在本实施例中，请参照图2和图3，控制组件23容置于壳体1中。具体的，将控制组件23设置于卷轴21的腔体213中，进一步利用了腔体213的空间，使得整个自动卷绕组件2的结构较为紧凑，从而进一步优化了柔性显示装置100的结构。
一种实施方式中，请参照图2和图3，控制组件23包括按键231、主板232和电源233，按键231滑动设置于按键孔11a即外部结构中即且伸入第一开口211，主板232和电源233位于腔体213中，转动件22电连接于主板232，按键231切换电源233与主板232之间的通断，以控制转动件22的转动部221的转动状态。当然，在其它实施例中，控制组件还可以包括主板、接收器和发射器，主板电连接于转动件，接收器电连接于主板，发射器无线连接于接收器，发射器能够发射信号给接收器，接收器将接收到的信号发送给控制器，使得控制器控制转动件的转动状态，该控制组件无需设置物理按键，而可以直接通过智能设备上的WIFI模块、蓝牙模块或者红外模块来自动控制柔性显示设备的卷绕。可以理解的，只要主板与转动件之间能够有电信号的传输，主板和/或接收器可以位于卷轴的腔体中，还可以位于卷轴的外部。
可以理解的，请参照图2，按键231包括按压部231a和固定部231b，按压部231a为圆形，按压部231a容置于按键孔11a中，固定部231b为板状，固定部231b上设置有主板232，固定部231b固定连接于按压部231a，其中固定部231b与按压部231a垂直连接，且固定部231b朝着远离按压部231a的方向延伸，即按键231的截面形成T形，通过按压按压部231a带动固定部231b滑行， 主板232固定设置于固定部231b上，该按键231结构使得主板232能够固定于固定部231b上并伸入第一开口211，利于转动件22焊接于主板232上且与转动件22电连接，使得转动件22和控制组件23的结构较为紧凑，优化了控制组件23的结构。当然，在其它实施例中，按键231还可以为柱状，主板232直接粘接于按键231上，主板232与按键231形成T形。
其中，请参照图2和图4，电源233与固定部231b的端部之间设置间距，此时电源233与主板232为断开的状态，即电源233无法为主板232供电，进而主板232停止控制转动件22的转动部221转动，而当按压部231a带动固定部231b上的主板232滑动至与电源233接触时，电源233与主板232电连接，即电源233为主板232供电，进而主板232控制转动件22的转动部221转动，使得卷轴21能够随之转动。可以理解的，电源233与主板232之间的导通形式可以为：电源233为电池，主板232设置电极，当按键231沿着靠近电源233的方向滑动时，电源233与主板232通过电极电连接；或者主板232设置弹片，当按键231沿着靠近电源233的方向滑动时，电源233与主板232通过弹片电连接。
进一步的，请参照图4，壳体1还包括与按键孔11a相背设置的固定端，固定端设置固定孔，电源233远离主板232的一端嵌设于固定孔中。其中，固定端即封闭的第二端12，第二端12凸设环形凸起12a形成固定孔，电池形式的电源233远离主板232的一端嵌设于该固定孔中，以实现电源233在壳体1中的固定，进一步优化柔性显示装置100的结构。
上述的自动卷绕组件2通过转动件22与卷轴21之间传动连接，以带动卷轴21转动，并通过控制组件23控制转动件22的转动状态，能够通过对控制组件23上面电信号的控制来实现自动卷绕组件2的自动卷绕，操作较便捷。
在本实施例中，请参照图1和图4，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。具体的，柔性屏组件3具有相背设置的卷绕端S1和拉伸端S2，卷绕端S1固定于卷轴21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，其中当要使柔性显示装置100处于收缩状态时，则按压按键231，使主板232与电源233导通，主板232控制转动件22的转动部221转动，转动部221带动卷轴 21转动，从而将柔性屏组件3的拉伸端S2与壳体1的缝隙14之间的距离逐渐减少，而使柔性屏组件3自动卷绕于卷轴21上。而使得需要展开柔性屏组件3时，则直接拉住拉伸端S2即可将展开柔性屏组件3。
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。具体的，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，将柔性屏组件3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100的可靠性。
当柔性显示装置100需要收缩起来时，则按压按键231，使主板232与电源233导通，主板232控制转动件22的转动部221转动，转动部221带动卷轴21转动，从而将柔性屏组件3的拉伸端S2与壳体1的缝隙14之间的距离逐渐减少，而使柔性屏组件3自动卷绕于卷轴21上。而使得需要展开柔性屏组件3时，则直接拉住拉伸端S2即可将展开柔性屏组件3。
本发明提供的自动卷绕组件2通过转动件22与卷轴21之间传动连接，以带动卷轴21转动，并通过控制组件23控制转动件22的转动状态，能够通过对控制组件23上面电信号的控制来实现自动卷绕组件2的自动卷绕，操作较便捷。
本发明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通过自动卷绕组件2使得 柔性屏组件3能够自动在壳体1中进行卷绕，便于柔性显示装置100的收纳，从而提供了一种显示界面较大，能够自动收纳的柔性显示装置100。
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。
