Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a foldable screen and electronic device. Background Technology

[0002] With the advancement of technology and the ever-increasing consumer demand, consumers are increasingly looking for large-screen electronic devices, and products such as foldable screen phones and foldable screen laptops, which are convenient to carry and use, are widely welcomed by consumers.

[0003] When foldable phones and laptops are bent and folded, it's difficult to maintain a tight contact between the upper and lower screens using only the hinge joint. Therefore, magnets are typically installed inside the upper and lower screens. When the screen is closed, the magnetic force between the magnets holds the upper and lower screens together. However, because of the attraction between magnets, ferromagnetic objects, such as iron, can easily adhere to the screen. This can cause the objects to get stuck when the screen is closed. Since the screen is flexible, these stuck ferromagnetic objects can easily cause pressure on the screen, resulting in bright spots or black spots, affecting product quality and user experience. Summary of the Invention

[0004] The main purpose of this application is to propose a foldable screen and electronic device, which aims to at least solve the technical problem that existing foldable screen products are prone to trapping ferromagnetic foreign objects when closed, resulting in colored bright spots or black spots on the screen, affecting product quality and user experience.

[0005] To achieve the above objectives, this application provides a foldable screen, which includes:

[0006] Two screens, each with a first end and a second end, wherein the first ends of the two screens are rotatably connected so that the two screens can rotate relative to each other to put the folding screen in an open or closed state.

[0007] A first magnet device and a second magnet device, wherein the first magnet device is installed in one of the screen bodies and the second magnet device is installed in the other screen body, the first magnet device includes a first magnet and a reset structure, and the first magnet is rotatably installed in the corresponding screen body; the second magnet device includes a second magnet.

[0008] When the folding screen is in the closed state, the second magnet attracts the first magnet, causing the magnetic pole distribution direction of the first magnet to change from the first direction to the second direction;

[0009] When the folding screen is in the open state, the reset structure drives the first magnet to rotate, so that the magnetic pole distribution direction of the first magnet changes from the second direction to the first direction, thereby reducing the magnetic force on the screen surface where the first magnet is located.

[0010] This application also proposes an electronic device that uses a foldable screen as described above.

[0011] In this embodiment, the two screens of the foldable screen are rotatably connected by two first ends, allowing them to rotate relative to each other and enabling the folding and unfolding of the screen. When folded, the screen is in a closed state; when unfolded, it is in an open state, ensuring normal use. Furthermore, a first magnet device and a second magnet device are respectively installed within each screen. The first magnet device includes a first magnet and a reset structure, with the first magnet rotatably mounted within the corresponding screen. The second magnet device includes a second magnet. When the foldable screen is in the closed state, the first and second magnets attract each other, causing the magnetic pole distribution direction of the first magnet to change from a first direction to a second direction. The two screens remain in close contact under the influence of this attraction. The reset structure is configured to rotate the first magnet when the foldable screen is in the open state, causing the magnetic pole distribution direction of the first magnet to change from the second direction to the first direction. This reduces the magnetic force on the screen surface where the first magnet is located, thereby reducing the adsorption effect on ferromagnetic foreign objects attached to the screen surface where the first magnet is located. In other words, it makes it difficult for ferromagnetic foreign objects to be adsorbed onto the screen before the foldable screen is folded, preventing the situation where the foldable screen traps ferromagnetic foreign objects when it is closed. This eliminates the risk of ferromagnetic foreign objects squeezing the screen, avoids the appearance of colored bright spots or black spots on the screen, and thus improves product quality and user experience.

[0029] When foldable phones and laptops are bent and folded, it's difficult to maintain a tight contact between the upper and lower screens using only the hinge. Therefore, magnets are usually installed inside the upper and lower screens. When the screen is closed, the magnetic force between the magnets holds the upper and lower screens together. However, because of the attraction between magnets, ferromagnetic foreign objects, such as iron, can easily adhere to the screen. This can cause foreign objects to get stuck when the screen is closed. Since the screen is flexible, such as an AMOLED screen, these stuck ferromagnetic foreign objects can easily cause pressure on the screen, resulting in bright spots or black spots, affecting product quality and user experience.

[0030] This application provides a foldable screen and electronic device that solves the above-mentioned problems.

[0031] like Figures 1 to 6 As shown, in one embodiment of this application, the folding screen 100 includes two screen bodies 10, a first magnet device 20, and a second magnet device 30. Each screen body 10 has a first end and a second end at its two ends, respectively. The first ends of the two screen bodies 10 are rotatably connected, allowing the two screen bodies 10 to rotate relative to each other to bring the folding screen 100 into an open or closed state. One screen body 10 houses the first magnet device 20, and the other screen body 10 houses the second magnet device 30. The first magnet device 20 includes a first magnet 21 and a reset structure 50. A magnet 21 is rotatably mounted inside the corresponding screen body 10; the second magnet device 30 includes a second magnet 31; when the folding screen 100 is in the closed state, the second magnet 31 and the first magnet 21 attract each other, causing the magnetic pole distribution direction of the first magnet 21 to change from the first direction to the second direction; when the folding screen 100 is in the open state, the reset structure 50 drives the first magnet 21 to rotate, so that the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the first direction, thereby reducing the magnetic force on the surface of the screen body 10 where the first magnet 21 is located.

[0032] For ease of expression, Figure 4 and Figure 6 The dashed boxes in the image represent the magnified first magnet device 20 and second magnet device 30. Figures 2 to 4 , Figure 6 , Figure 7 and Figure 9 The solid arrows in the diagram represent magnetic field lines.

[0033] In the usage of this embodiment, since the two screens 10 of the foldable screen 100 are connected by two first ends that rotate relative to each other, the two screens 10 can rotate relative to each other, realizing the folding and unfolding process of the foldable screen 100. When folded, the foldable screen 100 is in a closed state; when unfolded, it is in an open state, ensuring the normal use of the foldable screen 100. It can be understood that the foldable screen 100 being in a closed state includes the case where the foldable screen 100 is completely closed, that is, the two screens 10 are completely folded and in close contact, with the screens 11 of the two screens 10 touching. The foldable screen 100 being in a closed state also includes the case where the foldable screen 100 is about to be closed, that is, the two screens 10 are folded to the point where the screens 11 are about to touch, with a certain distance between the two screens 10, sufficient for the second magnet 31 and the first magnet 21 to attract each other. The foldable screen 100 being in an open state includes the case where the foldable screen 100 is completely open, that is, the two screens 10 are completely rotated and unfolded flat. The folding screen 100 being in the open state also includes situations where the folding screen 100 is slightly open, half open, or not fully unfolded. That is, when the two screens 10 are rotated to open and exit the closed state, the first magnet 21 and the second magnet 31 will not attract each other.

[0034] In this embodiment of the application, a first magnet device 20 and a second magnet device 30 are respectively installed in the two screen bodies 10 of the folding screen 100. The first magnet device 20 includes a first magnet 21 and a reset structure 50. The first magnet 21 is rotatably installed in the corresponding screen body 10. The second magnet device 30 includes a second magnet 31. When the folding screen 100 is in the closed state, the first magnet 21 and the second magnet 31 attract each other, causing the magnetic pole distribution direction of the first magnet 21 to change, specifically from the first direction to the second direction. The two screen bodies 10 remain in close contact under the action of the attraction. The reset structure 50 is configured to rotate the first magnet 21 when the folding screen 100 is in the open state, so that the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the first direction, thereby reducing the magnetic force on the surface of the screen body 10 where the first magnet 21 is located. This reduces the adsorption effect on ferromagnetic foreign objects attached to the surface of the screen body 10 where the first magnet 21 is located. In other words, it makes it difficult for ferromagnetic foreign objects to be adsorbed onto the screen 11 of the screen body 10 before the folding screen 100 is folded, preventing the folding screen 100 from trapping ferromagnetic foreign objects when it is closed. This eliminates the risk of ferromagnetic foreign objects squeezing the screen 11, avoids the appearance of colored bright spots or black spots on the screen 11, and thus improves product quality and user experience.

[0035] It should be noted that when the two screens 10 of the foldable screen 100 are folded, they can be arranged in a stacked configuration. The screen 10 with the first magnet device 20 installed can be the lower screen 10, and the screen 10 with the second magnet device 30 installed can be the upper screen 10. When the foldable screen 100 is in the open state, the magnetic force on the surface of the lower screen 10 where the first magnet 21 is located is low, so it will not attract ferromagnetic foreign objects. When the upper screen 10 is closed, the screen 11 faces downwards, and foreign objects will fall off, so it will not attract ferromagnetic foreign objects either. This prevents the foldable screen 100 from trapping ferromagnetic foreign objects when it is closed.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment, the first magnet 21 is rotatably mounted inside the screen body 10 via a rotating shaft 40, so that the magnetic pole distribution direction of the first magnet 21 changes between the first direction and the second direction; the reset structure 50 is a magnetic component, which can attract the first magnet 21 to drive the first magnet 21 to rotate, so that the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the first direction.

[0037] The first magnet 21 can rotate around the pivot 40, changing the direction of its magnetic pole distribution. Specifically, the magnetic pole distribution direction of the first magnet 21 changes between a first direction and a second direction. The reset structure 50 is a magnetic component with magnetic attraction. When the folding screen 100 is in the open state, the magnetic component attracts the first magnet 21, causing it to rotate and changing its magnetic pole distribution direction from the second direction to the first direction. This reduces the magnetic force on the surface of the screen 10 where the first magnet 21 is located, thereby reducing the attraction of ferromagnetic foreign objects attached to the surface of the screen 10 where the first magnet 21 is located. By setting the reset structure 50 as a magnetic component, and utilizing the magnetic attraction force of the magnetic component to make the first magnet 21 rotate, the structural design is reasonable and simple.

[0038] In one embodiment, the magnetic component is a magnetic frame 51 surrounding the first magnet 21. The magnetic frame 51 is fixed inside the screen body 10, and an opening 52 is formed on the side of the magnetic frame 51 facing the screen 11 of the screen body 10. The first magnet 21 is rotatably mounted inside the magnetic frame 51 via a rotating shaft 40, and the magnetic frame 51 can guide the magnetic lines of force of the first magnet 21.

[0039] The first magnet 21 can be a spherical magnet, a bar magnet, or a magnet of other shapes. In this embodiment, a spherical magnet is used as an example. The first magnet 21 is rotatably mounted on the magnetic frame 51 via a pivot 40. Specifically, the pivot 40 is rotatably connected to the inner wall of the magnetic frame 51. The magnetic frame 51 can guide the magnetic lines of force of the first magnet 21, thereby causing the first magnet 21 to rotate and change direction when the folding screen 100 is in the open state. This changes the magnetic pole distribution direction of the first magnet 21 from the second direction to the first direction, thereby reducing the magnetic force on the surface of the screen 10 where the first magnet 21 is located. The magnetic frame 51 has an opening 52 facing the screen 11 of the screen 10, so that the mutual attraction between the second magnet 31 and the first magnet 21 is not affected when the folding screen 100 is in the closed state.

[0040] In one embodiment, the magnetic frame 51 includes a first magnetically conductive wall 511, a second magnetically conductive wall 512, and a third magnetically conductive wall 513. The first magnetically conductive wall 511 and the third magnetically conductive wall 513 are disposed opposite to each other, and one end of the first magnetically conductive wall 511 and one end of the third magnetically conductive wall 513 are connected through the second magnetically conductive wall 512. The other ends of the first magnetically conductive wall 511 and the third magnetically conductive wall 513 form an opening 52. In one embodiment, as... Figure 3 As shown in (3), the first magnetic wall 511 and the third magnetic wall 513 are arranged opposite each other from left to right, and the opening 52 and the second magnetic wall 512 are arranged opposite each other from top to bottom.

[0041] like Figure 3 Neutralize (3) Figure 4 As shown, when the magnetic pole distribution direction of the first magnet 21 is the first direction, the first magnetic guide wall 511 and the third magnetic guide wall 513 guide the magnetic field lines of the first magnet 21 in opposite directions. The magnetic field lines emitted from the N pole of the first magnet 21 are guided to the S pole of the first magnet 21 in sequence through the first magnetic guide wall 511, the second magnetic guide wall 512 and the third magnetic guide wall 513 to form a closed loop of magnetic field lines. This achieves the guidance of the magnetic field lines of the first magnet 21, thereby driving the first magnet 21 to rotate and change direction when the folding screen 100 is in the open state. This causes the magnetic pole distribution direction of the first magnet 21 to change from the second direction to the first direction, greatly reducing the magnetic field lines emitted from the N pole of the first magnet 21 that wind around to the S pole through the air, thereby reducing the magnetic force on the surface of the screen 10 where the first magnet 21 is located.

[0042] like Figure 3 Zhong (4) and Figure 4As shown, when the magnetic pole distribution direction of the first magnet 21 is the second direction, the first magnetically conductive wall 511 and the third magnetically conductive wall 513 guide the magnetic field lines of the first magnet 21 in the same direction. The magnetic field lines emanating from the N pole of the first magnet 21 are guided in the same direction through the first magnetically conductive wall 511 and the third magnetically conductive wall 513 to the second magnetically conductive wall 512, and then guided in the opposite direction through the second magnetically conductive wall 512 to the S pole of the first magnet 21; or, the magnetic field lines emanating from the N pole of the first magnet 21 are guided in the opposite direction through the second magnetically conductive wall 512 to the first magnetically conductive wall 511 and the third magnetically conductive wall 513, and then guided in the same direction through the first magnetically conductive wall 511 and the third magnetically conductive wall 513 to the S pole of the first magnet 21. Thus, when the folding screen 100 is in the closed state, the opposite magnetic poles of the second magnet 31 and the first magnet 21 attract each other, and the magnetic lines of force through the magnetic frames 51 of the two screen bodies 10 will also cause the magnetic pole distribution direction of the first magnet 21 to change from the first direction to the second direction.

[0043] like Figure 5 As shown, in another embodiment, the first magnet 21 is rotatably mounted inside the screen body 10 via a rotating shaft 40, so that the magnetic pole distribution direction of the first magnet 21 changes between the first direction and the second direction; the reset structure 50 is an elastic traction member 52, which is distributed along the first direction on one side of the first magnet 21, and the first connecting end of the elastic traction member 52 is connected to the first magnet 21, and the second connecting end of the elastic traction member 52 is connected to the screen body 10; the elastic traction member 52 can deform when the folding screen 100 is in the closed state, and the elastic traction member 52 can pull the first magnet 21 to rotate through the elastic restoring force when the folding screen 100 is in the open state, so that the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the first direction.

[0044] The first magnet 21 can rotate around the pivot 40, thereby changing the direction of its magnetic pole distribution. Specifically, the direction of the magnetic pole distribution of the first magnet 21 changes between a first direction and a second direction. The reset structure 50 is an elastic traction member 52 with elasticity. The elastic traction member 52 is distributed along the first direction on one side of the first magnet 21, and the first and second connecting ends of the elastic traction member 52 are respectively connected to the first magnet 21 and the screen body 10. When the folding screen 100 is in the closed state, the second magnet 31 and the first magnet 21 attract each other, causing the first magnet 21 to rotate and change its magnetic pole distribution direction from the first direction to the second direction. The elastic traction member 52 deforms due to the rotation of the first magnet 21. When the folding screen 100 is in the open state, the second magnet 31 and the first magnet 21 lose their attraction. The elastic traction member 52 then pulls the first magnet 21 to rotate under the elastic restoring force, causing the magnetic pole distribution direction of the first magnet 21 to change from the second direction to the first direction. This reduces the magnetic force on the surface of the screen 10 where the first magnet 21 is located, thereby reducing the adsorption effect on ferromagnetic foreign objects attached to the surface of the screen 10 where the first magnet 21 is located. By setting the reset structure 50 as the elastic traction member 52, the first magnet 21 is rotated by the elastic traction force of the elastic traction member 52. The structural design is reasonable and simple.

[0045] In one embodiment, a fixing seat 53 is provided inside the screen body 10 at the position corresponding to the first magnet 21. The fixing seat 53 is fixed inside the screen body 10. The first magnet 21 is rotatably mounted on the fixing seat 53 through a rotating shaft 40. A connecting boss 54 is provided on one side of the fixing seat 53 along the first direction. The second connecting end of the elastic traction member 52 is connected to the connecting boss 54.

[0046] like Figure 5 As shown, the fixing base 53 is fixed inside the screen body 10, and the first magnet 21 is rotatably mounted on the fixing base 53 via the rotating shaft 40. To facilitate assembly with the elastic traction member 52, the fixing base 53 is provided with a connecting boss 54 on one side along the first direction, and the second connecting end of the elastic traction member 52 is connected to the connecting boss 54. In one embodiment, the elastic traction member 52 is a spring, which is easy to source and assemble.

[0047] The first magnet 21 can be a spherical magnet, a bar magnet, or a magnet of other shapes. In this embodiment, a bar magnet is used as an example. When the first magnet 21 is a bar magnet, the first connecting end of the elastic traction member 52 is connected to or near the end of the first magnet 21. Furthermore, to avoid interference between the first magnet 21 and the elastic traction member 52 during rotation, the first connecting end of the elastic traction member 52 can be connected to the side surface of the first magnet 21, while the second connecting end of the elastic traction member 52 is connected to the connecting boss 54, resulting in a reasonable structural design.

[0048] The first magnet 21 has a large swing amplitude at its end or near the end when it rotates, which can cause the elastic traction member 52 connected to it to deform more and have a greater elastic restoring force. Thus, when the folding screen 100 is in the open state, the elastic restoring force pulls the first magnet 21 to rotate and change direction quickly.

[0049] In one embodiment, the first direction is the direction from the N pole to the S pole of the first magnet 21 that is perpendicular or substantially perpendicular to the thickness direction of the screen 10; the second direction is the direction from the N pole to the S pole of the first magnet 21 that is parallel or substantially parallel to the thickness direction of the screen 10.

[0050] Understandably, such as Figure 4 As shown in Figure (5), the thickness direction of the screen body 10 is vertical, i.e., up and down. The first direction is the direction from the N pole to the S pole of the first magnet 21, which is perpendicular or substantially perpendicular to the thickness direction of the screen body 10. Figure 4 The directions that are perpendicular or substantially perpendicular to each other in the middle (5), that is, the first direction is Figure 4 The second direction is the horizontal or substantially horizontal direction shown in (5). The direction from the N pole to the S pole of the first magnet 21 is parallel or substantially parallel to the thickness direction of the screen 10, that is, the second direction is parallel to the thickness direction of the screen 10. Figure 4 The vertical directions of (5) are parallel or substantially parallel to each other, that is, the second direction is Figure 4 The vertical direction or substantially vertical direction shown in (5). This embodiment is illustrated using the first direction as the horizontal direction and the second direction as the vertical direction as an example.

[0051] When the folding screen 100 is in the closed state, the second magnet 31 and the first magnet 21 attract each other. Under the attraction of the second magnet 31, the first magnet 21 rotates, thereby changing the magnetic pole distribution direction of the first magnet 21 from the horizontal direction to the vertical direction. The opposite magnetic poles of the second magnet 31 and the first magnet 21 attract each other, and the attraction between the first magnet 21 and the second magnet 31, whose magnetic poles are vertically distributed, is stronger. When the folding screen 100 is in the open state, the reset structure 50 drives the first magnet 21 to rotate, changing the magnetic pole distribution direction of the first magnet 21 from the vertical direction to the horizontal direction, thereby maximizing or even eliminating the magnetic force on the surface of the screen 10 where the first magnet 21 is located.

[0052] In other embodiments, the first direction may be any other direction that can reduce the magnetic force on the surface of the screen 10 where the first magnet 21 is located, and the second direction may be any other direction that facilitates the attraction between the second magnet 31 and the first magnet 21.

[0053] like Figures 3 to 5As shown, in one embodiment, the structure of the second magnet device 30 is consistent with the structure of the first magnet device 20, and the second magnet 31 is the first magnet 21. It should be noted that the fact that the structure of the second magnet device 30 is consistent with the structure of the first magnet device 20, and that the second magnet 31 is the first magnet 21, indicates that the second magnet device 30 also includes the first magnet 21 and the reset structure 50. Furthermore, the positional relationship, connection relationship, and operational relationship between the first magnet 21 and the reset structure 50 in the second magnet device 30 are consistent with those in the first magnet device 20. In other words, the second magnet 31 in the second magnet device 30 is the same as the first magnet 21; that is, the second magnet 31 and the first magnet 21 in the second magnet device 30 are the same magnet.

[0054] In this application, the same magnet in the second magnet device 30 is referred to as the first magnet 21 and the second magnet 31 only to distinguish it from the first magnet 21 in the first magnet device 20. When the second magnet device 30 and the first magnet device 20 have the same structure, the first magnet device 20 and the second magnet device 30 are magnet devices installed in two different screen bodies 10, and the magnet devices are referred to as the second magnet device 30 and the first magnet device 20 only to distinguish them.

[0055] The structure of the second magnet device 30 is the same as that of the first magnet device 20. The second magnet 31 in the second magnet device 30 is the same magnet as the first magnet 21, and both are rotatable movable magnets. The second magnet 31 will be referred to as the first magnet 21 below.

[0056] like Figure 3 and Figure 4 As shown, when the folding screen 100 is in the closed state, the first magnets 21 in the two screen bodies 10 attract each other, causing the magnetic pole distribution direction of each first magnet 21 to change from the first direction to the second direction, and the two screen bodies 10 remain in close contact under the action of the attraction. When the folding screen 100 is in the open state, the reset structure 50 in each screen body 10 drives the first magnet 21 to rotate, causing the magnetic pole distribution direction of the first magnet 21 to change from the second direction to the first direction, reducing the magnetic force on the surface of each screen body 10.

[0057] A first magnet device 20 and a second magnet device 30 with identical structures are respectively set in the two screen bodies 10 of the foldable screen 100. Whether it is the upper screen body 10 or the lower screen body 10, when the foldable screen 100 is in the open state, the surface magnetism of the upper screen body 10 and the lower screen body 10 will be reduced, and neither the upper screen body 10 nor the lower screen body 10 will attract foreign objects. The upper screen body 10 and the lower screen body 10 can be indistinguishable in terms of top and bottom during the closing process. The upper screen body 10 can be located above the lower screen body 10, or the positions of the upper screen body 10 and the lower screen body 10 can be interchanged, so that the upper screen body 10 is located below the lower screen body 10, which provides high flexibility of use.

[0058] like Figure 6 As shown, in other embodiments, the second magnet 31 is a fixed magnet, and the magnetic pole distribution direction of the fixed magnet is the second direction. When the second magnet 31 is a fixed magnet, its magnetic pole distribution direction remains unchanged. Regardless of whether the folding screen 100 is in the open or closed state, the magnetic pole distribution direction of the second magnet 31 is always the second direction, that is, always in the vertical direction. Thus, when the folding screen 100 is in the closed state, the second magnet 31 can quickly attract the first magnet 21 to turn, causing the magnetic pole distribution direction of the first magnet 21 to quickly change from the first direction to the second direction, achieving close contact between the two screens 10. When the folding screen 100 is in the open state, the second magnet 31, due to the greater distance from the first magnet 21, loses its attraction to the first magnet 21. Under the action of the reset structure 50, the first magnet 21 turns, causing its magnetic pole distribution direction to change from the second direction to the first direction.

[0059] In this embodiment, the second magnet 31 is set as a fixed magnet, while the first magnet 21 is a rotatable movable magnet. As long as the first magnet 21 changes direction, the second magnet 31 remains stationary. The second magnet device 30 does not need to be equipped with a reset structure 50, which simplifies the structure and makes it easier to manufacture.

[0060] When the second magnet 31 is a fixed magnet, the fixed magnet can be set on the upper screen body 10, and the first magnet 21 can be set on the lower screen body 10. With this setting, when the folding screen 100 is in the open state, the magnetic force on the surface of the lower screen body 10 where the first magnet 21 is located is low and will not attract ferromagnetic foreign objects. When the upper screen body 10 is closed, the screen 11 is facing down, and foreign objects will fall off and will not attract ferromagnetic foreign objects, thereby preventing the folding screen 100 from trapping ferromagnetic foreign objects when it is closed.

[0061] like Figure 8As shown, in another embodiment, the first magnet 21 is rotatably mounted inside the screen body 10 via a rotating shaft 40, so that the magnetic pole distribution direction of the first magnet 21 changes between a first direction and a second direction; the reset structure 50 includes a processing module 55 and a trigger module 56, a sensing module 57 and a drive mechanism 58 communicatively connected to the processing module 55. The sensing module 57 is configured to sense the state of the folding screen 100, which includes an open state and a closed state; the drive mechanism 58 is connected to the rotating shaft 40; when the trigger module 56 senses a trigger signal, it sends the trigger signal to the processing module 55. The processing module 55 is configured to control the drive mechanism 58 to drive the rotating shaft 40 to rotate according to the trigger signal and when the sensing module 57 senses that the folding screen 100 is in a closed state, so as to drive the first magnet 21 to rotate, so that the magnetic pole distribution direction of the first magnet 21 changes from the second direction to a third direction, so that the folding screen 100 switches from a closed state to an open state under the interaction of the first magnet 21 and the second magnet 31.

[0062] The first magnet 21 can rotate around the pivot 40, thereby changing the direction of its magnetic pole distribution. Specifically, the direction of the magnetic pole distribution of the first magnet 21 can be changed between a first direction and a second direction. The reset structure 50 consists of a processing module 55, a trigger module 56, a sensing module 57, and a drive mechanism 58. The trigger module 56, the sensing module 57, and the drive mechanism 58 are all communicatively connected to the processing module 55.

[0063] The sensing module 57 is configured to sense the state of the foldable screen 100, which includes an open state and a closed state. As mentioned earlier, the closed state includes the case where the foldable screen 100 is fully closed, that is, the two screens 10 are fully folded and in close contact, with the screens 11 of the two screens 10 touching. The closed state also includes the case where the foldable screen 100 is about to be closed, that is, the two screens 10 are folded to the point where the screens 11 are about to touch, with a certain distance between the two screens 10, sufficient for the second magnet 31 and the first magnet 21 to attract each other. The open state includes the case where the foldable screen 100 is fully open, that is, the two screens 10 are fully rotated and unfolded. The folding screen 100 being in the open state also includes situations where the folding screen 100 is slightly open, half open, or not fully unfolded. That is, when the two screens 10 are rotated to open and exit the closed state, the first magnet 21 and the second magnet 31 will not attract each other.

[0064] When the trigger module 56 senses a trigger signal, it sends the trigger signal to the processing module 55. When the processing module 55 receives the sensing signal and the sensing module 57 senses that the foldable screen 100 is in the closed state, the processing module 55 controls the drive mechanism 58 to drive the rotating shaft 40 to rotate, thereby causing the first magnet 21 to rotate and change direction. Specifically, the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the third direction. When the magnetic pole distribution direction of the first magnet 21 is in the third direction, the foldable screen 100 can switch from the closed state to the open state under the interaction of the first magnet 21 and the second magnet 31. That is, due to the interaction of the first magnet 21 and the second magnet 31, the two screens 10 can be pushed to rotate in opposite directions to open, which plays an auxiliary role when the user opens the foldable screen 100, saving time and effort.

[0065] like Figure 9 As shown, in one embodiment, due to the interaction between the first magnet 21 and the second magnet 31, the two screen bodies 10 can be pushed to rotate in opposite directions, causing the folding screen 100 to open to a slightly open state. It should be noted that when the folding screen 100 is opened to the slightly open state, the screens 11 of the two screen bodies 10 are very close together, and the ferromagnetic material 200 will not fall onto the surface of the screens 11 of the screen bodies 10. Even if the ferromagnetic material 200 might fall onto the surface of the screens 11 of the screen bodies 10 when the folding screen 100 is opened to the slightly open state, because the magnetic pole distribution direction of the first magnet 21 changes from the second direction to the third direction, the ferromagnetic material 200 attached to the surface of the screen body 10 where the first magnet 21 is located can lie flat on the screen body 10, preventing the tips of the ferromagnetic material 200 from pointing towards the screen 11, thereby preventing the ferromagnetic material 200 from damaging the screen 11.

[0066] The trigger module 56 is a fingerprint recognition module, button, or switch located on one side of the screen 10. When the user needs to open the foldable screen 100, they can sense the trigger signal by touching the fingerprint recognition module or pressing the button or switch, which is simple and convenient. The sensing module 57 includes a Hall sensor configured to sense the state of the foldable screen 100. The Hall sensor has advantages such as high sensitivity, fast response, high measurement accuracy, high stability, and low power consumption.

[0067] In one embodiment, the drive mechanism 58 includes a drive member and a transmission assembly. The drive member is communicatively connected to the processing module 55, and the transmission assembly is connected between the drive member and the rotating shaft 40. The drive member is configured to drive the rotating shaft 40 to rotate via the transmission assembly. Further, the drive member is a rotary drive member, and the transmission assembly includes a driving gear and a driven gear. The driving gear is connected to the drive member, and the driving gear meshes with the driven gear. The driven gear is sleeved on the rotating shaft 40. Specifically, the rotary drive member can be a motor. The motor drives the driving gear to rotate, thereby driving the driven gear to rotate. The driven gear is connected to the rotating shaft 40, and the driven gear drives the rotating shaft 40 to rotate, which in turn drives the first magnet 21 to rotate via the rotating shaft 40. The motor is communicatively connected to the processing module 55, which can control the motor's start / stop and rotation speed, etc.

[0068] In other embodiments, other drive mechanisms 58 that can drive the rotating shaft 40 to rotate, such as a drive mechanism 58 consisting of a motor, a drive sprocket, a chain, and a driven sprocket, or a drive mechanism 58 consisting of a motor, a synchronous pulley, and a synchronous belt, may also be used.

[0069] In one embodiment, the processing module 55 is further configured to control the drive mechanism 58 to drive the rotating shaft 40 to rotate when the sensing module 57 senses that the folding screen 100 is in an open state, so as to drive the first magnet 21 to rotate and change the magnetic pole distribution direction of the first magnet 21 from a third direction to a first direction.

[0070] After switching from the closed state to the open state, the sensing module 57 senses that the foldable screen 100 is in the open state. The processing module 55 controls the driving mechanism 58 to drive the rotating shaft 40 to rotate, which drives the first magnet 21 to rotate until its magnetic pole distribution direction changes from the third direction to the first direction, so as to reduce the magnetic force on the surface of the screen 10 where the first magnet 21 is located. The design is reasonable and ingenious.

[0071] In one embodiment, the processing module 55 is further configured to control the drive mechanism 58 to drive the rotating shaft 40 to rotate when the sensing module 57 senses that the folding screen 100 is in a closed state, so as to drive the first magnet 21 to rotate, so that the magnetic pole distribution direction of the first magnet 21 changes from the first direction to the second direction, thereby realizing the mutual attraction between the second magnet 31 and the first magnet 21, and keeping the two screens 10 in close contact under the action of the attraction.

[0072] In one embodiment, the first direction is the direction from the N pole to the S pole of the first magnet 21 that is perpendicular or substantially perpendicular to the thickness direction of the screen 10; the second direction is the direction from the N pole to the S pole of the first magnet 21 that is parallel or substantially parallel to the thickness direction of the screen 10; and the third direction is opposite to the second direction.

[0073] Understandably, such as Figure 4As shown in Figure (5), the thickness direction of the screen body 10 is vertical, i.e., up and down. The first direction is the direction from the N pole to the S pole of the first magnet 21, which is perpendicular or substantially perpendicular to the thickness direction of the screen body 10. Figure 4 The directions that are perpendicular or substantially perpendicular to each other in the middle (5), that is, the first direction is Figure 4 The second direction is the horizontal or substantially horizontal direction shown in (5). The direction from the N pole to the S pole of the first magnet 21 is parallel or substantially parallel to the thickness direction of the screen 10, that is, the second direction is parallel to the thickness direction of the screen 10. Figure 4 In (5), the vertical directions are parallel or substantially parallel to each other, that is, the second direction is Figure 4 The vertical or substantially vertical direction shown in (5). The third direction is the direction from the N pole to the S pole of the first magnet 21 that is parallel or substantially parallel to the thickness direction of the screen 10, that is, the third direction is parallel to the thickness direction of the screen 10. Figure 4 The vertical directions of (5) are parallel or substantially parallel to each other, that is, the third direction is Figure 4 The vertical direction or substantially vertical direction shown in (5) is such that the third direction is opposite to the second direction, and the direction from the N pole to the S pole of the third direction is opposite to the direction from the N pole to the S pole of the second direction. This embodiment is illustrated by taking the first direction as the horizontal direction, and the second and third directions as vertical directions set in opposite directions.

[0074] When the trigger module 56 senses a trigger signal, it sends the trigger signal to the processing module 55. Upon receiving the sensing signal, and when the sensing module 57 senses that the foldable screen 100 is in a closed state, the processing module 55 controls the drive mechanism 58 to drive the rotating shaft 40 to rotate, thereby causing the first magnet 21 to rotate and change direction. Specifically, the magnetic pole distribution direction of the first magnet 21 changes from the second direction to a third direction. When the magnetic pole distribution direction of the first magnet 21 is the second direction, the opposite magnetic poles of the first magnet 21 and the second magnet 31 attract each other. When the magnetic pole distribution direction of the first magnet 21 is the third direction, the foldable screen 100 can switch from a closed state to an open state under the repulsive action of the like magnetic poles of the first magnet 21 and the second magnet 31.

[0075] After switching from the closed state to the open state, the sensing module 57 senses that the foldable screen 100 is in the open state. The processing module 55 controls the driving mechanism 58 to drive the rotating shaft 40 to rotate, causing the first magnet 21 to rotate until its magnetic pole distribution direction changes from a third direction to a first direction, that is, from the vertical direction to the horizontal direction, so as to reduce the magnetic force on the surface of the screen 10 where the first magnet 21 is located.

[0076] When the sensing module 57 senses that the folding screen 100 is in the closed state, the processing module 55 controls the drive mechanism 58 to drive the rotating shaft 40 to rotate, thereby causing the first magnet 21 to rotate. This changes the magnetic pole distribution direction of the first magnet 21 from the first direction to the second direction, that is, from the horizontal direction to the vertical direction. The opposite magnetic poles of the second magnet 31 and the first magnet 21 attract each other, so that the two screens 10 remain in close contact under the action of the attraction force. The attraction force between the first magnet 21 and the second magnet 31, whose magnetic poles are distributed in the vertical direction, is stronger.

[0077] In other embodiments, the first direction can be any direction that reduces the magnetic force on the surface of the screen 10 where the first magnet 21 is located, the second direction can be any direction that facilitates the attraction between the second magnet 31 and the first magnet 21, and the third direction can be any direction that facilitates the repulsion between the second magnet 31 and the first magnet 21.

[0078] In this embodiment, the structure of the second magnet device 30 is the same as that of the first magnet device 20, and the second magnet 31 is the first magnet 21. Both the first magnet 21 and the second magnet 31 are rotatable movable magnets. Alternatively, the second magnet 31 is a fixed magnet, and the magnetic pole distribution direction of the fixed magnet is the second direction.

[0079] Understandably, in this embodiment, both the first magnet 21 and the second magnet 31 are set as movable magnets, or the first magnet 21 is set as a movable magnet and the second magnet 31 is set as a fixed magnet. Except for the following differences from the interaction between the two magnet devices described above, everything else is the same, and will not be repeated here.

[0080] The embodiment described above describes the situation where, when the foldable screen 100 is in the open state, the magnetic pole distribution direction of the first magnet 21 rotates 90° from the vertical direction to the horizontal direction; when the foldable screen 100 is in the closed state, the magnetic pole distribution direction of the first magnet 21 rotates 90° from the horizontal direction to the vertical direction. However, in this embodiment, when the foldable screen 100 switches from the closed state to the open state, the magnetic pole distribution direction of the first magnet 21 rotates 180° from the vertical direction to the opposite vertical direction, causing the attraction between the opposite magnetic poles of the first magnet 21 and the second magnet 31 to change from attraction between like magnetic poles to repulsion between like magnetic poles; after switching from the closed state to the open state, the magnetic pole distribution direction of the first magnet 21 rotates 90° from the vertical direction to the horizontal direction; and when the foldable screen 100 is in the closed state, the magnetic pole distribution direction of the first magnet 21 rotates 90° from the horizontal direction back to the vertical direction.

[0081] It should be noted that when both the first magnet 21 and the second magnet 31 are set as movable magnets, to change the attraction between opposite magnetic poles of the first magnet 21 and the second magnet 31 to the repulsion between like magnetic poles, it is only necessary to rotate one of the movable magnets to change the direction.

[0082] like Figure 7 As shown, in one embodiment, one screen 10 is equipped with a plurality of first magnet devices 20, and the other screen 10 is equipped with a plurality of second magnet devices 30. The number of first magnet devices 20 and the number of second magnet devices 30 are the same, and they are arranged in a one-to-one correspondence when the folding screen 100 is in the closed state.

[0083] Specifically, multiple first magnet devices 20 can be located near the second end of the screen body 10 and can be arranged at intervals along the direction from the second end to the first end of the screen body 10 for reasonable layout and to avoid other components inside the screen body 10. By setting multiple first magnet devices 20 and multiple second magnet devices 30, the attraction between the two screen bodies 10 is increased when the folding screen 100 is in the closed state, and the directional pushing force between the two screen bodies 10 is greater when the folding screen 100 switches from the closed state to the open state, which is conducive to the folding screen 100 opening quickly and with less effort.

[0084] In one embodiment, at least one screen body 10 is provided with a telescopic member, which is configured to extend toward another screen body 10 when the folded screen 100 is in the closed state, and the telescopic member is also configured to retract to the screen body 10 where the telescopic member is located when the folded screen 100 is in the open state.

[0085] Understandably, when the foldable screen 100 is closed, the screens 11 of the two screen bodies 10 are tightly fitted together, leaving narrow gaps around the edges of the two screens 11, especially if one of the screen bodies 10 has a curved screen. To prevent debris from entering the mating surface of the two screens 11 through these narrow gaps when the foldable screen 100 is closed, at least one screen body 10 is equipped with a telescopic component. This component can extend or retract relative to its respective screen body 10. Specifically, when the foldable screen 100 is closed, it extends towards the other screen body 10 until it completely covers the narrow gaps. When the foldable screen 100 is open, the telescopic component retracts back into its respective screen body 10, without affecting the normal use of the foldable screen 100.

[0086] like Figure 10As shown, the two screens 10 are respectively provided with a first magnetic 60 and a second magnetic 70, and the telescopic component is a slider 80. The slider 80 is slidably inserted into the screen 10 where the second magnetic 70 is located. Both the first magnetic 60 and the second magnetic 70 can attract the slider 80, and the attraction of the first magnetic 60 to the slider 80 is greater than that of the second magnetic 70. When the folding screen 100 is in the closed state, the first magnetic 60 can attract the slider 80 to extend towards the screen 10 where the first magnetic 60 is located. When the folding screen 100 is in the open state, the second magnetic 70 can attract the slider 80 to retract back to the screen 10 where the slider 80 is located.

[0087] The slider 80 is positioned around the outer periphery of the screen 10 where the second magnetic member 70 is located, excluding the first end. Since the attraction of the first magnetic member 60 to the slider 80 is greater than that of the second magnetic member 70 to the slider 80, when the folding screen 100 is in the closed state, the first magnetic member 60 attracts the slider 80 to extend towards the screen 10 where the first magnetic member 60 is located until the slider 80 completely covers the narrow gap. When the folding screen 100 is in the open state, the two screens 10 are far apart from each other, the first magnetic member 60 loses its attraction to the slider 80, and the second magnetic member 70 attracts the slider 80 back to its screen 10, without affecting the normal use of the folding screen 100.

[0088] It should be noted that the first magnetic attractor 60 and the second magnetic attractor 70 will not affect the normal operation of the first magnet device 20 and the second magnet device 30 installed inside the screen 10. In one embodiment, as... Figure 10 As shown, each screen body 10 is covered with a protective shell 90. The first magnetic suction member 60 can be set on the protective shell 90 of the corresponding screen body 10, and the slider 80 can be inserted into the protective shell 90.

[0089] The folding screen 100 can be a double-folding screen 100, a triple-folding screen 100, or even a quadruple-folding screen 100 or more. In one embodiment, the folding screen 100 includes at least three screen bodies 10, all of which are sequentially hinged so that all of the screen bodies 10 can rotate relative to each other so that any two adjacent screen bodies 10 are in an open or closed state. The screen body 10 in the middle position is equipped with a first magnet device 20 and a second magnet device 30, and the screen body 10 in the outermost position is equipped with a second magnet device 30 or a first magnet device 20 respectively. This ensures that any two adjacent screen bodies 10 can operate as described above, and will not be repeated here.

[0090] This application also proposes an electronic device that uses the aforementioned foldable screen 100.

[0091] The electronic device can be a mobile phone, tablet, computer, or other electronic product that uses the foldable screen 100 described above. The specific structure and usage of the foldable screen 100 in this electronic device are as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0092] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. All equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
