Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a multi-stage impact-resistant hull and ship. Background Technology

[0002] A yacht is a high-end durable consumer product for water recreation. It integrates functions such as navigation, sports, entertainment, and leisure, meeting the needs of individuals and families to enjoy life. The essential characteristic of a yacht as a recreational tool distinguishes it from high-speed ships and tourist passenger ships as transportation tools.

[0003] When navigating at sea, ship collisions are prone to occur due to factors such as crew negligence in lookout, low visibility, or equipment malfunction. In collisions between ships of similar tonnage, the vessel struck from the side usually suffers more severe damage. Furthermore, small and medium-sized yachts typically do not have watertight compartments, making them more likely to sink quickly if severely damaged in a side impact. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a multi-stage impact-resistant hull and yacht. The hull is equipped with multi-stage buffers, which can effectively absorb impact forces, reduce the degree of damage, and minimize the risk of sinking.

[0005] The first aspect of the present invention protects a multi-level impact-resistant hull, the hull comprising an inner base plate and an outer plate disposed outside the inner base plate, the outer plate being easily broken upon impact, and a side sandwich layer being formed between the inner base plate and the outer plate. The side interlayer is provided with a first buffer assembly, a second buffer assembly, and a third buffer assembly capable of absorbing impact force, wherein the first buffer assembly is close to the outer panel.

[0006] Furthermore, the outer panel is a fiberglass panel, a wood panel, or a composite panel; the composite panel is formed by bonding a fiberglass panel and a wood panel together.

[0007] Furthermore, the first buffer assembly includes several first movable plates and a second movable plate disposed opposite to the first movable plates, wherein the first movable plates are disposed in contact with the outer plate; The first movable plate and the second movable plate are connected by an optical axis guide rail; A multi-link structure is also provided between the first movable plate and the second movable plate, which enables the adjacent first movable plate to move away from the inner substrate when one of the first movable plates approaches the inner substrate.

[0008] Furthermore, the multi-link structure includes a limiting block fixedly mounted on the second movable plate, and a connecting rod slidably mounted on the limiting block, the connecting rod being able to move toward or away from the second movable plate; The two ends of the connecting rod are respectively hinged to two conversion structures, and each conversion structure is simultaneously hinged to two adjacent first moving plates. The conversion structure enables the two adjacent first moving plates to move in opposite directions.

[0009] Furthermore, the conversion structure includes a first support rod, one end of which is hinged to a first movable plate, the other end of which is rotatably connected to one end of a second support rod via a first rotating shaft, and the other end of which is hinged to the second movable plate; The conversion structure also includes a fourth support rod, one end of which is hinged to another adjacent first movable plate, and the other end of which is rotatably connected to one end of a third support rod via a second rotating shaft, and the other end of the third support rod is hinged to one end of the connecting rod; One end of the first rotating shaft is extended and rotatably connected to the rod body of the third support rod; One end of the second rotating shaft is extended and rotatably connected to the rod body of the first support rod; The first rotating shaft is close to the second rotating shaft.

[0010] Furthermore, the second buffer assembly includes a cylinder fixedly disposed on the inner base plate and a piston rod movably disposed in the cylinder, wherein one end of the piston rod protruding from the cylinder is fixedly disposed on the first buffer assembly; A second magnet is fixedly installed inside the cylinder, and the second magnet is fixed to the bottom surface of the cylinder. A first magnet is installed at one end of the piston rod inside the cylinder. The first magnet and the second magnet are arranged opposite each other, and the first magnet and the second magnet repel each other.

[0011] Furthermore, both the first magnet and the second magnet are neodymium iron boron permanent magnets.

[0012] Furthermore, the third buffer assembly includes a cable, a first pulley disposed on the first buffer assembly, and a second pulley disposed on the inner base plate; One end of the cable is fixedly mounted on the first buffer assembly, and the other end of the cable passes through the first pulley and the second pulley and is connected to the protrusion on the other side of the hull. When the first pulley moves closer to the second pulley, the protruding part can extend away from the hull, increasing the stability of the hull.

[0013] Furthermore, the protruding member includes a frame, a plate, and a fixing rib fixed to the inner base plate; The two ends of the frame are respectively hinged to the fixing rib and the plate; One end of the cable is rotatably connected to the frame, and the plate can extend when the cable pulls the frame.

[0014] Furthermore, a sliding groove is provided on the side wall of the fixing rib, and a sliding bearing is provided at the bottom end of the plate. The sliding bearing is configured to cooperate with the sliding groove. When the cable pulls the frame, the sliding bearing rises along the sliding groove.

[0015] A second aspect of the present invention protects a yacht comprising the hull described in any one of the preceding claims, wherein the hull is provided with a deck and a cabin.

[0016] Beneficial Effects: This invention, by incorporating easily breakable outer plating, allows the hull to absorb impact force through fragmentation upon impact, reducing the inward transmission of impact force and minimizing damage to the hull interior. By installing a first, second, and third buffer assembly within the side layers, all three can absorb impact force. The first buffer assembly is located close to the outer plating, while the second and third buffer assemblies can be located in the same or different layers. After the outer plating breaks, the first buffer assembly absorbs the impact force first, followed by the second, then the third; alternatively, the second and third buffer assemblies may absorb the impact force simultaneously. Compared to a single-layer hull, the hull of this invention can absorb impact force in multiple layers, resulting in a larger total absorbed impact force. Furthermore, the multi-layered design extends the impact time, reducing the damage to the hull interior from massive instantaneous impact forces. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figures 1-14 The first aspect of this invention protects a multi-stage impact-resistant hull, the hull 1 including an inner base plate 12 and an outer plate 11 disposed outside the inner base plate 12. The outer plate 11 is easily broken upon impact, and a side sandwich is formed between the inner base plate 12 and the outer plate 11. The outer plate 11 can be selected as a thin plate; or lines can be engraved on the surface of the outer plate 11 to reduce its strength. This ensures that the outer plate 11 remains intact during normal operation and can break and absorb energy under small impact forces.

[0021] The side interlayer is provided with a first buffer assembly 13, a second buffer assembly 14, and a third buffer assembly 15 capable of absorbing impact force, wherein the first buffer assembly 13 is close to the outer panel 11. The second buffer assembly 14 and the third buffer assembly 15 can be arranged sequentially from the outside to the inside; the second buffer assembly 14 and the third buffer assembly 15 can also be set in the same layer.

[0022] This invention utilizes an easily breakable outer plating 11. When the hull 1 is impacted, the outer plating 11 breaks to absorb the impact force, reducing the inward transmission of the impact force and minimizing damage to the interior of the hull 1. A first buffer assembly 13, a second buffer assembly 14, and a third buffer assembly 15 are installed within the side layers, all three capable of absorbing the impact force. The first buffer assembly 13 is located close to the outer plating 11, while the second and third buffer assemblies 14 and 15 can be located in the same or different layers. After the outer plating 11 breaks, the first buffer assembly 13 absorbs the impact force first, followed by the second buffer assembly 14, and then the third buffer assembly 15; alternatively, the second and third buffer assemblies 14 and 15 may absorb the impact force simultaneously. Compared to a single-layer hull, the hull 1 of this invention can absorb impact force in multiple layers, resulting in a larger total absorbed impact force. Furthermore, the multi-layered design extends the impact time, reducing the damage to the interior of the hull 1 caused by the massive instantaneous impact force.

[0023] In one specific embodiment, the outer panel 11 is a fiberglass sheet, a wood panel, or a composite panel; the composite panel is formed by bonding a fiberglass sheet and a wood panel. Fiberglass sheets are commonly used as the outer panel material for the hull 1. The advantages of fiberglass sheets 11 are significant lightweighting, and the brittleness of fiberglass sheets can be increased by adjusting the resin ratio, making them easier to break upon impact. Wood panels have the advantages of low cost and fragility; as the outer panel 11, they ensure the normal navigation of the hull 1 and effectively break as a sacrificial layer upon impact. Composite panels effectively overcome the insufficient water resistance and corrosion resistance of wood panels. By selecting a thin layer of fiberglass attached to the outer layer of the wood panel, the water resistance and corrosion resistance of the wood panel can be effectively improved, while also meeting the requirement of fragility for the outer panel 11.

[0024] refer to Figure 4 and Figure 7 In one specific embodiment, the first buffer assembly 13 includes a plurality of first movable plates 131 and a second movable plate 133 disposed opposite to the first movable plates 131, wherein the first movable plates 131 are disposed in contact with the outer plate 11; The first movable plate 131 and the second movable plate 133 are connected by an optical axis guide rail 134; A multi-link structure 132 is also provided between the first movable plate 131 and the second movable plate 133. The multi-link structure 132 makes the adjacent first movable plate 131 move away from the inner substrate 12 when one of the first movable plates 131 approaches the inner substrate 12.

[0025] In this embodiment, by setting a multi-link structure 132, adjacent first movable plates 131 can move in opposite directions. The advantages are: when the hull 1 suffers an external impact, the impacting object first strikes the outer plate 11, breaking it. After the outer plate 11 breaks, the impacting object strikes one of the first movable plates 131, causing it to move inward. At this time, the two adjacent first movable plates 131 move outward. Since the impacting object only strikes one first movable plate 131, the outer plate 11 at the positions of the two adjacent first movable plates 131 remains intact. The multi-link structure 132 crushes the unbroken outer plate 11 from the inside, further consuming the impact force and prolonging the impact time. The multi-link structure 132 can change the direction of the impact force of the impacting object, allowing it to act again on the unbroken outer plate 11. This prolongs the impact time and reduces the destructive force of the impacting object; secondly, it consumes the impact force by breaking the intact outer plate 11 again, further reducing the destructive force.

[0026] refer to Figure 5 and Figure 7In one specific embodiment, the multi-link structure 132 includes a limiting block 1326 fixedly mounted on the second movable plate 133. A connecting rod 1325 is slidably mounted on the limiting block 1326, and the connecting rod 1325 can move towards or away from the second movable plate 133. Specifically, the upper surface of the limiting block 1326 is provided with a square sliding groove, and the bottom wall in the middle of the connecting rod 1325 is provided with a protrusion. The protrusion cooperates with the square sliding groove, so that the connecting rod 1325 moves in a direction perpendicular to the plane of the second movable plate 133.

[0027] The two ends of the connecting rod 1325 are respectively hinged to two conversion structures. Each conversion structure is simultaneously hinged to two adjacent first moving plates 131. The conversion structure enables the two adjacent first moving plates 131 to move in opposite directions.

[0028] In this embodiment, by setting the connecting rod 1325, two adjacent conversion structures can move on the same horizontal plane, thereby enabling the conversion structure to drive the first moving plate 131 to move in the direction perpendicular to the outer plate 11. This facilitates the first moving plate 131 to strike the outer plate 11 perpendicularly, making the outer plate 11 easier to break and absorb the impact force.

[0029] refer to Figure 8 In one specific embodiment, the conversion structure includes a first support rod 1321, one end of which is hinged to a first movable plate 131, and the other end of which is rotatably connected to one end of a second support rod 1322 via a first rotating shaft 1323. The other end of the second support rod 1322 is hinged to a second movable plate 133.

[0030] The conversion structure also includes a fourth support rod 1327, one end of which is hinged to an adjacent first movable plate 131. The other end of the fourth support rod 1327 is rotatably connected to one end of a third support rod 1324 via a second pivot 1328. The other end of the third support rod 1324 is hinged to one end of a connecting rod 1325. One end of a first pivot 1323 extends and is rotatably connected to the body of the third support rod 1324. One end of a second pivot 1328 extends and is rotatably connected to the body of the first support rod 1321. The first pivot 1323 is located close to the second pivot 1328.

[0031] by Figure 8 For example, when the leftmost first movable plate 131 moves inward, the second support rod 1322 and the first support rod 1321 move closer together, and the first rotating shaft 1323 moves to the right. The first rotating shaft 1323 is on the third support rod 1324 and close to the second rotating shaft 1328, which will cause the third support rod 1324 and the fourth support rod 1327 to move away from each other, thereby causing the middle first movable plate 131 to move outward.

[0032] In this embodiment, a conversion structure is provided for two purposes: First, it changes the direction of the impact force. Regardless of the direction from which the impacting object strikes the first moving plate 131, the impact force is converted into a force perpendicular to the direction of the second moving plate 133, allowing the first moving plate 131 to move vertically. This enables the subsequent second buffer assembly 14 and third buffer assembly 15 to better perform their buffering functions. Second, it dissipates energy. The force of the impacting object striking the first moving plate 131 is transmitted to the conversion structure, driving multiple support rods or rotating shafts to perform complex linkages such as translation, swinging, and rotation. This process itself dissipates a portion of the impact force, thus playing a buffering role.

[0033] refer to Figure 9 In one specific embodiment, the second buffer assembly 14 includes a cylinder 143 fixedly mounted on the inner base plate 12 and a piston rod 141 movably mounted within the cylinder 143. One end of the piston rod 141 protruding from the cylinder 143 is fixedly mounted on the first buffer assembly 13. The cylinder 143 is preferably made of copper, and the cylinder 143 and piston rod 141 have a conventional cylinder structure, with the piston rod 141 capable of extending and retracting into and out of the cylinder 143.

[0034] A second magnet 144 is fixedly installed inside the cylinder body 143 and is fixed to the bottom surface of the cylinder body 143. A first magnet 142 is installed on one end of the piston rod 141 inside the cylinder body 143.

[0035] The first magnet 142 and the second magnet 144 are arranged opposite to each other, and the first magnet 142 and the second magnet 144 repel each other.

[0036] This embodiment, by setting up a piston rod 141 and a cylinder 143, serves two purposes: First, it provides a limiting mechanism, allowing the second moving plate 133 to move along a direction perpendicular to the inner base plate 12. This facilitates the design of a buffer structure to handle forces acting on the second moving plate 133. Second, it integrates buffering. Firstly, a first magnet 142 and a second magnet 144 are provided; they repel each other, and this repulsive force provides support under normal conditions, keeping the second moving plate 133 essentially stationary relative to the inner base plate 12. When the second moving plate 133 is impacted and moves inward, the piston rod 141 moves into the cylinder 143, causing the first magnet 142 to approach the second magnet 144. The repulsive force between them provides effective buffering. Furthermore, when the first magnet 142 moves within the cylinder 143, it generates eddy currents. According to Lenz's law, the magnetic force generated by these eddy currents prevents the first magnet 142 from moving, thus also buffering the impact force. Since the cylinder body 143 is preferably made of copper, the first magnet 142 can generate eddy currents on the cylinder body 143 when it moves, but it will not be attracted to the cylinder body 143, thus ensuring normal operation.

[0037] In one specific embodiment, both the first magnet 142 and the second magnet 144 are neodymium iron boron (NdFeB) permanent magnets. NdFeB permanent magnets are known as the "king of magnets." They possess extremely high magnetic energy product and coercivity. Using NdFeB permanent magnets in the buffer of the hull 1 allows a relatively small volume of NdFeB permanent magnets to generate a large magnetic force.

[0038] refer to Figures 10-12 In one specific embodiment, the third buffer assembly 15 includes a cable 153, a first pulley 151 disposed on the second moving plate 133, and a second pulley 152 disposed on the inner base plate 12.

[0039] One end of the cable 153 is fixed to the second movable plate 133, and the other end of the cable 153 passes through the first pulley 151 and the second pulley 152 and is connected to the protrusion on the other side of the hull 1. Depending on actual needs, one end of the cable 153 can also be fixed to the piston rod 141. Moving the piston rod 141 pulls the cable 153 to operate.

[0040] When the first pulley 151 approaches the second pulley 152, the cable 153 becomes taut. This tautness allows the extender to extend away from the hull 1, increasing the stability of the hull 1. Specifically, in small yachts, one end of the cable 153 can be fixed to the piston rod 141. During the movement of the piston rod 141, the cable 153 is pulled taut to drive the extender out. In large yachts, considering the larger pulling force, one end of the cable 153 needs to be fixed to the second moving plate 133 to achieve stable tension. Of course, in either case, a margin can be set in the cable 153. When the second moving plate 133 moves slightly towards the inner base plate 12, the cable 153 remains taut; only a large movement of the second moving plate 133 towards the inner base plate 12 will cause the cable 153 to become taut, pulling the extender out.

[0041] The impact of the object entering the space between the second movable plate 133 and the inner base plate 12 indicates a significant impact force. In this embodiment, the cable 153 and the extender are used; pulling the cable 153 also absorbs the impact force. Furthermore, the extender extends from opposite sides, meaning the impact point is on the left and the extender plate extends from the right. This design increases buoyancy, effectively preventing the yacht from capsizing under a large impact force and maximizing the safety of the people on board.

[0042] refer to Figure 11 and Figure 12 In one specific embodiment, the protruding member includes a frame 155, a plate 156, and a fixing rib 154 fixed on the inner base plate 12.

[0043] The two ends of the frame 155 are hinged to the fixing rib 154 and the plate 156, respectively.

[0044] One end of the cable 153 is rotatably connected to the frame 155. A metal ring can be installed at the end of the cable 153 near the frame 155, and a metal rod is installed on the frame 155. The metal ring is fitted onto the metal rod to achieve the rotatable connection. When the cable 153 pulls the frame 155, the plate 156 can extend.

[0045] The cable 153 pulls the frame 155 upward, causing the frame 155 to swing upward around the top axis, which in turn causes the plate 156 to extend.

[0046] Because the protruding part is located at the bottom of the hull 1, the space is limited. In this embodiment, a frame 155 and a plate 156 are hinged together to form a folding structure, which is suitable for confined spaces. The frame 155 can also convert the vertical force of the cable 153 into a horizontal force to push out the plate 156, effectively achieving the extension.

[0047] refer to Figure 12 In one specific embodiment, a sliding groove 1541 is provided on the side wall of the fixing rib 154, and a sliding bearing 1561 is provided at the bottom end of the plate 156. The sliding bearing 1561 is configured to cooperate with the sliding groove 1541. When the cable 153 pulls the frame 155, the sliding bearing 1561 rises along the sliding groove 1541.

[0048] In this embodiment, by setting a sliding bearing 1561 and a sliding groove 1541, the bottom end of the plate 156 moves upward and the top end of the plate 156 moves diagonally downward, allowing the vertical plate 156 to adjust its posture in a short time and achieve horizontal extension. Furthermore, during the extension process, the plate 156 applies significant pressure to the inner wall of the outer plate 11, and the top edge of the plate 156 exerts significant pressure on the outer plate 11, causing the outer plate 11 to break smoothly and allowing the plate 156 to extend smoothly. Of course, depending on the actual situation, sharp metal points can be provided on the outer surface of the plate 156 to increase the destructive force on the outer plate 11.

[0049] refer to Figures 10-14 In one specific embodiment, the hull 1 is provided with a block component 157. The block component 157 includes a first block 1571 and a second block 1572. The cable 153 includes a first main cable 1531 disposed on a first side of the hull 1 and a second main cable 1536 disposed on a second side. The first side and the second side are opposite sides.

[0050] One end of the first main rope 1531 is fixed to the second movable plate 133 on the first side. The other end of the first main rope 1531 passes over the first pulley 151 and the second pulley 152 on the first side and is fixed to one side of the first block 1571. One end of the first auxiliary rope 1532 and one end of the third auxiliary rope 1534 are fixed to the other side of the first block 1571. The other end of the first auxiliary rope 1532 passes through the second block 1572, passes over the first pulley 151 and the second pulley 152 on the second side, and is connected to the frame 155 on the second side. The other end of the third auxiliary rope 1534 passes through the second block 1572, passes over the first pulley 151 and the second pulley 152 on the second side, and is connected to the frame 155 on the second side.

[0051] One end of the second main rope 1536 is fixed to the second movable plate 133 on the second side. The other end of the second main rope 1536 passes over the first pulley 151 and the second pulley 152 on the second side and is fixed to one side of the second block 1572. One end of the second auxiliary rope 1533 and one end of the fourth auxiliary rope 1535 are fixed to the other side of the second block 1572. The other end of the second auxiliary rope 1533 passes through the first block 1571, passes over the first pulley 151 and the second pulley 152 on the first side, and is connected to the frame 155 on the first side. The other end of the fourth auxiliary rope 1535 passes through the first block 1571, passes over the first pulley 151 and the second pulley 152 on the first side, and is connected to the frame 155 on the first side.

[0052] This embodiment, by setting up block component 157, can convert a single pulling force on one side into a bidirectional pulling force on the other side, which can pull two plates 156 to extend. The advantage of this is that it can absorb the impact force to a certain extent, achieving cushioning. This embodiment also sets the position of the cable 153. Taking the figure as an example, the first main cable 1531 is also positioned between the first secondary cable 1532 and the third secondary cable 1534. This allows the two plates 156 on the second side to extend at intervals. The advantage of this position setting is improved stability. For example, if an impacting object strikes the first side of the hull 1, two plates 156 extend at intervals on the second side corresponding to the impact position, effectively increasing buoyancy in number and further enhancing stability in position. This effectively prevents the hull 1 from capsizing and maximizes personnel safety.

[0053] refer to Figures 1-3 The second aspect of this invention protects a yacht comprising a hull 1 according to any of the above embodiments, with a deck 2 and a cabin 3 provided on the hull 1. Impacts to the hull 1 typically occur near the waterline, and a first buffer assembly 13, a second buffer assembly 14, and a third buffer assembly 15 can be installed near the waterline. The remaining areas are the normal hull to enhance overall stability. The yacht in this embodiment can absorb a large amount of impact force at multiple stages and has the advantage of preventing capsizing.

[0054] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
