The design member 30 has a base portion 31 for covering and hiding a vehicle body panel between the design member 30 and the rear quarter window 9 on the side surface of the vehicle body rear part, and a fillet portion 32 which projects out rearward from the base portion 31, and has a shape raised and opposed to lower surfaces of vehicle width direction both end portions of the spoiler portion 18.

Description

この発明は、車体後部構造に関し、詳しくは、車体後部の荷室開口部を上下方向に開閉し、上端部に車幅方向にわたって後方に突出するスポイラ部とその下方のバックウインドウを含むリフトゲートを有し、当該リフトゲートと車体後部側面のリヤクオータウインドウとの間に、車体とは別体に形成され車体外表面をなす意匠部材を介在させたような車体後部構造に関する。 The present invention relates to a vehicle body rear structure, and more specifically, a lift gate including a spoiler portion that opens and closes a cargo compartment opening at the rear of the vehicle body in the vertical direction and protrudes rearward in the vehicle width direction at the upper end portion and a back window below the spoiler portion. The present invention relates to a vehicle body rear structure in which a design member formed separately from the vehicle body and forming the vehicle body outer surface is interposed between the lift gate and a rear quarter window on the vehicle body rear side surface.

従来より、車両の空力特性の向上を目的として、車両後部にリヤスポイラを取付けることが知られており、例えば、リフトゲートを備えた車両においては、車体後部の荷室開口部を上下方向に開閉する当該リフトゲートの上端部に対して、車幅方向に延びるリヤスポイラが取付けられることになる。 Conventionally, it has been known to install a rear spoiler at the rear of the vehicle for the purpose of improving the aerodynamic characteristics of the vehicle. For example, in a vehicle equipped with a lift gate, the cargo compartment opening at the rear of the vehicle body is opened and closed vertically. A rear spoiler extending in the vehicle width direction is attached to the upper end portion of the lift gate.

このようなリヤスポイラを含むリフトゲートを有する従来の車体後部構造を図５，図６に示す。
図５は従来の車体後部構造を示す斜視図、図６は図５のＢ−Ｂ線矢視断面図である。
図５，図６に示すように、リフトゲートアウタパネル５１、リフトゲートインナパネル５２およびバックウインドウ５３を備えたリフトゲート５４を設け、このリフトゲート５４で車体後部の荷室開口部を上下方向に開閉するように構成している。 5 and 6 show a conventional rear body structure having a lift gate including such a rear spoiler.
FIG. 5 is a perspective view showing a conventional rear structure of the vehicle body, and FIG. 6 is a cross-sectional view taken along line BB in FIG.
As shown in FIGS. 5 and 6, a lift gate 54 having a lift gate outer panel 51, a lift gate inner panel 52, and a back window 53 is provided, and the lift gate 54 opens and closes the cargo compartment opening at the rear of the vehicle body in the vertical direction. It is configured to do.

そして、上述のリフトゲート５４の上端部には、車幅方向にわたって後方に突出するリヤスポイラ５５を取付け、このリヤスポイラ５５により車両の空力特性向上を図っている。
さらに、上述のリフトゲート５４側においてリヤスポイラ５５の車幅方向端部かつ当該リヤスポイラ５５の下部には、車体側面風を剥離させる作用を奏する略三角形状のフィレット部５６が設けられている。 A rear spoiler 55 that protrudes rearward in the vehicle width direction is attached to the upper end portion of the lift gate 54 described above, and the aerodynamic characteristics of the vehicle are improved by the rear spoiler 55.
Further, a substantially triangular fillet portion 56 is provided at the end of the rear spoiler 55 in the vehicle width direction and on the lower portion of the rear spoiler 55 on the lift gate 54 side.

このフィレット部５６の車幅方向外側に位置する外面部５６ａは、図６に示すように、リヤクオータウインドウ５７およびリヤピラー５８のリヤピラーアウタパネル５９と車両前後方向に滑らかに連続するように形成されており、走行風のうち車体側面風をフィレット部５６の後端部５６ｂで剥離して、空力性能の向上を図るように構成している。
上述のフィレット部をリヤスポイラと一体に形成すると、リヤスポイラそれ自体が大型化し、見栄えも悪化するので、図５，図６に示す従来構造では、フィレット部５６をリヤスポイラ５５と別体で形成している。 As shown in FIG. 6, the outer surface portion 56a located on the outer side in the vehicle width direction of the fillet portion 56 is formed so as to be smoothly continuous in the vehicle front-rear direction with the rear quarter window 57 and the rear pillar outer panel 59 of the rear pillar 58. The vehicle body side wind of the traveling wind is separated at the rear end portion 56b of the fillet portion 56 to improve the aerodynamic performance.
If the above-mentioned fillet part is formed integrally with the rear spoiler, the rear spoiler itself is enlarged and the appearance is deteriorated. In the conventional structure shown in FIGS. 5 and 6, the fillet part 56 is formed separately from the rear spoiler 55. .

ところで、リフトゲートの車幅方向の寸法との関係で、リフトゲートの車幅方向両サイド部と車体との間のパーティングラインが車体後面内側寄りに設定されると、リフトゲートの車幅方向全幅が小さくなり、リフトゲートの車幅方向全幅のリヤスポイラで良好な空力性能を確保することが困難となる。 By the way, if the parting line between the both sides of the lift gate in the vehicle width direction and the vehicle body is set closer to the inside of the rear surface of the vehicle body in relation to the dimensions of the lift gate in the vehicle width direction, The overall width becomes small, and it becomes difficult to ensure good aerodynamic performance with the rear spoiler of the full width of the lift gate in the vehicle width direction.

これを解決するためには、リヤスポイラを車両の略車幅方向全幅にわたって設けることが考えられるが、この場合には、リヤスポイラはパーティングラインから車幅方向外側にオーバハングすることになる。
リヤスポイラをオーバハングさせた状態で該リヤスポイラに対して、車体側面風を剥離させるフィレット部を、一体に垂下形成した場合には、フィレット部がリヤスポイラの車幅方向端部から大きく下方に垂れ下がって、見栄えが著しく悪化するのみならず、リヤスポイラは当然リフトゲートに設けられており、該リフトゲートは車体後部の荷室開口部を上下方向に開閉するものであるから、オーバハングしたリヤスポイラは、車体との関係上、高精度が要求されるので、フィレット部を含むリヤスポイラの製作性上の難点がある。 In order to solve this, it is conceivable to provide the rear spoiler over the entire width in the vehicle width direction of the vehicle. In this case, the rear spoiler overhangs from the parting line to the outside in the vehicle width direction.
When the fillet part that separates the vehicle body side wind from the rear spoiler with the rear spoiler overhanged is integrally suspended, the fillet part hangs down greatly from the end of the rear spoiler in the vehicle width direction and looks good. The rear spoiler is naturally provided at the lift gate, and the lift gate opens and closes the cargo compartment opening at the rear of the vehicle body. Therefore, the overhanged rear spoiler is related to the vehicle body. In addition, since high accuracy is required, there is a difficulty in manufacturability of the rear spoiler including the fillet portion.

一方で、特許文献１には、リフトゲートの上端部に車幅方向に延びるリヤスポイラを設けると共に、バックウインドウの車幅方向側端部に隣接するリヤピラーガーニッシュに、車体側面風の剥離用突起を複数設けたものが開示されているが、この特許文献１には、リヤスポイラのオーバハング部とフィレット部との協働についての技術思想が全くないものである。 On the other hand, in Patent Document 1, a rear spoiler extending in the vehicle width direction is provided at the upper end portion of the lift gate, and a plurality of protrusions for peeling the vehicle side wind are provided on the rear pillar garnish adjacent to the vehicle width direction end portion of the back window. Although what is provided is disclosed, this Patent Document 1 does not have any technical idea about the cooperation between the overhang portion and the fillet portion of the rear spoiler.
