Description

Technical Field

[0001] This utility model relates to the field of automotive battery pack installation technology, and more specifically, to a new energy vehicle battery pack bracket assembly. Background Technology

[0002] The battery pack of a new energy vehicle is the core energy source of an electric vehicle, equivalent to the combination of "fuel tank + engine" in a traditional fuel vehicle. It not only determines the vehicle's range, power performance, safety, and lifespan, but is also one of the components that accounts for the highest proportion of the overall vehicle cost (usually 30% to 40%).

[0003] The battery pack bracket assembly in new energy vehicles is a key connecting structural component between the battery system and the vehicle chassis, undertaking important functions such as load bearing, fixation, buffering, protection, and safe load transfer. It not only affects the installation accuracy and reliability of the battery pack, but also directly relates to the safety, NVH performance (noise, vibration, and harshness), and collision safety of the entire vehicle.

[0004] The battery pack is mounted on the vehicle frame via a battery pack bracket. In related technologies, the battery pack bracket is a rigid structure that can only accommodate a single type of battery pack. Its size is not adjustable, which limits its use. Furthermore, the installation of the battery pack is inconvenient and unstable, and it is prone to failure. Utility Model Content
