在转轴组件22的其他弯折方式中，可以将第二转动机构245的第二转动件246绕第二圆弧条2320 及第二圆弧轨2502相对于基座23向第一转动机构240转动，抵顶件250的第二抵顶部2508脱离与第三限位部2466的限位而滑动地抵顶于第二阻尼部2468，直至第二抵顶部2508抵顶第四限位部2467；同时，第二同步件285的第二传动部2851绕第二螺旋轨2806相对于基座23向第一同步件283转动，以使第二同步件285绕第四转动轴心线L4转动且无法沿第四转动轴心线L4方向移动；第二传动部2851在第二螺旋槽2805中转动，两个第二抵顶面2851a分别滑动地抵推两个第二螺旋面2805a，使得联动件280沿平行于中心线O方向滑动；联动件280的第一螺旋轨2803在对应的第一传动槽2831b中滑动，第一螺旋面2804a滑动地抵推第一抵顶面2831a，使得第一传动部2831在联动件280的第一螺旋槽2804中转动，以使第一同步件283相对于基座23，即第一同步件283仅能围绕第三转动轴心线L3转动而无法沿第三转动轴心线L3的方向滑动；因此，第一同步件283相对于基座23转动及第二同步件285相对于基座23转动而相互靠拢。同时，第二转动件246绕第二圆弧轨2502转动及第一转动件241绕第一圆弧轨2501转动，第二连接件248与第二侧部支撑件275通过第四圆弧轨2751与第四圆弧槽2482的配合相互转动，且第二侧部支撑件275与第二同步件285通过第四圆弧轨2751与第六圆弧槽2856a的配合相互转动，第一连接件243与第一侧部支撑件273通过第三圆弧轨2731与第三圆弧槽2432的配合相互转动，且第一侧部支撑件273与第一同步件283通过第三圆弧轨2731与第五圆弧槽2836a的配合相互转动，以使得第二侧部支撑件275的第二调节臂2753与第二调节轴2372之间转动并滑动地连接，第一侧部支撑件273的第一调节臂2733与第一调节轴2362之间转动并滑动地连接。即第二调节轴2372在第二调节槽2754中从第三定位段2754a转动并滑动至第四定位段2754b，第一调节轴2362在第一调节槽2734中从第一定位段2734a转动并滑动至第二定位段2734b，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2362限位于第二定位段2734b及第二调节轴2372限位于第四定位段2754b，抵顶件250的第一抵顶部2507及第二抵顶部2508分别限位于第二限位部2417及第四限位部2467，以防止第一转动机构240及第二转动机构245分别相对于基座23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机构240的第一转动件241绕第一圆弧条2310及第一圆弧轨2501相对于基座23向第二转动机构245转动及将第二转动机构245的第二转动件246绕第二圆弧条2320及第二圆弧轨2502相对于基座23向第一转动机构240转动，第一同步件283的第一传动部2831及第二同步件285的第二传动部2851分别在第一螺旋槽2804及第二螺旋槽2805转动而相互靠拢；第一调节轴2362在第一调节槽2734中转动并滑动，第二调节轴2372在第二调节槽2754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2362限位于第二定位段2734b及第二调节轴2372限位于第四定位段2754b；同时，第一同步件283的第一抵顶面2831a及第二同步件285的第二抵顶面2851a同步分别抵推第一螺旋面2804a及第二螺旋面2805a，以使联动件280沿中心线O的方向(即X轴方向)相对于基座23滑动，直至第一抵顶部2507定位于第二限位部2417及第二抵顶部2508定位于第四限位部2467，以防止第一转动机构240、第二转动机构245、第一同步件283及第二同步件285分别相对于基座23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上的第三圆弧轨2731分别在第一连接件243的第三圆弧槽2432及第一同步件283的第五圆弧槽2836a转 动，同时第二侧部支撑件275的第四圆弧轨2751分别在第二连接件248的第四圆弧槽2482及第二同步件285的第六圆弧槽2856a中转动，同时，第一调节轴2362及第二调节轴2372同时分别在第一调节槽2734及第二调节槽2754中转动并滑动。具体地，第一调节轴2362从第一定位段2734a位移至第二定位段2734b，第二调节轴2372从第三定位段2754a位移至第四定位段2754b；同时，第一传动部2831及第二传动部2851分别在第一螺旋槽2804及第二螺旋槽2805中同步转动，第一抵顶面2831a及第二抵顶面2851a分别滑动地抵推第一螺旋面2804a及第二螺旋面2805a，使得联动件280沿中心线O的方向移动，第一抵顶部2507脱离与第一限位部2416的限位而相对于第一阻尼部2418滑动，直至第一抵顶部2507抵顶第二限位部2417，以及第二抵顶部2508脱离与第三限位部2466的限位而相对于第二阻尼部2468滑动，直至第二抵顶部2508抵顶第四限位部2467。通过第一同步件283围绕第一螺旋轨2803转动以带动联动件280相对于基座23滑动，联动件280同步带动第二同步件285围绕第二螺旋轨2806转动，实现第一同步件283和第二同步件285的同步折叠；或者通过第二同步件285围绕第二螺旋轨2806转动以带动联动件280相对于基座23滑动，联动件280同步带动第一同步件283围绕第一螺旋轨2803转动，实现第一同步件283和第二同步件285的同步折叠。因此，转轴组件22的同步机构28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，在第一抵顶部2507相对于第一阻尼部2418滑动及第二抵顶部2508相对于第二限尼部2556c滑动时，抵顶件250与第一转动件241及第二转动件246之间的摩擦阻力，能使第一转动机构240及第二转动机构245相对于基座23定位、第一同步件283及第二同步件285相对于基座23定位，以及联动件280相对于基座23定位，使得第一转动机构240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机构245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。

请一并参阅图1-图5及图20-图27，弯折电子设备100时，对电子设备100的两个框体21中的至 少其中一个施加折弯的力，使连接于两个框体21的第一转动机构240及第二转动机构245相对于基座23转动而朝相互靠拢的方向转动，同时，第一同步件283及第二同步件285相对于基座23转动而相互靠拢的方向转动，第一侧部支撑件273远离基座23的一侧相对于第一连接件243及第一同步件283转动，且第一侧部支撑件273与基座23之间通过第一调节轴2362与第一调节槽2734的配合转动并滑动地连接，第二侧部支撑件273远离基座23的一侧相对于第二连接件248及第二同步件285转动，且第二侧部支撑件273与基座23之间通过第二调节轴2372与第二调节槽2754的配合转动并滑动地连接，以实现转轴组件22的同步折叠，柔性屏30的可折弯区31随转轴组件22弯折。具体地，若对连接于第一连接件243和第一同步件240的框体21施加折弯的力，该框体21带动第一转动件241围绕第一圆弧条2310及第一圆弧轨2501相对于基座23向靠近柔性屏30的一侧转动，第一转动部2831抵推联动件280滑动而带动第二螺旋槽2805中的第二传动部2851围绕第二连接部2802相对于基座23同步转动，从而实现第一同步件283和第二同步件285相对于基座23同步转动而相互靠拢。同时，第一连接件243与第一侧部支撑件273之间通过第三圆弧轨2731与第三圆弧槽2432的配合转动，第一同步件283与第一侧部支撑件273之间通过第五圆弧槽2836a与第三圆弧轨2731的配合转动，第二连接件248与第二侧部支撑件275之间通过第四圆弧轨2751与第四圆弧槽2482的配合转动，第二同步件285与第二侧部支撑件275之间通过第六圆弧槽2856a与第四圆弧轨2751的配合转动，基座23上的第一调节轴2362及第二调节轴2372分别在第一调节槽2734及第二调节槽2754中滑动并转动，以使基座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2362限位于第二定位段2734b及第二调节轴2372限位于第四定位段2754b，且抵顶件250的第一抵顶部2507限位于第二限位部2417，同时，第二抵顶部2508限位于第四限位部2467，以防止第一转动机构240、第二转动机构245、第一同步件283及第二同步件285相对于基座转动，防止联动件280相对于基座23滑动，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；柔性屏30的可折弯区31随转轴组件22弯折，直至可折弯区31弯折成水滴状，从而实现电子设备100的折叠。
在展平电子设备100时，对电子设备100的两个框体21中的至少其中一个施加展平的力，使连接于两个框体21的第一转动机构240及第二转动机构245相对于基座23转动而朝相互远离的方向转动，同时，第一同步件283及第二同步件285相对于基座23转动而朝相互远离的方向转动；第一侧部支撑件273远离基座23的一侧相对于第一连接件243及第一同步件283转动，且第一侧部支撑件273与基座23之间通过第一调节轴2362与第一调节槽2734的配合转动并滑动地连接，第二侧部支撑件273远离基座23的一侧相对于第二转动件246及第二同步件285转动，且第二侧部支撑件273与基座23之间通过第二调节轴2372与第二调节槽2754的配合转动并滑动地连接，以实现转轴组件22的展平，柔性屏30的可折弯区31随转轴组件22展平。具体地，若对连接于第一连接件243和第一同步件240的框体21施加展平的力，该框体21带动第一转动件241围绕第一圆弧条2310及第一圆弧轨2501相对于基座23向远离柔性屏30的一侧转动；第一传动部2831抵推联动件280滑动以带动第二螺旋槽2805中的第二传动部2851围绕第二连接部2802相对于基座23同步转动，使得第二转动件246向远离柔性屏30的一侧同步转动，从而实现第一转动机构240和第二转动机构245相对于基座23同步转动而相互远离；同时，第一连接件243与第一侧部支撑件273之间通过第三圆弧轨2731与第三圆弧槽2432的配合转动，第一同步件283与第一侧部支撑件273之间通过第五圆弧槽2836a与第三圆弧轨2731的配合转动，第 二连接件248与第二侧部支撑件275之间通过第四圆弧轨2751与第四圆弧槽2482的配合转动，第二同步件285与第二侧部支撑件275之间通过第六圆弧槽2856a与第四圆弧轨2751的配合转动，基座23上的第一调节轴2362及第二调节轴2372分别在第一调节槽2734及第二调节槽2754中滑动并转动，使基座23相对两侧的第一侧部支撑件273和第二侧部支撑件275相互远离，直至第一抵顶部2507限位于第一限位部2416及第二抵顶部2508限位于第三限位部2466，以使基座23相对两侧的第一侧部支撑件273与第二侧部支撑件275相互展平，直至第一侧部支撑件273与第二侧部支撑件275呈展平状，柔性屏30的可折弯区31随转轴组件22展平，直至柔性屏30完全展平，从而实现电子设备100的展平。
本发明的电子设备100的转轴组件22通过第一同步件283及第二同步件285相对于基座23同步转动而实现同步折弯或同步展开，操作方便；转轴组件22的元件较少，结构简单，制造成本低，减少了转轴组件22占用壳体20的内部空间，有利于主板或电池等其他元件的布局。其次，在电子设备100处于完全折叠状态时，第一调节轴2362限位于第二定位段2734b及第二调节轴2372限位于第四定位段2754b，且第一抵顶部2507限位于第二限位部2417及第二抵顶部2508限位于第四限位部2467，因此，电子设备100跌落时各元件不易移位，避免损坏柔性屏30；在电子设备100处于完全展平状态时，第一调节轴2362限位于第一定位段2734a及第二调节轴2372限位于第三定位段2754a，且第一抵顶部2507限位于第一限位部2416及第二抵顶部2508限位于第三限位部2466，因此，电子设备100跌落时各元件不易移位，避免损坏柔性屏30。另外，转轴组件22通过第一抵顶部2507与第一阻尼部2418之间的摩擦阻力和第二抵顶部2508与第二阻尼部2468之间的摩擦阻力使得柔性屏30的可折弯区31定位于任意一弯曲角度，从而使两个框体21能在展平状态、折叠状态及中间状态自由调整，即电子设备100可以定位在展平状态、折叠状态及任意一中间状态，使得电子设备100的两个框体21之间具有0度至180度的悬停功能，悬停角度范围大。
