Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a reinforcing plate for automotive wheel arches. Background Technology

[0002] With increasing demands for strength, safety performance, and lightweighting of automotive wheel arches, it's possible to reduce the number of body structure parts developed using conventional cold stamping methods while achieving equal or higher structural strength. This reduces welding processes and achieves both lightweighting and reinforcement. During the manufacturing process of wheel arch reinforcement plates, stamping dies are used to punch specific areas of the ribs and plate structure, creating pre-defined induced deformation zones. This ensures the wheel hub effectively reinforces itself according to the designed reinforcement pattern during use. The overall connection and internal transition design of the wheel arch reinforcement plates are particularly important in showcasing their effectiveness. Utility Model Content
