Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a turnover type elastomer door mirror in which the mirror body is formed of an elastomer.

[Prior Art] Recently, door mirrors attached to doors have been widely used. By the way, this kind of door mirror is superior to fender mirrors in terms of appearance and visibility, but on the other hand, the tip of the mirror body protrudes to a large extent from the outermost line of the car, so the door mirror is There is a risk that it may come into contact with objects and cause an accident.

In order to prevent such accidents, for example, in the European EC region, as shown in Figures 4 and 5, a steel ball W with a diameter of 175 mm is inserted into the outermost line L of the car from a 60° angle position with a radius of 1 m. A hammer test standard has been established to confirm that the steel ball W swings down toward the front and back surfaces of the door mirror along the direction of the mirror body, causes the mirror body to fall down, and then passes forward or backward. The same applies to all imported cars.

By the way, in such a test, when the mirror body 1 falls forward, the mirror body abutment part 3 that comes into contact with the mirror base 2 collides with the mirror base front edge 2a, so in a normal door mirror, the mirror body 1 and the mirror Base 2 is damaged. Therefore, in the mirror body 1 of the door mirror to which such a test is applied, when the mirror body 1 collides with the mirror base 2, it is necessary that the mirror body abutting portion 3 is deformed in a concave manner to buffer the impact. On the other hand, it is also required to have a certain degree of rigidity and shape retention. In order to satisfy these conditions, the mirror body 1 is usually made of elastomer, which prevents damage to the mirror and also avoids deformation of the mirror due to wind pressure during high-speed driving.

[Problems to be Solved by the Invention] However, such conventional elastomer door mirrors still have the following problems, particularly in terms of cushioning properties.

In other words, the outer surface of a mirror body made of elastomer is also decorated with elastomer-based paint, but conventional elastomer mirror bodies have sufficient deformation cushioning properties and shape retention properties. Therefore, when the mirror body falls down and collides, the buffer deformation is not uniform, and the decorative paint is often damaged. As a result, the beauty of the mirror was impaired and the overall product image of the vehicle was degraded.

Therefore, an object of the present invention is to provide a turnover type elastomer door mirror that has sufficient deformation buffering properties and also has sufficient shape retention properties.

[Means for solving the problem] In order to achieve this objective, the turnover type elastomer door mirror of the present invention includes a mirror base that is attached to the door and an elastomer mirror body that is supported by the mirror base so that it can be folded forward and backward. This is a turnover-type elastomer door mirror consisting of a mirror body having a thin wall thickness at a portion that contacts a mirror base when the elastomer mirror body is folded down.

[Operation] Since the deformation buffering properties of the contact portion of the mirror body are improved, the mirror body is not damaged in the event of a collision. Further, since the shape retention of the mirror body is maintained at a predetermined value, the mirror is not deformed.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, the same parts as in the conventional example are given the same reference numerals, and their explanations will be omitted.

In FIGS. 1, 2, and 3, the turnover type elastomer door mirror is constructed such that an elastomer mirror body 1 is supported by a mirror base 2 attached to a door so as to be foldable in the front and rear directions, and the present invention In the door mirror according to the invention, a wall thickness ta at a contact portion 3 of the mirror body 1 with the mirror base 2 is formed to be thinner than a wall thickness tb at other portions. Here, the thickness ta
are mirror body 1 and mirror base 2 of contact area 3
The wall thickness tb is formed to have a sufficient thickness to provide sufficient deformation buffering properties in the event of a collision with the mirror body, and the wall thickness tb is formed to a sufficient thickness to maintain the shape retention of the mirror body. Note that reference numeral 5 denotes a reinforcing frame screwed to a support protrusion 4 provided on the mirror body 1, and a mirror holder 6 holding a mirror 7 is pivotally supported on this reinforcing frame 5.

In such a configuration, during a hammer test or the like, the mirror body 1 collides its contact portion 3 with the front edge 2a of the mirror base 2, but at this time, the contact portion 3 is uniformly and smoothly deformed into a concave shape. Since the impact is buffered, not only the main body of the mirror body 1 but also the decorative paint will not be damaged. Further, although a strong external force is applied to the mirror body 1 due to wind pressure during high-speed driving, the mirror body 1 has sufficient shape retention, so that the mirror body 1 is not deformed.

Although the embodiments have been described with respect to elastomer door mirrors, it goes without saying that the present invention can be similarly applied to door mirrors of the same type, such as hard rubber door mirrors.

[Effects of the invention] As explained above, the turnover-type elastomer door mirror of the invention has a thinner wall thickness at the portion of the mirror body formed of elastomer that contacts the mirror base. It improves the deformation buffering properties of the mirror body without reducing shape retention, so the mirror will not be deformed even by strong wind pressure, and at the same time prevents damage to the mirror in the event of a toppling collision. be able to.
