技术领域
本申请涉及终端设备领域,尤其涉及一种折叠屏设备。
背景技术
随着人们生活水平的不断提高,手机等移动终端的屏幕显示效果越来越得到重视,然而,手机的体积制约了屏幕尺寸的扩大。
目前,为了在较小的手机上实现较大的屏幕面积,手机可以采用折叠式结构。具体的,手机一般可以具有可以绕转轴相对旋转并折叠的两个主体,而屏幕的柔性屏体同时覆盖于手机的这两个主体表面。两个主体绕中间的转轴旋转至位于同一平面时,屏幕呈展开状态,并具有较大的显示面积;两个主体绕转轴旋转至相对折叠时,手机呈较小的体积和尺寸。两个主体内设置有电路板等电子器件,且通过跨越转轴两侧的柔性电连接线实现不同主体内电子器件的电性连接。
然而,为了适应手机的折叠和展开状态,柔性电连接线需要有一定的冗余长度,且随手机每次开合而呈不同的弯曲状态,这样柔性电连接线容易断裂或者与其它结构发生剐蹭,可靠性较差。
发明内容
本申请提供一种折叠屏设备,具有较高的电连接可靠性。
第一方面,本申请提供一种折叠屏设备,包括两个框体、与两个框体铰接的转轴组件以及电连接线,两个框体并可绕转轴组件的转轴转动以合上或打开;转轴组件包括连接结构和铰链,铰链连接在连接结构和框体之间,连接结构具有贯通转轴组件相对两侧的通道,电连接线的两端分别与两个框体连接,且电连接线穿设于通道内,通道和铰链分别位于转轴组件的轴向上的不同位置。这样电连接线得到了转轴组件的定位,在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。
在一种可选的实施方式中,连接结构位于转轴组件沿轴向的中部区域。这样连接结构所处的区域可形成一个静态容置空间,被连接结构所定位的电连接线可以穿过并收容于该区域内,而不会受到转轴等结构在转动时的干扰。
在一种可选的实施方式中,连接结构包括第一轴盖和第二轴盖,第一轴盖和第二轴盖相对设置,且第一轴盖位于转轴组件的靠近框体铰接端的一侧,第二轴盖位于转轴组件的靠近框体自由端的一侧;第一轴盖和第二轴盖围成可容置转轴的空间。这样通过第一轴盖和第二轴盖共同形成容纳空间,并将电连接线收容在该容纳空间内部,电连接线得到了第一轴盖和第二轴盖的遮挡和保护,结构可靠性较高,且美观性较好。
在一种可选的实施方式中,连接结构还包括定位件,定位件位于第一轴盖和第二轴盖共同围成的空间内;通道由第一轴盖和第二轴盖中的一者与定位件共同形成。
这样定位件和第一轴盖或者第二轴盖共同形成了位于电连接线中段的一个定位点,电连接线的中段和端部位置均得到了定位,因而电连接线的能够自由弯折的部分长度变短,相应的,弯折变形幅度也得以减小;同时,整个电连接线在长度方向上分为长度接近的两段,这两段电连接线的弯折变形量也较为相近,且所产生的形变和位移较为同步;得到转轴组件的辅助定位的电连接线,其在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。
在一种可选的实施方式中,定位件和第一轴盖共同围成通道。
在一种可选的实施方式中,折叠屏设备中还包括第一磁性件与第二磁性件,第一磁性件设置在第一轴盖上,第二磁性件设置在定位件上;第一磁性件和第二磁性件可相互吸附,以使定位件和第一轴盖相互定位。这样通过磁性件的磁力作用,可以在转轴组件的装配过程中,预先将电连接线设置在装配组件上,避免电连接线因外界拉扯或者是其它作用力而脱离装配位置,有效减小了装配难度;同时,磁性件的吸附作用,也能够让第一轴盖和定位件之间压紧,或者使电连接线贴合在第一轴盖上,从而对电连接线进行辅助定位。
在一种可选的实施方式中,第一磁性件和第二磁性件均为磁铁。
在一种可选的实施方式中,第一磁性件和第二磁性件中的一者为磁铁,另一者为软磁体。这样第一磁性件和第二磁性件的设置方式较为自由,结构较为简单。
在一种可选的实施方式中,定位件包括第一定位部,第一定位部位于定位件的面向第一轴盖的一侧,且第一定位部的顶端凸出于定位件的其它部分的外侧,并与第一轴盖抵接。这样第一定位部可以和第一轴盖连接,从而让定位件和第一轴盖具有固定的相对位置。
在一种可选的实施方式中,第一定位部为至少两个,且分布于定位件的沿转轴轴向的相对两侧,位于定位件长度方向相对两侧的第一定位部之间具有可供电连接线通过的间距。这样多个第一定位部能够让定位件的不同部位均与第一轴盖之间保持间距。
在一种可选的实施方式中,定位件还包括第二定位部,第二定位部位于定位件的面向第二轴盖的一侧,并与第二轴盖连接。这样第二定位部能够使定位件和第二轴盖之间具有固定的相对位置。
在一种可选的实施方式中,电连接线包括柔性电路板。柔性电路板中包括有多根引线,从而可实现多个不同电信号的传输。
在一种可选的实施方式中,第一轴盖具有面向定位件的第一固定面,定位件具有面向第一轴盖的第二固定面,第一固定面和第二固定面相对设置以形成通道,柔性电路板被夹设在第一固定面和第二固定面之间。这样第二固定面和第一轴盖之间形成上述用于穿设柔性电路板的间隙,能够将在于柔性电路板的板面垂直的方向上对柔性电路板进行定位,使柔性电路板被定位件与第一轴盖所夹持,而无法随框体的转动而产生大幅的弯曲和变形。
在一种可选的实施方式中,第一固定面和第二固定面均为凹凸表面,且凹凸表面的凹凸方向朝向柔性电路板的厚度方向。此时,定位件和第一轴盖之间会形成一具有凹凸形状的通道,而穿过该通道的柔性电路板也会形成相应的凹凸形状,这样柔性电路板会和凹凸起伏的通道壁接触,并被通道壁所阻碍,避免柔性电路板在自身长度方向上出现前后移动。
在一种可选的方式中,电连接线还包括线缆,柔性电路板和线缆间隔且并排设置。线 缆可以用于传输同轴信号等不同信号,且线缆和柔性电路板相对独立设置,不会发生干涉或者相互影响。
在一种可选的方式中,定位件的第二固定面上开设有导向槽,导向槽贯穿定位件宽度方向的相对两侧,且导向槽的槽口朝向第一轴盖;线缆穿设在导向槽内。线缆的处于定位件与第一轴盖之间的线缆段,可以部分处于或者全部埋设于导向槽内部,并由此得以定位。
在一种可选的实施方式中,线缆具有轴向定位凸起;导向槽内具有凹陷部,轴向定位凸起卡设在凹陷部内,以将线缆固定在导向槽中。这样线缆设置在导向槽中时,线缆的轴向定位凸起会位于凹陷部之内,凹陷部的侧壁即可限制线缆沿长度方向的位移。
在一种可选的实施方式中,导向槽还开设有避让缺口,避让缺口的形状和轴向定位凸起的形状相匹配。这样线缆可以通过避让缺口而使具有轴向定位凸起的线缆进入导向槽内,并得到导向槽的定位。
在一种可选的实施方式中,导向槽具有多个依次连接的弯折段,弯折段的弯折方向朝向线缆的径向,且相邻两个弯折段的弯折方向不同。这些弯折段会将线缆的多个不同的线缆段分别导向不同的方向,导向槽对线缆会产生较大的阻力,阻止线缆沿长度方向相对于线槽滑动。
在一种可选的实施方式中,柔性电路板的端部设置有补强钢片,补强钢片固定于框体上,且补强钢片和框体之间设置有弹性缓冲垫。这样能够利用补强钢片将柔性电路板的端部连接至框体,同时,由于弹性缓冲垫自身具有一定的可变形能力,所以补强钢片和对应的框体之间会形成一定的间隙,能通过弹性缓冲垫的弹性变形,而对柔性电路板的端部与框体之间连接点位置存在的小幅的位置误差进行补偿,避免柔性电路板因长度不足而出现绷紧甚至是断裂的风险。
在一种可选的实施方式中,框体上开设有线槽,线缆的端部设置在线槽内,补强钢片盖设在线槽的槽口外侧,以将线缆的端部固定在线槽内。这样能够将线缆的端部连接至框体。
在一种可选的实施方式中,折叠屏设备还包括柔性防护罩,柔性防护罩的相对两侧边缘分别和两个框体连接,柔性防护罩覆盖于电连接线的朝向框体自由端的一侧。在折叠屏设备开合时,柔性防护罩会阻挡在电连接线和外侧的结构之间,避免外侧其它结构接触到电连接线。
在一种可选的实施方式中,柔性防护罩具有波纹状罩体。此时,柔性防护罩整体具有凹凸起伏的波纹形面,波纹形面可以在折叠屏设备开合时,相应进行展开或折叠,从而形成不同大小的防护区域,以适应于折叠屏设备的不同开合角度。
在一种可选的实施方式中,柔性防护罩由导热材料构成。这样连接在不同框体之间的柔性防护罩,可以将框体上的热量传递至另一框体,使两个框体的温度较为均匀。而柔性屏体的对应设置在不同框体上的各个部位之间的温度差异较小,具有较好的显示均匀性。
在一种可选的实施方式中,柔性防护罩具有和框体的表面贴合的散热面。散热面具有较大的散热面积,因而柔性防护罩可以利用散热面和框体实现较快的热传导速度,从而令第一框体和第二框体之间具有较好的温度均匀性。
本申请的折叠屏设备包括第一框体、第二框体和连接在第一框体和第二框体之间的转轴组件,转轴组件中的连接结构形成能够穿设及固定电连接线的通道。这样电连接线得到 了转轴组件的定位,因而电连接线的能够自由弯折的部分长度变短,相应的,弯折变形幅度也得以减小;同时,整个电连接线在长度方向上分为长度接近的两段,这两段电连接线的弯折变形量也较为相近,且所产生的形变和位移较为同步;得到转轴组件的辅助定位的电连接线,其在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。

具体实施方式
在对本申请实施例进行描述前,为便于理解本申请的技术方案,先对本申请实施例中涉及到的基本概念和术语进行解释说明:
随着柔性屏幕的出现,手机等终端设备可以利用柔性屏幕实现屏幕的弯曲和折叠,从而在让终端设备具有较为紧凑的体积的同时,使柔性屏幕具有较大的显示面积。相应的,终端设备可以为折叠屏设备或者是弯曲屏设备。
图1是本申请实施例提供的一种折叠屏设备的结构示意图。图2a是图1中的折叠屏设备在展开时的结构示意图。图2b是图1中的折叠屏设备在合上后的结构示意图。如图1、图2a和图2b所示,一种折叠屏设备100包括有两个框体以及设置在这些框体上的柔性屏幕200。相邻两个框体的靠近转轴的端部可以绕着位于两个框体之间的转轴进行旋转,从而令两个框体的远离转轴的一端相对靠近或者相对远离,折叠屏设备100即可相应呈现合上或者展开等不同状态。而柔性屏幕200覆盖在框体表面,并可以随着相邻框体之间的位置变化而相应呈现折叠或者展开等状态。具体的,折叠屏设备100包括有第一框体1和第二框体2,第一框体1和第二框体2展开时,两者会相互并列且共面设置。相应的,覆盖在框体表面的柔性屏幕200展开后,即可形成较大的显示表面,该显示表面可以作为一单独的显示屏幕进行显示,如如图2a所示。需要说明的是,折叠屏设备100的框体的数量可以为两个或两个以上,且框体的数量为两个以上时,各相邻框体可以绕着相互平行的转轴转动,从而形成多层折叠结构,或者展开得到更大的显示面积。本申请中,主要以折叠屏设备100中具有两个框体为例进行说明。
其中,本领域技术人员可以理解的是,位于相邻两个框体之间的转轴可以为实体转轴,也可以为虚拟转轴。当该转轴为虚拟转轴时,转轴并不完全由折叠屏设备的实体部件构成,而是为通过折叠屏设备中不同部件在相对移动时的形状约束和位移约束,而形成的虚拟旋转线条。折叠屏设备的相邻两个框体在相对移动时,会绕着该虚拟转轴而相对旋转。
折叠屏设备内部的各部件,例如是主电路板、处理器、存储器以及摄像头组件等,可以分别固定至第一框体1或者是第二框体2上。示例性的,可以将主电路板、处理器以及存储器等部件设置在第一框体1内部,而第二框体2可以用于承载摄像头组件以及天线等部件。此时,为了让位于不同框体的部件之间形成电连接,在折叠屏设备中还设置有电连接线,电连接线的两端分别连接至相邻的两个不同框体的电连接点,从而与各框体上的主电路板、处理器、摄像头组件或者是天线等不同部件连接并传输电信号,而电连接线自身为柔性材质,可以随着框体相对位置的变化而产生相应的弯曲或形变。这样在折叠屏设备呈合上或展开等不同状态时,电连接线仍然能够依靠自身的弯曲变形,而维持相邻两个框体之间的电性连接。
具体的,电连接线可以有多种不同的结构及形式。其中,折叠屏设备中的主电路板可以位于其中一个框体之中,且主电路板会和其它多个部件之间传输电信号;而为了实现主电路板与位于其它框体的部件之间的电性连接,电连接线中包括有柔性电路板(FPC)。柔性电路板可以包括有多根引线,从而可实现多个不同电信号的传输。此外,折叠屏设备中的天线等部件,可以利用同轴线缆和主电路板保持电性连接。因此,在一种可选的方式中,电连接线中也可以包括有呈单根独立设置的线缆,线缆可以用于实现两个单独部件之间的信号传输。本实施例中,单根线缆可以用于传输同轴信号等不同信号。
然而,为了实现柔性屏幕的折叠或展开,折叠屏设备需要有较大的展开及折叠角度,例如是图1中的折叠屏设备中,折叠屏设备的两个框体所形成的角度可以在0°到180°之间变化,相应的,电连接线的两端之间的间距也会在较大范围内变化。因此,在柔性屏幕折叠时,电连接线需要预留较长的冗余长度,才能在柔性屏体展开时,适应两个框体上电连接点之间的间距。而电连接线的冗余长度过长时,电连接线会在两个框体之间的区域内呈大角度弯曲状态,才能正常收容在两个框体之间,且折叠屏设备每一次开合后,电连接线可能会呈不同的弯曲状态。一方面,每次折叠屏设备开合时,电连接线都会在大角度弯曲状态和伸展状态之间切换,电连接线自身容易因材料疲劳而产生断裂、失效等现象;另一方面,电连接线在框体之间呈大角度弯曲时,电连接线容易和折叠屏设备的其它内部部件发生摩擦或剐蹭,对电连接线表面形成损伤。
为此,本申请提供一种折叠屏设备,能够通过框体的相对转动而实现屏幕的折叠或展开,且用于维持相邻框体之间电连接的电连接线具有较高的可靠性,不易发生断裂或磨损。以下分别以不同的场景为例,对折叠屏设备的具体结构进行介绍。
场景一
图3是图1中的折叠屏设备的主要部件的分解示意图。如图3所示,折叠屏设备的物理折叠结构主要包括第一框体1、第二框体2以及连接于第一框体1和第二框体2之间的转轴组件3。其中,两个框体和转轴组件3连接的一端作为铰接端,而框体的远离转轴组件3的一端则作为自由端。两个框体的自由端可以绕转轴组件3旋转,使折叠屏设备整体结构呈打开或合上的状态。
具体的,图4是本申请提供的折叠屏设备中转轴组件的分解示意图。图4所示的转轴组件中,包括有连接结构31和连接在连接结构31上的两个铰链32,每个铰链32中包括两个并列设置的转轴321以及对应连接至各转轴321上的多个铰接臂322。铰接臂322的 一端和转轴铰接,而铰接臂322的另一端用于固定连接至对应的框体上,在铰接臂322的连接带动下,第一框体1和第二框体2可以分别绕各自对应转轴321转动。这样两个转轴321平行设置,而不同框体分别对应连接至不同转轴321,可以让折叠屏设备的两个框体达到较大的折叠以及展开角度。
为了实现铰链32和连接结构31之间的连接和定位,铰链32中还包括有支撑架323,支撑架323支撑在连接结构31和转轴321之间,且转轴321能够相对于支撑架323自由转动。示例性的,支撑架323可以为支撑肋的形式。此外,转轴组件3的整体结构还可以具有多种不同的形状和类型,其具体形状可以参照本领域技术人员常用的转轴支撑结构,此处不再赘述。
图5a是图1中的折叠屏设备在打开状态时转轴组件的位置示意图。图5b是图1中的折叠设备在合上状态时转轴组件的位置示意图。如图5a和图5b所示,可以容易的看出,转轴组件3在连接第一框体1和第二框体2,并进行合上或打开操作时,第一框体1和第二框体2会分别绕转轴组件3内部的两个转轴321转动,而转轴组件3的整体结构并不会发生折叠或者其它变形,也就是说,转轴组件3整体仅发生姿态变化,而自身不会产生折叠等变形情况,转轴组件3内部除转轴321以外的部件也不会产生相对旋转或其它相对位移。因此,转轴组件3可以作为一个整体,利用转轴组件3内部的结构对电连接线4或者其它部件进行辅助定位和固定。
其中,转轴组件3中的两个铰链32可以分别位于连接结构31的两端,而连接结构31的中部区域并未设置转轴321或者其它可转动的部件,因此,连接结构31的中部区域即可形成一个静态容置空间,被转轴组件3所固定的部件可以穿过并收容于连接结构31的中部区域内,而不会受到转轴321等结构在转动时的干扰。本领域技术人员可以理解的是,连接结构31所形成的静态容置空间也可以位于连接结构31的其它位置,例如是连接结构31的端部区域等。以下主要以转轴组件3中连接结构31的中部区域与其它部件之间的连接关系为例进行说明,如无特殊说明,均略去转轴组件3中的铰接臂等无关结构。
图6是本申请实施例提供的折叠屏设备中转轴组件和电连接线的连接示意图。如图6所示,为了让位于不同框体上的主电路板或者柔性屏幕之间实现电性连接,电连接线4会穿过连接在两个框体之间的转轴组件3,具体的,电连接线4会穿过转轴组件3中连接结构31的中部区域,且电连接线4的两端分别连接并耦合至不同框体的电连接点,从而和位于不同框体上的主电路板、处理器或者是其它器件实现导通和信号传输。由前述可知,电连接线4的收容于连接结构31内部的部分,不会受到转轴321转动的干扰。
然而,为了适配于折叠屏设备的展开或折叠,电连接线4会具有较长的冗余长度。折叠屏设备在打开或合上时,第一框体1和第二框体2会转动,相对位置和电连接点的相对距离也随之发生变化。而为了避免过长的电连接线4在框体转动时产生大幅度变形和位置变化,在转轴组件3的连接结构31上可以设置用于定位电连接线4的定位部件。
图7至图16中,对连接结构31和电连接线4的具体连接关系进行进一步详细说明。
图7是本申请实施例提供的折叠屏设备中连接结构在第一方向的结构示意图。图8是图7中的连接结构的分解示意图。图9是本申请实施例提供的折叠屏设备中连接结构在第二方向的结构示意图。图10是图9中的连接结构的分解示意图。在图7至图10中,首先对转轴组件3中连接结构31的大致结构进行介绍。具体如图7至图10所示,转轴组件3 中的连接结构31具体可以包括第一轴盖311、第二轴盖313和定位件312等组成部分。第一轴盖311和第二轴盖313均靠近框体的铰接端,且被夹在两个框体之间。第一轴盖311和第二轴盖313会直接连接或者通过其它部件间接的连接在一起,且第一轴盖311和第二轴盖313会相对固定。第一轴盖311和第二轴盖313的相对两侧均会分别和两个框体连接。其中,第一方向和第二方向为相对的两个方向,例如是第一方向为转轴组件3的由内向外方向,而第二方向为转轴组件3的由外向内方向。
由上述可知,转轴组件3中的第一轴盖311和第二轴盖313具有确定的相对位置,因此可以利用第一轴盖311和第二轴盖313共同实现对定位件312的安装和固定。
具体的,第一轴盖311和第二轴盖313均可以为薄壳状或者薄板状构件,且两者可以近似相互平行设置。示例性的,本实施例中,第一轴盖311和第二轴盖313均为板状件,且第一轴盖311和第二轴盖313的板面延伸方向和转轴321保持平行或者是近似平行。第一轴盖311和第二轴盖313的板面可以延伸至大致与框体等宽的长度,这样第一轴盖311和第二轴盖313可以作为转轴组件3中定位结构的主要构件,以在整个转轴321长度方向上对转轴组件3的其它结构进行支撑,或者是作为转轴组件3的外观件,以遮挡折叠屏设备在折叠变形时,两个相邻框体之间相对旋转时所形成的缝隙。
其中,第二轴盖313可以设置在转轴组件3的外侧,也就是临近框体铰接端的一侧;而第一轴盖311可以设置在转轴组件3的内侧,也就是第二轴盖313的朝向框体的自由端的一侧。此时,第一轴盖311会隐藏在转轴组件3的内部,而第二轴盖313在折叠屏设备的框体旋转时,会暴露于框体的铰接端外侧,从而构成转轴组件3的外观件。相应的,第二轴盖313作为外观件时,第二轴盖313在垂直于转轴321方向上的截面可以为圆弧形,以使折叠屏设备的侧面轮廓较为美观。
转轴组件3中,第一轴盖311和第二轴盖313之间会具有一定的间隔,从而在第一轴盖311和第二轴盖313之间形成一个容纳空间,而定位件312即可设置在该容纳空间内,并和转轴组件3的其它部件相互配合,以对电连接线4进行定位。
上述通过第一轴盖311和第二轴盖313共同形成容纳空间,并将电连接线4收容在该容纳空间内部,电连接线4得到了第一轴盖311和第二轴盖313的遮挡和保护,结构可靠性较高,且美观性较好。
图11是本申请实施例提供的折叠屏设备中连接结构的局部截面示意图。如图11所示,为了对电连接线4进行定位,转轴组件3中的定位件312固定在第一轴盖311和第二轴盖313之间,且定位件312和第一轴盖311共同将电连接线4夹设在其中,并对电连接线4起到一定的约束作用。此时,定位件312和第一轴盖311共同形成了位于电连接线4中段的一个定位点。和现有的电连接线4仅依靠两端与框体连接,而电连接线4中段处于自由弯折的悬空状态相比,本申请中的电连接线4的中段和端部位置均得到了定位,因而电连接线4的能够自由弯折的部分长度变短,相应的,弯折变形幅度也得以减小;同时,因为转轴组件3位于两个框体之间,所以转轴组件3所形成的定位点,也会将整个电连接线4在长度方向上分为长度接近的两段,这两段电连接线4的弯折变形量也较为相近,且所产生的形变和位移较为同步。这样,得到转轴组件3的辅助定位的电连接线4,其在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。
其中,第一轴盖311为和定位件312相对固定时,可以让定位件312仅和第一轴盖311 连接固定;也可以是第一轴盖311和第二轴盖313共同对定位件312进行固定。而根据不同的连接方式,定位件312可以具有不同的结构。本实施例中,以第一轴盖311和第二轴盖313共同固定定位件312为例,对定位件312在转轴组件3内的固定和连接方式进行具体说明。
图12是本申请实施例提供的折叠屏设备中连接结构的截面示意图。图13是本申请实施例提供的折叠屏设备中连接结构的结构示意图。如图12和图13所示,第一轴盖311和第二轴盖313共同围成一收容空间,而定位件312即可安装在该收容空间内。其中,定位件312的一侧结构会安装在第一轴盖311的面向第二轴盖313的面上,而定位件312的另一侧结构可以和第二轴盖313的内表面抵接。而电连接线4则被夹设在定位件312和第一轴盖311之间。其中,在图13中,为便于观察连接结构31,隐藏了第二轴盖313,而本领域技术人员可以借助其它附图而清楚的得知第二轴盖313相对于连接结构31的其它部件的位置和连接关系。
转轴组件3中的连接结构31在定位电连接线4时,连接结构31和电连接线4之间的具体位置关系可由图13至图16所示。图14是图13中的连接结构的分解示意图。图15是本申请实施例提供的折叠屏设备中连接结构在另一方向的结构示意图。图16是图15中的连接结构的分解示意图。其中,和图13类似,为便于观察连接结构31,图15中隐藏了第一轴盖311和第二轴盖313,而本领域技术人员可以借助其它附图而清楚的得知第一轴盖311和第二轴盖313相对于连接结构31的其它部件的位置和连接关系。
如图14至图16所示,柔性电路板41和线缆42等电连接线4会位于定位件312以及第一轴盖311之间,而定位件312则位于第一轴盖311和第二轴盖313之间。其中,定位件312、第一轴盖311和第二轴盖313之间的相互配合结构和具体连接方式已在前述实施方式中进行了详细介绍,此处不再赘述。
需要说明的是,定位件312和第一轴盖311共同对电连接线4进行定位时,不需要让定位件312和第一轴盖311夹紧在电连接线4的相对两侧,而仅需要定位件312和第一轴盖311共同限定出用于定位电连接线4的空间区域,并将电连接线4限制在该空间区域内即可。此时,定位件312和第一轴盖311之间实际形成了可供电连接线4穿过的通道。该通道具有由定位件312和第一轴盖311分别构成的相对两侧通道壁,而通道的两端分别和两个框体内部的空间连通,因而电连接线4可以由其中一个框体进入该通道,并通过该通道而延伸至另一个框体上。电连接线4的位于定位件312和第一轴盖311之间的部分在具有弯曲变形的趋势时,就会受到通道壁的限制,即该部分只会被限制在通道内侧的区域中,而无法大幅弯曲至通道之外。
此时,定位件312和第一轴盖311在Z轴方向上夹持电连接线4,因此,电连接线4的被夹持的部分会在Z轴方向上得到约束,无法产生大幅度的弯曲位移。受到定位件312以及电连接线4端部的约束,电连接线4的未被定位件312所夹持的部分,其弯曲形变幅度也会大幅减小,电连接线4的整体位移和形变量得以控制。
可以理解的是,因为连接结构31和转轴组件3中的铰链32等部件位于沿转轴321轴向上的不同位置,因此,连接结构31所形成的通道,也会和铰链32等用于和框体连接的部件处于转轴321轴向上的不同位置。这样在铰链32中的铰接臂322等结构带动框体绕转轴321转动时,组成通道的定位件312和第一轴盖311等部件仍然具有相对静止的位置, 通道不会因为转轴321的转动而产生形变或者其它状态改变,通道的结构较为稳定和可靠。
为了对电连接线4进行进一步辅助固定,同时降低定位件312和电连接线4之间的安装难度,可以利用磁性件或者其它可相对吸附的元件之间的吸附力,将电连接线4预先定位在转轴组件3上。
具体的,由前述内容可知,转轴组件3中的第一轴盖311和定位件312共同夹持并定位电连接线4,因而可以设置可以相互吸附的第一磁性件314以及第二磁性件315,第一磁性件314和第二磁性件315中的至少一者会和转轴组件3整体相对固定,且第一磁性件314和第二磁性件315位于电连接线4的相对两侧,以利用第一磁性件314和第二磁性件315的相互吸附力,将电连接线4预定位在转轴组件3上。
其中,第一磁性件314和第二磁性件315可以由永磁材料或者是软磁材料构成。可选的,第一磁性件314和第二磁性件315可以一者为磁铁,而另一者为软磁体。例如是第一磁性件314为磁铁,而第二磁性件315为软磁体;或者第一磁性件314为软磁体,第二磁性件315为磁铁。或者作为另一种可选的方式,第一磁性件314和第二磁性件315也可以均为磁铁,且第一磁性件314和第二磁性件315具有相反的极性。其中,软磁体可以为能够被磁化的铁质件或者钢制件等。
在利用第一磁性件314和第二磁性件315对电连接线4进行辅助定位时,第一磁性件314和第二磁性件315可以具有多种不同的安装位置。其中,在装配转轴组件3时,需要先将第一轴盖311和转轴组件3的其它主体结构装配在一起,并作为安装基准,然后再依次安装电连接线4、定位件312以及第二轴盖313等结构,所以第一磁性件314或者第二磁性件315会安装于第一轴盖311。
在其中一种可选的安装方式中,第一磁性件314可以设置在第一轴盖311上,而第二磁性件315位于定位件312上。由于定位件312和第一轴盖311处于电连接线4的不同侧,所以可以只需要让定位件312和第一轴盖311相互靠近,定位件312和第一轴盖311即可直接依靠磁力作用,将电连接线4夹持住,完成电连接线4以及定位件312等部件的预定位。电连接线4和定位件312装配完成后,第一磁性件314和第二磁性件315也可以依靠相互吸附的磁力,使定位件312和第一轴盖311之间产生相互靠近的力矩,从而对电连接线4进行辅助定位。
而由于部分电连接线4可能会以排线的形式存在,并具有较大的宽度和覆盖面积,所以在另一种可选的安装方式中,可以利用电连接线4来承载磁性件。具体的,第一磁性件314可以设置在第一轴盖311上,而第二磁性件315设置在电连接线4上。这样,第二磁性件315可以和第一磁性件314相互吸附,并和电连接线4一同定位在第一轴盖311上。该种安装方式,不需要定位件312的参与,即可实现电连接线4在第一轴盖311上的预先定位。
在该种安装方式中,第二磁性件315具体可以通过多种方式设置在电连接线4上。可选的,第二磁性件315可以通过粘接等方式设置在电连接线4的板面上,从而和电连接线4连接为一体;或者是在电连接线4上设置能够承载第二磁性件315的承载结构,并将第二磁性件315安装于该承载结构中,以实现电连接线4和第二磁性件315的相对定位。
需要说明的是,上述各安装方式中,由于第一磁性件314和第二磁性件315不需要相互接触即可实现相互吸附,所以第一磁性件314和第二磁性件315可以设置在第一轴盖311、 定位件312以及电连接线4上的不同位置,只要第一磁性件314和第二磁性件315具有相对的位置,能够通过两者之间的磁力作用而让定位件312和第一轴盖311相互靠近即可。此外,为便于安装,第一磁性件314和第二磁性件315可以具有较为规则的外形,示例性的,第一磁性件314和第二磁性件315均可以为长方体。
此外,也可以令第一磁性件314与第一轴盖311,或者第二磁性件315与定位件312形成一体式结构。此时,连接结构31中实际上仅包括第一磁性件314或者仅包括第二磁性件315,而相应的,定位件312或者是第一轴盖311则整个由软磁体构成。示例性的,第一轴盖311上设置有第一磁性件314,且第一磁性件314为磁铁,而定位件312整个为能够被磁铁所吸附的软磁体;或者是在定位件312上设置有第二磁性件315,第二磁性件315为磁铁,而第一轴盖311由软磁体构成。这样可以简化第一轴盖311或者是定位件312的结构,降低制造难度。
这样通过磁性件的磁力作用,可以在转轴组件3的装配过程中,预先将电连接线4设置在装配组件上,避免电连接线4因外界拉扯或者是其它作用力而脱离装配位置,有效减小了装配难度;同时,磁性件的吸附作用,也能够让第一轴盖311和定位件312之间压紧,或者使电连接线4贴合在第一轴盖311上,从而对电连接线4进行辅助定位。
为了完成连接结构内部各部件之间的连接,除了磁性件之外,各部件之间也会具有可相对配合的结构。图17是本申请实施例提供的折叠屏设备中第一轴盖的结构示意图。如图17所示,第一轴盖311可以占据转轴组件3的整个长度方向,以作为连接结构31和铰链32之间的连接基础。而定位件312以及第二轴盖313,即可利用第一轴盖311作为定位和装配基准而进行组装。具体的,第一轴盖311包括有位于第一轴盖311的中部区域的第一固定面3111,以及位于端部区域的连接柱3112。其中,连接柱3112可以用于和铰链32或者是其它结构连接;而第一固定面3111则可以用于安置定位件312。为了使转轴组件3均衡受力,连接柱3112在第一轴盖311的长度方向上对称分布。
此外,为了将第一磁性件314安装于第一轴盖311上,第一轴盖311的第一固定面3111上可以开设有第一安装槽3113。第一安装槽3113的形状和大小均与第一磁性件314相匹配,从而可以让第一磁性件314收容于第一安装槽3113之内。其中,可选的,第一安装槽3113可以通过粘接剂或者是过盈配合等方式与第一磁性件314连接。
图18是本申请实施例提供的折叠屏设备中第二轴盖的结构示意图。如图18所示,第二轴盖313会一直延伸至转轴组件3的整个长度方向,与第一轴盖311类似。而第二轴盖313的内表面呈圆弧形。
为了连接至第一轴盖311及第二轴盖313,定位件312上具有相应匹配连接的结构。图19是本申请实施例提供的折叠屏设备中定位件的正面结构示意图。图20是本申请实施例提供的终端设备中定位件312的背面结构示意图。如图12至图20所示,在一种可选的实施方式中,定位件312的靠近第一轴盖311的一侧具有第一定位部3122,第一定位部3122可以和第一轴盖311连接,从而让定位件312和第一轴盖311具有固定的相对位置。定位件312的靠近第二轴盖313的一侧具有第二定位部3121,第二定位部3121可以和第二轴盖313连接,以使定位件312和第二轴盖313之间具有固定的相对位置。
因为定位件312位于第一轴盖311和第二轴盖313之间,所以第一轴盖311和第二轴盖313可以共同将定位件312夹设在其中。此时,第一定位部3122和第二定位部3121均 可以为定位柱或者定位凸起等结构,且第一定位部3122和第二定位部3121分别抵接于第一轴盖311或者是第二轴盖313的相对的表面,使定位件312稳固的被夹持在第一轴盖311和第二轴盖313之间。
具体如图19和图20所示,定位件312的第一定位部3122会由定位件312的主体向外凸出,且第一定位部3122的顶端高度会高于定位件312该侧表面其它部分的高度,因而第一定位部3122和第一轴盖311连接时,就会使定位件312的主体和第一轴盖311之间形成一定的间隙,该间隙可以用于穿设电连接线4。
上述定位件结构中,为了让定位件312和第一轴盖311共同夹持并定位电连接线4,作为一种可选的方式,定位件312的主体的面向第一轴盖311的一侧还具有第二固定面3125,第二固定面3125和第一轴盖311之间形成上述用于穿设电连接线4的间隙,能够将电连接线4夹设在第一轴盖311和第二固定面3125之间的区域内,而电连接线4的被定位件312与第一轴盖311所夹持的部位,其位置被限制,无法随框体的转动而产生大幅的弯曲和变形。
此时,由于定位件312会通过第一定位部和第一轴盖311连接,所以第一定位部会朝第二固定面3125的外侧凸出,直至和第一轴盖311的相应部位抵接。为了让第二固定面3125的各个部位均与第一轴盖311之间保持间距,第一定位部3122可以为多个,且分布在定位件312的主体的不同位置。本实施例中,第一定位部3122为两个,且设置在定位件312的主体的相对两侧。其中,为了在保持第二固定面3125和第一轴盖311之间间距的同时,减少第一定位部对第二固定面3125的影响,多个第一定位部3122之间会具有较大的间隔,且第一定位部3122可以具有较小的横截面积。这样第二固定面3125能够具有较大的区域面积。其中,第一定位部3122可以为凸柱形式。
而为了和第二轴盖313相对固定,定位件312上还包括第二定位部3121。第二定位部3121可以为凸起等结构,并可以和第二轴盖313的内表面抵接。此时,凸起的顶端可以为和第二轴盖313内表面形状相匹配的圆弧状,这样第二定位部3121的顶端会和第二轴盖313内表面牢固抵接并得到定位。
和第一定位部3122类似,第二定位部3121也可以为多个,且分布在定位件312的不同位置。本实施例中,第二定位部3121同样可以为两个,并分别设置在定位件312的长度方向的两个端部位置。这样通过不同位置的第二定位部3121的连接,定位件312和第二轴盖313之间可以进行可靠的定位。
为避免电连接线4从定位件312和第一轴盖311之间的区域中脱离,定位件312上可以设置有限制电连接线4产生横向(即图中Y轴方向)移动的结构。示例性的,定位件312可以利用定位凸起等结构来限定电连接线4的横向位置。如图20所示,作为其中一种可选的结构,在定位件312的主体上可以设置有第三定位部3127,在定位件312和第一轴盖311之间设置电连接线4时,第三定位部3127会位于电连接线4的侧方,从而阻止电连接线4向侧方的第三定位部3127移动的趋势。
其中,第三定位部3127可以为凸出于第二固定面3125的凸起等结构,这样电连接线4会受到第三定位部3127的侧壁的约束,因而在平行于第二固定面3125的方向(图中的Y轴方向)的移动受到阻碍。第三定位部3127可以为一个,也可以具有多个。例如第三定位部3127可以为两个,且设置在电连接线4的不同侧,以分别约束电连接线4向两个第 三定位部3127所在方向的移动趋势;此外,由于定位件312的主体需要通过第一定位部3122和第一轴盖311连接,所以第三定位部3127可以和第一定位部3122相互配合对电连接线4进行横向定位。此时,只需要第三定位部3127位于电连接线4的一侧,而电连接线4的另一侧为第一定位部3122,第一定位部3122和第三定位部3127即可共同约束电连接线4的横向位置。
其中,为了提高第三定位部3127的限位效果,第三定位部3127可以沿着电连接线4的长度方向延伸,以对电连接线4在长度方向上的不同部位进行定位。
此外,可以理解的是,为了将磁性件固定在定位件312上,定位件312上开设有第二安装槽3129。第二安装槽3129的大小和形状均与第二磁性件315相匹配,从而让第二磁性件315固定在定位件312中。具体的,第二安装槽3129可以位于定位件312的面向第一轴盖311的一面,也就是第二固定面3125上。此外,第二磁性件315可以通过粘接或者过盈配合等方式与第二安装槽3129连接。
同时,第一轴盖311或者是第二轴盖313上可以与定位件312具有相互匹配的结构。示例性的,在第一轴盖311以及第二轴盖313的至少一者上,可以设置形状与第一定位部3122或者是第二定位部3121相匹配的结构,例如是凹槽或者定位孔等(图中未示出)。这样第一定位部或者第二定位部可以插入凹槽或定位孔之中,从而完成定位件312相对于第一轴盖311以及第二轴盖313的固定。
此外,可以理解的是,在其它可选择的方式中,定位件312还可以仅和第一轴盖311连接固定。此时,定位件312可以通过卡接等方式与第一轴盖311连接在一起。
本领域技术人员容易理解的是,除了卡接和抵接等方式之外,定位件312还可以通过螺纹紧固件或者是粘接等方式,与第一轴盖311、第二轴盖313或者是转轴组件3的其它结构连接并固定,此处对定位件312在连接结构31中的其它连接方式不再赘述。
在折叠屏设备进行折叠时,随着两个框体的相对转动,电连接线4在沿自身长度所在的方向上也可能会发生移动,即电连接线4沿X轴方向和定位件312产生相对滑移。这样电连接线4在定位件312两侧的长度有可能存在较大的长度差,而较长的一部分仍有可能产生较大幅度的弯折变形。为了减少或避免电连接线4在沿长度方向上相对于定位件312的滑移,定位件312上可以设置有相应的限位结构。
定位件312的限位结构在限制电连接线4的滑移时,具体可以利用电连接线4自身可以弯曲形变的特性,通过限位结构的限制和引导,使电连接线4的不同部分或者不同段具有不同的延伸方向。当电连接线4受到外力影响,而产生沿自身长度方向的移动趋势时,电连接线4的向不同方向延伸的各部分,其长度方向和受到的外力方向不一致,这样电连接线4与侧方的其它结构之间会随外力而相应产生一定的摩擦力和阻力,增大使电连接线4移动所需的外力大小,减缓甚至消除电连接线4沿自身长度方向的移动趋势。
因为电连接线4中可以包括柔性电路板41以及单根的线缆42等多种不同类型,而对于不同类型的电连接线4,定位件312上可以用不同的限位结构来完成对电连接线4的定位。以下分别以对柔性电路板41以及单根线缆42进行定位为例,对定位件312的限位结构进行详细说明。
对于柔性电路板41而言,由于柔性电路板41的整体为一可弯曲的薄板状结构,其具有较长的宽度和长度,而柔性电路板41的厚度方向,也就是与柔性电路板41板面方向所 垂直的方向上的尺寸较小。因而为了减小限位结构的尺寸,定位件312的限位结构对柔性电路板41进行进一步限位时,可以在与柔性电路板41板面方向垂直的方向上对柔性电路板41进行限位固定。
具体的,定位件312的限位结构可以位于柔性电路板41的板面的一侧,并让柔性电路板41产生一定弯曲,而弯曲方向与柔性电路板41的板面方向垂直。柔性电路板41具有和板面方向相垂直的弯折部位时,柔性电路板41的弯折部位的延伸方向和柔性电路板41的整体长度方向不同,因而位于柔性电路板41外侧的限位结构会阻碍柔性电路板41沿柔性电路板41整体长度方向的移动,使电连接线4被限制在原先的位置。
其中,图21是本申请实施例提供的折叠屏设备中连接结构和柔性电路板的连接示意图。如图21所示,作为一种可选的实施方式,第一轴盖311上的第一固定面3111和定位件312的第二固定面3125都可以为凹凸表面,且凹凸表面的凹凸方向朝向柔性电路板41的厚度方向。由于定位件312会和第一轴盖311共同将柔性电路板41夹设在其中,所以柔性电路板41的板面会呈现出和第一固定面3111以及第二固定面3125相匹配的形状,即同样会朝向自身的厚度方向弯折并形成凸起或凹陷。这样定位件312即可通过具有凹凸形状的第二固定面3125,完成对柔性电路板41在自身长度方向上的固定。
此时,定位件312和第一轴盖311之间会形成一具有凹凸形状的通道,而穿过该通道的柔性电路板41也会形成相应的凹凸形状,这样柔性电路板41会和凹凸起伏的通道壁接触,并被通道壁所阻碍,避免柔性电路板41在自身长度方向上出现前后移动。
具体的,第一轴盖311的第一固定面3111和定位件312的第二固定面3125所形成的凹凸形状可以为一个,也可以为多个。而当第一固定面3111和第二固定面3125的凹凸形状具有多个时,多个凹凸形状可以沿柔性电路板41的长度方向依次排列。这样柔性电路板41可以同时受到多个凹凸形状的限制,并相应具有多个弯曲段或者弯折段。而多个弯曲段或弯折段可以共同作用并产生阻力,对于柔性电路板41在长度方向上的定位效果较好。
第一固定面3111和第二固定面3125的凹凸形状具有多个时,凹凸形状的形状以及单个凹凸形状的大小会受到柔性电路板41本身弯折性能的限制。示例性的,单个凹凸形状的凸起或凹陷高度会大于柔性电路板41自身的最小可弯折半径,以避免柔性电路板41过度弯曲而产生破损甚至断裂现象。
而为了简化定位件312的结构,减低制造成本,第一轴盖311的第一固定面3111和定位件312的第二固定面3125可以具有较为简单的形状。此时,第一固定面3111和第二固定面3125均可以具有一个凸起或者凹陷形状。该凸起或者凹陷形状会和第一轴盖311上的相应部位的形状相匹配,从而让柔性电路板41在第二固定面3125与第一轴盖311之间所形成的空间内整体具有一个弯曲部分或者弯折部分,且弯曲部分会与第二固定面3125的凸起或者凹陷部位抵接,从而在柔性电路板41长度方向上实现定位。本实施例中,以第二固定面3125上具有凹陷形状,而第一固定面3111上具有相应的凸起形状为例进行说明。
当第一固定面3111和第二固定面3125为凹凸表面时,可选的,第一固定面3111和第二固定面3125可以由直线弯折的方式产生凸起或凹陷形状。示例性的,如图21所示,第一固定面3111上具有多个直线弯折段3111a,而第二固定面3125上也相应具有多个直线弯折段3125a;第一固定面3111上的各直线弯折段3111a会形成凸起形状;而相应的,第 二固定面3125上的各直线弯折段3125a会形成凹陷形状,这样第一固定面3111和第二固定面3125的形状相互匹配,形成了呈弯折状的通道,且通道会凸向定位件312一侧。这样利用直线弯折形成的凸起和凹陷可以具有较大的弯折角度,对柔性电路板41具有较好的固定效果。
而在另一种可选的结构中,第二固定面3125可以为弧形面,且第一轴盖311的面向第二固定面3125的第一固定面3111也呈弧形面。此时,第一固定面3111和第二固定面3125上不存在锐棱或者是尖角等折角结构,柔性电路板41与定位件312接触的部位,以及柔性电路板41和第一轴盖311接触的部位均为平滑过渡的弧形表面,柔性电路板41表面不会因锐棱的压迫而产生折痕或者是表面划伤。
此外,定位件312还可以具有其它用于对柔性电路板41在长度方向上进行定位的结构或形状,此处不再赘述。
需要说明的是,电连接线4中,可能包括一个或一个以上柔性电路板41。在柔性电路板41的数量为一个以上时,可以让多个柔性电路板41上下相叠设置,并共同被转轴组件3中的第一轴盖311和定位件312所固定。
而电连接线4中,除了柔性电路板41之外,还可能具有零散排布的线缆42。和柔性电路板41不同,线缆42一般呈单根设置,这样线缆42的径向尺寸会远小于线缆42在长度方向上的尺寸。因此,定位件312在定位线缆42时,相较柔性电路板41而言,所需要的限位结构可以具有更为紧凑的尺寸。
具体的,在一种可选的实施方式中,在定位件312的第二固定面3125上开设有导向槽3123,线缆42的处于定位件312与第一轴盖311之间的线缆段,可以部分处于或者全部埋设于导向槽3123内部。
而为了在线缆42长度方向上对线缆42进行定位,减少或避免线缆42在沿长度方向上相对于定位件312的滑移,导向槽3123可以相应具有多种不同的导向槽形状和结构,并和线缆42之间进行配合定位。以下对导向槽3123的各种可能的形式以及相应的线缆42限位方式进行具体说明:
图22是本申请实施例提供的一种线缆的结构示意图。如图22所示,作为一种可选的实施方式,线缆42的外表面可以设置有定位结构,定位结构可以和导向槽3123的相应结构相配合,以实现定位件312对线缆42在沿线缆42长度方向上的定位。
可以理解的是,由于线缆42被固定在定位件312的导向槽3123中,所以导向槽3123中可以设置与线缆42的定位结构相匹配的结构。具体的,线缆42外表面的定位结构可以为轴向定位凸起421,轴向定位凸起421的凸出方向沿线缆42的径向。
图23是本申请实施例提供的一种定位件在和线缆连接时的第一方向上的连接结构示意图。图24是本申请实施例提供的一种定位件在和线缆连接时的第二方向上的连接结构示意图。如图23至图24所示,具体的,导向槽3123可以沿线缆42的长度延伸方向贯穿定位件312,导向槽3123的槽口面向第一轴盖311,且导向槽3123在定位件312的相对两侧端面上形成开口,而线缆42即可通过相对设置的两个开口穿入导向槽3123内部,导向槽3123的两侧槽壁可以限制线缆42在径向上的位置,从而将线缆42约束于导向槽3123内。
而和线缆42上的轴向定位凸起421相对应,导向槽3123中可以设置有与轴向定位凸 起421相对应的凹陷部3124,凹陷部3124的形状和位置均和轴向定位凸起421的形状及位置相对应,线缆42设置在导向槽3123中时,线缆42的轴向定位凸起421会位于凹陷部3124之内,凹陷部3124的侧壁即可限制线缆42沿长度方向的位移。
其中,线缆42的定位结构可以具有多种不同形式。可选的,可以利用注塑件形成线缆42的定位结构,注塑件可以通过注塑成型的方式形成于线缆42的外表面,且注塑件和线缆42的本体之间具有较高的连接强度,结构较为可靠。此外,也可以利用其它材料或部件在线缆42的外表面形成定位结构,此处不加以限制。
本领域技术人员容易理解的是,由于轴向定位凸起421突出于线缆42的外表面,为了将具有轴向定位凸起421的线缆42容置于导向槽3123之中,导向槽3123应具有便于线缆42放入的避让缺口3126。
避让缺口3126的大小和形状会适应于具有轴向定位凸起421的线缆42。具体的,避让缺口3126在线缆42径向的尺寸大小,会大于具有轴向定位凸起421的线缆42的最大径向尺寸,从而可以让线缆42通过避让缺口3126放入导向槽3123内。避让缺口3126的位置和凹陷部3124可以相对或者错开,线缆42进入导向槽3123后,即可移动至轴向定位凸起421与凹陷部3124匹配卡合的位置,以使线缆42得到定位,具体如图22所示。
此外,开设有避让缺口3126和导向槽3123的定位件312,其主体具有较为复杂的形状轮廓,而定位件312可以采用注塑等方式实现一体成型。相应的,在一种可选的方式中,在定位件312上可以开设有工艺孔3128,避让缺口3126和凹陷部3124均与工艺孔3128连通,从而让模具可以通过工艺孔3128而伸入避让缺口3126和凹陷部3124内部,便于定位件312的注塑成型。其中,工艺孔3128等结构的具体形状和位置可以参照前述关于定位件312的图示。
可选的,导向槽3123可以朝向柔性电路板41的厚度方向弯曲,例如是导向槽3123可以形成与第二固定面3125相似的凹凸形状,从而完成对线缆42在线缆42长度方向上的限位。具体的,如图22所示,导向槽3123的边缘高度会高于导向槽3123中部的高度,从而在导向槽3123的边缘形成台阶3123a,台阶3123a的具体形状及结构可参照前述关于定位件312的图示。导向槽3123在朝向柔性电路板41厚度方向弯曲时,导向槽3123所形成的的凹凸形状的具体结构和前述第二固定面3125的凹凸结构较为相似,具体可以参照前述关于第二固定面3125的凹凸结构的叙述,此处不再赘述。
作为另一种可选的方式,导向槽3123还可以单独利用弯折形状实现对线缆42在长度方向上的限位。图25是本申请实施例提供的另一种定位件在连接线缆时的连接结构示意图。如图25所示,定位件312的导向槽3123会具有至少一个弯折段。弯折段的弯折方向会朝向线缆42的径向,设置在导向槽3123内的线缆42,在导向槽3123的槽壁迫使下形成弯折形状。当线缆42具有沿自身长度方向移动的趋势时,导向槽3123的弯折的槽壁即可阻碍线缆42的移动,使线缆42维持在原来的位置。此外,可选的,导向槽3123的弯折方向可以凸向柔性电路板41一侧,这样在导向槽3123的导向作用下,线缆42的端部会向远离柔性电路板的一侧延伸,可以防止线缆42和柔性电路板41产生干涉。
和柔性电路板41具有较宽的宽度不同,线缆42在各方向上的径向尺寸均较小,因此导向槽3123可以直接将线缆42夹设在其中,而不再需要通过第二固定面3125和第一轴盖311的配合完成对柔性电路板41在X轴方向上的限位。这样,导向槽3123可以具有均 匀一致的槽深,而导向槽3123的两侧槽壁之间的槽宽可以与线缆42的外径相匹配,以完成对线缆42的限位和固定。
具体请参照图25,导向槽3123整体沿着定位件312的宽度方向(Y轴方向)延伸,且导向槽3123具有弯折段,弯折段的弯折方向朝向定位件312的长度方向(图中X轴方向)。为了对线缆42形成较好的定位效果,图25中的导向槽3123具有多个依次连接的弯折段,这些弯折段会将线缆42的多个不同的线缆42段分别导向不同的方向,导向槽3123对线缆42会产生较大的阻力,阻止线缆42沿长度方向相对于线槽滑动。
如图25所示,作为导向槽3123的一种可选的结构,导向槽3123中的各弯折段可以相对于定位件312的中轴线对称设置。此时,以定位件312的中轴线为界,将线缆42分为连接至不同框体的两段,而位于中轴线不同侧的各弯折段,其对线缆42所施加的阻力也是接近甚至一致的,线缆42在弯曲变形时,位于定位件312两侧的线缆段的受力和变形会较为一致,而不会出现定位件312一侧线缆42变形较大,而定位件312另一侧线缆42变形较小的情况。
其中,导向槽3123具有多个弯折段时,各弯折段之间可以通过曲面平滑过渡,以避免导向槽3123出现尖角或锐棱而划伤线缆42。
和对柔性电路板41的固定类似,在导向槽3123对线缆42进行限位时,弯折段所形成的弯折角度以及弯折半径会大于线缆42的最小可弯折半径,以避免导向槽3123的弯曲程度过大,而使位于导向槽3123内的线缆42产生损坏或折断。
在定位件312和第一轴盖311对电连接线4进行定位时,可以利用粘接剂对柔性电路板41和线缆42等进行辅助定位。此时,可以在柔性电路板41或者是线缆42的与转轴组件3接触的部位进行点胶操作,并利用粘接剂的粘接力使柔性电路板41或者线缆42与定位件312固定在一起。
在电连接线4中,可能会同时具有柔性电路板41以及呈单根排布的线缆42。为了让定位件312同时对柔性电路板41和单根线缆42实现定位,定位件312的导向槽3123会位于第二固定面3125的与柔性电路板41贴合的区域之外,也就是说,导向槽3123和第二固定面3125的用于定位柔性电路板41的区域并列设置。相应的,柔性电路板41和呈单根分布的线缆42也会并列排布。
为了让电连接线4的端部连接至相应的框体,在框体上也具有用于固定电连接线4的固定结构。这样电连接线4的端部和框体之间具有确定的相对位置,无论框体旋转至任意位置,电连接线4的端部均会可靠连接至框体上,并和框体中的主板、天线或者柔性屏体等相应部件保持电性连接。
其中,由于电连接线4中可以包括柔性电路板41以及独立线缆42等不同组成部分,且柔性电路板41和独立的线缆42具有不同的结构和形状,所以对于柔性电路板41和线缆42,框体可以分别通过不同的固定结构对其端部进行固定。
图26是本申请实施例提供的折叠屏设备中电连接线和框体之间的连接结构示意图。图27是图26中电连接线和框体之间连接结构的分解示意图。如图26和图27所示,作为一种可选的实施方式,在柔性电路板41的端部设置有补强钢片411,补强钢片411可以通过粘接或压合方式与柔性电路板41的端部连接在一起,且补强钢片411具有较强的机械性能,可以设置固定结构,并承担在柔性电路板41固定时的拉扯作用力。具体的,以电连 接线4和第一框体连接为例,柔性电路板41端部的补强钢片411上设置有第一连接孔4111,第一连接孔4111的朝向与柔性电路板41的板面方向垂直;而第一框体1上设置有与第一连接孔4111相对应的第二连接孔11。当补强钢片411的第一连接孔4111与第一框体1上的第二连接孔11匹配对应时,即可让固定件依次穿过第一连接孔4111和第二连接孔11,从而将柔性电路板41的端部固定于第一框体1上。
具体的,由于柔性电路板41的主体由聚酯薄膜等材料构成,结构强度较差,不易设置开孔等结构,所以柔性电路板41的端部设置有补强钢片411,在补强钢片411上设置有第一连接孔4111。第一连接孔4111和第二连接孔11匹配对应时,第一连接孔4111和第二连接孔11相对且同心设置,从而可以依靠同一固定件进行固定。其中,固定件可以为常用的紧固件,例如螺钉等螺纹紧固件,或者是螺柱、铆钉等其它本领域技术人员常用的紧固件等,此处不加以限制。
其中,补强钢片411在自身维持较小的厚度的同时,具有较强的机械强度,所以可以对柔性电路板41的端部实现可靠固定。补强钢片411的长度方向可以和柔性电路板41的宽度方向保持一致,这样在柔性电路板41的整个宽度方向上,柔性电路板41都会被补强钢片411所压紧固定,对柔性电路板41的端部可以实现较好的定位效果。
将柔性电路板41的端部固定在框体上时,作为一种可选的方式,在框体上可以设置弹性缓冲垫412,弹性缓冲垫412位于框体和补强钢片411之间。此时,由于弹性缓冲垫412自身具有一定的可变形能力,所以补强钢片411和对应的框体之间会形成一定的间隙,而补强钢片411相对于框体的轴向位置即可在该间隙的范围内变化,从而可以对柔性电路板41的端部和框体之间的连接点位置进行小幅度调整。此时,即使柔性电路板41的端部与框体之间连接点位置存在小幅的位置误差,例如是柔性电路板41的长度不足以抵达与框体的连接点时,也能通过弹性缓冲垫412的弹性变形,而对该误差进行补偿,避免柔性电路板41因长度不足而出现绷紧甚至是断裂的风险。
此外,弹性缓冲垫412可以由泡棉等具有一定柔韧性的材料制成,因而也能够保护在柔性电路板41的端部表面,避免柔性电路板41的外表面在外力作用下受到损伤。可选的,缓冲垫412可以覆盖在柔性电路板41的端部与连接件之间对应连接的区域。而为了提高柔性电路板41和其它部件之间的绝缘性能,弹性缓冲垫412可以由绝缘泡棉构成。
此外,为了对补强钢片411进行辅助固定,可选的,在框体上还可以设置有定位钢片,且定位钢片上开设有第三连接孔。定位钢片可以设置于压在补强钢片411上,且定位钢片位于补强钢片411的背离框体的一侧。此时,固定件可以依次穿过第三连接孔、第一连接孔以及第二连接孔,从而将定位钢片、弹性缓冲垫412、补强钢片411以及框体在固定件的轴向上固定在一起。
此时,弹性缓冲垫412可以具有多种不同位置,除了将弹性缓冲垫412设置在补强钢片411和框体之间外,还可以让弹性缓冲垫412位于定位钢片和补强钢片411之间;或者,在补强钢片411与框体之间,以及定位钢片和补强钢片411之间均可以设置有弹性缓冲垫412。
而将线缆42固定在框体上时,作为可选的实施方式,在框体上可以开设有线槽12,而线缆42埋设在线槽12之中。通过线槽12,可以对线缆42的位置和走向进行约束。
为了避免线缆42从线槽12内部脱离,框体可以利用其它定位结构或者是定位方式对 线缆42进行辅助定位。在一种可选的方式中,线缆42和线槽12之间可以通过粘接剂进行粘接。具体的,可以在将线缆42安装于线槽12内部后,通过点胶的方式,使线缆42和线槽12粘接在一起。
而在另一种可选的方式中,补强钢片411也可以用于辅助定位线缆42。具体的,补强钢片411可以覆盖线槽12所在的区域,并压设在线缆42的外侧。此时,线缆42在周向上的各方向位移均会受到补强钢片411或者是线槽的约束,因而线缆42的位置得以限定。此时,用于定位柔性电路板41以及线缆42的为同一块补强钢片411。这样可以有效利用折叠屏设备内部的有限空间,使设备更为紧凑。
此外,也可以采用其它具有较好机械性能的材料来代替补强钢片411。示例性的,可以采用高强度塑胶材料来实现对柔性电路板41端部的补强和定位。
可选的,在线缆42表面还可以包裹醋酸布,从而对线缆42进行保护。醋酸布可以位于线缆42外表面与其它结构的接触面之间,并具有一定的缓冲和绝缘效果。此外,线缆42表面还可以利用注塑结构或者是本领域技术人员熟知的其它方式对线缆42表面进行保护,此处不加以限制。
此外,为了固定柔性电路板41或者是线缆42的端部,框体上还可以具有其它形式和结构的定位结构及定位部件,此处不加以限制。
对电连接线4进行定位和固定后,电连接线4仍具有一定的自由形变能力,因而折叠屏设备在开合时,电连接线4可能和电连接线4外侧的其它部件或结构发生剐蹭现象。为了避免电连接线4和其它结构产生剐蹭,作为一种可选的实施方式,在两个框体的结合部位还设置有柔性防护罩。图28是本申请实施例提供的折叠屏设备中柔性防护罩的内侧连接示意图。图29是本申请实施例提供的折叠屏设备中柔性防护罩的外侧连接示意图。如图28和图29所示,柔性防护罩5的相对两侧边缘分别用于和两个框体连接,而柔性防护罩5的主体会覆盖电连接线4的侧方,在折叠屏设备开合时,柔性防护罩会5阻挡在电连接线4和外侧的结构之间,避免外侧其它结构接触到电连接线4。
折叠屏设备在开合时,电连接线4中的柔性电路板41和线缆42大多会朝向折叠屏设备的内侧,也就是折叠屏设备的开合端发生弯折现象,因而相应的,柔性防护罩5设置在电连接线4的靠近折叠屏设备的开合端的一侧。其中,为了让柔性防护罩5对电连接线4起到较为全面的防护效果,柔性防护罩5在沿转轴321长度方向上的尺寸可以大于或等于电连接线4在该方向上所占的区域大小,此时电连接线4的位于两个框体之间的部分会全部被柔性防护罩5所覆盖和保护。
柔性防护罩5自身由材质较软的柔性材料构成,所以即使电连接线4和柔性防护罩5发生触碰,柔性防护罩5也不会对电连接线4的表面造成损伤。
其中,作为一种可选的方式,柔性防护罩5可以为波纹防护罩。此时,柔性防护罩5整体具有凹凸起伏的波纹形面,波纹形面可以在折叠屏设备开合时,相应进行展开或折叠,从而形成不同大小的防护区域,以适应于折叠屏设备的不同开合角度。
在折叠屏设备的不同框体中可以设置不同部件,而这些部件具有不同的功率和发热量。随着热量的聚积,不同框体可能会具有较大的温度差,从而影响到柔性屏体的和这些不同框体对应部位的显示效果,造成屏幕局部区域显示偏色等显示均匀性问题。为此,连接于不同框体之间的柔性防护罩5可以具有一定的传热能力,以在不同框体之间传递热量,减 少不同框体之间的温度差异,改善柔性屏体的显示均匀性。
具体的,柔性防护罩5可以由导热薄膜制成。导热薄膜可以由石墨或者是碳纤维等材料制成,自身具有较好的导热能力,这样连接在不同框体之间的柔性防护罩5,可以将框体上的热量传递至另一框体,使两个框体的温度较为均匀。而柔性屏体的对应设置在不同框体上的各个部位也会具有较好的显示均匀性。
此时,作为一种可选的方式,柔性防护罩5可以具有和框体(图中未示出)贴合的散热面51。散热面51具有较大的散热面积,因而柔性防护罩5可以利用散热面51和框体实现较快的热传导速度,从而令第一框体1和第二框体2之间具有较好的温度均匀性。
本实施例中,折叠屏设备包括第一框体、第二框体和连接在第一框体和第二框体之间的转轴组件,转轴组件中的连接结构形成能够穿设及固定电连接线的通道;同时在连接结构中,设置有磁性件来对连接结构和电连接线进行辅助定位。这样电连接线得到了转轴组件的定位,在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。
场景二
折叠屏设备中,在利用转轴组件3中的连接结构31对电连接线4进行定位时,也可以不采用磁性件对电连接线4进行辅助固定,而是仅利用连接结构31中定位件312和第一轴盖311之间的配合,实现对电连接线4的限位。图30是本申请实施例提供的另一种折叠屏设备中连接结构的截面示意图。图31是本申请实施例提供的另一种折叠屏设备中连接结构在第一方向的结构示意图。图32是本申请实施例提供的另一种折叠屏设备中连接结构在第二方向的结构示意图。如图30至图32所示,本实施例的折叠屏设备,其主要结构、功能和工作原理均和前述场景一中的折叠屏设备类似,此处不再赘述。本场景和前述场景一的不同之处在于,本场景的折叠屏设备,在其转轴组件3所包含的连接结构31中,并不包括磁性件。此时,连接结构31主要包括第一轴盖311、第二轴盖313和定位件312,定位件312位于第二轴盖313和第一轴盖311之间,且电连接线4会位于定位件312以及第一轴盖311之间。
具体的,本场景中,连接结构31中的第一轴盖311、第二轴盖313和定位件312具有和前述场景类似的结构,且定位件312可以通过前述场景中的具体结构而被安装于第一轴盖311和第二轴盖313之间。其中,第一轴盖311、第二轴盖313和定位件312的整体结构和相对位置可以参照前述场景一中的描述。此时,由于连接结构31中并不包含磁性件,所以定位件312的第二固定面3125,以及第一轴盖311的第一固定面3111均可以为平整表面,而不需要开设安装槽。
本实施例中,折叠屏设备包括第一框体、第二框体和连接在第一框体和第二框体之间的转轴组件,转轴组件中的连接结构形成能够穿设及固定电连接线的通道。这样电连接线得到了转轴组件的定位,在折叠屏设备折叠时所产生的弯折变形较小,且弯折量容易控制,因而具有较高的连接可靠性。
