There are many components in a car, and the power distribution box is an important component. Usually, the power distribution of the whole vehicle is divided into primary distribution and secondary distribution. After the primary distribution box uses a large-capacity fuse to complete the initial power distribution, it distributes the power to the secondary distribution box for further subdivision. The secondary distribution box is divided into the body distribution box and the chassis distribution box. At present, there are two types of power distribution methods for vehicle power: one is to use a separate primary distribution box and two secondary distribution boxes (body distribution box and chassis distribution box), which totals three distribution boxes; such a structure will result in a large number of distribution boxes, high investment costs, occupy a large space in the overall layout process, use more wiring harnesses, poor stability and high subsequent costs; the second is to use a primary distribution box and a body distribution box, and no chassis distribution box is set; although such a structure reduces one distribution box, some chassis electrical appliances, such as: electronically controlled dryers, urea pipe heating, post-processing power supply, etc., all use the power supply provided by the body distribution box, resulting in more wires in the power supply circuit of the chassis electrical appliances, causing the connecting harness from the body to the chassis to be too bloated, making the harness layout difficult, and the stability is poor and the cost is high.
