Description

Light-weighted keyboard

Technical field

The utility model is the technical field that belongs to counter, refers to a kind of design that can alleviate keyboard weight especially.

Background technology

The thin keypressing structure of mobile computer mainly is that the assembling binding has a scissor or bridge formation formula supporting construction between keycap and reinforcement base plate, and this kind structure is exposed in: the Taiwan patent announcement is numbered No. 319438 " keyswitch with scissor support arm assembly " novel patent case and the Taiwan patent announcement is numbered " the sub-bond structure of keyboard " novel patent case No. 282857, though but these existing keyboard structures are light and handy, but owing to only can can't operate in the dark place in the operation of light place, so lack the effect of using in dark occasion, therefore the release of the backlight keyboard with light source arranged on the market.

Existing backlight keyboard structure substantially, on the whole as shown in Figure 4, it is to be provided with an assembling substrates 80, this assembling substrates 80 is metal sheets that punching press is made, and the position of corresponding each keycap (not shown) respectively punching out become a hollow-out parts 800, and in the two ends of each hollow-out parts 800 to perisporium be provided with in groups one fall a L shaped bearing frame 81 and a slide guide frame 82, each organizes bearing frame 81 is to have two and be symmetrical arranged, and each slide guide frame 82 also is to be provided with two and be symmetrical arranged.

Be provided with thin film circuit layer plate 83 and one deck rubber press button sheet 84 in regular turn in above-mentioned assembling substrates 80 end faces, wherein film circuit board 83 is provided with the pressure point 831 of a plurality of corresponding keycaps, by pressure point 831 conducting keying signals, and rubber press button sheet 84 corresponding each pressure point 831 extend upwardly and are provided with a key ring 841, and respectively organize L shaped bearing frame 81 and slide guide frame 82 is to pass film circuit board 83 and rubber press button sheet 84 and pass outside the rubber press button sheet 84, and articulate the lower edge of a bridge formation (not shown), the upper limb of building bridge articulates the bottom of keycap, the top of the bottom of keycap and contact-key ring 841.

Be provided with a light guide plate 85, a luminophor spacer 86 and a reinforcement base plate 87 in regular turn in the bottom surface of above-mentioned assembling substrates 80, wherein light guide plate 85 is provided with a guide light reflection district 851 in the bottom, be embedded with a plurality of luminescence components 861 on the luminophor spacer 86, and reinforcement base plate 87 is metal sheets and is located at the luminophor spacer 86 times, uses the reinforcement integral intensity.

From the above, because the assembling substrates 80 of keyboard is provided with a plurality of hollow-out parts corresponding with keycap 800, therefore, hollow-out parts 800 is very intensive and influence intensity, thus need be provided with the reinforcement base plate 87 that a metal sheet is made in the bottom, with the reinforcement bulk strength.Yet this reinforcement base plate 87 causes the too heavy disappearance of keyboard weight owing to be that metal sheet is made, and when going out to carry when being imposed in mobile computer, can increase user's burden on foot.

The utility model content

In order to improve above-mentioned disappearance, fundamental purpose of the present utility model is to provide a kind of can alleviate the lightweight keyboard that carries burden.

Based on above-mentioned purpose, major technique means of the present utility model comprise an assembling substrates, one is located at the film circuit board of assembling substrates top, one is located at the glue laminated button sheet of film circuit board top, a plurality of bridge formations that are based in rubber press button sheet top and are incorporated into assembling substrates, a plurality of keycaps that are installed on the bridge formation top respectively, one is located at the reinforcement base plate of assembling substrates below, this reinforcement base plate is made with compound substance, it comprises the horizontal fibers unit and the longitudinal fiber unit of complex trace weaving, and each horizontal fibers unit and longitudinal fiber unit comprise a plurality of composite fibers respectively.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:

1. because keyboard of the present utility model is to comprise a reinforcement base plate of being made by compound substance, because compound substance has the characteristic of light weight, so can alleviate keyboard weight.

2. because the utility model can alleviate keyboard weight, go out so can make things convenient for the worker to carry.

3. because reinforcement base plate of the present utility model is to be formed by horizontal fibers unit and the braiding of longitudinal fiber unit, and each horizontal fibers unit and longitudinal fiber unit are to comprise a plurality of composite fibers respectively, so it is the deviser can change the contained fiber number in horizontal fibers unit and longitudinal fiber unit in advance, required and change the fiber number of two directions with the intensity of answering keyboard.
