Abstract

L'invention concerne un composant de limitation, un mécanisme de liaison coulissant et un dispositif électronique pliable. Le dispositif électronique comprend : deux coques reliées de manière rotative l'une à l'autre; un composant d'écran flexible, le composant d'écran flexible recouvrant les deux coques, et un bord du composant d'écran flexible étant respectivement relié aux deux coques d'une manière de liaison; et un composant de limitation, le composant de limitation étant relié de manière fixe au composant d'écran flexible, le composant de limitation étant relié de manière coulissante aux deux coques, et le composant de limitation étant utilisé pour limiter le déplacement du composant d'écran flexible et des coques dans une première direction, la première direction étant perpendiculaire à un plan dans lequel se trouve(nt) les coques ou le composant d'écran flexible. Selon la présente invention, au moyen de la conception d'un mécanisme de liaison coulissant, un coulissement libre conjointement avec le mouvement décalé de couche par couche d'un écran flexible est réalisé; pendant ce temps, au moyen de la structure d'une rainure de coulissement, un mécanisme de bloc coulissant est limité verticalement dans une direction d'axe Z, limitant ainsi le déplacement d'un composant d'écran flexible dans une direction de fixation, et résolvant le problème de l'arret d'écran flexible.
