Abstract

[Problem] To provide a dash panel that can reduce noise traveling from the front compartment into the cabin. [Solution] The dash panel comprises a main body that separates the passenger compartment from the front compartment, a rib 30 protruding from the surface of the main body, and a sheet-like silencer 40 covering the surface of the main body. The silencer 40 has a first slit 41 extending in the Y direction, a second slit 42 extending in the Y direction and spaced apart in the X direction which intersects the Y direction with the first slit 41, and a third slit 43 extending in the X direction and connecting the first slit 41 and the second slit 42. The rib 30 is inserted through the third slit 43. [Selection Diagram] Figure 5

Description

This invention relates to a dashboard panel. Patent Document 1 discloses a front structure for an automobile comprising a cowl extending in the vehicle width direction and positioned along the lower edge of the automobile's windshield, and a dash panel connected to the lower part of this cowl to separate the passenger compartment side from the engine compartment side. Japanese Patent Publication No. 2009-113568 This is a front view showing a dashboard panel according to an embodiment.This is an enlarged view showing the main part (part A) of Figure 1.This is a perspective view showing an enlarged view of the main part (part A) of Figure 1.This is a front view showing a slit provided in the silencer of the dashboard panel according to the embodiment.This is a front view showing the slits and ribs provided in the silencer of the dash panel according to the embodiment.This is a cross-sectional view taken along the line B-B in Figure 5.This is a front view showing a slit provided in the silencer of the dashboard panel according to a modified embodiment. Hereinafter, embodiments of the dash panel 10 according to the present invention will be described with reference to Figures 1 to 7. In Figure 1, arrow LH indicates the left side of the vehicle in the left-right direction, and arrow UP indicates the top of the vehicle in the up-down direction. Furthermore, the forward/backward direction, left-right direction, and up-down direction in the following description refer to the forward/backward direction, left-right direction, and up-down direction of the vehicle, respectively. Also, the left-right direction refers to the left-right direction when the vehicle is facing forward. Furthermore, the arrow X shown in Figures 4 to 7 indicates the longitudinal direction of the rib 40 provided on the dash panel 10. Arrow Y indicates the short direction of the rib 30, and arrow Z is perpendicular to arrows X and Y, indicating the protruding direction of the rib 30. Furthermore, for illustrative purposes, the silencer 30 is omitted in Figures 1 to 3. [vehicle] The dash panel 10 according to this embodiment is applied to, for example, a battery-powered electric vehicle (BEV). However, the vehicles to which the dash panel 10 according to this embodiment can be applied are not limited to BEVs. For example, the dash panel 10 according to this embodiment may be applied to a fuel cell vehicle or the like. [Dash Panel] The dashboard panel 10 is located at the front of the vehicle. More specifically, the dashboard panel 10 is located between the passenger compartment and the front compartment. As shown in Figure 1, the dashboard panel 10 is located above the vehicle frame 11 and is fixed to the vehicle frame 11. The dash panel 10 comprises a main body 20 that separates the passenger compartment from the front compartment, ribs (projections) 30 that protrude from the surface of the main body 20, and a sheet-like silencer 40 (see Figures 4 to 6) that covers the surface of the main body 20. The main body 20 is a resin panel-shaped component, arranged so that its surface includes both the vertical and horizontal directions of the vehicle. The main body 20 separates the passenger compartment from the front compartment. The main body 20 is formed with irregularities to avoid interference with interior and exterior components. As shown in Figure 1, multiple bolt holes (not shown) are formed in the lower part of the main body 20 in the thickness direction (in this embodiment, the vehicle's longitudinal direction). These multiple bolt holes are arranged at predetermined intervals along the lower edge of the main body 20. The dash panel 22 is fixed to the vehicle frame 11 by inserting bolts through each of these bolt holes (not shown). Various vehicle components are attached to the passenger compartment side of the main body 20 via brackets and the like. For example, a wire harness 22 and piping 23 are attached to the passenger compartment side of the main body 20. The wire harness 22 is provided so as to follow the passenger compartment side of the main body 20. The wire harness 22 has a first portion 22A extending vertically from the central part of the main body 20 in the vehicle width direction, a second portion 22B bending from the upper end of the first portion 22A and extending outward along the upper end of the main body 20 in the vehicle width direction, and a third portion 22C bending from the outer end of the second portion 22B in the vehicle width direction and extending outward and downward in the vehicle width direction. The rib 30 protrudes from the main body 20, as shown in Figures 2 and 3. The rib 30 is a plate-shaped member, with its end face connected to the main body 20. In a plan view, the rib 30 is positioned to be inclined in the vertical and vehicle width directions. In a plan view, the rib 30 is positioned to follow the wire harness 22. The rib 30 is provided so as to penetrate the silencer 40, as shown in Figures 5 and 6
