Abstract
Description
Technical Field
[0001] This utility model relates to the field of drones, and in particular to a promotional performance drone with a quickly changeable shell. Background Technology
[0002] In the current field of promotional performances, drone shows, as an emerging and highly attractive form of display, are being used more and more widely. Existing drone show technology typically relies primarily on using lighting effects at night to create spectacular visual performances. This method involves mounting various lighting devices on drones to create dazzling patterns and dynamic effects in the night sky to attract the audience's attention.
[0003] However, existing drone performance technology has significant problems. On the one hand, relying on light for performances is costly. Nighttime drone performances typically require a large number of drones arranged in an array to create a complete visual effect, which significantly increases the costs of drone procurement, maintenance, and operation, resulting in high overall performance costs. At the same time, light shows require specific dark environments, which limits performances to nighttime, greatly restricting the time and location options for such performances.
[0004] On the other hand, existing drones have significant limitations in terms of site applicability. In smaller spaces, such as small shopping mall atriums or small event venues, the limited space makes it difficult for existing drones to conduct effective flight demonstrations or promotional activities. Furthermore, using drones in confined spaces such as indoors poses safety hazards. The high-speed rotating propellers of drones could potentially cause injury to people and property in the vicinity.
[0005] In summary, existing drone performance technologies have many limitations in terms of cost, application scenarios, and safety. Therefore, finding a new technical solution to address these issues and meet the needs of promotional performances in different scenarios is a technical problem that urgently needs to be solved by those skilled in the art.

[0020] like Figure 1 and Figure 2 As shown, a promotional performance drone with a rapidly changeable shell is described. The device mainly includes a rotor unmanned aerial vehicle 1, an upper shell 2, and a lower shell 3.
[0021] In this embodiment, the rotor unmanned aerial vehicle 1, as the core flight component, is connected to the upper shell 2 via a fixed column 21 at its upper part and to the power supply box 31 at its lower part to obtain power support to achieve flight function.
[0022] Upper outer shell 2: A fixing column 21 is located downwards in the middle of the interior to securely connect to the upper middle part of the rotorcraft 1, providing it with an upper support point. Four upper guide columns 5 are also provided inside, which are fixed to the corresponding four lower guide columns 6 inside the lower outer shell 3 by bolts, thus achieving connection with the lower outer shell 3. Furthermore, an air vent 4, consisting of multiple horizontally arranged air guide slots 41, is provided at a position opposite to the rotor of the rotorcraft 1 to guide the airflow generated by the rotor's operation.
[0023] Lower outer shell 3: A power supply box 31 is located in the upper middle part to supply power to the rotorcraft UAV 1. A switch 32 and a power port 33 are located in the middle of the exterior, which are connected to the power supply box 31 respectively. The one-way insertion device inside the power port 33 can prevent the cable from falling off. A pair of landing gears 34 are arranged at the bottom to provide support during the take-off and landing of the UAV.
