Abstract

La présente invention concerne une unité de caméra, un dispositif électronique, et un procédé d'utilisation du dispositif électronique. L'unité de caméra comprend un module de lentille, un mécanisme d'entraînement et un mécanisme de transmission ; le mécanisme d'entraînement comprend un moteur, un arbre d'entraînement et un bloc coulissant ; le mécanisme de transmission comprenant un premier ensemble de transmission pour entraîner le module de lentille de façon à se déplacer de façon linéaire et un second ensemble de transmission pour entraîner le module de lentille en rotation ; le second ensemble de transmission est connecté au module de lentille ; le premier ensemble de transmission comprend une tige de support, un premier élément magnétique et un second élément magnétique ; le premier élément magnétique est situé entre le module de lentille et le second élément magnétique et repousse le second élément magnétique ; le bloc coulissant est relié au second élément magnétique. Selon l'unité de caméra de la présente invention, dans le procédé selon lequel le premier élément magnétique entraîne le déplacement du module de lentille, le premier élément magnétique et le second élément magnétique ne seraient pas déformés ; de plus, les propriétés magnétiques du premier élément magnétique et du second élément magnétique ne seraient pas affaiblies en raison d'une utilisation à long terme, ce qui permet de prolonger la durée de vie de l'unité de caméra.
