折叠组件及电子设备
本申请要求于2023年02月01日提交国家知识产权局、申请号为202310130418.3、发明名称为“折叠组件及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子设备技术领域，尤其涉及一种折叠组件及包括该折叠组件的电子设备。
背景技术
随着科技的进步，大屏智能电子设备时代来临，为了解决传统的大屏直板设备尺寸大不方便携带的问题，具有可折叠的电子设备应运而生。
在用户需要大屏显示时，电子设备可以展开为用户提供大屏画面，满足用户的大屏显示需求；在用户需要随身携带时，电子设备又可以折叠以减少收纳所需的空间，便于用户随身携带。
在可折叠的电子设备中，一般通过折叠组件实现电子设备的可折叠功能。折叠组件的结构设计以及结构之间的布局，直接影响着可折叠的电子设备折叠后的尺寸，以及折叠组件的机械稳定性和可靠性。目前可折叠的电子设备中，折叠组件内部的结构繁多，导致折叠组件结构复杂且成本较高。
发明内容
本申请实施例提供一种折叠组件及电子设备，能够解决折叠组件结构复杂且成本较高的问题。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种折叠组件。该折叠组件应用于电子设备，电子设备包括柔性屏。折叠组件包括基座、摆臂机构、门板机构和弹性支撑件。基座沿第一方向延伸。摆臂机构包括第一摆臂和第二摆臂。在第二方向上，第一摆臂和第二摆臂分别位于基座的两侧并与基座铰接。第一摆臂和第二摆臂在折叠位置和展开位置之间转动。第二方向与第一方向交叉。门板机构位于摆臂机构靠近柔性屏的一侧。门板机构包括第一门板和第二门板。第一门板设置于第一摆臂上，第二门板设置于第二摆臂上。第一门板与第一摆臂共同转动，第二门板与第二摆臂共同转动。弹性支撑件位于门板机构靠近柔性屏的一侧。弹性支撑件在第二方向的两个端部分别与第一门板和第二门板连接。其中，在第一摆臂和第二摆臂处于展开位置时，弹性支撑件处于平板状态用于支撑柔性屏；在第一摆臂和第二摆臂处于折叠位置时，弹性支撑件弯折形成避让空间用于容纳部分柔性屏。
第一摆臂分别与第一门板和基座连接，在第一摆臂相对基座转动的过程中，第一门板会随着第一摆臂相对基座转动。类似地，第二摆臂分别与第二门板和基座连接，在第二摆臂相对基座转动的过程中，第二门板会随着第二摆臂相对基座转动。
需要说明的是，在第一摆臂和第一门板共同转动的同时，第一摆臂和第一门板之 间也可以相对转动；同样的，在第二摆臂和第二门板共同转动的同时，第二摆臂和第二门板之间也可以相对转动。
电子设备由展开状态向折叠状态切换的过程中，第一门板和第二门板远离基座的端部相互靠拢，第一门板和第二门板靠近基座的端部相互远离，使得柔性屏在第一门板和第二门板之间弯折。从而，第一门板、基座和第二门板形成了接近三角形的容纳腔，柔性屏的玩着部分被容纳在三角形的容纳腔内，并可呈类水滴状。这样可以增大柔性屏玩着部分的内折角，提高柔性屏的使用寿命。当电子设备由折叠状态向展开状态切换时，第一门板和第二门板相互背离，直至第一门板、基座和第二门板共面且朝向相同，从而使得柔性屏展开，并且支撑柔性屏。
在电子设备从展开状态切换至折叠状态的过程中，第一门板和第二门板相向转动，从而带动弹性支撑件在第二方向上的两个端部相向转动，实现对弹性支撑件的折叠。在电子设备处于折叠状态下，弹性支撑件向远离柔性屏的方向弯折，形成用于容纳部分柔性屏的避让空间。示例性地，避让空间可以为类水滴状，用于容纳折叠状态下柔性屏的弯折部分。弹性支撑件包围柔性屏的弯折部分以防止其他部件对弯折部分的挤压，延长柔性屏的使用寿命。
电子设备从折叠状态切换至展开状态的过程中，第一门板和第二门板相背转动，从而带动弹性支撑件在第二方向上的两个端部相背转动，实现对弹性支撑件的展开。在电子设备处于展开状态下，弹性支撑件展开为平板状态，能够与柔性屏的弯折部分直接接触以支撑弯折部分。这样，能够简化折叠组件的结构，得到结构简单且成本低的折叠组件，进而降低电子设备的成本。
在第一方面的一些实施例中，弹性支撑件开设有多个贯穿弹性支撑件的开口。
开口的数量可以为多个，多个开口可以阵列排布，也可以无规则排布，此处不作限定。
多个开口的形状可以相同，也可以不同。例如，一些开口的形状为圆形，另一些开口的形状为椭圆形，又一些开口的形状为矩形等等。另外，多个开口的开口面积可以相等，也可以不等。例如，不同形状的开口的开口面积不同；又例如，相同形状的开口的开口面积也可以不同。
示例性地，开口为长条形，开口的长度方向与第一方向平行，多个长条形开口阵列排布设置，且各个长条形开口的开口面积相等。
本实施例中，通过对弹性支撑件开设开口，能够降低弹性支撑件随门板机构运动弯折而受到的弯折应力，便于弹性支撑件发生弯折。
在第一方面的一些实施例中，在第一摆臂和第二摆臂均处于展开位置的情况下，弹性支撑件在柔性屏上的正投影覆盖基座在柔性屏上的正投影。
可以理解地，在第一方向和第二方向组成的平面上，弹性支撑件的面积大于基座的面积。这样，弹性支撑件通过与第一门板和第二门板连接，能够将基座与柔性屏分隔，并且增加弹性支撑件对柔性屏的支撑面积，提升对柔性屏的支撑效果。
在第一方面的一些实施例中，弹性支撑件利用螺钉固定连接于第一门板。通过螺钉能够将弹性支撑件的端部固定于第一门板上，提高弹性支撑件与第一门板之间的固定强度，从而提升弹性支撑件的可靠性。
在第一方面的一些实施例中，弹性支撑件利用螺钉固定连接于第二门板。通过螺钉能够将弹性支撑件的端部固定于第二门板上，提高弹性支撑件与第二门板之间的固定强度，从而提升弹性支撑件的可靠性。
在第一方面的一些实施例中，第一摆臂包括多个第一主摆臂和多个第一副摆臂。多个第一主摆臂和多个第一副摆臂在第一方向上交替排布。这样，能够优化第一主摆臂和第一副摆臂相对基座的受力分布，提升多个第一摆臂运动的平稳性。
在第一方面的一些实施例中，第二摆臂包括多个第二主摆臂和多个第二副摆臂；多个第二主摆臂和多个第二副摆臂在第一方向上交替排布。这样，能够优化第二主摆臂和第二副摆臂相对基座的受力分布，提升多个第二摆臂运动的平稳性。
在第一方面的一些实施例中，第一门板包括第一门板主体、以及自第一门板主体向靠近摆臂机构一侧延伸的第一配套件。第一配套件上开设有第一滑动槽；第一副摆臂上设有第一插销，第一插销插入第一滑动槽内。
第一滑动槽包括第一端位置和第二端位置。在电子设备由展开状态向折叠状态切换的过程中，第一插销从第一滑动槽的第一端位置运动至第二端位置，从而使得第一门板远离基座的端部向内折叠运动，第一门板靠近基座的端部向外展开运动。在电子设备由折叠状态向展开状态切换的过程中，第一插销从第一滑动槽的第二端位置运动至第一端位置，从而使得第一门板远离基座的端部向外扩张运动，第一门板靠近基座的端部向内折叠运动。
第一滑动槽能够让第一门板相对第一副摆臂实现滑动转动连接，使得在电子设备处于折叠状态时第一门板内收形成接近三角形的容纳腔，在电子设备处于展开状态时第一门板外展形成用于支撑柔性屏的支撑面。其中，第一滑动槽的两个端位置能够对第一门板的滑动转动进行限位，提高第一门板运动的可靠性。
在第一方面的一些实施例中，第二门板包括第二门板主体、以及自第二门板主体向靠近摆臂机构一侧延伸的第二配套件；第二配套件上开设有第二滑动槽；第二副摆臂上设有第二插销，第二插销插入第二滑动槽内。
第二滑动槽包括第一端位置和第二端位置。在电子设备由展开状态向折叠状态切换的过程中，第二插销从第二滑动槽的第一端位置运动至第二端位置，从而使得第二门板远离基座的端部向内折叠运动，第二门板靠近基座的端部向外展开运动。在电子设备由折叠状态向展开状态切换的过程中，第二插销从第二滑动槽的第二端位置运动至第一端位置，从而使得第二门板远离基座的端部向外展开运动，第二门板靠近基座的端部向内折叠运动。
第二滑动槽能够让第二门板相对第二副摆臂实现滑动转动连接，使得在电子设备处于折叠状态时第二门板内收形成接近三角形的容纳腔，在电子设备处于展开状态时第二门板外展形成用于支撑柔性屏的支撑面。其中，第二滑动槽的两个端位置能够对第二门板的滑动转动进行限位，提高第二门板运动的可靠性。
在第一方面的一些实施例中，第一滑动槽和第二滑动槽为弧形槽，弧形槽向远离柔性屏的方向凸起。
在第一方面的一些实施例中，折叠组件还包括阻尼机构。阻尼机构位于基座靠近柔性屏的一侧；包括阻尼弹簧、以及与阻尼弹簧连接的凹轮。第一摆臂和/或第二摆臂 包括凸轮，凸轮与凹轮配合，以在摆臂机构转动时压缩阻尼弹簧。
示例性地，第一副摆臂与基座铰接的凸轮具有凸面，凹轮具有凹面，凸轮上的凸面与凹轮上的凹面相适配。
第一摆臂相对基座转动以及第二摆臂相对基座转动时，凹轮上的凹面与凸轮上的其中一个凸面配合而逐渐地切换到与另一个凸面配合。在此过程中阻尼弹簧所受的压力先逐渐地增大，然后逐渐地被释放，同时凹轮随着阻尼弹簧所受的压力的变化而产生轴向位移，这样，可以便于折叠组件在折叠状态和展开状态切换。在无用户作用的外力时，通过利用阻尼弹簧的弹力可以为第一摆臂相对基座转动以及第二摆臂相对基座转动提供阻尼力，从而便于折叠组件维持在当前的折叠状态或展开状态。
在第一方面的一些实施例中，折叠组件还包括同步机构。同步机构包括第一内齿轮、第二内齿轮、第一外齿轮和第二外齿轮。第一内齿轮和第二内齿轮共同位于第一外齿轮和第二外齿轮之间，且第一内齿轮和第二内齿轮相互啮合，第一外齿轮与第一内齿轮啮合，第二外齿轮与第二内齿轮啮合。第一外齿轮与第一摆臂固定连接，第二外齿轮与第二摆臂固定连接。
示例性地，第一内齿轮的尺寸和第二内齿轮的尺寸相等，第一外齿轮的尺寸和第二外齿轮的尺寸相等，第一外齿轮的尺寸大于第一内齿轮的尺寸。
由于沿第二方向，第一外齿轮、第一内齿轮、第二内齿轮和第二外齿轮依次啮合，因此第一外轮齿和第二外齿轮的旋转方向相反且角速度相等。
在一些实施例中，第一外齿轮与第一副摆固定连接，第二外齿轮与第二副摆臂固定连接。示例性地，第一外齿轮的齿轴与第一副摆臂的凸轮为相互连接的一体结构，第二外齿轮的齿轴与第二副摆臂的凸轮为相互连接的一体结构。从而第一外齿轮可以与第一副摆臂实现角速度同步，第二外齿轮可以与第二副摆臂实现角速度同步。
可以理解地，同步机构能够使得第一摆臂和第二摆臂相对于基座同步转动，进而提高电子设备在展开状态与折叠状态之间运动的同步性。
第二方面，提供一种电子设备。该电子设备包括柔性屏以及如上第一方面任一种可能的折叠组件。折叠组件处于展开状态时支撑柔性屏，折叠组件处于折叠状态时收纳柔性屏。
可以理解地，上述提供的任一种电子设备，均可以由上文所提供的对应的折叠组件来实现，或与上文所提供的对应的折叠组件相关联，因此，其所能达到的有益效果可参考上文所提供的折叠组件中的有益效果，此处不再赘述。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
以下，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
此外，本申请中，“上”、“下”等方位术语是相对于附图中的部件示意置放的方位来定义的，应当理解到，这些方向性术语是相对的概念，它们用于相对于的描述和澄清，其可以根据附图中部件所放置的方位的变化而相应地发生变化。
图1为申请的一些实施例提供的电子设备的结构示意图。
如图1所示，本申请提供一种电子设备100，该电子设备为可折叠的一类电子设备。可折叠的电子设备可以包括具有柔性屏且可改变柔性屏及自身的展开状态或折叠状态的各种电子设备。在不同的使用需求下，可折叠的电子设备可以展开至展开状态，也可以折叠至折叠状态，还可以处于展开状态与折叠状态之间的中间悬停状态，也即中间悬停状态处于电子设备在折叠状态和展开状态之间切换的切换路径上。因此，可折叠的电子设备至少具有两种状态，即展开状态和折叠状态。在一些情况下，还可以进一步包括第三种状态，即位于展开状态和折叠状态之间的中间悬停状态。可以理解的是，中间悬停状态并不是只具有唯一的状态，可以是电子设备处于展开状态和折叠状态之间的切换路径的任意一种或多种状态。
如图1所示，电子设备100可以包括柔性屏10和支撑装置20。可以理解的是，图1仅示意性的示出了电子设备100包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图2的限制。
柔性屏10能够用于显示信息并为用户提供交互界面。在本申请各实施例中，柔性屏10可以包括但不限于有机发光二极管(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，迷你发光二极管(mini organic light-emitting diode)显示屏，微型发光二极管(micro organic light-emitting diode)显示屏，微型有机发光 二极管(micro organic light-emitting diode)显示屏，量子点发光二极管(quantum dot light emitting diodes，QLED)显示屏等。
柔性屏10能够在展开状态与折叠状态之间切换。柔性屏10包括第一部分11、第二部分12和第三部分13，第三部分13位于第一部分11和第二部分12之间。柔性屏10的至少第三部分13采用柔性材料制作。可以理解地，第三部分13为柔性屏10的弯折部分，采用柔性材料制作；第一部分11和第二部分12可以采用柔性材料制作，也可以采用刚性材料制作，还可以部分采用刚性材料、部分采用柔性材料制作，此处不作限定。
请参阅图2，图2为本申请的实施例提供的电子设备100处于展开状态的的立体图。当柔性屏10处于展开状态时，第一部分11、第二部分12和第三部分13共平面设置，且朝向相同。在此状态下，能够实现大屏显示，可以给用户提供更丰富的信息，带给用户更好的使用体验。
请参阅图3，图3为本申请实施例提供的电子设备100处于折叠状态的的立体图。当柔性屏10处于折叠状态时，第三部分13处于折弯状态，第一部分11(图3中未示出)与第二部分12(图3中未示出)相对。在此状态下，柔性屏10对用户不可见，支撑装置20保护于柔性屏10外，以防止柔性屏10被硬物刮伤。同时，在此状态下，可以减小可折叠电子设备100的体积，便于可折叠电子设备100的收纳。
支撑装置20用于支撑柔性屏10，并允许柔性屏10在展开状态与折叠状态之间切换。请参阅图4，图4为根据图1-图3中所示的电子设备100中的支撑装置20的立体图。在本实施例中，支撑装置20包括第一壳体21、第二壳体22和折叠组件23。可以理解的是，图4仅示意性的示出了支撑装置20包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图4的限制。
支撑装置20具有支撑面，支撑面可以用于支撑柔性屏10。通过支撑面的支撑，在展开状态时，可以使得柔性屏10呈平板状，并且使得柔性屏10的显示面为平面。
第一壳体21用于固定并支撑图1中柔性屏10的第一部分11。具体的，第一壳体21具有支撑面M1，第一壳体21通过支撑面M1固定并支撑图1中柔性屏10的第一部分11。示例性的，支撑面M1与第一部分11的连接关系包括但不限于胶粘。
第二壳体22用于固定并支撑图1中柔性屏10的第二部分12。具体的，第二壳体22具有支撑面M2，第二壳体22通过支撑面M2固定并支撑图1中柔性屏10的第二部分12。示例性的，支撑面M2与第二部分11的连接关系包括但不限于胶粘。
第一壳体21和/或第二壳体22可以分别形成安装空间，以用于安装电子设备100的电路板、电池、受话器、扬声器、摄像头等电子元器件。其中，电路板可以集成电子设备100的主控制器、存储单元、天线模块、电源管理模块等电子元器件，电池则可以为柔性屏10、电路板、受话器、扬声器、摄像头等电子元器件供电。第一壳体21与第二壳体22可以是等厚的也可以是不等厚的，本申请实施例不作限定。
在一些实施例中，第一壳体21和第二壳体22可以都设有安装空间，将上述电子设备100的电子元器件分布于两侧壳体中。在另一些实施例中，可以仅在第一壳体21中设有安装空间，将上述电子设备100的电子元器件集中分布于第一壳体21中；或者，第一壳体21和第二壳体22都可以设有安装空间，但是上述电子设备100的元器 件中的大部分设于第二壳体22中，小部分设于第一壳体21中，使第一壳体21更加轻巧，从而可以更便捷的进行折叠和展开。
第一壳体21可以为一个结构整体，也可以由多个部分装配形成。同理的，第二壳体22可以为一个结构件整体，也可以由多个部分装配形成。
折叠组件23用于支撑柔性屏10的第三部分13。示例性地，折叠组件23位于第一壳体21和第二壳体22之间，折叠组件23分别与第一壳体21和第二壳体22连接，第一壳体21与第二壳体22通过折叠组件23实现可转动连接，从而实现第一壳体21和第二壳体22之间的相对转动。具体的，如图4所示，第一壳体21相对第二壳体22转动的转动轴线沿第一方向X延伸。
折叠组件23可以在展开状态和折叠状态之间切换。通过折叠组件23在展开状态和折叠状态之间的切换，从而可以允许整个电子设备100和/或柔性屏10在展开状态和折叠状态之间切换。
具体而言，请参阅图5，图5为根据图3和图4中所示的支撑装置20的局部侧视图。折叠组件23在由展开状态向折叠状态切换的过程中，可以带动第一壳体21和第二壳体22相向转动，在此过程中，第一壳体21的转动方向(如图5中的箭头P1所指示的方向)与第二壳体22的转动方向(如图5中的箭头P2所指示的方向)相反。当折叠组件23切换至折叠状态时，第一壳体21和第二壳体22彼此面对，且第一壳体21的支撑面M1和第二壳体22的支撑面M2彼此面对，此时第一壳体21的支撑面M1和第二壳体22的支撑面M2之间可以存在微小的夹角或相互平行以使两个壳体能完全合拢，从而实现第一壳体21和第二壳体22的折叠，使得柔性屏10的第一部分11和第二部分12可以相对设置，将电子设备100整体切换至折叠状态。折叠组件23在由折叠状态向展开状态切换的过程中，可以带动第一壳体21和第二壳体22相背转动，在此过程中，第一壳体21的转动方向(如图5中的箭头Q1所指示的方向)与第二壳体22的转动方向(如图5中的箭头Q2所指示的方向)相反。当折叠组件23切换至展开状态时，第一壳体21的支撑面M1和第二壳体22的支撑面M2共面且朝向相同。从而实现第一壳体21和第二壳体22的展开，以便于柔性屏10的第一部分11和第二部分12共面且朝向相同，将电子设备100整体切换至展开状态。
其中，第一壳体21的支撑面M1和第二壳体22的支撑面M2共面且朝向相同，是指第一壳体21的支撑面M1和第二壳体22的支撑面M2可以呈180°，当然也允许存在一定角度的公差，例如，±10°以内的公差，换言之，第一壳体21的支撑面M1和第二壳体22的支撑面M2夹角的取值范围介于170°到190°之间。
请继续参阅图4和图5，折叠组件23可以包括：基座24、摆臂机构25、门板机构26和弹性支撑件27。图5仅示意性的示出了折叠组件23包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图5的限制。上述第一方向X是垂直于图5纸面的方向，第二方向Y是截面方向。
基座24具有支撑面M4，在展开状态时，基座24上的支撑面M4用于支撑柔性屏10的第三部分13，从而可以保证在展开状态时，柔性屏10的平整性；在折叠状态时，柔性屏10的第三部分13弯折，第三部分13与基座24保持一定的间隙，以避免柔性屏10发生弯折变形而与基座24挤压造成损坏。
具体的，在电子设备100的折叠状态，基座24的支撑面M4与第一壳体21的支撑面M1垂直(但在实际场景中，也允许存在一定角度的公差，例如第一壳体21的支撑面M1和基座24的支撑面M4夹角的取值范围介于80°到100°之间)。基座24的支撑面M4与第二壳体22的支撑面M2垂直(但在实际场景中，也允许存在一定角度的公差，例如，第二壳体22的支撑面M2和基座24的支撑面M4夹角的取值范围介于80°到100°之间)。
基座24在第一方向X上延伸。也就是说，基座24的长度方向为第一方向X。使得基座24的长度方向与处于折叠状态下的电子设备100的长度方向一致，有利于增大基座24上支撑面M4的长度，从而增大支撑面M4的面积。以便于该支撑面M4能够对柔性屏10的第三部分13可靠支撑。
为了在电子设备100处于折叠状态时，能够使得柔性屏10的内折角尽量小，而将柔性屏10折叠成水滴状。这样，增大第三部分13的内折角，能够提高柔性屏10的使用寿命。
门板机构26包括第一门板261和第二门板262。第一门板261和第二门板262布设在基座24在第二方向Y(垂直于第一方向X)上的相对的两侧。第一门板261和第二门板262分别形成为平板状。
具体的，第一门板261具有支撑面M5，第二门板262具有支撑面M6。支撑面M5和支撑面M6均与柔性屏10的第三部分13贴合，以支撑柔性屏10的第三部分13。其中，支撑面M5位于支撑面M4和支撑面M1之间(结合图4)，支撑面M6位于支撑面M4和支撑面M2之间(结合图4)。并且，摆臂机构25能够允许第一门板261相对基座24转动，且第二门板262也相对基座24转动。
电子设备100由展开状态向折叠状态切换的过程中，如图5所示，第一门板261相对基座24沿旋转方向P1方向转动，第二门板262相对基座24沿与P1方向相反的P2方向转动。也即，第一门板261和第二门板262远离基座24的端部相互靠拢，第一门板261和第二门板262靠近基座24的端部相互远离，使得柔性屏10在第一门板261和第二门板262之间弯折。从而，第一门板261、基座24和第二门板262形成了接近三角形的容纳腔，柔性屏10的第三部分13被容纳在三角形的容纳腔内，并可呈类水滴状。这样可以增大第三部分13的内折角，提高柔性屏10的使用寿命。
相反的，当电子设备100由折叠状态向展开状态切换时，第一门板261相对基座24沿与旋转方向P1相反的方向(如图5中的Q1所指示的方向)转动，第二门板262相对基座24沿与P2方向相反的方向(如图5中的Q2所指示的方向)转动。也即，第一门板261和第二门板262相互背离，直至第一门板261的支撑面M5、基座24的支撑面M4和第二门板262的支撑面M6共面且朝向相同，从而使得柔性屏10展开，并且支撑柔性屏10。
其中，可以理解的是，第一门板261的支撑面M5、基座24的支撑面M4和第二门板262的支撑面M6共面是指，第一门板261的支撑面M5、基座24的支撑面M4和第二门板262的支撑面M6任意两者之间的夹角为180°，当然在实际场景中也允许存在一定的误差，例如，任意两者之间的夹角的取值范围介于170°到190°之间。

在一些示例中，可以是第一主摆臂251a与第一壳体21固定连接，而第一副摆臂251b不与第一壳体21连接。在另一些示例中，也可以是第一主摆臂251a不与第一壳体21连接，而第一副摆臂251b与第一壳体21固定连接。在其他的示例中，还可以是第一主摆臂251a与第一壳体21固定连接，且第一副摆臂251b也与第一壳体21固定连接，此处不做限定。

第二摆臂252的数量可以为多个。多个第二摆臂252可以包括至少一个第二主摆臂252a和至少一个第二副摆臂252b。示例性地，多个第二主摆臂252a和多个第二副摆臂252b可以沿第一方向X交替排布设置。这样，能够优化第二主摆臂252a和第二副摆臂252b相对基座24的受力分布，提升多个第二摆臂252运动的平稳性。
在一些示例中，可以是第二主摆臂252a与第二壳体22固定连接，而第二副摆臂 252b不与第二壳体22连接。在另一些示例中，也可以是第二主摆臂252a不与第二壳体22连接，而第二副摆臂252b与第二壳体22固定连接。在其他的示例中，还可以是第二主摆臂252a与第二壳体22固定连接，且第二副摆臂252b也与第二壳体22固定连接，此处不做限定。
第一主摆臂251a和第二主摆臂252a的数量可以相等。在一些示例中，多个第一主摆臂251a和多个第二主摆臂252a可以相对于沿第一方向X延伸的基座24对称设置。类似地，第一副摆臂251b和第二副摆臂252b的数量可以相等。在一些示例中，多个第一副摆臂251b和多个第二副摆臂252b可以相对于沿第一方向X延伸的基座24对称设置。
如图8和图9所示，摆臂机构25还可以包括第一连接块253和第二连接块254。第一连接块253与第一壳体21和第一摆臂251位于基座24的同一侧，第二连接块254与第二壳体22和第二摆臂252位于基座24的同一侧。
每个第一连接块253用于连接至少一个第一主摆臂251a和至少一个第一副摆臂251b，使得连接同一个第一连接块253的第一主摆臂251a和第一副摆臂251b相对基座24同步转动，提高多个第一摆臂251转动的同步性。第一连接块253的数量可以为一个或多个。第一连接块253的数量为一个时，多个第一主摆臂251a和多个第一副摆臂251b连接同一个第一连接块253。第一连接块253的数量为多个时，不同的第一连接块253可以连接不同的第一主摆臂251a和第一副摆臂251b。
类似地，每个第二连接块254用于连接至少一个第二主摆臂252a和至少一个第二副摆臂252b，使得连接同一个第二连接块254的第二主摆臂252a和第二副摆臂252b相对基座24同步转动，提高多个第二摆臂252转动的同步性。第二连接块254的数量可以为一个或多个。第二连接块254的数量为一个时，多个第二主摆臂252a和多个第二副摆臂252b连接同一个第二连接块254。第二连接块254的数量为多个时，不同的第二连接块254可以连接不同的第二主摆臂252a和第二副摆臂252b。
请参阅图10至图12，图10为图4和图5所示的折叠组件23的立体结构示意图，其中，折叠组件23处于折叠状态；图11为沿图10中C-C线形成的剖视图；图12为沿图10中D-D线形成的剖视图；图13为沿图6中E-E线形成的剖视图。
第一连接块253和第二连接块254可以为楔形结构。在电子设备100由展开状态向折叠状态切换的过程中，第一连接块253和第二连接块254相对设置，具体的第一连接块253的楔形面与第二连接块254的楔形面相对设置，从而第一连接块253的楔形面、基座24和第二连接块254的楔形面形成了接近三角形的容纳腔，柔性屏10的第三部分13被容纳在三角形的容纳腔内，并可呈类水滴状。这样可以增大第三部分13的内折角，提高柔性屏10的使用寿命。
在一些实施例中，第一连接块253可以与第一摆臂251连接。第一连接块253与第一门板261转动连接。示例性地，第一连接块253与第一门板261通过转动副连接，其中，转动副的公共轴沿第一方向X延伸。这样，第一门板261能够通过转动副相对于第一连接块253和第一摆臂251转动。
类似地，第二连接块254可以与第二摆臂252连接。第二连接块254与第二门板262转动连接。示例性地，第二连接块254与第二门板262通过转动副连接，其中， 转动副的公共轴沿第一方向X延伸。这样，第二门板262能够通过转动副相对于第二连接块254和第二摆臂252转动。
其中，第一连接块253可以与第一摆臂251固定连接或活动连接；第二连接块254可以与第二摆臂252固定连接或活动连接；此处不作限定。
如图12和图13所示，第一门板261包括第一门板主体2611、以及自第一门板主体2611向靠近摆臂机构25一侧延伸的第一配套件2612。第一配套件2612可以垂直于第一门板主体2611向靠近摆臂机构25一侧设置。第一配套件2612可以开设有第一滑动槽2613，第一副摆臂251b上可以设有第一插销255，第一插销255插入第一滑动槽2613内，从而实现第一门板261与第一副摆臂251b滑动转动连接。
如图12和图13所示，第一滑动槽2613包括第一端位置A和第二端位置B。在电子设备100由展开状态向折叠状态切换的过程中，第一插销255从第一滑动槽2613的第一端位置A运动至第二端位置B，从而使得第一门板261远离基座24的端部向P1所示的方向运动，第一门板261靠近基座24的端部向Q1所示的方向运动。在电子设备100由折叠状态向展开状态切换的过程中，第一插销255从第一滑动槽2613的第二端位置B运动至第一端位置A，从而使得第一门板261远离基座24的端部向Q1所示的方向运动，第一门板261靠近基座24的端部向P1所示的方向运动。
第一滑动槽2613能够让第一门板261相对第一副摆臂251b实现滑动转动连接，使得在电子设备100处于折叠状态时第一门板261内收形成接近三角形的容纳腔，在电子设备100处于展开状态时第一门板261外展形成用于支撑柔性屏10的支撑面。其中，第一滑动槽2613的两个端位置能够对第一门板261的滑动转动进行限位，提高第一门板261运动的可靠性。
如图12和图13所示，第二门板262包括第二门板主体2621、以及自第二门板主体2621向靠近摆臂机构25一侧延伸的第二配套件2622。第二配套件2622可以垂直于第二门板主体2621向靠近摆臂机构25一侧设置。第二配套件2622可以开设有第二滑动槽2623，第二副摆臂252b上可以设有第二插销256，第二插销256插入第二滑动槽2623内，从而实现第二门板262与第二副摆臂252b滑动转动连接。
如图12和图13所示，第二滑动槽2623包括第一端位置A和第二端位置B。在电子设备100由展开状态向折叠状态切换的过程中，第二插销256从第二滑动槽2623的第一端位置A运动至第二端位置B，从而使得第二门板262远离基座24的端部向P2所示的方向运动，第二门板262靠近基座24的端部向Q2所示的方向运动。在电子设备100由折叠状态向展开状态切换的过程中，第二插销256从第二滑动槽2623的第二端位置B运动至第一端位置A，从而使得第二门板262远离基座24的端部向Q2所示的方向运动，第二门板262靠近基座24的端部向P2所示的方向运动。
第二滑动槽2623能够让第二门板262相对第二副摆臂252b实现滑动转动连接，使得在电子设备100处于折叠状态时第二门板262内收形成接近三角形的容纳腔，在电子设备100处于展开状态时第二门板262外展形成用于支撑柔性屏10的支撑面。其中，第二滑动槽2623的两个端位置能够对第二门板262的滑动转动进行限位，提高第二门板262运动的可靠性。
其中，第一滑动槽2613和第二滑动槽2623均为弧形槽，弧形槽向远离柔性屏10 的方向凸起。在其他的一些实施例中，第一插销255也可以是设置于第一主摆臂251a上，第二插销256也可以是设置于第二主摆臂252a上，此处不作限定。
在电子设备100由展开状态向折叠状态切换的过程中，第一门板261和第二门板262相对设置，第一门板261远离基座24的端部向P1所示的方向运动，第一门板261靠近基座24的端部向Q1所示的方向运动；第二门板262远离基座24的端部向P2所示的方向运动，第二门板262靠近基座24的端部向Q2所示的方向运动。这样，实现上述第一门板261、基座24和第二门板262形成了接近三角形的容纳腔，柔性屏10的第三部分13被容纳在三角形的容纳腔内，并可呈类水滴状。这样可以增大第三部分13的内折角，提高柔性屏10的使用寿命。
在电子设备100由折叠状态向展开状态切换的过程中，第一门板261远离基座24的端部向Q1所示的方向运动，第一门板261靠近基座24的端部向P1所示的方向运动；第二门板262远离基座24的端部向Q2所示的方向运动，第二门板262靠近基座24的端部向P2所示的方向运动。这样，实现上述第一门板261的支撑面M5、基座24的支撑面M4和第二门板262的支撑面M6共面且朝向相同，从而使得柔性屏10展开，并且支撑柔性屏10。
请参阅图14，图14为折叠组件中阻尼机构和两个副摆臂的结构示意图。在一些实施例中，折叠组件23还包括阻尼机构28。阻尼机构28包括阻尼弹簧281和凹轮282。示例性地，第一副摆臂251b与基座24铰接的凸轮2511具有凸面，凹轮282具有凹面，凸轮2511上的凸面与凹轮282上的凹面相适配。
结合图15，图15为根据图14中H区域的放大图；第一副摆臂251b上的第一凸轮2511的朝向对应的凹轮282的表面具有凸面S1和相对该凸面S1凹陷的凹面S2。第二副摆臂252b上的第二凸轮2521的朝向对应的凹轮282的表面也具有凸面S1和相对该凸面S1凹陷的凹面S2。每个凸轮上的凸面S1和凹面S2在凸轮的周向上交替排布。每个凹轮282的朝向对应的凸轮的表面也具有沿凹轮282的周向交替排布的凹面S4和凸面S3。凹轮282被预压在阻尼弹簧281和凸轮之间。在折叠状态和展开状态，凹轮282上的凸面S3与凸轮上的不同的凹面S2适配，同样的，凸轮上的凸面S1与凹轮282上的不同的凹面S4适配。
当用户驱动第一壳体21和第二壳体22，以使得第一摆臂251相对基座24转动以及第二摆臂252相对基座24转动，凹轮282上的凸面S3由与凸轮上的其中一个凹面S2配合而逐渐地切换到与另一个凹面S2配合。在此过程中阻尼弹簧281所受的压力先逐渐地增大，然后逐渐地被释放，同时凹轮282随着阻尼弹簧281所受的压力的变化而产生轴向位移，这样，可以便于折叠组件23在折叠状态和展开状态切换。在无用户作用的外力时，通过利用阻尼弹簧281的弹力可以为第一摆臂251相对基座24转动以及第二摆臂252相对基座24转动提供阻尼力，从而便于折叠组件23维持在当前的折叠状态或展开状态。
一个阻尼机构28中，阻尼弹簧281的数量可以为两个，一个阻尼弹簧281用于产生压缩弹力向第一副摆臂251b提供阻尼力，另一个阻尼弹簧281用于产生压缩弹力向第二副摆臂252b提供阻尼力。由于第一摆臂251和第二摆臂252同步转动，因此两个阻尼弹簧281共同提供电子设备100折叠过程中的阻尼力。
另外，在一些示例中，阻尼机构28还可以包括2个辅助弹簧，2个辅助弹簧位于两个阻尼弹簧281之间，用于与阻尼弹簧281同步进行压缩。从而能够增加第一摆臂251和第二摆臂252的阻尼力，提升电子设备100在处于展开状态与折叠状态之间的中间悬停状态的稳定性。
在其他的一些实施例中，与凹轮282配合的凸轮位于主摆臂与基座铰接的铰轴上，即阻尼弹簧281用于产生压缩弹力向主摆臂提供阻尼力，从而提供电子设备100折叠过程中的阻尼力。
请参阅图16和图17，图16为折叠组件中同步机构与两个副摆臂的立体结构示意图；图17为折叠组件中同步机构的剖视图。在一些实施例中，折叠组件23还包括同步机构29。同步机构29包括第一内齿轮291、第二内齿轮292、第一外齿轮293和第二外齿轮294。第一内齿轮291和第二内齿轮192共同位于第一外齿轮293和第二外齿轮294之间，且第一内齿轮291和第二内齿轮292相互啮合，第一外齿轮293与第一内齿轮291啮合，第二外齿轮294与第二内齿轮292啮合。
示例性地，第一内齿轮291的尺寸和第二内齿轮292的尺寸相等，第一外齿轮293的尺寸和第二外齿轮294的尺寸相等，第一外齿轮293的尺寸大于第一内齿轮291的尺寸。
由于沿第二方向Y，第一外齿轮293、第一内齿轮291、第二内齿轮292和第二外齿轮294依次啮合，因此第一外轮齿293和第二外齿轮294的旋转方向相反且角速度相等。
在一些实施例中，第一外齿轮293与第一副摆臂251b固定连接，第二外齿轮294与第二副摆臂252b固定连接。示例性地，如图16所示，第一外齿轮293的齿轴与第一副摆臂251b的凸轮2511为相互连接的一体结构，第二外齿轮294的齿轴与第二副摆臂252b的凸轮2511为相互连接的一体结构。从而第一外齿轮293可以与第一副摆臂251b实现角速度同步，第二外齿轮294可以与第二副摆臂252b实现角速度同步。
在电子设备100由展开状态向折叠状态切换的过程中，第一摆臂251沿P1所示的方向运动，第二摆臂252沿P2所示的方向运动，在该过程中同步机构29和第一外齿轮293固定连接的第一摆臂251沿P1所示的方向转动的角度，与和第二外齿轮294固定连接的第二摆臂252沿P2所示的方向转动的角度相等。在电子设备100由折叠状态向展开状态切换的过程中，第一摆臂251沿Q11所示的方向运动，第二摆臂252沿Q2所示的方向运动，在该过程中同步机构29和第一外齿轮293固定连接的第一摆臂251沿Q1所示的方向转动的角度，与和第二外齿轮294固定连接的第二摆臂252沿Q2所示的方向转动的角度相等。
在其他的一些实施例中，第一外齿轮293也可以不与第一副摆臂251b固定连接，而是与第一主摆臂251a固定连接；第二外齿轮294也可以不与第二副摆臂252b固定连接，而是与第二主摆臂252a固定连接。
可以理解地，同步机构29能够使得第一摆臂251和第二摆臂252相对于基座24同步转动，从而能够提高第一壳体21和第二壳体22转动的同步性，进而提高电子设备100在展开状态与折叠状态之间运动的同步性。
在一些实施例中，如图5至图7、图10至图13所示，折叠组件23还包括弹性支 撑件27。弹性支撑件27可以位于门板机构26靠近柔性屏10的一侧。弹性支撑件27可以沿第一方向X延伸，可以理解地，弹性支撑件27的长度方向为第一方向X，弹性支撑件27的宽度方向为第二方向Y。
弹性支撑件27在第二方向Y上的两个端部与门板机构26连接。示例性地，弹性支撑件27在第二方向Y上的第一端部与第一门板261连接，弹性支撑件27在第二方向Y上的第二端部与第二门板262连接。
在一些示例中，如图6和图7所示，弹性支撑件27在第二方向Y上的第一端部通过螺钉与第一门板261固定连接，弹性支撑件27在第二方向Y上的第二端部通过螺钉与第二门板262固定连接。在另一些示例中，弹性支撑件27的端部还可以通过卡扣与门板进行固定连接。在其他示例中，弹性支撑件27的端部还可以通过其他方式与门板进行固定连接，此处不作限定。
其中，通过螺钉能够将弹性支撑件的端部固定于第一门板261和第二门板262，能够提高弹性支撑件的端部与门板之间的固定强度，从而提升弹性支撑件的可靠性。
弹性支撑件27可以在弯折后具有回弹性能。在一些示例中，弹性支撑件27可以为不锈钢薄片结构，这样在弹性支撑件27处于平板状态时具有较佳的支撑性能，同时在弹性支撑件27处于折叠状态时具有较佳的弯折性能。
如图11和图12所示，在电子设备100从展开状态切换至折叠状态的过程中，第一门板261和第二门板262相向转动，从而带动弹性支撑件27在第二方向Y上的两个端部相向转动，实现对弹性支撑件27的折叠。在电子设备100处于折叠状态下，弹性支撑件27向远离柔性屏10的方向弯折，形成用于容纳部分柔性屏的避让空间。示例性地，避让空间可以为类水滴状，用于容纳折叠状态下柔性屏10的第三部分13。弹性支撑件27包围柔性屏10的第三部分13以防止其他部件对第三部分13的挤压，延长柔性屏10的使用寿命。
如图13所示，电子设备100从折叠状态切换至展开状态的过程中，第一门板261和第二门板262相背转动，从而带动弹性支撑件27在第二方向Y上的两个端部相背转动，实现对弹性支撑件27的展开。在电子设备100处于展开状态下，弹性支撑件27展开为平板状态，能够与柔性屏10的第三部分13直接接触以支撑第三部分13。
示例性地，弹性支撑件27展开为平板状态的情况下，柔性屏10也处于平面状态。此时弹性支撑件27在柔性屏10上的正投影覆盖基座24在柔性屏10上的正投影。可以理解地，在第一方向X和第二方向Y组成的平面上，弹性支撑件27的面积大于基座24的面积。这样，弹性支撑件27通过与第一门板261和第二门板262连接，能够将基座24与柔性屏10分隔，并且增加弹性支撑件27对柔性屏10的支撑面积，提升对柔性屏10的支撑效果。
在一些实施例中，如图7所示，弹性支撑件27开设有多个贯穿弹性支撑件27的开口271。开口271的数量可以为多个，多个开口271可以阵列排布，也可以无规则排布，此处不作限定。
多个开口271的形状可以相同，也可以不同。例如，一些开口271的形状为圆形，另一些开口271的形状为椭圆形，又一些开口271的形状为矩形等等。另外，多个开口271的开口面积可以相等，也可以不等。例如，不同形状的开口271的开口面积不 同；又例如，相同形状的开口271的开口面积也可以不同。
示例性地，开口271为长条形，开口271的长度方向与第一方向X平行，多个长条形开口271阵列排布设置，且各个长条形开口的开口面积相等。
本实施例中，通过对弹性支撑件27开设开口271，能够降低弹性支撑件27随门板机构26运动弯折而受到的弯折应力，便于弹性支撑件27发生弯折。
综上所述，本申请的实施例提供的折叠组件23，在电子设备100处于展开状态时利用门板机构26将弹性支撑件27展开以支撑柔性屏10；在电子设备100处于折叠状态时利用门板机构26将弹性支撑件27弯折形成避让空间以容纳柔性屏10的第三部分13，从而保护柔性屏。这样，能够简化折叠组件23的结构，得到结构简单且成本低的折叠组件23，进而降低电子设备100的成本。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
