Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a window-breaking mechanism for UAVs. Background Technology
[0002] As a new industrial technology, drones have been widely used in various fields. In China, many fire departments have successfully used drones for fire scene reconnaissance and monitoring, and dropping rescue supplies, with very obvious results. With in-depth research on drone accessories, drones have expanded from traditional working methods to specialized working modes that carry functional accessories.
[0003] During fire rescue operations, drones are typically used to deploy window-breaking mechanisms to high altitudes to break windows. However, current window-breaking mechanisms can only fire a single breaking head at a time. When encountering windows that are relatively sturdy or have multiple layers of glass, the windows may not be completely broken, requiring repeated operations and affecting rescue time.
[0004] Therefore, we propose a window-breaking mechanism for drones to address the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to solve the aforementioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a window-breaking mechanism for unmanned aerial vehicles (UAVs), comprising a mounting plate installed below the UAV, a window-breaking cylinder mounted on the bottom of the mounting plate via a mounting bracket, a storage box fixed to the top of the window-breaking cylinder penetrating the mounting plate, the interior of the window-breaking cylinder being divided into a drive chamber and a launch chamber, a drive rod extending into the launch chamber being slidably mounted along the length direction inside the drive chamber, and a drive plate located inside the drive chamber being fixed on the drive rod, elastic drive members being provided on the drive plate and the inner end wall of the drive chamber, a connecting member being fixed to the top of the drive plate, and a toothed rod being fixed to the top of the connecting member extending to the outside of the window-breaking cylinder, and a drive structure cooperating with the toothed rod being mounted on the mounting plate.
[0007] Furthermore, the drive structure includes a drive motor mounted above the mounting plate, and the output end of the drive motor is fixed with an incomplete gear that engages with a rack and pinion.
[0008] Furthermore: the outer surface of the upper part of the window-breaking cylinder is symmetrically fixed with parallel limiting rods, and guide rods are fixed along the length direction on the opposite side of the two limiting rods respectively. The side of the toothed rod is provided with a guide groove that cooperates with the guide rod.
[0009] Furthermore: a sealing cover is installed at the opening on the top of the storage box, and mounting seats are respectively installed on the side of the sealing cover and the side of the storage box, and the two mounting seats are connected by locking bolts.
[0010] Furthermore, the sealing cover has an inwardly recessed groove inside, and several compression springs are fixed at equal intervals inside the groove, with the same pressure plate installed at the bottom of the multiple compression springs.
[0011] Furthermore: fixed mounting bases are symmetrically fixed on both sides of the mounting plate, and a movable mounting base is provided on one side of each fixed mounting base. The fixed mounting base and the movable mounting base are connected by fixing bolts.
[0012] The beneficial effects of this utility model are:
[0013] This invention features a storage box and a drive structure installed at both ends of the window-breaking cylinder. The drive structure repeatedly drives the toothed rod to retract and release. The toothed rod, through the connecting piece and the drive plate, drives the drive rod to move repeatedly, enabling continuous firing of the breaking head in the storage box to break the window. This avoids incomplete window breaking, shortens the window breaking time, and allows for timely rescue. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] A window-breaking mechanism for unmanned aerial vehicles (UAVs are already known prior art and will not be described in detail here). Specifically, fixed mounting seats 18 with upward inclination are symmetrically fixed on both sides of the mounting plate 1, and a movable mounting seat 19 is fitted on one side of the fixed mounting seat 18. When the fixed mounting seat 18 and the movable mounting seat 19 are fitted onto the support leg of the UAV, the fixing bolt passes through the movable mounting seat 19 and is threadedly connected to the fixed mounting seat 18, thereby achieving a fastening effect and preventing the fixed and movable mounting seats 18 and the movable mounting seat 19 from loosening during use, thus having strong stability.
[0023] The bottom of the mounting plate 1 is symmetrically fixed with mounting brackets 2, and the two mounting brackets 2 are connected to the same window breaking cylinder 3, thereby securing the window breaking cylinder 3. In detail, the window breaking cylinder 3 is divided into a driving chamber 301 and a launching chamber 302. A storage box 4 is fixed on the upper part of the window breaking cylinder 3, and the bottom of the storage box 4 is connected to the interior of the launching chamber 302. The storage box 4 is used to store the breaking head a.
[0024] A drive rod 5 is slidably installed inside the drive cavity 301 along the axial direction, and a drive plate 7 is fixed on the drive rod 5. An elastic drive element 8 is provided between the drive plate 7 and the inner end wall of the drive cavity 301. The elastic drive element 8 is a spring. The elastic drive element 8 is used to drive the elastic drive element 8. It should be noted that a connector 7 is also fixed on the top of the drive plate 7. A slide groove 21 communicating with the drive cavity 301 is opened on the window break tube 3 along the length direction. The connector 7 is slidably installed inside the slide groove 21 along the length direction. A toothed rod 10 is fixed on the top of the connector 7 through the slide groove 21. A drive structure 11 that works with the toothed rod 10 is installed on the top of the mounting plate 1. The drive structure 11 is used to drive the toothed rod 10.
[0025] In detail: the drive structure 11 includes a motor 1101 mounted on the mounting plate 1, and the output shaft of the motor 1101 is fixed with an incomplete gear 1102. During the rotation of the incomplete gear 1102, it can drive the rack 10 to move. If the incomplete gear 1102 disengages from the rack 10, the elastic drive member 8 can drive the drive rod 5 to move through the drive plate 7, so that the drive rod 5 can push out the breaking head a and break the window.
[0026] It should be noted that: the top of the window-breaking cylinder 3 is symmetrically fixed with parallel limiting rods 12 about the slide groove 21. The two limiting rods 12 are respectively provided with guide rods 13 along the length direction on opposite sides. The side of the toothed rod 10 is provided with a guide groove (not shown in the figure) that cooperates with the guide rods 13. The guide rods 13 are slidably installed inside the guide grooves. Through the cooperation of the guide rods 13 and the guide grooves, the toothed rod 10 is limited, preventing the toothed rod 10 from shaking during use, thereby improving the stability of the device.
[0027] A sealing cover 14 is installed at the opening on the top of the storage box 4. The sealing cover 14 is used to seal the storage box 4 and prevent the crushing head inside the storage box 4 from falling out. It should be noted that: the side of the sealing cover 14 and the side of the storage box 4 are respectively fixed with mounting bases 15. When the two mounting bases 15 are aligned with each other, they are connected by locking bolts 15, which can fasten the sealing cover 14 and prevent the sealing cover 14 from falling off the storage box 4.
[0028] It should be noted that: the interior of the sealing cover 14 is provided with an inwardly recessed groove, and several compression springs 16 are fixed at equal intervals inside the groove. The bottom ends of the multiple compression springs 16 are equipped with the same pressure plate 17. When the sealing cover 14 is closed with the storage box 4, the springs 16 can drive the pressure plate 17 to move downward. The pressure plate 17 can apply slight pressure to the crushing head a inside the storage box 4 to prevent the crushing head a from falling out of the window breaker 3.
[0029] In the case of breaking a window at a high altitude: the window breaking mechanism is transported to a suitable location by a drone, and then the motor 1101 is activated. The output shaft of the motor 1101 drives the incomplete gear 1102 to rotate. Since the incomplete gear 1102 is in a meshing state with the rack 10, it can drive the rack 11 to move. The rack 11 can drive the drive plate 7 to move through the connecting piece 9, so that the drive plate 7 can drive the drive rod 5 to move and apply pressure to the elastic drive member 8, causing the elastic drive member 8 to change from its original state to a compressed state. If the incomplete gear 1102... When 02 disengages from the rack 10, the elastic drive member 8 immediately returns from the compressed state to its original state and pushes the drive plate 7 to move, so that the drive plate 7 can drive the drive rod 5 to move quickly. The drive rod 5 can quickly eject the breaking head a, and the breaking head a can be used to break the window. Then, the same operation is performed. If the drive rod 5 retracts into the drive cavity 301, the breaking head a in the storage box 4 falls downward due to its own gravity. Then, the same operation is performed, and the breaking head a can be repeatedly ejected to break the window.
