在介绍本申请的技术方案之前，再详细介绍下相关技术中的技术问题。
随着显示技术的不断发展，用户对电子设备的要求越来越高，因而研发并推出了多种多样的电子设备，例如折叠式电子设备、滑卷式电子设备、卷轴式电子设备等等。其中折叠式电子设备因其独有的折叠性能，在展开状态时具有较大的显示面积，在折叠状态时具有较小的整机尺寸，现已受到越来越多的用户的喜爱。折叠式的电子设备从弯折方向上来说可以分为内折与外折。其中，内折指的是两半的柔性屏较壳体相互靠近并被壳体给保护起来，使得在折叠状态时用户看不到柔性屏。外折指的是两半柔性屏相较壳体相互远离，虽然柔性屏无法得到壳体的保护，但在折叠状态下依然可以使用户观看到其显示画面。并且对于内折来说，根据柔性屏折叠后的截面形状可分为U形与水滴形。其中，U形顾名思义指的是柔性屏弯折后其截面形状酷似字母U进而得到的命名。水滴形顾名思义指的是柔性屏弯折后其截面形状酷似水滴形状而得到的命名。换句话说，水滴形的柔性屏其两半屏幕之间的间距具有上小下大的特点。
无论是内折还是外折，无论是形成U形还是水滴形，目前为了实现折叠式电子设备的折叠功能通常采用装设于电子设备内的折叠装置。折叠装置依靠其支撑件相对支架运动，并通过其他结构件的配合以按照预设好的运动轨迹进行运动，从而在折叠状态时可将屏幕限制成U形或水滴形。但目前的折叠装置结构复杂、整体宽度较大，占用的空间较多，不利于小型化发展。例如有些折叠装置中的连接件可相对转动件进行滑动，这就会使得折叠装置、以及应用该折叠装置的壳体组件与电子设备在其长度方向上的尺寸会发生变化，因此导致折叠装置的结构较复杂，整体长度会变大且会占用较多的空间，从而减小其他结构件例如主板或电池等的装设空间。并且滑槽式结构在折叠装置遇到突发情况时(例如跌落)，无法支撑连接件，影响折叠装置的可靠性。
基于此，为了解决上述问题，本申请提供了一种折叠装置。请一并参考图1-图8，图1为本申请一实施方式中折叠装置处于展开状态时的立体结构示意图。图2为图1所示的折叠装置另一视角的立体结构示意图。图3为图1的折叠装置的爆炸图。图4为图1所示的折叠装置的正视图。图5为本申请一实施方式中支架的立体结构示意图。图6为本申请一实施方式中折叠装置处于折叠状态时的立体结构示意图。图7为图6所示的折叠装置另一视角的立体结构示意图。图8为图6所示的折叠装置的正视图。

折叠装置1主要包括支架10、两个转动机构、支撑机构30、以及从动机构70，本实施方式仅利用支架10、两个转动机构、支撑机构30、以及从动机构70便可解决上述提及的技术问题，但这并不意味着折叠装置1只能具有上述这机构，折叠装置1还可以具有其他机构例如同步机构、悬停机构等等。接下来本实施方式将依次对支架10、两个转动机构、支撑机构30、以及从动机构70及进行详细地介绍。
支架10是折叠装置1中的基础结构件，主要起到支撑、装设的作用，可以使折叠装置1中的其他结构件例如转动件与从动件71等部件装设在支架10上。并且支架10在部分实施方式中还能够起到支撑屏幕的作用。其中屏幕包括但不限于各种屏幕，或者各种刚性件，或者其他部件。本实施方式并不对支架10的形状、结构、材质等参数进行限制，只要能为其他结构件提供装配基础即可。
可选地，支架10具有相背设置的顶面101与底面102、及弯折连接于顶面101与底面102之间的两个第一侧面103、及两个第二侧面104，两个第一侧面103间隔设置，两个第二侧面104间隔设置，且两个第二侧面104弯折连接于两个第一侧面103的相对两侧。第一侧面103靠近后续的转动机构20且第一侧面103的形状为弧形以使顶面101的宽度大于底面102的宽度。由于顶面101后续需要装设各种结构件，而底面102通常不需要装配部件或装配的部件较少，因此使顶面101大，底面102小可减小支架10的尺寸，装设更多的结构件。另外，第一侧面103设计成弧形可在运动的过程中避让转动机构20或壳体等其他结构件，防止在运动的过程中出现干涉的问题。至于第二侧面104可以设计成平面以便后续在第二侧面104上装设其他结构件，例如从动机构70、同步机构、悬停机构等等。
转动机构是折叠装置1中的核心机构之一，主要实现折叠装置1的转动功能，并通过转动机构的转动从而驱动与限定和转动机构所连接的部件，使这些部件按照预设的运动轨迹进行运动。第一转动机构20主要包括第一转动件21、第二转动件22、及连接件23。其中第一转动件21与第二转动件22主要起转动的作用，连接件23主要起中间连接的作用，连接件23后续用于固设于壳体上。第一转动件21的一端转动连接于支架10上，即第一转动件21靠近支架10的一端转动连接于支架10上。换句话说，支架10通常是固定不动的，因此第一转动件21可相对支架10进行转动。并且，第二转动件22的一端同样转动连接于支架10上，即第二转动件22靠近支架10的一端转动连接于支架10上。换句话说，支架10通常是固定不动的，因此第二转动件22可相对支架10进行转动。至于第一转动件21与第二转动件22的和支架10的具体配合结构本申请在后文再进行详细介绍。
第一转动件21的另一端转动连接于连接件23，即第一转动件21远离支架10的一端转动连接于连接件23。换句话说，第一转动件21可相对连接件23进行转动。并且第二转动件22的另一端同样转动连接于连接件23，即第二转动件22远离支架10的一端转动连接于连接件23。换句话说，第二转动件22可相对连接件23进行转动。至于第一转动件21与第二转动件22和支架10的具体配合结构本申请在后文再进行详细介绍。两个转动件与连接件23为转动连接，可使得连接件23只会相对两个转动件进行转动不会进行滑动，可避免连接件23相对两个转动件进行滑动从而增加折叠装置1的尺寸，实现了折 叠装置1小型化的目的。并且两个转动件转动连接连接件23，可使得当折叠装置1遇到突发情况时(例如跌落)，有效利用转动结构支撑连接件23，提高了折叠装置1的可靠性。
连接件23可固设于壳体上，从而实现当壳体转动时带动连接件23转动。在一些实施方式中连接件23与壳体可以为一体式结构或分体式结构。当连接件23与壳体为一体式结构时，连接件23与壳体是通过一道工序制备而成，只不过为了便于理解，人为将连接件23与壳体进行了不同的命名。当连接件23与壳体为分体式结构时，连接件23与壳体是分开制备的，然后再通过各种方法例如粘接、螺钉连接、卡扣连接等方法将连接件23固设于壳体上。本实施方式仅以连接件23与壳体为分体式结构进行示意性说明。
本实施方式并不对第一转动件21、第二转动件22、及连接件23的形状、结构、材质等参数进行限定，只要第一转动件21与第二转动件22的一端能与支架10转动连接、第一转动件21与第二转动件22的另一端能与连接件23转动连接即可。
另外，第一转动件21与连接件23转动连接时，第一转动件21与连接件23之间具有第一转动轴心线C1(如图4中C1所示)。第二转动件22与连接件23转动连接时，第二转动件22与连接件23之间具有第二转动轴心线C2(如图4中C2所示)。本实施方式可使第一转动轴心线C1与第二转动轴心线C2相互平行。其中“相互平行”指的是第一转动轴心线C1的延伸方向与第二转动轴心线C2的延伸方向相同，并且第一转动轴心线C1与第二转动轴心线C2之间具有一定间距，即第一转动轴心线C1与第二转动轴心线C2是相互平行且不重合的。上述设计可使得当折叠装置1处于静止状态时即折叠装置1未转动时连接件23被限制不能相对第一转动件21与第二转动件22进行转动，其与第一转动件21与第二转动件22保持相对静止，提高了折叠装置1结构的稳定性。但当折叠装置1处于运动过程中时，连接件23的转动仍可带动第一转动件21与第二转动件22进行转动，并且第一转动件21与和/或第二转动件22可相对支架10与连接件23进行转动。
第二转动机构20'与第一转动机构20相同，也包括第一转动件21、第二转动件22、及连接件23；所述第一转动件21与所述第二转动件22的一端均转动连接于所述支架10，所述第一转动件21与所述第二转动件22的另一端均转动连接于所述连接件23，且所述第一转动件21与所述连接件23之间的第一转动轴心线C1平行不重合于所述第二转动件22与所述连接件23之间的第二转动轴心线C2。第二转动机构20'中的第一转动件21、第二转动件22、及连接件23可参考第一转动机构20中的第一转动件21、第二转动件22、及连接件23，本实施方式在此不再赘述。
支撑机构30在折叠装置1中主要用于后续支撑屏幕，并且支撑机构30作为折叠装置1中受约束的机构，它可以受到其它机构的运动轨迹的限制从而进行运动，最终实现所需的折叠形态，进而带动屏幕弯折形成所需的形状。本实施方式中支撑机构30包括第一支撑件31与第二支撑件31'，第一支撑件31与第二支撑件31'用于支撑屏幕，第一支撑件31具有用于支撑屏幕的支撑面310。可选地，屏幕可抵接支撑面310，或者屏幕可与支撑面310之间具有间隙。第一支撑件31转动连接于连接件23，即第一支撑件31可相对于连接件23进行转动。第一支撑件31还可与后续的从动机构70相互配合。第二支撑件31'具有用于支撑屏幕的支撑面310。可选地，屏幕可抵接支撑面310，或者屏幕可与支撑面310之间具有间隙。第二支撑件31'转动连接于连接件23，即第二支撑件31'可相对于连接件23进行转动。第二支撑件31'还可与后续的从动机构70相互配合。
这里需要注意的是，上述提及的转动可以理解为两个运动件可绕着转动轴心线进行圆周运动。本实施方式并不对第一支撑件31与第二支撑件31'的形状、结构、材质等参数进行限定，只要第一支撑件31与第二支撑件31'能起到支撑屏幕、且转动连接连接件23与从动件71的作用即可。
从动机构70在折叠装置1中起辅助运动的作用，主要用于控制并驱动第一支撑件31与第二支撑件31'进行运动，使第一支撑件31与第二支撑件31'按照特定的轨迹进行运动。从动机构70包括至少部分设于支架10相对两侧的第一从动件71与第二从动件71'。第一从动件71的一端转动连接于支架10上，即第一从动件71靠近支架10的一端可相对支架10进行转动。至于第一从动件71的另一端则转动连接 于第一支撑件31上，即第一从动件71远离支架10的一端可相对第一支撑件31进行转动，换句话说，第一支撑件31也可相对第一从动件71进行转动。
第二从动件71'的一端转动连接于支架10上，即第二从动件71'靠近支架10的一端可相对支架10进行转动。至于第二从动件71'的另一端则转动连接于第二支撑件31'上，即第二从动件71'远离支架10的一端可相对第二支撑件31'进行转动，换句话说，第二支撑件31'也可相对第二从动件71'进行转动。本实施方式并不对第一从动件71与第二从动件71'的形状、结构、材质等参数进行限定，只要第一从动件71与第二从动件71'能实现上述的连接关系，起到辅助运动的作用即可。
本实施方式提供的折叠装置1包括一个支撑机构30、一个从动机构70、以及两个转动机构。一个支撑机构30、一个从动机构70、以及两个转动机构构成一个整体机构，该整体机构设于支撑机构30中的第一支撑件31与第二支撑件31'背离支撑面310的一侧。在其他实施方式中，折叠装置1包括两个支撑机构30、两个从动机构70、以及四个转动机构，每一个支撑机构30与一个从动机构70、两个转动机构构成一个整体机构，两个整体机构均设于支撑机构30中的第一支撑件31与第二支撑件31'背离支撑面310的一侧，且沿第一支撑件31的长度方向间隔设置。当然在其他实施方式中折叠装置1也可包括三个或以上的支撑机构30，三个或以上的从动机构70、六个或以上的转动机构，每一个支撑机构30与一个从动机构70和两个转动机构构成一个整体机构，三个或以上的整体机构均设于支撑机构30中的第一支撑件31与第二支撑件31'背离支撑面310的一侧，且沿第一支撑件31与第二支撑件31'的长度方向间隔设置。
基于上述的连接关系，使得折叠装置1不仅可进行折叠还可按照预设的折叠轨迹进行运动，得到所需的折叠形态。具体地：当所述折叠装置1折叠时，所述第一从动件71、所述第二从动件71'、及所述第一转动机构20与所述第二转动机构20'的所述第一转动件21、所述第二转动件22转动，所述第一支撑件31及所述第二支撑件31'相互折叠；当所述折叠装置1展开时，所述第一从动件71、所述第二从动件71'、及所述第一转动机构20与所述第二转动机构20'的所述第一转动件21、所述第二转动件22转动，所述第一支撑件31及所述第二支撑件31'相互展开。
上述提及的折叠装置1的运动过程具有多种主动、从动逻辑关系，本申请以其中的一种具体的运动过程进行举例说明。当折叠装置1折叠或展开时，即当连接件23相对支架10转动时由于第一转动件21与第二转动件22转动连接支架10，因此连接件23可带动第一转动件21与第二转动件22相对支架10进行转动。同时由于第一支撑件31转动连接于连接件23上，因此当连接件23相对支架10转动时可使第一支撑件31同步相对支架10转动。并且由于第一从动件71的两端分别转动连接于支架10与第一支撑件31，因此第一支撑件31相对支架10转动时可带动第一从动件71也相对支架10转动，最终使第一支撑件31与第二支撑件31'相互折叠或相互展开。当然在其他实施方式中上述多个结构件的主动被动关系可以颠倒，例如也可以为第一转动件21与第二转动件22相对支架10转动从而带动连接件23相对支架10进行转动。此类运动过程与原理也应属于本申请的保护范围。
当第一支撑件31与第二支撑件31'相互平行，且第一支撑件31与第二支撑件31'位于支架10的相对两侧时，也可以理解为第一支撑件31靠近支架10的第一侧面103时，此时第一支撑件31与第二支撑件31'处于完全相互展开的状态，换句话说折叠装置1处于展开状态，如图4所示。当第一支撑件31与第二支撑件31'相互平行，且第一支撑件31与第二支撑件31'均位于支架10的一侧时，也可以理解为第一支撑件31与第二支撑件31'均位于支架10的顶面101时，此时第一支撑件31与第二支撑件31'处于完全相互折叠的状态，换句话说折叠装置1处于折叠状态，如图8所示。当第一支撑件31与第二支撑件31'相互折叠时，即折叠装置1从展开状态至折叠状态的过程，也可以理解为从图4至图8的过程，此时两个连接件23相互转动并相互靠近带动第一支撑件31与第二支撑件31'相互合并，以实现相互靠近与折叠。当第一支撑件31与第二支撑件31'相互展开时，即折叠装置1从折叠状态至展开状态的过程，也可以理解为从图8至图4的过程，此时两个连接件23相互转动并相互远离带动第一支撑件31与第二支撑件31'相互分开，以实现相互远离与展开。
当折叠装置1处于折叠状态时，第一支撑件31与第二支撑件31'与支架10可共同围设形成用于收容屏幕的收容空间11，本实施方式提供的折叠装置1可使屏幕的横截面形状为U形或水滴形。本实施方式仅以收容空间11的截面形状为水滴形进行示意性说明。
综上，本实施方式提供的折叠装置1，通过采用支架10、转动机构、支撑机构30、及从动机构70的相互配合便可实现第一支撑件31与第二支撑件31'的相互折叠与相互展开，即实现折叠装置1的折叠与展开功能。并且第一转动件21与第二转动件22分别在与连接件23之间的第一转动轴心线C1与第二转动轴心线C2平行且不重合，可在实现第一支撑件31正常运动的基础上使得折叠装置1的长度较小且在长度方向上的尺寸不会发生变化，使得折叠装置1的结构紧凑，从而减小折叠装置1占用壳体组件与电子设备的内部空间，不仅有利于主板或电池等其他结构件的布局。相较于相关技术中连接件23可相对转动件滑动的方案还有利于折叠装置1小型化的发展。其中，上述提及的折叠装置1长度方向可以理解为折叠装置1处于展开状态时第一支撑件31与第二支撑件31'与支架10的排列方向。
另外，第一转动轴心线C1与第二转动轴心线C2平行且不重合可使得连接件23不会相对第一转动件21与第二转动件22进行转动，提高了折叠装置1的稳定性。
可选地，当折叠装置1处于展开状态时，第一支撑件31与第二支撑件31'的支撑面310可与支架10的顶面101共面，使得屏幕可抵接于第一支撑件31与第二支撑件31'的支撑面310与支架10的顶面101上。当然在其他实施方式中支撑机构30还可包括设于第一支撑件31与第二支撑件31'之间的承载件(图中未示出)，承载件装设于支架10的顶面101上，承载件也同样具有用于支撑屏幕的承载面。当折叠装置1处于展开状态时，第一支撑件31的支撑面310与承载件的承载面共面，使得屏幕可抵接于第一支撑件31的支撑面310与承载件的承载面上。
并且，本申请的各种实施方式的说明是参考附加的图示，用以例示本申请可用以实施的特定实施方式。本申请中所提到的方向用语，例如，“上”、“下”、“前”、“后”、“左”、“右”、“内”、“外”、“侧面”等，仅是参考附加图式的方向，因此，使用的方向用语是为了更好、更清楚地说明及理解本申请，而不是指示或暗指所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“设置在上”应做广义理解，例如，可以是固定连接，也可以是可拆卸地连接，或者一体地连接，可以是机械连接，可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。例如本实施方式中的各种连接是包括直接连接和间接连接两种情况，比如两个结构件连接包括两个结构件直接连接或者通过第三个结构件或更多的其他结构件进行连接。连接还包括一体化连接和非一体化连接两种情况，一体化连接是指两个部件是一体形成并连接，非一体化连接是指A和B是非一体化形成并连接。
请再次参考图8，本实施方式中，第一支撑件31还相对第一转动机构20的连接件23转动，第二支撑件31'还相对第二转动机构20'的连接件23转动，以使第一支撑件31与第二支撑件31'处于完全相互折叠状态时第一支撑件31与第二支撑件31'均位于支架10的同一侧，且第一支撑件31与第二支撑件31'在远离支架10一端之间的距离小于或等于第一支撑件31与第二支撑件31'在靠近支架10一端之间的距离。
当折叠装置1在运动时，第一支撑件31与第二支撑件31'除了可相对第一从动件71与第二从动件71'进行转动之外，第一支撑件31与第二支撑件31'还可相对第一转动机构20的连接件23进行转动，具体地，可使第一支撑件31靠近支架10的一端朝向靠近连接件23的一端转动，从而使折叠装置1处于折叠状态时第一支撑件31与第二支撑件31'在远离支架10一端之间的距离小于第一支撑件31与第二支撑件31'在靠近支架10一端之间的距离，即第一支撑件31与第二支撑件31'之间形成上小下大的间隙。换句话说，第一支撑件31与第二支撑件31'与支架10围设形成的收容空间11为上小下大的形状，即水滴形的收容空间11，进而使屏幕的截面形状为水滴形。至于具体如何设计折叠装置1的结构从而限制第 一支撑件31的运动轨迹最终实现收容空间11的截面形状为水滴形，本申请将在下文进行详细介绍。
在其他实施方式中，第一从动件71与第二从动件71'的另一端也可不驱动第一支撑件31与第二支撑件31'相对连接件23转动，此时折叠装置1处于折叠状态时第一支撑件31与第二支撑件31'与支架10便可围设形成U形的收容空间11。换句话说，第一支撑件31与第二支撑件31'处于完全相互折叠状态时第一支撑件31与第二支撑件31'均位于支架10的同一侧，且第一支撑件31与第二支撑件31'在远离支架10一端之间的距离等于第一支撑件31与第二支撑件31'在靠近支架10一端之间的距离，即第一支撑件31与第二支撑件31'之间形成上下等宽的间隙。
接下来，本申请将着重介绍第一转动机构20、第一支撑件31、以及第一从动件之间的具体结构以及位置关系。请再次参考图4与图8，本实施方式中，折叠装置1具有第一支撑件31与第二支撑件31'处于完全相互展开时的展开状态，及第一支撑件31与第二支撑件31'处于完全相互折叠时的折叠状态，支架10具有用于靠近屏幕的顶面101。其中，当折叠装置1处于展开状态时在平行于顶面101的方向上，第一支撑件31与第一从动件71之间的第三转动轴心线C3、及第一支撑件31与第一转动机构20的连接件23之间的第四转动轴心线C4之间的距离为第一距离。当折叠装置1处于折叠状态时在垂直于顶面101的方向上，第三转动轴心线C3及第四转动轴心线C4之间的距离为第二距离，第二距离小于第一距离。
关于折叠装置1的展开状态与折叠状态本申请在上文已经进行了详细介绍，本实施方式在此不再赘述。由于第一支撑件31与第一从动件71远离支架10的一端转动连接，因此第一支撑件31与第一从动件71之间具有第三转动轴心线C3。同理第一支撑件31与第一转动机构20的连接件23也为转动连接，因此第一支撑件31与第一转动机构20的连接件23之间具有第四转动轴心线C4。当折叠装置1从展开状态至折叠状态的过程中，可使第三转动轴心线C3与第四转动轴心线C4之间的距离产生变化，从而驱动第一支撑件31相对第一转动机构20的连接件23进行转动。具体地，在本实施方式中，可使第三转动轴心线C3与第四转动轴心线C4在平行于顶面101的方向上，即图4中的水平方向上两者的间距逐渐减小。请参考图4与图8，当折叠装置1处于展开状态时，第三转动轴心线C3与第四转动轴心线C4在平行于顶面101方向上的距离为第一距离即L1，当折叠装置1处于折叠状态时，第三转动轴心线C3与第四转动轴心线C4在垂直于顶面101方向上的距离为第二距离即L1'且L1'小于L1。当两个轴心线之间的距离减小时便会带动第一支撑件31发生倾斜，不再平行于屏幕。而是向靠近第一转动机构20的连接件23的方向转动，因此第一支撑件31便可相对第一转动机构20的连接件23转动从而形成上述形态。
同理，当折叠装置1从折叠状态至展开状态的过程中，第三转动轴心线C3与第四转动轴心线C4在平行于顶面101的方向上的间距逐渐增加，使得倾斜于屏幕的第一支撑件31可相对第一转动机构20的连接件23朝向远离第一转动机构20的连接件23的方向反向转动，使屏幕逐渐平行于屏幕。
可选地，第三转动轴心线C3与第四转动轴心线C4距离的变化可以理解为第三转动轴心线C3固定不动，第四转动轴心线C4靠近第三转动轴心线C3运动。或者第四转动轴心线C4固定不动，第三转动轴心线C3靠近第四转动轴心线C4运动。或者第三转动轴心线C3与第四转动轴心线C4相对运动。本实施方式仅以第四转动轴心线C4固定不动，第三转动轴心线C3靠近第四转动轴心线C4运动进行示意性说明。
至于第三转动轴心线C3与第四转动轴心线C4和第一转动轴心线C1与第二转动轴心线C2之间的位置关系，本申请在此并不进行限定。
请再次参考图4与图8，本实施方式中，折叠装置1具有第一支撑件31与第二支撑件31'处于完全相互展开时的展开状态，及第一支撑件31与第二支撑件31'处于完全相互折叠时的折叠状态，支架10具有用于靠近屏幕的顶面101。其中，当折叠装置1处于展开状态时在垂直于顶面101的方向上，第一支撑件31与第一从动件71之间的第三转动轴心线C3、及第一支撑件31与第一转动机构20的连接件23之间的第四转动轴心线C4之间的距离为第三距离。当折叠装置1处于折叠状态时在平行于顶面101 的方向上，第三转动轴心线C3及第四转动轴心线C4之间的距离为第四距离，第四距离大于第三距离。
本实施方式也可在垂直于顶面101的方向上使第三转动轴心线C3与第四转动轴心线C4之间的距离产生变化，从而驱动第一支撑件31相对第一转动机构20的连接件23进行转动。具体地，可使第三转动轴心线C3与第四转动轴心线C4在垂直于顶面101的方向上，即图4中的竖直方向上两者的间距逐渐增加。请参考图4与图8，当折叠装置1处于展开状态时，第三转动轴心线C3与第四转动轴心线C4在垂直于顶面101方向上的距离为第三距离即L2，当折叠装置1处于折叠状态时，第三转动轴心线C3与第四转动轴心线C4在平行于顶面101方向上的距离为第四距离即L2'且L2'大于L2。当两个轴心线之间的距离增加时便会带动第一支撑件31发生倾斜，不再平行于屏幕。而是向靠近第一转动机构20的连接件23的方向转动，因此第一支撑件31便可相对第一转动机构20的连接件23转动从而形成上述形态。
同理，当折叠装置1从折叠状态至展开状态的过程中，第三转动轴心线C3与第四转动轴心线C4在垂直于顶面101的方向上的间距逐渐减小，使得倾斜于屏幕的第一支撑件31可相对第一转动机构20的连接件23朝向远离第一转动机构20的连接件23的方向反向转动，使屏幕逐渐平行于屏幕。
可选地，第三转动轴心线C3与第四转动轴心线C4在垂直于顶面101的方向上距离的变化可以理解为第三转动轴心线C3固定不动，第四转动轴心线C4远离第三转动轴心线C3运动。或者第四转动轴心线C4固定不动，第三转动轴心线C3远离第四转动轴心线C4运动。或者第三转动轴心线C3与第四转动轴心线C4相向运动。本实施方式仅以第四转动轴心线C4固定不动，第三转动轴心线C3远离第四转动轴心线C4运动进行示意性说明。
另外，在一些实施方式中上述两种实施方式可同时存在，即在平行于顶面101的方向上，以及垂直于顶面101的方向上，第三转动轴心线C3与第四转动轴心线C4的运动可同时满足。
请一并参考图9-图10，图9为本申请一实施方式中第一支撑件与第一转动机构的连接件的配合示意图。图10为图9所示的第一支撑件与第一转动机构的连接件的分解示意图。本实施方式中，第一支撑件31包括支撑部313与导向部315，支撑部313具有用于支撑屏幕的支撑面310，导向部315固设于与支撑面310相背离的一侧表面，导向部315与第一转动机构20的连接件23之间通过第一圆弧轨3151与第一圆弧槽3150配合连接，第一圆弧轨3151设于导向部315与第一转动机构20的连接件23中的一者，第一圆弧槽3150设于导向部315与第一转动机构20的连接件23中的另一者。
第一支撑件31中的支撑部313用于支撑屏幕，因此支撑部313具有用于支撑屏幕的支撑面310。导向部315设于支撑部313的一侧，且导向部315用于与第一转动机构20的连接件23实现转动连接。具体地，本实施方式中支撑部313为矩形板状，支撑部313除了具有支撑面310及与支撑面310相背的非支撑面311外，支撑部313还具有设于支撑面310与非支撑面311之间的周侧面312，导向部315设于非支撑面311上即导向部315相较于支撑部313靠近第一转动机构20的连接件23。
另外，支撑部313与导向部315可以为一体式结构，也可以为分体式结构。当支撑部313与导向部315为一体式结构时，支撑部313与导向部315是通过一道工序制备而成，只不过为了便于理解，人为将支撑部313与导向部315进行了不同的命名。当支撑部313与导向部315为分体式结构时，支撑部313与导向部315是分开制备的，然后再通过各种方法连接在一起。本实施方式仅以支撑部313与导向部315为一体式结构进行示意性说明。
因此上述提及的第一支撑件31与第一转动机构20的连接件23转动连接即为导向部315与第一转动机构20的连接件23转动连接。具体地，导向部315与第一转动机构20的连接件23之间通过第一圆弧槽3150与第一圆弧轨3151配合连接。第一圆弧槽3150设于导向部315与第一转动机构20的连接件23中的一者，第一圆弧轨3151设于导向部315与第一转动机构20的连接件23中的另一者。例如当第一圆弧槽3150设于导向部315时第一圆弧轨3151设于第一转动机构20的连接件23上，当第一圆弧槽3150设于第一转动机构20的连接件23上时第一圆弧轨3151设于导向部315上。本实施方式仅以第一圆弧槽3150设于导向部315、第一圆弧轨3151设于第一转动机构20的连接件23上进行示意性说明。 具体地，导向部315靠近第一转动机构20的连接件23的一侧表面设有圆弧形的槽体，第一转动机构20的连接件23相对应地设置有插设于第一圆弧槽3150的圆弧形的块体，第一圆弧轨3151可设于第一圆弧槽3150内并抵接第一圆弧槽3150的内壁，且第一圆弧槽3150的轴心线与第一圆弧轨3151的轴心线共线，第一圆弧槽3150的轴心线与支撑部313和第一转动机构20的连接件23之间的转动轴心线共线，使得支撑部313可相对第一转动机构20的连接件23进行转动。至于第一圆弧槽3150与第一圆弧轨3151的尺寸与弧度可根据所需的第四转动轴心线C4的位置进行设计。另外，采用圆弧槽与圆弧柜的设计方式可使得第四转动轴心线C4的位置既可在导向部315内可也位于导向部315外，例如可根据改变圆弧槽的半径与圆心角从而更好地设计第四转动轴心线C4的位置。
当然在其他实施方式中，第一圆弧槽3150也可以设于第一转动机构20的连接件23上，第一圆弧轨3151也可设于导向部315上。
可选地，支撑部313的非支撑面311在远离支架10的一端设有导向部315，导向部315为弧形块。进一步可选地，导向部315朝向第一转动机构20的连接件23的一侧开设有第一圆弧槽3150，且第一圆弧槽3150的相对两端贯穿导向部315靠近支撑部313的一侧表面、以及导向部315远离支架10的一侧表面。
可选地，在一些实施方式中，支撑部313的非支撑面311在对应第一转动机构20的连接件23的相对两端分别设有导向部315，两个导向部315面对面设置的表面设有第一圆弧槽3150，两个第一圆弧槽3150的轴心线共线。第一转动机构20的连接件23的相对两侧分别设有第一圆弧轨3151，两个第一圆弧轨3151可分别对应插设与第一圆弧槽3150内。
值得注意的是，本实施方式及后文仅以折叠装置1的一半结构进行示意性说明，换句话说仅以折叠装置1的右半部分的结构进行示意性说明，例如本实施方式仅以位于支架10右侧的第一支撑件31与第一转动机构20的连接件23进行示意性说明，至于位于支架10左侧的第二支撑件31'与第二转动机构20'的连接件23可与本实施方式的第一支撑件31与第一转动机构20的连接件23做同样理解，本实施方式在此不再赘述。
请一并参考图11-图12，图11为本申请一实施方式中第一支撑件与第一从动件的配合示意图。图12为图11所示的第一支撑件与第一从动件的分解示意图。本实施方式中，第一支撑件31包括支撑部313与转动部314，支撑部313具有用于支撑屏幕的支撑面310，转动部314固设于与支撑面310相背离的一侧表面，第一从动件71远离支架10的一端与转动部314之间通过第一转动轴3142与第一转动孔3143配合连接，第一转动轴3142设于第一从动件71与转动部314中的一者，第一转动孔3143设于第一从动件71与转动部314中的另一者。
第一支撑件31还可包括支撑部313与转动部314，关于支撑部313本申请上文已进行了详细介绍，本实施方式在此不再赘述。转动部314用于与第一从动件71进行配合连接。其中转动部314设于支撑部313的非支撑面311上。可选地，转动部314与导向部315设于第一转动机构20的连接件23的相对两侧。即第一转动机构20的连接件23的一侧与导向部315配合连接，另一侧与转动部314配合连接。
支撑部313与转动部314可以为一体式结构，也可以为分体式结构。当支撑部313与转动部314为一体式结构时，支撑部313与转动部314是通过一道工序制备而成，只不过为了便于理解，人为将支撑部313与转动部314进行了不同的命名。当支撑部313与转动部314为分体式结构时，支撑部313与转动部314是分开制备的，然后再通过各种方法连接在一起。本实施方式仅以支撑部313与转动部314为一体式结构进行示意性说明。
可选地，支撑部313、导向部315、及转动部314三者可均为一体式结构，即支撑部313、导向部315、及转动部314均是通过一道工序制备而成的。或者三者均为分体式结构，即支撑部313、导向部315、及转动部314均为分开制备的，然后再通过各种方法结合到一起。或者三者中的部分为一体式结构，其余的部分为分体式结构，即支撑部313、导向部315、及转动部314中的部分部件是一道工序制备而成的，其余的部件是分开制备的，然后再通过各种方法将其结合到一起。
因此上述提及的第一支撑件31与第一从动件71转动连接即为转动部314与第一从动件71转动连接。具体地，本实施方式可使转动部314与第一从动件71之间通过第一转动轴3142与第一转动孔3143配合连接，换句话说是转动部314与第一从动件71之间通过第一转动轴3142与第一转动孔3143配合连接，第一转动轴3142的轴心线与第一转动孔3143的轴心线相重合，且第一转动轴3142的轴心线与转动部314和第一从动件71之间的第三转动轴心线C3重合，从而实现转动部314转动连接第一从动件71。例如当第一转动轴3142设于转动部314上时第一转动孔3143设于第一从动件71，或者当第一转动轴3142设于第一从动件71上时第一转动孔3143设于转动部314上。本实施方式仅以第一转动轴3142设于第一从动件71上第一转动孔3143设于转动部314进行示意性说明。具体地，第一转动轴3142凸设于第一从动件71的至少一侧，两个转动部314设于第一从动件71的相对两侧，且两个转动部314上均开设有第一转动孔3143，第一转动轴3142插设于第一转动孔3143内使第一转动轴3142能够在第一转动孔3143内进行转动，从而使转动部314相对第一从动件71进行转动。
当然在其他实施方式中第一转动轴3142也可设于两个转动部314上，第一转动孔3143设于第一从动件71的相对两侧，第一转动轴3142插设于第一转动孔3143内使第一转动轴3142能够在第一转动孔3143内进行转动，从而使转动部314相对第一从动件71进行转动。
值得注意的是，本实施方式提及的第一转动孔3143可以为通孔或为盲孔。其中通孔指的是第一转动孔3143同时贯穿结构件相对的两侧表面，盲孔指的是第一转动孔3143只贯穿结构件的一侧表面，因此盲孔也可称之为槽。
可选地，在一些实施方式中，设在第一从动件71相对两侧的两个转动部314关于第一从动件71呈轴对称设置。在其他实施方式中两个转动部314也可以为非对称式设置。
另外，第一转动轴3142与转动部314或第一从动件71可以为固定连接，也可以为转动连接。例如本实施方式中第一转动轴3142设于第一从动件71上，第一转动轴3142可固设于第一从动件71上使第一转动轴3142与第一从动件71保持相对静止，第一转动轴3142插设于第一转动孔3143内并相对第一转动孔3143转动，从而使转动部314相对第一从动件71转动。或者第一转动轴3142也可转动连接于第一从动件71上，使第一转动轴3142与第一从动件71保持相对转动，这样依然可以使第一转动轴3142在第一转动孔3143内转动，从而使转动部314相对第一从动件71转动。例如第一从动件71具有贯穿其相对两侧的第一收容孔7100，第一转动轴3142贯穿第一收容孔7100，且第一转动轴3142的相对两端均凸出于转动部314的相对两侧。
可选地，当第一转动轴3142固设于第一从动件71上时第一转动轴3142与第一从动件71可以为一体式结构，也可以为分体式结构。当第一转动轴3142与第一从动件71为一体式结构时，第一转动轴3142与第一从动件71是通过一道工序制备而成，只不过为了便于理解，人为将第一转动轴3142与第一从动件71进行了不同的命名。当第一转动轴3142与第一从动件71为分体式结构时，第一转动轴3142与第一从动件71是分开制备的，然后再通过各种方法例如插接在一起。本实施方式仅以第一转动轴3142与第一从动件71为分体式结构进行示意性说明。
请参考图13，图13为本申请一实施方式中支架、第一从动件、第一转动机构的第一转动件、及第二转动件的截面示意图。本实施方式中，支架10具有用于背离屏幕的底面102，第一从动件71与支架10之间的第三转动轴线C33相较于第一转动机构20的第一转动件21与支架10之间的第一转动轴线C11、及第一转动机构20的第二转动件22与支架10之间的第二转动轴线C22更远离底面102。
从上述内容可知支架10具有顶面101与底面102，其中顶面101即为图13中支架10的上表面，底面102即为图13中支架10的下表面，底面102较顶面101更远离屏幕。上述已提及可通过第三转动轴心线C3与第四转动轴心线C4之间距离的变化来使第一支撑件31相对第一转动机构20的连接件23转动从而形成水滴形状。其中第三转动轴心线C3位置的变化是通过第一从动件71相对支架10转动实现的，第四转动轴心线C4位置的变化是通过第一转动机构20的连接件23相对支架10转动实现的，而第一转动机构20的连接件23的转动又受到第一转动机构20的第一转动件21与第一转动机构20的第二 转动件22的制约。因此本实施方式通过设计第一从动件71、第一转动机构20的第一转动件21、及第一转动机构20的第二转动件22分别和支架10之间形成转动轴线的位置来实现上述运动。
具体地，第一转动机构20的第一转动件21可相对支架10转动，因此第一转动机构20的第一转动件21与支架10之间具有第一转动轴线C11。第一转动机构20的第二转动件22可相对支架10转动，因此第一转动机构20的第二转动件22与支架10之间具有第二转动轴线C22。第一从动件71也可相对支架10转动，因此第一从动件71与支架10之间具有第三转动轴线C33。本实施方式可使第三转动轴线C33相较于第一转动轴线C11与第二转动轴线C22远离底面102。换句话说，在垂直于底面102的方向上，即图13中的竖直方向上，第三转动轴线C33相较于第一转动轴线C11与第二转动轴线C22更靠上。采用上述设计便可使得当第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、及第一从动件71相对支架10转动90°后，第三转动轴心线C3与第四转动轴心线C4实现上述实施方式提及的运动轨迹，即在平行于支撑面310的方向上，第一支撑件31与第一从动件71之间的第三转动轴心线C3、及第一支撑件31与第一转动机构20的连接件23之间的第四转动轴心线C4之间的距离逐渐减小。在垂直于支撑面310的方向上，第一支撑件31与第一从动件71之间的第三转动轴心线C3、及第一支撑件31与第一转动机构20的连接件23之间的第四转动轴心线C4之间的距离逐渐增加。进而驱动第一支撑件31相对第一转动机构20的连接件23转动从而形成水滴形。至于第一转动轴线C11与第二转动轴线C22之间的位置关系，本实施方式在此并不进行限定。
请一并参考图13-图14，图14为图1所示的折叠装置的俯视图。本实施方式中，第一支撑件31与第二支撑件31'关于支架10的中线呈轴对称设置，第三转动轴线C33相较于第一转动轴线C11与第二转动轴线C22更靠近中线。
支架10具有沿两个第二侧面104的排列方向上的中线(如图13-图14中的C所示)，第一支撑件31与第二支撑件31'关于支架10呈轴对称设置，甚至两个转动机构20中的第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、及第一转动机构20的连接件23也可关于中线呈轴对称设置。至于第一从动件71与第二从动件71'可相对中线对称设计，也可相对中线非对称设计。除了在竖直方向上三个转动轴线具有一定的位置关系外，本实施方式还可在水平方向使三个转动轴线具有一定的位置关系。具体地，第三转动轴线C33相较于第一转动轴线C11与第二转动轴线C22更靠近中线。换句话说，在图13中的水平方向上，第三转动轴线C33更靠内，第一转动轴线C11与第二转动轴线C22更靠外。这样可使得第一从动件71与支架10相配合的尺寸更大，从而使第一从动件71更好地与支架10进行转动，防止第一从动件71与支架10分离，提高了第一从动件71与支架10的稳定性。并且第三转动轴线C33相较于第一转动轴线C11与第二转动轴线C22更靠近中线可进一步使第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、及第一从动件71相对支架10转动90°后，第三转动轴心线C3与第四转动轴心线C4实现上述实施方式提及的运动轨迹，进而驱动第一支撑件31相对第一转动机构20的连接件23转动从而形成水滴形。
请再次参考图14，本实施方式中，第一转动机构20的第一转动件21与支架10之间的第一转动轴线C11平行或重合于于第一转动机构20的第二转动件22与支架10之间的第二转动轴线C22。
首先两个转动轴线相互平行可使第一转动机构20的连接件23顺利转动，且第一转动机构20的连接件23在转动时带动第一转动机构20的第一转动件21与第一转动机构20的第二转动件22均相对支架10转动，防止转动时出现卡死等问题。其次，可使折叠装置1在静止状态下，例如展开状态或折叠状态，或者展开状态与折叠状态之间的任意状态时使第一转动机构20的第一转动件21与第一转动机构20的第二转动件22处于静止状态，防止支架10相对第一转动机构20的第一转动件21与第一转动机构20的第二转动件22进行转动，提高折叠装置1的稳定性，使折叠装置1在某一状态下时实现悬停、自锁等功能。
可选地，在一些实施方式中，在水平方向上第一转动轴线C11相较于第二转动轴线C22更靠内，即第一转动轴线C11相较于第二转动轴线C22更靠近支架10的中线。或者第一转动轴线C11相较于第二 转动轴线C22更靠外，即第一转动轴线C11相较于第二转动轴线C22更远离支架10的中线。在其他实施方式中，在竖直方向上，第一转动轴线C11相较于第二转动轴线C22更靠近支架10的底面102，即第一转动轴线C11相较于第二转动轴线C22更靠下。或者第一转动轴线C11相较于第二转动轴线C22更远离支架10的底面102，即第一转动轴线C11相较于第二转动轴线C22更靠上。本实施方式仅以第一转动轴线C11相较于第二转动轴线C22更靠左上进行示意性说明。当然在其他实施方式中第一转动轴线C11与第二转动轴线C22也可以重合设置，不影响折叠装置1的运动过程。
另外，关于第一转动轴线C11、第二转动轴线C22、及第三转动轴线C33与支架10的位置，三个转动轴线可位于支架10内，或者三个转动轴线也可位于支架10外，或者三个转动轴线部分。
请一并参考图15-图17，图15为本申请一实施方式中第一转动机构的第一转动件、第二转动件、第一从动件、及部分支架的配合示意图。图16为本申请一实施方式中第一转动机构的第一转动件、第二转动件、第一从动件、及支架的分解示意图。图17为图16所示的支架另一视角的分解示意图。本实施方式中，第一转动机构20的第一转动件21靠近支架10的一端与支架10通过第二圆弧轨2100与第二圆弧槽2101配合连接，第二圆弧轨2100设于第一转动机构20的第一转动件21与支架10中的一者，第二圆弧槽2101设于第一转动机构20的第一转动件21与支架10中的另一者。第一转动机构20的第二转动件22靠近支架10的一端与支架10之间通过第三圆弧轨2200与第三圆弧槽2201配合连接，第三圆弧轨2200设于第一转动机构20的第二转动件22与支架10中的一者，第三圆弧槽2201设于第一转动机构20的第二转动件22与支架10中的另一者。
在本实施方式中转动件与支架10均可通过圆弧轨与圆弧槽的配合形式来实现转动连接。具体地，第一转动机构20的第一转动件21与支架10之间通过第二圆弧槽2101与第二圆弧轨2100配合连接。例如当第二圆弧轨2100设于第一转动机构20的第一转动件21上时第二圆弧槽2101设于支架10上，当第二圆弧槽2101设于第一转动机构20的第一转动件21上时第二圆弧轨2100设于支架10上。本实施方式仅以第二圆弧轨2100设于第一转动机构20的第一转动件21上第二圆弧槽2101设于支架10上进行示意性说明。具体地，支架10上设有圆弧形的槽体，第一转动机构20的第一转动件21靠近支架10的一端设有对应圆弧槽体形状的圆弧形的块体，第二圆弧轨2100可设于第二圆弧槽2101内并抵接第二圆弧槽2101的内壁，且第二圆弧槽2101的轴心线与第二圆弧轨2100的轴心线共线，第二圆弧槽2101的轴心线与第一转动机构20的第一转动件21和支架10之间的第一转动轴线C11共线，使得第一转动机构20的第一转动件21可相对支架10进行转动。
至于第二圆弧槽2101与第二圆弧轨2100的尺寸与弧度可根据所需的第一转动轴线C11的位置进行设计。另外，采用圆弧槽与圆弧柜的设计方式可使得第一转动轴线C11的位置既可在支架10内可也位于支架10外，例如可根据改变圆弧槽的半径与圆心角从而更好地设计第一转动轴线C11的位置。
当然在其他实施方式中，第二圆弧槽2101也可以设于第一转动机构20的第一转动件21上，第二圆弧轨2100也可设于支架10上。
同理，第一转动机构20的第二转动件22与支架10之间通过第三圆弧槽2201与第三圆弧轨2200配合连接。当第三圆弧轨2200设于第一转动机构20的第二转动件22上时第三圆弧槽2201设于支架10上，当第三圆弧槽2201设于第一转动机构20的第二转动件22上时第三圆弧轨2200设于支架10上。本实施方式仅以第三圆弧轨2200设于第一转动机构20的第二转动件22上第三圆弧槽2201设于支架10上进行示意性说明。具体地，支架10上设有圆弧形的槽体，第一转动机构20的第二转动件22靠近支架10的一端设有对应圆弧槽体形状的圆弧形的块体，第三圆弧轨2200可设于第三圆弧槽2201内并抵接第三圆弧槽2201的内壁，且第三圆弧槽2201的轴心线与第三圆弧轨2200的轴心线共线，第三圆弧槽2201的轴心线与第一转动机构20的第二转动件22和支架10之间的第二转动轴线C22共线，使得第一转动机构20的第二转动件22可相对支架10进行转动。
至于第三圆弧槽2201与第三圆弧轨2200的尺寸与弧度可根据所需的第二转动轴线C22的位置进行设计。另外，采用圆弧槽与圆弧柜的设计方式可使得第二转动轴线C22的位置既可在支架10内可也位 于支架10外，例如可根据改变圆弧槽的半径与圆心角从而更好地设计第二转动轴线C22的位置。
当然在其他实施方式中，第三圆弧槽2201也可以设于第一转动机构20的第二转动件22上，第三圆弧轨2200也可设于支架10上。
请再次参考图15-图16，本实施方式中，第一从动件71靠近支架10的一端与支架10之间通过第四圆弧轨7101与第四圆弧槽7102配合连接，第四圆弧轨7101设于第一从动件71与支架10中的一者，第四圆弧槽7102设于第一从动件71与支架10中的另一者。
至于第一从动件71与支架10之间也可通过圆弧槽与圆弧轨的配合形式实现转动连接。具体地，第一从动件71与支架10之间通过第四圆弧槽7102与第四圆弧轨7101配合连接。当第四圆弧轨7101设于第一从动件71上时第四圆弧槽7102设于支架10上，当第四圆弧槽7102设于第一从动件71上时第四圆弧轨7101设于支架10上。本实施方式仅以第四圆弧轨7101设于第一从动件71上第四圆弧槽7102设于支架10上进行示意性说明。具体地，支架10上设有圆弧形的槽体，第一从动件71靠近支架10的一端设有对应圆弧槽体形状的圆弧形的块体，第四圆弧轨7101可设于第四圆弧槽7102内并抵接第四圆弧槽7102的内壁，且第四圆弧槽7102的轴心线与第四圆弧轨7101的轴心线共线，第四圆弧槽7102的轴心线与第一从动件71和支架10之间的第三转动轴线C33共线，使得第一从动件71可相对支架10进行转动。
至于第四圆弧槽7102与第四圆弧轨7101的尺寸与弧度可根据所需的第三转动轴线C33的位置进行设计。另外，采用圆弧槽与圆弧柜的设计方式可使得第三转动轴线C33的位置既可在支架10内可也位于支架10外，例如可根据改变圆弧槽的半径与圆心角从而更好地设计第三转动轴线C33的位置。
当然在其他实施方式中，第四圆弧槽7102也可以设于第一从动件71上，第四圆弧轨7101也可设于支架10上。
另外，通过各个圆弧槽与圆弧轨的形状设计便可实现上述三个转动轴线的位置关系。例如在一些实施方式中可使第三圆弧槽2201相较于第一圆弧槽3150与第二圆弧槽2101的曲率更平缓，或者说圆心角更大，使第三转动轴线C33更靠上，从而使第三转动轴心线C3与第四转动轴心线C4实现上述实施方式提及的运动轨迹，进而驱动第一支撑件31相对第一转动机构20的连接件23转动从而形成水滴形。
并且由于本实施方式将第三圆弧槽2201与第三圆弧轨2200设计的更平缓，也可以理解为更窄，因此第一从动件71与支架10接触的面积较小。基于此在一些实施方式中增加第三圆弧槽2201与第三圆弧轨2200在水平方向上的尺寸，即使第三转动轴线C33更靠内，从而增加第一从动件71与支架10的接触面积，提高第一从动件71与支架10的结构稳定性，防止第一从动件71与支架10相分离。
请再次参考图15，本实施方式中，第一支撑件31与第二支撑件31'关于支架10的中线呈轴对称设置，第一转动机构20的第一转动件21靠近支架10的一端与第二转动机构20'的第一转动件21靠近支架10的一端关于中线呈轴对称设置，第一转动机构20的第二转动件22靠近支架10的一端与第二转动机构20'的第二转动件22靠近支架10的一端关于中线呈轴对称设置，第一从动件71靠近支架10的一端与第二从动件71'靠近支架10的一端关于中线交错设置。
上述已提及第一支撑件31与第二支撑件31'、第一转动机构20的第一转动件21与第二转动机构20'的第一转动件21、第一转动机构20的第二转动件22与第二转动机构20'的第二转动件22、甚至第一转动机构20的连接件23与第二转动机构20'的连接件23均可相对于支架10的中线呈轴对称设置。至于第一从动件71与第二从动件71'上述提及可以增加第三圆弧轨2200在水平方向上的尺寸，即增加第一从动件71的尺寸，因此本实施方式可使第一从动件71与第二从动件71'靠近支架10的一端交错设置。其中交错设置指的是第一从动件71与第二从动件71'并非沿中线呈轴对称设置，而是沿着中线的方向上层叠设置，并且沿着中线的方向上第一从动件71与第二从动件71'的端部至少部分重叠。这样可更好地设计较大尺寸的第一从动件71从而实现上述的运动轨迹。
请参考图18，图18为本申请一实施方式中支架、第一转动机构的第一转动件、第二转动件的正视图。本实施方式中，第一转动轴心线C1相较于第二转动轴心线C2远离支架10。
上述内容已提及可使第一转动机构20的第一转动件21与第一转动机构20的连接件23之间的第一转动轴心线C1平行于第一转动机构20的第二转动件22与第一转动机构20的连接件23之间的第二转动轴心线C2，从而防止支架10相对第一转动机构20的第一转动件21与第一转动机构20的第二转动件22转动，保证支架10的稳定性。本申请同样提供了不同的实施方式来使第一转动轴心线C1平行第二转动轴心线C2。具体地，本实施方式可使第一转动轴心线C1相较于第二转动轴心线C2远离支架10，换句话说在图18中的水平方向上，第一转动轴心线C1更靠外，第二转动轴心线C2更靠内从而实现第一转动轴心线C1平行第二转动轴心线C2。在其他实施方式中也可以设置成第一转动轴心线C1相较于第二转动轴心线C2靠近支架10。
请再次参考图18，本实施方式中，第一支撑件31具有支撑面310，第一转动轴心线C1相较于第二转动轴心线C2更靠近支撑面310。
除了可在水平方向上使第一转动轴心线C1更靠外之外，本实施方式还可使第一转动轴心线C1相较于第二转动轴心线C2更靠近支撑面310。换句话说在图18中的竖直方向上第一转动轴心线C1更靠上，第二转动轴心线C2更靠下，从而进一步增加第一转动轴心线C1与第二转动轴心线C2之间的距离，当两个轴心线之间的距离增加时可进一步提高第一转动机构20的连接件23的稳定性，防止第一转动机构20的连接件23相对第一转动机构20的第一转动件21与第一转动机构20的第二转动件22转动。并且使第一转动轴心线C1靠右上设置，第二转动轴心线C2靠近左下设置可使两个轴心线在相同距离的前提下减小折叠装置1的尺寸，进一步实现折叠装置1的小型化。
另外，关于位于支架10同一侧的第一从动件71、第一转动机构20的第一转动件21、及第一转动机构20的第二转动件22可沿着支架10的中线层叠设置，至于第一转动机构20的第一转动件21与第一转动机构20的第二转动件22的位置关系，例如第一从动件71、第一转动机构20的第一转动件21、及第一转动机构20的第二转动件22具体设置在支架10的何处、或者第一转动机构20的第一转动件21与第一转动机构20的第二转动件22哪个更靠近第一从动件71本实施方式在此并不进行限定。本实施方式仅以第一转动机构20的第一转动件21相较于第一转动机构20的第二转动件22远离第一从动件71进行示意性说明。
请一并参考图19-图20，图19为本申请一实施方式中第一转动机构的第一转动件、第二转动件、及连接件的配合示意图。图20为图19所示的第一转动机构的第一转动件、第二转动件、及连接件的分解示意图。本实施方式中，第一转动机构20的第一转动件21远离支架10的一端与第一转动机构20的连接件23之间通过第二转动轴2110与第二转动孔2111配合连接，第二转动轴2110设于第一转动机构20的第一转动件21与第一转动机构20的连接件23中的一者，第二转动孔2111设于第一转动机构20的第一转动件21与第一转动机构20的连接件23中的另一者。第一转动机构20的第二转动件22远离支架10的一端与第一转动机构20的连接件23之间通过第三转动轴2210与第三转动孔2211配合连接，第三转动轴2210设于第一转动机构20的第二转动件22与第一转动机构20的连接件23中的一者，第三转动孔2211设于第一转动机构20的第二转动件22与第一转动机构20的连接件23中的另一者。
第一转动机构20的第一转动件21与第一转动机构20的第二转动件22和第一转动机构20的连接件23配合连接的一端可采用转动轴与转动孔的配合形式。具体地，第一转动机构20的第一转动件21与第一转动机构20的连接件23之间可通过第二转动轴2110与第二转动孔2111配合连接，第二转动轴2110的轴心线与第二转动孔2111的轴心线相重合，且第二转动轴2110的轴心线与第一转动机构20的第一转动件21和第一转动机构20的连接件23之间的第一转动轴心线C1重合，从而实现第一转动机构20的第一转动件21转动连接第一转动机构20的连接件23。例如当第二转动轴2110设于第一转动机构20的连接件23上时第二转动孔2111设于第一转动机构20的第一转动件21，或者当第二转动轴2110设于第一转动机构20的第一转动件21上时第二转动孔2111设于第一转动机构20的连接件23上。本实施方式仅以第二转动轴2110设于第一转动机构20的第一转动件21上第二转动孔2111设于第一转动机构20的连接件23进行示意性说明。具体地，第二转动轴2110凸设于第一转动机构20的第一转动件 21的相对两侧，第一转动机构20的连接件23上设有第二转动孔2111，第二转动轴2110插设于第二转动孔2111内使第二转动轴2110能够在第二转动孔2111内进行转动，从而使第一转动机构20的第一转动件21相对第一转动机构20的连接件23进行转动。当然在其他实施方式中第二转动轴2110也可设于第一转动机构20的连接件23上，第二转动孔2111设于第一转动机构20的第一转动件21的相对两侧。
值得注意的是，本实施方式提及的第二转动孔2111可以为通孔或为盲孔。其中通孔指的是第二转动孔2111同时贯穿结构件相对的两侧表面，盲孔指的是第二转动孔2111只贯穿结构件的一侧表面，因此盲孔也可称之为槽。
另外，第二转动轴2110与第一转动机构20的连接件23或第一转动机构20的第一转动件21可以为固定连接，也可以为转动连接。例如本实施方式中第二转动轴2110设于第一转动机构20的第一转动件21上，第二转动轴2110可固设于第一转动机构20的第一转动件21上使第二转动轴2110与第一转动机构20的第一转动件21保持相对静止，第二转动轴2110插设于第二转动孔2111内并相对第二转动孔2111转动，从而使第一转动机构20的连接件23相对第一转动机构20的第一转动件21转动。或者第二转动轴2110也可转动连接于第一转动机构20的第一转动件21上，使第二转动轴2110与第一转动机构20的第一转动件21保持相对转动，这样依然可以使第二转动轴2110在第二转动孔2111内转动，从而使第一转动机构20的连接件23相对第一转动机构20的第一转动件21转动。例如第一转动机构20的第一转动件21具有贯穿其相对两侧的第二收容孔2112，第二转动轴2110贯穿第二收容孔2112，且第二转动轴2110的相对两端均凸出于第一转动机构20的第一转动件21的相对两侧。
可选地，当第二转动轴2110固设于第一转动机构20的第一转动件21上时第二转动轴2110与第一转动机构20的第一转动件21可以为一体式结构，也可以为分体式结构。当第二转动轴2110与第一转动机构20的第一转动件21为一体式结构时，第二转动轴2110与第一转动机构20的第一转动件21是通过一道工序制备而成，只不过为了便于理解，人为将第二转动轴2110与第一转动机构20的第一转动件21进行了不同的命名。当第二转动轴2110与第一转动机构20的第一转动件21为分体式结构时，第二转动轴2110与第一转动机构20的第一转动件21是分开制备的，然后再通过各种方法例如插接在一起。本实施方式仅以第二转动轴2110与第一转动机构20的第一转动件21为分体式结构进行示意性说明。
同理，第一转动机构20的第二转动件22与第一转动机构20的连接件23之间可通过第三转动轴2210与第三转动孔2211配合连接，第三转动轴2210的轴心线与第三转动孔2211的轴心线相重合，且第三转动轴2210的轴心线与第一转动机构20的第二转动件22和第一转动机构20的连接件23之间的第二转动轴心线C2重合，从而实现第一转动机构20的第二转动件22转动连接第一转动机构20的连接件23。例如当第三转动轴2210设于第一转动机构20的连接件23上时第三转动孔2211设于第一转动机构20的第二转动件22，或者当第三转动轴2210设于第一转动机构20的第二转动件22上时第三转动孔2211设于第一转动机构20的连接件23上。本实施方式仅以第三转动轴2210设于第一转动机构20的第二转动件22上第三转动孔2211设于第一转动机构20的连接件23进行示意性说明。具体地，第三转动轴2210凸设于第一转动机构20的第二转动件22的相对两侧，第一转动机构20的连接件23上设有第三转动孔2211，第三转动轴2210插设于第三转动孔2211内使第三转动轴2210能够在第三转动孔2211内进行转动，从而使第一转动机构20的第二转动件22相对第一转动机构20的连接件23进行转动。当然在其他实施方式中第三转动轴2210也可设于第一转动机构20的连接件23上，第三转动孔2211设于第一转动机构20的第二转动件22的相对两侧。
值得注意的是，本实施方式提及的第三转动孔2211可以为通孔或为盲孔。其中通孔指的是第三转动孔2211同时贯穿结构件相对的两侧表面，盲孔指的是第三转动孔2211只贯穿结构件的一侧表面，因此盲孔也可称之为槽。
另外，第三转动轴2210与第一转动机构20的连接件23或第一转动机构20的第二转动件22可以为固定连接，也可以为转动连接。例如本实施方式中第三转动轴2210设于第一转动机构20的第二转动 件22上，第三转动轴2210可固设于第一转动机构20的第二转动件22上使第三转动轴2210与第一转动机构20的第二转动件22保持相对静止，第三转动轴2210插设于第三转动孔2211内并相对第三转动孔2211转动，从而使第一转动机构20的连接件23相对第一转动机构20的第二转动件22转动。或者第三转动轴2210也可转动连接于第一转动机构20的第二转动件22上，使第三转动轴2210与第一转动机构20的第二转动件22保持相对转动，这样依然可以使第三转动轴2210在第三转动孔2211内转动，从而使第一转动机构20的连接件23相对第一转动机构20的第二转动件22转动。例如第一转动机构20的第二转动件22具有贯穿其相对两侧的第三收容孔2212，第三转动轴2210贯穿第三收容孔2212，且第三转动轴2210的相对两端均凸出于第一转动机构20的第二转动件22的相对两侧。
可选地，当第三转动轴2210固设于第一转动机构20的第二转动件22上时第三转动轴2210与第一转动机构20的第二转动件22可以为一体式结构，也可以为分体式结构。当第三转动轴2210与第一转动机构20的第二转动件22为一体式结构时，第三转动轴2210与第一转动机构20的第二转动件22是通过一道工序制备而成，只不过为了便于理解，人为将第三转动轴2210与第一转动机构20的第二转动件22进行了不同的命名。当第三转动轴2210与第一转动机构20的第二转动件22为分体式结构时，第三转动轴2210与第一转动机构20的第二转动件22是分开制备的，然后再通过各种方法例如插接在一起。本实施方式仅以第三转动轴2210与第一转动机构20的第二转动件22为分体式结构进行示意性说明。
请再次参考图15-图17，本实施方式中，支架10包括分体式结构的第一子支架110与第二子支架120，第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、第一从动件71、及第二从动件71'夹设于第一子支架110与第二子支架120之间、并通过第一子支架110与第二子支架120实现转动连接。
本实施方式的支架10是由分体式的第一子支架110与第二子支架120构成，即第一子支架110与第二子支架120是分开制备的，然后再通过各种方法例如粘接、卡接、或者螺钉连接等方法装配到一起。第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、第一从动件71、及第二从动件71'可夹设于第一子支架110与第二子支架120之间，利用第一子支架110与第二子支架120相互配合来和第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、第一从动件71、及第二从动件71'实现转动连接。例如上述内容已提及本申请以第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、第一从动件71、及第二从动件71'的一端为转动轴进行示意性说明，因此支架10上则相对应设有第二圆弧槽2101、第三圆弧槽2201、以及第四圆弧槽7102。因此可在第一子支架110上开设三个容置空间111，并在第二子支架120靠近第一子支架110的一侧且对应每个容置空间111处设置凸起121，当第一子支架110与第二子支架120装配到一起后，每个容置空间111的第一子支架110、第二子支架120、以及凸起121共同围设形成相对应的圆弧槽。另外还可在第二子支架120上凸起121的相对两侧开设连通容置空间111的过孔122，用于避让转动件与第一从动件71，防止第二子支架120与第一转动机构20的第一转动件21、第一转动机构20的第二转动件22、第一从动件71、及第二从动件71'发生干涉。
在其他实施方式中也可以设计成一体式结构的支架10，即第一子支架110与第二子支架120为不可分割的结构形式。
除了上述结构件之外折叠装置1也可包括同步机构或悬停机构，同步机构用于使当支架10一侧的第一转动机构20的连接件23转动从而带动第一支撑件31运动时，可通过同步机构使支架10另一侧的第一支撑件31做同步且反向的运动，实现第一支撑件31与第二支撑件31'的同步折叠与同步展开。悬停机构用于使当第一转动机构20的连接件23转动一定角度时此时若撤去外力，第一转动机构20的连接件23可保持固定不动实现静止状态，第一转动机构20的连接件23不会自动回落。至于同步机构与悬停机构的具体结构本申请在此不进行展开介绍。另外本申请除了提供了一种折叠装置1外，还提供了一种利用该折叠装置1装配而成的壳体组件2。
第二转动机构20'、第二支撑件31'、以及第二从动件71'的相关结构与位置关系可与第一转动机构20、第一支撑件31、以及第一从动件71做同样的理解。例如第二支撑件31'还相对第二转动机构20'的连接件23转动，第二支撑件31'还相对第二转动机构20'的连接件23转动，以使第一支撑件31与第二支撑件31'处于完全相互折叠状态时第一支撑件31与第二支撑件31'均位于支架10的同一侧，且第一支撑件31与第二支撑件31'在远离支架10一端之间的距离小于或等于第一支撑件31与第二支撑件31'在靠近支架10一端之间的距离。

本实施方式中，第二转动机构20'的第一转动件21与支架10之间的第一转动轴线C11平行或重合于于第二转动机构20'的第二转动件22与支架10之间的第二转动轴线C22。
本实施方式中，第二转动机构20'的第一转动件21靠近支架10的一端与支架10通过第二圆弧轨2100与第二圆弧槽2101配合连接，第二圆弧轨2100设于第二转动机构20'的第一转动件21与支架10中的一者，第二圆弧槽2101设于第二转动机构20'的第一转动件21与支架10中的另一者。第二转动机构20'的第二转动件22靠近支架10的一端与支架10之间通过第三圆弧轨2200与第三圆弧槽2201配合连接，第三圆弧轨2200设于第二转动机构20'的第二转动件22与支架10中的一者，第三圆弧槽2201设于第二转动机构20'的第二转动件22与支架10中的另一者。

请一并参考图21-图29，图21为本申请一实施方式中壳体组件处于展开状态时的立体结构示意图。图22为图21所示的壳体组件的部分结构爆炸图。图23-图25分别为图21所示的壳体组件不同部位的截面示意图。图26为本申请一实施方式中壳体组件处于折叠状态时的立体结构示意图。图27-图29分别为图26所示的壳体组件不同部位的截面示意图。
本实施方式提供了一种壳体组件2，所述壳体组件2包括第一壳体40、第二壳体40'、及如本申请上述实施方式提供的折叠装置1，所述第一壳体40与所述第二壳体40'的至少部分设于所述折叠装置1的相对两侧，所述第一壳体40连接所述折叠装置1的所述第一转动机构20的连接件23，所述第二壳体40'连接所述折叠装置1的所述第二转动机构20'的连接件23。所述第一转动机构20的连接件23以及所述第二转动机构20'的连接件23转动时，所述第一壳体40与所述第二壳体40'转动在展开状态和折叠状态之间切换。
壳体组件2是一种组合式的部件，即壳体组件2包含了至少两种部件。在本实施方式中壳体组件2主要包括第一壳体40与第二壳体40'与上述实施方式介绍的折叠装置1。壳体主要用于装设和承载结构件，例如可在壳体上承载屏幕，可在壳体内设置例如电路板、电池、摄像头等结构件。因此第一壳体40与第二壳体40'主要起装设、保护等作用。在一些实施方式中，第一壳体40与第二壳体40'的表面还可充当外观面，因此可对第一壳体40与第二壳体40'的表面进行相应地设计，使第一壳体40与第二壳体40'具有独特的外面效果。本实施方式并不对第一壳体40与第二壳体40'的形状、材质、结构等参数进行限定，只要能实现装设与保护的作用即可。例如第一壳体40与第二壳体40'的材质可以为全部均为金属，或者全部均为塑料，或者部分为金属，部分为塑料。
折叠装置1的连接件23可固设于壳体40，即所述第一壳体40连接所述折叠装置1的所述第一转动机构20的连接件23，所述第二壳体40'连接所述折叠装置1的所述第二转动机构20'的连接件23。换句话说，第一壳体40与第一转动机构20的连接件23可以为一体式结构，也可以为分体式结构。当第一壳体40与第一转动机构20的连接件23为一体式结构时，第一壳体40与第一转动机构20的连接件23是通过一道工序制备而成，只不过为了便于理解，人为将第一壳体40与第一转动机构20的连接件23进行了不同的命名。当第一壳体40与第一转动机构20的连接件23为分体式结构时，第一壳体40与第一转动机构20的连接件23是分开制备的，然后再通过各种方法例如螺钉连接、粘接、卡接等方式组装在一起。本实施方式仅以第一壳体40与第一转动机构20的连接件23为分体式结构进行示意性说明。
第二壳体40'与第二转动机构20'的连接件23可以为一体式结构，也可以为分体式结构。当第二壳体40'与第二转动机构20'的连接件23为一体式结构时，第二壳体40'与第二转动机构20'的连接件23是通过一道工序制备而成，只不过为了便于理解，人为将第二壳体40'与第二转动机构20'的连接件23进行了不同的命名。当第二壳体40'与第二转动机构20'的连接件23为分体式结构时，第二壳体40'与第二转动机构20'的连接件23是分开制备的，然后再通过各种方法例如螺钉连接、粘接、卡接等方式组装在一起。本实施方式仅以第二壳体40'与第二转动机构20'的连接件23为分体式结构进行示意性说明。
第一壳体40与第二壳体40'的至少部分设于折叠装置1的相对两侧。在一些实施方式中第一壳体40与第二壳体40'的全部可均设于折叠装置1的相对两侧，例如每个第一壳体40设于支架10的第一侧面103。在其他实施方式中第一壳体40与第二壳体40'的部分设于折叠装置1的相对两侧，至于其他部分则设于折叠装置1的其他侧边。例如每个第一壳体40的部分设于支架10的第一侧面103，其余部分设于支架10的底面102。
所述第一转动机构20的连接件23以及所述第二转动机构20'的连接件23转动时，所述第一壳体40与所述第二壳体40'转动在展开状态和折叠状态之间切换。具体地，第一壳体40固设于第一转动机构20的连接件23上时，当第一壳体40受到用户施加的外力或者其他机构给予的外力时，第一壳体40进行转动进而带动第一转动机构20的连接件23转动，第一转动机构20的连接件23转动可带动第一转动机构20的第一转动件21、第二转动件22、以及第一从动件71进行转动，同时第一从动件71转动还可带动第一支撑件31相对第一转动机构20的连接件23转动。第二壳体40'固设于第二转动机构20'的连接件23上时，当第二壳体40'受到用户施加的外力或者其他机构给予的外力时，第二壳体40'进行转动进而带动第二转动机构20'的连接件23转动，第二转动机构20'的连接件23转动可带动第二转动机构20'的第一转动件21、第二转动件22、以及第二从动件71'进行转动，同时第二从动件71'转动还可带动第二支撑件31'相对第二转动机构20'的连接件23转动。直至第一支撑件31与第二支撑件31'与支架10弯折成水滴状或者展开成水平状。
本实施方式提供的壳体组件2，通过采用本申请上述实施方式提供的折叠装置1，可使得壳体组件2在长度方向上的尺寸不会发生变化，有利于小型化的发展。并且还可使得第一壳体40与第二壳体40'不会相对第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22进行转动，提高了壳体组件2的稳定性。
请一并参考图30-图33，图30为本申请一实施方式中装饰件与折叠装置的配合示意图。图31为图30所示装饰件与折叠装置的分解示意图。图32为本申请一实施方式中第一转动机构与第二转动机构的第一转动件、第二转动件、及装饰件的分解示意图。图33为本申请另一实施方式中第一转动机构与第二转动机构的第一转动件、第二转动件、及装饰件的分解示意图。本实施方式中，壳体组件2还包括装饰件50，装饰件50包括底壁51、及与底壁51周缘弯折连接的侧壁52，折叠装置1的支架10固设于底壁51。折叠装置1的第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22均包括避让部53，避让部53用于避让侧壁52。或者，侧壁52设有避让空间54，第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22能够设于避让空间54内。
壳体组件2除了包括壳体与折叠装置1外，还可包括装饰件50。装设件主要用于装设折叠装置1，为折叠装置1提供装设基础，并且装饰件50还可保护折叠装置1，防止折叠装置1接触外界而损坏。同时装饰件50可与第一壳体40与第二壳体40'共同构成壳体组件2的外观面，因此可同样对装饰件50的表面进行设计，从而提高壳体组件2的外观性能。本实施方式并不对装饰件50的材质、形状、结构等参数进行限定，只要装饰件50能够实现装设、保护、及外观等作用即可。
装饰件50可包括底壁51，及与底壁51周缘弯折连接的侧壁52，本实施方式可将支架10固设于底壁51上。在一些实施方式中可采用螺钉等方式将支架10螺钉连接至底壁51上行。在其他实施方式中也可采用例如粘接、卡扣连接等方式进行固定。
可选地，壳体组件2可包括两个或两个以上的折叠装置1，多个折叠装置1沿底壁51的长度方向间隔设置于底壁51上。
由于装饰件50侧壁52的存在，导致壳体组件2中的第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22在运动至展平状态时有可能会与侧壁52发生干涉，从而阻碍第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22的转动。因此本实施方式提供了两种解决方式。一种实施方式中可在第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22上设置避让部53，利用该避让部53来避让侧壁52。具体地，可在第一转动机构20与第二转动机构20'的第一转动 件21与第二转动件22靠近底壁51的一侧设置避让部53，并使避让部53朝向远离侧壁52的方向凸起，从而防止侧壁52与第一转动机构20与第二转动机构20'的第一转动件21和第二转动件22发生干涉。
第二种实施方式中，可以在侧壁52上设置两个避让空间54，这样当第一支撑件31与第二支撑件31'完全展平时第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22能够分别设于一个避让空间54内，从而防止侧壁52与第一转动机构20与第二转动机构20'的第一转动件21和第二转动件22发生干涉。具体地，避让空间54可同时贯穿侧壁52背离底壁51的一侧表面、侧壁52靠近支架10的一侧表面、以及侧壁52远离支架10的一侧表面。至于底壁51可不开设避让空间54，使用户从外界无法透过底壁51看到壳体组件2的内部情况，从而更有效地保护壳体组件2。
另外，不管是在第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22上设置避让部53还是在在侧壁52上设置避让空间54，除了具有避让的功能外，还可利用上述的避让设计使第一支撑件31与第二支撑件31'处于完全相互展开的状态时使第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22和侧壁52相接触，利用侧壁52来限位第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22，防止第一转动机构20与第二转动机构20'的第一转动件21与第二转动件22反折从而损坏壳体组件2。
在其他实施方式中，第一从动件71与第二从动件71'上也可设置有避让部53，或者侧壁52上设置避让空间54，利用避让部53或避让空间54来防止第一从动件71与第二从动件71'与侧壁52发生干涉。
请再次参考图21-图25，本实施方式中，第一壳体40与第二壳体40'均包括本体41及设于本体41靠近折叠装置1一侧的凸起部42，第一转动机构20的连接件23固设于第一壳体40的凸起部42上，第二转动机构20'的连接件23固设于第二壳体40'的凸起部42上，当第一支撑件31与第二支撑件31'处于完全相互展开状态时，第一壳体40的凸起部42与第二壳体40'的凸起部42设于装饰件50背离折叠装置1的一侧。
本实施方式提供了一种第一壳体40与第二壳体40'的部分设于折叠装置1的相对两侧的具体结构。第一壳体40与第二壳体40'均包括本体41与凸起部42，其中本体41用于承载屏幕，且本体41内具有用于收容并装设各种各样结构件的空间，例如可在第一壳体40内装设电池、电路板、摄像模组等等。并且由于本实施方式包括第一壳体40与第二壳体40'，第一壳体40与第二壳体40'的本体41内可设有不同的结构件。第一壳体40与第二壳体40'的凸起部42主要用于装设折叠装置1中的第一转动机构20的连接件23，并且凸起部42还可起到保护折叠装置1的作用。在其他实施方式中，凸起部42内也可相应设置一些尺寸较小的结构件例如小板。
本体41与凸起部42可以为一体式结构，也可以为分体式结构。当本体41与凸起部42为一体式结构时，本体41与凸起部42是通过一道工序制备而成，只不过为了便于理解，人为将本体41与凸起部42进行了不同的命名。当本体41与凸起部42为分体式结构时，本体41与凸起部42是分开制备的，然后再通过各种方法例如插接连接在一起。本实施方式仅以本体41与凸起部42为一体式结构进行示意性说明。
本体41具有相背设置的正面410、反面411、以及弯折连接于正面410与反面411之间且靠近折叠装置1的侧面412。其中正面410后续用于支撑屏幕，反面411用于充当壳体组件2的外观面，侧面412则用于设置凸起部42。具体地，凸起部42设于侧面412且靠近反面411的一侧，这样凸起部42与本体41可形成一个台阶结构，即形成一个向上的装设空间413，而第一转动机构20的连接件23与部分第一支撑件31便可设于装设空间413内，且第一转动机构20的连接件23固设于凸起部42靠近正面410的一侧表面上。可选地，凸起部42背离正面410的一侧表面与本体41的反面411齐平，提高第一壳体40与第二壳体40'表面的平整度。
当第一支撑件31与第二支撑件31'处于完全相互展开时，即壳体组件2处于展开状态时，两个凸起部42可设于装饰件50背离折叠装置1的一侧，这样便可使整个折叠装置1设于第一壳体40与第二壳体40'的装设空间413内，并利用两个凸起部42来遮挡装饰件50与折叠装置1，使壳体组件2从外观上 更加简洁。可选地，当第一支撑件31与第二支撑件31'处于完全相互展开时，第一壳体40的凸起部42与第二壳体40'的凸起部42可相互抵接，或者第一壳体40的凸起部42与第二壳体40'的凸起部42可具有一定的间隙。
当第一支撑件31与第二支撑件31'处于完全相互折叠时，即壳体组件2处于折叠状态时，两个凸起部42连同各自连接的本体41设于折叠装置1与装饰件50的相对两侧，且第一壳体40与第二壳体40'与装饰件50的下表面共同构成壳体组件2的外观面。可选地，装饰件50的侧壁52的形状为弧形，从而在第一壳体40的转动过程中避让第一壳体40与第二壳体40'，防止第一壳体40与第二壳体40'与侧壁52发生干涉。
本申请还提供了一种利用上述壳体组件2装配形成的电子设备3。请一并参考图34-图42，图34为本申请一实施方式中电子设备处于展开状态时的立体结构示意图。图35为图34所示的电子设备部分结构爆炸图。图36-图38分别为图34所示的电子设备不同部位的截面示意图。图39为本申请一实施方式中电子设备处于折叠状态时的立体结构示意图。图40-图42分别为图39所示的电子设备不同部位的截面示意图。
本实施方式提供了一种电子设备3，电子设备3包括屏幕60及如本申请上述实施方式提供的壳体组件2，屏幕60支撑于所述折叠装置1的第一支撑件31及第二支撑件31'，当所述电子设备3折叠时，所述第一壳体40与所述第二壳体40'相互折叠，所述第一支撑件31及第二支撑件31'相互折叠，所述屏幕60的两端相互折叠；当所述电子设备3展开时，所述第一壳体40与所述第二壳体40'相互展开，第一支撑件31及第二支撑件31'相互展开，所述屏幕60的两端相互展开。
本实施方式提供的电子设备3包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、个人计算机(Personal Computer，PC)、个人数字助理(Personal Digital Assistant，PDA)、便携式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等移动终端，以及诸如数字TV、台式计算机等固定终端。本实施方式对电子设备3的种类并不进行限定。本实施方式仅以电子设备3为手机进行示意性说明。
电子设备3包括屏幕60及壳体组件2，屏幕60是一种具有一定柔性的结构件，相较于刚性件屏幕60可进行一定的弯折。例如屏幕60包括但不限于柔性显示屏、柔性触摸屏、柔性触摸显示屏等各种具备相应功能的柔性部件，或者为固定贴合有柔性支撑板的柔性部件，如贴合有柔性钢板的柔性显示屏、柔性触摸屏等。屏幕60设于壳体组件2的一侧，且可随着壳体组件2折弯或者展平。具体地，屏幕60具有弯折区61、以及设于弯折区61相对两侧的非弯折区62。其中弯折区61对应贴合折叠装置1设置，非弯折区62对应固设于壳体40的正面410。弯折区61的屏幕60由于对应贴合于折叠装置1上，折叠装置1在运动时其形状会发生改变，因此能带动弯折区61的屏幕60也同样弯折，从而随电子设备3的运动折弯或展平。非弯折区62由于固设于壳体40上，壳体40只会发生相对的转动运动，壳体40本身并不会发生形状的改变，因此即使壳体40转动，壳体40上的屏幕60也不进行弯折。
电子设备3同样具有展开状态与折叠状态，其中展开状态指的是第一支撑件31与第二支撑件31'处于完全相互展开时的状态，也可以理解为屏幕60展平时的状态，或者说屏幕60的显示面齐平时的状态。折叠状态指的是第一支撑件31与第二支撑件31'处于完全相互折叠时的状态，也可以理解为屏幕60弯折且两半屏幕60相互靠近时的状态，或者说屏幕60的显示面弯折时的状态。
当所述电子设备3折叠时，所述第一壳体40与所述第二壳体40'相互折叠，所述第一支撑件31及第二支撑件31'相互折叠，所述屏幕60的两端相互折叠；当所述电子设备3展开时，所述第一壳体40与所述第二壳体40'相互展开，第一支撑件31及第二支撑件31'相互展开，所述屏幕60的两端相互展开。换句话说，当电子设备3折叠时，两个壳体先进行折叠，随后带动两个支撑件相互折叠，最终使屏幕60的两端相互折叠。当电子设备3展开时，两个壳体先展开，随后带动两个支撑件相互展开，最终使屏幕60的两端相互展开。对于上述电子设备3在折叠与展开时具有多种主动从动关系，本实施方式将详细介绍其中一种具体的可实现方式。
当电子设备3欲从展开状态至折叠状态时，即电子设备3需要进行弯折时，此时用于只需朝电子设备3的中心推动或拉拽壳体40，便可让壳体40进行转动，壳体40转动的过程中便可带动固设于壳体40上的连接件23以及屏幕60进行转动，进而带动与第一转动机构20的连接件23连接的第一转动机构20的第一转动件21、第二转动件22、第一支撑件31及第一从动件71相对支架10进行转动。由于第一从动件71与支架10的第三转动轴线C33与第一转动件21与支架10的第一转动轴线C11、以及第二转动件22与支架10的第二转动轴线C22具有一定的位置关系，因此可使得第一从动件71与第一支撑件31的第三转动轴心线C3相较于第一支撑件31与连接件23之间的第四转动轴心线C4之间进行相应的运动，从而驱动第一支撑件31靠近支架10的一端相对连接件23朝向靠近连接件23的方向转动，同样使第一支撑件31上屏幕60朝靠近连接件23的方向弯曲。至于第二支撑件31'可做同样的理解。最终当壳体40转动90°后，第一壳体40与第二壳体40'上的非弯折区62的屏幕60相互抵接，从而使得电子设备3在第一壳体40与第二壳体40'处没有间隙，可实现完全抵接，不仅可有效保护屏幕60还可降低电子设备3的厚度。折叠装置1上的弯折区61的屏幕60则形成上小下大的水滴形状。
当电子设备3想要重新从折叠状态回归到展开状态时，用户只需要向外拽壳体40，使壳体40进行转动，壳体40转动的过程中便可带动固设于壳体40上的连接件23以及屏幕60进行转动，进而带动与第一转动机构20的连接件23连接的第一转动机构20的第一转动件21、第二转动件22、第一支撑件31、及第一从动件71相对支架10进行转动。同样由于第一从动件71与支架10的第三转动轴线C33与第一转动件21与支架10的第一转动轴线C11、以及第二转动件22与支架10的第二转动轴线C22具有一定的位置关系，因此可使得第一从动件71与第一支撑件31的第三转动轴心线C3相较于第一支撑件31与连接件23之间的第四转动轴心线C4之间进行相应的反向运动，从而驱动第一支撑件31靠近支架10的一端相对连接件23朝向远离连接件23的方向转动，使第一支撑件31重新回到展平的位置。进而带动第一支撑件31上的屏幕60朝向远离连接件23的方向反向弯曲，使屏幕60具有回复展平的趋势。至于第二支撑件31'可做同样的理解。最终当壳体40反向转动90°后，第一支撑件31与第二支撑件31'重新恢复到完全展开的状态，屏幕60也重新恢复到表面齐平的形状。
综上，本实施方式提供的电子设备3，通过采用本申请上述实施方式提供的壳体组件2，可使得电子设备3在长度方向上的尺寸不会发生变化，有利于小型化的发展。并且还可使得壳体40不会相对第一转动件21与第二转动件22进行转动，提高了电子设备3的稳定性。
对于电子设备3来说，也可以从另一角度进行理解。例如本申请一种可折叠的电子设备3，包括屏幕60及折叠装置1，所述折叠装置1包括支架10，并排设置的第一转动机构与20第二转动机构20'，所述第一转动机构20与所述第二转动机构20'均包括第一转动件21、第二转动件22、及连接件23；所述第一转动件21与所述第二转动件22的一端均转动连接于所述支架10，所述第一转动件21与所述第二转动件22的另一端均转动连接于所述连接件23，且所述第一转动件21与所述连接件23之间的第一转动轴心线C1平行不重合于所述第二转动件22与所述连接件23之间的第二转动轴心线C2。支撑机构30，用于支撑屏幕60，支撑机构30包括设于所述支架10相对两侧的第一支撑件31与第二支撑件31'，所述第一支撑件31转动连接于所述第一转动机构10的连接件23，所述第二支撑件31'转动连接于所述第二转动机构20'的连接件23。从动机构70，包括设于所述支架10相对两侧的第一从动件71与第二从动件'，所述第一从动件71的一端转动连接于所述支架10，另一端转动连接于所述第一支撑件31，所述第二从动件71'的一端转动连接于所述支架10，另一端转动连接于所述第二支撑件31'。
当所述电子设备3折叠时，所述第一从动件71、所述第二从动件71'、及所述第一转动机构20与所述第二转动机构20'的所述第一转动件21、所述第二转动件22转动，所述第一支撑件31及所述第二支撑件31'相互折叠，所述屏幕60的两端相互折叠；当所述电子设备3展开时，所述第一从动件71、所述第二从动件71'、及所述第一转动机构20与所述第二转动机构20'的所述第一转动件21、所述第二转动件22转动，所述第一支撑件31及所述第二支撑件31'相互展开，所述屏幕60的两端相互展开。
本实施方式中，电子设备3具有第一支撑件31与第二支撑件31'处于完全相互展开时的展开状态， 及第一支撑件31与第二支撑件31'处于完全相互折叠时的折叠状态，支架10具有用于靠近屏幕的顶面101。其中，当电子设备3处于展开状态时在平行于顶面101的方向上，第二支撑件31'与第二从动件71'之间的第三转动轴心线C3、及第二支撑件31'与第二转动机构20'的连接件23之间的第四转动轴心线C4之间的距离为第一距离。当电子设备3处于折叠状态时在垂直于顶面101的方向上，第三转动轴心线C3及第四转动轴心线C4之间的距离为第二距离，第二距离小于第一距离。
