Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base structure of a vehicle side mirror for rear view, which is provided outside a vehicle.

[0002]

2. Description of the Related Art In general, a side mirror mounted on a vehicle such as an automobile rotates a mirror plate (reflecting mirror) in a mirror body in a vertical direction and a horizontal direction, respectively, around a pivot center serving as a rotation support shaft. The mirror base is movably supported, and includes a mirror base that supports the mirror body so as to be swingably displaceable between a use position and a storage position.

[0003] As such a mirror base, there is a so-called two-piece mirror base comprising an inner base attached to a vehicle body panel so as to protrude outside the vehicle, and a cover base covering the inner base. Further, since the cover base and the inner base are usually made of a synthetic resin, screws, welding, and the like can be adopted as a method for joining them. However, among these screws, as the number of parts increases, the tightening work is troublesome, and the welding requires large-scale equipment, so recently clip connection has been partially adopted. became.

FIG. 5 is a sectional view showing an example in which a clip connection is adopted in a two-piece type mirror base.
In this two-piece type mirror base 1 ′, the clip portion 14 provided on the cover base 12 is connected to the inner base 11.
By engaging the engaging holes 16 provided in the
The clips 1 and 12 are clip-coupled and screwed into place on the vehicle body panel 10 so that the vehicle body panel 10 and the molding 20 are connected to each other with a cushion member 13 ′ having a predetermined shape so that wind noise and water leakage to the opening 10 b do not occur. The contact part was sealed.

For example, the cushion material 13 'has a thickness of 10 mm.
It is formed by cutting out a closed cell of a degree, and is appropriately adhered to the inner surface of the inner base 11 adjacent to this portion from the inner surface of the overhung portion of the cover base 12 with a double-sided tape (indicated by an x in the figure). It was attached and fixed.

[0006]

However, according to the above-mentioned prior art, it is difficult to accurately arrange the cushioning material 13 'at a predetermined position because the double-sided tape x sticks to an unnecessary portion and does not peel off. The poor workability has led to an increase in the cost of the side mirror.

On the other hand, the mirror base 1 'is manufactured separately from the vehicle body assembly factory, and may be transported with the cover base 12 clip-coupled to the inner base 11 before being attached to the vehicle panel. In technology,
During the transfer before the cushion material 13 ′ is brought into contact with the vehicle body panel 10 or the molding 20, there is a possibility that the cushion material 13 ′ may come off due to rattling between the bases 11 and 12.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the work of arranging a cushion material in a multi-piece type mirror base is easy.
It is an object of the present invention to provide a base structure of a vehicle side mirror in which a cushion material does not come off during transfer.

[0009]

According to the first aspect of the present invention,
In a base structure of a vehicle side mirror including an inner base attached to a vehicle body panel and a cover base covering the inner base so as to protrude outside the vehicle, a cushion material is sandwiched between the inner base and the cover base. It is characterized by that.

According to the above configuration, the cushion material is merely narrowed between the inner base and the cover base. Therefore, the cushion material is removed from the inner surface of the overhung portion of the cover base with a double-sided tape. There is no need to fix the inner base to the inner surface adjacent to the portion, and the cushioning material can be accurately arranged at a predetermined position.

By the way, the inner base may be connected to the cover base by a clip. In this case, it is necessary to increase the overstroke (fitting stroke) of the connecting portion in order to easily connect the clip. . However, if the overstroke is increased, rattling occurs between the two bases after the connection, so that reliable clip connection cannot be expected.

Therefore, according to the first aspect of the present invention, if the cover base can be connected to the inner base by a clip (claim 2), the cushion material is narrowed between the inner base and the cover base. As a result, the backlash between the two bases is reduced due to the function of the cushioning material even when the overstroke is set to a relatively large value, and a reliable clip connection between the two bases becomes possible.

Therefore, even when the assembly of the mirror base as a single unit is completed at the mirror assembling factory, and the single unit is transferred to the assembly factory of the vehicle body, there is no possibility that the cushion material will come off during the transfer.

According to the second aspect of the present invention, if the rib material for positioning the inner base is provided inside the cover base (claim 3), the inner base can be easily formed inside the cover base. Since the cushion member is positioned so that an appropriate gap is secured between the bases, the cushion material is less likely to be locally crushed and impair the function, and the play between the bases is further reduced.

In the invention according to the third aspect, if the rib material is set to a height corresponding to the thickness of the cushion material compressed by coupling the two bases (claim 4), Since the amount of compression required for the material is ensured, the function of the cushion material is sufficiently exhibited, and the play between the two bases is further reduced.

It is configured to be displaced. The frame 4 is integrally formed with the gear box 3 so as to protrude therefrom, and an actuator section 5 is attached to a rear surface of the frame 4. The mirror mounting section 6 is supported by a driving mechanism (not shown) provided on the actuator section 5, and by driving the driving mechanism, the installation angles of the mirror mounting section 6 and the mirror plate 7 can be changed in the left-right direction (s direction) and in the horizontal direction (s direction). Fine adjustment is performed in the vertical direction (u direction).

FIG. 2 is a perspective view seen from the direction A in FIG.
FIG. 4 is a cross-sectional view taken along the line BB, and FIG. 4 is a perspective view showing the appearance of the coupler. For convenience of explanation, the same elements as those in FIG. 5 are denoted by the same reference numerals.

As shown in FIGS. 2 and 3, the mirror base 1 is provided with a body panel 10 so as to protrude outside the vehicle.
, A triangular inner base 1 in front view
1 and a cover base 12 covering the inner base 11
And both bases 1 in a state where cushion material 13 is narrowed between inner base 11 and cover base 12.
It is configured so that the clips 1 and 12 are positioned and then clip-coupled.

The cover base 12 is a molded product made of, for example, a synthetic resin, and has a three-dimensional decorative surface on the outside. A portion (clip) 14 and a rib portion (rib material) 15 for positioning are provided. Rib material 1
Numeral 5 is provided in the thickness direction of the cushion material 13, and its height is set so that a slight gap is formed between the bases 11 and 12 after the cover base 12 is clip-coupled to the inner base 11. The clip portion 14 has a large overstroke to facilitate clip connection.

The inner base 11 is a molded product made of, for example, a synthetic resin, and the outside thereof is the cover base 1.
2 has an engagement hole 16 that can engage (join) the clip portion 14. At three inner corner portions (FIG. 2), mounting bosses 17 for supporting the inner base 11 from the vehicle body panel 10 are formed, and the mounting bosses 17 are hollow and are internally threaded, for example. However, the mounting boss 17 may be left hollow, and tapping may be performed with the bolt 10c when inserting the bolt. The rib portion 15
Although it is provided at one position above the mounting boss 17 in FIG. 3, it may be provided at an arbitrary position, or may be provided at a plurality of positions.

At an appropriate position inside the inner base 11, a coupler fixing portion 19 (FIG. 2) for fixing the coupler 18 in an electric wire connection state is provided as shown in FIG. The coupler 18 is a commercially available product and has a fitting groove 18a at the upper part of its housing. The coupler fixing portion 19 has a rib portion 19a made of, for example, a synthetic resin for fitting into the fitting groove 18a. Provided. Conventionally, the fixing of the coupler 18 requires a special part, and the increase in the number of parts and the increase in the number of assembling steps have been problematic. However, according to this configuration, the cost is reduced by suppressing the number of parts. In addition, since the coupler 18 can be easily fixed to the coupler fixing portion 19 inside the inter base 11 by one-touch operation, the number of assembling steps can be reduced.

The cushion material 13 has a thickness of, for example, 1
A sponge of about 2 mm is used, and the cushion material 13 is arranged so as to be disposed around the inner base 11 and the cover base 12.
And the periphery of the clip portion 14 and the rib portion 15 are largely hollowed out. In addition, since the cushion material 13 is used exclusively for preventing wind noise, it is sufficient to use an inexpensive open-cell sponge.

The vehicle body panel 10 has a sheet metal assembly structure composed of a plurality of thin plates, and has a bolt hole 10a formed at a position corresponding to the mounting boss 17 of the inner base 11.
An opening 10b for penetrating an electric wire (not shown) from the actuator section 5 is formed. This opening 1

Are in contact with each other, and the electric wire is made of the urethane-based material 13a.
Is inserted and guided. A molding 20 made of synthetic resin is attached to one end of the vehicle body panel 10.

Hereinafter, a method of manufacturing the side mirror will be described.

First, at a mirror assembly factory, an inner base 11 and a cover base 12 are prepared, a cushion material 13 is set in a suitable place inside the cover base 12, and the inner base 11 is set thereon. Then, the cushion material 13 is sandwiched between the bases 11 and 12. In this state, cover base 1
When the inner base 11 is pressed until the second rib portion 15 once comes into contact with the inner base 11, the tip of the clip portion 14 is
3 is easily fitted into the engagement portion 15 against the elastic force of the third.

Then, when the pressing is released, the inner base 11 is urged in the direction away from the cover base 12 by the elastic force of the cushion material 13, and the clip portion 14 is released.
Are coupled to the engaging portion 15. At this time, a gap of about 6 mm is formed between the two bases 11 and 12, and the cushion material 13 is compressed to approximately half the thickness in the gap and the gap between the two bases 11 and 12 is formed. It keeps the connection state.

At this time, the fitting groove 18a of the coupler 18 is fitted into the rib portion 19a of the coupler fixing portion 19, the coupler 18 is mounted on the coupler fixing portion 19, and the electric wire connected to the coupler 18 is bent. Guide it to an appropriate place.

In this way, when the assembly of the mirror base 1 alone is completed in the mirror assembly factory, the backlash between the two bases 11 and 12 is almost eliminated by the function of the cushioning material 13. In this combined state, the outer edge of the cushion material 13 is free, but most of the cushion material 13 is incorporated into and integrated with the mirror base 1 alone. Even when the cushion material 13 is transferred from the vehicle body to the assembly factory side of the vehicle body, there is no possibility that the cushion material 13 will come off during the transfer, and the transfer is extremely easy.

Then, the mirror base 1 alone is transferred from the mirror assembling plant to the vehicle body assembling plant, and is disposed at a predetermined position of the vehicle body panel 10 in which the molding 20 is incorporated. Comes into contact with the vehicle body panel 10 and the molding 20 and is compressed. In this state, the bolt 10 is inserted into the bolt hole 10a of the vehicle body panel 10.
The mirror base 1 can be mounted on the vehicle by inserting the mirror base c and screwing it into the mounting boss 17.

As described above, according to the present embodiment, only the cushion material 13 is narrowed between the inner base 11 and the cover base 12, so that the cushion material 13 is fixed with a double-sided tape as in the prior art. There is no need to fix, and the cushion material 13 can be accurately arranged at a predetermined position.
Therefore, assembling work of the mirror base 1 is reduced, so that the cost of the side mirror can be reduced.
Further, since the cushion material 13 is also a general-purpose punched material, the cost can be reduced.

Further, in this embodiment, although the clip connection between the inner base 11 and the cover base 12 is facilitated by increasing the overstroke of the clip connection portion, a cushion material is provided between the bases 11 and 12. By virtue of the function of 13, the play is almost eliminated, and a reliable clip connection between the bases 11 and 12 becomes possible. Therefore, after the assembly of the mirror base 1 alone is completed, there is no possibility that the cushion material 13 will come off during the transfer from the mirror assembly factory to the vehicle assembly factory of the mirror base 1 alone, and the transfer becomes extremely easy.

In the above embodiment, the two-piece type mirror base 1 is employed. However, the present invention can be similarly applied to a three-piece or more multi-piece type mirror base. Further, depending on the equipment of the assembly factory of the mirror base 1, instead of the clip connection between the inner base 11 and the cover base 12, the connection may be made by screwing or welding.

In the above embodiment, the side mirror of a small passenger car has been described. However, the scope of the present invention is not limited to this, and may be a side mirror of a large vehicle such as a bus or a truck. Further, the side mirror may not be of an electric type but may be of a type capable of manually adjusting the angle.

[0036]

According to the first aspect of the present invention, the cushion material can be accurately arranged at a predetermined position between the inner base and the cover base which constitute the mirror base, so that the mirror base is assembled. Can be reduced. As a result, the cost of the side mirror can be reduced.

According to the second aspect of the present invention, even when the overstroke in clip connection between the two bases is large, the backlash between the two bases is reduced by the action of the cushion material, and the gap between the two bases is reduced. Clip connection can be ensured. Therefore, by employing such a clip connection, the assembly work of the mirror base can be further reduced, and the cost of the side mirror can be further reduced. Further, after the assembly of the single mirror base is completed, there is no possibility that the cushion material will come off during the transfer of the single mirror base from the mirror assembly factory to the vehicle assembly factory, and the transfer becomes extremely easy.

According to the third and fourth aspects of the present invention, even when the overstroke in the clip connection between the two bases is large, the backlash between the two bases is reduced by the action of the cushion material, and Clip connection between the bases can be further ensured.
