Description

Technical Field

[0001] This invention relates to the field of simulated gun technology, and in particular to a simulated gun two-stage firing mechanism and its working method. Background Technology

[0002] The semi-physical simulation equipment used in the special operations simulation training system is a simulated firearm that trainees can operate, which can enhance the user's experience. Among them, the recoil generation and the feel of trigger and safety position changes are important parts of enhancing the simulation experience. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simulated two-stage firing mechanism for a simulated gun and its working method, which can greatly improve the simulation experience of the user when pulling the trigger.

[0004] The objective of this invention is achieved as follows:

[0005] A simulated two-stage firing mechanism for a firearm includes a trigger, a trigger rod holder, and a trigger linkage. The trigger rod holder is mounted horizontally in front of the trigger.

[0006] The trigger's actuating end is fixedly equipped with a forward-extending hinged arm. The front end of the hinged arm is hinged to the rear end of the trigger linkage. The front end of the trigger linkage overlaps the rear end of the trigger rod seat. A T-slot is longitudinally provided within the trigger rod seat, housing a firing release spring and a trigger rod. A firing release spring pin is transversely provided on the trigger rod seat, limiting the front end of the firing release spring. The trigger rod is located behind the firing release spring, and its cross-section is T-shaped. The trigger rod slides within the T-slot, allowing for firing release. The two ends of the spring are connected to the release spring pin and the trigger rod, respectively. The trigger rod has a trigger rod pin that extends upward and passes through a T-slot. The trigger rod pin is located in front of the trigger linkage. Under normal conditions, there is a gap between the trigger linkage and the trigger rod pin. The upper rear end of the trigger rod seat has a clearance notch. The clearance notch is used to make way for the hinge end of the trigger articulation arm and the trigger linkage. The front end of the clearance notch forms a fulcrum that causes the front end of the trigger rod seat to tilt upward. The upward tilting process of the front end of the trigger rod seat can be achieved through the trigger rod pin.

[0007] Preferably, the front end of the trigger hinge arm is hinged to the rear end of the trigger link via a trigger link pin. A release torsion spring is fitted on the trigger link pin. The two ends of the release torsion spring act on the trigger hinge arm and the trigger link respectively. Under the action of the release torsion spring, the front end of the trigger link rests downward on the rear end of the trigger top rod seat.

[0008] Preferably, the two ends of the release spring are welded or sleeved to the release spring pin and the trigger rod, respectively.

[0009] Preferably, a trigger pin is inserted into the trigger rod to fix the trigger rod.

[0010] A working method for a simulated two-stage firing mechanism of a simulated gun.

[0011] When the trigger is pulled, the trigger is resisted by the trigger spring, and the trigger pushes the trigger linkage forward through the hinge arm until the trigger linkage contacts the trigger push pin;

[0012] Continue pulling the trigger, and the trigger linkage pushes the trigger push rod forward through the trigger push rod pin, compressing the firing release spring. At this time, the trigger is subjected to the resistance of the trigger spring and the resistance of the firing release spring, realizing the step-by-step increase of the trigger force, simulating the interaction feel between the trigger and the bolt.

[0013] Continue pulling the trigger, using the front end of the notch as a fulcrum. The trigger hinge arm moves the rear end of the trigger linkage downward, and the front end of the trigger push rod seat tilts upward until the front end of the trigger push rod seat passes the trigger push rod pin. At this point, the trigger push rod seat disengages from the trigger push rod pin, and the trigger push rod returns to its original position under the action of the release spring. The trigger force jump decreases, simulating the feel of the sear releasing the hammer.

[0014] Due to the adoption of the above technical solution, this invention offers reliable reciprocating motion, realistic tactile feedback, and its design concept can be implemented in most trigger-rotating simulated firearms, demonstrating strong portability and wide applicability. This invention has the following characteristics:

[0015] Beneficial effects:

[0016] (1) A simulated two-stage firing mechanism for a simulated gun requires less space, mainly in the longitudinal space, and is especially suitable for small firearms. Compared with actual firearms, it only needs to add a small set of mechanisms in front of the trigger to achieve a step-by-step and smooth increase in trigger force. For example, the 95-1 series only requires an installation space of about 10×10×40. This innovative feature can effectively reduce the difficulty of achieving the simulated two-stage firing feel of firearms and save more space for other internal structures of the firearm.

[0017] (2) A simulated two-stage firing mechanism for a firearm provides a realistic two-stage firing feel. Through structural control, the user experiences a better simulation when pulling the trigger. When the finger contacts the trigger and slowly pulls it back, the trigger initially transmits a stable rotational torque. Upon reaching the initial point of interaction between the trigger and the mechanism, the trigger force increases dramatically in a step-like manner. At this point, the user can simulate the interaction between the trigger and the internal "bolt" of the firearm. Continuing to pull the trigger, the trigger force increases steadily and continuously until it reaches its release limit, at which point the trigger is released, and the trigger force returns to near its initial level. This innovative feature effectively enhances the simulation of the two-stage firing feel in firearms.

[0018] (3) A simulated two-stage firing mechanism for a firearm can be finely adjusted to change the external dimensions of some components according to the trigger rotation angle and operating dimensions of different firearms, thereby achieving a similar two-stage firing feel. Furthermore, for the same firearm, different two-stage firing feels can be achieved by finely adjusting the dimensions. This mechanism has strong applicability and can be adapted to almost all firearms that are fired by trigger rotation. This innovative feature can greatly reduce the difficulty of achieving the two-stage firing feel for various types of firearms.

[0019] (4) A simulated two-stage firing mechanism for a replica gun has a simple and reliable structure. The mechanism, including the trigger itself and the standard components used, is assembled from nine parts. The main components are the trigger linkage, release torsion spring, firing release spring, trigger top rod seat, and trigger top rod. It features a simple structure and reliable operation. This innovative feature is an effective way to improve the reliability of the mechanism.

[0020] (5) After the simulated firing is completed, each component returns to its original position under the action of the spring. There is no resistance to return, so it is not easy to cause malfunctions.

[0021] (6) During the upward tilting of the front end of the trigger rod seat, since the trigger linkage is a rectangular structure, the rear end of the trigger linkage moves down, and the contact position between its lower front end and the trigger rod pin remains approximately unchanged. The resistance of the release spring remains approximately unchanged, and the time for the release spring to generate resistance can be adjusted according to the height of the trigger rod pin. It can be adjusted according to different firearms and is not limited to a small range of applications. The adjustable range is extremely large, and the simulation is more realistic.

[0029] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] A simulated two-stage firing mechanism for a firearm includes a trigger 9 hinged within the gun body. A trigger spring is mounted on the trigger, acting on both the trigger and the gun body. The mechanism also includes a trigger rod seat 1 and a trigger linkage 6. The trigger rod seat 1 is horizontally positioned in front of the trigger 9 and fixed within the gun body. A forward-extending hinged arm is fixed to the actuating end of the trigger 9, with its front end hinged to the rear end of the trigger linkage 6. The front end of the trigger linkage 6 overlaps the rear end of the trigger rod seat 1. A T-slot is longitudinally provided within the trigger rod seat 1, housing a firing release spring 3 and a trigger rod 4. A firing release spring pin 2 is transversely provided on the trigger rod seat 1, limiting the movement of the front end of the firing release spring 3. The trigger rod 4 is located behind the release spring 3. The trigger rod 4 has a T-shaped cross-section and slides in the T-slot. The two ends of the release spring 3 are connected to the release spring pin 2 and the trigger rod 4, respectively. The trigger rod 4 is provided with a trigger rod pin 5 that extends upward and passes through the T-slot. The trigger rod pin 5 is located in front of the trigger link 6. Under normal conditions, there is a gap between the trigger link and the trigger rod pin. The upper rear end of the trigger rod seat 1 is provided with a clearance notch. The clearance notch is used to make way for the hinge arm of the trigger 9 and the hinge end of the trigger link 6. The front end of the clearance notch forms a fulcrum that causes the front end of the trigger rod seat 1 to tilt upward. The upward tilting process of the front end of the trigger rod seat 1 can be achieved through the trigger rod pin 5.

[0031] The front end of the trigger 9 hinge arm is hinged to the rear end of the trigger link 6 via the trigger link pin 7. A release torsion spring 8 is fitted on the trigger link pin 7. The two ends of the release torsion spring 8 act on the trigger 9 hinge arm and the trigger link 6 respectively. Under the action of the release torsion spring 8, the front end of the trigger link 6 rests downward on the rear end of the trigger top rod seat 1. The spring force keeps the trigger link 6 always inclined downward, thus keeping it in close contact with the lower mechanism and reducing the likelihood of malfunction.

[0032] The two ends of the release spring 3 are welded or sleeved to the release spring pin 2 and the trigger rod 4, respectively. The trigger rod pin 5 is inserted and fixed onto the trigger rod 4.

[0033] A working method of a simulated two-stage firing mechanism for a simulated gun:

[0034] When trigger 9 is pulled, trigger 9 is resisted by trigger spring. Trigger 9 pushes trigger linkage 6 forward through hinge arm until trigger linkage contacts trigger push pin.

[0035] Continue pulling the trigger, and the trigger linkage 6 pushes the trigger push rod 4 forward through the trigger push rod pin 5, which compresses the firing release spring 3. At this time, the trigger 9 is resisted by the trigger spring and the firing release spring 3, realizing the step-by-step increase of the trigger force, and simulating the interaction between the trigger and the bolt.

[0036] Continue pulling the trigger, using the front end of the notch as a fulcrum, the trigger 9 hinge arm drives the rear end of the trigger linkage 6 to move downward, and the front end of the trigger top rod seat 1 tilts upward until the front end of the trigger top rod seat 1 passes the trigger top rod pin 5. At this time, the trigger top rod seat 1 disengages from the trigger top rod pin 5, and the trigger top rod 4 resets under the action of the firing release spring 3, reducing the trigger force jump and simulating the feel of the sear releasing the hammer.

[0037] Specifically:

[0038] In the initial state, such as Figure 2 As shown, there is a gap between the trigger linkage and the trigger top pin. The trigger is acted upon by the trigger spring. When the user pulls the trigger, the trigger spring provides a reverse rotational torque, resulting in smooth force application.

[0039] When the trigger linkage moves forward until it contacts the trigger push pin, as Figure 3 As shown, as the trigger linkage continues to move forward, it pushes the trigger rod, which is equipped with the trigger pin, and the resistance will instantly increase the spring force of the firing release spring, thus achieving a step-by-step change in trigger force.

[0040] Pull the trigger to Figure 4 At the indicated position, the trigger lever seat interacts with the trigger linkage, gradually tilting upwards. At this position, the interaction between the trigger lever seat and the trigger lever pin is lost, and the trigger lever returns to its original position under the action of the release spring. The trigger force instantly decreases, returning to near its initial state.

[0041] The simulated two-stage ignition mechanism of the aforementioned firearm provides a more realistic and detailed simulation of the feel. Through the mechanical transmission between related structures, it constructs a simulated firearm handling feel, providing users with a better shooting experience when pulling the trigger. When the user's finger contacts the trigger and slowly pulls it back, the trigger initially transmits a stable rotational torque, with the force increasing slightly but remaining almost constant. Upon reaching the initial point of interaction between the trigger and the mechanism, the trigger force instantly increases in a step-like manner. At this point, the user can understand the trigger's firing stroke based on the feel transmitted by the trigger, simulating the interaction between the trigger and the internal "bolt" of the firearm. As the user continues to pull the trigger, the trigger force steadily and continuously increases until, at the "firing" position, the trigger force experiences a sudden drop, simulating the instantaneous feel of the "sealer" releasing the "hammer" in a firearm. Finally, the trigger force returns to near its initial level. This innovative feature effectively enhances the simulation of the two-stage ignition feel of a firearm.

[0042] 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.
