Abstract

An electronic device is disclosed. According to the present disclosure, when the strap portion turns from a first state in which the handle and the strap portion are positioned adjacent to each other to a second state in which the strap portion is positioned away from the handle, the strap portion remains in the second state and, when the link button is pressed, the strap portion turns back to the first state. An electronic device according to the present disclosure may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.

First claim

What is claimed is:

1. An electronic device for interacting with content provided from an augmented reality (AR) or a virtual reality (VR) device, the electronic device comprising:
a strap portion of which both ends are coupled to a handle of the electronic device; and
a strap tension adjuster disposed inside the handle, wherein the strap tension adjuster comprises:
a link button disposed to partially protrude to an outside of the handle;
a first spring coupled with one end of the strap portion;
a first gear around which the first spring is wound and rotatable in a first direction, wherein the first gear comprises first sawteeth with first slope sides inclined in the first direction; and
a second gear coupled and fastened to the link button so as not to be rotatable, wherein the second gear comprises second sawteeth with second slope sides inclined in a second direction,
wherein the strap portion remains in a second state when the strap portion turns from a first state in which the handle and the strap portion are positioned adjacent to each other to the second state in which the strap portion is positioned away from the handle and the strap portion turns back to the first state when the link button is pressed,
wherein the first gear is spinnable in the second direction opposite to the first direction when the link button is pressed, and
wherein the first sawteeth and the second sawteeth are symmetrically positioned such that the first slope sides face the second slope sides.

2. The electronic device of claim 1 , wherein the second gear comprises a receiving groove for receiving a portion of the link button.

3. The electronic device of claim 2 , wherein the receiving groove has openings formed in both ends thereof to allow the portion of the link button to move along a straight line inside the receiving groove.

4. The electronic device of claim 3 , wherein the portion of the link button comprises a first arm.

5. The electronic device of claim 4 , wherein the first arm is longer than the receiving groove, wherein the first arm is disposed to be slidable in the receiving groove, and wherein the first arm pushes the first gear away from the second gear based on the link button being pressed.

6. The electronic device of claim 1 , wherein the first spring is a spiral spring.

7. The electronic device of claim 6 , wherein the first spring is disposed so that a central axis of the first spring is coaxial with a rotation axis of the first gear.

8. The electronic device of claim 1 , wherein the strap tension adjuster further comprises a second spring elastically supporting the first gear, and wherein the second spring is disposed so that a central axis of the second spring is coaxial with a rotation axis of the first gear.

9. The electronic device of claim 8 , wherein the second spring is positioned inside the first gear.

10. The electronic device of claim 8 , further comprising a pin supporting the first gear and the second gear to be placed in a predetermined position inside the handle, wherein the pin is disposed inside the handle so that a central axis of the pin is coaxial with the rotation axis of the first gear.

11. The electronic device of claim 10 , wherein the pin passes through the first gear and the second gear along the rotation axis of the first gear, and wherein the second spring is coupled with the pin.

12. The electronic device of claim 10 , wherein one end or both ends of the pin are fastened to an inner wall of the handle.

13. The electronic device of claim 1 , further comprising a connecting element connecting an end of the strap portion with the first spring.

14. The electronic device of claim 1 , wherein another end of the strap portion is rotatably connected to the handle.
