Notably, the wireless charging pad 20 is removably connected to other charging pads, or permanently connected to other charging pads, or to each other. For example, the wireless charging pad 20 is removably connected with the combining member 30', and each of the wireless charging pad 20 and the combining member 30' are removable, detachable, and/or attached to each other. In yet another embodiment, the combination members 30' may be snap fit to the wireless charging pad 20, but removably attached to each other, for example, at or near the pivot point 35. In another embodiment, the wireless charging pad 20 and the combination member 30' are permanently but movably/pivotally interconnected.

As shown in fig. 8A and 8B, in another embodiment, a plurality of wireless charging boards 20 are arranged in multiple layers in the vertical direction and connected to each other. The combined member 30 "includes at least one strut 37 to vertically support the wireless charging pad 20. Thus, the strut 37 may be a means of support. Other vertical wireless charging pad 20 forms are also possible.

In addition, power may be transferred from one wireless charging pad 20 to a second charging pad through the post 37. In particular, the combined members 30, 30' and 30 "may each transmit power from one wireless charging pad to another linked wireless charging pad under different circumstances. Thus, whenever one wireless charging pad 20 needs to be connected to or include a power source, the power source is thereby transferred to other charging pads that require power, such as through the combination of components 30, 30', and 30 ".

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
