如图4至图7所示,限位机构27还包括止挡件274及第二弹性件275,止挡件274套设于转轴261,第二弹性件275以压缩状态设于第一抵持件272与止挡件274之间,且可以设于两个第一弹性件273之 间;第二弹性件275提供第一抵持件272与第一抵推件270之间相互抵顶的弹力,以及第二抵持件276与第二抵推件271之间相互抵顶的弹力。也就是,第一弹性件273及第二弹性件275一并提供第一抵持件272与第一抵推件270之间相互抵顶的弹力及第二抵持件276与第二抵推件271之间相互抵顶的弹力。第一弹性件273与第二弹性件275的结构可以相同或不同。本实施例中,第一弹性件273和第二弹性件275均为弹簧。

如图6及图7所示,限位机构27还包括定位件278,定位件278设于转轴261远离第二抵持件276一端。转轴261远离第二抵持件276的端部卡接于定位件278。本实施例中,定位件278为大致矩形的定位片,所述定位片的一侧相对的两端分别设有卡扣部2782。本实施例中,卡扣部2782为C形卡扣。在其他实施例中,卡扣部2782可以是但不限于U形卡扣等。优选地,定位件278相对的两端面设为圆弧面,以更方便转轴装置22的折叠或展开。
请一并参阅图3至图12,组装转轴装置22时,将两个转轴261设有卡槽2613的一端分别插入第二抵持件276相对两端的轴孔2763,直至转轴261的止挡部2612挡止于第二抵持件276的侧面。将两个联动件263放置于定位座25相对的两侧,使定位座25的两个凸耳2531分别插入两个联动件263的定位槽2633,定位部251位于远离第一齿轮2630的一侧,且每一凸耳2531的轴孔2533的轴心线与对应的联动件263的第一套筒的轴心线共线。然后将两个转轴261设有卡槽2663的一端分别插入两个联动件263的第一套筒,直至第二抵持件276的两个第二抵顶凸轮2761分别抵持两个联动件263的第二凸轮2711。接着将两个第二齿轮2650的连接轴2652远离止挡部2655的一端分别插入定位座25的第二转接孔2535中,使两个第二齿轮2650彼此啮合。再将第一抵持件272套设于两个转轴261上,直至两个第二齿轮2650的连接轴2652靠近止挡部2655的一端插入第二齿轮2650的第一转接孔2725中,使第一抵持件272的两个第一抵顶凸轮2721分别抵持两个联动件263的第一凸轮2701。第二齿轮2650的连接轴2652插入第一抵持件272对应的第一转接孔2725中,直至第二齿轮2650的止挡部2655止挡于第一抵持件272的侧面。再将两个第一弹性件273分别套设于两个转轴261,直至第一弹性件273的一端抵顶第一抵持件272。将第二弹性件275套设于止挡件274的定位部2744。再将止挡件274套设于两个转轴261,即两个转轴261远离第二抵持件276的端部分别插入止挡件274相对的两个导滑孔2745。再将定位件278的两个卡扣部2782分别卡接于两个转轴261的卡槽2613。
此时,两个第一弹性件273及第二弹性件275被止挡件274与第一抵持件272弹性夹持,即第一弹性件273和第二弹性件275均对第一抵持件272具有预弹力,使得第一凸轮2701的凹凸面与对应的第一抵顶凸轮2721的凹凸面之间紧密贴合,以及第二凸轮2711的凹凸面与第二抵顶凸轮2761的凹凸面之间紧密贴合;第一凸轮2701相对于第一抵顶凸轮2721的转动使第二凸出部2726与第一凹陷部2704彼此吻合或脱离,且第二凹陷部2727与第一凸出部2702彼此吻合或脱离;第二凸轮2711相对于第二 抵顶凸轮2761转动使第四凸出部2766与第三凹陷部2714彼此吻合或脱离,且第四凹陷部2767与第三凸出部2712彼此吻合或脱离。需要说明的是转动部2632相对于定位座25转动以带动转动部2632相对两端的第一凸轮2701及第二凸轮2711分别相对于第一抵顶凸轮2721和第二抵顶凸轮2761转动,能同步使第二凸出部2726与第一凹陷部2704彼此吻合或脱离、第二凹陷部2727与第一凸出部2702彼此吻合或脱离、第四凸出部2766与第三凹陷部2714彼此吻合或脱离,以及第四凹陷部2767与第三凸出部2712彼此吻合或脱离。
若第一弹性件273和第二弹性件275均具有预弹力F0,每一转轴261上的第一凸轮2701与对应的第一抵顶凸轮2721及第二凸轮2711与对应的第二抵顶凸轮2761的轴向力F等于二分之三预弹力F0,即F=3/2F0。若第一弹性件273与第二弹性件275为不同的弹性件,第一弹性件273具有预弹力F1,第二弹性件275具有预弹力F2,则每一转轴261上的第一凸轮2701与对应的第一抵顶凸轮2721及第二凸轮2711与对应的第二抵顶凸轮2761的轴向力F等于第一弹性件273的预弹力F1加上二分之一的预弹力F2,即F=F1+1/2F2。两个第二齿轮2650的连接轴2652的轴心线平行于一对转轴261的轴心线,进一步地,连接轴2652的轴心线构成的平面可以与一对转轴261的轴心线构成的平面共面或平行。本实施例中,连接轴2652的轴心线构成的平面与一对转轴261的轴心线构成的平面共面,也就是一对转轴261及一连接轴2652平排设置,两个第一弹性件273和一个第二弹性件275平排设置。在一对转轴261之间的宽度相同的情况下,第一弹性件273及第二弹性件275均为弹簧,因此三根弹簧可以选用线径更大、外径更大的弹簧,从而提供更大的弹力;在此基础上,仅需第一抵持件272的第一抵顶凸轮2721与联动件263的第一凸轮2701之间及第二抵持件276的第二抵顶凸轮2761与联动件263的第二凸轮2711之间的摩擦扭力即可提供需要扭矩目标,就能够使联动件263相对于定位座25定位,无需在第二齿轮2650与第一抵持件272及第二抵持件276之间加工凸轮面,使零件加工成本低。
在其他实施例中,连接轴2652的轴心线可以位于一对转轴261的轴心线的上侧或下侧,所述上侧指相较于转轴261的轴心线靠近柔性件30的出光面的一侧,所述下侧指相较于转轴261的轴心线远离柔性件30的出光面的一侧。当一对连接轴2652的轴心线构成的平面与一对转轴261的轴心线构成的平面平行时,能使连接轴2652与转轴261的相对位置更紧凑,从而使联动机构26的各部件及限位机构27的各部件布局更紧凑,从而减少转轴装置22的整体宽度,使得转轴装置22占用折叠壳体20的内部空间更小,为主板或电池等其他电子器件提供空间,从而能提升电子设备100的性能。当其中一联动件263绕对应的转轴261相对于定位座25转动时,该联动件263相对两端的第一凸轮2701及第二凸轮2711分别同步相对于第一抵持件272的第一抵顶凸轮2721及第二抵持件276的第二抵顶凸轮2761转动;同时,该联动件263的第一齿轮2630的转动带动对应的第二齿轮2650绕对应的连接轴2652转动,该第二齿轮2650带动另一第二齿轮2650绕对应的连接轴2652转动,所述另一第二齿轮2650带动另一联动件263绕对应的连接轴2652转动,从而使两个联动件263的连杆2635同步靠拢或同步展开。由于定位座25限制联动件263在转轴261的轴向上移动,因此,第一抵持件272被第一凸轮2701抵推沿转轴261的轴向远离联动件263滑动,第一弹性件273和第二弹性件275被压缩而弹性变形,同时,第二抵持件276被第二凸轮2711抵推沿转轴261的轴向远离联动件263滑动,第二抵持件276带动转轴261、止挡件274及定位件278一并滑动,止挡件274的滑动进一步挤压第一弹性件273和第二弹性件275发生弹性变形。具体地,如第一抵持件272沿转轴261的轴向滑动挤压第一弹性件273和第二弹性件275的压缩量为δ,第二抵持件276的滑动带动止挡件274沿轴向滑动挤压第一弹性件273和第二弹性件275的压缩量也为δ,则一对联动件263在相对弯折或展平的过程中,第一弹性件273和第二弹性件275的最 大压缩量为2δ。第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力和第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力使两个联动件263相互定位。
组装转轴装置22时,将联动机构26及限位机构27连接于转动组件24,具体地,将两个转轴261的连接部2615分别连接于安装座241;将支撑机构23放置于转动组件24、联动机构26及限位机构27的正面,使支撑机构23的中部支撑件231连接于安装座241,以及两个转动机构243远离安装座241的一端分别连接于两个侧部支撑件233。转轴装置22还包括背盖28,安装座241及定位座25连接于背盖28。具体地,背盖28为条形框,背盖28具有收容槽280,安装座241及定位座25容置于收容槽280中并固定连接于背盖28。优选地,背盖28于收容槽280的内表面上设有第一安装部(图中未示)及第二安装部(图中未示),安装座241连接于第一安装部,定位座25连接于第二安装部。安装座241与第一安装部之间的连接以及定位座25与第二安装部之间的连接可以通过但不限于螺接、卡接或胶接等方式。本实施例中,锁固件(图中未示)穿过定位座25的定位孔2512锁固于背盖28,以使定位座25固定于背盖28。
当转动机构243相对于安装座241转动以带动联动件263绕对应的转轴261相对于定位座25转动时,联动件263转动以带动齿轮组265同步转动及带动侧部支撑件233相对于安装座241转动,以使侧部支撑件233与中部支撑件231同步相互折弯或同步相互展开。在侧部支撑件233的折弯或展开过程中,第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力和第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力使两个侧部支撑件233能相互定位。
请一并参阅图2至图5及图10至图16,将转轴装置22由展平状态进行弯折时,将其中一转动机构243相对于安装座241向另一转动机构243弯折,所述其中一转动机构243带动联动件263绕对应的转轴261相对于定位座25转动。联动件263的转动带动对应的第一齿轮2630转动,通过齿轮组265带动对应的两个第一齿轮2630同步转动,同步转动的第一齿轮2630带动对应的两个联动件263同步相互靠拢;同时,两个侧部支撑件233通过转动机构243及联动机构26的带动实现同步相互靠拢,直至两个侧部支撑件233与中部支撑件231围成横截面成水滴状。
上述过程中,每一转轴261上的第一凸轮2701与对应的第一抵顶凸轮2721之间的轴向力等于两个第一弹性件273和第二弹性件275的弹力之和的二分之一;同时,每一转轴261上的第二凸轮2711与第二抵顶凸轮2761之间的轴向力等于两个第一弹性件273和第二弹性件275的弹力之和的二分之一;第一凸轮2701与第一抵顶凸轮2721及第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力以使两个侧部支撑件233限位在70度至130度之间的特定角度。
在另一使用方式中,可以将两个转动机构243朝相向方向一同转动,每一转动机构243相对于安装座241向另一转动机构243转动,以带动联动机构26的两个联动件263绕对应的转轴261朝相向方向一同转动。两个联动件263的同步转动带动两个第一齿轮2630同步转动,两个第一齿轮2630的同步转动带动两个第二齿轮2650同步转动,并带动对应的两个联动件263的连杆2635同步相互靠拢;同时,两个侧部支撑件233通过转动机构243及联动机构26的带动实现同步相互靠拢,直至两个侧部支撑件233与中部支撑件231围成横截面成水滴状。
当将转轴装置22由完全弯折状态进行展开时,将其中一转动机构243相对于安装座241朝远离另一转动机构243展开,所述其中一转动机构243带动联动件263绕对应的转轴261相对于定位座25转动。联动件263的转动带动对应的第一齿轮2630转动,通过齿轮组265带动对应的两个第一齿轮2630同步转动,同步转动的第一齿轮2630带动对应的两个联动件263同步相互远离;同时,两个侧部支撑 件233通过转动机构243及联动机构26的带动实现同步相互展开,直至两个侧部支撑件233与中部支撑件231呈展平状。
上述过程中,每一转轴261上的第一凸轮2701与对应的第一抵顶凸轮2721之间的轴向力等于两个第一弹性件273和第二弹性件275的弹力之和的二分之一;同时,每一转轴261上的第二凸轮2711与对应的第二抵顶凸轮2761之间的轴向力等于两个第一弹性件273和第二弹性件275的弹力之和的二分之一;第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力及第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力能使两个侧部支撑件233限位在70度至130度之间的特定角度。
在另一使用方式中,可以将两个转动机构243朝相互远离的方向一同转动,每一转动机构243相对于安装座241远离另一转动机构243转动,以带动联动机构26的两个联动件263绕对应的转轴261朝相反方向一同转动。两个联动件263的同步转动带动两个第一齿轮2630同步转动,两个第一齿轮2630的同步转动带动两个第二齿轮2650同步转动,并带动对应的两个联动件263同步相互远离;同时,两个侧部支撑件233通过转动机构243及联动机构26的带动实现同步相互远离,直至两个侧部支撑件233与中部支撑件231齐平。
在一些实施例中,转轴装置22的第一抵持件272和第二抵持件276两者之一可以省略,从而能减少元件,不仅能使转轴装置22的整体体积进一步减少,以减小占用折叠壳体20的内部空间,以方便其他元件的布局;且能使转轴装置22的制造成本更低。具体地,若省略第二抵持件276,则联动件263的转动部2632的第二抵推件271省略;若省略第一抵持件272,则联动件263的转动部2632的第一抵推件270省略。
在一些实施例中,转轴装置22的两个联动件263的两者之一上的第一凸轮2701及第二凸轮2711可以省略,从而减小凸轮面的制造,使得转轴装置22的制造成本更低。具体地,若其中一联动件263的转动部2632相对两端的第一凸轮2701及第二凸轮2711省略,则第一抵持件272对应第一凸轮2701的第一抵顶凸轮2721及第二抵持件276对应第二凸轮2711的第二抵顶凸轮2761省略。
在一些实施例中,其中一联动件263面朝第一抵持件272一端的第一凸轮2701省略,另一联动件263面朝第二抵持件276一端的第二凸轮2711省略,则第一抵持件272对应所述其中一联动件263的第一抵顶凸轮2721省略,第二抵持件276对应另一联动件263的第二抵顶凸轮2761省略。由此,可以减小凸轮面的制造,使得转轴装置22的制造成本更低。
请一并参阅图1至图3,将安装完成的转轴装置22置于两个框体21之间,将背盖28相对两侧的转动机构243分别容置于两个框体21的收容槽216中,并将两个转动机构243远离安装座241的端部分别固定连接于两个框体21。此时,在展开状态下两个框体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及支撑机构23的正面,可折弯区域31正对支撑机构23,两个非折弯区域33分别正对两个框体21的正面。
转轴装置22的定位座25能定位于折叠壳体20的一侧、相对的另一侧或中部。具体地,定位座25连接于背盖28的收容槽280的内表面的一端、定位座25连接于背盖28的收容槽280的内表面的相对的另一端,或者定位座25连接于背盖28的收容槽280的中部;也就是,可以根据电子设备100的各元件排布的需要,将联动机构26和限位机构27的整体结构定位于折叠壳体20的一侧、相对的另一侧或中部位置等,以方便其他元件的布局,并尽量减少联动机构26和限位机构27占用折叠壳体20的内部空间。
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,第一凸轮2701与第一 抵顶凸轮2721相互贴合,且第二凸轮2711与第二抵顶凸轮2761相互贴合,以使支撑机构23保持展平状态;由于支撑机构23的正面为完整面,因此,柔性件30在展平时不会受到段差处的冲击,柔性件30不会出现彩点、亮点等不良问题,保证柔性件30的可靠性,同时,也提升柔性件30的触摸手感,提高用户使用体验;另外,转轴装置22中各元件间的连接紧凑,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。
请一并参阅图1及图17至图20,当需要弯折电子设备100时,对电子设备100的两个框体21至少其中一个施加折弯的力,使连接于两个框体21的转动机构243朝相互邻近的方向转动,通过联动机构26实现转轴装置22的折弯,柔性件30的可折弯区域31随支撑机构23弯折。具体地,如对其中一框体21施加折弯的力,该框体21带动对应的转动机构243相对于安装座241向靠近柔性件30的一侧转动,转动机构243带动联动件263绕对应的转轴261相对于定位座25转动,联动件263的转动带动对应的第一齿轮2630转动,通过齿轮组265带动对应的两个第一齿轮2630同步转动,同步转动的第一齿轮2630带动对应的两个联动件263同步相互靠拢。同时,限位机构27相对两侧的转动机构243相对于安装座241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呈折弯状态;柔性件30的可折弯区域31随转轴装置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。
在上述过程中,第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力和/或第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力大于柔性件30的反弹力,能使两个框体21限位在130度至70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243向靠近柔性件30的一侧转动,并通过转轴装置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243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,该框体21带动对应的转动机构243相对于安装座241向远离柔性件30的一侧转动,以带动对应的联动件263绕转轴261转动;同时,联动件263的转动带动对应的第一齿轮2630转动,通过齿轮组265带动对应的两个第一齿轮2630同步转动,同步转动的第一齿轮2630带动对应的两个联动件263同步相互远离;同时,两个转动机构243相对于安装座241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,柔性件30的可折弯区域31随转轴装置22展开,直至柔性件30展平。
在上述过程中,第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力和/或第二凸轮2711与第二抵顶凸轮2761之间的摩擦扭力大于柔性件30的反弹力,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243相对于向远离柔性件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通过转动组件24、联动机构26及限位机构27实现同步折弯或展开,且能使两个框体21限位在130度至70度之间的特定角度。由于联动机构26及限位机构27的各元件连接紧凑,从而减小转轴装置22的整体宽度,降低转轴装置22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的第一弹性件273及第二弹性件275能提供 较大的轴向力,使得第一凸轮2701与第一抵顶凸轮2721之间具有较大的摩擦扭力,且第二凸轮2711与第二抵顶凸轮2761之间也具有较大的摩擦扭力;因此,由第一凸轮2701与第一抵顶凸轮2721之间的摩擦扭力和第二凸轮2711与第二抵顶凸轮2761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-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的联动机构26及限位机构27的各元件之间通过套接或卡接的方式连接,容易组装或拆卸,方便维修,方便更换转轴装置22的元件,能够避免转轴装置22中的某一个或几个元件失效而导致整个转轴装置22报废的情况。
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。
