次に、作用について説明する。
このように構成された車両用エアガイド20,21をラジエータコアサポート１に装着するには、図８、９に示すように、車両用エアガイド20,21の各係止爪１４を、それぞれ対応するラジエータコアサポートサイド5,6のリブ９で区切られた空間内におけるコ字状断面の対向する内側の壁部に挟持させた状態で係止させることにより車両用エアガイド２０をラジエータコアサポート１に装着する。
なお、係止爪１４の詳細な形状や固定位置については適宜設定できる。 Next, the operation will be described.
In order to mount the vehicle air guides 20 and 21 thus configured on the radiator core support 1, as shown in FIGS. 8 and 9, the respective locking claws 14 of the vehicle air guides 20 and 21 correspond respectively. The radiator air core 20 is supported by the radiator core support 1 by holding the air guide 20 in a state where the air core 20 is held between the opposing inner walls of the U-shaped cross section in the space defined by the ribs 9 of the radiator core support sides 5 and 6. Attach to.
In addition, about the detailed shape and fixing position of the latching claw 14, it can set suitably.

従って、図１に示すように、ラジエータコアサポート１に装着された車両用エアガイド２０は、車両用エアガイド20,21がラジエータコアサポート１のラジエータコアサポートサイド5,6から車両前方側へ張り出した状態で車両上下方向に延設されることとなる。   Therefore, as shown in FIG. 1, the vehicle air guide 20 mounted on the radiator core support 1 has the vehicle air guides 20 and 21 projecting from the radiator core support sides 5 and 6 of the radiator core support 1 to the front side of the vehicle. In this state, the vehicle is extended in the vertical direction.

また、図９に示すように、車両用エアガイド２０が装着されたラジエータコアサポート１には、各サイドメンバ取付部7,8にバンパステイ１６が締結されると共に、該パンパステイ１６にバンパアーマチュア１７が車両用エアガイド20,21の開口部１３を貫通した状態で固定される。   Further, as shown in FIG. 9, the radiator core support 1 to which the vehicle air guide 20 is mounted is fastened with bumper stays 16 at the side member mounting portions 7 and 8, and a bumper armature 17 is attached to the pan pasty 16. The vehicle air guides 20 and 21 are fixed in a state of passing through the openings 13.

この際、各車両用エアガイド20,21の屈折部２７ａを車幅方向へ屈折させた状態で金属製のバンパアーマチュア１７に密着させてシールすることができる。   At this time, the refracting portions 27a of the vehicle air guides 20 and 21 can be sealed by being brought into close contact with the metal bumper armature 17 while being refracted in the vehicle width direction.

さらに、図示を省略する熱交換器がラジエータコアサポート１の開口部R1,R2に対面した状態で図示を省略するファンと共に車体側に搭載される。
なお、熱交換器はラジエータコアサポート１の車両前方側または車両後方側のどちらに搭載しても良い。 Further, a heat exchanger (not shown) is mounted on the vehicle body side together with a fan (not shown) in a state of facing the openings R1, R2 of the radiator core support 1.
The heat exchanger may be mounted on either the vehicle front side or the vehicle rear side of the radiator core support 1.

また、各車両用エアガイド20,21の開口部１３付近を除く車両前方側縁部には複雑な形状の図外の樹脂製のバンパフェイシアが配置されると共に、車両上下側縁部には図外の金属製の車体フレームが配置される。
この際、各車両用エアガイド20,21の屈折部２７ａを車幅方向へ屈折させた状態でバンパフェイシアに良好に密着させることができる。 Further, a resin bumper fascia having a complicated shape, not shown, is arranged on the vehicle front side edge except for the vicinity of the opening 13 of each of the vehicle air guides 20 and 21, and a vehicle bumper fascia is shown on the vehicle vertical side edge. An outer metal body frame is arranged.
At this time, the refracting portions 27a of the vehicle air guides 20, 21 can be satisfactorily adhered to the bumper fascia while being refracted in the vehicle width direction.

従って、前述したように、各車両用エアガイド20,21において、開口部１３の周囲を除く屈折部２７ａの剛性がその他の部位の屈折部２７ｂに比べて高くなっているため、金属製のバンパアーマチュア１７や車体フレームに対しては強く当接した状態でシールできると同時に、樹脂製のバンパフェイシアには弱く当接した状態でシールでき、当接する対象に適した強弱で当接させてシールすることができる。   Therefore, as described above, in each of the air guides 20 and 21 for the vehicle, the rigidity of the refracting portion 27a excluding the periphery of the opening 13 is higher than that of the refracting portion 27b in other portions. The armature 17 and the vehicle body frame can be sealed in a strong contact state, and at the same time, the resin bumper fascia can be sealed in a weak contact state. be able to.

また、ラジエータコアサポート１の熱交換器は、開口部R1,R2から車両走行風またはファンによる強制風をコア部に通過させて熱交換を行う。
この際、車両用エアガイド20,21は、車両走行風またはファンによる強制風を整流化させてスムーズに熱交換器の前方へ導く導風板として機能する。
また、エンジン側の熱気が主に車両側方から熱交換器の前方へ吹き返すのを防止する防風板として機能する。 Further, the heat exchanger of the radiator core support 1 performs heat exchange by passing vehicle running wind or forced air from a fan through the openings R1 and R2 through the core.
At this time, the vehicle air guides 20 and 21 function as a wind guide plate that rectifies the vehicle traveling wind or the forced wind generated by the fan and smoothly guides it to the front of the heat exchanger.
Moreover, it functions as a windbreak plate that prevents hot air on the engine side from blowing back mainly from the side of the vehicle to the front of the heat exchanger.

次に、効果を説明する。
以上、説明したように、本実施例１の車両用エアガイド構造にあっては、ラジエータコアサポート１のラジエータコアサポートサイド5,6から車両前方側へ張り出した状態で車両上下方向に延設された樹脂製の車両用エアガイド構造において、車両用エアガイド20,21を、２つの表皮22,23の間に柱部２４と空間２５が交互に配置された中空構造で構成したため、軽量且つ柔軟性に優れ、別体の弾性部材を用いることなく、車体側とのシール性能を良好にできる。 Next, the effect will be described.
As described above, in the vehicle air guide structure according to the first embodiment, the radiator core support 1 extends in the vehicle vertical direction in a state of projecting from the radiator core support sides 5 and 6 toward the vehicle front side. In the resin air guide structure made of resin, the vehicle air guides 20 and 21 are formed of a hollow structure in which the column portions 24 and the spaces 25 are alternately arranged between the two skins 22 and 23, so that the light weight and flexibility are achieved. The sealing performance with the vehicle body can be improved without using a separate elastic member.

また、車両用エアガイド20,21の柱部２４及び空間２５を車両上下方向に延設したため、車幅方向へより撓みやすくなり、車体側（主にバンパフェイシア）とのシール性を向上できる上、車両衝突時に剛体として作用せず、好適となる。   In addition, since the column portions 24 and the spaces 25 of the vehicle air guides 20 and 21 are extended in the vehicle vertical direction, the vehicle air guide 20 and 21 can be more easily bent in the vehicle width direction, and the sealing performance with the vehicle body side (mainly bumper fascia) can be improved It does not act as a rigid body at the time of a vehicle collision, and is suitable.

また、車両用エアガイド20,21の少なくとも車両側前方縁部に複数のスリット２６を設けて車幅方向に屈折可能な屈折部２７を形成すると共に、この屈折部２７を車体側と密着させてシールしたため、別体の弾性部材を用いることなく、車体側とのシール性能をさらに向上できる。   In addition, a plurality of slits 26 are provided at least on the vehicle-side front edge of the vehicle air guides 20 and 21 to form a refracting portion 27 that can be refracted in the vehicle width direction, and the refracting portion 27 is in close contact with the vehicle body side. Since the sealing is performed, the sealing performance with the vehicle body can be further improved without using a separate elastic member.

さらに、素材の適宜の箇所において、他の部位に比べて薄肉にした屈折部３６ａ〜３６ｅ（一点鎖線で図示）を形成する。なお、屈折部３６ａ〜３６ｅは素材に熱を加えながら溶解させる、または、表皮の片側に切欠を入れることにより容易に形成できる。   Furthermore, the refraction parts 36a to 36e (illustrated by a one-dot chain line) that are thinner than other parts are formed at appropriate portions of the material. The refracting portions 36a to 36e can be easily formed by dissolving the material while applying heat or by making a notch on one side of the skin.

そして、両垂直面部31,32を屈折部３６ａで所定の角度に屈折した後、各挟み込み部３４を屈折部３６ｂで両垂直面部31,32の内側に屈折し、さらに、図１４に示すように、挟み込み部３４の先端側３４ａを屈折部３６ｃ〜３６ｅで屈折させながら第２垂直面部３２の開口部３５ｂを介して挟み込み部３４の開口部３５ａに挿通固定して折り込むことにより、接続面部３３を形成して立体形状とすることができる。   Then, both the vertical surface portions 31 and 32 are refracted at a predetermined angle by the refracting portion 36a, and then each sandwiched portion 34 is refracted inside the both vertical surface portions 31 and 32 by the refracting portion 36b, and as shown in FIG. The connecting surface portion 33 is formed by inserting and fixing to the opening portion 35a of the sandwiching portion 34 through the opening portion 35b of the second vertical surface portion 32 while refracting the distal end side 34a of the sandwiching portion 34 by the refracting portions 36c to 36e. It can be formed into a three-dimensional shape.

従って、本実施例１の車両用エアガイド３０は、展開形状での製品梱包となるため、荷姿が非常に良く、物流費の削減が可能となる。   Accordingly, since the vehicle air guide 30 according to the first embodiment is a product package in an unfolded shape, the packaging shape is very good, and the distribution cost can be reduced.

また、螺子や接着剤等の締結手段を使用せずに簡便な作業で組み立てられるため、作業性が良い。   Moreover, since it is assembled by a simple operation without using a fastening means such as a screw or an adhesive, workability is good.

また、挟み込み部３４の柱部２４の目方向が折り込み方向に対して傾斜状となるため、挟み込み部３４の固定を堅固にして周辺部位の剛性を向上できると同時に、接続面部３３によって第１垂直面部３１と第２垂直面部３２を所定角度に堅固に維持できる。   Further, since the eye direction of the column part 24 of the sandwiching part 34 is inclined with respect to the folding direction, it is possible to firmly fix the sandwiching part 34 and improve the rigidity of the peripheral portion. The surface portion 31 and the second vertical surface portion 32 can be firmly maintained at a predetermined angle.

また、図１５に示すように、接続面部３３の柱部２４ａの目方向が両垂直面部31,32同士の所定角度を小さくするような応力に対して剛となる方向になるため、好適となる。   Further, as shown in FIG. 15, the eye direction of the column part 24a of the connection surface part 33 becomes a direction that becomes stiff against a stress that reduces the predetermined angle between the vertical surface parts 31 and 32, which is preferable. .

このように構成された車両用エアガイド３０は、図１０に示すように、実施例１と同様に、ラジエータコアサポート１に搭載された熱交換器３７等の周辺部材の配管等が第２垂直面部３２の開口部３５ｃに挿通配置される。   As shown in FIG. 10, the vehicle air guide 30 configured as described above has a second vertical pipe and the like of peripheral members such as the heat exchanger 37 mounted on the radiator core support 1, as in the first embodiment. The opening portion 35 c of the surface portion 32 is inserted and arranged.

そして、車両用エアガイド３０は、車両走行風または図外のファンによる強制風を熱交換器３７に導くようになっている。   The vehicle air guide 30 guides the vehicle traveling wind or the forced wind by a fan (not shown) to the heat exchanger 37.

この際、車両走行風を受けた第１垂直面部３１が後方へ屈折するのを接続面部３３で抑止して状態を維持でき、車両用エアガイド３０のばたつきや耐久性の低下を防止できる。   At this time, the connection surface portion 33 can prevent the first vertical surface portion 31 that has received the vehicle traveling wind from being refracted rearward, so that the state can be maintained, and fluttering of the vehicle air guide 30 and deterioration of durability can be prevented.

以上、本実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。
例えば、車両用エアガイドの全体形状は車体側に応じて適宜変更できる。 Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.
For example, the overall shape of the vehicle air guide can be appropriately changed according to the vehicle body side.

また、本実施例１では、スリットの間隔を変えることにより、屈折部の剛性に強弱を設定したが、スリットの深さを変えても良い。
同様に、バンパフェイシアと当接する屈折部の中空構造をスリットの深さ付近まで潰すことにより、脆弱化させて剛性が低くなるようにしても良い。 In the first embodiment, the strength of the refracting portion is set to be strong by changing the slit interval, but the slit depth may be changed.
Similarly, the hollow structure of the refracting portion that comes into contact with the bumper fascia may be crushed to near the depth of the slit so as to be weakened and have low rigidity.

また、本実施例１ではラジエータコアサポート１の左右両側に車両用エアガイドをそれぞれ設けたが、一方側にのみ設ける場合もあり得る。   In the first embodiment, the vehicle air guides are provided on both the left and right sides of the radiator core support 1, respectively, but may be provided only on one side.

さらに、本実施例１の柱部２４が表皮と直交する方向へ直線状に形成される場合について説明したが、図１６に示すように、空間２５が台形状となるように傾斜状の柱部２４を採用する等、適宜設定できる。   Furthermore, although the case where the column part 24 of the first embodiment is formed linearly in a direction perpendicular to the skin has been described, as shown in FIG. 16, the column part inclined so that the space 25 has a trapezoidal shape. For example, 24 can be used.
