Description

本発明は、車両用ルーフの開口構造に関する。   The present invention relates to an opening structure of a vehicle roof.

従来から、開口部が設けられた車両用ルーフにおいて、該開口部の剛性低下を抑制する技術が知られている（例えば、特許文献１参照）。   Conventionally, in a vehicle roof provided with an opening, a technique for suppressing a decrease in rigidity of the opening is known (for example, see Patent Document 1).

特許文献１は、サンルーフユニットの基枠体をルーフの開口部に取り付けたルーフ骨格構造を開示している。   Patent Document 1 discloses a roof skeleton structure in which a base frame body of a sunroof unit is attached to an opening of a roof.

特開２０１２−４０９９９号公報JP 2012-40999 A

上記ルーフ骨格構造は、補強部材としての基枠体を開口部に設置することにより該開口部の剛性を向上させているが、補剛効率が低いために車両重量が増加するという問題があった。   The roof skeleton structure improves the rigidity of the opening by installing a base frame body as a reinforcing member in the opening, but there is a problem that the vehicle weight increases due to low stiffening efficiency. .

本発明は、上記問題に鑑みてなされたものであり、その目的は、ルーフの開口部を効率的に補剛して、補強部材の設置による車両重量の増加を抑制することにある。   The present invention has been made in view of the above problems, and an object thereof is to efficiently stiffen the opening of the roof and suppress an increase in the vehicle weight due to the installation of the reinforcing member.

本発明の一態様は、ルーフパネルに形成されたビード部の開断面と、ルーフパネルの開口の周縁部に沿って延設された補強部材の閉断面とを連結した車両用ルーフの開口構造である。   One aspect of the present invention is a vehicle roof opening structure in which an open cross-section of a bead portion formed on a roof panel and a closed cross-section of a reinforcing member extending along a peripheral edge of the roof panel opening are connected. is there.

上記開口構造によれば、ビード部の開断面と補強部材の閉断面とが連結されているので、ビード部に入力された荷重（ルーフの変形荷重）が効率よく補強部材に伝達される。これにより、ルーフの開口部を効率的に補剛することができ、補強部材の設置による車両重量の増加を抑制することができる。   According to the above opening structure, since the open cross section of the bead portion and the closed cross section of the reinforcing member are connected, the load (roof deformation load) input to the bead portion is efficiently transmitted to the reinforcing member. Thereby, the opening part of a roof can be stiffened efficiently and the increase in the vehicle weight by installation of a reinforcement member can be suppressed.

本実施形態にかかる開口構造は、図１，２に示すように、車両のルーフ１を構成するルーフパネル３と、ルーフパネル３に取り付けられた閉断面構造の枠部材（補強部材）５と、を備えている。ルーフパネル３の車幅方向両側端縁は、それぞれ左右のルーフサイドレール７に接合されている。ルーフパネル３の中央部には、平面視において略矩形状の開口９（以下、パネル開口９と称する）が設けられており、このパネル開口９の周縁部に、枠部材５が取り付けられている。   As shown in FIGS. 1 and 2, the opening structure according to the present embodiment includes a roof panel 3 constituting a vehicle roof 1, a frame member (reinforcing member) 5 having a closed cross-sectional structure attached to the roof panel 3, and It has. Both side edges in the vehicle width direction of the roof panel 3 are joined to the left and right roof side rails 7, respectively. A substantially rectangular opening 9 (hereinafter referred to as a panel opening 9) is provided in the center of the roof panel 3 in plan view, and a frame member 5 is attached to the peripheral edge of the panel opening 9. .

ルーフパネル３には、図１，２に示すように、車両前後方向（以下、ビード延在方向ともいう）に略直線状に延在する開断面構造の凸ビード（ビード部）１１が複数形成されている。本実施形態では、６本の凸ビード１１Ａ，１１Ｂ，１１Ｃ，１１Ｄ，１１Ｅ，１１Ｆが、互いの間に所定の間隔を設けつつ車両左側から車両右側に向かう方向にこの順で並列している。なお、本明細書では、これら６本の凸ビードを凸ビード１１と総称する。ルーフパネル３の下面には、車幅方向に延在するルーフボウ１３が複数箇所（本実施形態では、３箇所）に取り付けられている。各ルーフボウ１３の左右両端部は、それぞれ左右のルーフサイドレール７に連結されている。   As shown in FIGS. 1 and 2, the roof panel 3 is formed with a plurality of convex beads (bead portions) 11 having an open cross-sectional structure extending substantially linearly in the vehicle longitudinal direction (hereinafter also referred to as a bead extending direction). Has been. In the present embodiment, the six convex beads 11A, 11B, 11C, 11D, 11E, and 11F are arranged in parallel in this order from the left side of the vehicle toward the right side of the vehicle while providing a predetermined interval therebetween. In the present specification, these six convex beads are collectively referred to as convex beads 11. On the lower surface of the roof panel 3, roof bows 13 extending in the vehicle width direction are attached at a plurality of locations (three locations in the present embodiment). The left and right ends of each roof bow 13 are connected to the left and right roof side rails 7, respectively.

各凸ビード１１は、図３（ａ）に示すように、ビード延在方向に垂直な断面において、下方に向けて開口する略ハット形状の開断面を有している。具体的には、各凸ビード１１は、各々下端がルーフ上面壁３ａに連結された左右の傾斜壁１１ａ，１１ｂと、ルーフ上面壁３ａと略平行に延在して左右の傾斜壁１１ａ，１１ｂの上端同士を連結するビード上面壁１１ｃとを備えている。左傾斜壁１１ａは、ビード上面壁１１ｃの左側端から左下方に向けて傾斜して延在しており、右傾斜壁１１ｂは、ビード上面壁１１ｃの右側端から右下方に向けて傾斜して延在している。   As shown in FIG. 3A, each convex bead 11 has a substantially hat-shaped open cross section that opens downward in a cross section perpendicular to the bead extending direction. Specifically, each convex bead 11 has left and right inclined walls 11a and 11b each having a lower end connected to the roof upper surface wall 3a, and the left and right inclined walls 11a and 11b extending substantially parallel to the roof upper surface wall 3a. And a bead upper surface wall 11c for connecting the upper ends of the two. The left inclined wall 11a extends inclined from the left end of the bead upper surface wall 11c toward the lower left, and the right inclined wall 11b is inclined toward the lower right from the right end of the bead upper surface wall 11c. It is extended.

左傾斜壁１１ａは、ビード延在方向に垂直な断面において、左上に凸となるように滑らかに湾曲した左上側曲面部１１ａｕと、右下に凸となるように滑らかに湾曲した左下側曲面部１１ａｌとからなる。左上側曲面部１１ａｕの上端（右端）は、ビード上面壁１１ｃの左端に滑らかに接続されており、左下側曲面部１１ａｌの下端（左端）は、ルーフ上面壁３ａの右端に滑らかに接続されている。   In the cross section perpendicular to the bead extending direction, the left inclined wall 11a includes a left upper curved surface portion 11au that is smoothly curved so as to protrude upward and a lower left curved surface portion that is smoothly curved so as to protrude downward to the right 11al. The upper end (right end) of the upper left curved surface portion 11au is smoothly connected to the left end of the bead upper surface wall 11c, and the lower end (left end) of the lower left curved surface portion 11al is smoothly connected to the right end of the roof upper surface wall 3a. Yes.

また、右傾斜壁１１ｂは、ビード延在方向に垂直な断面において、右上に凸となるように滑らかに湾曲した右上側曲面部１１ｂｕと、左下に凸となるように滑らかに湾曲した右下側曲面部１１ｂｌとからなる。右上側曲面部１１ｂｕの上端（左端）は、ビード上面壁１１ｃの右端に滑らかに接続されており、右下側曲面部１１ｂｌの下端（右端）は、ルーフ上面壁３ａの左端に滑らかに接続されている。   The right inclined wall 11b has a right upper curved surface portion 11bu that is smoothly curved so as to be convex upward and a right lower side that is smoothly curved so as to be convex downward in the cross section perpendicular to the bead extending direction. It consists of a curved surface part 11bl. The upper end (left end) of the upper right curved surface portion 11bu is smoothly connected to the right end of the bead upper surface wall 11c, and the lower end (right end) of the lower right curved surface portion 11bl is smoothly connected to the left end of the roof upper surface wall 3a. ing.

ここで、ビード延在方向に垂直な断面（図３（ａ））において、凸ビード１１を構成する各壁部１１ａ（１１ａｕ，１１ａｌ），１１ｂ（１１ｂｕ，１１ｂｌ），１１ｃの曲率に着目すると、それらの曲率は、各壁部同士の接続点Ｐ１〜Ｐ６を境に大きく変化している。例えば、ルーフ上面壁３ａと左傾斜壁１１ａの左下側曲面部１１ａｌとの接続点Ｐ１では、ルーフ上面壁３ａで略ゼロであった曲率が、接続点Ｐ１を境に、左下側曲面部１１ａｌで正の曲率になる。なお、本明細書では、ビード延在方向に垂直な断面において、下向きに凸になる曲率を正の曲率とする。また、左下側曲面部１１ａｌと左上側曲面部１１ａｕとの接続点Ｐ２においても、左下側曲面部１１ａｌで正の値であった曲率が、接続点Ｐ２を境に、左上側曲面部１１ａｕで負の曲率になる。さらに、左上側曲面部１１ａｕとビード上面壁１１ｃとの接続点Ｐ３においても、左上側曲面部１１ａｕで負の値であった曲率が、接続点Ｐ３を境に、ビード上面壁１１ｃで略ゼロの曲率になる。同様に、ルーフ上面壁３ａと右傾斜壁１１ｂの右下側曲面部１１ｂｌとの接続点Ｐ６、右下側曲面部１１ｂｌと右上側曲面部１１ｂｕとの接続点Ｐ５、及び、右上側曲面部１１ｂｕとビード上面壁１１ｃとの接続点Ｐ４においても大きく曲率が変化している。   Here, in the cross section perpendicular to the bead extending direction (FIG. 3A), attention is paid to the curvature of each of the wall portions 11a (11au, 11al), 11b (11bu, 11bl), 11c constituting the convex bead 11. Those curvatures change greatly with the connection points P1 to P6 between the walls. For example, at the connection point P1 between the roof upper surface wall 3a and the lower left curved surface portion 11al of the left inclined wall 11a, the curvature that was substantially zero at the roof upper surface wall 3a is the boundary between the connection point P1 and the lower left curved surface portion 11al. Positive curvature. In the present specification, a curvature that protrudes downward in a cross section perpendicular to the bead extending direction is defined as a positive curvature. Further, also at the connection point P2 between the lower left curved surface portion 11al and the upper left curved surface portion 11au, the curvature that was a positive value at the lower left curved surface portion 11al is negative at the upper left curved surface portion 11au from the connection point P2. Of curvature. Further, also at the connection point P3 between the upper left curved surface portion 11au and the bead upper surface wall 11c, the curvature, which is a negative value at the upper left curved surface portion 11au, is substantially zero at the bead upper surface wall 11c with the connection point P3 as a boundary. Become curvature. Similarly, the connection point P6 between the roof upper surface wall 3a and the lower right curved surface portion 11bl of the right inclined wall 11b, the connection point P5 between the lower right curved surface portion 11bl and the upper right curved surface portion 11bu, and the upper right curved surface portion 11bu. The curvature also greatly changes at a connection point P4 between the bead upper surface wall 11c.

上記の各接続点Ｐ１〜Ｐ６は、ビード延在方向に連続して存在している。ここでは、図３（ｂ）に示すように、連続する接続点Ｐ１によって形成される線を稜線Ｌ１と、連続する接続点Ｐ２によって形成される線を稜線Ｌ２と、連続する接続点Ｐ３によって形成される線を稜線Ｌ３と呼ぶ。また、連続する接続点Ｐ４によって形成される線を稜線Ｌ４と、連続する接続点Ｐ５によって形成される線を稜線Ｌ５と、連続する接続点Ｐ６によって形成される線を稜線Ｌ６と呼ぶ。各稜線Ｌ１〜Ｌ６は、互いに交わることなく、ビード延在方向に略平行に延在する。補剛部材としての凸ビード１１の幅は、ビード延在方向に垂直な方向において互いに最も離れた位置にある２本の稜線によって規定される。すなわち、最も左側に位置する稜線Ｌ１と最も右側に位置する稜線Ｌ６とに挟まれた部分が凸ビード１１に相当する。   Each said connection point P1-P6 exists continuously in the bead extension direction. Here, as shown in FIG. 3B, a line formed by the continuous connection point P1 is formed by the ridge line L1, and a line formed by the continuous connection point P2 is formed by the ridge line L2 and the continuous connection point P3. This line is called a ridge line L3. A line formed by the continuous connection point P4 is referred to as a ridge line L4, a line formed by the continuous connection point P5 is referred to as a ridge line L5, and a line formed by the continuous connection point P6 is referred to as a ridge line L6. Each ridgeline L1-L6 extends substantially parallel to the bead extension direction without intersecting each other. The width of the convex bead 11 as a stiffening member is defined by two ridgelines that are farthest from each other in the direction perpendicular to the bead extending direction. That is, a portion sandwiched between the ridge line L1 located on the leftmost side and the ridgeline L6 located on the rightmost side corresponds to the convex bead 11.

また、図３（ａ）に示すように、凸ビード１１において、左右の傾斜壁１１ａ，１１ｂの下端の稜線Ｌ１，Ｌ６の間に張られる仮想の面を凸ビード１１の開口面ＳＢとして規定する。そして、ビード延在方向に垂直な断面において、開口面ＳＢと左右の傾斜壁１１ａ，１１ｂとビード上面壁１１ｃとによって囲まれた領域（図３（ａ）の斜線部分）を、凸ビード１１の「開断面ＯＳ」とする。また、開口面ＳＢよりも上側において、左右の傾斜壁１１ａ，１１ｂとビード上面壁１１ｃとによって左右及び上方の三方を囲まれた、車両前後方向に延びる空間領域を、凸ビード１１の「開断面領域ＯＲ」とする。この凸ビード１１の開断面領域ＯＲは、いわば複数の稜線Ｌ１〜Ｌ６によって囲まれた領域である。   Further, as shown in FIG. 3A, in the convex bead 11, an imaginary surface stretched between the ridge lines L <b> 1 and L <b> 6 at the lower ends of the left and right inclined walls 11 a and 11 b is defined as the opening surface SB of the convex bead 11. . Then, in a cross section perpendicular to the bead extending direction, a region surrounded by the opening surface SB, the left and right inclined walls 11a and 11b, and the bead upper surface wall 11c (the hatched portion in FIG. 3A) is formed on the convex bead 11. This is referred to as “open cross-sectional OS”. Further, on the upper side of the opening surface SB, a spatial region extending in the vehicle front-rear direction surrounded by the left and right inclined walls 11a, 11b and the bead upper surface wall 11c is defined as “open section” of the convex bead 11. Region OR ”. The open cross-sectional area OR of the convex beads 11 is an area surrounded by a plurality of ridgelines L1 to L6.

一般に、ルーフパネルのようなパネル材に上記稜線を設けることで、該稜線の延在方向におけるパネル材の剛性及び強度を増加させることができる。各凸ビード１１には、図３に示すように、車両前後方向に連続して延在する複数の稜線Ｌ１〜Ｌ６が集合しているので、各凸ビード１１は、それぞれルーフパネル３に車両前後方向の剛性及び強度を付与する強度部材として機能する。さらに開断面領域ＯＲは、凸ビード１１の形成に伴って形成されるものであるから、各開断面領域ＯＲ自体を、ルーフパネル３に剛性及び強度を付与する構成要素として捉えることもできる。   Generally, by providing the ridge line on a panel material such as a roof panel, the rigidity and strength of the panel material in the extending direction of the ridge line can be increased. As shown in FIG. 3, a plurality of ridge lines L <b> 1 to L <b> 6 that continuously extend in the vehicle front-rear direction are gathered in each convex bead 11, so that each convex bead 11 is respectively attached to the roof panel 3 in the vehicle front-rear direction. It functions as a strength member that gives direction rigidity and strength. Furthermore, since the open cross-sectional area OR is formed along with the formation of the convex bead 11, each open cross-sectional area OR itself can be regarded as a component that gives the roof panel 3 rigidity and strength.

また、パネル開口９は、図２に示すように、前側周縁部９ａ、後側周縁部９ｂ、左側周縁部９ｃ及び右側周縁部９ｄによって４辺を囲まれている。前側周縁部９ａ及び後側周縁部９ｂは、それぞれパネル開口９の前側及び後側において車幅方向に直線状に延在している。左側周縁部９ｃは、前側及び後側周縁部９ａ，９ｂの左側端部を連結して車両前後方向に延在している。右側周縁部９ｄは、前側及び後側周縁部９ａ，９ｂの右側端部を連結して車両前後方向に延在している。   Further, as shown in FIG. 2, the panel opening 9 is surrounded by four sides by a front peripheral edge 9a, a rear peripheral edge 9b, a left peripheral edge 9c, and a right peripheral edge 9d. The front peripheral edge portion 9a and the rear peripheral edge portion 9b extend linearly in the vehicle width direction on the front side and the rear side of the panel opening 9, respectively. The left peripheral edge portion 9c extends in the vehicle front-rear direction by connecting the left end portions of the front and rear peripheral edge portions 9a, 9b. The right peripheral edge portion 9d extends in the vehicle front-rear direction by connecting the right end portions of the front and rear peripheral edge portions 9a, 9b.

また、各凸ビード１１は、図２，３（ｂ）に示すように、パネル開口９により寸断されており、凸ビード１１の各稜線Ｌ１〜Ｌ６及び開断面領域ＯＲも、パネル開口９によって寸断されている。ここで寸断とは、長く連続して延在するものを途中で切断することを意味する。本実施形態では、特に、各凸ビード１１を前後に分断することを指す。   As shown in FIGS. 2 and 3B, each convex bead 11 is cut by the panel opening 9, and each ridge line L <b> 1 to L <b> 6 and the open cross-sectional area OR of the convex bead 11 is also cut by the panel opening 9. Has been. Here, the term “cutting” means that a long continuous piece is cut in the middle. In this embodiment, in particular, it points out dividing each convex bead 11 back and forth.

具体的には、図１，２に示すように、凸ビード１１Ａは、前側凸ビード１１Ａｆと後側凸ビード１１Ａｒに、凸ビード１１Ｂは、前側凸ビード１１Ｂｆと後側凸ビード１１Ｂｒに、凸ビード１１Ｃは、前側凸ビード１１Ｃｆと後側凸ビード１１Ｃｒにそれぞれ分断される。同様に、凸ビード１１Ｄは、前側凸ビード１１Ｄｆと後側凸ビード１１Ｄｒに、凸ビード１１Ｅは、前側凸ビード１１Ｅｆと後側凸ビード１１Ｅｒに、凸ビード１１Ｆは、前側凸ビード１１Ｆｆと後側凸ビード１１Ｆｒにそれぞれ分断される。前側及び後側凸ビード１１Ａｆ〜１１Ｆｆ，１１Ａｒ〜１１Ｆｒは、それぞれパネル開口９を挟んで同一直線上に延在することとなる。   Specifically, as shown in FIGS. 1 and 2, the convex bead 11 </ b> A is formed on the front convex bead 11 </ b> Af and the rear convex bead 11 </ b> Ar, and the convex bead 11 </ b> B is formed on the front convex bead 11 </ b> Bf and the rear convex bead 11 </ b> Br. 11C is divided into a front convex bead 11Cf and a rear convex bead 11Cr. Similarly, the convex bead 11D is a front convex bead 11Df and a rear convex bead 11Dr, the convex bead 11E is a front convex bead 11Ef and a rear convex bead 11Er, and the convex bead 11F is a front convex bead 11Ff and a rear convex. Each bead 11Fr is divided. The front and rear convex beads 11 </ b> Af to 11 </ b> Ff and 11 </ b> Ar to 11 </ b> Fr respectively extend on the same straight line across the panel opening 9.

また、寸断された各凸ビード１１は、図３（ｂ）に示すように、それぞれパネル開口９の周縁まで連続して延在しており、凸ビード１１の稜線Ｌ１〜Ｌ６や開断面領域ＯＲも、パネル開口９の周縁まで連続して延在している。   In addition, as shown in FIG. 3B, each of the cut convex beads 11 extends continuously to the peripheral edge of the panel opening 9, and the ridge lines L <b> 1 to L <b> 6 of the convex beads 11 and the open cross-sectional area OR Also, it extends continuously to the peripheral edge of the panel opening 9.

枠部材５は、図４に示すように、平面視において略矩形環形状を有しており、その内周縁部によって略矩形状の開口５ａを形成している。開口５ａには、図２，５に示すように、サンルーフガラス１５がはめ込まれており、サンルーフガラス１５の外周縁部１５ａが枠部材５の内周縁部に接着剤１７により固定されている。サンルーフガラス１５と枠部材５との間には、シール材１９が介在しており、車両外部からの雨水等の水の侵入を防止している。   As shown in FIG. 4, the frame member 5 has a substantially rectangular ring shape in a plan view, and a substantially rectangular opening 5 a is formed by the inner peripheral edge portion thereof. As shown in FIGS. 2 and 5, the sunroof glass 15 is fitted into the opening 5 a, and the outer peripheral edge 15 a of the sunroof glass 15 is fixed to the inner peripheral edge of the frame member 5 with an adhesive 17. A sealing material 19 is interposed between the sunroof glass 15 and the frame member 5 to prevent intrusion of water such as rainwater from the outside of the vehicle.

That is, the front convex bead 11Af, the rear convex bead 11Ar, and the left side 5C are arranged on the same straight line extending in the vehicle front-rear direction. Further, the front convex bead 11Ff, the rear convex bead 11Fr, and the right side portion 5D are arranged on the same straight line extending in the vehicle front-rear direction.

より詳細には、図１１に示すように、前側凸ビード１１Ａｆの稜線Ｌ１の後方への延長線Ｌ１Ｅが、左辺部５Ｃの閉断面領域ＣＲの車両前後方向に垂直な断面における幅（閉断面ＣＳの幅）Ｗの範囲内に位置している。同様に、後側凸ビード１１Ａｒの稜線Ｌ１の前方への延長線Ｌ１Ｅが、左辺部５Ｃの閉断面領域ＣＲの車両前後方向に垂直な断面における幅（閉断面ＣＳの幅）の範囲内に位置している。図示は省略するが、右辺部５Ｄにおいても同様に、前側凸ビード１１Ｆｆ及び後側凸ビード１１Ｆｒの稜線Ｌ６の延長線Ｌ６Ｅが、右辺部５Ｄの閉断面領域ＣＲの車両前後方向に垂直な断面における幅（閉断面ＣＳの幅）Ｗの範囲内に位置している。ここで幅とは、水平方向の幅を意味する。   More specifically, as shown in FIG. 11, an extension line L1E to the rear of the ridge line L1 of the front convex bead 11Af is a width (closed section CS) in a section perpendicular to the vehicle longitudinal direction of the closed section region CR of the left side portion 5C. The width is within the range of W. Similarly, the forward extension line L1E of the ridge line L1 of the rear convex bead 11Ar is located within the range of the width (the width of the closed section CS) in the section perpendicular to the vehicle front-rear direction of the closed section region CR of the left side portion 5C. doing. Although illustration is omitted, similarly, in the right side portion 5D, the extension line L6E of the ridge line L6 of the front convex bead 11Ff and the rear convex bead 11Fr is in a cross section perpendicular to the vehicle longitudinal direction of the closed cross-sectional area CR of the right side portion 5D. It is located within the range of the width (width of the closed section CS) W. Here, the width means a width in the horizontal direction.

以下に、本実施形態による作用効果を説明する。   Below, the effect by this embodiment is demonstrated.

本実施形態にかかる車両用ルーフの開口構造によれば、ルーフパネル３に形成された凸ビード１１の開断面ＯＳと、パネル開口９の周縁部に沿って延設された枠部材５の閉断面ＣＳとが連結されているので、凸ビード１１に入力された荷重（ルーフ１の変形荷重）が効率よく枠部材５に伝達される。これにより、ルーフ１の開口部を効率的に補剛することができ、枠部材５の設置による車両重量の増加を抑制することができる。特に、凸ビード１１がパネル開口９によって寸断される構造のルーフ１においては、パネル開口９の形成によって低下するルーフ１の剛性を効率的に補うことができる。   According to the opening structure of the vehicle roof according to the present embodiment, the open cross section OS of the convex beads 11 formed in the roof panel 3 and the closed cross section of the frame member 5 extending along the peripheral edge of the panel opening 9. Since CS is connected, the load (the deformation load of the roof 1) input to the convex bead 11 is efficiently transmitted to the frame member 5. Thereby, the opening part of the roof 1 can be stiffened efficiently, and the increase in the vehicle weight by installation of the frame member 5 can be suppressed. In particular, in the roof 1 having a structure in which the convex beads 11 are cut off by the panel openings 9, the rigidity of the roof 1 that is reduced by the formation of the panel openings 9 can be efficiently compensated.

また、本実施形態では、前側凸ビード１１Ａｆ及び後側凸ビード１１Ａｒの稜線Ｌ１の延長線Ｌ１Ｅが、ビード延在方向と直交する方向において、枠部材５の左辺部５Ｃの閉断面ＣＳの幅の範囲内に位置しており、かつ、左辺部５Ｃがビード延在方向と平行に延在している。そのため、枠部材５の閉断面領域ＣＲが、凸ビード１１Ａの稜線Ｌ１の延長線Ｌ１Ｅと少なくとも左辺部５Ｃの長さに亘ってラップしている（つまり、左辺部５Ｃと凸ビード１１Ａとがビード延在方向に沿って同一直線上に並んでいる）。また、図示は省略するが、前側凸ビード１１Ｆｆ及び後側凸ビード１１Ｆｒの稜線Ｌ６の延長線Ｌ６Ｅも、ビード延在方向と直交する方向において、枠部材５の右辺部５Ｄの閉断面ＣＳの幅の範囲内に位置しており、かつ、右辺部５Ｄがビード延在方向と平行に延在している。そのため、枠部材５の閉断面領域ＣＲが、凸ビード１１Ｆの稜線Ｌ６の延長線Ｌ６Ｅと少なくとも右辺部５Ｄの長さに亘ってラップしている（つまり、右辺部５Ｄと凸ビード１１Ｆとがビード延在方向に沿って同一直線上に並んでいる）。これにより、凸ビード１１（特に、凸ビード１１Ａ，１１Ｆ）に入力された荷重（ルーフ１の変形荷重）が一層効率よく枠部材５に伝達されるので、ルーフ１の開口部をさらに効率的に補剛して、車両重量の増加をさらに抑制することができる。   Further, in the present embodiment, the extension line L1E of the ridge line L1 of the front convex bead 11Af and the rear convex bead 11Ar is the width of the closed section CS of the left side portion 5C of the frame member 5 in the direction orthogonal to the bead extending direction. The left side 5C is located in the range and extends in parallel with the bead extending direction. Therefore, the closed cross-sectional area CR of the frame member 5 is wrapped over the extension line L1E of the ridge line L1 of the convex bead 11A and at least the length of the left side part 5C (that is, the left side part 5C and the convex bead 11A are beaded). Are aligned along the direction of extension). Although not shown, the width L6E of the ridge line L6 of the front convex bead 11Ff and the rear convex bead 11Fr is also the width of the closed section CS of the right side 5D of the frame member 5 in the direction orthogonal to the bead extending direction. The right side portion 5D extends in parallel with the bead extending direction. Therefore, the closed cross-sectional area CR of the frame member 5 is wrapped over the extension line L6E of the ridge line L6 of the convex bead 11F and at least the length of the right side part 5D (that is, the right side part 5D and the convex bead 11F are beaded). Are aligned along the direction of extension). Thereby, the load (deformation load of the roof 1) input to the convex beads 11 (particularly, the convex beads 11A and 11F) is transmitted to the frame member 5 more efficiently, so that the opening of the roof 1 can be more efficiently opened. By stiffening, an increase in vehicle weight can be further suppressed.

なお、凸ビード１１の稜線の延長線を、ビード延在方向と直交する方向における右辺部５Ｄまたは左辺部５Ｃの閉断面ＣＳの鉛直方向の幅（高さ）の範囲内に位置させると、凸ビード１１に入力された荷重がさらに効率的に枠部材５に伝達されるので、より高い補剛効率を得ることができる。さらに、凸ビード１１の稜線の延長線を、右辺部５Ｄまたは左辺部５Ｃにおける閉断面領域ＣＲの内部を貫通するように位置させると、ビード延在方向に入力された荷重は、より直線的に伝達されるので、入力荷重に対してさらに高い補剛効率を得ることができる。   If the extended line of the ridge line of the convex bead 11 is positioned within the range of the width (height) in the vertical direction of the closed section CS of the right side part 5D or the left side part 5C in the direction orthogonal to the bead extending direction, Since the load input to the bead 11 is transmitted to the frame member 5 more efficiently, higher stiffening efficiency can be obtained. Further, when the extension line of the ridge line of the convex bead 11 is positioned so as to penetrate the inside of the closed cross-sectional area CR in the right side part 5D or the left side part 5C, the load input in the bead extending direction is more linear. Since it is transmitted, higher stiffening efficiency can be obtained with respect to the input load.

さらに、本実施形態では、車両前後方向に剛性及び強度を付与された凸ビード１１を、同じく車両前方向に剛性及び強度を付与されたビード結合部５７に結合しているので、車両前後方向に入力される荷重に対する剛性を、より向上させることができる。   Furthermore, in this embodiment, the convex bead 11 given rigidity and strength in the vehicle front-rear direction is coupled to the bead coupling portion 57 also given rigidity and strength in the vehicle front direction, so The rigidity with respect to the input load can be further improved.

Was directly connected to the closed section CS. However, the connection form of the open cross-section OS and the closed cross-section CS is not limited to this, and the open cross-section OS and the closed cross-section CS may be connected via another member having an open cross-section structure or a closed cross-section structure.

The other member may be provided integrally with the convex bead 11 or the frame member 5 or may be provided separately from them.

また、上記実施形態では、凸ビード１１の延在方向を車両前後方向としていたが、凸ビード１１の延在方向は、要求される仕様に応じて適宜設定することができる。   Moreover, in the said embodiment, although the extending direction of the convex bead 11 was made into the vehicle front-back direction, the extending direction of the convex bead 11 can be suitably set according to the specification requested | required.

さらに、凸ビード１１及び枠部材５のビード結合部５７は、ビード延在方向に垂直な断面において、下方に向けて開口する略ハット形状の断面を有していたが、それらの形状は特に限定されず、例えば、Λ型、逆Ｕ字状、互いに接続された複数の直辺部からなる多角形状、或いはそれらの組み合わせなどであってもよい。また、稜線の数も特に限定されず、５本以下であってもよく、７本以上であってもよい。当該断面の形状が直辺部のみからなる多角形状である場合など、稜線を定義することが困難な形状である場合は、断面の屈曲点によって形成される折れ線を稜線に代用してもよい。   Furthermore, the convex bead 11 and the bead coupling portion 57 of the frame member 5 have a substantially hat-shaped cross section that opens downward in a cross section perpendicular to the bead extending direction, but these shapes are particularly limited. For example, it may be a Λ shape, an inverted U shape, a polygonal shape composed of a plurality of straight sides connected to each other, or a combination thereof. Also, the number of ridge lines is not particularly limited, and may be 5 or less, or 7 or more. When the shape of the cross section is a polygonal shape including only the right side portion or the like, it is possible to substitute the ridge line formed by the bending point of the cross section for the ridge line when it is difficult to define the ridge line.

また、枠部材５の断面形状も、上記実施形態のものに限らない。例えば、枠部材５の上面は、開口周壁部５１ｂは省略してフラットな形状としてもよい。   Further, the cross-sectional shape of the frame member 5 is not limited to that of the above embodiment. For example, the upper surface of the frame member 5 may have a flat shape by omitting the opening peripheral wall portion 51b.

さらに、上記実施形態では、本発明を箱型の車両に適用した例を説明したが、車両の形状は特に限定されず、ステーションワゴンなど他の形状の車両にも本発明を適用できることは勿論である。   Furthermore, in the above embodiment, an example in which the present invention is applied to a box-type vehicle has been described. However, the shape of the vehicle is not particularly limited, and it is needless to say that the present invention can be applied to vehicles having other shapes such as a station wagon. is there.
