Abstract

The present invention provides a glass plate module to be attached to a vehicle. The glass plate module includes laminated glass in which an outer glass plate, an interlayer, and an inner glass plate are layered in this order; a mask layer that is provided on the laminated glass and blocks a field of vision from outside; and an attachment member that is attached to a portion corresponding to the mask layer on the inner glass plate with at least a first adhesion means and a second adhesion means and configured to support an information acquisition device for acquiring information from outside of a vehicle. The first adhesion means includes adhesive at at least one location. The second adhesion means is configured such that the adhesive conducts preliminary fixing prior to curing. The attachment member includes a fixation portion that faces the mask layer and has a bonding surface provided with the adhesion means. The fixation portion includes at least one adhesive confirmation portion through which the adhesive applied to the bonding surface can be seen from the vehicle interior side.

Claims (55)

1. A glass plate module to be attached to a vehicle, the glass plate module comprising:

laminated glass in which an outer glass plate, an interlayer, and an inner glass plate are layered in this order;

a mask layer that is provided on the laminated glass and blocks a field of vision from outside; and

an attachment member that is attached to a portion corresponding to the mask layer on the inner glass plate with at least a first adhesion means and a second adhesion means and configured to support an information acquisition device for acquiring information from outside of the vehicle,

wherein the first adhesion means includes adhesive at at least one location,

the second adhesion means is configured such that the adhesive conducts preliminary fixing prior to curing,

the attachment member includes a fixation portion that has a bonding surface facing the mask layer and provided with both of the adhesion means,

the fixation portion includes at least one adhesive confirmation portion through which the adhesive applied to the bonding surface can be seen from the vehicle interior side,

the adhesive confirmation portion is constituted by a cutout formed at an edge of the fixation portion,

the adhesive confirmation portion is disposed over both a portion in which the adhesive is present and a portion in which the adhesive is not present,

the second adhesion means includes at least one piece of double-sided adhesive tape having a thickness of 0.2 mm or more and 0.8 mm or less, and

at least a portion of a region to which the adhesive is applied or a spread-out region of the adhesive overlaps with the cutout on the bonding surface.

2. The glass plate module according to claim 1 ,

wherein the adhesive confirmation portion is constituted by a through hole formed in the fixation portion, and

at least a portion of a region to which the adhesive is applied and a spread-out region of the adhesive intersects the through hole on the bonding surface.

3. The glass plate module according to claim 2 ,

wherein the adhesive is applied in a linear manner to intersect the through hole, and

the through hole is formed to have an external shape in which a length in a first direction in which the adhesive extends is smaller than a length in a second direction that intersects the first direction at a right angle.

4. The glass plate module according to claim 1 , wherein the adhesive is applied in a linear manner so as to pass near a position that is farthest from an outer edge of the fixation portion.

5. The glass plate module according to claim 4 , wherein the cutout is formed in an arc shape.

6. The glass plate module according to claim 1 ,

wherein when applied to the bonding surface, the adhesive is constituted by a main portion and an extended portion that extends from the main portion to an edge of the fixation portion or a vicinity of an edge of the fixation portion, and

the adhesive confirmation portion is constituted by a portion at an edge of the fixation portion, which is reached by the extended portion.

7. The glass plate module according to claim 6 ,

wherein the main portion is formed to extend in one direction, and

a length in the extended portion in a direction in which the main portion extends is smaller than a length of the main portion.

8. The glass plate module according to claim 1 , wherein the mask layer is made of a dark-colored ceramic layer.

9. A method for manufacturing a window module provided with an information acquisition device for acquiring information from outside of a vehicle, the window module being configured to be attached to the vehicle, the method comprising:

a step of preparing a glass plate module including:

laminated glass in which an outer glass plate, an interlayer, and an inner glass plate are layered in this order;

a mask layer that is provided on the laminated glass and blocks a field of vision from outside; and

an attachment member that is attached to a portion corresponding to the mask layer on the inner glass plate with at least a first adhesion means and a second adhesion means and supports the information acquisition device, and

a step of installing the information acquisition device on the inner glass plate side via the attachment member,
