[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the fitting of the wing edge, the clamping hole, and the guard plate nut clip, facilitates the installation of the bottom guard plate on the bottom of the car's rear compartment using bolts. Through the setting of the sound insulation plate, after the connecting screw passes through the connecting through groove and is threadedly connected to the connecting nut, the sound insulation plate and the bottom guard plate can form a whole. With the assistance of the internal wave-shaped sound insulation pad, the bottom guard plate of this rear compartment has the function of sound insulation and achieves the purpose of good sound insulation effect.

[0016] 2. By adding reinforced convex strips, this utility model can improve the strength of the bottom guard plate itself. By adding positioning cones and mating grooves, it can provide positioning assistance when the bottom guard plate and the sound insulation plate are fitted together. Attached Figure Description
