Description

Technical Field

[0001] The utility model belongs to the technical field of stealth bionics, and in particular relates to a stealth suit. 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 infrared stealth suits currently used are difficult to meet the needs of practical applications, mainly in the following aspects:

[0004] (I) Traditional stealth suits have poor stealth effects against thermal targets. The materials used to make stealth suits in the prior art are generally low-emissivity materials, and the infrared emissivity of 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 suits are not good enough to resist optical reconnaissance. Since they only use camouflage colors, the stealth methods are not rich enough and the integration with the background is not good enough, the optical stealth effect is poor.

[0007] (IV) The wearing and taking off process of the stealth suit provided by the prior art is similar to that of ordinary clothing, and there is a problem of inconvenience in wearing and taking off. Utility Model Content

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] In a first aspect, the utility model provides a stealth suit, characterized in that it comprises a stealth hood, a stealth top, stealth pants and stealth shoe covers; the stealth suit is made by cutting and sewing infrared stealth fabric; the infrared stealth fabric is made of photonic crystal coated base fabric.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Most of the currently widely used stealth suits are made of low-emissivity materials, which have the disadvantages of low thermal radiation suppression ability and difficulty in heat dissipation. In addition, the stealth effect and wearing and removing process of traditional stealth suits have great limitations, which are difficult to meet the needs of practical applications. In order to solve the above problems, the utility model provides a stealth suit that takes into account infrared stealth and breathable heat dissipation, and has the advantages of being easy to wear and take off.

[0041] See also Figure 1 The stealth suit provided by the utility model comprises a stealth head cover 1, a stealth top 2, stealth pants 3 and stealth shoe covers 4; the stealth suit is made by cutting and sewing infrared stealth fabric; the infrared stealth fabric is made of photonic crystal coated base fabric.

[0042] The stealth suit provided by the utility model comprises a stealth head cover, a stealth coat, stealth pants and stealth shoe covers, which can achieve full-body shielding and greatly improve the stealth effect.

[0043] The infrared stealth fabric used to make stealth suits uses photonic crystal coated base fabric. Due to the bandgap characteristics of photonic crystals, the required low emissivity can be achieved in a specific band. Theoretically, the emissivity can be lower than 0.05, and in practice it is lower than 0.2. After considering the compatibility with visible light, it is still lower than 0.5, 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 suit.

[0044] 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 bands outside the atmospheric windows, thereby avoiding the problem of heat accumulation of hot targets.

[0045] The utility model is basically made of photonic crystal coating. 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 higher breaking force and tearing force, and is easy to carry.

[0046] See also Figure 2 As a possible implementation method, the invisible top 2 includes a body 20, sleeves 21, fasteners 22, a strip net and multiple groups of three-dimensional bionic layers; wherein the strip net is sewn on the outer surfaces of the body 20 and the sleeves 21; multiple groups of three-dimensional bionic layers are sewn from top to bottom on the strip net located on the outer surfaces of the body 20 and the sleeves 21; the upper and lower adjacent three-dimensional bionic layers overlap head to tail; the fasteners 22 are used to fasten the front lapels of the body.

[0047] Compared with 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. The strip net is sewn on the outer surface of the body and sleeves. On the one hand, it can reinforce the stealth suit and improve its tear resistance; on the other hand, it can facilitate the hanging and placement of the stealth suit after use. In actual application, branches, leaves, grass, etc. in the background environment can be inserted into the strip net to further improve the stealth ability.

[0048] As an example of a fastener, the fastener can be a buckle, Velcro, snap button, etc., which can enhance the firmness of the stealth suit when worn on the human body on the one hand, and facilitate the wearing and taking off of the stealth suit on the other hand.

[0049] As a possible implementation manner, the invisible hood and the invisible top are an integrated structure, or the invisible hood and the invisible top are a split structure.

[0050] The invisible hood and invisible top can adopt an integrated structure or a split structure. The integrated structure is convenient for carrying and putting on and taking off, while the split structure allows the wearer to choose to wear the invisible hood or the invisible top separately according to actual application needs, which has high flexibility.

[0051] As a possible implementation method, the invisible pants are invisible pants with multiple groups of three-dimensional bionic layers sewn on the outer surface; the multiple groups of three-dimensional bionic layers are sewn on the outer surface from top to bottom; the upper and lower adjacent three-dimensional bionic layers overlap head to tail; the three-dimensional bionic layer is at least one of bionic strips, bionic grass or bionic leaves.

[0053] The invisible suit, invisible top, invisible pants, invisible head cover and invisible shoe covers provided by the utility model are all based on camouflage color, and bionic strips, bionic grass or bionic leaves similar to the background environment are used as three-dimensional bionic layers sewn on the invisible top, invisible pants, invisible head cover and invisible shoe covers, which can make full use of the visual habits of human eyes to improve the stealth effect.

[0054] 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.

[0055] In actual application, the bionic strips, bionic grass and 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.

[0056] See also Figure 3 As a possible implementation method, the waistband 30 of the invisible pants 3 is made of elastic band, which makes it easier to put on and take off the invisible pants; the crotch 31 of the invisible pants 3 is processed by adding triangles, which can increase the activity of the legs while enhancing the tension and firmness;

[0057] See also Figure 3 As a possible implementation method, the trouser legs 32 of the invisible pants 3 adopt a high-slit, buckled design. The buckling method can be Velcro, snaps or buckles, which is convenient for wearing and taking off. The size of the trouser legs can also be freely adjusted according to needs. It is also convenient to combine with invisible shoe covers to improve the stealth effect.

[0058] See also Figure 4 As an example, the invisible headgear 1 also includes a face shield 10. The face shield 10 is an independent component, and the bridge of the nose is designed with a three-dimensional structure, which fits the user's face better and is more comfortable. The face shield 10 is sewn and fixed to the side piece of the invisible headgear on one side, and the other side is bonded with Velcro, which is convenient for wearing and removing, and also convenient for different users to adjust the size. The neck size is designed with a strap and Velcro, which is convenient for different users to adjust and more convenient for wearing and taking off.

[0059] See also Figure 4 The bottom edge of the invisible hood is curved and then sewn, which is more in line with the shape of the human neck, so that the wearer's head movement is not restricted. The brim of the invisible hood is polished, which is more comfortable to touch the skin. The middle seam of the hat is tightly locked to increase the firmness. The strap is designed with narrow straps, double-layer fabrics, and polished and sewn all around, which is convenient for buckling and closing, and enhances concealment.

[0060] See also Figure 5 As an example, the stealth shoe cover 4 adopts a three-dimensional, open-bottom design according to the needs of concealment, running and other tasks, which can completely cover the entire shoe surface. The front section adopts a rolled edge and I-shaped pleat process, which can firmly hook the shoe head; an elastic strap is designed at the heel depression, and the connection with the foot opening adopts a rear-opening, integral strap through the horse king strap and Velcro design, which can be adhered and tied, and is easy to put on and take off and is stable.

[0061] As a possible implementation method, heat dissipation holes are provided on the invisible head cover, invisible top, invisible pants and invisible shoe covers.

[0062] As a possible implementation manner, the density of the heat dissipation holes opened at the armpits, chest and back of the invisible top is greater than the density of the heat dissipation holes opened at other positions.

[0063] Taking into account the use in hot environments, heat dissipation holes are opened on the invisible hood, invisible top, invisible pants and invisible shoe covers. Further calculation and analysis are carried out based on the body temperature and sweat gland distribution of various parts of the human body. The armpits, chest and back of the human body are prone to sweating. Therefore, the density of heat dissipation holes opened in the armpits, chest and back of the invisible top is greater than the density of heat dissipation holes opened in other positions, which maximizes the heat dissipation needs of the user in a hot environment.

[0064] In actual application, the invisible suit provided by the utility model can be designed and manufactured in different sizes, which can ensure that users of different heights and body shapes can wear it more comfortably and move more conveniently and flexibly. The invisible shoe covers and invisible head covers adopt a three-piece structure, which is more in line with the head and foot shapes and activity requirements of different users.

[0065] The lower surface of the infrared stealth fabric used in the stealth suit provided by the utility model is also provided with a flame retardant material layer.

[0066] As an example, the flame retardant material layer is a flame retardant material layer 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. It needs to be further explained that the phosphorus silicon-based nano flame retardant is prepared by reacting vinyl phosphate and tetramethyl divinyl disiloxane by a one-step free radical polymerization method. With this arrangement, the peak heat release rate and total heat release of the flame retardant material layer are reduced by 47.3% and 29.8% respectively, and the oxygen index is increased to 27%. It has good cycle washability, and the introduced phosphorus silicon-based nano flame retardant has little effect on the mechanical properties and comfort of the infrared stealth fabric.

[0067] As a second example, the flame retardant material layer is formed by alternately depositing graphene and casein on the base fabric of the infrared stealth fabric. In this way, the oxygen index of the flame retardant material layer is increased to 23.6%. The surface resistance reaches 4.974×10 4Ω, has good flame retardant and antistatic properties.
