Abstract: A mobile terminal protection frame (100), comprising a frame body (120), a first snap-in part (140), a second snap-in part, and a connecting part; the frame body (120) surrounds the edge of a mobile terminal (20); an opening (122) used for insertion of a plug (240) of a battery case (200) is formed on the frame body (120) and corresponds to a charging port of the mobile terminal (20). The first snap-in part (140) is fixedly connected on one side of the frame body (120) and is used for snapping the front surface of the mobile terminal (20). The second snap-in part is fixedly connected on the other side of the frame body (120) and is used for snapping the back surface of the mobile terminal (20). The connecting part is fixedly connected with the second snap-in part and can be detachably connected with the battery case (200).

Abstract: A mobile terminal protection sleeve (100), comprising a sleeve body (120), communication terminals (140), an internal lead, a flexible data line (160), and a flexible connector (180). The sleeve body (120) can surround the edge of the mobile terminal, and is provided with a plurality of terminal accommodating holes and an opening, and the opening corresponds to the communication interface of the mobile terminal. A plurality of communication terminals (140) is provided for communicationally connected to an external device (200). The plurality of communication terminals (140) are embedded in the plurality of terminal accommodating holes in one-to-one correspondence. The internal lead is wrapped in the sleeve body (120), and one end of the internal lead is electrically connected with the communication terminals (140). One end of the flexible data line (160) is connected with the sleeve body (120), and the other end of the internal lead is electrically connected with the flexible data line (160).

Abstract: An intelligent identification charging method includes the steps of: monitoring the voltage signal at the detection pin of the connector; generating a first voltage control signal according to the voltage signal at the detection pin; regulating the output voltage according to the first voltage control signal; and outputting the output voltage via the first charging pin of connector. A corresponding voltage is output by gathering a signal at the detection pin of the connector, and controlling the voltage according to the gathered signal at the detection pin so as to charge for the different electronic devices, which solves the problem that power adapters of all kinds of electronic products are not matched with each other. The intelligent identification charging device can be compatible with the connection of a USB interface, so that it can charge for the electronic device by the USB connector.
