Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stealth bionics, and in particular relates to a stealth cloak. Background Art
[0002] With the development of reconnaissance and precision-guided technologies, important stealth targets are facing increasing threats. Once a stealth target is discovered, it means it will be destroyed. In particular, personnel engaged in covert confrontation face a higher possibility of being discovered by the enemy. Therefore, stealth protection has become an important means to improve survivability.
[0003] Judging from the current status of camouflage or stealth technology at home and abroad, the currently used invisible cloaks are difficult to meet the needs of practical applications, mainly in the following aspects:
[0004] (1) Traditional stealth cloaks have poor stealth effects on thermal targets. This is because the infrared emissivity of traditional low-emissivity materials is generally difficult to reach below 0.55, resulting in low thermal radiation suppression capabilities.
[0005] (2) Traditional infrared stealth materials are not conducive to the heat dissipation of hot targets. Due to the use of more metal materials, traditional infrared stealth materials have strong reflections over the entire infrared band, which may lead to heat dissipation difficulties.
[0006] (3) Traditional stealth cloaks are not good enough to resist optical reconnaissance. Since they only use camouflage colors, the stealth methods are not rich enough and the cloaks are not well integrated with the background, which makes the optical stealth effect poor.
[0007] (iv) Traditional invisible cloaks are not waterproof and can easily get wet when it rains, causing inconvenience to the user. Utility Model Content
[0008] The utility model aims to provide an invisible cloak which has the advantages of being easy to put on and take off, and being convenient to store and carry, while taking into account the infrared invisible and waterproof and fireproof functions.
[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0010] A stealth cloak comprises a cloak body, hidden pockets, a hat and a storage bag; the stealth cloak is made by cutting and sewing infrared stealth fabric; the infrared stealth fabric is made of photonic crystal coated base fabric; the cloak body and the hat are an integrated structure.
[0011] As a possible implementation method, the inner layer of the photonic crystal coated base fabric is also coated with a waterproof layer.
[0012] As a possible implementation method, a flame retardant layer is further provided between the base fabric and the waterproof layer; the flame retardant layer is formed by cross-linking the base fabric of the infrared stealth fabric with a phosphorus silicon-based nano flame retardant by a plasma induction method; or,
[0013] The flame retardant layer is formed by alternately depositing graphene and casein on the base fabric of the infrared stealth fabric.
[0014] As a possible implementation method, the inner layer of the photonic crystal coated base fabric is sprayed or rolled with a fabric waterproofing agent to form a waterproof layer.
[0015] As a possible implementation manner, the fabric waterproof agent includes at least one of a silicone fabric waterproof agent, an acrylic fabric waterproof agent, a polyurethane fabric waterproof agent, and a fluorocarbon fabric waterproof agent.
[0016] As a possible implementation method, the invisibility cloak also includes: multiple groups of three-dimensional bionic layers sewn on the outer surface of the cloak body and the hat; the three-dimensional bionic layers adjacent to each other overlap head to tail; the material of the three-dimensional bionic layers is the same as that of the cloak body and the hat.
[0017] As a possible implementation manner, the three-dimensional bionic layer is at least one of a bionic strip, a bionic grass or a bionic leaf.
[0018] As a possible implementation method, the invisibility cloak adopts a one-piece pullover design and an open tube design at the head of the pullover; buttons and eyelets are set on the side.

[0020] As a possible implementation, an elastic cord for adjusting the size of the hat opening is provided at the brim of the hat.
[0021] Compared with the prior art, the utility model has the following effects:
[0022] 1. The stealth cloak provided by the utility model adopts a photonic crystal coated base fabric. Due to the bandgap characteristics of the photonic crystal, the required low emissivity can be achieved in a specific band. Thus, the requirements for thermal infrared stealth of high-temperature targets are met, the problem of difficulty in stealth of high-temperature targets is solved, and the overall mid-infrared and far-infrared camouflage effects of the stealth cloak can be significantly improved.
[0023] 2. The utility model is made of photonic crystal coated base fabric. Since the photonic crystal is a micron-level coating, the infrared stealth fabric has the advantages of being very light and thin while ensuring that it can withstand high breaking force and tearing force, and is easy to carry.
[0024] 3. The utility model not only realizes infrared stealth but also solves the heat dissipation problem of hot targets. Since the photonic crystal stealth material has a low emissivity only in two atmospheric windows and a higher emissivity outside the atmospheric windows, the heat of the target can be dissipated as usual through the band outside the atmospheric windows, thereby avoiding the problem of heat accumulation of hot targets.

[0033] In order to facilitate the clear description of the technical solutions of the embodiments of the present utility model, in the embodiments of the present utility model, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and do not limit their order. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit them to be different.
[0034] It should be noted that in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0035] In the present utility model, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or plural.
[0036] With the development of reconnaissance and precision guidance technology, traditional stealth cloaks can no longer meet the needs of practical applications. In order to solve the above problems, the utility model provides a stealth cloak that has the advantages of being easy to put on and take off, and easy to store and carry while taking into account infrared stealth, waterproof and fireproof functions.
[0037] See also Figure 1 The utility model provides an invisible cloak, which includes a cloak body 10, a hidden pocket, a hat 11 and a storage bag; the invisible cloak is made by cutting and sewing infrared invisible fabric; the infrared invisible fabric is made of photonic crystal coated base fabric; the cloak body 10 and the hat 11 are an integrated structure.
[0038] The infrared stealth fabric used to make the stealth cloak is made of photonic crystal coated base fabric. Due to the bandgap characteristics of photonic crystals, the required low emissivity can be achieved in a specific band. The emissivity can be lower than 0.05, thus meeting the requirements of thermal infrared (3-5μm and 8-14μm bands) stealth for high-temperature targets, solving the problem of high-temperature target stealth difficulties, and significantly improving the overall mid-infrared and far-infrared camouflage effects of the stealth cloak.
[0039] Since photonic crystals are micron-level coatings, infrared stealth fabrics are very light and thin while being able to withstand high breaking and tearing forces. Therefore, stealth cloaks made of this infrared stealth fabric are also strong and durable, light and portable. In addition, since photonic crystal stealth materials have low emissivity only in two atmospheric windows, and have a higher emissivity outside the atmospheric windows, the heat of the target can be dissipated as usual through the bands outside the atmospheric windows, thus avoiding the problem of heat accumulation of hot targets.
[0040] As a possible implementation method, the storage bag is fixed to the back collar of the cloak through a strip; the hidden pocket is set at the back neck of the hat.
[0041] The storage bag is used to store the main body of the cloak and the hat. When not in use, the main body of the cloak and the hat are folded and put into the storage bag. It is small in size and easy to carry. The hidden pocket is set at the back neck of the hat. When in use, the storage bag is placed in the hidden pocket, which does not affect the stealth effect and the storage bag is not easy to lose.
[0042] As a possible implementation manner, the inner layer of the photonic crystal coated base fabric is also coated with a waterproof layer.
[0043] As a possible implementation method, the surface of the photonic crystal coated base fabric is sprayed or rolled with a fabric waterproofing agent to form a waterproof layer.
[0044] Coating a waterproof layer on the inner layer of the photonic crystal coated base fabric can ensure that the user does not get wet when used on rainy days, and also improves the durability of the invisibility cloak.
[0045] As a possible implementation manner, the fabric waterproof agent includes at least one of a silicone fabric waterproof agent, an acrylic fabric waterproof agent, a polyurethane fabric waterproof agent, and a fluorocarbon fabric waterproof agent.
[0046] As a possible implementation method, a flame retardant layer is also arranged between the base fabric and the waterproof layer; the flame retardant layer is formed by cross-linking the base fabric of the infrared stealth fabric with a phosphorus silicon-based nano flame retardant by a plasma induction method; or, the flame retardant layer is formed by alternately depositing graphene and casein on the base fabric of the infrared stealth fabric.
[0047] The invisible cloak provided by the utility model has the advantages of being waterproof and fireproof, can better protect the health and safety of users, and has higher reliability and safety.
[0048] See also Figure 1 As a possible implementation method, the invisible cloak also includes: multiple groups of three-dimensional bionic layers 12 sewn on the outer surfaces of the cloak body 10 and the hat 11; the three-dimensional bionic layers 12 adjacent to each other overlap from head to tail; the material of the three-dimensional bionic layers 12 is the same as that of the cloak body 10 and the hat 11.
[0049] As an example, a three-dimensional bionic layer is set on the part above the waist of the hat and cloak. Compared with the traditional flat camouflage, the three-dimensional bionic layer has a high degree of integration with the concealed background and can make full use of the visual habits of the human eye to improve the stealth effect.
[0050] As a possible implementation manner, the three-dimensional bionic layer is at least one of a bionic strip, a bionic grass or a bionic leaf.
[0051] As an example, the three-dimensional bionic layer adopts a bionic strip structure, or the three-dimensional bionic layer adopts a bionic grass structure, or the three-dimensional bionic layer adopts a bionic leaf structure, or the three-dimensional bionic layer adopts a combined structure of bionic strips and bionic grass, or the three-dimensional bionic layer adopts a combined structure of bionic strips and bionic leaves, or the three-dimensional bionic layer adopts a combined structure of bionic grass and bionic leaves, or the three-dimensional bionic layer adopts a combined structure of bionic strips, bionic grass and bionic leaves.
[0052] In actual application, bionic strips, bionic grass or bionic leaves can be flexibly increased or decreased using Velcro according to the actual background environment, which can ensure consistency with the background environment to a greater extent.
[0053] See also Figure 1 As a possible implementation method, the invisible cloak adopts a one-piece pullover design and a pullover door tube design; buttons 13 and air holes are arranged on the side.
[0054] The one-piece pullover design and pullover opening tube design make it easy to put on and take off. Snap buttons are set on the side to facilitate the fixing of the front and back pieces of the cloak. Since the armpit area of the human body is prone to sweating, air holes are set on the side to facilitate the heat dissipation of the human body, which can meet the use requirements in hot environments.
[0055] See also Figure 1 As a possible implementation, an elastic cord 14 for adjusting the size of the hat opening is provided at the brim of the hat.
[0056] The elastic cord makes it easy to adjust the size of the hat opening, so that the hat can better fit the curve of the human head, improving the user's comfort and stealth effect.
