Description
【０００１】[0001]
本考案は、成形部品の車体組付構造に関し、特に位置決めピンの先端形状の改 良に関するものである。 The present invention relates to a vehicle body assembly structure for molded parts, and more particularly to improvement of a tip shape of a positioning pin.
【０００２】[0002]
従来より、成形部品を車体に組み付ける組付構造として、例えば実開昭５９― １３６０１６号公報に開示されているように、成形部品としてのインストルメン トパネルの裏面に位置決めピンを一体に成形し、この位置決めピンを車体側の位 置決め孔に挿入してその先端に膨出形成された係合段部を位置決め孔の係合部に 係合させることによりインストルメントパネルを車体に位置決めし、この状態で インストルメントパネルを車体に組み付けるようにした組付構造が知られている 。 Conventionally, as an assembly structure for assembling a molded part to a vehicle body, for example, as disclosed in Japanese Utility Model Publication No. 59-136016, a positioning pin is integrally molded on the back surface of an instrument panel as a molded part, and The instrument panel is positioned in the vehicle body by inserting the positioning pin into the positioning hole on the vehicle body side and engaging the engagement step portion bulged at the tip of the positioning pin with the engaging portion of the positioning hole. There is a known assembly structure in which the instrument panel is assembled to the vehicle body.
【０００３】[0003]
ところが、上記の従来の組付構造では、位置決めピン先端の係合段部は、ピン 軸心を境に両側に膨出形成されていることから、インストルメントパネル成形時 にこの両係合段部によってアンダーカット部がピン軸心を境に両側に２箇所形成 され、このため、スライド型を上記アンダーカット部に対応して２つ設けなけれ ばインストルメントパネルを脱型することができなくなり、型構造が複雑になる という問題がある。 However, in the above-mentioned conventional assembly structure, the engagement step portion at the tip of the positioning pin is formed so as to bulge out on both sides with the pin axis as a boundary. As a result, undercuts are formed at two locations on both sides of the pin axis center. Therefore, unless two slide dies are provided corresponding to the undercuts, the instrument panel cannot be removed from the die. There is a problem that the structure becomes complicated.
【０００４】 また、上述の如く係合段部がピン軸心を境に両側に膨出形成されていると、組 付け後のインストルメントパネルを車体から取り外す際、位置決めピンを上下左 右に傾けてもどちらか一方の係合段部が係合していて両係合段部の係合状態を同 時に解除することが難しく、インストルメントパネルを車体から取り外し難いと いう問題もある。Further, as described above, when the engaging step portion is formed to bulge out on both sides of the pin axis, the positioning pin is tilted up, down, left, right when removing the assembled instrument panel from the vehicle body. However, there is also a problem that it is difficult to remove the instrument panel from the vehicle body because it is difficult to release the engaged state of both engagement step portions at the same time because either one of the engagement step portions is engaged.
【０００５】 本考案はかかる点に鑑みてなされたものであり、その目的とするところは、位 置決めピン先端に膨出形成された係合段部の形状を改良することにより、インス トルメントパネル等の成形部品の脱型を１つのスライド型で可能にして型構造の 簡素化を図るとともに、位置決めピンを一方向に傾けるだけで係合段部の係合を 容易に解除して成形部品を車体から簡単に取り外さんとすることにある。The present invention has been made in view of the above point, and an object of the present invention is to improve the shape of an engagement step portion that is bulged at the tip of the positioning pin to improve the instrument. Molding parts such as panels can be removed from one mold with a single slide mold to simplify the mold structure, and by simply tilting the positioning pin in one direction, the engagement of the engaging step can be easily released. To remove the car from the car body easily.
【０００６】[0006]
上記の目的を達成するため、本考案は、インストルメントパネル等の成形部品 に一体に成形された位置決めピンを車体に設けられた筒体の貫通孔に先端が該貫 通孔から突出するように挿入し、先端突出部に膨出形成された係合段部を上記筒 体のピン突出側開口端に係合させることにより上記成形部品を車体に位置決めし 、この状態で成形部品を車体に組み付ける組付構造を対象とし、次のような解決 手段を講じた。 In order to achieve the above-mentioned object, the present invention provides a positioning pin integrally molded with a molded part such as an instrument panel so that a tip of the positioning pin projects into the through hole of a cylinder provided in the vehicle body. The molded part is positioned on the vehicle body by inserting and engaging the engaging stepped portion bulged on the protruding portion with the open end of the cylindrical body on the pin protruding side, and in this state, the molded component is assembled to the vehicle body. The following solution measures were taken for the assembly structure.
【０００７】 すなわち、本考案の解決手段は、上記位置決めピンの係合段部をピン軸心を境 に片側にのみ設けたことを特徴とする。That is, the solution means of the present invention is characterized in that the engaging step portion of the positioning pin is provided only on one side with the pin axis as a boundary.
【０００８】[0008]
上記の構成により、本考案では、成形部品を組付けに際し車体に位置決めした 時、上記成形部品に一体に成形された位置決めピンは、車体に設けられた筒体の 貫通孔に先端が該貫通孔から突出するように挿入され、先端突出部に膨出形成さ れた係合段部が上記筒体のピン突出側開口端に係合せしめられる。 With the above structure, according to the present invention, when the molded part is positioned on the vehicle body during assembly, the positioning pin formed integrally with the molded part has a tip in the through hole of the tubular body provided on the vehicle body. The engaging step portion, which is inserted so as to project from the bulge and is formed to bulge on the distal end projecting portion, is engaged with the pin projecting side opening end of the cylindrical body.
【０００９】 この場合、上記位置決めピンの係合段部はピン軸心を境に片側にのみ設けられ ていることから、成形時に係合段部によってアンダーカット部はピン軸心を境に 片側にのみ１箇所形成され、したがって、スライド型は上記アンダーカット部に 対応して１つ設けるだけで成形部品の脱型が可能となって型構造が簡素になる。In this case, since the engaging step portion of the positioning pin is provided only on one side of the pin axis center, the undercut portion is formed on one side of the pin axis center by the engaging step portion during molding. Since only one slide die is provided corresponding to the undercut portion, the molded part can be removed from the die, and the die structure is simplified.
【００１０】 また、組付け後の成形部品を車体から取り外す際には、位置決めピンを一方向 に傾けるだけで係合段部の係合が容易に解除されることから、成形部品の車体か らの取外しが簡単になる。Further, when the molded part after assembly is removed from the vehicle body, the engagement of the engaging step portion can be easily released by simply tilting the positioning pin in one direction. Can be easily removed.
【００１１】[0011]
以下、本考案の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００１２】 図１および図２は成形部品としての樹脂製の自動車用バンパーＢを示し、該バ ンパーＢ上端の車幅方向中程には裏側に水平に延びる位置決めピン１が一体に成 形されている。該位置決めピン１には、図３に拡大詳示するように、係合段部３ が膨出形成され、本考案の特徴として、該係合段部３はピン軸心Ｃを境に片側（ 図３上半分）にのみ形成されている。1 and 2 show a resin-made automobile bumper B as a molded part, and a positioning pin 1 extending horizontally to the back side is integrally formed at the upper end of the bumper B in the vehicle width direction. ing. As shown in an enlarged detail in FIG. 3, the positioning pin 1 is formed with an engaging step portion 3 bulgingly formed. As a feature of the present invention, the engaging step portion 3 is located on one side of the pin axis C. It is formed only in the upper half of FIG.
【００１３】 一方、図４に示すように、上記バンパーＢが組み付けられる車体Ｍには、取付 孔ｍ1 が形成され、該取付孔ｍ1 には、貫通孔５を有する樹脂製の筒体７が基端 に形成されたフランジ８と、外周に形成された４個（図４には２個示してある） の弾性爪９，９，…との間に取付孔ｍ1 開口端縁を係止せしめて車体Ｍ内側（図 ４右側）に突出するように取り付けられている。該筒体７の先端側は先細テーパ 形状に形成され、この先細テーパ形状部１１には、図５に示すように、先端に開 口するスリット１３が複数（図５では１つのみ表われる）形成されていて、該各 スリット１３によって先細テーパ形状部１１がピン軸心Ｃと直交する外径方向に 撓むようになされている。On the other hand, as shown in FIG. 4, a mounting hole m1 is formed in a vehicle body M to which the bumper B is assembled, and a resin cylindrical body 7 having a through hole 5 is formed in the mounting hole m1 as a base. The edge of the mounting hole m1 is locked between the flange 8 formed at the end and the four elastic claws 9, 9, ... Formed on the outer periphery (two shown in FIG. 4). It is attached so as to project inside the vehicle body M (right side in FIG. 4). The tip side of the cylindrical body 7 is formed in a tapered shape, and the tapered portion 11 has a plurality of slits 13 (only one is shown in FIG. 5) that are opened at the tip, as shown in FIG. Each of the slits 13 is formed so that the tapered tapered portion 11 is bent in the outer diameter direction orthogonal to the pin axis C.
【００１４】 そして、上記バンパーＢを車体Ｍに組み付ける際には、位置決めピン１を筒体 ７の貫通孔５に先端が該貫通孔５から突出するように挿入する。この際、筒体７ の先細テーパ形状部１１が位置決めピン１の先端突出部に膨出形成された係合段 部３で外側に押し拡げられ、その後、この係合段部３が上記筒体７のピン突出側 開口端（先細テーパ形状部１１先端）１５に係合せしめられて上記バンパーＢが 車体Ｍに位置決めされる。そして、この状態でバンパーＢを車体Ｍに組み付ける ようになされている。Then, when the bumper B is assembled to the vehicle body M, the positioning pin 1 is inserted into the through hole 5 of the cylindrical body 7 so that the tip thereof projects from the through hole 5. At this time, the tapered tapered portion 11 of the tubular body 7 is pushed outward by the engaging step portion 3 formed to bulge on the tip projection of the positioning pin 1, and thereafter the engaging step portion 3 is moved to the tubular body. The bumper B is positioned on the vehicle body M by being engaged with the open end (the tip of the tapered tapered portion 11) 15 of the pin 7 of the bumper 7. Then, in this state, the bumper B is assembled to the vehicle body M.
【００１５】 このように、本実施例では、位置決めピン１の係合段部３をピン軸心Ｃを境に 片側にのみ形成していることから、成形時に形成されるアンダーカット部はピン 軸心Ｃを境に片側にのみ１箇所だけであり、これによりスライド型を上記アンダ ーカット部に対応して１つ設けるだけでバンパーＢを脱型でき型構造を簡素にす ることができる。As described above, in this embodiment, since the engagement step portion 3 of the positioning pin 1 is formed only on one side with the pin axis C as the boundary, the undercut portion formed at the time of molding is the pin axis. Since there is only one location on one side with the core C as a boundary, the bumper B can be demolded and the die structure can be simplified by providing only one slide die corresponding to the undercut portion.
【００１６】 なお、上述の如くして車体Ｍに組み付けられたバンパーＢを取り外す際には、 図６に示すように、位置決めピン１をピン先端部を支点として矢印Ａのように一 方向（上方）に傾ければよく、これにより先細テーパ形状部１１の下側を下方に 押し拡げながら上記係合段部３をピン突出側開口端（先細テーパ形状部１１先端 ）１５から外して係合状態を解除でき、その後はバンパーＢを手前に移動させて 位置決めピン１を筒体７の貫通孔５から引き抜くことによってバンパーＢを車体 Ｍから簡単に取り外すことができるのである。When removing the bumper B assembled to the vehicle body M as described above, as shown in FIG. 6, the positioning pin 1 is moved in one direction (upward direction) as shown by an arrow A with the pin tip portion as a fulcrum. ), Thereby pushing the lower side of the tapered tapered portion 11 downward and expanding the engaging stepped portion 3 from the pin protruding side opening end (the tapered tapered portion 11 tip) 15 After that, the bumper B can be easily removed from the vehicle body M by moving the bumper B forward and pulling out the positioning pin 1 from the through hole 5 of the cylindrical body 7.
【００１７】 なお、上記実施例では、位置決めピン１の係合段部３をピン軸心Ｃを境に上半 分に形成したが、ピン軸心Ｃを境に片側にのみ形成されていれば、半分よりも少 ない領域に形成されていてもよい。In the above embodiment, the engagement step portion 3 of the positioning pin 1 is formed in the upper half of the pin axis C, but it may be formed only on one side of the pin axis C. , May be formed in an area less than half.
【００１８】 また、上記実施例では、成形部品がバンパーＢである場合を示したが、これに 限らず、従来例のようなインストルメントパネルであってもよい。Further, although the case where the molded component is the bumper B is shown in the above-mentioned embodiment, the present invention is not limited to this, and an instrument panel as in a conventional example may be used.
【００１９】[0019]
