Camera with curled lid and spring element for PCB positioning
First Claim
1. A camera for a vision system for a vehicle, said camera comprising:
- a housing comprising a front housing portion and a rear housing portion;
wherein said front housing portion includes a lens barrel having a lens assembly;
wherein said rear housing portion includes a connector portion configured to connect to a wire harness of a vehicle when said camera is disposed at the vehicle;
wherein said front and rear housing portions are mated together to establish an inner cavity in said housing;
an imager circuit board disposed in said inner cavity in said housing, and wherein an imager is disposed at said imager circuit board and optically aligned with said lens assembly;
wherein, when said front and rear housing portions are mated together, perimeter flanges of said front and rear housing portions are curled and folded relative to each other to seal said front housing portion relative to said rear housing portion; and
wherein, when said camera is disposed at a vehicle, said camera captures image data for use in a vision system of the vehicle.

Abstract
A camera for a vehicle vision system includes a housing having a front housing portion with a lens barrel and lens assembly, and a rear housing portion with a connector. The front and rear housing portions are mated together to establish an inner cavity in the housing. An imager circuit board is disposed in the inner cavity of the housing, with an imager disposed at the imager circuit board and optically aligned with the lens assembly. When the front and rear housing portions are mated together, perimeter flanges of the front and rear housing portions may be curled to have multiple folds to seal the front housing portion relative to the rear housing portion. The imager circuit board may be held in the inner cavity by a spring element that urges the imager circuit board in a direction toward the lens assembly.

12. A method of assembling a camera for a vehicle, said method comprising:
-
providing a camera housing having a front housing portion and a rear housing portion; wherein the front housing portion comprises a lens barrel, a lens assembly and a first perimeter flange circumscribing an opening at a rear portion of the front housing portion; wherein the rear housing portion comprises a second perimeter flange circumscribing a lid portion of said rear housing portion; disposing at least one circuit element in the front housing portion, wherein the at least one circuit element comprises an imager; aligning the imager with the lens assembly; mating the rear housing portion with the front housing portion to encase the at least one circuit element in the camera housing; wherein, when the rear housing portion is mated with the front housing portion, a connector portion is electrically connected to circuitry of the at least one circuit element, and wherein the connector portion protrudes from the lid portion of the rear housing portion and is configured for electrical connection to a wire harness of a vehicle; wherein, when the rear housing portion is mated with the front housing portion, the first and second perimeter flanges are parallel to one another and parallel to a longitudinal axis of the camera housing and lens assembly; folding the second perimeter flange over an end of the first perimeter flange such that the end of the first perimeter flange is received in a J-shaped portion of the second perimeter flange; and folding the first and second perimeter flanges together such that the end of the second perimeter flange is received in a J-shaped portion of the first perimeter flange. - View Dependent Claims (13, 14, 15)
