Abstract

La présente invention concerne un dispositif de pliage, un ensemble boîtier et un dispositif électronique. Le dispositif de pliage comprend une base, un premier élément rotatif et un second élément rotatif, un premier élément de support et un second élément de support, et un mécanisme d'arrêt suspendu, le premier élément rotatif et le second élément rotatif étant tous deux reliés de manière rotative à la base ; une extrémité du premier élément de support étant reliée de manière rotative au premier élément rotatif, une extrémité du second élément de support étant reliée de manière rotative au second élément rotatif, et l'autre extrémité du premier élément de support et l'autre extrémité du second élément de support étant toutes deux reliées de manière coulissante et rotative à la base ; et le mécanisme d'arrêt suspendu comprenant un élément coulissant et un premier élément élastique, l'élément coulissant étant disposé sur la base, l'élément coulissant étant relié de manière rotative au premier élément rotatif et au second élément rotatif, et les extrémités opposées du premier élément élastique venant respectivement en butée contre l'élément coulissant et la base. Selon la présente invention, au moyen du premier élément rotatif et du second élément rotatif, le dispositif de pliage peut réaliser à la fois la fonction de pliage et de dépliage et la fonction d'arrêt suspendue, de telle sorte que le dispositif de pliage a moins de composants et a une structure simple et compacte, ce qui économise davantage d'espace et est propice au développement de la miniaturisation du dispositif de pliage.
