本申请实施例提供一种柔性显示装置，用以缓解现有的柔性显示装置中柔性显示屏占用空间较大的技术问题。
图1为本申请实施例提供的柔性显示装置的爆炸示意图，图2为本申请实施例提供的柔性显示装置的组装结构示意图，结合图1和图2所示，本申请的柔性显示装置包括：
壳体10，与壳体10固定设置的第一支撑构件50，与第一支撑构件50相对滑动设置的第二支撑构件60，设置在壳体10中且与第二支撑构件60连接的传动机构30；
柔性显示屏40，铺设在第一支撑构件50和第二支撑构件60的一侧，且柔性显示屏40的第一端41与第二支撑构件60远离第一支撑构件50的一端连接，柔性显示屏40的第二端42与传动机构30连接；
当第一支撑构件50与第二支撑构件60相对滑动时，柔性显示屏40的两端在传动机构30作用下，在相同时间内保持相同运动距离的移动。
壳体10包括底板13、第一侧板11和第二侧板12，底板13包括矩形的底面、以及分别与底面相对设置的两侧边连接的第一弯折部和第二弯折部，其中第一弯折部为平板，与底面的一条侧边垂直连接，第二弯折部与底面的另一侧边连接，且朝向第一弯折部的方向弯曲，形成空心的半圆柱状，第一弯折部和第二弯折部与底面为一体成型结构，形成底板13。第一侧板11和第二侧板12可以是与底板13一体成型，也可以是独立成型后再安装在底板13上，第一侧板11和第二侧板12均为平板且分别与底板13相对的另外两个侧边垂直连接，因此第一侧板11和第二侧板12相互平行。底板13、第一侧板11和第二侧板12相互连接，使得壳体10内部形成容纳腔。
第一支撑构件50、第二支撑构件60和传动机构30均安装在壳体10内部，其中第一支撑构件50与壳体10固定安装，第二支撑构件60和传动机构30均与壳体10活动安装，第一支撑构件50和第二支撑构件60相对滑动设置，即第二支撑构件60沿底板13与第一侧板11相交边的长度方向来回滑动。
传动机构30设置在壳体10中，且与第二支撑构件60连接，在第二支撑构件60与第一支撑构件50相对滑动时，传动机构30中的部分构件与第二支撑构件60之间可以同时沿滑动方向逐渐靠近，也可以同时沿滑动方向逐渐远离，其中滑动方向为底板13与第一侧板11相交边的长度方向，在图1中指水平方向。通过传动机构30的控制作用，柔性显示屏40的两端可以在相同时间内保持相同运动距离的移动，且两端的移动的方向相反。
柔性显示屏40通常为OLED显示屏，具有可折叠、可卷曲的功能，柔性显示屏40铺设在第一支撑构件50和第二支撑构件60的一侧，第一端41固定在第二支撑构件60远离第一支撑构件50的一侧，第二端42与传动机构30连接。其中，第一端41可以与第二支撑构件60的上表面固定，柔性显示屏40的上表面可以显示画面，第二端42与传动机构30连接，第二端42不用于显示画面，除了第二端42之间的区域可以显示画面，在收卷过程中该部分区域可以根据拉伸程度的不同，位于壳体10外或位于壳体10内。
根据使用者的不同需求，柔性显示屏40可以处于不同的状态，其中第一状态指大屏显示状态，第二状态为小屏显示状态，在两种状态下，柔性显示屏40的第一端41均位于柔性显示装置的外表面，均可以用于显示画面。
当柔性显示屏40处于第一状态时，如图4和图5所示，第一支撑构件50与第二支撑构件60同时向相互远离的方向滑动，柔性显示屏40的第一端41随第二支撑构件60一起滑动，柔性显示屏40的第二端42随传动机构30一起滑动，两端在水平方向上逐渐远离，且在相同时间内保持相同运动距离的移动。柔性显示屏40位于壳体10内的部分随着第二支撑构件60和传动机构30的共同作用逐渐被拉出壳体10外，该部分区域可用于显示画面，被拉出壳体10后，第一端41和拉出壳体10的部分区域共同显示画面。当柔性显示屏40的可拉伸区域均被拉出壳体10时，柔性显示装置可实现大屏显示，此时柔性显示屏40的显示面积为最大显示面积。
当柔性显示屏40处于第二状态时，如图6和图7所示，第一支撑构件50与第二支撑构件60同时向相互靠近的方向滑动，柔性显示屏40的第一端41随第二支撑构件60一起滑动，柔性显示屏40的第二端42随传动机构30一起滑动，两端在水平方向上逐渐靠近，且在相同时间内保持相同运动距离的移动。柔性显示屏40位于壳体10外的部分随着第二支撑构件60和传动机构30的共同作用逐渐被收进壳体10中，此时，第一端41和未被拉进壳体10的部分区域共同显示画面。当柔性显示屏40的可拉伸区域均被拉进壳体10时，柔性显示装置可实现小屏显示，此时柔性显示屏40的显示面积为初始显示面积。
通过上述设置方式，柔性显示装置可以在第一状态和第二状态进行切换，在柔性显示屏40需要大屏显示时，将需要显示的区域从壳体10中拉出，使柔性显示装置的显示面积增加，显示的内容可以更加丰富，在柔性显示屏40需要小屏显示时，将不需要显示的区域收进壳体10中，使得柔性显示装置尺寸较小，占用空间较小，便于携带。本申请的柔性显示装置可以灵活控制柔性显示屏40的显示面积，且壳体10也可以保护内部的柔性显示屏40不受损失。此外，在柔性显示屏40被收进和拉出壳体10的过程中，柔性显示屏40的两端在传动机构30作用下，在相同时间内均保持相同运动距离的移动，因此同一时刻柔性显示屏40的第一端41从壳体10内部拉出部分的长度，与第二端42向壳体10外部送出部分的长度相等，且拉出与送出的速度相等，因此可以使得柔性显示屏40向外伸展与向内收缩时不会受到较大拉扯，从而对柔性显示屏40形成保护作用，延长了柔性显示屏40的使用寿命。
在一种实施例中，传动机构30包括第一拉伸构件31、第二拉伸构件32、滑动构件34以及传动构件33，第一拉伸构件31与第二支撑构件60固定，第二拉伸构件32与滑动构件34固定，滑动构件34与壳体10相对滑动设置，传动构件33与壳体10连接，柔性显示屏40的第二端42与滑动构件34连接。
第一拉伸构件31位于第二拉伸构件32远离底板11的一侧，传动构件33位于第一拉伸构件31和第二拉伸构件32之间。滑动构件34的两侧均活动安装在第一侧板11和第二侧板12的内壁上，第二支撑构件60和滑动构件34均可在壳体10中沿滑动方向来回滑动。传动构件33工作时，可以带动第一拉伸构件31和第二拉伸构件32同时沿滑动方向反向移动。根据柔性显示屏40的状态不同，传动构件33带动第一拉伸构件31和第二拉伸构件32移动的方向也不同，可以使两者沿滑动方向逐渐靠近，也可以使两者沿滑动方向逐渐远离。
当柔性显示屏40处于第一状态时，如图4和图5所示，传动构件33带动第一拉伸构件31和第二拉伸构件32向相互远离的方向移动，由于第二支撑构件60与第一拉伸构件31固定，滑动构件34与第二拉伸构件32固定，第一拉伸构件31带动固定在第二支撑构件60上的柔性显示屏40的第一端41，第二拉伸构件32带动固定在滑动构件34上的柔性显示屏的第二端42，将柔性显示屏40的至少部分区域拉出壳体10。
当柔性显示屏40处于第二状态时，如图6和图7所示，传动构件33带动第一拉伸构件31和第二拉伸构件32向相互靠近的方向移动，第一拉伸构件31带动固定在第二支撑构件60上的柔性显示屏40的第一端41，第二拉伸构件32带动固定在滑动构件34上的柔性显示屏的第二端42，将柔性显示屏40的至少部分区域拉进壳体10。
在柔性显示屏40被拉出或拉进壳体10的过程中，传动构件33可在任意时刻控制第一拉伸构件31和第二拉伸构件32停止移动，因此可以控制柔性显示装置在初始显示面积和最大显示面积之间选取任意大小的面积进行显示，较为灵活。
第一支撑构件50固定在壳体10中，因此传动机构30中第一拉伸构件31和第二拉伸构件32沿滑动方向同时反向移动时，第一支撑构件50保持不动，第二支撑构件60沿靠近第一支撑构件50的方向滑动，或沿远离第一支撑构件50的方向滑动，来带动柔性显示屏40的至少部分区域收进和拉出壳体10，为使第二支撑构件60和滑动构件34滑动时始终与滑动方向保持一致，需要在第一侧板11和第二侧板12上设置限位结构。
如图1和图3所示，第一侧板11的内壁和第二侧板12的内壁上均设置有第一滑槽121、第二滑槽122和传动槽123，第一滑槽121和第二滑槽122均与底板13平行，传动槽123设置在第一滑槽121和第二滑槽122之间，第二支撑构件60的两侧活动安装在第一滑槽121中，滑动构件34的两侧活动安装在第二滑槽122中，传动构件33的两端安装在传动槽123中。
具体地，第二支撑构件60为平板结构，且与底板13平行，柔性显示屏40的第一端41固定在第二支撑构件60的上表面上，因此第二支撑构件60对柔性显示屏40起到支撑作用，第二支撑构件60包括设置在两侧的第一滑块311，第一滑块311嵌在第一滑槽121中，可沿着第一滑槽121的长度方向来回滑动；滑动构件34也为平板结构，且与底板13平行，柔性显示屏40的第二端42与滑动构件34的上表面或下表面固定，滑动构件34包括设置在两侧的第二滑块321，第二滑块321活动嵌在第二滑槽122中，可沿着第二滑槽122的长度方向来回滑动。
在滑动过程中，由于第二支撑构件60和滑动构件34均沿着第一滑槽121和第二滑槽122的长度方向进行滑动，因此可以保证壳体10外部的柔性显示屏40也沿着该方向拉进和拉出壳体10，在观看柔性显示屏40上的画面时，不会出现屏面倾斜或凹凸不平的情况，保证了观看效果。
如图1和图2所示，第二支撑构件60与滑动构件34相对设置，第一拉伸构件31包括固定在第二支撑构件60靠近滑动构件34一侧的第一齿条，第二拉伸构件32包括固定在滑动构件34靠近第二支撑构件60一侧的第二齿条，传动构件33包括齿轮331和穿过齿轮331中心孔锁的齿轮销332，齿轮销332安装在壳体10上，齿轮331与第一齿条和第二齿条均啮合。
齿轮销332活动安装在传动槽123中，可以使齿轮331围绕自身轴线顺时针或逆时针转动，齿轮331与第一齿条和第二齿条均啮合，齿轮331、第一齿条和第二齿条的模数和齿距均相等。因此，第一齿条与齿轮331相互配合形成齿轮副，第二齿条与齿轮331也形成齿轮副。
如图4和图6所示，在柔性显示装置切换第一状态和第二状态时，通过齿轮331的转动来带动第一拉伸构件31和第二拉伸构件32移动，而齿轮331的动力来自于柔性显示装置的驱动机构（图未示出），在柔性显示屏40处于第一状态时，驱动机构驱动齿轮331沿第一方向转动，齿轮331通过与第一齿条啮合带动第一拉伸构件31向远离第二拉伸构件32的方向移动，通过与第二齿条啮合带动第二拉伸构件32向远离第一拉伸构件31的方向移动，柔性显示屏40处于第二状态时，驱动机构驱动齿轮331沿第二方向转动，齿轮331通过与第一齿条啮合带动第一拉伸构件31向靠近第二拉伸构件32的方向移动，通过与第二齿条啮合带动第二拉伸构件32向靠近第一拉伸构件31的方向移动，其中第一方向为顺时针方向或逆时针方向中的一者，第二方向为顺时针方向或逆时针方向中的另一者。
驱动机构可以是与齿轮331连接的电机或者减速设备，利用电机或者减速设备驱动齿轮331可使整个运动系统由电信号控制，使用者仅需要通过按键给电机传达电信号，就能带动整个运动系统运动，使本申请的柔性显示设备在收缩与拉伸两种显示状态下切换。
由于齿轮331与第一齿条和第二齿条均啮合，因此第二支撑构件60和滑动构件34的移动距离始终保持大小相等、方向相反，即柔性显示屏40在被拉出壳体10时，第二支撑构件60从壳体10内部拉出部分的长度，与滑动构件34向壳体10外部送出部分的长度相等，且拉出与送出的速度相等，因此可以使得柔性显示屏40向外伸展与向内收缩时不会受到较大拉扯，从而对柔性显示屏40形成保护作用，延长了柔性显示屏40的使用寿命。
齿轮331通过齿轮销332活动安装在传动槽123中，通过自身的转动带动第一拉伸构件31和第二拉伸构件32反向移动，为使第一拉伸构件31和第二拉伸构件32可以移动的距离尽可能长，传动槽123设置在第一侧板11的内壁和第二侧板12的内壁上的中间位置，即齿轮331位于柔性显示装置的中间位置。
在一种实施例中，齿轮331的模数为0.25毫米至5毫米。
第一齿条设置在第二支撑构件60靠近滑动构件34的一侧，第二齿条设置在滑动构件34靠近第二支撑构件60的一侧，通过传动构件33中齿轮331的转动带动齿条移动。第一齿条、第二齿条和传动构件33的设置方式有多种。
在一种实施例中，第一齿条整面设置在第二支撑构件60靠近滑动构件34的一侧，第二齿条整面设置在滑动构件34靠近第二支撑构件60的一侧，齿轮销332贯穿齿轮331的两端，分别与第一侧板11和第二侧板12上的传动槽123活动安装，齿轮331的宽度小于或等于第一侧板11和第二侧板12的间距。
在一种实施例中，如图1所示，第一拉伸构件31包括分别靠近第一侧板11和第二侧板12的两个第一齿条，第二拉伸构件32包括分别靠近第一侧板11和第二侧板12的两个第二齿条，传动构件33包括第一传动构件和第二传动构件，第一传动机构中齿轮331与靠近第一侧板11的第一齿条和第二齿条啮合，齿轮销332安装在第一侧板11内壁，第二传动机构中齿轮331与靠近第二侧板12的第一齿条和第二齿条啮合，齿轮销332安装在第二侧板12内壁。
具体地，第二支撑构件60的底面设置有相互平行的两个第一齿条，两个第一齿条分别靠近第一侧板11和第二侧板12，两个第一齿条完全相同，滑动构件34的顶面设置有相互平行的两个第二齿条，两个第二齿条分别靠近第一侧板11和第二侧板12，且与两个第一齿条对应设置，两个第二齿条也完全相同，传动构件33包括相互分离的第一传动构件和第二传动构件，第一传动构件中齿轮销332活动安装在第一侧板11上的传动槽123中，第二传动构件中齿轮销332活动安装在第二侧板12上的传动槽123中，第一传动构件中齿轮331与靠近第一侧板11的第一齿条和第二齿条均啮合，第二传动构件中齿轮331与靠近第二侧板12的第一齿条和第二齿条均啮合，且两个传动构件中两个齿轮331完全相同，两个齿轮销332也完全相同。
本申请的柔性显示装置，通过齿轮331、齿轮销332、第一齿条和第二齿条的相互配合，使得柔性显示屏40可在第一状态和第二状态切换，且柔性显示屏40拉出和收进壳体10过程中不会受到较大的拉扯作用，整个传动机构30结构简单，无需过多复杂的设计，因此在柔性显示装置内部占用的空间较小，进一步使得柔性显示装置整体体积较小，更加方便携带。
由于第二支撑构件60和滑动构件34均为平板结构，为防止柔性显示屏40在与两者固定时，柔性显示屏40呈现与第二支撑构件60和滑动构件34的边缘垂直的情况而刮伤，在第二支撑构件60的一侧设置导向构件70，柔性显示屏40绕过导向构件70，可使柔性显示屏40的第一端41和第二端42较为平滑地转接。
导向构件70的两端安装在第一侧板11和第二侧板12上，导向构件70用于提供柔性显示屏40滑动过程中的方向引导，使得柔性显示屏40滑动更加顺利，导向构件70可以固定安装或活动安装在第一侧板11和第二侧板12上，在本实施例中，导向构件70的安装方式为活动安装。
在一种实施例中，导向构件70为滚轮，滚轮的两个端面活动安装在第一侧板11和第二侧板12上。具体地，可以在第一侧板11和第二侧板12的内壁、以及滚轮的两个端面中，其中一者上设置圆形凸起124，另一者上设置圆形凹槽21，圆形凸起124嵌在圆形凹槽21内。即，可以如图1和图3所示，在第一侧板11和第二侧板12的内壁上均设置圆形凸起124，在滚轮的两个端面上均设置圆形凹槽21，然后将两个圆形凸起124卡接在两个圆形凹槽21内，也可以在第一侧板11和第二侧板12的内壁上均设置圆形凹槽21，在滚轮的两个端面上均设置圆形凸起124，然后也将两个圆形凸起124卡接在两个圆形凹槽21内，两者方式均可。其中，圆形凸起124和圆形凹槽21的圆心均落在滚轮的轴线上，因此滚轮可以绕着自身轴线转动。当柔性显示屏40被拉出和收进壳体10时，滚轮可以随着柔性显示屏40的移动方向转动，使得柔性显示屏40拉伸时的阻力更小，拉动更加容易，柔性显示屏40的底面不会产生较大的摩擦，延长了使用寿命。
如图1和图2所示，第一支撑构件50的两侧固定安装在第一侧板11和第二侧板12的内壁上，柔性显示屏40的第二端42与滑动构件34连接。第一侧板11和第二侧板12的内壁上均形成有卡槽125，第一支撑构件50的两端卡接在卡槽125中，第一支撑构件50与第一侧板11和第二侧板12之间不可相对移动或相对转动。
柔性显示屏40的第一端41与第二支撑构件60的上表面固定，第二端42与滑动构件34固定，在柔性显示屏40逐渐被拉出壳体10外时，壳体10外部的柔性显示屏40一部分随着第二支撑构件60移动，另一部分由第一支撑构件50提供支撑，为保证拉出过程中柔性显示屏40处于壳体10外的部分都能得到支撑，本申请将第一支撑构件50和第二支撑构件60设置成具有重叠部分，即拉伸过程中第一支撑构件50和第二支撑构件60不会出现相互分离状态。
在一种实施例中，如图1和图2所示，第一支撑构件50和第二支撑构件60中，其中一者的上表面设置有多个间隔设置的凹槽601，凹槽601的长度方向与滑动方向相同，另一者包括多个间隔设置的梳齿602，梳齿602与凹槽601一一对应且嵌在凹槽601中。
本实施例以第二支撑构件60设置有凹槽601，第一支撑构件50设置有梳齿602为例，凹槽601的长度方向与滑动方向相同，梳齿602与凹槽601一一对应，且沿凹槽601的长度方向嵌在凹槽601中。当柔性显示屏40随着第一拉伸构件31的移动被拉出壳体10时，由于第一支撑构件50与第一侧板11和第二侧板12固定，保持不动，梳齿602随着第一拉伸构件31的移动逐渐向远离凹槽601的方向滑动，梳齿602嵌在凹槽601中的长度逐渐变短，而当柔性显示屏40随着第一拉伸构件31的移动被收进壳体10时，梳齿602随着第一拉伸构件31的移动逐渐向靠近凹槽601的方向滑动，梳齿602嵌在凹槽601中的长度逐渐变长。
在一种实施例中，梳齿602的长度小于或等于凹槽601的长度，这样在第一拉伸构件31移动至柔性显示屏40的显示面积为初始显示面积时，梳齿602在长度方向上完全嵌入凹槽601中，此时第一支撑构件50和第二支撑构件60相互配合，两者之间没有较大的间隙，在触碰柔性显示屏40时各部分均有支撑，提高了触控效果。此外，凹槽601的长度方向可以提供滑动方向的限位，使得柔性显示屏40在拉伸过程中受力均匀。
在一种实施例中，如图8所示，凹槽601的截面为倒梯形，梳齿602的截面为正梯形，梳齿602的顶面高度小于或等于凹槽601顶部开口的高度。凹槽601截面为倒梯形，即凹槽601为燕尾槽，凹槽601的底面面积大于顶部开口的面积，且梳齿602的顶面位于凹槽601的开口之下或与开口平齐，因此当梳齿602嵌在凹槽601中，凹槽601的顶部开口可以提供上下方向的限位，使整个梳齿602不能从凹槽601的开口穿过，从而可以防止第一支撑构件50的梳齿602向上翘起划伤柔性显示屏40。
在一种实施例中，多个凹槽601等间距设置，则相应地多个梳齿602也等间距设置，两者对柔性显示屏40提供的支撑比较均匀，支撑效果更好。
需要说明的是，本申请中第一支撑构件50和第二支撑构件60的结构和形状不限于此，其他可以在柔性显示屏40的至少部分区域拉出壳体10后，共同为柔性显示屏40提供支撑功能的第一支撑构件50和第二支撑构件60，均落入本申请的保护范围。
在一种实施例中，如图1和图2所示，第二支撑构件60远离第一支撑构件50的一端设置有朝向底板13的固定部，固定部形成实心的半圆柱形，包括半圆柱面、平面和相对设置的两个端面，其中在柔性显示屏40的显示区域等于初始显示面积时，固定部的平面与壳体10的第三侧板的外壁接触，可以阻断外部的杂质和灰尘进入壳体10内部对柔性显示屏40造成损失。
柔性显示屏40的第一端41通过第一粘结层固定在第二支撑构件60的上表面，第一粘结层的材料可以是光学胶。柔性显示屏的第二端42通过第二粘结层或夹紧构件固定在滑动构件34的上表面或下表面，第二粘结层的材料可以是光学胶，夹紧构件可以是夹板等。
由上述实施例可知，本申请提供的柔性显示装置，可以通过设置传动机构，使柔性显示装置的滑动方向上尺寸增大或减小，在拉伸过程中，通过齿轮、齿条等构件的配合，可以使原本收纳在壳体内部的柔性显示屏拉出至柔性显示装置的上表面，使柔性显示装置的显示尺寸增加，也可以通过相反的方向拉伸，将柔性显示装置上表面的部分显示柔性显示屏收纳进壳体内部，直至缩小至初始尺寸。通过上述设置方式，柔性显示装置可以在第一状态和第二状态进行切换，且柔性显示屏40拉出和收进壳体10过程中不会受到较大的拉扯作用，在柔性显示屏需要大屏显示时，将需要显示的区域从壳体中拉出，使柔性显示装置的显示面积增加，显示的内容可以更加丰富，在柔性显示屏需要小屏显示时，将不需要显示的区域收进壳体中，使得柔性显示装置尺寸较小，占用空间较小，便于携带。
根据以上实施例可知：
本申请提供一种柔性显示装置，包括壳体，与壳体固定设置的第一支撑构件，与第一支撑构件相对滑动设置的第二支撑构件，设置在所述壳体中且与所述第二支撑构件连接的传动机构和柔性显示屏；柔性显示屏铺设在所述第一支撑构件和所述第二支撑构件的一侧，且所述柔性显示屏的第一端与所述第二支撑构件远离所述第一支撑构件的一端连接，所述柔性显示屏的第二端与所述传动机构连接；当所述第一支撑构件与所述第二支撑构件相对滑动时，所述柔性显示屏的两端在所述传动机构作用下，在相同时间内保持相同运动距离的移动。通过上述设置方式，本申请的柔性显示装置可以在柔性显示屏需要大屏显示时，将需要显示的区域从壳体中拉出，使柔性显示装置的显示面积增加，显示的内容可以更加丰富，在柔性显示屏需要小屏显示时，将不需要显示的区域收进壳体中，使得柔性显示装置尺寸较小，占用空间较小，便于携带，柔性显示屏在拉出和收进壳体过程中，两端在相同时间内保持相同运动距离的移动，因此不会受到较大拉扯力，提高了柔性显示屏的使用寿命。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
