Onboard device and attachment structure for onboard device
An onboard device includes a body member, a support member projecting from the body member and including a base to be attached to a concave inner surface of a glass member having a curved shape provided in a vehicle, and a double-sided adhesive tape stuck on a the base. The base is a plate-like member including an attachment surface to be opposed to the inner surface of the glass member. The attachment surface is a curved surface having a curvature at least in a first direction along the attachment surface. The double-sided adhesive tape is provided with at least one first slit open toward an upper edge located on the upper side and cut downward and at least one second slit open toward a lower edge located on the lower side and cut upward when the base ( 3 ) is attached to the inner surface.
1. An onboard device comprising:
a body member;
a support member projecting from the body member and including a base to be attached to a concave inner surface of a glass member having a curved shape provided in a vehicle; and
a double-sided adhesive tape prepared to be stuck on the base,
wherein the base of the support member is a plate-like member including an attachment surface to be opposed to the inner surface of the glass member and a pillar-part formation surface provided with a pillar part connected to the body member on an opposite side of the attachment surface,
the attachment surface is a curved surface having a curvature at least in a first direction along the attachment, surface and projecting toward an opposite side of the pillar-part formation surface,
the double-sided adhesive tape is provided with a plurality of slits including at least one first slit open toward an upper edge located on an upper side when the base is attached to the inner surface and cut downward in a direction perpendicular to an axial line about which the base is rotated when attached to the inner surface, and at least one second slit open toward a lower edge located on a lower side and cut upward in the direction perpendicular to the axial line about which the base is rotated when attached to the inner surface, and
wherein the double-sided adhesive tape is provided with guide parts at openings at the upper edge and the lower edge of the at least one first slit and the at least one second slit, each guide part having a greater width than the at least one first slit and the at least one second slit.
2. The onboard device according to claim 1 , wherein the double-sided adhesive tape has a structure in which a lower end of the at least one first slit is located below an upper end of the at least one second slit.
3. The onboard device according to claim 1 , wherein the at least one second slit comprises a plurality of second slits, and the double-sided adhesive tape is provided with the second slits more than the at least one first slit.
4. The onboard device according to claim 1 , wherein a thickness of the base is decreased as the base is separated from the pillar part in the first direction.
5. The onboard device according to claim 1 , wherein the pillar-part formation surface is an inclined surface inclined in a direction toward the attachment surface with respect to a plane surface perpendicular to an axial direction of the pillar part as the pillar-part formation surface is separated from the pillar part in the first direction.
6. The onboard device according to claim 1 , wherein, when the base is stuck on the inner surface of the glass member via the double-sided adhesive tape, adhesion between the base and the glass member is ensured due to the double-sided adhesive tape interposed therebetween in a state in which the base is pressed by a finger in a thickness direction so as to be bent in a direction in which a first radius of curvature of the inner surface of the glass member in the first direction conforms to a second radius of curvature of the attachment surface in the first direction when the first radius of curvature is different from the second radius of curvature.
7. The onboard device according to claim 1 , wherein a back edge part of the respective guide parts is located on an inner side of an outer circumferential part of the base.
8. The onboard device according to claim 1 , being a drive recorder comprising a camera unit configured to capture an image through the glass member in a state in which the support member is attached to the glass member, and a display unit configured to display the image captured by the camera unit.
9. An attachment structure for an onboard device comprising:
a body member;
a support member projecting from the body member and including a base to be attached to a concave inner surface of a glass member having a curved shape provided in a vehicle; and
a double-sided adhesive tape prepared to be stuck on the base and the inner surface so as to attach the support member to the glass member,
wherein the double-sided adhesive tape is provided with a plurality of slits including at least one first slit open toward an upper edge located on an upper side when the base is attached to the inner surface and cut downward in a direction perpendicular to an axial line about which the base is rotated when attached to the inner surface, and at least one second slit open toward a lower edge located on a lower side and cut upward in the direction perpendicular to the axial line about which the base is rotated when attached to the inner surface, and
wherein the double-sided adhesive tape is provided with guide parts at openings at the upper edge and the lower edge of the at least one first slit and the at least one second slit, each guide part having a greater width than the at least one first slit and the at least one second slit.
10. The attachment structure for the onboard device according to claim 9 , wherein the at least one second slit comprises a plurality of second slits, and the double-sided adhesive tape is provided with the second slits more than the at least one first slit.
