SOFT RUBBER KEYBOARD WITH HARD SHEET BONDED TO BOTTOM PORTION THEREOF

WIPO Patent Application WO/2018/040825

A1

A soft rubber keyboard having a hard sheet bonded to a bottom portion thereof, comprising: a printed circuit thin film (20), a keyboard baseboard (30) which supports under the printed circuit thin film,as well as an integral soft rubber key cap (10) and several hard sheets (40) provided thereon with holes; the integral soft rubber key cap comprises several key units, the key unit being formed by connecting a soft rubber key surface (11), a soft rubber support (12) and a soft rubber key base (13); each key unit corresponds to a hard sheet provided thereon with holes, and a soft rubber convex elastic switch body (14) is integrally and downwardly formed on a bottom surface of the soft rubber key surface of each key unit; during assembly, the hard sheets provided thereon with holes are sleeved over the soft rubber convex elastic switch bodies by means of holes (41), and then bonded to the bottom surfaces of the soft rubber key surfaces by using glue. Such a keyboard structure can omit the use of scissor feet and independent elastic silicone switch parts, thus saving costs, and making the keyboard lighter and thinner. The process of bonding hard sheets by using glue has simple processing steps, and allows a pressing force applied on the soft rubber key surface to be even and steady.
