Description

Technical Field

[0001] The present application belongs to the technical field of underwater equipment communication and remote control, and specifically provides a modular underwater communication component, a surface and underwater communication system, and a remote control navigation device. Background Art

[0002] An underwater thruster for single-person use can use an electric propeller to provide driving force. By setting the control button on a handle fixedly connected to the underwater thruster, it is possible to send control signals such as acceleration and deceleration to the underwater thruster while holding the handle. In this application scenario, the handle and the underwater thruster are generally set up in an integrated manner or maintained in a fixed connection. Therefore, the control signal sending device can be directly embedded in the handle.

[0003] However, when the underwater thruster is used as a power device to drive a surface vehicle, the underwater thruster generally needs to be connected to different vehicles through a connecting structure to achieve adaptation to different models of surface vehicles. Obviously, in this application scenario, the existing control signal sending and receiving units are fixedly embedded in the communication method of the underwater thruster, which cannot meet the requirement of enabling the underwater thruster to be controlled by control signals from different sources.

[0004] Therefore, it is necessary to provide an underwater communication component that separates the sending end and receiving end of the control signal and is easy to disassemble and assemble, so as to ensure that when the underwater thruster is assembled to different surface vehicles, the receiving end set on the underwater thruster can be easily matched with the corresponding control signal sending end. Summary of the invention

[0005] The present application provides a modular underwater communication component through an embodiment, the modular communication component is arranged on an underwater propeller, and includes a first shell and a second shell, wherein the second shell is fixedly connected to the underwater propeller;

[0006] The underwater propeller and the first shell are provided with a sliding guide structure and a locking structure that cooperate with each other. The first shell can slide relative to the underwater propeller under the constraint of the sliding guide structure and is fixedly connected to the underwater propeller through the locking structure. A first infrared module is watertightly arranged in the first shell, and a second infrared module is watertightly arranged in the second shell. When the first shell slides to a position where it can be fixedly connected to the underwater propeller through the locking structure, the second infrared module can receive the infrared signal emitted by the first infrared module.

[0007] The modular underwater communication component provided in the embodiment of the present application separates and separately arranges the infrared signal transmitting part and the receiving part in a modular form. The receiving part is fixedly embedded in the underwater vehicle, and the transmitting part is matched with various surface navigation devices. When the underwater vehicle is assembled to the surface navigation device that needs to be driven, the first shell can be conveniently and quickly locked to the preset position on the underwater vehicle through the sliding guide structure and locking structure that cooperate with each other on the underwater vehicle and the first shell, and ensure that the infrared signal emitted by the first infrared module inside it can be reliably received by the second infrared module.

[0010] Preferably, the first limiting portion is formed by an end surface of the slide groove, and the second limiting portion is formed by an end surface of the slide rail and is arranged opposite to the first limiting portion.

[0013] Preferably, the first infrared module and the second infrared module are both infrared transceiver combined modules; a first receiving hole is also opened on the shell wall of the first shell facing the second shell side, which is used to accommodate the infrared receiving sensor of the first infrared module; a second transmitting hole is also opened on the shell wall of the second shell facing the first shell side, which is used to accommodate the infrared transmitting head of the second infrared module.

[0014] Preferably, when the first shell is fixedly connected to the outer shell of the underwater thruster through the locking structure, the first launching hole is aligned with the second receiving hole, and the second launching hole is aligned with the first receiving hole.

[0015] The present application also provides an above-water and underwater communication system through an embodiment, including a remote controller, a wireless communication module, a first adapter module, a first wired communication module, a third housing, a second wired communication module, a second adapter module, and the aforementioned modular underwater communication assembly;

[0034] Figure 1 Schematic diagram of a modular underwater communication component provided according to some embodiments of the present application, wherein the component is arranged on an underwater propeller 2 and is used to send a control signal to the underwater propeller. Figure 2 A disassembled schematic diagram of assembling the modular underwater communication assembly to an underwater propeller is further shown.

[0035] like Figure 1 , Figure 2 As shown, the modular underwater communication assembly includes a first shell 11 and a second shell 12 , wherein the second shell 12 is embedded in the outer shell of the underwater propeller 2 so as to maintain a fixed connection with the underwater propeller 2 .

[0036] Figure 3 Schematic diagram of the structure of the first shell in some optional implementations is shown, such as Figures 1 to 3 As shown, mutually cooperating sliding guide structures are provided on the underwater propeller 2 and the first shell 11. Specifically, a slide groove 111 extending along the axial direction of the underwater propeller 2 is formed at one end of the first shell 11 facing the underwater propeller 2. Correspondingly, a slide rail 21 cooperating with the slide groove 111 is provided on the outer shell of the underwater propeller 2. The slide groove 111 and the slide rail 21 form a sliding guide structure. When it is necessary to assemble the first shell 11 to the underwater propeller 2, the slide groove 111 is aligned with the slide rail 21, and then the first shell 11 is pushed. At this time, the first shell 11 slides relative to the underwater propeller 2 along the first direction under the constraint of the sliding guide structure.

[0037] Obviously, except Figures 1 to 3 The sliding guide structure shown, in some optional embodiments, can also be provided with a slide rail on the first shell 11 and a corresponding slide groove on the outer shell of the underwater thruster 2, which can also achieve restricted sliding of the first shell 11 relative to the underwater thruster 2.

[0038] Figure 4 The internal structure of the first housing 11 is shown. Figure 5 The three-dimensional structure of the second housing 12 is shown. Figure 4 As shown, a first infrared module is disposed in the first shell 11 . The first infrared module can be arranged on the circuit substrate 114 , and the water tightness of the first shell 11 can be ensured by potting glue.

[0039] A second infrared module is also watertightly arranged in the second shell 12. By sending and receiving infrared signals between the first infrared module and the second infrared module, the control signal can be transmitted from the first infrared module to the second infrared module. Accordingly, a signal transmission interface is provided on the side of the second shell 12 embedded in the underwater thruster to transmit the control signal received by the second infrared module to the control unit inside the underwater thruster 2.

[0040] In order to ensure the reliability of infrared communication between the first infrared module and the second infrared module, a locking structure that cooperates with each other is also provided on the underwater propeller 2 and the first housing 11. In some embodiments, for example, Figure 1 , Figure 2 As shown, the locking structure includes a positioning screw hole 212 arranged on the slide rail 21 of the underwater propeller 2, and a through hole 113 arranged on the first shell 11. The specific setting positions of the positioning screw hole 212 and the through hole 113 can be determined according to the intensity of the infrared signal emitted by the first infrared module received by the second infrared module, that is, it is necessary to ensure that when the first shell 11 slides to the point where the axis of its through hole 113 coincides with the axis of the positioning screw hole 212, the second infrared module can receive the infrared signal emitted by the first infrared module. At this time, the first bolt 41 can be passed through the through hole 113 and tightened in the positioning screw hole 212, so as to fix the first shell 11 to the underwater propeller 2.

[0041] It should be noted that, in the embodiment of the present application, the second infrared module can receive the infrared signal emitted by the first infrared module, which means that when the first infrared module and the second infrared module are in an underwater communication environment, the second infrared module can clearly and accurately obtain the effective information contained in the infrared signal emitted by the first infrared module, such as the control instructions in binary coded form composed of a sequence of high and low levels.

[0042] In some preferred embodiments, the positions of the through hole 113 and the positioning screw hole 212 can be further optimized according to the change in the intensity of the infrared signal received by the second infrared module during the sliding process of the first shell 11, so that when the axes of the two coincide, the intensity of the infrared signal received by the second infrared module is maximized.

[0043] Furthermore, in order to facilitate locking the first housing 11, in some preferred embodiments, as Figure 2 , Figure 3 As shown, the sliding guide structure further includes a first limiting portion 112 and a second limiting portion 211 .

[0044] Specifically, the first limiting portion 112 is formed by the end surface of the slide groove 111, and the second limiting portion 211 is formed by the end surface of the slide rail 21 and is arranged opposite to the first limiting portion 112. When the first shell 11 slides along the first direction until the through hole 113 is perpendicular to the axis of the positioning screw hole 212, the first limiting portion 112 contacts the second limiting portion 211. At this time, the first shell 11 can no longer continue to slide along the first direction, so that the first bolt 41 can be tightened conveniently.

[0045] In some preferred embodiments of the present application, the first infrared module and the second infrared module are both infrared transceiver modules, that is, they both have infrared transmitting and infrared receiving functions, thereby realizing the reception and feedback of infrared signals.

[0046] Furthermore, if Figure 3 and Figure 4 As shown, a first emitting hole 1101 is opened on the shell wall of the first shell 11 facing the second shell 12, which is used to accommodate the infrared emitting head of the first infrared module. At the same time, a second receiving hole is opened on the shell wall of the second shell 12 facing the first shell 11, which is used to accommodate the infrared receiving sensor of the second infrared module.

[0047] At the same time, a first receiving hole 1102 is opened on the shell wall of the first shell 11 facing the second shell 12, which is used to accommodate the infrared receiving sensor of the first infrared module, and a second emitting hole 1201 is opened on the shell wall of the second shell 12 facing the first shell 11, which is used to accommodate the infrared emitting head of the second infrared module.

[0048] In order to enhance the infrared communication effect, in some preferred embodiments, when the first shell 11 is fixedly connected with the underwater propeller 2 through the through hole 113 and the positioning screw hole 212, the first transmitting hole 1101 is aligned with the second receiving hole 1202, and the second transmitting hole 1201 is aligned with the first receiving hole 1102. At this time, the intensity of the infrared signal between the two infrared modules can be ensured to be maximum.

[0049] like Figure 1 , Figure 2As shown, in the embodiment of the present application, the slide rail 21 of the underwater propeller 2 is also used to cooperate with the connecting structure 22 to realize the assembly of the underwater propeller 2 with various types of surface navigation devices. Specifically, the connecting structure 22 is made of corrosion-resistant and high-strength lightweight materials, and its upper part can be fixedly connected to the lower surface of various types of surface navigation devices, and its lower part is provided with a slide groove structure similar to the slide groove 111 on the first shell 11, and the slide rail 21 can be entered from the other end of the slide rail 21 along the second direction and slide along the slide rail. The slide rail 21 is also provided with a positioning screw hole 213 matching the connecting structure 22. When the connecting structure 22 slides until the through hole provided thereon coincides with the positioning screw hole 213, the connecting structure 22 and the underwater propeller can be fixedly connected by the second bolt 42, so that the underwater propeller is assembled to the bottom of the surface navigation device.

[0050] Correspondingly, a wire connector 115 is also provided on the first shell 11. The wire connector 115 passes through the first shell 11 and is watertight. The spring wire 15 enters the first shell 11 through the wire connector 115, and is used to transmit the control instructions sent from the top of the surface navigation device to the first shell 11 in a wired communication manner.

[0051] The modular underwater communication component provided in the embodiment of the present application separates and separately arranges the infrared signal transmitting part and the receiving part in a modular form. The receiving part is fixedly embedded in the underwater vehicle, and the transmitting part is matched with various surface navigation devices (also called surface navigation vehicles). When the underwater vehicle is assembled to the surface navigation device that needs to be driven, the first shell can be conveniently and quickly locked to the preset position on the underwater vehicle through the sliding guide structure and locking structure that cooperate with each other on the underwater vehicle and the first shell, and ensure that the infrared signal emitted by the first infrared module inside it can be reliably received by the second infrared module. By using the above-mentioned modular underwater communication component, the application scenarios of the underwater propeller can be effectively expanded, and it can be effectively remotely controlled when it provides drive for different types of surface navigation devices.

[0052] The above modular underwater communication components can further constitute a complete surface and underwater communication system as a part. Figure 6 The working principle of applying the above-mentioned above-water and underwater communication system including the above-mentioned modular underwater communication components to a remote-controlled navigation device in some embodiments is shown. Figure 7 The remote-controlled navigation device was enlarged and displayed. Figure 8 A structural framework of a surface and underwater communication system provided according to some embodiments is shown.

[0053] Specifically, the above-water and underwater communication system is composed of a remote control 14 located above the water surface, a wireless communication module, a first adapter module, a first wired communication module, a second wired communication module located below the water surface, a second adapter module and the above-mentioned modular underwater communication components.

[0054] The remote controller 14 is connected to the wireless communication module via a wireless communication protocol such as the 2.4G protocol, and the first adapter module is connected to the wireless communication module and the first wired communication module circuit. Figures 6 to 8 As shown, the wireless communication module, the first adapter module and the first wired communication module can be arranged in the third shell 13. The third shell 13 can be set on the upper surface of the paddle board 3 by Velcro or other fixing methods. It is also watertight and has wire connectors. The spring wire 15 enters the third shell 13 through the wire connector and is connected to the first wired communication module.

[0055] The second adapter module is electrically connected to the second wired communication module and the first infrared module. The second wired communication module and the second adapter module can be arranged in the first shell, and the spring wire 15 introduced from the wire connector 115 is electrically connected to the second wired communication module, thereby realizing the wired communication connection between the first wired communication module and the second wired communication module.

[0056] When the underwater propeller 2 is assembled below the paddle board 3 , the first housing 11 connected to the third housing 13 through the spring line 15 can be simultaneously slid along the slide groove 21 to a locked position to achieve a fixed connection with the underwater propeller 2 .

[0057] The above-water and underwater communication system first sends a remote control command to the wireless communication module through a remote controller using a 2.4G wireless communication protocol or other methods. The first adapter module converts the received remote control command into a wired signal such as a CAN signal, and then uses the first wired communication module and the second wired communication module to introduce the remote control signal from the above-water part to the underwater part using a wired connection. The signal is then converted again in the underwater part through the second adapter module to convert the wired signal into an infrared signal, so as to perform the original infrared remote control of the underwater thruster.

[0058] Through this above-water and underwater communication system, the operator can send control instructions by wireless remote control above the paddle board 3 and other surface navigation vehicles, while ensuring that the control instructions can effectively pass through the paddle board 3 and other surface navigation vehicles into the underwater part, avoiding the problem of short signal transmission distance in infrared mode and poor infrared signal penetration when the paddle board 3 exists; finally, the original infrared mode is still used in the underwater part to send instructions to the underwater thruster, without modifying the signal receiving method and control logic of the existing underwater thruster, so that it can be compatible with the operation method of remote control from water to underwater, thereby effectively expanding the application scenarios of underwater thrusters. Obviously, in addition to Figure 6 , Figure 7 As shown in the paddle board 3, the above-water and underwater communication system can also be applied to various other types of surface navigation vehicles to form different remote-controlled navigation devices.

[0059] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
