Description

  The present invention relates to a vehicle door structure.

  As a vehicle door structure applied to an automobile, Patent Document 1 describes a structure having a door mirror on the front side of a front door. On the inner side in the vehicle width direction of the door mirror, there is a division bar that partitions the door opening. When viewed in the vehicle width direction, the door mirror body and the division bar partially overlap.

  By the way, in the structure of patent document 1, the space | interval (distance) of a door mirror main body and the member (mirror base or division bar) of the door main body side changes suddenly according to the presence or absence of a mirror base. In other words, since the mirror base exists at the inner side in the vehicle width direction at the lower part of the door mirror main body, the distance between the door mirror main body and the mirror base is short, but at the upper part of the door mirror main body, the mirror base exists at the inner side in the vehicle width direction. There is a long gap between the door mirror body and the division bar.

  As described above, when the distance between the door mirror main body and the door main body side member is suddenly changed, the flow velocity of air around the door mirror main body is locally different during traveling of the vehicle, which causes turbulence. When the wiper is driven with moisture adhering to the front window glass during rainy weather, the liquid flowing down along the division bar may be scattered by the turbulent flow described above.

JP 2011-42352 A

  This invention considers the said fact and makes it a subject to obtain the vehicle door structure which can suppress scattering of the liquid which flowed down along the division bar.

According to the first aspect of the present invention, the mirror base is mounted on the vehicle door by a mirror base disposed on the outer surface of the vehicle door, and a support portion projecting outward in the vehicle width direction from the mirror base. a door mirror body at least partially located above, at least partially Ri Do heavy the door mirror body and partially as viewed in the vehicle width direction while positioned above said mirror base, one external shape of the vehicle The division bar is attached to the outer surface of the division bar in the vehicle width direction, and extends upward from the mirror base as seen from the rear side of the vehicle and bulges from the division bar toward the door mirror body. And a bulging member whose upper end is positioned above the upper end of the door mirror of the door mirror body.

  In this vehicle door structure, a mirror base is disposed on the outer surface of the vehicle door, and the door mirror body is attached to the vehicle door by a support portion that protrudes outward from the mirror base in the vehicle width direction. In the mounted state, at least a part of the door mirror main body is located above the mirror base.

  Further, when the vehicle door structure is viewed in the vehicle width direction, at least a part of the division bar is located above the mirror base and partially overlaps the door mirror body as viewed in the vehicle width direction.

  A bulging member is bulged from the division bar. The bulging member is continuous from the mirror base, and its upper end (hereinafter referred to as “bulging member upper end”) is located above the door mirror upper end of the door mirror body. Therefore, compared with the structure without a bulging member, it is suppressed that the space | interval of the edge part inside a vehicle width direction of a door mirror main-body part and the member (mirror base or division bar) on the door main body side changes rapidly. For this reason, generation | occurrence | production of the turbulent flow around a door mirror main body is suppressed at the time of vehicle travel. Since the generation of turbulent flow is suppressed, even if the liquid flows down along the division bar, the liquid is suppressed from scattering due to the turbulent flow described above.

  Note that “the upper end portion is located above the door mirror upper end portion of the door mirror body” in the bulging member is not only a structure in which the upper end portion of the bulging member is completely located above the door mirror upper end portion. Including those having substantially the same height.

  According to a second aspect of the present invention, in the first aspect of the invention, when viewed from the rear of the vehicle, the outer edge of the mirror base in the vehicle width direction and the outer edge of the bulging member in the vehicle width direction are straight lines. Is continuous.

  That is, a structure in which a step is generated at the boundary portion between the mirror base and the bulging member and is discontinuous, or an outer edge in the vehicle width direction of the mirror base and an outer edge in the vehicle width direction of the bulging member Even if the structure is bent when viewed from the rear of the vehicle, the occurrence of the turbulent flow described above can be suppressed as compared with a structure without a bulging member. If the outer edge in the vehicle width direction of the protruding member is continuous in a straight line, the distance between the inner edge in the vehicle width direction of the door mirror main body and the member on the door main body (mirror base or bulging member) is suddenly changed. However, it can suppress more effectively. For this reason, generation | occurrence | production of a turbulent flow can be suppressed more effectively.

  According to a third aspect of the invention, in the invention of the first or second aspect, the bulging member is separate from the mirror base and the division bar.

  In this way, by separating the bulging member from the mirror base or division bar, the edge of the door mirror main body in the vehicle width direction and the door main body side without greatly changing the structure of the mirror base or division bar. The structure which suppressed the sudden change of the space | interval with this member is realizable.

  According to a fourth aspect of the invention, in the invention of the first or second aspect, the bulging member is integrally formed with the mirror base by extending the mirror base upward.

  Thus, the number of parts is reduced by integrating the bulging member with the mirror base. Further, in the work of attaching the mirror base to the door body, the bulging member can also be attached to the door body (division bar), and the workability is improved.

  Since the present invention is configured as described above, a vehicle door structure capable of suppressing scattering of the liquid flowing down along the division bar is obtained.

It is a rear view which shows the front door of the vehicle to which the vehicle door structure of 1st Embodiment of this invention was applied. 1 is a perspective view showing a front door of a vehicle to which a vehicle door structure according to a first embodiment of the present invention is applied. It is a rear view which shows the front door of the vehicle to which the vehicle door structure of the comparative example was applied. It is a perspective view which shows the front door of the vehicle to which the vehicle door structure of the comparative example was applied. It is a perspective view which shows a mode that a liquid flows down along the division bar of a vehicle with a part of vehicle. It is a rear view which shows the front door of the vehicle to which the vehicle door structure of the modification of 1st Embodiment of this invention was applied.

  FIG. 1 partially shows a front door 14 of a vehicle to which a vehicle door structure 12 according to a first embodiment of the present invention is applied as viewed in the vehicle width direction together with a part of a vehicle body (side view). Has been. FIG. 2 shows the vehicle door structure 12 as viewed from the rear of the vehicle. Further, FIG. 3 shows the vehicle door structure 12 in a perspective view. In the drawing, the front side of the vehicle is indicated by an arrow FR, the upper side of the vehicle is indicated by an arrow UP, and the outer side in the vehicle width direction is indicated by an arrow OUT.

  The front door 14 includes a door main body 16 and a door mirror 18 attached to the door main body 16.

  The door body 16 includes a door outer panel 20 that forms a part of the appearance of the vehicle. A frame-shaped door sash frame 22 is provided above the door outer panel 20. A division bar 24 extending in the vertical direction is provided between the door sash frame 20 and the door belt line 16L (a line along the upper edge of the door outer panel 20). The division bar 24 is a member that divides the opening portion surrounded by the door outer panel 20 and the door sash frame 22 in the front-rear direction, and may be referred to as a division pillar. In the present embodiment, the division bar 24 is disposed at a position closer to the front of the vehicle so as to incline toward the rear of the vehicle as it goes upward.

  As can be seen from FIG. 2, the door mirror 18 is disposed at a position outside the division bar 24 in the vehicle width direction. The door mirror 18 includes a mirror base 26U that is fixed to the door body 16 and a door mirror body 28 that is attached to the door body 16 by a support portion 26L that extends outward in the vehicle width direction from the mirror base 26.

  A part (upper part) of the door mirror main body 28 is located above the mirror base 26U. As can be seen from FIG. 1, a part of the division bar 24 (above the middle part) is also located above the mirror base 26U. As can be seen from FIGS. 1 and 3, when viewed in the vehicle width direction, the lower portion of the division bar 24 partially overlaps the door mirror body 28.

  A bulging member 30 is attached to the outer surface of the division bar 24 (the outer surface in the vehicle width direction). In the present embodiment, as shown in FIGS. 1 and 2, locking pieces 32 are provided at the middle and lower portions of the bulging member 30 in the vertical direction. The bulging member 30 can be locked to the division bar 24 by locking these locking pieces 32 to the locked portion 34 provided on the division bar 24 and the mirror base 26. Furthermore, the bulging member 30 is fixed to the division bar 24 with an adhesive, a double-sided adhesive tape, or the like as necessary.

  As can be seen from FIG. 2, the upper portion of the bulging member 30 is an inclined portion 30T that is inclined so as to approach the division bar 24 as the edge 30E on the outer side in the vehicle width direction goes upward. The upper end of 30T is the upper end 30A of the bulging member 30. In the bulging member 30, a portion other than the inclined portion 30 </ b> T (an intermediate portion and a lower portion in the vertical direction) is a parallel portion 30 </ b> S whose edge portion 30 </ b> E is substantially parallel to the division bar 24 when viewed from the vehicle rear side.

  Further, when viewed from the vehicle rear side, the bulging member 30 has a shape and a position extending upward so as to continue from the mirror base 26U. In particular, an edge 30E on the outer side in the vehicle width direction of the bulging member 30 and an edge 26E on the outer side in the vehicle width direction of the mirror base 26U located below the bulging member 30 are substantially linearly continuous at these boundary portions. .

  Further, the upper end 30 </ b> A of the bulging member 30 is positioned above the upper end portion (door mirror upper end portion 18 </ b> A) of the door mirror main body 28. Therefore, by providing the bulging member 30 having such a shape, the door mirror 18 (door mirror body 28) and the door body 16 side members (mirror base 26 and division bar 24) when viewed from the rear side of the vehicle. In the intermediate portion, there is no structure in which the distance D1 changes suddenly.

  Next, the operation of the vehicle door structure 12 of this embodiment will be described.

  As shown in FIG. 2, in this embodiment, the bulging member 30 attached to the division bar 24 causes the door mirror main body 28 and the door main body 16 side members (the mirror base 26 and the division base 26 to be viewed from the vehicle rear side). There is no structure in which the distance D1 changes suddenly with the bar 24).

  Here, FIGS. 4 and 5 show a vehicle door structure 102 of a comparative example. In the comparative example, the bulging member 30 of the above embodiment is not provided, but the other configuration is the same as that of the above embodiment.

  As can be seen from FIG. 4, in the vehicle door structure 102 of the comparative example, the distance D <b> 1 is different between the portion where the mirror base 26 exists and the portion where it does not exist outside the division bar 24 in the vehicle width direction. The interval sudden change portion 104 is generated.

  Here, in the present embodiment and the comparative example, a case where the liquid flows down through the division bar 24 is considered. For example, as shown in FIG. 6, raindrops and washer liquid adhering to the windshield 36 are wiped to the outside in the vehicle width direction (for example, in the vicinity of the front pillar 38) by driving the wiper, and this liquid is further removed from the roof rail portion 40. This occurs when traveling through the division bar 24, such as overcoming the

  In the vehicle door structure 102 of the comparative example, since the interval sudden change portion 104 exists, a part of the air flow AF during vehicle traveling becomes a turbulent flow TR in the vicinity of the lower portion of the division bar 24. The turbulent flow TR may cause a part of the liquid LF flowing down through the division bar 24 to be scattered around.

  On the other hand, in the vehicle door structure 12 of the present embodiment, by providing the bulging member 30, a portion where the distance D1 changes suddenly between the door mirror main body 28 and the door main body 16 side member (in the comparative example). There is no sudden change portion 104), and turbulence does not occur in the vicinity of the lower portion of the division bar 24 while the vehicle is traveling. Therefore, it is possible to suppress the liquid flowing down through the division bar 24 from being scattered around.

  In particular, in the vehicle door structure 12 of the present embodiment, the upper end 30A of the bulging member 30 is positioned above the door mirror upper end portion 18A. For this reason, between the door mirror main body 28 and the member on the door main body 16 side, it is possible to reliably prevent a portion where the distance D1 changes suddenly, and the effect of suppressing the occurrence of the turbulent flow described above is high.

  From this point of view, the upper end 30A of the bulging member 30 only needs to be positioned above the door mirror upper end portion 18A. FIG. 7 shows a modified vehicle door structure 52 in which the upper end 30A of the bulging member 30 is set at a higher position than the structure of the embodiment shown in FIG. Particularly in this example, all of the parallel portions 30S of the bulging member 30 are located above the door mirror upper end portion 18A.

  However, if the upper end 30A of the bulging member 30 is set at a too high position, the bulging member 30 is substantially increased in size. Therefore, as long as the condition that the upper end of the bulging member 30 is located above the door mirror upper end portion 18A is preferably not excessively high.

  In the present invention, even if the upper end 30A of the bulging member 30 is substantially at the same height as the door mirror upper end 18A, there is a gap between the door mirror main body 28 and the member on the door main body 16 side. It can be set as the structure which does not produce the site | part which D1 changes suddenly.

  Further, in the vehicle door structure 12 of the present embodiment, as shown in FIG. 2, the edge 30E of the bulging member 30 and the edge 26E of the mirror base 26 are linear when viewed from the vehicle rear side. It is continuous. This also suppresses a sudden change in the distance D1.

  Note that the shape and position of the edge 30E of the bulging member 30 are not limited to those that are linearly continuous with the edge 26E of the mirror base 26 as described above. For example, the structure may be such that the edge 30E of the bulging member 30 is inclined so as to bend with respect to the edge 26E of the mirror base 26 as viewed from the vehicle rear side. Even in this structure, when compared with a configuration without the bulging member 30 (for example, the configuration of the comparative example shown in FIGS. 4 and 5), a rapid change in the distance D1 is suppressed.

  In addition, even if there is a step between the edge 30E of the bulging member 30 and the edge 26E of the mirror base 26 as viewed from the rear side of the vehicle, the distance D1 is smaller than the configuration without the bulging member 30. Sudden changes are suppressed. In the above embodiment, since the edge portions 30E and 26E are bent as described above and the structure in which the edge portions 30E and 26E are stepped can be reliably suppressed from abrupt changes in the distance D1. Moreover, generation | occurrence | production of turbulent flow TR can also be suppressed more effectively.

  In the above description, the bulging member 30 is a member separated from the mirror base 26 and the division bar 24. In this way, by making the bulging member 30 separate from other members, a sudden change in the distance D1 can be suppressed without significantly changing the structure of the mirror base 26 and the division bar 24.

  On the other hand, the bulging member 30 may be integrated with the mirror base 26. Specifically, the mirror base 26 may be shaped so that its upper end is higher than the door mirror upper end portion 18A of the door mirror main body 28. When the bulging member 30 is integrated with the mirror base 26 in this way, the number of parts is reduced as compared with a case where the bulging member 30 is separated. Further, the process of attaching the bulging member 30 to the mirror base 26 and the division bar 24 is not necessary, and the workability is improved.
