Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle body structure, and more particularly to a vehicle body front structure having an engine intake structure.

Conventional technology The front structure of the conventional automobile body was developed in 1983.
There is one as shown in Publication No. 50860. However, it is desired to reduce the amount of protrusion at the front for reasons such as design reasons, and if a headlamp escape embossment 1a is provided at the front end of the hood rigid panel 1 as shown in the first figure, which protrudes toward the outside of the vehicle, A headlamp (not shown) can be placed at the rear, but the arrangement of the air introduction system (not shown) to the engine becomes difficult.

Therefore, an air intake hole 3 connected to the engine (not shown) is bored in a portion near the front of the hood rigid panel 1, and an air intake hole 3 is formed on the outside of the vehicle. It is conceivable to install an air duct 4 that opens at the rear of the hood rigid panel 1 so that an air introduction system that cannot be located inside the engine room can be arranged. Moreover, 2 is a hood rigid reinforcement welded and fixed to the upper outer surface of the hood rigid panel 1, and a crushing beat 2a is formed in the front part of this hood rigid reinforcement.

Problem to be Solved by the Invention However, even with such a structure, when a frontal collision of a car occurs, the portion of the hood lid reinforcement 2 where the crushing bead 2a would normally be provided is crushed in order from the front side. However, depending on the size of the air intake holes 3 made in the hood rigid panel 2, the strength of this part of the hood rigid panel 2 may be reduced, and the collapse beat 2a may not function adequately. Furthermore, the number of structural parts of the vehicle body may increase due to the provision of the air duct 4 for reducing intake noise.

An object of the present invention is to obtain a structure in which the crushing beat of a hood rigid reinforcement can function satisfactorily even when air intake holes are formed in the hood rigid panel without causing the above-mentioned problems. It is in.

Means for Solving the Problems In order to achieve this object, the present invention forms a headlamp relief emboss on the front part of the hood rigid panel that protrudes toward the outside of the vehicle, and also forms a head lamp relief emboss on the front part of the hood rigid panel. The present invention proposes that the cylindrical space surrounded by the cylindrical space be used as an air duct, and that this cylindrical space be opened in a side open space formed above the headlamp relief embossing.

Embodiment Hereinafter, details of an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

In FIGS. 2 to 4, the same structural parts as in FIG. 1 are designated by the same reference numerals.

According to the present invention, a headlamp escape embossment 1a is provided in the front part of the hood lid panel 1 where the rear of the headlamp (not shown) is located, and the headlamp escape embossment 1a projects toward the outside of the vehicle. A space B is formed. In addition, hood ridge panel 1
A cylindrical space A surrounded by the hood reinforcement 2 and the hood reinforcement 2 and extending in the front-rear direction is used as an air duct for taking in air from an engine (not shown).

That is, according to this embodiment, the front end 2b of the hood rigid reinforcement 2 is connected to the hood rigid panel 1.
It opens forward in a side open space B above the headlamp escape embossing 1a, and outside air is introduced into the cylindrical space A from this open end. And air intake hole 3 in this embodiment
A is opened on the hood rigid panel 1 near the rear of the cylindrical space A, that is, on the surface forming the engine room, and outside air is taken into the engine intake system through this air intake opening 3A. In the illustrated embodiment, a plurality of small holes 4 are formed in the crushing bead 2a of the hood lid rain hose 2, and the water is taken into the cylindrical space A through these small holes 4. The intake noise within the cylindrical space A is reduced due to the interference of outside air.

Since the above embodiment has the above structure,
There is no need to use a dedicated air duct like in the past, which reduces manufacturing costs, and the muddy water splashed up from the road surface can be removed by the headlamp embossing 1.
Due to the presence of a, there is no direct flow into the cylindrical space A. Since the air intake hole 3A in the present invention is opened at a position corresponding to the hood rigid rain hose 2, the air intake hole 3A in the present invention is opened at a position corresponding to the hood rigid rain hose 2, so that by opening in a portion where there is only one hood rigid panel as in the conventional case, When the crushing bead 2a is provided on the hood lid reinforcement 2 without becoming extremely weak, the function of the crushing bead 2a can be fully exhibited. Furthermore, by providing the small holes 4 in the bead 2a as in this embodiment, the bead portion can be more reliably crushed in the event of a vehicle collision.

Although the above embodiment shows an example in which the hood lid rain hose is provided on the outside of the hood lid panel, the hood lid rain hose may also be provided on the inside, that is, on the engine room side, in which case the air intake The access openings may be formed on three sides of the hood lid rain hose on the engine room side, that is, on the top, bottom, and sides.

Effects of the Invention In the end, according to the present invention, a headlamp relief emboss is formed at the front part of the hood lid that protrudes to the outside of the vehicle, and the engine intake air is provided using the space surrounded by the hood lid panel and the hood lid reinforcement. Since the intake duct opens in the side open space above the headlamp relief emboss, there is no risk of muddy water or the like entering the intake duct.
Furthermore, the manufacturing cost is low and weight can be reduced.
