Abstract

According to an embodiment of the disclosure, an electronic device may include: a housing, a sliding plate configured to slide-out from the housing, a flexible display including a first section coupled to overlap the sliding plate, and a bendable section extending from the first section and configured to be pulled out from an inner space of the housing during the slide-out, a support sheet disposed on a rear surface of the flexible display, a first curved portion located inside the housing to correspond to the bendable section, a belt connecting the support sheet and the sliding plate to each other, and a second curved portion located inside the housing to correspond to the belt and spaced apart from the first curved portion in a slide-out direction.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a sliding plate disposed to be movable with respect to the housing;
a flexible display including a first section coupled to overlap the sliding plate, and a first bendable section extending from the first section and configured to be at least partially bent when the sliding plate moves;
a multi-bar structure, at least a portion of the multi-bar structure being configured to support the first bendable section of the flexible display;
a support sheet including a second section disposed on a rear surface of the first section of the flexible display, a second bendable section disposed on a rear surface of the first bendable section of the flexible display, and a third section disposed not to overlap the flexible display, wherein the second bendable section of the support sheet is located between the multi-bar structure and the first bendable section of the flexible display;
at least one fastening part disposed in the third section;
at least one belt connecting the at least one fastening part and the sliding plate to each other;
a first curved member located, in contact with the multi-bar structure, inside the housing; and
a second curved member located, in contact with the at least one belt, inside the housing and spaced apart from the first curved member in a direction in which the sliding plate moves with respect to the housing,
wherein a connection position on the at least one belt is adjustable when the at least one belt is connected between the at least one fastening part and the sliding plate, and
wherein the support sheet includes a lattice structure including a plurality of openings.

2. The electronic device of claim 1 , wherein one or both of the first curved member and the second curved member includes a pulley.

3. The electronic device of claim 1 , wherein the lattice structure of the support sheet is provided in correspondence with the first bendable section of the flexible display.

4. The electronic device of claim 3 ,
wherein the second section and the third section are arranged with the lattice structure interposed therebetween,
wherein the second section is connected to the sliding plate, and
wherein the third section is connected to the belt.

5. The electronic device of claim 4 , further comprising:
at least one reinforcing sheet attached to the support sheet and connecting the second section and the third section across the lattice structure.

6. The electronic device of claim 5 , wherein the at least one reinforcing sheet includes stainless steel.

7. The electronic device of claim 4 , wherein the lattice structure includes at least one first area and at least one second area, the at least one first area and the at least one second area extending across the second section and the third section, the at least one second area including fewer openings than the at least one first area.

8. The electronic device of claim 4 , wherein at least one area extending across the second section and the third section includes no lattice structure.

9. The electronic device of claim 1 , wherein the support sheet includes stainless steel.

10. The electronic device of claim 1 , wherein the support sheet includes engineering plastic.

11. The electronic device of claim 1 , wherein the at least one belt includes a plurality of holes, and
wherein a tension of the at least one belt is adjusted according to a position, corresponding to the connection position, of a hole to be fastened to the at least one fastening part among the plurality of holes.

12. The electronic device of claim 11 , wherein the at least one fastening part includes a hook configured to be fastened to the plurality of holes,
wherein the tension depends on a position at which the hook is fastened to the plurality of holes.

13. The electronic device of claim 1 , further comprising:
an elastic structure comprising an elastic material disposed between the housing and the sliding plate and configured to provide a force for moving the sliding plate.
