Protection device for an electronic device

Abstract

A protection device includes a receiving portion for receiving an electronic device and a cover portion pivotally connected to one side of the receiving portion for opening or covering the receiving portion. The cover portion includes a first reinforcing member, two right angle trapezoid-shaped second reinforcing members symmetrically located at two opposite sides of the first reinforcing member, two third reinforcing members, and a fourth reinforcing member. The two third reinforcing members respectively located between the two second reinforcing members and the fourth reinforcing member. The first, second, third and fourth reinforcing members are connected flexibly to each other. When the first reinforcing member is folded relative to the fourth reinforcing member and the second reinforcing members contact the first reinforcing member, the cover portion is rotated to allow the first reinforcing member to abut against a back of the receiving portion.
