  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view showing a configuration of a foldable mobile phone according to an embodiment of the present invention. In FIG. 1, the foldable mobile phone includes a first housing and a second housing having a cover, an appearance component of a case, an upper substrate on which electrical components are mounted, and a hinge portion.

  In this case, the side provided with the receiving unit (not shown) and the display unit (not shown) is the first casing, and the side provided with the transmitting unit (not shown) and the key operation unit (not shown) is the first. 2 can be used.

  The first casing and the second casing are coupled to each other by a hinge and are configured to be foldable by rotating relative to each other about the hinge.

  In FIG. 1, the first housing includes an upper case 12 having a window 11 for a display unit (not shown), an upper substrate 13 made of a PCB (Printing Circuit Board) on which electrical components (not shown) are mounted, The upper hinge frame 14 and the upper cover 15 on which these components are mounted are configured. The external part that the user can see as a mobile phone is the upper case 12. Although not shown, the upper hinge frame 14 may be configured by being incorporated into the upper case 12 by insert molding. Further, the upper hinge frame 14 may be fixed to the upper cover 15 by means such as screwing or claw fitting.

  Further, in FIG. 1, the second housing is composed of a lower cover 22 in which a key hole 21 for providing a key operation part (not shown) is opened, and a PCB (Printing Circuit Board) on which electric parts (not shown) are mounted. A lower substrate 23, a lower hinge frame 24, a lower case 25 on which these components are mounted, and the like. The external part that the user can see as a mobile phone is the lower cover 22. Although not shown, the lower hinge frame 24 may be configured by being incorporated into the lower cover 22 by insert molding. Further, the lower hinge frame 24 may be fixed to the lower case 25 by means such as screwing or claw fitting.

  In FIG. 1, a shaft 31 for connecting the upper hinge frame 14 and the lower hinge frame 24, E-type retaining rings 32 and 33, and a hinge 34 are provided as hinges, and the upper substrate and the lower substrate are electrically connected. A flexible substrate 35 connected to is shown.

  FIG. 2 shows an example in which the hinge frame of FIG. 1 is integrated with a chassis for holding a substrate, unlike the hinge frame of FIG. That is, in FIG. 2, a hinge portion 42 integrated with the upper chassis 43 and a hinge portion 42 integrated with the lower chassis 44 are shown. The upper chassis 43 is located between the upper case 12 and the upper substrate 13 in FIG. The lower chassis 44 is inserted between the lower cover 22 and the lower substrate 23 in FIG. 1, whereby the strength of the external parts can be further increased. Further, the upper chassis 43 and the lower chassis 44 have a function of an electromagnetic wave absorber (shield) that absorbs unnecessary electromagnetic waves.

  FIG. 3 shows an example in which light leakage ribs 51 are provided in a configuration in which the hinge frame is integrated with the chassis holding the substrate, as in FIG. In addition, since light leakage occurs in the split part of the case cover when the foldable mobile phone is folded (not shown), that is, by providing the rib 51 only where there is a gap between the inlays, Light leakage from the external component fitting portion can be prevented.

  4 (a) and 4 (b) show a configuration in which ribs are provided around the chassis to reinforce the external parts forming the housing. That is, FIG. 4A shows a case where a U-shaped first reinforcing rib 61 is provided around the chassis 62, and FIG. 4B shows an H-shape around the chassis 64. A second reinforcing rib 63 is provided.
