Description

Technical Field

[0001] The present disclosure relates to an instrument panel of a vehicle. More specifically, the present disclosure relates to measures for suppressing liquid from dripping into the interior of the instrument panel when liquid is spilled on the instrument panel. Generally, an instrument panel in a narrow sense refers to an instrument unit in front of a driver's seat. However, an instrument panel in the present specification refers to a component (including a portion called a front fender) arranged between one end and the other end of a vehicle compartment in a vehicle width direction at a front area of ​​the vehicle compartment. That is, the instrument panel in the present specification is an instrument panel in a broad sense. Background Art

[0002] Generally, as disclosed in Japanese Examined Patent Publication No. 7-90731 (JP 7-90731B), for example, a wiring harness for supplying power and transmitting control signals to various electrical components installed in a vehicle and a wiring harness connector to which the wiring harness is connected are arranged inside a dashboard of the vehicle. JP 7-90731B discloses a configuration in which the dashboard includes two parts, an upper dashboard portion and a lower dashboard portion, arranged in an up-down direction, and a wiring harness arranged therebetween. Summary of the invention

[0003] Generally, the instrument panel has various openings such as an opening in which a speaker is installed. As described above, the wiring harness and the connector (hereinafter may be referred to as a target component) are arranged in the instrument panel, and some target components may even be arranged under the opening.

[0004] In such a configuration, when an occupant spills liquid on the dashboard (e.g., knocks over a cup of water or a plastic bottle), the liquid flows on the upper surface of the dashboard. The liquid flows along the slope of the upper surface of the dashboard. When there is any opening in the slope, the liquid may flow into the opening and then drip onto the target component through the opening. Therefore, liquid exposure precautions are required for the target component. The target components that require liquid exposure precautions are not limited to the above-mentioned wiring harnesses and connectors, but also include various components that may fail due to exposure to liquid.

[0005] As a liquid exposure prevention measure for the target components, it is possible to consider setting a liquid shielding plate or a drip-proof plate above each target component. In this case, the liquid shielding plate or the drip-proof plate will be produced as an additional component and installed to the instrument panel, etc. so as to be located above the target component in the instrument panel.

[0006] However, such measures may bring about various problems such as an increase in the number of parts, an increase in assembly man-hours, a significant increase in vehicle weight, and a significant increase in cost.

[0007] The present invention has been made in view of such problems, and an object of the present invention is to provide a vehicle dashboard which is constructed to suppress liquid from dripping into the interior of the dashboard without causing the above-mentioned problems (problems that may be caused by setting a liquid shielding plate or an anti-drip plate).

[0008] As a prerequisite, the technical solution for achieving the above-mentioned object of the present invention is applied to an instrument panel of a vehicle. The instrument panel includes: a groove extending in a direction intersecting with a vehicle width direction, and the groove is provided at a position deviated from the opening in the vehicle width direction on at least one side of the opening of the instrument panel in the vehicle width direction; and a restriction portion configured to restrict the liquid from flowing toward the opening when the liquid flows into the groove and overflows the groove.

[0009] In this specific configuration, if the occupant spills liquid (e.g., water) on the dashboard, the liquid flows on the upper surface of the dashboard. Once the liquid reaches the groove of the dashboard, the liquid flows along the groove. In other words, at least on one side of the opening in the vehicle width direction, at a position deviated from the opening in the vehicle width direction, the liquid flows in a direction intersecting the vehicle width direction (e.g., flowing in the front-rear direction of the vehicle). At this time, when the amount of spilled liquid is large and the liquid overflows the groove, the limiting portion restricts the liquid from flowing toward the opening. This inhibits the liquid from flowing into the opening, so that the liquid is inhibited from dripping into the interior of the dashboard through the opening. Even in the case where the target component (wiring harness or connector) to be prevented from being exposed to the liquid is arranged below the opening inside the dashboard, the liquid is also inhibited from dripping onto the target component. As described above, in the case where a liquid shielding plate or a drip-proof plate is arranged above each target component as a liquid exposure preventive measure, the liquid shielding plate or the drip-proof plate needs to be manufactured as an additional component and assembled to the dashboard, etc., so as to be located above the target component inside the dashboard. On the other hand, since the liquid is prevented from dripping into the interior of the instrument panel by the technical solution currently proposed for the above-mentioned problem, neither a liquid shielding plate nor an anti-drip plate is required. That is, the liquid is prevented from dripping onto the target component by the technical solution currently proposed without causing an increase in the number of components or an increase in assembly man-hours, and without causing a significant increase in vehicle weight or a substantial increase in cost.

[0010] A liquid guide is provided below the groove. The liquid guide is inclined so as to guide the liquid overflowing the groove in the direction intersecting the vehicle width direction. The restriction portion includes a first step portion which is provided continuously with a portion of the liquid guide on the opening side and extends upward to restrict the liquid flowing in the liquid guide from flowing toward the opening.

[0011] This structure allows the liquid overflowing the groove to be guided along the liquid guide in a direction intersecting the vehicle width direction. Since the first step portion (restriction portion) is provided continuously with the portion of the liquid guide on the opening side, the liquid flowing along the liquid guide is restricted by the first step portion from flowing toward the opening. This structure suppresses the liquid from dripping into the interior of the instrument panel through the opening.

[0012] The restriction portion includes a second step portion extending upward from an edge of the opening to restrict the liquid flowing on the upper surface of the instrument panel from flowing toward the opening.

[0013] In this structure, since the second step portion (restriction portion) is provided at the edge of the opening, even if the liquid overflowing the groove flows on the upper surface of the instrument panel, the second step portion restricts the liquid flowing on the upper surface of the instrument panel from flowing toward the opening. In this case, the liquid is also suppressed from dripping into the interior of the instrument panel through the opening.

[0014] The instrument panel includes an instrument panel body and an instrument panel cover installed above the instrument panel body. The opening is provided in the instrument panel body, the groove is integrally formed in the instrument panel cover, and the restriction portion is integrally formed in the instrument panel body.

[0015] In this way, when the instrument panel includes multiple components, by providing each component with a functional part for suppressing the flow of liquid into the opening (the groove of the instrument panel cover and the limiting part of the instrument panel body), the components effectively suppress the flow of liquid into the opening, and the components are easy to be formed.

[0016] The opening is a speaker mounting opening into which the speaker is to be assembled and mounted.

[0017] The speaker installation opening is a larger opening among various openings provided in the instrument panel. Therefore, there is a concern that if liquid is spilled on the instrument panel, the liquid may flow into the speaker installation opening. However, with the currently proposed technical solution, a groove and a restriction portion are provided to suppress the liquid from flowing into the speaker installation opening. As a result, the liquid can be suppressed from flowing into the speaker installation opening, and the liquid can be suppressed from dripping into the interior of the instrument panel through the speaker installation opening.

[0018] In the present invention, the instrument panel includes: a groove extending in a direction intersecting the vehicle width direction, and the groove is provided at a position deviated from the opening in the vehicle width direction on at least one side of the opening of the instrument panel in the vehicle width direction; and a restriction portion configured to restrict the flow of liquid toward the opening in the case where the liquid flows into the groove and overflows the groove. In this configuration, since the liquid is suppressed from dripping into the interior of the instrument panel, it is not necessary to provide a liquid shielding plate or a drip-proof plate. That is, in the present invention, in the case where the target component is arranged below the opening, the liquid is suppressed from dripping on the target component without causing an increase in the number of components or an increase in assembly man-hours, and without causing a significant increase in the weight of the vehicle or a substantial increase in cost.

[0024] Embodiments of the present invention will be described below with reference to the accompanying drawings. The embodiments to be described below are about a case where the present invention is applied to an instrument panel of a vehicle having a configuration in which speakers are respectively provided on opposite sides of the instrument panel in the vehicle width direction.

[0025] Figure 1 1 is a diagram illustrating a portion of a vehicle around an instrument panel 1 of a vehicle according to the present embodiment as viewed from the rear of the vehicle. Figure 1 , an arrow “UP” (UP) indicates an upward direction, an arrow “Right” (RH) indicates a right side of the vehicle in a vehicle width direction, and an arrow “Left” (LH) indicates a left side of the vehicle in the vehicle width direction.

[0026] like Figure 1As shown, the instrument panel 1 is arranged in front of the driver's seat and the passenger seat. The instrument panel 1 is an interior member that covers the portion of the vehicle in front of the driver's seat and the passenger seat, and has a laminated structure including, for example, a base material, a shock absorbing material, and a covering material. A center cluster 2 is arranged in the center of the instrument panel 1. The center cluster 2 includes a display 21 for a car navigation system and various switches. A steering wheel 3 is arranged on the right side of the instrument panel 1 in the vehicle width direction.

[0027] On the upper surface of the instrument panel 1, the speaker units 4 are arranged at positions respectively close to the left and right ends of the instrument panel 1. The configuration around the position where the speaker units 4 are located will be described below. Figure 2 For along Figure 1 A cross-sectional view taken along line II-II. Figure 2 , an arrow “UP” (UP) indicates an upward direction, an arrow “FR” (FR) indicates the front of the vehicle, and an arrow “RR” (RR) indicates the rear of the vehicle.

[0028] Figure 2 The cross-sectional view of FIG. 1 shows a front windshield 5, a cowl top panel 6, an instrument panel 1, a speaker unit 4, a speaker cover 7, and a wiring harness 8 as vehicle components. The wiring harness 8 is arranged in Figure 2 in the rectangular area shown.

[0029] The front windshield 5 is arranged at the front of the vehicle compartment in the front-rear direction of the vehicle. The cowl 6 extends in the vehicle width direction and supports the lower end of the front windshield 5. In the interior space S defined by the instrument panel 1, a wiring harness 8 for supplying power to various electrical components installed in the vehicle and transmitting control signals and a connector to which the wiring harness 8 is connected are arranged. In particular, in the case of a pure electric vehicle or a plug-in hybrid electric vehicle, a high-voltage wiring harness may be used as the wiring harness 8.

[0030] The instrument panel 1 includes speaker mounting portions 11. The speaker mounting portions 11 are arranged at the front end of the instrument panel 1 at opposite ends thereof in the vehicle width direction, respectively. The right speaker mounting portion 11 and the left speaker mounting portion 11 are arranged substantially symmetrically to each other.

[0031] Each speaker mounting portion 11 has an opening (hereinafter may be referred to as a speaker mounting opening) 12, and the speaker unit 4 is fitted into the opening (speaker mounting opening) 12 so that the speaker unit 4 is mounted in the instrument panel 1. The speaker cover 7 is provided above the speaker unit 4 so as to cover the entire area of ​​the speaker mounting portion 11. The speaker cover 7 has a grille (illustration omitted). The wire harness 8 and the connector (target component) are arranged below the opening 12.

[0032] The configuration of the portion of the instrument panel 1 around the speaker mounting portion 11 , that is, the feature of the present embodiment will now be described below. Figure 3 It is a perspective view showing part of the instrument panel 1 around the speaker mounting portion 11 . Figure 4 For along Figure 3 A cross-sectional view taken along line IV-IV. Figure 3 and Figure 4 , an arrow “UP” (UP) indicates an upward direction, an arrow “Right” (RH) indicates a right side of the vehicle in a vehicle width direction, and an arrow “Left” (LH) indicates a left side of the vehicle in the vehicle width direction. Figure 3 The figure shows that the speaker mounting portion 11 is arranged on the right side in the vehicle width direction in a state where the speaker cover 7 is removed. Figure 3 In the figure, the opening 12 of the speaker mounting portion 11 is visible.

[0033] like Figure 3 As shown, the instrument panel 1 includes an instrument panel body 13 made of resin, and an instrument panel cover 14 made of resin and mounted above the instrument panel body 13 (for example, fastened by snap fastening). Specifically, the instrument panel cover 14 is arranged at the following position: the position above the instrument panel body 13 and where the speaker cover 7 is mounted is on the inner side in the vehicle width direction. The upper surface of the speaker cover 7 and the upper surface of the instrument panel cover 14 are arranged to be flush with each other in a state where the speaker cover 7 is mounted above the instrument panel body 13 (see FIG. 1 ). Figure 1 ).

[0034] As described above, in a structure where the wiring harness and connector (target component) are arranged below the opening equipped with a speaker unit, when an occupant spills liquid on the dashboard (for example, knocks over a cup or plastic bottle filled with water), the liquid will flow on the upper surface of the dashboard. The liquid flows along the slope of the upper surface of the dashboard, and when there is an opening on the slope, the liquid may flow into the opening and drip onto the target component through the opening. Therefore, liquid exposure preventive measures for the target component are needed. As a liquid exposure preventive measure for the target component, it is possible to consider setting a liquid shielding plate or a drip-proof plate above each target component. In this case, the liquid shielding plate or the drip-proof plate will be produced as an additional component and assembled to the dashboard, etc., so as to be positioned above the target component in the dashboard. However, such measures may bring various problems, such as an increase in the number of parts, an increase in assembly man-hours, a significant increase in vehicle weight, and a substantial increase in cost.

[0035] In order to avoid causing the above-mentioned problems (problems that may be caused by providing a liquid shielding plate or a drip-proof plate), the present embodiment is configured to suppress liquid from dripping into the interior of the instrument panel 1 (dripping onto a target component) by providing each of the instrument panel body 13 and the instrument panel cover 14 with a functional portion for suppressing liquid from flowing into the opening 12. Specifically, the groove 15 is integrally formed into the instrument panel cover 14, and the first step portion 16 and the second step portion 17 as an example of a restricting portion are integrally formed into the instrument panel body 13. Next, the above configuration will be described in detail.

[0036] The groove 15 is provided at the outer end of the instrument panel cover 14 in the vehicle width direction and extends in the vehicle front-rear direction. Specifically, the instrument panel cover 14 includes an inner vertical wall 15a extending substantially in the vertical direction (in a direction substantially perpendicular to the vehicle width direction) at the outer end of the instrument panel cover 14 in the vehicle width direction, a bottom plate 15b extending outwardly in the vehicle width direction by a predetermined length from the lower end of the inner vertical wall 15a, and an outer vertical wall 15c extending upward from the outer end of the bottom plate 15b in the vehicle width direction. The space enclosed by the inner vertical wall 15a, the bottom plate 15b, and the outer vertical wall 15c is the groove 15 which opens upward and extends in the vehicle front-rear direction by a predetermined length.

[0037] The upper surface of the bottom plate 15b is an inclined surface that is inclined downward at a predetermined angle toward the inside of the vehicle compartment (toward the driver's seat and the passenger seat). In this configuration, when liquid flows into the groove 15, the liquid flows toward the inside of the vehicle compartment and flows out of the open end of the groove 15 on the inside of the vehicle compartment (see Figure 3 The arrow A) is indicated by a dotted line.

[0038] In view of the assumed amount of liquid spilled on the instrument panel by the occupant, the cross-sectional shape of the groove 15 determined by the height of the inner vertical wall 15a and the outer vertical wall 15c and the width of the bottom wall 15b (the dimension of the bottom wall 15b in the vehicle width direction) is appropriately determined by experiment or simulation. The cross-sectional shape of the groove 15 may be uniform or non-uniform in the extending direction of the groove 15.

[0039] In the present embodiment, the flange 15d is provided so as to extend slightly outward in the vehicle width direction from the upper end of the outer vertical wall 15c.

[0040] A liquid guide 18 is provided in the instrument panel body 13 at a position below the groove 15. When the amount of spilled liquid is large and the liquid overflows the groove 15, the liquid guide 18 has a function of receiving the liquid. The upper surface of the liquid guide 18 is an inclined surface that is inclined downward toward the inner side of the vehicle compartment (toward the driver's seat and the passenger seat). The inclined surface of the liquid guide 18 includes a front inclined surface 18a and a rear inclined surface 18b, wherein the front inclined surface 18a is arranged on the front side of the vehicle and has a smaller inclination angle, and the rear inclined surface 18b is continuously provided with the end of the front inclined surface 18a on the inner side of the vehicle compartment and has a larger inclination angle. The inclined surface of the liquid guide 18 is not limited to the above-mentioned configuration, but may be an inclined surface having a uniform inclination angle on the entire surface, or may include three or more inclined surfaces having different inclination angles from each other.

[0041] Since the liquid guide 18 is provided as described above, when the liquid overflows the groove 15 and drips onto the upper surface of the liquid guide 18 (see Figure 3 The liquid flows along the liquid guide 18 toward the inner side of the vehicle compartment (see arrow B indicated by the dotted line in FIG. Figure 3 The dashed line in FIG. 1 indicates the arrow C).

[0042] In addition, the instrument panel body 13 includes a first step portion 16 which is provided continuously with the outer end of the fluid guide 18 in the vehicle width direction (the portion of the fluid guide 18 on the opening side) and extends upward. The first step portion 16 has a function of restricting the liquid flowing in the fluid guide 18 from flowing toward the opening 12.

[0043] Specifically, the height of the first step portion 16 is predetermined by experiments or simulations to be a size such that the liquid surface of the liquid flowing along the liquid guide 18 does not exceed the height thereof (the upper end of the first step portion 16) even when the amount of liquid spilled is large. More specifically, the first step portion 16 includes a front step portion 16a that matches the front inclined surface 18a of the liquid guide 18 (arranged on the outer side of the front inclined surface 18a in the vehicle width direction) and a rear step portion 16b that matches the rear inclined surface 18b of the liquid guide 18 (arranged on the outer side of the rear inclined surface 18b in the vehicle width direction). The heights of the front step portion 16a and the rear step portion 16b are predetermined to be a size such that the liquid surface of the liquid flowing along the liquid guide 18 does not exceed the height thereof even when the amount of liquid spilled is large.

[0044] The instrument panel body 13 includes a second step portion 17 extending upward from the edge of the opening 12 on the inner side of the vehicle compartment. The second step portion 17 is provided continuously with the first step portion 16 on the outer side in the vehicle width direction and has a function of restricting the liquid flowing on the upper surface of the instrument panel 1 (see the Figure 3 The liquid flows toward the opening 12 as indicated by the dashed arrow D).

[0045] Specifically, the second step portion 17 includes a front-rear step portion 17a and a left-right step portion 17b, wherein the front-rear step portion 17a extends substantially in the vehicle front-rear direction (extends in a direction substantially perpendicular to the vehicle width direction), and the left-right step portion 17b is provided continuously with the end portion of the front-rear step portion 17a on the inner side of the vehicle compartment and extends substantially in the vehicle width direction (extends in a direction substantially perpendicular to the vehicle front-rear direction). The heights of the front-rear step portion 17a and the left-right step portion 17b are predetermined by experiments or simulations to be such that the liquid surface of the liquid flowing on the upper surface of the instrument panel 1 does not exceed the height thereof (the upper end of the second step portion 17) even when the amount of liquid spilled is large.

[0046] The flow of liquid when the occupant spills liquid on the instrument panel 1 will now be described below. In this case, the liquid flows on the upper surface of the instrument panel 1 (e.g., the upper surface of the instrument panel cover 14). When the amount of spilled liquid is small, once the spilled liquid reaches the groove 15 of the instrument panel cover 14, the spilled liquid flows along the groove 15. The liquid flows toward the inside of the vehicle compartment and flows out from the open end of the groove 15 on the inside of the vehicle compartment (see the flow through the groove 15). Figure 3 The dashed line in the figure indicates the arrow A).

[0047] On the other hand, when the amount of the spilled liquid is large and the liquid overflows the groove 15 and drips onto the upper surface of the liquid guide 18 (see Figure 3 The liquid flows along the liquid guide 18 toward the inner side of the vehicle compartment (see arrow B indicated by the dotted line in FIG. Figure 3 In this case, since the first step portion 16 is provided continuously with the outer end of the liquid guide 18 in the vehicle width direction (the portion of the liquid guide 18 on the opening 12 side), the liquid flowing in the liquid guide 18 is restricted from flowing toward the opening 12.

[0048] In the case where the liquid flows on the upper surface of the instrument panel body 13 after flowing along the liquid guide 18 (see Figure 3 As indicated by the dotted line in the figure (arrow D), since the second step portion 17 is provided at the edge of the opening 12 on the inner side of the vehicle compartment, the liquid flowing on the upper surface of the instrument panel body 13 is restricted from flowing toward the opening 12.

[0049] As described above, in the present embodiment, the instrument panel 1 includes a groove 15 at a position deviated from the opening 12 in the vehicle width direction, the groove 15 extending in a direction intersecting the vehicle width direction and arranged on one side of the opening 12 of the instrument panel 1 in the vehicle width direction, and the instrument panel 1 includes a first step portion 16 and a second step portion 17 as an example of a restriction portion, the restriction portion being configured to restrict the flow of liquid toward the opening 12 in the case where the liquid flows into the groove 15 and overflows the groove 15. In this configuration, since the liquid is suppressed from dripping into the interior of the instrument panel 1, it is not necessary to provide a liquid shielding plate or a drip-proof plate. That is, the present embodiment suppresses the liquid from dripping onto the target components (wiring harness 8 and connector) arranged below the opening 12 without causing an increase in the number of components or an increase in assembly man-hours, and without causing a significant increase in vehicle weight and a substantial increase in cost.

[0050] In the present embodiment, the groove 15 is integrally formed into the instrument panel cover 14, and the first step portion 16 and the second step portion 17 are integrally formed into the instrument panel body 13. In this way, by providing each of the instrument panel body 13 and the instrument panel cover 14 with a functional portion for suppressing the inflow of liquid into the opening 12, the instrument panel body 13 and the instrument panel cover 14 effectively achieve the function of suppressing the inflow of liquid into the opening 12 while being able to easily mold the instrument panel body 13 and the instrument panel cover 14.

[0051] In the present embodiment, the speaker installation opening 12 is a target opening from which liquid is to be suppressed from dripping. The speaker installation opening 12 is a relatively large opening among various openings provided in the instrument panel 1. Therefore, if liquid is spilled on the instrument panel 1, there is a concern that the liquid may flow into the speaker installation opening 12. However, the present embodiment includes a groove 15, a first step portion 16, and a second step portion 17 for suppressing liquid from flowing into the speaker installation opening 12. As a result, it is possible to suppress liquid from flowing into the speaker installation opening 12, and it is possible to suppress liquid from dripping into the interior of the instrument panel 1 through the speaker installation opening 12.

[0052] -Other Embodiments-

[0053] The present invention is not limited to the above-described embodiments, and all modifications and applications can be made within the scope of the claims and their equivalents.

[0054] For example, in the above embodiment, the case where the target opening for suppressing the dripping of liquid is the speaker mounting opening 12 has been described as an example. However, the present invention is not limited thereto but can be applied to other openings as the target opening for suppressing the dripping of liquid.

[0055] In the above embodiment, the groove 15 and the first step portion 16 are arranged on the inner side of the opening (speaker installation opening) 12 in the vehicle width direction. Instead of or in addition to this configuration, the present invention may have a configuration in which the groove and the first step portion are arranged on the outer side of the opening 12 in the vehicle width direction.

[0056] In the above-mentioned embodiment, the groove 15 extends in the front-rear direction of the vehicle. However, the extending direction is not limited thereto. The groove 15 may extend in a direction inclined toward the vehicle width direction at a predetermined angle relative to the front-rear direction of the vehicle. That is, the groove 15 of the present invention only needs to "extend in a direction intersecting the vehicle width direction".

[0057] The present invention is applicable to an instrument panel of a vehicle, which is configured to prevent a wiring harness or the like arranged in the instrument panel from being exposed to liquid.
