具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
为了更好地理解本申请，下面结合图1至图8对本申请实施例进行描述。
参见图1和图2所示，本申请实施例提供一种支撑结构件10，其用于显示设备。支撑结构件10可以为柔性屏100提供安装基础。示例性地，柔性屏100指的是可以弯折或卷曲的屏体。
参见图1至图3所示，本申请实施例的支撑结构件10包括支撑架20和动力单元50。支撑架20具有屏体支撑面20a和内表面20b。屏体支撑面20a用于支撑柔性屏100，保证柔性屏100的平整度。内表面20b与屏体支撑面20a相背设置。示例性地，在用户使用包括支撑结构件10的显示设备时，屏体支撑面20a可以是面向用户的表面。
支撑架20包括第一支撑体21和第二支撑体22。第二支撑体22能够沿第一方向X相对于第一支撑体21移动。本实施方式中，第一支撑体21不移动，第二支撑体22移动。当然，也可根据需要令第一支撑体21移动，第二支撑体22不移动。在支撑结构件10上安装有柔性屏100后，第二支撑体22相对第一支撑体21沿第一方向X伸出时，屏体支撑面20a的面积会增大，从而柔性屏100展开的显示面积相对应地增大。第二支撑体22相 对第一支撑体21沿第一方向X缩回时，屏体支撑面20a的面积会减小，从而柔性屏100展开的显示面积相对应地减小。
第二支撑体22与动力单元50连接设置。动力单元50可以驱动第二支撑体22相对第一支撑体21移动，并随着第二支撑体22同步位移，对于动力单元50与第二支撑体22之间的具体结构关系将在后续介绍动力单元50结构时进行详细描述。
示例性地，动力单元50可以设置于支撑架20背向屏体支撑面20a的一侧，也即动力单元50设置于支撑架20的内表面20b侧。动力单元50位于支撑架20的内部。或者，动力单元50可以设置于支撑架20外侧，即动力单元50外置于支撑架20。
参见图4至图6所示，动力单元50设置于支撑架20的内表面20b侧。动力单元50包括第一传动机构51、第二传动机构52、屏体连接机构53以及驱动器54。第一传动机构51和第二传动机构52联动设置，第一传动机构51的至少部分与第二支撑体22连接固定，屏体连接机构53的至少部分与柔性屏100的移动端连接固定。其中，驱动器54通过第一传动机构51驱动第二支撑体22移动，并且驱动器54通过第一传动机构51以及第二传动机构52驱动屏体连接机构53移动，以使第二支撑体22和柔性屏100的移动端沿第一方向X同向移动。
需要说明的是，第一传动机构51和第二传动机构52联动设置指的是，第一传动机构51接收到驱动器54的动力时，第一传动机构51开始工作。同时，第一传动机构51可以将动力传递至第二传动机构52，从而第一传动机构51工作时，第二传动机构52也处于工作状态。
本申请实施例的支撑结构件10，可以用于为柔性屏100提供安装基础。在支撑结构件10与柔性屏100组装后，可以形成柔性屏100屏幕显示面积大小可调节变化的显示设备。在支撑结构件10中，第一支撑体21与第二支撑体22彼此可以相对移动，从而增大或减小屏体支撑面20a的面积。第二支撑体22安装于第一传动机构51，屏体连接机构53用于安装柔性屏100的移动端。具体地说，屏体连接机构53可以与第二支撑体22相对第一支撑体21沿第一方向X同向移动。在第二支撑体22沿第一方向X伸出时， 屏体连接机构53远离第一支撑体21移动，以用于展开柔性屏100，使得屏体支撑面20a一侧的柔性屏100显示面积增大。在第二支撑体22沿第一方向X缩回时，屏体连接机构53靠近第一支撑体21移动，以用于收回柔性屏100，使得屏体支撑面20a一侧的柔性屏100显示面积减小。此外，动力单元50可以通过第一传动机构51驱动第二支撑体22沿第一方向X移动，并且可以同时通过第一传动机构51和第二传动机构52驱动屏体连接机构53沿第一方向X移动，从而使得第二支撑体22和屏体连接机构53沿第一方向X同向移动。因此，本申请实施例支撑结构件10可以自由调节屏体支撑面20a的面积大小，从而在与柔性屏100组装后，可以自由调节柔性屏100的显示面积大小，以满足用户在不同使用场景下对屏幕显示面积大小的不同需求，提升用户体验满意度。
在一些实施例中，如图4至图6所示，第一传动机构51包括转接件511、基座512和传动件513。基座512内具有沿第一方向X延伸的容纳空间，传动件513设置在基座512内且沿第一方向X延伸，转接件511连接于传动件513且可相对传动件513沿第一方向X相对移动。
第一传动机构51通过转接件511连接于第一支撑体21，基座512连接于第二支撑体22，即传动单元50的转接件511固定在第一支撑体21上，基座512固定在第二支撑体22上。传动件513连接基座512和转接件511，其中传动件513与基座512在第一方向X上始终保持相对不动，且传动件513能够相对于转接件511可沿第一方向X移动。
驱动器54设置于基座512并且通过驱动传动件513相对于转接件511沿第一方向X移动，在这个过程中，由于传动件513与基座512在第一方向X上相对位置保持相对不变，而传动件513与转接件511沿第一方向相对移动，使得固定于基座512上的第二支撑体22会相对固定于转接件511上的第一支撑体21发生移动。可选地，驱动器54沿第二方向Y位于传动件513的一侧。
驱动器54将动力输出至传动件513后，传动件513可以相对转接件511移动，从而传动件513、基座512、驱动器54以及第二支撑体22均沿第一方向X相对第一支撑体21移动。示例性地，转接件511通过紧固件连 接于第一支撑体21。基座512通过紧固件连接于第二支撑体22。基座512可以是矩形状的框体。驱动器54可以是伺服电机或步进电机。
在一些示例中，传动件513为螺纹杆。传动件513沿第一方向X延伸且两端可转动连接于基座512。传动件513与转接件511螺纹连接。驱动器54驱动螺纹杆旋转时，螺纹杆相对于转接件511沿第一方向X移动。示例性地，驱动器54驱动螺纹杆顺时针旋转时，螺纹杆、基座512、驱动器54以及第二支撑体22沿第一方向X移动并远离第一支撑体21。驱动器54驱动螺纹杆逆时针旋转时，螺纹杆、基座512、驱动器54以及第二支撑体22沿第一方向X移动并靠近第一支撑体21。
采用螺纹杆旋转传动的方式，有利于提高可第二支撑体22的移动稳定性，降低第二支撑体22移动过程存在冲击而对柔性屏100产生瞬时冲击力的可能性，从而降低柔性屏100因受到瞬时冲击力而发生撕裂的可能性。示例性地，螺纹杆的两端可以通过滚动轴承或滑动轴承与基座512转动连接。
在一些实施例中，第一传动机构51还包括第一导轨514。第一导轨514连接于基座512。沿第二方向Y，传动件513和第一导轨514并排间隔设置。可选地，第一导轨514与传动件513均位于基座512内，且第一导轨514沿第二方向Y位于传动件513与驱动器54之间。
第一导轨514沿第一方向X可移动连接于转接件511。第一导轨514沿第一方向X延伸。设置第一导轨514，可以提高第二支撑体22移动过程稳定性，从而能够有利于降低第二支撑体22对柔性屏100造成的不良冲击而导致柔性屏100发生意外损坏的可能性。示例性地，第一导轨514的相对两端连接固定于基座512，而第一导轨514的中间部分可移动连接于转接件511。第一导轨514可以为导向杆。第一导轨514与转接件511可滑动连接。
在一些实施例中，请参阅图6和图7所示，第二传动机构52包括第一滚轮521、第二滚轮522以及柔性带523。沿第一方向X，第一滚轮521和第二滚轮522间隔设置于基座512。柔性带523绕过第一滚轮521和第二滚轮522。转接件511和屏体连接机构53分别连接固定于柔性带523。驱动 器54驱动基座512和第二支撑体22移动时，柔性带523可以带动屏体连接机构53移动。
第二传动机构52沿第二方向Y位于第一传动机构51的一侧，转接件511连接于第一支撑体21，而柔性带523连接于转接件511，从而驱动器54通过传动件513驱动基座512和第二支撑体22相对转接件511移动时，转接件511会带动柔性带523同步运动，从而柔性带523会带动第一滚轮521和第二滚轮522转动，同时柔性带523会牵拉屏体连接机构53以带动屏体连接机构53与第二支撑体21同向移动。因此，驱动器54输入的动力可以传递至第一传动机构51和第二支撑体22，同时也经过第一传动机构51传递至第二传动机构52和屏体连接机构53，从而实现第二支撑体22与屏体连接机构53同向移动，有利于保证屏体连接机构53与第二支撑体22运动同步性，降低屏体连接机构53与第二支撑体22中的一者相对于另一者存在运动滞后而导致柔性屏100承载较大拉伸力或冲击力而发生结构损坏的可能性。
在一些示例中，柔性带523为钢丝或同步带。柔性带523可以为一体式结构。
在一些示例中，沿第二方向Y，第一传动机构51位于柔性带523的一侧，而屏体连接机构53位于柔性带523的另一侧。沿第一方向X，第一传动机构51的转接件511的至少部分位于第一滚轮521和第二滚轮522之间。沿第一方向X，屏体连接机构53的至少部分位于第一滚轮521和第二滚轮522之间。示例性地，在第二支撑体22移动并靠近第一支撑体21，柔性屏100处于收回状态时，第一滚轮521靠近转接件511，而第二滚轮522靠近屏体连接机构53。在第二支撑体22移动并远离第一支撑体21，柔性屏100处于展开状态时，第二滚轮522靠近转接件511，而第一滚轮521靠近屏体连接机构53。
在一些实施例中，屏体连接机构53包括张紧件531。在屏体连接机构53上连接柔性屏100时，张紧件531用于张紧屏体连接机构53上待连接的柔性屏100。张紧件531用于沿第一方向X张紧屏体连接机构53，从而可以通过屏体连接机构53微调柔性屏100的张紧力，进一步保证柔性屏100 在展开或收回过程中保持张紧平整状态，提高柔性屏100显示效果，降低柔性屏100发生褶皱的可能性。
在一些实施例中，屏体连接机构53还包括屏体连接块532和传动块533。屏体连接块532用于连接柔性屏100。屏体连接块532和传动块533分别沿第一方向X可移动连接于第二支撑体22。第二传动机构52与传动块533连接，从而第二传动机构52可以将动力传递至传动块533。沿第一方向X，屏体连接块532位于传动块533靠近第一支撑体21的一侧。张紧件531能够沿第一方向X向屏体连接块532施加远离传动块533方向的推力。该推力始终朝向第一支撑体21。示例性地，沿第一方向X，张紧件531位于屏体连接块532和传动块533之间。示例性地，第二传动机构52包括柔性带523的实施例中，传动块533与柔性带523连接。
由于张紧件531能够始终沿第一方向X向屏体连接块532施加远离传动块533方向的推力，并且该推力可以保持恒定或小范围波动，因此在屏体连接块532上连接的柔性屏100展开或收回的过程中，张紧件531可以有利于保证柔性屏100的平整度，同时柔性屏100不易承载较大的拉伸力或不平稳的冲击力，有利于降低柔性屏100受到较大拉伸力或不平稳冲击力而出现显示异常或自身出现裂纹的可能性。
在一些实施例中，张紧件531为弹性件。在屏体连接块532上连接柔性屏100后，屏体连接块532和传动块533可以共同挤压弹性件，从而处于压缩状态的弹性件可以对屏体连接块532施加远离传动块533的推力。在一些示例中，在第二支撑体22伸出第一支撑体21，柔性屏100展开时，柔性带523可以带动传动块533移动，同时柔性屏100牵拉屏体连接块532跟随传动块533移动，从而屏体连接块532和传动块533之间的间隙可以维持不变，使得弹性件始终处于压缩状态，并且弹性件施加于屏体连接块532的推力为一恒定作用力。在第二支撑体22缩回第一支撑体21，柔性屏100收回时，柔性带523可以带动传动块533移动，而传动块533通过张紧件531推动屏体连接块532移动以收回柔性屏100，从而屏体连接块532和传动块533之间的间隙可以维持不变，使得弹性件始终处于压缩状态，并且弹性件施加于屏体连接块532的推力为一恒定作用力。因此，在柔性屏 100展开和收回的过程中，柔性屏100自身承载的拉伸力始终可以保持一致，有利于降低柔性屏100受到较大拉伸力或不平稳冲击力而出现显示异常或自身结构出现裂纹的可能性。
在一些实施例中，屏体连接块532和传动块533之间的最小间距等于弹性件处于最大压缩状态时的长度。或者，屏体连接块532和传动块533中的至少一者设置有容纳部。弹性件容纳于容纳部。容纳部的总深度等于弹性件处于最大压缩状态时的长度，从而屏体连接块532和传动块533共同压缩弹性件后，可以使得屏体连接块532和传动块533之间的最小间距等于零。示例性地，沿第一方向X，屏体连接块532面向传动块533的表面以及传动块533面向屏体连接块532的表面上均设置容纳部。
在一些实施例中，弹性件为螺旋弹簧或橡胶件。
在一些实施例中，参见图6和图7所示，动力单元50还包括第二导轨55。第二导轨55连接于第二支撑体22。第二导轨55沿第一方向X延伸。屏体连接块532和传动块533沿第一方向X可移动连接于第二导轨55。第二导轨55可以保证屏体连接块532和传动块533移动过程的平稳性，有利于降低屏体连接块532和传动块533因移动不平稳而出现瞬时冲击，从而对柔性屏100造成不良冲击的可能性。示例性地，沿第二方向Y，第一导轨514、传动件513和第二导轨55并排设置。示例性地，第一传动机构51通过基座512连接于第二支撑体21的实施例中，第二导轨55连接于基座512。第二导轨55的数量可以是两个以上，有利于进一步提高屏体连接块532和传动块533移动过程的平稳性。两个以上的第二导轨55沿第二方向Y并排设置。
在一些实施例中，第二导轨55为导向杆。屏体连接块532和传动块533设置有与导向杆形状相匹配的导向孔。示例性地，张紧件531为螺旋弹簧或橡胶件的实施例中，螺旋弹簧或橡胶件可以套设于导向杆的外周，从而导向杆可以约束限位螺旋弹簧或橡胶件，降低螺旋弹簧或橡胶件的中间部分在压缩过程中向一侧发生弯曲而导致螺旋弹簧或橡胶件弹性失效的可能性。
在一些实施例中，沿第二方向Y，两个以上的动力单元50间隔设置。 两个以上的动力单元50用于在第一方向X上为第二支撑体22提供动力，从而有利于进一步提高第二支撑体22移动过程的平稳性，降低对安装于屏体连接机构53上的柔性屏100造成不良冲击的可能性。
在一些实施例中，支撑结构件10还包括屏体固定件30和屏体转接件40。参见图3所示，屏体固定件30设置于第一支撑体21。屏体固定件30用于固定柔性屏100。屏体固定件30设置于支撑架20的屏体支撑面20a侧。柔性屏100的一端可以连接固定于屏体固定件30。屏体固定件30和第一支撑体21可以夹紧柔性屏100的端部，保证柔性屏100的连接稳定性，降低柔性屏100出现褶皱的可能性。示例性地，屏体固定件30为固定框。
屏体转接件40位于于第二支撑体22的一侧。屏体转接件40用于连接固定柔性屏100。屏体转接件40设置于支撑架20的内表面20b侧，也即位于支撑架20的内部。屏体转接件40连接于屏体连接机构53。在支撑结构件10上安装有柔性屏100后，柔性屏100远离屏体固定件30的一端朝向支撑架20的内表面20b侧折弯并且与屏体转接件40连接。屏体转接件40和屏体固定件30能够共同拉伸柔性屏100，以保持柔性屏100的平整度。示例性地，屏体转接件40为转接板。
在一些实施例中，动力单元50可以与第一支撑体21固定连接，即动力单元50可以驱动第二支撑体22移动，第一传动机构随着所述第二支撑体同步位移。
在一些实施例中，支撑架20还包括第一底板23和第二底板24。第一底板23和第一支撑体21连接。第二底板24和第二支撑体22连接。动力单元50的至少部分以及屏体转接件40的至少部分容纳于第二底板23和第二支撑体22之间。
在一些实施例中，支撑架20还包括滚轴25。滚轴25用于支承柔性屏100。沿第一方向X，滚轴25设置于第二支撑体22远离第一支撑体21的一端。滚轴25沿第二方向Y的相对两端可转动连接于第二支撑体22。第一方向X和第二方向Y相互垂直。柔性屏100的一端连接固定于第一支撑体21，而柔性屏100的一部分折弯并与滚轴25抵接。柔性屏100绕过滚轴25的另一端可以与屏体连接机构53连接。柔性屏100展开或缩回时，滚轴 25会发生滚动。滚轴25可以降低柔性屏100展开或收回过程的阻力，也可以降低柔性屏100与第二支撑体22直接接触发生摩擦损伤的可能性。
在一些实施例中，第一支撑体21包括多个第一梳齿。第二的支撑体22包括多个第二梳齿。第一支撑体21和第二支撑体22通过第一梳齿和第二梳齿插接连接。第一梳齿插入相邻两个第二梳齿之间，而第二梳齿插入相邻两个第一梳齿之间。
在一些实施例中，第二支撑体22与动力单元50连接设置，即驱动器54通过第一传动机构51驱动第二支撑体22相对第一支撑体21以第一速率V1移动。由于第二传动机构52与所述第一传动机构51是等速运动，即驱动器54通过第一传动机构51以及第二传动机构52驱动屏体连接机构53相对第二支撑体22以第一速率V1移动，同时驱动器54通过第一传动机构51以及第二传动机构52驱动屏体连接机构53相对第一支撑体21以第二速率V2移动，其中，V2＝2V1。由于屏体连接机构53与第二支撑体22之间以第一速率V1移动，第二支撑体22相对于第一支撑体21以第一速率V1移动，则屏体连接机构53相对于第一支撑体21以第二速率V2移动；因此，第二支撑体22相对于第一支撑体21沿着第一方向位移距离L1，屏体连接机构53相对于第二支撑体22沿着第一方向位移距离L2，屏体连接机构53相对于第一支撑体21的位移距离为L3，其中，L3＝L1+L2。由于屏体连接机构53相对于第二支撑体22的移动速率相同则L1＝L2，那么L3＝2L1。即柔性屏100的第一端和第二端的总移动距离为2L1，使得柔性屏100能够跟随支撑体的伸缩同步展开或收回，避免造成柔性屏100撕裂或褶皱现象。由于第一支撑体21不运动，所述驱动器54通过所述第一传动机构51驱动所述第二支撑体22以第一速率V1移动。所述驱动器54通过所述第一传动机构51以及所述第二传动机构52驱动所述屏体连接机构53以第二速率V2移动，其中，V2＝2V1。
在一些示例中，传动件513为螺纹杆。传动件513的两端可转动连接于基座512。传动件513与转接件511螺纹连接。驱动器54驱动螺纹杆旋转时，螺纹杆相对于转接件511沿第一方向X移动。示例性地，驱动器54驱动螺纹杆顺时针旋转时，螺纹杆、基座512、驱动器54以及可移动的支 撑体21沿第一方向X移动并远离第一支撑体21。驱动器54驱动螺纹杆逆时针旋转时，螺纹杆、基座512、驱动器54以及第二支撑体22沿第一方向X移动并靠近第一支撑体21。
参见图8所示，本申请实施例还提供一种显示设备200。显示设备200包括柔性屏100以及上述实施例的支撑结构件10。柔性屏100用于显示图像。支撑架20的屏体支撑面20a用于支撑柔性屏100。柔性屏100的一端连接于第一支撑体21，另一端折弯设置于第二支撑体22远离屏体支撑面20a的一侧并且连接于屏体连接机构53。动力单元50的驱动器54驱动屏体连接机构53与第二支撑体22沿第一方向X同向移动时，柔性屏100收纳于第二支撑体22内的部分与柔性屏100位于第二支撑体22外的部分重叠面积增大或减小，以增大或减小位于屏体支撑面上的柔性屏13的面积，以此调节柔性屏100外露的显示面积的大小。本实施方式中，该显示设备200可以是手机，在本申请其他可选的实施方式中，该显示设备200还可以是平板电脑、笔记本、显示器等任意具备显示功能的设备。
在一些实施例中，显示设备200还包括电池300和电路板400。电池300和电路板400均位于支撑架20的内表面20b侧。电池300和电路板400可以与第一支撑体21对应。电池300用于为显示设备200提供电力，而电路板400可以用于采集数据和处理分析数据，以保证显示设备200可以正常显示图像等。
由于显示设备200包括前述任一种实施方式所述的支撑结构件10，因此显示设备200具有前述任一种实施方式所述的支撑结构件10的有益效果，在此不再详细赘述。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件，尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
