Description

本発明は、車両の部材接合部の構造に関する。 The present invention relates to the structure of a member joint of a vehicle.

通常、車両は、金属材料により形成される部材、ガラスにより形成される部材、及び樹脂材料により形成される部材等、複数種の部材によって構成されている。このように異種の材料を有する車両では、互いに異なる材料で形成された部材を接合する必要がある。例えば、特許文献１には、金属製のヒンジリンフォースメントと、樹脂製のアッパアウタパネルと、樹脂製のインナパネルと、バックウィンドガラスとの接合について開示されている。 Usually, a vehicle is composed of a plurality of types of members such as a member formed of a metal material, a member formed of glass, and a member formed of a resin material. In a vehicle having different materials as described above, it is necessary to join members made of different materials to each other. For example, Patent Document 1 discloses a joining of a metal hinge reinforcement, a resin upper outer panel, a resin inner panel, and a back window glass.

この例では、金属製のヒンジリンフォースメントの表面に樹脂製のアッパアウタパネルが接着剤により接合され、ヒンジリンフォースメントの裏面に樹脂製のインナパネルが接着剤により接合され、３枚重ねの構造が開示されている。さらに、この例では、上記のアッパアウタパネルの表面にバックウィンドガラスが接着剤により接合され、アッパアウタパネルの裏面には、ヒンジリンフォースメントが接着剤により接合されている構造が開示されている。 In this example, a resin upper outer panel is bonded to the front surface of the metal hinge reinforcement with an adhesive, and a resin inner panel is bonded to the back surface of the hinge reinforcement with an adhesive to form a three-layer structure. Is disclosed. Further, in this example, a structure is disclosed in which the back wind glass is bonded to the surface of the upper outer panel with an adhesive, and the hinge reinforcement is bonded to the back surface of the upper outer panel with an adhesive.

通常、ポロプロプレン（ＰＰ）等の難接着材料の樹脂部品とガラス部材とを接着剤で接合するときに、樹脂部品と接着剤との接着界面と、接着剤とガラス部材との接着界面とでは、接着強度が異なる。このような場合で、さらに、接着剤自体は十分な強度があって、接着材が硬化して形成される接着層が破壊する可能性が低いときには、樹脂部品と接着剤との接着界面で、他の部分よりも剥がれる可能性が高くなる。 Normally, when a resin part of a difficult-to-adhere material such as poloproprene (PP) and a glass member are bonded with an adhesive, the adhesive interface between the resin part and the adhesive and the adhesive interface between the adhesive and the glass member are usually formed. Adhesive strength is different. In such a case, further, when the adhesive itself is strong enough and the adhesive layer formed by curing the adhesive is unlikely to break, at the adhesive interface between the resin part and the adhesive, It is more likely to come off than other parts.

上記例のような場合、各部材がそれぞれ別々の接着剤層で接合されているため、接着強度が弱い部品では、接着剤との接着界面で剥がれる可能性がある。接着界面で剥がれが発生したときには、部材が脱落する可能性もある。このため、異種材料を接着剤で接合する構造において、部材が脱落することを防止する上で、上記例のような構造には、改善の余地があった。 In the case of the above example, since each member is bonded by a separate adhesive layer, a part having a weak adhesive strength may be peeled off at the adhesive interface with the adhesive. When peeling occurs at the bonding interface, the member may fall off. Therefore, in the structure in which different materials are joined with an adhesive, there is room for improvement in the structure as in the above example in order to prevent the members from falling off.

本発明は上記課題を解決するためになされたものであって、その目的は、接着の難しい材料により形成された部品であっても、接着材層での剥がれを抑制しつつ、剥がれによる部材の脱落を防止することが可能な部材接合部の構造を提供することである。 The present invention has been made to solve the above problems, and an object of the present invention is to prevent peeling of a member due to peeling while suppressing peeling in an adhesive layer even for a part formed of a material that is difficult to bond. It is to provide the structure of the member joint part which can prevent it from falling off.

上記目的を達成するための本発明に係る車両の部材接合部の構造は、車体に取り付けられているインナ部材と、該インナ部材の車両外側に設置されるガラス部材とに、前記インナ部材と前記ガラス部材との間に配置された樹脂部品が接着剤により接合される。当該車両の部材接合部の構造において、前記部材接合部は、前記樹脂部材に設けられた第１接着部と、前記インナ部材に設けられた第２接着部と、を備え、前記第１接着部には、前記ガラス部材に対向し、前記接着剤が塗布される塗布面が設けられ、該塗布面には、貫通孔が設けられ、前記第１接着部は、前記塗布面と前記ガラス部材との間に設けられた第１空間部を有し、前記第２接着部は、前記貫通孔によって前記第１空間部に連通されている第２空間部を有しており、前記塗布面に塗布された前記接着剤が、前記第１空間部に充填され、且つ、前記貫通孔を介して前記第２空間部に充填されることによって、前記第１接着部は、前記第２接着部及び前記ガラス部材に接合される。 The structure of the member joint portion of the vehicle according to the present invention for achieving the above object is such that the inner member attached to the vehicle body and the glass member installed on the outside of the vehicle of the inner member are formed with the inner member and the inner member. The resin parts arranged between the glass members and the glass members are joined by an adhesive. In the structure of the member joint portion of the vehicle, the member joint portion includes a first adhesive portion provided on the resin member and a second adhesive portion provided on the inner member, and the first adhesive portion is provided. Is provided with a coating surface facing the glass member to which the adhesive is applied, a through hole is provided in the coating surface, and the first adhesive portion is formed by the coating surface and the glass member. The second adhesive portion has a second space portion that is communicated with the first space portion by the through hole, and is applied to the coated surface. The adhesive is filled in the first space portion and is filled in the second space portion through the through hole, so that the first adhesive portion is filled with the second adhesive portion and the said. It is joined to a glass member.

本発明によれば、接着の難しい材料により形成された部品であっても、接着材層での剥がれを抑制しつつ、剥がれによる部材の脱落を防止することができる。 According to the present invention, even if a part is made of a material that is difficult to adhere to, it is possible to prevent the member from falling off due to peeling while suppressing peeling in the adhesive layer.

The first adhesive portion 11 and the window glass 5 are joined by the adhesive filled in the first space portion 16. Further, the adhesive applied to the coated surface 15 passes through the through hole 14 and is filled in the second space portion 26. As a result, the front surface portion 12 of the first adhesive portion 11 and the second adhesive portion 23 are joined.

接着剤は、第１空間部１６、第２空間部２６及びこれらを繋ぐ貫通孔１４に充填された状態で硬化し、１つの接着層３０を形成している。当該接着層３０は、図７に示すように、第１空間部１６に形成される後側接着層３２と、第２空間部２６に形成される前側接着層３１と、貫通孔１４の内側に形成され、前側接着層３１及び後側接着層３２を接続する接続層３３と、を含み、これらが一体的に形成されている。 The adhesive is cured in a state of being filled in the first space portion 16, the second space portion 26, and the through hole 14 connecting them to form one adhesive layer 30. As shown in FIG. 7, the adhesive layer 30 is formed inside the rear adhesive layer 32 formed in the first space portion 16, the front adhesive layer 31 formed in the second space portion 26, and the through hole 14. It is formed and includes a connecting layer 33 that connects the front adhesive layer 31 and the rear adhesive layer 32, and these are integrally formed.

後側接着層３２及び前側接着層３１は、貫通孔１４の径方向外側まで広がっている。この例では、後側接着層３２は、貫通孔１４からその周辺の塗布面１５に広がっている状態で、接続層３３に一体的に形成され、塗布面１５及び窓ガラス５に接着されている。また、前側接着層３１は、貫通孔１４からその周辺の前面部１２に広がっている状態で、接続層３３に一体的に形成され、且つ第１接着部１１の前面部１２及び第２接着部２３に接着されている。 The rear adhesive layer 32 and the front adhesive layer 31 extend radially outward of the through hole 14. In this example, the rear adhesive layer 32 is integrally formed with the connecting layer 33 in a state of extending from the through hole 14 to the coating surface 15 around it, and is adhered to the coating surface 15 and the window glass 5. .. Further, the front adhesive layer 31 is integrally formed with the connection layer 33 in a state of extending from the through hole 14 to the front surface portion 12 around the through hole 14, and the front surface portion 12 and the second adhesive portion of the first adhesive portion 11 are formed. It is adhered to 23.

樹脂製のスポイラー１０の第１接着部１１と接着層３０との接着強度は、通常、板金製のフレーム部材２０と前側接着層３１との接着強度、及び、窓ガラス５と後側接着層３２との接着強度よりも低い。そのため、万が一、接着層３０が剥離する場合、第１接着部１１と接着層３０との接着界面で剥離する可能性が、他の接着界面に比べて高い。 The adhesive strength between the first adhesive portion 11 of the resin spoiler 10 and the adhesive layer 30 is usually the adhesive strength between the sheet metal frame member 20 and the front adhesive layer 31 and the adhesive strength between the window glass 5 and the rear adhesive layer 32. It is lower than the adhesive strength with. Therefore, in the unlikely event that the adhesive layer 30 is peeled off, there is a higher possibility that the adhesive layer 30 will be peeled off at the adhesive interface between the first adhesive portion 11 and the adhesive layer 30 as compared with other adhesive interfaces.

これに対して、本実施形態では、樹脂製の第１接着部１１と接着層３０との接着界面は、塗布面１５に加え、貫通孔１４の内壁及び第１接着部１１の前面部１２にも形成される。このため、接着界面が塗布面１５のみに形成される場合に比べて、接着界面の面積が大きくなる。これにより、接着強度が増大し、剥離を抑制することができる。 On the other hand, in the present embodiment, the adhesive interface between the resin-made first adhesive portion 11 and the adhesive layer 30 is formed on the inner wall of the through hole 14 and the front surface portion 12 of the first adhesive portion 11 in addition to the coating surface 15. Is also formed. Therefore, the area of the adhesive interface is larger than that in the case where the adhesive interface is formed only on the coated surface 15. As a result, the adhesive strength is increased and peeling can be suppressed.

第１接着部１１と接着層３０との接着界面が剥離する場合、詳細には、塗布面１５と後側接着層３２との接着界面における剥離、及び、前面部１２と前側接着層３１との接着界面における剥離が発生した場合において、後側接着層３２は、貫通孔１４の径方向外側まで広がっているので、後側接着層３２が前面部１２で係止された状態が保たれる。そのため、スポイラー１０がフレーム部材２０から脱落することを防止できる。 When the adhesive interface between the first adhesive portion 11 and the adhesive layer 30 is peeled off, in detail, the peeling at the adhesive interface between the coated surface 15 and the rear adhesive layer 32, and the peeling between the front surface portion 12 and the front adhesive layer 31 When peeling occurs at the adhesive interface, the rear adhesive layer 32 extends to the outside in the radial direction of the through hole 14, so that the rear adhesive layer 32 is kept locked by the front surface portion 12. Therefore, it is possible to prevent the spoiler 10 from falling off from the frame member 20.

本実施形態の第２接着部２３には、車両前方（車両内側方向）に凹む凹形状部２７が設けられており、第２空間部２６は、凹形状部２７の内側に設けられている。また、本実施形態では、第２接着部２３は、フレーム部材２０に設けられた取付孔２３Ｂに取り付けられたカップ状の中間部材２５を有している。凹形状部２７は、中間部材２５に設けられている。 The second adhesive portion 23 of the present embodiment is provided with a concave-shaped portion 27 recessed in the front of the vehicle (inward direction of the vehicle), and the second space portion 26 is provided inside the concave-shaped portion 27. Further, in the present embodiment, the second adhesive portion 23 has a cup-shaped intermediate member 25 attached to the attachment hole 23B provided in the frame member 20. The concave portion 27 is provided on the intermediate member 25.

取付孔２３Ｂは、第１接着部１１の前面部１２に対向するように、第２接着部２３の主面２３Ａに形成されており、第１接着部１１の貫通孔１４に、車両前方視で重なって配置されている。中間部材２５は、図６〜図８に示すように、底付の円筒状の部材で、軸方向の一方（車両後方側）の端部に開口を有している。本実施形態の凹形状部２７は、中間部材２５の開口と、中間部材２５の円筒の内側とにより構成されている。また、中間部材２５の開口縁には、径方向に張り出すフランジ（係止部）２５Ａが設けられている。すなわち、中間部材２５は、いわゆるハット形状である。 The mounting hole 23B is formed on the main surface 23A of the second adhesive portion 23 so as to face the front surface portion 12 of the first adhesive portion 11, and is formed in the through hole 14 of the first adhesive portion 11 when viewed from the front of the vehicle. They are placed on top of each other. As shown in FIGS. 6 to 8, the intermediate member 25 is a cylindrical member with a bottom and has an opening at one end (rear side of the vehicle) in the axial direction. The concave portion 27 of the present embodiment is composed of an opening of the intermediate member 25 and the inside of the cylinder of the intermediate member 25. Further, a flange (locking portion) 25A projecting in the radial direction is provided on the opening edge of the intermediate member 25. That is, the intermediate member 25 has a so-called hat shape.

また、取付孔２３Ｂの孔縁には、孔縁を止水するために、孔明き円板状のシール部材２４（スポンジ素材）が接着剤等により接合されており、フランジ２５Ａは、第２接着部２３の主面２３Ａのうち、取付孔２３Ｂの縁に位置する部分に、シール部材２４を介して、係止されている。さらに、フランジ２５Ａは、第１接着部１１の前面部１２に当接されている。本実施形態では、中間部材２５の開口付近に前側接着層３１が形成されるように、接着剤が充填される。 Further, a perforated disk-shaped sealing member 24 (sponge material) is bonded to the hole edge of the mounting hole 23B with an adhesive or the like in order to stop water from the hole edge, and the flange 25A is second-bonded. Of the main surface 23A of the portion 23, the portion located at the edge of the mounting hole 23B is locked via the seal member 24. Further, the flange 25A is in contact with the front surface portion 12 of the first adhesive portion 11. In the present embodiment, the adhesive is filled so that the front adhesive layer 31 is formed near the opening of the intermediate member 25.

凹形状部２７に接着剤が充填され、さらに、窓ガラス５に接着した接着剤が硬化して、前側接着層３１を形成することにより、接着層３０をアンカーとして機能させることができる。このため、接着が難しい部材、例えば、ＰＰ樹脂等であっても、接着剤の粘度によって、隙間が生じずに固定することが可能となる。また、接着層３０をアンカーとすることができるため、締結部品等の部品を増やす必要がなく、スポイラー１０の組付けも容易になる。 The concave portion 27 is filled with an adhesive, and the adhesive adhered to the window glass 5 is cured to form the front adhesive layer 31, so that the adhesive layer 30 can function as an anchor. Therefore, even a member that is difficult to bond, for example, PP resin or the like, can be fixed without forming a gap depending on the viscosity of the adhesive. Further, since the adhesive layer 30 can be used as an anchor, it is not necessary to increase the number of parts such as fastening parts, and the spoiler 10 can be easily assembled.

凹形状部２７を、フレーム部材２０とは別の部材とすることで、凹形状部２７の開口の面積を容易に変更することができる。その結果、第２空間部２６の容積の調整が容易になり、前側接着層３１との接着界面の面積の効率的な調整が可能となり、接着強度の調整を容易に行うことができる。 By making the concave portion 27 a member different from the frame member 20, the area of the opening of the concave portion 27 can be easily changed. As a result, the volume of the second space portion 26 can be easily adjusted, the area of the adhesive interface with the front adhesive layer 31 can be efficiently adjusted, and the adhesive strength can be easily adjusted.

フレーム部材２０に設けられた第３接着部２８は、窓ガラス５の前面に、接着剤により直接接合される。第３接着部２８は、車幅方向両側の第２接着部２３の間に設けられ、車幅方向に延びている。さらに、第３接着部２８の車幅方向両側部は、車両下方に湾曲し、車両下方に延びている。 The third adhesive portion 28 provided on the frame member 20 is directly bonded to the front surface of the window glass 5 with an adhesive. The third adhesive portion 28 is provided between the second adhesive portions 23 on both sides in the vehicle width direction and extends in the vehicle width direction. Further, both side portions of the third adhesive portion 28 in the vehicle width direction are curved downward in the vehicle and extend downward in the vehicle.

さらに、塗布面１５は、塗布面１５を周囲に位置する樹脂部品（後面部１３の主面１３Ａ）よりも、車両内側に位置している。このように凹部を設けることで、第１空間部１６の厚み（車両前後方向の寸法）や、接着界面の面積を大きくすることができる。これにより、第１接着部１１と窓ガラス５との接着強度を安定して確保することができる。 Further, the coated surface 15 is located inside the vehicle with respect to the resin component (main surface 13A of the rear surface portion 13) located around the coated surface 15. By providing the recess in this way, the thickness of the first space 16 (dimensions in the front-rear direction of the vehicle) and the area of the adhesive interface can be increased. As a result, the adhesive strength between the first adhesive portion 11 and the window glass 5 can be stably secured.
