JPS62101561A - Rearview mirror used as room lamp in common - Google Patents

Abstract

PURPOSE:To enable the use of a rearview mirror in common with a room lamp by applying a semi-transparent mirror for main mirror constitution and providing an illuminant behind the main mirror. CONSTITUTION:A main mirror 1 is so provided in a box 3 and comprises a semi-transparent mirror. An illuminant 5 is provided behind the main mirror 1 in the box 3 and connected to a door switch 8 via a lead wire through the hollow part of a stay 6. The rearview mirror so constituted can be used as common to a room lamp by turning the switch 8 'ON'.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a rear-view mirror installed in an interior of an automobile, and particularly relates to a rear-view mirror installed in an automobile, which also serves as an interior light. It is.

[Prior Art] Conventionally, the rearview mirror and the interior lamp of this scale were installed separately, with the rearview mirror placed in the width section of the ceiling of the car, and the interior light placed in the center of the same ceiling. ), but in recent years it has been called the sliding sunroof and
The one in which part of the t-section moves rearwards to form an opening is popular in the market, and various automobile manufacturers are responding to the market by preparing vehicle models equipped with the sliding sunroof. However, in this case, since the above-mentioned interior light cannot be installed in the center of ceiling #1, an example of installing it at the +'+ff end of the ceiling where the room mirror is installed is used. There are many. In addition, conventional rearview mirrors include a primary mirror only (f not shown) and an anti-glare type as shown in Figure 4. In this case, a semi-transparent primary mirror 1 and a total reflecting mirror 112 are arranged on the same image body 3 at a constant angle. Said i
The body 3 is provided with a hinge 4 that rotates the hook body 3 at a fixed angle at a cam machine drawing Z, 7, etc. in a normal state such as daytime, as shown in Fig. 4 (^). As shown in , the reflected light L1 of the tangential light LO by the primary mirror 1 reaches the 81 field of operation, passes through the main 5lli, is reflected by the secondary mirror 2, and then passes through the primary mirror 1 again. The reflected light L2 from the side R2 is directed in a direction that does not reach the driver's field of view. However, at night,
For example, if a following vehicle follows you with its headlights still in its running beam, the driver will be dazzled, so the hinge 4 will rotate the
Then, as shown in FIG. 4(B), the reflected light L2 of the n1 mirror 2
reaches the driver's field of vision.

As explained above, the reflected light L2 is 11% of the semi-transparent
1 twice, so for example, the above ]-mirror 1
If the transmittance of is 30%, then 0.3X O,3=0.09
According to the calculation, the brightness of the reflected light L2 according to l'IQ is
It becomes 9% of the light LO and provides an anti-glare effect.

[Problems to be Solved by the Invention] However, moving the interior light to the front end of the ceiling in order to install the above-mentioned sliding sunroof means that the above-mentioned sliding sunroof is This means that it is necessary to prepare two types of ceiling parts, one with a sliding sunroof and one without.As a result, vehicles equipped with the sliding sunroof are It requires an assembly process and parts arrangement, which creates a very complicated management problem, and is called head clearance because the interior light is installed above the head of the car user. This has resulted in problems such as a reduction in the headroom of 17 rooms, impairing comfort, and a problem that the cost is too high compared to the benefits obtained by automobiles equipped with the sliding sunroof.

Means for Solving Problem E] The present invention provides a rearview mirror installed in the interior of an automobile as a specific means for solving the above-mentioned conventional problems, in which the primary mirror of the rearview mirror is It is a semi-transparent mirror,
By providing a room mirror that also serves as an interior light, characterized in that a light emitting part is disposed on the rear side of the primary mirror,
This solves the above problem by standardizing the interior lights.

[Example] Next, the present invention will be described in detail based on an example shown in the drawings. In order to facilitate understanding, the same parts as in the conventional example will be described with the same reference numerals.

Figures 1 and 2 show an example in which the present invention is applied to a rearview mirror with only the primary mirror 1, and the primary mirror 1 is numbered in the i-body 3 as in the conventional example. 110 reporter 1111
For example, a semi-transparent mirror with a reflectance of 50% is used instead of a total reflection type, and as shown in Fig. 2, the main vL
On the back side of 1, that is, inside the image body 3, an arbitrary number of lights #
A light source 5 is connected to a door switch 8 provided at the door of the vehicle by a lead wire 7 through the hollow part of the support column 6.

Although omitted in the drawings to clearly show the basics of the present invention, there is a switch that turns on and off the light source 5 independently of the door switch 8, or a switch that turns the light source 5 on and off independently of the door switch 8, or when the door switch is opened (when the door is It goes without saying that installation of an afterglow circuit to keep the light source 5 on for a certain period of time after the light source 5 is closed can be implemented using conventional, well-known techniques.

What is shown in FIG. 3 is an example in which the present invention is applied to an anti-glare mirror having a primary mirror 1 and a secondary mirror 2.
A four part 3A is formed in the picture body 3 above the middle part of the image body 3, and an arbitrary number of light sources 5 are disposed in the recess 3A. Even better results can be obtained if the shape is designed to efficiently reflect the light rays emitted by 5. With this configuration, the light rays emitted by the light source 4 directly pass through the primary mirror 1 and are emitted by the light 881.82, and after being reflected by the secondary mirror 2, pass through the main chain 1 and become b'113I. The light rays S 1 and S 2 are generated and are appropriately diffused. In this embodiment, the electrical wiring of the -b light source 4 is exactly the same as that of the embodiment with only the primary mirror 1 described above. ! J? I will omit the explanation because it is too late.

[Function] According to the present invention, J.S. Rearview mirror 1: The mirror is semi-transparent and a light beam is provided on the back side of the mirror, so that when the door of the car is opened, the light source is turned on and the primary mirror is illuminated. The light that passes through illuminates the interior of the vehicle and acts as an interior light.

[5? Effect of bright light] As explained in detail above, by making the primary mirror of the rearview mirror semi-transparent, installing a light source on the back side of the mirror, and using the rearview mirror as an interior light, the door of the car can be illuminated. Related to driving, such as opening and closing dynamics When there is no need for an illuminated rearview mirror, it operates as an interior light, and when driving it operates exactly the same as a conventional rearview mirror. Hf1 with sliding 1y roof
It is possible to share parts between vehicles equipped with a sliding sunroof and those without it, simplifying management aspects such as processes and parts arrangement, and for users to ensure sufficient head clearance even in vehicles equipped with the sliding sunroof. The Qin 1J has excellent practical effects such as providing comfortable living.
