Abstract

Embodiments relate to a metal frame in a head-mounted display (HMD) that is structured to absorb impact and protect components of the HMD. The metal frame has a wall that is spaced away from a protection shell securing a display panel in the HMD. When the HMD is dropped or subject to external force, the wall may deform but keep the protection shell intact. Moreover, the metal frame has protruding ridges and brackets that surround outward facing cameras on the HMD. If the HMD is dropped, the protruding ridges and brackets can provide protection to the cameras.

First claim

The invention claimed is:

1. A display, comprising:
a display panel assembly configured to display images;
a display protection shell having a front end configured to attach to the display panel assembly; and
a metal frame comprising:
a front surface,
a rear surface at an opposite side of the front surface, the display panel assembly placed between the front end of the display protection shell and the rear surface, and
a wall raised from the rear surface, the wall spaced apart from and extending along at least an edge of the display protection shell to protect the display protection shell, the wall including:
a first segment extending along the edge of the display protection shell,
a second segment angled outward from the edge, and
a third segment angled inward toward the edge, the third segment in conjunction with the second segment forming a pocket that receives a corner of the display protection shell.

2. The display of claim 1 , wherein the first segment of the wall is spaced apart from and extends between at least one corner to another corner of the display protection shell.

3. The display of claim 1 , wherein at least one corner of the display protection shell is cut out in a diagonal direction, and wherein the first segment of the wall extends straight along the edge of the display protection shell and a fourth segment, connected to the first segment, is curved relative to the first segment at an angle.

4. The display of claim 1 , wherein the corner of the display protection shell has perpendicular edges.

5. The display of claim 1 , further comprising a bracket attached to a cut-out part at a corner of the metal frame, the bracket configured to surround at least a portion of a camera.

6. The display of claim 5 , wherein the cut-out part of the metal frame has a flap having a top contour that matches a bottom contour of the bracket.

7. The display of claim 5 , wherein the bracket has a circular hole at a center through which the camera captures views.

8. The display of claim 5 , further comprising another bracket attached to an edge of the metal frame, the other bracket configured to surround at least a portion of another camera.

9. The display of claim 8 , wherein the metal frame comprises a semi-cylindrical wall at the edge to receive the other camera between the semi-cylindrical wall and the other bracket.

10. The display of claim 1 , wherein the metal frame has an opening for receiving a cooling fan.

11. The display of claim 1 , wherein the metal frame is made of magnesium.

12. The display of claim 1 , wherein a portion of the display protection shell has a frustum shape.

13. A metal frame in a head-mounted display, comprising:
a front surface,
a rear surface at an opposite side of the front surface, a display panel assembly placed between a front end of a display protection shell and the rear surface, and
a wall raised from the rear surface, the wall spaced apart from and configured to extend along at least an edge of the display protection shell to protect the display protection shell, the wall including:
a first segment extending along the edge of the display protection shell,
a second segment angled outward from the edge, and
a third segment angled inward toward the edge, the third segment in conjunction with the second segment forming a pocket that receives a corner of the display protection shell.

14. The metal frame of claim 13 , wherein the first segment of the wall is spaced apart from and extends between at least one corner to another corner of the di splay protection shell.

15. The metal frame of claim 13 , wherein at least one corner of the display protection shell is cut out in a diagonal direction, and wherein the first segment of the wall extends straight along a side edge of the display protection shell and a fourth segment, connected to the first segment, is curved relative to the first segment at an angle.

16. The metal frame of claim 1 , wherein the corner of the display protection shell has perpendicular edges.

17. The metal frame of claim 13 , wherein the metal frame further comprises a flap having a top contour that matches a bottom contour of a bracket that protects a camera.

18. The metal frame of claim 17 , wherein the metal frame further comprises a semi-cylindrical wall at an edge to receive another camera between the semi-cylindrical wall and another bracket.

19. The metal frame of claim 13 , wherein the metal frame has an opening for receiving a cooling fan.

20. The metal frame of claim 13 , wherein the metal frame is made of magnesium.
