In such a cooling device, in order to further improve the cooling efficiency, an air guide plate such as an air guide or an air duct for introducing outside air into the heat radiating part may be arranged in the front part of the cooling device.

  On the other hand, from the viewpoint of pedestrian protection in the vehicle, it is required to provide a space between the bumper and the structure in the engine room in order to reduce the impact value generated at the time of a collision. However, since the above-mentioned baffle plate is arranged between the bumper and the cooling device, the space for absorbing shock is narrowed.

  As described above, since the baffle plate may deteriorate the shock absorbing power, the baffle plate is composed of a plurality of members so that the baffle plate also functions as a cushioning member and an entrainment prevention member for the baffle plate. There are cases. However, since the baffle plate is apt to vibrate in the vertical direction of the vehicle when the vehicle is traveling, a minute gap is created between a plurality of members, and hot air of the engine may blow back through the gap. There was a point. Therefore, for example, "Patent Document 1" describes a technique for joining the members well to prevent the hot air of the engine from being blown back and to join the members easily.

In addition, as shown in FIG. 2, a tip portion is provided on the vehicle front side of the lower guide 16 to prevent the collision of the obstacle when the obstacle collides from the vehicle front. A buffer portion 16b is formed by bending downward.
Three mounting portions 16c are formed on the vehicle rear side of the lower guide 16 for fixing itself to an impact absorbing member described later. Further, on both sides of the lower guide 16, there are provided connected points to which side guides 14 and 15 to be described later are attached.

Next, the side guides 14 and 15 will be described. Since the side guides 14 and 15 have symmetrical shapes, only the side guide 15 will be described here.
As shown in FIGS. 3, 4, and 5, the side guide 15 is formed by bending a sheet metal or is formed of a high-strength resin, and the vertical wall portion 15 a standing upright is connected to the lower guide 15. It has the bottom face part 15b.

The upper portion of the vertical wall portion 15a is further bent to form two protrusions 15c and 15d as deformation preventing portions, which improves bending strength and twisting strength in the vertical direction. A step portion 15e is formed in the middle step portion of the vertical wall portion 15a, and a screw functioning as a fixing portion for fixing the side guide 15 to the vehicle body 2 is provided at a portion between the protruding portion 15d and the step portion 15e. The hole 15f is formed. Further, a portion between the ridges 15c and 15d is bent one step to form a flat surface portion 15g, and the flat surface portion 15g is formed with a screw hole 15h functioning as a fixing portion.
A bulging portion 15i is formed above the protruding portion 15c of the vertical wall portion 15a so as to bulge a part thereof in a protruding direction. By providing the bulging portion 15i, when the side guide 15 is attached to the vehicle body 2 described later, interference with a member protruding from the vehicle body 2 side is prevented.

As shown in FIG. 5C, the bottom surface portion 15b is provided with a mounting hole 15j and a positioning pin 15k (convex portion) that respectively function as a connecting portion. The mounting hole 15j provided on the front side in the front-rear direction of the vehicle body 2 functions as a front connecting portion, and the positioning pin provided on the rear side functions as a rear connecting portion.
As shown in FIG. 6, the mounting hole 15j is used in a state of being aligned with the mounting hole 16d formed in the lower guide 16. The positioning pin 15k is used to align the mounting holes 15j and 16d, and the positioning pin 15k is inserted into the recess 16e formed in the lower guide 16 to align the positions of the mounting holes 15j and 16d. It The positioning pin 15k, which is a convex portion, and the concave portion 16e both function as a positioning portion.
In this embodiment, the positioning pin 15k that is a convex portion is provided on the side guide 15 side and the concave portion 16e is provided on the lower guide 16 side that is a connecting member. However, the convex portion is on the connecting member side and the concave portion is on the side guide side. It may be configured to be provided in.

  FIG. 7 is a diagram for explaining the connection between the side guides 14 and 15 and the lower guide 16 which is a connecting member. When the positioning pin 15k is inserted into the recess 16e and the positions of the mounting holes 15j and 16d are aligned as described above, the outer bush 17 having a hole portion at the center is first inserted into the mounting holes 15j and 16d. To be done. The outer bush 17 formed of an elastic member such as resin has a flange portion 17a having a cylindrical shape in plan view, and a pair of bent leg portions 17b integrally provided on the flange portion 17a. The outer bush 17 is inserted into the mounting holes 15j and 16d by the pair of leg portions 17b deforming inward, and the leg portions 17b elastically deform outward after passing through the mounting holes 15j and 16d. As a result, a slight engagement force is applied between the side guides 14 and 15 and the lower guide 16. However, this engagement force is released when a weak external force is applied, and in that case, the outer bush 17 is pulled out from each mounting hole 15j, 16d and the connection state between the side guides 14, 15 and the lower guide 16 is released. It

After the outer bush 17 is inserted into each of the mounting holes 15j and 16d, the inner pin 18 functioning as a clip member is inserted into the hole portion of the outer bush 17 as shown in FIG. The inner pin 18 made of a low-rigidity resin such as polyethylene or polypropylene has a flange portion 18a having a circular shape in plan view and a shaft portion 18b having a diameter that fits snugly into the hole portion of the outer bush 17. ..
When the leg portion 17b of the outer bush 17 expanded by the shaft portion 18 is inserted into the outer bush 17 and engaged with the shaft portion 18b when the leg portion 17b moves in the closing direction by its elasticity. The joining portion 18c is formed by reducing the diameter, and the fragile portion 18d is formed by reducing the diameter at a portion located immediately below the collar portion 18a.
By inserting the inner pin 18 into the outer bush 17, the side guides 14 and 15 and the lower guide 16 are connected. This connection force has a strength that is not released when the vehicle 1 is traveling normally.

Next, a mounting structure of the baffle plate 13 to the vehicle body 2 will be described with reference to FIG. As shown in FIG. 8, the baffle plate 13 has each side guide 14, 15 fixed to a bumper beam 20 which is an immovable member constituting the vehicle body 2 by four bolts 19.
The bumper beam 20 is provided with a foot-discharging bar 21 as a shock absorbing member that absorbs an impact value of the object when the object collides with the front portion of the vehicle body 2. The foot-discharging bar 21 is attached to the bumper beam 20 so as to be swingable toward the rear side of the vehicle body, which is the direction indicated by the arrow in FIG. 8, and when an object collides with the front portion of the vehicle body 2, The impact value applied to the object is alleviated by the foot-displacing bar 21 that first collides with the object swinging to the rear side of the vehicle body.
The lower guide 16 is fixed to the foot-discharging bar 21 with three bolts 19. In this way, the side guides 14 and 15 are fixed to the bumper beam 20, and the lower guide 16 is fixed to the foot sweep bar 21, whereby the attachment of the baffle plate 13 to the vehicle body 2 is completed.

With the above configuration, the air guide plate 13 that guides the cooling air to the intercooler 10 and that includes the side guides 14 and 15 and the lower guide 16 configures the vehicle body 2 by the bolts 19 and the side guides 14 and 15, respectively. The lower guide 16 is fixed to the bumper beam 20 which is an immovable member, and the foot sweep bar 21 supported by the bumper beam 20. As a result, since the wind guide plate 13 is firmly fixed to the vehicle body 2 even when the wind guide plate 13 receives vibrations in the vertical direction of the vehicle while the vehicle 1 is traveling, the generation of a gap is prevented and the hot air of the engine is prevented. It is possible to prevent the occurrence of the problem of the blowback.
Further, when an external force is applied to the baffle plate 13 from the front side of the vehicle with the above-described configuration, the engaging portion 18c or the fragile portion 18d of each inner pin 18 is broken by the external force and each inner pin 18 is removed from each outer bush 17. Since the connection state between the side guides 14 and 15 and the lower guide 16 is released, the wind guide plate 13 can be disassembled to prevent the impact absorbing power from being deteriorated.

At this time, the mounting hole 15j (in the case of the side guide 15) that functions as a connecting portion and the outer bush 17 and the inner pin 18 that are fitted into the mounting hole 15j are forward in the front-rear direction of the vehicle 1 than the screw hole 15h that functions as a fixing portion. Since it is provided in the outer bush 17, the inner pin 18, the positioning pin 15k, and the recess 16e, which are inserted into the mounting holes 15j and 16d while maintaining the fixing in the screw holes 15f and 15h, are input. The side guides 14 and 15 and the lower guide 16 can be separated from each other at a desired location by using the generated force, and the deterioration of the impact absorbing force can be prevented.
Further, since the side guides 14 and 15 and the lower guide 16 are arranged in front of the intercooler 10 in the front-rear direction of the vehicle 1, the side guides 14 and 15 are arranged outside the intercooler 10 in the vehicle width direction. The external air can be efficiently introduced into the intercooler 10, and the cooling efficiency of the intercooler 10 can be improved.

Further, as the connecting portion, there is a mounting hole 15j that functions as the front connecting portion and a positioning pin 15k that functions as the rear connecting portion, and the connecting force of the front connecting portion is set higher than that of the rear connecting portion. Therefore, the moment acting on the front connecting portion can be increased, and the connection between the side guides 14 and 15 and the lower guide 16 can be easily released.
Further, since the rear side connection point is the positioning pin 15k, positioning can be easily performed when the side guides 14 and 15 and the lower guide 16 are connected, and the assembling process can be facilitated to improve work efficiency. it can.

Further, in the baffle plate 13, since the lower guide 16 is fixed to the foot sweeping bar 21, it is possible to prevent the foot sweeping bar 21 from swinging and absorbing a shock when an external force is applied to the front of the vehicle body 2. Instead, the lower guide 16 is disengaged from the side guides 14 and 15.
As a result, it is possible to prevent the impact absorbing power from deteriorating, and the lower guides 16 dropped from the side guides 14 and 15 due to the disconnection are fixed to the foot bar 21 so that the lower guides 16 drop from the vehicle body 2. Therefore, it is possible to prevent the occurrence of problems such as the lower guide 16 coming off from the vehicle body 2 and the lower guide 16 colliding with another object or remaining on the road to come into contact with the following vehicle.

  Further, in the baffle plate 13, since the side guides 14 and 15 are provided with the ridges 15c and 15d (in the case of the side guide 15) as the deformation preventing portions, the side guides 14 and 15 can be extended in the vertical direction. Since the bending strength and the torsional strength are improved, it is possible to reliably prevent the side guides 14 and 15 from being deformed by wind pressure even when the vehicle 1 is traveling at high speed, and improve the air guiding performance to cool the side guides. The efficiency can be improved. Further, the side guides 14 and 15 are arranged such that the free ends of the side guides 14 and 15 that face the screw holes 15f and 15h are directed toward the front in the front-rear direction of the vehicle 1; Since it is formed so as to incline toward the outer side in the vehicle width direction as it goes to the front side, traveling wind can be collected from a wide range and cooling efficiency can be improved.

Further, in the baffle plate 13, the screw holes 15f and 15h, which are the fixing portions, are fixed to the front end surface of the vehicle body 2, and the mounting hole 15j that functions as a connection point is substantially orthogonal to the road surface that is orthogonal to the front end surface described above. It is provided on the upper surface of the lower guide 16 which is in a parallel plane.
With this configuration, when an object collides with the front surface of the vehicle body 2 and an external force is applied, a load in the shearing direction does not act on each bolt 19 that fixes each screw hole 15f, 15h, but each mounting hole 15j is fixed. A load in the shearing direction acts on the inner pin 18 that operates.
Therefore, when an object collides with the front surface of the vehicle body 2 and an external force acts, the side guides 14 and 15 are prevented from falling off the vehicle body 2, and the side guides 14 and 15 are connected to the lower guide 16. The state is released, and it is possible to suppress the deterioration of the shock absorbing power.

FIG. 9 shows a side guide used in the second embodiment of the present invention. The side guide 22 shown in FIG. 9 is used in place of the side guide 15, and in place of the side guide 14, the side guide 22 and a side guide (not shown) having a target shape are used.
The side guide 22 is formed by bending a metal plate or is made of high-strength resin, and has a vertical wall portion 22a and a bottom surface portion 22b like the side guide 15. Similar to the side guide 15, the vertical wall portion 22a is formed with ridge portions 22c and 22d as deformation preventing portions, step portions 22e, and screw holes 22f functioning as fixing portions, and between the ridge portions 22c and 22d. A flat surface portion 22g and a screw hole 22h functioning as a fixing portion are formed in the. Further, a bulging portion 22i is formed above the protruding portion 22c.

As shown in FIG. 8C, the bottom surface portion 22b is provided with two claw members 22j and one positioning member 22k, each of which functions as a connecting portion. Each claw member 22j functions as a front connecting portion, and the positioning member 22k functions as a rear connecting portion.
The side guides 22 and the lower guides 16 are connected to each other by engaging the respective claw members 22j with engaging holes (not shown) formed in the lower guide 16, which the claw members 22j can engage with. The positioning member 22k is fitted into a hole (not shown) formed in the lower guide 16 so that the above-described engagement holes and the claw members 22j are aligned with each other.

With the above configuration, when an external force is applied from the front of the vehicle to the wind guide plate 13 to which the side guides 22, the side guides 22 and the side guides (not shown) of the target shape and the lower guide 16 are connected, each claw member 22j is caused by the external force. Since the broken state causes the connection between the side guide 22 and the side guide (not shown) and the lower guide 16 to be released, it is possible to prevent the shock absorbing force from being deteriorated by disassembling the baffle plate 13.
Further, since the side guide 22 and the lower guide 16 can be connected without using any other member, the configuration can be simplified and the cost can be reduced as compared with the first embodiment.
