It extends.

  As shown in FIG. 1, the cowl body 14 including the cowl lower 16, the cowl inner 22, and the cowl outer 24 is open on the vehicle body upper side and is covered with a cowl louver 28. The cowl louver 28 is disposed along the vehicle width direction. An outside air introduction hole 28A is formed on one side (right side in the figure) of the cowl louver 28 in the vehicle width direction, and a hot air discharge hole 28B is formed on the other side (left side in the figure) of the cowl louver 28 in the vehicle width direction. Yes.

  As shown in FIG. 2, the cowl louver 28 has an end on the vehicle rear side coupled to the front edge 10 </ b> A of the windshield 10, and an end on the vehicle front side on an end of the cowl lower 16 on the vehicle front side. It is connected. As described above, the cowl 12 including the cowl body 14 and the cowl louver 28 forms a cowl space 25 as an air passage extending along the vehicle width direction.

  Inside the cowl space 25 of the cowl 12 (in the cross section), a pair of shielding plates 40 are provided along the longitudinal direction of the vehicle body as partition walls that partition the cowl space 25 in the vehicle width direction. As shown in FIG. 1, the pair of left and right shielding plates 40 are disposed adjacent to both sides in the vehicle width direction with respect to the outside air introduction hole 22D of the cowl inner 22 and the outside air introduction hole 28A of the cowl louver 28, respectively. It is a member for preventing or suppressing hot air (hot air) generated from an engine (not shown). Further, as shown in FIG. 1, a sealing material 42 is provided at the peripheral portion of the shielding plate 40, and a water passage valve 48 is attached to the lower end portion of the shielding plate 40.

  As shown in FIG. 3 schematically showing the shielding plate 40 in front view of the vehicle, the sealing material 42 (shown in cross section in the drawing) of the shielding plate 40 is in close contact with the inner peripheral surface of the cowl space 25. . A cowl space 25 formed between the cowl body 14 and the cowl louver 28 is partitioned by a shielding plate 40 into a first cowl space 25A for introducing outside air and a second cowl space 25B. The hot air introduced into the second cowl space 25B from the engine room 18 shown in FIG. 1 enters the outside air introduction hole 22D provided on the first cowl space 25A side (as a result, unillustrated outside air connected to the outside air introduction hole 22D). Intrusion into the introduction duct). A wiper (not shown) is arranged in the second cowl space 25B on the left side in the drawing, and the shielding plate 40 also has a role of preventing water from being applied to the wiper during car washing.

  The shielding plate 40 includes a resin plate-like body (corrugated board-like member) as an anisotropic material. 4 shows a resin plate 38 as an anisotropic material constituting the shielding plate 40 (see FIG. 1). FIG. 4A is a side view of the plate 38, FIG. 4 (B) is a front view of the plate-like body 38. As shown in FIG. 4A, the plate-like body 38 includes a pair of flat plate portions 38A arranged opposite to each other, and a plurality of connections that connect the flat plate portions 38A to each other in the thickness direction of the plate-like body 38. Part 38B, and is formed in a ladder shape as viewed in the direction of FIG. As shown in FIG. 4B, the connecting portion 38B extends in one direction (see the arrow C direction in FIG. 4B) along the surface direction of the flat plate portion 38A. In FIG. 4B, the connecting portion 38B omits the plate thickness and indicates the extending direction with a dotted line (the same applies to FIG. 2 and FIG. 5 of the second embodiment described later).

  In other words, the shielding plate 40 shown in FIG. 2 has a rigidity in one direction along the partition surface 40A (see the arrow C direction) in a direction perpendicular to the one direction along the partition surface 40A (see the arrow D direction). It is made of a higher anisotropic material. Further, the shielding plate 40 has one direction (refer to the arrow C direction) orthogonal to the direction (refer to the arrow F direction) toward the rear lower side of the vehicle when viewed in the direction facing the partition surface 40A (in a broad sense, it intersects). )). In other words, the shielding plate 40 is set so that the direction in which the rigidity is set low (see the arrow D direction) is directed to the incident direction of the head impactor 50 in the pedestrian protection test (see the arrow F direction).

  Near the lower portion of the front end of the shielding plate 40, a first fixing portion 40B is formed. One attachment portion 34A of the attachment bracket 34 is attached to the first fixing portion 40B by an attachment clip 44A inserted in the vehicle width direction. The other mounting portion 34B of the mounting bracket 34 is fastened to the cowl lower 16 by a screw (indicated by a fastening line 46A in the drawing). The mounting bracket 34 has a plurality of reinforcing ribs 34C.

  On the other hand, a second fixing portion 40 </ b> C is formed at a substantially central portion of the rear end portion of the shielding plate 40 in the vehicle body vertical direction. One attachment portion 36A of the attachment bracket 36 is attached to the second fixing portion 40C by an attachment clip 44B inserted in the vehicle width direction. The other mounting portion 36B of the mounting bracket 36 is fastened to the cowl inner 22 by a screw (indicated by a fastening line 46B in the drawing).

  Here, the first fixing portion 40B and the second fixing portion 40C of the shielding plate 40 are out of the range of the intrusion stroke S assumed in advance of the head impactor 50 in order to suppress the reaction force by the shielding plate 40 at the time of collision. The position is set to a position below the virtual line when a virtual line perpendicular to the penetration direction is drawn from the position where the head impactor 50 arrives at the penetration stroke S. In the present embodiment, the first fixed portion 40B and the second fixed portion 40C have a virtual line perpendicular to the penetration direction drawn from the position where the head impactor 50 reaches with the penetration stroke S, rather than the virtual line. Although it is located on the lower side, it is set to a relatively high position on the lower side from the viewpoint of the retaining property of the shielding plate 40.

  The fastening direction by the mounting clips 44A and 44B is a direction in which a load is applied to the shielding plate 40 when the shielding plate 40 is assembled. However, the bending rigidity of the shielding plate 40 is high. It is also adapted to the direction of receiving wind pressure from hot air. Further, the fastening direction of the screws 46A and 46B is set to a direction generally along one direction (in the direction of the arrow C) set with high rigidity in the shielding plate 40.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  In the present embodiment, as shown in FIG. 1, the cowl space 25 provided in the front portion of the vehicle is divided into a first cowl space 25 </ b> A and a second cowl space 25 </ b> B by the shielding plate 40 attached to the cowl body 14. It is partitioned. For this reason, for example, hot air introduced from the engine room 18 into the second cowl space 25B on the left side in the figure is prevented from entering the outside air introduction hole 22D provided on the first cowl space 25A side.

  Here, as shown in FIG. 2, the shielding plate 40 attached to the cowl 12 has a rigidity in one direction (refer to the arrow C direction) along the partition surface 40A orthogonal to the one direction along the partition surface 40A. It is formed of an anisotropic material having a rigidity higher than the rigidity in the direction (see the arrow D direction), and the one above the direction (see the arrow F direction) toward the lower rear of the vehicle when viewed in the direction facing the partition surface 40A. The direction (see arrow C direction) is set to be orthogonal. For this reason, for example, when the head impactor 50 collides with the cowl louver 28 from the obliquely forward front side of the vehicle (being struck) and a load directed downward in the rear of the vehicle acts on the shielding plate 40, the shielding plate 40 is They are easily deformed so as to be bent along a broken line along the one direction (see the direction of arrow C).

  Thereby, the reaction force with respect to the head impactor 50 is suppressed, and the stroke of the head impactor 50 can also be secured (ensuring pedestrian protection performance). At this time, as shown in FIG. 3, the shielding plate 40 can be deformed so as to be bent to the left and right sides in the vehicle width direction according to the collision direction or the like of the head impactor 50 in the vehicle front view. In FIG. 3, a state where the shielding plate 40 is deformed so as to be bent to the left and right sides in the vehicle width direction is indicated by a two-dot chain line as an example. Incidentally, the shielding plate 40 that can be bent on both sides can be said to be a member that can be installed if there is at least a space for falling on one side.

  On the other hand, when a load directed downward in the rear of the vehicle does not act, the shielding plate 40 attached to the cowl 12 is not easily deformed and is held at the partition position. For this reason, as described above, since the hot air is stably suppressed from entering the outside air introduction hole 22D from the engine room 18 shown in FIG. 1, the air conditioning performance is improved, and as a result, the fuel consumption rate (fuel efficiency) ) Can also be improved.

  Further, in this embodiment, the anisotropic material forming the shielding plate 40 is a resin plate 38 shown in FIG. 4, and one pair of flat plate portions 38 </ b> A arranged to face each other is one. Since it is connected by a plurality of connecting portions 38B extending along the direction, rigidity anisotropy is easily ensured. Further, since the air layer 38C can be formed between the flat plate portions 38A, the heat conduction is suppressed by the shielding plate 40. Thereby, for example, the heat of the second cowl space 25B on the left side in the drawing in which hot air is introduced from the engine room 18 shown in FIG. 1 is not easily transmitted to the first cowl space 25A side.

  As described above, according to the vehicle front structure according to the present embodiment, when a load greater than a predetermined value is applied from the diagonally upper front side of the vehicle while maintaining the posture of the shielding plate 40 during normal use. The resistance force by the shielding plate 40 can be suppressed.

  Here, a supplementary explanation will be made while comparing with the comparison structure. For example, in the comparison structure of the resin molded product in which the weak portion is formed to bend at a predetermined portion when a load of a predetermined value or more is applied from the diagonally upper front side of the vehicle, The weight is likely to increase, a mold is required, and a polygonal line processing is also required, resulting in high processing costs. On the other hand, in the present embodiment, the use of the thin plate-like body 38 can efficiently achieve rigidity, so that the weight can be reduced. When the plate-like body 38 is used as a raw material, only the punching die is used. Because it can be formed by, processing costs can be reduced.

  Further, for example, in another contrasting structure in which the shielding plate is assembled to the cowl via the clip so that it tilts in only one direction when a load of a predetermined value or more is applied from the diagonally upper front side of the vehicle, the one direction and The resistance increases when tilting to the opposite side, and when the shield plate is not sufficiently engaged with the clip, the shield plate may tilt when assembled. On the other hand, in this embodiment, the shielding plate 40 is fixed to the cowl 12 with a structure that can be bent and deformed on either the left or right side when a load of a predetermined value or more is applied from the diagonally upper front side of the vehicle. There is no problem like the other contrast structure.

[Second Embodiment]
Next, a vehicle front structure according to a second embodiment of the present invention will be described with reference to FIGS. Note that components similar to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  FIG. 5 shows a vehicle front structure according to the second embodiment of the present invention in a longitudinal sectional view corresponding to an enlarged sectional view taken along line 5-5 of FIG. Further, FIG. 6 shows the shielding plate 60 of FIG. 5 in a state where the fender panel 54 is seen through in a schematic side view in a vehicle side view.

The fender panel 54 hangs from the upper end portion of the outer wall portion 54A at an outer wall portion 54A that covers the upper side of a front wheel (not shown) and forms the side surface (design surface) of the front portion of the vehicle, and the parting portion 56 with the hood 30. And an inner wall portion 54B bent substantially downward with respect to the vehicle body. Further, the inner wall portion 54B of the fender panel 54 includes an inner vertical wall portion 154B that is suspended from the upper end portion of the outer wall portion 54A substantially downward in the vehicle body, and a vehicle width direction inner side (from the lower end portion of the inner vertical wall portion 154B). And a horizontal flange portion 254B extending substantially horizontally to the engine room 18 side).

  An apron upper member 58 as an inner member is disposed on the vehicle body lower side of the horizontal flange portion 254B of the fender panel 54 and on the inner side in the vehicle width direction of the outer wall portion 54A of the fender panel 54. The apron upper member 58 is disposed with the front-rear direction of the vehicle body as a longitudinal direction, and has a closed cross-sectional structure. Further, a cowl louver 28 as an inner member is disposed on the inner side in the vehicle width direction at the upper portion of the outer wall portion 54A of the fender panel 54.

  The fender panel 54, the cowl louver 28, and the apron upper member 58 constitute a passage forming portion 52. The passage forming portion 52 is provided in the front portion of the vehicle and forms an air passage 55 that communicates with the vehicle longitudinal direction. Yes.

  In the passage forming portion 52, shielding plates 60 and 62 as partition walls are vertically attached and arranged in the air passage 55 (in the cross section) along the vehicle width direction. Thereby, the shielding plates 60 and 62 partition the air passage 55 in the vehicle front-rear direction. In addition, since the shape of the air passage 55 is somewhat complicated, the shielding plates 60 and 62 partition the air passage 55 with two upper and lower members in consideration of formability. Also good.

  The shielding plates 60 and 62 are formed of the resin plate 38 shown in FIG. 4 as in the first embodiment. As shown in FIG. 5, the shielding plates 60 and 62 are viewed in the direction facing the partition surfaces 60A and 62A. A direction with high rigidity (refer to the direction of arrow C) is orthogonal (crossed in a broad sense) to a direction directed downward to the rear of the vehicle (refer to the direction of arrow F, which is the downward direction in the direction view of FIG. 5). It is set to be.

  A fixing portion 60B is formed near the lower portion of the inner end portion of the shielding plate 60 in the vehicle width direction. One attachment portion 64A of the attachment bracket 64 is attached to the fixed portion 60B by an attachment clip 66A inserted in the vehicle front-rear direction. The other mounting portion 64B of the mounting bracket 64 is fastened to the upper part of the apron upper member 58 by screws (indicated by a fastening line 68A in the drawing).

  A fixing portion 62B is formed at the inner end of the shielding plate 62 in the vehicle width direction. One attachment portion 70A of the attachment bracket 70 is attached to the fixed portion 62B by an attachment clip 66B inserted in the vehicle front-rear direction. The other mounting portion 70B of the mounting bracket 70 is fastened to the lower portion of the apron upper member 58 by screws (indicated by a fastening line 68B in the drawing).

  In addition, although illustration is abbreviate | omitted, it is preferable that the lower part of the vehicle width direction outer side edge part of the shielding board 60 and the vehicle width direction outer side edge part of the shielding board 62 are fixed to the fender panel 54 side.

  Here, the fixing portion 60B of the shielding plate 60 is positioned outside the range of the intrusion stroke S assumed in advance of the head impactor 50 in order to suppress the reaction force by the shielding plate 60 at the time of a collision (the head at the invasion stroke S). Is set to a position below the position where the partial impactor 50 reaches.

  The fastening direction by the mounting clips 66A and 66B is a direction in which a load acts on the shielding plates 60 and 62 when the shielding plates 60 and 62 are assembled, but the bending rigidity of the shielding plates 60 and 62 is high. In addition, the shielding plates 60 and 62 are also adapted to receive wind pressure from hot air from the engine side. Further, the fastening direction of the screws 68A and 68B is set to a direction that substantially follows one direction (arrow C direction) in which the rigidity is set high in the shielding plates 60 and 62.

  According to the present embodiment, as in the first embodiment, the shielding plates 60 and 62 attached to the passage forming portion 52 are easily deformed during normal use when a load directed downward to the rear of the vehicle does not act. The initial posture is maintained at the partition position. In addition, when the head impactor 50 collides with the fender panel 54 and the hood 30 in the vicinity of the parting portion 56 from the obliquely forward front side of the vehicle, a load directed toward the rear lower side of the vehicle acts on the shielding plate 60. 60 is easily deformed so as to bend toward the vehicle rear side along a fold line along the one direction (see the arrow C direction). 6, the shielding plate 60 can be deformed not only to be bent toward the vehicle rear side but also to be bent toward the vehicle front side (the shielding plate of FIG. 5). 62 is the same).
