Patent ID: 8801117

Claim:
An electronic device comprising: a base; two parallel mounting plates extending from the base, each of the mounting plates defining two mounting holes; and a dummy hard disk drive comprising a bottom plate, two side plates pivotably mounted to two opposite sides of the bottom plate, and two end plates pivotably mounted to two opposite ends of the bottom plate, two mounting rods extending from an outer surface of each of the side plates; wherein the side plates and the end plates are operable to rotate to be substantially perpendicular to the bottom plate to form a hollow rectangular frame, the mounting rods are inserted in the corresponding mounting holes, to mount the dummy hard disk drive between the mounting plates; wherein when the dummy hard disk drive is not being used, the side plates and the end plates are rotated relative to the bottom plate, until the side plates and the end plate are substantially coplanar with the bottom plate; and wherein when the dummy hard disk drive is used to be transformed into a rectangular frame, the side plates are rotated to be at an acute angle relative to the bottom plate, the end plates are rotated to be at an obtuse angle relative to the bottom plate, then the dummy hard disk drive is arranged between the mounting plates, the side plates are then rotated toward the corresponding mounting plates, until the mounting rods are engaged in the corresponding mounting holes and the side plates is perpendicular to the bottom plate, the end plates are rotated to be perpendicular to the bottom plate.
