下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请涉及一种移动终端的显示装置，显示装置具有伸缩功能。图1和图2表示收拢状态下的显示装置，图3和图4表示展开状态下的显示装置。显示 装置包括支撑组件100和卷筒组件，支撑组件100用于支撑柔性屏50，卷筒组件用于缠绕柔性屏50。图1至图4所示的显示装置中，卷筒组件隐藏在支撑组件100内部。
支撑组件100包括相对设置的第一主体10和第二主体20，连接在第一主体10和第二主体20之间的杆组件30，杆组件30包括至少两个相互铰接的连杆，以形成伸缩架构，以使得第一主体10和第二主体20能够相对收拢或展开。第一主体10用于固定柔性屏50的一端，第二主体20内安装卷筒组件，柔性屏50缠绕在卷筒组件上，收拢状态至展开状态的过程中，柔性屏50被拉开，从卷筒组件上释放。
支撑组件100包括外壳，外壳包覆内部的结构，具体而言，外壳包括位于第一主体10上的第一外壳11和位于第二主体20上的第二外壳21，第二外壳21包括视窗部211。在显示装置处于收拢状态时，透过第二外壳21的视窗部211能够看到柔性屏50显示界面。第一外壳11的端部安装有开关模块按键60及充电接口70。
请参阅图5、图6和图7，所述第一主体10包括基座12、基板14和第一压板16，三者层叠设置，基板14和第一压板16分别设于基座12的两侧。所述第二主体20包括基体22，卷筒组件200安装在基体22上。
第一外壳11包括相对设置的顶面112、底面114、连接在顶面112和底面114之一侧的侧面113、及连接在顶面112、底面114和侧面113之间的前端面115和后端面116。顶面112、底面114及前端面115和后端面116之间形成第一开口。基座12、基板14和第一压板16组装后通过第一开口置入第一外壳11内。第一外壳11的前端面115设有用于容纳开关模块按键60的通孔117，第一外壳11的后端面116设有用于容纳充电接口70的通孔118。具体而言，第一外壳11的顶面112和侧面113之间为圆弧面过渡，第一外壳11的底面114和侧面113之间亦可以设置为圆弧面过渡，一种实施方式中，顶面112、侧面113和底面114也可以共同形成U形架构。
第二外壳21与第一外壳11相似，如图5所示，第二外壳21的顶面、侧面及底面共同围设呈C形架构。第二外壳21的顶面和侧面连接处设有视窗部211。第二外壳21的前端面和后端面可以设置螺丝孔，以通过螺丝穿过螺丝孔锁固至第二主体20的基体22内。

请参阅图8和图10，所述基座12包括相对设置的顶面121和底面122，及与所述底面122相邻的第一侧面123。具体而言，基座12的顶面121用于支撑柔性屏50，第一压板16固定至所述基座12的顶面121，所述柔性屏50夹设于所述第一压板16和所述基座12之间，第一压板16的设置使得显示装置在展开的过程中或收拢的过程中，柔性屏50均能够平衡地贴在基座12的顶面121，保证柔性屏50的平整。当然也可以不设置第一压板16，直接将柔性屏50夹在外壳(即第一外壳11)和基座12的顶面121之间，但这种设计方式，要保证第一外壳11和基座12之间的配合公差。
所述基座12的所述底面122包括第一限位部124和限位槽125，所述第一限位部124呈轴孔状，所述第一导杆126安装至所述限位槽125中。具体而言，限位槽125呈长条形，限位槽125的两个端面均设有收容孔1252、1254，其中一个收容孔1254贯穿基座12的的一端与基座12的外部相通，第一导杆126从基座12的外部穿过收容孔1254，并伸入限位槽125中，进一步地插入另一个收容孔1252中，从而将第一导杆126安装在限位槽125内。收容孔1252为螺纹孔，第一导杆126的一端设有螺纹。所述基座12的所述底面122还设有电路腔127和电池腔128。电路腔127用于容纳电路板。电池腔128用于容纳电池。所述电池腔128位于所述限位槽125远离所述第一侧面123的一侧， 所述电路腔127位于所述电池腔128和所述第一限位部124之间。所述电池腔128和所述电路腔127之间设有卡扣129，所述卡扣129设有第一卡槽1292，所述第一限位部124远离所述第一侧面123的一侧设有第二卡槽1294，所述第一卡槽1292与所述第二卡槽1294相对设置，且用于共同定位所述电路板。

基板14的第二侧面143与基座12的第一侧面123共面。第一侧面123和第二侧面141均呈平面状。基板14与基座12之间通过凸柱与定位孔的配合定位，再通过螺丝固定连接。
所述杆组件30之所述连杆包括第一连杆和第二连杆，所述第一连杆的中心位置和所述第二连杆的中心位置通过连接件形成铰接结构，在所述杆组件30收拢状态下，所述第一连杆和所述第二连杆合拢伸入所述间隙G，且所述连接件收容在所述避让槽144中。一种实施方式中，连接件为螺丝。
请参阅图11、图12、图13及图14，所述第二主体20包括基体22，基体22与基座12相对的侧面上设有开槽221，所述开槽221用于收纳所述杆组件30，所述第二限位部224设于所述开槽221内，所述第二限位部224呈螺孔状，基体22的顶面设有与所述第二限位部224相对的通孔2241，基体22的底面设有收容槽225(参见图13)，所述收容槽225与所述开槽221相通，所述第二导杆226安装至所述收容槽225中。第二导杆226安装至收容槽225的具体结构与第一导杆126安装至限位槽125中的具体结构是相同的。

图15和图16为杆组件30与第一导杆126和第二导杆226配合的示意图。
所述杆组件30包括铰接的第一连杆301和第二连杆302，还包括分别设置在所述杆组件30一对对角位置处的第一固定端31和第二移动端34，及分别设置在所述杆组件30另一对对角位置处的第二固定端33和第一移动端32，所述第一固定端31与所述第一限位部124配合形成转轴结构，所述第二固定端33与所述第二限位部224配合形成转轴结构，所述第一移动端32滑动连接至所述第一导杆126，所述第二移动端34滑动连接至所述第二导杆226。所述杆组件30伸缩的过程中所述第一移动端32和所述第二移动端34分别在所述第一导杆126和所述第二导杆226上滑动，实现所述第一主体10和所述第二主体20之间距离的变化。所述第一移动端32包括固定在第二连杆302一端的滑块321，所述滑块321套设于所述第一导杆126上且二者之间光滑接触，所述杆组件30伸缩的过程中，所述滑块321在所述第一导杆126上滑动。同样，第二移动端34包括固定在第一连杆301一端的滑块341，滑块341光滑套设在第二导杆226上，杆组件30伸缩过程中，滑块341在第二导杆226上滑动。第一连杆301上的滑块341的设置的朝向与第二连杆302上的滑块321的设置的朝向相反。
第一连杆301之远离滑块341的一端设置为第一固定端31，第二连杆302远离滑块321的一端设置为第二固定端33。图17、图18、图19为第一连杆 301与第一主体10和第二主体20配合的示意图，第一主体10和第二主体20相对收拢或展开的过程中，第一连杆301以第一固定端31为中心相对第一主体10转动，同时第二移动端34处的滑块341在第二导杆226上滑动，第一连杆301与第一主体10之间的夹角随着第一主体10和第二主体20之间距离的变化而变化，二者相互收拢过程中，夹角变小，展开的过程中，夹角变大。图20、图21和图22为第二连杆302与第一主体10和第二主体20配合的示意图，第二固定端33通过螺丝安装在第二主体20的基体22上，第一主体10和第二主体20相对收拢或展开的过程中，第一连杆301与第二连杆302的运动同步。
请参阅图23，第一连杆301和第二连杆302处于收缩状态时，第一导杆126与第一连杆301重合，第二导杆226与第二连杆302重合，第一连杆301上的滑块341位于第一导杆126的一端，第二连杆302上的滑块321位于第二导杆226的一端。请参阅图15和图16，第一连杆301和第二连杆302处于展开状态时，第一导杆126位于第一连杆301的外部，第一连杆301上的滑块341位于第一导杆126的另一端。第二导杆226位于第二连杆302的外部，第二连杆上302的滑块321位于第二导杆226的另一端。
本申请之支撑组件包括转动限位结构，通过所述转动限位结构，在展开或收拢的过程中，实现所述第一主体10相对所述第二主体20被定位在不同的位置。
本实施方式中，转动限位结构设置在第一固定端31的位置处，其它实施方式中，转动限位结构也可以设置在第二固定端33的位置处，或者设置在第一连杆和第二连杆交叉铰接的位置处。只要能保证第一连杆和第二连杆在转动的过程中可以被限位，可以被限位在任意位置，也可以被限位在指定的某几个位置，实现显示装置收拢或展开过程中定位。
请参阅图24、图25、图26和图27，所述第一固定端31与所述第一主体10的转动连接处设有转动限位结构。具体而言，所述基板14设有开孔147(请参阅图9和图27)，所述开孔147正对所述第一限位部124，第一限位部124为轴孔结构，基板14上的开孔147与第一限位部124同轴。所述第一固定端31包括分别设置在第一连杆301的两侧且同轴的凸轴311和凸环312，所述凸轴311与所述第一限位部124配合，所述凸环312收容于所述开孔147中，所述凸环312与所述开孔147内壁之间的摩擦力形成所述杆组件30伸缩过程中 的限位。也就是说，在杆组件30伸缩的过程中，第一连杆301以第一固定端31为中心旋转，第一固定端31相对第一主体10原位转动，凸环312在开孔147内转动，凸环312与开孔147的内壁之间形成转动过程中的阻尼，这个阻尼力也就是凸环312和开孔147内壁之间的摩擦力，摩擦力的大小可以抵消卷筒组件200弹簧的回弹力，就可以使得展开的柔性屏50被定位在任意位置。
所述转动限位结构还包括套筒313和紧固件314，所述凸环312设有多个切槽3121，所述切槽3121自所述凸环312之远离第一连杆301的一端向所述第一连杆301的方向延伸，相邻的两个所述切槽3121之间均形成凸片3122，切槽3121的设置，使得凸片3122在径向方向上具有弹性变形的能力。所述套筒313呈锥形外表面，收容于所述凸环312内且贴合至所有的所述凸片3122的内表面，所述紧固件314穿过所述套筒313锁固于第一连杆301，以将所述套筒313固定在所述凸环312内并使所述凸片3122向外膨胀。即通过紧固件314与套筒313的配合，使得套筒313向凸环312内移动(即朝向第一连杆301移动)，由于套筒313呈锥形的外表面，套筒313移动的过程中，推动凸片3122向外扩张，从而增加凸环312与开孔147内壁的摩擦力。
所述套筒313的外表面设有至少一个凸肋3132，所述凸肋3132与所述切槽3121配合，防止所述套筒313相对所述凸环312转动，从而保障套筒313的移动方向。切槽3121的深度(即切槽3121在凸环312轴向方向延伸的尺寸)大于凸肋3132的长度(即凸肋3132在凸环313轴向方向延伸的尺寸)，这样预留出套筒313相对凸环312移动的空间。
所述紧固件314为螺丝，所述紧固件314包括头部3142和螺杆3144，所述第一连杆301设有螺孔，所述螺孔贯通第一连杆301，所述紧固件314的头部3142抵持至所述套筒313远离第一连杆301的端面，所述紧固件314的螺杆3144与所述螺孔配合。本实施方式中，凸轴311为中空的结构，即凸轴311设有在中心孔3112，凸轴311的中心孔3112与第一连杆301上的螺孔相通，且二者的孔径可以相同，这样紧固件314可以锁固在凸轴311的中心孔3112内。
一种实施方式中，凸环312与基板14的开孔147内壁之间可以设置为接地路径的一部分。具体而言，第一连杆301与凸环312均为导电材质，可以为金属材质，凸环312与第一连杆301之间可以通过焊接或粘接的方式固定，也 可以一体成型。基板14亦为导电材质，基板14与第一主体10内的电路板的地电连接，可以通过接地弹片电连接，也可以通过导线实现电连接。这样，通过凸环312与开孔147内壁接触，即可以实现杆组件30的接地。杆组件30及基体22的接地设置，可以减轻金属件对显示装置内电路的电磁的干扰，例如若显示装置内的电路板上设天线模块，金属件对天线模块的收发信号势必会造成干扰，若有上述接地的设置，则会减轻干扰，提升信号收发的品质。

所述第一端盖202设有轴向延伸的穿孔2022，所述穿孔2022供所述轴杆205穿过，穿孔2022为第一端盖202的中心通孔，即第一端盖202的中心为 穿孔的轴心。
所述第一端盖202包括外径依次减少的基底2023、套环2024及套管2025，第一端盖202呈阶梯筒状结构，基底2023在轴向方向的尺寸最小，基底2023盖在卷筒201的一端，所述基底2023之面对所述套环2024的台阶面与所述卷筒201的端面相对，基底2023的外表面与卷筒201的外表面共面。所述套环2024与所述卷筒201的内表面贴合。如图36所示，所述凸块2021设于所述套环2024外围，所述卷筒201设有所述卡槽2011，卡槽2011在卷筒201的端面上形成开口，用于供凸块2021插入其中。如图35所示，所述套环2024之面对所述套管2025的台阶面用于抵接套设于所述套管2025上的所述弹簧204的一端。

请参阅图33和图37，所述第二端盖203设有轴向延伸的穿孔2031，所述穿孔2031供所述轴杆205穿过，所述第二端盖203包括外径依次减小的基底2032、套环2033及套管2034，所述套环2033与所述卷筒201的内表面贴合，形成转轴结构，所述基底2032之面对所述套环2033的台阶面与所述卷筒201的端面相对，基底2032的外径与卷筒201的外径相同，即基底2032的外表面与卷筒201的外表面共面。第一端盖202和第二端盖203安装在卷筒201的两端后，二者的外表面形成一体式的柱面结构。所述套环2033之面对所述套管2034的台阶面用于抵接套设于所述套管2034上的所述弹簧204的一端，所述穿孔2031内侧面包括限位面2035，所述限位面2035与所述轴杆205配合以将所述第二端盖203在圆周方向上固定至所述轴杆205。

安装过程中，先将轴杆205穿过第一端盖202，将弹簧204套轴杆205上，且弹簧204的一端套设在第一端盖202的套管2025上，卷筒201套设在弹簧204的外围，使得卷筒201的一端与第一端盖202结合，第一端盖202的凸块2021卡在卷筒201的卡槽2011中，再将第二端盖203安装在卷筒201的另一 端，安装第二端盖203的过程中，先将第二端盖203上的导向槽2037对准弹簧204的一端，安装过程中，使得弹簧204的一端在导向槽2037内移动，当弹簧204的一端移动至与第二端盖203上的固定孔2036相遇时，弹簧204的一端自动卡处固定孔2036内，从而完成了第二端盖203的组装。
所述支撑组件100包括相对设置的第一安装部222和第二安装部223，所述弹簧204、所述第一端盖202、所述卷筒和所述第二端盖203设于所述第一安装部222和所述第二安装部223之间，所述轴杆205穿过依次穿过所述第一安装部222、所述第一端盖202、所述弹簧204和所述卷筒201及所述第二端盖203，并固定至所述第二安装部223。
请参阅图29、图30和图31，所述轴杆205包括杆件2051和设于所述杆件2051一端的头端2052，所述杆件2051之远离所述头端2052的一端为固定端2053，所述头端2052限位于所述第一安装部222之背离所述第二安装部223的一侧，所述固定端2053与所述第二安装部223固定连接。所述头端2052之背离所述杆件2051的端面设有条形槽20521，用于配合锁紧工具使用。所述固定端2053设有环形槽20531，用于与扣片206配合，实现所述轴杆205轴向方向的定位，以防所述轴杆205从所述支撑组件100上脱落。所述固定端2053设有缺口20532和开槽20533，所述缺口20532和所述开槽20533设置在所述固定端2053径向方向上相背的两侧。所述缺口20532的底面形成第一止位面P1，所述开槽20533的底面形成第二止位面P2，所述第一止位面P1与所述第二止位面P2平行。
所述第二端盖203的轴向延伸的穿孔2031内的限位面2035用于与第二止位面P2配合，以将所述第二端盖203在圆周方向上固定至所述轴杆205。
请参阅图38，所述卷筒组件还包括卡扣207和扣片206。所述卡扣207包括一对扣脚2071，所述一对扣脚2071分别与所述缺口20532和所述开槽20533配合，以实现所述轴杆205圆周方向的定位。所述第二安装部223设有卡扣槽2232和内凹部2233，所述内凹部2233位于所述第二安装部223之远离所述第一安装部222的一侧，所述内凹部2233和所述卡扣槽2232之间设有隔板2234，所述第二安装部223设有沿着所述轴杆205轴向方向延伸的通孔2231，所述卡扣槽2232和所述内凹部2233均与所述通孔2231相贯通，所述卡扣207收容于所述卡扣槽2232中与轴杆205的缺口20532和开槽20533配 合，所述扣片206收容于所述内凹部2233，与轴杆205的环形槽20531配合。
当展开柔性屏50而使卷筒201旋转时，轴杆205保持不动，第一端盖202跟随卷筒201旋转，第二端盖203保持不动，弹簧204固定于第一端盖202的一端跟随卷筒201旋转，弹簧204固定于第二端盖203的另一端保持不动，因此，弹簧204被扭转而发生弹性形变，产生将卷筒201回拉的回弹力。
由于转动限位结构的限制，卷筒201将无法自动回弹，除非用户手动推动使得第一主体10和第二主体20相对靠近，此时转动限位结构的摩擦力被用户的推力所抵消，弹簧204产生的回弹力带动卷筒201及柔性屏50收卷。当用户松手之后，由于弹簧204及卷筒201旋转的惯性作用，将克服转动限位结构的阻力而使卷筒201继续旋转，直至完全收卷。
当需要调节弹簧204的松紧程度时，可手动将卡扣207从卡扣槽2232内取出，然后通过螺丝刀旋转轴杆205的头端，使轴杆205发生旋转。由于第二端盖203的限位面2035与轴杆205的第二止位面P2之间的配合平面的相互抵接，轴杆205将带动第二端盖203旋转，进而带动固定于第二端盖203的弹簧204的另一端旋转。而此时第一端盖202受到柔性屏50的拉扯而保持不动，因此弹簧204固定于第一端盖202的一端也不会动。弹簧204的一端动而另一端不动，由此弹簧204的松紧程度就发生变化。调整完之后再将卡扣207插入卡扣槽2232，重新对轴杆205限位。需要注意的是只能以旋转半圈的整数倍的方式来调整弹簧204的松紧，否则调整完之后如果轴杆205的第一止位面P1和第二止位面P2没有位于竖直位置的话，卡扣207的定位槽将无法顺利地与轴杆205的第一止位面P1和第二止位面P2相抵接。
