Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a PDU integrated bracket structure and a vehicle. Background Art

[0002] The operating conditions of new energy commercial vehicles are relatively complex, and the structural requirements for the high-voltage electrical parts are relatively high, especially for the integrated bracket structure that carries the all-in-one controller and its performance requirements are more stringent.

[0003] However, the PDU (Power Distribution Unit) integrated brackets currently on the market are often large and heavy, which does not meet the requirements of lightweighting and cost reduction. In addition, the PDU integrated bracket has a low degree of integration and cannot meet the technical requirements of compact space and high integration of the entire vehicle. In addition, due to the unreasonable layout of the PDU in the entire vehicle, the length of the high-voltage wire harness connected to the PDU is often unreasonable, causing the high-voltage wire harness to be too long and too heavy. The low degree of integration means that more parts of the entire vehicle need to be assembled on the final assembly line, which greatly reduces the assembly efficiency of commercial vehicles, seriously affects the production rhythm of new energy commercial vehicles, and increases the production cost of the entire vehicle.

[0004] Therefore, a PDU integrated bracket structure and a vehicle are needed to solve the above problems. Summary of the invention
