Abstract

The invention relates to a vehicle-mounted voltage reduction device and a vehicle-mounted system. The vehicle-mounted voltage reduction device comprises a voltage reduction device, a second connector,a connecting assembly and a bidirectional level converter. According to the invention, the bidirectional level converter is arranged, and the bidirectional level converter exchanges the first K communication level signal generated by an OBD device with the second K communication level signal generated by a vehicle-mounted device; and the first K communication level signal and the second K communication level signal are respectively transmitted to the OBD device and the vehicle-mounted device through the second connector and the connecting assembly, so that the communication between the OBD device and the vehicle-mounted device is realized. According to the vehicle-mounted voltage reduction device, the problem that in the prior art, the communication effect between the vehicle-mounted device and the vehicle is poor is solved, and the technical effect of achieving communication between the vehicle-mounted device and the vehicle is achieved.

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 ...
