Description

本発明は、自動車のフロントピラー基部周辺構造に関し、さらに詳しくは、ダッシュサイドパネルの上縁部とピラーパネルとの結合構造に係わるものである。 The present invention relates to a structure around a front pillar base portion of an automobile, and more particularly, to a connection structure between an upper edge portion of a dash side panel and a pillar panel.

自動車の車室前部はダッシュパネルによってエンジン室と区画され、ダッシュパネルの左右両側には、車体側壁の室内側の面を構成するダッシュサイドパネルが接合され、さらに、左右のダッシュサイドパネルの室外側にはヒンジリンフォースを挟んでピラーパネル（サイドボディアウターパネル）の下部が接合されている。ピラーパネルの上部すなわちピラー部は、ダッシュサイドパネルの上縁部を越えて上方に延び、ルーフサイドに達している（例えば特許文献１参照）。 The front part of the vehicle compartment is separated from the engine compartment by a dash panel. Dash side panels constituting the interior side of the vehicle body side wall are joined to the left and right sides of the dash panel. The lower part of the pillar panel (side body outer panel) is joined to the outside with the hinge reinforcement interposed therebetween. The upper part of the pillar panel, that is, the pillar part, extends upward beyond the upper edge part of the dash side panel and reaches the roof side (see, for example, Patent Document 1).

上記ダッシュサイドパネルの上縁部とピラーパネルとの結合部分は、運転席および助手席の直ぐ前方に位置するので、自動車のＮＶＨ性能、特に、静粛性（騒音レベル低減）において重要な部分でもある。従来、このダッシュサイドパネルの上縁部とピラーパネルとの結合部分では、比較のために作成した図７に示されるように、ダッシュサイドパネル７２の上縁部７２１，７２２，７２３の形状をピラーパネル７３のピラー部７３１，７３２および窓開口フランジ部７３３に追従させるか、図８に示されるように、ダッシュサイドパネル８２の上縁部８２３にピラーパネル８３の下部８３４の形状を追従させることで部材間の隙間を無くす構造が採用されていた。 Since the connecting portion between the upper edge of the dash side panel and the pillar panel is located immediately in front of the driver's seat and the passenger seat, it is also an important portion in the NVH performance of the automobile, particularly in silence (noise level reduction). . Conventionally, at the joint portion between the upper edge portion of the dash side panel and the pillar panel, the shape of the upper edge portions 721, 722, 723 of the dash side panel 72 is formed as a pillar as shown in FIG. By following the pillar portions 731 and 732 and the window opening flange portion 733 of the panel 73, or by causing the upper edge portion 823 of the dash side panel 82 to follow the shape of the lower portion 834 of the pillar panel 83 as shown in FIG. The structure which eliminated the clearance gap between members was employ | adopted.

しかし、これらの結合形態では、何れか一方（７２，８３）の形状が複雑になり、部品の重量が増加したり、歩留まりが悪化したりする問題があった。特に、図７，８に示した例のように、フロントピラー部に三角窓７３０，８３０が設定される車両では、フロントピラーの下部（７３１，７３２，８３１，８３２）が前後２つに分岐しているので、この傾向が一層顕著になる。 However, in these coupling forms, there is a problem that the shape of either one (72, 83) becomes complicated, and the weight of parts increases or the yield deteriorates. In particular, as in the example shown in FIGS. 7 and 8, in a vehicle in which triangular windows 730 and 830 are set in the front pillar portion, the lower portion (731, 732, 831, 832) of the front pillar branches into two front and rear. Therefore, this tendency becomes more remarkable.

さらに、図８に示した結合形態では、ダッシュサイドパネル８２の上縁部８２３とピラーパネル８３との溶接が、ピラーパネル下部８３４の外面側に接合される他部品８４との干渉によって直ちに実施できないので、ダッシュサイドパネル８２の中間に開口部８２０を設け、この開口部８２０から図示しない溶接ガンを挿入してスポット溶接していた。そのため、溶接工程の後で開口部８２０を塞ぐ遮音材などを別部品として追加しなければならない問題があった。 Further, in the coupling form shown in FIG. 8, welding between the upper edge portion 823 of the dash side panel 82 and the pillar panel 83 cannot be immediately performed due to interference with other parts 84 joined to the outer surface side of the pillar panel lower portion 834. Therefore, an opening 820 is provided in the middle of the dash side panel 82, and a welding gun (not shown) is inserted through the opening 820 to perform spot welding. Therefore, there has been a problem that a sound insulating material or the like for closing the opening 820 must be added as a separate part after the welding process.

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、部品形状の複雑化とそれに伴う重量増加や歩留まり悪化を回避しつつ、静粛性を確保するうえで有利なフロントピラー基部周辺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 an object of the present invention is to provide a front pillar that is advantageous in ensuring quietness while avoiding complication of part shape and accompanying weight increase and yield deterioration. It is to provide a base peripheral structure.

上記従来技術の有する課題を解決するため、本発明は、ダッシュサイドパネル（２）と、前記ダッシュサイドパネルの車両室外側に接合される下部（３４）およびその上方に延びるピラー部（３１，３２）を有するピラーパネル（３）と、を備え、前記ダッシュサイドパネルの上縁部（２１）とその車両室外側に位置した前記ピラーパネルとの間の間隙を塞ぐフロントピラーモール（４）が装着されている、自動車のフロントピラー基部周辺構造にある。 In order to solve the above-described problems of the prior art, the present invention includes a dash side panel (2), a lower part (34) joined to the vehicle compartment outside of the dash side panel, and a pillar part (31, 32) extending above the dash side panel. And a pillar panel (3) having a front pillar molding (4) for closing a gap between the upper edge (21) of the dash side panel and the pillar panel located outside the vehicle compartment. In the structure around the front pillar base of the automobile.

本発明に係る自動車のフロントピラー基部周辺構造は、上記構成により、以下に記載されるような効果を奏する。 The structure around the front pillar base of the automobile according to the present invention has the following effects due to the above configuration.

ダッシュサイドパネル（２）の上縁部（２１）とその車両室外側に位置したピラーパネル（３，３１）との間の間隙を塞ぐフロントピラーモール（４）を設定することで、ダッシュサイドパネル上縁部（２１）とピラーパネル（３）との接合部分に良好な密閉性を確実に得ることができる。 By setting the front pillar molding (4) that closes the gap between the upper edge (21) of the dash side panel (2) and the pillar panel (3, 31) located outside the vehicle compartment, the dash side panel Good sealing properties can be reliably obtained at the joint between the upper edge (21) and the pillar panel (3).

そのため、接合部分の密閉性を確保するために、ダッシュサイドパネル上縁部（２１）およびピラーパネル（３）のパネル形状を厳密に一致させる必要がなくなり、例えば、ピラーパネル（３）に関しては強度性能を優先した立体的なパネル形状を選択しても、ダッシュサイドパネル上縁部（２１）に関しては成形性を優先した簡素なパネル形状を選定可能となり、パネル形状の複雑化に伴う重量増加や歩留まり悪化を回避しつつ、自動車のＮＶＨ性能、特に、静粛性（騒音レベル低減）を確保することが可能となる。 Therefore, it is not necessary to match the panel shape of the upper edge portion (21) of the dash side panel and the pillar panel (3) in order to ensure the sealing property of the joint portion. For example, the strength of the pillar panel (3) is increased. Even if you select a three-dimensional panel shape that prioritizes performance, you can select a simple panel shape that prioritizes formability for the upper edge (21) of the dash side panel, It is possible to ensure the NVH performance of the automobile, in particular, quietness (noise level reduction) while avoiding yield deterioration.

フロントピラーモール（４）は、一般的なモール類がそうであるように、樹脂成形品とすることで、安価かつ軽量でありながら高い寸法精度が得られ、しかも、金属薄板のプレス成形部品であるダッシュサイドパネル（２）やピラーパネル（３）との間に良好な密着性が得られるうえ、フロントピラーモール自体の固定や係止のための構造、および、最終的にフロントピラーモールの表面上に装着される内装材など他部品の位置決め若しくは固定や係止のための構造を容易に形成でき、フロントピラーモール１個分の部品点数およびコスト増加を補って余りある利点がある。 The front pillar molding (4) is a resin molded product, as is the case with general moldings, so that it is inexpensive and lightweight, and high dimensional accuracy can be obtained. Good adhesion to a dash side panel (2) and pillar panel (3) is obtained, and the structure for fixing and locking the front pillar molding itself, and finally the surface of the front pillar molding A structure for positioning, fixing, or locking other parts such as an interior material mounted on the top can be easily formed, and there is an advantage that the number of parts for one front pillar molding and the cost increase are more than compensated.

また、本発明の好適な態様では、前記フロントピラーモール（４）および前記ダッシュサイドパネルの前記上縁部（２１）を貫通する貫通孔（４１０，２１０）に挿通された結合部材（５）により、前記フロントピラーモール（４）が前記上縁部（２１）に固定されている。 In a preferred aspect of the present invention, the coupling member (5) inserted through the front pillar molding (4) and the through holes (410, 210) penetrating the upper edge (21) of the dash side panel. The front pillar molding (4) is fixed to the upper edge (21).

この態様では、ダッシュサイドパネル上縁部（２１）に対するフロントピラーモール（４）の固定が１つの結合部材（５）で達成され、フロントピラーモール（４）の組付け性が良好であるとともに、フロントピラーモール（４）の固定のための構造が、ダッシュサイドパネル上縁部（２１）の貫通孔（２１０）のみからなり、成形性および製造コスト面で有利である。 In this aspect, the fixing of the front pillar molding (4) to the upper edge (21) of the dash side panel is achieved by one coupling member (5), and the assembly property of the front pillar molding (4) is good, The structure for fixing the front pillar molding (4) consists only of the through hole (210) of the upper edge (21) of the dash side panel, which is advantageous in terms of formability and manufacturing cost.

また、本発明の他の好適な態様では、前記フロントピラーモール（４）、前記ダッシュサイドパネルの前記上縁部（２１）、および、前記ピラーパネル（３，３１）を貫通する貫通孔（４１０，２１０，３１０）に挿通された結合部材（５）により、前記フロントピラーモール（４）が前記上縁部（２１）に固定され、かつ、前記ダッシュサイドパネルの前記上縁部（２１）と前記ピラーパネル（３，３１）とが相互に結合されている。 In another preferred aspect of the present invention, the front pillar molding (4), the upper edge (21) of the dash side panel, and the through-hole (410) that penetrates the pillar panel (3, 31). , 210, 310), the front pillar molding (4) is fixed to the upper edge (21) by the coupling member (5) inserted through the upper edge (21) of the dash side panel. The pillar panels (3, 31) are coupled to each other.

この態様では、フロントピラーモール（４）の固定と、ダッシュサイドパネル上縁部（２１）とピラーパネル（３，３１）の相互結合が、１つの結合部材（５）で達成され、組付け性および結合安定性、密閉性の点で有利である。特に、閉断面を画成するピラーパネル（３，３１）は、両側のフランジ部以外にスポット溶接の溶接点を設けることができない（従来はボルトとウエルドナットで結合されていた）が、この部分の結合をフロントピラーモール（４）の固定と共通の結合部材（５）で同時に行うことで、フロントピラーモールの追加による実質的な組付け工数の増加は生じないばかりか、ボルトヘッドなどに比べて面積の大きいフロントピラーモール（４）を介して結合がなされることで、ダッシュサイドパネル上縁部（２１）とピラーパネル（３）との接合部分の広範囲に亘って結合力を作用させることができ有利である。 In this aspect, the fixing of the front pillar molding (4) and the mutual connection between the upper edge portion (21) of the dash side panel and the pillar panel (3, 31) are achieved by one connecting member (5). In addition, it is advantageous in terms of bond stability and sealability. In particular, the pillar panel (3, 31) that defines a closed cross-section cannot be provided with spot-welded welding points other than the flanges on both sides (previously connected with bolts and weld nuts). By combining the front pillar molding (4) and the common coupling member (5) at the same time, the addition of the front pillar molding does not cause a substantial increase in assembly man-hours. The coupling force is applied over a wide range of the joint portion between the upper edge (21) of the dash side panel and the pillar panel (3) by being coupled through the front pillar molding (4) having a large area. This is advantageous.

また、本発明のさらに好適な態様では、前記フロントピラーモール（４）の裏面側に、前記ダッシュサイドパネルの上縁部（２１）と前記ピラーパネル（３，３１）との間の前記隙間に係入される係入片（４８）が、前記結合部材（５）の挿通方向と交差する方向に突設されている。 In a further preferred aspect of the present invention, the gap between the upper edge (21) of the dash side panel and the pillar panel (3, 31) is provided on the back side of the front pillar molding (4). Engagement pieces (48) to be engaged are projected in a direction intersecting with the insertion direction of the coupling member (5).

この態様では、フロントピラーモール（４）が係入片（４８）でダッシュサイドパネルの上縁部（２１）に係止されることで、結合部材（５）に抜脱方向の力が作用するのが防止され、結合部材（５）の負担が軽減されるので、結合部材（５）として、貫通孔に押し込んで係止する方式のクリップを用いる場合に有利である。また、フロントピラーモール（４）の組付け時に、係入片（４８）によって、結合部材（５）を挿通する以前にフロントピラーモール（４）が仮止めされる利点もある。 In this aspect, the front pillar molding (4) is locked to the upper edge (21) of the dash side panel by the engaging piece (48), so that a force in the removal direction acts on the coupling member (5). Therefore, it is advantageous when a clip of the type that is pushed into the through hole and locked is used as the coupling member (5). Further, when the front pillar molding (4) is assembled, the front pillar molding (4) is also temporarily fixed by the engaging piece (48) before the coupling member (5) is inserted.

また、本発明の他の好適な態様では、前記ピラーパネルは窓開口（３０）を有し、前記ピラー部は、前記窓開口の前方に位置した前ピラー部（３１）と、前記窓開口の後方に位置した後ピラー部（３２）とを含み、前記ダッシュサイドパネルの前記上縁部は、前記前ピラー部に沿った上縁前部（２１）と、前記後ピラー部に沿った上縁後部（２２）と、前記上縁前部と前記上縁後部との間で前記窓開口の下辺に沿って延在する上縁中間部（２３）とを含み、前記上縁中間部にて、前記ピラーパネルの前記窓開口の下辺をなす窓開口フランジ部（３３）に溶接接合され、前記上縁前部（２１）は、略車両前後方向に延在する第１縁部（２１ａ）と、その後端から略車幅方向外方に延びて前記窓開口フランジ部に至る第２縁部（２１ｂ）を含み、前記フロントピラーモール（４）は、前記第１縁部に対応した第１部分（４１）と、前記第２縁部に対応した第２部分（４２）とで略Ｌ字形状に形成されている。 In another preferred aspect of the present invention, the pillar panel includes a window opening (30), and the pillar portion includes a front pillar portion (31) positioned in front of the window opening, and the window opening. A rear pillar portion (32) located rearward, and the upper edge portion of the dash side panel includes an upper edge front portion (21) along the front pillar portion and an upper edge along the rear pillar portion. A rear portion (22) and an upper edge intermediate portion (23) extending along the lower side of the window opening between the upper edge front portion and the upper edge rear portion, and at the upper edge intermediate portion, The upper edge front portion (21) is welded to the window opening flange portion (33) forming the lower side of the window opening of the pillar panel, and the first edge portion (21a) extending substantially in the vehicle front-rear direction; A second edge (21b) extending from the rear end substantially outward in the vehicle width direction to reach the window opening flange, The front pillar molding (4) is formed in a substantially L shape with a first portion (41) corresponding to the first edge and a second portion (42) corresponding to the second edge. .

フロントピラーに窓が設定される車体では、ダッシュサイドパネル上縁部（２１，２２，２３）が、ピラーパネル（３）の前後２つのピラー部（３１，３２）と重なるので、パネル形状が複雑化する（図７）、スポット溶接のための開口が必要になる（図８）等の問題があったが、断面形状が大きく傾斜や屈曲が大きい前ピラー部（３１）にフロントピラーモール（４）が設定されることで、ダッシュサイドパネル上縁部のパネル形状を簡素化することが可能になるとともに、溶接工程が簡略化される利点がある。また、フロントピラーモール（４）が、前ピラー部（３１）に対応した略Ｌ字形状に形成されることで、フロントピラーモール自体の強度や密着性が向上する利点もある。 In the vehicle body in which a window is set in the front pillar, the upper edge (21, 22, 23) of the dash side panel overlaps the two front and rear pillars (31, 32) of the pillar panel (3), so the panel shape is complicated. (FIG. 7), there is a problem that an opening for spot welding is required (FIG. 8), but the front pillar molding (4) is formed on the front pillar portion (31) having a large cross-sectional shape and a large inclination and bending. ) Is set, it is possible to simplify the panel shape of the upper edge portion of the dash side panel and to simplify the welding process. Moreover, there exists an advantage which the intensity | strength and adhesiveness of front pillar molding itself improve because a front pillar molding (4) is formed in the substantially L shape corresponding to a front pillar part (31).

以下、本発明の実施の形態について、図面を参照しながら詳細に説明する。
図１及び図３は、内装材等を除去した自動車のフロントピラー基部周辺を車室内後方すなわち運転席側から見た斜視図である。各図において、自動車の車室前部はダッシュパネル１によってエンジン室側と区画され、ダッシュパネル１の左右両側には、車体側壁の室内側の面を構成するダッシュサイドパネル２が接合されている。なお、ダッシュパネル１の上部にカウルトップパネルが接合される場合等には、ダッシュサイドパネル２がカウルサイドパネルと呼ばれることもある。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 3 are perspective views of the vicinity of a front pillar base portion of an automobile from which interior materials and the like are removed as viewed from the rear of the vehicle interior, that is, from the driver's seat side. In each figure, the front part of the passenger compartment of the automobile is partitioned from the engine compartment side by a dash panel 1, and the dash side panel 2 constituting the interior side surface of the vehicle body side wall is joined to the left and right sides of the dash panel 1. . In addition, when a cowl top panel is joined to the upper part of the dash panel 1, the dash side panel 2 may be called a cowl side panel.

ダッシュサイドパネル２は、前方側の縁部においてダッシュパネル１に接合され、後方側の縁部には、ドア開口フランジの一部を構成するフランジ部２５が形成されている。さらに、ダッシュサイドパネル２の上縁部（２１，２２，２３）は、窓開口３０の下辺をなす中間部２３（窓開口フランジ部）と、その前方に位置した上縁前部２１、後方に位置した上縁後部２２の３つの部分で構成されている。 The dash side panel 2 is joined to the dash panel 1 at an edge on the front side, and a flange portion 25 constituting a part of the door opening flange is formed at the edge on the rear side. Furthermore, the upper edge portions (21, 22, 23) of the dash side panel 2 are an intermediate portion 23 (window opening flange portion) that forms the lower side of the window opening 30, an upper edge front portion 21 positioned in front thereof, and a rear portion. It consists of three parts, the upper edge rear part 22 located.

これらのうち、中間部２３は、ダッシュサイドパネル２の中央部およびフランジ部２５に対して、フロントピラー（後述する前ピラー部３１）の立体的断面形状（３１ｂ）の分だけ車幅方向外方に延出した部分から立ち上げられており、それに伴い、図３に示すように、上縁前部２１は、車両前後方向に延びる第１縁部２１ａとその後端から車幅方向外方に延びて中間部２３の前端に至る第２縁部２１ｂを含み、また、上縁後部２２は、フランジ部２５の上端から前上方に延びその上端側で車幅方向外方に延びて中間部２３の後端に至っている。 Among these, the intermediate portion 23 is outward in the vehicle width direction with respect to the central portion of the dash side panel 2 and the flange portion 25 by the three-dimensional cross-sectional shape (31b) of the front pillar (the front pillar portion 31 described later). Accordingly, as shown in FIG. 3, the upper edge front portion 21 extends outwardly in the vehicle width direction from the first edge portion 21a extending in the vehicle longitudinal direction and the rear end thereof. The upper edge rear portion 22 extends from the upper end of the flange portion 25 to the front upper side and extends outward in the vehicle width direction at the upper end side of the intermediate portion 23 to reach the front end of the intermediate portion 23. It reaches the rear end.

ダッシュサイドパネル２の室外側には、図示しないヒンジリンフォースを挟んで、ほぼ同じ外形状のピラーパネル３の下部３４（３３，３５）が接合されている。ピラーパネル３の上部は、ダッシュサイドパネル２の上縁部（２１，２２）を越えて上方に延びる前ピラー部３１および後ピラー部３２となっており、それらの中間に窓開口３０が形成されている。前ピラー部３１と後ピラー部３２は図示しない上部で一体となってルーフサイドに連続している。 The lower part 34 (33, 35) of the pillar panel 3 having substantially the same outer shape is joined to the outdoor side of the dash side panel 2 with a hinge reinforcement (not shown) interposed therebetween. The upper portion of the pillar panel 3 is a front pillar portion 31 and a rear pillar portion 32 that extend upward beyond the upper edges (21, 22) of the dash side panel 2, and a window opening 30 is formed between them. ing. The front pillar portion 31 and the rear pillar portion 32 are integrated at an upper portion (not shown) and are continuous with the roof side.

前ピラー部３１は、側面３１ａとその後側に連続した後面３１ｂを含む断面略Ｌ字状に形成されており、側面３１ａが、ダッシュサイドパネル２の上縁前部２１における第１縁部２１ａに隣接し、後面３１ｂが第２縁部２１ｂに隣接している。しかし、これら側面３１ａおよび後面３１ｂに、ダッシュサイドパネル上縁前部２１の第１縁部２１ａおよび第２縁部２１ｂが完全に接しているのではなく、図３および図４（ａ）に示す第１実施形態では、第１縁部２１ａの段差部２１ｄ（車両室外側への膨出部）に最接近する側面３１ａの膨出部３１ｄを含む隣接区間全域に隙間２１ｃが形成されている。代替的に、図４（ｂ）に示す第２実施形態では、第１縁部２１ａの段差部２１ｄに側面３１ａの膨出部３１ｄを当接させ、それ以外の部分に隙間２１ｃが形成されるようにしている。 The front pillar portion 31 is formed in a substantially L-shaped cross section including a side surface 31a and a rear surface 31b continuous to the rear side, and the side surface 31a is formed on the first edge portion 21a in the upper edge front portion 21 of the dash side panel 2. Adjacent and the rear surface 31b is adjacent to the second edge 21b. However, the side surface 31a and the rear surface 31b are not completely in contact with the first edge portion 21a and the second edge portion 21b of the upper edge front portion 21 of the dash side panel, but are shown in FIGS. 3 and 4A. In 1st Embodiment, the clearance gap 21c is formed in the adjacent area whole region including the swelling part 31d of the side surface 31a which is closest to the level | step-difference part 21d (bulging part to the vehicle compartment outer side) of the 1st edge part 21a. Alternatively, in the second embodiment shown in FIG. 4B, the bulged portion 31d of the side surface 31a is brought into contact with the stepped portion 21d of the first edge portion 21a, and a gap 21c is formed in the other portion. I am doing so.

ピラーパネル３の前後ピラー部３１，３２は、ピラーパネル３の下部３４から上述したような立体的な断面形状をなして上方に延び、しかも、前ピラー部３１は、フロントウインドウの傾斜に対応して、車両後方側に傾斜して立ち上がっているため、窓開口３０の前下方の角部に位置した前ピラー部３１の後面３１ｂはやや鋭角的に屈曲して上方に延びている。ダッシュサイドパネル２の上縁前部２１も、前ピラー部３１の基部に応じた立体的断面形状をなして前上方に立ち上がっているが、特に第２縁部２１ｂを前ピラー部３１の後面３１ｂに完全に追従させるには、より大きな屈曲が必要となり、その場合、成形性が悪化することになる。 The front and rear pillar portions 31 and 32 of the pillar panel 3 extend upward from the lower portion 34 of the pillar panel 3 in the three-dimensional cross section as described above, and the front pillar portion 31 corresponds to the inclination of the front window. Thus, the rear surface 31b of the front pillar portion 31 located at the front lower corner of the window opening 30 is bent at a slightly acute angle and extends upward. The upper edge front portion 21 of the dash side panel 2 also has a three-dimensional cross-sectional shape corresponding to the base portion of the front pillar portion 31 and rises frontward and upward. In particular, the second edge portion 21b is raised to the rear surface 31b of the front pillar portion 31. In order to make it follow completely, a bigger bending | flexion is required, In that case, a moldability will deteriorate.

そこで、ダッシュサイドパネル２の第２縁部２１ｂは、図３に示すように、前ピラー部３１の後面３１ｂに向かって前上方に延びたままの傾斜角度で終端させることで、隙間２１ｃは残るものの、成形性の悪化を回避し、また、前ピラー部３１の側面３１ａと、ダッシュサイドパネル上縁前部２１の第１縁部２１ａも、隙間２１ｃを残すことでパネル形状を簡素にする一方、隙間２１ｃを閉鎖してＮＶＨ性能を確保するために、前ピラー部３１の基部とダッシュサイドパネル２の上縁前部２１との境界部分に沿ってフロントピラーモール４が設定されている。 Therefore, as shown in FIG. 3, the second edge portion 21b of the dash side panel 2 is terminated at an inclination angle that extends forward and upward toward the rear surface 31b of the front pillar portion 31, so that the gap 21c remains. However, the deterioration of formability is avoided, and the side surface 31a of the front pillar portion 31 and the first edge portion 21a of the upper edge front portion 21 of the dash side panel also simplify the panel shape by leaving the gap 21c. In order to close the gap 21c and ensure NVH performance, the front pillar molding 4 is set along the boundary portion between the base portion of the front pillar portion 31 and the upper edge front portion 21 of the dash side panel 2.

フロントピラーモール４は、樹脂成形品で構成され、ダッシュサイドパネル上縁前部２１の第１縁部２１ａおよび前ピラー部３１の側面３１ａに対応した第１部分４１と、ダッシュサイドパネル上縁前部２１の第２縁部２１ｂおよび前ピラー部３１の後面３１ｂに対応した第２部分４２とを含み、図１〜図４および図６に示されるように、平面視において略Ｌ字形状に形成されている。 The front pillar molding 4 is formed of a resin molded product, and includes a first portion 41 corresponding to the first edge portion 21a of the upper edge front portion 21 of the dash side panel and the side surface 31a of the front pillar portion 31, and the front edge of the upper side of the dash side panel. 2 and a second portion 42 corresponding to the rear surface 31b of the front pillar portion 31, and formed in a substantially L shape in plan view as shown in FIGS. Has been.

フロントピラーモール４の第１部分４１は、ダッシュサイドパネル上縁前部２１の第１縁部２１ａに対応した側壁部４３と、その上側から段部４７を介して前ピラー部３１の側面３１ａに向かって張出した第１張出部４５とを含み、側壁部４３のほぼ中央には貫通孔４１０が設けられ、貫通孔４１０の周囲には、後述するクリップ５の頭部が収容される座面が形成されている。また、側壁部４３には、格子状に補強リブ４３ａが一体成形されており、このうち、上下方向の補強リブは段部４７を経て第１張出部４５の基部に達している。また、第１張出部４５の前端には室内側に向かって湾曲した前端縁４５ａが形成されている。 The first portion 41 of the front pillar molding 4 is formed on the side wall portion 43 corresponding to the first edge portion 21a of the upper edge front portion 21 of the dash side panel and on the side surface 31a of the front pillar portion 31 through the stepped portion 47 from the upper side. A first projecting portion 45 projecting toward the center, and a through hole 410 is provided substantially at the center of the side wall portion 43, and a seat surface in which the head of the clip 5 described later is accommodated around the through hole 410. Is formed. In addition, reinforcing ribs 43 a are integrally formed on the side wall 43 in a lattice shape, and among these, the reinforcing ribs in the vertical direction reach the base of the first overhanging portion 45 through the stepped portion 47. In addition, a front end edge 45 a that is curved toward the indoor side is formed at the front end of the first overhang portion 45.

フロントピラーモール４の第２部分４２は、ダッシュサイドパネル上縁前部２１の第２縁部２１ｂに対応した後壁部４４と、その上側から前ピラー部３１の後面３１ｂに向かって上方に張出した第２張出部４６とを含み、後壁部４４の裏面側には、図５に示されるように、前ピラー部３１の後面３１ｂの傾斜角に沿って斜前下方に突出した係入片４８が形成されている。 The second portion 42 of the front pillar molding 4 protrudes upward from the rear wall portion 44 corresponding to the second edge portion 21b of the upper edge front portion 21 of the dash side panel and from the upper side toward the rear surface 31b of the front pillar portion 31. The second overhanging portion 46 and the rear wall portion 44 on the back surface side, as shown in FIG. 5, projecting forward obliquely downward along the inclination angle of the rear surface 31 b of the front pillar portion 31. A piece 48 is formed.

フロントピラーモール４の車体への取付けに際しては、第２部分４２の係入片４８を、ダッシュサイドパネル上縁前部２１の第２縁部２１ｂと前ピラー部３１の後面３１ｂとの間の隙間２１ｃに係入し、後壁部４４を第２縁部２１ｂに重ね、かつ、第１部分４１の段部４７を、ダッシュサイドパネル上縁前部２１の第１縁部２１ａの上に被せるとともに側壁部４３を第１縁部２１ａに重ねた状態で、図４（ａ）に示す第１実施形態では、クリップ５の先端部を貫通孔４１０から押し込み、ダッシュサイドパネル上縁前部２１の段差部２１ｄの貫通孔２１０に貫通させた状態で係止する。 When the front pillar molding 4 is attached to the vehicle body, the engaging piece 48 of the second portion 42 is formed with a gap between the second edge portion 21b of the upper edge front portion 21 of the dash side panel and the rear surface 31b of the front pillar portion 31. 21c, the rear wall portion 44 is overlapped with the second edge portion 21b, and the step portion 47 of the first portion 41 is covered on the first edge portion 21a of the front edge portion 21 of the upper edge of the dash side panel. In the first embodiment shown in FIG. 4A with the side wall portion 43 overlapped with the first edge portion 21a, the step of the dash side panel upper edge front portion 21 is pushed by pushing the tip portion of the clip 5 from the through hole 410. It latches in the state penetrated to the through-hole 210 of the part 21d.

これにより、フロントピラーモール４がダッシュサイドパネル２の上縁前部２１に密着した状態で固定され、フロントピラーモール４の各張出部４５，４６および前端縁４５ａが前ピラー部３１に密着されることで、隙間２１ｃが塞がれる。この際、貫通孔２１０の背後に位置した前ピラー部３１の膨出部３１ｄに形成された大径の貫通孔３１０（逃げ孔）により、ダッシュサイドパネル２の上縁前部２１と前ピラー部３１との隙間２１ｃが比較的狭い場合でも、クリップ５の先端と前ピラー部３１（膨出部３１ｄ）との干渉が防止される。フロントピラーモール４は樹脂成形品で構成されているので、安価かつ軽量で寸法精度が高い上、鋼板製のダッシュサイドパネル２や前ピラー部３１との密着性も良好であり、かつ、鋼板の塗装面を損傷することもない。 Thereby, the front pillar molding 4 is fixed in a state of being in close contact with the upper edge front portion 21 of the dash side panel 2, and the overhang portions 45 and 46 and the front end edge 45 a of the front pillar molding 4 are in close contact with the front pillar portion 31. As a result, the gap 21c is closed. At this time, the upper edge front portion 21 of the dash side panel 2 and the front pillar portion are formed by a large-diameter through hole 310 (escape hole) formed in the bulging portion 31d of the front pillar portion 31 located behind the through hole 210. Even when the gap 21c with respect to 31 is relatively narrow, interference between the tip of the clip 5 and the front pillar portion 31 (the bulging portion 31d) is prevented. Since the front pillar molding 4 is made of a resin molded product, it is inexpensive and lightweight, has high dimensional accuracy, has good adhesion to the dash side panel 2 made of steel plate and the front pillar portion 31, and The painted surface is not damaged.

また、クリップ５を押し込み係止する取付け作業そのものが簡単なことに加えて、取付け作業時に、段部４７と係入片４８によって、フロントピラーモール４がダッシュサイドパネル２の上縁前部２１に仮止めされるので、取付け作業が一層容易になる。なお、段部４７の下面に、ダッシュサイドパネル上縁前部２１の裏面側に係入する係入片（リブや突起など）を設けても良い。これらの係入片が、クリップ５の押し込み方向と交差する方向に突設され係入されることで、フロントピラーモール４の取付け状態で、クリップ５の抜脱方向に作用する力が低減される利点がある。 In addition to the fact that the mounting operation itself for pushing and locking the clip 5 is simple, the front pillar molding 4 is attached to the upper edge front portion 21 of the dash side panel 2 by the stepped portion 47 and the engaging piece 48 during the mounting operation. Since it is temporarily fixed, the installation work becomes easier. An engaging piece (such as a rib or a protrusion) that engages with the back surface of the front edge 21 of the upper edge of the dash side panel may be provided on the lower surface of the stepped portion 47. Since these engaging pieces project and project in a direction intersecting the pushing direction of the clip 5, the force acting in the pulling-out direction of the clip 5 is reduced in the attached state of the front pillar molding 4. There are advantages.

また、図４（ｂ）に示す第２実施形態では、クリップ５の先端部を貫通孔４１０から押し込み、ダッシュサイドパネル上縁前部２１の段差部２１ｄおよび前ピラー部３１の膨出部３１ｄの貫通孔２１０，３１０に貫通させた状態で係止することにより、フロントピラーモール４がダッシュサイドパネル２の上縁前部２１と前ピラー部３１とに密着した状態で固定され、隙間２１ｃが塞がれると同時に、ダッシュサイドパネル２の上縁前部２１（段差部２１ｄ）と前ピラー部３１（膨出部３１ｄ）とが、クリップ５で結合される。 In the second embodiment shown in FIG. 4B, the tip of the clip 5 is pushed from the through hole 410, and the stepped portion 21d of the upper edge front portion 21 of the dash side panel and the bulging portion 31d of the front pillar portion 31 are formed. The front pillar molding 4 is fixed in a state of being in close contact with the upper edge front portion 21 and the front pillar portion 31 of the dash side panel 2 by being locked in a state of being penetrated through the through holes 210 and 310, and the gap 21c is closed. At the same time, the upper edge front portion 21 (stepped portion 21 d) and the front pillar portion 31 (bulged portion 31 d) of the dash side panel 2 are joined by the clip 5.

この第２実施形態では、前ピラー部３１の膨出部３１ｄと、ダッシュサイドパネル上縁前部２１の段差部２１ｄとが当接し、かつ、各貫通孔２１０，３１０が一致するように寸法精度を確保する必要があるものの、凸面（膨出部３１ｄと段差部２１ｄ）同士の当接は、各パネル（２１，３１）の縁部（２１ａ，３１ａ）を追従させる場合に比べれば、容易に寸法精度が得られるので、成形性に大きく影響することはない。また、貫通孔２１０，３１０の何れか一方をルーズホールにして、誤差が吸収されるようにしても良い。 In the second embodiment, the dimensional accuracy is such that the bulging portion 31d of the front pillar portion 31 and the stepped portion 21d of the upper edge front portion 21 of the dash side panel are in contact with each other, and the through holes 210 and 310 are coincident. However, the contact between the convex surfaces (the bulged portion 31d and the stepped portion 21d) is easier than when the edges (21a, 31a) of the panels (21, 31) are followed. Since dimensional accuracy is obtained, the moldability is not greatly affected. Further, any one of the through holes 210 and 310 may be a loose hole so that the error is absorbed.

以上、本発明の実施の形態について述べたが、本発明は上記各実施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さらに各種の変形および変更が可能である。 As mentioned above, although embodiment of this invention was described, this invention is not limited to said each embodiment, Based on the technical idea of this invention, a various deformation | transformation and change are further possible.

例えば、上記各実施形態では、フロントピラーモール４の結合部材に押し込み式のクリップ５を用いる場合を示したが、貫通孔４１０，２１０，３１０を異形孔として押し回し方式のクリップを利用したり、早回しネジやビスを用いたりすることもできる。また、従来同様、結合部材にボルトとウエルドナットを用いることもできる。 For example, in each of the above embodiments, the case where the push-type clip 5 is used for the coupling member of the front pillar molding 4 has been shown. However, the through-hole 410, 210, 310 is used as a deformed hole, and a clip of the push-type method is used. You can also use a fast turn screw or screw. Further, as in the prior art, a bolt and a weld nut can be used for the coupling member.

また、上記各実施形態では、窓開口３３と前後ピラー部３１，３２を有するフロントピラーの前ピラー部３１の基部にフロントピラーモール４を装着する場合を示したが、窓開口を有さない単一のピラーの基部にフロントピラーモールを設置することもできる。また、フロントピラーモールを、後ピラー部３２の基部（ダッシュサイドパネル２の上縁後部２２）にも設置可能である。但し、後ピラー部３２は前ピラー部３１に比べて断面形状が小さいうえ、屈曲角度も緩く、プレス成形によって充分な密着性が得られるので、上記各実施形態では設定されていない。 In each of the above embodiments, the case where the front pillar molding 4 is attached to the base of the front pillar portion 31 of the front pillar having the window opening 33 and the front and rear pillar portions 31 and 32 has been described. A front pillar molding can be installed at the base of one pillar. The front pillar molding can also be installed at the base of the rear pillar portion 32 (the upper edge rear portion 22 of the dash side panel 2). However, since the rear pillar portion 32 has a smaller cross-sectional shape than the front pillar portion 31 and has a gentle bending angle and sufficient adhesion can be obtained by press molding, it is not set in each of the above embodiments.
