## Background
BACKGROUND
1. Technical Field
The present disclosure relates to electronic device covers, and particularly to a cover with a charging function.
2. Description of Related Art
Currently, some electronic device covers include an induction coil that must be placed onto a charging base to charge the electronic device. However, because only one coil is provided, orientation of the electronic device during charging is limited making it difficult for users to continue using the device while it is being charged.

FIG. 2 is an isometric view of a first induction coil of the cover of FIG. 1 being used to charge the electronic device.
FIG. 3 is an isometric view of a second induction coil of the cover of FIG. 1 being used to charge the electronic device.
FIG. 4 is an isometric view of a third induction coil of the cover of FIG. 1 being used to charge the electronic device.



DETAILED DESCRIPTION
Referring to FIG. 1, a cover 1 includes a top cover 10 and a bottom cover 20 connected by a hinge 30. The cover 1 further includes an interface 40 for connecting to an electronic device (not shown). A first induction coil 201 is embedded in the bottom cover 20 and is electrically connected to the interface 40.
As shown in FIG. 2, the bottom cover 20 is placed onto a charging base 2 having a primary induction coil (not shown) to charge the electronic device.
The top cover 10 is substantially sheet-shaped and transversely divided into four parts. Every adjacent two parts can be folded relative to each other a certain degree such that the top cover 10 is folded to support the electronic device at a certain degree. The four parts respectively include imbedded therein a second induction coil 101, a third induction coil 102, a battery 103, and a solar panel 104. The second induction coil 101 and the third induction coil 102 are both connected to the interface 40 and the battery 103. The battery 103 is connected to the interface 40. The solar panel 104 has surfaces exposed from the top cover 10 and is connected to the interface 40 and the battery 103. The solar panel 104 can provide supplementary charging when exposed to light and the cover 1 is not placed on the charging base 2 in folded position.
As shown in FIGS. 3-4, the top cover 10 may be folded to form a triangular shape to support the electronic device connected to the cover 1 at a certain degree for ease of use during charging. In the embodiment, the top cover 10 is made of flexible material for ease of folding.
As shown in FIG. 3, the second induction coil 101 is horizontally placed onto the charging base 2 with the solar panel 104 overlapping the second induction coil 101. Thus, the electronic device can be supported at a comfortable angle for users during charging.
As shown in FIG. 4, the third induction coil 102 is placed onto the charging base 2 which is placed in the horizontal plane, the solar panel 104 overlaps the second induction coil 101. Thus, the electronic device can be supported by the cover 1 at the degree as shown in FIG. 4 while the electronic device is charged by the third induction coil 102.
In the embodiment, when the electronic device is not connected to the cover 1, the second induction coil 101 or the third induction coil 102 can be placed onto the charging base 2 to charge for the battery 103. The solar panel 104 also can be used to charge the battery 103.
In other embodiments, the top cover 10 may instead be transversely divided into at least three parts provided at least one part includes an induction coil and the cover can be folded to support the electronic device. If only three parts are provide the solar panel 104 may be omitted or imbedded in one of the remaining parts with another of the components.
In other embodiments, the cover 1 may include more than just a top and bottom cover, e.g. a three-fold cover.
Although, the present disclosure has been specifically described on the basis of preferred embodiments, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
