Modes for Carrying Out the Invention

[0018] 〔First Embodiment〕 Hereinafter, the dash panel according to the first embodiment will be described with reference to the drawings. In each figure, the arrow UP indicates the upper side in the vertical direction of the vehicle, and the arrow FR indicates the front side in the front-rear direction of the vehicle.

[0019] [Configuration of Dash Panel 40] As shown in FIG. 1, the dash panel 40 is provided at the front part of the vehicle 10 and partitions the interior of the passenger compartment 2 and the front compartment 4 as the exterior of the passenger compartment 2. The dash panel 40 is formed in a plate shape with the front-rear direction of the vehicle as the thickness direction, and partitions the front compartment 4 and the passenger compartment 2 in the front-rear direction of the vehicle. An opening 40A penetrating in the front-rear direction of the vehicle is formed in the dash panel 40.

[0020] Interior parts 20 such as an instrument panel 21 are provided on the front side of the vehicle inside the passenger compartment 2. Exterior parts 30 such as a motor 31 as a drive source are arranged in the front compartment 4.

[0021] As shown in FIG. 2, the dash panel 40 includes a resin panel 42 and a dash silencer 44.

[0022] (Resin Panel 42) The resin panel 42 is made of resin and is formed in a plate shape with the front-rear direction of the vehicle as the thickness. The resin panel 42 is provided at the front part of the vehicle and partitions the interior of the passenger compartment 2 and the front compartment 4. The resin panel 42 is formed with unevenness to avoid interference with the interior parts 20 and the exterior parts 30.

[0023] A plurality of panel openings 42A are formed in the resin panel 42. The panel openings 42A are formed as through holes penetrating in the front-rear direction of the vehicle.

[0024] The opening edge 42C that forms the panel opening 42A is formed thicker than the other general part 42B. In other words, the opening edge 42C is formed to have a greater thickness in the plate thickness direction than the general part 42B other than the opening edge 42C of the resin panel 42. The opening edge 42C is formed to protrude forward from the general part 42B toward the vehicle front. An insertion component 8 described later may be attached to the opening edge 42C.

[0025] (Dash silencer 44) The dash silencer 44 is disposed on the vehicle rear side of the resin panel 42. The dash silencer 44 is disposed on the inner surface of the resin panel 42 on the vehicle interior side and is integrally formed with the resin panel 42. The dash silencer 44 is in close contact with the resin panel 42 over the entire surface. The dash silencer 44 is formed with irregularities to avoid interference with the interior parts 20 and exterior parts 30.

[0026] The dash silencer 44 can be, for example, a resin foam. Note that the dash silencer can be formed of a material that generates sound insulation performance and sound absorption performance, and can be, for example, polyurethane, felt, non-woven fabric, or the like.

[0027] A plurality of silencer openings 44A are formed in the dash silencer 44. The silencer openings 44A are formed as through holes penetrating in the vehicle front-rear direction. The panel opening 42A formed in the resin panel 42 and the silencer openings 44A formed in the dash silencer 44 are formed at the same position and with the same size in a front view, and form the opening 40A of the dash panel 40.

[0028] An insertion component 8 disposed across the passenger compartment 2 and the front compartment 4 is inserted into the opening 40A of the dash panel 40. Examples of the insertion component 8 include a wire harness that connects the exterior parts 30 and the interior parts 20, an air duct, a brake operating device, and the like.

[0029] [Manufacturing method of dash panel 40] The dash panel 40 is formed by integrally molding the dash silencer 44 and the resin panel 42 through insert molding in which the dash silencer 44 is set in a mold as an insert part and resin is filled around it.

[0030] [Function] The dash panel 40 according to the first embodiment includes a resin panel 42 made of resin that is provided at the front part of the vehicle and partitions the interior of the passenger compartment 2 and the front compartment 4, and a dash silencer 44 that is disposed on the surface of the resin panel 42 on the inner side of the passenger compartment 2 and is integrally molded with the resin panel 42 (see FIG. 1).

[0031] Since the dash panel 40 includes the dash silencer 44 that is disposed on the surface of the resin panel 42 on the inner side of the passenger compartment 2 and is integrally molded with the resin panel 42, the labor of attaching the dash silencer 44 to the resin panel 42 can be saved. Moreover, compared with the case of attaching the dash silencer 44 to the resin panel 42, the dash silencer 44 is disposed at the target position with respect to the resin panel 42. As a result, the productivity of the dash panel 40 can be improved, and the sound insulation performance of the dash panel 40 can be improved.

[0032] By the way, in the conventional sheet metal dash panel and dash silencer 44, an opening for attaching vehicle parts (for example, a brake operating device, an air duct, a harness, etc.) that communicate the front compartment 4 and the interior of the passenger compartment 2 is provided. And when attaching the dash silencer 44 to the dash panel, the opening formed in the dash silencer 44 is formed larger than the opening formed in the dash panel to absorb the mounting variation of the dash silencer 44 to the dash panel. Therefore, there is a problem that the area of the dash silencer 44 is reduced by the enlarged opening, and the sound insulation performance of the dash panel is deteriorated.

[0033] In the dash panel 40 according to the first embodiment, the panel opening 42A formed in the resin panel 42 is formed at the same position and with the same size as the silencer opening 44A formed in the dash silencer 44 in a front view (see FIG. 2).

[0034] Since the panel opening 42A formed in the resin panel 42 is formed at the same position and with the same size as the silencer opening 44A formed in the dash silencer 44 in a front view, the panel opening 42A and the silencer opening 44A are of the same size. Therefore, the sound insulation performance of the dash panel 40 can be improved.

[0035] By the way, when attaching the dash silencer 44 to a conventional dash panel made of a steel plate, fasteners such as clips were used. Therefore, a gap was formed between the dash silencer 44 and the dash panel in a portion not attached by the fastener, and there was a problem that the dash silencer 44 rattled.

[0036] In the dash panel 40 according to the first embodiment, the dash silencer 44 is in close contact with the resin panel 42 over the entire surface (see FIG. 2).

[0037] Since the dash silencer 44 is in close contact with the resin panel 42 over the entire surface, no gap is formed between the dash silencer 44 and the resin panel 42. Therefore, rattling of the dash silencer 44 can be avoided, and the sound insulation performance of the dash panel 40 can be improved.

[0038] By the way, in a conventional dash panel, when attaching a vehicle part to an opening, it was attached via a reinforcing part that reinforces the periphery of the opening of the dash panel. Therefore, there was a problem that the number of parts increased and the configuration became complicated.

[0039] In the dash panel 40 according to the first embodiment, the opening edge 42C forming the panel opening 42A is formed thicker than the other general part 42B (see FIG. 2).

[0040] The opening edge 42C forming the panel opening 42A is formed thicker than the other general part 42B, so that the periphery of the panel opening 42A of the resin panel 42 is reinforced. Therefore, with a simple configuration, the periphery of the opening 40A of the dash panel 40 can be reinforced.

[0041] 〔Second Embodiment〕 The dash panel of the second embodiment is different from the dash panel of the first embodiment in that the configuration of the resin panel is different. For the description of the parts that are the same as or equivalent to those described in the first embodiment, the same terms or the same reference numerals will be used for the description.

[0042] As shown in FIG. 3, ribs 42D protruding forward of the vehicle are formed around the panel opening 42A of the resin panel 42 from the general part 42B. A plurality of ribs 42D can be formed around the panel opening 42A.

[0043] Since the ribs 42D are formed around the panel opening 42A in the resin panel 42, the periphery of the panel opening 42A is reinforced. Therefore, with a simple configuration, the periphery of the panel opening 42A can be reinforced.

[0044] Note that since the other configurations and effects are substantially the same as those of the first embodiment described above, the description thereof will be omitted.

[0045] As described above, the dash panel according to the embodiment has been described based on the first embodiment and the second embodiment. However, the specific configuration is not limited to these embodiments, and design changes and the like are allowed as long as the gist of the invention according to each claim of the claims is not deviated from.

[0046] In the first embodiment, the opening edge 42C forming the panel opening 42A of the resin panel 42 is formed thicker than the general portion 42B. In the second embodiment, an example is shown in which ribs 42D are formed around the panel opening 42A of the resin panel 42. However, as shown in FIG. 4, the opening edge 42C forming the panel opening 42A of the resin panel 42 may be formed thicker than the general portion 42B, and further, ribs 42D may be formed around the panel opening 42A of the resin panel 42. Note that, in the resin panel 42, the opening edge 42C forming the panel opening 42A of the resin panel 42 does not necessarily have to be formed thicker than the general portion 42B, and ribs 42D do not necessarily have to be formed around the panel opening 42A of the resin panel 42.

[0047] In the second embodiment, an example is shown in which the rib 42D protrudes forward of the vehicle from the general portion 42B. However, the rib may protrude rearward of the vehicle from the general portion 42B, or may protrude both forward and rearward of the vehicle from the general portion 42B.
