Motor vehicle with retractable headlamps and headlamp washers - has miniature spoilers deployable in-front of each headlamp to localise formation of eddies in slipstream

摘要

The headlamps (1) are recessed into the bodywork at a distance (a) behind small and similarly retractable aerodynamic spoilers (3) positioned and dimensioned so that the small eddies are confined to the region in front of the headlamps (1), ensuring substantially streamline flow (7) over the bonnet (2). The spoilers (3) may be triangular with the apex directed forward, and may incorporate nozzles for washing the headlamp glasses in the deployed position. ADVANTAGE - Acoustic noise which could cause annoyance to driver and passengers, and vibrations of e.g. rear view mirrors (8) and radio antennas, are avoided or reduced.
