所述第二支撑骨架4-1的数量为3条及以上奇数，本例为7条。
所述弹片4-2为至少2组，，本例为3组，所述两外侧第二支撑骨架4-1上相对的2个弹片4-2为一组，弹片4-2带动第一支架5和第二支架6分别与第一壳体1和第二壳体2产生推力，使柔性屏12弯折部分两端始终受到适当拉伸力，以保持柔性屏12绷紧平整。
柔性屏终端折叠组件的零部件用螺丝组装完成，第一壳体1和第二壳体2完全外折时7条第二支撑骨架4-1截面可组成一个180°扇形，7条第二支撑骨架4-1上表面组成的柔性屏12支撑面宽度在弯折过程中保持不变，通过第一阻尼器7和第二阻尼器7-1提供的阻力来限定第一支撑体3和第三支撑体11的滑动来实现柔性屏12的展开角度，当第二支撑体4上表面弧形长度大于伸出第一壳体1的第一支撑体3和伸出第二壳体2的第三支撑体11组成的下表面弧形长度时为外折角度范围，如图12、图13所示；当第二支撑体4的上表面和第一支撑体3与第三支撑体11组成的下表面为水平状态时，没有折叠该组件，如图14所示；当第二支撑体4的上表面弧形长度小于伸出第一壳体1的第一支撑体3与伸出第二壳体2的第三支撑体11组成的下表面弧形长度时为内折角度范围，如图15所示；当折叠组件为水平的未折叠状态时，波浪形弹片8可以加强第二支撑体4上各个第二支撑骨架4-1的平整和第一壳体1及第二壳体2的水平支撑力，以保证柔性屏12的平整度，折叠过程中弹片4-2始终让第一支架5和第二支架6分别对第一壳体1和第二壳体2产生推力，使柔性屏12始终保持一定力度的绷紧，确保柔性屏12在折叠过程中保持平滑。
当然，以上是本发明的优选实施方式。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明基本原理的前提下，还可以做出若干改进和润饰， 这些改进和润饰也视为本发明的保护范围。
