Abstract: An assembly structure for an electronic device protecting casing and an interfacing structure with magnetic connectors includes a protecting casing for protecting a tablet form electronic device and an interfacing device for power or signal transferring to or from the protecting casing. The protecting casing includes a casing side connector. The casing side connector includes an inner connector and an outer connector. The interfacing device includes an interfacing connector. A magnetic connecting device is used for mechanically and magnetically connecting an interfacing connector of the interfacing device with an outer connector of the protecting casing. The magnetic connecting device includes at least one interfacing side magnetic unit which is installed on the interfacing device at the same side installing the interfacing connector, and at least one casing side magnetic unit which is installed one the casing side connector at the same side having the outer connector.

Abstract: An electronic device protecting casing with heating function includes: a casing; a battery box within the casing; an interior of the battery box being arranged with a battery, a back side of the battery box being formed with an opening for receiving the battery; an outer cover serving to seal the opening; an inner side of the outer cover being formed with a heat isolation sheet; a heating unit being installed within the casing for heating the tablet computer; the heating unit including an electric heating plate. When power of the battery is transferred to the electric heating plate, the electric heating plate generates heat power and then transfers the power to the tablet computer for heating it; and a control circuit is installed within the casing; the electric heating plate is connected to the battery through a control switch; and the control circuit is connected to the control switch.

Abstract: A water and dust proof multi-functional package for receiving a tablet electronic device includes a seat; an upper cover; one side of the upper cover being pivotally connected to the seat and thus being turnable with respect to the seat; the upper cover having a transparent portion; the transparent portion being a transparent film which is adhered to the upper cover by waterproof glue; four buckles being positioned on lateral sides of the seat; each buckle containing a pivotal sheet and a buckling portion; the pivotal sheet being pivotally installed to the seat and being rotatable with respect to the seat. When the upper cover is closed, the outer side of the pivotal sheet is smooth to prevent dusts from adhering to the buckle. The buckle further comprises a waterproof adhering sheet for waterproof. Moreover, dusts are impossible to enter into the structure.

Abstract: A multifunctional stand frame for a tablet electronic device comprises a seat; a bottom of the seat serving to connect a back side of a tablet electronic device; the seat having a plurality of retaining holes; in installing, the seat being connected to the tablet electronic device by using a connecting unit to pass through the retaining hole of the seat and a locking hole of the tablet electronic device; so that the seat is installed to the tablet electronic device; a disk being positioned above an upper side of the seat and being rotatably installed to the seat; a center of the disk having a through hole; a fixing shaft extending from an upper side of the seat and penetrating through the through hole of the disk; the disk being loosely arranged to the seat through the retaining hole and being rotatable with respect to the fixing shaft.

Abstract: A clamping device for a protection casing of an electronic device serves to clamp a protection casing for receiving an electronic device. The protection casing includes an upper cover for covering an upper side of the electronic device and a lower cover for covering a lower side of the electronic device; and in assembly state, the upper cover is connected to the lower cover to enclose the electronic device. The clamping device comprises an upper clamping frame and a lower clamping frame for clamping the protection casing therein. A combining structure is arranged on lateral sides of the upper clamping frame and the lower clamping frame for combining the upper clamping frame and the lower clamping frame so that the upper clamping frame and the lower clamping frame clamp the protection casing tightly and thus the protection casing retains its function for a long time.
