First Claim
1. A vehicle vision system comprising:
- a camera module configured to attach at an in-cabin surface of a windshield of a vehicle equipped with said vision system;
wherein said camera module comprises a housing and an imager assembly;
wherein said imager assembly comprises a structure and an imager and a lens, and wherein said imager is disposed at an imager circuit board of said imager assembly;
a thermal element configured to attach at said structure of said imager assembly, wherein said thermal element comprises a support element and a thermal pad disposed at least partially along said support element;
wherein, with said thermal element attached at said structure of said imager assembly, a first portion of said thermal pad is engaged with and in thermal conductivity with said imager circuit board, and wherein, with said imager assembly disposed at said housing of said camera module, a second portion of said thermal pad is engaged with and in thermal conductivity with said housing;
wherein said thermal element comprises a clip portion that clips onto said structure of said imager assembly to engage said first portion of said thermal pad with said imager circuit board; and
wherein said clip portion is configured so that said second portion of said thermal pad is angled relative to said first portion of said thermal pad, and wherein, with said clip portion clipped onto said structure of said imager assembly and with said imager assembly disposed at said housing of said camera module, said first portion of said thermal pad extends partially along and is pressed into engagement with said imager circuit board and said second portion of said thermal pad extends partially along and is pressed into engagement with said housing.

Abstract
A vehicle vision system includes a camera module configured to attach at an in-cabin surface of a windshield of a vehicle equipped with the vision system. The camera module includes a housing and an imager assembly. The imager assembly includes a structure and an imager and a lens. The imager is disposed at an imager circuit board of the imager assembly. A thermal element is configured to attach at the structure of the imager assembly and includes a support element and a thermal pad disposed at least partially along the support element. With the thermal element attached at the structure of the imager assembly, a first portion of the thermal pad is engaged with the imager circuit board, and wherein, with the imager assembly disposed at the housing of the camera module, a second portion of the thermal pad is engaged with the housing.
