Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front structure of an automobile in which a pair of left and right overlyzers are attached to a front bumper so as to project forward from the vehicle body.

[0002]

2. Description of the Related Art In automobiles, a bumper portion at the front of the vehicle body is provided with optional decoration parts such as fog lights and decorative parts in a substantially hat shape in front view called kangaroo bumpers. Although attachment is sometimes performed, when these optional components are attached, the front portion of the vehicle body protrudes forward by the length of the optional component, which increases the overall length of the vehicle body. Therefore, as disclosed in, for example, Japanese Utility Model Laid-Open No. 63-161059, there is a case in which an over- lyzer which projects forward to the left and right of the front portion of the vehicle body is equipped. This overlay is a member mounted on the front bumper or the like so as to project to the front of the vehicle body with the both sides of the above-mentioned optional parts sandwiched between them. This eliminates the change in the total length of the vehicle body due to the presence or absence of the optional parts as described above.

[0003]

By the way, in the case of equipping the above-described over riser, it is desired to make the over riser as small as possible and improve the workability of attaching the over riser. Further, since this overhanger is angularly projected from the front bumper toward the front of the vehicle body as described above, when the overloader is equipped, when the load acts from the front side of the vehicle body, the load is in the engine room. There is a possibility that it may be difficult to be transmitted to the disposed front side frame.

Therefore, the present invention makes it possible to reduce the size of the overlay and improve the workability of installation, and
An object of the present invention is to provide a front structure of an automobile capable of favorably transmitting a load from the front of a vehicle body to a front side frame.

[0005]

[Means for Solving the Problems] That is, claim 1 of the present invention.
The invention described in (hereinafter, referred to as the first invention) includes a pair of left and right front side frames extending in the front-rear direction of the vehicle body at positions below the front part of the vehicle body on the left and right sides, and a front bumper is provided with a pair of left and right overlayers. In the front structure of an automobile that is mounted so as to project forward, the above-mentioned over- lyzer is offset near the tip of the front side frame in the vehicle width direction and above the front side frame in the height direction. It is characterized in that it is provided at each position, and a weakened portion which can be compressed and deformed by a load from the front of the vehicle body is formed in each of these over- lyzers.

Further, in the invention described in claim 2 (hereinafter referred to as the second invention), the fragile portion is an air introduction opening formed in the over- lyzer, and the fragile portion is provided at a position immediately behind and behind the front bumper. It is characterized in that it is provided with a cooling device to which the air introduced from the air introduction opening is blown.

[0007]

According to the first aspect of the invention described above, the overrise is arranged near the front end of the front side frame in the vehicle width direction, and the fragile portion which can be compressed and deformed by the load from the front of the vehicle is formed in the overrise. Has been done,
When a load is applied from the front of the vehicle body, the load can be reliably transmitted to the front side frame by the above-mentioned compressive deformation.

Further, the fact that the over- lyzer is arranged near the front end of the front side frame in the vehicle width direction is different from the case where it is arranged outside the front side frame and attached to the curved portions on both sides of the front bumper. It is possible to reduce the amount of overhang protrusion for obtaining a predetermined vehicle body length.

Further, since the over- lyzer is arranged above the front side frame in the height direction, the mounting position of the over- lyzer is increased and the mounting workability is improved.

Further, according to the second aspect of the invention, the air introduced from the air introduction opening formed in the overlyzer blows against the cooling device, so that the cooling efficiency of the cooling device can be improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, left and right front side frames 2 and 2 extending in the front-rear direction of the vehicle body are provided at both left and right positions in an engine room provided in a front portion of an automobile 1.
The engine 3 is mounted vertically between the front side frames 2 and 2, and the engine oil cooler 4 is provided outside the one front side frame 2 and near the front end of the engine room. An intercooler 6 is supported and provided by a support plate 5 as shown in FIG. 3, and is provided outside the other front side frame 2 and at a position near the front end of the engine room by a similar support structure. A front panel 7 is provided in front of the intercooler 6 and the engine oil cooler 4, and a front bumper 8 is attached to the front panel 7.

Further, an air intake port composed of an upper grill 9 and an under grill 10 is opened in the front panel 7 and the front bumper 8 at a position corresponding to between the left and right front side frames 2 and 2.
Running wind is taken into the engine room from these grills 9 and 10, and running wind is applied to the above-mentioned engine oil cooler 4 and intercooler 6 at the curved portions 8A and 8A at both ends of the front bumper 8 in the vehicle width direction. Air intake holes 11 to 11 are provided so as to be blown against.

Further, a pair of left and right overrisers 12 having a predetermined protrusion amount are attached to the front surface of the front bumper 8. As is apparent from FIGS. 2 to 5, the overrise 12 has a box shape, an air introduction opening 13 is formed at the front end surface thereof, and a flange portion 14 is formed at the peripheral portion of the rear end thereof. Flange part 1
4 a clip part 1 behind at least the upper and lower edges
5, 15 are integrally provided. On the other hand, front bumper 8
A mounting opening 16 is provided in the overlyzer mounting portion on the side, and an engaging hole 17 is formed in an edge portion of the mounting opening 16, and the clip portion 15 of the overlay 12 is fitted in the engaging hole 17. By fitting, the edge portion is sandwiched and fixed by the flange portion 14 and the clip portion 15 of the over riser 12.

In this case, the mounting positions of the respective overizers 12 and 12 are the central positions avoiding the bumper curved portion 8A of the front bumper 8 in which the air intake hole 11 described above is provided, and the vehicle width direction. At the position near the tip of the front side frame 2 (see FIG. 3),
In the height direction, the front side frame 2 is attached at a position (see FIG. 4) offset above the tip of the front side frame 2.

Further, in the front bumper 8, the opening 16 for mounting the over riser 12 is provided with the over riser 1
The running wind introduced from the air introduction opening 13 at the tip of the flow path 2 flows toward the front of the engine oil cooler 4 in the engine oil cooler 4 side, and flows in the intercooler 6 side in the intercooler 6 side. Is provided with a guide plate 18 (see FIG. 3) that flows in the front direction.

In such a structure, the overrises 12, 12 are projected to the front of the vehicle body with respect to the front bumper 8, and the length of the vehicle body is determined with the tip of the overrise 12 as the standard front end position of the entire vehicle body length. Therefore, as shown in FIGS. 1 and 2, even if an optional component X, which is called a kangaroo bumper, is mounted between the over bumpers 12, 12 of the front bumper 8, the entire length of the vehicle body may increase. Disappear.

By the way, the above-mentioned overizers 12, 12 are
Are curved portions 8A, 8 at both ends of the front bumper 8 in the vehicle width direction.
It is installed at a position avoiding A. Therefore, the oversize 12 is downsized. That is, assuming that the over riser 12 is attached to the above-mentioned curved portion 8A, if an attempt is made to secure a predetermined amount of protrusion between the front bumper 8 and the tip of the over riser, as shown in FIG. Since the front-rear length L must be increased, the size of the overlayer is increased. However, if it is attached to the vehicle body center line side while avoiding the curved portion 8A, the front-rear length of the over- lyzer 12 can be shortened.

The overlay 12 is mounted at a position higher than the front side frame 2. Therefore, the ground clearance up to the over- lyzer 12 becomes high,
Workability at the time of attaching the over- lyzer 12 to the front pumper 8 is improved, and it is advantageous for a vehicle type such as a recreational vehicle (RV vehicle) in which a large approach angle θ between the wheel 19 and the over- lyzer 12 is desired. .

Further, since the air introducing opening 13 is provided at the tip end surface of the over- lyzer 12, the traveling wind is introduced into the inside of the bumper as the vehicle travels. The guide plate 18 formed on the front bumper 8 changes the direction of the engine oil cooler 4 and the intercooler 6 and sends the oil. Therefore, the engine oil cooler 4 and the intercooler 6 are blown with not only the traveling wind from the air intake holes 11 to 11 but also the traveling wind introduced from the overlyer 12. Cooling efficiency is increased.

By the way, when the overrise 12 is projected to the front of the front bumper 8, when the load is applied from the front of the vehicle body, the rigidity of the overrise 12 causes the above-mentioned load on the front side frames 2 and 2. Is less likely to be transmitted. However, the above-mentioned over riser 12 is provided with the air introduction opening 13, and this opening 13 is a fragile portion that reduces the rigidity of the over riser 12. Therefore, when a load is applied from the front of the vehicle body, the over- lyzer 12 is easily compressed and deformed. For this reason, when the above-mentioned loader acts from the front of the vehicle body in combination with the fact that the over- lyzer 12 is provided near the tip of the front side frame 2 in the vehicle body width direction,
Due to the compression deformation of the over riser 12, the load can be surely transmitted to the front side frame 2.

The fragile portion formed in the over riser 12 is not limited to the structure shown in FIG. 5, and as shown in FIG. 6, a plurality of air introducing holes 20-2 are formed on the peripheral surface of the over riser.
0 may be provided.

[0023]

As is apparent from the above description, according to the present invention, the over- lyzer is arranged near the front end of the front side frame in the vehicle width direction, and the over- lyzer is loaded by the load from the front of the vehicle. Since the fragile portion which can be compressed and deformed is formed, when a load acts from the front of the vehicle body, the load can be surely transmitted to the front side frame by the above-mentioned compressive deformation.

Further, the fact that the overrider is arranged in the vicinity of the front end of the front side frame makes it possible to provide a predetermined distance, as compared with the case where it is arranged outside the front side frame and attached to the curved portions on both sides of the front bumper. It is possible to reduce the amount of protrusion of the over riser in order to gain the entire length of the vehicle body, and it is possible to downsize the over riser.

In the height direction,
Since it is arranged above the front side frame, the mounting position of the over- lyzer becomes higher and the mounting workability is improved.

Further, according to the present invention, the air introduced from the air introduction hole forming the fragile portion can be blown against the cooling devices to enhance the cooling efficiency of these cooling devices.
