[0001] This invention relates to the field of vehicle body structure technology, specifically to a four-in-one integrated mounting bracket structure for automotive control systems. Background Technology

[0002] New energy vehicles have become an important development direction for the automotive industry. Among them, hybrid vehicles are particularly significant. The advantages of hybrid powertrain technology, such as strong hill-climbing ability, long driving range, and energy saving, make hybrid powertrains a promising market prospect in the future. However, the use and layout of hybrid powertrains are complex, involving multiple systems and functions. Multiple controllers need to be installed in the limited space of the vehicle's front compartment, making installation and removal cumbersome. Moreover, the controllers are prone to damage due to bumps and vibrations during vehicle operation, posing safety hazards.
