Description

[0001] AIMING DEVICE OF GRENADE LAUNCHER [0002]

The present invention relates to an aiming device of a grenade launcher.

The ladder-type scale of the K-201 grenade launcher that is currently operated is mounted on the top of the barrel and is used as a folding type. The arched scale is mounted on the opposite side of the casing, ie, on the left side. Also, if you are not a skilled user you can confuse the ramp scale with the ladder scale.

In this case, each scale is open type, and it is difficult to accurately shoot because accurate origin is not displayed, and the grenade launcher is triggered by aiming with the alignment of the scale and the scale.

The ladder-type scale and the archetype scale are separated from each other. In the case of a relatively short distance, the ladder-type scale is fired after aligning the line of sight and the line of sight which is used for normal shooting, and manually changing the distance angle displayed on the arc scale You can shoot behind the scales behind the arc scale and align the scales.

The arched scales are difficult to aim because the aperture is small and the scales are thin, and it is difficult to obtain a sufficient field of view with a small hole on the scale.

When aiming in the above-described order, since the aiming order is complicated, rapid aiming shooting may be difficult during the operation, and it is difficult to respond promptly. For example, when you find a target and modify an arc shape, you look at the numerical scale of the archetype scale, adjust it, and then look at the target again. If the target is not a fixed target, then the target disappears from the field of view, It is difficult to respond promptly.

In the case of the conventional ladder-type scale and archetype scale, since the distance measurement is made by the naked eye, the accurate shooting distance can not be known, and there is no device for checking the left, right and horizontal positions of the firearm. When the angle is changed to the left or right, it is difficult for the grenade to reach the target point exactly.

In addition, the existing archetype and ladder-type scales can easily be damaged during the training process. In the case of the archetype scale, the scales are used separately for long-range shooting training. When the 5.56mm bullet- And there is an inconvenience in using it because the scales are removed and used.

1 to 10, the aiming apparatus 100 of the grenade launcher 10 according to an embodiment of the present invention includes a body 110, a target distance measuring unit 120, a controller 130, 140 may include at least one of an angle adjusting unit 150, a leveling unit 160, a data display unit 170, a dot site desorbing unit 180, and a power source unit 190.

The body portion 110 may be a body for components other than the dot site 140 and may have a coupling portion 110a at a side portion thereof to be detachably coupled to the grenade launcher 10. The fastening part 110a is connected to the body part 110 through a rotary shaft 150a and may have a substantially U-shape. The rotating shaft 150a is connected to the angle adjusting unit 150 so that the body 110 can be rotated.

The target distance measuring unit 120 is installed to face the front of the body 110, and the distance between the target and the grenade launcher 10 can be measured using a laser distance measuring method. The target distance measuring unit 120 measures a distance by detecting a reflected laser beam after emitting a laser beam toward a target. The target distance measuring unit 120 measures a distance between a transmitter generating laser and a laser reflected back from the target And a counter for counting time, etc. [0035] The light emitting diode (LED) The distance measurement may be performed in such a manner that the laser beam having the directivity is made to coincide with the collimation line of the target distance measuring unit 120 and then the distance is calculated by measuring the time when the laser beam is reflected from the target.

The control unit 130 may calculate the trajectory correction angle of the grenade launcher according to the distance measured through the target distance measuring unit. In addition, when the adjusting device 100 is set to the automatic collimating mode, the controller 130 can automatically control the driving of the angle adjusting unit 150 using the ballistic correction angle data. The control unit 130 may include a power switch 131, an ADC (Analog Digital Converter) 132, a ballistic correction angle calculation unit 133, a motor control unit 134, a CPU 135, and the like.

The power switch 131 is connected to the power source unit 190 and can control power supply from the power source unit 190 to the control unit 130 according to the switching operation.

The ADC (Analog Digital Converter) 132 converts an analog signal containing information on a target distance measured through the target distance measuring unit 120 into a digital signal and transmits the digital signal to a CPU (Central Processing Unit) 135 have.

The trajectory correction angle calculator 133 receives the target distance data through the CPU 135 and calculates the trajectory correction angle (or elevation angle) of the grenade launcher 10 based on the received data, And can transmit the respective data to the motor control unit 134.

The motor control unit 134 controls the amount of rotation of the driving motor unit 151 provided in the angle adjusting unit 150 based on the ballistic correction angle data received from the ballistic correction angle calculating unit 133. [

The CPU 135 can perform overall control and processing of an ADC (Analog Digital Converter) 132, a ballistic correction angle calculation unit 133, a motor control unit 134, and the like.

The dot site 140 may be installed on the upper portion of the body 110 and may rotate in a vertical direction within a predetermined angular range centered on a rotation axis formed at one end.

The dot site 140 is in the form of an optical sight and is called a holographic sight, a reflector sight, and a reflex sight, and is called a red dot sight or a red dot Red Dot).

In order to aim a target with a conventional mechanical sphygmomanometer, there is a need for a 'line-of-sight alignment' that places the eyes, scale, and clamps in a straight line. It is also very important to ensure visibility in a melee situation. The mechanical sight such as a needle eye is very narrow in view.

However, in the dot site 140, a dot is indicated by a dot at a position where the bullet meets through the lens. Since the impact point only points where the bullet is hit, unlike a mechanical sight, alignment of the sight line is easy, which can dramatically shorten the alignment time.

The dot site 140 is located at the center of the front reflecting lens in the light source inside the dot site, and uses a principle in which the parallax that always indicates only one point is eliminated, irrespective of the position viewed by the shooter. As a result, no matter what direction the shooter sees the site, the image of the dot on the site can only indicate an unconditional point. The dot site 140 is installed so as to maintain a parallel state with the target distance measuring unit 120 at all times.

The angular adjustment unit 150 may adjust the angle of the correction of the dot site 140 by adjusting the rotation angle of the body 110 according to the ballistic correction angle calculated through the controller 130. For this purpose, the angle adjusting unit 150 may include a rotating shaft 150a, a driving motor unit 151, a worm and worm gear unit 152, a trigger detecting unit 153, and a manual operating unit 154.

The driving motor unit 151 receives the ballistics correction angle data from the control unit 130, and can drive and rotate according to the received ballistics correction angle data. Here, the ballistic correction angle data may mean data on the motor rotation amount about how much the dot site 140 is rotated according to the distance from the grenade launcher 10 to the target. For example, the trajectory correction angle data is set so that the driving motor unit 151 is driven with a small amount of rotation as the distance from the grenade launcher 10 to the target is short, or the distance from the grenade launcher 10 to the target is long The recorded drive motor section 151 can be calculated to drive at a large amount of rotation.

The driving motor unit 151 may include a servo motor or a step motor. However, the driving motor unit 151 is not limited to such a motor, but may be a small motor capable of adjusting a fine rotation angle.

When the worm gear and the worm gear portion 152 transmit rotational force to a worm gear having a screw-shaped worm connected to the driving shaft of the driving motor portion 151 and connected at a right angle, the differential gear in the center of the worm gear moves up and down, So that the dot site 140 is rotated at a predetermined angle by rotating the body 110 around the center 150a.

Hereinafter, the manner of operation of the aiming apparatus 100 and the method of rotating the dot site 140 will be described with reference to the accompanying drawings.

5, when the shooter touches the target through the dot site 140 and presses the tact switch 121, the distance to the target is calculated through the target distance measuring unit 120 , And calculates the degree of rotation of the dot site 150 by the angle adjusting unit 150 based on the calculated angle. That is, the trajectory correction angle O of the grenade launcher 10 can be calculated according to the distance from the target.

6, the angle adjusting unit 150 rotates the body 110 at a predetermined angle O in accordance with the calculated ballistic correction angle O, When the target and the shooter are at a horizontal position, the turntable must be triggered with a parabolic curve at a predetermined elevation angle, so that the dot site 140 is rotated in the downward direction The trajectory correction angle?

In this way, when the dot site 140 is rotated by the trajectory correction angle (-O), the shooter positions the target through the dot site 140. In this process, the muzzle of the grenade launcher 10 is again subjected to the trajectory correction And can be aimed up by the angle (O).

The trajectory correction angle O can be corrected little by little at the previous trajectory correction angle O according to the distance from the target each time shooting is performed.

Alternatively, whenever the shooting is performed using the trigger detecting unit 153, the dot site 140 may be returned to the origin to be aimed, which may be set according to the driving mode of the dot site 140 of the shooting person.

The trigger detecting unit 153 may be installed in the body 110 to sense the triggering of the grenade launcher 10 by the vibration and output the triggering signal to the controller 130 when the trigger is detected. A variety of vibration detection sensors can be applied to the trigger detection unit 153 as a means for detecting the degree of vibration caused by the triggering of the grenade launcher 10.

At this time, the control unit 130 may output the origin return control signal to the drive motor unit 151 when receiving the trigger detection signal from the trigger detection unit 153. The origin return control signal is a control signal for returning the body 110 or the dot site 140 to the origin and initializes the position of the body 110 and returns to the origin parallel to the grenade launcher 10 .

The manual operation unit 154, the level meter 160, and the data display unit 170 may be used when the manual motoring unit 151 is not used.

The leveling unit 160 is installed in the body 110 and can measure the horizontal angle of the grenade launcher 10 and transmit it to the controller 130. Although this leveling system 160 preferably includes an electronic leveling system, an analog leveling system is additionally applicable.

The data display unit 170 can receive and display the horizontal angle data measured through the level system 160 and the target distance data measured through the target distance measurement unit 120 from the controller 130. [ In this way, the data display unit 170 may be a display device for displaying the information about the distance between the horizontal angle and the target so that the shooter can directly confirm the information.

The manual operation unit 154 can manually manipulate the worm and worm gear unit 152 according to the target distance data and the horizontal angle data displayed through the data display unit 170 to manually adjust the rotation angle of the dot site 140 . For this purpose, marking means for checking the rotation angle of the dot site 140 may be provided on the surface of the body 110.

The dot site desorption unit 180 is a means for detachably connecting the dot site 140 to the body 110 and may be formed by various methods such as threaded connection and interference fit, ) Can be detachably coupled. The dot site 140 separated from the body 110 through the dot site desorption unit 180 may be coupled to another fire source and used as an optical sight of the fire source.

The power source unit 190 may include a disposable battery or a secondary battery as a means for supplying power to the target distance measuring unit 120 and the controller 130. When the power source unit 190 uses a secondary battery, a connector for charging the battery may be provided. The power supply unit 190 may supply power to the target distance measuring unit 120 and the control unit 130 according to the switching operation of the tact switch 121.

According to the present embodiment, by using the dot site, it is possible to shorten the step of aligning the line of sight and aim and fire the target immediately.

In addition, since the dot site can be fired in both eyes (with two eyes open), the peripheral vision is wider than the conventional mechanical site, and the shooter using the dot site can understand the surrounding environment and situation more quickly and easily .

In addition, it can measure the distance with the laser without the hassle when aiming fire, and it can be automatically aimed at the corrected angle, so that it can cope with immediate shooting with simple operability.

In addition, when firing from a controlled distance angle due to the grafted technology, it is possible to shoot at a position close to the shot at a short distance, and shoot at a position where the shot falls when shooting at a long distance.

As described above, the present invention is not limited to the above-described embodiment, but may be applied to a gyro launcher according to the present invention, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
