Description
本申请要求于2019年07月31日提交中国专利局、申请号为2019107019088、申请名称为“折叠组件及电子设备”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。
本申请涉及可折叠电子产品技术领域,尤其涉及一种折叠组件以及一种电子设备。
随着柔性显示屏的大规模运用,可折叠式的电子设备(例如手机)应运而生。电子设备具有依次连接的第一平面区域、弯折区域以及第二平面区域,弯折区域能够发生形变,以使第一平面区域相对第二平面区域展开或折叠。电子设备处于展开状态时,能够实现大屏显示。电子设备处于折叠状态时,便于收纳和携带。
柔性显示屏包括位于弯折区域的弯曲部分。由于柔性显示屏本身的强度及刚度较弱,电子设备处于折叠状态时,若用户对柔性显示屏的弯曲部分进行按压操作、或者用户握持电子设备而对柔性显示屏的弯曲部分施力,则柔性显示屏的弯曲部分容易因得不到支撑而发生塌陷、进而导致损坏,电子设备的用户体验较差。
发明内容
本申请提供一种能够支撑柔性显示屏的弯曲部分的折叠组件、以及一种应用该折叠组件的电子设备。
第一方面,本申请提供一种折叠组件。折叠组件可应用于具有柔性显示屏的电子设备中。折叠组件包括第一壳体、第二壳体及转轴组件,转轴组件连接在第一壳体与第二壳体之间。转轴组件能够发生形变,以使第一壳体相对第二壳体折叠或展开。
第一壳体包括第一主壳部及第一支撑部,第一支撑部连接于第一主壳部靠近转轴组件的一侧,第二壳体包括第二主壳部及第二支撑部,第二支撑部连接于第二主壳部靠近转轴组件的一侧。
第一主壳部用于支撑柔性显示屏的第一平直部分,第二主壳部用于支撑柔性显示屏的第二平直部分。在第一壳体相对第二壳体处于折叠状态时,第一支撑部及第二支撑部用于共同支撑柔性显示屏的弯曲部分。其中,柔性显示屏的弯曲部分连接在柔性显示屏的第一平直部分与柔性显示屏的第二平直部分之间。
在本申请中,在第一壳体相对第二壳体处于折叠状态时,第一支撑部与第二支撑部能够共同支撑柔性显示屏的弯曲部分,辅助柔性显示屏的弯曲部分维持一个较为稳定的形状,因此柔性显示屏的弯曲部分受到外力时(例如用户对柔性显示屏的弯曲部分进行按压、触摸等操作,或者用户握持电子设备而对柔性显示屏的弯曲部分施力),发生塌陷或内凹的风险较低,柔性显示屏的可靠性较高,使用寿命较长,同时也提高了柔性显示屏的观感和手 感。
第一主壳部为柔性显示屏的第一平直部分提供支撑,第二主壳部为柔性显示屏的第二平直部分提供支撑,使得柔性显示屏的第一平直部分和第二平直部分受到外力时(例如用户触摸、意外碰撞等),发生塌陷或内凹的风险较低,柔性显示屏的可靠性较高,使用寿命较长。
可以理解的是,第一主壳部对柔性显示屏的第一平直部分的支撑可以是直接支撑(例如接触并支撑),也可以是间接支撑(例如通过中间结构件支撑)。第二主壳部对柔性显示屏的第二平直部分的支撑可以是直接支撑,也可以是间接支撑。第一支撑部和第二支撑部对柔性显示屏的弯曲部分的支撑可以是直接支撑,也可以是间接支撑。
一些实施例中,第一支撑部具有第一支撑面。第二支撑部具有第二支撑面。第一支撑面及第二支撑面均为弧面。在第一壳体相对第二壳体处于折叠状态时,第一支撑面的中心线与第二支撑面的中心线重合。
在本实施例中,在第一壳体相对第二壳体处于折叠状态时,第一支撑面和第二支撑面用于共同支撑柔性显示屏的弯曲部分。在第一壳体相对第二壳体处于折叠状态时,由于第一支撑面及第二支撑面均为弧面,且第一支撑面的中心线与第二支撑面的中心线重合,因此第一支撑面和第二支撑面所在面重合,从而能够连续地、平滑地支撑柔性显示屏的弯曲部分,支撑效果更佳。
在本申请实施例中,第一支撑面和第二支撑面的形状可以依据柔性显示屏的弯曲部分在第一壳体相对第二壳体处于折叠状态时的形状进行仿形设计,使得第一支撑面和第二支撑面能够在第一壳体相对第二壳体处于折叠状态时,为柔性显示屏的弯曲部分提供仿形支撑,支撑效果更好,以降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险,提高柔性显示屏的可靠性和使用寿命。例如:
一些实施例中,第一壳体相对第二壳体处于折叠状态时,柔性显示屏的弯曲部分可以为半圆形。第一支撑面和第二支撑面可以为圆弧面。此时,第一支撑面和第二支撑面在第一壳体相对第二壳体处于折叠状态时,其圆心重合,位于同一个圆柱面中。
另一些实施例中,第一壳体相对第二壳体处于折叠状态时,柔性显示屏的弯曲部分可以为半椭圆形。第一支撑面和第二支撑面可以为椭圆弧面。此时,第一支撑面和第二支撑面在第一壳体相对第二壳体处于折叠状态时,其圆心重合,位于同一个椭圆柱面中。
在其他一些实施例中,柔性显示屏的弯曲部分也可以设置成其他形状,例如,柔性显示屏的弯曲部分也可以包括平面段和两个弧面段,一个弧面段连接在柔性显示屏的第一平直部分与平面段之间,另一个弧面段连接在柔性显示屏的第二平直部分与平面段之间。第一支撑面和第二支撑面依据柔性显示屏的弯曲部分于折叠状态的形状进行设置。
在本申请实施例中,第一支撑部的结构设计可以有多种方式,例如:
一些实施例中,第一支撑部呈长条形。第一支撑部的延伸方向平行于转轴组件的转动轴线。在本实施例中,第一支撑部沿平行于转轴组件的转动轴线的方向连续地支撑柔性显示屏的弯曲部分,支撑面积较大,支撑效果较佳。
示例性的,第二支撑部呈长条形。第一支撑部的延伸方向平行于转轴组件的转动轴线。第二支撑部沿平行于转轴组件的转动轴线的方向连续地支撑柔性显示屏的弯曲部分,支撑 面积较大,支撑效果较佳。示例性的,第一支撑部与第二支撑部对称设置。
示例性的,第一支撑部可设置若干个彼此间隔排布的通孔或者凹槽,以减轻第一支撑部的质量,有利于电子设备的轻薄化。第一支撑部设置凹槽时,凹槽的开口位于第一支撑部背向柔性显示屏的一侧。
另一些实施例中,第一支撑部包括间隔排布的多个第一支撑块。多个第一支撑块的排布方向平行于转轴组件的转动轴线。在本实施例中,在第一壳体相对第二壳体处于折叠状态时,第一支撑部能够支撑柔性显示屏的弯曲部分,且质量较轻,有利于电子设备的轻薄化。
示例性的,第二支撑部包括间隔排布的多个第二支撑块。多个第二支撑块的排布方向平行于转轴组件的转动轴线。多个第二支撑块与多个第一支撑块一一正对设置。其他示例中,第二支撑部的多个第二支撑块与第一支撑部的多个第一支撑块错开排布。也即,第二支撑块正对相邻的两个第一支撑块之间的间隙。第一支撑块正对两个第二支撑块之间的间隙。此时,第一支撑部和第二支撑部相配合后,对柔性显示屏的弯曲部分的支撑区域排布更为均衡,有利于降低柔性显示屏的弯曲部分在受到外力时发生塌陷或内凹的风险。
一些实施例中,转轴组件包括一个或多个转动件,转动件的两端能够相对转动。转动件的两端分别连接第一主壳部和第二主壳部。第一支撑部及第二支撑部均与转动件彼此错开排布。在本实施例中,第一支撑部和第二支撑部以及转动件在电子设备的厚度方向上无堆叠关系,大致平铺于电子设备的弯折区域,有利于降低电子设备于弯折区域处的厚度,以实现轻薄化。
一些实施例中,折叠组件具有布线空间。布线空间用于排布电子设备的柔性电路板等连线。电子设备的连线还可以包括用于传输天线信号的同轴线等。布线空间包括依次连通的第一内腔、第一空间、连通空间、第二空间及第二内腔。第一内腔位于第一主壳部。第一空间对应于第一支撑部。第一支撑部形成第一空间的部分壁面。第二空间对应于第二支撑部。第二支撑部形成第二空间的部分壁面。第二内腔位于第二主壳部。
在本实施例中,电子设备的柔性电路板排布于布线空间,以横跨第一支撑部和第二支撑部,且柔性电路板的两端分别收容于第一主壳部内侧和第二主壳部内侧,从而连接位于第一主壳部内侧的元器件与位于第二主壳部内侧的元器件。由于第一支撑部和第二支撑部为电子设备的壳体结构,在满足支撑柔性显示屏的弯曲部分的情况下,第一支撑部和第二支撑部能够设置成体积较小的结构,以减少其占用的空间,从而能够在第一支撑部和第二支撑部附近预留足够的空间(例如第一支撑部下方和第二支撑部下方的空间),以作为布线空间的一部分,使得电子设备的柔性电路板能够经布线空间,自第一主壳部延伸至第二主壳部,从而实现信号传输。
示例性的,第一支撑部和第二支撑部可以设置成弧形臂状结构,以减小体积及占用空间。例如,第一支撑部还包括第一内侧面。第一内侧面与第一支撑面相背设置。第一内侧面与第一支撑面之间的距离为第一支撑部的厚度,第一支撑部为等厚结构。此时,第一支撑部大致呈弯折的板状结构。第二支撑部的结构参考第一支撑部的结构设置。
一些实施例中,折叠组件还包括第一滑板、第二滑板及转动连接件。转动连接件连接在第一滑板与第二滑板之间,转动连接件能够发生形变,以使第一滑板相对第二滑板折叠 或展开,第一滑板滑动连接第一主壳部,第二滑板滑动连接第二主壳部。
在本实施例中,第一壳体相对第二壳体展开时,第一滑板相对第二滑板展开。第一壳体相对第二壳体折叠时,第一滑板相对第二滑板折叠。滑板组件位于柔性电路板及转轴组件远离柔性显示屏的一侧。换言之,柔性电路板及转轴组件位于滑板组件与柔性显示屏之间,为电子设备的内部结构,而被隐藏和保护。
一些实施例中,第一支撑部与第一滑板之间形成第一空间,第二支撑部与第二滑板之间形成第二空间。
在本实施例中,由于第一支撑部与第一滑板均可设置成厚度较小的结构,因此第一空间的容积较大。同样的,由于第二支撑部与第二滑板均可设置成厚度较小的结构,因此第二空间的容积较大。因此,布线空间较大,能够为柔性电路板的走线和形变提供足够的空间。
一些实施例中,转轴组件还包括连接件。转轴组件的转动件的数量为多个,多个转动件间隔排布且排布方向平行于转轴组件的转动轴线。连接件连接多个转动件。
在本实施例中,转轴组件的多个部件组装呈一体式结构,使得转轴组件的稳定性和牢固度更佳,电子设备在折叠和展开过程中的转动动作稳定性更好、更为可靠。
一些实施例中,连接件与第一滑板及第二滑板之间形成连通空间。在本实施例中,由于连接件的体积较小,因此连通空间的容积较大,布线空间能够为柔性电路板的走线和形变提供足够的空间。
一些实施例中,连接件具有第三支撑面。第三支撑面位于连接件远离第一滑板及第二滑板的一侧,第三支撑面用于支撑柔性显示屏的弯曲部分。在本实施例中,连接件通过第三支撑面支撑柔性显示屏的弯曲部分,以降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险。
一些实施例中,第三支撑面呈弧面。在第一壳体相对第二壳体处于折叠状态时,第三支撑面的中心线与第一支撑面的中心线重合。在本实施例中,第一支撑面、第二支撑面以及第三支撑面共同支撑柔性显示屏的弯曲部分,且用于支撑柔性显示屏的弯曲部分的多个支撑面的总面积更大、支撑面一致性好,能够对折叠状态下的柔性显示屏的弯曲部分提供连续且平滑的支撑,使得柔性显示屏的弯曲部分的手感更高、可靠性更高。
一些实施例中,转动件具有第四支撑面。第四支撑面用于支撑柔性显示屏的弯曲部分。在本实施例中,转动件通过第四支撑面支撑柔性显示屏的弯曲部分,以降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险。
示例性的,第四支撑面呈弧面。在第一壳体相对第二壳体处于折叠状态时,第四支撑面的中心线与第一支撑面的中心线重合。此时,第一支撑面、第二支撑面以及第四支撑共同支撑柔性显示屏的弯曲部分,且用于支撑柔性显示屏的弯曲部分的多个支撑面的总面积更大、支撑面一致性好,能够对折叠状态下的柔性显示屏的弯曲部分提供连续且平滑的支撑,辅助柔性显示屏的弯曲部分维持一个较为稳定的形状,从而降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险,使得柔性显示屏的弯曲部分的手感更高、可靠性更高。
一些实施例中,折叠组件还包括弯折支撑件。弯折支撑件包括第一侧部和远离第一侧 部的第二侧部。弯折支撑件能够发生形变,以使第一侧部相对第二侧部折叠或展开。
第一侧部连接第一主壳部,第二侧部连接第二主壳部,弯折支撑件用于支撑柔性显示屏的部分第一平直部分、柔性显示屏的弯曲部分以及柔性显示屏的部分第二平直部分。
在本实施例中,弯折支撑件覆盖转轴组件、第一支撑部及第二支撑部。弯折支撑件用于支撑柔性显示屏。由于弯折支撑件为连续的一体式结构,因此能够为柔性显示屏提供连续的、平滑的支撑,使得柔性显示屏的观感及手感更佳。
示例性的,弯折支撑件的中部与柔性显示屏的弯曲部分的中部固定连接(例如粘接)。弯折支撑件的中部与转轴组件固定连接。在本实施例中,柔性显示屏与转轴组件相固定,当第一壳体相对第二壳体转动时,柔性显示屏的弯曲部分的中部随转轴组件移动,从而减小柔性显示屏的弯曲部分出现脱胶的几率,降低柔性显示屏出现拱起问题的风险。
一些实施例中,弯折支撑件包括柔性基底及彼此间隔地固定于柔性基底的多个支撑条。各支撑条的延伸方向平行于转轴组件的转动轴线,多个支撑条的排布方向垂直于转轴组件的转动轴线。第一侧部固定连接第一主壳部,第二侧部固定连接第二主壳部。
在本实施例中,柔性基底使得弯折支撑件具有一定的柔韧性,使得弯折支撑件的最大弯折角度能够满足折叠组件的折叠要求。由于支撑条能够增加弯折支撑件的刚度,使得弯折支撑件具有良好的支撑性能。
示例性的,支撑条的刚度大于柔性基底的刚度。支撑条可以采用不锈钢、铝合金等金属材料,或者也可以采用硬质的塑料,例如聚氯乙烯。柔性基底可采用具有较高柔韧性的硅胶材料。
一些实施例中,多个支撑条包括第一支撑条和第二支撑条。在第一壳体相对第二壳体处于折叠状态时,第一支撑条搭设于第一支撑部与转轴组件,第二支撑条搭设于第二支撑部与转轴组件。
在本实施例中,在第一壳体相对第二壳体处于折叠状态时,第一支撑部、弯折支撑件、转轴组件以及第二支撑部相互配合,能够对柔性显示屏的弯曲部分起到连续的刚性支撑,使得柔性显示屏的弯曲部分维持一个较为稳定的形状,从而降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险。
一些实施例中,弯折支撑件采用弹性金属材料。弯折支撑件呈面状或者网格状。第一侧部滑动连接第一主壳部,第二侧部滑动连接第二主壳部。在本实施例中,弯折支撑件能够为柔性显示屏提供连续、平滑且强度较高的支撑,使得柔性显示屏的观感及手感更佳。
第二方面,本申请实施例还提供一种电子设备,包括柔性显示屏和上述任一项中的折叠组件。在本实施例中,由于折叠组件能够在电子设备处于折叠状态时,对柔性显示屏的弯曲部分提供支撑,以降低柔性显示屏的弯曲部分受到外力时发生塌陷或内凹的风险,使得电子设备的可靠性更高。
一些实施例中,电子设备还包括柔性电路板。柔性电路板横跨第一支撑部和第二支撑部,且柔性电路板的两端分别收容于第一主壳部内侧和第二主壳部内侧。在本实施例中,电子设备的柔性电路板排布于折叠组件的布线空间,从而连接位于第一主壳部内侧的元器件与位于第二主壳部内侧的元器件。

下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请实施例提供一种电子设备。电子设备可以是手机、平板电脑、笔记本电脑、可穿戴显示设备等可折叠设备。
请一并参阅图1和图2,图1是本申请一实施例提供的电子设备100处于展开状态的结构示意图;图2是图1所示电子设备100处于折叠状态的结构示意图。图1所示电子设备100以手机为例进行说明。
电子设备100包括依次连接的第一平面区域1001、弯折区域1002以及第二平面区域1003。弯折区域1002能够发生形变,以使第一平面区域1001相对第二平面区域1003展开或折叠。如图1所示,第一平面区域1001相对第二平面区域1003展开,电子设备100处于展开状态。如图2所示,第二平面区域1003相对第二平面区域1003折叠,电子设备100处于折叠状态。弯折区域1002形变时,第一平面区域1001和第二平面区域1003能够绕弯折区域1002的转动轴线1004转动。其中,定义电子设备100的宽度方向X垂直于弯折区域1002的转动轴线1004,电子设备100的长度方向Y平行于弯折区域1002的转动轴线1004,电子设备100的厚度方向Z垂直在于电子设备100的宽度方向X及长度方向Y。
电子设备100包括柔性显示屏10及折叠组件20。柔性显示屏10安装于折叠组件20。柔性显示屏10用于显示图像、视频等。柔性显示屏10能够弯折。折叠组件20的两部分能够相对转动,以带动柔性显示屏10折叠或展开。其中,电子设备100为屏幕外折结构。如图2所示,电子设备100处于折叠状态时,柔性显示屏10位于折叠组件20外侧,而外露 于电子设备100外侧,用户能够在电子设备100处于折叠状态时,触摸柔性显示屏10。
柔性显示屏10包括第一平直部分101、弯曲部分102及第二平直部分103。柔性显示屏10的弯曲部分102连接在柔性显示屏10的第一平直部分101与柔性显示屏10的第二平直部分103之间。柔性显示屏10的第一平直部分101位于第一平面区域1001。柔性显示屏10的弯曲部分102位于弯折区域1002。柔性显示屏10的第二平直部分103位于第二平面区域1003。如图1所示,电子设备100处于展开状态时,柔性显示屏10的第一平直部分101、弯曲部分102及第二平直部分103可以同时显示,以实现大屏显示,以提高用户的观看体验。如图2所示,电子设备100处于折叠状态时,电子设备100在其宽度方向X上的尺寸缩小,电子设备100便于收纳和携带。此时,柔性显示屏10的第一平直部分101、柔性显示屏10的弯曲部分102及柔性显示屏10的第二平直部分(图2中未示出)中的一者或多者能够进行显示。例如,柔性显示屏10的弯曲部分102进行显示,实现电子设备100的侧边显示。柔性显示屏10的第一平直部分101或柔性显示屏10的第二平直部分进行显示,实现电子设备100的单侧显示。其中,柔性显示屏10可以集成触控功能。电子设备100可以响应于用户触摸柔性显示屏10的手势,唤醒柔性显示屏10的相应部分。
示例的,柔性显示屏10可以是有机发光二极管(organic light-emitting diode,OLED)显示屏,有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light-emitting diode,AMOLED)显示屏、迷你发光二极管(mini organic light-emitting diode)显示屏、微型发光二极管(micro organic light-emitting diode)显示屏、微型有机发光二极管(micro organic light-emitting diode)显示屏、量子点发光二极管(quantum dot light emitting diodes,QLED)显示屏等。
请一并参阅图3和图4,图3是图1所示电子设备100的部分结构的分解示意图,图4是图1所示电子设备100的部分结构的正视图。其中,图4中电子设备100的结构与图3中电子设备100的结构相对应。
折叠组件20包括第一壳体1、第二壳体2及转轴组件3。转轴组件3连接在第一壳体1与第二壳体2之间。转轴组件3能够发生形变,以使第一壳体1相对第二壳体2折叠或展开。第一壳体1和第二壳体2能够绕转轴组件3的转动轴线31转动。转轴组件3的转动轴线31可以与电子设备100的弯折区域1002的转动轴线1004(参阅图1)重合。
第一壳体1包括第一主壳部11及第一支撑部12。第一支撑部12连接于第一主壳部11靠近转轴组件3的一侧。第一主壳部11位于电子设备100的第一平面区域1001,第一支撑部12延伸至电子设备100的弯折区域1002。第二壳体2包括第二主壳部21及第二支撑部22。第二支撑部22连接于第二主壳部21靠近转轴组件3的一侧。第二主壳部21位于电子设备100的第二平面区域1003,第二支撑部22延伸至电子设备100的弯折区域1002。换言之,第一支撑部12和第二支撑部22位于第一主壳部11与第二主壳部21之间。
一些实施例中,如图3和图4所示,转轴组件3可以包括一个或多个转动件32。本申请实施例中,“多个”是指至少两个。转动件32的两端能够相对转动。各转动件32的两端分别连接第一主壳部11和第二主壳部21。转动件32的两端相对转动时,第一主壳部11与第二主壳部21同步地相对转动。本实施例中,以转轴组件3包括两个转动件32为例进行说明。两个转动件32彼此间隔地排布,且排布方向平行于转轴组件3的转动轴线31, 使得第一壳体1和第二壳体2在相对转动的过程中,受力较为均衡,转动过程更稳平稳。示例性的,两个转动件32分别排布于电子设备100的弯折区域1002的顶端位置和底端位置处。
一些实施例中,如图3和图4所示,第一支撑部12及第二支撑部22均与转动件32彼此错开排布。此时,第一支撑部12和第二支撑部22以及转动件32在电子设备100的厚度方向Z上无堆叠关系,大致平铺于电子设备100的弯折区域1002,有利于降低电子设备100于弯折区域1002处的厚度,以实现轻薄化。一些实施例中,第一支撑部12与第二支撑部22位于两个转动件32之间。
其他一些实施例中,转动件32的数量可以为一个。转动件32位于电子设备100的弯折区域1002的中部位置。第一支撑部12位于转动件32的一侧或两侧,第二支撑部22分位于转动件32的一侧或两侧。
其他一些实施例中,转动件32的数量可以为三个。三个转动件32彼此间隔地排布,且排布方向平行于转轴组件3的转动轴线31。第一支撑部12和第二支撑部22可以排布于相邻的两个转动件32之间。
一些实施例中,如图3和图4所示,转轴组件3还包括连接件33。转轴组件3的转动件32的数量为多个。多个转动件32间隔排布且排布方向平行于转轴组件3的转动轴线31。连接件33连接多个转动件32。示例性的,转动件32的数量为两个,连接件33连接在两个转动件32之间。此时,转轴组件3的多个部件组装呈一体式结构,使得转轴组件3的稳定性和牢固度更佳,电子设备100在折叠和展开过程中的转动动作稳定性更好、更为可靠。
一些实施例中,如图3和图4所示,连接件33呈条形。连接件33的延伸方向平行于或大致平行于转轴组件3的转动轴线31。连接件33的两端分别连接两个转动件32。示例性的,第一支撑部12和第二支撑部22位于连接件33的两侧。由于连接件33的体积较小,占用空间较小,因此将第一支撑部12和第二支撑部22设于连接件33的两侧,既能够降低连接件33与第一支撑部12及第二支撑部22之间发生干涉的风险,也能够提高电子设备100的弯折区域1002的空间利用率,有利于电子设备100的轻薄化。
另一些实施例中,转动件32为三个以上(包括本数)时,连接件33可以为一体结构,连接件33同时连接所有转动件32;连接件33也可以为分体结构,包括多段连接部,相邻的两个连接件33之间均通过连接部连接,从而将多个连接件33串联成一体结构。此时,第一支撑部12和第二支撑部22也可以为多段结构,分别对应地设置在多段连接段的两侧。
再一些实施例中,与前述实施例不同的是,转轴组件3也可以不设置连接件33,转轴组件3的多个转动件32彼此独立设置。此时,若转轴组件3中的某个转动件32发生故障,则只需对故障转动件32进行维修或更换,电子设备100的维修成本较低,且效率较高。
一些实施例中,如图3和图4所示,电子设备100还包括多个元器件30。多个元器件30收容在第一主壳部11和第二主壳部21内侧。多个元器件30在第一主壳部11和第二主壳部21中的排布方式有多种,本申请对此不作严格限定。多个元器件30可以包括电路板、处理器、存储器、电池、摄像模组、传感器模组、音频模组、指纹模组、无线通信模组、移动通信模组、马达模组等中的多者。处理器和存储器可固定于电路板。柔性显示屏10、存储器、电池以及摄像模组等模组耦合处理器。
一些实施例中,如图3和图4所示,电子设备100还可以包括柔性电路板40。柔性电路板40自第一壳体1延伸至第二壳体2。柔性电路板40用于电连接分别位于第一主壳部11和第二主壳部21的两个元器件30。例如,柔性电路板40电连接位于第一主壳部11的第一电路板和位于第二主壳部21的第二电路板。柔性电路板40的数量可以为一个或多个。
一些实施例中,如图3和图4所示,折叠组件20还包括第一滑板501、第二滑板502及转动连接件503。第一滑板501、第二滑板502及转动连接件503形成滑板组件50。转动连接件503连接在第一滑板501与第二滑板502之间。转动连接件503能够发生形变,以使第一滑板501相对第二滑板502折叠或展开。第一滑板501滑动连接第一主壳部11。第二滑板502滑动连接第二主壳部21。第一壳体1相对第二壳体2展开时,第一滑板501相对第二滑板502展开。第一壳体1相对第二壳体2折叠时,第一滑板501相对第二滑板502折叠。滑板组件50位于柔性电路板40及转轴组件3远离柔性显示屏10的一侧。换言之,柔性电路板40及转轴组件3位于滑板组件50与柔性显示屏10之间,为电子设备100的内部结构,而被隐藏和保护。
示例性的,如图3和图4所示,转动连接件503与转轴组件3的连接件33错开排布。例如,转动连接件503排布于两个连接件33之间。转动连接件503的数量可以为一个或多个。例如,转动连接件503的数量为两个。两个转动连接件503间隔排布且排布方向平行于转轴组件3的转动轴线31,此时,第一滑板501和第二滑板502通过转动连接件503进行折叠或展开时的动作更为平稳。
另一些实施例中,与前述实施例不同的是,电子设备100不设置滑板组件50。电子设备100包括能够发生形变的遮挡件。遮挡件的一端连接第一主壳部11,遮挡件的另一端连接第二主壳部21。遮挡件的两端能够相对弯折。示例性的,遮挡件可以为弹性板或柔性板,包括多个折叠部分,遮挡件通过多个折叠部分的展开或折叠动作,实现变形。
请一并参阅图5和图6,图5是图1所示电子设备100在A1-A1线处的部分结构的剖视图;图6是图2所示电子设备100在A2-A2线处的部分结构的剖视图。其中,图1的A1-A1线所在平面与图2的A2-A2线所在平面为同一平面。图4的A3-A3线所在平面与图1的A1-A1线所在平面亦为同一平面。
如图5和图6所示,第一主壳部11用于支撑柔性显示屏10的第一平直部分101。第二主壳部21用于支撑柔性显示屏10的第二平直部分103。此时,第一主壳部11为柔性显示屏10的第一平直部分101提供支撑,第二主壳部21为柔性显示屏10的第二平直部分103提供支撑,使得柔性显示屏10的第一平直部分101和第二平直部分103受到外力时(例如用户触摸、意外碰撞等),发生塌陷或内凹的风险较低,柔性显示屏10的可靠性较高,使用寿命较长。可以理解的是,第一主壳部11对柔性显示屏10的第一平直部分101的支撑可以是直接支撑(例如接触并支撑),也可以是间接支撑(例如通过中间结构件支撑)。同样的,第二主壳部21对柔性显示屏10的第二平直部分103的支撑可以是直接支撑,也可以是间接支撑。
如图6所示,在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12及第二支撑部22用于共同支撑柔性显示屏10的弯曲部分102。可以理解的是,第一支撑部12和第二支撑部22对柔性显示屏10的弯曲部分102的支撑可以是直接支撑,也可以是间接支撑。 电子设备100处于折叠状态时,第一壳体1相对第二壳体2处于折叠状态。
在本实施例中,在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12与第二支撑部22能够共同支撑柔性显示屏10的弯曲部分102,辅助柔性显示屏10的弯曲部分102维持一个较为稳定的形状,因此柔性显示屏10的弯曲部分102受到外力时(例如用户对柔性显示屏10的弯曲部分102进行按压、触摸等操作,或者用户握持电子设备100而对柔性显示屏10的弯曲部分102施力),发生塌陷或内凹的风险较低,柔性显示屏10的可靠性较高,使用寿命较长,同时也提高了柔性显示屏10的观感和手感。
一些实施例中,如图6所示,第一支撑部12具有第一支撑面121。第二支撑部22具有第二支撑面221。第一支撑面121和第二支撑面221用于在第一壳体1相对第二壳体2处于折叠状态时,共同支撑柔性显示屏10的弯曲部分102。第一支撑面121及第二支撑面221均为弧面。在第一壳体1相对第二壳体2处于折叠状态时,第一支撑面121的中心线1211与第二支撑面221的中心线2211重合。此时,第一支撑面121及第二支撑面221能够连续地、平滑地支撑柔性显示屏10的弯曲部分102,支撑效果更佳。
示例性的,第一支撑面121及第二支撑面221的半径相等。此时,第一支撑面121和第二支撑面221所在面重合,第一支撑面121和第二支撑面221能够直接支撑柔性显示屏10的弯曲部分102,或者通过等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。其他示例中,第一支撑面121的半径与第二支撑面221的半径也可以不相等。此时,第一支撑面121和第二支撑面221能够通过不等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。本申请对此不做严格限定。
在本申请实施例中,第一支撑面121和第二支撑面221的形状可以依据柔性显示屏10的弯曲部分102在第一壳体1相对第二壳体2处于折叠状态时的形状进行仿形设计,使得第一支撑面121和第二支撑面221能够在第一壳体1相对第二壳体2处于折叠状态时,为柔性显示屏10的弯曲部分102提供仿形支撑,支撑效果更好,以降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险,提高柔性显示屏10的可靠性和使用寿命。
一些实施例中,如图6所示,第一壳体1相对第二壳体2处于折叠状态时,柔性显示屏10的弯曲部分102可以为半圆形。第一支撑面121和第二支撑面221可以为圆弧面。此时,第一支撑面121和第二支撑面221在第一壳体1相对第二壳体2处于折叠状态时,其圆心重合,位于同一个圆柱面中。
另一些实施例中,第一壳体1相对第二壳体2处于折叠状态时,柔性显示屏10的弯曲部分102可以为半椭圆形。第一支撑面121和第二支撑面221可以为椭圆弧面。此时,第一支撑面121和第二支撑面221在第一壳体1相对第二壳体2处于折叠状态时,其圆心重合,位于同一个椭圆柱面中。
在其他一些实施例中,柔性显示屏10的弯曲部分102也可以设置成其他形状,例如,柔性显示屏10的弯曲部分102也可以包括平面段和两个弧面段,一个弧面段连接在柔性显示屏10的第一平直部分101与平面段之间,另一个弧面段连接在柔性显示屏10的第二平直部分103与平面段之间。第一支撑面121和第二支撑面221依据柔性显示屏10的弯曲部分102于折叠状态的形状进行设置。本申请对柔性显示屏10的弯曲部分102的形状不作严格限定。
一些实施例中,如图5和图6所示,折叠组件20具有布线空间201。布线空间201用于排布电子设备100的柔性电路板40等连线。电子设备100的连线还可以包括用于传输天线信号的同轴线等。本实施例以电子设备100的柔性电路板40排布于布线空间201为例进行说明。
布线空间201包括依次连通的第一内腔2011、第一空间2012、连通空间2013、第二空间2014及第二内腔2015。第一内腔2011位于第一主壳部11。第一空间2012对应于第一支撑部12。第一支撑部12形成第一空间2012的部分壁面。第二空间2014对应于第二支撑部22。第二支撑部22形成第二空间2014的部分壁面。第二内腔2015位于第二主壳部21。第一内腔2011位于电子设备100的第一平面区域1001。连通空间2013位于电子设备100的弯折区域1002。第一空间2012连通第一内腔2011和连通空间2013,大致位于电子设备100的弯折区域1002靠近第一平面区域1001的位置处,随第一支撑部12的位置发生变化。第二内腔2015位于电子设备100的第二平面区域1003。第二空间2014连通第二内腔2015和连通空间2013,大致位于电子设备100的弯折区域1002靠近第二平面区域1003的位置处,随第二支撑部22的位置发生变化。
在本实施例中,柔性电路板40横跨第一支撑部12和第二支撑部22,且柔性电路板40的两端分别收容于第一主壳部11内侧和第二主壳部21内侧。由于第一支撑部12和第二支撑部22为电子设备100的壳体结构,在满足支撑柔性显示屏10的弯曲部分102的情况下,第一支撑部12和第二支撑部22能够设置成体积较小的结构,以减少其占用的空间,从而能够在第一支撑部12和第二支撑部22附近预留足够的空间(例如第一支撑部12下方和第二支撑部22下方的空间),以作为布线空间201的一部分,使得电子设备100的柔性电路板40能够经布线空间201,自第一主壳部11延伸至第二主壳部21,从而实现信号传输。
示例性的,如图5和图6所示,第一支撑部12和第二支撑部22设置弧形臂状结构,以减小体积及占用空间。例如,第一支撑部12还包括第一内侧面122。第一内侧面122与第一支撑面121相背设置。第一内侧面122与第一支撑面121之间的距离为第一支撑部12的厚度,第一支撑部12为等厚结构。此时,第一支撑部12大致呈弯折的板状结构。第二支撑部22的结构参考第一支撑部12的结构设置。其他一些实施例中,第一支撑部12和第二支撑部22也可以设置成其他结构。
可以理解的是,结合图3和图4,转轴组件3的转动件32体积较大,且其所需要的转动空间较大,因此布线空间201错开转动件32排布,布线空间201与转动件32在电子设备100的弯折区域1002的位置不同,使得电子设备100的弯折区域1002的整体厚度能够设置成较小值,从而有利于电子设备100的轻薄化。
示例性的,如图5和图6所示,第一支撑部12与第一滑板501之间形成第一空间2012。第二支撑部22与第二滑板502之间形成第二空间2014。由于第一支撑部12与第一滑板501均可设置成厚度较小的结构,因此第一空间2012的容积较大。同样的,由于第二支撑部22与第二滑板502均可设置成厚度较小的结构,因此第二空间2014的容积较大。因此,布线空间201较大,能够为柔性电路板40的走线和形变提供足够的空间。其他一些实施例中,电子设备100不设置滑板组件50,而设置遮挡件时,遮挡件与第一支撑部12之间形成第一空间2012,与第二支撑部22之间形成第二空间2014。此时,遮挡件也尽量采用体 积较小的结构,以使第一空间2012和第二空间2014的容积较大。
示例性的,如图5和图6所示,连接件33与第一滑板501及第二滑板502之间形成连通空间2013。此时,柔性电路板40依次穿过第一支撑部12与第一滑板501之间的空间、连接件33与第一滑板501及第二滑板502之间的空间、以及第二支撑部22与第二滑板502之间的空间。由于连接件33的体积较小,因此连通空间2013的容积较大,布线空间201能够为柔性电路板40的走线和形变提供足够的空间。其他一些实施例中,电子设备100未设置连接件33,则柔性显示屏10的弯曲部分102与第一滑板501及第二滑板502之间形成连通空间2013。其他一些实施例中,电子设备100不设置滑板组件50,而设置遮挡件时,遮挡件与连接件33或柔性显示屏10的弯曲部分102之间形成连通空间2013。
一些实施例中,如图5和图6所示,连接件33具有第三支撑面331。第三支撑面331位于连接件33远离第一滑板501及第二滑板502的一侧。第三支撑面331用于支撑柔性显示屏10的弯曲部分102。在本实施例中,连接件33通过第三支撑面331支撑柔性显示屏10的弯曲部分102,以降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险。
如图6所示,在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12、第二支撑部22以及连接件33能够共同支撑柔性显示屏10的弯曲部分102,折叠组件20对柔性显示屏10的支撑面面积较大,能够辅助柔性显示屏10的弯曲部分102维持一个较为稳定的形状,从而降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险。
示例性的,如图6所示,第三支撑面331呈弧面。在第一壳体1相对第二壳体2处于折叠状态时,第三支撑面331的中心线3311与第一支撑面121的中心线1211重合。此时,第一支撑面121、第二支撑面221以及第三支撑面331共同支撑柔性显示屏10的弯曲部分102,支撑柔性显示屏10的弯曲部分102的多个支撑面的总面积更大、且支撑面一致性好,能够对折叠状态下的柔性显示屏10的弯曲部分102提供连续且平滑的支撑,使得柔性显示屏10的弯曲部分102的手感更高、可靠性更高。
示例性的,第三支撑面331的半径与第一支撑面121的半径相等。此时,第三支撑面331和第一支撑面121所在面重合,第三支撑面331和第一支撑面121能够直接支撑柔性显示屏10的弯曲部分102,或者通过等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。其他示例中,第三支撑面331的半径与第一支撑面121的半径也可以不相等。此时,第三支撑面331和第一支撑面121能够通过不等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。本申请对此不做严格限定。
可以理解的是,第三支撑面331的形状可以依据柔性显示屏10的弯曲部分102在第一壳体1相对第二壳体2处于折叠状态时的形状进行仿形设计,以提供更好的仿形支撑效果。
示例性的,如图5和图6所示,折叠组件20还包括第一固定件601和第二固定件602。柔性电路板40包括依次连接的第一固定区域、变形区域以及第二固定区域。第一固定件601收容于第一内腔2011。第一固定件601用于将柔性电路板40的第一固定区域固定于第一主壳部11。第二固定件602收容于第二内腔2015。第二固定件602用于将柔性电路板40的第二固定区域固定于第二主壳部21。
在本实施例中,由于柔性电路板40的第一固定区域与第一主壳部11相固定,柔性电 路板40的第二固定区域与第二主壳部21相固定,因此柔性电路板40的变形区域在第一壳体1相对第二壳体2转动的过程中发生变形时,能够在预设区域内活动,而避免发生位移、脱落等故障。
示例性的,第一固定件601和第二固定件602可以为胶材,也可以为紧固件或扣合结构件等,本申请对此不作严格限定。
请参阅图7和图8,图7是图1所示电子设备100在B1-B1线处的部分结构的剖视图;图8是图2所示电子设备100在B2-B2线处的部分结构的剖视图。其中,图1的B1-B1线所在平面与图2的B2-B2线所在平面为同一平面。图4的B3-B3线所在平面与图1的B1-B1线所在平面亦为同一平面。
一些实施例中,转动件32的两端分别连接第一主壳部11和第二主壳部21。转动件32可以为铰链结构、连杆结构、齿轮啮合结构等能够相对折叠和展开的结构。本申请对转动件32的具体结构不作严格限定。
一些实施例中,如图7和图8所示,转动件32具有第四支撑面321。第四支撑面321位于转动件32远离第一滑板501及第二滑板502的一侧。第四支撑面321用于支撑柔性显示屏10的弯曲部分102。在本实施例中,转动件32通过第四支撑面321支撑柔性显示屏10的弯曲部分102,以降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险。
示例性的,如图8所示,第四支撑面321呈弧面。在第一壳体1相对第二壳体2处于折叠状态时,第四支撑面321的中心线3211与第一支撑面121的中心线1211(参阅图6)共线。此时,第一支撑面121、第二支撑面221(参阅图6)以及第四支撑面321共同支撑柔性显示屏10的弯曲部分102,用于支撑柔性显示屏10的弯曲部分102的多个支撑面的总面积更大、且支撑面一致性好,能够对折叠状态下的柔性显示屏10的弯曲部分102提供连续且平滑的支撑,辅助柔性显示屏10的弯曲部分102维持一个较为稳定的形状,从而降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险,使得柔性显示屏10的弯曲部分102的手感更高、可靠性更高。
示例性的,第四支撑面321的半径与第一支撑面121(参阅图6)的半径相等。此时,第一支撑面121和第四支撑面321所在面重合,第一支撑面121和第四支撑面321能够直接支撑柔性显示屏10的弯曲部分102,或者通过等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。其他示例中,第四支撑面321的半径与第一支撑面121的半径也可以不相等。此时,第一支撑面121和第四支撑面321能够通过不等厚的中间结构件间接支撑柔性显示屏10的弯曲部分102。本申请对此不做严格限定。
可以理解的是,第四支撑面321的形状可以依据柔性显示屏10的弯曲部分102在第一壳体1相对第二壳体2处于折叠状态时的形状进行仿形设计,以提供更好的仿形支撑效果。
一些实施例中,如图7和图8所示,转动件32包括转动主体322和支撑件323。支撑件323可以为刚性结构。支撑件323与转动主体322的中部连接,例如可通过紧固件324连接。支撑件323位于转动主体322与柔性显示屏10之间。支撑件323远离所述转动主体322的表面为第四支撑面321。支撑件323可大致呈弧形板状结构。
在前述实施例中,如图7所示,由于支撑件323的第四支撑面321面积较大,因此支 撑件323占用空间较大,在第一壳体1相对第二壳体2处于展开状态时,支撑件323会对转动主体322的位置形成限制,转动主体322与支撑件323内侧接触的部分保持与支撑件323内侧相同的形状,转动主体322的活动空间受到一定的限制。其他一些实施例中,支撑件323设有若干缺口。在第一壳体1相对第二壳体2处于展开状态时,转动主体322部分嵌入缺口中,从而降低支撑件323对转动主体322活动空间的限制,使得转动主体322在折叠组件20的转动过程中更为灵活,转动件32的结构设计能够更为多样化。
其他一些实施例中,与前述实施例不同的是,转动件32未设置支撑件323,转动件32的转动主体322利用其自身的结构,在第一壳体1相对第二壳体2处于展开状态时,为柔性显示屏10的弯曲部分102提供平面支撑,在第一壳体1相对第二壳体2处于折叠状态时,为柔性显示屏10的弯曲部分102提供弧面支撑。
在本申请实施例中,第一支撑部12和第二支撑部22可以有多种实现方式。例如:
一些实施例中,如图3和图4所示,第一支撑部12呈长条形。第一支撑部12的延伸方向平行于转轴组件3的转动轴线31。第一支撑部12沿平行于转轴组件3的转动轴线31的方向连续地支撑柔性显示屏10的弯曲部分102,支撑面积较大,支撑效果较佳。
示例性的,第二支撑部22呈长条形。第一支撑部12的延伸方向平行于转轴组件3的转动轴线31。第二支撑部22沿平行于转轴组件3的转动轴线31的方向连续地支撑柔性显示屏10的弯曲部分102,支撑面积较大,支撑效果较佳。示例性的,第一支撑部12与第二支撑部22对称设置。
示例性的,第一支撑部12可设置若干个彼此间隔排布的通孔或者凹槽(图未示出),以减轻第一支撑部12的质量,有利于电子设备100的轻薄化。第一支撑部12设置凹槽时,凹槽的开口位于第一支撑部12背向柔性显示屏10的一侧。第二支撑部22的形状参阅第一支撑部12进行设置。
另一些实施例中,请参阅图9,图9是图1所示电子设备100的折叠组件20在另一实施例中的结构示意图。本实施例与前述实施例不同的是,第一支撑部12包括间隔排布的多个第一支撑块123。多个第一支撑块123的排布方向平行于转轴组件3的转动轴线31。此时,在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12能够支撑柔性显示屏的弯曲部分(图中未示出),且质量较轻,有利于电子设备100的轻薄化。
示例性的,多个第一支撑块123等间距排布。在平行于转轴组件3的转动轴线31的方向上,相邻两个第一支撑块123之间的间距小于第一支撑块123的长度。此时,第一支撑部12能够较好地支撑柔性显示屏的弯曲部分。多个第一支撑块123中每个第一支撑块123的长度可以彼此相同,也可以存在不同。可以理解的是,相邻两个第一支撑块123之间的间距、以及第一支撑块123的长度的具体尺寸,可以依据具体产品尺寸进行设计,使得处于折叠状态的电子设备100的弯折区域1002(参阅图1)在电子设备100的使用过程中不易发生塌陷或内凹现象。其他实施例中,多个第一支撑块123之间也可以不等间距排布,本申请对此不作严格限定。
示例性的,第二支撑部22包括间隔排布的多个第二支撑块223。多个第二支撑块223的排布方向平行于转轴组件3的转动轴线31。多个第二支撑块223与多个第一支撑块123一一正对设置。
再一些实施例中,请参阅图10,图10是图1所示电子设备100的折叠组件20在再一实施例中的结构示意图。本实施例与前述实施例不同的是,第二支撑部22的多个第二支撑块223与第一支撑部12的多个第一支撑块123错开排布。也即,第二支撑块223正对相邻的两个第一支撑块123之间的间隙。第一支撑块123正对两个第二支撑块223之间的间隙。此时,第一支撑部12和第二支撑部22相配合后,对柔性显示屏的弯曲部分的支撑区域排布更为均衡,有利于降低柔性显示屏的弯曲部分在受到外力时发生塌陷或内凹的风险。
一些实施例中,请参阅图11,图11是图1所示电子设备100的折叠组件20在再一实施例中的结构示意图。本实施例与前述实施例不同的是,折叠组件20还包括弯折支撑件4。弯折支撑件4包括第一侧部41和远离第一侧部41的第二侧部42。弯折支撑件4能够发生形变,以使第一侧部41相对第二侧部42折叠或展开。第一侧部41连接第一主壳部11。第二侧部42连接第二主壳部21。
示例性的,请参阅图12,图12是图11所示弯折支撑件4的仰视图。弯折支撑件4包括柔性基底441及彼此间隔地固定于柔性基底441的多个支撑条442。在本实施例中,柔性基底441使得弯折支撑件4具有一定的柔韧性,使得弯折支撑件4的最大弯折角度能够满足折叠组件20的折叠要求。由于支撑条442能够增加弯折支撑件4的刚度,使得弯折支撑件4具有良好的支撑性能。
示例性的,支撑条442的刚度大于柔性基底441的刚度。支撑条442可以采用不锈钢、铝合金等金属材料,或者也可以采用硬质的塑料,例如聚氯乙烯(polyvinyl chloride,PVC)。柔性基底441可采用具有较高柔韧性的硅胶材料。
支撑条442示例性的,如图12所示,各支撑条442的延伸方向平行于转轴组件3的转动轴线31。多个支撑条442的排布方向垂直于转轴组件3的转动轴线31。多个支撑条442的排布密度依据折叠组件20的支撑强度需求和弯折角度需求进行设计,本申请对此不作严格限定。
示例性的,如图12所示,弯折支撑件4还包括位于第一侧部41和第二侧部42之间的弯折中部43。多个支撑条442排布于第一侧部41、弯折中部43及第二侧部42。其中,排布于折弯中部的支撑条442的宽度(于电子设备100的宽度方向X上的尺寸)小于排布于第一侧部41和第二侧部42的支撑条442的宽度(于电子设备100的宽度方向X上的尺寸)。排布于折弯中部的多个支撑条442的宽度相等,且等间距排布。
一些实施例中,请一并参阅图13和图14,图13是图1所示电子设备100在A1-A1线处的部分结构在另一实施例中的剖视图;图14是图2所示电子设备100在A2-A2线处的部分结构在另一实施例中的剖视图。图14所示实施例与图13所示实施例对应。其中,图1的A1-A1线所在平面与图2的A2-A2线所在平面为同一平面。图11的A4-A4线所在平面与图1的A1-A1线所在平面亦为同一平面。
弯折支撑件4用于支撑柔性显示屏10的部分第一平直部分101、柔性显示屏10的弯曲部分102以及柔性显示屏10的部分第二平直部分103。弯折支撑件4的第一侧部41固定连接第一主壳部11,第二侧部42固定连接第二主壳部21。在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12和第二支撑部22通过弯折支撑件4间接支撑柔性显示屏10的弯曲部分102。
在本实施例中,弯折支撑件4覆盖转轴组件(图中未示出)、第一支撑部12及第二支撑部22。弯折支撑件4用于支撑柔性显示屏10。由于弯折支撑件4为连续的一体式结构,因此能够为柔性显示屏10提供连续的、平滑的支撑,使得柔性显示屏10的观感及手感更佳。
示例性的,如图14所示,多个支撑条442包括第一支撑条442a和第二支撑条442b。在第一壳体1相对第二壳体2处于折叠状态时,第一支撑条442a搭设于第一支撑部12与转轴组件3(例如连接件33)。也就是说,第一支撑条442a的两侧分别正对第一支撑部12和连接件33,以横跨第一支撑部12与连接件33之间的间隙。第二支撑条442b搭设于第二支撑部22与转轴组件3(例如连接件33)。也就是说,第二支撑条442b的两侧分别正对第二支撑部22和连接件33,以横跨第二支撑部22与连接件33之间的间隙。
在本实施例中,在第一壳体1相对第二壳体2处于折叠状态时,第一支撑部12、弯折支撑件4、转轴组件3(例如连接件33)以及第二支撑部22相互配合,能够对柔性显示屏10的弯曲部分102起到连续的刚性支撑,使得柔性显示屏10的弯曲部分102维持一个较为稳定的形状,从而降低柔性显示屏10的弯曲部分102受到外力时发生塌陷或内凹的风险。
示例性的,如图13和图14所示,弯折支撑件4的中部与柔性显示屏10的弯曲部分102的中部固定连接(例如粘接)。弯折支撑件4的中部与转轴组件3固定连接。在本实施例中,柔性显示屏10与转轴组件3相固定,当第一壳体1相对第二壳体2转动时,柔性显示屏10的弯曲部分102的中部随转轴组件3移动,从而减小柔性显示屏10的弯曲部分102出现脱胶的几率,降低柔性显示屏10出现拱起问题的风险。
示例性的,如图12和图13所示,柔性基底441包括第一表面4411和与第一表面4411相背设置的第二表面4412。第二表面4412面向柔性显示屏10。多个支撑条442嵌设于柔性基底441的第一表面4411。多个支撑条442并未延伸至第二表面4412。弯折支撑件4通过柔性基底441接触柔性显示屏10,柔性基底441能够在柔性显示屏10受到外力时,提供缓冲作用,从而保护柔性显示屏10。另一些实施例中,多个支撑条442能够被柔性基底441包裹,多个支撑条442与第一表面4411及第二表面4412之间均具有间距。另一些实施例中,多个支撑条442自第一表面4411延伸至第二表面4412。本申请不对支撑条442与柔性基底441的相对位置关系作严格限定。
一些实施例中,弯折支撑件4的其中一个或其中多个支撑条442正对第一支撑部12设置。第一支撑部12包括多个第一支撑块。在平行于转轴组件3的转动轴线31的方向上,相邻两个第一支撑块之间的间距可以小于、等于或者大于第一支撑块的长度。
一些实施例中,请一并参阅图15至图17,图15是图1所示电子设备100的折叠组件20在再一实施例中的结构示意图;图16是图1所示电子设备100在C1-C1线处的部分结构在再一实施例中的剖视图;图17是图2所示电子设备100在C2-C2线处的部分结构在再一实施例中的剖视图。图15至图17所示实施例彼此对应。其中,图1的C1-C1线所在平面与图2的C2-C2线所在平面为同一平面。图15的C3-C3线所在平面与图1的C1-C1线所在平面亦为同一平面。
本实施例与前述实施例不同的是,弯折支撑件4采用弹性金属材料。弹性金属材料包括但不限于弹簧钢。弯折支撑件4呈面状或者网格状。弯折支撑件4的第一侧部41滑动连 接第一主壳部11,第二侧部42滑动连接第二主壳部21。在本实施例中,弯折支撑件4能够为柔性显示屏10提供连续、平滑且强度较高的支撑,使得柔性显示屏10的观感及手感更佳。
示例性的,第一主壳部11具有第一滑槽111和第一限位槽112。第一限位槽112连通第一滑槽111。弯折支撑件4的第一侧部41滑动安装于第一滑槽111。第一侧部41具有凸起的第一限位块411。第一限位块411滑动安装于第一限位槽112。在第一壳体1相对第二壳体2转动的过程中,第一限位槽112对第一限位块411的滑动方向和位置进行引导和限定,使得第一侧部41顺利地相对第一滑槽111滑动,同时也避免第一侧部41意外脱离第一滑槽111,使得折叠组件20的可靠性较高。第一限位块411与第一限位槽112的配合结构可以为一组或者多组,本实施例以两组为例进行示意。
第二主壳部21具有第二滑槽211和第二限位槽212。第二限位槽212连通第二滑槽211。弯折支撑件4的第二侧部42滑动安装于第二滑槽211。第二侧部42具有凸起的第二限位块421。第二限位块421滑动安装于第二限位槽212。在第一壳体1相对第二壳体2转动的过程中,第二限位槽212对第二限位块421的滑动方向和位置进行引导和限定,使得第二侧部42顺利地相对第二滑槽211滑动,同时也避免第二侧部42意外脱离第一滑槽111,使得折叠组件20的可靠性较高。第二限位块421与第二限位槽212的配合结构可以为一组或者多组,本实施例以两组为例进行示意。
可以理解的是,当弯折支撑件4呈网格状时,网格密度和格线宽度依据折叠组件20的支撑强度需求进行设计,本申请对此不作严格限定。
可以理解的是,前述实施例中电子设备100的宽度方向X垂直于转轴组件3的转动轴线31,电子设备100可以为左右对折结构。其他一些实施例中,电子设备100的宽度方向也可以平行于转轴组件3的转动轴线31,电子设备100可以为上下对折结构。本申请对此不作严格限定。
可以理解的是,前述实施例以电子设备100是两折结构(也即能够进行一次折叠)为例进行说明。在其他一些实施例中,电子设备100也可以是三折结构(也即能够进行两次折叠),或者四折结构(也即能够进行三次折叠)等,电子设备100的具体结构设计参阅前述实施例。示例性的,电子设备100还包括第三平面区域,第三平面区域通过另一弯折区域连接第一平面区域1001或第二平面区域1003。
以上所述,仅为本申请的具体实施例,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内;在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。因此,本申请的保护范围应以所述权利要求的保护范围为准。
