Description

Technical Field

[0001] The invention relates to a triangular foldable grid armor structure, belonging to the technical field of equipment protection. Background Art

[0002] With the development of high-tech equipment, in modern battlefields, strong enemies and opponents use hollow anti-tank ammunition, drones, and cruise missiles in large quantities. The "top attack method" with the characteristics of small group multi-path and multi-point attack has gradually become one of the attack methods that cannot be ignored in modern local battlefields. The living environment of various weapons and equipment and military facilities in battlefield environments is becoming increasingly harsh. In particular, a civilian drone carrying a grenade can pose a strong threat to military facilities, and a rocket can make an armored vehicle lose the ability to continue fighting. How to improve the protection capabilities of weapons and equipment and military facilities in battlefield environments has become a practical problem that needs to be solved urgently.

[0003] The design concept of the grid armor is to protect against threats from the enemy by using statistical probability. It is specially developed to resist attacks from armor-piercing projectiles. It has a light weight, simple structure, good manufacturing processability, and high protection performance against armor-piercing projectiles. The defensive mechanism of grille armor can be divided into the following points: (1) Grille armor can destroy the standard firing height of armor-piercing projectiles. When an armor-piercing projectile hits the grille armor, it will detonate in advance. The grille armor maintains a certain distance from the main armor, causing the metal jet of the armor-piercing projectile to break, stretching and interfering with the metal jet, thereby weakening the armor-piercing power and losing the optimal armor-piercing ability; (2) Grille armor can damage the body and fuze of the incoming armor-piercing projectile, preventing it from exploding normally. The tiny grille can jam the armor-piercing projectile with a caliber larger than the grille spacing, tearing the wind cap of the armor-piercing projectile, and cutting off the wire connecting the electric detonator at the bottom of the projectile, so that the piezoelectric fuze at the tip of the warhead cannot touch the main armor and cannot detonate; (3) Even if the armor-piercing projectile detonates successfully, the grille will block the armor-piercing ammunition hood, causing the hood to twist and deform, affecting the formation of a complete armor-piercing jet and weakening the armor-piercing ability of the armor-piercing projectile.

[0004] Grille armor is "simple, practical and easy to install". It can meet the design and manufacturing requirements through existing technologies and processes, without investing a lot of research and development funds and procurement costs. It has a high cost-effectiveness ratio. After the design is finalized, it can be quickly equipped to the troops and used for various types of in-service equipment to protect armored equipment worth millions or even tens of millions of yuan from effective attacks by anti-tank weapons. Facing the high-tech local wars that may occur in the future, adding grille armor to equipment to enhance battlefield survivability has important military value. However, the disadvantages of grille armor are also obvious: ① Because it is equivalent to installing a circle of "bird cages" on the outside of the armored vehicle, the flexibility and maneuverability of the armored vehicle are reduced; ② There is a certain probability that the grille armor cannot be effectively protected, especially for armor-piercing shells attacking at large angles, its protection ability is almost zero, which is also the main reason why the grille armor is also called "probabilistic armor". On the whole, the protection efficiency of existing grille armor against armor-piercing shells is about 50%. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a triangular foldable grille armor structure that can cope with armor-piercing shells attacking at large angles and improve the flexibility and passability of vehicles, thereby improving the protective efficiency of the grille armor, the battlefield support capability of weapons and equipment, and the ability to effectively respond to multiple threats.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A triangular foldable grille armor structure comprises a foldable grille bracket mounted on a mounting support and a triangular grille unit mounted on the foldable grille bracket. The triangular grille unit comprises grille frames arranged side by side; The grid frame is provided with a telescopic shaft mounting hole; A telescopic shaft is installed in the telescopic shaft installation hole; The retractable shaft is provided with a grille unit.

[0007] Furthermore, the grille unit includes a mounting shaft and a blocking piece arranged on the outside of the mounting shaft, the mounting shaft is provided with a through hole along the axial direction, and the mounting shaft sleeve is arranged on the telescopic shaft.

[0008] Furthermore, there are three blocking pieces, and the blocking pieces are evenly arranged on the outside of the wearing shaft.

[0009] Furthermore, the inner core of the baffle is made of silicon carbide ceramic material, and the outer side is covered with RHA armor steel.

[0010] Furthermore, the foldable grid support includes a connecting rod that simultaneously connects the mounting support and the upper or lower end of the grid frame, and a folding support rod with one end connected to the upper end of the mounting support, and the other end of the folding support rod is connected to the lower end of the grid frame.

[0011] Furthermore, one end of the folding support rod is hinged to the lower end of the grid frame, and the other end of the folding support rod is clamped to the upper end of the mounting support.

[0012] The beneficial effects of adopting the above technical solution are: The grille armor unit of the present invention abandons the traditional sheet structure and adopts a new triangular pyramid structure. Since it can rotate around a retractable axis, when facing the threat of large-angle shooting of shaped-charge ammunition, the grille unit can reduce the impact force between it and the shaped-charge ammunition fuse and avoid the triggering of the fuse, thereby effectively improving the grille armor against the threat of large-angle shooting of shaped-charge ammunition.

[0013] The novel grille unit material of the present invention adopts RHA-silicon carbide ceramic layered composite material, wherein the first and third layers adopt RHA armor steel, and the second middle layer adopts ceramic material. The traditional grille armor material is upgraded from RHA armor steel to RHA-silicon carbide ceramic sandwich composite material, which not only retains the good plasticity of RHA armor steel, but also reflects the rigidity and hardness of armor ceramics, and can effectively cope with the threat of high-speed ammunition.

[0014] The new grille unit of the present invention adopts the installation and connection method of "grille armor unit-retractable shaft assembly-foldable grille bracket", which is characterized by: ① the grille armor structure unit is modular; ② the grille armor structure unit can be quickly disassembled and installed, realizing the convenience of equipment guarantee; ③ the grille unit can rotate around the retractable shaft assembly to achieve high performance of protection. The present invention changes the connection method between the grille unit and the grille frame from welding to a modular installation method. The retractable shaft can be retracted by pressing the two ends of the retractable shaft, so as to conveniently cooperate with the grille frame to complete the installation and disassembly of the new grille armor unit. This installation method improves the maintenance convenience and equipment guarantee of the grille armor.

[0015] The grid support of the present invention is a foldable structure design. The grid frame integrates the new grid armor structure into the armored vehicle through the foldable structure. If an obstacle is encountered, the grid armor can be quickly folded up. After installation, the original combat performance of the armored vehicle will not be affected, and the mobility and passability of the original vehicle are maintained to the maximum extent. The grid armor is used to protect the front, flanks, rear, engine and turret top of the armored vehicle, which can improve the protection performance and achieve all-directional protection.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] As attached Figure 1-6 As shown, this embodiment provides a triangular foldable grille armor structure, which includes a foldable grille bracket installed on a mounting support and a triangular grille unit installed on the foldable grille bracket, the triangular grille unit includes grille frames 1 arranged side by side; a telescopic shaft mounting hole 101 is provided on the grille frame 1; a telescopic shaft 2 is passed through the telescopic shaft mounting hole 101; a grille unit 3 is passed through the telescopic shaft 2, the grille unit 3 includes a passing shaft 301 and a blocking piece 302 arranged on the outside of the passing shaft 301, the passing shaft 301 is provided with a through hole along the axial direction, the passing shaft 301 is sleeved on the telescopic shaft 2, there are three blocking pieces 302, and the blocking pieces 302 are evenly distributed on the outside of the passing shaft 301. The unit structure adopted by the grille unit of the present invention abandons the traditional sheet structure. Since it can rotate around the retractable axis, when facing the threat of large-angle shooting of shaped charge munitions, the grille unit can reduce the impact force between it and the shaped charge fuze and avoid triggering the fuze, thereby effectively improving the grille armor against the threat of large-angle shooting of shaped charge munitions.

[0019] The inner core of the baffle 302 is made of silicon carbide ceramic material, and the outer side is covered with RHA armor steel. The traditional grille armor material is upgraded from RHA armor steel to RHA-silicon carbide ceramic sandwich composite material. This solution not only retains the good plasticity of RHA armor steel, but also reflects the stiffness and hardness of armor ceramics, and can effectively deal with the threat of high-speed ammunition.

[0020] The foldable grille support comprises a connecting rod 4 which simultaneously connects the mounting support and the upper or lower end of the grille frame 1, and a folding support rod 5 which has one end connected to the upper end of the mounting support, the other end of the folding support rod 5 is connected to the lower end of the grille frame 1, one end of the folding support rod 5 is hinged at the lower end of the grille frame 1, and the other end of the folding support rod 5 is clamped at the upper end of the mounting support. That is, the upper side of the foldable grille support is connected to the mounting support by one end of the connecting rod, and the other end is connected to the grille frame; the lower side of the foldable grille support is also connected to the mounting support by one end of another connecting rod, and the other end is connected to the grille frame; the grille frame is provided with a folding support rod 5, and the folding support rod 5 can adjust the unfolding and folding of the foldable support (the clamping end is released to realize folding, and the clamping end is clamped to realize unfolding), and a triangular stable support structure is realized after clamping; one end of the folding support rod is connected to the grille frame (lower), and the other end is connected to the mounting support (upper); the mounting support is fixed on the armored vehicle.

[0021] The folding structure of the present invention is not limited to the above-mentioned structural form. For example, if a form similar to a hydraulic rod in a car trunk is adopted, as long as the folding and propping up of the grille support can be achieved, it should be understood to be within the protection scope of the present invention.

[0022] The specific usage principles are as follows: In traditional grille armor, the connection between the sheet grid unit and the grille frame is welding. This design changes the connection between the grille unit and the grille frame from welding to a modular installation method. By pressing the two ends of the retractable and retractable shaft, the retractable shaft can be retracted, so that the installation and disassembly of the new grille armor unit can be completed conveniently with the grille frame. This installation method improves the maintenance convenience and equipment security of the grille armor. The present invention no longer uses welded steel wide strips, and calculates the appropriate spacing according to the size of the projectile to be protected. This solution can enhance the defense capability against oblique rockets with large incident angles, and will greatly improve the interception success rate. The grille frame integrates the new grille armor structure into the armored vehicle through a folding structure. If an obstacle is encountered, the new grille armor can be quickly folded up. After installation, the original combat performance of the armored vehicle will not be affected, and the mobility and passability of the original vehicle are maintained to the maximum extent. The grille armor is used to protect the front, flanks, rear, engine and turret top of the armored vehicle, which can improve the protection performance and achieve all-directional protection. The present invention improves the performance of resisting large-angle penetration of shaped-charge ammunition; while retaining its strength, it increases the rigidity of the armored grille, and can effectively cope with the threat of high-speed projectiles; the convenient installation method improves the convenience of battlefield maintenance of armored vehicles and the equipment security.

[0023] The grille armor of the present invention adopts a modular structure design for the grille unit, follows the principle of module interchangeability, meets the interchangeability requirements, is applicable to the same model or the same type of equipment, and the new grille armor is selected according to the nature of the mission and the threat level. After the grille armor of the present invention is damaged, it does not need to be returned to the armory or repair base. It can be installed and disassembled by the crew in a short time during maneuvering, transportation or in the war zone using the accompanying tools. It is equipped with a quick-release device. Once a module of the new grille armor structure is damaged, it can be quickly replaced without other equipment. It has the advantages of high combat effectiveness and easy battlefield operation and use.

[0024] The grid armor structure design of the present invention constructs a set of grid "golden bell" that "defends the body" and "guards the top of the head". Taking a certain type of main battle tank in service as an example, the turret is relatively small in size, and the components such as the sighting device, optoelectronic countermeasure device, crew hatch, anti-aircraft machine gun, shell ejection window, and communication antenna occupy a considerable part of the top area of ​​the turret. After installing the top protection reactive armor, the area that can be protected is still limited. The grid armor can prevent anti-tank weapons from directly attacking the top of the turret, protect the ammunition in the turret, and reduce the possibility of sympathetic explosion. It has important military significance for improving the battlefield survivability of weapons and equipment facing the threat of enemy shaped-energy ammunition, drones, cruise missiles, etc., and exerting combat effectiveness.
