所述中间安装架3对于所述左转动支架1和右转动支架2分别设置有固定支 架310、320，固定支架310、320分别设有处在两侧的圆弧形转动连接轨31、32；所述左转动支架1设有和两侧的圆弧形转动连接轨31相滑动连接配合的、处在它们之间的转动连接块11以及外接连接部12，右转动支架2设有和两侧的圆弧形转动连接轨32相滑动连接配合的、处在它们之间的转动连接块21以及外接连接部22，以利于中间安装架的让位空间的形成。外接连接部12、22分别用于和与其同步同向转动的部件连接，比如移动终端左侧机壳100和移动终端右侧机壳200；移动终端中的柔性屏左支撑板101和柔性屏右支撑板201可以分别连接到同侧的机壳上而和左转动支架1和右转动支架2同步同向转动，或者直接与左转动支架1和右转动支架2的外接连接部连接。铰链中的其它同步同向转动部件也可和外接连接部连接，比如扭力机构的转动部件。
所述左转动支架1和右转动支架2和中间安装架之间的转动连接结构也可以是连杆机构等。
所述铰链设置有同步机构，左转动支架1和右转动支架2还与同步机构连接，使左转动支架1和右转动支架2同步反向转动。
所述同步机构可采用齿啮合连接机构，可以是若干个齿轮连接而成或齿轮和齿条连接而成。在图1-4所示的实施例中，所述同步机构包括与左转动支架1的偏离轴线部位连接的第一齿条61和与右转动支架的偏离轴线部位连接的第二齿条62，第一齿条和第二齿条之间连接齿轮63，第一齿条61和第二齿条62分别位于中间齿轮63的前后侧，齿轮63的齿轮架、盖板设置在中间安装架3上，第一齿条61和第二齿条62的滑动导向轨311、321可分别设置在固定支架310、320上。
所述左转动支架1的偏离轴线部位和右转动支架的偏离轴线部位可分别设置连接销13、23，第一齿条61和第二齿条62分别设置与连接销13、23连接的滑槽64。
所述同步机构处在移动终端打开展平时柔性屏300覆盖的范围内，有助于内 折柔性屏移动终端的窄边框设计，所述同步机构可以设置在中间安装架3中。齿轮63平放，其轴线与左转动支架和右转动支架的轴线A1、A2垂直，有助于设置在柔性屏底部时，提供柔性屏弯曲时的让位同时满足减薄设计。齿条61、62和平放的齿轮63的位置低于中间安装架3的顶部。
在图10-12所示的实施例中，所述同步机构包括平放的中间齿轮7，其轴线与左转动支架和右转动支架的轴线A1、A2垂直，左转动支架和右转动支架通过齿轮71、72和所述中间齿轮7连接，中间齿轮7的位置低于中间安装架的顶部。
所述齿轮71、72的轴线与中间齿轮7的轴线垂直，分别位于中间齿轮7的左右侧，从而刚好在它们之间形成柔性屏弯曲的凹形让位空间。即有利于减薄设计又不妨碍齿轮的有效传动。
左转动支架1与所述齿轮71连接，但它们的轴线不重合；右转动支架2与所述齿轮72连接，但它们的轴线也不重合，这样，有助于间隙铰链和移动终端的厚度，有助于减小铰链的体积。左转动支架1的轴线A1与右转动支架的轴线A2相较于齿轮71、72的轴线更靠近中间安装架3的中线。
所述齿轮71的齿轮轴710的两端和齿轮72的齿轮轴720的两端均活动连接在固定支架310、320上。左转动支架1通过连杆73和齿轮71连接，连杆的一端和齿轮轴710的靠近左转动支架的这一侧固定连接，另一端通过导向销和导向槽的配合与左转动支架1连接，其中左转动支架1设置导向槽14，连杆73设置导向销730；右转动支架2通过连杆74和齿轮72连接，连杆74的一端和齿轮轴720的靠近右转动支架的这一侧固定连接，另一端通过导向销和导向槽的配合与右转动支架2连接，其中右转动支架2设置导向槽24，连杆74设置导向销740。
所述铰链对于左转动支架设置有提供转动阻力的第一扭力机构，对于右转动支架设置有提供转动阻力的第二扭力机构，以提高操作手感，还能进一步配合形成随时停止转动随时定位的功能。所述第一扭力机构和第二扭力机构处在移动终端打开展平时柔性屏300覆盖的范围内，可以设置中间安装架上。
所述第一扭力机构包括轴41、转动部件42和不转部件43，所述不转部件43被弹簧44压紧在转动部件42侧面而形成摩擦配合，第一扭力机构的转动部件42的转动轴线和左转动支架的轴线A1在同一直线上。
所述第二扭力机构包括轴51、转动部件52和不转部件53，所述不转部件53被弹簧54压紧在转动部件52侧面而形成摩擦配合，第二扭力机构的转动部件52的转动轴线和右转动支架的轴线A2在同一直线上.
所述中间安装架3上设置扭力机构的安装架6，所述轴41、51和扭力机构的安装架6连接，弹簧44、弹簧54分别和套在轴41、51上，不转部件43、53被防转结构限制而不能转动。
所述扭力结构的转动部件42、52设置有外接连接部45、55，用于和转动支架或柔性屏支撑板连接，而使得其也和柔性屏支撑板一起，作为与各自一侧的转动支架同步同向转动部件。不转部件43、53上或安装架6可设置所述转动部件转动的导向结构。
对于图10-12的同步机构实施方式，其可以结合扭力机构。对于齿轮轴710两侧中的不与连杆73连接的这一侧，正好能够和簧管81连接起到第一扭力机构的作用，对于齿轮轴720两侧中的不与连杆74连接的这一侧，正好能够和簧管82连接起到第二扭力机构的作用，而第一扭力机构的簧管81和第二扭力机构的簧管82可以从平放的中间齿轮7底部的中间安装架空间进行连接为整体而保持其不发生转动。
在所述移动终端进入到折拢状态时，处在柔性屏300和中间安装架3之间的所述左转动支架1及与左转动支架同步同向转动的部件(第一扭力机构的转动部件、左柔性屏支撑板101)和所述右转动支架及与右转动支架同步同向转动的部件(第二扭力机构的转动部件、右柔性屏支撑板201)分别反向转动至两侧，并且，左柔性屏支撑板和右柔性屏支撑板的内侧端102、202也转动至中间安装架内，而由中间安装架3的中间凹槽部区域30提供柔性屏300弯曲部位301的让 位。
左转动支架和右转动支架的轴线间的距离最佳为1～10mm。如图所示，以移动终端展平时的角度为0°时，从移动终端展平状态到折拢状态，左转动支架和右转动支架的转动角度分别为90°到95°，在该范围中，优选为超出90°，从而在折拢状态形成如8、9所示的三角关系，有利于对柔性屏弯曲的导向和柔顺。
以上所述仅为本发明的具体实施例，但本发明的结构特征并不局限于此，任何本领域的技术人员在本发明的领域内，所作的变化或修饰皆涵盖在本发明的保护范围之中。
