Description

Computer key-board

The utility model relates to computer input device, specifically is a kind of keyboard.

Present employed international computer keyboard, be by traditional typewriter keyboard differentiation and next, key mode is to point downwards to impact, the keyboard structure of this traditional typewriter formula, be far from suitable with the The present computer technology of develop rapidly, it has had a strong impact on keystroke and input speed, and the efficient of computing machine is greatly affected, this keyboard structure and layout also are difficult to make keyboard microminiaturized more.On the other hand, the posture that people's finger is pressed keystroke under adopting and continuing is than being easier to fatigue.

The traditional abacus of China but is to adopt " dialling " formula keystroke, the labour intensity of this mode of operation is significantly less than down by impacting keyboard, and abacus what manipulate is combined method, promptly often two even a plurality of finger use simultaneously, so not only reduced the number of bead, and more meet people's physiologic habit in the operation, and traditional like this abacus is also faster than computing machine on the computing velocity of keystroke speed even addition subtraction multiplication and division, and this is confirmed by repeatedly match.And the structure of abacus can be done and obtains quite little and do not influence work efficiency.

The purpose of this utility model is to design that a kind of keystroke speed is fast, labour intensity is low and be easier to microminiaturized computer keyboard with reference to traditional abacus.

The technical solution of the utility model is: it is to be made of a plurality of keys position, keyboard frame and keyboard control circuit plate, each key position on whole keyboard is to be made of the preceding key position that can dial backward and the back key bit pattern that can dial forward, each key position by rows, the key position of adjacent lines is to be arranged in parallel.The forward and backward key position of each key position can be imported a character or numeral respectively.Key position before finger is dialled backward produces a pulsed current signal and gives keyboard control circuit, and the character or the numeral of this preceding key position representative imported in expression, and be same, when finger is dialled key position, back forward, has promptly imported the character or the numeral of this key position, back representative.Whole key position there is no the position and moves.Because each key position by rows, the key position of adjacent lines is parallel, or parallel and arrange alternately, therefore dials a certain key position is done before or dial when operating the back, can not touch the adjacent keys position.As seen, operation of the present utility model can adopt the fingering of rechoning by the abacus with the raising keystroke speed, but " bead " is own motionless.The stroke mode that dial this front and back can improve keystroke speed greatly, reduce labor intensity of operating personnel, simultaneously, structure and layout of the present utility model are easier to make the keyboard microminiaturization, reduce the shared volume in single key position, be particularly suitable for the keyboard and the multikey bit keyboard of portable computer, for example the special-purpose input in Chinese keyboard of multikey position can utilize keyboard that encode Chinese characters for computer is set more, reduces the stroke of single Chinese character input.The utility model also can be used as the keyboard of common counter.

In sum, the utlity model has that keystroke speed is fast, labour intensity is low and be easier to advantages such as microminiaturization.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Fig. 1 is the keyboard partial front elevation view of the utility model embodiment 1;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the fragmentary side cross-sectional view of single key position among Fig. 1;

Fig. 4 is the keyboard partial front elevation view of the utility model embodiment 2;

Fig. 5 is the side view of Fig. 4;

Fig. 6 is the side sectional view of single key position among Fig. 4.

Embodiment 1, in the keyboard layout figure of Fig. 1, each key position by rows, the key position of adjacent lines is parallel and arranges alternately, does not touch the adjacent key position when stirring the key position before and after guaranteeing, is convenient to operation, saves the space.Each key position is made of keycap (1) and (4), reed (2), support (3), as shown in Figure 2, the xsect of its medium-height trestle (3) is an isosceles triangle, the base of support (3) is fixed on the keyboard frame, respectively be provided with on two waists of support (3) one can descend by keycap (1) and (4).In Fig. 3, reed (2) is arranged between support (3) and the keycap (1) and with support (3) and links to each other, and has also fixed a sheet metal on the support (3), and this sheet metal and reed (2) all link by lead (10) and keyboard control circuit.Keycap (4) is identical symmetrical structure with keycap (1).When stirring keycap (1) forward, keycap (1) compressing reed (2) is downward, reed (2) is contacted with sheet metal, annexation by them and keyboard control circuit, can produce a pulse voltage, this pulse signal is by the processing of keyboard control circuit, the input that is pressed of the key position that can reflect keycap (1) representative.The situation of keycap (4) is also similar.

Embodiment 2, and is similar to the embodiment 1 of Fig. 1 in keyboard layout structure shown in Figure 4, is the structure difference of single key position.By Fig. 5 and shown in Figure 6, each key position is made of key driving lever (5), hinge (7) and piezoelectricity rubber (8), key driving lever (5) is inverse-T-shaped, below the two ends on its base, be respectively arranged with two blocks of piezoelectricity rubber (8) that are fixed on the keyboard control circuit plate (6), piezoelectricity rubber (8) is following to two contacts should be arranged, hinge (7) is arranged on the center of key driving lever (5), key driving lever (5) is a center of rotation with hinge (7), and the base of key driving lever (5) is arranged under the keyboard frame cover plate (9).Hinge (7) is by rows, and a hinge can be fixed a line unit driving lever, and to make each key driving lever be center of rotation with the hinge when being struck.In Fig. 6, when key driving lever (5) is stirred left, key driving lever (5) is that the axle center rotates counterclockwise with hinge (7), the piezoelectricity rubber (8) of the left end compressing its underpart on the base of key driving lever (5), make below the piezoelectricity rubber (8), two contactings of cloth on keyboard control circuit plate (6), produce pulse voltage.Key driving lever (5) makes two other contacting and produces pulse signal by piezoelectricity rubber (8) when stirring to the right.Certainly during practical operation, single key remains in the front and back mode of stirring and operates, but compares with embodiment 1, and the gap between each key position can be bigger, and manufacture craft is simpler.In embodiment 2, keyboard frame cover plate (9) has restricted the rotational motion of key driving lever (5) by forward and backward stirring the time, guarantees the compressing of key driving lever (5) to piezoelectricity rubber (8).Between keyboard frame cover plate (9) and key driving lever (5) base, can be filled with flexible insulator,,, and play dustproof effect with the collision of buffering key driving lever (5) with keyboard frame cover plate (9) as sponge etc.

Embodiment 3, keyboard layout is identical with embodiment 1, and the structure that is single key position is to adopt touch-key, and each key position is the cylinder with isosceles triangle xsect, its base is fixed on the keyboard frame, respectively is provided with a touch-key as preceding key position and key position, back on its two waist.The accompanying drawing form of embodiment 3 is similar to Fig. 1-Fig. 3 of embodiment 1.

The difference of above-mentioned embodiment of the present utility model mainly is the configuration aspects in single key position, and according to design philosophy of the present utility model, the key bit architecture can have multiple, but principle is identical with mode of operation.

As for number, line number, the columns of key position in the utility model, adjacent line unit position is parallel, or parallel and staggered, and this can be provided with by actual needs.
