Description

[Detailed Description of the Invention] [Industrial field of application] The present invention can secure the view of the side view of the door mirror and the vehicle body,
The present invention relates to an automobile door glass that is improved so that the wave reception performance can also be improved.

[Conventional technology]

It has been generally known that a rear windshield of an automobile is printed with a heat ray for removing fog to secure a rear view and an antenna wire for receiving an FM broadcast (Japanese Utility Model Publication No. 58-59613). , JP-A-62-253289).

Further, in order to improve the visibility of the door mirror, it has been generally known that the heat ray printing is limited to the front part of the door glass (see Japanese Utility Model Laid-Open No. 61-7460).

[Problems to be solved by the device]

By the way, in the conventional example in which the antenna wire is printed only on the rear windshield, the conventional method is applied from the front-back direction of the vehicle.
There was a problem that the reception gain decreased for FM waves and it was difficult to obtain a stable and good reception condition.

Further, in the conventional example in which the heat ray print is applied only to the front portion of the door glass, there is a problem in that the field of view on the side of the vehicle body cannot be sufficiently secured.

Therefore, an object of the present invention is to provide a vehicle door glass that can secure a field of view including a door mirror on the side of a vehicle body and can improve FM wave reception performance.

[Means for Solving the Problems]

For this purpose, the present invention relates to a rear window glass having a heat ray print also serving as an antenna and a vehicle door glass including a door mirror, in which the upper portion of the door glass is fixed glass including a portion where the door mirror can be seen through. The method is to provide a hot wire print that also serves as an antenna on the entire surface.

[Action]

In the automobile door glass of the present invention employing such means, the fixed glass on the upper portion of the door glass, including the portion where the door mirror can be seen through, heats up over the entire surface due to the energization of the heat wire print that also serves as the antenna, Cloudiness is removed.

Further, the FM diversity antenna is composed of the antenna combined heat ray print of the rear window glass and the antenna combined heat ray print provided on the fixed glass above the door glass.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the automobile shown in FIG. 1, a rear window glass 1 is provided with a heat wire print 2 which also serves as an antenna, and its door 3
A door mirror 4 is attached to the.

The door 3 has a sash, and its upper edge sash 5a
A partition sash 5b that extends in the front-rear direction substantially in parallel with is provided between the door panel 3a. The upper part between the partition sash 5b and the upper edge sash 5a, that is, the door mirror 4
A fixed glass 6a is fitted in an upper portion including a portion immediately after the door mirror 4 through which the glass can be seen, and an elevating glass 6b is installed in a lower portion between the partition sash 5b and the door panel 3a.

Here, the fixed glass 6a has a three-dimensional curved surface adapted to the car body shaping in consideration of car design and aerodynamic characteristics, and has a shape that extends to the roof portion of the car body.

The fixed glass 6a is provided with a heat ray print 7 also serving as an antenna on the entire surface thereof. In this case, the heat ray print 7 also serving as the antenna is 0.8 m to the heat ray print 2 also serving as the antenna on the rear window glass 1.
They are about 1 m apart and are in a perfect positional relationship with the diversity antenna, and both form the FM diversity antenna.

On the fixed glass 6a, a film member whose transparency changes by energization is attached so as to cover the heat ray print 7 also serving as the antenna. In this case, the film member is configured as a circuit by changing the voltage with the above-mentioned hot wire print 7 which also serves as an antenna, or as a separate circuit.

In the above configuration, the temperature of the fixed glass 6a is raised over the entire surface by energizing the hot wire print 7 that also serves as the antenna.
Even if the entire surface is fogged or water drops are attached,
These can be removed. Therefore, the door mirror 4 and the side of the vehicle body can be clearly seen from the driver's seat through the fixed glass 6a, and safety is ensured.

When the heat wire print 7 that also serves as an antenna is used as an antenna wire, an excellent FM diversity antenna is configured together with the heat wire print 2 that also serves as the antenna on the side of the rear window glass 1 as described above, and the FM wave reception performance is improved. Greatly improved.

Further, by energizing the film member of the fixed glass 6a, its transparency changes, so that the fixed glass 6a is shaded.
It is possible to improve the light shielding property of the portion.

[Effect of device]

As described above, according to the present invention, the fixed glass on the upper part of the door glass, including the part where the door mirror can be seen through, is heated over the entire surface by energizing the heat wire print that also serves as the antenna, so that the entire surface of the fixed glass is removed. It is possible to secure the field of view including the door mirrors on the side of the vehicle body.

Further, since the FM diversity antenna is composed of the antenna combined heat ray print of the rear window glass and the antenna combined heat ray print provided on the fixed glass above the door glass, the FM wave reception performance can be improved.
