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.
