Description

Technical Field

[0001] The utility model belongs to the field of vehicle-mounted weapon station protection, and specifically relates to a protective armor structure and a vehicle-mounted weapon station protective armor kit. Background Art

[0002] Armored vehicles and other combat vehicles need to have a vehicle-mounted weapon station in the horizontal center position on the top of the vehicle body. However, the vehicle-mounted weapon station is located in a prominent position and is vulnerable to attack. Therefore, it is necessary to deploy a protective armor structure on the periphery of the vehicle-mounted weapon station for bulletproofing in order to ensure reliable protection while ensuring firepower output.

[0003] At present, the installation structure of bulletproof armor is varied, including a method of directly passing through the armor plate and fixing it to the vehicle-mounted weapon station through fasteners, and a method of adding a pressure strip on the outer edge of the bulletproof armor and fixing the pressure strip to the vehicle-mounted weapon station with screws to achieve connection. For bulletproof plates made of ceramic materials, ceramics are materials with very high hardness, so fasteners cannot act directly on the ceramic plate. Once directly acting on the ceramic plate, if the stress is concentrated, it is easy to cause cracks. The fasteners will generate stress on the ceramic plate, which will cause cracks in the ceramic plate and reduce the bulletproof performance. In the prior art, the ceramic protective armor plate is generally fixed directly to the vehicle-mounted weapon station by bonding or bolts. However, for parts with irregular shapes or that need to be replaced, the installation operation of directly fixing the protective armor structure to the outside is cumbersome, and small-sized bulletproof ceramics need to be used for splicing. This splicing treatment method is bound to reduce the bulletproof performance; and after the front of the ceramic protective armor plate is hit by a bullet, the deformation will directly affect the high-precision instruments on the back, and the ceramic bulletproof plate after being hit is difficult to replace.

[0004] Therefore, it is now necessary to develop a protective armor structure that is easy to assemble and has good bulletproof performance and a protective armor kit for a vehicle-mounted weapon station to solve the above-mentioned problems in the prior art. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the present invention, unless otherwise specified or limited, the terms "connection", "fixation" and the like should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] As attached Figure 1 -Attached Figure 4 As shown, the utility model is a protective armor structure, including a protective plate 2, the protective plate 2 includes a PE plate 21 and a ceramic plate 22, wherein the PE plate 21 is made of PE material and can be used to absorb kinetic energy. In a preferred embodiment, the PE plate 21 of PE material is prepared by combining PEUD cloth and a membrane tape, which is specifically an existing structure and will not be described in detail here. The ceramic plate 22 is prepared by pressureless sintering using powder nano-technology, is the core of the protective armor structure, and plays a role in armor-breaking and energy-absorbing. Specifically, the existing structure is also adopted, which will not be described in detail here. The ceramic plate 22 is bonded to one side of the PE plate 21. When in specific use, the ceramic plate 22 is located on the outside to withstand the first impact. The ceramic plate 22 is bonded and fixed to the PE plate 21, preferably by a hot pressing composite process to ensure good fixing reliability. An opening Ⅰ221 is provided on the ceramic plate 22, and the opening Ⅰ221 exposes the PE plate 21. The opening Ⅰ221 and the exposed portion of the PE plate 21 are used to install fasteners 3. The fasteners 3 are used to install the protective armor structure to the structure to be protected, thereby completing the installation of the protective armor structure.

[0033] The utility model, by bonding the ceramic plate 22 to the PE plate 21, is convenient for fixing the ceramic plate 22 on the structure to be protected, and can also improve the overall anti-ballistic performance, and by setting the opening Ⅰ221 on the ceramic plate 22, and the fastener 3 fixes the PE plate 21 and the structure to be protected through the opening Ⅰ221, it is convenient for fixing the fastener 3, the opening Ⅰ221 is used to make room for the installation of the fastener 3, and can also provide positioning and limit for the installation of the fastener 3, and on the other hand, the fastener 3 can also make up for the vacant bulletproof position caused by the opening Ⅰ221, thereby avoiding the bulletproof effect being too weak when the ammunition is fired at the opening Ⅰ221. Thus, it is achieved that the installation difficulty is simplified without affecting the bulletproof effect.

[0034] In one preferred embodiment, the fastener 3 is a bolt, that is, the bolt includes a screw rod and a screw head, and the end of the screw rod has an external thread. In this case, a threaded hole matching the external thread is provided on the structure to be protected. The bolt is used as the fastener 3, which is simple and convenient to install and has a stable and reliable connection.

[0035] The size of the opening Ⅰ221 is larger than the size of the screw head of the bolt, that is, the screw head can be embedded in the opening Ⅰ221. On the one hand, it can prevent the bolt from protruding from the bulletproof surface formed by the ceramic plate 22, causing the bulletproof surface to be uneven. On the other hand, when the screw head hits the bullet, the screw head can be deformed like the side wall of the opening Ⅰ221, avoiding the screw head from being completely broken and affecting the installation stability, thereby improving the bulletproof effect.

[0036] The PE plate 21 is provided with an opening II211 coaxial with the opening I221, the size of the opening II211 is larger than the screw diameter of the bolt and smaller than the screw head size of the bolt, that is, the screw is arranged through the opening II211, so as to simplify the installation difficulty of the screw, wherein the opening II211 can be a through hole or a screw hole, which is selected according to specific needs. At this time, the opening I221 and the opening II211 form a stepped hole, and the end of the screw head directly abuts against the PE plate 21, so that the fastener 3 is completely fixed through the PE plate 21, avoiding the extrusion stress generated by the connecting bolt to affect the ceramic plate 22;

[0037] The bolt is screwed to the structure to be protected through opening I 221 and opening II 211 in turn, that is, after installation, the head of the bolt is located in opening I 221, a part of the screw rod close to the head of the bolt rod is located in opening II 211, and the rest of the screw rod with external threads is located in the structure to be protected.

[0038] In other embodiments, the fastener 3 may be a fastener such as a rivet, a screw, or a pin. The provision of the opening Ⅰ221 facilitates the installation of the fastener 3, and the opening Ⅰ221 may be formed by the fastener 3 penetrating during installation.

[0039] In one embodiment, the ceramic plate 22 is provided with a plurality of pieces, and the plurality of ceramic plates 22 are spliced ​​together to form a protective surface. Such a configuration can reduce the size of the ceramic plate 22, thereby reducing the production cost;

[0040] At least a portion of the ceramic plate 22 is provided with an opening Ⅰ221 for installing the fastener 3 .

[0041] In one of the embodiments, a step 222 is provided on the opposite side of two adjacent ceramic plates 22, and the two adjacent ceramic plates 22 are overlapped with each other through the step 222. Such a configuration allows the two adjacent ceramic plates 22 to be connected to each other without punching holes, while also improving the ballistic performance of the joint between the two adjacent ceramic plates 22, thereby ensuring the overall protective performance of the protective armor structure.
