Description

Technical Field

[0001] The utility model belongs to the field of window breaking tools used on board unmanned aerial vehicles, and in particular relates to a window breaking tool for unmanned aerial vehicles. Background Art

[0002] With the development of cities, high-rise rescue has become a new problem. Once an emergency occurs, breaking the exterior glass is the best way to get to the scene. Currently, most drone window-breaking systems on the market use multi-rotor drones to launch window-breaking bullets, which have the disadvantages of long aiming time and low accuracy. At the same time, special window-breaking bullets must be used. It is difficult to find substitutes for window-breaking bullets in emergency situations, which prolongs the rescue time. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a drone window breaking tool, which can be quickly aimed at the window breaking position at a close distance, can be used repeatedly, and has a high window breaking efficiency.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A window-breaking tool for an unmanned aerial vehicle comprises a guide tube, a telescopic rod and a toggle member.

[0006] The catheter is arranged under the UAV. When the UAV flies horizontally, the catheter is in a horizontal state. The front end of the catheter is an open structure and the rear end is closed. A strip hole is opened on one side of the catheter along the length direction, one end of which extends to the front end of the catheter and the other end is located in the middle section of the catheter. A stopper is arranged on the outer wall of the catheter corresponding to the strip hole located in the middle section of the catheter, and a guide slope is arranged on the side of the front end facing the middle section of the catheter.

[0007] The telescopic rod is slidably arranged in the conduit, a compression spring is arranged between the rear end of the telescopic rod and the rear end of the conduit, a hammer head parallel to the conduit is arranged at the front end of the telescopic rod, a latch is vertically penetrated through the middle of the telescopic rod, the front end of the latch passes through the strip hole, a support spring is arranged at the rear end of the latch, and when the support spring is in a natural state, the front end of the hammer head protrudes from the front end of the conduit;

[0008] The toggle member is arranged outside the strip hole and moves along the length direction of the conduit. The end of the toggle member facing the conduit has a chamfered surface that is in the same direction as the guide slope. The minimum distance between the chamfered surface and the outer wall of the conduit is greater than the minimum distance between the guide slope and the outer wall of the conduit.

[0009] When the front end of the pin extends to the outside of the catheter to the extreme position, the front end face of the pin is located within the range of the guide bevel and the chamfered surface in the projection view in the length direction of the catheter; when the pin moves a predetermined distance to the rear end, there is a gap between its front end and the toggle member, and the front end face of the pin is still located within the range of the guide bevel in the projection view in the length direction of the catheter.

[0010] The beneficial effects of the utility model are that the solution can quickly aim at the window breaking position at a close distance, thereby improving the window breaking efficiency, and can be used repeatedly to facilitate continuous impact on the glass. Compared with the method of firing window-breaking bullets, it saves the time of loading and aiming, has higher efficiency, and the threat range when breaking glass is smaller and safer.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] like Figures 1 to 5 As shown, a UAV window breaking tool includes: a guide tube 1, a telescopic rod 3 and a toggle member 5.

[0020] Specifically, the catheter 1 is arranged under the drone. When the drone flies horizontally, the catheter 1 is in a horizontal state. The front end of the catheter 1 is an open structure and the rear end is closed. A strip hole 11 is opened on one side of the catheter 1 along the length direction, one end of which extends to the front end of the catheter 1, and the other end is located in the middle section of the catheter 1. A stopper 2 is provided on the outer wall of the catheter 1 corresponding to the strip hole 11 located in the middle section of the catheter 1, and a guide slope 21 is provided on the side of the front end facing the middle of the catheter 1.

[0021] Specifically, the telescopic rod 3 is slidably arranged in the catheter 1, and a compression spring 31 is arranged between the rear end thereof and the rear end of the catheter 1, and a hammer head 32 parallel to the catheter 1 is arranged at the front end of the telescopic rod 3, and a latch 4 is vertically penetrated through the middle of the telescopic rod 3, and its front end passes through the strip hole 11, and a support spring 41 is arranged at the rear end of the latch 4, and the end of the support spring 41 can abut against the inner wall of the catheter 1, and when the support spring 41 is in a natural state, the front end of the hammer head 32 protrudes from the front end of the catheter 1;

[0022] Specifically, the toggle member 5 is movable along the length direction of the catheter 1 and is arranged on the outside of the strip hole 11, so that there is a gap between the toggle member 5 and the outer wall of the catheter 1, and the end of the toggle member 5 facing the catheter 1 has a chamfered surface 51 that is consistent with the direction of the guide bevel 21, and the minimum distance between the chamfered surface 51 and the outer wall of the catheter 1 is greater than the minimum distance between the guide bevel 21 and the outer wall of the catheter 1.

[0023] When the front end of the latch 4 extends outwardly of the catheter 1 to the limit position, the front end surface of the latch 4 is located within the range of the guide slope 21 and the chamfered surface 51 in the projection view in the length direction of the catheter 1. When the latch 4 moves to the rear end by a predetermined distance, there is a gap between its front end and the toggle member 5, and the front end surface of the latch 4 is still located within the range of the guide slope 21 in the projection view in the length direction of the catheter 1.

[0024] Working principle: Use a drone to move the conduit 1 to the window-breaking position, direct the front end of the conduit 1 towards the position on the glass to be impacted, and make the front end of the conduit 1 close to or adhere to the glass; in the initial state, the bolt 4 is located between the toggling member 5 and the stop block 2, and the front end of the bolt 4 extends outwards to the extreme position on the outside of the conduit 1. At this time, the support spring 41 can be in a natural extension state or a compressed state, but it is not compressed to the limit; then use a linear motor or a motor-screw mechanism to drive the toggling member 5 to move towards the rear end of the conduit 1. Because when the front end of the bolt 4 extends outwards to the extreme position on the outside of the conduit 1, the front end face of the bolt 4 is within the chamfered surface 51 in the projection view in the length direction of the conduit 1, so it can be ensured that there is an overlapping part between the front end of the bolt 4 and the toggling member 5, and the chamfered surface 51 and the guiding inclined surface 21 face the same direction, both towards the inside of the front end of the conduit 1. Therefore, when the toggling member 5 moves towards the rear end of the conduit 1, the side of the toggling member 5 opposite to the chamfered surface 51 will push the bolt 4 towards the rear end of the conduit 1, and the bolt 4 will drive the telescopic rod 3 towards the rear end of the conduit 1, and the compression spring 31 will be gradually compressed; after the front edge of the bolt 4 contacts the guiding inclined surface 21, continuing to move the toggling member 5 towards the rear end of the conduit 1 will cause the bolt 4 to move towards the rear end under the guiding action of the guiding inclined surface 21. At this time, the support spring 41 will be compressed. Since there is a gap between the front end of the bolt 4 and the toggling member 5 when the bolt 4 moves a predetermined distance towards the rear end, when the bolt 4 moves backwards to the predetermined position, the front end of the bolt 4 will be separated from the toggling member 5; once the bolt 4 loses the restriction of the toggling member 5, because the compression spring 31 has stored enough pressure, it will instantly recover its elastic deformation, thereby pushing the telescopic rod 3 to move quickly towards the front end of the conduit 1, and making the hammer head 32 quickly impact the glass, so that the glass is broken.

[0025] As Figure 4 、 Figure 5 shown, after the window-breaking is completed, the bolt 4 will be between the toggling member 5 and the front end of the conduit 1, and the support spring 41 will cause the bolt 4 to protrude outwards to the extreme position on the outside of the conduit 1 again. At this time, move the toggling member 5 towards the front end of the conduit 1, and the chamfered surface 51 can be used to contact the bolt 4 and push the bolt 4 to move backwards by using the chamfered surface 51, so that the bolt 4 avoids the toggling member 5 until the toggling member 5 moves in front of the bolt 4, making the bolt 4 return to the initial state for reuse.

[0026] This solution can quickly align with the window-breaking position at a short distance, improve the window-breaking efficiency, and can be reused repeatedly to facilitate continuous impact on the glass. Compared with the method of firing window-breaking bullets, it saves the time for loading and aiming, has higher efficiency, and has a smaller threat range when breaking the glass, making it safer.

[0027] Preferably, as Figure 1 、 Figure 4 shown, the stop block 2 is connected to the outer wall of the conduit 1 by screws.

[0028] Preferably, Figure 4 , Figure 5 As shown, the hammer head 32 is a rod-shaped structure with a conical structure at the front end, and the hammer head 32 is inserted into the countersunk hole opened at the front end of the telescopic rod 3, so that the hammer head 32 can be replaced after being worn; as a preferred structure, a locking screw can be passed through the side wall of the telescopic rod 3 to clamp the hammer head 32 to prevent the hammer head 32 from falling, and the head of the locking screw is embedded in the side wall of the telescopic rod 3 to avoid affecting the movement of the telescopic rod 3 in the catheter 1.

[0029] Preferably, Figure 1 , Figure 2 and Figure 4 , Figure 5 As shown, the outer side of the conduit 1 corresponding to the strip hole 11 is provided with a screw rod 61 and a guide rod 62 parallel to the strip hole 11, the screw rod 61 and the guide rod 62 both pass through the toggle member 5, and the screw rod 61 and the toggle member 5 are threadedly connected, and a motor 63 is provided on the conduit 1 for driving the screw rod 61 to rotate, so that the toggle member 5 can be driven to move along the length direction of the strip hole 11 by rotating the screw rod 61, and the movement process of the toggle member 5 is smoother and will not slip.

[0030] Preferably, Figure 3 As shown, a disc is provided at the rear end of the latch 4, and its outer diameter is larger than that of the latch 4. The end of the mounting hole of the telescopic rod 3 for penetrating the latch 4 has a countersunk hole for accommodating the disc, and a cover plate 33 is provided at the opening of the countersunk hole. The cover plate 33 is located in the telescopic rod 3 to prevent the cover plate 33 from contacting the inner wall of the catheter 1, thereby increasing the resistance when the telescopic rod 3 moves. The support spring 41 is provided in the countersunk hole and is located between the disc and the cover plate 33, thereby preventing the support spring 41 from contacting the inner wall of the catheter 1.

[0031] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
