Abstract

Un ensemble charnière (300), se rapportant au domaine technique des communications. L'ensemble charnière (300) est utilisé pour relier de manière rotative un premier corps de dispositif (100) et un second corps de dispositif (200) d'un dispositif électronique ; l'ensemble charnière (300) comprend une base (340), un premier bras oscillant synchrone (310) et un second bras oscillant synchrone (320) qui sont reliés de manière rotative à la base (340), et un mécanisme de synchronisation de liaison ; le premier bras oscillant synchrone (310) est relié au mécanisme de synchronisation de liaison au moyen d'une première structure hélicoïdale ; le second bras oscillant synchrone (320) est relié au mécanisme synchrone de liaison au moyen d'une seconde structure hélicoïdale ; à la fois le premier bras oscillant synchrone (310) et le second bras oscillant synchrone (320) peuvent tourner par rapport au mécanisme synchrone de liaison. Dans le processus durant lequel le dispositif électronique est commuté entre un état déplié et un état plié, le premier bras oscillant synchrone (310) tourne et entraîne ensuite le mécanisme synchrone de liaison en déplacement au moyen de la première structure hélicoïdale, et le mécanisme synchrone de liaison entraîne le second bras oscillant synchrone (320) en rotation au moyen de la seconde structure hélicoïdale ; ou, le second bras oscillant synchrone (320) tourne et entraîne ensuite le mécanisme synchrone de liaison en déplacement au moyen de la seconde structure hélicoïdale, et le mécanisme synchrone de liaison entraîne le premier bras oscillant synchrone (310) en rotation au moyen de la première structure hélicoïdale. Ainsi, le problème dans l'état de la technique associé dans lequel la stabilité des dispositifs électroniques pliables est médiocre peut être résolu. La présente invention concerne en outre un dispositif électronique.
