Definitions

  • the present invention relates to a thin key structure, and particularly relates to a thin key structure having a dazzling light generating function and formed integratedly via an extrusion molding.
  • the manufacturing way of the dazzling light keypad is as follows: to form various of different stripes on a thin metal sheet so that the keypad module can be radiated via the metal sheet.
  • such way of dazzling the keypad module still has the following drawbacks:
  • the present invention provides a thin key structure for generating dazzling light.
  • the thin key structure is made of a complex material that has different materials and color, and is formed integratedly via a way of an extrusion molding. Hence, the appearance of the key structure has a multi-layer variation and has a good reliability.
  • the present invention does not need another attachment process, and can reduce the using numbers of mold and tool. In other words, the thin key structure of the present invention can be manufactured via an apparatus only. Hence, the present invention can reduce cost.
  • One aspect of the invention is a thin key structure for generating dazzling light, comprising: a thin film layer, a protective layer, a stripe layer, and a flexible layer.
  • the thin film layer has a thickness is between 0.05 ⁇ 0.4 mm.
  • the protective layer is disposed on a top side of the thin film layer.
  • the stripe layer is disposed on a bottom side of the thin film layer.
  • the flexible layer is disposed on a bottom side of the stripe layer.
  • a thin key structure for generating dazzling light comprising: a thin film layer, a plurality of projected bodies, a stripe layer, and a flexible layer.
  • the thin film layer has a thickness is between 0.05 ⁇ 0.4 mm.
  • the projected bodies are disposed on a top side of the thin film layer respectively.
  • the stripe layer is disposed on a bottom side of the thin film layer.
  • the flexible layer is disposed on a bottom side of the stripe layer.
  • Fig. 1 shows a cross-sectional, schematic view of a thin key structure for generating dazzling light according to the first embodiment of the present invention.
  • the first embodiment of the present invention provides a thin key structure for generating dazzling light, comprising: a thin film layer 10, a protective layer 20, a stripe layer 3 0, and a flexible layer 40.
  • the thin film layer 10 can be a plastic sheet or a plastic film that is made of a transparent plastic material.
  • the thin film layer 10 is a printing film layer that has a plurality of patterns, symbols, words or numerals formed thereon.
  • the thin film layer 10 has a thickness D is between 0.05 ⁇ 0.4 mm.
  • the protective layer 20 is disposed on a top side of the thin film layer 10, and the protective layer 20 can be a wear-resistant resin film or printing ink film.
  • the stripe layer 30 is disposed on a bottom side of the thin film layer 10, and the stripe layer 30 has a plurality of regular or irregular stripes formed thereon.
  • the flexible layer 40 is disposed on a bottom side of the stripe layer 30, and the flexible layer 40 can be made of a flexible rubber material or flexible plastic material.
  • Fig. 2 shows a cross-sectional, schematic view of a thin key structure for generating dazzling light according to the second embodiment of the present invention.
  • the second embodiment further comprises a metal layer 50 disposed between the stripe layer 30 and the flexible layer 40.
  • the metal the metal layer 50 can express the quality of the appearances of the key structure according to the second embodiment of the present invention.
  • Fig. 3 shows a cross-sectional, schematic view of a thin key structure for generating dazzling light according to the third embodiment of the present invention.
  • the third embodiment of the present invention provides a thin key structure for generating dazzling light, comprising: a thin film layer 10, a plurality of projected bodies 60, a protective layer 70, a stripe layer 30, and a flexible layer 40.
  • the projected bodies 60 can be a plurality of patterns, symbols, words or numerals respectively, and the projected bodies 60 are disposed on a top side of the thin film layer 10 respectively.
  • the protective layer 70 is disposed on the thin film layer 10 and the projected bodies 60, and the protective layer 70 can be a wear-resistant resin film or printing ink film.
  • the stripe layer 30 is disposed on a bottom side of the thin film layer 10, and the flexible layer 40 is disposed on a bottom side of the stripe layer 30.
  • Fig. 4 shows a cross-sectional, schematic view of a thin key structure for generating dazzling light according to the fourth embodiment of the present invention.
  • the fourth embodiment further comprises a metal layer 50 disposed between the stripe layer 30 and the flexible layer 40.
  • the metal the metal layer 50 can express the quality of the appearances of the key structure according to the fourth embodiment of the present invention.
  • the thin key structure is made of a complex material that has different materials and color, and is formed integratedly via a way of an extrusion molding. Hence, the appearance of the key structure has a multi-layer variation and has a good reliability.
  • the present invention does not need another attachment process, and can reduce the using numbers of mold and tool. In other words, the thin key structure of the present invention can be manufactured via an apparatus only. Hence, the present invention can reduce cost.
