Description

この発明は、ドアの端末部に樹脂製の外装部材が設けられている車両のドア部構造に関するものである。   The present invention relates to a vehicle door portion structure in which a resin exterior member is provided at a terminal portion of a door.

ミニバン等の車両後部にテールゲート（バックドア）を備えた車両として、テールゲートの下方の端末部に、その端末部に沿った長尺状の外装部材が取り付けられたものが知られている。この種の車両においては、多くの場合、外装部材が樹脂材料によって一体に形成され、外装部材の外表面を車体のドア開口縁の外表面と同一高さまで滑らかに膨出させることにより、ドア部の端末形状が外観上、車体外表面と自然に連続するようになっている（例えば、特許文献１参照。）。
特開２００５−５９７８１号公報 2. Description of the Related Art As a vehicle having a tailgate (back door) at the rear part of a vehicle such as a minivan, a vehicle in which a long exterior member along the terminal part is attached to a terminal part below the tailgate is known. In this type of vehicle, in many cases, the exterior member is integrally formed of a resin material, and the outer surface of the exterior member is smoothly bulged to the same height as the outer surface of the door opening edge of the vehicle body. The terminal shape of the terminal is naturally continuous with the outer surface of the vehicle body in appearance (see, for example, Patent Document 1).

しかし、この従来のドア部構造においては、外装部材が一体の樹脂部品として形成されているため、樹脂部品の熱変形やその他の加工誤差等によって外装部材の長手方向に寸法誤差が生じ易く、この寸法誤差が大きくなると車体側のドア開口部との隙間寸法がばらつき、外観品質の低下を来たすことが懸念される。   However, in this conventional door portion structure, since the exterior member is formed as an integral resin part, a dimensional error tends to occur in the longitudinal direction of the exterior member due to thermal deformation of the resin part or other processing errors. When the dimensional error increases, there is a concern that the gap size with the door opening on the vehicle body side varies, resulting in a decrease in appearance quality.

また、前記のドア部構造の場合、外装部材を専用の成形型によって造形しなければならず、他部品からの外装部材の流用が難しい。このため、製造コストの高騰を招くことが懸念され、この点の改善が望まれている。   Moreover, in the case of the door part structure described above, the exterior member must be shaped with a dedicated mold, and it is difficult to divert the exterior member from other parts. For this reason, there is a concern that the manufacturing cost will increase, and improvement of this point is desired.

そこでこの発明は、樹脂製の外装部材の熱変形や加工誤差等に起因したドア側の部材と車体側ドア開口部との隙間寸法のばらつきを無くし、かつ、他の樹脂部材からの外装部品への流用を容易化して、車両の外観品質の向上と製造コストの低減を図ることのできる車両のドア部構造を提供しようとするものである。   Therefore, the present invention eliminates the variation in the gap size between the door-side member and the vehicle body-side door opening due to thermal deformation, processing error, etc. of the resin-made exterior member, and allows the exterior component to be made from other resin members. It is intended to provide a vehicle door portion structure that can facilitate the diversion of the vehicle and improve the appearance quality of the vehicle and reduce the manufacturing cost.

一方、テールゲート２の下端にはドア延長部材１０が取り付けられ、そのドア延長部材１０の表面側にロアガーニッシュ１１が取り付けられる。このロアガーニッシュ１１にはリヤバンパー６を切除した際の切除片が用いられる。 First, a substantially central portion of the rear bumper 6 is cut out over a set width, and a recess 12 is formed.
On the other hand, a door extension member 10 is attached to the lower end of the tailgate 2, and a lower garnish 11 is attached to the surface side of the door extension member 10. For the lower garnish 11, a cut piece obtained by cutting the rear bumper 6 is used.

ロアガーニッシュ１１の取り付けに際しては、ブラケット１５，１６や弾性部材２８が予めドア延長部材１０に取り付けられ、その状態でロアガーニッシュ１１が各ブラケット１５，１６にビス止めされ、その後に両側のカバー部材１９がドア延長部材１０に固定される。
このとき、各カバー部材１９は、内側係止フランジ２３と外側係止フランジ２２が夫々ドア延長部材１０の側端部１７とロアガーニッシュ１１の端部１８を覆うようにして両者１７，１８に嵌合され、その状態において取付ベース部２１がドア延長部材１０の前面にボルト２５によって結合される。このボルト２５のねじ込み作業はドア延長部材１０の裏面側から行われるが、ドア延長部材１０側のボルト挿通孔３０は車幅方向に延出する長孔となっており、ボルト締結はリヤバンパー６の凹部１２との幅方向の見切り幅を考慮してカバー部材１９の位置を長孔（ボルト挿通孔３０）の範囲内で微調整しつつ行われる。 When the lower garnish 11 is attached, the brackets 15 and 16 and the elastic member 28 are attached to the door extension member 10 in advance, and the lower garnish 11 is screwed to the brackets 15 and 16 in this state, and then the cover members 19 on both sides are attached. Is fixed to the door extension member 10.
At this time, each cover member 19 is fitted to both the ends 17 and 18 so that the inner locking flange 23 and the outer locking flange 22 cover the side end 17 of the door extension member 10 and the end 18 of the lower garnish 11, respectively. In this state, the mounting base portion 21 is coupled to the front surface of the door extension member 10 by bolts 25. The screw 25 is screwed in from the back side of the door extension member 10. The bolt insertion hole 30 on the door extension member 10 side is a long hole extending in the vehicle width direction, and the bolt is fastened by the rear bumper 6. This is performed while finely adjusting the position of the cover member 19 within the range of the long hole (bolt insertion hole 30) in consideration of the parting width in the width direction with respect to the concave portion 12.

この車両のテールゲート部においては、ドア延長部材１０の側端部１７とロアガーニッシュ１１の端部１８の各周囲がカバー部材１９の内側係止フランジ２３と外側係止フランジ２２によって覆われるため、ロアガーニッシュ１１の熱変形等による寸法誤差や組付け誤差によるばらつき代をカバー部材１９によって吸収しつつ、ロアガーニッシュ１１の側方とゲート開口部１との隙間精度を高めることができる。したがって、これによりテールゲート部の外観品質は確実に高まる。   In the tailgate portion of this vehicle, each periphery of the side end portion 17 of the door extension member 10 and the end portion 18 of the lower garnish 11 is covered by the inner locking flange 23 and the outer locking flange 22 of the cover member 19. The gap accuracy between the side of the lower garnish 11 and the gate opening 1 can be increased while absorbing the dimensional error due to thermal deformation of the lower garnish 11 and the variation due to the assembly error by the cover member 19. Therefore, this reliably increases the appearance quality of the tailgate portion.

また、このテールゲート部においては、カバー部材１９の取付ベース部２１がドア延長部材１０の前面にボルト結合されるため、カバー部材１９を、ドア延長部材１０を基準として正確にかつ強固に取り付けることができる。特に、この実施形態においては、ドア延長部材１０側のボルト挿通孔３０が長孔となっており、カバー部材１９のボルト結合時にカバー部材１９の取付位置を幅方向で微調整することができるため、ドア延長部材１０等に若干の製造誤差や組付け誤差があってもその誤差分を吸収し、テールゲート部の外観品質のさらなる向上を図ることができる。   Further, in this tailgate portion, the mounting base portion 21 of the cover member 19 is bolted to the front surface of the door extension member 10, so that the cover member 19 is attached accurately and firmly with reference to the door extension member 10. Can do. In particular, in this embodiment, the bolt insertion hole 30 on the door extension member 10 side is a long hole, and the attachment position of the cover member 19 can be finely adjusted in the width direction when the cover member 19 is bolted. Even if there is a slight manufacturing error or assembly error in the door extension member 10 or the like, the error can be absorbed and the appearance quality of the tailgate portion can be further improved.

さらに、この実施形態のテールゲート部の構造の場合、カバー部材１９が内側係止フランジ２３と外側係止フランジ２２でドア延長部材１０の側端部１７とロアガーニッシュ１１の端部１８に嵌合状態で支持されるため、カバー部材１９の位置ずれや変形を防止することができる。特に、この実施形態の場合、ドア延長部材１０側にあってはカバー部材１９がヘミング加工部１３に支持されるため、カバー部材１９の取付強度が高まり、カバー部材１９の位置ずれや変形がより確実に防止される。   Further, in the case of the structure of the tailgate portion of this embodiment, the cover member 19 is fitted to the side end portion 17 of the door extension member 10 and the end portion 18 of the lower garnish 11 by the inner locking flange 23 and the outer locking flange 22. Since the cover member 19 is supported in a state, it is possible to prevent the displacement and deformation of the cover member 19. In particular, in the case of this embodiment, since the cover member 19 is supported by the hemming portion 13 on the door extension member 10 side, the mounting strength of the cover member 19 is increased, and the displacement and deformation of the cover member 19 are further increased. It is surely prevented.

また、このテールゲート部においては、ロアガーニッシュ１１が長尺な板状の部材によって形成されるため、リヤバンパー６の切除片をロアガーニッシュ１１として流用することができ、特に少量生産の車両を製造する場合には、製造コストの大幅な低減を図ることが可能になる。   Further, in this tailgate portion, the lower garnish 11 is formed by a long plate-like member, so that a cut piece of the rear bumper 6 can be used as the lower garnish 11, and particularly a small-volume vehicle is manufactured. In this case, the manufacturing cost can be greatly reduced.

また、このテールゲート部の構造においては、カバー部材１９の取付ベース部２１の表面側に、ロアガーニッシュ１１の裏面を支持する弾性部材２７が取り付けられているため、テールゲート２の閉操作時等に加わる衝撃や振動をこの弾性部材２７によって吸収することができるとともに、ロアガーニッシュ１１の変形等も同時に防止することができる。したがって、ロアガーニッシュ１１のガタつきと変形を防止できることから、車両の商品性をより高めることができる。   In the structure of the tailgate portion, the elastic member 27 that supports the back surface of the lower garnish 11 is attached to the front surface side of the attachment base portion 21 of the cover member 19. The elastic member 27 can absorb shocks and vibrations applied to the lower garnish 11, and deformation of the lower garnish 11 can be prevented at the same time. Therefore, rattling and deformation of the lower garnish 11 can be prevented, and the merchantability of the vehicle can be further enhanced.
