Description

Power system for hydrofoil board and electric hydrofoil board Technical Field

[0001] The present application relates to the technical field of hydrofoil boards, and in particular to a power system for hydrofoil boards. Background Art

[0002] For currently powered hydrofoil panels, the power supply and signal lines of the power section are connected to the main control board of the mast section through welding wires or adapters, making installation and disassembly of the mast section difficult. In order to facilitate disassembly and use, the power section and the mast section are set as a split structure in the related art, which uses a mounting groove on the power section or the mast section to connect to the other section, and a connector is arranged in the mounting groove to achieve electrical connection. However, since the power section needs to operate underwater for a long time and is subjected to complex forces, simply using the mounting groove to achieve connection between the two will result in poor connection stability. Therefore, additional locking parts (such as screws) are required to increase the connection stability, resulting in inconvenience in installation and disassembly.

[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] To facilitate disassembly and use, related technologies have separated the power unit and mast unit into separate structures. Mounting slots are provided on either the power unit or the mast to connect to the other unit, with connectors placed within the mounting slots to achieve electrical connection. However, since the power unit needs to operate underwater for extended periods and is subject to complex forces, simply using mounting slots to connect the two units results in poor connection stability. Therefore, additional locking elements (such as screws) are required to increase connection stability, making installation and disassembly still relatively inconvenient.

[0048] To solve the above technical problems, as shown in Figures 1 to 5, an embodiment of the present application provides a power system for a hydrofoil board, the power system for a hydrofoil board comprising: a mast assembly 1 and a power assembly 21; wherein,

[0049] The first end of the mast assembly 1 is provided with a first connecting portion 3 , and the first connecting portion 3 is provided with a first connecting port 18 ;

[0050] The power assembly 21 includes a fuselage 4, with a front hydrofoil (not shown) and a tail wing 7 provided at both ends of the fuselage 4. A connecting slot 5 is provided on the fuselage 4, and a second connecting port 15 is provided in the connecting slot 5.

[0051] The connection slot 5 is configured as a through slot, and the first connection portion 3 is configured to be detachably inserted into the connection slot 5 in a plug-in manner, so as to detachably electrically connect the first connection port 18 and the second connection port 15;

[0052] Both ends of the first connecting portion 3 are tightly fitted with both sides of the connecting groove 5 .

[0053] In this embodiment, the power system, combined with the board, forms an electric hydrofoil board. The power system primarily comprises a mast assembly 1 and a power assembly 21. The mast assembly 1 is a roughly vertical pole structure, with its upper end connected to the board and its lower end connected to the power assembly 21. The main structure of the power assembly 21 is a fuselage 4, with a front hydrofoil and a tail fin 7 positioned at either end. When used as an electric hydrofoil board, the fuselage 4 is equipped with a motor and propeller 6, located proximate to the tail fin 7. The motor drives the propeller 6 to rotate, providing thrust, which in turn generates lift under the action of the water flow on the front hydrofoil and tail fin 7.

[0054] To facilitate portability, the mast assembly 1 and the power assembly 21 are detachably connected in this embodiment. Specifically, as shown in Figures 2 and 3, a connection slot 5 is provided on the fuselage 4, and a first connection portion 3 is provided at the lower end of the mast assembly 1. The first connection portion 3 and the connection slot 5 are engaged with each other by plugging. During installation, the first connection portion 3 is inserted into the connection slot 5. In order to ensure sufficient connection stability between the mast assembly 1 and the fuselage 4 after connection while reducing the installation of additional locking parts, the connection slot 5 is provided as a through slot in this embodiment, and a front hydrofoil and a tail wing 7 are respectively arranged at both ends of the fuselage 4. It should be noted that the connection slot 5 in this embodiment is a through slot, which means that the connection slot 5 is an open structure in the width direction and has side walls in the length direction that cooperate with the two ends of the first connection portion 3.

[0055] The purpose of arranging the front hydrofoils and tail fins 7 at each end of the fuselage 4 is to utilize the lift provided by the front hydrofoils and tail fins 7 to cause the fuselage 4 to deform upward. This deformation acts on both sides of the connecting groove 5, causing them to squeeze the ends of the first connecting portion 3 toward the center. Designating the connecting groove 5 as a through-groove facilitates the compression of the first connecting portion 3 toward the center under the action of lift. Some connecting grooves 5 that are enclosed on all sides are less likely to deform. Even if deformation occurs, the longitudinal sides of the connecting groove 5 will compress the first connecting portion 3 toward the center, while the width sides will separate from the first connecting portion 3 due to the compressive force. Furthermore, the width sides will be difficult to recover after deformation, resulting in a decrease in the connection strength between the first connecting portion 3 and the connecting groove 5.

[0056] Therefore, in this embodiment, the connection groove 5 is configured as a through groove, and the front hydrofoils and tail fins 7 arranged at both ends of the fuselage 4 generate lift to compress the first connection portion 3, thereby improving the connection strength between the mast assembly 1 and the fuselage 4. Due to the improved connection strength, after installation, it is possible to eliminate the need for additional locking members or reduce the number of locking members used, thereby facilitating installation and removal.

[0057] Generally, in addition to the motor, the fuselage 4 will also be equipped with an electric adjustment part for controlling the motor's movement, and the power supply part and the main control part of the motor need to be installed in the mast assembly 1 or the board body. Since the board body has a large area, in order to ensure endurance, the power supply part is preferably installed in the board body, and the main control part can be installed at a position selected according to the actual design.

[0058] Because the mast assembly 1 and the fuselage 4 are detachably connected, simultaneous electrical connection between the electronic components within the mast assembly 1 and the electronic components within the fuselage 4 is required during both removal and connection. To this end, as shown in Figures 2-4 , in this embodiment, a first connection port 18 is provided within the first connection portion 3, and a corresponding second connection port 15 is provided within the connection slot 5. The first connection port 18 is electrically connected to the electronic components within the mast assembly 1, specifically by cable connection or soldering, while the second connection port 15 is electrically connected to the electronic components within the fuselage 4, specifically by cable connection or soldering. The first connection port 18 and the second connection port 15 can be connected using male and female plug-in terminals or contact points. Since the first connection portion 3 and the connection slot 5 are plug-in, the first connection port 18 and the second connection port 15 can be electrically connected simultaneously using either male and female plug-in terminals or contact points. To further enhance the stability of the connection between the mast assembly 1 and the fuselage 4, as well as the stability of the connection between the first connection port 18 and the second connection port 15, a plug-in connection is preferred.

[0059] In one embodiment, there are three first connection ports 18 and three second connection ports 15, two of which are respectively the positive or negative power supply ports, two of which are respectively the negative or positive power supply ports, another first connection port 18 is a communication port, and the corresponding second connection port 15 is also a communication port. Among the above-mentioned ports, the positive power supply port and the negative power supply port can be connected by male and female plug-in connection, and the two communication ports can also be connected by male and female plug-in connection. Of course, other non-wired plug-in connection methods can also be used for connection, such as wireless Bluetooth connection, etc.

[0060] In this embodiment, when the mast assembly 1 and the fuselage 4 are connected through 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 squeeze 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 installation and disassembly of the mast assembly 1 and the power assembly 21 more convenient and ensuring sufficient connection stability, thereby solving the problem that the mast part and the power part of the hydrofoil plate in the related art are more difficult to install and disassemble.

[0061] To facilitate control of the motor operation of body 4, an electronically adjustable component is installed within body 4 in this embodiment. This component is located at the bottom of connection slot 5, and second connection port 15 is electrically connected to the component. In this embodiment, second connection port 15 is pluggable with first connection port 18, so second connection port 15 is located on the bottom surface of connection slot 5. Because the electronically adjustable component needs to be electrically connected to second connection port 15, and to facilitate the connection between the electronically adjustable component and second connection port 15 and minimize the connection path, in this embodiment, the electronically adjustable component is located at the bottom of connection slot 5, relatively close to second connection port 15.

[0062] As shown in Figure 5, the electric adjustment component includes an electric adjustment board 20, which is perpendicular to the mast assembly 1. The second connection port 15 is vertically fixed on the electric adjustment board 20 and electrically connected to the electric adjustment board 20; the first connection port 18 and the second connection port 15 are arranged opposite to each other.

[0063] Specifically, it should be noted that the electric adjustment board 20 is a PCB board used to control the operation of the motor in the fuselage 4. The electric adjustment board 20 is provided with positive and negative electrodes and signal line pads. To facilitate the connection of the second connection port 15 arranged along the plug-in direction to the electric adjustment board 20, the electric adjustment board 20 is arranged perpendicular to the mast assembly 1. Therefore, the electric adjustment board 20 and the second connection port 15 are also maintained perpendicular. The second connection port 15 can be welded to the positive and negative electrodes and signal line pads. Correspondingly, the first connection port 18 can be welded and fixed to the corresponding position of the first connection portion 3. The first connection port 18 can be connected to the main control board installed in the mast assembly 1 via a wire. In this embodiment, the first connection port 18 can be a copper pillar male terminal or a copper pillar female terminal, and the second connection port 15 can be a copper pillar female terminal or a copper pillar male terminal.

[0064] On the basis of the plug-in connection between the first connecting portion 3 and the connecting slot 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 portion 3 in this embodiment is also provided with a connecting slot (not shown in the figure), and a connecting protrusion (not shown in the figure) is provided in the connecting slot 5. The connecting protrusion is removably engaged with the connecting slot. During the plug-in connection between the first connecting portion 3 and the connecting slot 5, the first connecting port 18 and the second connecting port 15 are plugged in, and the connecting protrusion is simultaneously engaged with the connecting slot. The upward lift of the front hydrofoil and the tail wing 7 causes the two sides of the connecting slot 5 to press toward the center of the connecting slot 5, pressing the connecting protrusion into the connecting slot, thereby further improving the connection strength between the mast assembly 1 and the fuselage 4. Because of the use of a snap-in method, no additional parts are required during installation and removal, making installation and removal more convenient.

[0065] Building on the plug-in fit between the first connecting portion 3 and the connecting slot 5, and the snap-fit ​​connection between the connecting slot and the connecting protrusion, in this embodiment, to further strengthen the connection between the mast assembly 1 and the fuselage 4, the mast assembly 1 and fuselage 4 are connected using screws. To reduce the number of screws used and ensure balanced force at the connection, the screws are vertically inserted into the first connecting portion 3 and located in the middle of the first connecting portion 3. Because the electric adjustment board 20 is located at the bottom of the connecting slot 5, the screws must be inserted vertically to avoid occupying the installation space of the electric adjustment board 20.

[0066] To this end, as shown in Figures 3 and 4, in this embodiment, mounting portions 14 are provided on both sides of the connection slot 5. The mounting portions 14 are located above the electric adjustment plate 20, and the first connection portion 3 is fixedly connected to the mounting portions 14 by screws. The mounting portion 14 located above the electric adjustment plate 20 can provide a mounting position for the screw, so that when the screw is vertically screwed into the mounting portion 14, the lower end of the screw still maintains sufficient connection strength without extending to the depth of the electric adjustment plate 20. In one embodiment, the mounting portion 14 near the front hydrofoil can be part of the fuselage 4, and the mounting portion 14 near the tail wing 7 can be an additional mounting platform installed in the connection slot 5. The mounting platform can be connected to the side wall of the connection slot 5 by screws.

[0067] The reason for arranging an additional mounting platform only at one end near the tail 7 in this embodiment to form the mounting portion 14 on that side is that a propeller 6 is arranged at the end of the fuselage 4 near the tail 7, and the corresponding motor driving the propeller 6 is also installed at the end near the tail 7. Therefore, the electric adjustment board 20 electrically connected to the motor is also relatively close to the tail 7. For this reason, there is a lack of space for screw installation on the side of the connecting groove 5 near the tail 7. Therefore, in order to avoid the electric adjustment board 20 while providing sufficient connection strength, this embodiment provides an additional mounting platform on this side for installing screws. At the same time, since there is a certain cavity between the first connecting portion 3 and the connecting groove 5 at this position, arranging the mounting platform in this cavity for installing screws can improve space utilization.

[0068] To facilitate installation of the first connection port 18 and the second connection port 15, as shown in Figures 2 to 5, in this embodiment, a first plastic member 8 is provided in the first connection portion 3, a second plastic member 12 is provided in the connection groove 5, the second connection port 15 is provided in the second plastic member 12, and the first connection port 18 is provided in the first plastic member 8;

[0069] The first plastic part 8 is provided with a first plug-in portion 81, and the second plastic part 12 is provided with a second plug-in portion 121. The docking portion of the second connection port 15 is located on the second plug-in portion 121, and the docking portion of the first connection port 18 is located on the first plug-in portion 81. The second plug-in portion 121 and the first plug-in portion 81 are pluggably mated, and the docking portion of the second connection port 15 and the docking portion of the first connection port 18 are pluggably mated.

[0070] A sealing ring 19 is provided between the second plug-in portion 121 and the first plug-in portion 81 .

[0071] Specifically, it should be noted that the first connecting portion 3 has an installation position for fixedly installing the first plastic part 8, and the connecting groove 5 also has an installation position for installing the second plastic part 12. The connection between the first plastic part 8 and the first connecting portion 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 connection port 18 is installed in the first plastic part 8. Since the first connection port 18 needs to be connected to other electronic devices in the mast assembly 1 through wires, the first connecting portion 3 has a hole corresponding to the first connection port 18. Similarly, the first plastic part 8 also needs a hole corresponding to the first connection port 18. The number of holes here is determined by the number of plugs in the first connection port 18.

[0072] To enhance the sealability of the connection between the first connection port 18 and the second connection port 15 after insertion, the lower end of the first plastic component 8 in this embodiment has a first plug-in portion 81. The docking portion of the first connection port 18 for docking with the second connection port 15 is located within the first plug-in portion 81. Similarly, the upper end of the first plastic component 8 has a second plug-in portion 121. The docking portion of the second connection port 15 for docking with the first connection port 18 is located within the second plug-in portion 121. When the mast assembly 1 and the fuselage 4 are connected, the first plug-in portion 81 plugs into the second plug-in portion 121, and the docking portion of the first connection port 18 plugs into the docking portion of the second connection port 15. At this point, the docking portions of the two connection ports are surrounded by the first plug-in portion 81 and the second plug-in portion 121. The first plug-in portion 81 and the second plug-in portion 121 are arranged in an inner-outer connection. Therefore, the docking portions of the two connection ports can be sealed after the seal between the two plug-in portions is sealed. To this end, in this embodiment, a sealing ring 19 is provided between the second plug-in portion 121 and the first plug-in portion 81 , as shown in FIG. 5 .

[0073] In one embodiment, as shown in FIG3 , the first plug-in portion 81 is sleeved on the outside of the second plug-in portion 121. To facilitate the installation of the sealing ring 19, a plurality of sealing grooves 1211 are arranged on the outside of the second plug-in portion 121 in this embodiment. The plurality of sealing grooves 1211 are arranged in sequence along the axial direction of the second plug-in portion 121, and a sealing ring 19 can be sleeved on each sealing groove 1211. When the first plug-in portion 81 is plugged into the second plug-in portion 121, the sealing ring 19 is squeezed against the inner side of the first plug-in portion 81, thereby sealing the connection between the first plug-in portion 81 and the second plug-in portion 121. At the same time, the plurality of sealing rings 19 distributed along the axial direction can form a multi-stage seal to improve the sealing performance, and the arrangement of the sealing rings 19 can increase the friction force after the first plug-in portion 81 and the second plug-in portion 121 are connected, thereby improving the connection stability.

[0074] To further enhance the waterproof sealing effect, in this embodiment, the end surfaces of the second plastic component 12 and the first plastic component 8 abut against each other, and a sealing gasket 17 is embedded in the abutment point. The sealing gasket 17 is arranged around the second plug-in portion 121. Specifically, it should be noted that in this embodiment, the sealing gasket 17 can be pre-embedded in the upper end surface of the second plastic component 12. After the mast assembly 1 and the fuselage 4 are connected, the first plastic component 8 will squeeze the sealing gasket 17, thereby utilizing the deformation of the sealing gasket 17 to seal the connecting end surface of the first plastic component 8 and the second plastic component 12.

[0075] To facilitate installation of the second plastic component 12 in the connecting groove 5 , a mounting plate 11 is provided in the connecting groove 5 in this embodiment. The mounting plate 11 is provided with a second mounting hole 22 , and the second plastic component 12 is fixed in the second mounting hole.

[0076] Specifically, it should be noted that in this embodiment, the bottom of the connection groove 5 also has an installation chamber, which houses electronic components such as the electric adjustment board 20. The installation chamber is connected to the connection groove 5. To achieve waterproofing, a mounting plate 11 is required to isolate the installation chamber from the upper space of the connection groove 5. A sealing process is also required between the mounting plate 11 and the inner wall of the installation chamber, which can be achieved by arranging a sealing ring. The insulating mounting plate 11 also serves as the mounting base for the second plastic part 12. The second connection port 15 in the second plastic part 12 needs to pass through the mounting plate 11 and connect to the electric adjustment board 20 located in the installation chamber.

[0077] To this end, in this embodiment, a second mounting hole 22 is defined in the mounting plate 11. The lower portion of the second plastic component 12 extends through the second mounting hole 22, while the upper portion extends upwardly out of the second mounting hole 22. To seal the connection between the second plastic component 12 and the second mounting hole 22, a glue injection groove 16 is defined in the second mounting hole 22 at one end facing the first plastic component 8. Sealant is injected into the glue injection groove 16 to seal the connection between the second mounting hole and the second plastic component 12.

[0078] In this embodiment, the glue injection groove 16 is arranged around the second plug-in portion 121 and is located on the outer ring of the sealing gasket 17. The arrangement of the sealing ring 19 and the sealing gasket 17 ensures sufficient waterproof sealing between the first connection port 18 and the second connection port 15. The arrangement of the glue injection groove 16 also ensures sufficient waterproof sealing between the second plastic part 12 and the mounting hole.

[0079] To facilitate the connection between the first connection port 18 and the second connection port 15, as shown in FIG3 , a certain amount of positional floating is required for the first connection port 18 during the connection process. To this end, in this embodiment, a first mounting hole is provided on the first connection portion 3, and a connecting hole corresponding to the first mounting hole is provided on the first plastic member 8, with a limit pin 9 disposed in the connecting hole.

[0080] The diameter of the limit bolt 9 is smaller than the inner diameter of the connecting hole. Both ends of the limit bolt 9 pass through the connecting hole and are covered with soft pads 10. The soft pads 10 are against both sides of the first plastic part 8; the end of the limit bolt 9 away from the second plastic part 12 is fixedly connected to the first connecting part 3.

[0081] Specifically, it should be noted that four connection holes can be provided and located at the four corners of the first plastic part 8, and correspondingly, four first mounting holes are also provided. Since the diameter of the stop bolt 9 is smaller than the diameter of the connection hole, when the stop bolt 9 is fixedly connected to the first mounting hole, the first plastic part 8 can move horizontally relative to the stop bolt 9, front and back, left and right, and the diameter difference between the stop bolt 9 and the connection hole is equivalent to the maximum movement of the first plastic part 8 in all directions at the center position. On this basis, to prevent the first plastic part 8 from shaking randomly, in this embodiment, a soft pad 10 is provided on the stop bolt 9, and the soft pad 10 is against the surface of the first plastic part 8. The provision of the soft pad 10 increases the friction of the movement of the first plastic part 8, allowing the first plastic part 8 to maintain a certain range of floating while remaining relatively stable.

[0082] In this embodiment, the first connection port 18 and the second connection port 15 form a connector between the mast assembly 1 and the fuselage 4. There will be contact impedance between the two. If the connection device is unreliable, the contact impedance will be too large during operation, which will easily cause the part to overheat. At the very least, it will affect the charging power output, and at worst, the connector will thermally run away and cause a safety accident. If the connection port is damaged during long-term plugging, it will cause incomplete plugging of the connection port, which will cause the impedance at the connection to be too large, and then the temperature of the connection port will be too high. To address the problem of connector overheating, the usual solution is to add a temperature protection device, which includes a temperature detection and control circuit. In the scheme of connector selection and temperature detection, the difficulty is how to balance the cost of the connector with the safety issues of the temperature detection circuit and the high-voltage circuit. The existing solution is to fix the plug-in temperature sensor to the connector housing with thermal conductive glue. The connector housing is usually made of plastic. There are two problems with this method. First, the selection of connectors is limited. It must be made of insulating shell material, which is relatively expensive. Second, the production process is complicated, and it is necessary to add a step of gluing and fixing the temperature sensor to the connector.

[0083] To this end, the power assembly 21 in this embodiment further includes a temperature sensor (not shown in the figure), which is arranged close to the second connection port 15 and is used to detect the temperature at the connection point after the second connection port 15 and the first connection port 18 are connected.

[0084] Specifically, it should be noted that the temperature sensor can be soldered to the electrically adjustable board 20 near the second connection port 15 to detect the temperature at the junction of the second connection port 15 and the first connection port 18. Alternatively, the temperature sensor and the electrically adjustable board 20 can be connected via a wire, thereby allowing for greater flexibility in the placement of the temperature sensor. This allows the temperature sensor to maintain a safe distance from the connection port while being as close to the heat source as possible, thereby enabling more accurate measurement of the specific temperature of the connection port.

[0085] In another embodiment, since the contact impedance will increase when the connection is unreliable, it is also possible to detect the voltage and / or current of the connection port to determine whether the voltage and / or current are within a preset normal threshold or within a preset normal threshold range, thereby determining whether there is a connection abnormality problem at the connection port.

[0086] Specifically, in this 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 .

[0087] In another embodiment, a position detection sensor can be used to determine whether there is a connection abnormality in the connection port. Specifically, the power assembly 21 also includes a position detection sensor (not shown in the figure). The position detection sensor is provided 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.

[0088] For example, the connection of the connection port can be determined by a Hall sensor. When the Hall sensor detects a change in the magnetic field, which can be when the magnetic field reaches a preset threshold or when the magnetic field change range exceeds a preset range, it can be determined that the connection of the current connection port is abnormal. For another example, the connection of the connection port can be determined by infrared. An infrared receiving (or transmitting) end is provided in the first connection port 18 (or the second connection port 15), and a corresponding infrared transmitting (or receiving) end is provided 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 transmitting end, it can be determined that there is an abnormal connection between the two connection ports.

[0089] When it is determined by the above method that there is an abnormality in the connection of the connection port, a prompt message can be issued to prompt the user. For example, an abnormality prompt can be issued on a remote control that is connected to the hydrofoil board for controlling the hydrofoil board.

[0090] Furthermore, the power system also includes a main control system 2 and a power supply system (not shown). The main control system 2 and the power supply system are electrically connected, and the main control system 2 is electrically connected to the electric adjustment assembly via the second connection port 15 and the first connection port 18. In one embodiment, the main control system 2 is disposed at the upper end of the mast assembly 1, and the power supply system is disposed within the hydrofoil panel. As shown in Figure 1, the main control system 2 is removably connected to the panel via the second connection portion 22 on the mast assembly 1. It is also removably electrically connected to the power supply system. After the first connection port 18 and the second connection port 15 are docked, the main control system 2 is electrically connected to the electric adjustment assembly (electric adjustment panel 20) within the fuselage 4.

[0091] The detachable electrical connection between the first connection portion 3 and the power system can be achieved using an electrical connector, which can be connected and removed by plugging. It is understood that the connection between the first connection portion 3 and the power 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 repeated.

[0092] In the prior art, when removing the mast assembly 1 and power assembly 21 by plugging or unplugging the connection ports, the user must first turn off the power supply to facilitate removal of the power assembly 21, thereby avoiding the risk of sparks caused by hot plugging (plugging or unplugging while the power is on). However, in many cases, hot plugging is unavoidable, and turning off the power supply before removing the power assembly 21 requires flipping the hydrofoil back and forth, which is cumbersome for the user and provides a poor user experience.

[0093] Therefore, the present application can further detect the board or connection port to automatically turn off the power supply at the moment the user performs hot plugging, thereby avoiding sparks during the user's plugging and unplugging process, that is, realizing "hot plugging" from the user experience.

[0094] In one embodiment, the power system for the hydrofoil board also includes a posture detection sensor (not shown in the figure), such as a gyroscope. The posture detection sensor is used to detect the posture of the board body. When the posture of the board body is in a set posture, the posture detection sensor sends an electrical signal to the main control system 2. After receiving the electrical signal, the main control system 2 controls the power supply system to cut off power.

[0095] Since users need to flip the board during plugging and unplugging in most cases, the posture detection sensor can send an instruction to the main control system 2 when it detects that the board has flipped to a preset posture, and the main control system 2 shuts down the power system based on the instruction.

[0096] In another embodiment, the power assembly 21 further includes a position detection sensor (not shown in the figure), which is provided 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;

[0097] When the relative positions of the second connection port 15 and the first connection port 18 are at the 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 cut off power after receiving the electrical signal.

[0098] Specifically, a sensor for position detection can be provided at the connection port to determine whether the connection of the connection port is in a disconnected state, and when it is determined that the connection of the connection port is in a disconnected state, an instruction can be sent to the main control system 2 to make the main control system 2 control the power supply system to shut down, thereby avoiding the situation of sparks generated during the user's plugging and unplugging process, that is, achieving "hot plugging" from the user experience. For example, when the Hall sensor detects a change in the magnetic field, which can be that 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 disconnected state, thereby sending an instruction to the main control system 2, and the main control system 2 shuts down the power supply in response to the instruction. Similarly, the connection status of the main control system 2 can also be determined by infrared.

[0099] Preferably, a solution for detecting the posture and detecting whether the connection port is disconnected can be combined. If it is detected that the board body has flipped to a preset posture and it is determined that the connection port is disconnected, a command can be sent to the main control system 2 to control the hydrofoil board to turn off the power, thereby improving the accuracy of the determination and avoiding power off due to false triggering.

[0100] According to another aspect of the present application, an electric hydrofoil board is provided, comprising a board body and the above-mentioned power system, wherein the second end of the mast assembly 1 is detachably connected to the board body via a second connecting portion 22 .

[0101] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
