Description

この発明は、ルーフパネル後端の雨樋部に設けられた左右一対のヒンジを介して上開き構造のリヤハッチが取付けられたハッチバック車両のような車体後部構造に関する。   The present invention relates to a rear structure of a vehicle body such as a hatchback vehicle to which a rear hatch having a top opening structure is attached via a pair of left and right hinges provided at a rain gutter portion at the rear end of a roof panel.

従来、上述例のハッチバック車両の車体後部構造としては、特許文献１、特許文献２に開示された構造が知られている。   Conventionally, the structures disclosed in Patent Document 1 and Patent Document 2 are known as the rear body structure of the hatchback vehicle of the above-described example.

前者の特許文献１に開示された構造は、ルーフパネル後端の雨樋部に設けられた左右一対のヒンジを介して上開き構造のリヤハッチが取付けられたハッチバック車両において、ヒンジ位置を可及的高く設定し、室内高をかせぐ目的で、左右一対のヒンジが取付けられた部位にのみ対応して、ルーフパネルの後端部と、リヤハッチ上端のアウタパネルとを上方に膨出させて、左右の膨出部を形成し、これにより、ヒンジ位置を高く設定して、ルーフパネル後端部の全体を高くすることなく、ヘッドクリアランスを確保したものである。   The former structure disclosed in Patent Document 1 allows the hinge position to be as much as possible in a hatchback vehicle in which a rear hatch having an upper opening structure is attached via a pair of left and right hinges provided at a rain gutter portion at the rear end of the roof panel. For the purpose of increasing the height of the room and increasing the room height, the rear end of the roof panel and the outer panel at the upper end of the rear hatch are bulged upward, corresponding to only the part where the pair of left and right hinges are attached. The protruding portion is formed, and thereby the hinge position is set high, and the head clearance is ensured without increasing the entire rear end portion of the roof panel.

しかし、この従来構造においては、ヒンジ位置に対応する左右の両部に上方に膨出する膨出部が形成されているので、見映えが悪化する問題点があった。
後者の特許文献２に開示された構造は、ルーフパネル後端の雨樋部に設けられた左右一対のヒンジを介して上開き構造のリヤハッチが取付けられたハッチバック車両において、ルーフパネル後端部から下方に立下がる雨樋部の縦壁部に、車両前方方向に膨出する凹形状（いわゆるネガ形状）を形成したものである。 However, in this conventional structure, since the bulging part which bulges upward is formed in both the left and right parts corresponding to the hinge position, there is a problem that the appearance is deteriorated.
The latter structure disclosed in Patent Document 2 is a hatchback vehicle in which a rear hatch having an upper opening structure is attached via a pair of left and right hinges provided at a rain gutter portion at the rear end of the roof panel. A concave shape (so-called negative shape) that bulges in the vehicle front direction is formed on the vertical wall portion of the rain gutter portion that falls downward.

すなわち、ルーフパネルは一般的に後面視で上方に突出する上凸の緩円弧形状に形成されていて、リヤハッチ上端部はその閉時においてルーフパネルの後端部と略一致する形状に形成されている。この場合、上述のヒンジが取付けられた左右両部においてヒンジ中心とリヤハッチ上端部とを結ぶ長さは、ヒンジ間のそれと比較して相対的に小さく、雨樋部の縦壁部に前方へ膨出する凹形状を設けなくても、リヤハッチ開閉時にリヤハッチ上端部（リヤハッチ上端エッジの軌跡）が縦壁部と干渉することはないが、左右のヒンジ間においてはルーフパネルおよびリヤハッチの上凸の緩円弧形状により、ルーフ中央部ほど左右のヒンジ中心を結ぶヒンジセンタとリヤハッチ上端部とを結ぶ長さが、ヒンジ取付け部のそれと比較して相対的に大きくなり、雨樋部の縦壁部に前方へ膨出する凹形状（いわゆるネガ形状）を形成しない限り、リヤハッチ開閉時にリヤハッチ上端部（リヤハッチ上端エッジの軌跡）が縦壁部と干渉することになる。   That is, the roof panel is generally formed in an upwardly convex gentle arc shape that protrudes upward in a rear view, and the rear hatch upper end is formed in a shape that substantially coincides with the rear end of the roof panel when closed. Yes. In this case, the length connecting the hinge center and the rear hatch upper end at both the left and right portions where the hinge is attached is relatively smaller than that between the hinges, and swells forward on the vertical wall of the rain gutter. Even if the concave shape is not provided, the upper part of the rear hatch (the locus of the upper edge of the rear hatch) does not interfere with the vertical wall when opening and closing the rear hatch. Due to the circular arc shape, the length connecting the hinge center connecting the left and right hinge centers and the rear hatch upper end becomes relatively larger as compared to that of the hinge mounting part at the center of the roof. Unless a concave shape (so-called negative shape) that bulges out is formed, the rear hatch upper end (the locus of the rear hatch upper edge) interferes with the vertical wall when the rear hatch is opened and closed.

この干渉を回避する目的で、上述の凹形状が雨樋の縦壁部に形成されているが、この凹形状を別途プレス加工する必要があり、ルーフパネルの成形コストが高くなる問題点があった。
実用新案登録第２５６００５６号公報 特開２００４−１６１１２８号公報 In order to avoid this interference, the concave shape described above is formed in the vertical wall portion of the rain gutter. However, this concave shape needs to be separately pressed, and there is a problem that the cost for forming the roof panel increases. It was.

The height of the roof rear center recessed portion 4 is changed from the front end portion 4a to the rear end portion as shown in FIGS. It is formed so as to gradually decrease toward 4b. In other words, the depth of the concave portion of the roof rear central concave portion 4 is formed so as to gradually become deeper from the front end portion 4a to the rear end portion 4b. The roof rear central concave portion 4 has a height of the roof basic shape α. It is formed so as to descend from the rear toward the rear.

また、上述のルーフ後方中央凹部４とその車幅方向の両端部との境界部ｘにおいて、車両の前後方向にわたる段差部２３が形成されている。この段差部２３はルーフ後方中央凹部４の凹部の深さに対応して、その前端部では上下方向の寸法が小さく、車両後方に行くに従って上下方向の寸法が次第に大となるように形成されると共に、図２、図６に示す如く、該段差部２３は境界部ｘに相当する車幅方向の外方が高く、車幅方向の内方が低くなる外高内低状のスラント形状に形成されている。   Further, a stepped portion 23 extending in the front-rear direction of the vehicle is formed at a boundary portion x between the roof rear center concave portion 4 and both ends in the vehicle width direction. The step portion 23 is formed so that the vertical dimension is small at the front end portion corresponding to the depth of the concave portion of the roof rear central concave portion 4, and the vertical dimension is gradually increased toward the rear of the vehicle. In addition, as shown in FIGS. 2 and 6, the step portion 23 is formed in a slant shape having an outer height, an inner height, and a lower shape that are higher in the vehicle width direction corresponding to the boundary portion x and lower in the vehicle width direction. Has been.

さらに、ルーフ後方中央凹部４の車幅方向中心部４ｃはその両側よりも低くなるように構成されている。この実施例では、ルーフ後方中央凹部４の車幅方向中心部４ｃは段差部２３の下端部ｙよりも低くなるように構成されている。   Further, the center portion 4c in the vehicle width direction of the roof rear center recessed portion 4 is configured to be lower than both sides thereof. In this embodiment, the center part 4 c in the vehicle width direction of the roof rear center recessed part 4 is configured to be lower than the lower end part y of the step part 23.

このように形成されたルーフ後方中央凹部４の後端部の高さに略一致する上述のリヤハッチ中央凹部２２は次のように構成されている。
すなわち、このリヤハッチ中央凹部２２の高さは、図２、図４、図５、図６、
図７に示すようにその前端部２２ａから後端部２２ｂにかけて漸次低くなるように形成されている。 The above-described rear hatch central concave portion 22 that substantially matches the height of the rear end portion of the roof rear central concave portion 4 formed in this manner is configured as follows.
That is, the height of the rear hatch central recess 22 is as shown in FIG. 2, FIG. 4, FIG. 5, FIG.
As shown in FIG. 7, it is formed so as to gradually become lower from the front end portion 22a to the rear end portion 22b.

また、上述のリヤハッチ中央凹部２２とその車幅方向左右の両肩部２０，２１との境界部ｍにおいて外高内低状に傾斜するスラント状の段差部２４が形成されている。
さらに、リヤハッチ中央凹部２２の車幅方向中心部２２ｃはその両側の段差部２４の下端部ｎよりも低くなるように構成されている。 In addition, a slant-like stepped portion 24 is formed which is inclined in an outer height, an inner height, and a lower shape at a boundary portion m between the rear hatch central concave portion 22 and the left and right shoulder portions 20, 21 in the vehicle width direction.
Further, the center part 22c in the vehicle width direction of the rear hatch central recessed part 22 is configured to be lower than the lower end part n of the step part 24 on both sides thereof.

要するに、リヤハッチ３の閉成時において、ルーフパネル２側のルーフ後方中央凹部４と、リヤハッチ３上端側のリヤハッチ中央凹部２２とが車両の前後方向に連続するように形成されたものである。   In short, when the rear hatch 3 is closed, the roof rear center concave portion 4 on the roof panel 2 side and the rear hatch central concave portion 22 on the upper end side of the rear hatch 3 are formed so as to be continuous in the longitudinal direction of the vehicle.

そして、図２、図４、図７に示すように、上述のリヤハッチ中央凹部２２を車幅方向に跨ぐリヤスポイラ２５が設けられ、このリヤスポイラ２５とリヤハッチ中央凹部２２との間には空気流路２６が形成されており、走行風を図４に矢印で示すように流通すべく構成している。   2, 4, and 7, a rear spoiler 25 is provided to straddle the rear hatch central recess 22 in the vehicle width direction, and an air flow path 26 is provided between the rear spoiler 25 and the rear hatch central recess 22. Is formed so that the traveling wind flows as shown by arrows in FIG.

図２に示すように、上述のリヤスポイラ２５は、リヤハッチ３の上端部の車幅方向外側部における両肩部２０，２１の高さと略連続するもので、このリヤスポイラ２５は図４に断面図で示すように、後方に光を放射する光源部としてのＬＥＤ２７と、その基板２８と、リヤスポイラ２５の下面部を構成し、基板２８を介してＬＥＤ２７を支持する基部としてのハウジング２９と、リヤスポイラ２５の上面部および後面部を構成する赤色透明体部としてのアウタレンズ３０とを備え、ＬＥＤ２７の光をアウタレンズ３０を通して後方に放射すべく構成している。   As shown in FIG. 2, the rear spoiler 25 described above is substantially continuous with the heights of the shoulders 20 and 21 at the outer side in the vehicle width direction of the upper end portion of the rear hatch 3, and this rear spoiler 25 is shown in a sectional view in FIG. As shown, the LED 27 as a light source unit that emits light rearward, its substrate 28, a lower surface portion of the rear spoiler 25, a housing 29 as a base that supports the LED 27 via the substrate 28, and the rear spoiler 25 And an outer lens 30 as a red transparent body portion constituting the upper surface portion and the rear surface portion, and configured to radiate light of the LED 27 through the outer lens 30 backward.

ここで、上述のＬＥＤ２７は図８に示すように、その複数個が基板２８に一列状に設けられており、この基板２８を介してリヤスポイラ２５内に収容されている。   Here, as shown in FIG. 8, a plurality of the LEDs 27 are provided in a row on the substrate 28, and are accommodated in the rear spoiler 25 via the substrate 28.

図７に分解斜視図で示すように、リヤスポイラ２５のハウジング２９はリヤハッチ３のアウタパネル１５と一体成形されている。上述の各ＬＥＤ２７に電源を供給するハーネス３１は図７に示すように、ハウジング２９に開口形成された孔部３２を介してリヤハッチ３側へ配設されて、この孔部３２はハーネスグロメット３３で閉塞される。また、アウタレンズ３０は複数のビス等の取付け部材３４を用いてハウジング２９乃至リヤハッチ中央凹部２２の段差部２４に取付けられる。   As shown in an exploded perspective view in FIG. 7, the housing 29 of the rear spoiler 25 is integrally formed with the outer panel 15 of the rear hatch 3. As shown in FIG. 7, the harness 31 for supplying power to each LED 27 is disposed on the rear hatch 3 side through a hole 32 formed in the housing 29. The hole 32 is a harness grommet 33. Blocked. The outer lens 30 is attached to the step portion 24 of the housing 29 or the rear hatch central recess 22 using a plurality of attachment members 34 such as screws.

ここで、上述のハウジング２９をリヤハッチ３のアウタパネル１５と一体形成する構造に代えて、各要素２７〜３１から成るリヤスポイラ２５をサブアセンブリし、このリヤスポイラ２５を、リヤハッチ３におけるリヤハッチ中央凹部２２の段差部２４に後付けする構造を採用してもよい。   Here, instead of the structure in which the housing 29 described above is integrally formed with the outer panel 15 of the rear hatch 3, a rear spoiler 25 composed of the elements 27 to 31 is sub-assembled, and the rear spoiler 25 is used as a step of the rear hatch central recess 22 in the rear hatch 3. A structure retrofitted to the portion 24 may be employed.

なお、図中、矢印Ｆは車両前方を示し、矢印Ｒは車両後方を示すものである。また、図３、図４において仮想線ｚは後席乗員の頭部を概略的に示すものである。さらに、図４においては本実施例の構造と、従来例の構造とを対比する目的で、従来構造のルーフパネルβ１、雨樋部の縦壁部において前方に膨出する凹形状β２、リヤハッチβ３をそれぞれ仮想線にて併記している。   In the figure, arrow F indicates the front of the vehicle, and arrow R indicates the rear of the vehicle. 3 and 4, the imaginary line z schematically shows the head of the rear passenger. Further, in FIG. 4, for the purpose of comparing the structure of the present embodiment with the structure of the conventional example, the roof panel β1 of the conventional structure, the concave shape β2 bulging forward in the vertical wall portion of the rain gutter, and the rear hatch β3 Are shown together with virtual lines.

このように上記実施例の車体後部構造は、ルーフパネル２の後端部の雨樋部５に設けた左右一対のヒンジ１４，１４を介して上開き構造のリヤハッチ３が取付けられたハッチバック車両１の車体後部構造であって、上記ルーフパネル２は車両前後方向全域にわたって後面視で上凸の緩円弧形状に形成されたルーフ基本形状αを備える一方、上記ルーフパネル２の後端部から前方に所定距離Ｌ内で、かつ上記左右一対のヒンジ１４，１４間において上記ルーフ基本形状αより低い位置に形成されたルーフ後方中央凹部４を備え、上記リヤハッチ３の上端部は、該リヤハッチ３の閉時にルーフパネル後端部のルーフ基本形状αの高さに略一致する両肩部２０，２１と、上記ルーフ後方中央凹部４の高さに略一致するリヤハッチ中央凹部２２とを備えたものである。   As described above, the vehicle body rear structure of the above-described embodiment is a hatchback vehicle 1 in which the rear hatch 3 having an upper opening structure is attached via a pair of left and right hinges 14, 14 provided in the rain gutter portion 5 at the rear end of the roof panel 2. The roof panel 2 is provided with a basic roof shape α formed in an upwardly convex gentle arc shape in the rear view over the entire vehicle longitudinal direction, and forward from the rear end of the roof panel 2. A roof rear central recess 4 is formed within a predetermined distance L and between the pair of left and right hinges 14 and 14 at a position lower than the roof basic shape α, and an upper end portion of the rear hatch 3 is closed by the rear hatch 3. Sometimes, both shoulder portions 20, 21 substantially matching the height of the roof basic shape α at the rear end of the roof panel, and a rear hatch center recess 22 substantially matching the height of the roof rear center recess 4 are provided. It is intended.

この構成によれば、ルーフパネル２は上記ルーフ基本形状αとルーフ後方中央凹部４とを備え、リヤハッチ３は両肩部２０，２１とリヤハッチ中央凹部２２とを備える。つまり、ルーフパネル２はヒンジ１４位置を含む車幅方向両側では基本形状α通りの上凸の緩円円弧形状を有し、ルーフパネル２の中央部のみ凸形状をなくして、ルーフ後方中央凹部４を形成したので、車室内ヘッドクリアランスの確保と、ルーフ外観の見映え向上との両立を図ることができる。つまり、車両側面視（図１参照）、車両後方斜視（図２参照）においてはルーフ後方中央凹部４の存在にもかかわらず、ルーフ基本形状αが支配的に見えるため上記効果が得られる。   According to this configuration, the roof panel 2 includes the roof basic shape α and the roof rear center concave portion 4, and the rear hatch 3 includes both shoulder portions 20 and 21 and the rear hatch central concave portion 22. That is, the roof panel 2 has an upwardly convex gentle circular arc shape of the basic shape α on both sides in the vehicle width direction including the position of the hinge 14, and only the central portion of the roof panel 2 has no convex shape, and the roof rear central concave portion 4. As a result, the vehicle interior head clearance can be secured and the appearance of the roof can be improved. That is, in the vehicle side view (see FIG. 1) and the vehicle rear perspective view (see FIG. 2), the roof basic shape α appears dominant regardless of the presence of the roof rear center concave portion 4, and thus the above-described effect can be obtained.

また、リヤハッチ３は両肩部２０，２１と、上述のルーフ後方中央凹部４の高さに略一致するリヤハッチ中央凹部２２とを備えているので、リヤハッチ３の開閉時における車幅方向中央部分のリヤハッチ上端エッジ部の軌跡が小さくなり、雨樋部５における縦壁部５ａ前方膨出形状（いわゆる凹状のネガ形状）の廃止が可能となる。   Further, since the rear hatch 3 includes both shoulder portions 20 and 21 and a rear hatch central concave portion 22 that substantially matches the height of the roof rear central concave portion 4 described above, the rear hatch 3 has a central portion in the vehicle width direction when the rear hatch 3 is opened and closed. The trajectory of the rear hatch upper end edge portion becomes small, and the bulging shape (so-called concave negative shape) in front of the vertical wall portion 5a in the rain gutter portion 5 can be eliminated.

しかも、上記雨樋部５の縦壁部５ａは、前方に膨出する凹形状を有さないものである。
換言すれば、雨樋部５の縦壁部５ａは、ルーフパネル２の後端部から真っ直ぐ下方に立下がるフラット形状を有するように構成されたものである。
この構成によれば、雨樋部５の凹状の前方膨出形状（いわゆるネガ形状）を廃止することができ、ルーフパネル２の成形の容易化と、ルーフパネル２の加工工程の低減と、コストダウンとの両立を図ることができる。 Moreover, the vertical wall portion 5a of the gutter portion 5 does not have a concave shape that bulges forward.
In other words, the vertical wall portion 5a of the rain gutter portion 5 is configured to have a flat shape that falls straight downward from the rear end portion of the roof panel 2.
According to this configuration, the concave forward bulging shape (so-called negative shape) of the rain gutter part 5 can be eliminated, the forming of the roof panel 2 is facilitated, the processing steps of the roof panel 2 are reduced, and the cost is reduced. A balance with down can be achieved.

また、上記リヤハッチ中央凹部２２の車幅方向中心部２２ｃの上端の高さは上記ヒンジ１４のヒンジセンタＨＣの高さ位置に対して略同等またはそれ以下に設定されたものである（図４参照）。   The height of the upper end of the center part 22c in the vehicle width direction of the rear hatch central recess 22 is set to be substantially equal to or less than the height position of the hinge center HC of the hinge 14 (see FIG. 4). ).

上述のヒンジセンタＨＣとは左右一対のヒンジ１４，１４のヒンジピン中心を車幅方向に結ぶ仮想ラインを意味する。
この構成によれば、リヤハッチ中央凹部２２の車幅方向中心部２２ｃの上端の高さを上述の如く設定したので、このリヤハッチ中央凹部２２の上端エッジ部の軌跡が確実に小さくなり、雨樋部５の縦壁部５ａにおける前方へ膨出する凹形状β２（図４の仮想線参照）を確実に廃止することができる。 The above-described hinge center HC means a virtual line that connects the hinge pin centers of the pair of left and right hinges 14 and 14 in the vehicle width direction.
According to this configuration, since the height of the upper end of the center portion 22c in the vehicle width direction of the rear hatch central concave portion 22 is set as described above, the locus of the upper edge portion of the rear hatch central concave portion 22 is reliably reduced, and the rain gutter portion The concave shape β2 (see the phantom line in FIG. 4) that bulges forward in the vertical wall portion 5a of 5 can be reliably abolished.

さらに、上記ルーフ後方中央凹部４とその両端部との境界部ｘにおいて前後方向にわたる段差部２３が形成されたものである。
この構成によれば、ルーフ後方中央凹部４の段差部２３がビードとして作用するので、ルーフ強度、ルーフ剛性の向上を図ることができる。
加えて、上記ルーフ後方中央凹部４および上記リヤハッチ中央凹部２２を、これらの車幅方向中心部４ｃ，２２ｃがその両側より低くなるように構成したものである。 Further, a step portion 23 extending in the front-rear direction is formed at a boundary portion x between the roof rear center concave portion 4 and both end portions thereof.
According to this configuration, the step portion 23 of the roof rear center concave portion 4 acts as a bead, and therefore, the roof strength and the roof rigidity can be improved.
In addition, the roof rear center recessed portion 4 and the rear hatch center recessed portion 22 are configured such that the vehicle width direction center portions 4c and 22c are lower than both sides thereof.

この構成によれば、段差部２３，２４のビード効果を残しつつ、該段差部２３，２４の上下寸法を可及的小さくすることができるので、段差部２３，２４におけるルーフパネル２の後端とリヤハッチ３の上端エッジ部との干渉を回避することができる。   According to this configuration, the vertical dimension of the stepped portions 23, 24 can be made as small as possible while leaving the bead effect of the stepped portions 23, 24. Therefore, the rear end of the roof panel 2 at the stepped portions 23, 24 And interference with the upper edge portion of the rear hatch 3 can be avoided.

また、上記リヤハッチ中央凹部２２を跨ぐスポイラ部（リヤスポイラ２５参照）が設けられ、該スポイラ部（リヤスポイラ２５）と上記リヤハッチ中央凹部２２との間に空気流路２６が形成されたものである。   Further, a spoiler portion (see rear spoiler 25) straddling the rear hatch central recess 22 is provided, and an air flow path 26 is formed between the spoiler portion (rear spoiler 25) and the rear hatch central recess 22.

この構成によれば、スポイラ部（リヤスポイラ２５）により空力性能の向上と外観の見映え向上との両立を図ることができる。すなわち、ハッチ上端部が、リヤハッチ中央凹部２２の存在にもかかわらず、車幅水平方向に連続した高さを形成して見える（図２参照）ため、上記効果が得られる。
さらに、上記リヤハッチ３は樹脂製のアウタパネル１５と、樹脂製のインナパネル１６とを備えたものである。
この構成によれば、リヤハッチ３の上述の両肩部２０，２１およびリヤハッチ中央凹部２２を樹脂により容易に成形すると共に、リヤハッチ３の造形およびレイアウトの自由度向上を図ることができる。 According to this configuration, the spoiler part (rear spoiler 25) can improve both aerodynamic performance and appearance appearance. That is, since the upper end of the hatch appears to form a continuous height in the horizontal direction of the vehicle width in spite of the presence of the rear hatch central recess 22 (see FIG. 2), the above effect can be obtained.
Further, the rear hatch 3 includes a resin outer panel 15 and a resin inner panel 16.
According to this configuration, the above-described shoulder portions 20 and 21 and the rear hatch central concave portion 22 of the rear hatch 3 can be easily formed of resin, and the degree of freedom in shaping and layout of the rear hatch 3 can be improved.

図９は車体後部構造の他の実施例を示す部分平面図（但し、リヤスポイラを除去した状態の図面）で、図５の実施例においてはリヤハッチ中央凹部２２の境界部ｍ，ｍが互に略平行となるように形成したが、図９に示すこの実施例では、リヤハッチ中央凹部２２およびその段差部２４，２４がルーフ後方中央凹部４およびその段差部２３，２３の延長線上に沿うように形成され、リヤハッチ中央凹部２２前端の左右の境界部ｍ，ｍの車幅方向間隔に対して、その後端の左右の境界部ｍ，ｍの車幅方向間隔が大になるように形成されたものである。   FIG. 9 is a partial plan view showing another embodiment of the vehicle body rear structure (however, with the rear spoiler removed). In the embodiment of FIG. 5, the boundary portions m and m of the rear hatch central recess 22 are substantially the same. In this embodiment shown in FIG. 9, the rear hatch central recess 22 and its stepped portions 24, 24 are formed along the extended line of the roof rear central recess 4 and the stepped portions 23, 23. The rear hatch central recess 22 is formed so that the distance in the vehicle width direction between the left and right boundary portions m and m at the front end is larger than the distance between the left and right boundary portions m and m in the vehicle width direction. is there.
