技术领域
本申请属于通信设备技术领域，具体涉及一种铰链机构和电子设备。
背景技术
随着技术的发展，可变形的显示产品逐渐成熟，折叠屏手机等电子设备蓬勃发展。为了使折叠屏电子设备具有“半展开”状态悬停的能力，目前的折叠屏手机中，通常在铰链机构中内置弹簧，以为转动部件提供扭矩，使折叠屏电子设备中用以支撑显示屏的部件之间能够保持在呈120°等特定角度的状态，进而使显示屏悬停于“半展开”状态。但是，在上述技术方案中，需要使弹簧沿转动方向的轴向布设，这导致弹簧占用的空间相对较大，对电子设备内的空间利用效率会产生较大的不利影响。
发明内容
本申请实施例的目的是提供一种铰链机构和电子设备，以解决目前折叠式电子设备为实现悬停目的设置的弹簧需沿转动轴向布设，对电子设备的空间利用效率会产生不利影响的问题。

所述摆臂套设于所述转轴，所述转轴与所述安装座转动连接，所述摆臂设有挤压部，所述顶持件的一端与所述挤压部抵接，所述顶持件的另一端与所述配合部抵接；
在所述转轴和所述摆臂同步转动的情况下，所述挤压部挤压所述顶持件，以推动所述配合部驱动所述旋转座转动预紧所述第一弹性复位件，且所述旋转座驱动所述限位件压紧所述转轴，以限制所述转轴的转动。
第二方面，本申请实施例公开一种电子设备，其包括多个屏幕支撑部和上述铰链机构，任一相邻的两个所述屏幕支撑部均与所述铰链机构中的所述摆臂连接。
本申请实施例公开一种铰链机构，该铰链机构可以被应用在电子设备中，以使电子设备中相邻的两个屏幕支撑部之间具备相对转动的能力，进而使电子设备能够在折叠状态和展开状态之间切换。铰链机构中，摆臂朝向安装座的一侧设有挤压部，挤压部用以与顶持件的一端抵接，从而在摆臂相对安装座旋转的过程中，可以通过挤压部驱动顶持件沿摆臂的旋转轴向作直线运动。同时，顶持件的另一端与旋转座上的配合部抵接，以在顶持件沿旋转轴向向远离摆臂的方向运动时，能够通过配合部挤压旋转座相对安装座沿围绕旋转轴向的方向作旋转运动；并且，在旋转座旋转的过程中，可以预紧第一弹性复位件，使第一弹性复位件储存弹性势能，且旋转座还可以驱动限位件动作，使一部分连接于安装座，另一部分相对安装座和旋转座均活动的限位件能够抱紧转轴，以限制转轴的转动。
基于上述技术方案，在铰链机构的工作过程中，当顶持件与挤压部中最靠近安装座的端点(或端面)配合时，即可使顶持件与挤压部形成较为稳定的配合关系，进而使铰链机构的各部件均保持相对静止，使铰链机构中在垂直于前述旋转轴向的方向上相邻的两个摆臂之间的夹角可以被定位在某些特 定的角度，使铰链机构具备悬停能力，从而使利用该铰链机构形成的电子设备的显示屏可以呈现特定的展开角度。
同时，在上述铰链机构中，由于第一弹性复位件的作用方向为围绕旋转轴向的方向，从而可以利用围绕旋转轴向的方向布设第一弹性复位件，这使得第一弹性件在旋转轴向所在的方向上占用的空间相对较小，仅为第一弹性复位件的宽度(或直径)；并且，限位件位于转轴和旋转座之间，这使得限位件也不会额外占用转轴的轴向所在的方向上的空间，因此，本申请实施例公开的铰链机构可以提升电子设备的空间利用效率。

如图1-图3所示，本申请实施例公开的铰链机构包括安装座110、摆臂210、转轴300、抱紧组件400和顶持件500。其中，摆臂210用于与电子设备中的屏幕支撑部连接，以在屏幕支撑部转动时带动摆臂210一并转动。摆臂210套设于转轴300，且相互配合的摆臂210和转轴300同步转动，进而在摆臂210和转轴300中的一者转动的过程中，可以带动摆臂210和转轴300中的另一者一并转动。并且，在摆臂210上的挤压部220的驱动作用下，可以使顶持件500沿转轴300的轴向运动，在顶持件500的作用下，能够驱动抱紧组件400中的旋转座410沿转轴300的周向旋转，且使第一弹性复位件430被压缩(或被拉伸)，当摆臂210的挤压部220上靠近安装座110的端点 (或端面，端点为挤压部220中最靠近安装座110的位置)与顶持件500配合时，第一弹性复位件430的弹性势能达到最大。
另外，为了保证挤压部220的端点与顶持件500之间能够形成较为稳定的配合关系，可以通过在挤压部220的端点(或端面)处设置定位凹陷等结构，或者，在顶持件500朝向挤压部220的一端设置定位凹陷等方式，使顶持件500运动至挤压部220的端点处时，能够在不受外力作用的情况下保持于前述状态；相应地，在铰链机构受到外力作用时，则可以打破前述状态，使顶持件500越过挤压部220的端点，进而在第一弹性复位件430的作用下，使铰链机构中的旋转盘反向转动以复位，且使摆臂210能够带动转轴300继续相对安装座110转动。
另外，还可以通过增大挤压部220上靠近安装座110的端点与顶持件500之间的摩擦力的大小的方式，使顶持件500在沿挤压部220运动至挤压部220的前述端点处时，利用摩擦力限制顶持件500继续运动，且利用摩擦力克服第一弹性复位件430被挤压(或被拉伸)而具备的弹性作用力。
详细地说，抱紧组件400包括旋转座410、配合部421、第一弹性复位件430和限位件，旋转座410可以采用硬质材料形成，旋转座410可以为立方体等块状结构件，且旋转座410可以设置在转轴300的一侧，或者，旋转座410还可以为环状结构件，在这种情况下，旋转座410可以套设在转轴300之外，且旋转座410与安装座110在转轴300的周向上转动配合，以保证旋转座410可以被驱动，以预紧第一弹性复位件430，且使限位件能够压紧转轴300，以限制转轴300的转动。
配合部421固设于旋转座410，具体来说，配合部421用以与上述顶持件500配合，以在顶持件500沿转轴300的轴向运动的情况下，通过配合部421驱动旋转座410相对安装座110旋转。配合部421具体可以为柱状凸起，以与顶持件500接触配合。旋转座410和安装座110可以通过额外设置中心轴的方式，形成转动配合关系，或者，通过使安装座110和旋转座410均套 设在转轴300之外，且利用限位结构使安装座110与旋转座410能够相对转动。
第一弹性复位件430可以由弹性材料形成，以保证第一弹性复位件430具备弹性能力，且在受到外力时被压缩，撤去外力时能够恢复自身形变，产生复位作用。在本申请的另一实施例中，第一弹性复位件430可以为弹簧，以保证第一弹性复位件430具有相对较大的弹性形变量和弹性势能，提升第一弹性复位件430的弹性复位能力。
并且，第一弹性复位件430弹性连接于旋转座410和安装座110之间，具体来说，在旋转座410为块状结构件的情况下，可以在安装座110上设置挡板，且使第一弹性复位件430设置于挡板和旋转座410之间。在挡板位于旋转座410沿旋转方向的下游时，可以使第一弹性复位件430抵接于挡板和旋转之间，以在旋转座410相对安装座110转动时，能够挤压第一弹性复位件430；在挡板位于旋转座410沿旋转方向的上游时，则可以使第一弹性复位件430的相背两端分别与挡板和旋转座410固定连接，以在旋转座410相对安装座110转动使，能够拉伸第一弹性复位件430。当然，还可以在旋转座410朝向安装座110的一侧设置凹槽，且使前述挡板和第一弹性复位件430均设置于前述凹槽内，亦可以保证第一弹性复位件430能够弹性连接于旋转座410和安装座110之间。而在旋转座410为环状结构的情况下，则可以使第一弹性复位件430与销轴460一并设置在限位槽411内，且根据第一弹性复位件430的具体设置位置，确定第一弹性复位件430的具体装配方式，考虑文本简洁，此处不再重复。
在旋转座410和安装座110之间弹性设置有第一弹性复位件430的情况下，可以利用第一弹性复位件430限制旋转座410和安装座110在转轴300的周向上相对转动。当然，在外力作用下，旋转座410和安装座110亦可以相对转动，且使第一弹性复位件430预紧，也即，使第一弹性复位件430被拉伸或被压缩以储存弹性势能。并且，在外力撤去之后，第一弹性复位件430 可以在自身弹性势能的作用下恢复形变，且驱动旋转座410和安装座110复位。
限位件设置于转轴300的外侧，且旋转座410可转动地设置于限位件的外侧，也即，限位件位于转轴300和旋转座410之间，旋转座410用以为限位件的动作提供驱动作用。在安装限位件的过程中，限位件的一部分连接与安装座110，限位件的另一部分相对安装座110和旋转座410均活动，以利用限位件为转轴300提供抱紧作用。
可选地，限位件具体为单独的部件，例如，其可以为块状结构件，且使限位件具备一定的变形能力，在此情况下，限位件的相背两端可以分别连接于旋转座410的内侧和安装座110，从而在转轴300转动，且通过顶持件500带动旋转座410相对安装座110转动的过程中，使得旋转座410能够通过挤压限位件的方式，使限位件变形且挤压转轴300，提升限制转轴300继续转动的作用。当然，在本申请的其他实施例中，限位件亦可以为组合式结构，即限位件可以包括多个部分，多个部分均位于旋转座410和转轴300之间，且可以使限位件中的一部分与旋转座410连接，使限位件中的其他一部分与安装座110连接。
在组装铰链机构的过程中，沿转轴300的轴向，安装座110设置于摆臂210与旋转座410之间，进而保证安装座110可以为用以与摆臂210和旋转座410均配合的顶持件500提供安装作用。具体地，安装座110可以采用金属或塑料等硬质材料形成，安装座110的实际形状可以根据铰链机构和/或电子设备内的剩余空间等情况确定，此处不作限定。在本申请实施例公开的铰链机构中，安装座110实际可以被看作是参考系，也即，可以认为安装座110为铰链机构中相对静止的部件，铰链机构中的摆臂210、转轴300、抱紧组件400和顶持件500等其他部件可以相对安装座110相对转动或相对移动。
为了保证安装座110可以作为铰链机构中的其他部件的参考系，可以使安装座110与相邻的两个转轴300直接连接或间接连接，如可以使两个转轴 300分别穿设于两个安装座110上，且使两个转轴300能够相对对应的安装座110转动，通过使两个安装座110固定连接，即可利用安装座110保证两个转轴300之间的间距始终保持不变。同时，由于摆臂210和抱紧组件400均套设于转轴300，继而使得安装座110亦可以为摆臂210和抱紧组件400提供定位作用。相应地，通过使顶持件500安装在安装座110上，使得顶持件500的运动范围亦可以被安装座110所限制，保证前述部件连为一体，形成一整体式结构件。或者，铰链机构中还可以包括基座900，基座900套设在相邻的两个转轴300之间，在这种情况下，可以使安装座110与基座900形成固定连接关系，这亦可以保证安装座110可以作为铰链机构中其他部件的参考系。
摆臂210为铰链机构用于与电子设备的屏幕支撑部直接连接的部件，进而在相邻的两个屏幕支撑部相对转动的过程中，可以一并带动与两个屏幕支撑部对应连接的两个摆臂210相对转动。如上所述，安装座110可以作为铰链机构中其他部件的参考系，为此，可以通过使摆臂210套设在转轴300上的方式，保证摆臂210与安装座110能够在转轴300的周向上转动配合。
同时，摆臂210与转轴300在转轴300的周向上相对固定，从而在摆臂210转动的过程中，可以带动转轴300同步转动。具体地，可以使摆臂210和转轴300采用一体成型的方式形成，保证二者可以同步转动；或者，还可以通过键连接的方式，使摆臂210与转轴300在转轴300的周向上相对固定。
另外，在摆臂210相对安装座110转动时，为了保证摆臂210可以通过顶持件500驱动旋转座410转动，还需为摆臂210和旋转座410分别设置与顶持件500相互配合的机构。对于摆臂210而言，具体可以为上述挤压部220，摆臂210设有挤压部220，且使挤压部220设有驱动斜面221，驱动斜面221具体可以为倾斜的平面，亦可以为倾斜的弧形面，且使驱动斜面221的起始端和末尾端与安装座110在转轴300的轴向上的间距不同，即可在顶持件500与驱动斜面221上的不同位置配合时，使顶持件500相对安装座110在转轴 300的轴向上的相对位置发生变化，进而在摆臂210相对安装座110转动时，可以利用驱动斜面221驱动顶持件500沿转轴300的轴向相对安装座110运动。
对于旋转座410而言，旋转座410设有配合部421，利用配合部421使得旋转座410可以与顶持件500配合。具体来说，顶持件500沿转轴300的轴向活动安装于安装座110，且顶持件500可以设有驱动面521，以使顶持件500利用驱动面521与配合部421配合。相似地，驱动面521亦为倾斜面，倾斜面相对转轴300的轴向倾斜，以保证顶持件500在相对安装座110沿转轴300的轴向运动的过程中，可以通过驱动面521与配合部421配合，且驱动旋转座410旋转。
基于上述内容，使得顶持件500的一端能够与挤压部220抵接，且使顶持件500的另一端能够与配合部421抵接，进而在转轴300和摆臂210同步转动的情况下，使得挤压部220能够挤压顶持件500，在顶持件500作为中间媒介的条件下，能够推动配合部421驱动旋转座410转动，预紧第一弹性复位件430，使第一弹性复位件430储存弹性势能，同时，在旋转座410转动的情况下，使得旋转座410能够驱动限位件压紧转轴300，以限制转轴300的转动。
另外，为了保证应用上述铰链机构的电子设备在折叠或展开过程中可以持续翻转，可以使挤压部220的驱动斜面221为往复式结构，也即，挤压部220相对摆臂210凸出设置，以挤压部220中最靠近安装座110的端点为界，挤压部220的表面中位于挤压部220的端点一侧的面为前述驱动斜面221，位于挤压部220的端点另一侧的面为复位面，在顶持部越过前述端点之后，顶持部即可在第一弹性复位件430的作用下挤压于复位面，且使限位件逐渐松开转轴300，保证电子设备可以切换至折叠状态(或切换至展平状态)。
如上所述，可以利用在挤压部220的端点处设置向远离安装座110的方 向延伸的定位凹陷的方式，使顶持件500的一端伸入至挤压部220的定位凹陷内实现定位顶持件500的目的。或者，亦可以利用在顶持件500的另一端设置定位凹陷的方式，使顶持件500在驱动配合部421运动至对应的位置处之后，能够使配合部421伸入顶持件500的定位凹陷内，实现定位顶持件500的目的。再比如，还可以利用增大挤压部220的端点与顶持件500之间的摩擦力的方式，保证在摆臂210通过顶持件500驱动旋转座410转动，且挤压第一弹性复位件430的过程中，第一弹性复位件430能够稳定地处于被挤压状态，进而在第一弹性复位件430和限位件的共同作用下，限制旋转座410继续转动，且可以限制旋转座410自动复位(即旋转座410自动向反方向转动以复位)，使铰链机构中的两个摆臂210之间的角度可以保持于特定值，进而使利用该铰链机构形成的电子设备具备悬停功能，使电子设备的显示屏可以保持在非展开状态和非折叠状态之外的“半展开”状态。
而在需要使旋转座410向反方向旋转且复位的情况下，则可以通过向摆臂210继续施加作用力，使顶持件500能够自挤压部220上的定位凹陷内移出，和/或使配合部421自顶持件500的定位凹陷内移出，和/或克服顶持件500与挤压部220之间的摩擦力，进而使顶持件500能够越过挤压部220中最靠近安装座110的端点(或端面)，使得顶持件500不再向旋转座410提供转动驱动力。同时，在第一弹性复位件430不再受顶持件500的驱动作用的情况下，使得第一弹性复位件430可以在自身弹性势能的作用下恢复形变，且驱动旋转座410相对安装座110反向转动以复位，相应地，转轴300亦不再受限位件所限制，而恢复相对安装座110转动的能力，从而使转轴300和摆臂210能够继续转动，且使电子设备切换至折叠状态或展平状态。
本申请实施例公开一种铰链机构，该铰链机构可以被应用在电子设备中，以使电子设备中相邻的两个屏幕支撑部之间具备相对转动的能力，进而使电子设备能够在折叠状态和展开状态之间切换。铰链机构中，摆臂210朝向安装座110的一侧设有挤压部220，挤压部220用以与顶持件500的一端抵接， 从而在摆臂210相对安装座110旋转的过程中，可以通过挤压部220驱动顶持件500沿摆臂210的旋转轴300向作直线运动。同时，顶持件500的另一端与旋转座410上的配合部421抵接，以在顶持件500沿旋转轴300向向远离摆臂210的方向运动时，能够通过配合部421挤压旋转座410相对安装座110沿围绕旋转轴300向的方向作旋转运动；并且，在旋转座410旋转的过程中，可以预紧第一弹性复位件430，使第一弹性复位件430储存弹性势能，且旋转座410还可以驱动限位件动作，使一部分连接于安装座110，另一部分相对安装座110和旋转座410均活动的限位件能够抱紧转轴300，以限制转轴300的转动。
基于上述技术方案，在铰链机构的工作过程中，当顶持件500与挤压部220中最靠近安装座110的端点(或端面)配合时，即可使顶持件500与挤压部220形成较为稳定的配合关系，进而使铰链机构的各部件均保持相对静止，使铰链机构中在垂直于前述旋转轴300向的方向上相邻的两个摆臂210之间的夹角可以被定位在某些特定的角度，使铰链机构具备悬停能力，从而使利用该铰链机构形成的电子设备的显示屏可以呈现特定的展开角度。
同时，在上述铰链机构中，由于第一弹性复位件430的作用方向为围绕旋转轴300向的方向，从而可以利用围绕旋转轴300向的方向布设第一弹性复位件430，这使得第一弹性件在旋转轴300向所在的方向上占用的空间相对较小，仅为第一弹性复位件430的宽度(或直径)；并且，限位件位于转轴300和旋转座410之间，这使得限位件也不会额外占用转轴300的轴向所在的方向上的空间，因此，本申请实施例公开的铰链机构可以提升电子设备的空间利用效率。
如上所述，顶持件500的一端用以与挤压部220抵接，顶持件500的另一端用以与配合部421抵接，更具体地说，顶持件500可以包括顶杆510、驱动凸块520和连接部530，顶杆510即为顶持件500中用以与挤压部220抵接配合的部件，驱动凸块520为顶持件500中用以与配合部421抵接配合 的部件，连接部530则为用以使顶杆510和驱动凸块520连为一体的部件，也即，顶杆510通过连接部530与驱动凸块520固定连接。可选地，顶杆510、驱动凸块520和连接部530三者可以采用一体成型的方式形成，以提升顶持件500的整体结构可靠性。当然，为了便于加工，顶杆510和驱动凸块520亦可以分体成型。
另外，如上所述，顶持件500与配合部421抵接的一端可以设有驱动面521，在顶持件500包括上述驱动凸块520的情况下，前述驱动面521设置于驱动凸块520。驱动面521具体可以为倾斜的平面，在本申请的一个具体实施例中，驱动面521为倾斜的弧形面，这可以减小驱动面521与配合部421抵接时的接触面积大小，进而降低二者之间的摩擦力，降低驱动面521的驱动难度。
相似地，顶持件500的一端还与挤压部220抵接配合，可选地，顶持件500与挤压部220配合的一端设有被挤压面，在顶持件500包括顶杆510的情况下，被挤压面设置于顶杆510上，被挤压面用以与挤压部220抵接。为了减小被挤压面与挤压部220之间的摩擦力，被挤压面可以为弧形面或球形面，以减小被挤压面与挤压部220之间的接触面积，降低顶持件500的被驱动难度。
顶持件500安装在安装座110上，在顶持件500包括顶杆510、驱动凸块520和连接部530的情况下，安装座110可以设有容纳槽111和连通槽112，容纳槽111与连通槽112连通，且容纳槽111连通于安装座110朝向挤压部220的一侧表面，连通槽112连通于安装座110的侧面。具体地，容纳槽111和连通槽112均可以在安装座110成型之后通过钻加工或切削加工等方式形成于安装座110上，并且，为了保证顶杆510能够与挤压部220相配合，为了便于顶持件500与安装座110之间组装工作的进行，可以使连通槽112延伸至安装座110朝向挤压部220的一侧表面，从而可以自安装座110朝向挤压部220的一侧表面将顶杆510安装至容纳槽111内，且将连接部530安装 至连通槽112内。
在采用上述技术方案的情况下，顶杆510可以安装在容纳槽111内，且使顶杆510能够在容纳槽111内沿转轴300的轴向活动，从而利用容纳槽111为顶杆510提供导向和限位作用，使顶杆510的运动过程更为稳定。连接部530安装于连通槽112内，且使驱动凸块520位于安装座110的外侧，降低驱动凸块520与配合部421的配合难度，且在连通槽112的作用下，使得连接部530能够将位于安装座110内部的顶杆510和位于安装座110一侧的驱动凸块520连接为一体，使顶杆510能够带动驱动凸块520沿转轴300的轴向运动。
并且，在上述技术方案中，可以利用配合部421为顶持件500提供支撑作用，使顶持件500的顶杆510与容纳槽111的槽底相互间隔，且在顶杆510被挤压部220挤压时，通过连接部530向驱动凸块520施加驱动力，使驱动凸块520随顶杆510一并沿转轴300的轴向运动，在此过程中，驱动凸块520可以向配合部421施加作用力，以利用配合部421驱动旋转座410相对安装座110旋转。
对应地，在顶杆510不再受挤压部220所挤压时，第一弹性复位件430恢复自身弹性形变，使得第一弹性复位件430能够驱动旋转座410反向转动以复位，在此过程中，配合部421随旋转座410反向转动，进而使得配合部421可以推动驱动凸块520沿转轴300的轴向向靠近摆臂210的方向运动，且使顶持件500的顶杆510能够始终与挤压部220保持抵接关系。
在本申请的另一实施例中，为了进一步保证顶持件500能够始终与挤压部220形成有抵持配合关系，顶持件500还可以包括第二弹性复位件540，第二弹性复位件540弹性设置与顶杆510和安装座110之间，且在挤压部220挤压顶持件500远离摆臂210的情况下，预紧第二弹性复位件540，从而在挤压部220最靠近安装座110的端点或端面与顶持件500配合时，使第二弹性复位件540的弹性势能达到最大，当摆臂210受外力作用，且打破顶持件 500和挤压部220之间的配合关系之后，使得第二弹性复位件540能够驱动顶杆510向靠近摆臂210的方向运动，且使顶杆510始终抵持在挤压部220的表面，保证顶持件500的复位可靠性，且减小第一弹性复位件430的负载，保证旋转座410亦可以在第一弹性复位件430的作用下可靠的复位。
更具体地，在安装座110设有容纳槽111的情况下，可以使第二弹性复位件540设置于容纳槽111内，且使顶杆510背离挤压部220的一端与第二弹性复位件540抵接，从而利用容纳槽111为第二弹性复位件540提供限位和导向作用，提升第二弹性复位件540的可靠性和稳定性。
如上所述，限位件的一部分可以连接在安装座110上，且限位件的另一部分可以相对安装座110和旋转座410均活动，且限位座可以为单体结构件，或者限位件可以为多个部分形成的结构组件。在本申请的一个具体实施例中，限位件包括摩擦块440、连接件450和销轴460，其中，摩擦块440为限位件中用以与转轴300配合的部件，其可以为转轴300提供抱紧作用，以限制转轴300的转动；连接件450为在旋转座410和摩擦块440之间传递驱动作用的部件，以在旋转座410旋转的情况下，将旋转座410的驱动作用传递至摩擦块440上，使摩擦块440相对转轴300运动；销轴460为连接摩擦块440和安装座110的部件，以使摩擦块440能够与安装座110形成转动配合关系，进而在摩擦块440受到连接件450的驱动作用时，能够以销轴460为轴相对安装座110转动，且向靠近转轴300的方向运动，以抱紧转轴300，且限制转轴300的转动。
具体来说，摩擦块440可以采用橡胶等摩擦性能相对较好的材料形成，摩擦块440可以为块状结构，更具体地，摩擦块440可以为弧形结构件，从而在利用摩擦块440与转轴300配合时，使摩擦块440与转轴300之间的贴合面积相对更大，提升摩擦块440对转轴300提供的抱紧效果。摩擦块440的一端可以通过销轴460与安装座110转动连接，从而使摩擦块440能够以销轴460为轴相对安装座110转动。
当然，在旋转座410被顶持件500所驱动而转动时，为了保证摩擦块440能够向靠近转轴300的方向运动，可以使连接件450的一端与旋转座410转动连接，且使连接件450的另一端转动连接于摩擦块440的相背两端之间，以在旋转座410转动的情况下，能够通过连接件450向摩擦块440的中部施加驱动作用力，以驱动摩擦块440以销轴460为轴相对安装座110转动，且压紧转轴300，从而限制转轴300的转动。具体地，连接件450可以为杆状结构，为了提升连接件450的驱动稳定性，可以使连接件450为弧形片状结构，以在转轴300的轴向上为摩擦块440提供更为均匀的驱动作用。并且，为了使连接件450的相背两端与旋转座410和摩擦块440之间所形成的转动配合关系更为稳定，可以在旋转座410和摩擦块440上对应的位置处设置槽状限位结构，且在连接件450的相背两端设置圆柱状结构作为“轴”，使连接件450的相背两端的“轴”与前述槽状限位结构对应地转动配合，提升连接件450的动作稳定性。
为了进一步提升转轴300的被抱紧效果，可选地，限位件的数量为多个，多个限位件沿转轴300的周向相互间隔，以防止限位件在抱紧转轴300的过程中存在相互妨碍的情况；同时，使多个限位件围合转轴300设置，从而自转轴300的不同方位处为转轴300提供抱紧作用，使转轴300周向上的各处的被限制效果相同或相似，达到提升转轴300的被抱紧效果的目的。具体地，多个限位件的形状和尺寸可以对应相同，以降低多个限位件的安装难度，且提升多个限位件对转轴300的限制作用。更具体地，各限位件均可以包括上述摩擦块440、连接件450和销轴460，以使各限位件均具有相对较好的限位作用。
如上所述，配合部421可以为柱状凸起，且使顶持件500与配合部421抵接配合，使二者通过滑动摩擦的方式，实现顶持件500通过配合部421驱动旋转座410相对安装座110转动的目的。在本申请的另一实施例中，为了进一步降低旋转座410的被驱动难度，配合部421设有滚轮422，滚轮422 滚动地安装于配合部421，且滚轮422与顶持件500滚动配合，从而使顶持件500利用与滚轮422之间的滚动摩擦配合关系，实现驱动旋转座410转动的目的，这可以减小顶持件500所受的摩擦力大小，从而提升旋转座410的转动顺畅性。更具体地，在顶持件500包括上述驱动凸块520的情况下，可以使驱动凸块520与滚轮422滚动配合，且通过滚轮422驱动旋转座410相对安装座110转动。
如上所述，第一弹性复位件430可以通过多种方式弹性设置于安装座110和旋转座410之间，一种具体的实施例是，旋转座410上设有沿转轴300的周向延伸的限位槽411，且为了保证第一弹性复位件430可以为旋转座410提供弹性复位作用，旋转座410可以通过固定于安装座110的限位轴470与安装座110在转轴300的周向上形成限位配合关系，且使第一弹性复位件430弹性设置于限位轴470和限位槽411的端壁之间，进而利用限位槽411为第一弹性复位件430提供安装、导向和限位作用，一方面进一步减小铰链机构中部件的占用空间，提升铰链机构内部的空间利用率，另一方面，还可以提升第一弹性复位件430的动作稳定性。
具体地，可以使限位槽411在旋转盘上沿转轴300的周向延伸，从而使限位槽411的形状适应于旋转座410的动作轨迹，提升限位槽411的导向和限位作用。限位槽411的延伸长度与第一弹性复位件430的自然长度相关，在旋转座410处于初始状态，也即挤压部220尚未向顶持件500施加挤压作用力，且挤压配合部421的情况下，可以使限位轴470位于限位槽411的一端端壁处，且使第一弹性复位件430的相背两端分别抵接于限位槽411的另一端端壁和限位轴470之间，从而在挤压部220通过顶持件500驱动配合部421带动旋转座410旋转的过程中，由于限位轴470与安装座110相对固定，随着旋转座410的持续转动，使得第一弹性复位件430可以被持续挤压，且在顶持部运动至挤压部220的端点处的情况下，即可使第一弹性复位件430的弹性势能达到最大，相应地，在顶持部越过挤压部220的端点之后，第一 弹性复位件430即可在自身弹性作用下恢复形变，且带动旋转座410反向转动以复位。
为了进一步提升旋转座410的动作稳定性和可靠性，可选地，限位槽411、限位轴470和第一弹性复位件430的数量均为多个，且多个限位槽411沿转轴300的周向间隔设置于旋转座410，多个限位槽411、多个限位轴470和多个第一弹性复位件430一一对应配合，从而利用分散地分布于旋转座410上的多个第一弹性复位件430为旋转座410提供更为稳定可靠地复位作用、更具体地，可以使多个限位槽411的形状和尺寸对应相同，以降低第一弹性复位件430的安装难度，且可以使多个限位槽411沿转轴300的周向均匀设置，以为旋转盘提供更为均匀的复位作用力。
基于上述实施例，在限位件包括摩擦块440的情况下，可以使限位槽411的数量与摩擦块440的数量相等，且使多个限位槽411与多个摩擦块440一一对应，以进一步提升摩擦块440与转轴300之间的限位均匀性和可靠性。
如上所述，安装座110可以通过与基座900固定的方式，使安装座110不会随转轴300旋转，由于铰链机构用以连接相邻的两个屏幕支撑部，且两个屏幕支撑部均需具备转动能力，为此，屏幕支撑部与转轴300的数量相对对应，也即，连接于相邻的两个屏幕支撑部之间的铰链机构中可以包括两个转轴300，对应地，安装座110的数量亦可以为两个，且两个安装座110与两个转轴300一一对应设置。
更详细地说，安装座110、摆臂210、转轴300、抱紧组件400和顶持件500均相互对应，几者可以共同组成悬停组件，以为屏幕支撑部提供悬停作用。并且，由于铰链机构包括两个转轴300，为此，铰链机构可以包括至少两组悬停组件，相邻的悬停组件中的转轴300沿垂直于转轴300的轴向的方向分布，且相邻的悬停组件分别用以为相邻的两个屏幕支撑部提供悬停作用。可选地，在转轴300的轴向上，可以使转轴300的尺寸与屏幕支撑部的尺寸相同或相近，在这种情况下，可以在同一转轴300上设置多个摆臂210、抱 紧组件400和顶持件500等，且使多个摆臂210沿转轴300的轴向间隔分布，多个摆臂210均与同一屏幕支撑部连接；或者，还可以设置多个沿转轴300的轴向间隔分布的转轴300，且使多个转轴300一一对应地配设有摆臂210、抱紧组件400和顶持件500等，从而利用多个悬停组件与同一屏幕支撑部对应连接，以提升屏幕支撑部的动作稳定性。
基于上述实施例，可以使同一铰链机构中相邻的两个安装座110通过桥接座120固定连接，且前述两个安装座110分别与两个转轴300一一对应配合。在此情况下，两个安装座110之间可以形成固定连接关系，且在转轴300的转动过程中，亦不会使安装座110随转轴300转动。
如上所述，通过铰链机构连接的相邻的两个屏幕支撑部均具备相对安装座110转动的能力，为此，本申请实施例公开的铰链机构还可以包括同步机构，同步机构可以包括第一齿轮和第二齿轮，且第一齿轮和第二齿轮可以分别安装在铰链机构中沿垂直于转轴300的轴向的方向相邻的两个转轴300上，第一齿轮和第二齿轮相互啮合，且使二者分别随对应的转轴300转动，在此情况下，即可使与相邻的两个屏幕支撑部分别连接的两个摆臂210能够形成同步转动的配合关系，进而在某一屏幕支撑部相对安装座110旋转的情况下，即可通过同步机构带动另一屏幕支撑部相对安装座110旋转，使相邻的两个屏幕支撑部形成同步转动关系，保证柔性屏上任一位置的被弯折角度均相对较小，提升柔性屏的使用寿命。
或者，还可以在与相邻的屏幕支撑部分别连接的摆臂210上形成轮齿，且使前述相邻的摆臂210中的一者的轮齿通过第一齿轮和第二齿轮与另一者上的轮齿形成同步啮合关系，这亦可以使沿垂直于转轴300的轴向的方向相邻的两个摆臂210形成同步关系，且可以使第一齿轮和第二齿轮不会额外占用转轴300的轴向空间，提升铰链机构中部件的安装紧凑性。相应地，为了保证第一齿轮和第二齿轮的动作稳定性，在铰链机构包括上述桥接座120的情况下，可以在桥接座120上设置两个轴孔，且使第一齿轮和第二齿轮的轮 轴分别转动安装至两个轴孔内，提升第一齿轮和第二齿轮的动作稳定性。
基于上述任一实施例公开的铰链机构，本申请实施例还公开一种电子设备，电子设备包括多个屏幕支撑部和上述任一铰链机构。在组装电子设备的过程中，任意相邻的两个屏幕支撑部均与铰链机构中的摆臂210连接，从而使相邻的两个屏幕支撑部能够通过铰链机构形成转动配合关系。
