Vehicle-mounted camera
[SUMMARY] [OBJECT] To provide a vehicle-mounted camera capable of achieving both of miniaturization and high functionality. [MEANS FOR SOLVING] The vehicle-mounted camera includes an optical unit, a frame, a cover member, a holder, and a pair of screw members. The frame includes a front wall portion having a flat plate shape and extending along a plane orthogonal to an axis, and a pair of first through-hole portions provided to the front wall portion. The cover member includes a pair of second through-hole portions adjacent to the pair of first through-hole portions in a forward direction of the axis. The holder includes a holding portion that holds the optical unit, a pair of columnar portions that protrude in the forward direction and are inserted into the pair of first through-hole portions and the pair of second through-hole portions from a rearward direction of the axis, and a pair of screw hole portions formed toward the rearward direction from distal end portions of the pair of columnar portions. The pair of screw members fix the holder and the cover member to the frame by being inserted into the pair of second through-hole portions from the forward direction and fastened to the pair of screw hole portions.
1. A vehicle-mounted camera, comprising:
an optical unit including a lens;
a frame including
a front wall portion having a flat plate shape and extending along a plane orthogonal to an axis, and
a pair of first through-hole portions provided to the front wall portion;
a cover member including a pair of second through-hole portions adjacent to the pair of first through-hole portions in a forward direction of the axis;
a holder including
a holding portion that holds the optical unit,
a pair of columnar portions that protrude in the forward direction and are inserted into the pair of first through-hole portions and the pair of second through-hole portions from a rearward direction of the axis, and
a pair of screw hole portions formed toward the rearward direction from distal end portions of the pair of columnar portions; and
a pair of screw members that fix the holder and the cover member to the frame by being inserted into the pair of second through-hole portions from the forward direction and fastened to the pair of screw hole portions,
wherein the pair of screw hole portions do not penetrate through the holder in the rearward direction.
2. The vehicle-mounted camera according to claim 1 , further comprising
an imaging device board disposed on a back surface of the holder, the back surface facing in the rearward direction.
3. The vehicle-mounted camera according to claim 2 , wherein
the imaging device board faces at least one of the pair of screw hole portions in the rearward direction.
4. The vehicle-mounted camera according to claim 1 , wherein
the optical unit has an optical axis inclined with respect to the axis.
5. The vehicle-mounted camera according to claim 4 , wherein
the holder further includes a regulating surface inclined with respect to a plane orthogonal to the optical axis and regulated by a back surface of the front wall portion, the back surface facing in the rearward direction.
6. The vehicle-mounted camera according to claim 5 , wherein
the regulating surface includes a pair of regulating surfaces respectively extending around rear end portions of the pair of columnar portions.
7. The vehicle-mounted camera according to claim 1 , wherein
the cover member further includes a pair of boss portions that protrude in the direction of the axis and include the pair of second through-hole portions.
8. The vehicle-mounted camera according to claim 1 , wherein
the cover member is a resin molded product.
9. The vehicle-mounted camera according to claim 1 , wherein
the frame is a sheet metal processed product.
10. The vehicle-mounted camera according to claim 1 , wherein
the holder is a die-cast product.
