如图10至图14所示，第一圆弧槽228的轴心线、第二圆弧槽2655的轴心线及第三圆弧槽2672的轴心线相互间隔平行，并平行于折叠装置23的折叠轴线。具体地，第一圆弧槽228的轴心线与对应的第一转动轴A1的轴心线重合，第二圆弧槽2655的轴心线与对应的第二转动轴A2的轴心线重合，第三圆弧槽2672的轴心线与对应的第三转动轴A3的轴心线重合；第一转动轴A1、第二转动轴A2及第三转动轴A3均为虚轴，且第一转动轴A1、第二转动轴A2及第三转动轴A3平行于折叠装置23的折叠轴线。因此，支撑机构24通过虚轴转动连接，能减少占用两个框体22的第一收容槽221及第二收容槽223所围成安装空间，方便收容其他元件，且能减轻折叠壳体20的整体重量，并能减少制造成本等。
在折叠壳体20展平时，连接框28容置于两个框体22的第一收容槽221及第二收容槽围成的安装空间中，第一支撑件261的正面、第二支撑件265的正面，以及框体22的正面220位于同一平面，柔性件30展平在所述平面上。第一圆弧槽228的轴心线、第二圆弧槽2655的轴心线及第三圆弧槽2627的轴心线位于同一平面上，即第一转动轴A1的轴心线、第二转动轴A2的轴心线及第三转动轴A3的轴心线位于同一平面上。具体地，第一圆弧槽228的轴心线、第二圆弧槽2655的轴心线及第三圆弧槽2627的轴心线位于平行于柔性件的同一平面上；本实施例中，第一转动轴A1的轴心线、第二转动轴A2的轴心线及第三转动轴A3的轴心线位于柔性件30的背部，即第一转动轴A1的轴心线、第二转动轴A2的轴心线及第三转动轴A3的轴心线所在的平面间隔平行于柔性件30的背面；优选地，第一支撑板2611的背面及第二支撑板2651的背面共面，第一转动轴A1的轴心线、第二转动轴A2的轴心线及第三转动轴A3的轴心线位于所述共面上。第一支撑件261与支撑座体267之间的转动轴的轴心线较连杆件251与连杆基座255之间的转动轴的轴心线更靠近第一支撑件261的正面；即第一支撑件261与支撑座体267之间的第三转动轴A3的轴心线较连杆件251与连杆基座255之间的转动轴的轴心线更靠近第一支撑件261的正面。即第三转动轴A3的轴心线较连杆件251与连杆基座255之间的转动轴的轴心线更靠近柔性件30。每一连杆件251的第二端杆2513被支撑于对应的连杆基座255的限位面2555上，以阻止连杆件251进一步向背部转动，从而防止折叠装置23反折而损坏柔性件30；此时，每一连杆件251的导轴2517位于对应的滑槽2617远离柔性件30的一端。
请一并参阅图15至图20，折叠移动终端100时，对移动终端100的其中一框体22施加折弯的力，使得所述其中一框体22向另一框体22转动，以带动连接于所述其中一框体22的连杆件251转动。具体地，所述其中一框体22的转动使得连杆件251的第一端杆2511在对应的导槽226内滑动，且连杆件251的连接轴2516沿对应的轴孔2553转动，连杆件251的导轴2517在对应的滑槽2617内向靠近柔性件30的一端滑动并转动地抵推滑槽2617的内壁，使得对应的第一支撑件261随连杆件251相对于支撑座体267转动；由于第一支撑件261与对应的第二支撑件265之间通过第二圆弧轨2613与第二圆弧槽2655转动地连接，第二支撑件265与对应的框体22之间通过第一圆弧轨2653与第一圆弧槽228转动地连接，因此，所述其中一框体22的转动和第一支撑件261的转动共同带动第二支撑件261相对于第一支撑件261及所述其中一框体22转动。按同样的方法将另一框体22施加折弯的力，使得所述另一框体22向所述其中一框体22转动，以带动连接于所述另一框体22的连杆件251转动；具体地，所述另一框体22的转动使得连杆件251的第一端杆2511在对 应的导槽226内滑动，且连杆件251的连接轴2516沿对应的轴孔2553转动，连杆件251的导轴2517在对应的滑槽2617内向靠近柔性件30的一端滑动并转动地抵推滑槽2617的内壁，使得对应的第一支撑件261随连杆件251相对于支撑座体267转动；由于第一支撑件261与对应的第二支撑件265之间通过第二圆弧轨2613与第二圆弧槽2655转动地连接，第二支撑件265与对应的框体22之间通过第一圆弧轨2653与第一圆弧槽228转动地连接，因此，所述另一框体22的转动和第一支撑件261的转动共同带动第二支撑件261相对于第一支撑件261及所述其中一框体22转动，以实现折叠装置23的折叠。由于连杆件251的连接轴2516与轴孔2553之间的转动轴的轴心线较对应的第三转动轴A3的轴心线远离柔性件30，且导轴2517滑动并转动地设于对应的滑槽2617内，因此，在折叠装置23的折叠过程中，第一支撑件261的转动角度大于第二支撑件265的转动角度，即同一支撑组件26的第一支撑板2611的转动角度大于第二支撑板2651的转动角度；使得支撑机构24的两个支撑组件26之间围成锥形的容置空间27。具体地，两个支撑组件26的第一支撑件261间隔相对，第二支撑件265间隔相对，且两个第一支撑件261之间的间隔大于第二支撑件265之间的间隔，即两个第一支撑板2611之间的间隔大于两个第二支撑板2651之间的间隔。在折叠装置23的折叠过程中，柔性件30的可折弯区域31随折叠装置23弯曲形成容置于容置空间27中的弯折部301，弯折部301的横截面呈水滴形，柔性件30的两个非折弯区域33的正面相贴合，从而使移动终端100在折叠状态下的整体厚度减少。每一第一支撑件261上的第一避位缺口2617及第二避位缺口2618用于分别避让对应的支撑座体267及连杆基座255，以避免支撑座体267及连杆基座255抵顶对应的第一支撑板2611。
在对移动终端100的其他折弯方式中，可以同时对两个框体22施加折弯的力，使得两个框体20相互靠近，以带动对应的连杆件251转动而相互靠近，框体22和连杆件251的转动带动第一支撑件261及第二支撑件265转动，以实现折叠装置23的折叠，柔性件30随折叠装置23折叠以实现移动终端100的折弯。
如图16至图20所示，在折叠装置23处于折弯状态时，每一支撑机构24的第一支撑件261及第二支撑件265容置于两个框体22的第一收容槽221及第二收容槽223围成的安装空间中；折叠装置23的两个第一圆弧槽228的轴心线之间的间隔小于两个所述第二圆弧槽2655的轴心线之间的间隔，两个第二圆弧槽2655的轴心线之间的间隔小于两个所述第三圆弧槽2672之的轴心线之间的间隔；即两个第一转动轴A1的轴心线之间的间隔小于两个第二转动轴A2的轴心线之间的间隔，两个第二转动轴A2的轴心线之间的间隔小于两个第三转动轴A3的轴心线之间的间隔。
如图11至图14所示，当需要展平移动终端100时，向外拉开其中一框体22，使得所述其中一框体22朝远离另一框体22转动，以带动连接于所述其中一框体22的连杆件251转动。具体地，所述其中一框体22的转动使得连杆件251的第一端杆2511在对应的导槽226内滑动，且连杆件251的连接轴2516沿对应的轴孔2553转动，连杆件251的导轴2517在对应的滑槽2617内向远离柔性件30的一端滑动并转动地抵推滑槽2617的内壁，使得对应的第一支撑件261随连杆件251相对于支撑座体267转动；所述其中一框体22的转动和第一支撑件261的转动共同带动第二支撑件261相对于第一支撑件261及所述其中一框体22转动。按相同的方法将另一框体22施加展平的力，使得所述另一框体22朝远离所述其中一框体22转动，以带动连接于所述另一框体22的连杆件251转动；具体地，所述另一框体22的转动使得连杆件251的第一端杆2511在对应的导槽226内滑动，且连杆件251的连接轴2516沿对应的轴孔2553转动，连杆件251的导轴2517在对应的滑槽2617内向远离柔性件30的一端滑动并转动地抵推滑槽2617的内壁，使得对应的第一支撑件261随连杆件251相对于支撑座体267转动；所述另一框体22的转动和第一支撑件261的转动共同带动对应的第二支撑件261相对于第一支撑件261及所述其中一框体22转动，以实现折 叠装置23的展平。在折叠装置23的展平过程中，柔性件30的可折弯区域31随折叠装置23展平。
在对移动终端100的其他展平方式中，可以同时对两个框体22施加展平的力，使得两个框体20相互远离，以带动对应的连杆件251转动而相互远离，框体22和连杆件251的转动带动第一支撑件261及第二支撑件265转动，以实现折叠装置23的展平，柔性件30随折叠装置23展平以实现移动终端100的展平。
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。
