Wireless charger

The invention belongs to the technical field of wireless chargers, and particularly relates to a wireless charger which comprises a charging panel, a bottom shell and a primary coil, the charging panel is installed on the upper side of the bottom shell in a hinged mode, and the primary coil is installed in the bottom shell in a sliding mode. When the charging panel swings relative to the bottom shell, the primary coil slides towards one side of the lower hem of the charging panel. According to the wireless charging equipment designed by the invention, after the charging equipment is placed on the charging panel, if the placement position of the charging equipment deviates from the center, the primary coil can slide towards the placement position of the charging equipment through transmission of a first gear, a second gear, a swing frame, a sliding plate, a spring, a telescopic rod and a fixed plate under the gravity action of the charging equipment; the primary coil is basically opposite to the charging equip
