Description

Description Vehicle mirror Technical field

The present invention relates to a vehicle mirror having improved visibility of an image reflected on a mirror on a passenger seat side. Background art

As a conventional example for improving the visibility of vehicle mirrors, by increasing only the horizontal curvature to the vertical curvature of the convex mirror used for the rearview mirror, the width of the following vehicle can be seen to be somewhat congested. This results in a wide angle, eliminating the conventional disadvantage of blind spots on the right and rear, and the same curvature as before, so the height of the car looks the same as before. What can be confirmed with the same feeling as in the past is described in Japanese Patent Application Laid-Open No. H10-287686.

In addition, the donut mirror is used as an objective mirror, and the flat mirror is used as a judge's mirror, and they are arranged close to each other to obtain a wide viewing angle. Japanese Unexamined Patent Publication No. Hei 11-0-788698 discloses a vehicle in which the situation of an acute-angle intersection road on the rear side can be reliably viewed from the driver's seat, and can be arranged in a vehicle and used safely. ing.

In addition, the conventional rear view mirror is used to eliminate blind spots in the car side mirror (door mirror) and create a mirror surface for the car side mirror (door mirror) that enables comfortable and safe driving. Reduce the area of this part slightly, and bend the mirror right side 3 outward to capture the blind spot diagonally right behind the driver's seat (right side). Furthermore, Japanese Patent Application Laid-Open No. 2000-2966737 discloses an example in which the lower right portion 5 of the mirror surface is bent outward to capture the blind spot at the lower right rear portion.

Further, in the conventional vehicle, as shown in FIG. 4, the vehicle 1 is provided with mirrors 2 and 3 on the left and right for a driver to check behind. The mirror surfaces of the left and right mirrors 2 and 3 have the same curvature of R620 as a general standard. Therefore, as shown in Fig. 5, in the case of a vehicle with the driver's seat on the right side, it is far from the driver's viewpoint. The image S 2 shown on the left-hand side mirror 3 on the passenger side of the vehicle appeared to be smaller than the image S 1 shown on the right-side mirror 2.

Therefore, it was difficult to grasp distance recognition and image recognition because it was recognized that the size of the image at the same distance was different from right to left and it was farther than it actually was. .

In addition, the curvature of the general part is changed downward (gradual change) in the range of about one-third of the entire curved mirror with a one-sided configuration to secure the indirect visibility range at the foot.

Therefore, the indirect visibility range on the left side of the vehicle expanded in the width direction as the distance from the iris increased, and the indirect visibility range in the width direction of the foot was narrow, and the curvature of the general part was changed downward (gradual change). The mirror has a problem that image distortion occurs and it is difficult to recognize the image.

There is no mirror that solves the above-mentioned problems, and in the past, only a wide-angle mirror for eliminating the rear blind spot was provided, and there was a mirror that solved the above-mentioned problems. Did not.

BEST MODE FOR CARRYING OUT THE INVENTION

The best mode for carrying out the present invention will be described below with reference to the drawings.

The passenger seat is on the left when the driver's seat is on the right, and on the right when the driver's seat is on the left. The following description is for the left vehicle mirror when the driver's seat is on the right and the passenger seat is on the left, but the same applies to the right vehicle mirror when the driver's seat is on the left and the passenger seat is on the right. is there.

In FIGS. 1 and 2, reference numeral 10 denotes a mirror body on the passenger side, and reference numeral 11 denotes a mirror body. P 1 is a passenger side mirror.

In the present invention, when the mirror on the driver's seat side is D, the radius of curvature R P1 of the mirror P 1 on the passenger seat side is such that the radius of curvature R D of the mirror D on the driver's seat side is R P 1> RD. The difference in the radius of curvature between the passenger side mirror P 1 and the driver side mirror D should be within 15% of the size of the image shown on the passenger side mirror P 1 and the image shown on the driver side mirror D. The radius of curvature that is set is desirable.

For this purpose, when the radius of curvature of the driver's seat side mirror D is set to R62.0, the radius of curvature of the passenger side mirror P1 is set to R100.

As a result, there is no left-right difference in the size of the images at the same distance, so that distance recognition and image recognition can be accurately grasped. In addition, the radius of curvature of the driver side mirror D is R620, and the passenger side mirror P is When the radius of curvature of 1 is set to R100, the existing curvature can be used, so that the cost can be reduced.

Further, as shown in FIGS. 1 and 2, the present invention relates to a vehicle having a driver's seat on the right side on the left side, and a vehicle having a driver's seat on the left side, and a right passenger's seat side mirror P 1 having a radius of curvature PR 1 and driving. The radius of curvature D of the hand side mirror D is set to RP 1> RD, and the image shown in the passenger side P 1 is made larger than the image shown in the driver side mirror 1 D, and at the lower side of the passenger side mirror P 1. An auxiliary mirror P2 is provided, and the radius of curvature RP2 of the auxiliary mirror P2 and the radius of curvature RD of the driver side mirror D are set to RP2 <RD.

For example, the radius of curvature of the auxiliary mirror P2 may be R200. In this case, investment and cost can be reduced by using existing equipment. By setting the above auxiliary mirror P2 The side view is enlarged, and the blind spot can be reduced.

In addition, when the passenger side mirror P1 is arranged at a regular position, as shown in FIG. 3 (C), the auxiliary mirror P2 has its vehicle side field of view in the vehicle front area X from the eye point y. Is arranged so that is obtained.

It is desirable that the auxiliary mirror P2 be positioned so as to cover the range of visibility d from the left side of the vehicle to the full width 3.25 m of one lane when the lane is changed from the vehicle front and rear position of the eye point y.

Further, according to the present invention, the auxiliary mirror P2 is provided with a pivot so that its mirror surface angle can be changed.

As a result, the field of view of the auxiliary mirror P2 can be arbitrarily selected on the basis of the iris point, and the blind spot in the vicinity can be covered.

Fig. 3 is a comparison diagram of the visibility range of the passenger side mirror P1 and the auxiliary mirror P2 with various radii of curvature.

In FIGS. 3 (A), 3 (B) and 3 (C), reference numeral 4 denotes a steering wheel, and the radius of curvature of the driver's seat side mirror D is R620 in any case.

First, Fig. 3 (A) shows the current passenger-side mirror, which is the main body with a radius of curvature R620, and gradually changes to a radius of curvature R620-300 below the passenger-side mirror P1. The auxiliary mirror P 2 is set as an integral mirror.

In this case, the images appear to be connected, but there is a problem that the subject (image) is small and the distortion of the subject (image) is large.

Note that a is the range of view of the passenger side mirror P1, and c is the range of view of the auxiliary mirror P2.

In Fig. 3 (B), the radius of curvature of the passenger side mirror P1 is R100, and the radius of curvature of the auxiliary mirror P2 below it is gradually changed from R100 to R300. In this case, it is set as an integral mirror.

In this case, since RP 1> RD for the radius of curvature R 6 20 of the driver's seat side mirror D, the image S 2 of the passenger side mirror P 1 and the image S 1 of the driver side mirror D The difference in size can be reduced, and discomfort and false recognition are reduced. In this case, the size of the image is 50% larger than that in FIG. 3 (A), and the difference between the image and the mirror D on the driver's seat side is 14% smaller.

According to the evaluation, the size of the image S 1 of the mirror D on the driver's seat side and the image S 2 of the mirror P 1 on the passenger seat have a remarkable effect within 15% of soil.

Furthermore, the visibility range b of the passenger side mirror P1 and the visibility range d of the auxiliary mirror P2 decrease with respect to the visibility ranges a and c in Fig. 3 (A), but the reduction is allowable up to 50%. Area. In this case, as in FIG. 3 (A), the images of the passenger side mirror P1 and the auxiliary mirror P2 appear to be connected.

In Fig. 3 (C), the radius of curvature of the passenger side mirror P1 is R100, and the radius of curvature of the lower auxiliary mirror P2 is set at a constant R200. This is an example of a form in which a boundary 12 between P1 and an auxiliary mirror P2 is separated by, for example, a width of 5 mm.

In this case, similarly to FIG. 3 (B), misrecognition can be improved, and if RP1 is set to 100, it can be set using existing equipment, so that equipment investment can be reduced.

In addition, the indirect field of view in the width direction of the feet, and the field of view d at the lower part of the front passenger side, which is necessary when turning to the passenger seat side, shall be constant without a gradual change in the radius of curvature. By doing so, a wide field of view without image distortion can be secured.

If RP 2 is set to 200, this visibility range d can be further widened, and the radius of curvature is possible with existing equipment, so that capital investment can be reduced to reduce costs. Thus, the visibility can be improved by expanding the indirect view range without impairing the current direct view range.

When the passenger side mirror P1 is set to the normal position, the setting position of the separate auxiliary mirror P2 is the range X including the front of the vehicle from the eye point y which is the driver's eye position. With d, indirect visibility can be further improved.

If the pivot is dedicated to the auxiliary mirror P2, the orientation of the auxiliary mirror P2 can be arbitrarily changed, and there is an advantage that the degree of freedom of the visibility range is further increased.

Therefore, even with the mirrors in Figs. 3 (B) and 3 (C), the subject (image) looks larger than in Fig. 3 (A), the size of the left and right images is uniform, and the sense of distance and the visibility of the image are improved. ing.

In the case of Fig. 3 (C) above, a one-sided curvature changing (gradual changing) mirror as shown in Fig. 3 (B) is used. On the other hand, the width of the indirect field of view in the width direction of the feet on the auxiliary seat side is expanded.

In addition, it has a further advantage that visibility can be improved without impairing the direct view range because the indirect view range is expanded by forming a two-plane mirror within the current mirror size range. Industrial applicability

In the vehicle mirror according to the present invention, a sense of incongruity and an accurate sense of distance arising from the difference in the size and distance of the object due to the size of the image reflected on both mirrors due to the difference in distance between the driver side mirror, the passenger side mirror and the eye point. Since there is no erroneous recognition of images and images, and the effect of improving visibility by expanding the indirect field of view without impairing the current direct field of view, the industrial applicability is extremely large.

Note that the present invention is not limited to the above embodiment.
