Abstract

La présente invention concerne un dispositif de nettoyage de capteur optique, comprenant un moteur électrique d'entraînement (101), un essuie-glace (102), un palier (103) et un ou plusieurs capteurs (104), le moteur électrique d'entraînement (101) étant relié à une bague externe du palier (103) au moyen d'un mécanisme de transmission (109); un boîtier externe de transmission de lumière de rotateur (105) est relié à la bague externe du palier (103); le boîtier externe de transmission de lumière de rotateur (105) recouvre le ou les capteurs (104); et l'essuie-glace (102) est disposé à l'extérieur d'une paroi externe du boîtier externe de transmission de lumière de rotateur (105). Lorsque le dispositif de nettoyage fonctionne, l'essuie-glace (102) est uniquement en contact avec le boîtier externe de transmission de lumière de rotateur (105) sans rayer les capteurs (104), ce qui permet d'améliorer l'effet de nettoyage et d'éviter l'usure de surface des capteurs (104). De plus, le boîtier externe agencé de manière externe protège les capteurs (104), et n'interfère pas avec le fonctionnement des capteurs (104) ou ne provoque pas un défaut de mauvaise identification, de telle sorte que le dispositif de nettoyage de capteur optique est particulièrement approprié pour des occasions d'application intelligentes, telles qu'un système d'aide au conducteur de véhicule ou un système d'entraînement sans pilote.
