Description

Technical Field

[0001] This utility model belongs to the field of firearms, and in particular relates to a special anti-drone bullet based on standard small-caliber firearms. Background Technology

[0002] In existing technologies, the main method for killing drones is to use shotguns with high lethality. Other anti-drone methods, such as signal jamming, laser burning, and individual-carried shotguns, are not very versatile or portable, and their killing effect is not ideal. Therefore, there is currently no reliable anti-drone ammunition based on standard small-caliber firearms. Usually, it is necessary to carry an additional shotgun to achieve the purpose of anti-drone, which will affect the convenience of carrying it.

[0003] Therefore, there is an urgent need to design a special anti-drone ammunition based on standard small-caliber firearms to solve the aforementioned problems of versatility and portability in anti-drone operations. Utility Model Content

[0004] One objective of this invention is to provide a special anti-drone ammunition based on standard small-caliber firearms, solving the problems of versatility and portability in anti-drone applications.

[0005] Another objective of this invention is to provide a special anti-drone ammunition based on standard small-caliber firearms, thereby solving the problem that standard small-caliber firearms have low lethality against drones in anti-drone operations.

[0006] To address the technical challenges of versatility and portability in anti-drone applications mentioned in the background section, a special anti-drone ammunition based on standard small-caliber firearms is provided.

[0007] To achieve the above objectives, the specific technical solution of this utility model for an anti-drone special ammunition based on standard small-caliber firearms is as follows:

[0008] A special anti-drone ammunition based on standard small-caliber firearms includes a cartridge case and a projectile inserted into the cartridge case. The projectile includes a sabot and a wind cap connected to each other. The sabot is disposed inside the cartridge case and has a receiving cavity inside. The receiving cavity contains multiple projectile clusters, each of which includes multiple cylindrical projectiles. The cartridge case is also provided with a propulsion component for driving the projectile out of the cartridge case. The sabot is structured to split open after leaving the cartridge case, allowing the cylindrical projectiles to disperse.

[0009] Furthermore, the sidewall of the sabot is provided with a longitudinal groove. When the sabot leaves the cartridge case, it will be torn along the longitudinal groove by air force, so that the cylindrical projectile will disperse.

[0010] Furthermore, the cartridge case is cylindrical, and the sabot is a hollow symmetrical cylindrical structure with one end closed and the other end open, the opening facing the wind cap, and the cylindrical inner cavity of the sabot forming the receiving cavity.

[0011] Furthermore, the sabot and the receiving cavity have the same central axis as the cartridge case, and the central axis of the cylindrical projectile in each projectile bundle is arranged parallel to the central axis of the sabot.

[0012] Furthermore, the cylindrical projectiles in the projectile bundle are aligned and abutted against each other along the central axis, and the outer circumferential surface of the projectile bundle corresponds to the inner circumferential surface of the receiving cavity, so that the multiple projectile bundles are arranged abutting against each other along the central axis and are received in the receiving cavity.

[0013] Furthermore, adjacent projectile clusters are circumferentially staggered.

[0014] Furthermore, the outermost bundle of projectiles is housed in the receiving cavity, while the remaining portion extends into the wind cap.

[0015] Furthermore, the propulsion assembly includes a booster, which is disposed at the end of the cartridge case where the wind cap is not provided.

[0016] Furthermore, the propulsion assembly includes a seal disposed at the end of the sabot away from the wind cap, and the seal is capable of pushing the sabot away from the cartridge case under the action of the booster.

[0017] Furthermore, the end of the cartridge case where the booster is located has a receiving groove, the receiving groove is connected to the inner cavity of the cartridge case through a through hole, the booster is disposed in the receiving groove, and the booster includes a primer and a propellant.

[0018] The anti-drone ammunition of this invention, based on standard small-caliber firearms, has the following advantages:

[0019] 1) This anti-drone ammunition loads a cluster of projectiles into a cartridge case. The projectile cluster, under the action of the propulsion component and air resistance, will naturally disperse the projectiles to form a planar dispersion, thereby providing the main lethal force. This overcomes the defect that shotguns or other anti-drone equipment are often needed for the main kill in anti-drone operations. It solves the problem of versatility and portability faced by individual soldiers in anti-drone operations in the modern environment. In addition, this anti-drone ammunition based on standard small-caliber firearms uses cylindrical projectiles to replace the steel cylindrical ammunition in the existing technology. This allows the improved anti-drone ammunition based on standard small-caliber firearms to penetrate and damage the drone's rotor blades, or even penetrate the drone's plastic shell and damage the drone's internal circuits or important components such as batteries, thereby improving the lethality against drones and other low-altitude targets.

[0020] 2) This anti-drone special ammunition, which is based on standard small-caliber firearms, can provide a certain degree of denial in trenches or when facing unarmored targets. At the same time, the projectile cluster can play a certain role in breaching obstacles, cutting barbed wire and tripwires of tripwire mines, and can also clear booby traps and other explosives. The propulsion component can ensure stable gas-guided recoil firing when the loaded firearm is fired continuously. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0030] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a special anti-drone bullet based on standard small-caliber firearms. Example

[0031] This embodiment provides a special anti-drone ammunition based on standard small-caliber firearms, such as... Figures 1-3 As shown, it includes a cartridge case 1 and a projectile inserted into the cartridge case 1. The projectile includes a wind cap 2 and a sabot 5 connected to each other. The sabot 5 is disposed inside the cartridge case 1. The sabot 5 has a receiving cavity 51 inside, which contains multiple projectile clusters 4. Each projectile cluster 4 includes multiple cylindrical projectiles 411. The cartridge case 1 is also provided with a propulsion assembly for driving the projectile to leave the cartridge case 1. The sabot 5 is structured to break open after leaving the cartridge case 1, allowing the cylindrical projectiles 411 to disperse.

[0032] This anti-drone ammunition, designed for firing from standard small-caliber firearms, loads a projectile cluster 4 together within a sabot 5 inside the cartridge case 1. The projectile cluster 4, under the influence of the propulsion assembly and air resistance, causes the projectiles 411 to naturally disperse, forming a planar dispersion that provides primary lethality. Furthermore, this anti-drone ammunition, based on standard small-caliber firearms, replaces the existing steel cylindrical ammunition with a cylindrical projectile 411, overcoming the shortcomings of often requiring shotguns or other anti-drone equipment for primary lethality in anti-drone operations. It also addresses the challenge of individual soldiers in anti-drone warfare in the modern environment. The versatility and portability issues faced by drones have led to the development of improved anti-drone projectiles based on standard small-caliber firearms. These projectiles possess the penetration power to damage drone rotor blades, penetrate the drone's plastic shell, and harm internal circuitry or critical components such as batteries. This provides a degree of deterrence in trenches or against unarmored targets. Additionally, the projectile cluster can effectively breach obstacles, cutting through barbed wire and tripwires of tripwire mines, and clearing booby traps and other explosive devices. The propulsion system ensures stable gas-guided recoil firing during continuous firing of the loaded weapon.

[0033] Furthermore, the side wall of the sabot 5 is provided with a longitudinal groove. When the sabot 5 leaves the cartridge case 1, the sabot 5 will be torn along the longitudinal groove by the air force, so that the cylindrical projectile 411 will disperse.

[0034] Furthermore, the cartridge case 1 is cylindrical, and the sabot 5 is a hollow, symmetrical cylindrical structure closed at one end and open at the other, with the opening facing the wind cap 2. The cylindrical inner cavity of the sabot 5 forms a receiving cavity 51. The sabot 5 and the receiving cavity 51 have the same central axis as the cartridge case 1. The central axis of the cylindrical projectiles 411 in each projectile bundle 4 is parallel to the central axis of the sabot 5. In this embodiment, the axes of the multiple projectiles 411 are arranged parallel to each other, so that the projectiles 411 can disperse as little as possible after leaving the cartridge case 1, thereby further improving the lethality.

[0035] It should be noted that the shape of the projectile 411 can also be a hexagonal prism, fibrous, etc., mainly to improve its lethality and reduce its dispersion. In addition, it can also be replaced by spherical, conical, nail-shaped, etc., as in the prior art, without specific limitations here.

[0036] It should be noted that the wind cap 2 is mainly used to assemble the projectile cluster 4 into the cartridge case 1. On the other hand, in this embodiment, the wind cap 2 is located at the top of the cartridge case to block the projectile cluster 4, so that the ammunition can be fed smoothly into the chamber and avoid malfunctions such as jamming.

[0037] Optionally, in some embodiments, the wind cap 2 is made of polylactic acid (PLA), polystyrene (PS), polytetrafluoroethylene (PTFE) or other materials, and its shape is the same as that of the part of commonly used 0.8 mm ammunition. This allows anti-drone ammunition fired from standard small-caliber firearms to be filled into the 5.8 mm firearm, thereby enabling the ammunition to be fed smoothly into the chamber and avoiding malfunctions such as jamming.

[0038] Furthermore, the cylindrical projectiles 411 in the projectile bundle 4 are aligned and abut against each other along the central axis, and the outer circumferential surface of the projectile bundle 4 corresponds to the inner circumferential surface of the receiving cavity 51, so that multiple projectile bundles 4 are arranged abut against each other along the central axis and are received in the receiving cavity 51; adjacent projectile bundles 4 are staggered in the circumferential direction.

[0039] Furthermore, such as Figure 2 and Figure 3 As shown, the outermost projectile cluster 4 is housed in the receiving cavity 51, and the remaining part extends into the wind cap 2. The sabot 5 can leave the cartridge case 1 together with the projectile cluster 4 under the action of the propulsion component, and after leaving, it is torn and unfolded by the air force so that multiple projectiles 411 are scattered. The side wall of the sabot 5 is provided with a longitudinal slot. When the sabot 5 and the projectile cluster 4 leave the cartridge case 1, the sabot 5 will be torn and unfolded along the longitudinal slot by the air force so that multiple projectiles 411 are scattered.

[0040] The sabot 5 is a hollow, symmetrical structure used to accommodate the projectile cluster 4. The side wall has longitudinal slots. When the projectile 411 leaves the muzzle, the sabot 5 wall is torn and unfolded along the longitudinal slots by the air force, releasing the internal projectile cluster 4. Under the aerodynamic dispersion effect, the projectile cluster 4 will cause the projectile 411 to naturally disperse to form a surface dispersion, thereby causing damage to the target.

[0041] In this embodiment, the sabot 5 is made of copper or brass. In other embodiments, the sabot 5 may also be made of aluminum alloy or even plastic. No specific limitation is made here.

[0042] As a preferred embodiment, the above-mentioned sabot 5 can also be replaced by a copper basin in the prior art. Copper basins are common knowledge that can be understood by those skilled in the art. As for how to use a copper basin to install the projectile cluster 4, it is also a conventional technical means. Therefore, this embodiment will not make any further details or limitations.

[0043] Furthermore, the propulsion assembly includes a booster 3 and a seal 6. The booster 3 is located at the end of the cartridge case 1 where the wind cap 2 is not provided. The propulsion assembly also includes a seal 6, which is located at the end of the sabot 5 away from the wind cap 2. The seal 6 can push the sabot 5 away from the cartridge case 1 under the action of the booster 3.

[0044] Furthermore, the seal 6 is located at the end of the sabot 5 away from the wind cap 2, and the seal 6 can push the projectile cluster 4 away from the cartridge case 1 under the action of the propulsion assembly.

[0045] In this embodiment, the seal 6 is located at the rear of the sabot 5 and is used to withstand the gas pressure of the propulsion assembly and to close the gas, thereby pushing the sabot 5, the projectile cluster 4, and the wind cap 2 forward in a straight line and increasing the kinetic energy of the projectile cluster 4 to achieve the launch of the ammunition and further improve its lethality.

[0046] In some embodiments, the sealing element 6 can be replaced by a copper bowl in the prior art, and the felt pad is common knowledge that can be understood by those skilled in the art. As for how to use the felt pad to install the projectile cluster 4, it is also a conventional technical means. Therefore, this embodiment will not make any further details or limitations.

[0047] Optionally, in some embodiments, the seal 6 is made of a flame-retardant material to withstand the gas pressure and gas tightness of the propulsion assembly.

[0048] In a preferred embodiment, the aforementioned booster 3 includes a primer and a propellant, both of which are installed in the receiving groove 11. In use, the primer is ignited, thereby igniting the propellant, which then burns and generates a large amount of gunpowder gas, thereby enabling the launch of the ammunition.

[0049] Furthermore, the projectile cluster 4 includes multiple clustering parts 41, which are arranged sequentially along the axial direction of the projectile casing 1, and each clustering part 41 is rotated and offset from the adjacent clustering part 41.

[0050] Furthermore, each cluster 41 includes a plurality of projectiles 411, each projectile 411 being parallel to each other and arranged in a circumferential direction.

[0051] Understandably, during installation, the projectile cluster 4 can be housed inside the sabot 5, providing primary lethality. After firing, it disperses to kill targets. Furthermore, it should be noted that the projectile 411 is cylindrical in shape, unlike the existing steel ball bearing structure. The main purpose is that the design of the projectile 411 balances ammunition dispersion and installation difficulty. Since existing steel cylindrical structures are generally easy to assemble, the installation difficulty for workers is low. Therefore, while facilitating installation and fabrication, it also facilitates mass production. However, due to… The characteristics of ball bearings result in a large dispersion area of ​​the ammunition after firing. In other words, existing anti-drone ammunition based on standard small-caliber firearms, which uses steel ball bearings as the main source of damage, mainly aims to increase the dispersion area of ​​the ammunition. However, it usually suffers from insufficient lethality. Using the 411 projectile as the main source of damage can minimize the dispersion area, thereby concentrating the lethality and improving the killing effect. In addition, since the cylindrical structure usually does not present significant processing or installation difficulties, it is also easy to achieve mass production.

[0052] In one preferred embodiment, the projectile 411 is made of hard materials such as steel, lead, and cemented carbide;

[0053] In this embodiment, the bullet bundle 4 is cylindrical in shape. In addition, the bundle portion 41 can also form an ellipsoidal or fibrous bullet bundle 4, which is not specifically limited here.

[0054] Furthermore, the end of the cartridge case 1 where the propulsion component is located has a receiving groove 11. The receiving groove 11 is connected to the interior of the cartridge case 1 through a through hole. The propulsion component is located in the receiving groove 11 and is connected to it through the through hole.

[0055] It is understood that the anti-drone ammunition based on standard small-caliber firearms in this embodiment typically relies on standard small-caliber firearms for firing. Furthermore, this firearm uses the aforementioned anti-drone ammunition based on standard small-caliber firearms as ammunition, ensuring that the destructive force after firing can penetrate the drone's outer shell and even damage its internal circuitry or important components such as the battery. Moreover, the residue from the anti-drone ammunition after firing will not clog the firearm's chamber or gas tube, thus preventing damage or unusability. In addition, this firearm is easy to store and transport, not easily damaged, and does not significantly increase logistical support. During anti-drone operations, soldiers do not need to carry both rifles and shotguns (rifles for killing soldiers, shotguns for killing drones); they only need to carry the small-caliber firearm provided in this embodiment capable of firing the dedicated ammunition. This overcomes the drawback of often requiring shotguns for primary damage in anti-drone operations, thus improving convenience.

[0056] Optionally, the aforementioned firearms can be designed with a standard 5.8mm caliber firearm structure. In addition, it should be noted that, in view of the versatility of the aforementioned special ammunition, the aforementioned firearms can be pistols, rifles, submachine guns or light machine guns, including but not limited to smoothbore shotguns or rifled guns, etc., without specific limitations.

[0057] Furthermore, those skilled in the art can refer to the following steps when using the firearm based on the anti-drone ammunition fired from a standard small-caliber firearm: First, when the anti-drone ammunition is fired from a standard small-caliber firearm, the primer is ignited, igniting the propellant, which burns and produces a large amount of propellant gas; the sealing member 6 moves forward under the push of the propellant gas, simultaneously pushing the sabot 5, the wind cap 2, and the projectile cluster 4 forward together; after the projectile 411 leaves the muzzle, the wall of the sabot 5 is torn along the longitudinal groove and unfolded by the air force, releasing the internal projectile cluster 4. The projectile cluster 4 naturally disperses under the action of aerodynamic dispersion, forming a planar dispersion that damages the target. Example

[0058] The foamed board provided in this embodiment is basically the same as the anti-drone bullet based on standard small-caliber firearms in the embodiment. The difference is that the projectile cluster 4 in this embodiment also includes a penetrating part 42, such as... Figure 4 and Figure 5 As shown, the penetrating part 42 is disposed inside the wind cap 2, so that the cluster part 41 and the penetrating part 42 can completely fill the receiving cavity 51 of the wind cap 2 and the sabot 5, thereby maximizing space utilization. In addition, the end of the penetrating part 42 near the wind cap 2 is set with a sharp structure, so that the projectile cluster 4 can achieve the purpose of penetration and penetration by utilizing the sharp structure of the penetrating part 42 after it disperses. In practical applications, the role of the penetrating part 42 can also be reflected in close-range anti-personnel, thereby further improving the application scenarios of anti-drone special ammunition based on standard small-caliber firearms.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
