Camera module for a motor vehicle and method of mounting a camera module
First Claim
1. A camera module for a motor vehicle, comprising a lens assembly, a housing having a back wall and a front end surrounding an opening, and an image sensor carried by the back wall and arranged within the housing in or close to an image plane of the lens assembly, the housing comprising a lens holder extending between the front end and the back wall, the camera module further comprising a tube which is fixed to the lens holder at the front end such that the tube surrounds the opening and extends from the opening into the housing, wherein the lens assembly is connected to a bottom end section of the tube by a connection, and wherein a thermal expansion coefficient of the tube is higher than a thermal expansion coefficient of the lens holder, the connection extending over less than half of the axial length of the lens assembly.

Abstract
A motor vehicle camera module (12) having a lens assembly (20), a housing (22) forming a front end (50) surrounding an opening (28), an image sensor (24) carried by a back wall (32) within the housing (22) adjacent an image plane (A). The housing (22) having a lens holder (53) between the front end (50) and the back wall (32). The camera module (12) has a tube (26) fixed to the lens holder (53) at the front end (50). The tube (26) surrounds the opening (28) and extends from the opening (28) into the housing (22). The lens assembly (20) is connected to a tube bottom end section by threads (71, 72). The thermal expansion coefficient of the tube (26) is higher than that of the lens holder (53). The threads (71, 72) extends over less than half of the axial length (hL) of the lens assembly (20).
