Technical Field

The invention relates to the field of vehicles, in particular to a protective armor and a vehicle with the same.

Background

The light protection armored vehicle generally adopts a homogeneous steel armor as a protection base body, and with the improvement of protection grade capability, on one hand, the protection requirement is met by increasing the thickness of a steel plate, but the vehicle body weight is increased sharply, and the maneuvering capability of the vehicle is reduced; on one hand, the light armor is formed by compounding light materials such as ultra-high molecular weight polyethylene, aramid fiber and ceramic with a steel plate, but the multi-shot resistance is reduced, an obvious edge effect exists, the risk of protection failure is increased, and the price is high.

At present, one or more of ceramics, ultrahigh molecular weight polyethylene, aramid fiber, foam materials and the like are mostly adopted for the light armor to be compounded with a steel plate to form a multilayer armor, so that the protection effect is met, and the quality of the whole vehicle is controlled. However, ceramic and foam materials have the characteristic of high brittleness, and are fragile when being impacted by a shot with the caliber of 7.62mm, so that the resistance to multiple shots is weak. When the materials such as the ultra-high molecular weight polyethylene, the aramid fiber and the like are applied, the materials are in a multi-layer pressing state, the layering failure is easy to occur after the impact of the projectile, and the obvious edge effect exists at the edge; meanwhile, the paint has obvious high and low temperature sensitivity, and the protection effect in high-temperature and high-cold areas is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

A protective armor 100 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Protective armor 100 according to an embodiment of the present invention comprises armor back sheet 10, armor core sheet 20, and armor face sheet 30.

In other words, as shown in fig. 1 to 5, the protective armor 100 mainly comprises an armor back plate 10, an armor core plate 20 and an armor face plate 30, that is, the protective armor 100 mainly comprises three layers of protection plates, the three layers of protection plates can be arranged in parallel, the protective armor 100 can protect the impact of a pill 200 with the caliber of 7.62mm with the pill speed of more than 800m/s, the armor face plate 30 is used as a bullet-facing protection plate, and after the pill 200 passes through the armor face plate 30, the bullet-proof holes 21 on the armor core plate 20 change the strike direction of the pill 200, so as to guide the impact direction of the pill 200. The protection principle diagram of the protective armor 100 is shown in fig. 5, the number of the boundaries of the armor core plate 20 is increased by the plurality of armor holes 21, and by utilizing the edge effect caused by a large number of boundaries of the armor core plate 20, when a projectile 200 impacts the protective armor 100, the projectile penetrates through the armor panel 30 and then impacts on the high-hardness armor core plate 20, the projectile 200 deflects to the weak side (i.e. the direction of an inclined round hole) due to the edge effect and then obliquely acts on the armor back plate 10, at the moment, the incident angle is increased, the speed is reduced, and the projectile 200 is difficult to penetrate through the armor back plate 10, so that the effective protection of the armor is.
