Description

本発明は、グリルとカバー部材との接続構造に関するものである。 The present invention relates to a connection structure between the grill and the cover member.

一般的にエンジンルームの内部にはラジエータが配置されており、ラジエータの前方には異物の侵入を防止すると共に車両の外観印象を形成するグリルが配置されている。通常、グリルの上壁部は、エンジンルームを開閉するフードの下方に配置されており、フードが閉じられている状態ではフードによって隠されている。このようなグリルの上壁部には、フードが開放された場合であってもエンジンルームの一部を覆って隠すカバー部材が接続される場合がある。このようなカバー部材とグリルの上壁部は締結部材によって締結されることにより接続されている。 Generally, a radiator is arranged inside the engine room, and a grill that prevents foreign matter from entering and forms an impression of the appearance of the vehicle is arranged in front of the radiator. Normally, the upper wall of the grill is located below the hood that opens and closes the engine compartment, and is hidden by the hood when the hood is closed. A cover member that covers and hides a part of the engine room may be connected to the upper wall portion of such a grill even when the hood is opened. Such a cover member and the upper wall portion of the grill are connected by being fastened by a fastening member.

ところで、フードを開閉可能とするために、閉鎖状態のフードの前端には僅かな隙間が設けられている。この隙間から雨水等がエンジンルーム内に侵入するため、一般的にカバー部材には液体を下方に排水するための貫通孔が設けられている。しかしながら、カバー部材に貫通孔が形成されていると、フードを開放した場合に貫通孔がユーザの目につき、意匠性が損なわれる。さらに、貫通孔によるカバー部材の強度の低下も懸念される。このため、カバー部材に排水用の貫通孔を設けることなく、フードの前端からカバー部材上に流れ込んだ液体をカバー部材の下方に排出可能とする構成が望まれている。 By the way, in order to open and close the hood, a slight gap is provided at the front end of the closed hood. Since rainwater or the like enters the engine room through this gap, the cover member is generally provided with a through hole for draining the liquid downward. However, if a through hole is formed in the cover member, the through hole will be noticed by the user when the hood is opened, and the design will be impaired. Further, there is a concern that the strength of the cover member may be reduced due to the through hole. Therefore, it is desired to have a configuration in which the liquid flowing from the front end of the hood onto the cover member can be discharged below the cover member without providing a through hole for drainage in the cover member.

本発明は、上述する問題点に鑑みてなされたもので、カバー部材に排水用の貫通孔を設けることなく液体をカバー部材の下方に案内可能なグリルとカバー部材との接続構造を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems, and provides a connection structure between a grill and a cover member capable of guiding a liquid below the cover member without providing a through hole for drainage in the cover member.

以下、図面を参照して、本発明に係る車両用のグリルとカバー部材との接続構造の一実施形態について説明する。 Hereinafter, an embodiment of a connection structure between the grill for a vehicle and a cover member according to the present invention will be described with reference to the drawings.

図１は、本実施形態のグリルとカバー部材との接続構造（以下、単に接続構造１と称する）を用いてラジエータグリル２（グリル）とカバー部材３とが接続された車両の前部拡大斜視図である。 FIG. 1 shows an enlarged front view of a vehicle in which the radiator grill 2 (grill) and the cover member 3 are connected by using the connection structure between the grill and the cover member of the present embodiment (hereinafter, simply referred to as the connection structure 1). It is a figure.

ラジエータグリル２は、車両の前面の中央部に設けられており、エンジンルームの内部に設けられたラジエータの前方に配置されている。ラジエータグリル２は、例えば樹脂の基体の表面にめっき処理が施された部材であり、不図示の車体フレームに対して固定されている。また、ラジエータグリル２は、エンジンルームの開閉を行うフードＨの前縁の下方に配置されており、フードＨが閉じられた状態にて外部から視認可能な意匠部２ａと、フードＨが閉じられた状態で外部から視認されない部分とを有している。本実施形態において、ラジエータグリル２は、フードＨが閉じられた状態で外部から視認されない部分として、意匠部２ａの裏面から車両後方に向けて延出すると共にフードＨが閉じられた状態で外部から視認されない部分のうち最も上部に配置された上壁部２ｂを有している。 The radiator grill 2 is provided in the central portion of the front surface of the vehicle, and is arranged in front of the radiator provided inside the engine room. The radiator grill 2 is, for example, a member in which the surface of a resin substrate is plated, and is fixed to a vehicle body frame (not shown). Further, the radiator grill 2 is arranged below the front edge of the hood H that opens and closes the engine room, and the design portion 2a that can be visually recognized from the outside and the hood H are closed when the hood H is closed. It has a part that is not visible from the outside in the state of being in the state. In the present embodiment, the radiator grill 2 extends from the back surface of the design portion 2a toward the rear of the vehicle as a portion that is not visible from the outside when the hood H is closed, and the hood H is closed from the outside. It has an upper wall portion 2b arranged at the uppermost part of the invisible portions.

上壁部２ｂは、車幅方向に延びて設けられており、カバー部材３が接続される部位である。図２（ａ）は、上壁部２ｂとカバー部材３との接続部分を拡大した平面図である。また、図２（ｂ）は、図２（ａ）のＡ−Ａ断面図である。これらの図に示すように、上壁部２ｂは、車幅方向に交互に配列された排水部２ｃとカバー締結部２ｄとを有している。 The upper wall portion 2b is provided so as to extend in the vehicle width direction, and is a portion to which the cover member 3 is connected. FIG. 2A is an enlarged plan view of the connection portion between the upper wall portion 2b and the cover member 3. 2 (b) is a cross-sectional view taken along the line AA of FIG. 2 (a). As shown in these figures, the upper wall portion 2b has drainage portions 2c and cover fastening portions 2d which are alternately arranged in the vehicle width direction.

排水部２ｃは、下方に窪んだ排水溝２ｅが設けられた部位である。この排水溝２ｅは、上壁部２ｂの意匠部２ａ側の端部から車両後方の端部（先端部２ｂ１）に至るまで設けられており、車両前方から車両後方に向けて雨水等の液体Ｘを流す流路を形成している。なお、上壁部２ｂの先端部２ｂ１は、車両の後方に向けられており、下方に対して液体Ｘが落下しても、下方の機材等に影響を与えない位置に配置されている。つまり、排水溝２ｅから排出された液体Ｘは、車両の他の機材に対して影響を与えない位置に落水される。 The drainage portion 2c is a portion provided with a drainage groove 2e recessed downward. The drainage groove 2e is provided from the end portion of the upper wall portion 2b on the design portion 2a side to the end portion (tip portion 2b1) at the rear of the vehicle, and the liquid X such as rainwater is provided from the front of the vehicle to the rear of the vehicle. A flow path is formed. The tip portion 2b1 of the upper wall portion 2b is directed to the rear of the vehicle, and is arranged at a position that does not affect the equipment or the like below even if the liquid X falls downward. That is, the liquid X discharged from the drainage ditch 2e is dropped to a position that does not affect other equipment of the vehicle.

また、図３は、図２（ａ）のＢ−Ｂ断面図である。図３に示すように、排水溝２ｅの底面２ｅ１は、上壁部２ｂの車両前方の端部から先端部２ｂ１に向かうに連れて下降するように傾斜されている。なお、本実施形態においては、後述するようにカバー部材３の縁部が上壁部２ｂに重ねて配置されており、平面視にてカバー部材３の先端部３ｂが平面視にて上壁部２ｂの先端部２ｂ１よりも車両の前方側（意匠部２ａ側）に配置されている。したがって、排水溝２ｅの底面２ｅ１は、カバー部材３の先端部３ｂから上壁部２ｂの先端部２ｂ１に向かうに連れて下降するように傾斜されている。このため、排水溝２ｅに流れ込んだ液体Ｘは、重力によって底面２ｅ１の傾斜に沿って排水溝２ｅの排出端（上壁部２ｂの先端部２ｂ１）に向けて案内される。 Further, FIG. 3 is a cross-sectional view taken along the line BB of FIG. 2A. As shown in FIG. 3, the bottom surface 2e1 of the drainage groove 2e is inclined so as to descend from the front end of the upper wall portion 2b toward the tip portion 2b1. In the present embodiment, as will be described later, the edge portion of the cover member 3 is arranged so as to overlap the upper wall portion 2b, and the tip portion 3b of the cover member 3 is arranged on the upper wall portion 2b in a plan view. It is arranged on the front side (design portion 2a side) of the vehicle from the tip portion 2b1 of 2b. Therefore, the bottom surface 2e1 of the drainage groove 2e is inclined so as to descend from the tip portion 3b of the cover member 3 toward the tip portion 2b1 of the upper wall portion 2b. Therefore, the liquid X that has flowed into the drainage groove 2e is guided by gravity toward the discharge end of the drainage groove 2e (the tip end portion 2b1 of the upper wall portion 2b) along the inclination of the bottom surface 2e1.

図４は、図２（ａ）のＣ−Ｃ断面図である。カバー締結部２ｄは、排水溝２ｅの上端と同一高さの上面を有しており、図４に示すように、この上面がカバー部材３の下面に当接させる部位である。このカバー締結部２ｄには、上下に貫通するねじ孔２ｄ１が形成されている。このねじ孔２ｄ１にねじ４が螺合されることによって、カバー締結部２ｄ（すなわちラジエータグリル２）がカバー部材３と締結される。 FIG. 4 is a sectional view taken along the line CC of FIG. 2 (a). The cover fastening portion 2d has an upper surface having the same height as the upper end of the drainage groove 2e, and as shown in FIG. 4, this upper surface is a portion that comes into contact with the lower surface of the cover member 3. A screw hole 2d1 that penetrates vertically is formed in the cover fastening portion 2d. By screwing the screw 4 into the screw hole 2d1, the cover fastening portion 2d (that is, the radiator grill 2) is fastened to the cover member 3.

なお、カバー締結部２ｄは、ラジエータグリル２とカバー部材３とが当接された領域である。また、排水溝２ｅは、平面視にてラジエータグリル２とカバー部材３とが重ねられた領域（重畳領域）にて、カバー締結部２ｄを避けて形成されている。つまり、本実施形態においては、重畳領域のうちラジエータグリル２とカバー部材３とが当接された領域を避けて排水溝２ｅが設けられている。 The cover fastening portion 2d is a region where the radiator grill 2 and the cover member 3 are in contact with each other. Further, the drainage groove 2e is formed in a region (overlapping region) where the radiator grill 2 and the cover member 3 are overlapped in a plan view, avoiding the cover fastening portion 2d. That is, in the present embodiment, the drainage groove 2e is provided so as to avoid the region where the radiator grill 2 and the cover member 3 are in contact with each other in the superposed region.

また、カバー締結部２ｄの下方には、上方に向かって窪んで設けられた下面凹部２ｆが設けられている。つまり、本実施形態においては、図２（ｂ）に示すように、下面凹部２ｆと排水溝２ｅとが車幅方向に並んで配置されている。このような下面凹部２ｆと排水溝２ｅとが車幅方向に交互に複数設けられることによって、ラジエータグリル２の上壁部２ｂは、車両の前後方向から見て波型形状とされている。このような上壁部２ｂは、車両の前後方向から見て、厚さ寸法が排水部２ｃとカバー締結部２ｄとで同一あるいは略同一とされている。 Further, below the cover fastening portion 2d, a lower surface recess 2f is provided that is recessed upward. That is, in the present embodiment, as shown in FIG. 2B, the lower surface recess 2f and the drainage groove 2e are arranged side by side in the vehicle width direction. By providing a plurality of such lower surface recesses 2f and drainage grooves 2e alternately in the vehicle width direction, the upper wall portion 2b of the radiator grill 2 has a corrugated shape when viewed from the front-rear direction of the vehicle. Such an upper wall portion 2b has the same or substantially the same thickness dimension in the drainage portion 2c and the cover fastening portion 2d when viewed from the front-rear direction of the vehicle.

カバー部材３は、エンジンルームの前方側の領域を覆うように配置されており、フードＨが閉鎖された状態でフードＨによって上方から覆われる部材である。このカバー部材３は、車両の前方側の縁部がラジエータグリル２の上壁部２ｂと接続されている。カバー部材３は、ラジエータグリル２の上壁部２ｂのカバー締結部２ｄの位置に合わせて上下に貫通するねじ挿通孔３ａが設けられている。このねじ挿通孔３ａは、平面視にて、カバー締結部２ｄに設けられたねじ孔２ｄ１に重なる位置に設けられている。図４に示すように、上壁部２ｂの上方にカバー部材３が重ねられ、ねじ４がねじ挿通孔３ａを挿通した状態でねじ孔２ｄ１に螺合されることによって、上壁部２ｂ（すなわちラジエータグリル２）とカバー部材３とが締結されている。 The cover member 3 is arranged so as to cover the area on the front side of the engine room, and is a member that is covered from above by the hood H in a state where the hood H is closed. The front edge of the cover member 3 is connected to the upper wall 2b of the radiator grill 2. The cover member 3 is provided with a screw insertion hole 3a that penetrates vertically in accordance with the position of the cover fastening portion 2d of the upper wall portion 2b of the radiator grill 2. The screw insertion hole 3a is provided at a position overlapping the screw hole 2d1 provided in the cover fastening portion 2d in a plan view. As shown in FIG. 4, the cover member 3 is superposed on the upper wall portion 2b, and the screw 4 is screwed into the screw hole 2d1 with the screw insertion hole 3a inserted, whereby the upper wall portion 2b (that is, that is, The radiator grill 2) and the cover member 3 are fastened.

また、カバー部材３の車両前方側の端部（先端部３ｂ）は、ラジエータグリル２の意匠部２ａと離間されており、カバー部材３とラジエータグリル２の意匠部２ａとの間に車両前後方向に空く隙間が設けられている。このため、図２（ａ）等に示されているように、排水溝２ｅの意匠部２ａ側の領域（一部領域）は、カバー部材３によって覆われていない。このようなカバー部材３の縁部は、本実施形態において、上面及び下面が凹凸のない滑らかな平面状とされている。 Further, the end portion (tip portion 3b) of the cover member 3 on the vehicle front side is separated from the design portion 2a of the radiator grill 2, and the vehicle front-rear direction is between the cover member 3 and the design portion 2a of the radiator grill 2. There is a gap in the space. Therefore, as shown in FIG. 2A and the like, the region (partial region) of the drainage groove 2e on the design portion 2a side is not covered by the cover member 3. In the present embodiment, the edge portion of such a cover member 3 has a smooth flat surface with no unevenness on the upper surface and the lower surface.

このような本実施形態の接続構造１によれば、例えばフードＨの前端から落下した液体Ｘは、図２に示すように、カバー部材３の先端部３ｂと意匠部２ａとの隙間から排水溝２ｅに流れ込み、排水溝２ｅに案内されてカバー部材３の下方を流れて上壁部２ｂの先端部２ｂ１から排水される。つまり、本実施形態においては、液体Ｘは、ラジエータグリル２の上壁部２ｂとカバー部材３との上下方向における境界部分から排水される。 According to the connection structure 1 of the present embodiment, for example, the liquid X that has fallen from the front end of the hood H is drained from the gap between the tip portion 3b of the cover member 3 and the design portion 2a, as shown in FIG. It flows into 2e, is guided by the drainage groove 2e, flows below the cover member 3, and is drained from the tip portion 2b1 of the upper wall portion 2b. That is, in the present embodiment, the liquid X is drained from the boundary portion in the vertical direction between the upper wall portion 2b of the radiator grill 2 and the cover member 3.

以上のような本実施形態の接続構造１においては、平面視にてラジエータグリル２の上壁部２ｂの一部にカバー部材３の縁部が上方から重ねて配置され、平面視におけるラジエータグリル２の上壁部２ｂとカバー部材３の縁部との重畳領域の一部にてラジエータグリル２とカバー部材３とが当接状態で締結され、重畳領域のうちラジエータグリル２とカバー部材３とが当接された領域を避けて上壁部２ｂの上面に平面視にてカバー部材３の先端部３ｂから上壁部２ｂの先端部２ｂ１に至る排水溝２ｅが設けられている。 In the connection structure 1 of the present embodiment as described above, the edge portion of the cover member 3 is arranged so as to overlap a part of the upper wall portion 2b of the radiator grill 2 from above in a plan view, and the radiator grill 2 in a plan view. The radiator grill 2 and the cover member 3 are fastened in contact with each other at a part of the overlapping region between the upper wall portion 2b and the edge portion of the cover member 3, and the radiator grill 2 and the cover member 3 are engaged in the overlapping region. A drainage groove 2e from the tip portion 3b of the cover member 3 to the tip portion 2b1 of the upper wall portion 2b is provided on the upper surface of the upper wall portion 2b while avoiding the contacted region.

このような本実施形態の接続構造１によれば、ラジエータグリル２の上壁部２ｂに対して上方からカバー部材３の縁部が重ねて配置され、上壁部２ｂの上面に平面視にてカバー部材３の先端部３ｂから上壁部２ｂの先端部２ｂ１に至る排水溝２ｅが設けられている。このため、ラジエータグリル２の上壁部２ｂとカバー部材３との境界部分から排水が可能となり、カバー部材３に排水のための貫通孔を設けることなく液体Ｘをカバー部材３の下方に案内することができる。 According to the connection structure 1 of the present embodiment as described above, the edge portion of the cover member 3 is arranged so as to overlap the upper wall portion 2b of the radiator grill 2 from above, and is arranged on the upper surface of the upper wall portion 2b in a plan view. A drainage groove 2e is provided from the tip portion 3b of the cover member 3 to the tip portion 2b1 of the upper wall portion 2b. Therefore, drainage is possible from the boundary portion between the upper wall portion 2b of the radiator grill 2 and the cover member 3, and the liquid X is guided below the cover member 3 without providing a through hole for drainage in the cover member 3. be able to.

また、本実施形態の接続構造１においては、ラジエータグリル２の上壁部２ｂに下方に窪んで排水溝２ｅが設けられている。このような本実施形態の接続構造１によれば、ラジエータグリル２の上壁部２ｂに溝を形成することで排水が可能であるため、カバー部材３に対して排水のための溝を形成する必要がない。このため、カバー部材３を異様な厚さ寸法としようとした場合に、カバー部材３の上面に凹凸を設ける必要がない。よって、本実施形態の接続構造１によれば、厚さ寸法が一様で上面が平面状のカバー部材３とすることができる。このように上面が平面状のカバー部材３とすることで、フードＨを開放した場合に視認されるカバー部材３の外観印象が向上すると共に、カバー部材３上の清掃等のメンテナンス作業が容易となる。 Further, in the connection structure 1 of the present embodiment, a drainage groove 2e is provided in the upper wall portion 2b of the radiator grill 2 by being recessed downward. According to the connection structure 1 of the present embodiment, drainage is possible by forming a groove in the upper wall portion 2b of the radiator grill 2, so that a groove for drainage is formed in the cover member 3. There is no need. Therefore, when the cover member 3 is intended to have an unusual thickness, it is not necessary to provide unevenness on the upper surface of the cover member 3. Therefore, according to the connection structure 1 of the present embodiment, the cover member 3 having a uniform thickness and a flat upper surface can be formed. By forming the cover member 3 having a flat upper surface in this way, the appearance impression of the cover member 3 that can be visually recognized when the hood H is opened is improved, and maintenance work such as cleaning on the cover member 3 is facilitated.

Therefore, according to the connection structure 1 of the present embodiment, the upper wall portion 2b of the radiator grill 2 has a wavy shape when viewed from the front-rear direction of the vehicle, and the thickness dimension is the drainage portion 2c and the cover fastening portion 2d. It is the same or almost the same. Therefore, when the cover member 3 is formed by injection molding, it is possible to prevent the cover member 3 from being unintentionally deformed due to sink marks or the like during cooling.

また、本実施形態の接続構造１においては、排水溝２ｅの底面２ｅ１がカバー部材３の先端部３ｂから上壁部２ｂの先端部２ｂ１に向かうに連れて下降するように傾斜されている。このため、本実施形態の接続構造１によれば、排水溝２ｅに流れ込んだ液体Ｘを確実に排水溝２ｅから排出することが可能となる。また、排水溝２ｅに流れ込んだ液体Ｘが逆流することを防止することが可能となる。 Further, in the connection structure 1 of the present embodiment, the bottom surface 2e1 of the drainage groove 2e is inclined so as to descend from the tip portion 3b of the cover member 3 toward the tip portion 2b1 of the upper wall portion 2b. Therefore, according to the connection structure 1 of the present embodiment, the liquid X that has flowed into the drainage groove 2e can be reliably discharged from the drainage groove 2e. Further, it is possible to prevent the liquid X that has flowed into the drainage groove 2e from flowing back.

また、本実施形態の接続構造１においては、平面視にて、ラジエータグリル２とカバー部材３とが当接された領域と排水溝２ｅとが交互に複数設けられている。つまり、本実施形態の接続構造１によれば、複数の排水溝２ｅが車幅方向に配列されて設けられている。このため、円滑に液体Ｘの排水を行うことが可能となる。 Further, in the connection structure 1 of the present embodiment, a plurality of regions where the radiator grill 2 and the cover member 3 are in contact with each other and a plurality of drainage grooves 2e are provided alternately in a plan view. That is, according to the connection structure 1 of the present embodiment, a plurality of drainage grooves 2e are provided so as to be arranged in the vehicle width direction. Therefore, the liquid X can be drained smoothly.

以上、添付図面を参照しながら本発明の好適な実施形態について説明したが、本発明は上記実施形態に限定されないことは言うまでもない。上述した実施形態において示した各構成部材の諸形状や組み合わせ等は一例であって、本発明の趣旨から逸脱しない範囲において設計要求等に基づき種々変更可能である。 Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above embodiment. The various shapes and combinations of the constituent members shown in the above-described embodiment are examples, and can be variously changed based on design requirements and the like without departing from the spirit of the present invention.

例えば、上記実施形態においては、ラジエータグリル２の上壁部２ｂに排水溝２ｅを形成する構成について説明した。しかしながら、本発明はこれに限定されるものではない。例えば、カバー部材３の下面に排水溝を設ける構成を採用することも可能である。または、ラジエータグリル２の上壁部２ｂと、カバー部材３との両方に排水溝２ｅを設ける構成を採用することも可能である。 For example, in the above embodiment, the configuration of forming the drainage groove 2e in the upper wall portion 2b of the radiator grill 2 has been described. However, the present invention is not limited to this. For example, it is possible to adopt a configuration in which a drainage groove is provided on the lower surface of the cover member 3. Alternatively, it is also possible to adopt a configuration in which the drainage groove 2e is provided in both the upper wall portion 2b of the radiator grill 2 and the cover member 3.

また、上記実施形態においては、上壁部２ｂが下面凹部２ｆを有することによって、上壁部２ｂが波型形状とされた構成について説明した。しかしながら、本発明はこれに限定されるものではなく、下面凹部２ｆを設けない構成を採用することも可能である。 Further, in the above-described embodiment, the configuration in which the upper wall portion 2b has a wavy shape by having the lower surface recess 2f has been described. However, the present invention is not limited to this, and it is also possible to adopt a configuration in which the lower surface recess 2f is not provided.

また、上記実施形態においては、排水溝２ｅの底面２ｅ１が傾斜した構成について説明した。しかしながら、本発明はこれに限定されるものではなく、底面２ｅ１が水平面とされた構成を採用することも可能である。 Further, in the above embodiment, the configuration in which the bottom surface 2e1 of the drainage groove 2e is inclined has been described. However, the present invention is not limited to this, and it is also possible to adopt a configuration in which the bottom surface 2e1 is a horizontal plane.

図５は、上記実施形態の接続構造１の変形例の模式的な断面図である。この図に示すように、排水溝２ｅの底面２ｅ１に、排水溝２ｅよりも幅寸法が小さい小幅流路２ｇを設けるようにしても良い。なお、小幅流路２ｇは、平面視にて少なくともカバー部材３の先端部３ｂから上壁部２ｂの先端部２ｂ１に至る範囲に設けられている。このような小幅流路２ｇを設けることによって、仮に排水溝２ｅが落ち葉等の異物で閉塞したとしても、小幅流路２ｇを介して、排水を行うことができる。 FIG. 5 is a schematic cross-sectional view of a modified example of the connection structure 1 of the above embodiment. As shown in this figure, a narrow flow path 2g having a width smaller than that of the drainage groove 2e may be provided on the bottom surface 2e1 of the drainage groove 2e. The narrow flow path 2g is provided in a range from at least the tip portion 3b of the cover member 3 to the tip portion 2b1 of the upper wall portion 2b in a plan view. By providing such a narrow flow path 2g, even if the drainage groove 2e is blocked by a foreign substance such as fallen leaves, drainage can be performed through the narrow flow path 2g.
