Description

Technical Field

[0001] This invention relates to the field of launching device technology, specifically to a spring-driven launching device for fire fighting, military and police use. Background Technology

[0002] Currently, launching devices are widely used in fields such as fire emergency rescue, police non-lethal response, and military equipment protection. Existing launching devices typically employ gunpowder ignition or high-pressure gas cylinder propulsion. However, gunpowder ignition carries the safety risk of gunpowder explosion, and the gunpowder is susceptible to failure due to environmental humidity and other factors, leading to launch malfunctions. High-pressure gas cylinder propulsion suffers from problems such as difficulty in controlling gas pressure, gas cylinder leakage, and limitations in transportation and storage. Furthermore, most existing launching devices are single-tube, single-launch structures with limited functionality, low operational efficiency, and difficulty in handling complex and changing operating environments. While a few multi-tube launching devices improve efficiency, they often have complex structures, fixed launch modes, poor adaptability, and lack effective safety locking mechanisms, making them prone to accidental launches. Therefore, there is an urgent need for a launching device that is compact, safe, reliable, multifunctional, and adaptable to various complex scenarios. Summary of the Invention

[0003] To address the problems of low safety, limited functionality, low operational efficiency, and poor adaptability in existing technologies, this application proposes a spring-driven launching device for firefighting, military, and police use. This device employs a multi-tube modular design combining spring power and mechanical drive, achieving safe, reliable, multifunctional integration, and efficient operation. To achieve the above objectives, the present invention adopts the following technical solution: A spring-driven launching device for firefighting, military, and police use includes a control unit, a drive unit, a housing, and one or more launching units. Each launching unit includes a launching tube, a pressure spring, and a launching element. The pressure spring is built into the launching tube for energy storage. Potential energy is stored and used to provide the driving force for launching by compressing or torturing the pressure spring. The launching element is installed inside the launching tube and is driven out when the pressure spring releases its potential energy. The drive unit is driven by a motor or mechanical drive. This method of storing potential energy through the compression or tortuosity of the pressure spring constitutes the core technical feature that distinguishes this invention from traditional gunpowder-based or high-pressure gas cylinder-based methods. Compared to the risks of explosion associated with gunpowder-based methods and their susceptibility to failure due to environmental humidity, and the difficulties in pressure control, leakage, and limited transportation and storage associated with high-pressure gas cylinders, the spring-driven method employed in this invention fundamentally avoids these safety hazards, significantly improving the safety and reliability of the device. Furthermore, the spring structure is simple to maintain, has a long service life, and can adapt to complex and harsh operating environments.

[0004] Preferably, the lower end of the outer casing is provided with a bracket mounting slot, and a drone mounting bracket for fixing to the drone can be detachably installed in the bracket mounting slot. This preferred solution, by setting a drone mounting bracket, enables the device to be mounted on a drone, realizing long-distance remote control launch, and is suitable for high-risk scenarios such as breaking windows in high-rise buildings and fire extinguishing.

[0005] Preferably, the control unit includes a control circuit board, a battery assembly, a switch assembly, and a display assembly that are electrically connected to each other. The drive unit is a stepper motor. The housing includes a control end cover and a tube body that are plugged into each other. The control end cover has a control chamber for accommodating the control circuit board, the battery assembly, and the drive unit. The stepper motor is fixedly mounted on a mounting plate provided in the control chamber. The rotating shaft of the stepper motor passes through a through hole in the mounting plate and connects to the transmitting unit for controlling the triggering of the transmitting unit.

[0006] Preferably, the control unit includes a wireless signal receiver connected to the control circuit board. When the wireless signal receiver receives an external control signal, it transmits the signal to the control circuit board, which then activates the drive unit to enable the transmitting unit to transmit.

[0007] Preferably, the control end cap and the tube body are mutually engaged via a snap-fit ​​assembly. The mounting plate has an axial threaded hole corresponding to the transmitting unit, and a threaded push rod is threaded into the axial threaded hole. The outer end of the threaded push rod abuts against the end of the transmitting unit, thereby limiting the axial degree of freedom of the transmitting unit. The threaded push rod can rotate relative to the threaded hole to adjust the protrusion dimension of the threaded push rod relative to the mounting plate, thus allowing it to abut against transmitting units of various lengths.

[0008] This preferred solution achieves precise control of the launch action through an integrated control unit design, while the plug-in housing structure facilitates component assembly and maintenance.

[0009] Preferably, the switching assembly includes a main power switch and a drive switch. The drive switch is connected to the control circuit board and the stepper motor, respectively, and is used to control the start and stop of the stepper motor. A display assembly and the main power switch are disposed at the end of the housing. The display assembly includes a voltage display. The housing is equipped with a laser sight. The main power switch is connected to the battery assembly, the drive switch, the laser sight, and the voltage display, respectively. The main power switch is used to control the connection and start / stop of the battery assembly with other components. The voltage display is disposed at the outer end of the housing. When the main power switch is activated, the battery assembly supplies power to the drive switch, the laser sight, and the voltage display. At this time, the drive switch can start controlling the drive motor, the laser sight emits the corresponding aiming laser, and the voltage display shows the current battery assembly voltage to prevent insufficient battery power. This preferred solution, by setting up a main power switch, a voltage display, and a laser sight, achieves centralized control of the circuit, real-time monitoring of power, and precise aiming of the launch, improving the convenience and reliability of use.

[0010] Preferably, the emitter is a solid emitter, a liquid emitter, or a smoke emitter. This preferred embodiment, through its modular emitter design, allows the device to be equipped with modules of different functions to meet various complex environments.

[0011] Preferably, the launching element is a solid launching element, which is a window-breaking tip rod. The outer end of the launching tube is connected to a first guide head, and the first guide head has a guide channel adapted to the outer diameter of the window-breaking tip rod.

[0012] Preferably, the surface of the window-breaking tip is provided with a guide spiral groove, which is adapted to a circular steel ball or guide pin inside the launch tube. This preferred solution has two main functions: First, the cooperation between the guide spiral groove and the steel ball or guide pin guides the window-breaking tip during launch, significantly improving launch accuracy. During launch, the projectile moves forward under thrust, and the interaction between the circular steel ball or guide pin and the guide spiral groove generates rotational resistance, forcing the projectile to rotate along the trajectory of the guide spiral groove, achieving a high-speed rotational attitude upon exiting the tube. Second, before launch, the mutual adaptation between the guide spiral groove and the steel ball or guide pin limits the axial freedom of the window-breaking tip, preventing it from sliding outwards and detaching from the launch device before launch.

[0013] Preferably, the end of the window-breaking tip is provided with a buffer assembly, which includes a fixed plate, an elastic rubber head, and multiple limiting slide rods. The fixed plate is fixedly connected to the window-breaking tip, and the multiple limiting slide rods are all connected to the fixed plate and the elastic rubber head. The multiple limiting slide rods are arranged in a circular array with the window-breaking tip as the center. Each of the multiple limiting slide rods is sleeved with a buffer spring, which is disposed between the fixed plate and the elastic rubber head. The multiple limiting slide rods are all slidingly adapted to the sliding holes provided on the fixed plate. The end of the limiting slide rod located on the fixed plate away from the elastic rubber head is provided with a limiting protrusion ring, which is adapted to the fixed plate. The middle part of the elastic rubber head is provided with a sliding opening that is adapted to the tip position of the window-breaking tip.

[0014] The original launching device was primarily designed for double-pane car windows, and this buffer component proved highly effective, especially against sloping or single-pane windows. This technical solution serves two purposes: first, when targeting sloping glass, the elastic rubber head first contacts the surface, creating sliding damping and effectively preventing the window-breaking tip from directly contacting the glass and bouncing off without breaking the window; second, after the window is broken, the elastic rubber head contacts the glass, and the buffer spring causes the window-breaking tip to elastically return to its original position, preventing it from penetrating excessively and injuring people or objects inside the window. Without this buffer component, the launching device could easily penetrate directly into a person facing single-pane glass, causing serious injury.

[0015] Preferably, the launching element is a liquid launching element, which includes a storage chamber and liquid inside the storage chamber. The opening of the storage chamber corresponds to the launching port of the launching tube. When the storage chamber is pushed by the launching piston, the launching piston squeezes the storage chamber, causing the liquid in the storage chamber to be ejected from the opening along the launching port. A corresponding sealing ring is provided between the launching piston and the storage chamber to prevent liquid leakage. This preferred embodiment, through the design of the liquid launching element, achieves the directional spraying of liquids such as fire extinguishing agents or tear gas, expanding the functionality of the device.

[0016] Preferably, the outer end of the launching tube is connected to a second guide head, the second guide head has a launching hole in the middle for liquid launching, the outer side of the launching hole is provided with an outer plug that forms a blocking fit with it, the outer plug is provided with an elastic connecting strip, the elastic connecting strip is connected to the second guide head, when the liquid is launched along the launching hole, the outer plug is impacted and disengaged from the launching hole.

[0017] This preferred solution achieves a leak-proof seal of the firing port by using an outer plug and an elastic connecting strip, and prevents the outer plug from flying out and causing injury. At the same time, the second guide head can be adapted to a flexible pipe to achieve precise spraying into concealed areas.

[0018] Preferably, the launching unit further includes a top position member. The launching tube is composed of an inner tube and an outer tube that are axially movably connected to each other. The inner tube is fixedly connected to the outer shell by a fixed ring. The outer tube is disposed in an annular sliding cavity between the inner tube and the outer shell. The pressure spring, the top position member, and the launching member are sequentially connected and disposed in the inner tube. The top position member is used to limit the compression state of the pressure spring.

[0019] This preferred solution constructs another form of launch triggering structure through the cooperation of the inner tube, outer tube, and top component. The unlocking of the top component is controlled by the sliding of the outer tube, resulting in a compact and reliable structure.

[0020] Preferably, the top positioning component includes a first top positioning body and one or more radial locking pins radially fixed to the outside of the first top positioning body. The inner tube is provided with an L-shaped sliding opening, which is composed of mutually perpendicular X-sliding sections and inner Y-sliding sections. The outer tube is provided with an outer Y-sliding section and a beveled opening. Under normal conditions, the radial locking pin is locked in the X-sliding section. When the outer tube slides along the axial direction of the inner tube, the radial locking pin slides against the beveled opening, thereby causing the radial locking pin to slide from the X-sliding section to the inner Y-sliding section. This allows the radial locking pin to slide out along the axial direction of the inner Y-sliding section and the outer Y-sliding section, and the pressure spring loses the restriction of the top positioning component to control the launching component to fire.

[0021] Preferably, the launching units are multiple, and the stepper motor end of the driving unit is connected to a trigger end. The trigger end has an outwardly protruding active triggering part. The multiple launching units are arranged in a circumferential array and can be detachably fixedly installed in the cylindrical cavity of the outer shell. The cylindrical cavity limits the radial and circumferential rotational degrees of freedom of the corresponding launching unit. Each of the multiple launching units has a passive triggering part, which is arranged in a ring array around the trigger end. The active triggering part and the passive triggering part are mechanically connected to trigger the launching unit. This preferred solution, through the multi-tube array layout and the mechanical transmission cooperation between the active triggering part and the passive triggering part, realizes the sequential independent triggering of multiple launching units, improving operation efficiency.

[0022] Preferably, the active triggering part is an active inclined part fixedly connected to the lower end of the triggering end. The bottom of the active inclined part is provided with a first inclined surface, and the side of the first inclined surface is provided with a buffer inclined surface. The passive triggering part is located at the end of the transmitting unit. The upper end of the passive triggering part is provided with a second inclined surface adapted to the active inclined part. The second inclined surfaces of multiple passive triggering parts are arranged in a circular array. The high point and low point of adjacent second inclined surfaces are close to each other. When the active inclined part rotates, the low point of the second inclined surface of the passive triggering part enters from the buffer inclined surface and fits against the first inclined surface. During the continuous rotation, the first inclined surface relatively moves from low to high and abuts against the high point of the second inclined surface. The pressing of the active inclined part drives the axial sliding of the passive triggering part, thereby controlling the start-up and firing of the transmitting unit.

[0023] Preferably, the active triggering part is a radially protruding structure that is fixedly connected to the radial direction of the triggering end. When the drive motor controls the triggering end to rotate, the active triggering part sequentially actuates the passive triggering part, thereby controlling each transmitting unit to start transmitting in sequence.

[0024] Preferably, the cylindrical cavity is provided with multiple positioning plates arranged along the axial direction of the cylindrical cavity, and the positioning plates are provided with multiple positioning holes for inserting the transmitting unit. This preferred solution, through the setting of positioning plates and positioning holes, achieves precise positioning and stable installation of the transmitting unit within the cylindrical cavity.

[0025] Preferably, the end of the passive triggering part is provided with an abutting cut surface. When the passive triggering part is in its original position, the active triggering part is inserted between two adjacent passive triggering parts. When the drive motor controls the triggering end to rotate, the active triggering part abuts against the abutting cut surface of the passive triggering part when rotating in the forward direction. The active triggering part sequentially moves each passive triggering part, thereby controlling each transmitting unit to start transmitting sequentially.

[0026] Preferably, the end face of the active triggering part is provided with a first sector gear surface, and the end of the passive triggering part is provided with a second sector gear surface that meshes with the first sector gear surface. This preferred solution achieves precise power transmission between the active and passive triggering parts through the meshing transmission of the gear surfaces, thereby improving the reliability of triggering.

[0027] Preferably, the launching unit further includes a launching piston, the launching tube has a launching port at its outer end, the launching piston is disposed inside the launching tube, the launching piston has a locking end at its inner end, the launching piston has a radially protruding annular outer flange at its outer end, and the launching tube has an annular inner flange near the locking end. A pressure spring is fitted between the annular outer flange and the annular inner flange to limit and connect the launching piston. The pressure spring is used to apply an elastic force to the launching element to launch it outward. The locking end has an annular groove in the middle that adapts to the passive triggering part. The passive triggering part has an arc-shaped sheet structure. The passive triggering part and the pressure spring are located on opposite sides of the annular inner flange. The inner end of the passive triggering part is hinged to the end face of the annular inner flange via a first pivot. The passive triggering part is used to limit the axial displacement of the firing piston. Normally, the middle part of the passive triggering part is engaged in an annular groove. When the active triggering part moves the passive triggering part, the passive triggering part flips outward relative to the first pivot and disengages from the annular groove. Under the elastic thrust of the pressure spring, the firing element is propelled outward from the firing port by the firing piston. When the annular outer flange corresponds to a solid firing element, an elastic buffer is provided at the section of the annular outer flange corresponding to the solid firing element. The elastic buffer is made of polyurethane projectile, which is used to avoid the solid firing element from impacting the firing piston and greatly reduces the corresponding noise.

[0028] Preferably, the transmitting unit has multiple units, and the stepper motor of the driving unit is connected to a trigger end. The trigger end has an outwardly protruding active trigger part. The driving unit has multiple driving motors, and each driving motor is matched with an active trigger part. This preferred solution, by setting multiple driving motors, achieves independent control of each transmitting unit and meets the requirement of arbitrarily selecting a transmitting unit.

[0029] Preferably, the launching unit is a single-tube structure, and the control unit adopts a hand-operated mechanical trigger structure, which enables energy storage unlocking and launching actions by manual pressing. This preferred solution provides a single-tube handheld implementation, which is simple and portable, and suitable for single-launch requirements in specific scenarios.

[0030] This invention provides a spring-driven launching device for firefighting, military and police use, which has the following advantages: 1. Multi-unit modular configuration to adapt to complex scenarios and diverse needs: By setting up multiple ring array distribution of launch units, and each launch unit can be detachably and fixedly installed in the outer shell, solid launchers, liquid launchers or smoke launchers can be flexibly installed in different launch units according to actual operation needs. Multiple tasks can be completed in a single deployment without frequent device replacement, which greatly shortens the emergency response time.

[0031] 2. Mechanical drive enables multiple firing modes, significantly improving operational efficiency and flexibility: The control unit drives the stepper motor to rotate the trigger end, and the active trigger part sequentially activates the passive trigger part of each firing unit, enabling each firing unit to start independently in sequence. Multiple firing modes such as single shot, burst fire, and volley fire can be flexibly switched according to the needs of the scenario, significantly improving operational efficiency.

[0032] 3. Spring-powered design significantly improves safety and reliability: Each launching unit uses a pressure spring as the launching power, completely abandoning the traditional gunpowder ignition and high-pressure gas cylinder driving mode, thus avoiding safety risks at the source; at the same time, through the locking cooperation between the passive trigger and the annular groove of the launching piston, the launching unit is normally locked, effectively preventing accidental launch and improving the safety of carrying, storing and using the device.

[0033] 4. Compact and portable structure, easy disassembly and replacement: Multiple launch units are arranged in a circumferential array within the cylindrical cavity of the outer shell. With the limiting design of positioning plates and positioning holes, the overall structure is compact while realizing the multi-tube launch function. The launch units are detachable, allowing operators to quickly disassemble, replace and reinstall them, making them suitable for rapid on-site operations.

[0034] 5. Optimized launcher compatibility, improved launch stability and operational coverage: Dedicated guidance structures and limiting components are designed for different types of launchers to ensure the launch stability of solid launchers; liquid launchers are equipped with a second guide head with an elastic connecting plug to achieve leak-proof sealing of the launch port, and the second guide head can be adapted to flexible / rigid delivery pipelines, guiding fire extinguishing agents, tear gas, etc. to areas that are difficult to directly access, such as inside the equipment, interlayers, and dead corners, to achieve precise point spraying.

[0035] 6. Intelligent control and monitoring enhance ease of use and battery life: An integrated control unit, along with a main power switch, drive switch, voltage display, and laser aiming device, enables centralized on / off control, real-time power monitoring, and precise launch positioning, making it easy to use and providing strong battery life assurance.

[0053] The following is in conjunction with the appendix Figure 1-21 The present invention will be further described with reference to Examples 1-5.

[0054] This invention can be specifically divided into multi-tube launching devices and single-tube launching devices. The multi-tube launching device refers to a structure with multiple launching units, which is further divided into Embodiment 1, Embodiment 2, and Embodiment 3 (which can be assembled with a drone) based on different housing mounting components. The multi-tube launching device can also be divided into rotary and push-button types based on the different transmission methods of the drive unit and the launching unit. The rotary type includes paddle rotation transmission and gear rotation transmission. Furthermore, the launching unit can be a solid launching element, a liquid launching element, or a smoke launching element, depending on the launching component it emits.

[0055] The multi-tube launcher is divided into Embodiment 1, Embodiment 2, and Embodiment 3, which can be assembled with a UAV, according to the different outer casing mounting components, as follows: Embodiment 1 like Figures 1 to 6 As shown, this embodiment provides a spring-driven launching device for firefighting, military, and police use, which constitutes the smallest working unit of the technical solution of this invention. The device includes a control unit, a drive unit, a housing, and one or more launching units. The housing serves as the supporting foundation for the entire device, and its interior forms spaces for installing various functional components. The launching unit is the core component that performs the launching action, and it includes a launching tube 12, a pressure spring 14, and a launching element.

[0056] Specifically, the launch tube 12 constitutes the main structure of the launch unit, and its hollow interior forms a cavity for accommodating the pressure spring 14 and the launcher. The pressure spring 14 is built into the launch tube 12, and its function is to provide a power source for the launch action. In this embodiment, the energy storage method of the pressure spring 14 has several implementation forms. In a preferred embodiment, the pressure spring 14 can be configured in a compressed state, and is compressed axially by an external force, thereby converting mechanical energy into elastic potential energy for storage; in another feasible embodiment, the pressure spring 14 can also be configured in a torsional state, and torsional elastic potential energy is stored by torturing the spring body.

[0057] The launcher is installed inside the launch tube 12, and its specific form can be flexibly changed according to actual operational needs. For example, the launcher can be a solid projectile for demolition, a liquid container for fire extinguishing or dispersal, or a smoke generator for smoke warning. Under normal conditions, the launcher is located in a preset position inside the launch tube 12 and is kept stationary by the preload of the pressure spring 14 or the locking mechanism. When the device receives a launch command, the drive unit actuates, releasing the restriction on the pressure spring 14. The potential energy stored in the pressure spring 14 is released instantaneously and converted into the kinetic energy of the launcher, thereby propelling the launcher out of the launch tube 12 at high speed, completing the launch action.

[0058] The driving unit provides the power or control signal required to trigger the launch action. In this embodiment, the driving unit employs either a motor-driven or mechanical-driven approach. Specifically, the motor-driven approach can use a stepper motor or a servo motor, whose rotational motion drives the transmission mechanism, thereby triggering the launch unit's unlocking action. The mechanical-driven approach can use purely mechanical structures such as manual pressing, lever transmission, or cable transmission, allowing for launch triggering through manual operation. It should be understood that although the specific transmission details of the driving unit are not elaborated in this embodiment, whether a motor-driven or mechanical-driven approach is used, as long as the function of controlling the release of potential energy of the launch unit can be achieved, it should fall within the protection scope of this invention. This higher-level concept allows the technical solution of this invention to cover various product forms, from handheld simple devices to UAV-mounted automated devices, greatly expanding the applicable scenarios of the device.

[0059] Furthermore, the control unit includes a control circuit board 5, a battery assembly 6, a switch assembly, and a display assembly 7 that are electrically connected to each other. The drive unit is a stepper motor. The housing includes a control end cover 26 and a tube body 27 that are plugged into each other. The control end cover 26 has a control chamber for accommodating the control circuit board 5, the battery assembly 6, and the drive unit. The stepper motor is fixedly mounted on a mounting plate 8 in the control chamber. The rotating shaft of the stepper motor passes through a through hole in the mounting plate 8 and connects to the transmitting unit for controlling the triggering of the transmitting unit. In this embodiment, the housing adopts a split plug-in structure. The control end cover 26 and the tube body 27 can be connected by snaps, threads, or tight fit. This split design facilitates the assembly and maintenance of internal components. When the internal circuit malfunctions or the battery needs to be replaced, only the control end cover 26 needs to be separated for operation. The control circuit board 5, as the core control hub, integrates a microprocessor and drive circuit for receiving external commands and controlling the movement of the stepper motor. The battery assembly 6 is preferably a rechargeable lithium battery pack, which is connected to the control circuit board 5 through wires to provide power to the entire device. Mounting plate 8 serves as the supporting base for the drive unit and is fixed within the control chamber. Through holes on it allow the stepper motor shaft to pass through. The trigger end 2, connected to the end of the shaft, triggers the locking mechanism of the launching unit during rotation, thus achieving the launching action. The selection of a stepper motor allows for precise control of the rotation angle, enabling sequential or point-to-point triggering of the multi-tube launching units. The control end cover 26 and the tube body 27 are mutually engaged via a snap-fit ​​assembly. The mounting plate 8 has axial threaded holes corresponding to the launching units, with threaded push rods 46 threaded into these holes. The outer end of the threaded push rod 46 abuts against the end of the launching unit, thereby limiting the axial freedom of the launching unit.

[0060] Regarding the specific connection relationship of the control circuit, the switch assembly includes a main power switch 9 and a drive switch 10. The drive switch 10 is connected to the control circuit board 5 and the stepper motor, respectively. The drive switch 10 is used to control the start and stop of the stepper motor. A display assembly 7 and the main power switch 9 are set at the end of the housing. The display assembly 7 includes a voltage display. The housing is equipped with a laser sight 11. The main power switch 9 is connected to the battery assembly 6, the drive switch 10, the laser sight 11, and the voltage display, respectively. The main power switch 9 is used to control the connection and start / stop of the battery assembly 6 with other components. The voltage display is located at the outer end of the housing. When the main power switch 9 is activated, the battery assembly 6 supplies power to the drive switch 10, the laser sight 11, and the voltage display. At this time, the drive switch 10 can start controlling the drive motor 1, the laser sight 11 emits the corresponding aiming laser, and the voltage display shows the current voltage of the battery assembly 6 to prevent the battery assembly 6 from running out of power. This circuit layout design greatly improves the convenience and safety of the device. As the main control switch, the main power switch 9 can cut off or connect the power of the entire system with one click, preventing accidental activation during transportation or when not in operation. The voltage display allows operators to intuitively read the current battery voltage, thereby determining whether the remaining power meets operational requirements and avoiding the risk of launch failure due to depleted power. The laser sight 11 is used to emit a visible laser beam, assisting the operator in aiming at the target and improving launch accuracy. In one specific embodiment, the laser sight 11 can be mounted on the upper part of the housing, in which case the operator's line of sight coincides with the aiming line, facilitating handheld aiming. In Embodiment 1, the laser sight 11 is located on the upper part of the housing, and the laser sight 11 is detachably connected to the housing. Furthermore, a charging port 49 for connecting the battery assembly 6 is provided at the end of the housing for external charging.

[0061] Example 2: Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 lies in only two points. First, the location of the laser sight 11: in Embodiment 2, the laser sight 11 is located at the lower end of the housing. The laser sight 11 can also be installed at the lower end of the housing to accommodate different gripping habits or avoid interference from other components. The drive switch 10 directly controls the action of the stepper motor. After pressing the drive switch 10, the stepper motor rotates according to a preset program, driving the trigger end 2 to actuate and complete the firing. Second, Embodiment 2 uses a lever-like pressing method, while Embodiment 1 uses a button pressing method.

[0062] Example 3: As Figure 8As shown, Embodiment 3, compared to Embodiment 1, removes the pressing method of the laser sight 11 and the switch assembly, or the tossing method of Embodiment 2. Instead, it directly uses a bracket mounting slot at the lower end of the outer casing. This bracket mounting slot detachably mounts a drone mounting bracket 48 for fixing to the drone. The electrical components in Embodiment 3 include a wireless signal receiver, which transmits signals to the control circuit board 5. The control circuit board 5 drives the transmitting unit via a stepper motor, allowing the user to control it wirelessly. Embodiment 3 is used to mount on a fire-fighting drone to remotely launch breaching projectiles at distances of over ten meters to break down tempered glass, curtain walls, laminated glass, and single / double-layer tempered glass windows, facilitating rapid smoke extraction and fire extinguishing. Since this embodiment and other embodiments have multiple launchers available, different launchers can be installed for different situations. For example, a solid window-breaking launcher can be launched first to break the window, followed by the launch of a large-capacity liquid fire extinguishing agent to extinguish the fire, thus achieving a synergistic effect of breaking the window and extinguishing the fire.

[0063] Multi-tube launching devices can be further divided into rotary and push-button types based on the different transmission methods of the drive unit and launching unit, as detailed below: The launching unit of the multi-tube rotary launching device is a multi-tube structure arranged in a circumferential ring array. The stepper motor of the driving unit is connected to a trigger end 2. The trigger end 2 is provided with an outwardly protruding active trigger part 3. The multiple launching units are arranged in a circumferential array and can be detachably fixed in a cylindrical cavity of the outer shell. The cylindrical cavity limits the radial and circumferential rotational degrees of freedom of the corresponding launching unit. Each of the multiple launching units is provided with a passive trigger part 4. The passive trigger parts 4 of the multiple launching units are arranged in a ring array with the trigger end 2 as the center. The active trigger part 3 and the passive trigger part 4 are mechanically connected to trigger the launching unit to start.

[0064] Multi-tube rotary launching devices include those with a lever-driven rotary transmission and those with a gear-driven rotary transmission. For example... Figure 9 As shown, the specific structure of the rotary transmission method is as follows: The active triggering part 3 is a radially protruding structure fixedly connected to the triggering end 2. When the drive motor 1 controls the triggering end 2 to rotate, the active triggering part 3 sequentially actuates the passive triggering parts 4, thereby controlling each launching unit to start launching sequentially. Gear transmission rotary type: The end of the passive triggering part 4 is provided with an abutting surface. When the passive triggering part 4 is in its original position, the active triggering part 3 is inserted between two adjacent passive triggering parts 4. When the drive motor 1 controls the triggering end 2 to rotate, the active triggering part 3 abuts against the abutting surface of the passive triggering part 4 when rotating in the forward direction, and the active triggering part 3 sequentially actuates each passive triggering part 4, thereby controlling each launching unit to start launching sequentially. Figure 10As shown, the end face of the active triggering part 3 is provided with a first sector gear surface 33, and the end of the passive triggering part 4 is provided with a second sector gear surface 34 that meshes with the first sector gear surface 33.

[0065] like Figure 11 As shown, the specific structure of the launching unit of the multi-tube rotary launching device is as follows: The launching unit further includes a launching piston 13, a launching port 15 is provided at the outer end of the launching tube 12, the launching piston 13 is disposed inside the launching tube 12, the inner end of the launching piston 13 is provided with a locking end, the outer end of the launching piston 13 is provided with a radially protruding annular outer flange 16, an annular inner flange 17 is provided inside the launching tube 12 near the locking end, a pressure spring 14 is fitted between the annular outer flange 16 and the annular inner flange 17 to limit and connect the launching piston 13, the pressure spring 14 is used to apply an outward elastic force to the launching component, and the locking end is provided with an adapter passive in the middle. The passive triggering part 4 has an annular groove 18. The passive triggering part 4 has an arc-shaped plate structure. The passive triggering part 4 and the pressure spring 14 are respectively located on both sides of the annular inner flange 17. The inner end of the passive triggering part 4 is hinged to the end face of the annular inner flange 17 through a first pivot. The passive triggering part 4 is used to limit the axial displacement of the firing piston 13. Under normal conditions, the middle part of the passive triggering part 4 is locked in the annular groove 18. When the active triggering part 3 moves the passive triggering part 4, the passive triggering part 4 flips outward relative to the first pivot and disengages from the annular groove 18. Under the elastic thrust of the pressure spring 14, the firing element is pushed outward from the firing port 15 by the firing piston 13. When the annular outer flange 16 corresponds to the solid firing element, the section of the annular outer flange 16 corresponding to the solid firing element is provided with an elastic buffer. The elastic buffer is made of polyurethane projectile. The polyurethane projectile is used to avoid the hard impact of the solid firing element on the firing piston 13 and greatly reduce the corresponding noise generation.

[0066] like Figure 11-15 As shown, the emitter can be a solid emitter, a liquid emitter, or a smoke emitter. This invention features multiple emitter units arranged in a circumferential ring array, each of which can be filled with different emitters to meet various complex environmental requirements.

[0067] like Figure 11-14As shown, the launching device is a solid-state launching device, specifically a window-breaking tip 19. The outer end of the launching tube 12 is connected to a first guide head 20, which has a guide channel adapted to the outer diameter of the window-breaking tip 19. The end of the window-breaking tip 19 is equipped with a long tungsten carbide cone for better window-breaking effect. The first guide head 20 may also contain multiple circumferentially elastic locking components. Each elastic locking component includes a pressure screw, a compression spring, and a circular steel ball connected in sequence. The radial thread of the pressure screw is adapted to a radial threaded hole in the first guide head 20. The inner end of the pressure screw is connected to the compression spring. The circular steel ball, under the elastic force of the compression spring, abuts against the surface of the window-breaking tip 19, thus limiting the movement of the window-breaking tip 19. The user can control the pressure locking of the circular steel ball on the window-breaking tip 19 by adjusting the rotation of the pressure screw. Figure 11-12 As shown, the surface of the window-breaking tip 19 is provided with a guide spiral groove 191, which is adapted to a circular steel ball or guide protrusion inside the launch tube 12. During the launch of the window-breaking tip 19, the mutual adaptation between the guide spiral groove 191 and the circular steel ball or guide protrusion significantly improves the accuracy of the window-breaking tip 19. The device employs an energy storage mechanism for pre-tensioning and charging, driving the projectile to fly out at high speed upon launch. The projectile adopts a spiral stabilization design, ensuring stable flight attitude and precise impact. It achieves impact shattering and penetration of glass and metal plates through high-kinetic-energy rigid impact. The four-shot structure can continuously output four impact energies, significantly improving the success rate of breaching high-strength, high-thickness protective structures.

[0068] like Figure 14 As shown, the end of the window-breaking tip rod 19 is provided with a buffer assembly. The buffer assembly includes a fixed plate 28, an elastic rubber head 29, and multiple limiting slide rods 30. The fixed plate 28 is fixedly connected to the window-breaking tip rod 19. The multiple limiting slide rods 30 are all connected to the fixed plate 28 and the elastic rubber head 29. The multiple limiting slide rods 30 are arranged in a circular array with the window-breaking tip rod 19 as the center. Each of the multiple limiting slide rods 30 is sleeved with a buffer spring 31. The buffer spring 31 is disposed between the fixed plate 28 and the elastic rubber head 29. The multiple limiting slide rods 30 are all slidingly adapted to the sliding holes provided in the fixed plate 28. The end of the limiting slide rod 30 located on the fixed plate 28 away from the elastic rubber head 29 is provided with a limiting protrusion ring 32. The limiting protrusion ring 32 is adapted to the fixed plate 28. The middle part of the elastic rubber head 29 is provided with a sliding opening adapted to the tip position of the window-breaking tip rod 19.

[0069] like Figure 15As shown, the launching device is a liquid launching device, which includes a storage chamber 21 and liquid inside the storage chamber 21. The opening of the storage chamber 21 corresponds to the launching port 15 of the launching tube 12. When the storage chamber 21 is pushed by the launching piston 13, the launching piston 13 squeezes the storage chamber 21, thereby causing the liquid in the storage chamber 21 to be sprayed out from the opening along the launching port 15. The outer end of the launching tube 12 is connected to a second guide head 22. The second guide head 22 has a launching hole for liquid launching in the middle. An outer plug 23 is provided on the outside of the launching hole to form a blocking fit with it. The outer plug 23 has an elastic connecting strip 24, which is connected to the second guide head 22. When the liquid is launched along the launching hole, the outer plug 23 is impacted and disengaged from the launching hole. The launched liquid can be tear gas or fire extinguishing agent. This tear gas or fire extinguishing agent complies with legal fire protection regulations and meets fire protection requirements. The elastic connecting strip 24 can effectively limit the outer plug 23, preventing it from being ejected upon impact and causing injury to the face or eyes. The outer plug 23 is a rubber stopper that tightly seals the firing port through an interference fit. Under normal conditions, the seal is firm and not easily detached, effectively preventing leakage of extinguishing agent or internal media, and ensuring safe and reliable carrying and transportation.

[0070] Example 4: Press-type multi-tube launcher, such as Figure 16-21 As shown, the launching unit also includes a top-positioning component. The launching tube 12 consists of an inner tube 35 and an outer tube 36 that are axially movably connected to each other. The inner tube 35 is fixedly connected to the outer shell by a fixing ring. The outer tube 36 is disposed in an annular sliding cavity between the inner tube 35 and the outer shell. The pressure spring 14, the top-positioning component, and the launching component are sequentially connected and disposed within the inner tube 35. The top-positioning component includes a first top-positioning body 37 and one or more radially fixed radial locking pins 38 outside the first top-positioning body 37. The inner tube 35 is provided with an L-shaped sliding opening. The opening is composed of mutually perpendicular X-slide section 39 and inner Y-slide section 40. The outer tube 36 is provided with outer Y-slide section 41 and inclined opening 42. Under normal conditions, the radial locking pin 38 is locked in the X-slide section 39. When the outer tube 36 slides along the axial direction of the inner tube 35, the radial locking pin 38 slides against the inclined surface of the inclined opening 42, thereby causing the radial locking pin 38 to slide from the X-slide section 39 into the inner Y-slide section 40. This causes the radial locking pin 38 to slide out along the axial direction of the inner Y-slide section 40 and the outer Y-slide section 41, and the pressure spring 14 loses the restriction of the top position member to control the launching member to fire.

[0071] like Figure 16-18As shown, the active triggering part 3 is an active inclined part 43 fixedly connected to the lower end of the triggering end 2. The bottom of the active inclined part 43 is provided with a first inclined surface 44, and the side of the first inclined surface 44 is provided with a buffer inclined surface 45. The passive triggering part 4 is located at the end of the transmitting unit. The upper end of the passive triggering part 4 is provided with a second inclined surface 47 adapted to the active inclined part 43. The second inclined surfaces 47 of multiple passive triggering parts 4 are arranged in a ring array. The high and low points of adjacent second inclined surfaces 47 are close to each other. When the active inclined part 43 rotates, the lower part of the second inclined surface 47 of the passive triggering part 4 enters and fits against the first inclined surface 44 through the buffer inclined surface 45. During the continuous rotation, the first inclined surface 44 relatively abuts against the higher part of the second inclined surface 47 from low to high. The pressing of the active inclined part 43 drives the axial sliding of the passive triggering part 4, thereby controlling the start-up and firing of the transmitting unit. The overall arrangement of each passive inclined surface is similar to that of a fan blade.

[0072] Example 5: A transmitting device with multiple tubes and multiple drive motors 1. The transmitting units are arranged in a circumferential ring array of multiple tubes. Each drive unit has a stepper motor end connected to a trigger terminal 2. The trigger terminal 2 has an outwardly protruding active triggering part 3. Each drive unit has multiple drive motors 1, and each drive motor 1 corresponds to and is adapted to one active triggering part 3. This technical solution is used when multiple drive motors 1 individually control their corresponding transmitting units, thereby fulfilling the requirement of controlling the transmission of any transmitting unit.
