Abstract: A vehicular camera module includes a lens barrel having a plurality of optical elements accommodated therein, a front camera housing portion, and a rear camera housing portion mated with the front camera housing to form a housing that encases an imager printed circuit board and a processor printed circuit board. A heat transfer element is disposed between and in thermal conductive contact with the imager printed circuit board and a rear wall of the rear camera housing. The heat transfer element extends through an aperture of the processor printed circuit board. Circuitry of the camera module is electrically connected to electrical connecting elements that electrically connect to a wire harness of a vehicle when the camera module is disposed at the vehicle. Heat generated by operation of the vehicular camera module is drawn from the imager printed circuit board to the rear camera housing portion via the heat transfer element.

Abstract: A vehicular camera includes an imager printed circuit board and a lens having a plurality of optical elements. The lens is held in optical alignment with an imager at the imager printed circuit board via a dual cure one-part, filled adhesive that in its uncured state has an epoxy resin. The adhesive is both UV-curable and thermal-curable. A flexible electrical ribbon cable electrically connects circuitry of the imager printed circuit board with additional circuitry of the vehicular camera. Image data captured by the imager is provided to the additional circuitry of the vehicular camera via the flexible electrical ribbon cable. The additional circuitry includes at least a processor for processing image data captured by the imager and provided to the additional circuitry via the flexible electrical ribbon cable. The vehicular camera, when installed and used in a vehicle, captures image data for use by a vision system of the vehicle.

Abstract: A vehicular camera includes a front camera housing and a lens assembly having cylindrical barrel portion that is at least partially received at the front camera housing. An adhesive is disposed in an uncured state at the front camera housing and/or at the printed circuit board and laterally outboard of the imager. With the adhesive in the uncured state, an air gap exists between the inner surface of the lens and the imager. The adhesive is initially cured from the uncured state to an initially-cured state in an initial radiation curing process that comprises exposure to UV light for a first time period. With the adhesive in the initially-cured state, the front camera housing, with the printed circuit board adhesively attached thereto, is further cured to a further more cured state in a secondary curing process undertaken for a longer time period than the first time period.

Abstract: A camera for a vehicular vision system includes a circuit board having a first side and a second side opposite the first side. The circuit board has a first coefficient of thermal expansion (CTE). An imager is disposed at the first side of the circuit board, and a lens assembly is optically aligned with the imager. A bend-countering element is disposed at the first side or the second side of the circuit board. The bend-countering element has a second CTE that is different from the first CTE of the circuit board. The bend-countering element counters temperature-induced bending of the circuit board. With the camera disposed at the vehicle, temperature-induced bending of the bend-countering element is in an opposite direction from temperature-induced bending of the circuit board.

Abstract: A method of assembling a vehicular camera includes providing a metallic front housing member, a metallic rear housing member, a lens assembly and a circuit board. The front housing member has a lens receiving portion and a circuit board attachment portion. An imager is disposed on a first side of the circuit board and a connector is disposed on a second side of the circuit board. With the circuit board attached at the front housing member and with the lens assembly disposed at a lens receiving portion of the front housing member, images are focused at an imaging plane of the imager by adjusting the lens assembly relative to the imager. With the images focused at the imaging plane of the imager, the lens assembly is retained relative to the front housing member via an ultra-violet (UV) curable adhesive. The front housing member and the rear housing member are attached.

Abstract: A vehicular camera for a vehicular vision system includes a PCB having an imager disposed thereat, a lens barrel accommodating a lens, and a lens barrel support structure that protrudes from the PCB and at least partially circumscribes the imager. The lens barrel has an outer surface that extends between the ends of the lens barrel. The outer surface of the lens barrel is adhesively bonded to an inner surface of the lens barrel support structure via adhesive. The outer surface of the lens barrel radially opposes the inner surface of the lens barrel support structure where the adhesive is disposed. With the adhesive in its uncured state and contacting the opposed surfaces, the imager is optically aligned with the lens accommodated at the lens barrel. With the imager optically aligned with the lens, the adhesive is cured to adhesively attach the lens barrel at the lens barrel support structure.

Abstract: A method of providing a camera sub-assembly for a vehicular camera includes providing a lens barrel, a lens holder and a printed circuit board, and dispensing an adhesive in an uncured state at one or both of (i) an annular attaching surface at an outer end of a receiving structure of the lens holder and (ii) an annular attaching surface of an annular flange of the lens barrel. With the adhesive contacting both of the annular attaching surfaces, the lens optics are aligned with respect to the imaging array at the printed circuit board by utilizing a multi-axis positioning device. After aligning the lens optics with respect to the imaging array, the adhesive is cured to a first cure level and the lens barrel and the lens holder joined together by the adhesive are moved to a further curing station, where the adhesive is further cured to a second cure level.

Abstract: A vehicular camera includes a lens accommodated in a lens barrel, a lens holder that accommodates at least part of the lens holder, and a printed circuit board with an imager disposed thereat. The camera utilizes an adhesive to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially curable to an initially-cured state in an initial curing process for an initial-cure time period. The initially-cured adhesive is further curable to a further-cured state in a secondary curing process for a further-cure time period that is longer than the initial-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the vehicular camera in a vehicle.
