请参照图1和图2，为本发明提供的一种柔性显示装置100，柔性显示装置100包括壳体1、卷轴2、柔性屏组件3和报警组件4。柔性屏组件3卷绕于卷轴2上，卷轴2容置于壳体1中，柔性屏组件3能够经过壳体1的缝隙拉伸出壳体1的外部，在柔性屏组件3拉伸的过程，报警组件4能够对柔性屏组件3需要报警的拉伸长度进行报警，以使用户了解柔性屏组件3当前的拉伸状态。
在一实施例中，请参照图2，壳体1为内部为中空的柱体，壳体1的横截面为水滴状。壳体1的外部开设一个缝隙(未图示)，该缝隙为长条形，该缝隙连通了壳体1的内腔11b，以使得位于壳体1中的柔性屏组件3能够通过缝隙拉伸出壳体1的外部。可以理解的，壳体1的材质为金属。当然，在其它实施例中，壳体1还可以为笔状、圆柱状，等等。当然，在其它实施例中，壳体1的材质还可以为塑料，等等。
可以理解的，壳体1包括一个中空的筒体11和两个侧盖12，筒体11具有相背设置的两个开口端，两个侧盖12分别可拆卸的盖接于两个开口端上，以组成该壳体1。将壳体1设置为上述的可拆卸结构，便于壳体1内的部件例如卷轴2通过筒体11的开口端伸入壳体1的内腔11b中。当然，在其它实施例中，壳体1还可以为其它结构，比如筒体11上连接两个开口端的一部分侧壁可拆卸连接于筒体11上，即取下该部分的侧壁即可实现将壳体1内的部件容置于壳体1的内腔11b中，对应的，两个侧盖12可以分别固定连接于两个开口端上。
在一实施例中，请参照图2，卷轴2呈圆柱状，卷轴2容置于壳体1的内腔11b中，能够在壳体1的内腔11b中转动，使得卷绕在卷轴2上的柔性屏组件3受到外力拉伸时，卷轴2能够随着柔性屏组件3的拉伸而相应在壳体1中转动，以实现柔性屏组件3的拉伸。其中，卷轴2为筒体，由于卷轴2一般会占据壳体1的内腔11b的大部分面积，将卷轴2设置为中空的筒体，使得卷轴2的内部能够容置部件，以减少对壳体1的内腔11b的尺寸的需求，进一步优化了柔性屏组件3的结构。可以理解的，卷轴2的两端分别转动连接于两个侧盖12上。对应的，侧盖12上凸设环形凸起12a，一个侧盖12的环形凸起12a伸入筒体的一个开口中，使得卷轴2转动连接于两个侧盖12上。当然，在其它实施例中，卷轴2还可以设置实心的柱体。当然，在其它实施例中，壳体1的筒体11上还可以设置轴承座，卷轴2承载于轴承座上，实现卷轴2在壳体1中的转动。
在一实施例中，柔性屏组件3能够用于显示和触控。柔性屏组件3能够反复弯折且具有弹性。在一实施例中，柔性屏组件3具有相背设置的固定端S1和拉伸端S2、连接于固定端S1和拉伸端S2之间的两个侧边S3，固定端S1固定于卷轴2上，拉伸端S2位于壳体1的外部，便于通过拉伸拉伸端S2来将柔性屏组件3从壳体1中拉出来。
可以理解的，为了使得柔性屏组件3具有一定的刚性，不会太过于柔软而轻易变形，提高用户对柔性屏组件3操作的便捷性，柔性屏组件3包括柔性屏和柔性支撑件，柔性屏层叠贴覆于柔性支撑件上。在一实施例中，柔性支撑件通过薄钢片和硅胶混合注塑形成，使得柔性支撑件能够反复弯折且具有弹性。 柔性屏层叠贴覆于柔性支撑件上，当柔性屏组件3展开时，柔性屏组件3由于有柔性支撑件的支撑不会轻易变形，而能够固定在一定的形状。当然，在其它实施例中，柔性屏组件3还可以由柔性屏组成。或者，柔性支撑件能够用薄硅胶片来代替。
可以理解的，柔性屏组件3的厚度为5mm；或者，柔性屏组件3的厚度为6mm；或者，柔性屏组件3的厚度为5mm～6mm。发明人通过大量的实验发现，将柔性屏组的厚度限定在5mm～6mm，能够利于柔性屏组件3的卷绕，进一步提高柔性显示装置100100的可靠性。
在一实施例中，请参照图2和图3，报警组件4容置于壳体1中，报警组件4包括报警器42和电连接至报警器42的检测器41、43，检测器41、43检测柔性屏组件3的拉伸长度，当检测器41、43检测到柔性屏组件3拉伸至预设长度时，触发报警器42报警。
在一实施例中，报警器42可以为声音报警器；或者，报警器42可以为声光报警器；或者，报警器42可以为振动器。其中，该报警器42设置在电路板上，设置有报警器42的电路板固设于一个侧盖12上，且伸入卷轴2的内部，报警器42与检测器41、43之间为有线的电连接时，还可以在卷轴2的筒体11内部走线即所述报警器42与所述检测器41、43之间的电线位于卷轴2的内部，进一步优化了柔性屏组件3的结构。当然，在其它实施例中，报警器42还可以根据实际情况而相应设置，比如将报警器42放置于壳体1的其它位置。
在一实施例中，检测器41、43的结构有多种。检测器41、43与报警器42的配合，能够达到提醒用户，防止柔性屏组件3损伤的目的。
一种实施例中，请参照图3，检测器41包括发射器411和接收器412，发射器411设置于侧边S3，接收器412分别电连接于发射器411和报警器42，当柔性屏组件3拉伸至预设长度时，接收器412接收到发射器411发射的信号，报警器42报警。
在一实施例中，请参照图2和图3，由于发射器411设置在柔性屏组件3的侧边S3上，则柔性屏组件3拉伸时，发射器411会随着柔性屏组件3的侧边S3转动，当发射器411转动至一定位置时，其与接收器412之间的距离能够满足发射器411发射的信号能够给接收器412接收到，则接收器412将接收 到的信号发送给报警器42，报警器42上的电路板根据该信号发送报警信号，来触发报警42报警，以提醒用户柔性屏组件3当前的拉伸状况。可以理解的，接收器412的位置根据实际所需的报警位置而相应设置，在柔性屏组件3拉伸的过程中，接收器412越晚接收到发射器411的信号，则报警器42发出报警信号时，柔性屏组件3当前的拉伸长度越长，越能够准确提醒用户柔性屏组件3快拉伸到位的状态，避免对其进一步拉伸而损坏柔性屏组件3。上述的报警组件4完全采用电信号的传输，对报警组件4中的部件的位置的局限较小。
一种实施例中，请参照图2和图4，检测器43位于卷轴2的外部，检测器43在柔性屏组件3拉伸的过程中检测与限位部3a之间的间距以获得柔性屏组件3拉伸的长度，当检测器43检测到柔性屏组件3拉伸至预设长度时，报警器42报警。可以理解的，检测器43与限位部3a的间距根据实际情况而相应设置，比如检测器43与限位部3a的间距可以为零，或者检测器43与限位部3a的间距可以为一定距离。
其中，限位部3a为凸设于侧边S3上的限位凸起。
可以理解的，请参照图4和图5，检测器43包括外壳431、开关组件432和弹簧433，外壳431位于卷轴2的外部，外壳431具有一个伸出孔和连通伸出孔的容置腔431a，开关组件432和弹簧433位于容置腔431a中，开关组件432包括开关4321和开关帽4322，弹簧433弹性连接于开关4321和开关帽4322之间，开关4321的端部经一个伸出孔伸出，当柔性屏组件3拉伸至限位部3a抵靠于开关4321的端部，且限位部3a推动开关4321直至开关4321与开关帽4322电连接时，报警器42报警。在一实施例中，外壳431固定设置在侧盖12上，且位于卷轴2的外部，外壳431为矩形的壳体1，其内部设置容置腔431a，并且该容置腔431a相背设置的两个开口分别位于壳体1的上下端即形成两个伸出孔。开关4321的两端分别伸出两个伸出孔，在柔性屏组件3拉伸的过程中，限位部3a随着柔性屏组件3的拉伸而相应转动，直至限位部3a被拉伸至抵靠于开关4321的端部时，此时若继续拉伸柔性屏组件3，则限位部3a克服弹簧433的弹性力而推动开关4321滑动直至与开关4321与开关帽4322电连接，此时报警器42报警，告知用户柔性屏组件3以拉伸到位，已不能够继续拉伸。该检测器43很限位部3a的配合不仅使得柔性屏组件3在快拉伸到到位时，通 过弹性件的阻尼感告知用柔性屏组件3的当前拉伸状态，而且在柔性屏组件3处于完全拉伸状态时，由于开关4321已与开关帽4322电连接，使得限位部3a无法继续前行，而阻止柔性屏组件3进行进一步拉伸，能够对柔性屏组件3起到较佳的保护作用，从而提高柔性显示装置100的可靠性。当然，在其它实施例中，检测器为压力传感器，当柔性屏组件拉伸至限位部抵靠于检测器上时，报警器报警。
可以理解的，检测器41、43的数量可以为一个，或者两个，等等。当检测器41、43的数量为两个时，两个检测器41、43可以同时电连接于一个报警器42，并且对应的，两个发射器411分别设置在两个侧边S3上，或者侧边S3上分别设置两个限位部3a以与两个检测器41、43配合。
当柔性显示装置100需要拉伸时，拉动拉伸端S2，使得柔性屏组件3经缝隙伸出壳体1的外部，当柔性屏组件3快拉伸到位时，检测器41、43检测到，报警器42报警告知用户当前的柔性屏组件3的拉伸状态，避免对柔性屏组件3进一步拉伸而损坏柔性屏组件3。
本发明实施例提供的柔性显示装置100将柔性屏组件3设置容置于壳体1中，由于柔性屏组件3能够在外力作用下发生柔性变形，即呈弯曲或展平的状态，使得柔性显示装置100的壳体1受柔性屏组件3的尺寸的影响较小，即柔性显示装置100中容置柔性屏组件3的壳体1的尺寸可以较小，但是柔性显示装置100却可以具有较大的显示面积，并且柔性显示装置100通过在壳体1中设置报警组件4，使得柔性屏组件3处于完全拉伸状态时，用户能够得知而不会进一步拉伸柔性屏组件3而损坏柔性屏组件3，从而提高了柔性显示装置100的可靠性。
以上是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
