A vehicle distribution box

Abstract

The invention discloses a vehicle-mounted distribution box which is applied to a vehicle and comprises a box body and a power distribution assembly. The power distribution assembly is arranged in the box body and comprises a power interface, a voltage conversion module, a protective module and an output interface. One end of the power interface penetrates through the box body and is used for receiving input voltage when the power interface is connected into a power supply. The power supply is an external power supply arranged outside the vehicle or a self-contained power supply on the vehicle. The voltage conversion module is connected with the other end of the power interface and used for converting the input voltage into two or more paths of sub voltage with different voltage quality. The protective module is connected with the voltage conversion module and used for monitoring and protecting the two or more paths of sub voltage. The output interface is used for outputting the two or more paths of sub voltage to two or more to-be-powered parts of the vehicle.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a vehicle-mounted power distribution box.
