[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0044] Reference Figure 1 As shown, the present invention discloses a simulated shooting training device, comprising:

[0045] A gun body 100, wherein a protective ring 101 is provided on the surface of the gun body 100, and a trigger 102 is provided inside the protective ring 101;

[0046] Reference Figure 2As shown, the firing assembly 200 includes a first control module 201 and a sensor group 202. The first control module 201 is disposed on the surface of the gun body 100, and the sensor group 202 is electrically connected to the first control module 201. The sensor group 202 includes a start sensor 2021, a first flash sensor 2022, a second flash sensor 2023, and a firing sensor 2024. The start sensor 2021, the first flash sensor 2022, the second flash sensor 2023, and the firing sensor 2024 are sequentially disposed within the retaining ring 101 along the movement trajectory of the trigger 102.

[0047] Reference Figures 3-7 As shown, the detonation assembly 300 includes a housing 301, a drum magazine 302, a firing pin 303, a sliding plate 304, an escapement 305, a drive source 306, and a second control module 307. The housing 301 is connected to the gun body 100. The drum magazine 302 is disposed at one end of the housing 301. An elastic element 308 is disposed between one end of the firing pin 303 and the housing 301. The other end of the firing pin 303 faces the drum magazine 302. A locking platform 3031 is disposed on the surface of the firing pin 303. The sliding plate 304 is disposed below the firing pin 303. The surface is provided with a spring piece 3041; the escapement 305 is disposed above the firing pin 303 and rotatably connected to the housing 301, and the escapement 305 is fastened to the locking plate 3031; the drive source 306 is disposed at the end of the housing 301 away from the drum 302, the drive source 306 drives the slide plate 304 to make the spring piece 3041 drive the escapement 305 to rotate, and the elastic element 308 releases the firing pin 303 to abut against the drum 302; the second control module 307 is disposed on the housing 301, and the second control module 307 is electrically connected to the drive source 306 and the first control module 201 respectively;

[0048] Reference Figures 8-9 As shown, a recoil assembly 400 is disposed at the muzzle end 103 of the gun body 100. The recoil assembly 400 includes a base plate 401, a push plate 402, an electric actuator 403, a pressure block 404, and a third control module 405. A first torsion spring 406 is hinged between the push plate 402 and the base plate 401. The pressure block 404 is hinged to the base plate 401. The electric actuator 403 is disposed on the base plate 401 and drives the pressure block 404 to rotate, thereby pressing the pressure block 404 against the push plate 402. The third control module 405 is disposed on the base plate 401 and is electrically connected to the electric actuator 403 and the first control module 201.

[0049] In this invention, a trigger 102 is provided inside the protective ring 101 on the surface of the gun body 100. Pulling the trigger 102 realizes the firing action. The gun body 100 serves as a supporting component, and the firing assembly 200 and the blast assembly 300 are installed on the surface of the gun body 100. The recoil assembly 400 is placed at the port of the gun body 100.

[0050] The sensor group 202 in the firing assembly 200 is installed inside the retaining ring 101, directly opposite the trigger 102. The first control module 201 is installed near the retaining ring 101. The sensor group 202 detects the position of the trigger 102 to determine whether the trigger 102 is in the firing position. In actual operation, after the operator pulls the trigger 102 to the firing position, the sensor group 202 feeds back the detection signal to the first control module 201. The first control module 201 then feeds back the signal to the blast assembly 300 and the recoil assembly 400. This ensures the synchronization of the blast sound and recoil force while the trigger 102 is pulled, improving the realism of the simulated shooting. To further ensure the synchronization of recoil and bang, the sensor group 202 in this invention includes multiple detection sensors, subdividing the trajectory of the trigger 102 into four segments. By activating sensor 2021, primary ignition sensor 2022, secondary ignition sensor 2023, and firing sensor 2024, the time it takes for the trigger 102 to reach the actual firing position can be predicted, and the signals sent to the recoil assembly 400 and bang assembly 300 can be advanced, so that at the same time as firing, the bang sound can be heard and the recoil feedback can be received, making the simulation more realistic. As a preferred embodiment of this invention, a reflector or neodymium magnet is fixed to the tip of the trigger 102, and a photoelectric transmitting and receiving sensor or Hall sensor is arranged at the corresponding position of the trigger guard to achieve accurate detection of the trigger 102 pull signal.

[0051] The housing 301 in the detonation assembly 300 serves as a support member, and the housing 301 is detachably connected to the gun body 100. The firing pin 303 in the detonation assembly 300 moves and impacts the ammunition in the drum magazine 302, producing a detonation sound and emitting the smell of gunpowder. The function of the escapement 305 is to store and fix the firing pin 303 and release the firing pin 303. Specifically, the firing pin 303 moves to compress the elastic element 308 to store force. The locking plate 3031 on the probe surface cooperates with the escapement 305 to fix the firing pin 303 after it has been stored. The drive source 306 drives the slide plate 304 to move along the direction of the firing pin 303. The surface of the slide plate 304 is provided with a spring plate 3041. When the slide plate 304 moves, it drives the spring plate 3041 to move synchronously. The spring plate 3041 drives the escapement 305 to rotate. The escapement 305 releases the fixing of the firing pin 303. The elastic element 308 extends and drives the firing pin 303 to be released, so that the firing pin 303 can collide with the ammunition in the magazine 302. The control process is as follows: After the first control module 201 detects the firing signal, the first control module 201 sends the signal to the second control module 307. The second control module 307 controls the drive source 306 to move, causing the slide plate 304 to move, so that the spring 3041 abuts against the escapement 305, and the escapement 305 rotates to complete the firing action.

[0052] A recoil assembly 400 is located at the muzzle end 103 to release recoil force to the gun body 100, simulating the recoil force generated by the gun body 100 during firing. Specifically, the base plate 401 and the push plate 402 are hinged together, and a first torsion spring 406 is provided at the hinge. Through the elastic potential energy of the first torsion spring 406, the push plate 402 can be flipped, and the push plate 402 flips and strikes the muzzle to simulate recoil force. Before flipping, the push plate 402 is fastened inside the base plate 401 and pressed by the pressure block 404. The extension and retraction of the electric actuator 403 drives the pressure block 404 to flip, and the pressure block 404 moves away from the push plate 402, thus releasing the push plate 402. The control process is as follows: After the first control module 201 detects the firing signal, it sends the control signal to the third control module 405. The third control module 405 controls the electric push rod 403 to extend, which drives the pressure block 404 to flip. The push plate 402 releases the impact muzzle, realizing the output of recoil force.

[0053] This invention uses a sensor array 202 to detect the firing position of the trigger 102 and sends the detection signal to the blast assembly 300 and the recoil assembly 400. The blast assembly 300 can simulate the blast sound of a live round being fired and also produces the smell of gunpowder after firing, highly replicating a real shooting scenario. The recoil assembly 400 can forcefully strike the barrel from the front, simulating a realistic recoil effect and creating an immersive shooting experience for the user. This invention provides high-quality simulation training, facilitating prior familiarization with the shooting process and state. At the same time, it reduces the frequency of live-fire shooting, avoids the cumbersome procedures and potential accident risks in live-fire shooting, and balances training effectiveness and safety.

[0054] As a preferred embodiment of the present invention, the first control module 201, the second control module 307, and the third control module 405 are all single-chip microcomputer control modules, equipped with lithium battery power. Furthermore, the first control module 201 is communicatively connected to the second control module 307 and the third control module 405, respectively, to transmit signals via 2.4G or wired communication. In addition, the first control module 201 is also equipped with a storage unit to store and trace data, facilitating the monitoring of firing data.

[0055] Furthermore, the output end of the drive source 306 is provided with a first drum 309, and the first drum 309 is connected to the slide plate 304 by a rope 310.

[0056] Specifically, a rope 310 is wound around the surface of the drum 309, and the drum 309 is connected to the slide plate 304 through the rope 310. The drive source 306 drives the drum 309 to rotate, thereby realizing the movement of the slide plate 304.

[0057] Furthermore, a return spring 311 is provided at the end of the slide plate 304 away from the drive source 306, and the return spring 311 is connected to the housing 301.

[0058] Specifically, in actual operation, in order to achieve continuous popping sounds from continuous firing, after firing, the return spring 311 drives the slide plate 304 to move in the opposite direction, so that the slide plate 304 returns to its initial state, thus enabling multiple firing actions.

[0059] Furthermore, referring to Figure 5 As shown, a boss 3032 is provided on the surface of the slide plate 304 away from the drive source 306. The slide plate 304 moves along the axial direction of the striker 303, so that the boss 3032 abuts against the mounting plate 3031.

[0060] In actual operation, the drive source 306 drives the slide plate 304 to move. The protrusion 3032 on the surface of the slide plate 304 abuts against the locking platform 3031 on the surface of the firing pin 303, driving the firing pin 303 to move towards the elastic element 308 and compressing the elastic element 308. When it moves to the bottom of the escapement 305, the escapement 305 engages with the locking platform 3031, fixing the locking platform 3031 in place. At this point, the charging of the firing pin 303 is completed. As a preferred embodiment of the present invention, the drive source 306 drives the slide plate 304 to complete two stages of travel. The first stage drives the firing pin 303 to move, realizing the charging of the firing pin 303. The second stage drives the slide plate 304 to abut against the escapement 305, realizing the firing action of the firing pin 303. This achieves the simultaneous completion of charging and firing actions by a single drive source 306, reducing manufacturing costs and shrinking the size of the bang assembly 300.

[0061] Furthermore, referring to Figure 4 As shown, the escapement 305 includes an integrally formed latch 3051 and a firing plate 3052. The latch 3051 is disposed on the top of the firing pin 303 and cooperates with the latch 3031. The firing plate 3052 is disposed on the side near the spring 3041.

[0062] Specifically, the escapement 305 comprises two parts: a latch 3051 and a firing plate 3052. The latch 3051 is arranged perpendicular to the firing plate 3052. One end of the latch 3051 is used to cooperate with the locking plate 3031 of the firing pin 303 to fix the position of the firing pin 303 and put the firing pin 303 in a charged state. One end of the firing plate 3052 is used to cooperate with the spring 3041 to realize the firing action of the firing pin 303. Since the firing pin 303 is arranged parallel to the slide plate 304, as a preferred embodiment of the present invention, the latch 3051 is arranged perpendicular to the firing plate 3052.

[0063] Furthermore, a second torsion spring 312 is provided between the escapement 305 and the housing 301.

[0064] In actual operation, the second torsion spring 312 enables the escapement 305 to reset. After the firing action is completed, the escapement 305 returns to its initial state, preparing for the next charge of the firing pin 303. Specifically, one end of the second torsion spring 312 is connected to the bottom of the catch hook 3051, enabling the catch hook 3051 to move downwards, facilitating the engagement of the catch hook 3051 with the catch plate 3031. The other end is connected to the housing 301. Furthermore, the entire escapement 305 can only rotate in one direction. As a preferred embodiment of the invention, the firing plate 3052 has a guide ramp 3053 on the side near the drive source 306, facilitating the slide plate 304 to drive the spring 3041 through the firing plate 3052, thus avoiding obstruction to the reset of the spring 3041.

[0065] Furthermore, a first limit switch 313 and a second limit switch 314 are provided inside the housing 301. The first limit switch 313 and the second limit switch 314 are arranged at both ends of the slide plate 304 along the axial direction of the striker 303, and both the first limit switch 313 and the second limit switch 314 are electrically connected to the second control module 307.

[0066] Specifically, the first limit switch 313 and the second limit switch 314 are located at both ends of the slide plate 304 to detect whether the slide plate 304 is in position. In actual operation, the drive source 306 drives the slide plate 304 to move, and the drive spring 3041 then abuts against the first limit switch 313. It is determined that the slide plate 304 has effectively fired the firing pin 303. At this time, the drive source 306 reverses and releases the rope 310. The return spring 311 drives the slide plate 304 to move in the opposite direction. After the spring 3041 passes through the escapement 305, the slide plate 304 contacts the second limit switch 314 and sends a signal to the second control module 307. The slide plate 304 enters a standby state. After receiving the next power storage signal, the slide plate 304 is driven to move again.

[0067] Furthermore, referring to Figures 6-7 As shown, the popping component 300 also includes a servo motor 315, which is located on the side of the housing 301 near the popping drum 302. The servo motor 315 is electrically connected to the second control module 307. The output end of the servo motor 315 is provided with a toothed sprocket 316, and the surface of the popping drum 302 is provided with indexing teeth 317 that cooperate with the toothed sprocket 316.

[0068] In this invention, the magazine 302 can be circumferentially filled with multiple rounds of ammunition. The firing pin 303 strikes the magazine 302, fixing its position. Each time the firing pin 303 strikes the magazine 302, the magazine 302 rotates to switch to the position of the next round of ammunition. Specifically, a servo motor 315 controls the rotation of a crankset 316. The magazine 302 has indexing teeth 317 on its end face. The crankset 316 meshes with the indexing teeth 317, driving the magazine 302 to rotate, thus achieving automatic ammunition switching and enabling continuous firing training. As a preferred embodiment of this invention, the magazine 302 is detachably connected to the housing 301. After all the ammunition in the magazine 302 has been fired, the magazine 302 can be removed and reloaded.

[0069] Furthermore, referring to Figure 9 As shown, a guide groove 4041 is provided on one side of the pressure block 404, and a slide rod 410 is provided in the guide groove 4041. The extension and retraction of the electric push rod 403 is connected to the slide rod 410, and the extension and retraction of the electric push rod 403 drives the pressure block 404 to flip.

[0070] Furthermore, referring to Figure 8As shown, the recoil assembly 400 also includes a winch 407, which is electrically connected to the third control module 405. The winch 407 is mounted on the surface of the base plate 401, and the winch 407 is connected to the push plate 402 by a traction rope 408.

[0071] Specifically, the winch 407 enables the push plate 402 to reset and store power. In actual operation, the winch 407 drives the traction rope 408 to wind, causing the push plate 402 to fit against the base plate 401. As a preferred embodiment of the invention, the electric push rod 403 has an internal spring and is driven by an electromagnet. A brief energization of the electric push rod 403 causes it to extend, causing the pressure block 404 to reverse. Under the action of the internal spring, the electric push rod 403 automatically retracts after power is cut off, causing the pressure block 404 to return to its initial position. In this invention, a slot is provided on the side of the pressure block 404 that fits against the push plate 402, improving the reliability of the pressure block 404. Furthermore, a guide surface 4042 is provided on the surface of the pressure block 404. When the push plate 402 presses against the surface of the pressure block 404, the guide surface 4042 drives the pressure block 404 to rotate outwards to avoid it, and finally springs back to press the push plate 402 firmly.

[0072] Furthermore, the base plate 401 is provided with a proximity switch 409 that cooperates with the push plate 402, and the proximity switch 409 is electrically connected to the third control module 405.

[0073] Specifically, the winch 407 drives the push plate 402 to gradually approach the base plate 401. When the push plate 402 contacts the proximity switch 409, the proximity switch 409 sends a signal to the third control module 405, indicating that the push plate 402 has finished accumulating power. After the power accumulation is complete, the winch 407 reverses its direction to loosen the traction rope 408, so as not to hinder the rapid release of the push plate 402.

[0074] In actual firing, if the firing mechanism of the blast assembly 300, recoil assembly 400 and the gun body 100 itself is to be synchronized, multiple sensors need to be installed before the firing position. By collecting the movement speed of the trigger 102, the time it takes for the trigger 102 to reach the firing position is estimated, and signals are sent to each execution module in advance.

[0075] Reference Figures 10-13 As shown, a simulated shooting training method, applied to the simulated shooting training device, further includes the following steps:

[0076] S1. Test the delay time T of the popping component 300 respectively. 爆响 The delay time T of the recoil assembly 400 后坐 Calculate the time difference T between the bang assembly 300 and the recoil assembly 400. dif =T 后坐-T 爆响 ;

[0077] After the bang assembly 300 and recoil assembly were manufactured, the delay time of their firing mechanisms was tested to obtain the advance amount required to send the command, which is T. 爆响 and T 后坐 The time difference in their lead time is T. dif = T 后坐 - T 爆响 T dif The time difference is greater than 0, meaning the detonation component 300 moves faster than the recoil component 400. To compensate for this time difference, the first control module 201 sends firing commands to the detonation component 300 and the recoil component 400 in sequence, with a time difference of T. dif Through calibration, it is possible to feel the recoil when hearing a loud bang.

[0078] S2. Starting from the initial position, record the time point T1 from when trigger 102 is pulled to when sensor 2021 is activated, the trigger time point T2 from when the first fire sensor 2022 is activated, and the trigger time point T3 from when trigger 102 is pulled to when the second fire sensor 2023 is activated:

[0079] S3. The first control module 201 records T1, T2 and T3. Based on the position L1 of the start sensor 2021, the position L2 of the first fire sensor 2022 and the position L3 of the second fire sensor 2023, the trigger 102 is calculated by displacement and time.

[0080] S4. Based on the trigger 102's pulling speed and the firing sensor 2024's position L4, calculate the estimated time Tx for the trigger 102 to pull the trigger to the firing sensor 2024. Then, the recoil assembly firing command time is Ta = Tx - T. 后坐 At time Ta, the signal is sent to the third control module 405; then it waits for T. dif Then, the signal is sent to the second control module 307; Tx is the calculated ideal firing time point, that is, the first control module 201 sends the signal at this time point, which can realize that the recoil can be felt when the explosion is heard;

[0081] Note: If the calculated value of Ta is negative, it means that the trigger 102 is expected to reach the firing point earlier than the action of the third control module 405. This cannot be corrected by advance adjustment, and Ta can only be made to be 0 to minimize the expected time difference. If, during the design and actual testing phase, the trigger 102 is pulled at a normal speed, but the calculated value of Ta is less than 0, then the position of the second fire sensor 2023 needs to be appropriately moved forward in the mechanism design.

[0082] S5. When the trigger 102 passes the firing sensor 2024, the first control module 201 records the time T4 when the trigger 102 passes the firing sensor 2024, and completes the firing action of the trigger 102. At the same time, the popping sound and hammering action are completed.

[0083] S6. Based on the time T4 when the trigger 102 passes the firing sensor 2024 and the expected time Tx when the trigger 102 is pulled to the firing sensor 2024, obtain the calibration coefficient, and correct the next expected time when the trigger 102 is pulled to the firing sensor 2024 using the calibration coefficient.

[0084] In precision shooting, trigger 102 needs to be pulled slowly, and the speed varies greatly from person to person. The accuracy of the estimated time can also be affected by the deviation of the sensor installation position. Through calibration coefficients, it is possible to correct this and achieve a continuous and stable firing effect that synchronizes trigger pull, recoil, and blast.

[0085] The method for calculating Tx is as follows:

[0086] The distance between the firing sensor 2024 and the secondary firing sensor 2023 is: ΔL = L4 - L3

[0087] Predicted firing time ΔT = kΔL + b

[0088] Calibration correction prediction time Tx = ΔT × a

[0089] The calibration coefficient 'a' balances long-term wear and environmental differences and is obtained from the T4 collected from the previous firing record. The calibration of 'a' is updated by moving average. The more times the device is used, the more accurate the predicted Tx becomes.

[0090] Based on the data collected by T4, Tx actually equals T4.

[0091] Single calibration: a = Tx actual / Tx estimated = T4 / Tx estimated

[0092] Moving average: a = 0.9 × aold + 0.1 × anew

[0093] In the formula, k is the slope and b is the intercept. This can also be tested experimentally and in the field, and fitted using linear regression.

[0094] Travel difference: ΔL1 = L3 - L2, ΔL2 = L3 - L1 (corresponding to travel distances T3 - T2 and T3 - T1);

[0095] Time difference: ΔT1 = T3 - T2, ΔT2 = T3 - T1 (corresponding to the actual time difference between these two segments of the journey);

[0096] The least squares method can be used to calculate k and b. The simplified derivation of the formula is as follows:

[0097]

[0098]

[0099] In the above formula, n=2, and i represents the two sets of data corresponding to ΔL1 and ΔL2. As a preferred embodiment of the present invention, the first control module 201 is equipped with a memory that can record parameters L1, L2, L3, L4 and a. Before operation, the values ​​can be burned into the memory by the host computer to calculate the compensation time. With a time difference of milliseconds, the firing signals are sent to the bang component 300 and the recoil component 400 respectively.

[0100] In summary, this invention introduces a simulated shooting training device and method. The invention uses a sensor array 202 to detect the firing position of the trigger 102 and sends the detection signal to the blast assembly 300 and the recoil assembly 400. The blast assembly 300 simulates the blast sound of live ammunition firing and also produces the smell of gunpowder after firing, highly replicating a real shooting scenario. The recoil assembly 400 strikes the barrel forcefully from the front, simulating a realistic recoil effect, creating an immersive shooting experience for the user. This invention provides high-quality simulated training, facilitating prior familiarization with the shooting process and state. Simultaneously, it reduces the frequency of live ammunition firing, avoiding the cumbersome procedures and potential accident risks of live ammunition firing, balancing training effectiveness and safety. Furthermore, the sensor array 202 on the retaining ring 101 estimates the time it takes for the trigger 102 to reach the firing position by collecting the movement speed of the trigger 102 and sends signals to each execution module in advance, ensuring the synchronization of the blast assembly 300 and the recoil assembly 400, further improving the realism of the simulation.

[0101] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
