Battery case for mobile devices

摘要

A battery pack is provided for a mobile communication device, comprising a casing defining a cavity that conforms, at least partially, to the outer shape of the mobile communication device and one or more rechargeable power cells housed within the thickness of the casing. An internal interface engages a corresponding interface on the mobile communication device to provide power from the one or more rechargeable cells to the mobile communication device. An external interface is electrically coupled to the internal interface in order to transmit signals from the mobile communication device to an external device and may further serve to recharge the one or more rechargeable power cells. The battery pack may also serve as an extendible platform by providing additional integrated communication interfaces and/or processors that can be utilized by the mobile communication device to extend its communication and/or processing capabilities.

主权项

1. A case for a mobile device comprising:
a bottom section comprising:
a back wall upon which at least a portion of a back of a housing of the mobile device will be placed against, wherein the back wall comprises a top edge;a battery cell, enclosed in the bottom section;electronic circuitry, coupled to the battery cell;a bottom sidewall, connected to the back wall at an end opposite of the top edge, that will be positioned against at least a portion of a bottom side edge of the mobile device;an internal interface, on the bottom sidewall, positioned to connect to an interface on the mobile device, and coupled through the electronic circuitry to the battery cell; andan external interface, positioned on an outside of the bottom section, coupled through the electronic circuitry to the battery cell and internal interface; and a top section comprising:
a top side that will be positioned against at least a portion of a top side edge of the mobile device when the top section is seated against the bottom section; andan open side end, opposite of the top side,wherein the top section slides onto the bottom section through the open side end, wherein when the top section is seated against the bottom section, the top and bottom sections meet at and form a seam, which extends across a back of the case, and when the top section is seated against the bottom section, a first open-polygon-shaped opening for the bottom section merges with a second open-polygon-shaped opening for the top section to form a front opening of the case through which a screen of the mobile device will be visible, the front opening having a closed shape.
