Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly relates to a foldable electronic device. Background Art

[0002] The screen of a foldable mobile phone generally consists of multiple layers, and there will be a relatively large outward rebound force when the screen is in the folded state. To ensure the reliability of the folded state, in addition to setting a torsion locking structure on the rotating shaft, more than one set of magnets will also be set on the left and right or upper and lower shells, so that the two shells are held in the folded state through magnetic attraction. However, due to the existence of magnets on both shells, foldable mobile phones often attract small metal objects in daily life. If the user directly folds the phone without cleaning these metal objects before folding, it will cause the problem of the metal objects pressing and damaging the screen. Summary of the Invention

[0003] This application provides a foldable electronic device that can avoid the problem of being pressed and damaged.

[0004] The foldable electronic device includes:

[0005] A first body, the first body includes a first shell, a first magnetic member, and a first magnetic shielding assembly. The first magnetic shielding assembly includes a first magnetic shielding member and a first driving member. At least one of the first magnetic shielding member and the first magnetic member is movably connected to the first shell. The first driving member is used to drive the first magnetic shielding member and / or the first magnetic member to move, so as to change the area of the first magnetic member blocked by the first magnetic shielding member; and

[0006] A second body, the second body is rotatably connected to the first body. The first body and the second body can move towards each other to make the foldable electronic device enter the folded state, or move away from each other to make the foldable electronic device enter the unfolded state. The second body includes a second magnetic member;

[0007] When the foldable electronic device is in the folded state, the area of the first magnetic member blocked by the first magnetic shielding member is a first area, and at least part of the first magnetic member is exposed outside the first magnetic shielding member to magnetically attract the second magnetic member; when the foldable electronic device is in the unfolded state, the area of the first magnetic member blocked by the first magnetic shielding member is a second area, and the second area is larger than the first area, so as to magnetically isolate at least part of the first magnetic member from the outside through the first magnetic shielding member.

[0008] In the foldable electronic device provided by the present application, a first magnetic member, a first magnetic shielding member, and a first driving member are provided on a first body. Among them, the first driving member can drive the first magnetic shielding member and / or the first magnetic member to move, so as to change the position of the first magnetic shielding member relative to the first magnetic member. When the foldable electronic device is in the folded state, the area of the first magnetic member shielded by the first magnetic shielding member is a first area, and at least a part of the first magnetic member is exposed outside the first magnetic shielding member. The exposed part of the first magnetic member magnetically adsorbs a second magnetic member of a second body, so that the foldable electronic device can be stably maintained in the folded state; when the foldable electronic device is in the unfolded state, the area of the first magnetic member shielded by the first magnetic shielding member is a second area, and the second area is larger than the first area. At this time, the magnetic attraction ability of the first magnetic member to foreign objects outside is weakened or there is no magnetic attraction ability, so foreign objects outside will not be magnetically adsorbed to the first body by the first magnetic member.

[0009] Moreover, during the folding process of the folding device, the first magnetic shielding member and the first magnetic member will gradually move away as the included angle decreases, so that the magnetic attraction ability of the first magnetic member to the outside gradually increases as the included angle decreases. It can be understood that when the included angle is large, the magnetic attraction ability of the first magnetic member to the outside is weak, and foreign objects outside are not easily magnetically adsorbed and attached to the first body; when the included angle is small, although the magnetic attraction ability of the first magnetic member to the outside is strong, it is already difficult for foreign objects to enter the small gap between the first body and the second body. Therefore, the folding device provided by the present application can better avoid the problem of being crushed during the folding process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0041] Referring to "embodiment" or "implementation manner" herein means that the specific features, structures or characteristics described in connection with the embodiment or implementation manner may be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0042] Please refer to Figures 1 to 3 , the present application provides a foldable electronic device 100, which refers to a device that can change its own form by bending, rotating, etc. The foldable electronic device 100 may be a display device, such as a folding screen mobile phone, a tablet computer, a notebook computer, an e-book, a display, a handheld game console, etc. The foldable electronic device 100 may also be a non-display device, such as a graphics tablet, a keyboard, etc. The following content of the present application will take a folding screen mobile phone as an example for specific description, and this example should not be regarded as a limitation to the present application.

[0043] The foldable electronic device 100 includes: a first body 10 and a second body 20, and the second body 20 is rotatably connected to the first body 10. The foldable electronic device 100 has an unfolded state (as Figure 1 shown) and a folded state (as Figure 2 shown). The first body 10 and the second body 20 can move towards each other to enter the folded state or move away from each other to enter the unfolded state. In different states of the foldable electronic device 100, the included angle α formed by the first body 10 and the second body 20 is different.

[0044] When the foldable electronic device 100 is in the unfolded state, the included angle α formed by the first body 10 and the second body 20 is the largest (here, the included angle α corresponding to the unfolded state is simply referred to as the first included angle), and the first included angle can be but is not limited to 180°. When the foldable electronic device 100 is in the folded state, the included angle α formed by the first body 10 and the second body 20 is the smallest (here, the included angle α corresponding to the folded state is simply referred to as the second included angle), and the second included angle can be but is not limited to 0°. The foldable electronic device 100 can also have one or more intermediate hovering states (as Figure 3 shown). When the foldable electronic device 100 is in the intermediate hovering state, the included angle α formed by the first body 10 and the second body 20 is between the first included angle and the second included angle, and at this time, the foldable electronic device 100 is generally in a V-shaped form. It should be noted that the description of "included angle α" involved in the following content refers to the angle formed by the first body 10 and the second body 20.

[0045] Under different usage requirement conditions, the user can fold and unfold the foldable electronic device 100 to meet different scenario requirements. For example, when the user is using the foldable electronic device 100, it can be unfolded to form an unfolded state, so as to provide a larger operable area and improve the usage experience, as Figure 1 shown; when the user needs to carry the foldable electronic device 100 with them, it can be folded to form a folded state, so as to reduce its volume and improve portability, as Figure 2 shown.

[0046] Please refer to Figure 1 and Figure 4, taking a foldable mobile phone as an example, the foldable electronic device 100 further includes a flexible screen 40, and the flexible screen 40 can be a flexible organic light-emitting diode (OLED) display screen. The flexible screen 40 includes a first non-bending display area 41, a bending display area 43, and a second non-bending display area 42 that are arranged in sequence and can display images. Among them, the first non-bending display area 41 of the flexible screen 40 is connected to the first body 10, and the second non-bending display area 42 of the flexible screen 40 is connected to the second body 20. When the flexible screen 40 switches between the unfolded state, the folded state, and the intermediate hovering state, the first non-bending display area 41 and the second non-bending display area 42 do not bend. The bending display area 43 is flattened when the flexible screen 40 is in the unfolded state, and the bending display area 43 bends when the flexible screen 40 is in the folded state, the intermediate hovering state, and during the process of switching between various states. Optionally, when the flexible screen 40 is in the folded state, the bending display area 43 can be bent in a water droplet shape. It can be understood that when the foldable mobile phone is unfolded, the flexible screen 40 can provide a large display area and an operation area. When the foldable mobile phone is folded, the flexible screen 40 can be wrapped between the first housing 11 and the second housing 21 to provide good protection for the flexible screen 40.

[0047] The foldable electronic device 100 can be folded up and down or left and right. The folding type of the foldable electronic device 100 can be an inward fold or an outward fold. In some embodiments, it can also have both inward and outward folds, that is, the foldable device can be both inwardly folded and outwardly folded. Among them, "inward fold" means that the side of the foldable electronic device 100 that allows users to operate and interact is folded inside, and the opposite side is folded outside; similarly, "outward fold" means that the side of the foldable electronic device 100 that allows users to operate and interact is folded outside, and the opposite side is folded inside. Taking a foldable mobile phone as an example, "inward fold" means that the flexible screen 40 of the foldable mobile phone is folded in a face-to-face (the first non-bending display area 41 and the second non-bending display area 42 are opposite) form; "outward fold" means that the flexible screen 40 of the foldable mobile phone is folded in a back-to-back (the first non-bending display area 41 and the second non-bending display area 42 are back-to-back) form. The following content of this application is exemplarily described based on the inward fold.

[0048] In the related art, magnets are provided inside both the first body 10 and the second body 20. When the foldable electronic device 100 is in the folded state, the first non-bending display area 41 and the second non-bending display area 42 are folded together relatively (in the form of inward folding), and the magnets on the first body 10 and the magnets on the second body 20 attract each other to stably maintain the foldable electronic device 100 in the folded state. It can be understood that magnets always have the ability to adsorb ferromagnetic substances. In the unfolded state, if magnetic isolation is not applied to the magnets, then, it is very likely that some external ferromagnetic foreign objects (such as metal screws) will be adsorbed on the first non-bending display area 41 or the second non-bending display area 42 of the foldable electronic device 100. If the user does not notice these foreign objects and directly folds the foldable electronic device 100, it is very likely that marks will be pressed out on the first non-bending display area 41 and the second non-bending display area 42, and even problems such as cracking (crushing problems) will occur.

[0049] Based on this, the present application proposes a solution to solve the above-mentioned crushing problem by providing a magnetic isolation member on the foldable electronic device 100, which will be introduced below in combination with the magnetic isolation member.

[0050] Please refer to Figures 5 to 6 , the first body 10 includes a first housing 11, a first magnetic member 13 (see Figure 6 ), and a first magnetic isolation assembly 12. The first magnetic isolation assembly 12 includes a first magnetic isolation member 122 and a first driving member 123. At least one of the first magnetic isolation member 122 and the first magnetic member 13 is movably connected to the first housing 11. The first driving member 123 is connected to the first magnetic isolation member 122 and / or the first magnetic member 13, and is used to drive the first magnetic isolation member 122 to move and / or drive the first magnetic member 13 to move, so as to change the area of the first magnetic member 13 blocked by the first magnetic isolation member 122. It should be noted that whether the first driving member 123 drives the first magnetic isolation member 122 or the first magnetic member 13, in essence, it is the relative position of the first magnetic isolation member 122 and the first magnetic member 13 that changes, so that the area of the first magnetic member 13 blocked by the first magnetic isolation member 122 changes. That is to say, although the objects driven by the first driving member 123 are different, the achieved result is that the blocked area changes. Therefore, in the related drawings of the present application, only the example of "the first driving member 123 drives the first magnetic isolation member 122" is used for illustration. Since the principle of "the first driving member 123 drives the first magnetic member 13" is the same as that of "the first driving member 123 drives the first magnetic isolation member 122", no further drawing display and description will be provided.

[0051] Among them, the first housing 11 is a structure that plays a role in carrying and protecting various electronic devices, mechanical components, etc. in the first body 10. The general shape of the first housing 11 can be but is not limited to a rectangular frame. When the foldable electronic device 100 is a folding screen mobile phone, the first housing 11 can be a part of the middle frame.

[0052] Among them, the first magnetic member 13 (such as a magnet) is a magnetic object that can generate a magnetic field and attract ferromagnetic substances (such as iron, nickel, cobalt, etc.). The shape of the first magnetic member 13 can be bar-shaped, square, horseshoe-shaped, ring-shaped, etc. The first magnetic member 13 is installed on the first housing 11, and it can be movably connected to the first housing 11 (i.e., it can move relative to the first housing 11), or it can be fixedly connected to the first housing 11. When the first magnetic member 13 is fixedly connected to the first housing 11, the connection method between the first magnetic member 13 and the first housing 11 can be, but is not limited to, bonding, detachable clamping, etc. For example, the first housing 11 is provided with a receiving groove, and the first magnetic member 13 is arranged in the receiving groove and bonded to the first housing 11 through glue.

[0053] Among them, the first magnetic shielding member 122 is an object that can isolate the magnetic field. For example, when a magnetic shielding member is placed between two mutually attracting magnets, if the two magnets are completely separated, the two magnets will no longer attract each other magnetically. If they are partially separated, the magnetic attraction between the two magnets will be weakened. The first magnetic shielding member 122 is installed on the first housing 11, and it can be movably connected to the first housing 11 (i.e., it can move relative to the first housing 11), or it can be fixedly connected to the first housing 11. When the first magnetic shielding member 122 is fixedly connected to the first housing 11, the connection method between the first magnetic shielding member 122 and the first housing 11 can be, but is not limited to, bonding, detachable clamping, etc. The shape of the first magnetic shielding member 122 can be, but is not limited to, rectangular, circular, oval, or irregular special-shaped, etc.

[0054] Among them, the first driving member 123 is connected to at least one of the first magnetic shielding member 122 and the first magnetic member 13. When the first magnetic shielding member 122 is movably connected to the first housing 11, the first driving member 123 is connected to the first magnetic shielding member 122 to drive the first magnetic shielding member 122 to move. When the first magnetic member 13 is movably connected to the first housing 11, the first driving member 123 is connected to the first magnetic member 13 to drive the first magnetic member 13 to move. The first driving member 123 is used to change the relative position between the first magnetic shielding member 122 and the first magnetic member 13, so that the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 is changed. The first driving member 123 is installed on the first housing 11, and it can be movably connected to the first housing 11 (i.e., it can move relative to the first housing 11), or it can be fixedly connected to the first housing 11. When the first driving member 123 is fixedly connected to the first housing 11, the connection method between the first driving member 123 and the first housing 11 can be, but is not limited to, bonding, detachable clamping, etc.

[0055] In one embodiment, the first magnetic member 13 is movably connected to the first housing 11, and the first magnetic shielding member 122 can be fixedly connected to the first housing 11. The first driving member 123 is configured to drive the first magnetic member 13 to move relative to the first magnetic shielding member 122, so that the first magnetic member 13 and the first magnetic shielding member 122 approach or move away from each other, thereby changing the area of the first magnetic member 13 blocked by the first magnetic shielding member 122.

[0056] In another embodiment, the first magnetic shielding member 122 is movably connected to the first housing 11, and the first magnetic member 13 can be fixedly connected to the first housing 11. The first driving member 123 is configured to drive the first magnetic shielding member 122 to move relative to the first magnetic member 13, so that the first magnetic member 13 and the first magnetic shielding member 122 approach or move away from each other, thereby changing the area of the first magnetic member 13 blocked by the first magnetic shielding member 122.

[0057] In yet another embodiment, both the first magnetic member 13 and the first magnetic shielding member 122 are movably connected to the first housing 11. The first driving member 123 is configured to drive the first magnetic member 13 to move relative to the first magnetic shielding member 122 and drive the first magnetic shielding member 122 to move relative to the first magnetic member 13, so that the first magnetic member 13 and the first magnetic shielding member 122 approach or move away from each other, thereby changing the area of the first magnetic member 13 blocked by the first magnetic shielding member 122.

[0058] Please refer to Figure 6 , when the foldable electronic device 100 is in the folded state, the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 is the first area, and at least a part of the first magnetic member 13 is exposed outside the first magnetic shielding member 122 to magnetically attract the second body 20. In other words, since at least a part of the first magnetic member 13 is exposed outside the first magnetic shielding member 122, the exposed first magnetic member 13 can magnetically attract the second body 20, so that the foldable electronic device 100 can be stably maintained in the folded state.

[0059] It should be noted that the first area can be zero, that is, the first magnetic member 13 is not blocked by the first magnetic shielding member 122, or in other words, the orthographic projection of the first magnetic shielding member 122 on the first housing 11 does not overlap with the orthographic projection of the first magnetic member 13 on the first housing 11. At this time, the maximum mutual magnetic attraction effect can be generated between the first magnetic member 13 and the second body 20.

[0060] Please refer to Figure 5When the foldable electronic device 100 is in the unfolded state, the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 is the second area, and the second area is greater than the first area, so as to magnetically isolate at least part of the first magnetic member 13 from the outside through the first magnetic shielding member 122. In other words, the first magnetic shielding member 122 faces at least part of the first magnetic member 13, causing at least part of the first magnetic member 13 to be magnetically isolated. Or, the orthographic projection of the first magnetic shielding member 122 on the first housing 11 overlaps with the orthographic projection of the first magnetic member 13 on the first housing 11. At this time, the first magnetic shielding member 122 blocks at least part of the first magnetic member 13. Therefore, this blocked part of the first magnetic member 13 is magnetically isolated by the first magnetic shielding member 122. Since the second area is greater than the first area, the magnetic attraction ability of the first magnetic member 13 to foreign objects outside is weakened, or there is no magnetic attraction ability at all. Foreign objects outside located on the side of the first magnetic shielding member 122 away from the first magnetic member 13 will not be magnetically attracted by the first magnetic member 13 and adhere to the first non-bending display area 41 of the first body 10.

[0061] It should be noted that the second area can be the maximum blocked area of the first magnetic member 13, that is, the orthographic projection of the first magnetic member 13 on the first magnetic shielding member 122 completely falls within the range where the first magnetic shielding member 122 is located. At this time, the first magnetic member 13 is completely blocked by the first magnetic shielding member 122, and the first magnetic member 13 has no magnetic attraction ability to foreign objects outside.

[0062] Furthermore, during the folding process of the foldable electronic device 100, the first driving member 123 is used to drive the first magnetic shielding member 122 or the first magnetic member 13 as the included angle α between the first body 10 and the second body 20 decreases, so that the first magnetic shielding member 122 and the first magnetic member 13 gradually move away from each other, and further the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 gradually decreases.

[0063] In an embodiment, during the folding process of the foldable electronic device 100, the first driving member 123 is used to drive the first magnetic member 13 as the included angle α between the first body 10 and the second body 20 decreases, so that the first magnetic shielding member 122 and the first magnetic member 13 gradually move away from each other, and further the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 gradually decreases, that is, the facing area between the first magnetic member 13 and the first magnetic shielding member 122 gradually decreases. Among them, the facing area is the area of the first magnetic member 13 blocked by the first magnetic shielding member 122.

[0064] In another embodiment, during the folding process of the foldable electronic device 100, the first driving member 123 is configured to drive the first magnetic shielding member 122 as the included angle α between the first body 10 and the second body 20 decreases, so that the first magnetic shielding member 122 and the first magnetic member 13 gradually move away from each other, and thus the area of the first magnetic member 13 shielded by the first magnetic shielding member 122 gradually decreases, that is, the facing area between the first magnetic member 13 and the first magnetic shielding member 122 gradually decreases.

[0065] In yet another embodiment, during the folding process of the foldable electronic device 100, the first driving member 123 is configured to drive the first magnetic shielding member 122 and the first magnetic member 13 as the included angle α between the first body 10 and the second body 20 decreases, so that the first magnetic shielding member 122 and the first magnetic member 13 gradually move away from each other, and thus the area of the first magnetic member 13 shielded by the first magnetic shielding member 122 gradually decreases, that is, the facing area between the first magnetic member 13 and the first magnetic shielding member 122 gradually decreases.

[0066] In some embodiments, before the foldable electronic device 100 needs to be changed from the unfolded state to the folded state, the first magnetic shielding member 122 is first driven to a position away from the first magnetic member 13, so that the first magnetic member 13 is not magnetically isolated by the first magnetic shielding member 122. Then, the foldable electronic device 100 is changed from the unfolded state to the folded state, so that the first magnetic member 13 can adsorb the second body 20 with the maximum magnetic attraction force, facilitating the quick folding of the first body 10 and the second body 20. However, before folding, since the first magnetic member 13 already has the maximum ability to magnetically adsorb foreign objects from the outside, during the folding process, foreign objects from the outside may still be magnetically adsorbed by the first magnetic member 13 and attached to the first non-bending display area 41 of the first body 10, and then the first non-bending display area 41 and the second non-bending display area 42 are damaged by the foreign objects from the outside (the problem of damage).

[0067] During the folding process of the folding device provided in the present application, the first magnetic shielding member 122 and the first magnetic member 13 will gradually move away from each other as the included angle α decreases, so that the magnetic adsorption ability of the first magnetic member 13 to the outside gradually increases as the included angle α decreases. It can be understood that when the included angle α is large, the magnetic adsorption ability of the first magnetic member 13 to the outside is weak, and foreign objects from the outside are not easily magnetically adsorbed and attached to the first non-bending display area 41 of the first body 10; when the included angle α is small, although the magnetic adsorption ability of the first magnetic member 13 to the outside is strong, it is already difficult for foreign objects from the outside to enter the small gap between the first body 10 and the second body 20. Therefore, the folding device provided in the present application can better avoid the problem of damage during the folding process.

[0068] Further, during the unfolding process of the foldable electronic device 100, the first driving member 123 is configured to drive the first magnetic shielding member 122 and / or the first magnetic member 13 as the included angle α between the first body 10 and the second body 20 increases, so that the first magnetic shielding member 122 and the first magnetic member 13 gradually approach each other, and thus the area of the first magnetic member 13 shielded by the first magnetic shielding member 122 gradually increases, that is, the facing area between the first magnetic member 13 and the first magnetic shielding member 122 gradually increases.

[0069] That is to say, during the unfolding process of the folding device provided in the present application, since the first magnetic shielding member 122 and the first magnetic member 13 gradually approach each other as the included angle α increases, the magnetic adsorption ability of the first magnetic member 13 to the outside gradually weakens as the included angle α increases. It can be understood that when the included angle α is small, although the magnetic adsorption ability of the first magnetic member 13 to the outside is strong, it is difficult for foreign objects to enter the small gap between the first body 10 and the second body 20; when the included angle α is large, the magnetic adsorption ability of the first magnetic member 13 to the outside is weak, and foreign objects are not easily magnetically attracted and attached to the first non-bending display area 41 of the first body 10. In addition, during the unfolding process, since the first magnetic member 13 magnetically adsorbs the second body 20, the unfolding operation of the user needs to overcome the resistance of the magnetic attraction, so that the feel of the user's two-handed unfolding operation is better.

[0070] It should be noted that in the first body 10, the number of the first magnetic shielding assemblies 12 can be one or multiple (such as two). For example, as Figure 5 shown, the number of the first magnetic shielding assemblies 12 is two, and the two first magnetic shielding assemblies 12 are both arranged at one end of the first housing 11 away from the second body 20, one of the first magnetic shielding assemblies 12 is arranged at one corner of the first housing 11, and the other first magnetic shielding assembly 12 is arranged at the other corner of the first housing 11. Of course, in other embodiments, the number of the first magnetic shielding assemblies 12 can also be three, four, etc.

[0071] Please refer to Figure 5 and Figure 7 , the second body 20 includes a second housing 21, a second magnetic member 23 (see Figure 7 ), and a second magnetic shielding assembly 22. The second magnetic shielding assembly 22 includes a second magnetic shielding member 222 and a second driving member 223. At least one of the second magnetic shielding member 222 and the second magnetic member 23 is movably connected to the second housing 21. The second driving member 223 is configured to drive the second magnetic shielding member 222 to move and / or drive the second magnetic member 23 to move, so as to change the area of the second magnetic member 23 shielded by the second magnetic shielding member 222.

[0072] Please refer to Figure 7, when the foldable electronic device 100 is in a folded state, the area of the first magnetic member blocked by the first magnetic shielding member is the third area, and the second magnetic member 23 is at least partially exposed outside the second magnetic shielding member 222 to magnetically attract the first magnetic member 13. Please refer to Figure 5 , when the foldable electronic device 100 is in an unfolded state, the area of the second magnetic member 23 blocked by the second magnetic shielding member 222 is the fourth area, and the fourth area is greater than the third area, so as to magnetically isolate at least part of the second magnetic member 23 from the outside through the second magnetic shielding member 222.

[0073] During the folding process of the foldable electronic device 100, the second driving member 223 is used to drive the second magnetic shielding member 222 and / or the second magnetic member 23 as the included angle α between the first body 10 and the second body 20 decreases, so that the second magnetic shielding member 222 and the second magnetic member 23 gradually move away from each other, and thus the area of the second magnetic member 23 blocked by the second magnetic shielding member 222 gradually decreases.

[0074] During the unfolding process of the foldable electronic device 100, the second driving member 223 is used to drive the second magnetic shielding member 222 and / or the second magnetic member 23 as the included angle α between the first body 10 and the second body 20 increases, so that the second magnetic shielding member 222 and the second magnetic member 23 gradually approach each other, and thus the area of the second magnetic member 23 blocked by the second magnetic shielding member 222 gradually increases.

[0075] It should be noted that the second body 20 and the first body 10 may adopt the same or substantially the same structure. For the situation of the second body 20, please refer to the relevant drawings and descriptions of the first body 10. In the following content, the second body 20 will not be further introduced, and only the first body 10 will be used as an object for explanation.

[0076] Please refer to Figure 8 , optionally, the first magnetic shielding assembly 12 further includes a rotating shaft 125, and the first magnetic shielding member 122 is rotatably connected to the first housing 11 through the rotating shaft 125. That is to say, the opposite ends of the rotating shaft 125 are respectively connected to the first magnetic shielding member 122 and the first housing 11, so that the first magnetic shielding member 122 can rotate relative to the first housing 11. During the folding process of the foldable electronic device 100, the first magnetic shielding member 122 rotates in the first preset direction X1; during the unfolding process of the foldable electronic device 100, the first magnetic shielding member 122 rotates in the second preset direction X2. Among them, the first preset direction X1 and the second preset direction X2 are opposite.

[0077] In one embodiment, one end of the rotating shaft 125 is fixedly connected to the first magnetic shielding member 122, and the other end of the rotating shaft 125 is rotatably connected to the first housing 11. During the folding or unfolding process of the foldable electronic device 100, the rotating shaft 125 and the first magnetic shielding member 122 rotate synchronously relative to the first housing 11 in the first preset direction X1 or the second preset direction X2. In another embodiment, one end of the rotating shaft 125 is fixedly connected to the first housing 11, and the other end of the rotating shaft 125 is connected to the first magnetic shielding member 122. During the folding or unfolding process of the foldable electronic device 100, the first magnetic shielding member 122 rotates relative to the first housing 11 and the rotating shaft 125 in the first preset direction X1 or the second preset direction X2.

[0078] Please refer to Figure 9 , optionally, the first magnetic shielding member 122 is slidably connected to the first housing 11. During the folding process of the foldable electronic device 100, the first magnetic shielding member 122 translates in the third preset direction X3; during the unfolding process of the foldable electronic device 100, the first magnetic shielding member 122 translates in the fourth preset direction X4. Wherein, the third preset direction X3 and the fourth preset direction X4 are opposite.

[0079] Please refer to Figure 10 and Figure 11 , the first housing 11 may be provided with a first stop structure 111 and a second stop structure 112. The first stop structure 111 and the second stop structure 112 may be oppositely arranged, and the first magnetic shielding member 122 is arranged between the first stop structure 111 and the second stop structure 112 to limit the degree of freedom of the first magnetic shielding member 122 in the relative direction of the first stop structure 111 and the second stop structure 112. Further, the orthographic projection of the first stop structure 111 and the second stop structure 112 in the thickness direction of the first body 10 falls within the range of the first magnetic shielding member 122, or rather, the distance between the first stop structure 111 and the second stop structure 112 is a first dimension H1, and the dimension of the first magnetic shielding member 122 in the relative direction of the first stop structure 111 and the second stop structure 112 is a second dimension H2, and the first dimension H1 is less than the second dimension H2. With such a setting, the first stop structure 111 and the second stop structure 112 can limit the degree of freedom of the first magnetic shielding member 122 in the thickness direction of the first body 10 and prevent the first magnetic shielding member 122 from detaching.

[0080] Please refer to Figure 12 and Figure 13, Optionally, the foldable electronic device 100 further includes a controller 50 and a detector 60. The controller 50 is electrically connected to the detector 60 and the first driving member 123. The detector 60 is used to detect the included angle α formed by the first body 10 and the second body 20. The first driving member 123 is an electronic device that can output power, such as a motor. The first driving member 123 can be directly connected to the first magnetic shielding member 122, or can be indirectly connected to the first magnetic shielding member 122 through transmission members such as racks, gears, and screws. The controller 50 controls the first driving member 123 to drive the first magnetic shielding member 122 to a position corresponding to the included angle α according to the included angle α.

[0081] Specifically, there is a one-to-one mapping relationship between the included angle α formed by the first body 10 and the second body 20 and the relative position of the first magnetic shielding member 122 and the first magnetic member 13. For example, when the included angle α is 30°, the facing area of the first magnetic shielding member 122 and the first magnetic member 13 is S1; when the included angle α is 45°, the facing area of the first magnetic shielding member 122 and the first magnetic member 13 is S2; when the included angle α is 60°, the facing area of the first magnetic shielding member 122 and the first magnetic member 13 is S3, where S1 < S2 < S3. According to this mapping relationship, the controller 50 can determine the facing area of the first magnetic shielding member 122 and the first magnetic member 13 according to the included angle α, and then control the first driving member 123 to output power to drive the first magnetic shielding member 122 so that the facing area of the first magnetic shielding member 122 and the first magnetic member 13 corresponds to the current included angle α. In this embodiment, the first driving member 123 uses an electronic device, which can simplify the driving structure to reduce space occupation. For example, as Figure 13 shown, the first driving member 123 uses a motor, a gear is sleeved on the outer periphery of the output shaft of the motor, and a rack is connected to the first magnetic shielding member 122, and the rack is cooperatively connected to the gear on the output shaft of the motor. When the output shaft rotates, the first magnetic shielding member 122 can move along the third preset direction X3 or the fourth preset direction X4.

[0082] Please combine Figure 5 with reference to Figure 14 and Figure 15 , Optionally, the foldable electronic device 100 further includes a hinge assembly 30. The hinge assembly 30 includes a hinge body 33 and a first movable assembly 31 and a second movable assembly 32 that are respectively rotatably connected to both ends of the hinge body 33. The first movable assembly 31 is connected to the first housing 11 and the first driving member 123. The second movable assembly 32 is connected to the second body 20. During the folding or unfolding process of the foldable electronic device 100, the first movable assembly 31 extends or contracts so that the first driving member 123 drives the first magnetic shielding member 122 away from or close to the first magnetic member 13.

[0083] Specifically, both the first movable component 31 and the second movable component 32 can rotate relative to the hinge body 33, such that the first movable component 31 and the second movable component 32 can move towards each other to fold or move away from each other to unfold. Among them, the first movable component 31 is connected to the first body 10, and the second movable component 32 is connected to the second body 20, such that the first body 10 and the second body 20 can achieve moving towards each other to fold or moving away from each other to unfold through the hinge assembly 30.

[0084] During the folding process of the hinge assembly 30, the first movable component 31 and the second movable component 32 elongate; during the unfolding process of the hinge assembly 30, the first movable component 31 and the second movable component 32 shorten. By utilizing the characteristic that "the hinge assembly 30 can elongate or shorten", the first magnetic shielding member 122 and the hinge assembly 30 are associated through the first driving member 123, then the driving of the first magnetic shielding member 122 can be achieved, such that the first magnetic shielding member 122 moves away from the first magnetic member 13 or approaches the first magnetic member 13, which will be specifically described later.

[0085] In this embodiment, using the hinge assembly 30 to drive the first magnetic shielding member 122 not only reduces the driving structure and saves space, but also associates the movement of the first magnetic shielding member 122 with the hinge assembly 30. Under a pure mechanical structure, the facing area between the first magnetic shielding member 122 and the first magnetic member 13 can be made to change following the change of the included angle α of the foldable electronic device 100, without the need for electric energy drive, such that the foldable electronic device 100 can avoid the above-mentioned pinching problem in any scenario (such as a scenario where the battery runs out).

[0086] When the foldable electronic device 100 is a folding screen mobile phone and adopts the elongatable or contractible hinge assembly 30 in this embodiment, the problem of the flexible screen 40 being stretched or squeezed can be avoided or reduced. Specifically, during the folding and unfolding processes of the folding screen mobile phone, since the hinge assembly 30 is located outside the flexible screen 40 (inward folding type), the bending radius of the hinge assembly 30 is greater than the bending radius of the flexible screen 40. To avoid stretching or compressing the flexible screen 40, the hinge assembly 30 needs to be able to change its length during the folding and unfolding processes of the folding screen mobile phone. If the folding screen mobile phone adopts an elongatable or contractible hinge assembly 30, during the folding process of the folding screen mobile phone, the length of the hinge assembly 30 can be stretched, thereby being able to avoid generating a compressive force on the flexible screen 40; during the unfolding process of the folding screen mobile phone, the length of the hinge assembly 30 can be shortened, thereby being able to avoid generating a tensile force on the flexible screen 40.

[0087] The following specifically introduces the structural composition of the hinge assembly 30 and the movement relationship between its components with reference to the accompanying drawings. It should be noted that the second movable component 32 may adopt the same structure as the first movable component 31. In the following description of this application, only the first movable component 31 will be elaborated. For the situation of the second movable component 32, please refer to the drawings and descriptions of the first movable component 31.

[0088] Please refer to Figure 16 , the first movable component 31 includes a base 313, a first rotating arm 311, and a second rotating arm 312. Among them, the base 313 is fixedly connected to the first housing 11. That is to say, during the unfolding or folding process of the foldable electronic device 100, the base 313 moves synchronously with the first housing 11. The connection manner between the base 313 and the first housing 11 can be but is not limited to bonding, welding, or connecting with threaded parts such as screws.

[0089] Among them, one end of the first rotating arm 311 is slidably connected to the base 313. The sliding connection manner between the two can be but is not limited to the form of a chute and a slider. For example, as Figure 17 shown, a guiding groove 3131 is provided on the base 313, and the first rotating arm 311 acts as a slider and is slidably arranged in the guiding groove 3131. Another example is that a guiding groove 3131 is provided on the first rotating arm 311, and the base 313 acts as a slider and is slidably arranged in the guiding groove 3131.

[0090] Among them, the other end of the first rotating arm 311 is rotatably connected to the hinge body 33. The rotational connection manner between the two can be but is not limited to the form of a shaft and a hole. For example, as Figure 17 shown, a first mating hole 3111 is provided on the first rotating arm 311, and a first shaft section 331 is provided on the hinge body 33. The first shaft section 331 is rotatably inserted into the first mating hole 3111. Another example is that a first mating hole 3111 is provided on the hinge body 33, and a first shaft section 331 is provided on the first rotating arm 311. The first shaft section 331 is rotatably inserted into the first mating hole 3111.

[0091] Among them, one end of the second rotating arm 312 is rotatably connected to the base 313. The rotational connection manner between the two can be but is not limited to the form of a shaft and a hole. For example, as Figure 18 shown, a second mating hole 3121 is provided on the second rotating arm 312, and a second shaft section 3132 is provided on the base 313. The second shaft section 3132 is rotatably inserted into the second mating hole 3121. Another example is that a second mating hole 3121 is provided on the base 313, and a second shaft section 3132 is provided on the second rotating arm 312. The second shaft section 3132 is rotatably inserted into the second mating hole 3121.

[0092] Wherein, the other end of the second rotating arm 312 is rotatably connected to the hinge body 33. The rotation connection mode between the two can be, but is not limited to, the shaft and groove matching form. For example, as Figure 19 shown, an arc shaft 3122 is provided on the second rotating arm 312, an arc groove 332 is provided on the hinge body 33, and the arc shaft 3122 is rotatably arranged in the arc groove 332. Another example is that an arc shaft 3122 is provided on the hinge body 33, an arc groove 332 is provided on the second rotating arm 312, and the arc shaft 3122 is rotatably arranged in the arc groove 332.

[0093] Furthermore, the central axis corresponding to the rotation of the first rotating arm 311 around the hinge body 33 is defined as the first central axis rotation. The central axis corresponding to the rotation of the second rotating arm 312 around the hinge body 33 is defined as the second central axis rotation. The first central axis and the second central axis are parallel and do not coincide, so that the first movable assembly 31 can be elongated or shortened when rotating around the hinge body 33.

[0094] Taking the user using both hands to fold or unfold the foldable electronic device 100 as an example, when the user uses both hands to drive the first body 10 and the second body 20 to fold while approaching each other or unfold while moving away from each other, the first housing 11 applies a force to the base 313, and this force drives the base 313 to rotate. The base 313 then drives the first rotating arm 311 to rotate around the first central axis. At the same time, the base 313 also drives the second rotating arm 312 to rotate around the second central axis. Since the first central axis and the second central axis do not coincide, during the rotation process, the base 313 will slide relative to the first rotating arm 311, thus forming a situation where the base 313 moves away from or approaches the hinge body 33.

[0095] Please refer to Figure 20 , when the foldable electronic device 100 is folded, the base 313 moves away from the hinge body 33, and the first movable assembly 31 is shown as being elongated. Please refer to Figure 17 , when the foldable electronic device 100 is unfolded, the base 313 approaches the hinge body 33, and the first movable assembly 31 is shown as being shortened. Please refer to Figure 21 , one end of the first driving member 123 away from the first magnetic separation member 122 is fixedly connected to the first rotating arm 311, and the connection mode can be, but is not limited to, bonding, welding, clamping, etc. When the foldable electronic device 100 is folded or unfolded, the base 313 and the first rotating arm 311 slide relative to each other, so that the first rotating arm 311 drives the first magnetic separation member 122 to move through the first driving member 123.

[0096] It can be understood that during the folding or unfolding process of the foldable electronic device 100, due to the relative sliding between the base 313 and the first rotating arm 311, and since the base 313 is fixedly connected to the first housing 11, there is relative movement between the first rotating arm 311 and the first housing 11. In addition, since the first driving member 123 is fixedly connected to the first rotating arm 311, the first rotating arm 311 will drive the first driving member 123 to move relative to the first housing 11, so that the first driving member 123 can drive the first magnetic shielding member 122 provided on the first housing 11 to move.

[0097] Please refer to Figure 21 , optionally, the first driving member 123 includes a strip-shaped wire 1231. The wire 1231 can be but is not limited to non-flexible wires such as steel wires, iron wires, Bowden wires, etc. The flexible wires mentioned here refer to wires that do not have the ability to resist bending, such as nylon wires. One end of the wire 1231 is connected to the first rotating arm 311, and the other end is connected to the first magnetic shielding member 122.

[0098] During the folding process of the foldable electronic device 100, the wire 1231 drives the first magnetic shielding member 122 to move under the pulling of the first rotating arm 311, so that the first magnetic shielding member 122 and the first magnetic member 13 move away from each other. Specifically, during the folding process of the foldable electronic device 100, through the sliding fit between the base 313 and the first rotating arm 311, the first housing 11 moves in the first direction Y1 away from the hinge body 33 synchronously with the base 313 (i.e., the process of the first movable component 31 extending). Relatively speaking, the first rotating arm 311 pulls the wire 1231 in the second direction Y2 opposite to the first direction Y1 (see Figure 21 ), and the wire 1231 then pulls the first magnetic shielding member 122 provided on the first housing 11 in its own extending direction, so that the first magnetic shielding member 122 gradually moves away from the first magnetic member 13.

[0099] During the unfolding process of the foldable electronic device 100, the wire 1231 drives the first magnetic shielding member 122 to move under the pushing of the first rotating arm 311, so that the first magnetic shielding member 122 and the first magnetic member 13 move closer to each other. Specifically, during the unfolding process of the foldable electronic device 100, through the sliding fit between the base 313 and the first rotating arm 311, the first housing 11 moves in the second direction Y2 close to the hinge body 33 synchronously with the base 313 (i.e., the process of the first movable component 31 shortening). Relatively speaking, the first rotating arm 311 pushes the wire 1231 in the first direction Y1 opposite to the second direction Y2 (see Figure 21 ), and the wire 1231 then pushes the first magnetic shielding member 122 provided on the first housing 11 in its own extending direction, so that the first magnetic shielding member 122 gradually moves closer to the first magnetic member 13.

[0100] In this embodiment, by using a simple wire 1231 to associate the first magnetic shielding member 122 and the first rotating arm 311, the structure is simple, the cost is low, it does not occupy too much space, and the reliability is high.

[0101] Please refer to Figure 22 and Figure 23 , optionally, the first magnetic shielding assembly 12 further includes an elastic element 124, and the first driving member 123 includes a strip-shaped wire 1231. One end of the wire 1231 is connected to the first rotating arm 311, and the other end is connected to the first magnetic shielding member 122. The elastic element 124 is connected to the first magnetic shielding member 122. Among them, the wire 1231 can be a non-flexible wire such as a steel wire or an iron wire, or a flexible wire such as nylon. The elastic element 124 refers to an element that can store and release elastic potential energy. The elastic element 124 can be, but is not limited to, a torsion spring or a tension spring.

[0102] During the folding process of the foldable electronic device 100, the wire 1231 drives the first magnetic shielding member 122 to move under the pulling of the first rotating arm 311, so that the first magnetic shielding member 122 and the first magnetic member 13 move away from each other, and the elastic element 124 deforms under the drive of the first magnetic shielding member 122, increasing the elastic potential energy. During the unfolding process of the foldable electronic device 100, the elastic element 124 deforms autonomously to release the elastic potential energy and drives the first magnetic shielding member 122 to move, so that the first magnetic shielding member 122 and the first magnetic member 13 approach each other.

[0103] The difference between this embodiment and the previous embodiment is that an elastic element 124 is added. The elastic element 124 applies a pre-tightening force to the first magnetic shielding member 122 to always tension the first magnetic shielding member 122. At this time, the elastic potential energy of the elastic element 124 is defined as the first potential energy. During the folding process of the foldable electronic device 100, the first rotating arm 311 pulls the first magnetic shielding member 122 away from the first magnetic member 13 through the wire 1231, and the first magnetic shielding member 122 drives the elastic element 124 to generate elastic deformation. At this time, the elastic potential energy of the elastic element 124 increases from the first potential energy to the second potential energy; during the unfolding process of the foldable electronic device 100, since the first rotating arm 311 relaxes the wire 1231, the elastic element 124 can deform autonomously and drive the first magnetic shielding member 122 to move closer to the first magnetic member 13 until the second potential energy decreases to the first potential energy.

[0104] In this embodiment, since the elastic element 124 can drive the first magnetic shielding member 122 autonomously during the unfolding process of the foldable electronic device 100, the problem that the wire 1231 is bent and cannot push the first magnetic shielding member 122 is avoided. Therefore, the setting of the elastic element 124 is beneficial to ensuring that the first magnetic shielding member 122 can effectively magnetically isolate the first magnetic member 13.

[0105] Exemplarily introduced below in conjunction with the accompanying drawings are two elastic elements 124, namely extension springs and torsion springs. Of course, in other embodiments, other elastic elements 124 or arrangement methods may also be adopted to achieve related functions, which will not be exemplified one by one here.

[0106] Please refer to Figure 22 , where the elastic element 124 is an extension spring or a compression spring. Among them, an extension spring is also called a tension spring or a tensile spring, which will elongate when subjected to an axial tensile force and will automatically shorten when the tensile force is removed. A compression spring is also called a compression spring, which will shorten when subjected to an axial compressive force and will automatically elongate when the compressive force is removed. The two ends of the extension spring or the compression spring are respectively connected to the first magnetic shielding member 122 and the first housing 11. During the folding process of the foldable electronic device 100, the extension spring or the compression spring is stretched or compressed by the first magnetic shielding member 122. During the unfolding process of the foldable electronic device 100, the extension spring automatically shortens or elongates to drive the movement of the first magnetic shielding member 122. In this embodiment, the first magnetic shielding member 122 can be slidably connected to the first housing 11 or rotatably connected to the first housing 11.

[0107] In one embodiment, the elastic element 124 is an extension spring, and the extension spring can be arranged on the side of the first magnetic shielding member 122 away from the wire 1231, as Figure 22 shown. The extension spring applies a pre-tightening tensile force to the first magnetic shielding member 122, and the direction of the pre-tightening tensile force is opposite to the direction of the tensile force applied by the wire 1231 to the first magnetic shielding member 122. During the folding process of the foldable electronic device 100, the wire 1231 pulls the first magnetic shielding member 122, and the first magnetic shielding member 122 then stretches the extension spring. During this process, the elastic potential energy of the extension spring increases; during the unfolding process of the foldable electronic device 100, the extension spring automatically shortens, thereby pulling the first magnetic shielding member 122 to move. During this process, the elastic potential energy of the extension spring decreases.

[0108] In another embodiment, the elastic element 124 is a compression spring, and the compression spring can be arranged on the side of the first magnetic shielding member 122 close to the wire 1231. The compression spring applies a pre-tightening thrust to the first magnetic shielding member 122, and the direction of the pre-tightening thrust is opposite to the direction of the tensile force applied by the wire 1231 to the first magnetic shielding member 122. During the folding process of the foldable electronic device 100, the wire 1231 pulls the first magnetic shielding member 122, and the first magnetic shielding member 122 then compresses the compression spring. During this process, the elastic potential energy of the compression spring increases; during the unfolding process of the foldable electronic device 100, the compression spring automatically elongates, thereby pushing the first magnetic shielding member 122 to move. During this process, the elastic potential energy of the compression spring decreases.

[0109] Please refer to Figure 23, the elastic element 124 is a torsion spring, also known as a twisting spring, which will twist when subjected to an external force in the circumferential direction and will automatically reverse twist when the external force is removed. The two ends of the torsion spring are respectively connected to the first magnetic shielding member 122 and the first housing 11. The tension spring applies a pre-tightening torque to the first magnetic shielding member 122, and the direction of the pre-tightening torque is opposite to the direction of the torque applied by the wire 1231 to the first magnetic shielding member 122. In this embodiment, the first magnetic shielding member 122 can be rotatably connected to the first housing 11 through a rotating shaft 125. The torsion spring can be sleeved on the outer periphery of the rotating shaft 125, that is, the rotating shaft 125 passes through the torsion spring.

[0110] During the folding process of the foldable electronic device 100, the wire 1231 pulls the first magnetic shielding member 122 to rotate, and the torsion spring is then driven by the first magnetic shielding member 122 to twist. During this process, the elastic potential energy of the torsion spring increases. During the unfolding process of the foldable electronic device 100, the torsion spring automatically reversely twists to drive the first magnetic shielding member 122 to perform a rotational motion. During this process, the elastic potential energy of the torsion spring decreases.

[0111] Please refer to Figure 24 and Figure 25 , optionally, the first driving member 123 further includes a long strip-shaped sleeve 1232, and its material can be but not limited to metals, plastics, etc. The sleeve 1232 is connected to the first housing 11, and the connection manner between the sleeve 1232 and the first housing 11 can be but not limited to welding, bonding, snap connection, etc. The inside of the sleeve 1232 is hollow, and the sleeve 1232 is sleeved on the outer periphery of the wire 1231, or rather, the wire 1231 passes through the sleeve 1232. With such a setting, the wire 1231 can be fixed to prevent the wire 1231 from shaking and winding around other components. In addition, in the embodiment where the wire 1231 adopts a non-flexible wire (such as a steel wire or an iron wire) in the front, during the unfolding process of the foldable electronic device 100, the first rotating arm 311 uses the wire 1231 to push the first magnetic shielding member 122 to move. It can be understood that since the wire 1231 is long strip-shaped, it can withstand a large tensile force in its extending direction. However, when it is subjected to a thrust (or pressure) in its extending direction, it is prone to bending deformation. Therefore, the sleeve 1232 in this embodiment can adopt a hard tube that is not easily bent and deformed to prevent the wire 1231 from bending excessively when subjected to a thrust, so as to ensure that the wire 1231 can effectively push the first magnetic shielding member 122.

[0112] Please refer to Figure 24 and Figure 26, Optionally, the first driving member 123 further includes a stop member 1233, and the stop member 1233 is connected to the sleeve 1232. A stop groove 114 is provided on the first housing 11, and the stop member 1233 is disposed in the stop groove 114. At least one of the length, thickness, and height of the stop member 1233 is greater than the outer diameter of the sleeve 1232 to define the free end of the stop member 1233. Through the cooperation of the stop member 1233 and the stop groove 114, the degree of freedom of the sleeve 1232 can be defined in the extending direction of the sleeve 1232, thereby preventing the sleeve 1232 from being pulled by the wire 1231. The material of the stop member 1233 can be, but is not limited to, metal, plastic, etc. The specific number of the stop members 1233 can be, but is not limited to, 1, 2, 3, 4, 5, etc. When the number of the stop members 1233 is multiple, the multiple stop members 1233 can be arranged at intervals in the extending direction of the sleeve 1232. In Figure 26 In this case, the number of the stop members 1233 is 2, and the two stop members 1233 are respectively connected to opposite ends of the sleeve 1232.

[0113] Please refer to Figure 27 , the first housing 11 is provided with a receiving groove 113, and the wire 1231 is disposed in the receiving groove 113. The receiving groove 113 can also be combined with the previous embodiment. For example, the sleeve 1232 through which the wire 1231 passes is disposed in the receiving groove 113, and the receiving groove 113 communicates with the stop groove 114, and the stop groove 114 cooperates with the stop member 1233 to limit the sleeve 1232 in the receiving groove 113.

[0114] In this embodiment, disposing the wire 1231 in the receiving groove 113 is equivalent to burying the wire 1231 in the first housing 11, preventing the wire 1231 from shaking and interfering with other components, and also reserving more space for the arrangement of other components. In addition, by limiting the wire 1231 in the receiving groove 113, its shape can be defined by the receiving groove 113, preventing the wire 1231 from being greatly bent when receiving a thrust, thereby ensuring that the wire 1231 can effectively push the first magnetic separation member 122.

[0115] In summary, in the foldable electronic device 100 provided by the present application, a first magnetic member 13, a first magnetic shielding member 122, and a first driving member 123 are provided on the first body 10. Among them, the first driving member 123 can drive the first magnetic shielding member 122 and / or the first magnetic member 13 to move, so as to change the position of the first magnetic shielding member 122 relative to the first magnetic member 13. When the foldable electronic device 100 is in the folded state, the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 is the first area, and at least a part of the first magnetic member 13 is exposed outside the first magnetic shielding member 122. The exposed part of the first magnetic member 13 magnetically adsorbs the second magnetic member 23 of the second body 20, so that the foldable electronic device 100 can be stably maintained in the folded state; when the foldable electronic device 100 is in the unfolded state, the area of the first magnetic member 13 blocked by the first magnetic shielding member 122 is the second area, and the second area is larger than the first area. At this time, the magnetic attraction ability of the first magnetic member 13 to foreign objects outside is weakened or there is no magnetic attraction ability, so foreign objects outside will not be magnetically adsorbed to the first body 10 by the first magnetic member 13.

[0116] Moreover, during the folding process of the folding device, the first magnetic shielding member 122 and the first magnetic member 13 will gradually move away as the included angle α decreases, so that the magnetic attraction ability of the first magnetic member 13 to the outside gradually increases as the included angle α decreases. It can be understood that when the included angle α is large, the magnetic attraction ability of the first magnetic member 13 to the outside is weak, and foreign objects outside are not easily magnetically attracted and attached to the first body 10; when the included angle α is small, although the magnetic attraction ability of the first magnetic member 13 to the outside is strong, it is already difficult for foreign objects outside to enter the small gap between the first body 10 and the second body 20. Therefore, the folding device provided by the present application can better avoid the problem of being crushed during the folding process.

[0117] In addition, during the unfolding process of the folding device, since the first magnetic shielding member 122 and the first magnetic member 13 will gradually approach as the included angle α increases, the magnetic attraction ability of the first magnetic member 13 to the outside gradually decreases as the included angle α increases. It can be understood that when the included angle α is small, although the magnetic attraction ability of the first magnetic member 13 to the outside is strong, it is difficult for foreign objects outside to enter the small gap between the first body 10 and the second body 20; when the included angle α is large, the magnetic attraction ability of the first magnetic member 13 to the outside is weak, and foreign objects outside are not easily magnetically attracted and attached to the first body 10. In addition, during the unfolding process, since the first magnetic member 13 will magnetically adsorb the second body 20, the unfolding operation of the user needs to overcome the resistance of the magnetic attraction, so that the feel of the user's two-handed unfolding operation is better.

[0118] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application, and these improvements and refinements are also considered to be within the protection scope of the present application.
