Referring to fig. 3 and 6, the wireless charging module 3 includes a charging coil 31, a magnetic conductive sheet 32 and a PCB 33, wherein the charging coil 31 and the magnetic conductive sheet 32 are circular. The charging coil 31 is electrically connected to the PCB 33. The charging coil 31, the magnetic conductive sheet 32 and the PCB 33 are sequentially arranged from top to bottom. The PCB 33 is located at the inner bottom of the shield can 4. A support frame 42 is provided in the shield case 4, and the support frame 42 extends from the inner bottom of the shield case 4 toward the opening 41.
