Description

Technical Field

[0001] This application relates to the field of tent manufacturing technology, and in particular to a camp tent. Background Technology

[0002] Camp tents can be quickly assembled and provide temporary shelter. In the field of military camp tents, their functions include: long-term / short-term outdoor accommodation during field expeditions, camping, exploration, construction, disaster relief, and flood control. Existing military camp tents use a steel frame structure, making them safe and reliable, capable of withstanding both level 8 winds and 6 cm of snow load. The roof fabric of military camp tents is made of three-proof fabric, effectively blocking rain, snow, and ultraviolet radiation; the walls are made of thickened cotton canvas, with thickened felt in the middle and a white cloth lining.

[0003] The choice of fabric for the roof and walls in existing military camp tents results in generally poor cold-weather protection, leading to low internal temperatures and an inability to provide a warm and comfortable living environment for occupants. This makes conventional camp tents unsuitable for the harsh, cold environments of high-altitude regions. To overcome this problem, occupants typically use heated sleeping bags. While this addresses the issue of the tents' limited cold-weather protection, it also increases the individual's load, hindering mission execution.

[0004] Alternatively, heaters can be installed inside the camping tents, using resistance wires to generate heat and raise the internal temperature. These heaters are technologically mature and inexpensive, but they have the following drawbacks: 1. Heat radiation hazards; 2. Electromagnetic radiation hazards; 3. They are relatively heavy and inconvenient to move; 4. The heating wires can dry out the tent's interior because traditional heating wires primarily use resistance heating, dissipating heat mainly through conduction, which reduces the air's moisture content, leading to dryness and negatively impacting health. Therefore, the applicant provides a camping tent that creates a warm and comfortable living environment. Utility Model Content

[0005] To address the problems existing in current camping tents, this application provides a camping tent.

[0006] The camping tent provided in this application is achieved through the following technical solution: A camping tent includes an aluminum alloy frame structure, a detachable intermediate insulation layer connected to the aluminum alloy frame structure, and a waterproof canvas detachably connected to the intermediate insulation layer. The intermediate insulation layer is composed of several insulation cotton units detachably connected to the aluminum alloy frame structure. Several suspended far-infrared heating modules are detachably connected within the aluminum alloy frame structure.

[0007] The camp tent in this application uses a self-designed suspended far-infrared heating module, with the flexible electric heating film in the suspended far-infrared heating module as the heat source, which can create a warm and comfortable living environment, and is lightweight, easy to move and assemble.

[0008] Preferably, the suspended far-infrared heating module includes a suspended aluminum alloy shell, an inner frame, a circuit board mounting frame, and a high-temperature resistant electric heating film. The inner frame and the circuit board mounting frame are detachably connected to form a base frame. The suspended aluminum alloy shell is detachably connected to the outside of the base frame. A circuit board is detachably connected inside the circuit board mounting frame, and the circuit board is connected to a power supply line. The high-temperature resistant electric heating film is connected inside the inner frame.

[0009] Preferably, the inner skeleton has a heat-conducting window; the inner skeleton is connected to an aramid mesh; the aramid mesh is connected to the heat-conducting window of the inner skeleton to prevent users from directly contacting the high-temperature resistant electric heating film and reduce potential safety hazards.

[0011] The far-infrared heating module heats the environment inside the tent through far-infrared radiation, which can directly affect the human body. The wavelength of the emitted far-infrared light highly overlaps with the wavelength of the far-infrared light emitted by the human body, forming a resonance absorption effect, rather than heating the air and then transferring heat to the human body. This makes the body feel more comfortable and creates a warm and comfortable living environment.

[0012] Preferably, the suspended far-infrared heating module further includes several air-guiding fans, which are connected to the periphery of the suspended aluminum alloy housing.

[0013] By using a deflector fan, airflow within the tent environment can be enhanced, allowing cool air to rise and forcing hot air to sink. This strengthens convection, evens out the temperature distribution within the tent, improves heating efficiency, and makes the tent environment more uniform and faster, resulting in a more comfortable experience.

[0014] Preferably, a ring A is fixedly connected to each of the four corners of the side of the rear heat-conducting window of the suspended aluminum alloy shell; several rings B are fixedly connected to the aluminum alloy keel structure; and the safety buckle is fastened into the rings A and B respectively, so that the suspended far-infrared heating module can be detachably connected to the aluminum alloy keel structure through the safety buckle, which facilitates the quick assembly of the camping tent.

[0015] Preferably, the insulation unit includes an outer bag, an insulation felt filled inside the outer bag, and a round-faced hook and loop fastener A fixedly connected to one side of the outer bag. The outer side of the aluminum alloy keel structure is fixedly connected with a hook and loop fastener A. The round-faced hook and loop fastener A are fastened together with the hook and loop fastener A, so that the insulation unit can be detachably connected to the aluminum alloy keel structure, which facilitates the quick assembly of the camping tent.

[0016] Preferably, the opening of the outer bag is sewn with a zipper; the outer bag is made of Oxford cloth; the outer layer of the outer bag is coated with a three-proof coating and cured to form a protective layer; the insulation felt includes aluminum foil insulation cotton and aerogel insulation felt filled inside the outer bag.

[0017] By adopting the above technical solutions, the camp tents are given excellent cold-weather insulation performance.

[0018] Preferably, the outer pocket is fixedly connected to the side of the loop fastener A with a loop fastener B; the waterproof canvas is fixedly connected to the hook fastener B with a barbed surface; the loop fastener B and the hook fastener B are fastened together, realizing the detachable connection between the waterproof canvas and the middle insulation layer, which facilitates the quick assembly of the camping tent.

[0019] Preferably, the bottom of the aluminum alloy keel structure is fixedly connected with several fixing buckles; the fixing buckles are connected with tent pegs; the aluminum alloy keel structure is firmly anchored to the ground by the tent pegs.

[0020] In summary, this application has the following advantages: 1. The camp tent in this application uses a self-designed suspended far-infrared heating module, with the flexible electric heating film in the suspended far-infrared heating module as the heat source, which can create a warm and comfortable living environment, and is lightweight, easy to move and assemble.

[0021] 2. The camp tent in this application has good cold-proof and heat-insulating properties and is suitable for the frigid environment of high-altitude areas.

[0022] 3. The suspended far-infrared heating module in this application is relatively lightweight and easy to transport and assemble. Attached Figure Description

[0032] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Example: Refer to Figure 1A camping tent includes an aluminum alloy frame structure 1, a detachable intermediate insulation layer 2 connected to the aluminum alloy frame structure 1, a waterproof canvas 3 detachably connected to the intermediate insulation layer 4, and several suspended far-infrared heating modules 4. The intermediate insulation layer 2 is composed of several detachable insulation cotton units 20 connected to the aluminum alloy frame structure 1, providing the camping tent with good cold-weather insulation while also facilitating quick assembly. The suspended far-infrared heating modules 4 are detachably connected inside the aluminum alloy frame structure 1 and can be detachably fastened to the aluminum alloy frame structure 1 inside the camping tent.

[0034] Reference Figure 1 and Figure 2 The aluminum alloy keel structure 1 is assembled using commercially available standard aluminum alloy square tubes and scaffolding connectors. The aluminum alloy keel structure 1 includes two frame-type skeletons 101, horizontally connected aluminum alloy square tubes 102, and vertically connected aluminum alloy square tubes 103. During assembly, the horizontally connected aluminum alloy square tubes 102 are assembled between the two frame-type skeletons 101 using scaffolding connectors. Then, the vertically connected aluminum alloy square tubes 103 are assembled between adjacent horizontally connected aluminum alloy square tubes 102 using scaffolding connectors, thus completing the construction of the aluminum alloy keel structure 1.

[0035] Reference Figure 1 and Figure 2 The aluminum alloy keel structure 1 is surrounded by a series of horizontally connected aluminum alloy square tubes 12 and vertically connected aluminum alloy square tubes 13, forming several assembly units for assembling the insulation cotton units 20. Specifically, the horizontally connected aluminum alloy square tubes 102 and vertically connected aluminum alloy square tubes 103 are all fixedly connected to hook-and-loop fasteners by adhesive, and the insulation cotton units 20 are fixedly connected to round-textured hook-and-loop fasteners by sewing. The round-textured hook-and-loop fasteners are fastened to the hook-and-loop fasteners, which allows the insulation cotton units 20 to be detachably connected to the aluminum alloy keel structure 1, facilitating the quick assembly of the insulation cotton units 20 onto the aluminum alloy keel structure 1.

[0036] Reference Figure 1 and Figure 2The frame frame 101 is assembled using commercially available standard aluminum alloy square tubing and ceiling fitting connectors. Hook and loop fasteners are glued to the aluminum alloy square tubing of the frame frame 101, and corresponding shaped insulation units 20 are sewn onto round loop fasteners. The round loop fasteners and hook and loop fasteners are connected via hook and loop fasteners, allowing the insulation units 20 to be detachably connected to the aluminum alloy keel structure 1. Fixing the insulation units 20 to all sides of the aluminum alloy keel structure 1 effectively improves its cold-weather insulation performance. The frame frame 11 has two insulation units 20 serving as "entry doors," which are connected by a zipper for closure or opening. The other three sides are connected to the frame frame 101 via round loop fasteners and hook and loop fasteners.

[0037] Waterproof canvas 3 is the commercially available standard awning fabric with sun protection and waterproof function.

[0038] Reference Figure 3 and Figure 4 The suspended far-infrared heating module 4 includes a suspended aluminum alloy housing 41, an inner frame 42, a circuit board mounting frame 43, a high-temperature resistant electric heating film 44 connected inside the inner frame 42, and a guide fan 47 detachably connected to the bottom periphery of the suspended aluminum alloy housing 41. The inner frame 42 and the circuit board mounting frame 43 are detachably connected to form a base frame 40. The suspended aluminum alloy housing 41 is detachably connected to the outside of the base frame 40.

[0039] Reference Figure 3 and Figure 4 A circuit board is detachably connected to the circuit board mounting frame 43 via screws, and the circuit board is connected to a power connection cable 45. The power connection cable 45 can be connected to a portable power source placed inside the camping tent. The airflow direction of the air guide fan 47 is aligned with the opening direction of the heat conduction window 400. A heat conduction window 400 is formed within the inner frame 42. An aramid mesh fabric 46 is connected to the inner frame 42. The aramid mesh fabric 46 is connected to the heat conduction window 400 of the inner frame 42 to prevent the user from directly contacting the high-temperature resistant electric heating film 44 and causing a safety accident.

[0040] Considering the mountainous terrain of high-altitude areas, large portable power banks are inconvenient to carry. Therefore, camp tents can be equipped with solar power generation equipment. This solar power generation equipment utilizes conventional technology and consists of solar photovoltaic panels, a solar controller, a solar battery bank, and a solar inverter. The power connection cable 45 can be connected to the solar battery bank, which provides power to the high-temperature resistant electric heating film 44.

[0041] Reference Figure 3 and Figure 4The high-temperature resistant electric heating film 44, circuit board, power connection cable 45, and mobile power supply or solar battery pack form a current loop. When the high-temperature resistant electric heating film 44 is powered on, it generates heat and releases heat into the interior environment of the tent. The high-temperature resistant electric heating film 44 also generates far-infrared heating when powered on, ensuring that the camp tent has a good cold-proof and warming effect.

[0042] The high-temperature resistant electric heating film 44 is our company's latest research and development of flexible electric heating film products.

[0043] Reference Figure 4 and Figure 5 The high-temperature resistant electric heating film 44 includes an aramid electric heating film 441, a conductive electrode 442, and a heat-insulating high-temperature resistant insulating film 443. The heat-insulating high-temperature resistant insulating film 443 is fixedly connected to the aramid electric heating film 441. The conductive electrode 442 is fixedly connected to the surface of the aramid electric heating film 441 facing away from the heat-insulating high-temperature resistant insulating film 443. This high-temperature resistant electric heating film product was patented on February 29, 2024, with application number 2024102260153, entitled "A High-Temperature Resistant Electric Heating Film and Its Preparation Method," which discloses the formula and preparation method of the high-temperature resistant electric heating film. The designed steady-state heating temperature of the high-temperature resistant electric heating film is 120-280℃, the temperature uniformity ΔT is 0.6-1.32, the maximum instantaneous heating rate is 1.15-3.41℃ / s, and the surface resistance is 67.8-6.21*10⁻⁶. 4 Ω / sq.

[0044] The electric heating film used in this application is the high-temperature resistant electric heating film disclosed in Example 5 of the invention patent application number 2024102260153. It has a high steady-state temperature and heating rate and good heating uniformity, which can give the camping tent the effect of rapid heating.

[0045] Reference Figure 3 and Figure 4 This section details the structure of each component of the suspended far-infrared heating module 4. The suspended aluminum alloy housing 41 consists of a base plate and a U-shaped frame. During assembly, the U-shaped frame is fitted onto the outside of the base frame 40 and then secured with bolts. The base plate is connected to the bottom of the circuit board mounting frame 43 by screws, facilitating the assembly of the suspended far-infrared heating module 4.

[0046] Reference Figure 3 and Figure 4The inner frame 42 includes a top inner frame 421, a bottom inner frame 422, and a connector 423 detachably connected between the top inner frame 421 and the bottom inner frame 422. The top inner frame 421 and the bottom inner frame 422 have the same structure. Taking the top inner frame 421 as an example, the top inner frame 421 is an aluminum alloy frame spliced ​​together by four aluminum alloy profile strips. Adjacent aluminum alloy profile strips are first snapped together for positioning and then detachably fixed together with screws to form the top inner frame 421.

[0047] Reference Figure 3 and Figure 4 During assembly, the top inner frame 421 and the bottom inner frame 422 are both snapped onto the circuit board mounting frame 43. The top inner frame 421 and the bottom inner frame 422 are fixedly connected to the circuit board mounting frame 43 by screws. Finally, the connecting piece 423 is detachably connected between the top inner frame 421 and the bottom inner frame 422 by screws, and the assembly forms the inner frame 42.

[0048] Reference Figure 3 and Figure 4 The connector 423 in the inner frame 42 is used to limit and fix the high temperature resistant electric heating film 44, so that the high temperature resistant electric heating film 44 is fixedly connected between the top inner frame 421 and the bottom inner frame 422, that is, the high temperature resistant electric heating film 4 is set inside the inner frame 42.

[0049] Reference Figure 4 and Figure 6 The structure of the connector 423 is as follows: The connector 423 comprises an aluminum alloy frame 4231, a first connecting piece 4232, and a second connecting piece 4233. The first connecting piece 4232 is integrally extruded onto the top of the aluminum alloy frame 4231, and the second connecting piece 4233 is integrally extruded onto the bottom of the aluminum alloy frame 4231. The first connecting piece 4232 is connected to the outer periphery of the top inner frame 421 by screws, and the second connecting piece 4233 is connected to the bottom inner frame 422 by screws. A reinforcing rib 4234 is integrally extruded inside the aluminum alloy frame 4231. An electric heating film connecting piece 4235 is welded to the outer surface of the aluminum alloy frame 4231.

[0050] Reference Figure 4 and Figure 6The electric heating film connecting piece 4235 includes a connecting straight piece 42351 and a U-shaped clamping piece 42352. The connecting straight piece 42351 is integrally extruded onto the outer side of the aluminum alloy frame 4231 and is parallel to the horizontal plane. The bottom of the U-shaped clamping piece 42352 is integrally extruded onto the end of the connecting straight piece 42351 facing away from the outer side of the aluminum alloy frame 4231. The high-temperature resistant electric heating film 44 is limited and positioned inside the U-shaped space formed by the U-shaped clamping piece 42352. A ceramic fastening bolt 42353 is threaded onto the side of the U-shaped clamping piece 42352. One end of the fastening bolt 42353 abuts against the surface of the heat-insulating high-temperature resistant insulating film 443, enabling the high-temperature resistant electric heating film 44 to be detachably connected to the fitting 423. To improve the installation stability of the high-temperature resistant electric heating film 44, a TPU U-shaped elastic gasket 42354 is fixedly connected to the U-shaped clip 42352 with adhesive. The U-shaped elastic gasket 2354 is fixedly connected to the U-shaped space of the U-shaped clip 42352 with adhesive. When installing the high-temperature resistant electric heating film 44, first, manually pry open the U-shaped clip 42352 and place it between the high-temperature resistant electric heating film 44 and the U-shaped elastic pad 2354. After loosening the U-shaped clip 42352, the high-temperature resistant electric heating film 44 is snapped into place between the U-shaped elastic pads 42354. Tighten the fastening bolt 42353 so that the bottom end of the fastening bolt 42353 abuts against the upper surface of the U-shaped elastic pad 42354, and the lower surface of the U-shaped elastic pad 42354 contacts the upper surface of the heat-insulating high-temperature resistant insulating film 443. This completes the fixation of the high-temperature resistant electric heating film 44 to the electric heating film connecting piece 4235.

[0051] Reference Figure 3 and Figure 7 The detachable connection between the suspended far-infrared heating module 4 and the aluminum alloy keel structure 1 is achieved through the following structure: Rings A411 are fixedly connected to the four corners of the side of the suspended aluminum alloy shell 41 behind the heat-conducting window 400. Several rings B412 are fixedly connected to the aluminum alloy keel structure 1. During assembly, safety buckles 48 are engaged with the rings A411 and B412 respectively, allowing the suspended far-infrared heating module 4 to be detachably connected to the aluminum alloy keel structure 1 via the safety buckles 48, effectively improving the assembly efficiency of the suspended far-infrared heating module 4.

[0052] There are three ways to install the suspended far-infrared heating module 4: ① The suspended far-infrared heating module 4 can be detachably connected to the inner periphery of the aluminum alloy keel structure 1 via a safety buckle 48; ② The suspended far-infrared heating module 4 can be detachably connected to the inner top of the aluminum alloy keel structure 1 via a safety buckle 48; ③ The suspended far-infrared heating module 4 can be detachably connected to both the inner periphery and inner top of the aluminum alloy keel structure 1 via a safety buckle 48.

[0054] Reference Figure 1 and Figure 8 The outer bag 201 has a zipper 2011 sewn at its opening. Unzipping 2011 allows insulation felt 202 to be filled inside the outer bag 201. The outer bag 201 is made of Oxford cloth. To prevent the waterproof canvas 3 (awning fabric) from leaking and damaging the insulation unit 20, the outer bag 201 is coated with a commercially available waterproof coating, which, after curing, forms a protective layer 2010.

[0055] Reference Figure 1 and Figure 8 The insulation felt 202 filled inside the outer pocket 201 includes aluminum foil insulation cotton 2021 and aerogel insulation felt 2022, giving the camp tent good cold-proof and heat-insulating performance.

The surface of the waterproof canvas 3 facing the outer layer of the aluminum alloy keel structure 1 is fixedly connected to the outer hook and loop fastener B206 with adhesive. The round loop hook and loop fastener B205 and the outer hook and loop fastener B206 are connected by hook and loop fasteners, which realizes the detachable connection between the waterproof canvas 3 and the middle insulation layer 2. This facilitates the assembly, disassembly and maintenance of the waterproof canvas 3, and also provides a good fixing effect for the waterproof canvas 3, preventing the connection stability of the waterproof canvas 3 from being damaged by strong winds.
