具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图 时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
在相关技术中，现有的折叠屏铰链结构往往组装复杂并且折叠后铰链结构中的支撑件容易浮起导致屏幕不平整，影响显示屏的使用体验。并且具有折叠屏的电子产品往往采用单角度折叠设计，即铰链结构只能带动一侧屏幕转动，受限于折叠屏的最小折叠半径，导致折叠后的屏幕无法完全贴合，中间留有较大的楔形空隙。
为了解决上述技术问题，根据本公开的实施例提供一种铰链结构。
本公开提供的铰链结构包括：基架组件，基架组件包括第一支撑面；支撑组件，支撑组件包括第二支撑面，所述第一支撑面和所述第二支撑面用于承载显示屏幕等功能模组或功能组件；第一转动组件，第一转动组件与基架组件转动连接；第二转动组件，第二转动组件与基架组件转动连接，第二转动组件与支撑组件滑动连接；以及连杆组件，连杆组件分别与支撑组件、第一转动组件和第二转动组件铰接。
其中，第一支撑面和第二支撑面用于承载显示屏幕等功能模组，接下来以第一支撑面和第二支撑面承载显示屏幕为例，可以分为以下情形：
情形一：支撑组件可以相对基架组件向朝向显示屏幕一侧折叠或向背离显示屏幕一侧展开，此种情形可以理解为内折方式；
此时，支撑组件包括折叠状态和展开状态，当支撑组件处于折叠状态时，第一支撑面和第二支撑面围合成容屏空间，显示屏幕位于容屏空间内；当支撑组件处于展开状态时，第一支撑面和第二支撑面位于同一平面，第一支撑面和第二支撑面用于共同承载显示屏幕。
情形二：支撑组件可以相对基架组件向背离显示屏幕一侧折叠或向朝向显示屏幕一侧展开，此种情形可以理解为外折方式；
此时，支撑组件包括折叠状态和展开状态，当支撑组件处于折叠状态时，显示屏幕围绕设置在第一支撑面和第二支撑面外，当支撑组件处于展开状态时，第一支撑面和第二支撑面位于同一平面，第一支撑面和第二支撑面用于共同承载显示屏幕。
根据本公开的设置，通过连杆组件、第一转动组件、第二转动组件共同带动支撑组件进行转动并且通过设置限位件对支撑件转动时进行限位作用。使得支撑组件的运动精度更高，使屏幕折叠更为自然，有效保护屏幕，使支撑组件对屏幕提供有效支撑的同时不会产生浮起现象，屏幕更为平整。
可以理解的是，本公开所涉及的铰链结构可以适用于以下所列的任意一种终端中。
可以理解的是，本公开中涉及的终端，也可以称为终端设备、用户设备(User  Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信***时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
图1是根据一示例性实施例示出的一种铰链结构的结构示意图。图2是根据一示例性实施例示出的一种铰链结构的单边结构***示意图。图3是根据一示例性实施例示出的一种处于展开角度的铰链结构的结构示意图。图4是根据一示例性实施例示出的一种折叠过程中的铰链结构的结构示意图。图5是根据一示例性实施例示出的一种处于折叠角度的铰链结构的结构示意图。
在一些实施例中，如图1至图5所示，铰链结构包括基架组件20、支撑组件30、第一转动组件40、第二转动组件50和连杆组件。其中，基架组件20可以与第一转动组件40转动连接，基架组件20还可以与第二转动组件50转动连接，支撑组件30可以与第一转动组件40铰接，并且支撑组件30可以与第二转动组件50滑动连接。支撑组件30还可以与连杆组件铰接。基架组件20可以提供转动支点，使得第一转动组件40、第二转动组件50和连杆组件可以绕基架组件20相对转动。支撑组件30可以通过第一转动组件40、第二转动组件50和连杆组件与基架组件20转动连接。
在一些实施例中，支撑组件30可以与基架组件20转动连接，支撑组件30可以设置于基架组件20的两侧，并且支撑组件30可以绕基架组件20转动，例如，图3至图4，支撑组件30可以绕平行于Y轴方向的轴转动。需要说明的是，Y轴方向可以为支撑组件30的长度方向或宽度方向。
在一些实施例中，支撑组件30可以绕基架组件20相向转动或相背转动，使得支撑组件30可以在折叠状态和展开状态间切换。
在一些实施例中，基架组件20可以在X轴方向和Y轴方向所构成的平面上延伸，例如在X轴方向和Y轴方向所构成的平面上可以是矩形形状。但本公开不限于此，基架组件20也可以是其他多边形形状，或者圆形、椭圆形形状。
在一些实施例中，支撑组件30可以在X轴方向和Y轴方向所构成的平面上延伸，例如在X轴方向和Y轴方向所构成的平面上可以是矩形形状。但本公开不限于此，支撑组件30也可以是其他多边形形状、圆形或椭圆形形状。
在一些实施例中，基架组件20包括第一支撑面24，支撑组件30包括第二支撑面33，例如，可以包括间隔基架组件20相对设置的一对第二支撑面33.例如，如图3所示，第一支撑面24可以是在Z轴方向上的上表面。Z轴方向可以是铰链结构的厚度方向，当铰链结构用于电子设备时，Z轴方向也可以是电子设备的厚度方向。当铰链结构用于电子设备时，第一支撑面24和第二支撑面33用于支撑电子设备的显示屏幕。
需要解释的是，支撑组件30处于折叠状态时，支撑组件处于第一锁止位置，即支撑组件30相对于基架组件20处于完全展开状态，第一支撑面和第二支撑面位于同一平面，第一支撑面和第二支撑面用于共同承载展开状态的屏幕。支撑组件30处于折叠状态时，支撑组件处于第二锁止位置，即支撑组件30相对于基架组件20处于完全折叠状态。可以理解的是，当支撑组件以内折方式相对基架组件折叠，第一支撑面相对于第二支撑面呈倾斜设置，第一支撑面和第二支撑面围合成容屏空间，显示屏幕位于容屏空间内，容屏空间用于容纳并保护显示屏幕。当支撑组件以外折方式相对基架组件折叠，显示屏幕围绕设置在第一支撑面和第二支撑面背离基架一侧。
在一些实施例中，当第一支撑面24与第二支撑面33位于同一平面时，支撑组件30处于展开状态。
在一些实施例中，当支撑组件30处于展开状态时，支撑组件30通过绕基架组件20相向转动可以切换至折叠状态。当支撑组件30处于折叠状态时，支撑组件30通过绕基架组件20相背转动可以切换至展开状态。
在一些实施例中，当支撑组件30处于折叠状态时，第一支撑面24和第二支撑面33之间可以形成容置空间，可以用于容纳其他的部件，并且对该部件提供支撑作用。
在一些实施例中，当铰链结构用于电子设备时，第一支撑面24和第二支撑面33可以合围成容屏空间，容屏空间的横截面形状可以为水滴形或U形等。水滴形的容屏空间更为符合柔性屏幕的折弯性能，对柔性屏幕有保护效果，可以延长柔性屏幕的使用寿命。
在一些实施例中，位于基架组件20两侧的第二支撑面33可以相对靠近，使得铰链结构呈折叠状态。当位于基架组件20两侧的第二支撑面33靠近为最小距离时，可以认为铰链结构呈完全折叠状态，例如图5所示的状态。当位于基架组件20两侧的第二支撑面33之间的距离大于最小距离时，可以认为铰链结构处于折叠过程中，其可以具有图4所示的状态。
在一些实施例中，当支撑组件30处于折叠状态时，第一支撑面24和第二支撑面33可以呈倾斜设置，并且第二支撑面33的倾斜方向与支撑组件30的折叠方向相同。
在一些实施例中，第一转动组件40的第一端可以与基架组件20转动连接，第一转动 组件40的第二端可以与支撑组件30铰接。其中，第一转动组件40的第一端为第一转动组件40靠近基架组件20的一端，第一转动组件40的第二端为第一转动组件40远离基架组件20的一端。
在一些实施例中，第二转动组件50的第一端可以与基架组件20转动连接，第二转动组件50的第二端可以与支撑组件30滑动连接。其中，第二转动组件50的第一端为第二转动组件50靠近基架组件20的一端，第二转动组件50的第二端为第二转动组件50远离基架组件20的一端。
在一些实施例中，连杆组件分别可以与支撑组件30、第一转动组件40和第二转动组件50铰接。例如，如图1所示。连杆组件可以绕支撑组件30铰接轴转动，连杆组件可以与第一转动组件40沿Y轴方向同轴铰接，连杆组件还可以与第二转动组件50也沿Y轴方向同轴铰接。
在一些实施例中，连杆组件可以包括第一连杆71和第二连杆72。第一连杆71和第二连杆72可以位于支撑组件30的靠近基架组件20的一侧。但是本公开不限于此，连杆组件还可以设置多个连杆。本公开利用多个连杆可以使支撑组件30在转动过程中运动更为精准，并且使得第一支撑面24和第二支撑面33合围的容屏空间得边缘曲率不同，并且使折叠处过度缓和，使得铰链结构可以适用于一些具有柔性的部件。例如可以适用于柔性屏幕，进而减少柔性屏幕的折叠痕迹。
在一些实施例中，支撑组件30可以包括支撑件31和固定件32。支撑件31和固定件32可以位于基架组件20的两侧。支撑件31可以与第一转动组件40和连杆组件铰接，使得支撑件31可以在第一转动组件40和连杆组件的带动下绕基架组件20稳定转动。固定件32与第二转动组件50滑动连接，固定件32还与连杆组件铰接，使得固定件32可以在第二转动组件50和连杆组件的带动下绕基架组件20稳定转动。支撑件31设置有第二支撑面33，例如，如图3所示。第二支撑面33可以是在Z轴方向上的上表面。Z轴方向可以是铰链结构的厚度方向，当铰链结构用于电子设备时，Z轴方向也可以是电子设备的厚度方向。
在一些实施例中，支撑件31用于为显示屏幕等功能模组提供支撑面以承载显示模组等，支撑件31为板状结构、块状结构或条状结构等。但本公开不限于此，也可以是其他楔形结构、块状结构或圆柱结构。支撑件31用于为铰链结构提供支撑结构，固定件32可以为支撑件31提供支撑和固定作用。以折叠形式为内折为例，支撑件31与固定件32间的转动连接关系可以在支撑组件处于折叠状态时，使得支撑件31可以倾斜于Z轴方向，进而使得容屏空间在X轴和Y轴形成的平面的截面形状可以呈现水滴形或U形等具有倾斜 边缘的形状。
第二转动组件50的第二端能够在固定件32内滑动，使得当支撑组件30的固定件32进行转动时，第二转动组件50保持与固定件32的连接的同时，还可以使得支撑组件30的转动轨迹避免受到第二转动组件50的长度的限制，从而使得支撑组件30顺利完成转动动作。
可以理解的是，在支撑组件30的支撑件31相对基架组件20折叠或展开的过程中，第二转动组件50可以相对固定件32滑动，进而带动支撑件31和固定件32沿滑动方向滑动。支撑组件30的支撑件31相对基架组件20折叠过程中，支撑件31和固定件32沿滑动方向朝向基架组件一侧滑动，支撑组件30的支撑件31相对基架组件20展开过程中，支撑件31和固定件32沿滑动方向朝向背离基架组件一侧滑动。在铰链结构折叠或展开过程中，通过支撑件31和固定件32沿滑动方向滑动以更好适应显示屏幕，以起到保护显示屏幕的作用，进而来延长显示屏幕的寿命。
在一些实施例中，第一连杆71的第一端与支撑件31铰接，第一连杆71的第二端与固定件32铰接。第一连杆71通过两个铰接关系将支撑件31的靠近基架组件20的一侧和固定件32的靠近基架组件20的一侧连接，又使支撑件31和固定件32有一定活动空间，可以进行相对转动。例如，如图1所示。其中，第一连杆71的第一端为第一连杆71在X轴方向上靠近基架组件20的一端，第一连杆71的第二端为第一连杆71在X轴方向上远离基架组件20的一端。
在一些实施例中，第二连杆72的第一端与第一转动组件40铰接，第二连杆72的第二端与支撑件31和第一连杆71的第一端铰接。第二连杆72通过两个铰接关系将第一转动组件40和支撑件31连接，使得铰链结构在折叠过程中在Y轴方向上强度更高。例如，如图1所示。其中，第二连杆72的第一端为第二连杆72在X轴方向上第一转动组件40远离基架组件20的一端，第二连杆72的第二端为第二连杆72在X轴方向上靠近基架组件20的一端。
其中，第一连杆71的第一端和第二连杆72的第二端并排铰接于第一转动组件40和第二转动组件50之间可以使得支撑组件30受力均匀，能够更稳定地绕基架组件20转动。在一些实施例中，第一连杆71和第二连杆72沿Y轴方向并排设置于第一转动组件40和第二转动组件50之间，使得第一连杆71和第二连杆72的转动方向能够垂直于Y轴方向，进而使支撑组件30处于折叠状态时可以更好地相互围合。
在一些实施例中，支撑组件30包括第一铰接部311。第一铰接部311具有不小于第一转动组件40的第一端、第一连杆71的第一端和第二连杆72的第二端的宽度之和的开口。 例如，如图1所示。如果开口小于第一转动组件40的第一端、第一连杆71的第一端和第二连杆72的第二端的宽度之和，则无法同时容纳第一转动组件40的第一端、第一连杆71的第一端和第二连杆72的第二端，使得支撑组件30、第一转动组件40的第一端、第一连杆71的第一端和第二连杆72的第二端无法铰接于同一铰接轴上。其中，铰接轴沿Y轴方向延伸。第一铰接部311可以使得连杆组件和第一转动组件40与支撑组件30铰接，使连杆组件和第一转动组件可以限制支撑组件30的转动轨迹。
在一些实施例中，第一转动组件40的第一端、第一连杆71的第一端、第二连杆的第二端设置于第一铰接部311的开口内，并且共同与支撑组件30的第一铰接部311铰接于同一铰接轴。其中，铰接轴沿Y轴方向延伸。
在一些实施例中，固定件32包括第一滑槽322，第二转动组件50的第二端可滑动地设置于固定件32的第一滑槽322内，例如，如图1所示，其中，第二转动组件50的第二端可以相对第一滑槽322滑动，第二转动组件50的第二端可以是第二转动组件50在X轴方向上远离基架组件20的一端。
第二转动组件50的第二端能够在固定件32的第一滑槽322内滑动，使得当支撑组件30的固定件32进行转动时，第二转动组件50保持与固定件32的连接的同时，还可以使得支撑组件30的转动轨迹避免受到第二转动组件50的长度的限制，从而使得支撑组件30顺利完成转动动作。
随着支撑组件30在展开状态或折叠状态间切换，第二转动组件50在第一滑槽322内滑动。
在一些实施例中，当支撑组件30处于展开状态时，第二转动组件50的第二端邻近于第一滑槽322的远离基架组件20的一端，当支撑组件30从展开状态切换至折叠状态时，第二转动组件50的第二端向第一滑槽322的靠近基架组件20的一端滑动。
在一些实施例中，固定件32还包括第二铰接部321，第二铰接部321与第一连杆71的第二端铰接。例如，如图1所示。其中，第一连杆71的第二端为第一连杆71在X轴方向上远离基架组件20的一端。
通过连杆组件、第一转动组件40、第二转动组件50和固定件32间的配合连接，共同带动支撑组件30进行转动，使得支撑组件30的运动精度更高，可以对容置于其间的部件起到保护作用。
当铰链结构用于电子设备时，使设置在第二支撑面33的屏幕折叠更为自然，有效保护屏幕。
在一些实施例中，支撑件31可以转动连接于固定件32。在支撑组件30的折叠过程中， 支撑件31和固定件32绕基架组件20转动的同时，支撑件31和固定件32基架之间也可以发生相对转动。
在一些实施例中，固定件32设置有第一弧形滑槽324，例如，如图2所示，第一弧形滑槽324在X轴方向和Z轴方向所构成的平面可以为弧形形状，并且第一弧形滑槽324可以在Y轴方向延伸，支撑件31可以设置有与第一弧形滑槽324对应的第一滑动部312，第一滑动部312可以为圆弧状突起结构，第一滑动部312可以在第一弧形滑槽324内滑动。但本公开不限于此，第一弧形滑槽324也可以不是弧形结构，是其他任意可以实施的形状。其中当第一弧形滑槽324为弧形结构时，可以减少第一滑动部312在第一弧形滑槽324中滑动的阻力，进而使支撑件31和固定件32间转动流畅。
在一些实施例中，第一弧形滑槽324一端为开口，例如可以称为滑槽开口。例如，如图3所示。滑槽开口可以设置于固定件32的Z轴方向的上表面，第一弧形滑槽324另一端为滑槽底部，滑槽底部为第一弧形滑槽324的弧形延伸的终点。滑槽底部的形状可以与第一滑动部312相匹配。滑槽底部可以设置于固定件32内部。
在一些实施例中，第一滑动部312为圆弧状突起结构，例如，如图3所示，但本公开不限于此，第一弧形滑槽324也可以不是弧形结构，是其他任意可以实施的形状。其中当第一滑动部312为圆弧状突起结构时，可以减少第一滑动部312在第一弧形滑槽324中滑动的阻力，进而使支撑件31和固定件32间转动流畅。其中第一滑动部312的在Z轴方向和X轴方向形成平面上的横截面形状为与第一弧形滑槽324的形状相匹配。
当支撑组件30处于展开状态时，第一滑动部312的至少一部分位于第一弧形滑槽324开口外侧，当支撑组件30从展开状态切换至折叠状态时，支撑件31和固定件32向折叠方向转动的同时，支撑件31和固定件32之间也发生相对转动，相对转动使得第一滑动部312向滑槽底部滑动，当支撑组件30处于折叠状态时，第一滑动部312抵靠于滑槽底部，通过第一滑动部312和第一弧形滑槽324的形状配合，可以限制支撑件31的转动轨迹，防止支撑件31在折叠或展开过程中浮起对容置于其中的部件造成损伤，在铰链结构用于电子设备时，可以防止支撑件31顶起屏幕，影响用户使用体验。
在一些实施例中，固定件32包括抵接斜面325，抵接斜面325位于固定件32的面向支撑件31的一面，第一弧形滑槽324的滑槽开口朝向抵接斜面一侧，以便于使第一弧形滑槽324和第一滑动部312配合运动。
当支撑组件30处于展开状态时，抵接斜面325与第一支撑面24和第二支撑面33呈倾斜设置，支撑件31与抵接斜面325间可以相互分离，当支撑组件30处于折叠状态时，支撑件31可以与抵接斜面325抵接。抵接斜面325在转动过程中从支撑件31的背离第二 支撑面33的一面对支撑件31的转动角度进行了限定，使得支撑件31的转动角度更为精准。
在一些实施例中，铰链结构还可以包括限位件80。限位件80可以用于对支撑件31起到限位的作用，具体可以防止支撑件31在展开状态下浮起，进而可以提供铰链结构的稳定的支撑面。
在一些实施例中，支撑件31可以包括第一安装部313，第一安装部313可以设置于支撑件31的背离第二支撑面33的一面，并可以设置在支撑件31靠近基架组件20的一侧，第一安装部313设置有一个或两个铰接孔，也可以设置有更多铰接孔。
在一些实施例中，限位件80的一端设置有第三铰接部82，通过第三铰接部82和第一安装部313的铰接，限位件80完成与支撑件31铰接。
通过第三铰接部82和第一安装部313间的铰接关系，使得限位件80可以与支撑组件30定点相连的同时可以绕第一安装部313转动，使得限位件80在限定支撑组件30的运动轨迹的同时，留有支撑组件30正常转动的空间。
在一些实施例中，限位件80的另一端设置有固定部81，固定件32的垂直于折叠方向的表面上设置有第二滑槽323。
在一些实施例中，固定部81可以是垂直于限位件80长度方向的突出结构。
在一些实施例中，限位件80的固定部81可滑动地设置于第二滑槽323，限位件80的固定部81可以相对第二滑槽323滑动。
在一些实施例中，第二滑槽323的延伸方向可以平行于第二转动组件50在支撑组件30的滑动方向，例如，如图1所示，即第二滑槽323的延伸方向可以平行于X轴方向，这使得限位件80的固定部81在第二滑槽323滑动时，限位件80收到的拉力的角度与第二滑槽323的延伸方向相近，使得支撑组件30在转动过程中更为流畅。
当支撑组件30从折叠状态切换至展开状态时，支撑件31可以拉动固定部81向第二滑槽323的靠近基架组件20一侧的第一端滑动，当支撑组件30处于展开状态时，固定部81抵靠于第二滑槽323的靠近基架组件20一侧的第一端。此时限位件80在第二滑槽323的第一端方向上固定，进而使限位件80可以对支撑件31的运动进行限制，防止支撑件31在展开状态中浮起，对容置于其中的部件造成损伤，在铰链结构用于电子设备时，顶起屏幕，影响用户使用体验。
通过第一滑动部312对支撑件31的限制作用和限位件80对支撑件31的限制作用，使得支撑组件30处于展开状态时，不会有部分支撑组件30浮起，避免影响柔性屏幕展开后的平整性，提升了显示屏的使用体验。
在一些实施例中，基架组件20还包括基架21和盖板22。盖板设置于基架组件20的与第一支撑面24背离的一面，盖板22可以对设置于基架组件20的部件起到固定作用。盖板22还可以起到保护基架组件20的作用，防止异物进入基架组件20内部造成基架组件20内的部件的损坏。
第一支撑面24设置于基架21的第一面，基架21还包括背离第一支撑面24的第二面。
基架21的第二面设置有第二安装部212，第二转动组件50的第一端设置于基架21的第二面，并且第二转动组件50与基架21的第二安装部212铰接，第二安装部212为第二转动组件50提供了转动支点。
在一些实施例中，第二安装部212可以是设置于基架21的第二面的一个或多个突起结构，突起结构可以设置有多个通孔，第二转动组件50的第一端为柱体结构，第二转动组件50的第一端的柱体结构可以与第二安装部212的通孔配合达成铰接。
在一个实施例中,如图1所示，第二安装部212用于固定第二转动件51，第二安装部212包括：本体以及设置与本体上的通孔，通孔可以为圆形或方形等形状通孔，第二转动组件50的第一端为圆柱体结构，并且第二转动组件50的圆柱体结构的长度方向与第二转动组件50的长度方向垂直，即第二转动组件50的圆柱体结构的长度方向与Y轴方向平行。
在一些实施例中，第二安装部212的通孔的开孔方向平行于第一支撑面24，并且还平行于基架21的长度方向，即与Y轴方向平行。
在一些实施例中，基架21在靠近第二安装部212的位置设置有避让部213，避让部213可以是缺口结构，避让部213可以使得第二转动组件50的转动不受基架21妨碍。
在一些实施例中，盖板22安装于基架21的第二面。基架21的第二面为背离第一支撑面24的一面。
在一些实施例中，盖板22和基架21中的一者设置有弧形凸起211，盖板22和基架21中的另一者设置有弧形凹槽221，弧形凸起211和弧形凹槽221弧度相匹配，使得弧形凸起211和弧形凹槽221合围成第二弧形滑槽。其中，第二弧形滑槽设置于基架21的第二面。
在一些实施例中，第一转动组件40的第二端设置有与第二弧形滑槽匹配的弧形结构，第一转动组件40的第二端设置于第二弧形滑槽内，使得第一转动组件40可转动地设置于基架组件20，使得第一转动组件40与支撑组件30保持连接的同时，还可以使得支撑组件30的转动轨迹免收第一转动组件40的长度的限制，从而使得支撑组件30顺利完成动作
在一些实施例中，当支撑组件30处于展开状态时，第一转动组件40的第二端抵靠于基架21，这可以限制支撑组件30处于展开状态时过度旋转，避免拉伸柔性的显示屏幕， 对柔性的显示屏幕具有保护作用。
在一些实施例中，第一转动组件40的转动中心线与第二转动组件50的转动中心线平行。
在一些实施例中，如图1所示，第一转动组件40的转动中心线与第二转动组件50的转动中心线分别与基架组件20的转动中心线平行且不同轴，即与Y轴方向平行，这使得支撑组件30的转动能够垂直于Y轴方向，使得支撑组件30的折叠状态和展开状态外观平齐。

在一些实施例中，支撑件31、第一转动组件40、第一连杆71和第二连杆72间同轴铰接。这使得支撑件31、第一转动组件40、第一连杆71和第二连杆72可以绕同一旋转轴旋转，提升了支撑板的运动精度。
在一些实施例中，铰链结构还包括同步组件60，同步组件60用于同步带动连接于基架组件20两侧的第二转动组件50展开或折叠。
在一些实施例中，同步组件60可以是与第二安装部212的通孔配合的杆状结构，使得同步组件60可以在第二安装部212的通孔内转动。
在一些实施例中，同步组件60和第二转动组件50的第一端(即靠近基架组件的一端)设置有相互啮合的轮齿结构，并且轮齿数和齿轮直径相同，齿轮数为偶数个，这使得第二 转动组件50的第一转动件51或第二转动件52中的一者转动时，能够通过同步组件60将转动同步至第二转动组件50的第一转动件51或第二转动件52中的另一者。进而使得第二转动组件50能够带动支撑组件30进行同步的展开动作或折叠动作。
在一些实施例中，第二转动组件50包括第一转动件51和第二转动件52，第一转动件51和第二转动件52可以分别连接于基架组件20的相对两侧。在这种情况下，同步组件60与第一转动件51的第一端和第二转动件52的第一端之间均可以设置有相互啮合的轮齿结构，并且轮齿数和齿轮直径相同，齿轮数为偶数个，这使得第一转动件51或第二转动件52中的一者转动时，能够通过同步组件60将转动同步至第二转动组件50的第一转动件51或第二转动件52中的另一者。进而使得第二转动组件50能够带动支撑组件30进行同步的展开动作或折叠动作。
在一些实施例中，当支撑组件30从展开状态切换至折叠状态时，支撑组件30向折叠方向运动，第一转动组件40、第二转动组件50和连杆组件也向折叠角度进行运动，第二转动组件50的滑动部501向第一滑槽322的靠近基架组件20的一端移动，限位件80向第二滑槽323的靠近基架组件20一侧的第一端滑动。同时，第一滑动部312随着支撑组件30从展开角度向折叠角度运动，而向第一弧形滑槽324的滑槽底部方向滑动。需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。

在一些实施例中，固定件32的背离抵接斜面325的一面上设置有在柔性屏幕折叠后用于显示功能的第二块屏幕，铰链结构处于折叠角度时，固定件32的背离抵接斜面325的一面应当互相平行且垂直于第一支撑面24，使得手机处于折叠状态时外观面保持平齐美观。
在一些实施例中，当支撑组件30处于展开角度时，柔性屏幕处于展开状态，柔性屏幕可以正常进行工作，当支撑组件30处于折叠角度时，柔性屏幕处于折叠状态，柔性屏幕可以熄灭进入待机状态。
在一些实施例中，当支撑组件30处于折叠角度时，柔性屏幕的横截面形状为水滴形，水滴形的折叠界面形状一方面在折叠拐角处更加符合柔性屏幕的自然折叠状态，可以减轻柔性屏幕产生折痕，有效地保护了柔性屏幕，另一方面其余部分的机体空隙大大缩小，两部分机体间可以贴合，减少了折叠状态下的机身厚度，符合目前电子设备轻薄化的发展趋势，提升了用户体验。
