まず、第１実施形態に係る車両用樹脂バックドア構造１０について説明する。図１に示されるように、樹脂バックドア１２の上部側には、バックウインドウガラス１８が設けられる開口部１４が形成されている。そして、この樹脂バックドア１２は、図２に示されるように、互いに接合されることで閉断面形状を構成するとともに、開口部１４の少なくとも左右両側部１６（図１参照）を構成するインナパネル２０と、開口部１４全体を構成するアウタパネル３０と、を有している。 <First Embodiment>
First, the resin back door structure 10 for vehicles which concerns on 1st Embodiment is demonstrated. As shown in FIG. 1, an opening 14 in which a back window glass 18 is provided is formed on the upper side of the resin back door 12. As shown in FIG. 2, the resin back door 12 is joined to each other to form a closed cross-sectional shape, and at least the left and right side portions 16 (see FIG. 1) of the opening 14. 20 and an outer panel 30 constituting the entire opening 14.

なお、ここで言う左右両側部１６には、図１に示されるように、各側部１６から上下それぞれのコーナー部１６Ａ、１６Ｂの終わり（車幅方向内側の直線状に形成された部位と各コーナー部１６Ａ、１６Ｂの円弧状に形成された部位の境界部分であり、仮想直線Ｋで示された各位置）までが含まれる。   As shown in FIG. 1, the left and right side portions 16 referred to here are the ends of the corner portions 16 </ b> A and 16 </ b> B from the respective side portions 16 (the portions formed linearly on the inner side in the vehicle width direction and the respective portions). It is a boundary part of the part formed in the circular arc shape of corner part 16A, 16B, and each position shown by the virtual straight line K) is included.

また、インナパネル２０及びアウタパネル３０は、それぞれＰＣ／ＡＢＳ等の樹脂材で成形されている。更に、図２では、樹脂バックドア１２が閉じられた状態が示されており、車両本体４０側に取り付けられたウエザーストリップ３８がインナパネル２０の底壁（シール壁）２２に圧接されて弾性変形した状態が示されている。   Further, the inner panel 20 and the outer panel 30 are each formed of a resin material such as PC / ABS. Further, FIG. 2 shows a state in which the resin back door 12 is closed, and a weather strip 38 attached to the vehicle body 40 side is pressed against the bottom wall (seal wall) 22 of the inner panel 20 and elastically deformed. The state is shown.

図２に示されるように、インナパネル２０は、底壁２２の車幅方向外側端部からバックウインドウガラス１８へ向かって所定の角度で立ち上がる平板状の外側壁２４と、底壁２２の車幅方向内側端部からバックウインドウガラス１８へ向かって略垂直に立ち上がる平板状の縦壁部としての内側壁２８と、を有しており、断面略「Ｕ」字状に形成されている。   As shown in FIG. 2, the inner panel 20 includes a flat outer wall 24 that rises at a predetermined angle from the outer end in the vehicle width direction of the bottom wall 22 toward the back window glass 18, and the vehicle width of the bottom wall 22. And an inner wall 28 as a flat vertical wall portion that rises substantially vertically from the inner end of the direction toward the back window glass 18 and has a substantially “U” -shaped cross section.

外側壁２４の上端部（インナパネル２０の車幅方向外側端部）には、車幅方向外側へ張り出すフランジ部２６が一体に形成されている。そして、そのフランジ部２６の車幅方向外側端部には、バックウインドウガラス１８へ向かって延在するように屈曲された屈曲部２７が一体に形成されており、その先端部２７Ａは、バックウインドウガラス１８の内面（下面）１８Ａに近接配置されている。   A flange portion 26 that projects outward in the vehicle width direction is integrally formed at the upper end portion of the outer wall 24 (the outer end portion in the vehicle width direction of the inner panel 20). A bent portion 27 that is bent so as to extend toward the back window glass 18 is integrally formed at the outer end of the flange portion 26 in the vehicle width direction. The glass 18 is disposed close to the inner surface (lower surface) 18A.

インナパネル２０の車幅方向内側端部に形成された内側壁２８は、バックウインドウガラス１８に向かって延在されており、その上端部（先端部）２８Ａは、バックウインドウガラス１８の内面１８Ａに近接配置されている。つまり、内側壁２８の上端部２８Ａには、車幅方向内側へ張り出すフランジ部が形成されておらず、その上端部２８Ａは、バックウインドウガラス１８に対して交差する方向に延びている。   An inner side wall 28 formed at the inner end in the vehicle width direction of the inner panel 20 extends toward the back window glass 18, and an upper end portion (tip end portion) 28 </ b> A thereof is formed on the inner surface 18 </ b> A of the back window glass 18. Closely arranged. That is, a flange portion that protrudes inward in the vehicle width direction is not formed on the upper end portion 28 </ b> A of the inner wall 28, and the upper end portion 28 </ b> A extends in a direction intersecting the back window glass 18.

アウタパネル３０は、バックウインドウガラス１８に沿った略平板状（曲率の小さい曲面状）に形成されており、その車幅方向外側端部３２における上面（一方の面）３２Ａが、バックウインドウガラス１８の内面１８Ａに接着剤Ｇによって接合されている。そして、アウタパネル３０の車幅方向外側端部３２における下面（他方の面）３２Ｂが、インナパネル２０のフランジ部２６の上面２６Ａに接着剤Ｇによって接合されている。   The outer panel 30 is formed in a substantially flat plate shape (curved surface shape with a small curvature) along the back window glass 18, and an upper surface (one surface) 32 </ b> A of the outer end 32 in the vehicle width direction is formed on the back window glass 18. It is joined to the inner surface 18A by an adhesive G. The lower surface (the other surface) 32B of the outer panel 30 in the vehicle width direction outer side end portion 32B is joined to the upper surface 26A of the flange portion 26 of the inner panel 20 by an adhesive G.

アウタパネル３０の車幅方向内側端部には、車体下方側へ向かって屈曲された屈曲部３４が形成されており、その屈曲部３４の車幅方向内側を向く壁面３４Ａが、インナパネル２０の内側壁２８（上端部２８Ａ）の車幅方向外側を向く壁面２８Ｂに接着剤Ｇによって接合されている。   A bent portion 34 that is bent toward the vehicle body lower side is formed at the inner end in the vehicle width direction of the outer panel 30, and a wall surface 34 </ b> A that faces the inner side in the vehicle width of the bent portion 34 is the inner side of the inner panel 20. An adhesive G is joined to a wall surface 28B facing the vehicle width direction outer side of the wall 28 (upper end portion 28A).

これにより、インナパネル２０の開口側がアウタパネル３０によって閉塞され、インナパネル２０とアウタパネル３０とで閉断面形状が構成されるようになっている。なお、インナパネル２０とアウタパネル３０とで構成される閉断面内には、各種配線（図示省略）が収容されるようになっている。   Thereby, the opening side of the inner panel 20 is closed by the outer panel 30, and the inner panel 20 and the outer panel 30 form a closed cross-sectional shape. Various wirings (not shown) are accommodated in a closed cross section constituted by the inner panel 20 and the outer panel 30.

以上のような構成の第１実施形態に係る車両用樹脂バックドア構造１０において、次にその作用について説明する。   Next, the operation of the vehicular resin back door structure 10 according to the first embodiment having the above-described configuration will be described.

図２に示されるように、インナパネル２０の車幅方向内側端部に形成された内側壁２８の上端部２８Ａは、車幅方向内側へ張り出すことなく、バックウインドウガラス１８の内面１８Ａに近接配置されている。そして、アウタパネル３０の車幅方向内側端部に形成された屈曲部３４の壁面３４Ａは、その内側壁２８（上端部２８Ａ）の壁面２８Ｂに接合されて、車幅方向内側へ突出されない構成になっている。   As shown in FIG. 2, the upper end portion 28A of the inner wall 28 formed at the inner end portion in the vehicle width direction of the inner panel 20 is close to the inner surface 18A of the back window glass 18 without projecting inward in the vehicle width direction. Has been placed. And the wall surface 34A of the bending part 34 formed in the vehicle width direction inner side edge part of the outer panel 30 is joined to the wall surface 28B of the inner side wall 28 (upper end part 28A), and becomes a structure which does not protrude inside the vehicle width direction. ing.

したがって、インナパネル２０の内側壁２８の上端部２８Ａに、アウタパネル３０の車幅方向内側端部を接合するための車幅方向内側へ張り出すフランジ部（図示省略）が形成される構成に比べて、開口部１４の車幅方向内側を遮る領域を低減させることができ、開口部１４の左右両側部１６を細く形成することができる。よって、車室内からの車両後方の視界を改善することができる。   Therefore, a flange portion (not shown) that protrudes inward in the vehicle width direction for joining the inner end portion in the vehicle width direction of the outer panel 30 is formed on the upper end portion 28A of the inner wall 28 of the inner panel 20. The area | region which interrupts the vehicle width direction inner side of the opening part 14 can be reduced, and the right-and-left both sides 16 of the opening part 14 can be formed thinly. Therefore, the field of view behind the vehicle from the passenger compartment can be improved.

しかも、この閉断面形状は、上下それぞれのコーナー部１６Ａ、１６Ｂの終わり（仮想直線Ｋで示された各位置）までを含んで形成されているため、その閉断面内にリインフォースメントが設けられていなくても、左右両側部１６の剛性を確保することができる。よって、閉断面内にリインフォースメントが設けられる構成に比べて、部品点数を低減させることができ、車両の重量を低減させることができる。   In addition, since the closed cross-sectional shape is formed to include the ends of the upper and lower corner portions 16A and 16B (each position indicated by the virtual straight line K), the reinforcement is provided in the closed cross-section. Even if not, the rigidity of the left and right side portions 16 can be ensured. Therefore, the number of parts can be reduced and the weight of the vehicle can be reduced as compared with the configuration in which the reinforcement is provided in the closed section.

なお、アウタパネル３０の車幅方向内側端部（屈曲部３４）の形状は、図２に示されるものに限定されるものではなく、例えば図３に示されるように、車体上方側へ向かって屈曲された屈曲部３６とされてもよい。つまり、屈曲部３６の車幅方向内側を向く壁面３６Ａを内側壁２８の壁面２８Ｂに接着剤Ｇによって接合する構成にしてもよい。このような構成にしても、開口部１４の車幅方向内側を遮る領域を低減させることができ、開口部１４の左右両側部１６を細く形成することができる。   Note that the shape of the inner end portion (bent portion 34) in the vehicle width direction of the outer panel 30 is not limited to that shown in FIG. 2, but is bent toward the upper side of the vehicle body, for example, as shown in FIG. The bent portion 36 may be used. That is, the wall surface 36 </ b> A facing the inner side in the vehicle width direction of the bent portion 36 may be joined to the wall surface 28 </ b> B of the inner wall 28 by the adhesive G. Even if it is such a structure, the area | region which shields the vehicle width direction inner side of the opening part 14 can be reduced, and the both right and left side parts 16 of the opening part 14 can be formed thinly.

＜第２実施形態＞
次に、第２実施形態に係る車両用樹脂バックドア構造１０について説明する。なお、上記第１実施形態と同等の部位には同じ符号を付して詳細な説明（作用も含む）は、適宜省略する。 <Second Embodiment>
Next, the vehicle resin back door structure 10 according to the second embodiment will be described. In addition, the same code | symbol is attached | subjected to the site | part equivalent to the said 1st Embodiment, and detailed description (an effect | action is also included) is abbreviate | omitted suitably.

図４に示されるように、第２実施形態に係るインナパネル２０の内側壁２８は、その車体上方側への延在長さ（高さ）が、第１実施形態に係るインナパネル２０の内側壁２８よりも短く（低く）形成されている。詳細には、第２実施形態における内側壁２８の車体上方側への延在長さ（高さ）は、第１実施形態における内側壁２８の車体上方側への延在長さ（高さ）の半分以下とされている。   As shown in FIG. 4, the inner wall 28 of the inner panel 20 according to the second embodiment has an extension length (height) to the upper side of the vehicle body that is the inner side of the inner panel 20 according to the first embodiment. It is shorter (lower) than the wall 28. Specifically, the extension length (height) of the inner wall 28 to the vehicle body upper side in the second embodiment is the extension length (height) of the inner wall 28 to the vehicle body upper side in the first embodiment. Less than half.

第２実施形態に係るアウタパネル３０の車幅方向中途部は、インナパネル２０側（車体下方側）へ向けて所定の角度で折り曲げられており、その折り曲げられた車幅方向内側部分が傾斜壁３３とされている。そして、傾斜壁３３の車幅方向内側端部には、車体下方側へ向かって屈曲された屈曲部３４が形成されており、その屈曲部３４の壁面３４Ａが、内側壁２８の壁面２８Ｂに接着剤Ｇによって接合されている。   A midway portion in the vehicle width direction of the outer panel 30 according to the second embodiment is bent at a predetermined angle toward the inner panel 20 side (the vehicle body lower side), and the bent inner portion in the vehicle width direction is an inclined wall 33. It is said that. A bent portion 34 that is bent toward the vehicle body lower side is formed at the inner end in the vehicle width direction of the inclined wall 33, and the wall surface 34 </ b> A of the bent portion 34 is bonded to the wall surface 28 </ b> B of the inner wall 28. Bonded by the agent G.

なお、内側壁２８の車体上方側への延在長さ（高さ）は、屈曲部３４の車体下方側への延在長さ（高さ）と同一か、それよりも若干長く（高く）なる程度に形成されている。そして、この第２実施形態では、インナパネル２０とアウタパネル３０とで構成される閉断面形状が、上記第１実施形態に比べて小さくなっている（閉断面の面積が減少されている）。   The extension length (height) of the inner wall 28 to the upper side of the vehicle body is the same as or slightly longer (higher) than the extension length (height) of the bent portion 34 to the lower side of the vehicle body. It is formed to such an extent. And in this 2nd Embodiment, the closed cross-sectional shape comprised by the inner panel 20 and the outer panel 30 is small compared with the said 1st Embodiment (the area of a closed cross section is reduced).

換言すれば、この第２実施形態では、傾斜壁３３の上面３３Ａとバックウインドウガラス１８の内面１８Ａとの間に空間Ｓが確保されるようになっている。したがって、開口部１４の車幅方向内側を遮る領域を更に低減させることができ、開口部１４の左右両側部１６を更に細く形成することができる。よって、車室内からの車両後方の視界をより一層改善することができる。   In other words, in the second embodiment, a space S is secured between the upper surface 33A of the inclined wall 33 and the inner surface 18A of the back window glass 18. Accordingly, it is possible to further reduce the region that blocks the inside of the opening 14 in the vehicle width direction, and to further narrow the left and right side portions 16 of the opening 14. Therefore, the field of view behind the vehicle from the passenger compartment can be further improved.

なお、アウタパネル３０の車幅方向中途部をインナパネル２０側（車体下方側）へ折り曲げて傾斜壁３３を形成するのではなく、例えば図５に示されるように、インナパネル２０の内側壁２８の車体上下方向中途部を車幅方向外側へ所定の角度で折り曲げて傾斜壁２９を形成し、その傾斜壁２９の上端部（先端部）２９Ａをバックウインドウガラス１８の内面１８Ａに近接配置させるようにしてもよい。   In addition, the middle part of the outer panel 30 in the vehicle width direction is not bent to the inner panel 20 side (the vehicle body lower side) to form the inclined wall 33. For example, as shown in FIG. 5, the inner wall 28 of the inner panel 20 A slant wall 29 is formed by bending the vehicle body vertical middle part at a predetermined angle outward in the vehicle width direction, and an upper end portion (tip end portion) 29A of the slant wall 29 is disposed close to the inner surface 18A of the back window glass 18. May be.

つまり、傾斜壁２９（内側壁２８）の延在方向が、バックウインドウガラス１８と略直交する方向となるようにし、その傾斜壁２９（上端部２９Ａ）の車幅方向外側を向く壁面２９Ｂに、アウタパネル３０の車幅方向内側端部に形成された屈曲部３４の壁面３４Ａを接着剤Ｇによって接合する構成にしてもよい。   That is, the extending direction of the inclined wall 29 (inner wall 28) is made to be a direction substantially orthogonal to the back window glass 18, and the inclined wall 29 (upper end portion 29A) faces the outer side in the vehicle width direction on the wall surface 29B. You may make it the structure which joins the wall surface 34A of the bending part 34 formed in the vehicle width direction inner side edge part of the outer panel 30 with the adhesive agent G. FIG.

このような構成にしても、インナパネル２０とアウタパネル３０とで構成される閉断面形状を、上記第１実施形態に比べて小さくすることができ（閉断面の面積を減少させることができ）、傾斜壁２９の上面２９Ｃとバックウインドウガラス１８の内面１８Ａとの間に空間Ｓを確保することができる。したがって、開口部１４の車幅方向内側を遮る領域を更に低減させることができ、開口部１４の左右両側部１６を更に細く形成することができる。   Even with such a configuration, the closed cross-sectional shape formed by the inner panel 20 and the outer panel 30 can be reduced as compared with the first embodiment (the area of the closed cross-section can be reduced), A space S can be secured between the upper surface 29 </ b> C of the inclined wall 29 and the inner surface 18 </ b> A of the back window glass 18. Accordingly, it is possible to further reduce the region that blocks the inside of the opening 14 in the vehicle width direction, and to further narrow the left and right side portions 16 of the opening 14.

また、この構成によれば、アウタパネル３０の車幅方向内側への延在長さを、上記第１実施形態に比べて短くすることができるので、アウタパネル３０の製造コストを低減させることができる利点がある。更に、この第２実施形態では、インナパネル２０とアウタパネル３０とで構成される閉断面形状が、上記第１実施形態よりも小型化されるので、上記第１実施形態の場合よりも軽量化できる利点がある。   Further, according to this configuration, the length of the outer panel 30 extending inward in the vehicle width direction can be shortened as compared with the first embodiment, so that the manufacturing cost of the outer panel 30 can be reduced. There is. Furthermore, in the second embodiment, the closed cross-sectional shape formed by the inner panel 20 and the outer panel 30 is made smaller than the first embodiment, so that it can be lighter than the first embodiment. There are advantages.

以上、本実施形態に係る車両用樹脂バックドア構造１０について、図面を基に説明したが、本実施形態に係る車両用樹脂バックドア構造１０は、図示のものに限定されるものではなく、本発明の要旨を逸脱しない範囲内において、適宜設計変更可能なものである。例えば、アウタパネル３０の屈曲部３４、３６が接合される内側壁２８の部位は、図示の部位に限定されるものではない。また、インナパネル２０は、開口部１４の左右両側部１６だけではなく、開口部１４の上部及び下部に設けられていてもよく、インナパネル２０とアウタパネル３０とで開口部１４全体が構成されるようにしてもよい。   As mentioned above, although the resin back door structure 10 for vehicles which concerns on this embodiment was demonstrated based on drawing, the resin back door structure 10 for vehicles which concerns on this embodiment is not limited to the thing of illustration, this book The design can be changed as appropriate without departing from the scope of the invention. For example, the portion of the inner wall 28 to which the bent portions 34 and 36 of the outer panel 30 are joined is not limited to the illustrated portion. Further, the inner panel 20 may be provided not only on the left and right side portions 16 of the opening 14 but also on the upper and lower portions of the opening 14. The inner panel 20 and the outer panel 30 constitute the entire opening 14. You may do it.
