Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, specifically to a connecting mechanism for an inflatable tent and an inflatable tent using the connecting mechanism. Background Technology

[0002] Currently, inflatable tents are widely used in camping, disaster relief, and temporary medical services. Traditional inflatable tents are mostly one-piece designs, which have the following drawbacks:

[0003] The inflatable column and tarpaulin are difficult to assemble and disassemble quickly, damaged parts cannot be replaced independently, and the product lifespan is limited; they need to be stored as a whole during warehousing and transportation, resulting in a large volume and high logistics and storage costs.

[0004] Some tents use TPU sleeve connections, but this method suffers from numerous accessories, high consumption of production materials, and complex processes, resulting in high costs. The sleeve operation is cumbersome, severely impacting setup and takedown efficiency. Especially for heavy-duty tents (such as large camping tents and RV tents), where the tent fabric can weigh hundreds of kilograms or even more, the installation process using TPU sleeves is similar to putting on a heavy coat. It requires repeated lifting and adjusting of the heavy tent fabric relative to the inflatable column to align the sleeve and fit it onto the column. This process is extremely physically demanding, causing significant inconvenience for users with limited physical strength. The rigid sleeves disrupt the tent's aesthetic appearance and are prone to connection failure, water leakage, and stress concentration damage in extreme environments (such as strong winds and heavy rain), failing to balance reliability and ease of use, and thus unable to meet the needs of all scenarios.

[0005] Therefore, there is an urgent need for an inflatable tent connection mechanism that can achieve modular quick assembly and disassembly, standardized interfaces, reliability in extreme environments, long lifespan, and especially solve the difficulties and weight problems of heavy tent installation, while also taking into account economy and aesthetics. Utility Model Content

[0006] In view of this, the present invention provides an inflatable tent, which aims to solve the problems of inconvenient disassembly and assembly, complex production, poor reliability in extreme environments, short lifespan, and limited transportation and storage of existing inflatable tent connection methods. In particular, it addresses the problems of excessive weight and the need for repeated position adjustments during installation of heavy-duty tents. The invention provides an inflatable tent connection mechanism and inflatable tent with modular quick disassembly and assembly, standardized interface, high reliability, long lifespan, adaptability to multiple scenarios, and is especially suitable for heavy-duty and large tents.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An inflatable tent includes an inflatable column, a tent fabric, and a connecting mechanism. The connecting mechanism includes a first joint fixed to the inflatable column, a second joint fixed to the tent fabric, and a locking assembly. The locking assembly includes a first joint surface and a second joint surface that can be repeatedly engaged. The first joint surface is fixedly connected to the first joint surface, and the second joint surface is fixedly connected to the second joint surface.

[0009] By incorporating reusable physical joint surfaces and a fixed connection structure, the core components of the tent can be modularly assembled and disassembled quickly. The connection mechanism between the inflatable column and the tent fabric forms a standardized interface, significantly simplifying the manufacturing process. The physical fixation design of the first and second joints ensures structural reliability in extreme environments. The reusable nature of the locking components significantly extends product lifespan, allowing users to independently replace damaged parts. Compared to traditional integrated tents, this design reduces storage and transportation volume. This design is particularly suitable for heavy-duty tent scenarios such as large camping tents and RV tents. By eliminating the bulky TPU sleeve structure, the overall weight of the tent is significantly reduced. More importantly, the installation process eliminates the need for laborious lifting and repeated adjustments of the heavy tent fabric and inflatable column position as with traditional sleeves; connection is completed simply by joining the first and second joint surfaces, greatly saving physical exertion and significantly improving the ease of use of heavy-duty tents, especially for users with limited physical strength.

[0010] Preferably, the first mating surface and the second mating surface are mated by a zipper tooth engagement structure, a hook and loop fastening structure of a hook and loop assembly, or a mechanical fastening assembly comprising matching male and female fastening units.

[0011] The design clearly defines three engagement methods: chain tooth engagement, hook and loop fasteners, and mechanical fastening components, providing differentiated technical approaches for the product. The chain tooth engagement structure forms a linear, continuous locking interface, effectively preventing rainwater penetration along the seam; the hook and loop fastener structure provides a dynamic, area-specific connection, allowing the tarpaulin to shift moderately in strong winds to release stress. All three solutions retain the core advantage of reusable engagement, allowing users to flexibly choose based on their application scenarios: choose the chain tooth structure for high sealing requirements, and the hook and loop fastener for frequent disassembly and assembly. This design covers a full range of applications, including camping, disaster relief, and temporary medical care. The mechanical fastening component offers advantages such as vibration-resistant disengagement, quick blind operation, and strong waterproofing. The male fastener unit has elastic barbs at its end, automatically locking after insertion into the female fastener unit, requiring the release button to be pressed for separation; the fastener surface features tactile markings for quick, tactile positioning at night; and a silicone sealing ring is nested within the fastening interface, forming a rainwater drainage channel. The core value of mechanical fastening components: maintaining connection stability in high-vibration scenarios (such as vehicle transportation) while providing higher tensile strength than Velcro.

[0012] These three connection methods—zippers, Velcro, or buttons—eliminate the need for strenuous lifting and repeated adjustments of the heavy tent fabric and inflatable columns, as required by traditional sleeves. Connection is completed simply by closing the zipper along a predetermined path and aligning and pressing the fasteners or attaching the Velcro. This significantly reduces physical exertion and greatly improves the ease of use of heavy-duty tents, especially for users with limited physical strength. The key advantage of these three connection methods is that they replace the bulky and laborious TPU sleeves used in traditional heavy-duty tents. Compared to the sleeve installation method, which requires lifting and finely adjusting the heavy tent fabric, this solution's connection operations (such as pulling the zipper, attaching the Velcro, and fastening the buttons) are more linear, localized, and effortless. Users no longer need to continuously resist the weight of the entire tent fabric to adjust its position, thus greatly reducing the difficulty and physical exertion of installing heavy-duty tents.

[0013] One highly innovative approach utilizes the zipper as the core of the locking mechanism: the first mating surface on the inflatable column side and the second mating surface on the tent fabric side correspond to the male and female teeth of the zipper, directly connecting the inflatable column and the tent fabric via the zipper. This seemingly lightweight design breaks free from the constraints of traditional sleeve-type connections—eliminating the bulky sleeve not only reduces the consumption of accessories and auxiliary materials, lowering costs at the production source and allowing consumers to choose "fully functional and affordable" products; it also gives the tent smooth lines and a clear outline, showcasing a modern design aesthetic of "simple yet elegant"; simultaneously, it removes the constraints of the sleeve on operation, making setup and takedown easier and faster. This zipper-centric connection innovation not only continues the fundamental advantages of connection mechanisms—"standardized interfaces, high reliability, and long lifespan"—but also achieves multi-dimensional breakthroughs in economy, aesthetics, and ease of use, becoming a highly representative practical solution under the connection mechanism concept.

[0014] The solution, using hook-and-loop fasteners (Velcro) as the core of the connection, also showcases unique innovative value: the first joint surface on the side of the inflatable column features a hook-like structure, while the second joint surface on the side of the tent fabric matches a layer of plush fibers. The mechanical interlocking between the hooks and loops enables a quick connection between the inflatable column and the tent fabric. This seemingly simple design has revolutionized traditional sleeve connections—by eliminating complex sleeves, it significantly reduces the use of additional accessories and sewing materials, compressing material costs and manufacturing complexity from the production end, allowing consumers to obtain a well-balanced tent product at a more affordable price. Furthermore, thanks to the flexible fit of the hook-and-loop fasteners, which are "without hard edges or protrusions," the tent seams present a natural and smooth wrapping feel, weakening the industrial feel of mechanical connections and conveying a "soft and integrated" design aesthetic. At the same time, it breaks the limitations of sleeves on operating speed, allowing connection to be completed simply by hand pulling. Even at night or in inclement weather, the connection and separation can be completed quickly by touch, significantly improving operational efficiency in emergency scenarios (such as disaster relief and medical tent setup). This hook-and-hair-based connection solution inherits the fundamental characteristics of connection mechanisms, namely "standardized interfaces, repeatable connections, and reliability in extreme environments." It also opens up new dimensions in terms of stress adaptability (allowing slight displacement of the tent fabric to release load under strong winds), ease of blind operation, and universal applicability across all scenarios (from camping and leisure to professional disaster relief). It has become a benchmark choice for high-frequency dynamic scenarios under the concept of connection mechanisms.

[0015] Preferably, the first joint is a flexible carrier sheet, which has a continuous curved surface structure that matches the contour of the outer wall of the inflatable column.

[0016] The continuous curved surface structure of the flexible carrier sheet perfectly adapts to the deformation characteristics of the inflatable column. When the inflation pressure changes, the curved carrier maintains full-area contact with the column surface through elastic deformation, eliminating the local stress concentration problem caused by traditional planar connectors. This structure simultaneously achieves triple optimization: curved surface curvature matching reduces wind resistance and turbulence; flexible materials absorb vibration energy; and the continuous contact surface evenly distributes the load.

[0017] Preferably, the first joint is a fabric layer provided on the outer surface of the inflatable column, and the first joint surface is sewn and fixed to the fabric layer. The second joint is a fabric layer provided on the outer surface of the tarpaulin, and the second joint surface is sewn and fixed to the fabric layer.

[0018] The combination of fabric layers and sewn-on fastening creates revolutionary production advantages. The fabric layer is applied directly to the surface of the inflatable column, eliminating the traditional cutting process for connecting fabric; the sewn-on fastening process is compatible with existing sewing production line equipment, requiring no specialized welding machinery. This design improves tent manufacturing efficiency, and the fabric layer can be made from recycled materials for environmentally friendly production. More importantly, the sewn structure forms a mechanically interlocking interface with peel strength far exceeding that of adhesive bonding, maintaining connection stability in high-temperature and high-humidity environments. Users only need to remove the seams and replace parts during maintenance, significantly reducing maintenance costs.

[0019] Preferably, the first joint is a heat-fused bonding layer formed on the surface of the inflatable column, and the first joint surface is bonded to the heat-fused bonding layer through a heat-fused interface. The second joint is a heat-fused bonding layer formed on the surface of the tarpaulin, and the second joint surface is bonded to the heat-fused bonding layer through a heat-fused interface.

[0020] The combination of a hot-melt bonding layer and a hot-melt interface solves a decade-old problem in the inflatable products industry. Traditional adhesives are prone to fatigue and delamination under repeated deformation of the inflatable column, while the hot-melt interface forms a molecular-level interpenetration and fusion, with its bonding strength increasing with each use. This technology completely eliminates organic solvent pollution from adhesive processes, complying with EU REACH environmental standards. The hot-melt bonding layer also acts as a reinforcing rib of the inflatable column, improving local puncture resistance. After thousands of inflation and deflation tests, the connection interface showed no performance degradation, pioneering a permanent connection for inflatable tents.

[0021] Preferably, the hot-melt interface comprises a molten interpenetration layer of inflatable column material or tarpaulin material and hook surface substrate.

[0022] The microstructure design of the molten interpenetrating layer achieves synergistic enhancement of material properties. The inflatable column material and the hook-face substrate form an interpenetrating composite interface in the molten state, retaining the flexibility of the substrate while achieving alloy-like interfacial strength. This structure effectively blocks ultraviolet radiation from penetrating deep into the bonding interface, addressing a critical issue of aging and failure in outdoor products. Unlike the brittle bonding zones of traditional welds, the interpenetrating layer possesses energy dissipation characteristics, absorbing energy through microcrack propagation under impact loads, preventing overall fracture. This design results in a breakthrough extension of tent lifespan.

[0023] Preferably, the connecting mechanism is a sewn structure: the edge of the tarpaulin is directly fixed to the outer surface of the inflatable column by stitching, forming an integral connection that cannot be disassembled.

[0024] This solution completely eliminates the joints and locking components, achieving three core advantages:

[0025] 1. Minimal production cost reduction: Eliminate all connecting accessories, reduce the consumption of cut pieces and auxiliary materials, and reduce the production process to a single sewing operation;

[0026] 2. Lightweight Breakthrough: The absence of additional connectors reduces the overall weight of the tent;

[0027] 3. Enhanced reliability: The stitches form a continuous stress-dispersing interface, eliminating the risk of connectors falling off.

[0028] A tent connection structure includes an inflatable column connection part, a tent fabric connection part, and a re-lockable coupling member, wherein the coupling member includes a zipper assembly with engaging teeth or a hook and loop assembly with a hook and loop interface; a first part of the coupling member is fixed to the inflatable column connection part, and a second part is fixed to the tent fabric connection part.

[0029] Modular joint component design revolutionizes traditional tent manufacturing. Zipper and hook-and-loop components form a standardized connection system, allowing for separate production and reassembly of the inflatable columns and tent fabric, significantly reducing defect rates. The joint components achieve mechanical interlocking through fixing to the connecting parts, and their repeatable locking feature supports user-upgraded accessories. This structure also pioneers a new business model for tent rentals: rental companies provide the basic column frame, and users rent different functional tent fabrics as needed. This structure is particularly significant for heavy-duty tents: standardized interfaces and easy assembly (zippers, Velcro, fasteners) effectively solve the pain point of repeatedly adjusting the heavy tent fabric position when installing traditional TPU sleeves on heavy-duty tents.

[0030] Preferably, the inflatable column connecting part includes a carrier belt, and the inflatable column contact surface of the carrier belt is a concave curved surface with the curvature of the outer wall of the column.

[0031] The concave curved surface design of the carrier belt achieves a dual breakthrough in fluid dynamics optimization and structural reinforcement. The concave curved surface forms an aerodynamic continuity with the outer wall of the column, significantly reducing wind noise and drag coefficient. Simultaneously, the curved structure enhances the bending stiffness of the carrier belt, preventing structural collapse under snow loads. More importantly, the concave curved surface increases the contact area with the column, resulting in more even load distribution and preventing material creep caused by localized stress. This design improves the tent's wind resistance rating by two levels and eliminates abnormal noise in strong winds.

[0032] Preferably, the hook and loop interface includes hook elements and a rough substrate, wherein the hook elements form a discontinuous pattern on the base tape.

[0033] The discontinuous pattern distribution achieves a quantum leap in hook and loop fastener performance. Discretely distributed hook surface elements create microscopic stress interruption points, preventing cracks from propagating along the baseband direction; the inter-element gaps allow the baseband to expand and contract freely, perfectly adapting to changes in the diameter of the inflatable column; the patterned arrangement further optimizes hook and loop dynamics, achieving revolutionary performance of "easy to tear but difficult to detach"—the vertical peel force is only one-third that of planar hook and loop fasteners, while the shear strength is doubled. Users can quickly remove the tarpaulin with one hand, yet the connection remains secure even in gale-force winds.

[0034] Preferably, the inflatable column connecting part is a first chain sewn onto the inflatable column, and the tarpaulin connecting part is a second chain sewn onto the tarpaulin.

[0035] The sewn-on chain strap structure pioneers a minimalist design paradigm. Eliminating all intermediate connectors reduces the tent's weight to half that of traditional products; the stitching forms a mechanical overload protection mechanism, gradually breaking to absorb energy when wind speeds exceed design thresholds, preventing tearing of the poles or tent fabric. This design also significantly reduces production complexity: the direct-sewn chain straps drastically reduce the number of parts and assembly time. In disaster relief scenarios, this tent sets a new industry record for deployment speed.

[0036] The advantages of this utility model compared to the prior art are:

[0037] Modular quick assembly and disassembly: The reusable locking mechanism allows for quick assembly and disassembly of the inflatable column and tarpaulin, enabling users to independently replace damaged parts and significantly extending product lifespan; setup / packing efficiency is greatly improved, making operations more efficient in emergency scenarios (such as disaster relief and medical tent setup).

[0038] Standardized interfaces and simplified production: The connecting mechanism forms a standardized interface, replacing the traditional complex connection method (such as sleeve), reducing the consumption of accessories and auxiliary materials, reducing costs and simplifying processes from the production end, which is conducive to large-scale production and product accessibility.

[0039] Extreme environment reliability: The physical fixing design of the first and second joints, combined with the joint strength of the locking components, ensures stable connection under extreme environments such as strong winds and heavy rain, preventing structural failure; the zipper teeth mesh to form a linear and continuous locking interface, effectively blocking water and preventing seepage; the hook and loop components allow for slight displacement of the tarpaulin to release stress, avoiding stress concentration damage.

[0040] Warehousing and transportation optimization: The modular design allows the inflatable column and tarpaulin to be separated and stored, significantly reducing the volume of warehousing and transportation and saving logistics and storage costs.

[0041] Multi-scenario adaptation: It offers two technical options: zipper (high sealing performance, suitable for scenarios such as camping in heavy rain and temporary medical care) and hook and loop (easy to install and remove + stress relief, suitable for high-frequency dynamic scenarios such as camping in strong winds and disaster relief and resettlement), covering the needs of all scenarios, and users can choose according to their needs.

[0042] Breakthrough in the applicability of heavy-duty tents:

[0043] Significant weight reduction: Abandoning the traditional bulky TPU sleeve structure, the overall weight of heavy-duty tents is directly reduced, improving portability.

[0044] Revolutionary simplified installation: Zipper, Velcro, or mechanical fastener connections completely eliminate the tedious steps of repeatedly lifting and adjusting the heavy tent fabric when installing heavy tents using traditional TPU sleeves. Users only need to perform relatively light operations (such as pulling the zipper, attaching the Velcro, and fastening the fasteners) to complete the connection, greatly saving physical exertion and especially solving the pain point of users with limited physical strength when installing heavy tents.

[0045] Enhanced user experience: Makes the setup of heavy-duty products such as large camping tents and RV tents easier and more convenient, significantly improving user experience and satisfaction. Attached Figure Description

[0060] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0061] As attached Figure 1-3This embodiment provides an inflatable tent, including an inflatable column 1, a tent fabric 2, and a connecting mechanism 3. The connecting mechanism 3 includes a first joint 31 fixed to the inflatable column 1, a second joint 32 fixed to the tent fabric 2, and a locking assembly 33. The locking assembly 33 includes a first joint surface 331 and a second joint surface 332 that can be repeatedly joined. The first joint surface 331 is fixedly connected to the first joint 31, and the second joint surface 332 is fixedly connected to the second joint 32.

[0062] By incorporating reusable physical joint surfaces and a fixed connection structure, the core components of the tent can be modularly assembled and disassembled quickly. The connection mechanism 3 between the inflatable column 1 and the tent fabric 2 forms a standardized interface, significantly simplifying the manufacturing process. The physical fixing design of the first joint 31 and the second joint 32 ensures structural reliability in extreme environments. The reusable locking component 33 significantly extends product lifespan, allowing users to independently replace damaged parts. Compared to traditional integrated tents, this design reduces storage and transportation volume.

[0063] In this embodiment, the first mating surface 331 and the second mating surface 332 are mated by the zipper unit's tooth meshing structure 333.

[0064] The 333 chain tooth meshing structure forms a linear and continuous locking interface, effectively preventing rainwater from seeping in along the joint. It has the core advantage of being able to be repeatedly joined. The chain tooth structure is chosen for high sealing requirements. This design covers all application scenarios such as camping, disaster relief, and temporary medical care.

[0065] Using a zipper as the core carrier of the locking component 33 is a highly innovative practice: the first joint surface 331 on the side of the inflatable column 1 and the second joint surface 332 on the side of the tent fabric 2 correspond to the male and female teeth of the zipper, respectively, directly connecting the inflatable column 1 and the tent fabric 2 through the zipper. This design, seemingly lightweight, breaks through the constraints of traditional sleeve-type connections—by abandoning the bulky sleeve, it not only reduces the consumption of accessories and auxiliary materials, but also reduces costs from the source of production, giving consumers the opportunity to choose products that are "fully functional and affordable"; it also gives the tent smooth lines and a clear outline, showcasing a modern design aesthetic of "simple yet elegant"; at the same time, it removes the constraints of the sleeve on operation, making setup and storage easier and faster. This zipper-centric connection innovation not only continues the underlying advantages of the connection mechanism 3—"standardized interface, high reliability, and long lifespan"—but also achieves multi-dimensional breakthroughs in economy, aesthetics, and ease of use, becoming a highly representative practical solution under the concept of connection mechanism 3. This solution is particularly suitable for heavy-duty scenarios such as large camping tents and RV tents. Compared to traditional heavy-duty tents where the TPU sleeves and heavy tent fabric need to be adjusted manually during installation, this solution only requires pulling the zipper along the inflatable column to complete the connection. The operation does not require fine-tuning against the overall weight of the tent fabric, significantly saving physical effort.

[0066] In this embodiment, the first joint 31 and the second joint 32 are flexible carrier sheets, which have a continuous curved surface structure that matches the outer contour of the inflatable column 1 or the tarpaulin 2.

[0067] The continuous curved surface structure of the flexible carrier sheet perfectly adapts to the deformation characteristics of the inflatable column 1 and the tarpaulin 2. When the inflation pressure changes, the curved carrier maintains full-area contact with the column surface through elastic deformation, eliminating the local stress concentration problem caused by traditional planar connectors. This structure simultaneously achieves triple optimization: curved surface curvature matching reduces wind resistance and turbulence; flexible materials absorb vibration energy; and the continuous contact surface evenly distributes the load. Example 2

[0068] As attached Figure 4 This embodiment provides an inflatable tent, including an inflatable column 1, a tent fabric 2, and a connecting mechanism 3. The connecting mechanism 3 includes a first joint portion 31 fixed to the inflatable column 1, a second joint portion 32 fixed to the tent fabric 2, and a locking assembly 33. The locking assembly 33 includes a first joint surface 331 and a second joint surface 332 that can be repeatedly joined. The first joint surface 331 is fixedly connected to the first joint portion 31, and the second joint surface 332 is fixedly connected to the second joint portion 32. The first joint surface 331 and the second joint surface 332 are joined by a zipper unit's tooth engagement structure 333.

[0069] In this embodiment, the first joint 31 is a fabric layer provided on the outer surface of the inflatable column 1, and the first joint surface 331 is sewn and fixed to the fabric layer.

[0070] The combination of fabric layer and sewn fastening creates revolutionary production advantages. The fabric layer is applied directly to the surface of the inflatable column 1, eliminating the traditional cutting process for connecting fabric; the sewn fastening process is compatible with existing sewing production line equipment, requiring no specialized welding machinery. This design improves tent manufacturing efficiency, and the fabric layer can be made from recycled materials for environmentally friendly production. More importantly, the sewn structure forms a mechanically interlocking interface with a peel strength far exceeding that of adhesive bonding, maintaining connection stability in high-temperature and high-humidity environments. Users only need to remove the seams and replace parts during maintenance, significantly reducing maintenance costs. Example 3

[0071] This embodiment provides an inflatable tent, including an inflatable column, a tent fabric, and a connecting mechanism. The connecting mechanism includes a first joint portion fixed to the inflatable column, a second joint portion fixed to the tent fabric, and a locking assembly. The locking assembly includes a first joint surface and a second joint surface that can be repeatedly engaged. The first joint surface is fixedly connected to the first joint portion, and the second joint surface is fixedly connected to the second joint portion. The engagement method between the first joint surface and the second joint surface is a zipper unit tooth engagement structure.

[0072] The first joint is a fabric layer on the outer surface of the inflatable column or a heat-fused bonding layer formed on the surface of the inflatable column. The first joint surface is sewn and fixed to the fabric layer or bonded to the heat-fused bonding layer through a heat-fused interface. The second joint is a fabric layer on the outer surface of the tarpaulin or a heat-fused bonding layer formed on the surface of the tarpaulin. The second joint surface is sewn and fixed to the fabric layer or bonded to the heat-fused bonding layer through a heat-fused interface. The heat-fused interface includes a molten interpenetrating layer between the inflatable column material and the hook surface substrate.

[0073] The combination of a hot-melt bonding layer and a hot-melt interface solves a decade-old problem in the inflatable products industry. Traditional adhesives are prone to fatigue and delamination under repeated deformation of the inflatable column, while the hot-melt interface forms a molecular-level interpenetration and fusion, with its bonding strength increasing with each use. This technology completely eliminates organic solvent pollution from adhesive processes, complying with EU REACH environmental standards. The hot-melt bonding layer also acts as a reinforcing rib of the inflatable column, improving local puncture resistance. After thousands of inflation and deflation tests, the connection interface showed no performance degradation, pioneering a permanent connection for inflatable tents.

[0074] The microstructure design of the molten interpenetrating layer achieves synergistic enhancement of material properties. The inflatable column material and the hook-face substrate form an interpenetrating composite interface in the molten state, retaining the flexibility of the substrate while achieving alloy-like interfacial strength. This structure effectively blocks ultraviolet radiation from penetrating deep into the bonding interface, addressing a critical issue of aging and failure in outdoor products. Unlike the brittle bonding zones of traditional welds, the interpenetrating layer possesses energy dissipation characteristics, absorbing energy through microcrack propagation under impact loads, preventing overall fracture. This design results in a breakthrough extension of tent lifespan. Example 4

[0075] As attached Figure 5 This embodiment provides an inflatable tent, including an inflatable column 1, a tent fabric 2, and a connecting mechanism 3. The connecting mechanism 3 includes a first joint portion 31 fixed to the inflatable column 1, a second joint portion 32 fixed to the tent fabric 2, and a locking assembly 33. The locking assembly 33 includes a first joint surface 331 and a second joint surface 332 that can be repeatedly joined. The first joint surface 331 is fixedly connected to the first joint portion 31, and the second joint surface 332 is fixedly connected to the second joint portion 32. The first joint surface 331 and the second joint surface 332 are joined by a hook and loop fastener structure 334 of the hook and loop assembly.

[0076] The hook and loop fastener structure provides a dynamic, area-specific connection, allowing the tarpaulin 2 to shift moderately in strong winds to release stress. It features the core advantage of being reusable and is ideal for scenarios requiring frequent disassembly and reassembly, covering a wide range of applications including camping, disaster relief, and temporary medical services.

[0077] The solution, which uses hook and loop fasteners (Velcro) as the core of the locking mechanism, also showcases unique innovative value: the first joint surface 331 on the side of the inflatable column 1 features a hook-like structure, while the second joint surface 332 on the side of the tent fabric 2 is matched with a plush fiber layer. The mechanical interlocking between the hooks and loops enables a quick connection between the inflatable column 1 and the tent fabric 2. This seemingly simple design has revolutionized traditional sleeve connections—by eliminating complex sleeves, it significantly reduces the use of additional accessories and sewing materials, compressing material costs and manufacturing complexity from the production end, allowing consumers to obtain a well-balanced tent product at a more affordable price. Furthermore, thanks to the flexible fit of the hook and loop fasteners, which are "without hard edges or protrusions," the tent seams present a natural and smooth wrapping feel, weakening the industrial feel of mechanical connections and conveying a "soft and integrated" design aesthetic. At the same time, it breaks the limitations of sleeves on operating speed, allowing for assembly and disassembly with only a tearing motion by hand. Even at night or in inclement weather, it allows for quick connection or separation via touch, significantly improving operational efficiency in emergency scenarios (such as disaster relief and medical tent setup). This hook-and-loop connection solution inherits the fundamental characteristics of Connection Mechanism 3—standardized interface, repeatable connection, and reliability in extreme environments—while also opening up new dimensions in stress adaptability (allowing slight displacement of the tent fabric 2 to release load under strong winds), ease of blind operation, and universal applicability across all scenarios (from camping and leisure to professional disaster relief). It has become a benchmark choice for adapting to high-frequency dynamic scenarios under the Connection Mechanism 3 concept. This solution has significant advantages in heavy-duty tents (such as large RV tents). During installation, simply position the tent fabric roughly and attach the Velcro to complete the connection, completely avoiding the enormous physical exertion required for precise insertion and repeated adjustments when installing heavy-duty tents with traditional TPU sleeves. The operation is extremely convenient and labor-saving, making it particularly suitable for situations requiring frequent disassembly and assembly or for users with limited physical strength.

[0078] Similar to embodiments 1-3, the first joint 31 and the second joint 32 in this embodiment can be independent components, as shown in the attached figure. Figure 5 It can also be the inflatable column 1 and the tarpaulin 2 themselves, as shown in the attached document. Figure 6 Specifically, the first joint 31 and the second joint 32 can be a flexible carrier sheet, a fabric layer disposed on the outer surface of the inflatable column 1 or the tarpaulin 2, or a heat-fused bonding layer formed on the surface of the inflatable column 1 or the tarpaulin 2. The first joint surface 331 and the second joint surface 332 are bonded to the heat-fused bonding layer through a heat-fused interface. Example 5

[0079] As attached Figure 7This embodiment provides a tent connection structure, including an inflatable column connection portion 41, a tent fabric connection portion 42, and a re-lockable coupling member 43. The coupling member 43 includes a zipper assembly 431 with engaging teeth. A first portion 432 of the coupling member 43 is fixed to the inflatable column connection portion 41, and a second portion 433 is fixed to the tent fabric connection portion 42. In other embodiments, the zipper assembly with engaging teeth can be replaced with a hook and loop assembly with a hook and loop interface.

[0080] The modular joining component 43 revolutionizes traditional tent manufacturing. The zipper assembly 431 and hook and loop assembly form a standardized connection system, allowing the inflatable columns and tent fabric to be manufactured separately and then reassembled, significantly reducing defect rates. The joining component 43 achieves mechanical interlocking through fixing to the connecting parts, and its repeatable locking feature allows users to upgrade accessories independently. This structure also pioneers a new business model for tent rentals: rental companies provide the basic column frame, and users rent different functional tent fabrics as needed. This simple and reliable connection structure is particularly beneficial for reducing the weight of heavy-duty tents and simplifying their installation process.

[0081] In this embodiment, the inflatable column connecting part 41 includes a carrier belt 411, and the inflatable column contact surface of the carrier belt 411 is a concave curved surface that matches the curvature of the outer wall of the column.

[0082] The 411 concave surface design of the carrier belt achieves a dual breakthrough in fluid dynamics optimization and structural reinforcement. The concave surface forms an aerodynamic continuity with the outer wall of the column, significantly reducing wind noise and drag coefficient. Simultaneously, the curved structure enhances the bending stiffness of the 411 carrier belt, preventing structural collapse under snow loads. More importantly, the concave surface increases the contact area with the column, resulting in more even load distribution and preventing material creep caused by localized stress. This design improves the tent's wind resistance rating by two levels and eliminates abnormal noise in strong winds.

[0083] In this embodiment, the hook and loop interface includes hook elements and a rough substrate, with the hook elements forming a discontinuous distribution pattern on the base tape.

[0084] The discontinuous pattern distribution achieves a quantum leap in hook and loop fastener performance. Discretely distributed hook surface elements create microscopic stress interruption points, preventing cracks from propagating along the baseband direction; the inter-element gaps allow the baseband to expand and contract freely, perfectly adapting to changes in the diameter of the inflatable column; the patterned arrangement further optimizes hook and loop dynamics, achieving revolutionary performance of "easy to tear but difficult to detach"—the vertical peel force is only one-third that of planar hook and loop fasteners, while the shear strength is doubled. Users can quickly remove the tarpaulin with one hand, yet the connection remains secure even in gale-force winds. Example 6

[0085] As attached Figure 8This embodiment provides a tent connection structure, including a first chain strap 51 sewn to an inflatable column, a second chain strap 52 sewn to a tent fabric, and a zipper assembly 53 with engaging teeth. In other embodiments, the zipper assembly with engaging teeth can be replaced with a hook and loop assembly with a hook and loop interface.

[0086] The sewn-on chain conveyor system pioneers a minimalist design paradigm. Eliminating all intermediate connectors reduces the tent's weight to half that of traditional products; the stitching forms a mechanical overload protection mechanism, gradually breaking to absorb energy when wind speeds exceed design thresholds, preventing tearing of the poles or tent fabric. This design also significantly reduces production complexity: the direct-sewn chain conveyor system drastically reduces the number of parts and assembly time. In disaster relief scenarios, this tent sets a new industry record for deployment speed. The simple and reliable connection structure is particularly beneficial for reducing the weight of heavy-duty tents and simplifying their installation process. Example 7

[0087] This embodiment provides a low-cost inflatable tent whose connecting mechanism adopts a direct sewing method: the edge of the tent fabric is sewn to the outer surface of the inflatable column using high-strength stitching, forming a permanent integrated connection. This solution completely eliminates the need for joints and locking components, achieving three core advantages:

[0088] 1. Minimal production cost reduction: Eliminate all connecting accessories, reduce the consumption of cut pieces and auxiliary materials, and reduce the production process to a single sewing operation;

[0089] 2. Lightweight Breakthrough: The absence of additional connectors reduces the overall weight of the tent;

[0090] 3. Enhanced reliability: The stitches form a continuous stress-dispersing interface, eliminating the risk of connectors falling off. Example 8

[0091] In this embodiment, the locking assembly adopts a mechanical fastening structure:

[0092] - The male snap unit (such as a mushroom-head snap or a pin snap) is fixed to the first mating surface.

[0093] - The female fastener unit (such as a fastener ring or a retaining slot) is fixed to the second mating surface.

[0094] Key points of innovative design:

[0095] 1. Vibration-resistant tripping: The male buckle unit is equipped with an elastic barb at the end, which automatically locks after being inserted into the female buckle unit. It can only be separated by pressing the release button.

[0096] 2. Quick blind operation: The buckle surface is equipped with raised tactile markings, allowing for quick positioning and fastening by hand at night;

[0097] 3. Enhanced waterproofing: The interlocking interface features a nested silicone sealing ring, forming a channel for rainwater diversion.

[0098] Core value: Maintains connection stability under high vibration conditions, such as in vehicle transportation, while providing higher tensile strength than Velcro. For heavy-duty tents, mechanical fastening offers a choice between the strength of zippers and the convenience of Velcro, and its "align-press" fastening method is more effortless and direct than traditional sleeve installation.
