Abstract
Description
Technical Field
[0001] This invention relates to the field of electric training equipment technology, and in particular to a gunshot simulation structure for an electric training firearm. Background Technology
[0002] In the field of electric training equipment technology, the impact sound after the hammer is released is generally very quiet, or does not have the effect of a real gun firing sound. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a gun sound simulation structure for an electric training firearm, which can effectively produce obvious real gun firing sounds, thereby providing people with a better real gun firing experience.
[0004] The objective of this invention is achieved as follows:
[0005] A gunshot simulation structure for an electric training firearm includes a launcher base, a sliding sleeve at the upper end of the launcher base, a grip fixedly connected to the lower end of the launcher base, a recoil spring component between the launcher base and the sleeve, a trigger and a trigger spring on the launcher base, a piston cylinder fixed inside the sleeve, a piston and a piston spring seat arranged sequentially from front to back inside the piston cylinder, the piston and piston cylinder slidingly engaging, the front end face of the inner hole of the piston cylinder being the impact surface of the piston, a sloping boss at the lower rear end of the piston, the piston having an axially rearward inner hole, a piston spring inside the inner hole of the piston, the rear end of the piston spring being axially positioned on the piston spring seat, and the lower end of the piston spring seat extending out of the sleeve and fixed to the launcher base;
[0006] The transmitter base is equipped with a cylindrical pin, a limit stop pin, and a trigger pull rod. The limit stop pin is located behind the cylindrical pin. A piston limit block and a piston limit spring are fitted on the cylindrical pin. The piston limit spring is a torsion spring. The two ends of the piston limit spring act on the upper end of the limit stop pin and the piston limit block, respectively. Behind the piston limit block, from top to bottom, there are a mounting arm, a limit arm, and a tenon. In normal condition, under the action of the piston limit spring, the limit arm abuts against the lower end of the limit stop pin, forming a circumferential limit on the piston limit block and limiting the upper limit position of the piston limit block mounting arm.
[0007] In the initial state, the front end face of the piston is in contact with the impact surface of the piston cylinder. When the sleeve moves backward, the piston cylinder drives the piston to move backward. The inclined boss on the piston presses backward against the hook arm of the piston limit block and passes over the hook arm of the piston limit block. The piston limit block is reset under the action of the piston limit spring. After the sleeve and piston move backward into place, the sleeve is released. Under the action of the return spring component, the sleeve automatically resets. The inclined boss of the piston will be hooked by the hook arm of the piston limit block to form a hook.
[0008] The upper end of the trigger extends into the transmitter base, and the upper end of the trigger is provided with a hanging shaft. The front end of the trigger pull rod is sleeved on the hanging shaft, and the trigger pull rod is provided with a hook, which is located behind the protrusion of the piston limit block.
[0009] When the trigger is pulled, the trigger lever moves forward under the action of the trigger, the hook catches the protrusion of the piston limit block, and drives the piston limit block to rotate, causing the piston limit block's latching arm to rotate downward and release the piston's inclined boss, thus releasing the latch. Then, under the action of the piston spring, the piston returns forward and strikes the piston cylinder's impact surface, producing an impact sound that simulates the firing sound of a bullet.
[0010] When the trigger is released, the trigger lever moves backward to reset, and the piston limit block resets under the action of the piston limit spring.
[0011] Preferably, a hammer is hinged to the rear end of the transmitter base, and a hammer limiting surface is provided at the tail end of the sleeve corresponding to the upper end of the hammer. When the sleeve moves backward, the hammer is pressed down by the sleeve, and the hammer latch is positioned at the rear of the trigger lever. When the trigger lever moves forward under the drive of the trigger, the hammer is released, and the hammer rotation stops at the limiting surface of the sleeve, simulating the hammer action of a real gun firing.
[0012] Preferably, the impact surface of the piston cylinder is provided with a strip-shaped through hole for ventilation, which can dissipate the impact sound outward.
[0013] Preferably, the piston is made of steel or plastic.
[0014] Preferably, a gearbox component is fixed at the lower end of the transmitter base, a gear is provided at the upper end of the gearbox component, and a rack that can slide longitudinally is provided on the lower side of the sleeve, with the gear meshing with the rack.
[0015] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:
[0016] This invention, through its novel design, can effectively simulate gunshots, thereby providing a better real gun shooting experience. Attached Figure Description

[0024] The working principle and structure of the present invention will be further described in detail below with reference to the embodiments and accompanying drawings.
[0025] In this invention, the direction of gun barrel firing is considered forward, and the opposite direction is considered backward.
[0026] As shown in the figure, a gun sound simulation structure for an electric training firearm includes a transmitter base 11, a sleeve 3 connected to the upper end of the transmitter base 11, a grip 12 connected to the lower end of the transmitter base 11, a circuit board component 17 fixed to the front end of the transmitter base 11, a recoil spring component 18 installed below the circuit board component 17, the front end of the recoil spring component 18 being placed in a circular hole at the lower part of the sleeve 3, the rear end of the recoil spring component 18 being placed in a circular hole at the lower part of the circuit board component 17, the rod part of the recoil spring component 18 being fixed, the rear end of the spring part being positioned, and the lower part of the front end of the sleeve 3 being able to compress the spring part.
[0027] The transmitter base 11 is equipped with a trigger 16 and a trigger spring 15. A piston cylinder 2 is fixed inside the sleeve 3. A piston 1 and a piston spring seat 5 are arranged sequentially from front to back inside the piston cylinder 2. The piston 1 and the piston cylinder 2 are in sliding fit. The front end face of the inner hole of the piston cylinder 2 is the impact surface 103 of the piston 1. A sloping boss 104 is provided at the lower part of the rear end of the piston 1. The piston 1 has an axially rearward inner hole. A piston spring 4 is provided in the inner hole of the piston 1. The rear end of the piston spring 4 is sleeved on the piston spring seat 5 for axial positioning. The lower end of the piston spring seat 5 extends out of the sleeve 3 and is fixed on the transmitter base 11.
[0028] The transmitter base 11 is provided with a cylindrical pin 6, a limiting pin 9, and a trigger lever 13. The limiting pin 9 is located behind the cylindrical pin 6. A piston limiting block 7 and a piston limiting spring 8 are fitted on the cylindrical pin 6. The piston limiting spring 8 is a torsion spring. The two ends of the piston limiting spring 8 act on the upper end of the limiting pin 9 and the piston limiting block 7, respectively. Behind the piston limiting block 7, from top to bottom, there are a mounting arm 108, a limiting arm 109, and a tenon 105. In normal condition, under the action of the piston limiting spring 8, the limiting arm 109 abuts against the lower end of the limiting pin 9, forming a circumferential limit on the piston limiting block 7, limiting the upper limit position of the mounting arm 108 on the piston limiting block 7.
[0029] In the initial state, the front end face of piston 1 is in close contact with the impact surface 103 of piston cylinder 2. When sleeve 3 moves backward, piston cylinder drives piston 1 to move backward. The inclined boss 104 on piston 1 will press backward against the hanging arm 108 of piston limit block 7 and pass over the hanging arm 108 of piston limit block 7. Then, piston limit block 7 resets under the action of piston limit spring 8. After piston 1 and sleeve 3 move backward to their positions, sleeve 3 is released. Under the action of return spring component 18, sleeve 3 can automatically reset, piston cylinder 2 resets synchronously, and the inclined boss 104 of piston 1 will be caught by the hanging arm 108 of piston limit block 7 to form a hanging mechanism.
[0030] The upper end of the trigger 16 extends into the transmitter base 11. The upper end of the trigger 16 is provided with a hanging shaft 101. The front end of the trigger lever 13 is sleeved on the hanging shaft 101. The middle part of the trigger lever 13 is provided with a hook 102, which is located behind the tenon 105 of the piston limit block 7.
[0031] When the trigger 16 is pulled, the trigger lever 13 moves forward under the action of the trigger 16. The hook 102 hooks the tenon 105 of the piston limit block 7 and drives the piston limit block 7 to rotate, causing the latch arm 108 of the piston limit block 7 to rotate downward and release the inclined boss 104 of the piston 1, thus releasing the latch. Then, under the action of the piston spring 4, the piston 1 returns to its original position and strikes the impact surface 103 of the piston cylinder 2, producing an impact sound that simulates the shooting sound produced by the firing of a bullet.
[0032] When the trigger 16 is released, the trigger lever 13 moves backward to reset, and the piston limit block 7 resets under the action of the piston limit spring 8.
[0033] The piston cylinder 2 has a strip-shaped through hole 106 on its impact surface for ventilation, which can effectively dissipate the impact sound outward. The piston 1 is made of steel or plastic.
[0034] A gearbox component 14 is fixed to the lower end of the transmitter base 11. A gear is provided on the upper end of the gearbox component 14. A longitudinally sliding rack is provided on the lower side of the sleeve 3. The gear drives the sleeve 3 to move backward and complete the mounting process. That is, the gearbox component 14 drives the mounting process and automatically resets the transmitter via the return spring component.
[0035] The rear end of the transmitter base 11 is hinged with a hammer 107. The tail end of the sleeve 3 is provided with a hammer limiting surface corresponding to the upper end of the hammer 107. When the sleeve 3 moves backward, the hammer 107 is pressed down by the sleeve 3 to achieve hammer lock-up. The rear part 201 (jaw) of the trigger lever 13 is connected to the lower part (hook) of the hammer 107. When the trigger lever 13 moves forward under the drive of the trigger 16, the hammer 107 is released. The hammer 107 rotates and stops at the hammer limiting surface of the sleeve 3, retaining the mechanism action of the live-fire hammer 107. The hammer lock-up principle can be the same as the existing technology.
[0036] In this embodiment, the lower part of the hammer 1 is provided with a hook, and the trigger pull rod 13 is provided with a locking slot. When the hammer 1 is pressed down by the sleeve 3, the hook of the hammer 1 presses against the locking slot on the trigger pull rod 13, causing the trigger spring to deform and the trigger pull rod 13 to move forward a certain distance. Afterward, the trigger spring returns to its original position, and the hook of the hammer 1 engages with the locking slot of the trigger pull rod 13. When the trigger pull rod 13 moves forward under the action of the trigger 16, the engagement is released. See [reference needed]. Figure 2 The rear part 201 of the trigger lever 13 is in the hooked state. The hook of the hammer 1 is L-shaped and can hook onto the lower end of the latch on the trigger lever 13 without affecting the forward movement of the trigger lever 13. When the hook presses against the latch, the arc surface on the outer side of the hook pushes the trigger lever 13 forward.
[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
