In order to solve the problem that the remote controller and the control module in the board body are easy to be disconnected due to the seawater shielding effect, communication relays, communication modules and the like are arranged at the positions of the board body which are not easy to be submerged in water in the related technology. Because the communication relay and the communication module need to be provided with additional power supply circuits and power supply interfaces, the technical schemes increase the complexity of circuit design, increase the manufacturing cost and reduce the waterproof performance. Especially when applied to the environment that battery module and drive module can be dismantled from the plate body, still need additionally arrange communication interface and the power supply interface with communication relay and the matching of communication module to still need to waterproof communication interface and power supply interface, lead to circuit and waterproof design further complicacy, manufacturing cost further increases.

To solve the above technical problems, as shown in fig. 1, an embodiment of the present application provides an electric surfboard, which includes: the device comprises a plate body 1, a battery module 2, a driving module 3, a control module 4 and a communication module; wherein,

the driving module 3 is detachably connected with the plate body 1; the control module 4 is arranged in the driving module 3 or in the board body 1, and the control module 4 is electrically connected with the driving module 3 and the battery module 2;

the communication module is arranged in the board body 1 and is hermetically arranged and comprises a first antenna assembly 6, a radio frequency feeder line 5 and a second antenna assembly 7, wherein the first antenna assembly 6 is arranged at a part of the board body 1 extending out of the water surface and/or approaching the water surface, and the first antenna assembly 6 is used for being in wireless communication connection with the control terminal;

the second antenna assembly 7 is close to the control module 4 and is in wireless communication connection with the communication end 41 in the control module 4;

the first antenna assembly 6 is connected to the second antenna assembly 7 by a radio frequency feed line 5.

In the present embodiment, the driving module 3 is detachably connected to the board body 1, and specifically, a position for mounting the driving module 3 may be formed on the board body 1. The user can mount the driving module 3 to a specific location when using. In one embodiment, the plate 1 is provided with a battery compartment, which may be located at the lower end or the upper end of the plate 1, and is preferably provided at the upper end of the plate 1 because the lower end is easier to contact with water. The battery module 2 can be mounted into the battery compartment through a quick-mounting structure as a separate module, and the battery module 2 can be waterproof-sealed through a specific sealing structure. In one embodiment, the sealing structure comprises a sealing cover plate which can be fastened and fixed on the battery compartment, and sealing can be realized between the sealing cover plate and the inner wall of the battery compartment through arranging a sealing strip. It will be appreciated that the battery module 2 may also be enclosed in a plate body, thereby facilitating the arrangement of the waterproof structure.

In one embodiment of the electric surfboard, the drive module 3 comprises a mast and a propeller mounted at the lower end of the mast, the upper end of the mast being detachably connectable with the lower end of the tail of the board body 1. The propeller can be an underwater propeller or an annular propeller consisting of a motor-shaft-propeller. The power supply of the electronics in the propeller is achieved by means of a battery module 2 built into the board 1. Therefore, the mast completes the electrical connection between the propeller and the battery module 2 synchronously when the mast is fixedly connected with the plate body 1.

The control module 4 is provided as a part of signal reception, transmission and processing, and performs signal processing by a built-in control element and signal reception and transmission by a built-in communication element. The propeller in the driving module 3 can be controlled by the control module 4 to act, the control terminal (such as a remote controller) can transmit control signals to the control module 4 in a wireless communication mode, meanwhile, the propeller can also feed back signals to the control module 4, and the control module 4 can transmit signals to the control terminal in a wireless transmission mode. The control module 4 may be integrally installed in the driving module 3 or may be separately installed in the board body 1. When selected for installation in the drive module 3, the communication element in the control module 4 needs to be in a position close to the board 1, so that access to the second antenna assembly 7 installed in the board 1 can be facilitated.

When the control module 4 is integrated into the driving module 3, since the driving module 3 is detachably connected with the board body 1 in this embodiment, stable signal transmission between the control terminal and the control module 4 is realized more simply and efficiently in this environment. In this embodiment, a communication module is further disposed in the board body 1, where the communication module includes a first antenna assembly 6, a second antenna assembly 7, and a radio frequency feeder 5. The first antenna component 6 is arranged at a part which can extend out of the water surface or a part which is close to the water surface in the normal use process of the board body 1, preferably a part which extends out of the water surface, and is close to the surface of the board body 1, so that the influence of seawater on signal transmission is further reduced. For surfboards, the front end of which is in most cases above the water surface, the first antenna component 6 is therefore preferably arranged at the front end of the board body 1. The second antenna assembly 7 is then arranged close to the control module 4, the second antenna assembly 7 being connected to the communication end 41 of the control module 4 by a wireless coupling. When the control module 4 is integrated into the driving module 3, the control module 4 and the second antenna assembly 7 are close to each other after the driving module 3 is installed, so that the communication end 41 of the control module 4 can establish a stable wireless communication connection with the second antenna assembly 7.

After the positioning of the first antenna assembly 6 and the second antenna assembly 7, the transmission of signals between the first antenna assembly 6 and the second antenna assembly 7 is then effected via the radio frequency feeder 5. Specifically, two ends of the rf feeder 5 may be connected to the first antenna assembly 6 and the second antenna assembly 7, respectively, and the rf feeder 5 is disposed in the board body 1. By arranging the communication modules in this embodiment, the radio frequency signal sent by the communication end 41 of the control module 4 can be received by the second antenna assembly 7, and transmitted to the first antenna assembly 6 at the front end of the board body 1 through the radio frequency feeder 5, and emitted by the first antenna assembly 6. Since the first antenna assembly 6 is located substantially above the water surface, the radio frequency signal emitted by the first antenna assembly 6 can be transmitted to the control terminal without interference from the seawater, so that the control terminal can receive the corresponding control signal in a remote wireless manner.

Meanwhile, the radio frequency signal received by the first antenna assembly 6 positioned at the front end of the board body 1 can be transmitted to the second antenna assembly 7 through the radio frequency feeder 5, and the radio frequency signal is sent by the second antenna assembly 7 and received by the communication end 41 of the control module 4, so that two-way communication between the control module 4 and the control terminal can be realized, and the radio frequency communication signal of the electric surfboard can be effectively improved.

In addition, because the board body 1 and the driving module 3 are detachably installed, the second antenna assembly 7 is connected with the communication end 41 of the control module 4 through wireless coupling, so that a receiving circuit and a line are not required to be arranged between the second antenna assembly 7 and the communication end 41, and the waterproof effect is facilitated. Furthermore, in the present embodiment, the radio frequency feeder 5 is only used to connect the first antenna assembly 6 and the second antenna assembly 7 to transmit radio frequency signals, so that no additional power supply circuit is required, the design is simple, the production and the manufacturing are easy, and the signal transmission is stable.

On the whole, on the one hand, after the first antenna component 6, the second antenna component 7 and the radio frequency feeder 5 are arranged at specific positions in the board body 1, the electric surfboard can stably transmit signals by utilizing the structural characteristics of the electric surfboard, and particularly, when the electric surfboard is applied to the driving module 3 and is detachable and the control module 4 is positioned in the driving module 3, the communication interface and the circuit of the second antenna component 7 and the control module 4 are not required to be additionally arranged, and the purpose of stably transmitting signals in a wireless mode is achieved, so that the electric surfboard can realize the technical effects of no need of using an active device, no need of power supply, simple and practical overall structure, low use cost and no need of arranging an additional waterproof structure, and further solve the problems of complex circuit design, high manufacturing cost and waterproof property reduction due to the fact that the communication relay and the communication module are arranged on the board body 1 in the related technology; on the other hand, the shielding influence of the metal parts in the plate body 1 on signals can be effectively solved, the shielding of seawater on radio frequency signals is reduced, and the stability of signal transmission can be effectively improved.

It is understood that the communication module in this embodiment can also be applied to a wireless remote control environment implemented by other high-frequency communication signals such as WiFi.

In addition, it should be noted that, in one arrangement manner of the first antenna assembly 6, the radio frequency feeder 5 and the second antenna assembly 7, the first antenna assembly 6, the radio frequency feeder 5 and the second antenna assembly 7 may be arranged on a metal skeleton in the board body 1 in advance, and then an external structure of the board body 1 is formed on the metal skeleton, so that the first antenna assembly 6, the radio frequency feeder 5 and the second antenna assembly 7 may be arranged in the board body 1 in a pre-buried manner, and thus have good waterproof performance. In another arrangement, a slot may be formed in the plate 1 that mates with the first antenna assembly 6, the rf feed 5 and the second antenna assembly 7, which may then be installed into the plate 1 and secured and sealed by corresponding covers. It should be noted that the above arrangement is not limiting.

In one embodiment, to further improve the stability of signal transmission, the first antenna component 6 in this embodiment is disposed at the front end of the board 1 and around the board 1. For example, it may be disposed at the front, rear, left and right ends of the board body 1, and one or more of the respective positions may be disposed so as to be able to receive and transmit signals at a plurality of positions, and it is possible to further prevent the disconnection of the control terminal from the control module 4. The specific arrangement position of the first antenna element 6 described above is not limited, and it is only necessary to arrange it at a position affected by the environmental water.

Since the second antenna assembly 7 is connected to the communication terminal 41 of the control module 4 through wireless coupling, the second antenna assembly 7 needs to be as close to the communication terminal 41 of the control module 4 as possible in order to ensure signal transmission stability. Further, the communication end 41 of the control module 4 transmits signals outwards in a spherical manner, and the second antenna assembly 7 is located in a direction in which the transmitted signals are strong and as close to the communication end 41 as possible.

In order to facilitate the installation of the driving module 3 onto the board 1, a driving installation groove is provided at the lower end of the board 1 in this embodiment, and the driving module 3 is detachably disposed in the driving installation groove. Further, the driving module 3 comprises a mast and a hydrofoil propeller, the hydrofoil and the propeller are fixedly arranged at the lower end of the mast, a connecting part is arranged at the upper end of the mast, and the connecting part is detachably connected with the driving installation groove.

In one embodiment, the connection portion and the driving installation groove may be connected through a quick-assembly structure, and the quick-assembly structure may be formed by a bolt or a buckle, which is not limited in this embodiment. Since the propeller needs to be powered by the battery module 2, a connector capable of being electrically connected to the battery module 2 is also provided at the connection portion. When the control module 4 is selectively integrated in the drive module 3, the control module 4 is arranged in the connection, and the second antenna assembly 7 is arranged close to the drive mounting slot.
