在弯折电子设备100的过程中,柔性屏30的可折叠区域31弯折围成水滴形,减少弯折后的可折叠区域31的占空比,从而能减小电子设备100的整体厚度。
在对电子设备100的其他折叠方式中,还可以同时对两个框体21施加折叠的力,两个框体21分别带动两个转动机构253向靠近柔性屏30的一侧转动,且带动两个从动件262向靠近柔性30的一侧转动,并通过转轴装置22以实现电子设备100的折叠。
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上的两个转动机构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带动对应的第一转动件254相对于定位座251向远离柔性屏30的一侧转动,所述其中一框体21带动对应的第二转动件255相对于定位座251向远离柔性屏30的一侧转动,及所述其中一连接件256带动侧部支撑件233相对于定位座251移动,以使侧部支撑件233带动从动件262相对于定位座251转动,且从动件262上的导滑轨2621在导滑槽2336中滑动。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2334中,以使相对两侧的从动件262相对于转动而相互展开,以带动两个侧部支撑件233相互展开,直至两个侧部支撑件233与定位座251呈展平状,柔性屏30的可折叠区 域31随转轴装置22展开,直至柔性屏30展平。
在对电子设备100的其他折叠方式中,还可以同时对两个框体21施加向外拉开的力,两个框体21分别带动两个转动机构253及两个从动件262相对于向远离柔性屏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通过第一转动组件25及从动组件26实现折叠或展开,由于第一转动件254与连接件256之间的第一转动轴心线C1与第二转动件255与连接件256之间的第二转动轴心线C2平行错位,从动件262与侧部支撑件233之间通过倾斜的导滑槽2336与导滑轨2621配合连接,因此,能使转轴装置22中各元件间的连接更紧凑,从而减小转轴装置22的整体宽度,降低占用壳体20的内部空间,有利于主板或电池等其他元件的布局;其次,转轴装置22的结构牢固,提升电子设备100的整机强度。
