The grille panel includes a first structure and a second structure forming a flow guide passage, the first structure includes a separation panel 1 and a flow convergence panel 2, and the second structure includes a buffer panel 3. A flow guide channel is formed by the arrangement of the first structure and the second structure, so that the air flow is convenient to circulate. The separation panel 1 is a curved surface structure connected with the flow collection panel 2, and guides the airflow from the flow collection panel 2 to be far away from the flow guide channel when the running speed of the automobile is high, and the pressure at the opening is lower due to the injection effect, so that the air inflow is reduced. The cushion panel 3 is for adjusting the direction of the airflow flowing toward the cushion panel 3 to the direction in which the cushion panel 3 guides the airflow. When the speed of a vehicle is faster, the air input of the grating is reduced through the ejection effect of the airflow of the flow gathering panel 2, and the wind resistance is reduced.

For example, a distance of 30 mm may be selected for use near the headlights on both sides of the frontal area of the vehicle body. The included angle between the plane where the connection part of the flow collecting panel 2 and the separation panel 1 is located and the plane where the buffer panel 3 is located is 45-75 degrees.
