Patent attributes
A wireless charging device is configured to charge a terminal and includes a first transmitting coil and a second transmitting coil. The first transmitting coil and the second transmitting coil are in a layered distribution, and the second transmitting coil is movable between a first position and a second position along a direction perpendicular to a central axis of the second transmitting coil. When the second transmitting coil is located at the first position, an orthographic projection of the second transmitting coil on a preset plane partially coincides with an orthographic projection of the first transmitting coil on the preset plane, where the preset plane is perpendicular to the central axis. When the second transmitting coil is located at the second position, the orthographic projection of the second transmitting coil on the preset plane does not coincide with the orthographic projection of the first transmitting coil on the preset plane.
