Description
本発明は、フロントバンパの背面側に取り付けられ、フロントバンパの空気取り入れ口から取り入れられた冷却風を熱交換器等に案内する車両のエアガイド構造に関する。 The present invention relates to a vehicle air guide structure that is attached to the back side of the front bumper and guides the cooling air taken in from the air intake of the front bumper to a heat exchanger or the like.
車両の衝突時に、エアガイドとラジエータサポートサイドとの固定を外すことにより、エアガイドが剛体として作用するのを防止できる車両用のエアガイド構造がある（特許文献１参照）。 There is an air guide structure for a vehicle that can prevent the air guide from acting as a rigid body by removing the fixing between the air guide and the radiator support side in the event of a vehicle collision (see Patent Document 1).
しかしながら、上記先行技術文献によると、上記構造ではラジエータサポートサイドに対するエアガイドの固定解除により、剛体として作用するのを抑止するため、エアガイドの剛性は維持されたままとなる。ラジエータサポートサイドに対する固定解除が作用しなかった場合にはエアガイドが熱交換器と衝突した際、故障の原因となる。また、ラジエータサポートの固定部には熱交換器を固定しており、衝撃が入力された場合に、熱交換器と固定部が衝突し、熱交換器が破損することも考えられる。 However, according to the above prior art document, in the above structure, the rigidity of the air guide is maintained because the air guide is prevented from acting as a rigid body by releasing the fixing of the air guide to the radiator support side. If the release of the fixing to the radiator support side does not work, the air guide may collide with the heat exchanger and cause a malfunction. Further, a heat exchanger is fixed to the fixed portion of the radiator support, and when an impact is input, the heat exchanger and the fixed portion may collide with each other and the heat exchanger may be damaged.
本発明は、エアガイド構造を利用した衝撃吸収構造により、車両後方にある熱交換器の破損を防止できる車両のエアガイド構造を提供することを目的とする。 An object of the present invention is to provide a vehicle air guide structure capable of preventing damage to a heat exchanger at the rear of the vehicle by a shock absorbing structure using an air guide structure.
本発明は、上記課題を解決するため、フロントバンパの空気取り入れ口の後方であって、該フロントバンパに配設される車両のエアガイド構造において、前記フロントバンパの後方に配置された熱交換器の前方にエアガイドを設け、該エアガイドには前記熱交換器が配置された車両後方に向かって延出壁部を有し、かつ前記エアガイドの延出壁部基部には荷重吸収部が設けられていることにある。 In order to solve the above problems, the present invention is a heat exchanger arranged behind the air intake of the front bumper and behind the front bumper in the air guide structure of the vehicle arranged in the front bumper. An air guide is provided in front of the air guide, the air guide has an extending wall portion toward the rear of the vehicle in which the heat exchanger is arranged, and a load absorbing portion is provided at the base of the extending wall portion of the air guide. It is to be provided.
延出壁部に車両前後方向の荷重が入力された場合に、延出壁部基部には荷重吸収部が設けられているので、荷重吸収部に荷重が集中する。荷重吸収部に荷重が集中すると延出壁部が前後方向に沈み込むように変位し、荷重吸収部からの荷重を吸収する。これによって、熱交換器ほかの機器の損傷を防ぐことができる。 When a load in the front-rear direction of the vehicle is input to the extending wall portion, the load absorbing portion is provided at the base of the extending wall portion, so that the load is concentrated on the load absorbing portion. When the load is concentrated on the load absorbing part, the extending wall part is displaced so as to sink in the front-rear direction, and the load from the load absorbing part is absorbed. This prevents damage to the heat exchanger and other equipment.
以下本発明の実施の形態を、図面を参照しながら詳細に説明する。

It is composed of an extension wall portion 22 which is provided and is provided so as to project toward the rear of the vehicle body.
As shown in FIG. 2, the pair of partition walls 2f are provided so as to project rearward at positions on the upper side of the air guide main body 21 so as to face each other at regular intervals in the vertical direction. And the middle partition wall 2f2.
The extending wall portion 22 is supported between the upper partition wall 2f1 and the middle partition wall 2f2 by the partition walls 2f1 and 2f2, and toward the rear of the vehicle in which the heat exchanger 3 is arranged. It is configured to extend so as to face the heat exchanger 3. The air guide main body 21 provided with the extending wall portion 22 is formed with a notch hole 20a as an air intake port on the front side of the extending wall portion 22. The extension wall portion base is formed of a connecting member composed of a curved portion 23c and a vertical wall portion 24c that are connected to the upper partition wall 2f1 or the middle partition wall 2f2.
前記延出壁部２２は、図３に示すように、フロントバンパ１の車体後方側のエンジンルームに配置されている熱交換器３に向かって延出されており、熱交換器３に対向する後端には上下方向に延びる帯状の当接面部２２ａが側壁面２２ｂの後端縁部に設けられている。前記当接面部２２ａの上端には、図６および図７に示すように前記側壁面２２ｂの上端縁部に沿って車体前方に向けて延出された帯状の上壁面２２ｃが設けられ、上壁面２２ｃは途中から二股に分離され、前記側壁面２２ｂに沿った縁部２２ｃ１と、前記側壁面２２ｂから離れるように延出された上部側の当接面支持部２２ｃ２が設けられている。前記縁部２２ｃ１と当接面支持部２２ｃ２の間には、切欠孔２０ａ１が形成されている。なお、ここでいう当接面とは、衝撃が入力された際に熱交換機と当接可能に配置される部位のことである。
前記側壁面２２ｂに沿った縁部２２ｃ１は前端部が上方に向けて湾曲した湾曲部２３ｃ１を介して上方に向けて立ち上がる縦壁部２４ｃ１に連結されて仕切り壁２ｆ１下面に連結されている。前記側壁面２２ｂから離れるように延出された上部側の当接面支持部２２ｃ２は前端部が上方に向けて湾曲した湾曲部２３ｃ２を介して上方に向けて立ち上がる縦壁部２４ｃ２に連結されて仕切り壁２ｆ１下面に連結されている。

As shown in FIG. 3, the extending wall portion 22 extends toward the heat exchanger 3 arranged in the engine room on the rear side of the vehicle body of the front bumper 1 and faces the heat exchanger 3. At the rear end, a band-shaped contact surface portion 22a extending in the vertical direction is provided at the rear end edge portion of the side wall surface 22b. As shown in FIGS. 6 and 7, a band-shaped upper wall surface 22c extending toward the front of the vehicle body is provided at the upper end of the contact surface portion 22a along the upper end edge of the side wall surface 22b, and the upper wall surface is provided. The 22c is bifurcated from the middle, and is provided with an edge portion 22c1 along the side wall surface 22b and an upper contact surface support portion 22c2 extending away from the side wall surface 22b. A notch hole 20a1 is formed between the edge portion 22c1 and the contact surface support portion 22c2. The contact surface referred to here is a portion that is arranged so as to be able to contact the heat exchanger when an impact is input.
The edge portion 22c1 along the side wall surface 22b is connected to the vertical wall portion 24c1 whose front end portion is curved upward via the curved portion 23c1 and is connected to the lower surface of the partition wall 2f1. The upper contact surface support portion 22c2 extending away from the side wall surface 22b is connected to a vertical wall portion 24c2 that rises upward via a curved portion 23c2 whose front end portion is curved upward. It is connected to the lower surface of the partition wall 2f1.
That is, the contact surface support portion 22c2 on the upper side is provided with an extension wall portion base having a load absorbing portion A1 following the curved portion 23c2 and the vertical wall portion 24c2 from the contact surface support portion 22c2.
前記縦壁部２４ｃ２の前方側上端部には、図７に示すように車体前方に向けて延出された補強用のビード状の前壁部２５ｃ２が設けられている。この前壁部２５ｃ２は仕切り壁２ｆ１の下面に縦壁部２４ｃ２の前端部の位置から車体前方に向けて徐々に高さが低くなるように（高さＨ２が小さくなるように）前上がりに傾斜して延出されている。 As shown in FIG. 7, a bead-shaped front wall portion 25c2 for reinforcement extending toward the front of the vehicle body is provided at the front upper end portion of the vertical wall portion 24c2. The front wall portion 25c2 is inclined forward on the lower surface of the partition wall 2f1 so that the height gradually decreases from the position of the front end portion of the vertical wall portion 24c2 toward the front of the vehicle body (so that the height H2 becomes smaller). It has been postponed.
また、前記当接面部２２ａの下端には、図４に示すように前記側壁面２２ｂの下端縁部に沿って車体前方に向けて延出された帯状の下壁面２２ｄが設けられ、下壁面２２ｄは途中から二股に分離され、前記側壁面２２ｂに沿った縁部２２ｄ１と、前記側壁面２２ｂから離れるように延出された下部側の当接面支持部２２ｄ２が設けられている。
前記側壁面２２ｂに沿った縁部２２ｄ１は前端部が下方に向けて湾曲した湾曲部２３ｄ１を介して下方から上方に向けて立ち上がる縦壁部２４ｄ１上端部に連結されて仕切り壁２ｆ１の上面に連結されている。前記側壁面２２ｂから離れるように延出された下部側の当接面支持部２２ｄ２は前端部が下方に向けて湾曲した湾曲部２３ｄ２を介して下方から上方に向けて立ち上がる縦壁部２４ｄ２上端部に連結されて仕切り壁２ｆ２上面に連結されている。縁部２２ｄ１と当接面支持部２２ｄ２との間には、切欠孔２０ａ２が形成されている。
Further, as shown in FIG. 4, a band-shaped lower wall surface 22d extending toward the front of the vehicle body along the lower end edge of the side wall surface 22b is provided at the lower end of the contact surface portion 22a, and the lower wall surface 22d is provided. Is bifurcated from the middle, and is provided with an edge portion 22d1 along the side wall surface 22b and a lower contact surface support portion 22d2 extending away from the side wall surface 22b.
The edge portion 22d1 along the side wall surface 22b is connected to the upper end portion of the vertical wall portion 24d1 that rises from the lower side to the upper side via the curved portion 23d1 whose front end portion is curved downward, and is connected to the upper surface of the partition wall 2f1. Has been done. The lower contact surface support portion 22d2 extending away from the side wall surface 22b is the upper end portion of the vertical wall portion 24d2 that rises from the lower side upward through the curved portion 23d2 whose front end portion is curved downward. It is connected to the upper surface of the partition wall 2f2. A notch hole 20a2 is formed between the edge portion 22d1 and the contact surface support portion 22d2.
前記下部側の当接面支持部２２ｄ２は、図４および図５に示すように湾曲した湾曲部２３ｄ２を介して縦壁部２４ｄ２上端部に連結されている。この縦壁部２４ｄ２は上部側の当接面支持部２２ｃ２が連結される縦壁部２４ｃ２の長さに比較して長く形成されている。これは、下部側の当接面支持部２２ｄ２は、当接面部２２ａからの荷重を吸収するため、下部側の当接面支持部２２ｄ２と、湾曲部２３ｄ２と、縦壁部２４ｄ２を脆弱に構成して折れの起点となるように設計されており、荷重を効果的に吸収するように構成されている。すなわち、下部側の当接面支持部２２ｄ２の基端部では、当接面支持部２２ｄ２から、湾曲部２３ｄ２および縦壁部２４ｄ２と続く荷重吸収部Ａ２が設けられている。 The lower contact surface support portion 22d2 is connected to the upper end portion of the vertical wall portion 24d2 via a curved curved portion 23d2 as shown in FIGS. 4 and 5. The vertical wall portion 24d2 is formed longer than the length of the vertical wall portion 24c2 to which the contact surface support portion 22c2 on the upper side is connected. This is because the contact surface support portion 22d2 on the lower side absorbs the load from the contact surface portion 22a, so that the contact surface support portion 22d2 on the lower side, the curved portion 23d2, and the vertical wall portion 24d2 are fragilely configured. It is designed to be the starting point of breakage, and is configured to effectively absorb the load. That is, at the base end portion of the contact surface support portion 22d2 on the lower side, a load absorbing portion A2 is provided which continues from the contact surface support portion 22d2 to the curved portion 23d2 and the vertical wall portion 24d2.
前記縦壁部２４ｄ２の前方側下端部には、図５に示すように車体前方に向けて延出された補強用のビード状の前壁部２５ｄ２が設けられている。この前壁部２５ｄ２は仕切り壁２ｆ２の上面に沿って、縦壁部２４ｄ２の下部前端部の位置から車体前方に向けて徐々に高さが低くなるように（高さＨ１が小さくなるように）傾斜して延出されている。 As shown in FIG. 5, a bead-shaped front wall portion 25d2 for reinforcement extending toward the front of the vehicle body is provided at the front lower end portion of the vertical wall portion 24d2. The height of the front wall portion 25d2 gradually decreases from the position of the lower front end portion of the vertical wall portion 24d2 toward the front of the vehicle body along the upper surface of the partition wall 2f2 (so that the height H1 becomes smaller). It is sloping and extended.
次に上記実施の形態の作用を、図９を参照しながら説明する。
図９は、フロントバンパ１の背面側を示したもので、エンジン部品などの熱源Ｅからの熱が矢印のように熱交換器３の前方に回り込む事をエアガイド２の側壁面２２ｂが防いでいる。一方、フロントバンパ１の空気取り入れ口からエンジンルームに入り込む冷気Ｃはエアガイド２の側壁面２２ｂにより、熱源Ｅと混ざることなく冷気状態を維持したまま熱交換器３に当たり、熱交換器３の冷却を行う。
このとき、例えば、車体前方より荷重が加わって、フロントバンパ１が後方に押されて移動した場合、フロントバンパ１の背面に取り付けられているエアガイド２も車体後方に移動する。そして、エアガイド２に車体後方に向けて突出して設けられた延出壁部２２も車体後方に移動する。このとき、延出壁部２２に設けられた当接面部２２ａが熱交換器３の前面部に当接して係止され、フロントバンパ１およびエアガイド２の車体後方への移動を阻止される。
そして、車体前方からの荷重が必要以上に大きい場合には、当接面部２２ａの当たりによって熱交換器３が損傷する恐れが生じる。このとき、延出壁部２２は、下部側の縦壁部２４ｄ２を上部側の縦壁部２４ｃ２より長く形成して脆弱に構成しているので、当接面支持部２２ｄ２、湾曲部２３ｄ２、縦壁部２４ｄ２と続く荷重吸収部Ａ２が設けられていることから、下部側の当接面支持部２２ｄ２では、湾曲部２３ｄ２および縦壁部２４ｄ２が折れの起点となり、車体前方からの荷重を吸収する。
Next, the operation of the above embodiment will be described with reference to FIG.
FIG. 9 shows the back side of the front bumper 1, and the side wall surface 22b of the air guide 2 prevents the heat from the heat source E such as engine parts from wrapping around to the front of the heat exchanger 3 as shown by the arrows. There is. On the other hand, the cold air C entering the engine room from the air intake port of the front bumper 1 hits the heat exchanger 3 while maintaining the cold air state without being mixed with the heat source E by the side wall surface 22b of the air guide 2, and cools the heat exchanger 3. I do.
At this time, for example, when a load is applied from the front of the vehicle body and the front bumper 1 is pushed backward to move, the air guide 2 attached to the back surface of the front bumper 1 also moves to the rear of the vehicle body. Then, the extending wall portion 22 provided on the air guide 2 so as to project toward the rear of the vehicle body also moves to the rear of the vehicle body. At this time, the contact surface portion 22a provided on the extending wall portion 22 abuts on the front surface portion of the heat exchanger 3 and is locked, so that the front bumper 1 and the air guide 2 are prevented from moving to the rear of the vehicle body.
If the load from the front of the vehicle body is larger than necessary, the heat exchanger 3 may be damaged by the contact with the contact surface portion 22a. At this time, since the extending wall portion 22 is fragilely configured by forming the lower vertical wall portion 24d2 longer than the upper vertical wall portion 24c2, the contact surface supporting portion 22d2, the curved portion 23d2, and the vertical portion are vertically formed. Since the wall portion 24d2 and the load absorbing portion A2 following the wall portion 24d2 are provided, the curved portion 23d2 and the vertical wall portion 24d2 of the lower contact surface supporting portion 22d2 serve as the starting point of bending and absorb the load from the front of the vehicle body. ..
このように延出壁部２２に車両前後方向の荷重が入力された場合に、延出壁部２２基部には荷重吸収部Ａ（Ａ１，Ａ２）が設けられているので、荷重吸収部Ａに荷重が集中する。荷重吸収部Ａに荷重が集中すると延出壁部２２が前後方向に沈み込むように変位し、荷重吸収部Ａによって荷重を吸収する。これによって、熱交換器３ほかの機器の損傷を防ぐことができる。 When a load in the vehicle front-rear direction is input to the extending wall portion 22 in this way, the load absorbing portion A (A1, A2) is provided at the base of the extending wall portion 22, so that the load absorbing portion A is provided. The load is concentrated. When the load is concentrated on the load absorbing portion A, the extending wall portion 22 is displaced so as to sink in the front-rear direction, and the load absorbing portion A absorbs the load. As a result, damage to the heat exchanger 3 and other devices can be prevented.
前記エアガイド２の延出壁部２２には、車体後方に向けて対向する当接面部２２ａと、該当接面部２２ａを支持する当接面支持部２２ｄ２とを設けている。該当接面支持部２２ｄ２と前記エアガイド本体部２１の間には、前記エアガイド本体部２１に設けられた車両上下方向の縦壁部２４ｄ２と、該縦壁部２４ｄ２と前記当接面支持部２２ｄ２とを連結する湾曲部２３ｄ２とからなる前記荷重吸収部Ａ２が設けられている。また、前記縦壁部２４ｄ２から車両前方向に延出される前壁部２５ｄ２が設けられている。こうして、基部に縦壁部２４ｄ２があり、縦壁部２４ｄ２から車両前方向に延設される前壁部２５ｄ２があることにより、前壁部２５ｄ２で前後方向の剛性を向上させることができる。これにより、剛性の低い湾曲部２３ｄ２に荷重を集中させ易くなり当接面部２２ａの荷重吸収効果が向上する。 The extending wall portion 22 of the air guide 2 is provided with a contact surface portion 22a facing the rear of the vehicle body and a contact surface support portion 22d2 for supporting the contact surface portion 22a. Between the contact surface support portion 22d2 and the air guide main body portion 21, a vertical wall portion 24d2 in the vehicle vertical direction provided on the air guide main body portion 21, and the vertical wall portion 24d2 and the contact surface support portion are provided. The load absorbing portion A2 including the curved portion 23d2 connecting the 22d2 is provided. Further, a front wall portion 25d2 extending from the vertical wall portion 24d2 in the front direction of the vehicle is provided. In this way, the vertical wall portion 24d2 is provided at the base portion, and the front wall portion 25d2 extending from the vertical wall portion 24d2 in the front direction of the vehicle is provided, so that the rigidity of the front wall portion 25d2 in the front-rear direction can be improved. As a result, the load can be easily concentrated on the curved portion 23d2 having low rigidity, and the load absorbing effect of the contact surface portion 22a is improved.
前記当接面支持部２２ｃ２，２２ｄ２は当接面部２２ａの上下位置からそれぞれ車両斜め前方に向けて延出されて設けられ、該延出端からそれぞれ上下方向に湾曲部２３ｃ２，２３ｄ２を介して上下の縦壁部２４ｃ２，２４ｄ２に連結されてなるので、当接面支持部２２ｃ２，２２ｄ２が当接面部２２ａから車両上下方向に配置されることにより、熱交換器３に当接した際に熱交換器３に対して当接面部２２ａが対向する向きとなることを維持できる。 The contact surface support portions 22c2 and 22d2 are provided so as to extend from the vertical position of the contact surface portion 22a toward the diagonally forward direction of the vehicle, respectively, and move up and down from the extending ends in the vertical direction via the curved portions 23c2 and 23d2, respectively. Since it is connected to the vertical wall portions 24c2 and 24d2 of the above, the contact surface support portions 22c2 and 22d2 are arranged in the vertical direction of the vehicle from the contact surface portion 22a to exchange heat when they come into contact with the heat exchanger 3. It is possible to maintain that the contact surface portion 22a faces the vessel 3.
当接面支持部２２ｃ２，２２ｄ２から上下の縦壁部２４ｃ２，２４ｄ２に連結される上下の湾曲部２３ｃ２，２３ｄ２は、下部側の湾曲部２３ｄ２の長さを長く形成し、下部側の前記荷重吸収部Ａ２を、上部側の前記荷重吸収部Ａ１よりも脆弱に構成したので、荷重が作用した場合の折れの起点になるように制御することができる。 The upper and lower curved portions 23c2, 23d2 connected from the contact surface support portion 22c2, 22d2 to the upper and lower vertical wall portions 24c2, 24d2 form a long length of the lower curved portion 23d2, and absorb the load on the lower side. Since the portion A2 is configured to be weaker than the load absorbing portion A1 on the upper side, it can be controlled so as to be a starting point of breakage when a load is applied.
前記延出壁部２２の前方側の前記エアガイド本体部２１には切欠孔２０ａが設けられ、前記当接面部２２ａは前記切欠孔２０ａ側に位置するように設けられ、かつ前記延出壁部２２の当接面支持部２２ｃ２，２２ｄ２側には切欠孔２０ａ１，２０ａ２が設けられているので、湾曲部２３ｃ２，２３ｄ２および縦壁部２４ｃ２，２４ｄ２が脆弱部となることから、荷重が集中した時の折れの起点となることができる。 The air guide main body 21 on the front side of the extending wall portion 22 is provided with a notch hole 20a, the contact surface portion 22a is provided so as to be located on the notch hole 20a side, and the extending wall portion is provided. Since the cutout holes 20a1 and 20a2 are provided on the contact surface support portions 22c2 and 22d2 side of the 22 and the curved portions 23c2 and 23d2 and the vertical wall portions 24c2 and 24d2 become fragile portions, when the load is concentrated. It can be the starting point of the break.
本発明は、上記実施の形態のみに限定されるものではなく、例えば、エアガイド２の延出壁部２２はエアガイド本体部２１に１箇所のみに設けたが複数個所に設けることもできる。また、エアガイド本体部２としては、樹脂成形により成形してもよく、アルミニウム等の軽量金属等を用いてもよい。荷重吸収部Ａとしては、一体成形によって成形してもよく、別体によって成形してもよい。等、その他本発明の技術的範囲を変更しない範囲内で適宜変更して実施しうることは言うまでもない。 The present invention is not limited to the above embodiment. For example, the extending wall portion 22 of the air guide 2 is provided at only one location on the air guide main body portion 21, but may be provided at a plurality of locations. Further, the air guide main body 2 may be molded by resin molding, or a lightweight metal such as aluminum may be used. The load absorbing portion A may be integrally molded or may be molded separately. It goes without saying that the present invention can be appropriately modified and implemented without changing the technical scope of the present invention.
