Flexible display module and flexible display device

1. A flexible display module, comprising:

a housing, including side walls and a housing bottom, wherein the housing bottom is formed with an opening in a display area, the side walls and the housing bottom form an accommodating cavity, and a sliding groove is defined by the side walls;

a cover plate, matching the opening of the housing bottom;

rolling components, disposed in the accommodating cavity, and fixedly connected to two opposite ones of the side walls;

a flexible display panel, including a first bending area, a second bending area, and the display area, wherein the first bending area and the second bending area are arranged around the rolling components, so that the flexible display panel slides in the accommodating cavity, and a gap is formed between the flexible display panel and the cover plate to provide the flexible display panel sliding relative to the cover plate; and

a support component, configured to be attached to the flexible display panel, wherein at least one area of the support component is provided with a protrusion along a width direction of the flexible display panel, and the protrusion is located in the sliding groove for maintaining a gap between the flexible display panel and the cover plate during a sliding process.

2. The flexible display module of claim 1 , wherein the support component is provided with hollow portions on positions corresponding to the first bending area and the second bending area.

3. The flexible display module of claim 2 , wherein a shape of the hollow portions includes at least one of a square hole, a round hole, a convex elongated shape, and a concave elongated shape.

4. The flexible display module of claim 1 , wherein the support component is not provided with a protrusion on positions corresponding to the first bending area and the second bending area.

5. The flexible display module of claim 4 , wherein the sliding groove is discontinuous.

6. The flexible display module of claim 1 , wherein a length of the support component is equal to or greater than a length of the flexible display panel.

7. The flexible display module of claim 2 , wherein the flexible display module further comprises a functional element, and the functional element is disposed on a side of the flexible display panel away from the cover plate, and is fixedly connected to the housing.

8. The flexible display module of claim 7 , wherein the flexible display panel further includes a hole defined in the first bending area, and the hole is configured to expose the functional element when the flexible display panel slides to a specific position.

9. The flexible display module of claim 8 , wherein the hole penetrates the support component.

10. The flexible display module of claim 9 , wherein the hole and one of the hollow portions at least partially overlap.

11. The flexible display module of claim 8 , wherein lengths of the first bending area and the second bending area are equal to a sliding distance when the flexible display panel slides to a specific position.

12. The flexible display module of claim 1 , wherein each of the rolling components includes a roller.

13. The flexible display module of claim 1 , wherein a lubricating layer is provided in the gap between the flexible display panel and the cover plate.

14. The flexible display module of claim 13 , wherein the lubricating layer is coated on a surface of the flexible display panel and/or a surface of the cover plate.

15. The flexible display module of claim 14 , wherein material of the lubricating layer includes at least one of transparent optical glue and transparent grease.

16. The flexible display module of claim 1 , wherein the support component is attached to a side of the flexible display panel away from the cover plate.

17. The flexible display module of claim 16 , wherein the support component includes a stainless steel film.

18. The flexible display module of claim 1 , wherein the support component is attached to a side of the flexible display panel facing the cover plate.

19. The flexible display module of claim 18 , wherein the support component includes ultra-thin glass.

20. A flexible display device, comprising: the flexible display module according to claim 1 .
