Abstract

L'invention concerne un pied de support anti-collision de rotor de véhicule aérien sans pilote qui comporte un bras de machine (1) dont une extrémité est reliée de manière rotative à un bloc de liaison (2), l'extrémité du bloc de liaison (2) à l'écart de la liaison au bras de machine (1) étant pourvue d'une cavité concave (20), deux tiges anti-collision (200) étant reliées de manière rotative à l'intérieur de la cavité concave (20), chaque tige anti-collision (200) comprenant une section de liaison horizontale (201) reliée à la cavité concave (20) et une aiguille anti-collision souple (202) reliée obliquement à la section de connexion (201). Le pied comprend également un bloc de limitation (3), le bloc de limitation (3) étant utilisé pour effectuer une limitation lorsque les deux tiges anti-collision (200) sont écartées. Pendant l'utilisation, le bloc de connexion (2) est mis en rotation, les deux tiges anti-collision (200) sont séparés d'un certain angle, le bloc de limitation (3) et le bloc de liaison (2) bloquent et fixent les tiges anti-collision (200), de sorte que les tiges anti-collision (200) sont réparties de manière fixe sur deux côtés de l'extérieur d'un rotor, et le rotor est protégé contre un risque d'impact et d'endommagement lorsqu'un corps de machine tourne ou roule. La structure entière est simple et les coûts sont bas.
