Soft plastic and hard sheet integrated injection-molded keyboard, keycap and production method

Abstract

The invention relates to a soft plastic and hard sheet integrated injection-molded keyboard, a keycap assembly and a production method. The keyboard is composed of an integrated keycap assembly formed by soft plastic and hard sheets, a key grid support, a printed circuit film under the integrated keycap assembly, and a keyboard bottom plate which supports the printed circuit film from below; the integrated keycap assembly formed by soft plastic and hard sheets are composed of a plurality of adjacent soft plastic key surfaces, hard sheets bonded to the soft plastic key surfaces, a soft plastic base, soft plastic supporting bodies which are connected between the soft plastic base and the soft plastic key surfaces, and soft plastic protruding elastic switching bodies which extend downwards from the soft plastic key surfaces to passes through via holes of the hard sheets and are integrally connected with the bottom surfaces of the soft plastic key surfaces. According to the production method, the production equipment includes an injection machine, a male mold and a female mold; the keycap assembly is obtained by performing integrated injection molding on soft plastic and hard plastic sheets. The keyboard and the keycap assembly of the invention have the advantages of low cost, simple assembling, waterproof and dustproof performance and excellent press deformation recovery performance.

Description

technical field [0001] The invention relates to the technical field of computer keyboards, in particular to a keyboard, a keycap and a production method in which soft rubber and a hard sheet are integrally injection-molded. 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 more troublesome to assemble and difficult to achieve waterproof and dustproof. effect, moreover, it is difficult to make the keyboard thinner and thinner by installing the single keycap one by one.
