Abstract

This invention discloses a small arms shooting finger technique training simulator and training method, including a simulated trigger module, a resistance adjustment module, a speed detection module, a control module, and an audio-visual feedback module. The resistance adjustment module can precisely adjust and maintain a specific stable resistance to adapt to the resistance characteristics of different small arms triggers. The speed detection module collects the speed signal of the finger pressing the simulated trigger in real time and transmits it to the control module. The control module judges whether the pressing speed change is within a preset small range: if the speed is stable within the range, the audio-visual feedback module lights up green; if the pressing is too fast and unstable, it lights up red; if the pressing is too slow and unstable, it lights up yellow. This invention constructs a realistic trigger feel through adjustable and stable resistance, combined with graded audio-visual feedback to guide the finger muscles to exert precise force, efficiently trains the finger muscle control ability, and quickly forms standardized shooting pressing muscle memory. It has a simple structure, strong practicality, and is suitable for basic finger technique training for various small arms shooting.

Description

Technical Field

[0001] This invention relates to the field of light weapons training equipment technology, specifically to a light weapons shooting finger training simulator and training method. Background Technology

[0002] The accuracy of small arms shooting is closely related to the stability of the finger pressing the trigger. A high-quality trigger pressing action must meet the requirements of "uniform force, stable speed, and controllable stroke," and the formation of this action relies on the finger muscle memory developed through long-term training. Existing small arms shooting finger technique training mostly uses live-fire blank cartridge training or simple simulated trigger training, which has many limitations: On the one hand, live-fire training is costly and risky, and it is difficult to provide precise quantitative feedback on the finger pressing speed and force. Trainees can only rely on verbal guidance from the instructor to adjust their movements, and cannot perceive deviations in their pressing state in real time, resulting in low efficiency in the formation of muscle memory. On the other hand, existing simple simulated triggers mostly lack resistance adjustment functions, or have low resistance adjustment accuracy and poor stability, and cannot adapt to the trigger resistance characteristics of different small arms models. The simulation scenario is not realistic enough, and there is a lack of graded feedback mechanism for pressing speed, which cannot effectively guide trainees to correct problems such as "pressing too fast, too slow, or large speed fluctuations," making it difficult to achieve standardized training results.

[0003] Therefore, there is an urgent need for training equipment that can precisely adjust and maintain stable resistance, monitor pressing speed in real time, and provide graded feedback. This would address the shortcomings of existing training methods, help trainees efficiently build finger muscle memory, and improve the standardization and stability of shooting finger techniques. Summary of the Invention

[0004] To address the problems of existing light weapons shooting finger technique training equipment lacking precise, adjustable, and stable resistance and real-time speed-graded feedback, resulting in slow muscle memory formation and poor training effects, this invention provides a light weapons shooting finger technique training simulator and training method. By constructing a realistic trigger resistance environment and a clear audio-visual feedback mechanism, it guides trainees to precisely control finger force and quickly form standardized pressing muscle memory.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A light weapons shooting finger training simulator includes a simulated trigger module, a resistance adjustment module, a speed detection module, a control module, and an audio-visual feedback module. These modules work together to achieve adjustable resistance, speed monitoring, and tiered feedback functions. The specific structure is as follows: Simulated trigger module: It adopts the same material and shape design as the real light weapon trigger, has an arc-shaped contact surface that is adapted to the finger pressing, and has an internal pressing stroke limit structure to ensure that the pressing stroke is consistent with the corresponding light weapon trigger stroke, simulating the real grip and pressing feel, and avoiding the difficulty for trainees to switch to real gun operation after adapting to the simulation equipment.

[0006] The resistance adjustment module consists of an adjustment knob, an elastic element (preferably a disc spring assembly with high strength and stability), a resistance sensor, and a transmission rod. The adjustment knob can be manually rotated or electrically driven to adjust the preload of the elastic element, thereby changing the pressing resistance of the simulated trigger. The adjustment range covers 0.5-5N (compatible with the trigger resistance of common light weapons such as pistols, rifles, and submachine guns), with adjustment steps accurate to 0.1N. The resistance sensor collects the resistance value in real time during the pressing process and transmits the signal to the control module. The control module adjusts the preload of the elastic element through closed-loop control to ensure that the resistance stability error does not exceed ±5%, avoiding resistance fluctuations from affecting the training effect.

[0007] Speed ​​detection module: This module employs a combination of a high-precision displacement sensor (preferably a laser displacement sensor with a measurement accuracy of 0.01mm) and a high-precision timer. The displacement sensor is mounted at the bottom of the simulated trigger module, acquiring real-time displacement changes during trigger pressing. The timer synchronously records the time corresponding to each displacement segment, transmitting both displacement and time signals to the control module. The control module calculates the instantaneous pressing speed and speed change rate based on the displacement-time curve. The speed change rate serves as the core indicator for determining the stability of the pressing action, ensuring accurate identification of pressing speed fluctuations.

[0008] Control Module: A microcontroller (preferably STM32 series, with high-efficiency computing and multi-module adaptability) is used as the core control unit, with built-in storage, signal processing, and I / O interfaces. The storage unit presets at least three sets of speed reference ranges and stability thresholds (e.g., precision shooting mode reference speed 0.2-0.5cm / s, stability threshold ≤10%; rapid shooting mode reference speed 0.5-1.0cm / s, stability threshold ≤15%). Trainees can switch modes via external buttons or manually adjust the reference range and thresholds. The signal processing unit filters, amplifies, and calculates the signal transmitted from the speed detection module, compares it with preset parameters, and outputs control commands to the audio-visual feedback module.

[0009] The audio-visual feedback module includes three high-brightness LED indicators (green, red, and yellow) and a buzzer. The indicators are prominently displayed on the simulator's casing for easy observation by the trainee. When the control module outputs different commands, the corresponding indicator lights up and the buzzer sounds: a green light indicates stable and satisfactory pressing (no buzzer), guiding the trainee to maintain the current action; a red light accompanied by a high-frequency buzzer (2kHz) warns of pressing too quickly and unstablely, requiring slowing down and controlling the evenness of force; a yellow light accompanied by a mid-frequency buzzer (1kHz) indicates pressing too slowly and unstablely, requiring moderately increasing the speed while maintaining stability.

[0010] In addition, the simulator also includes a shell and a mounting bracket. The shell is made of high-strength ABS material with a non-slip grip surface and integrates mounting slots for each module to ensure a compact structure. The mounting bracket has an adjustable design, which can fix the simulator to a desktop, a gun training rack, or a simulated gun body to simulate the grip posture during real shooting and enhance the realism of the training scenario.

[0011] The light weapons shooting finger technique training method based on the above simulator includes the following steps: S1: Pre-training preparation. Determine the appropriate trigger resistance parameters based on the training objective (e.g., pistol precision shooting training). Set the resistance value using the adjustment knob on the resistance adjustment module. The control module activates the resistance monitoring closed loop. The resistance sensor provides real-time feedback on the resistance value. The control module automatically fine-tunes the preload of the elastic element to maintain the resistance stable at the set value. Simultaneously, select the corresponding speed reference range and stability threshold according to the training stage. In the initial training, a wider reference range (e.g., 0.1-0.6 cm / s) and a higher stability threshold (≤20%) can be set to reduce the training difficulty. In the later stages, gradually narrow the range and increase the threshold to achieve step-by-step progressive training.

[0012] S2: The trainee holds the simulator shell or fixes the simulator to the simulated gun body through the fixed bracket, holds it in the same posture as real shooting, places the index finger on the arc contact surface of the simulated trigger module, keeps the arm and wrist stable, and is ready to press.

[0013] S3: The trainee slowly presses down the simulated trigger according to the shooting specifications, keeping the force applied by the finger even during the pressing process. The displacement sensor of the speed detection module collects the trigger displacement signal in real time, and the timer records the time data synchronously. A set of data is transmitted to the control module every 10ms.

[0014] S4: The control module processes the received displacement and time data, calculates the instantaneous pressing speed for each time period, and simultaneously calculates the speed change rate between adjacent time periods. It compares the results with the preset speed reference range and stability threshold, makes a three-level judgment, and controls the action of the audio-visual feedback module. a) When the instantaneous speed is always within the preset benchmark range and the rate of change of speed throughout the process is ≤ the stability threshold, it is judged that the pressing is stable and qualified. The control module outputs a command to make the green light light up and there is no beeping sound. The trainee can continue to maintain the pressing rhythm and repeat the training to strengthen muscle memory. b) When the instantaneous speed exceeds the upper limit of the baseline range and the rate of change of speed is greater than the stability threshold, it is determined that the pressing is too fast and unstable. The control module outputs a command to make the red light light up, and at the same time the buzzer emits a high-frequency warning sound. After receiving the warning, the trainee needs to immediately adjust the force of the fingers, slow down the pressing speed, and control the uniformity of the force to reduce speed fluctuations. c) When the instantaneous speed is lower than the lower limit of the benchmark range and the rate of change of speed is greater than the stability threshold, it is determined that the pressing is too slow and unstable. The control module outputs a command to make the yellow light turn on and the buzzer emits a medium-frequency prompt tone. The trainee needs to appropriately increase the pressing speed while maintaining stable force and avoiding sudden changes in speed.

[0015] S5: The trainee continuously adjusts the finger pressing action based on the audio-visual feedback, repeating steps S3-S4. After each pressing, the simulated trigger is reset (through the automatic reset function of the elastic element), and the pressing training is performed again. The duration of a single training session can be set to 10-20 minutes. The training is repeated daily to gradually form the muscle memory of trigger pressing with "even force and stable speed". After the training is completed, the training data (such as the number of qualified pressings and the number of red / yellow light triggers) can be viewed through the control module to evaluate the training effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Precise and stable resistance environment: The resistance adjustment module enables precise resistance adjustment within the range of 0.5-5N. Combined with closed-loop control, it maintains stable resistance and can perfectly adapt to the trigger resistance characteristics of different types of light weapons, creating a realistic trigger pressing feel. This solves the problems of resistance distortion and large fluctuations in existing simulation equipment, ensuring that the training effect can be directly connected to live-fire operation. 2. Real-time graded speed feedback mechanism: The high-precision speed detection module quantifies the pressing speed and fluctuation, and combined with red, yellow and green indicator lights and buzzer prompts, it provides trainees with intuitive and real-time action feedback, replacing traditional verbal instructions. This allows trainees to quickly perceive their own action deviations, make targeted adjustments to finger force, and greatly improve the efficiency of muscle memory formation. 3. High adaptability of tiered training: The control module can preset multiple sets of speed parameters and supports manual adjustment of the benchmark range and stability threshold. It can adapt to different training stages (initial introductory, intermediate intensive, and advanced precision) and different training objectives (precision shooting, rapid shooting), meeting the training needs of different groups such as military and police personnel and shooting athletes. It has a wide range of applications. 4. Simple structure and high practicality: The overall module has a high degree of integration and is small in size. It can be used handheld or fixedly without the need for live ammunition. The training cost is low and the safety is high. At the same time, it is easy to operate and can be trained without the guidance of professional technicians, which facilitates its promotion and application. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments. The following embodiments are used to illustrate the present invention but are not limited to the scope of protection of the present invention.

[0018] This embodiment provides a light weapons shooting finger technique training simulator, the specific structure of which is as follows: Simulated trigger module: Made of stainless steel, its shape replicates the trigger of the Type 92 pistol. The arc-shaped contact surface is polished smooth. The pressing stroke is set to 3mm (consistent with the Type 92 pistol trigger stroke). A return spring is set at the bottom, which can automatically return to its original position after pressing. The return force is linked to the resistance adjustment module to ensure smooth return.

[0019] Resistance adjustment module: It uses a manual adjustment knob, paired with a disc spring assembly (composed of 3 stacked disc springs), with an adjustment range of 0.5-3N (suitable for pistol training) and an adjustment step of 0.1N. The resistance sensor uses a miniature pressure sensor (model FSR402), installed between the spring and the transmission rod, to collect resistance signals in real time and transmit them to the control module. The control module uses a built-in algorithm to fine-tune the spring preload to maintain stable resistance, with the error controlled within ±3%.

[0020] Speed ​​detection module: Uses a laser displacement sensor (model KEYENCE LK-G80) with a measurement accuracy of 0.01mm. It is installed directly below the analog trigger module, 5cm away from the bottom of the trigger. The timer is a high-precision timer built into the microcontroller with a timing accuracy of 1ms. Displacement and time data are collected every 10ms and transmitted to the control module for calculation.

[0021] Control module: Uses STM32F103 microcontroller with built-in Flash memory (stores 3 sets of preset parameters: Precision mode: base speed 0.2-0.5cm / s, stability threshold ≤10%; Advanced mode: base speed 0.3-0.6cm / s, stability threshold ≤8%; Fast mode: base speed 0.5-1.0cm / s, stability threshold ≤15%), and 3 external buttons (mode switch button, parameter increment button, parameter decrement button) for adjusting training parameters.

[0022] Audio-visual feedback module: Three high-brightness LED indicator lights (green LED, red LED, and yellow LED) are installed on the top of the simulator shell. The buzzer is an active buzzer with a working voltage of 5V, a high-frequency warning audio rate of 2kHz, and a mid-frequency prompt audio rate of 1kHz. The buzzer does not work when there is no qualified feedback.

[0023] Shell and mounting bracket: The shell is made of ABS material and measures 15cm×8cm×5cm. The sides are textured with anti-slip material for easy grip. The mounting bracket is a foldable metal bracket with an adjustable angle of 0-90°. It can be fixed to a desktop or the trigger position of a simulated gun to simulate a real grip posture.

[0024] Based on the training method of the simulator described above, the specific steps for finger technique training in pistol precision shooting are as follows: S1: The trainee selects the precision mode and sets the resistance value to 1.5N (compatible with the trigger resistance of the Type 92 pistol) using the resistance adjustment knob. The control module starts the resistance closed-loop control, the resistance sensor provides real-time feedback on the resistance value, and the microcontroller automatically fine-tunes the spring preload to maintain the resistance stable at 1.5N±0.045N.

[0025] S2: The trainee fixes the simulator to the table with a fixed bracket, holds the simulator shell in the posture of shooting a pistol, with the arm hanging naturally, the wrist fixed, the index finger placed on the simulated trigger, and the body posture is stable.

[0026] S3: The trainee slowly presses the simulated trigger, the laser displacement sensor collects the trigger displacement signal in real time, the timer records the time synchronously, and transmits a set of data to the microcontroller every 10ms (such as displacement 0.1mm, time 10ms; displacement 0.2mm, time 20ms, etc.).

[0027] S4: The microcontroller calculates the instantaneous speed based on the data (speed = displacement change / time change), and calculates the speed change rate between two adjacent sets of data (speed change rate = <current speed - previous speed> / previous speed × 100%). If the instantaneous speed is between 0.2-0.5 cm / s throughout the entire process, and the speed change rate is ≤10%, the green light illuminates; if the speed reaches 0.6 cm / s at a certain moment (exceeding the upper limit), and the speed change rate reaches 12% (exceeding the threshold), the red light illuminates and a 2kHz high-frequency beep is emitted; if the speed drops to 0.15 cm / s at a certain moment (below the lower limit), and the speed change rate reaches 11%, the yellow light illuminates and a 1kHz medium-frequency beep is emitted.

[0028] S5: Trainees adjust their finger pressure according to the indicator lights and beeping prompts. When the red light is on, they slow down the pressing speed, control the finger muscles to exert force evenly, and reduce speed fluctuations. When the yellow light is on, they moderately increase the speed while maintaining stable force. When the green light is on, they maintain the current pressing rhythm and repeat the pressing-reset action. Each training session lasts 20 minutes, twice a day, and continues for one month. After this, stable trigger pressing muscle memory can be formed, and the pressing speed fluctuation can be controlled within 8%, which is suitable for the precision shooting requirements of live guns.

[0029] It should be noted that the resistance adjustment range, speed reference range, stability threshold and other parameters of the present invention can be adjusted according to actual training needs. The elastic element can also be replaced by a helical spring, rubber damping element or the like. The speed detection module can also use a Hall sensor instead of a laser displacement sensor. As long as the core function of the present invention can be achieved, it is within the protection scope of the present invention.
