Description

本発明は、例えばバックドアなどのアウタパネル及びインナパネルからなる閉断面状の開閉部材を備えた車両構造に関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle structure, such as a back door, provided with an opening/closing member having a closed cross-section consisting of an outer panel and an inner panel.

一般に、車両のバックドアは、アウタパネル及びインナパネルの外縁部を結合した構造とされ、そのインナパネルに形成したロック取付け座に補強部材が配設されると共に、両パネル間に挿入したワックスノズルにより、両パネルの結合部にワックス（シーラー）が塗布されている（例えば特許文献１）。 In general, the back door of a vehicle has a structure in which the outer edge of an outer panel and an inner panel are joined together. , wax (sealer) is applied to the joining portion of both panels (for example, Patent Document 1).

特開２０１０－１４３５３６号公報（請求項１、段落００１４、００１８、図４）JP 2010-143536 A (claim 1, paragraphs 0014, 0018, FIG. 4)

ところで、車両のバックドアには、そのアウタパネルにキャラクタラインが形成され、このキャラクタラインが、アウタパネルの振動や変形を誘発するおそれのある剛性断点を構成することがある。 By the way, a character line is formed on the outer panel of the back door of a vehicle, and the character line may constitute a rigid breaking point that may induce vibration or deformation of the outer panel.

これに対し、インナパネルに設定したロック部材の取付部位を補強する補強部材を利用することにより、専用の補強部材を用いることなく、アウタパネルのキャラクタラインの周辺を補強することが考えられる。 On the other hand, it is conceivable to reinforce the periphery of the character line of the outer panel by using a reinforcing member that reinforces the mounting portion of the lock member set in the inner panel without using a dedicated reinforcing member.

ただ、ロック部材の取付部位からキャラクタラインの周辺まで補強部材を延設することにより、その延設部位がインナパネルとアウタパネルとの間に跨ることになり、両パネル間でのシーラー塗布の邪魔になったり、その塗布装置を損傷させたりするおそれがある。 However, by extending the reinforcing member from the mounting portion of the lock member to the periphery of the character line, the extended portion straddles between the inner panel and the outer panel, which interferes with the sealer application between the two panels. or damage the applicator.

本発明は、キャラクタライン周辺を効果的に補強しつつ、インナパネル及びアウタパネル間で容易にシーラー塗布することのできる車両構造の提供を目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle structure that can effectively reinforce the periphery of a character line and easily apply a sealer between an inner panel and an outer panel.

上記目的を達成するために、本発明に係る車両構造は、アウタパネル及びインナパネルからなる閉断面状の開閉部材を備え、そのインナパネルに、開閉部材をロックするロック部材を取り付けると共に、このロック部材を取り付ける部位を補強する補強部材を設けたものであり、アウタパネルに一方向に延びる剛性断点を形成し、補強部材に先端部を剛性断点又はその近傍に接合して補強する脚部を突設し、この脚部の側縁部にロック部材の取付部位に対向するインナパネルの作業用開口に向かって突出するフランジを形成したものである。 In order to achieve the above object, a vehicle structure according to the present invention includes an opening/closing member having a closed cross-section consisting of an outer panel and an inner panel. A rigid break point extending in one direction is formed in the outer panel, and the tip of the reinforcing member is joined to the rigid break point or its vicinity to protrude the reinforcing leg. A flange projecting toward the working opening of the inner panel opposite to the mounting portion of the lock member is formed on the side edge of the leg.

以上のとおり、本発明によると、バックドアなどの開閉部材を構成するアウタパネル及びインナパネルのうち、アウタパネルに、キャラクタラインなどの剛性断点を形成すると共に、インナパネルに、ロック部材の取付部位を補強する補強部材を設け、その補強部材から突出する脚部を剛性断点又はその近傍に接合するようにしている。 As described above, according to the present invention, of the outer panel and the inner panel that constitute an opening/closing member such as a back door, the outer panel is provided with a rigid breaking point such as a character line, and the inner panel is provided with a mounting portion for a locking member. A reinforcing member is provided for reinforcement, and the leg protruding from the reinforcing member is joined at or near the rigid breaking point.

これにより、インナパネルからアウタパネルまで掛け渡すように延設した補強部材の脚部で、キャラクタラインなどの剛性断点及びその周辺を補強することができ、専用の補強部材を用いることなく、車両走行時に、剛性断点に起因するアウタパネルの振動が生じたり、開閉部材を開閉する際に、剛性断点に起因するアウタパネルの変形が生じたりするのを防止することができる。 As a result, the legs of the reinforcing member extending from the inner panel to the outer panel can reinforce the rigidity breaking point such as the character line and its surroundings. Occasionally, it is possible to prevent the outer panel from vibrating due to the rigid breaking point, and from deforming the outer panel due to the rigid breaking point when opening and closing the opening/closing member.

また、脚部の側縁部にフランジを形成して作業用開口に向けて突出させるので、シーラー塗布装置を作業用開口からアウタパネル及びインナパネル間に挿入してシーラー塗布する際、そのシーラー塗布装置が両パネル間に掛け渡した脚部の側縁部のエッジに接触して損傷するのを防止することができ、さらに、シーラー塗布装置を脚部に接触させてシーラー塗布部までガイドすることができる。しかも、脚部にフランジを形成することにより、両パネル間に掛け渡した脚部の剛性を高めることができ、剛性断点及びその周辺を確実に補強することができる。 In addition, since the flanges are formed on the side edges of the legs and protrude toward the working opening, when the sealer applying device is inserted between the outer panel and the inner panel from the working opening to apply the sealer, the sealer applying device can be prevented from contacting and damaging the edge of the side edge of the leg spanned between both panels, and furthermore, the sealer applicator can be brought into contact with the leg and guided to the sealer application part. can. Moreover, by forming the flanges on the legs, the rigidity of the legs spanned between both panels can be increased, and the rigidity breaking point and its periphery can be reliably reinforced.

The leg 9 is joined near the character line 6 to reinforce the outer panel 1, and flanges 10 and 11 are formed on the side edges of the leg 9. As shown in FIG.

アウタパネル１は、バックドア５の外面を構成する金属製の板部材であり、このアウタパネル１にライン状の凹凸を形成することにより、バックドア５の外面にキャラクタライン６が構成される。キャラクタライン６は、車両のデザインを向上させる一方、アウタパネル１の振動や変形を誘発するおそれのある剛性断点を構成する。 The outer panel 1 is a metal plate member forming the outer surface of the back door 5 , and character lines 6 are formed on the outer surface of the back door 5 by forming line-shaped unevenness on the outer panel 1 . The character line 6 improves the design of the vehicle, but constitutes a rigid breaking point that may induce vibration and deformation of the outer panel 1 .

インナパネル２は、バックドア５の内面側を構成する金属製の板部材であり、その外縁部を外面側に突出させてアウタパネル１との結合部３を形成することにより、両パネル１、２間に空間を形成しつつバックドア５が構成される。インナパネル２の外縁部には、外面側に突出することによって段部１２が形成され、段部１２の下部の車幅方向中央が補強部材７で補強されて、バックドア５を閉状態に維持するためのロック部材８が両パネル１、２間の空間内に取り付けられる。 The inner panel 2 is a metal plate member forming the inner surface side of the back door 5, and the outer edge portion of the inner panel 2 protrudes outward to form a joint portion 3 to be connected to the outer panel 1. A back door 5 is constructed while forming a space therebetween. A stepped portion 12 is formed on the outer edge of the inner panel 2 by protruding outward, and the center of the lower portion of the stepped portion 12 in the vehicle width direction is reinforced with a reinforcing member 7 to keep the back door 5 closed. A locking member 8 for locking is mounted in the space between both panels 1,2.

インナパネル２には、両パネル１、２間の空間内で作業するための作業用開口１３がロック部材８の取付部位に対向するように形成され、この作業用開口１３を通じて、インナパネル２の内面側からロック部材８を取り付けたり、結合部３にシーラー４を塗布したりするようになっている。 The inner panel 2 is formed with a working opening 13 for working in the space between the panels 1 and 2 so as to face the mounting portion of the lock member 8. Through this working opening 13, the inner panel 2 can be A lock member 8 is attached from the inner surface side, and a sealer 4 is applied to the coupling portion 3. - 特許庁

補強部材７は、例えば、段部１２及びその両側のコーナー部に沿う形状の金属板とされて、その中央にロック部材８を下方に貫通させる貫通穴１４が形成され、幅方向両側から一対の脚部９が両パネル１、２間に架け渡されるように突出している。 The reinforcing member 7 is, for example, a metal plate having a shape along the stepped portion 12 and the corner portions on both sides thereof. A leg 9 protrudes so as to span between the panels 1 and 2. - 特許庁

脚部９は、その先端をマスチックなどによる接着層１５を介して、アウタパネル１の内面のうちのキャラクタライン６の近傍に接着され、キャラクタライン６によって誘発されるアウタパネル１の振動や変形を防止する。このように、ロック部材８の取付部位を補強する補強部材７により、専用の補強部材を用いることなく、アウタパネル１のキャラクタライン６の周辺が補強される。 The ends of the legs 9 are adhered to the vicinity of the character lines 6 on the inner surface of the outer panel 1 via an adhesive layer 15 made of mastic or the like to prevent vibration and deformation of the outer panel 1 induced by the character lines 6. . In this way, the periphery of the character line 6 of the outer panel 1 is reinforced by the reinforcing member 7 that reinforces the mounting portion of the locking member 8 without using a dedicated reinforcing member.

一対の脚部９の側縁部に形成されるフランジ１０、１１のうち、内側縁部のフランジ１０は、斜め上方に突出するよう形成されて、インナパネル２の作業用開口１３に向かって突出し、外側縁部のフランジ１１は、斜め下方に突出するよう形成されて、アウタパネル１に向かって突出している。フランジ１０、１１によって脚部９の剛性が高められ、アウタパネル１がより効果的に補強される。 Of the flanges 10 and 11 formed on the side edges of the pair of legs 9, the flange 10 on the inner edge is formed to protrude obliquely upward toward the working opening 13 of the inner panel 2. , the flange 11 of the outer edge is formed to protrude obliquely downward and protrudes toward the outer panel 1 . The rigidity of the leg portion 9 is increased by the flanges 10, 11, and the outer panel 1 is reinforced more effectively.

図４及び図５に示すように、インナパネル２の内面側から作業用開口１３にシーラー塗布装置１６を挿入して、結合部３にシーラー４を塗布するには、適宜、脚部９の内側縁部のフランジ１０によってシーラー塗布装置１６を結合部３までガイドするようにする。 As shown in FIGS. 4 and 5, in order to insert the sealer applicator 16 into the work opening 13 from the inner surface side of the inner panel 2 and apply the sealer 4 to the connecting portion 3, the inside of the leg portion 9 is properly An edge flange 10 guides a sealer applicator 16 to the joint 3 .

脚部９の内側縁部のフランジ１０をインナパネル２の作業用開口１３に向けて突出させているので、両パネル１、２間に架け渡された脚部９で、シーラー塗布装置１６をガイドする際に、あるいは結合部３にシーラー４を塗布する際に不意に、脚部９の側縁部のエッジがシーラー塗布装置１６に接触するのを阻止することができ、シーラー塗布装置１６の破損を防止することができる。 Since the flange 10 on the inner edge of the leg 9 protrudes toward the working opening 13 of the inner panel 2, the leg 9 spanned between the panels 1 and 2 guides the sealer applicator 16. When applying the sealer 4 to the joint 3, the edge of the side edge of the leg 9 can be prevented from unexpectedly contacting the sealer application device 16, and the sealer application device 16 can be damaged. can be prevented.
