请一并参阅图1至图3，本发明第一实施例中的电子设备100包括折叠壳体20及设置于折叠壳体20上的柔性屏30。柔性屏30可以是但不限于柔性显示屏、柔性触摸屏、柔性触摸显示屏等各种具备相应功能的柔性部件，或者为固定贴合有柔性支撑板的柔性部件，如贴合有柔性钢板的柔性显示屏、柔性触摸屏等。柔性屏30能随折叠壳体20折弯或展平。折叠壳体20包括两个框体21及连接于两个框体21之间的转轴组件22，转轴组件22相对的两侧分别连接于两个框体21，两个框体21通过转轴组件22实现折叠或展平。柔性屏30包括对应转轴组件22的可折弯区31，以及连接于可折弯区31相对的两侧的两个非折弯区33。柔性屏30连接于两个框体21及转轴组件22。本实施例中，柔性屏30设置于两个框体21的正面及转轴组件22的正面，具体地，柔性屏30的两个非折弯区33可分别固定在两个框体21的正面，可折弯区31贴合于转轴组件22的正面。柔性屏30的可折弯区31能随转轴组件22折弯或展平。
请一并参阅图4-图9，转轴组件22包括基座23、阻尼机构24、转动机构25及支撑机构27，转动机构25连接于基座23与支撑机构27之间；转动机构25包括联动件250、第一转动件253及第二转动件255，联动件250滑动地连接于基座23并能沿第一方向相对于基座23滑动，即该第一方向平行于联 动件250相对于基座23的滑动方向，联动件250包括第一连接部2501和第二连接部2502；第一转动件253设于基座23的一侧，第二转动件255设于基座23相对的另一侧，也就是第一转动件253和第二转动件255分别设置于基座23相对的两侧；第一转动件253与第一连接部2501之间通过第一螺旋槽与第一传动部的配合转动地连接，第二转动件255与第二连接部2502之间通过第二螺旋槽与第二传动部的配合转动地连接，该第一螺旋槽与该第二螺旋槽的旋向相反；阻尼机构24与第一转动件253抵顶，和/或阻尼机构24与第二转动件255抵顶，当第一转动件253及第二转动件255相对于阻尼机构24转动时，第一转动件253与阻尼机构24之间的摩擦阻力和/或第二转动件255与阻尼机构24之间的摩擦阻力，以限定第一转动件253及第二转动件255相对于基座23转动；使得第一转动件253相对于基座23定位在0度至90度之间的任意角度，第二转动件255相对于基座23定位在0度至90度之间的任意角度。
本实施例中，阻尼机构24与第一转动件253和第二转动件255抵顶，第一转动件253与阻尼机构24之间的摩擦阻力和第二转动件255与阻尼机构24之间的摩擦阻力共同限定第一转动件253及第二转动件255相对于基座23转动。
在一些实施例中，阻尼机构24与第一转动件253抵顶，第一转动件253与阻尼机构24之间的摩擦阻力限定第一转动件253及第二转动件255相对于基座23转动。在一些实施例中，阻尼机构24与第二转动件255抵顶，第二转动件255与阻尼机构24之间的摩擦阻力限定第一转动件253及第二转动件255相对于基座23转动。
支撑机构27包括第一侧部支撑件273及第二侧部支撑件275，第一侧部支撑件273的一侧滑动且转动地连接于基座23，第一侧部支撑件273相对的另一侧转动地连接于第一转动件253；第二侧部支撑件275的一侧滑动且转动地连接于基座23，第二侧部支撑件275相对的另一侧转动地连接于第二转动件255；在联动件250沿第一方向相对于基座23滑动时，第一转动件253和第二转动件255相对于基座23同步转动以使第一转动件253和第二转动件255同步远离或同步靠拢，使得第一侧部支撑件273和第二侧部支撑件275能实现相互展开或相互折叠。具体地，当第一转动件253相对于第一连接部2501转动时，第一传动部沿第一螺旋槽移动使得联动件250相对于基座23滑动，同时，基座23的滑动使第二传动部沿第二螺旋槽移动，进而使得第二转动件255相对于第二连接部2502同步转动；当第二转动件255相对于第二连接部2502转动时，第二传动部沿第二螺旋槽移动使得联动件250相对于基座23滑动，同时，基座23的滑动使第一传动部沿第一螺旋槽移动，使得第一转动件253相对于第一连接部2501同步转动；从而实现第一转动件253和第二转动件255的同步折叠或同步展开，以带动第一侧部支撑件273和第二侧部支撑件275同步折叠或同步展开，同时，带动两个框体21同步折叠或同步展开，使得柔性屏30的可折弯区31弯曲或展平。
本实施例中，正面指与柔性屏30的出光面朝向相同的面，背面指与柔性屏30的出光面朝向背离的面。电子设备100例如是，但不局限于手机、平板电脑、显示器、液晶面板、OLED面板、电视、智慧手表、VR头戴显示器、车载显示器等其它任何具有显示功能的产品和部件。
本发明转轴组件22的联动件250滑动地设于基座23上，第一转动件253通过第一传动部与第一螺旋槽的配合转动地连接于第一连接部2501，第二转动件255通过第二传动部与第二螺旋槽的配合转动地连接于第二连接部2502；只需该第一传动部相对于第一螺旋槽转动或该第二传动部相对于第二螺旋槽转动，就能实现第一转动件253和第二转动件255相对于基座23的同步折叠或同步展开，从而实现第一 侧部支撑件273和第二侧部支撑件275同步折叠或同步展开。相较于现有技术中需通过齿轮与齿轮的啮合才能实现联动，本申请转轴组件22省略了齿轮、齿轮安装架等元件，不仅减少了元件，简化了结构，降低了制造成本，且减小了转轴组件22的体积，从而减小转轴组件22占用折叠壳体20的内部空间，有利于电子设备100中主板或电池等其他元件的布局，有利于小型化发展；另外，阻尼机构24与第一转动件253和/或第二转动件255抵顶，在第一侧部支撑件273和第二侧部支撑件275同步折叠或同步展开的过程中，阻尼机构24与第一转动件253之间的摩擦阻力，和/或阻尼机构24与第二转动件255之间的摩擦阻力，以使得第一侧部支撑件273和第二侧部支撑件275分别相对于基座23定位，使得电子设备100能实现悬停；其次，转轴组件22的转动机构25及基座23体积均较小，从而减少占用转轴组件22的空间，使得转轴组件22具有大量的空间用于收容其他元件，如设于支撑机构27下方的导热件或柔性电路板等，该导热件相对的两端分别连接于两个框体21，电子设备100的主板、电池等元件工作时产生的热量经该导热件传导至两个框体21上，有利于电子设备100的散热，该柔性电路板相对的两端电性连接于两个框体21内的电路板。
如图2及图3所示，框体21包括正面211、背面、相对的两侧面214及两端面215，转轴组件22连接于两个框体21相邻的两个端面215之间，柔性屏30的可折弯区31贴附于转轴组件22的正面，柔性屏30的非折弯区33连接于框体21的正面211。每一框体21的正面211靠近转轴组件22的一端设有安装槽216，安装槽216穿通框体21的正面211，安装槽216相对的两端分别延伸至靠近框体21相对的两侧面214。转轴组件22相对的两侧分别容置于两个框体21的安装槽216中，且第一转动件253及第二转动件255远离基座23的一侧分别与对应的框体21固定连接。框体21的背面设有若干收容空间(图中未示)，收容空间用于安装电路板、电池等电子器件。

当第一侧部支撑件273和第二侧部支撑件275呈完全展平状态时，第一调节轴2366及第二调节轴2367分别定位于第一侧部支撑件273的第一定位段2733a及第二侧部支撑件275的第三定位段2753a；第一抵顶件240在第一弹性件260的抵推下使第一抵顶面2421抵顶于第一转动件253的第一限位部2536a，第二抵顶件245在第二弹性件265的抵推下使第二抵顶面2471抵顶于第二转动件255的第三限位部2556a，使得第一转动件253和第二转动件255相对于基座23限位，以限制联动件250相对于基座23滑动，使第一侧部支撑件273和第二侧部支撑件275保持稳定的完全展平状态，第一侧部支撑件273的正面与第二侧部支撑件275的正面共面。优选地，第一侧部支撑件273与第二侧部支撑件275相互面朝的侧面接触，即第一侧部支撑件273与第二侧部支撑件275之间的间隔较小。当第一侧部支撑件273与第二侧部支接掌件275呈完全折叠状态时，第一调节轴2366及第二调节轴2367分别定位于第一侧部支撑件273的第二定位段2733b及第二侧部支撑件275的第四定位段2753b；第一抵顶件240在第一弹性件260的抵推下使第一抵顶面2421抵顶于第一转动件253的第二限位部2536b，第二抵顶件245在第二弹性件265的抵推下使第二抵顶面2471抵顶于第二转动件255的第四限位部2556b，使得第一转动件253和第二转动件255相对于基座23限位，以限制联动件250相对于基座23滑动，使第一侧部支撑件273和第二侧部支撑件275保持稳定的完全折叠状态，第一侧部支撑件273的正面、第二侧部支撑件275的正面与联动件250的正面围成水滴形空间，方便收容柔性屏30的可折弯区31。当第一抵顶件240在 第一弹性件260的抵推下使第一抵顶面2421抵顶于第一阻尼部2536c及第二抵顶件245在第二弹性件265的抵推下使第二抵顶面2471抵顶第二阻尼部2556c时，第一侧部支撑件273和第二侧部支撑件275呈中间状态时，第一抵顶件240和第二抵顶件245分别抵顶第一阻尼部2536c和第二阻尼部2556c；以使第一侧部支撑件273与第二侧部支撑件275能保持在除完全展平状态和完全折叠状态外的任意一折叠状态，使得电子设备100呈任意一悬停状态。
需要说明的是：完全展平状态是指第一连接部2533的正面与第二连接部2553的正面共平面，即第一侧部支撑件273的正面与第二侧部支撑件275的正面之间的夹角为180度；完全折叠状态是指第一连接部2533的正面与第二连接部2553的正面相互平行，即第一连接部2533的正面与第二连接部2553的正面之间的夹角为0度，第一侧部支撑件273的正面和第二侧部支撑件275的正面围成水滴形空间；中间状态是指第一连接部2533的正面与第二连接部2553的正面之间的夹角大于0度小于180度，第一侧部支撑件273的正面和第二侧部支撑件275的正面围成除共面和水滴形空间外的任意折叠状态，也就是两个框体21正面之间的夹角在大于0度小于180度范围内的电子设备100的折叠状态。
如图16-图25及图27-图36所示，将转轴组件22由展平状态进行弯折时，将第一转动件253绕第一圆弧板2503相对于基座23向第二转动件255转动，第一转动件253的第一转动板2536围绕第一圆弧板2503转动,以使第一转动件253绕第一转动轴心线L1转动且无法沿第一转动轴心线L1方向移动；第一传动部2531在第一螺旋槽2504中滑动，两个第一抵推面2532分别滑动地抵推两个第一螺旋面2507，使得联动件250沿中心线O向远离连接块236的一端滑动。联动件250的导滑轨2515在对应的导滑槽234中滑动，基座23的导滑部2306在对应的滑槽2516中滑动，第一抵顶件240的第一抵顶面2421脱离与第一限位部2536a的限位而相对于第一转动板2536的第一阻尼部2536c滑动，直至第一抵顶面2421抵顶第二限位部2536b。同时，联动件250的滑动能带动第二螺旋槽2505中的第二传动部2551相对于基座23转动，两个第二螺旋面2508分别滑动地抵顶两个第二抵推面2552，以使第二传动件255的第二转动板2556沿基座23的第二限位槽238转动，第二转动板2556仅能围绕第二转动轴心线L2转动而无法沿第二转动轴心线L2的方向滑动，使得第二转动件255随第二传动部2551相对于基座23转动；因此，第一转动件255随第一传动部2531相对于基座23转动及第二转动件255随第二传动部2551相对于基座23转动而相互靠拢。同时，第一转动件253相对于第一圆弧板2503转动及第二转动件255相对于第二圆弧板2506转动的过程中，第一转动件253与第一侧部支撑件273通过第一圆弧轨2731与第一圆弧槽2535的配合相互转动，第二转动件255与第二侧部支撑件275通过第二圆弧轨2751与第二圆弧槽2555的配合相互转动，使得第一侧部支撑件273的第一调节臂2734与第一调节轴2366之间转动并滑动地连接，第二侧部支撑件275的第二调节臂2754与第二调节轴2367之间转动并滑动地连接。即第一调节轴2366在第一调节槽2733中从第一定位段2733a转动并滑动至第二定位段2733b，第二调节轴2367在第二调节槽2753中从第三定位段2753a转动并滑动至第四定位段2753b，使基座23相对两侧的第一侧部支撑件273及第二侧部支撑件275相互靠拢，直至第一调节轴2366限位于第二定位段2733b及第二调节轴2367限位于第四定位段2753b，第一抵顶件240的第一抵顶面2421限位于第二限位部2536b，第二抵顶件245的第二抵顶面2471限位于第四限位部2556b，以防止第一抵顶件240及第二抵顶件245转动，第一侧部支撑件273的正面与第二侧部支撑件275的正面围成横截面成水滴状。
在转轴组件22的其他弯折方式中，可以将第二动件255绕第二圆弧板2506相对于基座23向第一 转动件253转动，第二转动件255的第二转动板2556围绕第二圆弧板2506转动，以使第二转动件255绕第二转动轴心线L2转动且无法沿第二转动轴心线L2方向移动；第二传动部2551在第二螺旋槽2505中滑动，两个第二抵推面2552分别滑动地抵推两个第二螺旋面2508，使得联动件250沿中心线O向远离连接块236的一端滑动。联动件250的导滑轨2515在对应的导滑槽234中滑动，基座23的导滑部2306在对应的滑槽2516中滑动，第二抵顶件245的第二抵顶面2471脱离与第三限位部2556a的限位而相对于第二转动板2556的第二阻尼部2556c滑动，直至第二抵顶面2471抵顶第四限位部2556b。同时，联动件250的滑动能带动第二螺旋槽2504中的第一传动部2531相对于基座23转动，两个第一螺旋面2507分别滑动地抵顶两个第一抵推面2532，以使第二传动件253的第一转动板2536沿基座23的第一限位槽237转动，第一转动板2536仅能围绕第一转动轴心线L1转动而无法沿第一转动轴心线L1的方向滑动，使得第一转动件253随第一传动部2531相对于基座23转动；因此，第一转动件255随第一传动部2531相对于基座23转动及第二转动件255随第二传动部2551相对于基座23转动而相互靠拢。同时，第二转动件255相对于第二圆弧板2506转动及第一转动件253相对于第一圆弧板2503转动的过程中，第一转动件253与第一侧部支撑件273通过第一圆弧轨2731与第一圆弧槽2535的配合相互转动，第二转动件255与第二侧部支撑件275通过第二圆弧轨2751与第二圆弧槽2555的配合相互转动，使得第一侧部支撑件273的第一调节臂2734与第一调节轴2366之间转动并滑动地连接，第二侧部支撑件275的第二调节臂2754与第二调节轴2367之间转动并滑动地连接。即第一调节轴2366在第一调节槽2733中从第一定位段2733a转动并滑动至第二定位段2733b，第二调节轴2367在第二调节槽2753中从第三定位段2753a转动并滑动至第四定位段2753b，使基座23相对两侧的第一侧部支撑件273及第二侧部支撑件275相互靠拢，直至第一调节轴2366限位于第二定位段2733b及第二调节轴2367限位于第四定位段2753b，第一抵顶件240的第一抵顶面2421限位于第二限位部2536b，第二抵顶件245的第二抵顶面2471限位于第四限位部2556b，以防止第一抵顶件240及第二抵顶件245转动，第一侧部支撑件273的正面与第二侧部支撑件275的正面围成横截面成水滴状。
在其他的弯折方式中，可以同时将第一转动件253及第二转动件255分别绕第一圆弧板2503及第二圆弧板2506相对于基座23朝相向方向一同转动，第一调节轴2366在第一调节槽2733中转动并滑动，第二调节轴2367在第二调节槽2753中转动并滑动，使得第一支撑件273及第二支撑件275相互靠拢，直至第一调节轴2366限位于第二定位段2733b及第二调节轴2367限位于第四定位段2753b；同时，第一传动部2531的第一抵推面2532及第二传动部2551的第二抵推面2552同步分别抵推第一螺旋面2507及第二螺旋面2508，以使联动件250沿中心线O的方向相对于基座23滑动，直至第一抵顶面2421定位于第二限位部2536b及第二抵顶面2471定位于第四限位部2556b，以防止第一抵顶件240及第二抵顶件245转动，第一侧部支撑件273的正面与第二侧部支撑件275的正面围成横截面成水滴状。
在第一侧部支撑件273及第二侧部支撑件275相对于基座23折弯过程中，第一侧部支撑件273上的第一圆弧轨2731及第二侧部支撑件275的第二圆弧轨2751同时分别在第一转动件253的第一圆弧槽2535及第二转动件255的第二圆弧槽2555中转动，同时，第一调节轴2366及第二调节轴2367同时分别在第一调节槽2733及第二调节槽2753中转动并滑动。具体地，第一调节轴2366从第一定位段2733a位移至第二定位段2733b，第二调节轴2367从第三定位段2753a位移至第四定位段2753b；同时，第一传动部2531及第二传动部2551分别在第一螺旋槽2504及第二螺旋槽2505中同步转动，第一抵推面2532 及第二抵推面2552分别滑动地抵推第一螺旋面2507及第二螺旋面2508，使得联动件250沿中心线O的方向逐渐远离连接块236移动，第一抵顶面2421脱离与第一限位部2536a的限位而相对于第一阻尼部2536c滑动，直至第一抵顶面2421抵顶第二限位部2536b，以及第二抵顶面2471脱离与第三限位部2556a的限位而相对于第二阻尼部2556c滑动，直至第二抵顶面2471抵顶第四限位部2556b。通过第一转动件253围绕第一连接部2501转动以带动联动件250相对于基座23滑动，联动件250同步带动第二转动件255围绕第二连接部2502转动，实现第一转动件253和第二转动件255的同步折叠；或者通过第二转动件255围绕第二连接部2502转动以带动联动件250相对于基座23滑动，联动件250同步带动第一转动件253围绕第一连接部2501转动，实现第一转动件253和第二转动件255的同步折叠。因此，转轴组件22的联动机构无需采用齿轮与齿轮的啮合实现，使得转轴组件22的结构简易，制造成本低，且转轴组件22的整体体积减小，有利于产品小型化发展；其次，在第一抵顶面2421相对于第一阻尼部2536c滑动及第二抵顶面2471相对于第二限尼部2556c滑动时，第一抵顶件240与第一转动板2536之间的摩擦阻力和第二抵顶件245与第二转动板2556之间的摩擦阻力，能使第一转动件253及第二转动件255相对于基座23定位以及联动件250相对于基座23定位，使得第一转动件253相对于基座23定位在0度至90度之间的任意角度及第二转动件255相对于基座23定位在0度至90度之间的任意角度；同时，使得第一侧部支撑件273和第二侧部支撑件275分别相对于基座23定位在0度至120度之间的任意角度，使得电子设备100能实现较大角度的悬停。
将转轴组件22由完全折叠状态进行展平时，各构件的运动过程与将转轴组件22由展平状态进行弯折时相逆，文中不再赘述。
