図１（ａ）はインテークマニホールドを例示する側面図であり、図１（ｂ）はインテークマニホールドを例示する正面図である。1A is a side view illustrating the intake manifold, and FIG. 1B is a front view illustrating the intake manifold.

（第１実施形態）
以下、図面を参照して本実施形態のインテークマニホールド１００について説明する。図１（ａ）はインテークマニホールド１００を例示する側面図であり、図１（ｂ）はインテークマニホールド１００を例示する正面図である。図１（ａ）および図１（ｂ）に示すＸ軸方向は車両の前方向（Ｆｒ側）であり、Ｙ軸方向は上方向である。 (First embodiment)
Hereinafter, the intake manifold 100 of the present embodiment will be described with reference to the drawings. 1A is a side view illustrating the intake manifold 100, and FIG. 1B is a front view illustrating the intake manifold 100. The X-axis direction shown in FIGS. 1A and 1B is the front direction (Fr side) of the vehicle, and the Y-axis direction is the upward direction.

インテークマニホールド１００は自動車などの車両に搭載される。図１（ａ）に示すように、インテークマニホールド１００は３つのピース１０、１２および１４を接合することで形成されている。ピース１０、１２および１４はそれぞれ樹脂製である。ピース１０はインテークマニホールド１００のＦｒ側の壁を構成する。 Intake manifold 100 is mounted on a vehicle such as an automobile. As shown in FIG. 1A, the intake manifold 100 is formed by joining three pieces 10, 12 and 14. Each of the pieces 10, 12 and 14 is made of resin. The piece 10 constitutes a wall on the Fr side of the intake manifold 100.

図１（ｂ）に示すように、インテークマニホールド１００は複数の吸気管１５ａ〜１５ｃを有し、図１（ａ）に示すようにサージタンク１６、ＥＧＲ（Exhaust Gas Recirculation）トーナメント部１８、およびフランジ部２０（取付部）を有する。 As shown in FIG. 1(b), the intake manifold 100 has a plurality of intake pipes 15a to 15c, and as shown in FIG. 1(a), a surge tank 16, an EGR (Exhaust Gas Recirculation) tournament portion 18, and a flange. It has a part 20 (mounting part).

サージタンク１６およびＥＧＲトーナメント部１８は吸気管１５ａ〜１５ｃに連通する。フランジ部２０は各吸気管の先端であって、インテークマニホールド１００の−Ｘ側（Ｒｒ側）に位置する。フランジ部２０は不図示の内燃機関の吸気ポートに取り付けられる。吸気はサージタンク１６に一時的に溜められ、インテークマニホールド１００を流れ、フランジ部２０から内燃機関に供給される。 The surge tank 16 and the EGR tournament portion 18 communicate with the intake pipes 15a to 15c. The flange portion 20 is the tip of each intake pipe and is located on the −X side (Rr side) of the intake manifold 100. The flange portion 20 is attached to an intake port of an internal combustion engine (not shown). The intake air is temporarily stored in the surge tank 16, flows through the intake manifold 100, and is supplied from the flange portion 20 to the internal combustion engine.

図１（ａ）および図１（ｂ）に示すように、インテークマニホールド１００のＦｒ側の壁面であって、サージタンク１６とＥＧＲトーナメント部１８との間に厚肉部２２が形成されている。厚肉部２２は例えばピース１０と同一の樹脂から形成され、リブ２２ａおよび２２ｂを含む。図１（ｂ）に示すように、リブ２２ａは吸気管１５ａ〜１５ｃを横断し、図１（ａ）に示すように庇形状であり、壁面からＦｒ側に突出する。リブ２２ｂは吸気管ごとに設けられ、リブ２２ａと吸気管の壁面とを接続する。リブ２２ａの厚さＴはインテークマニホールド１００のＦｒ側の壁よりも大きく、厚さの差は例えば１ｍｍ以下でもよいし、１ｍｍ以上でもよい。このため厚肉部２２はインテークマニホールド１００の他の部分よりも高い剛性を有する。 As shown in FIGS. 1A and 1B, a thick wall portion 22 is formed between the surge tank 16 and the EGR tournament portion 18 on the Fr side wall surface of the intake manifold 100. The thick portion 22 is formed of, for example, the same resin as the piece 10 and includes ribs 22a and 22b. As shown in FIG. 1B, the rib 22a traverses the intake pipes 15a to 15c, has an eaves shape as shown in FIG. 1A, and projects from the wall surface to the Fr side. The rib 22b is provided for each intake pipe, and connects the rib 22a and the wall surface of the intake pipe. The thickness T of the rib 22a is larger than the wall on the Fr side of the intake manifold 100, and the difference in thickness may be 1 mm or less, or 1 mm or more. Therefore, the thick portion 22 has higher rigidity than other portions of the intake manifold 100.

内燃機関は例えばガソリンエンジンまたはディーゼルエンジンなどであり、燃料を燃焼することで動力を発生させる。燃料パイプ３０（燃料系部品）はフランジ部２０よりも上側（＋Ｙ側）に位置し、内燃機関に燃料を供給する。 The internal combustion engine is, for example, a gasoline engine or a diesel engine, and generates power by burning fuel. The fuel pipe 30 (fuel system component) is located above the flange portion 20 (+Y side) and supplies fuel to the internal combustion engine.

厚肉部２２は、フランジ部２０の燃料パイプ３０側とは反対側に位置する。すなわち、フランジ部２０の下端を通りフランジ部２０の延伸方向に沿う線分Ｌ１を挟んで、厚肉部２２は燃料パイプ３０の反対側に位置する。 The thick portion 22 is located on the opposite side of the flange portion 20 from the fuel pipe 30 side. That is, the thick portion 22 is located on the opposite side of the fuel pipe 30 with the line segment L1 that passes through the lower end of the flange portion 20 and extends along the extending direction of the flange portion 20.

車両のＦｒ側が他の車両などに衝突した際、インテークマニホールド１００は厚肉部２２の下から亀裂を生じ、破壊される。例えば図１（ａ）に示す厚肉部２２の下端を通る線分Ｌ２においてインテークマニホールド１００が破壊され、部分１００ａと部分１００ｂとに分割される。矢印で示すように線分Ｌ２より下の部分１００ｂは重力の作用で落下する。線分Ｌ２より上の部分１００ａは残存する。燃料パイプ３０は部分１０ａより後方側（−Ｘ側）に位置しており、部分１００ｂに接触しにくい。 When the Fr side of the vehicle collides with another vehicle or the like, the intake manifold 100 is cracked from below the thick portion 22 and is destroyed. For example, the intake manifold 100 is broken at a line segment L2 passing through the lower end of the thick portion 22 shown in FIG. 1A, and is divided into a portion 100a and a portion 100b. As indicated by the arrow, the portion 100b below the line segment L2 falls due to the action of gravity. The portion 100a above the line segment L2 remains. The fuel pipe 30 is located on the rear side (−X side) of the portion 10a and is unlikely to come into contact with the portion 100b.

本実施形態によれば、インテークマニホールド１００は燃料パイプ３０よりもＦｒ側に位置し、Ｆｒ側の壁面に厚肉部２２を有する。車両のＦｒ側衝突時にインテークマニホールド１００は厚肉部２２の下から破壊され、部分１００ａと部分１００ｂとに分離する。これにより衝撃が吸収され、ピース１０、１２および１４の分離が抑制される。したがって剥離したピースが燃料パイプ３０に衝突することによる燃料パイプ３０の破壊が抑制される。また、下側の部分１００ｂは落下し、燃料パイプ３０に接触しにくい。この結果、燃料パイプ３０が保護される。 According to the present embodiment, the intake manifold 100 is located on the Fr side of the fuel pipe 30, and has the thick portion 22 on the wall surface on the Fr side. When the vehicle collides with the Fr side, the intake manifold 100 is broken from below the thick portion 22 and separated into a portion 100a and a portion 100b. This absorbs the shock and suppresses the separation of the pieces 10, 12 and 14. Therefore, breakage of the fuel pipe 30 due to the peeled pieces colliding with the fuel pipe 30 is suppressed. Further, the lower portion 100b falls and is hard to come into contact with the fuel pipe 30. As a result, the fuel pipe 30 is protected.

上側の部分１００ａは残存し、燃料パイプ３０のＦｒ側に位置する。このためＦｒ側から飛来する物体は部分１００ａに衝突し、燃料パイプ３０には衝突しにくい。すなわち燃料パイプ３０は部分１００ａにより保護される。 The upper portion 100a remains and is located on the Fr side of the fuel pipe 30. Therefore, an object flying from the Fr side collides with the portion 100a and is less likely to collide with the fuel pipe 30. That is, the fuel pipe 30 is protected by the portion 100a.

厚肉部２２は庇形状を有することが好ましい。これにより、厚肉部２２は高い強度を有し、厚肉部２２の下側は厚肉部２２より低い強度を有する。したがって衝突時に厚肉部２２より下側においてインテークマニホールド１００が割れて、部分１００ｂが脱落しやすくなる。厚肉部２２はリブ２２ａおよびリブ２２ｂを含むとしたが、他の形状でもよい。 The thick portion 22 preferably has an eaves shape. As a result, the thick portion 22 has high strength, and the lower side of the thick portion 22 has lower strength than the thick portion 22. Therefore, at the time of collision, the intake manifold 100 is cracked below the thick portion 22 and the portion 100b is likely to fall off. Although the thick portion 22 includes the rib 22a and the rib 22b, it may have another shape.

インテークマニホールド１００と一体に厚肉部２２を設ければよく、プロテクタなどを設けなくてよいため、車両の軽量化および低コスト化が可能となる。 Since it is sufficient to provide the thick portion 22 integrally with the intake manifold 100 and not to provide a protector or the like, the weight and cost of the vehicle can be reduced.

図１（ｂ）に示すように、インテークマニホールド１００は、３気筒エンジンに対応して３つの吸気管１５ａ〜１５ｃを有する。インテークマニホールド１００はエンジンの気筒の数に応じて、１つ、２つまたは４つ以上の吸気管を有してもよい。厚肉部２２は少なくとも１つの吸気管に設けられてもよいが、複数の吸気管を横断することが好ましい。インテークマニホールド１００が各吸気管の厚肉部２２の下側から割れることで、燃料パイプ３０が保護される。 As shown in FIG. 1B, the intake manifold 100 has three intake pipes 15a to 15c corresponding to a three-cylinder engine. The intake manifold 100 may have one, two, or four or more intake pipes depending on the number of cylinders of the engine. Although the thick portion 22 may be provided in at least one intake pipe, it preferably crosses a plurality of intake pipes. The fuel pipe 30 is protected by cracking the intake manifold 100 from the lower side of the thick portion 22 of each intake pipe.

厚肉部２２は、インテークマニホールド１００のうち最も車両前方側の部分よりも後方かつ上に位置する。これによりＦｒ側の衝突時に部分１００ａを残存させ、かつ部分１００ｂを脱落させることができる。なお、燃料パイプ３０以外に燃料ポンプなど他の燃料系部品が設けられてもよい。燃料系部品が保護され、燃料漏れが抑制される。 The thick portion 22 is located rearward and above the portion of the intake manifold 100 that is closest to the vehicle front side. This allows the portion 100a to remain at the time of collision on the Fr side and allows the portion 100b to drop off. In addition to the fuel pipe 30, other fuel system components such as a fuel pump may be provided. The fuel system parts are protected and fuel leakage is suppressed.

以上本発明の好ましい実施形態について詳述したが、本発明は係る特定の実施形態に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲内において、種々の変形・変更が可能である。 Although the preferred embodiments of the present invention have been described above in detail, the present invention is not limited to the specific embodiments, and various modifications and variations are possible within the scope of the gist of the present invention described in the claims.
