Moreover, when applied to automobile interior parts, it can contribute to weight reduction of the entire automobile. 17 (c) and 17 (d) have a shallow drawing shape with a shallow rise, but may have a deep drawing shape with a larger rise.
  • the pressing portion 27 of the switch cover 26 of the present embodiment may have a protruding portion 29 (see FIG. 18).
  • the presence of the protruding portion 29 makes it easy to understand the location where the switch portion is located.
  • the protrusion 29 may have a circular cross section (see FIG. 18A). In addition to the circular shape, an oval shape, a polygonal shape, or the like can be appropriately designed.
  • the protrusion 29 has a three-dimensional shape, and this form is an example in which a part of the switch cover has a three-dimensional shape.
  • the protrusion 29 may be a plurality of protrusions formed in the area of the pressing part 27 (see FIG. 18B).
  • the protrusion 29 may be a combination of FIG. 18A and FIG. 18B (see FIG. 18C).
  • Such a switch cover 26 can be used for household appliances, such as a rice cooker and a washing machine, and a game machine, for example.
  • the electronic device back cover and the electronic device casing using the electronic device back cover according to the present invention can be widely used for two-fold type electronic devices such as personal computers, smartphones, tablets, and game machines. Further, it can be applied to a two-fold display device such as an in-vehicle display.

Abstract

La présente invention a pour objet de fournir un couvercle arrière pour un dispositif électronique qui est fortement étanche à l'eau et à la poussière et qui a une rigidité élevée, et qui est mince et léger, et un boîtier pour un dispositif électronique comprenant ledit couvercle arrière. L'invention concerne également un couvercle de commutateur pour lequel un corps de support n'est pas nécessaire, et qui a une rigidité élevée et un faible degré d'épaisseur. À cet effet, l'invention porte sur un couvercle arrière pour un dispositif électronique comprenant : une partie courbée formée dans une position dans laquelle une feuille de résine renforcée par des fibres est divisée en deux ; et deux parties rigides formées dans des régions autres que la partie courbée. L'invention concerne également un boîtier pour un dispositif électronique comprenant le couvercle arrière pour un dispositif électronique, et deux couvercles avant. Les deux couvercles avant sont formés à partir de la feuille de résine renforcée par des fibres ayant comme matériau de base une résine thermodurcissable ou une résine thermoplastique. Au moins l'un des deux couvercles avant a une forme de cadre. L'invention concerne également un couvercle de commutateur comprenant : une partie de dépression formée, parmi la feuille de résine renforcée par des fibres, dans une région recouvrant une partie de commutation ; et une partie rigide formée dans une région autre que la partie de dépression.
