Abstract

A keyboard comprises a keyboard body. A circuit board is arranged inside the keyboard body, a plurality of diaphragms are arranged at the positions with certain distance from the circuit board, a plurality of buffer portions are arranged on the lateral surface of one optional diaphragm, a keycap is arranged above the optional diaphragm, an extension portion extending downwardly is arranged on the bottom surface of each keycap so as to abut to the corresponding diaphragm downwardly, and the top surface of the diaphragm and the circuit board are conducted. When each keycap is pressed downwardly and the lateral surface of the corresponding diaphragm is bent and transformed, spring-back force of each keycap can be reduced, and accordingly the keyboard can be used by a user in a more labor-saving manner.

Description

Keyboard

Technical field

The utility model relates to a kind of keyboard, when referring to a kind of use especially than the labour-saving keyboard.

Background technology

On the market keyboards of seeing mainly contain mechanical type and diaphragm type two big classes more, and wherein, to have when knocking feel comparatively comfortable because of it for thin film type keyboard, and generally speaking less than the knock volume of mechanical type keyboard advantage, become the main flow on the market.See also shown in Figure 8, existing thin film type keyboard, mainly comprise a keyboard body, the inside of keyboard body is provided with circuit board a, circuit board a is provided with a plurality of hollow membrane b, the top of arbitrary film b is provided with a keycap c, and the bottom surface of this keycap c is provided with an extension d who extends downwards, to compress film b downwards.Thus, when the user pushed arbitrary keycap c downwards, film b made end face and the circuit board a conducting of film b, and to be presented on the screen with the signal output that will knock because of stressed flexural deformation.

Existing keyboard in design; usually can be according to general computer user's demand; so key journey fixed distance between circuit board a and extension d; do not consider especially and need a large amount of working clans that use computer in routine duties; the user demand that it continues and knocks keyboard continually; make this type of user behind long-time use keyboard, be easy to generate the sequelae that hand is ached.

Moreover, computer game is one of main purposes of computer, feel when the general computer user of computer game player and even e-sports entrant more pays attention to keyboard and knocks, and the reaction velocity of keyboard, the key journey distance of existing keyboard is longer, and is unfavorable for that the computer game player uses when playing computer game.

In view of this,, make keyboard can not only knock keyboard more effortlessly, and more comfort feel arranged when using in order to improve above-mentioned shortcoming, the designer long-pending for many years experience and constantly research and development improve, generation of the present utility model is arranged then.

Summary of the invention

Fundamental purpose of the present utility model is providing a kind of strength that can reduce the keycap resilience, makes the user be able to when knocking than the labour-saving keyboard.

Secondary objective of the present utility model can have more comfortable feel providing a kind of when knocking, make the user be able to keyboard more flexibly when the different keyboard instruction of input.

For reaching the purpose of above-mentioned utility model, the keyboard that the utility model is designed, comprise: a keyboard body, its inside is provided with a circuit board, distance on this circuit board is provided with a plurality of hollow membrane, the top of arbitrary film is provided with a keycap, the bottom surface of this keycap is provided with an extension that extends downwards, to compress film downwards, make the end face and the circuit board conducting of film, the side of this film is provided with and a plurality ofly can presses down and make edgewise bend when distortion of film reduce the buffer part of keycap resilience strength at keycap.

During enforcement, this buffer part can be the otch or the polygonal opening of cross sections, く font, and equally spaced is located on the side of film.

Description of reference numerals: 1-keyboard; 2-keyboard body; The 21-circuit board; The 22-film; The 221-buffer part; The 23-keycap; The 231-extension; The a-circuit board; The b-film; The c-keycap; The d-extension.

Embodiment

See also shown in Fig. 1 to 3 figure, it is the preferred embodiment of the utility model keyboard 1, comprises a keyboard body 2, a circuit board 21, a plurality of hollow membrane 22 and a plurality of keycap 23.Keyboard body 2 inside are provided with circuit board 21, distance on the circuit board 21 is provided with a plurality of films 22, the side of arbitrary film 22 is provided with a plurality of buffer part 221, and the top of arbitrary film 22 is provided with a keycap 23, the bottom surface of keycap 23 is provided with an extension 231 that extends downwards, to compress film 22 downwards, make the end face and circuit board 21 conductings of film 22.

During enforcement, this buffer part 221 is the cross sections of cutting in film 22 sides, this cross sections has a width on film 22 sides, destroy by cutting out the part-structure of this cross sections film 22, make film 22 in the width range of this cross sections, follow the string, then unaffected in the structure part of not being damaged, thus when allowing keycap 23 allow the edgewise bend distortion of film 22 pressing down, reduce the strength (as Fig. 4, shown in Figure 5) of keycap 23 resiliences.

In other embodiments, this buffer part 221 also can be respectively the otch or the polygonal opening of く font as Fig. 6, shown in Figure 7, can be destroyed by the part-structure to film 22 equally, to reduce the strength that keycap 23 presses down the back resilience.

During enforcement, this buffer part 221 equally spaced is located on the side of film 22, thus, can allow the strength of keycap 23 resiliences be evenly distributed on the same surface level of side, producing the bracing force that even distribution makes progress, and the direction skew when not causing keycap 23 to press down.

Therefore, the utlity model has following advantage:

Required application of force when 1, the utility model can reduce the user and knocks keyboard, and then alleviate and continue to use issuable finger burden, to avoid causing the hand injury.

2, the utility model can provide than comfort feel, and allows the user can import different keyboard instructions neatly.

In sum, according to the content that is above disclosed, the utility model really can reach the intended purposes of utility model, has practical value, so propose novel patented claim in accordance with the law.

The above is specific embodiment of the utility model and the technological means used, can derive according to the exposure of this paper or instruction and to derive many changes and correction, if the equivalence of doing according to conception of the present utility model changes, when the effect that it produced does not exceed instructions and the graphic connotation of containing yet, all should be considered as within technology category of the present utility model, closing first Chen Ming.
