下面结合图1至图15描述根据本发明实施例的铰链组件100。
根据本申请实施例的铰链组件100包括基座10、第一同步轴20、第二同步轴30、第一活动件41和第二活动件42。
具体而言,基座10设有第一配合部11和第二配合部12。第一同步轴20的第一端可活动地与第一配合部11连接。第二同步轴30的第一端可活动地与第二配合部12连接。第一活动件41的第一端设有第一齿轮轴套,第一齿轮轴套的外表面设有第一齿轮端411。第一齿轮端411与第一同步轴20连接且与其同步活动。
第二活动件42的第一端设有第二齿轮轴套,第二齿轮轴套的外表面设有第二齿轮端421,第二齿轮轴套与第二同步轴30连接且与其同步活动。第二齿轮端421与第一齿轮端411啮合。
换言之,根据本申请实施例的铰链组件100主要由基座10、第一同步轴20、第二同步轴30、第一活动件41、第二活动件42组成。本申请实施例的铰链组件100可以用于电子设备200。电子设备200包括第一部分201和第二部分202。
如图2和图11所示,在将电子设备200分为左机身和右机身时,第一部分201可为左机身的至少一部分,第二部分202可为右机身的 至少一部分。
在左机身和右机身之间可设有中框支架203。在左机身和右机身的同一侧可设有可折叠的柔性屏幕。基座10可设置在中框支架203上。通过本申请的铰链组件100,能够带动左机身、右机身运动,并实现柔性屏的展开和闭合。
如图3、图9和图14所示,第一活动件41可作为左同步摆臂,第二活动件42可作为右同步摆臂。第一活动件41的第一端设有第一齿轮轴套。在第一齿轮轴套的外表面设有第一齿轮端411。
第一活动件41与第一齿轮轴套一体式设计,具有结构紧凑,空间利用率高等优点。同样的,第二活动件42的第一端设有第二齿轮轴套,第二活动件42与第二齿轮轴套一体式设计,在此不作赘述。
在第一齿轮轴套的外表面设有第一齿轮端411。第一齿轮端411与第一同步轴20连接且两者同步活动。即在第一同步轴20转动时,第一齿轮端411也转动。在第二齿轮轴套的外表面设有第二齿轮端421,第二齿轮端421与第二同步轴30连接,且两者同步活动。即在第二同步轴30转动时,第二齿轮端421也转动。
也就是说,第一齿轮端411和第二齿轮端421可以配合形成同步机构的至少一部分。通过采用同步机构,能够实现左机身和右机身的同步转动。第二齿轮端421与第一齿轮端411之间啮合,可以包括直接啮合或者间接啮合两种情况。通过使第二齿轮端421与第一齿轮端411之间啮合,能够保证左、右机身转动同步,避免出现歪斜。
由于第一活动件41与第一同步轴20同步活动,因此在第一活动件41转动时,能够同时带动第一同步轴20转动,并同时带动第一活动件41上的第一齿轮轴套转动,从而带动第一齿轮端411转动。通过使第一活动件41与第一同步轴20同步活动,能够使第一同步轴20相对于基座10可活动,第一同步轴20和基座10之间的摩擦力减小。
同样的,第二活动件42与第二同步轴30同步活动,在第二活动件42转动时,能够同时带动第二同步轴30转动,并同时带动第二活动件42上的第二齿轮轴套转动,进而带动第二齿轮端421转动,在此不作赘述。
在铰链组件100折叠时,第一齿轮端411和第二齿轮端421相向旋转,在铰链组件100展开时,第一齿轮端411和第二齿轮端421相 背旋转。
在第一齿轮端411和第二齿轮端421直接啮合时,本实施例的同步链可大致为第一部分201-第一活动件41-第一齿轮轴套-第一齿轮端411-第二齿轮端421-第二齿轮轴套-第二活动件42-第二部分202。即左机身-第一活动件41-第一齿轮轴套-第一齿轮端411-第二齿轮端421-第二齿轮轴套-第二活动件42-右机身。
在本实施例中,通过采用第一齿轮端411和第二齿轮端421直接或者间接啮合,能够实现左右同步效果。其中,第一齿轮端411与第一活动件41为一体式设计,第二齿轮端421与第二活动件42为一体式设计,减少了零件数量,第一活动件和第二活动件能够直接参与啮合,缩短了同步链,减少了中间环节和装配公差,同步效果更好。
根据本申请的一个实施例,铰链组件100还包括第一齿轮43和第二齿轮44。
具体地,第一齿轮43可转动地设于基座10,第一齿轮43与第一齿轮端411啮合。第二齿轮44可转动地设于基座10,第二齿轮44分别与第一齿轮43和第二齿轮端421啮合。
也就是说,在基座10上还设有第一齿轮43和第二齿轮44。第一齿轮43和第二齿轮44位于第一齿轮端411和第二齿轮端421之间。第一齿轮端411与第一齿轮42啮合,第二齿轮端421与第二齿轮44啮合,第一齿轮42与第二齿轮44啮合。即通过设置第一齿轮43和第二齿轮44,实现了第一齿轮端411和第二齿轮端421之间的间接啮合。
其中,第一齿轮端411、第一齿轮43、第二齿轮44和第二齿轮端421可以配合形成同步机构的至少一部分。在第一齿轮端411、第一齿轮43、第二齿轮44和第二齿轮端421转动时,第一齿轮端411、第一齿轮43、第二齿轮44和第二齿轮端421之间互相啮合,能够保证左、右机身转动同步,避免出现歪斜。
可见,本实施例的同步链可大致为第一部分201-第一活动件41-第一齿轮轴套-第一齿轮端411-第一齿轮43-第二齿轮44-第二齿轮端421-第二齿轮轴套-第二活动件42-第二部分202。即左机身-第一活动件41-第一齿轮轴套-第一齿轮端411-第一齿轮43-第二齿轮44-第二齿轮端421-第二齿轮轴套-第二活动件42-右机身。
在本实施例中,通过采用第一齿轮端411、第一齿轮43、第二齿 轮44和第二齿轮端421相互啮合,能够在实现左右同步效果的同时,扩大折叠屏的展开范围,有利于大屏幕设计。
根据本申请的一个实施例,第一齿轮轴套设有第一安装孔412,第一同步轴20的第二端设于第一安装孔412内。在安装时,将第一齿轮轴套套设在第一同步轴20上,实现第一齿轮轴套和第一同步轴20的组装。
第二齿轮轴套设有第二安装孔422,第二同步轴30的第二端设于第二安装孔422。在安装时,将第二齿轮轴套套设在第二同步轴30上,实现第二齿轮轴套和第二同步轴30的组装,具有易于装配的效果。
在本申请的一些具体实施方式中,如图4和图14所示,第一同步轴20为柱形件,第一同步轴20沿其轴向的截面为非圆形,第一安装孔412的内壁面与第一同步轴20的外壁面抵接。
第二同步轴30为柱形件,第二同步轴30沿其轴向的截面为非圆形,第二安装孔422的内壁面与第二同步轴30的外壁面抵接。其中,非圆形为类矩形、异形等。
在本实施例中,通过使第一同步轴20以及第二同步轴30的截面为非圆形,能够避免第一同步轴20与第一安装孔412的内壁面之间发生相对滑动,第二同步轴30与第二安装孔422的内壁面之间发生相对滑动,进而保证第一同步轴20和第一活动件41同步活动,以及第二同步轴30和第二活动件42同步活动。
根据本申请的一个实施例,第一配合部11上设有第一通道,第一同步轴20的第一端可活动地配合在第一通道内,在安装时,第一配合部11通过第一通道从第一同步轴20的第一端套设在第一同步轴20上。
第二配合部12上设有第二通道,第二同步轴30的第一端可活动地配合在第二通道内。在安装时,第二配合部12通过第二通道从第二同步轴30的第一端套设在第二同步轴30上,具有便于装配,结构稳定等优点。
根据本申请的一个实施例,如图3、图9和图13所示,铰链组件100还包括:第一弹性件51和第二弹性件52。
具体地,第一弹性件51沿其伸缩方向的第一端与第一配合部11连接,第一弹性件51沿其伸缩方向的第二端与第一齿轮轴套连接。在第一弹性件51对第一齿轮轴套的反作用力越大时,易于加大第一齿轮 端411和第一齿轮43,或者,第一齿轮端411和第二齿轮端421之间继续啮合旋转的所需的作用力。
第二弹性件52沿其伸缩方向的第一端与第二配合部12连接,第二弹性件52沿其伸缩方向的第二端与第二齿轮轴套连接。同样的,第二弹性件52也能够通过自身的伸缩程度,控制第二齿轮端421和第二齿轮44,或者,第二齿轮端421和第一齿轮端411之间继续啮合旋转所需的作用力。
在本实施例中,第一弹性件51可以与第一配合部11、基座10等配合组成第一阻尼机构的至少一部分。第二弹性件52可以与第二配合部12、基座10等配合组成第二阻尼机构的至少一部分。通过设置第一阻尼机构以及第二阻尼机构,能够提供左、右机身开合过程中的阻尼感。
可选地,第一弹性件51为第一弹簧,第一弹簧套设在第一同步轴20的外周。第二弹性件52为第二弹簧,第二弹簧套设在第二同步轴30的外周。在本实施例中,通过采用第一弹簧和第二弹簧,不仅具有便于套设在第一同步轴20和第二同步轴30上的优点,还具有价格便宜,来源广泛等优点。
根据本申请的一个实施例,如图3、图6和图8所示,第一齿轮轴套具有与第一弹性件51的第二端相对设置的第一配合面,第一配合面设有沿第一同步轴20的转动方向间隔开设置的多个第一凸部413,相邻两个第一凸部413之间形成第一凹部414。
第二齿轮轴套具有与第二弹性件52的第二端相对设置的第二配合面,第二配合面设有沿第二同步轴30的转动方向间隔开设置的多个第二凸部423,相邻两个第二凸部423之间形成第二凹部424。
铰链组件100还包括第一凸轮53和第二凸轮54。
其中,第一凸轮53与第一弹性件51的第二端连接,第一凸轮53具有朝向第一配合面的第三配合面,第三配合面设有沿第一同步轴20的转动方向间隔开设置的第一突出部532和第一凹陷部531,第一突出部532与第一凹部414的形状相对应,第一凹陷部531与第一凸部413的形状相对应,第一凸轮53绕第一同步轴20的轴线可转动以调节第一弹性件51对第一齿轮轴套的预紧力。
第二凸轮54与第二弹性件52的第二端连接,第二凸轮54具有朝 向第二配合面的第四配合面,第四配合面设有沿第二同步轴30的转动方向间隔开设置的第二突出部542和第二凹陷部541,第二突出部542与第二凹部424的形状相对应,第二凹陷部541与第二凸部423的形状相对应,第二凸轮54绕第二同步轴30的轴线可转动以调节第二弹性件52对第二齿轮轴套的预紧力。
其中,基座10可以包括档位支架,第一配合部11和第二配合部12可以设置在档位支架上。左同步摆臂、档位支架、第一同步轴20和第一弹性件51等可以配合形成第一档位机构。档位支架可以通过螺钉固定在中框支架203上。第一同步轴20可以装配在档位支架中。
也就是说,第一齿轮轴套上具有第一凸部413和第一凹部414,即具有凸轮外形。第一凸轮53具有第一突出部532和第一凹陷部531。第一齿轮轴套与第一凸轮53配合,能够实现凹凸互锁。同样的,第二齿轮轴套上也具有第二凸部423和第二凹部424,第二凸轮54具有第二突出部542和第二凹陷部541。第二齿轮轴套与第二凸轮54配合,也能够实现凹凸互锁。通过第一齿轮轴套、第一凸轮53、第二齿轮轴套、第二凸轮54相互配合,能够使左、右机身在完全闭合和完全展开状态时,第一齿轮轴套和第一凸轮53凹凸互锁,第二齿轮轴套和第二凸轮54凹凸互锁,避免左、右机身反向运动。
当施加外力使左、右机身由闭合到展开时,左、右同步摆臂的末端分别在对应的导向支架的凹槽内滑动,第一齿轮轴套的凸轮外形部分对第一凸轮53施加压力并滑移,导致第一弹性件51被压缩。第一弹性件51被压缩的同时会给第一凸轮53提供一个反向推力。同样的,第二弹簧件被压缩的同时会给第二凸轮54提供一个反向推力。即给左、右机身的展开提供阻尼感,并在开合角度内可以实现任意角度的悬停状态。当转动到180°时,左、右机身完全展开。左同步摆臂与第一凸轮53凹凸互锁,右同步摆臂与第二凸轮54凹凸互锁,第一弹性件51和第二弹性件52分别回复至初始状态。当施加外力使左、右机身由展开到闭合时,上述过程反之。
在本实施例中,通过第一弹性件51、第一齿轮轴套上的凸轮外形、第一凸轮53相互配合,以及第二弹性件52、第二齿轮轴套上的凸轮外形、第二凸轮54相互配合,能够实现左、右机身在开合过程中的悬停。
根据本申请的一个实施例,如图3和图12所示,铰链组件100还 包括:限位件55,限位件55分别与第一同步轴20的第二端和第二同步轴30的第二端连接,限位件55上设有第一定位孔551和第二定位孔552,第一同步轴20的第二端穿过第一定位孔551,第二同步轴30的第二端穿过第二定位孔552。
在安装时,可以先将限位件55安装在第一同步轴20和第二同步轴30上,实现第一同步轴20和第二同步轴30的相对位置的限定,进而实现对于第一齿轮端411和第二齿轮端421的相对位置的限定,有利于第一齿轮端411和第二齿轮端421的紧密啮合,或者有利于第一齿轮端411、第一齿轮43、第二齿轮44和第二齿轮端421的紧密啮合。
根据本申请的一个实施例,第一同步轴20的第二端和第二同步轴30的第二端分别设有轴帽,铰链组件100还包括第一卡簧56和第二卡簧57。
其中,第一卡簧56与第一同步轴20的第一端连接,第二卡簧57与第一同步轴20的第一端连接。
在装配时,可以将第一齿轮轴套、第一凸轮53、第一弹性件51和档位支架依次套设在第一同步轴20上,第一同步轴20的第二端可以再通过第一卡簧56固定。
下面以第一同步轴20为例进行说明。
相比于现有的同步轴两端均需要卡簧固定的方案而言,本实施例的第一同步轴20的第二端设有轴帽。在装配时,将第一齿轮轴套等从第一同步轴20的第一端套在第一同步轴20上。由于第一同步轴20的第二端具有轴帽结构,通过轴帽结构即可对第一同步轴20进行限位,无需再在第一同步轴20的第二端再另外安装卡簧进行固定。由此,本实施例中的第一同步轴20只需要一个第一卡簧56,即可实现对于第一同步轴20的限位,具有结构简洁、装配简单、成本较低等优点。
根据本申请的一个实施例,如图6和图7所示,铰链组件100还包括导向盖61、第一摆臂62、第二摆臂63、第一导向支架64和第二导向支架65。
具体地,导向盖61与基座10间隔开分布,导向盖61的第一表面的两端分别设有第一滑槽66和第二滑槽67,第一摆臂62的第一端与第一滑槽66滑动连接。
第二摆臂63的第一端与第二滑槽67滑动连接,第一导向支架64 的第一端与第一摆臂62的第二端活动连接,第二导向支架65的第一端与第二摆臂63的第二端活动连接。
导向盖61、第一摆臂62、第二摆臂63、第一导向支架64和第二导向支架65等可以配合组成导向机构。导向盖61可以通过螺钉固定在中框支架203上。第一导向支架64可作为左导向支架,第二导向支架65可作为右导向支架。左、右导向支架分别与左、右机身固定。第一摆臂62可作为左摆臂,第二摆臂63可作为右摆臂。左、右摆臂上可分别设有滑轨,左摆臂对应的滑轨在第一滑槽66内滑动。右摆臂对应的滑轨在第二滑槽67内滑动。
左摆臂通过销轴与左导向支架连接。右摆臂通过销轴与右导向支架连接。
在左、右机身的展开和闭合的运动过程中,左导向支架在外力的作用下带动左摆臂运动,左摆臂的滑轨在第一滑槽66内滑动。同样的,右导向支架在外力的作用下带动右摆臂运动,右摆臂的滑轨在第二滑槽67内滑动。
第一滑槽66和第二滑槽67均作为导向槽。导向机构通过第一摆臂62和第一滑槽66相配合,以及第二摆臂63和第二滑槽67相配合,能够使左、右机身开合得更加顺滑。
如图1和图10所示,导向机构的数量可以为两个,每个导向机构靠近中框支架203的端部。通过采用两个导向机构,可以保证较强的强度和刚度,左、右机身的连接也更加稳健。
在铰链组件100由折叠到展开的过程中,左摆臂可以使左导向支架和左机身远离铰链中心,右摆臂可以使右导向支架和右机身远离铰链中心。从而使左、右机身在运动过程中始终包裹住屏幕,避免屏幕由折叠到展开后没有机身保护。
总而言之,根据本申请实施例的铰链组件100,通过将第一齿轮端411与第一活动件41设计为一体,将第二齿轮端421与第二活动件42设计为一体,减少了零件数量,使第一活动件41和第二活动件42直接参与啮合,缩短了同步链,减少了中间环节和装配公差,同步效果更好,提高了结构紧凑性,提高了空间利用率。此外,第一同步轴20只需要第一卡簧56固定第一同步轴20的第一端,第一同步轴20的第二端直接通过同步轴帽即可限位。同样的,第二同步轴30也只需要一 个卡簧限位,减少了卡簧所需数量,具有结构简洁、装配简单、成本较低等优点。
本发明还提供了一种电子设备,包括柔性屏幕、第一部分201、第二部分202和上述任一实施例的铰链组件100。其中,第一部分201与第一活动件41连接,第二部分202与第二活动件42连接,柔性屏幕覆盖第一部分201、铰链组件100和第二部分202。
如图1所示,铰链组件100的数量可以为两组,两组铰链组件100可以分别放置于电子设备的折叠轴线方向的两侧,同时铰链组件100可以位于可折叠屏幕的下方。需要说明的是,铰链组件100的数量不限于两组,还可以是多组。
需要说明的是,本发明的实施例仅仅示意说明了U型折叠终端,而三折、多层折叠终端也可以才采用本申请实施例的铰链组件100。
本申请的电子设备200不限于手机产品,还可以为PC、平板等电子消费产品。
需要说明的是,本说明书中的各个实施例均采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似的部分互相参见即可。
尽管已描述了本申请实施例的可选实施例,但本领域内的技术人员一旦得知了基本创造性概念,则可对这些实施例做出另外的变更和修改。所以,所附权利要求意欲解释为包括可选实施例以及落入本申请实施例范围的所有变更和修改。
