Power distribution box for automobiles, automobiles

Abstract

The invention discloses a distribution box used for an automobile and the automobile and belongs to the field of electronic and electrical engineering. The distribution box comprises a shell, a powersupply distribution unit controller arranged in the shell, a micro-controller unit plug-in port, a battery plug-in port and a heater plug-in port, wherein the micro-controller unit plug-in port, the battery plug-in port and the heater plug-in port are formed in the shell. The power supply distribution unit controller is provided with a first detecting port, and the micro-controller unit plug-in port, the battery plug-in port and the heater plug-in port are all provided with interlocking signal ends. The positive electrode of the first detecting port is connected with the positive electrode ofthe interlocking signal end of the heater plug-in port; the negative electrode of the interlocking signal end of the heater plug-in port is connected with the positive electrode of the interlocking signal end of the battery plug-in port; the negative electrode of the interlocking signal end of the battery plug-in port is connected with the positive electrode of the interlocking signal end of the micro-controller unit plug-in port; and the negative electrode of the interlocking signal end of the micro-controller unit plug-in port is connected with the negative electrode of the first detecting port. The situation that required circuits and circuit structures are detected in a plug-in mode is achieved in a simplified mode.

Description

technical field [0001] The invention relates to the field of electronics and electricity, in particular to a power distribution box for automobiles and automobiles. Background technique [0002] With the increasing shortage of global oil resources and serious environmental pollution, various energy-saving and environmentally friendly new energy vehicles are emerging, such as pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell vehicles and so on. With the continuous advancement of new energy vehicle technology and the continuous policy support of various countries, the market size of new energy vehicles has shown a trend of rapid growth year by year. [0003] In a car that can use electric energy as power, the power distribution box is mainly used to distribute power to other power components. It is generally realized in a simple parallel connection: the power supply circuits of each power component are connected in parallel with each other. U...

Problems solved by technology

On this basis, in order to detect whether the plug-in is firmly plugged into the power distribution box, it is necessary to make a line in the power distribution box to lead out the interlock pin of each plug-in port, which not only makes the wiring in the power distribution box complicated, but also takes up A large portion of the number of lead terminals, but also prone to various electrical failures due to shorts or opens at the lead connections
