Abstract

PURPOSE:To prevent the rise of vehicle interior temperature caused by solar radiation and a peep from the outside by forming liquid crystal films on window glass plates for the front-rear windows and door part windows of an automobile, and regulating supply voltage to the films. CONSTITUTION:Glass plates formed by disposing liquid crystal 15, transparent films 13, 17, transparent electrodes 14, 16 in the laminated state at a glass plate 12 is used as the window glass plates of front and rear windows and door part windows. Voltage supply from a battery to the transparent electrodes 14, 16 of these glass plates is controlled through a switch and a controller. The transparency of the glass is thereby changed according to the circumstances so as to prevent solar radiation into the vehicle interior and a peep from the outside of a vehicle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile in which glass can be freely made transparent or dark.

[0002]

2. Description of the Related Art Conventional automobile glass is transparent, and it is necessary to attach a black film when it is desired to darken the glass.

[0003]

This method has the following drawbacks. (1) The method of sticking a black film is not perfect because there are restrictions on where it can be stuck. (2) On the other hand, if the glass is transparent, the sunlight will penetrate into the car and the car will get hot. (3) If the glass is transparent, there is a danger that others will be able to peek inside the car. The present invention has been made to eliminate this drawback.

[0004]

[Means for Solving the Problem] The front window (1), the wind glasses (5) (6) (7), and the rear window (9) are liquid crystal (15) on the glass (12) shown in FIG.
The transparent films (13) and (17) containing the are attached, or the glass (18) and the glass (22) shown in FIG.
Liquid crystal (20) is inserted between the windows, and each window (1) (5) (6) (7) (9) has a switch (8). From this switch (8) Signal is sent to the controller (10), and the controller (10) supplies each window (1) (5) (6) (7) (9) from the battery (11) by the signal from the switch (8). It decides whether to apply the applied voltage.

[0005]

Operation: By the switch (8), the transparent electrode (1
4) (16) or the transparent electrodes (19) (2) of FIG.
The voltage can be applied between 1) to make the liquid crystal (15) or (20) transparent or dark respectively, so by pressing the switch (8), you can make the window transparent at any time and look outside. Or you can darken the window to prevent the sun from setting.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a structural example of the present invention. In the windows (1), (5), (6), (7) and (9), the liquid crystal film (1) containing the liquid crystal (15) in the glass (12) shown in FIG.
3) The one to which (17) is attached, or the glass (18)
A liquid crystal (20) between (22) and the like are used, and the operation is the same. Also, each window is provided with a switch (8), and the signal from this switch (8) is transmitted to the controller (10) to determine whether to supply the voltage from the battery (11). First, with the car parked and the key removed,
It is assumed that no voltage is supplied to each window and the liquid crystal is in a dark state. By doing this, while the car is parked, the sun will not light up and the inside will not be damaged by the high temperature, and no one can look inside. Also, the battery will not go dead. Next, when you try to drive the car and insert the key into the key slot (3), the controller (10)
Then, the voltage is applied to all the windows to make them transparent. Then, when it is desired to darken the window during driving, the switch (8) is used. When the window at the door is darkened while driving, the portion (5) where the line of sight crosses the windshield so that the door mirror (4) can be seen from the driver's seat can be independently controlled by a switch. .

[0007]

【The invention's effect】

(1) The glass of the car can be freely darkened or made transparent, so that depending on the situation you can see the outside scenery, prevent the sun from shining inside the car, and prevent others from seeing inside the car. You can (2) It is possible to prevent the inside of the car from getting hot and the inside of the car being damaged by the high temperature due to the sunlight coming into the car while it is parked.
