Abstract

A wearable device comprises: a U-shaped bent frame; a flexible part which is located at one end of the frame and of which the shape, bent and deformed by means of external force, is fixed; a main body housing connected to an end of the flexible part; a projector which is mounted on the main body and emits light corresponding to image information; and a transparent screen which is coupled to the main body housing and reflects the light emitted from the projector to supply and image to the wearer's eyes. The wearable device can be deformed to fit the user's head so that the wearing comfort is improved, and the wearable device can be worn even when the user is wearing glasses by detaching the main body housing.

First claim

What is claimed is:

1. A wearable device comprising:
a U-shaped frame;
a flexible part coupled to one end of the frame and of which the shape is bendable and deformable by an external force;
a main body housing connected to one end of the flexible part;
a projector mounted in the main body housing and configured to project corresponding light to image information; and
a transparent screen coupled to the main body housing and configured to provide an image to wearer's eyes by reflecting the light projected from the projector,
wherein the main body housing comprises,
a first body;
a second body having the transparent screen coupled thereto; and
a hinge arranged between the first body and the second body.

2. The wearable device of claim 1 , wherein the flexible part comprises a flexible tube which is bendable while forming a curve, and
the main body housing is rotatably coupled to the flexible tube along a longitudinal direction of the flexible tube.

3. The wearable device of claim 2 , further comprising:
a shaft inserted in the flexible tube;
a rotary bracket rotatably coupled to the shaft with respect to a longitudinal direction of the flexible tube and having the main body housing secured thereto; and
a plate spring configured to locate the rotary bracket in close contact with the shaft when the rotary bracket is not rotated.

4. The wearable device of claim 2 , wherein the flexible part further comprises,
a flexible housing which covers an outer surface of the flexible tube and forms a continuous surface with the main body housing.

5. The wearable device of claim 1 , wherein the hinge is rotatable in a range of angles from 0° to 140° which are formed by the first body and the second body.

6. The wearable device of claim 1 , further comprising:
an auxiliary cable having one end coupled to the first body and the other end coupled to the third body to connect the first body and the third body with each other.

7. The wearable device of claim 6 , wherein one end of the auxiliary cable further comprises a hook configured to hook the auxiliary cable to the wearer's pair of glasses.

8. The wearable device of claim 6 , wherein the other end of the auxiliary cable further comprises a sub-battery.

9. The wearable device of claim 1 , wherein the length of the frame is adjustable.

10. The wearable device of claim 1 , further comprising:
a rubber band having one end and the other end coupled to the frame, spaced apart from each other, and located in the U-shape of the frame.

11. The wearable device of claim 10 , wherein when the wearer is wearing the wearable device, a first point located in one end of the frame, a second point located in the other end of the frame and a third point located in a middle area of the frame or the rubber band are secured to the head.

12. The wearable device of claim 1 , wherein an edge portion of the frame is bent in Z-axis from the U-shaped plane of the frame.

13. The wearable device of claim 1 , further comprising:
a battery housing located in the other end of the frame and in which a battery is mounted; and
a battery cable configured to electrically connect the battery housing and the main body housing with each other and penetrates the inside of the frame.
