Abstract

Cette invention concerne un barillet de serrure électronique anti-déverrouillage illégal ayant une propriété de roue libre, comprenant un manchon de barillet de serrure (101), un barillet de serrure avant (201) et un barillet électronique rotatif (301), ainsi qu'un élément de commande électronique, installés en séquence dans le manchon de barillet de serrure ; un ensemble tige de poussée est installé dans le barillet de serrure avant (201) ; l'élément de commande électronique est composé d'une bobine électromagnétique (401) et d'un bloc de serrage à noyau de fer ; l'extrémité arrière du barillet de serrure avant (201) présente une rainure de serrage avant (206) correspondant au bloc de serrage à noyau de fer et, lors de la rotation, le barillet de serrure avant (201) entraîne le bloc de serrage à noyau de fer dans la rainure de serrage avant (206) en une rotation conjuguée ; la bobine électromagnétique (401) est installée dans un trou d'installation de bobine (3012) dans le barillet électronique rotatif (301), et l'extrémité avant de l'élément de commande électronique a une rainure de serrage arrière (3011) correspondant au bloc de serrage à noyau de fer. Lorsque le bloc de serrage à noyau de fer est positionné dans la rainure de serrage arrière (3011), la rotation du bloc à noyau de fer entraîne la rainure de serrage arrière (3011) en une rotation conjuguée. Une clé insérée dans le barillet de serrure avant (201) entraîne l'ensemble tige de poussée à se déplacer, et le mouvement de l'ensemble tige de poussée pousse/entraîne le mouvement vers l'avant/vers l'arrière du bloc de serrage à noyau de fer et amène le bloc de serrage à noyau de fer à se déplacer vers une position simultanément dans la rainure de serrage avant (206) et dans la rainure de serrage arrière (3011), et/ou le mouvement de l'ensemble tige de poussée l'amène à se séparer ou entrer en contact avec le bloc de serrage à noyau de fer simultanément positionné dans la rainure de serrage avant (206) et la rainure de serrage arrière (3011), l'ensemble tige de poussée n'affectant pas le mouvement du bloc de serrage à noyau de fer après sa séparation ou sa mise en contact avec le bloc de serrage à noyau de fer. L'invention concerne en outre un procédé de commande pour le barillet de serrure électronique et un système ayant ledit barillet de serrure électronique.
