Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a headlamp unit for an automobile in which the front surface of the headlamp unit is flush with the front surface of the hood.

[Problems that the invention attempts to solve with conventional technology]

FIG. 6 shows this type of headlamp unit 1, in which the front surface of the lens 1a is flush with the front surface of the hood 2 above, thereby achieving a unique design effect. Therefore, when the lens 1a is running, a large amount of the airflow generated from below the front surface of the lens 1a along the front surface of the hood 2 enters the narrow part of the gap 3 between the upper end of the headlamp unit 1 and the tip of the hood 2, and the flow velocity decreases. There was a problem in that the increase in wind noise caused wind noise.

Therefore, in the past, a protector was attached to the gap 3 to close the gap 3.

In view of this point, it is an object of the present invention to suppress the generation of wind noise generated in the gap between the headlamp unit and the hood in the headlamp unit itself as described at the beginning.

[Means for solving problems]

In order to achieve this object, the present invention provides a hood front 2a and a headlamp unit front 5 along the upper front edge of the headlamp unit, that is, a lens only or optionally a peripheral lamp. A protrusion 5a is formed that protrudes from the general surface 6 defined by the front surface including the container.

[Effect]

Hood 2 from below the front of the headlamp unit.
The airflow generated toward the protrusion 5a is disturbed as shown in the figure, and the amount of air entering the gap 3 is reduced, thereby suppressing the generation of wind noise.

[Example of idea]

In FIG. 2, the front surfaces of the headlamp unit 10 and the radiator grille 20 form the same plane along the front surface of the hood 2 that descends toward the front. As shown in FIG. 3, the radiator grill 20 is composed of a flat horizontally long panel 21 and a frame-shaped radiator grill main body 22 into which the panel is fitted. Front of hood 2, panel 2
1 and the lower frame 22b of the radiator grill body 22 define the general surface 15 of the front of the vehicle, and the tip 22a of the upper frame is connected to the panel 21.
By being located at the upper end of the front surface, a protrusion for preventing wind noise is formed. As shown in FIG. 4, the headlamp unit 10 has a flat front lens 12 attached to a lamp 11 defining a general surface 15. A molding 13 serving as a wind noise prevention protrusion having the same protrusion width and thickness as the upper frame tip 22a of the radiator grill body 22 is adhered to the front upper end of the lens 12.

Note that the present invention can be applied to prevent wind noise only in the headlamp portion even when the radiator grill is in the form of a grid. The protrusion can also be formed on the lens itself or by protruding the lamp frame around the lens. FIG. 5 shows another embodiment in which the radiator grill also serves as a wind noise prevention function of the headlamp unit. That is, mounting holes 31 for headlamps are formed at both ends of the radiator grille 30, a flat panel 32 is fitted in the center, and a protrusion 33 for preventing wind noise is formed at the upper end of the front surface of both mounting holes. It extends to 31.

[Effects of the invention] As described above, according to the invention, turbulent flow occurs near the gap at the leading edge of the hood, and the headlamp unit itself can eliminate wind noise without separately installing a protector to the gap to prevent wind noise. It is possible to prevent the noise, that is, the whistling sound.
