BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a cover structure of a mobile device, and more particularly to a cover structure of a mobile device for easy maintenance and partial replacement.

Description of the Prior Art

A current military laptop computer is usually configured with an opening cover at each opening of a body thereof to provide waterproofness and dustproofness. In the current design of such cover, two covers are connected to the same pivot, and the pivot is then locked between two adjacent openings of the body. One drawback of this design is that, when one of the covers is damaged, the entire assembly of the covers on both sides needs to be replaced, resulting in material waste. Further, each cover needs to be customized corresponding to the opening of individual models, and the current cover structure cannot be separately changed corresponding to only one side. For similar models, the possibility of changing the design of an opening on one side is much higher than that of both sides, which also limits the possibility of design.

In view of the above, on the basis of extensive development with the practice of theories, the Inventor is targeted at an object of improving the above issues with respect of the above prior art.
