在其他的使用方式中,可以将两个连接件256朝相向方向一同转动,每一连接件256通过对应的第一转动件254的第二圆弧轨2541与定位座251对应的第二圆弧槽2511相对转动,及对应的第二转动件255的第三圆弧轨2552与定位座251的第三圆弧槽2512相对转动,以带动限位机构27的联动件264沿对应的转动轴266转动;同时,两个连接件256同步带动第一圆弧轨2562转动地连接于侧部支撑件233对应的第一圆弧槽2334中,第一转动件254上的第一限位部2540在对应的侧部支撑件233的第一限位槽2336中滑动并转动,以使第一限位部2540从第一定位段2336a移动至第二定位段2336b;联动件264的转动带动对应的第一齿轮转动,通过齿轮组合265带动对应的两对第一齿轮同步转动,同步转动的第一齿轮带动对应的联动件264同步相互靠拢,联动件264上的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第一定位段2567a移动至第二定位段2567b;同时,限位机构27相对两侧的转动机构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,直至两个侧部支撑件233与定位座251围成横截面成水滴状。
当转轴装置22由完全弯折状态进行展开时,将其中一连接件256相对于定位座251朝远离另一连接件256展开,所述其中一连接件256带动第一转动件254的第二圆弧轨2541在定位座251的第二圆弧槽2511内转动,及带动第二转动件255的第三圆弧轨2552在定位座251的第三圆弧槽2512内转动,第一转动件254的第一限位部2540在对应的第一限位槽2336中滑动并转动,且第一限位部2540从第二限位段2336b移动至第一限位段2336a;以带动对应的联动件264沿转动轴266转动,联动件264上的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第二定位段2567b移动至第一定位段 2567a。联动件264的转动带动对应的第一齿轮转动,通过齿轮组合265带动对应的两个第一齿轮同步转动,同步转动的第一齿轮带动对应的两个联动件264同步相互远离;同时,限位机构27相对两侧的转动机构253相对于定位座251同步转动而相互远离,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,以带动两个侧部支撑件233同步相互展开,直至两个侧部支撑件233与定位座251呈展平状。
在侧部支撑件233相对于定位座251展平过程中,第一限位部2540自第一限位槽2336的第二限位段2336b移动至第一限位段2336a,转轴2648从导滑槽2567的第二定位段2567b移动至第一定位段2567a;定位座251相对两侧的第一转动轴心线C1相互远离,定位座251相对两侧的第二转动轴心线C2相互远离,直至两个侧部支撑件233顺利展平。每一转动轴266上的第一凸轮及第二凸轮2730上的轴向力等于弹性件274的弹力;第一凸轮与第二凸轮2730之间的摩擦阻力能使两个侧部支撑件233限位在130度至70度之间的特定角度。
在其他的使用方式中,可以将两个连接件256朝相互远离的方向一同转动,每一连接件256带动第一转动件254的第二圆弧轨2541沿定位座251的第二圆弧槽2511相对转动,及带动对应的第二转动件255的第三圆弧轨2552与定位座251的第三圆弧槽2512相对转动,以带动限位机构27的联动件264沿对应的转动轴266转动;同时,两个连接件256同步带动第一圆弧轨2562转动地连接于侧部支撑件233对应的第一圆弧槽2334中,第一转动件254上的第一限位部2540在对应的侧部支撑件233的第一限位槽2336中滑动并转动,以使第一限位部2540从第二限位段2336b移动至第一限位段2336a;联动件264的转动带动对应的第一齿轮转动,通过齿轮组合265带动对应的第一齿轮同步转动,同步转动的第一齿轮带动对应的联动件264同步相互远离,联动件264上的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第二定位段2567b移动至第一定位段2567a;同时,限位机构27相对两侧的转动机构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,直至两个侧部支撑件233的正面与定位座251的正面齐平。
在一些实施例中,第一转动件254上的第一限位部2540与侧部支撑件233上的第一限位槽2336可以互换,也就是第一限位槽2336可以设于第一转动件254上,第一限位部2540可以固定于侧部支撑件2334,第一限位部2540滑动并转动地插设于第一限位槽2336。具体地,在第一转动件254面朝限位块2335的侧面设有限位槽,在侧部支撑件233的限位块2335设有能活动地插设于所述限位槽的限位轴,在转轴装置22弯折或展开的过程中,所述限位轴在所述限位槽滑动并转动。

请一并参阅图1-图8,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的正面及定位座251的正面2311共面。柔性屏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,可折叠区域31正对转轴装置22,两个非折叠区域33分别正对两个框体21的正面。当柔性屏30处在展平状态时,定位座251的正面与两个侧部支撑件233的正面齐平,第一凸轮与第二凸轮2730相互贴合,以限定两个侧部支撑件233保 持展平状态;由于侧部支撑件233的正面2331与定位座251的正面共面,因此,柔性屏30在展平时不会受到段差处的冲击,柔性屏30不会出现彩点、亮点等不良问题,保证柔性屏30的可靠性,同时,也提升柔性屏30的触摸手感,提高用户使用体验;另外,第一转动件254与侧部支撑件256之间通过第一限位槽2336与第一限位部2540配合连接,联动件264与对应的连接件256之间通过转轴2648与导滑槽2567配合连接,侧部支撑件233与连接件256之间通过第一圆弧轨2562与第一圆弧槽2334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,有利于电子设备100的小型化。
请一并参阅图15-图26,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叠的力,使连接于两个框体21的转动机构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的折叠,柔性屏30的可折叠区域31随转轴装置22弯折。具体地,如对其中一框体21施加折叠的力,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向靠近柔性屏30的一侧转动,具体地,第一转动件254的第二圆弧轨2541与定位座251的第二圆弧槽2511相对转动;第二转动件255相对于定位座251向靠近柔性屏30的一侧转动,具体地,第二转动件255的第三圆弧轨2552与定位座251的第三圆弧槽2512相对转动;第一转动件254上的第一限位部2540在第一限位槽2336中滑动并转动,且第一限位部2540从第一限位段2336a移动至第二限位段2336b,以带动对应的联动件264沿转动,联动件264上的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第一定位段2567a移动至第二定位段2567b。联动件264的转动带动对应的第一齿轮转动,通过齿轮组合265带动对应的两个第一齿轮同步转动,同步转动的第一齿轮带动两对联动件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2334中,限位机构27相对两侧的转动机构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呈折叠状态;柔性屏30的可折叠区域31随转轴装置22弯折,直至柔性屏30的两个非折叠区域33的正面相互贴合,可折叠区域31弯折成水滴状,从而实现电子设备100的无缝折叠。
在弯折电子设备100的过程中,每一转动轴266上的第一凸轮与第二凸轮2730之间的摩擦扭力抵抗柔性屏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,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,并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,第一转动件254的第二圆弧轨2541沿定位座251的第二圆弧槽2511相对转动及第二转动件255的第三圆弧轨2552沿定位座251的第三圆弧槽2512相对转动,同时,第一转动件254的第一限位部2540在对应的第一限位槽2336中滑动并转动,且第一限位部2540从第二限位段2336b移动至第一限位段2336a;以带动对应的联动件264沿转动轴266转动,联动件264上的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第二定位段2567b移动至第一定位段2567a;以带动对应的联动件264沿转动轴266转动,联动件264的转轴2648在对应的导滑槽2567中转动并滑动,且转轴2648从第二定位段2567b移动至第一定位段2567a;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,联动件264的转动带动对应的第一齿轮转动,通过齿轮组合265带动对应的两对第一齿轮同步转动,同步转动的第一齿轮带动对应的两对联动件264同步相互远离;同时,限位机构27相对两侧的转动机构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。
在展平电子设备100的过程中,每一转动轴266上的第一凸轮与第二凸轮2730之间的摩擦扭力之和抵抗柔性屏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。
本申请的电子设备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,第一转动件251与侧部支撑件233之间通过弧形的第一限位槽2336与第一限位部2540配合连接,联动件264与连接件256之间通过弧形的导滑槽2567与转轴2648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,由于限位机构27的弹性件274能提供较大的轴向力,使得第一凸轮与所述第二凸轮2730之间具有较大的摩擦扭力;因此,由第一凸轮与第二凸轮2730之间的摩擦扭力形成的转轴装置22的总摩擦扭力足够大,能实现电子设备100弯折限位在70度至130度之间的特定角度,实现整机的悬停功能。另外,转轴装置22的结构牢固,提升电子设备100的整机强度。
