Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror device for a vehicle, such as a rear view side mirror, provided outside the vehicle, and more particularly to a structure of a mirror holding member of the mirror device for a vehicle.

[0002]

2. Description of the Related Art In general, a side mirror mounted on a vehicle such as an automobile holds a mirror plate (reflecting mirror) in a mirror body at a mirror mounting portion, and the mirror mounting portion is a pivot serving as a rotation support shaft. It is rotatable in the vertical and horizontal directions around the center. The mirror mounting portion in the mirror body can be adjusted to the optimum angle manually or by adjusting the inclination angle of the mirror body using an electric motor.

FIG. 7 is a front view showing a schematic structure of an example of a conventional mirror mounting portion, and FIG. 8 is B'-B 'in FIG.
9 is a cross-sectional view taken along the line C′-C ′ in FIG. Note that, in each figure, the symbol A is the rear side of the vehicle body, R is the right side of the vehicle body,
U indicates the upper side of the vehicle body.

As shown in FIG. 7, a conventional mirror mounting portion 6 'has a flat main body portion 61' formed along the back surface of a substantially square mirror plate 7. The peripheral edge of the main body 61 'has a substantially uniform thickness over the entire circumference. However, as shown in FIG. 8, the vicinity of the tip of the linear portion 62a' is once bent into a U-shape once. The mirror plate 7 is raised in the thickness direction of the mirror plate 7 and has a hook shape. This hook-shaped portion forms a fitting portion 62 'for fitting the mirror plate 7, and
When the mirror plate 7 is fitted, the bent portion 63 in the shape of
2 ′ is made elastically deformable.

The U-shaped bent portion 63 bends easily with respect to the bending force in the bending direction.
When it is provided at a ′, its bending action can be sufficiently exhibited. However, since the U-shaped bent portion 63 has a very large sectional modulus with respect to a bending force in a direction perpendicular to the bending direction,
If this is applied to the corner portion 62b ', the bending force in the bending direction and the bending force in the right-angle direction are simultaneously applied. As a result, the elastic deformation of the fitting portion 62' is prevented, and the bending action cannot be exerted.

Although the U-shaped bent portion 63 protrudes greatly on the back surface side, a number of electrical components (not shown) are mounted in the mirror body on the back surface side, and the U-shaped bent portion 63 is located near the corner 62b '. If the mirror-shaped bent portion 63 is provided, when the mirror mounting portion 6 'is inclined, the overhang interferes with the electrical component and hinders the inclination, which is a problem.

Conventionally, therefore, a U-shaped bent portion 63 is not provided for a corner portion 62b ', which may interfere with electrical components, and the tip thereof is raised immediately at a right angle as shown in FIG. Was in a state. In this case, when assembling the mirror plate 7 to the mirror mounting portion 6 ', the vicinity of the corner portion 62b' is not particularly elastically deformed.
Cannot be fitted as it is.

Therefore, in order to facilitate the fitting of the mirror plate 7, as a material of the mirror holding member 6, a synthetic resin having a property of softening when heated, for example, polypropylene (PP) is employed. When assembling the mirror plate 7 to the mirror plate 7, the mirror plate 7 is fitted by appropriately heating and then bending the entire periphery of the main body portion 61 'of the mirror mounting portion 6'.

[0009]

However, in the above prior art, it is necessary to assemble the mirror mounting portion 6 'on a sub-assembly line different from the main assembly line in order to heat the mirror mounting portion 6'. Therefore, it is necessary to move the mirror mounting portion 6 'between the lines, which causes a reduction in the efficiency of the side mirror assembling operation.

The mirror mounting portion 6 'made of polypropylene is greatly affected by the temperature during assembly, and naturally becomes soft in summer when the temperature is high, so that the mirror plate 7 can be easily assembled, but the temperature is low. In the winter season, the mirror plate 7 becomes naturally hard, and it becomes difficult to assemble the mirror plate 7. Therefore, it is necessary to change the heating condition depending on the season, which also causes the efficiency of the side mirror assembling operation to be reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has as its object to provide a vehicle mirror device capable of improving the efficiency of assembly work by omitting a heating step. I have.

Since the inclined surface for elastically deforming is formed, the material of the mirror holding member is elastically deformed so that the hook portion of the fitting portion opens outward just by inserting the mirror plate without heating and softening the material. Thereby, the mirror plate is easily fitted to the mirror holding member.

Accordingly, it is not necessary to use a heat-softening material for the mirror holding member, and as a result, the range of material selection is expanded. Also, unlike the conventional example, it is not necessary to move the mirror holding member between lines for the heating process, and it is not necessary to change the heating condition depending on the season (air temperature).
The efficiency of the assembly work of the mirror device is greatly improved.

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 portion 6 is supported by an adjust gear or the like (not shown) provided on the actuator portion 5. By driving the adjust gear or the like, the installation angle of the mirror mounting portion 6 and the mirror plate 7 is changed in the left-right direction (s direction). And fine adjustment in the vertical direction (u direction).

FIG. 2 is a plan view showing the entire configuration of the mirror device according to the first embodiment of the present invention, and FIG.
FIG. 4 is a cross-sectional view taken along line CC of FIG. 2, and FIG. 5 is an enlarged view of a portion D in FIG.

As shown in FIGS. 2 to 5, the mirror mounting portion 6 is a molded product made of, for example, polypropylene (PP), and is formed in a substantially rectangular flat plate shape when viewed from the front. The vicinity of the portion 62b has a thin-walled structure (65) that can be bent in a non-heated state and fitted with the mirror plate 7.

In the vicinity of the center of the mirror mounting portion 6, a curved-surface-shaped engaging portion 101 fitted into the tilt support portion of the housing of the actuator portion 5 and a pair of spherical heads of the adjusting gear are fitted. Is formed. The joint portion 102 has a spherical concave portion corresponding to the diameter of the spherical head.

Further, the engaging portion 101 of the mirror mounting portion 6
An elastically urged mounting member (not shown) having a hemispherical pressing surface is screwed into the inside of the mirror mounting portion 6.
A pivot center that restricts the movement of the robot.

By attaching the mirror mounting portion 6 to the housing, the adjustment gear head projecting rearward from the housing and the joint portion 102 formed on the mirror mounting portion 6 are engaged. Become.

Here, the mirror plate 7 is curved so as to form a convex surface, and the periphery of the mirror mounting portion 6 conforms to the shape of the mirror plate 7. The mirror plate 7 has a fitting portion 62 formed on the entire periphery of the mirror mounting portion 6.
And is appropriately integrated with the mirror mounting portion 6 by being appropriately supported by the ribs 104 from the mirror mounting portion 6.

A plurality of ribs 104 are formed concentrically and radially with the pivot center as the center. Here, all of the ribs 104 are tapered downward in accordance with the curved shape of the mirror plate 7.
A protruding portion 105 that can be elastically protruded and retracted is provided near the tip of the radial rib, and the protruding portion 105 and a hook-shaped portion of a fitting portion 62 described later form a corner portion 62 b of the mirror plate 7. Can be positioned at a predetermined position.

Here, the fitting portion 62 on the periphery of the mirror mounting portion 6
Among them, the linear portion 62a has a substantially uniform thickness, as in the above-described conventional example, and its vicinity is bent once into a U-shape and then raised in the thickness direction of the mirror plate 7. It is hooked (see FIG. 3). An inclined surface 64 is formed inside the hook-shaped portion so that the end of the mirror plate 7 to be fitted is brought into contact with the hook-shaped portion and the hook-shaped portion is elastically deformed so as to be opened outward by this contact force.

However, the corner portion 62b which may interfere with the electrical components in the mirror body 2 is not provided with the above-mentioned U-shaped bent portion 63, and as shown in FIG. The same inclined surface 6 as above
It has a hook shape with four. Then, the thickness of the portion immediately before the rising is greatly reduced to form the thin portion 65, so that the mirror plate 7 can be elastically deformed when fitted. The thickness reduction amount is set so that elastic deformation is possible, but each end face of the reduced thickness portion is appropriately rounded so as not to be damaged by the notch effect.

A U-shaped bent portion 63 can be provided for the corner portion 62b which does not interfere with the electrical components in the mirror body 2, but the U-shaped bent portion 63 is bent in the bending direction. Since the section modulus with respect to the bending force in the right-angle direction is very large, if it is applied to the corner portion 62b, the bending force in the bending direction and the bending force in the right-angle direction are simultaneously applied, thereby preventing the elastic deformation of the fitting portion 62. The bending effect cannot be exhibited. Therefore, in this case, it is necessary to provide the thin portion 65 immediately inside the U-shaped bent portion 63. In FIG. 2, such a thin portion 65 is also provided.

In the first embodiment, as described above, at least the corner portions 62 on the periphery of the main body portion 61 of the mirror mounting portion 6 are provided.

The mirror plate 7 is deformed so that the portion 65 is bent and the hook portion of the fitting portion 62 is opened outward, so that the mirror plate 7 is
To be easily fitted. Further, the fitting portion 6 of the mirror mounting portion 6
Since the inclined surface 64 was formed inside the hook-shaped part of 2,
Just by inserting the mirror plate 7, the hook portion of the fitting portion 26 is elastically deformed so as to open outward, and the mirror plate 7 is further easily attached to the mirror mounting portion 6 together with the operation effect of the thin portion 65. Is fitted to.

Therefore, it is not necessary to use a heat-softening material for the mirror mounting portion 6, so that the range of material selection can be expanded. Therefore, it is possible to reduce the cost of the product by using a material that is easy to mold or an inexpensive material. Further, unlike the conventional example, it is not necessary to move the mirror mounting portion 6 between the lines for the heating process, and it is not necessary to change the heating condition depending on the season (air temperature). Efficiency can be greatly improved.

(Embodiment 2) Incidentally, since the fitting portion 62 is formed continuously, the elastic deformation thereof can be increased by breaking this connection. The second embodiment has been made focusing on this point, and will be described below.

FIG. 6 is an enlarged view of a portion E in FIG. 2. In the mirror mounting portion 6 according to the second embodiment, at least the corner portion 62b has a peripheral portion of the main body portion 61 and a fitting portion 62 connected to the hook portion. Is provided in the circumferential direction with a slit portion 67 notched by a predetermined width. The predetermined width is set within a range in which the hook portion of the fitting portion 62 can be elastically deformed, but it is necessary to keep the fitting force as small as possible in order to maintain the fitting force. In the second embodiment, the predetermined width is empirically adjusted to the protrusion amount of the hook-shaped portion of the fitting portion 62.

In this case, even if the material of the mirror mounting portion 6 is not heated and softened, the slit portion 67 is deformed so as to open in the circumferential direction and open the hook portion of the fitting portion 62 outward. The mirror plate 7 is easily fitted to the mirror mounting portion 6. Also, since the inclined surface 64 is formed inside the hook-shaped portion of the fitting portion 62 of the mirror mounting portion 6, the mirror plate 7
The mirror plate 7 is elastically deformed so that the hook-shaped portion of the fitting portion 26 is opened outward just by inserting the mirror portion 7, and the mirror plate 7 is more easily fitted to the mirror mounting portion 6 in combination with the operation effect of the slit portion 67. Is done.

Therefore, according to the second embodiment, the same effect as that of the first embodiment can be obtained by using a molded product similar to that of the conventional example for the mirror mounting portion 6 itself, and then cutting the slit thereafter. Can be. Therefore, in the second embodiment, the factory equipment can be easily adopted as it is, which is convenient.

In the first embodiment, the inclined surface 64 formed in the hook-shaped portion of the fitting portion 62 is provided together with the thin portion 65. In the second embodiment, the inclined surface 64 is provided together with the slit portion 67. However, only the inclined surface 64 may be provided. Even in such a case, the material of the mirror mounting portion 6 is elastically deformed so that the hook-shaped portion of the fitting portion 26 is opened outward only by fitting the mirror plate 7 without heating and softening the material. Is easily fitted to the mirror mounting portion 6.

In the first embodiment, the mirror mounting portion 6 has a substantially square shape according to the shape of the mirror plate 7.
The corner portion 62b has a thin structure (65).
The thin portion 65 may be provided over the entire periphery of the mirror mounting portion 6, and in that case, the entire periphery can be formed in the same shape, so that the structure is simplified and the molding process is facilitated.

Further, in the first and second embodiments, the mirror mounting portion 6 has a substantially square shape in accordance with the shape of the mirror plate 7, but both may have a polygonal shape having a plurality of other corner portions. , Or even circular. Although the mirror plate 7 has a curved shape, a flat plate shape may be used. In that case,
Since the heights of the ribs 104 are the same, the configuration is simpler. Further, the material of the mirror mounting portion 6 does not need to be limited to a material which is easily deformed by heating, as in the conventional example.

In the first and second embodiments, the horizontally long side mirror of a small passenger car has been described. However, the scope of the present invention is not limited to this, and for example, a fender mirror may be used. May be a vertically long side mirror of a large vehicle. Further, the mirror device may not be of an electric type but may be of a type capable of manually adjusting the angle.

[0047]

According to the first, third and fifth aspects of the present invention,
As a result, there is no need to use a heat-softening material for the mirror holding member, so that the range of material selection can be expanded. Therefore, it is possible to reduce the cost of the product by using a material that is easy to mold or an inexpensive material. Further, it is not necessary to move the mirror holding member between lines for heating processing as in the conventional example, and it is not necessary to change the heating conditions depending on the season (air temperature). Efficiency can be greatly improved. According to the third aspect of the present invention, the mirror holding member itself uses a molded product similar to that of the conventional example, and the above-mentioned effect can be obtained only by cutting a slit later. This is convenient.
