Description

本発明は、車体角部構造に関するものである。 The present invention relates to a vehicle body corner structure.

一般に、ハッチバックタイプ等の車両では、車両ボディが箱状に形成され、３面が交差した角部を有することがある。例えば、車体の後端且つ上部において、車幅方向に延びるクロスメンバと、サイドボディの上端部（進行方向に延びる部分）と、サイドボディ後端に設けられるエクステンション（上下方向に延びる部分）と、の３部材がそれぞれ有する板状の部分によって角部が形成される。さらに、サイドボディの上端部およびクロスメンバを上方から覆うようにルーフパネルが設けられる。 Generally, in a vehicle such as a hatchback type, the vehicle body may be formed in a box shape and may have corners where three surfaces intersect. For example, at the rear end and upper part of the vehicle body, a cross member extending in the vehicle width direction, an upper end portion of the side body (a portion extending in the traveling direction), and an extension provided at the rear end of the side body (a portion extending in the vertical direction). A corner portion is formed by a plate-shaped portion of each of the three members. Further, a roof panel is provided so as to cover the upper end portion of the side body and the cross member from above.

従来、このような角部において各部材を溶接によって接合する車体構造が提案されている（例えば特許文献１参照）。特許文献１に記載された車体構造では、車幅方向に延びるリヤルーフレールと、上下方向に延びるリヤピラーアウタと、が接合されるとともに、ルーフパネルと各部材とが、エクステンションを介して接続されている。 Conventionally, a vehicle body structure in which each member is joined by welding at such a corner portion has been proposed (see, for example, Patent Document 1). In the vehicle body structure described in Patent Document 1, the rear roof rail extending in the vehicle width direction and the rear pillar outer extending in the vertical direction are joined, and the roof panel and each member are connected via an extension. ..

特開２０１６−８８４４７号公報Japanese Unexamined Patent Publication No. 2016-88447

特許文献１に記載された車体構造では、適宜な位置で各部材を溶接することにより角部の強度の向上を図っている。しかしながら、車体構造における角部は、走行時の振動等による外力によって変形が生じやすい部位であり、溶接位置を工夫するだけでは変形を充分に抑制することは困難であった。このように角部が変形することにより、各部材間に設けられたシール材の割れや剥がれが生じてしまう可能性がある。また、車両ボディには、後端且つ上部以外にも角部が形成されることがあり、後端且つ上部と同様に変形を抑制することが望まれていた。 In the vehicle body structure described in Patent Document 1, the strength of the corner portion is improved by welding each member at an appropriate position. However, the corner portion in the vehicle body structure is a portion that is easily deformed by an external force due to vibration during traveling, and it is difficult to sufficiently suppress the deformation only by devising the welding position. Due to the deformation of the corners in this way, there is a possibility that the sealing material provided between the members may be cracked or peeled off. Further, the vehicle body may have corners formed in addition to the rear end and the upper portion, and it has been desired to suppress deformation as in the rear end and the upper portion.

本発明の目的は、変形を抑制することができる車体角部構造を提供することにある。 An object of the present invention is to provide a vehicle body corner structure capable of suppressing deformation.

The first plate portion and the second plate portion form an L-shaped corner portion that is convex to the outside of the vehicle by bending one end portion along the other, and the third plate portion is the end thereof. A first overlapping portion that is overlapped on the outside of the vehicle of the first plate portion, a second overlapping portion that is overlapped on the outside of the vehicle of the second plate portion, and the first overlapping portion and the second overlapping portion. It has a notch formed between them, and the L-shaped corner portion passes through the notch from the inside of the vehicle to the outside of the vehicle, and of the first plate portion and the second plate portion. A portion of the notch located on the outer side of the vehicle abuts on the bottom of the notch, the first overlapping portion is joined to at least the first plate portion, and the second overlapping portion is at least the second. It is characterized by being joined to a plate portion.

請求項１に記載された発明は、第１板部と第２板部と第３板部とが接合されることで３面が交差した角部が形成される車体角部構造であって、第１板部および第２板部は、一方の端部が他方に沿うように屈曲されることで車外側に凸のＬ字状角部を構成し、第３板部は、その端部に、第１板部の車外側に重ねられる第１重なり部と、第２板部の車外側に重ねられる第２重なり部と、第１重なり部と第２重なり部との間に形成された切欠き部と、を有し、Ｌ字状角部が車内側から車外側に向かって切欠き部を通過するとともに、第１板部および第２板部のうち切欠き部の車外側に位置する部分が、切欠き部の底部に当接し、第１重なり部が少なくとも第１板部に接合され、第２重なり部が少なくとも第２板部に接合されることを特徴とする。 The invention according to claim 1 is a vehicle body corner structure in which a corner portion where three surfaces intersect is formed by joining the first plate portion, the second plate portion, and the third plate portion. The first plate portion and the second plate portion form an L-shaped corner portion that is convex to the outside of the vehicle by bending one end portion along the other, and the third plate portion is formed at the end portion. , The cut formed between the first overlapping portion overlapped on the outside of the vehicle of the first plate portion, the second overlapping portion overlapped on the outside of the vehicle of the second plate portion, and the first overlapping portion and the second overlapping portion. It has a notch, and the L-shaped corner passes through the notch from the inside of the vehicle toward the outside of the vehicle, and is located on the outside of the notch of the first plate and the second plate. The portion abuts on the bottom of the notch, the first overlapping portion is joined to at least the first plate portion, and the second overlapping portion is joined to at least the second plate portion.

このような本発明によれば、第１板部および第２板部によって構成されるＬ字状角部が、車内側から車外側に向かって第３板部の切欠き部を通過することで、Ｌ字状角部が第１重なり部と第２重なり部とによって挟み込まれる。ここで、第１重なり部が少なくとも第１板部に接合され、第２重なり部が少なくとも第２板部に接合されることにより、Ｌ字状角部の移動（特にＬ字状角部が挟み込まれる方向の移動）が抑制される。また、Ｌ字状角部が切欠き部の底部に当接することで、Ｌ字状角部が第３板部に近づくことが規制される。このようにＬ字状角部の移動が抑制されることで、３面が交差した角部の変形を抑制することができる。 According to the present invention, the L-shaped corner portion composed of the first plate portion and the second plate portion passes through the notch portion of the third plate portion from the inside of the vehicle to the outside of the vehicle. , The L-shaped corner portion is sandwiched between the first overlapping portion and the second overlapping portion. Here, by joining the first overlapping portion to at least the first plate portion and joining the second overlapping portion to at least the second plate portion, the movement of the L-shaped corner portion (particularly, the L-shaped corner portion is sandwiched). Movement in the direction of movement) is suppressed. Further, the L-shaped corner portion comes into contact with the bottom portion of the notch portion, so that the L-shaped corner portion is restricted from approaching the third plate portion. By suppressing the movement of the L-shaped corner portion in this way, it is possible to suppress the deformation of the corner portion where the three surfaces intersect.

サイドボディアウタパネル３の車内側には、図４、５に示すように、クォータウィンドエクステンション７が設けられることで補強されている。クォータウィンドエクステンション７は、Ｘ方向を長手方向とするとともにＺＸ平面に沿って延びている。 As shown in FIGS. 4 and 5, the inside of the side body outer panel 3 is reinforced by providing a quarter wind extension 7. The quarter wind extension 7 has the X direction as the longitudinal direction and extends along the ZX plane.

ルーフバックインナエクステンション４は、ルーフパネル５の後端部且つ下方に配置されてＹ方向に沿って延びるクロスメンバの端部を構成する部材であって、ＸＹ平面に沿って延びることで第３板部として機能する。ルーフバックインナエクステンション４は、Ｙ方向外側端部において、ＹＺ平面に沿って延びる第１重なり部４１と、ＸＹ平面に沿って延びる第２重なり部と、が突出しており、第１重なり部４１と第２重なり部４２との間には切欠き部４３が形成されている。 The roof back inner extension 4 is a member that is arranged at the rear end of the roof panel 5 and is arranged below the end of the cross member that extends in the Y direction, and is a third plate that extends along the XY plane. Functions as a department. The roof back inner extension 4 has a first overlapping portion 41 extending along the YZ plane and a second overlapping portion extending along the XY plane protruding from the outer end portion in the Y direction, and the first overlapping portion 41 and the roof back inner extension 4. A notch 43 is formed between the second overlapping portion 42 and the second overlapping portion 42.

切欠き部４３は、第１重なり部４１の上端縁（Ｙ方向に沿って延びる端縁）４１１と、第２重なり部４２の後端縁（Ｙ方向に沿って延びる端縁）４２１と、上方視においてＸ方向に沿うとともに後方に向かうにしたがって下方に向かうように傾斜した底部４３１と、によって構成されている。即ち、底部４３１は、第１重なり部４１と第２重なり部４２との間においてＹ方向外側を向いた端縁である。 The cutout portion 43 is above the upper end edge (edge extending along the Y direction) 411 of the first overlapping portion 41 and the rear end edge (end edge extending along the Y direction) 421 of the second overlapping portion 42. It is composed of a bottom portion 431 that is inclined downward along the X direction in the visual direction and toward the rear. That is, the bottom portion 431 is an edge facing outward in the Y direction between the first overlapping portion 41 and the second overlapping portion 42.

ルーフパネル５は、パネル部材として機能するものであって、ＸＹ平面に沿うことで第２板部としての内側延長部３１３およびルーフバックインナエクステンション４を車外側から覆うパネル本体５１と、パネル本体５１の後端縁が下方側に屈曲されて第１板部としての本体板部２１１の一部を車外側から覆う屈曲部５２と、を有する。 The roof panel 5 functions as a panel member, and is a panel main body 51 that covers the inner extension portion 313 as the second plate portion and the roof back inner extension 4 from the outside of the vehicle along the XY plane, and the panel main body 51. It has a bent portion 52 in which the rear end edge is bent downward to cover a part of the main body plate portion 211 as the first plate portion from the outside of the vehicle.

次に、各部材の位置関係について説明する。まず、サイドボディアウタエクステンション２１のフランジ部２１２が、サイドボディアウタパネル３の上端部３１の内面部３１２に対してＹ方向内側に重ねられる。また、サイドボディアウタエクステンション２１は、内側延長部３１３に沿うように屈曲された前方延長部２１３を有しており、前方延長部２１３の上面（車外側）に内側延長部３１３が重ねられる。これにより、Ｚ方向に沿って延びる本体板部２１１と、Ｘ方向に沿って延びる前方延長部２１３及び内側延長部３１３と、によって、車外側に凸に形成されるとともにＹ方向から見てＬ字状のＬ字状角部２０が構成される。尚、Ｌ字状角部を構成する２つの部材は、いずれもが相手に沿うように屈曲されていてもよい。 Next, the positional relationship of each member will be described. First, the flange portion 212 of the side body outer extension 21 is overlapped inward in the Y direction with respect to the inner surface portion 312 of the upper end portion 31 of the side body outer panel 3. Further, the side body outer extension 21 has a front extension portion 213 bent along the inner extension portion 313, and the inner extension portion 313 is overlapped on the upper surface (outside of the vehicle) of the front extension portion 213. As a result, the main body plate portion 211 extending along the Z direction and the front extension portion 213 and the inner extension portion 313 extending along the X direction form a convex shape on the outside of the vehicle and are L-shaped when viewed from the Y direction. The L-shaped corner portion 20 is formed. It should be noted that the two members forming the L-shaped corner portion may be bent so as to be along the other side.

また、ルーフバックインナエクステンション４の第１重なり部４１が本体板部２１１の後面（車外側）に重ねられ、第２重なり部４２が内側延長部３１３の上面（車外側）に重ねられる。これにより、Ｌ字状角部２０が切欠き部４３に位置付けられ、Ｌ字状角部２０が車内側から車外側に向かって切欠き部４３を通過する。即ち、本体板部２１１および内側延長部３１３が上方または後方から見て重なり部４１、４２によってその一部が隠されるとともに、切欠き部４３においてＬ字状角部２０が露出する。 Further, the first overlapping portion 41 of the roof back inner extension 4 is overlapped on the rear surface (outside of the vehicle) of the main body plate portion 211, and the second overlapping portion 42 is overlapped on the upper surface (outside of the vehicle) of the inner extension portion 313. As a result, the L-shaped corner portion 20 is positioned at the notch portion 43, and the L-shaped corner portion 20 passes through the notch portion 43 from the inside of the vehicle to the outside of the vehicle. That is, a part of the main body plate portion 211 and the inner extension portion 313 is hidden by the overlapping portions 41 and 42 when viewed from above or rearward, and the L-shaped corner portion 20 is exposed in the notch portion 43.

また、Ｌ字状角部２０は、切欠き部４３の底部４３１に当接する。即ち、底部４３１のうち第２重なり部４２の後端縁４２１との境界部分に対し、内側延長部３１３および前方延長部２１３がＹ方向外側から当接し、底部４３１のうち第１重なり部４１の上端縁４１１との境界部分に対し、本体板部２１１がＹ方向外側から当接する。尚、Ｌ字状角部２０および切欠き部４３をＹ方向内側から見ると、内側延長部３１３および前方延長部２１３と、本体板部２１１と、底部４３１と、によって三角形状の開口が形成されている。また、切欠き部４３およびＬ字状角部２０を下方側から見ると、図５に示すように、切欠き部４３を通して前方延長部２１３が見えるようになっている。 Further, the L-shaped corner portion 20 comes into contact with the bottom portion 431 of the notch portion 43. That is, the inner extension portion 313 and the front extension portion 213 come into contact with the boundary portion of the bottom portion 431 with the rear end edge 421 of the second overlapping portion 42 from the outside in the Y direction, and the first overlapping portion 41 of the bottom portion 431 The main body plate portion 211 comes into contact with the boundary portion with the upper end edge 411 from the outside in the Y direction. When the L-shaped corner portion 20 and the notch portion 43 are viewed from the inside in the Y direction, a triangular opening is formed by the inner extension portion 313 and the front extension portion 213, the main body plate portion 211, and the bottom portion 431. ing. Further, when the notch portion 43 and the L-shaped corner portion 20 are viewed from the lower side, as shown in FIG. 5, the front extension portion 213 can be seen through the notch portion 43.

さらに、ルーフパネル５のパネル本体５１が、第２重なり部４２の上面（車外側）、及び、内側延長部３１３のうち第２重なり部４２が重ねられない部分の上面（車外側）に重ねられる。また、ルーフパネル５の屈曲部５２が、第１重なり部４１の後面（車外側）、及び、本体板部２１１のうち第１重なり部４１が重ねられない部分の上面（車が該側）に重ねられる。 Further, the panel body 51 of the roof panel 5 is overlapped on the upper surface (outside of the vehicle) of the second overlapping portion 42 and the upper surface (outside of the vehicle) of the inner extension portion 313 where the second overlapping portion 42 cannot be overlapped. .. Further, the bent portion 52 of the roof panel 5 is placed on the rear surface (outside of the vehicle) of the first overlapping portion 41 and on the upper surface (the side of the vehicle) of the main body plate portion 211 where the first overlapping portion 41 cannot be overlapped. Can be stacked.

このように各部材が重なることにより、車体角部構造１０には図６に示すように、パネル本体５１と第２重なり部４２と内側延長部３１３との３枚が上方から順に重なった第１重なり領域Ａ１、パネル本体５１と第２重なり部４２と内側延長部３１３と前方延長部２１３との４枚が上方から順に重なった第２重なり領域Ａ２、パネル本体５１と内側延長部３１３と前方延長部２１３との３枚が上方から順に重なった第３重なり領域Ａ３、及び、屈曲部５２と第１重なり部４１と本体板部２１１との３枚が後方から順に重なった第４重なり領域Ａ４が形成される。 By overlapping the members in this way, as shown in FIG. 6, the first three pieces of the panel main body 51, the second overlapping portion 42, and the inner extension portion 313 are overlapped in order from above in the vehicle body corner structure 10. The overlapping area A1, the panel body 51, the second overlapping portion 42, the inner extension portion 313, and the front extension portion 213 are overlapped in order from the top, and the second overlapping region A2, the panel body 51, the inner extension portion 313, and the front extension The third overlapping region A3 in which the three pieces of the portion 213 are overlapped in order from above, and the fourth overlapping region A4 in which the three pieces of the bent portion 52, the first overlapping portion 41, and the main body plate portion 211 are overlapped in order from the rear are It is formed.

以上のような重なり領域Ａ１〜Ａ４のそれぞれにおいて、適宜な箇所が溶接されることにより、各部材が接合される。溶接個所ＳＰの例を図４に示す。このように、パネル本体５１と第２重なり部４２と内側延長部３１３との３枚が接合され、屈曲部５２と第１重なり部４１と本体板部２１１との３枚が接合される。さらに、切欠き部４３において、パネル本体５１と、Ｌ字状角部２０を構成する内側延長部３１３および前方延長部２１３と、の３枚が接合される。 In each of the overlapping regions A1 to A4 as described above, the respective members are joined by welding appropriate portions. An example of the welded portion SP is shown in FIG. In this way, the panel main body 51, the second overlapping portion 42, and the inner extension portion 313 are joined together, and the bent portion 52, the first overlapping portion 41, and the main body plate portion 211 are joined together. Further, in the cutout portion 43, the panel main body 51 and the inner extension portion 313 and the front extension portion 213 forming the L-shaped corner portion 20 are joined to each other.

尚、製造上、溶接可能な重なり枚数が制限されることがある。例えば３枚同時の溶接が上限となる場合には、４枚が重なる第２重なり領域Ａ２においては、上方から３枚を溶接してもよいし、下方から３枚を溶接してもよいし、上方から３枚の溶接と、下方から３枚の溶接と、の両方を行ってもよい。 In manufacturing, the number of overlapping sheets that can be welded may be limited. For example, when the upper limit is the simultaneous welding of three sheets, in the second overlapping region A2 where four sheets overlap, three sheets may be welded from above, or three sheets may be welded from below. Both welding of three pieces from the top and welding of three pieces from the bottom may be performed.

また、上記のような溶接は、リアピラー２に対するリアピラーインナリンフォース６の取り付けの前後いずれにおいて行ってもよい。取り付け後に溶接する場合、リアピラーインナリンフォース６の適宜な開口部に溶接用のガンを挿通すればよい。ここで、開口部６１は、図７に示すように、リアピラーインナリンフォース６のうち切欠き部４３の底部４３１に沿って傾斜した部分に形成されており、一点鎖線で示すように溶接用のガンを挿通することができ、Ｌ字状角部２０を溶接しやすくなっている。 Further, the above welding may be performed before or after the attachment of the rear pillar inner force 6 to the rear pillar 2. When welding after mounting, a welding gun may be inserted through an appropriate opening of the rear pillar inner force 6. Here, as shown in FIG. 7, the opening 61 is formed in a portion of the rear pillar inner force 6 that is inclined along the bottom portion 431 of the notch portion 43, and is formed for welding as shown by the alternate long and short dash line.

車体角部構造１０において、以下に説明するように各部材間の第１〜第３シーリング部Ｓ１〜Ｓ３にシール部材が設けられ、車外の水が部材間を通過して車内に向かうことが抑制される。第１シーリング部Ｓ１は、内面部３１２と内側延長部３１３との境界であり且つ内側延長部３１３のうち第２重なり部４２の外側に沿った部分であり、主としてパネル本体５１と内面部３１２との間の止水を目的としている。第２シーリング部Ｓ２は、第１シーリング部Ｓ１の後端に連続するとともに、内面部３１２のうちフランジ部２１２の外側に沿った部分であり、主として上端部３１とサイドボディアウタエクステンション２１との間の止水を目的としている。第３シーリング部Ｓ３は、第１シーリング部Ｓ１の後端に連続するとともに、本体板部２１１のうち第１重なり部４１の外側に沿った部分であり、主として屈曲部５２とサイドボディアウタエクステンション２１との間の止水を目的としている。また、第１シーリング部Ｓ１および第３シーリング部Ｓ３は、ルーフパネル５の外縁に沿っている。 In the vehicle body corner structure 10, seal members are provided in the first to third sealing portions S1 to S3 between the members as described below to prevent water outside the vehicle from passing between the members and heading into the vehicle. Will be done. The first sealing portion S1 is a boundary between the inner surface portion 312 and the inner surface portion 313 and is a portion of the inner extension portion 313 along the outer side of the second overlapping portion 42, and is mainly composed of the panel main body 51 and the inner surface portion 312. The purpose is to stop the water between. The second sealing portion S2 is continuous with the rear end of the first sealing portion S1 and is a portion of the inner surface portion 312 along the outside of the flange portion 212, and is mainly between the upper end portion 31 and the side body outer extension 21. The purpose is to stop the water. The third sealing portion S3 is continuous with the rear end of the first sealing portion S1 and is a portion of the main body plate portion 211 along the outside of the first overlapping portion 41, and is mainly a bent portion 52 and a side body outer extension 21. The purpose is to stop the water between. Further, the first sealing portion S1 and the third sealing portion S3 are along the outer edge of the roof panel 5.

このような本実施例によれば、以下のような効果がある。即ち、本体板部２１１および内側延長部３１３によって構成されるＬ字状角部２０が、車内側から車外側に向かってルーフバックインナエクステンション４の切欠き部４３を通過することで、Ｌ字状角部２０が第１重なり部４１と第２重なり部４２とによって挟み込まれる。ここで、第１重なり部４１が本体板部２１１に接合され、第２重なり部４２が内側延長部３１３に接合されることにより、Ｌ字状角部２０の移動（特にＬ字状角部２０が挟み込まれる方向の移動）が抑制される。また、Ｌ字状角部２０が切欠き部４３の底部４３１に当接することで、Ｌ字状角部２０がルーフバックインナエクステンション４に近づくことが規制される。このようにＬ字状角部２０の移動が抑制されることで、３面が交差した角部の変形を抑制することができる。 According to this embodiment, there are the following effects. That is, the L-shaped corner portion 20 composed of the main body plate portion 211 and the inner extension portion 313 passes through the notch portion 43 of the roofback inner extension 4 from the inside of the vehicle to the outside of the vehicle, thereby forming an L-shape. The corner portion 20 is sandwiched between the first overlapping portion 41 and the second overlapping portion 42. Here, the first overlapping portion 41 is joined to the main body plate portion 211, and the second overlapping portion 42 is joined to the inner extension portion 313 to move the L-shaped corner portion 20 (particularly, the L-shaped corner portion 20). Movement in the direction in which is sandwiched) is suppressed. Further, when the L-shaped corner portion 20 comes into contact with the bottom portion 431 of the notch portion 43, the L-shaped corner portion 20 is restricted from approaching the roof back inner extension 4. By suppressing the movement of the L-shaped corner portion 20 in this way, it is possible to suppress the deformation of the corner portion where the three surfaces intersect.

このように３面が交差した角部の変形を抑制することにより、各部材とルーフパネル５との間に設けられたシール部材の割れや剥離を抑制することができる。 By suppressing the deformation of the corners where the three surfaces intersect in this way, it is possible to suppress cracking and peeling of the seal member provided between each member and the roof panel 5.

また、パネル本体５１と第２重なり部４２と内側延長部３１３との３枚が接合され、屈曲部５２と第１重なり部４１と本体板部２１１との３枚が接合されることにより、Ｌ字状角部２０を挟む位置においてルーフパネル５が各部材と接合される。さらに、ルーフパネル５がＬ字状角部２０に接合されている。これにより、Ｌ字状角部２０への応力集中を抑制し、３部材が接合される角部の変形を抑制することができる。このように変形を抑制することにより、ルーフパネル５と他の部材との間に隙間が生じにくく、シール性を向上させることができる。 Further, the panel main body 51, the second overlapping portion 42, and the inner extension portion 313 are joined to each other, and the bent portion 52, the first overlapping portion 41, and the main body plate portion 211 are joined to form L. The roof panel 5 is joined to each member at a position sandwiching the character corner portion 20. Further, the roof panel 5 is joined to the L-shaped corner portion 20. As a result, stress concentration on the L-shaped corner portion 20 can be suppressed, and deformation of the corner portion to which the three members are joined can be suppressed. By suppressing the deformation in this way, a gap is less likely to occur between the roof panel 5 and other members, and the sealing property can be improved.
