Abstract

A bracket-type wireless charger, including a box body having a charging circuit and a transmitting plate having a transmitting coil. An adapter plate is arranged between the transmitting plate and the box body. An upper end of the adapter plate is hinged through interference fit to a lower part of a back surface of the transmitting plate. A lower end is hinged through interference fit to a middle part of a top surface of the box body. The box body has a groove for accommodating the adapter plate. The two ends of the adapter plate are hinged through interference fit to the box body and the transmitting plate respectively, and the position and an inclination angle of the transmitting plate relative to the box body can be adjusted through rotation of the adapter plate, so as to adapt to the positions of wireless charging receiving coils of different electronic equipment.
