Description

Technical Field

[0001] This invention relates to a modular cabin panel, belonging to the field of modular cabins. Background Technology

[0002] The invention of gunpowder ushered in the era of firearms, leading to the continuous development of various guns and cannons. To withstand the damage from gunfire, people have constantly invented various protective methods and equipment. Furthermore, the protective capabilities of various types of modular shelters widely used in battlefield environments have been subject to even more stringent requirements.

[0003] As the core component of the shelter, the main plate directly determines the overall strength and rigidity of the shelter. Currently, there are two common types of bulletproof shelter main plates on the market: one type achieves bulletproof protection by covering the outside of the main plate, and the other type achieves bulletproof protection by bonding non-metallic bulletproof plates to the inside of the main plate to form a whole.

[0004] The method of covering the large plate with bulletproof plates fails to form an integral structure between the bulletproof plates and the plate, making the interface between the two materials prone to corrosion. Moreover, the screw-on covering method requires drilling holes in the large plate, which not only compromises the integrity of the container but also adversely affects its airtightness and electromagnetic shielding performance.

[0005] The method of bonding bulletproof plates to the interior of a large panel can only be used with non-metallic, lightweight bulletproof materials. Furthermore, this single-layer bonding method severely limits the thickness of the bulletproof plates, making it unsuitable for container cabins with higher bulletproof requirements. Additionally, these non-metallic bulletproof plates are expensive, making cost control difficult. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a bulletproof cabin panel that can improve the bulletproof performance of the cabin by adding bulletproof materials inside the cabin panel without compromising the cabin's airtightness.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a bulletproof container panel, comprising a steel frame, inner and outer skins, a bulletproof layer and a filling layer.

[0008] The steel frame is made of steel pipes forming several connected rectangular frames; the bulletproof layer is an open-top cuboid structure, with the closed end installed inside the rectangular frame of the steel frame and the open end edge folded outwards and overlapped on the rectangular frame of the steel frame; the filling layer is made of lightweight material and is filled in the open-top cuboid cavity of the bulletproof layer; the steel frame, bulletproof layer and filling layer are sealed between the inner and outer skins.

[0009] The inner and outer skins are made of aluminum plates with a thickness of 0.8 to 2 mm.

[0010] The steel frame is constructed by welding square steel tubing.

[0011] The bulletproof layer is made of bulletproof steel plate or composite bulletproof plate.

[0012] The filling layer is made of high-density polyurethane foam board or honeycomb core board.

[0013] The inner and outer skins and the steel frame, the steel frame and the bulletproof layer, and the bulletproof layer and the inner and outer skins are all bonded together using thermosetting resin and curing agent.

[0014] The bulletproof layer and the steel frame are riveted together by drilling.

[0015] The beneficial effects of this invention are:

[0016] 1) This invention provides a solution for manufacturing bulletproof container panels by adding a bulletproof layer inside the container panel, which can both efficiently avoid damaging the container's airtightness and firmly fix the bulletproof material.

[0017] 2) By embedding a bulletproof layer inside the bulkhead panel, this invention effectively avoids the crack defects and structural damage problems of the bulkhead panel that cannot be avoided by conventionally welding / screwing bulletproof plates on the outer surface of the bulkhead panel, thus enabling the bulkhead to have both excellent bulletproof capability and excellent sealing performance.

[0018] 3) The present invention adopts modular inlay of bulletproof plates, which effectively suppresses the aggravation of cracks and defects caused by bullet shooting, limits the damage to a local area, and greatly reduces the later maintenance costs. Attached Figure Description
