Description

Mine rifle reaction force generating device {Device of generating reaction in sham rifle}

The present invention relates to a reaction force generating device of the simulated firearm, and more particularly, to a simulated rifle reaction force generating device configured to generate a reaction force to the rear of the butt plate of the simulated rifle at the moment of triggering.

The simulated firearms used in the shooting training of the military, police, or shooting ranges are supposed to react by shooting laser beams from the muzzle on the screen where the target is displayed. This means that when the user pulls the trigger, the controller provided inside the gun operates the laser generating means to irradiate the laser light to the target area to align the target equipped with the sensor.

However, the conventional simulated firearm does not generate a reaction force in the firearm even when the trigger is pulled, so that the actual fire does not appear, and especially when shooting, the aiming point is not disturbed, and thus it is not helpful for the actual fire drill.

The present invention was created to solve the above problems, and simulates a realistic shooting practice by providing a sense of actual shooting by generating a reaction force of the rear when the trigger of the rifle is pulled by using the pressure of the compressed gas The aim is to provide a rifle reaction force generator.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing for explaining the concept of the simulated rifle reaction force generating device according to the present invention.

Basically, the simulated rifle 10 of the present invention is connected to the pump 16 by a hose 14 and is configured to operate by force by the compressed gas generated from the pump 16. Inside the butt plate 12 of the simulated rifle 10, reaction force generating units 19, 49, and 69 described later are incorporated. The reaction force generators 19, 49, and 69 operate by pulling the trigger 18 of the simulated rifle 10 to apply a reaction force of the rear to the buttboard.

In addition, inside the simulation rifle 10, a laser beam generating means (not shown) and a controller (not shown) for controlling the laser beam generating means are installed as in the conventional simulation gun.

2 is a view showing a simulated rifle reaction force generating device according to a first embodiment of the present invention.

Referring to the drawings, the simulated rifle reaction force generating device according to the present embodiment is connected by the pump 16 and the pump 16 and the hose 14 and operates in the butt 12 to generate a reaction force in the rear direction. It comprises a reaction force generating portion 19 to generate.

The reaction force generating unit 19 is fixed to the butt plate 12 by a fixing pin (32). The fixing pin 32 penetrates both side surfaces of the butt plate and the reaction force generating unit 19 to fix the reaction force generating unit 19 to the butt plate 12. Therefore, the reaction force generated inside the reaction force generating unit 19 is to be transmitted to the butt plate 12 through the fixing pin (32).

The reaction force generating unit 19 is provided with a piston 26 therein and a cylinder 24 having both ends closed, a solenoid valve 38 for opening and closing a flow path for pressurizing compressed gas into the cylinder 24; It is configured to include a controller 40. The solenoid valve 38 is opened by the controller 40 so that the compressed gas generated by the pump 16 is pressurized into the cylinder 24 through the hose 14. The solenoid valve 38 is a normally closed valve which is always closed while there is no electric signal.

In addition, the controller 40 is connected with a trigger and a signal line (not shown) to operate the solenoid valve 38 by receiving a signal by the trigger (18 in FIG. 1).

The cylinder 24 is horizontally installed in the longitudinal direction of the rifle, the front end is provided with a front cap 20, the rear end is provided with a rear cap 22. The front cap 20 and the rear cap 22 seal the cylinder 24 to the outside. In addition, the fixing pin 32 penetrates the front cap 20 and the rear cap 22 to fix the cylinder 24 to the butt plate 12.

A vent hole 29 is formed at a portion corresponding to the front surface of the rear cap 22 of the cylinder 24. The vent hole 29 is a hole provided to allow gas inside to escape when the piston 26 moves toward the rear cap 22, as will be described later.

On the other hand, the front cap 20 has a guide hole 34 is formed. The guide hole 34 is a hole formed horizontally through the center of the front cap 20 and is connected to the hose 14. In addition, the inside of the guide hole 34 is provided with a push rod 36 to reciprocate. Therefore, the compressed gas pressurized into the guide hole 34 through the hose 14 moves the piston 26 while pressing the push rod 36 in the direction of arrow a, and the piston 26 by the restoring force of the spring 28. When it is home, it slides in the opposite direction of the arrow a direction.

The piston 26 provided in the cylinder 24 is slidable in an airtight state with the inner circumferential surface of the cylinder 24. For this airtightness, a lubricant may be applied between the outer circumferential surface of the piston 26 and the inner circumferential surface of the cylinder 24.

As described above, the piston 26 is a member that strikes the rear cap 22 by moving in the direction of arrow a in response to the pressing force of the push rod 36. In fact, since the operation of the solenoid valve 38 is instantaneous and the pressing force of the compressed gas is provided very strongly, the opening of the solenoid valve 38 causes the piston 26 to move momentarily quickly. A mounting groove 30 is formed at the center of the rear side of the piston 26, and a mounting groove 30 is also formed at the center of the rear cap 22 facing the mounting groove 30. The mounting groove 30 is a groove provided for installing the spring 28 between the piston 26 and the rear cap 22. In addition, since both ends of the spring 28 are installed in the mounting groove 30, even if the piston 26 is completely moved toward the rear cap 22 to be in contact with the rear cap 22, it is hindered by the spring 28. It doesn't work. That is, when the piston 26 hits the rear cap 22, the spring 28 is compressed to be located inside the mounting groove 30, so that the hitting surface 60 of the piston 26 is without any interference with the rear cap ( 22).

The spring 28 functions to move the piston 26 in the opposite direction of the arrow a direction after the strike of the piston 26 to restore the original position. In other words, by the restoring force of the spring 28, the piston 26 and the push rod 36 are positioned in the original position before operation.

The reaction force generating device of this embodiment as described above has a structure suitable for single shot. That is, when the trigger is pulled once, the controller 40 sends an electric signal to the solenoid valve 38 once to open the valve 38 and causes the push rod 36 to move the piston 26 to generate reaction force. Later, the piston 26, the push rod 36 and the solenoid valve 38 are to be restored to the initial position to wait for the next trigger.

3 and 4 are diagrams for explaining the operation of the simulated rifle reaction force generating device according to the first embodiment of the present invention.

3 is a view showing a state before the trigger is pulled.

Referring to FIG. 3, it can be seen that the solenoid valve 38 is a valve which is always closed by its own spring in a state in which no signal is received. Therefore, even if the pump 16 operates, the compressed gas of the pump does not pass through the solenoid valve 38. In other words, the pump 16 may always be operated in order to use the simulated rifle reaction force generating device of the present invention.

The controller 40 connected to the solenoid valve 38 has a function of operating the solenoid valve 38 in addition to the function of controlling the laser generating means of the conventional mock rifle. In addition, the solenoid valve 38 is configured with a sensor (not shown) for detecting the pull of the trigger to generate the detected content. Therefore, when the trigger is pulled, the controller 40 can detect the fact and at the same time supply the electrical signal to the solenoid valve 38 to operate the solenoid valve 38.

The piston 26 provided in the cylinder 24 is spaced apart from the rear cap 22 by a spring 28, and the push rod 36 also stands inside the guide hole 34. have. At this time, it is preferable that the push rod 36 and the piston 26 are positioned in contact with each other. The end of the hose 14 is inserted into the guide hole 34 is coupled as described above. In addition, it can be seen that the vent hole 29 is formed in the cylinder corresponding to the space between the piston 26 and the rear cap 22.

As shown in FIG. 4, when the trigger (18 in FIG. 1) is pulled as described above, the controller 40, which detects the pull of the trigger 18, sends an electric signal to the solenoid valve 38. Therefore, the solenoid valve 38 is opened and the compressed gas moves to the guide hole 34 by the hose in an instant, pressurizes the push rod 36 to move the piston 26 to the rear cap 22 side, and the piston 26. The hitting surface 60 of the hitting the opposite surface of the rear cap 22 to generate a reaction force. At this time, the internal gas between the piston 26 and the rear cap 22 exits through the vent hole 29 to the outside.

The movement of the piston 26 as described above is made by a single trigger of the trigger. That is, when the trigger is pulled once, the controller 40 automatically operates the solenoid valve 38 once and automatically returns to the standby state. Since the solenoid valve 38 is dependent on the operation of the controller 40, the solenoid valve 38 is also opened and closed again according to the one-time operation of the controller 40, and waits in the closed state until the trigger is pulled again. The opening time per solenoid of the solenoid valve 38 is preset by the controller 40. In general, the higher the pressure of the compressed gas, the shorter the opening time of the solenoid valve 38 can be.

Since the solenoid valve 38 is closed after the piston 26 moves to generate the reaction force as described above, the force of the compressed gas applied to the piston 26 is lost, and the piston 26 is connected to the spring 28. It moves to the initial position by the restoring force. When the trigger is pulled again in this state, the reaction force is generated again as shown in FIG. 3.

5 is a view for explaining the structure of a simulated rifle reaction force generating device according to a second embodiment of the present invention.

The same reference numerals as the above reference numerals denote the same members having the same function.

The reaction force generating device according to the present embodiment is configured to supply compressed gas to both sides of the cylinder.

Referring to FIG. 5, the simulated rifle reaction force generating device according to the present embodiment includes a reaction force generating unit 49 connected to a pump 16 and the pump 16 and a hose 14 to receive compressed gas. . The reaction force generating unit 49 reciprocates back and forth in the cylinder 56, the front cap 42 and the rear cap 44 fixed to both ends of the cylinder 56, and the inside of the cylinder 56 And a piston 54.

In addition, a guide hole 46 is formed in the central shaft portion of the front cap 42 and the push rod 50 is provided in the guide hole 46 to be slidable. Similarly, a guide hole 48 is formed in the rear cap 44, and the push rod 52 is provided to be slidable in the horizontal portion of the guide hole 48. Each of the push rods 50 and 52 is slidable inside each of the guide holes 46 and 48 and is pressed into the cylinder by the pressure of the compressed gas to press the piston 54.

In addition, in the present embodiment, the guide hole 48 of the rear cap 44 takes the form of the letter 'a', of course, the shape may be modified according to the embodiment.

On the other hand, the hose 14 through which the compressed gas generated from the pump 16 flows is bifurcated through the solenoid valve 58 to guide holes 46 and 48 of the front cap 42 and the rear cap 44. Connected. Since the solenoid valve 58 is controlled by the controller 40, the compressed gas generated from the pump 16 passes through the solenoid valve 58 and is changed in direction to determine the moving direction of the piston 54.

6 and 7 are views for explaining the operation of the simulated rifle reaction force generating device according to a second embodiment of the present invention, Figure 6 is a state in the normal standby state without the trigger is pulled, Figure 7 is a trigger Figure is a view showing a state that occurs when the pull.

Referring to FIG. 6, it can be seen that the compressed gas generated from the pump 16 moves to the guide hole 48 of the rear cap 44 along the arrow d direction through the solenoid valve 58. The solenoid valve 58 applied to the present embodiment is a well-known four-port two-position switching valve, in which an internal flow path is reversed when there is an external signal and when there is no external signal. When there is an external signal, it is switched to the first position, and as in FIG. 7, and when there is no external signal, it is switched to the second position and as in FIG.

Since the compressed gas is pressed into the guide hole 48 as described above, the push rod 52 maintains the state in which the piston 54 is pressed in the direction of the arrow c. Therefore, when the pressure of the compressed gas in the direction of the arrow is stronger or the inside of the guide hole 46 of the front cap 42 is a vacuum situation, the piston 54 may reach the opposite surface of the front cap 42. In addition, this state is a state in which the gas in the internal space of the guide hole 46 is vented to the outside through the solenoid valve 58.

When the trigger is pulled in the standby state as described above, the controller 40 senses that the trigger is pulled and sends an electric signal to the solenoid valve 58. The solenoid valve 58 receiving the electric signal is switched to the first position so that the compressed gas that provides the pressing force in the direction of the arrow d is switched in the direction of the arrow e to pressurize the push rod 50 provided in the front cap 42. At the same time, the pressure of the compressed gas reaching the guide hole 48 of the rear cap 44 is vented to the outside through the solenoid valve 58.

Compressed gas moving in the instant along the direction of the arrow e pressurizes the push rod 50 to move the piston 54 toward the rear cap 44 at a high speed. Therefore, the impact surface 60 of the piston 54 hits the opposite surface of the rear cap 44 is generated a reaction force.

One such operation is achieved by pulling the trigger once. That is, when the trigger is pulled once, the controller 40 detects the movement of the trigger and automatically transmits the electric signal to the solenoid valve 58 for a set time. Therefore, the piston 54 moves while the electric signal is transmitted to generate a reaction force, and when the electric signal is blocked, the piston 54 is returned to the standby position as shown in FIG. At this time, if a continuous electrical signal is applied to the solenoid valve 58, the continuous shooting can be implemented.

8 is a view for explaining the configuration of a simulated rifle reaction force generating device according to a third embodiment of the present invention. The simulated rifle reaction force generating device according to the present embodiment has a structure further bonded to the continuous rifle. That is, it has a structure in which reaction force is continuously generated while the trigger is being pulled.

In the reaction force generating section 69 of the present embodiment, unlike the first and second embodiments, the compressed gas is delivered to the piston 64 through the center of the cylinder 62 body, and the supply port 76 is provided at the center. A cylinder 62 having a first and second vent holes 70 and 72 formed therein, a front cap 78 and a rear cap 80 which close and seal both ends of the cylinder 62; A piston 64 reciprocating in the cylinder 62 and a spring 82 provided between the piston 64 and the rear cap 80. A hose 14 is connected to the supply port 76, and a solenoid valve 74 is provided in a flow path of the hose 14.

The solenoid valve 74 is connected to the pump 16 and the hose 14 and is operated by the controller 40 to supply the compressed gas of the pump 16 to the supply port 76. Here, the controller 40 generates a signal as the trigger is pulled, and is configured to continuously generate an electric signal, especially while the trigger is pulled. Thus, the flow of compressed gas through the solenoid valve 74 continues while the trigger is pulled. When the trigger is released, the signal from the controller 40 is blocked and the solenoid valve 74 is also blocked.

In the center portion of the cylinder 62, a supply hole 76, which is a through hole, is formed. The supply port 76 selectively communicates with the first passage 66 and the second passage 68 formed in the piston 64 as a hole into which the compressed gas is pressurized. For this purpose, a groove 84 is formed in the inner circumferential surface of the cylinder 62 in which the supply port 76 is formed. The groove 84 is formed along the inner circumferential surface of the cylinder 62 and thus will take the form of an annular groove if the cylinder 62 is cylindrical. The groove 84 is a space provided for injecting compressed gas into the second flow passage 68 whose inlet 71 is formed on the opposite side of the supply port 76.

In addition, the first and second vent holes 70 and 72 formed in the cylinder 62 are opened and closed by the piston 64 and have a separation distance longer than the length of the piston 64. Therefore, the first vent hole 70 and the second vent hole 72 are selectively opened according to the movement of the piston 64 without being blocked at the same time. The selective opening means that the first vent hole 70 is blocked and the second vent hole 72 is opened while the compressed gas is pressurized into the first passage 66 as shown in FIG. 9, and as shown in FIG. 10. As the piston 64 moves toward the rear cap 80, the first vent hole 70 is opened while the second vent hole 72 is blocked while the second passage 68 is opened.

On the other hand, a spring 82 is installed between the piston 64 and the rear cap 80. The spring 82 has a shock absorbing action that prevents the piston 64 from hitting the rear cap 80 too strongly. Simultaneously with this function, the piston 64, which has finished hitting, is restored to the front cap 78 side more quickly. In fact, as will be described later, the movement of the piston 64 toward the front cap 78 is made by the pressurization of the compressed gas through the second flow passage 68, so that the spring 82 may be omitted during the restoration.

9 and 10 are diagrams for explaining the operation of the simulated rifle reaction force generating device according to a third embodiment of the present invention.

Referring to FIG. 9, the compressed gas generated in the pump 16 is blocked by the solenoid valve 74 and thus cannot move toward the cylinder 62. The solenoid valve 74 is a valve that is normally kept closed by its own spring and opens when a signal is received from the controller 40.

The piston 64 inside the cylinder 62 is in close contact with the front cap 78 by a spring 82 before the trigger is pulled. In this state, the first flow path 66 communicates with the supply port 76, and the first vent hole 70 is blocked by the piston 64. In addition, the inlet 71 of the second flow passage 68 is blocked by the inner circumferential surface of the cylinder 62 and the second vent hole 72 is opened.

When the trigger (18 in FIG. 1) is pulled to drive the reaction force generating device waiting in the above state, the controller 40 generates a signal according to the movement of the trigger to open the solenoid valve 74. FIG. At the same time, the compressed gas of the pump 16 moves in the direction of the arrow g in an instant and passes through the supply port 76 to exit the outlet 86 of the first flow path 66. At this time, due to the pressure of the compressed gas, the pressure in the inner space between the front cap 78 and the piston 64 increases, so that the piston 64 moves toward the rear cap 80 in the direction of the arrow f and the rear cap 80 Hitting. Gas between the piston 64 and the rear cap 80 exits the second vent hole 72.

Fig. 10 is a diagram showing the next state at the moment when the reaction force is generated.

As shown, when the piston 64 moves to the rear cap 80 side, the inlet 71 of the second flow path 68 is located in the groove 84, and the compressed gas pressurized in the direction of the arrow g is arrow m. It flows through the 2nd flow path 68 along the direction of. Compressed gas exiting the outlet 88 of the second passage 68 is filled in the internal space between the piston 64 and the rear cap 80, and moves the piston 64 in the direction of the arrow p. At this time, the spring 82 is also restored. As described above, when the piston 64 moves, the compressed gas between the front cap 78 and the piston 64 exits to the outside through the first vent hole 70.

When the piston 64 reaches the front cap 78, the first flow path 66 is opened again, so that the piston 64 moves to the rear cap 78 again to generate a reaction force as shown in FIG. Eventually, while the valve 74 is open, the piston 64 in the cylinder 62 continuously reciprocates, and if the trigger continues to be pulled, the reaction force is continuously generated, which can be a practice of continuous shooting.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.

Simulated rifle reaction force generating device of the present invention made as described above is configured to generate a reaction force of the rear of the butt when the trigger is pulled by using the pressure of the compressed gas can feel the actual shooting. Therefore, it is possible to practice realistic shooting practice, and the effect of training is high, and even if it is used for leisure, not for the police or military training, there is an effect that it is possible to actually shoot and especially shot shooting is also possible.
