Abstract

The utility model provides a key structure which comprises a layer of plastic film in the middle, key characters or other effects are printed on the back of the plastic film or in other ways, then a layer of adhesive agent is respectively applied to the both sides of the plastic film, and an elastic material layer is respectively stuck and fixedly arranged on the adhesive agent. Through the key structure provided by the utility model, the complexity of the prior key manufacture can be decreased, the traditional assembly working procedure can be eliminated, and thereby the manufacturing cost of the key is reduced; the thickness of the key can be also reduced, the thickness of the key can be below 0.5 mm through the key structure, and the requirement of the ultra-thin key can be met; the elastic material layer is arranged on the surface of the key, for example, silicone rubber, and thereby the surface of the key feels exquisite and smooth, and is not easy to be scratched. The key part can achieve the waterproof and the dustproof effects.

Description

A kind of press-key structure

Technical field

The utility model belongs to the keyboard product technical field, particularly a kind of press-key structure of keyboard.

Background technology

1. the button common structure on the keyboard links combination by the adhesive layer mode for comprising plastic sheet and silica gel sheet double-layer structure in the prior art between double-layer structure.Existing button all is split, needs through the printing on plastic sheet and the operation of cutting apart with a knife or scissors, and also button one by one will be fixed on the base plate of keyboard one by one, therefore, the existing button operation of production is many, makes complicated, and dust is advanced in the slit easily between existing button, and is non-watertight.Have, existing button is because layers of material is all thicker, so its gross thickness is thicker again.In addition, existing button sense of touch does not reach fine and smooth soft and smooth requirement, and keytop also not scratch resistance is drawn.

The utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of production process few, simple and convenient that make, can reach positive waterproof, dust protection effect, can effectively reduce button thickness, make keytop that fine and smooth soft and smooth press-key structure sense of touch, that ability scratches be arranged.

The utility model is taked following technical scheme:

The press-key structure that the utility model provides is the layer of plastic film in the middle of comprising, produce character or effect that button needs in the bottom surface of plastic film, one deck bonding agent is respectively established in both sides at this plastic film, each bonding elastomeric layer that is installed with on this bonding agent.

Described character or effect can be made by printing or by other modes.

Concrete, described elastomeric layer can be silastic-layer or other elastomeric materials.Accordingly, described bonding agent can be the printing ink that silicon rubber printing ink or other can be used for elastomeric material and film bonding.

The press-key structure that the utility model provides can reduce the complexity that existing button is made, and has reduced or remitted traditional assembly process, thereby reduces the button cost of manufacture.Can also reduce the thickness of button, this press-key structure can be so that the thickness of button below 0.5mm, be realized the ultra-thin requirement of button.At keytop for example elastomeric layer of silicone rubber kinds is set, can be so that keytop have fine and smooth soft and smooth sense of touch, keytop is difficult for scratch.Whole button part can reach waterproof, the effect of dust protection.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

The front elevation of the press-key structure button that has the utility model and provide is provided Fig. 1 a;

The profile of the press-key structure button that has the utility model and provide is provided Fig. 1 b;

The back view of the press-key structure button that has the utility model and provide is provided Fig. 1 c;

Fig. 2 is the local structure for amplifying schematic diagram of the button A part shown in Fig. 1 a-1c.

Embodiment

As Fig. 1 a, 1b, 1c and shown in Figure 2, the press-key structure that the utility model provides is the layer of plastic film layer 2 in the middle of comprising, at the back up of this plastic film layers 2 or make character or other effect layers 4 of button by other modes, finish the both sides of the film after the effect and respectively establish one deck bonding agent again, each bonding elastomeric layer that is installed with on this bonding agent, wherein on the following bottom side of plastic film, be provided with silastic-layer 1, on bottom side on the plastic film, be provided with silastic-layer 3.

The concrete making step of this press-key structure can be:

At first be the selection of plastic film: plastic film thickness can be for selecting to be fit to arbitrarily the thickness of moulding as required.

Then plastic film is cut,, cut into Xiao Zhang's plastic film according to mould structure.

The plastic film that cuts that liquidates again prints, and makes it produce printing effect, uses existing printing technology can print out multiple effect.Afterwards, to a kind of printing ink of combining between silicon rubber and plastic film of being used for of whole of plastic sheet two sides printing.

Then carry out the button moulding, after film printed fully, film and silicon rubber or other elastomeric materials carried out the tow sides moulding by mould.

Button profile cutting: after the button moulding, the button profile is cut.After finishing, cutting just obtained final button.

This novel button at first reaches multiple effects such as the character of Fig. 1 a or other by printing, then by reaching effect shown in profile after film and silicon rubber or other elastomeric material moulding.As shown in Figure 2, the three layer segment structures and the thickness of button can be regulated as required, and button thickness can be accomplished below the 0.5mm.

The mobile phone that can directly adorn after button is finished or other need on the equipment of button, by as in the design sketch of Fig. 1 c back side down bottom side to be provided with the circular contact of silastic-layer 1 corresponding with mainboard electroconductive elastic sheet on mobile phone or other equipment, pressing keys front correspondence position is provided with silastic-layer 3 on bottom side on the plastic film can reach good hand feeling.Because silicon rubber or other elastomers are soft fine and smooth material, can reach good sense of touch.Simultaneously, button is a monolithic construction, and is middle without any the slit, reaches dustproof, waterproof effect.Because silicon rubber or other elastomeric materials are in the silica gel front, this novel button can be accomplished the purpose that scratch resistance is drawn, and has avoided common key-press to be exposed to the most external situation of scratch easily because of film.

This novel button manufacture craft is simple, has saved the trouble that the conventional keys elastomer is assembled with plastic film.The production process of the button of Jie Shenging is more conducive to improve the yields that button is made simultaneously greatly.

Claims

1, a kind of press-key structure is characterized in that: the layer of plastic film in the middle of comprising, respectively establish one deck bonding agent in the both sides of this plastic film, each bonding elastomeric layer that is installed with on this bonding agent.
