[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle capable of sticking to a wall. Background Art

[0002] When facing high-rise fire rescue or performing certain special tasks, it is often necessary to break windows in high-rise buildings to implement emergency evacuation or rescue operations. However, the current methods mostly rely on operators to climb up and manually break windows after approaching the designated window position. This method is not only time-consuming and labor-intensive, greatly reducing the efficiency of rescue, but also due to the complex and changeable high-altitude working environment, operators face extremely high safety risks. Therefore, the development of more efficient and safe window breaking technology is of great significance to improving the rescue speed and protecting the lives of rescuers.

[0003] A Chinese patent (publication number: CN216375005U) discloses a window-breaking UAV; two fixing frames are provided at the front end of the UAV fuselage, and a number of window-breaking heads are distributed on each of the fixing frames; the end face of the fixing frame away from the UAV fuselage is an arc-shaped surface, and the window-breaking heads are arranged on the arc-shaped surface; the UAV flight speed and overall mass are used to realize energy conversion during collision; but in actual use, it is found that the patent has a complex structure and a low success rate of window breaking. Summary of the invention

[0004] In order to overcome the deficiencies in the background technology, the present invention discloses a drone capable of sticking to a wall.

[0005] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: A drone capable of sticking to a wall comprises a multi-rotor drone body, a connecting rod, a wall sticking device and a window breaking hammer; both sides of the multi-rotor drone body are connected to the connecting rods, one end of one connecting rod away from the multi-rotor drone body is equipped with a window breaking hammer, and the other end of the connecting rod away from the multi-rotor drone body is equipped with the wall sticking device; The wall-adhering device includes a wall-adhering board, one side of the wall-adhering board is provided with adhesive, the other side is provided with a hinge seat, the hinge seat is hinged with a hinge head through a hinge shaft, and the hinge head is correspondingly and tightly connected with the corresponding connecting rod; the hinge shaft body is sleeved with a torsion spring for driving the connecting rod to deflect; the side of the wall-adhering board corresponding to the hinge head is provided with a limiting mechanism for keeping the torsion spring in a charged state.

[0006] Preferably, the limiting mechanism comprises a limiting block fastened corresponding to one side of the hinged joint, the wall plate is fastened with a mounting seat corresponding to the hinged joint, and the mounting seat body is equipped with a linear servo whose telescopic rod can engage with the limiting block.

[0007] Preferably, a countersunk hole is provided at one end of the linear servo telescopic rod corresponding to the limit block, a locking rod is movably inserted in the countersunk hole, a spring is provided between the locking rod and the bottom of the countersunk hole, and a cap is installed at the position of the telescopic rod corresponding to the countersunk hole mouth to prevent the locking rod from falling out.

[0008] Preferably, limit rings are installed at both ends of the hinge shaft.

[0009] Preferably, the window breaking hammer comprises a hammer body which is fastened to a corresponding connecting rod, and a spike is installed on the top of the hammer body.

[0010] Preferably, a slideway is provided in the hammer body, and a ball or a slider is slidably connected in the slideway.

[0011] Preferably, a counterweight is threadedly connected to one end of the hammer body away from the spike.

[0012] Preferably, the connecting rod is a hollow rod body.

[0013] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: The invention discloses a drone capable of sticking to a wall, which has a simple structure, is easy to assemble, and has a low production cost. Connecting rods are respectively provided on both sides of the main body of the multi-rotor drone, wherein one end of the connecting rod away from the main body of the drone is equipped with a window-breaking hammer, and the other end of the connecting rod away from the main body of the multi-rotor drone is equipped with a wall-sticking device. When performing a window-breaking task, the operator controls the main body of the multi-rotor drone to approach the target window until the adhesive surface on the wall-sticking board contacts and firmly adsorbs the glass surface of the window. Next, by releasing the locking of the limit device and activating the torsion spring, the connecting rod and the main body of the multi-rotor drone and the window-breaking hammer connected thereto are rapidly deflected upward, and finally the window is broken by the power of the window-breaking hammer. In this process, the operator can also choose to shut down the power system of the drone or adjust its flight attitude to enhance the impact effect of the window-breaking hammer and improve the success rate of window-breaking.

After the locking rod is misaligned with the limit block, the locking rod automatically extends and resets under the action of the spring, thereby automatically engaging with the limit block to achieve a locked state. The entire locking process does not require the linear servo to be operated again, and the structure is simple and easy to use.

[0015] The invention further provides a slideway inside the hammer body, in which a ball or a slider is slidably connected. When the window-breaking hammer collides with the window, the ball or the slider will continue to move forward under the action of its own inertia and hit the front end of the hammer body. This design enables the spike to hit the window again after the initial impact, thereby significantly improving the success rate of breaking the window. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0019] Embodiment 1, in combination with Figures 1 to 3 A drone capable of sticking to a wall comprises a multi-rotor drone body 1, a connecting rod 2, a wall sticking device 3 and a window breaking hammer 4; the multi-rotor drone body 1 is equipped with connecting rods 2 on both sides, one end of the connecting rod 2 away from the drone body is equipped with a window breaking hammer 4, and the other end of the connecting rod 2 away from the multi-rotor drone body 1 is equipped with a wall sticking device 3; It should be noted that in order to ensure that the multi-rotor UAV body 1 maintains good balance and maneuverability in the air, the mass of the wall-sticking device 3 and the window-breaking hammer 4 should be consistent to avoid operational difficulties caused by uneven mass distribution; the connecting rod 2 is a hollow rod body, which can effectively reduce the take-off weight of the multi-rotor UAV body 1.

[0020] As attached Figure 2As shown, the wall-mounted device 3 includes a wall-mounted board 3-1; one side of the wall-mounted board 3-1 is coated with adhesive for tightly adhering to the glass of the window when needed; the other side of the wall-mounted board 3-1 is provided with a hinge seat 3-2, and the hinge seat 3-2 is hinged with a hinge head 3-4 through a hinge shaft 3-3, and the hinge head 3-4 is further firmly connected to the corresponding connecting rod 2. The shaft body of the hinge shaft 3-3 is sleeved with a torsion spring 3-5 for driving the connecting rod 2 to deflect. In order to ensure that the torsion spring 3-5 can play a role at the appropriate time, a limit device 5 is also provided on the wall-mounted board 3-1 to maintain the preloaded state of the torsion spring 3-5. It is worth noting that in order to prevent the hinge shaft 3-3 from accidentally falling off from the hinge seat 3-2, or the torsion spring 3-5 from accidentally falling off from the hinge shaft 3-3, limit retaining rings 3-6 are installed at both ends of the hinge shaft 3-3.

[0021] When performing a task, the operator first remotely controls the multi-rotor drone body 1 to approach the target window until the adhesive surface on the wall plate 3-1 contacts the glass surface of the window and is firmly adsorbed; next, by releasing the lock of the limit device 5, the torsion spring 3-5 is activated, so that the connecting rod 2 and the multi-rotor drone body 1 and the window breaker 4 connected thereto are rapidly deflected upward, and finally the window is broken by the power of the window breaker 4. In this process, the operator can also choose to shut down the drone's power system or adjust its flight attitude to enhance the impact effect of the window breaker 4 and increase the success rate of breaking the window; it should be noted that the multi-rotor drone body 1 can carry the existing fire extinguishing bombs sold on the market. After breaking the window, the multi-rotor drone body 1 can carry the fire extinguishing bombs and flip into the window. Starting the fire extinguishing bombs can realize automatic fire extinguishing operations.

[0022] The limiting device 5 includes a limiting block 5-1 fixedly connected to the hinged joint 3-4, and a mounting seat 5-2 mounted on the wall plate 3-1. A linear servo 5-3 is arranged inside the mounting seat 5-2, and its telescopic rod can be engaged with the limiting block 5-1. Before the multi-rotor drone body 1 is ready to take off, the linear servo 5-3 is controlled to shorten and retreat, so that the wall plate 3-1 rotates around the hinge shaft 3-3 to a position perpendicular to the connecting rod 2, and the linear servo 5-3 is controlled to extend and reset, so that the limiting block 5-1 is engaged with the telescopic rod of the linear servo 5-3, so that the torsion spring 3-5 enters the energy storage state. When it is necessary to start the window breaking program, it is only necessary to control the telescopic rod of the linear servo 5-3 to retract and release the constraint on the limiting block 5-1 to trigger the entire window breaking action.

[0023] Example 2. It is observed in actual application that when it is necessary to store force in the torsion spring 3-5, the operation process is relatively complicated. Specifically, the telescopic rod of the linear servo 5-3 must first be controlled to shorten and retreat before the wall plate 3-1 can be deflected. After the wall plate 3-1 is perpendicular to the corresponding connecting rod 2, the telescopic rod of the linear servo 5-3 is controlled to extend again to achieve precise engagement with the limit block 5-1. This series of steps not only increases the difficulty of operation, but also takes a long time, affecting the overall operating efficiency. In order to solve the above defects, this example is further improved; Combined with Figures 2-3 , a drone that can stick to a wall, which is different from Example 1 in that, based on Example 1, a countersunk hole is provided at one end of the telescopic rod of the linear servo 5-3 corresponding to the limit block 5-1; a locking rod 5-4 is movably inserted in the countersunk hole, and a spring 5-5 is provided between the locking rod 5-4 and the bottom of the countersunk hole. A cap 5-6 is installed at the position of the telescopic rod corresponding to the opening of the countersunk hole to prevent the locking rod 5-4 from falling out. When the torsion spring 3-5 is charged, the wall plate 3-1 can be directly deflected; when the limit block 5-1 contacts the locking rod 5-4, the locking rod 5-4 will automatically retreat under the pushing action of the limit block 5-1. After the locking rod 5-4 is misaligned with the limit block 5-1, the locking rod 5-4 automatically extends and resets under the action of the spring 5-5, thereby automatically engaging with the limit block 5-1 to achieve a locked state. The entire locking process does not require the linear servo 5-3 to be operated again, and the structure is simple and easy to use.

[0024] Embodiment 3, in combination with Figure 1 and 4 , a drone capable of sticking to a wall, based on embodiment 1 or 2, the window breaking hammer 4 comprises a hammer body 4-1 correspondingly and firmly connected to the corresponding connecting rod 2. A spike 4-2 is installed on the top of the hammer body 4-1, and the spike is designed to be sharp and strong, and can effectively penetrate the window glass, ensuring the reliability of the window breaking effect.

[0025] A slideway 4-3 is provided inside the hammer body 4-1, and a ball or a slider is slidably connected inside the slideway 4-3. When the window-breaking hammer 4 hits the window, the ball or the slider will continue to move forward under the action of its own inertia and hit the front end of the hammer body 4-1. This design enables the spike 4-2 to hit the window again after the initial impact, thereby significantly improving the success rate of breaking the window.

[0026] In order to further optimize the performance of the window-breaking hammer 4, a counterweight 4-4 is installed at one end of the hammer body 4-1 away from the spike 4-2 by threaded connection. The counterweight 4-4 can be replaced with models of different quality specifications according to actual needs, thereby ensuring that the quality of the wall-attaching device 3 and the window-breaking hammer 4 is consistent. This design not only helps to maintain the overall balance of the drone, but also improves the stability and safety of operation.

[0027] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
