Description

Technical Field

[0001] This invention relates to the field of armor protection technology, and in particular to a barbed grille armor bar. Background Technology

[0002] With the deployment of drones, loitering munitions, and new anti-tank munitions in actual combat, the protection of equipment and personnel from overhead attacks has become extremely important. Adding slat armor to the weak and vulnerable parts of equipment is an important way to enhance the overall protection capabilities of equipment.

[0003] The slats are an important component of slat armor and the key to its protective capabilities. The strength of the slats themselves and the gaps between adjacent slats can damage the incoming armor-piercing projectile and its fuse, preventing it from detonating properly. The small gaps between the slats can trap armor-piercing projectiles with a caliber larger than the slat spacing, tear apart the projectile's wind cap, and sever the wires connecting the electric detonator at the projectile's base, preventing the piezoelectric fuse at the projectile's tip from contacting the main armor and detonating it. Currently, most slats are made of iron-based alloy metal strips with a high surface density (greater than 25 kg / m2), resulting in relatively weak protective capabilities (only able to withstand one round of attack and easily deformable). They also have poor ricochet effect against projectile ammunition. To address this, the invention with patent number "202411937404.3" and title "A Triangular Foldable Slat Armor Structure" proposes a new type of slat armor structure, including a foldable slat bracket mounted on a mounting base and triangular slat units mounted on the foldable slat bracket. The slats of this structure are triangular, composed of baffles and a mounting shaft. The mounting shaft is sleeved on a telescopic shaft to form closely spaced slat units.

[0004] Although the slats in the aforementioned new slat armor structure have changed in shape, they are still solid with a high surface density. This limits their ability to jam when the slats deform instantaneously during projectile impact. Furthermore, these triangular slat units are still hard planes, which cannot function as anti-ballistic munitions or pierce drones when subjected to projectiles, fragments, or suicide drones. Therefore, the aforementioned new slat structure is difficult to meet the requirements of high-intensity, high-impact attacks. Summary of the Invention

[0005] The purpose of this invention is to provide a spiked slat armor bar to solve the problems existing in the prior art and to cope with high attack situations.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides a barbed grille armor bar, comprising at least one grille unit; the grille unit includes a bar body, a non-Newtonian fluid, and at least one barbed strip; the bar body is used to be disposed on the outer surface of the protective equipment; the bar body has a hollow cavity; the non-Newtonian fluid is filled in the hollow cavity; each of the barbed strips is fixedly disposed on the outer side wall of the bar body, and each of the barbed strips is arranged in parallel, the length extension direction of the barbed strips being perpendicular to the outer surface of the protective equipment.

[0007] Preferably, the cross-section of the grid bar body is cylindrical, and the hollow cavity is a cylindrical cavity coaxial with the grid bar body, the radius of the cylindrical cavity being 1 / 2 of the radius of the grid bar body.

[0008] Preferably, the grid bar body has at least one opening, the opening corresponds one-to-one with the barbed bar, and the barbed bar is fixedly disposed at the opening.

[0009] Preferably, the barbed strip is fixedly mounted on the connecting nut, and the connecting nut is fixed and closed at the opening.

[0010] Preferably, when there are multiple grid units, the axis of the grid bar body of the grid unit is parallel to the first direction and perpendicular to the second direction; in the first direction or the second direction, the grid bar body of the grid unit is directly fixedly connected to the grid bar body of the adjacent grid unit through a connecting rod or is hinged to each other through a connecting member.

[0011] Preferably, the connector includes a first connecting piece and a second connecting piece, the first connecting piece and the second connecting piece are arranged in parallel, and the same end of the first connecting piece and the second connecting piece are rotatably connected to the grid bar body of the same side of the grid unit about a first axis, and the other end of the first connecting piece and the second connecting piece are rotatably connected to the grid bar body of another grid unit on the same side about a second axis, the first axis and the second axis being parallel.

[0012] Preferably, the barbed strip is made of metal or carbon fiber reinforced composite material.

[0013] Preferably, the material of the grid bar body is an alloy material.

[0014] Preferably, the ends of the barbed strips are pointed.

[0015] Preferably, the length of the barbed strip is 30cm to 50cm.

[0016] The present invention achieves the following technical effects compared to the prior art: The serrated lattice armor slats provided by this invention, by filling the slat body with a non-Newtonian fluid, when impacted, the impacting projectile or fragments first contact the slat body, causing plastic deformation of the slat body. Although the slat body is a hollow structure, its walls are relatively thick, resulting in high strength. Compared to a single solid slat, the hollow structure has better toughness while significantly reducing the density of the slat body, and has a stronger ability to trap projectiles and tear apart projectile wind caps. Furthermore, the instantaneous deformation of the slat body after impact causes shear thickening of the non-Newtonian fluid within its cavity. The non-Newtonian fluid filler hardens and expands rapidly under impact, dispersing the impact kinetic energy and the large amount of internal energy generated by the impact; the barbs on the grid body can improve the protective performance of the armor grid structure. When attacked by grenades or rockets launched by drones, the barbs can play the role of grid deformation and interception, while also ejecting the projectiles or piercing the suicide drones. The barbs also have the ability to change the incident direction of the attacking projectile and deflect fragments, thereby reducing the vertical impact of the projectile on the protected object or the damage to the armor from the fragments.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a spiked slat armor bar to solve the problems existing in the prior art and to cope with high attack situations.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 This embodiment provides a barbed grille armor strip, such as... Figures 1-5 As shown, it includes at least one grid unit; the grid unit includes a grid body 1, a non-Newtonian fluid and at least one barbed strip 3; the grid body 1 is used to be disposed on the outer surface of the protective equipment; the grid body 1 has a hollow cavity 101; the non-Newtonian fluid is filled in the hollow cavity 101 (fully filled); each barbed strip 3 is fixedly disposed on the outer side wall of the grid body 1, and each barbed strip 3 is arranged in parallel, and the length extension direction of the barbed strip 3 is perpendicular to the outer surface of the protective equipment.

[0024] By filling the interior of the grid body 1 with a non-Newtonian fluid, when impacted, the projectile or fragment first contacts the grid body 1, causing plastic deformation. Although the grid body 1 is a hollow structure, its walls are relatively thick, resulting in high strength. Compared to a single solid grid, the hollow structure exhibits better toughness while significantly reducing the density of the grid body 1, thus enhancing its ability to trap projectiles and tear apart projectile wind caps. Furthermore, the instantaneous deformation of the grid body 1 upon impact causes shear thickening of the non-Newtonian fluid within its cavity, further enhancing the filling effect of the non-Newtonian fluid. The filling material hardens and expands rapidly under impact, dispersing the impact kinetic energy and a large amount of internal energy generated by the impact; the barbed strips 3 on the grid body 1 can improve the protective performance of the armor grid structure. When attacked by grenades or rockets launched by drones, the barbed strips 3 can play the role of grid deformation and interception. At the same time, the barbed strips 3 can eject the launched ammunition or pierce the suicide drone. The barbed strips 3 also have the ability to change the incident direction of the attacking projectile and bounce the fragments, thereby reducing the vertical impact of the projectile on the protected object or the damage of the fragments to the armor.

[0025] The following are the settings instructions for the grid body 1: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2As shown, the cross-section of the grid body 1 is cylindrical, and the hollow cavity 101 is a cylindrical cavity coaxial with the grid body 1, with the radius of the cylindrical cavity being 1 / 2 of the radius of the grid body 1. That is, the hollow cavity 101 of the grid body 1 is a cylindrical cavity closed at both ends.

[0026] In the optional solutions of this embodiment, it is more preferred that the material of the grid body 1 is an alloy material, such as iron, aluminum, titanium and other alloy materials.

[0027] The following are the settings instructions for the barbed strip 3: Specifically, such as Figure 5 As shown, the outer wall of the barbed strip 3 can be smooth or it can have a raised structure 302 for protection (such as...). Figure 5 (as shown), to enhance its protective capabilities.

[0028] In the optional solutions of this embodiment, it is more preferred that the material of the barbed strip 3 is metal or carbon fiber reinforced composite material.

[0029] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 4 and Figure 5 As shown, the end of the barbed strip 3 is a pointed tip 301.

[0030] Specifically, the end of the barbed strip 3 is oriented perpendicular to the outer surface of the protective equipment.

[0031] In the optional solutions of this embodiment, the preferred length of the barbed strip 3 is 30cm to 50cm. Specifically, the length of the barbed strip 3 is determined according to the service characteristics and protection requirements of the protected object.

[0032] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the grid bar body 1 has at least one opening 102 (when there is only one opening 102, a portion of the opening 102 needs to be left open for venting when adding non-Newtonian fluid, so that the non-Newtonian fluid can be added smoothly). The opening 102 corresponds one-to-one with the barbed bar 3, and the barbed bar 3 is fixedly set at the opening 102.

[0033] Specifically, the number and position of the openings 102 and the barbed strips 3 can be reasonably set according to the protection requirements, such as the distribution of the openings 102 being equally spaced or set as a combination of dense and sparse.

[0034] Specifically, non-Newtonian fluids can be injected into or discharged from the hollow cavity 101 through the opening 102 on the grid body 1.

[0035] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-4As shown, the barbed strip 3 is fixedly mounted on the connecting nut 2, and the connecting nut 2 is fixed and closed at the opening 102.

[0036] Specifically, such as Figures 1-4 As shown, the connecting nut 2 is threadedly sealed at the opening 102, and the connecting nut 2 has a connecting internal threaded hole 201. One end of the barbed strip 3 has a connecting external thread 303, which is threaded into the connecting internal threaded hole 201 to fix the barbed strip 3 to the connecting nut 2. That is, one end of the connecting nut 2 is used to block the opening 102 on the grid body 1 (the lower end of the connecting nut 2 is provided with a blocking external thread 202, and the opening 102 of the grid body 1 is provided with a blocking internal threaded hole, and the blocking external thread 202 is threaded into the blocking internal threaded hole to achieve the purpose of the connecting nut 2 blocking its opening 102), and the other end is used to connect the barbed strip 3.

[0037] Specifically, the connecting nut 2 can serve as a support base for the barbed strip 3, stabilizing the installation posture of the barbed strip 3.

[0038] Specifically, the connecting nut 2 is made of iron-based alloy material.

[0039] Specifically, the connecting nut 2 can be a commercially available shelf product, so that it can be easily replaced if damaged.

[0040] The following are the settings instructions regarding the combination of multiple grid units: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 4 As shown, when there are multiple grid units, the axis of the grid bar body 1 of the grid unit is parallel to the first direction and perpendicular to the second direction (the axis of the grid bar body 1 of the grid unit is perpendicular to the second direction); in the first direction or the second direction, the grid bar body 1 of the grid unit is directly fixedly connected to the grid bar body 1 of the adjacent grid unit by a connecting rod 4 (such as by welding, etc.).

The first and second connecting pieces are arranged in parallel, and each end of the first and second connecting pieces is rotatably connected to the grid body 1 of the same-side grid unit about a first axis. The other ends of the first and second connecting pieces are rotatably connected to the grid body 1 of another grid unit on the same side about a second axis, which is parallel to the first axis. By using a hinged connector, multiple grid units can be configured into a more flexible shape to better fit the non-planar outer surface of the protective equipment.

[0042] Specifically, in two adjacent grid units, the grid bar body 1 of one grid unit is the first grid bar body, and the grid bar body 1 of the other grid unit is the second grid bar body (the two ends of the first grid bar body and the second grid bar body are the first end and the second end, respectively): In the first direction, the first end of the first grid bar body is rotatably connected to the first end of the second grid bar body through a first connecting piece and a second connecting piece (or only one connecting piece can be used to achieve the rotatable connection between the first end of the first grid bar body and the first end of the second grid bar body). At this time, the first connecting piece and the second connecting piece are arranged in parallel opposite directions at the ends of the first grid bar body and the second grid bar body. Similarly, the second end of the first grid bar body and the second end of the second grid bar body are connected to other grid units. In the second direction, the first end of the first grid bar body is rotatably connected to the first end of the second grid bar body through the first connecting piece, and the second end of the first grid bar body is rotatably connected to the second end of the second grid bar body through the second connecting piece.

[0043] Specifically, both the first connecting piece and the second connecting piece can be detachably connected to the grid body 1 of each grid unit to facilitate disassembly and replacement, thereby enabling the damaged protective structure to be quickly disassembled and replaced in a short time, greatly improving the battlefield adaptability of the grid armor.

[0044] Specifically, in addition to the first and second connecting pieces mentioned above, the connectors can also be metal strips (i.e., connecting rods 4), which are welded together to connect adjacent grid units (e.g., ...). Figure 4 (As shown).
