Portable computer and its optical disk drive

The present invention relates to an optical disk drive, and more particularly to an optical disk drive which is applied to a portable computer and which enhances the rigidity of the upper cover.

Todayadays, most portable computers are designed to be light and thin and small in size, so as to highlight their portable characteristics, but the available internal space is relatively reduced, so how to limit the internal space of the portable computer Properly configuring each component is an important issue.

For example, a portable computer with a built-in optical disk drive conforms to the current G-base standard, and the structure of the optical disk drive itself has a certain specification. However, the upper cover of the optical disk drive is too thin, resulting in the upper cover being closer to the center of the optical disk drive. The more fragile the part, once it is subjected to too much external force to squeeze or hit, it is easy to cause the drive shaft of the optical disc to be damaged and cannot be used any more. Since the optical disk drive is generally disposed under the keyboard module when configuring the internal components of the portable computer, a certain space must be reserved between the optical disk drive and the keyboard module to prevent the user from operating the keyboard module. The force is too large to damage the CD player, but it also increases the thickness of the body of the portable computer. Therefore, how to improve the CD player itself to improve the strength of the CD player and help reduce the thickness and cost of the portable computer is a subject worthy of study.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide an optical disk drive that is applied to a portable electronic device and that enhances the rigidity of the upper cover.

To achieve the above objective, the optical disk drive of the present invention is disposed inside a portable computer. The optical disk drive comprises a body and an upper cover, and the body comprises a rotating shaft device. The upper cover is combined with the body, and the upper cover forms a convex structure and a concave structure on the surface thereof by a molding process, and the height of the convex structure is greater than the height of the concave structure to form a surface having a height difference, wherein the convex structure is raised by the concave structure The structural section is separated from a central convex portion, and the position of the central convex portion corresponds to the position of the rotating shaft device. The rigidity of the upper cover is increased by the convex structure to improve the protection effect of the upper cover on the body when the force is applied.

The portable computer of the present invention comprises a first screen, a body, an input device and an optical disk drive as described above. The body includes a support plate, and the optical disk drive is coupled to the body, and the upper cover of the optical disk drive is substantially in the same plane as the support plate. The input device can be a keyboard device or a second screen with a touch input function. The input device is coupled to the body and carries the input device through the optical disk drive and the support plate to omit the reserved space between the optical disk drive and the input device. When the optical disk drive carries the input device, the rigidity of the upper cover is increased by the convex structure, so as to improve the protection effect of the upper cover on the body when the force is applied, and reduce the overall thickness of the portable computer.
