Description

Technical Field

[0001] This invention relates to the field of military automation technology, and in particular to a cartridge case structure with a safe firing device and its method of use. Background Technology

[0002] Traditional ammunition cartridge cases typically employ a mechanical impact-fired primer system. This involves a firing pin striking a preheater cap at the base of the cartridge case, causing the sensitive explosive inside to explode or ignite, which in turn ignites the propellant within the cartridge case, propelling the projectile. While this type of mechanical firing mechanism is technologically mature and highly reliable, it suffers from several inherent drawbacks: First, the firing mechanism requires precise control over the impact force and position of the firing pin and the sensitivity of the preheater cap, making it prone to misfires or delayed ignition. Second, the cartridge case is essentially scrapped after firing, especially the base firing assembly, resulting in significant waste of metal resources and environmental pollution. Third, mechanical firing mechanisms struggle to achieve precise timing control, failing to meet the demands of new combat scenarios such as sequential firing of multiple projectiles and coordinated operations. In recent years, some electrically fired cartridge case structures have emerged, using external power lines or contact points for ignition. However, existing electric firing schemes still have many shortcomings: on the one hand, most schemes require direct electrical contact between the cartridge case and the launching device, resulting in complex structures, low reliability, and difficulty in achieving independent multi-channel control; on the other hand, the electric firing assembly is usually fixed to the cartridge case as a whole, and is discarded as a whole after firing, resulting in high operating costs. In addition, in existing cartridge case structures, the ignition head and control system are inseparable, and single-use leads to waste of electronic circuitry, which is detrimental to environmental protection and economy.

[0003] Current replaceable ignition head cartridge case structures still suffer from the following technical problems: they are susceptible to electromagnetic interference during wireless power supply and signal transmission, leading to false triggering or failure to trigger; the ignition head replacement process is cumbersome and positioning is inaccurate; high-precision timing control cannot be achieved during multi-cartridge coordinated firing, and the status of each cartridge case is difficult to monitor in real time. Therefore, this invention provides a cartridge case structure and its method of use that combine safety, reusability, precise wireless control, and multi-cartridge coordinated firing capabilities. Summary of the Invention

An intelligent control board is fixedly installed, with an ignition head fixedly mounted at the top. The ignition head is detachable from the intelligent control board and is connected to gunpowder at its upper end. A control system module is installed at the lower end of the intelligent control board and the upper end of the power signal board. The control system module includes functional unit modules and an energy storage capacitor array. Each of the intelligent control board and the power signal board has one energy storage capacitor array and two functional unit modules. A power signal connection pipe is fixedly installed between the intelligent control board and the power signal board, connecting the intelligent control board to the various control system modules on the power signal board.

[0006] Furthermore, multiple cartridge case structures are arranged in a row at the same height. A transmitting coil is set at the lower end of the cartridge case structure. The transmitting coil and the receiving coil interact through electromagnetic induction to generate an electrical signal that triggers the cartridge case structure.

[0007] Furthermore, the energy storage capacitor array is fixedly installed below the intelligent control board and above the power signal board. The functional unit modules include an ignition power module, a main control MCU module, a signal response module, and an energy and signal receiving module. The ignition power module and the main control MCU module are fixedly installed at the lower end of the intelligent control board, and the signal response module and the energy and signal receiving module are fixedly installed at the upper end of the power signal board.

[0008] Furthermore, an ignition head housing is fixedly installed on the upper part of the intelligent control board, and an ignition head pin socket is fixedly installed inside the ignition head housing. The pins at the lower end of the ignition head pin socket are arranged on the upper part of the intelligent control board and connected to the various control system modules connected to the intelligent control board. An ignition head connection plate is fixedly installed on the ignition head pin socket. The ignition head connection plate is a detachable installation structure on the cartridge case mounting compartment, and the ignition head is fixedly installed on the ignition head connection plate.

[0009] Furthermore, a baffle nut is fixedly installed in the middle of the inner part of the cartridge case launcher. The cartridge case launcher and the baffle nut are fixedly connected by threads. A baffle plate is provided at the lower end of the baffle nut, which separates the projectile at the upper end from the gunpowder and ignition head at the lower end.

[0010] Furthermore, a cross-shaped notch is provided on the lower surface of the upper end of the barrier nut.

[0011] Furthermore, the lower end of the cartridge case launch tube is fixedly provided with a launch tube thread, and the inside of the cartridge case ignition tube is fixedly provided with an ignition tube internal thread. The cartridge case launch tube and the cartridge case ignition tube are fastened or loosened by the thread engagement between the launch tube thread and the ignition tube internal thread.

[0012] Furthermore, an electromagnetic shielding plate is fixedly installed between the receiving coil and the power signal board.

[0013] Furthermore, a method of using a cartridge case structure with a safe firing device includes the following steps: S1: Projectile and gunpowder status: Load the projectile from above the cartridge case launch tube, so that its lower end is embedded in the positioning groove on the lower surface of the upper end of the blocking nut; load an appropriate amount of gunpowder into the gunpowder magazine, so that the gunpowder connects to the projectile and wraps around the bottom of the projectile; S2: Wireless power supply and signal triggering: The transmitting coil is connected to the circuit.

[0014] The beneficial effects of this invention compared with the prior art are: (1) This invention fires the cartridge case through electromagnetic induction and sets up an electromagnetic shielding plate to effectively shield and isolate the wireless high-frequency electromagnetic field between the transmitting coil and the receiving coil, ensuring the stability of the control signal transmission and the reliability of the ignition action, preventing false triggering or failure to trigger, and significantly improving the safety of use; (2) The ignition head of this invention is detachably installed on the ignition head pin seat. The intelligent control board, power signal board, receiving coil, energy storage capacitor array and each functional unit module can be retained and reused. Compared with the traditional overall discarded cartridge case structure, this invention greatly reduces the cost of ammunition use and the waste of electronic resources, and has good economic and environmental benefits; (3) This invention realizes wireless power supply and signal transmission through electromagnetic induction between the receiving coil and the external transmitting coil.

Detailed Implementation

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example: Figures 1-10The illustration shows a cartridge case structure with a safe firing device and its usage method. The cartridge case includes a main cartridge case structure and an ignition control structure. The ignition control structure is located inside the lower part of the main cartridge case structure. The main cartridge case structure includes a cartridge case launch tube 1 and a cartridge case ignition tube 3. The launch tube 1 and the ignition tube 3 are fixedly connected and positioned above the ignition tube 3. The ignition control structure is fixedly located inside the lower part of the ignition tube 3. The ignition control structure includes a receiving coil 5. A power signal board 7 is fixedly mounted on the upper end of the receiving coil 5. An intelligent control board 4 is fixedly mounted on the upper end of the power signal board 7. An ignition head 9 is fixedly installed on the upper end of the board 4. The ignition head 9 is detachably installed on the intelligent control board 4. The upper end of the ignition head 9 is connected to gunpowder. A control system module is installed on the lower end of the intelligent control board 4 and the upper end of the power signal board 7. The control system module includes a functional unit module and an energy storage capacitor array 11. One energy storage capacitor array 11 and two functional unit modules are installed on the intelligent control board 4 and the power signal board 7 respectively. A power signal connection pipe 14 is fixedly installed between the intelligent control board 4 and the power signal board 7. The power signal connection pipe 14 connects the intelligent control board 4 and the control system modules on the power signal board 7. The main function of the cartridge case structure is to store gunpowder and launch the projectile. The igniter 9 ignites the gunpowder to launch the projectile. Before using the cartridge case structure, the projectile is placed on top of the cartridge case structure and inside the cartridge case launch tube 1. The receiving coil 5 at the lower end of the cartridge case ignition tube 3 generates an induced current due to the magnetic field. The induced current is connected to the power signal board 7 and then to the intelligent control board 4 through the power signal connector 14. The control system module on the intelligent control board 4 converts the electrical signal into heat energy. After the igniter 9 heats up, it ignites the gunpowder at the upper end of the igniter 9. The gunpowder connects to the projectile and launches it. The detachable installation of the igniter 9 on the intelligent control board 4 means that after the cartridge case structure is used once, only the igniter 9 itself needs to be replaced, without replacing the intelligent control board 4, receiving coil 5, power signal board 7, and other components at the lower end. The electromagnetic induction firing method allows the projectile to be launched wirelessly and can be reused. The receiving coil 5 receives the energy wirelessly transmitted by the transmitting coil, realizing wireless communication between the transmitting and receiving coils.

[0028] The cartridge case structure comprises multiple components arranged side-by-side at the same height. A firing coil is located at the lower end of each cartridge case. The firing coil and receiving coil 5 interact through electromagnetic induction to generate an electrical signal that triggers the cartridge case structure. This layout and cartridge case firing method allow for precise control of the firing time of multiple projectiles. Furthermore, only the projectiles and ignition head 9 need to be replaced, reducing costs and improving reloading efficiency.

[0029] The energy storage capacitor array 11 is fixedly installed below the intelligent control board 4 and above the power signal board 7. The functional unit module includes an ignition power module 12, a main control MCU module 13, a signal response module 15, and an energy and signal receiving module 16. The ignition power module 12 and the main control MCU module 13 are fixedly installed at the lower end of the intelligent control board 4, and the signal response module 15 and the energy and signal receiving module 16 are fixedly installed at the upper end of the power signal board 7. The energy storage capacitor array 11 is used to store electrical energy and provide power to the ignition power module 12 and the main control MCU module 13. The ignition power module 12 directly acts on the ignition head 9, and plays the role of energy signal conversion. The ignition power module 12 is an electronic power switch that controls the ignition head 9 to ignite, monitors the current and voltage, realizes ignition status analysis, and detects the ignition wire fuse status. The main control MCU module 13 is used for encoding and decoding communication signals and ignition logic control, and stores information and records ignition work. The signal response module 15 is used to modulate the response communication signal of the main control MCU module 13 onto the receiving coil 5 and send it. The energy and signal receiving module 16 is used to receive and rectify the energy received by the receiving coil 5, and to detect and demodulate the control signal of the transmitting coil before sending it to the main control MCU module 13.

[0030] An ignition head housing 19 is fixedly mounted on the upper end of the intelligent control board 4. An ignition head pin socket 18 is fixedly mounted inside the ignition head housing 19. The pins at the lower end of the ignition head pin socket 18 are arranged on the upper end of the intelligent control board 4 and connected to the various control system modules connected to the intelligent control board 4. An ignition head connection plate 8 is fixedly mounted on the ignition head pin socket 18. The ignition head connection plate 8 is a detachable mounting structure on the ignition head pin socket 18. The ignition head 9 is fixedly mounted on the ignition head connection plate 8. While supporting the ignition head 9 through the ignition head housing 19, the ignition head 9 is isolated from the intelligent control board 4 and the components at the lower end. The ignition head pin socket 18 facilitates the electrical signal connection between the ignition head 9 and the ignition power module 12. The detachable connection between the ignition head 9 and the ignition head connection plate 8 on the ignition head pin socket 18 directly reduces the structural cost and provides the possibility of multiple applications of the cartridge case firing structure.

[0031] A blocking nut 20 is fixedly installed in the middle of the interior of the cartridge case launcher 1. The interior of the cartridge case launcher 1 is divided into two areas by the blocking nut 20. The upper area is the cartridge case loading chamber 10, and the lower area is the gunpowder chamber 21. The cartridge case launcher 1 and the blocking nut 20 are fixedly connected by threads. A blocking plate is provided at the lower end of the blocking nut 20. The blocking plate separates the upper projectile from the lower gunpowder and ignition head 9.

[0032] The upper lower surface of the barrier nut 20 has a cross notch. The function of the cross notch is as follows: since the barrier nut 20 is installed inside the cartridge case 1, when it needs to be tightened, it is fixed inside the cartridge case 1 through the cross notch of the barrier nut 20; after the barrier nut 20 is tightened, the inside of the propellant magazine 21 is a closed cavity. After the igniter 9 ignites the propellant in the propellant magazine 11, high-temperature and high-pressure gas is generated in the sealed space of the propellant magazine 21. After the pressure reaches a certain value, the high-temperature and high-pressure gas breaks through the cross notch, and the high-pressure gas pushes the projectile into the air. The thickness of the cross notch determines the pressure inside the propellant magazine 11. The greater the thickness, the greater the pressure generated.

[0033] The lower end of the cartridge launch tube 1 is fixedly provided with a launch tube thread 2, and the inside of the cartridge ignition tube 3 is fixedly provided with an ignition tube internal thread 17. The cartridge launch tube 1 and the cartridge ignition tube 3 are fastened or loosened by the thread engagement between the launch tube thread 2 and the ignition tube internal thread 17.

[0034] An electromagnetic shielding plate 6 is fixedly installed between the receiving coil 5 and the power signal board 7. The electromagnetic shielding plate 6 is used to shield and isolate the high-frequency electromagnetic field between the transmitting coil and the receiving coil 5, so as to avoid affecting and interfering with the operation of the power signal board 7 and the various modules on the intelligent control board 4.

[0035] This invention provides a method for using a cartridge case structure with a safe firing device, comprising the following steps: S1: Projectile and gunpowder status: Load the projectile from above the cartridge case launch tube 1, so that its lower end is embedded in the positioning groove on the lower surface of the upper end of the blocking nut 20; load an appropriate amount of gunpowder into the gunpowder magazine 21, the gunpowder connects to the projectile and wraps around the bottom of the projectile; S2: Wireless power supply and signal triggering: The transmitting coil is connected to the circuit. After the transmitting coil is energized, it generates an alternating magnetic field. The receiving coil 5 is affected by the magnetic field and generates an induced current. The induced current is connected to the power signal board 7 and transmitted to the intelligent control board 4 through the power signal connection tube 14, and charges the energy storage capacitor array 11. S3: Safety Ignition Control: The external control system sends an ignition control signal to the receiving coil 5 through the transmitting coil; the energy and signal receiving module 16 detects and demodulates the control signal and transmits it to the main control MCU module 13; the main control MCU module 13 decodes the signal and performs ignition logic judgment. After confirming that the safety firing conditions are met, it controls the ignition power module 12 to be turned on, the energy storage capacitor array 11 releases electrical energy, the ignition head 9 heats up rapidly, ignites the upper gunpowder, and generates high-temperature and high-pressure gas in the sealed space of the gunpowder chamber 21. After the pressure reaches a certain value, the high-temperature and high-pressure gas will break through the cross notch of the barrier nut 20. The high-pressure gas pushes the projectile into the air and is launched from the cartridge launch tube 1. S4: Cartridge Case Recovery and Disassembly: After firing, recover the main structure of the cartridge case; rotate the cartridge case launch tube 1 and the cartridge case ignition tube 3, and separate the two through the launch tube thread 2 and the ignition tube internal thread 17; remove the burned ignition head 9 and the ignition head connecting plate 8; S5: Reloading: Replace the new ignition head 9 and ignition head connecting plate 8, reinstall them onto the ignition head pin seat 18, remove any remaining gunpowder residue from the cartridge case launch tube 1, and reload with new gunpowder and projectile; re-thread and tighten the cartridge case launch tube 1 and cartridge case ignition tube 3 to complete the reloading process, and the cartridge case can be used again.
