Abstract

L'invention concerne une structure anti-collision de rotor de véhicule aérien sans pilote, comprenant un bras de machine (1) et un rotor (2), une partie d'extrémité du bras de machine (1) étant pourvue d'un trou de montage vertical (10) pour le montage du rotor (2), une direction d'extension interne du bras de machine (1) étant pourvue d'un trou de passage de fil (11), le trou de passage de fil (11) étant en communication avec le trou de montage (10), une paroi latérale du trou de montage (10) étant pourvue d'une rainure de passage de fil (100), un côté du bras de machine (1) étant pourvu de manière rotative d'une tige anti-collision (12), une extrémité de la tige anti-collision (12) étant pourvue d'une rainure de positionnement (120), l'autre extrémité étant reliée de manière rotative à un pied de support anti-collision (121), le pied de support anti-collision (121) étant relié à la tige anti-collision (12) par l'intermédiaire d'une vis autobloquante (122), une surface latérale du bras de machine (1) étant pourvue d'une pluralité de premiers trous de vis mis en correspondance et positionnés avec la rainure de positionnement (120). Pendant l'utilisation, la tige anti-collision (12) est fixée avec les premiers trous de vis (non illustrés sur la figure) par l'intermédiaire de la rainure de positionnement (120) après être tournée de 180 degrés, et le pied de support anti-collision (121) est fixé avec la tige anti-collision (12) après être tourné vers l'extérieur du rotor (2), ce qui protège efficacement le rotor (2) lorsqu'un véhicule aérien sans pilote tourne ou roule. L'effet de protection est bon et la conception pliante est facile à ranger. La structure entière est simple et les coûts sont bas.
