Abstract

A retractable virtual reality device includes a rear cover, a front cover, a first restraining component, a second restraining component, and a display module. The front cover is movably combined with the rear cover. The first restraining component is fixed on the front cover. The second restraining component is movably disposed on the rear cover and for restraining the first restraining component. The display module includes a sleeve, a lens, and a display. The sleeve is fixed on the rear cover. The lens is disposed on a side of the sleeve. The display is disposed on the front cover and movably combined with the other side of the sleeve. By cooperation of the first restraining component and the second restraining component, the display and the front cover are movable relative to the lens and the rear cover, which reduces an overall size of the virtual reality device for easy carry.

First claim

What is claimed is:

1. A retractable virtual reality device comprising:
a rear cover;
a front cover movably combined with the rear cover, the front cover being movable relative to the rear cover between a using position and a folding position along a first direction and a second direction opposite to the first direction;
a first restraining component disposed on the front cover;
a second restraining component movably disposed on the rear cover to optionally restrain the first restraining component; and
a display module comprising:
at least one lens assembly disposed on the rear cover; and
at least one display component disposed on the front cover and spaced away from the at least one lens assembly at a distance between the at least one display component and the at least one lens assembly;

wherein when the second restraining component is driven by an external force to disengage from the first restraining component, the front cover is allowed to move relative to the rear cover between the using position and the folding position to drive the at least one display component to move relative to the at least one lens assembly to adjust the distance between the at least one display component and the at least one lens assembly, and when the front cover is located at the using position or at the folding position relative to the rear cover, the second restraining component is driven to restrain the first restraining component to prevent the front cover from moving relative to the rear cover, so that the at least one display component is restrained from moving relative to the at least one lens assembly to fix the distance between the at least one display component and the at least one lens assembly.

2. The retractable virtual reality device of claim 1 , wherein the display module further comprises at least one socket component, a side of the at least one socket component is adjacent to the at least one lens assembly and installed on the rear cover together with the at least one lens assembly, and another side of the at least one socket component opposite to the side of the at least one socket component is adjacent to the at least one display component.

3. The retractable virtual reality device of claim 1 , wherein the display module further comprises at least one socket component, a side of the at least one socket component is adjacent to the at least one display component and installed on the front cover together with the at least one display component, and another side of the at least one socket component opposite to the side of the at least one socket component is adjacent to the at least one lens assembly.

4. The retractable virtual reality device of claim 1 , further comprising a first operating component disposed on the rear cover in a movable manner along a third direction perpendicular to the first direction and connected to the second restraining component, the first operating component driving the second restraining component to move along the third direction so as to disengage the second restraining component from the first restraining component when the first operating component is driven by the external force.

5. The retractable virtual reality device of claim 4 , further comprising at least one first recovering component disposed between the second restraining component and the rear cover to bias the second restraining component to recover along a fourth direction opposite to the third direction.

6. The retractable virtual reality device of claim 5 , wherein the at least one first recovering component drives the second restraining component to restrain the first restraining component when the front cover is located at the using position or the folding position relative to the rear cover.

7. The retractable virtual reality device of claim 6 , further comprising a second operating component disposed on the rear cover in a movable manner along the third direction, the second operating component pushing the second restraining component to move along the third direction to disengage the second restraining component from the first restraining component during a process that the second operating component moves relative to the rear cover along the third direction to engage with the front cover.

8. The retractable virtual reality device of claim 7 , wherein the second operating component comprises:
an operating portion exposed out of the rear cover;
an abutting portion connected to the operating portion to push the second restraining component; and
a hook portion connected to the operating portion to engage with the front cover;
wherein the operating portion drives the abutting portion to push the second restraining component to move along the third direction to disengage the second restraining component from the first restraining component during a process that the operating portion drives the hook portion to move along the third direction to engage with the front cover.

9. The retractable virtual reality device of claim 8 , wherein an engaging portion is formed on the front cover, when the front cover is located at the using position relative to the rear cover, the engaging portion is aligned with the hook portion along the third direction, so that the hook portion driven by the operating portion engages with the engaging portion, when the front cover is located at the folding position relative to the rear cover, the engaging portion is not aligned with the hook portion along the third direction, so that the hook portion driven by the operating portion is prevented from engaging with the engaging portion.

10. The retractable virtual reality device of claim 7 , further comprising a second recovering component disposed between the second operating component and the rear cover to bias the second operating component to recover along the fourth direction opposite to the third direction.

11. The retractable virtual reality device of claim 1 , further comprising at least one resilient component disposed between the front cover and the rear cover, the at least one resilient component driving the front cover to move relative to the rear cover to the using position along the first direction when the second restraining component disengages from the first restraining component.

12. The retractable virtual reality device of claim 11 , further comprising at least one positioning column, an end of the at least one positioning column passing through the first restraining component to be fixed onto the front cover, another end of the at least one positioning column being movably connected to the rear cover, the at least one resilient component being sheathed on the at least one positioning column, and two ends of the at least one resilient component abutting against the first restraining component and the rear cover respectively.

13. The retractable virtual reality device of claim 12 , wherein a sectional area of the at least one positioning column gradually increases along the second direction.

14. The retractable virtual reality device of claim 1 , wherein the display module comprises two socket components parallel to each other, two lens assemblies parallel to each other, and two display components parallel to each other.
