Description

本発明は、リヤサスペンション取付部材が車体アウタパネル部材と近接配置された自動車車体後部構造に関する。 The present invention relates to a rear structure of an automobile body in which a rear suspension mounting member is disposed close to a vehicle body outer panel member.

一般に、リヤサスペンション取付部材に入力される後輪からの突上げ荷重は、リヤサスペンション取付部材からリンフォースリヤピラー等の車体骨格部材に転嫁されるように構成される。このように、従来は車体骨格部が主な応力支持部材であった。それは、リヤサスペンション取付部材が接続される通常の車体骨格部材は車体アウタパネル部材とは隔離された位置に配設されているからである。そのような車体骨格部材を備えるものとして、下記特許文献１に開示されたものがある。
特開２００２−３３７７３６号公報（図１、図３参照） Generally, the rear load applied to the rear suspension mounting member from the rear wheel is transferred from the rear suspension mounting member to a vehicle body frame member such as a reinforcement rear pillar. Thus, conventionally, the vehicle body skeleton is the main stress support member. This is because the normal vehicle body frame member to which the rear suspension mounting member is connected is disposed at a position isolated from the vehicle body outer panel member. There exists what was disclosed by the following patent document 1 as what is provided with such a vehicle body frame member.
JP 2002-337736 A (see FIGS. 1 and 3)

前記特許文献１に開示された従来例のものは、図５に示すように、リヤピラーインナ１０３とピラーリンフォース１０５とで形成した閉断面部１０６が、剛性メンバのリヤホイールハウス１１１に繋がり、特に該閉断面部１０６がリヤホイールハウスアウタ１１３に形成した略箱形の剛性強化部１１４に連結して剛体結合としてある。このような構成によって、リヤサスペンション入力を前記閉断面部１０６がその軸線方向で受けることができて、リヤピラー１０１の倒れ変形を防止してバックドアの開閉性能を確実に保持させることが可能となった。 In the conventional example disclosed in Patent Document 1, as shown in FIG. 5, a closed cross-section portion 106 formed by a rear pillar inner 103 and a pillar reinforcement 105 is connected to a rear wheel house 111 of a rigid member. The closed cross-section portion 106 is connected to a substantially box-shaped rigidity reinforcing portion 114 formed in the rear wheel house outer 113 to form a rigid body connection. With such a configuration, the closed section 106 can receive the rear suspension input in the axial direction thereof, and the rear pillar 101 can be prevented from falling down and the opening / closing performance of the back door can be reliably maintained. It was.

しかしながら、このような従来のものにあって、リヤサスペンション取付部材の応力支持部材となる略箱形の剛性強化部１１４は、リヤピラーインナ１０３とピラーリンフォース１０５とで形成した閉断面部１０６で構成される車体骨格部材に接続されている、このため、走行条件によっては、閉断面部１０６で構成される車体骨格部材と車体アウタパネル部材との間に相対変位が発生し、トリム部材のきしみ音、ボディ部材の溶接点の亀裂等の要因となる虞れが生じた。 However, in such a conventional one, the substantially box-shaped rigidity enhancing portion 114 serving as a stress supporting member of the rear suspension mounting member is configured by a closed cross-sectional portion 106 formed by the rear pillar inner 103 and the pillar reinforcement 105. Therefore, depending on traveling conditions, a relative displacement occurs between the vehicle body frame member constituted by the closed cross section 106 and the vehicle body outer panel member, and the squeak noise of the trim member, There was a risk of causing a crack in the welding point of the body member.

そこで本発明は、このような従来の自動車車体後部構造の諸課題を解決して、特に丸みを帯びた造形の車両の特性を活かし、サスペンションからの入力荷重を効率的に吸収することを可能にして、きしみ音の発生や溶接点の亀裂等の発生の虞れのない自動車車体後部構造を提供することを目的とする。 Therefore, the present invention solves the problems of the conventional rear structure of the automobile body, and makes it possible to efficiently absorb the input load from the suspension by taking advantage of the characteristics of the rounded vehicle. Thus, an object of the present invention is to provide a rear structure of an automobile body that is free from the occurrence of squeak noise and the occurrence of cracks at weld points.

このため本発明は、リヤサスペンション取付部材が車体アウタパネル部材と近接配置された自動車車体後部構造において、前記リヤサスペンション取付部材と車体アウタパネル部材とが接合されたことを特徴とする。また本発明は、前記リヤサスペンション取付部材の立壁がリヤホイールエプロン部材の立壁とともに車体アウタパネル部材に接合されたことを特徴とする。また本発明は、前記車体アウタパネル部材の後端のバンパー分割面との接合面を斜め上方に傾斜させたことを特徴とする。また本発明は、前記リヤサスペンション取付部材の荷重を主として受ける車体骨格部材がやや前方に偏位して設けられたことを特徴とするもので、これらを課題解決のための手段とする。 Therefore, the present invention is characterized in that the rear suspension mounting member and the vehicle body outer panel member are joined to each other in the rear structure of the vehicle body in which the rear suspension mounting member is disposed in proximity to the vehicle body outer panel member. Further, the present invention is characterized in that the standing wall of the rear suspension mounting member is joined to the vehicle body outer panel member together with the standing wall of the rear wheel apron member. Further, the present invention is characterized in that the joint surface with the bumper dividing surface at the rear end of the vehicle body outer panel member is inclined obliquely upward. Further, the present invention is characterized in that a vehicle body skeleton member that mainly receives the load of the rear suspension mounting member is provided slightly deviated forward, and these are used as means for solving the problems.

本発明によれば、リヤサスペンション取付部材が車体アウタパネル部材と近接配置された自動車車体後部構造において、前記リヤサスペンション取付部材と車体アウタパネル部材とが接合されたことにより、リヤサスペンション取付部材に作用する後輪等からの突上げ荷重を、近接配置された車体アウタパネル部材との接合部を介して、通常のリンフォースリヤピラー等の車体骨格部材への転嫁に加えて、車体アウタパネル部材にも転嫁させて、広範囲に広がる車体アウタパネル部材へ効率的に分散させることができ、内外での相対変位を最小に抑制して、トリム部材のきしみ音、ボディ部材の溶接点の亀裂等の要因を排除できる。 According to the present invention, in the rear structure of the vehicle body in which the rear suspension mounting member is disposed in proximity to the vehicle body outer panel member, the rear suspension mounting member and the vehicle body outer panel member are joined to each other, thereby acting on the rear suspension mounting member. In addition to passing to the vehicle body skeleton member such as a normal reinforcement rear pillar via the joint with the vehicle body outer panel member arranged in proximity, the thrust load from the wheel etc. is also passed to the vehicle body outer panel member, It is possible to efficiently disperse the vehicle body outer panel member that spreads over a wide range, and to suppress the relative displacement inside and outside to the minimum, and to eliminate factors such as squeak noise of the trim member and cracks in the welding points of the body member.

また、前記リヤサスペンション取付部材の立壁がリヤホイールエプロン部材の立壁とともに車体アウタパネル部材に接合された場合は、近接配置された車体アウタパネル部材に対してリヤサスペンション取付部材の立壁を利用して容易に接合することができ、しかも、該立壁を経由して効果的にリヤサスペンション取付部材に作用する後輪等からの突上げ荷重を伝達することができる。さらに、前記車体アウタパネル部材の後端のバンパー分割面との接合面を斜め上方に傾斜させた場合は、上方へ向かう突上げ荷重をより効果的に車体アウタパネル部材全体に伝達させることが可能となる。 Further, when the standing wall of the rear suspension mounting member is joined to the vehicle body outer panel member together with the standing wall of the rear wheel apron member, the rear suspension mounting member can be easily joined to the vehicle body outer panel member arranged in proximity using the standing wall of the rear suspension mounting member. In addition, it is possible to transmit the thrust load from the rear wheel or the like that acts on the rear suspension mounting member effectively via the standing wall. Further, when the joint surface with the bumper dividing surface at the rear end of the vehicle body outer panel member is inclined obliquely upward, the upward thrusting load can be more effectively transmitted to the entire vehicle body outer panel member. .

さらにまた、前記リヤサスペンション取付部材の荷重を主として受ける車体骨格部材がやや前方に偏位して設けられた場合は、２ドアタイプのように比較的リヤピラー部を広く採れる車両における車体骨格部材の配置の自由度を確保しつつ、リヤサスペンション取付部材の車体骨格部材との接続部とリヤサスペンション取付部材の車体アウタパネル部材との接続部間が離れて構成された場合でも、リヤサスペンション取付部材の突上げ荷重を車体アウタパネル部材への接続部を介しても効率的に分散させて伝達することができる。 Furthermore, when the vehicle body skeleton member that mainly receives the load of the rear suspension mounting member is provided slightly deviated forward, the arrangement of the vehicle body skeleton member in a vehicle having a relatively wide rear pillar portion such as a two-door type. Even when the connection portion between the rear suspension mounting member and the vehicle body skeleton member is separated from the connection portion between the rear suspension mounting member and the vehicle body outer panel member, the rear suspension mounting member is pushed up. The load can also be efficiently distributed and transmitted via the connecting portion to the vehicle body outer panel member.

以下、本発明の実施例を図面に基づいて説明する。図１は本発明の自動車車体後部構造の１つの実施例を示すもので、図１（Ａ）は要部の概略平断面図（図１（Ｂ）のＢ−Ｂ断面図）、図１（Ｂ）は自動車車体後部の概略側面図、図２は図１（Ａ）のＣ矢視の室内側から見た詳細斜視図、図３は図１（Ｂ）に相当する車体内部を示す詳細側面図（図４のＤの矢視図）、図４は図１（Ａ）に相当する要部の詳細平断面図である。本発明の自動車車体後部構造の基本的な構成は、図１に示すように、リヤサスペンション取付部材１が車体アウタパネル部材２と近接配置された自動車車体後部構造において、前記リヤサスペンション取付部材１と車体アウタパネル部材２とが接合されたことを特徴とする。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows one embodiment of the rear structure of an automobile body of the present invention. FIG. 1 (A) is a schematic plan sectional view (BB sectional view of FIG. 1 (B)) and FIG. B) is a schematic side view of the rear part of the vehicle body, FIG. 2 is a detailed perspective view as seen from the room side in the direction of arrow C in FIG. 1 (A), and FIG. FIG. 4 is a detailed plan sectional view of the main part corresponding to FIG. 1A. As shown in FIG. 1, the basic structure of the rear structure of an automobile body according to the present invention is an automobile body rear structure in which a rear suspension mounting member 1 is disposed in close proximity to a vehicle body outer panel member 2. The outer panel member 2 is joined.

実施例を以下に詳述する。図１（Ｂ）に示すように、本発明の自動車車体後部構造は、２ドアハッチバックタイプのように、ややリヤピラーの前後幅を比較的大きく採れる後部構造に適用される。そして、後部バックドアの側面シルエットは幾分丸みを有している。このように車体後端部の側面シルエットが丸みを帯びていることによって、図１（Ａ）に示すように、車体アウタパネル部材２をリヤサスペンション取付部材１に近接させて内側に寄せることが可能である。したがって、その分相対的にリヤバンパー４の範囲が拡大される。 Examples will be described in detail below. As shown in FIG. 1B, the vehicle body rear structure of the present invention is applied to a rear structure in which the rear pillar can have a relatively large front-rear width, such as a two-door hatchback type. And the side silhouette of the rear back door is somewhat rounded. Since the side silhouette of the rear end of the vehicle body is rounded as described above, the vehicle body outer panel member 2 can be brought close to the rear suspension mounting member 1 and moved inward as shown in FIG. is there. Accordingly, the range of the rear bumper 4 is relatively enlarged accordingly.

図１（Ａ）にてよく理解されるように、リヤサスペンション取付部材１と該取付部材１に近接配置された車体アウタパネル部材２とがＰ部にて接合される。また、前記リヤサスペンション取付部材１の荷重を主として受けるリンフォースリヤピラー等の車体骨格部材３がやや前方に偏位して設けられている。特に、このような２ドアタイプでは比較的リヤピラー部を広く採れる車両における車体骨格部材の配置の自由度を確保しつつ、リヤサスペンション取付部材１の車体骨格部材３との接続部とリヤサスペンション取付部材１の車体アウタパネル部材２との接続部間が離れて構成された場合でも、リヤサスペンション取付部材１の突上げ荷重を車体アウタパネル部材２への接続部Ｐ部を介しても効率的に分散させて伝達することができる。点線の符号４は、車体アウタパネル部材２をリヤサスペンション取付部材１に近接させて内側に寄せて配置できた分だけ範囲が拡大されたリヤバンパーを示すものである。 As is well understood in FIG. 1A, the rear suspension mounting member 1 and the vehicle body outer panel member 2 disposed in proximity to the mounting member 1 are joined at the P portion. Further, a vehicle body frame member 3 such as a reinforcement rear pillar that mainly receives the load of the rear suspension mounting member 1 is provided slightly deviated forward. In particular, in such a two-door type, the rear suspension mounting member 1 and the connection portion of the rear suspension mounting member 1 to the vehicle body frame member 3 and the rear suspension mounting member are secured while ensuring the degree of freedom of arrangement of the vehicle body frame member in a vehicle having a relatively wide rear pillar. Even in the case where the connection portions between the vehicle body outer panel member 2 and the vehicle body outer panel member 2 are separated from each other, the thrust load of the rear suspension mounting member 1 can be efficiently dispersed even through the connection portion P portion to the vehicle body outer panel member 2. Can communicate. A dotted line 4 indicates a rear bumper whose range is expanded by the amount that the vehicle body outer panel member 2 can be arranged close to the rear suspension mounting member 1 and moved inward.

図１（Ｂ）にてよく理解されるように、範囲が拡大されたリヤバンパー４は比較的大きな構造を有しており、好適には、車体アウタパネル部材２の後端のバンパー分割面との接合面Ｑを斜め上方に傾斜させて構成される。リヤサスペンション取付部材１は、リヤサスペンションからの突上げ荷重等を受ける水平壁１Ｂと、該荷重の一部を車体アウタパネル部材２に転嫁・伝達する接合面であるＰ部を含む立壁１Ａ（図１（Ａ））とから構成される。 As is well understood in FIG. 1 (B), the rear bumper 4 having an enlarged range has a relatively large structure, and is preferably formed with a bumper dividing surface at the rear end of the vehicle body outer panel member 2. The joining surface Q is inclined obliquely upward. The rear suspension mounting member 1 includes a horizontal wall 1B that receives a thrust load from the rear suspension, and a vertical wall 1A that includes a P portion that is a joint surface that transfers and transmits part of the load to the vehicle body outer panel member 2 (FIG. 1). (A)).

図１（Ｂ）の白矢印のように、後輪を懸架するリヤサスペンションからの突上げ荷重等が下方から加わると、リヤサスペンション取付部材１の水平壁１Ｂにて該荷重を受けた後、車体アウタパネル部材２との接合面を構成する立壁１ＡのＰ部を経て、車体アウタパネル部材２の広範囲の面に分散されていく。特に、車体アウタパネル部材２の後端のバンパー分割面との接合面Ｑ部から点線矢印のように、車体アウタパネル部材２の上方に効果的に荷重が分散されていく。 As shown by the white arrow in FIG. 1B, when a thrust load or the like from the rear suspension that suspends the rear wheel is applied from below, after receiving the load at the horizontal wall 1B of the rear suspension mounting member 1, the vehicle body It is distributed over a wide range of surfaces of the vehicle body outer panel member 2 through the P portion of the standing wall 1A that constitutes the joint surface with the outer panel member 2. In particular, the load is effectively distributed above the vehicle body outer panel member 2 from the joint surface Q with the bumper dividing surface at the rear end of the vehicle body outer panel member 2 as indicated by a dotted arrow.

図２は図１（Ａ）のＣ矢視の室内側から見た詳細斜視図である。左リヤピラー部を室内側から見た詳細図で、太実線がリヤサスペンション取付部材１を、太一点鎖線が車体アウタパネル部材２を、また、太点線がリヤホイールエプロン部材５をそれぞれ示す。符号３がリヤピラー部に配設されるリンフォースリヤピラー等の車体骨格部材３を示している。この図でよく理解されるように、リヤサスペンション取付部材１とリヤホイールエプロン部材５とは、それぞれの立壁１Ａ、５Ａの一部が重合して、リンフォースリヤピラー等の車体骨格部材３のインナ等に接合されるとともに、ハッチングで示したＰ部において太一点鎖線で示した車体アウタパネル部材２に接合される。 FIG. 2 is a detailed perspective view seen from the room side as viewed in the direction of arrow C in FIG. In the detailed view of the left rear pillar portion as viewed from the indoor side, the thick solid line indicates the rear suspension mounting member 1, the thick dashed line indicates the vehicle body outer panel member 2, and the thick dotted line indicates the rear wheel apron member 5. Reference numeral 3 denotes a vehicle body frame member 3 such as a reinforcement rear pillar disposed in the rear pillar portion. As is well understood in this figure, the rear suspension mounting member 1 and the rear wheel apron member 5 are such that a part of each of the standing walls 1A and 5A is overlapped, and the inner body of the vehicle body frame member 3 such as a reinforcement rear pillar or the like. And is joined to the vehicle body outer panel member 2 indicated by a thick dashed line at a P portion indicated by hatching.

リヤサスペンション取付部材１における水平壁１Ｂに突上げ荷重Ｆが加わると、多くの荷重はリヤサスペンション取付部材１の立壁１Ａを介してリンフォースリヤピラー等の車体骨格部材３に伝達されていくが、一部の荷重は、前記車体アウタパネル部材２との接合面であるＰ部を経て、白矢印のようにバンパー分割面との接合面Ｑ部から車体アウタパネル部材２全体に分散されていく。このようにリヤサスペンション取付部材１に近接配置された車体アウタパネル部材２に対してリヤサスペンション取付部材１の立壁１Ａを利用して容易に接合することができ、しかも、該立壁１Ａを経由して効果的にリヤサスペンション取付部材１に作用する後輪等からの突上げ荷重を伝達・分散することができる。 When a thrust load F is applied to the horizontal wall 1B of the rear suspension mounting member 1, a large amount of load is transmitted to the vehicle body frame member 3 such as a reinforcement rear pillar through the standing wall 1A of the rear suspension mounting member 1. The load of the part is distributed over the entire vehicle body outer panel member 2 from the bonding surface Q portion with the bumper dividing surface as indicated by the white arrow through the P portion which is the bonding surface with the vehicle body outer panel member 2. Thus, it is possible to easily join the vehicle body outer panel member 2 disposed in the vicinity of the rear suspension mounting member 1 by using the standing wall 1A of the rear suspension mounting member 1, and also through the standing wall 1A. Thus, the thrust load from the rear wheel or the like acting on the rear suspension mounting member 1 can be transmitted and dispersed.

図３は図１（Ｂ）に相当する車体内部を示す詳細側面図（図４のＤの矢視図）である。図では車体アウタパネル部材２は太一点鎖線で示されており、該アウタパネル部材２の内側に配設されたリンフォースリヤピラー等の車体骨格部材３、太実線で示されたリヤサスペンション部材１、太点線で示されたリヤホイールエプロン部材５等が見られる。この図でも、リヤサスペンション取付部材１における水平壁１Ｂに突上げ荷重Ｆが加わると、多くの荷重はリヤサスペンション取付部材１の立壁１Ａを介してリンフォースリヤピラー等の車体骨格部材３に伝達されていくが、一部の荷重は、前記車体アウタパネル部材２との接合面であるＰ部（ハッチング部）を経て、白矢印のようにバンパー分割面との接合面Ｑ部から車体アウタパネル部材２全体に分散されていく。 FIG. 3 is a detailed side view (indicated by arrow D in FIG. 4) showing the inside of the vehicle body corresponding to FIG. In the figure, the vehicle body outer panel member 2 is indicated by a thick one-dot chain line, a vehicle body skeleton member 3 such as a reinforcement rear pillar disposed inside the outer panel member 2, a rear suspension member 1 indicated by a thick solid line, a thick dotted line. A rear wheel apron member 5 shown in FIG. Also in this figure, when a thrust load F is applied to the horizontal wall 1B of the rear suspension mounting member 1, a large amount of load is transmitted to the vehicle body frame member 3 such as a reinforcement rear pillar via the standing wall 1A of the rear suspension mounting member 1. However, a part of the load passes through the P portion (hatched portion) which is a joint surface with the vehicle body outer panel member 2 and the whole vehicle body outer panel member 2 from the joint surface Q portion with the bumper dividing surface as indicated by a white arrow. Will be distributed.

図４は図１（Ａ）（図１（Ｂ）のＢ−Ｂ断面図）に相当する要部の詳細平断面図である。太一点鎖線で示されたアウタパネル部材２の内側に配設された太実線で示されたリヤサスペンション部材１、太点線で示されたリヤホイールエプロン部材５等が見られる。この図でも、リヤサスペンション取付部材１における水平壁１Ｂに突上げ荷重Ｆ（紙面手前に）が加わると、多くの荷重はリヤサスペンション取付部材１の立壁１Ａを介してリンフォースリヤピラー等の車体骨格部材（図示省略）に伝達されていくが、一部の荷重は、前記車体アウタパネル部材２との接合面であるＰ部を経て、バンパー分割面との接合面Ｑ部から車体アウタパネル部材２全体に分散されていく。かくして、後輪を懸架するリヤサスペンションからのリヤサスペンション取付部材１に加わる突上げ荷重は、広範囲に広がる車体アウタパネル部材へ効率的に分散させることができ、内外での相対変位を最小に抑制して、トリム部材のきしみ音、ボディ部材の溶接点の亀裂等の要因を排除できる。 FIG. 4 is a detailed cross-sectional plan view of a main part corresponding to FIG. 1A (a cross-sectional view taken along line BB in FIG. 1B). A rear suspension member 1 indicated by a thick solid line, a rear wheel apron member 5 indicated by a thick dotted line, and the like disposed inside the outer panel member 2 indicated by a thick dashed line can be seen. Also in this figure, when a thrust load F (before the paper surface) is applied to the horizontal wall 1B of the rear suspension mounting member 1, a large amount of load is applied to the vehicle body frame member such as the reinforcement rear pillar via the standing wall 1A of the rear suspension mounting member 1. Although part of the load is transmitted to (not shown), a part of the load is distributed to the entire vehicle body outer panel member 2 from the bonding surface Q portion with the bumper dividing surface through the P portion which is the bonding surface with the vehicle body outer panel member 2. It will be done. Thus, the thrust load applied to the rear suspension mounting member 1 from the rear suspension that suspends the rear wheel can be efficiently distributed to the vehicle body outer panel member that spreads over a wide range, and relative displacement inside and outside is minimized. Further, it is possible to eliminate factors such as a squeak noise of the trim member and a crack at the weld point of the body member.
