AI Technical Summary

Technical Problem

The poor dynamic stiffness of the front roof beam assembly in existing vehicles leads to problems such as resonance and roaring noise during driving.

Method used

Design a front top crossbeam assembly, including a front top crossbeam, a top cover outer plate and connecting brackets. By setting multiple connecting brackets in the open through slot, the first support cavity is divided into multiple sub-cavities, and they are connected by spot welding to form a multi-layer connection structure to improve the structural strength and rigidity.

Benefits of technology

While simplifying the structure and reducing weight, it improves dynamic stiffness, effectively reduces resonance and noise problems during driving, and enhances the vehicle's resistance to deformation and noise suppression.
