Description

本発明は、前ガラスやルーフを支持している車両のフロントピラーに関するものである。   The present invention relates to a front pillar of a vehicle that supports a front glass and a roof.

フロントピラーには、管状の中空部材を用いることで、死角範囲を狭め、そして、中空部材の上部にルーフパネルをスポット溶接しているものがある（例えば、特許文献１参照。）。
特開２００６−１８２０７９号公報（第６頁、図３−図４） Some front pillars use a tubular hollow member to narrow the blind spot range, and a roof panel is spot-welded to the top of the hollow member (see, for example, Patent Document 1).
JP 2006-182079 A (page 6, FIGS. 3 to 4)

しかし、特許文献１の車両のフロントピラー構造では、中空部材にルーフパネルの端部をスポット溶接するには、重ね合わせた溶接箇所を電極で直接挟むことができないため、片側の電極で加圧するスポット溶接を用いる必要があり、専用のスポット溶接設備が必要になるとともに、スポット溶接装置が大きくなるという問題がある。   However, in the front pillar structure of the vehicle of Patent Document 1, in order to spot weld the end of the roof panel to the hollow member, the overlapped welded portion cannot be directly sandwiched between the electrodes, so the spot pressed with the electrode on one side There is a problem that it is necessary to use welding, a dedicated spot welding facility is required, and a spot welding apparatus becomes large.

本発明は、中空部材を採用しても、スポット溶接装置の小型化を維持することができ、スポット溶接が容易で、従来用いられているフランジを重ねて挟み込み通電するスポット溶接を使用することができる車両のフロントピラーを提供することを課題とする。   Even if a hollow member is used, the present invention can maintain the downsizing of the spot welding apparatus, is easy to spot weld, and can use a conventionally used spot welding in which a flange is overlapped and energized. It is an object of the present invention to provide a vehicle front pillar.

請求項１に係る発明は、車両のルーフに連なり前ガラスを支持し、車両の外側へ向けたアウタパネルと、車室に向けたインナパネルと、を備えた車両のフロントピラーにおいて、アウタパネルとインナパネルとの間に設けた中空部材と、中空部材よりルーフに張り出して接合しているアウタパネルの端をなすルーフ接合アウタフランジ部と、ルーフ接合アウタフランジ部に重ねて接合し且つ、中空部材から延長されたルーフ接合延長フランジ部と、を備えていることを特徴とする。   According to a first aspect of the present invention, there is provided a vehicle front pillar including an outer panel directed to the outside of a vehicle and an inner panel directed to a passenger compartment, which is connected to a roof of the vehicle, supports the front glass, and the outer panel and the inner panel. Between the hollow member, a roof joint outer flange portion that forms an end of the outer panel that projects from the hollow member to the roof, and is joined to and overlapped with the roof joint outer flange portion. And a roof joint extension flange portion.

請求項２に係る発明は、インナパネルは、ルーフ接合延長フランジ部に隣接して、アウタパネルの上部に連なるルーフを接合するルーフ接合インナ外側フランジ部を備えていることを特徴とする。   The invention according to claim 2 is characterized in that the inner panel includes a roof joint inner outer flange portion that joins a roof continuous with an upper portion of the outer panel adjacent to the roof joint extension flange portion.

請求項１に係る発明では、フロントピラーは、アウタパネルとインナパネルとの間に設けた中空部材と、中空部材よりルーフに張り出して接合しているアウタパネルの端をなすルーフ接合アウタフランジ部と、ルーフ接合アウタフランジ部に重ねて接合し且つ、中空部材から延長されたルーフ接合延長フランジ部と、を備えているので、フロントピラーは中空部材を採用しても、スポット溶接用の設備は従来とほぼ同様の仕様となり、スポット溶接装置の小型化を維持することができる。   In the invention according to claim 1, the front pillar includes a hollow member provided between the outer panel and the inner panel, a roof joining outer flange portion that forms an end of the outer panel that projects from the hollow member to the roof, and a roof. And a roof joint extension flange portion that is joined to the joint outer flange portion and extended from the hollow member, so even if the front pillar employs a hollow member, the spot welding equipment is almost the same as the conventional one. It becomes the same specification, and the size reduction of a spot welding apparatus can be maintained.

また、中空部材を採用しても、スポット溶接の溶接条件は従来とほぼ同様となり、スポット溶接は容易になる。
すなわち、中空部材にはフランジが無く、一般的なスポット溶接、例えば、フランジ同士を重ねて挟んで加圧し、通電するという溶接作業は困難であるが、フランジの無い範囲を最小限にすることで、スポット溶接は容易になる。 Moreover, even if a hollow member is employed, the welding conditions for spot welding are substantially the same as in the prior art, and spot welding becomes easy.
In other words, the hollow member does not have a flange, and general spot welding, for example, a welding operation in which the flanges are overlapped with each other and pressurized and energized is difficult, but by minimizing the range without the flange. Spot welding becomes easy.

請求項２に係る発明では、インナパネルは、ルーフ接合延長フランジ部に隣接して、アウタパネルの上部に連なるルーフを接合するルーフ接合インナ外側フランジ部を備えているので、中空部材を採用しても、インナパネルとアウタパネルの接合に際し、従来用いられているフランジを重ねて挟み込み通電するスポット溶接を使用することができる。   In the invention according to claim 2, the inner panel includes a roof joint inner outer flange portion that joins the roof continuous with the upper portion of the outer panel adjacent to the roof joint extension flange portion. When joining the inner panel and the outer panel, it is possible to use spot welding in which a conventional flange is overlapped and energized.

インナパネル（ピラーインナパネル１８）では、中空部材５３の第３側部６３へピラーインナ内部６７に形成されたピラーインナパネル内縁開先９３が、所定の複数のピッチＰ１で形成されて重ねられ、溶接（例えばミグ溶接）されることで得られた第１溶接金属部９２で接合されている。Ｌｗは第１溶接金属部９２の溶接長である。Ｐ１は一定ではない。   In the inner panel (pillar inner panel 18), the pillar inner panel inner edge groove 93 formed in the pillar inner interior 67 is formed on the third side portion 63 of the hollow member 53 and overlapped with a predetermined plurality of pitches P1. It joins with the 1st weld metal part 92 obtained by (for example, MIG welding). Lw is the weld length of the first weld metal portion 92. P1 is not constant.

さらに、インナパネル（ピラーインナパネル１８）では、中空部材５３の第１側部６１にインナパネル（ピラーインナパネル１８）のピラーインナパネル中央部６６に貫通形成されたピラーインナパネル穴開先９４が、所定の複数のピッチＰ２で開けられて重ねられ、溶接（例えばミグ溶接）されることで得られた第２溶接金属部９２ａで接合されている。Ｐ２は一定ではない。   Further, in the inner panel (pillar inner panel 18), a pillar inner panel hole 94 is formed in the first side 61 of the hollow member 53 so as to penetrate the pillar inner panel central portion 66 of the inner panel (pillar inner panel 18). The second weld metal portions 92a obtained by being opened and overlapped with a plurality of predetermined pitches P2 and being welded (for example, MIG welding) are joined. P2 is not constant.

次に、本発明の車両のフロントピラーの作用を説明する。
図６に示しているフロントピラー１１では、ルーフ１６に接合している上部２４は、中空部材５３の第４側部６４に、第４側部６４の延長に相当するルーフ接合延長フランジ部５５を接合したので、中空部材５３を用いても、一般的なスポット溶接の電極、例えば、第１電極チップ１０１及び第２電極チップ１０２とでルーフ接合延長フランジ部５５を矢印ａ３、矢印ａ４のように直接挟んで加圧することができる。その結果、延長したルーフ接合延長フランジ部５５にアウタパネル（ピラーアウタパネル１７）のルーフ接合アウタフランジ部５４並びにルーフ１６のルーフスキンフランジ部８７を重ね合わせて、一般的なスポット溶接の電極で直接３枚を挟んで加圧し、スポット溶接を施すことができる。従って、フロントピラー１１では、中空部材５３を採用しても、スポット溶接用の設備は従来とほぼ同様の仕様となり、スポット溶接装置の小型化を維持することができる。 Next, the operation of the front pillar of the vehicle of the present invention will be described.
In the front pillar 11 shown in FIG. 6, the upper portion 24 joined to the roof 16 has a roof joining extension flange portion 55 corresponding to the extension of the fourth side portion 64 on the fourth side portion 64 of the hollow member 53. Even if the hollow member 53 is used, the roof joint extension flange 55 is connected to the general spot welding electrode, for example, the first electrode tip 101 and the second electrode tip 102 as indicated by arrows a3 and a4. It can be directly pinched and pressurized. As a result, the roof joint outer flange portion 54 of the outer panel (pillar outer panel 17) and the roof skin flange portion 87 of the roof 16 are overlapped with the extended roof joint extension flange portion 55, and three sheets are directly formed by general spot welding electrodes. It is possible to perform spot welding by pressurizing the sheet. Therefore, in the front pillar 11, even if the hollow member 53 is employed, the spot welding equipment has substantially the same specifications as the conventional one, and the spot welding apparatus can be kept downsized.

また、フロントピラー１１では、中空部材５３を用いても、一般的なスポット溶接の電極で直接３枚を挟んで加圧し、スポット溶接を施すことができ、結果的に、中空部材５３を採用しても、スポット溶接の溶接条件は従来とほぼ同様となり、スポット溶接は容易になる。   Further, in the front pillar 11, even if the hollow member 53 is used, it is possible to perform spot welding by directly sandwiching and pressing three sheets with a general spot welding electrode. As a result, the hollow member 53 is employed. However, the welding conditions for spot welding are almost the same as in the prior art, and spot welding becomes easy.

さらに、フロントピラー１１では、中空部材５３を用いても、インナパネル（ルーフ１６に位置するルーフサイドレールインナパネル７４）のインナ外側フランジ部６８とアウタパネル（ルーフサイドレールアウタパネル７７）のアウタ外側フランジ部８２の接合に際し、従来のスポット溶接の電極、例えば、第３電極チップ１０３及び第４電極チップ１０４とで矢印ａ４、矢印ａ５のように直接挟んで加圧することができる。従って、従来用いられているフランジを重ねて挟み込み通電するスポット溶接を使用することができる。   Further, in the front pillar 11, even when the hollow member 53 is used, the inner outer flange portion 68 of the inner panel (the roof side rail inner panel 74 located on the roof 16) and the outer outer flange portion of the outer panel (the roof side rail outer panel 77). When joining 82, it is possible to apply pressure by directly sandwiching between electrodes of conventional spot welding, for example, the third electrode tip 103 and the fourth electrode tip 104 as indicated by arrows a4 and a5. Therefore, it is possible to use spot welding in which a conventionally used flange is overlapped and energized.

図５、図６、図１０に示しているフロントピラー１１では、中空部材５３にピラーインナパネル１８を溶接するために、ピラーインナパネル１８にピラーインナパネル内縁開先９３を形成したので、スポット溶接に比べ、フロントピラー１１に加わる荷重をピラーインナパネル１８に伝えることができ、フロントピラー１１の強度を高めることができる。   In the front pillar 11 shown in FIGS. 5, 6, and 10, the pillar inner panel inner edge groove 93 is formed on the pillar inner panel 18 in order to weld the pillar inner panel 18 to the hollow member 53. In comparison with this, the load applied to the front pillar 11 can be transmitted to the pillar inner panel 18, and the strength of the front pillar 11 can be increased.

図１０に示しているフロントピラー１１では、中空部材５３にピラーインナパネル１８を溶接するために、ピラーインナパネル１８にピラーインナパネル穴開先９４を貫通形成しているので、スポット溶接に比べ、フロントピラー１１に加わる荷重をピラーインナパネル１８により確実に伝えることができ、フロントピラー１１の強度をより高めることができる。   In the front pillar 11 shown in FIG. 10, in order to weld the pillar inner panel 18 to the hollow member 53, the pillar inner panel 18 has a pillar inner panel hole groove 94 formed therethrough. The load applied to the front pillar 11 can be reliably transmitted by the pillar inner panel 18, and the strength of the front pillar 11 can be further increased.
