Even if the different rotation directions of the first propeller 22 and the second propeller 32 will not interfere with the fixed installation of the propellers. Therefore, the above-mentioned installation method of the multi-rotor unmanned aerial vehicle makes the installation operation of the propeller more convenient, and ensures the installation qualification rate of the propeller.

Abstract

La présente invention concerne un véhicule aérien sans pilote à rotors multiples comprenant un cadre (10), des rotors à rotation avant (20) et des rotors à rotation arrière (30). Chaque rotor à rotation avant (20) comprend un premier moteur (21), une première hélice (22) et un premier élément élastique (23). Chaque rotor à rotation arrière (30) comprend un second moteur (31), une seconde hélice (32) et un second élément élastique (33). Un siège d'hélice (221) de la première hélice (22) est pourvu d'une première partie de fixation (224), et la première hélice (22) peut coulisser dans la direction axiale de l'arbre rotatif du premier moteur (21), jusqu'à ce que le premier élément élastique (23) soit fixé à la première partie de fixation (224), de sorte que la première hélice (22) soit limitée dans la direction axiale de l'arbre rotatif du premier moteur (21). Un siège d'hélice (321) de la seconde hélice (32) est pourvu d'une seconde partie de fixation, et la seconde hélice (32) peut coulisser dans la direction axiale de l'arbre rotatif du second moteur (31), jusqu'à ce que le second élément élastique (33) soit fixé à la seconde partie de fixation, de sorte que la seconde hélice (32) soit limitée dans la direction axiale de l'arbre rotatif du second moteur (31). Le second moteur (31) entraîne, au moyen de la seconde partie de fixation, la seconde hélice (32) en rotation. Selon le véhicule aérien sans pilote à rotors multiples, les hélices peuvent être maintenues dans une connexion stable.
