The gas generating tank is used to launch window-breaking projectiles.

[0007] According to the technical solution provided in this application, a gas transition section is also formed inside the connecting cylinder. The gas transition section is located between the first connecting section and the second connecting section. The diameter of the port of the gas transition section near the gas generating tank is smaller than that of the port near the launching cylinder.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1 Please refer to Figure 1 and Figure 2 The schematic diagram and cross-sectional view of the multi-shot window-breaking device provided in this embodiment are shown. This multi-shot window-breaking device is used in conjunction with a drone to break target windows. Specifically, the multi-shot window-breaking device includes: The main housing 7 with a broken window is used for mounting drone equipment at its top. Window breaking assembly 2 is used to fire window breaking projectiles 3 at a target window. Window breaking assembly 2 includes: multiple launch tubes 8 arranged in an array; each launch tube 8 is engaged with the main window breaking housing 7, and the launch tube 8 is equipped with a window breaking projectile 3. The launch tube 8 is used to limit the launch path of the window breaking projectile 3. The control component is connected to the window-breaking component 2 and the UAV equipment via signal communication, and is used to cooperate with the UAV equipment to control the window-breaking component 2 to fire the window-breaking projectile 3 at the target window.

[0026] In this embodiment, the multi-shot window-breaking device is often mounted on unmanned aerial vehicle (UAV) equipment. For example, in a high-rise fire, the UAV equipment can carry the multi-shot window-breaking device to the target window that needs to be broken, helping rescuers speed up the rescue operation. The multi-shot window-breaking device includes a main window-breaking housing 7, which is used to carry the window-breaking projectile 3 and to perform the task of being mounted on the UAV equipment; the window-breaking component 2 is used to launch the window-breaking projectile 3, which is the main component used to break the window. The window-breaking projectile 3 is fluid-shaped, making it more suitable for performing flight-based missions.

[0027] To accelerate the window breaking efficiency, the window breaking component 2 includes multiple launch tubes 8 arranged at intervals along the horizontal direction, and each launch tube 8 contains a window breaking projectile 3. Thus, the UAV equipment equipped with this window breaking device can actually launch multiple projectiles. Furthermore, in order to accelerate the assembly speed of the launch tubes 8 and the main window breaking housing 7, in this embodiment of the application, the launch tubes 8 are all snap-fitted to the main window breaking housing 7 to quickly complete the assembly of the launch tubes 8.

[0028] The control component is the control unit of the multi-shot window-breaking device. It can be integrated into the main control system of the UAV equipment or connected to the main control system of the UAV equipment via signal communication. There are no special restrictions on its setting here. The control component can be a high-performance, low-power embedded processor that can quickly determine the position of the target window and control the window-breaking component 2 to fire the window-breaking bullet 3. For an introduction to the control component, please refer to the current conventional image and signal processing technologies, etc., which will not be elaborated on here.

[0029] In a preferred embodiment, see Figure 7 The main housing 7 of the window breaking device has a plurality of window breaking projectile fixing positions 71 arranged in a row, and the number of window breaking projectile fixing positions 71 corresponds to the number of launching tubes 8; The bottom of the main shell 7 of the window breaking device is provided with a snap-fit ​​hole 4, which is connected to the fixing position 71 of each window breaking bullet. The snap-fit ​​hole 4 is used in conjunction with the fixing pin 9 to snap the launching tube 8.

[0030] Specifically, the window-breaking projectile fixing position 71 is a through-hole structure opened on the main window-breaking housing 7 (in order to fix the connecting cylinder 1, the window-breaking projectile fixing position 71 on the side of the main window-breaking housing 7 away from the launching cylinder 8 has a certain extension baffle 72), the specific extension direction is shown in [reference]. Figure 1 As shown, the window-breaking projectile fixing position 71 is set to correspond to the number of launch tubes 8 that can be installed; a snap-fit ​​hole 4 is provided at the bottom of the window-breaking main housing 7, which allows the fixing pin 9 to extend into the window-breaking main housing 7, thereby completing the snap-fit ​​of the launch tube 8; it should be noted that since the window-breaking main housing 7 has a certain thickness, multiple threads can be provided in the snap-fit ​​hole 4 so that the fixing pin 9 and the snap-fit ​​hole 4 are threadedly connected, so that the fixing pin 9 has a certain connection strength, thereby more reliably completing the snap-fit ​​of the launch tube 8.

[0031] In a preferred embodiment, see Figure 2 , Figure 5 and Figure 6 The broken window component 2 also includes: The connecting cylinder 1 has a circumferentially circumferentially formed engagement groove 11 on its outer side. The engagement groove 11 is matched with the fixing pin 9 and is correspondingly set with the engagement hole 4. The engagement groove 11 and the fixing pin 9 can fix the connecting cylinder 1 in the window break spring fixing position 71. The connecting cylinder 1 is hollow inside and forms a first connecting section 12 and a second connecting section 13 respectively. The launching tube 8 is threadedly connected to the first connecting section 12 and communicates with the inside of the connecting tube 1; the second connecting section 13 is equipped with a gas generating tank 5, which is used to launch the window-breaking projectile 3.

[0032] Specifically, the connecting cylinder 1 is the main component for installing the launch tube 8 and the gas generator 5. The connecting cylinder 1 has a locking groove 11 on its circumference. After the connecting cylinder 1 is inserted into the window-breaking bullet fixing position 71, the fixing pin 9 can be screwed into the locking hole 4 and extended into the locking groove 11 to abut against the locking groove 11, thereby realizing the quick installation of the connecting cylinder 1. In addition, one end of the connecting cylinder 1 is partially threaded to the launch tube 8 (i.e., the first connecting section 12 is threaded to the launch tube 8). At the rear of the connecting cylinder 1, there is also a gas generator 5 or a gas generator for launching the window-breaking bullet 3 inside the launch tube 8. The launch tube 8 is connected to the connecting cylinder 1, so the gas generator 5 located inside the connecting cylinder 1 can use the powerful air pressure triggered by instantaneous triggering to control the window-breaking bullet 3 to fly towards the target window.

[0033] In a preferred embodiment, see Figure 5 and Figure 6 A gas transition section 14 is also formed inside the connecting cylinder 1. The gas transition section 14 is located between the first connecting section 12 and the second connecting section 13. The diameter of the port of the gas transition section 14 near the gas generating tank 5 is smaller than that of the port near the launching cylinder 8.

[0034] Since a gas generating tank 5 is used in this embodiment, a gas transition section 14 is also provided in the connecting tube 1 between the launching tube 8 and the gas generating tank 5. The gas transition section 14 adopts a variable diameter structure design, which can separate the first connecting section 12 and the second connecting section 13, so that the gas generating tank 5 and the launching tube 8 can be quickly positioned. On the other hand, the diameter of the port of the gas transition section 14 near the gas generating tank 5 is smaller than that of the port near the launching tube 8, so that the gas emitted by the gas generating tank 5 can be stored in the gas transition section 14, which makes it easier to launch the window-breaking projectile 3. In the actual design process, the structure of the gas transition section 14 can be seen in the figure. The specific design parameters need to be combined with the specifications of the gas generating tank 5 and the launching tube 8, and no special limitation is made here.

[0035] In a preferred embodiment, see Figure 2 and Figure 5 A fixing ring 10 is also provided at the port of the gas generating tank 5 away from the launching tube 8. The fixing ring 10 is threaded to the outside of the gas generating tank 5. The fixing ring 10 is located inside the second connecting section 13 and is threaded to the second connecting section 13 of the connecting tube 1. Specifically, to ensure that the gas generating tank 5 is fixed in the connecting cylinder 1, a fixing ring 10 is provided at the port of the gas generating tank 5 away from the launching cylinder 8. The fixing ring 10 is connected to the end of the gas generating tank 5 away from the launching cylinder 8, and because it is a ring structure, it will not obstruct the plug-in wiring harness at the tail of the gas generating tank 5. Since the fixing ring 10 is connected to the outside of the gas generating tank 5, and the outside of the fixing ring 10 is also provided with a thread that matches the inside of the second connecting section 13, the two can be connected by the thread. Since the fixing ring 10 needs to be screwed into the connecting cylinder 1, for ease of operation, an operating hole 15 is also provided on the side of the fixing ring 10 near the opening of the connecting cylinder 1. The design of the operating hole 15 makes it easy for technicians to use tools to tighten the fixing ring 10 into the connecting cylinder 1, while also ensuring the connection stability of the gas generating tank 5.

[0036] In a preferred embodiment, see Figure 5 A limiting port 18 is provided on the outer wall of the connecting cylinder 1 near the second connecting section 13. After the connecting cylinder 1 is placed in the window break spring fixing position 71, the limiting port 18 can be engaged with the snap-fit ​​piece pre-set on the back of the window break main housing 7.

[0037] Specifically, a limiting port 18 is provided on the outside of the connecting cylinder 1. The limiting port 18 can be a notch opened on the outer edge of the connecting cylinder 1, so that when positioning the connecting cylinder 1, it is not necessary to blindly connect the limiting port 18 with the snap-fit ​​component. The design of the limiting port 18 and the snap-fit ​​component can increase the connection stability of the connecting cylinder 1 on the one hand, and can also quickly locate the assembly direction of the connecting cylinder 1 on the other hand, and can also assist technicians in installation error correction. The snap-fit ​​component here can be a snap-fit ​​pin or other structure, and no specific characteristics are limited here.

[0038] In a preferred embodiment, the multi-window-breaking device further includes: a mounting frame 6; The mounting frame 6 has an extension plate extending to the outside of the main housing 7 of the broken window, and the extension plate has a connection hole 61; the connection hole 61 cooperates with the external connector for connection with the drone equipment.

[0039] Specifically, the mounting frame 6 is a structural component for mounting the drone equipment, and the structure of the mounting frame 6 is as follows: Figure 1 As shown, the design of the mounting frame 6 ensures that the window-breaking device is not damaged during frequent mounting with drone equipment.

[0040] In a preferred embodiment, see Figure 4 The control assembly includes multiple electronic controllers 17, each of which is connected to a different gas generating tank 5. The electronic controller 17 is used to activate the gas generating tank 5 to launch the window-breaking bullet 3 inside the corresponding launch tube 8.

[0041] Specifically, when a window-breaking task needs to be performed, the control component outputs a PWM signal to the electronic controller 17, which converts the PWM signal into an electrical signal to control the activation of the gas generator. In this embodiment, multiple electronic controllers 17 are used, and each electronic controller 17 can control the activation of a gas generator 5, thereby achieving flexible control of launching the corresponding window-breaking projectile 3 as needed according to the actual situation on site.

[0042] In addition, the multi-window breaking device also includes: a sensing component 16; the sensing component 16 includes at least: a laser rangefinder, which is used to collect the distance between the emission port of the emission tube 8 and the target window and generate a corresponding distance signal.

[0043] Specifically, to prevent the window-breaking projectile 3 from failing to break the window due to launch distance issues, a laser rangefinder is provided in this embodiment. The laser rangefinder can accurately monitor the position of the front port (launch port) of the launch tube 8 and the target window, providing guidance for the launch of the window-breaking projectile 3. At the same time, through the connection between the control component and the UAV equipment, the data signal can be directly fed back to the overall control system of the UAV equipment to control the UAV to adjust its attitude. Meanwhile, the sensing component 16 can also include a visible light camera and an infrared sensor. The visible light camera is used to collect the external environment and provide image or video information for the movement of the UAV equipment. The infrared sensor can sense both the human body and heat sources. In conjunction with the fire scene rescue mentioned above, the infrared sensor, based on the visible light camera guiding the UAV equipment to the area where the target window is located, can also quickly lock the specific target window position, i.e., the window closest to the fire source, by sensing the heat source. Based on the above description and in combination Figures 1-7 As can be seen, this application proposes a multi-window-breaking device, the specific working principle of which is as follows: Before mounting, the gas generator 5 needs to be fixedly connected to the connecting cylinder 1 under the action of the fixing ring 10. Then, the connecting cylinder 1 is placed into the window-breaking projectile fixing position 71, and the connecting cylinder 1 and the window-breaking main housing 7 are quickly locked together using the fixing pin 9. Then, the launching tube 8 can be screwed into the connecting cylinder 1, and the window-breaking projectile 3 can be placed into the launching tube 8, completing the accurate work before mounting. Next, the mounting frame 6 is connected to the UAV equipment, while ensuring that the control components and the control system of the UAV equipment are in communication connection, so that the corresponding window-breaking task can be performed afterward.

[0044] Assuming the current situation is a fire rescue scenario, the drone can use its GPS system and various sensors in the sensing component 16 to locate the fire site. At the same time, the control component controls the drone to move towards the fire site. After reaching the floor where the fire is located, it can use the infrared sensor to detect the heat source and lock onto the target window (the window closest to the fire source). Finally, after the laser rangefinder indicates that the target launch position has been reached, the electronic controller 17 activates the corresponding gas generator 5, causing the gas generator 5 to launch the window-breaking projectile 3 to break the target window.

[0045] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
