[0084] That is to say, the upper end of the rear side outer decorative component 100 starts above the triangular window area 2001, the lower end extends to the lower boundary of the wheel arch, the front end is adjacent to the rear door boundary of the vehicle, and the rear end extends to the water trough area 2002. Among them, the air guide channel is formed between the first edge 101 and the second edge 102, that is, in the second direction Z, the air guide channel is formed at the upper end of the rear side decorative component.

[0085] Further, in some embodiments, as Figure 8 shown, the rear side outer trim 1 includes an outer trim 1 and an air duct inner panel 2, and the outer trim 1, the air duct inner panel 2 are connected to the vehicle body structure 200. The air duct inner panel 2 is located between the outer trim 1 and the vehicle body structure 200, and the air guide channel is formed between the air duct inner panel 2 and the outer trim 1. In this embodiment, the above-mentioned air guide channel is formed between the air duct inner panel 2 and the outer trim 1, and the setting of this air guide channel does not affect the appearance of the outer trim 1, ensuring the integrity and aesthetics of the appearance of the outer trim 1. Among them, the direction in which the outer trim 1, the air duct inner panel 2 and the vehicle body structure 200 are sequentially arranged is defined as the third direction Y, and the third direction Y is also the left-right direction of the vehicle. The third direction Y is perpendicular to both the first direction X and the second direction Z.
