1. A collapsible support structure, comprising: at least two plane supporting parts and connect the support portion of buckling between two adjacent plane supporting parts, wherein:

the bending supporting part comprises a bending framework and a shielding assembly arranged on the outer side of the bending framework, and the shielding assembly comprises a central part, a movable plate, a fixed plate, a first swing wing and a second swing wing which are symmetrically arranged relative to the central part; the central member having end walls along both ends of a folding axis of the foldable support structure; the first swing wing is rotationally connected with the central component, and the second swing wing is rotationally connected with the central component; the fixing plate is fixed with the central part; the movable plate is positioned between the fixed plate and the first swing wing and the second swing wing, an elastic part is arranged between the movable plate and the fixed plate, and the elastic part is in a compressed state; the movable plate is abutted against one end, facing the second swing wing direction, of the first swing wing along the direction of the fixed plate facing the central component, and the movable plate is abutted against one end, facing the first swing wing direction, of the second swing wing;

the plane supporting part comprises a first pressure rod and a second pressure rod, the first pressure rod is abutted against the first swing wing to drive the first swing wing to swing along with the opposite swinging of the plane supporting part, the second pressure rod is abutted against the second swing wing to drive the second swing wing to swing, and the first swing wing and the second swing wing swing oppositely to enable the foldable supporting structure to be unfolded; along with the relative swing of the plane supporting part, the first swing wing and the second swing wing relatively swing under the abutting pressure of the movable plate, so that the foldable supporting structure is folded.

2. The collapsible support structure of claim 1 wherein the planar support section comprises a support frame and an outer shell having a shield portion that shields the buckling support section when the collapsible support structure is deployed.

3. The foldable support structure of claim 2, wherein the first lever is a set distance from the first swing wing and the second lever is a set distance from the second swing wing when the foldable support structure is folded; when the foldable supporting structure is unfolded to the position where the shielding part shields the first connecting seam and the second connecting seam, the first pressing rod abuts against the first swing wing, and the second pressing rod abuts against the second swing wing.

4. The foldable support structure of claim 1, wherein a surface of the first swing wing, a surface of the central member, and a surface of the second swing wing smoothly transition on a side facing away from the bending skeleton when the foldable support structure is folded.

5. The collapsible support structure of claim 1 wherein the fixing plate is in screw connection with the central member.

6. The foldable support structure of claim 1, wherein the bend support further comprises a movable plate guide extending in a direction from the fixed plate toward the central member, the movable plate having a guide that mates with the movable plate guide.

7. The foldable support structure of claim 6, wherein the movable plate guiding structure is a guiding post and the guiding portion is a guiding hole or a guiding groove, or the movable plate guiding structure is a guiding hole or a guiding groove and the guiding portion is a guiding post.

8. The collapsible support structure of claim 1 wherein the first swing wing is pivotally connected to the central member and the second swing wing is pivotally connected to the central member.

9. The collapsible support structure of claim 1 wherein the first swing wing has a first arcuate mounting section and the second swing wing has a second arcuate mounting section, the central component having a third arcuate mounting section that is fittingly mounted to the first arcuate mounting section, the central component having a fourth arcuate mounting section that is fittingly mounted to the second arcuate mounting section.

10. A display device comprising a display screen and a foldable support structure according to any one of claims 1 to 9, wherein the display screen is fixed to a side of the foldable support structure remote from the barrier assembly.
