特開２００６−１９３００１号公報JP 2006-193001 A

ところで、自動車におけるフロントピラーは、センタピラー等の他の骨格構造体と同様に、自動車の前面衝突時や側面衝突時などの衝突エネルギーを確実に緩和可能にする構造が求められており、かかる要請は最近特に高度化する傾向にある。そこで、フロントピラーは、強度の高い高張力鋼板を使用して構成されている。   By the way, as with other skeleton structures such as a center pillar, a front pillar in an automobile is required to have a structure capable of reliably mitigating collision energy at the time of a frontal collision or a side collision of the automobile. Recently, there is a tendency to become particularly sophisticated. Therefore, the front pillar is configured using a high-strength high strength steel plate.

しかしながら、かかる高張力鋼板で構成されたフロントピラーに一体構成の三角窓支持枠を形成することは、フロントピラー自体の強度が非常に高いが故に、プレス成形を困難にしている。加えて、近来の自動車デザインの多様化要請に答えるべく、三角窓支持枠の形状が意匠的に複雑化してきており、かかる点からも、フロントピラーのプレス成形性をますます困難にしている。そして、三角窓支持枠のデザイン面からフロントピラーの成形性を重視した場合には、強度の比較的低いハイテン材を勢い選択せざるを得なくなってしまう。   However, forming a triangular window support frame integrally formed on such a front pillar made of a high-strength steel plate makes press molding difficult because the strength of the front pillar itself is very high. In addition, in order to respond to the recent diversification of automobile design, the shape of the triangular window support frame has become more complicated in design, which makes the press formability of the front pillar more and more difficult. And, when emphasizing the formability of the front pillar from the design side of the triangular window support frame, it is necessary to momentarily select a high-tensile material having a relatively low strength.

そこで、この発明は、かかる従来の技術における未解決課題に鑑み、三角窓支持枠のデザインの多様化要請に十分答えることができるとともに、フロントピラーの高強度化に対する要請をも果たし得る自動車の三角窓支持枠構造を提供することを目的としている。   Therefore, in view of such unsolved problems in the conventional technology, the present invention can sufficiently satisfy the diversification request for the design of the triangular window support frame, and can also satisfy the demand for increasing the strength of the front pillar. The object is to provide a window support frame structure.

この発明に係る自動車の三角窓支持枠構造は、フロントピラーに三角窓を装着すべくなした自動車の三角窓用窓枠構造であって、フロントピラーに三角窓支持枠設置用開口部を形成し、三角窓支持枠設置用開口部に、別体構成の三角窓支持枠を装着設置して、三角窓支持枠が三角窓を支承するように構成したことを特徴とする。   The triangular window support frame structure for an automobile according to the present invention is a window frame structure for an automobile triangular window in which a triangular window is to be mounted on a front pillar, and an opening for installing a triangular window support frame is formed in the front pillar. The triangular window support frame is mounted and installed in the triangular window support frame installation opening so that the triangular window support frame supports the triangular window.

このように構成する上記発明は、フロントピラーに対して三角窓を支承する三角窓支持枠を別体構成にしたことにより、三角窓支持枠自体のデザイン性、例えば三角窓支持枠における車室側奥行きを厚く形成する等のデザインの選択自由度を広げて、デザインの多様化要請に十分答えることができる。   In the above-described invention, the triangular window support frame that supports the triangular window with respect to the front pillar is configured as a separate structure, so that the design of the triangular window support frame itself, for example, the passenger compartment side of the triangular window support frame It is possible to expand the degree of freedom of design choices, such as forming a deep depth, and to fully respond to the diversification of design.

しかも、上記発明に係るフロントピラーは、三角窓支持枠を別体構成にしたことにより、三角窓支持枠のプレス成形性を考慮しなくてもデザインすることができることになって、強度の非常に高い高張力鋼板で構成することができ、自動車の衝突事故等に遭遇した際の衝撃エネルギーを効率よく緩和して、自動車の安全走行性能を益々向上させることができる。   Moreover, the front pillar according to the above invention can be designed without considering the press formability of the triangular window support frame by making the triangular window support frame a separate structure, and has a very strong strength. It can be made of a high-tensile steel plate, and can effectively reduce the impact energy when encountering an automobile collision accident and the like, thereby further improving the safe driving performance of the automobile.

本発明者の試作実験の結果によれば、三角窓支持枠自体は、別体構成ゆえに例えば５９０Ｍｐａ級の高張力鋼板を使用して、プレス成形性を高めることができる一方、三角窓支持枠を別体構成としたフロントピラーは、４４０Ｍｐａ級の高張力鋼板を使用して高強度化構成にしたとしても、そのプレス成形性に問題を起こすことがなかった。   According to the results of the inventor's prototype experiment, the triangular window support frame itself can be improved in press formability by using, for example, a high-tensile steel plate of 590 Mpa class because of the separate structure. Even if the front pillar having a separate structure is made to have a high-strength structure using a 440 Mpa-class high-tensile steel plate, there was no problem in its press formability.

この発明の実施例における自動車の三角窓支持枠構造は、三角窓支持枠のデザイン性の自由度確保の要請に十分答えることができるとともに、フロントピラーの高強度化をも果たし得るように構成している。以下、図１〜図４を用いて、この発明を採用した実施例に係る自動車の三角窓支持枠構造について説明する。   The triangular window support frame structure of an automobile according to an embodiment of the present invention is configured so that it can sufficiently meet the demand for ensuring the degree of freedom in design of the triangular window support frame and can also increase the strength of the front pillar. ing. Hereinafter, a triangular window support frame structure for an automobile according to an embodiment adopting the present invention will be described with reference to FIGS.

図１に示すように、フロントピラー１は、ウインドガラス２の側部に沿うように設置されて、自動車の車体３の前部骨格の一部を構成しており、図４に示すように、車体３の外側に位置するフロントピラーアウタ１１と車体３の内側(車室側)に位置するフロントピラーインナ１２とを、その各端末フランジ部同士を互いに接合することにより閉断面形状の骨格部材として構成している。   As shown in FIG. 1, the front pillar 1 is installed along the side of the window glass 2 and constitutes a part of the front skeleton of the vehicle body 3 of the automobile. A front pillar outer 11 positioned outside the vehicle body 3 and a front pillar inner 12 positioned inside (vehicle compartment side) of the vehicle body 3 are joined to each other as a skeleton member having a closed cross-sectional shape by joining their terminal flange portions to each other. It is composed.

そして、フロントピラーインナ１２には、図３及び図４に示すように、ドアー４の前側部に沿うような位置において、三角窓支持枠設置用開口部１２ａが形成されているとともに、三角窓支持枠設置用開口部１２ａを取り囲むように三角窓支持枠設置部１２ｂが、車外側に膨出するように形成されている。三角窓支持枠設置部１２ｂには、図３において明らかなように、フロントピラー１に対して別体構成の三角窓支持枠５が設置されている。   As shown in FIGS. 3 and 4, the front pillar inner 12 has a triangular window support frame installation opening 12 a formed at a position along the front side of the door 4, and a triangular window support. A triangular window support frame installation part 12b is formed so as to bulge out of the vehicle so as to surround the frame installation opening 12a. As is apparent from FIG. 3, the triangular window support frame installation portion 12 b is provided with a triangular window support frame 5 having a separate structure with respect to the front pillar 1.

三角窓支持枠５は、中央部に開口部５ａを有する略椀型を呈して構成されている。開口部５ａを囲繞する立壁状の側壁部５ｂは、若干の傾斜面を呈しているとともに、縦方向に延在する複数個の補強ビード部５ｃが互いに離間した状態で形成されている。側壁部５ｂにおける各補強ビード部５ｃの間には、スポット溶接等の溶接を施すための支持枠側溶接面部５ｄが形成されている。支持枠側溶接面部５ｄに関連して、フロントピラーインナ１２の三角窓支持枠設置部１２ｂは、やはり若干の傾斜面を呈する起立壁形状に形成されている。   The triangular window support frame 5 has a substantially bowl shape having an opening 5a at the center. The standing wall-shaped side wall 5b surrounding the opening 5a has a slightly inclined surface, and a plurality of reinforcing bead portions 5c extending in the vertical direction are formed in a state of being separated from each other. Between each reinforcing bead part 5c in the side wall part 5b, the support frame side welding surface part 5d for performing welding, such as spot welding, is formed. In relation to the support frame side welded surface portion 5d, the triangular window support frame installation portion 12b of the front pillar inner 12 is formed in an upright wall shape that also exhibits a slight inclined surface.

そして、別体構成の三角窓支持枠５をフロントピラーインナ１２に装着設置するには、先ず、三角窓支持枠５側の支持枠側溶接面部５ｄとフロントピラーインナ１２側の三角窓支持枠設置部１２ｂとを順次互いに当接した状態で重合しておく。次に、図２に示すように、支持枠側溶接面部５ｄと三角窓支持枠設置部１２ｂとは、共にスポット溶接等により溶接して、図２に示すように、複数個所に溶接部６を形成することによって接合することになる。更に、三角窓支持枠４は、その取付けフランジ部５ｅを、図４に示すように、補強部材７及びフロントピラーアウタ１１の開口フランジ７ａ、１１ａに順次重合させた状態において、フロントピラーアウタ１１の開口フランジ１１ａの車外側に接着剤８を塗布することにより、三角窓９を接着設置されている。かかる状態において、三角窓９は、三角窓支持枠５によって支承されることになる。   In order to mount and install the triangular window support frame 5 of the separate structure on the front pillar inner 12, first, the support frame side welded surface portion 5d on the triangular window support frame 5 side and the triangular window support frame on the front pillar inner 12 side are installed. The portions 12b are sequentially superposed in contact with each other. Next, as shown in FIG. 2, the support frame side welding surface portion 5d and the triangular window support frame installation portion 12b are both welded by spot welding or the like, and as shown in FIG. It joins by forming. Further, the triangular window support frame 4 has its mounting flange portion 5e, as shown in FIG. The triangular window 9 is bonded and installed by applying the adhesive 8 to the outside of the opening flange 11a. In such a state, the triangular window 9 is supported by the triangular window support frame 5.

上記のように構成する本発明に係る実施例は、フロントピラー１に対して三角窓９を支承する三角窓支持枠５を別体構成にしたことにより、比較的深絞りを可能とするプレス成形性のよいパネル材を使用することができることから、三角窓支持枠５自体のデザイン性、例えば三角窓支持枠５における車室側奥行き(図１４の符号「Ｗ」を参照)を厚く形成する等のデザインの選択自由度を広げるとともに、車室の拡大にも繋げることができる。   In the embodiment according to the present invention configured as described above, the triangular window support frame 5 that supports the triangular window 9 with respect to the front pillar 1 is formed as a separate body, so that press forming that enables relatively deep drawing is possible. Since a panel material with good properties can be used, the design of the triangular window support frame 5 itself, for example, the vehicle interior side depth (see reference sign “W” in FIG. 14) of the triangular window support frame 5 is formed thick. As well as expanding the degree of freedom in choosing the design of the car, it can also lead to the expansion of the cabin.

しかも、上記発明に係るフロントピラー１は、三角窓支持枠５を別体構成にしたことにより、三角窓支持枠５のプレス成形性を考慮しなくてもデザインすることができることになって、剛性の非常に高い高張力鋼板で構成することができ、自動車の衝突事項等に遭遇した際の衝撃エネルギーを効率よく緩和して、自動車の安全走行性能を益々向上させることができる。   Moreover, the front pillar 1 according to the above invention can be designed without considering the press formability of the triangular window support frame 5 by adopting a separate structure for the triangular window support frame 5, and thus having rigidity. The high-strength steel sheet can be made of a high strength steel, and the impact energy when encountering a collision of an automobile can be efficiently reduced, thereby improving the safe driving performance of the automobile.

本発明者の試作実験の結果によれば、三角窓支持枠５自体は、例えば５９０Ｍｐａ級の高張力鋼板を使用したとしても、プレス成形性を高めることができる一方、三角窓支持枠５を別体構成としたフロントピラー１は、４４０Ｍｐａ級の高張力鋼板を使用して高強度化構成にしたとしても、そのプレス成形性に問題を起こすことがなかった。   According to the results of the inventor's prototype experiment, the triangular window support frame 5 itself can improve press formability even when, for example, a 590 MPa high-strength steel plate is used. Even if the front pillar 1 having a body structure is made to have a high strength structure using a high strength steel plate of 440 Mpa class, there was no problem in its press formability.

以上説明したこの発明は、三角窓支持枠のデザイン性の自由度確保の要請に十分答えることができるとともに、フロントピラーの高強度化をも果たし得る自動車の三角窓支持枠構造を提供することができるため、自動車のフロントピラーに三角窓を設置するための三角窓支持枠構造等に好適であるといえる。   The present invention described above can provide a triangular window support frame structure for an automobile that can sufficiently meet the demand for ensuring the degree of freedom in design of the triangular window support frame and can also increase the strength of the front pillar. Therefore, it can be said to be suitable for a triangular window support frame structure for installing a triangular window on the front pillar of an automobile.
