Combined computer keyboard and key layout of the keyboard

Abstract

The invention provides a combined type computer keyboard and a key code distribution of the keyboard. The keyboard includes a left hand part (1), a right hand part (2), an assistant part (3) and an end board (4), the key code distribution also includes a left key area (11), a right key area (21) and an assistant key area (31). The keyboard and key code distribution have characteristics that each part is corresponding to each key area, each part is separate undependent, wherein, one part top is equipped with an output line (5) linked with a computer host, a hardware linkage mechanism (6) and an information conduction device (7) interface combined with other parts are set among various parts. The keyboard and key code distribution have advantages that the part can be combined freely according with user's favour, distance between the left hand part (1) and the right hand part (2) can be pulled by the assistant part (3), specially assistant keyboard part can be interfaced, word key code distribution shows reverse 'v' shape and acclimates flexible direction of the human body finger.

Description

technical field [0001] The invention relates to a computer keyboard, in particular to a combined computer keyboard, and to a key code layout suitable for the keyboard. Background technique [0002] The popularization and application of computers have spread to every corner of the earth, and all walks of life cannot do without its help. Inputting commands with a keyboard is still the main way of man-machine dialogue. Although everyone is familiar with and used to the traditional computer keyboard, but still can feel its many fly in the ointment: [0003] ——The left and right keypads of the current traditional keyboard are next to each other. When typing, the hands are squeezed together, and there is zero distance contact, which makes the operator put his chest and back, which is not only easy to fatigue, but also hinders the health of the heart and lungs; [0004] ——As we all know, when the human body sits in front of the computer desk, the direction of stretching and bendin...

AI Technical Summary

Problems solved by technology

[0003]——The left and right keypads of the current traditional keyboard are close to each other. also impairs cardiorespiratory health;

[0004]——As we all know, when the human body sits in front of the computer desk, the direction of stretching the fingers is from the outside to the inside, and the hands are stretched upwards in the shape of an "eight", while the letter keys of the traditional keyboard They are arranged from bottom right to top left, and the left-handed keys are extremely inconvenient, so most people can only work diagonally to the keyboard;

[0005]——The small number keys and direction keys of traditional keyboards are located on the right side, although it is convenient for right-handed operation, it is not conducive to sharing with "left-handed" people;

[0006]——Many professional disciplines, calculation symbols and program instructions of engineering calculations cannot be directly input from traditional keyboards, and traditional keyboards do not leave a platform for developing new key codes and interface

[0007] Chinese Invention Patent No. 2006100340564 authorized on September 12, 2007 is a "freely adjustable ergonomic keyboard", including: left keyboard, right keyboard and between them The free rotation adjustment device of the present invention, the left and right keyboards are freely rotatable and connected, although this invention can separate the distance between the two hands, it can also improve the direction of the left keyboard through rotation, but because the keyboard does not have an auxiliary keyboard (small numeric keypad) at all, in the practical range has great limitations;

[0008] Chinese Invention Patent No. 200610025157.5 "Computer Keyboard Technology for Construction Engineering Quantity Calculation Software" authorized by the announcement on October 3, 2007: designed a dedicated engineering quantity calculation software The keyboard can solve the data input problem that the traditional computer is not suitable for engineering quantity calculation software, but the ordinary keyboard must be withdrawn from the host computer to allow the interface to be inserted into the special keyboard;

[0009]A Chinese invention patent No. 2008100893665 authorized on October 22, 2008, a "folding keyboard with a numeric keypad", proposes a folding keyboard, which is limited to The numeric keypad, and a folding line is located between the edge of the standard continuous space bar and the edge of the numeric keypad. This invention only converges 1 / 2 the overall length and size of the keyboard by folding, and there is no improvement in the key code layout. And the canine teeth are staggered at the break, not aligned, and the structure is complex and difficult to process
