本实施例中,所述正面指与柔性屏30的出光面朝向相同的面,背面指与柔性屏30的出光面朝向背离的面。电子设备100例如是,但不局限于手机、平板电脑、显示器、液晶面板、OLED面板、电视、智慧手表、VR头戴显示器、车载显示器等其它任何具有显示功能的产品和部件。本发明实施例的描述中的“连接”是包括直接连接和间接连接两种情况,比如A和B连接包括A和B直接连接或者通过第三个元件C或更多的其他元件连接。连接还包括一体化连接和非一体化连接两种情况,一体化连接是指A和B是一体形成并连接,非一体化连接是指A和B是非一体化形成并连接。
本发明的电子设备100的转轴装置22的支撑组件28设置于转动组件23及扭力组件25上,转动件233可转动地连接于第一基座231与支撑组件28之间,转轴安装件251沿转轴的轴向滑动地连接于第一基座231,转动件233与转轴安装件251之间通过第一凸轮2330与第一抵顶凸轮2510可转动地抵持,第一弹性件241弹性抵推转轴安装件251抵顶转动件233,使得转动件233与第一基座231可转动地抵顶。当转动件233相对于第一基座231转动时,转动件233的第一凸轮2330转动地抵持转轴安装件251的第一抵顶凸轮2510使得转轴安装件251沿该转轴的轴向移动而挤压第一弹性件241,以使第一弹性件241弹性变形。此时,转动件233与转轴安装件251之间具有摩擦扭力且转动件233与第一基座231之间具有摩擦阻力,在不受外力的情况下,该摩擦扭力和该摩擦阻力能限位转动件233相对于第一基座231保持不动,从而使得支撑组件28保持弯折状态或展平状态不动,以实现支撑组件28的悬停,使得电子设备100具有悬停效果;其次,转轴装置22的悬停效果通过转动件233与转轴安装件251之间的摩擦扭力和转动件233与第一基座231之间的摩擦阻力共同实现的,因此,转轴装置22的悬停效果稳定;另外,第一弹性件241弹性抵推转轴安装件251抵顶转动件233以使转动件233抵顶第一基座231,使得转轴装置22的结构紧凑,转轴装置22的体积减小,从而减小转轴装置22占用折叠壳体20的内部空间,不仅有利于主板或电池等其他元件的布局,且有利于小型化发展;还有,转轴装置22的结构简单,制造成本较低,且各部件之间的连接可靠性高,整机强度提升。
如图4-图11所示,本实施例中,转动组件23包括两个第一基座231及两个连接件234,两个第一基座231沿转轴的轴向相互间隔,扭力组件25设于两个第一基座231之间,即两个第一基座231分别位于扭力组件25相对的两端,每一第一基座231相对的两侧分别设有一个转动件233,即两个转动件233分别可转动地连接于第一基座231相对的两侧;扭力组件25包括两个转轴安装件251,扭力组件25的转轴包括平行间隔的一对第一转轴253,两个转轴安装件251分别沿第一转轴253的轴向滑动地连接于一对第一转轴253相对两端,两个转轴安装件251相互背离的两侧分别沿第一转轴253的轴向滑动地连接于两个第一基座231。转轴安装件251对应第一基座231上的两个转动件233的第一凸轮2330设有两个第一抵顶凸轮2510。弹性组件24包括一对第一弹性件241及一对第二弹性件243,一对第一弹性件241弹性抵推其中一转轴安装件251使得该转轴安装件251的两个第一抵顶凸轮2510分别与对应的两个转动件233的第一凸轮2330转动地抵持,以使每一个转动件233与对应的第一基座231可转动地
抵顶;一对第二弹性件243弹性抵推另一转轴安装件251使得该转轴安装件251的两个第一抵顶凸轮2510分别与对应的两个转动件233的第一凸轮2330转动地抵地,以使每一个转动件233与对应的第一基座231可转动地抵顶;即设于每一第一基座231上的两个转动件233分别与对应的转轴安装件251可转动地抵顶。两个连接件234设于扭力组件25相对两侧,每一第一基座231上的两个转动件233远离该第一基座231的端部分别转动地连接于两个连接件234,连接件234连接于支撑组件28。支撑组件28包括连接于转动组件23正面中部的中部支撑件280及位于中部支撑件280相对两侧的两个侧部支撑件281,中部支撑件280连接于转动组件23,两个侧部支撑件281分别连接于转动组件23和扭力组件25,两个侧部支撑件281通过转动组件23及扭力组件25相对于中部支撑件280弯折或展平,从而实现支撑组件28的折叠或展平。当支撑组件28呈展平状态时,两个侧部支撑件281的正面及中部支撑件280的正面共面,柔性屏30的可折弯区31连接于中部支撑件280的正面和侧部支撑件281的正面;当两个侧部支撑件281呈折叠状态时,两个侧部支撑件281的正面和中部支撑件280的正面围成横截面呈水滴形或U形的空间,使得柔性屏30的可折弯区31弯曲成水滴形或U形;本实施例中,柔性屏30的可折弯区31弯曲成水滴形。当转动件233相对于第一基座231转动时,转动件233的第一凸轮2330转动地抵推对应的第一抵顶凸轮2510使得转轴安装件251沿第一转轴253的轴向移动以挤压第一弹性件241;此时,相对的第一凸轮2330与第一抵顶凸轮2510之间的摩擦扭力和转动件233与对应的第一基座231之间的摩擦阻力用以限位转动件233相对于第一基座231及转轴安装件251转动,在不受外力的情况下,转动件233相对于第一基座231及转轴安装件251保持不动,以实现转轴装置22的悬停,从而实现电子设备100的悬停。
本实施例中,由于转轴装置22的悬停效果通过两个第一基座231上的两个转动件233与对应的转轴安装件251之间的摩擦扭力,以及每一第一基座231上的两个转动件233与对应的第一基座231之间的摩擦阻力共同实现的,因此,转轴装置22的悬停效果稳定;另外,两个第一弹性件241弹性抵推其中一转轴安装件251抵顶对应的两个转动件233以使该两个转动件233抵顶对应的第一基座231,两个第二弹性件243弹性抵推另一转轴安装件251抵顶对应的两个转动件233以使该两个转动件233抵顶对应的第一基座231,从而使得转轴装置22的结构紧凑,转轴装置22的体积减小,从而减小转轴装置22占用折叠壳体20的内部空间,不仅有利于主板或电池等其他元件的布局,且有利于小型化发展;还有,由于转轴装置22的两个第一基座231的结构相同、四个转动件233的结构相同、两个转轴安装件251的结构也相同以及两个连接件234的结构相同,因此,各部件可以成批量生产制造,降低了制造成本,且转轴装置22的结构简单,各部件之间的连接可靠性高,整机强度提升。

上的两个转动件233分别对该第一基座231具有沿平行于第一转轴253的轴向方向的相同的抵顶力。

请一并参阅图1-图5,框体21包括正面211、背面213、相对的两侧面214及两端面215,转轴装置22连接于两个框体21相邻的两个端面215之间,柔性屏30的可折弯区31贴附于转轴装置22的正面,柔性屏30的非折弯区33连接于框体21的正面211。每一框体21朝向转轴装置22的端面215设有收容槽216,收容槽216穿通框体21的正面211,收容槽216相对的两端延伸至框体21相对的两侧面214。转轴装置22相对的两侧分别容置于两个框体21的收容槽216中,且每一连接件234与对应的框体21固定连接。框体21的背面213设有多个收容空间(图中未示),收容空间用于安装电路板、电池等电子器件。
将安装完成的转轴装置22置于两个框体21之间,将背盖29相对两侧的连接件234分别容置于两个框体21的收容槽216中,并将两个连接件234分别固定连接于两个框体21。此时,两个框体21的正面211及两个侧部支撑件281的正面共面。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,可折弯区31正对转轴装置22,两个非折弯区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,中部支撑件280的正面与两个侧部支撑件281的正面齐平,第二凸轮2540与第二抵顶凸轮2523相互抵顶地啮合,每一转轴安装件251的第一抵顶凸轮2510与对应的转动件234的第一凸轮2330相互抵顶,每一转轴安装件251与对应的第一基座231抵顶,以及每一第一扭力件252与第二基座255抵顶,以限定两个侧部支撑件281保持展平状态;且能使转轴装置22中各元件间的连接更紧凑,从而减小转轴装置22的整体体积,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;其次,由于侧部支撑件281的正面与中部支撑件280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。
请一并参阅图1-图4及图16-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的连接件234相对于第一基座231朝相互邻近的方向转动,带动两个转动件233相对于第一基座231转动而相互靠拢、两个第一扭力件252通过第一联动组件26同步折叠,以实现转轴装置22的两个侧部支撑件281相互折叠,柔性屏30的可折弯区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,该其中一框体21带动对应的转动件233相对于第一基座231向靠近柔性屏30的一侧转动,同时,连接件234带动两个第一扭力件252同步相互折叠,两个第一扭力件252的第二抵顶凸轮2523分别抵推第一抵持件254的两个第二凸轮2540,以带动第一抵持件254挤压第一弹性件241;同时,每一第一基座231的两个转动件233相对于第一基座231同步
转动而相互靠拢,以带动两个侧部支撑件281同步相互靠拢,两个转轴安装件251分别挤压第一弹性件241及第二弹性件243,直至两个侧部支撑件281的正面与中部支撑件280的正面围成横截面成水滴状;柔性屏30的可折弯区31随转轴装置22弯折,直至柔性屏30的两个非折弯区33的正面相互贴合,可折弯区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,每一第一转轴253上的第一扭力件252的第二抵顶凸轮2523与第二凸轮2540之间的摩擦扭力和转轴安装件251的第一抵顶凸轮2510与对应的第一凸轮2330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281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的可折弯区31弯折围成水滴形,减少弯折后的可折弯区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分别带动转动件233相对于第一基座231转动向靠近柔性屏30的一侧转动,带动两个第一扭力件252围绕对应的第一转轴253转动向靠近柔性屏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。

本发明的电子设备100的转轴装置22通过转动组件23及扭力组件25实现同步折叠或展开,由于第一扭力件252与第一抵持件254之间具有摩擦扭力及转动件233与转轴安装件251之间具有摩擦扭力,在电子设备100不受外力的情况下实,这些摩擦阻力能限位第一扭力件252及转动件233相对于第一基座231保持不动,以实现两个侧部支撑件281的悬停,使得电子设备100具有悬停效果;其次,转动件233与第一基座231之间具有摩擦阻力及第一扭力件252与第二基座255之间具有摩擦阻力,以使得电子设备100的悬停效果更好;另外,第一弹性件241相对的两端分别弹性抵顶第一抵持件254和转轴安装件251,第二弹性件243相对的两端分别弹性抵顶第二基座255和对应的转轴安装件251,使得转轴
装置22的结构紧凑,转轴装置22的体积减小,从而减小转轴装置22占用折叠壳体20的内部空间,不仅有利于主板或电池等其他元件的布局,且有利于小型化发展;转轴装置22的结构简单,制造成本较低,且各部件之间的连接可靠性高,整机强度提升。

当转轴装置22a由完全弯折状态进行展开时,将其中一连接件234相对于第一基座231朝远离另一连接件234展开,该其中一连接件234带动转动件233的第一圆弧轨2332在第一基座231的第一圆弧槽2312中转动,并带动对应的第一扭力件252及第二扭力件256分别围绕对应的第一转轴253转动,以使两个第一扭力件252相互远离及两个第二扭力件256相互远离,第一扭力件252抵推第一抵持件254沿第二转轴250的轴向移动而挤压第一弹性件241,第二扭力件256抵推第二抵持件257沿第二转轴250的轴向移动而挤压第二弹性件243;第一扭力件252上的第一齿轮261绕第二转轴250转动以带动第一从动齿轮组263的两个第一从动齿轮2630转动,通过第一从动齿轮组263带动另一第一扭力件252上的第一齿轮261绕对应的第二转轴250,从而实现两个第一扭力件252的同步展开,第二扭力件256上的第二齿轮261a绕第二转轴250转动以带动第二从动齿轮组263a的两个第二从动齿轮2730转动,通过第二从动齿轮组263a带动另一第二扭力件256上的第二齿轮261a绕对应的第二转轴250,从而实现两个第二扭力件256的同步展开;转动组件23的两个转动件233相对于第一基座231同步转动而相互展开,以带动支撑组件28相互展开,直至支撑组件28的正面呈展平状。
在转轴装置22a折叠过程或展开过程中,其中一第二转轴250上的第二凸轮2540与第二抵顶凸轮2523之间的轴向力等于两个第一弹性件241的弹力之和,与第一弹性件241抵顶的转轴安装件251的第一抵顶凸轮2510与对应的第一凸轮2330之间的轴向力等于两个第一弹性件241的弹力之和;另一第二转轴250上的第三凸轮2570与第三抵顶凸轮2563之间的轴向力等于两个第二弹性件243的弹力之和,与第二弹性件243抵顶的转轴安装件251的第一抵顶凸轮2510与对应的第一凸轮2330之间的轴向力等于两个第二弹性件243的弹力之和。第二抵顶凸轮2523与第二凸轮2540之间的摩擦扭力、第三抵顶凸轮2563与第三凸轮2570之间的摩擦扭力、每一转轴安装件251的第一凸轮2330与对应的第一抵顶凸轮2510之间的摩擦扭力、每一转轴安装件251与对应的第一基座231之间的摩擦阻力、每一第一扭力件252背离第二抵顶凸轮2523的一端与第三基座258之间的摩擦阻力,以及每一第二扭力件256背离第三抵顶凸轮2563的一端与对应的转轴安装件251之间的摩擦阻力使两个侧部支撑件限位在70度至130度之间的特定角度。

将转轴装置22b由展平状态进行弯折时,将其中一连接件234相对于第一基座231向另一连接件234弯折,该其中一连接件234带动转动件233相对于第一基座231转动,并带动对应的第一扭力件252及第三扭力件259分别围绕对应的第二转轴250转动,以使两个第一扭力件252相互靠拢及两个第三扭力件259相互靠拢,第一扭力件252抵推第一抵持件254沿第二转轴250的轴向移动而挤压第一弹性件241,第二扭力件259同步抵推两个第二抵持件257沿第二转轴250的轴向移动而分别挤压第一弹性件241及第二弹性件243;第一扭力件252上的第一齿轮261绕第二转轴250转动以带动第一从动齿轮组263的两个第一从动齿轮2630转动,通过第一从动齿轮组263带动另一第一扭力件252上的第一齿轮261绕对应的第二转轴250,从而实现两个第一扭力件252的同步折叠;第三扭力件259上的第三齿轮261b绕第二转轴250转动以带动第三从动齿轮组263b的两个第三从动齿轮转动,通过第三从动齿轮组263b带动另一第三扭力件259上的第三齿轮261b绕对应的第二转轴250,从而实现两个第三扭力件259的同步折叠;同时,两个第一基座231上的转动件233分别同步转动而相互靠拢,以带动两个侧部支撑件同步相互靠拢,直至支撑组件28的正面围成横截面成水滴状。
当转轴装置22b由完全弯折状态进行展开时,将其中一连接件234相对于第一基座231朝远离另一连接件234展开,该其中一连接件234带动转动件233相对于第一基座231转动,并带动对应的第一扭
力件252及第三扭力件259分别围绕对应的第一转轴253转动,以使两个第一扭力件252相互远离及两个第三扭力件259相互远离,第一扭力件252抵推第一抵持件254沿第二转轴250的轴向移动而挤压第一弹性件241,第三扭力件259同步抵推一对第二抵持件257分别沿第二转轴250的轴向移动而分别挤压第一弹性件241及第二弹性件243;第一扭力件252上的第一齿轮261绕第二转轴250转动以带动第一从动齿轮组263的两个第一从动齿轮转动,通过第一从动齿轮组263带动另一第一扭力件252上的第一齿轮261绕对应的第二转轴250,从而实现两个第一扭力件252的同步展开,第三扭力件259上的第三齿轮261b绕第二转轴250转动以带动第三从动齿轮组263b的两个第三从动齿轮转动,通过第三从动齿轮组263b带动另一第三扭力件259上的第三齿轮261b绕对应的第二转轴250,从而实现两个第三扭力件259的同步展开;转动组件23的两个转动件233相对于第一基座231同步转动而相互展开,以带动支撑组件相互展开,直至支撑组件的正面呈展平状。
在转轴装置22b折叠过程或展开过程中,第二抵顶凸轮2523与第二凸轮2540之间的摩擦扭力、每一第三扭力件259相对两端的第四抵顶凸轮2593分别与第三凸轮2570之间的摩擦扭力、每一转轴安装件251的第一凸轮2330与对应的第一抵顶凸轮2510之间的摩擦扭力、每一第一扭力件252背离第二抵顶凸轮2523的一端与转轴安装件251之间的摩擦阻力,以及每一转动件233与对应的第一基座231之间的摩擦阻力使两个侧部支撑件限位在70度至130度之间的特定角度。
本发明还提供设有上述转轴装置22b的折叠壳体,转轴装置22b位于两个壳体之间,转轴装置22b相对的两侧分别连接于折叠壳体的两个壳体。
本发明还提供设有上述转轴装置22b的电子设备,该电子设备包括转轴装置22b、柔性屏及两个壳体,该转轴装置22b位于两个壳体之间,转轴装置22b相对的两侧分别连接于两个该壳体,该柔性屏的背面贴合于转轴装置22b的正面和两个壳体的正面。
本发明转轴装置22b通过转动组件及扭力组件实现同步折叠或展开,由于第一扭力件252与第一抵持件254之间具有摩擦阻力、一对第三扭力件259与两个第二抵持件257之间具有摩擦阻力,以及转动件233与转轴安装件251之间具有摩擦阻力,在电子设备不受外力的情况下,这些摩擦阻力能限位第一扭力件252、第三扭力件259及连接件233相对于第一基座231保持不动,以实现两个侧部支撑件的悬停,使得电子设备具有悬停效果;其次,转动件233与第一基座231之间具有摩擦阻力及第一扭力252与转轴安装件251之间具有摩擦阻力,以使得电子设备的悬停效果更好;另外,第一弹性件241相对的两端分别弹性抵顶第一抵持件254和其中一第二抵持件257,第二弹性件243相对的两端分别弹性抵顶另一第二抵持件257和对应的转轴安装件251,使得转轴装置22b的结构紧凑,转轴装置22b的体积减小,从而减小转轴装置22b占用折叠壳体的内部空间,不仅有利于主板或电池等其他元件的布局,且有利于小型化发展;转轴装置22b的结构简单,制造成本较低,且各部件之间的连接可靠性高,整机强度提升。
