请参阅图1-5，本申请实施方式提供一种弯折组件10。弯折组件10包括转轴组件12、弹性件16与壳板14，弹性件16连接壳板14与转轴组件12。转轴组件12能够在展开状态与弯折状态之间切换。在展开状态向弯折状态切换时，转轴组件12与壳板14能够相对靠近移动。在弯折状态向展开状态切换时，转轴组件12与壳板14能够相对远离移动。弹性件16被配置成在转轴组件12在弯折状态向展开状态切换时，驱动壳板14与转轴组件12相对远离移动。
弯折组件10在弯折状态和展开状态之间来回切换时，通过弹性件16的伸缩产生的驱动力来驱动转轴组件12与壳板14发生相对位移，来抵消转轴组件12弯折时在弯折处弧长的变化，从而避免了对安装在弯折组件10的柔性显示屏24拉伸破坏，保证了柔性显示屏24的使用寿命。同时，也可使转轴组件12在展开状态时，柔性显示屏24能够平铺。
进一步地，弹性件16可在当弯折组件10弯折过程不顺畅时提供推拉力，使设置在弯折组件10上的柔性显示屏组件20避免翘起，并在弯折组件10弯折与展平过程中提供推力，推动壳板14运动，使展平过程顺畅，从而保持壳板14的平稳以避免柔性显示屏组件20翘起的问题。
具体地，请参阅图3，转轴组件12处于展开状态时，转轴组件12与壳板14之间的间隔距离为L，请结合图10和11，在转轴组件处于弯折状态时，转轴组件12与壳板14发生相对靠近移动，使得L减少成为L1，L的减少可为柔性显示屏24的弯折提供了额外的空间，使弯折组件10在弯折时，无需将柔性显示屏24进行拉伸，进而保证了柔性显示屏24的使用寿命。
在图1-4的实施方式中，弹性件16呈V型，弹性件16的一末端连接壳板14，另一末端连接转轴组件12。
具体的说，弹性件16的V形各个端处设置有定位部分，可通过螺丝、铆钉等方式穿过定位部分或以焊接方式以将弹性件16固定于预定的位置。优选的，选择螺丝固定方式，具备较高的固定效果并且拆卸方便，实施难度较低，操作方便灵活，可以降低成本。
进一步地，弹性件16的一末端转动或固定连接壳板14，另一末端转动或固定连接转轴组件12。
具体的说，弹性件16的两末端分别固定连接壳板14和转轴组件12时，弹性件16的安装方式较简单；弹性件16的两末端分别转动连接壳板14和转轴组件12时，弹性件16驱动壳板14和转轴组件12时受到的阻力较少。因此，可根据实际情况对弹性件16与壳板14及 转轴组件12的连接方式进行选择。当然，弹性件16与壳板14的连接方式可以与弹性件16与转轴组件12的连接方式相同或不同。
更具体地，在本实施方式中，第一板142和第一连接转轴122之间连接有两个弹性件16，第二板144与第二连接转轴124之间连接有两个弹性件16。这样在弯折组件10从弯折状态向展开状态切换时，第一板142和第二板144的移动更顺序。
另外，转轴组件12开设有容置槽17，弹性件16部分地位于容置槽17中。
具体的说，容置槽17呈长条状，一个容置槽17位于第一连接转轴122的外侧部121，两个第一滑轨132分别位于容置槽17的两端且第一滑轨132与容置槽17大致垂直；另一个容置槽17位于第二连接转轴122的外侧部121，两个第二滑轨134分别位于容置槽17的两端且第二滑轨134与容置槽17大致垂直。将弹性件16部分收容至容置槽17中可确保弹性件16的位置稳定性，避免弹性件16形变过程中发生期望外的位移，进而更稳定地驱动壳板14与转轴组件12的移动。
在某些实施方式中，弹性件16呈直线型，壳板14设置有第一定位柱(图未示)，转轴组件12设置有第二定位柱(图未示)，弹性件16套在第一定位柱与第二定位柱之间。
如此，弹性件16与转轴组件12、壳板14的位置关系稳定，可提供较好的推拉力以确保转轴组件12与壳板14之间的相对位移运动。
请参阅图5，在某些实施方式中，弹性件16呈直线型，转轴组件12设置有定位柱18，壳板14设置有定位座146，定位柱18一端可嵌在定位座146内，弹性件16套设在定位柱18。
弹性件16的直线型指的是弹性件16处于自然状态下的外观，具体的说，弹性件16可为圆柱形的压缩弹簧，是承受轴压力的螺旋弹簧，压缩弹簧的圈之间存在一定的间隙，当受到外载荷时弹性件16可收缩变形，存储形变时的能量以推动壳板14与转轴组件12之间发生相对位移变化。定位柱18与定位座146结合可将弹性件16的位置固定，使其按预设的方向发生形变，以得到想要的相对位移效果。
在一个例子中，弹性件16可采用弹簧钢制成。
弹簧钢是制造各类弹簧及其他弹性件16的专用合金钢，具有以下的综合性能，如力学性能、抗弹减性能、疲劳性能、淬透性、物理化学性能、优良的冶金质量、良好的表面质量、精确的外形和尺寸等。
在一个例子中，弹性件16可采用冷成形与热成形工艺制成。
冷成形与热成形工艺成熟，可生产制造质量较高、使用寿命较长的弹性件16。
在本申请实施方式中，弯折组件10包括呈片状的连接件13，连接件13滑动连接壳板14与转轴组件12。在展开状态向弯折状态切换时，转轴组件12与壳板14能够在连接件13的导向下相对靠近移动。在弯折状态向展开状态切换时，转轴组件12与壳板14能够在连接件13的导向下相对远离移动。
弯折组件10在弯折时，通过连接件13的导向作用来使转轴组件12与壳板14发生相对位移，来抵消弯折组件10弯折时在弯折处弧长的变化，从而避免了对安装在弯折组件10的柔性显示屏24拉伸破坏，保证了柔性显示屏24的使用寿命。同时，也可使转轴组件12在展开状态时，柔性显示屏24能够平铺。
请参阅6-8与图21，在本申请实施方式中，转轴组件12包括第一连接转轴122、第二连接转轴124与转向转轴结构126，壳板14包括第一板142与第二板144。第一连接转轴122与第二连接转轴124分别转动连接在转向转轴结构126相背两侧。连接件13包括第一滑轨132和第二滑轨134。第一滑轨132固定在第一连接转轴122且与第一板142滑动连接；第二滑轨134固定在第二连接转轴124且与第二板144滑动连接。
具体的说，第一连接转轴122和第二连接转轴124分别与转向转轴结构126转动连接的部分互相嵌合，并通过元件串接一起，在保证了转动连接稳固性的前提下也提高了空间利用率。如此转轴组件12的位置关系简单，便于组装成结构关系简单的弯折组件10，进而易于形成柔性显示装置100，以降低生产成本与制造难度。
具体地，本申请实施方式中，第一滑轨132呈板状，且第一滑轨132远离第一连接转轴122的一端且圆弧形，如此，一端为圆弧形的第一滑轨132可方便第一滑轨132与第一板142的装配。第二滑轨134的结构与第一滑轨132的结构相类似，在此不再展开。
第一滑轨132与第二滑轨134分别大致垂直于第一连接转轴122与第二连接转轴124，并可通过螺丝螺固、铆钉锚固与焊接方式与第一连接转轴122、第二连接转轴124固定连接。
第一滑轨132和第二滑轨134分别与第一连接转轴122和第二连接转轴124大致垂直可使第一滑轨132与第二滑轨134在第一板142与第二板144的滑动较为规整有序。螺丝螺固、铆钉铆固与焊接方式简单、工艺成熟且价格低廉，如此能够降低生产成本和生产难度，提高经济效益。
在其它实施方式中，第一滑轨132可固定在第一板142且与第一连接转轴122滑动连接。第二滑轨134可固定在第二板144且与第二连接转轴124滑动连接。
在本申请实施方式中，第一板142设置有第一滑座1422，第一滑轨132可滑动地穿设第一滑座1422。如此，方便第一滑轨132与第一板142的装配，有利用提高弯折组件10的 生产效率。
具体的，第一滑座1422可通过螺丝螺固、胶粘、焊接或一体成型的方式固定设置于第一板142上，第一滑座1422开设有第一滑槽，第一滑轨132穿过第一滑槽并与第一滑座1422滑动连接。
在图示的实施方式中，第一滑座1422大致为长方体形，当然，第一滑座1422的外形不限于长方体形，可以为带有供第一滑轨132滑动的滑动空间的正方形、圆形、梯形等规则或不规则的多边形，可在具体的实施方式中具体选择。
在其它实施方式中，当第一滑轨132与第一连接转轴122滑动连接时，第一连接转轴122设置有第一滑座1422，第一滑轨132可滑动地穿设第一滑座1422。
在本申请实施方式中，第二板144设置有第二滑座1442，第二滑轨134可滑动地穿设第二滑座1442。如此，方便第二滑轨134与第二板144的装配，有利用提高弯折组件10的生产效率。
具体的，第二滑座1442可通过螺丝螺固、胶粘、焊接或一体成型的方式固定设置于第二板144上，第二滑座1442开设有第二滑槽，第二滑轨134穿过第二滑槽并与第二滑座1442滑动连接。
在图示的实施方式中，第二滑座1442大致为长方体形，当然，第二滑座1442的外形不限于长方体形，可以为带有供第二滑轨134滑动的滑动空间的正方形、圆形、梯形等规则或不规则的多边形，可在具体的实施方式中具体选择。
在其它实施方式中，当第二滑轨134与第二连接转轴124滑动连接时，第二连接转轴124设置有第二滑座1442，第二滑轨134可滑动地穿设第二滑座1442。
第一滑轨132、第二滑轨134与第一滑座1422、第二滑座1442的数量各为两个，分别设置于预设的位置。例如，在图示的实施方式中，弯折组件10的平面形状大致呈矩形，第一滑轨132、第二滑轨134与第一滑座1422、第二滑座1442可分别设置在靠近弯折组件10的长侧边缘的位置，这样的好处是，靠近弯折组件10的中间部分可留有空间以安置其它元件或结构。
当然，第一滑轨132、第二滑轨134与第一滑座1422、第二滑座1442的数量不仅限于两个，可以为一个、三个、四个等多个，在保证质量与弯折组件10弯折过程顺畅的前提下，选择具体的数量。本申请实施方式选择两个以满足最基本的滑动与连接的稳定性。
在本申请实施方式中，第一连接转轴122、转向转轴结构126与第二连接转轴124同步转动。
如此，可保证弯折组件10的弯折过程流畅平缓，进而使柔性显示装置100的展平和弯折过程流畅，并提高了消费者的体验感。
具体地，请参阅图12与图13，转轴组件12包括同步齿轮模组128，同步齿轮模组128包括第一齿轮组1282与第二齿轮组1284，第一齿轮组1282转动连接第一连接转轴122与转向转轴结构126，第二齿轮组1284转动连接第二连接转轴124与转向转轴结构126。如此，通过齿轮结构来实现第一连接转轴122、转向转轴结构126与第二连接转轴124的同步转动，结构简单可靠且成本低廉。
请进一步参阅图15，第一齿轮组1282包括两个第一齿轮128a、第二齿轮128b、支架128c与定位杆128d。两个第一齿轮128a与第二齿轮128b外形大致为圆柱体，两个第一齿轮128a间隔并与第二齿轮128b相互啮合，两个第一齿轮128a的转动轴垂直于支架128c底面，第二齿轮128b的转动轴垂直于支架128c底面，第一齿轮128a的转动轴垂直于第二齿轮128b的转动轴。支架128c的另一面垂直固定设有定位杆128d，定位杆128d穿设并串联第一连接转轴122与转向转轴结构126。第一齿轮128a和第二齿轮128b均为斜齿轮。
另外，第一齿轮组1282的数量是两个，分别设置在转向转轴结构126的两端。这样使得第一齿轮组1282与转向转轴结构126的同步转动更平稳。
第二齿轮组1284的结构和位置与第一齿轮组1282的结构和位置相类似，在此不再详细展开。
在本申请实施方式中，转向转轴结构126包括第一转轴1262、第二转轴1264与第三转轴1266，第一转轴1262与第三转轴1266分别转动连接在第二转轴1264相背两侧，第一齿轮组1282安装在第一转轴1262的一端，第二齿轮组1284安装在第三转轴1266的一端。如此，三个转轴可满足绝大部分的弯折组件10弯折角度要求。
具体地说，两个第一齿轮组1282分别安装第一转轴1262的两端，两个第二齿轮组1284分别安装在第三转轴1266的两端。
当然，转向转轴结构126的具体实施方式并不限于上述讨论的实施方式，而可根据需求设置。例如，在某些实施方式中，可以采用更多的转轴数量，例如，采用二个转轴或四个、五个转轴的多转轴结构形成转向转轴结构126，以提供不同的弯折角度与更平滑的弯折组件10弯折效果。可以理解，更少的转轴可使转向转轴结构126的结构简单，成本低；更多的转轴可使转向转轴结构126的弯折角度更多样化。
在一个例子中，转轴组件12可采用马氏体不锈钢制成。也就是说，第一连接转轴122、第二连接转轴124、第一转轴1262、第二转轴1264与第三转轴1266都可采用马氏体不锈钢 制成。
请参阅图18与图19，在本申请实施方式中，转轴组件12在处于展开状态时的平面形状大致呈矩形。
如此，转轴组件12的形状规整，方便形成形状规整的弯折组件10，从而方便支撑形状规整的柔性显示屏组件，进而形成形状规整的柔性显示装置100。当然，转轴组件12的形状并不限制上面讨论的实施方式，而可以在其他实施方式中根据需求设置。
请参阅图9-11，在某些实施方式中，转轴组件12的弯折角度为0-180度。当弯折角度为0度时，第一连接转轴122和第二连接转轴124、转向转轴结构126位于同一平面。当弯折角度大于0度时，如弯折角度为90度(如图10)或180度(如图11)时，转向转轴结构126弯折，第一连接转轴122和第二连接转轴124基本平行设置。
另外，可以通过在第一连接转轴122、第二连接转轴124与转向转轴结构126连接处设置反转限制结构(图未示)，从而可以避免转轴组件12反向转动，例如可以避免在完全展开或者说0度的状态下继续往展开方向弯折，从而避免误操作损坏弯折组件10甚至损坏柔性显示屏组件20。
在某些实施方式中，同步齿轮模组128包括第三齿轮组1286，第三齿轮组1286安装在第二转轴1264的一端且转动连接第一齿轮组1282与第二齿轮组1284。
可以理解，第三齿轮组1286设置于第一齿轮组1282与第二齿轮组1284之间，第一齿轮组1282与第二齿轮组1284间隔，且在本实施方式中，第一齿轮组1282、第二齿轮组1284与第三齿轮组1286各为两个一组，共两组，分别设置于转轴组件12的两端。第一齿轮组1282、第二齿轮组1284与第三齿轮组1286转动连接的部分存在一定的阻尼，以保证转轴组件12的整体弯折同步进行，即转动任何一个齿轮，可带动其他所有的齿轮共同转动，同时转轴组件12也进行弯折，最后带动弯折组件10的弯折或展平。
请参阅图14，本实施方式中，第三齿轮组1286包括两个第三齿轮128e，两个第三齿轮128e与第三转轴1264垂直转动设置，呈现为一高一低并相互啮合的位置关系。同样的，两个第三齿轮128e外形大致为圆柱体，两个第三齿轮128e的转动范围为0-360度，可以理解，两个第三齿轮128e的转动范围是绕自身中心轴转动的角度即两个第三齿轮128e可自身周转。第三齿轮128e可为斜齿轮。
在某些实施方式中，进一步的，可以通过设置第一连接转轴122、第二连接转轴124与转向转轴结构126转动连接处干涉程度，即第一齿轮组1282、第二齿轮组1284与第三齿轮组1286转动连接的部分的阻尼大小，从而设置转动连接处的转动摩擦力，使得转轴组件12 处于任意角度时，转动摩擦力大于弯折组件10的转动部分的重力，从而可以在外力作用下弯折或展开后固定在当前状态。
请参阅图16-20，在某些实施方式中，同步齿轮模组128可省略第三齿轮组1286，其他位置与连接关系不变，可同样实现弯折组件10以第二转轴1264为中心弯折，第一连接转轴122与第二连接转轴124同步弯折，弯折组件10的弯折角度仍可为0-180度，并且通过设置第一齿轮128a与第二齿轮128b之间的阻尼，弯折组件10在可弯折的角度内可任意停止。
在本申请实施方式中，弹性件16的形变方向与连接件13的滑动方向平行。如此，可保证转轴组件12和壳板14相对位移时，弯折组件10的平稳性。
具体地，当弯折组件10进行弯折或者展平运动时，弹性件16形变以产生力并作用于转轴组件12和壳板上，使转轴组件12和壳板发生相对位移，同时，连接件13的滑动可导向转轴组件12和壳体14的相对位移，因而弹性件16的形变方向与连接件13的滑动方向平行，或者可以理解为同向。
请参阅图14与图21，在本申请实施方式中，壳板14包括与转轴组件12相对的第一侧部148，转轴组件12包括与壳板14相对的第二侧部121，所述第一侧部148形成有第一导向结构1482，第二侧部121开设有第二导向结构1212，第一导向结构1482与第二导向结构1212配合连接并导向壳板14与转轴组件12的相对移动。
具体的说，第一导向结构1482和第二导向结构1212均呈可互相卡合连接的梳齿状结构，且梳齿之间可发生相对位移，即壳板14与转轴组件12之间可相对位移，梳齿的相嵌卡合有较好的导向效果，壳板14与转轴组件12之间的相对位移也较为平缓，不易发生偏移。
在本申请实施方式中，第一板142与第一连接转轴122相对的第一侧部148形成有第一导向结构1482，第二板124与第二连接转轴124相对的第一侧部148形成有第一导向结构1482；第一连接转轴122与第一板142相对的第二侧部121形成有第二导向结构1212，第二连接转轴124与第二板144相对的第二侧部121形成有第二导向结构1212。
在一个例子中，壳板14采用金属或塑料制成。如此，壳板14的材料选择多样化，有利于降低弯折组件10的成本。
请参阅图1-3，本申请的实施方式提供一种柔性显示装置100，柔性显示装置100包括上述任一实施方式的弯折组件10和固定设置在弯折组件10上的柔性显示屏组件20。
将柔性显示屏组件20设置于弯折组件10上形成的柔性显示装置100可避免柔性显示屏24被弯折拉伸而损坏的情况，有着较长的使用寿命和较高的产品质量。
在本申请实施方式中，柔性显示屏组件20包括柔性支撑板22和柔性显示屏24，柔性 支撑板22与弯折组件10固定连接，柔性显示屏24贴合于柔性支撑板22与弯折组件10相背的一面上。
柔性支撑板22与柔性显示屏24贴合可以让柔性支撑板22更好的保护柔性显示屏24，既平整美观又具备高防护性。
在某些实施方式中，柔性支撑板22采用钛合金、不锈钢、碳纤维复合材料或凯夫拉制成。
以上材料强度高、刚性好、密度小、质量轻、热强度高、抗蚀性好，作为柔性支撑板22的材料比较适宜。
请参阅图3，在某些实施方式中，柔性支撑板22通过多个紧固件26穿设柔性支撑板22而固定在弯折组件10上。
具体地，紧固件26为螺丝，柔性支撑板22设有凸起222，凸起222上设有多个第一通孔224。请参阅图14，第二转轴1264对应凸起222设有凹槽15，凹槽15内设有多个第二通孔152，凸起222与凹槽15可相互嵌合定位。紧固件26穿设第一通孔224与第二通孔152以将柔性支撑板22锁固于转轴组件12上。进一步地，为了提高稳定性，柔性支撑板22与壳板14之间可通过螺固、铆固、双面胶或胶水粘接等方式固定。螺固、胶粘方式实施简单、工艺成熟且价格低廉，如此能够降低生产成本和生产难度，提高经济效益。
在某些实施方式中，柔性显示屏24包括OLED显示屏。
OLED显示屏同时具备自发光有机电激发光二极管，有着不需背光源、对比度高、厚度薄、视角广、反应速度快等优点，而且可用于挠曲性面板、使用温度范围广、构造及制程较简单。
在某些实施方式中，柔性显示装置100包括软胶圈30，软胶圈30包覆在柔性支撑板22与柔性显示屏24的外边缘。
软胶圈30由塑料通过注塑形成，常温下手感较软，具有良好的热稳定性和电绝缘性，能够有效保护柔性显示屏24与柔性支撑板22的边缘部分。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
