为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。
请参阅图1和图2,图1示出了相关技术中的可折叠的电子设备1在展开态下的主视图,图2示出了图1所示电子设备1在折叠态下的主视图。该电子设备1包括机身01和设置于机身01上的柔性显示屏02。机身01包括折叠机构011、第一侧板012以及第二侧板013,第一侧板012和第二侧板013分别连接于折叠机构011的两侧,并能够基于折叠机构011在展开态与折叠态之间转动。柔性显示屏02设置于第一侧板012和第二侧板013上,以能够随第一侧板012和第二侧板013的转动而折叠或展开。
对比图1和图2可知,在柔性显示屏02处于折叠态时,柔性显示屏02的可柔性形变部位021会发生弯折,折叠机构011会对可柔性形变部位021施加力的作用,可能导致可柔性形变部位021受到拉扯、挤压等,易导致可柔性形变部位021发生拱起、褶皱等缺陷,甚至发生损坏,影响柔性显示屏02在折叠态下的外观及使用寿命,进而影响电子设备1的使用寿命及用户使用体验。
有鉴于此,本申请实施例提供一种折叠组件、包括该折叠组件的折叠装置以及包括该折叠装置的终端设备,能够改善相关技术中柔性显示屏的可柔性形变部位易受折叠机构的力的作用而导致受损的技术问题。
本申请实施例提供的终端设备属于可折叠电子设备,即能够实现折叠和展开的电子设备。该终端设备可以为手机、平板电脑、膝上型电脑(Laptop)、笔记本电脑(Notebook PC)、个人数码助理(Personal Digital Assistant,PDA)、可穿戴设备(例如手表)、车载设备、增强现实(Augmented Reality,AR)/虚拟现实(Virtual Reality,VR)设备等,但不限于此。为便于理解,本申请实施例中,以终端设备为手机作为示例进行介绍说明。
请参阅图3和图4,图3示出了本申请一些实施例提供的终端设备10000在展开态下的结构示意图,图4示出了图3所示终端设备10000在折叠态下的结构示意图。在不同使用需求下,终端设备10000可以展开至展开态,也可以折叠至折叠态,还可以处于展开态与折叠态之间的中间态。应理解,中间态可以是终端设备10000处于展开态与折叠态之间的任意一种状态,而非唯一的状态。
该终端设备10000包括折叠装置1000和折叠屏2000,折叠屏2000设置于折叠装置1000上。其中,折叠装置1000可为折叠屏2000提供支撑和防护,并能够折叠或展开。折叠屏2000即为柔性屏,以能够随折叠装置1000一同折叠或展开。可以理解,折叠屏2000能够用于显示信息并为用户提供交互界面,可以是多种类型的显示屏。
请参阅图5,图5示出了本申请一些实施例提供的折叠装置1000的结构示意图。折叠装置1000包括折叠组件100、第一壳体200以及第二壳体300。折叠组件100位于第一壳体200与第二壳体300之间,并分别连接于第一壳体200和第二壳体300。第一壳体200和第二壳体300可基于折叠组件100发生相对转动,以能够相对靠拢而转动至折叠态,或者相对远离而转动至展开态。
可以理解,折叠组件100的数量可以为一个或多个;在折叠组件100的数量为多个时,各折叠组件100可以依次间隔设置,并均位于第一壳体200与第二壳体300之间。
请继续参阅图3和图5,折叠屏2000设置于第一壳体200和第二壳体300上,能够随第一壳体200和第二壳体300的转动而折叠或展开。折叠屏2000具有可折叠部位2100,可折叠部位2100的位置与折叠组件100的位置相对应,也即可折叠部位2100与折叠组件100相对设置。可折叠部位2100具有柔性,以使得第一壳体200和第二壳体300发生相对转动时,折叠屏2000能够通过可折叠部位2100发生弯折而实现折叠。可以理解,折叠屏2000对应于第一壳体200的部位可以具有柔性,也可以为刚性;折叠屏2000对应于第二壳体300的部位可以具有柔性,也可以为刚性。
示例性地,终端设备10000可以为内折型终端设备,折叠屏2000即为内折型折叠屏。在折叠屏2000折叠后,折叠屏2000的显示面位于内侧。折叠屏2000的背面设置于第一壳体200和第二壳体300上,折叠屏2000的显示面裸露。其中,折叠屏2000的显示面即用于显示图像的一面,折叠屏2000的背面即与显示面相对的另一面。
请参阅图3和图5,在终端设备10000处于展开态时,折叠装置1000和折叠屏2000也均处于展开态,第一壳体200用于安装折叠屏2000的第一面201和第二壳体300 用于安装折叠屏2000的第二面301大致处于同一平面,即第一面201与第二面301之间的夹角大致为180°;此时,折叠屏2000即大致呈平整的展平状态,以使终端设备10000具有较大的显示面积。应理解,在折叠装置1000处于展开态时,并非限定第一面201与第二面301之间的夹角为绝对的180°,两者之间的夹角也可以大于或小于180°,但接近于180°,例如夹角的范围可以为165至190°(例如170°、173°、175°、182°、185°等,但不限于此),也同样能够实现折叠屏2000的展开。
请参阅图4,在终端设备10000处于折叠态时,折叠装置1000和折叠屏2000也均处于折叠态,第一壳体200用于安装折叠屏2000的第一面201和第二壳体300用于安装折叠屏2000的第二面301相对设置并大致平行,即第一面201与第二面301之间的夹角大致为0°;此时,折叠屏2000即相对于可折叠部位2100折叠而呈折叠态,并位于第一壳体200与第二壳体300之间,以利于终端设备10000的收纳,并可降低折叠屏2000受外界伤害的可能性。应理解,在折叠装置1000处于展开态时,并非限定第一面201与第二面301绝对平行,两者之间的夹角也可以大于0°,但接近于0°,例如夹角的范围可以为0°至15(例如1°、2°、3°、5°、10°等,但不限于此),也同样能够实现折叠屏2000的折叠。
可选地,第一壳体200和第二壳体300中的至少一者可以设置有安装空间,以用于安装终端设备10000的电子元器件。例如,电子元器件可以包括电路板、电池、受话器、扬声器、摄像头等,但不限于此。其中,电路板可以集成终端设备10000的主控制器、存储单元、天线模块、电源管理模块等电子元器件,电池则可以为折叠屏2000、电路板、受话器、扬声器、摄像头等电子元器件供电。第一壳体200和第二壳体300的形状及结构可以相同或不同,本申请实施例不作限定。第一壳体200和第二壳体300可以为中框结构。
下面,将对本申请实施例提供的折叠组件100进行介绍说明。
为了方便下文各实施例的描述,建立XYZ三轴直角坐标系,定义折叠组件100的宽度方向为X轴方向,X轴方向即平行于终端设备10000处于展开态时第一壳体200指向第二壳体300的方向;定义折叠组件100的长度方向为Y轴方向,Y轴方向即平行于终端设备10000处于展开态时第一壳体200的一侧边沿指向相对的另一侧边沿的方向;定义折叠组件100的厚度方向为Z轴方向,Z轴方向即平行于终端设备10000处于展开态时第一壳体200指向折叠屏2000的方向,也即平行于终端设备10000的厚度方向。X轴方向、Y轴方向和Z轴方向两两相互垂直。X轴方向包括X轴正向和X轴负向,Y轴方向和Z轴方向同理。应理解,折叠组件100的坐标系可以根据实际需要灵活设置,本申请仅给出了一种示例,并不能认为是对本申请构成的特殊限制。
请参阅图6至图9,图6示出了本申请一些实施例提供的折叠组件100在展开态下的立体结构示意图,图7示出了图6所示折叠组件100在展开态下的主视图,图8示出了图6所示折叠组件100折叠至折叠态时与折叠屏2000的可折叠部位2100相配合的主视图,图9示出了图6所示折叠组件100的爆炸图。折叠组件100包括底座10、第一固定件21、第二固定件22、第一主摆臂31、第二主摆臂32、第一支撑件41以及第二支撑件42,其中:
底座10可对第一主摆臂31及第二主摆臂32起到支撑和连接的作用,可以是各种 形状规则或不规则的结构,例如块状结构、架体结构、壳体结构、板体结构等,但不限于此。底座10可以是单个部件,也可以包括多个相装配的部件。在一些情形下,底座10也被称为主轴、主体等。
第一固定件21和第二固定件22分别位于底座10的两侧。应理解,底座10的两侧是指以底座10的中心纵截面m为分界面的两侧,中心纵截面m即为平行于底座10的长度方向(即Y轴方向)和厚度方向(即Z轴方向)并沿底座10的宽度方向(即X轴方向)平分底座10的平面。第一固定件21与第二固定件22可以相对设置,也即沿底座10的长度方向处于同一位置;当然,在一些情况下,第一固定件21与第二固定件22也可以不相对设置,也即沿底座10的长度方向相错开。
第一固定件21用于与第一壳体200固定连接,第二固定件22用于与第二壳体300固定连接;在第一壳体200和第二壳体300相对转动时,即分别带动第一固定件21和第二固定件22转动。可以理解,第一固定件21与第一壳体200可以分体成型而相连接,例如可通过紧固件(例如螺栓、螺钉、销钉、铆钉等)相连接,当然,在其他一些情况下,第一固定件21与第一壳体200也可以为一体成型的一体式结构;类似地,第二固定件22与第二壳体300可以分体成型而相连接,也可以为一体成型的一体式结构。可以理解,第一固定件21和第二固定件22可以是各种形状规则或不规则的结构件,例如块状结构、板状结构等,但不限于此。
第一主摆臂31与底座10转动连接,且第一主摆臂31与第一固定件21转动连接;第一固定件21即通过第一主摆臂31与底座10转动连接。第一主摆臂31与底座10和第一固定件21转动连接的方式可以相同或不同。第二主摆臂32与底座10转动连接,且第二主摆臂32与第二固定件22转动连接;第二固定件22即通过第二主摆臂32与底座10转动连接。第二主摆臂32与底座10和第二固定件22转动连接的方式可以相同或不同。可以理解,第一主摆臂31和第二主摆臂32可以是各种形状的摆臂结构,第一主摆臂31和第二主摆臂32的形状及结构可以相同或不同,本申请实施例中不作限定。
可选地,可以是第一主摆臂31的相对两端分别与底座10和第一固定件21转动连接,当然,第一主摆臂31不限于通过其端部的部分与底座10或第一固定件21转动连接,也可以通过其他部位与底座10或第一固定件21转动连接;类似地,可以是第二主摆臂32的相对两端分别与底座10和第二固定件22转动连接,当然,第二主摆臂32不限于通过其端部的部分与底座10或第二固定件22转动连接。
第一支撑件41与第一固定件21转动连接,且第一支撑件41与第一主摆臂31滑动连接及转动连接,以使第一支撑件41与第一主摆臂31能够发生相对滑动及转动。第一支撑件41包括第一支撑面410,第一支撑面410用于支撑折叠屏2000的可折叠部位2100。第二支撑件42与第二固定件22转动连接,且第二支撑件42与第二主摆臂32滑动连接及转动连接,以使第二支撑件42与第二主摆臂32能够发生相对滑动及转动。第二支撑件42包括第二支撑面420,第二支撑面420用于支撑折叠屏2000的可折叠部位2100。可以理解,第一支撑件41和第二支撑件42可以是多种形状的结构,例如可以为板状结构或片状结构,以利于形成具有一定面积的第一支撑面410和第二支撑面420,可更好地支撑可折叠部位2100;当然,在其他一些情况下,第一支撑件 41和第二支撑件42也可以是块状结构等其他形状的结构。
第一固定件21和第二固定件22能够基于底座10相对转动,以使折叠组件100在展开态与折叠态之间切换。在折叠组件100由展开态朝折叠态切换时,也即第一固定件21和第二固定件22相对靠拢转动或相向转动时,第一固定件21带动第一主摆臂31和第一支撑件41相对于底座10转动,该过程中,第一主摆臂31相对于第一固定件21转动,且第一主摆臂31与第一支撑件41相对滑动及转动,也即第一主摆臂31相对于第一固定件21转动的同时,驱动第一支撑件41相对于第一主摆臂31滑动及转动(由于第一支撑件41与第一固定件21转动连接,因此第一支撑件41相对于第一主摆臂31滑动及转动时不易卡滞);第二固定件22带动第二主摆臂32和第二支撑件42相对于底座10转动,该过程中,第二主摆臂32相对于第二固定件22转动,且第二主摆臂32与第一支撑件41相对滑动及转动,也即第二主摆臂32相对于第二固定件22转动的同时,驱动第二支撑件42相对于第二主摆臂32滑动及转动(由于第二支撑件42与第二固定件22转动连接,因此第二支撑件42相对于第二主摆臂32滑动及转动时不易卡滞),以使折叠组件100处于折叠态时,第一支撑面410与第二支撑面420相对设置并形成有夹角a(夹角a即大于0°且小于180°,例如可以是锐角、直角或钝角),且第一支撑面410靠近底座10的边沿与第二支撑面420靠近底座10的边沿之间的距离为第一距离L1,第一支撑面410远离底座10的边沿与第二支撑面420远离底座10的边沿之间的距离为第二距离L2,第一距离L1大于第二距离L2,例如图8所示。
根据以上描述可知,本申请实施例提供的折叠组件100,由于在第一固定件21和第二固定件22基于底座10相对转动而使折叠组件100由展开态朝折叠态切换时,第一主摆臂31相对于第一固定件21转动并与第一支撑件41相对滑动及转动,第二主摆臂32相对于第二固定件22转动并与第一支撑件41相对滑动及转动,使得折叠组件100处于折叠态时,第一支撑面410与第二支撑面420相对设置并形成有夹角a,且第一支撑面410与第二支撑面420靠近底座10的边沿之间的第一距离L1大于远离底座10的边沿之间的第二距离L2,因此第一支撑面410与第二支撑面420之间即可形成靠近底座10的一侧大于远离底座10的一侧的空间,可容纳折叠屏2000的可折叠部位2100,利于可折叠部位2100可大致呈水滴形而无需完全对折,可有效降低折叠屏2000的可折叠部位2100因折叠形变程度过大而导致损坏的可能性,利于提高折叠屏2000处于折叠态的外观,并利于提高折叠屏2000和终端设备10000的使用寿命。
另外,由于第一主摆臂31与第一支撑件41滑动连接及转动连接,也即通过第一主摆臂31驱动第一支撑件41活动,且第二主摆臂32与第二支撑件42滑动连接及转动连接,也即通过第二主摆臂32驱动第二支撑件42活动,相比于通过与底座10转动连接且与第一固定件21滑动连接的第一副摆臂驱动第一支撑件41活动、以及相比于通过与底座10转动连接且与第二固定件22滑动连接的第二副摆臂驱动第二支撑件42活动而言,利于减小第一支撑件41与第一主摆臂31相对滑动的行程、以及减小第二支撑件42与第二主摆臂32相对滑动的行程,进而利于提高结构紧凑度,减小尺寸,从而利于折叠组件100的小型化和轻薄化。
在一些实施例中,请参阅图7和图8,在折叠组件100由折叠态朝展开态切换时, 也即第一固定件21和第二固定件22相对远离转动或相背转动时,第一固定件21带动第一主摆臂31和第一支撑件41相对于底座10转动,该过程中,第一主摆臂31相对于第一固定件21转动,且第一主摆臂31与第一支撑件41相对滑动及转动,也即第一主摆臂31相对于第一固定件21转动的同时,驱动第一支撑件41相对于第一主摆臂31滑动及转动;第二固定件22带动第二主摆臂32和第二支撑件42相对于底座10转动,该过程中,第二主摆臂32相对于第二固定件22转动,且第二主摆臂32与第一支撑件41相对滑动及转动,也即第二主摆臂32相对于第二固定件22转动的同时,驱动第二支撑件42相对于第二主摆臂32滑动及转动,以使折叠组件100处于展开态时,第一支撑面410与第二支撑面420相齐平,也即大致共面,但应允许存在公差,例如第一支撑面410与第二支撑面420之间的高度差可以是0mm至5mm,第一支撑面410与第二支撑面420之间的夹角可以是0°至12°(例如1°、2°、3°、5°、10°等,但不限于此)。这样,利于折叠组件100处于展开态时,提高折叠屏2000的可折叠部位2100支撑于第一支撑面410和第二支撑面420上时的平整度,不易发生凹陷或褶皱,可提高显示效果。
下面对第一主摆臂31和第二主摆臂32与底座10转动连接的方式进行介绍。

可选地,在一些实施例中,请参阅图9,沿底座10的长度方向(即Y轴方向),第一主摆臂31和第二主摆臂32依次设置,也即第一主摆臂31和第二主摆臂32相错开,而非处于同一位置。这样,利于减小折叠组件100沿底座10的宽度方向(即X轴方向)的宽度。
当然,在其他一些实施例中,沿底座10的长度方向(即Y轴方向),第一主摆臂31和第二主摆臂32也可以处于同一位置,即大致对称设置。

可选地,第一主摆臂31与底座10转动连接的旋转轴线和第一副摆臂51与底座10转动连接的旋转轴线不重合;这样,在第一固定件21带动第一主摆臂31与第一副摆臂51转动时,第一副摆臂51与第一固定件21之间即会发生相对滑动。类似地,第二主摆臂32与底座10转动连接的旋转轴线和第二副摆臂52与底座10转动连接的旋转轴线不重合;这样,在第二固定件22带动第二主摆臂32与第二副摆臂52转动时,第二副摆臂52与第二固定件22之间即会发生相对滑动。

可选地,在一些实施例中,请参阅图9,折叠组件100还可以包括第一齿轮91和第二齿轮92。第一齿轮91固定于第一副摆臂51上,第一齿轮91可以直接或间接固定于第一副摆臂51上;在一些情况下,第一齿轮91与第一副摆臂51可以为一体成型的一体式结构。第二齿轮92可以固定于第二副摆臂52上,第二齿轮92可以直接或间接固定于第二副摆臂52上;在一些情况下,第二齿轮92与第二副摆臂52可以为一体成型的一体式结构。第一齿轮91与第二齿轮92啮合传动,以使得第一副摆臂51与第二副摆臂52相对转动时可以通过第一齿轮91与第二齿轮92啮合传动,可以提高第一固定件21与第二固定件22相对转动的同步性。
可选地,请参阅图9,折叠组件100还可以包括第三齿轮93和第四齿轮94,第三齿轮93和第四齿轮94可以分别通过一转轴结构可转动地设置于底座10上。第三齿轮93和第四齿轮94相啮合,且第三齿轮93与第一齿轮91相啮合,第四齿轮94与第二齿轮92相啮合。这样,在第一副摆臂51与第二副摆臂52相对转动时,第一副摆臂51带动第一齿轮91旋转,第一齿轮91即可通过第三齿轮93和第四齿轮94啮合传动第二齿轮92,以使第一固定件21与第二固定件22同步转动,且转动方向相反。

在一些情况下,请参阅图16,在折叠组件100处于展开态时,第一滑动体3111可以位于第一轨迹槽4111的第一端4111a,第二滑动体3211可以位于第二轨迹槽4211的第三端4211a。在折叠组件100处于折叠态时,请参阅图18,第一滑动体3111可以位于第一轨迹槽4111的第二端4111b,第二滑动体3211可以位于第二轨迹槽4211的第四端4211b。第二端4111b可以为第一轨迹槽4111远离第一端4111a的另一端,第四端4211b可以为第二轨迹槽4211远离第三端4211a的另一端。

可选地,在一些实施例中,请参阅图14,以及图16至图18,第一轨迹槽4111包括第一滑槽41111和第二滑槽41112,第二滑槽41112位于第一滑槽41111的一侧并与第一滑槽41111相连通,因此第一滑槽41111和第二滑槽41112组合形成的形状为非圆弧形和非直线形,也即不规则的形状,例如可以是弯折形。在折叠组件100处于展开态时,第一滑动体3111位于第一滑槽41111内,例如图16所示。在折叠组件100处于折叠态时,第一滑动体3111位于第二滑槽41112内,例如图18所示。
类似地,请参阅图15,以及图16至图18,第二轨迹槽4211包括第三滑槽42111和第四滑槽42112,第四滑槽42112位于第三滑槽42111的一侧并与第三滑槽42111 相连通,因此第三滑槽42111和第四滑槽42112组合形成的形状为非圆弧形和非直线形,也即不规则的形状,例如可以是弯折形。在折叠组件100处于展开态时,第二滑动体3211位于第三滑槽42111内。在折叠组件100处于折叠态时,第二滑动体3211位于第四滑槽42112内。
如此设置,由于第二滑槽41112位于第一滑槽41111的一侧,第二滑槽41112和第一滑槽41111即组合形成非圆弧形槽和非直线形槽,因此在第一支撑件41与第一主摆臂31相对滑动和转动时,能够更好地适配第一滑动体3111的运动轨迹,而不限制第一滑动体3111始终沿圆弧形或直线形的轨迹在第一轨迹槽4111中滑动,即允许第一滑动体3111在第一轨迹槽4111中拐弯或转弯,利于第一支撑件41与第一主摆臂31能够相对匀速运动;由于第四滑槽42112位于第三滑槽42111的一侧,第四滑槽42112和第三滑槽42111即组合形成非圆弧形槽和非直线形槽,因此在第二支撑件42与第二主摆臂32相对滑动和转动时,能够更好地适配第二滑动体3211的运动轨迹,而不限制第二滑动体3211始终沿圆弧形或直线形的轨迹在第二轨迹槽4211中滑动,即允许第二滑动体3211在第二轨迹槽4211中拐弯或转弯,利于第二支撑件42与第二主摆臂32能够相对匀速运动;进而可提高第一支撑件41和第二支撑件42对折叠屏2000的可折叠部位2100施加力时的均匀性,减小折叠屏2000因受力不均匀而出现褶皱或挤压拱起的问题的可能性。
而如果将第一轨迹槽4111和第二轨迹槽4211设置为圆弧形或直线形,则在第一支撑件41与第一主摆臂31相对滑动和转动时,第一滑动体3111须始终沿圆弧形或直线形的轨迹在第一轨迹槽4111中滑动,以及在第二支撑件42与第二主摆臂32相对滑动和转动时,第二滑动体3211须始终沿圆弧形或直线形的轨迹在第二轨迹槽4211中滑动,导致运动过程中,第一支撑件41与第一主摆臂31之间的相对运动速度会发生变化,第二支撑件42与第二主摆臂32之间的相对运动速度会发生变化,因此第一支撑件41和第二支撑件42在运动过程中转动角度可能会突然发生变化,进而导致第一支撑件41和第二支撑件42对折叠屏2000的可折叠部位2100施加的力会出现突然变化而不均匀,可能会导致折叠屏2000因受力不均匀而出现褶皱或挤压拱起的问题。而本申请实施例中上述的技术方案则能够较好地改善该问题。

可选地,在一些实施例中,请参阅图18,在折叠组件100处于折叠态时,第六支撑面710与第七支撑面720形成有夹角d(夹角d即大于0°且小于180°,例如可以是锐角、直角或钝角),且第六支撑面710远离第一支撑件41的边沿与第七支撑面720远离第二支撑件42的边沿之间的距离为第三距离L3,第六支撑面710靠近第一支撑件41的边沿与第七支撑面720靠近第二支撑件42的边沿之间的距离为第四距离L4,第三距离L3大于第四距离L4。
