如图2所示，所述电子装置100还包括分别贴合于第一框体21及第二框体23的正面的两个平整板60，以及贴合于柔性屏30的支撑片70。所述支撑片70是柔性支撑片，所述支撑片70可以是薄金属片如铜箔、液态金属片、记忆合金片、塑胶片或其他符合材料制成的薄片。本实施例中，所述支撑片70是薄钢片。
请一并参阅图8至图14，组装所述电子装置100时，将第一框体21与第二框体23齐平，使第一框体21的第一收容槽211与第二框体23的第二收容槽231围成一空间；将转动装置25放置于所述空间内，使一对所述转动组合250的安装板2554分别收容于第一安装槽213及第二安装槽233内，即其中一安装板2554穿过通槽2455插入连接槽2417内，另一安装板2554装于第二框体23的第二安装槽233，若干锁固件分别穿过安装板2554上的安装孔2555锁固于对应的锁固孔连接孔2418内。此时，第一框体21与第二框体23呈展平状态，每一转动件255定位于对应的定位杆2512上，即定位杆2512定位于转动件255背面的所述转动块2551与所述安装板2554之间的定位槽内。将两个平整板60分别贴合于第一框体21及第二框体23的正面，两个所述平整板60的正面处于同一平面上。此时，弹性件243处于弹性压缩状态且抵持于滑块2411与第一框体21之间，滑块2411的抵顶面2413抵顶所述台阶块216的止挡面2162，滑块2411与两个定位块2453的挡止面2457之间存在间隔A。采用治具固定住第二框体23，推动第一框体21向转动装置25邻近，直至压合件245的定位块24533的挡止面2457抵接于滑块2411，滑块2411的抵顶面2413与台阶块216的止挡面2162之间的间隙变为A，弹性件243进一步被压缩；将支撑片70的正面贴合于柔性屏30的背面，再将支撑片70的背面贴合固定于平整板60的正面，贴接完后松开治具并解除对第一框体21的推力，此时受弹性件243推力作用第一框体21向远离转动装置25的一侧滑动，滑块2411与两个定位块2453的挡止面2457之间恢复间隔A，柔性屏30被往远离转动装置25的一侧拉伸距离A，即电子装置100组装完成。
请参阅图15，当电子装置100在展平状态时，弹性件243弹性抵推第一框体21向远离转动装置25的一侧滑动，滑块2411的抵顶面2413抵顶所述台阶块216的止挡面2162,滑块2411与两个定位块2453的挡止面2457之间存在间隔，使固定于第一框体21及第二框体23上的柔性屏向外拉伸，能防止柔性屏30的可折弯区域31出现折痕或凸起。请参阅图16，需要折弯所述电子装置100时，对电子装置100的第一框体21及第二框体23至少其中一个施加折弯的力F1，如图16中对第二框体23施加折弯的力F1，能使连接于第一框体21和第二框体23上的转动件255朝相互邻近的方向转动。具体的，固定于第二框体23上的转动件255朝第一框体21的方向逆时钟转动，带动所述转动件255的驱动齿轮2570逆时钟转动，所述驱动齿轮2570带动对应的第一传动齿轮2561顺时钟转动，所述第一传动齿轮2561带动对应的第二传动齿轮2563逆时钟转动，所述第二传动齿轮2563带动另一第二传动齿轮2563顺时钟，所述另一第二传动齿轮2563带动对应的另一第一传动齿轮2561逆时钟，所述另一第一传动齿轮2561带动对应的另一驱动齿轮2570顺时钟，即使转动装置25联动，从而使第一框体21与第二框体23相互邻近，以完成弯折。此时，柔性屏30就不受拉力，是由于柔性屏30弯折后，虽然第一框体21还是被推向端部，但是推力方向是沿着第一框体21，此时柔性屏30其实是被抬高的，因此，柔性屏30的可折弯区域31不受拉。本申请的柔性屏30在展平状态下第一框体21滑动方向和屏折弯区31的展平方向 平行，此时柔性屏30受到拉力；而柔性屏30弯折后，柔性屏30的可折弯区域31具有冗余长度，即柔性屏30不再收到拉伸作用；即电子装置100从展平状态至弯折状态的过程中，柔性屏30逐渐被被抬高，柔性屏30从受到拉力作用到受到的拉力逐渐减少，最后柔性屏30不再受到拉力作用，使柔性屏30避免长期受拉力作用影响屏寿命。
在折弯所述电子装置100时，也可以对第一框体21施加折弯的力，固定连接所述第一框体21上的转动件255朝向第二框体23顺时钟转动以带动对应的驱动齿轮2570顺时钟转动，所述驱动齿轮2570带动对应的第一传动齿轮2561逆时钟转动，所述第一传动齿轮2561带动对应的第二传动齿轮2563顺时钟转动，所述第二传动齿轮2563带动另一第二传动齿轮2563逆时钟转动，所述另一第二传动齿轮2563带动对应的另一第一传动齿轮2561顺时钟转动，所述另一第一传动齿轮2561带动对应的另一驱动齿轮2570逆时钟转动，即使转动装置25联动，从而使第一框体21与第二框体23相互邻近，以完成弯折。
电子装置100由弯折至展平时，对电子装置100的第一框体21及第二框体23至少其中一个施加展平的力F2，如图13中对第二框体23施加展平的力F2，能使连接于第一框体21和第二框体23上的转动件255朝相互远离的方向转动。具体的，固定于第二框体23上的转动件255朝远离第一框体21的方向顺时钟转动，带动所述转动件255的驱动齿轮2570顺时钟转动，所述驱动齿轮2570带动对应的第一传动齿轮2561逆时钟转动，所述第一传动齿轮2561带动对应的第二传动齿轮2563顺时钟转动，所述第二传动齿轮2563带动另一第二传动齿轮2563逆时钟转动，所述另一第二传动齿轮2563带动对应的另一第一传动齿轮2561顺时钟转动，所述另一第一传动齿轮2561带动对应的另一驱动齿轮2570逆时钟转动，即使转动装置25联动，从而使第一框体21与第二框体23相互远离，以完成展平
也可以对第一框体21施加展平的力，固定于第一框体21上的转动件255朝远离第二框体23的方向逆时钟转动，使固定连接转动件255上的驱动齿轮2570逆时钟转动，所述驱动齿轮2570带动对应的第一传动齿轮2561顺时钟转动，所述第一传动齿轮2561带动对应的第二传动齿轮2563逆时钟转动，所述第二传动齿轮2563带动另一第二传动齿轮2563顺时钟转动，所述另一第二传动齿轮2563带动对应的另一第一传动齿轮2561逆时钟转动，所述另一第一传动齿轮2561带动对应的另一驱动齿轮2570顺时钟转动，即使转动装置25联动，从而使第一框体21与第二框体23相互远离，以完成展平。
电子装置100由于采用直齿轮啮合的方式联动，相比于采用斜齿轮啮合联动的方式而言，不需要很高的制造精度，可有效地降低生产成本，提升生产效率。
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。
