Description

  The present invention relates to a structure of a vehicle door mirror attached to a side door of a vehicle, a front edge portion of a door opening on a vehicle body side, or the like.

  In a vehicle door mirror, a reflecting mirror for visually recognizing the rear and a holding member for holding the reflecting mirror are accommodated in the mirror housing, and the reflecting mirror is exposed to the outside through an opening facing the vehicle body rear side of the mirror housing. The bracket is coupled to the vehicle body side mirror base through a coupling through hole formed in the lower wall (see Patent Document 1).

In the mirror housing of this door mirror, an enclosing wall is formed continuously on the lower wall where the coupling through-hole is formed, and the side and upper sides of the reflecting mirror are continuously formed. An inner wall flange that is bent in the direction and faces the outer peripheral end surface of the reflecting mirror is integrally extended. The inner wall flange is gently curved toward the bottom side of the mirror housing so that the gap with the reflecting mirror can be kept substantially constant even when the angle of the reflecting mirror is adjusted. In addition, a large space is secured between the surface of the mirror housing on the side close to the vehicle body and the inner wall flange, and a coupling through hole in the lower wall is positioned below the space. ing. Thereby, the coupling | bond part with the mirror base in a mirror housing is arrange | positioned in the position offset to the vehicle body side with respect to the opening of a mirror housing.

  However, in this conventional door mirror structure, a large space is secured between the surface of the surrounding wall of the mirror housing on the side close to the vehicle body and the inner wall flange. The housing becomes large.

And measures to avoid this increase in size, it is conceivable to reduce the space between the side surface and the inner wall flange in proximity to the body of the surrounding wall, reducing the space, the inner wall flange lower wall of the mirror housing When the mirror housing is integrally molded, it is discontinuous with the lower wall at the position directly above the coupling through hole in the lower edge of the inner wall flange. A defective part is made.
That is, in the case of the above door mirror, the inner wall flange of the mirror housing has a shape folded inward from the end of the surrounding wall on the opening side. The depth direction (the direction from the opening toward the bottom) is such that the core die cutting direction for forming the coupling through hole in the lower wall is orthogonal to the base die cutting direction. When the core die cutting direction is perpendicular to the base die cutting direction, the core die enters a part of the shaped part of the inner wall flange located directly above the coupling through hole, and enters the inner wall flange. A defective part will be formed.

  However, if a non-continuous defect portion is formed on the lower edge of the inner wall flange in this way, there is a concern that the inside of the mirror housing can be seen through the defect portion due to the rotating state of the reflecting mirror.

  Therefore, the present invention is intended to provide a vehicle door mirror structure capable of enlarging the reflecting mirror and improving the appearance quality.

The invention according to claim 1, which solves the above problem, includes a reflecting mirror (for example, a reflecting mirror 5 in an embodiment described later) and a holding member for holding the reflecting mirror (for example, a mirror bracket 9 in an embodiment described later). Is accommodated in a mirror housing (for example, a mirror housing 6 in an embodiment described later), and a support shaft (for example, a vertical axis) is extended to a mirror base (for example, a mirror base 2 in an embodiment described later) on the vehicle body side. A support shaft 4 in an embodiment described later is provided, and the holding member penetrates a lower wall of the mirror housing (for example, a lower wall 10 in the embodiment described later) (for example, in an embodiment described later). while being rotatably coupled to said mirror base of the support shaft via the coupling holes 14), the reflecting mirror of the mirror housing opening ( For example, the mirror housing faces the outside through an opening 7 in an embodiment described later, and the mirror housing is connected to the lower wall and the side wall of the reflecting mirror that surrounds the side wall and the upper side of the lower wall (for example, described later) An enclosure wall 11) according to the embodiment, and an inner wall flange that is bent inward from the opening-side end of the enclosure wall and extends in the front-rear direction of a door mirror installed in a normal posture and faces the outer peripheral end surface of the reflecting mirror (For example, an inner wall flange 12 in an embodiment described later), and a discontinuous defect portion (for example, a lower edge of the inner wall flange at a position directly above the coupling through-hole, for example, the lower wall) , a door mirror structure for a vehicle defect 20) is formed in the embodiment described later, the holding member is coupled base portion coupled to the support shaft (for example, the linking group will be described in the exemplary embodiment 16) and an extended part (for example, an extension in an embodiment described later) in which a cross section inclined obliquely in the vertical direction and the vehicle width direction extends in the vehicle longitudinal direction from the coupling base. Part 18), and the extension part constitutes a covering member that covers the defect part.
Thereby, the defect | deletion part of an inner wall flange is covered with the extension part of a holding member, and the inside of a mirror housing does not become exposed through a defect | deletion part.

According to a second aspect of the invention, the vehicle door mirror structure according to claim 1, wherein the extending portion includes a wherein are located the defect portion to be connected with a surface that is continuous with the inner wall flange To do.

According to a third aspect of the present invention, in the vehicle door mirror structure according to the first or second aspect, the holding member extends from the coupling base portion in the vehicle width direction with respect to the door mirror installed in a normal posture. The extending portion and the reflecting mirror holding portion are arranged substantially at right angles .

According to the first aspect of the present invention, since the missing portion of the lower edge of the inner wall flange is covered by the extending portion of the holding member, the missing portion of the lower edge of the inner wall flange is unavoidable as the reflecting mirror is enlarged. However, the inside of the mirror housing can no longer be seen through the defect, and as a result, it is possible to achieve both enlargement of the reflecting mirror and improvement of the appearance quality.
According to the first aspect of the present invention, since the covering member that covers the defect portion is formed by the extending portion that is formed integrally with the holding member that holds the reflecting mirror, the increase in the number of parts is eliminated, and the product cost is reduced. Soaring can be suppressed.

According to the second aspect of the present invention, since the extending portion that covers the defect portion is arranged in the defect portion so as to be connected to the inner wall flange by a continuous surface , the inner wall flange is discontinuous in appearance near the defect portion. In addition, the appearance quality can be further improved.

  An embodiment of the present invention will be described below with reference to the drawings. In the following description, when the door mirror 1 is installed in a normal posture on the vehicle body, the side facing the rear side of the vehicle body is referred to as the front surface, and the upper and lower surfaces refer to the upper and lower in the vehicle body mounted state, respectively. .

  FIG. 1 shows the appearance of a door mirror 1 of a vehicle employing the present invention. In the figure, 2 is a mirror base attached to a front end portion of a side door (not shown), and 3 is a door mirror body attached to a support shaft 4 of the mirror base 2 so as to be rotatable.

In the door mirror main body 3, a reflecting mirror 5 that reflects the rear side of the vehicle body from the driver's seat is accommodated in a resin mirror housing 6, and the reflecting surface of the reflecting mirror 5 faces the outside through an opening 7 on the front surface of the mirror housing 6. Yes.
FIG. 2 shows the door mirror main body 3 with the reflecting mirror 5 removed. As shown in FIG. 2, an actuator unit 8 for adjusting the angle of the reflecting mirror 5 and an actuator are provided inside the mirror housing 6. A mirror bracket 9 (holding member) that holds the reflecting mirror 5 via the unit 8 is accommodated. FIG. 3 shows the door mirror body 3 from which the actuator unit 8 is further removed in addition to the reflecting mirror 5.

  The mirror housing 6 includes a lower wall 10 that covers the lower side of the reflecting mirror 5 and the mirror bracket 9, and a frame-shaped surrounding wall 11 that is connected to the lower wall 10 and surrounds the side and upper side of the reflecting mirror 5. An inner wall flange 12 that is bent inward of the mirror housing 6 and faces the outer peripheral end surface of the reflecting mirror 5 with a minute gap is integrally extended at the edge of the surrounding wall 11 on the opening 7 side. The inner wall flange 12 is slightly curved toward the center of the bottom of the door mirror main body 3 so as to allow the rotational displacement of the reflecting mirror 5 while maintaining a minute gap. Further, the inner wall flange 12 is curved from the upper side region 12a toward the lower ends of the side region 12b and 12c on both sides so as to follow the shape of the outer peripheral end surface of the reflecting mirror 5, and the lower end of the side region 12b on the outer side of the vehicle is lower. It is smoothly continuous with the upper surface of the wall 10. However, the lower end of the side region 12c on the vehicle inner side (the side close to the vehicle body) and the upper surface of the lower wall 10 are not completely continuous, and a substantially rectangular defect portion is formed on the lower edge of the side region 12c. 20 is formed. Further, as shown in the cross-sectional views of FIGS. 2 and 4, the inner wall flange 12 is provided with a plurality of ribs 13 that are curved and extend in the depth direction, and these ribs 13 extend in the depth direction of the mirror housing 6. It is designed to form the bottom of the.

  A housing cover 30 made of a resin material having the same color as the vehicle body is attached to the outer surface of the mirror housing 6 on the bottom side. The housing cover 30 has a front end portion in close contact with a rear end portion from the surrounding wall 11 to the lower wall 10 of the mirror housing 6, and continuously forms the outer surface of the door mirror body 3 together with the mirror housing 6. . A notch 31 is formed at an end of the housing cover 30 on the vehicle exterior side, and a winker lamp 32 for a door mirror is attached to the notch 31.

By the way, at the position of the lower wall 10 of the mirror housing 6 that is biased toward the vehicle body side, as shown in the cross-sectional views of FIGS. A coupling through-hole 14 is formed through which is inserted. The coupling through-hole 14 is formed from the vicinity of the opening 7 in the lower wall 10 of the mirror housing 6 to the portion close to the bottom, and the support shaft of the mirror base 2 inserted through the coupling through-hole 14. 4 is coupled to a mirror bracket 9 in the mirror housing 6. In addition, the missing portion 20 at the lower edge of the side region 12 c on the inner side of the inner wall flange 12 is formed at a position directly above the coupling through hole 14. When the mirror housing 6 is molded, the missing portion 20 of the inner wall flange 12 is inevitably formed by a core mold that forms the coupling through hole 14.
That is, the mirror housing 6 is formed with the inner wall flange 12 in which the edge on the side of the opening 7 of the surrounding wall 11 is bent, so that the drawing direction of the base mold that forms the whole matches the depth direction of the mirror housing 6. The extraction direction of the core mold that forms the coupling through hole 14 is a direction orthogonal to the extraction direction of the base mold. Then, since the die-cutting direction of the core mold interferes with the shaping portion of the inner wall flange 12, the defective portion 20 is inevitably formed at the corresponding portion of the inner wall flange 12.

  FIG. 7 shows the appearance of the mirror bracket 9 coupled to the mirror base 2 through the coupling through-hole 14. As shown in FIG. 7, the mirror bracket 9 includes a unit holding portion 17 for supporting the actuator unit 8 on the vehicle outer side of the coupling base portion 16 (see FIG. 6) with the support shaft 4. In the state where the plate-like extension portion 18 (covering member) is provided on the front side of the coupling base portion 16 and the mirror bracket 9 is installed in the mirror housing 6, the extension portion 18 is the missing portion 20 of the inner wall flange 12. To cover. The extending portion 18 is formed in a substantially arc shape in cross section, and is a curved surface in which the lower edge of the side region 12 c of the inner wall flange 12 and the lower wall 10 of the mirror housing 6 are visually continuous in a state of covering the defect portion 20. It is supposed to be connected.

  As described above, in the door mirror 1, the missing portion 20 at the lower edge of the inner wall flange 12 of the mirror housing 6 is covered so as to be visually continuous by the extending portion 18 of the mirror bracket 9. Even if the lower edge of the inner wall flange 12 is exposed from the opening 7 of the mirror housing 6 by adjusting the angle of the mirror 5, the inside of the mirror housing 6 cannot be seen through the defect 20. Accordingly, the appearance quality of the door mirror 1 can be improved reliably.

  In the case of this door mirror 1, the connecting portion of the mirror base 2 and the mirror bracket 9 is arranged so as to partially overlap the back portion of the reflecting mirror 5 in the mirror housing 6, so that the inner wall flange 12 of the mirror housing 6 Although the defect 20 is inevitably formed on the lower edge, the reflecting mirror 5 can be sufficiently enlarged in the width direction without increasing the size of the mirror housing 6.

  Moreover, in the door mirror 1 of this embodiment, since the extension part 18 was integrally formed in the mirror bracket 6, and the extension part 18 was made into the coating | coated member which covers the defect | deletion part 20, a separate coating | coated member is added. Compared to the case, the number of parts can be reduced, and the product cost can be further reduced. In particular, since the mirror bracket 9 is a large component coupled to the mirror base 2 and the mirror housing 6, there is an advantage that the missing portion 20 can be always covered in a stable posture.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
