Description
Technical field
The present invention relates to computer input and output equipment, relate in particular to a kind of key dust-proofing structure.
Background technology
As a kind of instrument, electronic computer is widely used among people's life, study, work and the amusement, and is essential in our life.
Keyboard as the very low the most frequently used computer entry device of a kind of cost, brings great convenience to the user, is difficult to the imagination, if there has not been keyboard, the input speed of computer will be how.
Computer keyboard commonly used is formed by panel, drain pan, button, and button is divided into some cohorts, has position, some groups of holes on the panel, position, the corresponding group hole of each cohort.Each button as the numeric keypad of the 101 keyboard rightmost sides just constitutes a cohort, and accordingly, the panel rightmost side has position, a group hole; The main key zone that alphabet key is set for another example also is a cohort, just has position, a group hole on the relevant position of panel; Directionkeys cohort, function key cohort also are the same.Yet, be not that all computers all are operated in the dust free room, have in common office, have in family, also have in public Internet bar, external environment condition varies, so, the dust accumulation brings many worries to the user on the keyboard.
With reference to figure 1, be a kind of known keyboard press button structure, comprise keycap, keyseat and elastomer on the plate in being arranged at.The same with other existing keyboard, the side of keycap has 20 °-30 ° gradient, and keycap inside is goed deep at the keyseat top.
Above-mentioned known keyboard, the arrangement mode on keyboard be, several buttons are formed a cohort, have group position, hole on the key panel, and one group of button has the gap about 0.5mm-1mm by position, group hole extending panel between the keycap of each button.
Among Fig. 1,000 expression dust go into button inside into must through the path, as shown in Figure 1, the anti-dust performance of known press-key structure is unsatisfactory, show the following aspects: the one, it is short that dust enters the path of button inside, and the 2nd, it is broad that dust enters the route of button inside, and the 3rd, entire path revolution number of times is few, air flows is relatively easy, has improved the probability that dust enters button inside.
Because flowing of button inner air and entering of dust, often cause the elastomer premature aging and carry and touch badly, often cause whole keyboard to be scrapped in advance.
Summary of the invention
The key dust-proofing structure that the objective of the invention is to overcome above-mentioned the deficiencies in the prior art part and a kind of good dustproof effect is provided.
Purpose of the present invention can be achieved through the following technical solutions:

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to figure 2, Fig. 3, Fig. 4, Fig. 5, first embodiment of the invention is a kind of key dust-proofing structure, comprises keycap 101 and keyseat 102, has the labyrinth type dustproof construction between keycap 101 and the keyseat 102.
Refer again to Fig. 2, in the present embodiment, described labyrinth type dustproof construction comprises two dustproof grooves 1011/1012 that all are circumferentially set that are arranged at keycap 101 bottoms, the first dustproof groove 1011 is sheathed on the outside of the second dustproof groove 1012, described labyrinth type dustproof construction also comprises and is arranged at described keyseat 102 tops and two sidewalls 1021/1022 that dustproof groove 1011/1012 is complementary, article two, sidewall 1021/1022 also all is circumferentially set, and the first side wall 1021 is sheathed on the outside of second sidewall 1022.
In the present embodiment, described two dustproof groove 1011/1012 horizontal direction cross sections are the setting of " returning " font, and accordingly, described two sidewalls 1021/1022 also are the setting of " returning " font; The slide-and-guide that the inwall of second sidewall 1022 and the second dustproof groove 1012 constitute between keycap 101 and the keyseat 102.
Should be appreciated that a kind of replacement scheme as present embodiment, described two dustproof groove 1011/1012 horizontal direction cross sections also can be circular, and accordingly, described two sidewalls 1021/1022 also are circular; The slide-and-guide that the inwall of second sidewall 1022 and the second dustproof groove 1012 constitute between keycap 101 and the keyseat 102.
Also be to be understood that, the described labyrinth structure of present embodiment comprises two dustproof grooves and two sidewalls, this is a kind of preferred implementation, replacement scheme as present embodiment, described dustproof groove also can be more than three or three, accordingly, described sidewall also has more than three or three, so that constitute the labyrinth.Take this, labyrinth structure of the present invention can be defined as, by two or more the sidewall of sealing, and the deep structure that is constituted to the corresponding dustproof groove.
In the present embodiment, described keycap 101 sides have tapering, on the vertical section, the angle of keycap 101 sides and vertical direction is 5 °, common press-key structure, this angle is generally 20 °-30 °, compare with the common key-press structure, its effect is: because reduced this angle, dust enters the channel narrows of button inside, reduced the probability that dust enters button inside, dust path 000 compares in specifically can seeing figures.1.and.2.
Should be appreciated that aforesaid 5 ° of angles are a preferred implementation, according to inventor's checking, the dustproof effect that the angle of 4 ° of-6 ° of scopes also can be realized.
In the present embodiment, also comprise panel 104, panel 104 has keyhole 1041, keycap 101 is corresponding one by one with keyhole 1041, described corresponding one by one, the identical and position of the quantity of digital cap 101 and keyhole 1041 is complementary, and described keyhole 1041 also has the tapering that is complementary with keycap 101, in the horizontal direction, the distance between keycap 101 sides and the keyhole 1041 is 0.2mm; Be to be understood that, 0.2mm be a kind of preferred implementation, checking according to the inventor, when being 0.1mm, 0.25mm, 0.3mm, 0.04mm, this distance also can realize dustproof effect, also should manage and strive, when each limit of keycap with corresponding keyhole inwall have different apart from the time, the dustproof effect on each limit can be estimated separately, as long as all in the 0.1mm-0.4mm scope, the effect of totally preventing dust just can guarantee the distance of each limit and corresponding keyhole inwall.The effect that panel 104 is set is: the gap of keycap 104 sides has reduced, reduced the probability that dust enters button inside, because the space in the same cohort of common key-press between each button is to be defined by the side of each adjacent keycap to form, its gap is bigger, and in the present embodiment, panel 104 provides an independently keyhole 1041 for each keycap 101, and the gap of button side can be arranged to very little, and dust is not easy to enter button inside.In the present embodiment, described button is connected in the base plate (not shown) of keyboard by middle plate 105, constitute one independently whole; Has dismountable syndeton between described panel 104 and the base plate, so that dismounting panel 104 cleans.
On the other hand, in the present embodiment, keycap 101 sides and vertical direction be 5 ° little angle, keyhole 1041 also has the tapering that is complementary with keycap, can realize again when button is pressed, it is also less that the crack changes (increase) amount between keyhole 1041 and keycap 101 sides, also constitutes to have reduced the reason that dust enters the inner probability of button.
