Abstract

A wearable device may include: a strap including a substantially polygonal opening and a buckle formed at one end thereof; a buckle part configured to fasten opposite ends of the strap to each other by binding the opposite ends of the strap; and a body configured to be coupled to the opening by being fitted into the opening or decoupled from the opening. The body may include a front surface and a rear surface, and a display having a substantially polygonal shape when viewed from the top on the front surface, and a biometric sensor disposed on the rear surface.

Claims

1. A wearable device comprising:

a strap having a first end and a second end, the strap comprising a substantially polygonal opening and a buckle formed at one of the first and second ends;

a buckle part configured to fasten the first and second ends of the strap to each other by binding the first and second ends; and

a body configured to be removably coupled to the opening by being fitted into the opening,

wherein the body comprises a front surface and a rear surface, and

wherein the body comprises a display on its front surface, the display appearing to have substantially polygonal shape in a top view thereof, and wherein the body further comprises a biometric sensor disposed on its rear surface.

2. The wearable device of claim 1, wherein the substantially polygonal shape of the display is substantially rectangular, and wherein the display is curved.

3. The wearable device of claim 1, wherein the strap comprises a seating part from which the body is removable, and the seating part being formed along a circumference of the opening, and wherein the seating part comprises at least one linear portion, and

wherein the body comprises a seating recess with which the seating part of the strap is configured to be mated.

4. The wearable device of claim 3, wherein the opening is opened in a vertical direction and has a rectangular shape having a thickness, and the body is removed from the opening by elastically deforming of the seating part of the strap.

5. The wearable device of claim 3, wherein the body comprises a curved body housing, and

wherein a front surface and a rear surface of the curved body housing have a first curvature and a second curvature, respectively, the first curvature being smaller than the second curvature.

6. The wearable device of claim 5, further comprising a biometric sensor,

wherein the display is curved and has a same curvature as the first curvature, and is mounted on the front surface of the curved body housing, and

wherein the rear surface of the curved body housing comprises a planar surface on a center area of the body and the biometric sensor is disposed on the planar surface.

7. The wearable device of claim 5, wherein the curved body housing has a horizontal direction width gradually reduced from a center toward the front surface, such that the body is decoupled by moving the body out from the opening by moving the body in a first removal direction and remains coupled when the body is moved in a direction opposite the first removal direction.

8. The wearable device of claim 5, further comprising a removal structure for selectively coupling and decoupling the curved body housing with respect to the opening by moving the curved body with respect to the opening along a second removal direction.

9. The wearable device of claim 8, wherein the removal structure comprises:

a seating recess extending along a circumference of a side surface of the curved body housing and having a curvature corresponding to a curvature of the opening; and

a seating part coupled to the seating recess to fix the curved body housing to the opening.

10. The wearable device of claim 9, wherein the curvature of corresponds to a curvature of an outer side surface of the curved body housing.

11. The wearable device of claim 9, wherein the seating recess comprises a first close contact surface which comprises a first top surface, a first intermediate surface, and a first bottom surface, and has a horizontal width of an exterior corresponding to the first bottom surface that is wider than a horizontal width of an exterior corresponding to the first top surface, and

wherein the seating part comprises a second close contact surface which is in close contact with the first close contact surface and comprises a second top surface, a second intermediate surface, and a second bottom surface, and has a horizontal width of an exterior corresponding to the second bottom surface that is wider than a horizontal width of an exterior corresponding to the second top surface, thereby providing the second removal direction.

12. The wearable device of claim 11, wherein at least one of the first and second bottom surfaces are one of horizontally planar surfaces and gently inclined surfaces.

13. The wearable device of claim 5, wherein at least one of the ends of the strap is configured to have a curvature that is different than the first curvature in a boundary area where the curved body housing and the strap are coupled to each other so that the wearable device responds to a wrist curvature of a human body.

14. A wearable device comprising:

a body housing;

a curved display disposed on a front surface of the body housing;

a curved battery layered under the curved display; and

a curved body comprising at least one substrate arranged between the curved battery and a rear surface of the body housing.

15. The wearable device of claim 14, wherein the curved display and the rear surface of the body housing have a first curvature and a second curvature, respectively, and the first curvature is smaller than the second curvature so that the curved body becomes gradually thinner from a center area toward a side area in a lengthwise direction.

16. The wearable device of claim 15, wherein the battery is configured to have a curvature that is equal to that of the curved display, and is disposed on a center area under the curved display to face the curved display.

17. The wearable device of claim 14, wherein the at least one substrate comprises:

at least one rigid substrate placed horizontally or slantingly; and

at least one flexible substrate connected with the at least one rigid substrate, and the substrates form a segmental structure, and

wherein the at least one substrate includes a first substrate that is disposed on a center area between the rear surface of the body housing and a rear surface of the battery, and

wherein a first sensor is disposed on a bottom surface of the first substrate, and the first sensor has a sensor interface exposed from the center area of the rear surface of the body housing.

18. The wearable device of claim 17, wherein the rear surface of the body housing further comprises a protrusion that encloses a circumference of the sensor interface.

19. The wearable device of claim 14, wherein the curved display comprises:

a flexible display having a first curvature; and

a rigid or flexible layer integrally formed on the flexible display with a same curvature.

20. The wearable device of claim 14, further comprising a conductive piece disposed on a center area of the rear surface of the battery to stop an increase in a volume of the battery.
