Abstract: A protective shell is provided for an electronic device with a built-in antenna. The protective shell includes a plate body, a first penetrating part and an auxiliary grounding element. The first penetrating part is located on the plate body in correspondence with the built-in antenna of the electronic device. The first penetrating part is made of insulating material. The auxiliary grounding element is disposed on the plate body in correspondence with a ground wire of the built-in antenna of the electronic device.

Abstract: A hinge structure includes a shaft, a first locking member, a second locking member, a third locking member and an elastic element. The first locking member, the second locking member and the third locking member are all disposed on the shaft, wherein the first locking member, the second locking member and the third locking member rotate with the shaft as an axis. The elastic element is sleeved on the shaft, wherein a first side edge of the elastic element leans against the second locking member, and a second side edge of the elastic element leans against the third locking member to provide an elastic force between the second locking member and the third locking member, thereby maintaining or restoring a pivoting angle of the second locking member and the third locking member with respect to the axis.

Abstract: A tablet protective cover and electronic device using the same is applied for connecting the tablet to a dock for expanding the tablet. The tablet protective cover includes a bearing seat, a back cover and a hook. The bearing seat is located on a hinge of the dock. A first end of the back cover is connected to the bearing seat, so that the back cover can rotate relative to the dock. The tablet can be placed on the bearing seat and electrically connected to the dock, and the back cover covers the back of the tablet. The hook is located on a second end of the back cover away from the bearing seat for fixing the tablet on the bearing seat.

Abstract: An electronic device includes a display and a base. The display includes a first connector and a display surface and a back surface opposite to each other. The first connector is located on the back surface of the display. The base includes a second connector. When the display is assembled to the base, the second connector of the base is connected to the first connector of the display along a connecting direction. The connecting direction is perpendicular to the display surface of the display.
