Description

[Detailed Description of the Invention] The present invention relates to an automobile mirror. In particular, the present invention relates to an automobile mirror that prevents distortion of the mirror caused by deformation of the mirror body due to sudden temperature differences that often occur in tropical regions, such as cold regions, and provides good visibility.

Conventionally, in this type of automobile mirror, as shown in FIGS. 1 to 3, a mirror body 2 that holds a mirror 1 that projects a rear view has a pivot portion 4 that is expanded at approximately the center of the back surface. Washer 10, spring 11, screw 12 from the inside of mirror body 2
The mirror housing 3 is rotatably crimped onto a bearing 9 of a mounting bracket 8 fixedly attached to the mirror housing 3. And the mounting bracket 8 is
It is fixed to a boss 6 protruding from the inner surface of the mirror housing 3 by a screw 7, and is disposed in the opening of the mirror housing 3 together with the mirror 1 and the mirror body 2. In addition, 5 is a base formed to fix the mirror housing 3 to the vehicle body.

That is, as described above, the structure in which the mirror 1 is gripped by the mirror body 2 rotatably pressed and held on the bearing 9 is such that the mirror body 2 is held by the washer 1.
0. After the spring 11 and the screw 12 are used to press and hold the mirror 1 on the bearing 9,
The mirror 1 is held by the mirror body 2 by being press-fitted into a fitting groove 2a formed on the inner peripheral edge of the mirror body 2 by undercut molding. Generally, the peripheral edge of the mirror body 2 is heated to slightly deform the peripheral edge to facilitate press-fitting of the mirror 1.

Furthermore, the mirror 1 held by the mirror body 2
The mirror body 2 is tightly gripped in the fitting groove 2a of the mirror body 2, and the flat part 2b formed adjacent to the fitting groove 2a is brought into contact with the back surface of the mirror 1. This prevents vibration within the 2. However, in the conventional example described above, the mirror 1 is press-fitted into the fitting groove 2a of the mirror body 2, or the fitting groove 2a is formed by undercut molding. It was molded from a material that easily deforms, such as synthetic resin such as polypropylene. Therefore, in tropical regions, the mirror body 2 may sometimes become deformed when subjected to rapid temperature changes that often occur in cold regions. Furthermore, the mirror 1 has a fitting groove 2 in the mirror body 2 to prevent the image from flickering due to vibration.
Since the mirror body 2 is tightly gripped by the mirror body 2a and the flat part 2b, the deforming force of the mirror body 2 is immediately applied to the mirror 1, deforming the mirror 1 and causing distortion to the mirror surface, which may distort the image in the rear view. , there were cases where visibility was deteriorated.

In view of the above-mentioned circumstances, the present invention is such that the peripheral portion of the mirror body 2 that press-fits and holds the mirror 1 is made of a relatively easily deformable material such as polypropylene, and the main body portion is made of a rigid metal or synthetic resin. For example, by forming the mirror body with glass-containing resin, etc., the mirror body can be prevented from deforming.
It is an object of the present invention to provide a mirror for an automobile in which distortion is prevented from occurring on the mirror surface of the mirror 1.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the drawings, components corresponding to those of the conventional example will be described using the same reference numerals.

4 to 6 show the first embodiment of the present invention, in which FIG. 4 is a cross-sectional view, FIG. 5 is an omitted plan view, and FIG. 6 shows the fitted state of the mirror. It is a sectional view of the main part shown.

As shown in FIG. 4, the mirror body 2 that holds the mirror 1 has a concave part 21c in the center that bulges out to the rear side and has a holding part 21a with the mirror housing 3 having a through hole 21b at the top thereof. A flat engagement hole 21 formed on the periphery of the recessed portion 21c
Mirror contact surface 21d and mirror contact surface 2 having f
A ring 22 made of soft synthetic resin is integrally molded on a mirror body main body having a peripheral wall 21e bent forward on the peripheral edge of 1d, and a front wall having a mirror pressing part 22b protruding inward on the peripheral wall 21e. 22a, a peripheral wall 21e, an outer peripheral wall 22c surrounding the outside, and an inner peripheral wall 22d surrounding the inside. The mirror body 2 configured as described above is connected to the bearing 9 by a washer 10, a spring 11, a screw 12, etc. as in the past. After the ring 22 of the mirror body 2 is heated and expanded slightly, the ring 22 is press-fitted.
The mirror pressure contact portion 22b of the mirror body 2 is clamped and held between the mirror contact surface 21d of the mirror body 2. Note that 1a is an adhesive tape that prevents displacement and vibration between the mirror 1 and the mirror body 2, and also prevents glass from scattering when the mirror 1 is broken.

Therefore, the main body portion of the mirror body, which occupies most of the mirror body 2 that clamps and holds the mirror 1, is integrally molded with a rigid material such as a rigid plate, and around the periphery is made of a relatively soft material such as synthetic resin such as polypropylene. Since the ring is press-fitted, the mirror body 21 will not be deformed even if there is a sudden change in temperature in cold or tropical regions, and therefore the mirror 1 will not be distorted and visibility will not deteriorate. I won't force you.

In addition, since the ring 22, which is the part of the mirror body 2 into which the mirror 1 is press-fitted, is molded from soft synthetic resin, it is easy to press-fit the mirror 1, and it is also easy to assemble the ring 22 to the mirror body main body 21. .

By providing a gap between the peripheral edge 1b of the mirror 1 and the peripheral wall 21e of the mirror body main body 21, a slight expansion on the periphery of the mirror 1 itself is allowed, and the adhesive tape 1a allows the mirror to There is no direct contact with the body 2, and no electrical contact occurs on the mirror 1 and corrodes the reflective film (not shown) of the mirror 1.

Since the ring 22 is molded integrally with the mirror body main body 21 in the mold, the mirror body 2 that can be fixed firmly and easily can be molded easily and inexpensively.

7 and 8 show another embodiment of the present invention, in which the ring 22 of the first embodiment is integrally molded with the mirror body main body 21.
A holding part 13 that adjustably holds the mirror housing on the mirror housing is integrally attached with synthetic resin, and a connecting part 22e between the through hole 21b and the mirror body 21 is formed.

In this embodiment, the holding portion 13 has an arbitrary shape.
can be fixed to the mirror body main body 21 very easily, so the mirror body main body 21 can be formed in common, and the holding part 13 can be changed to be used commonly for a normal mirror, a remote control type mirror, etc. The compatibility of body 2 has increased, and the cost of mirror body 2 has decreased due to mass production.
This also has the effect of reducing the cost of the mirror itself.

As is clear from the embodiments described above, the present invention provides an automobile mirror comprising a mirror body that holds a mirror, a mirror housing that adjustably holds the mirror body, and a base that fixes the mirror housing to the vehicle body. The mirror body 2 has a recessed part in the center that has a holding part with the mirror housing, a mirror contact surface formed around the recessed part and an engagement hole bored therein, and a front surface on the periphery of the mirror contact surface. A mirror body main body is provided with a peripheral wall bent in a direction, and the peripheral wall portion is integrally molded with a soft synthetic resin to form a front wall having an inwardly projecting mirror pressure contact portion, an outer peripheral wall, and an inner peripheral wall. Since the mirror body is surrounded by a portion of the mirror body and the outer circumferential wall and the inner circumferential wall are connected through an engaging hole, the mirror body is The mirror body 2 of the mirror 1 has good visibility without being deformed and causing distortion in the mirror 1.
It has the advantage of being easy to press fit into the mirror body, and the molding of the mirror body itself is extremely simple as it is integrally molded, and the mirror body can be used in common with other types of mirror products, thus reducing costs. It also has advantages such as being inexpensive.

It should be noted that, as a matter of course, the present invention is not limited to the embodiments described above.
