Description

一种键盘及其组装方法 技术领域
本发明涉及电子产品技术领域，尤其涉及一种键盘及其组装方法。
背景技术
现今市场中，随着平板电脑行业的兴起，蓝牙键盘的市场需求也越来越大，且其使用功能、使用手感、产品厚度、生产效率及成本也随之要求越来越高。
技术问题
目前蓝牙键盘主要采用剪刀脚结构键盘和电阻式触摸结构键盘两种，剪刀脚结构键盘厚度一般在3.5 毫米~5.毫米之间，厚度较厚，在使用过程中，还可能将其键帽扣掉，影响其使用功能，且生产产品时，需要多个模具成型，但是模具成本产品的成本较高，其产品组装的效率也较低，难以满足市场的需求；电阻式触摸结构键盘厚度可以做到1.0 毫米~1.5 毫米，但使用者在使用时，没有按键的手感，不符合常规使用习惯，容易让使用者形成误操作，不被市场认可。
 技术解决方案
本发明的目的在于克服现有技术之缺陷，提供了一种键盘及其组装方法，实现产品厚度薄、使用手感好、生产成本低及组装效率高的优点。
本发明是这样实现的：一种键盘，包括：依次连接的面框、多连杆键帽板、金属弹片、软性线路板及底板，所述多连杆键帽板为自平衡一体式的多连杆结构，且在所述多连杆结构上固定设置有数个键帽，所述金属弹片为一体式结构，且在与所述键帽相对应的位置分别设有弧形凸起。
进一步地，所述面框上开设有数个与所述键帽相配合的缺口，且在所述面框下表面设置有数个胶柱，所述金属弹片、软性线路板及底板都开设有与所述胶柱相配合的孔。
进一步地，所述键帽的下端固定设置有支柱，所述支柱与所述金属弹片的弧形凸起相接触。
进一步地，所述底板为金属底板。
进一步地，所述多连杆结构包括一边框及数个连杆，所述连杆的形状与所述键帽相对应，所述连杆的两端与所述边框固定连接。
进一步地，一种键盘的组装方法，包括步骤1：将所述面框倒置安放在安装桌面上，再将所述多连杆键帽板沿所述面框缺口轴线方向放入所述面框内，使得所述键帽与所述面框缺口配合连接；步骤2：将所述金属弹片、软性线路板及底板依次倒置在所述多连杆键帽板下表面上，所述面框的胶柱依次穿过所述金属弹片、软性线路板及底板的孔；步骤3：加热所述胶柱，使其与所述底板熔合成为一体。
 有益效果
本发明具有的技术效果是：本发明提供了一种键盘及其组装方法，本键盘包括依次连接的面框、多连杆键帽板、金属弹片、软性线路板及底板，多连杆键帽板及金属弹片都为一体式，可以一次成型，减少了模具成本，并提高了生产组装的效率；另外，本发明键盘的结构代替了普通键盘的剪刀脚结构，使其结构简单化，从而其厚度可以做到3 毫米以下，满足了市场需求；其次，本发明的金属弹片为一体式结构，且在与键帽相对应的位置分别设有有弧形凸起，键帽的下端固定设置有支柱，支柱与金属弹片的弧形凸起相接触，使用过程中金属弹片受压力变形会产生段落感，既是手感，符合使用者的习惯，从而被市场认可。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1 为本发明一种键盘的一个实施例整体结构分解示意图；
图2 为图1 所示键盘的多连杆键帽板的局部Ⅵ放大平面示意图；
图3 为图1 所示键盘装配状态下的局部剖视结构示意图。
 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
如图1 至图3 所示，本发明实施例提供了一种键盘，包括依次连接的面框10、多连杆键帽板20、金属弹片30、软性线路板40 及底板50，所述多连杆键帽板20 为自平衡一体式的多连杆结构22，且在所述多连杆结构22 上固定设置有数个键帽21，所述金属弹片30 为一体式结构，且在与所述键帽21 相对应的位置分别设有弧形凸起31，多连杆键帽板20 及金属弹片30 都为一体式结构，分别可一体成型，减少了生产过程中的成本，及提高了组装效率，并且在使用过程中还防止了键帽21 被误扣掉，使之使用寿命更长久。
进一步地，如图1 至图3 所示，所述面框10 上开设有数个与所述键帽21 相配合的缺口11，且在所述面框10 的下表面设置有数个胶柱12，所述金属弹片30、软性线路板40 及底板50 都开设有与所述胶柱12 相配合的孔，所述键帽21 的下端固定设置有支柱211，所述支柱211 与所述金属弹片30 的弧形凸起31 相接触，所述底板50 为金属底板50。
进一步的，如图1 和图2 所示，所述多连杆结构22 包括一边框及数个连杆，所述连杆的形状与所述键帽21 相对应，所述连杆的两端与所述边框固定连接。
如图1 至图3 所示，本发明实施例提供的键盘的组装方法，包括步骤1：将所述面框10 倒置安放在安装桌面上，再将所述多连杆键帽板20 沿所述面框10 缺口11 轴线方向放入所述面框10 内，使得所述键帽21 与所述面框10 缺口11 配合连接，键帽21 正好嵌入面框10 的缺口11 内，使面框10 与多连杆键帽板20 紧密贴合；步骤2：将所述金属弹片30、软性线路板40 及底板50 依次倒置在所述多连杆键帽板20 下表面上，所述面框10 的胶柱12 依次穿过所述金属弹片30、软性线路板40 及底板50 的孔，定位准确，安装方便；步骤3：加热所述胶柱12，使其与所述底板50 熔合成为一体，因为胶柱12 为塑胶材料，加热后可熔化变形，从而固定在底板50 上，冷却后，因为热胀冷缩原理，会使整个键盘各部件之间贴合的更紧密、稳固；本发明实施例提供的键盘组装方法基于键盘结构的简单合理化，且多连杆键帽板20 及金属弹片30 都为一体式结构，分别可一体成型自动化生产，不仅节省了生产成本，而且在组装时更加的方便快捷，保证了产品的一致性，大大提高了生产及产品组装的效率。
在使用时，如图1 至图3 所示，通过手指按动键帽21，键帽21 下端的支柱211 抵触在金属弹片30 上的弧形凸起31 上，使弧形凸起31 受力变形接触到软性线路板40 产生信号传输给电脑，松开手指，通过多连杆键帽板20 上的多连杆结构22 自身的平衡弹力及金属弹片30 自身的弹力使键帽21 和弧形凸起31 都回复到原位，软性线路板40 停止发送信号；另外，人们在使用过程中往往不能准确的将手指按在键帽21 的中间位置，而采用本实施例键盘，当手指按在键帽21 的一个角212 进行施力时，对角线的另一个角213 就会受到面框10 的一个反力，面框10 的下裙边13 就会传力给键帽的上裙边214，同时多连杆键帽板20 上的多连杆结构22 也会给键帽21 一个反力，以保证键帽能够轻松不费力的上下运动；本发明实施例提供的键盘解决了产品厚度的问题，并且使用时会产生段落感，更容易让消费者所接受，而且本发明实施例提供的键盘在生产及组装过程中节省了成本，提高了效率，所以将会受到市场的青睐。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
