技术领域
本发明涉及一种折叠机构，特别涉及一种用于柔性显示屏的折叠机构。
背景技术
柔性显示器是由柔软的材料制成并且可弯曲的显示装置。具体地，柔性显示屏(flexible display)使用了磷光性OLED技术，这种技术的特点是，低功耗，体积小，直接可视柔性。因此，由于柔性显示屏轻薄、不易碎、可弯曲以及可佩戴等优点，柔性显示屏受到越来越多的关注。
然而，当柔性显示屏在弯曲或折叠状态下极易产生皱褶，严重地影响了其显示效果以及使用寿命，是本技术领域的一大难题。

在附图中，相同的部件使用相同的附图标记。附图并未按照实际的比例。
具体实施方式
下面将结合附图对本发明作进一步说明。
如图1至图4所示，本发明提供一种用于柔性显示屏的折叠机构，其主要包括：限位机构10、承载部30以及可形变的支撑件40。在本文中，请根据图2来定义“上”、“下”、“左”和“右”，例如可形变的支撑件40的“上侧”和“下侧”分别与限位机构10连接，并且可形变的支撑件40的“左侧”和“右侧”分别与承载部30连接。
其中，两个承载部30之间固定有所述的可形变的支撑件40，并且在可形变的支撑件40以及其两端的至少部分承载部30上固定有柔性显示屏20。具体地，特别如图3和图4所示，所述承载部30朝向彼此的一端分别设置有用于放置可形变的支撑件40的凹槽310，使得当可形变的支撑件40放置在承载部30的凹槽310内时，可形变的支撑件40与承载部30的朝向柔性显示屏20的表面是平齐的，这样柔性显示屏20可以平铺在可形变的支撑件40以及其两端的至少部分承载部30上。
所述可形变的支撑件40由具有记忆功能的、高韧性、高弹性的材料制成，例如由记忆合金制成，具体地，例如钛镍合金、非晶金属、无机材料等，使得可形变的支撑件40可以以任意形状弯曲并保持为该形状。
所述可形变的支撑件40可以为片状结构、框状结构等，只要保证可形变的支撑件40能够与承载部30固定并且保证可形变的支撑件40与承载部30的朝向柔性显示屏20的表面是平齐的即可。
所述可形变的支撑件40还可以由具有铰链替代，特别是具有记忆功能的、 高韧性、高弹性的铰链。
下面来介绍限位机构10，特别如图1、图3和图4所示。所述限位机构10的数量为两个，并且相对地布置于所述可形变的支撑件40的上、下两侧，即两个限位机构10位于可形变的支撑件40的相对两端，而两个承载部30位于可形变的支撑件40的相对的另外两端。
每个限位机构10上均设置有两条弯曲的、对称的、预定轨迹的滑轨110，具体地，所述滑轨110呈弧状，并且朝向限位机构10的中心方向弯曲。
对应地，所述承载部30朝向彼此的一端的上、下两侧分别设置有滑块320，所述滑块320能够在限位机构10的对应的滑轨110中滑动。需要注意的是，滑块320与可形变的支撑件40的端部可以是对齐的，这样当可形变的支撑件40在弯曲时，根据可形变的支撑件40弯曲的半径便于计算滑轨110的轨迹。如图3所示，当柔性显示屏20处于平展状态时，滑块320均位于滑轨110的最底端；如图4所示，当柔性显示屏20处于最大折叠状态时，滑块320均位于滑轨110的最顶端，此时可形变的支撑件40弯曲呈圆弧状，并具有半径R。
当两个承载部30的滑块320之间的距离为L，这代表可形变的支撑件40的宽度也为L。那么，有以下公式(请见图5)：
L＝πR＝θr
其中，θ为滑轨110上任意一点与y轴的夹角，r为所述任意一点所在的圆弧的半径。
而任意一滑块320的轨迹点D(Dx,Dy)满足以下条件：
Dx＝r*sin(θ)，Dy＝r–r*cos(θ)
由此，即可得到滑轨110的轨迹。
优选地，所述滑块320可以为转动轴，并且所述转动轴上可以设置弹性件(例如弹簧或弹片)，使得转动轴在转动时可以随意角度止滑或自动闭合。
在折叠过程中，所述滑轨110的预定轨迹需要保证承载部30始终与可形变的支撑件40相切，这样在弯曲或折叠过程中，柔性显示屏20不用承受承载部30的压力，可以减少柔性显示屏20的内应力，由此避免柔性显示屏出现皱褶，并且可延长柔性显示屏20的使用寿命。
本发明的工作原理是：
当需要折叠柔性显示屏20时，只需将两块承载部30沿着靠近彼此的方向扳动，承载部30上的滑块320将沿着限位机构10的滑轨110移动，直至滑块320运动到滑轨110的最顶端，此时柔性显示屏20呈折叠状态，此为限位机构10为柔性显示屏20提供的最大限度的弯曲程度。
当需要平展柔性显示屏20时，只需将两块承载部30沿着远离彼此的方向扳动，承载部30上的滑块320将沿着限位机构10的滑轨110移动，直至滑块320运动到滑轨110的最底端，此时柔性显示屏20呈平展状态，此为限位机构10为柔性显示屏20提供的最大限度的平展状态，即，可以使得柔性显示屏20呈水平放置。
综上所述，本发明提供一种用于柔性显示屏的折叠机构，其有益效果在于：能够实现柔性显示屏弯曲、折叠、平展的功能，此外限位机构具备导轨及限位的功能，使承载部按照预定的轨迹向内弯曲，实现无皱褶的弯曲及折叠功能。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，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。本发明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。
