Human engineering keyboard

Technical Field

The invention belongs to the technical field of human engineering, and particularly relates to an ergonomic keyboard.

Background

With the rapid development of IT technology, computers have become an indispensable tool in human life, which brings fast operation, accurate calculation and convenient management modes. The updating speed of the computer is very high, and the keyboard and the mouse are continuously updated as input devices for man-machine interaction. However, most keyboards on the market at present do not meet the requirements of high efficiency and health and comfort of people in a man-machine system. At present, the key positions of the keyboard are mostly distributed in a straight line, so that the wrists of both hands of each key can be smoothly operated by fingers in the use process, and the wrists are in a state of bending towards two sides, so that the wrists are extremely tired, and the wristlet syndrome is caused by long-term use. Meanwhile, when a user inputs information through the keyboard and the mouse, the right hand needs to move back and forth between the keyboard and the mouse at any time, and the activity of the right wrist is greatly different from that of the left hand, so that the right wrist is extremely easy to fatigue and is extremely easy to damage after long-term use.

Disclosure of Invention

Based on the problems mentioned in the background art, the invention provides an ergonomic keyboard, which is used for solving the problems that the wrists of the hands are in a bending state to two sides for a long time and are easy to fatigue when the keyboard and the mouse are used at present, and the wrists of the right hand are easily fatigued due to the fact that the wrist activity is switched back and forth between the keyboard and the mouse at any time.

The technical scheme adopted by the invention is as follows:

the utility model provides an artificial engineering keyboard, includes main part dish and button, the main part dish includes upper cover, bottom, PCB board, locating plate and sandwich pad, the button includes key cap and axis body, the button includes main keyboard district, main control area, numeric keyboard district and functional area, the main part is set up at the dish middle part and is cut apart the breach, cuts apart the breach and is the V style of calligraphy and all is equipped with the fillet in individual corner. The main keyboard area is divided into a left key area and a right key area by a dividing notch, wherein a Ctrl key and a Shift key in the right key area are positioned at the left lower part, an Alt key is positioned at the right lower part, the use frequency of the thumb is improved, the use frequency of the thumb is reduced, meanwhile, the distance between finger keys is reduced, the finger force application habit is more met, and the use comfort is improved; while the Ctrl key in the left keypad is still located at the lower left to preserve the existing usage habits. The key positions in the left key area and the right key area are obliquely arranged towards the segmentation notch, the left hand and the right hand can adapt to the key positions without bending the wrist to two sides when the left key area and the right key area are operated respectively, the main control area is positioned above the segmentation notch, the functional area is positioned at the top end of the keyboard interface, the digital keyboard area is positioned at the right end of the keyboard interface, the main body disc is provided with a left mouse key, a right mouse key and a track ball at the segmentation notch, the left mouse key is positioned at the left opening part of the segmentation notch, the right mouse key and the track ball are positioned at the right opening part of the segmentation notch, the left mouse key, the right mouse key, the track ball and the track ball are all connected with the PCB board.

Based on the technical scheme, the invention also improves the following steps:

further, each row of keys in the left key area and the right key area are distributed in an arc shape. Because each fingertip is distributed in an arc shape when the fingertips with different finger lengths fall in the same plane, the key positions distributed in the arc shape can be operated better.

Further, the Backspace key is located at the upper left of the right keypad and the Spacebar key is located at the lower right corner of the left keypad. The Backspace key and the Spacebar key are used as common keys, the Backspace key can be positioned by stretching the index finger or the middle finger of the right hand to touch the wrist without bending, and the Spacebar key is positioned by the thumb of the left hand to touch the wrist for convenient use.

Further, the upper cover is provided with an inclined plane at the dividing notch, and the left mouse button, the right mouse button and the track ball are arranged on the inclined plane. The left mouse button and the right mouse button are positioned on different planes with the keys in the main keyboard area, so that the keys are not easy to be touched and pressed by mistake when being tapped, and the track ball is positioned on the inclined plane, so that the height can be reduced under the condition that the leakage area of the track ball is not reduced, and the track ball can be better operated by the thumb of the right hand.

Further, the bottom cover is detachably provided with a hand-held inclined table. A supporting point is provided for the wrist through the hand-held inclined table, fatigue and ache of the wrist caused by long-time operation are avoided, and the using comfort degree is improved.

Further, the bottom cover is provided with a bracket capable of being accommodated. The inclination angle of the keyboard can be changed through the storage bracket so as to meet the use habits of different users.

Further, equal number keys are additionally arranged in the numeric keyboard region. People with larger use requirements on the numeric keyboard region are inputting information, and when an equal number is required to be input, the people do not need to jump back and forth between the numeric keyboard region and the main keyboard region, so that the wrist activity can be reduced, and the input efficiency can be conveniently improved.

Further, the equal number keys are positioned at the lowest part of the numeric keypad region and are zero-offset from the numeric keys. Outside the matrix range formed by the keys in the prior numeric keyboard region, the operation of key positions in the prior numeric keyboard region is not easy to interfere.

The invention has the beneficial effects that:

1. the main keyboard area is divided into a left key area and a right key area, and the inclined arrangement of key positions can be better suitable for the operation of two hands, so that the wrists of the two hands do not need to bend towards two sides for a long time, and the wrists are not easy to fatigue;

2. the keyboard is integrated with the mouse function, the left thumb of the left hand operates the left key of the mouse, the right thumb of the right hand operates the right key of the mouse and the track ball, the index finger or the middle finger of the right hand can be stretched to operate the roller key, the right hand can not move greatly when the keyboard and the mouse are operated, the problem of huge difference of the activity of the two hands can not occur, and the right hand is not easy to fatigue.
