在本申请实施例中,在所述折叠显示装置100由展开状态至完全弯折状态的过程中,所述第一转动板132的第一端至所述第一弧形凸起部1341的间距逐渐增大,所述第二转动板133的第一端至所述第二弧形凸起部1331的间距逐渐增大。
具体地,所述折叠显示装置100的转动原理过程如下:
所述第一壳体11、所述第二壳体12与弯折部131为轴连接,所述第一壳体11、所述第二壳体12分别可围绕各自轴心相对弯折部131进行旋转;所述第一转动板132或所述第二转动板133的一端与所述弯折部131亦为轴连接,即转动板围绕轴心相对弯折部131旋转;所述第一转动板132或所述第二转动板133的另一端与对应的所述第一支撑板134或者所述第二支撑板135为直线滑槽连接,从而使所述第一支撑板134或者所述第二支撑板135可相对所述第一转动板132或所述第二转动板133进行直线滑动;同时所述第一支撑板134或者所述第二支撑板135的另一端与所述第一壳体11或所述第二壳体12为圆弧形滑槽连接,圆弧形滑槽的圆心即为所述第一支撑板134或者所述第二支撑板135与所述第一壳体11、所述第二壳体12之间的旋转中心,即所述第一支撑板134或者所述第二支撑板135可围绕该旋转中心相对所述第一壳体11或所述第二壳体12进行旋转。当所述第一壳体11或者所述第二壳体12与所述弯折部131围绕其各自旋转中心旋转时,所述第一转动板132或所述第二转动 板133亦围绕其与所述弯折部131之间的旋转中心进行旋转,同时所述第一支撑板134或者所述第二支撑板135围绕其与所述第一壳体11或所述第二壳体12之间的旋转中心同步旋转,由于所述第一支撑板134或者所述第二支撑板135与所述第一转动板132或所述第二转动板133之间为直线滑槽连接,因此所述第一支撑板134或者所述第二支撑板135与所述第一壳体11或者所述第二壳体12之间的夹角始终与所述第一转动板132或所述第二转动板133与所述第一壳体11或者所述第二壳体12之间的夹角相等,而所述第一转动板132或所述第二转动板133与所述第一壳体11、所述第二壳体12相对所述弯折部131的旋转中心位置不一致导致,在所述第一壳体11与所述第二壳体12相对所述弯折部131转动时,所述第一转动板132或所述第二转动板133与所述弯折部131之间的转动角度与所述第一壳体11、所述第二壳体12相对所述弯折部131之间的转动角度不同,导致所述第一支撑板134或者所述第二支撑板135相对所述第一壳体11或者所述第二壳体12会倾斜一定角度,倾斜的角度由所述第一转动板132或所述第二转动板133与所述弯折部131之间的旋转中心位置、所述第一壳体11/所述第二壳体12与所述弯折部131之间旋转中心的位置、所述第一支撑板134或者所述第二支撑板135与所述第一壳体11/所述第二壳体12之间旋转中心的位置共同决定。因此在所述第一壳体11/所述第二壳体12相对所述弯折部131进行转动时,位于弯折区的所述第一支撑板134或者所述第二支撑板135会向下倾斜为所述柔性显示面板20让出弯折空间,在完全弯折后,所述第一支撑板134或者所述第二支撑板135张开成楔形,使弯折区的所述柔性显示面板20形成类水滴形状。
如图4A所示,为本申请实施例折叠显示装置100在展开状态时的平面示意图;如图4B所示,为本申请实施例折叠显示装置100在展开状态时的截面示意图;其中,根据图4A以及图4B可知,所述联动滑块14包括:
滑块主体141,呈水平设于所述弯折部131的纵向对称轴位置,与所述弯折部131在所述弯折部131的纵向对称轴位置可滑动连接;
圆柱滑块142,呈水平设于所述滑块主体141的两端,所述圆柱滑块142与所述第一壳体11或所述第二壳体12内侧的第一滑槽可滑动连接;
矩形滑块143,位于所述滑块主体141上且呈竖直设于所述弯折部131的 纵向对称轴位置,所述矩形滑块143与所述弯折部131内侧的第二滑槽1311可滑动连接;
在本申请实施例中,所述第一滑槽包括设置于所述第一壳体11上的第一子滑槽111以及设置于所述第二壳体12上的第二子滑槽121,所述第一子滑槽111与所述第二子滑槽121以所述第二滑槽1311为对称轴对称设置。
进一步地,所述折叠显示装置100处于展平状态时,所述第一子滑槽111或所述第二子滑槽121与所述第二滑槽1311的夹角为45°;所述圆柱滑块142与所述弯折部131的底端处于同一水平面。
如图5A所示,为本申请实施例折叠显示装置100在内弯折90°状态时的侧面示意图;如图5B所示,为本申请实施例折叠显示装置100在内弯折90°状态时的截面示意图;
其中,在所述折叠显示装置100处于内弯折90°状态时,设定所述矩形滑块143的高度为h,所述滑块主体141的长度为L,此时,所述第一子滑槽111或所述第二子滑槽121与所述第二滑槽1311的夹角为arctan(2h/L)。
如图6A所示,为本申请实施例折叠显示装置100在完全弯折状态时的侧面示意图;如图6B所示,为本申请实施例折叠显示装置100在完全弯折状态时的截面示意图;
其中,在所述折叠显示装置100处于完全弯折状态时,所述矩形滑块143的顶端与所述弯折部131的顶端处于同一水平面,所述第一子滑槽111或所述第二子滑槽121与所述第二滑槽1311的夹角为135°。
具体地,在所述折叠显示装置100由展开状态弯折至内弯折90°状态,最终处于完全弯折状态的过程中,由于所述第一壳体11、所述第二壳体12内侧设有滑槽,与所述滑块主体141上的所述圆柱滑块142配合,所述滑块主体141中部设有所述矩形滑块143与所述弯折部131上的直线滑槽配合,当所述第一壳体11相对所述弯折部131旋转时,所述第一壳体11内壁的所述第一子滑槽111带动所述滑块主体141上的所述圆柱滑块142向上运动,由于所述滑块主体141上的所述矩形滑块143被所述弯折部131上的所述第二滑槽1311限制只能上下平移,因此所述滑块主体141被带动向上平移,从而使得所述滑块主体141通过所述圆柱滑块142与所述第二壳体12内壁的第二子滑槽121 的配合,推动所述第二壳体12旋转与所述第一壳体11相等且方向相反的角度,实现所述第一壳体11与所述第二壳体12在折叠运动过程中始终保持位置对称。
本申请实施例提供一种折叠显示装置100,包括弯折部131、第一转动板132、第一转动板132、第一壳体11、第二壳体12、第一支撑板134、第二支撑板135以及一联动滑块14;
其中,所述弯折部131呈水平设置,其横截面为沿纵向对称轴镜像设置的轴对称结构;所述第一转动板132设于所述弯折部131的纵向对称轴的第一侧,所述第一转动板132的第一端与所述弯折部131为轴连接;所述第二转动板133设于所述弯折部131的纵向对称轴相反于所述第一侧的第二侧,且与所述第一转动板132相对于所述纵向对称轴镜像设置,所述第二转动板133的第一端与所述弯折部131为轴连接;所述第一壳体11设于所述弯折部131的纵向对称轴的第一侧,所述第一壳体11与所述弯折部131为轴连接;所述第二壳体12设于所述弯折部131的纵向对称轴相反于所述第一侧的第二侧,所述第二壳体12与所述弯折部131为轴连接;所述第一支撑板134设于所述第一转动板132以及所述弯折部131上,所述第一支撑板134的第一端与所述第一转动板132的第二端为第一滑动连接,所述第一支撑板134的第二端与所述第一壳体11为第二滑动连接;所述第二支撑板135设于所述第二转动板133以及所述弯折部131上,且与所述第一支撑板134相对于所述纵向对称轴镜像设置,所述第二支撑板135的第一端与所述第二转动板133的第二端为所述第一滑动连接,所述第二支撑板135的第二端与所述第二壳体12为所述第二滑动连接;所述至少一联动滑块14设于所述弯折部131的纵向对称轴位置,且分别与所述第一壳体11以及所述第二壳体12为第三滑动连接;
其中,当所述联动滑块14与所述弯折部131的底端处于同一水平面时,所述第一壳体11与所述第二壳体12展开在同一平面,所述折叠显示装置100处于第一状态;当所述联动滑块14与所述弯折部131的顶端处于同一水平面时,所述第一壳体11与所述第二壳体12对折重合,所述折叠显示装置100处于第二状态。
本申请实施例提供的折叠显示装置100及显示装置,通过在折叠显示装置 100的弯折部131的纵向对称轴的两侧设置转动板,使折叠显示装置100在弯折时,位于弯折区的支撑板倾斜为显示屏让出空间,形成泪水滴形状,同时,通过联动滑块14实现弯折部131两侧机壳在旋转过程中联动,代替了传统的齿轮联动设计,从而在折叠显示装置100处于展平状态时使得弯折区的支撑板恢复平整,对弯折区的显示屏提供整面支撑,且使折叠显示装置100在弯折过程中始终保持对称状态,进一步减少折叠显示装置100对显示屏的损伤。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
