Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view for explaining a configuration example of a vehicle window glass according to an embodiment. As shown in FIG. 1, the vehicle window glass 1 according to the present embodiment includes a glass plate 10, a light-shielding portion 13, bus bars 11 and 12, a plurality of heater wires 15, and lamps 21 and 22. The vehicle window glass 1 according to the present embodiment can be typically used for the rear glass of the vehicle. However, the vehicle window glass 1 according to the present embodiment may be used in any place other than the rear glass.

The glass plate 10 is a glass plate for a vehicle, and may be a laminated glass in which two glass plates are bonded together via an interlayer film, or may be a single glass plate. The glass plate 10 shown in FIG. 1 has a trapezoidal shape, but the shape of the glass plate 10 can be appropriately changed depending on the place where the glass plate 10 is attached. For example, the glass plate 10 may have a shape in which four corners and four sides have curvatures. Further, the glass plate 10 itself may have a curvature. In this case, the glass plate 10 has a "single bend" shape having a curvature in one direction (eg, x-axis direction or y-axis direction), or in two orthogonal directions (eg, x-axis direction and y-axis direction). It may be a "double bend" shape with curvature.

The light-shielding portion 13 is provided around the glass plate 10. Specifically, the light-shielding portion 13 is formed along the outer periphery of the glass plate 10. The light-shielding portion 13 is formed on the surface of the glass plate on the minus side in the z-axis direction. The light-shielding portion 13 is a member that shields visible light. When the light-shielding portion 13 is provided, when the glass plate 10 is attached to the vehicle, the attachment portion and the like are less likely to be visually recognized from the outside of the vehicle, so that the design of the vehicle is improved. Further, the bus bars 11, 12, 41, and 42 are also difficult to be visually recognized from the outside of the vehicle, so that the design of the vehicle is improved. As shown in FIG. 1, the region of the glass plate 10 in which the light-shielding portion 13 is not formed is a transmission region 14 capable of transmitting visible light.

The bus bar 11 is provided along the side of the outer circumference of the glass plate 10 on the minus side in the x-axis direction. Specifically, the bus bar 11 overlaps with the light-shielding portion 13_1 on the minus side in the x-axis direction of the light-shielding portion 13 provided on the outer periphery of the glass plate 10, and the light-shielding portion 13_1 extends in the extending direction (longitudinal direction). It is provided along the line.

The bus bar 12 is provided along the positive side in the x-axis direction of the outer circumference of the glass plate 10. Specifically, the bus bar 12 overlaps with the light-shielding portion 13_2 on the plus side in the x-axis direction (in other words, the light-shielding portion 13_1 facing the light-shielding portion 13_1) among the light-shielding portions 13 provided on the outer periphery of the glass plate 10. As such, it is provided so as to be along the extending direction (longitudinal direction) of the light-shielding portion 13_2.

A plurality of heater lines 15 extend between the bus bar 11 and the bus bar 12. The plurality of heater wires 15 have a function as a defogger that generates heat when an electric current flows and heats the glass plate 10. Power is supplied to the plurality of heater lines 15 from the bus bar 11 and the bus bar 12. For example, when the bus bar 11 is connected to the ground potential and the bus bar 12 is connected to a predetermined power supply potential (plus potential), the plurality of heater wires 15 are connected to the plurality of heater wires 15 from the bus bar 12 toward the bus bar 11 (minus side in the x-axis direction). (Towards) current flows. On the contrary, when the bus bar 12 is connected to the ground potential and the bus bar 11 is connected to a predetermined power supply potential (plus potential), the plurality of heater wires 15 are connected to the plurality of heater wires 15 from the bus bar 11 toward the bus bar 12 (plus in the x-axis direction). Current flows (towards the side). In the following, a case where the bus bar 11 is connected to the ground potential and the bus bar 12 is connected to a predetermined power supply potential (plus potential) will be described as an example.

The lamps 21 and 22 are provided on the glass plate 10. The lamp 21 is provided on the bus bar 11 side (minus side in the x-axis direction), and the lamp 22 is provided on the bus bar 12 side (plus side in the x-axis direction). The lamps 21 and 22 have built-in light emitting elements 23 and 24 that emit light by supplying power, respectively. For the light emitting elements 23 and 24, for example, an LED (Light Emitting Diode), an organic EL element, or the like can be used. The lamps 21 and 22 are, for example, a tail lamp, a stop lamp, a reverse lamp, a turn signal lamp, and the like.

In the vehicle window glass 1 according to the present embodiment, the lamps 21 and 22 are attached to, for example, the inner surface of the glass plate 10 (that is, the surface on the negative side in the z-axis direction of the glass plate) (see FIG. 2). ). By attaching the lamps 21 and 22 to the surface of the glass plate 10 in this way, the glass 10 can be expanded to the area where the conventional lamp is installed. As a result, the transmission region 14 of the glass plate 10 can be widened, whereby a wide field of view of the rear part of the vehicle can be secured. Further, by integrating the lamps 21 and 22 into the glass plate 10, the design of the vehicle can be improved.

In the configuration example shown in FIG. 1, the negative terminals of the lamps 21 and 22 (light emitting elements 23 and 24) are arranged on the negative side in the y-axis direction, and the positive terminals of the lamps 21 and 22 (light emitting elements 23 and 24) are arranged in the y-axis direction. It is placed on the plus side. In other words, in the present embodiment, the lamps 21 and 22 (light emitting elements 23 and 24) are arranged so that the polarities are aligned in the y-axis direction.

Further, the negative terminals of the lamps 21 and 22 are connected to the feeder line 31. Since the feeder line 31 is connected to the bus bar 11, a ground potential is supplied to the negative terminals of the lamps 21 and 22 via the feeder line 31. Further, the feeder line 31 includes a portion extending in a direction parallel to the plurality of heater lines 15 (x-axis direction). In FIG. 1, the lamps 21 and 22 are shown in a perspective view in order to illustrate the arrangement of the feeder lines 31 and the like. The same applies to other drawings.

The positive terminal of the lamp 21 is connected to the feeder line 32. The feeder line 32 is connected to the bus bar 41. The bus bar 41 is provided in the vicinity of the bus bar 12 independently of the bus bar 12. Since the positive power potential is supplied to the bus bar 41, the positive power potential is supplied to the positive terminal of the lamp 21 via the feeder line 32. As a result, the lamp 21 lights up. Further, the feeder line 32 includes a portion extending in a direction parallel to the plurality of heater lines 15 (x-axis direction).

The positive terminal of the lamp 22 is connected to the feeder line 33. The feeder line 33 is connected to the bus bar 42. The bus bar 42 is provided in the vicinity of the bus bar 12 independently of the bus bar 12. Since the positive power potential is supplied to the bus bar 42, the positive power potential is supplied to the positive terminal of the lamp 22 via the feeder line 33. As a result, the lamp 22 lights up. Further, the feeder line 33 includes a portion extending in a direction parallel to the plurality of heater lines 15 (x-axis direction).

Each terminal of the lamps 21 and 22 (light emitting elements 23 and 24) and the feeder lines 31 to 33 can be connected by a conductive member such as a solder, a spring, or a wire. These conductive members may be used alone or in combination.

In the configuration example shown in FIG. 1, since the feeder lines 32 and 33 are connected to the positive terminals of the lamps 21 and 22, respectively, the lamps 21 and 22 can be controlled independently. Therefore, in the configuration example shown in FIG. 1, in addition to the tail lamp, the stop lamp, the reverse lamp, etc. that light the lamps 21 and 22 synchronously, the turn signal lamp that lights (blinks) the lamps 21 and 22 independently is also used. Available. When the lamps 21 and 22 are blinked, for example, switching control is performed in a power supply control circuit (not shown) connected to the bus bars 41 and 42.

FIG. 2 is a cross-sectional view of the vicinity of the lamp 22 of the vehicle window glass 1 according to the present embodiment, and shows a cross-sectional view of the lamp 22 cut along a cutting line extending in the y-axis direction. As shown in FIG. 2, the lamp 22 is attached to the surface of the glass plate 10 on the minus side in the z-axis direction (the surface inside the vehicle). The lamp 22 is attached at a predetermined distance from the surface of the glass plate 10. That is, since the lamp 22 is attached so as to form a gap between the lamp 22 and the glass plate 10, the feeding line 32 can be arranged between the lamp 22 and the glass plate 10.

For example, the lamp 22 can be attached to the surface of the glass plate 10 by providing an adhesive member (not shown) between the lamp 22 and the glass plate 10. In the vehicle window glass 1, for example, a cover member (not shown) is provided on the inner surface of the glass plate 10 (that is, the surface on the minus side in the z-axis direction of the glass plate), and the lamp 22 includes the cover member and the glass plate 10. It may be sealed between. As shown in FIG. 2, the lamp 22 has a built-in light emitting element 24, and power is supplied to the light emitting element 24 via the feeder lines 31 and 33. The lamp 21 has the same configuration as the lamp 22.

In the vehicle window glass 1 according to the present embodiment, the plurality of heater wires 15, and the feeder lines 31, 32, 33 are, for example, a paste containing a conductive metal (for example, silver paste) on the glass plate 10. It may be formed by printing on the surface and baking. Further, the plurality of heater wires 15, and the feeder wires 31, 32, 33 may be formed by attaching a linear body or a foil-like body containing a conductive material such as copper to the surface of the glass plate 10. The bus bars 11 and 12 and the bus bars 41 and 42 can also be formed by the same method.

The plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 may be made of the same material. By using the same material in this way, the design of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 can be improved. Further, the thicknesses of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 may be substantially the same. By making the thicknesses of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 substantially the same in this way, the design can be further improved. Here, substantially the same means that the standard deviation of the line width is 1 mm or less. The standard deviation of the line widths of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 is preferably 0.5 mm or less, more preferably 0.1 mm or less.

In this embodiment, the material of a part of the wiring of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 may be the same. Further, the thickness of some of the plurality of heater wires 15 and the plurality of feeder lines 31, 32, 33 may be the same. Further, in the present specification, the heater line 15, the feeder line 31, 32, 33, and the bus bars 11, 12, 41, 42 may be collectively referred to as “wiring”.

As described above, in the vehicle window glass 1 according to the present embodiment, the power supply terminals of the lamps 21 and 22 are connected to the common feeder line 31, and the feeder line 31 is connected to the bus bar 11. Further, the feeder line 31 includes a portion extending in a direction parallel to the plurality of heater lines 15. With such a configuration, even when the lamps 21 and 22 are provided on the glass plate 10, it is possible to prevent the wiring (feeding line) from becoming complicated.

That is, in the present embodiment, the lamps 21 and 22 are arranged so that the polarities are the same. Then, the terminal of one polarity of the lamps 21 and 22 is connected to the feeder line 31, and the terminal of the other polarity is connected to the feeder lines 32 and 33. With such a configuration, it is possible to prevent the arrangement of the feeder lines 31, 32, 33 for supplying power to the lamps 21, 22 from becoming complicated. In particular, in the present embodiment, since the terminal of one polarity of the lamps 21 and 22 is connected to the common feeder line 31, the number of feeder lines can be reduced and the arrangement of the feeder lines becomes complicated. It can be suppressed.

Further, in the present embodiment, at least a part of each feeder line 31, 32, 33 is configured to be parallel to the heater line 15. Therefore, even when the feeder lines 31, 32, and 33 are additionally arranged on the glass plate 10, the consistency with the plurality of heater lines 15 for the defogger can be obtained, and the design of the window glass 1 for the vehicle can be improved. Can be improved.

Further, in the present embodiment, the bus bars 41 and 42 for supplying power to the feeder lines 32 and 33 are arranged in the vicinity of the bus bars 12 having the same polarity. Specifically, the bus bars 41 and 42 to which the positive power potential is supplied are arranged in the vicinity of the bus bar 12 to which the positive power potential is also supplied. Therefore, since the potential difference between the respective bus bars 12, 41, and 42 can be reduced, short-circuiting between the bus bars can be suppressed.

Further, in the present embodiment, as shown in FIG. 1, a conductive wire (dummy wiring) 61 may be provided between the feeder line 31 and the feeder line 32. The dummy wiring is a conductive wire that does not supply power to the lamps 21 and 22. The conductive wire 61 has a portion parallel to the feeder line 31 and the feeder line 32, and is arranged so as not to come into contact with at least one of the feeder line 31 and the feeder line 32. That is, the conductive wire 61 may be arranged so as to be in contact with either one of the feeder line 31 and the feeder line 32, or may be arranged so as not to be in contact with both the feeder line 31 and the feeder line 32. The configuration example shown in FIG. 1 shows an example in which the conductive wire 61 is not in contact with both the feeder line 31 and the feeder line 32. By providing the conductive wire 61 between the feeder line 31 and the feeder line 32 in this way, the design of the vehicle window glass 1 can be improved.

Further, in the present embodiment, as shown in FIG. 1, it is sandwiched between a line 51 that is substantially parallel to the bus bar 11 and passes through the lamp 21 and a line 52 that is substantially parallel to the bus bar 12 and passes through the lamp 22. In the region 55 (that is, the central region), the intervals d1 to d4 of the adjacent lines may be substantially the same. Specifically, the distance d1 between the heater wire 15 closest to the lamp 21 and the heater wire 15 closest to the lamp 21, the distance d2 between the heater wire 15 and the feeder line 32, and the feeder line 32 and the conductive wire 61. The interval d3 and the interval d4 between the conductive wire 61 and the feeder line 31 may be substantially the same. With such a configuration, the design of the vehicle window glass 1 can be improved.

Note that substantially parallel means that the angle formed by the bus bar 11 and the line 51 and the angle formed by the bus bar 12 and the line 52 are each within the range of about 0 ° to 15 °. Further, substantially the same means that the standard deviation of the intervals d1 to d4 is 10 mm or less. The standard deviation of the intervals d1 to d4 is preferably 6 mm or less, more preferably 4 mm or less, still more preferably 2 mm or less. Further, in the present embodiment, the distance between the heater wires 15 may be substantially the same as the distance d1 to d4.

Further, in the present embodiment, the distance between the heater wires 15 on the side closer to the lamps 21 and 22 and the distance between the heater wires 15 on the side farther from the lamps 21 and 22 (plus side in the y-axis direction) are set to be different. You may. For example, the distance d1 between the heater wires 15 on the side closer to the lamps 21 and 22 may be wider than the distance d5 between the heater wires 15 on the side farther from the lamps 21 and 22 (plus side in the y-axis direction). ..

Further, in the present embodiment, the thicknesses of the heater wire 15, the conductive wire 61, and the feeder wires 31 and 32 may be substantially the same. By making the thicknesses of the heater wire 15, the conductive wire 61, and the feeder wires 31 and 32 substantially the same in this way, the designability can be further improved. Here, substantially the same means that the standard deviation of the line width is 1 mm or less. The standard deviation of the line widths of the heater wire 15, the conductive wire 61, and the feeder wires 31 and 32 is preferably 0.5 mm or less, more preferably 0.1 mm or less.

Further, in the present embodiment, conductive wires (dummy wirings) 62 and 63 may be provided on the bus bar 11 side. For example, the conductive wire 62 may be provided on an extension of the feeder line 32. Further, the conductive wire 63 may be provided on an extension of the conductive wire 61. That is, even in the region on the minus side in the x-axis direction with respect to the wire 51, the intervals between the plurality of heater wires 15 and the conductive wires 62 and 63 may be substantially the same. Further, in the present embodiment, the intervals between the plurality of heater wires 15 and the feeder wires 32 and 33 may be substantially the same even in the region on the plus side in the x-axis direction of the wire 52. Thereby, the design of the window glass 1 for a vehicle can be further improved.

FIG. 3 is a front view for explaining another configuration example of the window glass for a vehicle according to the present embodiment. In FIG. 3, the same components as those of the vehicle window glass 1 shown in FIG. 1 are designated by the same reference numerals.

In the vehicle window glass 2 shown in FIG. 3, the negative terminals of the lamps 21 and 22 are connected to the feeder line 31. Since the feeder line 31 is connected to the bus bar 11, a ground potential is supplied to the negative terminals of the lamps 21 and 22 via the feeder line 31. Further, the feeder line 31 includes a portion extending in a direction parallel to the plurality of heater lines 15 (x-axis direction).

Further, the positive terminals of the lamps 21 and 22 are connected to the feeder line 34. The feeder line 34 is connected to the bus bar 43. The bus bar 43 is provided in the vicinity of the bus bar 12 independently of the bus bar 12. Since the positive power potential is supplied to the bus bar 43, the positive power potential is supplied to the positive terminals of the lamps 21 and 22 via the feeder line 34. As a result, the lamps 21 and 22 are turned on. Further, the feeder line 34 includes a portion extending in a direction parallel to the plurality of heater lines 15 (x-axis direction).

In the configuration example shown in FIG. 3, the negative terminals of the lamps 21 and 22 are connected to the common feeder line 31, and the feeder line 31 is connected to the bus bar 11. Further, the positive terminals of the lamps 21 and 22 are connected to the common feeder line 34, and the feeder line 34 is connected to the bus bar 43. As described above, in the configuration example shown in FIG. 3, the negative terminals of the lamps 21 and 22 are connected to the common feeder line 31, and the positive terminals of the lamps 21 and 22 are connected to the common feeder line 34. The number of feeder lines can be reduced, and the complicated arrangement of feeder lines can be suppressed more effectively. For example, the vehicle window glass 2 shown in FIG. 3 can be used as a tail lamp, a stop lamp, a reverse lamp, or the like that simultaneously lights the lamps 21 and 22.

Further, also in the vehicle window glass 2 shown in FIG. 3, a conductive wire 61 may be provided between the feeder line 31 and the feeder line 34. FIG. 3 shows a configuration example in which both ends of the conductive wire 61 are overlapped with the lamp 21 and the lamp 22. In the present embodiment, both ends of the conductive wire 61 may be arranged so as to overlap with at least one of the lamp 21 and the lamp 22, and as shown in FIG. 1, both ends of the conductive wire 61 may be arranged with the lamp 21 and the lamp 22. It may be configured so as not to overlap with the lamp 22.

Further, in the present embodiment, the conductive wire 61 may form an antenna capable of receiving radio waves in a frequency band such as a broadcast wave. When the conductive wire 61 is used as an antenna, for example, the feeder line 60 for the antenna is extended to the conductive wire 61 through the gap (see FIG. 2) between the lamp 22 and the glass plate 10 shown in FIG. It is connected to the conductive wire 61. The feeder line 60 is connected to the feeder unit 44 for the antenna. The feeding unit 44 may have, for example, a configuration in which an internal conductor (core wire) of a coaxial cable (not shown) is electrically connected and a signal is received by an amplifier (not shown). In this case, the outer conductor of the coaxial cable is grounded to the body of the vehicle. With such a configuration, the signal from the antenna including the conductive wire 61 can be received via the feeding unit 44 while ensuring the design of the window glass 2 for the vehicle.

Further, as the antenna, in addition to the conductive wire 61, for example, the feeder line 34 may be capacitively coupled to the feeder line 34 and used as an antenna for receiving a broadcast wave or the like. Examples of the broadcast wave include radio waves in the FM broadcast wave (88 MHz to 108 MHz) frequency band, radio waves in the Band III (174 MHz to 240 MHz) frequency band of the European standard DAB (Digital Audio Broadcast), and the like.

Further, in the present embodiment, at least a part of the plurality of heater wires 15 (defogger) may be overlapped with at least one of the lamp 21 and the lamp 22. With such a configuration, it is possible to suppress the glass plate 10 from fogging at the position where the glass plate 10 overlaps with the lamps 21 and 22, and the light of the lamps 21 and 22 can be easily transmitted.

Further, with reference to FIG. 4, another configuration example of the window glass for a vehicle according to the present embodiment will be described. The configuration example of FIG. 4 is different from the configuration example of FIG. 1 in that the polarities of the lamps 21 and 22 are reversed in the y-axis direction. Other than this, it is the same as the configuration example shown in FIG. In the vehicle window glass 3 shown in FIG. 4, the same components as those of the vehicle window glass 1 shown in FIG. 1 are designated by the same reference numerals.

In the vehicle window glass 3 shown in FIG. 4, the negative terminals of the lamps 21 and 22 are arranged on the positive side in the y-axis direction, and the positive terminals of the lamps 21 and 22 are arranged on the negative side in the y-axis direction. Also in the configuration example shown in FIG. 4, the polarities of the lamps 21 and 22 are arranged so as to be aligned in the y-axis direction.
