[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figure 1-11 Specific embodiments of the present invention will be described in detail below.

[0019] In this invention, the terms "connection" and "linked" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral structure.

[0020] In this invention, the terms "inner", "outer", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] This invention provides an unmanned surface vessel, see appendix. Figures 1-4The unmanned surface vessel (USV) includes a float 10 and an electrical control box 20 fixed to the float 10. The float 10 includes a battery compartment 110, a power compartment 160, and a partition 100 separating the two. The partition 100 has a first electrical docking part 101, for example, the first electrical docking part 101 can be a first waterproof connector, which is sealed to the partition 100. The battery compartment 110 has independent second electrical docking parts 111 and third electrical docking parts 112, for example, the second electrical docking part 111 can be a second waterproof connector, and the third electrical docking part 112 can be a third waterproof connector, which are sealed to the battery compartment 110 respectively. The battery 150 in the battery compartment 110 is electrically connected to the power control box 20 through the second electrical docking part 111. The control box 20, i.e., the two ends of the second electrical docking part 111 are electrically connected to the battery 150 in the battery compartment 110 and the control box 20, respectively, for transmitting the electrical energy of the battery 150 to the control box 20; the control box 20 is electrically connected to the propulsion assembly 170 of the power compartment 160 via the third electrical docking part 112 and the first electrical docking part 101 in sequence. That is, the two ends of the first electrical docking part 101 are electrically connected to the power compartment 110 and one end of the third electrical docking part 112, respectively, and the other end of the third electrical docking part 112 is electrically connected to the control box 20. The control box 20 is used to receive the electrical energy of the battery 150 via the third electrical docking part 112 and modulate it, and then transmit it to the propulsion assembly 170 via the first electrical docking part 111 to drive the propulsion assembly 170 to operate. It should be noted that the electrical control box 20 integrates electronic devices such as power management, motor drive, and communication. The electrical control box 20 is used to receive electrical energy from the battery 150, distribute and modulate it, and then deliver it to the propulsion component 170 and other electrical electronic devices, as well as to execute control commands for the unmanned vessel. The partition 100 is used to physically separate the battery compartment 110 and the power compartment 160, achieving independent sealing of the battery compartment 110 and the power compartment 160, and preventing liquid in the power compartment 160 from entering the battery compartment 110.

[0022] The present invention provides an unmanned surface vessel (USV) that, by providing a first electrical docking part 101 in the bulkhead 100 and two independent second electrical docking parts 111 and third electrical docking parts 112 in the battery compartment 110, achieves partitioned isolation between the power supply circuit of the battery 150 and the power circuit of the propulsion assembly 170, avoiding strong and weak electrical coupling interference in the prior art, thereby improving the operational reliability of the USV; on the other hand, it achieves segmented electrical connection, allowing fault diagnosis to be carried out segmentally, avoiding the full spread of faults, thereby enhancing the stability and safety of the USV's power supply.

[0023] In this embodiment of the invention, see appendix. Figure 1 The battery compartment 110 is located in the middle of the float 10, the power compartment 160 is located in the stern of the float 10, and the electrical control box 20 is located in the upper part of the float 10.

[0024] In this embodiment of the invention, see appendix. Figure 5 The propulsion assembly 170 includes a pump-jet propulsion unit 171 and a guide shell 172 connected to each other. The pump-jet propulsion unit 171 is located at the tail end of the guide shell 172. The power compartment 160 has a first groove 161 with its opening facing downward and penetrating the stern of the float 10. The first groove 161 is provided with a first mounting bracket 180 and a cover 190. The first mounting bracket 180 is bonded to the first groove 161, for example, by adhesives such as structural adhesive or epoxy resin. The first mounting bracket 180 can be a metal bracket or a bracket made of other materials, providing stable support for the propulsion assembly 170, and bearing the thrust and vibration generated when the propulsion assembly 170 is working, and transmitting them to the float 10. The cover 190 is disposed opposite to the first mounting bracket 180, and the two form a receiving... The cavity houses the pump-jet propulsion unit 171 and the guide shell 172, thereby reducing underwater resistance and improving navigation efficiency. A cover 190 abuts against the outer surface of the pump-jet propulsion unit 171 and the guide shell 172 and is fixed to the pump-jet propulsion unit 171. The cover 190 prevents water from entering the power compartment 160 and provides support for the pump-jet propulsion unit 171 and the guide shell 172. The cover 190 is detachably connected to the pump-jet propulsion unit 171; for example, the cover 190 can be fixed to the pump-jet propulsion unit 171 by fasteners. The guide shell 172 is fixed to the first mounting bracket 180; for example, the guide shell 172 is detachably connected to the first mounting bracket 180 and fixed to the first mounting bracket 180 by fasteners, thus achieving the fixation and protection of the pump-jet propulsion unit 171 and the guide shell 172. This configuration serves two purposes. First, by designing the propulsion assembly 170 as a pump-jet propulsion unit 171 and a flow guide shell 172, and placing both within the receiving cavity formed by the first mounting bracket 180 and the cover 190 in the first groove 161, underwater resistance can be reduced, improving navigation efficiency. Second, by bonding the first mounting bracket 180 to the first groove 161, detachably connecting the cover 190 to the pump-jet propulsion unit 171, and detachably connecting the flow guide shell 172 to the first mounting bracket 180, the inspection and replacement of the pump-jet propulsion unit 171 and the flow guide shell 172 can be facilitated, thus improving the maintainability of the unmanned surface vessel.

[0025] In this embodiment of the invention, see appendix. Figure 6The guide housing 172 has a sealed cable pass-through hole 1721, which allows the power cable of the pump-jet propulsion unit 171 to pass through the guide housing 172 while ensuring the waterproof seal at the cable pass-through location. The sealed cable pass-through hole 1721 has a sealing structure, such as a rubber sealing ring or sealant, to prevent fluid from entering the interior of the guide housing 172. The first mounting bracket 180 is provided with a cable routing groove 181 and a clearance hole 182. The cable routing groove 181 runs along the accommodating portion of the first mounting bracket 180. The radially outward recess of the cavity provides a wiring location for the power cable of the pump-jet propulsion unit 171. A clearance hole 182 connects to the wiring trough 181 and the partition 100. The power cable of the pump-jet propulsion unit 171 passes through the sealed wiring hole 1721 and is electrically connected to the first electrical connection part 101 via the wiring trough 181 and the clearance hole 182. The clearance hole 182 provides a clearance location for the power cable from the wiring trough 181 to the first electrical connection part 101 of the partition 100. This arrangement, with the sealed wiring hole 1721 on the guide shell 172, effectively solves the waterproofing problem when the power cable exits the guide shell 172, ensuring the reliability of the electrical connection. The wiring trough 181 and clearance hole 182 on the first mounting bracket 180 provide a neat wiring location for the power cable, avoiding cable clutter, compression, or even wear inside the power compartment 160.

[0026] In this embodiment of the invention, see appendix. Figure 5 The cover 190 includes a base plate 191 and side connecting plates 192 connected to the base plate 191. The base plate 191 abuts against the outer surfaces of the pump-jet propulsion unit 171 and the guide shell 172. The side connecting plates 192 are plate-shaped or sheet-shaped structures, with two plates arranged opposite each other. The side connecting plates 192 are located within the first mounting bracket 180 and fixed to the pump-jet propulsion unit 171. With this configuration, the cover 190 is firmly connected to the pump-jet propulsion unit 171 through the base plate 191 and the side connecting plates 192, which enhances the fixing strength of the propulsion assembly 170 within the first groove 161, effectively resists water flow impact and vibration, thereby improving the operational stability of the unmanned surface vessel.

[0027] In this embodiment of the invention, the side connecting plate 192 has a through hole for avoiding the connection position, and a shielding plate 193 is provided at the lower end of the through hole for covering the through hole.

[0028] In this embodiment of the invention, see appendix. Figure 1 The power compartment 160 is located at the stern of the float 10. This configuration optimizes the hydrodynamic performance of the unmanned vessel and improves its navigation efficiency.

[0029] In this embodiment of the invention, see appendix. Figure 2 and Figure 7The battery compartment 110 includes a battery compartment body 120 and a cover 130. The battery compartment body 120 is used to accommodate the battery 150. The battery compartment body 120 has a first opening 1223. The first opening 1223 is provided with the cover 130. A first sealing gasket 140 is provided between the cover 130 and the first opening 1223. The cover 130 is connected to the side wall of the battery compartment body 120. A second electrical docking part 111 and a third electrical docking part 112 are both provided on the cover 130. This design, with the battery compartment 110 consisting of a battery compartment body 120 and a cover 130, and featuring a first opening 1223 and a first sealing gasket 140, effectively solves the waterproofing problem that the battery compartment 110 may face during the operation of the unmanned surface vessel, ensuring the operational safety and service life of the internal battery 150 and related electrical components. The cover 130 is connected to the side wall of the battery compartment body 120, allowing operators to easily open and close the battery compartment 110, thereby improving the efficiency of battery installation, maintenance, and replacement.

[0030] In this embodiment of the invention, see appendix. Figure 7 The battery compartment 120 includes a battery compartment body 121 and a hatch seal 122. The battery compartment body 121 has a hatch 1211 for accommodating a battery 150. The hatch seal 122 includes a sleeve 1221 and a flange 1222. The sleeve 1221 can abut against the peripheral wall of the hatch 1211. The flange 1222 is located at the end of the sleeve 1221 and can abut against the upper surface of the hatch 1211. A first opening 1223 is provided on the flange 1222. A first sealing gasket 140 is provided between the hatch cover 130 and the flange 1222. The outer contour dimension of the sleeve 1221 is smaller than the outer contour dimension of the flange 1222, and the contour dimension of the first opening 1223 is smaller than the contour dimension of the hatch 1211. This configuration, introducing a hatch seal 122 and designing the hatch seal 122 as a structure including a sleeve 1221 and a flange 1222, effectively seals the hatch 1211 of the battery compartment body 121. Specifically, the contact between the sleeve 1221 and the periphery of the hatch 1211 provides a first layer of structural sealing and support, while the contact between the flange 1222 and the upper surface of the hatch 1211, and bearing the first sealing gasket 140, forms a second layer of reliable sealing. This significantly improves the overall waterproof performance of the battery compartment 110, ensuring that the battery 150 and its internal electrical components are protected from liquid corrosion during long-term operation of the unmanned surface vessel, thereby extending the service life of the battery 150 and improving the overall reliability and safety of the unmanned surface vessel.

[0031] In this embodiment of the invention, see appendix. Figure 7The flange portion 1222 has a convex ring structure 1224, which extends along the axial direction of the first opening 1223 and away from the sleeve 1221. The convex ring structure 1224 surrounds the first opening 1223, and the first sealing gasket 140 can be fitted onto the convex ring structure 1224. This arrangement achieves the positioning of the first sealing gasket 140.

[0032] In this embodiment of the invention, see appendix. Figure 7 The battery compartment cover 130 includes a first cover plate 131, with a first side plate 132 hinged to the first end of the first cover plate 131. The first side plate 132 is connected to the outer wall of the battery compartment 120. The second end of the first cover plate 131 is snap-fitted to the outer wall of the battery compartment 120. A second electrical docking part 111 and a third electrical docking part 112 are both located on the first cover plate 131. This arrangement facilitates the opening and closing of the battery compartment 110 and facilitates daily maintenance. In addition, it provides reliable locking and sealing when closed, enhancing the waterproof effect of the battery compartment 110.

[0033] In this embodiment of the invention, see appendix. Figure 1 The float 10 has at least two components spaced apart along its width; a second mounting bracket 30 is fixed to the float 10 for mounting the electrical control box 20. This configuration, with the float 10 designed as at least two components spaced apart along its width, improves the lateral stability of the unmanned surface vessel; by providing the second mounting bracket 30, different electrical control boxes 20 can be replaced to achieve various surface operation functions.

[0034] In this embodiment of the invention, see appendix. Figure 8 The second mounting bracket 30 includes a first beam 310, a second beam 320, and a connecting beam 330. The first beam 310 has at least two beams and is spaced apart along the length direction of the float 10. Both ends of the first beam 310 are fixed to the float 10. The second beam 320 has at least two beams and is spaced apart along the width direction of the float 10. Both ends of the second beam 320 are fixed to the first beam 310. The electrical control box 20 is fixed to the second beam 320. The connecting beam 330 is parallel to the first beam 310, and both ends of the connecting beam 330 are fixed to the second beam 320. The connecting beam 330 is located between the second beams 320. With this configuration, the second mounting bracket 30 adopts a multi-beam structure, which significantly improves the overall rigidity and load-bearing capacity of the second mounting bracket 30. It can effectively distribute the weight of the electrical control box 20 and external impact force, and avoid local stress concentration. During the navigation of the unmanned surface vessel, it can effectively suppress vibration transmission, ensure a stable working environment for the electronic components inside the electrical control box 20, and thus extend the service life of the electronic components inside the electrical control box 20.

[0035] In this embodiment of the invention, see appendix. Figure 8 and Figure 9A connecting structure 340 is provided between the second mounting bracket 30 and the float 10. The connecting structure 340 includes a bearing 341, a bushing 342, and a mounting shaft 344. The bearing 341 is bonded to the upper surface of the float 10. A connecting plate 343 is fixed to the outer circumferential surface of the bushing 342 and is fixed to the first beam 310. The mounting shaft 344 fits inside the bushing 342. The lower end of the mounting shaft 344 has a flange 3441, which is fixed to the bearing 341. The upper end of the mounting shaft 344 is fastened to the bushing 342. This configuration allows for precise alignment and rapid assembly / disassembly of the second mounting bracket 30, greatly improving assembly / disassembly efficiency.

[0036] In this embodiment of the invention, see appendix. Figure 10 The electrical control box 20 has a fourth electrical docking section 201 and a fifth electrical docking section 202. For example, the fourth electrical docking section 201 can be a fourth waterproof aircraft plug, which is sealed and connected to the electrical control box 20. The fifth electrical docking section 202 can be a fifth waterproof aircraft plug, which is also sealed and connected to the electrical control box 20. The fourth electrical docking section 201 is electrically connected to the battery 150 via the second electrical docking section 111, that is, the fourth electrical docking section 201 is used to receive the power input from the battery 150. The fifth electrical docking section 202 is electrically connected to the propulsion assembly 170 of the power compartment 160 via the third electrical docking section 112 and the first electrical docking section 101, that is, the fifth electrical docking section 202 is used to output the power and control signals modulated by the electrical control box 20 to the propulsion assembly 170. With this configuration, the fourth electrical docking section 201 and the fifth electrical docking section 202 in the electrical control box 20 enable a quick and reliable connection between the electrical control box 20 and the battery 150 and the propulsion assembly 170.

[0037] In this embodiment of the invention, see appendix. Figure 11The inner wall of the electrical control box 20 is equipped with a motor driver 203 and a control board 204. The outer wall of the electrical control box 20 is equipped with a heat sink 205, a power switch 206, and an antenna. The area opposite the heat sink 205 and the motor driver 203 has heat dissipation holes 207, which penetrate the wall of the electrical control box 210. The motor driver 203, heat sink 205, control board 204, power switch 206, and antenna are all electrically connected to the fourth electrical docking part 201. The control board 204 is electrically connected to the fifth electrical docking part 202. It should be noted that the motor driver 203 includes a power conversion circuit, control logic, and protection mechanism, which can convert the electrical energy provided by the battery 150 into specific voltage and current waveforms required to drive the motor, thereby achieving fine adjustment of the speed and direction of the unmanned vessel. This configuration achieves several advantages. First, by strategically arranging the main heat-generating and control components, such as the motor driver 203 and control board 204, on the inner wall of the electrical control box 20, and placing components that need to interact with the external environment, such as the heat sink 205, power switch 206, and antenna, on the outer wall, the internal space of the electrical control box 20 is optimized and functionally partitioned. Second, the heat dissipation holes 207 located opposite the heat sink 205 and motor driver 203 provide an efficient and direct heat conduction path for the motor driver 203. This allows the heat generated by the motor driver 203 to be quickly transferred through the wall of the electrical control box 20 to the external heat sink 205, effectively preventing heat accumulation inside the electrical control box 20. This ensures the stability and reliability of key electronic components such as the motor driver 203 and control board 204 during long-term operation, extending the service life of the electrical control box 20. Furthermore, the external placement of the power switch 206 and antenna facilitates user operation and external communication.

[0038] In this embodiment of the invention, see appendix. Figure 8 and Figure 11The electrical control box 20 includes an electrical control box body 210 and a box cover 220. The bottom of the electrical control box body 210 is fixed to the float 10. The upper end of the electrical control box body 210 has a second opening 211. The second opening 211 is provided with the box cover 220. A second sealing gasket is provided between the box cover 220 and the second opening 211. The box cover 220 is connected to the side wall of the electrical control box body 210. The power switch 206 and the antenna are fixed to the box cover 220. The motor driver 203 is fixed to the inner side wall of the electrical control box body 210. The heat sink 205 is fixed to the outer side wall of the electrical control box body 210. The heat dissipation hole 207 penetrates the outer side wall of the electrical control box body 210. The control board 204 is fixed to the inner bottom wall of the electrical control box body 210. This design serves two purposes. First, the electrical control box 20 is designed as a box body 210 and a cover 220, with a second sealing gasket introduced to improve the overall waterproof performance of the electrical control box 20, ensuring that the electronic components inside the electrical control box 20 are protected from liquid corrosion during the operation of the unmanned surface vessel. Second, the power switch 206 and the antenna are integrated into the cover 220, facilitating operation and communication. The reasonable arrangement of the motor driver 203 and the control board 204, together with the heat sink 205 and the heat dissipation holes 207 penetrating the outer wall of the electrical control box 210, creates an efficient heat conduction path.

[0039] In this embodiment of the invention, see appendix. Figure 11 The heat dissipation hole 207 is filled with thermally conductive silicone 208 to conduct the heat generated by the motor driver 203 to the heat sink 205 for outward dissipation. This configuration, with the thermally conductive silicone 208 filling the heat dissipation hole 207, enhances the heat dissipation efficiency of the motor driver 203, effectively preventing the performance degradation of the motor driver 203 due to overheating, and ensuring the stability of the unmanned surface vessel's propulsion system.

[0040] In this embodiment of the invention, see appendix. Figure 8 The cover 220 includes a second cover plate 221, with a second side plate 222 hinged to the first end of the second cover plate 221. The second side plate 222 is connected to the outer wall of the electrical control box 210, and the second end of the second cover plate 221 is snap-fitted to the outer wall of the electrical control box 210. This design facilitates the opening and closing of the electrical control box 20 and facilitates daily maintenance. In addition, it provides reliable locking and sealing when closed, enhancing the waterproof effect of the electrical control box 20.

[0041] In this embodiment of the invention, the float 10 includes a shell and a cavity. The shell is made of carbon fiber reinforced resin matrix composite material, which has the characteristics of low density, high strength, water and corrosion resistance, and good watertightness. The shell is integrally vacuum-packed using a mold, resulting in high molding precision and structural consistency. The cavity is filled with foam, which can be 100% filled with PMI (polymethyl methacrylate) rigid closed-cell foam. The foam and the carbon fiber reinforced resin matrix composite material are bonded together with an adhesive, preferably epoxy resin, to form an integral load-bearing structure, significantly improving the shell's impact resistance and deformation resistance. Even if the shell is extensively damaged, the closed-cell foam can still provide sufficient buoyancy to ensure the unmanned vessel does not sink. It should be noted that the wall thickness of the shell 10 is between 0.4 and 0.8 mm, preferably 0.5 mm. This design simultaneously meets the requirements of lightweight, high strength, and high anti-sinking performance.

[0042] In this embodiment of the invention, see appendix. Figure 1 The bow of the float 10 has a V-shaped cross-section, while the stern has a rectangular longitudinal cross-section. This design, with its V-shaped bow structure and tapered bow to reduce drag, and its rectangular longitudinal cross-section to accommodate pump-jet propulsion, balances stability at low speeds with drag reduction at high speeds. This effectively reduces pitching and rolling caused by wave impacts, enhancing operational capabilities in harsh sea conditions.

[0043] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
