DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrochromic anti-glare mirror for controlling the brightness of reflected light by electrically coloring an electrochromic film provided on the front side of a reflection film.

[0002]

2. Description of the Related Art In a vehicle mirror installed on a vehicle, a so-called electrochromic anti-glare mirror for adjusting the brightness of reflected light by electrically developing an electrochromic film provided on the back side of a substrate glass. There is.
In this electrochromic antiglare mirror, for example, a transparent conductive film is provided on the back surface of the substrate glass, and an electrochromic film is provided on the back surface of the transparent conductive film. A reflective conductive film such as aluminum is provided on the back surface of the electrochromic film, and an electrochromic layer is formed by the transparent conductive film, the electrochromic film, and the reflective conductive film. A protective plate made of glass, metal, or the like is adhered to the back surface of the electrochromic layer with a sealing adhesive, and the electrochromic layer is protected by the protective plate.

Here, this electrochromic anti-glare mirror has a pair of electrochromic anti-glare terminals, one of which is in contact with the substrate glass and the transparent conductive film and the other of which is the electro-chromic anti-glare terminal. Is in contact with the substrate glass and the reflective conductive film. Wiring (hereinafter referred to as “electrochromic anti-glare wiring”) for supplying a current between the transparent conductive film and the reflective conductive film is formed by a code on the pair of electrochromic anti-glare terminals. A pair of electrodes (hereinafter, referred to as “electrochromic antiglare electrodes”) are connected to the glare wiring. By supplying power from the electrochromic anti-glare electrode to the transparent conductive film and the reflective conductive film through the electrochromic anti-glare wiring, the space between the transparent conductive film and the reflective conductive film is formed through the electrochromic film. To make the electrochromic film electrically colored. Thereby, the brightness of the light reflected by the electrochromic anti-glare mirror is adjusted.

Further, a fail-safe resistor is wired in the code complete of the electrochromic anti-glare wiring, and the fail-safe resistor causes a failure in the power supply for supplying power between the transparent conductive film and the reflective conductive film. Then, the electric charge between the transparent conductive film and the reflective conductive film is discharged. As a result, the fail-safe resistor acts to force the electrochromic anti-glare mirror back to the daytime mode, with the electrochromic film in a state where it cannot develop color.

A heater is provided on the back surface of the protection plate. The heater is provided with a pair of heater terminals, and the heater generates heat by energizing between the pair of heater terminals. Wiring for energizing the pair of heater terminals (hereinafter referred to as “heater wiring”) is connected to the pair of heater terminals.
), And a pair of electrodes (hereinafter, referred to as “heater electrodes”) are connected to the heater wiring. By supplying power between the pair of heater electrodes via the heater wiring from the pair of heater electrodes,
Electric current is applied between the pair of heater terminals to cause the heater to generate heat.
As a result, the heater heats the substrate glass to remove the fogging of the electrochromic anti-glare mirror.

However, in such an electrochromic anti-glare mirror, a cord is used for the electro-chromic anti-glare wiring and the wiring for the heater, so that a complicated code routing operation is required. For this reason, not only is erroneous assembling likely to occur, but also the assemblability is poor and the number of work steps is large, resulting in high costs. Further, since this cord is attached to the back side of the heater with a butyl tape or the like, the thickness of the electrochromic antiglare mirror is increased, and the space for accommodating the electrochromic antiglare mirror is increased. Furthermore, since the cord moves during the mirror surface adjustment, the cord is easily pinched.

Further, since a fail-safe resistor is required to be wired in the code complete of the electrochromic anti-glare wiring, and the fail-safe resistor is required to be wound with a waterproof tape, the number of parts and the number of working steps are increased. And this results in high costs.

[0008]

In view of the above facts, the present invention not only prevents erroneous assembly by using a circuit board for wiring for electrically coloring the electrochromic film, but also enables It is an object of the present invention to provide an electrochromic anti-glare mirror capable of improving the attachment property and reducing the number of work steps to reduce the cost.

According to the electrochromic anti-glare mirror of the first aspect, a conductor (hereinafter, referred to as a conductor) for supplying an electric current between the transparent conductive film and the reflective conductive film of the electrochromic layer.
An electrochromic antiglare conductor is provided on a circuit board, and electric power is supplied between the transparent conductive film and the reflective conductive film through the electrochromic antiglare conductor, thereby forming the transparent conductive film and the reflective conductive film. Electric current is passed between the film and the film through the electrochromic film, so that the electrochromic film is colored electrically. Thereby, the brightness of the light reflected by the electrochromic anti-glare mirror is adjusted.

Here, since the conductor for electrochromic anti-glare is provided on the circuit board, a complicated cord handling work such as wiring by a conventional cord is not required. For this reason,
Not only can erroneous assembly be prevented, but also the assemblability can be improved and the number of man-hours can be reduced, thereby reducing costs. Further, since the electrochromic anti-glare conductor can be made thin, the electrochromic anti-glare mirror can be made thin to save space. Furthermore, since the electrochromic anti-glare conductor can be fixed to the circuit board by printing or the like, it is possible to prevent the electrochromic anti-glare conductor from being pinched during mirror adjustment.

In the electrochromic anti-glare mirror according to the second aspect, when the power supply for supplying power between the transparent conductive film and the reflective conductive film fails in the electro-chromic anti-glare mirror according to the first aspect, A fail-safe resistor for discharging electric charge between the transparent conductive film and the reflective conductive film is provided on the circuit board.

According to the electrochromic anti-glare mirror of the second aspect, the fail-safe resistor provided on the circuit board is used when the power supply for supplying power between the transparent conductive film and the reflective conductive film fails. The electric charge between the transparent conductive film and the reflective conductive film is discharged. As a result, the fail-safe resistor acts to force the electrochromic anti-glare mirror back to the daytime mode, with the electrochromic film in a state where it cannot develop color.

Here, since the fail-safe resistor is provided on the circuit board, it is not necessary to wire the fail-safe resistor in the code complete of the electrochromic anti-glare wiring unlike the prior art. Since there is no need to perform a process of winding the waterproof tape, the number of parts and the number of man-hours can be reduced, and the cost can be reduced.

According to a third aspect of the present invention, there is provided the electrochromic antiglare mirror according to the first or second aspect, wherein the transparent substrate is heated by generating heat by energizing the pair of terminals. A heater is provided between the electrochromic layer and the circuit board, and the pair of terminals is directly connected to the circuit board.

According to the electrochromic anti-glare mirror of the third aspect, the pair of terminals of the heater are directly connected to the circuit board, and by supplying power between the pair of terminals through the circuit board, the pair of terminals is connected. The heater is heated by energizing the terminals. As a result, the heater heats the transparent substrate to remove the fogging of the electrochromic anti-glare mirror.

Here, since the pair of terminals of the heater are directly connected to the circuit board, a conventional cord for connecting the heater terminal and the heater electrode can be dispensed with. For this reason, complicated code handling work as in the related art is not required, and not only can erroneous assembly be further prevented, but also the assemblability can be improved and the number of work steps can be reduced, thereby further reducing the cost. Therefore, the electrochromic anti-glare mirror can be made thinner to save more space, and the cord can be prevented from being pinched when the mirror surface is adjusted.

Although a transparent substrate is provided on the front side of the electrochromic layer, the material of the transparent substrate is not limited to glass, and may be, for example, plastic, and a configuration in which the transparent conductive film of the electrochromic layer also serves as the transparent substrate. Good. Further, it is also possible to use a transparent conductive film as the reflective conductive film of the electrochromic layer, and to provide the reflective film separately from the electrochromic layer. Further, as a method of providing a conductor or a fail-safe resistor on the circuit board, various methods such as printing, etching, and bonding can be applied.
