展平电子设备100时，对电子设备100的第一框体21及第二框体23至少其中一个施加展平的力，使连接于第一框体21和第二框体23上的连接链节264朝相互远离的方向转动，通过联动机构29实现折叠装置24的同步展开。每一滑动部265随着折叠装置24的展平而向靠近中部铰节261的一侧拉动对应的传动件286，具体的，每一滑动部265上的连接柱2652滑动地拉动对应的传动件286的第一连接槽2861的内壁，使传动件286沿对应的转动孔2647的轴心线朝靠近中部铰节261的一侧转动，传动件286通过连接片287的连接柱2870在对应的传动件286的第二连接槽2865内滑动并转动而带动对应的滑动件284朝靠近中部铰节261的一侧滑动，每一导柱2645沿对应的导滑槽2842滑动。由于固定部282固定于中部铰节261，连接部283由可弯折的材料制成，因此，两个滑动件284一同向靠近中部铰节261的方向滑动的过程中，两个连 接部283均弹性复位而展平，从而使覆盖件28随折叠装置24的展平而展平，且覆盖件28一直贴合于可折弯部件26，以防止灰尘、杂物或强光进入电子设备100。
在对电子设备100的其他折弯方式中，还可以同时对第一框体21及第二框体23施加展平的力，第一框体21及第二框体23分别带动对应的支撑件264相对于支撑铰节262朝靠近柔性件30的一侧转动，通过联动机构29实现电子设备100的展平，且通过覆盖机构28对可折弯部件26进行覆盖，以防止灰尘、杂物或强光进入电子设备100。
折叠装置24完成弯折，柔性件30随折叠装置24实现弯折。如图11所示，弯折状态的支撑件264相背的两个侧面之间的沿可折弯部件26弯折外侧的距离也为L，即可折弯部件26的两个支撑件264位于弯折外侧的两个侧面之间在展平时的直线距离与在折叠时的沿可折弯部件26弯折外侧的距离相等，从而使覆盖于可折弯部件26上的柔性件30的可折弯区域31在弯折状态的宽度与展平状态的宽度相同，能防止柔性件30被挤压凸起或拉伸使屏幕损坏。可折弯部件26在弯折状态时，第一虚拟轴A1及第二虚拟轴A2均位于可折弯部件26的外部，优选的，第一虚拟轴A1及第二虚拟轴A2位于覆盖在可折弯部件26上的柔性件30的中性层上。本发明中的可折弯部件26的第一虚拟轴A1及第二虚拟轴A2在电子设备100折弯或展平时均位于所述中性层上，从而能保证柔性件30最大程度不受损。

滑动件284连接于传动件286的第一位置，滑动部265连接于传动件286的第二位置，第一位置不同于第二位置。传动件286在第二位置相对于滑动部265的传动距离小于传动件286在第一位置相对于滑动件284的传动距离。在可折弯部件26弯折时传动件286绕转轴290转动，第一位置相比第二位置更远离轴。所述传动距离是指一个元件带动另一个元件移动的距离，或者是一个元件受另一个元件带动所移动的距离。
传动件286的一端转动连接于支撑件264，滑动部265通过锁接件2866连接于传动件286的第二位置，滑动部265相对支撑件264滑动时，锁接件2866同时相对支撑件264及轴移动。可折弯部件26弯折时，锁接件2866朝向转轴290滑动，并同时相对支撑件264滑动。滑动件284通过连接柱2870连接于传动件286的第一位置，滑动件284相对支撑件264滑动时，连接柱2870同时相对支撑件264及转轴290移动。可折弯部件26弯折时，连接柱2870朝向转轴290滑动，并同时相对支撑件260滑动；可折弯部件26弯折时，连接柱2870相对转轴290滑动的距离大于锁接件2866相对转轴290滑动的距离。
