Technical Field
[0001] This invention relates to the fields of unmanned aerial vehicle (UAV) technology and artillery firing technology, and in particular to a coaxial rotor artillery-fired fireworks UAV system. Background Technology
[0002] With the continuous development of fireworks drones and related technologies, fireworks drones are widely used in major festivals, national celebrations, opening ceremonies of large-scale sports events, tourist attractions and other occasions. Enterprises can also use fireworks drones for brand promotion and product promotion. However, existing fireworks drones generally have problems such as short battery life and poor fireworks pattern effects.
[0003] To address the issues of short flight time and poor fireworks pattern effects of drones, patent CN110282131A discloses a fireworks drone that combines fireworks with a drone to achieve aerial hovering and ignition of fireworks, with automatic ignition functionality. Patent CN107044805A discloses a fireworks projectile and a high-altitude fireworks launching system. The control unit in the fireworks projectile includes a microcontroller, which allows for precise control via computer programming, enabling more diverse and richer fireworks displays. Patent US11808556B2 discloses an integrated control device and method for igniting fireworks and flying drones in fireworks displays. The method involves receiving flight information from the drone and ignition information from the fireworks, generating flight control signals and ignition control signals, and receiving real-time flight status information and fireworks ignition status information. Patent JP2023103842A discloses an electric remote-controlled drone with rotors mounted on its fuselage. Firework components are mounted on the drone's support structure, and the flight controller is connected to a fireworks control circuit, allowing the launch of fireworks by sending operation signals.
[0004] The aforementioned methods suffer from several drawbacks: high energy consumption during drone takeoff, high power consumption during takeoff, short drone flight time, poor drone stability, slow takeoff speed, and insufficient energy storage to support a large-scale fireworks display. Furthermore, the firework patterns within the projectiles are pre-set, resulting in monotonous patterns and an inability to control the performance effects in real time. Summary of the Invention
[0005] The purpose of this invention is to provide a coaxial rotor artillery-launched fireworks drone system. This drone system has the ability to hover, can reach a certain height through artillery firing, and can withstand large overloads during launch, achieving clustered hovering in the air. It can also be used in conjunction with an airborne foldable fireworks guiding and launching system to complete large-scale fireworks displays.
[0006] The technical solution to achieve the purpose of this invention is: a coaxial rotor artillery-launched fireworks drone system, comprising an onboard shell, a drone, and a foldable fireworks guiding and launching system;
[0007] The missile-borne outer shell mainly includes the missile body, the missile tail, and the wind cap. The missile body and the missile tail are connected by a fixing mechanism. The fixing mechanism is equipped with a shell ejection mechanism, which realizes shell ejection and separation when a separation signal is received.
[0008] The overall structure, consisting of a drone and a foldable fireworks guide launch system, is folded and placed inside the projectile body. The drone consists of a foldable nose and fuselage. The foldable fireworks guide launch system consists of a guideable fireworks launch device and an airborne fireworks launcher. The airborne fireworks launcher includes a fireworks launch tube and a foldable cross connecting rod. The fireworks launch tube is connected to the drone through the foldable cross connecting rod and contains fireworks projectiles and propellant. It is carried into the air by the drone, remotely controlled, and ignited and launched using an electric ignition method.
[0009] Compared with the prior art, the significant advantages of the present invention are:
[0010] (1) This invention uses air-gun firing technology to launch a fireworks drone to a designated altitude in the air. Compared with traditional drones, this technology can reduce the drone's takeoff time, enabling the drone to achieve a higher initial velocity, while significantly saving energy consumption during the takeoff process, thereby extending the drone's flight time and ensuring sufficient energy storage to support large-scale fireworks displays. Compared with traditional fireworks, this invention uses air-gun firing technology, which greatly reduces the amount of propellant used in the fireworks; each fireworks projectile requires only a small amount of propellant.
[0011] (2) The fireworks launch tube designed in this invention can store a large number of fireworks marbles and propellant, enabling a single fireworks drone to complete multiple fireworks patterns. This ensures that a small number of micro-drones can be used to complete multiple large-scale fireworks shows. In addition, the structural design of the fireworks launch tube can also protect the drone and assist it in landing.
[0012] (3) The present invention has designed a guideable firework launcher at the nozzle of the firework launch tube, which can remotely adjust the direction of the firework at any time through the servo motor, assisting in the formation of highly controllable firework patterns, increasing the richness of the patterns of the drone firework show, and making up for the shortcomings of traditional firework shows that cannot control the firework patterns in real time.

Detailed Implementation
[0021] This invention addresses the problems and shortcomings of existing fireworks drones by providing a coaxial rotor cannon-launched fireworks drone system. It uses an air cannon to launch the fireworks drone to a designated altitude for hovering, thereby saving power consumption during takeoff and solving the problems of short flight time and slow ascent speed. The fireworks launch tube increases the payload capacity of the fireworks drone, allowing a small number of micro-drones to achieve the effect of a large-scale fireworks show. The launch tube also protects the drone and assists with landing. A guideable fireworks launcher head adjusts the firing angle and direction of the fireworks, assisting in the design of highly controllable fireworks patterns and overcoming the shortcomings of traditional fireworks drone performances, such as limited pattern variety and the inability to control the performance effect in real time.
[0022] like Figure 1As shown, this invention proposes a coaxial rotor artillery-launched fireworks drone system, including an onboard shell, a drone, and a foldable fireworks guiding and launching system. The onboard shell mainly includes a projectile body 1, a tail 2, and a wind cap 3. The projectile body 1 and the tail 2 are connected by a fixing mechanism, which contains a shell ejection mechanism that can eject and separate the shell upon receiving a separation signal. The drone and the foldable fireworks guiding and launching system are arranged in a folded state and placed inside the projectile body 1. The drone consists of a foldable nose 14 and a fuselage 15. The foldable fireworks guiding and launching system consists of a guideable fireworks launching device and an airborne fireworks launching frame. The airborne fireworks launching frame includes a fireworks launching tube 10 and a foldable cross connecting rod. The fireworks launching tube 10 is connected to the drone through the foldable connecting rod and contains fireworks projectiles and propellant. The drone carries the fireworks into the air, remotely controls them, and ignites and launches the fireworks using electric ignition.
[0023] The directional fireworks launching device and the airborne fireworks launching rack are also a protective device for the UAV. The protective device can carry fireworks projectiles while preventing the UAV from coming into close contact with the fireworks in the fireworks launching tube (10), which can reduce the heat being conducted into the UAV and ensure the safe landing of the UAV, thus protecting the UAV.
[0024] The airborne fireworks launcher is equipped with an ignition circuit, which consists of a battery, a receiver, and an electric ignition wire. The fireworks launch effect is controlled by controlling the electric ignition wire, and the fireworks pattern can be programmed. The electric ignition wire is embedded inside the fireworks launch tube 10. When the receiver receives a designated signal, the electric ignition wire ignites the propellant in the fireworks launch tube 10 and launches the fireworks projectile.
[0025] Furthermore, in the aforementioned coaxial rotor-launched fireworks drone system, the projectile body 1 and the projectile tail 2 protruding portions are provided with four equidistant small holes of the same diameter, which are fixedly connected by pins 18. Simultaneously, an ejection mechanism is provided at the connection point of the two, which includes an electric ignition device 16 and an ejection block 17. The electric ignition device 16 is cylindrical, with a thin electric ignition wire extending from within the device to the hollow portion inside the ejection block, which is filled with a small amount of gunpowder. The ejection block 17 fits into the groove formed by the projectile tail protrusion, and its sidewall and the projectile tail protrusion are respectively provided with four equidistant small holes of the same diameter. The pins 18 thus simultaneously connect and fix the projectile body, the projectile tail, and the ejection block.
[0026] Furthermore, in the aforementioned coaxial rotor artillery-launched fireworks drone system, the wind cap 3 is nested above the projectile body 1 through its protruding part, and the overall structure consisting of the drone and the foldable fireworks guiding and launching system is placed in a folded state within the enclosed space composed of the projectile body 1, the tail 2 and the wind cap 3.
[0027] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks drone system, this invention employs an air cannon launching device to launch the integrated system, consisting of the missile-borne outer shell, the drone, and the foldable fireworks guiding and launching system, into the air. Before launch, the air cannon is loaded with the nozzle tip pointing in the direction of muzzle ejection. When the launch signal is given, the air cannon uses high-pressure gas to propel the system of this invention towards the predetermined location.
[0028] Furthermore, in the aforementioned coaxial rotor-launched fireworks drone system, an ejection mechanism is installed between the projectile body 1 and the tail 2 of the projectile-borne outer shell. When the system reaches a designated height and angle, the electric ignition device 16 ignites the pre-loaded gunpowder in the ejection block 17 via an extended electric ignition wire. The ejection block 17 is made of PLA material and 3D printed, with a very thin bottom in its hollow portion. The ignited gunpowder directly blasts open the bottom of the ejection block 17, and the expanding gas from the gunpowder propels the ejection block 17 upwards. Subsequently, the ejection block 17 directly impacts the folded drone and the foldable fireworks guide launch system, causing the entire system to continue upwards and push out the wind cap 3. This achieves the purpose of releasing the folded drone and fireworks launch system.
[0029] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks drone system, the drone consists of two foldable nose sections 14 and a fuselage 15. The two coaxially distributed drone nose sections 14 improve space utilization and facilitate the installation of foldable fireworks launchers.
[0030] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks drone system, a foldable cross connecting rod is fixedly installed through the middle of the drone fuselage. The foldable cross connecting rod is composed of a cross center rod 12 and a cross folding rod 11. The cross center rod 12 is fixedly installed through the center of the drone fuselage and is connected to the cross folding rod in a hinge manner with a pin.
[0031] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks drone system, the fireworks launch tube 10 is connected to the cross-folding rod 11 via a hinge, and there are a total of four fireworks launch tubes, which are respectively fixed to one end of the four cross-folding rods in the middle.
[0032] Furthermore, in the aforementioned coaxial rotor-launched fireworks drone system, the upper and lower ends of the four fireworks launch tubes are still connected to foldable cross-shaped connecting rods in a cross shape via hinges. Each of the upper, middle, and lower sections of the airborne fireworks launch tube is fixed by a foldable cross-shaped connecting rod. This connection method stabilizes the position of the airborne fireworks launch tube and makes it less prone to displacement.
[0033] Furthermore, in the aforementioned coaxial rotor artillery-launched fireworks drone system, the foldable cross connecting rod can be folded and tightened inwards, loaded into the shell, and unfolded after the shell completes the ejection operation until the drone completes its performance and lands safely.
[0034] Furthermore, in the aforementioned coaxial rotor artillery-launched fireworks drone system, the foldable cross connecting rod and the four airborne fireworks launch tubes constitute an airborne fireworks launcher, forming a foldable cage structure that encloses the drone. While serving to load fireworks projectiles, it also prevents the drone from coming into close contact with the fireworks inside the launch tubes, ensuring the safe landing of the drone and providing protection for it.
[0035] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks UAV system, the guideable fireworks launching device consists of a guide head 4, a fixed head 9, a pin, a rotating shaft 6, a servo motor, and a matching power supply battery. The upper body is the guide head 4, and the lower body is the fixed head 9. The fixed head 4 is fixed to the outlet of the fireworks launching tube, thus fixing the entire guideable fireworks launching device to the airborne fireworks launching frame. The guide head 4 and the fixed head 9 are connected by a hinge. Under the control of the servo motor, the guide head 4 can swing to change the relative angle between the upper and lower parts.
[0036] Furthermore, in the aforementioned coaxial rotor-launched fireworks drone system, the guide head 4 and fixed head 9 in the guideable fireworks launching device are made of lightweight composite materials. A high-temperature resistant flexible tube 5 is nested within the central bore of the guide head 4 and fixed head 9. The flexible tube bends as the relative angle between the upper and lower heads changes. The fireworks powder is launched vertically upwards along the fireworks launching tube, and after passing through the flexible tube, it is launched along the bending direction of the tube, thus changing the launch trajectory of the fireworks powder itself. This also prevents excessive deformation caused by the heat generated during fireworks combustion, ensuring stable and precise control of the launch angle.
[0037] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks UAV system, the guideable fireworks launching device is fixed to the launching port at the top of the airborne fireworks launching tube by bolts.
[0038] Furthermore, in the aforementioned coaxial rotor cannon-launched fireworks drone system, the rotation of the rotating shaft 6 in the steerable fireworks launcher is controlled by the servo motor 8. After receiving a designated signal, the servo motor 8 drives the steerable fireworks launcher to deflect in a predetermined direction, thereby controlling the direction of the fireworks launch, so that a small number of drones can create a variety of fireworks patterns.
[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Example
[0041] like Figures 1-7As shown, this embodiment of the invention provides a gun-launched coaxial rotor fireworks drone system, which includes a missile-borne shell, a drone, and a foldable fireworks guiding and launching system.
[0042] The missile's outer casing mainly comprises the missile body 1, the tail 2, and the wind cap 3. The protruding parts of the missile body 1 and tail 2 have four equidistant small holes of the same diameter, which are fixedly connected by pins 18. An ejection mechanism is provided at the connection point between the two, which includes an electric ignition device 16 and an ejection block 17. The electric ignition device 16 is cylindrical, and a thin electric ignition wire extends from the device to the hollow part inside the ejection block 17. The hollow part is filled with a small amount of gunpowder, such as... Figure 7 As shown. The ejector block 17 fits into the groove formed by the protruding part of the tail 2, and its side wall and the protruding part of the tail 2 are respectively provided with four small holes of the same diameter as described above, which are equidistantly arranged. The pin 18 thus connects and fixes the projectile body 1, the tail 2 and the ejector block 17 simultaneously. The wind cap 3 is nested into the top of the projectile body 1 through its own protruding part. The whole structure consisting of the UAV and the foldable fireworks guide launch system is placed in a folded state in the closed space formed by the projectile body 1, the tail 2 and the wind cap 3.
[0043] In this embodiment, the drone consists of a foldable nose 14 and a body 15. A cross-shaped central rod 12 is fixed through the middle of the body 15 and is connected to the cross-shaped folding rod 11 in a hinge manner with a second pin 13.
[0044] In this embodiment, the foldable fireworks guiding and launching system includes a guideable fireworks launching device and a fireworks launching frame. The guideable fireworks launching device mainly consists of a guide head 4, a high-temperature resistant hose 5, a rotating shaft 6, a first pin 7, a servo motor 8, and a fixed head 9. The guide head 4 cooperates with the rotating shaft 6 and the first pin 7, and is connected to the fixed head 9 in a hinge manner. The outer side of the rotating shaft 6 is connected to the servo motor, which controls the rotation angle of the guide head 4. The fixed head 9 is nested and fixed at the top of the fireworks launching tube 10, ensuring that the connecting axis between the servo motor 8 and the rotating shaft 6 points outwards from the system and is perpendicular to the UAV fuselage, thus ensuring that the angle between the guide head 4 and the fixed head 9 is correctly deflected during operation. The fireworks launching frame includes a fireworks launching tube 10, a cross-shaped folding rod 11, a cross-shaped center rod 12, and a second pin 13. The fireworks launching tube 10 is parallel to the vertical direction of the UAV fuselage and is arranged in the four directions of the UAV: front, back, left, and right. The fireworks launch tube 10 has three hinges at the top, middle and bottom that cooperate with the second pin 13 to connect to the cross-shaped folding rod 11, which in turn connects to the central cross rod 12 located in the center.
[0045] In this embodiment, the system of the present invention will be used as an air cannon launching device to... Figure 1The entire system shown is launched into the air. Before launch, the air cannon is loaded with the tip of the wind cap 3 pointing in the direction of muzzle discharge. When the launch signal is given, the air cannon uses high-pressure gas to propel the system of this invention toward the predetermined location.
[0046] In this embodiment, an ejection mechanism is installed between the missile body 1 and the missile tail 2 of the missile casing. For example... Figure 7 As shown, when the system of the present invention reaches the designated height and angle, the electric ignition device 16 ignites the gunpowder pre-loaded in the ejector block 17 via the extended electric ignition wire. Since the ejector block 17 is made of PLA material and 3D printed, and its hollow bottom is very thin, the ignited gunpowder will directly blast open the bottom of the ejector block 17, and the expanding gas from the gunpowder will propel the ejector block 17 upwards. Subsequently, the ejector block 17 will directly impact the folded drone and the foldable fireworks guide launch system, causing the entire system to continue upwards and push out the wind cap 3. This achieves the release of... Figure 2 The purpose of the drone and fireworks launching system shown in the folded state.
[0047] In this embodiment, the drone, the fireworks launch tubes, and the four fireworks launch tubes are connected by a foldable cross-shaped connecting rod consisting of a cross-shaped folding rod 11, a cross-shaped central rod 12, and a second pin. When the drone and the fireworks launching system detach from the projectile 1, the upper, middle, and lower sets of foldable cross-shaped connecting rods will jointly drive the four sets of fireworks launch tubes (front, rear, left, and right) to unfold off-axis relative to the drone's central axis. (Reference) Figure 4 As shown, after unfolding, the fireworks launch tube 10 will remain parallel to the surface of the drone fuselage 15, ensuring the stability of the fireworks launch. Simultaneously, the three sets of foldable cross-shaped connecting rods (top, middle, and bottom) and the four sets of fireworks launch tubes together form a cage-like structure, enclosing the drone body. This provides a certain degree of protection for the drone and also functions as landing gear during descent. The foldable cross-shaped structure acts as a buffer during drone landing, protecting the safety of important and delicate internal components.
[0048] In this embodiment, a ring-shaped thin plate is connected below the servo motor 8. The thin plate is located directly below the fixing head 9 and is nested on the fireworks launch tube 10 to fix it and ensure the stable operation of the servo motor 8.
[0049] In this embodiment, a miniature ignition circuit is fixed on the fireworks launcher. The ignition circuit consists of a battery, a receiver, and an electric ignition wire. The electric ignition wire is embedded inside the fireworks launch tube 10. When the receiver receives a designated signal, the electric ignition wire ignites the propellant in the fireworks launch tube 10, launching the fireworks projectile and realizing the launch of fireworks at a designated time on the UAV.
[0050] In this embodiment, when it is necessary to change the launch angle of the fireworks projectile, the servo motor 8 will control the guide head 4 to deflect to a predetermined angle via the rotating shaft 6, thereby causing the high-temperature resistant hose 5 to bend and change the launch path of the fireworks projectile, thus achieving control over the launch of the fireworks projectile. The high-temperature resistant hose 5 is made of a special high-temperature resistant material to ensure that the high temperature conditions caused by repeated launches of fireworks projectiles do not affect the normal operation of the hose and other key components of the guideable fireworks launch device.
[0051] Before launching the drone, the prepared fireworks projectiles and propellant are loaded into the fireworks launch tube 10, and an ignition wire is embedded in the fireworks launch tube 10. Then, as follows... Figure 1 After folding the coaxial rotor artillery-launched fireworks drone, it was inserted into the projectile body 1, and then... Figure 1 The entire system, including the projectile to be fired, is loaded into the air cannon launching device for firing preparation. After calculating the air cannon's launch angle and altitude, the projectile is launched to the designated altitude and location. The drone and the foldable fireworks guiding and launching system are then deployed and released via the projectile ejection device. Figure 3 The drone deploys its external fireworks launch tube 10 and hovers. After hovering, it begins preparations for a fireworks display. In this embodiment, the fireworks release is remotely controlled by a miniature ignition circuit fixed on the fireworks launcher. This ignition circuit includes a battery, a receiver, and an electric ignition wire. When releasing the fireworks, a control signal is transmitted from the ground at a predetermined time. Upon receiving the signal, the receiver ignites the electric ignition wire embedded in the fireworks launch tube 10, thus igniting the propellant and releasing the fireworks projectile. Simultaneously, the external receiver of the servo motor 8 receives a designated signal and adjusts the deflection of the guide head 4 according to the predetermined fireworks pattern to adjust the launch direction of the fireworks and produce the predetermined fireworks pattern. Through this embodiment, multiple fireworks patterns can be produced, achieving the goal of completing multiple large-scale fireworks shows using a small number of drones.
