The invention discloses an automobile windshield drainage channel based on airflow blockage prevention, and relates to the technical field of automobile parts. The automobile windshield drainage channel comprises a first arc-shaped cavity main body with an L-shaped cross section and a second arc-shaped cavity main body with an L-shaped cross section, the horizontal section of the first arc-shapedcavity main body communicates with the inclined end of the second arc-shaped cavity main body to form a drainage cavity; the first arc-shaped cavity main body and the second arc-shaped cavity main body define an arc-shaped drainage channel; a plurality of air inlets are uniformly formed in the arc-shaped side surface of the horizontal section of the second arc-shaped cavity main body; a pluralityof first water outlets are uniformly formed in the bottom surface of the arc-shaped drainage channel; a plurality of second water outlets are uniformly formed in the bottom surface of the horizontal section of the first arc-shaped cavity body. When an automobile travels, high-speed air flow flows into the drainage cavity from the air inlet in the arc-shaped side face, small leaves and light chippings blocked by the first drainage opening are blown out by the air flow in the drainage cavity, and convenient cleaning is achieved.

    本发明公开了基于气流防阻塞的汽车挡风玻璃排水槽,涉及汽车零件技术领域。本发明包括横截面为L形的第一弧形腔主体以及横截面为L形的第二弧形腔主体;第一弧形腔主体的水平段与第二弧形腔主体的倾斜端连通形成排水腔;第一弧形腔主体与第二弧形腔主体围成弧形排水道;第二弧形腔主体的水平段的弧形侧面均布开设若干进风口;弧形排水道底面均布开设若干第一排水口;第一弧形腔主体水平段底面均布开设若干第二排水口。本发明当汽车行走时,高速风流从弧形侧面的进风口流进排水腔内,排水腔内的风流将第一排水口堵塞的小树叶以及轻质碎屑吹出,实现便捷清理。
