Description

Technical Field

[0001] This invention relates to the field of live-fire combat simulation training technology, and in particular to a live-fire combat laser simulation terminal based on dual-optical coaxial calibration. Background Technology

[0002] In live-fire combat simulation training, laser simulation terminals are typically used to replace live ammunition in shooting practice. These terminals are usually mounted on direct-fire weapons and determine hit damage by emitting invisible infrared laser projectiles. To ensure training effectiveness, the laser axis emitted by the simulation terminal must be highly parallel to the sight axis of the actual weapon to ensure the accuracy of the trajectory when soldiers use the original weapon's sights.

[0003] However, existing calibration schemes have several shortcomings. First, the calibration process relies excessively on bulky external auxiliary equipment such as infrared cameras and monitors, making operation cumbersome and requiring multiple personnel. Single-gun calibration can take 15-30 minutes. Furthermore, infrared lasers are susceptible to environmental radiation interference under strong sunlight, leading to significant difficulties in on-site calibration and failing to meet the rapid deployment requirements of large-scale training. Second, existing adjustment mechanisms lack effective anti-recoil locking and fine-tuning feedback structures. The severe vibrations generated by firearm firing can easily cause the calibrated adjustment axis to slip or shift. Simultaneously, due to the lack of accurate rotational damping and indexing feedback, operators struggle to precisely control the displacement during fine-tuning, easily leading to over-adjustment. Third, after calibration, the switching between visible calibration lasers and invisible strike lasers is often manually controlled. If this operation is forgotten, visible light can easily reveal one's position in combat situations. Fourth, conventional equipment lacks effective waterproof and dustproof sealing protection for its mounting base, light output window, and battery connection. In dusty and humid training environments in the field, sand and moisture can easily penetrate the interior, causing short circuits or contamination of optical lenses, thereby reducing the long-term operational stability and service life of the equipment.

[0012] As a preferred embodiment of the live-fire laser simulation terminal based on dual-optical coaxial calibration described in this invention, the yaw adjustment component includes a knurled knob, a transition plate, an indexing gear, and an adjustment shaft.

[0015] The inner end of the adjustment shaft is connected to the side of the dual-beam coaxial laser. Rotating the knurled knob can drive the dual-beam coaxial laser to deflect horizontally through the adjustment shaft.

[0016] As a preferred embodiment of the live-fire laser simulation terminal based on dual-optical coaxial calibration described in this invention, wherein: a spring is provided inside the adjustment shaft, one end of the spring abuts against the fixed-division insert tooth, and the other end abuts against the inner wall of the adjustment shaft to provide axial preload for the fixed-division insert tooth, so that the fixed-division insert tooth and the indexing tooth remain in a meshing state.

[0017] As a preferred embodiment of the live-fire laser simulation terminal based on dual-optical coaxial calibration described in this invention, the knurled knob is provided with a positioning pin, and the end of the adjustment shaft is provided with a positioning groove that cooperates with the positioning pin, for connecting the knurled knob and the adjustment shaft.

[0023] The beneficial effects of this invention are as follows: By integrating a pre-calibrated invisible infrared strike laser and a visible calibration laser inside the laser, this application eliminates the need for bulky external auxiliary equipment such as infrared cameras and displays, as is the case in traditional solutions, thus improving training efficiency. The adjustment mechanism adopts a structure with a graduated gear and a fixed-point insert gear, using a spring to provide axial preload to the fixed-point insert gear to achieve self-locking.

When switching to emission mode, the visible calibration laser is automatically disconnected to avoid location exposure and prevent accidental firing. Meanwhile, the terminal features sealed structures at the light-emitting panel, mounting base, and battery compartment cover, enhancing the device's dust and water resistance and ensuring operational reliability in complex field environments.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a live-fire laser simulation terminal based on dual-optical coaxial calibration.

[0040] Specifically, the transmitter main casing 101;

[0041] A dual-beam coaxial laser 105 is installed inside the main housing 101 of the transmitter. The dual-beam coaxial laser 105 can simultaneously emit an invisible strike laser and a visible calibration laser, and the invisible strike laser and the visible calibration laser are output in parallel along the same optical axis.

[0042] A calibration mechanism is provided between the transmitter main housing 101 and the dual-beam coaxial laser 105. The calibration mechanism includes a yaw adjustment component 201 and a pitch adjustment component 202, which are used to drive the dual-beam coaxial laser 105 to deflect in the horizontal and vertical directions, respectively, so as to adjust the laser emission angle.

[0043] And a mounting base plate 103 located at the bottom of the main housing 101 of the transmitter, the mounting base plate 103 having a clamp mounting port 1031 for connecting with the firearm.

[0044] First, the terminal device is attached to the corresponding slot on the firearm via the mounting plate 103 at the bottom of the transmitter main housing 101. Using the clamping mounting port 1031 on the mounting plate 103, and in conjunction with the firearm's clamping mechanism, the terminal is securely locked onto the firearm. Since the mounting plate 103 directly supports the entire device, this stable bottom connection structure ensures that the terminal will not slide relative to the firearm during rapid movement or firing, providing a stable physical basis for subsequent high-precision calibration.

[0045] After installation and securing, the operator turns on the power to the device. At this time, the dual-beam coaxial laser 105, located inside the transmitter's main housing 101, starts operating. The core of the dual-beam coaxial laser 105 is its ability to simultaneously emit two laser beams: one is an invisible strike laser used for combat simulation training, and the other is a visible calibration laser used for auxiliary calibration.

[0046] Because both laser beams have undergone precision tooling calibration at the factory, it ensures that the invisible and visible lasers are output in parallel along the same optical axis. Operators do not need bulky infrared cameras or displays on-site; they only need to calibrate for the visible light beam to simultaneously correct the parallelism of the invisible infrared laser beam's axis.

[0047] After the visible calibration laser is activated, the operator aims at the distant calibration target through the firearm's original sights and observes the landing point of the visible light spot on the target surface. If the light spot deviates from the target center of the sights, fine-tuning is required using the calibration mechanism located between the transmitter's main housing 101 and the dual-beam coaxial laser 105.

[0048] The calibration mechanism includes two non-interfering direction adjustment components. When the laser spot deviates to the left or right, the yaw adjustment component 201 is operated, which, when rotated, drives the dual-beam coaxial laser 105 to deflect horizontally. When the laser spot deviates upward or downward, the pitch adjustment component 202 is operated, driving the laser to deflect vertically. In practical use, the operator only needs to adjust the yaw adjustment component 201 and the pitch adjustment component 202 to flexibly bring the laser's impact point closer to the target center.

[0049] During actual adjustment, both the yaw adjustment component 201 and the pitch adjustment component 202 are equipped with indexing gears and spring-preloaded fixed-point insert gear mating structures. When the operator rotates the knob, the laser axis undergoes only a minute angular change of 0.05° for each indexing tooth, moving only about 2 centimeters over a distance of 50 meters. This design with extremely high damping and low angular displacement effectively avoids the problem of soldiers accidentally "over-adjusting" the knob due to hand tremors when operating it under stressful conditions.

[0050] When the visible light spot is perfectly aligned with the target center, the operator stops rotating. At this point, the preload of the internal spring 3042 firmly presses the indexing tooth 3041 into the corresponding indexing groove 3031, automatically locking it into a locked state. This ensures that the newly calibrated laser axis will not loosen or shift due to weapon vibration during subsequent live-fire simulations, guaranteeing a high hit rate in simulated engagements.

[0051] Example 2

[0052] Reference Figures 2-6 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0053] Specifically, the dual-beam coaxial laser 105 includes a laser housing, a first laser diode, a second laser diode, and a beam combiner disposed within the laser housing;

[0054] The first laser diode emits invisible infrared laser as the strike laser, and the second laser diode emits visible light as the calibration laser.

[0055] A beam combiner is located at the intersection of the optical axes of the first laser diode and the second laser diode to combine the two laser beams into a coaxial parallel beam output.

[0056] Inside the housing, there are two independent laser emission sources. The first laser diode is responsible for emitting invisible infrared laser, which serves as a simulated strike laser in live-fire combat. The second laser diode is responsible for emitting visible light, which serves as a calibration laser for operators to observe with their naked eyes.

[0057] The two laser beams are combined at their optical axis intersection by a beam combiner, ensuring that the invisible strike laser and the visible calibration laser are precisely parallel along the same optical axis. This physical structure with a built-in beam combiner guarantees the coaxial consistency of the two beams from the source of the optical path, eliminating the need for tedious secondary laser parallelism adjustments in the field and effectively avoiding the shortcomings of traditional solutions that rely on external infrared cameras for optical path alignment.

[0058] Preferably, the yaw adjustment component 201 includes a knurled knob 301, a transition plate 302, an indexing gear 303, and an adjustment shaft 304;

[0059] The knurled knob 301 is located on the outside of the transmitter main housing 101, and the adjusting shaft 304 passes through the side wall of the transmitter main housing 101 and is connected to the knurled knob 301.

[0060] When the operator observes through the aiming scope and finds that the visible spot deviates from the target center in the horizontal direction, the yaw adjustment component 201 needs to be activated for correction.

[0061] The yaw adjustment component 201 consists of a knurled knob 301, a transition plate 302, an indexing gear 303, and an adjustment shaft 304. The knurled knob 301 is located on the outside of the transmitter main housing 101 for easy manual gripping; the adjustment shaft 304 passes through the side wall of the main housing 101 and is physically connected to the knurled knob 301. During operation, the rotational power of the external knob is transmitted to the inside of the equipment through the adjustment shaft 304.

[0062] The indexing gear 303 is fixed to the inner wall of the transmitter main housing 101. The adjusting shaft 304 is provided with a fixed-division insertion tooth 3041, which meshes with the indexing tooth 3031 on the indexing gear 303.

[0063] The inner end of the adjustment shaft 304 is connected to the side of the dual-beam coaxial laser 105. Rotating the knurled knob 301 can drive the dual-beam coaxial laser 105 to deflect horizontally through the adjustment shaft 304.

[0064] After the power is transmitted to the interior, the indexing gear 303 is fixedly installed on the inner wall of the main housing 101 as a relatively static reference. On the adjusting shaft 304, a fixed-division inserting tooth 3041 that can rotate with the shaft is provided, which meshes with the indexing tooth 3031 on the indexing gear 303.

[0065] Since the inner end of the adjusting shaft 304 is connected to the side of the dual-beam coaxial laser 105, when the operator rotates the knurled knob 301, the adjusting shaft 304 rotates, and the adjusting shaft 304 then pushes and deflects the laser 105 fixed on it in the horizontal direction. Through the backlash fit between the indexing teeth 3041 and the indexing teeth 3031, each rotation is precisely physically limited, ensuring that the laser will not wobble wildly without any damping.

[0066] The adjusting shaft 304 is equipped with a spring 3042. One end of the spring 3042 abuts against the fixed-division insert tooth 3041, and the other end abuts against the inner wall of the adjusting shaft 304 to provide axial preload for the fixed-division insert tooth 3041, so that the fixed-division insert tooth 3041 and the indexing tooth 3031 are kept in meshing state.

[0067] The adjusting shaft 304 contains a specially installed spring 3042, one end of which is tightly pressed against the tail of the fixed-division insert 3041, while the other end rests against the inner wall of the adjusting shaft 304. The spring 3042 is always in a compressed state, thereby providing a continuous axial preload to the fixed-division insert 3041.

[0068] Under the action of this spring force, the fixed-point insert tooth 3041 is always pushed outward, forcing it to maintain a tight meshing state with the indexing tooth surface of the indexing tooth 3031.

[0069] After the operator adjusts the light spot to coincide with the target center, even if the operator stops and releases the knob, the thrust of the spring 3042 can firmly lock the tooth position, achieving self-locking without the need to tighten the locking nut; and the spring preload can effectively resist the strong recoil impact generated during live-fire shooting, ensuring that the adjustment shaft does not spin or deviate under severe vibration, and ensuring the long-term maintenance of calibration results.

[0070] The knurled knob 301 is provided with a positioning pin 3011, and the end of the adjusting shaft 304 is provided with a positioning groove that cooperates with the positioning pin 3011, for connecting the knurled knob 301 and the adjusting shaft 304.

[0071] To ensure that the angle is accurately transmitted to the adjusting shaft 304 every time the operator rotates the knurled knob 301, a positioning pin 3011 is specially provided on the knurled knob 301. At the same time, a positioning groove that precisely matches the positioning pin 3011 is provided at the end of the adjusting shaft 304.

[0072] When the two are assembled and connected, the locating pin 3011 fits precisely into the locating groove. This fixing method provides reliable anti-slip transmission, effectively eliminates the play caused by traditional cylindrical surface connections, and avoids operator misjudgment due to knob slippage.

[0073] The pitch adjustment component 202 has the same structure as the yaw adjustment component 201. The pitch adjustment component 202 is located on the top of the transmitter main housing 101 and is used to drive the dual-beam coaxial laser 105 to deflect vertically.

[0074] When the light spot deviates from the target center in the vertical direction, the operator needs to operate the pitch adjustment component 202. In this application, the pitch adjustment component 202 is located on the top of the transmitter main housing 101, and its internal structure is completely identical to that of the yaw adjustment component 201. Therefore, its vertical operation is the same as the horizontal yaw adjustment process, achieving precise fine-tuning in the vertical direction by driving the dual-beam coaxial laser 105 in the vertical direction.

[0075] In summary, during use, after the soldier installs the terminal onto the firearm, the dual-beam coaxial laser 105 is activated first. At this time, the light emitted by the first and second laser diodes forms coaxial visible and invisible light through a beam combiner. By observing the landing point of the visible light spot through the scope, if the light spot is off to the left or right, the knurled knob 301 of the yaw adjustment component 201 on the side of the main housing 101 is rotated to drive the adjustment shaft 304, thereby driving the laser 105 to make a horizontal fine adjustment. If the light spot is off to the top or bottom, the laser 105 is vertically aligned by rotating the pitch adjustment component 202, which has the same structure on the top.

[0076] During the adjustment of the knob, the spring 3042 inside the adjustment shaft 304 continuously pushes the indexing teeth 3041 to mesh with the indexing teeth 3031 on the indexing gear plate 303, providing a stable sense of positioning and self-locking force. When the red dot falls completely into the bullseye, the operator stops rotating. The spring preload ensures that there will be no slippage between the drive shafts and gear plates when subjected to recoil impact. The equipment then completes all calibrations and locks, and can then be switched to firing mode for simulated combat.

[0077] Example 3

[0078] Reference Figures 1-3 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0079] Specifically, the transmitter main housing 101 is also provided with a battery installation compartment 106, which contains a battery 1061. The outside of the battery installation compartment 106 is provided with an openable and closable installation cover 1062, and a sealing element is provided between the installation cover 1062 and the transmitter main housing 101.

[0080] Before the equipment is put into use, the operator opens the closable mounting cover 1062 on the outside of the transmitter main housing 101 and inserts the battery 1061 into the battery mounting compartment 106 located inside the transmitter main housing 101. After loading, the mounting cover 1062 is closed.

[0081] Because a seal is provided between the mounting cover 1062 and the transmitter main housing 101, the sealing structure can effectively prevent sand, rain or water vapor in the outdoor environment from entering the battery mounting compartment 106, thus preventing the battery 1061 from failing due to moisture or short circuit.

[0082] The transmitter main housing 101 is provided with a light-emitting window panel 102 on the light-emitting side, and a sealing rubber gasket 1021 is provided between the light-emitting window panel 102 and the transmitter main housing 101.

[0083] A sealing frame 1032 is provided between the mounting base plate 103 and the transmitter main housing 101.

[0084] When the dual-beam coaxial laser 105 inside the transmitter's main housing 101 is powered on and emits an invisible impact laser and a visible calibration laser, the optical path needs to extend from inside the device to the outside. At this time, the light-emitting window panel 102 on the light-emitting side of the transmitter's main housing 101 constitutes the output channel of the dual-beam coaxial laser 105.

[0085] Because a sealing rubber gasket 1021 is provided between the light-emitting window panel 102 and the transmitter main housing 101, this structure forms a tight waterproof and dustproof barrier for the laser emitting end after the equipment is assembled. In actual field training, the sealing rubber gasket 1021 can effectively prevent dust from adhering to the internal laser lens, and also avoid direct rainwater penetration that could cause moisture damage to the internal precision optical components, ensuring that the equipment emits clear light and produces undamaged images under various weather conditions.

[0086] A sealing frame 1032 is also provided between the mounting base plate 103 and the transmitter main housing 101. This sealing frame 1032 fills and seals the connection gap between the mounting base plate 103 and the main housing 101, cutting off the channel for external impurities and moisture to flow back into the main housing from the bottom joint of the equipment.

[0087] The transmitter's main housing 101 also houses a control circuit board 104, which is electrically connected to the dual-beam coaxial laser 105 and the battery 1061. The control circuit board 104 is equipped with a mode switching switch for switching between calibration mode and transmission mode.

[0088] The control circuit board 104 serves as the central connection point of the device, electrically connecting to the dual-beam coaxial laser 105 and the battery 1061 to ensure safe power delivery. The control circuit board 104 also features a mode switch. Operators can activate the circuit interlock function by simply toggling this switch. When switching to calibration mode, the circuit board 104 connects the visible light circuit and disconnects the strike laser circuit, allowing soldiers to aim and calibrate visually. Upon completion of calibration and switching back to firing mode, the circuit board 104 immediately disconnects the visible light circuit and connects the invisible strike laser circuit.

[0089] This interlocking logic based on circuit board 104 and mode switching switch eliminates the risk of simultaneous dual-light emission or mode confusion. At the same time, it allows soldiers to automatically conceal visible calibration light sources without additional operation when entering actual combat firing after completing calibration, thus preventing the exposure of their own position.

[0090] In summary, before field training, operators open the mounting cover 1062, place the battery 1061 into the battery mounting compartment 106, and lock it. The sealing components ensure the battery compartment is waterproof and dustproof, providing a stable power supply. After the equipment is powered on, the light-emitting window panel 102 on the light-emitting side of the transmitter's main housing 101 and the sealing rubber gasket 1021 jointly protect the optical output end, ensuring smooth laser transmission. At the same time, the sealing frame 1032 between the mounting base plate 103 and the main housing 101 isolates the bottom seam of the equipment, protecting the internal components from mud and water intrusion. When preparing to fire, the operator operates the mode switching switch on the control circuit board 104 to put the equipment into calibration mode, allowing soldiers to use visible lasers to complete aiming correction. After the aiming point coincides with the visible light spot, the mode switch is turned on again to enter firing mode, concealing the visible laser and activating the invisible strike laser, ready for live-fire simulation.

[0091] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
