[0003] Most of rear walls of cabs of existing motor train units have no ballistic-resistant function. Even if it has the ballistic resistant function, it is only ballistic resistant for pistol bullets. The ballistic-resistant function is weak, and the special safety requirement with respect to a cab of a motor train unit is not fully considered. Moreover, plywood is generally used as the material of the rear wall of the cab of the motor train unit, and the exposed surface is of wood style, so the aesthetic degree needs to be improved.

[0004] Herein, it should be noted that, the technical contents provided in this section are intended to assist understanding of the present application by the person skilled in the art, and do not necessarily constitute the conventional technology. US2010012004A1 discloses basalt particles, when combined with a resin binder and a reinforcing material, such as fiberglass, provide unexpected strength, fire-resistance, radiation impermeability, and projectile shielding for ballistic armor / shields, fire-resistant building panels, construction blocks and protective coatings on substrates. The armor panels can be worn, as in a bullet-proof vest, or can be used as a shield to protect a vehicle, aircraft or other structures as projectile penetration-resistant and fire and radiation resistant materials.SUMMARY

[0005] In view of this, an object of the present application is to provide a ballistic-resistant partition wall of a motor train unit, so as to improve the ballistic-resistant ability of a cab of the motor train unit.

In the drawing: Figure 1 is a schematic sectional view of a ballistic-resistant partition wall of a motor train unit provided according to the present application.DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions of the present application are described with embodiments in the following, but are not limited thereto.

[0016] Referring to Figure 1, Figure 1 a schematic sectional view of a ballistic-resistant partition wall of a motor train unit provided according to the present application.

An inner sound insulation pad 12 and an inner fire-resistant plate 13 are arranged on an inner side of the ballistic-resistant armor plate main body from an inside to an outside, and the outer sound insulation pad 21 is adhered to an outer side of the ballistic-resistant armor plate main body 1. The thickness of the ballistic-resistant armor plate main body 1 is 2.3 to 2.7mm. The ballistic-resistant armor plate main body 1 is built in the ballistic-resistant partition wall, and the thickness of the ballistic-resistant armor plate main body is 2.3 to 2.7mm, thereby ensuring the overall ballistic-resistant ability of the ballistic-resistant partition wall and reducing the weight of the wall. A sound insulation pad is arranged on each of two sides of the ballistic-resistant armor plate main body 1, and the fire-resistant plate 13 is arranged on the inner side of the ballistic-resistant armor plate main body 1, that is, a side close to the cab, so as to ensure the sound insulation ability of the working space.

[0018] In a specific embodiment of the present application, a honeycomb plate is further adhered to the outer side of the outer sound insulation pad 21, and a toughened glass decorative layer 26 is adhered to an outer side of the honeycomb plate. The outer side of the ballistic-resistant armor plate main body 1 is a passenger compartment. A TV and other equipments are generally installed on the ballistic-resistant partition wall. In order to improve the bearing capacity of the ballistic-resistant partition wall, the honeycomb plate is adhered to the outer sound insulation pad to improve the bearing capacity of the ballistic-resistant partition wall, and the toughened glass decorative layer is adhered to the outer side of the honeycomb plate to improve the beauty of the ballistic-resistant partition wall.

[0019] In a specific embodiment of the present application, the honeycomb plate includes a paper honeycomb plate 23 adhered to the outer sound insulation pad 21 and an aluminum honeycomb composite plate 25 arranged on an outer side of the paper honeycomb plate 23. The honeycomb plate includes the inner paper honeycomb plate 23 and the outer aluminum honeycomb composite plate 25. The weight of ballistic-resistant partition wall is reduced by the paper honeycomb plate 23, and the bearing capacity of the ballistic-resistant partition wall is ensured by the aluminum honeycomb composite plate 25.

[0020] In a specific embodiment of the present application, a first prepreg bonding layer 22 is provided between the paper honeycomb plate 23 and the outer sound insulation pad 21, and a second prepreg bonding layer 24 is provided between the paper honeycomb plate 23 and the aluminum honeycomb composite plate 25. Prepreg is a composite of resin matrix and reinforcement by impregnating continuous fiber or fabric with resin matrix under strictly controlled conditions, and is an intermediate material for manufacturing composite materials. The outer sound insulation pad, the paper honeycomb plate and the aluminum honeycomb composite plate are sequentially connected by the first prepreg bonding layer and the second prepreg bonding layer to form an integrated structure, which further ensures the overall strength of the ballistic-resistant partition wall.

[0021] In an embodiment, the thickness of the ballistic-resistant armor plate main body 1 is 2.3 to 2.7mm. More preferably, the thickness of the ballistic-resistant armor plate main body 1 is 2.5mm.

[0023] In a specific embodiment of the present application, the ballistic-resistant armor plate main body 1 is surrounded by a ballistic-resistant armor plate edge in a peripheral direction of the ballistic-resistant armor plate main body 1, and the paper honeycomb plate 23 is surroundingly arranged in the ballistic-resistant armor plate edge.

[0024] The ballistic-resistant armor plate main body 1 of the ballistic-resistant partition wall is arranged close to the inner side. The ballistic-resistant armor plate main body 1 is eccentrically compounded with each layer, that is, the armor plate is not in the middle of the sandwich structure, thus leaving enough space for embedding a TV.

[0025] In order to ensure the overall stability of the ballistic-resistant partition wall after the ballistic-resistant armor plate main body is eccentrically compounded. The periphery of the ballistic-resistant armor plate is surrounded by the ballistic-resistant armor plate edge, and the paper honeycomb core material is filled in an "armor basin" that its periphery is surrounded. At the same time, the problem of connection and fixation between a wall and a vehicle body is solved.

[0026] According to the ballistic-resistant partition wall provided by the present embodiment, the ballistic-resistant performance meets the grade B protection requirements of the technical conditions for protection of special cash carriers (GA164-2005), which can effectively protect the shooting of 79 submachine guns with steel core bullets, and improve the safety level of the cab of the motor train unit.
