Abstract

PURPOSE:To improve the outer-appearance quality by installing a surrounding plate part integrally onto a reinforcement so that a collapsible mechanism can not be seen from the gap between a mirror housing and a mirror. CONSTITUTION:In a reinforcement 22, the press-attaching basic part 29 is press- attached onto a base bracket 18 by the cooperation of a compression coil spring 32 and a bush nut 33. A surrounding plate part 34 is integrally formed onto the press-attaching basic part 29 of the reinforcement 22. Said surrounding plate part 34 surrounds a shaft 19 as collapsible mechanism, insertion cylinder part 28, and the compression coil spring 32 so that these articles can not be seen from the gap between a mirror 27 and a mirror housing 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a foldable door mirror device.

Traditionally, as shown in Fig. 5, on the door 2 of a car 1,
A device equipped with a foldable door mirror device 3 is known. As shown in FIG. 6, this conventional door mirror device 3 is roughly composed of an L-shaped base member 4 fixed to the door 2 and a door mirror body 5. The base member 4 has an upright portion 6 and a base portion 7, and the upright portion 6 is formed with a boss portion 8 for attachment to the door 2. The door mirror assembly W3 has a door mirror main body 5 that is rotated relative to the base member 4 to be folded down.Next, the detailed structure of the door mirror assembly W3 will be described with reference to FIGS. 7 and 8.

As shown in FIG. 7, the door mirror body 5 includes a mirror housing 9, and the mirror housing 9 covers a mirror 10 and an electric unit 11 for operating the mirror. Mirror housing 9.

It is fixed to a reinforcement 12 for reinforcing the mirror housing, and the reinforcement 12 has a shape as shown in FIG. This reinforcement 12 has a through-tube portion 1 that forms part of the folding mechanism (1!).
It has 3. A shaft 14 is provided at the base 7 of the base member 4 to protrude toward the inside of the mirror housing 9, and this shaft 9 is inserted into the insertion tube portion 13. A compression coil spring 15 is wound around the insertion cylinder portion 13, and this compression coil spring 15 has the ability to press the reinforcement member 1-12 against the base portion 7 by the action of the pusher nut 1-16. ing.

Note that I7 is a harness for the electric unit (see Japanese Utility Model Application No. 55-6162).

As shown in FIG. 9, this foldable door mirror device is constructed by moving the reinforcement 12 around the shaft 14 in the direction of the arrow A-A. The mirror 10 and the opening periphery 9 of the mirror housing 9 can be folded down by rotating.
Since there is a gap 9b between the door mirror body 5 and the door mirror body 5, the insertion tube 13 as a mechanism for folding the door mirror body 5 is inserted through the gap 9b.
, shaft 14, and compression coil spring 15 are visible, which poses a problem in appearance quality.

To achieve I1, the present invention provides an enclosing plate part integrated with the reinforcement to prevent the collapsible mechanism from being seen through the gap between the opening periphery of the mirror housing and the mirror. It is located where the .

According to this structure, the folding mechanism is surrounded by the surrounding plate part so as not to be visible from the gap between the mirror housing and the mirror.

Embodiments of the foldable door mirror device according to the present invention will be described below with reference to the drawings shown in FIGS. 1 to 4.

In FIG. 1, 18 is a base bracket,
This base bracket 18 is fixed to the base 7 of the base member 4. The base bracket 18 has a shaft 1
9 is press-fitted and fixed, and the shaft 19 protrudes toward the inside of a mirror housing 20 that constitutes a part of the door mirror body 5.

This mirror housing 20 is fixed by screws 21 to a reinforcement 22 for reinforcing the mirror housing. In Figure 2, 23 indicates this screw':! 1 shows the mounting boss portion of No. 1. Reinforcement 22
An electric unit 24 for operating the mirror is fixed with a screw 25, and the electric unit 24 operates a mirror 27 via a mirror holder 26.

The mirror housing 20 has the function of covering the electric unit 24 including the mirror, and has the function of covering the electric unit 24 including the mirror.
2 has an insertion tube portion 28 through which the shaft 19 is inserted, as shown in FIGS. 3 and 4.

The lower end portion of this insertion tube portion 28 serves as a crimp base portion 29 that is crimp-bonded to the base bracket 18 . The shaft 19 is configured to pass through the insertion tube 28, and a locking claw 30 of a bush nut, which will be described later, is formed on the protruding peripheral edge of the shaft 19. The shaft 19 has a through hole, and the harness 31 is connected to the electric unit 24 through this through hole.

A compression coil spring 32 is wound around the insertion tube 28, and a bush nut 33 is attached to the shaft 19 to apply compression force to the compression coil spring 32. The reinforcement 22 has its crimp base 29 pressed against the base bracket 18 by the cooperation of the compression coil spring 32 and the bush nut 33.

The reinforcement 22 has a crimp base 29,
As shown in FIGS. 3 and 4, the surrounding plate portion 34 is integrally formed. This enclosing plate part 34 includes the shirt 1-19 as a folding mechanism, the insertion tube part 28, and the compression coil spring 3 through the gap 9b between the mirror 27 and the mirror housing 20.
2 surrounds the folding mechanism so that it cannot be seen. This surrounding plate part 34 has a front plate part 35 that prevents the folding mechanism from being seen from the front direction when the mirror 27 is activated.
and a side plate portion 36 that prevents the folding mechanism from being seen from inside the vehicle.

Here, the reinforcement 22 is manufactured by a die-cast manufacturing method, and the wall thickness of the surrounding plate 34 is adjusted so that the operating range of the mirror 27 does not become smaller than in the past due to the provision of the surrounding plate 34. It is preferable to manufacture the reinforcement 22 as thin as possible. Furthermore, in order to prevent the reinforcement 22 from being visible from the outside, it is preferable to paint it black.

In addition, in FIGS. 3 and 4, 37 indicates a reinforcing plate portion of the reinforcement 22, 538 indicates an insertion hole for the screw 21, and 39 indicates a connection portion with the crimp base 29. .

2. As explained above, the present invention prevents the folding mechanism from being seen through the gap between the mirror housing and the mirror by means of the surrounding plate integrally formed with the reinforcement. This has the effect that it is possible to improve the appearance quality of the type door mirror device.

Furthermore, since the surrounding plate portion is formed integrally with the reinforcement, the rigidity of the reinforcement itself can be increased.

Furthermore, in the past, the shafts and springs that make up the collapsible mechanism were coated with black paint in order to make it as difficult as possible for the collapsible mechanism to be inserted through gaps; however, according to the present invention, such a coating is applied. Since the folding mechanism can be prevented from being seen even if the folding mechanism is not opened, the cost can be reduced accordingly.
