Abstract

A bonding structure for fixing a plate member inside a housing storing the plate member includes an opening, a fixing portion, adhesive, and a transmissive portion. The opening connects a first space surrounded by the housing and a first surface of the plate member facing the housing with a second space located by a second surface of the plate member opposite the first surface. The fixing portion faces the first surface, is positioned in accordance with the opening, and includes an ultraviolet transmissive material. The adhesive is ultraviolet curing adhesive located at the opening and fixing the fixing portion and the plate member to each other. The transmissive portion is located at the periphery of a side surface of the plate member and transmits ultraviolet light.

First claim

The invention claimed is:

1. A bonding structure for fixing a plate member inside a housing storing the plate member, the bonding structure comprising:
an opening connecting a first space, surrounded by the housing and a first surface of the plate member facing the housing, with a second space located by a second surface of the plate member opposite the first surface;
a fixing portion facing the first surface, positioned in accordance with the opening, and including an ultraviolet transmissive material;
an ultraviolet curing adhesive located at the opening and fixing the fixing portion and the plate member to each other; and
a transmissive portion located at a periphery of a side surface of the plate member and transmitting ultraviolet light.

2. The bonding structure of claim 1 , further comprising a light guide including the ultraviolet transmissive material and arranged in the first space to be spatially continuous from the transmissive portion to the fixing portion.

3. The bonding structure of claim 2 , wherein the light guide is spatially continuous from the second space to the fixing portion.

4. The bonding structure of claim 1 , wherein the opening is one or both of a through-hole passing through the plate member and a notched recess provided in a portion of an outer edge of the plate member.

5. The bonding structure of claim 4 , further comprising a light guide including the ultraviolet transmissive material and arranged in the first space to be spatially continuous from the transmissive portion to the fixing portion,
wherein the light guide is partially positioned in the notched recess.

6. The bonding structure of claim 1 , further comprising a reflector arranged in the first space to reflect the ultraviolet light incident from the opening towards a bonding portion between the fixing portion and the plate member.

7. The bonding structure of 1 ,
wherein the fixing portion comprises a hole from a section of the fixing portion facing the plate member towards the housing; and
wherein the ultraviolet curing adhesive is located in the hole.

8. An imaging apparatus comprising:
a substrate;
an imaging optical system;
an image sensor mounted on the substrate;
a housing storing the substrate, the image sensor, and the imaging optical system; and
a bonded structure fixing the substrate in the housing;
wherein the bonded structure comprises:
an opening connecting a first space, surrounded by the housing and a first surface of the substrate facing the housing, with a second space located by a second surface of the substrate opposite the first surface;
a fixing portion facing the first surface, positioned in accordance with the opening, and including an ultraviolet transmissive material;
an ultraviolet curing adhesive located at the opening and fixing the fixing portion and the substrate to each other; and
a transmissive portion located at a periphery of a side surface of the substrate and transmitting ultraviolet light.

9. An on-vehicle camera comprising:
an imaging apparatus;
wherein the imaging apparatus comprises:
a substrate;
an imaging optical system;
an image sensor mounted on the substrate;
a housing storing the substrate, the image sensor, and the imaging optical system; and
a bonded structure fixing the substrate in the housing;

wherein the bonded structure comprises:
an opening connecting a first space, surrounded by the housing and a first surface of the substrate facing the housing, with a second space located by a second surface of the substrate opposite the first surface;
a fixing portion facing the first surface, positioned in accordance with the opening, and including an ultraviolet transmissive material;
an ultraviolet curing adhesive located at the opening and fixing the fixing portion and the substrate to each other; and
a transmissive portion located at a periphery of a side surface of the substrate and transmitting ultraviolet light.
