Overmolded temple with thermal management window
An electronic eyewear device having temples that are lightweight, aesthetically pleasant, and include thermal management. The temples each have a thermally conductive stiffener with a non-thermally conductive overmolded material forming a window. The window in each temple exposes interior components, such the stiffener to ambient air, and allows heat generated by electronic components to be released to ambient air to cool the components through convection. The windows also allow the stiffeners to be coupled to tooling and are easily overmolded. The windows provide both an aesthetic feature and a functional feature.
1 . An electronic eyewear device, comprising:
a frame configured to be worn on a head of a user;
an optical component supported by the frame; and
a temple coupled to the frame, wherein the temple comprises:
a thermally conductive support member having a proximal end that extends to a distal end;
a material overmolded on the support member and defining a window exposing a portion of the support member between the proximal end and the distal end to ambient, and
an electronic component configured to generate heat during powered operation, wherein the exposed portion of the support member is coupled to the electronic component and is configured to release the heat to ambient.
2 . The electronic eyewear device of claim 1 , wherein the window is elongated and extends along a middle portion of the temple.
3 . The electronic eyewear device of claim 1 , wherein the temple has an outside portion configured to face away from the user when worn, wherein the window is defined on the outside portion.
4 . The electronic eyewear device of claim 1 , wherein the support member is planar.
5 . The electronic eyewear device of claim 1 , wherein the material is non-thermally conductive.
6 . The electronic eyewear device of claim 5 , wherein the material is resilient.

9 . A method of making an electronic eyewear product comprising a frame configured to be worn on a head of a user, an optical component supported by the frame, a temple coupled to the frame, and an electronic component configured to generate heat during powered operation the method comprising:
forming a thermally conductive support member having a proximal end that extends to a distal end;
overmolding a material on the support member to form the temple, the overmolding producing a window within the material exposing a portion of the support member between the proximal end and the distal end to ambient, wherein the exposed portion of the support member is coupled to the electronic component and is configured to release the heat to ambient; and
coupling the temple to the frame.
10 . The method of claim 9 , wherein the window is elongated and extends along a middle portion of the temple.
11 . The method of claim 9 , wherein the temple has an outside portion configured to face away from the user when worn, wherein the window is defined on the outside portion.
12 . The method of claim 9 , wherein the support member is planar.
13 . The method of claim 9 , wherein the material is non-thermally conductive.
14 . The method of claim 13 , wherein the material is resilient.
15 . The method of claim 14 , wherein the material comprises silicon rubber.
16 . An electronic eyewear device, comprising:
a frame configured to be worn on a head of a user;
an optical component supported by the frame; and
a temple coupled to the frame, wherein the temple comprises:
support means that is thermally conductive and having a proximal end that extends to a distal end; and
means overmolded on the support means and defining a window exposing a portion of the support means between the proximal end and the distal end to ambient, and
an electronic component configured to generate heat during powered operation, wherein the exposed portion of the support means is coupled to the electronic component and configured to release the heat to ambient.
