- connection area 304 between the fixing block 13 and the reinforcing plate 50 can be fixed by welding. It should be understood that the present application is not limited to any welding process.
- the traction reinforcing plate drives the flexible screen assembly to move, so that the flexible screen assembly is in a free state during the folding process.
- the upper and lower limits of the slider mechanism are realized in the Z-axis direction, thereby limiting the position of the flexible screen assembly in the bonding direction, and solving the problem of screen arching.
- the setting of the limit component can improve the arching of the flexible screen component during bending. It should be understood that when the flexible screen assembly is arched, a part of the area close to the bent portion of the flexible screen assembly will be arched. Therefore, when setting each group of limit components, a different number can be used, such as one or more (two or more) to improve the arching of the flexible screen component.
- the “fixed connection” mentioned in this application can be understood as fixing the components through various methods such as glue dispensing and welding, and the “sliding connection” can be understood as meaning that the components are not fixed through various methods such as glue dispensing and welding.

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.
