技术领域
本申请涉及到电子设备技术领域,尤其涉及到一种支撑组件、保护机构、电机组件及电子设备。
背景技术
目前的可折叠电子设备,例如笔记本电脑、二合一产品等,通常需要手动将其展开,通过开启电源实现可折叠电子设备的开启,并通过键盘输入或者生物指纹登录才能进行使用,该操作过程的步骤较多,时间较长,导致用户体验较差。
随着可折叠电子设备的快速发展,用户对于可折叠电子设备的使用体验提出了越来越高的要求。除了上述的操作过程繁杂造成的用户体验差以外,在手动将可折叠电子设备进行展开或闭合的过程中,操作手感和操作的安全性,可折叠电子设备在展开状态下的稳定支撑,以及闭合状态下的整机厚度等均是影响用户的使用体验的重要因素。
基于此,如何提高可折叠电子设备的用户体验已成为本领域技术人员亟待解决的难题。
发明内容
本申请提供了一种支撑组件、保护机构、电机组件及电子设备,以提高用户的使用体验。
第一方面,提供了一种支撑组件,该支撑组件可应用于可折叠的电子设备。该支撑组件可以包括转轴机构和支撑部。其中,转轴机构可以包括转动组件,该转动组件可与支撑部联动。在具体设置转动组件时,转动组件包括第一固定件、第二固定件、连接件和连杆组件。第一固定件和第二固定件可作为整个转动组件的支撑基座,第一固定件和第二固定件间隔设置,且第一固定件和第二固定件位于连接件的同侧。另外,第一固定件的朝向第二固定件的端面设置有第一滑槽,第二固定件的朝向第一固定件的端面设置有第二滑槽。连接件与连杆组件转动连接,且连杆组件可沿第一滑槽和第二滑槽滑动。在具体设置支撑部时,支撑部包括围绕转轴机构设置的第一支撑板、第二支撑板和第三支撑板,第二支撑板位于第一支撑板和第三支撑板之间,且第二支撑板与第一支撑板和第三支撑板转动连接。第一支撑板的一端与连接件固定连接,这样,在第一支撑板绕转轴机构转动时,连杆组件可沿第一滑槽和第二滑槽滑动,则连接件绕连杆组件转动,从而可使第三支撑板可沿朝向或背离转轴机构的方向滑动。
采用本申请提供的支撑组件,可通过对第一滑槽和第二滑槽的具体形态进行设计,可以实现对连杆组件的运动轨迹的设定。又由于连接件与连杆组件转动连接,则在使连杆组 件沿设定的运动轨迹运动的过程中,可使连接件按照设定的运动轨迹运动。又由于第一支撑板和连接件固定连接,则连接杆按照设定的轨迹运动的过程中,第一支撑板可沿设定的轨迹运动,从而带动第二支撑板转动,并使第三支撑板按照设定的轨迹沿朝向或者背离转轴机构的方向滑动。值得一提的是,在第一支撑板运动并带动第三支撑板沿朝向或背离转轴机构的方向滑动的过程中,第一支撑板、第二支撑板和第三支撑板之间能够形成围绕转轴机构的三角支撑结构,其可有利于提高该支撑部的支撑稳定性,从而提高支撑组件的结构可靠性。
在本申请一个可能的实现方式中,转动组件还可以包括主轴,主轴穿设于第一固定件、连杆组件和第二固定件。其中,主轴可与第一固定件和第二固定件转动连接,并且在主轴相对第一固定件和第二固定件转动的过程中,可以带动连杆组件沿第一滑槽和第二滑槽滑动,从而可带动连接件转动。
另外,转轴机构还可以包括凸轮和辅助支撑机构。在沿主轴的径向方向上,凸轮与主轴相对固定,这样可使主轴在转动的过程中,能够带动凸轮同步转动。在凸轮的表面还可以设置有凸轮滑槽,辅助支撑机构的一端容置于凸轮滑槽,另一端可与第三支撑板连接。在主轴转动的过程中,辅助支撑机构的一端沿凸轮滑槽滑动,以带动第三支撑板沿朝向或背离转轴机构的方向滑动,从而可提高第三支撑板滑动的稳定性,以有利于提高整个支撑部运动的稳定性。
在本申请一个可能的实现方式中,转轴机构可以包括两个转动组件,该两个转动组件间隔设置,且对应每个转动组件设置有一个凸轮。在该实现方式中,辅助支撑机构可以位于两个转动组件之间。在具体设置辅助支撑机构时,辅助支撑机构可以包括第一支撑杆和第二支撑杆,第一支撑杆和第二支撑杆交叉设置,且第一支撑杆和第二支撑杆的中间部位相铰接。另外,第一支撑杆的一端容置于一个凸轮滑槽,另一端与第三支撑板相铰接;第二支撑杆的一端容置于另一个凸轮滑槽,另一端与第三支撑板相铰接。通过将辅助支撑机构的第一支撑杆和第二支撑杆交叉设置,则在第三支撑板沿背离转轴机构的方向滑动的过程中,两个支撑杆绕二者之间的铰接点转动,同时通过对凸轮滑槽的合理设计,可以实现对两个支撑杆的运动轨迹的设计,从而使两个支撑杆能够推动第三支撑板沿背离转轴机构的方向滑动,从而提高第三支撑板滑动的稳定性。
在本申请一个可能的实现方式中,支撑组件还可以包括键盘主体,上述的支撑部可与键盘主体通过转轴机构转动连接。则第三支撑板沿朝向或背离转轴机构的方向的滑动,也可以理解为第三支撑板沿朝向或背离键盘主体的方向滑动。另外,在键盘主体上可以设置有容纳腔,第三支撑板的至少部分可容置于容纳腔,且第三支撑板可在容纳腔内滑动。这样,可在提高第三支撑板的滑动稳定性的同时,还可以使第三支撑板隐藏于键盘主体,以提高支撑组件的外观美观性。
在本申请中,具体设置第三支撑板时,第三支撑板包括固定连接的弧形板段和直板段。其中,弧形板段位于第二支撑板和直板段之间,且第二支撑板与弧形板转动连接。在第三支撑板沿朝向键盘主体滑动时,弧形板段可包覆转轴机构,以避免转轴机构裸露在外,以起到对转轴机构的保护作用,并提高支撑组件的外观美观性。另外,第三支撑板的直板段的至少部分可容置于容纳腔,以为第三支撑板的滑动提供导向的作用。
在本申请一个可能的实现方式中,支撑组件还可以包括主机支撑件,主机支撑件与连接件固定连接。该主机支撑件位于第一支撑板的朝向键盘主体的一侧,且主机支撑件与第 一支撑板的朝向连接件的端部固定连接。该主机支撑件可用于对安装于支撑组件的主机起到支撑的作用。另外,主机支撑件的用于与主机相接触的表面可以设置为弧形面,以提高主机与主机支撑件之间连接的可靠性。
在本申请中,在具体设置连杆组件时,连杆组件可以包括第一连杆和第二连杆。其中,第一连杆位于连接件和第二连杆之间,第二连杆位于第一固定件和第二固定件之间,主轴穿设于第二连杆。在主轴的径向方向上,主轴与第二连杆相对固定,以在主轴转动的过程中,能够带动第二连杆同步转动。另外,第一连杆的一端与连接件转动连接,另一端与第二连杆转动连接,并且第一连杆与第二连杆转动连接的转轴的一端位于第一滑槽,另一端位于第二滑槽。这样,可通过第一连杆与第二连杆转动连接的转轴在第一滑槽和第二滑槽内的滑动,来实现连杆组件沿第一滑槽和第二滑槽内滑动,从而带动连接件转动。
在具体设置连接件时,连接件可以包括本体部,本体部具有相背设置的第一边和第二边。其中,第一边设置有第一安装部、第二安装部和第三安装部,第一安装部和第二安装部间隔设置。本体部包括相背设置的第一面和第二面,第一安装部和第二安装部向背离第二面的方向延伸。第三安装部位于第二面,且第三安装部自第一边向第二边的方向延伸。
在本申请中,转动组件还可以包括中间连杆,中间连杆的数量可以为两个,其中一个中间连杆的一端与第一安装部转动连接,另一端与第一固定件转动连接。另一个中间连接的一端与第二安装部转动连接,另一端与第二固定件转动连接,从而使转动组件的本体可以通过两个中间连杆与两个固定件转动连接。另外,第一连杆的朝向连接件的一端与第三安装部的背离第一边的端部转动连接。又因为第一连杆与第二连杆转动连接的转轴在第一滑槽和第二滑槽内的滑动,则通过对第一滑槽和第二滑槽的轨迹的设计,可以对第一连杆按照设定的运动轨迹运动,从而可实现连接件绕第一连杆按照设定的轨迹转动。
在本申请一个可能的实现方式中,第一支撑板可与连接件的第一面固定连接。从而使第一支撑板能够与连接件按照相同的运动轨迹转动。
在将本申请提供的支撑组件用于电子设备时,不同的用户对于电子设备的展开角度存在个性化的要求。为了满足不同的用户的使用要求,在本申请中,还可以在阻尼力在作用下,使第一支撑板在没有外力的作用下能够悬停在一定的转动位,以使第一支撑板和第三支撑板之间的夹角满足用户的使用要求。具体实施时,转动组件还可以包括第一弹性件,该弹性件设置于第一固定件的背离第二固定件的一侧。第一弹性件沿主轴的轴线产生的弹性作用力可作用于第一固定件。
另外,转动组件还包括第一挤压结构,该第一挤压结构可位于第一固定件与第一弹性件之间。第一挤压结构可套设于主轴,在沿主轴的径向方向上,第一挤压结构与主轴相对固定。第一挤压结构随主轴转动时,第一弹性件的形变量改变。由于主轴与第一固定件转动连接,第一挤压机构与主轴可同步转动,则在主轴转动的过程中,第一挤压机构与第一固定件可发生相对转动。而第一弹性件的形变量改变,其作用于第一挤压结构的弹性作用力改变,从而使第一挤压机构和第一固定件之间的挤压力发生改变,以使第一挤压机构和第一固定件之间由滑动摩擦产生的阻尼力改变,这样可提升用户的手感。另外,当撤销外力时,第一挤压机构和第一固定件可在二者之间产生的阻尼力的作用下停止相对转动,从而使支撑组件悬停在对应的转动位。
在本申请中,为使支撑组件能够稳定的停留在设定的转动位,转动组件还可以包括第二挤压结构,该第二挤压结构位于第一挤压结构与第一固定件之间,第二挤压结构套设于 主轴,主轴与第二挤压结构转动连接。另外,第一弹性件将第一挤压结构压向第二挤压结构,第一挤压结构的朝向第一固定件的端面设置有第一凹槽,第二挤压结构的朝向第一挤压结构的端面设置有第一凸起。可以理解的是,当第一凸起落入第一凹槽时,在主轴的轴向上,第一挤压结构和第二挤压结构的总长度最小,此时第一弹性件的形变量最小,则第一挤压结构和第二挤压结构之间产生的阻尼力较小。而当第一凸起位于第一凹槽之外时,在主轴的轴向上,第一挤压结构和第二挤压结构的总长度最大,此时第一弹性件的形变量最大,第一挤压结构和第二挤压结构之间产生的阻尼力较大。因此,通过对第一凸轮和第二凹槽的设置位置进行调节,可实现对第一挤压结构和第二挤压结构之间产生的阻尼力的调节,从而实现对支撑组件的可悬停的位置的调节。
在本申请一个可能的实现方式中,转动组件还可以包括第二弹性件。该第二弹性件可设置于第二固定件的背离第一固定件的一侧。或者,第二连杆设置有挖空区,第二弹性件可设施与该挖空区。另外,第二弹性件套设于主轴,且第二弹性件的一端与主轴固定连接,另一端与第二固定件固定连接。由于主轴可绕第二固定件转动,则在主轴转动的过程中,第二弹性件可产生绕主轴的轴线方向的弹性作用力。该弹性作用力可在用户转动支撑组件的过程中,为其提供相应的手感,从而提升用户体验。
在本申请中,支撑组件还可以包括键盘主体,支撑部与键盘主体可通过转轴组件转动连接。另外,键盘主体包括转轴连接件、边框组件和按键。转轴连接件可随转轴机构的运动而运动,具体的,转轴机构在运动时,可带动转轴连接件沿朝向或者背离转轴机构的方向运动。在本申请中,按键可为并列设置的多排,每排按键包括多个按键,且每排按键的数量可以相同也可以不同,在本申请中不做具体限定。键盘主体上还设置有按键槽,按键可容置于对应的按键槽。另外,边框组件在具体设置时,其可以包括第一边框、第二边框和横杆。第一边框和第二边框可相对设置,且第一边框和第二边框与转轴连接件固定连接,这样在转轴连接件运动时,可使第一边框和第二边框能够随转轴连接件沿朝向或者背离转轴机构的方向运动。上述的多排按键可以位于第一边框和第二边框之间,并且每排按键可沿第一边框到第二边框的方向排列。每排按键可对应设置有由一个横杆,在第一边框和第二边框对转轴连接件沿朝向或者背离转轴机构的方向运动时,可带动横杆沿每排按键的排列方向运动。并且,按键随横杆的运动可向按键槽内运动,或者向露出于按键槽的方向运动。基于此,可在键盘主体处于使用状态时,使按键朝向露出于按键槽的方向运动至设定行程,以满足用户敲击输入的使用要求。另外,在不使用键盘主体时,可使按键朝向按键槽内运动,从而使按键露出于按键槽的部分较小,从而使整个键盘主体的在厚度方向上的尺寸较小,以有利于实现支撑组件的薄型化设计。
为了使转轴机构能带动转轴连接件转动,在本申请一个可能的实现方式中,转动组件还可以包括第三连杆,该第三连杆与第二固定件滑动连接。在主轴转动的过程中,第三连杆可沿靠近或者背离键盘主体的方向滑动。基于此,可以使转轴连接件与第三连杆固定连接,从而通过第三连杆的滑动,来带动转轴连接件沿靠近或者背离键盘主体的方向滑动。
另外,为了提高第三连杆滑动的稳定性,在本申请中,第二固定件可以设置有滑轨,则第三连杆可容置于滑轨,且可沿滑轨滑动。则该滑轨可为第三连杆的滑动提供导向作用,以有利于提高第三连杆滑动的可靠性。
转动组件还可以设置有第四连杆,该第四连杆与第二固定件固定连接,其连接方式可以但不限于为通过螺钉等紧固件进行紧固联接。另外,第四连杆可设置于滑轨外侧,且将 第三连杆限位于滑轨,从而可避免第三连杆从滑轨中脱落,以提高第三连杆与第二固定件滑动连接的可靠性。
第二方面,提供了一种电子设备,该电子设备可以包括主机以及如第一方面的支撑组件,其中,主机与第一支撑板可拆卸连接。采用本申请提供的电子设备,主机可随第一支撑板沿设定的轨迹运动。另外,在第一支撑板运动并带动第三支撑板沿朝向或背离转轴机构的方向滑动的过程中,第一支撑板、第二支撑板和第三支撑板之间能够形成围绕转轴机构的三角支撑结构,其可有利于提高该支撑部对于主机的支撑稳定性,从而提高电子设备的结构可靠性。
其中,主机可以为包括显示屏和处理器的用户终端,例如平板电脑、手机等。当主机与支撑组件合成一体时,电子设备即为具有上述支撑组件能够实现的折叠、支撑等功能的用户终端。
第三方面,提供了一种保护机构,保护机构包括固定架、第一转轴组件、第二转轴组件、第一转接件和电机连接件。其中,固定架可作为整个保护机构的基座,以起到对整个保护机构的支撑作用。在具体设置固定架时,固定架可以包括第一固定板和第二固定板,第一固定板和第二固定板相对设置,以在第一固定板和第二固定板之间形成安装空间。
第一转轴组件和第二转轴组件均位于安装空间,其中,第一转轴组件可以包括第一轴和第一齿轮件,第一轴的一端固定于第一固定板,另一端固定于第二固定板;第一齿轮件套设于第一轴,第一齿轮件可绕第一轴转动。第二转轴组件包括第二轴和第二齿轮件,第二轴的一端固定于第一固定板,另一端朝向第二固定板延伸。第二齿轮件套设于第二轴,且第二齿轮件可绕第二轴转动。另外,第一转接件位于第二齿轮件与第二固定板之间,且第一转接件套设于第二轴。

采用本申请提供的保护机构,当电机带动转动中心件转动,且作用于第一转接件的扭矩小于第一转接件与转动中心件之间的连接力时,第一转接件与电机连接件连接。此时,第一转接件可随转动中心件同步转动。另外,第一转接件转动可带动第一齿轮件绕第一轴转动,且第一齿轮件转动的扭矩可传递给第二转轴组件。而当作用于第二转轴组件的扭矩通过第一齿轮件传递给第一转接件,且作用于第一转接件的扭矩大于第一转接件与转动中心件之间的连接力时,可使第一转接件与电机连接件的连接断开,以避免该大于第一转接件与转动中心件的连接力的扭矩作用于转动中心件,从而可起到对与转动中心件连接电机的保护作用。
在具体设置第一齿轮件时,沿第一固定板到第二固定板的方向上,第一齿轮件可以包括第一齿轮结构和第二齿轮结构,且第一齿轮结构和第二齿轮结构间隔设置。在具体设置第二齿轮件时,该第二齿轮件可以包括第三齿轮结构,该第三齿轮结构可与第一齿轮结构相啮合。另外,第一转接件可以包括第四齿轮结构,该第四齿轮结构与第二齿轮结构相啮合。这样,当第一转接件带动第一齿轮件绕第一轴转动时,第一齿轮件沿第一固定板到第二固定板的方向滑动,以使第三齿轮结构与第一齿轮结构相脱离。而在第三齿轮结构与第一齿轮结构相脱离时,第一齿轮件转动的扭矩不会再传递到第三齿轮结构,则此时第二齿轮件停止转动。在本申请中,第三齿轮结构与第一齿轮结构相脱离的状态可为电机带动保 护机构展开到最大角度时的状态。
由上述介绍可知第一转接件和转动中心件可连接或断开,则为了实现二者的连接或者断开,可通过对其具体结构的设置来实现。具体实施时,可使第一转接件开设有容置腔,容置腔的开口朝向电机连接件,而转动中心件可插设于容置腔内。第一转接件还可以设置有第一弹性件和滚动件,第一弹性件和滚动件容置于容置腔。第一弹性件的一端与转动中心件相抵接,另一端将滚动件压向容置腔的底壁。
另外,在第一转接件的容置腔的底壁还可以设置有凹槽,这样,当滚动件容置于凹槽时,第一转接件与转动中心件处于连接的状态,在此状态下,第一转接件可随转动中心件同步转动。而当滚动件脱离凹槽时,第一转接件与转动中心件的连接断开,在此状态下第一转接件转动扭矩不能传递至转动中心件,则转动中心件停止转动。
在本申请一个可能的实现方式中,第二齿轮件的朝向第一固定板的端部还可以设置有第一止位部,该第一止位部设置有缺口。第二转轴组件还可以包括固定销和滑动销,固定销和滑动销位于第二齿轮件的朝向第一固定板的一侧。固定销套设于第二轴,且固定销与第二轴转动连接。滑动销设置于固定销与第一止位部之间,滑动销的朝向固定销的一端与固定销滑动连接,滑动销背离固定销的一端设置有第二止位部,第二止位部可插设于缺口。在滑动销的第二止位部插设于缺口时,第二齿轮件转动可带动滑动销转动,从而带动固定销转动。
在本申请一个可能的实现方式中,在滑动销与第二齿轮件之间还可以设置有垫片,滑动销和第二齿轮件均与垫片相抵接。这样,可在滑动销与第二齿轮件发生相对转动时,能够在二者之间产生一定的阻尼力,以有利于提升用户的使用体验。
为了实现第一齿轮件沿第一轴的滑动,在本申请中,可在第一齿轮件上设置导向槽结构,该导向槽结构可位于第一齿轮结构和第一固定板之间。导向槽结构可以设置有导向槽,该导向槽可以设置于螺旋状。另外,固定销可设置有导向结构,该导向结构可插接于导向槽。这样,在固定销转动时,导向结构可在导向槽内滑动。而导向槽可设置为螺旋状态,则导向结构在导向槽内滑动的过程中,可以带动第一齿轮件沿第一轴的轴向滑动,从而使第三齿轮和第一齿轮相脱离。另外,在固定销转动的过程中,滑动销可以随第一齿轮件滑动而滑动,并且滑动销可与第一齿轮件的滑动方向相反。
在本申请一个可能的实现方式中,第一转轴组件还可以包括助力机构,该助力机构的一端可与第一齿轮件固定连接,另一端可与第一轴固定连接。这样,通过对助力机构进行合理的设计,以使助力机构可用于为第一齿轮件沿第一轴的滑动提供助力,从而提升第一齿轮件滑动的可靠性。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述。
本申请实施例提供了一种键盘组件,为了方便理解本申请实施例提供的键盘组件,下面首先说明一下其应用场景。该键盘组件可应用于电子设备,例如用于可折叠的电子设备,示例性的,可以但不限于为二合一产品等。二合一产品通常包括主机1和键盘组件2,可参照图1,图1为本申请一实施例提供的一种传统的二合一产品。在该实施例中,主机1与键盘组件2为可拆卸连接,在与键盘组件2分离后,主机1仍能够作为一个独立的电子设备使用,例如主机1可以是平板电脑。键盘组件2除了包括能够实现键盘功能的键盘主体201,还具有作为支撑结构的支撑部202,以能够起到对主机1的支撑作用,从而便于用户的使用。例如,键盘组件2可以是与平板电脑配套使用的键盘配件,既能够支撑平板电脑,又能够作为键盘使用。
可以理解的是,在将主机1安装于键盘组件2后,可通过键盘组件2的键盘主体201和支撑部202的相对转动来实现该二合一产品的展开以及闭合。而键盘主体201和支撑部202之间的相对转动可通过转轴机构3的设置来实现。由图1可以看出,键盘主体201和支撑部202可分别位于转轴机构3的两侧,且可分别与转轴机构3转动连接。
目前,为了减少用户在启动类似二合一产品的可折叠电子设备的过程中的展开、开启电源以及登录等的操作步骤,自动开合的概念在该领域被提出。由于键盘组件2的键盘主体201和支撑部202可通过转轴机构3来实现相对转动,因此,用于实现自动开合功能的自动开合装置可设置于转轴机构3。自动开合装置中通常包括电机,以通过电机带动转轴机构3的转动,来实现键盘主体201和支撑部202的相对转动。
但为了顺应目前电子设备越来越轻薄的发展趋势,键盘组件2中为转轴机构3预留的设置空间越来越有限。在此基础上,若将自动开合装置设置于转轴机构3,其就要求自动开合装置中的例如电机等结构的尺寸较小。而电机的尺寸太小,其为转轴机构3的转动提供的扭矩受到限制。
由上述介绍可知,在二合一产品中,主机1和键盘组件2为可拆卸连接的结构形式,而通常情况下,主机1的重量大于键盘组件2的重量。因此,在二合一产品展开到一定角度时,键盘组件2对主机1的支撑力不足,在二合一产品的运动过程会出现晃动,甚至会造成转轴机构3的损坏。
另外,由于用户对于二合一产品的使用角度存在个性化的要求,如果在通过电机带动 二合一产品进行展开以及闭合的过程中,人为干预该过程,在电机提供的扭矩不足时,会造成自动开合装置中的电机或者其它机构件的损坏。
本申请提供的转轴机构旨在解决上述问题,以通过在转轴机构的自动开合装置中设置保护机构,以可在人为干预等场景下,对自动开合装置起到保护的作用,从而实现键盘组件的安全可靠的自动开合功能,以延长其使用寿命。另外,通过在转轴机构中设置转动组件,实现键盘组件的展开及闭合角度的无级调节和任意角度悬停。为了便于对本申请提供的转轴机构,以及应用有该转轴机构的键盘组件和电子设备进行了解,接下来结合具体实施例对其进行详细说明。
应当理解的是,以下实施例中所使用的术语只是为了描述特定实施例的目的,而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样,单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式,除非其上下文中明确地有相反指示。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此,在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其它一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例,而是意味着“一个或多个但不是所有的实施例”,除非是以其它方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”,除非是以其它方式另外特别强调。
参照图2,图2为本申请一实施例提供的转轴机构的应用场景示意图。在图2中展示了一种可进行折叠的电子设备,该电子设备包括主机1和键盘组件2。其中,主机1和键盘组件2可拆卸连接。在本申请中,主机1为具有完整结构和功能的产品,该主机1在与键盘组件2拆卸后,仍能够作为一个独立的电子设备进行使用。本申请的主机1可以但不限于包括显示屏、电池模块以及计算存储模块等。另外,主机1还可以设置有与外部设备进行匹配的触点或者连接器接口,例如,弹簧针(pogo pin),USB、Type-A或者Type-C等连接接口,以实现主机1与外部设备之间的有线连接。又或者主机1可以具有蓝牙以及wifi等功能模块,以实现其与外部设备之间的无线连接。在本申请中,不对主机1的类型进行具体的限定,其可以但不限于为平板电脑或者掌上电脑(personal digital assistant,PDA)等。
参照图3a,图3a为本申请一实施例提供的键盘组件2的结构示意图。在该实施例中,键盘组件2处于展开的状态(即支撑部202远离键盘主体201,键盘主体201处于暴露给用户的状态),其中,键盘组件2包括键盘主体201和支撑部202,键盘主体201可为主机1提供键盘输入的功能。另外,在键盘主体201内还可以设置有控制电路、电池或者一些传感器(例如红外传感器、超声波传感器或者指纹传感器等)等,其中,控制电路的设置可为键盘主体201提供电路控制的功能,传感器的设置可提供信号触发等功能。另外,键盘主体201中的电池可在无外部供电时用于维持键盘主体201的正常的工作状态。
由前述实施例可知,键盘主体201和支撑部202的相对转动可通过转轴机构3实现,可继续参照图3a,在该实施例中,键盘组件2还包括转轴机构3,键盘主体201可与转轴机构3相连接。
在本申请中,键盘组件2的支撑部202包括第一支撑板2021、第二支撑板2022、第三支撑板2023,该第一支撑板2021、第二支撑板2022和第三支撑板2023围绕转轴机构3 设置。其中,第一支撑板2021可起到对如图2中所示的主机1的支撑的作用。为了能够对安装于键盘组件2的主机1与第一支撑板2021之间进行固定,在本申请一个可能的实施例中,可以在第一支撑板2021中设置有第一磁性元件(图3a中未示出),并在主机1的对应的位置设置有第二磁性元件,第一磁性元件与第二磁性元件可相吸附。在本申请中,第一磁性元件可以为带有磁性的元件,也可以为本身不带有磁性,但是能够被带有磁性的元件吸附的元件。相类似的,第二磁性元件可以为带有磁性的元件,也可以为本身不带有磁性,但是能够被带有磁性的元件吸附的元件。只要能够第一磁性元件与第二磁性元件的相互吸附固定即可。
继续参照图3a,第一支撑板2021具有相背设置的第一边2021a和第二边2021b,其中,第一支撑板2021的第一边2021a朝向转轴机构设置,该第一边2021a可与一主机支撑件4固定连接,该第一支撑板2021可绕转轴机构转动。可一并参照图2和图3a,主机支撑件4可用于对主机1起到支撑的作用,另外,主机支撑件4可设置有一个弧面,主机1在安装于该主机支撑件4后,主机1的边框可与该弧面相卡接,以实现主机支撑件4与主机1的边框的贴合及固定,其有利于实现主机1与第一支撑板2021之间的固定,从而降低主机1从第一支撑板2021上脱落的风险。可以理解的是,在本申请中,主机支撑件4还可以设置有连接器接口或者触点等,且该连接器接口或者触点可通过引线引至键盘主体201内的控制电路。这样,在主机1安装于键盘组件2时,可将主机1的触点或者连接器接口,与主机支撑件4上对应的触点或者连接器接口进行连接,从而实现主机1与键盘组件2之间的电连接,其可通过键盘主体201实现对主机1的操作以及控制。值得一提的是,在本申请中,用于连接主机支撑件4和键盘主体201的控制电路的引线可隐藏于转轴机构3中,以对该引线起到保护的作用。
参照图3b,图3b为本申请一实施例提供的键盘组件的剖面图。在本申请中,第二支撑板位于第一支撑板2021和第三支撑板2023之间,第二支撑板2022可以包括相背设置的第一边2022a和第二边2022b,第二支撑板2022的第一边2022a与第一支撑板2021的背离键盘主体201的表面相铰接,则第二支撑板2022与第一支撑板2021可相对转动。另外,第三支撑板2023包括相背设置的第一边2023a和第二边2023b,第二支撑板2022的第二边2022b与第三支撑板2023的第一边2023a相铰接。
可继续参照图3b,在图3b所示的实施例中,键盘组件2处于展开的状态,第一支撑板2021、第二支撑板2022和第三支撑板2023的围绕转轴机构3设置的部分围成一个三角支撑结构。这样,在键盘组件2展开以及闭合(即支撑部202靠近键盘主体201,键盘主体201被支撑部202的一部分遮盖)的过程中,该三角支撑结构能够实现对如图2中所示的主机1进行稳定的支撑,并且还可使键盘组件2的支撑部202和键盘主体201之间的相对转动过程较为平稳,从而可使键盘组件2的结构较为可靠。
参照图4a,图4a为本申请图2提供的电子设备处于闭合状态时的结构示意图。由图4a可以看出,在电子设备处于闭合的状态时,主机1与键盘主体201相贴合,第二支撑板2022的至少部分和第一支撑板2021覆盖于主机1,以对主机1起到保护的作用。另外,在本申请中,第三支撑板2023包括弧形板段20231和直板段20232,其中,弧形板段20231的弧度可以根据转轴机构3的外形轮廓进行设计,以在电子设备处于闭合状态时,使弧形板段20231能够包覆转轴机构3,以对转轴机构3起到保护的作用,并且能够提高键盘组件2的外观美观性。
采用本申请提供的电子设备,当需要将其由闭合状态展开时,可对主机1和第一支撑板2021施加背离键盘主体201的作用力F。可参照图4b至图4e,图4b至图4e为电子设备展开到不同角度时的结构示意图。由图4b至图4e可以看出,在电子设备展开的过程中,第一支撑板2021可带动第二支撑板2022相背离键盘主体201的方向转动,而第二支撑板2022转动的同时,可带动第三支撑板2023向背离键盘主体201的方向移动,以使第三支撑板2023与转轴机构3分离。
另外,可继续参照图4a至图4e,在电子设备展开的过程中,第一支撑板2021、第二支撑板2022和第三支撑板2023围绕转轴机构3的部分围成一个三角支撑结构,其可有效增加该电子设备运动的稳定性。可以理解的是,在该电子设备由展开状态到闭合的过程中,第一支撑板2021、第二支撑板2022和第三支撑板2023均朝向键盘主体201运动,在该过程中,三角支撑结构同样可对于电子设备的运动提供稳定的支撑。
参照图5,图5为本申请提供的键盘组件处于闭合状态时的截面结构示意图。由上述实施例的介绍可以知道,在键盘组件由展开状态运动至闭合状态的过程中,第三支撑板2023沿朝向键盘主体201的方向运动。在本申请中,键盘主体201可以设置有一容纳腔2011,该容纳腔2011的开口朝向第三支撑板2023开设。这样,可在键盘组件2处于图5所示的闭合状态时,可使第三支撑板2023的直板段20232的至少部分容置于容纳腔2011内,以提高键盘组件2的外观的一体化程度。另外,在本申请一些实施例中,还可以使第三支撑板2023的如图3b所示的第二边2023b始终位于容纳腔2011内,且第三支撑板2023可在容纳腔2011内滑动,从而使该容纳腔2011可为第三支撑板2023的滑动提供导向作用。为了提高第三支撑板2023运动的稳定性,在本申请还有一些实施例中,可以在容纳腔2011的侧壁上设置滑轨(图5中未示出),同时在第三支撑板2023上设置滑块结构(图5中未示出),并使滑块结构能够沿滑轨运动,以减少第三支撑板2023在运动过程中的晃动,从而提高整个键盘组件2的运动稳定性。
由上述实施例的介绍可以知道,转轴机构3在键盘组件2由展开状态到闭合状态,以及由闭合状态到展开状态的运动过程中起着至关重要的作用。为了能够对本申请提供的键盘组件2的运动的实现方式进行理解,接下来结合附图对转轴机构3的具体设置方式进行详细说明。
可以理解的是,为了能够使键盘组件2的键盘主体201和支撑部202可以保持在任意折叠角度,以满足用户的个性化的使用要求,通常可在转轴机构3中设置转动组件,以在键盘组件2进行折叠模式切换的过程中,使转动组件能够为整个键盘组件2提供可靠的阻尼力,从而实现对主机1的稳定支撑。在本申请中,键盘主体201和支撑部202之间的折叠角度是指在键盘组件2由展开状态到闭合状态,以及由闭合状态到展开状态的过程中,键盘主体201的朝向支撑部202的表面和支撑部202的朝向键盘主体201的表面之间的夹角。
参照图6a,图6a为本申请一实施例提供的转动组件的结构示意图。在图6a中展示了键盘组件2处于闭合状态时,转动组件301的结构示意图。另外,参照图6b,图6b展示了键盘组件2处于展开状态时,转动组件301的结构示意图。
可一并参照图6a和图6b,在该实施例中,转动组件301可以包括连接件3011、第一固定件3012和第二固定件3013。其中,第一固定件3012和第二固定件3013可与上述的如图5所示的键盘主体201固定连接,其连接方式可以但不限于为通过螺钉等紧固件紧固 连接。另外,第一固定件3012和第二固定件3013可作为整个转动组件301的支撑件,第一固定件3012和第二固定件3013间隔设置,转动组件301的其它结构均可以通过直接或者间接的方式与第一固定件3012和第二固定件3013连接。

可一并参照图6a、图6b和图7,在本申请中,第一固定件3012和第二固定件3013位于连接件3011的同侧。转动组件301还可以包括连杆组件,该连杆组件包括中间连杆3014,该中间连杆3014为两个,第一固定件3012的朝向连接件3011的一侧表面设置有第一开槽30121,第二固定件3013的朝向连接件3011的一侧表面设置有第二开槽30131。中间连杆3014包括相背设置的第一端和第二端,其中一个中间连杆3014的第一端安装于第一安装部30112的第一安装槽内,该中间连杆3014的第二端安装于第一固定件3012的第一开槽30121内。另外,中间连杆3014的第一端与第一安装槽的槽壁通过第一转轴3015a转动连接,中间连杆3014的第二端与第一固定件3012的第一开槽30121通过第二转轴3015b转动连接。其中,为了实现中间连杆3014的第一端与第一安装槽的槽壁的转动连接,可使第一转轴3015a与第一连杆的第一端固定连接,且第一转轴3015a与第一安装槽的槽壁转动连接,其转动连接的方式,可通过在第一安装槽的两个相对的槽壁上开设安装孔,并使中间连杆3014的两个端部分别插设于一个安装孔。在本申请另外一些实施例中,还可以使第一转轴3015a与第一安装槽的槽壁固定连接,并使中间连杆3014的第一端可绕第一转轴3015a转动。另外,在该实施例中,中间连杆3014的第二端与第一固定件3012的第一开槽30121的槽壁可通过第二转轴3015b转动连接,第二转轴3015b可以但不限于为销轴。值得一提的是,在本申请中,两个结构件之间的转动连接方式均可参照上述中间连杆3014的第一端与第一安装槽的槽壁通过第一转轴3015a转动连接的方式进行设置,在以下各实施例中不进行赘述。
相类似的,另一个中间连杆3014的第一端可安装于连接件3011的第二安装部30113的第二安装槽内,并与第二安装槽的槽壁通过第一转轴3015a转动连接。该中间连杆3014的第二端可安装于第二固定件3013的第二开槽30131内,并与第二开槽30131的槽壁通过第二转轴3015b转动连接。另外,在该实施例中,中间连杆3014的第二端与第二固定件3013的第二开槽30131的槽壁可通过第二转轴3015b转动连接,该第二转轴3015b可 以但不限于为销轴。
可继续参照图6a、图6b和图7,在本申请中,连杆组件还可以包括第一连杆3016和第二连杆3017,第一连杆3016包括相背设置的第一端和第二端,第一连杆3016的第一端可安装于连接件3011的第三安装部30114,且第一连杆3016的第一端位于两个连接臂301141之间,且第一连杆3016的第一端通过第三转轴3015c与两个连接臂301141转动连接。另外,第一连杆3016的第二端通过第四转轴3015d与第二连杆3017转动连接。其中,第二连杆3017的用于与第一连杆3016连接的一端可以设置有第三开槽30171,第一连杆3016的第二端可安装于该第三开槽30171,且第一连杆3016的第二端通过第四转轴3015d与第三开槽30171的槽壁转动连接,以使第一连杆3016与第二连杆3017形成的连接结构较为紧凑。
另外,在第一固定件3012的朝向第二固定件3013的一侧端面设置有第一滑槽(图7中未示出),在第二固定件3013朝向第一固定件3012的一侧端面设置有第二滑槽30132。第三转轴3015c的一端插设于第一滑槽,且可沿第一滑槽滑动,第三转轴3015c的另一端可插设于第二滑槽30132,且可沿第二滑槽30132滑动。其可理解为,连杆组件可沿第一滑槽和第二滑槽30132滑动。
在本申请中,通过对第一滑槽和第二滑槽30132的具体形态进行设计,可以实现对第三转轴3015c的运动轨迹的设定。又由于第一连杆3016的第一端通过第三转轴3015c与连接件3011转动连接,则在使第三转轴3015c沿设定的运动轨迹运动的过程中,可使第一连杆3016的第二端与连接件3011的连接处按照设定的运动轨迹运动。
示例性的,可参照图8a,图8a为图6a中所示的转动组件301的A-A处的剖面图。在图8a中展示了键盘组件2处于闭合状态时,即键盘主体201的朝向支撑部202的表面和支撑部202的朝向键盘主体201的表面之间的夹角近似为0°时,第三转轴3015c在第二滑槽30132中的位置。在图8a所示的状态下,第三转轴3015c位于第二滑槽30132的最高点。另外,在将该转动组件301用于键盘组件2时,在图8a所示的状态下,第三转轴3015c位于第二滑槽30132的距键盘主体201的一端。
在键盘组件2由闭合状态向展开状态运动的过程中,第三转轴3015c可沿第二滑槽30132滑动。可参照图8b,图8b展示了键盘组件2处于闭合状态到展开状态的中间某一状态时,第三转轴3015c在第二滑槽30132中的位置。在图8b所示的状态下,键盘主体201的朝向支撑部202的表面和支撑部202的朝向键盘主体201的表面之间的夹角近似可为45°。通过对比图8a和图8b可以看出,键盘组件2在展开的过程中,第三转轴3015c沿第二滑槽30132朝向键盘主体的方向滑动。
键盘组件在图8b所示的状态下继续展开时,可参照图8c,图8c展示了键盘主体201的朝向支撑部202的表面和支撑部202的朝向键盘主体201的表面之间的夹角近似可为110°时,第三转轴3015c在第二滑槽30132内的位置。又可以参照图8d,图8d展示了键盘主体201的朝向支撑部202的表面和支撑部202的朝向键盘主体201的表面之间的夹角最大(例如可近视为130°)时,第三转轴3015c在第二滑槽30132内的位置,此时,第三转轴3015c位于第二滑槽30132的距键盘主体201最近的一端。一并图8a至图8d可以知道,在本申请中,通过对第二滑槽30132的具体形式的设计,即可以实现对连接件3011的运动轨迹的设置。
可继续参照图6a、图6b和图7,在本申请中,转动组件301还可以包括主轴3018, 主轴3018可依次穿设于第一固定件3012、第二连杆3017和第二固定件3013。其中,主轴3018与第一固定件3012和第二固定件3013转动连接,则主轴3018可相对第一固定件3012和第二固定件3013转动。另外,在主轴3018的径向方向上,第二连杆3017与主轴3018相对固定,则第二连杆3017可与主轴3018绕主轴3018的轴线同步转动。在本申请一个可能的实施例中,为了将第二连杆3017与主轴3018在径向方向上相对固定,可以在第二连杆3017上设置异形孔,示例性的可以但不限于为D形孔。同时使主轴3018的穿设于第二连杆3017的部分的截面也设置为可与异形孔相匹配的异形截面,以实现第二连杆3017和主轴3018在径向方向上的限位。
另外,主轴3018的位于第二固定件3013的背离第一固定件3012的一端还可以设置有止挡部30181,以实现对主轴3018的沿轴向方向的限位,减小主轴3018沿轴向方向的窜动,从而提高整个转动组件301的运动稳定性。
在本申请中,为了能够使转动组件301能够在整个转轴机构运动的过程中为其提供对应转动位下的阻尼力,以使转轴机构能够保持在对应的转动位,可以继续参照图7,在本申请一个可能的实施例中,还可使转动组件301设置有弹性件3019,该弹性件3019在受压时可积蓄弹性作用力。如图7所示,该弹性件3019可以设置于第一固定件3012的背离第二固定件3013的一侧。在本申请中不对弹性件3019的具体设置形式进行限定,其示例性的可包括弹性碟片,该弹性碟片可为一个或者多个。当弹性件3019包括多个弹性碟片时,该多个弹性碟片可相叠置设置。另外,可参照图7,弹性件3019可套设于主轴3018,在该实施例中,当弹性件3019受压时,其会产生沿主轴3018的轴向方向的弹性作用力。
另外,为了避免弹性件3019从主轴3018上脱落,还可以在弹性件3019的背离第一固定件3012的一侧设置限位件3020,该限位件3020示例性的可为螺母,该限位件3020套设于主轴3018,且对弹性件3019的沿主轴3018的轴向方向进行限位。除此之外,在本申请中,为了能够对弹性件3019施加有效的作用力,还可以设置有一组垫片3021,该一组垫片3021套设于主轴3018,弹性件3019设置于该一组垫片3021之间。另外,还可以使垫片3021的外圈直径大于或等于弹性件3019的外圈直径。限位件3020可与位于弹性件3019的背离第一固定件3012的一侧的垫片3021相抵接。
值得一提的是,在本申请中,弹性件3019沿主轴3018的轴向可发生形变,且弹性件3019发生形变产生的弹性作用力可作用于第一固定件3012,以在第一固定件3012与弹性件3019之间产生摩擦力,该摩擦力可阻碍主轴3018的转动。又由于第二连杆3017可与主轴3018同步转动,而第二连杆3017可带动连接件3011转动,连接件3011又与固定于如图3b所示的第一支撑板2021的主机支撑件4固定连接。因此,当第二连杆3017随主轴3018的转动被阻碍时,第一支撑板2021的运动会受到阻碍,这样即将弹性件3019产生的弹性作用力转化为阻碍转轴机构转动的阻尼力。
可以理解的是,主机1可固定于第一支撑板2021,当主机1随第一支撑板2021转动的过程中到达某一转动位时,若主机1的重力产生的扭矩与上述转轴机构的阻尼力产生的扭矩相等,则在没有外力的作用下,第一支撑板2021即可悬停在该对应的转动位。
由于转轴机构在任何转动位下所需要的阻尼力不同,而该阻尼力的改变可通过弹性件3019产生的弹性作用力的改变来实现,弹性件3019的弹性作用力的改变可通过其形变的改变来实现。在本申请一个可能的实施例中,为了能够使弹性件3019在不同的转动位下具有对应的形变,可在第一固定件3012与弹性件3019之间设置凸轮接触面。具体实施时, 可继续参照图7,在弹性件3019和第一固定件3012之间设置有第一挤压结构3022,该第一挤压结构3022套设于主轴3018,且弹性件3019可将第一挤压结构3022压向第一固定件3012,以使第一挤压结构3022在弹性件3019的弹性作用力下与第一固定件3012相抵接。另外,在沿主轴3018的径向方向上,第一挤压结构3022与主轴3018相对固定,则该第一挤压结构3022可随主轴3018同步转动。其中,可以在第一挤压结构3022上设置异形孔,示例性的可以但不限于为D形孔。同时使主轴3018的穿设于第一凸轮机构3022的部分的截面也设置为可与异形孔相匹配的异形截面,以实现第一挤压结构3022和主轴3018在径向方向上的限位。
参照图9,图9展示了本申请一实施例提供的第一挤压结构的结构示意图。在第一挤压结构3022的朝向第一固定件3012的端面设置有第一凹槽30221,该第一凹槽30221为多段,例如图9中所示的4段。另外,第一凹槽30221可呈弧形设置,并且该多段第一凹槽30221所在的圆形的半径可不同。为了使第一挤压结构3022与第一固定件3012的端面相配合,在本申请中,第一固定件3012的朝向第一挤压结构3022的端面可以设置有第一凸起(图中未示出),该第一凸起也为多段,且该多段第一凸起与上述的多段第一凹槽30221一一对应的设置。可以理解的是,在本申请另外一些实施例中,第一凹槽30221也可以设置于第一固定件3012的朝向第一挤压结构3022的端面,同时第一凸起可设置于第一挤压结构3022的朝向第二固定件的端面。
当相对应设置的第一凸起落入第一凹槽30221内,以使第一凹槽30221与第一凸起相配合卡接时,第一挤压结构3022与第一固定件3012在沿主轴3018的轴向方向上的总长度最小,此时,弹性件3019受到的挤压力最小,则弹性件3019的形变量最小,从而使其产生的弹性作用力最小,则第一挤压结构3022与第一固定件3012之间的摩擦力最小。当第一挤压结构3022与第一固定件3012相对转动后,第一凹槽30221与第一凸起相错时,第一挤压结构3022与第一固定件3012在沿主轴3018的轴向方向上的总长度增大,从而使弹性件3019的形变量增加,以积蓄弹性作用力,在该弹性作用力下,第一挤压结构3022与第一固定件3012之间的摩擦力增大,从而使转轴机构的阻尼力增大。
值得一提的是,在本申请中,可通过对第一凹槽30221和第一凸起进行合理的设计,以使转轴机构3的阻尼力在对应键盘组件2处于闭合状态时最大,以使键盘组件2能够稳定的维持在该闭合状态。
可继续参照图7,在本申请中,转动组件301中还可以设置有弹性件3023,该弹性件3023示例性的可为扭簧。另外,参照图10,图10为与图6b对应的转动组件301的另一角度下的结构示意图。由图10可以看出,第二连杆3017可设置有挖空区30172,弹性件3023可隐藏于该挖空区30172。在该实施例中,弹性件3023可套设于主轴3018。又由于主轴3018与第一固定件3012和第二固定件3013可相对转动,且第二连杆3017可与主轴3018同步转动,则在本申请中,可使弹性件3023的一端固定于第一固定件3012或第二固定件3013,另一端固定于第二连杆3017或主轴3018。这样,在第二连杆3017随主轴3018转动的过程中,可使弹性件3023产生弹性变形,从而产生绕主轴方向的弹性作用力。基于此,通过合理设计,可使弹性件3023产生的弹性作用力为第二连杆3017和主轴3018的转动提供辅助力,从而可在对如图7中所示的连接件3011施加较小的作用力时,即可带动第二连杆3017和主轴3018转动,其可提高用户对应用有该转动组件301的键盘组件2进行开合操作的舒适性。
可继续参照图7,转动组件301还可以包括第三连杆3024,该第三连杆3024可沿第二固定件3013滑动。另外,可参照图10,第二固定件3013的背离如图7中所示的第二开槽30131的一侧设置有滑轨30133,第三连杆3024可容置于该滑轨30133,且可沿滑轨30133滑动。
在本申请一些实施例中,为避免第三连杆3024从滑轨30133中脱落,可继续参照图7和图10,转动组件301还可以包括第四连杆3025,该第四连杆3025的至少部分位于第三连杆3024的背离第二开槽30131的一侧,且第四连杆3025与第二固定件3013固定连接。从而通过第四连杆件3025将第三连杆3024限位于滑轨30133内,以提高第三连杆3024运动的可靠性。
另外,在转动组件301转动的过程中,为了实现第三连杆3024在滑轨30133内的滑动,由图7可以看出,第三连杆3024的朝向第二固定件3013的一侧具有连接部30241。由于转动组件301的其它结构可随主轴3018转动而转动,因此,在本申请中,可将第三连杆3024通过连接部30241与主轴3018相连接。具体实施时,可参照图11a,图11a为图10中的B-B处的剖面图。由前述实施例的介绍可以知道,主轴3018的位于第二固定件3013的背离第一固定件3012的一侧设置有止挡部30181。可一并参照图7和图11a,在止挡部30181的朝向第三连杆3024的端面可设置有轨迹槽301811,第三连杆3024的连接部30241可插设于该轨迹槽301811内。这样,在主轴3018转动的过程中,第三连杆3024的连接部30241可沿轨迹槽301811滑动。
可以理解的是,通过对轨迹槽301811进行合理的设计,可以实现对第三连杆3024的运动轨迹的设计,示例性的,可以在转动组件301处于图11a所示的展开状态时,使第三连杆3024能够隐藏于第二固定件3013。另外,可参照图11b,图11b为转动组件301处于闭合状态时,第三连杆3024与止挡部30181之间的相对位置关系。在转动组件301处于图11b所示的闭合状态时,第三连杆3024可由第二固定件3013伸出。例如,在将该转动组件301用于如图3a所示的键盘组件2时,键盘组件2由展开状态到闭合状态的过程中,第三连杆3024可沿朝向键盘主体201的方向滑动。相反的,当键盘组件2由闭合状态到展开状态的过程中,第三连杆3024可沿远离键盘主体201的方向滑动。在本申请另外一些实施例中,也可以在将该转动组件301用于键盘组件2时,键盘组件2由展开状态到闭合状态的过程中,第三连杆3024可沿背离键盘主体201的方向滑动。相反的,当键盘组件2由闭合状态到展开状态的过程中,第三连杆3024可沿朝向键盘主体201的方向滑动。
由前述实施例的介绍我们知道,键盘组件2的键盘主体201可用于实现键盘输入的功能。则键盘主体201可设置有按键2012。参照图12,图12为本申请一个可能的实施例提供的键盘主体201的局部结构示意图。键盘主体201还可以包括键盘盖板2013,该键盘盖板2013可对键盘主体201的内部结构起到保护的作用,按键2012可由键盘盖板2013露出。由于在通常情况下,按键2012可凸出于键盘盖板2013的表面设置,以便于通过敲击按键2012来实现其功能。但是,在键盘组件2处于闭合状态时,按键2012处于未使用的状态,此时不需要按键2012凸出键盘盖板2013的表面。基于此,本申请提供了一种能够使键盘主体201上的按键2012随转轴机构的转动实现升降的方案,以在键盘组件2处于展开状态时,按键2012升起至凸出于键盘主体201的键盘盖板2013的表面。而在键盘组件2处于闭合状态时按键2012降落,并隐藏于键盘主体201,从而减小键盘组件2在闭合状态下的厚度,以顺应电子设备的薄型化设计的要求,也避免了由于闭合状态下键盘主体 201与电子设备的显示屏贴合而造成的显示屏留痕,提升用户的使用体验。
在具体实施时,参照图13a,图13a展示了本申请提供的键盘主体201的整体结构示意图。在图13a中省略了图12中所示的按键2012以及按键盖板2013等结构,以便于展示转轴机构3与键盘主体201之间的连接关系。由图13a可以看出,键盘主体201的靠近转轴机构3的端部可以设置有转轴连接件2014。该转轴连接件2014可以但不限于呈长条结构设置,且转轴连接件2014的长度方向可与转动组件301的主轴3018的轴向相同。
由前述实施例对转轴机构3的转动组件301的介绍可以知道,转动组件301包括可沿朝向或者背离键盘主体201的方向滑动的第三连杆3024。则在本申请中,可将转轴连接件2014与第三连杆3024固定连接,从而在第三连杆3024滑动的过程中,带动转轴连接件2014沿朝向或者背离转轴机构3的方向移动。可以理解的是,在本申请中,可在第三连杆3024沿朝向键盘主体201的方向滑动时带动转轴连接件2014沿背离转轴机构3的方向移动,而在第三连杆3024沿背离键盘主体201的方向滑动时带动转轴连接件2014沿朝向转轴机构3的方向移动。
值得一提的是,在本申请中,为了提高转轴连接件2014运动的稳定性,可以在转轴机构3中设置多个转动组件301。例如在图13a中所示的实施例中,转轴机构3可以设置有两个转动组件301,该两个转动组件301可设置于转轴机构3的长度方向的两个端部。这样,两个转动组件301的第三连杆3024可均与转轴连接件2014固定连接,且通过合理设置,使两个第三连杆3024同步且同向运动来带动转轴连接件2014运动,以提高转轴连接件2014的运动可靠性,从而提高整个键盘组件2的运动稳定性。
另外,可参照图13b,图13b为图13a中所示的键盘主体的另一角度下的结构示意图。其中,键盘主体201还可以包括边框组件2015,该边框组件2015包括第一边框20151、第二边框20152和横杆20153。其中,在沿转轴机构3的转动组件301的主轴3018的轴向方向上,第一边框20151和第二边框20152相对设置,且第一边框20151和第二边框20152均与转轴连接件2014固定连接,其连接方式可以但不限于为通过螺钉等紧固件紧固联接。这样,在转轴连接件2014随第三连杆3024移动的同时,可带动第一边框20151和第二边框20152随转轴连接件2014同步移动。
参照图14,图14为将图12中的键盘主体201的键盘盖板2013去掉后的局部结构示意图。由图14可以看出,按键2012位于第一边框20151和第二边框20152之间。另外,在本申请中,按键2012可为并列设置的多排,每排按键2012包括多个按键2012,且每排按键2012沿第一边框20151到第二边框20152的方向布置。
参照图15,图15为图14所示的键盘主体201的另一角度下的结构示意图。在该实施例中,横杆20153为多个,对应每排按键2012分别设置有一个横杆20153,且横杆20153的长度方向与每排按键2012的排列方向相同。另外,横杆20153可设置于相对应设置的按键2012的朝向如图13a所示的转轴机构3的一侧,也可以设置于对应的按键2012的背离转轴机构3的一侧,在本申请中不作具体限定。
在本申请中,第一边框20151和第二边框20152可带动横杆20153在其长度方向上移动。具体实施时,可参照图16,图16为图15中所示的键盘主体201的局部结构放大图。在本申请中,第一边框20151包括第一内边框201511和第一外边框201512,第一内边框201511和第一外边框201512并排设置,且第一内边框201511位于第一外边框201512的朝向按键2012的一侧。另外,第一外边框201512用于与如图13a所示的转轴连接杆2014 固定连接,第一内边框201511与多个横杆20153固定连接,其连接方式可以但不限于为通过螺钉等紧固件紧固联接。而第一外边框201512和第一内边框201511之间可通过第一连接杆组件2016连接。
参照图17,图17为图16中C处的局部结构放大图。在本申请中,该第一连接杆组件2016包括第一连接杆20161和第二连接杆20162。第一连接杆20161的第一端201611与第一内边框201511相铰接,第一连接杆20161的第二端201612与第一外边框201512相铰接。其中,第一连接杆20161与第一内边框201511和第一外边框201512均可以但不限于通过销轴铰接连接。第二连接杆20162的第一端201621与第一连接杆20161的杆体相铰接,第一连接杆20161的杆体为其位于第一端201611和第二端201612之间的部分。第二连接杆20162第二端201622可与键盘主体201的其它结构件相铰接,值得一提的是,该键盘主体201的其它结构件可为键盘主体201上的位置固定的任何结构件。在本申请中,位置固定的结构件是指无论键盘组件处于何种工作状态时,位置始终不发生变化的结构件,示例性的,图12中所示的键盘盖板2013即为键盘主体201上的位置固定的结构。相类似的,第二连接杆20162与第一连接杆20161和键盘主体201的结构件可以但不限于通过销轴铰接连接。另外,在本申请一个可能的实施例中,第二连接杆20162的第二端201622可位于第一端201621的背离第一内边框201511的一侧。
可继续参照图16,在本申请中,第二边框20152可以包括第二内边框201521和第二外边框201522,第二内边框201521和第二外边框201522并排设置,且第二内边框201521位于第二外边框201522的朝向按键2012的一侧。另外,第二外边框201522用于与如图13a中所示的转轴连接杆2014固定连接,第二内边框201521与多个横杆20153固定连接,其连接方式可以但不限于为通过螺钉等紧固件紧固联接。而第二外边框201522和第二内边框201521之间可通过第二连接杆组件2017连接,该第二连接杆组件2017包括第三连接杆和第四连接杆。与第一边框20151侧相类似的,在本申请中,第三连接杆的第一端与第二内边框201521相铰接,第三连接杆的第二端与第二外边框201522相铰接。其中,第三连接杆与第二内边框201521和第二外边框201522均可以但不限于通过销轴铰接连接。第四连接杆的第一端与第三连接杆的杆体相铰接,第二端可与键盘主体201的其它结构件相铰接,示例性的,可与键盘盖板2013相铰接。相类似的,第四连接杆与第三连接杆和键盘主体201的结构件可以但不限于通过销轴铰接连接。另外,在本申请一个可能的实施例中,第四连杆的第二端可位于第一端的背离第二内边框201521的一侧。
可继续参照图17,图17中用XY轴坐标系表示了第一边框20151和横杆20153的运动方向。其中,Y轴的正向指向转轴机构(图17中未示出,可参照图13a),X轴的正向指向第二边框(图17中未示出,可参照图16),另外,在本申请中,X轴的正向指向可与每排按键2012的排列方向相同或相反。以图17所示的键盘组件2处于展开状态为例对于第一边框20151带动横杆20153移动的过程进行说明。
在键盘组件2由图17所示的展开状态向闭合状态转动时,转轴机构3带动第一外边框201512向Y轴的正向移动,则第一连接杆20161的第二端201612随之向Y轴的正向移动。由于第二连接杆20162的第二端201622位于第一连接杆20161的Y轴的正向,则第一连接杆20161的第二端201612在沿Y轴的正向的移动,即为第一连接杆20161的第二端201612沿朝向第二连接杆20162的第二端201622的运动。另外,第二连接杆20162的第二端201622与键盘主体201的结构固定连接,则第二连接杆20162的第二端201622始 终处于一个固定的位置,且第二连接杆20162只能绕第二端201622转动。
参照图18,图18为键盘组件2处于闭合状态时第一连接杆20161和第二连接杆20162的相对位置关系。通过对比图17和图18可以看出,在键盘组件2由图17所示的展开状态向图18所示的闭合状态转动的过程中,第一连接杆20161和第二连接杆20162在X轴方向上的夹角减小,则第一连接杆20161的第一端201611和第二连接杆20162的第一端201621均沿X轴的正向移动,从而推动第一内边框201511沿X轴的正向移动,各个横杆20153在第一内边框201511的带动下沿朝向第二边框20152的方向移动。
可以理解的是,在上述过程中,第三连接杆和第四连接杆在X轴方向上的夹角增大,第三连接杆的第一端和第四连接杆的第一端均沿X轴的正向移动,以带动第二内边框201521沿X轴的正向移动,各个横杆20153在第二内边框201521的带动下沿背离第一边框20151的方向移动。
另外,当键盘组件2由图18所示的闭合状态向图17所示的展开状态转动时,各个横杆20153即在第一内边框201511和第二内边框201521的带动下沿X轴的负向移动。
由于在本申请中,在键盘组件2转动的过程中,第一外边框201512和第二外边框201522可沿朝向或者背离转轴机构的方向运动,从而带动第一内边框201511和第二内边框201521沿每排按键2012的排列方向同向运动,以使横杆20153可随之沿每排按键2012的排列方向往返移动。又每个横杆20153对应一排按键2012设置,基于此,为了实现按键2012在键盘组件2的不同折叠状态下的升降,可通过在横杆20153和对应的按键2012之间设置挤压机构,以通过横杆20153的往返移动挤压并推动按键2012进行升降。
具体实施时,可参照图19,图19展示了本申请一个可能的实施例的横杆20153的局部结构放大图。横杆20153可设置有第一抵接结构201531,该第一抵接结构201531可为多个,其具体可根据与该横杆20153对应设置的按键2012的数量进行设置。在本申请该实施例中,第一抵接结构201531可设置有第一倾斜面2015311。另外,多个第一抵接结构201531的第一倾斜面2015311的倾斜角度可以相同,也可以不同。
另外,可参照图20,图20展示了将横杆20153安装于键盘主体201的结构示意图。其中,键盘主体201具有多个按键槽位2018,且对应每个按键槽位2018,可容置有至少一个第一抵接结构201531,例如图20所示,每个按键槽位2018内可容置有两个第一抵接结构201531。
在本申请中,按键2012可包括键帽20121和升降机构,键帽20121覆盖且固定于升降机构,以起到对升降机构的保护作用。另外,键帽20121可作为按键2012的受力部件,则通过对键帽20121施加作用力将升降机构按下可实现键盘组件2的输入功能。而升降机构可在施加于键帽20121的作用力撤销后,带动键帽20121升起。参照图21,图21展示了本申请一个可能的实施例提供的升降机构20122的结构示意图。该升降机构20122可容置于如图20所示的按键槽位2018内,且升降机构20122设置有第二抵接结构201221,该第二抵接结构201221可设置有第二倾斜面2012211。另外,每个升降机构20122可以有多个第二抵接结构201221,例如图21所示,每个升降机构20122可设置有两个第二抵接结构201221。当每个升降机构20122有多个第二抵接结构201221时,该多个第二抵接结构201221的第二倾斜面2012211的倾斜方向可以相同,也可以不同。
参照图22,图22展示的是键盘组件2处于展开状态时横杆20153和按键2012的配合关系。在图22所示的实施例中,为便于表达横杆20153和按键2012的配合省略了键帽。 另外,与图17相比,图22中的键盘组件2的视图角度进行了调整,但是,在图22和图17中,Y轴和X轴的指向相同。
如图22所示,在本申请中,针对相对应设置的横杆20153和按键2012,位于同一按键槽位2018内的如图19所示的横杆20153的第一抵接结构201531的第一倾斜面2015311与如图21所示的升降机构20122的第二抵接结构201221的第二倾斜面2012211可相对设置,且第二倾斜面2012211相对于第一倾斜面2015311位于X轴的正向。另外,在图22所示的状态下,第一倾斜面2015311和相对设置的第二倾斜面2012211可间隔设置;或者第一倾斜面2015311和第二倾斜面2012211相接触,但二者之间没有挤压力,或者挤压力较小。此时,升降机构20122处于升起的状态,则整个按键2012可凸出于如图12所示的键盘盖板2013的表面,以便于通过敲击按键2012来实现键盘组件2的输入功能。
由上述实施例的介绍可以知道,当键盘组件2由图22所示的展开状态向闭合状态转动时,横杆20153可沿X轴的正向移动,而第二抵接结构201221的第二倾斜面2012211相对于第一抵接结构201531的第一倾斜面2015311位于X轴的正向。则在横杆20153沿X轴正向移动时,可使第一倾斜面2015311对第二倾斜面2012211施加挤压力。可参照图23,图23展示了键盘组件2处于闭合状态时横杆20153和按键2012的配合关系。由图23可以看出,在键盘组件2处于闭合状态时,升降结构20122在第一倾斜面2015311对第二倾斜面2012211施加的挤压力的作用下带动按键帽降落,以使按键2012可以隐藏于对应的按键槽位2018内。从而使键盘组件2在闭合状态下的厚度较小,以顺应电子设备的薄型化设计的要求,提升用户的使用体验。
另外,当键盘组件2由闭合状态向展开状态转动时,横杆20153沿X轴负向移动,则第一倾斜面2015311对第二倾斜面2012211施加的挤压力越来越小,升降机构20122可带动键帽20121由对应的按键槽位2018内升起,并使键帽20121能够凸出于如图12所示的键盘盖板2013的表面,以用于实现按键2012的功能。
值得一提的是,本申请提供的按键2012随键盘组件2的折叠状态进行升降的方案,除了可以应用于本申请的键盘组件2中外,也可以应用于其它具有键盘的可折叠电子设备,示例性的,可应用于笔记本电脑,其具体设置方式可参照本申请上述实施例,在此不进行赘述。
由前述实施例的介绍可以知道,可参照图2,键盘组件2的支撑部202可用于对安装于第一支撑板2021的主机1起到支撑的作用。则在键盘组件2由闭合状态到展开状态,以及由展开状态到闭合状态的过程中,对于支撑部202的运动的稳定性具有较高的要求。
基于此,参照图24,图24为本申请另一个可能的实施例提供的转轴机构3的结构示意图。在该实施例中,转轴机构3还可以包括凸轮303。该凸轮303可随转动组件301的主轴3018同步转动,即在沿主轴3018的径向方向上,凸轮303与主轴3018相对固定。其中,可以在凸轮303上设置异形孔,示例性的可以但不限于为D形孔。同时使主轴3018的穿设于凸轮303的部分的截面也设置为可与异形孔相匹配的异形截面,以实现凸轮303和主轴3018在径向方向上的限位。
可继续参照图24,在凸轮303的表面上设置有凸轮滑槽3031。另外,可参照图25a,图25a为本申请一个实施例提供的键盘组件2处于闭合状态时的局部结构示意图。在图25a中展示了支撑部202的第四支撑板2024在该闭合状态下的结构。该第四支撑板2024设置有辅助支撑机构20241,该辅助支撑机构20241包括第一支撑杆202411和第二支撑杆 202412,该第一支撑杆202411和第二支撑杆202412交叉设置,且第一支撑杆202411和第二支撑杆202412的中间部位相铰接。
另外,第四支撑板2024设置有滑轨20242和滑轨20243,滑轨20242和滑轨20243可沿背离键盘主体201的方向延伸。在滑轨20242内设置有第一滑块20244,滑轨20243内设置有第二滑块20245。可继续参照图25a,在本申请中,第一滑块20244和第二滑块20245均可与第四支撑板2024固定连接。
由上述实施例的介绍可以知道,为了使转轴机构3的运动较为稳定,可在转轴机构3的长度方向的两个端部各设置一个转动组件301。另外,在本申请中,可对应每一个转动组件301设置一个凸轮303。
这样,可使辅助支撑结构位于两个转动组件301之间,且第一支撑杆202411的一端可容置于一个凸轮303的凸轮滑槽3031内,另一端与第一滑块20244相铰接。第二支撑杆202412的一端容置于另一个凸轮303的凸轮滑槽3031内,另一端与第二滑块20245相铰接。参照图25b,图25b展示了图25a所示的支撑部202的第四支撑板2024在键盘组件2处于展开状态下的结构。一并参照图25a和图25b,在由图25a所示的闭合状态到图25b所示的展开状态的过程中,凸轮303可随转动组件301的主轴3018转动,以推动第一支撑杆202411的容置于对应的凸轮滑槽3031的一端,与第二支撑杆202412的容置于对应的凸轮滑槽3031的一端沿主轴3018的轴向相靠近运动。由于第一支撑杆202411与第二支撑杆202412相铰接,则在上述过程中,第一支撑杆202411可推动第一滑块20244沿滑轨20243向背离键盘主体201的方向滑动,第二支撑杆202412可推动第二滑块20245沿滑轨20242向背离键盘主体201的方向滑动。又由于第一滑块20244和第二滑块20245均与第四支撑板2024固定连接,则在第一滑块20244和第二滑块20245向背离键盘主体201的方向滑动的过程中,可推动第四支撑板2024向背离键盘主体201的方向滑动。这样,可在键盘组件2在展开的过程中,提高支撑部202的运动稳定性,从而可使键盘组件2对设置于第一支撑板2021的主机1起到稳定的支撑,以提高用户体验。
可以理解的是,在本申请中,凸轮滑槽3031的轨迹形状可根据第一支撑杆202411和第二支撑杆202412,以及第一滑块20244和第二滑块20245的运动方向进行设计,以在第一支撑杆202411和第二支撑杆202412绕其铰接点转动的过程中能够推动第一滑块20244和第二滑块20245稳定的滑动即可。
本申请提供的转轴机构3,除了可以包括上述结构外,还可以设置有自动开合装置304,自动开合装置304可以包括电机3041。在将该转轴机构3应用于键盘组件2时,可以通过电机3041驱动转轴机构3运动,来实现键盘组件2的展开及闭合,以简化用户的操作步骤。
另外,由于用户对于可折叠的设备的使用角度存在个性化的要求。则在通过电机3041驱动键盘组件2进行展开以及闭合的过程中,可能会根据自己的需要下意识的干预该过程。而若电机3041提供的扭矩不足,会造成电机3041或者其它机构件的损坏。为了解决这一问题,以使电机3041能够安全可靠的运行,本申请提供的自动开合装置304中还可以设置有保护机构3042。
具体实施时,可参照图26,图26展示了本申请一种实施例提供的转轴机构3的结构示意图。在本申请该实施例中,转轴机构3除了包括上述的转动组件301外,还包括自动开合装置304。该自动开合装置304包括电机3041和保护机构3042,该保护机构3042可 以但不限于为离合器。其中,保护机构3042位于电机3041和转动组件301之间,电机3041可用于驱动转轴机构3转动,以实现键盘组件的自动开合功能。保护机构3042可对电机3041起到保护的作用。在正常工作状态下,电机3041通过保护机构3042将扭矩传递给转动组件301,以驱动转动组件301转动。当出现对电机3041施加的负载过大的情形时,保护机构3042可对施加于电机3041的负载进行调节,从而避免电机的损坏。
参照图27,图27为本申请一实施例提供的保护机构3042的结构示意图。该保护机构3042包括固定架30421,该固定架30421可作为整个保护机构3042的支撑座,以对于保护机构3042的其它结构起到支撑的作用。另外,固定架30421可以设置有第一固定板304211和第二固定板304212,第一固定板304211和第二固定板304212相对设置,以在第一固定板304211和第二固定板304212之间形成一个安装空间。

参照图29a,滑动销304234位于固定销304233和第一止位部3042322之间,滑动销304234套设于如图28所示的第二轴304231,且可沿第二轴304231的轴向滑动。在本申请中,滑动销304234的朝向固定销304233的一端设置有销轴3042341,该销轴3042341可插设于固定销304233的开槽3042331内,且可沿开槽3042331滑动。
可以理解的是,在本申请中,固定销304233上的开槽3042331可以为一个,也可以为多个。滑动销304234上设置的销轴3042341可对应开槽3042331设置,以有利于提高滑动销304234沿固定销304233的开槽3042331滑动的稳定性。
另外,继续参照图29a,在滑动销304234的背离固定销304233的一端还设置有第二止位部3042342,该第二止位部3042342可为一凸起结构,在滑动销304234沿背离第一固定板304211的方向滑动时,第二止位部3042342可插接于第一止位部3042322的缺口30423221,从而使滑动销304234与第二齿轮件304232相对锁止。由于滑动销304234的销轴3042341始终位于固定销304233的开槽3042331内,而固定销304233与转动组件的主轴固定连接,则在第二止位部3042342插接于第一止位部3042322的缺口30423221时,第二齿轮件304232可随固定销304233同步转动。
可继续参照图29a,滑动销304234的朝向第一齿轮件304222的一侧还可以设置有第一卡接部(图29a中未示出),同时在第一齿轮件304222上还可以设置有第二卡接部(图28中未示出),第一卡接部可与第二卡接部相卡接,以在第一齿轮件304222沿第一轴304221滑动时,可推动滑动销304234沿第二轴304231向与第一齿轮件304222相反的方向滑动。在本申请中,不对第一卡接部和第二卡接部的具体结构进行限定,示例性的,第一卡接部可为凸起,其形状可以但不限于为梯形。另外,第二卡接部可为凹槽,凸起卡入 凹槽,以实现第一卡接部和第二卡接部的卡接。在本申请另外一些实施例中,第一卡接部也可以为凹槽,而第二卡接部可以为凸起。
可继续参照图29a,第二轴304231的朝向第二固定板304212的一端还可以设置有电机连接件304235。该电机连接件304235可用于与电机的转轴固定连接。另外,第二转轴组件30423还可以包括转接件30425,该转接件30425位于第二转轴组件30423和第二固定板304212之间,且转接件30425与第二转轴组件30423相抵接。在本申请中,转接件30425可套设于第二轴,转接件30425可与电机连接件304235相连接,且转接件30425可随电机连接件304235转动。
如图29a所示,转接件30425的表面可设置有第四齿轮结构304251,第一齿轮件304222的第二齿轮结构3042222与该第四齿轮结构304251相啮合。在本申请中,图29a中展示了键盘组件处于闭合状态时,保护机构3042的结构示意图。参照图29b,图29b为图29a的E向视图。图29b展示了在该闭合状态下,转接件30424侧的结构。在该闭合状态下,第一齿轮结构3042221和第三齿轮结构3042321相啮合,第二齿轮结构3042222和第四齿轮结构304251相啮合。另外,固定销304233上的导向结构3042332插设于导向槽结构3042223的导向槽30422231内。
在键盘组件由闭合状态到展开状态的过程中,如图26所示的电机3041运转并通过电机连接件304235带动转接件30425转动。由于第一齿轮件304222的第二齿轮结构3042222和转接件30425的第四齿轮结构304251相啮合,则转接件30425转动可带动第一齿轮件304222转动。另外,又由于第一齿轮件304222的第一齿轮结构3042221与第二齿轮件304232的第三齿轮结构相啮合,则在第一齿轮件304222转动可带动第二齿轮件304232转动。
可参照图29a,在闭合状态下,滑动销304234的第二止位部3042342插设于第二齿轮件304232的第一止位部3042322的缺口30423221内,滑动销304234的销轴3042341插设于固定销304233的开槽3042331内。这样,在键盘组件由闭合状态到展开状态的过程中,第一齿轮件304222转动可带动第二齿轮件304232转动,而第二齿轮件304232转动可带动滑动销304234和固定销304233随之转动。而固定销304233又通过转接件30424与转动组件的主轴相连接,从而可带动转动组件的主轴随固定销304233转动。
另外,在第一齿轮件304222转动的过程中,固定销304233的导向结构3042332可沿导向槽结构3042223的导向槽30422231滑动,导向槽结构3042223的导向槽30422231与固定销304233的导向结构3042332相互作用。则通过合理设计,可以使固定销304233的导向结构3042332在沿导向槽结构3042223的导向槽30422231滑动的过程中,推动第一齿轮件304222沿第一轴304221向第二固定板304212的方向滑动。又由上述实施例的介绍可以知道,滑动销304234可随第一齿轮件304222同步滑动,则在第一齿轮件304222沿第一轴304221向第二固定板304212的方向滑动的过程中,可推动滑动销304234沿第二轴304231向第一固定板304211的方向滑动。
参照图30a,图30a展示了键盘组件处于展开状态时,保护机构3042的结构示意图。参照图30b,图30b为图30a的F向视图。图30b展示了在该闭合状态下,转接件30424侧的结构。当键盘组件处于展开状态时,第一齿轮结构3042221和第三齿轮结构3042321相错位,以断开第一齿轮件304222和第二齿轮件304232的啮合关系。但此时,第二齿轮结构3042222和第四齿轮结构304251仍处于啮合的状态。另外,此时,滑动销304234的 第二止位部3042342脱离第二齿轮件304232的如图28所示的第一止位部3042322的缺口30423221,则滑动销304234与第二齿轮件304232之间没有连接关系。
可以理解的是,键盘组件的闭合通常可通过用户操作来实现。具体实施时,用户可对键盘组件的支撑部的第一支撑板施加朝向键盘主体方向的作用力。由前述实施例的介绍可以知道,在键盘组件由展开状态到闭合状态的过程中,第一支撑板朝向键盘主体运动可带动转动组件的主轴转动。可一并参照图29a和图30a,键盘组件由展开状态到闭合状态的过程中,则为保护机构由图30a所示的状态向图29a所示的状态的运动过程。由于转动组件的主轴与转接件30424可同步转动,在该过程中,第一齿轮件304222在固定销304233的导向结构3042332与导向槽30422231的配合下沿第一轴304221向第一固定板304211的方向滑动,从而使第一齿轮件304222和第二齿轮件304232的对应的齿轮结构重新啮合。另外,在第一齿轮件304222在向第一固定板304211的方向滑动的过程中,可带动滑动销304234向第二固定板304212的方向滑动,从而使滑动销304234的第二止位部3042342重新插设于第二齿轮件304232的第一止位部3042322的缺口30423221内。
在对本申请提供的保护机构3042的结构以及其工作原理进行了了解之后,接下来对保护机构3042对于如图26所示的电机3041的保护的实现方式进行介绍。
参照图31,图31为本申请一实施例提供的保护机构3042的剖面图。为便于说明,在图31中只展示了第二转轴组件30423处的剖面结构,而省略了第一转轴组件30422处的剖面结构。
可参照图31,转接件30425开设有容置腔304252,该容置腔304252的开口朝向电机连接件304235。电机连接件304235包括转动中心件3042351,该转动中心件3042351可插设于该容置腔304252。可继续参照图31,在本申请中,第二轴304231可插设于转动中心件3042351。另外,该转动中心件3042351的背离转接件30425的一端可贯穿第二固定板304212,以用于与电机进行连接。
另外,电机连接件304235还可以包括壳体3042352,该壳体3042352套设于转动中心件3042351,且壳体3042352可固定于第二固定板304212。由图31可以看出,在本申请一个可能的实施例中,在壳体3042352与转动中心件3042351之间可以设置有滚珠,该滚珠可为多个,壳体3042352与转动中心件3042351均与滚珠相抵接,从而可使壳体3042352与转动中心件3042351之间的摩擦力为滚动摩擦力,以降低二者损坏的风险,延长其使用寿命。
继续参照图31,转接件30425还设置有弹性件304253,该弹性件304253容置于容置腔304252,且弹性件304253套设于电机连接件304235的转动中心件3042351。在本申请中,不对弹性件304253的具体设置形式进行限定,其示例性的可包括多个相叠置的弹簧片。另外,弹性件304253发生形变可在转接件30425与转动中心件3042351之间形成弹性作用力。
转接件30425还可以设置有滚动件304254,该滚动件304254容置于容置腔304252内。另外,转接件30425的容置腔304252的底壁还设置有凹槽,滚动件304254可容置于该凹槽内,且弹性件304253的一端将滚动件304254压向容置腔304252的底壁,另一端与转动中心件3042351相抵接。在本申请中,不对滚动件304254的具体设置形式进行限定,其示例性的可为滚珠或者滚柱。另外,滚动件304254可为一个或者多个,且滚动件304254可一一对应的容置于对应的凹槽内。
可继续参照图31,在弹性件304253与滚动件304254之间还可以设置有压块304255,弹性件304253通过该压块304255将滚动件304254压向对应的凹槽。其中,压块304255的用于与滚动件304254接触的表面设置有弧形槽,滚动件304254的至少部分可容置于该弧形槽,以避免滚动件304254在运动的过程中脱落。
在本申请中,滑动销304234与第二齿轮件304232之间还设置有垫片304236,该垫片304236的材质可以但不限于聚甲醛(polyformaldehyde,POM)。滑动销304234和第二齿轮件304232均与垫片304236相抵接,以在第二齿轮件304232与滑动销304234相对转动的过程中产生扭矩,并可减小二者的磨损,以提高其结构的可靠性。
可以理解的是,在键盘组件处于展开状态下,若手动将其闭合时,由于滑动销304234可随固定销304233转动。这时,在滑动销304234与第二齿轮件304232之间可产生转动摩擦力,该摩擦力可以在键盘组件处于不同状态下产生不同的扭矩,提供给消费者不同的手感体验。
另外,采用本申请提供的转轴机构,在通过电机驱动键盘组件进行开合的过程中,如果人为干涉该过程,使转接件30425带给电机连接件304235的扭矩超过设定值(即电机的负荷过载)时,转接件30425在转动的过程中产生的扭矩可克服弹性件304253施加于滚动件304254的弹性挤压力,从而使滚动件304254脱离对应的凹槽。此时,可切断转接件30425与电机连接件304235的连接关系,则作用于转接件30425的扭矩不会作用于电机连接件304235,从而不会对连接于电机连接件304235的电机造成损坏。
因此,在本申请中,转接件30425可作为保护机构3042与电机3041之间的扭矩限制器,以避免过大的外界扭矩反作用到电机,从而起到限制扭矩过载保护电机3041的作用。
采用本申请提供的自动开合装置,可以在手动和电动工作模式的切换时,通过转接件30425和电机连接件304235之间的连接关系的切换来产生不同的扭矩,从而可满足手动和电动两种工作模式下所需的扭矩,以满足用户体验。另外,转接件30425和电机连接件304235之间的扭矩,以及第二齿轮件304232与转接件30425之间的扭矩均可通过弹性件304253来实现,其有利于减小自动开合装置所占用的空间,以实现其小型化设计。
在本申请中,通过自动开合装置驱动键盘组件开合的过程中,为了提高键盘组件运动的稳定性,可以在转轴机构中设置多组自动开合装置。示例性的,可以在转轴机构的长度方向的两个端部分别设置一个自动开合装置,这样,通过采用两个自动开合装置同步驱动的方式,可有效的提高键盘组件运动的稳定性。
在本申请中,转轴机构3的转动组件301除了可采用上述实施例提供的设置方式外,还可以采用其它可能的设置方式。示例性的,可参照图32a,图32a为本申请另一种实施例提供的转动组件301的结构示意图。在图32a中展示了键盘组件2处于闭合状态时,转动组件301的结构示意图。另外,参照图32b,图32b展示了键盘组件2处于展开状态时,转动组件301的结构示意图。
可一并参照图32a和图32b,该转动组件301包括连接件3011、第一固定件3012和第二固定件3013。其中,第一固定件3012和第二固定件3013可与上述的键盘主体固定连接,其连接方式可以但不限于为通过螺钉等紧固件连接。另外,第一固定件3012和第二固定件3013可作为整个转动组件301的支撑件,第一固定件3012和第二固定件3013间隔设置,转动组件301的其它结构均可以通过直接或者间接的方式与第一固定件3012和第二固定件3013连接。
为了便于对转动组件301的各结构之间的连接关系进行理解,可以参照图33,图33为图32a中所示的转动组件301的爆炸图。在该实施例中,连接件3011包括呈长条结构设置的本体部30111,该本体部30111可与上述的主机支撑件固定连接,其连接方式可以但不限于为通过螺钉等紧固件锁紧。继续参照图33,本体部30111可为两段,连接件3011还包括设置于两段本体部30111之间的连接结构,该连接结构用于将两端本体部30111连接。
在本申请中,转动组件301还包括第一连杆3016和第二连杆3017,第一连杆3016位于连接件3011与第二连杆3017之间。第一连杆3016的朝向连接件3011的一端与连接件3011的连接结构通过第一转轴3015a转动连接,第一连杆3016的朝向第二连杆3017的一端与第二连杆3017通过第二转轴3015b转动连接。
可继续参照图33,本申请该实施例提供的转动组件301还可以包括主轴3018,该主轴3018穿设于第一固定件3012、第二连杆3017和第二固定件3013。其中,主轴3018与第一固定件3012和第二固定件3013可相对转动。另外,在主轴3018的径向方向上,第二连杆3017与主轴3018相对固定,则第二连杆3017可与主轴3018绕主轴3018的轴线同步转动。在本申请一个可能的实施例中,为了将第二连杆3017与主轴3018在径向方向上相对固定,可以在第二连杆3017上设置异形孔,示例性的可以但不限于为D形孔。同时使主轴3018的穿设于第二连杆3017的部分的截面也设置为可与异形孔相匹配的异形截面,以实现第二连杆3017和主轴3018在径向方向上的限位。
在本申请中,为了能够使转动组件301能够在整个转轴机构运动的过程中为其提供对应转动位下的阻尼力,以使转轴机构能够保持在对应的转动位,可以继续参照图33,在本申请一个可能的实施例中,还可使转动组件301设置有弹性件3019,该弹性件3019在受压时可积蓄弹性作用力。如图33所示,该弹性件3019可以设置于第一固定件3012的背离第二固定件3013的一侧,在本申请中不对弹性件3019的具体设置形式进行限定,其示例性的可包括弹性碟片,该弹性碟片可为一个或者多个。当弹性件3019包括多个弹性碟片时,该多个弹性碟片可相叠置设置。另外,可参照图33,弹性件3019可套设于主轴3018,在该实施例中,当弹性件3019受压时,其会产生沿主轴3018的轴向方向的弹性作用力。
另外,为了避免弹性件3019从主轴3018上脱落,还可以在弹性件3019的背离第一固定件3012的一侧设置限位件3020,该限位件3020示例性的可为螺母,以便于组装及拆卸。该限位件3020套设于主轴3018,且对弹性件3019的沿主轴3018的轴向方向进行限位。在本申请中,为了能够对弹性件3019施加有效的作用力,还可以设置有一组垫片3021,该一组垫片3021套设于主轴3018,弹性件3019设置于该一组垫片3021之间。另外,还可以使垫片3021的外圈直径大于或等于弹性件3019的外圈直径。限位件3020可与位于弹性件3019的背离第一固定件3012的一侧的垫片3021相抵接。
值得一提的是,在本申请中,弹性件3019沿主轴3018的轴向可发生形变,且弹性件3019发生形变产生的弹性作用力可作用于第一固定件3012,以在第一固定件3012与弹性件3019之间产生摩擦力,该摩擦力可阻碍主轴3018的转动。又由于第二连杆3017可与主轴3018同步转动,而第二连杆3017可带动连接件3011转动,连接件3011又与固定于如图3b所示的第一支撑板2021的主机支撑件4固定连接。因此,当第二连杆3017随主轴3018的转动被阻碍时,第一支撑板2021的运动会受到阻碍,这样即将弹性件3019产生的弹性作用力转化为阻碍转轴机构转动的阻尼力。
可以理解的是,主机1可固定于第一支撑板2021,当主机1随第一支撑板2021转动的过程中到达某一转动位时,若主机1的重力产生的扭矩与上述转轴机构3的阻尼力产生的扭矩相等,则在没有外力的作用下,第一支撑板2021即可悬停在该对应的转动位。
由于转轴机构3在任何转动位下所需要的阻尼力不同,而该阻尼力的改变可通过弹性件3019产生的弹性作用力的改变来实现,弹性件3019的弹性作用力的改变可通过其形变的改变来实现。在本申请一个可能的实施例中,为了能够使弹性件3019在不同的转动位下具有对应的形变,可在第一固定件3012与弹性件3019之间设置挤压接触面。具体实施时,可继续参照图33,在弹性件3019和第一固定件3012之间设置有第一挤压结构3022,该第一挤压结构3022套设于主轴3018,且弹性件3019可将第一挤压结构3022压向第一固定件3012,以使第一挤压结构3022在弹性件3019的弹性作用力下与第一固定件3012相抵接。另外,在沿主轴3018的径向方向上,第一挤压结构3022与主轴3018相对固定。其中,可以在第一挤压结构3022上设置异形孔,示例性的可以但不限于为D形孔。同时使主轴3018的穿设于第一挤压结构3022的部分也设置为可与异形孔相匹配的异形截面,以实现第一挤压结构3022和主轴3018在径向方向上的限位。
在本申请该实施例中,第一挤压结构3022可参照图9所示的第一挤压结构3022进行设置,在此不进行详细的描述。由上述实施例的介绍可以知道,第一挤压结构3022的朝向第一固定件3012的端面可设置有第一凹槽30221。
另外,在该转动组件301中还可以设置有第二挤压结构3026,参照图34,图34为本申请一个可能的实施例提供的第二挤压结构3026的结构示意图。可一并参照图33和图34,该第二挤压结构3026设置于第一挤压结构3022与第一固定件3012之间,主轴3018可与第二挤压结构3026转动连接。弹性件3019可将第一挤压结构3022压向第二挤压结构3026,另外,在第二挤压结构3026的朝向第一挤压结构3022的端面可以设置有第一凸起30261,该第一凸起30261可与上述的第一挤压结构3022的第一凹槽30221对应设置。可以理解的是,在本申请另外一些实施例中,第一凹槽30221也可以设置于第二挤压结构3026的朝向第一挤压结构3022的端面,同时第一凸起30261可设置于第一挤压结构3022的朝向第二挤压结构3026的端面。
当相对应设置的第一凸起30261落入第一凹槽30221内,以使第一凹槽30221与第一凸起30261相配合卡接时,第一挤压结构3022与第二挤压结构3026在沿主轴3018的轴向方向上的总长度最小,此时,弹性件3019受到的挤压力最小,从而产生的弹性作用力最小,则第一挤压结构3022与第二挤压结构3026之间的摩擦力最小。当第一挤压结构3022与第二挤压结构3026相对转动后,第一凹槽30221与第一凸起30261相错时,第一挤压结构3022与第二挤压结构3026在沿主轴3018的轴向方向上的总长度增大,从而使弹性件3019积蓄弹性作用力,在该弹性作用力下,第一挤压结构3022与第二挤压结构3026之间的摩擦力增大,从而使转轴机构的阻尼力增大。
值得一提的是,在本申请中,可通过对第一凹槽30221和第一凸起30261进行合理的设计,以使转轴机构3的阻尼力在对应键盘组件处于闭合状态时最大,以使键盘组件能够稳定的维持在该闭合状态。
可继续参照图33,在本申请中,转动组件301中还可以设置有弹性件3023,该弹性件3023示例性的可为扭簧。一并参照图32a和图33,该弹性件3023设置于第二固定件3013的背离第一固定件3012的一侧,且该弹性件3023套设于主轴3018,弹性件3023可相对 主轴3018转动。另外,转动组件301还包括旋转固定件3027,该旋转固定件3027位于弹性件3023的背离第二固定件3013的一侧,旋转固定件3027套设于主轴3018,且在沿主轴3018的径向方向上,旋转固定件3027与主轴3018固定连接。旋转固定件3027设置有卡槽30271,弹性件3023的一端可卡设于该卡槽30271,另一端可固定于第二固定件3013。这样,在主轴3018转动的过程中,可使弹性件3023产生弹性变形,从而产生绕主轴3018轴线方向的弹性作用力。基于此,通过合理设计,可使弹性件3023产生的弹性作用力为主轴3018的转动提供辅助力,从而可在对连接件3011施加较小的作用力时,即可带动主轴3018转动,其可提高用户对应用有该转动组件301的键盘组件进行开合操作的舒适性。
另外,转动组件301还可以设置有套筒3028,该套筒3028可套设于主轴3018,弹性件3023可套设于该套筒3028。该套筒3028可为弹性件3023的沿轴向的运动提供导向作用,以提高弹性件3023运动的稳定性。
可继续参照图33,转动组件301还可以包括第三连杆3024,该第三连杆3024可沿第二固定件3013滑动。另外,可参照图35,图35为图32a所示的转动组件301的另一个角度下的结构示意图。在该实施例中,第二固定件3013的背离连接件3011的一侧设置有滑轨30133,第三连杆3024可容置于该滑轨30133,且可沿滑轨30133滑动。
在本申请一些实施例中,为避免第三连杆3024从滑轨30133中脱落,可继续参照图35,滑轨30133的侧壁上可设置有第一限位部301331,第三连杆3024可设置有第二限位部30242,第二限位部30242可与第一限位部301331相卡接,且可在第一限位部301331内滑动。其中,第一限位部301331可为滑槽,第二限位部30242可为凸起,以使凸起可与滑槽相卡接。可以理解的是,在本申请另一些实施例中,第一限位部301331也可为凸起,而第二限位部30242可为凹槽。这样,第一限位部301331和第二限位部30242的配合,可为第三连杆3024沿滑轨30133的滑动提供导向的作用,从而可提高第三连杆3024运动的可靠性。
在转动组件301转动的过程中,为了实现第三连杆3024在滑轨30133内的滑动,由图33可以看出,第三连杆3024的朝向第二固定件3013的一侧具有连接部30241。由于转动组件301转动的可通过主轴3018的转动来实现,因此,在本申请中,可将第三连杆3024通过连接部30241与主轴3018相连接。具体实施时,可参照图33,本申请提供的转动组件301还可以设置有摆杆结构3029,该摆杆结构3029可以设置于第二固定件3013的背离第一固定件3012的一侧。摆杆结构3029可套设于主轴3018,另外,在沿主轴3018的径向方向上,摆杆结构3029与主轴3018固定连接,以使摆杆结构3029可随主轴3018同步转动,该摆杆结构3029具有突出部30291。
另外,可参照图36a,图36a为图35中所示的转动组件301的G-G处的剖面图。可一并参照图33和图36a,在第三连杆3024的连接部30241可设置有轨迹槽302411,摆杆结构3029的突出部30291可置插设于该轨迹槽302411,且可与该轨迹槽的302411槽壁相接触。这样,在主轴3018转动的过程中,可带动摆杆结构3029同步转动,从而使摆杆结构3029的突出部30291沿轨迹槽302411的槽壁滑动。
可以理解的是,通过对轨迹槽302411进行合理的设计,可以实现对第三连杆3024的运动轨迹的设计,示例性的,可以在转动组件301处于如图36a所示的闭合状态时,使摆杆结构3029的突出部30291与轨迹槽302411的背离连接件3011的槽壁相抵接,从而使第三连杆3024能够隐藏于第二固定件3013。另外,可参照图36b,图36b为转动组件301 处于由闭合状态到展开状态的中间状态时,第三连杆3024的突出部30291在轨迹槽302411内的相对位置。由图36b可以看出,对应于该中间状态,轨迹槽302411可设置有一个凹陷部3024111,突出部30291可伸入该凹陷部3024111。在转动组件301由图36b所示的中间状态下,继续将其展开的过程中,突出部30291可挤压凹陷部3024111的侧壁,以推动第三连杆3024向朝向连接件3011的方向滑动。参照图36c,图36c为转动组件301处于展开状态时,第三连杆3024的突出部30291在轨迹槽302411内的相对位置。在转动组件301处于图36c所示的展开状态时,第三连杆3024可由第二固定件3013向靠近连接件的方向伸出。例如,在将该转动组件301用于键盘组件时,键盘组件由闭合状态到展开状态的过程中,第三连杆3024可沿朝向键盘主体的方向滑动。相反的,当键盘组件由展开状态到闭合状态的过程中,第三连杆3024可在滑轨内沿背离连接件3011的方向滑动,从而使第三连杆3024沿背离键盘主体的方向滑动。
值得一提的是,本申请该实施例提供的转轴机构在用于键盘组件时,第三连杆3024可用于与上述如图13a所示的键盘主体201的转轴连接件2014进行连接。这样,在第三连杆3024随主轴3018转动而滑动的过程中,可带动转轴连接件2014沿朝向或者背离转轴机构3的方向移动。可以理解的是,在本申请中,可在第三连杆3024沿朝向键盘主体201的方向滑动时带动转轴连接件2014沿背离转轴机构3的方向移动,而在第三连杆3024沿背离键盘主体201的方向滑动时带动转轴连接件2014沿朝向转轴机构3的方向移动。又或者,可在第三连杆3024沿朝向键盘主体201的方向滑动时带动转轴连接件2014沿朝向转轴机构3的方向移动,而在第三连杆3024沿背离键盘主体201的方向滑动时带动转轴连接件2014沿背离转轴机构3的方向移动。从而在键盘组件处于展开状态时,键盘主体201上的按键处于升起的状态;而在键盘组件处于闭合状态时,键盘主体201上的按键降落。其中,键盘主体的具体设置方式可参照上述实施例,在此不进行赘述。
另外,当该转轴机构还设置有自动开合装置时,本申请该实施例的转动组件与自动开合装置之间的连接关系,自动开合装置驱动转动组件的运动方式,以及自动开合装置的具体设置方式等均可参照上述实施例,在此不进行赘述。
值得一提的,在本申请中,可以将包括上述任意实施例所提到的支撑部202和转轴机构3的结构定义为支撑组件。该支撑组件除了可以采用上述实施例中介绍的依赖于键盘组件2的具体结构来实现第一支撑板2021转动带动第三支撑板2023沿朝向或者背离转轴机构3的方向滑动外,也可以在不依赖于上述的键盘组件2的结构进行设置的情况下,使第一支撑板2021在绕转轴机构3转动时,能够带动第三支撑板2023沿朝向或者背离转轴机构3的方向滑动,从而可在第一支撑板2021、第二支撑板和第三支撑板2023之间形成稳定的支撑结构。
另外,该支撑组件可用于电子设备,该电子设备还可以包括主机1,该主机1示例性的可为前述实施例中的平板电脑等。该主机1可固定于第一支撑板2021,主机1可随第一支撑板2021沿设定的轨迹运动。另外,在第一支撑板2021运动并带动第三支撑板2023沿朝向或背离转轴机构3的方向滑动的过程中,第一支撑板2021、第二支撑板和第三支撑板2023之间能够形成围绕转轴机构3的三角支撑结构,其可有利于提高该支撑部202对于主机1的支撑稳定性,从而提高电子设备的结构可靠性。
在本申请一个可能的实施例中,可以将包括上述任意实施例所提到的保护机构3042和电机的结构定义为电机组件。该电机组件除了可以采用上述实施例中介绍的依赖于键盘 组件2的具体结构来实现其对于电机的保护外,也可以在不依赖于上述的键盘组件2的结构进行设置的情况下,当电机带动转动中心件转动,且作用于转接件30424的扭矩小于转接件30424与转动中心件之间的连接力时,转接件30424与电机连接件连接,转接件30424随转动中心件转动,且转接件30424带动第一齿轮件绕第一轴转动;第一齿轮件转动的扭矩传递给第二转轴组件。而当作用于第二转轴组件的扭矩通过第一齿轮件传递给转接件30424,且作用于转接件30424的扭矩大于转接件30424与转动中心件之间的连接力时,使转接件30424与电机连接件的连接断开。从而实现对于电机的保护。
在将该电机组件应用与电子设备时,该电子设备除了为二合一产品外,也可以为其它可能的可折叠电子设备。该电子设备只要包括可以相对一个任意形式的转轴机构3转动的两部分即可。示例性的,电子设备可以包括第一壳体和第二壳体,则电机组件可用于驱动两个壳体相对一个转轴机构3,从而实现该电子设备的电动开合,从而可简化用户开合电子设备的操作步骤,其有利于提升用户体验。另外,在人为干预电子设备的电动开合等场景下,该电机组件可对电机起到保护的作用,从而实现电子设备的安全可靠的自动开合功能,以延长其使用寿命。
另外,本申请上述任意实施例提到的键盘主体201的转轴连接件2014除了可与本申请上述实施提供的转轴机构连接外,还可以采用任意其他可能的转轴机构,只要能够在转动机构运动的过程中,可带动转轴连接件沿朝向或者背离转轴机构即可。
本申请提供的键盘主体201除了可用于上述的键盘组件2外,还可以用于笔记本电脑等电子设备中。这些电子设备除了包括键盘主体201还可以包括显示屏,显示屏与键盘主体201可通过转轴机构3转动连接。则在电子设备展开时,按键2012可朝向露出于按键槽的方向运动至设定行程,以满足用户通过按键2012敲击输入的使用要求。而在电子设备闭合时,可使按键2012朝向按键槽内运动,从而使按键2012露出于按键槽的部分较小,从而使整个键盘主体201的在厚度方向上的尺寸较小,以有利于实现键盘主体201的薄型化设计,从而可实现电子设备在该状态下的薄型化设计。
显然,本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样,倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
