具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1为本公开的一些实施例提供的一种铰链的结构示意图。如图1和图2所示，一种铰链10，包括至少两个关节101，所述至少两个关节101顺次连接；
每个关节101均包括关节基体100，设置于所述关节基体100的第一端部的转动结构200，以及设置于所述关节基体100的第二端部的支撑部300，所述第一端部和所述第二端部相对设置；
任意相邻两关节的转动结构200相套接，相邻两关节的转动结构200相对转动，以实现相邻两关节开合；
所述铰链10还包括柔性连接件400，每个关节的支撑部300均与所述柔性连接件400连接，所述柔性连接件400能够随关节的打开而伸展，且随关节的合拢而收拢。
本公开的一些实施例提供的铰链10，包括顺次连接的至少两个关节101，该至少两个关节的结构可以相同。每个关节的关节基体100为关节的主要部件，关节基体100包括相对设置的第一端部和第二端部，将关节基体100与所贴合部件贴合的一端作为第一端部，将远离所述第一端部的一端作为第二端部。
关节基体100的第一端部设置有转动结构200，用于实现关节之间的相对转动。关节基体100的第二端部还设置有支撑部300，支撑部300与柔性连接件400连接，由于支撑和限制关节之间的相对转动。至少两个关节中任意相邻两关节的转动结构200相套接，以及相邻两关节的支撑部300均带动 柔性连接件400运动，且受柔性连接件400的限制，即可实现相邻关节之间的开合。铰链10中的至少两个关节的打开和合拢，即可实现铰链10对所贴合部件的支撑作用。
在一些具体实施方式中，如图1所示，铰链10也可以由至少三个关节101顺次连接形成。将位于铰链10两端的关节101分别定义为首关节104和尾关节105，位于首关节104与尾关节105之间的关节101可以定义为中关节106，铰链10可以包括首关节104、尾关节105和至少一个中关节106。至少一个中关节106的结构可以完全相同，首关节104和尾关节105除了包括与相邻关节101相匹配的转动结构200和支撑部300外，还可以包括用于与所贴合部件连接的连接部。
将任意相邻两关节的转动结构200相套接，以使得相邻两关节的转动结构200相对转动。这样，相邻关节随转动结构200相对转动时，相邻两关节的第二端部设置的支撑部300以及所连接的柔性连接件400也能够相对往复运动，以实现相邻两关节的打开和合拢。由于关节的第二端部设置的支撑部300还连接有柔性连接件400，所述柔性连接件400可以限制相邻关节之间的打开程度。当相邻两关节的开度达到预设值时，柔性连接件400限制相邻两两关节的过度打开。
本实施例提供的铰链，通过将任意相邻两关节的转动结构相套接，以使得相邻两关节的转动结构相对转动，并且通过限位结构将相邻两关节的开度限制在预设范围内。这样，形成铰链的关节结构相同，便于加工和装配。通过增减关节的数量即可改变铰链的长度和弯折程度，优化了铰链的装配方案。
在上述实施例的基础上，如图1至图4所示，所述转动结构200可以包括转动轴210以及弧形转动轴瓦220，所述转动轴210与所述关节基体100之间设置有弧形空隙230；
任意相邻两关节101中，第一关节的转动轴瓦220插入第二关节的弧形空隙230内，以与第二关节的转动轴210相套接，第二关节的转动轴瓦220能够绕第一关节的转动轴210相对转动。
本实施例提供的铰链10在装配时，可以将相邻两关节组合装配。具体的，将任意相邻两关节，可以分别定义为第一关节和第二关节。这里，只是针对 任意相邻的两个关节进行描述，不具体限定到铰链10中的某个关节。例如，某关节在与其前一关节相配合装配时，该关节可以被定义为第二关节，该关节在与其后一关节相配合装配时，该关节又可以被定义为第一关节。
本实施例提供的铰链10中，每个关节101的转动结构200均包括转动轴210以及弧形转动轴瓦220，关节101的转动轴210与关节基体100之间还设置有能够容纳转动轴瓦220的弧形空隙230。
相邻两关节101装配时，将第一关节的转动轴瓦220插入到第二关节的弧形空隙230内，以使得第一关节的转动轴瓦220与第二关节的转动轴210相套接，则该第二关节的转动轴瓦220就可以与第一关节的转动轴210相对转动。这样，每个关节101的转动轴瓦220均可以绕与其相邻的关节101的转动轴210相对转动，且每个关节101的转动轴瓦220均可以绕与其相邻的关节101的转动轴210相对转动，即为实现了铰链10中任意相邻两关节101的相对转动。
在上述实施例的基础上，如图1、图3和图4所示，任意相邻两关节101合拢时，每个关节101的转动轴210的下表面形成一水平贴合面；和/或
至少两个关节101打开时，每个关节101的转动轴210的下表面形成一弧形水平面。
本实施例提供的铰链10，任意相邻两关节101在转动时，关节101的转动轴210的下表面可以连接形成水平表面或者弧形表面作为贴合表面102，通过相邻关节的转动轴210下表面的连接形成的贴合表面102，可以实现由至少两个关节101连接而成的铰链10的拉直与弯曲。
本实施例中，考虑到机械结构的制作误差和转动的不完全贴合性，所形成的水平表面为基本水平而非标准的水平表面，以及，所形成的弧形表面也为基本弯曲而非标准弧形的弧形表面。相邻两关节101在相对转动时，至少两个关节101中的每个关节101可以不位于标准平面上或者标准弧形表面，转动轴210的下表面能够保持在基本水平的水平表面上或者基本弯曲的弧形表面上即可。
具体的，根据每个关节的转动轴的下表面的结构不同，所形成的贴合表面的结构也不相同。
其一，若关节的转动轴的下表面是水平面，则至少两个关节合拢时，至少两个关节的转动轴的下表面连接形成标准的水平面。若至少两个关节打开，则至少两个关节的转动轴的下表面连接形成弧形支撑表面。由于每个关节的转动轴的下表面均为水平面，且相邻关节之间可能存在连接不平整问题，因此，至少两个关节的转动轴的下表面连接形成的弧形支撑表面可能为不标准的弧形面。
其二，若关节的转动轴的下表面是弧面，则至少两个关节合拢时，至少两个关节的转动轴的下表面连接形成的水平支撑表面可能为不标准的水平面。若至少两个关节打开，则至少两个关节的转动轴的下表面可以连接形成标准的弧形支撑表面。当然，关节的转动轴的下表面的弧面的具体弧度和弯曲类型也会影响所形成的弧形支撑表面的弯曲程度，在此不作限定。
本实施例提供的铰链10在使用时，至少两个关节101的转动轴210的下表面连接而成的贴合表面102与所贴合部件贴合，例如与柔性屏贴合。至少两个关节101的支撑部与所述柔性连接件连接形成支撑表面103，所述支撑表面103随着所述贴合表面102伸展，以支撑贴合表面102的开合。转动轴210的下表面与所贴合部件的弯折部贴合，随着所贴合部件弯折部表面的弯曲或者伸展，铰链10通过相邻关节101的打开或者合拢，实现铰链10的贴合表面102随着所贴合部件的弯折部表面的弯曲或者伸展。铰链10的贴合表面102在贴合过程中，总长度保持不变，贴合表面102不易产生折叠或者凹凸，也就不会对所贴合部件的弯折部表面造成挤压损伤。关节101第二端部的柔性连接件400支撑和限制支撑部300的运动，使得铰链10的支撑表面103在一定范围内收缩和拉伸，以支撑所述贴合表面102的收缩和拉伸。
在上述实施例的基础上，如图1至图5所示，所述转动轴210可以为半圆形转动轴210，所述转动轴瓦220的包裹空间与所述转动轴210相匹配。
本实施例提供的铰链10，设置转动轴210为半圆形转动轴210，该半圆形转动轴210包括圆弧形上表面212和水平下表面211，该转动轴轴心213位于转动轴210的水平下表面211上。半圆形转动轴210的圆弧形上表面212与关节基体100围合成该关节101的弧形空隙230，用于容纳相邻关节101的转动轴瓦220。关节101的转动轴瓦220也为近似的半圆形结构，该转动 轴瓦220的瓦合区域与半圆形转动轴210的圆弧形上表面212形状匹配，刚好可以容纳相邻关节101的半圆形转动轴210。该转动轴瓦虚拟轴心221位于其半圆形瓦合区域的下表面上，该半圆形瓦合区域的下表面与所述半圆形转动轴瓦虚拟轴心221所在的下表面重合，也就是说，关节101的转动轴瓦虚拟轴心221位于该关节的转动半轴的下表面所在平面上。这样，任意相邻两关节101在装配时，将第一关节的转动轴瓦220插入到第二关节的弧形空隙230内，以使得该第一关节的转动轴瓦220盖合在第二关节的转动轴210上，以实现第一关节的转动轴瓦220与第二关节的转动轴210之间的相对转动。由于每个关节101的转动轴瓦220的虚拟轴心在其转动轴210的下表面上，因此相邻两关节101相对转动时，相邻关节101的转动轴210的下表面基本位于同一水平面上或者同一弧形表面上，以使得铰链10的贴合表面102可以基本贴合所贴合部件的弯折部表面。
在上述实施例的基础上，如图6和图7所示，至少两个关节101的转动轴210的轴心都在所述铰链10的贴合表面102上，这样，铰链10转动过程中，铰链10的贴合表面102的总长度可以保持不变。
具体的，假设虚拟转动中心的距离为S，该铰链10共有n个关节101。如图6所示，铰链10伸直时，铰链10的贴合表面102的总长度：L＝S*n。
如图7所示，铰链10弯曲时，由于虚拟转动中心的距离S保持不变，而且关节101的总个数不变，则所述铰链10的贴合表面102的总长度：L＝S*n，即铰链10弯曲时贴合表面102的总长度与铰链10伸直时贴合表面102的总长度保持一致。
这样，铰链10的贴合表面102贴合柔性屏等部件时，贴合表面102的总长度保持不变，可以保护所贴合部件不被拉长或者压缩，提升了铰链10的贴合保护效果和支撑作用。
在上述实施例的基础上，如图1至图5所示，所述柔性连接件400的两端分别与所述至少两个关节中位于两端的端关节固定连接，所述至少两个关节中位于两个段关节之间的关节沿所述柔性连接件400的内表面移动。
本实施例提供的铰链10，柔性连接件400配合关节的支撑部300来限制关节的开合，主要是通过柔性连接件400与至少两个关节的两端固定的方案 来实现的。具体的，将柔性连接件400的一端与对应的端关节固定连接，将柔性连接件400的另一端与对应的另一个端关节固定连接。这样，位于至少两个关节的两个端关节之间的中关节106，均位于柔性连接件400内，设置每个中关节106的支撑部300均与柔性连接件400的内表面接触。
这样，至少两个关节的任意两个关节合拢时，两个端关节相靠拢，则柔性连接件400的两端也随之靠拢。任意相邻两关节随着转动结构200的转动而靠拢，则该任意相邻两关节上的支撑部300也随之靠拢，并与柔性连接件400贴合接触。
至少两个关节的任意相邻两关节打开时，两个端关节相背离，柔性连接件400的两端也随之相背离。任意相邻两关节随着转动关节的转动而背离，则该任意相邻两关节沿所述柔性连接件400的内表面移动。
本实施例提供的铰链10，铰链10两端的端关节与柔性连接件400固定，两端之间的关节可以沿着柔性连接件400的内表面移动，有效实现铰链10的至少两个关节及关节所连接的柔性连接件400匹配实现关节的打开与合拢。
在上述实施例的基础上，如图1所示，所述柔性连接件400可以包括至少两个支撑件410以及连接任意相邻两个支撑件410的柔性连接带420，所述支撑部300与支撑件410连接。
本实施例中，铰链10的柔性连接件400包括至少两个支撑件410，任意相邻两个柔性连接件400之间设置通过柔性连接带420连接。柔性连接件400的每个支撑件410对应一个关节的支撑部300，任意相邻两个关节与对应的两个相邻的支撑件410连接，通过该相邻两个支撑件410之间的柔性连接带420，支撑和限制该相邻两关节之间的打开与合拢。
在一种具体实施方式中，如图3和图4所示，所述每个支撑件410设置有与所述支撑部300相匹配的凹槽110，所述支撑部300伸入所述凹槽110内，以实现所述支撑部300与支撑件410的连接。
铰链10的柔性连接件400上设置有至少两个支撑件410，每个支撑件410设置有一个凹槽110，凹槽110与关节的支撑部300相匹配，即每个关节的支撑部300可以伸入到柔性连接件400的一个凹槽110内。铰链10的至少两个关节中的每个关节的支撑部300均伸入到柔性连接件400的一个凹槽110内， 即可实现关节的支撑部300与柔性连接件400的连接。任意相邻两个凹槽110之间设置的柔性连接带420，有效限制对应相邻两关节的支撑部300之间的打开与合拢。
在上述实施例的基础上，如图3和图4所示，任意相邻两关节合拢时，每个关节的支撑部300上套设的关节连接套的外表面形成一水平支撑表面；和/或
至少两个关节打开时，每个关节的支撑部300上连接的关节连接件的外表面形成一弧形支撑表面。
本实施例提供的铰链10，考虑到铰链10在贴合时，每个关节101的转动轴210下表面基本位于同一水平面上或者同一弧形表面上，因此，为保证铰链10贴合的完整性和支撑作用，设置每个关节101的支撑部300与柔性连接件400连接形成的支撑表面103与转动结构200连接形成的贴合表面102保持一致。
即为，任意相邻两关节101合拢时，每个关节101的支撑部300支撑所述柔性连接件400形成一水平支撑面，或者，至少两个关节101打开时，每个关节101的支撑部300支撑所述柔性连接件400形成一弧形支撑面。
在上述实施例的基础上，如图1至图7所示，每个关节101的关节基体100可以包括相背设置的容纳凹槽110和凸块120；
任意相邻两关节101在合拢时，第一关节的凸块120贴合到第二关节的容纳凹槽110内。
本实施例提供的铰链10，为进一步提高相邻两关节101在开合过程中的贴合程度，设置相邻两关节101的关节基体100为相互配合的结构。具体的，关节基体100包括容纳凹槽110和凸块120，容纳凹槽110和凸块120相背设置，且容纳凹槽110的围合空间与凸块120相匹配。任意相邻两关节101在合拢时，第一关节的凸块120可以贴合到第二关节的容纳凹槽110内，使得第一关节与第二关节完整贴合。这样，相邻两关节101在合拢时的贴合程度较高，节省了铰链10合拢后的体积，减小了关节101间的活动缝隙，提高了铰链10合拢的防尘性能、规整性和支撑性能。此外，关节基体100设置相互配合的凸块120和容纳凹槽110，也节省了关节101的制作成本。
在上述实施例的基础上，如图3和图4所示，所述至少两个关节101中，位于两端的首关节104和尾关节105的关节基体100为长条形，所述长条形关节基体100的一端与相邻关节101的转动结构200相套接。
本实施例提供的铰链10，位于两端的关节101定义为端关节，包括首关节104和尾关节105。端关节的关节基体100为长条形，该长条形关节基体100可以包括关节连接端和元件连接端，关节连接端与相邻的中关节106匹配连接，元件连接端与所贴合部件或者所贴合部件的附属元件相连接。
在一种具体实施方式中，关节连接端可以包括转动结构200和支撑部300，用于与相邻中关节106匹配连接。可以仅在该关节连接端连接相邻关节101的转动轴瓦220的位置设置转动轴210与弧形空隙230，以及在该关节连接端连接相邻关节的另一侧位置设置支撑部300。将该端关节连接端相邻的中关节106的转动轴瓦220伸入到该端关节的弧形空隙230内。将该端关节的元件连接端，通过螺钉、胶粘层等连接到所贴合部件或者所贴合元件的附属元件上。这样，该端关节既可以与中关节106匹配连接，又能将该铰链10固定到所贴合部件上。铰链10所包含的关节101的结构基本一致，便于生产加工。
在上述实施例的基础上，如图8和图9所示，任意相邻关节之间还可以设置有限位件500，所述限位件500能够限制该相邻关节之间沿所述转动轴210的轴向相对滑动。
本实施例提供的铰链10，通过相邻关节101在沿转动轴210径向上的相对转动，实现铰链10的伸缩和弯折。此时，铰链10中的至少两个关节101在沿转转动轴210的轴向方向上，维持相对固定状态，以保证相邻关节101之间的稳定连接。为限制关节101在轴向上的相对滑动影响关节101之间的连接稳定性，在相邻关节101之间设置限位件500，以限制该相邻两关节101之间沿所述转动轴210的轴向相对滑动。
在一种具体实施方式中，如图8和图9所示，所述限位件500为销轴，所述相邻关节101中的第一关节上开设有轴孔510，第二关节上对应所述轴孔510的位置开设有轴向限位凹槽520；
所述销轴穿过所述第一关节上的轴孔510伸入到所述第二关节上的轴向 限位凹槽520内，所述轴向限位凹槽520能够限制所述销轴沿所述转动轴210的轴向移动。
确定任意相邻两关节101的重叠区域，在第一关节对应该重叠区域的位置开设轴孔510，并在第二关节对应该重叠区域的位置开设轴向限位凹槽520。第一关节的轴孔510与第二关节的轴向限位凹槽520相通，可以通过第一关节与第二关节的直接接触实现相通，或者通过第一关节与第二关节之间的空隙实现相通。
所述第二关节上设置的轴向限位凹槽520，在转动轴210的轴向方向上的宽度较窄，可以仅等于或者略大于销轴的直径。轴向限位凹槽520沿转动轴210的径向延伸，可以允许销轴在随第一关节与第二关节的开合运动中沿该轴向限位凹槽520运动。
本实施例提供的铰链10，将相邻两关节101装配时，销轴穿过第一关节的轴孔510，并伸入到第二关节的轴向限位凹槽520内。这样，相邻关节101在打开或者合拢时，销轴随着第一关节的转动，在第二关节的轴向限位凹槽520内沿转动轴210的径向滑动，以有效限制相邻关节101之间的轴向滑动，保证了铰链10的连接稳定性。
在上述实施例的基础上，如图8和图9所示，每个关节101内均开设有走线通孔600，任意相邻关节101的走线通孔600相连通。
本实施例提供的铰链10，应用于柔性屏等移动终端时，可能会存在移动终端的绕线外露，影响美观，或者易于铰链10缠绕影响铰链10的正常弯折。因此，可以在关节101内开设走线通孔600，并使得任意相邻关节101的走线通孔600相连通。这样，移动终端的相关走线可以依次穿过铰链10的每个关节101内的走线通孔600后穿出，内部走线避免了外部走线对外在部件和美观造成的影响。
在上述实施例的基础上，每个关节101的第一端部还可以盖合有端盖。
本实施例提供的铰链10，在关节101的第一端部设置端盖，通过端盖盖合在相邻关节101的连接处，既可以避免内部外接外露影响美观，通过端盖盖合可以防水防尘，进一步提高铰链10的封闭性和转动灵敏度。所述端盖可以采用软胶盖等材质，其他能实现遮盖关节101端部的端盖实现方案均可适 用于本实施例，不作限定。
参见图10和图11，本公开的一些实施例还涉及一种移动终端，包括柔性屏20，以及如图1至9中任一项所述的铰链10，所述柔性屏20包括相对设置的显示面202和非显示面203；
所述铰链10的至少两个关节的转动结构连接形成贴合表面102，所述贴合表面102贴合所述柔性屏的弯折部201对应的非显示面203设置；
所述铰链10的至少两个关节的支撑部与柔性连接件连接形成支撑表面103，所述支撑表面103支撑所述柔性屏20的非显示面203。
如图10所示，任意相邻两关节合拢时，每个关节的转动轴的下表面基本位于同一水平面上，形成的贴合表面102为水平面，所述贴合表面102与所述柔性屏20的非显示面203贴合，支撑所述柔性屏20伸展。
如图11所示，至少两个关节打开时，每个关节的转动轴的下表面形成一弧形贴合表面102，关节的支撑部连接关节连接件形成形成一弧形支撑表面103。这样，铰链10的至少两个关节的下表面连接形成弧形的贴合表面102时，柔性屏20随着铰链10打开，能够呈弧形进行平滑的弯折，以使得柔性屏20的外表面也随之形成一个弧形的表面，与弧形贴合表面102贴合。铰链的至少两个关节的下表面连接形成水平的贴合表面102时，柔性屏20随着铰链10合拢，能够呈水平状态伸直，以使得柔性屏20的外表面也随之形成一个水平的表面，与水平贴合表面102贴合。
这样，关节的支撑表面103随着贴合表面102拉伸和弯曲，可以有效支撑贴合表面102与柔性屏20的弯折部201对应的非显示面203的贴合和支撑，不会对弯折部201表面的弯折状态造成限定。
所述移动终端可以包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、以及计步器等任何具有包含支撑可弯折的柔性部件，尤其是贴合柔性屏的铰链的设备，不作限定。
本实施例提供的移动终端，用于贴合柔性屏的铰链包括顺次连接的至少两个相同结构的关节，通过将任意相邻两关节的转动结构相套接，以使得相邻两关节的转动结构相对转动。增设柔性连接件，使得柔性连接件能够随关节之间的开合而开合，且柔性连接件可以限制关节的开合程度。这样，形成 铰链的关节结构相同，便于加工和装配。通过增减关节的数量即可改变铰链的长度，优化了移动终端中的铰链的装配方案。本公开的一些实施例提供的移动终端的具体实施过程，可以参见上述实施例提供的铰链的具体实施过程，在此不再一一赘述。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
