[0002] Traditional logistics relies on low labor costs, skilled workers, and insufficient annual output, and also depends on manual inspection. The civilian economy and logistics revolution: the manufacturing cycle of delivery drones has been shortened, costs reduced by 50%, making a "30-minute delivery" logistics network possible. Agricultural plant protection: large-scale production has reduced drone prices to the tens of thousands of yuan level, service costs have decreased by 70%, and farmland operation efficiency has increased 40 times. Infrastructure inspection: drones + AI inspection replace manual labor, reducing costs by 60%, improving safety by 100%, and expanding coverage by 5 times. The assembly process has a low rate of automation and a high proportion of labor costs. Drone assembly faces the challenges of "three highs and one precision": High precision: Hundreds of precision parts, manual assembly can easily introduce errors at the level of 0.01mm, directly affecting flight safety; High complexity: System integration involves multiple fields such as electronics, mechanics, and pneumatics, with hundreds of connecting harnesses; High reliability: Any tiny defect may lead to a crash; Lightweight: Simultaneously requiring structural strength and weight reduction (target weight reduction of 15-30%). On December 6, 2025, a search was conducted in the China Utility Model Public Database using "quick-release and docking and modular and UAV" as the abstract keywords and with the option to allow synonym expansion. CN219838709U relates to the field of unmanned aerial vehicle (UAV) frame technology and discloses a modular quick-release UAV frame, including a lower UAV frame. A quick-release hinge is provided at one end of the lower UAV frame, and an upper UAV frame is located above the quick-release hinge. The hinged portion of the upper UAV frame is detachably connected to the hinged end of the quick-release hinge, and the other end of the lower UAV frame is fixed in a slot-type plug-in manner. This utility model allows for the rapid switching of the lower fuselage to transform into different sizes and for different purposes, enabling the sharing of most or expensive electronic equipment across different aircraft. The upper fuselage module and the lower fuselage frame achieve rapid merging and separation through quick-release interfaces and integrated docking plugs.

[0003] CN219838709U belongs to the field of unmanned aerial vehicle (UAV) technology, specifically a streamlined coaxial multi-rotor UAV with quick disassembly. Addressing the problems of difficult disassembly and low stability during flight in existing UAVs, this invention proposes the following solution: It includes an arm module, a fuselage module, an upper shell module, a landing gear module, and a flight control system. The fuselage module comprises a carbon fiber fuselage, internally housing a battery compartment, a control compartment, and a payload compartment. The battery compartment contains a power battery, and the flight control system is located within the control compartment. This invention is easy to assemble, with modular connections between components supporting tool-free assembly and disassembly. The fuselage module, arm module, and landing gear module are connected via quick-release mounting brackets, enabling rapid plug-and-play installation and disassembly. This facilitates transportation and rapid deployment during use and maintenance. Utility Model Content
