Description

Technical Field

[0001] This invention belongs to the field of firearms technology with electronic firing, and in particular, it is a firearms electronic firing device suitable for electronically fired ammunition. Background Technology

[0002] Electrically fired firearms are those that use electrical energy to directly fire ammunition within the chamber. The electrical energy is directly input into the primer of the ammunition, and a computer converts this energy into internal energy through a transducer within the primer, igniting the ammunition. Compared to traditional mechanical impact ignition and electromechanical impact ignition, electrically fired firearms eliminate the vibrations caused by impacts, thus improving shooting accuracy. Electrically fired firearms also reduce the number of moving parts within the firearm, simplifying its structure.

[0003] Existing electrically fired firearms have relatively complex structures and the conductive contact parts are mostly line contacts, which do not fully reflect the advantages of the electric firing principle, such as vibration-free firing and simplified firing structure. Summary of the Invention

[0004] The purpose of this invention is to provide an electric firing device for firearms suitable for electrically fired ammunition, so as to improve the reliability of electrically fired firearms, simplify the structure of electrically fired firearms, and facilitate the promotion and popularization of electrically fired firearms.

[0005] The technical solution to achieve the purpose of this invention is as follows:

[0006] An electric firing device for firearms suitable for electrically fired ammunition includes a firing pin, a lower receiver, an upper receiver, a bolt carrier, a bolt, ammunition, and a barrel, and further includes: an electric firing pin insulator, a conductive recoil spring, a conductive moving body, a recoil spring contact, and a conductive barrel clamp.

[0007] The firing pin, barrel, and recoil spring contact are conductors, and the lower receiver is an insulator, insulating and separating the conductive moving body, the conductive recoil spring, and the upper receiver.

[0008] The firing pin is externally equipped with an electric firing pin insulator to insulate and separate the firing pin from the bolt and bolt frame.

[0009] The barrel is fixed to the front end of the metal upper receiver, and the conductive barrel clamp is fixed to the barrel, connected to the conductive barrel, and connected to the rear wire.

[0010] The bolt carrier is fitted onto the bolt; the firing pin passes through the bolt and bolt carrier, and together with the electric firing pin insulator, the firing pin, the bolt carrier and the bolt mechanism, they form the automatic mechanism of the firearm.

[0011] The conductive moving body is disposed inside the lower housing, with its front end in contact with the tail of the firing pin; one end of the conductive recoil spring is sleeved on the rear end of the conductive moving body, and the other end is in contact with the recoil spring contact piece; the recoil spring contact piece is fixed inside the lower housing, and extends out of the lower housing to connect to the front lead wire.

[0012] The ammunition is provided with an electric firing ammunition shell and an electric firing ammunition primer contact at the bottom of the shell, which serve as the two poles required for electric firing; under the pre-pressure of the conductive recoil spring, the front end of the conductive moving body and the rear end of the firing pin, and the front end of the firing pin and the electric firing ammunition primer contact are coaxially pressed together.

[0013] After the bolt is locked, the bolt carrier moves forward a certain distance before the firing pin contacts the primer of the electrically fired ammunition. When the bolt is not locked or is not locked, the firing pin is located in the firing pin hole of the bolt and does not contact the primer of the electrically fired ammunition.

[0014] The significant advantages of this invention compared to existing technologies are:

[0015] The structure is simple, which improves reliability; the contact between the conductors is a surface contact, with low and stable contact resistance, no friction causing contact wear, and a high firing rate; the firing control is simple and reliable, with an incomplete firing safety, and single shot and burst fire are achieved by controlling the energization time of the firing power supply; this electric firing device is suitable for most firearms with a locking design, regardless of the firearm's automatic mode; this electric firing device can be used for a variety of firearms such as rifles, submachine guns, and machine guns.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-3 As shown, an electric firing device for firearms suitable for electrically fired ammunition according to the present invention includes an electric firing pin 6, an electric firing pin insulating housing 5, a plastic insulating lower receiver 13, a conductive recoil spring 2, a conductive moving body 3, a recoil spring contact 1, a conductive barrel 10, a conductive barrel clamp 11, a metal upper receiver 4, a bolt carrier 7, a bolt 8, an electrically fired ammunition 9, a front conductor 14, and a rear conductor 12.

[0024] One implementation involves an electrically fired firing pin 6 that is a multi-segmented metal cylinder 602. The insulating housing 5 of the firing pin has the same shape as the original firing pin, is made of plastic, and has a stepped hole 501 in the middle. The insulating housing 5 is fitted onto the firing pin 6 through the stepped hole 501 and is fitted into the bolt 8 and bolt carrier 7, insulating and separating the firing pin 6 from the bolt 8 and bolt carrier 7. The bolt carrier 7 is fitted onto the bolt 8 and is coaxially fitted with the bolt 8. The insulating housing 5, fitted onto the firing pin 6, passes through the bolt 8 and bolt carrier 7. The insulating housing 5, the firing pin 6, the bolt carrier 7, and the bolt 8 together constitute the automatic mechanism of the firearm, realizing functions such as feeding, locking, and extraction. A conductive barrel 10 is fixed to the front end of a metal upper receiver 4. The metal upper receiver 4 and a plastic-insulated lower receiver 13 form the outer shell of the firearm, housing the electric firing pin 6, the electric firing pin insulating shell 5, the conductive recoil spring 2, the recoil spring contact 1, the conductive moving body 3, the bolt carrier 7, the bolt 8, and the electric firing ammunition 9. The conductive moving body 3 is located inside the plastic-insulated lower receiver 13, with its front end 302 contacting the firing pin tail 601. One end 202 of the recoil spring 2 is fitted onto the rear end 301 of the conductive moving body 3, and the other end 201 contacts the recoil spring contact 1. The recoil spring 3, the electric firing pin insulating shell 5, the electric firing pin 6, the bolt carrier 7, and the bolt 8 are on the same axis. The conductive moving body 3 increases the contact between the recoil spring 2 and the electric firing pin 6. The conductive recoil spring 2 provides cushioning during recoil and power during return to its original position, and also acts as a conductor. The recoil spring contact 1 is fixed inside the plastic lower receiver 13, and extends out of the plastic lower receiver 13 to connect to the front guide wire 14. Since the length of the bolt carrier 7 is the same as the length of the internal cavity of the metal upper receiver 4, the recoil spring 2 and the conductive moving body 3 will not move out of the insulating plastic lower receiver 13. Under the preload of the conductive recoil spring 2, the firing pin 6, the conductive moving body 3, the conductive recoil spring 2, and the recoil spring contact 1 are pressed together and connected. The conductive barrel 10 can be the original barrel or a normal barrel. The conductive barrel clamp 11 is clamped onto the conductive barrel 10 and fixed to the conductive barrel 10 by screws, and is connected to the conductive barrel 10. There is no oxide layer on the barrel 1002 and the inner wall 1102 of the conductive barrel clamp at the contact point. When the electrically fired ammunition 9 is loaded into the chamber 1001 and the bolt 8 is fully locked, the electrically fired ammunition case 901 is pressed tightly against the inner wall of the chamber 1001, and the electrical circuits of the conductive barrel clamp 11, the conductive barrel 10, and the electrically fired ammunition case 901 are connected. Firing can be achieved by connecting the two ends of the firing power supply to the front lead 12 leading out of the conductive barrel clamp 11 and the rear lead 14 leading out of the recoil spring contact 1.

[0025] The conductive recoil spring 2 is made of metal and serves as a conductor for electric firing while providing recoil force to the automatic mechanism.

[0026] The conductive barrel 10 is made of metal and serves as a conductor for electric firing while bearing the pressure of the propellant gas chamber.

[0027] The insulating 5 of the firing pin housing can be a solid cylindrical housing or an insulating coating attached to the firing pin.

[0028] like Figure 6 As shown, the electric discharge circuit in the firearm is composed of the following components, starting from the conductive barrel clamp 11: conductive barrel clamp 11, conductive barrel 10, electrically fired ammunition 9, electrically fired firing pin 6, conductive moving body 3, conductive recoil spring 2, and recoil spring contact 1.

[0029] The electrically fired ammunition 9 is loaded into the chamber 1001. After the bolt 8 is locked, the front lead wire 12 from the conductive barrel clamp 11 and the rear lead wire 14 from the recoil spring contact 1 are connected to the two ends of the firing power source. Turning on the firing power source completely closes the circuit, and the electrically fired ammunition 9 is fired, thus achieving single-shot firing. If there is more than one round in the magazine, the firing power source remains energized. After one round is fired, the propellant gases in the conductive barrel 10 drive the automatic mechanism, and the bolt 8 completes the unlocking, extraction, feeding, and locking actions. After this round is fired, the electronic components inside the electrically fired ammunition 9 burn out, creating an internal open circuit and breaking the electrical firing circuit. When a new round is fed from the magazine into the chamber, the bolt 8 locks. After locking, when the automatic mechanism has completed its free travel, the electric firing pin 6 contacts the primer contact 902 of the electrically fired ammunition, reconnecting the circuit and firing a new round, achieving continuous firing. To stop continuous firing, simply disconnect the firing power supply.

[0030] During burst fire, firearms require an in-flight safety to ensure that the weapon only fires after it has fully locked out, thus preventing accidents. For example... Figure 5 As shown, the out-of-position safety of this invention is achieved through the free travel of the bolt carrier 7 after it is locked. Free travel is characteristic of firearms with a locking design; after the bolt is locked, the bolt carrier needs to move forward a certain distance before impacting the slide and reaching its forward position. In this invention, after the bolt is locked, the bolt carrier 7 moves forward a certain distance before the firing pin 6 contacts the primer contact 902 of the electrically fired ammunition. Only after contact is made can the electrical circuit be completed and firing occur. When the bolt is not locked or is not locked at all, the firing pin 6 is located inside the firing pin hole of the bolt 8 and does not contact the primer contact 902 of the electrically fired ammunition, thus no electrical circuit is formed, and firing is impossible. Therefore, the out-of-position safety function is achieved.

[0031] Good insulation of electrically fired firearms ensures reliable and safe firing. For example... Figure 1As shown, the excellent insulation of this electrically fired cartridge system is achieved through the firing pin insulating housing 5 and the plastic lower receiver 13. The firing pin insulating housing 5 insulates and separates the firing pin 6 from the bolt 8 and bolt carrier 7. The plastic lower receiver 13 insulates and separates the conductive moving part 3 and the conductive recoil spring 2 from the original metal upper receiver 4. The insulation measures of this electrically fired cartridge system ensure reliable firing even in relatively harsh environments.

[0032] Under the preload of the conductive recuperating spring, such as Figure 1 As shown, the primer contact 902 of the electrically fired ammunition, the front end 603 of the electrically fired firing pin, the rear end 601 of the electrically fired firing pin, and the front end 302 of the conductive moving body are coaxially pressed together. The preload of the conductive recoil spring 2 is about 30N, and the contact resistance between the three is very small. There is no translational friction between the contacts during the entire automatic mechanism's movement, and the contacts will not be worn by friction. This structure ensures a long service life for the electrically fired conductive components.

[0033] like Figure 4 As shown, the conductive firing pin can be a segmented structure, for example, divided into two sections, the front section 15 and the rear section 17, with a conductive spring 16 in the middle to reduce the impact of the conductive firing pin on the primer contact of the ammunition when the bolt is locked.

[0034] When a certain current is passed through the two wires led out from the device, the electrically fired bullet can be ignited. This invention simplifies the structure of the electrically fired bullet, greatly reduces the number of parts in the electrically fired barrel, and requires minimal modification to the original automatic mechanism structure of firearms. All conductive parts in the electrically fired circuit are in surface contact, reducing contact resistance and improving the reliability of the electrically fired bullet system. This invention solves the problem of low reliability in electrically fired firearms, and its ingenious design, simple structure, good impact resistance, and low and stable contact resistance between conductive parts make it suitable for various firearms.
