In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0034] As shown in Figure 1 and Figure 2 The present embodiment provides an electronic device, which comprises a flexible screen rotating structure, the flexible screen rotating structure comprising a bottom frame 1 and two transmission components 2.

[0035] Specifically, the two transmission components 2 are symmetrically arranged on both sides of the bottom frame 1, and a symmetry plane is formed between the two transmission components 2. Each transmission component 2 comprises a shell connecting rod 21 and a support plate 22. The first end of the shell connecting rod 21 is rotationally connected to the bottom frame 1, and the second end of the shell connecting rod 21 is rotationally connected to the first end of the support plate 22, which is used to support the flexible screen. The end surface of the bottom frame 1 is provided with a sliding groove 11, which comprises a vertical groove 111 and a horizontal groove 112 that are in communication with each other. The horizontal groove 112 extends from the vertical groove 111 to the side close to the symmetry plane. The second end of the support plate 22 is provided with a protrusion 224, which is slidingly connected to the sliding groove 11.

[0036] When the flexible screen is switched from a flat state of 180° to a folded state, the support plate 22 and the shell connecting rod 21 jointly rotate relative to the bottom frame 1 in the direction close to the symmetry plane. During this process, the second end of the support plate 22 has two displacements. First, the first end of the support plate 22 rotates relative to the second end of the shell connecting rod 21, so that the protrusion 224 slides from the top of the vertical groove 111 to the bottom of the vertical groove 111. Then, the support plate 22 and the shell connecting rod 21 continue to move simultaneously, so that the protrusion 224 slides from the bottom of the vertical groove 111 to the horizontal groove 112, and slides to the end of the horizontal groove 112 away from the vertical groove 111. This reduces the distance between the second ends of the two support plates 22, and realizes the formation of a water drop shape of the flexible screen after bending, which is beneficial to realize thinning. Furthermore, the sliding groove 11 plays a guiding role for the protrusion 224, improving the reliability and stability of the flexible screen during rotation.

[0037] In this embodiment, the two transmission components 2 are symmetrically arranged along the first direction on both sides of the bottom frame 1. At the same time, the bottom frame 1 is provided with a transmission component 2 at both ends along the second direction, i.e. this embodiment comprises four transmission components 2 in total, improving the structural reliability and bending accuracy of the flexible screen during bending. In this embodiment, the first direction is X, and the second direction is Y. The first direction is perpendicular to the second direction.

[0038] Further, as shown in Figures 1-4 the sliding groove 11, the support wall 12 can support the support plate 22. In the Y direction, the support wall 12 is located between the protrusion 224 and the second end of the shell connecting rod 21, and the support wall 12 exerts a reaction force on the support plate 22 to make the support plate 22 rotate relative to the shell connecting rod 21. Among them, when the protrusion 224 slides in the horizontal groove 112, the support wall 12 has no contact with the support plate 22, so the support plate 22 has no relative movement with the shell connecting rod 21, and the two jointly rotate. Only when the protrusion 224 slides in the vertical groove 111, the support wall 12 drives the support plate 22 to rotate relative to the shell connecting rod 21.

[0039] Preferably, the support wall 12 is provided with a relief groove 13, and at least a portion of the housing link 21 is arranged in the relief groove 13. That is, the first end of the housing link 21 extends to a mounting portion matching the relief groove 13 in a direction away from the symmetry plane, and then continues to extend outwardly to be connected with the first end of the support plate 22. On one hand, when the protrusion 224 slides in the vertical slot 111, the mounting portion of the housing link 21 is embedded in the relief groove 13, and the support wall 12 only abuts against the support plate 22 to avoid the housing link 21, so as to realize the rotation of the support plate 22 relative to the housing link 21; on the other hand, when the flexible screen is in a flat state, the housing link 21 is embedded in the relief groove 13, so as to reduce the thickness of the electronic device.

[0040] Further preferably, one of the second end of the housing link 21 and the first end of the support plate 22 is provided with a first arc-shaped groove 211, and the other is provided with an arc-shaped wall 222, and the arc-shaped wall 222 is rotationally connected in the first arc-shaped groove 211. In the embodiment, the second end of the housing link 21 is provided with the first arc-shaped groove 211, and the first end of the support plate 22 is provided with the arc-shaped wall 222, and the arc-shaped wall 222 slides in the first arc-shaped groove 211, so as to realize the rotationally connecting the second end of the housing link 21 with the first end of the support plate 22.

[0041] Further preferably, the sliding groove 11 is arranged on the end wall of the bottom frame 1, and the support plate 22 is provided with a first relief hole 221 for avoiding the end wall of the bottom frame 1.

[0042] In the embodiment, the transverse slot 112 is formed as an arc-shaped transverse guide slot, and the axis of the arc-shaped transverse guide slot is collinear with the rotation axis of the first end of the housing link 21 relative to the bottom frame 1. When the protrusion 224 slides in the transverse slot 112, the support plate 22 and the housing link 21 do not rotate relative to each other, and the support plate 22, the protrusion 224 and the housing link 21 jointly rotate around the first end of the housing link 21 relative to the rotation axis of the bottom frame 1, so as to realize the guiding effect of the arc-shaped transverse guide slot on the protrusion 224, and prevent over-constraint.

[0043] The vertical slot 111 is formed as an arc-shaped vertical guide slot, and the arc-shaped vertical guide slot matches the movement track of the protrusion 224, so as to realize the guiding effect of the arc-shaped vertical guide slot on the protrusion 224, and prevent over-constraint.

[0044] Further, as shown in FIG. 6, the first end of the housing link 21 is provided with a first arc-shaped groove 211, and the first end of the support plate 22 is provided with an arc-shaped wall 222 rotationally connected in the first arc-shaped groove 211. Figure 3 and Figure 4As shown, the first end of the shell connecting rod 21 is provided with a transmission part 212, the transmission part 212 is rotationally connected to the bottom frame 1, the transmission part 212 is provided with a helical gear 2121, the bottom frame 1 is provided with a helical gear 3, the first end of the shell connecting rod 21 is perpendicular to the axis of the helical gear 3 relative to the rotation axis of the bottom frame 1, the axis of the helical gear 3 is located on the symmetry plane, and the two sides of the helical gear 3 are respectively meshed with the helical gears 2121 of the two shell connecting rods 21. The two transmission parts 2 are drivingly connected through a helical gear 3, when the flexible screen switches between the flat state and the folded state, the helical gear 2121 of the transmission part 212 of one side transmission part 2 meshes with one side of the helical gear 3, and the helical gear 2121 of the transmission part 212 of the other side transmission part 2 meshes with the other side of the helical gear 3, so that the two support plates 22 arranged in the first direction can be synchronously rotated, and the horizontal rotation can be converted into vertical rotation, the structure is compact, stable, simple, space-saving, etc.

[0045] Preferably, the support plate 22 is provided with a second avoiding hole 223 for avoiding the transmission part 212.

[0046] The flexible screen rotating structure further comprises a middle plate 4, the middle plate 4 is installed on the bottom frame 1, the middle plate 4 is located between the two support plates 22, and the middle plate 4 is used for supporting the flexible screen. By adopting the above transmission structure, the up and down displacement of the middle plate 4 can be avoided during the folding of the flexible screen, the thickness of the bottom frame 1 can be reduced, and the strength of the helical gear 3 can be increased.
