Description

键盘组件、设备框架及电子设备 技术领域
本申请涉及终端技术领域，尤其涉及一种键盘组件、设备框架及电子设备。
背景技术
近年来，随着笔记本电脑的小型化及轻薄化，键盘的体积越来越小，厚度越来越薄，而键盘的厚度直接影响到键程的大小，这对保持和改善键击感觉提出了更高的挑战。因此，在终端产品小型化的趋势下如何保证足够长的键程，为消费者提供一种操作舒适的键盘具有重要的意义。
现有技术中常使用一种具有平整外观的没有断层的键盘面结构的键盘，该键盘通过固定在钢丝线上的挂钩压制键帽边角，通过挂钩的旋转实现键帽的升降。不使用按键时，通过钢丝旋转带动挂钩压下按键下沉到和键盘面持平位置，键盘面整体呈现为一个平面，提高了外观美感和消费者的手感。当使用按键时，挂钩反向翻转解除压力，键帽升起到所需高度。这样的结构可以保证即使是薄型电脑也可以有足够长的键程。但是制作上述键盘，需要使用高摩擦系数的材料及机构，而且所有按键都需要焊接钢丝线及挂钩，增加了零件数量，加大了整机重量及成本。
发明内容
有鉴于此，本申请提供一种薄型、按键行程较长、简化了整体结构且降低了制作成本的键盘组件。
还有必要提供一种应用如上所述的键盘组件的设备框架。

具体实施方式
为能进一步阐述本申请达成预定申请目的所采取的技术手段及功效，以下结合附图1-19及较佳实施方式，对本申请提供的键盘组件、键盘及电子设备的具体实施方式、结构、特征及其功效，作出如下详细说明。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中设置的元件。当一个元件被认为是“设置在”另一个元件，它可以是直接设置在另一个元件上或者可能同时存在居中设置的元件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请实施例提供一种设备框架，包括一键盘组件、一顶板及一底板。所述键盘组件包括一键盘基板、包括多个键帽的键帽阵列以及一包括多个与所述键帽一一对应的升降支架的升降支架阵列；每个键帽通过与之对应的所述升降支架与所述键盘基板连接。所述键盘基板与所述底板相连，所述键盘基板能够相对于所述底板滑动。所述底板包括与多个所述键帽一一对应的多个按键收容槽，每个所述按键收容槽具有一内凹斜面，所述升降支架位于所述按键收容槽内，所述升降支架的一端与所述内凹斜面抵持并能在所述内凹斜面上滑动。所述键盘基板与所述顶板相连，所述顶板与所述底板转动连接。在所述顶板相对于所述底板转动到第一设定位置的过程中，所述顶板带动所述键盘基板相对于所述底板移动从而使得每个所述升降支架在所述内凹斜面上沿第一方向滑动，使得每个所述升降支架下降，从而带动每个所述键帽下降。在所述顶板相对于所述底板转动到第二设定位置的过程中，所述顶板带动所述键盘基板相对于所述底板移动从而使得每个所述升降支架在所述内凹斜面上沿第二方向滑动，使得每个所述升降支架上升，从而带动每个所述键帽上升。其中，所述顶板转动到所述第一设定位置的方向与所述顶板转动到所述第二设定位置的方向相反。
这里的“第一设定位置”是指所述顶板相对于所述键盘基板的展开角度为0度时，也即是所述顶板闭合时所处的位置，“第二设定位置”是指所述顶板相对于所述键盘基板的 展开角度为90度时，所述顶板所处的位置。
由上述描述可以看出，本实施方式提供的升降支架能够实现一个功能：给键帽提供上升或下降的动力。升降支架在实现上述功能时，需要通过顶板、键盘基板及底板的配合来实现。顶板、键盘基板及底板可以采用不同的结构来实现，为了方便理解，下面结合附图以及具体的实施方式对其进行详细的描述。

其中，所述底板140还包括一个面向所述顶板110(当所述顶板110处于第一设定位置时)的键盘面42。当所述按键120下降至最低处时，所述键帽210低于或平齐于所述键盘面42。
本申请提供的键盘组件、设备框架及包括所述设备框架的电子设备，1)通过顶板110转动推拉键盘基板130平移，并利用升降支架220的凸角2271与底板140的按键收容槽41的内凹斜面411之间的挤压产生相对错动，实现升降支架220的纵向伸缩，带动键帽210的上升或下降，能够得到结构的运动性较稳定、薄型且键程较长的键盘组件；2)仅通过一组简单的机构(顶板110、键盘基板130及内凹斜面411)就可以实现所有键帽210的同时升降，从而简化了键盘组件及设备框架100的整体结构，降低了键盘组件及设备框架100的整体重量及制作成本；3)当顶板110处于第一设定位置(顶板110完全闭合)时，键帽210低于或平齐于底板140的键盘面42，从而使得键盘组件具有平整的键盘外观面，从而能够提高用户手感，增大产品差异化；4)采用摩擦系数小的垫片配合台阶状的限位件38对所述键盘基板130进行限位，不仅能够保证键盘基板130相对底板的运动精度，还可以保证键盘基板130与底板140间相对运动的顺滑，以提高用户体验；5)使用限位件38(台阶螺钉)作为限位结构，可以提高键盘组件的运动精度。
以上所述，仅是本申请的较佳实施方式而已，并非对本申请任何形式上的限制，虽然本申请已是较佳实施方式揭露如上，并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本申请技术方案内容，依据本申请的技术实质对以上实施方式所做的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
