Description

The utility model relates to optical-electronic instrumentation, in particular to small-sized laser light sources, and can be used to fine-tune any sights of small arms during the “cold” shooting phase and to train bench shooters without the use of ammunition.

Known laser cartridge for cold shooting of small arms according to the patent of the Russian Federation No. 147939, 2013, patent holder CJSC "Kantegir"), comprising a cylindrical body with a cylindrical laser module located in it, containing a lens and a laser diode; a laser diode driver electrically connected to the laser module by means of a spring; a battery isolated from the cartridge case; back cover with power-on device; radial threaded holes made in a cylindrical body in the region of the laser module; adjusting screws screwed into the threaded holes, and the power-on device includes a sleeve rigidly fixed in the center of the back cover and made of insulating material, inside of which there is a plunger in contact with the element. The disadvantages of the known solutions are inconvenient adjustment of the laser position and the inability to align. Laser sliding movement allows only focusing of the laser beam. The lens can stand crooked, and the laser will give a deviation along the axis of the laser beam, while the alignment is not adjustable. When fired, the plunger can break the battery. In addition, the cartridge cannot be used for training firing. The use of live ammunition for training bench shooters leads to increased wear of weapons, uneconomical consumption of ammunition and does not ensure the safety of training.

The closest, taken as a prototype, is a laser training cartridge (RF patent No. 2221983, 2001, patent holder Bystray A.P.) containing a cylindrical body equipped with a laser module that simulates a shot, and a laser module control unit, a battery compartment with batteries, adjusting screws and shock absorber. The shock absorber is made in the form of a sleeve with an element of mechanical action for issuing a signal to the control unit of the laser diode made of an elastic material, for example, rubber, batteries and springs. The control unit comprises a microphone, a first transistor amplifying the microphone signal, and a second transistor including a laser diode.

Analysis of the known solutions showed the following disadvantages. The presence of a rubber part in the design of the shock absorber, not as a gasket, but as a sensitive element for issuing a signal to the control unit, makes the cartridge work unstable with temperature and over time, because rubber properties vary greatly with temperature and time. In addition, the execution of the rubber element, which strikes the firing pin, will quickly lead to its failure from the strikes of the firing pin and ruin the trigger mechanism of the gun.

The switch 4 goes beyond the dimensions of the liner and has a spring-loaded operating principle. The force during compression of the switch spring will be directed radially to the axis of the cartridge, which will cause the cartridge to shift or skew in the barrel and, in turn, will lead to a mismatch between the laser axes and the axis of the gun barrel.

This design does not provide accurate adjustment of the direction of the laser beam relative to the longitudinal axis of the cartridge, since it does not provide mobility of the laser axis along two mutually perpendicular axes. Any impact on the adjusting screws will result in skewed construction and unpredictable beam behavior. The adjusting screws go beyond the dimensions and, in addition to the lack of an aesthetic component, do not have a locking mechanism, and when these screws are exposed, the plane of the laser beam is blocked, which makes it impossible to assess the correctness of the effect visually. In addition, in this design, the laser diode is triggered only after the striker is hit and glows briefly until the capacitor C2 is discharged. In this regard, the tuning process on the prism of the alignment of the beam of the laser diode in general becomes impossible, since it requires constant burning of the laser.

The analog control circuit has a significant current consumption, which makes the device work short, in addition, it has large dimensions. The absence of a current stabilization circuit makes the laser operation unstable, while the brightness varies greatly from the discharge of the batteries. Analog gain does not allow you to filter the noise signal correctly. Those. the cartridge will be sensitive to extraneous noise and will be triggered by any sound source that exceeds the configured threshold power.

The technical problem solved by the utility model is to increase the reliability and durability of the structure and to ensure the accuracy of adjusting the position of the axis of the laser beam relative to the body of the cartridge.

The technical problem posed is solved by the fact that in a known laser cartridge containing a cylindrical housing in which a laser module with a laser module control board is located, a battery compartment with batteries, adjusting screws and a shock absorber, in accordance with the stated solution, the laser module is mounted in a hinge, and the inner surface of the cylindrical body has a spherical support portion for contacting the outer surface of the hinge, the shock absorber is made in the form of a housing in which the holder and the threaded insert, while a shock spring is installed on the plunger rod, and a conical spring contact is installed in the threaded insert for transmitting voltage from the batteries through the cylindrical body of the cartridge to the spring contacts of the control board, while the control board includes a microcontroller, a battery, a power converter and an inertial measuring module comprising a shock sensor and a rotation sensor. The cylindrical body is equipped with radial threaded holes located in pairs in mutually perpendicular planes in the region of the laser module, in which the adjustment screws are installed, and the hinge is equipped with flats located in pairs in mutually perpendicular planes and intended for contact with the adjustment screws. The shock absorber body has an external threaded connection with the inner surface of the cylindrical cartridge case, and the threaded insert has an external threaded connection with the inner surface of the shock absorber and is a stop for the shock spring and the guide for the pusher rod. The battery compartment is equipped with a contact plate for transmitting voltage of negative polarity from the batteries to the spring contacts of the control board. The shock sensor of the control board is made using a built-in accelerometer, and the rotation sensor is made using a solid-state gyroscope.

The technical result that provides a solution to the problem is achieved through the use of a new set of features of the device. Installing the laser module in the hinge, which is located in the seat of the cylindrical body having an internal spherical section, allows you to deploy the hinge first in one plane, pressing it to the counter surface of the spherical section of the inner surface of the body, then in the perpendicular plane. In addition, the hinge is equipped with flats located in pairs in mutually perpendicular planes, which ensures reliable contact of the hinge surface with the adjusting screws, eliminating the rotation of the hinge around its own axis and gives a controlled distribution of force. This design enables precise adjustment of the position of the laser beam in two orthogonal planes.

The design of the shock absorber provides a linear movement of the pusher upon impact of the shotgun and the pusher returns to its original position after the end of the impact due to the fact that the shock spring is installed on the rod of the pusher, and the insert is a stop for the shock spring and the guide for the rod of the pusher. Such a combination of features ensures the reliability of the structure and the longevity of its work.

The control board, due to the presence of a solid-state accelerometer for detecting a hit on a shotgun and transmitting the fact of a hit to the microcontroller, and a solid-state gyroscope, provides two modes of operation: with the laser module turned on for 1 second after the hit of the striker or continuous laser light.

The laser cartridge contains a cylindrical housing 2, which houses the laser module 15 with a control board 11, a battery compartment 8 with batteries 7 and with a contact plate 9 and a shock absorber. The laser module 15 is installed in the hinge 14, and the inner surface of the cylindrical body 2 has a spherical support portion 23 for contacting the outer surface of the hinge 14. In the cartridge case 2, radial threaded holes are made in the region of the laser module 15, in which the adjusting screws 13 are located. The hinge 14 is provided with flats 22 located in pairs in mutually perpendicular planes and intended for contact with the adjusting screws 13. In the battery compartment 8 are the power elements I 7 and the contact plate 9. The batteries 7 serve to power the control board 11 and turn on the laser module 15. On the rear side of the cartridge housing 2 there is a shock absorber, the housing 1 of which has a threaded connection to the inner surface of the cylindrical cartridge housing 2. A pusher 3 and a threaded insert 5 are installed inside the shock absorber casing 1. A shock absorber spring 4 is installed on the rod 24 of the pusher 3. The insert 5 has an external threaded connection with the inner surface of the shock absorber casing 1 and is a stop for the shock spring 4 and the guide for the rod 24 of the pusher 3, providing the rectilinear movement of the pusher 3 upon impact of the shotgun and the return of the pusher 3 to its original position after the end of the impact. A conical spring contact 6 is installed in the threaded insert 5 to transmit positive polarity voltage from the batteries 7 through the insert 5, the shock absorber housing 1 and the cartridge case 2 to the positive spring contacts 12 of the control board 11, as well as to press the batteries 7 and ensure continuity of contact. The control board 11 is based on 4 spring contacts. To transmit a voltage of negative polarity from the batteries 7 to the spring negative contacts 10 of the control board 11, a contact plate 9 is used. when tightening the shock absorber housing 1, the control board is energized.

The control board 11 includes a microcontroller 20, a battery 16, a power converter 21, and an inertial measuring module 17 comprising a shock sensor 18 made using an integrated accelerometer and a rotation sensor 19 made using an integrated gyroscope.

The shock absorber 1 serves to mitigate the impact of the striker and prevent the failure of the trigger mechanism of the gun. And also for the correct operation of the mechanism of the shotgun removal gun cartridge. Case 2 imitates the cartridge case of a live cartridge and serves to place inside the parts of the laser cartridge, as well as to ensure alignment of the laser beam to the barrel of the gun. The pusher 3 simulates the capsule of a live cartridge and perceives the shock load from the striker of the gun. The depreciation spring 4 perceives the shock load from the striker of the gun transmitted by the pusher 3, softening the impact due to elastic deformation.

The control board 11 is used to determine the moment of the shot (pressing the trigger of the gun) or hit the striker of the gun and give a command to briefly turn on the laser module 15. As well as to determine the reciprocating rotation of the gun along the axis of the barrel and give a command to turn on the laser module 15 continuous burning mode or turning off the laser module 15 when the gun is turned again. Thus providing two modes of operation of the cartridge.

Adjusting screws 13 are used to adjust the alignment of the laser beam axis of the cartridge body 2 and the gun barrel by acting on the hinge 14, which has the ability to rotate the axis of the laser beam in two mutually perpendicular axes by means of rotation in the seat of the housing 2, made in the form of a spherical support section 23 for contacting the outer surface of the hinge 14.

Laser module 15 is used to illuminate a narrow beam of the visible (red) spectrum with a small scattering angle of the distant target when a shotgun is fired (by clicking on the trigger with an arrow) to visualize the point of impact in short-term and constant mode.

The control board 11 contains a microcontroller 20, which reads data from the inertial measuring module 17 and controls the power converter 21. The inertial measuring module 17 contains a shock sensor 18, made using an integrated accelerometer, and a rotation sensor 19. The battery 16 is designed to provide power inertial measuring module 17, microcontroller 20 and power converter 21. The power converter stabilizes the output voltage at a constant level, and on command e microcontroller supplies it to the laser module 15.

The control board operates as follows. The shock sensor 18, located in the inertial measuring module 17, detects the shock of the striker on the cartridge capsule and sends a signal to the microcontroller 20. When the signal is received from the sensor, the microcontroller supplies a control signal to the power converter 21, which stabilizes the voltage from the batteries 16 and supplies this voltage to the laser module 22 in accordance with the control program of the microcontroller 20. In the microcontroller 20 provides 2 lighting modes:

1. turning on the laser module for 1 second after striking;

2. continuous laser light.

The microcontroller 20 continuously reads data from the rotation sensor 19 and processes it for the presence of a specially defined motion profile (gesture): the cartridge rotates along the longitudinal axis by an angle of at least 60 ° and vice versa for 1 second. When a gesture is detected, the microcontroller 20 switches between the built-in glow profiles.

Short-term cartridge operation mode for the shooter training.

When you press the trigger of the gun, the striker of the gun strikes the follower 3, which transfers the kinetic energy of the striker to the depreciation spring 4, and moves along the guide insert 5, compressing the spring 4. After the end of the impact, the stored potential energy of the compressed spring 4 returns the pusher to its original state.

Part of the impact energy through the shock absorber 1 and the housing 2 is transmitted to the shock sensor 18 of the control board 11, which filters weak shocks and accelerations that are long in time, excluding the laser beam of the laser module 15 being ignited from the movements of the shooter during gun transfer and aiming.

The shock sensor 18 of the control board 11 extracts the signal from the impact of the striker gun and instructs the microcontroller 20 of the control board 11 to power the laser module 15 for a short period of time.

After receiving power, the laser module 15 ignites the beam and highlights a small spot in the visible spectrum on the target, which hit the shooter.

Continuous mode for adjusting optical sights.

When turning the gun with the hand along the axis of the barrel and returning to the initial state, the rotation sensor 19 of the control board 11 emits a signal, filtering out short-term movements when aiming and moving the weapon, and gives the command to the microcontroller 20 of the control board 11 to power the laser module 15 continuously (until the next command arrives) .

After receiving power, the laser module 15 ignites the beam and highlights a small spot of the visible spectrum with a spot on the target, in which the gun is pointed to adjust the crosshair of the optical sight on this spot (the operation of adjusting the optical sights).

During repeated manipulations with the rotation of the gun, the process repeats, and the rotation sensor 19 instructs the microcontroller of the control board 11 to remove power from the laser module, i.e. turn off the beam - turn off the continuous burning mode.

Alignment of the laser beam.

When the adjusting screw 13 is screwed in and the adjusting screw is loosened from the opposite side of the housing 2, the end of the screw of the adjusting screw 13 abuts against the flats 22 on the surface of the hinge 14, forcing it to rotate along an axis perpendicular to the plane of the axis of the screws and the longitudinal axis of the cartridge, turning the beam of the laser module 15. Opposite the displacement of the screws 13 will cause the beam to rotate along the same axis in the opposite direction.

Changing the position of the screws 13, perpendicular to the two previous ones, will cause the beam of the laser module 15 to rotate along an axis perpendicular to the axis of the housing 2 and the axis of the screws 13, which made the adjustment.

Thus, acting on 4 adjusting screws 13 (2 of which are orthogonal to the other two), the beam of laser module 15 is reduced to the axis of the body 2 and the axis of the gun.
