Referring to fig. 1 to 4, a flexible display device 100 is provided in an embodiment of the present disclosure. The flexible display device 100 includes a flexible display screen 102, a housing 104, and a support structure 106. A support structure 106 connects the housing 104 and one end of the flexible display screen 102. The support structure 106 is capable of telescoping the flexible display screen 102 relative to the housing 104 to switch back and forth between the deployed state and the retracted state. The support structure 106 includes a slide rail assembly 108. The slide rail assembly 108 includes a plurality of slide rail sets 110 arranged along a direction B perpendicular to the telescoping direction a of the support structure 106. The plurality of sliding rail sets 110 together form a supporting plane 112 for supporting the flexible display screen 102, and the supporting plane 112 in the unfolded state and the supporting plane 112 in the retracted state are in the same plane.

In the flexible display device 100 according to the embodiment of the application, the supporting plane 112 formed by the plurality of sliding rail sets 110 of the supporting structure 106 is the same plane in the unfolding state and the folding state of the supporting structure 106, so that the flexible display screen 102 can be supported on the whole surface, and the flatness of the flexible display screen 102 on the flexible display device 100 can be ensured, thereby improving the supporting effect of the flexible display screen 102.

In particular, the flexible display device 100 may be applied to electronic devices including, but not limited to, smart phones, tablet computers, notebook computers, and the like.

Referring to fig. 5-12, in the present embodiment, the support structure 106 further includes a bottom cover assembly 114, a back cover 116, a rollable support plate 118, and a fastener 120.

The slide rail assembly 108 is disposed on the lower cover assembly 114. The lower cover assembly 114 connects the housing 104 and the sled assembly 108 and is capable of telescoping in unison with the sled assembly 108. Thus, the bottom cover assembly 114 can increase the stability of the sliding rail assembly 108 during sliding, and at the same time, can also increase the structural strength of the flexible display device 100.

Specifically, in the present embodiment, one end of the bottom cover assembly 114 is fixedly connected to one end of the slide rail assembly 108, and the other end of the bottom cover assembly 114 is fixedly connected to the other end of the slide rail assembly 108. One end of the lower cover assembly 114 is fixedly connected to the housing 104. This ensures that when the lower cover assembly 114 is moved, the slide rail assembly 108 is also moved synchronously, facilitating the deployment and retrieval of the flexible display device 100.

In the present embodiment, the support structure 106 includes a first stationary shaft 122 and a second stationary shaft 124. The first fixing shaft 122 and the second fixing shaft 124 are respectively located at two ends of the sliding rail assembly 108. The plurality of slide rail sets 110 are coupled by a first fixed shaft 122 and a second fixed shaft 124. Therefore, the sliding rail sets 110 are connected through the two fixed shafts, and the connecting structure is simple.

Specifically, each track set 110 includes a plurality of slidably coupled track hinges 126, and more specifically, in the illustrated example, the number of track hinges 126 is four, namely a first track hinge 128, a third track hinge 130, a fourth track hinge 132, and a second track hinge 134. The first section of slide rail hinge 128, the third section of slide rail hinge 130, the fourth section of slide rail hinge 132 and the second section of slide rail hinge 134 are sequentially connected in series along the telescopic direction a of the support structure.

The first section of slide rail hinge 128 has a first through hole 136, and the first fixing shaft 122 penetrates the first through hole 136. The second section of slide rail hinge 134 is provided with a second through hole 138, and the second fixing shaft 124 penetrates through the second through hole 138. Thus, the first fixing shaft 122 penetrates through the first through holes 136 of the plurality of slide rail sets 110, and the second fixing shaft 124 penetrates through the second through holes 138 of the plurality of slide rail sets 110, so as to connect the plurality of slide rail sets 110 to form the slide rail assembly 108.

In one example, the first stationary shaft 122 is a semi-elliptical cylinder and the second stationary shaft 124 is an elliptical cylinder. The first through hole 136 has a half-flat oval shape corresponding to the shape of the first stationary shaft 122, and the second through hole 138 has a flat oval shape corresponding to the shape of the second stationary shaft 124. In this way, the sliding of the plurality of sliding rail sets 110 on the first fixing shaft 122 and the second fixing shaft 124 can be avoided, and meanwhile, the first fixing shaft 122 of the semi-elliptic cylinder and the second fixing shaft 124 of the elliptic cylinder can be easily provided with the through holes. Of course, in other embodiments, the first and second

fixed shafts

122 and 124 may be selected from other suitable shapes, such as rectangular or prismatic.

The lower cover assembly 114 comprises a plurality of cover plates 140 in sliding connection, more specifically, in the example illustrated, the number of cover plates 140 is four, respectively: a first cover plate 142, a third cover plate 144, a fourth cover plate 146, and a second cover plate 148. The first cover plate 142 is provided with a plurality of first coupling posts 150, and the second cover plate 148 is provided with a plurality of second coupling posts 152. The first fixing shaft 122 is provided with a plurality of first coupling through holes 154, and the second fixing shaft 124 is provided with a plurality of second coupling through holes 156. The plurality of first connection through holes 154 are disposed corresponding to the plurality of first connection posts 150 and connected by fasteners 158, and the plurality of second connection through holes 156 are disposed corresponding to the plurality of second connection posts 152 and connected by fasteners 158. The first and second connecting

posts

150, 152 may be internally threaded, and the fastener 158 may be a screw that mates with the first and second connecting

posts

150, 152. In one example, the number of the first connection posts 150 and the first connection through holes 154 is four, and the number of the second connection posts 152 and the second connection through holes 156 is four. Of course, in other embodiments, the number of the first connection posts 150, the second connection posts 152, the first connection through holes 154, and the second connection through holes 156 may be selected according to actual needs, and it is only necessary to keep the number of the first connection posts 150 and the number of the first connection through holes 154 consistent, and the number of the second connection posts 152 and the number of the second connection through holes 156 consistent.

The housing 104 is provided with a plurality of third connection posts 160, and the second cover plate 148 is provided with a plurality of third connection through holes 162. The plurality of third connection through holes 162 are disposed corresponding to the plurality of third connection posts 160 and connected by the fastening members 158. Third connecting post 160 may be internally threaded and fastener 158 may be a screw configured to mate with third connecting post 160. In one example, the housing 104 is provided with three third connecting posts 160 and the second cover plate 148 is provided with three third connecting through holes 162. The number of the third connection posts 160 and the number of the third connection through holes 162 are the same. Of course, in other ways, the number of the third connecting posts 160 and the third connecting through holes 162 can be selected according to actual needs.

A rear cover 116 is secured to the end of the lower cover assembly 114 remote from the housing 104. The provision of the rear cover 116 may facilitate for operating the flexible display device 100 to switch back and forth between the deployed state and the retracted state. Specifically, the user can hold the back cover 116 with one hand and the housing 104 with the other hand, and then move the two hands relatively away from or closer to each other, so that the back cover 116 can drive the flexible display screen 102 and the slide rail assembly 108 to extend and retract, so as to switch the flexible display device 100 between the extended state and the retracted state.

Specifically, the rear cover 116 is fixed to the first cover plate 142 of the lower cover assembly 114. The first cover 142 is provided with a plurality of fourth connection posts 164, and the plurality of fourth connection posts 164 and the plurality of first connection posts 150 are disposed on opposite sides of the first cover 142 (see fig. 10 and 11). The rear cover 116 is provided with a plurality of fourth connecting through-holes 166. The plurality of fourth connecting through holes 166 and the plurality of fourth connecting posts 164 are correspondingly arranged and connected by the fasteners 158. Fourth connecting post 164 may be internally threaded and fastener 158 may be a screw configured to mate with fourth connecting post 164. In one example, the number of the fourth connection posts 164 and the fourth connection through holes 166 is four. The number of the fourth connection posts 164 and the number of the fourth connection through holes 166 are the same. The four fourth connection posts 164 are arranged in a rectangular shape, and the four fourth connection through holes 166 are arranged in a rectangular shape. Of course, in other ways, the number of the fourth connection posts 164 and the fourth connection through holes 166 can be selected according to actual needs.

In the embodiment of the present application, the bottom cover assembly 114 and the slide rail assembly 108, the bottom cover assembly 114 and the housing 104, and the rear cover 116 and the bottom cover assembly 114 are all fixedly connected by fasteners 158. In other embodiments, the rear cover 116 and the lower cover assembly 114 may be coupled by a first fixed shaft 122 and the slide rail assembly 108, the lower cover assembly 114, and the housing 104 may be coupled by a second fixed shaft 124. Specifically, the first and second

fixed shafts

122 and 124 are respectively located at both ends of the slide rail assembly 108. The plurality of slide rail sets 110 are coupled by a first fixed shaft 122 and a second fixed shaft 124. Through holes are formed in the side surfaces of the two sides of the first cover plate 142 and the rear cover 116 of the lower cover assembly 114, and the first fixing shaft 122 penetrates through the through holes in the side surfaces of the two sides of the first cover plate 142 and the through holes in the side surfaces of the two sides of the rear cover 116 to fix the rear cover 116 to the first cover plate 142 of the lower cover assembly 114. Thus, the rear cover 116 is fixedly connected to the lower cover assembly 114 and one end of the slide rail assembly 108. Through holes are formed in the second cover plate 148 of the lower cover assembly 114 and the two side surfaces of the shell 104, and the second fixing shaft 124 penetrates through the through holes in the two side surfaces of the second cover plate 148 and the through holes in the two side surfaces of the rear cover 116 so as to fixedly connect one end of the lower cover assembly 114 with the shell 104. Thus, the housing 104 is fixedly connected to the lower cover assembly 114 and the other end of the slide rail assembly 108.

The support plate 118 is carried on the support plane 112 and telescopes with the support structure 106. The flexible display screen 102 is carried on a support plate 118. In this manner, the support plate 118 may provide a flatter support surface for better support of the flexible display screen 102.

The flexible display screen 102 may be disposed on the support plate 118. The supporting plate 118 is fixedly connected to the flexible display screen 102, for example, the supporting plate 118 is fixedly adhered to the flexible display screen 102.

The fasteners 120 secure the support plate 118 to the slide rail assembly 108. Specifically, in one example, the fixing member 120 is a magnetic member, the rail hinge 126 of each rail set 110 is opened with a receiving hole 168, the fixing member 120 is located in the receiving hole 168, and the supporting plate 118 is made of a magnetically absorbable material. As the flexible display screen 102 is extended and retracted relative to the housing 104 to switch between the extended state and the retracted state, the support plate 118 is extended and retracted along with the flexible display screen 102, and the slide rail assembly 108 and the lower cover assembly 114 are also extended and retracted synchronously. In the present embodiment, the fixing member 120 is a magnet piece, and the support plate 118 is a magnetically attractable steel piece. In one example, each slide rail hinge 126 of each slide rail set 110 is opened with a receiving hole 168, and the fixing member 120 is located in the receiving hole 168.

Referring to fig. 6-8 again, each slide rail set 110 includes a plurality of slide rail hinges 126 connected in a sliding manner, and in two adjacent slide rail hinges 126, a groove 170 is disposed on a side surface of one slide rail hinge 126, and a protrusion 172 slidably engaged with the groove 170 is disposed on a side surface of the other slide rail hinge 126. In this way, the sliding fit between the protrusion 172 and the groove 170 connects two adjacent slide rail hinges 126, so that two adjacent slide rail hinges 126 can slide relatively to each other to extend and retract the slide rail assembly 108.

Further, at least one end of the groove 170 along the extension direction a of the supporting structure 106 is provided with a limiting portion 174. The limiting portion 174 can prevent the protrusion 172 from sliding out of the groove 170 when the two adjacent slide rail hinges 126 slide relatively. In the embodiment of the present application, the number of the slide rail hinges 126 is four, and they are respectively: the first section of track hinge 128, the third section of track hinge 130, the fourth section of track hinge 132 and the second section of track hinge 126 are sequentially arranged along the extension direction a of the support structure 106. The groove 170 of the first section of slide rail hinge 128 is in sliding connection with the projection 172 of the third section of slide rail hinge 130, the groove 170 of the third section of slide rail hinge 130 is in sliding connection with the projection 172 of the fourth section of slide rail hinge 132, and the groove 170 of the fourth section of slide rail hinge 132 is in sliding connection with the projection 172 of the second section of slide rail hinge 134. Thus, the four-section slide rail hinge 126 is slidably connected to extend and retract each slide rail set 110, i.e., the slide rail assembly 108.

In one example, the recess 170 of each slide rail hinge 126 is provided with a stop 174 at one end along the telescoping direction a of the support structure 106. Specifically, the limiting portion 174 of each slide hinge 126 is disposed at an end of the groove 170 near the housing 104. Thus, when the slide rail assembly 108 is extended and two adjacent slide rail hinges 126 cannot slide relatively at the position of the limiting portion 174, the protrusion 172 of one slide rail hinge 126 is caught by the limiting portion 174 of the other slide rail hinge 126, so that the protrusion 172 cannot slide out of the groove 170. In the present embodiment, the slide rail assembly 108 slides and retracts from the first section of slide rail hinge 128 toward the second section of slide rail hinge 134, for example, when the first section of slide rail hinge 128 and the third section of slide rail hinge 130 slide and retract, the third section of slide rail hinge 130 approaches the first fixed shaft 122, and when the third section of slide rail hinge 130 abuts against the first fixed shaft 122, the protrusion 172 of the third section of slide rail hinge 130 is still located in the groove 170 of the first section of slide rail hinge 128. Therefore, when the slide rail assembly 108 is retracted, the protrusion 172 will not slide out of the recess 170 even though the other end of each slide rail hinge 126 does not have the limiting portion 174.

In the present embodiment, each rail set 110 includes a first rail hinge 128, a third rail hinge 130, a fourth rail hinge 132, and a second rail hinge 126. Of course, in other embodiments, each set of rails 110 may include at least two sections of rail hinges 126. For example, when each slide rail set 110 includes the first slide rail hinge 128 and the second slide rail hinge 126, the groove 170 of the first slide rail hinge 128 and the protrusion 172 of the second slide rail hinge 134 may be slidably connected, or the protrusion 172 of the first slide rail hinge 128 and the groove 170 of the second slide rail hinge 134 may be slidably connected.

Referring to fig. 10-12 again, the bottom cover assembly 114 includes a plurality of cover plates 140 connected in a sliding manner, wherein in two adjacent cover plates 140, sliding grooves 176 are disposed on two side surfaces of one cover plate 140, and bosses 178 matched with and limiting the sliding grooves 176 are disposed on two side surfaces of the other cover plate 140. In this manner, the bosses 178 and the slots 176 act as a stop for the two cover plates 140.

In the illustrated example, the number of cover plates 140 is four, respectively: a first cover plate 142, a third cover plate 144, a fourth cover plate 146 and a second cover plate 148, the four cover plates 140 being aligned along the extension direction a of the support structure 106. The side surfaces of the two sides of the first cover plate 142 are provided with sliding grooves 176, the side surfaces of the two sides of the third cover plate 144 are provided with bosses 178 and sliding grooves 176, the side surfaces of the two sides of the fourth cover plate 146 are provided with bosses 178 and sliding grooves 176, and the side surfaces of the two sides of the second cover plate 148 are provided with bosses 178. The slide groove 176 of the first cover plate 142 cooperates with the boss 178 of the third cover plate 144 to allow the first cover plate 142 and the third cover plate 144 to slide relative to each other, the slide groove 176 of the third cover plate 144 cooperates with the boss 178 of the fourth cover plate 146 to allow the third cover plate 144 and the fourth cover plate 146 to slide relative to each other, and the slide groove 176 of the fourth cover plate 146 cooperates with the boss 178 of the second cover plate 148 to allow the fourth cover plate 146 and the second cover plate 148 to slide relative to each other. Preferably, the protrusion 178 is used to form the sliding slot 176, so that the structure of the cover plate 140 is simplified and the manufacturing efficiency is high. The projection 178 may protrude inward toward the cover plate 140 or outward toward the cover plate 140, and accordingly, when the projection 178 protrudes inward toward the cover plate 140, the sliding groove 176 faces outward toward the cover plate 140; when the projection 178 projects outward of the cover plate 140, the slide groove 176 is directed inward of the cover plate 140. The bottom cover assembly 114 may be made of metal or plastic.

Referring again to fig. 5, the flexible display device 100 includes a roller 180 disposed in the housing 104, and one end of the flexible display screen 102 is connected to the roller 180. In this way, the flexible display device 100 can be kept compact by using the winding drum 180 to wind the flexible display screen 102.

Specifically, for automation, a button 182 is disposed on an outer surface of the housing 104, a motor (not shown) is disposed in the winding drum 180, the button 182 is connected to the motor, and the motor rotates to drive the winding drum 180 to rotate. The keys 182 may facilitate the user to operate the flexible display device 100 to toggle between the extended state and the retracted state.

It is understood that the support structure 106 is capable of telescoping the flexible display screen 102 relative to the housing 104 to switch back and forth between the deployed state and the retracted state. When the flexible display screen 102 is in the retracted state, the rear cover 116 can be manually pulled to extend the lower cover assembly 114 and the slide rail assembly 108. Since the supporting plate 118 is fixed to the flexible display screen 102 by adhesion, the supporting plate 118 is fixed to the sliding rail assembly 108 by the fixing member 120 (magnetic member), and the supporting structure 106 can drive the flexible display screen 102 to extend relative to the housing 104. When the flexible display screen 102 is in the unfolded state, the button 182 controls the motor to rotate to drive the roller 180 to rotate, so that the flexible display screen 102 is rolled relative to the housing 104. It should be noted that, the fixing member 120 is disposed on the sliding rail hinge 126 of the sliding rail assembly 108 to attract the fixed support plate 118, a magnetic attraction force of the fixing member 120 on the sliding rail hinge 126 close to the housing 104 to the support plate 118 is smaller than a force of the motor to roll the flexible display screen 102, and a magnetic attraction force of the fixing member 120 on the sliding rail hinge 126 far away from the housing 104 to the support plate 118 is larger than a force of the motor to roll the flexible display screen 102. Thus, when the flexible display screen 102 is rolled, the sliding rail assembly 108 and the lower cover assembly 114 can be driven to shrink, and the supporting plate 118 can be ensured to be rolled along with the flexible display screen 102. Preferably, one end of the support plate 118 is fixed to one end of the first plurality of slide rail hinges 128, so that the support plate 118 is prevented from separating from the slide rail assembly 108 when the flexible display screen 102 is rolled, and the support structure 106 cannot be retracted along with the rolling of the flexible display screen 102.
