As disclosed in Patent Document 1, in order for the driver to confirm the area below the rear window glass, the rearward confirmation mirror is generally arranged in a downwardly inclined posture toward the rear of the vehicle. Is. Therefore, the rear view mirror is in a state of protruding toward the rear window glass side, that is, downward, and also toward the front of the vehicle.

In Patent Document 1, the tailgate rotates toward the rear of the vehicle while drawing a rotation locus. The rear view mirror attached to such a flip-up tailgate rotates following the rear confirmation mirror when the tailgate is opened and closed. For this reason, the rear view mirror is likely to be loaded when the tailgate is opened and closed, and improvement in support stability is required.

In view of such a problem, the present invention provides a vehicle rear under mirror mounting structure capable of improving the support stability of the rear under mirror for rear confirmation to the back door for a flip-up vehicle. It is an object.

In order to solve the above problems, a typical configuration of the rear under mirror mounting structure for a vehicle according to the present invention is a back door for a flip-up vehicle having a rear window and a back door mounted on the passenger compartment side of the back door. In the rear under mirror mounting structure for vehicles equipped with a rear under mirror that makes the rear of the vehicle below the rear window visible from the driver's seat through the rear window, the back door has an outer panel facing the outside of the vehicle and an inner facing the passenger compartment. Including the panel, the rear window includes a transparent portion that is a central transparent region and a masking portion provided on the periphery of the transparent portion, and the inner panel is continuous around the edge of the back door opening of the vehicle body. The rear under mirror has a mirror body including a mirror surface, and the mirror body is arranged above the transparent part of the rear window in front view, and is in contact with the inner panel. It is characterized in that it is attached to the inner region of the portion.

According to the present invention, it is possible to provide a vehicle rear under mirror mounting structure capable of increasing the support stability of the rear under mirror for rear confirmation to the back door for a flip-up vehicle.

It is a figure explaining the rear under mirror mounting structure for a vehicle which concerns on this Example. FIG. 1 is a sectional view taken along the line AA of FIG. It is an enlarged view of FIG.

The vehicle rear under mirror mounting structure according to an embodiment of the present invention includes a flip-up vehicle back door having a rear window and a back door mounted on the passenger compartment side of the back door and below the rear window through the rear window. In a vehicle rear under mirror mounting structure including a rear under mirror that makes the rear of the vehicle visible from the driver's seat, the back door includes an outer panel facing the outside of the vehicle and an inner panel facing the passenger compartment, and the rear window is The inner panel has an abutting portion that continuously contacts the edge of the back door opening of the vehicle body around the edge of the back door opening of the vehicle body, including a transparent portion that is a central transparent region and a masking portion provided on the peripheral edge of the transparent portion. The rear under mirror has a mirror body including a mirror surface, and the mirror body is arranged above the transparent part of the rear window in front view, and is attached to the inner area of the inner panel inside the contact part. It is characterized by that.

According to the above configuration, the rear under mirror is attached to the inner panel in the area inside the contact portion and above the transparent portion of the rear window. That is, the rear under mirror is attached in the vicinity of the contact portion. Since the abutting portion is continuous around the edge of the opening of the back door of the vehicle body, it has high rigidity. By attaching the rear under mirror in the vicinity of the highly rigid contact portion, it is possible to improve the support stability of the rear under mirror in the inner panel and the back door.

Further, since the rear under mirror is arranged above the transparent portion of the rear window, the rear under mirror does not overhang the transparent portion of the rear window. Therefore, the above-mentioned effect can be obtained without narrowing the transparent portion of the rear window, that is, the field of view of the occupant behind the vehicle.

The rear under mirror may have a mirror support that is attached to the area of the inner panel to support the mirror body, and the inner panel may have an area to which the rear under mirror is attached that bulges toward the rear under mirror. By providing the mirror support as in such a configuration, it is possible to further improve the support stability of the rear under mirror.

Further, as a means for further improving the support stability of the rear under mirror, it is conceivable to increase the size of the mirror support, but according to the present invention, the region of the inner panel to which the mirror support is attached is in contact with the mirror support. It is a region with high rigidity, which is near the part. Therefore, as compared with the case where the mirror support is not provided in such a region, the mirror support of the present invention can be made smaller and lighter, and the protrusion to the rear window can be reduced. Therefore, the rear under mirror does not narrow the driver's field of view to see the rear of the vehicle through the rear window.

Further, according to the present invention, the area where the mirror support is attached in the inner panel is bulged toward the rear under mirror, so that the mirror support is further reduced in size and weight as compared with the case where the mirror support is not bulged. be able to.

Further, if the area where the mirror support is attached is not bulged in the inner panel, the distance from the attachment position between the mirror support and the inner panel to the mirror main body becomes long, so that the support stability becomes low. On the other hand, in the inner panel, the area where the mirror support is attached is bulged, so that the distance from the attachment point to the inner panel to the mirror body is shortened, so that the support of the mirror body and the rear under mirror is stable. It becomes possible to enhance the sex.

In a cross-sectional view of the rear under mirror cut in the front-rear direction of the vehicle, the mirror surface has a concave curvature inside the vehicle, and in the cross-sectional view, the mirror support may not project on the curvature line of the mirror surface. As a result, it is possible to preferably prevent the mirror support from being reflected on the rear under mirror, so that the above-mentioned effect can be obtained without hindering the visibility of the rear under mirror.

It is preferable that the inner panel has a bead shape in which the portion of the region where the mirror support is fixed bulges toward the inside of the vehicle, and the bead shape extends in the vehicle width direction. Thereby, in the area where the mirror support is attached, the rigidity of the portion where the mirror support is fixed can be particularly increased. Further, since the bead shape extends in the vehicle width direction, it is possible to further improve the support stability.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the examples are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are designated by the same reference numerals to omit duplicate description, and elements not directly related to the present invention are not shown. To do.

FIG. 1 is a diagram illustrating a vehicle rear under mirror mounting structure (hereinafter, referred to as mounting structure 100) according to this embodiment. FIG. 1 illustrates a state in which the back door 110 for a vehicle is observed from the inside of the vehicle. FIG. 2 is a cross-sectional view taken along the line AA of FIG.

As shown in FIG. 1, the mounting structure 100 of this embodiment includes a back door 110 and a rear under mirror 160. In this embodiment, the back door 110 is a flip-up type (hatchback type) door that opens and closes while drawing a rotational trajectory toward the rear of the vehicle. The back door 110 is provided with a rear window 112 at the upper portion.

In this embodiment, the rear window 112 has a transparent portion 112a and a masking portion 112b. When the back door 110 is observed from the inside of the vehicle, the masking portion 112b cannot be visually recognized. Therefore, in FIG. 1, the masking portion 112b is shown by hatching for convenience of explanation.

As shown in FIG. 1, in the rear window 112, the transparent portion 112a, which is a transmission region, is located at the center, and a masking portion 112b is provided on the peripheral edge of the transparent portion 112a. As a result, the masking portion 112b covers the adhesive (not shown) applied to the outer edge of the rear window 112 when the rear window 112 is adhesively fixed to the outer panel 120 described later. Therefore, the appearance quality of the rear window 112 can be improved.

The back door 110 includes an outer panel 120 facing the outside of the vehicle and an inner panel 130 facing the passenger compartment. The inner panel 130 of this embodiment has hinge fixing portions 132a and 132b, abutting portions 134, and an opening for a rear window (hereinafter, referred to as an opening 136).

The hinge fixing portions 132a and 132b are provided at the upper ends of the inner panel 130, and hinges (not shown) serving as mounting members to the vehicle body are fixed. As a result, the back door 110 can rotate in the vertical direction while drawing a rotation trajectory around the hinge. The abutting portion 134 is continuous around the outer periphery of the inner panel 130, and abuts on the edge of the back door opening (both not shown) of the vehicle body via the weather strip when the back door 110 is closed. .. An opening 136 is arranged inside the contact portion 134.

The rear under mirror 160 is attached to the passenger compartment side of the back door 110 so that the rear of the vehicle below the rear window 112 can be visually recognized from the driver's seat through the rear window 112. The rear under mirror 160 has a width in the vehicle width direction as shown in FIG. 1, and is arranged so as to incline downward toward the rear of the vehicle in the vehicle front-rear direction. As a result, the reflection area of the rear under mirror 160 can be expanded.

As a feature of the mounting structure 100 of this embodiment, as shown in FIG. 1, the mirror body 140 of the rear under mirror 160 is arranged above the transparent portion 112a of the rear window 112 in front view, and the inner panel 130. Of these, it is attached to the inner region of the abutting portion 134 (hereinafter, simply referred to as a region 138), that is, in the vicinity of the abutting portion 134.

In the inner panel 130, the contact portion 134 that is continuous around the outer circumference has high rigidity because it bears the skeleton of the inner panel 130. Therefore, by attaching the mirror body 140 to the inner region 138 of the highly rigid contact portion 134, that is, the region 138 surrounded by the contact portion 134, the inner panel 130 and thus the rear under mirror 160 are supported by the back door 110. Stability can be increased.

Further, according to the above configuration, the load applied to the rear under mirror 160 when the back door 110 is opened and closed can be transmitted to the entire inner panel 130 via the contact portion 134. Therefore, it is possible to suitably suppress the load concentration in the region 138 where the rear under mirror 160 is attached.

Further, as shown in FIG. 1, the rear under mirror 160 is arranged between the two hinge fixing portions 132a and 132b by attaching the mirror main body 140 to the region 138 above the transparent portion 112a of the rear window 112. .. As a result, since the mirror main body 140 and the hinge fixing portions 132a and 132b are close to each other, it is possible to further improve the support stability of the rear under mirror 160.

Further, by attaching the mirror main body 140 to the region 138 above the transparent portion 112a of the rear window 112, it is possible to prevent the mirror main body 140 from projecting to the transparent portion 112a. As a result, it is possible to obtain the above-mentioned effect while ensuring a good field of view of the occupant behind the vehicle.

As shown in FIGS. 1 and 2, the rear under mirror 160 of this embodiment further has a mirror support 150 that is attached to the area 138 of the inner panel 130 to support the mirror body 140. That is, in this embodiment, the mirror body 140 is attached to the inner panel 130 via the mirror support 150.

Here, as a means for further improving the support stability of the rear under mirror 160, it is conceivable to increase the size of the mirror support 150. However, if the mirror support 150 is enlarged, the amount of protrusion to the rear window 112 becomes large, which causes a decrease in the visibility of the driver.

On the other hand, according to the mounting structure 100 of the present embodiment, the mirror support 150 is mounted in the inner panel 130 in the vicinity of the contact portion 134, which is a highly rigid region 138. Therefore, higher support stability can be obtained without increasing the size of the mirror support 150 as compared with the case where the mirror support 150 is not attached to the region 138. Therefore, in this embodiment, the mirror support 150 can be made smaller and lighter, and the protrusion to the rear window 112 is reduced. As a result, the mirror support 150 and thus the rear under mirror 160 can ensure high visibility without narrowing the field of view of the driver who confirms the rear of the vehicle through the rear window 112.

As described above, in the configuration including the mirror support 150, the area 138 to which the mirror support 150 (rear under mirror 160) of the inner panel 130 is attached bulges toward the rear under mirror 160 as shown in FIG. It is good. If the area 138 to which the mirror support 150 of the inner panel 130 is attached is not bulged, the inner panel 130 has the cross-sectional shape shown by the broken line in FIG. Then, the mirror support 150 must be extended to the position of the broken line, and the weight of the mirror support 150 increases.

When the mirror support 150 is extended to the broken line position, the mirror support 150 is attached to the inner panel 130 at the broken line position. For this reason, the distance (distance) between the attachment point of the inner panel 150 corresponding to the starting point and the action point and the mirror main body 140 becomes long, so that the support stability of the mirror main body 140 deteriorates.

Therefore, in this embodiment, the region 138 to which the mirror support 150 of the inner panel 130 is attached is bulged toward the rear under mirror 160 by the bulging amount D1 and D2. As a result, the mirror support 150 can be attached to the inner panel 130 without extending the mirror support 150. At this time, the distance between the mounting location with the inner panel 130 and the mirror main body 150 is shorter than when the mirror support 150 is mounted on the inner panel at the broken line position. Therefore, it is possible to obtain high support stability while reducing the size and weight of the mirror support 150.

Further, since the bulging shape of the region 138 of the inner panel 130 is covered by the mirror support 150, it is difficult for the occupant to visually recognize it. Further, by providing the bulging shape in the region 138 having high rigidity in the inner panel as in the present embodiment, the above-mentioned effect can be obtained without the bulging shape becoming the starting point of folding.

More preferably, in a cross-sectional view of the rear under mirror 160 cut in the front-rear direction of the vehicle, the mirror support 150 may not project on the curvature line L of the mirror surface of the mirror body 140. Specifically, as shown in FIG. 2, the mirror surface of the mirror body 140 has a concave curvature along the curvature line L inside the vehicle in a cross-sectional view cut in the front-rear direction of the vehicle in order to enhance visibility of the occupant.

Then, in this embodiment, the mirror support 150 is arranged so as not to project on the concave curvature line L of the mirror surface of the mirror body 140. This makes it possible to preferably prevent the mirror body 140 from being reflected on the mirror surface of the mirror support 150. Therefore, it is possible to ensure high visibility in the rear under mirror 160.

Further, in this embodiment, as shown in FIG. 2, the mirror support 150 has a box shape in which the surface in contact with the inner panel 130 is open. By forming the mirror support 150 into a box shape in this way, high rigidity can be obtained, and deformation can be suitably suppressed.

Here, the center of gravity of the mirror support 150 is located at the front portion as shown in FIG. 2 due to the curvature of the mirror surface of the mirror body 140 and the like. Therefore, when the back door 110 is opened, a load that hangs downward is applied to the front portion of the mirror support 150. On the other hand, as in the present embodiment, the mirror support 150 is arranged so as not to project on the concave curvature line L of the mirror surface of the mirror body 140, so that the rear portion of the mirror support 150 is an inner panel. It is in a state of being in contact with 130. Therefore, it is possible to preferably prevent the front portion of the mirror support 150 from hanging down.

FIG. 3 is an enlarged view of FIG. FIG. 3 (a) is an enlarged view of the vicinity of the rear under mirror 160 of FIG. 1, and FIG. 3 (b) shows a state in which the rear under mirror 160 of FIG. 3 (a) is removed. Of the inner panel 130, the area 138 to which the mirror support 150 shown in FIG. 3A and the mirror body 140 are attached via the mirror support 150 has a bead shape that bulges toward the inside of the vehicle shown in FIG. 3B. 170a and 170b are formed.

Specifically, as shown in FIG. 3B, in this embodiment, the fixing points P1, P2, P3, and P4, which are the places where the mirror support 150 is fixed, are provided in pairs at the top and bottom. Moreover, two rows are arranged in the vehicle width direction. The bead shapes 170a and 170b extend in the vehicle width direction so as to connect the two rows of fixed portions P1 to P4.

According to the above configuration, the fixing portions P1 to P4 of the mirror support 150 are arranged in the bead shapes 170a and 170b. High rigidity can be obtained with the bead shapes 170a and 170b that bulge toward the inside of the vehicle. Therefore, by providing the fixing points P1 to P4 on the bead shapes 170a and 170b, it is possible to increase the support rigidity of the mirror support 150 and thus the rear under mirror 160. Further, since the bead shapes 170a and 170b have a width in the vehicle width direction, high rigidity can be obtained also in the vehicle width direction, and the mirror support 150 and thus the rear under mirror 160 can be supported in a more stable state. It becomes.

In the above-described embodiment, the configuration in which the mirror support 150 is directly attached to the inner panel 130 has been illustrated, but the present invention is not limited to this. For example, when a trim (not shown) or the like, which is an interior material, is attached to the inside of the inner panel 130, the mirror body 140 or the mirror support 150 is attached to the inner panel 130 via the trim or the like. It is possible to obtain the same effect.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the claims, which naturally belong to the technical scope of the present invention. Understood.

The present invention can be used for a vehicle rear under mirror mounting structure.
