Magnetic-suction armor structure, magnetic-suction-type ceramic composite armor and vehicle

Abstract

The invention provides a magnetic-suction armor structure, a magnetic-suction-type ceramic composite armor and vehicle. The magnetic-suction armor structure is used for being mounted on a vehicle bodyof the vehicle and comprises a high-intensity magnetic unit, a magnetic shielding unit, and an elastic material layer, wherein the high-intensity magnetic unit forms a flake structure and used for being sucked onto the vehicle body through the magnetic force; the magnetic shielding unit is connected to one side of the high-intensity magnetic unit and used for shielding the magnetic field on the outer side of the vehicle body; and the elastic material layer is wrapped on the outer periphery of the high-intensity magnetic unit and the magnetic shielding unit. The magnetic-suction armor structure is simple in structure and convenient to install and detach, drilling on a steel plate of a vehicle substrate can be avoided so that the vehicle bearing capacity and hanging armor manufacturing accuracy are reduced, the capacity to resist multiple projectiles is improved, the protecting effect is high, and the lightweight requirements can be met.

Description

Technical field [0001] The present invention relates to the technical field of automobile manufacturing, in particular to a magnetically attracted armor structure, a magnetically attracted ceramic composite armor and a vehicle. Background technique [0002] With the requirements of combat, anti-terrorism, and riot prevention under the new situation, the protection level of protective vehicles is getting higher and higher. Relying on increasing the thickness of the protective steel plate alone will cause the weight of the vehicle to rise sharply, and the dynamic performance of the vehicle will decline, which is difficult to meet the tactical needs. The manufacturing difficulty will also be greatly increased. Therefore, most of the development of new protective vehicles at home and abroad directly adopts the method of composite draping armor, or adopts the method of draping armor to protect and upgrade existing vehicles. The draping armor mostly uses light weight such as ceramic, c...

AI Technical Summary

Problems solved by technology

The draped armor adopts the steel bolt connection method, which has the advantages of reliable connection, convenient disassembly and assembly, and simple structure, but it is inevitable to open holes in the bulletproof steel plate of the car body. The processing cycle is long, and thermal processing has an adverse effect on the performance of the bulletproof steel plate; on the other hand, the opening of the hole is likely to cause stress concentration in the car body structure and reduce the bearing capacity. The maintenance cost of the whole vehicle increases, and the weight of the steel bolt and nut structure itself is relatively large, which increases the difficulty of lightweight

Moreover, the screw connection method itself has low dynamic load capacity, and it is easy to loosen under the action of alternating loads, and it is prone to connection failure or loss of disassembly ability due to large deformation due to the direct action of bullets.
