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, the suspension of the display screen is usually realized in the form of magnetic suspension, that is, the display screen is suspended by the action of magnetic force. However, the magnetic suspension display screen is difficult to realize flexible deformation of the display screen, and especially when the display screen is a flexible display screen, the flexible display screen is difficult to realize rolling, folding or stretching and unfolding.
The applicant has found that when the display screen is in a floating state, the display screen is not usually subjected to other obvious external forces except for magnetic force, so that if the flexible display screen is folded or unfolded in a reel-like manner, external force is applied to fold or unfold the flexible display panel. However, the flexible display screen is in a suspended state, and once an external force is applied, the force balance of the suspended state of the flexible display screen is destroyed, so that the flexible display screen is separated from the suspended state.
In view of the above problems, the applicant has proposed a levitating and stretching display device in which a first magnetic portion and a second magnetic portion are provided on a base, and 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, so that the flexible display panel is levitated. In addition, the second magnetic part can move relative to the first magnetic part, and under the action of a magnetic field, the first shaft can be close to or far away from the second shaft, so that the flexible display panel can be switched back and forth between a first folded state and a second unfolded state.

Referring to fig. 1 to 6, an embodiment of the present application provides a floating stretching display device, including: a base 1 having a first magnetic part 11 and a second magnetic part 12 spaced apart from each other in a first direction X; a first shaft 2 extending along a second direction Y, the second direction Y intersecting the first direction X, and a third magnetic part 21 arranged at one end of the first shaft 2, so that the first shaft 2 can be suspended on the base 1 by the magnetic force of the first magnetic part 11 and the third magnetic part 21; a second shaft 3 extending along the second direction Y, one end of the second shaft 3 being provided with a fourth magnetic part 31, so that the second shaft 3 can be suspended on the base 1 by the magnetic force of the second magnetic part 12 and the fourth magnetic part 31; the second shaft 3 is movably disposed in the first direction X so that the second shaft 3 and the second magnetic part 12 can approach or depart from the first shaft 2 in the second direction Y; the flexible display panel AA plate 4 is connected with the first shaft 2 and the second shaft 3 at two ends of the flexible display panel AA plate 4 in the extending direction respectively; the floating stretch display device has a first state and a second state: in the first state, the flexible display panel AA sheet 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 can be rotatably arranged; when the first state is changed into the second state, the flexible display panel AA plate 4 is rolled out from the second shaft 3; when the second state is changed to the first state, the flexible display panel AA sheet 4 is wound around the second shaft 3.
With continued reference to fig. 1-6, the flexible display is coupled to the first shaft 2 and the second shaft 3 and can be wrapped around the second shaft 3 such that the flexible display AA sheet 4, the first shaft 2, and the second shaft 3 form a reel-like stretched display. The third magnetic part 21 provided on the first shaft 2 and the first magnetic part 11 enable the first shaft 2 to float relative to the first magnetic part 11 through magnetic force. Similarly, the fourth magnetic part 31 disposed on the second shaft 3 and the second magnetic part 12 enable the second shaft 3 to float relative to the second magnetic part 12 through the magnetic force. When the first shaft 2 and the second shaft 3 are both in a floating state, the flexible display panel AA 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 the first shaft 2 and the second shaft 3 are both in a floating state, the flexible display panel AA panel 4 is in a floating state with respect to the base 1.
With continued reference to fig. 1 to 6, the flexible display panel AA panel 4, the first shaft 2 and the second shaft 3 form a reel-like form, and accordingly, the floating stretching display device of the embodiment of the present application includes a first state and a second state. When the 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 AA plate 4 is wound around the second shaft 3, so that the display device is wound and folded. When the 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 AA plate 4 is rolled out from the second shaft 3, so that the display device is stretched and unfolded.
With continued reference to fig. 1-6, the second magnetic part 12 can be closer to or farther from the first magnetic part 11, and the second shaft 3 can be synchronously closer to or farther from the first shaft 2. 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 synchronously far away from the first shaft 2 under the action of magnetic force, and the flexible display panel AA plate 4 wound on the second shaft 3 is pulled and is wound 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 close to the first shaft 2 synchronously under the action of magnetic force, and the unfolded flexible display panel AA panel 4 is wound on the second shaft 3. By moving the second magnetic part 12 to and fro in this way, the floating and stretching display device can be switched back and forth between the first state and the second state, that is, the floating and stretching display device is switched back and forth between winding, folding and stretching.
It should be noted that the second magnetic part 12 is close to or far from the first magnetic part 11 along the first direction X, and the first magnetic part 11 and the second magnetic part 12 are disposed on the base 1 along the first direction X. When the base 1 is horizontally placed on a stable plane, the first direction X corresponds to the horizontal direction, and in this case, in order to maintain the stability of the magnetic levitation, the first shaft 2 and the second shaft 3 may be arranged in the vertical direction, i.e., the second direction Y corresponds to the vertical direction.
Fig. 7 is a cross-sectional view of the levitation tension display apparatus of fig. 6 taken along a C-C section.
Optionally, with continuing reference to fig. 6 in conjunction with fig. 7, the floating stretch display device further comprises: a pulling mechanism 5, comprising: 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, and the pulling rope 51 is wound on 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, and the flexible display panel AA plate 4 is wound on the second shaft 3; a rotatable steering portion 52 located on a side of the second shaft 3 close to the first shaft 2; the pulling rope 51 is connected to the second shaft 3 via the turning portion 52, and the direction in which the pulling rope 51 is wound around the second shaft 3 in the second state is opposite to the direction in which the flexible display panel AA panel 4 is wound around the second shaft 3 in the first state.
In the process of switching 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 acted by magnetic force, the traction mechanism 5 can drive the second shaft 3 to rotate, so that the flexible display panel AA plate 4 can be wound on the second shaft 3, and the part of the flexible display panel AA plate 4 between the first shaft 2 and the second shaft 3 is prevented from obviously buckling and wrinkling.
The pulling mechanism 5 rotates the second shaft 3 by pulling the rope 51. In the second state, the pulling rope 51 is connected between the first shaft 2 and the second shaft 3, and the pulling rope 51 is wound around the second shaft 3. In the process of switching the floating stretch display device from the second state to the first state, the pulling rope 51 is pulled. Since part of the pulling rope 51 is wound around the second shaft 3, when the pulling rope 51 is pulled, the second shaft 3 is driven by the pulling rope 51 to rotate. As the second shaft 3 rotates, the flexible display panel AA sheet 4 will gradually wrap around the second shaft 3 until the floating extension display device is in the first state, the flexible display panel AA sheet 4 will wrap around the second shaft 3, and the portion of the flexible display panel AA sheet 4 between the first shaft 2 and the second shaft 3 is in a flat state without significant buckling or wrinkling. Illustratively, the pulling mechanism 5 may take the form of a motor to pull the pulling rope 51. In the process of switching the floating stretch 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 wound out of the second shaft 3, and considering that the flexible display panel AA panel 4 is wound on the second shaft 3, the winding direction of the pulling rope 51 and the flexible display panel AA is opposite to the winding direction of the second shaft 3. The turning part 52 is arranged to turn the pulling force applied by the pulling rope 51 in the first direction X into an acting force in the tangential direction of the second shaft 3, so that the process of the pulling rope 51 pulling the second shaft 3 to rotate 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 AA panel 4 comprises a display surface AA and an opposite non-display surface NA, and the first shaft 2, the second shaft 3 and the pulling rope 51 are all located on a side of the non-display surface NA of the flexible display panel AA 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 AA panel 4 when the hovering and stretching display device is switched back and forth between the first state and the second state. The first shaft 2, the second shaft 3 and the pulling rope 51 are arranged on one side of the non-display surface NA of the flexible display surface AA plate 4, so that the first shaft 2, the second shaft 3 and the pulling rope 51 can be prevented from blocking the flexible display surface AA plate 4 to emit light. In addition, since the pulling of the pulling rope 51 causes the rotation of the second shaft 3, the pulling rope 51, the first shaft 2 and the second shaft 3 are provided on the same side of the flexible display panel AA panel 4, and the pulling rope 51 can be protected by the first shaft 2 and the second shaft 3, so that the pulling rope 51 is not easily caught by a foreign object and the pulling rope 51 is not pulled by mistake, thereby reducing the possibility that the flexible display panel AA panel 4 is wound by mistake and is out of a floating state.
Further, with continued reference to fig. 7, the second shaft 3 includes a shaft body 33 and a sleeve 34; the shaft body 33 is movably arranged in a second state, the shaft sleeve 34 is sleeved outside the shaft body 33, in the first state, the flexible display panel AA plate 4 is fixedly connected with the shaft sleeve 34 and wound outside the shaft sleeve 34, and in the second state, the pulling rope 51 is fixedly connected with the shaft sleeve 34 and wound outside the shaft sleeve 34. The flexible display panel AA panel 4 and the pulling rope 51 are both connected to the shaft sleeve 34. When the suspension stretching display device is switched back and forth between the first state and the second state, the shaft sleeve 34 rotates, and the rolling-in or rolling-out of the flexible display panel AA plate 4 is realized. That is, in the process of switching the floating stretch display device from the second state to the first state, the pulling rope 51 pulls the shaft sleeve 34 to rotate, so that the flexible display panel AA sheet 4 is wound on the shaft sleeve 34, and the shaft body 33 is relatively stable and in a floating state. Since the sleeve 34 can rotate relative to the shaft body 33, the sleeve 34 can maintain its original posture when the sleeve 34 rotates, thereby maintaining the stability of the shaft body 33. Since the shaft body 33 is maintained in a stable state, the second shaft 3 can be maintained in a floating state.
Fig. 8 is another schematic view of the levitation stretch display device according to the embodiment of the present application in the first state. Fig. 9 is a schematic view of a floating stretch display device according to an embodiment of the present application in a second state.
Alternatively, referring to fig. 8 and 9, the floating stretch display device further includes: the fifth magnetic part 13 is arranged on one side of the second shaft 3, which is far away from the base 1; the sixth magnetic part 32 is disposed on the base 1 through the bracket 14, the sixth magnetic part 32 and the fifth magnetic part 13 are disposed at an interval, and the sixth magnetic part 32 is located on a 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 by moving the second magnetic part 12 to drive the second shaft 3 to move synchronously. The strength of the magnetic force applied to the second shaft 3 needs to be greater to maintain a stable suspension state during the 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 levitation 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 fifth magnetic part 13 and the sixth magnetic part 32 are arranged to enhance the stability of the floating of the second shaft 3 without limiting the floating position of the second shaft 3. Further, the second magnetic part 12 and the sixth magnetic part 32 are connected with 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 move in synchronization.
Further, the bracket 14 is provided with an abdicating space between the second magnetic part 12 and the sixth magnetic part 32, and the second shaft 3 is located in the abdicating space; the bracket 14 is fixedly connected to the second magnetic part 12, so that the bracket 14, the second magnetic part 12, the sixth magnetic part 32 and the second shaft 3 are synchronously close to or far from the first shaft 2 along the first direction X. Since the fourth magnetic part 31 and the fifth magnetic part 13 are located at two ends of the second shaft 3, a space for abdicating is provided between the second magnetic part 12 and the sixth magnetic part on the bracket 14, which can abdicating the suspension of the second shaft 3, and prevent the bracket 14 from interfering with the suspension of the second shaft 3 and prevent the second shaft 3 from switching between the suspended state and the falling state. Furthermore, the holder 14 is fixedly connected to the second magnetic part 12, and when it is desired to move the second shaft 3, the holder 14 and/or the second magnetic part 12 can be moved.
Fig. 10 is a schematic diagram illustrating the first magnetic part and the second magnetic part of the display device according to the embodiment of the present disclosure after being powered off. Fig. 11 is a force state diagram of the floating stretching display device according to the embodiment of the present application. Fig. 12 is another force state diagram of the levitation stretching 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 both electromagnets, the first magnetic part 11 applies a first acting force F1 in the second direction Y to the third magnetic part 21, the first acting force F1 is a repulsive force, the second magnetic part 12 applies a second acting force F2 in the second direction Y to the fourth magnetic part 31, and the second acting force F2 is a repulsive force. The first magnetic part 11 and the second magnetic part 12 may be in the form of electromagnets, and when the current is conducted, the first magnetic part 11 and the second magnetic part 12 both generate a magnetic field, so that the first shaft 2 and the second shaft 3 are in a floating state under the action of the 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 acting force F1 along the second direction Y to the third magnetic part 21, and the second magnetic part 12 applies a second acting force F2 along the second direction Y to the fourth magnetic part 31, wherein the first acting force F1 and the second acting force F2 are repulsive forces.
Further, with continued reference to fig. 11 and 12, fifth magnetic part 13 applies third acting force F3 in second direction Y to sixth magnetic part 32, and the resultant force of third acting force F3 and second acting force F2 is in the same direction as second acting force F2. In order to allow the second shaft 3 to be in a stable floating state, the resultant force of the second acting force F2 and the third acting force F3 has a vertically upward component to balance the gravity of the second shaft 3, thereby allowing the second shaft 3 to be in a floating state. Considering that the second force F2 is a repulsive force, there is an upward component in the force acting on the second shaft 3, and therefore, there may be an upward or downward component in the direction of the force acting on the second shaft 3 by the third force F3, i.e., the third force F3 may be a repulsive force or an attractive force. When the third acting force F3 is a repulsive force, the direction of the resultant of the third acting force F3 and the second acting force F2 is the same as the direction of the second acting force F2, i.e., the third acting force F3 is smaller than the second acting force F2. When the third acting force F3 is an attractive force, the direction of the resultant of the third acting force F3 and the second acting force F2 is the same as the direction of the second acting force F2 regardless of the magnitude of the third acting force F3. It should be noted that, when the third force F3 is an attractive force, the third force F3 should not be too large, otherwise the resultant force of the third force F3 and the second force is larger than the gravity of the second shaft 3, so that the second shaft 3 is pressed on the sixth magnetic part 32, and the suspension of the second shaft 3 is affected.
Further, the second magnetic member is movably disposed on the base 1 along the first direction X, so that the second shaft 3 is driven 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 stand 14, the first shaft 2 and the second shaft 3 are all located on the same side of the flexible display panel AA-board 4. Because the first shaft 2 and the second shaft 3 are both located at a side corresponding to the non-display surface NA of the flexible display surface AA plate 4, the bracket 14 is also located at a side corresponding to the non-display surface NA of the flexible display surface AA plate 4, so as to prevent the bracket 14 from shielding the flexible display surface AA plate 4.
Fig. 13 is another schematic view of the floating stretch display device according to the embodiment of the present application in the first state. Fig. 14 is a schematic structural diagram of a floating stretch display device and a base according to an embodiment of the present disclosure.
Further, referring to fig. 13 and 14, the base 1 further includes: the rack 16, the second magnetic part 12 is fixed on the rack 16; the gear 15 is engaged with the rack 16, and the gear 15 is rotatably disposed so that the gear 15 can drive the second magnetic member to move along the first direction X through the rack 16. The base 1 informs the second magnetic part 12 of the movement in the first direction X through the gear 15 and the rack 16.
