在介绍本申请的技术方案之前，再详细介绍下相关技术中的技术问题。
折叠机构因其具有转动、折叠等功能，可应用于各种各样的领域中，例如门锁领域、车辆领域、机械制造领域、电子设备领域等等。折叠机构可通过其两个转动件分别连接一个结构件，从而实现两个结构件的转动。现以折叠机构应用于电子设备中的柔性折叠电子设备进行举例说明。
柔性折叠电子设备中的重要结构件之一：柔性显示屏是有机发光半导体(Organic Light-Emitting Diode，OLED)的一种重要应用技术，在近年来得到了重要的发展。与传统显示屏相比，柔性显示屏具有显著的优势，如其体积更加轻薄，功耗更低，而且得益于其可弯曲、具有柔韧性等特点，柔性显示屏的应用场景也越来越广泛，例如市场上已出现一些量产的基于柔性显示屏的折叠手机，主要分为柔性屏内折与柔性屏外折两种方案。其中，内折的优势在于壳体可有效保护柔性屏而降低外界撞击、磨损影响。外折的优势在于柔性屏弯折角不必过小，且半屏使用不必展开柔性屏。
然而柔性显示屏本身是厚度很薄的柔性发光层，在产品应用上，要依托于一定刚度的结构才能为用户方便使用。因此在结构上，柔性显示屏的弯折需要依托于刚性的壳体，两壳体通过折叠机构连接。柔性显示屏跟随壳体与折叠机构的变形，实现展开状态与折叠状态的变化。因此柔性显示屏的变形过程，即为可折叠机构的运动过程。
柔性折叠电子设备通常希望两个壳体同步转动，以减小柔性折叠电子设备打开与折叠时所需的时间，因此需要连接两个壳体的两个转动件同步转动，目前一般都采取齿轮啮合的方案来充当同步件，来实现左右转动件的同步运动。但由于齿轮尺寸小精度不容易控制，易导致齿轮虚位的存在，使得左右壳体同步效果较差。并且齿轮啮合单位面积低，很容易出现断齿、卡涩的问题，可靠性较低。
鉴于此，为了解决上述问题，本申请提供了一种折叠机构。请一并参考图1-图2，图1为本申请一实施方式中折叠机构的立体结构示意图。图2为图1的爆炸图。本实施方式提供了一种折叠机构1，包括两个转动件10，两个转轴20，以及滑动件30。一个所述转轴20连接于一个所述转动件10，另一个所述转轴20连接于另一个所述转动件10，且两个所述转轴20的轴向D相互平行。滑动件30与两个所述转轴20活动连接。一个所述转动件10带动与之连接的所述转轴20绕自身的轴向D转动能带动所述滑动件30沿所述轴向D移动，所述滑动件30沿所述轴向D移动能带动另一个所述转轴20绕自身的轴向D转动，进而带动另一个所述转动件10与一个所述转动件10同步做相反方向的运动。
折叠机构1(Foading mechanism)可应用于各种各样的结构中，例如门锁、车辆、各种机械设备、电子设备2等。可选地，本实施方式以及后文均以折叠机构1应用于电子设备2进行示意性说明，但这并不代表本实施方式的折叠机构1只能应用于电子设备2中，也可应用于其他结构中。进一步可选地，本实施方式提供的电子设备2包括但不限于折叠手机、平板电脑、笔记本电脑、掌上电脑、个人计算机(Personal Computer，PC)、个人数字助理(Personal Digital Assistant，PDA)、便携式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等移动终端，以及诸如数字TV、台式计算机等固定终端。当折叠机构1应用于折叠手机中时，是连接壳体并支撑柔性屏的结构单元，可减少壳体与柔性屏之间可能发生的错动。
两个转动件10分别用于连接不同的结构件，例如在折叠手机中两个转动件10可分别连接一个壳体，以实现当壳体转动时可带动转动件10转动，或者当转动件10转动时可带动壳体转动。本实施方式对两个转动件10的形状、结构、材质等参数并不进行限定，只要能使转动件10转动即可。
可选地，两个转动件10间隔设置，即两个转动件10之间具有间距，这样当两个转动件10转动时可降低相互碰撞的机率，还有利于其他结构件与转动件10的连接，还可为其他结构件预留装配空间。 当然在其他实施方式中两个转动件10也可相互抵接设置，本实施方式仅以两个转动件10间隔设置进行示意性说明。
可选地，两个转动件10呈轴对称设置，且每个转动件10包括相对设置的转动端11与连接端12，转动端11为转动件10中具有转动中心的端部，连接端12为转动件10与其他结构件(例如壳体)相连的端部。两个转动端11相较于两个连接端12相互靠近，即两个连接端12相较于两个连接端12相互远离，这样可便于两个转动件10分别连接其他结构件，也可便于其他结构件的结构设计。当然在其他实施方式中也可以为两个转动端11相较于两个连接端12相互远离，或者两个连接端12位于两个转动端11的同一侧。两个转动件10也可以为中心对称设置，或者同向设置等。本实施方式仅以两个转动端11相较于两个连接端12相互靠近进行示意性说明。
可选地，转动件10与其他结构件为滑动连接，即转动件10与其他结构件不仅可同步转动，转动件10还可相对其他结构件进行移动，以满足特定的需求。例如当电子设备2为U型柔性折叠屏手机时，转动件10与壳体无需滑动连接，当电子设备2为水滴型柔性折叠屏手机时，转动件10便可与壳体滑动连接，从而使壳体在转动的过程中可围设形成水滴形状。因此本实施方式提供的折叠机构1既可用于U型柔性折叠屏手机，也可用于水滴型柔性折叠屏手机，本实施方式在此并不进行限定。
转轴20为一种呈柱状的轴，主要起转动的作用。本实施方式对两个转轴20的形状、结构、材质等参数并不进行限定，只要能实现转动即可。每个转轴20连接一个转动件10，即一个转轴20连接于一个转动件10，另一个转轴20连接于另一个转动件10。由于转轴20与转动件10相互配合，因此当转轴20转动时便可带动转动件10同步转动，或者当转动件10转动时便可带动转轴20同步转动。值得注意的是，这里提及的“连接”可以理解为固定连接，也可以为可拆卸连接等其他连接方式。当转轴20固定连接转动件10时转轴20与转动件10为一体式结构，不过为了便于理解，人为地将转轴20与转动件10进行了不同的命名。如图2所示，当转轴20可拆卸连接转动件10时，转动件10可利用其自身的连接孔13套设于转轴20上，并通过设计转轴20的形状与连接孔13的形状，实现转轴20与转动件10的同步转动，便于折叠机构1的装配。可选地，本实施方式仅以转轴20可拆卸连接转动件10进行示意性说明，至于转轴20与转动件10的具体结构，本申请将在后文进行详细说明。另外，两个转轴20的轴向D相互平行，为后续折叠机构1的运动提供基础，防止折叠机构1在运动过程中出现卡死等问题。
可选地，两个转轴20间隔设置，可避免两个转轴20转动时相互碰撞，还可为其他结构件例如滑动件30预留装配空间。
滑动件30主要起导向移动的作用。本实施方式对滑动件30的形状、结构、材质等参数并不进行限定，只要能实现移动即可。本实施方式可将滑动件30与两个转轴20活动连接，实现滑动件30与转轴20的装配，便于后续滑动件30与转轴20进行配合，实现转动与移动的转。
可选地，至少部分滑动件30设于两个转轴20之间，利用两个转轴20之间的间隙来装配滑动件30，降低折叠机构1的尺寸与空间。这里提及的“至少部分滑动件30设于两个转轴20之间”可以理解为全部滑动件30均可以设于两个转轴20之间，或者部分滑动件30设于两个转轴20之间，而其余的滑动件30不设于两个转轴20之间。本实施方式以部分滑动件30设于两个转轴20之间进行示意性说明。
当至少部分滑动件30设于两个转轴20之间时，可使滑动件30与两个转轴20相互配合。可选地，滑动件30抵接于两个转轴20，这样可使转轴20的转动直接传给滑动件30，或者滑动件30的移动直接传给转轴20。
可选地，滑动件30的数量为一个，即一个滑动件30便可实现本实施方式的技术方案。当然在其他实施方式中也可设置多个滑动件30，本实施方式仅以一个滑动件30进行示意性说明。
本实施方式通过提供上述三种结构件，通过两个转动件10、两个转轴20、及滑动件30的相互配合便可实现折叠机构1的同步传动，此时折叠机构1可也称之为具有同步功能的折叠机构1。具体地，当两个转动件10中的任意一个相对滑动件30转动时便可带动与其相连的转轴20绕自身的轴向D同步转动(如图1中D1所示)。因此转动件10与转动件10的转动方向相同，均沿D1方向转动。而转动件10 之所以可以转动是由于与转动件10相连的结构件(例如壳体)转动从而带动转动件10进行转动，该结构件可绕转动件10的转动中心沿设定轨迹运动。转动的转轴20可与滑动件30相互配合将转轴20的转动转化为滑动件30的轴向D移动，使滑动件30沿转轴20的轴向D方向移动(如图1中D2所示)，滑动件30沿着转轴20的轴向D移动可以理解为滑动件30的移动方向平行于转轴20的轴向D方向。如图1所示，转轴20的轴向D可以理解为转轴20的轴线21的延伸方向。
由于滑动件30两侧与两个转轴20配合，因此当滑动件30移动时，滑动件30还可与另一侧的另一个转轴20配合将滑动件30的移动又转化为另一个转轴20绕自身的轴向D转动，从而使两个转轴20同步转动。当另一个转轴20转动时便可带动与其相连的另一个转动件10与一个转动件10同步做相反方向的运动，使两个转动件10同步转动(如图1中D1所示)。另一个转动件10转动时便可带动与另一个转动件10连接的结构件(例如壳体)进行转动，最终实现两个结构件的同步转动。至于转轴20与滑动件30如何配合以将转轴20的转动与滑动件30的移动相互转换，本申请将在下文进行详细介绍。
综上，本申请通过滑动件30便可实现两个转动件10的同步转动，当一个转轴20使滑动件30移动时，滑动件30可立刻使另一个转轴20转动。由于只利用滑动件30这一个部件来充当同步结构，避免了像相关技术中设置多个齿轮，且多个齿轮相互配合时易出现的虚位、断齿等问题，提高了传动的可靠性与同步效果。而且滑动件30的设置可减小两个转动件10之间的距离，从而减小弯折半径，当折叠机构1处于折叠状态时可减小两个转动件10之间的距离。
并且，本申请在同步时只需要两个转轴20分别与滑动件30组成的两对传动副，传动副的数量较少，结构简单，可减小折叠机构1的尺寸，降低折叠机构1占用的空间。另外折叠机构1只产生两次传动，提高了传动效率，还减小了累积公差间隙，能够有效降低转动空行程。
可选地，至少部分滑动件30设于两个转动件10的一侧。当然在其他实施方式中，调整转动件10与转轴20的连接方式，以及转动件10与转轴20的位置关系，可使得滑动件30设于两个转动件10之间。本实施方式对滑动件30与两个转动件10的位置关系并不进行限定。本实施方式及后文仅以滑动件30设于两个转动件10的一侧进行示意性说明。当滑动件30设于两个转动件10的一侧时，滑动件30沿转轴20的轴向D方向移动也可以理解为滑动件30沿靠近或远离转动件10的方向移动。
可选地，转动件10相对滑动件30既可顺时针转动，也可逆时针转动。
可选地，两个所述转动件10的转动方向相反使两个所述转动件10同向或背向运动，也可以理解为两个转轴20的转动方向相反，即另一个所述转轴20沿与一个所述转轴20转动方向相反的方向同步转动，从而带动另一个所述转动件10沿与一个所述转动件10转动方向相反的方向相对所述滑动件30转动。例如，当一个转动件10顺时针向外转动时，另一个转动件10逆时针向外转动。或者，当一个转动件10顺时针向内转动时，另一个转动件10逆时针向内转动。因此在同步转动的基础上还可使得折叠机构1展开与折叠，从而在不同的运动状态下改变折叠机构1的尺寸。
请一并参考图3-图8，图3为本申请一实施方式中折叠机构处于展开状态时的立体结构示意图。图4为图3的侧视图。图5为本申请一实施方式中折叠机构处于折叠状态时的立体结构示意图。图6为图5的侧视图。图7为本申请另一实施方式中折叠机构处于折叠状态时的立体结构示意图。图8为图7的侧视图。本实施方式中，所述折叠机构1具有所述转动件10的延伸方向平行于两个所述转轴20的排列方向时的展开状态、以及所述转动件10的延伸方向垂直于两个所述转轴20的排列方向时的折叠状态，当所述折叠机构1处于所述展开状态或所述折叠状态时，所述滑动件30与所述转动件10之间具有间隙。
折叠机构1在运动的过程中，即转动件10在转动的过程中具有两种特殊的状态：展开状态与折叠状态。展开状态指的是两个转动件10平行设置，且转动件10的延伸方向(如图3中D3所示)平行于两个转轴20的排列方向(如图3中D4所示)时的状态。转动件10的延伸方向可以理解为转动件10的转动端11至连接端12的方向，或者为转动件10的连接端12至转动端11的方向。如图3-图4所示，两个转轴20沿水平方向排列设置，因此当两个转动件10的延伸方向也为水平设置时，此时便可理解为折叠机构1的展开状态。折叠状态指的是两个转动件10平行设置，且转动件10的延伸方向(如图5与 图7中D3所示)垂直于两个转轴20的排列方向(如图5与图7中D4所示)时的状态。如图5-图8所示，两个转轴20沿水平方向排列设置，因此当两个转动件10的延伸方向垂直设置时，此时便可理解为折叠机构1的折叠状态。
当折叠机构1处于展开状态时，可使折叠机构1的面积最大，具有最大的展开面积。当折叠机构1处于折叠状态时，折叠机构1的面积最小，可以为展开面积的一半。因此当折叠机构1在展开状态与折叠状态之间转换时，折叠机构1、以及设于折叠机构1上的结构件的面积也在最大与最小之间不断转换。例如当柔性屏设于两个转动件10的一侧时，当折叠机构1处于展开状态时，此时柔性屏的显示面齐平设置，因此在折叠机构1一侧的显示面积是最大的。当折叠机构1处于折叠状态时，此时柔性屏在折叠机构1的带动下进行了弯折，因此在折叠机构1一侧的显示面积就会变小，可以为展开时的一半。
可选地，当柔性屏(图中未示出)设于两个转动件10的一侧时，例如设于图5-图8中转动件10的上方，转动件10的转动方向会影响柔性屏的折叠方式。例如在展开状态至折叠状态的过程中，若转动件10朝向靠近柔性屏的方向转动，会将两半的显示面相互靠近设置，此时可以理解为柔性屏的内折(如图5-图6所示)。若转动件10朝向远离柔性屏的方向转动，会将两半的显示面相互远离设置，此时可以理解为柔性屏的外折(如图7-图8所示)。
另外，请参考图3、图5、及图7，本实施方式中，当折叠机构1处于展开状态或折叠状态时，即折叠机构1处于极限状态时，滑动件30与转动件10之间具有间隙。换句话说，滑动件30运动到极限位置时与转动件10之间具有间隙，防止滑动件30与转动件10相互碰撞，提高折叠机构1的安全性。
可选地，当折叠机构1从展开状态至折叠状态的过程中，滑动件30沿靠近转动件10的方向移动；对应地，当折叠机构1从折叠状态至展开状态的过程中，滑动件30沿远离转动件10的方向移动。或者，当折叠机构1从展开状态至折叠状态的过程中，滑动件30沿远离转动件10的方向移动；对应地，当折叠机构1从折叠状态至展开状态的过程中，滑动件30沿靠近转动件10的方向移动。
请参考图9，图9为本申请一实施方式中滑动件与转轴的分解示意图。本实施方式中，所述转轴20的周侧设有第一配合部22，所述滑动件30的相对两侧均设有第二配合部31，所述第一配合部22与所述第二配合部31相配合，以将所述转轴20相对滑动件30的转动转换为所述滑动件30沿所述转轴20的轴向D方向的移动。以及，将所述滑动件30沿所述转轴20的轴向D方向的移动转换为所述转轴20相对滑动件30的转动。
为了实现转轴20的转动与滑动件30的移动相互进行转换，本申请提供了一种具体的实施方式。可在转轴20的周侧设置第一配合部22，即两个转轴20的周侧均设有第一配合部22。其中转轴20的周侧通常指的是转轴20在周向方向上的侧面。第一配合部22与转轴20可以为一体式结构，也可以为分体式结构。当第一配合部22与转轴20为一体式结构时，第一配合部22与转轴20可通过一道工序制备而成，为了便于理解，人为对第一配合部22与转轴20进行了不同的命名。当第一配合部22与转轴20为分体式结构时，第一配合部22与转轴20可分别形成，再通过各种方式装配到一起。本实施方式对第一配合部22与转轴20的配合关系并不进行限定。
由于至少部分滑动件30设于两个转轴20之间，因此可在滑动件30的相对两侧均可设置第二配合部31，用于和两侧的转轴20的第一配合部22进行配合，本实施方式仅示出了滑动件30的一侧设有第二配合部31，另一侧应当理解为也设有第二配合部31。可选地，滑动件30的相对两侧为滑动件30靠近两个转轴20的相对两侧，便于第一配合部22与第二配合部31进行配合。当然在其他实施方式中，滑动件30的相对两侧也可以为其他侧边，并利用其他结构件来使第一配合部22与第二配合部31进行配合，本实施方式仅以滑动件30的相对两侧为滑动件30靠近两个转轴20的相对两侧进行示意性说明。
第二配合部31与滑动件30可以为一体式结构，也可以为分体式结构。当第二配合部31与滑动件30为一体式结构时，第二配合部31与滑动件30可通过一道工序制备而成，为了便于理解，人为对第二配合部31与滑动件30进行了不同的命名。当第二配合部31与滑动件30为分体式结构时，第二配合部31与滑动件30可分别形成，再通过各种方式装配到一起。本实施方式对第二配合部31与滑动件30的 配合关系并不进行限定。
并且，本实施方式对第一配合部22与第二配合部31的结构、形状、材质等参数并不进行限定，只要第一配合部22与第二配合部31能相互配合实现移动与转动之间的转换即可。
可选地，第一配合部22与第二配合部31的数量可以为多个，多个第一配合部22与多个第二配合部31可提高传动精度，且配合面积大，机械可靠性高。进一步可选地，第一配合部22的数量与第二配合部31的数量可以相等，也可以不相等，本实施方式对此并不进行限定。
通过第一配合部22与配合部的设置，当两个转动件10中的任意一个相对滑动件30转动时便可带动与其相连的转轴20同步转动。转轴20转动时可带动设于转轴20上的第一配合部22进行转动。由于第一配合部22与滑动件30一侧的第二配合部31可相互配合，可将第一配合部22的转动转换为第二配合部31的移动，从而使滑动件30沿所述转轴20的轴向D方向移动。当滑动件30移动时，可带动滑动件30另一侧的第二配合部31移动，由于另一侧的第二配合部31可与另一个转轴20上的第一配合部22配合，以将第二配合部31的移动转换为第一配合部22的转动，实现另一个转轴20与另一个转动件10的同步转动。
另外，由于滑动件30两侧的第二配合部31的形状、结构、尺寸完全相同，因此一个转动件10与一个转轴20沿第一方向转动时，该第一配合部22与第二配合部31配合使滑动件30移动，而另一侧的的第二配合部31与另一个第一配合部22相配合便可使另一个转动件10与另一个转轴20沿与第一方向相反的方向转动，从而自动实现展开与折叠。
请再次参考图9-图11，图10为图9的侧视图。图11为本申请一实施方式中转轴的立体结构示意图。本实施方式中，所述第一配合部22与所述第二配合部31中的一者包括螺纹部220，所述第一配合部22与所述第二配合部31中的另一者包括螺纹槽310，且所述螺纹部220与所述螺纹槽310的延伸方向倾斜于所述转轴20的转动方向。
本申请还提供了一种第一配合部22与第二配合部31的具体实施方式，可利用螺纹部220与螺纹槽310来实现转动与移动的转换。其中螺纹部220指的是在转轴20的周侧或滑动件30的相对两侧凸出的部分，螺纹槽310指的是在转轴20的周侧或滑动件30的相对两侧凹陷的部分。第一配合部22包括螺纹部220或螺纹槽310，第二配合部31对应包括螺纹槽310或螺纹部220。具体地，当第一配合部22为螺纹部220时，第二配合部31为螺纹槽310。或者，当第一配合部22为螺纹槽310时，第二配合部31为螺纹部220。本实施方式仅以第一配合部22为螺纹部220，第二配合部31为螺纹槽310进行示意性说明。
另外，通过螺纹部220与螺纹槽310的设置，并使螺纹部220与螺纹槽310的延伸方向倾斜于所述转轴20的转动方向。如图10所示，转轴20与转动件10的转动方向可以理解为竖直转动，因此螺纹部220与螺纹槽310的延伸方向并不是竖直的，而是稍有倾斜，具体倾斜的角度可根据需求进行设计。当转动件10与转轴20转动时带动第一配合部22上的螺纹部220或螺纹槽310与滑动件30一侧的螺纹槽310或螺纹部220转动连接。由于螺纹槽310与螺纹部220是倾斜设置的，因此在转动的过程中螺纹部220会接触到螺纹槽310的槽壁从而对槽壁施加作用力，将竖直方向上的转动力的至少部分转换为水平方向上的移动力，使滑动件30移动。滑动件30的另一侧也同理进行配合，将移动力又转换回转动力，使另一个转轴20与另一个转动件10转动。
可选地，转轴20上的螺纹部220或螺纹槽310沿周向螺旋设置，以使转轴20在转动过程中螺纹部220与螺纹槽310能更好地进行配合。
可选地，如图11所示，螺纹部220包括间隔设置的多个子螺纹部2200，通过间隔设置的多个子螺纹部2200也可实现与螺纹槽310的配合，实现转动与移动的转换。并且将一个整体的螺纹部220分成多个子螺纹部2200还可降低制备难度，降低成本，降低折叠机构1的重量。
请再次参考图2与图9，本实施方式中，所述滑动件30的相对两侧均设有收容空间32，所述第二配合部31设于所述收容空间32的内壁上，部分所述转轴20设于所述收容空间32内。
本申请详细介绍了一种部分滑动件30设于两个转轴20之间的实施方式。在滑动件30的相对两侧均设置收容空间32，此时第二配合部31便可设在收容空间32的内壁上，此时便可将部分转轴20设于收容空间32内，从而使转轴20上的第一配合部22与内壁上的第二配合部31相配合。首先，将部分转轴20设于收容空间32内可减小转轴20、滑动件30、转轴20排列方向上的尺寸，从而使折叠机构1更紧凑。并且在滑动件30的内壁上设置第二配合部31，相较于在未开设收容空间32的侧壁92上设置第二配合部31，可提高第一配合部22与第二配合部31的接触面积，使第一配合部22与第二配合部31更好地进行配合，提高传动效果。
可选地，收容空间32的内壁的形状与转轴20周向的形状相匹配，从而进一步提高第一配合部22与第二配合部31的接触面积，使第一配合部22与第二配合部31更好地进行配合，提高传动效果。
可选地，收容空间32可以为收容槽或者收容孔。例如可在滑动件30靠近两个转轴20的相对两侧均开设收容槽，使转轴20设于收容槽内。或者在滑动件30靠近两个转轴20的邻侧开设收容孔，使转轴20贯穿收容孔。当转轴20贯穿收容孔时，还可利用收容孔的孔壁与转动件10配合，实现对滑动件30限位的作用。
上述内容详细介绍了转轴20与转动件10的连接关系与位置关系，下面将继续介绍转轴20与转动件10的连接关系，本实施方式以转轴20可拆卸连接转动件10时的具体结构进行介绍。
请一并参考图12，图12为本申请一实施方式中转轴与转动件的分解示意图。本实施方式中，所述转轴20包括相连接的第一部23与第二部24，所述第一部23的周侧设有所述第一配合部22，至少部分所述第二部24设有扁位结构240，所述转动件10具有连接孔13，所述转动件10通过所述连接孔13套设所述扁位结构240以使所述转动件10与所述转轴20同步转动。
本实施方式中的转轴20包括第一部23与第二部24。其中第一部23与第二部24构成转动件10，第一部23与第二部24可以为一体式结构，也可以为分体式结构。当第一部23与第二部24为一体式结构时，第一部23与第二部24可通过一道工序制备而成，为了便于理解，人为对第一部23与第二部24进行了不同的命名。当第一部23与第二部24为分体式结构时，第一部23与第二部24可分别形成，再通过各种方式装配到一起。本实施方式对第一部23与第二部24的配合关系并不进行限定。其中第一部23的周侧设有上述提及的第一配合部22，另外本实施方式对第一部23的形状、结构、尺寸并不进行限定，只要能使转轴20转动时第一配合部22可与第二配合部31进行配合即可。
至于第二部24的结构本实施方式具有一定的要求，可使至少部分第二部24设有扁位结构240。其中扁位结构240指的是第二部24的周向的形状若为圆形，则套设于第二部24的转动件10难与第二部24进行固定，因此可通过各种工艺(例如铣削加工)将圆形加工成其他形状从而在转动件10的转动过程中实现固定或者夹紧。因此扁位结构240可以为理解为形状为非圆形的结构。可选地，扁位结构240在周向的形状为正方形、长方形、椭圆形、五角星形等等。在此基础上可在转动件10上开设连接孔13，并使连接孔13的形状与扁位结构240的在周向的形状相匹配。例如若扁位结构240在周向的形状为正方形，则连接孔13的形状也对应为正方形。若扁位结构240在周向的形状为椭圆形，则连接孔13的形状也对应为椭圆形。这样便可使转动件10通过连接孔13套设扁位结构240上，以使转动件10转动时带动转轴20转动，或者转轴20转动带动转动件10转动。本实施方式仅以扁位结构240与连接孔13的形状为正方形进行示意性说明。
另外，上述提及的“至少部分第二部24设有扁位结构240”可以理解为全部第二部24均设有扁位结构240，或者部分第二部24上设有扁位结构240，而其余的第二部24上不设置扁位结构240。可选地，未设置扁位结构240的第二部24在周向上的形状仍可为圆形，从而便于将转轴20装配至其他结构件上并实现转动连接。本实施方式仅以部分第二部24上设有扁位结构240进行示意性说明。
请一并参考图13-图14，图13为本申请另一实施方式中滑动件与转轴的分解示意图。图14为图3中沿A-A方向中滑动件与转轴的部分截面示意图。本实施方式中所述第一配合部22上设有第一阻尼部25，所述第二配合部31上设有第二阻尼部33，当所述转动件10相对所述滑动件30转动到预设角度时， 所述第一阻尼部25与所述第二阻尼部33相抵接以用于当所述转动件10停止转动时，所述转动件10相对所述滑动件30保持静止状态。
从上述内容可知，当第一配合部22与第二配合部31相互配合时可实现转轴20的转动与滑动件30移动的转换。本实施方式可在第一配合部22上设置第一阻尼部25，在第二配合部31上设置第二阻尼部33，利用第一阻尼部25与第二阻尼部33相互配合来实现悬停的功能，此时的折叠机构1也可称之为具有一定阻尼的同步机构。其中，第一阻尼部25与第二阻尼部33为具有一定摩擦系数的结构，例如第一阻尼部25与第二阻尼部33中的至少一个可以由一种或多种耐磨材料制备而成。另外，第一配合部22与第一阻尼部25可以为一体式结构，也可以为分体式结构。当第一配合部22与第一阻尼部25为一体式结构时，第一配合部22与第一阻尼部25可通过一道工序制备而成，为了便于理解，人为对第一配合部22与第一阻尼部25进行了不同的命名。当第一配合部22与第一阻尼部25为分体式结构时，第一配合部22与第一阻尼部25可分别形成，再通过各种方式装配到一起。同理，第二配合部31与第二阻尼部33可以为一体式结构，也可以为分体式结构，本实施方式在此不再赘述。本实施方式对第一配合部22与第一阻尼部25、第二配合部31与第二阻尼部33的配合关系并不进行限定。
当施加外力使任意一个转动件10转动时可带动转轴20转动，转轴20转动时便可带动第一配合部22与第一阻尼部25转动。第一配合部22与第二配合部31可相互配合从而实现转动与移动的相互转换。但当转动件10相对滑动件30未转动预设角度时，此时第一阻尼部25一直在转动且未与第二阻尼部33接触。当转动件10相对滑动件30转动到某一个角度时，第一阻尼部25与第二阻尼部33开始一直保持接触状态。而当转动件10相对滑动件30转动预设角度时，若此时转动件10停止转动，第一阻尼部25与第二阻尼部33相互抵顶配合，第一阻尼部25与第二阻尼部33提供的摩擦力与阻尼力便可使转动件10相对滑动件30保持静止状态。其中静止状态指的是转动件10保持固定不动，不会由于转动件10自身的重力回落，实现悬停的功能，实现特定角度的限位，提高折叠机构1的稳定性。若想使转动件10继续转动，则可提供更大的外力，利用该外力的部分力来抵消阻尼力，而利用外力剩余的力来使转动件10转动。因此本实施方式并未限定若第一阻尼部25与第二阻尼部33相抵接时转动件10就一定会停止转动，只是说若转动件10在此时停止转动可实现悬停。若施加的力够大或继续施加力，转轴20与滑动件30可继续运动。另外，通过将第一阻尼部25与第二阻尼部33设于相互配合时的第一配合部22与第二配合部31上，可进一步降低折叠机构1的整体尺寸，降低折叠机构1所占用的空间大小。
具体地，当第一阻尼部25与第二阻尼部33相抵接时，第一阻尼部25与第二阻尼部33两者的相对干涉尺寸为δl。其中，如图14所示，相对干涉尺寸指的是第一阻尼部25背离第一配合部22一侧的表面与第二阻尼部33背离第二配合部31一侧的表面之间的垂直距离的最大值。此时第一阻尼部25与第二阻尼部33形成的限位扭力与阻尼力F 0与主要与δl相关，例如F 0＝f(δl)。当然F 0也与摩擦系数f等因素相关。若用户对转动件10弯折时其扭力F大于F 0时，转轴20可继续转动，折叠机构1可以继续弯折运动。若用户对转动件10弯折时的其扭力F不大于F 0时，转轴20则不能继续转动，折叠机构1处于相对稳固的状态，从而实现特定角度的限位。
可选地，上述提及的“预设角度”可以为0-90°范围内的任意角度，可使折叠机构1从展开状态至折叠状态的过程中的任意角度内实现悬停的功能。进一步可选地，预设角度可以为0°、15°、30°、45°、60°、90°等等。例如，转动件10相对滑动件30转动0°，即折叠机构1处于展开状态时实现悬停。或者转动件10相对滑动件30转动90°，即折叠机构1处于折叠状态时实现悬停。或者转动件10相对滑动件30转动45°，即折叠机构1处于展开状态至折叠状态的过程中实现悬停。另外，预设角度既可以为转动件10相对滑动件30顺时针转动的角度，也可以为转动件10相对滑动件30逆时针转动的角度。此时若以两个转动件10之间的夹角来看，则折叠机构1可以实现0-360°范围内的限位与悬停。当折叠机构1处于展开状态时，两个转动件10之间的夹角为180°。当折叠机构1处于折叠状态时，两个转动件10之间的夹角为0°或360°。
可选地，由于第一配合部22与第二配合部31为螺纹部220与螺纹槽310的组合。因此第一阻尼部 25与第二阻尼部33中的一者可设于螺纹部220上，另一者设于螺纹槽310的槽壁上。例如第一阻尼部25设于螺纹部220，第二阻尼部33设于螺纹槽310。或者，第一阻尼部25设于螺纹部220，第二阻尼部33设于螺纹槽310。进一步可选地，第一阻尼部25与第二阻尼部33中的一者包括阻尼片，另一者包括限位凸台。例如当第一阻尼部25为阻尼片时，第二阻尼部33为限位凸台。或者，第一阻尼部25为限位凸台，第二阻尼部33为阻尼片。综上，本实施方式的配合关系为螺纹部220与螺纹槽310的组合、以及阻尼片与限位凸台的组合。
本实施方式仅以第一配合部22为螺纹部220，第一阻尼部25为阻尼片，第二配合部31为螺纹槽310，第二阻尼部33为限位凸台进行示意性说明。进一步可选地，螺纹槽310的深度大于螺纹部220的高度，这样当转轴20相对滑动件30转动时，且未转动预设角度时，此时螺纹部220在螺纹槽310内转动且与螺纹槽310的槽壁相配合。但由于螺纹槽310的深度较大，因此螺纹部220上的阻尼片并未接触到螺纹槽310的底壁，并不会影响螺纹部220与螺纹槽310的配合，保证了转动的正常进行。但当转动件10相对滑动件30转动预设角度时，此时不仅螺纹部220与螺纹槽310相互抵接配合，阻尼片与限位凸台也会相互接触，从而实现悬停的功能。
请再次参考图14，本实施方式中，所述第一阻尼部25包括沿所述转轴20的轴向D间隔设置的多个第一子阻尼部250，所述第二阻尼部33包括沿所述转轴20的轴向D间隔设置的多个第二子阻尼部330，当所述转动件10相对所述滑动件30转动到所述预设角度时，所述第一子阻尼部250与所述第二子阻尼部330相抵接。
对于第一阻尼部25与第二阻尼部33来说，可分别包括多个子阻尼部，即多个第一子阻尼部250与多个第二阻尼部33，且多个子阻尼部沿转轴20的轴向D间隔设置。这样当转轴20转动时，多个第一子阻尼部250也会同步转动，当转动件10相对滑动件30未转动上述提及的预设角度时，多个第一子阻尼部250还未与多个第二子阻尼部330相抵接。当转动件10相对滑动件30转动上述提及的预设角度时，此时多个第一子阻尼部250便可与多个第二子阻尼部330相抵接进一步提高阻尼力，提高悬停效果，使折叠机构1更加稳固。
另外，上述提及的多个第一子阻尼部250与多个第二子阻尼部330相抵接指的并不是全部的第一子阻尼部250一直与全部的第二子阻尼部330相抵接，在滑动件30的移动过程中，第一子阻尼部250与第二子阻尼部330相抵接的数量会发生变化，只不过从整体来说是多个第一子阻尼部250与多个第二子阻尼部330相抵接。例如第一阻尼部25包括沿转轴20的轴向D间隔设置的5个第一子阻尼部250，第二阻尼部33包括沿转轴20的轴向D间隔设置的5个第二子阻尼部330，在第一次抵接时可以为5个第一子阻尼部250与5个第二子阻尼部330相抵接，在第二次相抵接时由于滑动件30移动了一段距离，可能会使得第一阻尼部25与第二阻尼部33错开设置，变为4个第一子阻尼部250与4个第二子阻尼部330相抵接。随着滑动件30的移动，相抵接的第一子阻尼部250与第二子阻尼部330的数量可能会减少，反之亦然。
请参考图15，图15为本申请另一实施方式中转轴的立体结构示意图。本实施方式中，所述第一阻尼部25与所述第二阻尼部33中的至少一者的数量为多个，且沿所述转轴20的周向间隔设置。
本实施方式可使第一阻尼部25的数量为多个，或者第二阻尼部33的数量为多个，或者同时使第一阻尼部25与第二阻尼部33的数量为多个，并且沿转轴20的轴向间隔设置。因此第一阻尼部25与第二阻尼部33不会同时接触，而是随着转动的持续进行一个个相接触。这样便会具有多个不同的预设角度，使其在多个不同的预设角度下相接触，从而实现悬停的效果。如图15所示，第一阻尼部25的数量为3个且分别间隔30°。当第一个第一阻尼部25在转动30°实现悬停时，第二个第一阻尼部25便可在转动60°实现悬停，第三个第一阻尼部25便可在转动90°实现悬停，从而使折叠机构1可在三种不同的角度下实现悬停。
请一并参考图16，图16为图14中的分解示意图。本实施方式中，所述第一子阻尼部250与所述第二子阻尼部330包括楔形面2511、弧形面2512、及抵接面2513，所述弧形面2512的两端分别连接所述 楔形面2511与所述抵接面2513；当所述转动件10相对所述滑动件30转动到所述预设角度时，两个所述抵接面2513相抵接。
对于第一子阻尼部250与所述第二子阻尼部330来说具有多个表面：楔形面2511、弧形面2512、及抵接面2513，其中楔形面2511与抵接面2513可连接第一配合部22或第二配合部31，弧形面2512的两端分别连接楔形面2511与抵接面2513。由楔形面2511、弧形面2512、及抵接面2513共同第一子阻尼部250与所述第二子阻尼部330的外表面。在转动件10相对滑动件30转动到某一角度时，第一子阻尼部250与第二子阻尼部330，此时可以为两个楔形面2511相接触，由于楔形面2511为一斜面，可使第一子阻尼部250更好地在第二子阻尼部330上运动，降低转动件10的转动难度。当转动件10继续转动时，两个弧形面2512可相互接触，此时可利用弧形面2512的弧度，降低第一子阻尼部250与第二子阻尼部330损坏的风险，提高第一子阻尼部250与第二子阻尼部330的使用寿命。随后当转动件10转动到预设角度时，此时两个抵接面2513相互抵接配合，实现悬停的功能。并且，若转动件10想回转，两个弧形面2512也可降低转动件的回转难度。
另外，第一子阻尼部250与第二子阻尼部330中的至少一者具有弹性，利用弹性来使第一子阻尼部250与第二子阻尼部330上的各个表面更好地进行接触，使转动件10的转动可以顺利进行。并且当第一阻尼部25与第二阻尼部33抵接后继续施加外力时，也可以使第一阻尼部25与第二阻尼部33分离，从而继续转动。
上述内容详细介绍了转动件10、转轴20、以及滑动件30的相关结构。接下来，本申请将继续介绍折叠机构1还可以存在的其他结构件。
请一并参考图17-图18，图17为本申请另一实施方式中折叠机构的立体结构示意图。图18为本申请一实施方式中第一装配件的立体结构示意图。本实施方式中，所述折叠机构1还包括第一装配件40，沿所述滑动件30的移动方向设于所述滑动件30的一侧，所述转轴20的一端转动连接所述第一装配件40。
第一装配件40在折叠机构1中起固定装配的作用，可将各种各样的结构件装配于第一装配件40上。本实施方式对于第一装配件40的形状、结构、材质等参数不进行限定，只要能实现装配即可。本实施方式可将转轴20的一端转动连接第一装配件40，即将转轴20安装至第一装配件40上，且转轴20相对第一装配件40可转动，从而使第一装配件40不影响转动的运动。
可选地，可在第一装配件40上开设第一转动空间41，转轴20的一端设于第一转动空间41内实现装配与转动。进一步可选地，第一转动空间41包括但不限于在第一装配件40相对两侧开设的第一转动孔，或在第一装配件40的一侧开设的转动槽。
另外，第一装配件40沿滑动件30的移动方向设于滑动件30的一侧，这样不仅可便于第一装配件40与转轴20之间的装配，还可便于后续在滑动件30与第一装配件40之间增设其他结构件，例如弹性件。可选地，第一装配件40设于滑动件30背离转动件10的一侧。
请一并参考图18-图20，图19为本申请又一实施方式中折叠机构的立体结构示意图。图20为图19的部分爆照图。本实施方式中，所述折叠机构还包括导轨50，所述导轨50的延伸方向与所述转轴20的轴向D相互平行，所述导轨50与所述滑动件30相互配合使所述滑动件30沿所述轴向D移动。
在第一装配件40的基础上，还可增设导轨50。其中导轨50主要起限位与导向移动的作用。可将导轨50连接至第一装配件40上。这里提及的“连接”包括但不限于固定连接或可拆卸连接等其他连接方式。当导轨50固定连接第一装配件40时，固定件与第一装配件40为一体式结构，不过为了便于理解，人为地将固定件与第一装配件40进行了不同的命名。当导轨50可拆卸连接第一装配件40时，如图19-图20所示，导轨50与第一装配件40可通过在导轨50与第一装配件40上开设螺钉孔52，再将螺钉51装设于螺钉孔52内以实现导轨50与第一装配件40的可拆卸连接。当然在其他实施方式中也可通过卡扣连接等方式实现可拆卸连接。本实施方式对导轨50的形状、结构、材质等参数并不进行限定，只要能起到限位的作用即可。
对于导轨50的位置来说，本实施方式可使至少部分导轨50设于两个转轴20之间，且同时设于至少部分滑动件30的一侧，从图19中可以看出，导轨50设于至少部分滑动件30的上方。这样当折叠机构1在运动时，转轴20与滑动件30配合使滑动件30沿着所述转轴20的轴向D方向移动，此时由于导轨50设于至少部分滑动件30的上方，即导轨50设于滑动件30垂直于滑动件30的移动方向的一侧，便可限制滑动件30朝向滑动件30至导轨50层叠的方向移动(如图19中D5所示)，即限制滑动件30向上移动。换句话说，避免滑动件30朝向远离两个转轴20的方向移动，防止滑动件30在移动时与转轴20分离。
上述提及的“至少部分导轨50设于两个转轴20之间”可以理解为，全部导轨50设于两个转轴20之间，或者部分导轨50设于两个转轴20之间，其余的导轨50设于两个转轴20之外。“导轨50设于至少部分滑动件30的一侧”可以理解为，导轨50设于全部滑动件30的一侧，或者导轨50设于部分滑动件30的一侧，而其余的滑动件30和导轨50之间具有其他位置关系。
另外，请再次参考图18与图20，本实施方式中，所述滑动件30的所述一侧设有滑动槽34，至少部分所述导轨50设于所述滑动槽34内，所述滑动槽34的延伸方向平行于所述滑动件30的移动方向。
本实施方式可在滑动件30靠近导轨50的一侧，即滑动件30的上侧开设滑动槽34，并使至少部分导轨50设于滑动槽34内。这样不仅可降低折叠机构1的整体厚度，并且当折叠机构1在运动时，由于所述滑动槽34的延伸方向平行于所述滑动件30的移动方向(如图20中D2所示)，因此导轨50不仅可以限制滑动件30朝向远离两个转轴20的方向移动，即竖直向上的移动。还可利用滑动槽34的槽壁来限制滑动件30在两个转轴20排列方向(如图20中D4所示)上的移动，即水平方向上的移动。使滑动件30只能在滑动槽34的延伸方向上滑动，以使滑动件30沿所述转轴20的轴向D方向移动，提高滑动件30的移动效果。因此本实施方式中的导轨50不仅可起到限位的作用，还可起到辅助移动的作用。
上述提及的“至少部分导轨50设于滑动槽34内”可以理解为，全部导轨50设于所述滑动槽34内，或者部分导轨50设于所述滑动槽34内。本实施方式在此并不进行限定。
可选地，如图18所示，第一装配件40与滑动件30开设滑动槽34的同一侧可设有配合槽42，使至少部分导轨50设于配合槽42与滑动槽34内，降低折叠机构1的整体厚度，简化导轨50的结构。
请一并参考图18，图21-图22，图21为本申请又一实施方式中折叠机构的立体结构示意图。图22为本申请一实施方式中滑动件的立体结构示意图。其中，图21为仰视看向折叠机构1时的立体结构示意图。本实施方式中，所述折叠机构1还包括连接所述导轨50的第一装配件40，以及第一弹性件60，所述转轴20转动连接于所述第一装配件40，所述第一弹性件60设于所述第一装配件40与所述滑动件30之间。
在第一装配件40的基础上，还可增设第一弹性件60。第一弹性件60具有一定的弹性。可选地，第一弹性件60包括但不限于螺旋弹簧、涡卷弹簧、板弹簧、碟形弹簧等。当然在其他实施方式中第一弹性件60也可以为其他具有弹性的物体，例如弹性泡棉、海绵、由各种高分子材料制成的弹性制品等等。本实施方式中第一弹性件60的数量可以为一个，也可以为多个。本实施方式仅以第一弹性件60的数量为一个进行示意性说明。
并且，每个第一弹性件60的至少部分设于第一装配件40与滑动件30之间。这样在折叠机构1的运动过程中，当转动件10与转轴20转动使滑动件30移动时，滑动件30会沿着所述转轴20的轴向D方向移动，即滑动件30会相应朝向远离或靠近第一装配件40的方向移动。因此在滑动件30的运动过程中便会带动第一弹性件60伸长或缩短，从而使第一弹性件60对应地产生拉伸力或压缩力。第一弹性件60同样也会给滑动件30一个反弹力。因此当转动件10在外力的作用下转动时，该反弹力会对转动件10的转动产生阻尼的效果，提高用户手感。并且随着滑动件30移动距离的增加，第一弹性件60的变形量增加，阻尼效果也会随之增加。另外，当转动件10上的外力撤销时，若没有其他固定结构，由于反弹力的存在，折叠机构1具有回复原状的趋势，从而实现自动复位的功能。
上述提及的“每个第一弹性件60的至少部分设于第一装配件40与滑动件30之间”指的是每个第一 弹性件60性的全部设于第一装配件40与滑动件30之间，或者每个第一弹性件60的部分设于第一装配件40与滑动件30之间，第一弹性件60其余的部分位于其他位置。
可选地，在本实施方式中当转动件10未转动时，即第一弹性件60的初始状态可以为平衡状态，第一弹性件60既未产生拉力，也未产生压力。当然在其他实施方式中若有其他结构件的配合，第一弹性件60在初始状态时也可以为压缩状态或者拉伸状态。本实施方式并不进行限定。
可选地，如图18所示，第一装配件40靠近滑动件30的一侧设有第一导向轴35，如图22所示，滑动件30靠近第一装配件40的一侧设有第二导向轴43，第一弹性件60套设第一导向轴35与第二导向轴43以实现定位装配，防止第一弹性件60在变形过程中沿非轴向D变形，提高变形的稳定性。
接下来将详细介绍一种每个第一弹性件60的部分设于第一装配件40与滑动件30之间的实施方式。请再次参考图21-图22，所述滑动件30靠近所述第一装配件40的一侧设有第一凹槽36，部分所述第一弹性件60设于所述第一凹槽36内。换句话说，第一凹槽36贯穿滑动件30靠近第一装配件40一侧的表面，即第一凹槽36的开口方向朝向第一装配件40，利用第一凹槽36来收容部分第一弹性件60，从而减小第一装配件40与滑动件30之间的距离，使折叠机构1更紧凑，降低折叠机构1的整体尺寸。
可选地，第二导向轴43可设于第一凹槽36的槽壁上，来实现对第一弹性件60的装配。
可选地，第一凹槽36可同时设于滑动件30背离导轨50的一侧，即第一凹槽36可同时贯穿滑动件30背离导轨50一侧的表面，第一凹槽36的开口除了朝向第一装配件40外，开口还可背离导轨50，降低第二弹性件80的装配难度。
请一并参考图23-图26，图23为本申请又一实施方式中折叠机构的立体结构示意图。图24为图23中另一个方向的立体结构示意图。图25为图23的部分爆炸图。图26为本申请一实施方式中第二装配件的立体结构示意图。其中，图23可以理解为俯视看向折叠机构1时的立体结构示意图。图24为仰视看向折叠机构1时的立体结构示意图。本实施方式中，所述折叠机构1还包括连接所述导轨50的第二装配件70，以及第二弹性件80，所述第二装配件70设于所述滑动件30背离所述第一装配件40的一侧，所述第二弹性件80设于所述第二装配件70与所述滑动件30之间。
在第一装配件40的基础上，还可增设第二装配件70与第二弹性件80。其中，第二装配件70在折叠机构1中起固定装配的作用，可将各种各样的结构件装配于第二装配件70上。本实施方式对于第二装配件70的形状、结构、材质等参数不进行限定，只要能实现装配即可。第二装配件70设于滑动件30背离第一装配件40的一侧，滑动件30设于第一装配件40与第二装配件70之间，第一装配件40与第二装配件70的排列方向平行于滑动件30的移动方向(如图23中D2所示)，这样不仅便于各种结构件的装配，还可利用第一装配件40与第二装配件70来对滑动件30的移动距离进行限位。
可选地，至少部分第二装配件70设于两个转动件10之间，使折叠机构1更紧凑，减小折叠机构1的尺寸大小。进一步可选地，转轴20可转动连接于第二装配件70。当然在其他实施方式中转轴20也可装配于其他部件上，本实施方式在此并不进行限定。
可选地，导轨50连接第一装配件40与第二装配件70，从而进一步提高导轨50的连接性能。这里提及的“连接”包括但不限于固定连接或可拆卸连接等其他连接方式。当导轨50固定连接第二装配件70时，固定件与第二装配件70为一体式结构，不过为了便于理解，人为地将固定件与第二装配件70进行了不同的命名。当导轨50可拆卸连接第二装配件70时，如图23与图25所示，导轨50与第二装配件70可通过在导轨50与第二装配件70上开设螺钉孔52，再将螺钉51装设于螺钉孔52内以实现导轨50与第二装配件70的可拆卸连接。当然在其他实施方式中也可通过卡扣连接等方式实现可拆卸连接。
对于第二弹性件80来说，第二弹性件80具有一定的弹性。可选地，第二弹性件80包括但不限于螺旋弹簧、涡卷弹簧、板弹簧、碟形弹簧等。当然在其他实施方式中第二弹性件80也可以为其他具有弹性的物体，例如弹性泡棉、海绵、由各种高分子材料制成的弹性制品等等。本实施方式中第二弹性件80的数量可以为一个，也可以为多个。本实施方式仅以第二弹性件80的数量为一个进行示意性说明。
并且，每个第二弹性件80的至少部分设于第二装配件70与滑动件30之间。这样在折叠机构1的 运动过程中，当转动件10与转轴20转动使滑动件30移动时，滑动件30会沿着所述转轴20的轴向D方向移动，即滑动件30会相应朝向靠近或远离第二装配件70的方向移动。因此在滑动件30的运动过程中便会带动第二弹性件80伸长或缩短，从而使第二弹性件80性对应地产生拉伸力或压缩力。第二弹性件80同样也会给滑动件30一个反弹力。因此当转动件10在外力的作用下转动时，该反弹力会对转动件10的转动产生阻尼的效果，提高用户手感。并且随着滑动件30移动距离的增加，第二弹性件80的变形量增加，阻尼效果也会随之增加。另外，当转动件10上的外力撤销时，若没有其他固定结构，由于反弹力的存在，折叠机构1具有回复原状的趋势，从而实现自动复位的功能。
上述提及的“每个第二弹性件80的至少部分设于第二装配件70与滑动件30之间”指的是每个第二弹性件80性的全部设于第二装配件70与滑动件30之间，或者每个第二弹性件80的部分设于第一装配件40与滑动件30之间，第二弹性件80其余的部分位于其他位置。
可选地，在本实施方式中当转动件10未转动时，即第二弹性件80的初始状态可以为平衡状态，第二弹性件80既未产生拉力，也未产生压力。当然在其他实施方式中若有其他结构件的配合，第二弹性件80在初始状态时也可以为压缩状态或者拉伸状态。本实施方式并不进行限定。
可选地，如图26所示，第二装配件70靠近滑动件30的一侧设有第三导向轴71，如图22所示，滑动件30靠近第二装配件70的一侧设有第四导向轴37，第二弹性件80套设第三导向轴71与第四导向轴37以实现定位装配，防止第二弹性件80在变形过程中沿非轴向D变形，提高变形的稳定性。
接下来将详细介绍一种每个第二弹性件80的部分设于第二装配件70与滑动件30之间的实施方式。
请再次参考图22与图24，本实施方式中所述滑动件30靠近所述第二装配件70的一侧设有第二凹槽38，部分所述第二弹性件80设于所述第二凹槽38内。换句话说，第二凹槽38贯穿滑动件30靠近第二装配件70一侧的表面，即第二凹槽38的开口方向朝向第二装配件70，利用第二凹槽38来收容部分第二弹性件80，从而减小第二装配件70与滑动件30之间的距离，使折叠机构1更紧凑，降低折叠机构1的整体尺寸。
可选地，第四导向轴37可设于第二凹槽38的槽壁上，来实现对第二弹性件80的装配。
可选地，第二凹槽38可同时设于滑动件30背离导轨50的一侧，即第二凹槽38可同时贯穿滑动件30背离导轨50一侧的表面，第二凹槽38的开口除了朝向第二装配件70外，开口还可背离导轨50，降低第二弹性件80的装配难度。
可选地，第一凹槽36与第二凹槽38间隔设置，即第一凹槽36与第二凹槽38之间可由滑动件30的部分来进行分隔，从而是设于第一凹槽36与第二凹槽38内的第一弹性件60与第二弹性件80互不影响。
本实施方式中，所述折叠机构1具有所述转动件10的延伸方向平行于两个所述转轴20的排列方向时的展开状态、以及所述转动件10的延伸方向垂直于两个所述转轴20的排列方向时的折叠状态，当所述折叠机构1处于所述展开状态或所述折叠状态时，所述第一弹性件60与所述第二弹性件80均处于压缩状态且弹性系数相同。
对于折叠机构1的展开状态与折叠状态由于本申请上文已进行了详细介绍，本实施方式在此不再赘述。从上述内容可知，折叠机构1还可包括第一装配件40，第二装配件70，第一弹性件60，以及第二弹性件80，并且第一弹性件60位于第一装配件40与滑动件30之间，第二弹性件80位于第二装配件70与滑动件30之间，并且在滑动件30未移动，及整个移动过程中，第一弹性件60与第二弹性件80会相应地发生形变，从而具有不同的形变状态。
上述提及的滑动件30的整个运动过程可以理解为折叠机构1从折叠状态至打开状态的过程，或者折叠机构1从打开状态至折叠状态的过程。本实施方式可使当所述折叠机构1处于所述展开状态或所述折叠状态时，所述第一弹性件60与所述第二弹性件80均处于压缩状态。也可以理解为，折叠机构1在整个运动过程中的开始阶段与结束阶段第一弹性件60与第二弹性件80均处于压缩状态，因此第一弹性件60与第二弹性件80在整个过程中均处于压缩状态。
并且由于上述内容已经提及滑动件30设于第一装配件40与第二装配件70之间，第一凹槽36与第二凹槽38设于滑动件30的相对两侧，第一弹性件60的一端设于第一凹槽36内，另一端设于第一装配件40上。第二弹性件80的一端属于第二凹槽38内，另一端设于第二装配件70上。所以至少部分第一弹性件60与至少部分第二弹性件80相背设置。这样的话，由于第一弹性件60与第二弹性件80始终处于压缩状态，因此第一弹性件60与第二弹性件80具有初始预紧力。例如第一弹性件60具有初始预紧力G 01，第二弹性件80具有初始预紧力G 02，因此两个弹性件对折叠机构1整体的阻尼力G 0为：G 0＝G - 01+G 02。
另外，由于折叠机构1在运动的过程中，也就是滑动件30移动的过程中会改变第一弹性件60与第二弹性件80的压缩力，即会改变第一弹性件60与第二弹性件80的预紧力。但由于第一弹性件60与第二弹性件80的弹性系数相同，因此第一弹性件60与第二弹性件80改变的力的大小相同，方向相反，导致了第一弹性件60与第二弹性件80改变后的预紧力之和恒为G 0。这样便可使折叠机构1运动全过程中均具有一定的阻尼，使其扭力稳定，用户在弯折时手感顺滑不松散，用的力始终相同，提高了用户弯折时的体验感。
上述内容提及了转动件10转动弯折时其扭力F与F 0的关系，本实施方式由于引入了第一弹性件60与第二弹性件80对折叠机构1整体的阻尼力G 0，此时若扭力F大于F 0与G 0之和，转轴20可继续转动，折叠机构1可继续弯折运动。若扭力F不大于F 0与G 0之和，则转轴20不能继续转动，折叠机构1处于相对稳固的状态，以实现在特定角度下的悬停与限位。
可选地，第一弹性件60的初始预紧力G 01与第二弹性件80具有初始预紧力G 02可以相同，也可以不同，本实施方式在此并不进行限定。
另外，请再次参考图24，本实施方式中，所述滑动件30沿所述转轴20的轴向D方向的移动极限行程小于所述第一弹性件60的最大形变量和所述第二弹性件80的最大形变量。
第一弹性件60与第二弹性件80除了具有上述初始预紧力的关系之外，本实施方式还可根据第一弹性件60与第二弹性件80的最大形变量，即极限行程来限制滑动件30的移动极限行程。由于每个弹性件的成分、材质、尺寸、工艺制备方法都不尽相同，因此每个弹性件均有自身的最大形变量。例如第一弹性件60具有第一极限行程m1，即达到第一弹性件60本身的最大形变量。第二弹性件80具有第二极限行程m2，即达到第二弹性件80本身的最大形变量。滑动件30在转轴20的轴向D(如图24中D2所示)移动时会带动第一弹性件60与第二弹性件80发生形变，会使其趋近于自身的极限行程，本实施方式可使滑动件30的移动极限行程小于第一极限行程与第二极限行程中的最小值，来使得滑动件30在移动时不会超出任何一个弹性件的极限行程，从而保证两个弹性件产生的阻尼力G 0保持不变，提高了阻尼力G 0的稳定性。
请参考图27，图27为本申请又一实施方式中折叠机构的部分立体结构示意图。本实施方式中，所述折叠机构1还包括旋转件100，转动连接于所述第一装配件40，所述旋转件100与所述转动10件均用于连接壳体，并能够所述壳体的转动下进行转动，所述旋转件100的转动中心线111与所述转轴20的轴线21重合或者具有间距。
在折叠机构1具有转动件10的基础上，还可增设旋转件100。旋转件100的主要作用与转动件10相同，也是起到转动、旋转的作用。旋转件100的旋转方向平行于转动件10的转动方向(如图30中D1所示)，因此可将旋转件100与转动件10共同连接于壳体上，与壳体配合运动，在壳体的带动下进行转动，提高壳体运动的稳定性。旋转件100可转动连接于第一装配件40上，即第一装配件40不仅可转动连接转轴20，从而转动连接转动件10，还可转动连接旋转件100，使转动件10与旋转件100都基于第一装配件40进行转动。从上述内容可知，转动件10转动时带动转轴20转动，转轴20转动时是绕着转轴20的轴线21转动。这里提及的轴线21的延伸方向便可理解为上述内容提及的转轴20的轴向D方向，两者实质上是一个意思。
旋转件100在第一装配件40上旋转时绕着转动中心线111旋转，这里提及的转动中心线111可以 为旋转件100本身的轴线，也可以为旋转件100套设在某个结构件上轴线，例如旋转件100套设轴套110，因此转动中心线111即为轴套110的轴线。对于轴线21与转动中心线111来说具有多种不同的位置关系，例如轴线21与转动中心线111可重合设置，即转动件10与旋转件100的转动轴心同心设置，换句话说转动件10与旋转件100同心运动，当转动件10与旋转件100转动相同角度时，不会产生位移偏差，此时可应用于U型的柔性折叠屏手机中。当轴线21与转动中心线111之间具有间距时，即转动件10与旋转件100的转动轴心不同心设置，换句话说转动件10与旋转件100偏心运动，当转动件10与旋转件100转动相同角度时，转动件10与旋转件100之间会产生位移偏差，此时可应用于水滴型的折叠屏手机中，通过转动件10控制壳体在转动过程中的方向，旋转件100控制折叠机构1与壳体设定点位的相对距离限制壳体径向方向的运动。本实施方式仅以轴线21与转动中心线111重合进行示意性说明。至于具体本实施方式应用于水滴型的柔性折叠屏手机时，折叠机构1与壳体是如何配合的，本实施方式在此不进行详细说明。
请一并参考图28-图29，图28为本申请一实施方式中旋转件、轴套、以及第一装配件的分解示意图。图29为本申请另一实施方式中旋转件与第一装配件的分解示意图。本实施方式中，所述折叠机构1还包括转动连接所述第一装配件40的轴套110，所述旋转件100套设所述轴套110；或者，所述第一装配件40与所述旋转件100中的一者设有旋转块120，所述第一装配件40与所述旋转件100中的另一者设有旋转槽46。
从上述内容可知，无论旋转件100与转动件10是否为同心设置，旋转件100均可转动连接于第一装配件40上。因此本实施方式提供了多种实现方式。一种实现方式中，可增设轴套110，使轴套110转动连接第一装配件40，并使旋转件100套设轴套110上，从而实现旋转件100可相对第一装配件40旋转。
可选地，可在旋转件100上开设旋转孔130，通过旋转孔130使旋转件100套设于轴套110上。并在第一装配件40上开设旋转空间44，在旋转空间44的侧壁92上开设第二转动空间45，轴套110的端部设于第二转动空间45内，从而完成装配。轴套110的两端可一端设于第二转动空间45内，另一端与转轴20共同设于第一转动空间41内。此时转动件10与旋转件100可同心设置，也可偏心设置。进一步可选地，当转动件10与旋转件100同心设置时，轴套110也可以为转轴20的一部分，即转轴20贯穿第一转动空间41的第一转动孔并设于第二转动空间45内，此时位于第一转动空间41与第二转动空间45之间的转轴20部分便可理解为轴套110。
另一种实现方式中，可通过旋转块120或旋转槽46的形式来实现旋转。例如可在第一装配件40上设置旋转块120，在旋转件100上设置旋转槽46。或者在第一装配件40上设置旋转槽46，在旋转件100上设置旋转块120。本实施方式对旋转块120于旋转槽46的位置并不进行限定，本实施方式仅以第一装配件40上设置旋转槽46，在旋转件100上设置旋转块120进行示意性说明。
上述内容便为本申请折叠机构1的详细介绍。本申请除了介绍折叠机构1之外，还介绍了一种应用该折叠机构1的电子设备2。请参考图30，图30为本申请一实施方式中电子设备的侧视图。本实施方式提供了一种电子设备2，包括柔性屏3，两个壳体4，及如本申请上述实施方式提供的折叠机构1，至少部分所述折叠机构1设于两个所述壳体4之间，且一个所述壳体4连接一个所述转动件10，另一个所述壳体4连接另一个所述转动件10，所述柔性屏3装设于两个所述壳体4上。
关于电子设备2的种类上述内容已详细提及，本实施方式在此不再赘述。本实施方式仅以电子设备2为柔性折叠手机进行示意性说明。本实施方式通过采用上述实施方式提供的折叠机构1，使一个所述壳体4连接一个所述转动件10，另一个所述壳体4连接另一个所述转动件10，当两个转动件10同步转动时可带动两个壳体4同步转动。本实施方式在侧视图中将转动件10以虚线进行示出。这样可提高电子设备2同步的可靠性与同步效果，提高传动效率，降低转动空行程。另外，由于只需要滑动件30便可实现同步传动，因此可减小弯折半径，减小两半柔性屏3之间的距离，提高外观性能。此时柔性折叠手机也可称之为书页式柔性屏3折叠手机。
另外，本实施方式对比文件电子设备2中折叠机构1的数量并不进行限定，例如电子设备2中折叠机构1的数量可以为一个，也可以为多个。
请一并参考图31-图33，图31为本申请以实施方式中电子设备的部分结构示意图。图32为图31的部分爆炸图。图33为本申请一实施方式中支架、转轴、以及转动件的分解示意图。本实施方式中，所述折叠机构1还包括支架90，设于所述导轨50背离所述滑动件30的一侧，也可以理解为设于所述折叠机构1背离所述柔性屏的一侧。所述第一装配件40与所述第二装配件70装设于所述支架90；所述转轴20转动连接所述支架90，或者所述转轴20转动连接所述第二装配件70。
支架90主要起支撑、固定的作用，可将支架90设于导轨50背离滑动件30的一侧，即滑动件30设于导轨50与支架90之间，可利用支架90来限制滑动件30朝向支架90方向的运动。并且本实施方式可使第一装配件40与第二装配件70装设于支架90上，从而实现对第一装配件40与第二装配件70的固定，实现对装配于第一装配件40与第二装配件70上的各结构件的结构限位。
可选地，如图32所示，可在支架90对应的位置也开设螺钉孔52，将螺钉51装设于导轨50、第一装配件40、以及支架90的螺钉孔52内以实现导轨50、第一装配件40、以及支架90的装配。同时螺钉51也可设于导轨50、第二装配件70、以及支架90的螺钉孔52内以实现导轨50、第二装配件70、以及支架90的装配，最终实现上述结构件与支架90的稳固连接。
从上述内容可知，转轴20的一端转动连接第一装配件40，至于转轴20的另一端可转动连接支架90，也可转动连接与第二装配件70。本实施方式对此并不进行限定。本实施方式仅以转轴20的另一端转动连接支架90进行示意性说明。可选地，如图33所示，支架90上述设有转动座93，转动座93上设有第二转动孔930，转轴20的另一单贯穿第二转动孔930来实现转轴20的转动，实现对转动件10非转动方向上的限位。进一步可选地，转动座93设于支架90的本体91上。进一步可选地，转轴20包括第一部23与第二部24，部分第二部24设有扁位结构240，其余的第二部24贯穿第二转动孔930来实现转轴20转动连接支架90，其余的第二部24可以理解为转动部241。具体地，第二转动孔930的形状为圆形，转动部241在周向方向上的形状也圆形。
可选地，扁位结构240设于转动部241靠近滑动件30的一侧，由于转动部241与转动座93相配合，这样当转动件10套设于扁位结构240时可利用转动座93对转动件10进行限位，防止转动件10从转轴20上分离。进一步可选地，扁位结构240设于转动部241的相对两侧，这样不仅可利用转动座93对转动件10进行限位，也可利用转动件10对转轴20进行限位。并且转动件10的结构也可以适应性改变。本实施方式仅以扁位结构240设于转动部241的相对两侧进行示意性说明。
请一并参考图27、图34-图35，图34为本申请一实施方式中折叠机构内折时的部分立体结构示意图。图35为本申请一实施方式中折叠机构外折时的部分立体结构示意图。本实施方式中，所述支架90包括本体91、及与所述本体91周缘弯折连接的侧壁92，所述本体91与所述侧壁92围设形成装设空间94，所述第一装配件40与所述第二装配件70装设于所述本体91，所述侧壁92背离所述本体91的一侧、以及所述侧壁92背离所述装设空间94的一侧设有避让空间95，部分所述转动件10能够设于所述避让空间95内。
对于支架90来说，它的形状可能并不是平直的，而是包括本体91与侧壁92。其中本体91理解为支架90的底壁，主要用来装设各种各样的结构件，例如第一装配件40与第二装配件70等等。而侧壁92则是与本体91周缘弯折连接，凸出的结构。侧壁92与本体91可围设形成一装设空间94，利用该空间更好地装设与保护支架90上的结构件，侧壁92也可以用于与其他结构件例如壳体进行配合。并且，本体91与侧壁92可以为一体式结构，也可以为分体式结构。当本体91与侧壁92为一体式结构时，本体91与侧壁92可通过一道工序制备而成，为了便于理解，人为对本体91与侧壁92进行了不同的命名。当本体91与侧壁92为分体式结构时，本体91与侧壁92可分别形成，再通过各种方式装配到一起。本实施方式对本体91与侧壁92的配合关系并不进行限定。
从上述内容可知，折叠机构1具有展开状态与折叠状态，如图27所示，展开状态为两个转动件10 水平设置时夹角为180°时的状态，折叠状态为两个转动件10竖直设置时夹角为0°或360°时的状态，即上述内容提及的内折与外折。如图34所示，当从展开状态至折叠状态的过程中，若转动件10的连接端12沿远离本体91的方向转动时，此时可认为是折叠机构1的内折。如图35所示，若转动件10的连接端12先沿靠近本体91的方向转动、再沿远离本体91的方向转动时，此时可认为是折叠机构1的外折。当折叠机构1内折时，此时侧壁92不会影响转动件10的转动，但当折叠机构1外折时，侧壁92的存在便会影响转动件10的转动。因此本实施方式可在侧壁92上开设避让空间95，具体地，可在侧壁92背离本体91的一侧，以及侧壁92背离装设空间94的一侧开设避让空间95，即在侧壁92的上表面与侧壁92的外表面开设避让空间95。这样当转动件10转动时便可利用该避让空间95对转动件10进行避让，使部分所述转动件10能够设于所述避让空间95内，防止出现转动时卡死等问题。因此本实施方式提供的折叠机构1具有两种不同的折叠状态，既可以内折也可以外折，提高了折叠机构1转动的多样性。
可选地，避让空间95包括但不限于避让槽或避让孔。当避让空间95为避让槽时，避让槽还可设于侧壁92靠近装设空间94的一侧，即避让槽将侧壁92相对的两侧贯穿，进一步提高避让效果。进一步可选地，如图33所示，当避让空间95为避让槽时，转动件10靠近侧壁92的一侧也可适应设置退让槽，或者转动件10靠近侧壁92的一侧朝向远离侧壁92的方向凸出，以围设形成退让空间14。换句话说，可在侧壁92与转动件10上均进行设置，通过侧壁92与转动件10的配合进一步提高避让效果。本实施方式仅以避让空间95为避让槽，转动件10靠近侧壁92的一侧朝向远离侧壁92的方向凸出进行示意性说明。
当避让空间95为避让孔时，避让孔可贯穿侧壁92与本体91，形成从上之下贯穿的通孔，提高避让空间95的大小，从而进一步提高避让效果。至于避让空间95具体为避让槽还是避让孔，本实施方式并不进行限定，可根据转动件10的结构，尺寸等情况进行设置，只要能使折叠机构1实现外折即可。
上述从转动件10转动时转动方向的角度介绍了折叠机构1内折与外折的区别。本实施方式将从静态的角度再次讨论折叠机构1内折与外折的区别。本实施方式中，所述折叠机构1具有所述转动件10的延伸方向平行于两个所述转轴20的排列方向时的展开状态、以及所述转动件10的延伸方向垂直于两个所述转轴20的排列方向时的折叠状态，当所述折叠机构1处于所述展开状态时，所述转动件10具有相背设置的第一表面15与第二表面16，所述第一表面15相较于所述第二表面16远离所述本体91；当所述折叠机构1处于所述折叠状态时，两个所述第一表面15相互靠近，或者两个所述第二表面16相互靠近。
如图27所示，当折叠机构1处于展开状态时，即两个转动件10展平且夹角为180°，此时转动件10具有相背设置的第一表面15与第二表面16，第一表面15相较于第二表面16远离本体91，第一表面15为转动件10的上表面，第二表面16为转动件10的下表面。将转动件10的第一表面15与第二表面16定义完成后，当折叠机构1处于所述折叠状态时，折叠机构1具有两种折叠方式：内折与外折。如图34所示，当折叠机构1内折时，此时两个第一表面15相互靠近，两个第二表面16相互远离。如图35所示，当折叠机构1外折时，此时两个第二表现相互靠近，两个第一表面15相互远离。可选地，当折叠机构1处于展开状态时，两个所述第一表面15齐平设置。
请再次参考图32，本实施方式中，所述本体91上设有沿所述滑动件30移动的方向上间隔设置的两个限位部96，所述第一装配件40设于两个所述限位部96之间。
本实施方式可在本体91上设有间隔设置的两个限位部96，两个限位部96的排列方向平行于滑动件30移动的方向(如图32中D2所示)，两个限位部96的延伸方向平行与两个转轴20的排列方向(如图32中D4所示)。将第一装配件40设于两个限位部96之间可进一步限制第一装配件40在滑动件30移动方向上的位移，提高第一装配件40的稳固性能。并且，本体91与限位部96可以为一体式结构，也可以为分体式结构。当本体91与限位部96为一体式结构时，本体91与限位部96可通过一道工序制备而成，为了便于理解，人为对本体91与限位部96进行了不同的命名。当本体91与限位部96为分体式结构时，本体91与限位部96可分别形成，再通过各种方式装配到一起。本实施方式对本体91与限位 部96的配合关系并不进行限定。
可选地，两个限位部96在两个转轴20的排列方向上的尺寸可以相等也可以不等。
请再次参考图22与图32，本实施方式中，所述滑动件30靠近所述本体91的一侧设有第一滑动部39，所述本体91上设有第二滑动部97，所述第一滑动部39与所述第二滑动部97配合使所述滑动件30沿所述转轴20的轴向D方向滑动。
滑动件30靠近所述本体91的一侧可设置第一滑动部39，也可以理解为滑动件30背离导轨50的一侧设置第一滑动部39。本体91上可相应设置第二滑动部97，第一滑动部39与第二滑动部97的延伸方向可平行于滑动件30的移动方向，这样便可利用第一滑动部39与第二滑动部97相互配合来对滑动件30进行导向移动的作用，使滑动件30沿转轴20的轴向D方向移动。并且，本体91与第二滑动部97可以为一体式结构，也可以为分体式结构。当本体91与第二滑动部97为一体式结构时，本体91与第二滑动部97可通过一道工序制备而成，为了便于理解，人为对本体91与第二滑动部97进行了不同的命名。当本体91与第二滑动部97为分体式结构时，本体91与第二滑动部97可分别形成，再通过各种方式装配到一起。本实施方式对本体91与第二滑动部97的配合关系并不进行限定。
可选地，第一滑动部39包括滑槽或滑块。当第一滑动部39为滑槽时，第二滑动部97相应为滑块。当第一滑动部39为滑块时，第二滑动部97相应为滑槽。进一步可选地，当第一滑动部39为滑槽时，第二滑动部97为滑块。本实施方式可利用上述设置的第一凹槽36与第二凹槽38来充当滑槽，因此只需在本体91上凸设滑块即可实现对滑动件30的导向移动作用。另外，滑槽的槽壁还可对滑块起到在两个转轴20排列方向上的限位作用，防止滑动件30在移动时沿非移动方向进行移动。
以上对本申请实施方式所提供的内容进行了详细介绍，本文对本申请的原理及实施方式进行了阐述与说明，以上说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
