A keyboard with an "I" shape keycap integrally formed by injection molding

Abstract

The invention relates to an injection-molded one-piece keyboard with an I-shaped keycap, a mold and a production method. The keyboard comprises the one-piece I-shaped keycap, a printed circuit film and a keyboard base plate which supports the printed circuit film. Through slotting guidance of a hard sheet, a soft plastic convex flexible switch body is integrally injection-molded at the center inside the hard sheet. The soft plastic convex flexible switch body is directly molded at the center of the hard sheet. When pressing is carried out, the soft plastic convex flexible switch body is directly pressed by the hard sheet, so that the pressing accuracy is high. The technical problems of injection molding and mold stripping of a traditional structure are solved. The entire keyboard has the advantages of small key surface gap and smooth key surface. An adhesive structure is used, so that the keyboard has the advantages of less product parts, thin overall thickness, light weight, simple assembly and low cost. A positioning ring is arranged at the bottom surface of the hard sheet to improve the pressing feel and balance.

Description

technical field [0001] The invention relates to the technical field of computer keyboards, in particular to a keyboard with an "I"-shaped keycap integrally formed by injection molding. Background technique [0002] With the development of the information industry, computers are increasingly widely used. Whether it is a notebook computer or a desktop computer, it is inseparable from the computer keyboard. There are many existing keyboard components, usually including keycaps, elastic silicone switches, scissor feet, printed circuit films and This multi-part structure makes the production cost of the keyboard higher, and the corresponding elastic silicone switches and scissor feet of each keycap need to be installed one by one, which is troublesome to assemble. The installed structure makes it difficult to make the keyboard lighter and thinner. Therefore, soft and hard rubber thinner keyboards without scissor feet and separate elastic silicone switches also appear. For the re...

[0002] With the development of the information industry, computers are increasingly widely used. No matter whether it is a notebook computer or a desktop computer, a computer keyboard is inseparable. There are many existing keyboard components, usually including keycaps, elastic silicone switches, scissor feet, printed circuit films and This multi-part structure makes the production cost of the keyboard higher, and the corresponding elastic silicone switches and scissor feet of each keycap need to be installed one by one, which is troublesome to assemble. The installed structure makes it difficult to make the keyboard lighter and thinner. Therefore, soft and hard rubber thinner keyboards without scissor feet and separate elastic silicone switches also appear. For the required product, how to ensure the stability and sensitivity of pressing the product key and the ability to recover deformation, and reduce the number of components, reduce the cost and make it thinner has always been the difficulty pursued by keyboard developers; in view of this, It is a technical problem to be solved to design a keyboard with few components, low cost, simple assembly, good pressure recovery deformation performance, sensitive pressing, and convenient injection molding.
