Description

本発明は、板厚の異なる板材を突き合せて接合し、この接合した接合部材を車体パネルとして用いるような車両用パネルの補強構造に関するものである。   The present invention relates to a vehicle panel reinforcing structure in which plate members having different thicknesses are butted and joined, and the joined member is used as a vehicle body panel.

従来から、板厚の異なる板材を突き合せて、レーザなどで溶接することにより接合したテーラードブランク材が提供されている。このテーラードブランク材は、用途や設置箇所に応じて板厚や材質等を選択することによって最適なものを配置できると共に、素材形状の自由度が大きいという利点を有している。しかも、テーラードブランク材は、連続的な線溶接によって接合されることから、接合強度が高いなどの長所も有している。
このため、テーラードブランク材は、自動車の車体パネルとして用いられている（例えば、特許文献１参照）。すなわち、自動車の車体パネルのうち、強度の必要な部分の板厚を厚くし、それ程強度の必要でない部分の板厚を薄く形成することによって、自動車の重量を軽くすると共に、材料費を節約するようにしている。 Conventionally, tailored blank materials have been provided in which plate materials having different plate thicknesses are brought into contact with each other and welded with a laser or the like. This tailored blank material has an advantage that an optimum material can be arranged by selecting a plate thickness, a material, and the like according to an application and an installation location, and a degree of freedom of a material shape is large. In addition, tailored blank materials are joined by continuous wire welding, and thus have advantages such as high joining strength.
For this reason, tailored blank materials are used as body panels for automobiles (see, for example, Patent Document 1). That is, by increasing the thickness of the parts that require strength in the body panel of the automobile, and by reducing the thickness of the parts that do not require that much strength, the weight of the automobile is reduced and material costs are saved. I am doing so.

しかしながら、上述した従来のテーラードブランク材においては、板厚の異なる２枚の板材を突き合せて溶接しているので、これら板材の接合部に必ず段差が生じることになり、当該接合部に応力集中が起こるおそれがあった。   However, in the above-described conventional tailored blank material, since two plate materials having different plate thicknesses are butted and welded, a step always occurs at the joint portion of these plate materials, and stress concentration is caused at the joint portion. There was a possibility of happening.

本発明はこのような実状に鑑みてなされたものであって、その目的は、板厚の異なる板材を突き合せて接合するような接合部材の接合部に応力集中が起こらず、当該接合部を補強することが可能な車両用パネルの補強構造を提供することにある。   The present invention has been made in view of such a situation, and the purpose thereof is that stress concentration does not occur in a joint portion of a joining member that joins and joins plate materials having different thicknesses. An object of the present invention is to provide a vehicle panel reinforcing structure that can be reinforced.

上記従来技術の有する課題を解決するために、本発明は、板厚の異なる板材を突き合せて接合し、この接合した接合部材を車体パネルとして用いている車両用パネルの補強構造において、前記接合部材には、接合部と交差する方向へ延在するパネル部材が取付けられている。   In order to solve the above-described problems of the prior art, the present invention provides a vehicle panel reinforcing structure in which plate members having different plate thicknesses are butted and joined, and the joined member is used as a vehicle body panel. A panel member extending in a direction crossing the joint is attached to the member.

また、本発明は、板厚の異なる板材を突き合せて接合し、この接合した接合部材を車体のフロアパネルの一部として用いている車両用パネルの補強構造において、前記接合部材は、接合部を車両前後方向に沿って配置した状態でシート取付部に設けられていると共に、前記接合部材には、前記接合部と交差する方向へ延在するパネル部材が取付けられている。   Further, the present invention provides a vehicle panel reinforcing structure in which plate members having different plate thicknesses are butted and joined, and the joined member is used as a part of a floor panel of a vehicle body. Is provided in the seat attachment portion in a state of being arranged along the vehicle front-rear direction, and a panel member extending in a direction intersecting with the joint portion is attached to the joining member.

しかも、本発明において、前記接合部材は、２箇所以上の接合部を有しており、少なくとも２箇所の接合部に対して前記パネル部材が交差して配置されている。   Moreover, in the present invention, the joining member has two or more joining portions, and the panel member is disposed so as to intersect at least two joining portions.

さらに、本発明において、前記接合部材のうち、シートクッションの車両前方側で、かつ前記接合部が延在する部分には、車両後方から車両前方へ向かって下り傾斜の傾斜面が形成されており、この傾斜面の上下に亘って前記パネル部材が取付けられている。   Further, in the present invention, an inclined surface that is inclined downward from the rear of the vehicle toward the front of the vehicle is formed on the front side of the seat cushion of the joint member and the portion where the joint extends. The panel member is attached to the top and bottom of the inclined surface.

本発明に係る車両用パネルの補強構造では、板厚の異なる板材を突き合せて接合し、この接合した接合部材を車体パネルとして用いているものであって、前記接合部材には、接合部と交差する方向へ延在するパネル部材が取付けられているので、接合部材の接合部に対してパネル部材を横切らせて配置することが可能となる。したがって、本発明の補強構造によれば、接合部材の接合部に集中する応力を軽減させ、当該接合部を補強することができると共に、車体パネルの剛性向上を図ることができる。   In the vehicle panel reinforcing structure according to the present invention, plate members having different plate thicknesses are butted and joined, and the joined joint member is used as a vehicle body panel. Since the panel member extending in the intersecting direction is attached, the panel member can be disposed across the joining portion of the joining member. Therefore, according to the reinforcing structure of the present invention, the stress concentrated on the joint portion of the joint member can be reduced, the joint portion can be reinforced, and the rigidity of the vehicle body panel can be improved.

また、本発明に係る車両用パネルの補強構造では、板厚の異なる板材を突き合せて接合し、この接合した接合部材を車体のフロアパネルの一部として用いているものであって、前記接合部材は、接合部を車両前後方向に沿って配置した状態でシート取付部に設けられていると共に、前記接合部材には、前記接合部と交差する方向へ延在するパネル部材が取付けられているので、シート取付部を補強するのに従前から設けられているパネル部材を接合部材の接合部まで延長し、または当該接合部をシート取付部の下部まで延長することによって、部品点数を増やすことなく、上記した発明の効果を得ることができる。   Further, in the vehicle panel reinforcing structure according to the present invention, plate members having different plate thicknesses are butted and joined, and the joined member is used as a part of the floor panel of the vehicle body. The member is provided in the seat mounting portion in a state where the joint portion is disposed along the vehicle front-rear direction, and a panel member extending in a direction intersecting with the joint portion is attached to the joint member. Therefore, without reinforcing the number of parts by extending the panel member that has been previously provided to reinforce the seat mounting portion to the joint portion of the joining member, or by extending the joint portion to the lower portion of the seat mounting portion. The effects of the above-described invention can be obtained.

さらに、本発明において、前記接合部材は、２箇所以上の接合部を有しており、少なくとも２箇所の接合部に対して前記パネル部材が交差して配置されているので、接合部と接合部との間に位置する板材の板厚を薄くすることができ、より一層自動車の重量軽減と材料コストの低減を図ることができる。   Furthermore, in this invention, since the said joining member has two or more junction parts, and since the said panel member cross | intersects and arrange | positions with respect to at least two junction parts, a junction part and a junction part The thickness of the plate located between the two can be reduced, and the weight of the automobile and the material cost can be further reduced.

また、本発明において、前記接合部材のうち、シートクッションの車両前方側で、かつ前記接合部が延在する部分には、車両後方から車両前方へ向かって下り傾斜の傾斜面が形成されており、この傾斜面の上下に亘って前記パネル部材が取付けられているので、接合部の強度をより高めることができる。   Further, in the present invention, an inclined surface that is inclined downward from the rear of the vehicle toward the front of the vehicle is formed in a portion of the joint member on the vehicle front side of the seat cushion and where the joint extends. And since the said panel member is attached over the upper and lower sides of this inclined surface, the intensity | strength of a junction part can be raised more.

以下、本発明を図示の実施の形態に基づいて詳細に説明する。

FIG. 1 is a perspective view of a floor panel of an automobile to which a vehicle panel reinforcing structure according to an embodiment of the present invention is applied. FIG. 2 is a view before a seat cross member is attached to a front rear floor panel of the floor panel in FIG. FIG. 3 is a cross-sectional view of a tailored blank material serving as a front rear floor panel in FIG. 2, FIG. 4 is a cross-sectional view along line AA in FIG. 2, and FIG. 5 is a cross-sectional view along line BB in FIG. 6 is a cross-sectional view taken along the line CC in FIG. 2, FIG. 7 is a cross-sectional view taken along the line DD in FIG. 2 in a state where the mounting bracket is attached, and FIG. FIG. 9 is a perspective view of the state in which the rear seat is attached to the floor panel as seen from the front of the vehicle.

本実施の形態における自動車の車室内後部側に位置するフロアパネル１は、図１、図２および図９に示す如く、リヤシート１０の前部側が配設される前部リヤフロアパネル（車体パネル）２を備えており、この前部リヤフロアパネル２は、車両前後方向に沿って、ほぼセンタピラー３とタイヤハウスインナパネル４との間に設けられている。
本実施形態の前部リヤフロアパネル２の素材には、板厚の異なる板材を突き合せてレーザ溶接などで接合したテーラードブランク材（接合部材）５が使用されている。このテーラードブランク材５は、図２および図３に示す如く、中央側に板厚の薄いセンタパネル５ａを配置し、左右両側に板厚の厚いサイドパネル５ｂを配置することによって構成されている。板厚は、例えば、センタパネル５ａが０．７ｍｍの板材を用い、サイドパネル５ｂが１．２ｍｍの板材を用いており、これらのパネル５ａ，５ｂを突き合せてレーザ溶接などで接合し、これをプレス加工することにより、所定形状の前部リヤフロアパネル２が形成されることになる。そして、センタパネル５ａおよびサイドパネル５ｂの左右２箇所の接合部Ｗでは、パネルの厚さが変化しているので、当該接合部Ｗは応力集中を受け易い形状となっている。 As shown in FIGS. 1, 2 and 9, the floor panel 1 located on the rear side of the vehicle interior in the present embodiment is a front rear floor panel (vehicle body panel) 2 on which the front side of the rear seat 10 is disposed. The front rear floor panel 2 is provided between the center pillar 3 and the tire house inner panel 4 along the longitudinal direction of the vehicle.
As the material of the front rear floor panel 2 of the present embodiment, a tailored blank material (joining member) 5 in which plate materials having different plate thicknesses are butted and joined by laser welding or the like is used. As shown in FIGS. 2 and 3, the tailored blank material 5 is configured by disposing a center panel 5a having a thin plate thickness on the center side and side panels 5b having a large plate thickness on both the left and right sides. As for the plate thickness, for example, the center panel 5a uses a plate material of 0.7 mm, and the side panel 5b uses a plate material of 1.2 mm. These panels 5a and 5b are butted together and joined by laser welding or the like. The front rear floor panel 2 having a predetermined shape is formed by pressing. And since the thickness of the panel has changed in the joint part W of right and left two places of the center panel 5a and the side panel 5b, the said joint part W becomes a shape which receives a stress concentration easily.

このため、前部リヤフロアパネル２には、図１、図２および図６〜図９に示す如く、左右２箇所の接合部Ｗと交差（クロス）する方向へ延在するシートクロスメンバ（パネル部材）６が取付けられている。すなわち、前部リヤフロパネル２は、接合部Ｗを車両前後方向に沿って配置した状態でシート取付部に設けられており、シート取付部としての役割を有するシートクロスメンバ６が左右２箇所の接合部Ｗに対して交差して配置されている。
前部リヤフロアパネル２のうち、リヤシート１０のシートクッション１０ａの車両前方側で、かつ接合部Ｗが延在する部分には、車両後方から車両前方へ向かって下り傾斜である上方側前向きの傾斜面２ａが車幅方向に沿って形成されており、この傾斜面２ａの上下に亘ってシートクロスメンバ６が左右２箇所の接合部Ｗと交差しながら取付けられている。すなわち、シートクロスメンバ６は、前部リヤフロアパネル２の傾斜面２ａを覆い隠しながら、上縁部６ａおよび下縁部６ｂが左右２箇所の接合部Ｗを橋渡しするようにして前部リヤフロアパネル２に溶接で固定されている。したがって、シートクロスメンバ６は、前部リヤフロアパネル２に形成された左右２箇所の接合部Ｗに集中する応力を軽減し、これら接合部Ｗを補強する役割を果たすことになる。 For this reason, as shown in FIGS. 1, 2 and 6 to 9, the front rear floor panel 2 has a seat cross member (panel member) extending in a direction intersecting (crossing) the two joint portions W on the left and right. ) 6 is attached. That is, the front rear flow panel 2 is provided in the seat mounting portion in a state in which the joint portion W is disposed along the vehicle front-rear direction, and the seat cross member 6 having a role as the seat mounting portion has two joint portions on the left and right sides. It is arranged so as to intersect W.
In the front rear floor panel 2, the front front inclined surface of the seat cushion 10 a of the rear seat 10 and the portion where the joint portion W extends is an upward inclined surface that is inclined downward from the vehicle rear toward the vehicle front. 2a is formed along the vehicle width direction, and the seat cross member 6 is attached so as to intersect the two joint portions W on the left and right sides of the inclined surface 2a. That is, the seat cross member 6 covers the inclined surface 2a of the front rear floor panel 2 while the upper edge portion 6a and the lower edge portion 6b bridge the two joint portions W on the left and right sides. It is fixed by welding. Therefore, the seat cross member 6 serves to relieve the stress concentrated on the two left and right joints W formed on the front rear floor panel 2 and reinforce the joints W.

上記シートクロスメンバ６には、リヤシート１０をフロアパネル１側に取付ける取付金具７が締付け固定されている。そのため、シートクロスメンバ６の車両前方側には、図２および図７〜図９に示す如く、車両後方から車両前方へ向かって下り傾斜面に前側シート取付部８が形成され、シートクロスメンバ６の車両後方側には、車両後方へ向かって屈曲して延びる後側シート取付部９が形成されている。
前側シート取付部８の裏面側には、取付金具７を取付けるための締付ボルト１２と螺合する溶接ナット１４が固着されている。また、後側シート取付部９は、側面視で略三角形状の凸部であって、取付金具７の取付箇所と対応する位置で車両幅方向に所定の間隔を置いて配設されており、車両前方から車両後方へ向かって下り傾斜面には、シートクロスメンバ６の裏面側から車両後方へ向けて斜め上方に突出するスタッドボルト１３が設けられ、スタッドボルト１３の先端にはナット１５が螺合して締付けられるようになっている。なお、後側シート取付部９およびスタッドボルト１３は、１つの取付金具７に対して左右２箇所に用いられるようになっている。 An attachment fitting 7 for attaching the rear seat 10 to the floor panel 1 side is fastened and fixed to the seat cross member 6. Therefore, as shown in FIG. 2 and FIGS. 7 to 9, the front seat mounting portion 8 is formed on the descending inclined surface from the rear of the vehicle toward the front of the vehicle on the front side of the seat cross member 6. A rear seat mounting portion 9 that is bent and extends toward the rear of the vehicle is formed on the rear side of the vehicle.
A welding nut 14 that is screwed with a fastening bolt 12 for attaching the mounting bracket 7 is fixed to the back side of the front seat mounting portion 8. Further, the rear seat mounting portion 9 is a substantially triangular convex portion in a side view, and is disposed at a predetermined interval in the vehicle width direction at a position corresponding to the mounting location of the mounting bracket 7. A stud bolt 13 projecting obliquely upward from the rear surface side of the seat cross member 6 toward the vehicle rear side is provided on the inclined surface descending from the front of the vehicle toward the rear of the vehicle, and a nut 15 is screwed at the tip of the stud bolt 13. It can be tightened together. The rear seat mounting portion 9 and the stud bolt 13 are used at two locations on the left and right with respect to one mounting bracket 7.

上記取付金具７は、図７〜図９に示す如く、車両幅方向に一定の間隔を置いて配置されており、ヒンジ部材（図示せず）に連結され、該ヒンジ部材を介してシートクッション１０ａに取付けられるようになっている。このため、取付金具７は、シートクロスメンバ６と対応して屈曲形成されており、取付金具７の前部締付部７ａは、シートクロスメンバ６の前側シート取付部８に固定され、取付金具７の後部締付部７ｂは、シートクロスメンバ６の後側取付部９に固定されるようになっている。なお、図７は前部リヤフロアパネル２を構成するテーラードブランク材５であって、板厚の薄いセンタパネル５ａに対応する箇所に取付金具７の前部締付部７ａを固定した断面を示し、図８は板厚の厚いサイドパネル５ｂに対応する箇所に取付金具７の後部締付部７ｂを固定した断面を示している。   As shown in FIGS. 7 to 9, the mounting bracket 7 is disposed at a constant interval in the vehicle width direction, is connected to a hinge member (not shown), and the seat cushion 10 a is interposed via the hinge member. It can be mounted on. Therefore, the mounting bracket 7 is bent corresponding to the seat cross member 6, and the front tightening portion 7 a of the mounting bracket 7 is fixed to the front seat mounting portion 8 of the seat cross member 6. 7 is fastened to the rear mounting portion 9 of the seat cross member 6. FIG. 7 is a tailored blank material 5 constituting the front rear floor panel 2, and shows a cross section in which the front tightening portion 7a of the mounting bracket 7 is fixed at a position corresponding to the thin center panel 5a. FIG. 8 shows a cross section in which the rear tightening portion 7b of the mounting bracket 7 is fixed at a position corresponding to the thick side panel 5b.

一方、前部リヤフロアパネル２は、図４〜図６に示す如く、テーラードブランク材５の板厚の厚いサイドパネル５ｂをサイドメンバ２１およびサイドインナパネル２２に接合することによって取付けられている。サイドメンバ２１の内壁面および上端フランジには、リーンフォースメント２３が接合されていると共に、サイドメンバ２１の底部およびサイドインナパネル２２には、トルクボックスパネル２４が接合されている。
すなわち、前部リヤフロアパネル２は、設置部位により、断面略Ｕ字状のサイドメンバ２１に取付けられ、あるいはリーンフォースメント２３を介してサイドメンバ２１およびサイドインナパネル２２に取付けられており、対応するサイドメンバ２１や、サイドメンバ２１、サイドインナパネル２２およびトルクボックスパネル２４と相俟って閉断面構造を形成している。 On the other hand, as shown in FIGS. 4 to 6, the front rear floor panel 2 is attached by joining a thick side panel 5 b of the tailored blank material 5 to a side member 21 and a side inner panel 22. A reinforcement 23 is joined to the inner wall surface and upper end flange of the side member 21, and a torque box panel 24 is joined to the bottom of the side member 21 and the side inner panel 22.
That is, the front rear floor panel 2 is attached to the side member 21 having a substantially U-shaped cross section or is attached to the side member 21 and the side inner panel 22 via the reinforcement 23 depending on the installation site. Together with the side member 21, the side member 21, the side inner panel 22, and the torque box panel 24, a closed cross-sectional structure is formed.

このように、本発明の実施形態の補強構造では、前部リヤフロアパネル２の素材として、板厚の薄いセンタパネル５ａと板厚の厚いサイドパネル５ｂとを突き合せてレーザ溶接などで接合したテーラードブランク材５を使用しても、左右２箇所の接合部Ｗに対してシートクロスメンバ６が交差して配置され、前部リヤフロアパネル２の傾斜面２ａを覆い隠して上縁部６ａおよび下縁部６ｂが接合されているため、シートクロスメンバ６によってテーラードブランク材５の左右２箇所の接合部Ｗを補強することが可能となり、前部リヤフロアパネル２のうち、強度の必要な部分の板厚のみを厚くすることができる。したがって、本発明の実施形態によれば、テーラードブランク材５の使用により自動車を軽量化すると共に、材料費の節約を図ることが可能となり、しかも、前部リヤフロアパネル２として用いることができる。   As described above, in the reinforcing structure of the embodiment of the present invention, as a material of the front rear floor panel 2, a tailored structure in which the thin center panel 5a and the thick side panel 5b are abutted and joined by laser welding or the like. Even if the blank material 5 is used, the seat cross member 6 is arranged so as to intersect the left and right joints W, and covers the inclined surface 2a of the front rear floor panel 2 so as to cover the upper edge 6a and the lower edge. Since the portion 6b is joined, it is possible to reinforce the joint portions W at the left and right portions of the tailored blank member 5 by the seat cross member 6, and the plate thickness of the portion of the front rear floor panel 2 that requires strength. Only can be thickened. Therefore, according to the embodiment of the present invention, it is possible to reduce the weight of the automobile by using the tailored blank material 5 and to save the material cost, and it can be used as the front rear floor panel 2.

以上、本発明の実施の形態につき述べたが、本発明は既述の実施の形態に限定されるものではなく、本発明の技術的思想に基づいて各種の変形および変更が可能である。
例えば、既述の実施形態では、前部リヤフロアパネル２を構成するテーラードブランク材５の接合部Ｗが車両前後方向に沿って配置しているが、本発明の補強構造は、当該接合部Ｗを車幅方向や斜め方向に配置したものにも適用することが可能である。また、本発明の補強構造は、シート取付部となるシートクロスメンバ６に対して適用されているが、テーラードブランク５とリーンフォースメント２３とが重合される部分など、他の部位にも適用することが可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
For example, in the above-described embodiment, the joint portion W of the tailored blank material 5 constituting the front rear floor panel 2 is disposed along the vehicle front-rear direction. The present invention can also be applied to a vehicle disposed in the vehicle width direction or oblique direction.
