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.
本发明涉及一种A柱外饰板及车辆,A柱外饰板设于车辆的A柱外侧,车辆还包括位于A柱两侧的前挡风窗和侧窗,A柱外饰板包括外饰板本体,设有进风口、出风口以及连通进风口和出风口的导流通道;其中,进风口设于前挡风窗侧,出风口设于侧窗侧。本发明提供的A柱外饰板及车辆,气流在经过A柱表面时,由外饰板本体的进风口经导流通道从出风口排出,而出风口设于侧窗侧,从而使气流得能够集中至紧贴侧窗加速,因此,减小气流在A柱处的分离区域,降低动能消耗,进而提高了车辆燃油经济性,另外,无需改变原车辆驾驶室的白车身,仅针对A柱外饰板改进设计,故能应用于不同车型,且制造成本低,设计周期短,同时也使维修更加方便。
