折叠装置200包括第一壳体110、第二壳体120和转动机构100,第一壳体110设有第一安装槽1,第二壳体120设有第二安装槽2,第一安装槽1和第二安装槽2连通形成安装槽。转动机构100安装于安装槽,并与第一壳体110和第二壳体120固定连接,以实现第一壳体110和第二壳体120之间的转动连接。第一壳体110和第二壳体120可通过转动机构100相对转动,使得折叠装置200在折叠状态和展开状态之间相互切换。
其中,第一壳体110和第二壳体120的相对转动使得折叠装置200在折叠状态,是指第一壳体110和第二壳体120通过转动机构100转动,且彼此相互靠近;第一壳体110与第二壳体120承载显示屏300的面相对。实际上,在应用过程中,折叠装置200完全折叠状态下,装于第一壳体110和第二壳体120的显示屏300折叠后,显示屏300位于第一显示部分310的显示面340和位于第二显示部分320的显示面340会有部分接触,当然,也可以完全接触。第一壳体110和第二壳体120相对转动使得折叠装置200在半展开状态,是指第一壳体110和第二壳体120通过转动机构100转动,且彼此相互远离,第一壳体110和第二壳体120之间的夹角越来越大,可以接近90度或者等于90度。第一壳体110和第二壳体120相对转动使得折叠装置200在展开状态,是指第一壳体110和第二壳体120通过转动机构100转动,且彼此相互远离,第一壳体110和第二壳体120之间的夹角继续增大,可以接近180度或者等于180度。
第一壳体110、第二壳体120和转动机构100沿着X方向依次设置且三者之间的尺寸之和为折叠装置200在X方向上的尺寸(包括装配公差和三者之间的装配缝隙)。折叠装置200在X方向上的尺寸与显示屏300及电子设备沿X方向的尺寸相同。当然,包括允许的公差范围。第一壳体110、第二壳体120和转动机构100沿Y方向的尺寸相同,所述的尺寸可以允许存在装配或者生产公差。第一壳体110、第二壳体120和转动机构100沿Y方向的尺寸即为折叠装置200在Y方向的尺寸,折叠装置200在Y方向的尺寸与显示屏300及电子设备沿Y方向的尺寸相同。当然,也可以允许有少量偏差(装配和生产公差)。显示屏300安装于折叠装置200,且安装面350与折叠装置200固定连接。具体的,第一壳体110承载第一显示部分310,第二壳体120承载第二显示部分320。换言之,第一显示部分310安装于第一壳体110,第二显示部分320安装于第二壳体120。其中,转动机构100与可折叠部分330相对设置。
结合图1,第一壳体110和第二壳体120通过转动机构100相对转动,通过第一壳体110和第二壳体120相对靠近带动显示屏300折叠,以使折叠式电子设备500折叠。当折叠式电子设备500处于折叠状态时,显示屏300的可折叠部分330发生弯折,第一显示部分310和第二显示部分320相对设置。此时,显示屏300处于第一壳体110和第二壳体120 之间,显示屏300的外露面积小,可大大降低显示屏300被损坏的概率,实现对显示屏300的有效保护。
请一并参阅图2和图4,第一壳体110和第二壳体120通过转动机构100相对转动,通过第一壳体110和第二壳体120相对远离带动显示屏300展开,以使折叠式电子设备500展开至半展开状态。当折叠式电子设备500处于半展开状态时,第一壳体110和第二壳体120展开至夹角为α,第一显示部分310和第二显示部分320相对展开,并带动可折叠部分330展开。此时,第一显示部分310和第二显示部分320之间的夹角为α。本实施例中,α为90度。在其它实施例中,α也可以大约为90度,也可以是80度、85度、95度或100度等。
请一并参阅图3和图4,第一壳体110和第二壳体120通过转动机构100相对转动,通过第一壳体110和第二壳体120相对远离带动显示屏300进一步展开,直至折叠式电子设备500展平。当折叠装置200处于展开状态时,第一壳体110和第二壳体120之间的夹角为β。可折叠部分330展平,第一显示部分310和第二显示部分320相对展开。此时,第一显示部分310、第二显示部分320和可折叠部分330之间的夹角均为β,显示屏300具有大面积的显示区域,实现折叠式电子设备500的大屏显示,提高用户的使用体验。本实施例中,β为180度。在其它实施例中,β也可以大约为180度,可以是170度、175度、185度和190度等。

请一并参阅图13,图13是图12所示柔性支撑件10另一状态的结构示意图。
柔性支撑件10处于弯折状态时,第一子弯折部161的第二子柔性段1613和第二子弯折部162的第四子柔性段1623朝着相同方向发生弯折,且第二子柔性段1613和第四子柔性段1623之间形成间隙。第一子刚性段1611和第二子刚性段1621形状保持不变,并在其延伸方向错位。第一子弯折部161的第一子柔性段1612和第二子弯折部162的第三子柔性段1622朝着相同方向发生弯折,且第一子柔性段1612和第三子柔性段1622之间形成间隙。第三子弯折部171的第六子柔性段1713和第四子弯折部172的第八子柔性段1723朝着相同方向发生弯折,且第六子柔性段1713和第八子柔性段1723之间形成间隙。第三子刚性段1711和第四子刚性段1721形状保持不变,并在其延伸方向错位。第三子弯折部171的第五子柔性段1712和第四子弯折部172的第七子柔性段1722朝着相同方向发生弯折,且第五子柔性段1712和第七子柔性段1722之间形成间隙。
本实施例中,柔性支撑件10弯折形成的避让空间18为水滴形状,从而使得避让空间 18的形状更加适配显示屏300弯折形成的形状,进一步避免柔性支撑件10挤压显示屏300对显示屏300造成损坏,同时,还可以避免显示屏300产生折痕等不良现象,延长显示屏300的使用寿命。
本实施例中,柔性支撑件10处于弯折状态时,形成避让空间18,该避让空间18可以为显示屏300的可折叠部分330提供弯折空间,从而避免显示屏300的可折叠部分330发生弯折时挤压柔性支撑件10,对显示屏300造成损坏。同时,也可以避让显示屏300弯折时形成的R角,使得显示屏300的可折叠部分330不会出现较大角度弯折,避免显示屏300产生折痕等不良现象,有助于延长显示屏300的使用寿命。并且,由于柔性支撑件10可以发生弯折,使得柔性支撑件10在弯折状态下的X方向的尺寸减小,从而可以减小转动机构100的厚度,有利于折叠式电子设备500的轻薄化。
通过在第一弯折部16的第一子弯折部161和第二子弯折部162之间设置间隙,使得第二子弯折部162弯折后可以为第一子弯折部161提供弯折空间,增加第一子弯折部161的弯折程度;通过在第二弯折部17的第三子弯折部171和第四子弯折部172之间设置间隙,使得第四子弯折部172弯折后可以为第三子弯折部171提供弯折空间,增加第三子弯折部171的弯折程度,从而进一步增加柔性支撑件10弯折形成的避让空间18,进一步为显示屏300提供弯折空间,并且进一步减小柔性支撑件10在折叠状态时的Z方向的尺寸。
其中,第一弯折部16、第二弯折部17和刚性部15的长度和比例,以及第一弯折部16和第二弯折部17中柔性段和刚性段的长度或比例,或者柔性段和刚性段的数量可以根据实际情况进行调整。以使柔性支撑件10处于折叠状态时具有不同的形状,从而使柔性支撑件10可以进一步适配显示屏300的可折叠部分330处于弯折状态时的形状,进一步为显示屏300提供弯折空间,避免显示屏300产生折痕等不良现象,延长显示屏300的使用寿命。
在一种实施方式中,第一弯折部16、第二弯折部17和刚性部15的长度比例为1:1:1。第一弯折部16中具有两个柔性段和一个刚性段,两个柔性段的长度相同,刚性段和每一柔性段的长度比例均为2:1。第二弯折部17中具有两个柔性段和一个刚性段,两个柔性段的长度相同,刚性段和每一柔性段的长度比例为2:1。
请一并参阅图6,柔性支撑件10承载于固定基座30。其中,第一摆臂25的第一转动部254与柔性支撑件10的第一连接轴转动连接,第二摆臂27的第二转动部与柔性支撑件10的第二连接轴转动连接。第一摆臂25和第二摆臂27相对固定基座30转动时,可以带动柔性支撑件10在弯折和展开状态切换。
具体的,请一并参阅图3,折叠式电子设备500处于展开状态时,第一门板40和第二门板50之间的夹角为β。其中,β为180度。第一摆臂25的第一转动体251和两个第一辅助转动体253朝向固定基座30内滑动,至第一转动体251收容于第一转动槽325内,第一摆臂25的端部由第一通孔13露出。第二摆臂27的第二转动体和两个第二辅助转动体朝向固定基座30内滑动,至第二转动体收容于第二转动槽327内,第二摆臂27的端部由第二通孔14露出。柔性支撑件10不发生弯折而处于展平状态。
请一并参阅图10和图14,图14是图5所示转动机构100处于折叠状态时的结构示意图。
第一门板40和第二门板50朝相互靠近的方向转动时,第一门板40通过第一固定板 26带动第一摆臂25顺时针旋转,第一转动体251和两个第一辅助转动体253朝向远离固定基座30方向滑动,带动柔性支撑件10靠近第一侧部11的部分朝着顺时针方向发生弯折;第二门板50通过第二固定板28带动第二摆臂27逆时针旋转,第二转动体和两个第二辅助转动体朝向远离固定基座30方向滑动,带动柔性支撑件10靠近第二侧部12的部分朝着逆时针方向发生弯折,同时带动第二固定板28和第二门板50逆时针旋转。此时,柔性支撑件10处于弯折状态,第一门板40和第二门板50相对折叠,转动机构100处于折叠状态。
请参阅图14和图15,图15是图1所示折叠式电子设备500的局部结构示意图。其中,图15所示折叠式电子设备500仅示出了转动机构100和显示屏300。
折叠式电子设备500处于折叠状态时,柔性支撑件10发生弯折,且第一侧部11和第二侧部12朝远离固定基座30方向移动,刚性部15朝靠近固定基座30方向运动,并收容于凹槽317内,从而形成避让空间18。凹槽317为柔性支撑件10的弯折提供了空间,使得柔性支撑件10能够顺利发生弯折并形成避让空间18,同时,也可以避免固定基座30挤压柔性支撑件10对柔性支撑件10造成损坏。其中,显示屏300的可折叠部分330位于转动机构100的内侧。其中,部分可折叠部分330位于第一门板40和第二门板50之间,且与第一门板40和第二门板50间隔设置,部分可折叠部分330与柔性支撑件10相对,并位于避让空间18内。通过柔性支撑件10弯折可避让可折叠部分330弯折时形成的R角,使得可折叠部分330不会出现较大角度弯折,避免显示屏300产生折痕等不良现象,有助于延长显示屏300的使用寿命。
同时,显示屏300与柔性支撑件10之间具有间隙,从而可以避免显示屏300与柔性支撑件10之间发生挤压对显示屏300造成损坏,也可以避免在可靠性测试中柔性支撑件10碰撞显示屏300而对显示屏300造成损坏。并且,通过设置可弯折的柔性支撑件10,使得柔性支撑件10在弯折状态下的Z方向的尺寸减小,从而可以减小转动机构100的厚度,有利于折叠式电子设备500的轻薄化。

第一弯折部16b和第二弯折部17b由柔性材料制备。具体的,第一弯折部16b和第二弯折部17b可以由橡胶材料制备,也可以由热塑性弹性体或其它柔性材料制备。刚性部15b由刚性材料制备,如金属材料。示例性的,刚性部15b由不锈钢、铝或铜等材料制备。采用柔性材料制备的第一弯折部16b和第二弯折部17b受力易发生形变,从而可以为显示屏300的弯折部分提供弯折空间,避免显示屏300产生折痕等不良现象,延长显示屏300的使用寿命。采用刚性材料制备的刚性部15b不易发生变形,具有较高的强度,起到增加柔性支撑件10b的强度的作用,同时,可以使柔性支撑件10b处于折叠状态时可以形成预设形状,以使柔性支撑件10b能够更加适配显示屏300的弯折部分。
请参阅图18,图18是本申请第四实施例提供的折叠式电子设备500中的柔性支撑件10的结构示意图。
柔性支撑件10c包括第一侧部11c、第二侧部12c、第一弯折部16c、第二弯折部17c和刚性部15c。第一弯折部16c和第二弯折部17c分别连接于刚性部15c沿X方向的相对两侧,且第一弯折部16c和第二弯折部17c相对刚性部15c对称。第一弯折部16c包括第一刚性段164、第一柔性段163和第二柔性段165,第一柔性段163和第二柔性段165分别连接于第一刚性段164的相对两侧,第一柔性段163与第一侧部11c连接,第二柔性段165与刚性部15c连接。第二弯折部17c包括第二刚性段174、第三柔性段173和第四柔性段175,第三柔性段173和第四柔性段175分别连接于第二刚性段174的相对两侧,第三柔性段173与刚性部15c连接,第四柔性段175与第二侧部12c连接。
第一柔性段163、第二柔性段165、第三柔性段173和第四柔性段175均由柔性材料制备,具体的,可以为橡胶材料、热塑性弹性体或其它柔性材料。刚性部15c、第一刚性段164和第二刚性段174均由刚性材料制备,如金属材料。转动机构100处于折叠状态时,第一柔性段163、第二柔性段165、第三柔性段173和第四柔性段175均发生弯折,从而使柔性支撑件10弯折并形成避让空间,用以为显示屏300提供弯折空间,避免显示屏300产生折痕等不良现象,延长显示屏300的使用寿命。通过设置第一刚性段164和第二刚性段174可以进一步增加柔性支撑件10的强度。并且,当转动机构100处于折叠状态时,柔性支撑件10可以弯折形成预设形状,以使柔性支撑件10能够更加适配显示屏300的可折叠部分。
