Description

Technical Field

[0001] The invention relates to the field of non-lethal munitions, and in particular to a novel deployable electrode radio munition. Background Technology

[0002] Electroshock weapons are non-lethal weapons that release high-voltage pulses of a specific frequency onto a target, interfering with the body's normal bioelectrical transmission and primarily affecting skeletal muscles and the nervous system. By outputting high-voltage pulses of a specific frequency, they cause the target's muscles to contract or twitch uncontrollably, rendering the target incapacitated within seconds without causing fatal damage, thus achieving a non-lethal subjugation.

[0003] Shotguns are widely used weapons in counter-terrorism and riot control, with large numbers in service, high reliability, and a wide variety of compatible non-lethal ammunition, making them an ideal riot control platform. However, due to the size limitations of their ammunition, although domestic and international efforts have been focused on developing corresponding radio-guided munitions, their effectiveness has remained less than ideal.

[0004] Currently, the most widely used non-lethal stun weapons are wired stun guns (such as the Taser series) and radio-guided stun guns. The main drawbacks of wired stun guns are: firstly, their effective range is short, generally 7-9 meters; secondly, the number of shots is limited, generally no more than three, resulting in poor multi-target engagement capability. The main disadvantage of traditional radio-guided stun guns is their small electrode spacing, typically not exceeding the diameter of the projectile, leading to poor stun-restraining effectiveness.

[0005] The patent application dated September 11, 2024, with application number CN202411270772.7, discloses a deployable electric shock projectile. It is the first to apply high-low pressure launch technology to 18.4mm and 12-gauge ammunition, stabilizing the projectile's internal ballistic performance. Upon impact, the high-voltage pulse released by the projectile immediately incapacitates the suspect without causing permanent injury. A safety block ensures power is cut off before the projectile leaves the barrel. After the safety is released, propellant gases drive a conductive push rod, activating the high-voltage electric shock module. The electric shock needle deploys simultaneously after the projectile leaves the barrel. A spatially misaligned anti-removal pin on the projectile body causes a secondary electric shock when the target touches the electrode. This invention's electric shock projectile has its own power supply and high-voltage module, eliminating the need for a tail wire; its structure is simple, ingenious, and low-cost. It is well known that the chamber length of a typical 18.4mm caliber firearm is approximately 70mm, and for proper feeding, the overall length of the ammunition is generally less than 70mm. Therefore, the existing type of deployable electric shock needle has the following drawbacks:

[0006] 1. Most of the space inside the projectile needs to be allocated to the power module and the electric shock component, with only a small portion of space left for the needle component. Therefore, the existing electric shock projectile uses a method of folding two unfolded electric shock needles into the head of the projectile. After unfolding, the distance between the two unfolded electric shock needles will not exceed 40mm.

[0007] 2. Since the needle-piercing component is located at the head of the projectile, it occupies a certain axial space. At the same time, the power module and the electric shock component need to be located inside the projectile, and the projectile also occupies a certain space in the radial direction, which affects the capacity of the power module, and thus affects the duration of electric shock and the effect of electric shock subduing.

[0008] 3. The projectile has a complex structure, is difficult to assemble, and has high manufacturing costs;

[0009] 4. The structure for disabling the power-on fuse is complex.

[0010] Therefore, reducing assembly difficulty, simplifying the electrical safety structure, increasing the spacing between the electric shock needles, and improving the battery capacity to enhance the duration and effectiveness of the electric shock are pressing problems that those skilled in the art need to solve. Thus, this application provides a novel deployable electrode radio blasting bullet that is simple in structure, rationally designed, highly safe, easy to assemble, has a large needle deployment spacing, a simple electrical safety release structure, and can improve the duration and effectiveness of the electric shock to solve the above problems. Summary of the Invention

[0011] The invention aims to solve the technical problems existing in the prior art. To this end, the invention provides a novel deployable electrode radio blasting bullet that is simple in structure, reasonable in design, highly safe, easy to assemble, has a large needle-spreading spacing, and a simple structure for releasing the electrical safety, thereby improving the duration of electric shock and the effectiveness of electric shock subjugation.

[0012] The technical solution adopted by the invention to solve its technical problem is:

[0013] A novel deployable electrode radio munition is provided, comprising a propellant charge, a projectile assembled within a cartridge case of the propellant charge, a sealing cap encapsulated at the mouth of the cartridge case, and a support block disposed between the sealing cap and the projectile; the projectile comprises a base, a shell-less electric munition module, an electric munition needle, a fixed needle, and flexible stabilizing fins, wherein: the shell-less electric munition module is a cylindrical module whose tail end is adapted to the inner cavity of the base and whose head end is equal to the outer diameter of the base, formed by encapsulating a power supply, a boost module, a control circuit board, and a control switch assembly with rigid potting compound, and whose tail end is inserted into the base. The internal structure is bonded with strong adhesive. The outer periphery of the head is evenly distributed with multiple longitudinal grooves that can accommodate the electric shock needles.

Their tails are fixedly installed to the bottom of the groove by pins and torsion springs. At least one electric shock needle is connected to the positive output of the boost module, and at least one electric shock needle is connected to the negative output of the boost module. The two ends of the three flexible stabilizing wings are fixedly connected to the electric shock needles and the longitudinal through grooves, respectively, and are folded laterally into the storage grooves on the base that are connected to the longitudinal through grooves.

[0014] In some optional embodiments, the bottom of the longitudinal through groove is set as a slope structure, which can limit the unfolding angle of the electric shock needle. By adjusting the slope angle of the bottom of the groove, the maximum unfolding angle of the electric shock needle can be 30°~60°.

[0015] In some optional embodiments, the head of the electro-acupuncture needle is provided with a curved portion, the head of the curved portion is provided with a needle tip with barbs, and the angle between the curved portion and the electro-acupuncture needle satisfies the following condition: after the electro-acupuncture needle is unfolded, the curved portion is parallel to the fixed needle.

[0016] In some optional embodiments, the electric shock needles are provided with four needles, which are evenly distributed in the longitudinal through groove on the outer periphery of the base. One electric shock needle is connected to the positive output terminal of the boost module, and one electric shock needle is connected to the negative output terminal of the boost module. The two electric shock needles connected to the positive and negative output terminals of the boost module are arranged diagonally. The two ends of the four flexible stabilizing wings are fixedly connected to the electric shock needles and the longitudinal through groove, respectively, and are laterally folded into the storage groove on the base that is connected to the longitudinal through groove.

[0017] In some alternative embodiments, the support block is an annular structure composed of 2 to 4 arc-shaped blocks, used for positioning the sealing cap for installation, and also for ejecting the sealing cap from the cartridge case by the projectile after the ammunition is fired.

[0018] In some optional embodiments, the propellant charge includes a cartridge, a primer mounted at the bottom of the cartridge, a primer disposed at the bottom of the primer, a propellant and a securing ring disposed within the primer, and a copper sheet disposed between the primer and the cartridge for sealing the ignition hole on the cartridge.

[0019] In some optional embodiments, the needle seat at the fixed needle tail is fixed to the needle insertion hole in the head of the shellless electric shock module by a shear pin; the control switch assembly consists of a MEMS switch, a normally open normally open switch, and a ready-to-fire switch. The MEMS switch, boost module, ready-to-fire switch, and power supply are connected in series to form a circuit. The ready-to-fire switch and the normally open normally open switch are connected in parallel. The MEMS switch is integrated on the control circuit board. The ready-to-fire switch is located in the needle insertion hole at the center of the head of the shellless electric shock module and is electrically connected to the control circuit board, and is triggered when the fixed needle hits the target.

[0020] In some optional embodiments, the needle seat at the fixed needle tail is bonded to the needle embedding hole of the head of the shellless electric shock module by strong adhesive; the control switch assembly is a normally closed micro switch, the normally closed micro switch, the boost module, and the power supply are connected in series to form a circuit, the normally closed micro switch is electrically connected to the control circuit board, and its operation button is exposed and faces one of the longitudinal through slots on the outer periphery of the base, and is pressed by the electric shock needle.

[0021] In some optional embodiments, the needle seat at the fixed needle tail is fixed to the needle insertion hole in the head of the shellless electric shock module by a shear pin; the control switch assembly consists of a MEMS switch, a normally closed micro switch, a normally open normally closed switch, and a ready-to-fire switch. The MEMS switch, boost module, ready-to-fire switch, normally closed micro switch, and power supply are connected in series to form a circuit. The normally open normally closed switch, micro switch, and ready-to-fire switch form a parallel circuit. The MEMS switch is integrated on the control circuit board. The normally closed micro switch and normally open normally closed switch are both electrically connected to the control circuit board. The operating button of the normally closed micro switch is exposed and faces one of the longitudinal through slots on the outer periphery of the base, and is pressed by the electric shock needle. The ready-to-fire switch is located in the needle insertion hole in the center of the head of the shellless electric shock module and is triggered when struck by the fixed needle.

[0022] In some alternative implementations, the stun round is the same size as an 18.4 mm shotgun shell, adapted for 18.4 mm shotguns.

[0023] Compared with existing technologies, the beneficial effects of the invention are:

[0024] 1. This invention distributes electric shock needles evenly on the outer periphery of the projectile base, converging them within the axial direction of the projectile. This does not occupy the radial space of the projectile, which is beneficial for increasing the installation space of the electric shock module and allowing the selection of a larger capacity power supply, thereby effectively improving the duration of electric shock and the electric shock subduing effect of the ammunition. In addition, with this electric shock needle arrangement structure, the longer the projectile, the larger the deployment spacing. The maximum deployment angle of the electric shock needles in this invention is 30°~60°, and the deployment spacing can reach 51~75mm, which increases the discharge spacing and can effectively improve the electric shock subduing effect.

[0025] 2. In this invention, the power supply, boost module, control circuit board, and control switch assembly are pre-encapsulated with hard potting compound to form a shell-less electric shock module. After assembly with the base, this module constitutes the main body of the projectile. The structure is simple and the assembly difficulty is low. At the same time, since the shell-less electric shock module eliminates the shell structure, it can increase the radial space of the electric shock module, which is conducive to increasing the power supply capacity and improving the duration of electric shock and the subduing effect of the ammunition.

[0026] 3. Using 3-4 electric shock needles in conjunction with a fixing needle can ensure good adhesion to the target and increase its stability;

[0027] 4. The design of the control switch assembly is simple and novel, and it can automatically unlock and connect power after the ammunition leaves the muzzle, ensuring the safety of the operator. Attached Figure Description

[0047] Example 1

[0048] As attached Figure 1 and attached Figure 3 As shown, this embodiment provides a novel deployable electrode radio strike projectile, including a propellant charge 1, a projectile 2 assembled inside a cartridge case of the propellant charge, a sealing cap 3 encapsulated at the mouth of the cartridge case, and a support block 4 disposed between the sealing cap and the projectile, wherein:

[0049] As attached Figure 3 As shown, the propellant charge 1 includes a cartridge case 1.1, a primer seat 1.2 installed at the bottom of the cartridge case, a primer 1.3 located at the bottom of the primer seat, propellant 1.4 and a propellant retaining ring 1.5 located within the primer seat, and a copper sheet 1.6 located between the primer seat and the cartridge case to seal the ignition hole on the cartridge case. The propellant charge is used to launch a projectile out of the muzzle of a firearm with a certain initial velocity. The firing principle is as follows: when the firing pin of the firearm strikes the primer of the electric shock cartridge, the primer ignites the propellant, causing it to pre-burn in the high-pressure chamber. After reaching a certain pressure, the high-temperature and high-pressure gas breaks through the copper sheet and enters the low-pressure chamber to propel the projectile.

[0050] As attached Figure 2 and attached Figure 3 As shown, the support block 4 is an annular structure composed of 2 to 4 arc-shaped blocks 4.1, used for positioning the sealing cover 3 for installation, and also for the sealing cover to be pushed out of the cartridge case by the projectile after the ammunition is fired. In this embodiment, the support block 3 is preferably composed of 3 arc-shaped blocks 4.1, which facilitates the separation of the support block after the projectile leaves the barrel, ensuring the normal deployment of the electrode needle.

[0051] The projectile 2 includes a base 2.1, a shell-less electric shock module 2.2, an electric shock needle 2.3, a fixed needle 2.4, and a flexible stabilizing wing 2.5, wherein:

[0052] As attached Figure 2 Appendix Figure 3 and attached Figure 5As shown, the casing-less electric shock module 2.2 is a cylindrical module whose tail is adapted to the inner cavity of the base 2.1 and whose head is equal to the outer diameter of the base 2.1, formed by encapsulating a power supply 2.2A, a boost module 2.2B, a control circuit board 2.2C, and a control switch assembly with rigid potting compound. Its tail is inserted into the base 2.1 and bonded with strong adhesive. The outer circumference of the head is evenly distributed with multiple longitudinal grooves 2.2.1 for accommodating the electric shock needles 2.3. The fixing needle 2.4 is embedded in the center of the head. The structural composition of the casing-less electric shock module 2.2 is shown in the attached figure. Figure 8 As shown, the power supply 2.2A, the boost module 2.2B, and the control switch assembly are all electrically connected to the control circuit board 2.2C. This invention pre-encapsulates the power supply, boost module, control circuit board, and control switch assembly into a shell-less electric shock module using rigid potting compound. This module, when assembled with the base, forms the main body of the projectile. The structure is simple and assembly is easy. Furthermore, by eliminating the shell structure, this shell-less electric shock module increases the radial space of the module, which is beneficial for increasing the power supply capacity and improving the duration and effectiveness of the electric shock.

[0053] As attached Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6 As shown, three electric shock needles 2.3 are evenly distributed within the longitudinal through groove 2.1.1 on the outer periphery of the base 2.1. Their tails are fixed to the bottom of the groove by pins and torsion springs. At least one electric shock needle 2.3 is connected to the positive output terminal of the boost module 2.2B, and at least one electric shock needle 2.3 is connected to the negative output terminal of the boost module 2.2B. This invention evenly distributes the electric shock needles on the outer periphery of the projectile base, converging them within the axial direction of the projectile. This does not occupy the radial space of the projectile, which is beneficial for increasing the installation space of the electric shock module, allowing for the selection of a larger capacity power supply, thereby effectively improving the duration of electric shock and the subduing effect of the ammunition. Furthermore, with this electric shock needle arrangement structure, the longer the projectile, the larger the deployment distance.

[0054] Preferably, the head of the electroacupuncture needle 2.3 is provided with a curved portion 2.3.1, the head of the curved portion 2.3.1 is provided with a needle tip with barbs, and the angle between the curved portion and the electroacupuncture needle satisfies the following condition: after the electroacupuncture needle 2.3 is unfolded, the curved portion 2.3.1 is parallel to the fixed needle 2.4, as shown in the attached figure. Figure 7 As shown.

[0055] Preferably, in this embodiment, the bottom of the longitudinal through groove 2.1.1 is designed with a sloped structure, which limits the deployment angle of the electric shock needle 2.3. The maximum deployment angle of the electric shock needle can be adjusted by adjusting the slope angle of the groove bottom. In this embodiment, the maximum deployment angle of the electric shock needle 2.3 is 30°~60°. The size of the electric shock bullet in this embodiment is the same as that of an 18.4mm shotgun shell, which is compatible with 18.4mm shotguns. To ensure smooth feeding of the firearm, the bullet length does not exceed 70mm. In this embodiment, the deployment distance of the electric shock needle can reach 51~75mm, which increases the discharge distance and effectively improves the electric shock subjugation effect.

[0056] As attached Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 7 As shown, the two ends of the three flexible stabilizing wings 2.5 are fixedly connected to the electric shock needle 2.3 and the longitudinal through groove 2.1.1, respectively, and are folded laterally into the storage groove 2.1.2 on the base 2.1 that is connected to the longitudinal through groove. When the electric shock needle is deployed, the flexible stabilizing wings can be pulled open to stabilize the flight attitude of the projectile.

[0057] Preferred options are listed below. Figure 3 Appendix Figure 5 Appendix Figure 7 and attached Figure 9 As shown, in this embodiment, the needle seat at the tail of the fixed needle 2.4 is bonded to the needle embedding hole at the head of the shellless electric shock module 2.2 by strong adhesive; the control switch assembly is a normally closed micro switch 2.2D, the normally closed micro switch 2.2D, the boost module 2.2B, and the power supply 2.2A are connected in series to form a circuit, the normally closed micro switch 2.2D is electrically connected to the control circuit board 2.2C, and its operation button is exposed and faces one of the longitudinal through slots 2.1.1 on the outer periphery of the base, and is pressed by the electric shock needle 2.3.

[0058] Working Principle: When the firing pin strikes the primer of the stun cartridge, the primer ignites the propellant, causing it to pre-burn in the high-pressure chamber. Once a certain pressure is reached, the high-temperature, high-pressure gas breaks through the copper plate and enters the low-pressure chamber, propelling the projectile, its head support block, and sealing cap at an accelerated pace within the chamber. After exiting the muzzle, the sealing cap and support block at the front of the projectile detach due to the loss of radial constraint from the chamber. Simultaneously, the stun needles on the side of the projectile, under the action of a torsion spring, deploy the connected flexible stabilizing fins, stabilizing the projectile's flight attitude. After the stun needles deploy, the normally closed microswitch, which was initially open due to pressure, returns to its closed state, connecting the circuit and allowing the stun cartridge to continuously output pulsed current. When the stun cartridge hits a target, the fixed needles at the front of the projectile and the stun needles on the side penetrate the target's clothing or skin, continuously applying pulsed current to the target, causing uncontrollable and violent muscle contractions or spasms, thereby incapacitating the target and achieving the purpose of electric shock subjugation.

[0059] Example 2

[0060] The only difference from Embodiment 1 is the automatic unlocking and power-on method, as shown in the attached document. Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 and attached Figure 10 As shown, in this embodiment, the needle seat at the tail of the fixed needle 2.4 is fixed to the needle embedding hole in the head of the shellless electric shock module 2.2 by a shear pin 5; the control switch assembly consists of a MEMS switch 2.2E, a normally open normally open switch 2.2F, and a ready-to-fire switch 2.2G. The MEMS switch 2.2E, the boost module 2.2B, the ready-to-fire switch 2.2G, and the power supply 2.2A are connected in series to form a circuit. The ready-to-fire switch 2.2G and the normally open normally open switch 2.2F are connected in parallel. The MEMS switch 2.2E is integrated on the control circuit board 2.2C. The ready-to-fire switch 2.2G is located in the needle embedding hole at the center of the head of the shellless electric shock module 2.2 and is electrically connected to the control circuit board 2.2C, and is triggered when the fixed needle hits the target.

[0061] Automatic unlocking and power-on principle: When the stun gun hits the target, the fixed needle at the front of the projectile and the stun needle on the side pierce the target's clothing or skin. After the fixed needle impacts, the shear pin breaks, triggering the standby switch. The MEMS switch is powered on, and the current forms a path through the boost module, the MEMS switch, and the standby switch. At the same time, because the MEMS switch is working, the normally open normally closed switch is closed, and the circuit is always in a conducting state, unaffected by the state of the standby switch. This allows the boost module to work continuously, applying pulsed current to the target, causing its muscles to contract violently or twitch uncontrollably, thereby rendering the target incapacitated and achieving the purpose of electric shock subjugation.

[0062] This embodiment enables the stun missile to remain energized during flight, only becoming energized after hitting the target, thus maximizing the application of limited electrical energy to the target.

[0063] Example 3

[0064] This embodiment combines the automatic unlocking and power-on methods of Embodiment 1 and Embodiment 2 to form a new automatic unlocking and power-on method. (See attached...) Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 and attached Figure 10As shown, the needle seat at the tail of the fixed needle 2.4 is fixed to the needle insertion hole at the head of the housingless electric shock module 2.2 by a shear pin 5; the control switch assembly consists of a MEMS switch 2.2E, a normally closed micro switch 2.2D, a normally open normally closed switch 2.2F, and a standby switch 2.2G. The MEMS switch 2.2E, the boost module 2.2B, the standby switch 2.2G, the normally closed micro switch 2.2D, and the power supply 2.2A are connected in series to form a circuit. The normally open normally closed switch 2.2F, the micro switch 2.2D, and the standby switch 2.2G are connected in series to form a circuit. Switch 2.2G forms a parallel circuit. The MEMS switch 2.2E is integrated on the control circuit board 2.2C. The normally closed micro switch 2.2D and the normally open normally closed switch 2.2F are both electrically connected to the control circuit board 2.2C. The operating button of the normally closed micro switch 2.2D is exposed and faces one of the longitudinal through slots 2.1.1 on the outer periphery of the base 2.1. It is pressed by the electric shock needle 2.3. The switch 2.2G is located in the needle embedding hole at the center of the head of the shellless electric shock module 2.2. It is triggered by being hit by the fixed needle 2.4.

[0065] Automatic unlocking and energizing principle: After the stun bullet is ejected from the muzzle, the side electrode needles unfold, and the normally closed micro switch, which was in an open state due to the pressure, returns to the closed state. When the stun bullet hits the target, the fixed needle at the front of the bullet and the stun needle on the side pierce the target's clothing or skin. After the fixed needle impacts, the shear pin breaks, triggering the standby switch. The MEMS switch is energized, and the current flows through the boost module. The MEMS switch, the standby switch, and the normally closed micro switch form a circuit. At the same time, because the MEMS switch is working, the normally open normally closed switch is closed, and the circuit is always in a conducting state, unaffected by the state of the standby switch. This allows the boost module to work continuously, applying pulse current to the target, causing its muscles to contract violently or twitch uncontrollably, thereby rendering the target incapacitated and achieving the purpose of electric shock subjugation.

[0066] This embodiment is designed with two automatic unlocking mechanisms, ensuring that the stun blast remains energized during flight and only unlocks after hitting the target, thus maximizing the application of limited electrical energy to the target.

[0067] Example 4

[0068] Unlike Embodiment 1, Embodiment 2, or Embodiment 3, the electric shock projectile in this embodiment is designed with four electrode needles 2.3. The four electric shock needles 2.3 are evenly distributed in the longitudinal through groove 2.1.1 on the outer periphery of the base 2.1. One electric shock needle 2.3 is connected to the positive output terminal of the boost module 2.2B, and one electric shock needle 2.3 is connected to the negative output terminal of the boost module 2.2B. The two electric shock needles 2.3 connected to the positive and negative output terminals of the boost module are arranged diagonally. The two ends of the four flexible stabilizing wings 2.5 are fixedly connected to the electric shock needles 2.3 and the longitudinal through groove 2.1.1, respectively, and are folded laterally in the storage groove 2.1.2 on the base 2.1 that is connected to the longitudinal through groove 2.1.1.

[0069] The electric shock bullet designed in this embodiment can further increase the spacing of the electric shock needles and improve the electric shock subjugation effect.

[0070] The above description is merely an embodiment of the invention and does not limit the patent scope of the invention. Any equivalent structural or procedural changes made using the content of the invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the invention.
