Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production, in particular to an automobile front bumper air curtain and a manufacturing method thereof. Background Art

[0002] The air curtains, with openings on either side of the front bumper, not only create a visual impact but also significantly enhance aerodynamic performance. The function of the front bumper air curtains is to guide the airflow during driving, directing it through the air curtain's intakes, through channels on the inside of the bumper, and out to the outside of the wheels. This diversion softens the airflow around the wheels, reducing drag and thus reducing the vehicle's air resistance. Typically, front bumper air curtains are positioned separately from the headlights, without a matching relationship between the air curtains and the headlights, resulting in a relatively monotonous air curtain design. However, with increasingly aggressive styling, automakers are now placing the headlights within the air curtains, surrounding them and matching their perimeter. While this novel and unique design presents technical challenges due to the complex structure of the headlights, the lamp body occupies a large space, while also accommodating the air curtain's integration with the front bumper. Summary of the Invention
