Abstract: This disclosure discloses a wireless charging device and a wireless charging base. The wireless charging device includes an alignment mechanism and at least two transmit coils. Each transmit coil wirelessly charges a corresponding electronic device. Charging regions formed by the transmit coils on a charging plane are interconnected or overlap. The alignment mechanism drives each transmit coil to be aligned with a receive coil in a corresponding electronic device, and the transmit coil wirelessly charges the corresponding electronic device. The charging regions formed by the transmit coils are contiguous, and the charging regions covered by the transmit coils have no spacing in between and form a contiguous charging plane, in other words, a plurality of transmit coils form a relatively large charging region.
