请一并参阅图1-图5,将安装完成的折叠装置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及折叠装置22的正面。具体地,可折弯区域31贴附于折叠装置22的正面,两个非折弯区域33分别贴附于两个框体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,折叠装置22保持展平状态;另外,联动件264的导滑部2640滑 动地容置于对应的侧部支撑件233的限位滑槽2330中,折叠装置22在弯折状态时,导滑部2640止挡于限位滑槽2330的第一限位段2330a,防止折叠装置22进一步弯折可能损坏柔性件30;折叠装置22在展平状态时,导滑部2640止挡于限位滑槽2330的第一限位段2330b,防止折叠装置22进一步展开可能损坏柔性件30。
请一并参阅图1-图4及图17-图28,弯折电子设备100时,对电子设备100的两个框体21中的至少其中一个施加折弯的力,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实现折叠装置22的折弯,柔性件30的可折弯区域31随支撑组件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围绕对应的第一转动轴266转动,以使联动件264的导滑条2647在导滑槽2568中滑动、且联动件264的导滑部2640自限位滑槽2330的第二限位段2330b滑动至第一限位段2330a,以带动对应的联动件264围绕对应的第一转动轴266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的第二齿轮2652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,直至折叠装置22呈折弯状态;柔性件30的可折弯区域31随折叠装置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。
在弯折电子设备100的过程中,第一凸轮2710抵推对应的第二凸轮2730以使抵持件273相对于联动件264沿第一转动轴266的轴线方向移动,每一第一转动轴266上的第一凸轮2710与第二凸轮2730之间的摩擦扭力及每一第二转动轴267上的第一凸轮2710与第二凸轮2730之间的摩擦扭力抵抗柔性件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。
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分别带动两个转动机构253向靠近柔性件30的一侧转动,并通过折叠装置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围绕对应的第一转动轴266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;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的第二齿轮2652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,使得折叠装置22展开,柔性件30的可折弯区域31随折叠装置22展开,直至柔性件30展平。
在展平电子设备100的过程中,每一第一转动轴266上的第一凸轮2710与第二凸轮2730之间的摩 擦扭力及每一第二转动轴267上的第一凸轮2710与第二凸轮2730之间的摩擦扭力抵抗柔性件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分别带动两个转动机构253相对于向远离柔性件30的一侧转动,并通过折叠装置22以实现电子设备100的展开。
本申请的电子设备100的折叠装置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,折叠装置22在弯折状态时,导滑部2640止挡于限位滑槽2330的第一限位段2330a,防止折叠装置22进一步弯折可能损坏柔性件30;折叠装置22在展平状态时,导滑部2640止挡于限位滑槽2330的第二限位段2330b,防止折叠装置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之间的摩擦扭力足够大;从而能实现电子设备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。还有,折叠装置22的结构牢固,提升电子设备100的整机强度。
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。
