  However, since the above-mentioned conventional protective case uses a plastic decorative sheet, there is a certain limit to the texture of the plastic material and the design of the decoration applied thereto. For this reason, ceramic materials such as ceramics are used for the decorative sheet, and attempts have been made to enhance the design by using its high-quality texture. Since it is a type to be fitted, there is a problem that if the smartphone is accidentally dropped, the case body is detached from the smartphone due to the impact, and the ceramic decorative plate is broken.

  The problem to be solved by the present invention is to provide a protective case for a portable electronic device that can freely select a plurality of decorative designs using a ceramic decorative plate and at the same time prevent damage to the ceramic decorative plate. is there.

  The present invention relates to a case main body that covers the surface and four side surfaces of a substantially hexahedron portable electronic device, a lid that slides into the opening to cover the back surface or the surface of the portable electronic device, and the lid or case. By providing a ceramic decorative plate provided between the main body and the back surface of the portable electronic device, the above problem is solved.

  According to the present invention, the ceramic decorative plate is provided between the lid or the case main body and the portable electronic device, and all six surfaces of the portable electronic device are covered by the lid and the case main body. Therefore, even if the portable electronic device is accidentally dropped, the protective case does not come off from the portable electronic device. As a result, it is possible to freely select a plurality of high-quality decorative designs using the ceramic decorative plate and to prevent the ceramic decorative plate from being damaged.

  In particular, if a ceramic decorative plate made of zirconium oxide to which 2 to 4 mol% of yttrium is added is used, the decorative plate can be more reliably prevented from being damaged by its high fracture toughness.

  Hereinafter, a protective case for a smartphone according to an embodiment of the present invention will be described with reference to the drawings. 1 is an exploded perspective view of the smartphone 2 and the protective case 1 seen from the back side, FIG. 2 is a perspective view of the smartphone 2 stored in the protective case 1 from the back side, and FIG. 3 is a view of only the protective case 1 seen from the back side. The surface on which the display 21 of the smartphone 2 is provided is referred to as the front side, and the surface 23 on the opposite side is referred to as the back side.

  The protective case 1 of this example includes a case body 14, a lid body 15, and a ceramic decorative plate 16. The smartphone 2 is a portable electronic device having a thin casing having a substantially hexahedron shape, a display 21 provided on substantially the entire front side, and a lid provided on the back side. The protective case 1 of this example can be applied not only to this type of smartphone 2 but also to other portable electronic devices.

  The case main body 14 of the protective case 2 of this example includes a first opening 11 corresponding to the display surface 21 on the front side of the smartphone 2 and four side surface portions 12a to 12d corresponding to the four side surfaces 22a to 22d of the smartphone 2, respectively. And a second opening 13 corresponding to the surface 23 on the back side of the smartphone 2. As shown in FIG. 5, the edge of the first opening 11 has an inner diameter smaller than the outer diameter of the smartphone 2, thereby preventing the smartphone 2 from falling out of the first opening 11. In contrast, the second opening 13 has an inner diameter larger than the inner diameter of the first opening 11, and is inserted through the second opening 13 when the smartphone 2 is stored in the case body 14. Therefore, the case main body 14 is made of a plastic material such as polycarbonate having necessary elasticity.

  The cover body 15 of the protective case 1 of the present example has a peripheral frame portion 18 and a transparent portion 17 at the center thereof, and as shown in FIG. 5, the periphery of the second opening portion 13 (strictly speaking, the side surface portion 12a, 12b, 12d), the convex portion 181 formed around the frame portion 18 is inserted from one side surface portion 12c to close the second opening portion 13. The transparent part 17 has translucency, and the decoration applied to the ceramic decorative plate 16 described later can be visually recognized from the outside. The frame portion 18 of the lid 15 is made of a plastic material such as polycarbonate, and the transparent portion 17 is made of a plastic material such as acrylic.

  The ceramic decorative plate 16 of this example is mounted between the lid 15 and the back surface 23 of the smartphone 2, and a desired decoration is applied to the surface 16 a facing the lid 15. It should be noted that different decorations may be applied to both surfaces 16a and 16b of the ceramic decorative plate 16, and a desired decoration may be selected as necessary.

  The ceramic decorative plate 16 of this example is a ceramic made of zirconium oxide ZrO2 added with 2 to 4 mol%, preferably 3 mol% of yttrium, and is called partially stabilized zirconia and has high fracture toughness. . An ordinary ceramic material is high in strength but low in toughness, so it is easily damaged when subjected to an impact. However, partially stabilized zirconia ceramics have a feature that they are not easily damaged by impact, and even when used as the protective cover 1 of the smartphone 2, there is an effect that the partially stabilized zirconia ceramic is not damaged by impact such as dropping.

  The production method of the zirconia ceramic of this example is as follows. First, an organic solvent, a binder, and a dispersant are added to a commercially available partially stabilized zirconia raw material to form a slurry. To form a thickness of 0.8 to 1.6 mm. After drying this molded body, it is punched out with a mold and fired at a temperature of 1400-1500 ° C. to produce a ceramic plate having a thickness of 0.6-1.2 mm. This plate may be used as a product as it is, but in order to obtain a high-quality decorative plate 16, for example, 0.5 to 1.0 mm, preferably 0, is obtained by double-side polishing of a plate having a thickness of 0.9 to 1.2 mm. Process to a thickness of 6 mm. Furthermore, one side 16a (or both sides 16a and 16b) is finished by mirror polishing to obtain a product. Then, on the front side 16a (or both sides 16a and 16b), in the overpainting process, painting is performed by any of handwriting, transfer paper, and inkjet printing, and this is baked at a temperature of 800 ° C. or higher. The decorative plate 16 made of zirconia ceramics of this example can be obtained through the above steps.

  In order to store the smartphone 2 in the protective case 1 of the present example configured as described above, the lid 15 of the protective case 1 is pulled out and removed as shown in FIG. 3, and the case main body 14 as shown in FIG. The display 21 of the smartphone 2 is inserted through the second opening 13 toward the back side. Thereby, the display 21 of the smart phone 2 will be exposed from the 1st opening part 11 of the case main body 14, and it can operate a touch panel. Next, the ceramic decorative plate 16 is placed on the surface 23 on the back side of the smartphone 2, and the lid 15 is inserted from the side surface portion 12 c of the case main body 14. As a result, the ceramic decorative plate 16 is sandwiched between the lid 15 and the surface 23 on the back side of the smartphone 2, and the decorated surface 16a can be visually recognized through the transparent portion 17 of the lid 15. it can.

FIG. 7 is a cross-sectional view showing the cross section taken along line VII-VII in FIG. 6 upside down. This example is different from the embodiment shown in FIGS. 1 to 5 in that the ceramic decorative plate 16 is not placed between the lid 15 and the surface 23 on the back side of the smartphone 2 but the first opening 11 of the case body 14. It is sandwiched between the back surface 23 of the smartphone 2.

  For this reason, in order to hold the display 21 side of the smartphone 2, the lid body 15 including the frame body 18 from which the transparent portion 17 is omitted is inserted into the second opening 13 of the case main body 14. In order to prevent the ceramic decorative plate 16 from falling off, the inner diameter of the first opening 11 of the case body 14 is smaller than the outer diameter of the ceramic decorative plate 16.

  As described above, according to the protective case 1 of the present example, the decorative case 16 made of ceramics such as zirconia with decoration is used, so that it is possible to provide a protective case 1 having a high-class design and rich in design. . This texture is much different from a decorative sheet made of a plastic material or a metal material, and can increase the commercial value.

  Moreover, according to the protective case 1 of this example, since the decorative plate 16 made of zirconia ceramics having extremely high fracture toughness is used, even if the smartphone 2 is dropped, it is prevented from being damaged by its own fracture toughness. Can do.

  Moreover, according to the protective case 1 of this example, since the cover 15 is inserted into the case body 14 to cover the entire six surfaces of the smartphone 2, the protective case 1 can be removed from the smartphone 2 even if the smartphone 2 is dropped. Can be prevented. Also from this point, the ceramic decorative plate 16 can be prevented from being damaged.

  Further, according to the protective case 1 of the present example, the ceramic decorative plate 16 is simply sandwiched between the lid 15 and the surface 23 on the back side of the smartphone 2 without adhering to the case body 14, the lid 15 or the smartphone 2. Since it has a structure that only needs to be done, it can be easily replaced, and there is no occurrence of problems such as adhesive residue when replacing.
