Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an interior mirror that is attached to the windshield of a passenger car or the like.

[Prior Art] FIG. 3 is an explanatory diagram showing an example of an inner mirror M used by being attached to a windshield F.

This inner mirror M has a stay S equipped with a base B that is fixed to the windshield F, and a mirror body R is attached to the pivot (not shown) of this stay S.
is rotatably mounted.

As an example of the above-mentioned inner mirror M, this inner mirror M is an auto-dimming mirror that reduces glare by attenuating reflected light from a mirror surface when it senses a certain amount of light or more.

That is, this inner mirror M connects power from a battery (not shown) to a light sensor or the like disposed at an appropriate position via an electric wire (flat cable or the like).

When this optical sensor detects the amount of light, it drives the EL or LCD etc. on the reflecting mirror.
By controlling an image display device that functions as a type of light absorber that changes the reflectance of light, reflected light is attenuated and reflected light from a mirror surface is reduced.

This prevents the driver from being dazzled by light reflected from the interior mirror even when driving at night or through a tunnel, thereby ensuring visibility during driving.

Therefore, the above-mentioned auto-dimming type inner mirror M is equipped with signals to control and drive signals when an optical sensor is placed on the mirror body or when an ECD, EL, LCD, etc. are placed on the back side of the mirror surface. It is necessary to supply current for this purpose.

To do this, as shown in the drawing, an electric wire L placed on the roof of the vehicle, etc. is connected to the stay S, and a current is led from this electric wire to the EL, LCD, etc. placed at an appropriate position such as inside the inner mirror M. ing.

Further, the base B is fixed to the indoor side of the windshield F with an adhesive.

[Problems to be Solved by the Invention] In the conventional example, the electric wires connected to the stays are exposed from the ceiling, and the design is unsightly and undesirable.

In addition, electric wires and the like obstruct the view, and in addition, the electric wires are directly connected to the stays, which may prevent the mirror from falling off.

Therefore, the present invention solves the above problems by improving the current and signal connection mechanism in the inner mirror.

[Means for solving the problem] The present invention provides a modulation/AC converter connected to a DC power source on the roof of a vehicle, and a signal input/output interface connected to a control computer. Install a demodulation circuit.

A base member connected to the modulation/demodulation circuit and provided with a pattern of coils or electrodes is disposed within the windshield.

On the other hand, inside the mirror body, a demodulation/modulation circuit with an AC/DC converter and a signal input/output interface is arranged, and at the base of the stay that supports the mirror body, there is a coil or electrode connected to the base of the stay. A patterned joining member is provided.

Further, in the vehicle window adhesive type interior mirror of the present invention, the mirror body is fixed by bonding a joining member at a position facing the base member across the front window.

[Operation of the invention] The current supplied from the battery, which is a DC power source, is converted into alternating current by the DC/AC converter and then supplied to the modulation/demodulation circuit.

On the other hand, output signals from a computer that manages the current state of the vehicle via various sensors are input to the modulation/demodulation circuit via the signal input/output interface.

This modulation/demodulation circuit generates a modulated wave containing various information, which is guided through wiring in the windshield to the base member on which the coil or electrode pattern is formed.

On the other hand, the base of the stay that supports the inner mirror is provided with the above-mentioned coil or electrode pattern, and the above-mentioned modulated wave is transmitted to this pattern using glass as a dielectric material, and a transformer and a capacitor are formed between each electrode. A modulated wave is transmitted and guided to a modulation/demodulation circuit within the mirror body via an energized line.

The demodulated signal sends a control signal to an EL, LCD, etc. via a signal input/output interface, and the light transmittance is changed to adjust the shading and the like.

Since the electric wires are extremely thin and are routed inside the windshield, the design is improved and the mirror attached to the stay easily falls off when it falls off.

[Embodiment] FIG. 1 is an explanatory diagram showing an embodiment of the present invention, and FIG. 2 is a block diagram of the same.

As an example, a DC/AC converter 1 is disposed within a roof R of a vehicle C, one end is connected to a DC power source (not shown), and the other end is connected to an input end of a modulation/demodulation circuit 2.

In addition to the DC/AC converter 1, the modulation/demodulation circuit 2 is connected to a signal input/output interface 3.

Further, the other end of the modulation/demodulation circuit 2 is connected to a connector C provided on the sealing material of the windshield F.

In addition, the windshield F is, for example, a laminated glass made by bonding two pieces of glass with an adhesive film or the like, and a thin current-carrying wire 4 connected to the coil or electrode is wired on the laminated surface by an appropriate means. do.

A base member 5, which has a rectangular shape and has a pattern forming a coil or an electrode, is disposed at the end thereof.

On the other hand, the stay 6, which rotatably supports the mirror body M on a pivot, has a coil or electrode pattern similar to that described above on its base, and is provided with a bonding member 7 that adheres to the glass surface.

Furthermore, the current-carrying wire 8 from the bonding member 7 is connected to a modulation/demodulation circuit 9 disposed on the mirror body M.

The demodulation/modulation circuit 9 has an AC/DC converter 10 and a signal input/output interface 11 installed in parallel, and transmits current and control signals to an EL (not shown).
Or supply it to an image display device such as an LCD.

As described above, the glass-bonded inner mirror of the present invention converts control signals into modulated waves, uses glass as a dielectric, and uses transformers and capacitors to transmit information to the mirror body. Transmits current.

[Effects of the invention] As mentioned above, the invention has internal wiring connected to the vehicle's power supply, control computer, etc. in the laminated glass, and also faces the electrodes arranged at the base of the stay that supports the mirror body. Since the electrodes were installed,
It has a luxurious design that is incomparable to those with exposed wiring connected to the stay.

Furthermore, in the event of an emergency, the mirror can easily fall off the windshield without dragging the wiring as in the case of the conventional mirror, making it a highly safe and useful invention for industrial use.
