Description

Technical Field

[0001] This utility model relates to an electrically driven air gun firing system. Background Technology

[0002] Traditional air rifles rely on a manual lever to drive the hammer piston for chambering, which suffers from slow chambering speed, complex operation, and low continuous firing efficiency. Therefore, there is a need for further improvement in existing models. Summary of the Invention

[0003] The purpose of this invention is to provide an electrically driven air gun firing system that can ensure continuous firing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrically driven airgun firing system includes a fuselage, on which are mounted a power module, a transmission module, a firing execution module, a feeding module, and a decoy device. The power module includes a battery assembly, a motor, and a reducer. The firing execution module includes a hammer piston and a power spring. The feeding module includes an automatic feed wheel and a feed wheel lever. The decoy device includes a decoy locking tongue for engaging or disengaging the transmission module and the hammer piston. When the transmission module and the hammer piston are engaged, the motor drives the transmission module through the reducer to automatically chamber the hammer piston against the force of the power spring. After chambering, the decoy locking tongue disengages the transmission module from the hammer piston, and the transmission module returns to its original position, triggering the feed wheel lever to rotate the automatic feed wheel and feed ammunition.

[0006] The advantages of this invention are that it can ensure the continuity of firing, has a fast loading speed, is simple to operate, and has high efficiency in continuous firing. Attached Figure Description

[0010] As attached Figure 1 As shown, an electrically driven air gun firing system includes a fuselage, on which a power module, a transmission module, a firing execution module, a feeding module, and a release device are mounted.

[0011] The power module includes a battery pack 21, a motor 22, and a reducer 23.

[0012] The firing execution module includes a hammer piston 31 and a power spring 32; the ammunition feeding module includes an automatic feed wheel 41 and a feed wheel lever 42.

[0013] The disengagement device includes a disengagement latch 51 for linking or disengaging the transmission module and the hammer piston 31. When the transmission module and the hammer piston 31 are linked, the motor 22 drives the transmission module through the reducer 23 to drive the hammer piston 31 to automatically load the chamber against the action of the power spring 32. After loading, the disengagement latch 51 disengages the transmission module from the hammer piston 31, and the transmission module returns to trigger the spring wheel lever 42 to rotate the automatic spring wheel 41 to feed ammunition.

[0014] The receiver includes a gas pipe 11 and a barrel 12. The automatic magazine 41 is installed between the gas pipe 11 and the barrel 12. The hammer piston 31 is placed inside the barrel 12 and can move back and forth along the axial direction of the barrel 12. The rear end of the barrel 12 is blocked with a rear plug 13. The power spring 32 is placed inside the barrel 12, with one end connected to the rear plug 13 and the other end connected to the hammer piston 31.

[0015] The rear end of the barrel 12 is also provided with a striking mechanism, which includes a striking hook 61. The hammer piston 31 is provided with a hook groove 62 corresponding to the striking hook 61. When automatically loading, the hook of the striking hook 61 is engaged in the hook groove 62, and the power spring 32 is in a stored energy state. The striking mechanism is activated to make the striking hook 61 rotate, and the hook disengages from the hook groove 62, so that the hammer piston 31 fires the bullet in the automatic magazine 41 under the action of the power spring 32.

[0016] The transmission module includes a small bevel gear 71, a large bevel gear, a spur gear 73, and a rack 74. The small bevel gear 71 is mounted on the output shaft of the reducer 23. The large bevel gear and the spur gear 73 are coaxially arranged and mesh with the small bevel gear 71. The spur gear 73 has a meshing section 731 and a disengaging section 732. The meshing section 731 of the spur gear 73 can mesh with the rack 74. The rack 74 is fixedly connected to the hammer piston 31. A return spring 75 is also provided between the rack 74 and the machine body. A release latch 51 is fixedly provided on the machine body, and the end of the release latch 51 forms an inclined surface 52. The hammer piston 31 is connected to a telescopic rod 54 via a telescopic spring 53. During the meshing transmission of the spur gear 73 and the rack 74, the telescopic rod 54 extends under the action of the telescopic spring 53 and abuts against the rack 74 (abutting against the protrusion 741 in the rack 74), so that the hammer piston 31 can overcome the action of the power spring 32 and the return spring 75 until it is loaded into the chamber. Under the action of the inclined surface 52, the telescopic rod 54 retracts into the hammer piston 31. The rack 74 disengages from the spur gear 73 due to the disengagement section 732 of the spur gear 73, and the telescopic rod 54 disengages from the rack 74.

[0017] The battery assembly 21 is used to power the motor 22, which is connected to the reducer 23 to reduce speed and increase torque. The small bevel gear 71 at the output shaft of the reducer 23 drives the large bevel gear to change the direction of power transmission. Then, the large bevel gear and the coaxial spur gear 73 drive the rack 74 to achieve linear reciprocating motion of the rack 74.

[0018] The linear reciprocating motion of rack 74 pushes hammer piston 31, achieving the loading motion. When hammer piston 31 moves backward, it compresses power spring 32 and reaches the plate-hammer hook 61 of the plate-hammering mechanism, achieving engagement. After engagement, the engagement is completed by the release latch 51. After engagement, rack 74 can continue to move backward. At this time, since rack 74 no longer bears the heavy load of pushing power spring 32 (the stage where the gear disengages from the spur gear 73 in the disengagement section 732), it ensures that the gear teeth of rack 74 will not be damaged when disengaging from spur gear 73, ensuring the smooth operation of the work. The release latch 51 protects the notched spur gear 73 and rack 74, preventing tooth breakage during the heavy load disengagement and engagement process (preventing damage to spur gear 73 and rack 74).

[0019] Once the hammer piston 31 is reliably engaged with the trigger hook, the release latch 51 disengages the rack 74. At this point, the spur gear 73 and rack 74 are no longer under the pressure of the power spring 32. The spur gear 73 has also rotated to the disengagement section 732, disengaging from the rack 74. Under the action of the rack 74 return spring 75, the rack 74 quickly returns forward, clearing the path for the hammer piston 31 to move forward during firing. The user can then pull the trigger to fire.

[0020] When the rack 74 returns to its original position quickly, it collides with the cartridge wheel lever 42, causing the automatic cartridge wheel 41 to rotate. This aligns the bullet in the automatic cartridge wheel 41 with the ejection position of the barrel 12. Pulling the trigger causes the hammer piston 31 to move forward, pushing the air in the gas tube 11 and ejecting the bullet from the barrel 12, thus completing the firing. The automatic cartridge wheel 41 ensures the continuity of firing and can be a conventional automatic cartridge wheel structure.

[0021] As attached Figure 2 As shown, a countersunk hole 55 is provided on the outer peripheral wall of the hammer piston 31. The telescopic rod 54 is inserted into the countersunk hole 55. One end of the telescopic spring 53 is fixedly connected to the bottom of the countersunk hole 55, and the other end is connected to the telescopic rod 54. Under the action of the telescopic spring 53, the head of the telescopic rod 54 extends out of the countersunk hole 55. Under the action of the inclined surface 52, the telescopic rod 54 falls completely into the countersunk hole 55 and retracts into the hammer piston 31.

[0022] The transmission module can be in various forms, such as the attached Figure 3 As shown, the transmission module includes a connecting seat 81, a lead screw 82, and a nut seat 83. The lead screw 82 is connected to the output shaft of the reducer 23 through the connecting seat 81, and the nut seat 83 is connected to the lead screw 82 and fixedly connected to the hammer piston 31.

[0023] The battery assembly 21 powers the motor 22, which, through a reducer 23, reduces speed and increases torque. The reducer 23's output shaft connector 81 then drives the lead screw 82 to rotate, causing the lead screw 82 and its nut seat 83 to reciprocate linearly. This linear reciprocating motion of the lead screw 82 and nut seat 83 pushes the hammer piston 31, causing it to fire. When the hammer piston 31 moves backward, it compresses the power spring 32 and reaches the hammer hook 61 of the plate-firing mechanism, thus engaging the hammer. After engagement, the motor 22 reverses, ensuring the lead screw 82 and nut seat 83 move forward rapidly, guaranteeing that the hammer piston 31's forward firing motion is undisturbed.

[0024] When the lead screw 82 and nut seat 83 quickly return to their original positions, they collide with the cartridge wheel lever 42, causing the automatic cartridge wheel 41 to rotate. This aligns the bullet in the automatic cartridge wheel 41 with the bullet ejection position in the barrel 12. Pulling the trigger causes the hammer piston 31 to move forward, pushing the air in the gas tube 11 and causing the bullet to be ejected from the barrel 12, thus completing the firing. The automatic cartridge wheel 41 ensures the continuity of firing.

[0025] The electronic control unit 9 of the gun includes: a power indicator light, a start button (load indicator light), a main power / single shot / burst fire control button, a circuit control board, and a wiring assembly.

[0026] The main power / single shot / burst fire control key is in the main power position, with the power off. When the main power / single shot / burst fire control key is in the single shot position, pressing the start key activates motor 22, compressing the power spring 32 and causing the hammer piston 31 to move backward to the cocking position, loading the bolt. Simultaneously, the start key indicator light illuminates, indicating that the bolt is cocked and ready to fire. After firing, pressing the start key again cycles through cocking and firing.

[0027] With the main power / single / burst fire control key selected in the burst fire position, pressing the start key will activate motor 22, compressing the power spring 32 and causing the hammer piston 31 to move backward to the cocking position, thus loading the hammer. Simultaneously, the start key indicator light will illuminate, indicating that the hammer is cocked and ready to fire. After firing, there is no need to press the start key again; motor 22 will automatically restart to cock the hammer, and this automatic firing cycle will repeat after each firing.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
