Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an automotive aftertreatment bracket. Background Technology

[0002] With increasingly severe air pollution, national emission standards for engines are becoming more stringent. Gas treatment devices are installed both before and after the engine to ensure emissions meet standards. These after-treatment devices integrate multiple processing units, resulting in complex structures and significant size and weight, thus requiring high structural strength from the brackets. Current brackets often use L-shaped or A-frame designs, which are heavy, space-consuming, difficult to install, prone to vibration breakage, have low material and space utilization, and are costly. Furthermore, existing brackets use sheet metal welding for fixing and splicing, a cumbersome production process with inconsistent quality, and cannot meet the assembly requirements of lightweight vehicles.
