Description

Keyboard

Technical field

The utility model relates to a kind of arcuate structure keyboard, particularly relates to a kind of arcuate structure keyboard that comprises shear-type key.

Background technology

Keyboard is to the computer system instrument of widespread usage the most in order to input characters/numeral or instruction.General keyboard has the different keycap of various surficial inclinations usually, so that user's operation.Along with the flourishing and scientific and technological progress of information, for the user is provided the more comfortable sense of touch of importing easily, keyboard also is designed to meet the arcuate structure of ergonomics.

Traditional arc keyboard, especially desktop PC keyboard adopt mechanical type or plug-type press-key structure usually.Plug-type button generally comprises a button base plate, the keycap with plug-in package and elastic parts.In order to cooperate the structure of keycap plug-in package, the button base plate has complicated Connection Block usually for the plug-in package that connects keycap, makes keycap can do vertical moving with respect to base plate.Yet Connection Block complicated on the base plate makes traditional arc keyboard, has increased degree of difficulty and the cost of making the base plate of bending or arc.

The base plate of general button all adopts injection molding to make.Therefore, when die sinking, must cooperate be injection molded into the Connection Block that pattern make different angles of the radian of keyboard, suitable time and effort consuming with base plate.In addition,, just must die sinking do different base plates, not only make production process complicated more, more increase cost of manufacture along with the radian difference of arc keyboard.

At the shortcoming of above-mentioned prior art, be necessary to provide a kind of arcuate structure keyboard, to simplify production process and to reduce cost of manufacture.

The utility model content

The purpose of this utility model is to provide a kind of keyboard, and it utilizes the distinctive supporting mechanism connected mode of shear-type key, forms the arc keyboard, to simplify the program of making the different angles fixed mechanism.

Another purpose of the present utility model is to provide a kind of keyboard of arcuate structure, and it utilizes the fixed mechanism of sheet metal as shear-type key, with the curved plate of Bending Processing formation simply, simplifies production process and reduces manufacturing cost.

A purpose more of the present utility model is to provide a kind of keyboard of arcuate structure, and it has the identical keycap of a plurality of surficial inclinations, to reduce manufacturing cost.

The purpose of this utility model is achieved in that promptly provides a kind of keyboard, comprising: a loam cake, this loam cake have one first curved surfaces, and this loam cake comprises one for the key area that holds a plurality of buttons; And a base plate, this base plate has one second curved surfaces to first curved surfaces that should loam cake, and this base plate has a plurality of for the Connection Blocks that connect these a plurality of buttons; Wherein, be provided with a scissor structure in each this button.

Wherein, a plurality of buttons comprise a plurality of keycaps, and a plurality of keycap has the surface at identical angle of inclination.

Base plate of the present utility model is a sheet metal, and keyboard of the present utility model also comprises a lower cover, and lower cover combines with loam cake and forms a housing, and base plate is positioned among the housing.Scissor structure of the present utility model comprises one first support arm and one second support arm, and first support arm connects this second support arm rotationally.Scissor structure comprises a junction, turns and connect movably the Connection Block of base plate.

Advantage of the present utility model is that it is designed to the arc keyboard, and has the identical keycap of a plurality of surficial inclinations, makes this keyboard structure reasonable, and manufacture craft is simple, reduces cost.

Description of drawings

Fig. 1 is the top view of the arc keyboard of the utility model first embodiment;

Fig. 2 is the cross-sectional view of Fig. 1.

Embodiment

With reference to figure 1 and Fig. 2, it is respectively the top view and the cross-sectional view of the utility model one embodiment keyboard 10.The utility model provides a kind of keyboard 10 to comprise a loam cake 12 and a base plate 14.Loam cake 12 has one first curved surfaces 122, as the curved surfaces of convex surface.The curved surfaces of this convex surface is a surface protruding upward, and its radian is shown in camber line 126.And loam cake 12 comprises a key area 124.Key area 124 is for holding a plurality of buttons 16.Each button 16 has a scissor structure 162.Base plate 14 has first curved surfaces 122 of one second curved surfaces, 142 corresponding loam cakes 12, and base plate 14 has a plurality of Connection Blocks 144 for connecting a plurality of buttons 16.

Base plate 14 of the present utility model is a sheet metal, and is arranged on the base plate 14 with predetermined gap between a plurality of Connection Block 144.Utilize easy engineering bending with metal bending, with the curved surfaces 122 of the convex surface that forms corresponding loam cake 12.Should be noted that at this, loam cake 12 of the present utility model and base plate 14 are in an embodiment, though the curved surfaces with convex surface illustrates, but those skilled in the art should know curved surfaces of the present utility model and comprise the curved surfaces (promptly downwards recessed surface) of concave surface, or the bending cambered surface done of any cooperation ergonomics (ergonomics).

In addition, base plate 14 connects the predetermined gap setting of 144 of the Connection Blocks of each button 16, and the radian that cooperates base plate 14 bendings is different and change, particularly when base plate 14 bending shapes become concave surface.That is, big more the closer to the predetermined gap between the Connection Block 144 of cambered surface center when bending shape becomes concave surface, when avoiding base plate 14 to be bent into concave surface, can cause the spacing between the button 16 too little, make and touch interference between the keycap mutually.

Scissor structure 162 of the present utility model comprises one first support arm 1620 and one second support arm 1622, and first support arm 1620 is for connecting this second support arm 1622 rotationally.Scissor structure comprises a junction 1624, and it turns and connect movably the Connection Block 144 of base plate 14.Scissor structure 162 of the present utility model is similar to general prior art, and is not emphasis of the present utility model, so do not give unnecessary details at this.

In addition, a plurality of buttons 16 of the present utility model comprise a plurality of keycaps 164, and a plurality of keycap 164 has the surface at identical angle of inclination.That is all be identical, no matter each keycap 164 is dip plane angles of size, shape or key cap surface.Therefore, keyboard 10 of the present utility model utilizes its crooked cambered surface, does not need to make the different keycap in various angles of inclination especially, can meet user's operation habit.

Keyboard 10 of the present utility model also comprises a lower cover 18.Lower cover 18 combines with loam cake 12 and forms a housing, and base plate 14 is positioned among the housing.Lower cover 18 cooperates the arcuate structure of keyboard, the curved surfaces that similarly has a correspondence.But the true form of lower cover is not limited thereto.That is, the shape of lower cover 18 to be being combined into housing with loam cake 12, and is purpose for holding base plate 14 and can stably being positioned over desktop.Moreover for emphasizing the utility model, therefore explanation of the present utility model does not comprise other member of button 16, as the elastic body of thin film switch layer and actuation switch etc., but in the practical operation, comprises other member.
