Abstract

Un appareil de photographie comprend un module de caméra (20) et un module de boîtier (10). Le module de caméra (20) comprend un support de lentille (22) et au moins un barillet de lentille (21). Le module de boîtier (10) comprend une lentille transparente (12) et un boîtier (11) comprenant une structure creuse (111). Un ensemble joint d'étanchéité (30) est relié entre le support de lentille (22) et la structure creuse (111). L'ensemble joint d'étanchéité (30) comporte un anneau de charge (31) et un anneau d'étanchéité (32). L'ensemble joint d'étanchéité (30) est utilisé pour sceller le barillet de lentille (22) dans une cavité scellée délimitée par le support de lentille (21), la lentille transparente (12) et la structure creuse (111). La structure ci-dessus peut améliorer la qualité de photographie d'un appareil de photographie fonctionnant dans un environnement à humidité élevée et à haute température. Un dispositif à cardan et un véhicule aérien sans pilote sont également divulgués.
