一些可能的实现方式中，电子设备处于打开状态时，第一支撑板搭接第一摆臂，第二支撑板搭接第二摆臂。由于第一摆臂能够为第一支撑板提供刚性支撑，第二摆臂能够为第二支 撑板提供刚性支撑，因此能够通过搭接设计，提高第一支撑板和第二支撑板的局部刚度，减小第一支撑板和第二支撑板的按压虚位，以提升屏幕的可靠性。
一些可能的实现方式中，第一支撑板具有搭接第一摆臂的第二搭接面，第一支撑板的第二搭接面与第一摆臂之间形成斜面配合，不仅有利于提高搭接面积，使得第一摆臂对第一支撑板的支撑更为稳定，还能够使第一支撑板与第一摆臂的相对运动不易干涉、更为顺畅。第二支撑板具有搭接第二摆臂的第二搭接面，第二支撑板的第二搭接面与第二摆臂之间形成斜面配合，不仅有利于提高搭接面积，使得第二摆臂对第二支撑板的支撑更为稳定，还能够使第二支撑板与第二摆臂的相对运动不易干涉、更为顺畅。
一些可能的实现方式中，电子设备处于闭合状态时，第一支撑板搭接第一固定架、第一摆臂或第一连接臂，第二支撑板搭接第二固定架、第二摆臂或第二连接臂。此时，连接组件的摆臂、固定架及连接臂均能够为支撑板提供刚性支撑，使得第一支撑板和第二支撑板的相对位置稳定，为屏幕的折弯部提供稳定的支撑环境。第一支撑板和第二支撑板能够与主轴配合、形成稳定性更好的收容空间，更易维持屏幕的折弯部的水滴状，有利于提高屏幕的可靠性。

折叠组件具有主轴、位于主轴两侧的两个支撑板及多个运动件，电子设备处于打开状态时，主轴、两个支撑板及多个运动件的端部拼接，从而提供一个平整、连续的、破孔小或无破孔的支撑环境，使得折叠组件能够可靠支撑屏幕的折弯部，降低屏幕的折弯部在按压或撞击下发生凹陷的风险，提高屏幕的可靠性。
此外，电子设备处于打开状态时，主轴和/或多个运动件还能够为支撑板提供结构支撑，使得支撑板按压虚位小、变形小，进一步提高了屏幕的可靠性。
其中，电子设备可以是手机、平板电脑、笔记本电脑、可穿戴设备等可折叠的电子产品。本申请实施例以电子设备是手机为例进行说明。
请结合参阅图1、图2和图3，图1是本申请实施例提供的一种电子设备200处于打开状态时的结构示意图，图2是图1所示电子设备200处于中间状态时的结构示意图，图3是图1所示电子设备200处于闭合状态时的结构示意图。一些实施例中，电子设备200为可折叠的设备，具有打开状态和闭合状态。示例性的，电子设备200包括壳体装置1和屏幕2，屏幕2安装于壳体装置1。如图1所示，壳体装置1可以展开至打开状态；如图3所示，壳体装置1还可以折叠至闭合状态；如图2所示，壳体装置1还可以展开或折叠至中间状态，中间状态可以为打开状态与闭合状态之间的任意状态。屏幕2为可弯折结构，屏幕2随壳体装置1运动，壳体装置1可以带动屏幕2展开或折叠，以使电子设备200能够展开或折叠至打开状态、闭合状态或中间状态。其中，电子设备200处于闭合状态时，屏幕2位于壳体装置1内侧，电子设备200为屏幕内折式设备。
在本实施例中，当电子设备200处于打开状态时，屏幕2展平，屏幕2能够进行全屏显示，使得电子设备200具有较大的显示面积，以提高用户的观看体验和操作体验。当电子设备200处于闭合状态时，电子设备200的平面尺寸较小，便于用户携带和收纳。
一些实施例中，电子设备200还可以包括多个部件(图中未示出)，多个部件安装于壳体装置1内部。多个部件例如可以包括处理器、内部存储器、外部存储器接口、通用串行总线(universal serial bus，USB)接口、充电管理模块、电源管理模块、电池、天线、通信模块、摄像头、音频模块、扬声器、受话器、麦克风、耳机接口、传感器模块、按键、马达、指示器以及用户标识模块(subscriber identification module，SIM)卡接口等。其中，电子设备200可以具有比上文描述的更多的或者更少的部件，可以组合两个或多个的部件，或者可以具有不同的部件配置。各种部件可以在包括一个或多个信号处理和/或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。
可以理解的是，用户手持电子设备200时，电子设备200的听筒模组所在位置可以定义为电子设备200的上边，电子设备200的麦克风模组所在位置可以定义为电子设备200的下边，电子设备200的被用户的左右手握持的两侧可以定义为电子设备200的左右两边。在一些实施例中，电子设备200能够实现左右对折。在其他一些实施例中，电子设备200能够实 现上下对折。
请结合参阅图1至图5，图4是图1所示电子设备200的部分分解结构示意图，图5是图4所示的壳体装置1的部分分解示意图。
一些实施例中，壳体装置1包括第一壳体11、第二壳体13及折叠组件12。其中，折叠组件12可以连接在第一壳体11与第二壳体13之间。折叠组件12可以发生运动，以使第一壳体11与第二壳体13能够相对展开至打开状态或相对折叠至闭合状态，还能够相对展开或相对折叠至中间状态。应理解，电子设备200处于打开状态时，屏幕2、壳体装置1及壳体装置1的各部件对应地处于打开状态；电子设备200处于闭合状态时，屏幕2、壳体装置1及壳体装置1的各部件对应地处于闭合状态；电子设备200处于中间状态时，屏幕2、壳体装置1及壳体装置1的各部件对应地处于中间状态。
其中，如图1所示，电子设备200处于打开状态时，第一壳体11与第二壳体13之间的夹角可以大致呈180°，第一壳体11与第二壳体13展平，屏幕2呈现展平形态，此时第一壳体11可以与第二壳体13拼接，第一壳体11与第二壳体13拼接包括了两者相互抵持的情况，也可以包括两者之间有小缝隙的情况。在本实施例中，通过第一壳体11与第二壳体13的拼接，能够实现对壳体装置1展开动作的止位，以防止壳体装置1在展开时过折，从而降低屏幕2的受力，提高屏幕2和电子设备200的可靠性。
在其他一些实施例中，电子设备200处于打开状态时，第一壳体11与第二壳体13之间的角度也可以相对180°存在少许偏差，例如165°、177°或者185°等，这种情况也认为第一壳体11与第二壳体13展平。其中，第一壳体11与第二壳体13的夹角，定义为第一壳体11的上侧与第二壳体13的上侧之间的夹角。
如图3所示，电子设备200处于闭合状态时，第一壳体11与第二壳体13之间的夹角可以大致呈0°，第一壳体11与第二壳体13折叠至合拢状态，屏幕2呈现折叠形态。示例性的，第一壳体11与第二壳体13呈合拢状态时，两者可以相互接触，以实现定位。在其他一些实施例中，第一壳体11与第二壳体13呈合拢状态时，两者也可以相互靠近，且两者之间存在微小缝隙，本申请对此不作严格限定。当第一壳体11与第二壳体13存在微小缝隙时，电子设备200外部的一些异物(例如钉子、曲别针、玻璃渣等)也不会通过该缝隙进入第一壳体11与第二壳体13之间，以避免异物损伤屏幕2，从而提高了电子设备200的可靠性。
可以理解的，第一壳体11和第二壳体13为壳体件，用于安装和固定电子设备200的其他部件，具有多样化的结构，本申请实施例只简要地对第一壳体11和第二壳体13的部分结构做示例性说明，附图中也进行简化示意，本申请实施例不对第一壳体11和第二壳体13具体结构作严格限定。
一些实施例中，请结合参阅图1和图4，屏幕2包括依次排列的第一非折弯部21、折弯部22以及第二非折弯部23。第一非折弯部21固定连接第一壳体11，第二非折弯部23固定连接第二壳体13，折弯部22对应折叠组件12设置，在第一壳体11与第二壳体13相对折叠或相对展开的过程中，折弯部22发生形变。在第一壳体11与第二壳体13相对折叠或相对展开的过程中，第一壳体11带动第一非折弯部21活动，第二壳体13带动第二非折弯部23活动，第一非折弯部21与第二非折弯部23相对折叠或展开。
一些实施例中，请参阅图4，第一壳体11包括用于承载屏幕2的支撑面111，第二壳体13包括用于承载屏幕2的支撑面131。示例性的，屏幕2的第一非折弯部21可以固定连接第一壳体11的支撑面111。例如，第一非折弯部21可以通过胶层粘接于第一壳体11的支撑面111。第二非折弯部23固定连接第二壳体13的支撑面131。例如，第二非折弯部23可以通 过胶层粘接于第二壳体13的支撑面131。
在本实施例中，由于第一非折弯部21固定连接第一壳体11、第二非折弯部23固定连接第二壳体13，因此第一壳体11与第二壳体13相对折叠或展开时，能够准确地控制第一非折弯部21与第二非折弯部23之间的相对折叠和展开的动作，使得屏幕2的变形过程和运动形态可控，可靠性较高。
如图1所示，第一壳体11与第二壳体13相对展开至打开状态时，屏幕2的第一非折弯部21、折弯部22及第二非折弯部23相对展平，屏幕2处于展平形态。如图2所示，第一壳体11与第二壳体13处于中间状态时，屏幕2的第一非折弯部21与第二非折弯部23之间形成夹角，折弯部22发生部分弯折，屏幕2处于弯折形态。如图3所示，第一壳体11与第二壳体13相对折叠至闭合状态时，屏幕2位于折叠装置的内侧，处于折叠形态。其中，屏幕2的折叠形态的相关细节可以参阅后文描述。
其中，屏幕2可以包括显示模组和支撑板，显示模组为柔性显示屏，支撑板位于显示模组的下方，用于支撑显示模组、增加显示模组的结构刚度。其中，支撑板位于折弯部22的部分的刚度小于位于第一非折弯部21和第二非折弯部23的部分的刚度，也即，支撑板位于折弯部22的部分的刚度较小，支撑板位于第一非折弯部21和第二非折弯部23的部分的刚度较大，使得屏幕2既可以兼顾结构刚度、以具有较高的平整度，同时屏幕2的折弯部22也可以顺利弯折。
可以理解的，第一壳体11的支撑面111和第二壳体13的支撑面131可以是连续的、完整的表面，也可以是包括有多个凹陷区域或镂空区域的表面，本申请实施例对此不作严格限定。
其中，显示模组可以集成有显示功能和触摸感测功能。屏幕2的显示功能用于显示图像、视频等，屏幕2的触摸感测功能用于感测用户的触摸动作，以实现人机交互。其中，显示模组可以采用液晶显示屏(liquid crystal display，LCD)、有机发光二极管(organic light-emitting diode，OLED)显示屏、有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode，AMOLED)显示屏、柔性发光二极管(flex light-emitting diode，FLED)显示屏、MiniLED显示屏、MicroLED显示屏、Micro-OLED显示屏、量子点发光二极管(quantum dot light emitting diodes，QLED)显示屏等。

请结合参阅图7和图8，图8是图6所示主轴31的部分结构示意图。
一些实施例中，主支撑板41可以设有多组避让空间，多组避让空间分别排布于主支撑板41的顶部、中部及底部，与顶部连接组件32、中部连接组件33及底部连接组件34一一对应，用于在折叠组件12的运动过程中，避让多个连接组件(32、33、34)的运动件，以使折叠组 件12的运动过程顺畅，可靠性高。

示例性的，第一连接臂323的第一端3231的第一弧形臂3233安装于主轴31的第一弧形空间41b，以通过虚拟轴的连接方式，使第一连接臂323的第一端3231转动连接主轴31。转轴3281穿过第一连接臂323的第二端3232的转轴孔3234，且穿过第一固定架321的第一转轴孔3211，以插接第一连接臂323的第二端3232和第一固定架321，使得第一连接臂323的第二端3232通过实体轴的连接方式转动连接第一固定架321。
其中，第二连接臂324的第一端3241的第二弧形臂3243安装于主轴31的第二弧形空间41c，以通过虚拟轴的连接方式，使第二连接臂324的第一端3241转动连接主轴31。转轴3282穿过第二连接臂324的第二端3242的转轴孔3244、且穿过第二固定架322的第二转轴孔3221，以插接第二连接臂324的第二端3242和第二固定架322，使得第二连接臂324的第二端3242通过实体轴的连接方式、转动连接第二固定架322。
示例性的，如图25所示，折叠组件12处于打开状态时，第一弧形臂3233的端部至少部分位于第一避让孔412，例如，第一弧形臂3233的第一凸块3233a至少部分位于主支撑板41的第一避让孔412中。此时，第一避让孔412的设计使得第一弧形臂3233能够具有较大的弧度，第一弧形臂3233与主支撑板41的第一弧形空间41b的配合弧度(也即第一弧形臂3233伸入第一弧形空间41b的弧度)更大，两者的相对运动更为平稳。此外，还能够降低第一弧形臂3233脱离主支撑板41的风险，使得两者的连接关系更为可靠。
折叠组件12处于打开状态时，第二弧形臂3243的端部至少部分位于第二避让孔413，例如，第二弧形臂3243的第二凸块3243a至少部分位于主支撑板41的第二避让孔413中。此时，第二避让孔413的设计使得第二弧形臂3243能够具有较大的弧度，第二弧形臂3243与主支撑板41的第二弧形空间41c的配合弧度更大，两者的相对运动更为平稳。此外，还能够降低第二弧形臂3243脱离主支撑板41的风险，使得两者的连接关系更为可靠。
在本实施例中，折叠组件12处于打开状态时，由于第一凸块3233a至少部分位于第一避让孔412中，可以填补第一避让孔412，第二凸块3243a至少部分位于第二避让孔413中，可以填补第二避让孔413，使得主支撑板41能够为屏幕2的折弯部22提供一个较为完整的支撑环境，以提高屏幕2的可靠性。
其中，折叠组件12处于打开状态时，第一凸块3233a可以占据第一避让孔412的大部分空间。一些实施例中，第一凸块3233a的端面可以与主支撑板41的支撑面411齐平、以实现拼接，从而提供更为完整且平整的支撑环境。在另一些实施例中，第一凸块3233a的端面也可以相对主支撑板41的支撑面411稍微下凹，以兼顾第一弧形臂3233的连接需求和屏幕2的支撑需求。此时，由于第一避让孔412的开口面积较小，且第一凸块3233a的端面相对主支撑板41的支撑面411的下凹程度较浅，因此屏幕2的折弯部22对应于第一避让孔412的 区域受到按压或冲撞时，发生明显凹陷或损坏的风险较小，屏幕2的可靠性较高。
折叠组件12处于打开状态时，第二凸块3243a可以占据第二避让孔413的大部分空间。一些实施例中，第二凸块3243a的端面可以与主支撑板41的支撑面411齐平、以实现拼接，从而提供更为完整且平整的支撑环境。在另一些实施例中，第二凸块3243a的端面也可以相对主支撑板41的支撑面411稍微下凹，以兼顾第二弧形臂3243的连接需求和屏幕2的支撑需求。此时，由于第二避让孔413的开口面积较小，且第二凸块3243a的端面相对主支撑板41的支撑面411的下凹程度较浅，因此屏幕2的折弯部22对应于第二避让孔413的区域受到按压或冲撞时，发生明显凹陷或损坏的风险较小，屏幕2的可靠性较高。
在其他一些实施例中，也可以通过结构设计或尺寸设计等，使得第一弧形臂3233及第二弧形臂3243与主支撑板41的配合弧度足够，此时，主支撑板41上可以不设置第一避让孔412和第二避让孔413，主支撑板41的完整度较高，能够更好地支撑屏幕2的折弯部22。
可以理解的是，在其他一些实施例中，第一连接臂323的第一端3231可以通过实体轴的连接方式转动连接主轴31；和/或，第二连接臂324的第一端3241，可以通过实体轴的连接方式转动连接主轴31，本申请对此不作严格限定。在其他一些实施例中，第一连接臂323的第二端3232可以通过虚拟轴的连接方式转动连接第一固定架321；和/或，第二连接臂324的第二端3242可以通过虚拟轴的连接方式转动连接第二固定架322，本申请对此不作严格限定。
请参阅图29，图29是图24所示结构沿E-E剖开的截面结构示意图。
一些实施例中，第一连接臂323的第一配合块3235a可以安装于第一固定架321的第一配合槽3213，以与第一固定架321的第一配合槽3213配合。其中，第一配合块3235a的配合面3235b接触第一配合槽3213的配合壁面3213a。第二连接臂324的第二配合块3245a可以安装于第二固定架322的第二配合槽3223，以与第二固定架322的第二配合槽3223配合。其中，第二配合块3245a的配合面3245b接触第二配合槽3223的配合壁面3223a。
在本实施例中，上述配合面与配合壁面的接触结构增加了配合块与固定架的接触面积，从而增加了连接臂与固定架的连接稳定性，提高了折叠组件12的可靠性。
示例性的，第一配合块3235a的配合面3235b和/或第一配合槽3213的配合壁面3213a可以为弧面，第一配合块3235a的配合面3235b与第一配合槽3213的配合壁面3213a形成弧面搭接。第二配合块3245a的配合面3245b和/或第二配合槽3223的配合壁面3223a可以为弧面，第二配合块3245a的配合面3245b与第二配合槽3223的配合壁面3223a形成弧面搭接。
在本实施例中，上述弧面搭接结构增加了连接臂与固定架在折叠组件12运动过程中的连接稳定性，使得连接臂与固定架的相对运动更为平稳，提高了折叠组件12的可靠性。
请结合参阅图30和图31，图30是图24所示结构沿F-F处剖开的截面结构示意图，图31是图30所示结构处于闭合状态时的结构示意图。
一些实施例中，第一摆臂325的转动端3251转动连接主轴31，第一摆臂325的滑动端3252滑动连接第一固定架321；第二摆臂326的转动端3261转动连接主轴31，第二摆臂326的滑动端3262滑动连接第二固定架322。示例性的，第一摆臂325的滑动端3252可滑动地安装于第一固定架321的第一滑动槽3214，以滑动连接第一固定架321。第一摆臂325的转动端3251安装于主轴31，通过第一转接轴3277转动连接主轴31。第二摆臂326的滑动端3262可滑动地安装于第二固定架322的第二滑动槽3224，以滑动连接第二固定架322。第二摆臂326的转动端3261安装于主轴31，通过第二转接轴3278转动连接主轴31。
在本申请中，顶部连接组件32的第一连接臂323的两端分别转动连接主轴31和第一固 定架321，形成了连杆结构，第一摆臂325的转动端3251转动连接主轴31、滑动端滑动连接第一固定架321，形成了连杆滑块结构；第二连接臂324的两端分别转动连接主轴31和第二固定架322，形成了连杆结构，第二摆臂326的转动端3261转动连接主轴31、滑动端滑动连接第二固定架322，形成了连杆滑块结构。
第一固定架321用于连接第一壳体11，第二固定架322用于连接第二壳体13，因此折叠组件12的顶部连接组件32通过连杆结构和连杆滑块结构，实现第一壳体11及第二壳体13与主轴31之间的连接，组成部分数量少，配合关系及配合位置简单，组成部件易制作和组装，有利于实现量产，以降低壳体装置1的成本。并且，由于主轴31通过第一连接臂323和第一摆臂325联动第一固定架321、且通过第二连接臂324和第二摆臂326联动第二固定架322，因此折叠组件12的运动轨迹准确，折叠组件12具有较佳的机构抗拉能力和机构抗挤压能力。
其中，如图30所示，在打开状态中，第一摆臂325的转动端3251转入主轴31，第二摆臂326的转动端3261转入主轴31，第一摆臂325的滑动端3252滑入第一固定架321，第二摆臂326的滑动端3262滑入第二固定架322，第一固定架321及第二固定架322与主轴31之间的距离较小。
如图31所示，在闭合状态中，第一摆臂325的转动端3251部分转出主轴31，第二摆臂326的转动端3261部分转出主轴31，第一摆臂325的滑动端3252部分滑出第一固定架321，第二摆臂326的滑动端3262部分滑出第二固定架322，第一固定架321及第二固定架322与主轴31之间的距离较大。
故而，折叠组件12能够在打开状态中，通过第一固定架321和第二固定架322分别拉近第一壳体11和第二壳体13，使得第一壳体11和第二壳体13靠近主轴31；在闭合状态中，通过第一固定架321和第二固定架322分别推开第一壳体11和第二壳体13，使得第一壳体11和第二壳体13远离主轴31，使得折叠组件12的结构能够更好地适应屏幕2的变形结构，以降低拉扯或挤压屏幕2的风险，提高屏幕2和电子设备200的可靠性。
此外，如图30和图31所示，由于阻尼组件327连接在第一摆臂325与第二摆臂326之间，阻尼组件327能够在第一摆臂325和第二摆臂326运动时提供阻尼力和推动力，第一摆臂325能够通过第一固定架321连接第一壳体11，第一摆臂325随第一壳体11运动，第二摆臂326能够通过第二固定架322连接第二壳体13，第二摆臂326随第二壳体13运动，因此在第一壳体11与第二壳体13相对展开或折叠的过程中，阻尼组件327能够提供阻尼力，使得用户在展开或折叠电子设备200时，能够感应到阻力和推力，从而获得较佳的手感开合体验，提高了电子设备200的机构操作感体验。此外，阻尼组件327还可以使第一摆臂325和第二摆臂326停留在某些位置，从而使第一壳体11与第二壳体13能够停留在某些位置，从而可以更好地保持打开状态或闭合状态，以提高用户的使用体验。
此外，第一摆臂325的转动端3251通过多个同步齿轮3273啮合第二摆臂326的转动端3261，使得第一摆臂325的转动端3251的转动角度与第二摆臂326的转动端3261的转动角度，大小相同且方向相反，使得第一摆臂325与第二摆臂326相对主轴31的转动动作保持同步，也即同步相互靠近或相互远离，第一壳体11与第二壳体13相对主轴31的转动动作保持同步，提高了用户的机构操作体验。
可以理解的是，同步齿轮3273的数量、尺寸等可以依据产品具体形态、尺寸等机型设计，本申请对此不做严格限定。其中，同步齿轮3273数量越多、同步齿轮3273的尺寸越小，能够释放更多的空间，同步齿轮3273的数量越少，同步齿轮3273的尺寸越大，同步齿轮3273的传动累积误差更小，有利于提高运动准确性。
可以理解的是，本申请阻尼组件327可以有多种实现结构。例如，在其他一些实施例中，阻尼组件327可以通过对同步齿轮3273的位置限定，间接限定第一摆臂325的位置和第二摆臂326的位置。例如，第一卡位件3271和第二卡位件3272与同步齿轮3273之间形成卡接结构，第一摆臂325的转动端3251与第二摆臂326的转动端3261与第一卡位件3271及第二卡位件3272之间无卡接结构。在其他一些实施例中，阻尼组件327也可以不设置第二卡位件3272，通过第一卡位件3271与同步齿轮3273、第一摆臂325及第二摆臂326之间的卡接结构，使得第一摆臂325和第二摆臂326能够在某些位置停留。在其他一些实施例中，阻尼组件327也可以不设置固定板，弹性件3276的两端可以分别抵持第一卡位件3271和第一安装空间的壁面，弹性件3276被压缩在第一卡位件3271与主轴31之间。在其他一些实施例中，阻尼组件327也可以不设置同步齿轮3273和第三转接轴3279，第一摆臂325的转动端3251直接与第二摆臂326的转动端3261啮合。以上实施例为阻尼组件327的示例性结构，阻尼组件327也可以有其他实现结构，本申请对此不做严格限定。
在其他一些实施例中，第一摆臂325的转动端3251与第二摆臂326的转动端3261之间也可以不设置连接两者的阻尼组件327，第一摆臂325的转动端3251可以通过转轴转动连接主轴31，该转轴可以为第一摆臂325的转动端3251的一部分，也可以为独立结构件且插接第一摆臂325的转动端3251；第二摆臂326的转动端3261也可以通过转轴转动连接主轴31，该转轴可以为第二摆臂326的转动端3261的一部分，也可以为独立结构件且插接第二摆臂326的转动端3261。
请再次参阅图12、图20、图22以及图30，一些实施例中，折叠组件12可以在第一固定架321中设置阻尼结构，用于对第一摆臂325的滑动端3252施加阻尼力，在第二固定架322中设置阻尼结构，用于对第二摆臂326的滑动端3262施加阻尼力。示例性的，第一止位件3291安装于第一安装槽3215，第二止位件3292安装于第二安装槽。折叠组件12处于打开状态时，第一止位件3291能够抵持第一摆臂325的滑动端3252，第二止位件3292抵持第二摆臂326的滑动端3262，通过第一止位件3291对第一摆臂325的限位和第二止位件3292对第二摆臂326的限位，使得壳体装置1在没有受到较大外力时，保持打开状态，以提高用户的使用体验。此外，第一止位件3291和第二止位件3292还能够在电子设备200展开以进入打开状态的过程中、折叠以解除打开状态的过程中，提供限位阻力，使得用户能够体验到较佳的机构操作感。
一些实施例中，如图30和图31所示，在折叠组件12的运动过程中，第一摆臂325相对主轴31转动，主支撑板41的第一避让缺口414用于避让第一摆臂325，使得第一摆臂325与主支撑板41之间不发生干涉，以确保机构运动的顺畅和可靠性。第二摆臂326相对主轴31转动，主支撑板41的第二避让缺口415用于避让第二摆臂326，使得第二摆臂326与主支撑板41之间不发生干涉，以确保机构运动的顺畅和可靠性。

在本实施例中，折叠组件12处于打开状态时，由于第一拼接块3251e至少部分位于第一避让缺口414中，可以填补第一避让缺口414，第二拼接块3261e至少部分位于第二避让缺口415中，可以填补第二避让缺口415，主支撑板41、第一拼接块3251e及第二拼接块3261e 能够用于共同支撑屏幕2的折弯部22，从而主支撑板41为屏幕2的折弯部22提供一个较为完整的支撑环境，以提高屏幕2的可靠性。
示例性的，折叠组件12处于打开状态时，第一拼接块3251e可以占据第一避让缺口414的大部分空间。一些实施例中，第一拼接块3251e的端面可以与主支撑板41的支撑面411齐平、以实现拼接，从而提供更为完整且平整的支撑环境。在另一些实施例中，第一拼接块3251e的端面也可以相对主支撑板41的支撑面411稍微下凹，以兼顾第一连接臂323的连接需求和屏幕2的支撑需求。此时，通过控制第一拼接块3251e的端面相对主支撑板41的支撑面411的下凹程度足够浅，使得屏幕2的折弯部22对应于第一避让缺口414的区域受到按压或冲撞时，发生明显凹陷或损坏的风险较小，屏幕2的可靠性较高。在另一些实施例中，第一拼接块3251e的端面可以与主支撑板41的支撑面411齐平，但两者之间形成一定的间隙，不构成拼接，但这种结构仍然可以为屏幕2提供较好的支撑环境。
第二拼接块3261e可以占据第二避让缺口415的大部分空间。一些实施例中，第二拼接块3261e的端面可以与主支撑板41的支撑面411齐平、以实现拼接，从而提供更为完整且平整的支撑环境。在另一些实施例中，第二拼接块3261e的端面也可以相对主支撑板41的支撑面411稍微下凹，以兼顾第二连接臂324的连接需求和屏幕2的支撑需求。此时，通过控制第二拼接块3261e的端面相对主支撑板41的支撑面411的下凹程度足够浅，使得屏幕2的折弯部22对应于第二避让缺口415的区域受到按压或冲撞时，发生明显凹陷或损坏的风险较小，屏幕2的可靠性较高。在另一些实施例中，第二拼接块3261e的端面可以与主支撑板41的支撑面411齐平，但两者之间形成一定的间隙，不构成拼接，但这种结构仍然可以为屏幕2提供较好的支撑环境。
例如，折叠组件12处于打开状态时，第一拼接块3251e的端面、第二拼接块3261e的端面及主支撑板41的支撑面411齐平，三者位于同一个平面，共同支撑屏幕2的折弯部22，为屏幕2的折弯部22提供一个较为完整且平整的支撑环境，以提高屏幕2的可靠性。
其中，第一拼接块3251e的端面、第二拼接块3261e的端面及主支撑板的支撑面可以拼接，以提高支撑环境的完整性。在其他一些实施例中，第一拼接块3251e的端面、第二拼接块3261e的端面及主支撑板的支撑面中的至少两者之间也可以形成一定间隙、不构成拼接，本申请实施例对此不作严格限定。
此外，折叠组件12处于闭合状态时，第一拼接块3251e和第二拼接块3261e还可以转入主轴31的活动空间41a中，不影响折叠组件12的用于容纳屏幕2的收容空间，提高了折叠组件12的可靠性。此外，折叠组件12处于闭合状态时，第一摆臂325的连接段3253和第二摆臂326的连接段3263能够通过第一避让缺口414和第二避让缺口415靠近彼此，两者之间间距较小，以便折叠组件12整体形成类似水滴状的收容空间。

在本实施例中，第一支撑板35滑动连接第一摆臂325的滑动端3252且转动连接第一固定架321，第一摆臂325的滑动端3252和第一固定架321共同限定第一支撑板35的运动轨迹；第二支撑板36滑动连接第二摆臂326的滑动端3262且转动连接第二固定架322，第二摆臂326的滑动端3262和第二固定架322共同限定第二支撑板36的运动轨迹。因此，第一支撑板35和第二支撑板36能够随连接组件运动，且运动轨迹准确，使得折叠组件12的可靠性更高。
其中，如图34和图36所示，在闭合状态中，折叠组件12的第一支撑板35、主轴31以及第二支撑板36共同围设出类似水滴状的用于容纳屏幕2的收容空间，使得屏幕2能够收容于折叠组件12的内侧，且不易损坏、可靠性高。并且，在折叠组件12的一些位置，折叠组件12的多个连接组件(32、33、34)的运动件，还可以配合第一支撑板35、主轴31及第二支撑板36，以共同围绕出更完整的水滴状的收容空间。如图36所示，第一支撑板35的支撑面351、第一摆臂325的连接段3253的表面、主轴31的主支撑板41的支撑面411、第二摆臂326的连接段3263的表面以及第二支撑板36的支撑面361，共同围绕出水滴状的收容空间。
请再次参阅图35，折叠组件12处于打开状态时，第一摆臂325的第一拼接块3251e至少部分位于主支撑板41的第一避让缺口414，第二摆臂326的第二拼接块3261e至少部分位于主支撑板41的第二避让缺口415。此时，主支撑板41、第一拼接块3251e、第二拼接块3261e、第一支撑板35及第二支撑板36共同支撑屏幕的折弯部，折叠组件12能够为屏幕2的折弯部22提供一个较为完整的支撑环境，使屏幕2的折弯部2受到按压或冲撞时，发生明显凹陷或损坏的风险较小，以提高屏幕2的可靠性。
示例性的，如图35所示，折叠组件12处于打开状态时，主支撑板41的支撑面411、第一拼接块3251e的端面、第一支撑板35的支撑面351、第二拼接块3261e的端面、第二支撑板36的支撑面361共同拼接形成折叠组件12的支撑面。此时，折叠组件12的支撑面无破孔、或者破孔很小，折叠组件12的支撑面较为完整，能够为屏幕2的折弯部22提供良好的支撑环境，以提高屏幕2的可靠性。
其中，第一支撑板35的支撑面351可以是平整的表面，以为屏幕2的折弯部22提供更好的支撑环境。或者，第一支撑板35的支撑面351上也可以设置一个或多个深度很浅的凹槽，这部分凹槽可以用于但不限于用于涂布或安装粘接层，通过粘接层连接屏幕2的折弯部22。 可以理解的是，这部分的凹槽的深度很小，屏幕2对应这部分凹槽的区域在受到外部压力(例如用户的按压力)时不会发生明显凹陷，使得屏幕2的可靠性较高，使用寿命较长。
第二支撑板36的支撑面361可以是平整的表面，以为屏幕2的折弯部22提供更好的支撑环境。或者，第二支撑板36的支撑面361上也可以设置一个或多个深度很浅的凹槽，这部分凹槽可以用于但不限于用于涂布或安装粘接层，通过粘接层连接屏幕2的折弯部22。可以理解的是，这部分的凹槽的深度很小，屏幕2对应这部分凹槽的区域在受到外部压力(例如用户的按压力)时不会发生明显凹陷，使得屏幕2的可靠性较高，使用寿命较长。
示例性的，折叠组件12处于打开状态时，第一支撑板35的第一补充块3514可以至少部分位于第一避让缺口414，使得第一支撑板35的支撑面351、第一拼接块3251e的端面及主支撑板41的支撑面411的拼接效果更好，相邻支撑面之间的缝隙更小。同样的，第二支撑板36的第二补充块3614可以至少部分位于第二避让缺口415，使得第二支撑板36的支撑面361、第二拼接块3261e的端面及主支撑板41的支撑面411的拼接效果更好，相邻支撑面之间的缝隙更小。
当然，在其他一些实施例中，也可以通过结构或尺寸设计，使得第一摆臂325的第一拼接块3251e能够更高程度地填充第一避让缺口414，第二摆臂326的第二拼接块3261e能够更高程度地填充第二避让缺口415，则第一支撑板35可以不设置第一补充块3514，第二支撑板36可以不设置第二补充块3614。本申请实施例不对支撑板、主轴31及运动件的具体拼接结构作严格限定。
在本申请实施例中，在折叠组件12处于打开状态时，第一支撑板35和第二支撑板36可以搭接主轴31及多个连接组件(32、33、34)的部分运动件，使得主轴31及运动件能够为第一支撑板35和第二支撑板36提供刚性支撑，减小第一支撑板35和第二支撑板36的按压虚位，以提升屏幕2的可靠性。以下进行举例说明。
请再次参阅图33，折叠组件12处于打开状态时，第一支撑板35搭接主支撑板41的第一支撑块416，第二支撑板36搭接主支撑板41的第二支撑块417。在本实施例中，折叠组件12处于打开状态时，由于主支撑板41的第一支撑块416能够为第一支撑板35提供刚性支撑，第二支撑块417能够为第二支撑板36提供刚性支撑，因此能够通过搭接设计，提高第一支撑板35和第二支撑板36的局部刚度，减小第一支撑板35和第二支撑板36的按压虚位，以提升屏幕2的可靠性。
示例性的，第一支撑板35具有搭接第一支撑块416的支撑面4161的第一搭接面355，第一支撑板35的第一搭接面355与第一支撑块416的支撑面4161之间形成斜面配合，有利于提高搭接面积，使得第一支撑块416对第一支撑板35的支撑更为稳定。第二支撑板36具有搭接第二支撑块417的支撑面4171的第一搭接面365，第二支撑板36的第一搭接面365与第二支撑块417的支撑面4171之间形成斜面配合，有利于提高搭接面积，使得第二支撑块417对第二支撑板36的支撑更为稳定。
请再次参阅图35，折叠组件12处于打开状态时，第一支撑板35还可以搭接第一摆臂325，例如搭接于第一摆臂325的转动端3251和/或连接段3253；第二支撑板36还可以搭接第二摆臂326，例如搭接于第二摆臂326的转动端3261和/或连接段3263。在本实施例中，折叠组件12处于打开状态时，由于第一摆臂325的转动端3251和/或连接段3253能够为第一支撑板35提供刚性支撑，第二摆臂326的转动端3261和/或连接段3263能够为第二支撑板36提供刚性支撑，因此能够通过搭接设计，提高第一支撑板35和第二支撑板36的局部刚度，减小第一支撑板35和第二支撑板36的按压虚位，以提升屏幕2的可靠性。
示例性的，第一支撑板35具有搭接第一摆臂325的第二搭接面356，第一支撑板35的第二搭接面356与第一摆臂325之间形成斜面配合，不仅有利于提高搭接面积，使得第一摆臂325对第一支撑板35的支撑更为稳定，还能够使第一支撑板35与第一摆臂325的相对运动不易干涉、更为顺畅。第二支撑板36具有搭接第二摆臂326的第二搭接面366，第二支撑板36的第二搭接面366与第二摆臂326之间形成斜面配合，不仅有利于提高搭接面积，使得第二摆臂326对第二支撑板36的支撑更为稳定，还能够使第二支撑板36与第二摆臂326的相对运动不易干涉、更为顺畅。
请结合参阅图8和图37，图37是图5所示折叠组件12沿I-I处剖开的截面结构示意图。
一些实施例中，在折叠组件12处于打开状态时，第一支撑板35还可以搭接顶部罩体42的多个第三支撑块421，第二支撑板36还可以搭接顶部罩体42的多个第四支撑块422。其中，主轴31的其他罩体(如中部罩体43或底部罩体44)也可以设有第三支撑块421和第四支撑块422，同样可以用于分别与第一支撑板35和第二支撑板36搭接，此处不再赘述。
在本实施例中，由于第三支撑块421向靠近主支撑板41的方向凸起，第三支撑块421与第一支撑块416错位排布，第三支撑块421与第一支撑块416的支撑面4161靠近，因此第三支撑块421和第一支撑块416能够更好地同时支撑第一支撑板35，并且对第一支撑板35的结构要求较低，支撑结构易实现。同样的，由于第四支撑块422向靠近主支撑板41的方向凸起，第四支撑块422与第二支撑块417错位排布，第四支撑块422与第二支撑块417的支撑面4171靠近，因此第四支撑块422和第二支撑块417能够更好地同时支撑第二支撑板36，并且对第二支撑板36的结构要求较低，支撑结构易实现。
示例性的，第一支撑板35具有搭接顶部罩体42的多个第三支撑块421的第三搭接面357，第一支撑板35的第三搭接面357与顶部罩体42的多个第三支撑块421之间形成斜面配合，不仅有利于提高搭接面积，使得顶部罩体42的多个第三支撑块421对第一支撑板35的支撑更为稳定，还能够使第一支撑板35与顶部罩体42的多个第三支撑块421的相对运动不易干涉、更为顺畅。第二支撑板36具有搭接顶部罩体42的多个第四支撑块422的第三搭接面367，第二支撑板36的第三搭接面367与顶部罩体42的多个第四支撑块422之间形成斜面配合，不仅有利于提高搭接面积，使得顶部罩体42的多个第四支撑块422对第二支撑板36的支撑更为稳定，还能够使第二支撑板36与顶部罩体42的多个第四支撑块422的相对运动不易干涉、更为顺畅。
在本申请实施例中，在折叠组件12处于闭合状态时，第一支撑板35和第二支撑板36可以搭接固定架及连接组件的部分运动件，使得固定架及运动件能够为第一支撑板35和第二支撑板36提供刚性支撑，第一支撑板35和第二支撑板36能够与主轴31配合、形成稳定性更好的收容空间，以更好地容纳屏幕2，提升屏幕2的可靠性。以下进行举例说明。
请结合参阅图38至图40，图38是图3所示电子设备200沿J-J处剖开的截面结构示意图，图39是图3所示电子设备200沿K-K处剖开的截面结构示意图，图40是图3所示电子设备200沿L-L处剖开的截面结构示意图。
一些实施例中，在折叠组件12处于闭合状态时，如图38所示，第一支撑板35搭接第一摆臂325，第二支撑板36搭接第二摆臂326；如图39所示，第一支撑板35搭接第一固定架321，第二支撑板36搭接第二固定架322；如图40所示，第一支撑板35搭接第一连接臂323，第二支撑板36搭接第二连接臂324。此时，连接组件的摆臂、固定架及连接臂均能够为支撑板提供刚性支撑，使得第一支撑板35和第二支撑板36的相对位置稳定，为屏幕2的折弯部22提供稳定的支撑环境，第一支撑板35和第二支撑板36更易维持屏幕2的折弯部22的水 滴状，有利于提高屏幕2的可靠性。
