Abstract: A data-storage device mounting apparatus includes an enclosure and one or more elastic members. The enclosure includes a shell and a cover. The elastic member includes a mounting portion mounted on the cover, a deformable portion, and an engaging portion. The mounting portion is attached to a first end of the deformable portion and the engaging portion attached to a second end of the deformable portion. The first deformable portion end is opposite the second deformable portion. The shell defines an opening, a cavity, and an engaging hole. The engaging portion engages with the engaging hole when the cover is engaged with the shell to substantially cover the shell opening. The engaging portion may be disengaged from the engaging hole allowing the cover to be disengaged from the shell. The data-storage device is positioned within the cavity when the cover is engaged with the shell.

Abstract: A photovoltaic assembly includes a solar plate and a protective cover. The protective cover covers one side of the solar plate and includes a cover body. The protective cover is rotatable relative to the solar plate between a closed position and an open position. When the protective cover is in the closed position, the cover body covers the solar plate and is substantially parallel to the solar plate to prevent foreign matter from adhering to the solar plate. When the protective cover is in the open position, an angle is defined between the cover body and the solar plate so that the foreign matter slides off the cover body.

Abstract: A portable electronic device includes a front frame, a rear panel attached to a rear side of the front frame, and a side cover. The front frame includes a main body and a first mating flange extending from the main body. The rear panel includes a main plate and a first flange extending from the main plate. The first flange and the first mating flange clamp each other. A gap is defined in the first flange or the first mating flange. The side cover is attached to exteriors of the first flange and the first mating flange. A clamping portion protrudes from the side cover. The clamping portion is movable in the gap between a detachable position where the clamping portion is disengageable from the gap and a lock position where the clamping portion clamps an inside portion of the first flange or the first mating flange.

Abstract: A bracket assembly includes a bracket and a tray secured in the bracket for accommodating a disk drive. The tray includes a base panel, a pair of side panels extending from opposite sides of the base panel, a first plate extending substantially perpendicularly from an upper edge of one of the pair of side panels, and a second plate extending substantially perpendicularly from an upper edge of the other one of the pair of side panels. The first plate and the second plate are partially overlapped with each other and fixed to each other. The tray includes a pair of sidewalls abutting inner sides of the pair of side panels and a pair of connecting pieces connected between the pair of side walls for supporting the disk drive.
