The thickness of the decorative plate 16 is less than the thickness of the mounting plate 11. The thickness of the mounting plate 11 is the same as the thickness of the noise reduction plate 15.
[0018] In this embodiment, the reinforcing plate 12 made of PVC material has the advantages of good sound insulation, good heat insulation and easy processing. By setting the opening 13 and the reinforcing strip 14, the resilience and deformation resistance of the reinforcing plate 12 can be improved, thereby avoiding deformation of the reinforcing plate 12 and thus preventing deformation of the rear luggage compartment trim panel 1.
