Technical Field

[0002] With the development of new energy vehicles, the application of new energy technology is no longer limited to the traditional passenger cars and commercial buses, and has gradually penetrated into mining trucks and commercial vehicles. At present, most of the mining trucks used in mining areas are pure electric mining trucks, which rely entirely on power battery systems as energy sources to drive the vehicle and the upper system to work; in actual use, pure battery systems cannot meet the long-term high-power use needs of mining trucks. With the development of extended-range mining trucks, extended-range mining trucks are gradually emerging, and extended-range mining trucks require high-end power distribution systems to cooperate with them.

[0003] Because the mining trucks require a lot of power when working, and the current generated by the high-voltage distribution structure is also relatively large, it will inevitably generate a lot of heat and cause the temperature inside the distribution structure to rise, which will inevitably affect the stability. At the same time, because the mine is dusty, if the heat dissipation port is blocked, it will also affect the heat dissipation of the distribution structure.

[0004] Therefore, we proposed a high-voltage power distribution system for extended-range mining trucks to solve the above-mentioned problems. Utility Model Content
