An internet device and an automatic switching method, apparatus and circuit for a charging interface of an internet device are disclosed. The device includes a device charging interface (20), a dock charging interface (30), a charging loop (40) and an automatic switching apparatus (10) for a charging interface. The method includes: when external power supply is connected into the device (S001), judging whether a dock charging interface a the device is in place (S002), if so, isolating a device charging interface of the device and at the same time, connecting a charging loop of the device through a dock charging interface of the device (S003); otherwise, isolating the dock charging loop of the device and at the same time, connecting the charging loop of the device through the device charging interface of the device (S004). The device is convenient to implement and has the advantages of reliable performance and low cost. |
