[0052] The hinge-side vertical edge portion 19 extends in the up-down direction on the front side of the side door 2. A hinge (not shown) is attached to the hinge-side vertical edge portion 19.

[0053] The non-hinge longitudinal side portion 20 extends in the up-down direction so as to be aligned with the hinge-side longitudinal side portion 19 on the rear side of the side door 2 .

[0054] The lower side portion 21 extends in the front-rear direction so as to connect the lower end portions of the hinge-side vertical side portion 19 and the non-hinge vertical side portion 20 .

[0055] The panel outer member 10 in this embodiment is manufactured so as to be integrally formed with the hinge-side vertical side portion 19 , the non-hinge vertical side portion 20 , and the lower side portion 21 by hot press molding.

[0056] The panel outer member 10 is provided with a reinforcing member 23 a connecting the upper ends of the hinge-side longitudinal side 19 and the non-hinge longitudinal side 20 , and a reinforcing member 23 b connecting the centers of the hinge-side longitudinal side 19 and the non-hinge longitudinal side 20 .

[0057] Figure 3A yes Figure 1 IIIa-IIIa cross-sectional view. Figure 3B yes Figure 1 Sectional view IIIb-IIIb of FIG. Figure 3C yes Figure 1 It should be noted that in Figure 3A In FIG. 1 , the hinge 24 installed between the A-pillar 3 and the hinge-side longitudinal edge portion 19 is indicated by an imaginary line (two-dot chain line).

[0058] like Figure 3A As shown, the panel outer member 10 is formed from the front edge 16 of the panel outer member 10 formed by the hinge side longitudinal side portion 19 toward the vehicle width direction inner side ( Figure 3A The panel outer member 10 extends from the left side thereof to form an inner edge 29 of the panel outer member 10. The panel outer member 10 forms an overlapping portion 31 with the front edge 11 of the panel inner member 9 at the inner edge 29.

[0059] Specifically, the hinge-side longitudinal side portion 19 has a portion facing inward in the vehicle width direction ( Figure 3A The hinge side longitudinal side portion 19 has a flange portion 25 that is bent and extended in the middle of the bending extension to the rear. Figure 3A The panel outer member 10 forms an overlapping portion 31 with the front edge 11 of the panel inner member 9 by using the extension portion 26.

[0060] Note that the flange portion 25 in the present embodiment extends in the front-rear direction and the up-down direction along the door panel plane (the general surface of the inner panel 7 ).

[0061] At the overlap portion 31, the front edge 11 of the panel inner 9 is joined to the inner edge 29 of the panel outer 10 from the outside in the inward and outward direction of the door hollow portion 34. The door hollow portion 34 is formed between the outer panel 8 and the inner panel 7.

[0062] The overlapping portion 31 of the panel outer member 10 and the panel inner member 9 is joined by spot welding or the like.

[0063] like Figure 3B As shown, the panel outer member 10 extends from the lower edge 18 of the panel outer member 10 formed by the lower side portion 21 toward the inner side in the vehicle width direction ( Figure 3B The panel outer member 10 is bent and extended to form the upper edge 22 of the panel outer member 10. The panel outer member 10 forms an overlapping portion 32 with the lower edge 13 of the panel inner member 9 by using the upper edge 22.

[0064] Specifically, the lower side portion 21 has a Figure 3B The panel outer member 10 has a flange portion 27 (upper edge) extending upward midway along the left side of the panel. The panel outer member 10 forms an overlapping portion 32 with the lower edge 13 of the panel inner member 9 by using the flange portion 27.

[0065] Note that the flange portion 27 in the present embodiment extends in the front-rear direction and the up-down direction along the door panel plane (the general surface of the inner panel 7 ).

[0066] At such an overlapping portion 32 , the lower edge 13 of the panel inner 9 is joined to the upper edge 22 of the panel outer 10 from the outside in the inward and outward direction of the door hollow portion 34 .

[0067] The overlapping portion 32 of the panel outer member 10 and the panel inner member 9 is joined by spot welding or the like.

[0068] In addition, if Figure 3C As shown, the panel outer member 10 has a rear edge 17 of the panel outer member 10 formed from the non-hinge longitudinal side portion 20 toward the vehicle width direction inner side ( Figure 3C The flange portion 28 (inner edge) is bent and extended forward in the middle of the bending extension (left side) of the panel. The hingeless vertical side portion 20 forms an overlapping portion 33 with the rear edge 12 of the panel inner member 9 by using the flange portion 28.

[0069] In addition, the flange portion 28 in the present embodiment extends in the front-rear direction and the up-down direction so as to be along the door panel plane (the general surface of the inner panel 7 ).

[0070] At such an overlapping portion 33 , the rear edge 12 of the panel inner member 9 is joined to the flange portion 28 from the outside in the inward-outward direction of the door hollow portion 34 .

[0071] The overlapping portion 33 of the panel outer member 10 and the panel inner member 9 is joined by spot welding or the like.

[0072] The vehicle door structure 1 of this embodiment (see Figure 1 ) has a hollow tubular sealing member 6 (refer to Figures 3A to 3C ), the sealing member 6 is made of a rubber elastic body, and is used for sealing the side door 2 in the closed state (see Figure 1 ) is sealed between the main body side component surrounding the opening on the side of the vehicle.

[0073] like Figure 3A As shown, the side door 2 (refer to Figure 1 ) The front-side sealing member 6 is located at the overlapping portion 31, which serves as the junction between the panel outer member 10 and the panel inner member 9. This sealing member 6 is fixed to the front edge 11 of the panel inner member 9 and abuts against the A-pillar 3, which serves as the main body member. Thus, the sealing member 6 separates the interior 30a of the vehicle cabin from the exterior 30b.

[0074] like Figure 3B As shown, the side door 2 (refer to Figure 1 ) The lower seal member 6 is positioned adjacent to the overlap portion 32, i.e., the junction between the panel outer member 10 and the panel inner member 9. This seal member 6 is secured to the lower edge 13 of the panel inner member 9 and abuts against the main body outer member 5a of the side sill 5, which serves as the main body member. Thus, the seal member 6 separates the interior 30a of the vehicle cabin from the exterior 30b.

[0075] like Figure 3C As shown, the side door 2 (refer to Figure 1 ) The rear sealing member 6 is positioned adjacent to the overlapping portion 33, i.e., the junction between the panel outer member 10 and the panel inner member 9. This sealing member 6 is fixed to the rear edge 12 of the panel inner member 9 and abuts against the B-pillar 4, which is a main body member. Thus, the sealing member 6 separates the interior 30a of the vehicle cabin from the exterior 30b.

[0076] Effects

[0077] Next, the functions and effects of the vehicle door structure 1 according to the present embodiment will be described.

[0078] The sealing member 6 of the door structure 1 of this embodiment is arranged in the gap between the main body side members such as the A-pillar 3, the B-pillar 4, the main body outer member 5a and the side door 2, separating the interior 30a of the vehicle and the exterior 30b of the vehicle. Figure 3A ) or overlapping portions 32, 33 (see Figure 3B and Figure 3C ), that is, the portion adjacent to the joint between the panel outer member 10 and the panel inner member 9 is mounted on the panel inner member 9 side (refer to Figure 3A 、 Figure 3B and Figure 3C ).

[0079] In such a vehicle door structure 1, water such as rainwater or car wash water may enter the vehicle door hollow portion 34 through the gap between the upper edge of the panel outer member 10 and the upper edge of the panel inner member 9, which serves as the lift opening for the vehicle window glass (not shown). The water that enters the vehicle door hollow portion 34 flows downward along the inner wall surfaces of the panel outer member 10 and the inner wall surfaces of the panel inner member 9.

[0080] Figure 4 yes Figure 3B A partial enlarged view of part IV.

[0081] like Figure 4 As shown, below the door hollow portion 34 , water 40 in the door hollow portion 34 flows out from the overlapping portion 32 of the panel inner member 9 and the panel outer member 10 to the outside of the door hollow portion 34 .

[0082] In the vehicle door structure 1 of the present embodiment, since the sealing member 6 is attached to the panel inner member 9 side, it is possible to prevent the water 40 from intruding into the vehicle interior 30 a.

[0083] In addition, in the vehicle door structure 1, the front edge 11 (see Figure 3A )、lower edge 13 (refer to Figure 3B ) and trailing edge 12 (refer to Figure 3C ) are joined to the inner edge 29 (refer to FIG. Figure 3A )、flange portion 27 (refer to Figure 3B ) and flange portion 28 (refer to Figure 3C ).

[0084] According to such a vehicle door structure 1, unlike a structure in which the edge of the panel outer member 10 is joined from the outside of the vehicle door hollow portion 34, as shown in FIG. Figure 4 As shown, the water 40 in the door hollow portion 34 flows out to the outside of the door hollow portion 34 more reliably.

[0085] In this door structure 1, the flange 28 of the non-hinge longitudinal side 20 and the flange 27 of the lower side 21 respectively form overlapping portions 32 and 33 that overlap the panel inner 9. Furthermore, the extension 26 of the hinge-side longitudinal side 19 forms an overlapping portion 31 that overlaps the panel inner 9.

[0086] According to the vehicle door structure 1 , the joint between the panel inner 9 and the panel outer 10 can be formed by overlapping two components. Therefore, the overlapping portions 31 , 32 , and 33 themselves constitute reinforcements, thereby increasing the rigidity of the inner panel 9 .

[0087] Furthermore, according to the door structure 1, when the side door 2 is closed, the pressing load received from the main body member can be received around the highly rigid overlapping portions 31, 32, 33 via the seal member 6. Thus, the door structure 1 can prevent deformation of the inner panel 7 when closed.

[0088] Furthermore, in the vehicle door structure 1 , the sealing member 6 is fixed to the overlapping portion 31 .

[0089] With this door structure 1, the load input from the main body member via the seal member 6 when the side door 2 is closed can be borne by the overlapping portion 31 itself. This allows the door structure 1 to more reliably prevent deformation of the inner panel 7 caused by the compressive load during closing. Furthermore, the overlapping portion 31 receives the compressive load from the main body member (A-pillar 3) on its surface facing the main body member, significantly reducing deformation.

[0090] Furthermore, in the vehicle door structure 1 , at least the panel outer member 10 of the panel inner member 9 is a thermoformed member.

[0091] The panel outer member 10 of such a door structure 1 has a higher strength than a panel outer member 10 manufactured by a conventional press forming method. It should be noted that the panel inner member 9 in this embodiment assumes a conventional press forming material, but a hot press forming part may also be used.

[0092] Although the embodiments of the present invention have been described above, the present invention is not limited to the aforementioned embodiments and can be implemented in various forms.
