System for controlling electric motion gun

The present invention relates to an electric gun control system for controlling an electric gun used in a survival game or the like as an electric gun control system.

In general, combat games using simulated firearms have been popular recently. The game, which is commonly referred to as a survival game, is said to have originated from a mock battle in which allied countries, such as Europe and the United States, commemorated the victory of World War II.

This survival simulation firearms game is highly regarded as a report because it has a high level of concentration, stamina, team spirit, and brain fighting for survival.

Usually, an electric gun means a gun that uses electricity as a power source, and it is used in various fields, but it is often used in the survival games mentioned above.

Since these electric guns are also equipments and devices, they must be maintained for a long time to be used for a long time. If the typical matters related to the maintenance of electric guns are the maintenance of elasticity of batteries, home-up rubber, magazines, It can be said to be the elastic maintenance of the gearbox spring, the indiscriminate triggering of the non-loaded state.

In general, the electric gun for survival games is manufactured to reproduce the design of the actual gun as it is, and the motors and the battery for driving therein are standardized in the regulations regulating the power of the electric gun. For example, electric guns of rifle models such as the M4, G36C, MP5 series, etc., typically use 9.6V or 8.4V batteries to drive the motor.

Since the electric gun, which is widely used for survival games, is a method in which the piston is instantaneously operated against the cylinder using a motor operated in conjunction with trigger operation to generate compressed air, thereby firing arsenal, controlling the piston of the electric gun is most important. .

Hereinafter, the main configuration of the electric gun 100 to which the present invention is implemented will be described first to help understanding of the present invention.

Referring to Figure 1, there is a stock 1210, also called a butt, in the electric gun 100 according to the present invention.

In addition, there is a barrel cover 1220 (also referred to as a hand guard) at the front, and the battery 110 (BATT) is stored at the bottom of the barrel cover 1220. In general, the survival game electric gun 100 is manufactured to reproduce the design of the real gun as it is, and the motor 140 and the driving battery 110 embedded therein are standardized in the regulations regulating the power of the electric gun 100. . For example, the electric gun 100 of the rifle model, such as the M4, G36C, MP5 series, etc., typically uses a battery 110 of 9.6V or 8.4V to drive the motor 140.

In addition, there is an outer barrel 1230 in the center of the barrel cover 1220, and an inner barrel 1240 is positioned therein to be provided.

In addition, there is a delta ring (1250) to securely fix the middle part.

And there is a hop-up (1260) in the center of the body near the delta ring (1250), the hop-up (1260) serves to increase the range by applying a reverse rotation to the bullet being fired.

In addition, there is a trigger 1100 for triggering, and a magazine 1600 in which baboons, etc. are loaded is mounted in front of it.

And inside the handle 1270 is a motor 140, 1280 for generating power of the electric gun 100, the motor 140 shaft (without sign) to transmit the power of the motor 140, 1280 The first gear 1291 and the second gear 1292 and the third gear 1293 that are interlocked by interlocking the driving gear (not shown) in the interlock are interlocked.

Accordingly, when the motors 140 and 1280 are driven, power is transmitted to the third gear 1293, and at the same time, as the third gear 1293 is rotated, the piston 1300 is pulled in the rear direction, and the piston 1300. Simultaneously, when this is pulled, the turret plate 1310 is also pulled in the rearward direction, and since such configurations are already known, detailed drawings and descriptions will be omitted.

And other configurations such as the chamber 1320, the nozzle 1330, the cylinder 1340, the cylinder head 1345, etc., will be described below in the process of explaining the operation of the electric gun 100, and the above-described chamber 1320 ) And the nozzle 1330, the cylinder 1340, the cylinder head 1345, and the like are already known, and thus detailed drawings and descriptions will be omitted and described.

Hereinafter, the electric gun control system using the MOSFET trigger circuit 130 of the present invention will be described.

The electric gun control system using the MOSFET trigger circuit 130 of the present invention may include the electric gun 100 and the power line communication terminal 200 as illustrated in FIG. 2.

The electric gun 100 of the present invention may include a battery 110, a power line communication modem 120, a trigger module 150, a motor 140, and a MOSFET trigger circuit 130 as shown in FIG. have.

The battery 110 may be implemented with a lithium ion battery pack or the like. The lithium ion battery pack includes at least one lithium ion cell to supply a voltage for driving the motor 140 of the electric gun 100. Here, considering that the motor 140 of the conventional electric gun 100 providing normal power has a rated voltage of 9.6V or 8.4V, the lithium ion battery pack includes three lithium ion cells connected in series with each other. It is desirable to provide a nominal voltage of 11.1V.

The triggering module 150 is provided with a triggering gear (gear 3) that moves the piston to trigger bullets such as baboons. When describing an example of the operation of the trigger module 150, for example, the motor 140 supplied with power from the battery 110 starts to drive. Therefore, the driving gear on the motor 140 axis of the motor 140 rotates the first gear 1291. Next, the second gear 1292 is rotated by the first gear 1291, thereby interlocking the third gear 1293 engaged with the second gear 1292.

As the third gear 1293 rotates, the piston 1300 is pulled back. At the same time, while reciprocating in the forward and backward direction, the tupet plate 1310, which functions to push the bullet into the chamber 1320, starts pulling back. Therefore, the tupet plate 1310 is pulled, and the pulling force is released by a protrusion (not shown) at a point, and then moves forward.

In addition, when the toothless portion of the third gear 1293 reaches the interlocking point of the piston 1300, the piston 1300 pulled by the third gear 1293 is no longer obstructed and the pulling force is lost. The piston 1300 moves rapidly while moving forward.

Accordingly, the air compressed in the piston 1300 is blown through the nozzle 1330 and the cylinder head 1345 is advanced forward, and the nozzle 1330 at the end of the cylinder head 1345 is the top of the chamber 1320. The upper bullet (Bittan) is seated on the rubber (not shown) in the hop-up 1260. And these processes are performed almost instantaneously at the same time, and the bullet is fired by the force of the compressed air of the piston 1300 that is instantaneously ejected through the nozzle 1330 at the moment when the last process is completed. And in the case of continuous shooting, this operation is repeated 14-20 times per second.

The MOSFET trigger circuit 130 is a circuit provided with a MOSFET that controls rotation of the trigger gear that moves the piston to trigger. In addition, a plurality of capacitors and diodes are provided to stably provide the voltage of the battery 110 to the motor 140 and the triggering module 150.

As is known, a MOSFET is a field effect transistor, and is a device that controls a current (Id) flowing through a drain-source with a gate-source voltage difference (hereinafter Vgs). However, since the output Id is greatly changed even by a slight error of Vgs, the MOSFET is practically used as a switching element such as blocking Id by making it 0 at all or opening Id to infinity. In addition, the MOSFET (MOSFET) has the advantage of being able to perform switching at high power with low power, without arc / chattering, at low heat / high speed, and without being consumed to maintain the ON state compared to a typical transistor. By using these MOSFETs to replace the contact contact type switch of the existing electric gun 100, it prevents sparks and suppresses noise such as voltage spikes and surges, ultimately causing potential damage to the motor 140 and the battery 110 Can be prevented.

Also, the MOSFET has a P channel and an N channel, which are devices having opposite current flow directions. By using both of these, power is supplied to the motor 140 to rotate, and on the contrary, a reverse current is applied to the rotating motor 140 to rapidly brake the motor 140. This is called Active Breaking, and through this, the third gear 1293 of the electric gun 100 can be accurately stopped at a desired position. Therefore, it is possible to pre-pull by pulling the piston in advance through this, so that the next firing can proceed quickly, and in conjunction with detecting the rotational angle of the third gear 1293 and detecting the position of the selector, the desired number of dots and magazine detection sensors are connected. It is possible to limit the number of shots per magazine as many as you want, and the sniper mode that allows you to fire only at a fixed time interval associated with the internal clock counter.

In addition, if the power supply to the motor 140 is continued several times for a short time with a MOSFET, a special beep-beep sound is generated from the motor 140 according to the time interval, through which a low voltage alarm, magazine consumption alarm, etc. , It becomes possible to transmit a signal to the user.

The power line communication modem 120 is a module that is connected to a battery and receives a voltage to be delivered to a MOSFET as shown in FIG. 3. Alternatively, the power line communication modem 120 performs power line communication with the power line communication terminal 200 when the power line communication terminal 200 is connected instead of the battery 110 as shown in FIG. 4.

Power Line Communication (PLC), as is known, refers to a technology that can transmit voice, text data, video, etc. by connecting to a high-speed Internet and a telephone using only an electric outlet, that is, a power line. That is, as a communication technology that can use voice, data, and the Internet at a high speed as a power line, a data transmission path divided into TV, telephone, and optical communication becomes possible with one power line. It is used in various fields. Therefore, the electric gun 100 of the present invention can transmit and receive necessary data to and from an external communication terminal through the power line communication modem 120.

The power line communication terminal 200 is a terminal that is connected to the power line communication modem 120 from which the battery 110 is removed, as illustrated in FIG. 4, and controls the operation of the MOSFET through power line communication. In the drawings, a desktop PC is described as an example, but not only a desktop PC, but also a smart phone, a tablet PC, a slate PC, a notebook computer, and a terminal for digital broadcasting. PDA (Personal Digital Assistants), PMP (Portable Multimedia Player), navigation (Navigation), digital camera (Digital Camera), MP3P (MPEG layer 3 Player) may be applicable. Of course, the terminal to which the present invention is applicable is not limited to the above-described types, and it is natural that it can include all terminals capable of communicating with external devices.

The power line communication terminal 200 transmits the control value of the MOSFET trigger circuit 130 to the MOSFET trigger circuit 130 through the power line communication.

In addition, the power line communication terminal 200 receives and displays the state information of the electric gun 100 from the MOSFET trigger circuit 130 through the power line communication. Here, the state information of the electric gun 100 includes a trigger rotation angle detection value, a selector position detection value, a magazine insertion detection value, a battery 110 voltage detection value, and the trigger rotation angle detection value is an optical sensor Or it can be detected through the Tact switch.

Therefore, the following technology can be implemented using the power line communication terminal 200 that performs power line communication.

1) User programming in connection with power line communication

The battery 110 of the MOSFET trigger circuit 130 is removed from the connector of the plug, and a PC and an additional terminal are plugged in place to customize the MOSFET trigger circuit 130 to the user's taste through power line communication. After the power line communication terminal 200 cuts off the power that enters the MOSFET trigger circuit 130 for a whole time of 100us to 500us, and measures the blocked time in the MOSFET trigger circuit 130 to measure the number from 0 to 9. It is a method of obtaining, and at this time, the actual power supply to which the MOSFET trigger circuit 130 operates is continuously supplied through the capacitor and the diode without being disconnected.

This can be applied in the same way, and the transmission from the MOSFET trigger circuit 130 to the power line communication terminal 200 is also possible. At this time, since the signal sent by the user returns to the other party as well as to the other party, the protocol including the sender is transmitted. You can apply to get only the information you need.

In addition, when a high voltage battery 110 such as 7.4v, 11.1v, etc. enters instead of the power line communication terminal 200, it is protected from entering a high voltage through the zener diode so that high voltage does not enter the power line communication. Both the actual use after plugging the battery 110 into two lines and the customization through the power line communication modem 120 are possible.

2) Obtaining information for electric gun control

The MOSFET trigger circuit 130 is a circuit that ultimately controls the rotation of the motor 140, that is, the rotation of the third gear 1293, which is a trigger gear that moves the piston. For this control, the MOSFET trigger circuit 130 collects the most important information to detect the rotation angle of the third gear 1293, and in addition, detects the rotation angle of the trigger, detects the selector position, detects whether the magazine is inserted, detects the battery ( 110) Voltage detection, etc. can be performed for analysis and application.

Most of these are performed by light sensing. In particular, the trigger can also be used by light sensing, but a Tact switch can be applied instead of a light sensor to take advantage of the mechanical “click” feeling.

Meanwhile, when power is supplied to the circuit, the circuit continuously consumes the power. At this time, if the power source was the battery 110, an accident due to over-discharge may occur. However, if the circuit can easily cut off the power supplied to it, the battery 110 can be safely used without removing the battery 110 from the circuit. Accordingly, the electric gun control system using the MOSFET of the present invention is provided with a separate power cut-off circuit. It will be described with reference to FIGS. 5 to 7 below.

5 is an exemplary illustration between shooting adjustments according to an embodiment of the present invention, FIG. 6 is a diagram showing a state in which a reed switch is switched off according to an embodiment of the present invention, and FIG. 7 is an embodiment of the present invention. Therefore, the reed switch is switched on.

The electric gun control system using the MOSFET of the present invention includes a shooting adjustment interval, a selector plate 10, a magnetic sticker 11, and a reed switch 131.

The shooting adjustment interval is an adjustment interval in which the safety mode, the continuous shooting mode, and the firing mode are displayed as shown in FIG.

The selector plate 10 is a plate that is switched to any one of a safe mode, a continuous firing mode, and a firing mode, as shown in FIG. 5, to select a triggering mode.

The reed switch 131 is provided inside the shooting adjustment at the point where the safety mode is displayed, and switches to turn off the power when magnetic force is applied.

The magnetic sticker 11 is a sticker attached to the selector plate 10 and is a sticker containing a magnetic material.

The reed switch 131 is provided inside the shooting adjustment of the point where the safety mode is displayed, and switches to turn off the power when magnetic force is applied.

As described above, a magnetic sticker, which is a special sticker attached to the selector plate 10, is provided. In addition to the black and white two-tone markings to be used to lightly sense the position of the selector plate 10, the magnetic sticker 11 is a small magnet. It is attached and has magnetism. Therefore, when the selector plate 10 to which the magnetic magnetic sticker 11 is attached is moved to the safe mode (SAFE) position, the reed switch 131 responding to the magnetic field in the MOSFET trigger circuit as shown in FIG. 6 is cut off. Cut off the logic power. As a MOSFET device that directly draws power from the battery 110, not a logic power source, there is no current consumed when ON and OFF are maintained, and consequently, the battery 110 usage in all ranges is' 0; Of course, when the selector plate 10 is moved back to the triggering mode (SEMI) or the triggering mode (AUTO), as shown in FIG. 7, the reed switch 131 reacts to a magnet that is close to the contact, and the MOSFET trigger circuit Power is supplied.

The above-described embodiments in the description of the present invention are selected and presented in order to assist the skilled person in understanding among various practical examples, and the technical spirit of the present invention is not necessarily limited to or limited by these embodiments. , Various changes and modifications and equivalent other embodiments are possible without departing from the technical spirit of the present invention.
