A-pillar exterior trimming panel and a vehicle

Abstract

The invention relates to an A-pillar exterior trimming panel and a vehicle, the A-pillar exterior trimming panel is arranged on the outer side of an A pillar of the vehicle, the vehicle further comprises a front windshield window and a side window which are located on the two sides of the A pillar, the A-pillar exterior trimming panel comprises an exterior trimming panel body, and the exterior trimming panel body is provided with an air inlet, an air outlet and a flow guide channel communicating with the air inlet and the air outlet; the air inlet is formed in the side of the front windshield window, and the air outlet is formed in side of the side window. According to the A-pillar exterior trimming panel and the vehicle, when passing through the surface of the A pillar, airflow is exhausted from the air outlet through the flow guide channel from the air inlet of the exterior trimming panel body, the air outlet is formed in the side of the side window, and therefore the airflow can be concentrated to be tightly attached to the side window to be accelerated, the separation area of the airflow at the A pillar is reduced, kinetic energy consumption is reduced, and the fuel economy of the vehicle is further improved; in addition, the body-in-white of an original vehicle cab does not need to be changed, the design is improved only for the A-pillar exterior trimming panel, and therefore the A-pillar exterior trimming panel can be applied to different vehicle types, the manufacturing cost is low, the design period is short, and meanwhile maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of vehicle drag reduction structure design, in particular to an A-pillar exterior trim panel and a vehicle. Background technique [0002] Under the increasingly stringent regulations and fierce market competition, the fuel economy of commercial vehicles is an important indicator to determine the commerciality of commercial vehicles, and improving aerodynamics is one of the important means. [0003] In the existing commercial vehicle design, the airflow is separated greatly near the A-pillar, resulting in large wind resistance of the vehicle, which in turn increases energy loss, which is not conducive to the fuel economy of the vehicle. Contents of the invention [0004] Based on this, it is necessary to provide a solution for the existing gas-fired commercial vehicle design, where the airflow is greatly separated near the rearview mirror and the A-pillar, resulting in large wind resistance of the vehicle, ...
