Description

Technical Field

[0001] This utility model relates to the field of outdoor tent design, and more particularly to outdoor tents based on polymer electrothermal film. Background Technology

[0002] In outdoor adventures, emergency rescues, and fieldwork, tents serve as temporary shelters, and their insulation performance in frigid environments is crucial. With the increasing popularity of outdoor activities and the rise of extreme weather, the insulation capabilities of traditional tents are insufficient, especially in environments below -10°C. Traditional tents, relying solely on physical insulation layers, often have internal temperatures below 0°C, failing to guarantee basic survival comfort and potentially even leading to frostbite. Therefore, developing new outdoor tents with active heating capabilities is key to improving survival capabilities in extreme environments.

[0003] Traditional tents typically use a single or double-layered fabric structure, relying solely on filling with cotton or air layers for passive insulation, lacking active heating capabilities. For example, a typical Oxford cloth tent can only maintain an internal temperature of around -3°C in a -5°C environment, and heat loss is rapid, requiring additional heating equipment (such as a gas stove). However, such equipment poses safety hazards due to open flames and the inconvenience of carrying fuel. While some tents are equipped with electric heating pads or heating wires, they suffer from uneven heating, high energy consumption, and safety risks. For instance, resistance wire heating is prone to fires due to localized overheating, and the complex wiring makes folding and storage difficult. Furthermore, the ventilation and sealing design of traditional tents is difficult to balance. Closing all openings in winter for warmth leads to internal moisture condensation, mold growth, and reduced insulation performance, while opening vents causes rapid heat loss.

[0004] In response to this technical problem, this application proposes an outdoor tent based on a polymer electrothermal film. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an outdoor tent based on a polymer electric heating film. This solves the problem that traditional tents rely solely on physical insulation and are insufficient for heating in low-temperature environments. It meets the needs of outdoor work and living in frigid regions, allows for on-demand air circulation adjustment, balances warmth and breathability, and prevents internal moisture buildup.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An outdoor tent based on a polymer electric heating film includes a tent body with multiple pre-set supports around its perimeter. Each pre-set support has a rainproof and sunshade fabric at its top. Two tent doors are located at both the front and rear ends of the tent body. The left tent door has a Velcro hook side on its front right side, and the right tent door has a Velcro loop side on its front left side. Ventilation windows are provided at the center of both ends of the tent body. Each of the two ventilation windows contains a curtain, which is connected to the tent body via a connecting component. The tent body has an interior waterproof layer, an interior heat insulation layer, an interior reflective layer, an interior polymer heating layer, and an interior flexible fabric layer.

[0008] Furthermore, the connecting component includes elastic connecting ropes disposed on opposite sides of the two shielding curtains, and each of the two elastic connecting ropes is fixedly connected to a preset fixing hook at opposite ends. Two preset limiting rings are fixedly connected to the left and right sides of the outdoor tent body.

[0009] Furthermore, the outer walls of the two preset fixed hooks are in contact with the opposite ends of the two preset limiting rings.

[0010] Furthermore, a heating film mat is installed at the bottom of the interior of the outdoor tent body, and the outer periphery of the outdoor tent body is connected to an external power source. A detachable temperature control module is installed on the outer wall of the external power source.

[0011] Furthermore, a flame-retardant layer is provided between the reflective layer and the polymer heating layer, and between the polymer heating layer and the flexible fabric layer, wherein the flame-retardant layer is mica paper.

[0012] Furthermore, the polymer heating layer is provided with silver-plated copper wires inside.

[0013] Furthermore, a transparent heating film is provided on the adjacent side of both of the aforementioned curtains.

[0014] Furthermore, a first magnet is provided at the right front end of the tent isolation door on the left end, and a second magnet is provided at the left front end of the tent isolation door on the right end. The first magnet and the second magnet attract each other to achieve automatic adsorption between the left and right ends of the tent isolation door.

[0015] Furthermore, the flexible fabric layer comprises an anti-wrinkle layer made of polyurethane material and a stretch layer formed by glass fiber weaving.

[0016] Furthermore, it also includes:

[0017] A solar cell array, wherein the solar panel array is mounted on the top of the outdoor tent body to convert solar energy into electrical energy;

[0018] An energy storage component is connected to the solar cell array and the polymer heating layer of the outdoor tent body, and is used to store the electrical energy converted by the solar cell array and drive the polymer heating layer to work.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model achieves composite insulation through a five-layer tent structure: an outer waterproof layer blocks rain and snow, a middle heat-insulating layer reduces heat loss, an aluminum foil reflective film reflects heat back into the interior, a polymer electric heating film heats up evenly after being energized, and an inner skin-friendly non-woven fabric enhances comfort. This design combines passive insulation with active heating, raising the temperature inside the tent in low-temperature environments. It solves the problem of traditional tents relying solely on physical insulation and providing insufficient warmth in low-temperature environments, thus meeting the needs of outdoor work and living in frigid regions.

[0021] 2. In this utility model, the tent isolation door uses Velcro closure with a rough surface, replacing traditional buckles or zippers. It automatically closes after the user enters or exits, shortening operation time, improving sealing, and reducing heat loss. A pre-reserved ventilation window switches between ventilation and closure modes via a pre-set fixed hook and upper and lower pre-set limit rings. An elastic connecting rope provides restraint when closed, ensuring no leakage in rain or snow, while also allowing for on-demand airflow adjustment to balance warmth and breathability, preventing internal moisture buildup.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an outdoor tent based on a polymer electrothermal film, comprising an outdoor tent body 1, with multiple pre-set supports 2 on the outer periphery of the outdoor tent body 1, and a rainproof and sunshade cloth 3 at the top of each pre-set support 2. Two tent isolation doors 4 are provided at both the front and rear ends of the outdoor tent body 1. A Velcro hook side 5 is provided on the front right side of the left tent isolation door 4, and a Velcro loop side 7 is provided on the front left side of the right tent isolation door 4. Pre-reserved ventilation windows 9 are provided at the middle of both ends of the outdoor tent body 1, and two curtains 8 are provided inside each of the two ventilation windows 9. Both curtains 8 are connected to the outdoor tent body 1 via pre-set fixing hooks 11. A first magnet is provided on the front right side of the left tent isolation door 4, and a second magnet is provided on the front left side of the right tent isolation door 4. The first magnet and the second magnet attract each other to achieve automatic adsorption between the left and right ends of the tent isolation doors 4. The outdoor tent body 1 has a heating film mat 6 installed at the bottom inside. The tent body 1 is connected to an external power source, and a detachable temperature control module is installed on the outer wall of the power source. The tent body 1 has a waterproof layer 14 inside, an insulation layer 15 inside the waterproof layer 14, a reflective layer 16 inside the insulation layer 15, a polymer heating layer 17 inside the reflective layer 16, and a flexible fabric layer 18 inside the polymer heating layer 17. Silver-plated copper wire is installed inside the polymer heating layer 17. Transparent heating films 13 are installed on the adjacent sides of the two blinds 8.

[0030] Specifically, the outdoor tent body 1 adopts an innovative five-layer tent structure: the outer waterproof layer 14 is made of PU-coated nylon, which can effectively block rain and snow from entering and ensure the interior is dry; the middle heat insulation layer 15 is filled with high-efficiency heat insulation materials such as pearl cotton or aerogel, which significantly reduces heat conduction to the outside; the reflective layer 16 uses the heat reflection characteristics of aluminum foil reflective film to reflect the lost heat back into the tent, improving thermal efficiency; the polymer heating layer 17 uses a polymer electric heating film as its core, which can quickly and evenly heat up after being powered on, achieving active heating; the inner flexible fabric layer 18 is made of skin-friendly non-woven fabric, which is comfortable to the touch when in direct contact with the human body and avoids the scorching feeling of traditional heating equipment. This five-layer structure forms a complete thermal management chain from waterproofing, heat insulation, reflection, heating to skin-friendly contact, which can raise the temperature inside the tent in low-temperature environments, solving the problem of traditional tents relying on passive heat preservation and insufficient heating in low-temperature environments.

[0031] On the other hand, for the safety of users, flame-retardant layers, specifically mica paper, are provided between the reflective layer 16 and the polymer heating layer 17, and between the polymer heating layer 17 and the flexible fabric layer 18. This prevents the polymer heating layer 17 in the outdoor tent body 1 from overheating and causing a fire.

[0032] On the other hand, the flexible fabric layer 18 includes an anti-wrinkle layer made of polyurethane material and a tensile layer formed by glass fiber weaving. The anti-wrinkle layer improves the wrinkle resistance of the outdoor tent body 1, and the tensile layer improves the tensile properties and strength of the outdoor tent body 1, solving the problems of low strength and poor wrinkle resistance of outdoor tent materials in the prior art.

[0033] On the other hand, considering that users often face problems such as power shortages and emergency power needs when using outdoor tents for camping, the outdoor tents are also equipped with solar panel arrays and energy storage components. The solar panel array is set on the top of the outdoor tent body 1 to convert sunlight into electrical energy; the energy storage component is connected to the polymer heating layer 17 of the outdoor tent body 1, which is used to store the electrical energy converted by the solar panel array and drive the polymer heating layer 17 to work.

[0034] Reference Figure 3 Two curtains 8 are each equipped with an elastic connecting rope 10 on one side of their respective sides. Each of the two elastic connecting ropes 10 is fixedly connected to a pre-set fixing hook 11 at one end. The outdoor tent body 1 is fixedly connected to two pre-set limiting rings 12 on both the left and right sides. The outer walls of the two pre-set fixing hooks 11 are in contact with the opposite ends of the two pre-set limiting rings 12.

[0035] Specifically, the tent's sealing and ventilation design balances convenience and environmental adaptability: the front and rear tent doors 4 are sealed to corresponding components via Velcro 7, automatically closing without manual operation after the user enters or exits, simplifying the closing process while enhancing sealing and reducing heat loss. Ventilation windows 9 on both sides are secured by pre-set hooks 11 that engage with pre-set top or bottom limiting rings 12, allowing for flexible switching between ventilation and closure modes. When open, the hooks engage with the top limiting ring, fixing the curtain 8 to the top and ensuring smooth airflow; when closed, the hooks engage with the bottom limiting ring, and the elastic binding force of the elastic connecting rope 10 ensures the curtain fits tightly against the window, effectively preventing rain and snow intrusion. This design satisfies the tent's air circulation needs, preventing moisture buildup, while maintaining good sealing in harsh weather conditions, improving reliability in complex environments.

[0036] Working principle: The core of this utility model is to achieve active heating through a multi-layer tent structure and a polymer electric heating film heating system. At the same time, it is equipped with a flexible power supply and temperature control module to solve the problem of heating traditional tents in cold environments.

[0037] Firstly, the outdoor tent body 1 is composed of a five-layer tent structure. The outer waterproof layer 14 uses waterproof fabric such as PU-coated nylon to prevent rain and snow from penetrating. The middle heat insulation layer 15 is filled with heat insulation cotton such as pearl cotton or aerogel to reduce heat loss to the outside. The reflective layer 16 uses aluminum foil reflective film to reflect heat back into the tent, improving thermal efficiency. The core component of the polymer heating layer 17 is a polymer electric heating film, which heats up quickly and evenly after being powered on. The inner flexible fabric layer 18 is a soft fabric such as skin-friendly non-woven fabric, which comes into direct contact with the human body and improves comfort.

[0038] Meanwhile, the tent isolation doors 4 at the front and rear ends of the outdoor tent body 1 are closed by attaching the hook side 5 and the loop side 7 of Velcro. This reduces the complicated opening and closing process when the user enters the outdoor tent body 1, and also allows the two tent isolation doors 4 to automatically close after the user enters. The reserved ventilation windows 9 on both sides of the outdoor tent body 1 allow for the circulation of internal and external air. When the curtain 8 is opened, the operator can engage the preset fixing hook 11 on the curtain 8 with the preset limiting ring 12 at the top of the outdoor tent body 1 to allow for smooth circulation and exchange of internal and external air. When it is necessary to close the reserved ventilation windows 9, the operator needs to engage the preset fixing hook 11 with the preset limiting ring 12 at the bottom. Under the elasticity of the elastic connecting rope 10, the curtain 8 can be restrained, thereby making the curtain 8 close more tightly and preventing rain and snow from entering the outdoor tent body 1 in rainy or snowy weather.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
