请参照图1和图2,本申请提供的电子设备100可以是折叠式手机、折叠式平板、折叠式电脑、折叠式穿戴设备、折叠式车载设备等。本申请实施例中以折叠式手机为例。电子设备100具有折合状态、展平状态。当然,电子设备100还可以具有处于折合状态与展平状态之间的一个或多个中间悬停状态。其中,图1为本申请实施例提供的电子设备100处于展平状态时的结构示意图。图2为本申请实施例提供的电子设备100处于折合状态时的结构示意图。电子设备100包括柔性显示屏2和折叠壳体1。本申请实施例提供的电子设备100为内折式电子设备,即柔性显示屏2设于折叠壳体1的内侧。内折式电子设备100可有效降低柔性显示屏2的撞击、延长柔性显示屏2的使用寿命。需要说明的是,本申请提供的主要发明构思也相应地适用于外折式电子设备。电子设备100处于展平状态时对应柔性显示屏2、折叠壳体1处于展平状态,此时,柔性显示屏2在折叠壳体1的作用下展平,有利于实现大屏幕显示。电子设备100处于折合状态时对应柔性显示屏2、折叠壳体1处于折合状态,此时,电子设备100的体积较小,方便携带。电子设备100处于中间悬停状态时对应柔性显示屏2、折叠壳体1处于中间悬停状态。本申请提供的电子设备100因具有以下实施例所描述的折叠壳体1,因此柔性显示屏2在反复折叠的过程中尺寸可基本保持不变,柔性显示屏2的折痕较浅,使用寿命较长。
请参照图2和图3,其中,图3为本申请实施例提供的电子设备100中柔性显示屏2与折叠壳体1的分解示意图。折叠壳体1包括第一壳体11、第二壳体12及转轴机构10。折叠壳体1处于展平状态时,第一壳体11与第二壳体12分别展平于转轴机构10的相对两侧,此时,第一壳体11与第二壳体12之间的夹角可以为180°(允许存在少许的偏差,例如:第一壳体11与第二壳体12之间的夹角还可以为175°、177°、179°、182°等)。折叠壳体1处于折合状态时,第一壳体11和第二壳体12位于转轴机构10的同一侧,并相对设置,第一壳体11、转轴机构10及第二壳体12之间形成用于容纳柔性显示屏2的第一容纳空间。其中,折叠壳体1在折合状态时所形成的第一容纳空间的形状可通过第一壳体11、第二壳体12及转轴机构10的具体结构设计实现,该部分内容在后续的实施例中具体说明。
柔性显示屏2用于显示画面。柔性显示屏2可以是有机发光二极管(Organic Light-Emitting Diode,OLED)显示屏、发光二极管(Light-Emitting Diode,OLED)显示屏等。柔性显示屏2覆盖于第一壳体11、转轴机构10及第二壳体12上,且柔性显示屏2的一端与第一壳体11固定连接,柔性显示屏2的另一端与第二壳体12固定连接。具体的,柔性显示屏2包括依次排列的第一非弯折区21、弯折区20及第二非弯折区22。第一非弯折区21覆盖于第一壳体11上,并与第一壳体11固定连接;第二非弯折区22盖于第二壳体12上,并与第二壳体12固定连接。可以理解的,第一非弯折区21随第一壳体11的展平而展平,第一非弯折区21随第一壳体11的折合而折合;第二非弯折区22随第二壳体12的展平而展平,第二非弯折区22随第二壳体12的折合而折合。其中,第一非弯折区21与第一壳体11的固定连接方式包括但不限于粘接;第二非弯折区22与第二壳体12的固定连接方式包括但不限于粘接。弯折区20覆盖于转轴机构10上。其中,弯折区20与转轴机构10未连接或未完全连接,便于至少部分弯折区20能够自由弯折。本申请中,柔性显示屏2的弯折区20与转轴机构10的具体连接关系在后续的实施例中进一步说明。柔性显示屏2处于展平状态时,第一非弯折区21、弯折区20及第二非弯折区22在折叠壳体1的作用下展平。柔性显示屏2处于折合状态时,第一非弯折区21、弯折区20及第二非弯折区22收容于折叠壳体1所形成的第一容纳空间内。
请参照图3至图7,其中,图4为本申请实施例提供的折叠壳体1处于展平状态的结构示意图;图5为本申请实施例提供的折叠壳体1处于中间悬停状态的一种结构示意图;图6为本申请实施例提供的折叠壳体1处于折合状态的结构示意图;图7为本申请实施例提供的折叠壳体1的分解示意图。本申请实施例中,折叠壳体1的第一壳体11与第二壳体12结构对称,当然,在其他实施例中,第一壳体11与第二壳体12的结构可以不对称。具体的,第一壳体11包括第一基板110、第一支撑板112及第一周侧板113。第一基板110与第一支撑板112相对设置,第一周侧板113连接于第一基板110、第一支撑板112之间。第二壳体12包括第二基板120、第二支撑板121及第二周侧板123。第二基板120与第二支撑板121相对设置,第二周侧板123连接于第二基板120、第二支撑板121之间。第一支撑板112背离第一基板110的一侧用于固定连接柔性显示屏2的第一非弯折区21;第二支撑板121背离第二基板120的一侧用于固定连接柔性显示屏2的第二非弯折区22。其中,第一基板110的尺寸与第一支撑板112的尺寸可以相同,也可以不同。第二基板120的尺寸与第二支撑板121的尺寸可以相同,也可以不同。本申请实施例中,第一基板110沿折叠壳体1的长度方向的尺寸大于第一支撑板112沿折叠壳体1的长度方向的尺寸;第二基板120沿折叠壳体1的长度方向的尺寸大于第二支撑板121沿折叠壳体1的长度方向的尺寸。折叠壳体1的长度方向可以参照附图中的X轴方向。换言之,第一基板110包括第一本体部1101和第一延伸部1102,第一本体部1101与第一基板110相对设置,第一延伸部1102朝向第二基板120的所在侧延伸。第二基板120包括第二本体部1201和第二延伸部1202,第二本体部1201与第二基板120相对设置,第二延伸部1202朝向第一基板110的所在侧延伸。折叠壳体1在处于展平状态时,第一延伸部1102远离第一本体部1101的一端与第二延伸部1202远离第二本体部1201的一端接触;第一延伸部1102、第二延伸部1202与柔性显示屏2的弯折区20之间形成第二容纳空间,转轴机构10收容于第二容纳空间内。折叠壳体1在处于折合状态时,第一支撑板112与第二支撑板121相对设置,分别用于支撑柔性显示屏2的第一非弯折区21 和第二非弯折区22;第一延伸部1102与第二延伸部1202相对设置,第一延伸部1102、第二延伸部1202及转轴机构10之间用于收容柔性显示屏2的弯折区20。本申请提供的折叠壳体1因具有以下实施例所描述的转轴机构10,因此第一壳体11、第二壳体12的运动轨迹更接近理论设计的圆弧轨迹。
请参照图8和图9,转轴机构10包括第一基座101、第一连接座102及第一转动组件103。第一壳体11转动连接第一基座101,第一壳体11可相对于第一基座101转动以实现展平、折合。具体的,第一壳体11与第一连接座102固定连接,第一连接座102位于第一基座101的一侧,并通过第一转动组件103与第一基座101转动连接。可以理解的,第一壳体11通过第一连接座102、第一转动组件103实现其与第一基座101的转动连接。其中,第一壳体11与第一连接座102的固定连接方式包括但不限于一体连接、螺纹连接、卡接、焊接、铆接等。第一连接座102的位置基于本申请的附图可以理解为第一连接座102位于第一基座101的左侧。通过使第一壳体11与第一连接座102固定连接可以减少第一壳体11与第一连接座102之间的配合间隙以及避免第一壳体11与第一连接座102之间的运动转换,便于第一壳体11与第一连接座102同步运动。
第一转动组件103位于第一基座101与第一连接座102之间。第一转动组件103包括第一转动件1030和第二转动件1031。第一转动件1030的一端转动连接第一基座101,第一转动件1030的另一端滑动连接第一连接座102。举例而言,第一转动件1030与第一基座101之间可以通过轴与孔的配合、圆弧轨迹槽与圆弧滑动部的配合直接转动连接,也可通过销轴等其他轴类部件形成转动连接。本申请实施例中以第一转动件1030与第一基座101之间通过第一转轴1032转动连接为例。第一转动件1030与第一连接座102之间可以通过滑轨与滑块、滑槽与滑块的配合实现滑动连接。第二转动件1031的一端转动连接第一基座101,第二转动件1031的另一端滑动连接第一连接座102。举例而言,第二转动件1031与第一基座101之间可以通过轴与孔的配合、圆弧轨迹槽与圆弧滑动部的配合直接转动连接,也可通过销轴等其他轴类部件形成转动连接。本申请实施例中以第二转动件1031与第一基座101之间通过第二转轴1033转动连接为例。第二转动件1031与第一连接座102之间可以通过滑轨与滑块、滑槽与滑块的配合实现滑动连接。第一转动件1030相对于第一基座101转动的第一转动轴线与第二转动件1031相对于第一基座101转动的第二转动轴线平行且不共线。由于本申请实施例中第一转动件1030与第一基座101之间通过第一转轴1032转动连接,第二转动件1031与第一基座101之间通过第二转轴1033转动连接,因此第一转动轴线可以理解为第一转轴1032或第一转轴1032的中轴线,第二转动轴线可以理解为第二转轴1033或第二转轴1033的中轴线。第一转动轴线与第二转动轴线平行且不共线可以理解为第一转轴1032与第二转轴1033平行且不共线。换言之,第一转轴1032与第二转轴1033平行且错位设置。其中,第一转动轴线与第二转动轴线皆平行于转轴机构10的中轴线。转轴机构10的中轴线可参照附图中的M线。第一转动轴线与第二转动轴线平行便于实现第一转动件1030与第二转动件1031同向转动。
第一壳体11、第一转动组件103中的一者可以作为折叠壳体1的左侧实现展平、折合的主动件,另一者作为折叠壳体1的左侧实现展平、折合的从动件,第一转轴1032、第二转轴1033可以皆为固定轴。当然,在其他实施例中,第一转轴1032和第二转轴1033可以作为折叠壳体1的左侧实现展平、折合的主动件,第一转动组件103作为第一转轴1032、第二转轴1033与第一壳体11之间传递运动和动力的传动件,第一壳体11作为折叠壳体1的左侧实现展平、折合的从动件。当第一壳体11作为主动件时,可通过用户作用的外力实现第一壳体11相对于第一基座101的转动,并带动第一转动件1030、第二转动件1031相对于第一基座101的转动,以实现展平、折合。当第一转动组件103作为主动件时,可在折叠壳体1内部设置相应的驱动结构(例如:电机等),通过驱动结构的作用实现第一转动件1030、第二转动件1031相对于第一基座101的转动,并带动折叠壳体1相对于第一基座101的转动,以实现展平、折合。当第一转轴1032、第二转轴1033作为主动件时,可在折叠壳体1内部设置相应的驱动结构(例如:电机等),通过驱动结构的作用实现第一转轴1032、第二转轴1033的转动,并带动第一转动件1030、第二转动件1031相对于第一基座101的转动,通过第一转动件1030、第二转动件1031相对于第一基座101的转动带动第一壳体11相对于第一基座101的转动,以实现展平、折合。以下实施例中,在未明确说明的情况下,以第一壳体11作为折叠壳体1的左侧实现展平、折合的主动件,第一转动组件103作为折叠壳体1的左侧实现展平、折合的从动件,第一转轴1032、第二转轴1033皆为固定轴为例。

由于转轴机构10包括第一基座101、第一连接座102及第一转动组件103,第一连接座102位于第一基座101的一侧,第一转动组件103位于第一连接座102与第一基座101之间,并包括第一转动件1030和第二转动件1031,而第一转动件1030的一端、第二转动件1031的一端分别与第一基座101转动连接,第一转动件1030的另一端、第二转动件1031的另一端分别与第一连接座102滑动连接,使得第一连接座102与第一转动件1030、第二转动件1031之间只可相对滑动而无法转动,从而提高第一连接座102与第一转动件1030、第二转动件1031相对于第一基座101同步转动的精确性。此外,由于第一转动件1030相对于第一基座101转动的第一转动轴线与第二转动件1031相对于第一基座101转动的第二转动轴线平行且不共线,使得第一转动件1030、第二转动件1031可同向转动,同时减小了第一转动组件103、第一基座101及第一连接座102之间的配合间隙,减少了转轴机构10的转动虚位、晃动,从而可进一步提高第一连接座102与第一转动件1030、第二转动件1031相对于第一基座101同步转动的精确性,使得转轴机构10在应用于折叠壳体1时对于第一壳体11的运动控制更加精确。

由于折叠壳体1处于折合状态时,第一支撑件170靠近第一基座101的一端朝向靠近第一连接座102的一侧倾斜,第二支撑件180靠近第一基座101的一端朝向靠近第二连接座104的一侧倾斜,即第一支撑件170远离第一基座101的一端与第二支撑件180远离第一基座101的一端之间的距离小于第一支撑件170靠近第一基座101的一端与第二支撑件180靠近第一基座101的一端之间的距离。换言之,在第一驱动件171、第二驱动件181的驱动下,第一支撑件170与第二支撑件180在折叠壳体1处于折合状态时形成了远离第一基座101的一端较窄,靠近第一基座101的一端较宽的容纳空间。结合第一支撑件170固定连接柔性显示屏2的第一子弯折区201,第二支撑件180固定连接柔性显示屏2的第三子弯折区203,第一壳体11与第二壳体12在折叠壳体1处于折合状态时相对设置,即柔性显示屏2的第一非弯折区21和第二非弯折区22相对设置,第一基座101与柔性显示屏2的第二子弯折区202之间未连接,第二子弯折区202呈自由弯折,可实现柔性显示屏2在折合状态时近似呈水滴型。
一实施例中,如图28所示,第一支撑件170的一端转动连接第一连接座102。第一驱动件171的一端转动连接第二基座106。第一驱动件171的另一端活动连接第一支撑件170的另一端。可选的,第一驱动件171与第一支撑件170之间的活动连接方式可以是转动连接、滑动连接、滚动连接中的一种。第一支撑件170在第一驱动件171和第一连接座102的作用下实现展平或倾斜。本实施例中,第一支撑件170、第一驱动件171和第一连接座102之间相互连接,可实现相互联动。此外,第一驱动件171和第一连接座102驱动第一支撑件170展平、倾斜可提高第一支撑件170运动的可靠性,减少第一驱动件171与第一支撑件170之间、第一连接座102与第一支撑件170的运动转换,提高转轴机构10的可靠性以及降低成本。
第二支撑件180的一端转动连接第二连接座104。第二驱动件181的一端转动连接第二基座106。第二驱动件181的另一端活动连接第二支撑件180的另一端。可选的,第二驱动件181与第二支撑件180之间的活动连接方式可以是转动连接、滑动连接、滚动连接中的一种。第二支撑件180在第二驱动件181和第二连接座104的作用下实现展平或倾斜。本实施例中,第二支撑件180、第二驱动件181和第二连接座104之间相互连接,可实现相互联动。此外,第二驱动件181和第二连接座104驱动第二支撑件180展平、倾斜可提高第二支撑件180运动的可靠性,减少第二驱动件181与第二支撑件180之间、第二连接座104与第二支撑件180的运动转换,提高转轴机构10的可靠性以及降低成本。
可选的,请参照图28至图32,第一支撑件170的一端转动连接第一连接座102。第一驱动件171的一端转动连接第二基座106。第一驱动件171的另一端滑动连接第一支撑件170。通过使第一驱动件171与第一支撑件170滑动连接,可以提高第一驱动件171与第一支撑件170之间相对于第二基座106转动的同步性,提高第一支撑件170展平、倾斜的精确度。

第一驱动件171与第一支撑件170中的一者包括第三滑块,第一驱动件171与第一支撑件170中的另一者包括第三滑槽,第三滑块位于第三滑槽内,以使第一支撑件170能够沿朝向靠近或远离第二基座106的方向滑动。一实施例中,第一驱动件171还包括与第一圆弧部1710相连的第三滑块1711。第一支撑件170具有第三滑槽1701。第三滑槽1701的开口朝向第一驱动件171的所在侧。第三滑块1711位于第三滑槽1701内。由于第一驱动件171与第一支撑件170之间滑动连接,因此第一驱动件171与第一支撑件170只可相对滑动而无法转动,从而提高第一驱动件171与第一支撑件170同步转动的精确性,且转轴机构10的设计更简单。在其他实施例中,可以在第一驱动件171上形成滑槽,在第一支撑件170上形成滑块,实现第一驱动件171与第一支撑件170的滑动连接。第一支撑件170在折叠壳体1从展平状态切换至折合状态的过程中朝向远离第二基座106的一侧滑动。

第二驱动件181的另一端滑动连接第二支撑件180。通过使第二驱动件181与第二支撑件180滑动连接,可以提高第二驱动件181与第二支撑件180之间相对于第二基座106转动的同步性,提高第二支撑件180展平、倾斜的精确度。
具体的,请参照图28至图30,第二驱动件181和第二基座106中的一者包括第三圆弧部,第二驱动件181和第二基座106中的另一者具有第三圆弧槽,第三圆弧部位于第三圆弧槽内,用于带动第二支撑件180绕第一圆弧槽的中心轴线转动。一实施例中,第二驱动件181包括第三圆弧部1810。第二基座106具有第三圆弧槽1061。第三圆弧部1810位于第三圆弧槽1061内,用于带动第二支撑件180绕第三圆弧槽1061的中心轴线转动。由于第二基座106在沿折叠壳体1的厚度方向的尺寸较大,因此在第二基座106上加工第三圆弧槽1061较容易,而第二驱动件181的尺寸较小,更便于形成第三圆弧部1810。当然,在其他实施例中,可以在第二驱动件181上形成圆弧槽,在第二基座106上形成圆弧部,以实现第二驱动件181与第二基座106的转动连接。此外,由于第二驱动件181与第二支撑件180通过第三圆弧槽1061与第三圆弧部1810转动连接,因此可通过设计第三圆弧槽1061实现第二驱动件181的转动轴心位于理论设计位置,相较于通过转轴转动连接的方式更灵活,且可以避免第二驱动件181对柔性显示屏2的运动阻碍。当然,在其他实施方式中,第二驱动件181与第二基座106之间还可以通过转轴转动连接,此时,第二驱动件181的转动轴心即转轴的中轴线。
第二驱动件181与第二支撑件180中的一者包括第六滑块,第二驱动件181与第二支撑件180中的另一者包括第六滑槽,第六滑块位于第六滑槽内,以使第二支撑件180能够沿朝向靠近或远离第二基座106的方向滑动。第二驱动件181还包括与第三圆弧部1810相连的第六滑块1811。第二支撑件180具有第六滑槽1801。第六滑槽1801的开口朝向第二驱动件181的所在侧。第六滑块1811位于第六滑槽1801内。由于第二驱动件181与第二支撑件180之间滑动连接,因此第二驱动件181与第二支撑件180只可相对滑动而无法转动,从而提高第二驱动件181与第二支撑件180同步转动的精确性,且转轴机构10的设计更简单。在其他实施例中,可以在第二驱动件181上形成滑槽,在第二支撑件180上形成滑块,实现第二驱动件181与第二支撑件180的滑动连接。第二支撑件180在折叠壳体1从展平状态切换至折合状态的过程中朝向远离第二基座106的一侧滑动。
