Abstract
The invention relates to a computer keyboard with a nonelastic silica gel body and a scissor-kick support. The computer keyboard is formed only by combining a key base board, a printed circuit film covering the lower side of the key base board and a film support bottom board arranged under the printed circuit film; the key base board is subjected to integral molding forming by using high-strength hard plastics and comprises a plurality of key units with same cross structures, wherein each key unit consists of a key surface body, an elastic connection body and a key base body, each key base body is distributed at the bottom position between every two adjacent key surface bodies, each elastic connection body is connected between the edge of each key surface body and each key base to form a cap-shape structure, and the cross section of each elastic connection body is a thin-type cambered surface, so that each elastic connection body has elasticity with cambered deformation after being stressed. The thin-type computer keyboard has the characteristics of low cost, ultrathin-type property, firm structure, good handfeel and simple waterproof and dustproof structure; and the cost of labor is saved.
Description
Technical field
The present invention relates to the computer keyboard technique field, low cost, the assembling that especially relates to a kind of nonelastic colloidal silica and scissors foot support is simple, feel does not have and rocks, and firmly, can waterproof, and the ultrathin computer keyboard of dust protection.
Background technology
Along with the development of information industry, the increasingly extensive use of computer, no matter be that notebook computer or desktop computer all be unable to do without computer keyboard, yet there are some defectives in traditional scissors leg structure keyboard:
1, need a large amount of artificial assemblings, production efficiency is low to be the problem of the headache of current the sector;
2, structure is insecure, and keycap easily rocks, and feel is poor;
3, following keyboard all develops to ultrathin direction, and traditional structure no longer adapts to;
4, traditional scissors leg structure keyboard can't waterproof and dust, can not protective circuit partly be subjected to humidity;
5, during traditional scissors foot keyboard temperature Change, the cylinder axis of the draw-in groove of keycap bottom surface and scissors foot support is flexible to differ, and easily comes off;
6, traditional scissors leg structure keyboard, careless extruding, clash into or situation about falling under, keycap bottom surface draw-in groove and Holder for scissors cylinder axis are easily separated;
Therefore, in view of the above-mentioned problems and shortcoming, the inventor relies on the design experiences of the sector for many years, proposes a kind ofly new can promote quality and can be convenient to production and assembly again, the low-cost simplification structure that is suitable for again through repetition test repeatedly.
Summary of the invention
Purpose of the present invention is exactly the nonelastic colloidal silica of a kind of employing that provides at the deficiencies in the prior art part, no scissors foot support structure, and low cost, less manpower takes, ultrathin type, sound construction, good hand touch and waterproof and simple structure keyboard dust.
For achieving the above object, technical scheme of the present invention is: the slim computer keyboard of a kind of nonelastic colloidal silica and scissors foot support, this computer keyboard only by the button bedplate, cover the printed circuit film of button bedplate below and the film supports base plate that is located at below the printed circuit film combines; Described button bedplate is by the rigid plastic cement integrated injection molding of high strength, the button bedplate comprises the push-button unit of a plurality of same cross-sectional structures, this push-button unit is made of keytop body, nonrigid connector and button base body three parts, wherein, each button base body is distributed in the bottom position between adjacent two keytop bodies, nonrigid connector is connected back formation cap-shaped structure shape between keytop body edge and the button base, and the cross section of nonrigid connector is the elastic force that has arc deformation after slim cambered surface makes nonrigid connector stressed;
During work, finger presses keytop body, the camber bending of the stressed back of nonrigid connector, forming one has outside release elastic force, this moment, the keytop body moved downward vertically along with the bending of nonrigid connector, and keytop body bottom contacts connection circuit with the printed circuit film switching point; When finger left, crooked nonrigid connector discharged elastic force, and the keytop body upwards sets back, and separate with the printed circuit film switching point keytop body bottom.
Bossy body is arranged at described keytop body bottom integrated injection molding downwards, and this bossy body is corresponding with the printed circuit film switching point, during finger presses keytop body, and bossy body contact print circuit film switching 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 with a kind of plastic material with an integral slab of same mold injection molding.
Described nonrigid connector is integrally closed waterproof construction.
Having several through holes on the described nonrigid connector makes nonrigid connector possess better elasticity.
Described film supports base plate is made by plastic material.
Described film supports base plate is made by metal material.
Described button bedplate is made by 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 purpose is that the glue position of its keytop body is thick, make it that certain steady intensity be arranged, guarantee can not rock during press contacts down or recessed and influence feel with finger, they are two years old, it is to make the whole keyboard of button base support that certain steady intensity be arranged that the glue position of button base is wanted thick, allow whole keyboard be difficult for deforming and the appearance of crooked unequal phenomenon, they are three years old, the glue position thickness of button nonrigid connector part will approach, and mainly is to allow the glue position of this part promptly have certain support and connection intensity to have certain elasticity simultaneously again.The present invention utilizes high-intensity plastic-steel material integrated injection molding button bedplate, utilize the structure of slim cambered surface of nonrigid connector and the intensity of high-strength plastic steel, make nonrigid connector produce arc-shaped bend in stressed back, form one outside release elastic force is arranged, carry out elastic compression and reset, thereby the structural design that has replaced the flexible silicon colloid and the scissors foot support of conventional keyboard, make the present invention have low cost, less manpower takes, ultrathin, sound construction, the characteristics of the simple structure of good hand touch and waterproof and dust.
