[0002] Currently, curled flexible structures primarily utilize hinges and inverted trapezoidal support blocks, resulting in significant stress concentration at the bends of the support blocks. Curled support structures employ a self-supporting solution with structural limits, which can be ineffective due to machining and assembly tolerances. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention proposes a flexible curling display mechanism.

[0004] The flexible curling display mechanism of the present invention includes a flexible display module, one end of the flexible display module is a curling end, and the curling end is connected to the whole machine shaft through a driving shaft, wherein a limiting rod and a continuous elastic support member are provided on the lower bottom surface of the flexible display module, and the continuous elastic support member includes a plurality of limiting grooves arranged parallel to the curling direction of the flexible display module, and at least the end of the limiting rod is correspondingly arranged in the limiting groove. When the flexible display module is unfolded, the end of the limiting rod can be moved from the top of the limiting groove to the bottom of the limiting groove by traction of the driving shaft. When the flexible display module is rolled up, the end of the limiting rod can be moved from the bottom of the limiting groove to the top of the limiting groove.

[0005] In one embodiment, a curling track is provided on the upper edge of the whole machine shaft, and the curling end is embedded in the curling track. One end of the two driving shafts is respectively fixed to the two ends of the whole machine shaft, and can rotate clockwise or counterclockwise with the fixed end as a fulcrum. A sliding groove for the limiting rod to be embedded is provided along the axial direction of the driving shaft, and the end of the limiting rod located at the curling end of the flexible display module is embedded in the sliding groove of the driving shaft, so that when the driving shaft rotates, the flexible display module is driven to unfold or reel through the limiting rod.

[0006] In one embodiment, the limiting groove of the continuous elastic support member includes a dovetail groove with a triangular cross-section at the upper part and a locking groove with a circular cross-section at the lower part. The dovetail groove is connected to the locking groove. When the flexible display module is unfolded, the limiting rod can move downward from the dovetail groove to the locking groove. When the flexible display module is rolled up, the limiting rod can move upward from the locking groove to the dovetail groove.

[0007] In one embodiment, the limit rod includes a traction limit rod located at the end of the curled end and a movable limit rod arranged parallel to the traction limit rod, the traction limit rod is fixed to the lower bottom surface of the flexible display module, the end of the traction limit rod is embedded in the slide groove of the drive shaft, and the movable limit rod is embedded in the continuous elastic support member.

[0008] In one embodiment, a support bar is provided below the movable limiting rod, and a plurality of the movable limiting rods are connected as a whole via the support bar.

[0010] In one embodiment, the drive shaft is driven by a motor or a torsion spring to rotate clockwise or counterclockwise around its fixed end.

[0011] In one embodiment, the end of the movable limiting rod is cylindrical, the middle part is a quadrilateral flat plate, the support bar is fixed below the quadrilateral flat plate, and the cylindrical end is embedded in the limiting groove of the continuous elastic support member.

[0012] In one embodiment, the continuous elastic support member is an integrally formed structure made of a flexible material, and adjacent circular limiting grooves are connected together.

[0013] In one embodiment, the extending direction of the limiting groove is perpendicular to the curling direction of the flexible display module, and the movable limiting rod is entirely embedded in the limiting groove.

[0014] In one embodiment, the support bar is made of metal, PI, plastic (ABS, PC, etc.), or composite materials such as carbon fiber.

[0015] Compared with the prior art, the flexible curling display mechanism of the present invention adopts a dovetail-type continuous elastic support member with a built-in movable limiting rod. When in the unfolded state, the movable limiting rod enters the elastic card slot above the support member to limit the movement of the support member; in the retracted state, the movable limiting rod enters the movable groove below the support member and acts as a guide column. Under the limiting action of the track, the flexible display module is driven to form a curled state, and the elastic card slot spacing of the support member of the flexible display module can be reduced. The continuous elastic support member has no obvious stress concentration on the curling module, and can absorb the misalignment of different radii by utilizing elastic deformation; and the movable limiting rod can guide and limit the flexible module to form multiple circles of curling, and the movable limiting rod can enter the support member slot to play a support limiting role.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, as long as no conflict exists, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.

[0026] Parts not described in the present invention can be implemented by adopting or drawing on existing technologies.

[0027] like Figure 1 and Figure 2As shown, the flexible curling display mechanism of the present invention includes a flexible display module 1, one end of the flexible display module is a curling end, and the curling end is connected to the whole machine shaft 4 through a driving shaft 3, wherein a limiting rod 2 and a continuous elastic support member 6 are provided on the lower bottom surface of the flexible display module, and the continuous elastic support member includes a plurality of limiting grooves arranged parallel to the curling direction of the flexible display module 1, and at least the end of the limiting rod 2 is correspondingly arranged in the limiting groove. When the flexible display module 1 is unfolded, the end of the limiting rod 2 can be moved from the top of the limiting groove to the bottom of the limiting groove by pulling the driving shaft 3. When the flexible display module is rolled up, the end of the limiting rod 2 can be moved from the bottom of the limiting groove to the top of the limiting groove.

[0028] In a preferred embodiment, a curling track is provided on the upper edge of the whole machine shaft 4, and the curling end is embedded in the curling track. One end of the two drive shafts 3 is respectively fixed to the two ends of the whole machine shaft 4. The drive shaft 3 can rotate clockwise or counterclockwise with the fixed end as a fulcrum. A slide groove for the limit rod 2 to be embedded is provided along the axial direction of the drive shaft 3. The end of the limit rod 2 (i.e., the traction limit rod 21) located at the curling end of the flexible display module 1 is embedded in the slide groove of the drive shaft 3, so that when the drive shaft 3 rotates, the flexible display module 1 is driven to unfold or reel by the traction limit rod 21.

[0029] like Figure 2 and Figure 3 As shown, the limiting groove of the continuous elastic support member 6 includes a dovetail groove with a triangular cross-section at the top and a circular locking groove at the bottom. The dovetail groove is connected to the locking groove. When the flexible display module 1 is unfolded, the limiting rod 2 (movable limiting rod 22) can move downward from the dovetail groove into the locking groove. The movable limiting rod 22 is caught by the cylindrical deformation space of the continuous elastic support member 6, preventing the continuous elastic support member from deforming and bending, forming a support structure after unfolding, thereby realizing the unfolding movement of the flexible display module. When the flexible display module 1 is retracted, the movable limiting rod 22 can move upward from the locking groove into the dovetail groove. The cylindrical locking groove of the continuous elastic support member 6 loses its limit. After entering the curling zone, the deformation space of the locking groove is used to absorb the misalignment of different radii, thereby realizing the retracting movement of the flexible display module.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, in a preferred embodiment, the limit rod 2 includes a traction limit rod 21 located at the end of the curled end and a movable limit rod 22 arranged parallel to the traction limit rod 21, the traction limit rod 21 is fixed to the lower bottom surface of the flexible display module 1, the end of the traction limit rod 21 is embedded in the slide groove of the drive shaft 3, and the movable limit rod 22 is embedded in the continuous elastic support member.

[0031] In a preferred embodiment, a support bar 5 made of metal or PI material is provided below the movable limiting rod 22 , and a plurality of movable limiting rods 22 are connected as a whole via the support bar 5 .

[0032] In a preferred embodiment, the traction limiting rod 21 is fixed to the lower bottom surface of the flexible display module 1 by bonding, and the continuous elastic support member 6 is fixed to the lower bottom surface of the flexible display module 1 by bonding.

[0033] More preferably, the drive shaft 3 is driven by a motor or a torsion spring to rotate clockwise or counterclockwise around its fixed end.

[0034] like Figure 4 As shown, the movable limit rod 22 has cylindrical ends and a rectangular flat plate 23 in the middle. The cylindrical ends are embedded in the limit slots of the continuous elastic support member 6. The movable limit rod 22 is connected to the support bar (made of metal, PI, plastic (such as ABS PC), or composite materials such as carbon fiber) below the rectangular flat plate 23 to prevent the flexible MDL from deforming in the opposite direction. The movable limit rod 22 has cylindrical ends and is placed in the limit slots of the continuous elastic support member 6, extending beyond the edges of the limit slots to limit the position of the entire machine's curling track.

[0035] In a preferred embodiment, the continuous elastic support member 6 is an integrally formed structure made of a flexible material, and adjacent circular positioning grooves are connected together.

[0036] In an optional embodiment, the extending direction of the limiting groove is perpendicular to the curling direction of the flexible display module 1 , and the movable limiting rod 22 can be entirely embedded in the limiting groove.

[0037] Below, according to Figure 2-Figure 4 The movement process of the flexible curling display mechanism of the present invention is described in detail.

[0038] Driven by a motor, torsion spring, or other force, the drive shaft 3 rotates counterclockwise around the center of rotation of the entire device (its fixed end), driving the traction limit rod 21 to move counterclockwise along the entire device's winding track, thereby driving the continuous elastic support member and the movable limit rod 22 to move counterclockwise along the entire device's winding track. When the continuous elastic support member 6 and the movable limit rod move to the winding exit position, the movable support rod moves upward along the ascending track from the lower retaining groove of the continuous elastic support member to the upper triangular dovetail groove. The retaining groove of the continuous elastic support member is no longer restrained. After entering the winding zone, the retaining groove's deformation space can absorb misalignment of different radii, thereby achieving the winding movement of the flexible display module.

[0039] Drive shaft 3, driven by a motor, torsion spring, or other force, rotates clockwise around the center of rotation of the entire device, driving traction limit rod 21 to move clockwise along the entire device's winding track, thereby driving the continuous support member and movable hook to move clockwise along the entire device's winding track. When the continuous elastic support member 6 and movable limit rod 22 move to the winding exit position, the movable limit rod 22 moves down along the descending track from the dovetail groove above the continuous elastic support member to the locking groove below. The movable limit rod 22 blocks the deformation space of the continuous elastic support member, preventing the continuous elastic support member 6 from deforming and bending, forming a support structure after unfolding, thereby realizing the unfolding movement of the flexible display module.

[0040] Its continuous elastic support has no obvious stress concentration on the flexible curling module, and can absorb the misalignment of different radii by utilizing elastic deformation; and the movable limiting rod can guide and limit the flexible module to form multiple circles of curling. The movable limiting rod can enter the slot of the elastic support to play a supporting and limiting role, and utilizes elastic positioning to avoid support failure caused by assembly and processing tolerances.
