A method of fabricating a mobile computer metal shell is provided that includes the step of punching or forging a metal sheet to form a shell. Then, the step of milling and drilling is performed to form a shaped shell. Fitting members are next fixedly secured to the shaped shell at locations corresponding to the computer parts to be held, by means of adhesive bonding or welding. After the installation of the positioning members in the shaped shell, a plastic cover sheet is applied on the shaped shell.

The present invention relates to a combination mobile computer metal shell and its fabrication method especially relates to a rectangular box type metal shell thereof. According to the fabrication method of the invention, a metal sheet member is selected and processed into the desired shape, and then different fitting members are respectively fastened to the shaped metal sheet member, and then a plastic cover is covered on the shaped metal sheet member.
Regular box type mobile computer shells are commonly injection-molded from plastics. Because a mobile computer shell must have fitting means for holding computer parts, it is difficult to form fitting means in different strength on the shell during the process of injection molding. Further, a plastic mobile computer shell has less strength against impact, and low heat dissipation and electromagnetic interference protection power.
A tendency of the development for a rectangular box type mobile computer is the increasing of the size from 6″ or 8″ to 12″ even 14″ for function improving, in which a problem of the weight of the metal shell will be a most essential consideration therefor.
FIG. 1 is a mobile computer shell fabrication flow chart according to the present invention.
FIG. 2 illustrates a mobile computer shell constructed according to the present invention.
FIG. 3 shows the mobile computer shell of FIG. 2 opened.
Referring to FIG. 1, a mobile computer shell fabrication method according to the present invention comprises the steps of:
(1) selecting a metal sheet member, for example, magnesium or aluminum alloy sheet member with a proper thickness from 1.0 to 2.0 mm according to the size of the shell designed for making a box type mobile computer shell;
(2) punching or forging the selected metal sheet to the form of a shell, and stamping the positional marks for different fitting members on the inner surface of the shell simultaneously.
