AI Technical Summary
Technical Problem
The rotor structure of existing drones is non-foldable, resulting in a fixed overall size. This leads to a large space requirement for transportation and storage, and the landing gear lacks a cushioning structure, which affects the stable landing of the drone.
Method used
A foldable rotor structure was designed, which achieves rotor folding through elastic ropes and connectors, combined with support components to buffer landing impact force, and uses an arc-shaped plate of nylon and glass fiber composite material for buffering and stabilizing support.
Benefits of technology
It enables convenient folding of the rotor, reducing transportation and storage space requirements, while improving the landing stability and impact resistance of the drone.

Abstract
The unmanned aerial vehicle comprises an unmanned aerial vehicle body, a fixing assembly and a supporting assembly, a folding assembly is arranged at the top of the unmanned aerial vehicle body, and the fixing assembly is arranged in the middle of the folding assembly and used for fixing the fixing assembly. The supporting assembly is arranged at the bottom of the unmanned aerial vehicle body and used for assisting landing of the unmanned aerial vehicle body. The springs are triggered to be linked by pressing the pressing pieces, the rotor wing bodies rotate around the short rods to be attached to the long cylinders, the rotors are folded to be parallel to the fuselage in cooperation with elastic contraction of the elastic ropes, the storage size is reduced, carrying or transportation is convenient, a user only needs to press the pressing pieces with one finger, positioning pieces of the multiple rotors can be unlocked synchronously, and the user experience is improved. And step-by-step unlocking is achieved through the length difference of the connecting springs, and the storage operation time is shortened.
