[0035] Next, a mode (embodiment) for carrying out the vehicle front side structure of the present invention will be described in detail with reference to appropriate drawings.

[0036] The main feature of the vehicle front structure of the present embodiment is that a plate member having protrusions that come into contact with the side panel outer member of the front pillar and the fender panel is provided as a sealing member.

[0037] The vehicle front side structure of the present embodiment is respectively arranged on both sides of the vehicle corresponding to the left and right front pillars. Since these components have a mutually symmetrical structure, only the vehicle front side structure on the left side of the vehicle is described below, and the detailed description of the vehicle front side structure on the right side of the vehicle is omitted.

[0038] It should be noted that the front, rear, up, down, left, and right directions in the following description are based on the arrow directions in the drawings that coincide with the front, rear, up, down, left, and right directions of the vehicle.

[0039] Figure 1 It is a configuration explanatory diagram of the vehicle front structure 1 according to the present embodiment, and is a partially enlarged side view of the left front pillar as viewed from the vehicle outer side. Figure 1 Most of the sealing member 3 is shown by hidden lines (dashed lines).

[0040] like Figure 1 As shown, the vehicle front structure 1 is mainly composed of a side panel outer member 4 forming a front pillar 2 , a fender panel 5 , and a sealing member 3 .

[0041] like Figure 1 As shown, the front pillar 2 in the present embodiment extends between the windshield 21 and the sub-window glass 22 and is inclined so as to be displaced rearward as it goes upward.

[0042] Although not shown in the drawings, the upper portion of the front pillar 2 is connected to the front end portion of a roof side rail extending in the front-rear direction at the outer side in the vehicle width direction of the roof of the vehicle.

[0043] Furthermore, at the lower portion of the front pillar 2 , a fender panel 5 extending upward from a portion of the side surface of the front portion of the vehicle body and having the same width as the front pillar 2 overlaps the side panel outer 4 from the vehicle outer side.

[0044] Figure 2 The figure shows the vehicle width as viewed from the inside. Figure 1 The illustrated embodiment is a partially enlarged perspective view of a state near a joint between the side panel outer 4 of the front pillar 2 and the fender panel 5 .

[0045] like Figure 2 As shown, the lower end portion of the side panel outer member 4 extending from the upper side toward the lower side and the upper end portion of the fender panel 5 extending from the lower side toward the upper side are opposed to each other with a predetermined gap therebetween.

[0046] In addition, the side panel outer member 4 is aligned with the fender 5 in the extending direction of the front pillar 2 and forms a step difference, thereby forming the inner side of the fender 5 ( Figure 2 The two sides of the paper are overlapped in a manner similar to the inner side of the paper.

[0047] Figure 3 yes Figure 2 III-III sectional view.

[0048] exist Figure 3 In the cross-sectional view shown, the fender 5 in the front pillar 2 extends from the rear side to the front side in the front-rear direction of the vehicle to the outside of the vehicle ( Figure 3 In addition, the front edge and the rear edge of the fender 5 are bent toward the side panel outer member 4 in a manner of forming an R (corner).

[0049] Figure 4 yes Figure 2 IV-IV cross-sectional view.

[0050] like Figure 4 As shown, the upper end of the fender 5 faces the inner side in the vehicle width direction ( Figure 4 That is, the upper end portion of the fender 5 forms a bent portion 11 that is bent toward the side panel outer member 4 that is the inner side of the fender 5.

[0051] like Figure 3 As shown, the side panel outer member 4 includes: an outer side surface 6, which is opposite to the inner side surface 12 of the fender 5 with a predetermined gap therebetween; and an inner side surface 7, which is folded back and extended rearward from the front end edge of the outer side surface 6. Incidentally, the inner side surface 7 gradually extends inward in the vehicle width direction ( Figure 4 Although not shown in the figure, the windshield 21 is mounted on the inner side 7 by means of a molded part (see Figure 1 ).

[0052] In addition, if Figure 4 As shown, the side panel outer member 4 is formed with a portion extending from the joint with the fender 5 toward the inner side in the vehicle width direction (see Figure 4 The side panel outer member 4 is bent and extended in the middle of the inner side extension in the vehicle width direction, forming the outer side surface 6 (see FIG. Figure 3 ).

[0053] In addition, the side panel outer member 4 has a convex portion 9 partially bulging toward the fender 5 side at a portion overlapping with the fender 5 in the vehicle inner and outer directions. The convex portion 9 has a portion on the side opposite to the step surface 8 that gradually moves inward in the vehicle width direction as it approaches the step surface 8 ( Figure 4 The inclined surface 9a is displaced (on the right side of the arrow).

[0054] Next, the sealing member 3 (see Figure 1 ).

[0055] like Figure 2As shown in FIG. 1 , the sealing member 3 is disposed between the side panel outer member 4 and the fender 5 at a portion where the side panel outer member 4 and the fender 5 overlap in the vehicle inner and outer directions. Figure 2 In FIG. 1 , a portion of the seal member 3 disposed between the side panel outer 4 and the fender panel 5 is indicated by a hidden line (dashed line).

[0056] like Figure 2 As shown, when the front pillar 2 is viewed from the plane, the sealing member 3 includes, from the outside of the vehicle to the inside of the vehicle: a base 13, which is substantially rectangular; and a hook portion 14, which extends from the inside of the base 13 in the vehicle width direction ( Figure 2 The end edge (on the right side of the arrow) is bent toward the rear side in the front-rear direction of the vehicle and extends along the inner side surface 7 of the side panel outer member 4.

[0057] In addition, the sealing member 3 includes: a flange portion 15 formed along the upper edge of the base 13; a protrusion 17 formed along the lower edge of the base 13 and in contact with the fender 5; and a protrusion 16 (see Figure 5A ), which contacts the side panel outer member 4 described later.

[0058] It should be noted that the protrusion 16 that contacts the side panel outer member 4 corresponds to the "first protrusion" in the claims. Also, the protrusion 17 that contacts the fender 5 corresponds to the "second protrusion" in the claims.

[0059] Figure 2 The sealing member 3 in the present embodiment shown is assumed to be formed by integrally molding the above-mentioned base portion 13, hook portion 14, flange portion 15, protrusion portion 17 and protrusion portion 16 (see Figure 5A ) is a resin molded product made of olefin-based thermoplastic elastomer (TPO: Thermoplastic Olefinic Elastomer) or the like. However, the material of the sealing member 3 is not limited thereto.

[0060] Figure 5A It is an overall perspective view of the sealing member 3 . Figure 5B is from Figure 5A The side view of the sealing component 3 observed from the Vb direction. It should be noted that, Figure 5A and Figure 5B The state in which it is arranged in front of the front pillar 2 is shown. Figure 5A , a cross section of the base member 13 is shown and the protrusion 16 (first protrusion) is indicated by a hidden line (dashed line).

[0061] like Figure 5A As shown in FIG. 1 , the base 13, which is substantially rectangular in plan view, is curved in its length direction. Figure 3As shown, when the base portion 13 is disposed between the fender panel 5 and the side panel outer 4 , it is bent substantially along the inner side surface 12 of the fender panel 5 and the outer side surface 6 of the side panel outer 4 .

[0062] like Figure 3 As shown, the rear end edge of the base portion 13 forms a tapered portion 18 whose thickness gradually decreases toward the rear.

[0063] In addition, if Figure 4 As shown, when the base portion 13 is disposed between the fender panel 5 and the side panel outer 4 , the base portion 13 is disposed between the inclined surface 9 a of the convex portion 9 in the side panel outer 4 and the stepped surface 8 .

[0064] Furthermore, the base portion 13 is in contact with the inclined surface 9 a of the convex portion 9 .

[0065] like Figure 5B As shown, the hook portion 14 is formed in a hook shape bent at one end side in the longitudinal direction of the base portion 13 .

[0066] like Figure 2 As shown, when the base portion 13 is disposed between the fender panel 5 and the side panel outer 4 , the hook portion 14 is in surface contact with the inner side surface 7 of the side panel outer 4 in the vehicle width direction.

[0067] The flange portion 15 is as follows Figure 5A As shown, the base 13 is formed to extend along one long side of the substantially rectangular base 13 .

[0068] The flange portion 15 protrudes in a direction opposite to the direction in which the hook portion 14 bends and extends.

[0069] Specifically, if Figure 2 As shown, the flange portion 15 projects toward the fender 5 that is the vehicle outer side when viewed from the base portion 13 side.

[0070] It should be noted that in Figure 2 and Figure 5A In the figure, reference numeral 19 denotes a groove-shaped recessed portion formed in the base portion 13 so as to extend along the flange portion 15 .

[0071] like Figure 4 As shown, when the base portion 13 is disposed between the fender panel 5 and the side panel outer 4 , the front end of the bent portion 11 in the fender panel 5 faces such a recessed portion 19 .

[0072] Furthermore, the flange portion 15 contacts the bent portion 11 from above.

[0073] like Figure 5A As shown, the protrusion 16 (first protrusion) is formed in a rib shape extending along the longitudinal direction of the base 13 on the surface of the base 13 opposite to the surface on which the recess 19 is formed.

[0074] And, if Figure 4 As shown in FIG. 1 , when the base 13 is disposed between the fender 5 and the side panel outer member 4, the protrusion 16 is drawn by the imaginary line (two-dot chain line). Figure 5A The position of the initial state shown is rotated along the base 13 so as to be tilted downwardly toward the arrow in the axial direction Ax of the front pillar 2 .

[0075] As a result, the protrusion 16 generates an elastic restoring force and comes into contact with the outer side surface 6 of the side panel outer 4 .

[0076] like Figure 5A As shown, the protrusion 17 (second protrusion) that contacts the fender 5 is formed to extend along the other long side of the substantially rectangular base 13 , which is located on the opposite side to the one long side forming the flange 15 .

[0077] like Figure 4 As shown in FIG. 1 , when the base 13 is disposed between the fender 5 and the side panel outer member 4, the protrusion 17 is drawn by the imaginary line (two-dot chain line). Figure 5A The position of the initial state shown is rotated toward the side panel outer 4 side and tilted downward in the axial direction Ax of the front pillar 2 .

[0078] As a result, the protrusion 17 generates an elastic restoring force and comes into contact with the inner surface 12 of the fender panel 5 .

[0079] Such a sealing member 3 is provided from the inner side in the vehicle width direction ( Figure 2 Insert in the direction of the blank arrow Figure 2 The front pillar 2 is mounted to the vehicle front pillar 2 by filling a gap between the fender 5 and the side panel outer member 4 of the vehicle front pillar 2 as shown.

[0080] At this time, the sealing member 3 is Figure 3 The tapered portion 18 side shown is inserted between the fender 5 and the side panel outer member 4 .

[0081] When the protrusion 16 (first protrusion) is inserted into the gap between the fender 5 and the side panel outer member 4, it can slide by sliding contact with the side panel outer member 4. In addition, when the protrusion 17 (second protrusion) is inserted into the gap between the fender 5 and the side panel outer member 4, it can slide by sliding contact with the fender 5.

[0082] And, if Figure 3 As shown, the seal member 3 inserted into the gap between the fender 5 and the side panel outer 4 has its hook portion 14 bonded to the inner side surface 7 of the side panel outer 4 using a double-sided tape 23. Thus, the seal member 3 is attached to the front pillar 2, and the vehicle front structure 1 of this embodiment is completed.

[0083] 《Effects》

[0084] Next, the functions and effects of the vehicle front structure 1 according to the present embodiment will be described.

[0085] In the vehicle front structure 1, the seal member 3 contacts the side panel outer 4 and the fender 5 via the protrusions 16 and 17. Therefore, when the seal member 3 is inserted between the side panel outer 4 and the fender 5, the seal member 3 can slide relative to the side panel outer 4 and the fender 5.

[0086] According to such a vehicle front structure 1 , after applying the rust-proof paint between the side panel outer 4 and the fender panel 5 , the sealing member 3 can be easily slid and assembled between the side panel outer 4 and the fender panel 5 .

[0087] According to the vehicle front structure 1 of the present embodiment, the seal member 3 is provided between the side panel outer 4 of the front pillar 2 and the fender panel 5 , and rust between these panels can be prevented.

[0088] Furthermore, according to the vehicle front structure 1 , the protrusions 16 and 17 generate elastic restoring force and come into contact with the side panel outer 4 and the fender panel 5 , so that the seal member 3 can be prevented from being displaced relative to the side panel outer 4 and the fender panel 5 .

[0089] Therefore, the sealing member 3 can always provide good sealing performance with the side panel outer member 4 and the fender 5. According to such a vehicle front side structure 1, it is possible to effectively prevent wind noise from being generated in the joint between the side panel outer member 4 and the fender 5. In addition, it is possible to effectively prevent rainwater, cleaning fluid, etc. from penetrating between the side panel outer member 4 and the fender 5.

[0090] Furthermore, in the vehicle front structure 1 , the seal member 3 is in contact with the convex portion 9 of the side panel outer 4 .

[0091] According to such a vehicle front structure 1 , the convex portion 9 can more reliably prevent the seal member 3 from being displaced downward in the axial direction Ax of the front pillar 2 .

[0092] In addition, in such a vehicle front structure 1 , the seal member 3 is in contact with the convex portion 9 on the side of the side panel outer 4 , and the protrusion 17 is in contact with the fender panel 5 .

[0093] According to such a vehicle front structure 1 , the sealing performance of the seal member 3 between the side panel outer 4 and the fender panel 5 is further improved by the elastic force of the protrusion 17 with respect to the fender panel 5 .

[0094] Furthermore, in the vehicle front structure 1 , the seal member 3 has the recessed portion 19 , and the front end of the bent portion 11 of the fender panel 5 faces the recessed portion 19 .

[0095] According to such a vehicle front structure 1 , the bent portion 11 and the recessed portion 19 can suppress the flow of air from the joint between the side panel outer 4 and the fender panel 5 to between the side panel outer 4 and the fender panel 5 .

[0096] Thus, the vehicle front structure 1 can effectively prevent wind noise from being generated at the joint between the side panel outer 4 and the fender panel 5 .

[0097] Furthermore, according to the vehicle front structure 1 , when the seal member 3 is inserted between the side panel outer 4 and the fender 5 , the recessed portion 19 of the seal member 3 serves as a guide groove for the bent portion 11 of the fender 5 , thereby preventing the fender 5 from interfering with the seal member 3 .

[0098] Furthermore, in the vehicle front structure 1 , the flange portion 15 of the seal member 3 contacts the bent portion 11 of the fender panel 5 from above.

[0099] According to the vehicle front structure 1 , the flange portion 15 of the seal member 3 contacts the bent portion 11 of the fender panel 5 , thereby more reliably preventing air from flowing from the joint between the side panel outer 4 and the fender panel 5 to between the side panel outer 4 and the fender panel 5 .

[0100] Thus, the vehicle front structure 1 can more effectively prevent wind noise from being generated at the joint between the side panel outer 4 and the fender panel 5 .

[0101] In the vehicle front structure 1 , the flange 15 of the seal member 3 contacts the bent portion 11 of the fender 5 from above, thereby preventing the bent portion 11 from damaging the flange 15 when the seal member 3 is inserted between the side panel outer 4 and the fender 5 .

[0102] Furthermore, in the vehicle front structure 1 , the hook portion 14 of the seal member 3 is in surface contact with the inner side surface 7 of the side panel outer 4 in the vehicle width direction.

[0103] According to such a vehicle front structure 1 , when the seal member 3 is inserted between the side panel outer 4 and the fender panel 5 , the hook portion 14 serves as a stopper, and the seal member 3 is mounted with high accuracy.

[0104] Furthermore, according to the vehicle front structure 1 , by bonding the hook portion 14 to the inner surface 7 of the side panel outer 4 using the double-sided tape 23 or the like, the seal member 3 is more firmly fixed to the front pillar 2 .

[0105] Furthermore, in the vehicle front structure 1 , a tapered portion 18 is provided on the rear side of the sealing member 3 .

[0106] According to such a vehicle front structure 1 , by inserting the seal member 3 between the side panel outer 4 and the fender panel 5 from the narrow portion 18 side, the seal member 3 can be easily attached to the front pillar 2 .

[0107] In the vehicle front structure 1 , the protrusions 16 and 17 are provided so as to tilt downward in the axial direction Ax of the front pillar 2 .

[0108] According to such a vehicle front structure 1 , the elastic restoring force of the protrusions 16 and 17 is more effectively exerted, so that the fixing force of the seal member 3 in the front pillar 2 becomes more significant.

[0109] Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment and can be implemented in various forms.
