Description

Technical Field

[0001] This application relates to the field of water sports equipment technology, and more specifically, to an electric surfboard. Background Technology

[0002] Existing electric surfboards are controlled by a remote control that communicates wirelessly with a controller (such as a main control board containing an MCU or other control unit). For waterproofing, the main controller and its communication module, along with other electronic components, must be housed in a waterproof enclosure, which shields the radio frequency signals. Additionally, the power battery providing electricity also shields the radio frequency signals. When the surfboard is on the water, it is frequently submerged, and the absorption of electromagnetic waves, including radio frequency signals, by seawater attenuates the signal to a very weak level, potentially causing the remote control and main controller to disconnect.

[0003] To address the aforementioned issues, existing technologies have proposed installing communication relays and modules in areas of the board that are not easily submerged in water. However, since these communication relays and modules require power, these solutions increase the complexity of the circuit design, raise manufacturing costs, and reduce waterproofing performance. Summary of the Invention

[0004] The main objective of this application is to provide an electric surfboard that addresses the problems of related technologies, such as the need for power supply, complex circuit design, high manufacturing cost, and reduced waterproofing, caused by arranging communication relays and modules on the board.

[0005] To achieve the above objectives, this application provides an electric surfboard, which includes: a board body, a battery module, a drive module, a control module, and a communication module; wherein,

[0006] The drive module is detachably connected to the board body; the control module is disposed within the drive module or within the board body, and the control module is electrically connected to the drive module and the battery module.

[0007] The communication module is housed and sealed within the plate, and includes a first antenna assembly, an RF feed line, and a second antenna assembly. The first antenna assembly is located on the portion of the plate extending out of and / or near the water surface, and is used for wireless communication with the control terminal.

[0008] The second antenna assembly is located close to the control module and is wirelessly connected to the communication terminal in the control module;

[0009] The first antenna assembly and the second antenna assembly are connected via the radio frequency feed line.

[0010] Furthermore, the first antenna assembly is located at the front end of the plate.

[0011] Furthermore, the first antenna assembly is located at the front end of the plate and around the perimeter of the plate.

[0012] Furthermore, the second antenna component is located near the communication terminal in the control module.

[0013] Furthermore, the communication terminal of the control module transmits signals outward in a spherical manner, and the second antenna assembly is located in the direction of strong transmitted signals.

[0014] Furthermore, the first antenna assembly is attached close to the surface of the plate.

[0015] Furthermore, a battery compartment is provided on the board, and the battery module is detachably disposed in the battery compartment.

[0016] Furthermore, a drive mounting slot is provided at the lower end of the board, and the drive module is detachably disposed in the drive mounting slot.

[0017] Furthermore, the drive module includes a mast, a thruster, and a hydrofoil. The hydrofoil and the thruster are fixed to the mast. The upper end of the mast is provided with a connecting part, which is detachably connected to the drive mounting slot.

[0018] Furthermore, the control module is located within the connection portion, and the second antenna assembly is arranged close to the drive mounting slot.

[0019] In this application, a board body, a battery module, a drive module, a control module, and a communication module are configured. The drive module is detachably connected to the board body. The control module is located within the drive module or within the board body, and is electrically connected to the drive module and the battery module. The communication module is located within the board body and is sealed. It includes a first antenna assembly, an RF feed line, and a second antenna assembly. The first antenna assembly is located on the portion of the board body extending above and / or near the water surface, and is used for wireless communication with a control terminal. The second antenna assembly is located near the control module and is wirelessly connected to the communication terminal within the control module. The first antenna assembly and the second antenna assembly are connected via the RF feed line, enabling the signal emitted by the control module to be stably transmitted wirelessly to the nearby second antenna assembly, and then transmitted back to the first antenna assembly via the RF feed line. Because the first antenna assembly is located on the board body extending above or near the water surface, it can stably transmit the signal wirelessly to the remote controller. Similarly, the signal emitted by the remote controller is first received by the first antenna assembly, and then transmitted via the RF feed line to the second antenna assembly. Because the second antenna assembly is relatively close to the control module, it can also stably transmit the signal to the control module.

[0020] On the one hand, the electric surfboard in this application, by arranging a first antenna assembly, a second antenna assembly, and an RF feeder at specific locations within the board, can stably transmit signals without additional power supply lines, thanks to its structural characteristics. This is particularly beneficial when applied to environments where the drive module is detachable and the control module is located within it. It eliminates the need for additional communication interfaces and lines between the second antenna assembly and the control module, enabling stable wireless signal transmission. This achieves the technical benefits of eliminating the need for active components and power supply, resulting in a simple and practical overall structure, low operating costs, and no need for additional waterproofing structures. Furthermore, it solves the problems of related technologies that require power supply, have complex wiring designs, high manufacturing costs, and reduced waterproofing due to the placement of communication relays and modules on the board. On the other hand, it effectively addresses the shielding effects of metal components within the board on signals and reduces the shielding of RF signals by seawater, thereby significantly improving the stability of signal transmission.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To address the issue of disconnection between the remote control and the control module within the circuit board due to seawater shielding, related technologies incorporate communication relays and modules in areas of the circuit board that are not easily submerged. However, these communication relays and modules require additional power supply circuits and interfaces, increasing circuit design complexity, manufacturing costs, and reducing waterproofing performance. This is especially problematic in environments where the battery and drive modules can be detached from the circuit board. Additional communication and power interfaces matching the relays and modules are needed, and these interfaces must also be waterproofed, further complicating the circuitry and waterproofing design and increasing manufacturing costs.

[0032] To solve the above technical problems, such as Figure 1 As shown in the figure, this application embodiment provides an electric surfboard, which includes: a board body 1, a battery module 2, a drive module 3, a control module 4, and a communication module; wherein,

[0033] The drive module 3 is detachably connected to the board 1; the control module 4 is located inside the drive module 3 or inside the board 1, and the control module 4 is electrically connected to the drive module 3 and the battery module 2.

[0034] The communication module is located inside the board 1 and is sealed. It includes a first antenna assembly 6, an RF feed line 5 and a second antenna assembly 7. The first antenna assembly 6 is located on the part of the board 1 that extends out of the water surface and / or is close to the water surface. The first antenna assembly 6 is used for wireless communication connection with the control terminal.

[0035] The second antenna assembly 7 is located near the control module 4 and is wirelessly connected to the communication terminal 41 in the control module 4.

[0036] The first antenna assembly 6 and the second antenna assembly 7 are connected via radio frequency feed line 5.

[0037] In this embodiment, the drive module 3 is detachably connected to the plate 1. Specifically, a position for installing the drive module 3 can be formed on the plate 1. The user can install the drive module 3 to this specific position during use. In one embodiment, a battery compartment is provided on the upper part of the plate 1. The battery compartment can be located at the lower or upper end of the plate 1; since the lower end is more likely to come into contact with water, it is preferably located at the upper end of the plate 1. The battery module 2, as an independent module, can be installed into the battery compartment via a quick-release structure, and can be waterproofed using a specific sealing structure. In one embodiment, this sealing structure includes a sealing cover that can be fastened and fixed to the battery compartment. A sealing strip can be arranged between the sealing cover and the inner wall of the battery compartment to achieve a seal. It is understood that the battery module 2 can also be enclosed within the plate, thereby facilitating the arrangement of the waterproof structure.

[0038] In one embodiment of the electric surfboard, the drive module 3 includes a mast and a thruster mounted at the lower end of the mast. The upper end of the mast can be detachably connected to the lower end of the tail of the board body 1. The thruster can be an underwater thruster consisting of a motor-shaft-propeller or a ring-shaped thruster. The electronic components in the thruster are powered by a battery module 2 installed inside the board body 1. Therefore, when the mast is fixedly connected to the board body 1, the electrical connection between the thruster and the battery module 2 is completed simultaneously.

[0039] The control module 4, serving as the signal receiving, transmission, and processing component, processes signals through its built-in control elements and receives and transmits signals through its built-in communication elements. The thrusters in the drive module 3 can be controlled by the control module 4. The control terminal (e.g., a remote control) can wirelessly transmit control signals to the control module 4, and the thrusters can also feed back signals to the control module 4. The control module 4 can then wirelessly transmit signals to the control terminal. The control module 4 can be integrated into the drive module 3 or installed separately within the board 1. When installed within the drive module 3, the communication elements in the control module 4 need to be positioned close to the board 1 to facilitate proximity to the second antenna assembly 7 installed within the board 1.

[0040] When the control module 4 is integrated into the drive module 3, since the drive module 3 is detachably connected to the board 1 in this embodiment, a stable signal transmission between the control terminal and the control module 4 can be achieved more simply and efficiently in this environment. In this embodiment, a communication module is also arranged within the board 1. The communication module includes a first antenna assembly 6, a second antenna assembly 7, and an RF feed line 5. The first antenna assembly 6 is arranged in a portion of the board 1 that extends above or near the water surface during normal use, preferably extending above the water surface and close to the surface of the board 1, thereby further reducing the impact of seawater on signal transmission. For a surfboard, its front end is usually above the water surface, so the first antenna assembly 6 is preferably arranged at the front end of the board 1. The second antenna assembly 7 is arranged close to the control module 4, and the second antenna assembly 7 is wirelessly coupled to the communication terminal 41 of the control module 4. When the control module 4 is integrated into the drive module 3, after the drive module 3 is installed, the control module 4 and the second antenna assembly 7 are close to each other, allowing the communication terminal 41 of the control module 4 to establish a stable wireless communication connection with the second antenna assembly 7.

[0041] After determining the positions of the first antenna assembly 6 and the second antenna assembly 7, signal transmission between them is achieved through the radio frequency (RF) feeder 5. Specifically, the two ends of the RF feeder 5 can be connected to the first antenna assembly 6 and the second antenna assembly 7 respectively, and the RF feeder 5 is arranged inside the board 1. Through the arrangement of the communication module in this embodiment, the RF signal emitted by the communication terminal 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 1 via the RF feeder 5, where it is then emitted. Since the first antenna assembly 6 is roughly located above the water surface, the RF signal emitted by the first antenna assembly 6 can be transmitted to the control terminal without interference from seawater, enabling the control terminal to receive the corresponding control signals remotely and wirelessly.

[0042] Meanwhile, the radio frequency signal received by the first antenna assembly 6 located at the front end of the board 1 can also be transmitted to the second antenna assembly 7 through the radio frequency feed line 5. The second antenna assembly 7 sends out the signal and receives it at the communication terminal 41 of the control module 4, thereby enabling bidirectional communication between the control module 4 and the control terminal, which can effectively improve the radio frequency communication signal of the electric surfboard.

[0043] Furthermore, since the board 1 and the drive module 3 are detachably mounted, and the second antenna assembly 7 is wirelessly coupled to the communication terminal 41 of the control module 4, no receiving line is required between the second antenna assembly 7 and the communication terminal 41, which is beneficial for waterproofing. Moreover, since this embodiment only connects the first antenna assembly 6 and the second antenna assembly 7 via the RF feed line 5 to transmit RF signals, no additional power supply circuit is required. Its design is simple, easy to manufacture, and provides stable signal transmission.

[0044] In summary, on the one hand, the electric surfboard of this application, by arranging the first antenna assembly 6, the second antenna assembly 7, and the radio frequency feed line 5 at specific locations within the board body 1, can stably transmit signals without additional power supply circuitry, thanks to its structural characteristics. This is particularly relevant when the drive module 3 is detachable and the control module 4 is located within the drive module 3. It eliminates the need for additional communication interfaces and lines between the second antenna assembly 7 and the control module 4, enabling stable wireless signal transmission. This achieves the technical benefits of eliminating the need for active devices and power supply, resulting in a simple and practical overall structure, low operating costs, and no need for additional waterproofing structures. Furthermore, it solves the problems of related technologies that require power supply, have complex circuit designs, high manufacturing costs, and reduced waterproofing when using communication relays and modules on the board body 1. On the other hand, it effectively addresses the shielding effect of metal components within the board body 1 on signals and reduces the shielding effect of seawater on radio frequency signals, thereby effectively improving the stability of signal transmission.

[0045] It is understood that the communication module in this embodiment can also be applied to environments where wireless remote control is achieved through other high-frequency communication signals such as WiFi.

[0046] Additionally, it should be noted that in one arrangement of the first antenna assembly 6, the RF feed line 5, and the second antenna assembly 7, they can be pre-arranged on a metal frame within the plate 1, and then the external structure of the plate 1 can be formed on the metal frame. This allows the first antenna assembly 6, the RF feed line 5, and the second antenna assembly 7 to be pre-embedded within the plate 1, providing good waterproofing. In another arrangement, grooves matching the first antenna assembly 6, the RF feed line 5, and the second antenna assembly 7 can be formed on the plate 1, and all three can be subsequently installed into the plate 1 and fixed and sealed using corresponding covers. It should be noted that the above arrangements are not limiting.

[0047] In one embodiment, to further improve the stability of signal transmission, the first antenna assembly 6 is disposed at the front end and periphery of the plate 1. For example, it can be arranged at the front end, rear end, left end, and right end of the plate 1, with one or more antennas arranged at each location, thereby enabling signal reception and transmission from multiple locations and further preventing the control terminal from losing connection with the control module 4. The specific arrangement location of the first antenna assembly 6 is not restrictive; it only needs to be arranged in a location affected by ambient water.

[0048] Since the second antenna component 7 is wirelessly coupled to the communication terminal 41 of the control module 4, the second antenna component 7 needs to be as close as possible to the communication terminal 41 in the control module 4 to ensure signal transmission stability. Furthermore, the communication terminal 41 of the control module 4 transmits signals outward in a spherical manner, and the second antenna component 7 is located in the direction of strong signal transmission and is as close as possible to the communication terminal 41.

[0049] To facilitate the installation of the drive module 3 onto the plate 1, a drive mounting slot is provided at the lower end of the plate 1 in this embodiment, and the drive module 3 is detachably disposed within the drive mounting slot. Furthermore, the drive module 3 includes a mast and a hydrofoil propeller. The hydrofoil and propeller are fixed to the lower end of the mast, and a connecting portion is provided at the upper end of the mast, which is detachably connected to the drive mounting slot.

[0050] In one embodiment, the connecting part and the drive mounting slot can be connected by a quick-connect structure, which can consist of bolts or clips; this embodiment is not limited to either. Since the thruster requires power from the battery module 2, the connecting part also has a connector capable of electrically connecting to the battery module 2. When the control module 4 is integrated into the drive module 3, the control module 4 is located within the connecting part, and the second antenna assembly 7 is arranged close to the drive mounting slot.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
