Description

Wave-shaped key computer keyboard

Technical Field

The utility model relates to the technical field of computer keyboards, in particular to a wavy key computer keyboard.

Background

For a long time, the plane shape of the computer keyboard and the keys thereof and even the heights of the keys always adopt a traditional mode, namely, the key horizontal heights of the computer keyboard adopt the same height without the change of the heights. The long-time use easily causes fatigue of fingers, the use comfort is reduced, and misoperation can be caused to a certain extent. Thereby creating an deficiency in operational use of the keyboard.

Through searching, someone performs functional modification and upgrade on the computer keyboard, and applies for an utility model patent named as a computer keyboard capable of fingerprint identification (patent number CN 202120944887.5). The fingerprint identification and structure improvement are mainly carried out on the key assembly from the aspect of safety of the computer keyboard, so that a non-computer attribution cannot carry out key operation, and only the computer attribution can carry out key operation, thereby further improving the privacy and safety of the computer.

The keyboard only solves the problem of safety, but cannot solve the problems of comfort of hand operation and further reduction of misoperation rate, especially the problems that five fingers of a person are different in length, and index finger, middle finger, ring finger and little finger which are frequently used for computer keyboard operation are different in length, basically the ring finger is slightly shorter than the index finger and the middle finger, and the little finger is slightly shorter than the ring finger. When the keys of the computer keyboard are positioned on the same horizontal plane, the computer keyboard can be horizontally arranged on the keyboard when the computer keyboard is operated by hands, so that ring fingers and little fingers are suspended, fatigue feeling of the fingers can be generated after the computer keyboard is operated for a certain time, and operation errors are easily caused after the fingers are tired.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a wavy key computer keyboard, which solves the problem that the computer keyboard in the prior art provided in the background art can feel tired when being used for a long time.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: a wavy computer keyboard comprises a keyboard main body, wherein a reference area, a left-hand little finger control area, a left-hand ring finger operation area, a right-hand little finger operation area, a small keyboard right-hand ring finger operation area and a small keyboard right-hand little finger operation area are arranged on the keyboard main body;

the left-hand little finger control area, the left-hand ring finger operation area, the right-hand little finger operation area, the small keyboard right-hand ring finger operation area and the small keyboard right-hand little finger operation area form wave forms with different heights on the key surface.

Preferably, the key in the left finger small-finger operation area is higher than the height of the reference area 5 MM;

the key in the left-hand ring finger operation area is higher than the height of the reference area 3 MM;

the key in the right-hand ring finger operation area is higher than the height of the reference area 3 MM;

the key in the right finger small finger operation area is higher than the height of the reference area 5 MM;

the key in the right-hand ring finger operation area of the small keyboard is higher than the height of the reference area 3 MM;

the keys in the right-hand finger pad increase by a height of 5 MM.

Preferably, the contact surface of the keyboard button and the finger is provided with a concave radian.

The utility model provides a wavy key computer keyboard, which has the following beneficial effects:

1. according to the utility model, the operating comfort of the computer keyboard can be economically and conveniently improved, and the fatigue caused by operating the computer keyboard for a long time by hands can be effectively relieved.

2. The utility model can well solve the problem that the computer keyboard is tired after being operated for a long time by hands, and the operation error is easy to cause.

3. In the utility model, the height of the keys of the original common computer keyboard on the same horizontal plane is changed, the keys are designed into a wave shape, the vision is improved, and the aim of beautiful appearance is achieved.

Drawings

FIG. 1 is a diagram showing the distribution of the finger operating area of a computer keyboard according to the present utility model;

FIG. 2 is a schematic diagram of the front structure of a computer keyboard according to the present utility model.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1 to 2, the present utility model provides a technical solution:

a wavy computer keyboard key is characterized in that the key is highly modified according to ergonomics, so that the key of each finger operation area is consistent with the length of fingers, and the keys of the operated (2) (3) (5) areas are heightened by 3MM to adapt to the ring fingers because the ring fingers are slightly shorter than the middle fingers; the keys in the areas (1) (4) (6) are operated to be increased by 5MM to adapt to the little finger because the little finger is shorter than the middle finger.

The wavy computer keyboard can form a concave radian on the key surface of the original common keyboard, has slightly higher sides and slightly lower middle parts, is convenient to operate, has layering sense, is more attractive, does not change the basic structure and the material texture of the keyboard, and does not increase the production cost of manufacturers.

Working principle: the keys on the keyboard of the general computer correspond to the operation areas of fingers respectively, the heights of the keys in the five areas (7), 8,9, 10, 11, 12, 13) are taken as the reference heights according to the prior art, and the heights of the keys in the other areas are adjusted, namely the heights of the keys in the areas (2), 3, 5) are increased by 3 MM; the height of the keys in the areas (1) and (4) is increased by 5MM, and the whole key surface of the keyboard forms wave-shaped surfaces of +5MM, +3MM, 0, +3MM, +5MM, 0, +3MM and +5MM, thereby completely adapting to the characteristics of different lengths of fingers of a human body and achieving the aim.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
