Description

可拉伸显示面板及电子装置 技术领域
本发明涉及显示技术领域，尤其涉及一种可拉伸显示面板及电子装置。
 背景技术
柔性有机发光二极管（organiclightemittingdiode, OLED）显示技术日趋成熟，可折叠显示产品已进入商用化阶段，且随着相关技术的不断突破，在很大程度上推动了中小尺寸柔性显示面板往可拓展、可折叠的显示方向深入发展。为满足消费者对手机、平板、电视等显示设备实现宽屏、交互屏、拓展屏等使用需求，柔性宽屏显示已成为重点研究方向。柔性宽屏显示技术的难点主要集中在如何实现电子设备整机的便携性、轻薄化的结构设计。
 技术问题
现阶段，柔性显示电子装置的结构设计主要分为折叠式、卷曲式和拉伸式三种。其中，折叠式电子装置分为外折式和内折式。对于外折式电子装置，因其屏幕暴露于整机的外侧，极易受到外界的摩擦，在使用一段时间后容易出现划痕，对其外观影响较大。对于内折式电子装置，受其整机厚度尺寸的限制，屏幕的弯折半径往往设计的很小，通常在弯折一定次数后，屏幕的弯折区位置容易出现折痕现象。而内外双折式显示设备，整机结构在折叠状态下，厚度方向有三层结构，总体厚度尺寸必然占用空间较大，导致便携性较差，目前外观优化设计未见较优的解决方案。此外，卷曲式显示方式在一定程度上实现了柔性化和可拓展式显示，因受卷曲圈数、卷曲半径的限制，整机的传动机构、屏幕收藏结构的设计十分复杂，无法做到轻薄化设计的功能需求。拉伸时显示方式可以通过相对滑动地主机架和副机架实现可拉伸式拓展显示结构设计，但是副机架在收展的过程中，无法保持传动的顺滑和平稳，并且当所施加的外力过大或突变时，副机架可能会与主机架分离，导致对机架和显示面板造成损坏。
综上所述，现有可拉伸显示面板及电子装置存在机架在收展过程中无法保持传动的顺滑和平稳导致对机架和显示面板造成损坏的问题。故，有必要提供一种可拉伸显示面板及电子装置来改善这一缺陷。

通过联动保持机构4的圆周滑动运动提升副机架30相对于主机架20滑动的顺滑和平稳性，并利用联动保持机构4对副机架30施加的拉力以及摩擦力，限制副机架30相对于主机架20的滑动速度和滑动距离，避免当施加的外力过大或突变时副机架30与主机架20分离，从而降低对机架2和柔性显示面板主体1造成损坏的风险。
结合图1至图3、以及图6所示，图1为本申请实施例提供的可拉伸柔性显示面板处于完全收藏状态的示意图，图2为本申请实施例提供的可拉伸柔性显示面板处于单边展开状态的示意图，图3为本申请实施例提供的可拉伸柔性显示面板处于双边展开状态的示意图，图6为本申请实施例提供的机架展开运动的原理示意图。
在本申请实施例中，所述副机架30包括两个副机架，分别为第一副机架31和第二副机架32，所述第一副机架31可滑动地连接于所述主机架20，第二副机架32与所述第一副机架31相对设置，并可滑动地连接于所述主机架20，第一副机架31和第二副机架32均可以相对于主机架20滑动。

在实际应用中，所述可拉伸显示面板100也可以仅具有一个副机架30和1个联动保持机构4。如图1和图2所示，当可拉伸显示面板100仅有一个副机架30时，可拉伸显示面板100可以具有如图1所示的收藏状态和图2所示的单边展开状态，利用联动保持机构4同样也提高副机架30滑动的顺滑和平稳性，并降低机架2和柔性显示面板主体1造成损坏的风险。
结合图1和图4所示，图4为本申请实施例提供的机架处于完全收藏状态的示意图，当可拉伸显示面板100处于完全收藏状态，第一副机架31和第二副机架32均靠近主机架20并至少部分可以收容于主机架20中，主体部10暴露于机架2的外侧，用于实现画面显示的功能。第一柔性部12和第二柔性部13的至少部分可以收容于机架2内的容置空间，以此减小可拉伸显示面板100和电子装置的尺寸，从而提高电子装置的便携性，并且能够避免第一柔性部12和第二柔性部13造成磨损、划伤。
当可拉伸显示面板100处于如图2所示的单边展开状态，用户可以通过拉伸第一副机架31，使第一副机架31沿箭头所示的第一方向x相对于主机架20滑动并远离主机架20，同时将第一柔性部12的至少部分暴露于机架2的外侧。第一柔性部12的至少部分可以与主体部10处于同一平面，并且可以与主体部10共同实现画面显示的功能。第二副机架32靠近主机架20，并保持收藏状态，第二柔性部13可以收容于机架2内的容置空间。在实际应用中，也可以将第二柔性部13暴露于机架2的外侧，将第一柔性部12收容于机架2内的容置空间。
在实际应用中，用户可以根据实际需求，选择将第一柔性部12和第二柔性部13中的一个展开，将第一柔性部12和第二柔性部13中的另一个收容于机架2内的容置空间，以此获得大于或等于如图1所示的收藏状态下1.8倍的显示面积。
结合图3和图5所示，图5为机架处于双边展开状态的示意图，当可拉伸显示面板100处于双边展开状态，用户可以通过拉伸第一副机架31和第二副机架32，使第一副机架31和第二副机架32分别沿第一方向x和与第一方向x相反的方向相对于主机架20滑动并远离主机架20，同时将第一柔性部12和第二柔性部13的至少部分暴露于机架2的外侧。第一柔性部12和第二柔性部13的至少部分可以与主体部10处于同一平面，并且可以与主体部10共同实现画面显示的功能，以此获得大于或等于如图1所示的收藏状态下2.8倍的显示面积。

在一实施例中，如图6所示，联动保持机构4包括第一联动保持机构4a和第二联动保持机构4b，第一联动保持机构4a和第二联动保持机构4b的结构相同，并且均包括第一连杆41和第二连杆42。
以图6中第一联动保持机构4a和第一副机架31为例进行说明，第一连杆41的第一端411可转动地连接于主机架20，第一连杆41的第二端412可滑动地连接于第一副机架31。第二连杆42的第一端421可转动地连接于主机架20，第二连杆42的第二端422可滑动地连接于第一副机架31。
具体的，第一副机架31具有第一支撑板310，第一支撑板310用于在展平状态或收藏状态时，支撑主体部10和第一柔性部12。第一支撑板310背离主机架20的一端设有第一滑槽311和第二滑槽312，第一滑槽311和第二滑槽312均具有两个端点，分别为第一限位点A和第二限位点B，第一连杆41的第二端412可在第一滑槽311的第一限位点A至第二限位点B之间进行滑动，第二连杆42的第二端422可以在第二滑槽312的第一限位点A至第二限位点B之间进行滑动。
如图7和图8所示，图7为本申请实施例提供的主机架的结构示意图，图8为本申请实施例提供的第一种主机架沿A-A方向的剖视图，主机架20具有主支撑板21、主底板22以及位于主支撑板21的相对端并连接所述主支撑板21和主底板22的第一连接板23和第二连接板24。主支撑板21靠近主底板22的一侧设有相对设置的第一销钉座211和第二销钉座212。
结合图6至图8所示，第一联动保持机构4a还包括第一固定件43、第二固定件44、第三固定件45和第四固定件46，第一固定件43、第二固定件44、第三固定件45和第四固定件46均可以为销钉。
第一连杆41的第一端411通过第三固定件45可转动地连接于第一销钉座211，第一固定件43穿过第一滑槽311并固定连接于第一连杆41的第二端412，第一固定件43和第一连杆41的第二端412，可以相对于第一滑槽311滑动并转动。第二连杆42的第一端421通过第四固定件46可转动地连接于第二销钉座212，第二固定件44穿过第二滑槽312并固定连接于第二连杆42的第二端422，第二固定件44和第二连杆42的第二端422可以相对于第二滑槽312滑动并转动。
如图6所示，当机架2处于完全收藏状态，柔性部11处于第一状态，第一状态指的是柔性部11至少部分收容于机架2内的容置空间的状态。第一连杆41的第二端412和第一固定件43均处于第一滑槽311的第二限位点B，第二连杆42的第二端422和第二固定件44均处于第二滑槽312的第二限位点B，第一固定件43和第二固定件44彼此相互靠近。
在第一副机架31由收藏状态展开至展开状态的过程中，第一连杆41的第一端411绕第三固定件45旋转，第一连杆41的第二端412和第一固定件43在第一滑槽311内沿第二方向y由第二限位点B逐渐向第一限位点A滑动。当机架2展开至双边展开状态时，第一连杆41的第二端412和第一固定件43均处于第一滑槽311的第一限位点A。
第二连杆42的第一端421绕第四固定件46旋转，第二连杆42的第二端422和第二固定件44在第二滑槽312内沿与第二方向y相反的方向由第二限位点B逐渐向第一限位点A滑动，并与第一固定件43相互远离。
当第一副机架31处于展开状态时，第二连杆42的第二端422和第二固定件44均处于第二滑槽312的第一限位点A。此时，柔性部11处于第二状态，第二状态指的是柔性部11暴露于机架2的外侧，且至少部分与主体部10处于同一平面。
在第一副机架31由收藏状态展开至展开状态的过程中，第一连杆41绕第三固定件45沿箭头所示的方向，在第一限位点A和第二限位点B的区间进行圆周滑动运动，并向第一副机架31施加与第一方向x相反的拉力以及与第二方向y相反的摩擦力，第二连杆42绕第四固定件46沿箭头所示的方向，在第一限位点A和第二限位点B进行圆周滑动运动，并向第一副机架31施加与第一方向x相反的拉力以及与平行于第二方向y的摩擦力。利用第一限位点A和第二限位点B对第一副机架31的滑动进行卡位，以此限制第一副机架31的滑动速度和滑动距离，避免施加的外力过大或突变时第一副机架31与主机架20分离，从而降低对机架2和柔性显示面板主体1造成损坏的风险，同时还可以利用第一连杆41和第二连杆42的相向或相背的圆周滑动运动，使得第一副机架31的两端保持同步运动，从而提高第一副机架31滑动的顺滑和平稳性。
需要说明的是，在机架2由完全收藏状态展开至双边展开状态的过程中，第二副机架32和第二联动保持机构4b的结构以及运动过程与第一副机架31和第一联动保持机构4a的运动过程相似，且具有相同的有益效果，具体可参考第一副机架31和第一联动保持机构4a的结构以及运动过程，此处不再赘述。
此外，第一联动保持机构4a和第二联动保持机构4b还可以起到对第一副机架31和第二副机架32的支撑作用，避免第一副机架31的第一支撑板310和第二副机架32的第二支撑板320在收到第三方向z的压力时发生塌陷。
在一实施例中，如图6所示，所述第一滑槽311和所述第二滑槽312均为直线槽，且所述第一滑槽311和第二滑槽312的长度方向均平行于第二方向y。
在一实施例中，当所述第一滑槽311为直线槽，所述第一滑槽311的长度方向倾斜于第二反向y，并且与第二方向y之间呈一定的夹角，第二滑槽312与第一滑槽311对称设置，且大小、形状相同。该夹角可以包括但不限于3°、5°、7°等，使得第一连杆41的长度方向与第一滑槽311的长度方向之间的夹角始终大于90°，第二连杆42的长度方向与第二滑槽312的长度方向之间的夹角也始终大于90°，如此可以减小第一连杆41的第二端412和第二连杆42的第二端422由第一限位点A开始向第二限位点B运动时所需要克服的摩擦力，从而可以使第一副机架31更加顺滑的由展开状态收缩至收藏状态。
在一实施例中，所述第一滑槽311的中间段为直线槽，第一滑槽311的两端为弧形槽，第二滑槽312与第一滑槽311对称设置，且大小、形状相同，如此同样可以减小第一连杆41的第二端412和第二连杆42的第二端422由第一限位点A开始向第二限位点B运动时所需要克服的摩擦力。

在机架2收展的过程中，第一支撑条313可相对于第三滑槽213平行滑动，第二支撑条323可相对于第四滑槽214平行滑动，以此提高第一副机架31和第二副机架32在收展过程中的顺滑性。同时，第三滑槽213和第四滑槽214之间还设有凸起215，所述凸起215与所述第一支撑条313和所述第二支撑条323处于同一平面，以此利用所述凸起215和所述第一支撑条313以及所述第二支撑条323对柔性显示面板主体1进行支撑，提高柔性显示面板主体1在收藏状态和展开状态下的平整性。
具体的，柔性显示面板主体1的主体部10可以采用易拉胶或点胶的方式与主机架20的主支撑板21贴合固定，易拉胶可以设置于主支撑板21上的多个凸起215上。
进一步的，所述副机架30远离所述主机架20的一端呈弧形。

第二副机架32的第二支撑板320还包括第三支撑部324和第四支撑部325，第三支撑部324的一端连接于多个第二支撑条323，第三支撑部324的另一端连接于第四支撑部325，第四支撑部325设置于第三支撑部324远离主机架20的一端。第三支撑部324为平面支撑部，第四支撑部325呈弧形，可以用于支撑第二柔性部13，以使第二柔性部13对应第四支撑部325的部分呈曲面。第二副机架32还包括第二保护盖板326，第二保护盖板326固定连接于第三支撑部324和第四支撑部325的外侧，以此保护由第二支撑板320表面绕过第三支撑部324和第四支撑部325的第二柔性部13。
当电子装置处于完全收藏状态、单边展开状态或双边展开状态时，第一柔性部12和第二柔性部13的至少部分可以位于第一副机架31或第二副机架的第二支撑部315支撑部上，以此使得位于第二支撑部315上的第一柔性部12和第二柔性部13均呈曲面，从而实现电子装置在不同状态下都可以保持左右双侧边缘曲面显示的效果。
进一步的，所述可拉伸显示面板100包括收卷机构，所述收卷机构安装于所述机架内。
如图13和图14所示，图13为本申请实施例提供的柔性显示面板主体的结构示意图，图14为本申请实施例提供的可拉伸显示面板处于完全收藏状态的装配示意图。

具体的，第一收卷机构51包括第一弹性件510，第一弹性件510的一端固定连接于主机架20，第一弹性件510的另一端固定连接于第一柔性部12。当第一柔性部12处于第一状态时，第一柔性部12收容于机架2内的容置空间，第一弹性件510处于弹性变形状态，第一弹性件510被拉伸，以此通过第一弹性件510对第一柔性部12施加一定的预紧力，使第一柔性部12处于拉伸状态，保证第一柔性部12在机架内的平整性，并防止第一柔性部12在机架2内发生晃动。
当第一柔性部12处于第二状态时，第一柔性部12暴露于机架2的外侧，第一弹性件510也处于弹性变形状态，且弹性形变量增大，以此通过第一弹性件510对第一柔性部施加预紧力，保证第一柔性部12在显示画面时平整性。当第一柔性部12需要从第二状态恢复至第一状态时，第一弹性件510还可以向第一柔性部12施加收藏拉力，以使第一柔性部12可以收容至机架2内。第二弹性件520的工作原理以及效果与第一弹性件510的相同，具体可参考第一弹性件510，此处不再赘述。

下面以第一副机架31侧的结构为例进行说明。当对第一柔性部12进行展开时，第一副机架31沿第一方向x滑动，第一柔性部12相对于第一齿轮610沿可第三方向z运动，在第一齿轮610与齿轮辐条的啮合作用下，带动第一齿轮610沿逆时针方向运动。当第一柔性部12处于展开状态时，第一履带式支撑板121随同第一柔性部12一同展开，第一履带式支撑板121在展开时具有一定的支撑刚度，可用于支撑第一柔性部12，避免第一柔性部12在展开时发生皱褶、折痕或塌陷，从而可以提高柔性显示面板主体1的平整性。
当对第一柔性部12进行收藏时，第一副机架31沿与第一方向x相反的方向滑动，第一柔性部12在第一收卷机构51的收藏拉力作用下相对于第一齿轮610沿与第三方向z相反的方向运动，在第一齿轮610与齿轮辐条的啮合作用下，带动第一齿轮610沿顺时针方向运动。
