Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to an automobile PDU bracket structure. Background Art

[0002] At present, in most new energy hybrid vehicles, the generator and drive systems often occupy most of the layout space in the front cabin, so the space for arranging various electrical components and their control systems in electric vehicles will be limited; PDU (Power Distribution Unit) is called "power distribution unit", which distributes the heat energy of the entire vehicle to different electrical devices and receives instructions from the central power management system (Central Power Management System). This provides the most stable and reliable power supply for other devices in the vehicle system, and also enables the system manager to monitor and feedback the power usage in real time. As the main distribution center of the power supply, the automotive PDU converts the electrical energy into appropriate voltage, current, frequency and light parameters, and then transmits it to various consumer devices. Therefore, PDU must be safe, stable and reliable. The PDU controller and other peripheral electrical components of some existing models are installed at the front cabin longitudinal beam position of the vehicle through multiple separate brackets. Due to the compact space there, it is difficult to arrange, occupies a lot of space, and often interferes with the engine suspension. Therefore, it is necessary to invent a vehicle PDU bracket structure. Utility Model Content
