然后，将所述卷筒30放置于所述第一壳体21内，使所述卷筒30可转动地收容于所述收容槽217内。其中，所述卷筒30两端的轴承37分别安装于所述收容槽217相对两端的所述第一定位筋214的第一定位槽2141内，所述轴承37远离挡板的一端的端面抵接于所述第一定位筋214，所述卷筒30相对两端的端面位于所述第一定位筋214远离所述收容槽217的一侧，设置于所述卷筒30其中一端面上的所述按键电路板40可转动地收容于所述第一安装部213内，设置于所述卷筒30另一端的所述通孔3333内的导电滑环36通过所述第二连接器362与所述第二安装部215内的所述充电电路板38电性连接。套接于所述驱动轴325末端的所述固定件50位于所述第一安装部213内，所述第一安装部213的定位柱2134分别卡入所述固定件50的定位孔54内，防止所述固定件50沿所述驱动轴325的轴向移动。
最后，将所述第二壳体22盖合于所述第一壳体21上，所述第一壳体21的两个所述第一定位筋214的第一定位槽2141与所述第二壳体22的两个所述第二定位筋224的第二定位槽2241共同围成能够卡固所述两个轴承37的轴承座，所述轴承37的外圈抵接于所述轴承座的环形槽面上。所述第一连接部223覆盖于所述第一安装部213上，所述第二连接部225覆盖于所述第二安装部215上，所述第二安装部215的连接柱2152插入所述第二连接部225的连接口2252内，若干螺钉分别穿过所述连接口2252的通孔及连接块2233的通孔2235并螺接于连接柱2152的连接孔2153及所述第一安装部213的连接孔2133。
其中，穿过所述通孔2235的螺钉先穿过所述固定件50的通孔55而后螺接于所述第一安装部213的连接孔2133，所述第二壳体22的连接块2233压覆于所述固定件50的固定片上，从而将所述固定件50固定于所述第一壳体21的第一安装部213内。
综上，所述收卷装置200中，所述卷筒30相对的两端与所述壳体20相对的两端之间分别通过一所述轴承37连接，所述卷筒30能够通过所述两个轴承37而在所述壳体20内转动。所述柔性键盘100的柔性输入屏10设置于所述卷筒30上，所述柔性输入屏10能够跟随所述卷筒30的转动而收卷于所述壳体20内，方便用户携带。
进一步的，所述收卷装置200还包括设置于所述壳体20一端的按键组件，所述按键组件用于控制所述卷筒30的转动。具体的，所述按键组件设置于所述第一壳体21一端的所述第一安装部213内，所述按键组件包括可转动地收容于所述第一安装部213内的所述按键电路板40，通过触发所述按键电路板40上的所述按键41能够控制所述驱动件32的转动，进而控制所述卷筒30的转动。
请参阅图3、图17和图18，所述按键组件还包括活动地设置于所述壳体20上的键帽60。具体的，所述键帽60活动地设置于所述第一壳体21靠近所述第一安装部213的一端的端部，所述键帽60设置于所述端板2131的中部安装孔内。
所述键帽60包括按压部61及凸设于所述按压部61朝向所述按键电路板40一侧的键帽主体62，所述键帽主体62沿所述卷筒30的轴向可滑动地设置于所述第一壳体21内。所述键帽60沿所述卷筒30的轴向开设有收容腔63，所述收容腔63开设于所述键帽主体62中部。所述键帽主体62还开设有连通所述收容腔63的导向槽621，所述键帽主体62的外壁周面上设置有凸条622。本实施例中，所述凸条622设置于所述键帽主体62相对的上下两侧的外壁周面上。
进一步的，所述按键组件还包括可迫使所述键帽60复位的弹性件，按压所述键帽60使所述弹性件弹性变形，松开所述键帽60后所述弹性件弹性复位驱动所述键帽60复位。本实施例中，所述弹性件为弹簧65。
其中，所述固定件50位于所述按键电路板40与所述键帽主体62之间，所述弹性件弹性抵顶于所述键帽主体62与所述固定件50之间，所述弹性件的一端收容于所述收容腔63内，所述弹性件的另一端抵接于所述固定件50。
优选的，所述按压部61和/或所述固定件50上可以设置供所述弹性件进行安装的辅助结构。本实施例中，如图3和图17中所示，所述按压部61上于所述收容腔63内凸设有一凸柱611，所述弹性件，即弹簧65收容于所述收容腔63的一端能够套接于所述凸柱611上，保证所述弹簧65安装更牢靠。
在其他实施例中，所述固定件50相对两侧的连接片52靠近所述连接柱51的位置可以分别开设一缺口，所述弹簧65抵接于所述固定件50的一端能够卡入两侧的缺口内，从而辅助所述弹簧65进行安装。
如图3和图16中所示，所述固定件50能收容于所述导向槽621与所述收容腔63构成的空间内。所述导向槽621沿所述卷筒30的轴向长度大于所述固定件50的宽度，所述键帽60可相对于所述按键电路板滑动。
从而，本申请中，按压并松开所述键帽60能够使所述键帽60与所述按键41接触与分离，用于触发所述按键41。
具体的，当按压所述按压部61时，所述键帽主体62朝所述按键电路板40滑动，所述键帽主体62与所述按键41接触；当松开所述按压部61时，在所述弹性件的弹力作用下，所述键帽主体62背离所述按键电路板40滑动，所述键帽主体62与所述按键41分离。
其中，如图13中所示，当所述键帽主体62背离所述按键电路板40滑动时，所述键帽主体62上的所述凸条622能抵接于所述壳体20上，所述键帽60停止滑动，防止所述键帽60脱离所述壳体20。具体的，在所述弹性件的弹力作用下，所述键帽主体62与所述按键41分离后，所述键帽60仍可背离按键电路板40滑动一些距离，直至所述凸条622抵接于所述端板2131朝向所述收容槽217一侧的定位台2132，所述键帽60复位停止滑动。
需要说明的是，所述弹性件具有一定的预压缩量，即所述键帽60复位后，所述弹性件仍存在 一定的弹性变形，以提供一定的弹力，保证所述键帽60未被按压时处于复位状态。
所述键帽主体62与所述按键41接触并分离后，能够触发所述按键41，使所述按键控制板40产生控制信号并传递给所述主板31，所述主板31根据接收到的所述控制信号控制所述驱动件32的转动。
具体的，在一些实施例中，当所述驱动件32处于停止状态时，按压并松开所述按压部61能触发所述按键41而控制所述驱动件32转动；在其他实施例中，当所述驱动件32处于转动状态时，按压并松开所述按压部61则能触发所述按键41而控制所述驱动件32停止。
优选的，所述驱动件32的控制逻辑设置为双击模式，即，所述驱动件32处于停止状态时，连续两次按压并松开所述按压部61能够控制所述驱动件32转动，再连续两次按压并松开所述按压部61则能够控制所述驱动件32停止。同理，所述驱动件32处于转动状态时，连续两次按压并松开所述按压部61能够控制所述驱动件32停止，再连续两次按压并松开所述按压部61则能够控制所述驱动件32转动。
本实施例中，所述驱动件32的控制逻辑设置为双击模式，能够避免误触所述键帽60而使所述驱动件32转动。
显然，在其他实施例中，所述驱动件32的控制逻辑可以设置为其他模式，例如单击模式，即单次按压并松开所述按压部61能够控制所述驱动件32转动或者停止。
本申请中，由于所述驱动件32固定于所述卷筒30内，所述驱动轴325的末端通过所述固定件50固定于所述壳体20上，因此，所述驱动件32的转动能带动所述卷筒30在所述壳体20内转动，所述按键41能够跟随所述卷筒30转动，而所述键帽主体62在触发所述按键41后即与所述按键41分离，可以避免所述按键41转动过程中产生磨损，提高了所述按键41的使用寿命。
进一步的，如图3和图17中所示，所述按键组件还包括一导光柱80，所述导光柱80嵌设于所述壳体20设置有所述键帽60的一端。具体的，所述导光柱80设置于所述第一壳体21靠近所述第一安装部213的一端的端部，所述导光柱80嵌设于所述端板2131的沉槽内，所述键帽60位于所述导光柱80内。
如图17和图19中所示，所述导光柱80包括环形的基体81以及凸设于所述基体81相对的两侧的嵌体82，所述键帽60远离所述按键电路板40的一端收容于所述基体81内，所述嵌体82的形状与所述端板2131的所述沉槽内的两个嵌入孔形状一致，所述嵌体82穿过所述第一壳体21靠近所述按键电路板40。所述导光柱80包括入光面83、出光面84和壁面。
其中，所述入光面83与所述按键电路板40上的背光源46对应，所述出光面84外露于所述端板2131的端部，所述壁面是指所述导光柱80除开所述入光面83和所述出光面84以外的其他面。
优选的，本实施例中，所述导光柱80采用具有导光性能的透明塑料，所述壁面部分喷涂有反光油漆。
从而，所述导光柱80在所述背光源46的照射下，所述出光面84能够发出均匀柔和的光，以起到指示灯的作用，用户可以直观的找到位于所述导光柱80内的所述键帽60，并且配合所述键帽60达到更加美观的效果。
