Description

说 明 书 一种笔记本电脑发光键盘的导光线路板模组
[0001]
技术领域
[0002] 本发明涉及一种笔记本电脑领域， 具体涉及一种笔记本电脑发光键盘中的导光 线路板模组。
背景技术
[0003] 现有笔记本电脑键盘如果需要键盘发光， 其按键作用的线路板与提供发光电源 的线路板及导光板是分离的， 按键作用的线路板大多为柔性印刷线路板， 发光电源的 线路板大多采用金属柔性线路板（FPC)加上发光光源（ 贴片 LED灯）再加上导光板 等辅助材料组合在一起， 导光板附着于键盘基材背面， 而键盘中具有按键功能的印刷 柔性线路板附着于键盘金属基材上面， 如图 1所示： 现有笔记本电脑发光键盘中线路 板及导光板结构为：基板 1的上面设有下层线路板 2，下层线路板 2上面设有隔片层 3， 隔片层 3上面设有上层线路板 4， 基板 1的下面设有导光板 5。 如此则需要生产线路板 及导光板两种材料， 不仅生产成本较高， 而且增加了键盘的厚度， 因需给发光光源单 独供电， 电脑主板还需要为其提供电源和连接位置， 也不同程度上占用了主板的设计 空间。 为此， 需研发将金属柔性线路板、 印刷柔性线路板、 导光板三者结合在一起的 产品， 此即为导光线路板模组。
发明内容
[0004] 本发明的目的是为了克服现有发光键盘在键盘厚度上的缺陷， 解决笔记本电脑 实现超薄型设计的空间限制， 提供一种能实现笔记本电脑键盘发光同时不增加键盘厚 度， 并可节省工序及大量的辅助材料从而降低制造成本的一种导光线路板模组。
[0005] 本发明采用的技术方案是： 一种笔记本电脑发光键盘的导光线路板模组， 包括 三层或两层结构；
所述三层结构包括自上而下依次设置的上层线路板、 隔片层和下层线路板， 所述上层 线路板中粘有发光 LED, 所述隔片层或下层线路板为导光板， 所述下层线路板上面印 刷有起键盘按键作用的线路；
所述两层结构包括上层线路板和下层线路板， 所述上层线路板中粘有发光 LED, 所述 下层线路板为导光板， 所述下层线路板上面印刷有起键盘按键作用的线路。 说 明 书
[0006] 所述下层线路板与上层线路板相结合起来， 起到键盘各按键的功能作用， 当上 层线路板与下层线路板组合后， 上层线路板中 LED将被镶入到导光材料的沉孔中为发 光键盘提供光源。
[0007] 作为优选， 所述导光线路模组设置于键盘基板上面， 导光线路模组上设置与键 盘按键避位的机构孔及容纳所述 LED的沉孔。
[0008] 作为优选， 所述导光线路模组设置于键盘基板下面， 导光线路模组上仅设置配 合组装在电脑上的螺丝孔之类的避位孔及容纳所述 LED的沉孔， 不设置配合键位机构 的机构孔。
[0009] 作为优选， 所述基板采用铝板或铁板或合金板。
[0010] 有益效果： 本发明将导光板与线路板合为一体， 在导光板上设有实现按键功能 的导电线路， 并由于上层线路粘有 LED, 此 LED在组装后会镶入导光材料中， 故此导 光线路板模组可实现导电与导光双重效果， 并于导光线路板正面增加反光层和遮光层， 在反面增加反光层， 并直接利用本体的可发光元器件直接为导光板提供发光光源， 如 此可达到发光键盘的效果； 由于线路与导光材料结合， 可以避免为获得笔记本电脑键 盘发光功能所增加出来的笔记本电脑厚度， 从而为实现笔记本电脑超薄设计在键盘零 组件上提供保证。
