In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0071] It should be noted that the different features in the embodiments of the application can be combined with each other without conflict.

[0072] Please refer to Figure 1 The embodiment provides a display device, which comprises a flexible display panel 5, a support assembly 1, a winding drum assembly 2, a winding spring 6, a lifting assembly 3 and a locking assembly 4.

[0073] The winding drum assembly 2 is located on the support assembly 1 and extends in a first direction, the winding drum assembly 2 is connected with one end of the flexible display panel 5, and the winding drum assembly 2 is used for winding the flexible display panel 5.

[0074] The first direction can be the X-axis direction in a spatial coordinate system, if one end of the flexible display panel 5 extending in the first direction and close to the winding drum assembly 2 is regarded as a first end, and the other end of the flexible display panel 5 extending in the first direction and away from the winding drum assembly 2 is regarded as a second end, then the first end is connected with the winding drum assembly 2.

[0075] The winding drum assembly 2 can rotate around its own axis, when the winding drum assembly 2 rotates in one direction (such as counterclockwise), the flexible display panel 5 can be wound on the winding drum assembly 2, that is, the flexible display panel 5 is wound; when the winding drum assembly 2 rotates in the other direction (such as clockwise), the flexible display panel 5 can be stretched from the winding drum assembly 2, that is, the flexible display panel 5 is unfolded.

[0076] The lifting assembly 3 and the locking assembly 4 are located on the support assembly 1, and an end of the lifting assembly 3 away from the support assembly 1 is connected with the other end (second end) of the flexible display panel 5, and the end of the lifting assembly 3 away from the support assembly 1 extends away from the support assembly 1 to unfold the flexible display panel 5; the locking assembly 4 is used to lock the lifting assembly 3 so that the flexible display panel 5 is in an unfolded state.

[0077] The lifting assembly 3 and the locking assembly 4 are installed on the support assembly 1, and an end of the lifting assembly 3 away from the support assembly 1 is connected with the second end of the flexible display panel 5. When the end of the lifting assembly 3 away from the support assembly 1 extends away from the support assembly 1, the end of the lifting assembly 3 away from the support assembly 1 drives the second end of the flexible display panel 5 to extend. When the lifting assembly 3 is lifted to a certain height, the lifting assembly 3 is locked by the locking assembly 4, and the lifting assembly 3 remains in the extended state after being locked, so that the flexible display panel 5 can be kept in an unfolded state.

[0078] The first elastic member is connected with the winding drum assembly 2, and is used to provide power for winding the flexible display panel 5. The first elastic member includes a winding spring 6.

[0079] When the end of the lifting assembly 3 away from the support assembly 1 drives the second end of the flexible display panel 5 to extend, the flexible display panel 5 drives the winding drum assembly 2 to rotate. According to the characteristics of the winding spring 6, when the winding drum assembly 2 rotates, the winding spring 6 accumulates a winding force for winding.

[0080] When it is necessary to wind the flexible display panel 5, the locking assembly 4 no longer locks the lifting assembly 3. At this time, the flexible display panel 5 is no longer supported by the support assembly 1, and under the action of the winding force of the winding spring 6, the winding spring 6 drives the winding drum assembly 2 to rotate, and when the winding drum assembly 2 rotates, the flexible display panel 5 can be wound onto the winding drum assembly 2. In the process of winding the flexible display panel 5 onto the winding drum assembly 2, the end of the lifting assembly 3 away from the support assembly 1 moves towards the support assembly 1 together with the flexible display panel 5.

[0081] Based on the above design, the flexible display panel 5 can be unfolded more conveniently by arranging the lifting assembly 3, and the flexible display panel 5 can be wound onto the winding drum assembly 2 more conveniently by arranging the winding spring 6 connected with the winding drum assembly 2, so that the flexible display panel 5 of the display device can be unfolded and wound more conveniently.

[0082] In a possible implementation, please refer to Figure 2, the support assembly 1 comprises a crossbeam 102, the lifting assembly 3 is arranged on the crossbeam 102, the crossbeam 102 is provided with a sliding assembly in the first direction, the sliding assembly and the lifting assembly 3 are connected through a hinge, the sliding assembly is used for extending the end of the lifting assembly 3 away from the support assembly 1 in the direction away from the support assembly 1 or is used for retracting the end of the lifting assembly 3 away from the support assembly 1 in the direction close to the support assembly 1, and the displacement vector line of the sliding assembly is not collinear with the rotation axis of the hinge.

[0083] For example, when the sliding assembly moves in the first direction, the end of the lifting assembly 3 away from the support assembly 1 extends in the direction away from the support assembly 1, so as to unfold the flexible display panel 5; when the sliding assembly moves in the opposite direction of the first direction, the end of the lifting assembly 3 away from the support assembly 1 retracts in the direction close to the support assembly 1, so as to roll up the flexible display panel 5. In this way, the movement of the sliding assembly along the X-axis direction in the space coordinate system can be converted into the movement of the lifting assembly 3 along the Z-axis direction in the space coordinate system, so that the flexible display panel 5 is more convenient to unfold or roll up.

[0084] In the process of sliding of the sliding assembly, the hinge connected between the sliding assembly and the lifting assembly 3 rotates, and the displacement vector line of the sliding assembly is not collinear with the rotation axis of the hinge. In this way, the sliding assembly is more convenient to layout, so that the volume of the sliding assembly can be reduced, and then the volume of the display device can be reduced.

[0085] Preferably, referring again to Figure 2 The support assembly 1 further comprises a first cover plate 101 and a second cover plate 103 arranged oppositely, the crossbeam 102 is arranged between the first cover plate 101 and the second cover plate 103, and the locking assembly 4 is arranged on the crossbeam 102. Referring to Figure 3 The sliding assembly comprises a locking sliding rail 13 and a locking sliding block 12 arranged on the crossbeam 102 in the first direction, and the locking sliding rail 13 and the locking sliding block 12 are connected in sliding mode. The crossbeam 102 is arranged in the first direction, one end of the crossbeam 102 is connected with the first cover plate 101, the other end is connected with the second cover plate 103, and the locking sliding rail 13 can be fixed on the crossbeam 102 through a screw.

[0086] The lifting assembly 3 comprises at least one scissor lifting structure, one lifting arm of the scissor lifting structure close to one end of the crossbeam 102 is hinged with the crossbeam 102 through a first rotating shaft 10, the other lifting arm is hinged with the locking sliding block 12 through a hinge, one end of the scissor lifting structure away from the crossbeam 102 is connected with the other end of the flexible display panel 5, and the locking assembly 4 is used for locking the locking sliding block 12 to lock the lifting assembly 3.

[0087] The hinge includes a second rotating shaft 11, and the scissor lifting structure includes a plurality of lifting arm groups, each of which includes two lifting arms cross-connected by a hinge shaft. The number of the lifting arm groups of the scissor lifting structure can be selected according to the height of the flexible display panel 5 to be unfolded, for example, two lifting arm groups are selected.

[0088] A sliding groove can be formed on the locking sliding rail 13 in the first direction, and a sliding ridge matching the sliding groove can be arranged on the locking sliding block 12 in the first direction. The sliding ridge slides in the sliding groove to realize the sliding connection between the locking sliding block 12 and the locking sliding rail 13.

[0089] When it is needed to unfold the flexible display panel 5, the user can give an upward lifting force to the end of the scissor lifting structure away from the cross beam 102, or a power element such as a cylinder can give an upward pushing force to the end of the scissor lifting structure away from the cross beam 102.

[0090] When the end of the scissor lifting structure away from the cross beam 102 is subjected to the upward lifting force or the pushing force, one of the lifting arms hinged to the cross beam 102 rotates around the first rotating shaft 10, and the other lifting arm hinged to the locking sliding block 12 rotates around the second rotating shaft 11, while driving the locking sliding block 12 to slide on the locking sliding rail 13 in the direction of the lifting arm. During the sliding of the locking sliding block 12, the end of the scissor lifting structure away from the cross beam 102 rises in the direction away from the cross beam 102, i.e. the flexible display panel 5 is unfolded. In this way, by using the scissor lifting structure as the lifting mechanism for unfolding the flexible display panel 5, the flexible display panel 5 can be more conveniently unfolded, and the flexible display panel 5 can be better supported, so that the problem of stress concentration when the flexible display panel 5 is unfolded can be reduced.

[0091] Preferably, referring again to Figure 2 , the end of the scissor lifting structure away from the cross beam 102 is connected with a connecting plate 7, and the connecting plate 7 is connected with the other end (second end) of the flexible display panel 5. The connecting plate 7 is arranged in the first direction. By arranging the connecting plate 7, the other end of the flexible display panel 5 can be more conveniently connected, so that the unfolding and winding of the flexible display panel 5 by the lifting of the scissor lifting structure can be more conveniently realized.

[0092] Preferably, a force applying groove can be arranged on the connecting plate 7. When it is needed to lift the scissor lifting structure, the user can put his fingers into the force applying groove and apply an upward lifting force to the connecting plate 7. In this way, by arranging the force applying groove, the user can more conveniently stretch the end of the scissor lifting structure away from the cross beam 102 in the direction away from the cross beam 102.

[0093] Preferably, referring to Figure 4The non-display side of the flexible display panel 5 is attached with the encapsulation layer 14. When the flexible display panel 5 is rolled up, the encapsulation layer 14 can be attached with the display side of the flexible display panel 5, and thus the display side of the flexible display panel 5 can be protected by attaching the encapsulation layer 14 on the non-display side of the flexible display panel 5, so that the quality of the flexible display panel 5 can be improved.

[0094] When the flexible display panel 5 is unfolded, the encapsulation layer 14 can generate a certain pressure against the front side of the flexible display panel 5, and the encapsulation layer 14 can make the flexible display panel 5 more relaxed, so that a better visual experience can be brought.

[0095] Preferably, referring to Figure 5 The first cover plate 101 and the second cover plate 103 are connected with the shell 15 with a notch, the flexible display panel 5 can extend out of the shell 15 from the notch, and the winding drum assembly 2 and the cross beam 102 are located in the shell 15.

[0096] The notch is arranged in the first direction, and the lifting assembly 3 can drive the flexible display panel 5 to extend out of the notch. By arranging the shell 15, the components in the shell 15, such as the winding drum assembly 2 and the cross beam 102, can be protected and dustproof.

[0097] In a possible implementation, referring again to Figure 2 The cross beam 102 is further provided with the unlocking assembly 9, the unlocking assembly 9 is connected with the unlocking plate 8 between the unlocking assembly 9 and the locking assembly 4, and the unlocking assembly 9 is used to move the unlocking plate 8 in the first direction to make the locking assembly 4 unlock the locking block 12.

[0098] When it is needed to roll up the flexible display panel 5, the unlocking plate 8 is moved in the direction of the locking block 12 by the unlocking assembly 9, and when the unlocking plate 8 is moved in the direction of the locking block 12, the locking assembly 4 can be unlocked, and after the locking assembly 4 is unlocked, the locking of the locking block 12 can be released. When the locking assembly 4 releases the locking of the locking block 12, the winding spring 6 rolls up the flexible display panel 5 on the winding drum assembly 2.

[0099] In a possible implementation, referring to Figure 6 The unlocking assembly 9 includes the unlocking sliding rail 94, the unlocking sliding block 93, the unlocking seat 91 and the unlocking block 92.

[0100] The unlocking sliding rail 94 is located on the cross beam 102 and arranged in the first direction. The unlocking sliding rail 94 can be installed on the cross beam 102 by screws, and a sliding groove can be arranged on the unlocking sliding rail 94 in the first direction.

[0101] The unlocking sliding block 93 is slidably connected with the unlocking sliding rail 94 in the first direction, and the unlocking sliding block 93 is connected with the unlocking plate 8. For example, the unlocking sliding block 93 and the unlocking plate 8 can be connected by screws.

[0102] Please see Figure 7 , the end of the unlocking slider 93 away from the locking slider 12 is provided with an unlocking slot 932, and the unlocking slot 932 includes a first unlocking slope 931 inclined to the side of the locking slider 12. The unlocking slider 93 can be provided with a sliding ridge matched with the sliding groove, and the sliding ridge is in sliding connection with the sliding groove to realize the sliding connection between the unlocking sliding rail 94 and the unlocking slider 93.

[0103] The unlocking seat 91 is located on the cross beam 102, please see Figure 8 , the unlocking seat 91 is provided with an unlocking through hole 911, and the unlocking seat 91 can be installed on the cross beam 102 by screws.

[0104] Please see again Figure 7 , the unlocking block 92 passes through the unlocking through hole 911, and the end of the unlocking block 92 close to the unlocking slider 93 is provided with a second unlocking slope 921, and the second unlocking slope 921 is matched with the first unlocking slope 931. The inclination angles of the first unlocking slope 931 and the second unlocking slope 921 can be designed according to actual needs, and the unlocking through hole 911 and the unlocking block 92 are in clearance fit or transition fit.

[0105] When it is needed to release the locking of the locking slider 12, the user can press the unlocking block 92 to the direction of the unlocking slider 93 (the Z-axis direction of the spatial coordinates), and when the unlocking block 92 moves, the first unlocking slope 931 of the unlocking block 92 will press the second unlocking slope 921 of the unlocking slider 93. Because the first unlocking slope 931 is inclined to the side of the locking slider 12, the pressing force will generate a pressing component force in the direction of the unlocking slider 93, and the unlocking slider 93 will move to the direction of the locking slider 12 after receiving the pressing component force. Because the unlocking slider 93 is connected with the unlocking plate 8, the unlocking slider 93 will drive the unlocking plate 8 to slide to the direction of the locking slider 12. When the unlocking plate 8 moves to the appropriate position, the locking assembly 4 can be triggered to release the locking of the locking slider 12. In this way, the locking of the locking slider 12 can be released by pressing the unlocking block 92, the operation is relatively convenient, and the rolling efficiency of the flexible display panel 5 can be greatly improved.

[0106] In a possible implementation, please see again Figure 7 , the unlocking sliding rail 94 is further provided with at least one reset slot 941 in the first direction, and a reset member 16 is installed in the reset slot 941. The end of the reset member 16 away from the locking slider 12 is connected with the unlocking slider 93, and the reset member 16 is used to provide the reset elastic force for the unlocking block 92.

[0107] The reset member 16 includes reset springs, and the number of reset slots 941 can be designed as required, one reset spring is installed in one reset slot 941, and in the case of a certain type of reset spring, the more reset springs, the greater the elastic force provided for the reset of the unlocking block 92.

[0108] When the unlocking slider 93 drives the unlocking plate 8 to slide towards the locking slider 12, the reset member 16 is compressed. When the user no longer presses the unlocking block 92, the reset member 16 returns to its original state, so that the reset member 16 provides the unlocking slider 93 with an elastic force in the direction away from the locking slider 12. Under the action of the elastic force, the unlocking slider 93 moves in the direction away from the locking slider 12, and provides the unlocking block 92 with a pushing force in the direction away from the unlocking slider 93. Under the action of the pushing force, the unlocking block 92 moves in the direction away from the unlocking slider 93 and returns to the original position. In this way, by arranging the reset member 16 connected with the unlocking slider 93, the reset of the unlocking block 92 is more convenient, thereby facilitating the user to use next time.

[0109] Preferably, referring to Figure 9 , the unlocking block 92 is provided with a limiting ring 922, the limiting ring 922 is located in the unlocking seat 91, and the diameter of the limiting ring 922 is greater than the diameter of the unlocking through hole 911. When the unlocking slider 93 drives the unlocking block 92 to move in the direction away from the unlocking slider 93, the unlocking block 92 may be ejected from the unlocking through hole 911 and separated from the unlocking seat 91. Therefore, by arranging the limiting ring 922 with a diameter greater than that of the unlocking through hole 911, the unlocking block 92 can be prevented from separating from the unlocking seat 91 during reset.

[0110] In a possible implementation, referring to Figure 10 , the locking assembly 4 includes a locking plate 402 and a lock tongue 401.

[0111] The locking plate 402 is located on the cross beam 102, referring to Figure 11 , the locking plate 402 is provided with a sliding hole 4021, the sliding hole 4021 is arranged in the direction from the unlocking plate 8 to the locking slider 12 (i.e. the sliding hole 4021 is arranged in the Y-axis direction of the spatial coordinate system), and the locking plate 402 can be installed on the cross beam 102 by screws.

[0112] The lock tongue 401 passes through the sliding hole 4021, referring to Figure 12 , the lock tongue 401 includes a sliding part 4013, a locking part 4012 and a power part 4011; the sliding part 4013, the locking part 4012 and the power part 4011 are integrally formed in sequence.

[0113] Please refer to Figure 10 , the unlocking plate 8 is provided with a strip-shaped hole 82 extending obliquely towards the locking slider 12, referring to Figure 13The locking hole 121 is formed on one side of the locking slider 12 close to the lock tongue 401, the sliding part 4013 is in sliding connection with the sliding hole 4021, and the power part 4011 passes through the strip-shaped hole 82; when the locking part 4012 is located in the locking hole 121, the lock tongue 401 locks the locking slider 12.

[0114] The cross section of the sliding hole 4021 is a non-circular hole, for example, the cross section of the sliding hole 4021 can be a polygon, and can also be a combination of a semicircle and a straight line, so that only sliding motion is generated between the sliding part 4013 of the lock tongue 401 and the sliding hole 4021, and no rotating motion is generated.

[0115] The locking part 4012 is provided with an inclined arc surface close to one end of the locking slider 12, when the scissor type lifting structure away from one end of the cross beam 102 is lifted in the direction away from the cross beam 102, the relative sliding is generated between the locking slider 12 and the inclined arc surface, when the scissor type lifting structure away from one end of the cross beam 102 is lifted to the top, the power part 4011 of the lock tongue 401 moves in the strip-shaped hole 82 to the direction of the locking slider 12, and finally the locking part 4012 of the lock tongue 401 is clamped into the locking hole 121 of the locking slider 12 and locks the locking slider 12. By providing the inclined arc surface close to one end of the locking slider 12 of the locking part 4012, the resistance between the locking slider 12 and the locking part 4012 can be reduced, so that the locking part 4012 is more easily clamped into the locking hole 121 of the locking slider 12.

[0116] It is worth noting that the power for clamping the locking part 4012 of the lock tongue 401 into the locking hole 121 of the locking slider 12 can be the elastic force transmitted by the reset member 16 to the unlocking plate 8 in the above-mentioned embodiment, a spring can also be separately provided for the lock tongue 401, the elastic force of the spring is used to clamp the locking part 4012 of the lock tongue 401 into the locking hole 121 of the locking slider 12, and the user can also push the locking part 4012 of the lock tongue 401 into the locking hole 121 of the locking slider 12.

[0117] When the unlocking plate 8 is moved to the locking slider 12 by the unlocking block 92, since the power part 4011 of the lock tongue 401 passes through the strip-shaped hole 82 and the strip-shaped hole 82 extends obliquely to the locking slider 12, during the movement of the unlocking plate 8 to the locking slider 12, the power part 4011 of the lock tongue 401 is moved to the direction away from the locking slider 12, and finally the locking part 4012 of the lock tongue 401 is pushed out of the locking hole 121, so as to release the locking of the locking slider 12. In this way, by providing the lock tongue 401 and the locking hole 121 of the locking slider 12, the locking and unlocking of the locking slider 12 can be more convenient.

[0118] Preferably, a power bearing 403 is installed on the power part 4011, and the power bearing 403 is in rolling connection with the strip-shaped hole 82. When the unlocking plate 8 pushes the power part 4011 of the lock tongue 401, the power part 4011 of the lock tongue 401 moves in the strip-shaped hole 82. By installing the power bearing 403 on the power part 4011 of the lock tongue 401, the sliding friction between the power part 4011 and the strip-shaped hole 82 can be converted into rolling friction, so that the damping between the power part 4011 and the strip-shaped hole 82 can be reduced, and the locking of the locking slide 12 can be more easily released.

[0119] In a possible implementation, referring again to Figure 6 , another locking assembly 4 comprises a hook seat 41 and a rotating hook 42.

[0120] The hook seat 41 is located on the cross beam 102, and the hook seat 41 and the cross beam 102 are both provided with corresponding arc-shaped through holes 411. The hook seat 41 can be installed on the cross beam 102 by screws.

[0121] The rotating hook 42 passes through the arc-shaped through hole 411. Referring to Figure 14 , the rotating hook 42 comprises a rotating part 422 and a hook part 421. The unlocking plate 8 is provided with a power hole 81. The rotating part 422 passes through the arc-shaped through hole 411 and extends into the power hole 81. Referring to Figure 15 , the locking slide 12 comprises a hook section 122. When the hook section 122 and the hook part 421 are locked with each other, the rotating hook 42 locks the locking slide 12.

[0122] When the scissor lifting structure away from one end of the cross beam 102 rises in the direction away from the cross beam 102, the hook section 122 of the locking slide 12 pushes the rotating hook 42 to rotate. When the scissor lifting structure away from one end of the cross beam 102 rises to the highest position, the hook section 122 of the locking slide 12 will pass over the hook part 421 of the rotating hook 42. The rotating hook 42 reversely rotates to make the hook section 122 and the hook part 421 locked with each other, so that the rotating hook 42 locks the locking slide 12.

[0123] When the unlocking plate 8 moves to the locking slide 12, because the rotating part 422 of the rotating hook 42 extends into the power hole 81, the unlocking plate 8 gives the rotating hook 42 a rotating component force. The rotating hook 42 rotates under the action of the rotating component force until the hook part 421 of the rotating hook 42 and the hook section 122 of the locking slide 12 are unhooked, so that the locking of the locking slide 12 is released. In this way, by setting the structure that the rotating hook 42 and the locking slide 12 can be locked and unhooked with each other, the locking and unlocking of the locking slide 12 can be more convenient.

[0124] In a possible implementation, referring to Figure 16The second elastic member is arranged on the support assembly 1 and used to provide an auxiliary pulling force or a blocking force for the lifting assembly 3, the auxiliary pulling force is in a direction that the end of the lifting assembly 3 away from the support assembly 1 extends away from the support assembly 1, and the blocking force is in a direction that the end of the lifting assembly 3 away from the support assembly 1 retracts towards the support assembly 1.

[0125] When the user applies a lifting force in a direction away from the support assembly 1 to the end of the lifting assembly 3 away from the support assembly 1, the second elastic member can apply an auxiliary pulling force in the same direction as the lifting force to the user, so that the user can more easily extend the lifting assembly 3. When the locking assembly 4 is unlocked, the flexible display panel 5 drives the end of the lifting assembly 3 away from the support assembly 1 to move towards the support assembly 1 under the resilience of the coil spring 6, at this time, the second elastic member generates a blocking force opposite to the direction of the resilience of the coil spring 6, and under the blocking force, the flexible display panel 5 is slowly wound, thereby playing a protective role on the flexible display panel 5.

[0126] Further, please refer again to Figure 16 The second elastic member includes a constant force spring 17, the cross beam 102 is further provided with a protrusion 18, and the constant force spring 17 is connected between the protrusion 18 and the locking slider 12. The constant force spring 17 is used to provide an auxiliary pulling force or a blocking force for the locking slider 12, the auxiliary pulling force is in a direction that the locking slider 12 slides towards the lifting arm, and the blocking force is in a direction that the locking slider 12 slides away from the lifting arm (i.e. the direction of the blocking force is opposite to that of the auxiliary pulling force).

[0127] One end of the constant force spring 17 is sleeved on the protrusion 18, and the other end can be connected with the locking slider 12 by a screw. According to the characteristics of the constant force spring 17, it can be known that the resilience generated by the constant force spring 17 is constant. Please refer to Figure 17 When the user applies a lifting force F1 in a direction away from the cross beam 102 to the end of the scissor lifting structure away from the cross beam 102, the force spring component F2 of the auxiliary pulling force applied by the constant force spring 17 on the locking slider 12 is transmitted to the end of the scissor lifting structure away from the cross beam 102, and the force spring component F2 is in the same direction as the lifting force F1, and the tangential component F3 of the resilience generated by the coil spring 6 is opposite to the direction of the force spring component F2. According to the force analysis in Figure 11 , it can be known that under the assistance of the force spring component F2 generated by the constant force spring 17, the user only needs to spend a small lifting force F1 to unfold the flexible display panel 5.

[0128] Please refer to Figure 18When the scissor lifting structure is unlocked, the scissor lifting structure is only subjected to the tangential component F3 generated by the force spring component F2 and the spring 6 in the opposite direction, and the tangential component F3 is greater than the force spring component F2. Therefore, under the action of the tangential component F3 generated by the spring 6, the scissor lifting structure moves towards the cross beam 102 from one end of the cross beam 102, and the flexible display panel 5 is wound by the winding drum assembly 2. Because of the existence of the force spring component F2, the winding drum assembly 2 will wind the flexible display panel 5 more slowly, so as to avoid damaging the flexible display panel 5 due to the excessive force spring component F2.

[0129] In a possible implementation, referring again to Figure 6 , the winding drum assembly 2 comprises a winding drum side lock 201, a bearing seat 203, a spring seat 204 and a winding shaft 205. The winding drum side lock 201 is mounted on the support assembly 1; the bearing seat 203 is mounted on the winding drum side lock 201 through a winding drum bearing 202; the spring seat 204 is connected with the bearing seat 203, the spring 6 is mounted in the spring seat 204 and connected with the spring seat 204; the winding shaft 205 is connected with the spring seat 204, and one end of the flexible display panel 5 is connected with the winding shaft 205.

[0130] The spring seat 204 and the bearing seat 203 can be connected through a locking strip, and the two ends of the winding shaft 205 are sequentially connected with the spring seat 204, the spring 6, the bearing seat 203, the winding drum bearing 202 and the winding drum side lock 201. One of the winding drum side locks 201 can be connected with the first cover plate 101 through a screw, and the other winding drum side lock 201 can be connected with the second cover plate 103 through a screw.

[0131] When the spring 6 generates a rebound force, the winding shaft 205 is driven to rotate, and the winding shaft 205 rotates to wind the flexible display panel 5 on the winding shaft 205, so as to complete the winding of the flexible display panel 5. In this way, by mounting the spring 6 between the spring seat 204 and the bearing seat 203, the spring seat 204, the bearing seat 203 and the winding shaft 205 can rotate together, so that the spring 6 can be more conveniently installed, and the winding shaft 205 can be more conveniently driven to rotate by the spring 6.

[0132] In a possible implementation, referring to Figure 19 , the winding shaft 205 comprises a shaft cover 2052 and a shaft seat 2051 connected with each other, the winding shaft 205 is mounted with a transition plate 19 in a first direction, the transition plate 19 comprises a transition arc surface 191, a gap 20 is left between the transition arc surface 191 and the shaft cover 2052, one end of the flexible display panel 5 is mounted in the winding shaft 205, and the flexible display panel 5 is attached to the transition arc surface 191 and passes through the gap 20.

[0133] The reel 205 is provided with a shaft cover 2052 and a shaft seat 2051 which can be separated from each other, so that the transition plate 19 can be conveniently arranged in the reel 205, and one end of the flexible display panel 5 can be conveniently fixed in the reel 205. The flexible display panel 5 is curled around from inside to outside, and the space and support are provided, the battery and the control board can be arranged in the reel 205, and the internal space of the reel 205 is maximally utilized. The gap 20 corresponds to the notch on the shell 15 in the above embodiment, and the flexible display panel 5 can be extended from the gap 20.

[0134] The components are arranged at one end of the flexible display panel 5, and the components at one end of the flexible display panel 5 are arranged in the reel 205, so that the components are protected. The transition plate 19 can support the flexible display panel 5 from the reel 205 to the gap 20, and the side surface of the flexible display panel 5 can be attached to the transition arc surface 191, so that the stress of the flexible display panel 5 is reduced, and the flexible display panel 5 is protected.

[0135] Preferably, the curvature of the transition arc surface 191 gradually increases along the direction from the reel 205 to the gap 20. In this way, the flexible display panel 5 is better transitioned, so that the flexible display panel 5 is further protected.

[0136] Preferably, the transition arc surface 191 is at least partially tangent to the shaft seat 2051. In this way, the flexible display panel 5 can be more easily transitioned to the shaft seat 2051, the stress of the flexible display panel 5 can be further reduced, and the flexible display panel 5 is better protected.

[0137] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the description.

[0138] The above embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
