When the flexible screen is assembled on the flexible screen bracket 10, the telescopic part 12 in the contracted state can be unfolded by applying a pulling force to the telescopic part 12 far away from the winding part 11, and meanwhile, the flexible screen is pulled out from the inner cavity of the winding part 11, so that the display area of the flexible screen is gradually increased along with the unfolding of the telescopic part 12; or by applying a pushing force to the expansion part 12 toward the rolling part 11, the expansion part 12 in the unfolded state can be contracted, and at the same time, the rolling part 11 accommodates the curled portion of the flexible screen into the inner cavity, so that the display area of the flexible screen is gradually reduced along with the contraction of the expansion part 12, and the flexible screen always abuts against the surface of the contraction part 12 under the action of the pulling stress provided by the rolling part 11 in the contracted state or the unfolded state.
Referring to fig. 7, when the flexible screen bracket 10 is used on the display device 1, the circuit board 20, the battery, etc. of the display device 1 are fixed on the back surface of the telescopic portion 12, that is, the telescopic portion 12 can be used as the housing of the body of the display device 1, so that the winding portion 11 is located on the outer side of the body, and the thickness of the body depends on the thicknesses of the components of the telescopic portion 12, the circuit board 20, the battery, etc. and is irrelevant to the thickness of the winding portion 11, thereby effectively solving the technical problem that the size of the scroll restricts the thickness reduction of the body, and being beneficial to the development of the display device 1 with the flexible screen towards the light and thin direction.
Alternatively, referring to fig. 1 to 3, as a specific embodiment of the flexible screen support provided by the present application, the telescopic portion 12 includes multiple sections of guide rails nested in sequence along a direction away from the winding portion 11, wherein a first section of guide rail close to the winding portion 11 is connected to an outer wall of the winding portion 11, a last section of guide rail away from the winding portion 11 is used for being connected to an extended end of the flexible screen exposed outside the winding portion 11, two adjacent sections of guide rails are slidably connected, and support walls of the multiple sections of guide rails are coplanar and can jointly support the flexible screen, that is, support walls of the multiple sections of guide rails can together form a support surface for supporting the flexible screen.

Specifically, the force application portion 13 may be fixedly connected to one end of the last section of the guide rail of the telescopic portion 12, which is far away from the winding portion 11, through welding, screwing, welding, bonding, or an integrated molding, so that the user can grasp the guide rail, and the user can apply an external force to the telescopic portion 12, and the extending end of the flexible screen can be fixed. The last section of guide rail of the telescopic part 12 is driven by the force application part 13 to drive the rear section of guide rail of the two adjacent sections of guide rails to slide out of the front section of guide rail so as to realize the unfolding of the telescopic part 12 along the unfolding direction of the flexible screen.
Alternatively, referring to fig. 1 to 3, as a specific embodiment of the flexible screen bracket provided by the present application, the telescopic portion 12 includes a plurality of guide rail groups 120, and the plurality of guide rail groups 120 are sequentially arranged along the length direction of the winding portion 11, and each guide rail group 120 includes a plurality of guide rails. That is, the telescopic portion 12 is formed by sequentially arranging a plurality of guide rail groups 120 along a direction perpendicular to the unfolding direction of the flexible screen, two adjacent guide rail groups 120 are mutually parallel and are fixedly connected through respective first-section guide rails, and each guide rail group 120 realizes self extension or shortening through mutual sliding of a plurality of sections of guide rails. Thus, the telescopic part 12 is formed by the plurality of guide rail groups 120, so that the telescopic action of the telescopic part 12 can be more stable and smooth.
Alternatively, referring to fig. 2 and 8, as an embodiment of the flexible screen bracket provided by the present application, the multi-section guide rail connected to the winding portion 11 is integrally formed. I.e., the first section of the guide rail of the plurality of guide rail sets 120 is integrally formed, which is beneficial to improving the structural strength of the telescopic portion 12, and can provide a more stable supporting platform for the circuit board 20.
Alternatively, referring to fig. 2 to 5, as a specific embodiment of the flexible screen support provided by the present application, each guide rail set 120 includes three guide rails, which are a first guide rail 121, a second guide rail 122 and a third guide rail 123, respectively, it is understood that the first guide rail of the guide rail set 120 is the first guide rail 121, and the last guide rail of the guide rail set 120 is the third guide rail 123; the first guide rail 121 includes a first bottom wall 1211, two first side walls 1212, two first supporting walls 1213, and two first assembling walls 1214, where the two first side walls 1212 extend outwardly from two long edges of the first bottom wall 1211, which are distributed in parallel, in a direction non-parallel to the first bottom wall 1211, the first supporting walls 1213 extend from edges of the first side walls 1212, which are far from the first bottom wall 1211, toward the other first supporting walls 1213 in a direction parallel to the first bottom wall 1211, and the first assembling walls 1214 extend from edges of the first supporting walls 1213, which are far from the first side walls 1212, toward the first bottom wall 1211 in an arc shape; the second rail 122 includes a second bottom wall 1221, two second fitting walls 1222, two second supporting walls 1223, and two third fitting walls 1224, the two second fitting walls 1222 extend from two long edges of the second bottom wall 1221, which are distributed in parallel, to an arc away from the second bottom wall 1221, the second supporting walls 1223 extend from edges of the second fitting walls 1222, which are away from the second bottom wall 1221, to another second supporting wall 1223 in a direction parallel to the second bottom wall 1221, the third fitting walls 1224 extend from edges of the second supporting walls 1223, which are away from the second fitting walls 1222, to an arc of the second bottom wall 1221, and the second fitting walls 1222 enclose the first fitting walls 1214 to form the first chute 124; the third guide rail 123 includes a third supporting wall 1231 and two fourth assembling walls 1232, the two fourth assembling walls 1232 extend from two long edges of the third supporting wall 1231, which are parallel to each other, in a direction away from the third supporting wall 1231, and the fourth assembling walls 1232 and the third assembling walls 1224 enclose to form the second chute 125. Thus, the three sections of guide rails form the guide rail group 120, which can effectively increase the unfolding area of the telescopic part 12, and is beneficial to the flexible screen to obtain a larger ratio of the maximum display area to the minimum display area. Of course, in other embodiments of the present application, each guide rail set 120 may include two or more guide rails, where the number of guide rails is two, the structure of the first guide rail is consistent with the first guide rail 121, the structure of the second guide rail is consistent with the third guide rail 123, where the number of guide rails is three or more, the structure of the first guide rail is consistent with the first guide rail 121, the structure of the last guide rail is consistent with the third guide rail 123, and the structure of the remaining guide rails is consistent with the second guide rail 122.
Meanwhile, each guide rail group 120 further includes a plurality of balls (not shown) respectively received in the first and second sliding grooves 124 and 125, and the plurality of balls are respectively interference-fitted with the first and second sliding grooves 124 and 125, i.e., the diameters of the balls are equal to or greater than the maximum distance between the first and second fitting walls 1214 and 1222, and the diameters of the balls are equal to or greater than the maximum distance between the third and fourth fitting walls 1224 and 1232. In this way, a sliding damper is generated between the first rail 121 and the second rail 122 and between the second rail 122 and the third rail 123, the sliding damper being balanced with the tensile stress of the winding portion 11, and when a tensile force is applied to the force application portion 13 away from the winding portion 11, the tensile force breaks the balance, so that the third rail 123 slides out of the rail cavity of the second rail 122, the second rail 122 slides out of the rail cavity of the first rail 121, and the flexible screen expands; when a pushing force is applied to the force application part 13 towards the winding part 11, the pulling force breaks the balance, so that the third guide rail 123 slides into the guide rail cavity of the second guide rail 122, the second guide rail 122 slides into the guide rail cavity of the first guide rail 121, and the flexible screen is contracted; and because the first guide rail 121 is in rolling connection with the second guide rail 122 through the balls, and the second guide rail 122 is in rolling connection with the second guide rail 122 through the balls, friction resistance can be effectively reduced, abrasion between two adjacent guide rails can be reduced, and the service life of the guide rail group 120 is prolonged. Of course, rollers may be used instead of balls in other embodiments of the application, as the case may be and as desired, and are not limited solely herein.
Optionally, referring to fig. 5, as an embodiment of the flexible screen bracket provided in the present application, the first guide rail 121 further includes two first transition walls 1215, and the first transition walls 1215 are connected between the first support wall 1213 and the first assembly wall 1214; the second rail 122 further comprises two second transition walls 1225 and two third transition walls 1226, wherein the second transition walls 1225 are connected between the second fitting wall 1222 and the second supporting wall 1223 for abutment with the first transition walls 1215, and the third transition walls 1226 are connected between the second supporting wall 1223 and the third fitting wall 1224; the third rail 123 further comprises two fourth transition walls 1233, the fourth transition walls 1233 being connected between the third support wall 1231 and the fourth fitting wall 1232 for abutment with the third transition wall 1226. Specifically, in the same rail set 120, the first transition wall 1215 is parallel to the second transition wall 1225 and the third transition wall 1226 is parallel to the fourth transition wall 1233. This advantageously increases the support area of the first rail 121 for the second rail 122 and the support area of the second rail 122 for the third rail 123, effectively avoiding the drop of the second support wall 1223 relative to the first support wall 1213 and the drop of the third support wall 1231 relative to the second support wall 1223 during sliding, thereby ensuring that the first and second support walls 1213, 1223 are coplanar with the third support wall 1231.
Alternatively, referring to fig. 2, as an embodiment of the flexible screen bracket provided in the present application, after the expansion portion 12 is expanded, the latter one of the two adjacent guide rails has a supporting portion 1200 that is limited in the guide rail cavity of the former guide rail. That is, after the adjacent two sections of guide rails complete the relative sliding of the maximum distance, the supporting portion 1200 of the next section of guide rail is always kept in the guide rail cavity of the previous section of guide rail, so that the previous section of guide rail has enough supporting force for the next section of guide rail, and the supporting walls of the sections of guide rails are kept in good coplanarity when the telescopic portion 12 is completely unfolded. The length of the support portion 1200 is L, and the specific value of L may be determined according to the structural strength of the flexible screen bracket 10.
