As shown in fig. 3, the embodiment further provides a vehicle including an engine body 5, an engine exhaust structure 6 disposed on the rear side of the engine body 5, and a cooling fan (not shown) disposed on the front side of the engine body 5, wherein the trim cover body 1 is located above the engine body 5, the third flow guide structure 4 is located above the engine exhaust structure 6, and the second flow guide structure 3 is located at a position corresponding to a connection position of the engine body 5 and the engine exhaust structure 6.
When the existing vehicle is in a standing working condition after running, the engine exhaust structure 6 still radiates heat to heat surrounding air and parts, which may cause damage to the parts around the engine exhaust structure 6. When the vehicle in this embodiment is in the stationary condition after traveling, the engine is turned off and the cooling fan is still rotated, as shown in fig. 4, the cold air flow provided by the cooling fan is blown toward the trim cover body 1 from front to back, the cold air flow is divided by the trim cover body 1, a part of the cold air flow flows toward the lower side of the trim cover body 1, and the other part of the cold air flow flows toward the upper side of the trim cover body 1. After a part of cold air flow flows to the lower side of the decorative cover body 1, the part of cold air flow flows to the second drainage structure 3 along the drainage groove from front to back, the second drainage structure 3 can enable the air flow in the drainage groove to flow downwards, and the second drainage structure 3 guides the cold air flow to be specifically blown to the joint of the engine body 5 and the engine exhaust structure 6 due to the fact that the position of the second drainage structure 3 corresponds to the position of the joint of the engine body 5 and the engine exhaust structure 6, and the cooling effect on components such as an actuator, a wire harness and a connector assembly laid in the area is obvious; a part of cold air flow flows to the upper side and the back of the decorative cover body 1, the part of cold air flow flows to the third flow guiding structure 4 from front to back along the decorative cover body 1, the third flow guiding structure 4 can guide the air flow positioned above the decorative cover body 1 to flow downwards, and the third flow guiding structure 4 is positioned above the engine exhaust structure 6, therefore, the third flow guiding structure 4 guides the cold air flow to cross over the engine exhaust structure 6 and enables the cold air flow to flow between the engine exhaust structure 6 and the pressure chamber plate and between the engine exhaust structure 6 and the firewall, thereby effectively inhibiting the hot air convection rising effect of the peripheral area of the engine exhaust structure 6, the firewall and the pressure chamber plate under the static working condition, therefore, enough cold air flow can flow between the engine exhaust structure 6 and the pressure chamber plate and between the engine exhaust structure 6 and the firewall, and low-temperature-resistant internal and external decoration parts and NVH parts which focus on the area are protected.
