可以理解的是，在本实施方式中，第二部分14可相对第一部分12滑动以远离或者靠近第一部分12。在本实施方式中，“第一部分12和第二部分14做相离运动”可以理解为第二部分14相对第一部分12滑动且滑动方向背离第一部分12。另外，在本实施方式中，第一部分12和第二部分14也可做相向运动，两者做相向运动可以理解为第二部分14相对第一部分12滑动且滑动方向朝向第一部分12。
还需要指出的是，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”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；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或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
请参阅图1、图4和图5，在本实施方式中，在第一部分12和第二部分14做相向运动至极限位置(即第一部分12和第二部分14相互靠近至第一部分12和第二部分14配合在一起时)时，第一部分12和第二部分14两者整体组成一个基本呈矩形体状的壳体10。请参阅图2、图6和图7，在第一部分12和第二部分14做相离运动(即两者相互远离)时，第一部分12和第二部分14两者分离。
请参阅图3、图5和图7，卷轴20转动设置在第一部分12，具体地，卷轴20转动设置在容置空间120内。也即是说，卷轴20安装在第一部分12且可相对第一部分12转动。卷轴20用于与驱动机构70连接以使卷轴20能够在驱动机构70的驱动下相对于第一部分12转动以释放或者卷起柔性显示屏组件30。
可以理解的是，卷轴20转动设置在第一部分12可以指卷轴20直接地安装在第一部分12，也可以指卷轴20通过其它介质安装在第一部分12。
此外，请继续参阅图5和图7，柔性显示屏组件30的一端固定连接在第二部分14，另一端卷绕设置在卷轴20上。卷轴20可用于卷起柔性显示屏组件30和释放柔性显示屏组件30。其中，在第一部分12和第二部分14做相离运动时，卷轴20能够转动以释放柔性显示屏组件30，从而扩展柔性显示屏32的显示部分301。具体地，柔性显示屏组件30的一端与第二部分14固定连接，另一端穿过第一部分12的第一开口1222后与设置在容置空间120内的卷轴20连接。
如此，在第一部分12和第二部分14做相离运动时，卷轴20能够转动以释放柔性显示屏组件30，从而扩展柔性显示屏32的显示部分301。如此，可对电子装置100的屏幕显示区域的大小进行自由调节，在需要使用大屏幕时可以扩展柔性显示屏32的显示部分301以提高用户的操作体验，同时，在不需要使用大屏幕时，可以不对显示部分301进行扩展，从而使得整机尺寸较小，方便携带。
可以理解，请参阅图5，在一种情况下，第一部分12和第二部分14靠近连接在一起，在这样的情况下，柔性显示屏32的显示部分301没有被扩展，电子装置100处于窄屏模式，此时，柔性显示屏组件30的一部分卷收在卷轴20上，一部分位于第一顶板122上方且从壳体10露出以用于显示。需要说明的是，在本实施方式中“柔性显示屏32的显示部分301”可以理解为位于第二部分14的第二顶板142上方的部分，即，从壳体10上露出以用于显示的部分。
请参阅图7，在需要扩展柔性显示屏32的显示部分301时，第一部分12和第二部分14做相离运动，这样，第二部分14会带动柔性显示屏组件30的一端运动，此时，卷轴20可释放柔性显示屏组件30的柔性支撑件34，从而使得柔性显示屏32的显示部分301增大，进而提高用户的操作体验以及需求。在这样的情况下，电子装置100处于扩展模式。
可以理解的是，第二部分14和第一部分12两者做相离运动时存在极限位置，在处于极限位置时，电子装置100的显示区域最大，即柔性显示屏32组从壳体10露出的区域最大，也即柔性显示屏32的显示部分301面积最大(如图7所示)。在第一部分12和第二部分14靠近且连接配合在一起时，电子装置100的显示区域最小，即柔性显示屏32的显示部分301最小，也即柔性显示屏32的显示部分301面积最小(如图5所示)。
柔性显示屏组件30的一端固定连接在第二部分14，可以指的是柔性显示组件30的一端直接固定在第二部分14，也可以指柔性显示组件30通过其它介质固定在第二部分14。柔性显示屏组件30的一端与相对于第二部分14无法运动。
本申请的实施方式中，柔性显示屏组件30的一端指的是柔性显示屏组件30的第一边缘，柔性显示屏组件30的另一端指的是柔性显示组件30的第二边缘，第二边缘与第一边缘相对设置。
具体地，请参阅图3、图5和图7，柔性显示屏组件30包括柔性显示屏32和柔性支撑件34，柔性显示屏32与柔性支撑件34层叠设置且固定连接，柔性显示屏32连接第二部分14，柔性支撑件34卷绕设置在卷轴20上并与柔性显示屏32固定连接。
具体地，柔性显示屏32包括与第二顶板142固定连接的第一区域322和与第一区域322连接的第二区域324，第一区域322与第二顶板142相对应且贴设在第二顶板142上。
第二区域324至少部分地位于第一部分12的容置空间120内且贴设在柔性支撑件34上。第一区域322可通过光学胶(Optically Clear Adhesive，OCA)与第二顶板142固定连接。
柔性支撑件34设置在第二区域324的底部并且完全覆盖第二区域324，柔性支撑件34也可以通过光学胶(Optically Clear Adhesive，OCA)与第二区域324固定连接。在图5和图7所示的示例中，柔性支撑件34包括第一支撑部341和第二支撑部343，第一支撑部341与第二区域324相对应，第二支撑部343卷绕设置在卷轴20上，也即是说，在这样的实施方式中，第二支撑部343超出第二区域324且卷绕设置在卷轴20上。请参阅图5，在电子装置100处于窄屏模式时，柔性支撑件34卷收在卷轴20上，柔性显示屏32大致呈“U”字型。
如此，在电子装置100处于窄屏模式时(即第一部分12和第二部分14做相向运动至极限位置时)，卷轴20卷起的仅仅只是柔性支撑件34的第二支撑部343，而柔性显示屏32不会直接被卷轴20卷起，这样可以减少柔性显示屏32的被弯折程度和次数，提高了柔性显示屏32的使用寿命。当然，可以理解，请参阅图17，在其它实施方式中，柔性显示屏32也可以是与柔性支撑件34与第二区域325相对应，柔性支撑件34与柔性显示屏30共同卷绕设置在卷轴20上，也即是说，卷轴20可将柔性支撑件34和柔性显示屏32两者同时卷起和同时释放，具体设置方式在此不作限制。
此外，在本实施方式中，柔性显示屏组件30大致呈的“U”字型，电子装置100的主板、副板、传感器和电池等电气元件可以收纳在柔性显示屏组件30围成的空间内。这样，柔性显示屏组件30的设置方式不会影响主板和电池等电气元件的摆放，有效的提高了空间的利用率，有利于主板、电池等电气元件的堆叠和摆放。
请参阅图5和图7，在本实施方式中，在第一部分12和第二部分14做相离运动时，柔性支撑件34抵持第一部分12以使柔性显示屏32的扩展部分保持平整。
需要指出的是，上述“扩展部分”可以理解为在第一部分12和第二部分14座相离运动的过程中，从第一部分12中拉出的柔性显示屏组件30的那一部分，即柔性显示屏组件30所增大的显示部分。在下文中，若遇到相同或者类似的描述，也可参此处理解。
具体地，第一顶板122与柔性显示屏32的显示部分301相对设置且与第一顶板122贴合，在第一部分12和第二部分14相离时，柔性支撑件34位于柔性显示屏32与第一顶板122之间以填充柔性显示屏32与第一顶板122之间的间隙。也即是说，柔性支撑件34的厚度等于第一部分12的上表面与第二部分14的上表面之间的距离。
可以理解，请参阅图7，在第一部分12与第二部分14做相离运动时，第一顶板122的上表面和第二顶板142的上表面之间具有高度差，柔性显示屏32固定连接在第二顶板142的上表面，此时，柔性支撑件34抵持第一部分12的第一顶板122，即并柔性支撑件34填充柔性显示屏32与第一顶板122之间的间隙。也即是说，由于第一顶板122和第二顶板142上下贴合，柔性显示屏32固定连接在第二顶板142的上表面，因此，柔性支撑件34的厚度等于第二顶板142的厚度可以填充第一顶板122和第二顶板142之间的高度差，即填充柔性显示屏32与第一顶板122之间的间隙， 从而能够在柔性显示屏32在运动时使得柔性显示屏32的扩展部分保持平整，从而减少在电子装置100处于扩展模式时柔性显示屏32在被触摸时出现按压变形、塌陷以及错动现象，提高用户的操作体验。此外，柔性支撑件34与柔性显示屏32层叠设置，在扩展柔性显示屏32的显示区域301是，柔性支撑件34也会跟随柔性显示屏32运动，这样可以使得柔性支撑件34的支撑面积较大，从而可进一步放置减小柔性显示屏32出现按压变形等现象。
此外，请继续参阅图3、图5和图7，柔性支撑件34的底部形成有第一齿部342，第一齿部342用于与限位件40啮合以使得在限位件40能够支撑柔性显示屏组件30并保持柔性显示屏组件30能够平稳运动。
另外，在本实施方式中，柔性支撑件34可由磁性材料制成，柔性支撑件34能够吸附在第一顶板122上。具体地，在图5和图7所示的实施方式中，第一顶板122也可由磁性材料制成。这样，柔性支撑件34与第一顶板122可以相互吸引，在第二部分14相对于第一部分12做相离运动以扩展柔性显示屏32的显示部分301时，柔性支撑件34可以吸附在第一顶板122上。可以理解的是，在这样的实施方式中，柔性支撑件34和第一顶板122的其中一个具有永磁性，另外一个也可具备永磁性或者不具备永磁性。
此外，在一些实施方式中，第一顶板122可包括支撑层(图未示)和设置在支撑层上的磁性层(图未示)在第二部分14相对于第一部分12做相离运动以扩展柔性显示屏32的显示部分301时，柔性支撑件34能够吸附在磁性层上，这样同样也可以进一步减少在操作时柔性显示屏组件30出现错位或者窜动的现象以提高用户的操作体验，同时，在这样的实施方式中，可以不需要整个第一顶板122都由磁性材料制成，而只要磁性层由磁性材料制成即可，从而节约了制造成本。可以理解的是，在这样的实施方式中，柔性支撑件34和磁性层的其中一个具有永磁性，另外一个也可具备永磁性或者不具备永磁性，具体不作限制。
请参阅图5、图7和图8，限位件40转动设置在第一部分12的容置空间120内且从第一开口1222露出，柔性显示屏组件30的中间部分绕设在限位件40上。限位件40呈柱状，限位件40的圆周上形成有第二齿部42，第二齿部42用于与柔性支撑件34上的第一齿部342啮合以对柔性显示屏组件30进行支撑和对柔性显示屏组件30的扩展进行导向。可以理解，柔性显示屏组件30的中间部分可以理解为位于柔性显示屏组件30的两端之间的部位。
如此，限位件40可以限制柔性显示组件30的形态，以使柔性显示组件30的显示部分301可以呈平整的状态，即可以使得柔性显示屏组件30保持处于U型状态。另外，限位件40与柔性支撑件34啮合既可以对柔性显示屏组件30进行支撑，又可以在第二部分14带动柔性显示屏组件30运动时进行导向以保持柔性显示屏组件30能够的平稳运动。
具体地，在本实施方式中，限位件40为一个导向齿轮，限位件40设置在于第一开口1222对应的位置，柔性显示屏组件30的中间部分绕设在限位件40上，柔性支撑件34上的第一齿部342和第二齿部42啮合。也即是说，柔性显示屏组件30的一端与第二部分14固定连接，另一端穿过第一开口1222并绕过限位件40后与卷轴20连接。在第二部分14带动柔性显示屏32的一端运动时，限位件40在柔性支撑件34的带动下逐渐转动，卷轴20逐渐释放柔性支撑件34的一端。
可以理解的是，在其它实施方式中，限位件40也可以不形成有第二齿部42，而是直接为光轴或者滚筒，柔性支撑件34也可不形成第一齿部342，限位件40和柔性支撑件34直接滚动连接，柔性显示屏组件30直接绕过滚筒，这样，限位件40同样也能够对柔性显示屏32进行支撑和导向。
请参阅图5、图7和图10，在本实施方式中，摄像头60可设置在第一部分12的容置空间120，盖体50与第一部分12连接并盖设容置空间120，摄像头60能够通过盖体50进行图像采集。也即是说，在本实施方式中，第一部分12与盖体50是形成一个整体，在第二部分14相对于第一部分12运动时，摄像头60不会跟随移动，在处于扩展模式时，摄像头60位于整个柔性显示屏32的中间位置。
在本实施方式中，盖体50与第一部分12可拆卸地连接，如此，可以方便将盖体50拆卸下来对堆叠设置在容置空间120内的主板、电池或者传感器等电气元件进行维修和更换。可以理解，在其它实施方式中，盖体50与第一部分12也可为一体结构，两者一体成型，具体设置方式在此不作限制。
此外，请结合图11和图12，盖体50上可开设有与摄像头60位置相对应的透光部56，光线可 透过透光部56以被摄像头60接收以使摄像头60能够通过盖体50进行图像采集以对外进行拍摄。这样，透光部56可以在不影响摄像头60的拍摄效果的前提下对摄像头60进行保护，从而防止摄像头60直接暴露在壳体10外而导致意外划伤摄像头60。
可以理解的是，请参阅图13和图14，在其它实施方式中，摄像头60也可以是与第二部分14固定连接并通过第二部分14采集图像。具体地，在这样的实施方式中，第二部分14形成有收纳空间140，摄像头60设置在收纳空间140内，光线能够透过第二部分14以被摄像头60接收从而使得摄像头60能够通过第二部分60进行图像采集，在第二部分14相对第一部分12运动时，摄像头60也会跟随第二部分14运动。这样，可以在实现能够调节柔性显示屏组件30的显示区域301的大小的也不会影响摄像头60的拍照和摄像功能，从而用户在任何情况下都可以方便拍照使用。
在这样的实施方式中，第二部分14还包括底板146，底板146和第二顶板142相对设置且限定形成收纳腔室140，也即是说，摄像头60可设置在第二顶板142和底板146之间的收纳腔室140内，即摄像头30可通过第二部分14的底板146进行图像采集。当然，可以理解的是，摄像头60也可以只是部分位于收纳腔室140内，只要能够实现摄像头60的正常拍摄和拍照功能即可，具体在此不作限制。
进一步地，在这样的实施方式中，为了使得摄像头60能够正常拍照和拍摄，底板146上可开设有与摄像头60相对应的通孔或者底板146包括与摄像头60相对应的透光区域，摄像头60从通孔露出或者是通过透光区域采集图像，即光线可穿过通孔或者透过透光区域以被摄像头60接收，透光区域可采用玻璃等透光材料制成。
此外，请参阅图15和图16，在这样的实施方式中，盖体50包括第一连接部52和第二连接部54，第一连接部52固定连接在第一部分12的底部并封闭容置空间120，第二连接部54固定连接在第二部分14的底部，摄像头60能够通过第二连接部54采集图像。也即是说，第二连接部54与第一部分12固定连接，第二连接部54与第二部分14固定连接，第二连接部54可相对于第一连接部52分运动，摄像头60能够跟随第二部分14运动。
具体地，第二连接部52可固定或者可拆卸地连接在底板146的底板，第二连接部52包括与通孔或者透光区域对应的透光部56，也即是说，摄像头60、通孔(或者透光区域)以及透光部56三者是相对应的。这样，摄像头60可以通过通孔(或者透光区域)以及透光部56接收光线以进行图像采集。
请参阅图13和图15，在电子装置100处于窄屏模式，即第一部分12和第二部分14相向运动至极限位置时，第一连接部52和第二连接部54拼接以共同形成电子装置100的盖体50。请参阅图14和图16，在第二部分14相对第一部分12做相离运动时，第二连接部54与第二连接部52分离。
具体地，请结合图13和图14，在这样的实施方式中，第一连接部52上形成有呈弧形的凹部542，第二连接部54上形成有与凹部542相匹配的凸部522，凸部522也呈弧形在电子装置100处于窄屏模式时(如图13和图15所示)，凹部542与凸部522拼接在一起以实现第一连接部52和第二连接部54的拼接。可以理解的是，第一连接部52和第二连接部54也可以制作成其它形态，例如，两者都呈矩形状，两者可直接拼接成盖体50，再例如，两者的其中一个上可形成有规则排列的凸起，在另一个上形成有与凸起对应的凹槽，这样，在电子装置100处于扩展模式时可以丰富壳体10的形态以提高美感。
进一步地，在这样的实施方式中，第一连接部52和第二连接部54可设计成两种不同的颜色效果，这样可以丰富电子装置100的外观效果。
请参阅图3、图5和图7，在本实施方式中，驱动机构70可设置在第一部分12的容置空间120内，驱动机构70与第二部分14连接，驱动机构70用于驱动第二部分14相对于第一部分12做相离运动以带动柔性显示屏组件30伸展。
此外，请参阅图5和图7，在实施方式中，驱动机构70还可与卷轴20连接，在驱动机构70驱动第二部分14相对于第一部分12做相离运动时，驱动机构70还可同时驱动卷轴20转动以释放柔性显示屏组件30，从而扩展柔性显示屏组件30的显示部分301。
具体地，驱动机构70可包括电机71、第一传动结构72和第二传动结构74，电机71可固定设置在第一部分12的容置空间120内。第一传动结构72和第二部分14以及电机71连接，第二传动结构74与第一传动结构74以及卷轴20连接，电机71用于通过第一传动结构72驱动第二部分14 相对于第一部分12运动以及通过第一传动结构72和第二传动结构74驱动卷轴20转动。
第一传动结构72包括第一传动齿轮722和齿条724。第一传动齿轮722与第二传动结构74连接且固定在电机71的电机轴711上，齿条724与第二部分14固定连接，齿条724与第一传动齿轮722啮合。如此，本实施方式中采用齿轮和齿条驱动进行驱动，其结构简单且传动较为平稳和可靠。
具体地，在本实施方式中，齿条724与第二部分14的第二顶板142一体成型，也即是说，齿条724可以直接一体成型在第二顶板142的下表面，这样，齿条724可直接第二顶板142上加工形成，其整体性较好，加工方便。可以理解的是，在其它实施方式中，齿条724也可以是与第二部分14分体成型，然后两者通过焊接等方式固定连接在一起，具体在此不作限制。
请再次参阅图5和图7，第二传动结构74连接卷轴20和第一传动齿轮722。第二传动结构74包括第二传动齿轮742和第三传动齿轮744，第二传动齿轮742固定在卷轴20上且与卷轴20同心设置，第三传动齿轮744转动设置在第一部分12上，并且第三传动齿轮744连接第二传动齿轮742和第一传动齿轮722，即第三传动齿轮744分别与第二传动齿轮742和第一传动齿轮722啮合，第一传动齿轮722和第二传动齿轮742位于第三传动齿轮744的相反两侧。
在本实施方式中，电机71可用于通过第一传动结构72驱动第二部14相对于第一部分12运动。同时，电机71也可用于在驱动第二部分14相对于第一部分12做相离运动的同时，通过第二传动结构74驱动卷轴20转动以释放柔性显示屏组件30。如此，柔性显示屏组件30的伸展和卷轴20的同步释放使得运动较为平稳，柔性显示屏组件30不易出现褶皱。
具体地，在需要对扩展电子装置100的显示区域，即扩展柔性显示屏组件30的显示部分301时，可通过电机71带动第一传动齿轮722转动，第一传动齿轮722通过齿条724驱动第二部分14相对于第一部分12做相离运动，第二部分14带动柔性显示屏组件30的伸展，即带动柔性显示屏组件30的一端相对于第一部分12做相离运动，与此同时，第一传动齿轮722也可同时带动第三传动齿轮744转动，第三传动齿轮744带动卷轴20转动，从而使得卷轴20能够同步释放柔性显示屏组件30，进而达到扩展柔性显示屏组件30的显示部分301的目的。
可以理解，在需要缩小柔性显示屏组件30的显示部分301时，只需要使得电机71反转，从而带动第二部分14相对于第一部分12做相向运动即可，在这样的情况下，第二部分14逐渐释放柔性显示屏组件30，卷轴20也能够逐渐将柔性显示屏组件30卷起。可以理解的是，在本实施方式中，在单位时间内，第二部分14的运动行程与卷轴20转动所释放的柔性显示屏组件30的长度是相等的。也即是说，在第二部分14拉动柔性显示屏组件30的一端运动多少距离，卷轴20就转动以释放多少长度，这样可以保证柔性显示屏组件30能够平稳的运动而不会出现褶皱。
此外，还可以理解的是，在某些实施方式中，为了保证卷轴20卷起和释放柔性显示屏组件30的平稳性，驱动机构70的数量可为两个，卷轴20的数量也为两个，两个驱动机构70可沿电子装置100的纵向方向对称设置在容置空间120内且分别与第二部分14连接，并且也分别与两个卷轴20连接。这样，可通过两个相同的驱动机构70同步驱动来实现两个卷轴20的同步且平稳转动以及第二部分14的平稳移动，从而保证电子装置100在扩展柔性显示屏32的显示部分301时的运动的可靠性。
再有，在其它一些实施方式中，驱动机构70也可以包括设置在第一部分12上的两个同步电机，其中一个电机用于驱动第二部分14相对第一部分12运动，另外一个电机驱动卷轴20转动，两者采用单独的电机进行驱动。这样，两个电机同步运动，同样也能够保证柔性显示屏组件30运动的平稳性以及运动的可靠性。
另外，请参阅图17，在某些实施方式中，驱动机构70也可只括设置在第一部分12上的电机以及与电机连接的第一传动结构72，电机可通过第一传动结构72带动第二部分14相对于第一部分12运动。
进一步地，请参阅图18-图21，在这样的实施方式中，电子装置100还可包括回复机构80，回复机构80也可设置容置空间120内，回复机构80连接卷轴20，回复机构20用于给柔性显示屏组件30施加回复力以使柔性支撑件34保持卷绕设置在卷轴20上的趋势。
具体地，回复机构80给卷轴20施加回复力，卷轴20在回复力的作用下使得柔性显示屏组件30保持卷收在卷轴20上的趋势。也即是说，在第二部分14没有受到外力的作用相对于第一部分12运动时，回复机构80的回复力会使得卷轴20转动，从而使得柔性显示屏组件30的一端卷收在 卷轴20上，在这样的情况下，第一部分12与第二部分14完全配合在一起，电子装置100处于窄屏模式。
在第二部分14受到外力作用且外力大于或等于回复机构80的回复力时，第二部分14会相对于第一部分12做相离运动，从而带动卷轴20克服回复力进行转动以释放柔性显示屏组件30的柔性支撑件34，从而扩展柔性显示屏32的显示部分301。
可以理解的是，由于回复机构80的存在，在扩展柔性显示屏32的显示部分301过程中，回复机构80一直会会给柔性显示屏组件30施加张力，从而使得柔性显示屏能够收放平衡，即使得柔性显示屏组件30一直保持平整。
还可以理解的是，在其它实施方式中，在电子装置100包括回复机构80的情况下，驱动机构70也可包括上述实施方式中的电机、第一传动结构72和第二传动结构74，第一传动结构72连接电机的第二部分12，第二传动结构74连接第一传动结构72和卷轴20。在这样的实施方式中，在需要缩减显示区域301时，电机可不工作，而是利用回复机构80的回复力带动卷轴20反转以卷收柔性显示屏组件30并且带动第二部分14相对于第一部分12做相向运动，即靠近第一部分12。
进一步地，请参阅图19，回复机构80可包括弹性元件，弹性元件与卷轴20连接且用于给卷轴20施加回复力。弹性元件可为弹簧，例如如图19所示的扭簧等。当然弹性元件也可以为橡胶等具有弹性回复力的元件，具体在此不作限制。
在进一步地，请参阅图20，在这样的实施方式中，电子装置100还可包括卡位结构90，卡位结构90设置壳体10上，卡位结构90用于在第二部分14相对于第一部分12运动至预定位置时限制卷轴20的转动。也即是说，在第二部分14相对于第一部分12运动至预定位置时，卡位结构90可以防止第二部分14和柔性显示屏组件30在回复机构80的回复力的作用下回缩。
具体地，请参阅图20，在本实施方式中，卡位结构90可包括形成在第一部分12的卡块92和形成在第二部分14的卡槽94，在第二部分14相对于第一部分12运动至预定位置时，卡块92卡合在卡槽94中。这样，即使撤销对第二部分14外力，由于卡块92和卡槽94卡合，第二部分14和柔性显示屏组件30也不会在回复机构80的回复力的作用下回缩。以保证电子装置100处于扩展模式。
需要说明的是，上述“预设位置”可以是至第二部分14相对第一部分12做相离运动至极限位置时两者的相对位置，也可以是极限位置之前的任意位置。
可以理解的是，请参阅图21，在其它实施方式中，也可以是在第一部分12形成卡槽94，第二部14形成卡块92。此外，在一些实施方式中，也可是在第一部分12形成卡块，在卷轴20上形成卡槽，在第二部分14运动至预设位置时，卡块和卡槽卡合，在这样的情况下，可通过手动按压的方式或者电驱动的方式使得卡块和卡槽卡合，从而使得卷轴不会相对第一部分转动，进而使得第二部分14和柔性显示屏组件30不会在回复机构80的作用下回缩。当然，在另外一些实施方式中，卡位结构90也可包括卡件，回复机构80包括扭簧，在第二部分14运动至预设位置时，卡件可以卡住扭簧以抵消扭簧的回复力。另外，还可以理解的是，在一些实施方式中，卡位结构90也可包括设置在第一部分12的弹性组件以及形成在第二部分14上的第一卡扣部，弹性组件可包括按压件、弹簧和第二卡扣部，按压件安装在第一部分12，弹簧连接按压件和第二卡扣部，按压件可用于在外力的作用下通过弹簧驱动第二卡扣部运动以与的第一卡扣部扣合，从而限定所述第一部分12和第二部分14的相对位置。这样，在第二部分14运动到预设位置时，用户可通过按压按压件从而使得第一卡扣部和第二卡扣部卡合从而防止第二部分14在回复机构80的回复力的作用下回缩，使电子装置100保持处于扩展模式。可以理解的是，在再次按压按压件时，第一卡扣部和第二卡扣部分离，从而使得第二部分14和柔性显示屏组件30能够在回复机构80的作用下回缩，以使电子装置100从扩展模式回归至窄屏模式。
请参阅图4至图7，下面对本实施方式的电子装置100工作原理进行介绍。
正如上述，电子装置100能够在窄屏模式和扩展模式之间切换。在图4和图5所示的状态中，电子装置100处于窄屏模式，在图6和图7所示的状态中，电子装置100处于扩展模式。在处于窄屏模式时，第一部分12和第二部分14相互配合以形成壳体10，柔性显示屏组件30的一端卷收在卷轴20上，另一端连接第二部分14，此时，柔性显示屏组件30只有较小的部分从壳体10露出，显示部分301较窄，这样可方便用户携带。
在用户需要较大的显示部分301时，可通过驱动机构70驱动第二部分14相对于第一部分12做相离运动，此时，第二部分14带动柔性显示屏32的一端运动，同时驱动机构70也带动卷轴20转动并释放柔性显示屏组件30的柔性支撑件34，这样，柔性显示屏组件30的隐藏在壳体10内部分逐渐被第二部分14拉出(即从图4所示的状态运动至图6所示的状态)，从而达到扩展柔性显示屏32的显示部分301的目的，此时，显示部分301的区域较大，可以方便用户操作以提高用户的操作体验。
在需要从扩展模式切换至窄屏模式时，只需要使得驱动机构70的电机反转即可带动第二部分14相对于第一部分12做相向运动，从而释放柔性显示屏组件30，此时，卷轴20也相应反转，同步将柔性显示屏组件30卷起，在运动至第一部分12和第二部分14之间的相向运动的极限位置时，电机停止运行，电子装置100回归至窄屏模式。
综合上述，本申请实施方式的电子装置100包括壳体10、卷轴20和柔性显示屏组件30。壳体10包括能够相对运动的第一部分12和第二部分14。卷轴20设置在第一部分12。柔性显示屏组件30包括柔性显示屏32和与柔性显示屏32层叠设置且固定连接的柔性支撑件34，柔性显示屏32连接第二部分14，柔性支撑件34卷绕设置在卷轴20上并固定连接柔性显示屏32，在第一部分12和第二部分14做相离运动时，卷轴20能够转动以释放柔性显示屏组件30的柔性支撑件34，从而扩展柔性显示屏32的显示部分301。其中，在第一部分12和第二部分14做相离运动时，柔性支撑件34抵持在第一部分12以使柔性显示屏32的扩展部分保持平整。
目前，用户对移动终端使用越来越频繁，使用场景日趋多样化。目前大部分便携式智能移动终端屏幕尺寸较小，通常在7英寸以下，与平板等产品相比，屏幕显示区域有限，用户操作体验受限。然而，屏幕尺寸较大的移动终端，例如大于7英寸的移动终端，虽然屏幕尺寸增大，但是整机尺寸较大，不方便携带。
在相关技术中，通过设计卷轴式柔性屏移动端来实现对显示区域的大小的调节。因此，在实现屏幕大小可调节的同时，如何对屏幕伸出部分的进行支撑以防止屏幕出现按压变形以及错动成为了亟待解决的技术问题。
在本申请实施方式的电子装置100中，在第一部分12和第二部分14做相离运动以扩展柔性显示屏32的显示部分时，柔性支撑件34可以抵持在第一部分12以使柔性显示屏32的扩展部分保持平整。这样，柔性支撑件34可以抵持在第一部分12，从而减少柔性显示屏32出现按压变形、塌陷以及错动的现象，以提高用户的操作体验。
在本说明书的描述中，参考术语“某些实施方式”、“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
