在本实现方式中,折叠装置处于闭合状态时,第一支撑件和第二支撑件部分伸入中壳的内侧空间,中壳的内侧空间中位于第一支撑件与第二支撑件之间的部分空间被释放,形成容屏空间,柔性显示屏可以部分伸入中壳的内侧空间,提高了空间利用率,使得电子设备的部件排布更为紧凑,有利于电子设备的小型化。
一种可能的实现方式中,中壳还可以包括两个端盖板,两个端盖板分别固定于外盖板的两端,与外盖板共同围设出中壳的内侧空间。其中,两个端盖板可以与外盖板为一体成型结构,或者通过组装方式彼此固定。
一种可能的实现方式中,第一壳体与第二壳体处于打开状态时,第一支撑件的支撑面与第二支撑件的支撑面拼接形成折弯区支撑面。
在本实现方式中,折叠装置的转动机构能够在打开状态中,通过折弯区支撑面充分支撑柔性显示屏的折弯部,使得柔性显示屏不易在用户的按压下发生凹陷等问题,有利于提高柔性显示屏的使用寿命和可靠性。
其中,第一支撑件的支撑面与第二支撑件的支撑面拼接的情况,可以包括第一支撑件的 支撑面与第二支撑件的支撑面连接、两者之间无缝隙的情况,也可以包括第一支撑件的支撑面与第二支撑件的支撑面相互靠近、两者之间存在小缝隙的情况。当第一支撑件的支撑面与第二支撑件的支撑面之间存在小缝隙时,用户按压柔性显示屏对应于该缝隙的区域,柔性显示屏的对应区域也不会出现明显凹坑,折弯区支撑面能够为柔性显示屏提供强力支撑。
一种可能的实现方式中,第一支撑件朝向第二支撑件的一侧可以设置一个或多个缺口,第二支撑件朝向第一支撑件的一侧可以设置一个或多个缺口,第一支撑件的缺口与第二支撑件的缺口相对应,这部分缺口用于避免第一支撑件和第二支撑件在折叠装置运动的过程中,与转动机构的其他结构件发生干涉,也即用于实现避让,从而提高转动机构和折叠装置的运动可靠性。
其中,这部分缺口的面积也是比较小的,柔性显示屏对应于这部分缺口的区域可能在用户的按压下稍微下陷,但是仍不会产生明显凹坑。此外,在一些实现方式中,柔性显示屏可以在朝向折叠装置的一侧设置可弯曲且具有一定结构强度的支撑板或补强板,支撑板或补强板至少覆盖第一支撑件的缺口和第二支撑件的缺口,以提高柔性显示屏的抗按压强度。
一种可能的实现方式中,第一壳体靠近转动机构的一侧设有第一安装槽,第一支撑件安装于第一安装槽。第二壳体靠近转动机构的一侧设有第二安装槽,第二支撑件安装于第二安装槽。第一壳体与第二壳体处于打开状态时,中壳位于第一安装槽和第二安装槽,第一壳体及第二壳体遮盖外盖板;第一壳体与第二壳体处于闭合状态时,中壳部分伸出第一安装槽和第二安装槽,外盖板相对第一壳体及第二壳体露出。

在本实现方式中,外盖板形成弧形或类似弧形的形状,有助于提高电子设备处于闭合状态时的外观体验和握持体验。此外,外盖板的中部为平直部,使得外盖板的厚度较小, 折叠装置处于打开状态时的整体厚度较小,有利于电子设备的轻薄化。其中,外盖板的厚度为外盖板在垂直于平直部方向上的尺寸。
一种可能的实现方式中,第一壳体与第二壳体处于打开状态时,第一支撑件抵持外盖板的一侧边缘,第二支撑件抵持外盖板的另一侧边缘。
在本实现方式中,外盖板能够在折叠装置处于打开状态时,对第一支撑件和第二支撑件进行止位,以防止折叠装置在展开时过折,从而降低柔性显示屏的受力,提高柔性显示屏和电子设备的可靠性。

在本实现方式中,第一支撑件与中壳之间通过第一转轴实现单级实体轴的转动连接,第二支撑件与中壳之间通过第二转轴实现单级实体轴的转动连接。第一支撑件及第二支撑件与中壳之间的单级实体轴转动机构形成折叠装置的主运动机构,故而主运动机构零件数量少,零件配合关系简单,机构自由度为1,尺寸链短,累积误差小,因此主运动机构的控制精度高,提高了折叠装置的转动精度,有利于提高电子设备的用户使用体验。
其中,第一凸起可以连接外盖板的第一弯曲部和平直部,以提高外盖板的结构强度。第二凸起可以连接外盖板的第二弯曲部和平直部,以提高外盖板的结构强度。

在本实现方式中,通过设置中壳的转轴孔位置、第一支撑件的转轴孔位置以及第二支撑件的转轴孔位置,使得中壳与第一支撑件之间可以通过第一转轴转动连接,中壳与第二支撑件之间可以通过第二转轴转动连接,也即中壳与第一支撑件及第二支撑件之间可以通过实体轴转动连接,连接关系可靠,转动动作精确、稳定。
此外,第一凸起与第一支撑件的嵌入关系也可以使两者在平行于转动中心的方向上彼此限位,提高了转动连接结构的可靠性。第二凸起与第二支撑件的嵌入关系也可以使两者在平行于转动中心的方向上彼此限位,提高了转动连接结构的可靠性。

在本实现方式中,在折叠装置展开和折叠的过程中,第一同步摆臂相对第一支撑件的滑动和转动动作与第二同步摆臂相对第二支撑件的滑动和转动动作对称,从而使得第一支撑件和第二支撑件相对中壳的转动动作保持同步,也即同步相互靠近或相互远离,因此第一壳体和第二壳体相对中壳的转动动作同步性好,提高了折叠装置和电子设备的机构操作体验。
一种可能的实现方式中,中壳还包括第三凸起,第三凸起位于中壳的内侧空间且固定于外盖板。第三凸起可以设有安装槽,安装槽大致呈弧形,安装槽的中部相对安装槽的两侧向靠近外盖板的平直部的方向进一步凹陷。其中,当安装槽的深度较深时,安装槽也可以部分形成在外盖板的平直部。其中,安装槽可以包括多个依次连通的槽部,各槽部的底壁呈弧面,各槽部的侧壁可以设置有转动凹槽。其中,第三凸起可以连接外盖板的第一弯曲部、平直部以及第二弯曲部,以提高外盖板的结构强度。

在本实现方式中,第一同步摆臂的转动端、多个齿轮轴以及第二同步摆臂的转动端排布成弧形,也即同步组件的安装于中壳的部分结构排布成弧形,从而能够充分利用中壳的内侧空间的底部空间,使得中壳的内侧空间的顶部空间能够释放形成容屏空间,用于在电子设备闭合时,收容部分柔性显示屏,从而有利于提高电子设备的部件排布的紧凑性,减小电子设备的体积。

在本实现方式中,第一阻尼件的弹性件能够在外力作用下发生形变,从而使得第一阻尼件能够相对第一同步摆臂的活动端、在其转轴的两侧之间顺利移动,提高了第一阻尼件与第一同步摆臂的活动端的限位可靠性。
其中,第一阻尼件还可以包括缓冲件,缓冲件安装于支架的抵持部。其中,缓冲件可以采用刚度较小的材料(例如橡胶等),以在受到外力时,能够通过形变吸收冲击力,实现缓冲。由于缓冲件套设在支架的抵持部上,因此第一阻尼件通过具有缓冲作用的第一缓冲件抵持第一同步摆臂的活动端,有利于降低第一阻尼件的支架和第一同步摆臂的活动端在长时间相对运动的过程中发生磨损的风险,提高了第一阻尼件的限位可靠性,使得转动机构的可靠性更高。
一种可能的实现方式中,第二阻尼件的结构与第一阻尼件的结构相同,以简化折叠装置的物料种类,降低折叠装置的成本。

请一并参阅图1至图3,图1是本申请实施例提供的一种电子设备1000处于打开状态时的结构示意图,图2是图1所示电子设备1000的折叠装置100的部分分解结构示意图,图3是图1所示电子设备1000处于闭合状态时的结构示意图。其中,电子设备1000可以是手机、平板电脑、笔记本电脑等可折叠的电子产品。本申请实施例以电子设备1000是手机为例进行说明。
电子设备1000包括折叠装置100和柔性显示屏200,柔性显示屏200安装于折叠装置100。柔性显示屏200用于显示图像,折叠装置100用于带动柔性显示屏200运动。折叠装置100包括依次连接第一壳体10、转动机构20以及第二壳体30。转动机构20能够发生形变,以使第一壳体10与第二壳体30相对折叠和相对展开,也即折叠装置100能够折叠和展开。
如图1所示,第一壳体10与第二壳体30可以相对展开至打开状态,也即折叠装置100处于打开状态,以使电子设备1000处于打开状态。此时,柔性显示屏200随折叠装置100展开,柔性显示屏200展平。示例性的,第一壳体10与第二壳体30处于打开状态时,第一壳体10与第二壳体30可以大致呈180°。在其他一些实施例中,第一壳体10与第二壳体30处于打开状态时,两者之间的角度也可以相对180°存在少许偏差,例如165°、177°或者185°等。

一些实施例中,参阅图2,柔性显示屏200的第一非折弯部200a固定连接第一壳体10的支撑面102,还可以固定连接第一支撑件2的支撑面21的部分区域。示例性的,第一非折弯部200a与第一壳体10之间以及与第一支撑件2之间可以通过胶层粘接。其中,第一非折弯部200a固定连接第一壳体10的支撑面102是指两者彼此连接,且连接后第一非折弯部200a相对第一壳体10的支撑面102固定(即两者之间的位置关系不变)。第一非折弯部200a固定连接第一支撑件2的支撑面21的部分区域是指,第一非折弯部200a与第一支撑件2的支撑面21连接,且连接后第一非折弯部200a相对第一支撑件2的支撑面21的部分区域固定(即两者之间的位置关系不变),相对另一部分区域可以活动(即两者之间的位置关系可以发生变化)。
柔性显示屏200的第二非折弯部200c固定连接第二壳体30的支撑面302,还可以固定连接第二支撑件3的支撑面31的部分区域。示例性的,第二非折弯部200c与第二壳体30之间以及与第二支撑件3之间可以通过胶层粘接。其中,第二非折弯部200c固定连接第二壳体30的支撑面302是指两者彼此连接,且连接后第二非折弯部200c相对第二壳体30的支撑面302固定(即两者之间的位置关系不变)。第二非折弯部200c固定连接第二支撑件3的支撑面31的部分区域是指,第二非折弯部200c与第二支撑件3的支撑面31连接,且连接后第二非折弯部200c相对第二支撑件3的支撑面31的部分区域固定(即两者之间的位置关系不变),相对另一部分区域可以活动(即两者之间的位置关系可以发生变化)。
在本实施例中,柔性显示屏200的第一非折弯部200a与折叠装置100的第一支撑面401的固定连接面积(也即彼此固定的区域的面积)较大,第二非折弯部200c与折叠装置100的第二支撑面402的固定连接面积较大,故而折叠装置100与柔性显示屏200的非形变部分之间连接牢固,能够更好地带动柔性显示屏200展开和折叠。
其中,位于第一非折弯部200a与第一壳体10的支撑面102之间的胶层、位于第一非折弯部200a与第一支撑件2的支撑面21之间的胶层、位于第二非折弯部200c与第二壳体30的支撑面302之间的胶层以及位于第二非折弯部200c与第二支撑件3的支撑面31之间的胶层,可以是连续的整面胶层,也可以是点断式胶层,也可以是具有镂空区域的胶层,本申请实施例对胶层的具体方案不做严格限定。
一些实施例中,如图2所示,第一支撑件2的支撑面21和第一壳体10的支撑面102齐平,使得第一支撑面401能够为柔性显示屏200提供平整的强力支撑,从而提高用户的触控操作、画面观看等体验。示例性的,第一支撑件2的支撑面21和第一壳体10的支撑面102均为平面,且两者共面,第一支撑面401为平面,从而更好地支撑柔性显示屏200。此时,柔性显示屏200与第一支撑件2的支撑面21之间的胶层可以和柔性显示屏200与第一壳体10的支撑面102之间的胶层相等厚度。
可以理解的是,当第一支撑件2的支撑面21与第一壳体10的支撑面102彼此平行,但两者之间有少许错位时,可以通过柔性显示屏200与第一支撑件2的支撑面21之间的胶层和柔性显示屏200与第一壳体10的支撑面102之间的胶层的厚度的少许差异,使柔性显示屏200固定于第一支撑面401后,柔性显示屏200的相应区域为仍为平面区域,这种情况也认为第一支撑件2的支撑面21与第一壳体10的支撑面102齐平。
在其他一些实施例中,柔性显示屏200的第一非折弯部200a与第一支撑件2的支撑面21之间也可以无固定连接关系,也即两者之间无连接胶层,两者可以直接接触。此时,第一支撑件2的支撑面21与第一壳体10的支撑面102彼此平行,且第一支撑件2的支撑面21相对第一壳体10的支撑面102少许凸出,以使柔性显示屏200仍可以获得平面支撑,这种情况也认为第一支撑件2的支撑面21与第一壳体10的支撑面102齐平。
在其他一些实施例中,第一壳体10的支撑面102可以包括靠近第一支撑件2的平面部分和远离第一支撑件2的弧面部分,第一支撑件2的支撑面21为平面,第一支撑件2的支撑面21与第一壳体10的支撑面102的平面部分共面、或者平行且有少许错位,这种情况也认为第一支撑件2的支撑面21与第一壳体10的支撑面102齐平。在本实施例中,第一支撑面401可以支撑柔性显示屏200呈现3D显示效果。
其中,第二支撑件3的支撑面31、第二壳体30的支撑面302、以及这两者与柔性显示屏200的第二非折弯部200c之间的连接关系等的相关设计,可以参阅上述第一支撑件2的支撑面21、第一壳体10的支撑面102、以及这两者与柔性显示屏200的第一非折弯部200a之间的连接关系等的技术方案,本申请对此不再赘述。
一些实施例中,如图2所示,第一壳体10与第二壳体30相对展开至打开状态时,第一支撑件2与第二支撑件3相互靠近,第一支撑面401与第二支撑面402齐平。此时,第一支撑面401和第二支撑面402能够为柔性显示屏200提供平面支撑,使得柔性显示屏200平整、可进行大面积显示。
其中,第一支撑面401与第二支撑面402齐平的情况包括:第一支撑面401和第二支撑面402均为平面,并且两者共面;第一支撑面401和第二支撑面402均为平面,两者平行且有少许错位;第一支撑面401和第二支撑面402包括彼此靠近的平面部分和彼此远离的弧面部分,两个平面部分共面、或者平行且有少许错位,两个弧面部分用于使柔性显示屏200的两侧边缘弯曲,从而具有3D显示效果。

如图4所示,第一壳体10与第二壳体30处于打开状态时,第一支撑件2遮盖中壳1的部分内侧空间12,第二支撑件3遮盖中壳1的部分内侧空间12。此时,第一支撑件2与第二支撑件3彼此靠近,第一支撑件2的支撑面21与第二支撑件3的支撑面31之间的距离较小,转动机构20采用两板式结构即可在打开状态中对柔性显示屏200的折弯部200b 提供较为完整的平面支撑。
示例性的,第一壳体10与第二壳体30处于打开状态时,第一支撑件2的支撑面21与第二支撑件3的支撑面31拼接形成折弯区支撑面(21、31)。此时,折叠装置100的转动机构20能够在打开状态中,通过折弯区支撑面(21、31)充分支撑柔性显示屏200的折弯部200b,使得柔性显示屏200不易在用户的按压下发生凹陷等问题,有利于提高柔性显示屏200的使用寿命和可靠性。
可以理解的,第一支撑件2的支撑面21与第二支撑件3的支撑面31拼接的情况,可以包括第一支撑件2的支撑面21与第二支撑件3的支撑面31连接、两者之间无缝隙的情况,也可以包括第一支撑件2的支撑面21与第二支撑件3的支撑面31相互靠近、两者之间存在小缝隙的情况。当第一支撑件2的支撑面21与第二支撑件3的支撑面31之间存在小缝隙时,用户按压柔性显示屏200对应于该缝隙的区域,柔性显示屏200的对应区域也不会出现明显凹坑,折弯区支撑面(21、31)能够为柔性显示屏200提供强力支撑。
其中,第一支撑件2朝向第二支撑件3的一侧可以设置一个或多个缺口(细化描述参见后文),第二支撑件3朝向第一支撑件2的一侧可以设置一个或多个缺口(细化描述参见后文),第一支撑件2的缺口与第二支撑件3的缺口相对应,这部分缺口用于避免第一支撑件2和第二支撑件3在折叠装置100运动的过程中,与转动机构20的其他结构件发生干涉,也即用于实现避让,从而提高转动机构20和折叠装置100的运动可靠性。
可以理解的是,这部分缺口的面积也是比较小的,柔性显示屏200对应于这部分缺口的区域可能在用户的按压下稍微下陷,但是仍不会产生明显凹坑。此外,在一些实施例中,柔性显示屏200可以在朝向折叠装置100的一侧设置可弯曲且具有一定结构强度的支撑板或补强板,支撑板或补强板至少覆盖第一支撑件2的缺口和第二支撑件3的缺口,以提高柔性显示屏200的抗按压强度。

在本实施例中,外盖板11形成类似弧形的形状,有助于提高电子设备1000处于闭合状态时的外观体验和握持体验。此外,外盖板11的中部为平直部112,使得外盖板11的厚度(在垂直于平直部112方向上的尺寸)较小,折叠装置100处于打开状态时的整体厚度较小,有利于电子设备1000的轻薄化。
在另一些实施例中,外盖板11也可以呈弧形。在其他一些实施例中,外盖板11也可以呈半圆形、半椭圆形或其他形状。

其中,第一同步摆臂51的转动端511的齿轮511c与第二同步摆臂52的转动端521的齿轮521c之间通过齿轮组53啮合。齿轮组53可以包括多个齿轮轴531,多个齿轮轴531彼此啮合。第一同步摆臂51的转动端511的齿轮511c啮合齿轮组53中靠近第一同步摆臂51的端部齿轮轴531,第二同步摆臂52的转动端521的齿轮521c啮合齿轮组53中靠近第二同步摆臂52的端部齿轮轴531。示例性的,各齿轮轴531均包括本体531a、转轴531b及齿轮531c,转轴531b固定于本体531a的正面和/或背面,齿轮531c固定于本体531a的周侧面。
结合参阅图12和图13,第一同步摆臂51的转动端511、齿轮组53及第二同步摆臂52的转动端521可安装于中壳1的活动空间18。其中,第一同步摆臂51的转动端511转动连接中壳1。第一同步摆臂51的转动端511的转轴511b可以伸入活动空间18的部分转动凹槽162中。第二同步摆臂52的转动端521转动连接中壳1。第二同步摆臂52的转动端521的转轴521b可以伸入活动空间18的另一部分转动凹槽162中。齿轮组53的多个齿轮轴531可依次安装于活动空间18,各齿轮轴531均转动连接中壳1。各齿轮轴531的转轴531b可以伸入活动空间18的另一部分转动凹槽162中。
示例性的,第一同步摆臂51的转动端511、多个齿轮轴531以及第二同步摆臂52的 转动端521排布成弧形。在本实施例中,同步组件5的安装于中壳1的部分结构排布成弧形,从而能够充分利用中壳1的内侧空间12的底部空间,使得中壳1的内侧空间12的顶部空间能够释放形成容屏空间,用于在电子设备1000闭合时,收容部分柔性显示屏200,从而有利于提高电子设备1000的部件排布的紧凑性,减小电子设备1000的体积。
可以理解的是,齿轮组53中齿轮轴531的数量、尺寸等可以依据产品具体形态、尺寸等机型设计,本申请对此不做严格限定。其中,齿轮轴531数量越多、齿轮轴531的尺寸越小,能够释放更多的空间,齿轮组53的数量越少,齿轮轴531的尺寸越大,齿轮组53的传动累积误差更小,有利于提高运动准确性。
请再次参阅图9,同步组件5安装于中壳1,第一同步摆臂51的活动端512位于中壳1外侧,第二同步摆臂52的活动端522位于中壳1外侧。其中,第一同步摆臂51的活动端512用于活动连接第一支撑件2,在第一壳体10与第二壳体30相对折叠和相对展开的过程中,第一同步摆臂51的活动端512相对第一支撑件2滑动且转动。第二同步摆臂52的活动端522活动连接第二支撑件3,在第一壳体10与第二壳体30相对折叠和相对展开的过程中,第二同步摆臂52的活动端522相对第二支撑件3滑动且转动。
示例性的,第一支撑件2设有第一滑槽25,第一同步摆臂51的活动端512安装于第一滑槽25。其中,第一滑槽25的槽壁中部凹陷形成第一滑槽25的导向空间251。第一同步摆臂51的活动端512具有转轴512a,转轴512a可安装于第一滑槽25的导向空间251,转轴512a可以于第一滑槽25的导向空间251中滑动和转动。通过第一滑槽25的导向空间251与第一同步摆臂51的活动端512的转轴512a之间的配合,能够引导第一同步摆臂51的活动端512于第一滑槽25的滑动方向,使得第一同步摆臂51的活动端512与第一支撑件2之间的相对滑动动作更易实现、控制精度更高。
第二支撑件3设有第二滑槽35,第二同步摆臂52的活动端522安装于第二滑槽35。其中,第二滑槽35的槽壁中部凹陷形成第二滑槽35的导向空间351。第二同步摆臂52的活动端522具有转轴522a,转轴522a可安装于第二滑槽35的导向空间351,转轴522a可以于第一滑槽25的导向空间251中滑动和转动。通过第二滑槽35的导向空间351与第二同步摆臂52的活动端522的转轴522a之间的配合,能够引导第二同步摆臂52的活动端522于第二滑槽35的滑动方向,使得第二同步摆臂52的活动端522与第一支撑件2之间的相对滑动动作更易实现、控制精度更高。
一些实施例中,如图9所示,第一支撑件2还设有第一限位槽26,第一限位槽26连通第一滑槽25。第一阻尼件6可以安装于第一限位槽26且部分伸入第一滑槽25。第一壳体10与第二壳体30处于打开状态时,第一阻尼件6抵持第一同步摆臂51的活动端512。具体的,第一限位槽26连通第一滑槽25的导向空间251,第一阻尼件6可以抵持第一同步摆臂51的活动端512的转轴512a。
第二支撑件3还设有第二限位槽36,第二限位槽36连通第二滑槽35。第二阻尼件7可以安装于第二限位槽36且部分伸入第二滑槽35。第一壳体10与第二壳体30处于打开状态时,第二阻尼件7抵持第二同步摆臂52的活动端522。具体的,第二限位槽36连通第二滑槽35的导向空间351,第二阻尼件7可以抵持第二同步摆臂52的活动端522的转轴522a。
请一并参阅图14和图15,图14是图9所示第一阻尼件6的结构示意图,图15是图14所示第一阻尼件6的分解结构示意图。
一些实施例中,第一阻尼件6可以是弹性阻尼。第一阻尼件6包括支架61和弹性件62。支架61为刚性结构,在外力作用下不易发生形变。弹性件62为弹性结构,在外力作用下容易发生形变。支架61包括控制部611和抵持部612,弹性件62的一端安装于支架61的控制部611、另一端抵持第一限位槽26的槽壁。此时,支架61的抵持部612可以在弹性件62的弹性力下抵持第一限位槽26的另一侧槽壁。第一壳体10与第二壳体30处于打开状态时,支架61的抵持部612卡接第一同步摆臂51的活动端512。
在本实施例中,第一阻尼件6的弹性件62能够在外力作用下发生形变,从而使得第一阻尼件6能够相对第一同步摆臂51的活动端512、在其转轴的两侧之间顺利移动,提高了第一阻尼件6与第一同步摆臂51的活动端512的限位可靠性。
其中,第一阻尼件6还可以包括缓冲件63,缓冲件63安装于支架61的抵持部612。其中,缓冲件63可以采用刚度较小的材料(例如橡胶等),以在受到外力时,能够通过形变吸收冲击力,实现缓冲。由于缓冲件63套设在支架61的抵持部612上,因此第一阻尼件6通过具有缓冲作用的第一缓冲件63抵持第一同步摆臂51的活动端512,有利于降低第一阻尼件6的支架61和第一同步摆臂51的活动端512在长时间相对运动的过程中发生磨损的风险,提高了第一阻尼件6的限位可靠性,使得转动机构20的可靠性更高。
其中,第二阻尼件7的结构可以与第一阻尼件6的结构相同,以简化折叠装置100的物料种类,降低成本。本申请实施例不再对第二阻尼件7的结构进行赘述。
可以理解的是,上述实施例通过举例方式示意出一种阻尼件的结构,本申请实施例的阻尼件也可以有其他结构,例如采用弹性橡胶块等。上述实施例的阻尼件在折叠装置100处于打开状态时对同步组件5进行限位,在其他一些实施例中,折叠装置100也可以包括在闭合状态对同步组件5进行限位的阻尼件,限位方式及阻尼件结构可以参阅上述实施例。
请再次参阅图9,一些实施例中,第一支撑件2包括第一支撑板27、第一凸块28和第二凸块29。第一支撑件2的支撑面21形成于第一支撑板27。第一支撑板27还包括固定面271,第一支撑板27的固定面271与支撑面21相背设置。第一凸块28和第二凸块29均固定于第一支撑板27的固定面271。第一凸块28的高度小于第二凸块29的高度。其中,第一支撑件2的转轴孔23可以部分形成于第一支撑板27、部分形成于第一凸块28,第一凸块28的设置既能够降低转轴孔23的排布难度,同时也能够避免第一支撑件2的位于转轴孔23周边的部分的结构强度不足。其中,第一支撑件2的第一滑槽25和第一限位槽26可以形成于第二凸块29。第一支撑件2的紧固孔22也可以形成于第二凸块29。
其中,第二支撑件3包括第二支撑板37、第三凸块38和第四凸块39。第二支撑件3的支撑面31形成于第二支撑板37。第二支撑板37还包括固定面371,第二支撑板37的固定面371与支撑面31相背设置。第三凸块38和第四凸块39均固定于第二支撑板37的固定面371。其中,第二支撑件3的转轴孔33可以部分形成于第二支撑板37、部分形成于第三凸块38,第三凸块38的设置既能够降低转轴孔33的排布难度,同时也能够避免第二支撑件3的位于转轴孔33周边的部分的结构强度不足。其中,第二支撑件3的第二滑槽35和第二限位槽36可以形成于第四凸块39。第二支撑件3的紧固孔32也可以形成于第四凸 块39。
可以理解的是,第一支撑件2和第二支撑件3以支撑板为基底,在需要设置连接结构的位置处设置相应凸块以实现结构排布,该方式能够简化第一支撑件2和第二支撑件3的结构、降低整体重量。
其中,第一支撑件2的第一缺口24贯穿第一凸块28和第一支撑板27。第一支撑件2还可以设有第三缺口210,第三缺口210形成于第一支撑板27,第三缺口210用于避让同步组件5的第一同步摆臂51。第二支撑件3的第二缺口34贯穿第三凸块38和第二支撑板37。第二支撑件3还可以设有第四缺口310,第四缺口310形成于第二支撑板37,第四缺口310用于避让同步组件5的第二同步摆臂52。
其中,第一支撑件2可以为一体成型的结构件,第二支撑件3可以为一体成型的结构件。在本实施例中,由于第一支撑件2和第二支撑件3均为一体成型的结构件,有利于降低转动机构20的零件数,提高转动机构20的运动可靠性。在其他一些实施例中,第一支撑件2也可以通过多个部件组装形成一体式结构,第二支撑件3也可以通过多个部件组装形成一体式结构。本申请不对第一支撑件2和第二支撑件3的具体结构、加工方式等进行严格限定。
以下主要结合电子设备1000的多个剖面图,对电子设备1000的结构进行说明。
请一并参阅图16和图17,图16是图1所示电子设备1000沿B-B处剖面的截面图,图17是图3所示电子设备1000沿C-C处剖开的截面图。也即,图16所示电子设备1000处于打开状态,图17所示电子设备1000处于折叠状态。
第一支撑件2的一端通过第一转轴41转动连接中壳1,第一支撑件2的另一端固定地安装于第一壳体10的第一安装槽101。也即,第一支撑件2的一端转动连接中壳1、另一端固定连接第一壳体10。第一支撑件2的支撑面21与第一壳体10的支撑面102拼接形成第一支撑面401。第二支撑件3的一端通过第二转轴42转动连接中壳1,第二支撑件3的另一端固定地安装于第二壳体30的第二安装槽301。也即,第二支撑件3的一端转动连接中壳1、另一端固定连接第二壳体30。第二支撑件3的支撑面31与第二壳体30的支撑面302拼接形成第二支撑面402。
如图16所示,第一壳体10与第二壳体30相对展开至打开状态时,第一支撑件2与第二支撑件3相互靠近,第一支撑面401与第二支撑面402齐平。第一支撑面401和第二支撑面402共同支撑柔性显示屏200,柔性显示屏200展平。
如图17所示,第一壳体10与第二壳体30相对折叠至闭合状态时,第一支撑件2与第二支撑件3彼此远离,第一支撑面401与第二支撑面402在远离中壳1的方向上逐渐靠近。第一支撑面401支撑部分柔性显示屏200,第二支撑面402支撑部分柔性显示屏200,部分柔性显示屏200弯折并脱离第一支撑面401和第二支撑面402,柔性显示屏200的截面形状呈现类似棒球型。
在本实施例中,电子设备1000采用折叠装置100实现屏幕内折,电子设备1000可弯折。折叠装置100的转动机构20的主运动机构为第一支撑件2及第二支撑件3与中壳1之间的单级实体轴转动,零件数量少,零件配合关系简单,机构自由度为1,尺寸链短,累 积误差小,因此转动机构20的主运动机构的控制精度高,从而提高了折叠装置100的转动精度,有利于提高电子设备1000的用户使用体验。
如图16所示,第一壳体10与第二壳体30处于打开状态时,第一支撑件2遮盖中壳1的部分内侧空间12,第二支撑件3遮盖中壳1的部分内侧空间12。此时,第一支撑件2与第二支撑件3彼此靠近,第一支撑件2的支撑面21与第二支撑件3的支撑面31之间的距离较小,转动机构20采用两板式结构即可在打开状态中对柔性显示屏200的折弯部200b提供较为完整的平面支撑。示例性的,折叠装置100处于打开状态时,第一支撑件2与第二支撑件3拼接,以更好地为柔性显示屏200提供强力支撑。
如图17所示,第一壳体10与第二壳体30处于闭合状态时,第一支撑件2部分伸入中壳1的内侧空间12,第二支撑件3部分伸入中壳1的内侧空间12。在本实施例中,折叠装置100处于闭合状态时,第一支撑件2和第二支撑件3部分伸入中壳1的内侧空间12,中壳1的内侧空间12中位于第一支撑件2与第二支撑件3之间的部分空间被释放,形成容屏空间,柔性显示屏200可以部分伸入中壳1的内侧空间12,提高了空间利用率,使得电子设备1000的部件排布更为紧凑,有利于电子设备1000的小型化。
如图16所示,第一壳体10与第二壳体30处于打开状态时,第一支撑件2抵持中壳1的外盖板11的一侧边缘,第二支撑件3抵持外盖板11的另一侧边缘。外盖板11能够在折叠装置100处于打开状态时,对第一支撑件2和第二支撑件3进行止位,以防止折叠装置100在展开时过折,从而降低柔性显示屏200的受力,提高柔性显示屏200和电子设备1000的可靠性。
如图16所示,第一壳体10与第二壳体30处于打开状态时,中壳1位于第一安装槽101和第二安装槽301,第一壳体10及第二壳体30遮盖外盖板11。如图17所示,第一壳体10与第二壳体30处于闭合状态时,中壳1部分伸出第一安装槽101和第二安装槽301,外盖板11相对第一壳体10及第二壳体30露出。在本实施例中,折叠装置100在打开状态与闭合状态切换的过程中,中壳1相对第一壳体10和第二壳体30逐渐露出或逐渐被隐藏,三者相配合能够实现折叠装置100和电子设备1000的背侧自遮蔽,提高了外观完整性和防水、防尘性能。
如图17所示,第一壳体10与第二壳体30处于闭合状态时,第一壳体10的第一挡板105与第二壳体30的第二挡板305拼接,并共同遮挡第一壳体10的第一本体104与第二壳体30的第二本体304之间的缝隙。此时,折叠装置100和电子设备1000实现外观自遮蔽。
请一并参阅图18和图19,图18是图1所示电子设备1000沿D-D处剖面的截面图,图19是图3所示电子设备1000沿E-E处剖开的截面图。
第一同步摆臂51的转动端511、齿轮组53以及第二同步摆臂52的转动端521安装于中壳1的活动空间18。第一同步摆臂51的转动端511转动连接中壳1,第一同步摆臂51的活动端512活动连接第一支撑件2,在第一壳体10与第二壳体30相对折叠和相对展开的过程中,第一同步摆臂51的活动端512相对第一支撑件2滑动且转动。第二同步摆臂52的转动端521转动连接中壳1,第二同步摆臂52的活动端522活动连接第二支撑件3,在第一壳体10与第二壳体30相对折叠和相对展开的过程中,第二同步摆臂52的活动端 522相对第二支撑件3滑动且转动。第二同步摆臂52的转动端521通过齿轮组53啮合第一同步摆臂51的转动端511。
在本实施例中,在折叠装置100展开和折叠的过程中,第一同步摆臂51相对第一支撑件2的滑动和转动动作与第二同步摆臂52相对第二支撑件3的滑动和转动动作对称,从而使得第一支撑件2和第二支撑件3相对中壳1的转动动作保持同步,也即同步相互靠近或相互远离,因此第一壳体10和第二壳体30相对中壳1的转动动作同步性好,提高了折叠装置100和电子设备1000的机构操作体验。
如图18所示,由于第一同步摆臂51的转动端511、齿轮组53以及第二同步摆臂52的转动端521呈弧形排布,充分利用了中壳1的内侧空间12的底部空间,从而将中壳1的内侧空间12的顶部空间释放出来、形成容屏空间,柔性显示屏200能够在闭合状态时,部分收容于中壳1的内侧空间,有利于提高电子设备1000的部件排布的紧凑性,减小电子设备1000的体积。
以上描述,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内;在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。因此,本申请的保护范围应以权利要求的保护范围为准。
