Electronic apparatus and protective cover of mobile device

摘要

An electronic apparatus and a protective cover for a mobile device are disclosed. The protective cover is removably attached on an outer surface of a mobile device. The protective cover comprises an outer protective layer, a thermo-conductive layer and a thermoelectric material layer. The thermo-conductive layer is attached on the outer surface of the mobile device. The thermoelectric material layer has a first side adjacent to the thermo-conductive layer and a second side adjacent to the outer protective layer. The thermoelectric material layer generates a current according to a temperature difference between the first side and the second side.

主权项

1. A protective cover, removably attached on an outer surface of a mobile device, the protective cover comprising:
an outer protective layer, located on an outermost side of the protective cover away from the outer surface of the mobile device for buffering an external force; a thermo-conductive layer attached on the outer surface of the mobile device, and located on an innermost side of the protective cover adjacent to the outer surface of the mobile device for distributing heat from the outer surface of the mobile device; and a thermoelectric material layer having a first side adjacent to the thermo-conductive layer and a second side adjacent to the outer protective layer, the thermoelectric material layer being configured for generating a current according to a temperature difference between the first side and the second side, wherein the mobile device is a heat source while the mobile device is operating; wherein a connection point is disposed on the outer surface of the mobile device, and the protective cover further comprises: a circuit coupled between the connection point and the thermoelectric material layer, wherein the circuit is configured for transmitting the current to the connection point to feed back the current to the mobile device to thereby recycle a waste heat by the thermoelectric material layer disposed in the protective cover; wherein the waste heat is generated by the mobile device.
