Description

折叠屏设备
本申请要求于2022年07月19日提交中国专利局、申请号为202210848019.6、申请名称为“折叠屏设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及终端技术领域，特别涉及一种折叠屏设备。
背景技术
随着电子设备的爆发式增长，电子设备的功能越来越多。电子设备的显示屏用于向用户呈现图像信息。在一些使用场景下，用户期望电子设备的显示屏可以具有更大的显示面积。目前电子设备为单屏显示，更大的显示面积意味着电子设备的尺寸更大，从而使得电子设备失去了便携性。
为了平衡电子设备的尺寸和显示面积，电子设备可以采用折叠式结构。例如，两个框体可以绕转轴组件中的转轴相对旋转。在两个框体上覆盖柔性显示屏。两个框体绕转轴旋转至同一平面时，柔性显示屏呈展开状态，并具有较大的显示面积。两个框体绕转轴旋转至相互折叠时，柔性显示屏呈折叠状态，并且电子设备具有较小的体积。两个框体内设置有电子器件。不同框体内的电子器件通过跨越转轴的柔性的电连接线实现电连接。
为了适配电子设备可折叠和展开的形态变化，柔性的电连接线需要具有冗余长度。两个框体处于折叠状态时，柔性的电连接线可以处于绷紧状态。两个框体处于展开状态时，柔性的电连接线处于松弛、自由状态，产生长度冗余。然而，电子设备每次折叠、展开时，柔性的电连接线呈现不同的弯曲状态，容易出现折弯角度过小而导致弯折断线的问题。
发明内容

相关技术中，折叠屏设备包括框体、转轴组件和电连接线。转轴组件的两侧分别设置框体。框体可以相对转轴组件旋转，使得两个框体可以在折叠状态和展开状态之间变化。两个框体中分别设置有电子器件。不同框体内的电子器件可以通过柔性的电连接线实现电连接。电连接线穿过转轴组件设置。两个框体在折叠状态和展开状态切换时，电连接线的形态会发生变化。两个框体在展开状态时，电连接线产生长度冗余并且呈自由弯曲状态。然而，对于框体每次折叠、展开，电连接线会呈现不同的弯曲状态，使得电连接线容易出现弯折半径过小而导致发生磨损、断线的问题，从而导致电连接线失效，电子设备发生故障。
本申请实施例提供的折叠屏设备，可以对电连接线的形态变化进行引导定型，并且可以有效吸收电连接线的冗余长度，有利于框体每次折叠、展开时，电连接线弯曲状态可以保持一致，降低电连接线出现弯折半径过小而导致电连接线发生磨损或断线的可能性。下面对本申请实施例提供的可实现方式进行阐述。
图1示意性地显示了一实施例的折叠屏设备10展开状态的结构。图2示意性地显示了折叠屏设备10半折叠状态的结构。图3示意性地显示了折叠屏设备10折叠状态的结构。参见图1至图3所示，折叠屏设备10包括壳体20和柔性显示屏30。壳体20包括转轴组件21和框体22。框体22可转动连接于转轴组件21。转轴组件21相对两侧分别设置有框体22。柔性显示屏30连接于框体22。
框体22可以相对转轴组件21转动、翻折。本申请中，以折叠屏设备10包括两个框体22为示例进行说明。两个框体22相互层叠时，折叠屏设备10处于折叠状态。两个框体22从层叠状态相互远离并且展开至同一平面时，折叠屏设备10处于展开状态。框体22从折叠状态到展开状态的过程为展开过程，而从展开状态到折叠状态为折叠过 程。
图4示意性地显示了本申请的折叠屏设备10的局部分解结构。参见图4所示，柔性显示屏30包括用于显示图像信息的显示部。折叠屏设备10处于展开状态时，柔性显示屏30的显示部展开以便于向用户呈现图像信息。显示部包括第一显示区域31、第二显示区域32和第三显示区域33。第一显示区域31和第二显示区域32分别对应两个框体22设置。第三显示区域33对应转轴组件21设置。柔性显示屏30自身具有可折弯性能，受外力作用后可以实现折叠。
两个框体22处于折叠状态时，显示部处于折弯状态。显示部的第一显示区域31和第二显示区域32相互层叠，而第三显示区域33可以折弯成弧形状态。
两个框体22处于展开状态时，显示部处于展开状态，而第一显示区域31、第二显示区域32和第三显示区域33呈现平整状态。柔性显示屏30的显示部处于展开状态时，整体具有良好的平整性。
折叠屏设备10通过折叠或展开的方式，可以改变自身整体尺寸，同时展开状态下也可以具有较大的显示面积。
参见图4所示，折叠屏设备10的两个框体22中可以分别设置有电子器件80，例如，电子器件80可以包括但不限于处理器、存储器或摄像模组。折叠屏设备10还包括电连接线40。电连接线40穿过转轴组件21设置。电连接线40的两个端部41设置于转轴组件21两侧的框体22内。示例性地，电连接线40相对的两个端部41分别与转轴组件21两侧的框体22连接。需要说明的是，电连接线40的端部41与框体22连接可以指的是电连接线40的端部41直接与框体22连接固定，或者，电连接线40的端部41连接固定于框体22内的其他结构件上，以通过该结构件间接连接固定于框体22内。两个框体22中各自的电子器件80可以通过电连接线40实现电连接以传送电信号。在一些示例中，框体22内设置有印制电路板70(Printed Circuit Board，PCB)。电子器件80设置于印制电路板70。电连接线40可以与印制电路板70电连接。电连接线40的端部41可以通过印制电路板70间接连接固定于框体22内。
在一些可实现的方式中，电连接线40可以包括柔性电路板(Flexible Printed Circuit，FPC)。柔性电路板可以包括多条走线，以用于传输多个不同的电信号。在一些示例中，电连接线40可以包括两个以上的柔性电路板。两个以上的柔性电路板相互层叠设置。两个以上的柔性电路板可以在各自的端部相连，而各自的其他区域可以无连接关系。
在一些可实现的方式中，电连接线40可以包括至少一条单根独立设置的线缆。线缆可以用于电连接分别设置于两个框体22内的两个电子器件80。
图5示意性地显示了相关技术的一种折叠屏设备的局部剖视结构。参见图5所示，电连接线40自身为柔性结构。框体22发生位置变化时，电连接线40可以产生相应的形变。两个框体22处于折叠状态时，电连接线40可以处于绷紧状态。图6示意性地显示了相关技术的一种折叠屏设备的局部剖视结构。参见图6所示，在框体22处于展开状态时，电连接线40会变得松弛并且长度会出现冗余，从而自身会发生自由弯曲形变，使得电连接线40容易出现弯折半径较小的弯折区域。
图7示意性地显示了本申请的折叠屏设备10的局部剖视结构。参见图7所示，壳 体20还包括容纳部23。容纳部23设置于转轴组件21和框体22上。容纳部23贯穿转轴组件21并且延伸至框体22内，从而容纳部23可以形成走线通道。电连接线40的至少部分位于容纳部23内。电连接线40穿过转轴组件21设置。折叠屏设备10还包括定型部件50。定型部件50设置于容纳部23内并且与壳体20相连。定型部件50的至少部分位于壳体20和电连接线40之间。定型部件50用于对电连接线40位于容纳部23内的部分引导定型。定型部件50可以设置于壳体20面向容纳部23的表面。在两个框体22从折叠状态切换至展开状态时，定型部件50可以对电连接线40弯曲过程中的形态变化进行引导定型，使得电连接线40可以向预期的弯曲状态发生形变。另外，定型部件50可以抵接于电连接线40，以使电连接线40上对应区域形成弯折区，从而增加电连接线40上弯折区的数量，继而可以吸收电连接线40的冗余长度。
本申请实施例的折叠屏设备10，电连接线40的两个端部41分别设置于两个框体22内。电连接线40穿过转轴组件21设置。至少部分的电连接线40位于壳体20的容纳部23内。折叠屏设备10还包括设置于容纳部23内的定型部件50。在两个框体22从折叠状态切换至展开状态，电连接线40会产生长度冗余。定型部件50可以对电连接线40位于容纳部23内的部分进行引导定型，使得电连接线40可以向预期的弯曲状态发生形变。定型部件50可以与电连接线40接触，以使电连接线40的相应区域形成弯折区，增加弯折区的数量，以此可以吸收电连接线40的冗余长度。因此，两个框体22每次折叠、展开时，电连接线40在定型部件50的引导定型作用下，自身弯曲状态可以保持一致，并且定型部件50可以吸收电连接线40的冗余长度，从而有利于增大电连接线40上形成的弯折区的弯折半径，降低电连接线40因长度冗余而任意弯曲形变并出现弯折半径过小，导致电连接线40发生磨损或断线的可能性，有利于提高电连接线40和折叠屏设备10的可靠性。
折叠屏设备10在一些使用场景中，例如，折叠屏设备10在携带状态下，折叠屏设备10通常处于折叠状态，使得折叠屏设备10折叠状态的整体厚度尺寸对使用过程的便利性和体验具有较大影响。本申请的折叠屏设备10设置的定型部件50可以在有限的空间内保证电连接线40形成半径较大的弯折区，从而可以有利于在电连接线40弯曲形态满足要求的情况下减小折叠屏设备10的厚度，以提升折叠屏设备10的便利性和体验。
在一些可实现的方式中，由于电连接线40会与定型部件50面向电连接线40的表面发生接触，因此在两者接触后，定型部件50和电连接线40彼此之间存在压应力。定型部件50面向电连接线40的表面可以为曲面。因此，在定型部件50与电连接线40接触时，定型部件50和电连接线40之间的接触区域平缓过渡，可以有利于分散两者之间存在的压应力，降低定型部件50因对电连接线40局部施加较大压力而导致电连接线40出现应力集中发生破裂或断线的可能性。在电连接线40接触到定型部件50时，定型部件50面向电连接线40的表面可以更好地引导电连接线40发生弯折，形成弯折半径较大的弯折区。
在一些示例中，定型部件50面向电连接线40的表面为弧形面。示例性地，定型部件50面向电连接线40的表面包括多个圆弧面。多个圆弧面之间圆滑过渡。
在一些可实现的方式中，转轴组件21面向容纳部23的表面设置有定型部件50。 定型部件50朝向容纳部23凸出，以使电连接线40位于转轴组件21处的部分可以在凸出的定型部件50引导作用下形成弯折区，以吸收电连接线40产生的冗余长度。电连接线40位于转轴组件21内的部分处于自由状态，即电连接线40与转轴组件21之间处于不连接状态，使得电连接线40不受转轴组件21的牵拉约束，从而电连接线40位于转轴组件21内的部分容易随着框体22的折叠或展开而发生形态变化。
在一些示例中，参见图7所示，转轴组件21包括轴盖211。轴盖211可以位于两个框体22之间。轴盖211可以遮挡转轴组件21内部的其他结构件，使得电子设备外观整洁、美观。两个框体22相对转轴组件21转动时，轴盖211的位置可以保持相对固定。在一些示例中，两个框体22处于展开状态时，两个框体22可以将轴盖211遮挡住以使轴盖211处于不可见状态。两个框体22处于折叠状态时，至少部分的轴盖211可以外露于两个框体22而处于可见状态。
电连接线40跨越轴盖211设置。电连接线40的两个端部41分别位于轴盖211的两侧。定型部件50可以设置于轴盖211面向容纳部23的内壁。定型部件50设置于轴盖211和电连接线40之间。定型部件50用于对电连接线40位于轴盖211内的部分进行引导定型，使得电连接线40在定型部件50的作用下形成弯折区。电连接线40可以在轴盖211处有限的空间内形成半径较大的弯折区，以吸收电连接线40产生的冗余长度。
在一些示例中，图8示意性地显示了本申请的折叠屏设备10的局部剖视结构。参见图8所示，轴盖211可以包括凹陷部211a。轴盖211的凹陷部211a形成为容纳部23的一部分空间。由于轴盖211包括凹陷部211a，因此容纳部23在轴盖211处的空间较大，使得框体22在展开状态时，电连接线40的一部分可以以弯曲形态收纳于轴盖211的凹陷部211a内。定型部件50可以对电连接线40引导定型，以使得电连接线40可以以预期的弯曲形态收纳于轴盖211的凹陷部211a内。
在一些示例中，定型部件50面向电连接线40的表面与轴盖211的内壁之间圆弧过渡，从而在定型部件50和轴盖211之间过渡平缓、光滑，降低因定型部件50和轴盖211之间存在尖锐凸起结构而导致电连接线40易于受到结构破坏或划伤的可能性。
在一些示例中，电连接线40的中间部分位于轴盖211内。在框体22从折叠状态向展开状态切换时，电连接线40发生长度冗余，并且在自身内应力的作用下，电连接线40的中间部分会朝向轴盖211的中间区域211b移动。因此，轴盖211的中间区域211b设置有定型部件50，使得电连接线40的中间部分可以较早地与定型部件50发生接触，并且电连接线40的中间部分在定型部件50的作用下形成半径较大的弯折区，以吸收电连接线40的冗余长度，从而电连接线40的中间部分以及位于中间部分两侧的部分之间也可以形成半径较大的弯折区。
在一些示例中，图9示意性地显示了本申请的折叠屏设备10的局部剖视结构。参见图9所示，轴盖211上位于中间区域211b两侧的边缘区域211c均设置有定型部件50。边缘区域211c设置的定型部件50可以靠近凹陷部211a的开口设置。相对于中间区域211b设置的定型部件50，可以更加靠近电连接线40的端部41。中间区域211b以及边缘区域211c设置的定型部件50均可以对电连接线40位于轴盖211处的部分引导定型，进一步使得电连接线40可以向预期的弯曲形态发生形变。中间区域211b以 及边缘区域211c设置的定型部件50均可以使电连接线40上对应区域形成弯折区，有利于进一步增加弯折区的数量，以在有限的空间内更多地吸收电连接线40的冗余长度，增大各个弯折区的半径，从而有利于进一步减小折叠屏设备10的厚度，不易出现因折叠屏设备10厚度减小而压缩容纳部23空间，导致电连接线40冗余长度过大而出现弯折区半径过小的问题。
在一些示例中，定型部件50和轴盖211之间圆弧过渡，使得中间区域211b设置的定型部件50以及边缘区域211c设置的定型部件50之间形成弧形凹陷。电连接线40的一部分可以位于弧形凹陷内。
在一些示例中，参见图9所示，电连接线40包括两个以上的柔性电路板。两个以上的柔性电路板层叠设置。在框体22展开过程中，如果各个柔性电路板弯曲形态不一致，则各个柔性电路板之间会出现分层现象。分层后的柔性电路板再次发生相互贴合时，容易产生相互拍打而导致折叠屏设备10产生异响的问题，影响用户体验。中间区域211b以及边缘区域211c设置的定型部件50可以有效限制各个柔性电路板的活动空间，并且定型部件50可以在框体22展开过程中对各个柔性电路板的弯曲形态进行引导定型，使得各个柔性电路板的冗余长度以相同的形态被吸收，从而各个柔性电路板的弯曲形态变化趋势保持一致，降低因各个柔性电路板弯曲形态不一致导致各个柔性电路板之间出现分层的可能性，进而有利于消除因柔性电路板相互拍打而产生异响的问题。在一些示例中，定型部件50可以为沿柔性电路板的宽度方向延伸的条形结构，从而可以在柔性电路板的宽度方向上对柔性电路板整体进行充分地引导定型。
在一些示例中，中间区域211b可以设置一个定型部件50，而两侧的边缘区域211c可以分别设置一个定型部件50，即轴盖211上设置有三个定型部件50。但可以理解地，中间区域211b以及边缘区域211c可以设置其他数量的定型部件50，本申请对此不作具体限定。
在一些示例中，中间区域211b设置的定型部件50的凸出高度大于边缘区域211c设置的定型部件50的凸出高度，一方面，可以保证边缘区域211c设置的定型部件50占用较少的空间，以使轴盖211处具有足够的收纳空间收纳电连接线40；另一方面，如果边缘区域211c设置的定型部件50凸出高度过高，存在电连接线40受到边缘区域211c设置的定型部件50的挤压，导致电连接线40未能与中间区域211b设置的定型部件50发生接触或者接触面积偏小，从而导致中间区域211b设置的定型部件50未能有效发挥作用，而本实施例的方案可以有利于降低发生上述问题的可能性。
在一些示例中，两侧边缘区域211c设置的定型部件50各自的形状和尺寸可以相同，从而可以提高电连接线40在与两侧定型部件50对应区域弯曲形态的一致性，提高电连接线40在与两侧定型部件50对应区域形成的弯折区的半径的一致性。
在一些示例中，轴盖211和定型部件50为一体成型结构。轴盖211和定型部件50之间连接强度高，从而在电连接线40对定型部件50施加作用力时，不易出现定型部件50与轴盖211发生分离的情况。另外，轴盖211和定型部件50可以同时加工制造，有利于减少后期组装的工序，提高生产效率。
在一些示例中，参见图9所示，中间区域211b设置的定型部件50凸出轴盖211的底壁的高度可以为H1。轴盖211的底壁至顶端面的高度可以为H2。其中，0.5≤H1 ＜0.5H2。示例性地，H2的取值范围可以为1毫米至4毫米。
在一些示例中，图10示意性地显示了本申请的折叠屏设备10的局部剖视结构。参见图10所示，定型部件50可以为柔性件。定型部件50连接于轴盖211。示例性地，定型部件50可以粘接于轴盖211的内壁，例如，定型部件50可以通过粘接剂或者双面胶带粘接于轴盖211的内壁。柔性的定型部件50具有良好的柔软度，从而电连接线40与定型部件50发生接触时，定型部件50与电连接线40之间不易发生磨损，降低因电连接线40长期受到定型部件50磨损而导致电连接线40发生结构损坏或者断线失效的可能性。示例性地，定型部件50的材料可以是泡棉。
在一些可实现的方式中，参见图10所示，框体22包括屏幕支撑板221和柔性防护件222。柔性显示屏30设置于屏幕支撑板221。屏幕支撑板221用于为柔性显示屏30提供支撑力，防止柔性显示屏30发生塌陷。框体22处于展开状态时，两个屏幕支撑板221可以使得柔性显示屏30保持平整状态。柔性防护件222设置于屏幕支撑板221面向电连接线40的表面。柔性显示屏30和柔性防护件222分别设置于屏幕支撑板221相对的两侧。柔性防护件222面向转轴组件21设置。电连接线40穿设于转轴组件21和柔性防护件222之间。在电连接线40发生弯曲形变时，电连接线40可以与柔性防护件222发生接触，而柔性防护件222可以对电连接线40起到缓冲防护作用，降低电连接线40直接与屏幕支撑板221上存在的尖角结构发生接触而导致电连接线40发生结构损坏的可能性。在一些示例中，柔性防护件222的材料可以是泡棉。
在一些可实现的方式中，图11示意性地显示了本申请的折叠屏的局部剖视结构。参见图11所示，框体22面向容纳部23的表面设置有定型部件50。容纳部23位于框体22内的空间可以收纳电连接线40。定型部件50用于对电连接线40位于框体22处的部分引导定型。框体22上设置的定型部件50更加靠近电连接线40的端部41。在框体22从折叠状态向展开状态切换时，电连接线40上位于框体22内的部分会发生长度冗余，并且在自身内应力的作用下，电连接线40上位于框体22内的部分会发生弯曲形变。因此，框体22上设置的定型部件50可以使得电连接线40的相应区域出现弯折并形成半径较大的弯折区，以吸收电连接线40的冗余长度，并且定型部件50可以引导电连接线40弯曲形变，有利于提高电连接线40反复弯曲时的弯曲形态一致性。
在一些示例中，参见图11所示，框体22上位于电连接线40两侧的区域分别设置有定型部件50。电连接线40从两侧的定型部件50之间穿过。两侧的定型部件50均可以对电连接线40位于框体22处的部分引导定型，进一步保证电连接线40向预期的弯曲形态发生形变。两侧的定型部件50均可以使电连接线40上对应区域形成弯折区，有利于进一步增加弯折区的数量，以在有限的空间内更多地吸收电连接线40的冗余长度，增大各个弯折区的半径，从而有利于减小折叠屏设备10的厚度，不易出现因折叠屏设备10厚度减小而压缩容纳部23空间，导致电连接线40冗余长度过大而出现弯折区半径过小的问题。
在一些示例中，电连接线40的中间部分连接于转轴组件21。示例性地，电连接线40的中间部分粘接于转轴组件21。例如，电连接线40的中间部分可以通过粘接剂或双面胶带粘接于转轴组件21。电连接线40的中间部分受到转轴组件21的约束，使得电连接线40的中间部分不能相对转轴组件21自由移动或弯曲。框体22上设置的定 型部件50可以对电连接线40上伸出转轴组件21的部分进行引导定型。
在一些示例中，参见图11所示，壳体20还包括支撑件60。支撑件60对应转轴组件21的轴盖211设置。电连接线40的中间部分可以从支撑件60和轴盖211之间穿过。在框体22和柔性显示屏30处于折叠状态时，支撑件60用于为柔性显示屏30上弯折的第三显示区域33提供支撑，以使柔性显示屏30上弯折的第三显示区域33可以呈现水滴形，降低柔性显示屏30的第三显示区域33出现弯折半径过小而导致第三显示区域33出现折痕或裂纹的可能性。
在一些示例中，框体22和定型部件50为一体成型结构。框体22和定型部件50之间连接强度高，从而在电连接线40对定型部件50施加作用力时，不易出现定型部件50与框体22发生分离的情况。另外，框体22和定型部件50可以同时加工制造，有利于减少后期组装的工序，提高生产效率。
在一些示例中，参见图12所示，框体22面向容纳部23的相对两个表面之间的间距可以为H0。其中一个表面上设置的定型部件50凸出的高度可以为H3，另一个表面上设置的定型部件50凸出的高度可以为H4。电连接线40可以为柔性电路板。柔性电路板的厚度可以为h。一个表面上设置的定型部件50凸出的高度H3的取值范围可以为：0.5H0＞H3＞2h。另一个表面上设置的定型部件50凸出的高度H4的取值范围可以为：0.5H0＞H4＞2h。
在一些示例中，图13示意性地显示了本申请的折叠屏设备10的局部剖视结构。参见图13所示，定型部件50可以为柔性件。定型部件50连接于框体22。示例性地，定型部件50可以粘接于框体22，例如，定型部件50可以通过粘接剂或者双面胶带粘接于框体22。柔性的定型部件50具有良好的柔软度，从而电连接线40与定型部件50发生接触时，定型部件50与电连接线40之间不易发生磨损，降低因电连接线40长期受到定型部件50磨损而导致电连接线40发生结构损坏或者断线失效的可能性。示例性地，定型部件50的材料可以是泡棉。
