Description

本発明は、自動車の車体構造に関し、特に、フロントドアを含む車体側部構造に関する。   The present invention relates to a vehicle body structure of an automobile, and more particularly to a vehicle body side structure including a front door.

前部衝突対策をなされた自動車の車体構成には、下記のようなものが知られている。   The following are known body configurations of automobiles that have been subjected to front collision countermeasures.

フロントドアのインナパネルに、車体前後方向に延在するドアビーム部材が取り付けられ、前部衝突時の衝突荷重がドアビーム部材によって車体後方へ伝達されることにより、車体側部のフロントドア開口部の変形を抑制回避するもの（例えば、特許文献１）。   A door beam member extending in the longitudinal direction of the vehicle body is attached to the inner panel of the front door, and the collision load at the time of a frontal collision is transmitted to the rear of the vehicle body by the door beam member, thereby deforming the front door opening on the side of the vehicle body (For example, Patent Document 1).

閉断面形状のフロントピラーの内面にドアヒンジスチフナが取り付けられ、ドアヒンジスチフナによってフロントピラーに対するフロントドアヒンジの取付部の補強を行い、前部衝突時の衝突荷重がフロントドアヒンジ部分よりフロントドアへ伝達されるようにしたもの（例えば、特許文献２）。   A door hinge stiffener is attached to the inner surface of the front pillar with a closed cross-sectional shape, and the door hinge stiffener reinforces the mounting portion of the front door hinge with respect to the front pillar, so that the collision load at the time of front collision is transmitted from the front door hinge to the front door (For example, Patent Document 2).

フロントピラーより車体前方に延びるアッパメンバ（ホイールハウスアッパメンバ）がフロントピラーとの接続に加えて、ガセットプレートを用いてダシュボードアッパメンバの左右側部に接続され、アッパメンバのフロントピラー側の接続強度の向上を図ったもの（例えば、特許文献３）。   The upper member (wheel house upper member) that extends forward from the front pillar is connected to the left and right sides of the dashboard upper member using gusset plates in addition to the connection to the front pillar, improving the connection strength of the upper member on the front pillar side (For example, Patent Document 3).

フロントフェンダエプロンメンバのフロントピラーとの接続側に形成されたビードとフロントピラーとによってボックス断面形状部を設けることにより、フロントフェンダエプロンメンバとフロントピラーとの結合部の強度を高め、前部衝突時の衝突荷重がフロントフェンダエプロンメンバより上記結合部を経てフロントドアへ伝達されるようにしたもの（例えば、特許文献４）。   By providing a box cross-section with a bead and front pillar formed on the front fender apron member's connection side with the front pillar, the strength of the joint between the front fender apron member and the front pillar is increased, and a front collision occurs. The impact load is transmitted from the front fender apron member to the front door through the connecting portion (for example, Patent Document 4).

特開２００９−２６９５９１号公報JP 2009-269591 A 特開２００８−５６１３８号公報JP 2008-56138 A 特開２００９−２９２０２号公報JP 2009-29202 A 特許第３７７６００３号公報Japanese Patent No. 3777003

従来の前部衝突対策は、局所的な衝突荷重の伝達に関するものであり、ホイールハウスアッパメンバに入力される前突荷重を、フロントピラー、フロントドアを経由させて車体後方へ伝達すると云う一連の衝突荷重伝達を考慮したものでないため、ホイールハウスアッパメンバより車体後部への前突荷重の伝達が十分でない。   Conventional frontal collision countermeasures are related to the transmission of local collision loads, and a series of frontal collision loads input to the wheel house upper member are transmitted to the rear of the vehicle body via the front pillars and front doors. Since the impact load transmission is not taken into consideration, the front impact load is not sufficiently transmitted from the wheel house upper member to the rear portion of the vehicle body.

例えば、フロントピラーの内面にドアヒンジスチフナが取り付けられたものは、フロントピラーからドアヒンジ部分を荷重伝達路としたフロントドアのドアビーム部材へ伝達が改善されても、フロントピラーへの前突荷重の入力について考慮がなく、前突荷重のフロントピラーへの伝達が十分でない。   For example, if a door hinge stiffener is attached to the inner surface of the front pillar, even if the transmission from the front pillar to the door beam member of the front door with the door hinge portion as the load transmission path is improved, the front impact load input to the front pillar There is no consideration, and the transmission of the front impact load to the front pillar is not sufficient.

アッパメンバがフロントピラーとの接続に加えてガセットプレートを用いてダシュボードアッパメンバの左右側部に接続されているものは、アッパメンバのフロントピラー側の接続強度が増すものの、ガセットプレートを用いたアッパメンバとダシュボードアッパメンバとの接続部は、車体前後方向で見てフロントドアのドアビーム部材の配置位置より車体幅方向の内側に偏倚した位置にあるので、アッパメンバからドアビーム部材への前突荷重の伝達経路が屈曲したものとなり、アッパメンバからドアビーム部材への前突荷重の伝達が十分でない。   When the upper member is connected to the left and right sides of the upper member of the dashboard board using a gusset plate in addition to the connection to the front pillar, the connection strength of the upper member on the front pillar side is increased, but the upper member and dashboard board using the gusset plate are increased. The connecting part with the upper member is located inwardly in the vehicle width direction from the position of the door beam member of the front door when viewed in the longitudinal direction of the vehicle body, so the transmission path of the front impact load from the upper member to the door beam member is bent. Therefore, the transmission of the front impact load from the upper member to the door beam member is not sufficient.

フロントフェンダエプロンメンバのフロントピラーとの接続側に形成されたビードとフロントピラーとによってボックス断面形状部が形成されたものは、フロントフェンダエプロンメンバとフロントピラーとの結合部の強度が増すものの、ボックス断面形状部がフロントフェンダエプロンメンバとドアビーム部材との間に車体前後方向に一直線上に連続していないため、フロントフェンダエプロンメンバからドアビーム部材へのボックス断面形状部による荷重伝達経路が中断し、フロントフェンダエプロンメンバからドアビーム部材への前突荷重の伝達が十分でない。   Although the box cross-sectional shape is formed by the bead and the front pillar formed on the connection side of the front fender apron member with the front pillar, the strength of the connecting portion between the front fender apron member and the front pillar is increased. Since the cross-sectional shape part is not continuous in a straight line in the vehicle longitudinal direction between the front fender apron member and the door beam member, the load transmission path by the box cross-sectional shape part from the front fender apron member to the door beam member is interrupted. The transmission of the front impact load from the fender apron member to the door beam member is not sufficient.

本発明が解決しようとする課題は、アッパメンバとフロントピラーとの間の前突荷重伝達と、フロントピラーとドアビーム部材との間の前突荷重伝達とを関連付けて改善し、アッパメンバに入力された前突荷重の車体後部への伝達が、より一層効率よく良好に行われるようにすることである。   The problem to be solved by the present invention is to improve the front collision load transmission between the upper member and the front pillar in association with the front collision load transmission between the front pillar and the door beam member. The transmission of the impulsive load to the rear part of the vehicle body is performed more efficiently and satisfactorily.

この車体側部構造によれば、アッパメンバ（２２）とフロントピラー（１０）とフロントドア（２０）の各々に補強部材が取り付けられ、アッパメンバ（２２）に取り付けられた第１の補強部材４０）と、フロントピラー（１０）に取り付けれた第２の補強部材（４６）と、フロントドア（２０）のインナパネル（２０Ｂ）に取り付けられた第３の補強部材４８の３者が、車体前後方向で見て、互いにオーバラップする部分を含んでいるから、このオーバラップ部分によって、アッパメンバ（２２）とフロントピラー（１０）との間の前突荷重伝達と、フロントピラー（１０）とドアビーム部材（４８）との間の前突荷重伝達とが、連続直線状の荷重伝達経路をもって行われるようになり、アッパメンバ（２２）に入力された前突荷重のフロントピラー（１０）、ドアビーム部材（４８）を経由しての車体後部への伝達が良好に行われるようになる。   According to this vehicle body side structure, a reinforcing member is attached to each of the upper member (22), the front pillar (10), and the front door (20), and the first reinforcing member 40 attached to the upper member (22). The three members, the second reinforcing member (46) attached to the front pillar (10) and the third reinforcing member 48 attached to the inner panel (20B) of the front door (20), are viewed in the longitudinal direction of the vehicle body. In this case, the overlapping part includes a front collision load transmission between the upper member (22) and the front pillar (10), and the front pillar (10) and the door beam member (48). Is transmitted through a continuous linear load transmission path, and the flow of the front impact load input to the upper member (22) is transmitted.

The upper member stiffener 40 extends from the connecting portion with the front pillar 10 to the front of the vehicle body, and is welded to the inner surface of the outer upper member 22B with upper and lower weld pieces 40A and 40B, and has a closed cross section with the outer upper member 22B. Forming. The upper member stiffener 40 includes a horizontal surface portion 40C extending substantially horizontally in the longitudinal direction of the vehicle body.

本実施例では、アッパメンバ２２は、フロントピラー１０との連結部の側に上方へ屈曲した屈曲部２２Ｃ（図２参照）を有している。アッパメンバ用スチフナ４０の上側の溶接片４０Ａは屈曲部２２Ｃに倣う形状をもって屈曲部２２Ｃの内面に溶接されている。   In the present embodiment, the upper member 22 has a bent portion 22 </ b> C (see FIG. 2) bent upward on the side of the connecting portion with the front pillar 10. The upper weld piece 40A of the upper member stiffener 40 is welded to the inner surface of the bent portion 22C with a shape that follows the bent portion 22C.

これにより、アッパメンバ２２が前方に大きく傾斜したデザインでも、前突荷重伝達に有用な水平面部４０Ｃをアッパメンバ用スチフナ４０に容易に形成でき、車体デザインの自由度が向上する。   Thereby, even if the upper member 22 is greatly inclined forward, the horizontal surface portion 40C useful for front impact load transmission can be easily formed in the upper member stiffener 40, and the degree of freedom in vehicle body design is improved.

なお、図示されていないが、ロアメンバ２４も、アッパメンバ２２と同様に、アウタロアメンバとインナロアメンバとの接合体により構成され、閉断面形状をなしている。   Although not shown, the lower member 24 is also composed of a joined body of an outer lower member and an inner lower member, and has a closed cross-sectional shape, like the upper member 22.

フロントピラー１０は、図５に示されているように、アウタピラーパネル１０Ａとインナピラーパネル１０Ｂとの接合体により構成され、閉断面形状をなしている。アウタピラーパネル１０Ａの外面には、図１〜図３に示されているように、フロントドア用の上部ドアヒンジ４２と下部ドアヒンジ４４とが取り付けられている。上部ドアヒンジ４２、下部ドアヒンジ４４は、フロントドア１０をアウタピラーパネル１０Ａに開閉可能に取り付けている。   As shown in FIG. 5, the front pillar 10 is configured by a joined body of an outer pillar panel 10 </ b> A and an inner pillar panel 10 </ b> B and has a closed cross-sectional shape. As shown in FIGS. 1 to 3, an upper door hinge 42 and a lower door hinge 44 for a front door are attached to the outer surface of the outer pillar panel 10 </ b> A. The upper door hinge 42 and the lower door hinge 44 attach the front door 10 to the outer pillar panel 10A so that it can be opened and closed.

フロントピラー１０内にはドアヒンジ補強部材（第２の補強部材）４６が取り付けられている。ドアヒンジ補強部材４６は上部ドアヒンジ４２と整合する位置に設けられ、上部ドアヒンジ４２のフロントピラー１０に対する取付部の補強を行う。   A door hinge reinforcing member (second reinforcing member) 46 is attached in the front pillar 10. The door hinge reinforcing member 46 is provided at a position aligned with the upper door hinge 42 and reinforces the attachment portion of the upper door hinge 42 with respect to the front pillar 10.

詳細には、ドアヒンジ補強部材４６は、ハット断面形状で、上下の溶接片４６Ａ、４６Ｂと、上下の水平片（水平面部）４６Ｄ、４６Ｅによって上下の溶接片４６Ａ、４６Ｂに接続された頂片４６Ｃとを折曲形成され、上下の溶接片４６Ａ、４６Ｂをインナピラーパネル１０Ｂの内面に溶接され、頂片４６Ｃをアウタピラーパネル１０Ａの内面に、溶接、あるいは上部ドアヒンジ４２をアウタピラーパネル１０Ａに固定するためのボルト等の締結具（図示省略）によって固定されている。   Specifically, the door hinge reinforcing member 46 has a hat cross-sectional shape, and has top and bottom weld pieces 46A and 46B and top pieces 46C connected to the upper and lower weld pieces 46A and 46B by upper and lower horizontal pieces (horizontal plane portions) 46D and 46E. The upper and lower weld pieces 46A, 46B are welded to the inner surface of the inner pillar panel 10B, the top piece 46C is welded to the inner surface of the outer pillar panel 10A, or the upper door hinge 42 is fixed to the outer pillar panel 10A. It is fixed by fasteners (not shown) such as bolts.

これにより、ドアヒンジ補強部材４６は、インナピラーパネル１０Ｂとで閉断面を形成し、しかも、上下の水平片４６Ｄ、４６Ｅによってフロントピラー１０の内部を上下に区切るバルクヘッド構造をなしている。   Thereby, the door hinge reinforcing member 46 forms a closed cross section with the inner pillar panel 10B, and has a bulkhead structure in which the interior of the front pillar 10 is vertically divided by the upper and lower horizontal pieces 46D and 46E.

フロントドア２０は、図６に示されているように、アウタドアパネル２０Ａとインナドアパネル２０Ｂとの接合体により構成されている。インナドアパネル２０Ｂには、図１、図２に示されているように、当該ドアパネルの上縁に沿って車体前後方向に延在するドアビーム部材（第３の補強部材）４８が取り付けられている。   As shown in FIG. 6, the front door 20 is constituted by a joined body of an outer door panel 20A and an inner door panel 20B. As shown in FIGS. 1 and 2, a door beam member (third reinforcing member) 48 that extends in the longitudinal direction of the vehicle body along the upper edge of the door panel is attached to the inner door panel 20B.

ドアビーム部材４８は、Ｓ字の横断面形状をしており、インナドアパネル２０Ｂの車体前後方向の幅一杯に略水平に延在し、上下の溶接片４８Ａ、４８Ｂをインナドアパネル２０Ｂの内面に溶接され、下側の溝形部４８Ｃとインナドアパネル２０Ｂとで閉断面を形成している。   The door beam member 48 has an S-shaped cross section, extends substantially horizontally to the full width of the inner door panel 20B in the longitudinal direction of the vehicle body, and upper and lower weld pieces 48A and 48B are welded to the inner surface of the inner door panel 20B. The lower groove portion 48C and the inner door panel 20B form a closed cross section.

なお、アウタドアパネル２０Ａの内面には、側部衝突対策用のドアビーム部材５０、５２が取り付けられている（図１、図２参照）。   In addition, door beam members 50 and 52 for side collision countermeasures are attached to the inner surface of the outer door panel 20A (see FIGS. 1 and 2).

本発明において、重要なことは、アッパメンバ用スチフナ４０とドアヒンジ補強部材４６とドアビーム部材４８とが、車体前後方向で見て、互いにオーバラップする部分を含んでおり、更には、この３者がオーバラップする部分は、略水平に一直線上に存在していることである。   In the present invention, what is important is that the upper member stiffener 40, the door hinge reinforcing member 46, and the door beam member 48 include portions that overlap each other when viewed in the longitudinal direction of the vehicle body. The wrapping portion is present on a straight line substantially horizontally.

このオーバラップ部分によって、アッパメンバ２２とフロントピラー１０との間の前突荷重の伝達と、フロントピラー１０とドアビーム部材４８との間の前突荷重の伝達とが、連続直線状の荷重伝達経路をもって行われるようになる。これにより、アッパメンバ２２に入力された前突荷重のフロントピラー１０、ドアビーム部材４８を経由しての車体後部への伝達が良好に行われるようになる。   By this overlap portion, the transmission of the front collision load between the upper member 22 and the front pillar 10 and the transmission of the front collision load between the front pillar 10 and the door beam member 48 have a continuous linear load transmission path. To be done. As a result, the front collision load input to the upper member 22 is transmitted to the rear portion of the vehicle body through the front pillar 10 and the door beam member 48.

特に、このオーバラップする部分が、略水平に一直線上に存在していることにより、アッパメンバ２２に入力された前突荷重のフロントピラー１０、ドアビーム部材４８を経由しての車体後部への伝達が、曲げモーメントを生じることなく、効率よく良好に行われるようになる。   In particular, since the overlapping portions are present on a straight line substantially horizontally, the front collision load input to the upper member 22 is transmitted to the rear portion of the vehicle body via the front pillar 10 and the door beam member 48. Thus, it is performed efficiently and satisfactorily without causing a bending moment.

本実施例では、前突荷重伝達に有用なアッパメンバ用スチフナ４０の水平面部４０Ｃとドアヒンジ補強部材４６の上側の水平片４６Ｄの高さが一致し、さらに、これらとドアビーム部材４８のＳ字横断面の図心Ｇの高さが一致している。   In the present embodiment, the horizontal plane portion 40C of the upper member stiffener 40 useful for the front impact load transmission and the height of the horizontal piece 46D on the upper side of the door hinge reinforcing member 46 coincide with each other. The heights of the centroids G are equal.

これにより、アッパメンバ２２よりフロントピラー１０を経てドアビーム部材４８に至る連続直線状の水平に荷重伝達経路が形成されるから、アッパメンバ２２に入力された前突荷重のフロントピラー１０、ドアビーム部材４８を経由しての車体後部への伝達が、より一層、効率よく良好に行われるようになる。   As a result, a continuous straight horizontal load transmission path is formed from the upper member 22 through the front pillar 10 to the door beam member 48, so that the front impact load input to the upper member 22 passes through the front pillar 10 and the door beam member 48. Thus, transmission to the rear part of the vehicle body is performed more efficiently and satisfactorily.

また、アッパメンバ用スチフナ４０の水平面部４０Ｃは、両側に車体前後方向に延在する折曲稜線ａ、ｂを、ドアヒンジ補強部材４６の水平片４６Ｄも、両側に車体前後方向に延在する折曲稜線ｃ、ｄを有するので、これら水平面部４０Ｃ、水平片４６Ｄの車体前後方向の耐圧強度は相当高い。   Further, the horizontal surface portion 40C of the upper member stiffener 40 has bent ridge lines a and b extending in the vehicle longitudinal direction on both sides, and the horizontal piece 46D of the door hinge reinforcing member 46 is also bent in the vehicle longitudinal direction on both sides. Since the ridgelines c and d are included, the pressure resistance strength of the horizontal plane portion 40C and the horizontal piece 46D in the vehicle longitudinal direction is considerably high.

これにより、アッパメンバ用スチフナ４０の水平面部４０Ｃとドアヒンジ補強部材４６の上側の水平片４６Ｄによる車体後部への前突荷重伝達が、高い耐圧強度の状態で、効率よく良好に行われるようになる。   Thereby, the front impact load transmission to the rear portion of the vehicle body by the horizontal surface portion 40C of the upper member stiffener 40 and the horizontal piece 46D on the upper side of the door hinge reinforcing member 46 is efficiently and satisfactorily performed in a state of high pressure strength.

また、ドアビーム部材４８がＳ字横断面形状のものであることにより、フロントドア２０の車幅方向の幅が広くても、ドアビーム部材４８のＳ字横断面の図心Ｇを、車体前後方向で見て、車幅方向で、フロントピラー１０との荷重伝達経路と一致させることができ、ドアビーム部材４８への前突荷重の伝達が良好に行われることを確保できる。   Further, since the door beam member 48 has an S-shaped cross section, the centroid G of the S-shaped cross section of the door beam member 48 can be set in the longitudinal direction of the vehicle body even when the front door 20 is wide in the vehicle width direction. As seen, it can be made to coincide with the load transmission path with the front pillar 10 in the vehicle width direction, and it can be ensured that the front impact load to the door beam member 48 is transmitted well.

上述の前突荷重伝達において、アッパメンバ用スチフナ４０、ドアヒンジ補強部材４６は、閉断面のアッパメンバ２２、フロントピラー１０、インナドアパネル２０Ｂの各々において内部に更に閉断面を形成するから、フロントピラー１０、インナドアパネル２０Ｂの車体前後方向の耐圧荷重（剛性）が著しく向上し、これらが前突荷重によって変形することなく、ドアビーム部材４８への前突荷重の伝達が良好に行われる。   In the above-described front collision load transmission, the upper member stiffener 40 and the door hinge reinforcing member 46 further form a closed cross section inside each of the closed cross section upper member 22, the front pillar 10, and the inner door panel 20B. The pressure resistance load (rigidity) in the longitudinal direction of the vehicle body of the door panel 20B is remarkably improved, and the front impact load is transmitted to the door beam member 48 without deformation due to the front impact load.

特に、ドアヒンジ補強部材４６は、フロントピラー１０の内部を上下に区切るバルクヘッド構造をなしているから、フロントピラー１０の強度、剛性を大幅に向上させる。   In particular, since the door hinge reinforcing member 46 has a bulkhead structure that divides the interior of the front pillar 10 into upper and lower portions, the strength and rigidity of the front pillar 10 are greatly improved.
