Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of personal outdoor equipment, and in particular to a novel heating sleeping bag capable of preventing radar and thermal imaging. Background Art
[0002] A sleeping bag is a bag you sleep in. Most sleeping bags on the market are labeled with comfort and maximum temperatures. Comfort temperature is a range of temperatures the user experiences throughout a night's sleep, with a maximum and minimum. Maximum comfort temperature is when the user feels warm in the bag but not sweating profusely. This is generally defined as the bag's zipper open, arms hanging out, and the head of the bag loosened.
[0003] Traditional sleeping bags rely primarily on the insulating properties of their fillings (such as down and synthetic cotton) to maintain body temperature. These materials offer limited warmth in extremely cold environments and lack the ability to actively heat the body. Their outer materials typically lack electromagnetic or infrared stealth, making them easily detectable by radar and thermal imaging equipment. Sleeping bags with integrated electric heating elements (such as carbon fiber and metal resistance wire) are now commercially available, actively providing heat and enhancing comfort and survivability. However, the metal wires, connectors, controllers, and even the heating wires themselves within these bags create a strong radar scatterer (RCS), making them easily detectable and located by radar. The heating elements generate heat, and even with insulation, this heat inevitably dissipates through the sleeping bag's surface, creating a significant thermal infrared signature that can be easily detected by thermal imaging cameras. This signature is particularly pronounced in cold environments or at night, acting like a "beacon." Some controllers may also generate weak electromagnetic radiation when operating, increasing the risk of detection by electronic reconnaissance equipment. Technologies such as radar absorbing materials (RAM), low-infrared emissivity coatings / materials, and thermal insulation materials have been widely used in the stealth of large equipment such as aviation and ships. However, integrating these technologies effectively, lightweightly, and comfortably into sleeping bags for individual soldiers, which require flexibility, retractability, and active heat sources, faces huge challenges. Existing sleeping bag products do not yet have an effective solution to the compatibility between heating and radar / thermal infrared stealth.
[0004] To this end, we propose a new type of heated sleeping bag that is radar-proof and thermal-proof. Summary of the Invention
[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a new type of heated sleeping bag that can protect against radar and thermal imaging.
[0006] To achieve the above objectives, the present invention adopts the following technical solutions: a novel heated sleeping bag that is resistant to radar and thermal imaging, comprising a sleeping bag body and a heating control system. The sleeping bag body comprises an outer layer, an inner wall of the outer layer is provided with an intermediate layer, an inner wall of the intermediate layer is provided with an inner layer, the outer layer comprises a radar absorbing layer, and the inner wall of the radar absorbing layer is fixedly connected to the outer wall of the intermediate layer, the outer wall of the radar absorbing layer is coated with an infrared low-emission layer, the intermediate layer comprises a high-efficiency thermal insulation material layer, and the outer wall of the high-efficiency thermal insulation material layer is fixedly connected to the inner wall of the radar absorbing layer, and the inner wall of the high-efficiency thermal insulation material layer is fixedly installed with a non-metallic flexible electromagnetic shielding layer. The heating control system comprises a power module, a control module, and an operating module, the power module, the control module, and the operating module being electrically connected by non-metallic conductive fibers, specifically carbon fiber bundles. The power module comprises a rechargeable lithium battery pack and a flexible non-metallic low RCS shell. The control module comprises a non-metallic circuit board, a temperature sensor, an intelligent temperature control circuit, and a non-metallic flexible heating element, and the non-metallic flexible heating element is located inside the outer layer. The operating module comprises a control switch and a wired remote control.
[0007] Preferably, the outer layer is made of cotton, the radar absorbing layer is made of modified rubber graphene composite material, the infrared low-emission layer is made of metal foil silicon carbide polymer coating, and the high-efficiency thermal insulation material layer is made of nano aerogel felt.
[0008] Preferably, the non-metallic flexible electromagnetic shielding layer is made of a carbon nanotube film.

[0015] The present invention provides a new type of heated sleeping bag that is radar-proof and thermal-proof. It has the following beneficial effects:
[0016] 1. This is a new type of heated sleeping bag that is resistant to radar and thermal imaging. By setting up a sleeping bag body and a heating control system, the sleeping bag body not only ensures the thermal insulation performance of the sleeping bag, but also realizes multiple stealth functions of anti-radar detection and anti-thermal imaging.

[0018] 3. This new type of heated sleeping bag that is resistant to radar and thermal imaging uses a combination of a high-efficiency thermal insulation material layer and a non-metallic flexible electromagnetic shielding layer in the middle layer. It not only achieves a good thermal insulation effect, but also further enhances the electromagnetic stealth capability of the sleeping bag, ensuring the safety of the user in extreme environments.

It has a heating control system that uses non-metallic and low radar cross-section materials, effectively avoiding the radar detection risks brought by traditional metal heating elements. At the same time, the design of the intelligent temperature control circuit achieves constant temperature heating, improving the user's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Working principle of the present invention:
[0037] During use, the user sends commands to the control module via a wired remote control. The control module then controls the non-metallic flexible heating element to heat the sleeping bag. A temperature sensor monitors the temperature inside the sleeping bag in real time and feeds the temperature signal back to the intelligent temperature control circuit, which adjusts the heating power of the non-metallic flexible heating element within a preset temperature range to achieve constant heating. Simultaneously, the radar absorbing layer effectively absorbs radar waves, reducing the sleeping bag's radar cross section (RCS). The low-infrared emissivity layer reduces the intensity of infrared radiation. The non-metallic flexible electromagnetic shielding layer shields electromagnetic waves, further reducing the risk of detection by radar and electronic reconnaissance equipment. This heating control system utilizes non-metallic and low-radar cross-section (RCS) materials, effectively eliminating the radar detection risk associated with traditional metal heating elements. The combination of the high-efficiency thermal insulation layer, the radar absorbing layer, and the low-infrared emissivity layer not only provides excellent thermal insulation but also significantly reduces the sleeping bag's infrared signature, enabling it to maintain good stealth even in cold environments or at night. Furthermore, the non-metallic flexible electromagnetic shielding layer further enhances the sleeping bag's electromagnetic stealth, ensuring user safety in complex electromagnetic environments.
