Abstract

An electronic device includes a flexible display and a device housing that defines a translation surface for the flexible display. A blade assembly is positioned between the flexible display and the translation surface. A rotor is positioned within a curvilinear section of the blade assembly and flexible display. A translation mechanism translates the blade assembly and flexible display between an extended position, a retracted position, and a peek position revealing an image capture device.

First claim

What is claimed is:

1. An electronic device, comprising:
a device housing defining a translation surface;
a blade assembly carrying a blade and slidably coupled to the device housing; and
a translation mechanism operable to slide the blade assembly between:
an extended position where the blade extends beyond an edge of the device housing; and
a retracted position where a major surface of the blade abuts a major surface of the device housing;
the translation mechanism causing a portion of the blade assembly positioned against a rear side of the device housing and another portion of the blade assembly positioned against a front side of the device housing to slide symmetrically across the rear side of the device housing and the front side of the device housing, respectively, in opposite directions;
the translation mechanism comprising a first rotor and a second rotor positioned at an end of the translation mechanism; and
the first rotor and the second rotor positioned within a curvilinear section of the blade assembly.

2. The electronic device of claim 1 , wherein the translation mechanism is attached to the device housing.

3. The electronic device of claim 2 , the translation mechanism comprising a first drive screw and a second drive screw.

4. The electronic device of claim 3 , wherein the first drive screw and the second drive screw are coupled together by the blade assembly.

5. The electronic device of claim 4 , further comprising a first blade mover coupled to the first drive screw and a second blade mover coupled to the second drive screw.

6. The electronic device of claim 5 , wherein actuation of the first drive screw and the second drive screw cause the first blade mover and the second blade mover to move symmetrically in opposite directions as the first drive screw and the second drive screw rotate.

7. The electronic device of claim 6 , further comprising a motor turning the first drive screw.

8. The electronic device of claim 5 , further comprising a tensioner coupled to the first blade mover.

9. The electronic device of claim 8 , the tensioner coupled between the blade assembly and the first blade mover.

10. The electronic device of claim 9 , the tensioner comprising one or more springs applying a loading force biasing an end of the blade assembly toward an end of the device housing.

11. The electronic device of claim 9 , the tensioner comprising a split tensioner with a first tensioner portion and a second tensioner portion separated by a thin bar.

12. The electronic device of claim 2 , wherein the translation mechanism comprises a rotor and the blade assembly defines a J-shape with a curved portion of the J-shape wrapped around the rotor.

13. The electronic device of claim 1 , the first rotor and the second rotor physically separated, thereby allowing mechanical and/or electronic components to be situated between the first rotor and the second rotor.

14. The electronic device of claim 1 , wherein the blade assembly is rigidly coupled to the translation mechanism.

15. The electronic device of claim 1 , further comprising a tensioner coupled to the translation mechanism.

16. The electronic device of claim 15 , wherein the tensioner is coupled between the blade assembly and the translation mechanism.

17. The electronic device of claim 1 , where a space situates between the first rotor and the second rotor.

18. An electronic device, comprising:
a device housing;
a blade assembly;
a translation mechanism causing a portion of the blade assembly positioned against a rear side of the device housing and another portion of the blade assembly positioned against a front side of the device housing to slide symmetrically across the rear side of the device housing and the front side of the device housing, respectively, in opposite directions;
a first blade mover and a second blade mover each coupled to the translation mechanism; and
a split tensioner coupled between the blade assembly and the first blade mover, with a first tensioner portion and a second tensioner portion separated by a thin bar.

19. The electronic device of claim 18 , further comprising a tensioner coupled between the blade assembly and the translation mechanism.

20. The electronic device of claim 19 , the tensioner comprising a split tensioner with a first tensioner portion and a second tensioner portion separated by a thin bar.
