DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 

        (1) A 2-pin connector is used to connect a mobile power source to a PD HUB PCB motherboard 1. The USB-C input bus 4 is connected to an external power source and ensures that the mobile device is always powered. (2) Three 5-pin connectors and one 12-pin connector are used to connect external mobile devices such as fingerprint recognition module and passport recognizer to ensure the stability of OTG data transmission function, more expandability, and high compatibility of external mobile devices. (3) By controlling the OTG and the switch 2 for charging in the forward and reverse directions, the OTG and the charging function are successfully integrated, and the switch can be fast-charged, and the OTG function can be realized by the switch, which is simple and easy to use. (4) The connection between the external mobile device and the PCB main board (1) adopts a flexible flat connecting cable, which greatly saves space and its flexibility reduces the defective rate during assembly. (5) By optimizing the circuit design, the temperature of the chip U11 of the PD HUB PCB main board 1 is reduced to 42 degrees Celsius, which greatly reduces the failure rate of the utility model and the external mobile device due to excessive temperature. (6) The PD HUB PCB main board (1) is designed with a 4-layer structure to reduce the size of the utility model and save space. (7) The OTG function indicator (9) is used to indicate the status of the OTG function, and the charging and power indicator (10) indicate the amount of the mobile power. When the charger charges the battery and the mobile device, the corresponding power source is charged. The LED light will flash. The above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and variations, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also The scope of protection of the utility model.
