The first body portion and the second body portion are rotatably connected. Each pair of magnetic components includes a first magnetic component and a second magnetic component, which are respectively disposed on the first body portion and the second body portion. At least one of the first magnetic component and the second magnetic component in each pair is a permanent magnet. Each magnetic shielding component is disposed on a target body portion corresponding to at least one permanent magnet. The target body portion is the body portion on which the permanent magnet is disposed. When the foldable terminal device switches between a folded state and an unfolded state, the position of the magnetic shielding component switches between a first position and a second position on the corresponding target body portion to shield different proportions of the magnetic attraction force generated by the corresponding permanent magnet.

Description

Technical Field

[0001] This application relates to the field of foldable devices, and more particularly to a foldable terminal device. Background Technology

[0002] To ensure a tight folding effect, foldable terminal devices require one or more pairs of magnets placed inside the frame to provide magnetic attraction when folded, helping to achieve stable folding. However, when the terminal is unfolded, these magnets easily attract small magnetic particles, which can easily compress and damage the surface of the foldable terminal. Summary of the Invention

[0003] This application provides a foldable terminal device that can weaken or eliminate the magnetic attraction of the permanent magnet when the foldable terminal device is in the unfolded state, so as to solve the above-mentioned technical problems.

[0004] This application provides a foldable terminal device, comprising:

[0005] Rotating structure;

[0006] The first body part and the second body part are rotatably connected by a rotating structure;

[0007] At least one pair of magnetic components, each pair of magnetic components includes a first magnetic component and a second magnetic component, and the first magnetic component and the second magnetic component of each pair of magnetic components are respectively disposed on a first body part and a second body part. When the first body part and the second body part are in a folded state, the first magnetic component and the second magnetic component of each pair of magnetic components are magnetically connected. When the first body part and the second body part are in an unfolded state, the first magnetic component and the second magnetic component of each pair of magnetic components are separated from each other. At least one of the first magnetic component and the second magnetic component of each pair of magnetic components is a permanent magnet.

[0008] At least one magnetic shielding element is provided, each magnetic shielding element being disposed on the target body part at a position corresponding to at least one permanent magnet. The target body part is a body part provided with permanent magnets. When the foldable terminal device switches between a folded state and an unfolded state, the position of the magnetic shielding element switches between a first position and a second position on the corresponding target body part to shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than a first proportion or to shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than a second proportion, wherein the first proportion is less than the second proportion.

[0009] Therefore, during the unfolding or folding of the foldable terminal device, this application can link the magnetic shielding component to switch positions, thereby changing the shielding ratio of the magnetic attraction force of the magnetic shielding component to the corresponding permanent magnet. When the foldable terminal device is in the folded state, the magnetic shielding component can shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first ratio, and each pair of magnetic components can attract each other, giving the foldable terminal device a tight folding effect. When the foldable terminal device is in the unfolded state, the magnetic shielding component can shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second ratio, thereby effectively shielding the magnetic attraction force of the permanent magnet and preventing the permanent magnet from attracting magnetically conductive materials.

[0010] In some possible embodiments, when the foldable terminal device is in a folded state, the magnetic shield is located in a first position, such that the working surface of the corresponding permanent magnet is at least partially exposed. The magnetic shield blocks the magnetic attraction force generated by the corresponding permanent magnet that is lower than a first proportion. The working surface of the permanent magnet is the surface of the permanent magnet facing another magnetic component in the corresponding pair of magnetic components when the foldable terminal device is in a folded state. When the foldable terminal device is in an unfolded state, the magnetic shield is located in a second position, such that the working surface of the corresponding permanent magnet is covered by the magnetic shield. The magnetic shield blocks the magnetic attraction force generated by the corresponding permanent magnet that is higher than a second proportion.

[0011] Therefore, the surfaces of the permanent magnet other than the working surface can be shielded with magnetic shielding material beforehand. The working surface of the permanent magnet can be covered or uncovered by sliding the magnetic shielding component to optimize the magnetic circuit of the permanent magnet. When the foldable terminal device is in the folded state, the magnetic shielding component is in the first position, and at least part of the working surface of the corresponding permanent magnet is exposed without being covered by the magnetic shielding component. This allows the magnetic shielding component to block the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first proportion. Therefore, the first and second magnetic components of each pair of magnetic components can attract each other, and the foldable terminal device has a tight folding effect. When the foldable terminal device is in the unfolded state, the magnetic shielding component is in the second position, and the working surface of the corresponding permanent magnet is covered by the magnetic shielding component. The magnetic shielding component blocks the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second proportion, so as to effectively shield the magnetic attraction force of the permanent magnet and prevent the permanent magnet from attracting magnetically conductive materials.

[0012] In some possible embodiments, the target body is provided with a first sink, and at least a corresponding permanent magnet is located in the first sink with the working surface of the permanent magnet facing the opening of the first sink. At least a second position is the position corresponding to the permanent magnet at the opening of the first sink. The magnetic shield is a portion of the opening of the first sink that is slidably covered. When the magnetic shield is in the second position, the magnetic shield is covered on the opening of the first sink and covers the working surface of the corresponding permanent magnet to shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second proportion.

[0013] Therefore, a first sink is provided on the target body, and at least a permanent magnet is placed in the first sink. Magnetic shielding material can be placed in the first sink to shield the other surfaces of the permanent magnet except for the working surface. The working surface of the permanent magnet faces the opening of the first sink. The magnetic shield is a portion of the opening of the first sink that is slidably covered. When the magnetic shield is in the second position, it covers the opening of the first sink and the working surface of the permanent magnet to shield the magnetic attraction force generated by the permanent magnet that is higher than the second proportion, thereby improving the flatness of the foldable terminal device.

[0014] In some possible embodiments, the first position is a position offset from the position of the corresponding permanent magnet. When the magnetic shield moves to the first position, the magnetic shield is offset from the working surface of the corresponding permanent magnet to expose at least a portion of the working surface of the corresponding permanent magnet. The magnetic shield blocks the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first proportion.

[0015] Therefore, the first position is also set on the opening of the first sink. The magnetic shield can slide on the opening to switch between the first position and the second position, which enriches the setting methods of the magnetic shield and the permanent magnet.

[0016] In some possible embodiments, the target body is provided with a guide structure located in the moving direction of the magnetic shielding member moving between a first position and a second position. The magnetic shielding member is slidably disposed on the guide structure and switches between the first position and the second position under the guidance of the guide structure.

[0017] Therefore, the movement of the magnetic shielding component can be guided by the guiding structure, thereby improving the accuracy of the magnetic shielding component's movement.

[0018] In some possible embodiments, the dimension of the opening of the first sink along the moving direction is larger than the dimension of the working surface of the permanent magnet along the moving direction, and larger than the dimension of the magnetic shield along the moving direction. The first position is the position where the opening of the first sink is offset from the position of the corresponding permanent magnet. The guide structure includes the groove edge inside the first sink. The magnetic shield is disposed inside the first sink and located on one side of the first sink adjacent to the opening. The magnetic shield is slidably engaged with the groove edge and switches between the first position and the second position under the guidance of the groove edge.

[0019] Therefore, by using the edge of the first sink as a guide structure, and placing the magnetic shield inside the first sink and on one side adjacent to the opening of the first sink, the outer surface of the magnetic shield can be flush with the surface of the target body, thereby improving the flatness of the foldable terminal device.

[0020] In some possible embodiments, a limiting structure is provided in the first sink, and when the foldable terminal device is in the unfolded state, the edge of the magnetic shielding component contacts the limiting structure to form a stop.

[0021] Therefore, within the first settling tank, a limiting structure is provided in the direction from the first position to the second position of the magnetic shielding component. This can limit the movement of the magnetic shielding component under the guidance of the guiding structure within the first settling tank, thereby further improving the operational accuracy of the magnetic shielding component.

[0022] In some possible embodiments, the foldable terminal device includes a mechanical linkage mechanism connected between the magnetic shield and the rotating structure of the foldable terminal device. When the foldable terminal device is folded or unfolded, the magnetic shield is automatically triggered to switch positions between a first position and a second position.

[0023] Therefore, through the mechanical linkage mechanism, the magnetic shielding component can be automatically triggered to switch between the first and second positions when the foldable terminal device is folded or unfolded, which is more reliable and durable than electromagnetic drive.

[0024] In some possible embodiments, the rotating structure is a rotating shaft, and a mechanical linkage mechanism is connected between the magnetic shield and the rotating shaft. When the rotating shaft rotates, it is driven to switch between a first position and a second position.

[0025] Therefore, the rotating structure is a rotating shaft, and the magnetic shielding component is connected to the rotating shaft through a mechanical linkage mechanism. During the unfolding or folding of the foldable terminal device, the rotating shaft will rotate. The rotation of the rotating shaft will drive the magnetic shielding component to switch between the first position and the second position through the mechanical linkage mechanism. The rotation of the rotating shaft is cleverly utilized, and no additional driving component is required. Compared with electromagnetic drive, it can save power consumption and increase structural reliability.

[0026] In some possible embodiments, the rotating structure is a hinge, and a mechanical linkage mechanism is connected between the magnetic shield and the hinge, which is driven to switch between a first position and a second position when the hinge is in motion.

[0027] Thus, the rotating structure is a hinge, and the magnetic shielding component is connected to the hinge through a mechanical linkage mechanism. During the unfolding or folding of the foldable terminal device, there will be relative movement between different components of the hinge. The movement of the hinge components drives the magnetic shielding component to switch between the first and second positions through the mechanical linkage mechanism. This cleverly utilizes the movement of the hinge components, eliminating the need for additional driving components. Compared with electromagnetic drive, this can save power consumption and increase structural reliability.

[0028] In some possible embodiments, the mechanical linkage mechanism includes:

[0029] Traction component;

[0030] Reset elastic element;

[0031] The rotating structure, in conjunction with the movement of the traction component, drives the magnetic shielding component to the first position.

[0032] The rotating structure, in conjunction with the movement of the reset elastic element, drives the magnetic shielding element to the second position.

[0033] Therefore, by using the rotation of the rotating structure in conjunction with the traction and reset elastic components to drive the magnetic shielding component to switch between the first and second positions during the unfolding or folding of the foldable terminal device, the structure can be simplified, power consumption reduced, and structural reliability improved.

[0034] In some possible embodiments, the traction element is a flexible traction rope, and the reset elastic element is a compression spring, the preload of which is opposite to the tension of the traction rope.

[0035] Therefore, the traction component is a flexible traction rope, and the reset elastic component is a compression spring. The preload direction is opposite to the tension direction of the traction rope, which can simplify the structure and reduce costs.

[0036] In some possible embodiments, the magnetic shielding includes a first connecting end and a second connecting end disposed opposite to each other, a traction member is connected between the rotating structure and the first connecting end of the magnetic shielding, and a reset elastic member is connected to the second connecting end of the magnetic shielding and the side of the target body that is away from the rotating structure.

[0037] Therefore, by placing the traction component and the reset elastic component at opposite ends of the magnetic shield, the magnetic shield is subjected to more uniform force, and the motion is more stable.

[0038] In some possible embodiments, the target body is provided with a first sink and a second sink communicating with the first sink. At least the permanent magnet and the magnetic shield are located in the first sink, the traction member is located in the second sink and connected between the rotating structure and the magnetic shield, and the reset elastic member is located in the first sink and connected to the magnetic shield and the side of the first sink away from the second sink.

[0039] Therefore, by setting the shape and size of the first and second sinks according to the structure of the permanent magnet, magnetic shield, traction component, and reset elastic component, the structural compactness can be improved.

[0040] In some possible embodiments, a fixing rod is provided on the side of the first settling tank opposite to the second settling tank, and one end of the reset elastic element is connected to the fixing rod.

[0041] Therefore, by setting a fixing rod on the side of the first settling tank away from the second settling tank, and connecting one end of the reset elastic element to the fixing rod, the installation of the reset elastic element is more stable, reliable, and convenient.

[0042] In some possible embodiments, a limiting structure is provided in the first settling tank, and a fixing rod is connected to one side or opposite sides of the limiting structure.

[0043] Therefore, by defining the positional relationship between the limiting structure and the fixing rod, the fixing rod can be directly fixed to the side of the limiting structure. Based on the distance between the fixing rod and the side wall of the first sinking trough facing away from the second sinking trough, it is easier to connect the reset elastic element to the fixing rod, thus increasing the ease of installation.

[0044] In some possible embodiments, the rotating structure is a hinge, which includes a swing arm slider. A traction member is connected between the magnetic shield and the swing arm slider. During the folding or unfolding of the foldable terminal device, the swing arm slider slides relative to the target body in the moving direction of the magnetic shield, thereby causing the magnetic shield to switch between a first position and a second position.

[0045] Therefore, the swing motion of the magnetic shielding component and the swing arm slider of the rotating structure can be linked. During the folding process of the foldable terminal device, the swing arm slider moves away from the target body, thus driving the magnetic shielding component to move towards the hinge to the first position, thereby opening the working surface of the permanent magnet. Conversely, during the unfolding process of the foldable terminal device, the swing arm slider retracts towards the target body, thereby linking the magnetic shielding component to move away from the rotating structure to the second position, thereby covering the working surface of the permanent magnet and achieving the purpose of shielding the magnetic field lines of the permanent magnet. The structure is simple, requires no electric drive, saves power consumption, and has low cost.

[0046] In some possible embodiments, the hinge includes a door panel that is fixedly connected to the target body. The door panel has a slot on the side opposite to the target body. The rocker arm slider includes a sliding part that is inserted into the slot. A traction member is connected to the sliding part.

[0047] Therefore, the swing motion of the magnetic shielding component and the swing arm slider of the rotating structure can be linked. During the folding process of the foldable terminal device, the swing arm slider extends relative to the door panel, that is, during the folding process, the swing arm slider moves away from the door panel, thus driving the magnetic shielding component to move closer to the rotating structure to the first position, thereby opening the working surface of the permanent magnet. Conversely, during the unfolding process of the foldable terminal device, the swing arm slider retracts towards the door panel, that is, during the unfolding process, the swing arm slider moves closer to the door panel, thus linking the magnetic shielding component to move away from the rotating structure to the second position, thereby covering the working surface of the permanent magnet and achieving the purpose of shielding the magnetic field lines of the permanent magnet. The structure is simple, requires no electric drive, saves power consumption, and is low in cost. Moreover, the insertion slot can guide the movement of the swing arm slider, making the movement path of the swing arm slider more accurate and improving the reliability of operation.

[0048] In some possible embodiments, the target body is provided with a first recess and a second recess communicating with the first recess. At least the permanent magnet and the magnetic shield are located in the first recess. The traction member is located in the second recess and connected between the rotating structure and the magnetic shield. The reset elastic member is located in the first recess and connected to the magnetic shield and the side of the first recess away from the second recess. The door panel is provided with a through groove corresponding to the sliding part. The through groove communicates with the insertion groove. The through groove corresponds to the second recess. The traction member is connected to the part of the sliding part exposed from the through groove.

[0049] Therefore, by setting a through groove at the position of the sliding part of the door panel, the through groove is connected to the insertion groove, and the through groove corresponds to the second recessed groove. Thus, the traction member is connected to the part of the sliding part exposed from the through groove, simplifying the connection structure between the swing arm slider, the door panel and the traction member.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this application.

[0064] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0065] It should be understood that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0066] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0067] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The terms “an,” “a,” or “the,” as used herein, do not indicate a limitation of quantity, but are merely used to indicate the presence of at least one.

Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0068] To ensure a tight folding effect, foldable terminal devices require one or more pairs of magnets placed inside the frame to provide magnetic attraction when folded, helping to achieve stable folding. However, when the terminal is unfolded, these magnets easily attract small magnetic particles, which can easily compress and damage the surface of the foldable terminal.

[0069] Therefore, this application provides a foldable terminal device, including:

[0070] Rotating structure;

[0071] The first body part and the second body part are rotatably connected by a rotating structure;

[0072] At least one pair of magnetic components, each pair of magnetic components includes a first magnetic component and a second magnetic component, and the first magnetic component and the second magnetic component of each pair of magnetic components are respectively disposed on a first body part and a second body part. When the first body part and the second body part are in a folded state, the first magnetic component and the second magnetic component of each pair of magnetic components are magnetically connected. When the first body part and the second body part are in an unfolded state, the first magnetic component and the second magnetic component of each pair of magnetic components are separated from each other. At least one of the first magnetic component and the second magnetic component of each pair of magnetic components is a permanent magnet.

[0073] At least one magnetic shielding element is provided, each magnetic shielding element being disposed on the target body part at a position corresponding to at least one permanent magnet. The target body part is a body part provided with permanent magnets. When the foldable terminal device switches between a folded state and an unfolded state, the position of the magnetic shielding element switches between a first position and a second position on the corresponding target body part to shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than a first proportion or to shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than a second proportion, wherein the first proportion is less than the second proportion.

[0074] Therefore, during the unfolding or folding process of the foldable terminal device, this application can switch the position of the magnetic shielding component, thereby changing the shielding ratio of the magnetic attraction force of the magnetic shielding component to the corresponding permanent magnet. When the foldable terminal device is in the folded state, the magnetic shielding component can shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first ratio, and each pair of magnetic components can attract each other, so that the foldable terminal device has a tight folding effect. When the foldable terminal device is in the unfolded state, the magnetic shielding component can shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second ratio, so as to effectively shield the magnetic attraction force of the corresponding permanent magnet and prevent the permanent magnet from attracting magnetically conductive materials.

[0075] Please refer to Figure 1 , Figure 1This is a schematic diagram of the permanent magnet 300 in one embodiment of this application. The permanent magnet 300 has a working surface and a non-working surface. The non-working surface of the permanent magnet 300 can be covered by an effective magnetic shielding material 400, which can be, but is not limited to, soft iron, nanocrystalline magnetic shielding material, etc. Therefore, the non-working surface of the permanent magnet 300 is shielded and cannot emit magnetic field lines to the outside. The working surface of the permanent magnet 300 can be covered or opened by a magnetic shielding component (not shown). When the working surface of the permanent magnet 300 is covered by the magnetic shielding component, it cannot emit magnetic field lines to the outside due to the shielding. However, when the working surface of the permanent magnet 300 is not covered by the magnetic shielding component, it can emit magnetic field lines to the outside. In some embodiments, the permanent magnet 300 includes a bottom surface 3001, a top surface 3002, and a side surface 3003, with the side surface 3003 connecting the bottom surface 3001 and the top surface 3002. The bottom surface 3001 and side surface 3003 are non-working surfaces, while the top surface 3002 is the working surface. When the magnetic shielding covers the top surface 3002, the permanent magnet 300 cannot emit magnetic field lines to the outside. When the magnetic shielding is offset from the top surface 3002, the permanent magnet 300 can emit magnetic field lines to the outside. In other embodiments, the bottom surface 3001 and top surface 3002 can be non-working surfaces, and the side surface 3003 can be the working surface, or the bottom surface 3001 can be the working surface, and the top surface 3002 and side surface 3003 can be non-working surfaces, etc. The specific configuration can be set according to actual needs and is not limited here. In this embodiment, the top surface 3002 is the working surface.

[0076] Please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the foldable terminal device 200 provided in the embodiments of this application in its unfolded state. Figure 3 This is a schematic diagram of the foldable terminal device 200 provided in this application embodiment in a folded state. The foldable terminal device 200 can be an electronic product, including but not limited to mobile phones, laptops, cameras, drones, desk lamps, etc.; the foldable terminal device 200 can also be a non-electronic product, including but not limited to Bluetooth headset cases, glasses cases, etc. Figure 2 as well as Figure 3 In the embodiment shown, the foldable terminal device 200 is a foldable screen mobile phone.

[0077] The foldable terminal device 200 includes a first body part 201a, a second body part 201b, and a rotating structure 203. The first body part 201a and the second body part 201b are rotatably connected through the rotating structure 203.

[0078] For details, please refer to Figure 2 and Figure 3The specific names of the first body part 201a and the second body part 201b are related to the actual application scenario of the foldable terminal device 200. For example, when the foldable terminal device 200 is a foldable screen phone, both the first body part 201a and the second body part 201b are the parts where the screen is located; when the foldable terminal device 200 is a laptop computer, the first body part 201a can be the part where the screen is located, and the second body part 201b can be the part where the keyboard is located. Figure 2 The angle between the first body part 201a and the second body part 201b of the mobile phone shown is 180° (i.e., the screen of the mobile phone is in the open state). Figure 3 The angle between the first body part 201a and the second body part 201b of the mobile phone shown is 0° (that is, the screen of the mobile phone is in a closed state).

[0079] It is understandable that when the foldable terminal device 200 is a three-fold or multi-fold device, the first body part 201a or the second body part 201b itself can also be a foldable body part, and this is not limited here.

[0080] In some embodiments, the foldable terminal device 200 further includes at least one pair of magnetic elements 204. Each pair of magnetic elements 204 includes a first magnetic element 2041 and a second magnetic element 2042. The first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are respectively disposed on the first body portion 201a and the second body portion 201b. When the first body portion 201a and the second body portion 201b are in the folded state, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are magnetically connected. When the first body portion 201a and the second body portion 201b are in the unfolded state, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are separated from each other.

[0081] For details, please refer to Figure 4 In this embodiment, the foldable terminal device 200 includes two pairs of magnetic elements 204. One pair of magnetic elements 204 has a first magnetic element 2041 and a second magnetic element 2042 respectively disposed at the top ends of the first body portion 201a and the second body portion 201b. The other pair of magnetic elements 204 has a first magnetic element 2041 and a second magnetic element 2042 respectively disposed at the bottom ends of the first body portion 201a and the second body portion 201b. It is understood that in other embodiments, the magnetic elements 204 are not limited to two pairs, but may be one pair or more pairs; this is not limited here.

[0082] Therefore, when the foldable terminal device 200 is in the folded state, that is, when the first body part 201a and the second body part 201b are stacked and the angle between them is 0 degrees, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are magnetically attracted. When the foldable terminal device 200 is in the unfolded state, that is, when the first body part 201a and the second body part 201b are laid flat and the angle between them is 180 degrees, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are separated from each other.

[0083] In some embodiments, the foldable terminal device 200 is an inward-folding product. For example, when the foldable terminal device 200 is a mobile phone, the side of the foldable terminal device 200 with the screen folds inward, and when the foldable terminal device 200 is in the folded state, the screen is in a folded and fitted state. The first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 are disposed on the side of the foldable terminal device 200 with the screen. Preferably, the first magnetic element 2041 is disposed on the side of the middle frame of the first body part 201a near the screen, and the second magnetic element 2042 is disposed on the side of the middle frame of the second body part 201b near the screen. In this way, when the foldable terminal device 200 is in the folded state, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 can be magnetically attracted, with strong magnetic attraction and good attraction effect.

[0084] In some embodiments, at least one of the first magnetic element 2041 and the second magnetic element 2042 in each pair of magnetic elements 204 is a permanent magnet. The other of the first magnetic element 2041 and the second magnetic element 2042 in each pair of magnetic elements 204 can be a permanent magnet or a magnetic element made of a magnetically conductive material, which can be, but is not limited to, iron. In this embodiment, both the first magnetic element 2041 and the second magnetic element 2042 in each pair of magnetic elements 204 are permanent magnets.

[0085] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the foldable terminal device 200 in its unfolded state according to an embodiment of this application. Figure 6This is a schematic diagram of the foldable terminal device 200 in its folded state according to an embodiment of this application. The foldable terminal device 200 also includes at least one magnetic shielding member 205. Each magnetic shielding member 205 is disposed on a target body portion corresponding to at least one permanent magnet. The target body portion is a first body portion 201a and / or a second body portion 201b provided with permanent magnets. There is a corresponding relationship between at least one magnetic shielding member 205 and at least one target body portion. For example, in this embodiment, the first magnetic member 2041 and the second magnetic member 2042 of each pair of magnetic members 204 are both permanent magnets. Correspondingly, the first body portion 201a and the second body portion 201b are... b are all target body parts, and each permanent magnet is provided with a corresponding magnetic shield 205. Therefore, the permanent magnet, the magnetic shield 205 and the target body part have a corresponding relationship. When the foldable terminal device 200 switches between the folded state and the unfolded state, the position of the magnetic shield 205 switches between the first position a and the second position b of the corresponding target body part, so as to shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first proportion or shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second proportion. The first proportion is less than the second proportion.

[0086] Each magnetic shield 205 may correspond to the position of one or more permanent magnets disposed on the target body. In this embodiment, each magnetic shield 205 may correspond to the position of one permanent magnet. In other embodiments, each magnetic shield 205 may correspond to the position of multiple permanent magnets, and this is not limited here.

[0087] The first percentage can be, but is not limited to, 20%, such as 20%, 10%, 5%, 0%, etc., and the second percentage can be, such as 80%, 85%, 90%, 95%, 100%, etc. It is understood that in other embodiments, the first percentage can be a higher value, as long as it ensures a tight folding effect when the foldable terminal device 200 is in the folded state, and the second percentage can be a lower value, as long as it ensures that the foldable terminal device 200 does not attract magnetic materials when unfolded.

[0088] Therefore, during the unfolding or folding process of the foldable terminal device 200, this application can link the magnetic shielding component 205 to switch positions, thereby changing the shielding ratio of the magnetic attraction force of the magnetic shielding component 205 on the corresponding permanent magnet. When the foldable terminal device 200 is in the folded state, the magnetic shielding component 205 can shield the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first ratio, and each pair of magnetic components 204 can attract each other, so that the foldable terminal device 200 has a tight folding effect. When the foldable terminal device 200 is in the unfolded state, the magnetic shielding component 205 can shield the magnetic attraction force generated by the corresponding permanent magnet that is higher than the second ratio, so as to effectively shield the magnetic attraction force of the permanent magnet and prevent the permanent magnet from attracting magnetically conductive materials.

[0089] In some embodiments, please refer to Figure 5 and Figure 6 When the foldable terminal device 200 is in the folded state, the magnetic shield 205 is located at the first position a, so that at least part of the working surface of the corresponding permanent magnet is exposed. The magnetic shield 205 shields the magnetic attraction force generated by the corresponding permanent magnet that is lower than the first proportion. The working surface of the permanent magnet is the surface of the permanent magnet facing another magnetic element in the corresponding magnetic pair 204 when the foldable terminal device 200 is in the folded state. When the foldable terminal device 200 is in the unfolded state, the magnetic shield 205 is located at the second position b, so that the working surface of the permanent magnet is covered by the magnetic shield 205. The magnetic shield 205 shields the magnetic attraction force generated by the permanent magnet that is higher than the second proportion.

[0090] In this embodiment, the magnetic shield 205 is located at the first position a, where the working surface of the permanent magnet is fully exposed, and the magnetic shield 205 shields 0% of the magnetic attraction force generated by the permanent magnet. In the second position b, the magnetic shield 205 completely covers the working surface of the permanent magnet, and the magnetic shield 205 shields 100% of the magnetic attraction force generated by the permanent magnet. In other embodiments, the sizes of the first and second ratios can be adjusted according to actual needs.

[0091] Therefore, the surfaces of the permanent magnet other than the working surface can be shielded with magnetic shielding material beforehand. The working surface of the permanent magnet can be covered or uncovered by the sliding switching position of the magnetic shielding component 205, thereby optimizing the magnetic circuit of the permanent magnet. When the foldable terminal device 200 is in the folded state, the magnetic shielding component 205 is located in the first position a, and at least part of the working surface of the corresponding permanent magnet is exposed without being covered by the magnetic shielding component 205, so that the magnetic shielding component 205 shields less than a first proportion of the magnetic attraction force generated by the corresponding permanent magnet. Magnetic attraction, therefore, the first magnetic element 2041 and the second magnetic element 2042 of each pair of magnetic elements 204 can attract each other, and the foldable terminal device 200 has a tight folding effect; when the foldable terminal device 200 is in the unfolded state, the magnetic shield 205 is located in the second position b, so that the working surface of the permanent magnet is covered by the magnetic shield 205. The magnetic shield 205 shields the magnetic attraction force generated by the permanent magnet that is higher than the second proportion, so as to effectively shield the magnetic attraction force of the permanent magnet and prevent the permanent magnet from attracting magnetic materials.

[0092] In some embodiments, the magnetic shielding component 205 is a one-piece plate structure. In other embodiments, the magnetic shielding component 205 can be a multi-plate assembly structure with separate components. For example, the magnetic shielding component 205 is composed of two or more plate structures. When the two or more plate structures are assembled together, the magnetic shielding component 205 can shield the working surface of the permanent magnet. When the two or more plate structures are separated, the magnetic shielding component 205 can open the working surface of the permanent magnet.

[0093] In some embodiments, the magnetic shield 205 can be connected to the rotating structure 203 of the foldable terminal device 200 through its own structure. For example, the magnetic shield 205 can be extended and connected to the rotating structure 203 of the foldable terminal device 200, or the magnetic shield 205 can be large enough to be directly connected to the rotating structure 203 of the foldable terminal device 200.

[0094] In some embodiments, please refer to Figure 5 and Figure 6 The foldable terminal device 200 also includes a mechanical linkage mechanism 206, which is connected between the magnetic shield 205 and the rotating structure 203 of the foldable terminal device 200. When the foldable terminal device 200 is folded or unfolded, the magnetic shield 205 is automatically triggered to switch positions between the first position a and the second position b.

[0095] Thus, through the mechanical linkage mechanism 206, the magnetic shield 205 can be automatically triggered to switch positions between the first position a and the second position b when the foldable terminal device 200 is folded or unfolded, which is more reliable and durable than electromagnetic drive.

[0096] It should be noted that during the transition of the foldable terminal device 200 from a folded state to an unfolded state, the rotating structure 203 can trigger the mechanical linkage mechanism 206 to move the magnetic shielding component 205 from a first position a to a second position b. Similarly, during the transition from an unfolded state to a folded state, the rotating structure 203 can trigger the mechanical linkage mechanism 206 to move the magnetic shielding component 205 from a second position b to a first position a, thus switching the position of the magnetic shielding component 205 between the first position a and the second position b. Therefore, the mechanical linkage mechanism 206 is associated with the folding and unfolding process of the foldable terminal device 200. That is, during the transition from a folded state to an unfolded state or vice versa, the relative movement of the components of the rotating structure 203 can be transmitted to the magnetic shielding component 205 through the mechanical linkage mechanism 206, causing the magnetic shielding component 205 to switch between the first position a and the second position b.

[0097] In some embodiments, the rotating structure 203 is a rotating shaft, and the first body part 201a and the second body part 201b are rotatably connected via the rotating shaft. The magnetic shield 205 is connected to the rotating shaft via a mechanical linkage mechanism 206, and is driven to switch positions between a first position a and a second position b when the rotating shaft rotates. Therefore, the mechanical linkage mechanism 206 can be associated with the rotational movement of the rotating shaft. The rotational movement of the rotating shaft drives the mechanical linkage mechanism 206, which in turn drives the magnetic shield 205 to move, so as to convert the rotational movement into linear movement of the magnetic shield 205 between the first position a and the second position b, thereby driving the magnetic shield 205 to switch positions between the first position a and the second position b.

[0098] In other embodiments, the rotating structure 203 is a hinge, and the first body part 201a and the second body part 201b are rotatably connected by the hinge. The magnetic shield 205 is connected to the hinge via a mechanical linkage mechanism 206, and is driven to switch positions between the first position a and the second position b when the hinge is in motion. Therefore, the mechanical linkage mechanism 206 can be associated with the relative motion between the hinge components. The relative motion between the hinge components drives the mechanical linkage mechanism 206, which in turn drives the magnetic shield 205 to move, so as to convert the relative motion between the hinge components into linear motion of the magnetic shield 205 between the first position a and the second position b, thereby driving the magnetic shield 205 to switch positions between the first position a and the second position b.

[0099] In other embodiments, the mechanical linkage mechanism 206 may be a transmission mechanism, and the foldable terminal device 200 may also include a driving component, which may be, but is not limited to, a cylinder, a motor, etc. The foldable terminal device 200 may also include an opening and closing sensor. When the opening and closing sensor detects the opening and closing action of the foldable terminal device 200, it generates a corresponding control command to control the driving component to drive the mechanical linkage mechanism 206 and thus drive the magnetic shielding component 205 to move.

[0100] It is understood that in the embodiments where the rotating structure 203 is a rotating shaft and connected to the mechanical linkage mechanism 206, and in the embodiments where the rotating structure 203 is a hinge and connected to the mechanical linkage mechanism 206, the rotating structure 203 essentially acts as a driving element. Therefore, compared with electromagnetic drive, it can reduce costs, save power consumption, and save internal layout space of the foldable terminal device 200.

[0101] In this embodiment, both pairs of magnetic components 204 of the foldable terminal device 200 are permanent magnets. Therefore, the foldable terminal device 200 includes four magnetic shielding components 205 and four mechanical linkage mechanisms 206. The four magnetic shielding components 205, the four mechanical linkage mechanisms 206, and the four permanent magnets have a one-to-one correspondence. In other embodiments, the relationship between the permanent magnets and the magnetic shielding components 205 may be many-to-one, and the relationship between the magnetic shielding components 205 and the mechanical linkage mechanisms 206 may be one-to-one, etc., which are not limited here.

[0102] In some embodiments, the mechanical linkage mechanism 206 includes a traction member 2061 and a reset elastic member 2062. The rotating structure 203, in coordination with the movement of the traction member 2061, drives the magnetic shield 205 to a first position a; the rotating structure 203, in coordination with the movement of the reset elastic member 2062, drives the magnetic shield 205 to a second position b.

[0103] Therefore, by coordinating the movement of the rotating structure 203 during the unfolding or folding of the foldable terminal device 200 with the traction member 2061 and the reset elastic member 2062 to drive the magnetic shielding member 205 to switch positions between the first position a and the second position b, the structure can be simplified, power consumption reduced, and structural reliability improved.

[0104] In some embodiments, the traction member 2061 is a flexible traction rope, and the reset elastic member 2062 is a compression spring, the direction of which is opposite to the direction of the tension of the traction rope.

[0105] For details, please refer to Figure 5 and Figure 6The traction member 2061 can be a traction rope, which is not an elastic rope, such as a nylon rope, and its elastic deformation is very small. The reset elastic member 2062 can be a compression spring, etc. Taking the traction member 2061 and the reset elastic member 2062 provided on the first body part 201a as an example, during the folding process of the foldable terminal device 200, the movement of a local structure of the rotating structure 203 away from the first body part 201a causes the traction member 2061 to pull the magnetic shield 205 to move closer to the rotating structure 203, that is, from the second position b to the first position a, so as to open the working surface of the permanent magnet (i.e., the first magnetic member 2041) and make the reset elastic member 2062 in a stretched state. During the unfolding process of the foldable terminal device 200, the local structure of the rotating structure 203 moves closer to the first body part 201a. The local structure of the rotating structure 203 will no longer pull the traction member 2061. The elastic restoring force of the reset elastic member 2062 can thus drive the magnetic shielding member 205 to move from the first position a to the second position b, so that the magnetic shielding member 205 covers the working surface of the permanent magnet (i.e., the first magnetic member 2041).

[0106] Thus, by combining the movement of the magnetic shield 205 between the first position a and the second position b with the local structure of the rotation structure 203 during the unfolding or folding process of the foldable terminal device 200, the traction member 2061 is a flexible traction rope, and the reset elastic member 2062 is a compression spring, the preload direction of which is opposite to the tension direction of the traction rope, which can simplify the structure and reduce costs.

[0107] In some embodiments, taking the traction member 2061 and the reset elastic member 2062 provided on the first body part 201a as examples, the traction member 2061 is connected between the rotating structure 203 and one end of the corresponding magnetic shield 205, and the reset elastic member 2062 can be located on the side of the magnetic shield 205 and the first body part 201a away from the rotating structure 203.

[0108] In other embodiments, the traction member 2061 is connected between one end of the rotating structure 203 and the corresponding magnetic shield 205, and the reset elastic member 2062 can also be located between the magnetic shield 205 and the rotating structure 203. During the folding process of the foldable terminal device 200, the reset elastic member 2062 is compressed by the magnetic shield 205. During the unfolding process of the foldable terminal device 200, the local structure of the rotating structure 203 will not continue to pull the traction member 2061. The elastic restoring force of the reset elastic member 2062 can drive the magnetic shield 205 to move from the first position a to the second position b, so that the magnetic shield 205 covers the working surface of the permanent magnet (i.e., the first magnetic member 2041).

[0109] In other embodiments, the mechanical linkage mechanism 206 does not need to be divided into a traction member 2061 and a reset elastic member 2062. Instead, it can be a rigid member connected between the rotating structure 203 and the magnetic shield 205. Therefore, when the foldable terminal device 200 is unfolded, the rotating structure 203 pushes the magnetic shield 205 from the first position a to the second position b through the mechanical linkage mechanism 206. During the folding process of the foldable terminal device 200, the rotating structure 203 pulls the magnetic shield 205 from the second position b to the first position a through the mechanical linkage mechanism 206.

[0110] The above describes three specific methods for moving the magnetic shielding component 205 between the first position a and the second position b using the mechanical linkage mechanism 206. It should be noted that there are actually other implementation methods for moving the magnetic shielding component 205 between the first position a and the second position b using the mechanical linkage mechanism 206, which are not limited here.

[0111] Depend on Figure 5 and Figure 6 It can be seen that the first position a is closer to the rotating structure 203 than the second position b. That is, the distance between the second position b and the connection position of the first body part and the second body part 201b (i.e., the position of the rotating structure 203) is smaller than the distance between the first position a and the connection position of the first body part and the second body part 201b.

[0112] Therefore, the first position a is closer to the connection position of the first body part and the second body part 201b than the second position b. This can match the swinging action of the rotating structure 203. During the folding process of the foldable terminal device 200, the magnetic shield 205 can be moved to the side closer to the rotating structure 203 to the first position a, thereby opening the working surface of the permanent magnet. Conversely, during the unfolding process of the foldable terminal device 200, the elastic restoring force of the reset elastic member 2062 can move the magnetic shield 205 to the side away from the rotating structure 203 to the second position b, thereby covering the working surface of the permanent magnet and achieving the purpose of shielding the magnetic field lines of the permanent magnet.

[0113] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the traction member 2061, the reset elastic member 2062, the magnetic shielding member 205, and the permanent magnet (first magnetic member 2041 or second magnetic member 2042) in the embodiments of this application.

[0114] During the unfolding process of the foldable terminal device 200, the reset elastic element 2062 pulls the magnetic shield 205 from the first position a to the second position b, so that the magnetic shield 205 covers the working surface of the permanent magnet (the first magnetic element 2041 or the second magnetic element 2042).

[0115] During the folding process of the foldable terminal device 200, the traction component 2061 pulls the magnetic shield 205 from the second position b to the first position a, so that the magnetic shield 205 is misaligned with the permanent magnet (the first magnetic component 2041 or the second magnetic component 2042). In this way, the working surface of the permanent magnet (the first magnetic component 2041 or the second magnetic component 2042) will not be blocked by the magnetic shield 205, and it can emit magnetic field lines normally.

[0116] Please refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 , Figure 8 This is a schematic diagram of the structure of a foldable terminal device 200 in one embodiment of this application. Figure 9 for Figure 8 A three-dimensional structural diagram of a local structure in the image. Figure 10 for Figure 9 A magnified view at point A. Figure 11 for Figure 10 The decomposition diagram in the image.

[0117] In some embodiments, the positional relationship between the permanent magnet (first magnetic element 2041), the magnetic shield 205, and the mechanical linkage mechanism 206 is illustrated using the first body portion 201a as an example. The target body portion has a first recess 2011, in which at least the permanent magnet (first magnetic element 2041) is located, with its working surface facing the opening of the first recess 2011. At least the second position b is a position at the opening of the first recess 2011 corresponding to the permanent magnet (first magnetic element 2041). The magnetic shield 205 is a portion of the opening of the first recess 2011 that is slidably covered. When the magnetic shield 205 is located at the second position b, it covers the opening of the first recess 2011 and the working surface of the permanent magnet to shield the magnetic attraction force generated by the permanent magnet (first magnetic element 2041) from a magnetic attraction force higher than the second proportion.

[0118] Therefore, a first sink 2011 is provided on the target body, and at least a permanent magnet is placed in the first sink 2011. Magnetic shielding material can be placed in the first sink 2011 to shield the other surfaces of the permanent magnet except for the working surface. The working surface of the permanent magnet faces the opening of the first sink 2011. The magnetic shielding component 205 is a partially slidable cover on the opening of the first sink 2011. When the magnetic shielding component 205 is in the second position b, it covers the opening of the first sink 2011 and the working surface of the permanent magnet to shield the magnetic attraction force generated by the permanent magnet that is higher than the second proportion, thereby improving the flatness of the foldable terminal device 200.

[0119] In some embodiments, the size of the first sink 2011 is just enough to accommodate the permanent magnet (first magnetic element 2041). The magnetic shield 205 can be disposed on the outside of the first sink 2011 and slidably connected to the surface of the target body. The projected area of ​​the magnetic shield 205 on the surface of the target body is greater than or equal to the area of ​​the opening of the first sink 2011. When the magnetic shield 205 is located in the second position b, the magnetic shield 205 just covers the opening of the first sink 2011 and covers the working surface of the permanent magnet. When the magnetic shield 205 is located in the first position a, the magnetic shield 205 and the opening of the first sink 2011 do not overlap at least partially or not overlap at all.

[0120] In other embodiments, the volume of the first sink 2011 is relatively large, and the projected area of ​​the magnetic shield 205 on the surface of the target body is smaller than the area of ​​the opening of the first sink 2011. Therefore, in addition to allowing the permanent magnet (first magnetic element 2041) to be accommodated, the first sink 2011 also provides space for the magnetic shield 205 to move. Therefore, the first position a and the second position b can both be positions corresponding to different positions of the opening of the first sink 2011. Specifically, the first position a is a position offset from the position of the permanent magnet, and the second position b is a position at the opening of the first sink 2011 corresponding to the permanent magnet (first magnetic element 2041). When the magnetic shield 205 moves to the first position a, the magnetic shield 205 is offset from the working surface of the permanent magnet to expose at least part of the working surface of the permanent magnet. The magnetic shield 205 shields the magnetic attraction force generated by the permanent magnet that is lower than the first proportion. When the magnetic shielding component 205 is located in the second position b, it covers the opening of the first sink 2011 and the working surface of the permanent magnet to shield the magnetic attraction force generated by the permanent magnet (first magnetic component 2041) that is higher than the second proportion. It is understood that in this case, the magnetic shielding component 205 can be disposed on the outside of the first sink 2011 and slidably connected to the surface of the target body, or the magnetic shielding component 205 can be disposed inside the first sink 2011 and located on one side of the first sink 2011 adjacent to the opening.

[0121] Thus, the first position a is also located on the opening of the first sink 2011. The magnetic shield 205 can switch between the first position a and the second position b by sliding on the opening, which enriches the arrangement of the magnetic shield 205 and the permanent magnet (first magnetic component 2041).

[0122] In some embodiments, the movement of the magnetic shield 205 requires a guide structure 2017, which can improve the accuracy of the movement of the magnetic shield 205. Specifically, taking the first body part 201a as the target body part as an example, the target body part is provided with a guide structure 2017. The guide structure 2017 is located in the movement direction of the magnetic shield 205 between the first position a and the second position b. The magnetic shield 205 is slidably disposed on the guide structure 2017 and switches positions between the first position a and the second position b under the guidance of the guide structure 2017.

[0123] Therefore, the movement of the magnetic shield 205 can be guided by the guide structure 2017, thereby improving the movement accuracy of the magnetic shield 205.

[0124] In some embodiments, please refer to Figure 11 The dimension of the opening of the first sink 2011 along the moving direction is greater than the dimension of the working surface of the permanent magnet along the moving direction, and greater than the dimension of the magnetic shield 205 along the moving direction. The first position a is the position where the opening of the first sink 2011 is offset from the position of the corresponding permanent magnet. The guide structure 2017 includes a groove edge in the first sink 2011. The magnetic shield 205 is disposed in the first sink 2011 and located on the side of the first sink 2011 adjacent to the opening. The magnetic shield 205 is slidably engaged with the groove edge and switches between the first position a and the second position b under the guidance of the groove edge.

[0125] Therefore, by using the groove edge of the first sink 2011 as the guide structure 2017, and the magnetic shield 205 is disposed in the first sink 2011 and located on one side of the first sink 2011 adjacent to the groove opening, the outer surface of the magnetic shield 205 can be flush with the surface of the target body, thereby improving the flatness of the foldable terminal device 200.

[0126] In other embodiments, the magnetic shield 205 may be disposed on the outside of the first sink 2011 and slidably connected to the surface of the target body, and the guide structure 2017 may be disposed on the surface of the target body, without limitation.

[0127] In some embodiments, a limiting structure 2013 is provided on the target body. When the foldable terminal device 200 is in the unfolded state, the magnetic shield 205 is located at the second position b, and the edge of the magnetic shield 205 contacts the limiting structure 2013 to form a stop. When the magnetic shield 205 is disposed in the first sink 2011 and located on one side of the first sink 2011 adjacent to the opening, the limiting structure 2013 can be disposed in the first sink 2011 and adjacent to the second position b. Alternatively, the magnetic shield 205 can be disposed on the outside of the first sink 2011 and slidably connected to the surface of the target body, and the limiting structure 2013 can be disposed on the surface of the target body outside the first sink 2011 and adjacent to the second position b.

[0128] Therefore, by setting a limiting structure 2013 in the direction of the magnetic shield 205 from the first position a to the second position b, the movement of the magnetic shield 205 can be limited, thereby further improving the operational accuracy of the magnetic shield 205.

[0129] In some embodiments, please refer to Figure 10 and Figure 11 The magnetic shielding component 205 includes a first connecting end 2051 and a second connecting end 2052 disposed opposite to each other. A traction member 2061 is connected between the rotating structure 203 and the first connecting end 2051 of the magnetic shielding component 205. A reset elastic member 2062 is connected to the second connecting end 2052 of the magnetic shielding component 205 and the side of the target body portion facing away from the rotating structure 203. Specifically, the reset elastic member 2062 may be located within the first sink 2011, connected to the second connecting end 2052 of the magnetic shielding component 205 and the side of the first sink 2011 facing away from the rotating structure. In other embodiments, the reset elastic member 2062 may be at least partially located outside the first sink 2011 and connected to the second connecting end 2052 of the magnetic shielding component 205 and the surface of the target body portion facing away from the rotating structure.

[0130] Thus, by placing the traction member 2061 and the reset elastic member 2062 at opposite ends of the magnetic shield 205, the magnetic shield 205 is subjected to more uniform force and the motion is more stable.

[0131] In some embodiments, when the reset elastic member 2062 is located in the first sink 2011, connected to the second connection end 2052 of the magnetic shield 205 and on the side of the first sink 2011 away from the rotating structure, a fixing rod 2014 is provided on the side of the first sink 2011 away from the rotating structure 203, and one end of the reset elastic member 2062 is connected to the fixing rod 2014.

[0132] Therefore, a fixing rod 2014 is provided on the side of the first settling tank 2011 away from the rotating structure 203, and one end of the reset elastic element 2062 is connected to the fixing rod 2014, making the installation of the reset elastic element 2062 more stable, reliable and convenient.

[0133] In some embodiments, when both a limiting structure 2013 and a fixing rod 2014 are provided in the first settling tank 2011, the fixing rod 2014 can be connected to one side or both opposite sides of the limiting structure 2013. In this embodiment, there are two reset elastic elements 2062 and two fixing rods 2014 connected to both opposite sides of the limiting structure 2013.

[0134] Therefore, by defining the positional relationship between the limiting structure 2013 and the fixing rod 2014, the fixing rod 2014 can be directly fixed to the side of the limiting structure 2013. The distance between the fixing rod 2014 and the side wall of the first recess 2011 facing away from the rotating structure 203 can be adjusted, making it easier to connect the reset elastic element 2062 to the fixing rod 2014 and increasing installation convenience. Moreover, the two reset elastic elements 2062 are reliably connected and can provide sufficient elastic restoring force.

[0135] In some embodiments, please refer to Figure 10 and Figure 11 The target body is provided with a first sink 2011 and a second sink 2018 connected to the first sink 2011. The traction member 2061 is located in the second sink 2018 and connected between the rotating structure 203 and the magnetic shield 205. The reset elastic member 2062 is located in the first sink 2011 and connected to the magnetic shield 205 and the side of the first sink 2011 opposite to the second sink 2018.

[0136] Therefore, by setting the shape and size of the first sink 2011 and the second sink 2018 according to the structure of the permanent magnet, the magnetic shield 205, the traction member 2061 and the reset elastic member 2062, the structural compactness can be improved.

[0137] In some embodiments, please refer to Figure 11 The magnetic shield 205 has a stepped portion 2053 at one end near the traction member 2061. A first connecting end 2051 is located on the stepped portion 2053. Preferably, the stepped portion 2053 is semi-circular. The first connecting end 2051 is circular. The diameter of the stepped portion 2053 is larger than the diameter of the first connecting end 2051.

[0138] In some embodiments, please refer to Figure 11 The second connecting end 2052 is a lug-shaped protrusion with a connecting hole 2054. The reset elastic element 2062 passes through the connecting hole 2054. This makes the connection more reliable.

[0139] In some embodiments, the rotating structure 203 is a hinge, which includes a swing arm slider. The traction member 2061 is connected between the magnetic shield 205 and the swing arm slider. During the folding or unfolding process of the foldable terminal device 200, the swing arm slider slides relative to the target body in the moving direction of the magnetic shield 205, thereby driving the magnetic shield 205 to switch positions between the first position a and the second position b.

[0140] Thus, the swinging motion of the magnetic shield 205 and the swing arm slider of the rotating structure 203 can be linked. During the folding process of the foldable terminal device 200, the swing arm slider moves away from the target body, thereby driving the magnetic shield 205 to move towards the hinge to the first position a, thereby opening the working surface of the permanent magnet. Conversely, during the unfolding process of the foldable terminal device 200, the swing arm slider retracts towards the target body, thereby driving the magnetic shield 205 to move away from the rotating structure to the second position b, thereby covering the working surface of the permanent magnet and achieving the purpose of shielding the magnetic field lines of the permanent magnet. The structure is simple, requires no electric drive, saves power consumption, and has low cost.

[0141] Specifically, referring to the figure, the rotating structure 203 includes a first swing arm slider 208 and a second swing arm slider 210. The first swing arm slider 208 is slidably connected to the first body portion 201a, and the second swing arm slider 210 is slidably disposed on the second body portion 201b. The first swing arm slider 208 and the second swing arm slider 210 are pivotally connected. It is understood that the pivotal connection between the first swing arm slider 208 and the second swing arm slider 210 can be a direct connection or an indirect connection, which is not limited here. The aforementioned swing arm slider can be either the first swing arm slider 208 or the second swing arm slider 210. It should be noted that, for ease of description, the following will refer to... Figure 8 , Figure 9 , Figure 10 and Figure 11The linkage principle between the magnetic shield 205, the mechanical linkage mechanism 206, and the rotating structure 203 is illustrated using the magnetic shield 205 and the mechanical linkage mechanism 206 located at the top of the first body part 201a as examples. In fact, the linkage principle between the other magnetic shield 205 and the other mechanical linkage mechanism 206 located at the top of the second body part 201b and the rotating structure 203 is the same as that between the magnetic shield 205 and the mechanical linkage mechanism 206 located at the top of the first body part 201a, and therefore will not be described again. When the foldable terminal device 200 is in the folded state, the first swing arm slider 208 is located on the side away from the first body part 201a, and the first swing arm slider 208 drives the corresponding magnetic shield 205 to move to the first position a through the corresponding traction member 2061; when the foldable terminal device 200 is in the unfolded state, the first swing arm slider 208 is located on the side close to the first body part 201a, and the reset elastic member 2062 drives the magnetic shield 205 to the second position b.

[0142] Thus, by sliding the swing arm slider relative to the target body in the moving direction of the magnetic shield 205, the magnetic shield 205 moves between the first position a and the second position b. The structure is simple, requires no electric drive, saves power consumption, and has low cost.

[0143] In some embodiments, the hinge includes a door panel that is fixedly connected to the target body. The door panel has a slot on the side opposite to the target body. The swing arm slider includes a sliding part that is inserted into the slot. A traction member is connected to the sliding part.

[0144] For details, please refer to Figure 8 , Figure 9 , Figure 10 and Figure 11The rotating structure 203 also includes a first door panel 207 and a second door panel 209. The first door panel 207 is connected to the first body part 201a, and a first swing arm slider 208 is slidably disposed on the first door panel 207. The second door panel 209 is connected to the second body part 201b, and a second swing arm slider 210 is slidably disposed on the second door panel 209. The aforementioned door panel can be either the first door panel 207 or the second door panel 209. The first door panel 207 has a first insertion groove 2071 on the side opposite to the corresponding first body part 201a. The first swing arm slider 208 includes a first sliding part 2081 and a first swing arm 2082. The first swing arm 2082 is relatively inclinedly connected to the side of the first sliding part 2081 opposite to the first body part 201a, and the first sliding part 2081 is inserted into the first insertion groove 2071. The second door panel 209 has a second insertion groove on the side opposite to the corresponding second body part 201b. The second swing arm slider 210 includes a second sliding part and a second swing arm. The second swing arm is connected to the side of the second sliding part opposite to the second body part at a relatively oblique angle. The second sliding part is inserted into the second insertion groove, wherein the insertion groove can be either the first insertion groove 2071 or the second insertion groove. The sliding part can be either the first sliding part or the second sliding part mentioned above. One traction member 2061 is connected to the first sliding part 2081, and the other traction member 2061 can be connected to the second sliding part, which will not be described in detail here.

[0145] Therefore, the swinging motion of the magnetic shield 205 and the swing arm slider of the rotating structure 203 can be linked. During the folding process of the foldable terminal device 200, the swing arm slider extends relative to the door panel, that is, during the folding process of the foldable terminal device 200, the swing arm slider moves away from the door panel, thus driving the magnetic shield 205 to move closer to the rotating structure 203 to the first position a, thereby opening the working surface of the permanent magnet. Conversely, during the unfolding process of the foldable terminal device 200, the swing arm slider retracts towards the door panel, that is, during the unfolding process of the foldable terminal device 200, the swing arm slider moves closer to the door panel, thereby linking the magnetic shield 205 to move away from the rotating structure 203 to the second position b, thereby covering the working surface of the permanent magnet, achieving the purpose of shielding the magnetic field lines of the permanent magnet. The structure is simple, requires no electric drive, saves power consumption, and has low cost. Moreover, the insertion slot can guide the movement of the swing arm slider, making the movement path of the swing arm slider more accurate and improving the reliability of operation. Furthermore, without any additional modifications to the rocker arm slider, the mechanical linkage mechanism 206 can be driven by the rocker arm slider, resulting in a simpler structure.

[0146] In some embodiments, a through groove is provided at the position of the sliding part of the door panel, the through groove is connected to the insertion groove, the through groove corresponds to the second recess 2018, and the traction member 2061 is connected to the part of the sliding part exposed from the through groove.

[0147] For details, please refer to Figure 10 The first door panel 207 also has a first through groove 2072 corresponding to the first insertion groove 2071. The first through groove 2072 penetrates one side surface of the first door panel 207 and communicates with the first insertion groove 2071. The first sliding part 2081 can then protrude from the first insertion groove 2071. The portion of the first sliding part 2081 protruding from the first through groove 2072 is provided with a connecting block 2083. A traction member 2061 is connected to the connecting block 2083. Correspondingly, the second door panel 209 also has a second through groove corresponding to the second insertion groove. The second through groove penetrates one side surface of the second door panel and communicates with the second insertion groove 1. The second sliding part can then protrude from the second insertion groove. The portion of the second sliding part protruding from the second through groove is provided with another connecting block. Another traction member 2061 is connected to this other connecting block. The through groove can be either the aforementioned first through groove or the second through groove, and correspondingly, the insertion groove can be either the aforementioned first insertion groove or the second insertion groove.

[0148] Next, we will introduce the specific structure of the electronic device 100 when the foldable terminal device 200 is the electronic device 100.

[0154] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0155] In some embodiments, the processor 110 may include one or more interfaces.

In some embodiments, the UART interface is typically used to connect the processor 110 and the wireless communication module 160. For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 via the UART interface to implement Bluetooth functionality. In some embodiments, the audio module 170 can transmit audio signals to the wireless communication module 160 via the UART interface to enable music playback through Bluetooth headphones.

[0160] The MIPI interface can be used to connect the processor 110 to peripheral devices such as the display screen 194 and the camera 193. The MIPI interface includes a camera serial interface (CSI) and a display serial interface (DSI). In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to enable the electronic device 100 to capture images. The processor 110 and the display screen 194 communicate via the DSI interface to enable the electronic device 100 to display images.

[0161] The GPIO interface can be configured via software. It can be configured as a control signal or a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 to a camera 193, a display screen 194, a wireless communication module 160, an audio module 170, a sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

[0162] USB port 130 is a USB standard compliant interface, specifically a Mini USB port, Micro USB port, USB Type-C port, etc. USB port 130 can be used to connect a charger to charge electronic device 100, and can also be used for data transfer between electronic device 100 and peripheral devices. It can also be used to connect headphones for audio playback. This interface can also be used to connect other electronic devices, such as AR devices.

[0163] It is understood that the interface connection relationships between the modules illustrated in the embodiments of the present invention are merely illustrative and do not constitute a structural limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0164] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 receives charging input from the wired charger via a USB interface 130. In some wireless charging embodiments, the charging management module 140 receives wireless charging input via the wireless charging coil of the electronic device 100. While charging the battery 142, the charging management module 140 can also supply power to the electronic device 100 via the power management module 141.

[0165] The power management module 141 connects the battery 142, the charging management module 140, and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140, providing power to the processor 110, internal memory 121, external memory, display screen 194, camera 193, and wireless communication module 160, etc. The power management module 141 can also monitor parameters such as battery capacity, battery cycle count, and battery health status (leakage current, impedance). In some other embodiments, the power management module 141 may also be located within the processor 110. In other embodiments, the power management module 141 and the charging management module 140 may be located in the same device.

[0166] The wireless communication function of electronic device 100 can be realized through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor and baseband processor, etc.

[0167] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 100 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with tuning switches.

[0168] The mobile communication module 150 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G, applied to the electronic device 100. The mobile communication module 150 may include at least one filter, switch, power amplifier, low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via antenna 1. In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0169] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through an audio device (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0170] The wireless communication module 160 can provide solutions for wireless communication applications on the electronic device 100, including wireless local area networks (WLANs) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signals, and sends the processed signal to processor 110. The wireless communication module 160 can also receive signals to be transmitted from processor 110, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0171] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 150, and antenna 2 is coupled to wireless communication module 160, enabling electronic device 100 to communicate with networks and other devices via wireless communication technology.

The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0173] Display screen 194 is used to display images, videos, etc. Display screen 194 includes a display panel.

[0174] Electronic device 100 can perform shooting functions through ISP, camera 193, video codec, GPU, display 194 and application processor.

[0175] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin parameters. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0176] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0177] Digital signal processors (DSPs) are used to process digital signals. Besides digital image signals, they can also process other digital signals. For example, when electronic device 100 selects a frequency, the DSP can perform Fourier transforms on the frequency energy.

[0178] Video codecs are used to compress or decompress digital video. Electronic device 100 may support one or more video codecs. Thus, electronic device 100 can play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

[0179] An NPU (Neural Processing Unit) is a computational processor for neural networks (NNs). By borrowing the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, it can rapidly process input information and continuously learn on its own. NPUs enable intelligent cognitive applications in electronic devices, such as image recognition, facial recognition, speech recognition, and text understanding.

[0180] The external storage interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external storage interface 120 to perform data storage functions. For example, music, video, and other files can be saved on the external memory card.

[0181] Internal memory 121 can be used to store computer executable program code, which includes instructions. Processor 110 executes various functional applications and data processing of electronic device 100 by running the instructions stored in internal memory 121. Internal memory 121 may include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function (such as sound playback, image playback, etc.), etc. The data storage area may store data created during the use of electronic device 100 (such as audio data, phonebook, etc.). Furthermore, internal memory 121 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc.

[0182] Electronic device 100 can implement audio functions, such as music playback and recording, through audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, and application processor.

[0183] The audio module 170 is used to convert digital audio information into analog audio signals for output, and also to convert analog audio input into digital audio signals. The audio module 170 can also be used for encoding and decoding audio signals. In some embodiments, the audio module 170 may be located in the processor 110, or some functional modules of the audio module 170 may be located in the processor 110.

[0184] The speaker 170A, also known as a "loudspeaker," is used to convert audio electrical signals into sound signals. The electronic device 100 can listen to music or make hands-free calls through the speaker 170A.

[0185] The receiver 170B, also known as the "earpiece," is used to convert audio electrical signals into sound signals. When the electronic device 100 answers a telephone call or voice message, the receiver 170B can be brought close to the ear to listen to the voice.

[0186] Microphone 170C, also known as a "microphone" or "voice transducer," is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak by bringing their mouth close to microphone 170C, inputting the sound signal into microphone 170C. Electronic device 100 may have at least one microphone 170C. In some embodiments, electronic device 100 may have two microphones 170C, which, in addition to collecting sound signals, can also perform noise reduction. In other embodiments, electronic device 100 may also have three, four, or more microphones 170C, which can collect sound signals, reduce noise, identify the sound source, and perform directional recording, etc.

[0187] The 170D headphone jack is used to connect wired headphones. The 170D headphone jack can be a USB 130 interface or a 3.5mm Open Mobile Terminal Platform (OMTP) standard interface, a CTIA (Cellular Telecommunications Industry Association of the USA) standard interface.

[0188] Pressure sensor 180A is used to sense pressure signals and convert them into electrical signals. In some embodiments, pressure sensor 180A can be disposed on display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may include at least two parallel plates with conductive material. When force is applied to pressure sensor 180A, the capacitance between the electrodes changes. Electronic device 100 determines the pressure intensity based on the change in capacitance. When a touch operation is applied to display screen 194, electronic device 100 detects the touch operation intensity based on pressure sensor 180A. Electronic device 100 can also calculate the touch position based on the detection signal from pressure sensor 180A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example: when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS is executed.

[0189] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 100.
