Description

Technical Field

[0001] This application relates to emergency rescue equipment, and in particular to a rescue air cushion module and its assembly. Background Technology

[0002] Existing rescue air cushions are widely used in emergency rescue scenarios such as firefighting and high-altitude operations. Their core structure is made of high-strength, airtight materials, and they adopt an integrated inflation design, combined with a rapid inflation device and a cushioning layer. These air cushions are mostly rectangular or circular in fixed dimensions, and are rapidly inflated using high-pressure gas cylinders or electric pumps. They are suitable for fall rescue scenarios in standard open areas, providing uniform cushioning protection through their integrated structure.

[0003] However, the existing fixed-size, one-piece design of rescue air cushions has significant shortcomings: their terrain adaptability is extremely poor, and they cannot flexibly adjust their shape and size according to the spatial characteristics of complex rescue sites such as narrow alleys, corner areas, or irregular terrain. When facing non-standard sites, one-piece air cushions often fail to deploy effectively, resulting in insufficient rescue coverage and thus reducing the success rate of rescues.

[0004] How to make rescue air cushions have the ability to flexibly deform to adapt to complex terrain has become an urgent technical problem to be solved. Utility Model Content

[0005] The technical problem this application aims to solve is: how to enable rescue air cushions to have flexible deformation capabilities to adapt to complex terrain.

[0006] To address the aforementioned technical problems, this application provides a rescue air cushion module and its assembly.

[0007] In a first aspect, this application provides a rescue air cushion module, including a square airbag with an inflation port. The square airbag is hexahedral, and hook-and-loop fasteners are provided on the four sides of the square airbag. The rescue air cushion module is detachably connected to another rescue air cushion module via the hook-and-loop fasteners.

[0008] In one embodiment, at least one side of the square airbag is provided with an elastic band.

[0009] In one embodiment, the square airbag is also provided with straps for securing adjacent rescue air cushion modules.

[0010] In one embodiment, the strap is provided with a tension adjustment ring, which is used to adjust the length of the strap in order to adjust the tension of the strap.

[0011] In one embodiment, a quick-release buckle is provided on either side of the square airbag, and the quick-release buckle has a toothed pattern.

[0012] In one embodiment, at least one side of the square airbag is provided with a fluorescent positioning point, and the fluorescent positioning points of any rescue airbag module are at the same height.

[0013] In one embodiment, the inner sides of the four sides of the square airbag are provided with annular reinforcing ribs.

[0014] In one embodiment, a sealing strip is provided on the inner side of the inflation port, which is used to seal the inflation port after the square airbag is inflated.

[0015] A second aspect of this application provides an assembly of rescue air cushion modules, comprising a plurality of rescue air cushion modules provided in the first aspect of this application, wherein adjacent rescue air cushion modules are detachably connected by hook and loop fasteners on square airbags.

[0016] In one embodiment, the assembly further includes a high-pressure gas cylinder or air pump, which is connected to the inflation port of the rescue air cushion module for inflating any of the rescue air cushion modules.

[0017] Compared with the prior art, the rescue air cushion module and its assembly according to the embodiments of this application have the following advantages:

[0018] By designing the rescue air cushion as multiple independent square airbag modules, each module features hook-and-loop fasteners on its sides, enabling detachable connections between modules and overcoming the limitations of fixed dimensions in traditional one-piece rescue air cushions. In actual rescue scenarios, rescuers can flexibly assemble different numbers and arrangements of air cushion modules according to the spatial characteristics of narrow alleys, corner areas, or irregular terrain. They can freely adjust the shape and size of the rescue air cushion to fully conform to complex terrain, effectively expanding the rescue coverage area and significantly improving the success rate of rescues in complex environments. Simultaneously, the modular design facilitates transportation and storage, and allows for quick replacement of damaged modules, reducing usage and maintenance costs and enhancing the practicality and economy of the rescue air cushion.

[0026] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] In the description of this application, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not used to describe a specific structure. It should be understood that such terms are interchangeable where appropriate so that embodiments of this application can be implemented in structures other than those illustrated or described. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. For example, a product or device comprising a series of components or units is not necessarily limited to those explicitly listed, but may also include other components or units not explicitly listed but inherent to these products or devices.

[0028] In emergency rescue fields such as fire fighting and high-altitude operations, existing rescue air cushions, with their high-strength airtight materials, integrated inflatable structure, rapid inflation devices, and cushioning layers, have become crucial equipment for ensuring personnel safety. These air cushions are mostly rectangular or circular in shape and are rapidly inflated using high-pressure gas cylinders or electric pumps. In standard rescue scenarios with flat terrain and open spaces, their integrated structure provides stable cushioning for falling personnel.

[0029] However, in actual rescue operations, the fixed-size, monolithic design has revealed significant drawbacks. When the rescue site is a narrow alley, a winding corner, or a rugged terrain, the existing air cushion cannot be adjusted to meet the shape and size requirements of the complex space. This makes it difficult to fully deploy in non-standard locations, preventing the formation of an effective rescue area and greatly limiting rescue efficiency and success rate.

[0030] To solve this problem, such as Figure 1As shown in the preferred embodiment of this application, a rescue air cushion module 10 may include a square airbag 101. The square airbag 101 has an inflation port 102. The square airbag 101 is a hexahedron. The four sides of the square airbag 101 are provided with hook and loop fasteners 103. The rescue air cushion module 10 and another rescue air cushion module 10 are detachably connected by hook and loop fasteners 103.

[0031] By designing the rescue air cushion into multiple square airbag modules 101, and using the hook and loop fasteners 103 on the side to achieve detachable connection between the modules, different numbers and arrangements of air cushion modules can be freely spliced ​​according to the spatial characteristics of the rescue site.

[0032] Because the hook and loop fastener 103 does not require distinguishing between the front and back, any two sides can be attached and fixed. For example, in rescue operations in narrow alleys, the modules can be spliced ​​together into a long strip. In irregular terrain, they can be spliced ​​into irregular shapes, allowing the rescue air cushion to fully conform to the terrain, effectively expanding the rescue coverage area and significantly improving the success rate of rescues in complex environments.

[0033] Furthermore, in some scenarios, the vertical and horizontal assembly methods can be combined to achieve flexible construction of three-dimensional space. For example, in high-rise building collapse rescues, horizontal assembly expands the horizontal coverage area of ​​the air cushion, while multiple layers of air cushion modules are stacked vertically to form a three-dimensional protection system with a multi-layered buffer structure, effectively improving the cushioning effect for people falling from heights. In deep well rescues, vertical assembly allows the air cushion to adapt to the vertical space of the well, while horizontal assembly adjusts the lateral dimensions, ensuring a tight fit against the well wall and preventing trapped personnel from slipping, thus providing comprehensive safety for the rescue.

[0034] The modular design makes the rescue airbag more convenient to transport and store. Compared with the integral airbag, the individual square airbag 101 module is small in size and light in weight, making it easy to carry and move.

[0035] In actual rescue operations, if a module is damaged, rescuers can quickly disassemble and replace it with a new one, without having to replace the entire air cushion. This reduces usage and maintenance costs and improves the continuous availability of the rescue equipment. Even if the damaged module is not replaced in time, the remaining modules can still provide most of the protection and will not lose their effectiveness as quickly as a traditional full-length inflatable air cushion.

[0036] To improve the effectiveness of rescue efforts, such as Figure 1 As shown in one embodiment of this application, an elastic band 104 is provided on at least one side of the square airbag 101.

[0037] After multiple modules are assembled, adjacent elastic bands 104 can be quickly connected via buckles to form a continuous handle system. For example... Figure 3In the combined device 1, which consists of 9 modules, 4 rescuers can simultaneously lift 4 sets of elastic bands 104 to maintain the balance of the air cushion during transport.

[0038] Furthermore, when a falling object impacts the rescue air cushion module 10, the elastic band 104 first undergoes elastic deformation, converting the impact force into elastic potential energy. By absorbing some of the impact energy, the elastic band 104 reduces the instantaneous pressure on the square airbag 101 of the rescue air cushion module 10, improving the rescue success rate and the service life of the rescue air cushion module 10. Besides being held by hand, the elastic band 104 can also be attached to various anchor points such as surrounding pillars and beams, similarly providing impact resistance.

[0039] After use, the elastic band 104 can also be used to transport the rescue air cushion module 10.

[0040] In order to effectively improve the assembly strength between different rescue air cushion modules 10, in one embodiment of this application, the square airbag 101 may also be provided with straps for binding adjacent rescue air cushion modules 10.

[0041] The straps wrap around the edges of the modules to counteract the tendency of the Velcro to peel off, making the adjacent rescue air cushion modules 10 fit together more securely.

[0042] In addition, in one embodiment of this application, the strap is provided with a tension adjustment ring, which is used to adjust the length of the strap in order to adjust the tension of the strap.

[0043] Rescuers can quickly and precisely control the length of the straps using this adjusting ring, thereby flexibly adjusting the strap tension. This allows for convenient assembly on flat terrain and enhances the stability of module connections in complex environments (such as strong winds or sloping surfaces), preventing connection failures from hindering rescue efforts. The adjusting ring can adjust tension in real time to maintain optimal restraint; it is easy to operate and requires no specialized tools.

[0044] In one embodiment, a quick-release buckle is provided on any side of the square airbag 101, and the quick-release buckle is provided with a toothed pattern.

[0045] The quick-release buckles and serrated texture on the side of the square airbag 101, together with the hook-and-loop fastener 103, form a "dual locking" synergistic mechanism. The hook-and-loop fastener 103, with its flexible fit, enables rapid positioning and initial assembly of the modules, while the quick-release buckles provide rigid locking through the serrated texture. When the buckles are pressed and locked, the serrated texture and corresponding slots form a high-strength mechanical engagement, enhancing the anti-separation force between modules. This design utilizes the convenience of hook and loop fasteners for rapid networking in emergencies, while the serrated structure of the buckles compensates for the loosening of the connection in vibration and impact scenarios.

[0046] In one embodiment, at least one side of the square airbag 101 is provided with a fluorescent positioning point, and the fluorescent positioning points of any rescue air cushion module 10 are at the same height.

[0047] In low-light or dark rescue scenarios, the continuous illumination of fluorescent positioning points provides rescuers with a clear visual reference. When multiple rescue air cushion modules are spliced ​​together, fluorescent positioning points at the same height automatically form a horizontal baseline. This not only facilitates quick alignment of modules to ensure splicing accuracy, but also allows for a visual display of the overall outline and boundaries of the air cushion in complex terrain through illuminated lines.

[0048] In one embodiment, the inner sides of the four sides of the square airbag 101 are provided with annular reinforcing ribs 105. When the airbag is inflated, the annular reinforcing ribs 105, by constraining the radial expansion of the airbag, convert the tension generated by the internal air pressure into the axial tensile force of the ribs, making the pressure distribution on the surface of the airbag uniform and facilitating the fitting of different rescue airbag modules 10. When multiple modules are spliced, the coaxial arrangement of the annular reinforcing ribs 105 forms an integral support frame, making the corners of the rescue airbag modules 10 right angles or close to right angles, increasing the effective contact area of ​​adjacent rescue airbag modules 10.

[0049] In one embodiment, a sealing strip is provided on the inner side of the inflation port 102. The sealing strip is used to seal the inflation port 102 after the square airbag 101 is inflated. When gas is injected into the airbag through the inflation port 102, the internal air pressure gradually increases. The sealing strip is squeezed outward by the air pressure and tightly adheres to the inner wall of the inflation port 102 and the contact surface of the air nozzle, forming a self-sealing effect of "the greater the air pressure, the tighter the seal".

[0050] Meanwhile, the elastic resilience of the sealing strip ensures that the inflation port 102 remains airtight after multiple insertions and removals. The flexible contact of the strip also reduces wear during the insertion and removal of the air nozzle, extending the service life of the inflation port 102. It is especially suitable for rescue scenarios that require rapid inflation and continuous pressure maintenance.

[0051] like Figure 3 As shown, this application also provides a corresponding assembly device 1 for a rescue air cushion module 10, which may include a plurality of rescue air cushion modules 10 in any embodiment of this application. Among the plurality of rescue air cushion modules 10, adjacent rescue air cushion modules 10 are detachably connected by hook and loop fasteners 103 on the square airbag 101.

[0052] The combined device 1 provided in this application is formed by splicing together several rescue air cushion modules 10 with hook and loop fasteners 103, creating a flexible rescue system with high terrain adaptability. Figure 3 These can be combined to form a large-area rescue air cushion, while... Figure 4 They can be assembled into long, narrow rescue air cushions to adapt to confined terrain, as in another embodiment, such as... Figure 5As shown, rescue air cushions can be assembled to fit corners and cope with different rescue environments. This application will not list all other possible combinations; appropriately modifying the combination style to adapt to different rescue environments also falls within the scope of protection of this application.

[0053] Adjacent rescue air cushion modules 10 can be quickly and detachably connected via hook and loop fasteners 103. They can be assembled into long strips of coverage in narrow alleys or combined into polygonal buffer surfaces in irregular terrain, increasing the rescue coverage area several times over compared to traditional integral air cushions.

[0054] The combined device 1 continues the lightweight advantage of the single module, while the flexible connection of the Velcro allows for rapid deployment to form a large buffer area, and can also be flexibly adapted to narrow spaces by disassembling individual modules.

[0055] Further coordination with the elastic rope for handling and adjustment, and the structural support of the ring-shaped reinforcing rib 105, achieves full-process optimization from "emergency deployment" to "precise protection", significantly improving rescue efficiency and safety in complex environments.

[0056] It is understood that the combined device 1 in this application includes all the technical features of the rescue air cushion module 10, and therefore the embodiments and beneficial effects of the rescue air cushion module 10 in this application are applicable to the combined device 1 in this application.

[0057] In one embodiment, the combined device 1 may further include a high-pressure gas cylinder or a gas pump, which is connected to the inflation port 102 of the rescue air cushion module 10 for inflating any of the rescue air cushion modules 10.

[0058] In summary, this application provides a rescue air cushion module 10 and its assembly device 1. The working process is as follows: the modules are quickly spliced ​​together by the hook and loop fastener 103 of the square airbag 101, and the connection rigidity is enhanced by quick-release buckles and toothed texture. The elastic rope and strap system realizes the handling and tension adjustment. The annular reinforcing rib 105 ensures the airbag's resistance to deformation. The sealing strip ensures the dynamic sealing of the inflation port 102. The assembly device 1 is connected to the inflation port 102 through a high-pressure gas cylinder or air pump to realize the synchronous inflation of multiple modules. The fluorescent positioning point assists in the precise deployment in low light environment. Finally, it can be flexibly spliced ​​into different shapes of buffer structures according to the terrain of the rescue site.

[0059] This design breaks through the fixed size limitations of traditional integral air cushions, enabling rescue air cushions to adapt to complex terrains, shortening deployment time, improving terrain fit, and increasing impact energy absorption rate. At the same time, the modular design reduces maintenance costs, significantly improving rescue efficiency and safety in complex environments, and providing an innovative solution for emergency rescue equipment that combines flexibility, reliability, and practicality.

[0060] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
