Please refer to fig. 1 and fig. 2. Fig. 1 is a perspective view of a housing of an electronic device according to a first embodiment of the disclosure. FIG. 2 is a schematic partial cross-sectional view taken along section line 2-2 of FIG. 1.

In this embodiment. The electronic device case 1 is, for example, a screen case of a notebook computer. The electronic device housing 1 includes a housing 10, an identification member 20, a fixing member 30 and a filler 40.

The casing 10 is made of magnesium aluminum alloy, for example, and is formed by die casting or computer numerical control machining. The housing 10 has an outer surface 11, an inner surface 12, a plurality of holes 13, a recess 14 and a plurality of antenna-avoiding holes 15. The outer surface 11 opposes the inner surface 12. One end of each hollow hole 13 penetrates the outer surface 11, and the other end penetrates the inner surface 12 through the relief groove 14. The antenna clearance holes 15 extend through the inner surface 12 and the outer surface 11 of the housing 10. The antenna clearance holes 15 are used to correspond to the positions of antennas (not shown) disposed on the electronic device housing 1.

The material of the marker 20 is, for example, aluminum ingot, and is formed by die casting or Computer Numerical Control (CNC) machining, for example. The label 20 includes a base 21 and a plurality of protrusions 22. The protrusions 22 all protrude from the same surface 211 of the base 21. The base 21 is located in the relief groove 14 of the casing 10 and the surface 212 of the base 21 facing away from the projections 22 is for example coplanar with the inner surface 12 of the casing 10. The protrusions 22 are respectively located in the through holes 13 and exposed from the outer surface 11 of the casing 10.

The fixing member 30 is filled in the antenna avoiding holes 15 by plastic insert-injection, and is formed on the inner surface 12 of the casing 10 and the surface 212 of the base 21, so as to fix the base 21 and the protrusions 22 of the identification member 20 in the avoiding grooves 14 and the hollow holes 13, respectively.

The filling 40 is, for example, a patch paint. The filling 40 is sprayed on the outer surface 11 of the casing 10, and the gaps G between the protrusions 22 of the identification member 20 and the casing 10 are filled in the hollow holes 13.

Next, a manufacturing process of the electronic apparatus casing 1 will be described below. Please refer to fig. 3 to 6. Fig. 3 to 6 are schematic diagrams illustrating a manufacturing process of the electronic device housing.

First, as shown in fig. 3, the case member 10 is formed by die casting or computer numerical control machining. The casing 10 is made of, for example, magnesium-aluminum alloy, and the casing 10 has a plurality of hollow holes 13, an avoiding groove 14, and a plurality of antenna avoiding holes 15 as described above.

Next, as shown in fig. 4, the marking member 20 is formed by die casting or computer numerical control machining. The material of the marker 20 is, for example, aluminum ingot, and the marker 20 includes a base 21 and a plurality of protrusions 22 as described above. Then, the protrusions 22 of the marker 20 are respectively placed in the hollow holes 13, and the base 21 is placed in the relief groove 14. At this time, the protrusions 22 protrude from the outer surface 11 of the housing member 10.

Next, as shown in fig. 5, the fixing member 30 is filled in the antenna clearance holes 15 of the casing 10 by plastic insert-injection, and is formed on the inner surface 12 of the casing 10 and the surface 212 of the base 21 of the identification member 20 opposite to the protruding portions 22, so as to fix the identification member 20.

Next, as shown in fig. 6, the filling 40 is sprayed on the outer surface 11 of the casing 10, and the gap G between the protrusion 22 of the identification component 20 and the casing 10 is filled in each of the hollow holes 13, so as to enhance the aesthetic property of the appearance of the electronic device housing 1.

In this embodiment, the housing 10 is made of magnesium aluminum alloy and the marker 20 is made of aluminum ingot, so that the manufacturing tolerance of the housing 10 and the marker 20 can be reduced, and the size of the hollow hole 13 can be matched with the protruding portion 22 of the marker 20 as much as possible, thereby reducing the gap G between the protruding portion 22 of the marker 20 and the housing 10 in each hollow hole 13. In addition, the casing 10 is made of magnesium-aluminum alloy, so that the weight of the electronic device casing 1 can be reduced. However, the materials of the housing 10 and the label 20 are not intended to limit the present invention. In other embodiments, the housing member and the identification member may be made of other suitable metal materials.

After the fixing member 30 fixes the marker 20 to the case member 10, the filler is not limited to be sprayed on the case member. In other embodiments, when the gap between the protrusion of the identification member in each hollow hole and the casing is too small to be identified by naked eyes, the casing is not required to be coated with the filling material.

Next, as shown in fig. 6, the protruding portion 22 of the marker 20 is milled flat, and the portion of the protruding portion 22 of the marker 20 and the portion of the filler 40 thereon are removed to expose the surface 221 of the protruding portion 22, and the marker 20 is milled to the original color of the aluminum ingot. Then, the marking member 20 is anodized to produce a metallic highlight effect on the marking member 20. However, after the milling process is performed on the convex portion 22 of the marker 20, it is not limited to anodizing the marker. In other embodiments, the marker may be subjected to laser engraving, metal embossing, or other processing steps after the projections of the marker are milled flat. In addition, milling the raised portion of the flag is also an optional step. In other embodiments, the identifier may not be milled flat.

In the present embodiment, the housing 10 has the antenna avoiding hole 15, and the material filling the antenna avoiding hole 15 is plastic, so that the signal transmission and reception of the antenna disposed at the position corresponding to the antenna avoiding hole 15 can be not shielded, and the signal transmission and reception efficiency of the antenna can be maintained. However, the housing member 10 is not limited to having the antenna escape holes 15. In other embodiments, if the electronic device housing does not have an antenna, the housing may have no antenna clearance hole.

The base 21 of the flag 20, on the other hand, is not intended to limit the present invention. In embodiments thereof, the identifier may be devoid of a base. In such a configuration, the casing may not have the relief groove, and the holes of the casing may directly penetrate through the inner surface of the casing. In addition, the number of the hollow holes is not limited to the invention. In other embodiments, the housing may have only one hollowed-out hole.

In the above embodiments, the identification member 20 is fixed to the casing member 10 via the fixing member 30, but the invention is not limited thereto. Referring to fig. 7, fig. 7 is a schematic partial cross-sectional view of a housing of an electronic device according to a second embodiment of the disclosure.

In this embodiment, the electronic device housing 1a includes a casing 10a and an identification member 20 a. The housing 10a has a plurality of hollow holes 13 a. The marker 20a is formed on the housing 10a by filling the entire hollow hole 13a with plastic by insert molding.

The manufacturing process of the electronic device case 1a is to provide a casing 10a having a plurality of holes 13a, and then fill the holes 13a with plastic by insert molding, thereby forming the identification member 20a on the casing 10 a. Next, the marker 20a may be selectively subjected to a processing treatment such as embossing for aesthetic enhancement.

In the embodiment, the number of the through holes 13a is not limited to the invention. In other embodiments, the housing may have only one hollowed-out hole.

In the present embodiment, by filling the hollow hole 13a of the entire casing 10a with plastic by insert injection to form the identification member 20a on the casing 10a, there is no gap between the identification member 20a and the casing 10a, so as to increase the aesthetic appearance of the electronic device casing 1 a.
