摘要： The present invention provides a keyboard comprising a cover plate, a base plate, a metal support, and a thin layer membrane. The cover plate comprises a plurality of supporting structures with a plurality of key caps installed on top and is movable in an up-down vertical direction. The thin layer membrane installed below the cover plate comprises a plurality of switches with each switch underlying a key cap for detecting the operation of the plurality of key caps. The metal support installed under the thin layer membrane strengthens the structure of the keyboard. The base plate is installed under the metal support and comprises a plurality of protruding columns of varying heights to accommodate different metal supports of varying thickness. By supporting the metal support of a specific thickness, the protruding columns of corresponding height help to maintain the thin layer membrane at the specified height between the cover plate and the base plate.

摘要： The present invention relates a water-resistant structure for keyboard assemblies with enhanced water-resistant ability. A keyboard hood is provided with a plurality of first slant walls extending toward the keyboard base, a keyboard base is provided with a plurality of second slant wall extending toward the keyboard hood and in parallel with the first slant walls, and an elastic water-resistant sheet is provided with upward-extending slanted edges sandwiched between the first and the second slant wall so as to form a water-resistant structure when the keyboard assembly has been fabricated. The keyboard base is fastened to the keyboard hood by fastening screws passing through holes formed in the centers of bosses in the keyboard base and screwed into holes in protrusion portions formed as part of the keyboard hood. Step-shaped sections are formed near the tip ends of the protrusion portions so as to form a tight water-proof seal between the keyboard hood and the base when the tip ends are assembled into contact with the base. Plural pairs of first parallel ribs are formed on the base, and the elastic water-resistant sheet is shaped so that it can be deeply embedded into the first slots formed between each pair of the first ribs and can cover the ribs and the keyboard base when the keyboard assembly has been fabricated. A plurality of second ribs are formed on the keyboard hood, which, when the keyboard assembly is fabricated, are deeply embedded into second slots formed in the water-resistant sheet.
