结合图2，一种实施方式中，第二铰链节204上盖设有固定板704，固定板704通过螺钉等紧固件固定在第二铰链节204上，并且固定板704覆盖滑动导槽2446，伸出部2440收容于滑动导槽2446与固定板702形成的收容空间，因此伸出部2440仅具有沿滑动导槽2446滑动的自由度。
本实施例中，第三转动杆242设有第四联动齿轮508a，第二铰链节204设有对应第四联动齿轮508a的第四联动齿条508b。第四联动齿轮508a为以第三转动杆242的转轴为中心轴的齿轮，即第四联动齿轮508a的转动轴与第三转动杆242的转动轴重合，第四联动齿条508b为直线型的齿条。

铰链装置200由展开状态至折弯状态的过程如下：
当使第一铰链节202相对第三铰链节206转动的外力施加于第一铰链节202上时，第一铰链节202与第二转动杆224相对滑动，同时，第三联动齿轮506a与第三联动齿条506b啮合，第三联动齿轮506a在第三联动齿条506b上滚动，从而带动第一铰链节202和第二转动杆224相对第一转动杆222转动；第二转动杆224转动，第一联动齿轮502a转动，第一联动齿轮502a与第一联动齿条502b啮合，由于第一转动杆222与第三铰链节206的滑动连接关系，第一联动齿轮502a在第一联动齿条502b上滚动的同时，第二转动杆224带动第一转动杆222在第三铰链节206上向靠近第三铰链节206的方向滑动，进一步的，第一转动杆222和第三转动杆242通过联动机构400的活动连接，联动机构400使第三转动杆242的运动方向与第一转动杆222的运动方向反向且同步，具体的，结合第三转动杆242与第三铰链节206的滑动连接关系，第一转动杆222在第三铰链节206上向靠近第三铰链节206的方向滑动，通过联动机构400作用，第三转动杆242在第三铰链节206上向靠近第三铰链节206的方向滑动，进一步的，第三转动杆242带动第四转动杆244在第三铰链节206上向靠近第三铰链节206的方向滑动，此时，第三联动齿轮506a与第三联动齿条506b啮合，第三联动齿轮506a在第三联动齿条506b上滚动，从而第四转动杆244转动；第四转动杆244转动的同时，第四转动杆244与第二铰链节204相对滑动，同时，第四联动齿轮508a与第四联动齿条508b啮合，第四联动齿轮508a在第四联动齿条508b上滚动，从而第二铰链节204随第四转动杆244相对第三铰链节206转动。铰链装置200由折弯状态至展开状态的过程与上述过程相反。
本实施例中，第二联动齿轮504a与第二联动齿条504b的配合将第一铰链节202相对第三铰链节206的转动和滑动相互转化，第四联动齿轮508a与第四联动齿条508b的配合将第二铰链节204相对第三铰链节206的转动和滑动相互转化，从而使第一铰链节202和第二铰链节204的转动、滑动运动结合并同时发生。进一步的，通过联动机构400的作用，第一铰链节202和第二铰链节204可以同步、反向滑动及转动。

本申请实施例中，联动机构400用于使第一铰链节202和第二铰链节204相对第三铰链节206同步、相反的运动。联动机构400包括但不限于以下几种实施方式：
实施方式一
请一并参阅图13至图16，图13为铰链装置200的俯视图，图14为图13的A位置放大示意图，图15为铰链装置200展开时的立体图，图16为铰链装置200弯折时的立体图。联动机构400包括联动杆600，联动杆600包括相对设置的第一端部62和第二端部64，以及位于第一端部62和第二端部64之间的连接部66，连接部66转动连接第三铰链节206，第一端部62活动连接至第一转动杆222，第二端部64活动连接至第三转动杆242。当第一转动杆222向靠近第三铰链节206方向滑动时，第一转动杆222推动第一端部62，以使联动杆600绕连接部66以图示的顺时针方向转动，从而第三转动杆242随第二端部64也向靠近第三铰链节206方向滑动，第一铰链节202相对第三铰链节206的滑动运动与第一转动杆222相同，第二铰链节204相对第三铰链节206的滑动运动与第三转动杆242相同，从而实现了第一铰链节202和第二铰链节204的同步、反向滑动。进一步的，受到前述第一转动组件22和第二转动组件24的作用，还实现了第一铰链节202和第二铰链节204的同步、反向转动。
本实施例中，第一转动杆222上设有第一导向块2220，第三转动杆242上设有第二导向块2420，第一导向块2220活动连接第一端部62，第二导向块2420活动连接第二端部64，第三铰链节206设有滑轨2060，第一导向块2220和第二导向块2420经滑轨2060滑动连接第三铰链节206。进一步的，滑轨2060为沿直线延伸的滑轨2060，第一导向块2220和第二导向块2420的滑动轨迹为直线，因此可以理解为，第一转动杆222和第三转动杆242可以在第一铰链节202上滑动。
本实施例中，第一端部62设有第一滑槽62a，第二端部64设有第二滑槽64a，第一导向块2220设有第一凸起62b，第二导向块2420设有第二凸起64b，第一凸起62b于第一滑槽62a内活动连接第一端部62，第二凸起64b于第二滑槽64a内活动连接第二端部64。具体的，第一滑槽62a和第二滑槽64a为长条形的滑槽，第一凸起62b和第二凸起64b为圆柱体。第一凸起62b可以在第一滑槽62a内沿第一滑槽62a的长度方向滑动，也可以相对第一端部62转动；第二凸起64b可以在第二滑槽64a内沿第二滑槽64a的长度方向滑动，也可以相对第二端部64转动。因 此，第一导向块2220和第二导向块2420在第三铰链节206的上滑动可以与联动杆600的转动相互转换。
具体到图15和图16，铰链装置200由展开状态至折弯状态的过程如下：
第一铰链节202相对第三铰链节206转动，第一转动杆222向靠近第三铰链节206方向滑动，第一转动杆222推动第一端部62，以使联动杆600绕连接部66以图示的顺时针方向转动，从而第三转动杆242随第二端部64也向靠近第三铰链节206方向滑动，第二铰链节204相对第三铰链节206转动。铰链装置200由折弯状态至展开状态的过程与上述过程相反，从而实现了第一铰链节202和第二铰链节204的同步、反向滑动。
本实施例中，第一端部62和第二端部64对称设置，联动杆600的转动轴位于连接部66上，且该转动轴位于联动杆600的几何中心，当联动杆600绕该转动轴转动时，活动连接于第一端部62的第一导向块2220与活动连接于第二端部64的第二导向块2420的运动过程及运动轨迹绕该转动轴轴对称，从而第一铰链节202和第二铰链节204滑动的距离始终相同，滑动的方向始终相反，进一步的，第一铰链节202和第二铰链节204的运动过程始终对称、同步。
本实施例中，当铰链装置200处于展开状态时，第一凸起62b抵接于第一滑槽62a远离连接部66的一端的侧壁，第二凸起64b抵接于第二滑槽64a远离连接部66的一端的侧壁，从而限制第一凸起62b和第二凸起64b的运动行程，进一步的，当第一凸起62b抵接至第一滑槽62a远离连接部66的一端的侧壁，第二凸起64b抵接至第二滑槽64a远离连接部66的一端的侧壁时，第一凸起62b和第二凸起64b无法继续滑动，对应的，第一转动组件22和第二转动组件24无法继续转动，第一铰链节202和第二铰链节204无法继续相对第三铰链节206转动，防止第一铰链节202和第二铰链节204过渡转动而出现向外翻折的情况，保护铰链装置200及柔性显示屏300。进一步的，第一滑槽62a和第二滑槽64a的长度尺寸满足当铰链装置200处于展开状态时，第一凸起62b及第二凸起64b的滑动行程正好使第一铰链节202和第二铰链节204完全展开且不出现外翻。
一种实施方式中，联动杆600活动连接一个第一导向块2220与一个第二导向块2420形成联动组件，联动组件的数量为多个。具体的，联动组件的数量可以为偶数个，并且多个联动组件对称设置于第三铰链节206的长度方向的两端，联动组件均匀分布，从而提高第一铰链节202和第二铰链节204的联动效果。进一步的，联动组件的数量越多，第一铰链节202和第二铰链节204的联动效果越好。
联动杆600两端活动连接至第一铰链节202和第二铰链节204的方式简单易实现，结构零件少，实现效果好，安装、拆卸、维护方便。
结合图2，一种实施方式中，第三铰链节206上还盖设有盖板706，盖板706盖设于联动机构400上，盖板706通过螺钉等紧固件固定在第一铰链节202上。 一方面，盖板706用于遮挡联动机构400，放置联动机构400露出而与其他结构干涉，另一方面，盖板706转动连接联动杆600的连接部66，从而将联动杆600安装于盖板706与第三铰链节206之间，固定联动杆600的转动轴。事实上，盖板706还可以覆盖第一导向块2220和第二导向块2420，使第一导向块2220和第二导向块2420只能沿滑轨2060滑动。

一种实施方式中，联动杆600的数量可以为两个，两个联动杆600于连接部66相互转动连接，从而两个联动杆600均可以转动连接第三铰链节206。进一步的，两个联动杆600对称设置，两个联动杆600的运动方式同步且相反。
实施方式四
请参阅图19，图19为铰链装置200的立体图。联动机构400包括齿轮800，齿轮800转动连接于第三铰链节206上，第一转动杆222上设有第一齿条802，第三转动杆242上设有第二齿条804，第一齿条802与第二齿条804分别位于齿轮800的相对的两侧，且均与齿轮800啮合。具体的，齿轮800的转动轴垂直于第三铰链节206，第一齿条802和第二齿条804的滑动方向相反，例如，齿轮800顺时针转动时，第一齿条802和第二齿条804相向运动，齿轮800逆时针转动时，第一齿条802和第二齿条804相背运动。
本实施例中，第三铰链节206设有滑轨2060，第一齿条802和第二齿条804经滑轨2060滑动连接第三铰链节206。进一步的，滑轨2060为沿直线延伸的滑轨2060，第一导向块2220和第二导向块2420的滑动轨迹为直线，因此可以理解为，第一转动杆222和第三转动杆242可以在第一铰链节202上滑动。
铰链装置200由展开状态至折弯状态的过程中，第一齿条802向靠近第三铰链节206的方向滑动，由于第一齿条802与齿轮800的啮合，齿轮800与第二齿条804的啮合，第二齿条804也同步向靠近第三铰链节206的方向滑动。
请参阅图6和图7，本申请实施例提供的铰链装置200还包括阻尼组件，阻尼组件设置于第一转动组件22及第二转动组件24上，以提供阻尼力矩。具体的，阻尼组件包括依次套设于第一转动杆222或第四转动杆244两端的摩擦片、弹性圈及螺栓，通过调节螺栓的锁紧程度，改变弹性圈、摩擦片及第一转动杆222或第四转动杆244之间的摩擦力，从而改变阻尼力矩的大小，使第一转动组件22和第二转动组件24的转动手感更佳。
请参阅图1，本申请实施例还提供一种电子装置100，包括柔性显示屏300和铰链装置200，柔性显示屏300的两个非折弯区域300b分别安装于第一铰链节202和第二铰链节204上，可折弯区域300a位于第三铰链节206上，从而可以通过第一铰链节202、第二铰链节204相对第三铰链节206的折弯或展开实现柔性显示屏300的折弯或展开。
