在一些实施例中，侧部支撑件233上的导滑槽2337可以省略，对应的联动件264上的第二导滑部2641也可以省略。
请一并参阅图1-图5，将安装完成的转轴装置22置于两个框体21之间，将背盖28相对两侧的连接件256分别容置于两个框体21的收容槽216中，并将两个连接件256分别固定连接于两个框体21。此时，两个框体21的正面211、两个侧部支撑件233的正面及中部支撑件231的正面共面。柔性件30的背面连接于两个框体21的正面211及转轴装置22的正面，具体地，可折弯区域31正对转轴装置22的正面，两个非折弯区域33分别正对两个框体21的正面。当柔性件30处在展平状态时，中部支撑件231与两个侧部支撑件233齐平，转轴装置22保持展平状态；另外，联动件264的第一导滑部2640滑动地容置于对应的侧部支撑件233的限位滑槽2330中，转轴装置22在弯折状态时，第一导滑部2640止挡于限位滑槽2330的第一限位段2330a，防止转轴装置22进一步弯折可能损坏柔性件30；转轴装置22在展平状态时，第一导滑部2640止挡于限位滑槽2330的第一限位段2330b，防止转轴装置22进一步展开可能损坏柔性件30。
请一并参阅图19-图28，弯折电子设备100时，对电子设备100的两个框体21至少其中一个施加折弯的力，使连接于两个框体21的转动组件253朝相互邻近的方向转动，通过联动组件26实现转轴装置22的折弯，柔性件30的可折弯区域31随支撑机构23弯折。具体地，如对其中一框体21施加折弯的力，所述其中一框体21带动对应的转动件254相对于定位座251向靠近柔性件30的一侧转动，转动件254的第二圆弧轨2541与定位座251的第二圆弧槽2511相对转动，连接件256带动联动件264和对应的转动轴266一并相对于联动座261转动第一导滑部2640限位滑槽2330，且联动件264的导滑条2647在导滑槽2568中滑动、联动件264的第一导滑部2640自限位滑槽2330的第二限位段2330b滑动至第一限位段2330a，以及联动件264的第二导滑部2641在导滑槽2337中自第二止挡部2337b滑动至第一止挡部2337a，以带动对应的联动件264和转动轴266一并转动，联动件264的转动带动对应的第一齿轮2651转动，通过齿轮组合265带动对应的两个第一齿轮2651同步转动，同步转动的第一齿轮2651带动对应的两个联动件264同步相互靠拢。同时，连接件256带动第一圆弧轨2562转动地连接于对应的第一圆弧槽2335中及转动件254带动第二圆弧轨2541转动地连接于对应的第二圆弧槽2551中；同时，两个转动组件253相对于定位座251同步转动而相互靠拢，以带动两个侧部支撑件233同步相互靠拢，使得转轴装置22呈折弯状态；柔性件30的可折弯区域31随转轴装置22弯折，直至柔性件30的两个非折弯区域33的正面相互贴合，可折弯区域31弯折成水滴状，从而实现电子设备100的无缝折叠。
在上述过程中，每一转动轴266上的第一凸轮2710与第二凸轮2730之间的摩擦扭力和摩擦件276与垫片277及定位件275之间的摩擦扭力大于柔性件30的反弹力，以使两个侧部支撑件233之间相对定位在特定角度，能使两个框体21限位在70度至130度之间的特定角度。柔性件30的可折弯区域31弯折围成水滴形，减少弯折后的可折弯区域31的占空比，从而能减小电子设备100的整体厚度。
如图20所示，侧部支撑件233与框体21之间的夹角C大于180°，由于连接件256与框体21固定，因此，电子设备100在折叠状态下，连接件256与框体21之间的角度为180度。柔性件30的非折弯区域33与框体21的正面、侧部支撑件233的正面与柔性件30的可折弯区域33通过背胶粘贴在一起，中部支撑件231与柔性件30不粘贴；柔性件30在折叠状态下，柔性件30的可折弯区域31分为第一可折弯区域312及第二可折弯区域314，也就是柔性件30分为对应框体21的非折弯区域33、对应侧部支撑件233的第一可折弯区域312,以及对应中部支撑件231的第二可折弯区域314。由于非折弯区域33与框体21粘贴，因此，非折弯区域33的折叠角度与框体21的折叠角度相同；第一可折弯区域312与侧部支撑件233粘贴，在第一可折弯区域312折叠时，第一可折弯区域312与侧部支撑件233的粘贴段会自然外张，通过侧部支撑件233能限定第一可折弯区域312外张的形状。由于第二可折弯区域314没有与中部支撑件231粘贴，且两个侧部支撑件233限定第二可折弯区域314相对的两侧，第二可折弯区域314在折叠过程中会有向中部支撑件231移动的趋势，通过中部支撑件231抵顶第二可折弯区域314，以限定第二可折弯区域314的形状。因此，通过侧部支撑件233、中部支撑件23和框体21形成的区域以及粘胶情况可以使柔性件30的可折弯区域31形成水滴形态。在可折弯区域31形成水滴形态后，每一框体21与侧部支撑件233之间的柔性件30形成外弯区，即柔性件30的每一非折弯区域33与第一可折弯区域312之间形成外弯区；中部支撑件231与两个侧部支撑件233之间的柔性件30形成内弯区，即柔性件30的第二可折弯区域314形成内弯区；所述外弯区的受力方向和大小不同于所述内弯区的受力方向和大小。
在对电子设备100的其他折弯方式中，还可以同时对两个框体21施加折弯的力，两个框体21分别带动两个转动组件253向靠近柔性件30的一侧转动，并通过转轴装置22以实现电子设备100的折弯。
当需要展平电子设备100时，向外拉开其中一框体21，使连接于两个框体21上的两个转动组件253朝相互远离的方向转动。具体地，对电子设备100的其中一框体21施加向外拉开的力，所述其中一框体21带动对应的转动件254相对于定位座251向远离柔性件30的一侧转动，转动件254的第二圆弧轨2541沿定位座251的第二圆弧槽2511相对转动，连接件256带动联动件264和对应的转动轴266一并相对于联动座261转动，且联动件264的导滑条2647在导滑槽2568中滑动、联动件264的第一导滑部2640自限位滑槽2330的第一限位段2330a滑动至第二限位段2330b，以及联动件264的第二导滑部2641在导滑槽2337中自第一止挡部2337a滑动至第二止挡部2337b；以带动对应的联动件264和对应的转动轴266一并转动；同时，连接件256带动第一圆弧轨2562转动地连接于对应的第一圆弧槽2335中，联动件264的转动带动对应的第一齿轮2651转动，通过齿轮组合265带动对应的两个第一齿轮2651同步转动，同步转动的第一齿轮2651带动对应的两个联动件264同步相互远离；同时，两个转动组件253相对于定位座251同步转动而相互远离，以带动两个侧部支撑件233同步相互远离而展平，使得转轴装置22展开，柔性件30的可折弯区域31随转轴装置22展开，直至柔性件30展平。
在上述过程中，每一转动轴266上的第一凸轮2710与第二凸轮2730之间的摩擦扭力之和和摩擦件276与垫片277及定位件275之间的摩擦扭力大于柔性件30的反弹力，以使两个侧部支撑件233之间相对定位在特定角度，能使两个框体21限位在130度至70度之间的特定角度。
在对电子设备100的其他折弯方式中，还可以同时对两个框体21施加向外拉开的力，两个框体21分别带动两个转动组件253相对于向远离柔性件30的一侧转动，并通过转轴装置22以实现电子设备100的展开。
本发明的电子设备100的转轴装置22通过转动组件25及联动组件26实现同步折弯或展开，其次转轴装置22在弯折状态时，第一导滑部2640止挡于限位滑槽2330的第一限位段2330a，防止转轴装置 22进一步弯折可能损坏柔性件30；转轴装置22在展平状态时，第一导滑部2640止挡于限位滑槽2330的第一限位段2330b，防止转轴装置22进一步展开可能损坏柔性件30；另外，由于限位机构27的弹性件274能提供较大的轴向力，使得第一凸轮2710与所述第二凸轮2730之间和摩擦件276与垫片277及定位件275之间的摩擦扭力；因此，由第一凸轮2710与所述第二凸轮2730之间具有较大的摩擦扭力，且摩擦件276与垫片277及定位件275之间也具有较大的摩擦扭力，使得摩擦扭力足够大，能实现电子设备100弯折限位在70度-130度之间的特定角度，实现整机的悬停功能。还有，转轴装置22的结构牢固，提升电子设备100的整机强度。
请一并参阅图29-图32，本发明的另一实施例的转轴装置22a的结构与上述其中一实施例中的转轴装置22的结构相似，不同之处在于，在另一实施例中的转轴装置22a的联动件264与侧部支撑件233通过止位滑槽与止位部的配合连接来取代限位滑槽2330与滑动部2640的配合连接，转轴装置22a的联动件264与侧部支撑件233通过所述止位滑槽与所述止位部的配合连接，能防止侧部支撑件231过度折叠或过度展平而损坏柔性屏。本实施例中，止位滑槽2338设于侧部支撑件233上，止位滑槽2338包括相互平行的第一止位滑槽2338a和第二止位滑槽2338b，第一止位滑槽2338a包括第一止位段2338c，第二止位滑槽2338b包括第二止位段2338d；止位部2648对应止位滑槽2338设于联动件264上；在两个侧部支撑件233呈完全折叠状态时，止位部2648定位于第一止位段2338c，以止挡侧部支撑件233进一步折叠而可能损坏柔性屏；在两个侧部支撑件233呈展平状态时，止位部2648定位于第二止位段2338d，以止挡侧部支撑件233展平后进一步反折而可能损坏柔性屏。
具体地，侧部支撑件233的背面对应联动件264处凸设限位部2336，限位部2336为弧形条，所述弧形条自侧部支撑板靠近定位座251的一侧向远离定位座251的一侧弯曲延伸；第一止位滑槽2338a及第二止位滑槽2338b分别设于限位部2336上并沿限位部2336的长度方向延伸；第一止位滑槽2338a及第二止位滑槽2338b的至少一端设置为开口状态，即第一止位滑槽2338a及第二止位滑槽2338b的至少一端没有端壁；由于第一止位滑槽2338a及第二止位滑槽2338b的至少一端无需设置端壁，从而能减少限位部2336的延伸长度，进而减小能减小侧部支撑件233的宽度，以使转轴装置22a的整体宽度变小，减小转轴装置22a占用电子装置的壳体的内部空间，有利于主板或电池等其他元件的布局。
优选地，第一止位滑槽2338a及第二止位滑槽2338b均为圆弧槽，相较于直线槽，所述圆弧槽所占用的长度较小，从而能减小限位部2336沿侧部支撑件233的宽度方向延伸的长度，以使侧部支撑件233的宽度减小，使得转轴装置22a的整体宽度变小，减小转轴装置22a占用电子装置的壳体的内部空间，有利于主板或电池等其他元件的布局。
第一止位段2338c较第二止位段2338d更靠近定位座，也就是第一止位段2338c靠近定位座251，第二止位段2338d远离定位座251。止位部2648包括相互间隔地设置于连杆2643的第一止位部2648a及第二止位部648b，第一止位部2648a滑动地容置于第一止位滑槽2338a，第二止位部2648b滑动地容置于第二止位滑槽2338b；在第一止位部2648a定位于第一止位段2338c时，两个侧部支撑件233呈完全折叠状态，第一止位部2648a与第一止位段2338c的定位能防止侧部支撑件233进一步折叠而损坏柔性屏；在第二止位部2648b定位于第二止位段2338d时，两个侧部支撑件233呈展平状态，第二止位部2648b与第二止位段2338d的定位能防止侧部支撑件233进一步展平而出现反折损坏柔性屏。

在一些实施例中,侧部支撑件233上的限位滑槽2339与转动件254上的导滑部2545可以互换，也就是导滑部可以设于侧部支撑板233靠近定位座251的一侧，限位滑槽可以设于转动件，所述导滑部滑动地穿设于所述限位滑槽中。
请参阅图42，本发明再一实施例中的转轴装置22c的结构与上述的另一实施例中的转轴装置22a的结构相似，不同之处在于：在转动轴装置22c的转动件254与侧部支撑件233通过止位滑槽与止位部的配合连接来取代在联动件264与侧部支撑件233的止位滑槽与止位部的配合连接；也部是在上述另一实施例中转轴装置22a的基础上省略联动件264与侧部支撑件233的止位滑槽与止位部的配合连接，而使转动件254与侧部支撑件233通过止位滑槽与止位部的配合连接。本实施例中，止位滑槽2338设于侧部支撑件233上，止位滑槽2338包括相互平行的第一止位滑槽2338a和第二止位滑槽2338b，第一止位滑槽2338a包括第一止位段2338c，第二止位滑槽2338b包括第二止位段2338d；止位部2548对应止位滑槽2338设于转动件254上；在两个侧部支撑件233呈完全折叠状态时，止位部2548定位于第一止位段2338c，以止挡侧部支撑件233进一步折叠而可能损坏柔性屏；在两个侧部支撑件233呈展平状态时，止位部2548定位于第二止位段2338d，以止挡侧部支撑件233展平后进一步反折而可能损坏柔性屏。
具体地，侧部支撑件233的背面对应转动件254处凸设限位部2336，限位部2336为弧形条，所述弧形条自侧部支撑板靠近定位座251的一侧向远离定位座251的一侧弯曲延伸；第一止位滑槽2338a及第二止位滑槽2338b分别设于限位部2336上并沿限位部2336的长度方向延伸；第一止位滑槽2338a及第二止位滑槽2338b的至少一端设置为开口状态，即第一止位滑槽2338a及第二止位滑槽2338b的至少一端没有端壁；由于第一止位滑槽2338a及第二止位滑槽2338b的至少一端无需设置端壁，从而能减少限位部2336的延伸长度，进而减小能减小侧部支撑件233的宽度，以使转轴装置22c整体宽度变小，减小转轴装置22c占用电子装置的壳体的内部空间，有利于主板或电池等其他元件的布局。
优选地，第一止位滑槽2338a及第二止位滑槽2338b均为圆弧槽，相较于直线槽，所述圆弧槽所占用的长度较小，从而能减小限位部2336沿侧部支撑件233的宽度方向延伸的长度，以使侧部支撑件233的宽度减小，使得转轴装置22c的整体宽度变小，减小转轴装置22c占用电子装置的壳体的内部空间，有利于主板或电池等其他元件的布局。
第一止位段2338c相较于第二止位段2338d更靠近定位座251，也就是第一止位段2338c靠近定位座251，第二止位段2338d远离定位座251。止位部2548包括相互间隔地设置于连接部2543的第一止位部2548a及第二止位部2548b，第一止位部2548a滑动地容置于第一止位滑槽2338a，第二止位部2548b滑动地容置于第二止位滑槽2338b。在第一止位部2548a定位于第一止位段2338c时，两个侧部支撑件233呈完全折叠状态，第一止位部2548a与第一止位段2338c的定位能防止侧部支撑件233进一步折叠而损坏柔性屏；在第二止位部2548b定位于第二止位段2338d时，两个侧部支撑件233呈展平状态，第二止位部2548b与第二止位段2338d的定位能防止侧部支撑件233进一步展平而出现反折损坏柔性屏。
限位部2336包括相对的两个侧面，第一止位滑槽2338a及第二止位滑槽2338b分别设于所述两个侧面，第一止位部2548a与第二止位部2548b之间具有间隙2548c，限位部2336滑动地容置于所述间隙2548c中，第一止位部2548a滑动地容置于第一止位滑槽2338a，第二止位部2548a滑动地容置于第二止位滑槽2338b中。本实施例中，第一止位滑槽2338a设于限位部2336的一侧面靠近侧部支撑板2331的一侧，第一止位滑槽2338a为弧形槽，所述弧形槽向远离支撑板2331的一侧变曲，第一止位滑槽2338a相对的两端分别穿通限位部2336相对的两端面，第一止位滑槽2338a靠近限位部2336的一端与限位部2336形成第一止位段2338c；第二止位滑槽2338b设于限位部2336相对的另一侧面远离侧部支撑板2331的一侧，第二止位滑槽2338b为弧形槽，所述弧形槽向远离支撑板2331的一侧变曲，第二止位滑槽2338b靠近定位座251的一端穿通限位部2336的端面，第二止位滑槽2338b远离定位座251的一端延伸至靠近限位部2336的端面以形成第二止位段2338d。
如图42所示，第一止位部2548a及第二止位部2548b均设置于连接部2543面朝侧部支撑件233的一侧，第一止位部2548a相较于第二止位部2548b更远离第一转动部2540，也就是第一止位部2548a相较于第二止位部2548b更远离定位座251。第一止位部2548a与第二止位部2548b之间具有间隙2548c，限位部2336可滑动地插设于间隙2548c中，第一止位部2548a滑动地容置于第一止位滑槽2338a中，第二止位部2548b滑动地容置于第二止位滑槽2338b中。具体地，第一止位部2548a包括凸设于连接部2543的第一止位块，所述第一止位块用于滑动地容置于第一止位滑槽2338a中，且所述第一止位块能止挡于第一止位段2338c；第二止位部2548b为凸设于连接部2543的第二止位块，所述第二止位块用于滑动地容置于第二止位滑槽2338b中，且所述第二止位块能止挡于第二止位段2338d。优选地，所述第一止位块与第一止位滑槽2338a的内表面接触的表面设置为圆弧面，以使第一止位部2548a与第一止位滑 槽2338a的滑动更顺畅；所述第二止位块与第二止位滑槽2338b的内表面接触的表面设置为圆弧面，以使第二止位部2548b与第二止位滑槽2338b的滑动更顺畅。
本发明的再一实施例中的转轴装置22c组装完成后，转动件254的第二圆弧轨2541转动地容置于定位座251的第二圆弧槽2511中，转动件254的第二转动部2542容置于连接件256的收容口2561中，第二转动部2542转动地连接于连接件256。侧部支撑件233的限位部2336可滑动地插设于转动件254的间隙2548c中，且限位部2336位于第一止位部2548a与第二止位部2548b之间的间隙2548c中，第一止位部2548a可滑动地容置于第一止位滑槽2338a中，第二止位部2548b可滑动地容置于第二止位滑槽2338b中。连接件256的第一圆弧轨2562可转动地容置于侧部支撑件233的第一圆弧槽2335中。联动件264的套筒2642通过转动轴连接于联动座261，联动件264的连杆2643滑动地插设于连接件256的导滑空间2566中。
需要说明的是为了撰写方便，图42中的转轴装置22c仅示意了定位座251、联动座261、一个侧部支撑件233、一个转动件254、一个连接件256及一个联动件264的示意结构，其他部件省略。
转轴装置22c在折叠过程中，一对转动件254和一对连接件256相对于定位座251同步转动以相互靠近，一对联动件264相对于联动座261同步转动以相互靠近，同时，一对侧部支撑件233同步相互折弯。具体地，转动件254相对于定位座251通过第二圆弧轨2541与第二圆弧槽2511相对转动，以带动连接件256相对于定位座251转动；连接件256的转动以带动联动件264对应的转动轴266转动，以使转动轴上的第一齿轮转动，以带动对应的第二齿轮转动，从而实现两个联动件的同步转动而相互靠近，每一联动件264的连杆2643在导滑空间2566中滑动。第一止位部2548a在第一止位滑槽2338a中向第一止位段2338c滑动，直至第一止位部2548a止挡于第一止位段2338c，第二止位部2548b在第二止位滑槽2338b中向远离第二止位段2338d滑动，以实现两个侧部支撑件233的相互折弯。
转轴装置22c在展平过程中，一对转动件254和一对连接件256相对于定位座251同步转动以相互远离，一对联动件264相对于联动座261同步转动以相互远离，同时，一对侧部支撑件233同步相互展平。具体地，转动件254相对于定位座251通过第二圆弧轨2541与第二圆弧槽2511相对转动，以带动连接件256相对于定位座251转动；连接件256的转动以带动联动件264对应的转动轴转动，以使转动轴上的第一齿轮转动，以带动对应的第二齿轮转动，从而实现两个联动件的同步转动而相互远离，每一联动件264的连杆2643在导滑空间2566中滑动。第一止位部2548a在第一止位滑槽2338a中远离第一止位段2338c滑动，第二止位部2548b在第二止位滑槽2338b中朝向第二止位段2338d滑动，直至第二止位部2548b止挡于第二止位段2338d，以实现两个侧部支撑件233的相互展平。
在其他实施例中，可以将上述再一实施例中的转轴装置22c的转动件254的止位部2548与侧部支撑件233的止位滑槽2338位置互换，也就是转动件254上设有止位滑槽，侧部支撑件233上设有对应所述止位滑槽的止位部。
以上是本申请实施例的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
