具体实施方式
参照附图。本发明所提供的半自动内折柔性屏移动终端铰链，包括中部U形外罩3、左支撑架1、右支撑架2。如图1、2、14所示，左支撑架1、右支撑架2均包括有连接臂10、20，并通过连接臂10、20和U形外罩3转动连接，如图15、16所示，左支撑架1和连接臂10、右支撑架2和连接臂20均可为一体的部件；在左支撑架1、右支撑架2和U形外罩3上连接可折和展开的柔性屏支撑板，所述柔性屏支撑板处在铰链的内侧，在铰链处于打开展平状态时提供对柔性屏300的支撑，在铰链处于折拢状态下提供收纳柔性屏弯曲部位的空间301。
所述柔性屏支撑板由可转动的第一左支撑板51、第二左支撑板52、第一右支撑板61、第二右支撑板62组成；第一左支撑板51的内端和第二左支撑板52的外端转动连接，其转轴 50和U形外罩3的左上侧连接而获得支撑；第一右支撑板61的内端和第二右支撑板62的外端转动连接，其转轴60和U形外罩3的右上侧连接而获得支撑；第一左支撑板51的外端、第二左支撑板52的内端、第一右支撑板61的外端、第二右支撑板62的内端均为自由端，第二左支撑板52和第二右支撑板62在U形外罩3提供的空间30中分别以转轴50、60为轴转动，所述第一左支撑板51的外端和第一右支撑板61的外端分别和左支撑架1、右支撑架2活动连接，并在它们之间设置所述活动的导向机构。所述导向机构为设置在左支撑架1和右支撑架2上的导向槽12、22以及处在第一左支撑板51、第一右支撑板61的导向销或导向轴510、610，且左支撑架1和右支撑架2上的导向槽12、22对称设置。
第一左支撑板51及第二左支撑板52与它们的转轴50活动连接，第一左支撑板51设置有以转轴50为支点的扳动和支撑第二左支撑板52的杠杆短臂511，第一右支撑板61及第二右支撑板62与它们的转轴60活动连接，第一右支撑板61设置有以转轴60为支点的扳动和支撑第二右支撑板52的杠杆短臂611。
如图17、18、19所示，所述转轴50、60上还可设置扭簧53、63，扭簧53、63的一端抵靠U形外罩3上，另一端分别与第二左支撑板52和第二右支撑板62连接，在第二左支撑板52和第二右支撑板62失去短臂511、611支撑时，起到助力作用，使第二左支撑板52和第二右支撑板62快速向U形外罩3底部转动，而提高工作的灵敏度，快速形成所述空间301。
在铰链折拢过程中，第一左支撑板51和第一右支撑板61能以转轴50和60为轴转动，同时，左支撑架1和右支撑架2转至U形外罩3的上方，而转轴50处在U形外罩3的左上侧，转轴60处在U形外罩3的右上侧，从而第一左支撑板51和第一右支撑板61之间的间距扩大，而第二左支撑板52和第二右支撑板62失去支撑后自动转动，从而提供较大的空间301。而在铰链打开展平过程中，由于支撑第二左支撑板52和第二右支撑板62的为短臂511、611，因此打开展平的操作会非常轻松。
左支撑架1和右支撑架2的内侧端也即连接臂10、20分别与安装在U形外罩上的同步机构连接而实现与U形外罩的转动连接，使得左支撑架1和右支撑架2能以U形外罩连接和支撑结构而同步反向转动。所述同步机构可采用齿轮机构，所述齿轮机构可包括依次啮合的齿轮71、72、73、74。齿轮的参数根据铰链打开的动作设计要求，可采用对称式或不对称式。 齿轮71和齿轮74分别和连接臂10、20连接。所述U形外罩3的端部设置安装腔31，同步机构安装在安装腔31中，同步机构也可有外壳。左支撑架1和右支撑架2的转轴13、23即为齿轮71、74的轴。
所述左支撑架1和U形外罩3之间、右支撑架2和U形外罩3之间设置有扭力机构，提供铰链的半自动打开和折拢功能。即在打开或折拢操作的开始阶段需要手动操作，此时，扭力机构中的弹簧被压缩而蓄能，在打开或折拢到一定角度时，经过临界状态，弹簧由蓄能转为释能而自动打开或折拢。
所述扭力机构包括转动的扭力杆41、滑动件42和弹簧43，所述扭力杆41的一端和U形外罩3转动连接，另一端和滑动件42转动连接，滑动件42处在左支撑架1或右支撑架2的孔11、21中并和左支撑架1或右支撑架2的滑动连接，在滑动件42和左支撑架1之间，滑动件42和右支撑架2之间设置所述弹簧43，所述扭力杆41在铰链处在打开展平状态下及折拢状态下均呈倾斜状态，且在从一个倾斜状态转换到另一个倾斜状态时，所述滑动件42经过其向着压缩弹簧方向的运动极限位，使所述弹簧43经过临界状态，铰链工作从手动转为自动(弹簧驱动)，如图所示，在铰链打开展展平状态下，所述扭力杆是向着远离柔性屏的方向倾斜(一个状态状态)，在铰链状态从打开展平状态向折拢状态运动过程中，所述扭力杆会转换到向着柔性屏方向倾斜(另一个倾斜状态)。
应用上述铰链的移动终端，以手机为例，移动终端的左侧壳体101由柔性屏左侧主支撑板100及其外部的与其连接在一起的外部壳体组成，右侧壳体201由柔性屏右侧主支撑板200及其外部的与其连接在一起的外部壳体构成。所述柔性屏300铺设在所述铰链的内侧及柔性屏左侧主支撑板100和右侧主支撑板200上，所述左支撑架1和右支撑架2可以分别和移动终端的柔性屏左侧主支撑板100和右侧主支撑板200一体或分别为单独的部件并固定为一体。
U形外罩3具有结构骨架、收纳柔性屏支撑板、数据线400走线的多重功能，所述数据线400的中部处在U形外罩3内，数据线400的左右部分分别从U形外罩3穿入到左支撑架1、右支撑架2中再穿入移动终端的左侧壳体101和右侧壳体201内。所述数据线400分别从第一左支撑板和第二左支撑板的转轴50的下方并贴近该转轴50以及第一右支撑板和第二右支撑板的转轴60的下方并贴近该转轴60穿入移动终端的左侧壳体101和右侧壳体201内。
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。
