Vehicle air dam structure, and methods of use and manufacture thereof
Some embodiments are directed to a crossbar structure for use with a vehicle having a front bumper assembly, the crossbar structure being configured to extend across an opening in the front bumper assembly. The crossbar structure can include a hollow bar defining a front face and a rear face, the hollow bar being configured to extend across the opening. The crossbar structure can also include ribs extending between opposing interior surfaces of the hollow bar, the ribs being formed in a zig-zag pattern along a direction of elongation of the hollow bar and exposed from the rear face thereof.
1. A crossbar structure for use with a vehicle having a front bumper assembly, the crossbar structure being configured to extend across an opening in the front bumper assembly, the crossbar structure comprising:
a hollow bar having a front face, a rear face, and opposing first and second inner surfaces, the hollow bar being configured to extend across the opening; and
ribs extending between the opposing first and second inner surfaces of the hollow bar, the ribs being angled along a direction of elongation of the hollow bar and exposed from the rear face thereof,
wherein the ribs comprise a first rib extending from the first inner surface of the hollow bar to the second inner surface of the hollow bar at a first angle relative to the direction of elongation of the hollow bar and a second rib extending from the second inner surface of the hollow bar to the first inner surface of the hollow bar at a second angle relative to the direction of elongation of the hollow bar, the first angle being different than the second angle.
2. The crossbar structure according to claim 1 , wherein the ribs are configured to extend in an alternating manner so as to form a zig-zag pattern within the hollow bar.
3. The crossbar structure according to claim 2 , wherein the ribs are configured to form triangular spaces therebetween within the hollow bar.
4. The crossbar structure according to claim 1 , wherein the ribs are configured to terminate between opposing ends of the hollow bar.
5. The crossbar structure according to claim 1 , wherein the ribs are configured to be flush with the rear face of the hollow bar.
6. The crossbar structure according to claim 1 , wherein the ribs are configured to extend rearward beyond the rear face of the hollow bar.
7. The crossbar structure according to claim 6 , wherein portions of the ribs extending beyond the rear face of the hollow bar are configured as approximately triangular extensions.
8. The crossbar structure according to claim 7 , wherein the portions of the ribs extend toward alternating sides of the rear face.
9. The crossbar structure according to claim 1 , wherein the ribs are configured with sufficient thickness so as to impede deformation of the front face of the hollow bar from airflow passing across the hollow bar when the vehicle is moving in a forward direction of travel.
10. The crossbar structure according to claim 9 , wherein the ribs are configured to disrupt airflow passing across the hollow bar so as to impede whistle-like sounds thereof.
11. A front bumper assembly of a vehicle, the front bumper assembly comprising:
at least one opening configured as an exterior intake to accept passage of airflow therethrough; and
at least one crossbar structure extending across the opening, the at least one crossbar structure including:
a hollow bar having a front face, a rear face, and opposing first and second inner surfaces, the hollow bar being configured to extend across the opening; and
ribs extending between the opposing first and second inner surfaces of the hollow bar, the ribs being angled along a direction of elongation of the hollow bar and exposed from the rear face thereof,
wherein the ribs comprise a first rib extending from the first inner surface of the hollow bar to the second inner surface of the hollow bar at a first angle relative to the direction of elongation of the hollow bar and a second rib extending from the second inner surface of the hollow bar to the first inner surface of the hollow bar at a second angle relative to the direction of elongation of the hollow bar, the first angle being different than the second angle.
12. The front bumper assembly according to claim 11 , wherein the ribs are configured to extend in an alternating manner so as to form a zig-zag pattern within the hollow bar.
13. The front bumper assembly according to claim 12 , wherein the ribs are configured to form triangular spaces therebetween within the hollow bar.
14. The front bumper assembly according to claim 11 , wherein the ribs are configured to terminate between opposing ends of the hollow bar.
15. The front bumper assembly according to claim 11 , wherein the ribs are configured to be flush with the rear face of the hollow bar.
16. The front bumper assembly according to claim 11 , wherein the ribs are configured to extend rearward beyond the rear face of the hollow bar.
17. The front bumper assembly according to claim 16 , wherein portions of the ribs extending beyond the rear face of the hollow bar are configured as approximately triangular extensions.
18. The front bumper assembly according to claim 17 , wherein the portions of the ribs extend toward alternating sides of the rear face.
19. The front bumper assembly according to claim 11 , wherein the ribs are configured with sufficient thickness so as to impede deformation of the front face of the hollow bar from airflow passing across the hollow bar so as to impede whistle-like sounds thereof when the vehicle is moving in a forward direction of travel.
20. A method of forming a crossbar structure for use with a vehicle having a front bumper assembly, the crossbar structure being configured to extend across an opening in the front bumper assembly, the method comprising:
providing a hollow bar having a front face, a rear face, and opposing first and second inner surfaces;
configuring the hollow bar to extend across the opening; and
forming ribs to extend between the opposing first and second inner surfaces of the hollow bar so as to be angled along a direction of elongation of the hollow bar and exposed from the rear face thereof,
wherein the ribs comprise a first rib extending from the first inner surface of the hollow bar to the second inner surface of the hollow bar at a first angle relative to the direction of elongation of the hollow bar and a second rib extending from the second inner surface of the hollow bar to the first inner surface of the hollow bar at a second angle relative to the direction of elongation of the hollow bar, the first angle being different than the second angle.
