Abstract

The utility model discloses a keystroke structure of a keyboard, which comprises a baseplate, a keycap and an elastic body, wherein, the elastic body is clamped between the baseplate and the keycap and provided with a neck part; a bowl-shaped bracket is arranged at one end of the neck part and face towards the baseplate, and a flange is arranged at the other end and faces towards the keycap; and the size of outer peripheral edge of the flange is larger than that of the outer peripheral edge of the neck part. Therefore, the flange is clamped between the keycap and the neck part, when the keycap is stressed unevenly, the external stress can be uniformly exerted on the neck part through the flange, so as to avoid the skew or stagger of the neck part, and improve the application convenience and operation stability of the keyboard.

Description

The press-key structure of keyboard

Technical field

The utility model relates to a kind of press-key structure, relates in particular to a kind of press-key structure of keyboard.

Background technology

Along with science and technology is flourish down, computer is universalness more and more, and wherein desktop computer and the mobile computer keyboard of need arranging in pairs or groups mostly carries out operations such as character input for the user.Therefore, with regard to the use habit of present personal computer, keyboard is one of indispensable input equipment, in order to input characters, symbol or numeral.In addition, the large-sized processing equipment that consumption electronic products that daily life such as contacted or industrial quarters are used all need be provided with press-key structure as input unit, to operate above-mentioned electronic product and process equipment.

The traditional calculating keyboard; Please refer to shown in Figure 1; It mainly comprises a keycap 10, a base plate 20 and a revertant 30, and revertant 30 is sandwiched between between keycap 10 and the base plate 20, and revertant 30 has the head 301 that keycap 10 is supported on the top; And be extended with a bowl-shape leg 302 towards base plate 20 directions from head 301; And bowl-shape leg 302 inside are extended with a contact protuberance 303, and base plate 20 is provided with a contactor 201 of corresponding contact protuberance 303, and bowl-shape leg 302 lets and between contact protuberance 303 and the contactor 201 clearance space arranged.By this, compacting keycap 10 is out of shape to make revertant 30, and then contact protuberance 303 and contactor 201 are electrically connected, and then produces the push button signalling of a correspondence.

Yet under the microminiaturized trend of electronic product, press-key structure also dwindles thereupon; When the user knocked the side of keyboard, because the dimension shrinks of head 301, it was not enough and cause producing keycap 10 unbalance stress and towards the phenomenon that tilts on one side to be easy to generate support force; As shown in Figure 1; Head 301 will be crooked state, makes contact protuberance 303 also be crooked relatively, suppresses keycap 10 this moment and removes throttle circuit switch 201 to make revertant 30 distortion; Can't touch the position of contactor 201 but contact protuberance 303 but can stagger, cause the push button signalling loose contact; In addition, the long-term application of force not instantly, head 301 is easy to generate plastic deformation and is crooked, key position can't be stablized return back to horizontal, and when letting user's operation keyboard, feels very not convenient.
