When the electronic device adopts wireless charging, the first magnetically conductive part faces the receiving coil of the electronic device, and the second magnetically conductive part faces toward the charging coil of the charger. The transmitting coil, and then the magnetic induction lines generated during charging, will preferentially pass through the path with higher magnetic permeability, that is, the number of magnetic induction lines passing through the bracket will be reduced through the first magnetic permeable part and the second magnetic permeable part, thereby reducing the The eddy current attempt on the bracket reduces the possibility of heating the bracket and ensures the wireless charging effect of electronic devices.
