[0002] In existing technologies, devices that provide heating functions for flexible substrates such as tents and clothing, such as directly integrated or simply fixed heating elements, often have some inherent limitations. On the one hand, the way these heating devices are integrated with the substrate is often relatively fixed, making disassembly difficult and hindering the flexible adjustment or removal of the heating function according to actual needs (such as temperature changes, cleaning, and maintenance), thus making modular applications difficult. On the other hand, if insulation is included, existing insulation structures (such as insulation layers using certain inorganic materials) may result in a bulky and heavy overall device, affecting the product's portability and storage. Therefore, existing technologies are still insufficient in providing a flexible system that is structurally sound, easy to assemble and disassemble, lightweight, and can flexibly combine heating and insulation functions, making it difficult to fully meet the needs of diverse application scenarios.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0038] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] Example 1: Demountable Modular Flexible Heating System

[0041] This embodiment describes the basic structure of a detachable modular flexible heating system, which can be widely used in flexible substrates such as tents, clothing, sleeping bags, and floor mats. (Refer to...) Figures 1 to 3 The system mainly includes at least one flexible heating component 10, at least one flexible inflatable heat insulation component 20, and a detachable fixing mechanism 30.

[0042] In this embodiment, the flexible heating component 10 presents a sophisticated multilayer composite structure designed to achieve excellent performance and durability. From the inner side facing the space to be heated to the outer side near the flexible substrate, the following components can be stacked sequentially:

[0043] Inner contact layer 11: As the layer directly facing the user, its material selection must consider both functionality and scenario adaptability. For example, the following materials can be used:

[0044] Antistatic silicone-coated fiberglass cloth: It has good skin-friendliness and disinfection resistance, and is especially suitable for medical or hygiene-required scenarios.

[0045] PU coated fiberglass cloth: It has good economy, water resistance and dirt resistance, and is suitable for general outdoor or daily use.

[0046] Coated aramid fireproof cloth: It is lightweight, low density, low thermal conductivity and excellent low temperature resistance, suitable for extremely cold environments or occasions with strict weight requirements.

[0047] Other optional materials include: PTFE-coated fiberglass cloth, aerogel composite fabric, stainless steel fiber cloth, coated ceramic fiber cloth, basalt-coated fiber cloth, etc., to meet specific requirements for wear resistance, fire resistance, insulation, or strength. Selecting appropriate inner contact layer materials not only improves the user experience but also enhances the product's suitability and durability in specific environments.

[0048] The first shielding layer 12a is disposed between the inner contact layer 11 and the heating layer 13, and is preferably made of conductive fiber cloth (such as carbon fiber cloth), mesh conductor (such as copper woven shielding mesh), or film conductor (such as conductive coating film), and is reliably grounded. This shielding layer, as a grounding protection layer, can effectively shield electromagnetic interference and provide electrical safety protection in case of accidents.

[0049] Heating layer 13: This is the core component for achieving the heating function. It can be made of at least one material selected from novel semiconductor heating materials, polymer heating materials, PTC heating materials, and graphene heating materials. These materials typically possess good flexibility, heating uniformity, and efficiency. Choosing these advanced heating materials helps achieve uniform, efficient, and flexible heating results.

[0050] The heating layer 13 and its associated circuitry (such as electrode connection points) are tightly sealed with an insulating encapsulation material. In a preferred embodiment, this encapsulation material is a waterproof film material with elasticity and stretchability. For example, a multi-layer composite structure can be used, such as an outer polyurethane (PU) film + a middle elastic mesh (such as nylon or spandex fiber mesh) + an inner polyester (PET) film, manufactured through a thermoforming process. This special encapsulation material endows the flexible heating assembly 10 with excellent properties:

[0051] High elasticity and stretchability: It can adapt to repeated bending and stretching of flexible substrates without being easily damaged, thus ensuring the integrity of the heating layer and internal circuitry.

[0052] Excellent water resistance: It can achieve a high water resistance rating (e.g., IP67 or higher), effectively preventing the intrusion of water and sweat, improving the durability of the product, and enabling it to adapt to humid environments and even support limited washing (specific requirements depend on the overall design and connector rating), which helps to solve the problem of poor water resistance in existing technologies.

[0053] Reliable insulation: ensures electrical safety.

[0054] Reflective layer 14: Located on the side of the heating layer 13 closest to the flexible substrate. Its material can be selected from: aluminum foil (or aluminum reflective film), aluminized polyester film (PET aluminized film), ceramic coating materials with infrared reflective function, or aerogel composite materials, etc. The presence of reflective layer 14 significantly improves the thermal efficiency of the heating system, as it reflects most of the heat radiated outward from the heating layer back to the space to be heated, reducing heat loss towards the substrate.

[0055] The second shielding layer 12b is located on the outermost side, facing the flexible substrate or the stacked flexible inflatable thermal insulation assembly 20. Its material and function are similar to the first shielding layer 12a, also serving as a grounding protection layer, further enhancing electrical safety. The double-shielding design provides more comprehensive safety protection.

[0056] Interlayer fixing and edge treatment of flexible heating component 10:

[0057] The aforementioned material layers (except for the heating layer itself, which is typically a monolithic film or fabric) can be fixed and assembled by sewing (in non-heating areas) or using environmentally friendly adhesives (such as silicone). The outer edges of the assembly require meticulous finishing, such as sewing, and a portion of a detachable fixing mechanism 30 (e.g., hook or loop fastener, anchoring holes) can be added at these points. To prevent issues like fiber leakage and wear at the edges (especially after cutting the fabric layer), heat sealing, sealant application, ultrasonic welding, or edge binding can be used. Edge binding may involve folding the fabric edges inwards and sewing or heat sealing to create a neat and secure finish. These meticulous manufacturing processes ensure the integrity and durability of the heating assembly.

[0058] To ensure safe, reliable, and convenient electrical connections, the flexible heating assembly 10 can integrate the following structure:

[0059] Electrode wiring structure: The electrode leads of heating layer 13 are connected to wires via welding or crimping. The wires are protected by an insulating sheath (such as silicone rubber or PVC). The ends of the wires connect to a waterproof, pluggable connector (e.g., an aviation plug with IP67 or IP68 protection rating, whose shell can be nylon or metal, and has a built-in sealing ring). This design ensures a secure and reliable connection to an external power supply or controller (not shown), while also providing good waterproof and moisture-proof performance and facilitating user plugging and unplugging.

[0060] Overheat protection device: In this embodiment, an overheat protection device, such as a thermistor, normally closed temperature switch, or thermal fuse, is installed in series or in parallel (depending on the type of protection device) in the electrode circuit of the heating layer 13 (usually near the power input point). This device can be connected by soldering, conductive adhesive bonding, or flexible printed circuit board (FPC) lamination, and is tightly bonded to the substrate (such as PET or PI film) of the heating layer 13 using a thermally conductive insulating adhesive layer (such as silicone or epoxy resin). This tight-fitting installation method ensures that the overheat protection device can accurately and quickly sense the actual temperature of the heating layer, promptly cutting off the power supply or issuing an alarm when the temperature rises abnormally, achieving a self-protection power-off function and greatly improving safety.

[0061] Temperature sensor: A temperature sensor (such as an NTC thermistor, PT100, etc.) can be installed on or near the surface of the heating layer 13. Its signal line is also led out to a connector or separately for connecting to an external temperature control device (not shown). The setting of the temperature sensor allows for real-time monitoring and precise control of the heating temperature, meeting the temperature requirements of different scenarios and further improving safety.

[0062] Reference Figures 1 to 3 The flexible inflatable thermal insulation component 20 is an important part of this invention, providing lightweight and efficient thermal insulation capabilities. Its main body is composed of a flexible membrane material, preferably an environmentally friendly material with good airtightness, high strength, good toughness, and wear resistance, such as PVC, TPU, or silicone. The membrane material itself may be a single-layer or multi-layer composite structure to enhance performance.

[0063] The internal structure is a honeycomb-like air cell structure 21, specifically, by using processes such as hot pressing with a mold or high-frequency welding to separate two layers of membrane material into a large number of independent or partially interconnected small honeycomb-like air cells. After inflation, this structure effectively divides the internal air, greatly suppressing heat transfer caused by air convection and providing excellent thermal insulation performance. At the same time, the honeycomb structure itself has good planar support and structural stability. The design of the honeycomb walls or the treatment within the honeycomb cavities can be further optimized to enhance thermal insulation or stability.

[0064] In another possible implementation, high-strength fiber threads (such as nylon filaments) are connected to the upper and lower substrates at regular intervals within the honeycomb air column cavity through processes such as molding or ultrasonic welding to form a "filament-drawing" support structure.

[0065] Edge sealing and valves: The edges of the components are reliably sealed using high-frequency heat sealing or adhesive bonding to ensure airtightness. At least one inflation / deflation valve is provided, preferably a type with excellent sealing performance and easy operation (such as a check valve or self-sealing valve). As a preferred option, to enhance safety, a safety relief valve (a spring-loaded or pressure-sensing safety valve) can be added to the component. This valve automatically releases some gas when the internal pressure unexpectedly exceeds a preset safety value, preventing overcharging damage.

[0066] This inflatable flexible thermal insulation component 20, compared to traditional solid thermal insulation materials, is primarily composed of air and is extremely lightweight. Its volume is significantly reduced after deflation, making it very easy to fold and store. It utilizes air as the insulation medium and suppresses convection through its internal structure (honeycomb or brushed) to achieve excellent thermal insulation. The thickness and support force can be adjusted by varying the degree of inflation.

[0067] The detachable fixing mechanism 30 is key to achieving system modularity and convenient assembly / disassembly. It can be a combination of one or more of the following, disposed on the edge or surface of the flexible heating component 10 and / or the flexible inflatable insulation component 20, and mate with corresponding structures on the flexible substrate:

[0068] Velcro 31 Fixing: Combination Figure 4 The components have either hooked or textured surfaces, while the substrate has a corresponding textured or hooked surface. For example, the outer side of the heating component is hooked, and the inner wall of the tent is textured. If used in combination, the side of the insulation component facing the tent has hooks, the side facing the heating component has textured surfaces, and the side of the heating component facing the insulation component has hooks. This method is quick and easy to install and is suitable for large-area installation.

[0069] Anchor hole 32 is fixed to rope 33 and hook 34 at the end of rope: combination Figure 6 Reinforced anchoring holes 32 (such as metal pores or fabric reinforcing rings) are provided at the edge of the component, and it is then attached to the hanging points, webbing loops, or frame on the base material using ropes 33, elastic cords, or hooks 34. This method provides a secure fixation and is suitable for applications requiring the resistance to a certain amount of tension.

[0070] Guide channels and support strips / cables, along with fasteners: Guide channels are formed at the edge of the component by sewing or heat sealing. Flexible support strips (such as fiberglass rods) or thin steel cables are threaded into the channels, and then fasteners (such as tensioners or hooks) are used to secure both ends of the support strips or cables to the frame of the flexible substrate or pre-set fixing points. The manufacturing process of the guide channels and the insertion and fixing methods of the steel cables must ensure functionality and durability. This method keeps the component flat and is suitable for applications requiring taut installation.

[0071] Snap fastener 35 for fixation: (Connection) Figure 5Snap fasteners (male and female) are installed at corresponding positions on the component and substrate. Suitable for scenarios requiring point-like, quick fixing. Combined with... Figure 7 In some embodiments, snap fasteners 35 and Velcro 31 can be used for fixing at the same time.

[0072] Plug-in fixing: Matching plugs and sockets are set on the components and the base material respectively, and the connection and fixing are achieved by plugging and unplugging.

[0073] Clamping device fixation: Use detachable clips or clamps to hold the edge of the component to the substrate.

[0074] Magnetic fixing structure: Permanent magnets or magnetic materials are placed at corresponding positions on the component and the substrate. Suitable for applications requiring non-destructive and rapid positioning.

[0075] Sliding adjustment buckle fixation: Using an adjustment buckle with a sliding groove or slot, the component is inserted into the buckle, and the position of the component is changed and locked by sliding the buckle body.

[0076] Spring buffer buckle fixing: This type of fastener can be selected for localized locations.

[0077] Other methods: Depending on the specific application scenario, adhesive, screw connection (suitable for specific substrates), clamp, clip, snap, riveting, hook and other connection methods can be selected or combined.

[0078] The diverse fixing methods greatly improve the system's versatility and adaptability to different scenarios, allowing users to choose the most suitable fixing method based on factors such as substrate type, installation requirements, and disassembly frequency.

[0079] The core advantage of this utility model lies in its modularity. Users can:

[0080] Only the flexible heating component 10 is installed for environments that require heating but do not have high requirements for insulation.

[0081] Install only the flexible inflatable thermal insulation component 20 (after inflation) for use in scenarios requiring thermal insulation, moisture protection, or increased comfort (such as as a moisture-proof mat during summer camping).

[0082] The flexible inflatable thermal insulation component 20 and the flexible heating component 10 are stacked and installed (usually the thermal insulation component is close to the substrate and the heating component is on the inside) to obtain excellent thermal insulation and heating effects at the same time, which is suitable for cold environments.

[0083] When heating or insulation is not required (such as in summer), both components can be removed and stored.

[0084] This flexible modular combination method allows users to dynamically adjust the configuration according to the season, ambient temperature, activity needs, etc., which greatly improves the practicality and economy of the product and meets the application requirements of "flexible modular installation combination".

[0085] Example 2: A system applied to garment linings

[0086] This embodiment describes the application of the above system to a removable inner lining of clothing (such as jackets and vests).

[0087] Flexible heating component 10: Considering wearing comfort, the inner contact layer 11 is preferably made of a skin-friendly, anti-static material, such as silicone-coated fiberglass cloth. The heating layer 13 can be made of a highly flexible polymer heating material. The overall design aims for a thinner and more flexible profile. The elasticity and stretchability of the insulating encapsulation material are particularly important to accommodate body movements.

[0088] Flexible inflatable thermal insulation component 20: Made of thin TPU membrane material, with an optional honeycomb structure internally. The thickness after inflation can be controlled within a small range (e.g., 5-10mm) to avoid a bulky appearance.

[0089] Detachable fixing mechanism 30: Considering the convenience of putting on, taking off and washing the garment, it can be mainly fixed by snap buttons 35 or small magnetic structures. Male snap buttons / magnets are set on the edge of the component, and female snap buttons / magnets are set at the corresponding positions of the inner lining of the garment.

[0090] Applying this system to clothing gives ordinary garments adjustable heating and insulation functions, while maintaining their detachable and easy-to-maintain features, making them particularly suitable for outdoor activities and work in cold regions.

[0091] Example 3: Modular Assembly and System Expansion

[0092] To accommodate heating needs of different sizes or shapes (such as the inner walls of large tents, sleeping bags, vehicle seats, etc.), the system can be designed as multiple standard-sized flexible heating components 10 and / or flexible inflatable insulation components 20.

[0093] Electrical Connections: Each flexible heating element 10 may have mating waterproof connectors (such as the aforementioned waterproof aviation plugs or dedicated waterproof junction boxes) at both ends or on multiple sides. Users can easily connect multiple flexible heating elements 10 in series or parallel using these connectors (the specific connection method depends on the power supply and controller design) to form a heating area of ​​the desired size and shape. Finally, a single main interface connects to the power supply and thermostat. This design further enhances the system's modularity and scalability.

[0094] Physical connection: The spliced ​​flexible inflatable thermal insulation components 20 can be connected to each other by Velcro, snaps 35 or straps at the edges to form a whole thermal insulation layer.

[0095] Example 4: Heated Tent

[0096] This embodiment describes a heating tent that integrates the detachable modular flexible heating system of this invention.

[0097] Tent body: includes standard tent fabric (inner and / or outer tent) and support frame. The key is that its inner surface (usually the inner wall or bottom of the inner tent) is pre-designed or set with a structure that matches the removable fixing mechanism 30 on the heating / insulation components.

[0098] Heating system: includes one or more flexible heating components 10 and flexible inflatable insulation components 20, which are customized or optional according to the tent size.

[0099] Fixed implementation:

[0100] Velcro fastening: Sew a large area of ​​Velcro loops onto the inner wall of the tent where components will be installed. The user then attaches the heating / insulation components with hooks.

[0101] Anchoring hole fixation: Sew several webbing loops or install metal / plastic hanging points at corresponding positions on the inner wall of the inner tent. The user uses ropes 33 or hooks to attach the components with anchoring holes 32 to these points.

[0102] Guide channel securing: Slots, straps, or anchors are provided on the inner wall of the inner tent for securing the ends of support bars (such as part of a tent pole or additional flexible poles). The user installs the component with the support bars in place and secures the support bars.

[0103] Usage and Advantages: After setting up the tent, users can choose to install the flexible heating component 10, the flexible inflatable insulation component 20, or a combination of both, depending on the ambient temperature and their needs. After connecting the power supply and controller, users can enjoy a warm and comfortable tent interior. The components can be easily removed when disassembling the tent. Notably, the flexible inflatable insulation component 20 is very soft and compact after deflation, and can even be folded and packed with the tent without being removed, greatly simplifying the storage process. This type of heated tent not only significantly improves the camping experience and survival capabilities in cold and damp environments (especially for emergency rescue, military, and police), but also maintains high flexibility, portability, and ease of use, helping to overcome the shortcomings of traditional heated tents, such as being bulky, rigid, and difficult to maintain.

[0104] The above description is merely a preferred embodiment of this utility model. It should be noted that, for those skilled in the art, various combinations and variations can be made based on the alternative materials (such as heating layer and contact layer materials), alternative structures (such as the internal structure of the insulation layer), and alternative fixing methods disclosed in this specification, without departing from the principles of this utility model, resulting in several improvements and modifications. These improvements and modifications based on the core ideas of this utility model and the content disclosed in this specification should all be considered within the scope of protection of this utility model. For example, the shielding layer can be integrated with the inner contact layer 11 or the outer layer (if any) to form a composite conductive shielding fabric. The reflective layer 14 can also be integrally manufactured with the heating layer 13 or its encapsulation material.

[0105] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
