Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a vehicle rearview mirror device for viewing the rear from the driver's seat of a vehicle.

(Prior Art) For example, an automobile is always provided with a fender mirror or a door mirror as a rear view mirror device, and FIG. 2 shows an example of a conventional door mirror. In FIG. 2, reference numeral 1 denotes a mirror body formed by plating a metal such as chromium on the back surface of a glass substrate, and is configured as a plane mirror (or a convex mirror with a large radius of curvature). Further, 2 is a mirror holder for rotatably supporting the mirror body 1, and 3 is a housing for storing the mirror body 1 and the mirror holder 2.

(Problem to be solved by the invention) In this case, the above door mirror is installed near the driver's seat, and the mirror body is configured as a plane mirror (or a convex mirror similar to this). Therefore, in bright surroundings such as during the daytime, the facial expressions of the driver of the vehicle or the situation inside the vehicle can be easily seen by the occupants of the following vehicle through the mirror body. There was a problem that the privacy of people could easily be invaded. Especially in recent years, when the number of cars equipped with door mirrors has increased,
Many users, mainly women, are hoping for a solution to these problems.

The present invention was developed in view of the above circumstances, and its purpose is to make it difficult to see the situation inside the vehicle from the rear through the mirror body, and to make it difficult to see the rear view from the vehicle interior through the mirror body. An object of the present invention is to provide a rear view mirror device for a vehicle which has effects such as allowing the vehicle to be seen clearly and realizing such a function with a simple structure that does not involve power consumption.

[Structure of the invention] (Means for solving the problem) The vehicle rear view mirror device according to the invention has a half body housed in a housing so as to reflect the rear view, and a half mirror. A light regulating filter is disposed on the back surface of the mirror body, and a lighting window is formed in the housing so as to face the back surface of the light regulating filter, and the light from the lighting window is directed rearward by the light regulating filter. The feature is that it is configured so that only the guide is guided.

(Function) The position of the mirror body is adjusted so that the driver inside the vehicle can see the rear scenery using the reflected image. At this time, when the surroundings are bright such as during the day, the external light that enters the housing through the lighting window is guided only backwards through the light adjustment filter and the mirror body made of a half mirror. does not reach the driver inside the vehicle. Therefore, the reflected image of the mirror body seen by the driver is not affected by light from the lighting window, and the driver can clearly see the scenery behind him through the mirror body. On the other hand, when looking at the mirror body from behind under such circumstances, a reflected image of the interior of the vehicle will be reflected on the mirror body, but the light from the above-mentioned lighting window will be superimposed on the reflected image. As a result, it becomes difficult to see the situation inside the vehicle from the rear through the mirror body.

(Example) Hereinafter, an example in which the present invention is applied to a door mirror of an automobile will be described with reference to FIG. 1.

In FIG. 1, 4 is a flat mirror body made of a half mirror, and 5 is a light adjustment filter attached to the back of this mirror body 4. It is configured to guide light only in one direction.

Reference numeral 6 denotes a mirror holder for supporting the mirror body 4 and the light adjustment filter 5, and this has a relatively large-area through hole 6a facing the back side of the light adjustment filter 5.
is formed. The mirror holder 6 is constructed as one unit together with the mirror body 4 and the like, and is rotatably supported by a mirror housing 7 attached to the door of the automobile.

In the mirror housing 7, a plurality of light-transmitting windows 8 are provided on the back surface of the light regulating filter 5.
As a result, the light from the lighting window 8 is projected onto the back side of the light adjustment filter 5 through the light transmission 6a. Furthermore, 9
is a transparent plate fitted into the lighting window 8.

In the above configuration, the position of the unit including the mirror body 4, the light adjustment filter 5, etc. is adjusted so that the driver inside the vehicle can see the rear scenery through the reflected image of the mirror body 4. At this time,
In bright surroundings, such as during the day, the lighting window 8
As mentioned above, the external light that enters the mirror housing 7 through the filter is guided only rearward through the light adjustment filter 5 and the mirror body 4 made of a half mirror, and the light reaches the driver inside the vehicle. The light is blocked by the light regulating filter 5.

Therefore, the reflected image of the mirror body 4 seen by the driver is not affected by the light from the lighting window 8 in any way, and the driver can see the scenery behind the mirror body 4.
can be clearly seen through. On the other hand, when looking at the mirror body 4 from behind, a reflected image of the interior of the vehicle is reflected on the mirror body 4, but the light from the lighting window 8 is superimposed on the reflected image, and its contrast is starts to decrease.

In other words, according to the configuration of the present embodiment described above, it becomes difficult to see the inside of the vehicle from the rear through the mirror body 4 in bright surroundings such as during the daytime, and it becomes difficult to see the interior of the vehicle from the rear through the mirror body 4. This eliminates the possibility that the driver's expression or the situation inside the vehicle will be easily seen by the occupants of the following vehicle through the mirror body 4.

In addition, as a result of using the configuration that uses external light as described above, there is no need to provide a separate light source, which has the advantage of simplifying the structure and eliminating power consumption at all.Moreover, there is no risk of failure. There are some things that can be almost eliminated and reliability can be improved.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, and may be implemented with various modifications without departing from the gist, for example, it may be applied not only to door mirrors but also to room mirrors. It is something that can be done.

[Effects of the invention] According to the present invention, as is clear from the above explanation, it becomes difficult to see the inside of the vehicle from the rear through the mirror body, which makes it possible to protect privacy. The rear view can now be seen clearly through the mirror body, and it has the beneficial effect of realizing such a function with a simple and highly reliable structure that does not consume electricity. It is.
