Description

  The present invention relates to a vehicle body front structure for a vehicle in which a cowl louver that covers a front cowl from above is provided, and air in an interior space of the front cowl is sucked by a blower operation toward a passenger compartment inside the vehicle body. Is.

  Conventionally, there is a vehicle body front structure of the vehicle described in Patent Document 1 below. According to this publication, the front body structure of a vehicle extends in the width direction of the vehicle body, and a front cowl in which each section in the longitudinal direction forms a U shape, and extends in the width direction of the vehicle body to A cowl louver covering from above, an air suction port formed in a part of the longitudinal direction of the rear plate of the front cowl, and sucking the air in the interior space of the front cowl toward the compartment inside the vehicle body by the operation of the blower And a water shielding plate that protrudes from the cowl louver toward the interior space of the front cowl and is disposed between a vent hole and an air inlet of the cowl louver.

  In the above configuration, when the blower is operated and air is sucked into the air suction port, the air outside the vehicle body passes through the vent hole of the cowl louver according to the negative pressure generated at the air suction port, and the inner space of the front cowl. In addition, the air is sucked from the interior space of the front cowl to the passenger compartment through the air suction port. Thus, the air sucked into the passenger compartment is then supplied to the passenger compartment and used for ventilation and air conditioning of the passenger compartment.

  On the other hand, when it rains or is washed, water droplets from the outside of the vehicle body may rush into the interior space of the front cowl through the cowl louver vent. In this case, there is a possibility that the water droplets will vigorously collide with the inner surface of the front cowl and bounce off, being sucked together with the air sucked into the air suction port and heading toward the passenger compartment. However, the water droplets are prevented from being sucked into the air suction port by the above-described water shielding plate, so that entry into the passenger compartment is prevented.

JP 2004-58722 A

  By the way, for the ventilation and air conditioning of the passenger compartment, the amount of intake air at the air intake port due to the operation of the blower is frequently changed. The pressure increases. At this time, as described above, if the water droplets jumped into the front cowl vigorously and rebounded vigorously on the inner surface of the front cowl, the water droplets were described above regardless of the presence of the water shielding plate. Inhalation is caused by a large negative pressure at the air intake port, and as a result, there is a risk that water droplets enter the passenger compartment.

  Therefore, in order to ensure that a sufficiently large amount of intake air can be secured at the air intake port, a separate water shielding plate is provided in order to more reliably prevent inhalation of water droplets into the air intake port. Alternatively, it is conceivable that the air flow passage in the inner space of the front cowl from the vent hole of the cowl louver to the air inlet has a more complicated labyrinth structure.

  However, with the above configuration, there is a risk that the pressure loss of the air flowing in the inner space of the front cowl will increase unnecessarily, and the amount of intake air to the passenger compartment side may unnecessarily decrease. May become complicated and the productivity may be reduced.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to provide a cowl louver that covers the front cowl from above, and the air in the inner space of the front cowl is located on the side of the passenger compartment inside the vehicle body. In the vehicle body front structure that is sucked by the operation of the blower toward the vehicle, even if water droplets jump into the interior space of the front cowl through the vents of the cowl louver from outside the vehicle body, Intrusion into the cabin side is more reliably prevented, while a sufficient amount of intake air to the cabin side is ensured by the operation of the blower, and this can be achieved with a simple configuration. Is to do.

The invention of claim 1 includes a front cowl 3 that extends in the width direction of the vehicle body 2 and each section in the longitudinal direction forms a U shape, and a cowl louver that extends in the width direction of the vehicle body 2 and covers the front cowl 3 from above. 24 and a part of the rear plate 7 in the longitudinal direction of the front cowl 3, and the air 30 in the inner space 12 of the front cowl 3 is sucked by the operation of the blower 36 toward the vehicle compartment 20 inside the vehicle body 2. An air inlet 35 and a water shielding plate 40 that protrudes from the cowl louver 24 toward the inner space 12 of the front cowl 3 and is disposed between the air hole 31 of the cowl louver 24 and the air inlet 35 are provided. In the vehicle body front structure,
The water shielding plate 40 can be rotated forward and backward A and B with respect to the cowl louver 24, and the water shielding plate 40 faces the air suction port 35 according to the negative pressure of the air suction port 35. It is a vehicle body front part structure characterized in that it is configured to rotate backward B (two-dot chain line in FIG. 1).

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

The present invention includes a front cowl that extends in the width direction of the vehicle body and has a U-shaped cross section in the longitudinal direction, a cowl louver that extends in the width direction of the vehicle body and covers the front cowl from above, and a rear portion of the front cowl. An air inlet that is formed in a part of the plate in the longitudinal direction and sucks air in the interior space of the front cowl toward the passenger compartment inside the vehicle body by the operation of a blower, and from the cowl louver toward the interior space of the front cowl. Vehicle body front part structure provided with a water shielding plate that protrudes and is disposed between the vent hole of the cowl louver and the air suction port,
The water shielding plate can be rotated forward and backward with respect to the cowl louver, and the water shielding plate can be rotated backward toward the air suction port according to the negative pressure of the air suction port. The following effects occur.

  That is, if it rains, water drops from the outside of the vehicle body vigorously jump through the cowl louver vent to the bottom of the inner space of the front cowl, and the water drops vigorously enter the inner surface of the bottom of the inner space of the front cowl. Suppose you hit and bounce back. In this case, the water droplets may enter the air suction port, but the water droplets are prevented from colliding with the water shielding plate and heading toward the air suction port. Therefore, the water droplets are prevented from entering the passenger compartment side through the air suction port.

  On the other hand, when the blower is operated, the amount of intake air at the air intake port due to the operation of the blower is small, and therefore, when the negative pressure of the air intake port is small, the water shielding plate is the air intake port. The air suction port is slightly opened from the original position away from the air inlet, and the air suction port is opened widely. For this reason, there is a risk that the water droplets are sucked together with the intake air into the air intake port that is wide open as described above and enter the passenger compartment.

  However, as described above, the amount of intake air at the air intake port due to the operation of the blower is small and the negative pressure of this air intake port is small, so that the water droplets are sucked into the air intake port by this negative pressure. Is prevented. Therefore, it is possible to prevent water droplets from being sucked into the air suction port and entering the passenger compartment.

  Next, when the amount of intake air at the air intake port due to the operation of the blower is increased, the negative pressure at the air intake port increases, and accordingly, as described above, the water shielding plate sucks air from the original position. It rotates backward toward the mouth side. In this case, the lower side of the water shielding plate farther from the center of rotation has a larger moving dimension during the rearward rotation because of the distance from the rotation center. The lower side is closer to the lower side of the air inlet, and the lower side of the air inlet is narrowed.

  Here, as described above, the water droplets that bounce off and vigorously collide with the inner surface of the bottom of the inner space of the front cowl tend to be sucked together with the sucked air, particularly on the lower side of the air sucking port. However, the lower side of the air intake port is further narrowed by the lower side of the water shielding plate rotated backward as described above, so that the water droplets are sucked into the lower side of the air intake port together with the intake air. Intrusion into the passenger compartment is prevented.

  In addition, when the water shielding plate rotates backward, the upper side of the water shielding plate, which is the side closer to the rotation center, is closer to the rotation center, and the movement dimension during the backward rotation becomes smaller. For this reason, since the upper side of the water shielding plate is prevented from approaching the upper side of the air suction port, the upper side of the air suction port is narrowed by the upper side of the water shielding plate rotating backward. That is suppressed. Therefore, the air in the inner space of the front cowl on the outer side of the water shielding plate in the width direction of the vehicle body is formed between the rear plate of the front cowl and the water shielding plate by the large negative pressure of the air suction port. After passing through the space, the air is smoothly sucked into the upper side of the air suction port. As a result, a sufficient amount of intake air at the air intake port due to the operation of the blower is secured, that is, a sufficient amount of intake air is secured to the passenger compartment side.

  According to the invention described above, the above-described effect that the amount of intake air to the vehicle compartment side is sufficiently ensured while the ingress of water droplets to the vehicle compartment side is prevented is as described above. In order to achieve the above effect, a separate water shielding plate is provided, or the cowl louver is provided to achieve the above effect. It is not necessary to make the air flow passage in the inner space of the front cowl from the air vent to the air suction port more complicated labyrinth structure. Therefore, the above effect can be achieved with a simple configuration.

It is an II sectional view expanded sectional view of the FIG. It is a top view of a vehicle body front part. FIG. 3 is an enlarged sectional view taken along line III-III in FIG. 2.

  The vehicle body front structure of the vehicle according to the present invention is provided with a cowl louver that covers the front cowl from above, so that the air in the inner space of the front cowl is sucked by the operation of the blower toward the compartment inside the vehicle body. In the front structure of the vehicle body, even if water droplets jump into the interior space of the front cowl through the vent hole of the cowl louver from the outside of the vehicle body, the water droplets are more reliably prevented from entering the passenger compartment. On the other hand, in order to achieve the object of ensuring a sufficient amount of intake air to the passenger compartment side by the operation of the blower and achieving this with a simple configuration, the present invention is implemented. The form for carrying out is as follows.

  That is, the vehicle body front structure includes a front cowl that extends in the width direction of the vehicle body and each section in the longitudinal direction forms a U shape, and a cowl louver that extends in the width direction of the vehicle body and covers the front cowl from above. An air inlet that is formed in a part of the rear plate of the front cowl in the longitudinal direction and sucks air in the interior space of the front cowl toward the passenger compartment inside the vehicle body by operation of a blower, and from the cowl louver to the front A water shielding plate is provided that protrudes toward the interior space of the cowl and is disposed between the vent hole of the cowl louver and the air inlet.

The

  A resin cowl louver 24 that extends long in the width direction of the vehicle body 2 and extends in the front-rear direction and covers the front portion of the internal space 12 of the front cowl 3 from above is provided. The front end edge of the cowl louver 24 is supported on the upper surface of the front outward flange 9 of the inner cowl 4. The rear end edge portion of the cowl louver 24 is supported on the upper surface of the front end edge portion of the window panel 18 via a seal member 25, and the front end edge portion of the window panel 18 and the outer cowl 5 The inner cowl 4 is supported by the rear outward flange 10. That is, the cowl louver 24 is supported at both ends at the front and rear edge portions of the inner cowl 4.

  At the front part of the outer cowl 5, a flange 29 having a U-shaped cross section in the longitudinal direction is formed, and the flange 29 is located below the sealing material 25. Then, water droplets W1 that fall into the inner space 12 of the front cowl 3 through the gap between the front edge of the wind panel 18 and the rear edge of the cowl louver 24 and the sealing material 25 are trapped in the flange 29. Then, the water is drained to the outside of the vehicle body 2 through the bottom of the trough 29.

  A front space of the cowl louver 24 is a vehicle body opening 26 that opens the engine room 21 upward, and a hood 27 that closes the vehicle body opening 26 from above is provided. An elastic sealing member 28 is provided which is attached to the front end edge of the cowl louver 24 and seals between the front end edge of the cowl louver 24 and the lower surface of the rear end of the hood 27.

  The front portion of the right side portion of the cowl louver 24 has a large number of passages that allow air 30 outside the vehicle body 2 to be introduced into the front space 12a among the front and rear spaces 12a and 12b in the inner space 12 of the front cowl 3. A pore 31 is formed. The upstream ends of the air holes 31 open upward from the cowl louver 24, and the downstream ends of the air holes 31 are the upper ends of the front spaces 12 a in the internal space 12 of the front cowl 3. It is open.

  In addition, an air conditioner 33 is provided that sucks air 30 in the internal space 12 of the front cowl 3 and supplies the air 30 to the vehicle compartment 20. The air conditioner 33 communicates the internal space 12 of the front cowl 3 with the vehicle compartment 20 and allows the air 30 in the internal space 12 to be introduced into the vehicle compartment 20, and the rear plate of the front cowl 3. 7, an air suction port 35 that allows air 30 in the inner space 12 of the front cowl 3 to be sucked through the air introduction duct 34 toward the vehicle compartment 20, and the front cowl. 3 and a blower 36 capable of sucking air 30 from the inner space 12 toward the vehicle compartment 20 side.

  On the right side portion of the cowl louver 24, a support piece 38 that integrally protrudes downward from a midway portion in the front-rear direction of the cowl louver 24 and extends in the width direction of the vehicle body 2 is provided. Further, the support piece 38 is formed so as to extend downward toward the inner space 12 of the front cowl 3 and to extend in the width direction of the vehicle body 2, and an upper end edge of the support piece 38 is connected to the support piece 38 by a connector 39. A resin water shielding plate 40 to be connected is provided.

  The vent holes 31 of the cowl louver 24, the air inlet 35, and the water shielding plate 40 are arranged at the same position in the width direction of the vehicle body 2, and the water shielding plate 40 is disposed in the inner space 12 of the front cowl 3. The upper side is divided into a front space 12a and a rear space 12b, and is provided so as to partition the vent hole 31 group and the air suction port 35 forward and backward.

  In a cross-sectional view (FIG. 1) of the water shielding plate 40 in a side view of the vehicle body 2, the upper plate 40 a of the water shielding plate 40 extends in the vertical direction and is connected to the support piece 38 by a connector 39. . The midway plate 40b in the vertical direction of the water shielding plate 40 has a bent shape that once extends integrally from the lower edge of the upper plate 40a toward the front and then folded back to the middle. The plate 40b covers the vent holes 31 of the cowl louver 24 from below.

  Further, the lower plate 40c of the water shielding plate 40 extends in a direction inclined rearward and downward from the folded end edge of the midway plate 40b, and the lower end of the lower plate 40c is the bottom plate of the front cowl 3. The free end portion is positioned so as to be slightly away from 8. The air suction port 35 opens toward the front lower side, and the lower ends of the air suction port 35 and the lower plate 40c of the water shielding plate 40 are located at substantially the same height.

  With respect to the cowl louver 24, the water shielding plate 40 can be rotated forward and backward A and B. Specifically, if an external force is applied backward to the lower plate 40c of the water shielding plate 40 and the middle plate 40b of the water shielding plate 40 is bent to oppose its elasticity, it is connected to the cowl louver 24. The lower plate 40c can be rotated backward B from the original position shown by the solid line in FIG. Further, if the external force is removed from the lower plate 40c that has been rotated backward B in this way, the lower plate 40c is rotated forward A to the original position by the elastic restoring force of the intermediate plate 40b. It is supposed to be.

  Here, when the amount of intake air at the air inlet 35 due to the operation of the blower 36 is increased, the negative pressure at the air inlet 35 increases. Then, according to the negative pressure of the air suction port 35, that is, when the negative pressure acts as the external force, the lower plate 40c of the water shielding plate 40 faces the air suction port 35 side as described above. It is supposed to be rotated B from the rear.

  When the blower 36 is operated so as to drive the air conditioner 33, the air 30 is sucked from the inner space 12 of the front cowl 3 through the air suction port 35 toward the vehicle compartment 20 side. In this case, air 30 outside the vehicle body 2 is supplied to the inner space 12 of the front cowl 3 through the vent hole 31 of the cowl louver 24 according to the negative pressure generated in the air suction port 35, while the vehicle compartment 20 The air 30 sucked to the side is then supplied to the passenger compartment 20 and used for ventilation and air conditioning of the passenger compartment 20.

  On the other hand, when it rains or is washed, water flows into the internal space 12 of the front cowl 3 from the outside of the vehicle body 2 through the vent hole 31 of the cowl louver 24, and this water is collected at the bottom of the front cowl 3. The water is drained to the outside of the vehicle body 2.

  In the above configuration, it is assumed that water droplets W2 from the outside of the vehicle body 2 rush into the upper portion of the front space 12a in the internal space 12 of the front cowl 3 from the outside of the vehicle body 2 during rainy weather. In this case, the water droplet W2 is first directed forward so as to separate from the air inlet 35 by passing through the vent hole 31. Further, most of the water droplets W2 that have passed through the vent hole 31 collide with the upper surface of the midway plate 40b of the water shielding plate 40 to weaken the momentum, and are then collected at the bottom of the front cowl 3 2 is drained to the outside. Therefore, the water droplet W2 is prevented from entering the cabin 20 side through the air suction port 35.

  Further, it is assumed that water droplets W3 from the outside of the vehicle body 2 rush into the bottom of the front space 12a in the internal space 12 of the front cowl 3 through the vent hole 31 of the cowl louver 24, and the water droplets W3 It is assumed that the inner space 12 has bounced and bounced vigorously against the inner surface of the bottom. In this case, the water droplet W3 may enter the air suction port 35, but the water droplet W3 is prevented from colliding with the water shielding plate 40 and heading toward the air suction port 35. Thereafter, the front cowl 3 Is drained to the outside of the vehicle body 2. Therefore, the water droplet W3 is prevented from entering the vehicle compartment 20 through the air suction port 35.

  On the other hand, when the air conditioner 33 is driven, the amount of intake air at the air suction port 35 due to the operation of the blower 36 is small. Therefore, when the negative pressure of the air suction port 35 is small, the water shielding plate 40 is The air suction port 35 is greatly opened, with only a slight backward rotation B from the original position (solid line in FIG. 1). For this reason, the water droplet W3 is sucked together with the intake air 30 into the air intake port 35 that is widely opened as described above, and may enter the vehicle compartment 20 side.

  However, as described above, since the amount of intake air at the air inlet 35 due to the operation of the blower 36 is small and the negative pressure of the air inlet 35 is small, the water drop W3 is caused to flow into the air inlet 35 by this negative pressure. Inhalation is prevented. Accordingly, also in this case, the water droplet W3 is prevented from being sucked into the air suction port 35 and entering the vehicle compartment 20 side.

  Next, when the amount of intake air at the air suction port 35 due to the operation of the blower 36 of the air conditioner 33 is increased, the negative pressure at the air suction port 35 becomes larger. Reference numeral 40 denotes a backward rotation B from the original position toward the air suction port 35 (two-dot chain line in FIG. 1). In this case, among the water shielding plates 40, the lower side of the lower plate 40c far from the center of rotation (the middle plate 40b of the water shielding plate 40) is rotated backward by an amount far from the center of rotation. Therefore, the lower side of the lower plate 40c is closer to the lower side of the air suction port 35, and the lower side of the air suction port 35 is narrower. A two-dot chain line in FIG. 1).

  Here, as described above, the water droplet W3 that has rebounded vigorously against the inner surface of the bottom portion of the inner space 12 of the front cowl 3 tends to be sucked together with the suctioned air 30 in the lower part of the air suction port 35. . However, the lower side of the air suction port 35 is further narrowed by the lower side of the lower plate 40c of the water shielding plate 40 rotated backward B as described above, so that the water droplet W3 is allowed to flow into the air suction port. It is prevented that the air is sucked together with the intake air 30 into the lower side of the vehicle 35 and enters the vehicle compartment 20 side.

  Further, when the water shielding plate 40 rotates backward B, the upper side of the lower plate 40c of the water shielding plate 40 that is close to the center of rotation (the middle plate 40b of the water shielding plate 40) is Since the distance from the moving center is smaller, the movement dimension at the time of the backward rotation B is reduced, so that the upper side of the lower plate 40c of the water shielding plate 40 is prevented from approaching the upper side of the air suction port 35. Therefore, the upper side of the air suction port 35 is suppressed from being narrowed by the upper side of the lower plate 40c of the water shielding plate 40 that rotates backward B. Therefore, the air 30 ′ in the inner space 12 of the front cowl 3 on the outer side of the water shielding plate 40 in the width direction of the vehicle body 2 is caused by the large negative pressure of the air suction port 35, and the rear plate of the front cowl 3. After passing through the rear space 12b between the air shield 7 and the water shielding plate 40, the air is smoothly sucked into the upper side of the air suction port 35. As a result, a sufficient amount of intake air at the air intake port 35 due to the operation of the blower 36 is ensured, that is, a sufficient amount of intake air is secured to the passenger compartment 20 side.

  And according to the said structure, the said effect that the inhalation | air-intake amount to the compartment 20 side is ensured enough, although the penetration | invasion of the water droplets W2, W3 to the compartment 20 side is prevented, said above-mentioned. As described above, this is achieved by the backward rotation B of the water shielding plate 40 toward the air suction port 35 in accordance with the negative pressure of the air suction port 35. In other words, in order to achieve the above effect, It is not necessary to provide a water shielding plate or to make the air 30 flow passage in the inner space 12 of the front cowl 3 from the vent hole 31 of the cowl louver 24 to the air suction port 35 into a more complicated labyrinth structure. is there. Therefore, the above effect can be achieved with a simple configuration.

  Here, when the air conditioner 33 is driven, the amount of intake air at the air inlet 35 due to the operation of the blower 36 is frequently changed by being increased or decreased. Since the negative pressure of the air suction port 35 changes in accordance with the operation of the blower 36, the front and rear rotations A and B of the cowl louver 24 in front of and behind the water shielding plate 40 are frequently repeated.

  For this reason, suppose that a weak portion such as a thin wall is formed in the middle plate 40b of the water shielding plate 40, and the water shielding plate 40 is rotated forward and backward A and B by repeated bending of the weak portion. As a result, the fragile portion may be damaged early, causing a problem in the life of the water shielding plate 40.

  Therefore, as described above, the middle plate 40b of the water shielding plate 40 is bent, that is, a shape that is easily bent repeatedly while preventing the generation of stress, before the lower plate 40c of the water shielding plate 40, The rear rotation A and B is facilitated, and thereby the life of the water shielding plate 40 is improved.

  In addition, as described above, since the middle plate 40b of the water shielding plate 40 is shaped to be easily bent, the vehicle 1 collides with a certain object such as a pedestrian (front collision) while the vehicle 1 is traveling, and this object is the cowl louver. When the vehicle 24 collides from above, the middle plate 40b of the water shielding plate 40 is easily bent and deformed, and the impact force due to the collision of the object is reduced. Therefore, the object is prevented from being damaged by the reaction force of the impact force.

  Although the above is based on the illustrated example, the water shielding plate 40 may be integrally formed with the cowl louver 24. Further, the front and rear rotations A and B with respect to the cowl louver 24 may be based on a pivotal support, or may be a combination of a pivotal support and a spring material.
