Tablet personal computer cover structure

Abstract

A tablet personal computer cover structure includes a foldable member to connect a cover bolster and a cover foldable board. The cover bolster includes a load board, a lower rotatable board and an upper rotatable board which are connected to be one-piece. The load board has a first pivot hole and the lower rotatable board has a second pivot hole or a linear guide portion or a curved guide portion. Male and female rotatable buckles are respectively inserted through the first pivot hole and the second pivot hole (or the linear guide portion or the curved guide portion) and engaged with each other. The upper rotatable board has an inner surface connected with a housing to accommodate a tablet personal computer. The cover bolster further has at least one transverse engaging piece disposed on an outer side thereof. The cover foldable board is composed of two stacked boards. The cover foldable board has a transverse fold line at a central portion thereof and at least one fixing member at an outer edge thereof. When the cover foldable board and the cover bolster are folded face-to-face through the foldable member, the personal computer is received in the housing and the at least one fixing member is inserted in the engaging piece to form a closed cover. When in use, the fixing member is disengaged from the engaging piece, and then the cover foldable board is folded outward. The upper and lower rotatable boards can be turned or shifted on the load board through the male and female rotatable buckles, so that the tablet personal computer received in the housing can be turned as desired. The cover foldable board is folded up reversely through the fold line, and the fixing member is inserted in the engaging piece, and the edge of the cover foldable board is against the engaging piece to form a triangular support for the user to extend his/her hand and hold the tablet personal computer. The present invention provides the user to use the tablet personal computer at any time and protects the tablet personal computer.
