Abstract

An on-board diagnostic (OBD) adapter includes an input connector, a first output connector and a second output connector. The input connector is electrically connected to the first and second output connectors through a circuit board. The input connector is inserted into a socket of the OBD to capture vehicle driving information from the OBD and transmit the vehicle driving information to the first and second output connectors. The first output connector is formed in a specification the same as the socket of the OBD. The second output connector is formed in a specification different from the socket of the OBD. The adapter provides connection with the OBD with the same or different connector to improve usability.

Claims

1. An on-board diagnostic adapter inserted into a socket of an on-board diagnostic to capture vehicle driving information of the on-board diagnostic, comprising:

an input connector electrically connected to a circuit board and inserted into the socket to connect to the on-board diagnostic;

a first output connector which is electrically connected to the circuit board to form electric connection with the input connector and formed in a specification the same as the socket of the on-board diagnostic, the adapter including a first transmission path to transmit the vehicle driving information from the input connector to the first output connector; and

a second output connector which is electrically connected to the circuit board to form electric connection with the input connector and formed in a specification different from the socket of the on-board diagnostic, the adapter including a second transmission path to transmit the vehicle driving information from the input connector to the second output connector.

2. The on-board diagnostic adapter of claim 1 further including a housing to hold the circuit board, the housing including a first opening, a second opening and a third opening to couple respectively with the input connector, the first output connector and the second output connector.

3. The on-board diagnostic adapter of claim 2, wherein the input connector and the first output connector include respectively a groove and the housing includes flanges respectively on the first opening and the second opening to latch on the groove.

4. The on-board diagnostic adapter of claim 1, wherein the second output connector is selectively a USB, a Mini USB or a Micro USB interface.

5. The on-board diagnostic adapter of claim 1, wherein the socket, the input connector and the first output connector respectively conform to J1962 DLC specification.

6. The on-board diagnostic adapter of claim 1, wherein the input connector includes sixteen input pins connected to the circuit board and the first output connector includes sixteen output pins connected to the circuit board.

7. The on-board diagnostic adapter of claim 6, wherein the circuit board includes a transceiver unit connected to the input pins to identify the vehicle driving information, a processing unit connected to the transceiver unit to convert the vehicle driving information, and a transmission unit connected to the processing unit to transmit the converted vehicle driving information.

8. The on-board diagnostic adapter of claim 7, wherein the transceiver unit includes a plurality of transceivers connected to varying input pins to receive the vehicle driving information from various vehicle makers.

9. The on-board diagnostic adapter of claim 8, wherein the circuit board includes a first manual switch connected to the transceivers and the processing unit to form electric connection between the processing unit and one of the transceivers.

10. The on-board diagnostic adapter of claim 9, wherein the second output connector is electrically connected to an external device which includes a second manual switch.

11. The on-board diagnostic adapter of claim 7, wherein the transmission unit is connected to the second output connector.

12. The on-board diagnostic adapter of claim 7, wherein the transmission unit is a wireless transceiver.

13. The on-board diagnostic adapter of claim 1, wherein the first output connector includes at least one switch device and at least one notch to hold the switch device, the switch device being electrically connected to the input connector, the first output connector and the second output connector to switch the adapter to the first transmission path or the second transmission path.
