在介绍本申请的技术方案之前，再详细介绍下相关技术中的技术问题。
在柔性电子设备中，转轴套件是控制柔性电子设备转动的重要结构件之一。转轴套件的种类有很多种，通常以转轴套件包括支撑柔性屏的板数量来进行命名，例如四板转轴套件，五板转轴套件。当板的数量较多时，例如五板转轴套件，相邻的两个板之间会存在一定的缝隙，而五板转轴套件相对于四板转轴套件会增加一个缝隙，增加一个断差，从而影响柔性屏的表面效果。这是由于该缝隙首先会导致对应该处的柔性屏没有刚性支撑。其次缝隙也会影响相邻两块板之间的齐平度，导致柔性屏在不同处存在高度差，最终影响柔性屏的表面效果。而对于四板转轴套件来说，相关技术中的四板转轴套件结构复杂，零部件较多，而每个两件之间由于都会存在装配公差，这将会导致转轴套件中累积的空隙增加，增加由此带来的尺寸链的大小，增加跌落窜动量，降低转轴套件的品质。
鉴于此，本申请提供了一种转轴套件，通过相对两侧的转动板与固定板构成四板转轴套件，并利用第一转动件与第一支架的配合，第二转动件与第二支架的配合，形成结构简单的转轴套件结构。
请参考图1-图2，图1为本申请一实施方式中转轴套件的截面示意图。图2为本申请一实施方式中转轴套件的部分立体结构示意图。本实施方式提供了一种转轴套件1，所述转轴套件1包括转轴组件10，所述转轴组件10包括保护壳11、以及设于所述保护壳11上的第一支架12，所述第一支架12内设有第一收容空间13。设于所述转轴组件10相对两侧的转动组件20，每个所述转动组件20包括转动板21、以及设于所述转动板21相对两端且连接所述转动板21的第一转动件22与第二转动件23，至少部分所述第一转动件22设于所述第一收容空间13内且可相对所述第一支架12进行旋转。设于所述转轴组件10相对两侧的壳体组件30，每个所述壳体组件30包括相连接的第二支架32与固定板31，所述第二支架32内设有第二收容空间33，至少部分所述第二转动件23设于所述第二收容空间33内且可相对所述第二支架32进行旋转。
本申请提供的转轴组件10包括保护壳11，其中，保护壳11首先用于承载第一支架12，将第一支架12固定在保护壳11上，其次保护壳11可以遮挡第一支架12，以免第一支架12露出，防止第一支架12损坏。
本申请还包括设于转轴组件10相对两侧的转动组件20，图2仅示意出了一侧的转动组件20的结构，另一侧的转动组件20的结构与本实施方式提供的转动组件20的结构相同，并相对于转轴组件10对称设置即可。转动组件20包括转动板21，其中相对两侧的转动板21便是四板转轴套件1中的两个板。转动板21首先可用于承载柔性屏5，为柔性屏5提供刚性支撑，其次转动板21还用于固定连接第一转动件22与第二转动件23，使第一转动件 22与第二转动件23可承载于转动板21上。并且至少部分第一转动件22可设于第一收容空间13内，还可使第一转动件22相对第一支架12进行旋转。这样通过第一转动件22与第一支架12的配合，便可使转动组件20相对转轴组件10进行旋转。
本申请还包括设于转轴组件10相对两侧的壳体组件30，图2仅示意图了一侧的壳体组件30的结构，另一侧的壳体组件30的结构与本实施方式提供的壳体组件30的结构相同，并相对于转轴组件10对称设置即可。壳体组件30包括固定板31，其中相对两侧的固定板31便是四板转轴套件1中的另外两个板。固定板31首先可用于承载柔性屏5，为柔性屏5提供刚性支撑，其次固定板31还用于后续连接壳体4，当固定板31转动时，可带动壳体4一同进行转动。再次，固定板31还用于固定连接第二支架32，使第二支架32可承载于固定板31上。本申请可使至少部分第二转动件23设于第二收容空间33内，还可使第二转动件23相对第二支架32进行旋转。这样通过第二转动件23与第二支架32的配合，便可使壳体组件30相对转动组件20进行旋转，还可使连接在壳体组件30上的壳体4进行旋转。
综上，本申请提供的转轴套件1，通过设于转轴组件10相对两侧转动板21与固定板31组成四板转轴套件1结构，并利用第一转动件22与第一支架12的配合使转动组件20可相对转轴组件10进行旋转，再利用第二转动件23与第二支架32的配合使壳体组件30可相对转动组件20进行旋转，最终使转轴套件1整体可进行多角度旋转。本申请提供的转轴套件1结构简单，只需少量部件便可实现转轴套件1的旋转，从而减少各个部件之间的空隙累积，降低由此带来的尺寸链的大小，减小跌落窜动量，提高转轴套件1的品质。
可选地，所述第二转动件23的转动方向与所述第一转动件22的转动方向保持一致，从而提高转轴套件1的转动角度，使转轴套件1可以在更大角度的范围内进行转动。
可选地，请再次参考图1，可通过在保护壳11，转动板21、固定板31上开设安装孔再通过例如螺钉之类的固定件来固定安装第一支架12、第一转动件22、第二转动件23、以及第二支架32。例如可在保护壳11上开设第一安装孔41从而将第一支架12固定在保护壳11上。可在转动板21的一端开设第二安装孔42从而将第一转动件22固定在转动板21上。还可在转动板21的另一端开设第三安装孔43从而将第二转动件23也固定在转动板21上。还可在固定板31上开设第四安装孔44从而将第二支架32固定在固定板31上。
请一并参考图3，图3为本申请一实施方式中第一支架与第一转动件的结构示意图。本实施方式中，所述第一支架12上设有第一转动部14，所述第一转动件22上设有第二转动部24，所述第一转动部14与所述第二转动部24相配合以使所述第一转动件22可相对所述第一支架12进行旋转。
上述内容提及，第一转动件22可相对第一支架12进行旋转，因此本申请提供了两种实施方式。在一种实施方式中，可在第一支架12上设置第一转动部14，第一转动件22上设置第二转动部24，通过所述第一转动部14与所述第二转动部24相配合以使所述第一转动件22可相对所述第一支架12进行旋转。可选地，第一转动部14可以为滑槽或者导轨，第二转动部24可以为导轨或者滑槽。具体地，当第一转动部14为导轨时，第二转动部24可以为滑槽。当第一转动部14为滑槽时，第二转动部24可以为导轨。本实施方式以第一转动部14为导轨，第二转动部24可以为滑槽进行示意。
请一并参考图4，图4为本申请另一实施方式中第一支架与第一转动件的结构示意图。本实施方式中，所述转轴套件1还包括设于所述第一收容空间13内且连接所述第一支架12的旋转件15，所述第一转动件22套设所述旋转件15以使所述第一转动件22可相对所述第一支架12进行旋转。
在本申请一种实施方式中可通过第一转动部14与第二转动部24的配合来使第一转动件22可相对第一支架12进行旋转。在本申请另一种实施方式中可在第一支架12上增设旋 转件15，并在第一转动件22上开设通孔25。随后只需要将第一转动件22通过通孔25套设旋转件15，这样第一转动件22便可绕着旋转件15进行旋转，从而使第一转动件22可相对所述第一支架12进行旋转。另外，旋转件15还可将第一转动件22装设在第一支架12上。
请一并参考图5-图6，图5为本申请一实施方式中第二支架与第二转动件的结构示意图。图6为本申请另一实施方式中第二支架与第二转动件的结构示意图。上述内容介绍了第一转动件22可相对第一支架12进行旋转的两种实施方式。而对于第二转动件23与第二支架32来说，也可具有相同的结构，从而使第二转动件23可相对第二支架32进行旋转。在本申请一种实施方式中，所述第二支架32上设有第一转动部14，所述第二转动件23上设有第二转动部24，所述第一转动部14与所述第二转动部24相配合以使所述第二转动件23可相对所述第二支架32进行旋转。而在本申请另一种实施方式中，所述转轴套件1还包括设于所述第二收容空间33内且连接所述第二支架32的旋转件15，所述第二转动件23套设所述旋转件15以使所述第二转动件23可相对所述第二支架32进行旋转。
请一并参考图7，图7为本申请另一实施方式中转轴套件的截面示意图。本实施方式中，设于所述转轴组件10相对两侧的所述第一转动件22分别为第一转动件(A)221与第一转动件(B)222，所述转轴套件1还包括第一同步机构2，所述第一同步机构2连接所述第一转动件(A)221与所述第一转动件(B)222，所述第一同步机构2用于使所述第一转动件(A)221与所述第一转动件(B)222同步转动。
转轴套件1中两侧的第一转动件22可以单独进行运动，例如图7中的第一转动件(A)221在运动时，从而带动右侧的转动组件20与壳体组件30一同进行转动。此时另一侧即左侧的第一转动件(B)222此时可处于静止状态，从而使左侧的转动组件20与壳体组件30也可处于静止状态。也可以理解为转轴套件1右侧的部分可进行运动，而左侧的部分则仍处于水平状态。
而在另一种实施方式中，本申请可通过增设第一同步机构2，并使第一同步机构2连接所述第一转动件(A)221与所述第一转动件(B)222，这样当第一转动件(A)221在运动时，可通过第一同步机构2使第一转动件(B)222也一同进行同步运动，进而使相对两侧的转动组件20与壳体组件30也一同进行转动，提高了转轴套件1转轴套件1的对称效果。
请一并参考图8-图12，图8为本申请一实施方式中第一同步机构的结构示意图。图9为图8的爆炸图。图10为图8中第一子支架、第一内齿轮、以及第一直齿轮的结构示意图。图11为图8中第二子支架、第二内齿轮、以及第二直齿轮的结构示意图。图12为图8中第一内齿轮、第二内齿轮、第一直齿轮与第二直齿轮的配合情况示意图。本实施方式中，所述第一同步机构2包括所述第一支架12包括相连接的第一子支架50与第二子支架60，所述第一子支架50内设有第一子收容空间51，所述第二子支架60内设有第二子收容空间61。第一内齿轮70与第二内齿轮72，所述第一内齿轮70设于所述第一转动件(A)221内、所述第一内齿轮70设于所述第一子收容空间51内且可相对所述第一子支架50进行旋转；所述第二内齿轮72设于所述第一转动件(B)222内、所述第二内齿轮72设于所述第二子收容空间61内且可相对所述第二子支架60进行旋转；所述第一内齿轮70内设有第一容置空间71，所述第二内齿轮72内设有第二容置空间73。第一直齿轮80与第二直齿轮83，所述第一直齿轮80包括设于所述第一容置空间71内的第一子直齿轮81与设于所述第一容置空间71外的第二子直齿轮82，所述第一子直齿轮81转动连接所述第一内齿轮70；所述第二直齿轮83包括设于所述第二容置空间73内的第三子直齿轮84与设于所述第二容置空间73外的第四子直齿轮85，所述第三子直齿轮84转动连接所述第二内齿轮72，所述 第四子直齿轮85转动连接所述第二子直齿轮82；当所述第一转动件(A)221转动时，所述第一内齿轮70、所述第二内齿轮72、所述第一直齿轮80、以及所述第二直齿轮83相互配合以使所述第一转动件(A)221与所述第一转动件(B)222同步转动。
本申请提供的第一子支架50用于装设第一内齿轮70与第一直齿轮80，而第二子支架60用于装设第二内齿轮72与第二直齿轮83。并且本申请可将第一子支架50与第二子支架60连接起来，从而降低形成齿轮副的难度，并且可以减少第一同步机构2的尺寸大小。
本申请还提供了第一内齿轮70与第二内齿轮72。其中，内齿轮指的是齿在内圆上的齿轮。本申请可将第一内齿轮70集成在第一转动件(A)221内，再使所述第一内齿轮70设于所述第一子收容空间51内且可相对所述第一子支架50进行旋转。可选地，部分所述第一转动件(A)221设于所述第一子收容空间51内。还可将第二内齿轮72集成在第二转动件23(B)内，再使所述第二内齿轮72设于所述第二子收容空间61内且可相对所述第二子支架60进行旋转。可选地，部分所述第一转动件(B)222设于所述第二子收容空间61内。其中，第一子收容空间51便用于装设第一内齿轮70，而第一内齿轮70还可相对第一子支架50进行旋转。可选地，第一内齿轮70的旋转方向与第一内齿轮70的齿的排列方向保持一致。而第二子收容空间61便用于装设第二内齿轮72，第二内齿轮72还可相对第二子支架60进行旋转。可选地，第二内齿轮72的旋转方向与第二内齿轮72的齿的排列方向保持一致。
本申请还提供了第一直齿轮80与第二直齿轮83。其中，第一直齿轮80包括设于所述第一容置空间71内的第一子直齿轮81与设于所述第一容置空间71外的第二子直齿轮82，也可以理解为，由于第一内齿轮70的齿位于内圆，部分第一直齿轮80需设于第一容置空间71内并与第一内齿轮70转动连接，从而形成齿轮副。而其余的第一直齿轮80设于第一容置空间71外。第二直齿轮83也可做同样的理解，所述第二直齿轮83包括设于所述第二容置空间73内的第三子直齿轮84与设于所述第二容置空间73外的第四子直齿轮85，也可以理解为，由于第二内齿轮72的齿位于内圆，部分第二直齿轮83需设于第二容置空间73内并与第二内齿轮72转动连接，从而形成齿轮副。而其余的第二直齿轮83设于第二容置空间73外并与其余的设于第一容置空间71外的第一直齿轮80转动连接，即第四子直齿轮85转动连接第二子直齿轮82，形成齿轮副。
综上，本申请提供的第一同步机构2，通过利用两个内齿轮与两个直齿轮四个齿轮的相互配合，形成三个齿轮副，也可以理解为，第一内齿轮70与第一子直齿轮81构成第一个齿轮副，第二子直齿轮82与第四子直齿轮85构成第二个齿轮副，第三子直齿轮84与第二内齿轮72构成第三个齿轮副。当第一转动件(A)221中的第一内齿轮70转动时，第一内齿轮70与第一子直齿轮81同步转动，第一子直齿轮81与第二子直齿轮82同步转动，第二子直齿轮82与第四子直齿轮85同步转动，第四子直齿轮85与第三子直齿轮84同步转动，第三子直齿轮84与第二内齿轮72同步转动，由由于第二内齿轮72设于第一转动件(B)222内，最终便可实现第一转动件(A)221与第二转动件23(B)实现同步转动。本申请提供的第一同步机构2，结构简单，使用三个齿轮副便可实现第一转动件(A)221与第二转动件23(B)的同步转动，齿轮副数量的减少可减少累积的空程量，提高第一同步机构21的同步效果。
请一并参考图13，图13为本申请一实施方式中第一直齿轮与第二直齿轮的结构示意图。本实施方式中，所述第二子直齿轮82的直径大于所述第一子直齿轮81；所述第四子直齿轮85的直径大于所述第三子直齿轮84。
当第一同步机构2在运动时，即第一内齿轮70与第二内齿轮72在同步转动时，第一直齿轮80与第二直齿轮83之间的距离会产生微小的偏差，例如当第一内齿轮70与第二内 齿轮72转动90°时，若第二子直齿轮82与第一子直齿轮81的直径相等，第四子直齿轮85与第三子直齿轮84的直径相等，此时第二子直齿轮82与第四子直齿轮85之间可能会产生一定的间隙，从而使得啮合不完全。因此，本申请使所述第二子直齿轮82的直径大于所述第一子直齿轮81；所述第四子直齿轮85的直径大于所述第三子直齿轮84，从而使无论第一内齿轮70与第二内齿轮72运动多少角度，第二子直齿轮82与第四子直齿轮85均可完全啮合，从而提高第一同步机构2的同步效果。
请一并参考图14，图14为本申请一实施方式中第一子支架与第一直齿轮的结构示意图。本实施方式中，所述第一子支架50上开设有第一通孔52，所述第一直齿轮80贯穿所述第一通孔52。
本申请可在第一子支架50上开设有第一通孔52，并使第一直齿轮80贯穿第一子支架50第一通孔52，从而将第一直齿轮80装设于第一子支架50上，并使第一直齿轮80可相对第一子支架50进行旋转。并且第一通孔52的开设还可使第一直齿轮80装设后第一子直齿轮81可与第一内齿轮70转动连接。这样当第一内齿轮70运动旋转时，便可使第一子直齿轮81同步旋转，进而使第二子直齿轮82同步旋转。可选地，第一子支架的相对两侧均可开设第一通孔52，从而进一步提高对第一直齿轮80的安装效果。
请一并参考图15，图15为本申请一实施方式中第一子支架与第二子支架的结构示意图。本实施方式中，所述第一子支架50上设有第一定位部53，所述第二子支架60上设有第二定位部62，所述第一定位部53与所述第二定位部62相互配合以使所述第一子支架50连接所述第二子支架60。
上述内容提及第一子支架50可与第二子支架60连接构成本申请的第一支架12。因此在本实施方式中，可在第一子支架50上设置第一定位部53，在第二子支架60上设置第二定位部62，第一定位部53与第二定位部62相对设置，并通过所述第一定位部53与所述第二定位部62相互配合以使所述第一子支架50连接所述第二子支架60。可选地，第一定位部53可以为凸块或者凹槽98，第二定位部62可以为凹槽98或者凸块。进一步可选地，第一定位部53包括相对设置的第一子定位部531与第二子定位部532，第二定位部62包括相对设置的第三子定位部621与第四子定位部622。如图15所示，第一子定位部531可以为凸块，第二子定位部532可以为凹槽98，而第三子定位部621可以为凹槽98，第四子定位部622可以为凸块，从而进一步提高第一子支架50与第二子支架60的连接效果。当然了，本申请仅以图15所示的实施方式进行示意，其他实施方式也可同样达到本申请的有益效果。
请一并参考图16-图19，图16为本申请又一实施方式中转轴套件的截面示意图。图17为图16中的部分立体结构示意图。图18为本申请一实施方式中在第一支架上补偿组件的转动中心与第一转动件的转动中心的示意图。图19为本申请又一实施方式中当转轴套件弯折后的截面示意图。本实施方式中，所述转轴套件1还包括设于所述转轴组件10相对两侧的补偿组件90，所述补偿组件90的一端转动连接所述第一支架12，且所述补偿组件90的转动中心(如图18中的字母D所示)与所述第一转动件22的转动中心(如图18中的字母C所示)之间具有间距。所述补偿组件90的另一端连接所述壳体组件30，且所述壳体组件30可相对所述补偿组件90进行滑动以使所述固定板31与所述补偿组件90之间的距离可调。
当转轴套件1应用电子设备3中时可首先柔性屏5的弯折，从而形成柔性电子设备3。当柔性屏5的弯折方式为内折时，其普遍有两种弯折方式：U型屏和水滴形屏。但U型屏会使得电子设备3整机厚度较厚。而水滴形屏则可使得电子设备3整机较薄。因此，本申请可通过在上述转轴套件1结构的基础上增设补偿组件90，利用补偿组件90与其他组件 的配合来使柔性屏5形成水滴屏。
具体地，本申请可使补偿组件90的一端转动连接第一支架12，使补偿组件90可相对第一支架12进行旋转。可选地，所述补偿组件90的转动方向与所述第一转动件22的转动方向保持一致，并且为了形成水滴屏，本申请还可使所述补偿组件90的转动中心(如图18中的字母D所示)与所述第一转动件22的转动中心(如图18中的字母C所示)之间具有间距。也可以理解为，如图18所示，补偿组件90的转动中心与第一转动件22的转动中心并不重合，这样当转轴套件1在转动时，便会产生曲柄滑块运动，从而使第一转动件22与补偿组件90产生不同的转动，形成位置距，最终形成水滴屏。
另外，本申请还可使补偿组件90的另一端连接所述壳体组件30，且所述壳体组件30可相对所述补偿组件90进行滑动以使所述固定板31与所述补偿组件90之间的距离可调。当转轴套件1应用与电子设备3且柔性屏5进行内折时，为了实现曲柄滑块运动。本申请可通过控制补偿壳体组件30，即使固定板31与补偿组件之间的距离可调整，从而保证转轴套件1的正常弯折，进而形成水滴屏。从图16与图19中可以看出，图16为转轴套件1处于展平状态时的截面示意图。此时补偿组件90与壳体组件30的总长度为第一长度。而图19为转轴套件1运动90°后的截面示意图。此时由于产生曲柄滑块运动，因此所述壳体组件30相对所述补偿组件90进行滑动，此时补偿组件90与壳体组件30的总长度为第二长度，此时第二长度大于第一长度。至于补偿组件90如何相对第一支架12进行旋转，以及补偿组件90与壳体组件30之间的距离如何实现调整，在下文将做详细介绍。
请一并参考图17与图20，图20为本申请一实施方式中补偿组件、第一支架、以及第二支架的结构示意图。本实施方式中，所述补偿组件90包括补偿板91，所述补偿板91包括相对设置的第一端901与第二端902，所述第一端901设有第三转动部94，所述第一支架12上设有第四转动部95，所述第三转动部94与所述第四转动部95相配合以使所述补偿板91可相对所述第一支架12进行转动。
本申请提供的补偿组件90包括补偿板91，其中补偿板91首先用于装设第三转动部94，并且补偿组件90还可配合电子设备3中的壳体4来构成电子设备3的外壳。另外，补偿组件90由于不需承载柔性屏5，因此补偿板91并不算做四板转轴套件1中的板。本申请可通过在补偿板91的第一端901设置第三转动部94，在第一支架12上设置第四转动部95，通过所述第三转动部94与所述第四转动部95相配合以使所述补偿板91可相对所述第一支架12进行转动。可选地，第三转动部94可以为凸块或过孔，第四转动部95可以为过孔或凸块。进一步可选地，当第三转动部94为凸块时，第四转动部95可以为过孔。当第三转动部94为过孔时，第四转动部95可以为凸块。本实施方式以第三转动部94为凸块，第四转动部95为过孔进行示意。
请再次参考图17与图20。本实施方式中，所述第二端902设有第一滑动部92，所述第二支架32上设有第二滑动部93，所述第一滑动部92与所述第二滑动部93相互配合以使所述补偿板91与所述固定板31之间的距离可调。
本申请为了使补偿组件90与固定板31之间的距离可调，可在补偿板91的第二端902上设置第一滑动部92，在第二支架32上设置第二滑动部93，通过第一滑动部92与所述第二滑动部93相互配合以使所述补偿板91与所述固定板31之间的距离可调。可选地，第一滑动部92可以为滑槽或滑轨，第二滑动部93可以为滑轨或滑槽。进一步可选地，当第一滑动部92为滑槽时，第二滑动部93可以为滑轨。当第一滑动部92为滑轨时，第二滑动部93可以为滑槽。本实施方式以第一滑动部92为滑槽，第二滑动部93可以为滑轨进行示意。本实施方式通过增设滑槽，并将滑槽固定在补偿板91上，并且在第二支架32的相对两侧凸设出滑轨，从而使第二支架32可沿滑槽进行滑动从而改变补偿板91与固定板31之间的 距离。
请一并参考图21，图21为本申请又一实施方式中转轴套件的截面示意图。本实施方式中，所述转轴套件1还包括第二同步机构，所述第二同步机构包括设于所述第三转动部94或所述第四转动部95上的第一齿轮96，以及设于所述第一支架12上的齿轮组97，所述齿轮组97转动连接所述第一齿轮96。当设于所述转轴组件10一侧的所述补偿组件90转动时，通过所述第一齿轮96与所述齿轮组97的相互配合，以使所述转轴组件10相对两侧的所述补偿组件90同步转动。
从上述内容可知，可在转轴套件1中增设第一同步机构2，从而让相对两侧的第一转动件22同步转动，从而带动相对两侧的转动组件20与壳体组件30同步转动。本申请还可通过增设第二同步机构，从而使相对两侧的补偿组件90同步转动，进而更好地形成水滴屏。具体地，可通过在第三转动部94或第四转动部95上设置第一齿轮96，由于补偿组件90设于相对两侧，即补偿组件90的数量为两个，因此第一齿轮96的数量也为两个，并且相对设置。随后在第一支架12上设置齿轮组97，即在两个第一齿轮96之间设置齿轮组97，使齿轮组97同时转动连接相对两侧的第一齿轮96，从而使相对两侧的补偿组件90可同步转动。具体地，当一侧的补偿组件90开始转动时可通过第三转动部94或第四转动部95带动改侧的第一齿轮96进行转动，此时第一齿轮96带动齿轮组97同步转动，而该齿轮组97带动另一侧的第一齿轮96同步转动，另一侧的第一齿轮96带动另一侧的补偿组件90进行转动，最终使相对两侧的补偿组件90同步转动。
可选地，齿轮组97包括两个齿轮。可选地，第一齿轮96与齿轮组97可设于第一支架12上开设的凹槽98中(如图17或图20所示)。
除了上述介绍的转轴套件1，本申请实施方式还提供了一种电子设备3。本申请提供的电子设备3及转轴套件1都可以实现本申请的优点。作为一种选择，可以使用上文提供的转轴套件1来形成下文的电子设备3。
请一并参考图22-图26，图22为本申请一实施方式中电子设备的结构示意图。图23为图22沿A-A方向的截面示意图。图24为图22中去除柔性屏后的部分分解结构示意图。图25为本申请一实施方式中电子设备运动后的结构示意图。图26为本申请一实施方式中电子设备运动后的截面示意图。本实施方式还提供了一种电子设备3，所述电子设备3包括壳体4、柔性屏5、以及如本申请上述实施方式提供的转轴套件1，所述柔性屏5装设于所述壳体4上，所述壳体4包括相对设置的第一子壳体401与第二子壳体402，所述第一子壳体401连接设于所述转轴套件1一侧的壳体组件30，所述第二子壳体402连接设于所述转轴套件1另一侧的所述壳体组件30。
本申请提供的电子设备3包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、个人计算机(Personal Computer，PC)、个人数字助理(Personal Digital Assistant，PDA)、便携式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等移动终端，以及诸如数字TV、台式计算机等固定终端。
本申请提供的电子设备3可将柔性屏5装设于壳体4上，可选地，所述柔性屏5也装设于所述转轴套件1上以使所述柔性屏5可进行内折，从而形成水滴屏。通过上述内容可知，当转轴套件1包括转轴组件10、转动组件20、以及壳体组件30时，可使转轴套件1进行弯折，从而带动连接壳体组件30的壳体4进行弯折，最后带动柔性屏5进行弯折，可形成U型屏。当转轴套件1还包括补偿组件90时，利用曲柄滑块运动的原理，在转轴套件1转动时，使转动组件20和壳体组件30保持角度倾斜，也可以理解为，当壳体4转动90°时，转动组件20和壳体组件30可转动大于90°，从而使柔性屏5弯折时呈现水滴的效果。随后再使壳体组件30相对于转动组件20沿转动方向的反方向进行转动，使柔性屏5 的相对两端距离减小，进一步形成水滴屏(如图26所示)。
本申请提供的电子设备3，通过利用本申请上述实施方式提供的转轴套件1，可减小转轴套件1中各个部件之间的空隙累积，降低由此带来的尺寸链的大小，减小跌落窜动量，提高转轴套件1与电子设备3的品质。
请再次参考图3、图4、以及图26。本实施方式中，所述转轴套件1包括转轴组件10，所述转轴组件10包括第一支架12，所述第一支架12靠近所述柔性屏5的一侧开设有避让槽6，所述避让槽6用于当所述电子设备3弯折时收容部分所述柔性屏5。
当电子设备3在弯折的过程中，柔性屏5的弯折处会朝向第一支架12的方向产生一定的位移。因此本申请可在第一支架12上开设避让槽6，也可以理解为，在第一支架12靠近柔性屏5的一侧表面开设避让槽6。这样当柔性屏5在弯折时，避让槽6可收容部分朝向第一支架12方向发生位移的柔性屏5，从而防止柔性屏5在弯折时碰撞到第一支架12。
以上对本申请实施方式所提供的内容进行了详细介绍，本文对本申请的原理及实施方式进行了阐述与说明，以上说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
