Double-outlet decorative cover and car

Abstract

The invention relates to the field of cars, and provides a double-outlet decorative cover and a car. The double-outlet decorative cover comprises a tee-joint exhaust pipe which comprises an inlet pipe segment and two outlet pipe segments; the center axes of the two outlet pipe segments are parallel with each other; the center axis of the inlet pipe segment and the center axes of the two outlet pipe segments are perpendicular and located in the same plane; the inlet pipe segment and the outlet pipe segments are smoothly connected; and the double-outlet decorative cover further comprises a flow guiding plate arranged in the tee-joint exhaust pipe so as to guiding gas flow of the tee-joint exhaust pipe and make the gas flow evenly distributed into the two outlet pipe segments. According to the double-outlet decorative cover, the flow guiding plate is arranged in the tee-joint exhaust pipe, so that the gas flow in the tee-joint exhaust pipe can be reasonably guided and the gas flow can be evenly distributed into the two outlet pipe segments as much as possible, and the appearance color difference and the gas flow noise problem caused when the flow speeds are not uniform are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a double-exit decorative cover and an automobile with the double-exit decorative cover. Background technique [0002] In recent years, automobile companies have developed rapidly. In order to provide customers with more choices, various car companies have launched multiple versions of models. Many models can easily distinguish the configuration from the appearance, one of which is the layout of the tailpipe of the exhaust system. It can be subdivided into four types: one-sided single tailpipe, double-sided single tailpipe, single-sided single tailpipe and double-sided double tailpipe. Among them, especially the configuration of double tailpipes, many factors such as weight and cost need to be considered. Therefore, The structural design of the double tailpipe is very important. If the car is designed to extend two tailpipes directly from the side of the muffler, the weight of...

[0002] In recent years, automobile companies have developed rapidly. In order to provide customers with more choices, various car companies have launched multiple versions of models. Many models can easily distinguish the configuration from the appearance, one of which is the layout of the tailpipe of the exhaust system. It can be subdivided into four types: one-sided single tailpipe, double-sided single tailpipe, single-sided single tailpipe and double-sided double tailpipe. Among them, especially the configuration of double tailpipes, many factors such as weight and cost need to be considered. Therefore, The structural design of the double tailpipe is very important. If the car is designed to extend two tailpipes directly from the side of the muffler, the weight of the exhaust system will be heavy. Therefore, a better solution is to extend a single tailpipe from the side of the muffler , set a double outlet trim cover at the outlet end of the single tail pipe, and then pass through a double outlet trim cover (usually including a three-way exhaust pipe, which includes an inlet pipe section for exhausting with the automobile muffler In addition, the three-way exhaust pipe also includes two outlet pipe sections, facing the rear of the car to obtain a double outlet appearance) to achieve a double outlet appearance equivalent to two tailpipes, which only meets the appearance requirements, but the problem is that, from The gas entering the tee exhaust pipe from the inlet pipe section cannot be evenly distributed to the two outlet pipe sections, resulting in different appearance colors of the exhaust port ends of the two outlet pipe sections, and due to the uneven distribution of airflow, it will cause the The problem of airflow noise in the outlet pipe section is more prominent
