Description

本発明は、ドアパネルの中空断面の内部にドアビーム部材が前後方向に渡設されたドアビームブラケット構造に関する。   The present invention relates to a door beam bracket structure in which a door beam member is provided in a front-rear direction inside a hollow section of a door panel.

自動車等の車両において、従来から前面衝突や後面衝突に対する効果的な衝撃吸収手段が数多く提案されて採用されている。そして、近年では側面衝突に対しても様々な安全技術が開発されてきている。特に、側面衝突時において、車両の側面に位置するドアが車室内に侵入することによる搭乗者への危険度すなわち傷害値をいかに低減させるかが考慮されるべき重要な課題となっている。そのためには、ドア自体の衝撃吸収が効果的に行われることはもとより、ドア自体では衝撃を吸収しきれない大きな側面荷重が加わった場合にも、妄りにドアが車室内に侵入してこない効果的な抑止手段を配設する必要があった。そのようなドアの変形侵入から乗員を保護する技術として、内部にドアビーム部材が前後方向に渡設されたドアが提案されている（例えば下記特許文献１参照）。
特開２００３−２５８４２号公報（請求項１参照）。 In vehicles such as automobiles, many effective shock absorbing means for frontal collision and rearward collision have been proposed and adopted. In recent years, various safety technologies have been developed against side collisions. In particular, it is an important issue to consider how to reduce the risk to passengers, that is, the injury value, due to the door located on the side of the vehicle entering the vehicle interior during a side collision. For that purpose, the impact of the door itself is effectively absorbed, and even when a large side load is applied that the door itself cannot absorb the impact, the door does not intrude into the passenger compartment. It was necessary to arrange a deterrent means. As a technique for protecting an occupant from such door deformation and penetration, a door in which a door beam member is provided in the front-rear direction has been proposed (for example, see Patent Document 1 below).
JP 2003-25842 A (refer to claim 1).

図４を用いて前記特許文献１に開示された自動車のドア構造について説明する。フロントドア１１０のフロント側インパクトビーム（ドアビーム）１３３の上方に、前後方向に略水平に延びる張り剛性リンホース１３５を配設するとともに、リヤドア１１１のリヤ側インパクトビーム１３８を前記張り剛性リンホース１３５と略同じ高さ位置にて前後方向に連続するように配設し、前記フロント側インパクトビーム１３３の前端部１３３ａおよび張り剛性リンホース１３５の前端部１３５ａをヒンジ部材１１２ａ（図４（Ｂ））の近傍に位置させて配置し、前記フロント側インパクトビーム１３３の後端部１３３ｂをセンタピラー１０８の下端部のロッカパネル１０７の近傍に配置したものである。このような構成により、ドア重量および部品点数を増加させたり、側面衝突に対するインパクトビームの機能を損なうことなく、前面衝突時の入力を車体後部に効率よく伝達できる自動車用ドアが提供された。   The automobile door structure disclosed in Patent Document 1 will be described with reference to FIG. A tension rigid phosphorus hose 135 extending substantially horizontally in the front-rear direction is disposed above the front side impact beam (door beam) 133 of the front door 110, and the rear impact beam 138 of the rear door 111 is substantially the same as the tension rigid phosphorus hose 135. The front end portion 133a of the front impact beam 133 and the front end portion 135a of the tension rigid phosphorus hose 135 are positioned in the vicinity of the hinge member 112a (FIG. 4B). The rear end portion 133b of the front side impact beam 133 is disposed in the vicinity of the rocker panel 107 at the lower end portion of the center pillar 108. With such a configuration, an automobile door that can efficiently transmit the input at the time of a frontal collision to the rear part of the vehicle body without increasing the door weight and the number of parts or impairing the function of the impact beam with respect to a side collision has been provided.

しかしながら、前記特許文献１に開示されたものでは、側面衝突や斜め前方からの衝突に遭遇して大きな衝撃荷重を受けたような場合に、インパクトビーム端部のドアパネルに対する接合部、例えばスポット溶接部等が剥離して抜け落ちる虞れがあった。一般に、ドアビーム端部をドアパネルに接合するには、通常、前記図４の従来例のもののように、ドアビーム端部の平板部を直接ドアパネルにスポット溶接等により接合するか、図５に示すように、ブラケット部材２０３を介してドアビーム端部をドアパネルに接合していた。ブラケット部材２０３は、ドアビーム端部を受け入れるビーム端部受入部２０４を形成した本体部２０３Ａ（ブラケットＡ）と、ドアパネルへの接合部を構成する取付ブラケット２０３Ｂ（ブラケットＢ）とから構成された。   However, in the one disclosed in Patent Document 1, when a large impact load is encountered due to a side collision or a collision from obliquely forward, a joint portion of the impact beam end to the door panel, for example, a spot welded portion. There is a risk that the material will peel off. Generally, in order to join the door beam end portion to the door panel, the flat plate portion of the door beam end portion is usually joined directly to the door panel by spot welding or the like, as shown in FIG. The end of the door beam is joined to the door panel via the bracket member 203. The bracket member 203 is composed of a main body portion 203A (bracket A) that forms a beam end receiving portion 204 that receives a door beam end portion, and an attachment bracket 203B (bracket B) that forms a joint to the door panel.

前者の図４の例では、インパクトビーム（ドアビーム）の端部が単純な構造で済むが、接合部の殆どが剪断方向の衝撃荷重を受けて剥離し易く、また、後者の図５の例では、ブラケットＡとブラケットＢとの合い面精度の確保が困難であり、ドアパネルとのスポット溶接等の接合部の部位もブラケットＢに限定されて、より高い強度でのドアビーム端部のブラケット構造の構築は困難であった。   In the former example of FIG. 4, the end of the impact beam (door beam) can be a simple structure, but most of the joints are easily peeled by receiving an impact load in the shear direction, and in the latter example of FIG. 5. It is difficult to ensure the accuracy of the mating surface between the bracket A and the bracket B, and the part of the joint part such as spot welding with the door panel is also limited to the bracket B, so that the construction of the bracket structure of the door beam end with higher strength is constructed. Was difficult.

そこで本発明では、前記課題を解決して、製造が容易で他の構造物との協働による高い補剛効果が期待でき、接合部の剥離も有効に抑制されてドアビームの機能を充分に発揮し、ドアの車室内への侵入を有効に防止し得るドアビームブラケット構造を提供する。   Therefore, the present invention solves the above problems, can be easily manufactured, and can be expected to have a high stiffening effect by cooperating with other structures, and can effectively exhibit the function of the door beam by effectively suppressing separation of the joint. And a door beam bracket structure capable of effectively preventing the door from entering the vehicle interior.

A door beam bracket having a door panel inner member provided with a bent portion, a door beam member provided in the front-rear direction inside the hollow cross section, and a bracket member for supporting an end of the door beam member on the door panel inner member. In the structure, the bracket member is connected to and joined to the upper step portion and the lower step portion of the door panel inner member, and the bracket member includes a flat plate portion and a door panel inner member that are joined to the upper step portion of the door panel inner member. and a bridge portion which is joined to the lower portion, constitutes a box shape in cooperation with the door panel inner member The door panel inner member has a phosphorus hose hinge member that is joined to the upper and lower steps of the door panel inner member and defines a frame shape along the vertical direction in cooperation with the door panel inner member, and the bracket member is the phosphorus hose hinge member characterized in that which is joined to the door panel inner member at the junction of the door panel inner member, it is an unit for the Re this problem solution.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an enlarged view of a main part of a door, showing a cross section (FIGS. 1A to 1C) showing a support portion of a door beam end portion on which one embodiment of the door beam bracket structure of the present invention is applied, FIG. FIG. 4 is an enlarged perspective view showing only a bracket member. FIG. 3 is a side view of the vehicle body including a door portion to which the door beam bracket structure of the present invention is applied. As shown in FIG. 1, the basic structure of the door beam bracket structure according to the present invention includes a door panel outer member, an upper step portion 5A formed on the outer side of the vehicle body, and an upper step portion 5A formed integrally with the door panel outer member. A door panel inner member 5 having a bent portion formed of a lower step portion 5B formed inside the door and inside the vehicle body from the portion 5A, and door beam members 1 and 2 provided in the front-rear direction inside the hollow section, In a door beam bracket structure having a bracket member 3 that supports the end portions of the door beam members 1 and 2 to the door panel inner member 5, the bracket member 3 is passed to the upper step portion 5A and the lower step portion 5B of the door panel inner member 5. The bracket member 3 is connected to the upper step portion 5A of the door panel inner member 5 and the door panel inner. And a bridge portion 9 joined to the lower portion 5B of the timber 5, the door panel inner member 5 and cooperating with constitute a box-shaped, joined to the upper portion 5A and the lower part 5B of the door panel inner member 5 In addition, it has a phosphorus hose hinge member 6 that defines a frame shape along the vertical direction in cooperation with the door panel inner member 5, and the bracket member 3 is a joint between the phosphorus hose hinge member 6 and the door panel inner member 5. It is characterized by being joined to the door panel inner member 5 at a part SP .

図１に示すものは、リヤドアに施された本発明のドアビームブラケット構造の１つの実施例で、ドアビーム端部の支持部を断面とともに示すドアの要部拡大図である。図の例は、図３のＡ部にて示すように、フロントドアの後部の閉扉時にこれを受け入れる（車体側）ピラーレスのスライドドアや観音開きリヤドアの前部に施されたドアビームブラケット構造の例であるが、ピラーレスのドアに限ることなく、ピラーを有する形式のドアにも適用が可能であることは言うまでもない。ピラーレスの場合、フロントドアの後部がリヤドアであるピラーレススライドドア前部に対して閉じられ際に、本来、ドアラッチ部材やキャッチャ部材を有効に機能させ得る、車体側のピラーが存在しない。それ故に、リンホースヒンジ部材６（図１（Ｃ））に添設して接合されたドアパネルインナ部材５が車体側のピラーによるバックアップが期待できない。   FIG. 1 is an enlarged view of a main part of a door showing a support portion of a door beam end portion together with a cross section in one embodiment of the door beam bracket structure of the present invention applied to a rear door. The example shown in the figure is an example of a door beam bracket structure applied to the front part of a pillarless slide door or a double door rear door that accepts the front door when the rear part of the front door is closed (vehicle side), as shown in part A of FIG. Needless to say, the present invention can be applied not only to a pillarless door but also to a door having a pillar. In the case of pillarless, there is essentially no pillar on the vehicle body side that can effectively function the door latch member and the catcher member when the rear portion of the front door is closed with respect to the front portion of the pillarless slide door that is the rear door. Therefore, the door panel inner member 5 attached and joined to the phosphorus hose hinge member 6 (FIG. 1C) cannot be expected to be backed up by the pillar on the vehicle body side.

そのようなことから、ドアビームを支持するブラケット部材近傍の強度が充分に確保される必要がある。図１（Ｃ）に示すように、ドアのフレーム形状を画定するリンホースヒンジ部材６に添設して接合されたドアパネルインナ部材５の段差部５Ａ、５Ｂ間に接合されるブラケット部材３は、図２に示すような構成が採用される。上下に配設された第１および第２ドアビーム部材１、２をそれぞれ受け入れるビーム端部受入部４Ａ、４Ｂが形成された平板状部８と、その前端部近傍の両側から下方（図の紙背側）へ延設されるブリッジ部９の脚部９Ａ、９Ｂとが一体構造にて構成される。前記平板状部８の前縁部１０、および脚部９Ａ、９Ｂの下端部にはドアパネルインナ部材５の接合面と平行に延びる第１および第２接合面１１Ａ、１１Ｂが形成される。   For this reason, it is necessary to sufficiently ensure the strength in the vicinity of the bracket member that supports the door beam. As shown in FIG. 1 (C), the bracket member 3 joined between the stepped portions 5A and 5B of the door panel inner member 5 joined and joined to the phosphorus hose hinge member 6 defining the frame shape of the door, A configuration as shown in FIG. 2 is employed. A flat plate-like portion 8 formed with beam end receiving portions 4A and 4B for receiving first and second door beam members 1 and 2 disposed above and below, and downward from both sides in the vicinity of the front end portion (the back side of the figure) ) And the leg portions 9A and 9B of the bridge portion 9 extending in a single structure. First and second joint surfaces 11A and 11B extending in parallel with the joint surface of the door panel inner member 5 are formed at the front edge portion 10 of the flat plate portion 8 and the lower end portions of the leg portions 9A and 9B.

前記平板状部８の前縁部１０には例えば４つのスポット溶接等による接合部ＳＰが形成される。また、前記脚部９Ａ、９Ｂの下端部の接合面１１Ａ、１１Ｂにもそれぞれスポット溶接等による接合部ＳＰが形成される。これらの平板状部８の前縁部１０の接合部ＳＰと脚部９Ａ、９Ｂの下端部の接合面１１Ａ、１１Ｂの接合部ＳＰとは、車体側面視で所定距離Ｌ（図１（Ａ）参照）を置いている。ブラケット部材３の平板状部８および脚部９には適宜の補強用のリブが適宜形成される。   For example, four joints SP are formed on the front edge portion 10 of the flat plate portion 8 by spot welding or the like. Also, joints SP by spot welding or the like are formed on the joint surfaces 11A and 11B at the lower ends of the legs 9A and 9B, respectively. The joining portion SP of the front edge portion 10 of the flat plate-like portion 8 and the joining surfaces 11A and 11B of the lower end portions of the leg portions 9A and 9B are separated by a predetermined distance L (FIG. 1A). See). Appropriate reinforcing ribs are appropriately formed on the flat plate portion 8 and the leg portion 9 of the bracket member 3.

このような構成のブラケット部材３を介してドアビーム部材１、２をドアパネルインナ部材５に取り付けた状態を示すものが図１（Ｂ）である。図１（Ｃ）に示すように、リヤドアの前端部のフレーム形状を画定するリンホースヒンジ部材６に添設されたドアパネルインナ部材５の段差部５Ａ、５Ｂに、ブラケット部材３が接合されて配設される。図１（Ｂ）は、図示省略のドアパネルアウタを取り外した状態を示しており、ドアパネルインナ部材５の曲折部により形成される上段部５Ａ（車体外側）と下段部５Ｂ（車体内側）に渡設されてブラケット部材３が接合される。したがって、上段部５Ａには平板状部８の前縁部１０が接合され、下段部５Ｂにはブリッジ部９の各脚部９Ａ、９Ｂの下端部の接合面１１Ａ、１１Ｂがそれぞれスポット溶接ＳＰ等により接合される。   FIG. 1B shows a state in which the door beam members 1 and 2 are attached to the door panel inner member 5 through the bracket member 3 having such a configuration. As shown in FIG. 1C, the bracket member 3 is joined to the step portions 5A and 5B of the door panel inner member 5 attached to the phosphorus hose hinge member 6 that defines the frame shape of the front end portion of the rear door. Established. FIG. 1 (B) shows a state in which a door panel outer (not shown) is removed, and is installed on the upper step portion 5A (vehicle body outer side) and the lower step portion 5B (vehicle body inner side) formed by the bent portion of the door panel inner member 5. Then, the bracket member 3 is joined. Therefore, the front edge portion 10 of the flat plate-like portion 8 is joined to the upper step portion 5A, and the joining surfaces 11A and 11B of the lower end portions of the leg portions 9A and 9B of the bridge portion 9 are spot welded SP and the like to the lower step portion 5B. Are joined together.

前記ブラケット部材３を車体後方から見た断面図が図１（Ａ）であり、平板状部８の両側から下方へ延びる第１脚部９Ａおよび第２脚部９Ｂの下端部の接合面１１Ａ、１１Ｂにより、ドアパネルインナ部材５の下段部５Ｂに接合された状態が明瞭に分かる。ドアパネルインナ部材５における上段部５Ａと下段部５Ｂとから形成される段部の差は、ブラケット部材３における脚部９Ａ、９Ｂの長さに影響を与える。したがって、ブラケット部材３のドアパネルインナ部材５における上段部５Ａと下段部５Ｂへの接合と、ブラケット部材３自体のブリッジ形状によってドアビーム部材１、２の端部の支持部近傍がボックス形状にて効果的に補剛されて補強機能が強化される。   A cross-sectional view of the bracket member 3 as viewed from the rear of the vehicle body is FIG. 1A, and the joint surfaces 11A of the lower ends of the first leg portion 9A and the second leg portion 9B extending downward from both sides of the flat plate-like portion 8; By 11B, the state joined to the lower step part 5B of the door panel inner member 5 can be clearly seen. The difference in the step portion formed by the upper step portion 5A and the lower step portion 5B in the door panel inner member 5 affects the length of the leg portions 9A and 9B in the bracket member 3. Therefore, the box member shape is effective in the vicinity of the support portion at the end of the door beam members 1 and 2 due to the joining of the bracket member 3 to the upper step portion 5A and the lower step portion 5B in the door panel inner member 5 and the bridge shape of the bracket member 3 itself. The reinforcement function is strengthened.

ブラケット部材３の平板状部８のドアパネルインナ部材５の上段部５Ａへの接合と、ブラケット部材３の脚部９Ａ、９Ｂのドアパネルインナ部材５の下段部５Ｂへの接合により、平板状部８の接合部に加えてブリッジ部９における脚部９Ａ、９Ｂの接合部を増やすことができて衝撃荷重が分散されるので剥離が抑制され、しかも、平板状部８の前縁部１０の接合部ＳＰと脚部９Ａ、９Ｂの接合面１１Ａ、１１Ｂの接合部ＳＰとが所定距離Ｌを置いていることにより、脚部９Ａ、９Ｂに作用する圧縮衝撃荷重に対して比較的広い範囲で耐性を示すことができるので、斜め前方からの衝撃荷重や側面からの衝撃荷重が加わっても、前記平板状部８の前縁部１０の接合部ＳＰに加わる剪断方向の衝撃荷重を、脚部９Ａ、９Ｂの接合面１１Ａ、１１Ｂの接合部ＳＰに対して圧縮方向の衝撃荷重として分散転嫁することができて、ブラケット部材３における全体の接合部の剪断剥離を効果的に低減させることが可能となり、ドアビーム部材の機能を充分に発揮して乗員を保護するとともに、ドアの車室内への侵入が防止される。   By joining the flat plate portion 8 of the bracket member 3 to the upper step portion 5A of the door panel inner member 5 and joining the leg portions 9A and 9B of the bracket member 3 to the lower step portion 5B of the door panel inner member 5, In addition to the joint portions, the joint portions of the leg portions 9A and 9B in the bridge portion 9 can be increased and the impact load is dispersed, so that peeling is suppressed, and the joint portion SP of the front edge portion 10 of the flat plate-like portion 8 is suppressed. And the joint surfaces SP of the leg portions 9A and 9B have a predetermined distance L, thereby exhibiting resistance in a relatively wide range against the compressive impact load acting on the leg portions 9A and 9B. Therefore, even if an impact load from obliquely forward or an impact load from the side is applied, the impact load in the shearing direction applied to the joint SP of the front edge portion 10 of the flat plate portion 8 is reduced to the leg portions 9A and 9B. Bonding surfaces 11A and 11B The joint SP can be distributed and passed as an impact load in the compression direction, and the shear peeling of the entire joint in the bracket member 3 can be effectively reduced, and the door beam member functions sufficiently. This protects the occupant and prevents the door from entering the passenger compartment.

また、図２に示すように、前記ブラケット部材３は、ドアパネルインナ部材５の段差部の一方（上段部）５Ａに接合される平板状部８と、ドアパネルインナ部材５の段差部の他方（下段部）５Ｂに接合されるブリッジ部９とを一体構造にて構成した。これにより、前記ブリッジ部９がドアビーム部材１、２の端部に加わる圧縮衝撃荷重に対してよく耐性を示して、ブラケット部材３に加わる剪断方向の衝撃荷重の負担を軽減して剥離を有効に抑制するとともに、ブラケット部材３を一体構造とすることにより、従来の２つの構成要素から構成されたもののように、合い面精度等に煩わされることなく製造が容易となる。   As shown in FIG. 2, the bracket member 3 includes a flat plate portion 8 joined to one of the step portions (upper step portion) 5 </ b> A of the door panel inner member 5 and the other step portion (lower step) of the door panel inner member 5. Part) The bridge part 9 to be joined to 5B is formed as an integral structure. Accordingly, the bridge portion 9 is well resistant to the compressive impact load applied to the ends of the door beam members 1 and 2, and the burden of the impact load in the shearing direction applied to the bracket member 3 is reduced, thereby effectively peeling. In addition to being suppressed, the bracket member 3 has an integral structure, which makes it easy to manufacture without bothering the mating surface accuracy and the like as in the case of the conventional two-component structure.

また、図１（Ｃ）に示すように、前記ブリッジ部９におけるドアパネルインナ部材５への接合部ＳＰがドアのリンホースヒンジ部材６の接合部を兼用するように構成する。これにより、比較的大きな強度を必要とするドアのリンホースヒンジ部材６が、ドアパネルインナ部材５の段差部にブリッジ形態にてブラケット部材３が渡設・接合されて構成されたボックス状構造物により効果的に補強されるとともに、ドアビーム部材１、２の端部を支持するブラケット部材３自体が、互いに他の構造物であるドアのリンホースヒンジ部材６との協働により、補剛効果の高いドアビーム端部のブラケット構造が構築されて、接合部の剥離を抑制でき、ドアビーム部材の機能を充分に発揮して乗員を保護するとともに、ドアの車室内への侵入が防止される。   Further, as shown in FIG. 1C, the connecting portion SP to the door panel inner member 5 in the bridge portion 9 is also used as the connecting portion of the phosphorus hose hinge member 6 of the door. As a result, the phosphorus hose hinge member 6 of the door that requires relatively high strength is formed by a box-like structure in which the bracket member 3 is bridged and joined to the stepped portion of the door panel inner member 5 in a bridge form. The bracket member 3 itself which is effectively reinforced and supports the end portions of the door beam members 1 and 2 has a high stiffening effect by cooperating with the phosphorus hose hinge member 6 of the door which is another structure. The bracket structure at the end of the door beam is constructed, and the separation of the joint can be suppressed, the function of the door beam member is fully exhibited to protect the passenger, and the door is prevented from entering the vehicle interior.

以上、本発明の各実施の形態について説明してきたが、本発明の趣旨の範囲内で、ドアビーム部材の形状（丸パイプ状、角パイプ状、Ｈ形断面等）、形式、数、ブラケット部材の形状（補強リブの形成形態を含む平板部およびブリッジ部のそれぞれの形状、平板部における接合部とブリッジ部における接合部との距離、また、必要に応じてブリッジ部における脚部間に圧縮荷重用の補助脚部材を付設することもできる）、形式、およびそのドアパネルインナ部材の段差部への渡設・接合形態（スポット溶接、ボルト締結等およびその数、平板部における接合部からブリッジ部における接合面にかけての縁部をドアパネルインナ部材の段差部の断面形状に適合させて添設させるように構成してもよい）、ブラケット部材に対するドアビーム部材端部の支持形態（ビーム端部受入部を絞り加工によって一体形成してもよいし、別体にてビーム端部受入部材を接合した抱持形態の他、ドアビーム部材のブラケット部材への接合角度に応じてドアビーム部材の端部をカットして全周で接合してもよい）、ドアパネルインナ部材とリンホースヒンジ部材との接合形態（スポット溶接等の他、ボルト等による締結もなし得る）、取り付けられるべきドアパネルインナ部材およびリンホースヒンジ部材の段差形状等については適宜選定できる。   Each embodiment of the present invention has been described above.
