详细描述
为使本公开的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本公开作进一步详细的说明。显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本公开实施例提供了一种显示装置，所述显示装置可以是卷曲式的显示装置。具体地，所述显示装置可以作为电子设备上的显示模块使用，也可以作为电子设备的辅助装置，在需要获得较大的显示面积的情况下，将所述显示装置电连接至电子设备上，再将所述显示装置展开使用，本公开实施例对于所述显示装置的具体使用场景可以不做具体限定。
参照图1，示出了本公开的一种显示装置处于卷曲状态的结构示意图，参照图2，示出了图1所述的显示装置处于展开状态的结构示意图，参照图3，示出了图2所述的显示装置的反向结构示意图，参照图4，示出了图2所示的显示装置的侧向结构示意图。所述显示装置具体可以包括：第一壳体10、第二壳体11、柔性屏幕12、支撑带13以及伸缩杆14；其中，
第一壳体10与第二壳体11相对设置，且第一壳体10在第二壳体11相对的位置设置有开口101；
柔性屏幕12的一端卷设于第一壳体10内，另一端从开口101伸出且固定于第二壳体11；
支撑带13的一端卷设于第一壳体10内，另一端从开口101伸出且固定于第二壳体11，支撑带13伸出于第一壳体10的部分贴合于柔性屏幕12的底部；
伸缩杆14设置于支撑带13的底部，且伸缩杆14的一端固定于第一壳体10，另一端固定于第二壳体11。
如图1所示，在所述显示装置处于卷曲状态的情况下，大部分的柔性屏幕12被卷曲在第一壳体10内，所述显示装置的显示区A面积较小。如图2所示，在所述显示装置处于展开状态下的情况下，大部分的柔性屏幕12可以从第一壳体10拉出，显示区A面积较大。
本公开实施例中，在需要展开柔性屏幕12以获得较大的显示面积的情况下，可以通过拉伸第二壳体11，将柔性屏幕12和支撑带13从第一壳体10中拉出，由于支撑带13伸出于第一壳体10的部分贴合于柔性屏幕12的底部，因此，支撑带13可以用于实现对柔性屏幕12的底部支撑。并且，由于支撑带13的底部设置有伸缩杆14，伸缩杆14可以用于支撑支撑带13，提高支撑带13对于柔性屏幕12的支撑强度。这样，既可以避免柔性屏幕12发生局部变形，而且，在柔性屏幕12受到按压的情况下，还可以避免柔性屏幕12发生晃动，有利于在柔性屏幕12上进行触控操作。
本公开实施例中，第一壳体10内设置有第一卷轴机构15和第二卷轴机构16；柔性屏幕12的一端固定在第一卷轴机构15上，且绕接于第一卷轴机构15；支撑带13的一端固定在第二卷轴机构16上，且绕接于第二卷轴机构16。
具体地，第一卷轴机构15、第二卷轴机构16皆可以转动连接于第一壳体10内。如图4所示，在第一卷轴机构15逆时针转动的情况下，可以增大柔性屏幕12卷设在第一卷轴机构15上的面积，减小所述显示装置的显示区A的面积，在第一卷轴机构15顺时针转动的情况下，可以减少柔性屏幕12卷设在第一卷轴机构15上的面积，增大所述显示装置的显示区A的面积。同理，在第二卷轴机构16逆时针转动的情况下，可以增大支撑带13卷设在第二卷轴机构16上的面积，减小所述显示装置的显示区A的面积，在第二卷轴机构16顺时针转动的情况下，可以减少支撑带13卷设在第二卷轴机构16上的面积，增大所述显示装置的显示区A的面积。
可选地，第一卷轴机构15可以包括相对间隔设置的主动轴151和从动轴152，以及，绕接在主动轴151和从动轴152外的履带153；柔性屏幕12的一端固定于履带153，且绕接于履带153；主动轴151、从动轴152可转动的连接于第一壳体10内；主动轴151上连接有第一驱动件(图中未示出)，所述第一驱动件被配置为驱动主动轴151转动，以带动履带153朝向将柔性屏幕 12卷曲至第一壳体12内的方向转动。
具体地，由于柔性屏幕12的一端固定于履带153，履带153绕接在主动轴151和从动轴152外，因此，在需要将柔性屏幕12从第一壳体10内拉出的情况下，可以通过拉伸第二壳体11将柔性屏幕12从第一壳体10内拉出，并带动履带153、主动轴151、从动轴152沿顺时针方向转动，减小柔性屏幕12卷设在履带153上的面积。在需要将柔性屏幕12卷设收回至第一壳体10内的情况下，可以由所述第一驱动件驱动主动轴151逆时针转动，并通过主动轴151的逆时针转动带过从动轴152、履带153逆时针转动，增大柔性屏幕12卷设在履带153上的面积。
本公开实施例中，通过在第一卷轴机构15上设置相对间隔设置的主动轴151和从动轴152，并将柔性屏幕12通过履带153绕接在主动轴151和从动轴152上，可以使得主动轴151和从动轴152之间的间距可根据柔性屏幕12的张紧力要求进行调节，避免柔性屏幕12出现张紧力过大导致损坏的现象，提高柔性屏幕12的使用寿命。
需要说明的是，在实际应用中，主动轴151和从动轴152的位置还可以互换，本公开实施例对于主动轴151、从动轴152的具体设置位置可以不做限定。
可选地，所述第一驱动件为扭簧，具体地，所述扭簧可以套接在主动轴151上。在将柔性屏幕12处于图2所示展开状态的情况下，所述扭簧可以给所述给主动轴151施加逆时针转动的回复力，以通过主动轴151的逆时针转动带动履带153逆时针转动，以使柔性屏幕12可以自动卷设于履带153上，提高用户的使用体验。
可以理解的是，在具体地应用中，本领域技术人员还可以根据实际需要选择电机、电动机以及液压马达等驱动件作为所述第一驱动件，本公开实施例对于所述第一驱动件的具体内容可以不做限定。
在一些可选的实施例中，主动轴151的外表面设置有多个凸起部；履带153与主动轴151贴合的表面设置有多个凹槽，所述凹槽与所述凸起部啮合，履带153背离主动轴151的表面为光滑表面。
具体地，由于履带153上的凹槽与主动轴151上的凸起部啮合，可以增大履带153与主动轴151之间的摩擦力，防止履带153与主动轴11打滑，进 而，可以提升主动轴151和从动轴152之间的联动性。而将履带153背离主动轴151的表面设置为光滑表面，则可以避免履带153损坏卷设于其上的柔性屏幕12，提高柔性屏幕12的使用寿命。
具体地，主动轴151上的凸起部可以是齿轮、纹理或者其他能够增大表面粗糙度的结构，本公开实施例对于所述凸起部的具体形式可以不做限定。
可选地，第二卷轴机构16可以包括转轴161以及第二驱动件(图中未示出)；支撑带13的一端固定于转轴161，且绕接于转轴161；转轴161可转动的连接于第一壳体10内；所述第二驱动件与转轴161连接，所述第二驱动件被配置为驱动转轴161转动，以带动转轴161朝向将支撑带13卷曲至第一壳体10内的方向转动。
在实际应用中，第二卷轴机构16和第一卷轴机构15的运动可以保持一致，以使得支撑带13可以充分的支撑柔性屏幕12，实现对柔性屏幕12的底部支撑。
可选地，所述第二驱动件为扭簧。具体地，所述扭簧可以套接在转轴161上。在将柔性屏幕12处于图2所示展开状态的情况下，所述扭簧可以给所述给转轴161施加逆时针转动的回复力，以通过转轴161的逆时针转动带动支撑带13逆时针转动，以使支撑带13可以自动卷设于转轴161上，提高用户的使用体验。
可以理解的是，在具体地应用中，本领域技术人员还可以根据实际需要选择电机、电动机以及液压马达等驱动件作为所述第二驱动件，本公开实施例对于所述第二驱动件的具体内容可以不做限定。
在本公开的一些实施例中，所述显示装置还可以包括：夹紧机构17，夹紧机构17设置于第一壳体10内，且靠近开口101，夹紧机构101可以夹持柔性屏幕12和支撑带13，以使支撑带13伸出于第一壳体10的部分贴合于柔性屏幕12的底部。
在实际应用中，由于夹紧机构17靠近第一壳体10的开口101设置，且可以夹持柔性屏幕12和支撑带13，因此，在柔性屏幕12、支撑带13从第一壳体10的开口101伸出前，夹紧机构17可以将柔性屏幕12和支撑带13夹持至贴合的状态，以使得支撑带13伸出于第一壳体10的部分贴合于柔性屏幕12的底部，提高支撑带13对于柔性屏幕12的支撑可靠性。
可选地，夹紧机构17可以包括：相对间隔设置的第一辊轮171和第二辊轮172，柔性屏幕12、支撑带13可以夹持于第一辊轮171和第二辊轮172之间。
在实际应用中，第一辊轮171和第二辊轮172可以相对设置并形成一间隙，以使得柔性屏幕12和支撑带13之间可以从该间隙通过，这样，一方面，可以使得第一辊轮171和第二辊轮172对柔性屏幕12、支撑带13形成合理的夹持力，另一方面，又可以避免第一辊轮171和第二辊轮172之间的夹持力过大对柔性屏幕12造成不良影响。
在本公开的一些实施例中，柔性屏幕12的底部设置铁磁膜，所述铁磁膜可以用于改善柔性屏幕12弯折后展开翘曲问题，并帮助柔性屏幕12在展开状态的回弹及支撑性。为了实现对于柔性屏幕12的充分支撑并避免减小影响到柔性屏幕12的柔性，所述铁磁膜的厚度可以优选为20微米～150微米。
具体地，所述铁磁膜可以采用铁、钢、镍、钴等铁磁材料制成。示例地，所述铁磁膜可以为钢片层(厚度为20微米～30微米)，或者具有多孔结构的钢片层(厚度在150微米以下)。
参照图5，示出了本公开的一种支撑带的结构示意图，参照图6，示出了图5所示的支撑带的侧面剖面结构示意图，如图5、图6所示，支撑带13可以包括底膜131以及多个金属片132，多个金属片132沿支撑带13的展开方向并排贴附于底膜131，以使得支撑带13具备可卷曲的柔性，金属片132靠近柔性屏幕12设置，金属片132与所述铁磁膜磁性吸附连接。
在实际应用中，由于支撑带13设置有金属片132，而金属片132又具备较高的强度，因此，可以提高支撑带13对于柔性屏幕12的支撑可靠性。并且，由于金属片132与柔性屏幕12底部的铁磁膜磁性吸附连接，因此，可以使得支撑带13伸出于第一壳体10的部分与柔性屏幕12底部的连接较为可靠，进一步提升支撑带13对于柔性屏幕12的支撑可靠性。
可选地，金属片132上靠近柔性屏幕12的一侧设置有凹槽，所述凹槽内嵌设有磁性件133，磁性件133可以用于对柔性屏幕12底部的铁磁膜形成磁性吸附作用。
具体地，磁性件133可以为磁钢、磁铁等能够产生磁性吸附力的部件，金属片132可以为钢片、铝片或者合金片等，本公开实施例对于磁性件133、 金属片132的具体内容可以不做限定。
本公开实施例中，磁性件133的外表面与金属片132的外表面平齐，这样，以使得磁性件133、金属片132与柔性屏幕12的底部充分接触，提高支撑带13与柔性屏幕12之间的连接可靠性，进而，可以提高支撑带13对于柔性屏幕12的支撑可靠性。
在实际应用中，金属片132上设置有多个凹槽，且所述多个凹槽至少设置于金属片132的中央区域和两端的边缘区域，以使得磁性件133相应可以设置于金属片132的中央区域和两端的边缘区域。这样，就可以使得金属片132的边缘区域和中央区域皆可对柔性屏幕12上的铁磁膜产生磁性吸附的作用，进一步提高支撑带13与柔性屏幕12之间的连接可靠性。
具体地，金属片131可以为长条形金属片，金属片131的两端可以为沿金属片131长度方向上的两端。
可以理解的是，图5、图6中仅示出了每个金属片131上皆设置有磁性件133的情况，而在实际应用中，也可以选在在部分金属片131上设置磁性件133，本公开实施例对此不做限定。
在本公开实施例的另一些可选实施例中，金属片132可以由磁性材料制成。具体地，所述磁性材料可以为磁铁、磁钢等能够产生磁性吸附作用的材料。在实际应用中，在金属片132采用磁性材料制成的情况下，可以使得金属片132对柔性屏幕12底部的铁磁膜实现全面的磁性吸附作用，提高支撑带13与柔性屏幕12之间的连接可靠性。
可以理解的是，在实际应用中，可以选择将金属片132由磁性材料制成，或者，可以选择在金属片132设置磁性件133，或者以上两种方式的组合。
在实际应用中，为了避免柔性屏幕12底部的铁磁膜与支撑带13之间的磁性吸附力对柔性屏幕12的显示面板造成不良影响，在柔性屏幕12的显示面板与铁磁膜之间可以设置一层柔性的电磁屏蔽层，以屏蔽上述磁性吸附力。
可选地，底膜131可以包括：聚酰亚胺薄膜、热塑性聚酯膜或者织布中的至少一种，以使得底膜131可以兼顾较好的柔性和较高的强度。
参照图7，示出了本公开的一种伸缩杆的轴向结构示意图，参照图8，示出了图7所示的伸缩杆的某一角度的结构示意图，参照图9，示出了图8所示的伸缩杆的反向结构示意图，伸缩杆14具体可以包括多节依次滑动连接的连 接杆141，相邻的连接杆141中，其中一节连接杆141可嵌设于另一节连接杆141中；其中，多节连接杆141中，与支撑带13连接的第一侧面B平齐，以使得每一节连接杆141皆可以与支撑带13贴合，以提高伸缩杆14对于支撑带13的支撑可靠性。
具体地，可以将连接杆141设置为中空的框架结构，并在框架结构的侧壁上设置导槽142，以使得相邻的连接杆141中，其中一节连接杆141可嵌设于另一节连接杆141侧壁的导槽142中，以使多节连接杆141中，与支撑带13连接的第一侧面B平齐。

本公开实施例中，所述柔性屏幕的一端卷设于所述第一壳体内，另一端从所述开口伸出且固定于所述第二壳体；所述支撑带的一端卷设于所述第一壳体内，另一端从所述开口伸出且固定于所述第二壳体。在需要展开所述柔性屏幕的情况下，可以通过拉伸所述第二壳体，将所述柔性屏幕和所述支撑带从所述第一壳体中拉出，由于所述支撑带伸出于所述第一壳体的部分贴合于所述柔性屏幕的底部，因此，所述支撑带可以用于实现对所述柔性屏幕的底部支撑。并且，由于所述支撑带的底部设置有伸缩杆，所述伸缩杆可以用于支撑所述支撑带，提高所述支撑带对于所述柔性屏幕的支撑强度。这样，既可以避免所述柔性屏幕发生局部变形，而且，在所述柔性屏幕受到按压的情况下，还可以避免所述柔性屏幕发生晃动，有利于在所述柔性屏幕上进行触控操作。
