Abstract

A terminal provided with a flexible screen, the terminal including a flexible screen assembly, a first fixed frame ( 6 ), a second fixed frame ( 7 ), a sliding roll-up assembly, and a magnetic component ( 9 ); the sliding roll-up assembly includes a first roller ( 3 ) and a second roller ( 4 ); the flexible screen assembly includes a flexible screen main body ( 1 ) and a rollable supporting component ( 2 ); the flexible screen assembly is supported by the first roller ( 3 ) and the second roller ( 4 ) and includes an opposite first side and second side; the first side is fixed to a first end of the first fixed frame ( 6 ), and the second side and the second fixed frame ( 7 ) are connected by an elastic member ( 8 ); the magnetic member ( 9 ) is provided on the support ( 5 ) and magnetically cooperates with the rollable supporting component ( 2 ).

First claim

What is claimed is:

1. A terminal provided with a flexible screen, comprising:
a flexible screen assembly,
a first fixed frame,
a second fixed frame,
a sliding roll-up assembly, and
a magnetic component; wherein:
the sliding roll-up assembly comprises:
a first roller, and
a second roller;
wherein the first roller and the second roller are parallel and arranged in a first direction, the first roller and the second roller are connected by a support, the first roller is arranged on a side of the second roller facing away from the first fixed frame, and the sliding roll-up assembly performs reciprocating motion in the first direction;
the flexible screen assembly comprises:
a flexible screen main body; and
a rollable supporting component, disposed on a side facing away from a display surface of the flexible screen main body;
wherein the flexible screen assembly is arranged around the sliding roll-up assembly, and the flexible screen assembly is supported by the first roller and the second roller;
the flexible screen assembly further comprises:
a first side, fixed to a first end of the first fixed frame; and
a second side, connected to the second fixed frame by an elastic component;
wherein the first side and the second side are opposite; the first end of the first fixed frame and the second fixed frame are arranged on a same side of a plane where the support is located; the second fixed frame is arranged between the plane where the support is located and the first end of the first fixed frame; and when the flexible screen assembly is at a rolling station, the second fixed frame is between the first roller and the second roller, and an area, between the first side and the first roller, in the flexible screen assembly forms a visible area; and
the magnetic component is arranged on the support, between the first roller and the second roller, and close to the first roller; and the magnetic component magnetically cooperates with the rollable supporting component to unroll the flexible screen assembly.

2. The terminal provided with the flexible screen according to claim 1 , wherein the rollable supporting component comprises:
a plurality of rigid supporting sheets, arranged in an arrangement direction of the first side and the second side; and
soft adhesives, wrapping outer sides of the plurality of rigid supporting sheets and filled between adjacent rigid supporting sheets.

3. The terminal provided with the flexible screen according to claim 2 , wherein a surface of each rigid supporting sheet on a side facing the flexible screen main body and a surface of each rigid supporting sheet on a side facing away from the flexible screen main body are curved surfaces protruding towards the flexible screen main body; and
a curvature of the curved surfaces is same as a curvature of an outer surface of the first roller and a curvature of an outer surface of the second roller.

4. The terminal provided with the flexible screen according to claim 2 , wherein a material of the rigid supporting sheets is a rigid material, and the rigid material may magnetically cooperate with the magnetic component.

5. The terminal provided with the flexible screen according to claim 2 , wherein on a side of the soft adhesives facing away from the flexible screen main body, the soft adhesives, between two adjacent rigid supporting sheets, is provided with a groove.

6. The terminal provided with the flexible screen according to claim 5 , wherein in a direction from bottom of the groove to opening of the groove, a distance between two side faces of the grooves gradually increases.

7. The terminal provided with the flexible screen according to claim 1 , wherein the rollable supporting component and the flexible screen main body are adhesively fixed.

8. The terminal provided with the flexible screen according to claim 1 , wherein:
the first roller comprises:
a first fixed shaft, and
a first rotating component, wherein the first rotating component is sleeved on an outer side of the first fixed shaft and is rotatable around the first fixed shaft, and two ends of the first fixed shaft are fixed to the support;
the second roller comprises:
a second fixed shaft, and
a second rotating component, wherein the second rotating component is sleeved on an outer side of the second fixed shaft and is rotatable around the second fixed shaft, and two ends of the second fixed shaft are fixed to the support; and
a diameter of the first rotating component is greater than a diameter of the second rotating component.

9. The terminal provided with the flexible screen according to claim 8 , wherein a plane where the first fixed shaft and the second fixed shaft are located is parallel to the visible area.

10. The terminal provided with the flexible screen according to claim 1 , wherein the magnetic component is an electromagnet.

11. The terminal provided with the flexible screen according to claim 1 , wherein the magnetic component magnetically cooperates with the rollable supporting component during an unrolling process of the flexible screen assembly; and
the magnetic component does not work during a rolling process of the flexible screen assembly.

12. The terminal provided with the flexible screen according to claim 1 , further comprising:
a movable frame, arranged at an end of the support away from the second roller;
wherein the movable frame cooperates with the first fixed frame to form a containing space configured to contain the sliding roll-up assembly and the flexible screen assembly, and an opening of the containing space faces the visible area.

13. The terminal provided with the flexible screen according to claim 1 , wherein the second fixed frame is fixed to the first fixed frame.

14. The terminal provided with the flexible screen according to claim 1 , wherein the second fixed frame is fixed to the support.
