Description
本発明は、車両のフロントボディの開口とフロントパネルと間隙を密閉するフロントパネルのシール構造に関する。
The present invention relates to a front panel sealing structure that seals a gap between a front panel opening and a front panel of a vehicle.
特許文献１には、フロントパネルとカウルアッパーとの境界部の隙間をウェザーストリップによってシールするシール構造が記載されている。ウェザーストリップはカウルアッパー側に装着され、フロントパネルを閉じると、フロントパネルの端部がウェザーストリップに当接して密着する。

The weather strip is mounted on the cowl upper side, and when the front panel is closed, the end of the front panel comes into contact with and closely contacts the weather strip.
一般に、フロントパネルとカウルアッパー（フロントボディ）との境界部はフロントパネルの前面（パネル前面）に比べて水が滞留し易く、境界部に位置するフロントパネルの端縁部はパネル前面に比べて錆び易い。
In general, the boundary between the front panel and the cowl upper (front body) tends to retain water compared to the front of the front panel (front of the panel), and the edge of the front panel located at the boundary is compared to the front of the panel. Easy to rust.
このため、特許文献１のようにシール部材（ウェザーストリップ）をフロントボディ側に装着する構造では、フロントパネルの端縁部に防錆のための特別な加工（例えば末端の切断面に発生するバリ等を研磨によって除去した後、端縁部の末端まで十分に塗装するなど）を施す必要があり、そのため、フロントパネルの製造工数が増大する。
For this reason, in a structure in which a seal member (weather strip) is mounted on the front body side as in Patent Document 1, special processing for rust prevention (for example, burrs generated on the cut surface of the end) is applied to the edge of the front panel. Etc. are removed by polishing, and it is necessary to sufficiently coat the end of the edge portion), which increases the man-hour for manufacturing the front panel.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a seal structure that can improve the rust prevention property of an edge portion without subjecting the edge portion of the front panel to special processing for rust prevention.
本発明のフロントパネルのシール構造は、フロントパネルと弾性シール材とを備える。フロントパネルは、車両の車幅方向に沿って配置されるパネル本体と、パネル本体の周縁の所定領域から後方へ曲折して延びるパネル縁部とを一体的に有し、車両のフロントボディに取付けられてフロントボディの開口を塞ぐ。弾性シール材は、装着部と板状の突出部とを一体的に有する。装着部は、シール外壁部とシール内壁部との間でパネル挿入溝が前方へ開口するＵ状断面であり、パネル縁部をパネル挿入溝へ前方から挿入することにより弾性変形してパネル縁部に保持される。突出部は、装着部がパネル縁部に保持されたシール装着状態で、シール外壁部から突出して上記所定領域に沿って延び、開口の縁面に密着する。
The seal structure of the front panel of the present invention includes a front panel and an elastic seal material. The front panel integrally has a panel main body arranged along the vehicle width direction of the vehicle and a panel edge that extends backward from a predetermined region on the periphery of the panel main body and is attached to the front body of the vehicle. To close the opening of the front body. The elastic sealing material integrally has a mounting portion and a plate-like protrusion. The mounting portion has a U-shaped cross-section in which the panel insertion groove opens forward between the seal outer wall portion and the seal inner wall portion, and is elastically deformed by inserting the panel edge portion into the panel insertion groove from the front, so that the panel edge portion Retained. The protruding portion protrudes from the outer wall portion of the seal and extends along the predetermined region in close contact with the edge surface of the opening in a state where the mounting portion is held on the edge of the panel.
シール装着状態で、シール外壁部とシール内壁部とは、上記所定領域の一端から他端に亘ってパネル縁部の外面と内面とにそれぞれ密着し、突出部は、シール外壁部側から突出先端側に向かって斜め前方へ傾斜し、弾性シール材は、突出部が開口の縁面に密着することにより開口とフロントパネルとの間を密閉する。突出部の板厚は、シール外壁部側が厚く突出先端側が薄くなるように、前記突出先端側に向かって徐々に先細りする。
The seal outer wall portion and the seal inner wall portion are in close contact with the outer surface and the inner surface of the panel edge portion from one end to the other end of the predetermined region in a state where the seal is mounted, and the protruding portion protrudes from the seal outer wall portion side. The elastic sealing material is inclined obliquely forward toward the side, and the protruding portion is in close contact with the edge surface of the opening to seal between the opening and the front panel. The plate thickness of the protruding portion is gradually tapered toward the protruding tip side so that the seal outer wall side is thick and the protruding tip side is thin.
上記構成では、シール装着状態において、パネル本体の周縁の所定領域の一端から他端に亘り、シール外壁部とシール内壁部とがパネル縁部の外面と内面とにそれぞれ密着した状態で、パネル縁部の末端が装着部によって確実に覆われる。そのため、パネル縁部に特別な加工を施すことなく、弾性シール材の装着部によってパネル縁部の防錆性を高めることができる。
In the above configuration, in a state where the seal is mounted, the panel outer edge and the inner seal wall are in close contact with the outer surface and the inner surface of the panel edge from one end to the other end of the predetermined region on the peripheral edge of the panel body. The end of the part is securely covered by the mounting part. Therefore, the rust prevention property of a panel edge part can be improved by the mounting part of an elastic sealing material, without giving a special process to a panel edge part.
また、突出部がシール外壁部側から突出先端側に向かって斜め前方へ傾斜するので、洗車時等にパネル縁部と開口との間隙に水が高圧で吹付けられた場合であっても、突出部によって水の浸入を確実に防止することができる。
In addition, since the projecting portion is inclined obliquely forward from the seal outer wall portion side toward the projecting tip side, even when water is sprayed at a high pressure in the gap between the panel edge and the opening at the time of car washing, The protrusion can reliably prevent water from entering.
さらに、突出部の板厚は、シール外壁部側が厚く突出先端側が薄くなるように、突出先端側に向かって徐々に先細りするので、突出部の板厚をシール外壁部側から突出先端部側まで略均等に形成する場合に比べて、突出部の弾性力（反発力）を、フロントパネルの取付作業性を損なうことなく、且つ長期間使用しても劣化によって防水性が低下し難い強度に設定し易い。従って、弾性シール材による防錆性を長期間維持させることができる。
Furthermore, the plate thickness of the protruding portion gradually tapers toward the protruding tip side so that the seal outer wall side is thick and the protruding tip side is thin, so the protruding plate thickness is from the seal outer wall side to the protruding tip side. Compared to the case where it is formed approximately evenly, the elastic force (repulsive force) of the protrusion is set to a strength that does not impair the workability of mounting the front panel and that does not easily deteriorate due to deterioration even after long-term use. Easy to do. Therefore, the antirust property by the elastic sealing material can be maintained for a long time.

Further, since the projecting portion 12 is inclined upward and obliquely forward toward the projecting tip 12a side, water is sprayed at a high pressure on the gap between the panel upper edge portion 7 and the opening 3 at the time of car washing or the like. However, the intrusion of water can be reliably prevented by the protrusion 12.
さらに、突出部１２の板厚は、シール外壁部１３側が厚く突出先端１２ａ側が薄くなるように、突出先端１２ａ側に向かって徐々に先細りするので、突出部の板厚をシール外壁部側から突出先端部側まで略均等に形成する場合に比べて、突出部１２の弾性力（反発力）を、フロントパネル４の取付作業性を損なうことなく、且つ長期間使用しても劣化によって防水性が低下し難い強さに設定し易い。従って、上シール材１０による防錆性を長期間維持させることができる。
Furthermore, the plate thickness of the protruding portion 12 gradually tapers toward the protruding tip 12a side so that the seal outer wall portion 13 side is thick and the protruding tip 12a side is thin, so the plate thickness of the protruding portion protrudes from the seal outer wall side. Compared to the case where the front end portion is formed substantially evenly, the elastic force (repulsive force) of the protruding portion 12 does not impair the mounting workability of the front panel 4 and is waterproof due to deterioration even when used for a long time. It is easy to set the strength to be difficult to decrease. Therefore, the antirust property by the upper sealing material 10 can be maintained for a long time.

例えば、本実施形態では、パネル本体６にパネル上縁部７を曲折形成し、このパネル上縁部７に上シール材１０を取付ける場合について説明したが、パネル本体６の周縁の他の領域（例えば側縁）に後方へ曲折して延びるパネル縁部を形成し、このパネル縁部に上シール材１０と同様の弾性シール材を取付けてもよい。
For example, in this embodiment, the case where the panel upper edge portion 7 is bent and formed in the panel main body 6 and the upper sealing material 10 is attached to the panel upper edge portion 7 has been described. For example, a panel edge portion that bends backward and extends at the side edge), and an elastic seal material similar to the upper seal material 10 may be attached to the panel edge portion.
