Description

Press-key structure

Technical field

The utility model relates to a kind of press-key structure, refers to a kind of minimizing package program especially, and can make the smooth-going press-key structure that slides.

Background technology

Notebook computer is owing to have the function of being convenient to carry and significantly improve the document Data Processing at present, so extensively being subjected to reaching certainly of market dealer and user adopts, and general dealer is for promoting the being easy to carry about with one property of notebook computer, so research and development improvement constantly is in the hope of reducing its volume weight, and then reach frivolous purpose, the thin keypressing structure that is adopted as for present notebook computer keyboard, please refer to shown in Figure 1, it mainly is that the assembling binding has a scissors-type (or bridge formation formula) supporting construction between keycap and base plate, it comprises: a keycap, be a cap body, its oblique cap central interior of down extending is down extended a cap post; Below homonymy inwall extends the paste of two levels, and side is then down extended two hatpins in the cap top, its central tool one hook groove in addition; Extend the two cap ribs parallel corresponding to the cap inner top one of paste in addition with paste;

One builds bridge, and intersects the state that can reverse each other that links by a post frame and a tenon frame; Two parallel mast ends of post frame are circular styletable, and central authorities are each tool one post hole then, form framework by two parallel post tenons bindings between two masts, and the upper prop tenon is embedded in the hook groove; The tenon frame also is the one frame, and tenon rod end place, both sides is circular tenon end, the outwards vertical tenon axle that extends of its central authorities, tenon axle and be placed in paste and the cap intercostal on it; In addition a tenon core is respectively extended in tenon bar mediad inboard, but and embedding be through at the post hole; Tool two parallel tenon beam one link to surround framework between two tenon bars;

One bridge plate is a plate body, and it opens plate hole corresponding to the keyswitch place, and corresponding to tenon axle place, below, and it is prominent and open board slot and wear for its embedding vertically to form plate; Corresponding to following square column tenon place, it is ccontaining for it that the projection turnover forms plate hook in addition;

One key ring flat-plate for soft elastic material is made, corresponding to each cap post place, is dashed forward and is established a key ring, and its inside top surface is a salient point;

One thin film circuit is corresponding to each salient point place tool circuit junction;

One base plate is a plate body, and links that fixedly bridge plate, key ring flat-plate and thin film circuit form.

But this conventional construction has following shortcoming:

1. the part complexity increases manufacturing cost.

2. when assembling, the post frame of bridge formation and the axostylus axostyle at tenon frame two ends must be nested on the bridge plate very complicated in assembling respectively.

3. because of its board slot is open shape, so the axostylus axostyle that mast and tenon bar take place easily is by the situation that wherein comes off.

4. rectangular because of its bridge formation, the key ring flat-plate then is cylindric, so this bridge formation also can't move by the limit key ring flat-plate, and then the situation that causes the key ring flat-plate can be shifted when being subjected to pushing.

Summary of the invention

Creator of the present utility model is because the above-mentioned shortcoming of commonly using device therefore at its very crux, takes up to be sought improvement, mending it lacks, in the hope of seeking a reasonable solution, analyse, design through grinding many times, finish press-key structure of the present utility model finally.

Fundamental purpose of the present utility model provides a kind of press-key structure, and its assembling is fast and convenient, more can simplified structure, and then the saving manufacturing cost, and because of first and second key frame interlinks together, and can draw mutually and as the other side's support, and then the increase anchorage force, simultaneously, also make slip smooth-going.

A kind of press-key structure that the utility model provides, it is provided with a base plate, this base plate is provided with the cover frame that interlocks relatively and be barb type, be provided with the embedding hole in those cover frames, those embedding holes interlock and keep a determining deviation, on base plate, then be provided with a circuit board, this circuit board is provided with the elastic body of a tool electric conductivity, this elastomeric perimeter is provided with relative first, two key frames, this is first years old, two key frames, one end is respectively equipped with hinged arm, and those are first years old, the two key frame other ends then are respectively equipped with outward extending pillar, this pillar is away from first, one end of two key frames is respectively equipped with axostylus axostyle, but those axostylus axostyles difference sleeves are in the embedding hole of base plate, those pillars are then with first, two key frame joints then are provided with perforation, for this first, the hinged arm of two key frames is pegged graft mutually, and make this first, two key frames link together and form a Y word moulding, moreover those are first years old, be nested with a keycap on the two key frames.

Another purpose of the present utility model is to provide a kind of press-key structure, and set barb type cover frame is the shape of falling U, the shape of falling V or falls semicircle shape on the embedding hole of its base plate, make axostylus axostyle wear wherein after, the situation that can come off because of slippage not.

Another purpose of the present utility model is to provide a kind of press-key structure, its first and second key frame opposing end faces is arc-curved shape, not only can increase anchorage force, and can cooperate elastomeric shape, and elastic body is limited in whereabouts, reason is not pushed the situation that produces displacement.

So, when assembling, be nested on the base plate because of those only have the outward extending pillar of an end, and make that assembling is fast and convenient, more can simplified structure, and then saving manufacturing cost, and because of this first and second key frame interlinks together, and can draw mutually and, and then increase anchorage force as the other side's support, simultaneously, also make slip smooth-going.
