[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] Please refer to the attached Figure 1 To Attachment Figure 5 The present invention describes a special anti-UAV bullet based on the launch of a standard small-caliber firearm.

[0023] Embodiment 1: This embodiment provides a special anti-UAV bullet based on a standard small-caliber firearm, such as Figure 1-Figure 3 As shown, it includes a cartridge case 1 and a bullet inserted on the cartridge case 1, the bullet includes a wind cap 2 and a sabot 5 connected to each other, the sabot 5 is arranged in the cartridge case 1, the interior of the sabot 5 is provided with a receiving cavity 51, and the receiving cavity 51 accommodates a plurality of projectile clusters 4, each projectile cluster 4 includes a plurality of cylindrical projectiles 411, and a propulsion assembly is also provided on the cartridge case 1 for driving the bullet to leave the cartridge case 1, and the structure of the sabot 5 is arranged to be able to split after leaving the cartridge case 1 to allow the cylindrical projectiles 411 to disperse.

[0024] The special anti-UAV bullet based on the standard small-caliber firearm is loaded with a pellet cluster 4 in a cartridge case 5, and the pellet cluster 4 is naturally dispersed by the propulsion assembly and air resistance to form a surface dispersion, thereby providing the main lethality. In addition, the special anti-UAV bullet based on the standard small-caliber firearm replaces the steel cylindrical ammunition in the prior art with a cylindrical pellet 411, thereby overcoming the defect that a shotgun or other anti-UAV equipment is often required to carry out the main lethality in anti-UAV operations, and solving the problem that a single soldier in a contemporary combat environment cannot easily cause serious damage. The versatility and portability issues faced in anti-UAV operations have made it possible for the improved anti-UAV special bullets based on standard small-caliber firearms to have penetration power that can damage the UAV rotor blades, or further penetrate the UAV's plastic shell, and damage important components such as the UAV's internal circuit or battery, causing a certain denial effect in trenches or facing unarmored targets. At the same time, the projectile cluster 4 can play a certain role in clearing obstacles, cutting the wire mesh and the tripping rope of the tripping mine, and clearing explosives such as booby traps. The role of the propulsion component can ensure stable gas-guided recoil shooting when the loaded gun is fired continuously.

[0025] Furthermore, the side wall of the cartridge case 5 is provided with a longitudinal slot. When the cartridge case 5 leaves the cartridge case 1, the cartridge case 5 will be torn along the longitudinal slot by the air force, so that the cylindrical projectile 411 is scattered.

[0026] Further, the cartridge case 1 is set to be cylindrical, the sabot 5 is a hollow symmetrical cylindrical structure with one end closed and the other end open, 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, and the central axis of the cylindrical projectile 411 in each projectile cluster 4 is arranged 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 be dispersed as little as possible after leaving the cartridge case 1, thereby further improving the lethality.

[0027] It should be noted that the shape of the projectile 411 can also be hexagonal, fibrous, etc., mainly for the purpose of increasing lethality and reducing dispersion. In addition, it can also be replaced by a spherical, conical, nail-shaped, etc. in the prior art, which is not specifically limited here.

[0028] It should be noted that the wind cap 2 is mainly used to assemble the pellet cluster 4 into the cartridge case 1. On the other hand, in the present embodiment, the wind cap 2 is located at the top of the cartridge case to block the pellet cluster 4 so that the ammunition can be smoothly fed into the chamber to avoid jamming and other malfunctions.

[0029] Optionally, in some embodiments, the hood 2 is made of polylactic acid (PLA), polystyrene (PS), polytetrafluoroethylene (PTFE) or other materials, and its appearance is the same as that of the commonly used .mm ammunition, so that the special anti-UAV bullets fired by standard small-caliber firearms can be filled into 5.8mm firearms, so that the ammunition can be smoothly fed into the chamber to avoid malfunctions such as jamming.

[0030] Furthermore, the cylindrical projectiles 411 in the projectile cluster 4 are aligned in the direction of the central axis and arranged against each other, and the outer circumferential surface of the projectile cluster 4 corresponds to the inner circumferential surface of the accommodating cavity 51, so that multiple projectile clusters 4 are arranged in sequence along the central axis and accommodated in the accommodating cavity 51; adjacent projectile clusters 4 are staggered in the circumferential direction.

[0031] Furthermore, if Figure 2 and Figure 3 As shown, the outermost part of the pellet cluster 4 is accommodated in the accommodating cavity 51, and the remaining part extends into the wind cap 2. The buttress 5 can leave the cartridge case 1 together with the pellet cluster 4 under the action of the propulsion assembly, and after leaving, it is torn and unfolded by the action of air, so that the multiple pellets 411 are scattered; the side wall of the buttress 5 is provided with a longitudinal groove. When the buttress 5 and the pellet cluster 4 leave the cartridge case 1, the buttress 5 will be torn and unfolded along the longitudinal groove by the action of air, so that the multiple pellets 411 are scattered.

[0032] The cartridge case 5 is a hollow symmetrical structure for accommodating the pellet cluster 4, and has a longitudinal groove on the side wall. When the pellet 411 leaves the muzzle, the wall of the cartridge case 5 is torn and unfolded along the longitudinal groove by the force of air, releasing the pellet cluster 4 inside; the pellet cluster 4 will naturally disperse the pellet 411 under the action of aerodynamic divergence to form a surface dispersion, thereby causing damage to the target.

[0033] In the present embodiment, the cartridge case 5 is made of copper or brass. In other embodiments, the cartridge case 5 may also be made of aluminum alloy or even plastic, which is not specifically limited here.

[0034] As a preferred embodiment, the above-mentioned cartridge case 5 can also be replaced by a copper bowl in the prior art, and the copper bowl is common knowledge that can be understood by those skilled in the art. As for how to use the copper bowl to realize the installation of the projectile cluster 4, it is also a conventional technical means. Therefore, this embodiment does not make additional elaboration and limitation.

[0035] Furthermore, the propulsion assembly includes a booster 3 and a sealing member 6. The propulsion assembly includes the booster 3, which is arranged at the end of the cartridge case 1 where the wind cap 2 is not provided. The propulsion assembly also includes a sealing member 6, which is arranged at the end of the cartridge case 5 away from the wind cap 2. The sealing member 6 can push the cartridge case 5 away from the wind cap 2 under the action of the booster 3.

[0036] Furthermore, the sealing member 6 is arranged at one end of the cartridge case 5 away from the wind cap 2 , and the sealing member 6 can push the projectile cluster 4 to leave the cartridge case 1 under the action of the propulsion assembly.

[0037] In this embodiment, the seal 6 is located at the rear of the cartridge case 5 and is used to withstand the gas pressure and airtightness of the propulsion assembly, thereby pushing the cartridge case 5, the pellet cluster 4, and the wind cap 2 to move forward in a straight line, and increasing the kinetic energy of the pellet cluster 4, thereby achieving the launch of the ammunition and further improving the lethality.

[0038] In some embodiments, the above-mentioned seal 6 can also 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 achieve the installation of the projectile cluster 4, it is also a conventional technical means. Therefore, this embodiment does not make additional elaboration and limitation.

[0039] Optionally, in some embodiments, the seal 6 is made of flame-retardant material to withstand the gas pressure and airtightness of the propulsion assembly.

[0040] As a preferred embodiment, the booster 3 includes a primer and a propellant, wherein both the primer and the propellant are installed in the receiving groove 11. When in use, the primer will be fired to ignite the propellant, and the propellant will burn and generate a large amount of gunpowder gas, thereby realizing the firing of the ammunition.

[0041] Furthermore, the projectile cluster 4 includes a plurality of clustering portions 41 , which are arranged in sequence along the axial direction of the cartridge case 1 , and each clustering portion 41 is arranged in a rotationally staggered manner with respect to an adjacent clustering portion 41 .

[0042] Furthermore, each clustering portion 41 includes a plurality of pellets 411 , and each pellet 411 is parallel to each other and arranged in a circumferential direction.

[0043] It is understandable that during installation, the pellet cluster 4 can be installed inside the cartridge case 5 to provide the main lethality, and form a dispersion after firing to kill the target. In addition, it should be noted that the shape of the pellet 411 is set to be cylindrical, which is different from the steel ball structure of the prior art. The main purpose is that the design of the pellet 411 is a structure that balances the dispersion of ammunition and the difficulty of installation. Since the existing steel cylindrical structure is usually easy to assemble, the installation difficulty of the staff is relatively low. Therefore, on the basis of facilitating the installation and production of the staff, it is also easy to achieve mass production. However, due to Due to the characteristics of the ball bearings, the dispersion area of ​​the ammunition after firing is larger. That is to say, the design of anti-UAV special bullets based on standard small-caliber firearms in the prior art using steel balls as the main killing source is more to increase the dispersion area of ​​the ammunition. However, there is usually a defect of insufficient lethality. Using projectile 411 as the main killing source can reduce the dispersion area as much as possible, thereby concentrating the lethality and achieving the purpose of improving the killing effect. In addition, since the cylindrical structure usually does not cause greater processing and installation difficulties, it is also easy to achieve mass production.

[0044] As a preferred embodiment, the projectile 411 is made of hard materials such as steel, lead, and hard alloy; In this embodiment, the pellet cluster 4 is columnar in shape. In addition, the cluster portion 41 may also form an ellipsoidal or fibrous pellet cluster 4, which is not specifically limited here.

[0045] Furthermore, a receiving groove 11 is provided at one end of the cartridge case 1 on which the propulsion assembly is provided. The receiving groove 11 is communicated with the interior of the cartridge case 1 through a through hole, and the propulsion assembly is arranged in the receiving groove 11 and communicated through the through hole.

[0046] It can be understood that the special anti-UAV bullet based on the standard small-caliber firearm of the present embodiment is usually launched by the standard lower-caliber firearm. Further, the firearm uses the above-mentioned special anti-UAV bullet based on the standard small-caliber firearm as ammunition, which ensures that the lethality after the launch can penetrate the shell of the UAV, and even damage the internal circuit or battery and other important components of the UAV, and the residue of the special anti-UAV bullet based on the standard small-caliber firearm after the launch will not block the gun barrel and gas duct of the firearm, thereby causing the problem of damage to the firearm or unusable. In addition, the firearm also has the advantages of being easy to store and transport, not easy to be damaged, and not increasing the pressure of logistics support too much. In the process of anti-UAV operations, soldiers do not need to adopt the mode of carrying rifles and shotguns at the same time (rifles are used to kill soldiers, and shotguns are used to kill UAVs). They only need to carry the small-caliber firearms provided in the present embodiment that can launch special bullets, which overcomes the defect that shotguns are often required for main killing in anti-UAV operations, and achieves the purpose of improving convenience.

[0047] Optionally, the firearm can be designed to have a standard firearm structure with a caliber of 5.8 mm. In addition, it should be noted that, in view of the versatility of the above-mentioned special bullets, the firearm can be a pistol, a rifle, a submachine gun or a light machine gun, including but not limited to a smoothbore shotgun or a rifled gun, etc., without specific limitation herein.

[0048] Further, those skilled in the art can refer to the following steps when using the above-mentioned firearms based on standard small-caliber firearms to launch special anti-UAV bullets: First, when launching the special anti-UAV bullets based on standard small-caliber firearms, the primer is fired, the propellant is ignited, the propellant burns and produces a large amount of gunpowder gas; the seal 6 moves forward under the impetus of the gunpowder gas, and at the same time pushes the buttstock 5, the wind cap 2 and the projectile cluster 4 to move forward together; when the projectile 411 leaves the muzzle, the wall of the buttstock 5 is torn and unfolded along the longitudinal groove by the force of air, releasing the internal projectile cluster 4. The projectile cluster 4 naturally disperses under the action of aerodynamic divergence, forming a surface dispersion, causing damage to the target.

[0049] Embodiment 2: The foamed plate provided in this embodiment is basically the same as the anti-UAV special bullet based on the standard small-caliber firearm in the embodiment, except that the bullet cluster 4 in this embodiment further includes a penetration portion 42, such as Figure 4 and Figure 5 As shown, the penetration portion 42 is arranged inside the hood 2, so that the clustering portion 41 and the penetration portion 42 can completely fill the accommodating cavity 51 of the hood 2 and the cartridge case 5, thereby maximizing the space utilization. In addition, the end of the penetration portion 42 close to the hood 2 is set as a sharp structure, so that the projectile cluster 4 can use the sharp structure of the penetration portion 42 to achieve the purpose of penetration after dispersion. In actual applications, the role of the penetration portion 42 can also be reflected in close-range anti-personnel combat applications, thereby further improving the use scenarios of anti-UAV special bullets based on standard small-caliber firearms.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
