electrical connector, and the connection and disconnection can be realized by plugging. It can be understood that the connection of the first connection part 3 and the power supply system can also use the connection and cooperation of the first connection port 18 and the second connection port 15 in the above embodiment, and this embodiment will not be described again.

[0091] ​In the prior art, the user needs to turn off the power supply before disassembling the mast assembly 1 and the power assembly 21 through the plugging and unplugging of the connection port, so as to disassemble the power assembly 21 and avoid the danger of sparking caused by hot plugging (plugging under power). However, in many cases, the user directly performs hot plugging, and turning off the power supply before disassembling the power assembly 21 needs to turn the hydrofoil over back and forth, which is cumbersome for the user and has a poor experience.

[0092] Therefore, the present application can further automatically turn off the power supply at the moment when the user performs hot plugging by detecting the board or the connection port, so as to avoid sparking during the plugging and unplugging process of the user, that is, to realize "hot plugging" from the user experience.

[0093] In an embodiment, the power system for the hydrofoil further comprises a posture detection sensor (not shown in the figure), such as a gyroscope, which is used to detect the posture of the board. When the posture of the board is in a set posture, the posture detection sensor sends an electrical signal to the main control system 2, and the main control system 2 controls the power supply system to be powered off after receiving the electrical signal.

[0094] Since the user needs to turn the board over during the plugging and unplugging process in most cases, the posture detection sensor can send an instruction to the main control system 2 when it detects that the board has been turned over to a preset posture, and the main control system 2 turns off the power supply system based on the instruction.

[0095] In another embodiment, the power assembly 21 further comprises a position detection sensor (not shown in the figure), which is arranged on the fuselage 4 and / or the mast assembly 1 and is used to detect the relative position of the second connection port 15 and the first connection port 18.

[0096] When the relative position of the second connection port 15 and the first connection port 18 is in a set position, the position detection sensor sends an electrical signal to the main control system 2, and the main control system 2 controls the power supply system to be powered off after receiving the electrical signal.

[0097] Specifically, a sensor for position detection can be arranged at the connection port to determine whether the connection of the connection port is in a disengaged state, and when it is determined that the connection of the connection port is in a disengaged state, an instruction can be sent to the main control system 2 to make the main control system 2 control the power system to be turned off, so as to avoid sparking during user plugging, i.e. to achieve "hot plugging" from the user experience. For example, when the Hall sensor detects a change in the magnetic field, i.e. the magnetic field reaches a preset threshold or the magnetic field change range exceeds a preset range value, it can be determined that the connection of the current connection port is in a disengaged state, and an instruction can be sent to the main control system 2, and the main control system 2 responds to the instruction to turn off the power. Similarly, the connection state of the main control system 2 can also be determined by infrared.

[0098] Preferably, the scheme of detecting the posture and detecting whether the connection of the connection port is in a disengaged state can be combined. If it is detected that the board body is flipped to a preset posture, and it is determined that the connection of the connection port is in a disengaged state, an instruction can be sent to the main control system 2 to make the main control system 2 control the hydrofoil board to turn off the power, so as to improve the accuracy of the determination and avoid power off caused by false triggering.

[0099] According to another aspect of the present application, an electric hydrofoil board is provided, comprising a board body and the above-mentioned power system, and the second end of the mast assembly 1 is detachably connected to the board body through the second connection portion 22.

[0100] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
