Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicle, and particularly relates to a fireworks performance unmanned aerial vehicle. BACKGROUND

[0002] In recent years, the fireworks performance of unmanned aerial vehicle formation has become a routine project of commercial promotion and festival ceremony. In order to reduce the risk of burning of the unmanned aerial vehicle body caused by too close nozzle, the nozzle of the fireworks is generally arranged in a horizontal outward extending form as far as possible from the unmanned aerial vehicle body. However, this horizontal outward extending arrangement makes the fireworks mass concentrated on the lateral far end of the unmanned aerial vehicle body, resulting in the imbalance of the center of gravity of the unmanned aerial vehicle body and the occurrence of tilting in the pre-takeoff stage and the post-landing stage. SUMMARY

[0003] The present application solves the technical problem of providing a fireworks performance unmanned aerial vehicle to solve the problem of tilting of the unmanned aerial vehicle in the pre-takeoff stage and the post-landing stage due to the imbalance of the center of gravity caused by the arrangement of the nozzle far away from the unmanned aerial vehicle body in the prior art.

[0004] In order to solve the above technical problem, the technical scheme adopted by the present application is as follows: a fireworks performance unmanned aerial vehicle, comprising an unmanned aerial vehicle body; a lifting slide rail connected to the unmanned aerial vehicle body and extending in a vertical direction; a lifting slide carriage in sliding cooperation with the lifting slide rail, used for mounting a fireworks with downward nozzle; when the unmanned aerial vehicle body takes off, the lifting slide carriage descends along the lifting slide rail by gravity.

[0005] The fireworks performance unmanned aerial vehicle provided by the present application cooperates the lifting slide carriage descending by gravity through the lifting slide rail, so that the fireworks with downward nozzle automatically slides down after the unmanned aerial vehicle leaves the ground, increases the vertical distance from the fuselage to reduce the risk of burning, and eliminates the lateral center of gravity moving outward caused by horizontal outward extension, so as to keep the center of gravity stable before takeoff and after landing; before takeoff, the bottom of the fireworks contacts the takeoff point to form an additional support point, reducing the tilting probability; during landing, the bottom of the fireworks contacts the landing point before the main landing gear to provide cushioning, and continues to contact after landing to form auxiliary support, further reducing the risk of tilting.

DETAILED DESCRIPTION

[0008] To explain the technical content, the purpose and the effect of the present application in detail, the following will be explained in conjunction with the embodiments and the accompanying drawings.

[0009] Please refer to Figure 1 A fireworks performance UAV, comprising a UAV body 1, a lifting slide rail 2 and a lifting sliding frame 3; the lifting slide rail 2 is connected to the UAV body 1 and extends in the vertical direction; the lifting sliding frame 3 is in sliding cooperation with the lifting slide rail 2 and is used for mounting a fireworks 4 with a downward nozzle; when the UAV body 1 takes off, the lifting sliding frame 3 relies on the weight to descend along the lifting slide rail 2.

[0010] From the above description, the beneficial effects of the present application are that the cooperation of the lifting slide rail 2 and the lifting sliding frame 3 descending by gravity makes the fireworks 4 with a downward nozzle automatically glide after the UAV leaves the ground, increases the vertical distance from the fuselage to reduce the risk of burning, and eliminates the lateral center of gravity moving outward caused by horizontal extension, keeping the center of gravity stable before takeoff and after landing; before takeoff, the bottom of the fireworks 4 contacts the takeoff point to form an additional support point, reducing the probability of toppling; during landing, the bottom of the fireworks 4 contacts the landing point before the main foot stand 13 to provide cushioning, and continues to maintain contact after landing to form auxiliary support, further reducing the risk of toppling.

[0011] Please refer to Figure 2 Further, the lifting slide rail 2 is detachably mounted on the UAV body 1.

[0012] From the above description, the lifting slide rail 2 is detachable, which facilitates quick installation before performance and quick removal after performance, improves replacement efficiency, and reduces transportation volume.

[0013] Please refer to Figure 1Further, the unmanned aerial vehicle body 1 is further provided with a mounting bracket 14, and the lifting slide rail 2 is mounted on the mounting bracket 14.

[0014] From the above description, the lifting slide rail 2 is connected to the unmanned aerial vehicle body 1 through the mounting bracket 14, and direct machining of the slide rail interface on the unmanned aerial vehicle body 1 is avoided, thereby simplifying manufacturing and maintenance.

[0015] Please refer to Figure 2 Further, the mounting bracket 14 is detachably mounted on the unmanned aerial vehicle body 1.

[0016] From the above description, the mounting bracket 14 is detachable, so that the unmanned aerial vehicle body 1 can be separated from the lifting slide rail 2, the lifting slide carriage 3 and the fireworks 4, thereby facilitating modular management and on-site quick replacement.

[0017] Please refer to Figure 3 and Figure 4 Further, the mounting bracket 14 is provided with a limiting protrusion 141, and the limiting protrusion 141 is located below the lifting slide rail 2 and used for abutting against the lifting slide carriage 3.

[0018] From the above description, the limiting protrusion 141 prevents the lifting slide carriage 3 from continuing to slide downward, so as to clearly define the limit position of the lifting slide carriage 3.

[0019] Please refer to Figure 6 Further, the limiting protrusion 141 is provided with a first magnetic attraction member 143, the lifting slide carriage 3 is provided with a second magnetic attraction member 311, and the first magnetic attraction member 143 is used for magnetic attraction cooperation with the second magnetic attraction member 311.

[0020] From the above description, the first magnetic attraction member 143 and the second magnetic attraction member 311 are arranged to be magnetically attracted and cooperated, so that the lifting slide carriage 3 is temporarily fixed at the end of the sliding, the shaking in flight is reduced, and the lifting slide carriage 3 is allowed to be separated when the landing impact is too large, thereby retaining the sliding buffering capability.

[0021] Please refer to Figure 5 Further, the mounting bracket 14 is provided with a level 142.

[0022] From the above description, the level 142 can provide an angle reference for the mounting bracket 14, so as to ensure that the lifting slide rail 2 is in a vertical state, thereby avoiding sliding jamming and nozzle deflection.

[0023] Please refer to Figure 1 and Figure 2 Further, the lifting slide carriage 3 comprises a sliding part 31 and two elastic clamping arms 32 connected to the sliding part 31, the sliding part 31 is in sliding cooperation with the lifting slide rail 2, and the two elastic clamping arms 32 are clamped to the side wall of the fireworks 4.

[0024] As can be seen from the above description, the elastic clamping arm 32 can achieve elastic clamping of the firework 4, adapt to the common diameter differences of the firework 4, and simplify the clamping operation.

[0025] Please refer to Figure 2 Furthermore, the end of the elastic clamping arm 32 away from the sliding part 31 is provided with a toggle protrusion 321.

[0026] As can be seen from the above description, the actuating protrusion 321 can provide a force point for opening the elastic clamp 32, which facilitates quick assembly and disassembly of the fireworks 4 and reduces the difficulty of operation.

[0027] Please refer to Figure 2 Furthermore, the inner wall of the elastic clamping arm 32 is provided with a damping element 33, which abuts against the side wall of the firework 4.

[0028] As can be seen from the above description, the damping component 33 can increase the friction and vibration attenuation between the elastic clamping arm 32 and the side wall of the firework 4, reduce the recoil of the firework 4 and the transmission of external vibration to the UAV body 1, and improve the connection stability.

[0029] Embodiment 1 of the present invention is as follows: Please refer to Figure 1 A fireworks display drone is suitable for nighttime celebration scenarios that require low-altitude, close-range, and high-precision formation flight and have limited site support conditions, including but not limited to hardened ground in city squares, commercial rooftop helipads, wooden boardwalks in scenic areas, temporary metal take-off and landing platforms, and ship decks, where large auxiliary support devices cannot be laid. It relies on the continuous contact between the fireworks 4 and the take-off point before take-off and the landing point after landing to form additional support points, which can compensate for the lack of stability caused by the small platform area or uneven surface. At the same time, the impact on the platform structure is reduced by the first contact of the fireworks 4 with the ground. It is suitable for short-term, rapid formation performance tasks with reusable fireworks 4 in densely populated areas or around valuable facilities.

[0030] Specifically, the fireworks display drone includes a drone body 1, a lifting rail 2, and a lifting sliding frame 3; the lifting rail 2 is connected to the drone body 1 and extends vertically; the lifting sliding frame 3 slides in cooperation with the lifting rail 2 to mount fireworks 4 with their nozzles facing downwards; when the drone body 1 takes off, the lifting sliding frame 3 descends along the lifting rail 2 by its own weight; more specifically, before takeoff, the bottom of the fireworks 4 contacts the takeoff point to form an additional support point, reducing the probability of tipping over; during landing, the bottom of the fireworks 4 contacts the landing point before the main landing frame 13 to provide cushioning, and continues to maintain contact after landing to form auxiliary support, further reducing the risk of tipping over.

[0031] In detail, the main body of the drone is provided with arms 11 around its perimeter, and propellers 12 are provided at the ends of the arms 11. Protective covers are provided around the propellers 12, and the bottom of the protective covers serves as the main landing gear 13 for the drone during takeoff and landing.

[0032] More specifically, before the drone body 1 takes off, the main landing gear 13 and the bottom of the firework 4 make contact with the supporting plane. The height from the bottom of the firework 4 to the connection point between the firework 4 and the lifting sliding frame 3 is greater than the height between the lifting slide rail 2 and the supporting plane. In other words, by the bottom of the firework 4 contacting the supporting plane, the lifting sliding frame 3 rises a certain distance from the lowest point of the lifting slide rail 2. When the drone body 1 leaves the supporting plane, under the action of gravity, the lifting sliding frame 3 will slide towards the lowest point of the lifting slide rail 2, causing the nozzle of the firework 4 to move away from the bottom of the drone body 1. It should be noted that in existing fireworks display drones, the space below is limited before takeoff and after landing. Therefore, the nozzle of the firework 4 is generally set horizontally or upward because there is sufficient space above and horizontally to extend the drone body, allowing the nozzle of the firework 4 to be as far away from the drone body 1 as possible. However, when the firework 4 is set horizontally away from the drone body 1, it is easy to cause the drone body 1 to lose its center of gravity. When the firework 4 is set upward away from the drone body 1, the sparks and slag ejected by the firework 4 are easy to fall onto the drone body 1, still posing a significant risk of burns. In contrast, this fireworks display drone sets the nozzle of the firework 4 vertically downward, avoiding the risk of the drone body tipping over due to a loss of balance. Furthermore, by setting up the lifting rail 2 and the lifting sliding frame 3 to slide together, the nozzle of the firework 4 can be set vertically downward away from the drone body 1 after the drone body 1 takes off, greatly reducing the risk of the drone body 1 being burned.

[0033] Please refer to Figure 2 The lifting slide rail 2 is detachably installed on the drone body 1, which facilitates quick installation before the performance and quick removal after the performance, improving replacement efficiency and reducing transportation volume. The detachable connection method includes, but is not limited to, at least one of screw connection, bolt connection, snap-fit ​​connection, pin connection or locking connection, which will not be described in detail here.

[0034] Please refer to Figure 1 and Figure 2In this embodiment, the drone body 1 is further provided with a mounting bracket 14, and the lifting slide rail 2 is mounted on the mounting bracket 14. It is understood that the mounting bracket 14 serves as a transitional connection between the lifting slide rail 2 and the drone body 1, avoiding the direct machining of the slide rail interface on the drone body 1, thus simplifying manufacturing and maintenance. Specifically, in this embodiment, the mounting bracket 14 is detachably mounted on the drone body 1. It is easy to understand that the detachable mounting bracket 14 allows the drone body 1 to be separated from the lifting slide rail 2, the lifting slide frame 3, and the fireworks 4, facilitating modular management and rapid on-site replacement. More specifically, the mounting bracket 14 is cross-shaped, with a horizontally extending collar 145 at its top. The collar 145 is fitted onto the top of the drone body 1. Buckles 144 are provided on both sides of the mounting bracket 14, engaging with the drone arm 11. This effectively ensures the accuracy of the mounting bracket 14's position and facilitates assembly and disassembly.

[0035] In other embodiments, the mounting bracket 14 may also be fixedly mounted on the drone body 1, and the specific configuration can be determined according to actual application requirements.

[0036] Please combine Figure 2 The lifting sliding frame 3 includes a sliding part 31 and two elastic clamping arms 32 connected to the sliding part 31. The sliding part 31 is slidably engaged with the lifting slide rail 2. The two elastic clamping arms 32 clamp the side wall of the firework 4. The elastic clamping arms 32 can achieve elastic clamping of the firework 4, adapt to the common diameter differences of the firework 4, and simplify the clamping operation. Specifically, the end of the elastic clamping arm 32 away from the sliding part 31 is provided with a toggle protrusion 321. The toggle protrusion 321 can provide a force application point to open the elastic clamping arm 32, which facilitates quick assembly and disassembly of the firework 4 and reduces the difficulty of operation. More specifically, the inner side wall of the elastic clamping arm 32 is provided with a damping element 33. The damping element 33 abuts against the side wall of the firework 4. The damping element 33 can increase the friction and vibration attenuation between the elastic clamping arm 32 and the side wall of the firework 4, reduce the recoil of the firework 4 and the transmission of external vibration to the UAV body 1, and improve the connection stability.

[0037] Optionally, the damping element 33 may be a damping adhesive layer or damping sticker attached to the inner wall of the elastic clamping arm 32.

[0038] Please refer to Figure 3 and Figure 4 Furthermore, the mounting bracket 14 is provided with a limiting protrusion 141, which is located below the lifting slide rail 2 and is used to abut against the lifting sliding frame 3. The limiting protrusion 141 can prevent the lifting sliding frame 3 from continuing to slide down, ensuring that the lowest position of the fireworks 4 is determined and preventing the fireworks 4 from interfering with other components on the drone body 1.

[0039] Please refer to Figure 5 Embodiment 2 of the present invention is a further improvement on Embodiment 1. In this Embodiment 2, a level 142 is provided on the mounting bracket 14, so as to provide an angle reference for the mounting bracket 14, ensuring that the lifting slide rail 2 is in a vertical state and avoiding sliding jamming and nozzle skew. Specifically, the level 142 is horizontally installed on the top of the mounting bracket 14. The level 142 can be a liquid level 142.

[0040] Please refer to Figure 6 Embodiment 3 of the present invention is a further improvement based on Embodiment 1. In this Embodiment 3: the limiting protrusion 141 is provided with a first magnetic suction member 143, and the lifting sliding frame 3 is provided with a second magnetic suction member 311. The first magnetic suction member 143 is used to magnetically engage with the second magnetic suction member 311. By setting the first magnetic suction member 143 and the second magnetic suction member 311 to magnetically engage, the lifting sliding frame 3 is temporarily fixed at the end of the descent, reducing swaying during flight, and allowing it to disengage when the landing impact is too large, thus retaining the sliding buffering capacity. Specifically, both the first magnetic suction member 143 and the second magnetic suction member 311 are magnets.

[0041] In summary, the fireworks display drone provided by this invention, through the cooperation of a lifting rail and a self-weight-lowering lifting sliding frame, allows fireworks with downward-facing nozzles to automatically slide down after the drone leaves the ground, increasing the vertical distance from the drone body to reduce the risk of burns and eliminating lateral center of gravity shift caused by horizontal extension, thus maintaining center of gravity stability before takeoff and after landing. Before takeoff, the bottom of the fireworks contacts the takeoff point to form an additional support point, reducing the probability of tipping over. During landing, the bottom of the fireworks contacts the landing point before the main landing frame to provide cushioning, and continues to maintain contact after landing to form auxiliary support, further reducing the risk of tipping over.
