Description

Technical Field

[0001] This invention relates to the field of variable muzzle velocity launch technology, and in particular to a dual-chamber high-low pressure variable muzzle velocity launch control device. Background Technology

[0002] Existing launching devices typically achieve different initial velocities by adjusting the propellant charge, propellant type, or projectile mass. While this method can achieve initial velocity variation to some extent, it has several limitations: First, physical changes to the propellant charge require reconfiguration of the ammunition, which is complex, has a slow response time, and is not suitable for continuous firing or rapid switching missions. Second, differences in propellant charge can lead to uneven combustion pressure and propellant gas release rates, which can easily affect the stability and safety of the launching system. Third, traditional designs generally integrate the variable initial velocity function into the ammunition body, resulting in low versatility and standardization of the launching device, which is not conducive to the sharing of different weapon platforms.

[0003] Meanwhile, with the continuous development of electric ignition and electronic control technologies, using electronic control systems to achieve multi-stage energy release has become a new research direction. However, most existing multi-chamber ignition structures are only used to increase launch energy or reliability, lacking precise and controllable design for initial velocity. Their circuit switching logic is simple, making it impossible to achieve graded launch control while maintaining a compact structure and safety and stability. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to propose a dual-chamber high and low pressure variable initial velocity launch control device, so that the initial velocity adjustment no longer depends on the change of the charge amount, and to achieve different levels of ignition energy and launch initial velocity.

[0006] To achieve the above objectives, the present invention proposes a dual-chamber high-low pressure variable initial velocity firing control device, comprising: a bullet, an electric firing unit, a conductive unit, and an electric firing control unit; The bullet includes a projectile, a cartridge case, and two mutually isolated propellant chambers. The projectile and the propellant chambers are both located inside the cartridge case, and each of the propellant chambers is filled with propellant. The electric firing unit is integrated on the bullet and is used to independently ignite the propellant in each of the propellant chambers; The conductive unit includes multiple electric firing wires, each of which is connected to the electric firing unit; The electric firing control unit is electrically connected to the electric firing unit through the conductive unit. The electric firing control unit is configured to selectively connect one or more of the electric firing wires according to a preset initial velocity setting, thereby controlling one or more of the propellant chambers to be ignited and enabling the projectile to be fired at multiple initial velocities.

[0007] According to one embodiment of the present invention, the electric firing unit includes two ignition heads, an internal conductive wire, a conductive ring, and a conductive post; the conductive post and the conductive ring are coaxially arranged and embedded in the tail end of the bullet; the two ignition heads are respectively arranged adjacent to the two propellant chambers; one ignition head is connected to the conductive ring through an internal conductive wire, and the other ignition head is connected to the conductive post through another internal conductive wire.

[0008] According to one embodiment of the present invention, the conductive unit includes a first electrically triggered wire and a second electrically triggered wire, the first electrically triggered wire being electrically connected to the conductive post, and the second electrically triggered wire being electrically connected to the conductive ring.

[0009] According to one embodiment of the present invention, the conductive unit further includes a first electric firing pin, a second electric firing pin, and a connector; The connector is located at the rear of the bullet. A first electric firing pin and a second electric firing pin are mounted on the front end face of the connector. The first electric firing pin is electrically connected to the conductive post, and the second electric firing pin is electrically connected to the conductive ring. One end of the first electric firing wire is connected to the connector and electrically connected to the first electric firing pin, and one end of the second electric firing wire is connected to the connector and electrically connected to the second electric firing pin.

[0010] According to one embodiment of the present invention, it further includes a power supply unit; the electric firing control unit includes a trigger, a first gear controller, and a second gear controller; The input terminals of the first gear controller and the second gear controller are respectively electrically connected to the output terminal of the power supply unit; The output terminal of the first gear controller is connected to the first electric firing wire via the trigger, and the output terminal of the second gear controller is connected to the second electric firing wire via the trigger.

[0011] According to one embodiment of the present invention, both the first gear control controller and the second gear control controller are self-locking push-button switches, and are symmetrically arranged along the left and right sides of the trigger.

[0012] According to one embodiment of the present invention, two interlocking units are further included, which are symmetrically distributed on the left and right sides of the bolt carrier. The two interlocking units correspond to the first electric firing conductor and the second electric firing conductor, respectively. Each interlocking unit includes a conductive block and a conductive plate. The conductive block is disposed on the bolt carrier, and one end of the conductive block is electrically connected to the output terminal of the corresponding gear position controller. The conductive plate is disposed on the bolt carrier, and one end of the conductive plate is electrically connected to the corresponding electric firing conductor. When the bolt carrier returns to the in-frame position, the conductive block and the conductive plate come into contact with each other to form a current path, allowing the ignition signal to be transmitted to the electric firing conductor via the corresponding gear position controller and the interlocking unit.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The dual-chamber high and low voltage variable initial velocity launch control device of the present invention achieves selective connection of multiple electric firing leads by preset gear positions of the electric firing control unit. Different gear positions correspond to different combinations of electric firing leads and the participation mode of the propellant chamber, thereby achieving low / medium / high initial velocity output with simple electronic control means. It has a compact structure, intuitive operation, and quick switching.

[0014] 2. The dual-chamber high and low voltage variable initial velocity launch control device of the present invention achieves graded and controllable energy release through dual chambers and multi-line electronic control, so that the initial velocity adjustment no longer depends on the change of the charge amount, realizes different levels of ignition energy and launch initial velocity, improves the reliability and fault tolerance of the launch device, enhances the adaptability and versatility of continuous firing, and is suitable for a variety of mission scenarios.

[0015] 3. The dual-chamber high / low voltage variable muzzle velocity firing control device of the present invention uses an interlocking unit as an intermediate conductive component between the firing power supply and the electric firing wire. When the bolt recoils, the conductive block and the conductive plate separate, and the circuit is open. When the bolt returns to its original position, the conductive block and the conductive plate connect, the trigger is pulled, a circuit is formed, and the propellant is fired, effectively avoiding the problem of leakage and accidental discharge.

[0016] 4. The electric firing unit in the dual-chamber high and low pressure variable muzzle velocity firing control device of the present invention includes a conductive post and a conductive ring, which enables the bullet to maintain consistent ignition and accuracy at any angle of the central axis of the barrel, without the need for additional design of the bullet limiting structure, which is conducive to continuous firing and bullet universality.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The following is for reference. Figures 1 to 5 This describes a dual-chamber high-low pressure variable initial velocity launch control device according to an embodiment of the present invention.

[0026] Combination Figure 1 and Figure 2As shown, the dual-chamber high-low pressure variable initial velocity firing control device according to an embodiment of the present invention includes: a bullet 1, an electric firing unit 2, a conductive unit 3, and an electric firing control unit 6.

[0027] The bullet 1 includes a projectile 101, a cartridge case 102, and two isolated propellant chambers 103. The projectile 101 and propellant chambers 103 are both located within the cartridge case 102, and each propellant chamber 103 is filled with propellant. The propellant chambers 103 are arranged side-by-side. It should be noted that the amount of propellant in each propellant chamber 103 is selected according to actual needs. The amount of propellant in the two propellant chambers 103 is not equal. The shape of the projectile 101 is set according to actual needs. An electric firing unit 2 is integrated into the bullet 1 and is used to independently ignite the propellant in each propellant chamber 103. Specifically, the electric firing unit 2 is integrated at the rear end of the bullet 1, located behind the two propellant chambers 103, and is used to transmit current to the propellant to achieve electric firing.

[0028] The conductive unit 3 includes multiple electric firing wires, each of which is connected to the electric firing unit 2. The electric firing control unit 6 is electrically connected to the electric firing unit 2 through the conductive unit 3. The electric firing control unit 6 is configured to selectively connect one or more electric firing wires according to a preset initial velocity setting, thereby controlling one or more propellant chambers 103 to be ignited, enabling the projectile 101 to be launched at multiple initial velocities. The preset settings of the electric firing control unit 6 enable selective connection of multiple electric firing wires. For example, the preset settings are divided into three levels: high, medium, and low. In the high-level mode, two propellant chambers 103 are ignited simultaneously to achieve maximum energy release; in the medium-level mode, the propellant chamber 103 with a larger propellant charge is ignited alone; and in the low-level mode, the propellant chamber 103 with a smaller propellant charge is ignited alone.

[0029] According to an embodiment of the present invention, the dual-chamber high and low voltage variable initial velocity launch control device selectively connects multiple electric firing leads by preset gears in the electric firing control unit. Different gears correspond to different combinations of electric firing leads and propellant chamber participation modes, thereby achieving low / medium / high initial velocity output with simple electronic control means. It has a compact structure, intuitive operation, and quick switching.

[0030] like Figure 2As shown, the electric firing unit 2 includes two ignition heads 201, an internal conductive wire 202, a conductive ring 203, and a conductive post 204. The conductive post 204 and the conductive ring 203 are coaxially arranged and embedded in the tail end of the cartridge 1. Specifically, the tail end of the cartridge 1 is provided with a bottom sealing cap, and the conductive post 204 and the conductive ring 203 are mounted on the bottom sealing cap. Insulating material is filled between the conductive post 204 and the conductive ring 203. The two ignition heads 201 are respectively arranged adjacent to the two propellant chambers 103. One ignition head 201 is connected to the conductive ring 203 through an internal conductive wire 202, and similarly, the other ignition head 201 is connected to the conductive post 204 through another internal conductive wire 202.

[0031] The conductive unit 3 includes a first electric firing wire 301 and a second electric firing wire 302. The first electric firing wire 301 is electrically connected to the conductive post 204, and the second electric firing wire 302 is electrically connected to the conductive ring 203. Thus, the conductive ring 203 and the conductive post 204 can receive independent ignition signals from the electric firing control unit 6. Because the conductive ring 203 has a ring-shaped structure, the cartridge 1 can be stably conductive at any angle along the central axis of the barrel.

[0032] In some embodiments, such as Figure 3 As shown, the conductive unit 3 also includes a first electric firing pin 303, a second electric firing pin 304, and a connector 305.

[0033] A connector 305 is located at the rear of cartridge 1, and a first electric firing pin 303 and a second electric firing pin 304 are mounted on the front end face of the connector 305. The connector 305 is made of insulating material, rigidly fixing the first and second electric firing pins 303 and 304 in predetermined positions, maintaining spatial alignment accuracy with the conductive ring 203 and conductive post 204. Specifically, the first electric firing pin 303 is electrically connected to the conductive post 204, and the second electric firing pin 304 is electrically connected to the conductive ring 203. One end of the first electric firing lead 301 is connected to the connector 305 and electrically connected to the first electric firing pin 303, and one end of the second electric firing lead 302 is connected to the connector 305 and electrically connected to the second electric firing pin 304.

[0034] In some embodiments, such as Figure 5 As shown, the dual-chamber high / low voltage variable initial velocity launch control device also includes a power supply unit 7. The electric firing control unit 6 includes a trigger 601, a first-position controller 602, and a second-position controller 603. The power supply unit 7 can be powered by a battery or a rechargeable power source. The trigger 601 is a safety enable switch, a dual-channel switch, which only allows power to be supplied when pulled. The first-position controller 602 and the second-position controller 603 are position selection switches.

[0035] The input terminals of the first gear position controller 602 and the second gear position controller 603 are electrically connected to the output terminals of the power supply unit 7, respectively. The output terminal of the first gear position controller 602 is connected to the first electric firing wire 301 via a trigger 601, and the output terminal of the second gear position controller 603 is connected to the second electric firing wire 302 via a trigger 601. In other words, the input terminal of the trigger 601 is connected to the output terminals of the first gear position controller 602 and the second gear position controller 603, respectively, and the output terminal of the trigger 601 is connected to the first electric firing wire 301 and the second electric firing wire 302, respectively. The first gear position controller 602 and the second gear position controller 603 are configured to be selectively activated or simultaneously activated based on the initial speed gear selected by the user.

[0036] The trigger 601 is used to connect the current path between the electric trigger wire and the gear position controller when triggered. In one example, the first gear position controller 602 and the second gear position controller 603 are both self-locking push-button switches, symmetrically arranged on the left and right sides of the trigger 601 for easy operation.

[0037] In some embodiments, combined with Figure 1 and Figure 4 As shown, the dual-chamber high / low pressure variable muzzle velocity firing control device also includes two interlocking units 5, which are symmetrically distributed on the left and right sides of the bolt 4. The two interlocking units 5 correspond to the first electric firing conductor 301 and the second electric firing conductor 302, respectively. Each interlocking unit 5 includes a conductive block 501 and a conductive sheet 502. The conductive block 501 is mounted on the gun body, and one end of the conductive block 501 is electrically connected to the output terminal of the corresponding position controller. Figure 1 In the example shown, the interlock unit 5 on the left is connected to the output terminal of the second gear control 603, and the interlock unit 5 on the right is connected to the output terminal of the first gear control 602. A conductive plate 502 is mounted on the bolt 4, with one end electrically connected to the corresponding electric firing lead. When the bolt 4 returns to the in-flight position, the conductive block 501 and the conductive plate 502 come into contact, forming a current path, allowing the ignition signal to be transmitted to the electric firing lead via the corresponding gear control and interlock unit 5. When the bolt 4 has not returned to the in-flight position, the conductive block 501 separates from the conductive plate 502, cutting off the ignition circuit and preventing ignition.

[0038] The dual-chamber high / low pressure variable initial velocity firing control device according to the above embodiment can be installed in an explosion-proof gun or a variable-power firing weapon. The usage process is as follows: Before use, the operator can select the appropriate electric firing circuit according to the required muzzle velocity level. The selection is achieved through an independent level controller; the on / off state of different circuits determines the number of subsequent circuits allowed to participate in firing and the energy output level. In the ready state, bolt 4 is fully forward, and conductive block 501 and conductive plate 502 form electrical contact, establishing an ignition permission path; at this time, the weapon is ready to fire. Pulling trigger 601 completes the firing. When bolt 4 is not forward or recoiling, conductive block 501 and conductive plate 502 automatically disconnect, maintaining electrical isolation of the firing circuit, thereby preventing accidental energization and misfire.
