Abstract

La présente invention concerne un ensemble de pliage (3) et un dispositif électronique (100). Le dispositif électronique (100) comprend un appareil de pliage (10) et un écran d'affichage flexible (20) ; l'appareil de pliage (10) est utilisé pour porter l'écran d'affichage flexible (20) ; l'appareil de pliage (10) comprend une première coque (1), une seconde coque (2), et l'ensemble de pliage (3). Au moyen du mouvement de l'ensemble de pliage (3), la première coque (1) et la seconde coque (2) peuvent être relativement dépliées vers un état ouvert ou relativement pliées vers un état fermé. L'ensemble de pliage (3) comprend un arbre principal (31), des premiers cadres de fixation (321), des premiers bras oscillants (322), des seconds cadres de fixation (324), des seconds bras oscillants (325) et des blocs d'arrêt (327). Lorsque la première coque (1) et la seconde coque (2) sont à l'état ouvert, les blocs d'arrêt (327) ont un effet d'arrêt sur les premiers bras oscillants (322) et les seconds bras oscillants (325), de sorte qu'un angle inclus entre la première coque (1) et la seconde coque (2) ne dépasse pas une valeur prédéfinie, empêchant ainsi l'appareil de pliage (10) d'être excessivement plié, empêchant l'écran d'affichage flexible (20) d'être excessivement tiré, et prolongeant la durée de vie de l'écran d'affichage flexible (20). En outre, grâce à la conception d'une structure d'adaptation des composants de l'ensemble de pliage (3), la stabilité globale d'une structure d'adaptation des arrêts est améliorée, de sorte que l'action d'arrêt est plus fiable.
