[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 5 and Figure 6 , an impact-triggered TNT charge mounting magazine 10 with three-level insurance is provided in an embodiment of the present application. The mounting magazine 10 includes a housing 100, an insurance device 120, a detonation device 140, and a tactical slide rail 160. The housing 100 includes a warhead housing 101 and a charge chamber housing 102. The insurance device 120 and the detonation device 140 are located inside the warhead housing 101. The tactical slide rail 160 is located at the outer top of the charge chamber housing 102. A warhead is further provided inside the warhead housing 101. The charge chamber housing 102 is used to load TNT charges and steel ball fragments; the insurance device 120 includes a physical switch insurance 121, a delay circuit insurance 122, and an impact electronic insurance 123. The physical switch insurance 121 is configured to manually control the start and interruption of the detonation device 140, and the physical switch insurance 121 constitutes the first-level insurance of the insurance device 120; the delay circuit insurance 122 is internally provided with a delay circuit with an adjustable time, and the delay time of the delay circuit can be modified through codes. The delay circuit insurance 122 constitutes the second-level insurance of the insurance device 120; the impact electronic insurance 123 is configured to trigger the detonation device 140 after the expiration of the delay time determined by the delay circuit, and the impact electronic insurance 123 constitutes the third-level insurance of the insurance device 120.
[0031] Among them, the warhead housing 101 is detachably connected to the charge chamber housing 102. A warhead is provided inside the warhead housing 101. The warhead can trigger the detonation device 140 inside the warhead housing 101 to explode upon impact. In some possible implementation manners, the warhead can be a guided warhead, which is used to guide the flight direction after the mounting magazine 10 detaches from the unmanned aircraft, so as to fly precisely towards the target explosion point. The TNT charges and steel ball fragments inside the charge chamber housing 102 are mainly used to increase the explosion power when an explosion occurs.
[0032] Specifically, the insurance device 120 includes three-level insurance, namely a physical switch insurance 121, a delay circuit insurance 122, and an impact electronic insurance 123, which is used to prevent the TNT from being accidentally triggered and exploded. The delay circuit insurance 122 is internally provided with a delay circuit with an adjustable time. When the physical switch insurance 121 is closed, within the set delay time, the signal lamp shows a green light. When the impact electronic insurance 123 is touched, the TNT does not explode. After the expiration of the delay time, the signal lamp shows a red light. When the impact electronic insurance 123 is touched, the TNT explodes. Whether the delay ends or not, when the physical switch insurance 121 is disconnected, the detonation device 140 is automatically interrupted, and when the physical switch insurance 121 is closed again, the delay is re-recorded. For the detonation device 140, whether the delay of the insurance device 120 ends or not, as long as the detonation device 140 is not touched, no explosion will occur.
[0033] Please refer to again Figure 5 Regarding the delay circuit, considering the limited space inside the warhead, it is necessary to select a 3.7V lithium battery pack with a smaller size and a mini single-chip microcomputer compatible with its power supply voltage for project development. Therefore, the ESP32-C3-SuperMini single-chip microcomputer is selected as the main control to make a countdown fuse device 120. Due to the size limitation of this single-chip microcomputer, there are fewer GPIO pins, and the countdown time can only be written into the code and cannot be adjusted through an external button. The countdown time is displayed on a two-digit common anode digital tube. Because of the limited space inside the warhead, the 74HC595 chip is no longer used and is directly driven by GPIO. The Arduino framework and sevseg library are used in the code to configure the relevant pins. Regarding the code, the countdown is initialized to 30 seconds, and the timer interrupt is used to subtract 1 every second. The timer configuration of ESP32 can use hw_timer_t and the interrupt service routine. The digital tube display is updated in the loop function, and the countdown end is checked to trigger an alarm. Regarding the hardware connection part, specific GPIO pins need to be determined. Among them, the digital tube and LED need to be connected with current-limiting resistors, and the current-limiting resistors are selected as 100Ω. When the alarm function reaches 0 in the countdown, it triggers the GPIO to output a high level, and a buzzer and an LED need to be connected. Ensure that the alarm pin is correctly initialized and the output mode is set in the code. Summarize the steps: configure the sevseg library parameters, connect the GPIO pins, write the countdown logic and timer interrupt, and test the display and alarm functions. It is necessary to refer to the relevant code structure in the search results, especially the digital tube driving and timer usage parts. Specifically, 1. SevSeg library configuration: Use the COMMON_ANODE parameter to adapt to the common anode digital tube, digitPins correspond to the GPIO for digit selection, and segmentPins correspond to the GPIO for segment selection. 2. Dynamic scanning mechanism: The refreshDisplay() function refreshes the digital tube at a frequency of about 500Hz to avoid visible flicker to the naked eye. 3. Alarm trigger: After the countdown reaches zero, a high level is continuously output, and an external buzzer or LED circuit needs to be connected.
[0034] This fuse device 120 uses a domestic ESP32_c3_supermini single-chip microcomputer as the main control, writes the countdown code, drives the two-digit digital tube to display the countdown, lights up the red led after the countdown ends, and the buzzer starts to work.

[0040] (III) Calculation of current-limiting resistor
[0041] The driving voltage of the digital tube is 2V, and the working current is 20mA, that is, 0.02A. The output voltage of the GPIO pin is 3.7V. According to the voltage characteristics of the series circuit, the voltage across the current-limiting resistor is:
[0042] UR = 3.7V - 2V = 1.7V
[0043] According to Ohm's law, the current-limiting resistor can be obtained:
[0044] R = 1.7V / 0.02A = 85Ω
[0045] Therefore, it is more appropriate to select a 100Ω resistor in practical applications.
[0046] The detonation device 140 is used to detonate the TNT in the mounted magazine 10. It has a built-in trigger circuit for connecting a double-headed wire clamp. One end of the double-headed wire clamp is connected to an electronic match, and the ignition cap of the electronic match is connected to a detonator to achieve instant triggering of the instantaneous fuse to detonate the TNT. Or it can be connected to the detonator through a fuse to achieve a time delay. When the time delay ends, the unmanned drone hitting the target can trigger the detonation device 140 to detonate the TNT in the magazine and cause an explosion. The charge magazine housing 102 includes six cylindrical TNT charge columns and three steel ball fragment chambers, which can be used to load TNT charge columns and steel ball fragments. After the TNT is detonated, the fragments are pushed by the shock wave overpressure for killing. The outer shell 100 includes a warhead housing 101 and a charge magazine housing 102. The warhead housing 101 is used to accommodate the safety device 120 and the detonation device 140, and the charge magazine housing 102 is used to load TNT charge columns and steel ball fragments. Its tail fins at the tail are used to stabilize the flight attitude of the charged magazine. The tactical slide rail 160 is fixed on the top of the charge magazine and can be used to quickly mount the magazine 10. The technical solution of the present application can ensure that the operator can safely achieve the goal of the unmanned drone carrying a bomb to strike the target.
[0047] The embodiment of the present application provides an impact-triggered TNT charge-mounted magazine 10 with three-level insurance. The mounted magazine 10 includes a housing 100, an insurance device 120, a detonation device 140, and a tactical slide rail 160. The housing 100 includes a warhead housing 101 and a charge chamber housing 102. The insurance device 120 and the detonation device 140 are located inside the warhead housing 101, and the tactical slide rail 160 is located at the outer top of the charge chamber housing 102. The charge chamber housing 102 is used to load TNT charges and steel ball fragments. The insurance device 120 includes a physical switch insurance 121, a delay circuit insurance 122, and an impact electronic insurance 123. The physical switch insurance 121 is configured to manually control the start and interruption of the detonation device 140, and the physical switch insurance 121 constitutes the first-level insurance of the insurance device 120. The delay circuit insurance 122 is built with an adjustable-delay circuit, and the delay circuit insurance 122 constitutes the second-level insurance of the insurance device 120. The impact electronic insurance 123 is configured to trigger the detonation device 140 after the delay time determined by the delay circuit ends, and the impact electronic insurance 123 constitutes the third-level insurance of the insurance device 120. By setting three-level insurance, including both the physical switch insurance 121 and the electronic insurance, it can provide better protection for the mounted magazine 10, prevent the accidental touch and explosion of TNT, avoid accidental explosion and injury accidents when the drone is flying at high speed, and greatly improve the safety of ammunition on the drone. In addition, by increasing the variable delay, within the delay range, it can fully ensure the safety of ammunition, and even if the fuse is touched, no explosion will occur, thus ensuring the safety of the operator and achieving the expected combat purpose at the same time.
[0048] In some embodiments, after closing the physical switch insurance 121, before the delay time determined by the delay circuit in the delay circuit insurance 122 ends, touching the impact electronic insurance 123 will not detonate the TNT charge; after the delay time determined by the delay circuit in the delay circuit insurance 122 ends, touching the impact electronic insurance 123 will detonate the TNT charge; regardless of whether the delay time determined by the delay circuit in the delay circuit insurance 122 ends, disconnecting the physical switch insurance 121 will automatically interrupt the detonation device 140. When the physical switch insurance 121 is closed again, the delay circuit in the delay circuit insurance 122 will re-record the delay time.
[0049] Specifically, the physical switch fuse 121 can be regarded as a general fuse. When the physical switch fuse 121 is in the open state, the detonation device 140 will not be detonated under any circumstances. When the physical switch fuse 121 is in the closed state and the delay time determined by the delay circuit of the delay circuit fuse 122 has not elapsed, the detonation device 140 can be interrupted in time by opening the physical switch fuse 121, and the delay circuit fuse 122 can be put into an invalid state by opening the physical switch fuse 121. When the physical switch fuse 121 is closed again, the delay circuit in the delay circuit fuse 122 will record the delay time again and enter the timing state again. At this time, if the physical switch fuse 121 is kept closed all the time, then when the re-timing reaches, touching the impact electronic fuse 123 will detonate the TNT charge. Thus, it can be seen that the physically controlled physical switch fuse 121 plays a leading and crucial role in the three-stage fuse. The other delay circuit fuse 122 is used as an auxiliary for the timing function and plays an auxiliary role when the impact electronic fuse 123 is touched. The three work together to improve the safety of the mounting magazine 10.
[0050] In some other embodiments, the physical switch fuse 121 controls the start and interruption of the delay circuit fuse 122. The delay circuit fuse 122 is electrically connected to the impact electronic fuse 123. After the delay time determined by the delay circuit in the delay circuit fuse 122 ends, the impact electronic fuse 123 triggers the detonation device 140.
[0051] Specifically, the physical switch fuse 121 plays a crucial control role in the start and interruption of the delay circuit fuse 122. For example, when the physical switch fuse 121 is open, the delay circuit fuse 122 can be made invalid and will not function at all. The physical switch fuse 121 can only make the delay circuit fuse 122 function when it is connected. Further, the delay circuit in the delay circuit fuse 122 also plays a certain degree of control role on the impact electronic fuse 123. When the delay time determined by the delay circuit in the delay circuit fuse 122 ends, the impact electronic fuse 123 will trigger the detonation device 140; before the delay time determined by the delay circuit in the delay circuit fuse 122 elapses, the impact electronic fuse 123 will not trigger the detonation device 140.
[0052] Please refer to again Figure 6, in some other embodiments, the detonating device 140 includes a trigger circuit 141, a double - headed wire clamp 142, an electronic match 143, and a detonator 144. The trigger circuit 141 is built into the detonating device 140 and is used to connect to the double - headed wire clamp 142. One end of the double - headed wire clamp 142 is connected to the electronic match 143, and the ignition cap of the electronic match 143 is connected to the detonator 144, which is used to achieve an instantaneous fuse or a time - delay fuse to detonate the TNT charge.
[0053] Please continue to refer to Figure 7 , the trigger circuit 141 is powered by a 3.7V rechargeable lithium - battery pack. After turning on the main power switch, the power - on indicator light comes on (green LED), and at the same time, the delay module starts to work. The delay time is controlled by an adjustment knob (the delay - time adjustment range is from 1 second to 2 minutes and 30 seconds). Before reaching the predetermined delay time, the OUT pin outputs a high level and the danger indicator light goes out (red LED); after reaching the predetermined delay time, the OUT pin outputs a low level and the danger indicator light comes on (red LED). At this time, if the "warhead touch switch" is turned on, the electronic match 143 will be ignited, thus detonating the detonator 144, and then detonating the TNT.
[0054] Among them, the double - headed wire clamp 142 is a tool for connecting or fixing wires and is usually used in fields such as electrical engineering and electronic - equipment maintenance. Its characteristic is that there are clamping devices at both ends, which can connect two wires at the same time or fix the wire to other components. The double - headed wire clamp 142 includes a chuck, an insulating handle, and a spring mechanism. There is a chuck at each end of the double - headed wire clamp 142 for clamping the wire, which is usually made of metal and has good electrical conductivity and mechanical strength. The insulating handle is arranged between the two chucks and is usually wrapped with insulating material to prevent electric shock and ensure safe operation. A spring mechanism is usually installed inside the chuck to make the chuck automatically close and firmly clamp the wire. By operating the insulating handle, the spring mechanism opens the chuck. After putting the wire in and releasing the insulating handle, the chuck automatically closes and clamps the wire tightly. The double - head design can fix two wires at the same time or fix the wire to other components, and is suitable for scenarios that require a stable connection.
[0055] The electronic match 143 is a device that uses electrical energy to generate high temperature or sparks and is used to ignite combustibles such as candles and gas stoves. Compared with traditional matches, the electronic match 143 is safer and is for single - use. The electronic match 143 includes an ignition lead and a tungsten - wire ignition head.
[0056] The percussion cap 144 is a device used to detonate explosives and is widely applied in the mining, building demolition, and military fields. It initiates the main explosive charge through an initial flame or spark. The percussion cap 144 activates the primer through a fuse, detonating the booster charge and the main charge in sequence to achieve a large-scale explosion. Its structure includes a shell, primer, booster charge, main charge, and fuse, and it is widely used in the mining, construction, and military fields. Fuse activation: The fuse is activated through an electrical signal, flame, or impact. The fuse ignites the primer, generating an initial explosion. The explosion of the primer triggers the booster charge, enhancing the explosion effect. The explosion of the booster charge finally detonates the main charge, producing a large-scale explosion.
[0057] In some other embodiments, the detonating device 140 is located at the front end of the warhead shell 101, and the double-headed wire clamp 142, the electronic match 143, and the percussion cap 144 are fixed inside the detonating device 140.
[0058] Specifically, the detonating device 140 is located at the front end of the warhead shell 101 to ensure that the explosion energy is released forward, maximizing the destruction effect. The warhead shell 101 is made of 3D printing material to withstand the explosion impact and external pressure. The detonating device 140 is located at the center of the front end of the warhead shell 101 to ensure uniform distribution of the explosion energy. The detonating device 140 includes a shell, an internal fixing frame, and connecting components. The shell is made of 3D printing material and is easily damaged by impact to facilitate the ejection of fragments such as steel balls and steel nails in the magazine. The double-headed wire clamp 142 is fixed inside the detonating device 140 near the front end to ensure the shortest electrical connection with the electronic match 143 and the percussion cap 144, reducing signal delay. The double-headed wire clamp 142 constitutes a circuit connecting the electronic match 143 and the percussion cap 144 to ensure the smooth passage of current. The electronic match 143 is fixed inside the detonating device 140, near the double-headed wire clamp 142, to ensure a quick response. The electronic match 143 generates high temperature or sparks through current to ignite the primer of the percussion cap 144. The percussion cap 144 is fixed at the rear end inside the detonating device 140, near the main charge, to ensure effective transmission of the explosion energy. The percussion cap 144 is detonated by the flame or sparks of the electronic match 143, triggering the booster charge and the main charge in sequence. This design ensures the efficiency and reliability of the detonation process and is suitable for occasions requiring precise detonation.
[0059] In some other embodiments, the detonating device 140 further includes a fuse 145, and the fuse 145 is connected between the electronic match 143 and the percussion cap 144 to achieve a delay fuse. The fuse 145 is connected between the electronic match 143 and the percussion cap 144 and is fixed inside the detonating device 140 to ensure the smooth transmission of flame or sparks. The fuse 145 is used to achieve a delay fuse and controls the explosion delay through the burning time. It is usually made of flammable chemical substances and has a stable burning speed.
[0060] Current is transmitted from an external power source through the double - headed wire clamp 142 to the electronic match 143. After the electronic match 143 is powered on, it generates high temperature or sparks, igniting the fuse 145. The fuse 145 starts to burn, and the burning time is determined by the length and material of the fuse 145, realizing a time - delay fuse. When the fuse 145 burns to the detonator 144, the flame or sparks detonate the detonator 144, successively triggering the booster charge and the main charge. The explosion of the detonator 144 triggers the main charge, generating a large - scale explosion. The time - delay fuse is realized through the fuse 145, ensuring the efficiency and reliability of the detonation process, and is applicable to occasions that require precise time - delay detonation. The positional relationship and structural design of each component ensure the smooth transmission of current and flame, thus achieving a safe and reliable explosion effect.
[0061] In some other embodiments, the charge chamber housing 102 includes a TNT charge column chamber 1021 and a steel ball fragment chamber 1022. The TNT charge column chamber 1021 includes six cylindrical TNT charge column chambers 1021 for loading TNT charge columns; the steel ball fragment chamber 1022 includes three steel ball fragment chambers 1022 for loading steel ball fragments. After the TNT charge column is detonated, the fragments are pushed to cause damage through the shock wave overpressure.
[0062] Specifically, the charge chamber housing 102 is usually made of high - strength metal (such as steel or titanium alloy) to withstand the explosion shock and external pressure. The charge chamber housing 102 is divided into two parts. The front part is the TNT charge column chamber 1021, and the rear part is the steel ball fragment chamber 1022. The TNT charge column chamber 1021 includes six cylindrical TNT charge column chambers 1021, which are evenly distributed in the front part of the charge chamber housing 102 and are symmetrically arranged around the central axis. It is used to load TNT charge columns and provide the main explosion energy. Each TNT charge column chamber 1021 is cylindrical with a smooth interior to ensure the stable placement of the TNT charge column. The steel ball fragment chamber 1022 includes three steel ball fragment chambers 1022, which are located in the rear part of the charge chamber housing 102 and are evenly distributed behind the TNT charge column chamber 1021. It is used to load steel ball fragments and push the fragments to cause damage through the explosion shock wave. Each steel ball fragment chamber 1022 is cylindrical and contains a large number of small steel balls to ensure the even distribution of the fragments. The TNT charge column is detonated by a detonating device 140 (such as the detonator 144), generating huge explosion energy. The shock wave overpressure generated by the explosion of the TNT charge column propagates forward, pushing the steel ball fragments. The shock wave overpressure pushes the steel ball fragments to fly out at high speed to cause damage to the target. Through the combination of the TNT charge column and the steel ball fragments, an efficient explosion and damage effect are achieved. The positional relationship and structural design of the TNT charge column chamber 1021 and the steel ball fragment chamber 1022 ensure the effective transmission of the explosion energy and the even distribution of the fragments, and are applicable to occasions that require high - explosion and damage effects.
[0063] In some other embodiments, the mounted magazine 10 further includes a fin device 180. The fin device 180 is located at an end of the charge chamber housing 102 away from the warhead housing 101. The fin device 180 includes N fins, where N is an even number greater than or equal to 4. The N fins are evenly distributed on the outer peripheral side of the charge chamber housing 102. Among them, the tail fin device 180 at the tail is used to stabilize the flight attitude of the mounted magazine 10. Among them, N can be 4. By setting the number of fins to an even number of 4 or more, the way of hitting the loaded ammunition can be changed to a throw, and the flight stability of the mounted magazine 10 can be achieved.
[0064] The fin device 180 is located at an end of the charge chamber housing 102 away from the warhead housing 101, that is, at the tail of the mounted magazine 10. It includes N fins, and N is an even number greater than or equal to 4. Usually, there are 4, 6, or 8 fins, and the specific number is determined according to the design requirements. The N fins are evenly distributed on the outer peripheral side of the charge chamber housing 102 and are symmetrically arranged around the central axis. The shape of the fins is usually trapezoidal or triangular, with an appropriate aerodynamic design to provide a stable flight attitude. Through the aerodynamic principle, flight stability is provided to ensure that the mounted magazine 10 maintains a predetermined trajectory during flight.
[0065] Through the combination of the charge chamber housing 102 and the fin device 180, an efficient explosion killing effect and a stable flight attitude are achieved. The positional relationship and structural design of the charge chamber housing 102 and the fin device 180 ensure the effective transfer of explosion energy and flight stability, and are applicable to occasions that require a high explosion killing effect and an accurate flight trajectory.

The power system includes motors, propellers, and batteries, which provide the power required for flight. The communication system includes a radio receiver and a transmitter, which are used to communicate with the ground control station. The main body of the drone provides flight and control functions to ensure that the drone can fly along a predetermined trajectory. The mounted magazine 10 is located at the bottom of the main body of the drone and is selectively loaded through the tactical slide rail 160. The tactical slide rail 160 is usually made of high-strength metal (such as aluminum alloy), with appropriate mechanical strength and lightweight design. Through the tactical slide rail 160 mechanism, the quick loading, unloading, and fixation of the mounted magazine 10 are realized to ensure the stable connection of the mounted magazine 10 during flight.
[0068] Specifically, the drone includes the main body of the drone and the mounted magazine 10. The main body of the drone is located at the upper part of the drone, including a flight control system, a power system, and a communication system.

The tactical slide rail 160 is located at the bottom of the main body of the drone and is used to load and fix the mounted magazine 10.
[0069] The main body of the drone controls the flight attitude and trajectory through the flight control system to ensure that the drone flies along a predetermined route. The mounted magazine 10 is selectively loaded at the bottom of the main body of the drone through the tactical slide rail 160 to ensure a stable connection. After the drone reaches the target area, the TNT charge in the mounted magazine 10 is detonated through the detonating device 140, generating a huge explosion energy and fragment killing effect. The tail fin device 180 of the mounted magazine 10 provides flight stability through the principle of aerodynamics to ensure that the drone maintains a predetermined trajectory during flight. Through the combination of the main body of the drone and the mounted magazine 10, efficient flight control and explosion killing effects are achieved. The positional relationship and structural design of the main body of the drone and the mounted magazine 10 ensure high flight mobility and effective transmission of explosion energy, and are suitable for occasions that require high explosion killing effects and precise flight control.
