B. Prior art In general, a front fascia made of resin has a bumper part and an apron part, the bumper part is fastened together with a radiator grille to a bumper reinforcement, and the bumper reinforcement is fixed to the vehicle body. attached to the absorber. If the apron part is small, the apron part 71 is screwed onto the stay 73 protruding from the side member 72 with screws 74, as shown in FIG. As shown in FIG.
A bracket 78 protruding from the housing is brought into contact with the bracket 78 and screwed into place by a bolt 79.

On the other hand, in order to effectively guide the wind toward the radiator from the radiator grill provided on the front fascia, conventionally a single air guide plate 81 made of rubber is attached to the front cross member 80 as shown in FIG. The front end of the vehicle is connected to the apron part 82.
supported above.

C Problems to be solved by the invention In the conventional example with the above configuration, it is necessary to fix the stays and brackets that fix the apron part to the vehicle body such as side members, and in the case of large apron parts, the shape A retainer is also required for retention. Furthermore, in consideration of the fact that the apron moves forward and backward in the event of a light collision, the front end of the wind guide plate is only supported on the apron, and the wind guide plate is made of rubber, which is weak in strength. It does not function as a reinforcement member for the front fascia. Additionally, in recent years, a baffle plate is sometimes installed on the underside of the vehicle between the front fascia and the radiator in order to improve aerodynamic performance, and in this case, the baffle plate and the baffle plate do not have to be installed separately. Must not be.

The purpose of this invention is to improve the rigidity of the air guide member by constructing it with an upper air guide plate and a lower straightening plate, and to support the apron part at the front end of the vehicle, thereby solving the above-mentioned problems in the front fascia. The objective is to provide a mounting structure for

D. Measures to solve the problem The air guide member installed from the radiator to the facia apron consists of an upper baffle plate that guides the wind toward the radiator through the radiator grille, and an upper baffle plate that guides the wind toward the radiator through the radiator grille, and a The lower baffle plate that rectifies the wind flowing downward is formed in a double structure, and the rear end of the wind guiding member is fixed to the cross member or side member of the vehicle, and the front end is equipped with a fascia apron. part is supported.

E Effect The wind guiding member whose rear end is supported by the cross member or side member of the vehicle has a double structure of an upper wind guiding plate and a lower straightening plate, and has high rigidity. Asia apron part is strongly supported. Wind flowing from the radiator grille toward the radiator is effectively guided to the radiator by the upper baffle plate, and wind flowing below the front fascia is rectified by the lower baffle plate to prevent turbulence below the vehicle.

F. Embodiment FIGS. 1 and 2 show an embodiment of the present invention, in which FIG. 1 is an exploded perspective view taken along the line - in FIG. 3, and FIG. 2 is a sectional view taken along the - line.

In FIG. 3, 10 is a front fascia made of resin, and the upper fascia bumper part 11
, a lower facia apron part 12, and a radiator grille 13 that is integrally provided with the facia apron part 12 at the center of the front of the vehicle.

In FIG. 1, 21 is a side member extending in the longitudinal direction on both sides of the vehicle, and 22 is a front cross member connecting the side members 21 on both sides. A bumper shock absorber 24 is attached to a bracket 23 projecting from the side member 21, and its tip 241 is screwed onto the bumper reinforcement 16 as shown in FIG.
A fascia bumper portion 11 and a radiator grille 13 are fastened together to the bumper reinforcement 16 with bolts 14. The radiator grille 13 is molded by injection molding from polypropylene resin, and has a boss 131 projecting downward, a bumper part holding part 132, and a lower part thereof.
An apron part holding part 133 is connected thereto, and a boss 134 protrudes downward at the tip of the holding part. The fascia apron part 12 is rim-molded from urethane resin, and its inner end is held in the holding part 13 by the holding part 132.
It is held at 4. Further, a boss 134 is fitted into a mounting hole 122 of a mounting portion 121 extending inward from the lower end of the fascia apron portion 12, and a washer 15 is screwed from below with a screw 17, so that the fascia apron portion 12 is attached to the radiator grill 13. is integrally combined with

The air guide member 30 includes an upper air guide plate 31 and a lower baffle plate 32 provided at a predetermined distance from the upper air guide plate 31. In this embodiment, the upper baffle plate 31 and the lower baffle plate 32 are integrally blow-molded into a double structure using polypropylene resin. This air guiding member 30
At the rear end of the vehicle, there is a mounting portion 33 extending 3 in the width direction of the vehicle.
Bolts 25 are screwed into the mounting seats 221 of the front cross member 22, thereby fixing the air guide member 30 to the front cross member 22. Further, on the side of the vehicle, a mounting portion 34 is provided upright from the upper baffle plate 31, and the mounting portion 34 is fixed to the bracket 23 with bolts 27 and nuts 28. On the other hand, the upper baffle plate 31 has three elongated holes 311 extending in the longitudinal direction of the vehicle in the vehicle width direction.
The bosses 131 of the radiator grille 13 are fitted into the elongated holes 311, and the washer 29 is screwed from below with the screws 26 to connect the air guide member 30 and the fascia apron portion 12. Concatenated. That is, the fascia apron portion 12 is supported by the front end of the air guide member 30. In addition, in FIG. 2, 40 is a radiator, which is elastically supported on the vehicle body by a mounting member (not shown).

In this embodiment configured in this manner, the air flowing from the radiator grille 13 toward the radiator 40 is effectively guided by the upper baffle plate 31, and the air flowing from below the front fascia 10 toward the vehicle is rectified at the lower part. The flow is rectified by the plate 32 and turbulent flow is prevented from occurring. Furthermore, when the bumper shock absorber 24 retracts and the front fascia 10 moves toward the rear of the vehicle during a light collision, the boss 131 of the radiator grille 13 moves rearward within the elongated hole 311, and the fascia apron portion 12 also moves rearward. Light collision performance is not compromised. Furthermore, there is a certain distance from the connecting part between the facia apron part 12 and the air guide member 30 to the leading edge of the facia apron part 12, and even if the facia apron part 12 runs on a curb or the like, the facia apron part Since 12 is made of flexible urethane and the radiator grille 13 is made of elastic polypropylene, the fascia apron portion 12 can escape upward, thereby preventing damage to it. Furthermore, since the facia apron portion 12 is held in the vehicle width direction by the highly rigid air guiding member 30 made of polypropylene and blow-molded in a double structure, the facia apron portion 12 is held at high temperatures.
It also does not "dag" downward due to thermal expansion. Further, since the air guiding member 30 is screwed to each part, it is easy to attach and detach, and the maintainability of the radiator 40 and its surroundings is improved.

According to the above embodiment, the air guide member 30 is blow molded, but if the upper air guide plate 31 and the lower baffle plate 32 are integrated with a predetermined interval and have a predetermined rigidity, The structure is not limited in any way. Moreover, although the radiator grill 13 and the fascia apron portion 12 have been described as separate bodies, they may be integrally molded. Further, although the boss 131 of the radiator grille 13 is inserted into the elongated hole 311 of the air guide member 30 to allow movement of the fascia apron portion 12 in the longitudinal direction of the vehicle, the boss is provided on the side of the air guide member 30, The boss may be fitted into a long hole in the radiator grille 13. Furthermore, instead of the radiator grille 13, the fascia apron portion 12 is directly connected to the air guide member 3.
May be connected to 0.

G. Effect of the invention According to the invention, the rear end of the highly rigid air guide member is fixed to the cross member or side member of the vehicle, and the fascia apron is supported on the front end of the rear end of the fascia. There is no need for stays, brackets, etc. that are used only to support the apron portion, and the structure can be simplified. In addition, the air guide member has a double structure of an upper air guide plate and a lower rectifying plate to increase its rigidity, so the air guide member functions as a support member for the fascia apron while effectively connecting the radiator from the radiator grill to the radiator. Since it guides wind and effectively prevents turbulence below the vehicle, it is possible to further simplify the structure and improve assembly efficiency compared to the case where the baffle plate and the baffle plate are provided separately.
