具体地,第一连接构件1311包括两个第一连接平面、一第二连接平面以及连接第二连接平面和两个第一连接平面的两个垂直面。一垂直面连接一第一连接平面和第二连接平面,另一垂直面连接另一第一连接平面和第二连接平面。两个第一连接平面对称地位于第二连接平面的两侧且与第二连接平面平行。第二连接构件1312包括连接台以及位于连接台一侧的凸耳。第一连接构件1311的中间具有第一连接孔1311a,即第二连接平面上设置有第一连接孔1311a。两组第一连接件131分别设置于两个第一固定槽110a中,且螺栓穿过第一连接孔1311a和第三连接孔110b以可拆卸固定连接第一连接件131和第一支撑框体110。同一第一连接构件1311的两个第一连接平面上均设置有第五连接孔,对应地,第二连接构件1312上设置有第六连接孔,螺栓穿过第五连接孔和第六连接孔以连接第二连接构件1312和第一连接构件1311。第二连接构件1312的凸耳上设置有第七连接孔,传动转轴的一端插入第七连接孔中以使一柱体转轴连接于第一支撑框体110。第三连接构件1321与第一连接构件1311相同,第四连接构件1322与第一连接构件1312相同,此处不作详述。第三连接构 件1321的中间具有第二连接孔1321a。两组第二连接件132分别设置于两个第二固定槽111a中,螺栓穿过第二连接孔1321a和第四连接孔111b以可拆卸固定连接第二连接件132和第二支撑框体111。
如图2和图5所示,转轴组件14包括第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144。第一柱体转轴141与第一支撑框体110转动连接。第四柱体转轴144与第二支撑框体111转动连接。第一柱体转轴141和第二柱体转轴142通过第一连杆145连接,第三柱体转轴143和第四柱体转轴144通过第二连杆146连接,第二柱体转轴142和第三柱体转轴143通过弹性连杆147连接,且设置于第二柱体转轴142上的第一齿轮1423和设置于第三柱体转轴143上的第二齿轮1433相互抵接。第二柱体转轴142和第三柱体转轴143之间还设置有弹性回复件148,弹性回复件148用于在折叠式显示装置100从外折叠态变为展平态时,在第三柱体转轴143的作用下将位于第二层的第二柱体转轴142拉回,以使得第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144并排设置。
第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144可以为单根柱体转轴。第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144中的每个柱体转轴也可以包括中空的转轴主体以及两个传动转轴,其中,一传动转轴的一端插入转轴主体一端的腔体中,另一传动转轴的一端插入转轴主体另一端的腔体中。
具体地,如图5和图6所示,图6为图1所示折叠式显示装置处于外弯折状态时转轴组件和连接组件的示意图。第一柱体转轴141包括中空的第一转轴主体1411以及分别插接于第一转轴主体1411两端的两个第一传动转轴1412。第二柱体转轴142包括中空的第二转轴主体1421以及分别插接于第二转轴主体1421两端的两个第二传动转轴1422。第三柱体转轴143包括中空的第三转轴主体1431以及分别插接于第三转轴主体1431两端的两个第三传动转轴1432。第四柱体转轴144包括中空的第四转轴主体1441和分别插接于第四转轴主体1441两端的两个第四传动转轴1442。

在本实施例中,每个转轴主体包括第一平面、第二平面、第三平面以及弧形面。弧形面和第一平面相对,第二平面和第三平面相对,第二平面连接第一平面和弧形面的一端,第三平面连接第一平面和弧形面的另一端。如图7所示,其为沿垂直于图5所示第一转轴主体长度方向的截面的示意图。第一转轴主体1411包括第一平面1411a、第二平面1411b、第三平面1411c以及弧形面1411d。弧形面1411d和第一平面1411a相对,第二平面1411b和第三平面1411c相对,第二平面1411b连接第一平面1411a和弧形面1411d的一端,第三平面1411c连接第一平面1411a和弧形面1411d的另一端。第二转轴主体1421、第三转轴主体1431以及第四转轴主体1441与第一转轴主体1411相同,此处不作详述。相对于每个转轴主体为中空的圆柱体,该转轴主体为上述结构使得柱体转轴更容易由一层分为两层或由两层转化为一层。
折叠式显示装置处于展平态时,第一转轴主体1411、第二转轴主体1421、第三转轴主体1431以及第四转轴主体1441并排设置且相邻两个转轴主体相互接触。第一转轴主体1411的第一平面、第二转轴主体1421的弧形面、第三转轴主体1431的第一平面以及第四转轴主体1441的第一平面位于靠近金属片15的一侧,且与第一支撑框体110和第二支撑框体111共同支撑金属片15。

请参阅图8A和图8B,图8A为本申请第二实施例折叠式显示装置处于展平状态的截面示意图,图8B为本申请第二实施例折叠式显示装置处于外弯折状态的截面示意图。本申请第二实施例折叠式显示装置与图1所示折叠式显示装置基本相似,不同之处在于,第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144的第一转轴主体、第二转轴主体、第三转轴主体以及第四转轴主体均为中空的圆柱体,每个中空的圆柱体的半径均为r。
折叠式显示装置处于展平状态时,第一柱体转轴141、第二柱体转轴142、第三柱体转轴143以及第四柱体转轴144并排设置且相邻两个柱体转轴相接触。此时转轴组件对应的柔性显示面板的长度为A1B1,A1B1的长度大约为6r。
折叠式显示装置处于外折叠状态时,第一柱体转轴141、第三柱体转轴143以及第四柱体转轴144为第一层,第二柱体转轴142叠置于第三柱体转轴143上,此时转轴组件对应的柔性显示面板的长度为A1’B1’,A1’B1’的长度约为
即A1’B1’的长度约8.4r。
折叠式显示装置从展平状态和外弯折状态之间变化时,转轴组件对应的柔性显示面板的变化长度为2.4r。如图9所示,其为传统技术中半径为3r的单轴折叠式显示装置处于外折叠状态和展平状态时的 截面示意图。展平状态时,单个转轴对应的柔性显示面板的长度为AB,AB趋近于0(根据实际经验得到),弯折状态时,单个转轴对应的柔性显示面板的A’B’长度为3πr。即单个转轴对应的柔性显示面板在展平状态和外弯折状态之间变化时的变化长度约为3πr,即约9.42r。由此可知,相对于传统技术,本申请实施例折叠显示装置能明显避免柔性显示面板受过大应力作用而被拉伸。
请参阅图10A和图10B,图10A为本申请第三实施例折叠式显示装置处于展平状态的截面示意图,图10B为本申请第三实施例折叠式显示装置处于外弯折状态的截面示意图。本申请第三实施例折叠式显示装置与第一实施例折叠式显示装置基本相似,不同之处在于,转轴组件包括第一柱体转轴141、第二柱体转轴142、第三柱体转轴143、第四柱体转轴144、第五柱体转轴145以及第六柱体转轴146。第一柱体转轴141与第一支撑框体110转动连接,第六柱体转轴146与第二支撑框体111转动连接,第一柱体转轴141和第二柱体转轴142通过第一连杆转动连接,第二柱体转轴142与第三柱体转轴143通过第一弹性连杆转动连接,且设置于第二柱体转轴142上的第一齿轮(未示出)和设置于第三柱体转轴143上的第二齿轮(未示出)相互抵接,第五柱体转轴145与第六柱体转轴146通过第二连杆转动连接,第四柱体转轴144与第五柱体转轴145通过第二弹性连杆转动连接,且设置于第四柱体转轴144上的第三齿轮(未示出)和设置于第五柱体转轴145上的第四齿轮(未示出)相互抵接。第三柱体转轴143和第四柱体转轴144通过第三连杆转动连接。第二柱体转轴142和第三 柱体转轴143还通过第一弹性回复件连接,第四柱体转轴144和第五柱体转轴145还通过第二弹性回复件连接,第一弹性回复件和第二弹性回复件用于在折叠式显示装置100从外折叠态变为展平态时,第二柱体转轴142在第三柱体转轴143的作用下且第五柱体转轴145在第四柱体转轴144的作用下,将位于第二层的第二柱体转轴142和第五柱体转轴145拉回。另外,第一柱体转轴141、第二柱体转轴142、第三柱体转轴143、第四柱体转轴144、第五柱体转轴145以及第六柱体转轴146的转轴主体均为中空的圆柱体,每个中空的圆柱体的半径均为r。
折叠式显示装置处于展平状态时,第一柱体转轴141、第二柱体转轴142、第三柱体转轴143、第四柱体转轴144、第五柱体转轴145以及第六柱体转轴146并排设置。转轴组件对应的柔性显示面板的长度为A2B2,A2B2约为10r。
折叠式显示装置处于外折叠状态时,第一柱体转轴141、第三柱体转轴143、第四柱体转轴144以及第六柱体转轴146并排设置且相邻两个柱体转轴相接触以构成第一层,第二柱体转轴142和第五柱体转轴145并排设置以构成第二层且分别位于第三柱体转轴143和第四柱体转轴144上。此时,转轴组件对应的柔性显示面板的长度为A2’B2’,A2’B2’约为
即A2’B2’约为10.4r。
折叠式显示装置从展平状态和外弯折状态之间变化时,转轴组件对应的柔性显示面板的变化长度为0.4r。相对于传统技术中使用半径为3r的单个转轴时,单个转轴对应的柔性显示面板在展平状态和外 弯折状态之间变化时的变化长度约为3πr,即约9.42r。由此可知,相对于传统技术,本申请实施例折叠显示装置能明显避免柔性显示面板受过大应力作用而被拉伸。
