The first fastening hole 6 is a tapered through hole penetrating the outer casing main body 1, and its aperture is gradually reduced as the first fastening hole penetrates from the outer surface of the outer casing main body 1 toward the inside of the outer casing main body.

In order to manufacture the computer casing of the first embodiment of the present invention, it is first necessary to form the casing body 1 in accordance with a desired shape and specification. For example, the casing body 1 can be manufactured by press molding, casting, or other means known in the art. Then, a first coupling groove 3 is formed on the outer casing main body 1, or a first coupling groove 3 and a first fastening hole 6 are simultaneously formed. For example, the first coupling groove 3 and the first fastening hole 6 can be machined by cutting, stamping or other means known in the art. Alternatively, the outer casing main body 1 and the first coupling groove 3 and the first fastening hole 6 thereon may be integrally molded by casting.

The second coupling groove 27 is recessed from the outer surface of the outer casing main body 21 toward the inside of the outer casing main body 21, and is located Between two adjacent first coupling grooves 23. The depth of the second coupling groove 27 is preferably 1/2 to 2/3 of the thickness of the outer casing body. As shown in FIG. 5, the second coupling groove 27 is formed in a rectangular shape, but the second coupling groove 27 may be formed in any other suitable shape. During the formation of the outer casing of the notebook computer, the material forming the peripheral portion 22 is filled into the first and second coupling grooves 23 and 27, so that a stable combination of the peripheral portion and the outer casing main body can be ensured.

Further, in order to further prevent the peripheral portion 22 from being separated from the outer casing main body 21 in the laminating direction, it is preferable to form the second fastening hole 28 at a position on the outer casing main body 21 corresponding to the middle of each of the second coupling grooves 27. The second fastening hole 28 is a tapered through hole penetrating the outer casing main body 21, and its aperture is gradually reduced as the second fastening hole penetrates from the inner surface of the outer casing main body 21 toward the inside of the outer casing main body, as shown in Fig. 8.

Similar to the manner in which the first coupling groove 3 and the first fastening hole 6 are formed, the second coupling groove 27 and the second fastening hole 28 can be machined by cutting, stamping or other means known in the art. Alternatively, the outer casing main body 21 and the second coupling groove 27 and the second fastening hole 28 thereon may be integrally molded by casting.

Also, preferably, the molded outer casing main body 21 may be subjected to passivation treatment before the injection molding process to increase the corrosion resistance of the outer casing main body 21 and the adhesion to the plastic.

Further, after the outer casing main body 21 and the peripheral portion 22 are combined, the molded outer casing may be ground, surface-coated or attached to the peripheral portion 22 for assembling the outer casing to form a finished notebook casing. Further, the above-mentioned fitting member may be integrally molded with the peripheral portion 22 in the above-described injection molding process.

Since the casing of the notebook computer of the present invention has a combination of the main body of the casing and the peripheral portion, it has the advantages of high pressure resistance, strong impact resistance, high strength, and low deformation. Since the outer casing body is made of a metal material and the peripheral portion is made of plastic, the outer casing does not shield electromagnetic waves, and thus does not affect the wireless communication of the notebook computer.

Although various embodiments of the invention have been described in detail above, Further changes and modifications can be made to the invention. It should be understood that such changes and modifications are within the spirit and scope of the invention.
