Abstract

An optical mount includes a frame adapted to support display optical systems and heat emitting electronic components. The mount includes a first portion housing the electronic components and one or more support components extending away from the electronic components. The one or more support components may include temple arms adapted to support the frame on the head of a wearer of the optical mount. The frame may be comprised of a thermally conductive material coupled to the electronic components. The support components include a first side and a second side, and at least one void positioned between the first side and the second side adapted to convey heat away from the electronic components. The void may define a bifurcated region in the support component.

First claim

What is claimed is:

1. An apparatus, comprising;
a frame comprising a front portion and side arms, an individual side arm defining a void extending from a top surface of the individual side arm through an entirety of the individual side arm to a bottom surface of the individual side arm, the void enclosed by interior side walls and open at the top surface of the individual side arm;
a display optical system mounted on the front portion of the frame;
a heat emitting electronic component mounted on the front portion of the frame; and
a thermally conductive element coupled to the heat emitting electronic component and extending along an outside surface of the individual side arm on a far side of the void relative to an inside surface of the individual side arm, the thermally conductive element configured to conduct heat away from the electronic component and toward the outside surface of the individual side arm on the far side of the void, the void configured to provide convective cooling of some of the heat as air passes into the void at the bottom surface and out at the top surface.

2. The apparatus of claim 1 , wherein the frame comprises a second individual side arm that defines a second void that is configured to provide convective cooling of the second individual side arm.

3. The apparatus of claim 2 , further comprising a second thermally conductive element coupled to the heat emitting electronic component and extending along a second outside surface of the second individual side arm.

4. The apparatus of claim 1 , wherein the interior side walls of the void are joined by an arch-shaped end wall.

5. The apparatus of claim 4 , wherein the arch-shaped end wall is configured to add structural strength to the individual side arm.

6. The apparatus of claim 4 , wherein the interior side walls of the void are joined by another arch-shaped end wall at an opposite end of the void from the arch-shaped end wall.

7. The apparatus of claim 1 , wherein the individual side arm is formed from a thermally conductive material.

8. The apparatus of claim 1 , wherein the thermally conductive element comprises at least one layer of graphite.

9. A head mounted display, comprising:
a housing including a display optical system and a heat producing electronic component;
a temple arm extending away from the housing and adapted to support the head mounted display on an ear of a wearer, the temple arm defining a void enclosed by interior side walls and open at top and bottom surfaces of the temple arm; and
a thermally conductive element extending from the heat producing electronic component to an exterior surface of the temple arm proximate to the void.

10. The head mounted display of claim 9 , wherein the thermally conductive element comprises carbon nanoparticles.

11. The head mounted display of claim 9 , wherein the thermally conductive element comprises a graphite layer.

12. The head mounted display of claim 9 , wherein the temple arm comprises a nanocarbon infused material configured to conduct heat.

13. The head mounted display of claim 12 , wherein the void is configured to provide convective cooling of some of the heat as air passes into the void at the bottom surface and out at the top surface.

14. A head mounted display apparatus, comprising:
a housing including a heat producing electrical component and a display optical system; and
a first temple arm extending away from the housing, the first temple arm defining a void enclosed by interior side walls and open at top and bottom surfaces of the first temple arm.

15. The head mounted display apparatus of claim 14 , further comprising a second temple arm extending away from the housing and defining a second void open at top and bottom surfaces of the second temple arm.

16. The head mounted display apparatus of claim 14 , wherein the interior side walls include a first interior side wall and a second interior side wall joined by a first arcuate wall and a second arcuate wall.

17. The head mounted display apparatus of claim 14 , wherein a length of the void measured in-line with a long axis of the first temple arm is longer than a height of the void measured between the top and bottom surfaces.

18. The head mounted display apparatus of claim 17 , wherein the length of the void measured along the long axis is less than half of a length of the first temple arm.

19. The head mounted display apparatus of claim 14 , wherein, relative to a long axis of the first temple arm, the void is positioned in a half of the first temple arm proximate to the housing.

20. The head mounted display apparatus of claim 14 , wherein at least one of the interior side walls of the void has a curved shape.
