Furthermore, the terms "first," "second," and the like, are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
It should be noted that, in the case of no conflict, different features in the embodiments of the present application may be combined with each other.
Referring to fig. 1, the present embodiment provides a display apparatus including a flexible display panel 5, a support assembly 1, a roll assembly 2, a coil spring 6, a lifting assembly 3, and a locking assembly 4.
The reel assembly 2 is located on the support assembly 1 and extends along a first direction, the reel assembly 2 is connected with one end of the flexible display panel 5, and the reel assembly 2 is used for winding the flexible display panel 5.
The first direction may be an X-axis direction in a spatial coordinate system, and if an end of the flexible display panel 5 extending in the first direction and close to the reel assembly 2 is regarded as a first end, and an end of the flexible display panel 5 extending in the first direction and far from the reel assembly 2 is regarded as a second end, the first end is connected to the reel assembly 2.
The reel assembly 2 may rotate around its own axis, and when the reel assembly 2 rotates in one direction (e.g., rotates counterclockwise), the flexible display panel 5 may be wound around the reel assembly 2, i.e., the flexible display panel 5 may be wound, and when the reel assembly 2 rotates in the other direction (e.g., rotates clockwise), the flexible display panel 5 may be unwound from the reel assembly 2, i.e., the flexible display panel 5 may be unwound.
The lifting assembly 3 and the locking assembly 4 are positioned on the supporting assembly 1, one end of the lifting assembly 3 away from the supporting assembly 1 is connected with the other end (second end) of the flexible display panel 5, one end of the lifting assembly 3 away from the supporting assembly 1 extends out in a direction away from the supporting assembly 1 so as to unfold the flexible display panel 5, and the locking assembly 4 is used for locking the lifting assembly 3 so as to enable the flexible display panel 5 to be in an unfolded state.
The lifting assembly 3 and the locking assembly 4 are mounted on the supporting assembly 1, and one end of the lifting assembly 3 away from the supporting 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 supporting assembly 1 extends in a direction away from the supporting assembly 1, the end of the lifting assembly 3 away from the supporting assembly 1 drives the second end of the flexible display panel 5 to extend together. 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 is kept in an extended state after being locked, so that the flexible display panel 5 can be kept in an unfolded state.
The first elastic member is connected with the reel assembly 2 and is used for providing power for winding the flexible display panel 5. Wherein the first resilient member comprises a coil spring 6.
When the end of the lifting assembly 3 away from the supporting assembly 1 drives the second end of the flexible display panel 5 to extend together, the flexible display panel 5 drives the reel assembly 2 to rotate. Depending on the nature of the wrap spring 6 itself, the wrap spring 6 will accumulate the recoil force of the recoil as the reel assembly 2 rotates.
When the flexible display panel 5 needs to be rolled up, the locking assembly 4 is not locked with the lifting assembly 3. At this time, the flexible display panel 5 is no longer supported by the support component 1, and under the effect of the rewinding force of the coil spring 6, the coil spring 6 can drive the reel component 2 to rotate, and when the reel component 2 rotates, the flexible display panel 5 can be wound on the reel component 2. During the process of winding the flexible display panel 5 onto the reel assembly 2, the end of the lifting assembly 3 away from the supporting assembly 1 moves along with the flexible display panel 5 in the direction of the supporting assembly 1.
Based on the design, the flexible display panel 5 can be more conveniently unfolded by arranging the lifting assembly 3, and the flexible display panel 5 can be more conveniently rolled on the reel assembly 2 by arranging the coil spring 6 connected with the reel assembly 2, so that the flexible display panel 5 of the display device can be more conveniently unfolded and rolled.
In a possible implementation, referring to fig. 2, the support assembly 1 includes a beam 102, the lifting assembly 3 is disposed on the beam 102, a sliding assembly is disposed on the beam 102 along a first direction, the sliding assembly is connected with the lifting assembly 3 through a hinge, the sliding assembly is used for extending an end of the lifting assembly 3 away from the support assembly 1 toward a direction away from the support assembly 1 or for retracting an end of the lifting assembly 3 away from the support assembly 1 toward a direction close to the support assembly 1, and a displacement vector line of the sliding assembly is not collinear with a rotation axis of the hinge.
For example, when the sliding assembly moves in the first direction, the end of the lifting assembly 3 away from the supporting assembly 1 extends in a direction away from the supporting assembly 1 to expand the flexible display panel 5, and when the sliding assembly moves in a direction opposite to the first direction, the end of the lifting assembly 3 away from the supporting assembly 1 retracts in a direction close to the supporting assembly 1 to contract 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, thereby facilitating the unwinding or rewinding of the flexible display panel 5.
During the sliding of the sliding assembly, the hinge connected between the sliding assembly and the lifting assembly 3 will rotate, and the displacement vector line of the sliding assembly is not collinear with the rotation axis of the hinge. Thus, the sliding assembly is more conveniently arranged, so that the volume of the sliding assembly can be reduced, and the volume of the display device can be further reduced.
Preferably, referring again to fig. 2, the support assembly 1 further includes a first cover plate 101 and a second cover plate 103 disposed opposite to each other, the beam 102 is disposed between the first cover plate 101 and the second cover plate 103, and the locking assembly 4 is disposed on the beam 102. Referring to fig. 3, the sliding assembly includes a locking slide 13 and a locking slider 12 disposed on a beam 102 along a first direction, and the locking slide 13 is slidably connected to the locking slider 12. The beam 102 is arranged along the first direction, one end of the beam 102 is connected with the first cover plate 101, the other end is connected with the second cover plate 103, and the locking slide rail 13 can be fixed on the beam 102 through screws.
The lifting assembly 3 comprises at least one scissor fork type lifting structure, one lifting arm of the scissor fork type lifting structure, which is close to one end of the beam 102, is hinged with the beam 102 through a first rotating shaft 10, the other lifting arm of the scissor fork type lifting structure is hinged with the locking sliding block 12 through a hinge piece, one end of the scissor fork type lifting structure, which is far away from the beam 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 so as to lock the lifting assembly 3.
The hinge member includes a second rotation shaft 11, and the scissor lift structure includes a plurality of sets of lift arm groups, each set of lift arm groups includes two lift arms cross-hinged through a hinge shaft, and the number of sets of lift arm groups of the scissor lift structure, such as two sets of lift arm groups, can be selected according to the height of the flexible display panel 5 to be deployed.
The sliding groove can be formed in the locking sliding rail 13 along the first direction, the sliding edge matched with the sliding groove is arranged in the locking sliding block 12 along the first direction, and the sliding edge slides in the sliding groove, so that sliding connection between the locking sliding block 12 and the locking sliding rail 13 is realized.
When it is desired to deploy the flexible display panel 5, the user may either lift the end of the scissor lift structure remote from the beam 102 with an upward force or may push the end of the scissor lift structure remote from the beam 102 with an upward force via a power member, such as a cylinder.
When the end of the scissor type lifting structure far away from the beam 102 receives lifting force or pushing force, one lifting arm hinged with the beam 102 rotates around the first rotating shaft 10, and the other lifting arm hinged with the locking sliding block 12 rotates around the second rotating shaft 11 and drives the locking sliding block 12 to slide on the locking sliding rail 13 towards the direction of one lifting arm. When the locking slide block 12 slides, one end of the scissor-fork type lifting structure, which is far away from the beam 102, is lifted in a direction far away from the beam 102, so that the flexible display panel 5 can be unfolded. In this way, the scissor type lifting structure is used as a lifting mechanism for unfolding the flexible display panel 5, so that the flexible display panel 5 can be more conveniently unfolded, and the flexible display panel 5 can be better supported, and the problem of stress concentration during unfolding of the flexible display panel 5 can be reduced.
Preferably, referring again to fig. 2, a connection plate 7 is connected to one end of the scissor lift structure remote from the beam 102, the connection plate 7 being connected to the other (second) end of the flexible display panel 5. The connecting plate 7 is arranged along the first direction, and through the arrangement of the connecting plate 7, the other end of the flexible display panel 5 can be more conveniently connected, so that the flexible display panel 5 can be more conveniently unfolded and rolled up through lifting of the scissor type lifting structure.
Preferably, a force applying groove is also provided on the connection plate 7, and when the scissor lift structure is required to be lifted, a user can extend a finger into the force applying groove and apply an upward lifting force to the connection plate 7. In this way, by providing the force application groove, it is more convenient for the user to stretch the end of the scissor lift structure away from the beam 102 in a direction away from the beam 102.
Preferably, referring to fig. 4, the non-display side of the flexible display panel 5 is attached with a glue coating 14. When the flexible display panel 5 is rolled up, the glue coating layer 14 can be attached to the display surface of the flexible display panel 5, so that the display surface of the flexible display panel 5 can be protected by attaching the glue coating layer 14 to the non-display side surface of the flexible display panel 5, and the quality of the flexible display panel 5 can be improved.
When the flexible display panel 5 is unfolded, the encapsulation layer 14 can generate a certain pressure force against the front surface of the flexible display panel 5, and the encapsulation layer 14 can enable the flexible display panel 5 to be stretched more, so that a better visual experience can be brought about.
Preferably, referring to fig. 5, a housing 15 with a notch is connected between the first cover plate 101 and the second cover plate 103, and the flexible display panel 5 can extend from the notch to the outside of the housing 15, where the reel assembly 2 and the beam 102 are both located in the housing 15.
The notch is arranged along the first direction, and the lifting assembly 3 can drive the flexible display panel 5 to extend out of the notch. By providing the housing 15, components within the housing 15, such as the spool assembly 2 and the cross beam 102, may be protected and protected from dust.
In a possible implementation, referring again to fig. 2, an unlocking component 9 is further disposed on the beam 102, and an unlocking plate 8 is connected between the unlocking component 9 and the locking component 4, where the unlocking component 9 is used to move the unlocking plate 8 along a first direction, so that the locking component 4 unlocks the locking slider 12.
When the flexible display panel 5 needs to be rolled up, the unlocking plate 8 moves towards the locking slide block 12 through the unlocking component 9, and when the unlocking plate 8 moves towards the locking slide block 12, the locking component 4 can be unlocked, and the locking of the locking slide block 12 can be released after the locking component 4 is unlocked. When the locking assembly 4 releases the locking of the locking slider 12, the coil spring 6 winds the flexible display panel 5 around the reel assembly 2.
In one possible implementation, referring to fig. 6, the unlocking assembly 9 includes an unlocking slide rail 94, an unlocking slide 93, an unlocking seat 91, and an unlocking block 92.
The unlocking slide 94 is located on the beam 102 and is arranged in a first direction. The unlocking slide rail 94 may be mounted on the beam 102 by a screw, and the unlocking slide rail 94 may be provided with a slide groove along the first direction.
The unlocking slide block 93 is slidably connected with the unlocking slide rail 94 in the first direction, and the unlocking slide block 93 is connected with the unlocking plate 8. For example, the unlocking slide 93 and the unlocking plate 8 may be connected by a screw.
Referring to fig. 7, an unlocking groove 932 is formed at an end of the unlocking slide 93 away from the locking slide 12, and the unlocking groove 932 includes a first unlocking slope 931 inclined toward the locking slide 12. The unlocking slide block 93 may be provided with a sliding rib matched with the sliding groove, and the sliding rib is in sliding connection with the sliding groove, so as to realize sliding connection between the unlocking slide rail 94 and the unlocking slide block 93.
The unlocking seat 91 is located on the beam 102, referring to fig. 8, an unlocking through hole 911 is formed on the unlocking seat 91, and the unlocking seat 91 can be mounted on the beam 102 by a screw.
Referring to fig. 7 again, the unlocking block 92 passes through the unlocking through hole 911, and one end of the unlocking block 92, which is close to the unlocking slide block 93, is provided with a second unlocking inclined plane 921, and the second unlocking inclined plane 921 and the first unlocking inclined plane 931 are mutually attached. The inclination angles of the first unlocking inclined plane 931 and the second unlocking inclined plane 921 can be designed according to actual needs, and the unlocking through hole 911 is in clearance fit or transition fit with the unlocking block 92.
When the locking of the locking slide block 12 needs to be released, the user can press the unlocking block 92 in the direction of the unlocking slide block 93 (the Z-axis direction of the space coordinate), and when the unlocking block 92 moves, the first unlocking inclined plane 931 of the unlocking block 92 can press the second unlocking inclined plane 921 of the unlocking slide block 93. Since the first unlocking slope 931 is inclined toward the lock slider 12, the pressing force generates a pressing force component in the direction of the unlocking slider 93, and the unlocking slider 93 moves in the direction of the lock slider 12 after receiving the pressing force component. Since the unlocking slide 93 is connected to the unlocking plate 8, the unlocking slide 93 drives the unlocking plate 8 to slide together in the direction of the locking slide 12. When the unlocking plate 8 is moved into place, the locking assembly 4 can be triggered to unlock the locking slide 12. Thus, the unlocking block 92 is pressed to unlock the locking slide block 12, so that the operation is convenient, and the winding efficiency of the flexible display panel 5 can be greatly improved.
In one possible implementation, referring again to fig. 7, at least one reset slot 941 is further formed on the unlocking slide rail 94 along the first direction, and a reset member 16 is installed in the reset slot 941, where an end of the reset member 16 away from the locking slide 12 is connected to the unlocking slide 93, and the reset member 16 is used to provide a reset elastic force for the unlocking block 92.
The reset member 16 includes reset springs, the number of the reset grooves 941 can be designed according to the requirement, one reset spring is installed in one reset groove 941, and under the condition that the model of the reset spring is fixed, the more the reset springs, the larger the elastic force for providing reset for the unlocking block 92.
When the unlocking slide 93 drives the unlocking plate 8 to slide towards the locking slide 12, the reset element 16 is compressed. When the user no longer presses the unlocking block 92, the restoring member 16 returns to its original state, so that the restoring member 16 gives the unlocking slide 93 an elastic force in a direction away from the locking slide 12. Under the action of the elastic force, the unlocking slide 93 moves away from the locking slide 12, and pushes the unlocking block 92 away from the unlocking slide 93. Under the urging force, the unlocking block 92 moves away from the unlocking slider 93 and returns to the original position. In this way, by providing the reset member 16 connected with the unlocking slide 93, the unlocking block 92 can be more conveniently reset, thereby being more convenient for the user to use next time.
Preferably, referring to fig. 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 larger than that of the unlocking through hole 911. When the unlocking slider 93 drives the unlocking block 92 to move away from the unlocking slider 93, the unlocking block 92 may pop out of the unlocking through hole 911 to separate from the unlocking seat 91. Therefore, by providing the stopper ring 922 having a larger diameter than the unlocking through hole 911, the unlocking block 92 can be prevented from being separated from the unlocking seat 91 when being reset.
In one possible implementation, referring to FIG. 10, the locking assembly 4 includes a locking plate 402 and a locking tongue 401.
The locking plate 402 is located on the beam 102. Referring to fig. 11, a sliding hole 4021 is formed in the locking plate 402, the sliding hole 4021 is disposed along a direction from the unlocking plate 8 to the locking slider 12 (i.e., the sliding hole 4021 is disposed along a Y-axis direction in a space coordinate system), and the locking plate 402 may be mounted on the beam 102 by a screw.
The lock tongue 401 passes through the sliding hole 4021, referring to fig. 12, the lock tongue 401 includes a sliding portion 4013, a locking portion 4012, and a power portion 4011, and the sliding portion 4013, the locking portion 4012, and the power portion 4011 are sequentially integrally formed.
Referring again to fig. 10, the unlocking plate 8 is provided with a bar-shaped hole 82 extending obliquely toward the locking slide block 12, referring to fig. 13, the locking slide block 12 is provided with a locking hole 121 on a side close to the locking tongue 401, the sliding portion 4013 is slidably connected with the sliding hole 4021, the power portion 4011 passes through the bar-shaped hole 82, and when the locking portion 4012 is located in the locking hole 121, the locking tongue 401 locks the locking slide block 12.
The cross section of the sliding hole 4021 is a non-circular hole, for example, the cross section of the sliding hole 4021 may be polygonal, or may be a combination of a semicircle and a straight line, so that only sliding movement can be generated between the sliding portion 4013 of the lock tongue 401 and the sliding hole 4021, and no rotational movement can be generated.
One end of the locking part 4012, which is close to the locking slide block 12, is provided with an oblique cambered surface, when the end, which is far away from the cross beam 102, of the scissor type lifting structure ascends to the direction, which is far away from the cross beam 102, relative sliding is generated between the locking slide block 12 and the oblique cambered surface, and when the end, which is far away from the cross beam 102, of the scissor type lifting structure ascends to the top, the power part 4011 of the lock tongue 401 moves in the bar-shaped hole 82 towards the direction of the locking slide block 12, and finally the locking part 4012 of the lock tongue 401 is clamped into the locking hole 121 of the locking slide block 12 and locks the locking slide block 12. By providing the inclined arc surface at the end of the locking portion 4012 near the locking slider 12, the resistance between the locking slider 12 and the locking portion 4012 can be reduced, so that the locking portion 4012 is more easily caught in the locking hole 121 of the locking slider 12.
It should be noted that the power for locking the locking portion 4012 of the locking bolt 401 into the locking hole 121 of the locking slider 12 may be the elastic force transmitted to the unlocking plate 8 by the reset member 16 in the above embodiment, or a spring may be separately provided for the locking bolt 401, and the locking portion 4012 of the locking bolt 401 may be locked into the locking hole 121 of the locking slider 12 by the elastic force of the spring, or the locking portion 4012 of the locking bolt 401 may be pushed into the locking hole 121 of the locking slider 12 by a user.
When the unlocking plate 8 moves towards the locking slide block 12 through the unlocking block 92, the power portion 4011 of the lock tongue 401 passes through the bar-shaped hole 82, and the bar-shaped hole 82 obliquely extends towards the direction of the locking slide block 12, so that the power portion 4011 of the lock tongue 401 is driven to move towards a direction away from the locking slide block 12 in the moving process of the unlocking plate 8 towards the locking slide block 12, and finally the locking portion 4012 of the lock tongue 401 is pushed out from the locking hole 121, so that the locking of the locking slide block 12 is released. In this way, by providing the latch 401 and the locking hole 121 of the locking slider 12, locking and unlocking of the locking slider 12 can be more facilitated.
Preferably, the power unit 4011 is provided with a power bearing 403, and the power bearing 403 is connected with the bar-shaped hole 82 in a rolling manner. When the unlocking plate 8 pushes the power portion 4011 of the lock tongue 401, the power portion 4011 of the lock tongue 401 moves in the bar hole 82, and by installing the power bearing 403 on the power portion 4011 of the lock tongue 401, sliding friction between the power portion 4011 and the bar hole 82 can be converted into rolling friction, so that damping between the power portion 4011 and the bar hole 82 can be reduced, and locking of the locking slider 12 can be released more conveniently.
In one possible implementation, referring again to fig. 6, another locking assembly 4 includes a hanger bracket 41 and a swivel hanger 42.
The hook seat 41 is located on the beam 102, the hook seat 41 and the beam 102 are provided with arc-shaped through holes 411 corresponding to each other, and the hook seat 41 can be mounted on the beam 102 through screws.
The rotating hook 42 passes through the arc-shaped through hole 411, please refer to fig. 14, the rotating hook 42 comprises a rotating part 422 and a hook part 421, a power hole 81 is formed on the unlocking plate 8, the rotating part 422 passes through the arc-shaped through hole 411 and extends into the power hole 81, and please refer to fig. 15, the locking slide block 12 comprises a hook section 122, and when the hook section 122 and the hook part 421 are locked mutually, the rotating hook 42 locks the locking slide block 12.
When the scissor lift structure is lifted away from the end of the beam 102 in a direction away from the beam 102, the hook section 122 of the locking slider 12 pushes the rotating hook 42 to rotate, and when the scissor lift structure is lifted away from the end of the beam 102 to the highest position, the hook section 122 of the locking slider 12 passes over the hook portion 421 of the rotating hook 42, and the rotating hook 42 reversely rotates to lock the hook section 122 and the hook portion 421 with each other, so that the rotating hook 42 locks the locking slider 12.
When the unlocking plate 8 moves toward the locking slider 12, since the rotating portion 422 of the rotating hook 42 extends into the power hole 81, the unlocking plate 8 gives a rotating component force to the rotation of the rotating hook 42, and the rotating hook 42 rotates under the action of the rotating component force until the hook portion 421 of the rotating hook 42 is unhooked from the hook section 122 of the locking slider 12, thereby unlocking the locking slider 12. Thus, by providing a structure in which the rotating hook 42 and the locking slider 12 can be locked to and unlocked from each other, locking and unlocking of the locking slider 12 can be facilitated.
In a possible implementation, referring to fig. 16, the support assembly 1 is further provided with a second elastic member, where the second elastic member is used to provide an auxiliary pulling force or a blocking force for the lifting assembly 3, and the direction of the auxiliary pulling force is a direction in which an end of the lifting assembly 3 away from the support assembly extends away from the support assembly 1, and the direction of the blocking force is a direction in which an end of the lifting assembly 3 away from the support assembly 1 retracts toward the support assembly 1.
When the user applies a lifting force to the end of the lifting assembly 3 away from the supporting assembly 1 in a direction away from the supporting assembly 1, the second elastic member may apply an auxiliary pulling force to the user in the same direction as the lifting force, so that the user may more easily extend the lifting assembly 3. When the locking component 4 is unlocked, the flexible display panel 5 drives one end of the lifting component 3, which is far away from the supporting component 1, to move towards the direction close to the supporting component 1 under the resilience force of the coil spring 6, and at the moment, the second elastic piece can generate a blocking force opposite to the resilience force of the coil spring 6, and under the blocking force, the flexible display panel 5 can be slowly rolled up, so that the flexible display panel 5 can be protected.
Further, referring to fig. 16 again, the second elastic member includes a constant force spring 17, a protrusion 18 is further disposed on the beam 102, the constant force spring 17 is connected between the protrusion 18 and the locking slider 12, and the constant force spring 17 is used for providing an auxiliary pulling force or a blocking force to the locking slider 12, where the direction of the auxiliary pulling force is the sliding direction of the locking slider 12 toward the lifting arm, and the direction of the blocking force is the sliding direction of the locking slider 12 away from the lifting arm (i.e. the blocking force is opposite to the direction of the auxiliary pulling force).
One end of the constant force spring 17 is sleeved on the protrusion 18, and the other end of the constant force spring can be connected with the locking slide block 12 through a screw. From the characteristics of the constant force spring 17, it is known that the elastic force generated by the constant force spring 17 is constant. Referring to fig. 17, when a user applies a lifting force F1 in a direction away from the cross beam 102 to an end of the scissor lift structure away from the cross beam 102, a force spring component F2 generated by an auxiliary pulling force applied by the constant force spring 17 to the locking slider 12 is transferred to the end of the scissor lift structure away from the cross beam 102, the force spring component F2 is in the same direction as the lifting force F1, and a tangential component F3 of a return force generated by the coil spring 6 is opposite to the force spring component F2. From the force analysis in fig. 11, it is known that the user can expand the flexible display panel 5 with the aid of the force spring component force F2 generated by the constant force spring 17 with a small lifting force F1.
Referring to fig. 18, when the scissor lift structure is unlocked, the scissor lift structure receives only the force spring component F2 and the tangential component F3 generated by the coil spring 6 in opposite directions, and the tangential component F3 is larger by Yu Lihuang component F2. Thus, under the tangential force component F3 generated by the coil spring 6, one end of the scissor lift structure away from the beam 102 moves toward the beam 102, and the flexible display panel 5 is wound up by the reel assembly 2. Because of the force spring component force F2, the winding drum assembly 2 can wind the flexible display panel 5 more slowly, so that the flexible display panel 5 can be prevented from being damaged due to the fact that the force spring component force F2 is too large.
In one possible implementation, referring again to FIG. 6, the spool assembly 2 includes a spool side lock 201, a bearing housing 203, a spring seat 204, and a spool 205. The reel side lock 201 is mounted on the support assembly 1, the bearing block 203 is mounted on the reel side lock 201 through the reel bearing 202, the spring seat 204 is connected with the bearing block 203, the coil spring 6 is mounted in the spring seat 204 and connected with the spring seat 204, the reel 205 is connected with the spring seat 204, and one end of the flexible display panel 5 is connected with the reel 205.
The spring seat 204 and the bearing seat 203 can be connected through a locking strip, both ends of the scroll 205 are sequentially connected with the spring seat 204, the coil spring 6, the bearing seat 203, the spool bearing 202 and the spool side lock 201, wherein one spool side lock 201 can be connected with the first cover plate 101 through a screw, and the other spool side lock 201 can be connected with the second cover plate 103 through a screw.
When the coil spring 6 generates a rebound force, the reel 205 is driven to rotate, and the flexible display panel 5 can be wound on the reel 205 by the rotation of the reel 205, so that the winding of the flexible display panel 5 is completed. Thus, by installing the coil spring 6 between the spring seat 204 and the bearing housing 203, the spring seat 204, the bearing housing 203 and the spool 205 can be rotated together, so that it is possible to more easily install the coil spring 6 and to more easily rotate the spool 205 by the coil spring 6.
In a possible implementation, referring to fig. 19, the reel 205 includes a shaft cover 2052 and a shaft seat 2051 that are connected to each other, a transition plate 19 is installed in the reel 205 along a first direction, the transition plate 19 includes 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 installed in the reel 205, and the flexible display panel 5 is attached to the transition arc surface 191 and passes through the gap 20.
Providing the scroll 205 to include the shaft cover 2052 and the shaft seat 2051 that can be separated from each other may further facilitate the provision of the transition plate 19 within the scroll 205 and may further facilitate the fixation of one end of the flexible display panel 5 within the scroll 205. There is also provided a space and support around which the flexible display panel 5 is curled from inside to outside, a battery, a control board, etc. can be provided inside the reel 205, and the internal space of the reel 205 is maximally utilized. The gap 20 corresponds to a notch on the housing 15 in the above embodiment, and the flexible display panel 5 may protrude from the gap 20.
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 scroll 205, so that the components can be protected. The transition plate 19 may support the flexible display panel 5 from the inside of the roller 205 to the gap 20, and the side surface of the flexible display panel 5 may be attached to the transition arc surface 191, so that the stress of the flexible display panel 5 may be reduced, and the flexible display panel 5 may be protected.
Preferably, the curvature of the transition curve 191 increases gradually in a direction from within the spool 205 to the gap 20. In this way, a better transition effect can be achieved for the flexible display panel 5, so that the flexible display panel 5 can be further better protected.
Preferably, the transition curve 191 is at least partially tangential to the shaft seat 2051. Therefore, the flexible display panel 5 can be more easily transited to the shaft seat 2051, so that the stress of the flexible display panel 5 can be further reduced, and the flexible display panel 5 is better protected.
