Description

electric recoil device

The present invention relates to an electric recoil device that can be used in gaming firearms, etc.

As a conventional gaming gun, there were toy-type guns that fired simulated bullets using elastic means or compressed air, and there were sports shooting guns that fired bullets using compressed air and gunpowder but were used for sports shooting in terms of purpose.

Recently, with the development of electrical and electronic technology, a number of gaming guns have been developed and used to fire virtual bullets electronically and optically without using compressed air or gunpowder to fire physical bullets, and to check whether or not they hit the target. there is.

These gaming guns capable of electronic firing and detection have the advantage of eliminating the risk of physical bullet firing and gunpowder explosion in games such as survival games or in mock combat training, but electronic firing and detection alone can It also has the disadvantage of not being able to give the feeling and interest of live shooting because it cannot generate the perceived sense of shooting, such as the feeling of recoil from shooting with live ammunition, noise from explosions and mechanical movements, flashes, and the smell of gunpowder. In particular, in survival games, etc., there were limitations that reduced interest because it was difficult to provide the feeling of real shooting and a sense of reality.

Therefore, in order to solve the problem of existing electronic firing and confirmation of game guns, many methods have been developed and used to artificially generate sensory stimulation so that users can feel the same sensation as when shooting with live ammunition when shooting a game gun. am. For example, game guns or game shooting systems that generate shooting noises such as gunpowder explosions, flashes, and the smell of gunpowder smoke when shooting, and add sound effects when the shot hits a target, have been produced and are being operated.

And, like other devices and systems that reproduce the shooting sensation, a recoil device that implements the gun's recoil when shooting is formed and used in the gun itself. Recoil devices are not limited to firearms that use electronic shooting and sensing, and can also be used to enhance the feeling of recoil in physical shooting.

This gun recoil and hitting sensation can be reproduced mechanically using compressed air, such as shooting an actual bullet, or an elastic body such as a spring, but it can also be reproduced electromagnetically.

Republic of Korea Patent Publication No. 10-2017-0047496 discloses an example of a recoil device. Here, as shown in FIG. 1, the recoil device 310 has an air compressor (311) that generates compressed air, and when receiving the trigger signal, the compressed air supplied from the air compressor (311) is compressed into the body portion (30). ) and a solenoid valve (Solenoid valve, 312) that transmits to the moving space formed inside.

Here, the air compressor 311 is a device connected to the inlet of the solenoid valve 312 through a gas pipe 313, and generates compressed air and supplies it toward the inlet of the solenoid valve 312. The gas pipe 313 may be inserted into the handle portion 40 or may be located outside the handle portion 40 separately.

The solenoid valve 312 is installed on one side of the moving space inside the body 30 and is controlled by turning the switching unit 302 on and off. One side of the solenoid valve 312 is connected to the air compressor 311 through a gas pipe 313, and the other side is electrically connected to the switching unit 302, so that a trigger signal is generated through the on/off of the switching unit 302. It operates by receiving. That is, the solenoid valve 312 opens when the trigger 301 is pulled by the user, allowing compressed air to be supplied from the air compressor 313 through the gas pipe to the moving space inside the body 30.

Accordingly, the recoil device 310 advances the bolt bundle 303 forward by pneumatic pressure by the operation of the solenoid valve 312 according to the percussion signal, and this forward movement generates a recoil backward as in actual shooting. You can do it. At this time, when the solenoid valve 312 is opened by a percussion signal and pneumatic pressure is generated in the moving space, the bolt bundle 303 provided in the moving space inside the body portion 30 moves forward by this pneumatic pressure, similar to actual shooting. Causes recoil. Although not shown here, a spring that moves the bolt assembly 303 may be provided inside the movement space of the body portion 30.

In this example, when the user fires the gun toward the target through the recoil device 310, the solenoid valve 312 attached to the inside of the body 30 of the game gun 10 advances the bolt assembly 303 of the gun and moves it forward. Due to the recoil that occurs when shooting, the user can experience the recoil that can be felt when a bullet is fired from an actual firearm.

When using pneumatic recoil like this, the strength of the recoil can be strengthened to some extent, but if used repeatedly, air leaks can occur at the connection of the air supply pipe, and if used intensively, the air pressure decreases, causing problems in the operation of the entire system. There was a problem.

In addition, the compressor that supplies air pressure to the recoil device must be installed outdoors in consideration of noise. It was very inconvenient to move when moving it for indoor or outdoor events, and the firearm had to be installed in order to withstand strong air pressure. In order to strengthen the parts, heavy materials were increasingly used, making it difficult for gun users such as the elderly, women, and the disabled to use them, making it difficult to expand the public base.

Meanwhile, in the example of the drawing above, it is explained as an example that the recoil force generating unit 310 is operated by interlocking the air compressor 313 and the solenoid valve 312, but the configuration of the recoil device is not limited to this. For example, in order to solve the problem of recoil using pneumatic pressure as described above, when electricity is supplied to the solenoid valve 312 without connecting the air compressor 313, it reciprocates back and forth to generate a shock, and during the back and forth reciprocation, it hits the partition wall and causes recoil. It can also be operated by creating . At this time, the partition wall is provided with a spring (elastic member) so that the striking object can return to its original position.

Republic of Korea Registered Utility Model No. 20-0489516 discloses one specific configuration example of a recoil device. This actuation generator can be installed in the body of the rifle as indicated by the dotted line in FIG. 2, and has the same configuration as the assembled state drawing in FIG. 3 and the disassembled state drawing in FIG. 4. Referring to Figures 3 and 4, here, the recoil device 1100 is installed inside the body of the firearm, and when fired, it can cause a physical collision by electromagnetic force to apply recoil to the firearm. For this purpose, the recoil device 1100 includes a solenoid coil 1110, a coil frame 1120, a guide tube 1130, a first fixing member 1140, a second fixing member 1150, a guide member 1160, and a plunger ( 1170), a first elastic member 1180, and a second elastic member 1190.

The solenoid coil 1110 is fixed in the form of being wound around a core fixed inside the coil frame 1120, and can receive an electrical pulse signal from a power supply through the first and second

electric lines

1111 and 1112. Here, the core around which the solenoid coil 1110 is wound may be made of a non-conductive material such as plastic that does not shield magnetic fields, and the supply power may include a rechargeable secondary battery. This secondary battery can be replaceably coupled to the gun handle. Additionally, the gun handle may be provided with a terminal for charging the secondary battery so that when the secondary battery is discharged, external power can be supplied to the secondary battery for charging. The power supply may apply a pulse signal to the recoil device 1100 under the control of a separate gun control unit. Here, the pulse signal may be output at different voltage levels by the gun control unit.

The coil frame 1120 is a means for fixing and accommodating the solenoid coil 1110 and has a roughly U-shaped shape when viewed from the front view. However, the coil frame 1120 may have various structures to suit the shape of the solenoid coil.

The guide tube 1130 may be formed to penetrate the core for fixing the solenoid coil 1110 and the coil frame 1120. This guide tube 1130 has a predetermined length, and a cross-section perpendicular to its longitudinal axis may have a circular or oval shape depending on the shape of the plunger or the like and necessary circumstances.

This guide tube 1130 may have an extended shape that protrudes to one side and the other side around the coil frame 1120. For convenience, here, one side of the guide tube 1130 refers to the first fixing member 1140 side, and the other side refers to the second fixing member 1150 side, and vice versa.

Here, the space between the coil frames 1120 on one side of the guide tube 1130 is shorter than that between the coil frames 1120 on the other side.

The first fixing member 1140 may be fixed to one opening of the guide tube 1130. This first fixing member 1140 has a substantially cylindrical shape, and a guide member 1160 is fixed to its central portion.

The second fixing member 1150 is coupled to the other opening of the guide tube 1130. To this end, the second fixing member 1150 may include a coupling cover 1151, a fixing protrusion 1152, and a nut 1153.

The coupling cover 1151 may be formed to cover the other opening of the guide tube 1130, may be formed with or without a cavity therein, and may be made of a metal material. A step portion that can be firmly inserted into the other opening of the guide tube 1130 is formed between the coupling cover 1151 and the fixing protrusion 1152.

The fixing protrusion 1152 protrudes from the step portion of the coupling cover 1151 so that one side of the second elastic member 1190 in the form of a coil spring can be inserted and fixed.

The guide member 1160 may extend from the first fixing member 1140 along the guide tube 1130 and be coupled to the second fixing member 1150. More specifically, one side of the guide member 1160 is fixed to the first fixing member 1140 and passes through the core of the solenoid coil 1110 and penetrates the second fixing member 1150. ) and can be combined with bolts. For this purpose, a bolt portion with a thread is formed at the end of the guide member 1160, and this bolt portion is exposed through the second fixing member 1150, and the exposed bolt portion is fastened with the screw 1153, so that the guide member ( 1160) may be firmly coupled to the second fixing part 1150.

A guide member 1160 may be slidably inserted into the central axis hole of the plunger 1170 so that the plunger can move in both directions along the guide member 1160. This plunger 1170 is made of a magnetic metal material, has a predetermined length and weight, and its cross section may be approximately cylindrical to correspond to the internal structure of the cross section of the guide tube 1130.

The plunger is initially biased toward the second fixing member on the guide member, and when an electric signal is applied to the solonoid coil (when current flows), it acts like an electromagnet and pulls the plunger. The plunger moves toward the first fixing member within the guide tube and compresses the first elastic member 1180. When the electrical signal to the solenoid coil is interrupted (current stops flowing), the magnetic field caused by the solenoid coil disappears and the plunger moves toward the second fixing member 1150 by the elastic restoring force of the first elastic member and the second elastic member is compressed. . Next, the plunger returns to its original position where force is balanced by the first and second elastic members. In this process, the movement of the plunger generates an impulse of shooting recoil similar to the retraction and advancement of the bolt caused by the gunpowder explosion when shooting live ammunition.

However, in the conventional recoil device structure as described above, the force that pulls the plunger to one side due to the magnetic field generated by the solenoid coil by an electrical pulse signal is often insufficient compared to the recoil force of live ammunition. For example, when constructing a solenoid coil and peripheral parts that can be installed in a typical rifle structure, due to space limitations, it is difficult to adopt a thick coil wire of sufficient diameter and form the coil diameter and length to a sufficient size, and the generated magnetic field is also difficult to have sufficient strength. It is difficult to have. In addition, it is difficult to supply power to the rifle through wires in an environment where the user moves, such as in a survival game, when supplying power to form a magnetic field. In this case, power is supplied by installing a battery in the rifle. Power supply through a battery is also possible. This may not be sufficient and this may also be a limiting factor in the occurrence of shooting recoil.

Therefore, in order to sufficiently secure the shooting recoil force of existing gaming guns, a configuration that can generate a large recoil force compared to the power supplied within a small space compared to the previously known electric recoil device configuration is required.

Therefore, the purpose of the present invention is to provide an electric recoil device that can generate a sufficiently large and efficient shooting recoil of a firearm in a game gun or shooting system that performs electronic shooting.

The present invention also aims to provide a gaming gun or shooting system equipped with such an effective electric recoil device.

The electric recoil device of the present invention for achieving the above purpose is

It is provided in a gaming gun, and includes magnetic field forming means such as a solenoid coil that receives an electrical signal from a power supply and forms a magnetic field; It is comprised of a plunger that can be moved by receiving force from a magnetic field generated by a magnetic field forming means, and a permanent magnet is installed in the plunger to increase the force that moves the plunger when a magnetic field is formed by the magnetic field forming means. Do this.

In the present invention, in order to efficiently move the electric recoil device, a guide that guides the movement of the plunger can be installed, and the guide moves the plunger in the magnetic axis direction connecting the magnetic field pole NS formed in the magnetic field forming means and the permanent direction of the plunger. The plunger may be configured to move in the same direction or in a direction parallel to the magnetic axis direction and barrel direction of the magnet.

At this time, in the present invention, the magnetic field forming means is installed separately on both sides of the plunger in the moving direction, one side may be configured with a magnetic pole to apply an attractive force to the plunger containing a permanent magnet, and the other side may be configured with a plunger containing a permanent magnet and The stimulus may be designed to exert a repulsive force.

Alternatively, in the present invention, the temporary magnetic field forming means is formed on one side, and a separate permanent magnet different from the permanent magnet of the plunger is installed on the other side (the other side), so that one side is stimulated to exert an attractive force with the plunger including the permanent magnet. It may be configured on one side, and on the other side, a plunger containing a permanent magnet and a magnetic pole may be configured to apply a repulsive force.

In the present invention, the plunger may be entirely made of a permanent magnet, may be made of a permanent magnet combined with a magnetic material, or may be partially made of a material capable of transmitting a magnetic field.

According to the present invention, by installing a permanent magnet on the plunger in a limited space within a firearm in which an electric recoil device is installed, a larger recoil force can be generated compared to the shooting recoil force of existing game guns even when the power supplied to a temporary magnetic field forming means such as an electromagnet is the same. The same shooting recoil force can be generated with less power than before, so when installing a power source in a firearm, the power supply installation space can be reduced or power efficiency can be increased to supply the necessary power for a longer period of time without replacement or recharging. .

According to the present invention, it is possible to generate a large shooting recoil force closer to reality on the premise of a limited space called a firearm and a shooting game system, thereby giving the user a lively feeling similar to shooting with live ammunition and increasing interest in shooting games. .

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

Figure 5 shows one embodiment of the electric recoil device of the present invention.

In this embodiment, the recoil device includes a solenoid coil 1110 as a magnetic field forming means for generating a magnetic field by receiving an electric signal from a power supply, a coil frame 1120 for fixing and accommodating the solenoid coil 1110, and a coil frame 1120. ) and the solenoid coil 1110, a guide tube 1130 coupled to the coil frame 1120, a first fixing member 1140 fixed to one side of the guide tube 1130, and the other side of the guide tube 1130. A second fixing member 1150 fixed to, a guide member 1160 extending from the first fixing member 1140 along the guide tube 1130 and coupled to the second fixing member 1150, a guide member 1160 A plunger 1170' that is inserted and can move over the guide member 1160, and a first elastic member inserted into the guide member 1160 to be positioned between the first fixing member 1140 and one side of the plunger 1170'. (1180), and includes a second elastic member 1190 inserted into the guide member to be positioned between the second fixing member 1150 and the other side of the plunger 1170'. This configuration basically has something in common with the conventional recoil device 1100 as shown in Figure 4.

And in the present invention, the plunger 1170' is provided with a permanent magnet capable of forming its own unique magnetic field. The magnetic axis direction of the permanent magnet is made to be parallel to the direction of the barrel of the firearm in which the recoil device is to be installed.

When an electrical pulse signal is applied to the solenoid coil 1110 by pulling the gun trigger, a magnetic field having N and S magnetic poles as shown in Figure 5 is formed in the solenoid coil 1110, and this magnetic field is provided in the plunger 1170'. The plunger 1170', which was initially positioned biased toward the second fixing member 1150, moves toward the first fixing member 1140 due to the electromagnetic force (magnetic force) generated by interacting with the self-magnetic field of the permanent magnet. That is, opposite polarity magnetic poles are formed at the opposite ends of the solenoid coil 1110 and the plunger 1170', thereby generating a force (attractive force) that pulls each other, and the movable plunger 1170' moves toward the solenoid coil 1110. It moves.

In the past, the plunger 1170 was a simple magnetic material without a permanent magnet, so the magnetic force between the plunger and the solenoid coil was relatively small, but in the present invention, the same strength was applied to the solenoid coil due to the influence of the magnetic field caused by the permanent magnet of the plunger 1170'. Even if the current flows, the electromagnetic force generated by the interaction is further strengthened, and therefore the plunger moves toward the first fixing member with a stronger force.

In this process, the movement of the plunger 1170' is made stronger than before due to the action of the magnetic field of the permanent magnet, and the movement of the plunger 1170', compression of the first fixing member 1180, and the plunger 1170' The shooting recoil created by the interaction with the surrounding members (for example, transmission of impact to the first fixing member) is also felt more significantly.

Meanwhile, when the electrical pulse signal for the solenoid coil 1110 ends, it moves toward the second fixing member 1150 by the restoring force of the first elastic member 1180, compressing the second elastic member 1190, and The shock can be transmitted to the (1150) side. Then, the plunger returns to its original position where the elastic force of the second elastic member and the elastic restoring force of the first elastic member are balanced.

At this time, if the first elastic member is not completely contracted by the plunger moved by the action of the magnetic field, the deformation of the first elastic member due to the plunger increases and the resulting restoring force becomes stronger, resulting in movement of the plunger toward the second fixing member and the plunger Shocks created by interactions with surrounding members may also be felt more strongly.

Figure 6 is an exploded configuration diagram showing a recoil device of another embodiment of the present invention, and Figure 7 is an assembled state diagram showing a state in which the components shown disassembled in Figure 6 are combined but the guide tube and solenoid coil are removed.

Here, compared to the embodiment configuration of Figure 5, there is a difference in that the magnetic field forming means is also installed on the second fixing member 1150'.

The installed magnetic field forming means may be a permanent magnet or an electromagnet. Although not clearly shown in this embodiment, an additional solenoid coil (not shown) is installed in the coupling cover 1151' of the second fixing member 1150', and the solenoid coil 1110 is connected to the additional solenoid coil when the firearm trigger is pulled. It can be thought that a pulse current similar to that flowing in flows, and the electromagnet core metal penetrating the inside of the additional solenoid coil or located close to it becomes a temporary magnet, and one end of the electromagnet core metal protrudes as a fixing protrusion 1152'. .

When pulse current is applied, the magnetic axis direction formed by the additional solenoid coil is the same as the magnetic axis direction by the solenoid coil 1110. Then, as shown in FIG. 7, magnetic poles (S poles) of the same polarity are present in the opposing parts of the plunger 1170' and the second fixing member 1150', so that when the trigger is pulled, the second fixing member 1150' ) and the plunger (1170'), a repulsive force is applied.

In this embodiment, the relationship and interaction between the plunger 1170', the solenoid coil 1110, the first and second

elastic members

1180 and 1190, and the first fixing member 1140 are performed as in the previous embodiment. You can.

Therefore, in this embodiment, compared to the embodiment of Figure 5, the attractive force between the plunger 1170' and the solenoid coil 1110 is added to the repulsive force between the plunger 1170' and the electromagnet by the additional solenoid coil, so that the plunger 1170 ') can be moved toward the first fixing member 1140 as shown in Figure 8 with stronger force, and the resulting shooting recoil can also be increased. In particular, at the beginning when the pulse current is applied, the plunger (1170') is positioned biased toward the second fixing member (1150'), so the magnetic field caused by the additional solenoid coil built in the second fixing member (1150') and the plunger (1170') The interaction (repulsive force) between the permanent magnets can play a more important role in creating a large initial shooting recoil.

Then, when the pulse current stops flowing through the solenoid coil after a certain period of time, the plunger moves toward the second fixing member as shown in Figure 9 by the elastic restoring force of the first elastic member and transmits the impact force to the second fixing member, and then It goes to the initial position, which is the balance point of the elastic restoring force of the first elastic member and the second elastic member.

The embodiment of FIG. 6 can be seen as installing an additional solenoid coil as a means of generating a magnetic field on the second fixing member compared to the embodiment of FIG. 5. However, overall, this still uses a plunger with a permanent magnet and a solenoid coil. There is no difference in that shooting recoil occurs due to interaction between magnetic field forming means (electromagnets). In order to effectively apply the magnetic field of the electromagnet to the plunger 1170' equipped with a permanent magnet, it can be seen that the electromagnets are distributed in front and behind the plunger 1170'.

Therefore, in this accident, the original solenoid coil 1110 on the first fixing member side is removed and the size of the additional solenoid coil (not shown) on the second fixing member 1150' side and the magnetic field generated there are increased to replace the original solenoid coil 1110. It will be appreciated that embodiments replacing the coil 1110 also fall within the scope of the present invention.

As another embodiment of the present invention, instead of forming an additional solenoid coil in the second fixing member 1150' of FIGS. 6 and 7, an additional permanent magnet is installed as a magnetic field forming means in the second fixing member, and the second It can also be assumed that the elastic member 1190 is removed. In this case, it can be seen that the N and S magnetic poles of the second fixing member shown in Figures 6 and 7 are not formed by an additional solenoid coil but by an additional permanent magnet (not shown).

In this case, the plunger is placed in the initial position where the force between the repulsive force between the permanent magnet of the second fixing member and the permanent magnet of the plunger and the elastic restoring force of the first elastic member are balanced, and at this position, when the trigger is triggered, a pulse current is sent to the solenoid. When a magnetic field is formed in the coil, the plunger moves toward the first fixing member due to the interaction between the magnetic field caused by the permanent magnet of the plunger and the magnetic field of the solenoid coil, forming an initial shooting recoil. This is substantially the same result as the occurrence of shooting recoil due to the interaction between the plunger permanent magnet and the solenoid coil according to the configuration of Figure 5, and it can be said that there is no increase in shooting recoil due to the permanent magnet of the second fixing member, and the multi-faceted second elasticity It can be seen that the repulsive force between the plunger permanent magnet and the second fixed member permanent magnet replaces the elastic force caused by the member.

Therefore, after the pulse current flows through the solenoid coil, when the current disappears, the plunger moves toward the second fixing member due to the restoring force of the first elastic member, creating a subsequent shooting recoil, and the repulsion force between the permanent magnets and the first elastic member. The process of returning the plunger to the initial position, which is the balance point of the elastic restoring force, can also be performed similarly to the embodiment of Figure 5.

In this embodiment, compared to the embodiment of Figure 5, the installation of the second elastic member 1190 can be omitted, and in some cases, the movement distance of the plunger 1170', which was limited by the second elastic member 1190, is extended and As a result, you can enjoy the effect of increased shooting recoil.

In the above, the present invention has been described focusing on the illustrated embodiments, but this is merely illustrative, and various modifications may be made by those skilled in the art, and all or part of the above-described embodiments may be modified. It will be understood that may be configured by selectively combining. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.

The present invention, like devices and systems that reproduce the feeling of shooting, is used in a recoil device that implements the recoil of a firearm when shooting at the firearm itself. The recoil device of the present invention is not limited to firearms that use electronic shooting and sensing, but is used in physical shooting. It can also be used to strengthen the sense of recoil.
