Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a front body structure of an automobile.
[0002]
[Prior art]
Generally, in a front body structure of an automobile, a radiator is provided at the rear of a shroud panel as shown in JP-A-3-2844481 and JP-A-8-301144, and with the radiator, The engine arranged at the rear is to be cooled via engine cooling water.
[0003]
By the way, since the charging efficiency increases as the intake air temperature decreases, it is preferable that the intake port of the engine is disposed on the front side of the vehicle body to make it difficult to take in heat.
[0004]
[Problems to be solved by the invention]
However, when the intake port of the engine is disposed on the front side of the vehicle body, the intake port is positioned close to the radiator, and the heat radiated from the radiator easily enters the engine together with the intake air. For this reason, when the intake port of the engine is arranged on the front side of the vehicle body, it is difficult to improve the charging efficiency.
[0005]
The present invention has been made in view of the above circumstances, and its technical problem is that even when the engine intake port is disposed on the front side of the vehicle body, it is difficult to easily take heat from the intake port. An object of the present invention is to provide a front vehicle body structure for a vehicle.
[0006]
[Means for Solving the Problems]
In order to achieve the above technical problem, the present invention (invention of claim 1)
In the front body structure of an automobile in which a radiator is disposed behind the shroud panel and an engine is disposed behind the radiator,
In the vicinity of the radiator, an intake port of the engine is disposed,
A partition member is provided on the shroud panel ,
The partition member cooperates with the shroud panel to form a chamber that opens only upward to the outside,
The air inlet is housed in the chamber, and the air inlet is isolated from the outside by the bottom and peripheral wall of the chamber;
The partition member and the shroud panel are integrally formed of resin . A preferred embodiment of the invention of claim 1 is as described in claim 2 .
[0007]
【The invention's effect】
According to the first aspect of the present invention, since the partition member is provided on the shroud panel so as to isolate the radiator and the intake port, the engine intake port is arranged on the front side of the vehicle body. Even in this case, the partition member can suppress the heat from the radiator from flowing into the intake port, and even when the intake port is arranged on the front side of the vehicle body, heat can be easily taken from the intake port. It can be difficult.
[0008]
In addition, the partition member cooperates with the shroud panel to form a chamber that is open only at the top, and the intake port is housed in the chamber. In addition to being able to make it difficult, the partition member can be effectively used as a reinforcing member for the shroud panel, and rainwater or the like blown from the lower side can be reliably prevented from entering the intake port.
Furthermore, since the shroud panel and the partition member are made of resin and the partition member and the shroud panel are integrally formed, it can be manufactured very easily by integral molding of the resin.
[0009]
According to the invention described in claim 2 , since the lamp is supported on the shroud panel and the partition member is provided at a position corresponding to the support portion of the lamp, the rigidity of the lamp support portion is improved. Can be increased.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a front vehicle body structure according to the embodiment. The front vehicle body structure 1 has an apron rain 3 and a front frame at the left and right ends of the shroud panel 2 around the shroud panel 2. It is formed by joining 4 respectively.
[0012]
The shroud panel 2 is molded with resin, the central portion 5 of the shroud panel 2 is substantially flat, and the left and right side portions 6 of the shroud panel 2 in the vehicle width direction extend outward in the vehicle width direction. It is inclined to extend rearward. Lamp openings 7 are formed in the left and right side portions 6 of the shroud panel 2 in the vehicle width direction, and a large central opening 8 is formed in the center portion of the shroud panel 2.
[0013]
A headlamp 9 is mounted in each lamp opening 7 of the shroud panel 2. Each headlamp 9 extends slightly longer in the vehicle width direction according to each lamp opening 7, and the front end portion of the headlamp 9 projects slightly forward of the vehicle body from the shroud panel 2. The rear end portion of 9 projects slightly rearward from the shroud panel 2.
[0014]
A radiator 10 is disposed on the rear side of the vehicle body of the shroud panel 2 so as to face the central opening 8, and an engine 11 is disposed on the rear side of the vehicle body of the radiator 10. As is known, cooling water from the engine 11 is guided to the radiator 10. The engine 11 cooling water in the radiator 10 is cooled by the running wind and the cooling fan 12, and the cooled engine is cooled. 11 Cooling water is to be returned to the engine 11 (water jacket).
[0015]
The engine 11 includes an intake pipe 13 for introducing intake air. In the present embodiment, the intake pipe 13 is curved to ensure the intake pipe length and extends to the left in the vehicle width direction. An air cleaner 14 is interposed in the intake pipe 13 in the middle, and the intake port (tip portion) 15 of the intake pipe 13 is located in the rear region of the left headlamp 9 with the opening facing upward. It has become.
[0016]
The shroud panel 2 is provided with a plate-like partition member 16. The partition member 16 is also formed of the same resin as the shroud panel 2, and the partition member 16 and the shroud panel 2 are integrally formed with the same resin. The partition member 16 is formed so as to extend rearward from the shroud panel 2 between the radiator 10 and the intake port 15. The partition member 16 isolates the intake port 15 and the radiator 10 from the radiator 10. The direct inflow of heat is regulated.
[0017]
Therefore, in this embodiment, even when the intake port 15 is arranged in the vicinity of the radiator 10, the radiator 15 can be easily connected to the radiator 15 based on the plate-shaped partition member 16 integrally formed with the shroud panel 2. The heat from 10 can be made difficult to enter. Moreover, the plate-like partition member 16 functions as a reinforcing member (rib) at the corresponding position of the left headlamp. In the present embodiment, the left side portion 6 (headlamp support) of the shroud panel 2 in the vehicle width direction. Part) can be improved.
[0018]
FIG. 4 shows another embodiment. In this embodiment, the same components as those of the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0019]
In another embodiment shown in FIG. 4, the partition member 16 is to cooperate with the shroud panel 2 to form the chamber 17. The chamber 17 is defined on the left side in the vehicle width direction of the shroud panel 2 except for an upper portion that becomes an opening, and the intake port 15 of the intake pipe 13 faces the chamber 17 from below. Yes.
[0020]
Therefore, in this other embodiment, the radiator 10 is excellent in shielding against heat, and it is possible to make it difficult to take in heat from the intake port 15.
Further, at the corresponding position of the left headlamp 9, the partition member 16 is disposed so as to be spanned over the shroud panel 2, and can effectively function as a reinforcing member. The rigidity of the portion 6 (head lamp support portion) can be further improved.
Furthermore, the air inlet 15 is housed in the chamber 17 whose bottom (lower part) is covered with the outside, so that rainwater or the like blown from the lower side can be reliably prevented from entering the air inlet 15. Although the embodiment has been described above, it goes without saying that the present invention may be applied to the right side portion (headlamp support portion) in the vehicle width direction of the shroud panel 2.
[0021]
It is to be noted that the object of the present invention is not limited to what is explicitly described, but also implicitly includes providing what is substantially preferable or corresponding to what is described as an advantage.
