在其他实施例中，定位件223上的两个所述第一导滑条2237可以省略；滑动件40上与所述定位件223的两个第一导滑条2237对应的两个所述第一导滑槽422也可省略。即，所述铰节的两个连接部是分别设置于两个所述滑动空间内的第二导滑条2257，即，两个所述连接部是设于所述夹持件225上的两个所述第二导滑条2257；所述铰节的滑动件40的每一滑动部420是开设于所述滑动板42并与所述第二导滑条2257对应的第二导滑槽424，即，每一滑动部420沿对应的第二导滑条2257滑动。

请一并参阅图7及图8，示出了本申请第一实施例的铰节组合而成的铰链。本申请铰链300包括若干个所述铰节100依次相连接，其中，位于所述铰链300中部的每一铰节100的滑动件40的两个所述滑动部420分别连接于相邻的两个所述铰节100的连接机构22的连接部221，即，每一个连接机构22的两个连接部221上均连接有一个所述滑动件40，两个所述滑动件40分别位于所述连接机构22上的锁固件226相反的两侧，因此，两个所述滑动件40相对于所述连接机构22旋转的旋转轴分别位于所述锁固件226相反的两侧。所述铰链300的两端部分别设置一滑动件40a，每一滑动件40a的结构与位于所述铰链中部的滑动件40的结构相似，不同之处在于，所述滑动件40a是在滑动件40的基础上省略了一个滑动部420，且在滑动件40a上背朝滑动部420的一侧凸设一连接板44a，所述连接板44a用于连接外部元件。组装所述铰链300时，先将每一铰节100的连接装置20完成，即，将每一铰节100的连接杆2261依次穿过所述夹持件225的第二定位孔2254、所述定位件223的第一定位孔2234，以及所述弹性件228后螺接于所述螺母2263，至所述弹性件228弹性抵推所述定位件223，使所述止挡块2238紧贴于所述止挡块2258，所述定位件223的延伸柱2239紧贴所述夹持件225的延伸柱2259。再将每一铰节100的滑动件40的其中一滑动部420连接至其中一连接装置20的其中一连接部222，将所述滑动件40的另一滑动部420连接至相邻的另一个连接装置20的连接部222上即可。此时，所述铰链300上的每一个铰节100的滑动件40与连接装置20能相对转动，从而能实现所述铰链300的弯曲，由于每一个铰节100的滑动件40与连接装置20之间有摩擦力，从而所述铰链300在弯曲的过程中有阻尼的效果。
使用时所述铰链300时，将所述铰链300通过两个所述连接板44a连接至待弯曲的元件上，也可以将每一铰节100的滑动件40的连接孔443连接至待弯曲的元件上即可。
请一并参阅图9至图12，示出了本申请第二实施例的铰节。本申请第二实施例的铰节与第一实施例的铰节相似，所述第二实施例与第一实施例的不同之处在于：第二实施例中的连接装置与第一实施例中的连接装置结构不同。在第二实施例中，铰节100a包括一连接装置20a及滑动件40，所述第二实施例中的铰节100a的滑动件40的结构与第一实施例中的铰节100的滑动件40的结构相同。所述连接装置20a包括一连接机构22a、一连接柱24、一连接轴26，以及一连接片28。所述连接机构22a是将第一实施例中的连接机构22的定位件223与夹持件225一体成型制成，即，将所述第一实施例中的所述定位件223的止挡块2238与所述夹持件225的止挡块2258连接于一体就形成第二实施例中的连接机构22a。所述连接机构22a包括定位件223a、连接件225a 及连接于所述定位件223a与所述连接件225a的连接块229，所述定位件223a的结构与第一实施例中的定位件223的结构相同，所述连接件225a的结构与第一实施例中的夹持件225的结构相同，所述连接块229是将第一实施例中的止挡块2238、2258结合于一体。所述定位件223a、连接件225a及连接块229共同围成两个滑动空间2210，每一滑动空间2210的宽度大于或等于滑动件40的滑动板42的厚度。所述定位件223a背朝所述连接件225a的侧面的中部开设有一连接孔2230，所述连接孔2230用于连接所述连接柱24。所述连接机构22a设置有相对的两个连接部221，两个所述连接部221对称设置，即，两个所述连接部221沿所述连接孔2230的轴心线对称。所述连接件225a上的两个所述第二导滑条2257对称设置，即，两个所述第二导滑条2257沿所述连接孔2230的轴心线对称；所述定位件223a上的两个所述第一导滑条2237对称设置，即，两个所述第一导滑条2237沿所述连接孔2230的轴心线对称。每一滑动空间2210内的第一导滑条2237与第二导滑条2257对应，每一连接部221包括位于同一滑动空间2210内的所述第一导滑条2237及所述第二导滑条2257。所述连接片28是条形片，所述连接片28的一端开设有一连接孔282，所述连接片28的另一端开设有一导滑孔284，所述导滑孔284是朝向所述连接孔282延伸的条形孔，即，所述导滑孔284沿所述连接片28的长度方向延伸。
组装所述铰节100a时，将所述连接柱24的一端固定于所述连接机构22a的连接孔2230内；将所述连接轴26的一端固定于所述滑动件40的连接孔443内；将所述滑动件40的其中一滑动部420***所述连接机构22a的其中一滑动空间2210内，使所述其中一滑动空间2210内的第一导滑条2237及第二导滑条2257分别滑动地收容于所述其中一滑动部420的第一导滑槽422及第二导滑槽424内。此时，所述连接柱24与所述连接轴26位于所述铰节100a的同一侧。再将所述连接片28的连接孔282连接于所述连接轴26上，所述连接片28的导滑孔284连接于所述连接柱24上。所述连接轴26与所述连接片28的连接孔282是过盈配合；所述连接柱24与所述导滑孔284是活动连接，即，所述连接柱24能在所述导滑孔284内滑动和转动。
滑动所述铰节100a的滑动件40时，所述滑动件40的滑动部420相对于对应的连接部221滑动，即，所述滑动部420的第一导滑槽422及第二导滑槽424沿所述连接部221上对应的第一导滑条2237及第二导滑条2257滑动，从而所述滑动件40绕第一导滑条2237或第二导滑条2237的圆弧的圆心转动，使所述滑动件40相对于所述连接机构22a能转动，且能止挡于所述连接块229。当所述滑动件40转动至止挡于所述连接块229时，所述滑动件40的顶面与所述连接机构22a的顶面齐平。由于所述铰节100a的连接轴26与所述连接片28的连接孔282是过盈配合，所述连接柱24与所述导滑孔284是活动连接，因此，在所述滑动件40滑动的过程中，所述连接柱24沿所述连接片28的导滑孔284滑动，连接柱24同时抵接连接片28，驱动连接片28相对连接轴26 转动，即所述连接轴26在所述连接孔282内转动，所述连接轴26与所述连接孔282的内表面之间产生摩擦力，从而所述铰节100a的滑动件40在弯曲的过程中有阻尼的效果。
请参考图13，图13是本申请提供的第二实施例的铰节组合成的铰链的立体结构分解示意图。铰链300a包括若干个所述铰节100a依次相连接，即，每两个相邻的铰节100a通过所述连接片28相连接。具体组装如下：将其中一个铰节100a的滑动件40的滑动部420***另一个铰节100a的连接机构22a的滑动空间2210内，使所述滑动空间2210内的第一导滑条2237及第二导滑条2257分别滑动地收容于所述滑动部420的第一导滑槽422及第二导滑槽424内；再将连接片28的连接孔282连接于所述其中一个铰节100a的连接轴26上，所述连接片28的导滑孔284连接于所述另一个铰节100a的连接柱24上，所述连接轴26与所述连接片28的连接孔282是过盈配合，所述连接柱24与所述导滑孔284是活动连接。所述铰链300a上的每一个铰节100a的滑动件40与相应的连接机构22a能相对转动，从而能实现所述铰链300a的弯曲，并且由于每一个铰节100a的连接轴26与所述连接片28的连接孔282是过盈配合，因此，所述铰链300a在弯曲的过程中有阻尼的效果。
本申请的铰链发生的弯曲可以从直线的形态变成圆弧的形态。当在直线的形态时，铰链整体铺展开，从而方便用户展开待弯曲的元件。当在圆弧的形态时，待弯曲的元件整体卷曲而方便用户收纳。当然，铰链的弯曲所切换的形态也可以根据需求变化，以适应更多应用场合的需求。比如从拱形切换成圆环形、从平板形切换成波浪形、从U形切换成S形等等。
本申请的铰链可以运用至各种需要弯曲的电子产品、机构设备上。
以上所述是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
