Description
Technical field
The present invention relates to computer keyboard technique field, especially relate to that the low cost of a kind of nonelastic colloidal silica and scissor support, assembling are simple, feel without rocking, and firmly, can waterproof, the ultrathin computer keyboard of dust protection.
Background technology
Along with the development of information industry, the increasingly extensive use of computing machine no matter be that notebook computer or desktop computer all be unable to do without computer keyboard, but there are some defects in traditional scissor leg structure keyboard:
1, need a large amount of man-made assembly, production efficiency is low is the problem of the most headache of current the sector;
2, structure is insecure, and keycap easily rocks, and feel is poor;
3, following keyboard is all to ultrathin future development, and traditional structure no longer adapts to;
4, traditional scissor leg structure keyboard cannot waterproof and dust, can not protection circuit part by moist;
During 5, traditional scissor foot keyboard temperature Change, the draw-in groove of keycap bottom surface and the cylinder axis of scissor support is flexible differs, easily comes off;
6, traditional scissor leg structure keyboard, extrudes because of carelessness, when clashing into or fall, keycap bottom surface draw-in groove and Holder for scissors cylinder axis easily separated;
Therefore, in view of the above-mentioned problems and shortcoming, inventor relies on the design experiences of the sector for many years, proposes a kind of can promote quality and can be convenient to production and assembly again, the simplification structure that low cost is suitable for again newly through repeatedly repetition test.
Summary of the invention
Object of the present invention is exactly that the one provided for the deficiencies in the prior art part adopts nonelastic colloidal silica, and without scissor supporting structure, low cost, less manpower takes, ultrathin, sound construction, good hand touch and waterproof and simple structure keyboard that is dust.
For achieving the above object, technical scheme of the present invention is: the thin computer keyboard of a kind of nonelastic colloidal silica and scissor support, this computer keyboard only by button bedplate, cover the printed circuit film below button bedplate and the film supports floor combination be located at below printed circuit film forms; Described button bedplate is by the rigid plastic cement integrated injection molding of high strength, button bedplate comprises the push-button unit of multiple same cross-sectional structure, this push-button unit is made up of keytop body, nonrigid connector and button base body three part, wherein, each button base body is distributed in the bottom position between adjacent two keytop bodies, nonrigid connector is connected to after between keytop body edge and button base and forms cap-shaped structure shape, and the cross section of nonrigid connector is the elastic force after slim cambered surface makes nonrigid connector stressed with arc deformation;
During work, finger presses keytop body, the stressed rear camber of nonrigid connector bends, and forming one has and outwards discharge elastic force, now keytop body moves downward vertically along with the bending of nonrigid connector, contacts connection circuit bottom keytop body with printed circuit film switching point; When finger leaves, bending nonrigid connector release elastic force, keytop body upwards sets back, and is separated bottom keytop body with printed circuit film switching point.
Bottom described keytop body, downward integrated injection molding has bossy body, and this bossy body is corresponding with printed circuit film switching point, during finger presses keytop body, and bossy body contact print circuit thin membrane switch point connection circuit.
The thickness of described keytop body is greater than the thickness of nonrigid connector.
The thickness of described button base body is more than or equal to the thickness of keytop body.
Described button bedplate is by same plastic material and an integral slab with same mold injection molding.
Described nonrigid connector is integrally closed waterproof construction.
Described nonrigid connector having several through holes makes nonrigid connector possess better elasticity.
Described film supports base plate is made up of plastic material.
Described film supports base plate is made up of metal material.
Described button bedplate is made up of high temperature resistant, cold-resistant, anti-aging, antiacid alkali, shock resistance high molecular PC or PET plastic-steel material.
After adopting said structure, the thickness of the body of keytop described in the present invention is greater than the thickness of nonrigid connector, and the thickness of described button base body is more than or equal to the thickness of keytop body; Such glue position difference in thickness object is that the glue position of its keytop body is thick, it is made to have certain steady intensity, guarantee and can not to rock during the lower press contacts of finger or recessed and affect feel, they are two years old, it is make button base support whole keyboard to have certain steady intensity that the glue position of button base is wanted thick, whole keyboard is allowed not easily to deform and the appearance of bending unequal phenomenon, they are three years old, not only the glue position thickness of button nonrigid connector part is thin, mainly allows the glue position of this part have certain support and connection intensity simultaneously but also have certain elasticity.The present invention utilizes the plastic-steel material integrated injection molding button bedplate of high strength, utilize the structure of the slim cambered surface of nonrigid connector and the intensity of high-strength plastic Steel material, make nonrigid connector at stressed rear generation arc-shaped bend, form one to have and outwards discharge elastic force, carry out elastic compression and reset, thus instead of the flexible silicon colloid of conventional keyboard and the structural design of scissor support, the present invention is made to have low cost, less manpower takes, ultrathin, sound construction, good hand touch and the feature of the simple structure of waterproof and dust.
