Description

本発明は、樹脂製バックドアパネルを構成するインナーパネルにアウターパネルを取り付けるパネル取付構造に関する。 The present invention relates to a panel mounting structure for attaching an outer panel to an inner panel constituting a resin back door panel.

従来、バックドアを有する自動車等の車両において、バックドアは例えば図３に示すように構成されている。すなわち、図３に示すように、樹脂製のバックドア３０は、ウィンド開口３１ａを有する樹脂製のインナーパネル３１と、インナーパネル３１のウィンド開口３１ａを挟んで上下に分割され上パネル部材３２ａおよび下パネル部材３２ｂを有する樹脂製のアウターパネル３２と、ガラス製のウィンドパネル３３とを備えている（特許文献１参照）。 Conventionally, in a vehicle such as an automobile having a back door, the back door is configured as shown in FIG. 3, for example. That is, as shown in FIG. 3, the resin back door 30 is divided up and down with the resin inner panel 31 having the window opening 31 a and the window opening 31 a of the inner panel 31, and the upper panel member 32 a and the lower The resin-made outer panel 32 which has the panel member 32b, and the glass-made window panel 33 are provided (refer patent document 1).

そして、インナーパネル３１のウィンド開口３１ａの上部および下部それぞれに、アウターパネル３２の上パネル部材３２ａおよび下パネル部材３２ｂが接着されて取り付けられるとともに、アウターパネル３２の上パネル部材３２ａの下端縁部、下パネル部材３２ｂの上端縁部、インナーパネル３１のウィンド開口３１ａの周縁にウィンドパネル３３が重ねられた状態で接着されて取り付けられる。 The upper panel member 32a and the lower panel member 32b of the outer panel 32 are adhered and attached to the upper and lower portions of the window opening 31a of the inner panel 31, respectively, and the lower edge of the upper panel member 32a of the outer panel 32; The window panel 33 is adhered and attached to the upper end edge of the lower panel member 32 b and the periphery of the window opening 31 a of the inner panel 31 in a state of being overlapped.

この場合、特にアウターパネル３２の上パネル部材３２ａをインナーパネル３１に取り付けるときに、図４に示すように、インナーパネル３１の上端部の棚部３１ｂに粘性を有する予め接着剤３５を塗布しておき、図５に示すように、インナーパネル３１のウィンド開口３１ａのフランジ３１ｃの上部に、上パネル部材３２ａの下端に形成された基準ピン３６を当接させ、この当接した基準ピン３６を支点にして上パネル部材３２ａの上端部をインナーパネル３１に向けて回転させて上パネル部材３２ａの上端部をインナーパネル３１の上端部の棚部３１ｂに重ね、接着剤３５により上パネル部材３２ａをインナーパネル３１に取り付けている。 In this case, particularly when the upper panel member 32a of the outer panel 32 is attached to the inner panel 31, the adhesive 35 is applied in advance to the shelf 31b at the upper end of the inner panel 31 as shown in FIG. 5, the reference pin 36 formed at the lower end of the upper panel member 32a is brought into contact with the upper portion of the flange 31c of the window opening 31a of the inner panel 31 as shown in FIG. Then, the upper end of the upper panel member 32a is rotated toward the inner panel 31, and the upper end of the upper panel member 32a is overlapped with the shelf 31b of the upper end of the inner panel 31. It is attached to the panel 31.

しかし、上記した従来のパネル取付構造では、基準ピン３６を支点にして上パネル部材３２ａの上端を回転させていくと、樹脂製の上パネル部材３２ａの撓みによってその上端部が容易に変形するため、上パネル部材３２ａの上端部がインナーパネル３１の棚部３１ｂに当接して摺動し、そのまま上パネル部材３２ａを回転させていくと、棚部３１ｂに塗布した接着剤３５が上パネル部材３２ａの上端により掻き取られて接着剤３５が棚部３１ｂからなくなり、あるいは、接着剤35が棚部３１ｂからこぼれ落ちたりして、上パネル部材３２ａをインナーパネル３１に接着できなくなってしまうという問題がある。 However, in the above-described conventional panel mounting structure, when the upper end of the upper panel member 32a is rotated with the reference pin 36 as the fulcrum, the upper end portion is easily deformed by the bending of the resin upper panel member 32a. When the upper end portion of the upper panel member 32a abuts and slides on the shelf portion 31b of the inner panel 31, and the upper panel member 32a is rotated as it is, the adhesive 35 applied to the shelf portion 31b is the upper panel member 32a There is a problem that the adhesive 35 is removed from the shelf 31b by being scraped off by the upper end of the upper surface, or the adhesive 35 spills out from the shelf 31b and the upper panel member 32a can not be adhered to the inner panel 31 .

本発明は、樹脂製バックドアパネルを構成するインナーパネルにアウターパネルを簡単かつ確実に取り付けられるようにすることを目的とする。 An object of the present invention is to allow an outer panel to be easily and reliably attached to an inner panel constituting a resin back door panel.

上記した目的を達成するために、本発明のパネル取付構造は、樹脂製バックドアパネルを構成するインナーパネルにアウターパネルを取り付けるパネル取付構造において、前記インナーパネルは、その外周に設けられ前記アウターパネルの上端部が接着される棚部と、前記棚部の後端から下方に折曲して形成された折曲部と、前記折曲部の上端位置から後方に延びて形成された突起とを備え、前記アウターパネルの下部には、前記インナーパネルに当接して前記上端部を回転する際の支点が形成され、前記アウターパネルの取り付けの際に、前記アウターパネルの前記支点を回転中心として、前記上端部の内面が前記突起の先端にガイドされつつ前記上端部が前記インナーパネルの前記棚部に向かって回転し、前記上端部、前記棚部の後端部分および前記突起により囲まれる領域に貯留された接着剤により前記上端部が前記棚部に接着されることを特徴としている。 In order to achieve the above object, the panel mounting structure of the present invention is a panel mounting structure in which an outer panel is attached to an inner panel constituting a resin back door panel, wherein the inner panel is provided on the outer periphery of the outer panel. a ledge that the upper end portion is adhered, and the bent portions formed by bending downwardly from a rear end of the shelf, and a protrusion formed to extend rearward from the upper end position of the bent portion A fulcrum is formed at a lower portion of the outer panel in contact with the inner panel to rotate the upper end, and the fulcrum of the outer panel is set as a rotation center when the outer panel is attached . wherein the upper portion while the inner surface of the upper end portion is guided to the tip of the protrusion is rotated toward the ledge of the inner panel, the upper end, a rear end portion of the shelf And wherein said upper portion by an adhesive which is stored in a region surrounded by the projection is characterized in that it is bonded to the ledge.

係る構成によれば、アウターパネルの上端部が接着されるインナーパネルの棚部の後端に折曲部が形成され、この折曲部の上端位置から後方に延びるように突起が形成され、アウターパネルの接着される上端部、棚部の後端部分および突起により囲まれる領域に接着剤が貯留されるため、アウターパネルをインナーパネルに接着する際に、例えばアウターパネルの接着される上端部側を、インナーパネルに当接した支点を回転中心としてインナーパネルに向かって回転させたときに、アウターパネルの上端部がインナーパネルの突起の先端に当接してガイドされることから、従来のようにアウターパネルの上端部がインナーパネルの棚部を摺接して棚部に塗布された接着剤を掻き取るおそれがなく、しかも突起によって接着剤が堰き止められて棚部からこぼれ落ちたりするおそれもない。 With such a configuration, on the end portion of the A Utapaneru is bent portion is formed at the rear of the shelf portion of the inner panel to be bonded, protrusions are formed so as to extend rearward from the upper end position of the bent portion, on the end portion to be bonded of the outer panel, since the adhesive agent in a region surrounded by the rear end portion and the projecting ledge is stored, when bonding the outer panel to the inner panel, for example, on the adhesion of the outer panel the end portion side, when rotating toward the inner panel abuts the fulcrum to the inner panel as the center of rotation, since the top end portion of the outer panel are in contact with the guide at the tip of the inner panel projections, on the end portion of the conventional outer panel as without the risk of scraping the adhesive applied to the shelf portion in sliding contact with the ledge of the inner panel, yet adhesive dammed by the projection There is no risk of or spilled from the ledge.

本発明によれば、アウターパネルをインナーパネルに接着する際に、アウターパネルがインナーパネルの棚部に塗布された接着剤を掻き取ったり、接着剤が棚部からこぼれ落ちたりしてしまうことを未然に防止でき、樹脂製バックドアパネルを構成するインナーパネルにアウターパネルを簡単かつ確実に取り付けることが可能になる。 According to the present invention, when bonding the outer panel to the inner panel, the outer panel scrapes off the adhesive applied to the shelf of the inner panel or the adhesive spills from the shelf. This makes it possible to easily and reliably attach the outer panel to the inner panel constituting the resin back door panel.

本発明に係るパネル取付構造の一実施形態について、図１および図２を参照して詳細に説明する。ここで、本実施形態でいう前後、左右とはシートに着座した状態で見た前後、左右を意味する。なお、以下の説明では図３も参照する。 One embodiment of a panel mounting structure according to the present invention will be described in detail with reference to FIGS. 1 and 2. Here, in the present embodiment, front and rear, right and left mean front, rear, left and right as viewed in a state of being seated on a seat. In the following description, FIG. 3 is also referred to.

本実施形態における車両のバックドアは、図１に示すように、図３のインナーパネル３１と同様の樹脂製のインナーパネル１、および、このインナーパネル１に取り付けられる図３のアウターパネル３２と同様の樹脂製のアウターパネル２とを備える。ここで、アウターパネル２は、インナーパネル１のウィンド開口（図示せず）を挟んで配設される上パネル部材２ａおよび下パネル部材（図示せず）に分割されており、図１、図２には、アウターパネル２の上パネル部材２ａのみが図示されている。 The back door of the vehicle in this embodiment is, as shown in FIG. 1, similar to the resin inner panel 1 similar to the inner panel 31 of FIG. 3 and the outer panel 32 of FIG. 3 attached to the inner panel 1. And an outer panel 2 made of resin. Here, the outer panel 2 is divided into an upper panel member 2a and a lower panel member (not shown) disposed so as to sandwich a window opening (not shown) of the inner panel 1, as shown in FIGS. In the figure, only the upper panel member 2a of the outer panel 2 is illustrated.

そして、インナーパネル１は、その上端部外周に設けられアウターパネル２の上パネル部材２ａ上端部内周が接着される棚部１ａと、この棚部１ａの後端から下方に折曲して形成された折曲部１ｂと、折曲部１ｂの上端位置から後方に延びかつ車幅方向にわたって形成された突起１ｃと、ウィンド開口の周縁のフランジ１ｄとを備えている。一方、アウターパネル２の上パネル部材２ａの下端には基準ピン３が一体的に形成され、インナーパネル１のウィンド開口のフランジ１ｄの上部に、上パネル部材２ａの下端の基準ピン３が当接された状態で、図２に示すように、基準ピン３を支点にして上パネル部材２ａの上端部がインナーパネル１の棚部１ａに向けて回転され、上パネル部材２ａの上端部がインナーパネル１の棚部１ａに重ねられる。 The inner panel 1 is formed by bending downward from the rear end of the shelf 1a and the shelf 1a provided on the outer periphery of the upper end and to which the upper periphery of the upper panel 2a of the outer panel 2 is adhered. A bent portion 1b, a protrusion 1c extending rearward from the upper end position of the bent portion 1b and formed in the vehicle width direction, and a flange 1d at the periphery of the window opening are provided. On the other hand, the reference pin 3 is integrally formed at the lower end of the upper panel member 2a of the outer panel 2, and the reference pin 3 at the lower end of the upper panel member 2a is in contact with the upper portion of the flange 1d of the window opening of the inner panel 1. In the closed state, as shown in FIG. 2, the upper end of the upper panel member 2a is rotated toward the shelf 1a of the inner panel 1 with the reference pin 3 as a fulcrum, and the upper end of the upper panel member 2a is the inner panel 1 is stacked on the shelf 1a.

このとき、図２に示すように、インナーパネル１の棚部１ａの後端部分、アウターパネル２の上パネル部材２ａの上端部および突起１ｃにより囲まれる領域に、粘性を有する接着剤５が予め塗布されて貯留されており、上パネル部材２ａの上端部がインナーパネル１の棚部１ａに重ねられることによって、接着剤５が広がってインナーパネル１の棚部１ａにアウターパネル２の上パネル部材２ａの上端部が接着され、アウターパネル２の上パネル部材２ａがインナーパネル１に取り付けられる。 At this time, as shown in FIG. 2, the adhesive 5 having viscosity is previously formed in the area surrounded by the rear end portion of the shelf 1a of the inner panel 1, the upper end of the upper panel 2a of the outer panel 2, and the projection 1c. The adhesive 5 spreads when the upper end portion of the upper panel member 2 a is stacked on the shelf portion 1 a of the inner panel 1, and the upper panel member of the outer panel 2 is spread on the shelf portion 1 a of the inner panel 1. The upper end portion 2 a is adhered, and the upper panel member 2 a of the outer panel 2 is attached to the inner panel 1.

このように、アウターパネル２の上パネル部材２ａをインナーパネル１に接着する際に、上パネル部材２ａの基準ピン３を支点として上端部をインナーパネル１の棚部１ａに向かって回転させたときに、図２に示すように、上パネル部材２ａの上端部内周がインナーパネル１の突起１ｃの先端に当接してガイドされるため、上パネル部材２ａを更に回転させても上パネル部材２ａの上端がインナーパネル１の棚部１ａに接触せず、従来のように上パネル部材２ａの上端部がインナーパネル１の棚部１ａを摺接して棚部１ａに塗布された接着剤５を掻き取ることがなく、しかも突起１ｃによって接着剤５が堰き止められて棚部１ａからのこぼれ落ちが防止され、突起１ｃの先端によりガイドされつつ上パネル部材２ａが棚部１ａに向かって移動すると、棚部１ａの後端部分に貯留された接着剤５が、上パネル部材２ａの上端部内周により棚部１ａの全体にわたって均一に広げられることになる。 Thus, when the upper panel member 2a of the outer panel 2 is adhered to the inner panel 1, the upper end is rotated toward the shelf 1a of the inner panel 1 with the reference pin 3 of the upper panel member 2a as a fulcrum. As shown in FIG. 2, since the inner periphery of the upper end portion of the upper panel member 2a is abutted against and guided by the tip of the projection 1c of the inner panel 1, even if the upper panel member 2a is further rotated, the upper panel member 2a is The upper end does not contact the shelf 1a of the inner panel 1, and the upper end of the upper panel member 2a slides on the shelf 1a of the inner panel 1 to scrape off the adhesive 5 applied to the shelf 1a as in the prior art In addition, the adhesive 5 is blocked by the projection 1c to prevent spillage from the shelf 1a, and the upper panel member 2a moves toward the shelf 1a while being guided by the tip of the projection 1c. That the, the adhesive 5 which is stored in the rear portion of the shelf unit 1a, so that is evenly spread throughout the ledge 1a by the upper end inner periphery of the upper panel member 2a.

したがって、上記した実施形態によれば、アウターパネル２の上パネル部材２ａをインナーパネル１に接着する際に、上パネル部材２ａがインナーパネル１の棚部１ａに塗布された接着剤５を掻き取ったり、接着剤５が棚部１ａからこぼれ落ちたりしてしまうことを未然に防止することができ、樹脂製バックドアパネルを構成する樹脂製のインナーパネル１に樹脂製のアウターパネル２の上パネル部材２ａを簡単かつ確実に取り付けることができる。 Therefore, according to the above-described embodiment, when the upper panel member 2 a of the outer panel 2 is adhered to the inner panel 1, the upper panel member 2 a scrapes off the adhesive 5 applied to the shelf portion 1 a of the inner panel 1. And the adhesive 5 can be prevented in advance from falling from the shelf 1a, and the resin inner panel 1 constituting the resin back door panel is the upper panel member 2a of the resin outer panel 2 Can be attached easily and securely.

また、インナーパネル１の棚部１ａの後端から下方に折曲して形成された折曲部１ｂの上端位置から後方に延びて突起１ｃを形成したため、上パネル部材２ａの上端部を基準ピン３を支点としてインナーパネル１の棚部１ａに向かって回転させたときに、上パネル部材２ａの等端部の内周が突起１ｃの先端に当接し、これにより上パネル部材２ａの回転する上端部内周をガイドすることができ、上パネル部材２ａの上端が従来のようにインナーパネル１の棚部１ａに接触することを確実に防止しつつ、上パネル部材２ａの上端部をガイドしてインナーパネル１の棚部１ａに重ねることができる。 Further, since the protrusion 1c is formed extending backward from the upper end position of the bent portion 1b formed by bending downward from the rear end of the shelf portion 1a of the inner panel 1, the upper end portion of the upper panel member 2a is a reference pin When rotating toward the shelf 1a of the inner panel 1 with 3 as a fulcrum, the inner periphery of the equal end of the upper panel member 2a abuts on the tip of the projection 1c, thereby rotating the upper end of the upper panel 2a. The inner periphery of the portion can be guided, and the upper end portion of the upper panel member 2a is guided while the inner end of the upper panel member 2a is reliably prevented from contacting the shelf portion 1a of the inner panel 1 as in the prior art. It can be stacked on the shelf 1 a of the panel 1.

なお、本発明は上記した実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行なうことが可能である。 The present invention is not limited to the embodiment described above, and various modifications can be made other than the above without departing from the scope of the invention.

例えば、上記した実施形態では、インナーパネル１に突起１ｃを、車幅方向にわたって形成した場合について説明したが、車幅方向の複数箇所に突起１ｃを形成してもよい。 For example, in the above-described embodiment, although the case where the projections 1c are formed on the inner panel 1 in the vehicle width direction has been described, the projections 1c may be formed at a plurality of locations in the vehicle width direction.

また、上記した実施形態では、インナーパネル１の上端部外周に棚部１ａを形成し、アウターパネル２の上パネル部材２ａの上端部を棚部１ａに接着する例を示したが、棚部１ａの形成場所は、インナーパネル１の上端部に限らず、外周であればどこに形成されてもよい。 In the embodiment described above, the shelf 1a is formed on the outer periphery of the upper end of the inner panel 1, and the upper end of the upper panel member 2a of the outer panel 2 is adhered to the shelf 1a. The formation location of the may be formed not only at the upper end portion of the inner panel 1 but anywhere on the outer periphery.

また、上記した実施形態では、アウターパネル２の上下２分割された上パネル部材２ａを接着する場合について説明したが、アウターパネル２は必ずしも上下に分割されていなくてもよい。さらに、アウターパネル２の上下２分割された下パネル部材についても、同様にインナーパネル１に接着して取り付けることができるのはいうまでもない。 Moreover, although the above-mentioned embodiment demonstrated the case where the upper panel member 2a divided into the upper and lower sides 2 of the outer panel 2 was adhere | attached, the outer panel 2 does not necessarily need to be divided | segmented up and down. Furthermore, it goes without saying that the lower panel members which are divided into upper and lower parts of the outer panel 2 can be similarly adhered and attached to the inner panel 1.
