Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a radiator grill for an automobile, in which the front surface of the radiator grille is formed flat and continues to form the same plane as the front surface of the hood.

[Problems that conventional technology and ideas try to solve]

FIG. 5 shows a radiator grille of this kind without a lattice-like decoration over the front side. That is,
In some cases, a flat horizontally long panel 2 having a horizontally long ventilation hole at the bottom is fitted into the frame-shaped radiator grill body 1 so as to form the same plane, and is further fitted along the front shape of the hood 3 above. They are on the same surface. Therefore, while driving, airflow generated along the hood 3 from below the front surfaces of the radiator grills 1 and 2 flows between the upper end of the radiator grill body 1 and the hood 3.
There was a problem in that a large amount of wind entered the gap 4 between the tips of the windshield and the flow velocity increased, causing wind noise.

Therefore, in the past, a protector was attached to the gap 4 to close the gap 4.

In view of this point, it is an object of the present invention to prevent the radiator grill itself from generating wind noise generated in the gap with the hood in the type of radiator grill mentioned at the beginning.

[Means for solving problems]

In order to achieve this objective, the present invention has been developed for an automobile in which the front surface of a flat radiator grille 8 is continuous so as to form the same surface with a gap 4 in the front hood 3a, as shown in FIG. In the radiator grille, the general surface 9 is formed by protruding forward from the flat general surface 9 on the front surface of the radiator grille 8.
The radiator grille 8 is characterized in that a strip-like protrusion 8a is extended in the vehicle width direction at the upper end of the front surface of the radiator grille 8, and the airflow coming up from below hits the radiator grille 8.

[Effect]

The airflow rising from below toward the hood 3 along the general surface 9 of the radiator grille 8 flows through the protrusion 8a.
As a result, the amount of air entering the gap 4 is reduced, thereby suppressing the generation of wind noise.

[Example of idea]

In FIGS. 2 and 3, a radiator grill 10
is a flat oblong panel 1 equipped with ventilation holes 11a.
1, and a frame-shaped radiator grill body 12 into which this panel is fitted. food 3
front panel 11 and radiator grill body 1
The lower frame 12b of No. 2 defines the general surface 13 of the front of the vehicle, and the tip portion 12c of the upper frame 12a is located at the upper end of the front surface of the panel 11 to form a strip-like protrusion for preventing wind noise. It forms a part.

Note that such wind noise also occurs when the flat front surface of the headlamp continues below the hood 3. FIG. 4 shows another embodiment of the headlamp which has both the molding function and the wind noise prevention function. That is, in the same figure, the radiator grill 20
Mounting holes 21 for headlamps are formed at both ends, a flat panel 22 is fitted in the center, and a strip-like protrusion 23 for wind noise prevention extends from the upper end of the front surface.

[Effect of idea]

As described above, according to the present invention, the strip-like protrusion at the upper end of the front surface of the radiator grill causes airflow that attempts to enter the gap along the front surface of the grill to become turbulent, and a protector for preventing wind noise is separately installed in the gap. The radiator grill itself can prevent wind noise, or whistling noise, without having to install it.

Claims (1)

[Scope of Claim for Utility Model Registration] In an automobile radiator grill in which the flat front surface of the radiator grille is continuous so as to form the same surface with a gap in the front surface of the hood, from the flat general surface of the front surface of the radiator grille to the front. A radiator grille characterized in that a strip-like protrusion portion, which protrudes and is exposed to airflow rising from below along the general surface, extends in the vehicle width direction at an upper end portion of the front surface of the radiator grille.
