The back cover covers the main framework and has an expansion window. The door cover covers the expansion window. The functional module is disposed on an inner side of the door cover and electrically connected to a motherboard in the main framework. An operation interface corresponding in position to an outer side of the door cover is disposed on one side of the functional module. One side and the other side of the functional module oppose each other. The stop element is disposed on the inner side of the door cover, abuts against the other side of the functional module, and thus prevents the functional module from retracting under an external force. Therefore, the mobile electronic device is insusceptible to a collision and a fall. ## Claims ### Claim 1 A mobile electronic device, comprising: a main framework having a motherboard; a back cover covering the main framework and having an expansion window; a door cover covering the expansion window, the door cover comprising a back plate and a lateral plate; a functional module disposed on an inner side of the door cover, electrically connected to the motherboard, and having a first side on which an operation interface is disposed, the operation interface facing the lateral plate; and a stop element, disposed on the inner side of the door cover, wherein the stop element comprises a first abutting portion and a connecting portion, the first abutting portion abutting against a second side of the functional module, the second side facing away from the operation interface, and the connecting portion abutting against the back plate. ### Claim 2 (depends on 1) The mobile electronic device of claim 1, wherein the lateral plate comprises an opening, the operation interface facing the opening. ### Claim 3 (depends on 2) The mobile electronic device of claim 2, further comprising a transparent material covering the opening. ### Claim 4 (depends on 1) The mobile electronic device of claim 1, wherein the functional module is a barcode reader, a fingerprint detector, a camcorder lens, or an infrared communication apparatus. ### Claim 5 (depends on 1) The mobile electronic device of claim 1, wherein the expansion window comprises an opening in a back surface and a lateral surface of the mobile electronic device. ### Claim 6 (depends on 5) The mobile electronic device of claim 5, wherein the back plate covers the opening at the back surface and the lateral plate covers the opening at the lateral surface. ### Claim 7 (depends on 1) The mobile electronic device of claim 1, wherein the back cover comprises an outer connecting surface surrounding the expansion window, the outer connecting surface comprising at least one opening. ### Claim 8 (depends on 7) The mobile electronic device of claim 7, wherein the back plate comprises at least one opening corresponding to the opening in the outer connecting surface. ### Claim 9 (depends on 8) The mobile electronic device of claim 8, wherein at least one fastener passes through the opening of the back plate and the opening of the outer connecting surface to fix the back plate on the back cover. ### Claim 10 (depends on 1) The mobile electronic device of claim 1, wherein a rib and a resilient portion are disposed on the inner side of the door cover and an outer connecting surface of the back cover, respectively, the outer connecting surface surrounding the expansion window, thereby allowing the resilient portion to be pressed by the rib and thus resiliently sag when the door cover covers the expansion window. ### Claim 11 (depends on 10) The mobile electronic device of claim 10, wherein the resilient portion is a resilient pad or a waterproof foam. ### Claim 12 (depends on 10) The mobile electronic device of claim 10, wherein the inner side of the door cover includes a back plate inner side of the back plate and a lateral plate inner side of the lateral plate, wherein the rib is protrudingly disposed on the back plate inner side and the lateral plate inner side, or the resilient portion is disposed on the back plate inner side and the lateral plate inner side. ### Claim 13 (depends on 1) The mobile electronic device of claim 1, wherein the first abutting portion further abutting against a third side of the functional module, the third side facing away from the back plate. ### Claim 14 (depends on 13) The mobile electronic device of claim 13, wherein the stop element is fixed on the inner side back plate.
