Description

按键模组 技术领域
本发明涉及按键，尤其涉及一种具有发光效果的按键模组。
背景技术
随着外观设计对消费者对吸引力越来越大，按键的设计也变得越来越多元化。其中的一种便是具有发光效果的按键。现有的一种发光按键的结构包括一个导光板以及多个LED灯，该多个LED灯均匀排布在导光板外侧，从而使得导光板的正面或内侧的光较为均匀。然而，此种结构中，位于外侧的LED灯为了达到出光均匀的效果，必需使用多个LED灯，导致此种结构显得较为浪费。
发明内容
本发明提供了一种需要较少光源的按键模组。
本发明一个实施方式提供了一种按键模组，包括操作件；电路板，具有用于感测该操作件上的触摸的图形；按键，设置于该电路板；导光元件，包括正面、相对的背面、位于该正面及背面之间的容置空间、开设于该背面的凹部、通过该正面将该容置空间连通至外部的通孔以及自该凹部内表面延伸至该正面的光路；其中，该操作件、电路板及按键依次收容于该容置空间，该操作件至少部分收容于该通孔，该按键抵顶该导光元件。
本发明另一个实施方式提供了一种按键模组，包括导光基座，其上开设有一个凹部；导光上盖，其与该导光基座相对设置并开设有一个通孔，还包括一个环绕该通孔的出光环面；操作件，其至少部分收容于该通孔； 及按键，其连接件至该操作件并抵顶该导光基座；其中，该导光基座及该导光上盖共同定义出一个自该凹部内表面延伸至该出光环面的光路，该光路的内径大于该出光环面的外径。
本发明中，设置于凹部的光源射出的光线将沿着导光元件定义的光路从凹部的内表面延伸至正面并射出。如此，本实施方式提供的按键模组仅需要一个光源便可，节省了所需光源的数量。

图5是本发明第二实施方式提供的按键模组的剖视示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合多个实施方式及附图，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不用于限定本发明。并且，其显示不代表本发明各元件的实际比例关系，仅做示意。
结合图1至图4，本发明第一实施方式提供的按键模组8包括操作件10、电路板20、按键30以及导光元件40。操作件10为一薄片，在本实 施方式中呈圆形薄片状，当然在其它实施方式中也可以是其它形状，可根据具体需求设计。电路板20具有用于感测操作件10上的触摸的图形22。该图形22可以是通过印刷电路板的制程方式制作而成，或者是通过ITO或碳纳米管等材料通过丝网印刷等其它方式形成的三角形、手指交叉形等形状的图形，不限制于具体的实施方式，只要能实现感测触摸功能便可。按键30设置于电路板20。导光元件40包括正面44a、相对的背面42a、位于正面44a及背面42a之间的容置空间46、开设于背面42a的并用于容置一个光源7的凹部42b、通过正面44a将容置空间46连通至外部的通孔44b以及自凹部42b的内表面42c延伸至正面44a的光路48。导光元件40可由常用的具有良好导光功能的导光板材料制成，凹部42b可根据具体的光源大小设置。操作件10、电路板20及按键30依次收容于容置空间46，操作件10至少部分收容于通孔44b，按键30抵顶导光元件40。
工作过程中，要实现按键功能时，直接按压操作件10后，操作件10将通过电路板20按压按键30，从而实现按压功能。按键30优选处于操作件10的中间部位，以使按压操作件10边缘各处时对按键30的压力一致。要实现触摸操作的功能时，则不必按压操作件10，直接在操作件10上划出想要的轨迹便可，该些轨迹将会被电路板20上用于感测触摸的图形22所感测，从而实现触摸功能。当在凹部42b处放置一个光源，比如LED灯后，光线将至少部分在导光元件40内发生全反射，从而沿着导光元件40定义的光路48从凹部42b的内表面42c延伸至正面44a，并从正面44a射出。如此，本实施方式提供的按键模组8仅需要一个光源便可，节省了所需光源的数量。必须指出的是，图中示出的光路48只是一个光线的具体示意图，实际上的光路应该是图4中导光元件40的剖视面。
具体地，导光元件40包括导光基座42及相对的导光上盖44。导光基 座42大致呈盘状，其底部包括上述背面42a及凹部42b，还具有一个背对背面42a的第一结合面(图未标)以及连接背面42a及第一结合面的侧面42d。导光上盖44大致呈环状，其包括上述正面44a及通孔44b，还包括背对正面44a的第二结合面(图未标)以及连接正面44a及第二结合面的侧面44c。第一结合面及第二结合面相互结合构成相互结合面，从而结合成整体的导光元件40。光路48穿过两个结合面而向正面44a延伸，如此，光路48包围容置空间46。
优选地，导光基座42及导光上盖44之间具有第一定位结构。在本实施方式中，该第一定位结构包括开设在导光基座42上的多个第一凹孔42e以及自导光上盖44的第二结合面向外凸出并容置在该多个第一凹孔42e内的第一凸柱44d。同理，优选地，操作件10与电路板20之间具有第二定位结构。在本实施方式中，该第二定位结构包括开设在电路板20上的多个第二凹孔24以及自操作件10向外凸出并容置在该多个第二凹孔24内的第二凸柱12。当然可以理解，上述两个定位结构中的凹凸方向也可以反过来，或者是其它方式，只要能起到定位效果即可。
优选地，导光上盖44定义出一个位于正面44a并环绕通孔44b的出光环面44e，导光上盖44的正面44a除了出光环面44e之外的表面以及其侧面44d、导光基座42的背面42b除了凹部内表面42c之外的表面及其侧面42d均设置有反光涂层。如此，可有效防止光线通过非预设出光的面射出导光元件40，提高出光环面44e的亮度。更优选地，导光元件40面向容置空间46的内表面也设置有反光涂层，即导光元件40除了出光环面44e及凹部内表面42c之外的表面均设置有反光涂层，如此，更进一步避免光线外射。
优选地，光路48的内径大于出光环面44e的内径，更优选地，光路 48的内径大于出光环面44e的外径。具体地，正如上所说，光路48是图4中导光元件40的剖视面，具有一定的宽度区间。本实施方式中导光元件40呈圆形，光路48在垂直于图4的剖视平面的面上的剖视图是呈圆环形，因此，光路的内径对应的是图4中的距离D1。出光环面44e的内径指的则是图中的距离D2，外径指的是图中的距离D3。在光路48的内径大于出光环面44e的内径的情况下，光路将有向按键模组8的中部出射的效果，有利于光线在操作件10上方汇聚。更优选地，出光环面44e的内侧向导光基座42倾斜，此特征更进一步加强汇聚效果。
请结合图5，其为本发明第二实施方式提供的按键模组9的剖视示意图，其与第一实施方式的按键模组8的区别主要在于，不包括电路板20，按键30抵顶操作件10及导光基座42。此时也可实现上述按键功能及节省光源的效果。即是说，第二实施方式的按键模组9包括导光基座42，其上开设有一个凹部42b；导光上盖44，其与导光基座42相对设置并开设有一个通孔44b，还包括一个环绕通孔44b的出光环面44e；操作件10，其至少部分收容于通孔44b；及按键30，其连接至操作件10并抵顶导光基座42；其中，导光基座42及导光上盖44共同定义出一个自凹部42b的内表面42c延伸至出光环面44e的光路48(如图4)，光路48的内径D1(如图4)大于出光环面44e的外径D3(如图4)。优选地，按键30为带按键式旋转编码器，如此，旋转按键30可实现上述触摸图形22所能实现的感测旋转的功能。
以上所述仅为本发明的较佳实施方式而已，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、等同替换和改进等，均应包含在本发明的保护范围之内。
