[0037] Embodiment 1:

[0038] like Figures 1 to 10 As shown, a vehicle-mounted dual-interface USB fast charging device includes:

[0039] Main body 1, interface socket 2, circuit board 3, component module 4, connector 5 and base 6;

[0040] The body 1 is arranged in a square shape, the interface socket 2 and the connector 5 are arranged at two ends of the body 1, and the interface socket 2 and the connector 5 are arranged in two groups, and the interface socket 2 and the connector 5 are arranged in a one-to-one correspondence;

[0041] The interface socket 2 is connected to an external power line, the connector 5 is connected to a vehicle power supply, the circuit board 3 is arranged in the body 1, the circuit board 3 connects the interface socket 2 and the connector 5, the component module 4 is arranged on the circuit board 3, the component module 4 controls two groups of the interface sockets 2, and the base 6 seals the end opening of the body 1 where the connector 5 is installed;

[0042] The interface socket 2 can be slidably flipped and adjusted relative to the body 1 to switch the direction of the plug-in port 21 on the interface socket 2.

[0043] The two groups of interface sockets 2 are both USB interface sockets. Further, one of the two groups of interface sockets 2 is a Type A interface socket, and the other is a Type C interface socket, or both groups are Type A interface sockets.

[0044] In addition, buckles 11 for mounting and connecting with vehicle-mounted components are protruded from the side walls of the main body 1 .

[0045] The rated output current of the USB port of the utility model is: 1.5A, output power ≤7.5W, input voltage: 9~16V, no-load current: <5mA, TypeA supports BC1.2, USB2.0 protocol, input voltage 13.5V, current 1±0.2A, output voltage: DC 5V±0.25V, TypeC supports Huawei 66W fast charging, output voltage: DC11V, current 6A.

[0046] Among them, the specific setting structure of the interface socket 2, the circuit board 3, the component module 4, and the connector 5 connecting the circuit of the utility model is as follows Figure 6 As shown, the specific connection structure of the circuit is similar to the structure in the utility model patent application number 202221210230.7, so the utility model will not be described in detail.

[0047] Here, the main difference between the present invention and the existing USB fast charging device is that, as a preferred adjustment structure, the interface socket 2 is arranged in an L shape, and the side wall of the interface socket 2 is arranged with an L-shaped slide groove 22.

[0048] In addition, a limiting block 12 that cooperates with the sliding groove 22 is provided at a position on the main body 1 that cooperates with the interface female seat 2 .
