Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a display device provided in an embodiment of the present application in a folded state, and fig. 2 is a schematic view of the display device shown in fig. 1 in an unfolded state. The display device 100 may include a first moving body 110, a second moving body 120, and a flexible screen assembly 130. The first and second moving

bodies

110 and 120 are slidably connected such that the first and second moving

bodies

110 and 120 are relatively moved in a direction approaching or separating from each other, whereby switching between the expanded state and the collapsed state can be achieved. In this regard, the closed state may refer to fig. 1, that is, a state in which the first moving body 110 and the second moving body 120 are relatively moved in a direction to approach each other and finally formed. In this case, the unfolded state may refer to fig. 2, which is a state in which the first moving body 110 and the second moving body 120 are relatively moved in a direction away from each other.

It should be noted that the unfolding state of the first moving body 110 and the second moving body 120 may be various, for example, the maximum moving distance of the first moving body 110 and the second moving body 120 in the direction away from each other is H, and the first moving body 110 and the second moving body 120 may move away from each other in the folded state, so as to achieve the unfolding state with different distances formed by the equal distance of one quarter H, one half H, and three quarters H. The state of the distance gradually becoming farther may be defined as a first developed state, a second developed state, a third developed state, and the like in this order.

It should be noted that when the first moving body 110 and the second moving body 120 are in the first deployed state, such as the distance of the relative moving away of the first moving body 110 and the second moving body 120 in the first deployed state is a quarter H, the first moving body 110 and the second moving body 120 may still perform the relative moving away to reach the second deployed state, such as the distance of the relative moving away of the first moving body 110 and the second moving body 120 in the second deployed state is a half H.

It is to be understood that the one or more deployment states of the first moving body 110 and the second moving body 120 of the embodiment of the present application are merely illustrative and do not constitute a limitation on the deployment states of the first moving body 110 and the second moving body 120 of the embodiment of the present application.

One end of the flexible screen assembly 130 is fixedly connected to the first moving body 110, and the other end of the flexible screen assembly 130 is fixedly connected to the second moving body 120. The first and second moving

bodies

110 and 120 may support the flexible screen assembly 130. The first moving body 110 and the second moving body 120 may drive the flexible screen assembly 130 to move together or drive the flexible screen assembly 130 to move during the mutual movement, so that the length of the flexible screen assembly 130 may be adjusted, and the size of the display area of the display device 100 may be changed.

When the first and second moving

bodies

110 and 120 relatively move in a direction to approach each other, the first and second moving

bodies

110 and 120 may drive a portion of the flexible screen assembly 130 to be received inside the display device 100, such as inside the second moving body 120 of the display device 100. When the first and second moving

bodies

110 and 120 are relatively moved in a direction away from each other, the first and second moving

bodies

110 and 120 may drive a portion of the flexible screen assembly 130 to protrude from the inside of the display device 100, such as the second moving body 120.

The non-display surface of the flexible screen assembly 130 is disposed on one surface of the first moving body 110 and one surface of the second moving body, or the non-display surface of the flexible screen assembly 130 is disposed on one surface of the first moving body 110 and one surface of the second moving body 120. The flexible screen assembly 130 covers one surface of the first moving body 110 and one surface of the second moving body 120 regardless of whether the first moving body 110 and the second moving body 120 are in the collapsed state or in the expanded state, but the covered areas are different in size.

When the first moving body 110 and the second moving body 110 are in the collapsed state, a portion of the other face of the first moving body 110 is located inside the second moving body 120. Or when the first moving body 110 and the second moving body 120 are in the folded state, a part of the first moving body 110 is received in the second moving body 120, and at this time, the other surface of the first moving body 110 is shielded by the second moving body 120. And the other side of the second moving body 120 serves as a housing of the display device 100.

When the first moving body 110 and the second moving body 120 are in the unfolded state, a part of the other side of the first moving body 110 is located outside the second moving body 120, or is exposed outside, or is not shielded by the second moving body 120.

The present embodiment is configured such that, when the first moving body 110 and the second moving body 120 are in the collapsed state, the side positions of the first moving body 110 and the second moving body 120 are adjacent, such as abutting together. So that the overall structural integrity of the first and second moving

bodies

110 and 120 can be seen from the appearance.

The first moving body 110 and the second moving body 120 may be manually driven such that the first moving body 110 and the second moving body 120 perform a mutual movement. The first moving body 110 and the second moving body 120 may be electrically driven to move relative to each other, such as one or more driving motors, as many transmission assemblies as there are motors, and the like. The driving motor may drive the first and second moving

bodies

110 and 120 to move closer to or away from each other through the transmission assembly. The first and second moving

bodies

110 and 120 may also be magnetically driven.

The two sets of driving mechanisms may drive the first moving body 110 and the second moving body 120 together to move the first moving body 110 and the second moving body 120.

Two coils of the driving assembly 140 are provided to the first moving body 110, such as a first coil 141 and a third coil 143 provided to the first moving body 110, and the first coil 141 and the third coil 143 are provided spaced apart. In some embodiments, the first moving body 110 may include a first end 111 and a second end 112 opposite to each other, wherein the first end 111 may be one end of the display device 100, and the second moving body 120 may be away from the first end 111.

Such as the second coil 142 and the fourth coil 144, are provided to the second moving body 120, and the second coil 142 and the fourth coil 144 are provided spaced apart. In some embodiments, the second moving body 120 includes a first portion 121 and a second portion 122 fixedly connected to each other, the first portion 121 may move within the first moving body 110, and the second portion 122 may be held at an outer side of the first moving body 110. The second and

fourth coils

142 and 144 are disposed on both sides of the second portion 122, and both the second and

fourth coils

142 and 144 are adjacent to the first portion 121.

When the display device is in the folded state, referring to fig. 3 and 4, the second end portion 112 of the first moving body 110 abuts against the second portion 122 of the second moving body 120, the first coil 141 and the second coil 142 are adjacent, the first coil 141 and the second coil 142 are spaced apart from each other without contact, and the first coil 141 and the second coil 142 are opposite to each other. The third and

fourth coils

143 and 144 are adjacent, the third and

fourth coils

143 and 144 are spaced apart without contacting, and the third and

fourth coils

143 and 144 are located opposite to each other.

When the display device is in the unfolded state, referring to fig. 5 and 6, the second end portion 112 of the first moving body 110 is spaced apart from the second portion 122 of the second moving body 120, the first coil 141 and the second coil 142 are spaced apart without contacting, and the first coil 141 and the second coil 142 are located opposite to each other. The third coil 143 and the fourth coil 144 are spaced apart without contacting, and the third coil 143 and the fourth coil 144 are located opposite to each other.

In the embodiment of the present invention, the first coil 141 and the second coil 142 may have the same size, and the third coil 143 and the fourth coil 144 may have the same size. The first coil 141 and the third coil 143 of the embodiment of the present application may have the same size. Such as the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144, all have the same size.

The embodiment of the application can be provided with the placing groove to place the coil. Such as the first moving body 110 provided with the first placing groove 151 and the third placing groove 153, the first placing groove 151 may place the first coil 141, i.e., the first coil 141 may be provided in the first placing groove 151. The third placing groove 153 may place the third coil 143, that is, the third coil 143 may be disposed in the third placing groove 153. The second moving body 120 is provided with a second placing groove 152 and a fourth placing groove 154, and the second placing groove 152 may place the second coil 142, that is, the second coil 142 may be disposed in the second placing groove 152. The fourth placement groove 154 may place the fourth coil 144, i.e., the fourth coil 144 may be disposed within the fourth placement groove 154.

In the actual assembly process, the coil guide posts can be arranged to fix the coil. Such as the first coil 141, is sleeved on the first guide post, i.e. the first coil 141 is wound on the first guide post. The second coil 142 is sleeved on the second guide post, i.e. the second coil 142 is wound on the second guide post. The third coil 143 is sleeved on the third guide post, that is, the third coil 143 is wound on the third guide post. The fourth coil 144 is sleeved on the fourth guiding post, i.e. the fourth coil 144 is wound on the fourth guiding post. The guide posts may also be the same size, such as being cylindrical in structure.

It should be noted that, since each guide post is covered by the coil, it is not shown in the drawings.

The first portion 121 and the second portion 122 can be fixedly connected together by means of integral molding, such as injection molding and machining. The first portion 121 and the second portion 122 may also be fixedly connected together in other manners, such as by using a connecting member such as a screw connection.

In some embodiments, one or more rails 1211 may be disposed on the first portion 121, such as one rail 1211 disposed on each side of the first portion 121. Correspondingly, the first moving body is provided with one or more guide grooves 113, such as one guide groove 113 provided on each side of the first moving body 100, and one guide groove 113 can receive one guide rail 1211. The guide rail 1211 can move, such as slide, within the guide groove 113. It is understood that the number of the guide grooves 113 is the same as the number of the guide rails 1211. Thus, the present embodiment may employ the cooperation of the plurality of guide grooves 113 and the guide rail 1211 to more facilitate the movement of the first moving body 110 and the second moving body 120. Even if one set of driving mechanism (in which two coils that are fitted to each other such as the third coil 143 and the fourth coil 144) is broken in the embodiment of the present application, the first moving body 110 and the second moving body 120 can be driven to slide along the fitting direction of the slide rail 1211 and the guide groove 113 by one set of driving mechanism (in which two coils that are fitted to each other such as the first coil 141 and the second coil 142).

The first coil 141 is energized, and the second coil 142, the third coil 143, and the fourth coil 144 are energized in the embodiment of the present application, wherein a first attractive force or a first repulsive force can be generated between the first coil 141 and the second coil 142, and a second attractive force and a second repulsive force can be generated between the third coil 143 and the fourth coil 144, so that the driving of the first moving body 110 and the second moving body 120 can be realized.

In some embodiments, a first attractive force generated between the first coil 141 and the second coil 142, and a second attractive force generated between the third coil 143 and the fourth coil 144 may drive the first moving body 110 and the second moving body 120 to move in a direction approaching each other in cooperation. A first repulsive force generated between the first coil 141 and the second coil 142 and a second repulsive force generated between the third coil 143 and the fourth coil 144 may drive the first moving body 110 and the second moving body 120 to move in a direction away from each other in common. That is, the first attractive force and the second attractive force act in the same direction, and the first repulsive force and the second repulsive force act in the same direction.

In order to keep the driving force to each part of the first and second moving

bodies

110 and 120 the same, the magnitude of the first attraction force and the magnitude of the second attraction force defined in the embodiments of the present application are the same, and the magnitude of the first repulsion force and the magnitude of the second repulsion force are the same. It should be noted that the magnitude of the acting force of the first attraction force may be different from the magnitude of the acting force of the second attraction force, and the magnitude of the acting force of the first repulsion force may be different from the magnitude of the acting force of the second repulsion force.

Referring to fig. 7, fig. 7 is a block diagram of a display device according to an embodiment of the present disclosure, and the display device 100 may further include a processor 160 and a memory 170. The memory 170 is electrically coupled to the processor 160, such as by signal lines, and the memory 170 may store instructions, data, systems, and the like. The processor 160 may execute data stored by the memory 170 to perform some function. Processor 160 is also electrically connected, such as with signal wires, to flexible screen assembly 130, first coil 141, second coil 142, third coil 143, and fourth coil 144. Processor 160 may control flexible screen assembly 130 to display a picture. The processor 160 may control the first, second, third and

fourth coils

141, 142, 143 and 144 to be energized.

Although not shown in the drawings, it is understood that the display device 100 of the embodiment of the present application may further include a power supply, which may supply power to the flexible screen assembly 130, the first coil 141, the second coil 142, the third coil 143, the fourth coil 144, and the like.

Referring to fig. 8, fig. 8 is an equivalent schematic diagram of the display device switched from the folded state to the unfolded state according to the embodiment of the present application. Wherein the equivalent diagram of the folded state of the display device is identified as 100A and the equivalent diagram of the unfolded state of the display device is identified as 100B.

When the display device 100 is in the folded state and the user needs to unfold the display device 100, the embodiment of the present application may design a control switch on the display device 100, and electrically connect the control switch with the processor 160. The user can control the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144 by the control switches. Such as the processor 160, controls the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144 to be energized according to a control signal controlling the switches.

The processor 160 may control the first coil 141 to pass the first current, so that the first coil 141 generates two electrodes, i.e., an N pole and an S pole. The processor 160 may control the second coil 142 to pass the second current such that the second coil 142 generates two electrodes, an N-pole and an S-pole. The processor 160 may control the third coil 143 to pass the third current such that the third coil 143 generates two electrodes, i.e., an N-pole and an S-pole. The processor 160 may control the fourth coil 144 to pass the fourth current such that the fourth coil 144 generates two electrodes, an N-pole and an S-pole. The first current, the second current, the third current and the fourth current may be the same or different.

In the embodiment of the present application, the processor 160 controls the first coil 141 to apply the first current, controls the second coil 142 to apply the second current, and controls the direction of the first current and the direction of the second current, so that the polarities of the adjacent ends of the first coil 141 and the second coil 142 are the same, such as both N-poles. Note that the polarities of the adjacent ends of the first coil 141 and the second coil 142 may be both S-poles. So that the first repulsive force F1 can be generated between the first coil 141 and the second coil 142.

The processor 160 of the embodiment of the present application controls the third coil 143 to apply the third current, controls the fourth coil 144 to apply the fourth current, and controls the direction of the third current and the direction of the fourth current, so that the polarities of the adjacent ends of the third coil 143 and the fourth coil 144 are the same, such as both N-poles. Note that, the polarities of the adjacent ends of the third coil 143 and the fourth coil 144 may be both S-poles. So that a second repulsive force F2 can be generated between the third coil 143 and the fourth coil 144.

The first repulsive force F1 generated by the interaction of the first and

second coils

141 and 142 has the same direction as the second repulsive force F2 generated by the interaction of the third and

fourth coils

143 and 144, and thus the first and second moving

bodies

110 and 120 can be driven together to move away from each other, so that the display device 100 is unfolded. That is, the embodiment of the present application may realize the switching of the display device 100 from the folded state 100A to the unfolded state 100B by the first repulsive force F1 and the second repulsive force F2.

In the embodiment of the present application, when the first current, the second current, the third current and the fourth current have the same magnitude, the first repulsive force F1 and the second repulsive force F2 are substantially equal, so that the driving of the first moving body 110 and the second moving body 120 by the driving assembly 140 is more uniform and stable.

The processor 160 of the embodiment of the present application may control the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144 to be energized simultaneously, so that the first repulsive force F1 generated by the first coil 141 and the second coil 142 may be synchronized with the second repulsive force F2 generated by the third coil 143 and the fourth coil 144, for the purpose of synchronously driving the first moving body 110 and the second moving body 120.

Referring to fig. 9, fig. 9 is an equivalent schematic diagram of a display device switched from an unfolded state to a folded state according to an embodiment of the present application.

When the display apparatus 100 is in the unfolded state and the user needs to fold the display apparatus 100, the user can control the first, second, third and

fourth coils

141, 142, 143 and 144 through the control switch. Such as the processor 160, controls the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144 to be energized according to a control signal controlling the switches.

The processor 160 may control the first coil 141 to pass the fifth current, so that the first coil 141 generates two electrodes, i.e., an N pole and an S pole. The processor 160 may control the second coil 142 to pass the sixth current such that the second coil 142 generates two electrodes, an N-pole and an S-pole. The processor 160 may control the third coil 143 to pass a seventh current such that the third coil 143 generates two electrodes, i.e., an N-pole and an S-pole. The processor 160 may control the fourth coil 144 to pass the eighth current such that the fourth coil 144 generates two electrodes, an N-pole and an S-pole. The magnitudes of the fifth current, the sixth current, the seventh current and the eighth current may be the same or different.

In the embodiment of the present invention, the processor 160 controls the first coil 141 to apply the fifth current, and controls the second coil 142 to apply the sixth current, and controls the direction of the fifth current and the direction of the sixth current, so that the polarities of the ends of the first coil 141 and the second coil 142 adjacent to each other are different, for example, the polarity of the end of the first coil 141 and the end of the second coil 142 adjacent to each other is S-pole, and the polarity of the end of the second coil 142 adjacent to the first coil 141 is N-pole. It should be noted that the polarity of the end of the first coil 141 adjacent to the second coil 142 is not limited to this, and for example, the polarity of the end of the first coil 141 adjacent to the second coil 142 is N-pole, and the polarity of the end of the second coil 142 adjacent to the first coil 141 is S-pole. So that the first attractive force F3 can be generated between the first coil 141 and the second coil 142.

The processor 160 of the embodiment of the present application controls the third coil 143 to pass the seventh current, and controls the fourth coil 144 to pass the eighth current, and controls the direction of the seventh current and the direction of the eighth current so that the polarities of the ends of the third coil 143 and the fourth coil 144 adjacent to each other are different, such as the polarity of the end of the third coil 143 adjacent to the fourth coil 144 is S-pole, and the polarity of the end of the fourth coil 144 adjacent to the third coil 143 is N-pole. It should be noted that the polarity of the end of the third coil 143 adjacent to the fourth coil 144 is not limited thereto, and for example, the polarity of the end of the third coil 143 adjacent to the fourth coil 144 is N-pole, and the polarity of the end of the fourth coil 144 adjacent to the third coil 143 is S-pole. So that the second attractive force F4 can be generated between the third coil 143 and the fourth coil 144.

That is, the embodiment of the application can realize the switching of the display device 100 from the unfolded state 100B to the folded state 100A by the first attractive force F3 and the second attractive force F4.

In the embodiment of the present application, when the magnitudes of the fifth current, the sixth current, the seventh current and the eighth current are the same, the first attraction force F3 and the second attraction force F4 are substantially equal, so that the driving of the first moving body 110 and the second moving body 120 by the driving assembly 140 is more uniform and stable.

The processor 160 of the embodiment of the present application may control the first coil 141, the second coil 142, the third coil 143, and the fourth coil 144 to be energized simultaneously, so that the first attractive force F3 generated by the first coil 141 and the second coil 142 may be synchronized with the second attractive force F4 generated by the third coil 143 and the fourth coil 144, thereby achieving the purpose of synchronously driving the first moving body 110 and the second moving body 120.

In some embodiments, the same end of the first coil 141 and the third coil 143 has the same polarity, and the same end of the second coil 142 and the fourth coil 144 has the same polarity, thereby avoiding the coils from previously affecting each other.

That is, the driving assembly 140 shown in fig. 10 includes only the first coil 141 and the second coil 142. The specific driving manner of the first coil 141 and the second coil 142 can refer to the above, and is not described herein again.

It will be appreciated that the drive assembly of the embodiments of the present application may also include more sets of drive mechanisms, such as the drive assembly may also include cooperating fifth and sixth coils.

It should be noted that the embodiment of the present application may replace one of the two coils that are engaged with each other with a magnet. Such as a drive assembly including a first coil and a first magnet cooperating with the first coil. For another example: the driving assembly comprises a first coil and a first magnet matched with the first coil, and a second coil and a second magnet matched with the second coil. The current of the first coil and the second coil can be controlled by the processor, so that the first coil and the second coil generate polarities to be matched with the first magnet and the second magnet, and then the first moving body and the second moving body are driven to move.

It should be noted that, because the magnet has magnetism, it may affect the rf performance of the display device 100. Thus, some embodiments of the present application use coils rather than magnets to improve radio frequency performance.

It should be noted that after the magnet is assembled, the magnetism of the magnet is fixed and not adjustable, and the adjustment can be realized only by adjusting the coil, and the adjustment range is not equal to the adjustment performance of the coil.
