Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulletproof plate technology, and in particular to an elastically constrained composite bulletproof plate. Background Technology
[0002] The search for lighter, more protective, and more manufacturable materials and structures in the field of protective equipment technology has always been the goal and direction of this field. By changing the trajectory of projectiles, deflecting incoming projectiles is one of the technical ways to improve the ballistic protection capability of armor. Ballistic plates can absorb the kinetic energy of projectiles or shrapnel, and have a significant protective effect against low-speed projectiles or shrapnel. Under controlled conditions of certain indentation, they can reduce the damage to the chest and abdomen of the human body.
[0003] Regarding the aforementioned technologies, many existing traditional bulletproof plates are made of materials with high density, resulting in a heavy overall weight. For example, while ceramic bulletproof plates offer good ballistic protection, the ceramic material itself is heavy. For personnel who need to operate for extended periods, such as soldiers on patrol or police officers in daily duties, excessively heavy bulletproof plates increase the physical burden. Therefore, this invention provides an elastically restrained composite bulletproof plate. Utility Model Content
[0004] The purpose of this application is to provide an elastically constrained composite bulletproof plate to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: an elastically restrained composite bulletproof plate, comprising a baffle, a buffer plate being disposed on the outer side of the baffle, the buffer plate being made of aluminum foam, and a dispersion component being disposed on the outer side of the baffle; the dispersion component comprising a plurality of stacked ceramic frames, the ceramic frames being honeycomb-shaped, a plurality of ceramic trapezoidal frames being fixedly connected to the outer side of the ceramic frames, the ceramic frames and the ceramic trapezoidal frames being made of silicon carbide ceramic, and a woven layer being disposed on the outer side of the baffle, the ceramic frames and the ceramic trapezoidal frames being connected to the woven layer.
[0006] Preferably, the baffle is made of aluminum alloy plate, and the woven layer is made of ultra-high molecular weight polyethylene fiber.
[0007] Preferably, a first ceramic layer is provided on the outer side of the braided layer, and the first ceramic layer is made of boron carbide ceramic plate.
[0008] Preferably, the outer side of the first ceramic layer is provided with a plurality of V-shaped grooves, and the plurality of V-shaped grooves are evenly arranged.
[0009] Preferably, an elastic plate is provided on the outer side of the first ceramic layer, and the elastic plate is made of polyurethane elastomer.
[0010] Preferably, the outer side of the elastic plate has multiple grooves, and an elastic block is disposed in the groove, the elastic block being made of rubber.
[0011] Preferably, a second ceramic layer is provided on the outer side of the elastic plate, and the second ceramic layer is made of alumina ceramic layer.
[0012] In summary, the technical effects and advantages of this utility model are as follows:
[0013] 1. In this utility model, by combining a honeycomb-shaped ceramic frame and a ceramic trapezoidal frame, the honeycomb structure has many gaps. These gaps reduce the actual amount of ceramic material used. The presence of the honeycomb ceramic sheet is equivalent to increasing the number of protective layers. Even if the honeycomb ceramic sheet breaks in a local area after the bulletproof vest is hit by a bullet, the surrounding honeycomb units can still continue to play a protective role due to the interconnectivity of its honeycomb structure and the overall stability.
[0014] 2. In this utility model, the V-shaped groove can guide the direction of the bullet's movement, so that the fragments and energy generated after impacting the first ceramic layer are dispersed in a predetermined direction, avoiding the fragments from concentrating in a certain area and causing excessive damage to the bulletproof plate. At the same time, it also helps to improve the bulletproof plate's protective performance against multiple impacts. Attached Figure Description

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] Example: Reference Figure 1-3The illustrated elastic constraint composite bulletproof plate includes a baffle 1 made of aluminum alloy, possessing certain strength and toughness, providing a basic support structure for the entire bulletproof plate, resisting the impact of bullets, and preventing direct penetration. A buffer plate 4, made of aluminum foam, is disposed on the outer side of the baffle 1. Aluminum foam is lightweight and has good cushioning properties, effectively absorbing some of the energy generated during bullet impact, reducing the impact force on subsequent components, and minimizing the damage to the overall structure of the bulletproof plate. A dispersion component is disposed on the outer side of the baffle 1, comprising multiple stacked ceramic frames 2 arranged in a honeycomb pattern. This honeycomb structure can evenly disperse the impact force of the bullet in all directions. To avoid excessive local stress that could damage the structure, multiple ceramic trapezoidal frames 3 are fixedly connected to the outer side of the ceramic frame 2. Both the ceramic frame 2 and the ceramic trapezoidal frames 3 are made of silicon carbide ceramic. Silicon carbide ceramic has high hardness and strong wear resistance, which can further enhance the bullet resistance of the dispersion component, effectively break and disperse the bullet's energy, disperse the bullet's impact force, and reduce the pressure on a single point of the bulletproof plate. The outer side of the baffle 1 is provided with a woven layer 5, which is made of ultra-high molecular weight polyethylene fiber. This fiber has the characteristics of high strength, high modulus, and low density, which can further enhance the overall strength and toughness of the bulletproof plate. At the same time, its flexibility can buffer the impact force of the bullet to a certain extent. In conjunction with the dispersion component, it can better prevent the bullet from penetrating.Both the ceramic frame 2 and the ceramic trapezoidal frame 3 are connected to the woven layer 5, ensuring the synergistic effect between the components and forming a complete protective system. A first ceramic layer 6 is provided on the outer side of the woven layer 5. The first ceramic layer 6 is made of boron carbide ceramic plate. Boron carbide ceramic has extremely high hardness and can effectively resist direct impact from bullets, playing a crucial protective role in the bulletproof process, blocking bullet penetration and further breaking the bullet, thus consuming its energy. Multiple V-grooves 11 are provided on the outer side of the first ceramic layer 6. These V-grooves 11 are evenly arranged and can guide the bullet's movement direction, dispersing the fragments and energy generated after impacting the first ceramic layer 6 in a predetermined direction. This prevents fragments from concentrating in one area and causing excessive damage to the bulletproof plate, while also helping to improve the bulletproof plate's protective performance against multiple impacts. An elastic plate 7 is provided on the outer side of the first ceramic layer 6. The elastic plate 7 is made of polyurethane elastomer. The body has good elasticity and cushioning performance, which can further buffer the remaining impact force after the bullet hits the first ceramic layer 6, reducing the pressure on subsequent components. At the same time, its elasticity can also allow the bulletproof plate to quickly restore its shape after being impacted, ensuring the continuous protective capability of the bulletproof plate. Multiple grooves 10 are opened on the outer side of the elastic plate 7, and elastic blocks 8 are set in the grooves 10. The elastic blocks 8 are made of rubber blocks. The rubber blocks 8 can provide additional cushioning and energy absorption when the bullet hits, further reducing the impact force of the bullet. Together with the elastic plate 7, they enhance the cushioning performance and protective effect of the bulletproof plate. A second ceramic layer 9 is set on the outer side of the elastic plate 7. The second ceramic layer 9 is made of alumina ceramic layer. The alumina ceramic layer can provide additional protection to prevent the bullet from penetrating the elastic plate 7 and continuing to cause harm to the human body. At the same time, it can also disperse the remaining energy of the bullet to a certain extent, improving the overall protective performance of the bulletproof plate.
