下面结合图1至图15描述根据本发明实施例的电子设备的铰链组件100。
根据本发明实施例的电子设备的铰链组件100，用于电子设备，电子设备包括第一部分和第二部分，铰链组件100包括：支撑座10、第一活动件20、第二活动件30和阻尼组件40，电子设备包括第一部分和第二部分。
具体而言，第一活动件20可活动地与支撑座10连接，第一活动件20上设有适于与第一部分连接的第一安装部21，第二活动件30可活动地与 支撑座10连接，第二活动件30与第一活动件20相对设置，第二活动件30上设有适于与第二部分连接的第二安装部31，阻尼组件40设有第一配合部41和第二配合部42，第一活动件20和第一配合部41中的一个上设有第一通道43，第一活动件20和第一配合部41中的另一个可活动地配合在第一通道43内，且与第一通道43的内壁面相抵，第二活动件30和第二配合部42中的一个上设有第二通道44，第二活动件30和第二配合部42中的另一个可活动地配合在第二通道44内，且与第二通道44的内壁面相抵，第一活动件20绕自身的轴线可转动，以使阻尼组件40和第一活动件20之间产生阻尼，第二活动件30绕自身的轴线可转动，以使阻尼组件40和第二活动件30之间产生阻尼。
换言之，如图1和图7所示，根据本发明实施例的电子设备的铰链组件100主要由能够起到支撑作用的支撑座10、与支撑座10活动连接的第一活动件20、与支撑座10活动连接的第二活动件30、分别与第一活动件20和第二活动件30连接的阻尼组件40组成。其中，如图16和图18所示，电子设备包括第一部分和第二部分，例如，可折叠的柔性终端设备在折叠过程中可以形成第一部分和第二部分，在铰链组件100处于平整状态的条件下，此时已搭载在铰链组件100上的柔性屏可以展平用来读写。在铰链组件100处于弯折状态的条件下，此时已搭载在铰链组件100上的柔性终端设备可以折叠，以缩小柔性终端设备的体积。本申请的铰链组件100能够带动柔性屏折叠弯曲。需要说明的是，本申请的铰链组件100不仅可以适用于柔性屏等柔性终端设备，也可以用于电子设备中其他需要折叠、展开操作的结构。
此外，如图2所示，在第一活动件20上设有第一安装部21，通过第一安装部21能够实现第一活动件20与第一部分之间的连接。在第二活动件30上设有第二安装部31，通过第二安装部31能够实现第二活动件30与第二部分之间的连接。由于第一活动件20和第二活动件30分别能够绕自身的轴线可旋转，因此，在第一活动件20转动的过程中，第一安装部21也能够转动，从而带动第一部分转动，或者在第一部分转动时，第一安装部21也能够转动，从而带动第一活动件20转动。第二活动件30的转动过程与第一活动件20的转动过程相同，在此不作赘述。
可选地，如图16至图18所示，第一部分包括第一壳体201，第一安装部21与第一壳体201连接，以带动第一壳体201活动。第二部分包括第二壳体202，第二安装部31与第二壳体202连接，以带动第二壳体202活动。在安装时，铰链组件100可以通过螺丝、铆接、焊接或其他方式与第一壳体201或第二壳体202连接。通过铰链组件100能够使第一壳体201和第二壳体202以多个角度的折叠方式合在一起，也可以展平成终端平面设备，比如搭载柔性屏幕，形成折叠柔性终端。
如图1至图18所示，在支撑座10的一侧还设置有阻尼组件40，如图15所示，在阻尼组件40上设有第一配合部41和第二配合部42。第一配合部41与第一活动件20相对应，在第一配合部41和第一活动件20中的一个上设有第一通道43。例如，如图13所示，在第一配合部41上设有第一通道43，此时第一活动件20的一部分能够插接在第一通道43内。或者，在第一活动件20上设有第一通道43，此时第一配合部41的一部分能够插接在第一通道43内。同样的，第二配合部42与第二活动件30相对应，在第二配合部42和第二活动件30中的一个上设有第二通道44。例如，如图13所述，在第二配合部42上设有第二通道44，此时第二活动件30的一部分能够插接在第二通道44内。或者，在第二活动件30上设有第二通道44，此时第二配合部42的一部分能够插接在第二通道44内。
需要说明的是，插接在第一通道43的第一活动件20的至少一部分能够与第一通道43的内壁面相抵，以使第一活动件20与第一通道43的内壁面之间形成滑动摩擦，其中，第一活动件20与第一通道43的内壁面之间相抵可以是一部分相抵，也可以是两者之间过盈配合。在第一活动件20转动时，第一通道43的内壁面和插接部分的外壁面之间会产生摩擦力形成扭矩。同样的，第二通道44的内壁面和对应的插接部分的外壁面之间会产生摩擦力形成扭矩。可选地，如图8所示，可以通过卡簧限定第一活动件20和第一配合部41之间的相对位置关系，具体地，可以将穿出第一通道43的插接部分与卡簧连接，避免插接部分从第一通道43脱落。
下面以第一配合部41上设有第一通道43和第二配合部42上设有第二通道44为例详细说明。
如图1至图6所示，在支撑座10的一侧还设置有阻尼组件40，在阻 尼组件40上分别设有第一通道43和第二通道44。第一通道43与第一活动件20相对应，第二通道44与第二活动件30相对应。具体地，第一活动件20的一部分插接在第一通道43内，第一活动件20与第一通道43呈轴孔配合。由于第一活动件20的一部分与第一通道43的内壁面相抵，因此，在第一活动件20绕自身轴线转动时，第一活动件20与第一通道43的内壁面之间能够产生扭矩阻尼。扭矩阻尼能够传递至旋转的第一安装部21、第一部分上，用户与第一部分接触的部位能够感受到旋转阻力，利于控制第一部分的旋转。
其中需要说明的是，对于周向摩擦的扭矩阻尼形式，扭力值通常是恒定的，可以保持恒定的阻尼感。相对其他形式的扭矩机构，本申请的铰链组件100不易出现扭力值突变的情况。也就是说，采用周向摩擦形式的扭矩结构提供了稳定的扭力，在开合过程中的扭力大小保持一致，提升了用户的折叠体验。
由此，根据本发明实施例的电子设备的铰链组件100，通过第一安装部21与电子设备的第一部分连接，第二安装部31与电子设备的第二部分连接，实现电子设备的折叠和展开。并通过第一活动件20、第二活动件30和阻尼组件40相配合，提供了稳定的阻尼，在电子设备的折叠过程中实现折叠阻尼手感稳定，给电子设备用户带来更好的手感体验。
可选地，第一配合部41和第二配合部42可以是独立分开的，也可以是连接一体的。
根据本发明的一个实施例，如图13和图15所示，第一活动件20为第一柱状转轴，第一配合部41上设有第一通道43，第一通道43的内径小于第一柱状转轴的外径，阻尼组件40上设有与第一通道43连通的第一开口45，第一活动件20从第一通道43穿过，形成干涉过盈配合。需要说明的是，通过限定第一通道43的内径和第一柱状转轴的外径之间的相对大小关系，以及在阻尼组件40上开设第一开口45，能够实现对于第一柱状转轴的微弱干涉挤压，第一柱状转轴能够发生变形，阻尼组件40和第一柱状转轴之间会互相抱紧。当第一柱状转轴转动时，第一柱状转轴的外侧面和第一通道43的内壁面之间会互相摩擦形成阻尼感。
如图13和图15所示，第二活动件30为第二柱状转轴，第二配合部 42上设有第二通道44，第二通道44的内径小于第二柱状转轴的外径，阻尼组件40设有与第二通道44连通的第二开口46。第二活动件30的外侧面与第二通道44的内壁面之间互相摩擦形成阻尼感，在此不作赘述。
可选地，如图15和图17所示，第一开口45沿第一通道43的轴向贯通第一通道43，第一柱状转轴的轴向的各个位置受到的挤压力大小较为恒定，能够进一步提高第一柱状转轴和阻尼组件40之间的阻尼的稳定性。第二开口46沿第二通道44的轴向贯通第一通道43，同样能够提高第二柱状转轴和阻尼组件40之间的阻尼的稳定性。
在本发明的一些具体实施方式中，如图12所示，第一柱状转轴的外周面的一侧切边形成第一平面22，第一柱状转轴的截面为优弧弓形。第二柱状转轴的外周面的一侧切边形成第二平面32，第二柱状转轴的截面为优弧弓形。通过设置第一平面22能够减小第一柱状转轴的外周面和阻尼组件40之间的接触面积，从而减小第一柱状转轴和阻尼组件40之间的阻尼力。同样的，通过设置第二平面32能够减小第二柱状转轴和阻尼组件40之间的阻尼力。
根据本发明的一个实施例，如图2、图3、图8和图9所示，铰链组件100还包括传动件，传动件包括第一传动件50、第二传动件60和第三传动件70，第一传动件50设于第一活动件20且与第一活动件20同步活动，第二传动件60设于第二活动件30且与第二活动件30同步活动，第三传动件70设于支撑座10，第三传动件70与第一传动件50和第二传动件60配合，以使第一传动件50和第二传动件60同步活动。
例如，第一传动件50和第二传动件60可以通过齿轮或涡轮蜗杆或齿轮齿条连接形成传动关系，第三传动件70可位于第一传动件50和第二传动件60之间。
可选地，如图2和图3所示，第一传动件50和第二传动件60为平行设置的齿轮，第三传动件70为齿轮，且第三传动件70的轴线与第一传动件50和第二传动件60的轴线垂直。可选地，如图3所示，第一传动件50设有第一啮合齿，第二传动件60设有第二啮合齿，第一啮合齿相对于第一传动件50的轴线倾斜延伸，第二啮合齿相对于第二传动件60的轴线倾斜延伸。具体地，第一传动件50和第二传动件60通过斜齿齿轮结构传动 连接。第一传动件50和第二传动件60自带齿圈，齿圈可以是第一传动件50一体式加工成形的结构，也可以是通过拆件组装的方式实现的结构。
在本发明的一些具体实施方式中，如图8和图9所示，第一传动件50为第一传动齿轮，第二传动件60为第二传动齿轮。第一传动齿轮可以作为从动直齿轮，可以位于支撑座10靠近阻尼组件40的一侧。第三传动件70包括互相啮合的第三传动齿轮71和第四传动齿轮72，第三传动齿轮71与第一传动齿轮啮合，第四传动齿轮72与第二传动齿轮啮合。其中，第三传动件70设置在支撑座10上，支撑座10能够对第三传动件70起到支撑作用。
可选地，如图9所示，支撑座10包括支撑座主体11和从动齿轮座12，从动齿轮座12设于支撑座主体11邻近阻尼组件40的一侧，支撑座主体11和从动齿轮座12均可以支撑第一传动件50和第二传动件60。
根据本发明的一个实施例，如图9所示，第一传动齿轮、第二传动齿轮、第三传动齿轮71与第四传动齿轮72的轴线互相平行。利用齿轮转动的同步特定，能够保证第三传动齿轮71和第四传动齿轮72的齿轮运动同步。
可选地，如图9所示，第三传动齿轮71和第四传动齿轮72是直齿轮，当旋转第一活动件20或第二活动件30时，依靠齿轮啮合会驱使第三传动齿轮71和第四传动齿轮72转动。由于直齿轮的同步性，第三传动齿轮71和第四传动齿轮72按相同速度旋转，实现第一活动件20和第二活动件30旋转同步。又由于第一活动件20与第一壳体201连接，第二活动件30与第二壳体202连接，因此第一壳体201和第二壳体202能够达到同步旋转。在采用直齿轮的结构时，直齿轮加工相对斜齿轮加工较为简单，具有精度要求低和成本低等优点。
在本发明的一些具体实施方式中，如图1至图18所示，第一安装部21或第二安装部31还包括：铰链转动件和旋转连接件，铰链转动件设于第一活动件20或第二活动件30，旋转连接件分别与铰链转动件、电子设备的第一部分或第二部分、支撑座10连接。为了便于描述，将第一安装部21对应的铰链转动件定义为第一铰链转动件23，将第一安装部21对应的旋转连接件定义为第一旋转连接件24。并将第二安装部31对应的铰链 转动件定义为第二铰链转动件33，将第二安装部31对应的旋转连接件定义为第二旋转连接件34。
下面以第一安装部21为例进行说明。
如图1至图6所示，第一安装部21还包括第一铰链转动件23和第一旋转连接件24，第一铰链转动件23与第一活动件20连接，第一旋转连接件24分别与第一部分、第一铰链转动件23和支撑座10连接。
其中，第一铰链转动件23和第一旋转连接件24可以通过凸轮或齿圈或连杆连接，图1、图3、图8和图10中仅示意为凸轮连接。第一铰链转动件23和第一旋转连接件24的位置关系可以是上下层叠结构或前后排列结构，图1、图3、图8和图10中仅示意为前后排列结构。
如图9和图10所示，在支撑座主体11的上端面可设有弧形轨道13，第一旋转连接件24的左下端的一部分可以设于弧形轨道13内，且可以沿着弧形轨道13的壁面旋转，将该虚拟的旋转轴线定义为第一旋转轴25。也就是说，第一旋转连接件24围绕第一旋转轴25旋转。此时第一旋转连接件24可位于第一旋转轴25的下方。
如图9所示，第一铰链转动件23的前端可设有第一活动件20，第一铰链转动件23的后端左部分可以与第一旋转连接件24活动连接。第一活动件20可绕自身轴线旋转，也就是说，第一铰链转动件23在转动时，可以绕第一活动件20的轴线旋转。为了便于描述，将第一铰链转动件23的旋转轴心定义为第二旋转轴26，第一铰链转动件23能够围绕第二旋转轴26旋转，此时，第一铰链转动件23可以位于第一旋转轴25的下方。
同样的，将第二旋转连接件34的旋转轴心定义为第三旋转轴35，第二旋转连接件34能够围绕第三旋转轴35旋转，第二旋转连接件34位于第三旋转轴35的下方。并将第二铰链转动件33的旋转轴心定义为第四旋转轴36，第二铰链转动件33围绕第四旋转轴36旋转，第二铰链转动件33可位于第三旋转轴35的下方。
其中需要说明的是，如图10所示，第一铰链转动件23和第一旋转连接件24的轴心不同。具体地，第一旋转连接件24可以与弧形轨道13配合以实现限位且仅能作转动，当第一旋转连接件24以第一旋转轴25为中心在弧形轨道13中转动时，因为第一旋转连接件24和第一铰链转动件23 通过插销27连接，因此第一旋转连接件24能够伴随第一铰链转动件23转动，但第一铰链转动件23的转动中心为第二旋转轴26。需要说明的是，通过采用不同轴心的设计，使第一铰链转动件23的旋转中心可根据折叠屏的叠层灵活调整，良好解决了柔性屏折叠过程中存在的内应力问题，同时减少了褶皱感，提高了可折叠终端的可靠性，提升了用户使用体验。
可选地，如16至图18所示，第一壳体201和第一旋转连接件24可以通过机构方式连接成一体，例如螺钉、卡扣、焊接等方式。图16至图18中仅示意采用螺钉的连接方式，螺钉的连接数量不限。如图10所示，第一壳体201围绕第一旋转轴25旋转，第一旋转轴25位于第一壳体201的上方。
同样的，第二壳体202和第二旋转连接件34通过机构方式连接成一体，例如螺钉、卡扣、焊接等方式。图16至图18中仅示意用螺钉的连接方式，螺钉的连接数量不限。如图10所示，第二壳体202围绕第三旋转轴35旋转，第三旋转轴35位于第二壳体202的上方。
可选地，如图13所示，传动件和第一铰链转动件23及第二铰链转动件33呈偏心布局，也就是说，考虑到传动件与柔性屏折叠后的间隙，传动件和第一铰链转动件23及第二铰链转动件33呈偏心布局，传动件的中心在第一铰链转动件23和第二铰链转动件33的中心连线的下方。
需要说明的是，采用斜齿的传动机构，并采用偏心布局的方案，提升了齿轮的重合度，进而提升了第一壳体201和第二壳体202折叠过程的同步性，也降低了铰链组件100的厚度尺寸，实现了轻薄化设计。
可选地，如图1所示，阻尼组件40可以固定在支撑座10或壳体上保持不动，第一铰链转动件23的轴心围绕第一配合部41旋转并通过干涉产生摩擦力形成扭矩。同样的，第二铰链转动件33的轴心也可以围绕第二配合部42旋转并通过干涉产生摩擦力形成扭矩。
可选地，第一铰链转动件23和第一旋转连接件24之间可以通过插销27相连接，插销27可以保证第一铰链转动件23和第一旋转连接件24同步活动。具体地，如图9所示，在第一旋转连接件24的前端设有弧形槽28，第一铰链转动件23的后端设有配合槽29，插销27的后端插接至弧形槽28内，插销27的前端插接至配合槽29内。需要说明的是，插销27的 前端可以与第一铰链转动件23固定连接，插销27的后端可以与第一旋转连接件24活动连接，插销27可以沿着弧形槽28的延伸方向活动。
可选地，如图2所示，可以通过卡簧实现插销27与第一铰链转动件23之间的连接，防止插销27脱落。具体地，配合槽29为通槽，插销27的前端穿过通槽。卡簧位于通槽的外侧，通过卡簧能够将插销27固定在通槽内。
可选地，通过插销27、第一旋转连接件24和第一铰链转动件23相配合，能够将第一旋转连接件24的转动传递至第三传动齿轮71。
可选地，如图1所示，第一旋转连接件24的一部分可以做成平面，促使电子设备的其他部件能够嵌在第一旋转连接件24上。在第一旋转连接件24转动时，其他固定在第一旋转连接件24上的零件可以随着一起转动。
需要说明的是，第二安装部31与第一安装部21结构相同，且能达到相同的技术效果，为避免重复，这里不再赘述。
本发明还提供了一种电子设备，包括柔性屏幕、第一部分、第二部分和上述任一实施例的铰链组件100。电子设备包括第一部分和第二部分，第一部分与第一安装部21连接，第二部分与第二安装部31连接，柔性屏幕覆盖第一部分、铰链组件100和第二部分。
第一部分可以包括第一壳体201，第二部分可以包括第二壳体202。铰链组件100的数量可以为两组，两组铰链组件100可以分别放置于电子设备的折叠轴线方向的两侧，同时铰链组件100可以位于可折叠屏幕的下方。需要说明的是，铰链组件100的数量不限于两组，还可以是多组。图16至图18中仅仅示意了两组铰链组件100。
需要说明的是，本发明的实施例仅仅示意说明了U型折叠终端，而三折、多层折叠终端也可以才采用本申请实施例的铰链组件100。
根据本发明实施例的电子设备的其他构成例如柔性屏等以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本 发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
