技术领域
本申请涉及显示技术领域，具体涉及一种支撑结构件以及显示设备。
背景技术
随着科学技术的发展，移动终端设备得到广泛应用，成为人类生活中的基本用品之一。移动终端设备经历了由小屏到大屏的发展过程。但是移动终端设备的屏幕都是固定不变的。然而，在人们处理不同的工作时，例如通话、游戏娱乐或处理文档等，往往对显示屏的大小有不同的需求，因此不能改变屏幕显示面积大小的移动终端设备不能很好地满足人们的日常需求。
发明内容
本申请实施例提供一种支撑结构件以及显示设备，能够改变显示面积大小，满足人们日常需求。
一方面，本申请实施例提出了一种支撑结构件，用于显示设备，支撑结构件包括：支撑架，具有屏体支撑面和与屏体支撑面相对设置的内表面，支撑架包括第一支撑体和第二支撑体，第二支撑体沿第一方向可移动地连接于第一支撑体；屏体转接件，设置于支撑架上且用于引导屏体的展开或收回，屏体转接件可移动连接于第二支撑体；动力组件，设置于支撑架上，第二支撑体及屏体转接件均与动力组件连接设置，动力组件驱动第二支撑 体相对于第一支撑体伸出或缩回，并使得屏体转接件与第二支撑体沿第一方向同时移动。
另一个方面，本申请实施例还提供一种显示设备，包括：柔性屏；如前任一实施方式的支撑结构件，屏体支撑面用于支撑柔性屏，柔性屏的一端连接于屏体固定件，另一端折弯收纳于第二支撑体内并且连接于屏体转接件，动力组件驱动第二支撑体相对于第一支撑体伸出或缩回，并使得屏体转接件与第二支撑体沿第一方向同步移动时，柔性屏收纳于第二支撑体内的部分能够展开或收回。
根据本申请实施例的支撑结构件，可以用于为柔性屏提供安装基础。在支撑结构件与柔性屏组装后，可以形成柔性屏屏幕显示面积大小可调节变化的显示设备。在支撑结构件中，第一支撑体和第二支撑体彼此可以相对移动，从而增大或减小屏体支撑面的面积。屏体固定件和屏体转接件之间用于安装柔性屏。屏体固定件和屏体转接件能够共同拉紧柔性屏。屏体转接件可以与第二支撑体沿第一方向移动。在第二支撑体伸出时，屏体转接件远离第一支撑体移动，以用于展开柔性屏，使得屏体支撑面一侧的柔性屏显示面积增大。在第二支撑体缩回时，屏体转接件靠近第一支撑体移动，以用于收回柔性屏，使得屏体支撑面一侧的柔性屏显示面积减小。动力组件能够驱动第二支撑体和屏体转接件沿第一方向移动。这样，本申请实施例支撑结构件可以自由调节屏体支撑面的面积大小，从而在与柔性屏组装后，可以自由调节柔性屏的显示面积大小，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。

具体实施方式
为了更好地理解本申请，下面结合图1至图9对本申请实施例进行描述。
如图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。
如图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、屏体固定件30、屏体转接件40和动力组件50。支撑架20具有屏体支撑面20a和与内表面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相对设置。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沿第一方向X可移动地连接于第一支撑体21。在第二支撑体22受到外力作用时可以沿第一方向X移动，从而相对于第一支撑体21伸出或缩回。在支撑结构件10上安装柔性屏100后，第二支撑体22相对第一支撑体21伸出时，屏体支撑面20a的展开面积会增大，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缩回时，屏体支撑面20a的展开面积会减小，从而柔性屏100展开的显示面积相对应地减小。
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。屏体固定件30连接于第一支撑体21。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包括与第一支撑体21连接的固定板31和连接柔性屏100一端的固定框32。固定框32抵压于柔性屏100背向第一支撑体21的一侧并且与第一支撑体21连接，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。
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。在支撑结构件10上安装柔性屏100后，柔性屏100远离屏体固定件30的另一端朝向支撑架20的内表面20b折弯而与屏体转接件40连接，并且收纳于支撑架20的内部。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。在第二支撑体22沿第一方向X相对于第一支撑体21伸出时，屏体转接件40也相对第二支撑体22沿第一方向X移动，从而可以释放柔性屏100，以使柔性屏100位于支撑架20内部的一部分显露出来并支撑于屏体支撑面20a的展开部分，增大柔性屏100的显示面积。在第二支撑体22沿第一方向X相对于第一支撑体21缩回时，屏体转接件40也相对第二支撑体22沿第一方向X移动，从而收回柔性屏100，以使柔性屏100位于屏体支撑面20a的展开部分的一部分移动至支撑架20的内部，减小柔性屏100的显示面积。
参照图2至图6，动力组件50设置于支撑架20的第二支撑体22的内表面20b一侧，即收容于第二支撑体22的内部并抵接第二支撑体22的内壁221。第二支撑体22以及屏体转接件40均与动力组件50连接设置。动力组件50可以驱动第二支撑体22相对于第一支撑体21伸出或缩回，并带动屏体转接件40与第二支撑体22沿第一方向X同时移动。
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和第二支撑体22可以相对移动，从而增大或减小屏体支撑面20a的展开面积。屏体固定件30和屏体转接件40用于固定安装柔性屏100以共同拉紧柔性屏100。屏体转接件40可以与第二支撑体22沿第一方向X移动。在第二支撑体22伸出时，屏体转接件40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缩回时，屏体转接件40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。动力组件50能够驱动第二支撑体22和屏体转接件40沿第一方向X移动。这样，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，支撑架20还包括连接于第一支撑体21外侧的第一底板23和连接于第二支撑体22外侧的第二底板24。屏体转接件40以及动力组件50容纳于第二底板24和第二支撑体22形成的空间内。
在一些实施例中，第一支撑体21包括多个第一梳齿。第二支撑体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，即，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，如图3和图4所示，动力组件50包括与第二支撑体22连接的第一驱动机构51和与屏体转接件40连接的第二驱动机构52。动力组件50通过第一驱动机构51和第二驱动机构52分别用于驱动第二支撑体22和屏体转接件40沿第一方向X移动。这样，可以实现第二支撑体22和屏体转接件40单独驱动，使得第二支撑体22和屏体转接件40的移动过程各自独立，互不干涉。
在一些实施例中，第一驱动机构51包括沿第一方向X延伸的第一螺纹杆511，动力组件50还包括沿第一方向X位于第一驱动机构51一端的第一连接座56。第一连接座56设置有与第一支撑体21固定连接的凸柱以及在垂直于第一方向X和第二方向Y的第三方向上贯穿设置的第一固定孔561。由于第一支撑体21保持固定不动，第一支撑体21与第一连接座56固定连接，第一连接座56螺纹连接于第一螺纹杆511，因此第一螺纹杆511相对第二支撑体22转动时，第一螺纹杆511和第二支撑体22会同步相对于第一支撑体21沿第一方向X移动，以使第二支撑体22相对于第一支撑体21伸出或缩回。采用第一螺纹杆511旋转传动的方式，有利于提高第二支撑体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，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。
如图5所示，第一螺纹杆511和第一连接座56螺纹连接。第一螺纹杆 511转动时，第一螺纹杆511相对第一连接座56可以在第一方向X上移动，以带动第二支撑体22移动。
在一些实施例中，如图3至图9所示，第二驱动机构52包括沿第一方向X延伸的第二螺纹杆521，动力组件50还包括沿第一方向X位于第二驱动机构52一端的第二连接座57，第二连接座57螺纹连接于第二螺纹杆521。第一连接座56和第二连接座57沿第一方向X分别位于第一驱动机构51和第二驱动机构52的两端。第二连接座57包括朝向第二底板24凸设的第一限位凸柱571和在第三方向贯穿设置的第二固定孔572。第三方向垂直于第一方向X和第二方向Y所在平面。
屏体转接件40沿第二方向Y的两端同时设置有第一条形孔41和第二条形孔42。支撑结构件10还包括用于固定柔性屏100的屏体转接件40和动力组件50的紧固件80，紧固件80贯穿屏体转接件40的第一条形孔41和第二连接座57的第二固定孔572，使屏体转接件40和第二连接座57固定连接，防止屏体转接件40与动力组件50脱落分离。第二连接座57的第一限位凸柱571伸入屏体转接件40的第二条形孔42内并与第二条形孔42的内壁抵接。
参阅图6，第一条形孔41和第二条形孔42设置为沿第一方向X延伸的狭长型孔状结构，使得屏体转接件40具有位置可微调的优点，从而可以微调屏体转接件40的位置以使柔性屏100的张紧程度处于预定程度。在本申请中，第一条形孔41和第二条形孔42沿第二方向Y间隔设置。
动力组件50还包括与第二支撑体22固定连接的第一安装座53和第二安装座54。第一安装座53和第二安装座54沿第一方向X间隔设置于第二支撑体22的内部。第一螺纹杆511和第二螺纹杆521的两端各自连接于第一安装座53和第二安装座54。第一螺纹杆511和第二螺纹杆521沿第二方向Y间隔设置。第一方向X与第二方向Y相垂直。第一安装座53和第二安装座54之间沿第一方向X的间距可以限定第二支撑件22和屏体转接件40的最大移动量。
第二螺纹杆521转动时，带动屏体转接件40相对第二支撑体22沿第一方向X同时移动。第一螺纹杆511转动时，由于第一支撑体21保持固定 不动且第一连接座56与第一支撑体21固定连接而保持固定不动，从而第一螺纹杆511、第二螺纹杆521以及第二支撑体22相对于第一支撑体21沿第一方向X同步移动。第二螺纹杆521转动时，由于屏体转接件40和第二连接座57固定连接，第二螺纹杆521驱动第二连接座57带动屏体转接件40相对于第二支撑体22沿第一方向X移动。采用第二螺纹杆521旋转传动的方式，有利于提高屏体转接件40的移动稳定性，降低屏体转接件40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。
第一螺纹杆511和第二螺纹杆521具有靠近第一支撑体21的动力输入端55，动力输入端55可以驱动第一螺纹杆511和第二螺纹杆521旋转。动力组件50还包括与动力输入端55相连接的伺服电机或步进电机等。动力输入端55可以为齿轮结构，第一螺纹杆511的动力输入端55和第二螺纹杆521的动力输入端55彼此啮合传动。或者，使用一条同步传动带或同步传动链连接第一螺纹杆511的动力输入端55和第二螺纹杆521的动力输入端55。
第一螺纹杆511和第二螺纹杆521同步转动，保证第二支撑体22和屏体转接件40两者同时移动，从而尽可能避免第一螺纹杆511先于第二螺纹杆521转动而造成第二支撑体22伸出时，屏体转接件40还未能移动展开柔性屏100，导致第二支撑体22对柔性屏100施加的应力过大而令柔性屏100拉伸过度发生撕裂的现象。或可避免第二螺纹杆521先于第一螺纹杆511转动而造成第二支撑体22未缩回时，屏体转接件40已开始移动收回柔性屏100，导致第二支撑体22对柔性屏100施加应力过大而令柔性屏100拉伸过度发生撕裂的现象。
在一些实施例中，如图5所示，第一驱动机构51还包括沿第一方向X延伸并与第一连接座56滑动连接的第一导轨512，第一导轨512贯穿第一连接座56且沿第一方向X的两端连接固定于第一安装座53和第二安装座54。第二支撑体22沿第一方向X移动时，第一导轨512跟随第二支撑体22相对第一支撑体21同步移动。设置第一导轨512，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。在一些实施例中，第二驱动机构52还包括沿第一方向X延伸并与第二连接座57滑动连接的第二导轨522，第二导轨522贯穿第二连接座57且沿第一方向X的两端连接固定于第一安装座53和第二安装座54。第二支撑体22沿第一方向X移动时，第二导轨522跟随第二支撑体22同步移动。设置第二导轨522，可以提高屏体转接件40移动过程的稳定性，从而能够有利于降低屏体转接件40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。
在一些可选的实施例中，第一导轨512和第二导轨522沿第二方向Y间隔设置且分别位于第一螺纹杆511和第二螺纹杆521两外侧。在一些实施例中，如图6和图7所示，支撑结构件10还包括张紧组件60。张紧组件60连接第二支撑体22和屏体转接件40。张紧组件60用于沿第一方向X张紧屏体转接件40，从而可以通过屏体转接件40微调柔性屏100的张紧力，进一步保证柔性屏100保持张紧平整状态，提高显示效果。在一些可选的实施例中，张紧组件60包括弹性件61。弹性件61的一端连接于第二支撑体22，另一端连接于屏体转接件40。弹性件61用于对屏体转接件40施加沿第一方向X的拉应力。在第二支撑体22相对第一支撑体21伸出，而屏体转接件40也远离第一支撑体21移动时，弹性件61被拉长，其自身蓄积的弹性势能会增大。可选地，弹性件61可以是弹簧或橡胶条。示例性地，弹性件61的一端通过螺钉62连接固定于第二支撑体22上，另一端挂接于屏体转接件40上。在一些可选的实施例中，在通过第一驱动机构51驱动第二支撑体22移动或者第二驱动机构52驱动屏体转接件40移动的实施例中，第一螺纹杆511和第一支撑体21之间或者第二螺纹杆521和屏体转接件40之间会存在沿第一方向X的游隙，导致第一螺纹杆511转动一定角度补偿游隙时，第二支撑体22却未能同步移动，同样第二螺纹杆521转动一定角度补偿游隙时，屏体转接件40却未能同步移动。在弹性件61的作用下，可以消除游隙的不良影响，保证传动平稳、同步。
在一些实施例中，如图6和图8所示，支撑结构件10还包括设置于支撑架20的内表面20b并与第二支撑体22及屏体转接件40连接设置的导向 组件90。导向组件90与动力组件50沿第二方向Y位于支撑架20两端。导向组件90用于在第一方向X上为第二支撑体22和屏体转接件40提供导向，从而有利于进一步提高第二支撑体22和屏体转接件40移动过程的平稳性，降低对安装于屏体固定件30和屏体转接件40之间的柔性屏100造成不良冲击力的可能性。
在一些可选的实施例中，导向组件90包括沿第一方向X间隔设置的第一导轨固定座91和第二导轨固定座92以及两端固定连接于第一导轨固定座91和第二导轨固定座92的第三导轨93和第四导轨94。第一导轨固定座91和第二导轨固定座92固定于第二支撑体22。第二支撑体22沿第一方向X移动时，第二支撑体22、第一导轨固定座91、第二导轨固定座92、第三导轨93和第四导轨94均可以沿第一方向X同步移动。导向组件90还包括分别与第三导轨93滑动连接的第一导向座95及套设在第四导轨94上并与第四导轨94滑动连接的第二导向座96。第一支撑体21与第一导向座95固定连接。第一导向座95包括朝向第二支撑体22凸伸以与第二支撑体22固定连接的的凸柱及沿第三方向贯穿设置的第一连接孔951，第二导向座96包括沿第三方向贯穿设置的第二连接孔961及朝向屏体转接件40凸伸的第二限位凸柱962。第二限位凸柱962与屏体转接件40对应一端的第二条形孔42卡扣配合，通过紧固件80与屏体转接件40对应一端的第一条形孔41及第二导向座96的第二连接孔961固定连接来实现屏体转接件40与第二导向座96的固定连接。第二螺纹杆521驱动屏体转接件40沿第一方向X移动时，屏体转接件40带动转第二导向座96在第四导轨94上移动，也即第二导向座96从第一导轨固定座91朝第二导轨固定座92移动，或者从第二导轨固定座92朝第一导轨固定座91移动。
在一些实施例中，如图3所示，支撑架20还包括滚轴25。滚轴25用于支承柔性屏100。滚轴25设置于第二支撑体22内部远离第一支撑体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。柔性屏100的一端连接固定于屏体固定件30，而柔性屏100的中间部分折弯并与滚轴25抵接。柔性屏100绕过滚轴25的另一端与屏体转接件40连接。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。
参见图9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的一端连接于屏体固定件30，另一端折弯收纳于第二支撑体22内并且连接于屏体转接件40。动力组件50驱动第二支撑体22相对于第一支撑体21伸出或缩回，并使得屏体转接件40与第二支撑体22沿第一方向X同时移动时，柔性屏100收纳于第二支撑体22内的部分能够展开或收回，以调节柔性屏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，并且与第一支撑体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。
