Abstract

La présente invention concerne un ensemble de limitation, un mécanisme de connexion coulissant et un dispositif électronique pliable. Le dispositif électronique comprend deux coques reliées de manière rotative ; un ensemble écran souple recouvrant les deux coques, les bords de l'ensemble écran souple étant respectivement liés aux deux coques ; et un ensemble de limitation relié de manière fixe à l'ensemble écran souple, relié de manière coulissante aux deux coques, et configuré pour limiter l'ensemble le déplacement de l'écran souple et de la coque dans une première direction, la première direction étant perpendiculaire au plan où se trouve la coque ou l'ensemble écran souple. En concevant le mécanisme de connexion coulissant, la présente invention permet d'obtenir un coulissement libre au moyen d'un mouvement en couches avec l'écran souple. De plus, le mécanisme de bloc coulissant est limité dans la direction de l'axe Z au moyen de la structure d'une rainure coulissante, de façon à limiter le déplacement de l'ensemble écran souple dans la direction de liaison, ce qui permet de résoudre le renflement de l'écran souple.
