Abstract

La présente invention se rapporte à une structure de charnière à charge élevée destinée à un dispositif d'affichage de type repliable, la structure de charnière étant installée dans la partie centrale qui est pliée dans un dispositif d'affichage pliable. Selon la structure de charnière, une butée libre peut être mise en œuvre de telle sorte qu'un état plié d'un dispositif d'affichage tel qu'un téléphone intelligent, un ordinateur portable, une tablette, etc. pourvu de deux panneaux puisse être maintenu par l'élasticité d'un ressort, et un ressort hélicoïdal de compression est conçu pour être inséré dans un arbre et agencé dans chacune des plaques reliées qui tournent l'une par rapport à l'autre de telle sorte qu'un espace cylindrique vide dans lequel un ressort est inséré ne soit pas nécessaire et qu'un ressort présentant un grand diamètre puisse être utilisé.
