铰链组件及可折叠的电子设备
本申请要求于2021年11月12日提交中国专利局、申请号为202111339253.8，申请名称为“铰链组件及可折叠的电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，特别涉及一种铰链组件及可折叠的电子设备。
背景技术
随着手机等移动设备的不断发展，用户对大屏幕手机的需求越来越强烈，但是大屏幕手机存在携带不方便的显著问题，因此，可折叠电子设备，比如折叠屏手机成为提升携带便利性的主要方向。其中，为了满足不同用户的差异化需求，各种屏幕内折和屏幕外折形态的折叠屏手机应运而生。
目前，折叠屏手机一般包括两个结构件，两个结构件之间通过铰链组件相连，使得两个结构件能够相对发生转动，进而使两个结构件可以相互折叠或展开。为了能够让手机在任意角度悬停，铰链组件上通常设置阻尼机构，阻尼机构包括摆臂、凸轮以及弹簧，其中，所述凸轮包括上凸轮和下凸轮，所述上凸轮固定在所述摆臂上，所述下凸轮与所述上凸轮啮合连接，所述弹簧一端固定，另一端与所述下凸轮抵接，所述弹簧用于支撑所述下凸轮。折叠时，转动所述摆臂带动所述上凸轮旋转，所述下凸轮受到所述上凸轮的压力向下运动，并压缩所述弹簧，当折叠到适当角度时，停止转动所述摆臂，依靠所述上凸轮和所述下凸轮之间的摩擦力，以及所述弹簧的支撑力，使所述摆臂悬停在任意角度。
然而，在上述的折叠过程中，折叠屏手机悬停的控制完全依靠上凸轮和下凸轮之间的摩擦作用，这样上凸轮和下凸轮的磨损较快，从而大大缩短了折叠屏手机的使用寿命。
发明内容
本申请实施例提供一种铰链组件及可折叠的电子设备，实现了电子设备在固定角度悬停，并且结构简单，解决了上凸轮和下凸轮之间磨损快的技术问题。
本申请实施例第一方面提供一种铰链组件，包括：主轴机构以及设置在所述主轴机构上的弹性组件和转动机构；其中，所述转动机构和所述弹性组件中的其中一个与所述主轴机构固定连接，所述转动机构和所述弹性组件中的另一个与所述主轴机构转动连接；所述转动机构和所述弹性组件中的其中一个上设有多个凸起，所述转动机构和所述弹性组件中的另一个上设有多个与所述凸起配合的凹槽；所述转动机构旋转至一个预设位置时，所述多个凸起中的部分所述凸起卡合在所述多个凹槽中的部分所述凹槽中，所述多个凸起中的其余所述凸起抵在所述弹性组件和所述转动机构之间；所 述转动机构旋转至另一个所述预设位置时，所述多个凸起中的另外一部分所述凸起中的至少部分所述凸起卡合在所述多个凹槽中的另外一部分所述凹槽中的至少部分所述凹槽中，所述多个凸起中其余所述凸起抵在所述弹性组件和所述转动机构之间。
本申请实施例提供的铰链组件，通过设置弹性组件，并且在弹性组件和转动机构的其中一个上设有多个凸起，在弹性组件和转动机构中的另一个上设有多个与凸起配合的凹槽，可以通过凸起和凹槽配合可以实现铰链组件在固定角度悬停，且在悬停状态下凸起卡合在凹槽内，可以保证悬停的稳定性；通过凸起和凹槽的配合实现铰链组件的悬停，这样可以避免弹簧、上凸轮和下凸轮的使用，从而可以减少上凸轮和下凸轮之间的磨损，另外减少弹簧的使用可以节约主轴机构轴向的安装空间，从而简化铰链组件的结构，降低成本。
作为解释说明，在使用过程中，折叠终端一般不需要在任意角度悬停，在某些角度悬停的需要较大，在某些角度不需要悬停。因此通过在铰链组件上设计凸起和凹槽，利用凸起和凹槽之间的卡合作用，可以实现铰链组件的固定角度悬停，从而减少铰链组件中弹性组件和转动机构之间的磨损。
在一种可能的实现方式中，所述转动机构包括第一摆臂和第二摆臂，所述第一摆臂和所述第二摆臂分别位于所述主轴机构的两侧；所述弹性组件设置在所述第一摆臂和所述第二摆臂之间；所述第一摆臂和所述弹性组件的第一端中的其中一个上设有多个所述凸起，所述第一摆臂和所述弹性组件的第一端中的另一个上设有多个所述凹槽；所述第二摆臂与所述弹性组件的第二端中的其中一个上设有多个所述凸起，所述第二摆臂与所述弹性组件的第二端中的另一个上设有多个所述凹槽。
本申请实施例提供的铰链组件，通过在第一摆臂上设置第一连接部，第二摆臂上设置第二连接部，然后将弹片设置在第一连接部和第二连接部之间，这样可以方便的将弹片安装在第一摆臂和第二摆臂上，并保证弹片和第一摆臂以及第二摆臂的可靠连接。在一种可能的实现方式中，所述弹性组件的第一端上设置的所述凸起为第一凸起，所述弹性组件的第二端上设置的所述凸起为第二凸起，且所述第一凸起和所述第二凸起沿所述主轴机构的中轴线对称设置；所述第一摆臂上设置的所述凹槽为第一凹槽，所述第二摆臂上设置的所述凹槽为第二凹槽，且所述第一凹槽和所述第二凹槽沿所述主轴机构的中轴线对称设置。
在一种可能的实现方式中，所述主轴机构包括第一支撑杆和第二支撑杆；所述弹性组件的第一端和第二端分别穿设在所述第一支撑杆和所述第二支撑杆上，且所述弹性组件与所述第一支撑杆和所述第二支撑杆均转动连接；所述第一摆臂的一端穿设在所述第一支撑杆上，并与所述弹性组件的第一端相对，且所述第一摆臂与所述第一支撑杆固定连接；所述第二摆臂的一端穿设在所述第二支撑杆上，并与所述弹性组件的第二端相对，且所述第二摆臂与所述第二支撑杆固定连接。
在一种可能的实现方式中，所述弹性组件包括多个弹片，每个所述弹片的第一端均设置一个所述第一凸起，每个所述弹片的第二端均设置一个所述第二凸起；所述弹片的第一端和第二端分别套设在所述第一支撑杆和所述第二支撑杆上，且与所述第一支撑杆和所述第二支撑杆转动连接；所述第一摆臂上设置有第一连接部，所述第一凹槽设置在所述第一连接部上；所述第二摆臂上设置有第二连接部，所述第二凹槽设置 在所述第二连接部上；多个所述弹片均设置在所述第一连接部和所述第二连接部之间。
本申请实施例提供的铰链组件，通过将弹性组件设计成包括多个弹片的结构，可以使铰链组件至少在两个位置悬停。一般情况下，可折叠的电子设备至少需要能够完全展开和完全折叠，也就是说，可折叠的电子设备至少需要在两个角度悬停。通过设置多个弹片可以保证可折叠的电子设备可以在两个角度悬停，然后通过增加弹片的数量可以增加可折叠的电子设备的悬停角度，简单方便。
在一种可能的实现方式中，多个所述弹片上的至少部分所述第一凸起在所述第一支撑杆的轴向上的正投影沿着所述第一支撑杆的周向间隔分布；多个所述弹片上的至少部分所述第二凸起在所述第二支撑杆的轴向上的正投影沿着所述第二支撑杆的周向间隔分布；所述第一摆臂上设置的多个所述第一凹槽在所述第一支撑杆的轴向上的正投影重合；所述第二摆臂上设置的多个所述第二凹槽在所述第二支撑杆的轴向上的正投影重合。
本申请实施例提供的铰链组件，通过多个弹片上的第一凸起在主轴机构的轴向上的正投影沿着第一支撑杆的周向间隔分布；多个弹片上的第二凸起在主轴机构的轴向上的正投影沿着第二支撑杆的周向间隔分布；这样不同的弹片就可以控制不同的悬停位置，从而为铰链组件的悬停提供多个位置，从而使可折叠的电子设备可以在不同的角度悬停，以满足客户需求。
在一种可能的实现方式中，所述第一连接部包括多个间隔设置且穿设在所述第一支撑杆上的第一子连接部，所述第二连接部包括多个间隔设置且穿设在所述第二支撑杆上的第二子连接部；其中，至少部分所述弹片的第一端设置在相邻两个所述第一子连接部之间，以及至少部分所述弹片的第二端设置在相邻两个所述第二子连接部之间。
本申请实施例提供的铰链组件，通过将第一连接部设计成包括多个间隔设置的第一子连接部的结构，将第二连接部设计成包括多个间隔设置的第二子连接部的结构，可以给弹片提供更多的安装位置，从而可以通过设置更多的弹片，进而可以设置更多的悬停角度，以适应用户的需求。
在一种可能的实现方式中，所述第一子连接部和所述第二子连接部分的数量与所述弹片的数量相同；部分所述弹片的第一端设置在相邻两个所述第一子连接部之间，以及部分所述弹片的第二端设置在相邻两个所述第二子连接部之间；部分所述弹片的第一端和第二端分别设置在最外侧的其中一个所述第一子连接部和所述第二子连接部的外侧；每个所述第一子连接部上均设有一个所述第一凹槽，且多个所述第一子连接部上的所述第一凹槽在所述第一支撑杆的轴向上的正投影重合；每个所述第二子连接部上均设有一个所述第二凹槽，且多个所述第二子连接部上的所述第二凹槽在所述第二支撑杆的轴向上的正投影重合。
本申请实施例提供的铰链组件，通过将第一子连接部或者第二子连接部分的数量设计的与弹片的数量相同，这样可以充分利用第一摆臂和第二摆臂给弹片提供的安装空间，从而可以在相同安装空间内安装最多的弹片，以使可折叠的电子设备可以在最多的角度悬停，以满足客户需求。
本申请实施例提供的铰链组件，多个所述第一子连接部上的所述第一凹槽在所述主轴机构的轴向上的正投影重合，可以理解为多个第一凹槽设置在沿主轴机构轴向的 一条直线上；多个所述第二子连接部上的所述第二凹槽在所述主轴机构的轴向上的正投影重合，可以理解为多个第二凹槽设置在沿主轴机构轴向的一条直线上。这样通过将多个第一凹槽设置在沿主轴机构轴向的一条直线上，将多个第二凹槽设置在沿主轴机构轴向的一条直线上，可以保证多个第一凹槽相对于弹片上多个第一凸起的初始位置均相同，多个第二凹槽相对于弹片上多个第二凸起的初始位置均相同，这样旋转第一摆臂和第二摆臂时，就可以保证第一凹槽和第二凹槽的起点位于沿主轴机构的同一直线上，换句话说就是，第一凹槽和第二凹槽的起点相同，因此只需要将多个弹片上第一凸起和第二凸起沿主轴机构的周向的设置在不同的位置，就可以控制铰链组件的悬停角度。这样相对于通过控制第一凹槽、第二凹槽、第一凸起以及第二凸起四个变量的位置，来控制铰链组件的悬停角度要更容易一些。本申请实施例第二方面提供一种铰链组件，包括：主轴机构以及设置在所述主轴机构上的弹性组件和转动机构；其中，所述转动机构和所述弹性组件中的其中一个与所述主轴机构固定连接，所述转动机构和所述弹性组件中的另一个与所述主轴机构转动连接；所述转动机构和所述弹性组件中的其中一个上设有凸起，所述转动机构和所述弹性组件中的另一个上设有多个与所述凸起配合的凹槽；所述转动机构旋转至一个预设位置时，所述凸起卡合在其中一个所述凹槽中；所述转动机构旋转至另一个所述预设位置时，所述凸起卡合在另一个所述凹槽中。
本申请实施例提供的铰链组件，通过设置弹性组件，并且在弹性组件和转动机构的其中一个上设有凸起，在弹性组件和转动机构中的另一个上设有多个与凸起配合的凹槽，可以通过凸起和凹槽配合可以实现铰链组件在固定角度悬停，且在悬停状态下凸起卡合在凹槽内，可以保证悬停的稳定性；通过凸起和凹槽的配合实现铰链组件的悬停，这样可以避免弹簧、上凸轮和下凸轮的使用，从而可以减少上凸轮和下凸轮之间的磨损，另外减少弹簧的使用可以节约主轴机构轴向的安装空间，从而简化铰链组件的结构，降低成本。

当然，在一些实施例中，该可折叠的电子设备也可以是笔记本电脑，笔记本电脑也可以包括第一结构件和第二结构件，第一结构件和第二结构件能够相向转动至相互层叠，使笔记本电脑处于折叠状态，反之，第一结构件和第二结构件由层叠状态起，相背转动至无法转动时，笔记本电脑处于展开状态。其中，在展开状态时，第一结构件上的部分可折叠第一显示屏可以用于图像等的显示，而第二结构件上的部分可折叠第一显示屏可以作为虚拟键盘。
下面对本申请实施例中，用于上述折叠屏手机100的铰链组件30a进行详细说明。
如图6所示，铰链组件30a可以包括主轴机构31以及设置在主轴机构31上的弹性组件32和转动机构33；其中，转动机构33和弹性组件32中的其中一个与主轴机构31固定连接，转动机构33和弹性组件32中的另一个与主轴机构31转动连接。
如图6所示，转动机构33可以包括第一摆臂331和第二摆臂341，第一摆臂331和第二摆臂341位于主轴机构31的两侧，且相对主轴机构31对称设置。第一摆臂331和第二摆臂341可以沿着图6中所示的两个虚线箭头相对弹性组件32转动。
在本实施例中，如图6所示，主轴机构31可以具有第一支撑杆311和第二支撑杆312，弹性组件32转动连接在主轴机构31上，且设置在第一摆臂331和第二摆臂341之间，弹性组件32的第一端和弹性组件32的第二端分别穿设在第一支撑杆311和第二支撑杆312上，第一摆臂331的一端穿设在第一支撑杆311上，并与弹性组件32的第一端相对，第二摆臂341的一端穿设在第二支撑杆312上，并与弹性组件32的第二端相对。其中，第一摆臂331与第一支撑杆311固定连接，第二摆臂341与第二支撑杆312固定连接。
在本实施例中，如图7所示，第一支撑杆311的一端上固定有第一齿轮313，第二支撑杆312的一端固定有第二齿轮314；第一摆臂331和第二摆臂341之间设置有两个相互啮合且分别与第一齿轮313和第二齿轮314啮合的第三齿轮315和第三齿轮316，由于第一支撑杆311和第一摆臂331固定连接，第一齿轮313又固定在第一支撑杆311上，所以旋转第一摆臂331可以带动第一支撑杆311转动，进而带动第一齿轮313转动。
下面以第一摆臂331沿顺时针方向旋转为例对第一齿轮313、第二齿轮314、第三齿轮315和第三齿轮316之间的联动过程进行说明。第一摆臂331沿顺时针方向旋转，则带动第一齿轮313沿顺时针方向旋转，然后带动与第一齿轮313啮合的一个第三齿轮315沿逆时针方向旋转，然后带动与第二齿轮314啮合的第三齿轮316沿顺时针旋转，最后带动第二齿轮314沿逆时针旋转，由于第二齿轮314与第二支撑杆312固定连接，第二支撑杆312与第二摆臂341固定连接，因此第二摆臂341沿逆时针旋转。由上述可知，第一齿轮313和第二齿轮314可以同步转动，且转动方向相反。也就是说，第一摆臂331和第二摆臂341可以同步转动，且转动方向相反。
参见图7所示，第一摆臂331和第二摆臂341处于完全展开状态时，第一摆臂331所在平面和第二摆臂341所在平面之间的夹角为180°；第一摆臂331和第二摆臂341处于完全折叠态时，第一摆臂331所在平面和第二摆臂341所在平面之间的夹角可以为0，且第一摆臂331和第二摆臂341分别以主轴机构31为轴向相互靠近的方向旋转 了90°。
需要说明的是，第一摆臂331和第二摆臂341处于完全折叠态时，第一摆臂331所在平面和第二摆臂341所在平面之间的夹角包括但不限于为零，在一些实施例中，例如：第一显示屏10为水滴屏时，第一摆臂331和第二摆臂341在完全折叠状态时，第一摆臂331和第二摆臂341所在平面的夹角可以大于零度，此时，第一摆臂331和第二摆臂341以主轴机构31为轴向相互靠近的方向旋转的角度大于90°。
本申请实施例中，如图8所示，铰链组件30a包括：弹性组件32、第一摆臂331、第二摆臂341、第一支撑杆311和第二支撑杆312。弹性组件32设置在第一摆臂331和第二摆臂341之间，第一支撑杆311和第二支撑杆312分别穿设在第一摆臂331、第二摆臂341以及弹性组件32上。其中，弹性组件32上设有凸起327，位于弹性组件32的第一端的凸起327为第一凸起323，位于弹性组件32的第二端的凸起327为第二凸起324，且第一凸起323和第二凸起324沿主轴机构31的中轴线对称设置。第一摆臂331和第二摆臂341上均设置有凹槽332，其中，位于第一摆臂331上的凹槽332为第一凹槽3312，位于第二摆臂341上的凹槽332为和第二凹槽3412，且第一凹槽3312和第二凹槽3412沿主轴机构31的中轴线对称设置。其中，弹性组件32靠近第一摆臂331的一端为弹性组件32的第一端，弹性组件32靠近第二摆臂341的一端为弹性组件32的第二端。
如图8所示，第一摆臂331上设置有第一连接部3311，第一连接部3311还可以包括八个间隔设置的第一子连接部3311a，八个第一子连接部3311a沿主轴机构31的轴向分布，且八个第一子连接部3311a均穿设在第一支撑杆311上，并与第一支撑杆311固定连接；第二摆臂341上设置有第二连接部3411，第二连接部3411包括八个间隔设置的第二子连接部3411a，八个第二子连接部3411a沿主轴机构31的轴向分布，且多个第二子连接部3411a穿设在第二支撑杆312上，并与第二支撑杆312固定连接。每个第一子连接部3311a上均设有一个第一凹槽3312，每个第二子连接部3411a上均设有一个第二凹槽3412。
如图8所示，弹性组件32包括位于上部的弹片32a、弹片32b、弹片32c、弹片32d和位于下部的弹片32a、弹片32b、弹片32c、弹片32d。弹片32a、弹片32b、弹片32c、弹片32d均可以设置在第一连接部3311和第二连接部3411之间。

如图8所示，本实施例中，第一安装孔3311b和第二安装孔3411b为长圆孔，具 体的，该长圆孔的两个相对的端面为相互平行的平面，另外两个相对的端面为圆弧形面。第一支撑杆311与第一连接部3311连接的部分横截面与第一安装孔3311b的形状相同，这样可以实现第一支撑杆311和第一连接部3311的固定连接，以使转动第一摆臂331时，第一支撑杆311可以随着第一摆臂331一起转动；第二支撑杆312与第二连接部3411连接的部分的横截面与第二安装孔3411b的形状形同，这样可以实现第二支撑杆312和第二连接部3411的固定连接，以使转动第二摆臂341时，第二支撑杆312可以随着第二摆臂341一起转动。
如图8所示，第一连接孔325和第二连接孔326的形状为圆形，第一连接孔325和第二连接孔326的内径大于第一安装孔3311b和第二安装孔3411b的内径，并且第一连接孔325和第二连接孔326的内径大于第一支撑杆311和第二支撑杆312的外径，从而保证弹片可以和第一支撑杆311和第二支撑杆312转动连接。
需要说明的是，第一安装孔3311b和第二安装孔3411b的形状包括但不限于为长圆孔，在一些示例中，第一安装孔3311b和第二安装孔3411b也可以为其它形状，只要是能够实现第一连接部3311和第一支撑杆311固定连接，第二连接部3411和第二支撑杆312固定连接即可。第一连接孔325和第二连接孔326的形状包括但不限于为圆形，在一些示例中，第一连接孔325和第二连接孔326也可以为其它形状，例如：方形、椭圆形、五边形等，只要是能够保证弹片和第一支撑杆311以及第二支撑杆312固定连接即可。
如图8所示，本实施例中，弹片、第一子连接部3311a和第二子连接部3411a的数量均为八个，装配时，每个弹片的第一端321均套设在第一支撑杆311上，并与第一支撑杆311转动连接，每个第一子连接部3311a套设在第一支撑杆311上，并与第一支撑杆311固定连接；每个弹片的第二端322均套设在第二支撑杆312上，并与第二支撑杆312转动连接；每个第二子连接部3411a均套设在第二支撑杆312上，并与第二支撑杆312固定连接。第一凹槽3312位于第一子连接部3311a的顶端端面上，第二凹槽3412位于第二子连接部3411a的顶端端面上，第一凸起323和第一凹槽3312相对设置，从而在转动第二摆臂331时，第一凸起323可以卡合在第一凹槽3312内；第二凸起324和第二凹槽3412相对设置，从而在转动第二摆臂341时，第二凸起324可以卡合在第二凹槽3412内。
如图10所示，本实施例中，第一摆臂331和第二摆臂341以主轴机构31的中心轴线为对称轴相互对称，第一子连接部3311a和第二子连接部3411a的数量和形状均相同，第一子连接部3311a的数量和弹片的数量相同，并且相邻两个第一子连接部3311a之间存在第一间隙d1，相邻两个第二子连接部3411a之间存在第二间隙d2，d1和d2宽度相等，在位于同一平面的第一间隙和第二间隙内设有一个弹片，另外，在位于第一摆臂331最外侧的第一子连接部3311a和位于第二摆臂341最外侧的第二子连接部3411a上也设置有一个弹片。
结合图8和图10所示，第一摆臂331的第一连接部3311上设有八个第一子连接部3311a，并且，每四个第一子连接部3311a为一组，两组第一子连接部3311a之间的间隙为第三间隙d3，第二摆臂341的第二连接部3411上设有八个第二子连接部3411a，并且，每四个第二子连接部3411a为一组，两组第二子连接部3411a之间的间隙为第 四间隙d4，其中d3与d4宽度相等。八个弹片中位于上部的四个弹片和位于下部的四个弹片上凸起的排列方式相同。下面以位于上部的弹片32a、弹片32b、弹片32c、弹片32d，以及位于上部的四个第一子连接部3311a和四个第二子连接部3411a为例进行说明。
如图11所示，在每个第一子连接部3311a上均设有一个第一凹槽3312，且四个第一子连接部3311a上的第一凹槽3312在主轴机构31的轴向上的正投影重合；每个第二子连接部3411a上均设有一个第二凹槽3412，且四个第二子连接部3411a上的第二凹槽3412在主轴机构31的轴向上的正投影重合。弹片32a、弹片32b、弹片32c和弹片32d上的四个第一凸起323在第一支撑杆311的轴向上的正投影沿着第一支撑杆311的周向间隔分布；弹片32a、弹片32b、弹片32c和弹片32d上的四个第二凸起324在第二支撑杆312的轴向上的正投影沿着第二支撑杆312的周向间隔分布。需要说明的是，每个弹片上的第一凸起323和第二凸起324均对称设置。弹片32a、弹片32b、弹片32c和弹片32d从上到下依次设置在第一子连接部3311a和第二子连接部3411a上。其中，弹片32a位于第一摆臂331和第二摆臂341的顶端；弹片32b设置在从顶端开始的第一个第一间隙和第一个第二间隙内，弹片32c设置在从顶端开始的第二个第一间隙和第二个第二间隙内，弹片32d设置在从顶端开始的第三个第一间隙和第三个第二间隙内。弹片32a、弹片32b、弹片32c和弹片32d分别控制一个预设位置。在实际操作过程中，当第一摆臂331和第二摆臂341旋转至一个预设位置时，弹片32a的第一凸起323可以卡合在与弹片32a对应的第一凹槽3312中，弹片32b、弹片32c和弹片32d的第一凸起323抵在弹片的第一端321和第一摆臂331之间，弹片32a的第二凸起324卡合在与弹片32a对应的第二凹槽3412中，弹片32b、弹片32c和弹片32d的第二凸起324抵在弹片的第二端322和第二摆臂341之间。
在第一摆臂331和第二摆臂341旋转至另一个预设位置时，弹片32b的第一凸起323可以卡合在与弹片32b对应的第一凹槽3312中，弹片32a、弹片32c和弹片32d的第一凸起323抵在弹片的第一端321和第一摆臂331之间，弹片32b的第二凸起324卡合在弹片32b对应的第二凹槽3412中，弹片32a、弹片32c和弹片32d的第二凸起324抵在弹片的第二端322和第二摆臂341之间。
当第一摆臂331和第二摆臂341旋转至第三个预设位置时，弹片32c的第一凸起323可以卡合在弹片32c对应的第一凹槽3312中，弹片32a、弹片32b和弹片32d的第一凸起323抵在弹片的第一端321和第一摆臂331之间，弹片32c的第二凸起324卡合在弹片32c对应的第二凹槽3412中，弹片32a、弹片32b和弹片32d的第二凸起324抵在弹片的第二端322和第二摆臂341之间。
当第一摆臂331和第二摆臂341旋转至第四个预设位置时，弹片32d的第一凸起323可以卡合在弹片32d对应的第一凹槽3312中，弹片32a、弹片32b和弹片32c的第一凸起323抵在弹片的第一端321和第一摆臂331之间，弹片32d的第二凸起324卡合在弹片32d对应的第二凹槽3412中，弹片32a、弹片32b和弹片32c的第二凸起324抵在弹片的第二端322和第二摆臂341之间。
需要说明的是，可折叠屏手机至少需要能够完全展开和完全折叠，因此第一凹槽和第二凹槽均至少为两个，而弹片可以为两个。在本实施例中，弹性组件至少可以包 括两个弹片，其中，两个弹片中的每个弹片的第一端设置一个第一凸起，两个第一凸起在主轴机构轴向上的正投影之间的夹角可以为90°；两个弹片中的每个弹片的第二端设置一个第二凸起，其中，两个第二凸起在主轴机构轴向上的正投影之间的夹角可以为90°，第一摆臂上设置两个第一凹槽，其中，两个第一凹槽在主轴机构轴向上的正投影重合，第二摆臂上设置两个第二凹槽，其中，两个第二凹槽在主轴机构轴向上的正投影重合。
需要说明的是，在一些实施例中，例如：第一显示屏或第二显示屏为水滴屏时，两个第一凸起323在主轴机构31轴向上的正投影之间的夹角可以大于90°，两个第二凸起324在主轴机构31轴向上的正投影之间的夹角也可以大于90°。因此，两个第一凸起323在主轴机构31轴向上的正投影之间的夹角不构成对本申请技术方案保护范围的限制。
需要说明的是，第一子连接部3311a和第二子连接部3411a的数量包括但不限于八个，在一些示例中，也可以不设置第一子连接部3311a和第二子连接部3411a，或者分别设置两个、三个、四个、五个等第一子连接部3311a和第二子连接部3411a，第一子连接部3311a和第二子连接部3411a的具体数量可以根据具体情况具体设定，在此不再赘述。
在本实施例中，再参见图8所示，弹性组件32还包括限位组件35，其中，每个限位组件35均包括：一个限位件351、弹簧352、弹簧353，其中，弹簧352和弹簧353分别设置在限位件351的两端，且弹簧352和弹簧353的一端与弹片32a抵接，弹簧352和弹簧353的另一端与限位件351抵接；限位组件35设置在第一摆臂331和第二摆臂341的外侧，且限位件351的一面可以与第一支撑杆311和第二支撑杆312抵接，限位件351的另一面与弹簧352和弹簧353抵接；或者，限位组件35设置在相邻两个第一子连接部3311a和相邻两个第二子连接部3411a之间，且限位件351的一面与第一子连接部3311a和第二子连接部3411a抵接，限位件351的另一面与弹簧352和弹簧353抵接。
在本实施例中，设置在第一摆臂331和第二摆臂341的外侧的限位组件35可以避免弹片32a跟第一支撑杆311和第二支撑杆312直接接触，因为在装配铰链组件30a时，需要保证铰链组件30a的安装紧固性，所以如果弹片32a和第一支撑杆311以及第二支撑杆312直接接触，可能会导致弹片32a被挤压在第一摆臂331和第二摆臂341的外侧端面上，使第一摆臂331和第二摆臂341无法转动。而通过设置限位组件35，并且限位组件35上包括弹簧352和弹簧353，这样在保证铰链组件30a的安装紧固性的同时，还能保证弹片32a可以实现上下伸缩运动，以保证第一摆臂331和第二摆臂341可以转动。
通过设置限位组件35，可以限制弹片32a、第一支撑杆311、第二支撑杆312的位置，并且可以方便主轴机构31与第一摆臂331和第二摆臂341固定连接。另外，通过设置限位组件35，并且将弹片32a的两端分别与限位组件35中的弹簧352和弹簧353接触连接，安装时应使弹簧352和弹簧353处于压缩状态，这样才能够在第一凸起323卡合在第一凹槽3312内，且第二凸起324卡合在第二凹槽3412内时，弹簧352、353可以挤压弹片32a，以使弹片32a的第一凸起323卡合在第一凹槽3312内，第二 凸起324卡合在第二凹槽3412内。
由于弹簧352和弹簧353可以伸缩变形，因此，与弹簧352和弹簧353连接的弹片32a可以实现沿主轴机构轴向的运动，从而保证在第一摆臂331和第二摆臂341旋转至与弹簧352和弹簧353连接的弹片32a所对应预设位置时，弹片32a上的第一凸起323可以卡合在第一凹槽3312内，第二凸起324可以卡合在第二凹槽3412内；在第一摆臂331和第二摆臂341旋转至弹片32a对应预设位置之外时，与弹簧352和弹簧353连接的弹片上的第一凸起323脱离第一凹槽3312，并抵在第一摆臂331上，第二凸起324脱离第二凹槽3412，并抵在第二摆臂341上。
另外，通过设置限位组件35，可以减小弹片和第一摆臂331以及第二摆臂341之间的磨损，并且，可以保证第一摆臂331和第二摆臂341的平滑摆动，减少悬停时的卡顿感；另外，还能保证悬停时的稳定性，不会产生因卡合力小而导致无法悬停的问题。
在本实施例中，限位组件35的数量为两个，分别设置在位于第一摆臂331和第二摆臂341最外侧的弹片32a上和位于中部的弹片32a上。需要说明的是，限位组件35的数量包括但不限于两个，在一些实施例中，限位组件35可以设置多个，例如，限位组件35的数量可以和弹片的数量相同，这样每个弹片对应一个限位组件35，从而可以保证铰链组件30a折叠的流畅，并且悬停稳定。实际应用工程中，限位组件35的数量可以根据具体情况具体设定，在此不做赘述。
另外，在第一支撑杆311和第二支撑杆312与限位件351之间还可以设置垫片317，通过设置垫片317可以减少第一支撑杆311和第二支撑杆312与限位件351之间的磨损。
本实施例中，如图8所示，限位件351的两端分别设有第一通孔354和第二通孔355；第一支撑杆311插接于第一通孔354内，第二支撑杆312插接在第二通孔355内，以使限位件351与第一支撑杆311和第二支撑杆312均转动连接；第一支撑杆311上设置至少一个弹簧352，第二支撑杆312上设置至少一个弹簧353，这样可以使限位件351两端得到稳定支撑。
需要说明的是，限位件351上的第一通孔354和第二通孔355的形状可以和弹片上的第一连接孔325和第二连接孔326的形状相同，以保证将限位件351可以与第一支撑杆311和第二支撑杆312上转动连接。
通过在第一摆臂331和第二摆臂341上设置多个第一子连接部3311a和第二子连接部3411a，可以增加弹片的数量，进而可以增加悬停的角度，从而可以充分利用铰链组件30a在主轴机构31轴向上的安装空间，提高铰链组件30a在主轴机构31轴向上的空间利用率。
继续参见图8和图10所示，本实施例中的弹片为八个，且以第三间隙和第四间隙为分界线，将位于第三间隙和第四间隙上侧的四个弹片为一组进行说明，图12为本申请实施例提供的折叠屏手机的铰链组件中四个弹片在主轴机构轴向上的正投影的示意图。如图12所示，四个弹片上的第一凸起323在主轴机构31的轴向上的正投影沿着第一支撑杆311的周向间隔分布，其中相邻两个弹片上的第一凸起323之间的夹角为第一夹角a，第一夹角a的角度可以为10°、20°、30°45°等；四个弹片上的第二 凸起324在主轴机构31的轴向上的正投影沿着第二支撑杆312的周向间隔分布，相邻两个弹片上的第二凸起324之间的夹角为第二夹角b，第二夹角b的角度可以为10°、20°、30°45°等。
下面结合附图对折叠屏手机的折叠过程进行说明。
如图13所示，图13的剖面为图11中设置弹片32d的位置，第一摆臂331和第二摆臂341均位于折叠0°的位置，此时折叠屏手机处于完全展开状态，即第一摆臂331和第二摆臂341之间的夹角为180°，折叠屏手机在第一个预设位置悬停；将第一摆臂331和第二摆臂341沿着虚线箭头方向向内折叠至图14的位置，如图14所示，图14的剖面为图11中设置弹片32c的位置，第一摆臂331和第二摆臂341均折叠30°，此时第一摆臂331和第二摆臂341之间的夹角(图14中用c表示)为120°，折叠屏手机在第二个预设位置悬停；继续沿着虚线箭头方向向内折叠第一摆臂331和第二摆臂341至图15的位置，如图15所示，图15的剖面为图11中设置弹片32b的位置，此时第一摆臂331和第二摆臂341之间的夹角(图15中用c表示)为60°，折叠屏手机在第三个预设位置悬停；继续沿着虚线箭头方向向内折叠第一摆臂331和第二摆臂341至图16的位置，如图16所示，图16的剖面为图11中设置弹片32a的位置，此时第一摆臂331和第二摆臂341之间的夹角为0°，折叠屏手机在第四个预设位置悬停，并且此时折叠屏手机处于完全折叠状态。
在本实施例中，如图17和图18所示，铰链组件30a还可以包括：齿轮支架36，齿轮支架36的两端分别设有第一装配孔361和第二装配孔362；第一支撑杆311插接于第一装配孔361内，第二支撑杆312插接于第二装配孔362内，以使齿轮支架36与第一支撑杆311和第二支撑杆312均转动连接；齿轮支架36设置在第一摆臂331和第二摆臂341的外侧；齿轮支架36的一面与第一齿轮313和第二齿轮314抵接，齿轮支架36的另一面与第一摆臂331和第二摆臂341抵接。
另外，在本实施例中，结合图8、图17和图18所示，第一摆臂331与齿轮支架36连接的一端设置有止挡部3313，第二摆臂341与齿轮支架36连接的一端设置有止挡部3413，止挡部3313沿着第一连接部3311的最外侧的端面向外延伸，止挡部3413沿着第二连接部3411的最外侧的端面向外延伸，止挡部3313和止挡部3413与齿轮支架36相抵接；齿轮支架36上设置有与止挡部3313和止挡部3413配合的限位部363和限位部364，其中限位部363设置在齿轮支架36靠近第一摆臂331的一侧，限位部364设置在齿轮支架36靠近第二摆臂341的一侧，且限位部363和限位部364分别位于齿轮支架36的两端，限位部363和限位部364沿着齿轮支架36靠近第一摆臂331和第二摆臂341的一面向靠近第一摆臂331和第二摆臂341的方向延伸，并且，限位部363和限位部364均为弧形壁结构，止挡部3313和止挡部3413也为弧形壁结构，止挡部3313和限位部363配合连接，止挡部3413和限位部364配合连接，当止挡部3313和限位部363接触时，止挡部3313和限位部363可以相互阻挡，此时折叠屏手机不能继续折叠或打开，当止挡部3413和限位部364相互接触时，止挡部3413和限位部364可以相互阻挡，此时折叠屏手机不能继续折叠或打开。
需要说明的是，通过设置止挡部3313、止挡部3413、限位部363和限位部364，可以对第一摆臂331和第二摆臂341的旋转起到限定作用，这样可以使第一摆臂331 和第二摆臂341只能在止挡部3313和限位部363以及止挡部3413和限位部364之间的间隙范围内活动，例如本实施例中，第一摆臂331和第二摆臂341只能向第一显示屏两端靠近的方向弯折。
在一些实施例中，也可以不设置止挡部3313、止挡部3413、限位部363和限位部364，这样第一摆臂331和第二摆臂341可以向内弯折也可以向外弯折。
需要说明的是，止挡部和限位部不构成对本申请技术方案保护范围的限制。在一些示例中，例如，在一些可以向内弯折也可以向外弯折的折叠屏手机中，铰链组件上还可以不设置止挡部和限位部，然后通过其他结构实现第一摆臂和第二摆臂在负90°到正90°的范围内旋转。
在上述实施例中，多个凹槽在主轴机构上的正投影重合，也就是说，凹槽的位置固定，这样可以通过凸起的位置和数量来控制折叠屏手机的悬停角度。例如：不同凸起在主轴机构上的正投影沿着主轴机构的周向间隔分布，一个或者多个凸起对应一个凹槽。
需要说明的是，在上述实施例中，在凸起的数量为多个时，一个凸起可以对应一个凹槽，并且不同凸起对应的凹槽不同，当转动机构旋转到一个预设位置时，一个凸起卡合在其中一个凹槽中，其余凸起抵在弹性组件和转动机构之间；转动机构旋转至另一个预设位置时，另一个凸起卡合在另一个凹槽中，其余凸起抵在弹性组件和转动机构之间。另外，需要说明的是，位于同一预设位置上的不同的凸起在主轴机构上的正投影重合，这样就可以通过一个或多个凸起来控制一个角度的悬停。
另外，在一些实施例中，也可以通过改变凹槽的位置来控制悬停角度，弹片的数量可以为一个，弹片上的第一凸起可以对应多个第一凹槽，第二凸起可以对应多个第二凹槽，转动机构旋转到不同的预设位置时，同第一凸起和第二凸起位于不同的凹槽中。
如图19所示，弹性组件32包括一个弹片32d，弹片32d上的第一凸起323可以对应第一凹槽3312a和第一凹槽3312b，弹片32d上的第二凸起324可以对应第二凹槽3412a和第二凹槽3412b，第一凹槽3312a和第一凹槽3312b可以沿主轴机构31的周向间隔设置，第一凹槽3312a和第一凹槽3312b可以沿主轴机构31的周向间隔设置，这样可以通过一个第一凹槽3312和一个第二凹槽3412来决定一个预设位置。
如图19所示，第一摆臂331与弹片32d接触连接的端面上可以设置第一凹槽3312a和第一凹槽3312b，并且第一凹槽3312a和第一凹槽3312b可以沿主轴机构31的周向间隔分布；第二摆臂341与弹片32d接触连接的端面上可以设置第二凹槽3412a和第二凹槽3412b，并且第二凹槽3412a和第二凹槽3412b可以沿主轴机构31的周向间隔分布，这样在第一摆臂331旋转至第一个预设位置时，第一凸起323可以和第一凹槽3312a卡合，第二凸起324可以和第二凹槽3412a卡合，继续旋转第一摆臂331和第二摆臂341，第一凸起323脱离该处于卡合状态的第一凹槽3312a，第二凸起324脱离该处于卡合状态的第二凹槽3412a；当第一摆臂331和第二摆臂341旋转至第二个预设位置时，第一凸起323可以和第一凹槽3312b卡合，第二凸起324可以和其中另一个第二凹槽3412b卡合。
在本实施例中，通过设置一个弹片以使一个第一凸起323对应两个第一凹槽3312， 一个第二凸起324对应两个第二凹槽3412，这样可以通过一个第一凹槽3312和第二凹槽3412来实现一个角度的悬停。
需要说明的是，上述实施例中的第一凹槽和第二凹槽的数量包括但不限于两个，也可以为三个、四个等，只要是第一凹槽沿着主轴机构的周向间隔分布，且第二凹槽沿主轴机构的周向间隔分布即可。另外，在通过改变凹槽的位置来控制悬停角度的实施例中，可以以图19中所示的结构为最小单元重叠设置多个，此时弹片的数量可以为多个，并且多个弹片上的第一凸起在主轴机构轴向上的正投影重合，且第二凸起在主轴机构轴向上的正投影重合，多个第一凹槽位于多个平面，多个平面上设置的第一凹槽的数量和位置均相同，且位于同一平面的多个第一凹槽沿着第一支撑杆的周向间隔分布；多个第二凹槽位于多个平面，多个平面上设置的第二凹槽的数量和位置均相同，且位于同一平面的多个第二凹槽沿着第二支撑杆的周向间隔分布。
需要说明的是，弹片的数量不构成对本申请技术方案的限制，根据悬停位置的角度和数量可以适当的增加或减少弹片的数量。另外，由于折叠屏手机至少需要能够悬停于完全展开状态和完全折叠状态。
作为解释说明，在使用过程中，可折叠终端一般不需要在任意角度悬停，在某些角度悬停的需要较大，在某些角度不需要悬停。因此通过在铰链组件30a上设计凸起和凹槽，利用凸起和凹槽之间的卡合作用，可以实现铰链组件30a的固定角度悬停，从而减少铰链组件30a中弹性组件32和第一摆臂331以及第二摆臂34之间的磨损。
另外，在上述全部实施例中，将第一摆臂331和第二摆臂341分别与第一支撑杆311和第二支撑杆312固定连接，然后将弹片的第一端321和第二端分别与第一支撑杆311和第二支撑杆312转动连接，从而实现第一摆臂331和第二摆臂341与弹片之间的转动连接。而在一些实施例中，也可以将第一摆臂331和第二摆臂341分别与第一支撑杆311和第二支撑杆312转动连接，然后将弹片的第一端321和第二端分别与第一支撑杆311和第二支撑杆312固定连接，来实现第一摆臂331和第二摆臂341与弹片之间的转动连接。上述两种方式均可以保证在第一摆臂331和第二摆臂341旋转时，只有第一凹槽3312和第二凹槽3412的位置随着第一摆臂331和第二摆臂341转动，第一凸起323和第二凸起324的位置不变，当第一摆臂331和第二摆臂341旋转至预设位置时，使其中一个第一凸起323和一个第一凹槽3312卡合，其中一个第二凸起324和一个第二凹槽3412卡合。
需要说明的是，在一些示例中，也可以将弹片与主轴机构31固定连接，将第一摆臂331和第二摆臂341与主轴机构31转动连接，并且，在第一摆臂331上固定第一齿轮313，第二摆臂341上固定第二齿轮314，在主轴机构31上设置相互啮合的第三齿轮315和第三齿轮316，其中，第一齿轮313和第三齿轮315啮合，第二齿轮314和第三齿轮316啮合，这样通过旋转第一摆臂331也可以是第二摆臂341同步反向转动。
需要说明的是，弹片可以为如图10所示的对称结构，对称轴为主轴机构31的中心轴线，所以同一个弹片上的第一凸起323和第二凸起324以弹片的中心轴线为轴相互对称，因此第一夹角a和第二夹角b的角度相等。在本实施例中，第一夹角a和第二夹角b的角度可以均为30°。这样可以通设置四个第一凸起323和四个第二凸起324来实现在第一摆臂331和第二摆臂341折叠0°、30°、60°和90°。
需要说明的是，本申请实施例中只介绍了铰链组件30a中的部分结构，还有一些连接结构以及紧固结构均为示出，应当理解的是，铰链组件30a的其它结构不够成对本申请技术方案保护范围的限制，只要是铰链组件30a中包括本申请技术方案中的弹性组件32、第一摆臂331、第二摆臂341等结构，均属于本申请技术方案的保护范围。
在本实施例中，通过在弹性组件32上设有凸起327，在转动机构33上设置有凸起327配合的凹槽332，转动机构33旋转至一个预设位置时，一个凸起327卡合在其中一个凹槽332中，其余凸起327抵在弹性组件32和转动机构33之间；转动机构33旋转至另一个预设位置时，另一个凸起327卡合在另一个凹槽332中，其余凸起327抵在弹性组件32和转动机构33之间。可以利用凸起和凹槽配合可以实现铰链组件30a在固定角度悬停，且在悬停状态下凸起卡合在凹槽内，可以保证悬停的稳定性；通过凸起和凹槽的配合实现铰链组件30a的悬停，这样可以避免弹簧、上凸轮和下凸轮的使用，从而可以减少上凸轮和下凸轮之间的磨损，另外减少弹簧的使用可以节约主轴机构31轴向的安装空间，从而简化铰链组件30a的结构，降低成本。
另外，本申请实施例中的弹片为片状结构，尺寸较薄，因此可以减小铰链组件30a的沿主轴机构31轴线上安装空间，进而可以简化铰链组件30a；还可以给铰链组件30a或主轴机构31上的其他部件预留出更多的安装空间。
需要说明的是，在一些示例中，第一凸起323和第二凸起324也可以设置在第一摆臂331和第二摆臂341上，然后将第一凹槽3312和第二凹槽3412设置在弹片上，这样也能实现可折叠屏手机在固定角度悬停。例如，可以将上述技术方案中的第一凸起323和第一凹槽3312的位置互换，将第二凸起324和第二凹槽3412的位置互换，这样也能够解决现有技术中上凸轮和下凸轮之间磨损严重的问题。由于第一凸起323、第二凸起324、第一凹槽3312、第二凹槽3412的位置可以根据具体情况具体设定，因此，第一凸起323、第二凸起324、第一凹槽3312、第二凹槽3412的位置不构成对本申请技术方案保护范围的限制，只要是利用弹片上设置凸起或凹槽的结构，并通过凸起和凹槽之间的卡合来控制铰链组件30a悬停的技术方案均属于本申请技术方案的保护范围，再此不在赘述。
在本申请实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应作广义理解，例如，可以是固定连接，也可以是通过中间媒介间接相连，可以是两个元件内部的连通或者两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请实施例中的具体含义。
在本申请实施例或者暗示所指的装置或者元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。在本申请实施例的描述中，“多个”的含义是两个或两个以上，除非是另有精确具体地规定。
