Description

Technical Field

[0001] This utility model mainly relates to the technical field of transparent armor manufacturing, specifically a one-piece molded external transparent armor assembly. Background Technology

[0002] Transparent armor is a combination of materials that can provide protection while maintaining high transparency. It is mainly used in military and security fields. The manufacturing process of various transparent protective assembly modules, such as bulletproof and explosion-proof, is complicated and involves dozens of processes. Taking the transparent protective window assembly module for vehicles and ships as an example, it is necessary to manufacture two components at the same time: transparent armor (also known as "bulletproof glass") and matching frame. Then, these two components are sealed together with sealant to form a transparent protective assembly module.

[0003] The assembly of the transparent armor and its supporting frame involves numerous complex processes, including primer treatment, protective film installation, and sealant injection. This not only consumes significant manpower and auxiliary materials, but the strong organic solvents in the primer can corrode the organic materials (such as polycarbonate) in the transparent armor, leading to reduced toughness, cracking, and performance degradation. Furthermore, the incompatibility between the sealant and the hot melt adhesive in the intermediate layer of the transparent armor weakens the bond strength, causing the transparent armor to delaminate and significantly reducing its service life. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model mainly provides a one-piece molded external transparent armor assembly to solve the technical problem mentioned in the background art: the sheet-like hot melt adhesive between transparent materials and the sealant between bulletproof glass and the frame are different and incompatible, and the organic solvents in the sealant can easily damage the bonding strength of the hot melt adhesive.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A one-piece molded external transparent armor assembly includes a transparent armor module. The transparent armor module includes an outer frame. Multiple inorganic transparent material layers are disposed within the outer frame, as well as interlayer adhesive material layers on the inorganic transparent material layers. The interlayer adhesive material layers include a first interlayer adhesive layer, a second interlayer adhesive layer, and a third interlayer adhesive layer distributed sequentially from top to bottom. Each granular layer is located on the upper side of the corresponding inorganic transparent material layer, and an outer adhesive material layer is disposed between the layer body composed of multiple inorganic transparent material layers and the inner wall of the outer frame.

[0007] Furthermore, an anti-splash material layer is provided on the upper side of the first interlayer adhesive layer.

[0008] Furthermore, a sealing ring is provided on the lower side of the bottom inorganic transparent material layer, and the sealing ring is pressed against the folded edge of the outer frame to seal.

[0009] Furthermore, the second and third interlayer adhesive layers have the same thickness, both being 1mm-2mm.

[0010] Furthermore, the thickness of the first interlayer adhesive layer is 2mm-3mm.

[0011] Furthermore, the thickness of the outer adhesive material layer is 2mm-3mm.

[0012] Furthermore, the thickness of the anti-splash material layer is 3mm-8mm.

[0013] Furthermore, the thickness of the sealing ring is 3mm-4mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through its outer frame, inorganic transparent material layer, first interlayer adhesive layer, second interlayer adhesive layer, third interlayer adhesive layer, outer adhesive material layer, anti-splash material layer, and sealing ring, achieves the solidification of each material layer and the sides of each material layer with the outer frame into a single unit under the temperature and pressure provided by the pressure vessel door. This achieves a one-time molding process, eliminating the need for sealant and preventing the organic solvents in the sealant from damaging the hot melt adhesive. It also simplifies the assembly steps of the transparent armor assembly, improves work efficiency, and the external installation method offers better installation flexibility, ease of maintenance and replacement, cost advantages, and flexibility for protection upgrades.

[0024] Please refer to the appendix carefully. Figure 1-3 A one-piece molded external transparent armor assembly includes a one-piece molded transparent armor module 1 and an outer frame 11. The transparent armor module 1 is embedded within the outer frame 11. The transparent armor module 1 includes a laminated structure formed by stacking at least one layer of inorganic transparent material 12 and one layer of anti-splash material 14, with an interlayer bonding material layer 13 arranged between adjacent material layers. The outer frame 11 covers the outer periphery of the transparent armor module 1. The anti-splash material layer 14 is located on the outermost side of the outer frame 11, and an outer bonding material layer 134 is provided in the gap between the outer frame 11 and the transparent armor module 1. External installation refers to installing the transparent armor assembly on the outside of the observation window or porthole through a specific connection method, rather than integrating it into its internal structure. It does not require large-scale modifications to the original structure of the vehicle or spacecraft, can be directly added to existing equipment, and can be easily disassembled and replaced when the transparent armor is damaged or needs to be upgraded.

[0025] The above structure enables the materials to solidify into a single unit after being processed by the pressure vessel door, with each layer of material solidifying together with the sides of each layer and the outer frame 11, achieving a one-time molding process. This eliminates the need for sealant, preventing the organic solvents in the sealant from damaging the hot melt adhesive. It also simplifies the assembly steps of the transparent armor assembly, improves work efficiency, and the external installation method offers better installation flexibility, ease of maintenance and replacement, cost advantages, and flexibility in protection upgrades.

[0026] Please refer to the appendix carefully. Figure 2 and attached Figure 3 The interlayer bonding material layer 13 between the inorganic transparent material layer 12 and the anti-splash material layer 14 is made of polyurethane. The interlayer bonding material layer 13 between adjacent inorganic transparent material layers 12 and the outer bonding material layer 134 are made of any hot melt adhesive material. The polyurethane material and hot melt adhesive material are in forms including but not limited to sheet, film, and granular. The anti-splash material layer 14 is made of polycarbonate sheet or organic material with anti-splash properties other than polycarbonate sheet. And / or, the thickness of the anti-splash material layer 14 is 1mm-10mm. Polyurethane material has excellent impact resistance. When subjected to external impact, such as shock waves from an explosion or impact from an object, polyurethane material can absorb and disperse energy. In the case of glass breakage, polyurethane material can adhere broken glass fragments to its surface. Its own toughness makes it difficult for fragments to penetrate, thus effectively preventing glass fragments from flying everywhere like bullets and causing secondary damage to surrounding people and objects. The inorganic transparent material is selected from at least one of the following:

[0027] (a) Glass materials, including but not limited to soda-lime silica glass, borosilicate glass, aluminosilicate glass, lithium aluminosilicate glass or tempered glass;

[0028] (b) Non-glass inorganic materials, including but not limited to sapphire, aluminum oxynitride or magnesium aluminum spinel.

[0029] The interlayer bonding material layer 13 includes a first interlayer bonding layer 131, a second interlayer bonding layer 132, and a third interlayer bonding layer 133 arranged sequentially from the outside to the inside. The first interlayer bonding layer 131 and the second interlayer bonding layer 132 have the same thickness, both being 0.3mm-3mm; and / or, the thickness of the third interlayer bonding layer 133 is 0.3mm-4mm. The outer bonding material layer 134 has a thickness of 1mm-5mm. The polyurethane granules used in the outer bonding material layer 134 not only provide thermal insulation but also have good sealing performance. They can fill gaps and holes in the building structure to prevent air leakage. A sealing ring 15 is provided at the folded edge of the outer frame 11, and the innermost inorganic transparent material layer 12 presses the sealing ring 15 against the folded edge of the outer frame 11 to achieve a seal. The sealing ring 15 has a thickness of 3mm-5mm. Through the sealing ring 15, the gaps are sealed, preventing dust particles from entering.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
