Description

Technical Field

[0002] With the increasing demand for ocean exploration and water operations, unmanned vessels are increasingly being used in environmental monitoring, resource exploration, and emergency rescue. However, in complex and changing marine environments, unmanned vessels are often threatened by various dynamic loads such as wind and wave impacts and collisions with floating objects, which places higher demands on the hull protection system. Among the current mainstream anti-collision structures, one type is the traditional solution using a rigid welded frame or integral buffer material. Its buffering performance has a fixed proportional relationship with the impact energy, and it is prone to structural damage due to stress concentration when responding to high-intensity instantaneous impacts. The other type is an improved solution using a single airbag unit. Although it can achieve local buffering, it may cause hull instability due to uneven pressure distribution.

Furthermore, existing cushioning units lack the ability to coordinate and respond to combined loads.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are merely partial embodiments of the present invention and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 In the first aspect, the present embodiment provides a modular quick-detachable airbag cushioning device for unmanned ships, which is suitable for unmanned ships. The airbag cushioning device includes: a base 1, multiple frame groups 2, multiple modular cushioning units 3, an air supply component 4 and a control component. The base 1 is arranged on the periphery of the unmanned ship; multiple frame groups 2 are distributed on the base 1 in a preset manner, each frame group 2 includes a fixing frame 21 and a fixing cover plate 22, the fixing frame 21 is arranged on the base 1, the fixing cover plate 22 is buckled on the fixing frame 21, and a storage cavity is provided in the fixing cover plate 22; each modular cushioning unit 3 is arranged in the storage cavity of a frame group 2, and the modular cushioning unit 3 includes a first airbag 31 and a second airbag 32, the first airbag 31 and the second airbag 32 are connected to each other; the gas delivery component 4 is arranged on the inner side of the base 1, and the gas delivery component 4 includes a gas delivery tank body 41, a gas delivery pipe group 42 and a valve group 43. The gas delivery pipe group 42 is arranged between the gas delivery tank body 41 and multiple modular buffer units 3. The gas delivery pipe group 42 is used to connect the gas tank body 41 to multiple modular buffer units 3 respectively. The gas delivery pipe group 42 is quickly disconnected from the modular buffer unit 3, and the valve group 43 is arranged at the connection between the gas delivery pipe group 42 and the modular buffer unit 3; the control component includes a control unit and a sensor group. The control unit is electrically connected to the sensor group and the valve group 43 respectively, and the sensor group is arranged on the modular buffer unit 3.

[0033] In this embodiment, the base 1 is a support structure fixed to the periphery of the unmanned boat. Made of lightweight, high-strength composite materials, it supports the combined weight of the frame assembly 2 and the buffer units. The frame assembly 2 comprises a mounting bracket 21 and a mounting cover 22. The mounting bracket 21 is rigidly connected to the base 1 via bolts, while the mounting cover 22 snaps into place with the mounting bracket 21. Its built-in storage cavity accommodates the modular buffer units 3.

[0034] The modular buffer unit 3 consists of a first airbag 31 and a second airbag 32, each interconnected. Preferably, the first and second airbags 31 and 32 are made of reinforced polyurethane material, exhibiting layered cushioning properties. The gas tank 41 in the gas delivery assembly 4 is a high-pressure gas storage device connected to each buffer unit via a gas delivery pipe assembly 42. The valve assembly 43 preferably utilizes an electromagnetically controlled structure to open and close the airway at the connection. The control assembly monitors the airbag pressure in real time via a sensor assembly, and the control unit adjusts the opening and closing state of the valve assembly 43 based on the sensor data.

[0035] The operating principle of this device can be understood as follows: when the unmanned vessel encounters an impact, the first airbag 31 first absorbs the initial kinetic energy. As the pressure increases, the gas enters the second airbag 32 through the air pipe assembly 42, achieving graded cushioning. A sensor assembly collects pressure data in real time, and the control unit dynamically adjusts the valve assembly 43 to maintain optimal cushioning pressure. When maintenance is required, any modular cushioning unit 3 can be individually removed using the quick-release connection structure of the air pipe assembly 42. The valve assembly 43 automatically cuts off the air flow to maintain the system's tightness, achieving graded dissipation of impact energy and independent maintenance of the modular units.

[0036] This embodiment realizes the graded absorption of impact energy through the dual-airbag connection design of the modular buffer unit 3, effectively alleviating the problem of pressure concentration in a single airbag. The air pipe group 42 that is quickly connected to the modular buffer unit 3 cooperates with the valve group 43, so that the replacement of a single modular buffer unit 3 does not require system pressure relief, which significantly improves maintenance efficiency. The coordinated work of the control component and the sensor group can dynamically adjust the status of the first airbag 31 and the second airbag 32 according to real-time pressure data to ensure adaptability to impacts of different intensities. This embodiment realizes the rapid disassembly and assembly function while maintaining airtightness, solving the problem of difficult maintenance of traditional structures. The modular design also facilitates the flexible adjustment of the number of buffer units according to the size of the unmanned ship, has better versatility and scalability, and improves the reliability and safety of unmanned ships operating in complex waters.

[0037] In some embodiments, the first airbag 31 and the second airbag 32 are arranged side by side in the storage cavity, and the gas pipe group 42 includes a first connecting branch pipe 421 and a first connecting main pipe 422. The first connecting branch pipe 421 is arranged between the first airbag 31 and the second airbag 32; the first connecting main pipe 422 is arranged between the first airbag 31 and the gas tank body 41; the valve group 43 includes a first gas valve, and the first gas valve is arranged at the connection between the first connecting main pipe 422 and the gas tank body 41.

[0038] In this embodiment, the first and second airbags 31 and 32 are buffer components arranged side by side within the storage cavity. They preferably have a wall thickness of 3-5 mm and a rated operating pressure of 0.2-1.5 MPa. Gas exchange between the two is achieved via a first connecting branch pipe 421. The first connecting main pipe 422 is preferably a high-pressure pipe made of aluminum alloy, connecting the first airbag 31 to the gas tank 41 for main gas flow. Preferably, the first gas valve utilizes a high-performance solenoid valve structure and is located at the junction of the first connecting main pipe 422 and the gas tank 41. The opening pressure is preset to 0.6 MPa, enabling precise regulation of the intake air flow. During operation, the impact force pressurizes the first airbag 31. When the pressure reaches a set threshold (i.e., 0.6 MPa), gas is diverted through the first connecting branch pipe 421 to the second airbag 32, achieving graded buffering.

[0039] This embodiment utilizes a parallel dual-airbag structure in conjunction with a preset pressure first air delivery valve to achieve progressive absorption of impact energy. When the pressure in the first airbag 31 exceeds a set threshold, the second airbag 32 is automatically activated for cushioning, effectively preventing single-stage overload. The synergistic effect of the first connecting main pipe 422 and the branch pipe simplifies the piping layout, while the rapid response of the solenoid valve ensures precise pressure regulation, improving overall cushioning efficiency and system reliability.

[0040] In some embodiments, the valve group 43 further includes a second gas delivery valve, which is disposed at the connection between the first connecting branch pipe 421 and the second airbag 32 .

[0041] In this embodiment, the second gas supply valve refers to a control component located at the junction of the first connecting branch pipe 421 and the second airbag 32. It utilizes the same high-performance solenoid valve structure as the first gas supply valve and has a rated operating pressure of 0.2-1.5 MPa. The second gas supply valve precisely regulates the flow of gas from the first airbag 31 to the second airbag 32. When the pressure in the first airbag 31 reaches 0.6 MPa, it opens in conjunction with the first gas supply valve, ensuring synchronized buffering. During operation, the second gas supply valve and the first gas supply valve work in tandem to maintain the pressure differential between the first and second airbags 31, 32 within a safe threshold, preventing unilateral overload.

[0042] This embodiment forms a dual-valve linkage mechanism by adding a second air supply valve, so that when the pressure of the first airbag 31 exceeds the limit, the second airbag 32 can be accurately triggered to intervene for buffering. The two valves work together to maintain an inter-stage pressure difference of 0.6MPa, which not only ensures the energy dissipation efficiency of the stage, but also prevents pressure imbalance between the airbags, significantly improving the system stability and response consistency.

[0043] In some embodiments, the number of first connecting branches 421 corresponds to the number of second airbags 32, the number of first connecting main pipes 422 corresponds to the number of first airbags 31, the number of first gas supply valves corresponds to the number of first connecting main pipes 422, and the number of second gas supply valves corresponds to the number of first connecting branches 421.

[0044] In this embodiment, the first connecting branch pipe 421 is a dedicated pipeline connecting the first airbag 31 and the second airbag 32. Preferably, it is made of nylon reinforced rubber hose, and its number is strictly matched with the second airbag 32 to ensure that each second airbag 32 can obtain an independent air path. The first connecting main pipe 422 is the main delivery pipeline between the gas tank body 41 and the first airbag 31. Preferably, it is made of aluminum alloy and is set corresponding to the number of first airbags 31. The first air delivery valve and the second air delivery valve are both high-performance solenoid valves, which are respectively configured corresponding to the number of main lines and branch lines to form a complete independent control unit group. During implementation, each component is set one by one to form a modular air path system, so that each modular buffer unit 3 can work independently and do not interfere with each other.

[0045] This embodiment constructs a completely independent multi-air path control system by strictly matching the number of pipelines and valves, so that each modular buffer unit 3 can achieve precise independent inflation and deflation control, avoiding the common pressure imbalance problem of multi-airbag systems, significantly improving the reliability of system operation and maintenance convenience, and ensuring that the buffering performance of each modular buffer unit 3 remains highly consistent.

[0046] In some embodiments, the gas delivery tank body 41 includes a first tank body and a second tank body, and the gas delivery pipe group 42 also includes: a second connecting branch pipe 423, a branch pipe 424 and a second connecting main pipe 425, the second connecting branch pipe 423 is arranged between the first tank body and the second tank body; the branch pipe 424 is arranged at the output end of the first tank body, and the branch pipe 424 is respectively connected to multiple first connecting main pipes 422; the second connecting main pipe 425 is arranged between the first tank body and the branch pipe 424; the valve group 43 includes a third gas delivery valve and a fourth gas delivery valve, the third gas delivery valve is arranged at the connection between the second connecting main pipe 425 and the branch pipe 424; the fourth gas delivery valve is arranged at the connection between the second connecting branch pipe 423 and the second tank body.

[0047] In this embodiment, the gas delivery tank 41 is a storage device that provides compressed gas for the airbag system. The first tank and the second tank are made of high-strength aluminum alloy. The gas between the two tanks is connected through the second connecting branch 423. The second connecting branch 423 is a dedicated pipeline connecting the two tanks. Preferably, it is made of nylon reinforced rubber to ensure the reliability of gas transmission. For details, please refer to Figure 4 , Figure 4 There is a magnified picture of A, specifically Figure 5 Shown in.

[0048] The branch pipeline 424 is a diversion structure provided at the output end of the first tank body, preferably made of aluminum alloy, and is used to evenly distribute the gas to multiple first connecting main pipes 422. The second connecting main pipe 425 is the main delivery pipe connecting the first tank body and the branch pipeline 424, and is made of high-pressure aluminum alloy pipe. The third gas supply valve is provided at the connection between the second connecting main pipe 425 and the branch pipeline 424, and the fourth gas supply valve is provided at the connection between the second connecting branch pipe 423 and the second tank body. Both are high-performance solenoid valve structures for accurately controlling the gas flow direction and pressure distribution. During implementation, the first tank body and the second tank body work together through the valve group 43. When the pressure of the first tank body is insufficient, the spare second tank body gas supply is automatically activated to ensure continuous and stable operation of the system.

[0049] This embodiment utilizes a dual-tank and multi-stage pipeline valve configuration to create a highly reliable gas supply system. When the gas supply pressure in the first tank drops, the fourth gas valve automatically opens to balance the pressures in the two tanks. Simultaneously, the third gas valve precisely adjusts the output pressure of branch pipeline 424 to ensure a stable gas supply for each modular buffer unit 3. This embodiment not only significantly improves the system's gas supply reliability and avoids the risk of single-point failure, but also achieves intelligent air pressure distribution through valve coordination, ensuring that each modular buffer unit 3 consistently maintains its optimal operating pressure, thereby ensuring the stability and consistent response of the airbag cushioning device under various operating conditions.

[0050] In some embodiments, the buffer device also includes a rotating clip 5 and a spring pin 6. The rotating clip 5 is arranged at the connecting port between the first connecting main pipe 422 and the first airbag 31; the spring pin 6 is arranged at the output end of the first airbag 31, and the rotating clip 5 is rotated to a first preset angle and is engaged with the spring pin 6.

[0051] In this embodiment, the rotating buckle 5 is a quick-connect component located between the first connecting pipe 422 and the connection port of the first airbag 31. It is made of high-strength stainless steel and has an arc-shaped structure. It locks when rotated to a first preset angle, preferably 90°. A spring pin 6, located at the output end of the first airbag 31 and made of highly elastic spring steel, forms a secure snap connection with the rotating buckle 5. This combined structure allows for quick assembly and disassembly between the air delivery pipe assembly 42 and the modular buffer unit 3. When the rotating buckle 5 is rotated to the first preset angle, the spring pin 6 automatically snaps into a locked position, ensuring the airtightness and stability of the connection.

[0052] This embodiment utilizes the coordinated design of a rotating buckle 5 and a spring pin 6 to establish a quick and reliable connection between the first connecting main pipe 422 and the first airbag 31. During installation, simply rotate the buckle 5 to a first preset angle to lock it, and during removal, rotate it in the opposite direction to release it. This simple and efficient operation not only ensures the airtightness of the pipe connection but also significantly improves maintenance convenience, making replacement or overhaul of the modular buffer unit 3 faster and more convenient, making it suitable for rapid maintenance needs in complex environments.

[0053] In some embodiments, the sensor group includes a plurality of first air pressure sensors and a second air pressure sensor. The first air pressure sensor is disposed in the first airbag 31 , and the second air pressure sensor is disposed in the second airbag 32 .

[0054] In this embodiment, the first air pressure sensor refers to an air pressure monitoring device disposed inside the first airbag 31. Preferably, it is encapsulated in 316L stainless steel and is used to monitor the pressure changes inside the first airbag 31 in real time. The second air pressure sensor is a similar monitoring device disposed inside the second airbag 32, having the same protection level and accuracy. Both the first air pressure sensor and the second air pressure sensor are precision pressure sensors with a measuring range covering the operating pressure range of the first airbag 31 and the second airbag 32. Real-time feedback of air pressure data ensures precise control of the system. During implementation, the sensor group works together to promptly trigger the corresponding control strategy when an air pressure anomaly is detected.

[0055] This embodiment achieves independent and accurate monitoring of the pressure of each level of airbags by setting a first air pressure sensor in the first airbag 31 and a second air pressure sensor in the second airbag 32, providing real-time air pressure data support for the system, ensuring that the working state of the airbags is controllable, and at the same time providing key parameter basis for intelligent valve control, effectively improving the response accuracy and reliability of the buffer system.

[0056] In some embodiments, the fixed cover plate 22 is configured to be made of a nitrile rubber-polyurethane composite material; a plurality of reinforcing ribs are arranged at intervals on the inner side of the fixed cover plate 22, and the shape of the reinforcing ribs is adapted to the shape of the first airbag 31 and the second airbag 32.

[0057] In this embodiment, the fixed cover plate 22 is a protective component made of a nitrile rubber-polyurethane composite material, offering excellent impact and wear resistance. The reinforcing ribs are spaced apart support structures inside the fixed cover plate 22. Their shape matches the contours of the first and second airbags 31, 32, enhancing overall structural rigidity and optimizing stress distribution. The support provided by the reinforcing ribs and the airbags effectively improves deformation resistance.

[0058] This embodiment uses a composite material fixed cover plate 22 with reinforcing ribs that match the shape of the airbag, which significantly improves the structural strength while ensuring lightweight, so that the protective device can effectively disperse the impact force and maintain a stable shape, thereby enhancing the overall cushioning performance.

[0059] In some embodiments, the shells of the first airbag 31 and the second airbag 32 are configured to be made of polyurethane elastic material; the interiors of the first airbag 31 and the second airbag 32 are filled with high-elasticity flame-retardant polyurethane foam material.

[0060] In this embodiment, the shells of the first airbag 31 and the second airbag 32 are made of polyurethane elastic material, which has excellent impact resistance and wear resistance, and the wall thickness is appropriately set to ensure structural strength; high-elasticity flame-retardant polyurethane foam material is filled inside the airbag to provide cushioning protection when the airbag is damaged, and at the same time has flame-retardant properties to ensure safe use, so that the airbag has both good elastic recovery ability and safety redundancy.

[0061] This embodiment uses a polyurethane elastic material shell combined with a flame-retardant foam filler to enable the first airbag 31 and the second airbag 32 to effectively absorb energy and quickly recover when subjected to impact, while still maintaining a buffering function in the event of accidental damage, significantly improving the reliability and safety of the anti-collision system.

[0062] In a second aspect, this embodiment further provides an unmanned boat, comprising an unmanned boat body 7 and an airbag cushioning device. The airbag cushioning device is the airbag cushioning device described in the first aspect and is arranged on the periphery of the unmanned boat body 7 .

[0063] In this embodiment, the unmanned boat body 7 is constructed from a lightweight, high-strength composite material, offering excellent impact and corrosion resistance. The airbag cushioning system, a multi-stage cushioning system as described in the first aspect, is secured to the periphery of the unmanned boat body 7 via a wraparound frame support structure, forming a complete protective system. This modular design facilitates quick assembly and disassembly for maintenance.

[0064] This embodiment forms all-round protection by arranging multi-stage airbag cushioning devices around the periphery of the unmanned boat. When a collision occurs, it can absorb impact energy step by step and effectively protect the hull structure. At the same time, the modular design facilitates maintenance and replacement, significantly improving the safety and practicality of the unmanned boat.

[0065] By adopting the above-mentioned technical solution, the present invention has the following beneficial effects compared with the prior art: through the dual-airbag connection design of the modular buffer unit 3, the graded absorption of impact energy is achieved, effectively alleviating the problem of pressure concentration in a single airbag. The coordinated work of the first airbag 31 and the second airbag 32 can automatically adjust the buffering force according to the impact intensity, ensuring adaptability to impacts of different intensities. Through the quick-release connection between the air supply pipe group 42 and the modular buffer unit 3 and the automatic shut-off function of the valve group 43, the replacement of a single modular buffer unit 3 does not require system pressure relief, which significantly improves maintenance efficiency. The provision of the rotating buckle 5 and the spring pin 6 further simplifies the disassembly and assembly process, making maintenance operations more convenient and efficient.

[0066] Furthermore, the coordinated work of the control component and the sensor group realizes the intelligent control of the system. The first air pressure sensor and the second air pressure sensor monitor the airbag pressure status in real time, providing accurate data support for the control unit, ensuring that the system can dynamically adjust the opening and closing status of the valve group 43 to maintain the optimal buffer pressure. The double tank design of the gas transmission tank body 41 and the multi-stage pipeline valve configuration build a highly reliable gas supply system and avoid the risk of single point failure. The reinforcing ribs of the fixed cover plate 22 are adapted to the shape of the airbag, effectively enhancing the overall structural rigidity. The use of a polyurethane elastic material shell and flame-retardant foam filler not only ensures the buffering performance but also improves safety redundancy.

[0067] The synergistic effect of the above technical solutions enables the device to achieve rapid disassembly and assembly while maintaining airtightness, solving the problem of difficult maintenance of traditional structures. At the same time, the modular design facilitates flexible adjustment according to the size of the unmanned boat, with better versatility and scalability, significantly improving the reliability and safety of unmanned boats operating in complex waters.
