The suspension display screen can break away from the installation carrier to make the display screen suspend in the air, make the display screen can use under some circumstances that are difficult to set up the installation carrier, make the display screen more pleasing to the eye moreover. In the related art, a magnetic suspension mode is generally adopted to realize suspension of the display screen, namely, the display screen is suspended by magnetic force. However, the magnetic levitation display screen is difficult to realize flexible deformation of the display screen, and particularly when the display screen is a flexible display screen, the flexible display screen is difficult to be curled, folded or stretched and unfolded.
The applicant has found that when the display is in a suspended state, the display is not normally subjected to other significant external forces than the magnetic force and therefore if the flexible display is to be rolled in or out, the application of external forces is required to roll in or out the flexible display panel. However, as the flexible display screen is in a suspended state, once an external force is applied, the stress balance of the suspended state is destroyed, so that the flexible display screen is separated from the suspended state.
In view of the above, the applicant has proposed a floating and stretching display device in which a first magnetic portion and a second magnetic portion are provided on a chassis, a flexible display panel is wound between a first shaft and a second shaft, a third magnetic portion is provided on the first shaft, and a fourth magnetic portion is provided on the second shaft. The first shaft is levitated by a magnetic force between the first magnetic part and the third magnetic part, and the second shaft is levitated by a magnetic force between the second magnetic part and the fourth magnetic part, thereby levitating the flexible display panel. In addition, the second magnetic part can move relative to the first magnetic part, and the first shaft can be close to or far away from the second shaft under the action of the magnetic field, so that the flexible display panel can be switched back and forth between a folded first state and an unfolded second state.

Fig. 6 is a cross-sectional view of a section B-B of the suspended tension display device in fig. 5.
Referring to fig. 1 to 6, an embodiment of the present application provides a floating tension display device including: a base 1 having a first magnetic portion 11 and a second magnetic portion 12 arranged at intervals along a first direction X; a first shaft 2 extending in a second direction Y intersecting the first direction X, one end of the first shaft 2 being provided with a third magnetic portion 21 so that the first shaft 2 can be suspended in the base 1 by the magnetic force of the first magnetic portion 11 and the third magnetic portion 21; a second shaft 3 extending along the second direction Y, wherein one end of the second shaft 3 is provided with a fourth magnetic portion 31, so that the second shaft 3 can be suspended on the base 1 by the magnetic force of the second magnetic portion 12 and the fourth magnetic portion 31; the second shaft 3 is movably arranged in the first direction X so that the second shaft 3 and the second magnetic part 12 can be moved closer to or farther from the first shaft 2 in the second direction Y; a flexible display panel 4, the flexible display panel 4 being connected to the first shaft 2 and the second shaft 3 at both ends of the extending direction thereof, respectively; the floating stretch display device has a first state and a second state: in the first state, the flexible display panel 4 is wound around the second shaft 3; in the second state, the second shaft 3 and the first shaft 2 are arranged at intervals along the second direction Y; the first shaft 2 and the second shaft 3 are both rotatably arranged; when the first state is changed to the second state, the flexible display panel 4 is rolled out from the second shaft 3; when the second state is changed to the first state, the flexible display panel 4 is wound around the second shaft 3.
With continued reference to fig. 1-6, the flexible display screen is connected to the first shaft 2 and the second shaft 3 and is capable of being wound around the second shaft 3 such that the flexible display panel 4, the first shaft 2 and the second shaft 3 form a reel-like stretched display device. The third magnetic portion 21 provided on the first shaft 2 and the first magnetic portion 11 magnetically suspend the first shaft 2 relative to the first magnetic portion 11. Similarly, the fourth magnetic portion 31 and the second magnetic portion 12 disposed on the second shaft 3 enable the second shaft 3 to float with respect to the second magnetic portion 12 by magnetic force. When both the first shaft 2 and the second shaft 3 are in a floating state, the flexible display panel 4 is also in a floating state. The base 1 is used as a mounting carrier for the first magnetic part 11 and the second magnetic part 12. When both the first shaft 2 and the second shaft 3 are in a floating state, the flexible display panel 4 is in a floating state with respect to the chassis 1.
With continued reference to fig. 1-6, the flexible display panel 4, the first shaft 2 and the second shaft 3 are formed in a reel-like fashion, and accordingly, the floating stretch display device of an embodiment of the present application includes a first state and a second state. When the floating stretch display device is in the first state, the distance between the first shaft 2 and the second shaft 3 is small, and the flexible display panel 4 is wound around the second shaft 3, so that the floating stretch display device is wound and folded. When the floating stretch display device is in the second state, the distance between the first shaft 2 and the second shaft 3 is large, and the flexible display panel 4 is rolled out from the second shaft 3, so that the floating stretch display device is stretched and unfolded.
With continued reference to fig. 1-6, the second magnetic portion 12 can be closer to or farther from the first magnetic portion 11, and the second shaft 3 can be closer to or farther from the first shaft 2 in synchronization. In the process of converting the floating stretching display device from the first state to the second state, the second magnetic part 12 is far away from the first magnetic part 11, the second shaft 3 is far away from the first shaft 2 synchronously under the action of magnetic force, and the flexible display panel 4 wound on the second shaft 3 is pulled and rolled out from the second shaft 3. In the process of converting the floating stretching display device from the second state to the first state, the second magnetic part 12 is close to the first magnetic part 11, the second shaft 3 is synchronously close to the first shaft 2 under the action of magnetic force, and the unfolded flexible display panel 4 is wound on the second shaft 3. By reciprocally moving the second magnetic portion 12 in this manner, it is possible to realize the back-and-forth switching of the floating stretch display device between the first state and the second state, that is, the floating stretch display device back-and-forth switching between the winding-up and the stretching-out.
The second magnetic portion 12 is close to or far from the first magnetic portion 11 along the first direction X, and the first magnetic portion 11 and the second magnetic portion 12 are disposed on the base 1 along the first direction X. When the base 1 is placed horizontally on a stable plane, the first direction X corresponds to the horizontal direction, and at this time, in order to keep the magnetic levitation stable, the first shaft 2 and the second shaft 3 may be disposed along the vertical direction, that is, the second direction Y corresponds to the vertical direction.
Fig. 7 is a cross-sectional view of the suspended tension display device of fig. 6 in section C-C.
Optionally, with continued reference to fig. 6, in conjunction with fig. 7, the floating stretch display device further includes: the pulling mechanism 5 includes: a pulling rope 51, one end of the pulling rope 51 is connected with the first shaft 2, and the other end of the pulling rope 51 is connected with the second shaft 3; in the first state, at least part of the pulling rope 51 is accommodated in the first shaft 2; in the second state, the pulling rope 51 is connected between the first shaft 2 and the second shaft 3, the pulling rope 51 is wound around the second shaft 3, so that when the second state is changed to the first state, the pulling mechanism 5 pulls the pulling rope 51 and drives the second shaft 3 to rotate so as to enable the flexible display panel 4 to be wound around the second shaft 3;
a rotatable steering portion 52 located on a side of the second shaft 3 adjacent to the first shaft 2; the pulling cord 51 is connected to the second shaft 3 via the turning portion 52 and between the second shaft 3, and the direction in which the pulling cord 51 is wound around the second shaft 3 in the second state is opposite to the direction in which the flexible display panel 4 is wound around the second shaft 3 in the first state.
In the process of converting the suspension stretching display device from the second state to the first state, considering that the second shaft 3 in the suspension state is mainly under the action of magnetic force, the pulling mechanism 5 can drive the second shaft 3 to rotate, so that the flexible display panel 4 can be wound on the second shaft 3, and obvious buckling and wrinkling of the part of the flexible display panel 4 between the first shaft 2 and the second shaft 3 are avoided.
The pulling mechanism 5 pulls the rope 51 to rotate the second shaft 3. In the second state, the pulling cord 51 is connected between the first shaft 2 and the second shaft 3, and the pulling cord 51 is wound around the second shaft 3. The pulling cord 51 is pulled during the transition of the floating stretch display device from the second state to the first state. Since part of the pulling rope 51 is wound around the second shaft 3, the second shaft 3 is rotated by the pulling rope 51 after the pulling rope 51 is pulled. As the second shaft 3 rotates, the flexible display panel 4 may be gradually wound around the second shaft 3 until the floating tension display device is in the first state, the flexible display panel 4 may be wound around the second shaft 3, and a portion of the flexible display panel 4 between the first shaft 2 and the second shaft 3 is in a flat state without significant buckling or crinkling. Illustratively, the pulling mechanism 5 may take the form of a motor to pull the pulling cord 51. In the process of switching the floating tension display device from the second state to the first state, the pulling rope 51 pulls the second shaft 3 to rotate, so that the pulling rope 51 is rolled out from the second shaft 3, and the pulling rope 51 is opposite to the winding direction of the flexible display surface AA relative to the second shaft 3 in consideration of the winding of the flexible display panel 4 on the second shaft 3. The steering part 52 can steer the pulling force applied by the pulling rope 51 along the first direction X to the acting force along the tangential direction of the second shaft 3, so that the process of pulling the second shaft 3 to rotate by the pulling rope 51 is more stable, and the pulling rope 51 is prevented from damaging the suspension state of the second shaft 3.
Further, with continued reference to fig. 6 and 7, the flexible display panel 4 includes a display surface AA and an opposite non-display surface NA, and the first shaft 2, the second shaft 3, and the pulling cord 51 are all located on a side of the non-display surface NA of the flexible display panel 4 facing away from the display surface AA. The first shaft 2, the second shaft 3 and the pulling rope 51 are always located on the same side of the flexible display panel 4 when the floating stretch display device is switched back and forth between the first state and the second state. By providing the first shaft 2, the second shaft 3, and the pulling rope 51 on the non-display surface NA side of the flexible display panel 4, it is possible to avoid that the first shaft 2, the second shaft 3, and the pulling rope 51 block the flexible display panel 4 from emitting light. In addition, since the pulling of the pulling rope 51 may cause the rotation of the second shaft 3, the pulling rope 51 and the first shaft 2 are disposed on the same side of the flexible display panel 4 as the second shaft 3, and the pulling rope 51 may be protected by the first shaft 2 and the second shaft 3, so that the pulling rope 51 is difficult to be hooked by a foreign object, and the pulling rope 51 is erroneously pulled, thereby reducing the possibility that the flexible display panel 4 is erroneously wound to be out of a suspended state.
Further, with continued reference to fig. 7, the second shaft 3 includes a shaft body 33 and a shaft sleeve 34; the shaft body 33 is movably disposed in a second state, the shaft sleeve 34 is sleeved outside the shaft body 33, the flexible display panel 4 is fixedly connected with the shaft sleeve 34 and is wound outside the shaft sleeve 34 in the first state, and the traction rope 51 is fixedly connected with the shaft sleeve 34 and is wound outside the shaft sleeve 34 in the second state. The flexible display panel 4 and the pulling cord 51 are connected to the sleeve 34. The sleeve 34 rotates when the floating stretch display device is switched back and forth between the first state and the second state, enabling the flexible display panel 4 to be rolled in or rolled out. That is, in the course of the floating stretch display device being shifted from the second state to the first state, the pulling cord 51 pulls the sleeve 34 to rotate, so that the flexible display panel 4 is wound around the sleeve 34, and the shaft body 33 is relatively stable and in the floating state. Since the shaft sleeve 34 can rotate relative to the shaft body 33, the shaft sleeve 34 can maintain the original posture of the shaft sleeve 34 unchanged when the shaft sleeve 34 rotates, thereby maintaining the stability of the shaft body 33. Since the shaft body 33 is kept in a stable state, the second shaft 3 can be kept in a suspended state.
Fig. 8 is another schematic diagram of a floating stretch display device according to an embodiment of the present application in a first state. Fig. 9 is a schematic diagram of a floating stretch display device in a second state according to an embodiment of the present application.
Optionally, referring to fig. 8 and 9, the floating stretch display device further includes: a fifth magnetic part 13 disposed on a side of the second shaft 3 facing away from the base 1; the sixth magnetic part 32 is disposed on the base 1 through the bracket 14, and the sixth magnetic part 32 and the fifth magnetic part 13 are disposed at intervals, and the sixth magnetic part 32 is located at one side of the fifth magnetic part 13 away from the second shaft 3, so that the second shaft 3 can be suspended on the base 1 through the magnetic force action of the second magnetic part 12 and the fourth magnetic part 31 and the magnetic force action of the fifth magnetic part 13 and the sixth magnetic part 32.
The floating stretching display decoration is folded or unfolded in consideration of the synchronous movement of the second shaft 3 by moving the second magnetic part 12. The strength of the magnetic force applied to the second shaft 3 needs to be greater so that it can remain in a stable suspended state during movement. The fifth magnetic part 13 and the sixth magnetic part 32 can enhance the magnetic force applied to the second shaft 3, so that the second shaft 3 can maintain a stable suspended state during movement. When the second shaft 3 is in the floating state, the second magnetic part 12 is not in contact with the fourth magnetic part 31, the fifth magnetic part 13 is not in contact with the sixth magnetic part 32, and the arrangement of the fifth magnetic part 13 and the sixth magnetic part 32 can enhance the floating stability of the second shaft 3 and can not limit the floating position of the second shaft 3. Further, the second magnetic portion 12 and the sixth magnetic portion 32 are connected to the base 1 through the bracket 14. When the carriage 14 is moved, the second magnetic part 12, the sixth magnetic part 32 and the second shaft 3 are moved synchronously.
Further, the bracket 14 is provided with a yielding space between the second magnetic part 12 and the sixth magnetic part 32, and the second shaft 3 is positioned in the yielding space; the holder 14 is fixedly connected to the second magnetic part 12 such that the holder 14, the second magnetic part 12, the sixth magnetic part 32 and the second shaft 3 are synchronously moved closer to or further from the first shaft 2 in the first direction X. Since the fourth magnetic part 31 and the fifth magnetic part 13 are located at both ends of the second shaft 3, a space for giving way is provided between the second magnetic part 12 and the sixth magnetic part on the bracket 14, so that the suspension of the second shaft 3 can be given way, and the bracket 14 is prevented from interfering with the suspension of the second shaft 3 and the transition of the second shaft 3 between the suspended state and the falling state. Further, the support 14 is fixedly connected to the second magnetic part 12, and the support 14 and/or the second magnetic part 12 can be moved when it is desired to move the second shaft 3.
Fig. 10 is a schematic diagram of the floating stretch display device according to the embodiment of the application after the first magnetic portion and the second magnetic portion are powered off. Fig. 11 is a stress state diagram of a suspension stretching display device according to an embodiment of the application. Fig. 12 is another stress state diagram of the floating stretch display device according to the embodiment of the present application.
Alternatively, referring to fig. 10 to 12, the first magnetic part 11 and the second magnetic part 12 are electromagnets, the first magnetic part 11 applies a first force F1 in the second direction Y to the third magnetic part 21, the first force F1 is a repulsive force, and the second magnetic part 12 applies a second force F2 in the second direction Y to the fourth magnetic part 31, the second force F2 is a repulsive force. The first magnetic part 11 and the second magnetic part 12 can be in the form of electromagnets, and when the current is conducted, the first magnetic part 11 and the second magnetic part 12 generate magnetic fields, so that the first shaft 2 and the second shaft 3 are in a suspension state under the action of magnetic force; when the current is cut off, it can be seen that the magnetic fields of the first magnetic part 11 and the second magnetic part 12 disappear, and the first shaft 2 and the second shaft 3 fall back onto the base 1. In order to ensure that the first shaft 2 and the second shaft 3 are levitated by the magnetic force, the first magnetic part 11 applies a first force F1 in the second direction Y to the third magnetic part 21, and the second magnetic part 12 applies a second force F2 in the second direction Y to the fourth magnetic part 31, both the first force F1 and the second force F2 being repulsive forces.
Further, with continued reference to fig. 11 and 12, the fifth magnetic portion 13 applies a third force F3 in the second direction Y to the sixth magnetic portion 32, and a resultant force direction of the third force F3 and the second force F2 is the same as the direction of the second force F2. In order to allow the second shaft 3 to be in a stable suspended state, there is a vertically upward component of the resultant force of the second force F2 and the third force F3 to balance the weight of the second shaft 3, thereby placing the second shaft 3 in a suspended state. In consideration of the second force F2 as a repulsive force, there is an upward component to the force of the second shaft 3, and thus, there may be an upward or downward component to the direction of the force of the third force F3 to the second shaft 3, that is, the third force F3 may be a repulsive force or an attractive force. When the third force F3 is a repulsive force, the resultant force direction of the third force F3 and the second force F2 is the same as the direction of the second force F2, i.e., the third force F3 is smaller than the second force F2. When the third force F3 is an attractive force, the resultant force direction of the third force F3 and the second force F2 is the same as the direction of the second force F2 regardless of the magnitude of the third force F3. It should be noted that, when the third acting force F3 is an attractive force, the third acting force F3 should not be too large, which would result in that the resultant force between the third acting force F3 and the second acting force is greater than the gravity of the second shaft 3, so that the second shaft 3 may be pressed against the sixth magnetic portion 32, thereby affecting the suspension of the second shaft 3.
Further, the second magnetic component is movably disposed on the base 1 along the first direction X, so as to drive the second shaft 3 to move by the movement of the second magnetic portion 12. One end of the bracket 14 is fixed to the second magnetic part 12 to drive the sixth magnetic part 32 to move by the movement of the second magnetic part 12. After the second magnetic part 12 is fixed on the bracket 14, when the bracket 14 is moved along the first direction X relative to the base 1, the second magnetic part 12 and the sixth magnetic part 32 move, so as to drive the second shaft 3 to move along the first direction X.
Further, the bracket 14, the first shaft 2 and the second shaft 3 are all located on the same side of the flexible display panel 4. Since the first shaft 2 and the second shaft 3 are both located on the side corresponding to the non-display surface NA of the flexible display panel 4, the stand 14 is also located on the side corresponding to the non-display surface NA of the flexible display panel 4, thereby avoiding the stand 14 from shielding the flexible display panel 4.
Fig. 13 is a schematic view of a floating stretch display device according to an embodiment of the present application in a first state. Fig. 14 is a schematic view of a floating stretching display device and a structure of the inside of a chassis according to an embodiment of the present application.
Further, referring to fig. 13 and 14, the base 1 further includes: a rack 16, the second magnetic portion 12 being fixed to the rack 16; the gear 15 is meshed with the rack 16, and the gear 15 is rotatably arranged so that the gear 15 can drive the second magnetic piece to move along the first direction X through the rack 16. The base 1 informs the second magnetic part 12 to move in the first direction X by means of the rack 16 of the pinion 15. When the gear 15 rotates, the rack 16 moves in the first direction X by the engagement of the gear 15 with the rack 16, and the second magnetic portion 12 moves in the first direction X together with the rack 16. The rotation of the gear 15 may be driven by a motor, or the gear 15 may be rotated manually, for example.
