Abstract

La présente invention concerne une structure de verrouillage (100), une hélice (200), un dispositif d'alimentation (300), un ensemble d'alimentation et un véhicule aérien sans pilote (1000). La structure de verrouillage (100) comprend une base de montage (10) et un ensemble de verrouillage (20). L'ensemble de verrouillage (20) comprend un élément mobile (22) et un élément de butée (24). La base de montage (10) ou l'élément mobile (22) est utilisé(e) pour être mécaniquement accouplé(e) à l'hélice (200), et l'autre est utilisé(e) pour être accouplé(e) mécaniquement au dispositif d'alimentation (300). La base de montage (10) est pourvue d'une première partie de combinaison (12) et l'élément mobile (22) est pourvu d'une second partie de combinaison (222). L'élément de butée (24) est relié de façon mobile à l'élément mobile (22) et peut commuter entre une position de verrouillage et une position de déverrouillage. Lorsque l'élément de butée (24) est dans la position de verrouillage, l'élément de butée (24) vient en butée contre la première partie de combinaison (12) et/ou la seconde partie de combinaison (222) de telle sorte que la première partie de combinaison (12) et la seconde partie de combinaison (222) sont combinées et reliées l'une à l'autre. Lorsque l'élément de butée (24) est dans la position de déverrouillage, l'élément de butée (24) fournit un espace mobile destiné à la première partie de combinaison (12) et/ou la seconde partie de combinaison de telle sorte que la première partie de combinaison (12) et la seconde partie de combinaison (222) sont séparables l'une de l'autre.
