Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a front pillar structure for a vehicle, and particularly to an improved front pillar structure for a vehicle that can reduce wind noise caused by water cutting.

BACKGROUND ART In order to prevent rainwater from the front windshield from splashing onto the side windshields during driving in rainy weather, the front pillars of normal vehicles are provided with drains, which allow rainwater to drain quickly. is being carried out.

However, this water drainer has a problem in that it is a major cause of wind noise during high-speed driving.

In the past, various measures were taken to prevent this kind of wind noise, such as lowering the height of the drainer or changing its shape. However, there was a drawback that a sufficient effect of reducing wind noise could not be obtained, and the draining performance was deteriorated.

Purpose of the invention The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide an improved front pillar structure for a vehicle that reduces the generation of wind noise without reducing the drainage effect. .

Structure of the Invention In order to achieve the above object, the present invention provides a vehicle front pillar structure in which a drainer is fixed to the front pillar that holds the windshield fixedly. It is characterized by a fixed rectifier plate.

Embodiments Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a schematic diagram of a vehicle to which the present invention is applied, in which a drainer 14 is fixed to a front pillar 12 that holds a front windshield 10 fixedly. The vehicle in this embodiment is a fully concealed wiper vehicle, and the lower part of the front windshield 10 enters into the engine hood 16, thereby preventing the wiper device from being exposed to the outside in the stored state, as is well known. do not have.

According to various experiments conducted by the inventor of the present invention, the wind noise generated from the front pillar 12, especially the water cutter 14, is actually caused by the water cutter 14 itself and the turbulent flow below it, that is, the part connected to the engine hood 16. It was confirmed that the latter accounted for a relatively large proportion. Therefore, according to the present invention, it is proposed to prevent turbulent flow at the lower part of the front pillar 12, and according to such a front pillar structure, a fully concealed wiper as shown in FIG. It was confirmed that wind noise caused by turbulent flow in the gap between the lower part of the front pillar 12 and the engine hood 16 in the vehicle was significantly reduced.

FIG. 2 shows an enlarged view of section A in FIG.

As is clear from FIG. 2, a characteristic feature of the present invention is that a substantially triangular rectifying plate 18 is provided near the bottom of the front pillar 12, and this rectifying plate 18 is connected to the front windshield 10. It is fixed in close contact with the surface of
Furthermore, this current plate is fixedly arranged so as to close the rainwater receiving groove provided in the drainer. In the fully concealed wiper-equipped vehicle of this embodiment, the rectifying plate 18 is almost entirely fixed in a position housed within the engine hood 16.

FIG. 3 shows a cross section of the drainer 14 shown in FIG. 2, and as is clear from the figure, the drainer 14 is designed to prevent rainwater from entering between the windshield 10 and the front pillar 12. It extends closely to this front pillar 12. This drainer 14 has a groove for receiving rainwater collected from the surface of the front windshield 10, and the groove guides the rainwater to the lower part. FIG. 4 shows a cross section of the rectifying plate 18 in the present invention, which is closely fixed to the front windshield 10 and the front pillar 12.
is held by. Therefore, at the lower part of the front pillar 12, the rainwater collected by the drainer 14 shown in FIG. It is understood that near the lower part of the vehicle 12, the current plate 18 prevents the generation of turbulence that occurs during high-speed travel.

Particularly, in a vehicle equipped with a fully concealed wiper as in the embodiment, turbulence is significant due to the empty space created between the engine hood 16, the front pillar 12, and the drainer 14. However, according to the present invention, the rectification is By arranging the plate 18 in this area, the occurrence of turbulence is reduced, and on this basis it is possible to significantly reduce wind noise.

FIG. 5 shows a sound pressure characteristic diagram of wind noise. Compared to the conventional characteristic shown by the solid line, the sound pressure level is significantly reduced by providing the rectifying plate 18 of the present invention as shown by the broken line. It is understood that this is possible.

Effects of the invention As explained above, according to the present invention, it is possible to reduce wind noise without changing the drainage structure by installing a current plate, and as a result, the conventional drainage effect can be maintained as is. It has the advantage of being able to
