Description

[Technical Field]

[0001] This invention relates to a front structure of a vehicle, and more particularly to a front structure of a vehicle that includes a dash panel that extends in the vehicle width direction and separates an engine compartment from a passenger compartment in the fore-and-aft direction of the vehicle, a suspension housing to which suspension members are attached in front of the dash panel, and a partition wall that separates the space between the dash panel and the suspension housing into front and rear sections. [Background technology]

[0002] Conventionally, a known structure is one in which a partition wall is provided at the rear of the suspension housing to separate the engine compartment in front of the dash panel in the fore-and-aft direction of the vehicle, and auxiliary equipment that is vulnerable to heat damage, such as brake system units such as a master cylinder and a brake booster, and battery system units such as a battery, are placed in the space behind this partition wall.

[0003] In such a structure, it is necessary to provide a through-hole in the partition wall so that wiring members such as pipes and harnesses can be connected to the auxiliary equipment located in the space behind the partition wall. In this case, in order to reliably isolate the hot zone in front of the partition wall from the cool zone behind the partition wall, a structure can be considered in which a sealing member is provided on the inner periphery of the through hole, and this sealing member seals between the outer periphery of the wiring member and the inner periphery of the through hole.

[0004] However, because the sealing member is soft, if the wiring member is misaligned, a gap will occur and proper sealing will not be achieved. Specifically, when wiring a harness that has low rigidity and flexibility as the wiring member, it is advisable to provide a sealing member on the inner periphery of the through hole and insert the harness into the insertion hole of this sealing member, even if the positional relationship is slightly misaligned.

[0005] On the other hand, when installing a steel pipe, which is highly rigid but not flexible, as a wiring member and sealing the pipe with a sealing member around the inner periphery of the through hole, the pipe needs to be fitted accurately into the through hole, and if the pipe is misaligned, distortion occurs and gaps are created, making it impossible to achieve proper sealing.

[0006] Incidentally, Patent Document 1 discloses a cowl grille that includes a cover that covers the top of the battery and a cowl seal at the front end of the cover, but does not disclose at all about the sealing structure between the cover and the wiring member.

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2018-43602 Summary of the Invention [Problem to be solved by the invention]

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a front structure for a vehicle that can achieve both the positioning of a wiring member and the securing of sealing properties of an insertion portion provided in a partition wall. [Means for solving the problem]

[0009] The present invention provides a vehicle body comprising: a dash panel extending in the vehicle width direction and separating an engine compartment from a passenger compartment in the vehicle longitudinal direction; a suspension housing to which a suspension member is attached in front of the dash panel; a partition wall separating a space between the dash panel and the suspension housing into front and rear sections; a wiring member inserted into an insertion portion provided in the partition wall; and a support member supporting the wiring member and fixed to the vehicle body, the support member having a fixing portion for fixing the wiring member and supporting a seal member at a position adjacent to the fixing portion in the longitudinal direction, the seal member clamping the wiring member in cooperation with the insertion portion of the partition wall. The seal member has a first seal portion that contacts the wiring member and a second seal portion that contacts the vehicle body member and has lower rigidity than the first seal portion.The front structure of a vehicle is characterized by: The wiring members mentioned above are members such as steel pipes, electrical harnesses, signal transmission / reception harnesses, and cables.

[0010] With this invention, the wiring member is supported on the support member, so the position of the wiring member that passes through the insertion portion of the partition wall is specified, and the positional relationship between the sealing member and the wiring member can be set to a specified value, thereby ensuring sealing performance. In short, it is possible to achieve both the positioning of the wiring member and the sealing performance of the insertion portion provided in the partition wall.

[0011] Also , As mentioned above, The seal member has a first seal portion that contacts the wiring member, and a second seal portion that contacts the vehicle body member and has lower rigidity than the first seal portion. R . The above-mentioned vehicle body member may be an apron reinforcement and a suspension housing.

[0012] child Re This makes it possible to achieve both positioning of the wiring member and ensuring sealing between the support member and the vehicle body member with a simple configuration. In detail, the first seal portion, which has higher rigidity than the second seal portion, ensures both sealing performance and positional control of the routing member, while the second seal portion, which has lower rigidity than the first seal portion, ensures a reliable seal between the body member and the support member.

[0013] In one aspect of the present invention, the sealing member has a recess formed in it that matches the shape of the routing member, and the opening direction of the recess may coincide with the mounting direction of a fixing member that fixes the routing member to the fixing portion of the support member.

[0014] The present invention provides the following effects. In other words, if the routing member gets caught in the sealing member when assembling the routing member, a gap will occur between the sealing member and the routing member. However, as described above, the opening direction of the recess and the installation direction of the fixing member are aligned, so the occurrence of such a gap can be suppressed, and the breakage of the sealing member can also be suppressed.

[0015] As an aspect of the present invention, the routing member may be provided with a peripheral seal member at a portion that comes into contact with the seal member. According to this invention, the sealing performance of the outer peripheral seal member can be further improved.

[0016] In one aspect of the present invention, the support members may be configured as a pair of left and right support members that are symmetrical, and the seal member may have a third seal portion that is configured to be less rigid than the first seal portion, located opposite the partition wall around the recess of the first seal portion.

[0017] According to this invention, when the support member and sealing member are arranged on both the left and right sides of the vehicle, the third sealing portion deforms to seal even in areas where there is no recess in the first sealing portion, so a sealing structure can be constructed using left and right symmetrical support members even if there is or is not routing members on the left and right sides of the vehicle.

[0018] In one aspect of the present invention, the routing member has a high-rigidity routing member and a low-rigidity routing member, the sealing member is fixed to the upper surface of the bottom portion of the support member extending along the vehicle body, the opposing surface of the sealing member facing the partition wall is inclined upward as it moves outward in the vehicle width direction, and a high-rigidity routing member is arranged on the inner side of the opposing surface in the vehicle width direction, and a low-rigidity routing member is arranged on the outer side of the opposing surface in the vehicle width direction. The wiring member with high rigidity may be set to a pipe made of steel pipe, and the wiring member with low rigidity may be set to a harness.

[0019] This invention allows the wiring members that require positional regulation to be positioned on the inner side in the vehicle width direction, where the distance from the bottom is small, and the wiring members that require a larger tolerance for positional regulation can be positioned on the outer side in the vehicle width direction, where the distance from the bottom is large, and allows multiple wiring members with different rigidities to be properly routed. [Effects of the Invention]

[0020] According to this invention, it is possible to achieve both the positioning of the wiring member and the ensuring of the sealing performance of the insertion portion provided in the partition wall. [Brief explanation of the drawings]

[0032] The front side frame 11 described above is a vehicle body strength member having a front side frame inner and a front side frame outer joined and fixed together, and having a front side frame closed cross section extending in the longitudinal direction of the vehicle.

[0033] As shown in FIG. 1, a set plate 12 having a substantially flat shape is provided at the front end of the front side frame 11, and a crash can serving as a collision energy absorbing member is attached to the set plate 12 via an attachment plate.

[0034] As shown in FIG. 1, the outer ends of the corner members 9 and shroud upper 10 in the vehicle width direction are connected to the front ends of the front side frames 11 by connecting members 13 extending in the vertical direction.

[0035] 1 and 5, a suspension housing 14 to which a suspension member, more specifically a damper of a front suspension device, is attached is provided in front of the dash lower panel 3. As shown in FIGS. 1 and 5, this suspension housing 14 is attached between the flange portion 6b of the apron reinforcement lower 6 and the front side frame 11, and is formed so as to protrude upward from the front side frame 11.

[0036] As shown in Figure 9, the flange portion 6b of the apron reinforcement lower 6 and the outer portion of the upper end of the suspension housing 14 in the vehicle width direction are connected and fixed by multiple rivets RV (however, for convenience of illustration, only one rivet RV is shown in the drawing).

[0037] As shown in Fig. 1, a cowl panel 16 having a generally hat-shaped cross section is attached to the upper bent portion 3a of the dash lower panel 3 via a dash upper panel 15. A closed cowl cross section 17 extending in the vehicle width direction is formed between the cowl panel 16 and the dash upper panel 15 to improve the rigidity of the cowl portion. A floor panel (not shown) is connected to the lower bent portion 3b of the dash lower panel 3.

[0038] A front windshield (not shown) is attached to the upper wall portion of the cowl panel 16, which slopes low at the front and high at the rear, with an adhesive. As shown in FIG. 1, below the front windshield (in this embodiment, below the inclined front windshield) there is provided a cowl grill 18 located above the dash lower panel 3 and in the front of the vehicle.

[0039] This cowl grille 18 is provided with a member portion 19 that extends in the vehicle width direction below the front windshield and receives water dripping from the front windshield, and left and right cover portions 20 (only the cover portion 20 on the right side of the vehicle is shown in the drawing) that are located in front of the member portion 19 and cover the upper parts of the auxiliary equipment (see fuse box case 21 shown in Figure 3) described below.

[0040] The cover portion (not shown) on the left side of the vehicle covers the top of a reservoir tank (not shown) as an auxiliary device located below it, and the cover portion 20 on the right side of the vehicle covers the top of a fuse box case 21 (see Figure 3) as an auxiliary device located below it.

[0041] As shown in FIG. 3, the case 21 of the fuse box described above is supported by a support pin 23 that protrudes toward the inside in the vehicle width direction from a side panel 22 that covers the space between the front part of the outer end of the dash lower panel 3 in the vehicle width direction and the inside in the vehicle width direction at the rear part of the apron reinforcement 4.

[0042] As shown in Figure 1, the cowl grill 18 described above comprises the member portion 19, the cover portion 20, a partition wall 25 and a side partition wall 26 extending downward from the cover portion 20 to separate the engine room 1, which is the space on the engine side, from the auxiliary equipment arrangement space 24 (see Figure 6), which is the space on the auxiliary equipment side, and a cowl seal (not shown) extending in the vehicle width direction and contacting the hood (more specifically, the hood inner panel) to seal between the space outside the vehicle and the engine room 1.

[0043] The partition wall 25 divides the space between the dash lower panel 3 and the suspension housing 14 into front and rear sections. In other words, the partition wall 25 is a wall member that divides the engine compartment 1 and the auxiliary equipment arrangement space 24 in the front-rear direction of the vehicle.

[0044] As shown in FIG. 1, the member portion 19 of the cowl grille 18 includes an upper wall portion 19a extending in the vehicle width direction and the vehicle front-to-rear direction, and a front vertical wall portion 19b and a rear vertical wall portion 19c extending downward from the front and rear ends of the upper wall portion 19a via the front corners and rear corners. As shown in FIG. 1, an air introduction hole 19d having a mesh structure is formed at the rear side in the front-rear direction of the upper wall portion 19a of the member portion 19 in the middle portion in the vehicle width direction.

[0045] The cover portion 20 is made of a plate-shaped member and is arranged to separate the space above the cover portion 20 from the space below the cover portion 20, which is the auxiliary equipment arrangement space 24.

[0046] As shown in FIG. 2, the cover portion 20 includes a cover body 20a that covers the upper side of the auxiliary equipment arrangement space 24. As shown in FIG. A flange portion 20c extending in the longitudinal direction of the vehicle is integrally formed on the front portion of the cover main body 20a via a skirt portion 20b extending in the vertical direction.

[0047] 1 and 2, the cover body 20a of the cover part 20 has a non-porous structure with no holes, and the upper surface of the cover body 20a is configured to be smooth and substantially flat, thereby ensuring the rigidity of the cover part 20 compared to a cover part with a perforated structure.

[0048] In this embodiment, as shown in FIG. 1, there is provided a drainage member 27 that covers the underside of the member portion 19 of the cowl grille 18 and extends in the longitudinal direction of the vehicle and in the width direction of the vehicle, a rear partition portion 28 that is spaced forward from the dash lower panel 3 and covers the front of the dash lower panel 3, and an upper partition portion 29 that extends in the width direction of the vehicle and covers the area between the front lower surface of the drainage member 27 and the front upper surface of the upper end bent portion of the rear partition portion 28. The drainage member 27 is a member that receives dripping water and guides it downward outward in the vehicle width direction.

[0049] As shown in Figures 2, 9 and 10, the above-mentioned partition wall 25 comprises a partition wall main body 25a, an upper flange portion 25b located at the upper end of the partition wall main body 25a, and a lower flange portion 25c located at the lower end of the partition wall main body 25a.

[0050] As shown in Figures 2 and 9, the lower flange portion 25c has a lower side portion 25d extending in the vehicle width direction at the bottom, a vertical side portion 25e rising upward from the outer side of the lower side portion 25d in the vehicle width direction, and an inclined side portion 25f extending outward in the vehicle width direction from the upper end of the vertical side portion 25e and inclining upward as it moves further outward in the vehicle width direction.

[0051] As shown in Figure 9, an outer edge portion 25g is provided that extends further outward in the vehicle width direction from the outer end of the above-mentioned inclined edge portion 25f in the vehicle width direction, and the outer edge portion 25g of the partition wall 25 is placed on the upper wall 5a of the apron reinforcement upper 5, as shown in the same figure.

[0052] As shown in FIG. 10, the outer periphery 25g is formed so as to be stepped down on the outer side in the vehicle width direction relative to the upper flange 25b. As shown in Fig. 2, the upper flange portion 25b of the partition wall 25 is connected and fixed to the flange portion 20c of the cover portion 20 by an attachment member 30 such as a clip. Although Fig. 2 shows only one attachment member 30, in reality, a plurality of attachment members 30 are used to connect and fix the above-mentioned two members 25b and 20c.

[0053] 9, a plurality of insertion portions 25A, 25B, and 25C are provided on the inclined side portion 25f of the partition wall 25. Each of these insertion portions 25A, 25B, and 25C is spaced apart from the adjacent insertion portions in the vehicle width direction.

[0054] The insertion portion 25A located on the outer side of the inclined side portion 25f in the vehicle width direction is a portion through which a wire harness 31 such as a front harness is inserted. The insertion portion 25B located on the middle portion between the inside and outside of the inclined side portion 25f in the vehicle width direction is a portion through which a pipe 32 such as a high-pressure cooler pipe is inserted. The insertion portion 25C located on the inner side of the inclined side portion 25f in the vehicle width direction is a portion through which a pipe 33 such as a brake vacuum pipe is inserted.

[0055] As shown in the cross-sectional view of Figure 9, the above-mentioned wire harness 31 comprises an insulating coating 31a that covers the internal electric wires (not shown) and an outer casing material 31b that is provided on the outer periphery of this insulating coating 31a, and an outer periphery seal member 34 is provided at a position corresponding to the insertion portion 25A.

[0056] The above-mentioned exterior material 31b protects the electric wires, and for example, a corrugated exterior material is used as this exterior material 31b. A vinyl tape (not shown) is continuously wound from the outer periphery of the exterior material 31b to the outer periphery of the insulating coating 31a between the front portion of the exterior material 31b located on the inner periphery of the outer sealing member 34 and the insulating coating 31a just before it, and between the rear portion of the exterior material 31b and the insulating coating 31a just after it. This prevents gaps from occurring due to the difference in outer diameter between the exterior material 31b and the insulating coating 31a.

[0057] The pipe 32 has an exterior material 32a at least at a position corresponding to the insertion portion 25B. The pipe 33 is formed of, for example, a steel pipe.

[0058] Similarly to the above, vinyl tape (not shown) may be continuously wrapped between the front of the exterior material 32a and the pipe 32 immediately in front of it, and between the rear of the exterior material 32a and the pipe 32 immediately behind it, to prevent gaps from occurring due to the difference in outer diameter between the exterior material 32a and the pipe 32.

[0059] As shown in FIG. 9, the insertion portions 25B and 25C through which the pipes 32 and 33 are inserted are formed in an inclined and linear shape that is lower on the inside in the vehicle width direction and higher on the outside in the vehicle width direction, while the insertion portion 25A through which the wire harness 31 is inserted is formed in an arc shape that faces inward and upward in the vehicle width direction. The above-mentioned wire harness 31 and pipes 32 and 33 are wiring members that are inserted into insertion portions 25A, 25B, and 25C provided in the partition wall 25.

[0060] As shown in FIGS. 4, 5, 8, 10 and 11, a metal bracket 40 is provided as a support member that supports the wiring harness 31 and pipes 32 and 33 as wiring members and is fixed to the vehicle body.

[0061] As shown in Figure 11, this bracket 40 has an intermediate side portion 40a located midway between the inside and outside in the vehicle width direction, an outer side portion 40b formed in a stepped-down position on the outside of this intermediate side portion 40a in the vehicle width direction, and an inner side portion 40c formed in a stepped-down position on the inside of the above-mentioned intermediate side portion 40a in the vehicle width direction.

[0062] The above-mentioned intermediate side portion 40a, outer side portion 40b, and inner side portion 40c are formed to be substantially flat. Furthermore, the bracket 40 has a bottom surface portion 40e connected to the vehicle front side of the intermediate side portion 40a via a connecting portion 40d. As shown in Fig. 5, this bottom surface portion 40e has a horizontal portion 40f extending in the vehicle width direction along the flange portion 5d of the upper apron reinforcement 5 and the flange portion 6b of the lower apron reinforcement 6, and a slant portion 40g located downward in the vehicle width direction from the inner end of the horizontal portion 40f in the vehicle width direction toward the inside.

[0063] As shown in FIGS. 2, 6 and 9, the bottom surface 40e of the bracket 40 overlaps the lower flange portion 25c of the partition wall 25 in the vertical direction. As shown in FIGS. 5 and 8, the inner side portion 40c of the bracket 40 is fixed to the upper portion of the suspension housing 14 by a fastening member 41 such as a bolt.

[0064] As shown in Figure 11, anchor holes 40h for attaching clamps 42 (see Figure 10) are formed in the middle side 40a of bracket 40. Furthermore, anchor holes 40i for attaching clamps 43 (see Figure 10) are formed in the outer side 40b of bracket 40. Furthermore, bolt insertion holes 40j for inserting the above-mentioned fastening members 41 are formed in the inner side 40c of bracket 40. Here, the above-mentioned anchor holes 40h are formed in the shape of elongated holes that are long in the vehicle width direction, and the above-mentioned anchor holes 40i are formed in the shape of elongated holes that are long in the vehicle front-rear direction.

[0065] As shown in Figure 10, the clamp 42 that holds the pipe 32 and fixes it to the bracket 40 has a pipe holding portion 42a, a locking portion 42b, and an anchor portion 42c, and the pipe 32 is fixed to the bracket 40 by engaging the anchor portion 42c with the anchor hole 40h of the bracket 40.

[0066] As shown in Figure 10, the clamp 43 that holds the wire harness 31 and fixes it to the bracket 40 has a band 43a as a belt-shaped member, a buckle portion 43b that engages the band 43a, and an anchor portion 43c, and is a so-called band clamp that fixes the wire harness 31 to the bracket 40 by engaging the anchor portion 43c with the anchor hole 40i of the bracket 40. In this manner, the bracket 40 as a support member has the anchor holes 40i and 40h as fixing portions for fixing the wiring members (wire harness 31, pipe 32).

[0067] As shown in Figures 4 and 5, the sealing member 50 is supported at a position adjacent to the anchor holes 40h and 40i in the front-to-rear direction, i.e., at the bottom surface portion 40e located immediately before the middle edge portion 40a and the outer edge portion 40b of the bracket 40.

[0068] As shown in FIG. 9, the sealing member 50 cooperates with the insertion portions 25A, 25B, and 25C of the partition wall 25 to sandwich the wiring harness 31 and the pipes 32 and 33 as wiring members from above and below.

[0069] As a result, the wire harness 31 and the pipes 32, 33 (particularly the wire harness 31 and the pipe 32) are supported by the bracket 40, so that the positions of the wire harness 31 and the pipes 32, 33 that pass through the insertion portions 25A, 25B, 25C of the partition wall 25 are regulated, and the positional relationship between the sealing member 50 and the wire harness 31 and the pipes 32, 33 can be set to a specified value, thereby ensuring sealing performance. That is, the configuration is such that the positioning of the wire harness 31 and the pipes 32 and 33 is achieved while ensuring the sealing performance of the insertion portions 25A, 25B, and 25C provided in the partition wall 25.

[0070] As shown in Figures 4 and 9, the above-mentioned sealing member 50 has a main sealing portion 51 (first sealing portion) that rises upward from the bottom portion 40e of the bracket 40 toward the inclined side portion 25f of the partition wall 25 and contacts the wire harness 31 and pipes 32, 33, and a lower sealing portion 52 (second sealing portion) and a side sealing portion 53 (second sealing portion) that contact the vehicle body members and are configured to have lower rigidity than the main sealing portion 51.

[0071] The main seal portion 51 provides a seal between the wire harness 31, pipes 32, 33, and the upper surface of the bottom portion 40e. The lower seal portion 52 provides a seal between the lower surface of the bottom portion 40e and each of the flange portions 5d, 6b and the rib flange 14a of the suspension housing 14. The side seal portion 53 provides a seal between the outer end face of the main seal portion 51 in the vehicle width direction and the inner side wall 5b of the upper apron reinforcement 5.

[0072] As shown in Figure 8, the above-mentioned rib flange 14a is provided on the upper part of the suspension housing 14 and is a protrusion formed by protruding upward from the reference upper surface 14b of the suspension housing 14 around the periphery of the rib flange 14a to a position adjacent to the lower surface of the slant portion 40g of the bracket 40.

[0073] As described above, the sealing member 50 has a main sealing portion 51 that contacts the wire harness 31 and pipes 32, 33, and a lower sealing portion 52 and a side sealing portion 53 that contact the vehicle body member and have lower rigidity than the main sealing portion 51, so that the simple structure can both position the wiring member and ensure sealing between the bracket 40 and the vehicle body member.

[0074] In detail, the main seal portion 51 has higher rigidity than the lower seal portion 52 and the side seal portion 53, thereby ensuring both sealing performance and regulating the position of the wiring member, and the lower seal portion 52 and the side seal portion have lower rigidity than the main seal portion 51, thereby reliably sealing between the vehicle body member and the bracket 40 or the main seal portion 51.

[0075] As shown in FIG. 9, a main seal portion 51 of a seal member 50 is formed with recesses 51a and 51b that fit the shapes of the wire harness 31 and the pipe 32, respectively. The recess 51a corresponding to the wire harness 31 is formed in a recessed shape that matches the shape of the outer periphery seal member 34 located on the outer periphery of the exterior material 31b when sealed. The recess 51b corresponding to the pipe 32 is formed in a recessed shape that matches the outer peripheral shape of the exterior material 32a.

[0076] As shown in Figure 9, the opening direction (inward and upward in the vehicle width direction) of the above-mentioned recesses 51a, 51b coincides with the mounting direction of the clamps 43, 42 (see Figure 10) of the wire harness 31 and pipe 32 to the anchor holes 40i, 40h (see Figure 11) of the bracket 40.

[0077] Specifically, as shown in Figure 9, the direction L1 (orthogonal direction) perpendicular to the outer edge portion 40b is the mounting direction of the anchor portion 43c in the clamp 43, and the direction extending from the center of the bottom of the recess 51a toward the middle of the upper end opening of the recess 51a coincides with the orthogonal direction L1.

[0078] Similarly, as shown in Figure 9, the direction L2 (orthogonal direction) perpendicular to the intermediate side portion 40a is the mounting direction of the anchor portion 42c in the clamp 42, and the direction extending from the center of the bottom of the recess 51b toward the middle of the upper end opening of the recess 51b coincides with the orthogonal direction L2.

[0079] That is, the recesses 51 a and 51 b of the main seal portion 51 are formed so as to be perpendicular to the outer side portion 40 b and the middle side portion 40 a of the bracket 40 .

[0080] As a result, if the wiring components are caught in the edges of the upper openings of the recesses 51a, 51b of the main seal portion 51 when the wire harness 31 and the pipe 32 are assembled, a gap will be created between the main seal portion 51 and the wiring components. However, as described above, by aligning the opening direction of the recesses 51a, 51b with the mounting direction of the anchor portions 43c, 42c of the clamps 43, 42, the creation of such a gap is suppressed and the breakage of the main seal portion 51 is also suppressed.

[0081] 2, 6, and 7, an outer circumferential seal member 34 is provided at a portion of the wiring member where the wire harness 31 contacts the seal member 50 (more specifically, the main seal portion 51) in the longitudinal direction of the wire harness 31. This allows the outer circumferential seal member 34 to further improve sealing performance.

[0082] The brackets 40 are provided on the right and left sides of the vehicle, and are configured symmetrically in a pair, although only the bracket 40 provided on the right side of the vehicle is shown in the drawings.

[0083] As shown in Figure 9, the upper periphery of the recesses 51a, 51b of the main seal portion 51 of the seal member 50 faces the lower flange portion 25c of the partition wall 25, and is provided with an upper seal portion 54 (third seal portion) that is configured to have lower rigidity than the main seal portion 51.

[0084] In this embodiment, as shown in FIG. 2, the upper seal portion 54 is provided so as to be continuous from the inclined side portion 25f through the vertical side portion 25e to the inner end of the lower side portion 25d in the vehicle width direction.

[0085] When the above-mentioned bracket 40 and sealing member 50 are arranged on both the left and right sides of the vehicle, the upper sealing portion 54 deforms to seal even in areas where the recesses 51a, 51b of the main sealing portion 51 do not exist (areas corresponding to the insertion portion 25C).Therefore, even if there are wiring members, such as brake vacuum pipes, on both the left and right sides of the vehicle, a sealing structure can be formed using a bracket 40 with a left-right symmetrical structure.

[0086] In this embodiment, the brake vacuum pipe (see pipe 33) is routed only on the right side of the vehicle, and not on the left side. Even if the brake vacuum pipe is not routed on the left side of the vehicle, the upper surface of main seal portion 51 and the lower surface of upper seal portion 54 abut against each other, so that sealing at insertion portion 25C is reliably performed and sealing performance is ensured. The above-mentioned wiring member includes the pipe 33, which is a wiring member having a relatively high rigidity, and the wire harness 31, which is a wiring member having a relatively low rigidity.

[0087] 9, the main seal portion 51 of the sealing member 50 is fixed to the upper surface of the bottom surface portion 40e of the bracket 40, which extends along the vehicle body. The main seal portion 51 has an opposing surface 51A that faces the inclined side portion 25f of the partition wall 25, and the opposing surface 51A is inclined upward toward the outer side in the vehicle width direction.

[0088] A pipe 33, which is a wiring member with relatively high rigidity, is arranged on the inner side of the opposing surface 51A in the vehicle width direction, and a wire harness 31, which is a wiring member with relatively low rigidity, is arranged in a recess 51a on the outer side of the opposing surface 51A in the vehicle width direction.

[0089] This allows the pipe 33, which requires positional regulation, to be positioned on the inner side in the vehicle width direction where the distance from the bottom surface 40e is small, thereby ensuring the positioning of the pipe 33. Also, the wire harness 31, which has a large tolerance for positional regulation, can be positioned on the outer side in the vehicle width direction where the distance from the bottom surface 40e is large, and is configured to allow a plurality of wiring members with different rigidities to be properly routed.

[0090] 9, the wire harness 31 including the outer casing 31b is sealed at the insertion portion 25A between the upper seal portion 54 and the main seal portion 51 with the outer periphery seal member 34 provided on the outer periphery of the outer casing 31b. As shown in the same figure, the pipe 32 including the outer casing 32a is sealed at the insertion portion 25B between the upper seal portion 54 and the main seal portion 51. Furthermore, the pipe 33 is sealed at the insertion portion 25C between the upper seal portion 54 and the main seal portion 51. Furthermore, on the left side of the vehicle where the pipe 33 is not routed, the insertion portion 25C is sealed by the abutment between the lower surface of the upper seal portion 54 and the upper surface of the main seal portion 51.

[0091] It should be noted that an EPDM (ethylene-propylene copolymer) foam seal material may be used for the above-mentioned outer circumferential seal member 34, lower seal portion 52, side seal portion 53, and upper seal portion 54. In the drawing, arrow F indicates the front of the vehicle, arrow R indicates the rear of the vehicle, arrow IN indicates the inward direction in the vehicle width direction, arrow OUT indicates the outward direction in the vehicle width direction, and arrow UP indicates the upward direction of the vehicle.

[0092] As described above, the front structure of the vehicle according to this embodiment includes the dash panel (dash lower panel 3) extending in the vehicle width direction and separating the engine compartment 1 and the passenger compartment 2 in the vehicle longitudinal direction, the suspension housing 14 to which the suspension members (see damper) are attached in front of the dash panel (dash lower panel 3), the partition wall 25 separating the space between the dash panel (dash lower panel 3) and the suspension housing 14 into the front and rear, and the wiring members (wire harness 3) inserted into the insertion portions 25A, 25B, 25C provided in the partition wall 25. 1, 9, 10. The partition wall 25 has a support member (bracket 40) that supports the wiring member and is fixed to the vehicle body, and the support member (bracket 40) has fixing portions (anchor holes 40h, 40i) that fix the wiring member, and supports a sealing member 50 at a position adjacent to (immediately before) the fixing portions (anchor holes 40h, 40i) in the fore-and-aft direction, and the sealing member 50 cooperates with the insertion portions 25A, 25B, 25C of the partition wall 25 to clamp the wiring member (wire harness 31, pipes 32, 33) (see Figures 1, 9, 10).

[0093] According to such a front structure of the vehicle, the wiring members (wire harness 31, pipes 32, 33) are supported on the support member (bracket 40), so that the position of the wiring members that pass through the insertion portions 25A, 25B, 25C of the partition wall 25 is specified, and the positional relationship between the sealing member 50 and the wiring members can be set to a specified value, thereby ensuring sealing performance. In short, it is possible to achieve both the positioning of the wiring members (wire harness 31, pipes 32, 33) and the sealing performance of the insertion portions 25A, 25B, 25C provided in the partition wall 25.

[0094] In addition, in such a vehicle front structure, the sealing member 50 has a first sealing portion (main sealing portion 51) that contacts the routing member, and second sealing portions (lower sealing portion 52, side sealing portion 53) that contact vehicle body members (see suspension housing 14, apron reinforcement 4) and are configured to have lower rigidity than the first sealing portion (main sealing portion 51) (see Figure 9).

[0095] Such a vehicle front structure makes it possible to position the wiring member with a simple configuration while ensuring sealing between the support member (bracket 40) and the vehicle body member (suspension housing 14, apron reinforcement 4).

[0096] In detail, the first seal portion (main seal portion 51), which has higher rigidity than the second seal portion (lower seal portion 52, side seal portion 53), ensures both sealing performance and positional control of the routing member, and the second seal portion (lower seal portion 52, side seal portion 53), which has lower rigidity than the first seal portion (main seal portion 51), ensures reliable sealing between the vehicle body member and the support member (bracket 40).

[0097] Furthermore, in such a front structure of a vehicle, the sealing member 50 (more specifically, the main sealing portion 51) is formed with recesses (51a, 51b) that match the shape of the routing member, and the opening direction of the recesses (51a, 51b) coincides with the mounting direction of the fixing members (clamps 43, 42) that fix the routing member to the fixing portions (anchor holes 40i, 40h) of the support member (bracket 40) (see Figure 9).

[0098] Such a vehicle front structure provides the following functions and effects. In other words, if the routing member is caught in the sealing member 50 (more specifically, the main seal portion 51) when the routing member is assembled, a gap will be created between the sealing member 50 and the routing member. However, as described above, the opening direction of the recesses (51a, 51b) is aligned with the mounting direction of the clamps 43, 42 as fixing members, thereby preventing the occurrence of such a gap and also preventing the sealing member 50 from breaking.

[0099] Furthermore, in such a vehicle front structure, the wiring member (wire harness 31) is provided with a peripheral seal member 34 at a portion that comes into contact with the seal member 50 (see FIGS. 7 and 9). According to such a vehicle front structure, the sealing performance of the outer peripheral seal member 34 can be further improved.

[0100] In addition, in such a vehicle front structure, the support members (brackets 40) are configured as a pair on the left and right and are symmetrical, and the seal member 50 has a third seal portion (upper seal portion 54) configured to be less rigid than the first seal portion (main seal portion 51) at a position facing the partition wall 25 around the recesses (51a, 51b) of the first seal portion (main seal portion 51) (see Figure 9).

[0101] According to this type of front structure of the vehicle, when the support member (bracket 40) and the seal member 50 are arranged on both the left and right sides of the vehicle, the third seal portion (upper seal portion 54) deforms to seal even in areas where there are no recesses (51a, 51b) in the first seal portion (main seal portion 51).Therefore, even if there are wiring members on both the left and right sides of the vehicle (for example, in the case of a structure in which a brake vacuum pipe is routed on only one side of the vehicle), a seal structure can be constructed using support members (brackets 40) that are symmetrical on the left and right sides.

[0102] Furthermore, in the front structure of such a vehicle, the routing member has a high-rigidity routing member (pipe 33) and a low-rigidity routing member (wire harness 31), the sealing member 50 (more specifically, the main seal portion 51) is fixed to the upper surface of the bottom portion 40e of the support member (bracket 40) extending along the vehicle body, the opposing surface 51A of the sealing member 50 facing the partition wall 25 is inclined upward as it approaches the outer side in the vehicle width direction, and the high-rigidity routing member (pipe 33) is arranged on the inner side in the vehicle width direction of the opposing surface 51A, and the low-rigidity routing member (wire harness 31) is arranged on the outer side in the vehicle width direction of the opposing surface 51A (see Figure 9).

[0103] According to such a vehicle front structure, the wiring members (pipes 33) that require positional regulation are disposed on the inner side in the vehicle width direction where the distance from the bottom surface 40e is small, thereby ensuring the positioning of the wiring members (pipes 33). Also, the wiring members (wire harnesses 31) that have a large tolerance for positional regulation can be disposed on the outer side in the vehicle width direction where the distance from the bottom surface 40e is large, and multiple wiring members (wire harnesses 31, pipes 33) with different rigidities can be properly routed while ensuring sealing.

[0104] In the configuration of this invention and the correspondence with the above-mentioned embodiment, The dash panel of the present invention corresponds to the dash lower panel 3 of the embodiment, Similarly, The wiring members correspond to the wire harness 31 and the pipes 32 and 33. The wiring member having low rigidity corresponds to the wire harness 31, The highly rigid wiring member corresponds to the pipe 33, The support member corresponds to the bracket 40, The fixing portion corresponds to the anchor holes 40h and 40i. The fixing members correspond to clamps 42 and 43. The first seal portion corresponds to the main seal portion 51, The second seal portion corresponds to the lower seal portion 52 and the side seal portion 53, The third seal portion corresponds to the upper seal portion 54, The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0105] For example, in the above embodiment, the wiring components are exemplified as a wire harness 31 such as a front harness, a pipe 32 such as a high-pressure cooler pipe, and a pipe 33 such as a brake vacuum pipe, but instead, other wiring harnesses or pipes of different types, or wiring components such as cables, may also be used.

[0106] Furthermore, the number of wiring members inserted into the insertion portions 25A, 25B, and 25C of the partition wall 25 may be less than three or may be three or more, and in this case, the insertion portions of the partition wall 25 should be provided in accordance with the number of wiring members. [Industrial Applicability]
