Description

Technical Field

[0001] This utility model relates to the field of speedboat anti-collision technology, specifically an unmanned speedboat with anti-collision function. Background Technology

[0002] Fast attack craft are small in tonnage, high in speed, and highly maneuverable. They typically have a displacement of tens to hundreds of tons, a speed of 30 to 40 knots (some reaching 50 knots), and a range of 500 to 3000 nautical miles. They are armed, with some also equipped with 20 to 76 mm naval guns. Larger fast attack craft may also carry mines and depth charges. Their sensor systems include search, detection, weapon control, communication and navigation, and electronic warfare capabilities.

[0003] Modern speedboats widely utilize missile weapons, advanced miniaturized electronic equipment, high-power gas turbines, and hydrofoils and air cushion technologies, and are developing towards missile-like features, larger size, higher speed, and electronic capabilities. With technological advancements, speedboats are also moving towards unmanned operation for related tasks such as surveying, monitoring, information transmission, and combat.

[0004] Patent document CN111846136B discloses a marine anti-collision device. By installing an anti-collision plate on the outside of the ship's hull, it can prevent the ship's hull from directly contacting substances or objects in the seawater or reefs on the shore, thus avoiding damage to the ship's hull. At the same time, by using compression springs, in conjunction with positioning boxes, support rods, compression plates, and telescopic springs for buffering between the ship's hull and the anti-collision plate, it can buffer the force when impacting the ship's hull, preventing direct damage to the anti-collision plate, extending the service life of the device, and preventing direct impact damage to the ship's hull.

[0005] However, research has revealed certain drawbacks in the use of existing ship collision avoidance devices:

[0006] This marine collision avoidance device utilizes compression springs, along with positioning boxes, support rods, compression plates, and telescopic springs for buffering between the ship's hull and the collision avoidance plate, to achieve a buffering and collision avoidance effect. However, in actual application, due to the use of a large number of telescopic springs, algae, garbage, and other objects can easily accumulate during the movement of the speedboat or hull, thereby affecting the normal collision avoidance function of the hull or speedboat. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, this application provides an unmanned speedboat with anti-collision function. When the speedboat body equipped with an anti-collision seat impacts an object in front of it, the anti-collision seat contacts the obstacle first. Due to inertia, the speedboat body uses multiple second connecting arms to move around the corresponding first connecting arms, causing the speedboat body to apply pressure to the rubber sleeves on multiple protective structures in the horizontal direction. This causes the L-shaped frame to move towards the bottom from the side of the speedboat body, while the other end slightly tilts away from the bottom of the speedboat body from the outside of the anti-collision seat. This can force the speedboat body and the anti-collision seat to tend to move away from the obstacle, thereby achieving a certain buffering effect. Because the protective structure is close to the relevant structure of the speedboat body, it is basically on top of the anti-collision seat, and there is no technical effect of weeds accumulating outside the spring.

[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0009] An unmanned speedboat with anti-collision function includes a speedboat body, an anti-collision seat and a protective structure, wherein the anti-collision seat is located at the bottom of the bow of the speedboat body;

[0010] Multiple protective structures are provided, arranged between the inner wall of the anti-collision seat and the outer wall of the bow of the speedboat;

[0011] Multiple second connecting arms are provided on both sides of the bow of the speedboat, and multiple first connecting arms are provided on both sides of the inner walls of the anti-collision seat.

[0012] Each of the aforementioned protective structures includes a base, an L-shaped frame hinged to the top of the base, one end of the L-shaped frame away from the base extending into the inner side of the anti-collision seat and hinged to a metal sleeve, and a rubber sleeve fixedly connected to the outside of the metal sleeve.

[0013] The multiple second connecting arms located on the same side of the speedboat body and the multiple first connecting arms located on the same side of the anti-collision seat are hinged together. The corner of the L-shaped frame is located at the top of the base. When the speedboat body carrying the anti-collision seat hits an object in front of it, the anti-collision seat first contacts the obstacle. The speedboat body is subjected to pressure on the rubber sleeves on the multiple protective structures due to inertia, causing the end of the L-shaped frame close to the speedboat body to move to the bottom, while the other end is tilted from the outside of the anti-collision seat to the bottom away from the speedboat body, forcing the speedboat body and the anti-collision seat to have a tendency to move away from the obstacle.

[0014] Preferably, the first and second connecting arms, which are hinged to each other, are both V-shaped and maintain relative movement in the horizontal plane. The first and second connecting arms located on both sides of the speedboat body face opposite directions and are in a parallel state.

[0015] Preferably, a hydraulic push rod is provided between the outer wall of the anti-collision seat and the top of the L-shaped frame near the main body of the speedboat. The top of the hydraulic push rod is hinged to a base. Assembly bolts pass through the interior of the four corners of the base, and one end of the assembly bolt is threaded into the interior of the main body of the speedboat.

[0016] Preferably, the base has a storage slot on the surface near the speedboat body, and a pressure sensor is assembled and connected to the inner wall of the storage slot away from the speedboat body. After the mounting bolts are threadedly connected to the speedboat body, the pressure sensor is pressed against the outer wall of the speedboat body. The base is slidably connected to the outside of the four mounting bolts.

[0017] Preferably, a first strip groove is formed on the surface of the base away from the outer wall of the anti-collision seat, and inclined surfaces are machined on both sides of the base with respect to the L-shaped frame; the end of the L-shaped frame away from the main body of the speedboat is housed inside the first strip groove, and the side of the base away from the L-shaped frame is fixed to the outer wall of the anti-collision seat.

[0018] Preferably, a second slot is provided on the outer surface of the L-shaped frame near the main body of the speedboat, and an adjusting arm is hinged to the inner end of the second slot away from the main body of the speedboat, with one end of the adjusting arm hinged to the bottom of the hydraulic push rod.

[0019] Preferably, a flexible filter screen is fixedly connected to the inner wall of one end of the anti-collision seat near the main hull of the speedboat. One side of the flexible filter screen is fixed to the outer wall of the main hull of the speedboat, and the bottom of the flexible filter screen is separated from the bottom inner wall of the anti-collision seat.

[0020] Preferably, the rubber sleeve surfaces of the multiple L-shaped frames near the end of the speedboat body are all in contact with the outer side wall of the speedboat body, and the L-shaped frames and base are designed to mimic the shape of the speedboat body's head and the shape of the anti-collision seat.

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] Firstly, this utility model provides an unmanned speedboat with anti-collision function. When the speedboat body, equipped with an anti-collision seat, collides with an object in front of it, the anti-collision seat contacts the obstacle first. Due to inertia, the speedboat body uses multiple second connecting arms to move around the corresponding first connecting arms, causing the speedboat body to apply pressure to the rubber sleeves on multiple protective structures in the horizontal direction. This causes the L-shaped frame to move towards the bottom from the side of the speedboat body, while the other end slightly tilts away from the bottom of the speedboat body from the outside of the anti-collision seat. This forces the speedboat body and the anti-collision seat to tend to move away from the obstacle, thus achieving a certain buffering effect. Because the protective structure is close to the relevant structures of the speedboat body, it is basically on top of the anti-collision seat, and the situation of water plants accumulating outside the spring, as in the prior art, does not occur.

[0023] Secondly, this utility model provides an unmanned speedboat with anti-collision function. When the anti-collision seat first contacts the obstacle, the speedboat body is subjected to inertia and applies pressure to the rubber sleeves on multiple protective structures in the horizontal direction. The pressure is transmitted to the hydraulic push rod between the L-shaped frame and the speedboat body. The pressure sensor obtains the pressure value between the base and the speedboat body. The control system mounted on the speedboat body controls the hydraulic push rod to work. It can push the adjusting arm inside the second slot, so that the L-shaped frame continues to rotate around the hinge point. The end of the L-shaped frame away from the speedboat body pushes the speedboat body and the anti-collision seat away from the obstacle.

[0024] Thirdly, this utility model provides an unmanned speedboat with anti-collision function. By swaying the speedboat body back and forth on the horizontal plane, the speedboat body exerts pressure on the rubber sleeve due to inertia. When the rubber sleeve rolls down the outer wall of the speedboat body, it is hinged between the hydraulic push rod and the L-shaped frame by the adjusting arm inside the second groove on the L-shaped frame. During the process of the L-shaped frame rotating around the top of the base, it is not affected by the traction of the hydraulic push rod. Attached Figure Description

[0032] Example 1:

[0033] An unmanned speedboat with collision avoidance capabilities, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it includes a speedboat body 1, a crash seat 4 located at the bottom of the bow of the speedboat body 1, and multiple protective structures 2. Multiple second connecting arms 11 are provided on both sides of the bow of the speedboat body 1, and multiple first connecting arms 10 are provided on both sides of the inner walls of the crash seat 4.

[0034] Multiple protective structures 2 each include a base 202, an L-shaped frame 201 is hinged to the top of the base 202, one end of the L-shaped frame 201 away from the base 202 extends into the inner side of the anti-collision seat 4 and is hinged to a metal sleeve 204, and a rubber sleeve 205 is fixedly connected to the outside of the metal sleeve 204.

[0035] Among them, the rubber sleeves 205 of multiple L-shaped frames 201 near one end of the speedboat body 1 are all in contact with the outer side wall of the speedboat body 1. According to the shape of the head of the speedboat body 1 and the shape of the anti-collision seat 4, the L-shaped frame 201 and the base 202 are designed to mimic the shape. When multiple protective structures 2 are arranged between the inner side wall of the anti-collision seat 4 and the outer side wall of the head of the speedboat body 1, multiple protective structures 2 can be stably supported between the anti-collision seat 4 and the head of the speedboat body 1.

[0036] Secondly, multiple second connecting arms 11 located on the same side of the speedboat body 1 and multiple first connecting arms 10 located on the same side of the anti-collision seat 4 are respectively hinged together. By making the first connecting arms 10 and the second connecting arms 11 that are hinged together form a V-shape and maintain a relatively movable state in the horizontal plane, the first connecting arms 10 and the second connecting arms 11 located on both sides of the speedboat body 1 face opposite directions and are parallel to each other. This ensures that the anti-collision seat 4 is movable in the horizontal direction at the head of the speedboat body 1 and restricts its movement in the vertical direction.

[0037] Furthermore, by positioning the corner of the L-shaped frame 201 at the top of the base 202, when the speedboat body 1, equipped with the anti-collision seat 4, collides with an object in front of it, the anti-collision seat 4 contacts the obstacle first. The speedboat body 1, under inertia, applies pressure to the rubber sleeves 205 on the multiple protective structures 2, causing one end of the L-shaped frame 201 near the speedboat body 1 to move towards the bottom, while the other end tilts from the outside of the anti-collision seat 4 towards the bottom away from the speedboat body 1. This forces the speedboat body 1 and the anti-collision seat 4 to tend to move away from the obstacle, thereby achieving a certain buffering effect.

[0038] Furthermore, to prevent water plants and debris from becoming entangled on the exterior of the L-shaped frame 201 away from the main body of the speedboat 1 while it is traveling with the anti-collision seat 4, such as... Figure 2As shown, a first strip groove 5 is provided on the surface of the base 202 away from the outer wall of the anti-collision seat 4. By incorporating the end of the L-shaped frame 201 away from the speedboat body 1 into the first strip groove 5, the side of the base 202 away from the L-shaped frame 201 is fixed to the outer wall of the anti-collision seat 4. The base 202 is machined with inclined surfaces 6 on both sides of the L-shaped frame 201, so that the base 202 eliminates the sharp edges of the anti-collision seat 4 on the outside in the forward direction of the speedboat body 1, which can prevent water plants and garbage from moving with the anti-collision seat 4 to a certain extent.

[0039] In some examples, the speedboat body 1 is equipped with control system hardware and software, including audio module, sensor module, photoelectric module, motion module and AI processor, etc. Based on the control on the speedboat body 1, voice commands can be received through the audio module to achieve a certain degree of yacht motion control.

[0040] At the same time, the data from the sensor modules on the main body 1 of the speedboat can be combined and transmitted to the processor for comprehensive analysis, judgment and decision-making. The processor controls the action module and photoelectric module to respond in the form of navigation lights, warning lights and so on.

[0041] This utility model discloses an unmanned speedboat with anti-collision function. By setting an anti-collision seat 4 at the bottom of the bow of the speedboat body 1, and setting multiple protective structures 2 that conform to the shape and support the outer wall of the speedboat body 1 between the anti-collision seat 4 and the speedboat body 1, when the speedboat body 1 carrying the anti-collision seat 4 hits an object in front of it, the anti-collision seat 4 first contacts the obstacle. The speedboat body 1, under the action of inertia, uses multiple second connecting arms 11 to move around the first connecting arms 10 at the corresponding positions, so that the speedboat body 1 applies pressure to the rubber sleeves 205 on the multiple protective structures 2 in the horizontal direction. This causes the L-shaped frame 201 near the speedboat body 1 to move to the bottom, while the other end slightly tilts from the outside of the anti-collision seat 4 away from the bottom of the speedboat body 1. This can force the speedboat body 1 and the anti-collision seat 4 to tend to move away from the obstacle, thereby playing a certain buffering role and achieving the anti-collision effect at the bow of the speedboat body 1. Because the protective structures 2 are close to the relevant structures of the speedboat body 1, they are basically at the top of the anti-collision seat 4 (i.e., the high point position), and the situation of water plants accumulating outside the spring as in the prior art will not occur.

[0042] Example 2:

[0043] Based on Example 1, such as Figures 1-5 As shown, this embodiment is the specific structure of the protective structure 2. A hydraulic push rod 206 is provided between the outer wall of the anti-collision seat 4 and the top of the L-shaped frame 201 near the end of the speedboat body 1. The top of the hydraulic push rod 206 is hinged to the base 208. The four corners of the base 208 are all filled with mounting bolts 207.

[0044] In this way, by threading one end of the assembly bolt 207 into the interior of the speedboat body 1, one end of the hydraulic push rod 206 can be connected to the outer wall of the speedboat body 1.

[0045] Secondly, in order for the hydraulic push rod 206 to control the L-shaped frame 201 to move towards the bottom near the end of the speedboat body 1, the L-shaped frame 201 rotates around its hinge point with the base 202, causing the anti-collision seat 4 and obstacles to actively move away, such as... Figure 4 and Figure 5 As shown, a storage slot 9 is provided on the surface of the base 208 near the speedboat body 1. A pressure sensor 8 is assembled and connected to the inner wall of the storage slot 9 away from the speedboat body 1. After the mounting bolts 207 are threadedly connected to the speedboat body 1, the pressure sensor 8 is pressed against the outer wall of the speedboat body 1, keeping the base 208 in a sliding connection to the outside of the four mounting bolts 207. When the anti-collision seat 4 contacts the obstacle first, the speedboat body 1 is subjected to inertia, causing the speedboat body 1 to apply pressure to the rubber sleeves 205 on the multiple protective structures 2 in the horizontal direction. The hydraulic push rod 206 between the L-shaped frame 201 and the speedboat body 1 is simultaneously pressed, transmitting the pressure to the hydraulic push rod 206, so that the pressure sensor 8 obtains the pressure value between the base 208 and the speedboat body 1.

[0046] At this time, with the help of the control system hardware and software installed in the speedboat body 1, the sensor data is transmitted to the processor for comprehensive analysis, judgment and decision-making. The processor then controls the hydraulic push rod 206 to work, so that the hydraulic push rod 206 presses down the L-shaped frame 201, causing the L-shaped frame 201 to rotate around its hinge point with the base 202 at a larger angle, so that the end of the L-shaped frame 201 away from the speedboat body 1 tilts to one side, pushing the anti-collision seat 4 away from the obstacle.

[0047] Meanwhile, the top of the speedboat body 1 can be protected by airbags, which are part of existing ship collision avoidance technology.

[0048] Furthermore, to prevent the hydraulic push rod 206 from being too rigid between the speedboat body 1 and the L-shaped frame 201 during the back-and-forth swaying of the speedboat body 1, thus affecting the smooth rotation of the L-shaped frame 201 around the top of the base 202 after the rubber sleeve 205 is subjected to inertial pressure from the speedboat body 1, such as... Figure 2 and Figure 5 As shown, a second strip groove 7 is provided on the outer surface of the L-shaped frame 201 near the end of the speedboat body 1. An adjusting arm 203 is hinged to the inner end of the second strip groove 7 away from the speedboat body 1. By hinged one end of the adjusting arm 203 to the bottom of the hydraulic push rod 206, when the speedboat body 1 applies pressure to the rubber sleeve 205 due to inertia, the L-shaped frame 201 remains in a state of rotating around the top of the base 202, while the adjusting arm 203 exits from the inside of the second strip groove 7 through two hinge points, without affecting the normal movement of the L-shaped frame 201.

[0049] Meanwhile, during the process of the hydraulic push rod 206 controlling the movement of the L-shaped frame 201, the adjusting arm 203 is first controlled to return to the inside of the second strip groove 7, and then the L-shaped frame 201 is controlled to continue to rotate around its hinge point with the base 202.

[0050] In some examples, to prevent aquatic organisms and debris from entering the inner side of the anti-collision seat 4, such as... Figure 1 and Figure 5 As shown, a flexible filter 3 is fixedly connected to the inner wall of the anti-collision seat 4 near the hull of the speedboat body 1. By fixing one side of the flexible filter 3 to the outer wall of the speedboat body 1, the bottom of the flexible filter 3 is separated from the bottom inner wall of the anti-collision seat 4. When the speedboat body 1 is horizontally swaying inside the anti-collision seat 4, foreign objects can be blocked by the protective structure 2.

[0051] This utility model discloses an unmanned speedboat with anti-collision function. A hydraulic push rod 206 is installed between the end of the L-shaped frame 201 near the speedboat body 1 and the outer wall of the speedboat body 1. The hydraulic push rod 206 is connected to the L-shaped frame 201 through an adjusting arm 203. When the anti-collision seat 4 first contacts the obstacle, the speedboat body 1 is subjected to inertia, causing the speedboat body 1 to apply pressure to the rubber sleeves 205 on multiple protective structures 2 in the horizontal direction. The hydraulic push rod 206 between the L-shaped frame 201 and the speedboat body 1 is simultaneously pressed, and the pressure is transmitted to the hydraulic push rod 206. The pressure sensor 8 obtains the pressure value between the base 208 and the speedboat body 1. The control system mounted on the speedboat body 1 controls the hydraulic push rod 206 to work, which can push the adjusting arm 203 inside the second slot 7, so that the L-shaped frame 201 continues to rotate around the hinge point, and the end of the L-shaped frame 201 away from the speedboat body 1 pushes the speedboat body 1 and the anti-collision seat 4 to actively move away from the obstacle.

[0052] Meanwhile, as the speedboat body 1 sways back and forth on the horizontal plane, the speedboat body 1 exerts pressure on the rubber sleeve 205 due to inertia, and the rubber sleeve 205 rolls to the bottom at the outer side wall of the speedboat body 1. Meanwhile, the L-shaped frame 201 is not affected by the traction of the hydraulic push rod 206 as it rotates around the top of the base 202 due to the adjusting arm 203 inside the second strip groove 7.

[0053] It should be noted that the control system hardware and software mounted on the main body 1 of the speedboat, including the audio module, sensing module, photoelectric module, motion module and AI processor, as well as the related processing and control technologies, all use known technologies. For details, please refer to Patent Document 1, Publication No. CN101727760B, Patent Document 2, Publication No. CN217271096U, etc. This is the application of related technologies of the control system, which forms the basis of the technology of this application and will not be elaborated further.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
