Abstract

Disclosed is an exterior case. This exterior case comprises: a base including an internal space for storing an electronic device; a circuit board disposed on a first surface of the base and including a plurality of light-emitting elements for emitting light; and a weft-and-warp-woven outer cover surrounding the base and the circuit board and transmitting emitted light, wherein at least one among the weft and the warp may be formed of a thermoplastic polyester elastomer (TPEE) coating yarn which uses a transparent TPEE as a core and includes a coating layer made of polyurethane (PU) and surrounding the core.

First claim

The invention claimed is:

1. An exterior case comprising:
a base comprising an inner space to receive an electronic device;
a circuit board disposed on a first surface of the base and comprising a plurality of light emitting elements to emit light;
an outer skin configured to cover the base and the circuit board, and woven with wefts and warps allowing the emitted light to pass therethrough; and
a plurality of light passing holes corresponding to the plurality of light emitting elements,
wherein at least one of the wefts and the warps is formed with a thermoplastic polyester elastomer (TPEE) coating thread comprising a core formed with a transparent TPEE and a coating layer formed with polyurethane (PU) and surrounding the core.

2. The exterior case of claim 1 , wherein the wefts and the warps allow light to pass therethrough and are stretched when a tension is applied thereto.

3. The exterior case of claim 1 , wherein a transparent coating is formed on a concavo-convex portion of the outer skin formed by weaving.

4. The exterior case of claim 1 , further comprising a holder configured to attach the circuit board to the base to seat the circuit board on the base.

5. The exterior case of claim 4 , wherein the holder comprises openings corresponding to the plurality of light emitting elements.

6. The exterior case of claim 1 , wherein the warps are configured in one color, and colors of respective wefts are selected based on a color of the outer skin that is visually recognized.

7. The exterior case of claim 6 , wherein the colors of the respective wefts are selected to become lighter or darker in sequence in at least an area of the outer skin.

8. The exterior case of claim 6 , wherein the colors of the respective wefts are selected to hide the circuit board.

9. The exterior case of claim 1 , wherein the circuit board comprises a communication device configured to receive a signal of the electronic device, a memory configured to store outer skin information including a color or a color density of the outer skin, and a controller operatively connected with the communication device and the memory.

10. The exterior case of claim 9 , wherein the controller is configured to select a color of respective light emitting elements based on a color or a color density of an area of the outer skin corresponding to a position of the respective light emitting elements.

11. The exterior case of claim 9 , wherein the controller is configured to indicate information through the light emitting elements based on the received signal of the electronic device.

12. The exterior case of claim 1 , further comprising a coil electrically connected with the circuit board, and configured to generate a current through electromagnetic induction with the electronic device.

13. The exterior case of claim 1 , wherein the base comprises a second surface facing the first surface, and a third surface surrounding a space between the first surface and the second surface, and
wherein the first surface is a cover that is disposed to be rotatable about one edge of the base, and opens and closes a front surface of the electronic device.

14. The exterior case of claim 13 , further comprising a cover holder configured to attach the circuit board to the first surface to seat the circuit board to the first surface.

15. The exterior case of claim 13 , wherein the circuit board is connected with a diode board comprising the light emitting elements, and a flexible printed circuit board (FPCB) to supply a signal and a power.
