Abstract
Description
Technical Field
[0001] This utility model belongs to the field of protective equipment, and specifically relates to a flame-retardant explosion-proof protective armor device. Background Technology
[0002] Blast-resistant armor is a wearable protective gear designed for high-risk explosion scenarios. Its core function is to protect critical areas such as the chest and back. It achieves protection through a layered composite structure. However, existing blast-resistant armor systems have significant shortcomings in thermal protection during explosions. They struggle to provide effective protection against the high-temperature radiation and contact with localized combustible media accompanying explosions, potentially leading to thermal damage to the wearer's skin. Furthermore, high temperatures can cause performance degradation in the armor materials, affecting the stability of the blast-resistant structure. These problems stem from the fact that the design prioritizes core impact protection needs such as shock wave dispersion and debris containment, while insufficiently considering risks such as heat conduction and combustion spread arising from the explosion. The structure lacks a targeted thermal protection design, and material selection does not prioritize enhanced thermal stability and thermal barrier performance. Conventional solutions often involve having users wear additional thermal protective clothing or accessories to supplement thermal risk protection. However, this approach increases the overall weight and complexity of the garment, restricts limb flexibility, and creates gaps between the extra clothing and the protective armor, making it difficult to completely block the heat conduction path. Furthermore, dedicated thermal protective clothing has high maintenance costs, and its protective performance tends to decline after repeated use, failing to form an integrated protective synergy with the protective armor. Therefore, it is difficult to fundamentally solve the problem of insufficient thermal risk protection. Thus, a new structure is needed to address the aforementioned technical issues.

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flame-retardant explosion-proof armor device to solve the problems mentioned in the background art.
[0004] This utility model is achieved through the following technical solution: a flame-retardant explosion-proof protective armor device, comprising: an inner liner assembly and an armor assembly, wherein the outer surface of the inner liner assembly is fitted with an armor assembly for protection, and the inner liner assembly is fitted with an isolation assembly for isolation, wherein two sets of isolation assemblies are provided, and the two sets of isolation assemblies have the same structure, the inner liner assembly includes an inner liner body, the outer surface of the inner liner body is fitted with a protective armor assembly, the armor assembly includes an armor body, and the outer surface of the armor body is fitted with a memory spring for rebound.
[0005] In a preferred embodiment, the inner lining body has a vest structure, a carrying strap for gripping is installed on the outer surface of the inner lining body, a reflective sticker for warning is installed on the front and rear surfaces of the inner lining body, and a flame-retardant layer is installed inside the inner lining body.
[0006] In a preferred embodiment, the inner lining body is integrally molded from high-strength fiber-reinforced composite material. The structure of the flame-retardant layer matches the structure of the inner lining body. The flame-retardant layer is composed of multiple flame-retardant ceramic sheets. An armor body is installed on the lower side of the outer surface of the inner lining body. In use, when facing the risk of explosion, the memory fragments on the outer side of the armor body can first weaken the direct impact threat of high-speed flying objects through the rebound effect. At the same time, it can efficiently absorb and disperse the energy of the explosion shock wave by its own deformation, avoiding local stress concentration that could cause hard injury to the human body.
[0007] In a preferred embodiment, the armor body is attached to the outer surface of the inner lining body by Velcro. The thickness of the armor body is greater than the thickness of the inner lining body. Multiple memory spring clips are evenly installed on the front and rear sides of the outer surface of the armor body, and the multiple memory spring clips have the same structure.
[0008] In a preferred embodiment, the armor body has multiple layers of composite steel plates inside, and the outer surface of the armor body is wrapped with flame-retardant sponge. The armor body consists of two pieces, and the left and right surfaces of the two armor bodies are fixed by Velcro fasteners.
[0009] In a preferred embodiment, an isolation component is installed on the front inner wall and the rear inner wall of the lining body, respectively. The isolation component includes an isolation plate and a fiberboard. The isolation plate is installed on the rear surface of the fiberboard, and a cushioning rubber is provided on the side surface of the isolation plate away from the fiberboard.
[0010] In a preferred embodiment, the isolation plate is made of heat-insulating material, and the fiberboard is made of carbon fiber. The thickness of the fiberboard is greater than that of the isolation plate. In use, the isolation plate can effectively block the high temperature generated by the explosion from being conducted to the human body, avoiding the risk of high temperature burns from the source of the inner lining layer. It forms a synergistic heat insulation barrier with the flame-retardant function of the armor components. The fiberboard can provide secondary buffering and blocking of residual shock waves and splashes that penetrate the outer armor, further reducing the threat of injury.
[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up the armor component, the outer surface of the inner lining component is equipped with the armor component for protection. The armor component includes the armor body, and the outer surface of the armor body is equipped with a memory shrapnel for rebound. When in use, when facing the risk of explosion, the memory shrapnel on the outer side of the armor body can first weaken the direct impact threat of high-speed flying objects through the rebound effect, and at the same time, it can efficiently absorb and disperse the energy of the explosion shock wave by its own deformation, avoiding local stress concentration that causes hard injury to the human body.
[0012] 2. By setting up an inner lining component, an isolation component is installed inside the inner lining component for isolation. There are two sets of isolation components, and the two sets of isolation components are identical in structure. The isolation components include an isolation plate for isolating temperature and a fiberboard for secondary protection. In use, the isolation plate can effectively block the high temperature generated by the explosion from being conducted to the human body, avoiding the risk of high temperature burns from the source of the inner lining layer. It forms a synergistic heat insulation barrier with the flame-retardant function of the armor component. The fiberboard can provide secondary buffering and blocking of residual shock waves and splashes that penetrate the outer armor, further reducing the threat of injury. Attached Figure Description

A carrying strap 110 for gripping is installed on the outer surface of the inner lining body 100. A reflective sticker 120 for warning is installed on the front and rear surfaces of the inner lining body 100 respectively. A flame-retardant layer 130 is installed inside the inner lining body 100.

The structure of the flame-retardant layer 130 is matched with the structure of the inner lining body 100. The flame-retardant layer 130 is made of multiple flame-retardant ceramic sheets. The armor body 210 is installed on the lower side of the outer surface of the inner lining body 100. The armor body 210 is attached to the outer surface of the inner lining body 100 by Velcro. The thickness of the armor body 210 is greater than that of the inner lining body 100.

At this time, together with the inner lining body 100, it can achieve a good anti-explosion effect. At the same time, the flame-retardant layer 130 of the inner lining body 100 can prevent the combustion from spreading further to the user.
