具体的，所述横梁21左右两端各有1个旋转轴C1和C2,第一连杆220的一端通过旋转轴C1和横梁左端连接，第二连杆221的一端通过旋转轴C2和横梁右端连接；其中第一连杆220的另一端通过第一连接件222与第三连杆224的一端连接,第二连杆221的另一端通过第二连接件223与第四连杆225的一端连接；所述第三连杆224的另一端通过第一滑动槽230中的旋转轴B1与位于支撑架23的腹板另一面的推杆组件24连接，所述第四连杆225的另一端通过第二滑动槽231中的旋转轴B2与位于支撑架的腹板另一面的推杆组件24连接。

请继续参阅图4，所述推杆组件24包括，动力推杆240、第一从动推杆241、第二从动推杆242以及第三从动推杆243；
所述动力推杆240固定设置在所述支撑架23上并与所述第二从动推杆242和第三从动推杆243的一端连接；
所述第二从动推杆242的另一端与所述第一从动推杆241的一端连接；
所述第一从动推杆241和第三从动推杆243的另一端分别连接所述连杆组件22。

其中，旋转轴A1、A2、A3、A4为固定不动的轴，与其连接的部件只能绕它做旋转运动，与旋转轴B1、B2连接的部件在做旋转运动的同时还可沿支撑架的腹板上的第一滑动槽和第二滑动槽做左右直线运动，旋转轴C1、C2、C3、C4、C5、C6、C7和C8除转动外，还可跟随连杆做位移，旋转轴A2-C6，C5-C1，A3-C8，C7-C2的中心距相同。
请参阅图6，下面对升降机构第一具体应用实施例的工作过程做进一步描述：
所述推杆组件24是动力源，动力推杆240可以通过电动、气动、液压等驱动，对于具体动力方式本公开不做限定，动力推杆240产生动力推动与旋转轴C4连接的第二从动推杆242和第三从动推杆243，使第二从动推杆242绕旋转轴A1点做向右的圆弧位移，第三从动推杆243向右做直线运动，同时与第二从动推杆242连接的旋转轴C3推动第一从动推杆241向左做直线运动，第三从动推杆243和第一从动推杆241推动旋转轴B2、B1分别向右、向左滑动，以推动第四连杆225绕A3点逆时针转动，第三连杆224绕A2点顺时针转动，第四连杆225拉动了第二连杆221顺时针绕旋转轴C2转动；第三连杆224拉动了第一连杆220逆时针绕旋转轴C1转动，这样就形成了第四连杆225与第二连杆221的折叠，以及连杆224与连杆220的折叠动态趋势，从而带动了横梁21的下降，当然图6中所示动力推杆240仅伸出部分，如将旋转轴C4推到设计的最右端，第四连杆225与第二连杆221，第三连杆224与第一连杆220完全折叠，带动横梁下降到最底端。可以想到的是旋转轴C4在非设计最左端的情况下，动力推杆240拉动旋转轴C4向左运动时，根据连杆联动的原理，带动横梁21做上升的运动。

具体的，第一动力推杆2406与第三连杆224在旋转轴B1处连接，第二动力推杆2407与第四连杆225在旋转轴B2处连接，第一动力推杆2406产生推力推动第三连杆 224向左移动，第二动力推杆2407产生推力推动第四连杆225向右移动，从而使得第四连杆225拉动了第二连杆221顺时针绕旋转轴C2转动；第三连杆224拉动了第一连杆220逆时针绕旋转轴C1转动，这样就形成了第四连杆225与第二连杆221的折叠，以及连杆224与连杆220的折叠动态趋势，从而带动了横梁21的下降。对于驱动连杆组件22控制柔性显示屏10上升的控制过程由于第一种实施方式已经做出说明，故在此不做赘述。
请参阅图10和图11，所述卷屏机构30包括：卷轴31、第一轴座32、第二轴座33、第一卷簧34、第二卷簧35以及限位轴36；
所述卷轴31设置在第一轴座32和第二轴座33的中间并与所述柔性显示屏10的底端相连接，所述第一轴座32和第二轴座33对称设置在所述支撑架23上；
所述第一卷簧34和第二卷簧35的一端分别与第一轴座32和第二轴座33连接，所述第一卷簧34和第二卷簧35的另一端分别与所述卷轴31的两端连接；
所述限位轴36平行设置在所述卷轴31的斜上方，所述限位轴36的两端分别与第一轴座32和第二轴座33连接。
在本实施例中，在所述支撑架23的腹板上对称安装有卷屏机构30的第一轴座32和第二轴座33，在第一轴座32和第二轴座33中间安装有卷轴31，卷轴的柱面与柔性显示屏10的底端连接，卷轴31两端的直径较小的阶梯轴的柱面分别连接有第一卷簧34和第二卷簧35的一端，所述第一卷簧和第二卷簧的另一端连接在第一轴座32和第二轴座33上，通过两个卷簧提供的预紧力来带动柔性显示屏10卷曲或释放，预紧力可通过卷簧连接的时候调整卷曲圈数来调节，需要说明的是，卷轴31与第一轴座32和第二轴座33的连接为可自由转动的连接方式，对于具体的连接方式本公开不做限定。
具体的，当升降机构带动柔性显示屏执行上升动作时，升降机构20驱动横梁21带动柔性显示屏10上端向上动作，柔性显示屏10下端部分带动卷轴31转动，被卷轴31卷曲的柔性显示屏10屏体得到释放，与此同时和卷轴31两端的阶梯轴连接的第一卷簧34和第二卷簧35受到卷轴31的扭转应力而使得第一卷簧34和第二卷簧35变得越来越紧，直到柔性显示屏10升至预设的最高高度；进一步，当升降机构20带动柔性显示屏10执行下降动作时，升降机构20驱动横梁21带动柔性显示屏10上端向下动作，卷屏机构30中的第一卷簧34和第二卷簧35的预紧力得到释放，带动卷轴31转动，柔性显示屏10下端部分随着卷轴31的转动而被卷起。在柔性显示屏10屏体卷曲到最底端时，可通过调节第一卷簧34和第二卷簧35的卷簧力，通过两个卷簧与两个轴座固定时卷簧 的缠绕圈数来调节卷簧的反向弹力，使卷轴31保持一定的卷曲屏的力，其中，所述限位轴36通过平行设置在所述卷轴31的斜上方，可便于在柔性显示屏10伸出时限制屏体的前后位置。
值得一提的是，请参阅图12，所述卷轴31柱面非正圆柱面，所述卷轴31沿轴线方向有一台阶，所述台阶厚度与所述柔性显示屏10厚度一致，所述柔性显示屏10屏体下端固定在台阶下，与台阶形成平缓的柱面。
进一步的，所述卷曲式显示装置还可应用到智能终端中，如图13所示；
在本实施例中，由于传统的智能终端显示屏是无法卷曲的，也无相应的卷屏机构技术，例如，人工智能物联网(AIOT)技术的发展和产品兴起，副屏显示AIOT相关状态信息的需求也越来越多，通过上述卷曲式显示装置可形成对柔性显示屏屏体的升降以及卷曲的同时进行，通过控制推杆组件的推位来控制柔性显示屏的升降高度，不同的高度可以对应不同的应用场景，例如将柔性显示屏屏体只升起三分之一时，可做为AIOT产品显示终端来显示相关信息，当柔性显示屏屏体升至全尺寸时展现大屏的使用功能。
基于上述的半导体的卷曲式显示装置，本公开还提供了一种智能终端。所述智能终端包括上述的卷曲式显示装置。应理解的是，所述智能终端当然还包括其他现有结构，故在此不做赘述。
本公开提供了一种卷曲式显示装置及智能终端，所述卷曲式显示装置包括柔性显示屏、与所述柔性显示屏的顶端相连接的升降机构以及与所述柔性显示屏的底端相连接的卷屏机构；所述升降机构用于带动所述柔性显示屏上升或下降；所述卷屏机构用于在所述升降机构带动所述柔性显示屏上升时将所述柔性显示屏展开，或者在所述升降机构带动所述柔性显示屏下降时将所述柔性显示屏卷起；从而实现了屏幕的升降和卷曲，不再受限于显示屏幕自身的体积，大大减小了显示屏幕所占的空间，克服了传统显示装置不便携的问题，为用户带来了便利。
可以理解的是，对本领域普通技术人员来说，可以根据本公开的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本公开所附的权利要求的保护范围。
