The present invention relates to a foldable mobile device in which a case of a display part and a case of an operation part are connected via a hinge part.
In the market for mobile devices of recent years typified by mobile phones and the like, foldable mobile devices in which the cases of a display part and the cases of an operation part are connected via hinge parts have become a main stream, and foldable mobile devices which are miniaturized and reduced in thickness are in high demand.
However, the above described related art has the following problem.
FIG. 1 is a perspective view showing a closed state in a foldable mobile phone of an exemplary embodiment;
Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, the present invention is applied to a foldable mobile phone as an example of foldable mobile devices, and for example, information processing devices such as a PDA (Personal Data Assistant) and a notebook type personal computer are naturally included as examples of foldable mobile devices. Common parts in the respective drawings are assigned with the same reference numerals and characters.
As shown in FIGS. 1 and 2, foldable mobile phone 12 is configured by including, for the case of a display part, rear cover 1 of a display part especially including many design elements and including sub display part 7, and front case 2 of the display part including main display part 8 and hinge part 2c, and for the case of an operation part, rear cover 4 of the operation part including especially fewer design elements, and front case 3 of the operation part including key operation part 10 and hinge part 3c, as main components.
As shown in FIGS. 3 to 5, front case 2 of the display part and front case 3 of the operation part are configured by sheet metal parts 2a and 3a for the purpose of reducing thickness and obtaining reliable mechanical strength, and by resin parts 2b and 3b for the purpose of forming parts that have complicated shape and that are to be fitted, hinge parts 2c and 3c and the like to be fitted to rear cover 1 of the display part and rear cover 4 of the operation part. Front case 2 of the display part and front case 3 of the operation part are connected via hinge 5.
Therefore, in front case 2 of the display part, a metal material that has both sufficient mechanical strength and thickness is used as the material of sheet metal part 2a holding main display part 8. Meanwhile, in front case 2 of the display part, a resin material which allows complicated shapes to be easily molded and size adjustment to be easily made, is used as the material of resin part 2b that forms a fitting part and hinge part 2c to which the hinge is mounted. Specifically, a composite material formed of combination of a metal material and a resin material used as the material of front case 2 of the display part.
Front case 3 of the operation part is a component that whose mechanical strength is such that foldable mobile phone 12 is not broken when there is a need to press the operation keys—this is because key operation part 10, that occupies most of front case 3 of the operation part, is disposed in it as shown in FIG. 2. Front case 3 of the operation part is also a component which requires that complicated shapes be fitted to rear cover 4 of the operation part, a hinge part to which hinge 5 is mounted and the like be mounted on the front case 3.
Therefore, in front case 3 of the operation part, a metal material has both sufficient mechanical strength and thinness is used as the material for sheet metal part 3a holding key operation part 10. Meanwhile, in front case 3 of the operation part, a resin material, which allows complicated shapes to be easily molded and size adjustment to be easily made, is used as the material of resin part 3b that forms a fitting part and hinge part 3c to which the hinge is mounted. Specifically, a composite material formed of combination of a metal material and a resin material is used as the material of front case 3 of the operation part.
As shown in FIG. 2, the hinge part is configured by hinge part 2c of front case 2 of the display part made of a resin material, on which main display part 8 occupying most part of front case 2 of the display part is placed, and hinge part 3c of front case 3 of the operation part made of a resin material, in which key operation part 10 occupying most of front case 3 of the operation part is placed.
As shown in FIGS. 4 and 5, the thickness of sheet metal part 2a of front case 2 of the display part, sheet metal part 3a of front case 3 of the operation part and rear cover 4 of the operation part, which are made of a metal material, is reduced small, and thereby, the thickness of foldable mobile phone 12 can be reduced. Further, due to the structure surrounded by the metal material of sheet metal part 2a of front case 2 of the display part, sheet metal part 3a of front case 3 of the operation part and rear cover 4 of the operation part, sufficient mechanical strength of foldable mobile phone 12 can be secured, and board 9 disposed inside the case of the display part, and board 11 disposed inside the case of the operation part are protected.
As shown in FIGS. 2 and 4, antenna 6 is placed at a position covered with a resin material that is used in rear cover 1 of the display part and resin part 2b of front case 2 of the display part, and sheet plate part 2a of front case 2 of the display part, which interferes with the characteristics of the antenna, is configured to be disposed at a certain distance from the antenna 6.
Further, according to foldable mobile phone 12, the antenna part is disposed in the portion that is comprised of rear cover 1 of the display part that is made only of a resin material and of resin part 2b of front case 2 of the display part that is made of a resin material, whereby even when the antenna part is mounted in the device of the foldable mobile phone, the antenna is not shielded with the metal material, and degradation of the antenna characteristics can be avoided.
