本发明提供一种光电发热键盘，包括基座，导光板与按键，其中导光板的四周包围有向导光板内部发射光线的灯条；按键从上至下设有吸能层、导光层与反射层，各层厚度均不小于导光板的厚度，其中吸能层表面制成黑色，导光层由透明材料制成，并将接受到的光线通过按键内部的竖直通道导至按键顶部，以形成按键背光，反射层表面制成镜面；基座内以弹性结构分别支撑导光板与按键，使按键在自然状态下时，导光板正对导光层；按键的顶端横向延伸形成帽沿，使按键下压时能够通过帽沿带动导光板下沉，其中导光板下沉至极限时，导光板正对处于自然状态下的按键的反射层。该键盘不仅能够提供按键背光，同时能以较小的成本温暖手指。

Description

光电发热键盘
技术领域
本发明涉及一种计算机输入设备，特别地，涉及一种键盘。
背景技术
计算机在生活中已经得到广泛的应用，人们时常使用键盘对计算机输入讯号；然而在寒冷天气下使用键盘时，由于手部暴露在外，时间一长便会寒冷僵硬，影响工作效率。
另一方面，为了追求个性美观，许多键盘采用了背光设计，然而此类发光设备仅作装饰用途，其功能较为局限，硬件设置较为浪费。
发明内容
针对上述问题，本发明的目的在于提供一种光电发热键盘，该键盘不仅能够提供按键背光，同时能以较小的成本温暖手指。
本发明解决其技术问题所采用的技术方案是：该光电发热键盘包括基座，导光板与按键，其中所述导光板上开有与所述按键相匹配的孔洞使按键穿过，且导光板的四周包围有向导光板内部发射光线的灯条；所述按键从上至下设有吸能层、导光层与反射层，各层厚度均不小于所述导光板的厚度，其中所述吸能层表面制成黑色，所述导光层由透明材料制成，并将接受到的光线通过按键内部的竖直通道导至按键顶部，以形成按键背光，所述反射层表面制成镜面；所述基座内以弹性结构分别支撑所述导光板与所述按键，使所述按键在自然状态下时，所述导光板正对所述导光层；所述按键的顶端横向延伸形成帽沿，使所述按键下压时能够通过所述帽沿带动所述导光板下沉，其中所述导光板下沉至极限时，导光板正对处于自然状态下的按键的反射层。
作为优选，该键盘内还包括有所述灯条的功率调节模块，所述功率调节模块在键盘具有电讯号输出时，将所述灯条的功率调节至最大，否则将其灯条功率调节至最小；从而使按键下压时，形成瞬时高热效应，增强手指的温度感。
作为优选，所述导光板的上下两面制成对内的镜面，以约束内部的光线，避免光线通过所述导光板的上下两面泄露出外界，从而提高光线的利用效率。
作为优选，所述弹性结构为弹簧或硅胶凸起。
本发明的有益效果在于：该光电发热键盘处于自然状态下时，灯条发出的光线经导光板，通过各按键的导光层输出至外界形成按键背光；而当某一按键被按下时，导光板正对该按键的吸能层，并以帽沿带动导光板下沉，使其余按键的反射层与导光板正对，以使灯条发出的全部光线被按下按键的吸能层吸收，进而转化为热量，温暖与该按键接触的手指。
附图说明
图1为本光电发热键盘一个实施例处于自然状态下的结构示意图。
图2为图1所述实施例按下按键时的结构示意图。
具体实施方式
下面结合附图和实施例对本发明进一步说明：
如图1、图2所示的实施例中，该光电发热键盘包括基座1，导光板2与按键3，其中所述导光板2上开有与所述按键3相匹配的孔洞使按键3穿过，且导光板2的四周包围有向导光板2内部发射光线的灯条5；所述按键3从上至下设有吸能层31、导光层32与反射层33，各层厚度均不小于所述导光板2的厚度，其中所述吸能层31表面制成黑色，所述导光层32由透明材料制成，并将接受到的光线通过按键3内部的竖直通道34导至按键3顶部，以形成按键背光，所述反射层33表面制成镜面；所述基座1内以弹性结构4分别支撑所述导光板2与所述按键3，使所述按键3在自然状态下时，所述导光板2正对所述导光层32；所述按键3的顶端横向延伸形成帽沿35，使所述按键3下压时能够通过所述帽沿35带动所述导光板2下沉，其中所述导光板2下沉至极限时，导光板2正对处于自然状态下的按键3的反射层33。
另外，该键盘内还包括有所述灯条5的功率调节模块，所述功率调节模块在键盘具有电讯号输出时，将所述灯条5的功率调节至最大，否则将其灯条5功率调节至最小；从而使按键3下压时，形成瞬时高热效应，增强手指的温度感。
另外，所述导光板2的上下两面制成对内的镜面，以约束内部的光线，避免光线通过所述导光板2的上下两面泄露出外界，从而提高光线的利用效率。值得一提的是，即便不设置所述镜面，由于导光板2内部的全反射效果，仍然可以将绝大多数光能约束于导光板2内部。此外，所述弹性结构4可以为弹簧或硅胶凸起。
另外，对于所述键盘的电路结构，可采用常规结构，即在所述按键3底部设置压块30，而所述基座1内底部铺设柔性双层电路印刷层6，各按键3的压块30对应于该柔性双层电路印刷层6的各个电路节点，按键3下压时，压块30压住电路节点，使其导通，从而形成与该按键3对应的电讯号。
上述光电发热键盘处于自然状态下时，灯条5发出的光线经导光板2，通过各按键3的导光层32输出至外界形成按键背光；而当某一按键3被按下时，导光板2正对该按键3的吸能层31，并以帽沿35带动导光板2下沉，使其余按键的反射层33与导光板2正对，以使灯条5发出的全部光线被按下按键3的吸能层31吸收，进而转化为热量，温暖与该按键接触的手指。
以上所述仅为本发明的较佳实施例，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，均应包含在本发明的保护范围之内。
