Summary of the Invention

Problems to be Solved by the Invention

[0004] There is room for improvement in the sealing performance between the body frame member provided at the front part of the vehicle and the dash panel in the invention of Patent Document 1 above.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle body structure capable of preventing a liquid adhering to the front surface of a resin dash panel supported by a die-cast front frame member from passing backward between the front frame member and the dash panel.

Means for Solving the Problems

[0006] A vehicle body structure according to a first aspect includes a die-cast front frame member including left and right front wheel houses and a lower wall portion connecting the left and right front wheel houses and extending in the vehicle up-and-down direction, and a resin dash panel attached to the lower wall portion. The dash panel includes a bent portion that bends so as to cover an upper edge portion of the lower wall portion from above and rearward of the vehicle, and a sealing material is provided in a liquid-tight state between the upper edge portion and the bent portion.

[0007] The die-cast front frame member of the vehicle body structure in the first embodiment comprises left and right front wheelhouses and a lower side wall portion that connects the left and right front wheelhouses and extends in the vertical direction of the vehicle. A resin dash panel is attached to the lower side wall portion, and the dash panel has a curved portion that bends so as to cover the upper edge of the lower side wall portion from the upper and rear sides of the vehicle. Furthermore, a sealing material is provided in a liquid-tight state between the upper edge of the lower side wall portion and the curved portion of the dash panel. Therefore, in the vehicle body structure in the first embodiment, liquid adhering to the front surface of the dash panel can be prevented from passing rearward between the front frame member and the dash panel by the sealing material provided between the front frame member and the dash panel.

[0008] The second embodiment of the vehicle body structure, in the first embodiment, comprises a dash panel located on the front side of the vehicle from the curved portion and extending upward from the curved portion, and a protruding portion extending toward the front of the vehicle from the connection between the curved portion and the lower end of the vertical extension.

[0009] The dash panel of the second embodiment of the vehicle body structure includes a vertical extension portion located on the front side of the vehicle from the curved portion and extending upward from the curved portion, and a protruding portion extending toward the front of the vehicle from the connection portion between the curved portion and the lower end of the vertical extension portion. As a result, liquid adhering to the front surface of the vertical extension portion of the dash panel is less likely to flow between the front frame member and the dash panel. [Effects of the Invention]

[0010] As described above, the vehicle body structure according to the present invention has the excellent effect of preventing liquid adhering to the front surface of the resin dash panel supported by the die-cast front frame member from passing through to the rear between the front frame member and the dash panel. [Brief explanation of the drawing]

[0011] [Figure 1] This is an exploded perspective view of the front frame member and dash panel as seen from the rear according to the embodiment. [Figure 2] This is a front view of the dashboard. [Figure 3] This is a front-view perspective showing a magnified portion of the dashboard panel. [Figure 4] This is a cross-sectional view along the line 4-4 in Figure 1. [Modes for carrying out the invention]

[0012] The vehicle body structure according to the embodiment will be described below with reference to the attached drawings. The arrows UP, FR, and LH in each drawing indicate the upper side in the vertical direction of the vehicle, the front side in the longitudinal direction of the vehicle, and the left side in the lateral direction of the vehicle, respectively.

[0013] As shown in Figure 1, the vehicle 10 to which the body structure of this embodiment is applied includes a front frame member 15, which is an integrally molded product made of die-cast aluminum, as part of the body frame members. The front frame member 15 includes a pair of left and right front wheel houses 17 and a lower wall portion 19 that connects the rear ends of the left and right front wheel houses 17. The lower wall portion 19 is a plate-shaped member that is substantially perpendicular to the front-rear direction. The upper edge portion 20 of the lower wall portion 19 is located below the upper ends of the left and right front wheel houses 17. Furthermore, in a front view, the upper edge portion 20 is recessed so as to be convex downwards. When the front frame member 15 is mounted on the vehicle 10, an engine room is formed directly in front of the lower wall portion 19, and the interior space (cabin) is formed directly behind the lower wall portion 19.

[0014] A dash panel 25, which is a single molded resin part, is attached to the front frame member 15. The dash panel 25 is a plate-shaped member. In a front view, the lower part of the dash panel 25 has a roughly downward-facing convex shape.

[0015] As shown in Figures 1, 2, and 4, a stepped portion 28 is formed at the bottom of the dash panel 25. The front shape of the stepped portion 28 is substantially the same as the upper edge 20 of the lower side wall portion 19 of the front frame member 15. The left end of the stepped portion 28 is located to the right of the left end surface of the dash panel 25, and the right end of the stepped portion 28 is located to the left of the right end surface of the dash panel 25. The portion of the dash panel 25 located above the stepped portion 28 is the upper flat portion (vertically extended portion) 29, and the portion located below the stepped portion 28 is the lower flat portion 30. As shown in Figure 4, the lower edge of the upper flat portion 29 is connected to the front edge of the stepped portion 28, and the upper edge of the lower flat portion 30 is connected to the rear edge of the stepped portion 28. The upper flat portion 29 and the lower flat portion 30 are substantially perpendicular to the longitudinal direction of the vehicle. As shown in Figures 1 and 4, the lower flat portion 30 is offset rearward from the upper flat portion 29. Furthermore, the stepped portion 28 and the upper edge of the lower flat portion 30 constitute the curved portion 32. As is clear from Figure 4, the cross-sectional shape of the curved portion 32 is approximately L-shaped. In addition, a protruding ridge 34 is provided projecting toward the front of the vehicle from the connection point between the front edge of the curved portion 32 (the front edge of the stepped portion 28) and the lower edge of the upper flat portion 29. The frontal shape of the protruding ridge 34 is approximately the same as that of the stepped portion 28. The protruding ridge 34 is formed on the dash panel 25 over almost the entire area of ​​the stepped portion 28 in the left-right direction.

[0016] Furthermore, as shown in Figures 2 and 3, a sealing material 40 having a substantially annular front shape is fixed in a liquid-tight state to the front surface of the dash panel 25. The sealing material 40 is elastically deformable. In a front view, a stepped portion 28 (protruding portion 34) is located on the inner circumference side of the sealing material 40. More specifically, in a front view, the lower part 41 of the sealing material 40 is located directly below the stepped portion 28 (protruding portion 34), and a small vertical gap is formed between the stepped portion 28 (protruding portion 34) and the lower part 41. The front shape of the lower part 41 is substantially the same as the front shape of the stepped portion 28 (protruding portion 34).

[0017] When attaching the dash panel 25 integrated with the sealing material 40 to the front frame member 15, as shown in FIG. 1, the dash panel 25 is brought close to the lower side wall portion 19 from behind the front frame member 15. Further, while bringing the lower end portion of the dash panel 25 into contact with the upper end portion of the lower side wall portion 19 (refer to the phantom line in FIG. 1), the stepped portion 28 (ridge portion 34) is positioned directly above the upper edge portion 20 of the lower side wall portion 19, and the lower portion 41 of the sealing material 40 is pressed against the upper edge portion 20 (refer to FIG. 4). Thereby, the bent portion 32 covers the upper edge portion 20 of the lower side wall portion 19 from the upper side and the rear side of the vehicle. Further, a part of the lower portion 41 of the sealing material 40 is deformed upward by the upper edge portion 20 of the lower side wall portion 19, and the lower portion 41 comes into contact with the upper edge portion 20 of the lower side wall portion 19 in a liquid-tight state. For the sake of convenience, in FIG. 4, a relatively large gap is formed between the rear surface of the lower side wall portion 19 and the front surface of the lower flat portion 30, but actually, the gap between the rear surface of the lower side wall portion 19 and the front surface of the lower flat portion 30 is minute.

[0018] Furthermore, a plurality of locations of the lower end portion of the dash panel 25 and the upper end portion of the lower side wall portion 19 that overlap each other in the front-rear direction are fixed to each other. Thereby, the front frame member 15 and the dash panel 25 are integrated with each other.

[0019] (Function and Effect) Next, the function and effect of the present embodiment will be described.

[0020] Here, assume a case where a liquid W such as rain adheres to the front surface of the upper flat portion 29 of the dash panel 25 as shown in FIG. 4. These liquids W flow downward along the front surface of the upper flat portion 29. This liquid W may flow forward along the upper surface of the ridge portion 34. In this case, the liquid W is highly likely to fall downward from the front end surface of the ridge portion 34. In other words, the possibility that this liquid W flows from the front end surface of the ridge portion 34 to the lower surface of the ridge portion 34 is small.

[0021] Next, assume a case where the liquid W flows from the front end face of the ridge portion 34 to the lower surface of the ridge portion 34. As described above, the bent portion 32 covers the upper edge portion 20 of the lower side wall portion 19 from the upper side and the rear side of the vehicle. Further, a sealing material 40 is provided in a liquid-tight state between the upper edge portion 20 of the lower side wall portion 19 and the bent portion 32. Therefore, even if the liquid W adhering to the lower surface of the ridge portion 34 flows backward along the ridge portion 34, the sealing material 40 prevents this liquid W from passing backward between the upper edge portion 20 of the lower side wall portion 19 of the front skeleton member 15 and the bent portion 32 of the dash panel 25. Therefore, there is almost no possibility that this liquid W will go toward the minute gap between the rear surface of the lower side wall portion 19 and the front surface of the lower plane portion 30.

[0022] As described above, the vehicle body structure in the vehicle according to the embodiment has been described, but these can be appropriately designed and changed within a range not departing from the gist of the present invention.

[0023] For example, the front edge portion of the ridge portion 34 provided on the dash panel 25 may be located above the rear edge portion of the ridge portion 34.

[0024] The ridge portion 34 may be omitted from the dash panel 25.
