Camera module for vehicle vision system
First Claim
1. A method for assembling a camera module for use in a vision system for a vehicle, said method comprising:
- providing a rear housing portion, said rear housing portion comprising a first mating surface and a first perimeter flange at least partially around said first mating surface, said first perimeter flange having a first securing surface opposite said first mating surface;
providing a front housing portion, said front housing portion comprising a second mating surface and a second perimeter flange at least partially around said second mating surface, said second perimeter flange having a second securing surface opposite said second mating surface;
providing a securing element having first and second tabs that extend from a center portion of said securing element;
with said first mating surface at said second mating surface, disposing said securing element along said first and second perimeter flanges;
bending said first and second tabs to overlap and engage said first and second securing surfaces of said first and second perimeter flanges, respectively; and
crimping said securing element at said first and second perimeter flanges to urge said first mating surface against said second mating surface to secure said rear housing portion relative to said front housing portion.

Abstract
A method for assembling a vehicle vision system camera module includes providing rear and front housing portions, each having a respective mating surface and perimeter flange at least partially around the mating surface, with the perimeter flange having a securing surface opposite the first mating surface. With the mating surfaces at one another, a securing element is disposed along the perimeter flanges of the front and rear housing portions. First and second tabs of the securing element are bent to overlap and engage the respective securing surfaces of the respective perimeter flanges. The securing element is crimped at the perimeter flanges to urge the mating surfaces against one another to secure the rear housing portion relative to the front housing portion.

16. A method for assembling a camera module for use in a vision system for a vehicle, said method comprising:
-
providing a rear housing portion, said rear housing portion comprising a first mating surface and a first perimeter flange at least partially around said first mating surface, said first perimeter flange having a first securing surface opposite said first mating surface; providing a front housing portion, said front housing portion comprising a second mating surface and a second perimeter flange at least partially around said second mating surface, said second perimeter flange having a second securing surface opposite said second mating surface; providing a sealing element and disposing said sealing element at one of said first and second mating surfaces; providing a securing element having first and second tabs that extend from a center portion of said securing element; with said first mating surface at said second mating surface, disposing said securing element along said first and second perimeter flanges; bending said first and second tabs to overlap and engage said first and second securing surfaces of said first and second perimeter flanges, respectively; crimping said securing element at said first and second perimeter flanges to urge said first mating surface against said second mating surface to secure said rear housing portion relative to said front housing portion; wherein, when said securing element is disposed along said first and second perimeter flanges and crimped at said first and second perimeter flanges, said sealing element is disposed between said first and second mating surfaces when said first and second mating surfaces are mated together; and wherein, when said securing element is disposed along said first and second perimeter flanges and crimped at said first and second perimeter flanges, said center portion spans an interface where said first and second mating surfaces are mated together. - View Dependent Claims (17, 18, 19)

20. A method for assembling a camera module for use in a vision system for a vehicle, said method comprising:
-
providing a rear housing portion, said rear housing portion comprising a first mating surface and a first perimeter flange at least partially around said first mating surface, said first perimeter flange having a first securing surface opposite said first mating surface, wherein said rear housing portion comprises an electrical connector for electrically connecting circuitry of said camera module to a power source of a vehicle; providing a front housing portion, said front housing portion comprising a second mating surface and a second perimeter flange at least partially around said second mating surface, said second perimeter flange having a second securing surface opposite said second mating surface, wherein said front housing portion at least partially houses a lens assembly of said camera module; providing a securing element having first and second tabs that extend from a center portion of said securing element; with said first mating surface at said second mating surface, disposing said securing element along said first and second perimeter flanges; bending said first and second tabs to overlap and engage said first and second securing surfaces of said first and second perimeter flanges, respectively; crimping said securing element at said first and second perimeter flanges to urge said first mating surface against said second mating surface to secure said rear housing portion relative to said front housing portion; wherein, when said securing element is disposed along said first and second perimeter flanges and crimped at said first and second perimeter flanges, said center portion spans an interface where said first and second mating surfaces are mated together; and wherein, when said securing element is disposed along said first and second perimeter flanges and crimped at said first and second perimeter flanges, said first and second mating surfaces are mated together to seal said camera module.
