Description

Technical Field

[0001] This invention relates to the field of light weapons simulation training and education equipment technology, specifically to a method and apparatus for constructing modular training equipment based on standard hardware components. Background Technology

[0002] Currently, with the modernization of military training, the development of public safety emergency response capabilities, and the deepening of national defense education, the demand for high-fidelity, low-cost, and safe and controllable simulation training equipment continues to grow. Traditional training methods mainly rely on real weapons or highly realistic simulated firearms, but in practical applications, they face a dilemma of being "legal but useless" and "useful but illegal." Some civilian training equipment is made of plastic, wood or low-density materials. Although it fully complies with laws and regulations, it is lightweight, has an unbalanced center of gravity, and poor handling. It cannot reproduce the operating experience of real weapons, and the training effect is greatly reduced, making it difficult to meet the training requirements of the military, police or professional. Some highly realistic simulated firearms are made of metal materials, have a real appearance and structure, and have a similar feel to real firearms. They have high training value, but due to factors such as appearance, size and material, they are easily identified as "simulated firearms". According to the "Standards for the Identification of Simulated Firearms" (Public Security Notice No. 8

[2008] ), they face bans on sale, seizure and even legal liability. They cannot be transported by express delivery, let alone circulated in the open.

[0003] This dilemma severely restricts the popularization and application of simulation training equipment. On the one hand, military and police units need highly realistic training tools to improve their combat capabilities; on the other hand, the civilian market and educational institutions find it difficult to obtain suitable products due to legal risks and cost barriers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method and apparatus for constructing modular training equipment based on standard hardware components. This solves the problem that military and police units need highly realistic training tools to improve their combat capabilities, while the civilian market and educational institutions struggle to obtain suitable products due to legal risks and cost barriers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular training equipment construction method based on standard hardware parts, comprising the following steps: S1. Select the profile lengths of the front, middle, and rear modules according to training requirements; S2. Use brackets, connecting plates, or bolts to connect the front module, middle module, and rear module at a straight line of 180° or at a 75° angle. S3. Insert the electronic simulation sight into the T-slot at the top of the middle module and tighten the side lock screws; S4. Install the trigger module and battery; S5. Add 1-3 counterweight modules to the front module according to the feel requirements. The counterweight modules are connected by threads. The profiles of the counterweight module, corner brackets, bolts, front module, middle module, and rear module are all general standard parts.

[0006] Through the above solutions—emphasizing structural abstraction, vibrant color schemes, and a separation of military and civilian versions—this product completely circumvents the certification requirements of the "Replica Gun Certification Standard," enabling legal circulation. Furthermore, it utilizes all commercially available common hardware components, reducing material costs. The modular design allows for individual component replacement, lowering maintenance costs, and it can be disassembled into a flat package, reducing its volume to 1 / 5 for easy transport. No complex processing is required, allowing for rapid assembly and significantly increasing production capacity. The metal structure provides a realistic feel, and by adjusting the profile length and module position, it can be quickly reconstructed to simulate various gun types, adapting to different training scenarios and offering strong scalability.

[0007] Preferably, the release structure of the trigger module is a gate stop.

[0008] Preferably, the release structure of the trigger module consists of a grip and a trigger lever.

[0009] Preferably, a slider is slidably connected in the profile groove of the rear module, the slider is fixedly connected to the end of the reset spring, and the slider is adjusted by bolts.

[0010] Preferably, the profile of the rear-end module is fitted with an adjustable cheek rest by bolts, the cheek rest slides within the profile groove of the rear-end module by bolt adjustment, and the tail of the profile of the rear-end module is fitted with a foldable L-shaped rear support plate by bolts.

[0011] A modular training apparatus based on standard hardware components, comprising a front module, a middle module, and a rear module; wherein: The front and rear modules are composed of single profiles; The middle section module is composed of two profiles stacked one on top of the other. The middle section module is equipped with a battery compartment and a circuit interface for installing electronic functional modules. The top of the middle section profile is equipped with a T-slot or guide rail structure for mounting an electronic simulation sight, laser emitter, or attitude sensor. The middle section module integrates a micro switch, and a pull handle is slidably connected inside the upper profile of the middle section module.

[0012] Preferably, it also includes an electronic system, which includes a laser emitting module, an IMU module, and a Bluetooth module. The laser emitting module is used to simulate the firing trajectory, the IMU module collects aiming sway data, and the Bluetooth module transmits data to a mobile phone / tablet APP in real time. The IMU consists of a three-axis accelerometer and a gyroscope.

[0013] Preferably, the profile of the rear module is detachably connected to a chin rest and an L-shaped rear support plate.

[0014] Preferably, a door stop is installed at the bottom of the middle section module, and the rebound end of the door stop can fit into the linkage lever.

[0015] Preferably, a limiting protrusion is fixedly connected to the lower outer wall of the pull handle, and a grip and trigger lever are installed at the bottom of the middle section module. The trigger lever can fit against the limiting protrusion. A slide rod is slidably connected inside the middle section module. One end of a return spring is fixedly connected to the outer wall of the slide rod, and a slider is fixedly connected to the other end of the return spring. The outer wall of the slider is slidably connected to the inside of the rear module profile, and an adjusting bolt is provided inside the slider.

[0016] This invention provides a method and apparatus for constructing modular training equipment based on standard hardware components. It offers the following advantages: 1. This invention completely avoids the risks associated with the "Replica Gun Certification Standard" through its abstract structural design (non-integrated gun shape) and separation of military and civilian versions. The military and police version maintains its combat realism by adding a grip and an adjustable spring, while the civilian version achieves legal circulation through modular reconfiguration. It meets the needs of multiple scenarios such as national defense popularization and counter-terrorism training, and combines low cost, high efficiency, and scalability, resolving the industry's dilemma of legality and practicality.

[0017] 2. This invention uses all commercially available standard hardware parts, eliminating the need for mold making and custom processing, significantly reducing the cost per unit compared to traditional simulation guns. The modular structure supports component-level replacement; partial damage does not require complete scrapping, reducing maintenance costs and extending service life. Using aluminum alloy, carbon steel, and other metal materials, coupled with an adjustable counterweight module, the overall weight deviates little from that of a real weapon, and the center of gravity distribution closely resembles actual equipment, enhancing the training immersion.

[0018] 3. This invention supports changing the length and connection angle of the profiles through a modular layout, allowing for rapid reconstruction into various forms such as rifles, submachine guns, and pistols to adapt to different training scenarios. It reserves standardized T-slots and electrical interfaces, supporting plug-and-play functionality for modules such as electronic simulation sights, laser emitters, and IMU sensors, and can be integrated with VR / AR systems to form an intelligent training closed loop.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a method for constructing modular training equipment based on standard hardware parts, including the following steps: S1. Select the profile lengths of the front module 2, middle module 1, and rear module 3 according to training requirements; S2. Use angle brackets, connecting plates 8 or bolts to connect the front module 2, middle module 1 and rear module 3 in a straight line of 180° or at a 75° angle. S3. Insert the electronic simulation sight into the top T-slot of the middle section module 1 and tighten the side lock screws; S4. Install trigger module 6 and battery; S5. Add 1-3 counterweight modules 7 to the front module 2 according to the feel requirements. The counterweight modules 7 are connected by threads. The profiles of counterweight module 7, corner brackets, bolts, front module 2, middle module 1, and rear module 3 are all general standard parts.

[0023] Specifically, the core of this solution lies in using commercially available industrial standard parts (such as 3030 European standard aluminum alloy profiles, M6 bolts, angle brackets, connecting plates 8, etc.) to achieve rapid assembly and reconstruction. This is achieved through the following design: First, it consists of three modules: the front section, the middle section, and the rear section. Their lengths can be flexibly cut according to the training objectives (for example, 500mm, 400mm, and 550mm for rifle configurations, and correspondingly shorter for submachine guns and pistols) to simulate the barrel, receiver, and stock sections. The sections are connected by L-shaped galvanized carbon steel angle brackets (30×30×3mm) or straight connecting plates 8 in conjunction with M6 hexagonal socket head cap screws. A rigid connection is established, supporting 180° straight or 75° angled layouts to adapt to different weapon grip angles and center of gravity distributions; the electronic simulation sight slides into the T-slot (10×15mm) at the top of the middle section module 1 via a bottom T-nut and is secured by a side locking screw for quick mounting; the trigger module 6 is installed at a designated position below the middle section, triggered by a microswitch, and has a built-in battery; the counterweight module 7 is a standard cast iron part (50×30×10mm, 100g / 200g optional), fixed to the front section via an M6 threaded hole at the bottom, and 1-3 modules can be installed as needed to precisely adjust the center of gravity. This application uses all general-purpose hardware parts that conform to national standards (such as profiles in GB / T6892-2015), which reduces costs, facilitates quick assembly, and reduces the packaging volume after disassembly, allowing it to be laid flat in a courier box; the overall weight and center of gravity are highly consistent, effectively enhancing the training immersion; at the same time, the interchangeability of standard parts reduces maintenance costs, taking into account the needs of multiple scenarios such as military and police tactical training and civilian science popularization, and solving the problems of traditional equipment having single function, poor quality, and high manufacturing cost.

[0024] Example 1 The release structure of trigger module 6 is a gate resistor 611.

[0025] Specifically, for civilian training equipment, the release structure of trigger module 6 uses a commercially available industrial spring-loaded door catch as the door stop 611, which is compatible with the 3030 profile slot width and is fixed to the lower profile of the middle module 1 by two M4 bolts spaced 30mm apart. The door stop 611 incorporates a high-precision microswitch and a stainless steel return spring 624. When the user pulls the trigger, the linkage lever 612 compresses the door stop 611, triggering the microswitch to generate a discharge signal. By using a standard door catch instead of a traditional custom spring structure, not only are costs reduced, but high reliability is also achieved. Furthermore, as an independent standard module, it can be directly purchased or used for batch replacement, and maintenance can be completed by simply removing two fixing bolts, improving maintenance efficiency.

[0026] Example 2 The release structure of the trigger module 6 consists of a grip 621 and a trigger lever 622.

[0027] Specifically, for military and police tactical training, this application also provides a more precise simulation method. First, a grip 621 is added. The grip 621 is made of engineering plastic injection molding or 6061 aluminum alloy milling. The surface is treated with frosting or anodizing to form an anti-slip texture to prevent slippage. The internal space is reserved for battery compartment to accommodate batteries and is connected to the middle module 1 by M6 bolts. The trigger lever 622 is made of stainless steel or carbon steel with chrome plating. The overall modular design allows for the replacement of grips 621 of different sizes, which is highly expandable and can be accurately matched with real firearms for military and police, helping trainees to accurately grasp the firing timing and enhance the realism of training.

[0028] A slider 625 is slidably connected in the profile groove of the rear module 3. The slider 625 is fixedly connected to the end of the return spring 624, and the slider 625 is adjusted by bolts.

[0029] Specifically, to further enhance the simulation effect of military and police tactical training, the slider 625 and the profile groove of the rear module 3 are designed to ensure smooth and unobstructed sliding. One end of the return spring 624 is welded and fixed to the end face of the slider 625, while the other end abuts against the limiting block inside the rear module 3. Its pre-compression is adjustable. By screwing the adjusting bolt into the threaded hole of the slider 625 and tightening it against the inner wall of the profile, the initial position of the slider 625 can be changed, thereby adjusting the preload of the return spring 624 and achieving personalized trigger force adjustment to adapt to different training scenarios. Simulating the real bolt return action, it features uniform sliding resistance, fast return response, and strong operational realism, effectively solving the limitation of the traditional non-adjustable return structure.

[0030] An adjustable cheek rest 4 is bolted onto the profile of the rear module 3. The cheek rest 4 slides within the profile groove of the rear module 3 via bolt adjustment. A foldable L-shaped rear support plate 5 is bolted onto the tail of the profile of the rear module 3.

[0031] Specifically, the rear module 3 is bolted to an adjustable chin rest 4 and a foldable L-shaped rear support plate 5. The chin rest uses a plastic base plate covered with a silicone pad for enhanced comfort. It is locked in place by M6 bolts with pre-tightening torque, allowing for sliding adjustment to accommodate different users and enhance aiming stability. The L-shaped rear support plate 5 is an aluminum alloy bent piece, typically a 90-degree folding structure used in furniture. Connected by stainless steel hinges, it can rotate 90° around its axis to fold parallel to the profile, reducing its volume when folded for easy storage and transportation. When unfolded, it maintains a 90° angle with the profile, providing stable shoulder support to enhance training immersion.

[0032] Please see the appendix Figure 1 -Appendix Figure 6 A modular training apparatus based on standard hardware components includes a front module 2, a middle module 1, and a rear module 3; wherein: The front module 2 and the rear module 3 are composed of single profiles; The middle section module 1 is composed of two profiles stacked one on top of the other. The middle section module 1 is equipped with a battery compartment and a circuit interface for installing electronic functional modules. The top of the middle section profile is equipped with a T-slot or guide rail structure for mounting an electronic simulation sight, laser emitter or attitude sensor. The middle section module 1 integrates a micro switch, and a pull handle 601 is slidably connected inside the upper profile of the middle section module 1.

[0033] Specifically, in one embodiment, the device consists of a front module 2, a middle module 1, and a rear module 3. Each module uses 6063-T5 aluminum alloy 3030 European standard profiles, with a sandblasted and anodized surface. Military and police modules can be painted with camouflage, while civilian modules can be painted in different colors for easy assembly. The front module is 300–500mm long and has M6 threaded holes for adding weights. The rear module is 300–600mm long and can be cut as needed. The overall design achieves high rigidity while being lightweight, with a weight range of 1.2–5.8kg, deviating from the weight of a real weapon by ≤10%, effectively improving the lack of texture in traditional plastic models. The middle module 1 is constructed by stacking two profiles vertically, with a spacing of 180mm, and is fixed with four sets of L-shaped brackets and M6 bolts, forming a stable double-layer guide rail frame structure. The top of the middle section features a T-slot and Picatinny rail, compatible with European standard nuts and mainstream electronic simulation sights, laser emitters, and other accessories, enabling plug-and-play expansion capabilities. The 601 charging handle accurately simulates the reciprocating motion of a bolt; its sliding trajectory corresponds to the built-in microswitch, with a trigger travel of 2–3 mm, ensuring accurate signal triggering.

[0034] It also includes an electronic system, which includes a laser emission module, an IMU module, and a Bluetooth module. The laser emission module is used to simulate the firing trajectory, the IMU module collects aiming sway data, and the Bluetooth module transmits data to a mobile phone / tablet APP in real time. The IMU consists of a three-axis accelerometer and a gyroscope.

[0035] Specifically, this electronic training system integrates laser emission, IMU sensing, and Bluetooth communication modules into a single unit, which is integrated into the PCB and fixed to the middle section structure via T-slots. The laser emission module uses red LEDs to accurately simulate firearm ballistics. The IMU module synchronously acquires three-axis acceleration and angular velocity data based on a chip, and works with the main control board to achieve real-time data processing. The Bluetooth module incorporates low-power design and power protection mechanisms to ensure stable system operation. While ensuring safety, this system effectively improves the scientific rigor and effectiveness of shooting training, making it suitable for military and police tactical exercises as well as civilian science popularization scenarios.

[0036] The rear module 3 has a detachable chin rest 4 and an L-shaped rear support plate 5.

[0037] Both the chin rest and the rear support plate adopt a detachable connection structure with quick-release bolts and slots. The quick-release bolts cooperate with the aluminum alloy slots to fit into the T-slots of the rear profile; tightening the bolts during installation secures the plate. The chin rest is secured with nuts and has a sliding plate at its bottom that adapts to the profile slot. The L-shaped rear support plate 5 is installed at the rear of the profile and can be folded from 0 to 90 degrees using hinge bolts. After unfolding, it is locked by a knob.

[0038] A gate stop 611 is installed at the bottom of the middle section module 1. The rebound end of the gate stop 611 can fit into the linkage lever 612.

[0039] Specifically, the door stop 611 is fixed to the lower middle section profile by two L-shaped brackets and bolts, with a positioning hole spacing of 50mm; the door stop 611 is reset by an internal spring. One end of the lever is in contact with the return end of the door stop 611, and the other end is kept 1-2mm away from the trigger end of the trigger module 6 to achieve synchronous triggering with the trigger module 6. When the charging handle 601 is pulled back to its full position, it will compress the lever to trigger the door stop 611 to return, simulating the impact sensation when the bolt returns to its forward position.

[0040] The lower outer wall of the pull handle 601 is fixedly connected to 626. The bottom of the middle section module 1 is equipped with a grip 621 and a trigger lever 622. The trigger lever 622 can fit against 626. The middle section module 11 is internally slidably connected to a slide rod 623. The outer wall of the slide rod 623 is fixedly connected to one end of a return spring 624. The other end of the return spring 624 is fixedly connected to a slider 625. The outer wall of the slider 625 is slidably connected to the inside of the rear section module 3 profile. An adjusting bolt is provided inside the slider 625.

[0041] Specifically, a limit protrusion 626 is fixed to the lower outer wall of the trigger lever 601 by an M3 bolt. The bottom has a 3mm radius arc-shaped groove that fits into the spherical structure (2mm radius) at the top of the trigger lever 622. When the trigger is pulled, the trigger lever 622 rotates counterclockwise, pressing the limit protrusion 626 and causing the trigger lever 601 to move forward. Simultaneously, the slider 625 compresses the return spring 624, which is sleeved outside the slide rod 623. The slide rod is made of stainless steel with a chrome-plated surface and engages with the copper guide sleeve inside the middle module 1, with a sliding resistance ≤5N. After releasing the trigger, the return spring pushes the slider 625 back to its original position, causing the trigger lever 601 to retract, completing one firing cycle. An adjusting bolt is located inside the slider 625. Rotating the bolt slides the slider 625, adjusting its position and thus changing the spring pre-compression, allowing for adjustable rebound speed within a specified range. This linkage structure accurately simulates the bolt-trigger linkage mechanism of a real firearm, with smooth sliding and sensitive triggering, enhancing the immersive experience of operation; the adjustment function can adapt to the different force preferences of different users, enhancing versatility.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
