Abstract

The present invention addresses the problem of, during traveling in rain, preventing rain from adhering to a light collection material (1) serving as a wind protection for a vehicle body, and reducing the number of times of wiping of wipers (4) to thereby continuously provide good visibility, and during high-speed traveling, generating appropriate downforce. The present invention has a configuration in which a rain spoiler (2) having approximately the same length as the width of a light collection material (1) serving as a wind protection for a vehicle body is provided on a hood (3) immediately in front of a lower end frame of the light collection material (1) with gaps from wipers (4) with respect to the hood (3) so as to be obliquely rearward and upward inclined at an angle approximately parallel to the light collection material (1) or larger than the inclination angle of the light collection material (1) and protrude to an appropriate height, thereby generating appropriate downforce, and deflecting traveling wind (7) in a direction above the roof of the light collection material (1) so that rain is prevented from adhering to the surface of the light collection material (1) during traveling in rain.

Description

Rain spoiler

The present invention relates to a rain spoiler that protects against rain and snow (hereinafter referred to as rain) adhering to a daylighting material serving as a windshield of a vehicle body during running during rain, and generates downforce during running.

Conventionally, rain adhered to a daylighting material that serves as a windshield for a vehicle body during rainy weather is wiped off with a wiper. The operation of the wiper wipes rain by a circular reciprocating motion in which the wiper blade moves up and down or left and right with an axis provided on the window frame as a fulcrum. Since the number of times the wiper wipes rain is directly proportional to the amount of rain, the wiper blade crosses in front of the driver's eyes when the number of wiper wipes is large. In recent years, it has been possible to blow away rain by water-repellent processing of daylighting materials, but it is ineffective against snow, mist, frost, insect hits, and mud splashes. Further, when the vehicle body travels at a high speed even on a straight road, the road surface followability of the tire is lowered. However, when an appropriate downforce occurs, the steering stability is improved by pressing the tire against the ground.
