Description

  The present invention relates to a front panel seal structure that seals a gap between a front panel opening and a front panel of a vehicle.

  Patent Document 1 describes a seal structure in which a gap at a boundary portion between a front panel and a cowl upper is sealed with a weather strip. 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.

JP-A-11-348828

  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.

  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 number of manufacturing steps of the front panel.

  Then, this invention aims at provision of the seal structure which can improve the rust prevention property of an edge part, without giving the special process for rust prevention to the edge part of a front panel.

  In order to achieve the above object, a front panel seal structure of the present invention includes a front panel and an elastic seal material. The front panel integrally includes a panel body that stands up along the vehicle width direction, and a panel edge portion that bends and extends backward from a predetermined region on the periphery of the panel body, and is attached to the front body and attached to the front body. Close the opening. 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.

  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.

  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. Since the end of the part is surely covered by the mounting part, the rust prevention of the panel edge part can be enhanced by the mounting part of the elastic seal material without performing special processing on the panel edge part.

  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.

  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 protrusions does not impair the workability of mounting the front panel, and the strength that prevents waterproofing from being deteriorated due to deterioration even after long-term use. Easy to set. Therefore, the antirust property by the elastic sealing material can be maintained for a long time.

  ADVANTAGE OF THE INVENTION According to this invention, the antirust property of an edge part can be improved, without giving the special process for antirust to the edge part of a front panel.

  As shown in FIGS. 1 and 2, the front surface of the cab 1 of the vehicle includes a front body 2, a front panel 4, a radiator grill 5, and the like.

  The front body 2 is disposed along the vehicle width direction, and a substantially rectangular opening 3 is formed in the central portion of the front body 2.

  The front panel 4 has a rectangular panel main body 6 standing along the vehicle width direction, and a panel upper edge extending backward from a substantially entire area of the upper end edge of the panel main body 6 (a predetermined region on the periphery of the panel main body 6). Part (panel edge part) 7 and is disposed at a position to close the opening 3 of the front body 2. A center reinforcement (not shown) and a side drain force (not shown) are respectively fixed to a substantially central portion and left and right side portions of the rear surface of the front panel 4.

  The radiator grill 5 is attached to the front surface of the front body 2 below the front panel 4.

  The left and right fasteners (not shown) of the front body 2 are inserted into and engaged with the left and right fasteners (not shown) of the front panel 4, and the flange portion of the center reinforcement is engaged with the clip member (not shown) of the lower portion of the front body 2. The front panel 4 is attached to the front body 2 by sandwiching (not shown). In this mounted state, the panel upper edge portion 7 of the front panel 4 faces the edge surface 3a of the opening 3 of the front body 2 (see FIG. 3), and the front panel 4 closes the opening 3 of the front body 2 (FIG. 2). reference).

  As shown in FIGS. 3 and 4, the panel upper edge portion 7 of the front panel 4 is hermetically sealed over the substantially entire region in the left-right direction between the panel upper edge portion 7 and the edge surface 3 a of the opening 3. A rubber upper sealing material (elastic sealing material) 10 is attached. The upper seal material 10 is a long material having substantially the same cross section extending over substantially the entire region from the left end to the right end of the panel upper edge portion 7, and a mounting portion 11 mounted on the panel upper edge portion 7 and a mounting portion 11. And a plate-like projecting portion 12 projecting from the body. It should be noted that the left and right ends of the upper seal material 10 are attached to the left and right side edges 8 of the front panel 4 (panel body 6), and the space between the side edges 8 and the opening 3 is substantially the entire area in the vertical direction. A side sealing material (not shown) that is hermetically extended extends integrally.

  The mounting portion 11 has a U-shaped cross section integrally including a seal outer wall portion 13, a seal inner wall portion 14, and a bottom wall portion 15. The rear end portion of the seal outer wall portion 13 and the rear end portion of the seal inner wall portion 14 are connected by a bottom wall portion 15, and a panel insertion groove 16 opening forward is provided between the seal outer wall portion 13 and the seal inner wall portion 14. Is formed. By inserting the panel upper edge portion 7 into the panel insertion groove 16 from the front, the mounting portion 11 is elastically deformed and held by the panel upper edge portion 7.

  The protruding portion 12 protrudes from the seal outer wall portion 13 in the seal mounting state in which the mounting portion 11 is held by the panel upper edge portion 7, extends in the left-right direction along the upper end edge of the panel body 6, and the opening 3 of the front body 2. It adheres closely to the edge surface 3a.

  The protruding portion 12 is inclined obliquely forward (upwardly obliquely forward) from the seal outer wall portion 13 side, which is the base end side, toward the protruding distal end 12a side. Further, the plate thickness of the protruding portion 12 is gradually tapered 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.

  The seal outer wall portion 13 and the seal inner wall portion 14 are respectively attached to the upper surface (outer surface) 7a and the lower surface (inner surface) 7b of the panel upper edge portion 7 from the left end to the right end of the upper end edge of the panel body 6 when the seal is mounted. The upper sealing material 10 seals between the opening 3 and the front panel 6 when the protruding portion 12 is in close contact with the edge surface 3 a of the opening 3.

  According to the present embodiment, the seal outer wall portion 13 and the seal inner wall portion 14 are respectively provided on the upper surface 7a and the lower surface 7b of the panel upper edge portion 7 from the left end to the right end of the upper end edge of the panel body 6 in the seal mounting state. Since the end (rear end) of the panel upper edge portion 7 is reliably covered with the mounting portion 11 in the state of being in close contact, the panel upper edge portion 7 is specially processed (for example, burr generated on the cut surface of the end is polished by polishing). After removal, the rust prevention property of the panel upper edge portion 7 can be enhanced by the mounting portion 11 of the upper sealing material 10 without sufficiently coating the end of the panel upper edge portion 7.

  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.

  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.
