每一所述第二支架12包括平坦的顶面1201、两相对的第一侧面1202和两相对的第二侧面1203，且所述两第二侧面1203为所述第二支架12所在长度方向的对侧面。所述第二支架12的顶面1201的边缘沿其长度方向开设开口121，并且在所述第二支架12的开口121处形成长条形的凸缘122。每一所述开口121贯穿所述第二支架12的其中一个第一侧面1202及其中一个所述第二侧面1203。
可以理解的，所述支架10的数量根据所述柔性铰链20的数量来设定，并用于支撑所述柔性铰链20，且能将所述柔性铰链20固定在预设位置。
请参阅图2-3，每一所述柔性铰链20包括第一链节组件3、两第二链节组件4和若干锁固件5。所述两第二链节组件4分别设置在所述第一链节组件3两侧，且与所述第一链节组件3固定连接。所述若干第一链节组件3相对所述两第二链节组件4活动时带动所述铰链装置100发生形变。
请一并参阅图2和图3，在本实施例中，每一所述第一链节组件3包括相互铰接的若干第一链板31、若干第二链板32和两相对的第三链板33。所述若干第一链板31和所述若干第二链板32通过所述第三链板33与所述第一支架11和所述第二支架12连接，且所述第一链板31与所述第二链节组件4固定连接，从而实现所述第一链节组件3与所述第二链节组件4的固定连接。所述若干第一链板31、所述若干第二链板32及所述两第三链板33均对齐而呈线性排列。每一所述第一链板31和每一所述第二链板32并排且错开铰接，也即相邻的第一链板31之间和相邻的第二链板32之间均隔开设置。
可以理解的，在本实施例中，如图2所示，每一所述第一链节组件3关于本身的中心线对称。所述第一链节组件3的中心线包括平行于所述第一链节组件3所在长度方向的第一中心线X和垂直于所述第一中心线X的第二中心线Y，因此所述铰链装置100发生形变时受力较均衡，且能够形成弯曲成规则的形状。

可以理解的，在其他实施例中，所述支架10可设置安装结构以固定或可活动的连接在所述柔性铰链20上。这里的安装结构分为固定连接部和/或活动连接部。例如，通过所述固定连接部将所述第三链节头43固定设置在所述支架10上，所述固定连接部例如是，但不局限有锁固件(如螺钉)。通过所述活动连接部连接可以是滑动引导结构、磁性吸附结构等。

可以理解地，所述第三活动件43也可以和第一活动件41的结构相同，即都具有左右对称式的结构，所述第一支架11和所述第二支架12相应地设置与所述第一活动件43固定的结构即可。在这种情况下，所述第三活动件43即为所述第一活动件41，或者所述第一活动件41也可看成所述第三活动件43。
还可以理解地，所述限位件44也并不限于上述独立的元件，而是可以为所述第二活动件42的一部分，即所述第二活动件42可以包括限位件44。进一步地，所述限位件44也不限于销钉或螺钉的结构，而是可以一体形成于所述第二活动件上，比如卡扣或挡板的结构。
还可以理解地，所述第二活动件42与所述第一活动件41的活动连接也不限于上述方式，而是可以包括其他各种活动连接方式，比如可以通过螺钉枢接、通过滑轨滑动连接、通过弹簧弹性连接等。
