Description

Technical Field

[0001] This invention relates to an inflatable structure and its application, and more particularly to a deformable roof inflatable structure and its application as a small inflatable boat tent in a luggage compartment. Background Technology

[0002] With the explosive growth of self-driving camping, light travel, and water recreation, users are increasingly demanding integrated equipment that allows them to travel the world in one vehicle.

[0003] Existing roof boxes are all injection-molded ABS or PC hard shells with a fixed size. When not in use, they occupy a large amount of family storage space, and disassembly and assembly require two people. Meanwhile, portable inflatable boats are carried separately, requiring additional air pumps, paddles, and propulsion units. The overall weight of these items is large, and their function overlaps with that of the roof box, resulting in a triple waste of materials, costs, and storage. Inflatable tents face the same problem and still require separate solutions for transportation.

[0004] Researchers discovered that there is currently no integrated solution that combines a single inflatable frame with detachable functional modules to achieve the transformation between a suitcase, a small inflatable boat, and a tent. Therefore, the market urgently needs a transformable device with a shared basic structure, pluggable functional modules, and minimal storage volume. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a deformable roof inflatable structure and its application as a small inflatable boat tent in a luggage compartment.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a deformable roof inflatable structure, including a functional module package and a main airbag body that is symmetrical along the long axis and has an upper opening;

[0007] The main airbag is formed by the front facade, rear facade, left facade, right facade and bottom. The front facade extends backward and upward at an angle of 60°–75° relative to the bottom to form a frontal slope. The left facade and right facade are connected to the front facade by a downward transition along the upper edge of the front side of the main airbag. The rear facade, left facade and right facade are upright structures.

[0008] The outer perimeter of the main airbag body near the upper opening is covered with a ring; the functional module package is selectively installed or removed from the ring to form a roof box, a small inflatable boat, or an outdoor tent.

[0009] Furthermore, the functional module package, in conjunction with the main airbag body, forms components for a roof trunk, a small inflatable boat, or an outdoor tent.

[0010] Furthermore, the components that work in conjunction with the main airbag to form the roof box include:

[0011] The PV soft sealing cap has hanging parts on its edge that correspond one-to-one with the rings to close the upper opening;

[0012] A circumferential elastic tension rope is located around the periphery of the PV soft sealing cover and is tightened with the ring to form a dustproof and waterproof compartment;

[0013] Furthermore, the components that work together with the main airbag to form the roof box also include a reinforcement airbag. The reinforcement airbag is placed inside the main airbag and, after inflation, it presses against the left and right facades to improve the roof box's anti-sag rigidity.

[0014] Furthermore, the components that work together with the main airbag to form a small inflatable boat include:

[0015] The port side float-reinforced airbag is detachably fixed to the outside of the port facade and locked with an additional webbing via a ring;

[0016] The starboard pontoon reinforced airbag is detachably fixed to the outside of the starboard elevation and locked with an additional webbing via a ring;

[0017] Tail-end propulsion interface plate, embedded in the rear facade for quick installation of electric thrusters or propellers;

[0018] The detachable tail fin is inserted into a pre-set T-slot on the rear of the bottom surface to provide directional stability;

[0019] The bow pull ring is located on the forward facade for mooring or towing when docked.

[0020] Furthermore, the components that work together with the main airbag to form a small inflatable boat also include:

[0021] The windshield has a hanging bracket on its edge, which is connected to the upper front edge of the left facade, the upper front edge of the right facade, and the hanging bracket on the front facade.

[0022] Furthermore, the components that work together with the main airbag to form an outdoor tent include: The keel support frame is connected to the main airbag body at its bottom via a hanging device; The tent cover is placed over the keel support frame and forms a closed support space with the main airbag. The tent cover has a transparent observation window and the bottom perimeter of the tent cover is detachably connected to the main airbag via a hanging device.

[0023] The luggage compartment includes a deformable roof inflatable structure.

[0024] Small inflatable boat, including the deformable roof inflatable structure as claimed in claim 1.

[0025] The tent includes the deformable roof inflatable structure as claimed in this claim.

[0026] This invention discloses a deformable inflatable roof structure and its application as a small inflatable boat tent in a luggage compartment. By providing a unified, inflatable main airbag platform, combined with a set of ingenious modular interfaces and functional components, it systematically solves a series of problems related to materials, cost, storage, and convenience associated with traditional split-type outdoor gear. Its core innovation lies in replacing fragmented functionalities with a highly integrated system design, achieving a revolutionary breakthrough of "three uses in one airbag." It provides an ideal solution for users seeking an efficient and lightweight outdoor lifestyle, possessing significant market competitiveness and promotional value. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1As shown, the present invention discloses a deformable roof inflatable structure, the core of which is a main airbag 1. This main airbag is symmetrical along its long axis, has an upper opening, and is formed by a front facade 11a, a rear facade 11c, a left facade 11b, a right facade 11d, and a bottom facade 11e. The front facade 11a extends rearward and upward relative to the bottom facade 11e at an angle of 60°–75°, preferably 60°, 70°, and 75°, forming a streamlined frontal ramp. The upper front edges of the left facade 11b and the right facade 11d are smoothly connected to the front facade 11a via a swooping transition zone. The rear facade and the left and right facades are upright structures, forming a stable and aerodynamically efficient cabin. A D-ring 2 is evenly arranged around the outer periphery of the upper opening of the main airbag 1, used for quickly installing or removing various functional module packages via attachments, thereby achieving multiple functional forms such as a roof trunk, a small inflatable boat, or an outdoor tent.

[0036] [Example 1] Rooftop luggage compartment configuration

[0037] like Figure 2 As shown, in this embodiment, the deformable roof inflatable structure is configured as a roof luggage compartment. Before use, the independent main airbag 1 is inflated through the inflation port, causing it to quickly expand and form a sturdy cabin structure. The sloping design of the front facade 11a effectively reduces wind resistance, and the sloping transition of the left and right facades provides better airflow guidance. The overall shape is suitable for roof installation.

[0038] Next, install the luggage-specific components. First, take the PVC soft sealing cap 41, whose edge is pre-fitted with several hanging elements 3, corresponding one-to-one with the D-rings 2 on the outer periphery of the main airbag opening. During installation, first align the sealing cap 41 with the center of the upper opening, then use the circumferential elastic tension rope 42 to sequentially fasten it into the D-rings 2 along its periphery and tighten it, forming a well-sealed dustproof and waterproof compartment. This sealing cap has good flexibility and weather resistance, and can adapt to complex outdoor environments.

[0039] To further secure the airbag body to the roof, two straps are used. The straps have hooks at both ends, allowing for quick attachment to the D-rings 2 on the left facade 11b and right facade 11d (not shown in the diagram), and tightening via adjusters to firmly secure the main airbag body 1 to the roof crossbar. The straps are made of high-strength polyester material, possessing sufficient tensile strength and durability to ensure they do not loosen during high-speed driving.

[0040] To enhance the overall rigidity of the suitcase and prevent sagging due to load or wind, a reinforcing airbag 7 can be placed inside the main airbag body 1. When inflated, this reinforcing airbag provides lateral support between the left and right facades, significantly improving the structure's bending resistance. In actual use, the addition of the reinforcing airbag results in minimal deformation of the suitcase when bearing standard luggage weight, meeting the needs of long-distance travel.

[0041] After use, simply release the gas from the main airbag and the reinforcing airbag to roll up the entire structure for storage. The rolled-up volume is significantly smaller than a traditional hard-shell suitcase, and the weight is also kept low, making it easy to store in the trunk or storage compartment. The entire process requires no tools and can be completed by one person in minutes, greatly improving ease of use and space utilization.

[0042] This embodiment fully embodies the design concept of "one bag for multiple uses". Through simple module switching, it realizes the function of a roof box and solves the pain points of traditional hard-shell boxes being cumbersome to disassemble and assemble and inconvenient to store.

[0043] [Example 2] Configuration of a small inflatable boat

[0044] like Figure 3 and Figure 4 As shown, in this embodiment, the deformable roof inflatable structure is transformed into a small inflatable boat. The basic shape of the main airbag 1 remains unchanged, and the slope of its front facade 11a naturally becomes the bow, which is conducive to breaking through the water and reducing wave resistance.

[0045] First, install the hull reinforcement components. The port side buoy reinforcement airbag 51 and the starboard side buoy reinforcement airbag 52 are attached to the outer sides of the port elevation 11b and starboard elevation 11d of the main airbag hull, respectively. These two buoys are cross-locked to the D-ring 2 on the main airbag hull via additional webbing 57, forming a stable catamaran structure that significantly increases buoyancy and lateral stability. The buoys are made of a TPU composite material similar to that of the main airbag hull, possessing excellent water pressure resistance and puncture resistance.

[0046] A stern propulsion interface plate 53 is embedded in the center of the aft facade 11c. This plate has pre-embedded threaded inserts for quick installation of an electric propeller or small propeller to provide propulsion. The power supply equipment can be placed in a waterproof compartment inside the main airbag body to ensure electrical safety. A T-slot is pre-set at the rear of the bottom surface 11e for inserting a detachable tail fin 54. The tail fin is made of ABS engineering plastic and automatically locks in place after insertion, providing good directional stability for the vessel and reducing the turning radius.

[0047] A bow towing ring 55 is provided on the forward facade 11a at the bow, facilitating mooring, towing, or docking operations. In addition, a forward windshield 56 is optional, with a hanging body 3 on its edge, which connects to the D-ring 2 on the port, starboard, and forward facades to form a low water deflector, effectively reducing splashing into the cabin during navigation and improving passenger comfort.

[0048] In actual water tests, the inflatable boat easily carried two adults and some equipment. Its moderate freeboard and speed meet the needs of recreational fishing and lake excursions. The boat's stable structure and simple operation make it especially suitable for family outdoor activities.

[0049] After use, the gas in the main airbag and floats is released, and accessories such as the propeller and tail fin are disassembled. All components can be stored in the main airbag or in the vehicle's tool kit, greatly saving space. This embodiment demonstrates the flexibility and creativity of achieving waterborne functions through modular expansion of the same basic structure.

[0050] [Example 3] Outdoor Tent Configuration

[0051] In this embodiment, the deformable roof inflatable structure is used as an outdoor tent. The main airbag 1 is placed on a flat ground and kept inflated, serving as the foundation and lower enclosure structure of the tent.

[0052] The core of the tent's function lies in the keel support frame 62 and the tent cover 61. The keel support frame is composed of several foldable carbon fiber poles, making it lightweight yet strong. Its bottom is connected to the main airbag body 1 via a hanging device 3, which serves as a positioning sleeve on the inner side of the left facade 11b and the right facade 11d, quickly assembling the main framework of the tent. Subsequently, the tent cover 61 is placed over the keel support frame, and the hanging devices 3 at its bottom perimeter are fastened to the D-rings 2 around the opening on the main airbag body 1, forming a complete and enclosed living space.

[0053] like Figure 6 As shown, the tent cover is made of lightweight waterproof fabric, with transparent observation windows 63 on the top and side walls, made of environmentally friendly TPU material, which allow light to pass through while being waterproof, and are equipped with zippers for easy opening and closing. A Velcro sealing strip is also provided between the bottom edge of the tent and the opening on the main air bladder, forming a complete enclosure of the main air bladder to further prevent insects or rainwater from entering.

[0054] To enhance the tent's stability in outdoor environments, the D-ring 2 along the lower edge of the main airbag can be connected via ground peg webbing 63, and the ground pegs can be driven into the ground, effectively resisting strong winds. Tests show that this structure exhibits minimal displacement under moderate wind conditions, demonstrating its safety and reliability.

[0055] The interior is spacious enough to accommodate 1-2 people, with a moderate ridge height for comfortable sitting and standing. Lighting equipment can be suspended at night using the keel support nodes without additional support. The entire assembly process is simple and quick, requiring no professional knowledge or tools.

[0056] When packing up, first remove the tent pegs and tent cover, release the gas from the keel support frame and main air bladder, and roll up all the components together. The total volume and weight are significantly lower than traditional tent combinations, greatly improving the portability and efficiency of outdoor activities.

[0057] The core innovation of this invention—a deformable inflatable roof structure and its application as a luggage compartment, small inflatable boat, and tent—lies in its overturning of the traditional model of dedicated and independently carried outdoor equipment. Through a highly integrated modular design, it successfully solves the three major industry pain points mentioned in the background technology: material redundancy, cost redundancy, and storage redundancy. Its solution and creativity are mainly reflected in the following three aspects: A systematic solution to the "three redundancies" problem creatively designs a universal main airbag as the sole basic load-bearing structure. This main airbag is reused in various applications, including the cabin of a suitcase, the hull of an inflatable boat, and the foundation and lower enclosure of a tent. This means that users only need to purchase one main airbag, along with different functional module packages, to obtain three functions, fundamentally avoiding the redundant consumption of materials for three separate product structures and significantly reducing the user's total cost of ownership.

[0058] Solving storage redundancy, the inflatable structure achieves ultra-compact storage by utilizing the characteristics of an inflatable structure. When not in use, the main airbag and all flexible accessories (such as sealing caps, floats, and tent fabric) can be deflated and rolled into a compact package. Its storage volume is reduced by more than 70% compared to three rigid or semi-rigid products, easily stored in a corner of a car trunk, perfectly solving the storage problems of limited home storage space and unused equipment during vehicle transportation.

[0059] Addressing the pain point of ease of use: Modular connection for quick conversion, featuring a standard interface system of D-rings and attachment points. All functional modules (sealing caps, floats, windshields, tent fabric) are quickly fastened and locked to the main airbag via D-rings on the attachment points. This "plug-and-play" connection method makes switching between the three functional modes exceptionally simple and fast, typically completed by a single person within minutes, greatly improving the efficiency of outdoor activity preparation and the user experience.

[0060] The ingenuity of this invention lies not in the simple superposition of functions, but in achieving a "1+1+1 greater than 3" effect through deep structural integration and ingenious interface design. The multi-functional inclined front facade, with its 60°–75° tilt angle, is no accident. As a rooftop luggage box, it serves as an aerodynamic ramp, effectively reducing wind resistance and noise; as a small inflatable boat, it naturally becomes the bow, reducing wave-making resistance; and as a tent, it provides superior headroom and a more aesthetically pleasing design. A single structural feature simultaneously meets the core needs of three completely different scenarios, demonstrating exceptional design wisdom. Furthermore, the D-ring surrounding the upper opening is not merely a simple connection point, but constitutes a multi-functional mounting system. It is used to secure the sealing cap, tension the straps, install the float webbing, connect the tent fabric, and even suspend internal equipment. This unified interface standard is the technological foundation for achieving rapid modular switching, giving the main airbag body exceptional functional expandability.

[0061] The ingenuity of this invention lies in shifting the user's perspective from purchasing multiple products to investing in a multifunctional platform. The main airbag is no longer seen as part of a single product, but as a reliable, deformable foundational platform. Functional module packages (luggage kits, boat kits, tent kits) are "plug-ins" that can be flexibly selected according to scenario requirements. The creative result of this platform-based thinking is that it greatly simplifies the user's decision-making, purchasing, carrying, and usage processes. Users no longer need to research and purchase equipment separately for different activities; they only need to expand based on a core platform, achieving extreme simplification and maximum utilization of equipment. At the same time, the rigidity problem of inflatable luggage is solved by internally reinforced airbags, the stability and load-bearing capacity of the boat are improved by adding external floats, and the support strength of the tent is ensured by the built-in keel frame. These targeted enhancements ensure that the performance in each form reaches or approaches the level of dedicated products, breaking the stereotype that multifunctional products must compromise performance, and achieving a highly efficient unity of portability and functionality.

[0062] In summary, this invention systematically solves a series of problems associated with traditional modular outdoor gear, such as material, cost, storage, and convenience, by providing a unified, inflatable main airbag platform and combining it with a clever set of modular interfaces and functional components. Its core innovation lies in replacing fragmented functionalities with a highly integrated system design, achieving a revolutionary breakthrough of "three uses in one airbag." This provides an ideal solution for users seeking an efficient and lightweight outdoor lifestyle, possessing significant market competitiveness and promotional value.

[0063] The above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
