Title
(EN) ROTARY SHAFT ASSEMBLY AND FOLDABLE SCREEN DEVICE
(FR) ENSEMBLE ARBRE ROTATIF ET DISPOSITIF D'ÉCRAN PLIABLE
(ZH) 转轴组件及折叠屏设备
Abstract
(EN) A rotary shaft assembly (10) and a foldable screen device (100). The rotary shaft assembly (10) passes through at least one door plate (102) made using a first electrical material, the first electrical material having a density lower than 1.70g/cm 3. A second electrical material is disposed at a position of the at least one door plate (102) close to an antenna (40). Conductive performance of the door plate (102) is enhanced while the impact of the door plate (102) on the radiation performance of the antenna (40) is eliminated or mitigated, such that the door plate (102) exhibits good conductive performance in a radiation area, and the mass production performance of the foldable screen device (100) is enhanced.
(FR) La présente invention concerne un ensemble arbre rotatif (10) et un dispositif d'écran pliable (100). L'ensemble arbre rotatif (10) traverse au moins une plaque de porte (102) fabriquée à l'aide d'un premier matériau électrique, le premier matériau électrique ayant une densité inférieure à 1,70g/cm 3. Un second matériau électrique est disposé à une position de ladite plaque de porte (102) à proximité d'une antenne (40). Les performances conductrices de la plaque de porte (102) sont améliorées tandis que l'impact de la plaque de porte (102) sur les performances de rayonnement de l'antenne (40) est éliminé ou atténué, de telle sorte que la plaque de porte (102) présente de bonnes performances conductrices dans une zone de rayonnement, et les performances de production de masse du dispositif d'écran pliable (100) sont améliorées.
(ZH) 一种转轴组件(10)及折叠屏设备(100),转轴组件(10)通过至少一个门板(102)采用第一电学材料制成,且第一电学材料的密度小于1.70g/cm 3,并通过在至少一个门板(102)靠近天线(40)的位置设置第二电学材料,能够在起到增强门板(102)的导电性能的作用的同时解决或减轻门板(102)对天线(40)的辐射性能的影响,使门板(102)在辐射区域内体现良好的导电性能,提高折叠屏设备(100)的可量产性能。
