本申请主张在2019年10月21日在中国提交的中国专利申请号No.201911002018.4的优先权，其全部内容通过引用包含于此。
技术领域
本申请涉及通信技术领域，特别是涉及一种盖板、一种显示模组以及一种折叠式电子设备。
背景技术
随着对于使用体验的极致追求，用户对于智能手机、平板电脑等电子设备的性能要求也越来越高。折叠式电子设备作为一种新型的电子设备，其在展开状态下时，屏幕较大，可以使得用户获得较好的视频观赏效果，实现较好的应用操作体验；其在折叠状态下时，体积较小，可以方便用户携带。因此，折叠式电子设备已逐渐成为一种发展的趋势。
由于折叠式电子设备的屏幕需要反复弯折，因此，屏幕上的盖板也需要反复弯折。在盖板弯折的过程中，盖板上的弯折处很容易产生较大的内应力，在该内应力的作用下，盖板表面很容易出现凹凸不平的现象。
发明内容
有鉴于此，为了解决现有的折叠式电子设备中，盖板的弯折处容易出现表面凹凸不平的问题，本申请实施例提供了一种盖板、一种显示模组以及一种折叠式电子设备。
第一方面，本申请实施例公开了一种用于折叠式电子设备的盖板，包括：透光的第一子盖板、透光的第二子盖板以及透光的弯折部；
所述弯折部连接在所述第一子盖板和所述第二子盖板之间，所述弯折部上设置有多个开孔，所述开孔内填充有透光的填充件；所述第一子盖板、所述第二子盖板通过所述弯折部的弯折可折叠，其中，所述填充件的韧性大于所述第一子盖板和所述第二子盖板的韧性。
第二方面，本申请实施例还公开了一种显示模组，包括：柔性屏幕和上述 盖板；其中，
所述柔性屏幕包括第一柔性子屏幕和第二柔性子屏幕；
所述第一柔性子屏幕和所述第二柔性子屏幕可相对折叠；
所述盖板的第一子盖板与所述第一柔性子屏幕连接，所述盖板的第二子盖板与所述第二柔性子屏幕连接。
第三方面，本申请实施例还公开了一种折叠式电子设备，包括：上述显示模组。
本申请实施例包括以下优点：
本申请实施例中，盖板的弯折部连接在第一子盖板和第二子盖板之间，所述弯折部上设置有多个开孔，所述开孔内填充有透光的填充件，所述填充件的韧性大于所述第一子盖板和所述第二子盖板的韧性。这样，在所述第一子盖板、所述第二子盖板通过所述弯折部的弯折进行折叠时，所述弯折部上的开孔、以及所述开孔内的填充件可以用于释放所述弯折部的折弯应力，保持所述第一子盖板和所述第二子盖板的平整，避免所述盖板出现凹凸不平的现象，提高所述盖板的折弯性能。
附图说明
图1是本申请的一种盖板处于展开状态的结构示意图；
图2是本申请的一种盖板处于折叠状态的结构示意图；
图3是本申请的一种显示模组的结构示意图。
具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请作进一步详细的说明。
参照图1，示出了本申请的一种盖板处于展开状态的结构示意图，参照图2，示出了本申请的一种盖板处于折叠状态的结构示意图，具体可以包括：透光的第一子盖板10、透光的第二子盖板11以及透光的弯折部12；弯折部12连接在第一子盖板10和第二子盖板11之间，弯折部12上设置有多个开孔121，开孔121内填充有透光的填充件；第一子盖板10、第二子盖板11通过弯折部12的弯折可折叠，其中，所述填充件的韧性大于第一子盖板10和第二子盖板11的 韧性。
本申请实施例中，在第一子盖板10、第二子盖板11通过弯折部12的弯折进行相对折叠时，由于弯折部12上设置有多个开孔121，开孔121内填充有透光的填充件，所述填充件的韧性大于第一子盖板10和第二子盖板11的韧性，开孔121以及开孔121内的所述填充件可以用于释放弯折部12的折弯应力，提高弯折部12的折弯性能，使得所述盖板可以反复多次被折叠，提高所述盖板的使用寿命。
而且，由于通孔121可以用于释放弯折部12的折弯应力，这样，可以使得所述盖板在折叠时还可以保持第一子盖板10和第二子盖板11的平整，避免所述盖板出现凹凸不平的现象。
在实际应用中，在所述盖板应用于电子设备的情况下，在第一子盖板10、第二子盖板11通过弯折部12的弯折进行相对折叠时，弯折部12上的开孔121可以通过变形来释放弯折部12的折弯应力，而且，由于开孔121内的填充件的韧性大于第一子盖板10和第二子盖板11的韧性，开孔121内的填充件可以进一步减小弯折部12的折弯应力，提高弯折部12的折弯性能，避免由于弯折部12上的折弯应力无法释放时导致第一子盖板10和第二子盖板11容易拱起的问题，保持第一子盖板10和第二子盖板11的平整。
本申请实施例中，弯折部12的开孔121内可以填充有透光的填充件，这样，在所述盖板处于图1所示的展开状态或者图2所示的折叠状态时，由于开孔121内填充有透光的填充件，可以使得开孔121与周边区域保持外观一致性，提高所述盖板的外观效果。
在实际应用中，在所述盖板应用于电子设备上时，由于开孔121可以用于释放弯折部12的折弯应力，保持第一子盖板10和第二子盖板11的平整，因此，第一子盖板10、第二子盖板11的厚度可以设计得较厚。这样，就可以避免第一子盖板10和第二子盖板11较薄时电子设备的屏幕表面容易出现的凹凸不平的现象，使得所述盖板不容易出现被刮花的现象，提高所述盖板的耐刮性能，而且，可以进一步提高所述电子设备的外观效果。
在本申请的一种可选实施例中，多个开孔121在弯折部12上可以均匀分布。 在实际应用中，在多个开孔121均匀分布的情况下，可以使得开孔121可以均匀的释放弯折部12的折弯应力，进一步提高弯折部12在弯折时的折弯应力释放效果，进而，可以进一步提高弯折部12的折弯性能，提高所述盖板的使用寿命。
当然，在实际应用中，本领域技术人员也可以根据实际需要设计通开孔121在弯折部12上的具体分布情况。例如，在折弯应力较大的区域可以设置数量较多的开孔121，而在折弯应力较小的地方则可以设置数量较少的开孔121。本申请实施例对于开孔121在弯折部12上的具体分布可以不做限定。
本申请实施例中，开孔121的尺寸满足预设范围，以使得开孔121可以兼顾较好的折弯应力释放效果和较好的加工性能。具体地，开孔121的尺寸可以为开孔121的长度、宽度或者直径等尺寸。例如，在开孔121形状为圆形的情况下，开孔121的尺寸可以为直径。又如，在开孔121的形状为椭圆形的情况下，开孔121的尺寸可以为长度和宽度。本申请实施例对于开孔121的尺寸的具体内容可以不做限定。
具体地，所述预设范围可以为0.01～0.10毫米。具体地，在开孔121的尺寸为0.01～0.10毫米的情况下，开孔121可以具有较好的折弯应力释放效果，并且，从所述盖板的外观上很难看出开孔121的边界，可以使得所述盖板的外观效果较好。而且，在开孔121的尺寸为0.01～0.10毫米的情况下，采用通用的激光打孔机或者激光微孔器即可加工开孔121，使得开孔121的加工性能较好。
本申请实施例中，开孔121的具体尺寸可以根据实际情况进行设定。例如，在所述盖板的厚度较厚的情况下，由于所述盖板的折弯应力较大，相应的，开孔121的尺寸可以相应较大。又如，在所述盖板的折弯半径较大的情况下，为了提高开孔121对于折弯应力的释放效果，开孔121的尺寸可以相应较大。
可以理解的是，在实际应用中，本领域技术人员可以根据实际需要设置开孔121的具体尺寸。例如，将开孔121设置成大于0.01毫米且小于0.1毫米的尺寸皆可。本申请实施例对于开孔121的具体尺寸可以不做限定。
可选地，开孔121可以为通孔或者盲孔，本申请实施例对于开孔121的具体类型可以不做限定。
本申请实施例中，开孔121内的填充件的反射率与弯折部12的反射率可以一致，以进一步提高通孔121与周边区域的外观一致性。
具体地，所述填充件可以采用光学胶或者其他韧性较大的透明材料制成。所述填充件可以为光学胶填充件，所述光学胶填充件采用有机硅胶、丙烯酸型树脂、不饱和聚酯、聚氨酯、环氧树脂等光学胶制成。由于光学胶具有无色透明、光透过率在90％以上、胶结强度良好，可在室温或中温下固化，且有固化收缩小等特点。在采用光学胶制成所述光学胶填充件的情况下，不仅可以使得所述填充件能够透光，而且，还可以使得所述填充件具有较好的韧性，这样，当所述填充件填充于弯折部12的开口121内时，可以提高弯折部12的韧性，在一定程度上降低弯折部12的折弯应力。
在实际应用中，在开口121内的填充件的反射率与弯折部12的反射率一致的情况下，无论所述盖板处于图1所示的展开状态或者是图2所示的折叠状态，由于开口121内的填充件的反射率与弯折部12的反射率一致，开口121都可以保持与周边区域的外观一致性，这样，就可以进一步提升所述盖板的外观效果。
本申请实施例中，第一子盖板10、第一子盖板11为可以透光的盖板。具体地，在第一子盖板10、第一子盖板11为透光盖板的情况下，可以使得所述电子设备的屏幕发出的光线可以透过第一子盖板10、第二子盖板11，提高所述电子设备的显示效果。
可选地，第一子盖板10、第二子盖板11可以为玻璃盖板或者聚甲基丙烯酸甲酯盖板。在实际应用中，在第一子盖板10、第二子盖板11为玻璃子盖板的情况下，可以使得所第一子盖板10、第二子盖板11具有较优的透光性能、较优的耐刮性能以及较好的外观性能。在第一子盖板10、第二子盖板11为甲基丙烯酸甲酯盖板的情况下，则可以使得第一子盖板10、第二子盖板11具有优良的耐候性以及较好的加工性能。
可以理解的是，在实际应用中，本领域技术人员还可以根据实际需要选择其他透明的材料制成第一子盖板10和第二子盖板11，本申请实施例对于第一子盖板10、第二子盖板11的材质可以不做具体限定。
在本申请的一种可选实施例中，第一子盖板10、第二子盖板11以及弯折部 12可以为一体成型结构。在实际应用中，第一子盖板10、第二子盖板11以及弯折部12可以采用热压成型或者注塑成型等成型方式加工成一体成型结构，然后再采用激光加工的方式在弯折部12上加工开口121即可。
在实际应用中，在第一子盖板10、第二子盖板11以及弯折部12为一体成型结构的情况下，不仅可以简化所述盖板的加工工艺，还可以提高第一子盖板10、第二子盖板11以及弯折部12之间连接可靠性，进而，可以提高所述盖板的结构稳定性。
综上，本申请实施例所述的盖板至少包括以下优点：
本申请实施例中，盖板的弯折部连接在第一子盖板和第二子盖板之间，所述弯折部上设置有多个开孔，所述开孔内填充有透光的填充件，所述填充件的韧性大于所述第一子盖板和所述第二子盖板的韧性。这样，在所述第一子盖板、所述第二子盖板通过所述弯折部的弯折进行折叠时，所述弯折部上的开孔、以及所述开孔内的填充件可以用于释放所述弯折部的折弯应力，保持所述第一子盖板和所述第二子盖板的平整，避免所述盖板出现凹凸不平的现象，提高所述盖板的折弯性能。
参照图3，示出了本申请的一种显示模组的结构示意图，所述显示模组具体可以包括：柔性屏幕30和上述盖板31；其中，柔性屏幕30包括第一柔性子屏幕和第二柔性子屏幕；所述第一柔性子屏幕和所述第二柔性子屏幕可相对折叠；盖板31的第一子盖板与所述第一柔性子屏幕连接，盖板31的第二子盖板与所述第二柔性子屏幕连接。
本申请实施例中，由于所述第一子盖板与所述第一柔性子屏幕连接，所述第二子盖板与所述第二柔性子屏幕连接，在所述第一柔性子屏幕和所述第二柔性子屏幕相对折叠的过程中，所述第一子盖板、所述第二子盖板可以通过弯折部的弯折相应进行相对折叠。由于所述弯折部连接在第一子盖板和第二子盖板之间，所述弯折部上设置有多个开孔，所述开孔内填充有透光的填充件，所述填充件的韧性大于所述第一子盖板和所述第二子盖板的韧性。这样，在所述第一子盖板、所述第二子盖板通过所述弯折部的弯折进行折叠时，所述弯折部上的开孔、以及所述开孔内的填充件可以用于释放所述弯折部的折弯应力，保持 所述第一子盖板和所述第二子盖板的平整，避免所述盖板出现凹凸不平的现象，提高所述盖板的折弯性能。
综上，本申请实施例所述的显示模组至少包括以下优点：
