具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
如图1-图9所示，本申请实施例公开一种铰链机构，该铰链机构可以与柔性屏配合，形成折叠式电子设备，这种电子设备具备折叠状态和展开状态，且在电子设备处于折叠状态的情况下，使得电子设备在各方向上的整体尺寸均相对较小，进而使电子设备具有较强的便携能力；在电子设备处于展开状态的情况下，电子设备的显示屏具有较大的显示面积，可以为用户提供较好的观感。
当然，为了保证柔性屏可以与铰链机构形成稳定的装配关系，上述铰链机构通常还配设有机壳。具体来说，铰链机构的相背两侧均可以设置有机壳(图中未示出)，显示屏可以固定在机壳上，以使机壳能够为显示屏提供支撑作用，且在相邻的两个机壳相对转动的过程中，可以带动显示屏产生相应的折叠或展开动作。
铰链机构包括安装组件、第一转动件210和第二转动件220，其中，第 一转动件210和第二转动件220的结构可以不同，在本申请的另一实施例中，第一转动件210和第二转动件220的结构对称设置，以提升铰链机构与其相背两侧的机壳之间连接效果，从而使两个机壳各自与铰链机构之间的转动动作相互对应，提升电子设备的精度。
相应地，为了保证铰链机构能够与设置于其相背两侧的机壳形成装配关系，铰链机构中的第一转动件210和第二转动件220分别设置于安装组件的相背两侧，从而使得安装组件可以分别利用第一转动件210和第二转动件220与前述两个机壳相互连接。具体地，第一转动件210和机壳之间，以及第二转动件220和机壳之间均可以通过焊接等方式形成固定连接关系；在本申请的另一实施例中，第一转动件210和第二转动件220各自与机壳之间均可以通过螺纹连接件形成可拆卸地固定连接关系，以便于后期维护和保养。
安装组件包括安装座110和同步件120，如上所述，第一转动件210和第二转动件220分别设置于安装组件的相背两侧，在安装组件包括安装座110的情况下，可以使第一转动件210和第二转动件220分别设置于安装座110的相背两侧；同时，同步件120位于安装座110的一面。详细地说，安装座110具有相背的第一侧和第二侧，且安装座110还具有相背的第一面和第二面，且第一面、第一侧、第二面和第二侧四个空间沿围绕铰链机构的转动轴向的方向依次分布，也即，第一侧位于第一面和第二面的一侧，第二面位于第一面和第二面的另一侧，其中，第一转动件210位于安装座110的第一侧，第二转动件220位于安装座110的第二侧，同步件120位于安装座110的第一面。
另外，需要说明的是，上述对于第一转动件210和第二转动件220二者与安装座110之间的位置关系，是以铰链机构处于展开状态为例进行描述地，而如果以铰链机构处于折叠状态来说，则第一转动件210和第二转动件220均可以相对安装座110转动至安装座110的第二面，也即，在折叠状态下，第一转动件210和第二转动件220均位于安装座110中背离同步件120的另 一面。
并且，为了保证同步件120可以提供同步作用，同步件120与安装座110在安装座110的长度方向上活动配合，以利用同步件120使第一转动件210和第二转动件220能够同步地相对安装座110转动。需要说明的是，安装座110的长度方向即为铰链机构的转动轴向。如上所述，同步件120设置于安装座110的一面，且由于安装座110与同步件120在安装座110的长度方向上活动配合，为了保证同步件120能够与安装座110形成可靠的配合关系，可以在二者之间设置滑动连接件，且通过使同步件120和安装座110均与滑动连接件在垂直于安装座110的方向上相互限位。其中，垂直于安装座110的方向具体可以为安装座110的厚度方向，或者说，可以为安装座110和同步件120之间的分布方向。
如图2所示，同步件120设有第一限位槽121a和第二限位槽122a，第一转动部包括第一连接部211、第一转动臂212和第一驱动臂213，第二转动部包括第二连接部221、第二转动臂222和第二驱动臂223。其中，第一转动臂212和第一驱动臂213均与第一连接部211连接，且第一转动臂212和第一驱动臂213均位于第一连接部211的同一侧。更具体地说，第一转动臂212和第一驱动臂213均用以与安装座110配合，第一连接部211用以与上述机壳固定连接，从而使第一转动部能够与安装座110形成转动连接关系。相似地，第二转动臂222和第二驱动臂223均与第二连接部221连接，且第二转动臂222和第二驱动臂223均位于第二连接部221的同一侧。更具体地说，第二转动臂222和第二驱动臂223均用以与安装座110配合，第二连接部221用以与另一机壳固定连接，从而使第二转动部能够与安装座110形成转动连接关系。
在组装铰链机构的过程中，第一转动件210通过其第一转动臂212与安装座110转动配合，第二转动件220通过其第二转动臂222与安装座110转动配合，以使第一转动件210和第二转动件220均可以沿围绕安装座110的 长度方向的方向(即围绕铰链机构的转动轴向的方向)与安装座110转动配合。具体地，以第一转动臂212为例，可以在安装座110上设置弧形凹槽，且使第一转动臂212安装在前述弧形凹槽内，从而使第一转动臂212能够在弧形凹槽内运动，以使第一转动臂212和安装座110能够形成转动配合关系；反之，通过在安装座110上设置弧形凸块，且在第一转动臂212上设置弧形凹槽，亦可以使第一转动臂212和安装座110能够形成转动配合关系。当然，第一转动臂212和安装座110还可以采用其他形式的结构相互连接，且形成转动配合关系，考虑文本简洁，此处不再一一介绍；另外，第二转动臂222和安装座110之间亦可以参照上述第一转动臂212的结构形式，使第二转动臂222能够与安装座110形成转动配合关系。
如上所述，第一驱动臂213为第一转动件210中的部件，第二驱动臂223为第二转动件220中的部件，第一转动件210和第二转动件220分别连接于安装座110，且第一转动件210和第二转动件220分别与铰链机构相背两侧的机壳连接，在这种电子设备的折叠和展开过程中，以安装座110为参考系，铰链机构相背两侧的机壳的转动方向相反，相应地，与两个机壳分别固定连接的第一转动件210和第二转动件220的转动方向亦相反。
基于上述内容，在本申请实施例公开的铰链机构中，为了保证第一转动件210和第二转动件220能够具备同步转动的功能，如图4所示，第一驱动臂213和第二驱动臂223均围绕安装座110的长度方向螺旋延伸，且二者的旋向相反，同时，第一驱动臂213与同步件120的第一限位槽121a滑动配合，第二驱动臂223与同步件120的第二限位槽122a滑动配合，进而，在第一转动件210相对安装座110沿第一旋向转动的情况下，使得与第一限位槽121a螺旋配合的第一驱动臂213能够驱动同步件120相对安装座110沿安装座110的长度方向运动，也即，利用螺旋延伸的第一驱动臂213，可以将第一转动件210的旋转驱动力转化为直线驱动力，在直线驱动力的作用下，可以驱动同步件120相对安装座110沿螺旋的轴向，也即安装座110的长度方向运动。
继而，由于同步件120还通过其第二限位槽122a与第二驱动臂223配合，从而在同步件120相对安装座110作直线运动的过程中，会向第二驱动臂223施加直线作用力，由于第二驱动臂223为螺旋结构，从而使得同步件120可以驱动第二驱动臂223相对安装座110转动，进而带动整个第二转动件220相对安装座110转动；同时，由于第二驱动臂223的螺旋方向与第一驱动臂213的螺旋方向相反，从而使得同步件120能够驱动第二驱动臂223相对安装座110沿相反于第一旋向的第二旋向转动，保证第一转动件210和第二转动件220能够同步转动，且使二者的转动方向相反。
具体地，螺旋结构的第一驱动臂213和第二驱动臂223各自的具体参数均可以根据实际情况确定，此处不作限定。另外，第一连接部211、第一转动臂212和第一驱动臂213三者可以采用金属等硬质材料分体成型，且通过焊接或热熔结等方式连为一体；或者，还可以采用一体成型的方式，一并形成包括第一连接部211、第一转动臂212和第一驱动臂213的第一转动件210。相似地，第二转动件220的形成方式可以参照第一转动件210，此处不再重复说明。另外，可以通过刻蚀等方式在同步件120的一侧表面形成第一限位槽121a和第二限位槽122a，当然，亦可以采用一体成型的方式直接形成具有第一限位槽121a和第二限位槽122a的同步件120，第一限位槽121a和第二限位槽122a均可以为直线槽，二者的宽度和长度等尺寸可以分别根据第一驱动臂213和第二驱动臂223的具体尺寸确定，此处不作限定。
本申请实施例公开一种铰链机构，该铰链机构包括安装组件，以及连接于安装组件相背两侧的第一转动件210和第二转动件220。第一转动件210中的第一转动臂212转动连接于安装座110的一侧，第二转动件220中的第二转动臂222转动连接于安装座110的另一侧，从而使得第一转动件210和第二转动件220均能够与安装座110形成转动配合关系。
同时，安装组件中的安装座110的一面设置有同步件120，同步件120与安装座110在安装座110的长度方向上活动配合，且同步件120设有第一 限位槽121a和第二限位槽122a，第一转动件210中的第一驱动臂213与第一限位槽121a滑动配合，第二转动件220中的第二驱动臂223与第二限位槽122a滑动配合，第一驱动臂213和第二驱动臂223均为围绕安装座110的长度方向螺旋延伸的螺旋结构，且第一驱动臂213和第二驱动臂223的旋向相反，从而在第一转动件210相对安装座110沿第一旋向转动的情况下，使得第一转动件210可以通过其第一驱动臂213驱动同步件120相对安装座110沿安装座110的长度方向运动，利用同步件120驱动第二驱动臂223转动，使第二转动件220沿相反于第一转动件210的方向相对安装座110转动，实现第一转动件210和第二转动件220能够相对安装座110同步转动的目的。
并且，上述结构在铰链机构中所占的空间相对较小，且部件间相互配合可以进一步减小整个铰链机构的整体尺寸，从而可以降低铰链机构在电子设备中所占的空间，有利于电子设备中其他部件的布局工作的进行。
如上所述，安装座110上可以设有弧形凹槽，且使第一转动臂212伸入弧形凹槽内，使第一转动臂212和安装座110形成转动配合关系。在本申请的另一实施例中，如图2所示，安装座110设有第一容纳槽111，且第一容纳槽111沿安装座110的长度方向相对的两个侧壁中的一者设有第一弧形配合部140，第一转动臂212的一侧设有第二弧形配合部201，第二弧形配合部201与第一容纳槽111的第一弧形配合部140转动配合，且第一弧形配合部140和第二弧形配合部201中的一者为弧形沉槽，另一者为弧形凸起，进而使第一转动臂212能够与安装座110形成转动配合关系。
在采用上述技术方案的情况下，受安装座110上的第一容纳槽111的限制，使得第一转动臂212和安装座110可以在安装座110的长度方向上相互限位，受第一弧形配合部140和第二弧形配合部201的相互作用，使得第一转动臂212和第二转动臂222可以在垂直于安装座110的长度方向的方向上相互限位；并且，互相配合的第一转动臂212和第一容纳槽111，以及互相配合的第一弧形配合部140和第二弧形配合部201均可以为第一转动臂212 与安装座110之间的转动配合关系提供保障作用，从而使第一转动臂212和安装座110之间的转动配合关系更为稳定和可靠。
为了提升安装座110的整体结构强度，可以使设置在第一容纳槽111的侧壁上的第一弧形配合部140为弧形凸起，且使设置在第一转动臂212的侧面上的第二弧形配合部201为弧形沉槽，弧形凸起和弧形沉槽的结构和尺寸相互对应，以保证二者能够想成转动配合关系。
相似地，安装座110中与第二转动臂222对应的位置处亦可以设置第一容纳槽111，且在第一容纳槽111的侧壁上设置第一弧形配合部140，相应地，通过在第二转动臂222上设置第二弧形配合部201，使得第二转动臂222亦能够与安装座110形成稳定、可靠的转动配合关系。
当然，亦可以在第一容纳槽111中相对的两个侧壁上均设置第一弧形配合部140，以进一步提升第一转动臂212(和第二转动臂222)和安装座110之间转动配合关系的稳定性。综合加工成本、加工难度和稳定性等多方面因素考虑，如图2所示，可以仅在第一容纳槽111的一个侧壁上形成第一弧形配合部140，且可以使第一转动臂212上的第二弧形配合部201与第二转动臂222上的第二弧形配合部201沿安装座110的长度方向相背设置，这也可以使第一转动臂212(和第二转动臂222)均能够与安装座110形成较为稳定的转动配合关系。
如上所述，第一转动件210中的第一驱动臂213还与位于安装座110一面的同步件120配合，为此，在第一转动件210中的第一转动臂212安装于安装座110的第一容纳槽111内的情况下，还可以通过缩小安装座110的长度，使第一驱动臂213能够位于安装座110之外，从而防止安装座110妨碍第一驱动臂213与位于安装座110另一面的同步件120配合。或者，在安装座110的长度相对较长的情况下，还可以通过在安装座110上设置另外的槽状结构，且使该槽状结构贯穿安装座110，从而使第一驱动臂213能够穿过前述槽状结构与安装座110另一面的同步件120配合。
为了尽量降低安装座110的加工难度，可以使第一容纳槽111贯穿安装座110设置，这使得第一驱动臂213的一部分能够穿过第一容纳槽111，且伸入同步件120的第一限位槽121a内，使第一驱动臂213能够与同步件120形成可靠的配合关系。在采用上述技术方案的情况下，安装座110上的同一槽结构(即第一容纳槽111)可以同时与第一驱动臂213和第一转动臂212配合，在保证安装座110具有相对较长的尺寸，以具有更宽泛的安装能力的同时，还可以使安装座110轻量化，提升安装座110的整体性能。
相应地，安装座110中用于与第二转动件220配合的另一第一容纳槽111亦可以为贯穿式结构，使第二转动件220的第二转动臂222和第二驱动臂223可以一并被安装在安装座110的另一第一容纳槽111内，且使第二驱动臂223的一部分亦可以穿过该第一容纳槽111，且与同步件120的第二限位槽122a配合，使第二转动件220与同步件120形成可靠的配合关系。
如上所述，第一转动件210包括第一转动臂212和第一驱动臂213，进一步地，第一转动件210还包括第一悬停臂214，第一悬停臂214固定在第一连接部211上，且第一悬停臂214位于第一连接部211中第一转动臂212所在的一侧，也即，第一转动臂212、第一驱动臂213和第一悬停臂214均位于第一连接部211的同一侧。具体地，第一悬停臂214可以通过粘接等方式固定在第一连接部211上，在本申请的另一实施例中，第一悬停臂214可以通过一体成型的方式随第一连接部211一并形成，以提升二者之间的连接可靠性。
安装座110上设有第二容纳槽112，且第二容纳槽112沿长度方向相对的两个侧壁中的一者设有第一弧形配合部140，第一悬停臂214的一侧设有第二弧形配合部201，且第一悬停臂214上的第二弧形配合部201用以与第二容纳槽112上的第一弧形配合部140转动配合，这使得第一悬停臂214亦能够与安装座110形成转动配合关系，以进一步提升第一转动件210与安装座110之间转动配合关系的可靠性和稳定性。
相似地，设置于第二容纳槽112内的第一弧形配合部140和设置于第一悬停臂214上的第二弧形配合部201中的一者可以为弧形凸起，另一者可以为弧形沉槽。考虑到上文已经对第一弧形配合部140和第二弧形配合部201的具体结构进行了详细说明，此处不再重复。更具体地，设置于第二容纳槽112内的第一弧形配合部140可以为弧形凸起，从而提升安装座110的整体结构稳定性，设置于第一悬停臂214上的第二弧形配合部201可以为弧形沉槽，以降低加工难度。
并且，可以仅在第一容纳槽111上沿长度方向相对的两个侧壁中的一者上设置第一弧形配合部140，为此，可以使设置在第一容纳槽111的第一弧形配合部140和设置于第二容纳槽112内的第一弧形配合部140相背设置。也即，两个第一弧形配合部140可以设置在第一容纳槽111和第二容纳槽112相互临近的侧壁上，亦可以设置在第一容纳槽111和第二容纳槽112相互背离的侧壁上，从而使两组相互配合的第一弧形配合部140和第二弧形配合部201，能够为第一连接件和安装座110提供沿长度方向的限位作用，防止第一连接件与安装座110在长度方向上存在晃动的情况。
更具体地，如图2所示，可以使设置于第一转动臂212的弧形沉槽的开口与设置于第一悬停臂214的弧形沉槽的开口相背。在这种情况下，两个第一弧形配合部140分别设置在第一容纳槽111和第二容纳槽112相互临近的侧壁上。在采用上述技术方案的情况下，使得设置于第一容纳槽111内的第一弧形配合部140与设置于第二容纳槽112内的第二弧形配合部201在长度方向上的间距最大，从而在利用两个第一弧形配合部140为第一连接件提供转动作用时，使第一连接件与安装座110之间的转动间距相对较大，这可以提升第一连接件与安装座110之间的转动稳定性。
考虑到第一转动件210和第二转动件220整体上呈对称设置，为此，上述实施例中所涉及的第一转动件210的结构特征，亦可以对应地应用至第二转动件220中，以提升第二转动件220与安装座110之间转动配合关系的稳 定性。
如上所述，第一转动件210包括第一悬停臂214，第一悬停臂214固定于第一连接部211中第一转动臂212所在的一侧，且第二转动件220可以包括第二悬停臂224，第二悬停臂224固定于第二转动部中第二转动臂222所在的一侧，为了使第一悬停臂214和第二悬停臂224能够分别使第一转动件210和第二转动件220具备相对安装座110悬停的能力，第一悬停臂214和第二悬停臂224均配设有阻尼组件300。
详细地说，阻尼组件300包括弹性件310，且弹性件310的弹性方向包括沿安装座110的长度方向的分量，也即，弹性件310能够提供沿安装座110的长度方向的弹性作用力，以利用弹性件310提供的弹性作用力是第一悬停臂214和第二悬停臂224具备悬停能力。
更具体地说，第一悬停臂214设有第一抵接面，第二悬停臂224设有第二抵接面224a，各弹性件310的第一端均抵接于安装座110，且多个弹性件310中，至少一者的第二端挤压于第一抵接面，且该弹性件310的第二端沿第一抵接面移动，至少其他一者的第二端挤压于第二抵接面224a，且该弹性件310的第二端沿第二抵接面224a移动。
也即，在本申请实施例中，通过使抵接于安装座110和第一悬停臂214之间的弹性件310处于被压缩状态的方式，使得弹性件310可以向第一悬停臂214施加垂直于安装座110的长度方向的摩擦力，进而限制第一悬停臂214与安装座110之间产生相对转动，使第一悬停臂214产生阻尼效果，从而使第一悬停臂214具备相对安装座110悬停的能力，且使与第一悬停臂214连接的屏幕支撑部能够在其转动范围内的任意角度悬停。相似地，与第二悬停臂224连接的屏幕支撑部亦能够在其转动方位内的任意角度悬停。
具体地，安装座110、第一悬停臂214和第二悬停臂224上均可以设有限位柱，且通过使弹性件310的相背两端分别套设于限位柱之外的方式，保证弹性件310与安装座110之间的组装关系较为稳定。如上所述，安装座110 的第二容纳槽112中沿长度方向相对的两个侧壁中的一者上可以设置有第一弧形配合部140，为此，可以使弹性件310的第一端抵接于前述两个侧壁的另一者上，且使弹性件310的第二端能够抵接于安装于第二容纳槽112内的第一悬停臂214(或第二悬停臂224)的表面。
当然，还可以使弹性件310的第一端抵接于安装座110上的其他位置处，例如，可以在安装座110上背离第一悬停臂214中第二弧形配合部201的一侧为弹性件310设置避让区，从而增大弹性件310在长度方向上的安装空间，一方面可以提升弹性件310的伸缩稳定性，另一方面，还可以减小第一悬停臂214(即第一转动件210)与安装座110在长度方向上的活动范围，提升第一转动件210与安装座110之间的连接可靠性。相似地，对于与安装座110另一侧的第二容纳槽112配合的第二悬停臂224而言，亦可以为与第二悬停臂224配合的弹性件310在第一安装座110背离第二悬停臂224中第二弧形配合部201的一侧设置避让区，且使对应的弹性件310安装于前述避让区内，提升该弹性件310的伸缩稳定性以及第二连接件与安装座110之间的配合稳定性。
更进一步地，第一抵接面包括第一平面214a、第二平面214b和第三平面214c，且三者依次连接；也即，沿第一悬停臂214的延伸方向，第一平面214a、第二平面214b和第三平面214c依次分布。更具体地说，第一平面214a位于第一悬停臂214相对于第一连接部211的近端，第三平面214c位于第一悬停臂214相对于第一连接部211的远端。
并且，沿长度方向，第一平面214a和第三平面214c各自与弹性件310的第一端之间的间距均大于第二平面214b与弹性件310的第一端之间的间距，也就是说，相较于弹性件310的第二端与第二平面214b配合的状态，在弹性件310的第二端与第一平面214a(或第三平面214c)配合时，弹性件310的被压缩程度相对更小，也即，在弹性件310与第二平面214b配合使，弹性件310的压缩势能最大。当然，第一平面214a与弹性件310的第一端的间距与 第二平面214b与弹性件310的第一端端的间距之间的差值可以根据实际情况选定，且可以使第一平面214a与弹性件310的第一端之间的间距等于或大于弹性件310处于自然状态时在长度方向上的尺寸，进而使得弹性件310能够抵接于第一平面214a和安装座110之间。并且，可以使第三平面214c与第一平面214a在长度方向上平齐，以降低第一抵接面的加工难度。
另外，第一平面214a和第三平面214c各自与第二平面214b之间均平滑过渡，从而保证弹性件310在与第一抵接面配合时，能够顺畅地在第一平面214a、第二平面214b和第三平面214c中任意相邻的两者之间切换。具体来说，可以在第一平面214a和第二平面214b之间设置弧形过渡面，且在第二平面214b和第三平面214c之间设置弧形过渡面，这可以保证弹性件310能够顺畅地相对第一抵接面运动。
并且，在铰链机构处于展开状态的情况下，弹性件310的第二端挤压于第一平面214a，在铰链机构处于折叠状态的情况下，弹性件310的第二端挤压于第三平面214c。也即，在铰链机构自展开状态切换至折叠状态的过程中，弹性件310的第二端先后分别与第一平面214a、第二平面214b和第三平面214c相抵接，反之，在铰链机构自折叠状态切换至展开状态的过程中，弹性件310的第二端先后分别与第三平面214c、第二平面214b和第一平面214a相抵接。
在采用上述技术方案的情况下，由于弹性件310与第二平面214b抵接时，弹性件310的被压缩程度最大，为此，利用第一平面214a和第二平面214b之间的平滑过渡面，当铰链机构自折叠状态逐渐展开时，使得弹性件310在与第二平面214b抵接的状态切换至与第一平面214a抵接的状态的过程中，能够使弹性件310释放一定的弹性作用力，从而使弹性件310自动自第二平面214b切换至第一平面214a，从而使铰链机构较容易展开到位，提升用户体验。相似地，利用第二平面214b和第三平面214c之间的平滑过渡面，当铰链机构自展开状态逐渐折叠时，使得弹性件310在与第二平面214b抵接的 状态切换至与第三平面214c抵接的状态的过程中，能够使弹性件310释放一定的弹性作用力，从而使弹性件310自动自第二平面214b切换至第三平面214c，从而使铰链机构较容易折叠到位。
另外，在采用上述技术方案的情况下，当铰链机构处于悬停状态时，弹性件310的第二端基本均与第二平面214b抵接，且第二平面214b与弹性件310的第一端之间的间距相对较小，从而还可以提升铰链机构提供悬停作用时的稳定性和可靠性，且可以提升阻尼感，进而提升用户体验。
当然，为了提升第一悬停臂214与对应的弹性件310相对运动时的顺畅性，可选地，本申请实施例公开的铰链机构中，阻尼组件300还可以包括凸轮320，且凸轮320设置在弹性件310的第二端，凸轮320与第一抵接面点接触或线接触。也即，在本申请实施例中，与第一悬停臂214对应的弹性件310通过凸轮320与第一悬停臂214活动连接，且通过使凸轮320与第一悬停臂214之间点接触或线接触的方式，减小凸轮320与第一悬停臂214之间的接触面积，降低凸轮320与第一悬停臂214之间的接触面积，提升二者之间的动作顺畅性。
具体地，凸轮320与弹性件310之间可以通过嵌套的方式相互连接，或者，还可以利用粘接等方式，将弹性件310的第二端固定在凸轮320背离第一悬停臂214的一端端面。凸轮320朝向第一悬停臂214的一端设有球形面，以与第一悬停臂214形成点接触配合状态，或者，凸轮320朝向第一悬停臂214的一端设有圆柱侧面状结构，以使凸轮320与第一悬停臂214形成线接触配合关系。
如上所述，弹性件310的弹性方向具有沿安装座110的长度方向的分量，可选地，弹性件310的弹性方向平行于安装座110的长度方向，一方面便于弹性件310的安装，另一方面，还可以使弹性件310的弹性力的有效性最大化。
基于上述实施例，可以使凸轮320设有导向柱330，且使安装组件设有 导向槽，导向槽沿安装座110的长度方向延伸，从而使导向柱330与导向槽能够在安装座110的长度方向上滑动配合，利用导向柱330为凸轮320随弹性件310的伸缩相对安装座110运动提供导向和限位作用，提升凸轮320与安装座110之间相对运动过程的稳定性。
具体地，凸轮320和导向柱330可以通过一体成型的方式形成，以提升二者之间的连接可靠性，导向柱330具体可以为圆柱状结构件，以提升其与导向槽的配合顺畅性，防止二者之间出现卡滞的情况。
如上所述，安装组件包括安装座110和同步件120，且同步件120可以通过滑动连接件等结构与安装座110在垂直于安装座110的方向形成稳定的配合关系。在本申请的另一实施例中，安装组件还可以包括基座130，基座130设置于安装座110朝向同步件120的一侧，也即，同步件120可以被夹设在安装座110和基座130之间；并且，利用螺钉等连接件，可以使基座130与安装座110形成可拆卸地固定连接关系，从而利用基座130和安装座110能够为同步件120提供沿垂直于安装座110的方向的限位作用，保证同步件120与安装座110形成稳定的装配关系。上述垂直于安装座110的方向亦可以被认为是安装座110的厚度方向。
另外，在上述实施例中，可以使弹性件310的弹性方向平行于安装座110的长度方向，基于此，沿垂直于安装座110的长度方向和厚度方向的方向上，可以使与第一悬停臂214配合的弹性件310和与第二悬停臂224配合的弹性件310间隔设置，在这种情况下，使得与两个弹性件310分别配合的第一悬停臂214和第二悬停臂224在垂直于安装座110的长度方向和厚度方向的方向上的活动范围亦相对较大，从而防止第一悬停臂214与第二转动部之间，以及第二悬停臂224与第一转动部之间存在相互妨碍的情况，且可以使第一悬停臂214和第二悬停臂224的尺寸具有冗余，提升第一悬停臂214和第二悬停臂224与凸轮320配合时的可靠性。
如上所述，显示屏可以支撑在屏幕支撑部和铰链机构上，利用安装座110 可以为显示屏提供一定的支撑作用，为了使显示屏的被支撑效果相对更好，可选地，本申请实施例公开的铰链机构还可以包括第一支撑部410和第二支撑部420，第一支撑部410和第二支撑部420均用于支撑电子设备的显示屏。具体地，第一支撑部410和第二支撑部420均可以为板状结构，或者，二者均包括板状结构的支撑件，以利用板状结构的支撑件为显示屏提供较为稳定和均匀的支撑作用，保证显示屏的显示效果相对较好，且使显示屏的使用寿命相对较长。
同时，第一支撑部410固定于第一转动件210，第二支撑部420固定于第二转动件220，进而随第一转动件210和第二转动件220的相对转动，使第一支撑部410和第二支撑部420亦能够相对转动，从而在显示屏被折叠的过程中，保证第一支撑部410和第二支撑部420通过相对转动的方式为显示屏提供避让空间，保证显示屏不会因折叠而被挤压。另外，为了提升第一支撑部410和第二支撑部420的动作稳定性，还可以使第一支撑部410和第二支撑部420均与安装座110形成转动配合关系。
如上所述，可以通过在铰链机构中设置第一支撑部410和第二支撑部420为显示屏提供支撑作用，且在上述实施例中，可以使第一支撑部410与第一转动件210相互固定，且使第二支撑部420与第二转动件220相互固定。
在本申请的另一实施例中，可以使安装座110和第一转动件210均与第一支撑部410转动连接，且使安装座110和第二转动件220均与第二支撑部420转动连接，进而使第一支撑部410具备相对第一转动件210转动的能力，且使第二支撑部420具备相对第二转动部转动的能力。基于此，在铰链机构处于折叠状态的情况下，可以使第一支撑部410和第二支撑部420呈扩口状结构，且使二者形成的扩口朝向安装座110所在的方向。
具体地，可以通过在第一支撑部410和第二支撑部420上设置对应的转动结构，且使转动结构具有预设的转动轨迹，以在第一支撑部410被安装至安装座110和第一转动件210上，且在第二支撑部420被安装至安装座110 和第二转动件220上的情况下，当第一转动件210和第二转动件220均相对安装座110转动时，使得第一支撑部410和第二支撑部420能够随之转动，且最终转动至呈扩口状态。在采用上述技术方案的情况下，使得第一支撑部410和第二支撑部420可以为显示屏提供更大的避让空间，且适应于显示屏中被弯折的部分的形状，进一步防止显示屏在折叠过程中出现被挤压的情况。
如上所述，同步件120设有第一限位槽121a和第二限位槽122a，以分别为第一驱动臂213和第二驱动臂223提供驱动作用，从而使第一转动件210和第二转动件220形成同步动作关系。具体地，同步件120包括第一限位部121和第二限位部122，第一限位部121和第二限位部122固定连接，第一限位槽121a可以设置于第一限位部121上，第二限位槽122a可以设置于第二限位部122上。更具体地，第一限位部121和第二限位部122可以采用一体成型的方式形成，以提升同步件120的整体结构稳定性，进而为第一转动件210和第二转动件220提供可靠的同步作用效果。
其中，在形成第一限位槽121a和第二限位槽122a的过程中，沿安装座110的长度方向，可以使第一限位槽121a和第二限位槽122a间隔设置，保证第一驱动臂213和第二驱动臂223在相对运动的过程中不会相互妨碍。并且，使第一限位部121和第二限位部122的至少一部分层叠设置，也即，第一限位部121和第二限位部122在长度方向上的投影部分重叠，从而使第一限位部121和第二限位部122在安装座110的长度方向上所占用的空间可以相对较小，减小同步件120在长度方向上的尺寸，进而使整个铰链机构的尺寸相对较小。
基于上述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，其包括显示屏和多个屏幕支撑部，以及上述任一实施例公开的铰链机构。可选地，屏幕支撑部的数量可以为两个，两个屏幕支撑部可以分别为第一屏幕支撑部和第二屏幕支撑部。在组装电子设备的过程中，利用粘接或螺钉等连接件，可以使第一屏幕支撑部与第一连接部211固定连接，且使第二屏幕支 撑部与第二连接部221固定连接，以使第一屏幕支撑部和第二屏幕支撑部可以通过铰链机构形成转动配合关系；同时，显示屏支撑于第一屏幕支撑部和第二屏幕支撑部上，从而在铰链机构的作用下，使第一屏幕支撑部和第二屏幕支撑部可以带动显示屏在折叠状态和展开状态之间相互切换。
