Description

Technical Field

[0001] This utility model belongs to the field of armor protection equipment, and specifically relates to a high-ductility, high-weather-resistant and explosion-proof armor protection device. Background Technology

[0002] Blast-resistant armor is a type of protective equipment designed with a multi-layered composite structure to withstand the penetration of explosive shock waves and high-speed fragments, while also being environmentally adaptable. However, existing blast-resistant armor devices are prone to problems such as localized stress concentration, structural delamination, or brittle fracture when subjected to explosive impacts. They struggle to fully dissipate impact kinetic energy and may also carry the risk of secondary fragmentation. Furthermore, long-term outdoor use can lead to cumulative damage from repeated impacts, resulting in a decline in protective performance. These shortcomings stem from insufficient attention to flexible deformation adaptation under impact loads in their design. The limited collaborative deformation capabilities between material combinations and structural layers prevent the gradient transfer and absorption of energy through ordered deformation. Conventional solutions often involve using high-density rigid materials or stacking multiple rigid structures to enhance resistance. However, rigid structures have limited energy absorption thresholds and are ill-suited for dynamic loads under high strain rate impacts. This approach fails to fundamentally solve the stress concentration problem and may increase the structural weight, leading to additional load-bearing burdens. Long-term use can also exacerbate the risk of protective failure due to fatigue damage, making it difficult to balance protective effectiveness with operational flexibility. Therefore, a new structure is needed to address these technical problems. Utility Model Content

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.

[0021] Please see Figures 1 to 4 As the first embodiment of this utility model: a high-ductility, high-weather-resistant, and explosion-proof armor device, comprising: armor component one, armor component two, and armor component three, armor component one, armor component two, and armor component three are fixedly connected by a fixing rod 400, the specifications of armor component one, armor component two, and armor component three are matched, armor component two is installed on the front surface of armor component three, and armor component one is installed on the front surface of armor component two. Armor component one includes armor plate one 100 and elastomer 120, armor component two includes armor plate two 210 and honeycomb plate 230, and armor component three includes armor plate three 300 and extended mesh 320; A mounting hole 110 is provided through the front surface of the guard plate 100. The mounting hole 110 has a square structure. An elastomer 120 is installed on the inner wall of the mounting hole 110. The elastomer 120 is made of amino-terminated polyether polyurea elastomer and polyethylene short fibers. A circular through hole is opened at each of the four corners of the front surface of the first protective plate 100. A barrier 200 is installed on the outer surface of the second protective plate 210. The second protective plate 210 is located at the center of the inner wall of the barrier 200. A honeycomb panel 230 is evenly installed on the surface of the second protective plate 210. Multiple honeycomb panels 230 are provided, and multiple honeycomb panels 230 constitute a honeycomb structure 220. The honeycomb panel 230 is made of carbon fiber plate. The surface of the second protective plate 210 is provided with a second mounting hole 310. The first mounting hole 110 has the same structure as the second mounting hole 310. An extension mesh 320 is installed inside the mounting hole 2 310. The surfaces of the protective plate 2 210 and the protective plate 3 300 are all provided with circular through holes that match the position of the protective plate 1 100. The front and rear surfaces of the protective plate 2 210 are fixed with the protective plate 1 100 and the protective plate 3 300 by the retaining 200 fixing clips. In use, the user first installs armor component one on the front surface of armor component two, and then installs armor component three on the rear surface of armor component two. When fixing armor components three, two, and one, they are secured using the circular through holes and fixing rod 400 on their surfaces. After securing, a weather-resistant jacket made of aliphatic isocyanate is fitted onto the outer surface to increase its service life. Due to the overlapping installation structure of armor components three, two, and one on the front, and with the help of the elastomer 1 in armor component one… The high ductility of the 20 and the initial protective effect of the first protective plate 100, combined with the high efficiency of the blast energy absorption performance of the honeycomb plate 230 in the second protective plate assembly and the structural reinforcement effect of the second protective plate 210, form a multi-layer synergistic protection system. In use, it can not only dissipate the blast impact energy step by step through the deformation of the elastomer 120 and the buffer of the honeycomb plate 230, and block the penetration of high-speed fragments, but also avoid the armor itself from brittle failure by relying on the synergistic effect of the multi-layer protective plates and functional components. At the same time, it can ensure the overall stability of the structure and long-term weather resistance, providing comprehensive, reliable and durable blast protection for the protected object.

[0022] Please see Figures 1 to 4 As a second embodiment of this utility model: based on the description in the above embodiments, further, the first protective plate 100, the second protective plate 210 and the third protective plate 300 are fixedly installed with fixing rods 400 through four circular through holes, and fixing rivets are provided at both ends of the fixing rods 400. The materials of the first protective plate 100, the second protective plate 210 and the third protective plate 300 are all gypsum fiberboard. The specifications of the extended mesh 320 match those of the mounting hole 310. The extended mesh 320 is composed of multiple meshes woven from memory metal. The outer surfaces of armor plates 100, 210, and 300 are fitted with a weather-resistant jacket made of aliphatic isocyanate material. In use, when subjected to an explosive impact through the operation steps of the first embodiment, the elastomer 120 inside the first protective plate 100 and the honeycomb structure 220 inside the second protective plate 210 can intercept and resist blasts. When the impact effect acts on the extended mesh 320 inside the third protective plate 300, the structural rigidity of the third protective plate 300 can achieve initial impact resistance and external environmental protection. Furthermore, the high ductility of the extended mesh 320 allows for flexible deformation under explosive impact. In the initial unimpacted state, the shape memory metal woven extended mesh 320 tightly adheres to the surface of the third protective plate 300. Thanks to the shape stability and weather resistance of the shape memory metal, it adapts to complex outdoor environments such as high and low temperatures and salt spray, maintaining the integrity of the mesh structure and preventing irreversible deformation. Together with the third protective plate 300, it forms the initial protective layer. When encountering an explosive impact, the shock wave or high-speed fragments act on the third protective plate 300. After some energy is initially resisted by the third protective plate 300, the remaining impact force... The impact energy is transferred to the extended mesh 320. Thanks to its excellent ductility, the shape memory metal mesh responds quickly to flexible deformations such as multi-directional stretching and twisting. The woven structure disperses localized stress, preventing single-point overload fracture. Simultaneously, it continuously absorbs and dissipates impact kinetic energy during deformation. After the impact energy is depleted, the shape memory metal, through its shape memory effect, restores its atomic arrangement to its initial stable state, causing the extended mesh 320 to gradually return to its original deformed state and re-attach to the armor plate 300, restoring its initial protective structural form. This ensures continued stable protection. Furthermore, the gap design of the woven mesh helps dissipate heat and residual stress generated by the impact, further enhancing the blast resistance and reusability of the armor component 3. It efficiently dissipates impact kinetic energy, alleviates stress concentration, and prevents brittle fracture of the armor. The combined structure of both enhances the overall stability and weather resistance of the component, effectively blocking high-speed fragment penetration. This creates a reliable protective barrier that combines rigid support with flexible buffering, ensuring stable protective performance during long-term use.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
