Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a panel provided between the outside and the inside of the vehicle, such as a dash panel, there may be provided a component engagement portion with which components constituting the vehicle, such as a pedal unit sub-assembly, engage. In this case, it is desirable to suppress the intrusion of noise from the periphery of the component engagement portion, but there is room for improvement in this regard in the structure described in Patent Document 1 above.

[0005] In consideration of the above facts, an object of the present invention is to obtain a panel structure of a vehicle that can suppress the intrusion of noise from the periphery of the component engagement portion into the vehicle interior.

Means for Solving the Problems

[0006] The panel structure of the vehicle in the first embodiment comprises a panel formed from a resin material and provided between the outside and inside of the vehicle, a component engagement portion provided on the panel and into which components constituting the vehicle engage, and a noise reduction portion formed integrally with the panel and provided along the component engagement portion, which blocks noise from the outside of the vehicle to the inside of the vehicle.

[0007] According to the first embodiment of the vehicle panel structure, a panel provided between the exterior and interior of the vehicle is formed from a resin material. This panel is provided with component engagement portions into which vehicle components engage. Furthermore, a noise reduction portion, integrally formed with the panel, is provided along the component engagement portion. This allows noise from the vicinity of the component engagement portion to enter the interior of the vehicle to be blocked by the noise reduction portion. Thus, according to the first embodiment of the vehicle panel structure, the intrusion of noise from the vicinity of the component engagement portion into the interior of the vehicle can be suppressed.

[0008] The panel structure of the vehicle in the second embodiment is provided with a sound-absorbing member that reduces noise from the outside of the vehicle interior to the inside of the vehicle interior along the inside surface of the panel, and a through hole is formed in the sound-absorbing member at a location corresponding to the component engagement portion, and the noise reduction portion closes the inside surface of the through hole.

[0009] According to the second embodiment of the vehicle panel structure, the interior side of the through-hole formed in the sound-absorbing member is closed by the noise reduction unit. This effectively suppresses the intrusion of noise into the interior of the vehicle through the through-hole formed in the sound-absorbing member.

[0010] The panel structure of the vehicle in the third embodiment is the same as the panel structure of the vehicle in the first embodiment, wherein the component engagement portion is an insertion hole that penetrates the panel and into which a component constituting the vehicle is inserted, and the noise reduction portion is a thickened portion formed along the insertion hole, and the thickness dimension of the thickened portion is set to be larger than the thickness dimension of the portion of the panel surrounding the thickened portion.

[0011] According to the third embodiment of the vehicle panel structure, the components constituting the vehicle are inserted into insertion holes formed in the panel. Furthermore, a thickened section, which serves as a noise reduction section, is provided around the insertion holes in the panel. The thickness of this thickened section is set to be larger than the thickness of the surrounding area of ​​the panel. This effectively suppresses the intrusion of noise from around the insertion holes in the panel into the interior of the vehicle. [Effects of the Invention]

[0012] The vehicle panel structure according to the present invention has the excellent effect of being able to suppress the intrusion of noise into the interior of the vehicle from the vicinity of the component engagement part. [Brief explanation of the drawing]

[0013] [Figure 1] This is a schematic side cross-sectional view showing a dash panel and the like to which the panel structure of the vehicle according to the first embodiment is applied. [Figure 2] This is a schematic side cross-sectional view showing a dash panel and the like to which the panel structure of the vehicle according to the second embodiment is applied. [Modes for carrying out the invention]

[0014] (Panel structure of the vehicle in the first embodiment) The panel structure of the vehicle according to the first embodiment of the present invention will be described with reference to Figure 1. In each figure, the arrow FR indicates the front side in the longitudinal direction of the vehicle, and the arrow UP indicates the upper side in the vertical direction of the vehicle. Furthermore, when simply referring to the longitudinal, left-right, and up-down directions below, unless otherwise specified, they refer to the longitudinal direction of the vehicle, the left-right direction (vehicle width direction), and the up-down direction of the vehicle.

[0015] Figure 1 shows a dash panel 10 and the like to which the panel structure of the vehicle according to the first embodiment is applied. The dash panel 10 is a component that separates the power unit room 12 (outside the passenger compartment) where the power unit and the like are housed from the passenger compartment 14, and is formed using a resin material. More specifically, the dash panel 10 includes a front wall portion 16 that extends in the vertical and horizontal directions, and a component fixing portion 20 which serves as a component engagement portion to which vehicle components 18 (for example, a brake pedal) are fixed.

[0016] The component fixing portion 20 is formed in a cylindrical shape with the front-to-back direction as its axial direction and includes a cylindrical portion 22 that protrudes from the front wall portion 16 toward the rear. The front side of this cylindrical portion 22 is closed off by a part 24 of the front wall portion 16.

[0017] A stud bolt 26 is inserted into the cylindrical portion 22. The front end of the stud bolt 26 is fixed to the center of a portion 24 of the front wall portion 16. The rear portion of the stud bolt 26 protrudes from the cylindrical portion 22 toward the rear. By screwing a nut 28 onto the stud bolt 26, the vehicle component 18 is fixed to the component fixing portion 20.

[0018] On the side of the dash panel 10 facing the passenger compartment 14, a sound-absorbing member 30 is provided to reduce noise from the power unit room 12 to the passenger compartment 14. This sound-absorbing member 30 is shaped to conform to the passenger compartment 14 side of the dash panel 10 and is attached to the passenger compartment 14 side of the dash panel 10. In addition, a through hole 32 is formed in the sound-absorbing member 30 at a location corresponding to the component fixing portion 20, and the through hole 32 is penetrated through the sound-absorbing member 30. When viewed from the front or rear direction, the shape of this through hole 32 is circular. Furthermore, the inner diameter D1 of the through hole 32 is set to be larger than the outer diameter D2 of the cylindrical portion 22. The cylindrical portion 22 is positioned inside this through hole 32.

[0019] In addition, the dash panel 10 includes a noise reduction portion 34 that protrudes radially outward from the rear end portion of the cylindrical portion 22 toward the outside of the diameter of the cylindrical portion 22. The noise reduction portion 34 is formed in an annular shape when viewed in the front-back direction. Further, the outer diameter D3 of the noise reduction portion 34 is set to an outer diameter larger than the inner diameter D1 of the through hole 32 formed in the sound absorption member 30. Furthermore, the distance C between the noise reduction portion 34 and the front wall portion 16 is set to a dimension substantially the same as the thickness dimension T1 of the sound absorption member 30. As a result, the noise reduction portion 34 is in a state of closing the vehicle interior 14 side of the through hole 32 formed in the sound absorption member 30.

[0020] In the present embodiment described above, the noise reduction portion 34 closes the vehicle interior 14 side of the through hole 32 formed in the sound absorption member 30. In other words, the portion of the dash panel 10 not covered by the sound absorption member 30 has a double structure of resin sandwiching an air layer (a double structure formed by the front wall portion 16 and the noise reduction portion 34). Thereby, the intrusion of noise from the through hole 32 formed in the sound absorption member 30 into the vehicle interior 14 side can be effectively suppressed.

[0021] In addition, in the present embodiment, the dash panel 10 is formed using a resin material. Thereby, the range from the front wall portion 16 to the cylindrical portion 22 and the noise reduction portion 34 can be integrally formed.

[0022] (Panel structure of the vehicle of the second embodiment) Next, the panel structure of the vehicle of the second embodiment of the present invention will be described with reference to FIG. 2.

[0023] FIG. 2 shows a dash panel 10 and the like to which the panel structure of the vehicle of the second embodiment is applied. The dash panel 10 is formed using a resin material as in the above-described first embodiment. More specifically, the dash panel 10 includes a front wall portion 16 that extends in the vertical direction and the horizontal direction, and an inclined wall portion 40 having an insertion hole 38 as a component engagement portion into which components 36 (such as a steering shaft, wiring, and piping) constituting the vehicle are inserted.

[0024] The inclined wall portion 40 slopes forward as it extends upward. This inclined wall portion 40 is connected to the front wall portion 16 via a connecting portion 42. A circular insertion hole 38 is formed in the inclined wall portion 40. A cylindrical sealing member 44 is attached to the edge of this insertion hole 38. The vehicle component 36 is inserted into the insertion hole 38 with the sealing member 44 inserted into it. The first lip portion 46 and the second lip portion 48 of the sealing member 44 are in contact with the outer circumferential surface of the vehicle component 36 around its entire circumference.

[0025] On the side of the dash panel 10 facing the passenger compartment 14, a sound-absorbing member 30 similar to that in the first embodiment is provided. In this sound-absorbing member 30, the portion corresponding to the inclined wall portion 40 is cut out. That is, a cutout hole 50 is formed in the portion of the sound-absorbing member 30 corresponding to the inclined wall portion 40.

[0026] Furthermore, a thickened section 52, which functions as a noise reduction section 34, is formed in the inclined wall section 40. This thickened section 52 is formed in an annular shape surrounding the insertion hole 38. In addition, the thickness dimension T2 of the thickened section 52 is set to be larger than the thickness dimension T3 of the connecting section 42.

[0027] In the embodiment described above, a thickened portion 52, which functions as a noise reduction portion 34, is provided around the insertion hole 38 in the inclined wall portion 40. The thickness dimension T2 of this thickened portion 52 is set to be larger than the thickness dimension of the portion of the dash panel 10 around the thickened portion 52 (thickness dimension T3 of the connection portion 42). This effectively suppresses the intrusion of noise from around the insertion hole 38 in the dash panel 10 into the vehicle interior 14.

[0028] In the first and second embodiments described above, examples were given in which the structure of the present invention is applied to a dash panel 10, but the present invention can also be applied to other panels. For example, the structure of the present invention can also be applied to floor panels and door panels.

[0029] Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to the above, and can be implemented in various other ways without departing from the spirit of the invention. [Explanation of symbols]
