Description

Technical Field

[0001] The invention relates to a top protection module of an armored vehicle for defending against attacks by unmanned aerial vehicles, and particularly belongs to the technical field of armor protection. Background Art

[0002] Armor protection technology is a technology that has gradually developed with the development of anti-armor ammunition technology. It integrates materials, structures and advanced manufacturing technologies. It is the basis of armored vehicles' battlefield survivability. It is currently developing in the direction of multi-function, lightweight and intelligent.

[0003] Armored steel has good toughness and high hardness, but high density. Simply increasing the thickness of armored steel to achieve protection is not conducive to the lightweight and high mobility of vehicles. Foamed aluminum has low density, light weight, high specific strength, good energy absorption and buffering, shock absorption and other physical and mechanical properties, and is particularly suitable for service environments subjected to extreme loads such as explosion impact. However, due to its low strength, foamed aluminum is generally used as a filling core layer in the "sandwich" structure, acting as an energy absorption layer for large deformation of the structure under the strong dynamic load of explosion impact. As a superelastic polymer material, polyurea has super strong tensile strength. It is not only easy to spray and cure quickly, but also has strong adhesion to substrates including metals and non-metals, which can ensure long-term coating without falling off. It has the excellent characteristics of reducing the cracking, collapse and deformation of the structure under the strong dynamic load of explosion impact, which can further improve the protective performance of the structure. Therefore, combining the respective material properties of armored steel, foamed aluminum and polyurea, a sandwich structure protection module for the top of an armored vehicle that can defend against drone attacks is proposed, which is of great significance in the field of armor protection technology. Summary of the invention

[0004] The purpose of the present invention is to provide an armored vehicle top protection module for defending against drone attacks, so as to ensure that the ability of the armored vehicle to defend against drone attacks from the top can be effectively improved without significantly increasing the weight of the armored vehicle.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: the invention includes a protection module and an armored vehicle roof, and also includes a steel beam;

[0006] The protection module includes an external hard polyurea layer, a perforated armor steel, a foam aluminum layer and an internal soft polyurea layer. A steel beam is arranged under the protection module. Both the protection module and the steel beam are provided with connecting bolt holes. Bolts are connected in the connecting bolt holes. The protection module is connected to the steel beam through bolts.

[0007] An armored vehicle roof is arranged below the protection module and the steel beam, a threaded bolt hole is arranged in the armored vehicle roof, and the protection module is connected to the armored vehicle roof through bolts and the threaded bolt holes;

[0008] The outer hard polyurea layer and the inner soft polyurea layer are both sprayed elastomeric polyurea materials. The outer hard polyurea layer is sprayed on the surface of the perforated armor steel, and the inner soft polyurea layer is sprayed on the surface of the foam aluminum layer.

[0009] The foam aluminum layer adopts a density between 200kg / m 3 -1000kg / m 3 The closed-cell foam aluminum, the perforated armor steel and the foam aluminum core layer are bonded with resin glue;

[0010] The thickness of the external hard polyurea layer and the internal soft polyurea layer sprayed is not less than 5mm, and the surface density of the protection module is less than or equal to 40kg / m 2 , the thickness of the protection module is less than or equal to 20mm;

[0011] Furthermore, the outer hard polyurea layer and the inner soft polyurea layer can be prepared by adjusting the proportion of material components, the overall hardness of the protection module is improved by the perforated armor steel, and the explosion shock wave is introduced into the foam aluminum layer, which then absorbs energy and buffers it.

[0012] The perforated armor steel is made of armor steel, aluminum alloy and titanium alloy. The perforated armor steel is provided with circular holes with a diameter of 7mm-10mm at equal intervals.

[0013] Furthermore, the openings are provided for the perforated armor steel to reduce its own weight.

[0014] The beneficial effects of the present invention are:

[0015] 1. Through the structural setting of the protection module, the protection module can enhance the armored vehicle's ability to defend against drone attacks without significantly increasing the weight of the armored vehicle, and can effectively protect the vehicle from damage by drone bullets and explosives.

[0016] 2. Through the structural setting in which the protection module, the steel beam and the armored vehicle roof are connected by bolts, the protection module can be installed on the armored vehicle roof in wartime and can be disassembled in peacetime, which is easy to load and unload, replace and carry.

[0021] The following will be combined with the attached Figure 1-3 , clearly and completely describe the technical solutions in the embodiments.

[0022] Specific implementation method 1: Figure 1 As shown, the overall structure consists of a protection module 5, a steel beam 9 and an armored vehicle roof 7. The protection module 5 includes an external hard polyurea layer 1, a perforated armor steel 2, a foamed aluminum layer 3 and an internal soft polyurea layer 4, wherein the external hard polyurea layer 1 and the internal soft polyurea layer 4 are both sprayed elastomeric polyurea materials, the external hard polyurea layer 1 is sprayed on the surface of the perforated armor steel 2, the internal soft polyurea layer 4 is sprayed on the surface of the foamed aluminum layer 3, and the perforated armor steel 2 and the foamed aluminum core layer 3 are bonded with resin glue, so the protection module 5 is sequentially composed of an external hard polyurea layer 1, a perforated armor steel 2, a foamed aluminum layer 3 and an internal soft polyurea layer 4 from top to bottom.

[0023] Specific implementation method 2: Figure 2-3 As shown, there are two methods for installing the protection module 5 and the armored vehicle roof 7. One is to directly install the protection module 5 to the armored vehicle roof 7; the other is to first connect the steel beam 9 with the rigid spring to the armored vehicle roof 7, and then connect the protection module 5 to the steel beam 9;

[0024] Since the protection module 5 and the steel beam 9 are both provided with connection bolt holes, the armored vehicle roof 7 is provided with threaded bolt holes 8, and the two sets of connection bolt holes and the threaded bolt holes 8 are both threadedly connected with bolts 6, the steel beam 9 can be installed to the armored vehicle roof 7 through the bolts 6, and the protection module 5 can be installed to the top surface of the steel beam 9 through the bolts 6, so that the protection module 5 and the armored vehicle roof 7 are connected as a whole, and the protection module 5 can protect the armored vehicle roof 7;

[0025] By arranging that the protection module 5, the steel beam 9 and the armored vehicle roof 7 can be installed by bolts 6, the protection module 5 can be installed on the armored vehicle roof 7 in wartime, and the protection module 5 can be disassembled in peacetime. Therefore, the protection module 5 is easy to load and unload, and is convenient to replace and carry.

[0026] The surface density of the protection module 5 is less than or equal to 40 kg / m 2The thickness of the protection module 5 is less than or equal to 20 mm. The high-strength structure in the protection module 5 is a perforated armored steel 2. The perforated armored steel 2 is made of armored steel, aluminum alloy and titanium alloy. The perforated armored steel 2 is provided with circular holes with a diameter of 7 mm to 10 mm at equal intervals. By setting the holes on the perforated armored steel 2, the protection module 5 can improve the armored vehicle's ability to defend against drone attacks without significantly increasing the weight of the armored vehicle, and can effectively protect the vehicle from damage by drone bullets and explosives.

[0027] When the protection module 5 is impacted, the protection module 5 guides the explosion shock wave into the foam aluminum layer 3 through the perforated armor steel 2. Since the foam aluminum core layer 3 adopts a density between 200kg / m 3 -1000kg / m 3 The closed-cell foam aluminum can therefore be used for energy absorption and buffering through the foam aluminum layer 3, thereby improving the protective effect of the protection module 5 on the armored vehicle roof 7, and can effectively protect the vehicle from damage by drone bullets and explosives.

[0028] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent replacement and improvement made to the above embodiments without departing from the content of the technical solution of the present invention, based on the technical essence of the present invention, within the spirit and principles of the present invention, still fall within the protection scope of the technical solution of the present invention.
