Description

一种更符合人体工程的计算机通用键盘 技术领域
本实用新型涉及计算机技术领域， 一种更符合人体工程的计算机通用键 盘。
背景技术
说
一、目前台式计算机键盘与笔记本计算机键盘在按键布局排列方面存在一 定差异。 台式计算机普遍釆用的是 104键盘， 其在布局方面， 键盘被分为四个 区域， 它们分别是打字字母键区， 编辑控制键区书、 副键区和功能键区， 布局过 于分散， 整体尺寸较大， 存在以下不足：
1、 在不同键区交换操作时， 手指及手的移动跨度较大， 容易造成人体疲 劳及击键误差。
2、 总体尺寸较大， 不利于桌台面的使用， 影响桌台面的其它使用功能。
3、 键盘在习惯放置情况下， 或者右侧位置受限制的情况下， 在身体正对 屏幕打字时， 两手不能与身体的左右对称平面对称， 而是偏向身体的左侧， 这 种现象不符合人体工程学要求。 对身体健康不利， 也不利于提高操作效率。 二、对于笔记本计算机来说， 由于其外形尺寸的限制， 其键盘采用集中式 布局， 与台式计算机相比， 打字键区与功能键区没有太大变化， 只是集中了， 但是编辑键区排位则有一定的变化，不同品牌笔记本计算机之间键盘也存在排 位差异，笔记本计算机键盘普遍取消了独立副键区，而将其数字与符号键功能 设置在打字区某些字符键的多档功能上，总体来说笔记本计算机键盘由于受尺 寸小的限制， 按键设置有些牵强， 显得有些无序， 操作上自然有些不便， 这是 公认的事实。 由于笔记本与台式计算机的键盘在布局方面存在一定的差异，人们在互换 使用笔记本计算机和台式计算机时对键盘感觉很不适应， 影响人们的操作使 用。 三、 笔记本键盘和台式计算机键盘都存在以下不足：
1、 空格键普遍占用底行中心区域 5到 7个普通键距位置， 因此空格键成 为 最 "奢侈"的按键， 极大浪费资源， 存在以下不足：
1)、增大了其它按键的边缘化程度，不利于操作，也不利于减小键盘尺寸。
2)、使用大拇指的功能没有得到充分发挥，大拇与其它四指中任何一指的 配合都比四指之间任何两指的配合灵活的多， 由于空格键占用了太大位置，挤 占了更适合于大拇指操作的按键排放的位置，影响了有效的大拇指使用率， 即 影响人机系统工程效率。
2)、 Backspace键， 也是打字时常用的键， 不在手指容易控制的范围， 操 作时不太方便。
3)、 Shift键（上当键）也是常用键， 放在打字区两边由小拇指控制再与 其它手指配合完成操作，我们都知道小拇指是所有手指中力度最小的，而且与 其它手指的配合也不够灵活，所以 Shift键的设置不符合人体工程学要求，操 作时不但容易造成小拇指疲劳， 还影响操作效率，
4)、打字区键位整体组合不够合理，左手控制键数较少，右手控制键较多， 因此右手操作范围较大， 手指移动跨度较大， 不但容易造成右手疲劳， 还影响 整体打字效率。
发明内容 本实用新型的目的就在于使笔记本计算机键盘与台式计算机键盘实现按 键统一位置排列， 便于互换使用， 更适于人们的操作习惯， 最大程度的发挥人 机功能，提高工作效率， 减小键盘整体尺寸。从而提供一种更符合人体工程的 计算机通用键盘。
本实用新型的目的可通过以下措施来实现：
本实用新型包括键盘本体,所述键盘本体上两个 Shift按键分别设置在底 行紧邻空格键的两侧。
本实用新型中键盘本体上各键分区排位组合成三个区域： （1)、 位于键盘 中部及左部的以打字键区为主而组成的主键盘区； （2)、 位于键盘上部第一行 以功能键区为主而组成的功能键区 ;1 (3)、 位于键盘右部以编辑键区为主而组 成的副键盘区； 另外， 为方便左手使用习惯者的操作， 也可将副键盘区及副键 盘区上方的键位移置到主键盘区的左部， 同时， 其他相关键位做相应调整。键 盘本体中的 Enter键设置在所述主键盘区的右下脚。 键盘本体上 + - * / 四个 常用数运算符号键依次设置在从键盘底行向上数第五行的最右端四个键位上。 键盘本体上在从底行向上数第二行的最左端字母键的左侧设置一个符号键。在 从底行向上数第三行的最左端字母键的左侧设置一个符号键；在从底行向上数 第四行的最左端字母键的左侧设置一个符号键。 键盘本体上 Num lock键设置 在键盘底行， Num lock键左边与 Enter键相邻， Num lock键右边和上边与编 辑键相邻。键盘本体上 Backspace键设置在从底行向上数第四行内，其右侧与 编辑键区相邻。 键盘本体上主键盘区由 47个字符键、 一个 Backspace键、 一 个 Tab键、 一个 Caps Lock键、 一个 Start键、 一个 Application键、 一个 Enter键、 一个空格键、 两个 Shift键、 两个 Alt键、 两个 Ctrl键共 60个按 键排成五行并且每一行不超过十三个按键组成，设置在副键盘区的左侧；副键 盘区由 10个编辑键与数字键可相互转换的键、 一个 +号键、 一个 -号键、 一个 *号键、 一个 I号键、 一个 . 号键、 一个 Num lock键共 16个按键共 排成五行组成， 设置在主键盘区的右侧； 功能键区由 12个功能键、 一个 Esc 键、 一个 Prtsc Sys Rp键、 一个 Scroll Lock键、 一个 Pause Break键共 16 个按键共排成一行组成，设置在主键盘区和副键盘区的上侧。键盘本体上空格 键长度为 35mm- 50 mm, 当然， 也可采用其他合适的尺寸。
本实用新型由于采用上述键盘布局结构， 使之具有以下效果： 1、 与目前主流台式计算机键盘（104键盘）相比， 整体尺寸减小了很多， 特别是左右长度尺寸只相当于 104键盘的 7/10左右， 在使用时两手及手指的 移动跨度大大减小了， 使打字的速度更快了， 操作也更加轻松了。另外也使键 盘的摆放更加自如， 减少了桌台面的占用。
2、 与目前绝大多数笔记本计算机键盘相比， 它增设了右侧小键盘区的功 能， 使用起来人们感到很方便， 操作更加自如。
3、 当大拇指按住底行的 Shift键时， 同手的其它手指很容易而且快捷底 击打到任何一个按键， 要比以往用小拇指按边侧的 Shift键灵便的多。
4、 若笔记本和台式计算机都配装此键盘, '人们在互换使用时就不会感到 不适应了。
5、 Enter键的位置更加合理， 打字时用小拇指敲击很方便， 在使用数字 小建盘区时， 敲击 Enter键也很方便。
6、 指示灯的设置更容易观察， 以便更好的指导人们操作。
