Description

[Technical field]

[0001] The present invention relates to an instrument panel for a vehicle. In particular, the present invention relates to a measure for suppressing dripping of liquid into the instrument panel when liquid is spilled on the instrument panel. In general, the instrument panel in the narrow sense means an instrument unit in front of the driver's seat, but the instrument panel in this specification means a part (including a part called a dashboard) arranged in the front part of the cabin of the vehicle from one end to the other end in the vehicle width direction (broad instrument panel). [Background technology]

[0002] Conventionally, a wire harness for supplying power and transmitting control signals to various electrical components mounted on the vehicle and a wire harness connector (hereinafter simply referred to as a connector) to which the wire harness is connected are arranged inside the instrument panel of a vehicle, as disclosed in, for example, Patent Document 1. Patent Document 1 discloses a configuration in which a wire harness is arranged between an upper instrument panel portion and a lower instrument panel portion that are divided into two parts, top and bottom. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 7-90731 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, an instrument panel is provided with various openings, such as an opening for attaching a speaker, etc. As described above, wire harnesses and connectors (hereinafter, these may be referred to as target parts) are arranged inside the instrument panel, and therefore target parts may also be arranged below the openings.

[0005] In such a configuration, if an occupant spills liquid on the instrument panel (for example, if a glass of water or a plastic bottle is knocked over), the liquid will flow down the upper surface of the instrument panel. This liquid will flow along the slope of the upper surface of the instrument panel, and if the opening is located somewhere along the slope, there is a risk that the liquid will flow into the opening and drip through the opening onto the target component. For this reason, measures to prevent the target components from being exposed to liquid are required. Note that target components for which measures to prevent exposure to liquid are required are not limited to the above-mentioned wire harnesses and connectors, but include various other components that may be defective if exposed to liquid.

[0006] As a measure to prevent the target parts from being exposed to liquid, it is possible to provide a liquid shielding plate or a drip-proof sheet individually above the target parts. In other words, a new liquid shielding plate or drip-proof sheet is fabricated and attached to the instrument panel etc. so as to be positioned above the target parts inside the instrument panel.

[0007] However, these measures would result in various problems, such as an increase in the number of parts, an increase in assembly work steps, a significant increase in the vehicle weight, and a rise in costs.

[0008] The present invention has been made in consideration of the above-mentioned points, and its object is to provide a vehicle instrument panel that can suppress liquid from dripping into the interior of the instrument panel, thereby avoiding the above-mentioned problems (problems that arise when a liquid-blocking plate or drip-proof sheet is installed). [Means for solving the problem]

[0009] The solution of the present invention for achieving the above object is based on an instrument panel for a vehicle, and is characterized in that the instrument panel includes a groove extending in a direction intersecting the vehicle width direction at a position at least toward one side in the vehicle width direction with respect to a position of an opening, and a restricting portion that restricts a flow of liquid toward the opening when the liquid flows into the groove and overflows from the groove.

[0010] With this feature, if an occupant spills liquid (e.g., water) on the instrument panel, the liquid will flow on the upper surface of the instrument panel. Then, when the liquid reaches the groove of the instrument panel, the liquid will flow along the groove. That is, the liquid will flow in a direction intersecting the vehicle width direction at a position closer to one side of the opening in the vehicle width direction (e.g., along the vehicle body front-rear direction). In this case, if the amount of spilled liquid is relatively large and overflows from the groove, the flow of the liquid toward the opening is restricted by the restricting portion. Therefore, the liquid is restricted from flowing into the opening, and the liquid is restricted from dripping through the opening into the inside of the instrument panel. Even if a target component (wire harness or connector) that needs to be prevented from being exposed to liquid is disposed below the opening inside the instrument panel, the liquid is restricted from dripping onto the target component. As described above, when a liquid shielding plate or a drip-proof sheet is individually provided above the target component as a measure to prevent the target component from being exposed to liquid, it is necessary to fabricate a new liquid shielding plate or drip-proof sheet and assemble it to the instrument panel or the like so that it is positioned above the target component inside the instrument panel. In contrast, the present solution prevents liquid from dripping inside the instrument panel, so there is no need to provide such a liquid shielding plate or drip-proof sheet. In other words, the present solution can prevent liquid from dripping onto the target component without increasing the number of parts or the number of assembly steps, and without causing a significant increase in the vehicle weight or a rise in costs.

[0011] In addition, a liquid guide portion is provided below the groove, which is inclined so as to guide the liquid that overflows from the groove in a direction intersecting the vehicle width direction, and the regulating portion is configured to include a first step portion that is continuous with a position in the liquid guide portion near the opening and extends upward, thereby regulating the flow of the liquid flowing through the liquid guide portion toward the opening.

[0012] As a result, the liquid spilling out of the groove is guided along the liquid guide in a direction intersecting the vehicle width direction. At this time, since a first step portion (restriction portion) is provided in the liquid guide portion in a position adjacent to the opening, the first step portion restricts the liquid flowing along the liquid guide portion from flowing toward the opening. This prevents the liquid from dripping into the interior of the instrument panel through the opening.

[0013] The restricting portion includes a second step portion that extends upward from the edge of the opening to restrict the flow of the liquid flowing along the upper surface of the instrument panel toward the opening.

[0014] As a result, even if liquid overflows from the groove and flows down the top surface of the instrument panel, the second step (restriction portion) is provided at the edge of the opening, so the second step prevents the liquid from flowing down the top surface of the instrument panel toward the opening. Even in this case, the liquid is prevented from dripping into the interior of the instrument panel through the opening.

[0015] The instrument panel further comprises an instrument panel main body and an instrument panel cover attached to the upper side of the instrument panel main body, the opening being formed in the instrument panel main body, the groove being integrally molded with the instrument panel cover, and the restricting portion being integrally molded with the instrument panel main body.

[0016] In this manner, when the instrument panel is composed of multiple components, each component is provided with a functional part for preventing liquid from flowing into the opening (a groove in the instrument panel cover and a regulating part in the instrument panel body), which makes it easy to mold each component while effectively preventing liquid from flowing into the opening.

[0017] The opening is a speaker mounting opening into which a speaker is fitted and mounted.

[0018] The speaker mounting opening is a relatively large opening among various openings provided in an instrument panel, and therefore, if liquid is spilled on the instrument panel, there is a concern that the liquid may flow into the speaker mounting opening. However, in this solution, by providing the groove and the restricting portion for preventing liquid from flowing into the speaker mounting opening, it is possible to prevent liquid from flowing into the speaker mounting opening and to prevent liquid from dripping into the interior of the instrument panel through the speaker mounting opening. Effect of the Invention

[0019] In the present invention, the instrument panel is provided with a groove extending in a direction intersecting the vehicle width direction at a position at least on one side of the vehicle width direction relative to the position of the opening of the instrument panel, and a restricting portion that restricts the flow of liquid toward the opening when liquid flows into the groove and overflows from the groove. This prevents liquid from dripping inside the instrument panel, making it unnecessary to provide a liquid shielding plate or a drip-proof sheet. In other words, the present invention can prevent liquid from dripping onto a target component disposed below the opening without increasing the number of components or the number of assembly steps, and without causing a significant increase in the vehicle weight or a rise in costs.

[Figure 4] FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a case where the present invention is applied to a configuration in which speakers are arranged on both sides in a vehicle width direction of an instrument panel of a vehicle will be described.

[0022] 1 is a view of the periphery of an instrument panel 1 of a vehicle according to this embodiment as seen from the rear of the vehicle. In Fig. 1, the arrow UP indicates the upward direction, the arrow RH indicates the right side in the vehicle width direction, and the arrow LH indicates the left side in the vehicle width direction.

[0023] As shown in Fig. 1, an instrument panel 1 is disposed in front of the driver's seat and the passenger seat. The instrument panel 1 is an interior member that covers the front of the driver's seat and the passenger seat, and is formed by laminating, for example, a base material, a cushioning material, a skin material, and the like. A center cluster 2 is disposed in the center of this instrument panel 1. A display 21 for car navigation and various switches are disposed in the center cluster 2. In addition, a steering wheel 3 is disposed in a position on the instrument panel 1 toward the right in the vehicle width direction.

[0024] Speaker units 4, 4 are disposed near both the left and right ends on the top surface of the instrument panel 1. The configuration around the location where the speaker unit 4 is disposed will be described below. Figure 2 is a cross-sectional view taken along line II-II in Figure 1. In Figure 2, the arrow UP indicates the upward direction, the arrow FR indicates the front of the vehicle, and the arrow RR indicates the rear of the vehicle.

[0025] In the cross-sectional portion shown in FIG. 2, the vehicle components appear as follows: a front windshield 5, a cowl 6, the instrument panel 1, the speaker unit 4, a speaker cover 7, and a wire harness 8 (the wire harness 8 is disposed within the area indicated by the square in the figure).

[0026] The front windshield 5 is disposed in front of the vehicle interior. The cowl 6 is formed to extend in the vehicle width direction and supports the lower end of the front windshield 5. A wire harness 8 for supplying power to and transmitting control signals to various electrical components mounted on the vehicle and a connector to which the wire harness 8 is connected are disposed in the internal space S of the instrument panel 1. In particular, in the case of an electric vehicle or a plug-in hybrid vehicle, the wire harness 8 may be a high-voltage one.

[0027] The instrument panel 1 has speaker mounting portions 11. The speaker mounting portions 11 are arranged at the front end of the instrument panel 1, and are provided at both ends in the vehicle width direction. The right and left speaker mounting portions 11 are configured to be substantially symmetrical.

[0028] An opening (hereinafter, sometimes referred to as a speaker mounting opening) 12 is formed in the speaker mounting portion 11, and the speaker unit 4 is fitted into this opening (speaker mounting opening) 12, and the speaker unit 4 is attached to the instrument panel 1. A speaker cover 7 is provided above the speaker unit 4 so as to cover the entire speaker mounting portion 11. The speaker cover 7 has a grill (not shown). In addition, a wire harness 8 and a connector (target parts) are disposed below the opening 12.

[0029] Next, the configuration of the periphery of the speaker mounting portion 11 in the instrument panel 1, which is a feature of this embodiment, will be described. Fig. 3 is a perspective view showing the periphery of the speaker mounting portion 11 in the instrument panel 1. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. In these figures, the arrow UP indicates the upward direction, the arrow RH indicates the right side in the vehicle width direction, and the arrow LH indicates the left side in the vehicle width direction. Fig. 3 shows a state in which the speaker cover 7 has been removed from the speaker mounting portion 11 located on the right side in the vehicle width direction. Therefore, in Fig. 3, the opening 12 of the speaker mounting portion 11 is visible.

[0030] As shown in Fig. 3, the instrument panel 1 includes an instrument panel body (hereinafter referred to as the instrument panel body) 13 made of resin, and an instrument panel cover (hereinafter referred to as the instrument panel cover) 14 attached (for example, attached by clips) to the upper side of the instrument panel body 13. Specifically, the instrument panel cover 14 is disposed on the inside in the vehicle width direction from a position where the speaker cover 7 is attached to the upper side of the instrument panel body 13. In addition, when the speaker cover 7 is attached to the upper side of the instrument panel body 13, the upper surface of the speaker cover 7 and the upper surface of the instrument panel cover 14 are configured to be flush with each other (see Fig. 1).

[0031] As described above, in a configuration in which a wire harness or a connector (target component) is disposed below an opening for mounting a speaker unit, if an occupant spills liquid on the instrument panel (for example, if a glass of water or a plastic bottle is knocked over), the liquid will flow down the upper surface of the instrument panel. The liquid will flow along the inclination of the upper surface of the instrument panel, and if an opening is present in the middle of the inclination, the liquid may flow into the opening and drip through the opening onto the target component. For this reason, measures to prevent the target component from being exposed to liquid are required. As a measure to prevent the target component from being exposed to liquid, it is possible to individually dispose a liquid shielding plate or a drip-proof sheet on the upper side of the target component. In other words, a new liquid shielding plate or drip-proof sheet is manufactured and attached to the instrument panel or the like so as to be positioned above the target component inside the instrument panel. However, these measures lead to various problems such as an increase in the number of components, an increase in the number of assembly steps, a significant increase in the vehicle weight, and a rise in costs.

[0032] In this embodiment, the instrument panel body 13 and the instrument panel cover 14 are provided with a functional part for preventing liquid from flowing into the opening 12, thereby making it possible to prevent the above-mentioned problem (problem when a liquid-shielding plate or a drip-proof sheet is provided) from occurring and to prevent liquid from dripping into the interior of the instrument panel 1 (dripping onto target components). Specifically, a groove 15 is integrally formed in the instrument panel cover 14, and a first step portion 16 and a second step portion 17 serving as regulating portions are integrally formed in the instrument panel body 13. A specific description will be given below.

[0033] A groove 15 extending along the vehicle body front-rear direction is formed at the outer end of the instrument panel cover 14 in the vehicle width direction. Specifically, the outer end of the instrument panel cover 14 in the vehicle width direction is provided with an inner vertical wall portion 15a extending in a substantially vertical direction (a direction substantially perpendicular to the vehicle width direction), a bottom plate portion 15b extending a predetermined dimension from the lower end of the inner vertical wall portion 15a toward the outside in the vehicle width direction, and an outer vertical wall portion 15c extending upward from the outer end of the bottom plate portion 15b in the vehicle width direction. The space surrounded by the inner vertical wall portion 15a, the bottom plate portion 15b, and the outer vertical wall portion 15c is formed as a groove 15 that is open upward and has a predetermined dimension along the vehicle body front-rear direction.

[0034] In addition, the upper surface of bottom plate portion 15b is an inclined surface that is inclined downward at a predetermined angle toward the inside of the vehicle compartment (the driver's seat and the passenger seat). Therefore, when liquid flows into groove 15, the liquid flows toward the inside of the vehicle compartment and flows out from the open end of groove 15 on the inside of the vehicle compartment (see dashed arrow A in FIG. 3).

[0035] The cross-sectional shape of the groove 15, which is determined by the height of the inner vertical wall portion 15a and the outer vertical wall portion 15c and the width of the bottom plate portion 15b (the dimension in the vehicle width direction), is appropriately set by experiments and simulations in consideration of the amount of liquid that is expected to be spilled by an occupant on the instrument panel. The cross-sectional shape of the groove 15 may be uniform or non-uniform over the entire extension direction of the groove 15.

[0036] In this embodiment, a flange portion 15d is provided at the upper end of the outer vertical wall portion 15c, and extends slightly outward in the vehicle width direction.

[0037] A liquid guide portion 18 is provided below the groove 15 in the instrument panel main body 13. This liquid guide portion 18 has a function of receiving the liquid when the amount of spilled liquid is relatively large and overflows from the groove 15. The upper surface of this liquid guide portion 18 is an inclined surface that inclines downward toward the inside of the vehicle compartment (driver's seat and passenger seat). This inclined surface includes a front inclined surface 18a located at the front of the vehicle and having a relatively small inclination angle, and a rear inclined surface 18b that is continuous with the end of the front inclined surface 18a on the inside of the vehicle compartment and has a relatively large inclination angle. The configuration of the inclined surface in the liquid guide portion 18 is not limited to this, and may have a uniform inclination angle over the entire surface, or may have three or more inclined surfaces with different inclination angles.

[0038] Because such a liquid guide portion 18 is provided, when liquid overflows from groove 15 and flows down onto the upper surface of liquid guide portion 18 (see dashed arrow B in Figure 3), the liquid will flow along liquid guide portion 18 toward the inside of the vehicle cabin (see dashed arrow C in Figure 3).

[0039] The instrument panel body 13 is provided with the first step portion 16 that extends upward and is continuous with the outer end portion (position closer to the opening) of the liquid guide portion 18 in the vehicle width direction. The first step portion 16 has a function of restricting the liquid flowing through the liquid guide portion 18 from flowing toward the opening 12.

[0040] Specifically, the first step portion 16 is set in advance by experiments and simulations as a height dimension that the liquid level of the liquid flowing along the liquid guide portion 18 will not exceed (exceed the upper end position of the first step portion 16) even in a situation where a relatively large amount of spilled liquid is present. Specifically, the first step portion 16 includes a front step portion 16a (located outside the front step portion 18a) corresponding to the front inclined surface 18a of the liquid guide portion 18, and a rear step portion 16b (located outside the rear inclined surface 18b) corresponding to the rear inclined surface 18b of the liquid guide portion 18. The respective height dimensions of the front step portion 16a and the rear step portion 16b are set in advance to dimensions that the liquid level of the liquid flowing along the liquid guide portion 18 will not exceed even in a situation where a relatively large amount of spilled liquid is present.

[0041] The instrument panel body 13 is provided with the second step portion 17, which extends upward from the edge of the opening 12 facing the interior of the vehicle. The second step portion 17 is continuous with the first step portion 16 on the outer side in the vehicle width direction, and has a function of restricting liquid flowing on the upper surface of the instrument panel 1 (see the dashed arrow D in FIG. 3 ) from flowing toward the opening 12.

[0042] Specifically, the second step portion 17 includes a front-rear step portion 17a extending substantially along the front-rear direction of the vehicle body (extending in a direction substantially perpendicular to the vehicle width direction) and a left-right step portion 17b extending substantially along the vehicle width direction (extending in a direction substantially perpendicular to the front-rear direction of the vehicle body) continuing from an end portion of the front-rear step portion 17a on the passenger compartment side. The height dimensions of the front-rear step portion 17a and the left-right step portion 17b are set in advance through experiments and simulations as height dimensions that the liquid level of the liquid flowing on the upper surface of the instrument panel 1 will not exceed (exceed the upper end position of the second step portion 17) even in a situation where a relatively large amount of spilled liquid is present.

[0043] Next, a description will be given of the flow of liquid when an occupant spills liquid on the instrument panel 1. In this case, the liquid flows along the upper surface of the instrument panel 1 (for example, the upper surface of the instrument panel cover 14). If the amount of spilled liquid is relatively small, when the liquid reaches the groove 15 provided in the instrument panel cover 14, the liquid flows along the groove 15. In other words, 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 dashed arrow A in FIG. 3).

[0044] On the other hand, if the amount of spilled liquid is relatively large and the liquid overflows from groove 15 and flows down onto the upper surface of liquid guide portion 18 (see dashed arrow B in FIG. 3), the liquid will flow along liquid guide portion 18 toward the inside of the vehicle compartment (see dashed arrow C in FIG. 3). At this time, because first step portion 16 is provided continuously with the outer end portion (position closer to opening 12) of liquid guide portion 18 in the vehicle width direction, the liquid flowing through liquid guide portion 18 is restricted from flowing toward opening 12.

[0045] Furthermore, in the event that the liquid flows along the upper surface of the instrument panel main body 13 after flowing along the liquid guide portion 18 (see dashed arrow D in Figure 3), a second step portion 17 is provided on the edge of the opening 12 facing the interior of the vehicle, so that the liquid flowing along the upper surface of the instrument panel main body 13 is restricted from flowing toward the opening 12.

[0046] As described above, in this embodiment, the instrument panel 1 is provided with the groove 15 extending in a direction intersecting the vehicle width direction at a position closer to one side in the vehicle width direction with respect to the position of the opening 12 of the instrument panel 1, and the first step portion 16 and the second step portion 17 as a restricting portion that restricts the flow of the liquid toward the opening 12 when the liquid flows into the groove 15 and overflows from the groove 15. This prevents the liquid from dripping inside the instrument panel 1, so there is no need to provide a liquid shielding plate or a drip-proof sheet. In other words, in this embodiment, it is possible to prevent the liquid from dripping onto the target components (wire harness 8 and connector) arranged below the opening 12 without increasing the number of parts or the number of assembly steps, and without causing a significant increase in the vehicle weight or a rise in costs.

[0047] In this embodiment, the groove 15 is integrally formed in the instrument panel cover 14, and the first step portion 16 and the second step portion 17 are integrally formed in the instrument panel body 13. In this manner, by providing each of the instrument panel cover 14 and the instrument panel body 13 with a functional portion for preventing liquid from flowing into the opening 12, it is possible to effectively perform the function of preventing liquid from flowing into the opening 12 while facilitating the molding of each of the instrument panel cover 14 and the instrument panel body 13.

[0048] In this embodiment, the opening into which liquid is not to be dripped is the speaker mounting opening 12. The speaker mounting opening 12 is a relatively large opening among various openings provided in the instrument panel 1. For this reason, if liquid is spilled on the instrument panel 1, there is a concern that the liquid will flow into the speaker mounting opening 12. However, in this embodiment, by providing the groove 15, the first step portion 16, and the second step portion 17 for preventing the liquid from flowing into the speaker mounting opening 12, it is possible to prevent the liquid from flowing into the speaker mounting opening 12 and to prevent the liquid from dripping into the inside of the instrument panel 1 through the speaker mounting opening 12.

[0049] -Other embodiments- The present invention is not limited to the above-described embodiment, and all modifications and applications within the scope of the claims and equivalents thereto are possible.

[0050] For example, in the above embodiment, the opening into which liquid is not to be dripped is the speaker mounting opening 12. The present invention is not limited to this, and other openings can be used as openings into which liquid is not to be dripped.

[0051] In the above embodiment, the groove 15 and the first step 16 are disposed on the inside in the vehicle width direction of the opening (speaker mounting opening) 12. Instead of or in addition to this, the present invention may be configured such that the groove and the first step are disposed on the outside in the vehicle width direction of the opening 12.

[0052] In the above embodiment, the groove 15 extends along the vehicle body front-rear direction, but the extension direction is not limited to this, and the groove may extend at a predetermined angle in the vehicle width direction with respect to the vehicle body front-rear direction. In other words, it is sufficient that the groove "extends in a direction intersecting the vehicle width direction" as defined in the present invention. [Industrial Applicability]

[0053] The present invention is applicable to an instrument panel of a vehicle that can prevent liquid from being applied to a wire harness or the like arranged inside the instrument panel. [Explanation of symbols]
