Abstract

La présente demande concerne un appareil de pliage et un dispositif électronique. L'appareil de pliage peut comprendre un ensemble charnière, un élément de raccordement, un élément de liaison et un premier élément élastique, l'ensemble charnière et l'élément de raccordement étant raccordés au moyen de l'élément de liaison de manière rotative ; et l'élément de liaison comprenant une première extrémité et une seconde extrémité, qui sont raccordées l'une à l'autre, la première extrémité étant raccordée à l'ensemble charnière de manière rotative, et la seconde extrémité étant raccordée à l'élément de raccordement de manière coulissante. Au moins l'un de la seconde extrémité et de l'élément de raccordement coopère avec le premier élément élastique, de telle sorte que la seconde extrémité vient en butée contre l'élément de raccordement. Étant donné que la seconde extrémité vient en butée contre l'élément de raccordement sous l'action du premier élément élastique, une force de frottement de coulissement est générée entre la seconde extrémité et l'élément de raccordement lorsque la seconde extrémité coulisse par rapport à l'élément de liaison, de telle sorte qu'un amortissement pour empêcher la seconde extrémité de coulisser par rapport à l'élément de raccordement est généré. Ainsi, au moyen de l'appareil de pliage et du dispositif électronique décrits dans la présente demande, l'effet de vol stationnaire de l'appareil de pliage à n'importe quel angle est meilleur, ce qui permet d'assurer que le dispositif électronique est survolé à n'importe quel angle.
