Description

The waterproff keyboard structure of notebook computer

The utility model system is about a kind of waterproff keyboard structure of notebook computer, is meant especially a kind ofly to have waterproof and enter keyboard structure in the body.

The keyboard structure of the most notebook computer 9 in using now, as Fig. 5 and shown in Figure 6, the keycap 7 and the shearing frame 6 of outermost place end face is indispensable element, the intersection activity of utilization shearing frame 6, make the elasticity that is arranged in keycap is touched resilience after body 4 moves effect, fixed sturcture 81 places that but all at present designs all make the lower end of shearing frame 6 be fixed on the base plate is offered, so must offer corresponding hole 27 at film circuit board 2 accordingly, allow shearing frame 6 in the process that moves, can not exert an influence to film circuit board 2, relatively, film circuit board 2 itself can't waterproof problem produced, because each button is provided with a shearing frame 6 accordingly, be convenient to produce on the film circuit board 2 of three-layer type four hole 27, the linear element that colludes that four fixed sturctures 81 are more also arranged on base plate 8, thus, when if water sprinkles in people's keyboard by the top mistake of keycap, because glassware for drinking water has the characteristic of seeing that seam promptly flows, because the structure of keyboard, all connect from top to bottom, at this moment meaning is outstanding, the computor-keyboard of this notes type can be prepared to have scrapped, because the water of a cuvette is enough to form ponding in many positions, and need a very long time just can disappear, but, usually accident all is the action of drinking water that occurs in the keyboard use, at this moment power supply is conducting, probably in moment of water-sprinkling, promptly produce many not right conducting effects, many jointly positions are short-circuited, possible some zone has lost function at this point, must spend a rehabilitation expense and wait for the time of special messenger's reparation, like this, cause great inconvenience for many information users of service, because the imformation age, still need carefully use these information products, if can in design with on making some improvement be arranged, perhaps can head it off, so many spaces for exploitation are still arranged on the waterproof construction of keyboard, for the article of more realistic demand are provided, the inventor researches and develops, to solve known waterproof problem.And study not changing under the outfit prerequisite of primary structure, the technical solution of the utility model has been arranged finally.

The utility model purpose is to provide a kind of waterproff keyboard structure of notebook computer, tie up under the situation of the thickness that does not change related elements, to the fixing position of shearing frame, done breakthrough conversion, keep original result of use, but whole waterproof effect, hundred-percent improvement is but arranged, because the structure on upper strata is subject to the shearing frame, and can't improve effectively, but after the position of film circuit board is moved down, form the shearing frame and need not to pass film circuit board, just can be with the border seal of film circuit board group, itself form the structure of a waterproof, can will get rid of fully, it can't be permeated and mistake from the moisture content in the external world, just can not cause the injury of short circuit, and in the frame plate of circuit board top, elasticity is touched body, shearing frame and keycap are all irrelevant with the transmission of signal, are some mechanical realizations that influenced by water, and these structures all are to be used for contact generation signal, so the utility model can produce good waterproof effect.

Structure of the present utility model ties up to keyboard and partly is provided with a base plate, base plate is provided with film circuit board, film circuit board is provided with a frame plate, frame plate is provided with an elasticity and touches the body group, the portion of pressing that makes each elasticity touch body can pass the open-work of frame plate and touch circuit board conducting signal, be provided with the following stiff end of each shearing frame in addition in frame plate, each elasticity is touched body and is positioned on the shadow shield, shadow shield has perforation to allow elasticity touch the body clamping, and grooved hole passes by the shearing frame on the shadow shield, and the last stiff end of each shearing frame is joined with corresponding keycap respectively.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Fig. 2 is the 1a stereo amplification figure partly of Fig. 1.

Fig. 3 is the cut-open view of single key of the present utility model.

Fig. 4 is the cut-open view in the single key action of the present utility model.

Fig. 5 is the stereographic map that is used in combination of the present utility model.

Fig. 6 is the cut-open view of single key commonly used.

Fig. 7 is the three-dimensional exploded view of keyboard commonly used.

Consult Fig. 1 to shown in Figure 5, the utility model is a kind of waterproff keyboard structure of notebook computer, tie up to keyboard and partly be provided with a base plate 1, several layers film circuit board 2 is arranged on the base plate 1, it generally all is three layers

film circuit board

21,22,23, make the contact 24 of the circuit board 21 on upper strata be subjected to touch crooked, and the hole 25 of the middle layer circuit board 22 that process is isolated, contact and the conducting signal with the contact 26 of lower circuit plate 23, one frame plate 3 is arranged on this film circuit board 2, there is an elasticity to touch body group 4 on the frame plate 3, system touches the body piece by one one elasticity and is become, the elasticity that also can be the continuous pattern of a kind of sheet is touched body, the portion that presses 41 that makes elasticity touch body 4 can pass the open-work 31 of frame plate 3 and touch film circuit board 2 conducting signals, other puts frame plate 3 and is provided with 6 groups on each shearing frame that corresponding each elasticity is touched body 4, frame plate 3 is provided with the following stiff end 32 that articulates each shearing frame 6 lower end, making each elasticity touch body 4 is positioned on the shadow shield 5, shadow shield 5 has perforation 51 to allow elasticity shake-up body 4 connect and fix, and grooved hole 52 allows shearing frame 6 pass on the shadow shield 5, make each shearing frame 6 upper end be articulated in last stiff end 71 places of 7 groups of keycaps, each conductive rubber 4 joins with corresponding keycap 7 respectively, can finish the location and light is penetrated in the keyboard via shadow shield 5, and promptly there is not a position of perforation in frame plate 3 belows, allow film circuit board 2 have fluid-tight surface, make keyboard form fluid-tight device, wherein can make the periphery 20 utilization high frequency sealing-ins of each thin moding circuit plate 2, more form the waterproof construction of a sealing.

Structure in sum, the conversion of the utility model deployed position, making former is the base plate location change of commonly using in the bottom surface, but the stroke of button is all less than changing, the length of the portion of pressing 41 only need extend, promptly produce the effect of contact, so form the structure that the shearing frame need not to pass film circuit board, more can be with the border seal of film circuit board group, itself form the structure of a waterproof, can it can't be permeated and mistake from the moisture content in the external world side of foreclosing fully, just can not cause the injury of short circuit to circuit, because the frame plate of circuit board top, elasticity is touched body, shearing frame and keycap are all irrelevant with the transmission of signal, are the mechanical realizations that some water proofing property Gao Buhui are influenced by water, and these structures all are to be used for contact generation signal, so change of the present utility model just can produce good waterproof effect; Good usability can be provided, be one fully with known different structure.

The above is the detailed description of preferred embodiment of the present utility model and graphic, is not to be used for limiting the utility model, and the embodiment and the approximate construction of the spirit variation similar with it of several claims all should be contained within the protection domain of the present utility model.
