  In the cowl louver opening 36, it is formed along the vehicle width direction and is extended substantially in the vehicle lower side (more strictly, the vehicle rear oblique lower side, the direction in which air flows in (see FIG. 2)). A plurality of vehicle width direction wall portions 38 (lateral louver portions) are provided, and a plurality of front and rear direction wall portions 40 (vertical louver portions) that are formed along the vehicle front-rear direction and extend substantially downward with respect to the vehicle are provided. It has been.

  The vehicle width direction wall portion 38 has both a function of adjusting the air direction of air flowing from the cowl louver opening 36 and a function of returning water to the water flowing from the cowl louver opening 36. Here, the height of the vehicle width direction wall 38 shown in FIG. 2 (the amount of extension to the vehicle lower side) is the height position and size of the duct opening 26B, the opening position of the cowl louver opening 36, and the vehicle front and rear. It is determined by the size of the direction and the positional relationship between the duct opening 26B and the cowl louver opening 36 in the vehicle longitudinal direction.

  More specifically, all the imaginary straight lines that pass through the cowl louver opening 36 and pass through the cowl louver opening 36 toward the lower end position A of the duct opening 26B through the non-contacting position on the vehicle front side of the cowl louver opening 36 (see FIG. Among them, the representative line of the imaginary straight line is indicated by reference numerals L1, L2, and L3), and is extended to a position where at least one of the vehicle width direction wall portions 38 intersects. In addition, the virtual straight lines L1, L2, and L3 in the figure correspond to the line containing the hose car wash water, and the virtual straight line L1 is a virtual straight line with the smallest inclination angle. Further, the symbol B at the rear end portion 14A of the hood 14 prevents water from going straight into the cowl louver opening 36 and the duct opening 26B on the vehicle front side of the cowl louver opening 36. This virtual point is drawn when a virtual straight line is drawn in the straight direction of water passing through the cowl louver opening 36 from the front side of the cowl louver opening 36 toward the lower end position A of the duct opening 26B. The point used to determine the minimum inclination angle of the straight line when viewed from the side of the vehicle is shown, and the virtual straight line L1 passes slightly above the hard point B above the vehicle.

  In the present embodiment, the lower end position of the vehicle width direction wall portion 38 disposed on the vehicle rear side of the virtual straight line L1 having the smallest inclination angle among all the virtual straight lines is set as follows. That is, referring to FIG. 2 with reference to a partially enlarged view as appropriate, the vehicle front side of the vehicle width direction wall portion 38 on the vehicle rear side of the virtual straight line L1 having the smallest inclination angle among the virtual straight lines is the frontmost. The lower end position of the vehicle width direction wall 38 (38A) located on the side (third from the right in the drawing) is set to a height position that intersects the virtual straight line L1. Further, the vehicle width direction wall portion 38 (38B) located adjacent to the vehicle rear side with respect to the vehicle width direction wall portion 38 (38A) (second in the drawing from the right) is adjacent to the vehicle front side. Is set to a height position that intersects an imaginary straight line L2 connecting the upper end of the vehicle width direction wall portion 38 (A) and the lower end position A of the duct opening 26B. Similarly, the vehicle width direction wall 38 (38C) located adjacent to the vehicle rear side with respect to the vehicle width direction wall 38 (38B) (rightmost in the drawing) is adjacent to the vehicle front side. The vehicle width direction wall portion 38 (38B) is positioned at a height position that intersects a virtual straight line L3 that connects the lower end position A of the duct opening 26B. Note that the vehicle width direction wall portion 38 (38C) formed on the most rear side of the vehicle is set so as to intersect with any of the virtual straight lines having an inclination angle larger than the virtual straight line L3 among all the virtual straight lines. .

  Moreover, the lower end position of the front-rear direction wall part 40 formed along the vehicle front-rear direction is a height position connecting the lower ends of the vehicle width direction wall part 38, and the lower end shape of the front-rear direction wall part 40 is the vehicle width direction. The wall 38 is connected to the lower end position.

  As described above, the inside of the cowl louver opening 36 has a shape in which the cowl louver opening 36 is divided into a plurality of pieces and a plurality of small openings are formed, that is, a mesh shape (lattice shape) that can prevent entry of dead leaves and the like. ing. In the cowl louver 30, the vehicle width direction wall portion 38 and the front-rear direction wall portion 40 function as water return ribs, and water that prevents water from entering the duct opening 26B when water is discharged from the vehicle front side or the vehicle side side. It has a cowl louver structure that can prevent (or suppress) entry.

  The cowl louver 30 is integrally formed by injection molding as described above, and the vehicle width direction wall portion 38 and the front-rear direction wall portion 40 extend (extend) in a predetermined molding direction (extraction direction). ) For this reason, it is not necessary to make the parts of the vehicle width direction wall part 38 and the front-rear direction wall part 40 as separate parts, and the cowl louver 30 can be made into one part, so that productivity is good.

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  A duct opening 26B for introducing air of the cowl body 22 is formed in the rear wall 26A, and a cowl louver opening 36 for introducing air in the cowl louver 30 is substantially diagonally forward and forward of the rear wall 26A of the cowl body 22. Since it is formed on the upper wall portion 34 </ b> A that is formed so as to face the air, the air from the outside of the vehicle does not wrap around in an S shape when viewed from the side of the vehicle, and the duct opening of the cowl main body 22 from within the cowl louver opening 36 of the cowl louver 30. It flows into the part 26B side (see arrow C direction).

  If it supplements, in order to suppress permeation of water, in contrast structure which makes the air from the outside of the vehicle wrap around in an S shape in a side view of the vehicle, the inflow resistance of the air is increased and the pressure loss rate is increased. On the other hand, in the cowl structure according to the present embodiment, the inflow resistance of air is small and the intake load is suppressed.

  Here, in the cowl structure according to the present embodiment, the duct opening 26B of the cowl main body 22 and the cowl louver opening 36 of the cowl louver 30 overlap in the vehicle width direction position (see FIG. 3), so that air from the outside of the vehicle Hardly flows in the vehicle width direction, and efficiently flows from the cowl louver opening 36 of the cowl louver 30 toward the duct opening 26B of the cowl body 22 (see the direction of arrow C). For this reason, the intake resistance during the operation of the air conditioner can be reduced, and the intake efficiency is improved.

  Further, as another effect associated with the setting of the position of the duct opening 26B in the vehicle width direction, there is almost no flow (wraparound) of the intake air in the vehicle width direction, so that the intake air hardly affects the heat from the cowl body 22. There is also an effect of not receiving. That is, the cowl lower panel 28 of the cowl body 22 is affected by the heat of the engine room 42 from directly below, so that when the intake air passes over the cowl lower panel 28, the heat of the engine room 42 side through the cowl body 22. Although (engine heat) is transmitted to the intake air, in the case of this embodiment, the intake air is hardly affected by the engine heat because there is almost no flow (wraparound) of the intake air in the vehicle width direction. As a result, for example, compared with a comparison structure in which the vehicle width direction position between the duct opening (26B) of the cowl body (22) and the cowl louver opening (36) of the cowl louver (30) is set on the opposite side in the vehicle width direction. Since the intake air temperature does not rise, the load (loss) due to the operation of the air conditioner for cooling the intake air can be suppressed and the fuel consumption can be improved as compared with the comparative structure. In addition, even when traveling without using an air conditioner, there is a merit that the warm wind from the cowl space 20A does not enter the cabin.

  Further, in the cowl structure according to the present embodiment, the duct of the cowl body 22 passes through the cowl louver opening 36 through the non-contact position on the vehicle body side (hard point B) on the vehicle front side of the cowl louver opening 36 of the cowl louver 30. At least one of the vehicle width direction walls 38 formed in the cowl louver opening 36 of the cowl louver 30 with respect to all virtual straight lines (see L1, L2, L3) directed to the lower end position A of the opening 26B. For example, even when water goes straight into the cowl louver opening 36 of the cowl louver 30 at the time of washing the hose or the like, the duct opening of the cowl main body 22 is formed by the vehicle width direction wall 38 even when the water goes straight into the cowl louver opening 36. The straight movement of water to the inside of 26B is blocked. The water dropped upon hitting the vehicle width direction wall portion 38 flows along the drainage flow path of the cowl lower panel 28 and is drained.

  Further, in the cowl louver opening 36 of the cowl louver 30, a plurality of front-rear direction wall portions 40 that are formed along the vehicle front-rear direction and extend substantially to the vehicle lower side are provided. Since the lower end shape is a shape that connects the lower end position of the vehicle width direction wall portion 38, for example, when the hose is washed, the cowl louver opening of the cowl louver 30 is discharged obliquely with respect to the vehicle longitudinal direction or from the side of the vehicle. Even if water goes straight into 36, the straight wall of water in the duct opening 26 </ b> B inside the cowl body 22 is more effectively blocked by the front-rear direction wall 40. Here, since the front-rear direction wall portion 40 is formed along the vehicle front-rear direction, there is almost no resistance when air from the outside flows in.

  As described above, according to the cowl structure according to the present embodiment, the inflow resistance of air is suppressed while preventing or suppressing the ingress of water into the duct opening 26B for introducing air on the cowl body 22 side. Can do.

  Moreover, since the cowl louver 30 of this embodiment can be integrally formed by injection molding, the number of parts can be suppressed and the cost can be reduced. Supplementally, for example, in the structure as described in Patent Document 1 (Japanese Utility Model Publication No. 3-5508), a Z-shaped portion is formed as a separate body in a side sectional view (including the inflow port) for convenience of molding. In addition, the cowl louver 30 needs to be attached to the cowl louver body.

(Supplementary explanation of the embodiment)
In the above embodiment, the duct opening 26B serving as the first opening and the cowl louver opening 36 serving as the second opening are completely overlapped with each other in the vehicle width direction. However, when the positional relationship between the first opening and the second opening cannot be completely overlapped due to, for example, design restrictions, the vehicle width direction of the first opening The position where the position of the first opening overlaps with the position of the second opening in the vehicle width direction, or the same position in the vehicle width direction of the vehicle width direction of the first opening and the position of the second opening in the vehicle width direction However, other positional relationships such as a setting that does not overlap may be used. Here, if the vehicle width direction position of the first opening and the vehicle width direction position of the second opening are set at least on the same side in the vehicle width direction, for example, different sides in the vehicle width direction (i.e., The intake efficiency is better than when the first opening and the second opening are set on the right side in the vehicle width direction and the other on the left side in the vehicle width direction.

  In the above embodiment, the cowl louver opening 36 as the second opening is formed on the substantially horizontal upper wall 34A (substantially horizontal plane) of the cowl louver 30. In the case where the second opening is formed in a substantially circular arc shape having a small diameter compared to the above-described embodiment in which the vehicle upper side is radially inward in a side cross-sectional view, the second opening is The upper wall portion may be formed on an inclined surface portion that is inclined obliquely upward to the rear side of the vehicle (as an example, about 45 °), and the formation portion of the second opening is not necessarily limited to a substantially horizontal surface portion.

  Moreover, in the said embodiment, the vehicle width direction wall part 38 and the front-back direction wall part 40 are provided in the cowl louver opening part 36 as a 2nd opening part, The inside of the cowl louver opening part 36 is made into mesh shape, Although such a configuration is preferable, for example, by providing only the vehicle width direction wall portion (38) in the second opening portion (the cowl louver opening portion (36)), the second opening portion is divided and the vehicle width direction is divided. Alternatively, a structure in which a small slit-like opening is formed may be used.

  Furthermore, in the above-described embodiment, a plurality of vehicle width direction wall portions 38 are provided in the cowl louver opening portion 36 as the second opening portion, and such a configuration is preferable. All that are provided in the two openings and that pass through the non-contact position on the vehicle body side on the vehicle front side of the second opening and pass through the second opening toward the lower end of the first opening It is good also as a structure extended to the position where the lower end part of the said vehicle width direction wall part cross | intersects with respect to this virtual straight line.

  Furthermore, in the above embodiment, a plurality of front and rear direction wall portions 40 are provided in the cowl louver opening 36 as the second opening, and such a configuration is preferable. It is good also as a structure by which only one is provided in an opening part, and the lower end shape is made into the shape which connects the lower end position of a vehicle width direction wall part.

  In the above embodiment, the imaginary straight line L1 having the smallest inclination angle passes slightly above the vehicle upper side of the hard point B of the rear end portion 14A of the hood 14. For example, the rear end of the hood (14) When the portion (14A) is covered with a covering member, the covering member is a hard point, and the virtual straight line (L1) having the smallest inclination angle is slightly above the vehicle on the covering point. You will pass by the side. As another example, for example, the front end part (34B) of the main body part (34) of the cowl louver (30) protrudes to the upper side of the vehicle to the same height as the rear end part (14A) of the hood (14). In this case, the front end portion (34B) of the main body portion (34) of the cowl louver (30) serves as a water-filled hard point, and the virtual straight line (L1) having the smallest inclination angle is defined by the cowl louver (30). The hard point at the front end (34B) of the main body (34) passes slightly above the vehicle.
