具体实施方式
为能进一步阐述本申请达成预定申请目的所采取的技术手段及功效，以下结合附图1-16及较佳实施方式，对本申请提供的折叠铰链结构及折叠终端设备的具体实施方式、结构、特征及其功效，作出如下详细说明。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中设置的元件。当一个元件被认为是“设置在”另一个元件，它可以是直接设置在另一个元件上或者可能同时存在居中设置的元件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1-2，是本申请实施例提供的一种折叠终端设备1000的结构示意图。所述折叠终端设备1000为折叠手机、折叠平板、折叠电脑、折叠笔记本、搭载有柔性折叠显示屏的终端等中的至少一种。在本申请中，所述折叠终端设备1000为折叠手机且其折叠方式为内折叠。折叠终端设备1000包括折叠铰链结构100、第一壳体200、第二壳体300和柔性屏(图中未示出)，折叠终端设备1000的相对两侧分别连接第一壳体200和第二壳体300，以使第一壳体200和第二壳体300通过折叠铰链结构100相对转动或背向转动，实现在展平状态和折叠状态之间切换。柔性屏设于第一壳体200、折叠铰链结构100和第二壳体300上。柔性屏能够用于显示信息并为用户提供交互界面，柔性屏可采用点胶等方式固定连接于第一壳体200和第二壳体300。第一壳体200和第二壳体300可以分别形成安装空间，以用于安装折叠终端设备1000的电路板、电池、受话器、扬声器、摄像头等电子元器件。其中，电路板可以集成折叠终端设备1000的主控制器、存储单元、天线模块、电源管理模块等电子元器件，电池则可以为柔性屏、电路板、受话器、扬声器、摄像头等电子元器件供电。
当第一壳体200和第二壳体300相向转动至相互层叠时(层叠指侧部可以无间隙贴合，或者间隔相对)，折叠终端设备1000处于折叠状态。反之，当第一壳体200和第二壳体300由相互层叠状态起，背向转动直至极限位置(即无法继续背向转动时，此时第一壳体200和第二壳体300展平)时，折叠终端设备1000处于展平状态。折叠终端设备1000在完全展平时，柔性屏被展平，此时折叠终端设备1000具有大屏显示的效果。在折叠状态时，第一壳体200叠设于第二壳体300，且柔性屏夹设于第一壳体200和第二壳体300之间。
请再次参阅图1，在本申请一实施方式中，所述折叠终端设备1000的一侧边上还设置有一按键400，所述按键400与所述折叠铰链结构100的驱动器52(见下文)电连接或信号连接。当单击或双击或长按或触摸所述按键400时，所述按键400向所述驱动器52发射开启信号，所述驱动器52收到开启信号，切换为自动打开模式，以使所述折叠终端设备1000自动打开。
在本申请一实施方式中，所述按键400还可以同时具有指纹解锁功能，单击或双击或长按或触摸所述按键400，可以一步实现所述折叠终端设备1000的自动打开和解锁。
在本申请一实施方式中，所述第一壳体200或所述第二壳体300上还设置有一外露的显示屏(图未示，且可为上述柔性屏)，所述显示屏上具有一解锁软件(图未示)。当滑动所述解锁软件时，所述折叠终端设备1000自动打开。
其中，所述折叠终端设备1000可以打开0°-180°。即，所述折叠终端设备1000可以展平或完全闭合。优选地，所述折叠终端设备1000可以打开30°，70°，150°及180°。当所述折叠终端设备1000打开70°-150°时，所述折叠终端设备1000可以在所需要的角度自由停止。当然，所述折叠终端设备1000在0°-180°中的任意一个角度均可以自由停止。

所述驱动器52还能够驱动所述卡扣53反向移动，将套设于第五凸轮4122和第六凸轮4222外的所述第三凸轮4121及所述第四凸轮4221释放。从而使所述第三凸轮4121 及所述第四凸轮4221可在第五凸轮4122和第六凸轮4222外自由转动，使所述第一凸轮411与所述第五凸轮4122抵接，所述第二凸轮421与所述第六凸轮4222抵接，从而切换为自动打开模式。并且，在完全打开时，所述第三凸轮4121及所述第四凸轮4221可刚好被第一凸轮411与第二凸轮421推转180°，从而可使所述驱动器52驱动卡扣53再次将所述第三凸轮4121及所述第四凸轮4221抵持。
更具体的，参阅图11，所述第三凸轮4121及所述第四凸轮4221相对的侧面设有卡槽4001。所述卡扣53穿设于所述支架51并与所述支架51滑动连接。所述驱动器52驱动所述卡扣53伸入所述卡槽4001中，从而使所述第三凸轮4121及所述第四凸轮4221不能自由转动，以相对固定于所述支架51上。

具体地，请参阅图4，所述第三子连接板23的一侧形成有一第五凸块231及一自所述第三子连接板23的一侧边向所述第三子连接板23内部凹陷形成的第三避让槽232。所述第四子连接板24的一侧形成有一第六凸块241及一自所述第四子连接板24的一侧边向所述第四子连接板24内部凹陷形成的第四避让槽242。所述第五凸块231收容在所述第四避让槽242内，所述第六凸块241收容在所述第三避让槽232内。当所述第三子连接板23及所述第四子连接板24打开或折叠时，所述第五凸块231能够在所述第四避让槽242内转动，所述第六凸块241能够在所述第三避让槽232内转动。
具体地，请参阅图3及图12，所述第二基座12包括一第五滑槽121及一第六滑槽122。所述第三子连接板23的远离所述第一基座11的一端还设置有一第三圆弧臂233，部分所述第三圆弧臂233凸出于所述第三子连接板23并与所述第四子连接板24接触。所述第四子连接板24的远离所述第一基座11的一端还设置有一第四圆弧臂243，部分所述第四圆弧臂243凸出于所述第四子连接板24并与所述第三子连接板23接触。所述第三圆弧臂233收容在所述第一第五滑槽121内。所述第四圆弧臂243收容在所述第六滑槽122内。所述第二基座12与所述第三子连接板23和第四子连接板24通过所述第五滑槽121、第六滑槽122、第三圆弧臂233及第四圆弧臂243转动且滑动连接在一起。在本实施方式中，所述第三圆弧臂233及所述第四圆弧臂243均呈圆弧状。
具体地，请参阅图13，所述第五滑槽121内设置有一第三圆弧滑道1211，所述第六滑槽122内设置有一第四圆弧滑道1221。所述第三圆弧臂233收容在所述第五滑槽121内且能够沿所述第三圆弧滑道1211滑动，所述第四圆弧臂243收容在所述第六滑槽122内且能够沿所述第四圆弧滑道1221滑动。当所述第三子连接板23及所述第四子连接板 24打开或折叠时，所述第三圆弧臂233及所述第四圆弧臂243分别沿所述第三圆弧滑道1211内及所述第四圆弧滑道1221滑动。
请再次参阅图3，所述第二基座12还包括两个导向孔123。所述切换组件50还包括两个固定在所述支架51远离第一凸轮组412及第二凸轮组422一端上的导向轴55。所述导向轴55用于限制所述支架51的运动方向及运动范围。两个所述导向轴55分别收容在两个所述导向孔123内且能够在所述导向孔123内滑动。
具体地，请参阅图14及图15，在所述折叠铰链结构100采用自动方式打开时，则单击或双击或长按或触摸所述按键400，使得所述驱动器52通电。所述驱动器52驱动所述卡扣53后移并脱离所述第三凸轮4121及所述第四凸轮4221，使所述第三凸轮4121及所述第四凸轮4221可自由转动。此时，所述第一弹性件433、第二弹性件435及所述第四弹性件437释放弹性力，将所述抵持板431、第一凸轮轴432及第二凸轮轴434向第一基座11方向推抵，使设于所述支架51上的第五凸轮4122及所述第六凸轮4222被带动，朝向所述第一凸轮411与第二凸轮421抵持，由于所述第五凸轮4122及所述第六凸轮4222上凸起连续下降至相邻的缺口，使得所述第一凸轮411与第二凸轮421在第五凸轮4122及所述第六凸轮4222的抵持下平滑旋转，由于连接摆杆组件30与连接板组件20滑动连接，使得被第一凸轮411与第二凸轮421带动旋转的连接摆杆组件30能够带动连接板组件20转动，从而将与连接板组件20连接的第一壳体200与第二壳体300打开。
同时，在连接摆杆组件30转动时，第一驱动齿轮61与第二驱动齿轮62在其之间的双数个所述同步齿轮63的啮合作用下同步旋转，保证第一子连接板21与第二子连接板22同步打开。旋转的所述第一子连接板21及所述第二子连接板22上的第一圆弧臂215及第二圆弧臂225分别在第三滑槽111及第四滑槽112内滑动，进而保证第一子连接板21及所述第二子连接板22打开时更稳定。
相应地，所述第一子连接板21及所述第二子连接板22打开带动第一壳体200及第二壳体300的打开，可进一步带动所述第三子连接板23上的第三圆弧臂233及所述第四子连接板24上的第四圆弧臂243分别在第五滑槽121及第六滑槽122内滑动，进而保证第一壳体200及第二壳体300打开时两侧的稳定。
具体地，自动打开所述折叠铰链结构100时，所述第一凸轮411与第二凸轮421转动的运动曲线可以参考图15。由图中可以看出，所述第一凸轮411与第二凸轮421的运动轨迹是不变的，沿第五凸轮4122及第六凸轮4222内凸起与相邻的缺口之间连续下降的缺口连续旋转的，且第三凸轮4121及第四凸轮4221是自由运动的，第一凸轮411与第二凸轮421的运动是与第五凸轮4122及第六凸轮4222上的凸起与相邻的缺口之间的坡度息息相关的。
具体地，请参阅图14及图16，在所述折叠铰链结构100采用手动方式打开时，所述驱动器52不通电，所述卡扣53卡持在所述卡槽4001中，所述第三凸轮4121及所述第四凸轮4221不能自由转动。此时，手动给所述折叠铰链结构100一个打开的力，使第一凸轮411与第二凸轮421越过所述第三凸轮4121及所述第四凸轮4221上的凸起并处于凸起与相邻的缺口之间，然后，所述第一弹性件433、第二弹性件435及所述第四弹性件437释放弹性力，将所述抵持板431、第一凸轮轴432及第二凸轮轴434向第一基座11方向推抵，使设于所述支架51上的第三凸轮4121及所述第四凸轮4221被带动， 朝向所述第一凸轮411与第二凸轮421抵持，从而将与连接板组件20连接的第一壳体200与第二壳体300打开；由于所述第三凸轮4121及所述第四凸轮4221上凸起与相邻的缺口之间存在至少一个平台，在该平台上，所述第一凸轮411与第二凸轮421不会转动，使第一壳体200与第二壳体300被打开一个角度而不会继续开启，当在此给所述折叠铰链结构100一个打开的力后，第一凸轮411与第二凸轮421将越过所述平台继续打开，直至完全打开时，所述第一凸轮411与第二凸轮421处于第三凸轮4121及所述第四凸轮4221的缺口处。
其中，手动打开时，同步组件60、连接板组件20的运动与自动打开时相同，再次不再赘述。
具体地，手动打开所述折叠铰链结构100时，所述第一凸轮411与第二凸轮421转动的运动曲线可以参考图16。由图中可以看出，由于沿第三凸轮4121及第四凸轮4221内凸起与相邻的缺口之间存在平台，所述第一凸轮411与第二凸轮421的运动轨迹在平台处与自动打开时不一致，将保持一定角度而不继续打开，第一凸轮411与第二凸轮421的运动是与第三凸轮4121及第四凸轮4221上的凸起与相邻的缺口之间的平台的数量息息相关的。
本申请提供的折叠铰链结构及折叠终端设备,所述折叠铰链结构中配置了设有自动凸轮及手动凸轮的切换组件、带有第一凸轮411与第一连接摆杆31、第二凸轮421与第二连接摆杆32的连接摆杆组件30、与连接摆杆组件30的一端滑动连接的连接板组件20、阻尼组件40及同步组件60，1)在切换组件通电情况下，所述折叠铰链结构能够自动打开，在切换组件不通电的情况下，所述折叠铰链结构能够手动打开或折叠，也即是说，本申请提供的折叠铰链结构及折叠终端设备能够同时支持自动及手动打开；2)所述折叠铰链结构能够打开180°，也即所述折叠铰链结构能够展平；3)通过一指纹按键或机械按键或一外露屏幕上的软件即可实现自动打开，不仅打开方式多样、操作简单，也可实现打开及解锁一步完成；4)只需要使得切换组件的卡扣固定住手动凸轮，使之不自由转动，即可从自动变为手动，转换速度快，可以实现高、低款型硬件共用；5)所述折叠铰链结构的应用场景较为广泛。
以上所述，仅是本申请的较佳实施方式而已，并非对本申请任何形式上的限制，虽然本申请已是较佳实施方式揭露如上，并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本申请技术方案内容，依据本申请的技术实质对以上实施方式所做的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
