DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mirror, and more particularly to a structure for attaching a mirror housing to a unit bracket on which a mirror body is mounted.

[0002]

2. Description of the Related Art Conventionally, as a method of fixing a mirror housing to a unit bracket which is housed in a mirror housing and supports a mirror body such as a mirror plate, a front part and a rear part of a mirror housing are particularly integrated. In the case of the formed one-piece structure, for example, it was common to screw the mirror in two directions, that is, the front direction and the side direction.

By the way, in the above-mentioned assembling process, it is desirable that the number of processes is as small as possible even in view of manufacturing costs and the like. Therefore, the present inventors investigated a method of fixing the unit bracket and the mirror housing, which had conventionally required screwing from two directions, only by screwing from the front direction.

[0004]

However, in the case of fixing only in the front direction, the relationship between the screw fixing position and the shape of the mirror housing is restricted. Because of the bias, it has been found that the mirror housing flaps due to vibration or the like when the door of the vehicle is closed, causing abnormal noise, and that it is difficult to reliably position and fix the mirror housing with respect to the unit bracket.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. In mounting a mirror housing to a unit bracket, the number of steps is reduced to improve work efficiency and reduce manufacturing costs. Attachment of the door mirror housing which can reduce the amount of the mirror housing, prevents fluttering of the mirror housing even when screwing only in the front direction, and can surely position and fix the mirror housing with respect to the unit bracket. It is intended to provide a structure.

[0006]

Means for Solving the Problems] Therefore, in the present invention, before the unit bracket (4) to the mirror housing (1) in
In a door mirror housing mounting structure in which the mirror housing (1) is mounted on the unit bracket (4) by being inserted from the front opening (1d) of the mirror housing (1), the unit bracket (4) is located on the vehicle body side. A projection (9) is provided at the end, and a tongue (11) having a fitting hole (11a) into which the projection (9) can be fitted is provided on the vehicle body side of the mirror housing (1). 9) is fitted into the fitting hole (11a) to perform positioning and temporary fixing of the mirror housing (1) with respect to the unit bracket (4).

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is an exploded perspective view of a main part showing a mounting structure of a door mirror housing according to the present invention, FIG. 2 is a partially broken front view of a door mirror according to the present invention,
FIG. 3 is a partially broken plan view of the door mirror according to the present invention.

[0008]

1 to 3 show a door mirror to which a door mirror housing mounting structure according to the present invention is applied. The door mirror includes a mirror housing 1 that houses a mirror plate 2 and a base body 3 that supports the mirror housing 1 so as to be tiltable in the front-rear direction of the vehicle body.
The mirror housing 1 is composed of a housing cover 5 which covers the opening 1b on the side surface of the vehicle-side end portion and is retained by the mirror housing 1 so as not to come off.

The mirror housing 1 is a substantially rectangular box having a front opening 1d and is integrally formed of a synthetic resin. Inside the mirror housing 1, in addition to the mirror plate 2, the mirror plate 2 is tilted vertically and horizontally. A unit bracket 4 made of aluminum die-casting and supported as possible is installed. When the mirror housing 1 is attached to the unit bracket 4, the unit bracket 4 is inserted into the mirror housing 1 and a plurality of locations 4 a and 4 b are screwed from the front to be fixed to each other. I have.

[0010] A projecting end 1c of the mirror housing 1 on the vehicle body side.
Has an opening 1b on the side surface thereof, and a second opening 1a on the bottom surface of the protruding end 1c.
And 1a communicate with each other.

A column-shaped positioning projection 9 projecting toward the vehicle body and having a hemispherical tip is integrally formed at an end of the unit bracket 4 on the vehicle body side. The mirror housing 1 is integrally formed with a tongue piece 11 having a fitting hole 11a into which the positioning projection 9 can be fitted, hanging down from an upper inner wall of the protruding end 1c on the vehicle body side. .
On both sides of the tongue piece 11, a pair of stopper studs 11b, 11b for abutting the cover are formed so as to bulge from the upper inner wall of the protruding end 1c.

When the unit bracket 4 is inserted from the front opening 1 d of the mirror housing 1, the positioning projection 9 is fitted into the fitting hole 11 a of the tongue 11, so that the mirror housing 1 can be inserted into the unit bracket 4. Positioning and temporary fixing can be performed. As described above, first, after the unit bracket 4 is inserted into the mirror housing 1 and positioned and temporarily fixed, a plurality of locations 4a and 4b are screwed from the front. With this configuration, even if the unit bracket 4 and the mirror housing 1 are screwed only in the front direction, the mirror housing 1 is securely fixed to the unit bracket 4, and the mirror housing 1 can be prevented from fluttering. The positioning of the mirror housing 1 can be reliably performed. Further, the immobility of the member during the screwing operation can be ensured.

The vehicle body side protruding end 1c of the mirror housing 1
The opening 1b on the upper side is formed due to molding problems and needs to be covered with the housing cover 5. The housing cover 5 has substantially the same shape as the side opening 1 b of the mirror housing 1, protrudes from the inner surface thereof along the direction in which the housing cover 5 is inserted into the mirror housing 1, and has a pair of first engagement portions at its upper end. The projecting pieces 6, 6 are formed integrally with a second engaging projecting piece 7 substantially at the center. Locking claws 6a, 6a projecting inward are formed at the tips of the first engaging projections 6, 6, respectively, while locking projections projecting upward at the tip of the second engaging projections 7, respectively. A nail 7a is formed. Further, a curved rib 8 having a pair of protrusions 8a, 8a protruding in the same direction as the engagement protrusions 6, 6, and 7 is formed on the bottom of the housing cover 5.

The housing cover 5 is connected to the mirror housing 1
When mounting on the mirror housing 1, the side opening 1b
And the locking claws 6a, 6a of the first engaging projections 6, 6 of the housing cover 5 are attached to the tongue 11, which is suspended in the protruding end 1c of the mirror housing 1. At the same time, the engaging claw 7a of the second engaging projection 7 is engaged with the engaging step 9a of the unit bracket 4, and the pair of projections 8a The lower end flange 10 is inserted into a pair of guide grooves 10a, 10a formed on both side surfaces thereof, and the inner wall surface at the upper end of the housing cover 5 is pushed into a pair of stopper strips 11b, 11b formed on both sides of the tongue piece 11. Touch and engage.

That is, the first engaging projections 6, 6 of the housing cover 5 are locked to the tongue 11 of the mirror housing 1, so that the housing cover 5 can be prevented from coming off the mirror housing 1 and the left and right positions can be determined. The second engagement projection 7 can be securely mounted on the unit bracket 4.
The curved rib 8 is attached to the unit bracket 4 at the engagement step 9a.
By being locked to the flange portions 10 of the unit bracket 4, it is possible to prevent vertical displacement of the unit bracket 4 with respect to the unit bracket 4 and rotation of the unit bracket 4. With these configurations,
Even when the housing cover 5 made of synthetic resin is temporarily deformed due to an external force acting thereon, the housing cover 5 can be reliably prevented from falling off and held.
Never fall off.
