技术领域
本申请实施例涉及电子设备技术领域,特别涉及一种转轴机构及可折叠设备。
背景技术
随着屏幕技术的发展,柔性屏越来越多的应用到了电子设备中。设置有柔性屏的可折叠设备(如折叠手机、折叠平板、折叠电脑等电子设备)在折叠和展开时,均需要保持良好的外观形态,以及满足较高的可靠性和较好的操作体验。
一些可折叠设备包括柔性屏、两个壳体以及转轴机构,转轴机构可折叠和展开,两个壳体分别紧固连接在转动机构的两侧,且用于安装和支撑柔性屏,两个壳体及其上安装的柔性屏可随转轴机构一起折叠和展开。可折叠设备在使用的过程中,柔性屏需随可折叠设备进行长期多次的折叠,这会导致柔性屏的寿命较短。
因此如何设计一种转轴机构以尽量保证柔性屏在折叠过程中不被拉扯是当前亟待解决的问题。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释,而非旨在限定本申请,下面将结合附图对本申请实施例的实施方式进行详细描述。
图1为本申请实施例提供的一种可折叠设备展开时的示意图,图2为本申请实施例提供的一种可折叠设备折叠时的示意图。
参看图1、图2所示,本申请实施例提供一种可折叠设备,可以通过折叠和展开来改变自身的形态,以满足用户在不同场景下的需求。例如,在携带时,可进行折叠,以减小可折叠设备的尺寸;在使用时,可展开,以增大用于显示或者操作的屏幕的尺寸。
可以理解的是,本申请实施例提供的可折叠设备可以包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer,UMPC)、手持计算机、触控电视、对讲机、上网本、POS机、个人数字助理(personal digital assistant,PDA)、可穿戴设备、虚拟现实设备等可折叠的固定终端或移动终端。本申请实施例以可折叠的手机为例进行说明。
参看图1所示,本申请实施例的可折叠设备,可以包括柔性屏100、壳体组件200以及转轴机构300。壳体组件200包括位于转轴机构300两侧的第一壳体210和第二壳体220,第一壳体210和第二壳体220分别与转轴机构300相对的两侧紧固连接。需要说明的是,第一壳体210和第二壳体220可以通过焊接、粘接或者螺栓等紧固件连接的方式分别与转轴机构300的两侧紧固连接。转轴机构300相对的两侧可设置连接部,第一壳体210和第二壳体220可分别通过转轴机构300两侧的连接部与转轴机构300紧固连接。在实际应用中,第一壳体210和第二壳体220内可以安装处理器、电池、摄像头等器件。
继续参见图1,本申请实施例中,柔性屏100的两端分别安装在第一壳体210和 第二壳体220上。需要说明的是,柔性屏100设置在第一壳体210、第二壳体220以及转轴机构300的同一侧的表面,转轴机构300可用于支撑柔性屏100,柔性屏100可以包括依次连接的第一屏幕区域110、第二屏幕区域120和第三屏幕区域130,第一屏幕区域110固定在第一壳体210上、第三屏幕区域130固定在第二壳体220上,第一屏幕区域110和第三屏幕区域130可通过粘接等方式进行固定,转轴机构300用于支撑第二屏幕区域120。柔性屏100可以用于图像显示,也可以作为虚拟键盘用于输入信息。
示例性的,柔性屏100可以为有机发光二极管显示屏、有源矩阵有机发光二极体或者主动矩阵有机发光二极体显示屏、迷你发光二极管显示屏、微型发光二极管显示屏、微型有机发光二极管显示屏、量子点发光二极管显示屏等。
参见图1、图2,本申请实施例中,转轴机构300可以在展开状态和折叠状态之间切换。转轴机构300处于展开状态时,可使第一壳体210、第二壳体220及柔性屏100展开,此时,第一壳体210和第二壳体220之间可以大致呈180°(允许存在少许偏差,例如165°、177°或者185°),柔性屏100的第二屏幕区域120可展开,第一屏幕区域110和第三屏幕区域130可处于同一平面内(允许存在少许偏差);转轴机构300处于折叠状态时,可使第一壳体210和第二壳体220及柔性屏100折叠,此时,第一壳体210和第二壳体220能够完全合拢至相互平行(允许存在少许偏差),柔性屏100的第二屏幕区域120发生弯折变形,第一屏幕区域110和第三屏幕区域130也可合拢至相互平行(允许存在少许偏差)。当然,转轴机构300还具有在展开状态和折叠状态之间切换过程中的中间状态。可折叠设备可以通过转轴机构300的展开状态和折叠状态的切换,使第一壳体210、第二壳体220以及柔性屏100随之运动,以实现可折叠设备的折叠和展开。
需要说明的是,可折叠设备可以包括一个转轴机构300以及分别在转轴机构300相对的两侧紧固连接的一个第一壳体210和一个第二壳体220,第一壳体210和第二壳体220可以相向转动至层叠以及背向转动至同一平面(允许存在少许偏差),此时,可折叠设备可以折叠成两层。
可折叠设备也可以包括两个或者更多个并列设置的第一壳体210,每两个相邻的第一壳体210之间设置一个第二壳体220,每个第一壳体210与其相邻的第二壳体220之间通过一个转轴机构300连接,此时,可折叠设备可以折叠为三层或者更多层。例如,可折叠设备包括两个第一壳体210和一个第二壳体220,第二壳体220设于两个第一壳体210之间,第二壳体220的两侧分别通过一个转轴机构300与一个第一壳体210转动连接,两个第一个壳体均可相对于第二壳体220相向转动至叠层,两个第一个壳体也可相对于第二壳体220背向转动至与第二壳体220共面(允许存在少许偏差),此时,可折叠设备可以折叠成三层。
图3是为本申请实施例提供的又一种可折叠设备展开时的示意图。
参看图3所示,转轴机构300包括主轴组件310和折叠组件320,折叠组件320与主轴组件310连接,折叠组件320可以相对主轴组件310旋转以使转轴机构300在展开状态与折叠状态之间切换,折叠组件320相对的两侧分别用于与转轴机构300两侧的第一壳体210和第二壳体220紧固连接。可以理解的是,用于与第一壳体210和 第二壳体220紧固连接的连接部设于折叠组件320上。折叠组件320位于主轴组件310两侧的部分可相对于主轴组件310转动,以使折叠组件320可以折叠和展开,实现转轴机构300在折叠状态和展开状态的切换。
为避免柔性屏100产生拉伸或者收缩,可使转轴机构300的折叠组件320在旋转的过程中进行伸缩,使转轴机构300在不同状态时,折叠组件320的长度不同。具体来说,可折叠设备在折叠的过程中,转轴机构300的折叠组件320不断伸长,使与折叠组件320两侧紧固连接的第一壳体210和第二壳体220不断远离主轴组件310,从而可减小柔性屏100被压缩的风险,可折叠设备在展开的过程中,转轴机构300的折叠组件320不断缩短,使与折叠组件320两侧紧固连接的第一壳体210和第二壳体220不断靠近主轴组件310,从而可减小柔性屏100被拉伸的风险。
图4为相关技术中的一种可折叠设备折叠时的示意图。
参看图4所示,相关技术中的转轴机构300a,可通过分别位于主轴组件310a两侧的两块活动支撑板331a来对柔性屏100进行支撑,两块活动支撑板331a活动安装在折叠组件320a上。例如,可使活动支撑板331a的一端与折叠组件320a远离主轴组件310a的一端转动连接,另一端与折叠组件320a靠近主轴组件310a的一端或者与主轴组件310a滑动连接,且活动支撑板331a可相对于折叠组件320a靠近主轴组件310a的一端或者主轴组件310a转动,依靠折叠组件320a在展开和折叠的过程中的转动以及伸缩,来改变活动支撑板331a与折叠组件320a的相对位置和夹角,以使转轴机构300a折叠之后,主轴组件310a两侧的活动支撑板331a以及主轴组件310a之间可以形成一端膨大的容屏空间。
然而,活动支撑板331a与折叠组件320a活动安装时,供活动支撑板331a与折叠组件320a相对活动的间隙会造成活动支撑板331a的位置不稳定,两块活动支撑板331a之间的夹角会产生公差,且转轴机构300a在折叠状态和展开状态之间切换时,折叠组件320a的伸缩需要由折叠组件320a的转动来进行控制,活动安装在折叠组件320a上的活动支撑板331a的运动需要由折叠组件320a的伸缩和转动共同来控制。换句话来说,要想控制活动支撑板331a的运动,需要先通过折叠组件320a的转动来控制折叠组件320a的伸缩,再通过折叠组件320a的伸缩以及折叠组件320a的转动来控制活动支撑板331a运动。这样,控制活动安装在折叠组件320a上的活动支撑板331a的控制链长,活动支撑板331a在运动过程中的位置控制较为困难,两块活动支撑板331a之间的夹角不稳定,公差较大,造成容屏空间的形态不稳定,会增大柔性屏损坏的风险。
图5为本申请实施例提供的一种转轴机构在展开状态时的示意图,图6为本申请实施例提供的一种转轴机构在折叠状态时的示意图,图7为本申请实施例提供的一种转轴机构在折叠状态时使柔性屏折叠的示意图。
如图5-图7所示,并参看图3,为解决上述问题,本申请实施例提供一种转轴机构300,包括主轴组件310、折叠组件320和支撑组件330,折叠组件320可以相对主轴组件310旋转以使转轴机构300在展开状态与折叠状态之间切换。折叠组件320包括导杆臂组、支撑臂组和连接架组。导杆臂组包括第一导杆臂325和第二导杆臂326,支撑臂组包括第一支撑臂323和第二支撑臂324,连接架组包括第一连接架321 和第二连接架322,第一导杆臂325、第一支撑臂323和第一连接架321分布于主轴组件310的一侧,第二导杆臂326、第二支撑臂324和第二连接架322分布于主轴组件310的另一侧。第一支撑臂323的一端与主轴组件310转动连接,第一支撑臂323的另一端与第一连接架321通过二者上设置的第一弧形滑槽341以及与第一弧形滑槽341滑动配合的第一弧形臂343转动连接。第一导杆臂325的一端与主轴组件310转动连接,另一端与第一连接架321滑动连接。第一支撑臂323相对于主轴组件310转动的旋转轴心与第一导杆臂325相对于主轴组件310转动的旋转轴心不同,且相互平行。第二支撑臂324的一端与主轴组件310转动连接,第二支撑臂324的另一端与第二连接架322通过二者上设置的第二弧形滑槽342以及与第二弧形滑槽342滑动配合的第二弧形臂344转动连接。第二导杆臂326的一端与主轴组件310转动连接,另一端与第二连接架322滑动连接。第二支撑臂324相对于主轴组件310转动的旋转轴心与第二导杆臂326相对于主轴组件310转动的旋转轴心不同,且相互平行。支撑组件330包括分别位于主轴组件310两侧、并用于支撑柔性屏100的第一支撑板332和第二支撑板333,第一支撑板332与位于同一侧的第一支撑臂323固定,第二支撑板333与位于同一侧的第二支撑臂324固定。第一连接架321和第二连接架322相向转动时,第一连接架321和第二连接架322分别向远离第一导杆臂325和第二导杆臂326的方向滑动,第一支撑臂323和第二支撑臂324分别相对第一连接架321和第二连接架322转动,使第一支撑板332和第二支撑板333的靠近主轴组件310的一端分别向远离主轴组件310的方向运动,以使转轴机构300在折叠状态时,第一支撑板332与第二支撑板333用于支撑柔性屏100的一面与主轴组件310呈锐角,并与主轴组件310共同围成容屏空间。
图8为本申请实施例提供的一种转轴机构的主轴组件、第一导杆臂、第一支撑臂和第一连接架的连接简图。
如图8所示,主轴组件310与第一支撑臂323、第一导杆臂325和第一连接架321形成一个导杆机构,同理,主轴组件310与第二支撑臂324、第二导杆臂326和第二连接架322形成一个导杆机构,第一支撑板332和第二支撑板333分别固定在第一支撑臂323和第二支撑臂324上,并可分别随第一支撑臂323和第二支撑臂324转动,在转轴机构300切换到折叠状态时,第一支撑板332和第二支撑板333之间可以形成用于供柔性屏100折叠的一端膨大的容屏空间,第一支撑板332与第一支撑臂323强耦合,第一支撑板332的转动角度与第一支撑臂323转动的角度一致,第二支撑板333与第二支撑臂324强耦合,第二支撑板333的转动角度与第二支撑臂324转动的角度一致,可降低因第一支撑板332与第一支撑臂323之间的相对位置不稳定以及第二支撑板333与第二支撑臂324之间的相对位置不稳定而造成的第一支撑板332和第二支撑板333之间的夹角公差,另外,第一支撑板332的运动只需由第一支撑臂323的转动来控制,第二支撑板333的运动只需由第二支撑臂324的转动来控制,缩短了控制第一支撑板332和第二支撑板333运动的控制链,利于对第一支撑板332和第二支撑板333的运动进行更为精确的控制,第一支撑板332和第二支撑板333之间的夹角更为稳定,公差更小,可使形成的容屏空间的形态更为稳定,可降低柔性屏100损坏的风险。此外,第一连接架321与第一支撑臂323通过第一弧形滑槽341和 第一弧形臂343转动连接,第一连接架321相对于第一支撑臂323转动的旋转轴心位于第一连接架321和第一支撑臂323的外侧,第二连接架322与第二支撑臂324通过第二弧形滑槽342和第二弧形臂344转动连接,第二连接架322相对于第二支撑臂324转动的旋转轴心位于第二连接架322和第二支撑臂324的外侧,在转轴机构300切换到折叠状态时,利于使第一支撑臂323连接第一连接架321的一端以及第二支撑臂324连接第二连接架322的一端向中部靠拢,可增大第一支撑臂323和紧固连接在第一支撑臂323上的第一支撑板332以及第二支撑臂324和紧固连接在第二支撑臂324上的第二支撑板333的转动角度,使第一支撑板332和第二支撑板333之间的夹角增大,第一支撑板332、第二支撑板333与主轴组件310之间形成的容屏空间增大,在第一导杆臂325、第二导杆臂326、第一支撑臂323和第二支撑臂324与主轴组件310的配合关系不变,且第一导杆臂325、第二导杆臂326、第一连接架321和第二连接架322的配合关系不变的情况下,增大容屏空间可不再设置使第一支撑板332与第一支撑臂323相对转动以及使第二支撑板333与第二支撑臂324相对转动的转动连接结构,转轴机构300的结构更加简单,装配更加方便。
下面通过具体实施例对本申请实施例提供的转轴机构300的实现方式进行阐述。
如图3所示,本申请实施例中,包括主轴组件310、折叠组件320和支撑组件330,折叠组件320可以相对主轴组件310旋转以使转轴机构300在展开状态与折叠状态之间切换。可以理解的是,折叠组件320可相对主轴组件310折叠和展开,并用于紧固连接第一壳体210和第二壳体220,支撑组件330安装在折叠组件320上,用于支撑柔性屏100。
如图5、图6所示,折叠组件320包括导杆臂组、支撑臂组和连接架组。导杆臂组包括第一导杆臂325和第二导杆臂326,支撑臂组包括第一支撑臂323和第二支撑臂324,连接架组包括第一连接架321和第二连接架322,第一导杆臂325、第一支撑臂323和第一连接架321分布于主轴组件310的一侧,第二导杆臂326、第二支撑臂324和第二连接架322分布于主轴组件310的另一侧。第一支撑臂323的一端与主轴组件310转动连接,第一支撑臂323的另一端与第一连接架321通过二者上设置的第一弧形滑槽341以及与第一弧形滑槽341滑动配合的第一弧形臂343转动连接。第一导杆臂325的一端与主轴组件310转动连接,另一端与第一连接架321滑动连接。第一支撑臂323相对于主轴组件310转动的旋转轴心与第一导杆臂325相对于主轴组件310转动的旋转轴心不同,且相互平行。第二支撑臂324的一端与主轴组件310转动连接,第二支撑臂324的另一端与第二连接架322通过二者上设置的第二弧形滑槽342以及与第二弧形滑槽342滑动配合的第二弧形臂344转动连接。第二导杆臂326的一端与主轴组件310转动连接,另一端与第二连接架322滑动连接。第二支撑臂324相对于主轴组件310转动的旋转轴心与第二导杆臂326相对于主轴组件310转动的旋转轴心不同,且相互平行。
可以理解的是,第一连接架321远离第一支撑臂323的一端用于与第一壳体210紧固连接,第二连接架322远离第二支撑臂324的一端用于与第二壳体220紧固连接。
需要说明的是,可在第一支撑臂323上设置第一弧形滑槽341,第一连接架321 上设置第一弧形臂343;也可在第一支撑臂323上设置第一弧形臂343,第一连接架321上设置第一弧形滑槽341。可在第二支撑臂324上设置第二弧形滑槽342,第二连接架322上设置第二弧形臂344;也可在第二支撑臂324上设置第二弧形臂344,第二连接架322上设置第二弧形滑槽342。
示例性的,第一弧形滑槽341设于第一支撑臂323上,第一弧形臂343设于第一连接架321上,第二弧形滑槽342设于第二支撑臂324上,第二弧形臂344设于第二连接架322上。
可以理解的是,第一弧形滑槽341和第二弧形滑槽342可以为四分之一圆弧槽、三分之一圆弧槽、二分之一圆弧槽等,第一弧形臂343和第二弧形臂344可为四分之一圆弧臂、三分之一圆弧臂、二分之一圆弧臂等,第一弧形滑槽341、第二弧形滑槽342、第一弧形臂343和第二弧形臂344的形状和位置可根据应用场景的实际情况进行调整。
第一弧形滑槽341的各侧槽壁可为一体式的结构,如此,可以降低因装配形成第一弧形滑槽341造成的公差。第一弧形滑槽341也可通过具有弧形凹陷部的第一结构件和具有弧形凸起部的第二结构件拼接形成,第一结构件的弧形凹陷部与第二结构件的弧形凸起部间隔,并限定出第一弧形滑槽341,这样,第一弧形滑槽341形成较为容易。
第二弧形滑槽342可参照第一弧形滑槽341设置。第二弧形滑槽342的各侧槽壁也可为一体式的结构,如此,可以降低因装配形成第二弧形滑槽342造成的公差。第二弧形滑槽342也可通过具有弧形凹陷部的第三结构件和具有弧形凸起部的第四结构件拼接形成,第三结构件的弧形凹陷部与第四结构件的弧形凸起部间隔,并限定出第二弧形滑槽342,这样,第二弧形滑槽342形成较为容易。
第一连接架321绕第一支撑臂323转动的旋转轴心位于第一连接架321和第一支撑臂323朝向柔性屏100一侧的外部,第二连接架322绕第二支撑臂324转动的旋转轴心位于第二连接架322和第二支撑臂324朝向柔性屏100一侧的外部。
如图8所示,主轴组件310与第一支撑臂323、第一导杆臂325和第一连接架321形成一个导杆机构,第一支撑臂323和第一导杆臂325相对于主轴组件310转动的过程中,可带动第一连接架321转动,并可使第一连接架321沿第一导杆臂325滑动,以改变第一连接架321与第一导杆臂325绕主轴组件310旋转的旋转轴心之间的间距。如图8中所示,在转轴机构300切换到折叠状态的过程中,第一导杆臂325和第一支撑臂323均沿图8中的顺时针方向转动,第一连接架321向远离第一导杆臂325绕主轴组件310旋转的旋转轴心的方向滑动,在转轴机构300切换到展开状态的过程中,第一导杆臂325和第一支撑臂323均沿图8中的逆时针方向转动,第一连接架321向靠近第一导杆臂325绕主轴组件310旋转的旋转轴心的方向滑动。
同上述主轴组件310与第一支撑臂323、第一导杆臂325和第一连接架321的配合关系和运动原理,主轴组件310与第二支撑臂324、第二导杆臂326和第二连接架322形成一个导杆机构,第二支撑臂324和第二导杆臂326相对于主轴组件310转动的过程中,可带动第二连接架322转动,并可使第二连接架322沿第二导杆臂326滑动,以改变第二连接架322与第二导杆臂326绕主轴组件310旋转的旋转轴心之间的 间距。在转轴机构300切换到折叠状态的过程中,第二导杆臂326与第一导杆臂325相向转动,第二支撑臂324与第一支撑臂323相向转动,第二连接架322与第一连接架321相向转动。
如图7所示,本申请实施例中,支撑组件330包括分别位于主轴组件310两侧、并用于支撑柔性屏100的第一支撑板332和第二支撑板333,第一支撑板332与位于同一侧的第一支撑臂323固定,第二支撑板333与位于同一侧的第二支撑臂324固定。
可以理解的是,第一支撑板332和第二支撑板333可以通过粘接、焊接、紧固件连接或者一体成型等方式分别与第一支撑臂323和第二支撑臂324紧固连接。
在本申请的一些实施例中,第一支撑板332和第二支撑板333靠近主轴组件310的一端可以向主轴组件310的中轴线方向延伸至仅留出供第一支撑板332和第二支撑板333转动的间隙的位置。此时,处于折叠状态的转轴机构300第一支撑板332、第二支撑板333与主轴组件310之间形成类似三角形的容屏空间。
当然,在本申请的一些实施例中,第一支撑板332和第二支撑板333靠近主轴组件310的一端之间也可以留出用于支撑柔性屏100的其他结构的空间。
在本申请实施例中,第一连接架321和第二连接架322相向转动时,第一连接架321和第二连接架322分别向远离第一导杆臂325和第二导杆臂326的方向滑动,第一支撑臂323和第二支撑臂324分别相对第一连接架321和第二连接架322转动,使第一支撑板332和第二支撑板333的靠近主轴组件310的一端分别向远离主轴组件310的方向运动,以使转轴机构300在折叠状态时,第一支撑板332与第二支撑板333用于支撑柔性屏100的一面与主轴组件310呈锐角,并与主轴组件310共同围成容屏空间。
可以理解的是,转轴机构300在折叠状态时,第一连接架321和第二连接架322朝向柔性屏100的一面与主轴组件310之间的夹角可为直角(允许存在少许偏差),也可为钝角。
