Description

Technical Field

[0001] The invention relates to the fields of military and shooting sports, and in particular to an anti-UAV bullet. Background Art

[0002] The performance of a bullet is directly related to the accuracy and power of a shot. Traditional bullet design often focuses on the combustion efficiency of gunpowder and the flight stability of the bullet head. However, in some special application scenarios, when the bullet is required to produce additional destructive effects after hitting the target or to achieve specific functions such as explosion dispersion, deceleration, entanglement, etc. to deal with non-traditional threats such as drones, traditional bullet design is inadequate. Although ordinary rifle bullets have a long range, they cannot achieve the purpose of anti-drone; although shotguns can shoot down drones, they have a short range.

[0003] For example, patent number CN108759590A describes an explosive reverse thrust integral bullet and its firing gun, which sets multiple small explosion chambers in the bullet head. When the bullet hits the target, these small explosion chambers will be detonated simultaneously or sequentially to generate fragments or shock waves, thereby enhancing the destructive power to the target. However, although this design improves the destructive effect, it also brings problems such as complex structure, high manufacturing cost and low gunpowder utilization efficiency.

[0004] In addition, patent number CN630945B introduces a bullet with a spiral deceleration device, which increases the mass and shape of the bullet head to generate greater resistance when hitting the target, thereby slowing down the penetration speed of the bullet and improving the accuracy of shooting. However, this design increases the mass of the bullet head while also increasing the flight resistance of the bullet, affecting the range and flight stability of the bullet.

[0005] In summary, the bullet design in the prior art often has problems such as complex structure, high manufacturing cost, low gunpowder utilization, and influence on bullet range and flight stability when pursuing specific functions. Therefore, it is necessary to design a new bullet structure to overcome the deficiencies in the prior art. Summary of the invention

[0006] The present invention aims to provide a new bullet structure, which not only has the shooting accuracy and power of traditional bullets, but also can realize specific functions such as explosion dispersion, deceleration, etc., while overcoming the problems of complex structure, high manufacturing cost and low gunpowder utilization rate in the prior art, and solves the problem of long effective range in anti-UAV shooting, and can also shoot down UAVs at a long distance.

[0011] Furthermore, the silk thread passes through the gunpowder chamber and is connected to the sealing cover via the hollow tube 1 and the hollow tube 2.

[0012] Furthermore, the bullet head is a hollow bullet head bag, and the end of the bullet head bag is equipped with a matching cover.

[0013] Furthermore, the gunpowder chamber of the ejection power structure can be replaced with a spring, a spring is arranged in the bullet head bag, one end of the silk thread is fixedly connected to the inner wall of the bullet head bag, and the other end passes through the spring and is connected to the cover.

[0014] Furthermore, a hollow tube 2 is integrally formed in the middle of the cover, and a hollow tube 1 is integrally formed in the middle of the powder chamber. Both hollow tube 1 and hollow tube 2 are hollow tubular columns with matching tube diameters. Hollow tube 1 is connected to a central through hole at the wall of the powder chamber. The central through hole is used for threading silk thread, and hollow tube 1 is used to protect the silk thread passing through the powder chamber.

[0015] Furthermore, one end of the silk thread is also connected to a drag parachute, which is arranged between the cover and the gunpowder chamber.

[0016] Furthermore, the bullet shell is nested and connected with the rear end of the bullet head.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an anti-UAV bullet, including a bullet head and a bullet shell. The bullet head is composed of a silk thread, a spring, a gunpowder cavity, a fire transfer agent, an ignition agent, a hollow tube 1, a hollow tube 2 and a cap. One end of the bullet head is equipped with a cap, and the other end is connected to a winding silk thread inside, and the silk thread is connected to the cap. A section of spring is arranged in the bullet head, and the silk thread passes through the spring. A gunpowder cavity is arranged on one side of the spring, and a hollow tube 1 is connected to the cavity wall of the gunpowder cavity. A hollow tube 2 is connected to the cap, and the outer tube diameter of the hollow tube 2 is matched with the inner tube diameter of the hollow tube 1. The cap is inserted into the hollow tube 1 through the hollow tube 2 to realize the assembly with the bullet head. The gunpowder cavity is filled with gunpowder, and one side of the gunpowder is filled with a fire transfer agent, and one side of the fire transfer agent is filled with an ignition agent. The inside of the bullet shell is filled with gunpowder, and the end of the bullet shell is provided with a primer for igniting the gunpowder.

[0026] The silk thread passes through the gunpowder cavity and is connected to the cover through the hollow tube 1 and the hollow tube 2 to achieve the fixation of the silk thread and the sealing of the gunpowder cavity. The bullet head is a hollow bullet head capsule, and the end of the bullet head capsule is equipped with a matching cover to reduce the mass of the bullet head and reduce the flight resistance. The bullet head capsule stores the silk thread, and a section of spring is arranged outside the silk thread. The spring serves as the ejection power structure of the bullet head, and the gunpowder power supply is realized through the explosion of the gunpowder cavity. The gunpowder cavity is arranged between the silk thread and the cover, and an ignition agent is arranged on the cover. One side of the ignition agent contacts the ignition agent filled with the ignition agent, and the other side of the ignition agent contacts the gunpowder filled with the gunpowder cavity to realize the sequential detonation of the gunpowder. The middle part of the cover is integrally formed with a hollow tube 2, and the middle part of the gunpowder chamber is integrally formed with a hollow tube 1. Both hollow tubes 1 and 2 are hollow tubular columns with matching diameters. Hollow tube 1 is connected to a central through hole at the wall of the gunpowder chamber. The central through hole is used for threading the silk thread, and hollow tube 1 is used to protect the silk thread passing through the gunpowder chamber. A drag parachute is also connected to one end of the silk thread. The drag parachute is arranged between the cover and the spring to generate greater resistance when the bullet hits the target and slow down the penetration speed of the bullet. The bullet shell is nested and connected to the rear end of the bullet head to achieve the fixation and sealing of the bullet head and the bullet shell.

[0027] Among them, the bullet head 1 has a unique structural feature, including a silk thread 101, a spring 102, a gunpowder chamber 103, a fire transfer agent 104, an ignition agent 105, a hollow tube 106, a hollow tube 2 107 and a cap 108. The silk thread 101 is a slender linear body, which is wound and arranged inside the bullet head 1, one end is connected to the cap 108, and the other end passes through the gunpowder chamber 103 and the spring 102, and is used to transmit power when the gunpowder explodes, so that the cap 108 and other parts of the bullet head 1 are separated or produce a specific movement. The spring 102 is a section of an elastic element, which is arranged outside the silk thread 101 and serves as a pop-up power structure of the bullet head 1. When the gunpowder in the gunpowder chamber 103 explodes, the spring 102 will be impacted and release energy, pushing the cap 108 and other parts of the bullet head 1 to produce movement. The gunpowder chamber 103 is a cavity for storing gunpowder 201, which is arranged on one side of the spring 102. A hollow tube 106 is connected to the cavity wall of the gunpowder chamber 103 for transmitting the ignition signal and the gas generated by the gunpowder explosion. The ignition agent 104 is a flammable substance, which is filled on one side of the gunpowder 201 in the gunpowder chamber 103, and is used to receive the ignition signal and transmit it to the gunpowder 201, causing the gunpowder explosion. The ignition agent 105 is a substance that can quickly ignite the ignition agent 104, which is filled on one side of the ignition agent 104, and ignites the ignition agent 104 by receiving an external ignition signal such as the detonation of the primer 202. The hollow tube 106 and the hollow tube 2 107 are tubular cylinders arranged on the gunpowder chamber 103 and the cover 108, respectively, and the diameters of the two are matched, and are used to connect the cover 108 and other parts of the bullet head 1, and protect the silk thread 101 passing through the gunpowder chamber 103. The cover 108 is a component for closing one end of the bullet head 1, and is connected with a hollow tube 2 107. The cover 108 is inserted into the hollow tube 1 106 through the hollow tube 2 107 to realize assembly with the bullet head 1 . Meanwhile, an ignition agent 105 and a structure for connecting the silk thread 101 are also provided on the cover 108 .

[0028] In terms of connection, the thread 101 passes through the gunpowder chamber 103, the spring 102, the hollow tube 106, the hollow tube 107, and finally connects with the cover 108. The spring 102 is sleeved on the outside of the thread 101 and fixed at an appropriate position between the gunpowder chamber 103 and the cover 108. The gunpowder chamber 103 is connected to the hollow tube 107 on the cover 108 through the hollow tube 106, forming a gas channel when the gunpowder explodes. The ignition agent 104 and the ignition agent 105 are filled in the gunpowder chamber 103 and on the cover 108 respectively, and sequential detonation is achieved through the ignition signal.

[0029] The bullet shell 2 is another important component of the bullet of the present invention. It is filled with gunpowder 201 and has a primer 202 at the end to ignite the gunpowder 201. The gunpowder 201 is the main substance for the bullet to produce explosive power and is filled inside the bullet shell 2. When the primer 202 is ignited, the gunpowder 201 will burn quickly and generate a large amount of gas and heat, pushing the bullet head 1 forward. The primer 202 is a device for igniting the gunpowder 201 and is arranged at the end of the bullet shell 2. When the bullet is fired, the primer 202 will receive the firing signal and generate sparks or high-temperature gas to ignite the gunpowder 201.

[0030] In terms of connection, the bullet shell 2 is nested and connected with the rear end of the bullet head 1 to form a complete bullet structure. The gunpowder 201 filled in the bullet shell 2 is ignited by the primer 202 to push the bullet head 1 forward.

[0031] The bullet structure of this embodiment is mainly composed of a bullet head 1 and a bullet shell 2, and its overall working method is as follows:

[0032] 1. Filling and preparation

[0033] The inside of the bullet shell 2 is pre-filled with gunpowder 201, and a primer 202 is installed at its end. Inside the bullet head 1, the gunpowder chamber 103 is also filled with gunpowder 201, and the ignition agent 104 and the ignition agent 105 are respectively filled on one side of the gunpowder 201 and on the cover 108. The silk thread 101 passes through the gunpowder chamber 103 and the spring 102, and is connected to the cover 108 through the hollow tube 106 and the hollow tube 2 107.

[0034] 2. Firing Process

[0035] When the bullet is fired by the firearm, the firing pin of the firearm will hit the primer 202, causing the primer 202 to produce sparks or high-temperature gas. The sparks or high-temperature gas of the primer 202 ignite the gunpowder 201 inside the bullet shell 2, and the gunpowder 201 burns rapidly and produces a large amount of high-pressure gas. At the same time, the detonation signal of the primer 202 may also be transmitted in some way, such as through the firing mechanism of the firearm, to ignite the igniter 105 in the bullet head 1. After the igniter 105 is ignited, the ignition agent 104 is quickly ignited, and the ignition agent 104 then transmits the flame to the gunpowder 201 in the gunpowder chamber 103.

[0036] 3. Gunpowder Explosion and Bullet Movement

[0037] The high pressure gas generated by the explosion of the gunpowder 201 inside the bullet shell 2 pushes the bullet head 1 forward. At the same time, the gunpowder 201 in the gunpowder chamber 103 also explodes, but due to the small amount of gunpowder and the limitation of the cover 108 and the hollow tube structure, the explosion mainly produces an inward impact force. This inward impact force compresses the spring 102, and the cover 108 is ejected and separated under the combined effect of the explosion impact and the energy released by the spring 102, and the silk thread 101 is pulled out at the same time.

[0038] In the implementation of the anti-UAV function of this embodiment, after the bullet is fired out of the barrel, the ignition agent in the bullet capsule is ignited, and then the ignition agent is ignited, and the ignition agent ignites the gunpowder in the bullet capsule. The thrust generated by the explosion of the gunpowder ejects the cover at the rear end of the bullet capsule, and at the same time, the cover pulls the silk thread in the bullet capsule backwards for a distance. The bullet continues to move forward with the silk thread. After the bullet hits the drone, the silk thread, under the action of inertia, wraps around the propeller blades of the drone, causing the propeller blades of the drone to stop rotating, thereby losing the drone's ability to fly.

[0039] Embodiment 2

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an anti-UAV bullet, which is mainly composed of a bullet head 1 and a bullet shell 2, wherein the bullet head 1 contains a series of precisely designed parts to achieve specific functions. The following is a detailed description of the working principle of the device:

[0041] 1. Initial State

[0042] Inside the bullet head 1, the gunpowder chamber 103 is filled with gunpowder 201, the ignition agent 104 is placed next to the gunpowder 201, and the ignition agent 105 is located in the cover 108, close to one end of the ignition agent 104. The wire 101 passes through the gunpowder chamber 103 and the spring 102, and is connected to the cover 108 through the hollow tube 106 and the hollow tube 2 107, maintaining a certain preload. The spring 102 is in a compressed state, providing energy reserve for the pop-up of the cover 108.

[0043] 2. Firing and Ignition

[0044] When the firearm is fired, the firing pin hits the primer 202, and the primer 202 generates sparks to ignite the gunpowder 201 in the bullet shell 2, generating high-pressure gas to push the bullet forward. At the same time, the detonation signal of the primer 202 or the signal transmitted by the firing mechanism of the firearm triggers the ignition agent 105 in the bullet head 1, and the ignition agent 105 quickly ignites the ignition agent 104.

[0045] 3. Gunpowder Explosion and Energy Release

[0046] After the ignition transfer agent 104 is ignited, the flame spreads rapidly to the gunpowder 201 in the gunpowder chamber 103, causing the gunpowder explosion. The high temperature and high pressure gas produced by the gunpowder explosion expands rapidly in the gunpowder chamber 103, producing a strong impact force to the cap 108 and the spring 102. Under the combined effect of the impact force of the gunpowder explosion and the energy released by the spring 102, the cap 108 pops up rapidly along the hollow tube 106 and the hollow tube 2 107. Meanwhile, the silk thread 101 plays a role of guiding, stabilizing or enhancing the pop-up effect in the process in which the cap 108 pops up and pulls out the silk thread. After the cap 108 pops up and pulls out the silk thread, the remainder of the bullet head 1 includes that the structures such as the gunpowder chamber 103 and the spring 102 continue to be promoted by the high pressure gas produced by the gunpowder explosion in the bullet shell 2, and flies forward until hitting the target and the silk thread wraps around the target under the effect of inertia.

[0047] In summary, the novel bullet structure of the present invention realizes a unique working principle and function through careful design and precise matching of parts. Its unique capping and ejection mechanism adds extra striking effect and flexibility to the bullet, thus improving the actual combat performance and application range of the bullet.

[0048] Embodiment 3

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a basic bullet structure, wherein the bullet head 1 is equipped with components such as a thread 101, a spring 102, and a gunpowder chamber 103, and is connected to a cover 108 through a hollow tube 106 and a hollow tube 2 107. The bullet shell 2 is filled with gunpowder 201, and a primer 202 is installed at the bottom. When firing, the primer 202 detonates the gunpowder 201, pushing the bullet head 1 forward, and the gunpowder chamber 103 in the bullet head 1 will also explode, and the explosion mainly acts on the cover 108, causing the cover 108 to pop out and pull out the thread 101.

[0050] Embodiment 4

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a bullet structure with a delayed explosion function, and a delayed fuse 109 is added on the basis of the third embodiment. The delayed fuse 109 is arranged between the gunpowder chamber 103 and the igniter 105, and is used to control the explosion time of the gunpowder 201 in the gunpowder chamber 103. When the bullet is fired, the primer 202 first ignites the gunpowder 201 in the bullet shell 2, pushing the bullet as a whole to fly forward. After the preset delay time, the delayed fuse 109 ignites the igniter 105, and then ignites the ignition agent 104 and the gunpowder 201 in the gunpowder chamber 103, achieving a delayed explosion effect. This design can be used for specific tactical needs, such as attacking enemies behind bunkers or destroying enemy equipment.

[0052] Embodiment 5

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the present embodiment provides a bullet structure with a front air inlet, and the present embodiment adds an air inlet at the front end of the bullet head 1 for introducing external air during the bullet flight. The air inlet can be designed as a small hole, a gap or an adjustable opening and closing structure to adapt to different flight speeds and air pressure conditions. In order to enhance the air intake effect and control the influence of airflow on the movement of the bullet, a pneumatic piston can be arranged behind the air inlet. The pneumatic piston is made of lightweight material and can move and change the air pressure distribution inside the bullet head 1 under the action of airflow, thereby affecting the flight stability and trajectory of the bullet. The design of the air inlet and the pneumatic piston needs to comprehensively consider the factors such as the flight speed, air pressure change, and target distance of the bullet to ensure that the bullet can remain stable during flight and accurately hit the target and entangle the target by pulling out the silk thread 101 using airflow.

[0054] Embodiment 6

[0055] like Figure 1 , Figure 2 As shown, in this embodiment, the structure of the hollow tube 107 is modified, and the hollow tube 107 is replaced with a solid cylinder. The silk thread is directly connected to the solid cylinder through the hollow tube 106. Because the solid cylinder is integrally formed with the cover 108, the hollow tube 106 is also a hollow tube structure with a double-layer tube wall. The solid cylinder is inserted into the tube cavity of the hollow tube 106. This method can better protect the silk thread.

[0056] The above shows and describes the basic principles and main features of the present invention and the advantages of the invention.
