AI Technical Summary
Traditional underbody protection plates cover a small area of the vehicle's underside, affecting the flatness of the vehicle's underside and resulting in poor wind resistance.
Design a vehicle bottom structure including an exhaust pipe, a bottom guard plate and a heat insulation structure. The bottom guard plate extends along a first direction, the heat insulation structure is disposed on the surface of the bottom guard plate, and the exhaust pipe is located on the heat insulation structure to form an integral structure, thereby increasing the coverage area of the bottom guard plate. A heat insulation layer and a heat insulation cover are disposed on the bottom guard plate to block heat transfer.
It improved the flatness of the vehicle's underbody, enhanced the heat insulation of the underbody protection plate, reduced wind resistance, improved vehicle safety performance, and reduced production costs.
