Abstract

The present application relates to a vehicle-mounted voltage reducing device and a vehicle-mounted system. The vehicle-mounted voltage reducing device includes a voltage reducing device, a second connector, a connection assembly and a bidirectional level converter. The present application is provided with the bidirectional level converter, and the bidirectional level converter converts the first K communication level signal generated by the OBD device and the second K communication level signal generated by the vehicle-mounted device Exchange level signals, and transmit the first K communication level signal and the second K communication level signal to the OBD device and the vehicle-mounted device through the second connector and the connecting component respectively , so as to realize the communication between the OBD device and the vehicle-mounted device. The vehicle-mounted voltage reducing device provided by the present application solves the poor communication effect between the vehicle-mounted equipment and the vehicle in the prior art, and achieves the technical effect of realizing the communication between the vehicle-mounted equipment and the vehicle.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a vehicle-mounted voltage reducing device and a vehicle-mounted system. Background technique [0002] Vehicle-mounted equipment refers to the electronic systems and products used to increase the functionality of the vehicle, mainly including vehicle-mounted audio systems, navigation systems, vehicle information systems, and vehicle-mounted home appliances. At present, there are mainly two ways to obtain power for vehicle-mounted equipment. One is to obtain power from the fuse box, and then use the power obtained from the fuse box to reduce the voltage and supply it to the vehicle-mounted equipment. The other is to take power through the car cigarette lighter, and also use the power taken from the car cigarette lighter to supply the car equipment after step-down processing. However, no matter which of the above power-taking methods is adopted, the communication effect ...
