请结合图1至图3，本实施方式的电子设备100包括壳组件10、柔性显示屏30、带动件50及驱动机构70。壳组件10为中空结构。带动件50、驱动机构70以及摄像头90等组件均可设置在壳组件10。可以理解的是，本申请实施方式的电子设备100包括但不限于手机、平板电脑等移动终端或其它便携式设备。在本文中，以电子设备100以手机为例进行说明。
在本实施方式中，壳组件10包括第一壳体12和第二壳体14，第一壳体12和第二壳体14能够相对运动。在本实施方式中，第一壳体12和第二壳体14滑动连接，也即是说，第二壳体14能够相对第一壳体12滑动。例如，第一壳体12和第二壳体14中的一者可以设有滑轨，另一者可沿滑轨滑动。
请参阅图4及图5，第一壳体12与第二壳体14共同形成有容置空间16。容置空间16可用于放置带动件50、摄像头60及驱动机构70等部件。壳组件10还可包括后盖18，后盖18与第一壳体12与第二壳体14共同形成容置空间16。
带动件50设置于第二壳体14，柔性显示屏30的一端设置于第一壳体12，柔性显示屏30绕过带动件50，且柔性显示屏的另一端设置于容置空间16内，以使部分柔性显示屏隐藏于容置空间16内，隐藏于容置空间16内的部分柔性显示屏30可不点亮。如图5所示，第一壳体12和第二壳体14相对远离，可通过带动件50带动柔性显示屏30展开，以使得更多的柔性显示屏30暴露于容置空间16外。点亮暴露于容置空间16外部的柔性显示屏30，以使得电子设备100所呈现的显示区域变大。例如，从图1至图2可以看出电子设备的柔性显示屏30从收缩状态到伸展状态的形态变化对比。
请再次参阅图4及图5，带动件50可为外部带有齿52的转轴结构，柔性显示屏30通过啮合等方式与带动件50相联动，第一壳体12和第二壳体14相对远 离时，通过带动件50带动啮合于带动件50上的部分柔性显示屏30移动并展开。
可以理解的是，带动件50还可为不附带齿52的圆轴，第一壳体12和第二壳体14相对远离时，通过带动件50将卷绕于带动件50上的部分柔性显示屏30撑开，以使更多的柔性显示屏暴露于容置空间16外，并处于平展状态。具体的，带动件50可转动地设置于第二壳体14，在逐步撑开柔性显示屏30时，带动件50可随柔性显示屏30的移动而转动。
在其它实施方式中，带动件50也可固定在第二壳体14上，带动件50具备光滑的表面。在将柔性显示屏30撑开时，带动件50通过其光滑的表面与柔性显示屏30可滑动接触。可以理解的是，带动件50也可以省略，第二壳体14远离第一壳体12的一端可为光滑表面，以实现对柔性显示屏30的带动作用。
当第一壳体12和第二壳体14相对靠近时，柔性显示屏可通过带动件50带动收回。或者，电子设备100还包括复位件(图未示)，柔性显示屏收容于容置空间16的一端与复位件联动，在第一壳体12和第二壳体14相对靠近时，复位件带动柔性显示屏30复位，进而使得部分柔性显示屏收回于容置空间16内。
在本实施方式中，驱动机构70可设置在容置空间16内，驱动机构70可与第二壳体14相联动，驱动机构70用于驱动第二壳体14相对于第一壳体12做相离运动，进而带动柔性显示屏组件30伸展。可以理解的是，驱动机构70也可以省略，用户可以直接通过手动等方式来使得第一壳体12和第二壳体14相对运动。
需要说明的是，除了按照图1至图5的硬件排布设计使柔性显示屏30可以在电子设备的横向方向上进行伸缩(例如在左右方向上进行的伸缩)外，在其它一些实施方式中，还可以改变结构和硬件排布设计的方向使得柔性显示屏30可以在电子设备的纵向方向上进行伸缩(例如在上下方向上进行的伸缩)。
请一并参阅图6及图7，图6为第二壳体14相对第一壳体12滑动至第一位置时的结构示意图，图7为第二壳体14相对第一壳体12滑动至第二位置时的结构示意图。当第二壳体14相对第一壳体12滑动到第一位置时，电子设备100可以获得相对较大的显示面积，以提升电子设备100的使用体验。而第二壳体14相对第一壳体12滑动到第二位置时，电子设备100具有相对较小的外形尺寸，便于携带。
为了使电子设备100在使用时保持较大的显示面积，在本申请实施例中，电子设备100还包括用于使得第一壳体12与第二壳体14之间相互定位的锁止装置20。锁止装置20包括第一支架210、第二支架230、连杆机构250及定位机构270。
第一支架210设置于第一壳体12上，第二支架230设置于第二壳体14上。第一支架210及第二支架230可随第一壳体12或第二壳体14的运动而靠近或远离。连杆机构250连接于第一支架210和第二支架230之间，连杆机构250能够随第一壳体12与第二壳体14间的距离改变而收缩或拉伸。
定位机构270连接于第二支架230。请再次参阅图6，连杆机构250处于拉 伸状态时，连杆机构250能够与定位机构270相抵持。由于连杆机构250与定位机构270相抵持状态，使得连接在第一支架210以及第二支架230之间的连杆机构250被锁止，进而以使第一壳体12与第二壳体14的位置相对固定，电子设备100可以保持拉伸状态，在使用时，第一壳体12或者第二壳体14不会因为外力影响而缩回，保证了在使用时电子设备100的尺寸固定。
由于第二壳体14能够相对第一壳体12滑动，以带动至少部分柔性显示屏30进出第一壳体12或第二壳体14，从而改变用户所能看到的显示区域的大小，并在进出过程中带动连杆机构250收缩或拉伸。连杆机构250与定位机构270相抵持，以使柔性显示屏30相对第一壳体12或第二壳体14固定，进而使得电子设备100保持拉伸状态，显示区域大小不会因为外力的影响意外改变，进而提升了用户体验。
可以理解的是，在本实施例中，第一位置、第二位置可以视为第二壳体14相对第一壳体12运动的两个极限位置。在第一位置时，暴露在壳组件10外的柔性显示屏30的显示面积达到最大状态，在正常情况下，第二壳体14不能再相对第一壳体12做相对远离运动。第一位置可以通过在锁止装置20的锁止来保持。在第二位置时，柔性显示屏30收入壳组件10中，显示面积达到最小状态，在正常情况下，第二壳体14不能再相对第一壳体12做相向靠近运动。
请一并参阅图8，在本实施例中，连杆机构250包括第一连杆252、第二连杆254及抵持件256。第一连杆252的两端分别可转动地连接于第一支架210及抵持件256，第二连杆254的两端分别可转动地连接于第二支架230及抵持件256。
设定第一壳体12及第二壳体14相对运动的方向为第一方向。第一支架210与第二支架230随第一壳体12及第二壳体14在第一方向上相互靠近或远离，以通过第一连杆252及第二连杆254带动抵持件256运动。
抵持件256随第一连杆252及第二连杆254的摆动而运动，且抵持件256能够与定位机构270在垂直于第一方向的第二方向相抵持，以使第一支架210与第二支架230的位置相对固定，进而使得第一壳体12与第二壳体14相固定。
连杆机构250还可包括多个第一连杆252及多个第二连杆254，多个第一连杆252间平行设置，多个第二连杆254间平行设置。随着第一壳体12与第二壳体14间的相对运动，多个第一连杆252一同摆动且保持平行，多个第二连杆254一同摆动且保持平行。
连杆机构250具体可为两个，两个连杆机构250分别设置于定位机构270的两侧。在定位机构270的两侧分别设置连杆机构250，可保证第一壳体12与第二壳体14之间滑动时各组件受力均匀，提升滑动的平稳度和流畅度。
在第二壳体14相对第一壳体12拉伸时，两个连杆机构250中的抵持件256可随之相向运动，并分别与定位机构270的两侧相抵持，以使得第一壳体12与第二壳体14间位置相锁定。
可以理解，在满足滑动平稳度和流畅度的前提下，连杆机构250还可为其 它数量，如一个或两个以上，不限于上述的两个。
请再次参阅图6，第一壳体12具有容置腔122，能够容置电池(图未示)或电路板(图未示)等器件。锁止装置20位于容置腔122外，且与第一壳体12及第二壳体14均相连接。锁止装置20连接第一壳体12和第二壳体14且能够引导第二壳体14相对第一壳体12平稳滑动，进而提高第二壳体14与第一壳体12间滑动的稳定性和可靠性。同时，锁止装置20设置在容置腔122外侧，可以避免了占据和隔断容置腔122的空间，有利于电子设备100内部器件的摆放和堆叠。
具体的，容置空间16指的是壳组件10所形成的整体具备容置功能的空间，容置腔122可为容置空间16的一部分。驱动机构70可位于容置腔122中。
请参阅图9，连杆机构250还可包括卡扣258。卡扣258设置于抵持件256的端部。定位机构270还可设有卡槽272，卡扣258与卡槽272相卡接，以使抵持件256与定位机构270相抵持。
具体在本实施例中，请一并参阅图9和图10，其中图10为图9中A处的局部放大图，卡槽272大体可为“C”字形结构。卡槽272的槽壁可包括顶壁272a以及位于顶壁272a两侧的侧壁272b。卡扣258可具体为弹性卡扣258，弹性卡扣258的端面与顶壁272a在第二方向上相抵持。
定位机构270能够相对弹性卡扣258在第一方向上运动，以挤压弹性卡扣258并使弹性卡扣258脱出卡槽272。
具体的，请一并参阅图11和图12，其中，图12为图11中锁止装置20在I-I’处的截面图，定位机构270能够相对弹性卡扣258运动，使得定位机构270挤压弹性卡扣258，弹性卡扣258受到定位机构270的作用力而缩进。请一并参阅图13及图14，其中，图14为图13中锁止装置20在II-II’处的截面图，在定位机构270的作用力的情况下，弹性卡扣258脱出卡槽272，弹性卡扣258的端面与顶壁272a在第二方向上不再相抵持，进而使得连杆机构250与定位机构270之间相解锁，第一壳体12与第二壳体14之间进而可恢复相对运动关系，第二壳体14可相对第一壳体12缩入，进而减小整个电子设备100的体积，便于用户携带。
请一并参阅图15及图16，其中，图16为图15中锁止装置20在III-III’处的截面图，在电子设备100拉伸时，定位机构270可通过其侧壁挤压弹性卡扣258，以使得弹性卡扣258缩入。随着第一壳体12与第二壳体14之间的继续拉伸，弹性卡扣258进入卡槽272位置并弹出，进而与卡槽272相卡接，以使抵持件256与定位机构270相抵持，以再次锁定第一壳体12与第二壳体14间的相对位置，保持电子设备100的展开状态。
弹性卡扣258或卡槽272的侧壁272b可以为楔形结构，以使便于弹性卡扣258与卡槽272之间因挤压而解锁。此外，定位机构270的侧壁为楔形结构，在电子设备100拉伸时，定位机构270通过其楔形结构的侧壁挤压弹性卡扣258，以使得弹性卡扣258更容易因为定位机构270的压力而缩入，待弹性卡扣258进入卡槽272位置时，弹性卡扣258重新弹出并与卡槽272相卡接，以使抵持件256 与定位机构270相抵持，进而再次锁定第一壳体12与第二壳体14间的相对位置。
可以理解，若弹性卡扣258或定位机构270之间相互接触的表面足够光滑，可使得弹性卡扣258足以流畅地卡入或脱出于卡槽272，则弹性卡扣258、卡槽272的侧壁272b以及定位机构270的侧壁还可以为其它形状，不限于楔形。
具体的，请再次参阅图15，定位机构270还可包括驱动件274以及锁止件276。驱动件274连接于第二支架230，锁止件276设置于驱动件274。驱动件274可与驱动机构70相联动，驱动机构70可通过驱动件274来驱使第二壳体14相对第一壳体12运动，进而使得电子设备100能够拉伸或收缩。
卡槽272可设于锁止件276。具体在本实施例中，锁止件276与驱动件274大体可成十字形连接关系，锁止件276可与两侧的连杆机构250相抵持，以使得第二壳体14相对第一壳体12锁止。可以理解，锁止件276与驱动件274间不限于十字形连接，两者之间的连接关系具体由连杆机构250的数量、位置、形状等因素决定。
驱动件274的一端可与第二支架230滑动连接，以使定位机构270相对第二支架230可滑动。定位机构270相对第二支架230可滑动，进而使得第二壳体14在与第一壳体12间锁止时，定位机构270仍然能够相对弹性卡扣258运动，进而挤压弹性卡扣258，使得弹性卡扣258脱出卡槽272，完成第一壳体12与第二壳体14间的解锁，使第一壳体12与第二壳体14间恢复可相对运动状态。
具体在本实施例中，请一并参阅图17，图17为图15中电子设备100在B处的局部放大图。第二支架230可设有限位槽232，驱动件274的一端可滑动地设于限位槽232中，且由限位槽232两侧的槽壁232a限位。驱动件274的一端可滑动地设于限位槽232中，使得驱动件274相对第二壳体14可运动。限位槽232可延第一方向延伸，以使驱动件274可延第一方向与第二支架230滑动连接。
在锁止状态下，电子设备100需要收缩时，驱动机构70可带动驱动件274运动，由于驱动件274相对第二壳体14仍可运动，并未随第二壳体14一同被锁止，故驱动件274可移动并驱使弹性卡扣258脱出卡槽272，完成第一壳体12与第二壳体14间的解锁。驱动件274同时又被限位槽232的槽壁232a限位，使得解锁后，驱动件274可在驱动机构70的驱动下进一步拉动第二壳体14朝向第一壳体12运动，进而实现电子设备100的收缩。
具体的，第二支架230可包括主架体234及滑动连接部236，滑动连接部236连接于主架体234上。具体在本实施例中，滑动连接部236与主架体234间大体可成“T”字形连接。限位槽232可开设于滑动连接部236，驱动件274的一端可滑动地设于限位槽232中，以与滑动连接部236滑动连接。
进一步的，滑动连接部236的两侧均设有限位槽232，驱动件274包括主体部274a以及位于主体部274a一端的两个卡勾部274b，两个卡勾部274b分别可滑动地设于两个限位槽232中。通过两个卡勾部274b，可保证驱动件274与第二支架230间紧密连接，且能够保证驱动件274对第二支架230在拉拽或推动时保持平稳。
以下说明本实施例所提供的电子设备100的具体运作原理：
当需要将电子设备100展开时，驱动件274推动第二支架230，以使第二壳体14相对第一壳体12在第一方向上展开，柔性显示屏30从电子设备100内部释放出，以扩大展示给用户的显示面积。随着电子设备100的展开，连杆机构250也随之展开，由于第一连杆252和第二连杆254的摆动，抵持件256随第一连杆252和第二连杆254向第二方向运动，且结合连杆机构250的展开运动，以使抵持件256运动轨迹形成一个弧形。当电子设备100展开至最大的极限位置，即第一位置时，第二壳体14相对第一壳体12在第一方向无法再展开，整个电子设备100的尺寸固定，此时抵持件256上的弹性卡扣258卡入定位机构270中的卡槽272中，且通过弹性卡扣258的端面与顶壁272a在第二方向上相抵持，进而保持第一壳体12与第二壳体14之间的位置固定。
由于弹性卡扣258的端面与顶壁272a在第二方向上相抵持，使得第一壳体12与第二壳体14之间的位置被锁定，遇到外力时，第二壳体14也不会因外力而向第一壳体12缩进，进而保证了电子设备100展开的固定尺寸，保证了用户体验。
当需要电子设备100收缩为较小尺寸时，驱动件274在驱动机构70的驱动下运动，进而带动定位机构270能够相对弹性卡扣258在第一方向上运动。定位机构270挤压弹性卡扣258并使弹性卡扣258脱出卡槽272，以使整个连杆机构250与定位机构270之间解锁，第一壳体12与第二壳体14之间恢复可运动状态。驱动件274继续运动，进而拉动第二壳体14相对第一壳体12运动，从而带动整个电子设备100收缩，可一直收缩至第二位置。电子设备100收缩后变为较小尺寸，方便用户携带。
请再次参阅图9，第一支架210上还可开设有滑动槽210a。驱动件274远离第二支架230的一端滑动配合于滑动槽210a。通过驱动件274与卡槽272的配合，使得驱动件274能够相对第一支架210移动。
第一支架210具体可包括本体212和挡板214。挡板214可拆卸地连接于本体212并与本体212共同形成滑动槽210a。
驱动件274还可设有限位筋(图未示)，限位筋可以视为驱动件274的一部分。驱动件274的除限位筋以外的部分可以形成平整的表面，限位筋凸出于该平整表面。限位筋能够与第一支架210相抵持，以限制驱动件274相对第一支架210的移动范围。
具体的，限位筋可设置于驱动件274的远离第二支架230的一端。在第二壳体14相对第一壳体12移动至第一位置时，限位筋抵接于第一支架210，进而限定了驱动件274的移动范围，也限定了第二壳体14的移动范围。
请参阅图18，在本实施例中，卡扣258具体还为电动卡扣258a，定位机构270设有至少两个卡槽272，电动卡扣258a择一与至少两个卡槽272相卡接，以使抵持件256与定位机构270相抵持。通过电动的方式，使得卡扣258可自动弹出或缩进。在电子设备100需要锁止时，电动卡扣258a在运动到卡槽272处后 自动弹出，进而使得电动卡扣258a与卡槽272相卡合，电动卡扣258a能够在第二方向上与卡槽272的槽壁抵持，以限定第一壳体12与第二壳体14之间的相对位置，避免电子设备100因外力而收缩或展开。当需要解锁电子设备100时，电动卡扣258a自动缩进，进而使得电动卡扣258a从卡槽272中脱出，第二壳体14与第一壳体12之间再次恢复可相对运动，电子设备100可自由收缩或展开。
在本实施例中，通过定位机构270设有至少两个卡槽272，电动卡扣258a择一与至少两个卡槽272相卡接，以使抵持件256与定位机构270相抵持，进而使得第一壳体12与第二壳体14能在多个位置都相对定位，以实现在上述的第一位置和第二位置之间设置多个中间位置，第二壳体14能够相对第一壳体12在多个中间位置的定位，并使得柔性显示屏30在不同的中间位置具有不同的显示面积，从而拓展电子设备100的使用场景。
可以理解，当卡扣258具体为电动卡扣258a时，驱动件274与第二支架230间可为固定连接，无需通过滑动连接以使卡扣258解锁。
此外，在本申请另一实施例中，上述电子设备100中的第一支架210和第二支架230可以省去，连杆机构250可直接连接于第一壳体12和第二壳体14之间，定位机构270可直接连接于第二壳体14。连杆机构250能够随第一壳体12与第二壳体14间的距离改变而收缩或拉伸。连杆机构250处于拉伸状态时，连杆机构250能够与定位机构270相抵持，以使第一壳体12与第二壳体14的位置相对固定。
具体的，在连杆机构250中，第一连杆252的一端可直接连接于第一壳体12，第二连杆254的一端可直接连接于第二壳体14。此外，上述定位机构270可与第二壳体14间滑动连接，以保证在第二壳体14与第一壳体12位置锁止时，定位机构270能够滑动并驱使卡扣258解锁。
上述电子设备100及其锁止装置20中，连杆机构250处于拉伸状态时，连杆机构250能够与定位机构270相抵持。由于连杆机构250与定位机构270相抵持状态，使得连接在第一支架210以及第二支架230之间的连杆机构250被锁止，进而以使第一壳体12与第二壳体14的位置相对固定，电子设备100可以保持拉伸状态，在使用时，第一壳体12或者第二壳体14不会因为外力影响而缩回，保证了用户的体验。
需要指出的是，锁止装置20还可用在其它设备上，以用于锁止装置20所在设备的位置锁定或解锁，并不仅限于上述的电子设备100。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围 应以所附权利要求为准。
