The foldable electronic device includes a folding screen and a middle frame, the middle frame supports the folding screen to switch between the folded state and the unfolded state.

[0004] The folding screen has a certain rebound force after folding, which is easy to cause a gap between the folding screens. In order to ensure that there is no gap after the folding screen is folded, a pair or multiple pairs of magnets are usually arranged at the corresponding positions on both sides of the folding screen after folding. However, the magnetic force generated by the magnets is fixed. In order to ensure the precise closing of the folding screen after folding, the magnetic force of the magnets is generally large, so that the force of the user when opening the folding screen is also large. At the same time, when the folding screen is closed to a small angle, the magnetic force between the magnets will gradually increase, which may cause the folding screen to suddenly close, affecting the user experience.

[0078] The electronic device of the present application will be described in detail below taking a foldable phone as an example.

[0079] FIG. 1 shows a structure diagram of an open state of an electronic device provided in the embodiments of the present application. Referring to FIG. 1, the electronic device 10 includes a first screen 1 and a second screen 2, and the first screen 1 and the second screen 2 are rotationally connected. For example, the first screen 1 and the second screen 2 can be connected through a folding shaft 3 (also referred to as a rotation shaft), and the presence of the folding shaft 3 enables the first screen 1 to move relative to the second screen 2 to switch between an open state and a closed state.

[0080] Please continue to refer to FIG. 1, the electronic device 10 is in the open state, the distance between the first screen 1 and the second screen 2 is far, the electronic device 10 is in the process of switching from the open state to the closed state, the first screen 1 is folded in the direction of the arrow shown in FIG. 1, the inner side of the first screen 1 is closer and closer to the inner side of the second screen 2, until the first screen 1 and the second screen 2 are in contact.

[0081] The first screen 1 includes the first screen inner side 1A and the first screen outer side 1B arranged oppositely, wherein the first screen inner side 1A refers to the display side of the first screen 1, and the first screen outer side 1B refers to the non-display side of the first screen 1. Similarly, the second screen 2 also includes the second screen inner side 2A and the second screen outer side 2B arranged oppositely. In the closed state of the electronic device 10 of the present application, the first screen inner side 1A and the second screen inner side 2A can be in contact (inner folding of the electronic device 10), or the first screen outer side 1B and the second screen outer side 2B can be in contact (outer folding of the electronic device 10).

[0082] FIG. 2 is a structural schematic diagram of the electronic device 10 in the closed state according to an embodiment of the present application. Please refer to FIG. 2, at this time, the electronic device 10 is in the closed state, that is, the distance between the first screen 1 and the second screen 2 is the closest.

[0083] The electronic device 10 will be described below taking the first screen inner side 1A and the second screen inner side 2A in contact as an example of the closed state of the electronic device 10.

[0084] Please refer to FIG. 3, the electronic device 10 further includes at least one set of magnetic components 4, the magnetic components 4 include the first magnetic component 41 and the second magnetic component 42 arranged oppositely, the first magnetic component 41 is arranged inside the first screen 1, and the second magnetic component 42 is arranged inside the second screen 2. When the first screen 1 and the second screen 2 are closed, the first magnetic component 41 and the second magnetic component 42 are attracted together. In the process of opening the first screen 1 and the second screen 2, the user needs to overcome the attraction force between the first screen 1 and the second screen 2 (the damping force between the first screen 1 and the second screen 2) to open the first screen 1 and the second screen 2.

[0085] In the process of closing the first screen 1 and the second screen 2 from the open state, the attraction force generated by the first magnetic component 41 and / or the second magnetic component 42 enables the first screen 1 and the second screen 2 to continuously attract each other in the closing process, and as the first screen 1 and the second screen 2 approach, the attraction force between the first screen 1 and the second screen 2 gradually increases, until the first screen 1 and the second screen 2 are closed.

[0086] In some embodiments, the first magnetic member 41 can be arranged at any region of the inner side 1A of the first screen, preferably, the first magnetic member 41 is arranged at the edge region of the inner side 1A of the first screen, so as to reduce the influence of the first magnetic member 41 on the display function of the first screen 1. Similarly, the second magnetic member 42 can be arranged at any region of the inner side 2A of the second screen, preferably, the second magnetic member 42 is arranged at the edge region of the inner side 2A of the second screen.

[0087] The magnetic force of the first magnetic member 41 can be adjusted, so as to adjust the magnetic force between the first screen 1 and the second screen 2. When the first screen 1 and the second screen 2 are open, the magnetic force of the first magnetic member 41 is adjusted, so that the magnetic properties of the first magnetic member 41 and the second magnetic member 42 are opposite, and the damping force between the first screen 1 and the second screen 2 is equal to the set damping force, so as to avoid the problem that the attraction force between the first screen 1 and the second screen 2 is too large, causing the user to have difficulty in opening the screen of the electronic device 10. When the first screen 1 and the second screen 2 are closed, the magnetic force between the first screen 1 and the second screen 2 is adjusted by adjusting the magnetic force of the first magnetic member 41, so that the magnetic properties of the first magnetic member 41 and the second magnetic member 42 are opposite, and the attraction force between the first screen 1 and the second screen 2 is equal to the set attraction force, so as to avoid the problem that the attraction force between the first screen 1 and the second screen 2 is too large, causing the first screen 1 and the second screen 2 to suddenly close.

[0088] The magnetic force of the second magnetic member 42 can be adjusted, so as to adjust the magnetic force between the first screen 1 and the second screen 2. When the first screen 1 and the second screen 2 are open, the magnetic force of the second magnetic member 42 is adjusted, so that the magnetic properties of the first magnetic member 41 and the second magnetic member 42 are opposite, and the damping force between the first screen 1 and the second screen 2 is equal to the set damping force, so as to avoid the problem that the attraction force between the first screen 1 and the second screen 2 is too large, causing the user to have difficulty in opening the screen of the electronic device 10. When the first screen 1 and the second screen 2 are closed, the magnetic force between the first screen 1 and the second screen 2 is adjusted by adjusting the magnetic force of the second magnetic member 42, so that the magnetic properties of the first magnetic member 41 and the second magnetic member 42 are opposite, and the attraction force between the first screen 1 and the second screen 2 is equal to the set attraction force, so as to avoid the problem that the attraction force between the first screen 1 and the second screen 2 is too large, causing the first screen 1 and the second screen 2 to suddenly close.

[0089] The setting attractive force and the setting damping force are both artificially set. The setting attractive force refers to an ideal value of the attractive force between the first screen 1 and the second screen 2 when the first screen 1 and the second screen 2 are closed, which is set by the user in advance, i.e. the user experiences a good feeling when closing the first screen 1 and the second screen 2 under the setting attractive force. The setting damping force refers to an ideal value of the damping force between the first screen 1 and the second screen 2 when the first screen 1 and the second screen 2 are opened, which is set by the user in advance, i.e. the user experiences a good feeling when opening the first screen 1 and the second screen 2 under the setting damping force. In some embodiments, the setting attractive force and the setting damping force are specific numerical values. In other embodiments, the setting attractive force and the setting damping force are both a range of values.

[0100] In the electronic device 10 of the present application, three groups, four groups or more groups of magnetic components 4 can also be provided, which is not limited in the present application, as long as at least one magnetic member with adjustable magnetic force is provided in each group of magnetic components 4.

[0101] Fig. 6 is a structure diagram of the first magnetic member 41 provided in an embodiment of the present application. As shown in Fig. 6, when the magnetic force generated by the first magnetic member 41 is fixed, the first magnetic member 41 includes at least one first magnet 411. The first magnetic member 41 can include one, two or more first magnets 411. The more the number of the first magnets 411, the greater the magnetic force generated by the first magnetic member 41. When the first magnetic member 41 includes two or more first magnets 411, the two or more first magnets 411 are arranged adjacently or stacked.

[0102] In some embodiments, the first magnet 411 comprises a permanent magnet. The permanent magnet may, for example, comprise an aluminum-nickel-cobalt permanent magnet alloy, an iron-chromium-cobalt permanent magnet alloy, a permanent ferrite, a rare earth permanent magnet material, and a composite permanent magnet material, etc. The specific material of the permanent magnet is not limited in the present application.

[0103] When the magnetic force generated by the first magnetic member 41 can be adjusted, the first magnetic member 41 further comprises a first winding 412. The first magnetic member 41 comprises the first magnet 411 and the first winding 412. The first winding 412 is arranged in the first screen 1 and is arranged on at least one side of the first magnet 411. The first winding 412 can adjust the magnetic force intensity of the first magnet 411 under the condition of being energized, thereby adjusting the magnetic force of the first magnetic member 41. According to the principle of an electromagnet, the first winding 412 is supplied with current, and the first winding 412 can generate an electromagnetic field. When the first winding 412 and the first magnet 411 are close to each other, the electromagnetic field and the magnetic field of the first magnet 411 will be superimposed, thereby changing the magnetic force intensity of the first magnetic member 41. According to the size, time, and direction of the current input to the first winding 412, the first magnet 411 generates magnetic forces of different sizes, i.e., the magnetic field of the first magnetic member 41 is adjusted.

[0104] In some embodiments, the number of the first magnet 411 arranged in the first magnetic member 41 is at least one, and the number of the first winding 412 arranged in the first magnetic member 41 is at least one. The number of the first magnet 411 and the number of the first winding 412 can be the same, or one first winding 412 can correspond to multiple first magnets 411. In FIG. 6, the structure schematic diagram of one first winding 412 corresponding to one first magnet 411 is shown.

It can be understood that the more the number of the first magnet in the first magnetic member 41, the greater the magnetic force intensity generated by the first magnetic member 41, and the wider the range of the adjustable magnetic force intensity of the first magnetic member 41.

[0106] The following is an example of controlling the direction of the magnetic field by changing the direction and magnitude of the current through the first winding 412, thereby enhancing the magnetic field of the first magnet 411 or weakening the magnetic field of the first magnet 411. For example, the initial magnetic field strength of the first magnet 411 is M0, and when the current I applied to the first winding 412 is 0A, the magnetic field strength of the first magnet 411 remains M0. When a reverse current is applied to the first winding 412, the electromagnetic field generated by the first winding 412 superimposes the magnetic field of the first magnet 411, causing the magnetic field strength of the first magnet 411 to increase, and the corresponding magnetic field strength M1 of the first magnet 411 is greater than M0. As the reverse current increases, the magnetic force strength generated by the first magnet 411 increases. When a positive current is applied to the first winding 412, the electromagnetic field generated by the first winding 412 superimposes the magnetic field of the first magnet 411, causing the magnetic field strength of the first magnet 411 to decrease, and the corresponding magnetic field strength M2 of the first magnet 411 is less than M0. As the positive current increases, the magnetic force strength generated by the first magnet 411 continues to decrease. In this application, the positive current refers to the direction of the current measured by the right-hand screw rule, and the direction of the reverse current is opposite to that of the positive current.

[0107] In this application, the first magnet 411 includes oppositely arranged upper and lower sides, and oppositely arranged left and right sides. The first winding 412 can be arranged on any side of the first magnet 411.

[0110] When the magnetic force generated by the second magnetic member 42 is fixed, the second magnetic member 42 includes at least one second magnet 421, and the second magnetic member 42 can include one, two or more second magnets 421. The more the number of second magnets 421, the greater the magnetic force strength of the second magnetic member 42. When the second magnetic member 42 includes two or more second magnets 421, the two or more second magnets 421 are arranged adjacently or stacked.

[0111] In some embodiments, the second magnet 421 comprises a permanent magnet.

[0133] FIG. 16 is a control schematic diagram of the electronic device 10 provided in the embodiments of the application. Referring to FIG. 16, the electronic device 10 further comprises a control module 101 and a triggering module 102, the triggering module 102 is connected with the control module 101, and the control module 101 is connected with at least one of the first winding 412 and the second winding 422. The triggering module 102 is used to determine whether the user needs to open the first screen 1 and the second screen 2. The control module 101 controls whether at least one of the first winding 412 and the second winding 422 is energized according to the determination result of the triggering module 102. When the triggering module 102 determines that the user needs to open the first screen 1 and the second screen 2, the control module 101 controls at least one of the first winding 412 and the second winding 422 to be energized, so as to adjust the damping force between the first screen 1 and the second screen 2, until the above-mentioned damping force is equal to the set damping force.

[0134] In some embodiments, the control module 101 can be a processor or a controller, for example, can be a Central Processing Unit (CPU), a general-purpose processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, a transistor logic device, a hardware component, or any combination thereof. It can implement or execute various exemplary logical blocks, modules and circuits described in connection with the present disclosure.

[0135] In some embodiments, the trigger signal of the trigger module 102 includes at least one of pressing, touching, playing audio, playing video and setting a motion state of the electronic device 10. The specific trigger module 102 can be various sensors installed on the electronic device 10. For example, the trigger module 102 can be a pressure sensor installed on a specific area of the electronic device 10, and the pressure sensor is connected with the controller. When the user wants to adjust the damping force between the first screen 1 and the second screen 2, the pressure sensor of the specific area is triggered by pressing or touching, and the control module 101 controls the magnetic force strength of at least one of the first magnetic member 41 and the second magnetic member 42 through the trigger signal transmitted by the pressure sensor, so that the damping force between the first screen 1 and the second screen 2 is equal to the set damping force, thereby completing the adjustment of the first screen 1 and the second screen 2. In other examples, the trigger module 102 can also be a microphone, a gyroscope, etc., which are not limited herein.

[0136] Taking the conversion of the first screen 1 and the second screen 2 from the closed state to the open state, and the user opening the first screen 1 as an example of opening, the attractive force between the first screen 1 and the second screen 2 is denoted as F1, the friction force of the folding axis 3 between the first screen 1 and the second screen 2 is denoted as F2, the rebound force between the first screen 1 and the second screen 2 is denoted as F3, and the gravity of the first screen 1 is denoted as G. In order to ensure the product cycle of the electronic device 10 and no gap when the first screen 1 and the second screen 2 are closed, the following conditions are met: min +F2 min -F3 max -G>0 (Ⅰ)

[0137] In formula (I), F1 min denotes the minimum value of the attractive force between the first screen 1 and the second screen 2, F2 min denotes the minimum value of the friction force of the folding axis 3 between the first screen 1 and the second screen 2, and F3max refers to the maximum value of the repulsive force between the first screen 1 and the second screen 2.

[0138] Generally, the user normally opens the first screen 1 without considering gravity, and the opening force F (i.e., the damping force between the first screen 1 and the second screen 2) when the user opens the first screen 1 and the second screen 2 is as follows: F = F1 + F2 - F3 (II)

[0139] However, during the assembly and use of the electronic device 10, the values of F1, F2 and F3 in formula (II) will fluctuate, and the value of F2 will continuously decay with repeated opening and closing of the first screen 1 and the second screen 2, resulting in a large fluctuation in the opening force F.

[0140] The application uses the control module 101 to control the size of the current of at least one of the first winding 412 and the second winding 422 by triggering the trigger module 102, dynamically adjusts the attractive force F1 between the first screen 1 and the second screen 2, so that the damping force F of the first screen 1 and the second screen 2 is appropriate when the first screen 1 and the second screen 2 are opened, and the user experience is improved.

[0141] In the process of just starting to close the first screen 1 and the second screen 2, the distance between the first screen 1 and the second screen 2 is far, and the first screen 1 and the second screen 2 are mainly adjusted by the folding shaft 3. As the angle between the first screen 1 and the second screen 2 decreases, the attractive force between the first screen 1 and the second screen 2 gradually increases, and further combined with the torque characteristics of the folding shaft 3 between the first screen 1 and the second screen 2, the first screen 1 and the second screen 2 may be closed in a large impact state.

[0142] FIG. 17 is another control schematic diagram of the electronic device 10 provided by the embodiment of the application. Referring to FIG. 17, for the above-mentioned case, the electronic device 10 provided by the embodiment of the application further includes an angle measuring device 103, the angle measuring device 103 is connected with the control module 101, and the angle measuring device 103 is used to measure the angle between the first screen 1 and the second screen 2 in real time in the closing process of the first screen 1 and the second screen 2. When the angle between the first screen 1 and the second screen 2 is less than or equal to a preset angle, the control module 101 controls at least one of the first winding 412 and the second winding 422 to be energized, adjusts the magnetic force intensity of at least one of the first magnetic member 41 and the second magnetic member 42, so that the attractive force between the first screen 1 and the second screen 2 is smaller and equal to the set attractive force, thereby avoiding the first screen 1 and the second screen 2 from being suddenly closed, and improving the user's use experience. In the application, the preset angle is a critical angle for the user to pre-set whether the magnetic force intensity of the first screen 1 and the second screen 2 needs to be adjusted.

[0143] The angle measuring device 103 can be a sensor carrying a certain functional module, which measures the included angle between the first screen 1 and the second screen 2 by means of light, magnetic field, distance, etc. The angle measuring device 103 can be, for example, a light sensor, a gyroscope sensor, a barometric pressure sensor, a magnetic sensor, a distance sensor, etc.

[0144] In some embodiments, the setting of the damping force and the setting of the attractive force of the present application can be preset by an application program in the electronic device 10. The preset included angle is usually preset during the design and assembly stage of the electronic device.

[0145] In some embodiments, the electronic device 10 further comprises a communication module for the communication of information or instructions inside the electronic device 10. The communication module can be a transceiver, a transceiver circuit or a communication interface, etc.

[0146] In some embodiments, the electronic device 10 can further comprise a storage module for storing the program code and data of the electronic device 10. The storage module can be, for example, a memory.

[0147] The present application also provides a screen opening force degree adjusting method based on the above electronic device, which is used to adjust the opening force degree of the first screen 1 and the second screen 2 in the opening process of the electronic device 10. FIG. 18 is a flow chart of the screen opening force degree adjusting method according to an embodiment of the present application. Referring to FIG. 18, the adjusting method comprises the following steps

[0148] S100, determining the setting damping force required by the user when opening the first screen 1 and the second screen 2.

[0149] Before determining the setting damping force required by the user when opening the first screen 1 and the second screen 2, it is necessary to set the damping force adjusting range between the first screen 1 and the second screen 2 when opening the first screen 1 and the second screen 2. During the assembly and design of the electronic device 10 of the present application, researchers pre-set the maximum value and the minimum value of the damping force between the first screen 1 and the second screen 2 in the user interface 100 through user experience, i.e. to determine the adjusting range of the damping force between the first screen 1 and the second screen 2.

[0150] S200, adjusting the magnetic force intensity of at least one of the first magnetic member 41 and the second magnetic member 42, so that the magnetic properties of the first magnetic member 41 and the second magnetic member 42 are opposite, and the real-time damping force between the first screen 1 and the second screen 2 is equal to the setting damping force.

[0151] In this step, the size of the damping force between the first screen 1 and the second screen 2 is equal to the set damping force. It can be understood that the value of the damping force between the first screen 1 and the second screen 2 is equal to the value of the set damping force, or the real-time damping force between the first screen 1 and the second screen 2 is within the range of the set damping force.

[0152] In this step, the electronic device 10 is triggered to energize at least one of the first winding 412 and the second winding 422, and adjust at least one of the current size, the current direction, and the energization time to make the magnetic properties of the first magnetic member 41 and the second magnetic member 42 opposite, and the size of the damping force between the first screen 1 and the second screen 2 equal to the set damping force. In the actual adjustment process, whether the electronic device 10 is triggered is generally determined by comparing the size of the damping force between the first screen 1 and the second screen 2 when not energized and the set damping force.

Moreover, different users can adjust the size of the set damping force according to their own experience, and then adjust the real-time damping force of the first screen 1 and the second screen 2, which can realize customization for different users and greatly improve the user experience.

[0164] The present application also provides a screen closing force adjustment method based on the above-mentioned electronic device, which is used to adjust the closing force of the first screen 1 and the second screen 2 in the closing process of the electronic device 10. FIG. 21 is a flow chart of the screen closing force adjustment method provided by the present application, please refer to FIG. 21, which includes the following steps:

[0165] A100, determining the set attractive force required when the user closes the first screen 1 and the second screen 2.

[0166] Before step A100, the adjustment range of the attractive force between the first screen 1 and the second screen 2 when the first screen 1 and the second screen 2 are closed needs to be set. During the assembly design of the electronic device 10 of the present application, researchers pre-set the maximum value and the minimum value of the attractive force between the first screen 1 and the second screen 2 in the user interface 100 through user experience, i.e., determine the adjustment range of the attractive force between the first screen 1 and the second screen 2.

[0167] Before step A100, a preset angle at which the magnetic force needs to be adjusted when the first screen 1 and the second screen 2 are closed is also needed to be set. In the process that the first screen 1 and the second screen 2 are just starting to close, the distance between the first screen 1 and the second screen 2 is far, and the first screen 1 and the second screen 2 are mainly adjusted by the folding shaft 3; with the decrease of the angle between the first screen 1 and the second screen 2, the attractive force between the first screen 1 and the second screen 2 gradually increases, and further combining the torque characteristics of the folding shaft 3 between the first screen 1 and the second screen 2 causes the first screen 1 and the second screen 2 to be closed in a larger impact state. In this application, the angle of the preset angle can be set in the electronic device 10 in advance according to the experience of the person skilled in the art, so as to avoid the first screen 1 and the second screen 2 being closed in a larger impact state.

[0168] A200, adjust the magnetic force strength of at least one of the first magnetic member 41 and the second magnetic member 42, so that the magnetism of the first magnetic member 41 and the second magnetic member 42 is opposite, and the size of the real-time attractive force between the first screen 1 and the second screen 2 is equal to the set attractive force.

[0169] In this step, adjusting the magnetic force strength of at least one of the first magnetic member 41 and the second magnetic member 42 includes: obtaining the real-time angle between the first screen 1 and the second screen 2 in the process of closing the first screen 1 and the second screen 2; when the real-time angle is less than or equal to the preset angle, the electronic device 10 energizes at least one of the first magnetic member 41 and the second magnetic member 42, and adjusts at least one of the current size, the current direction and the energizing time of at least one of the first magnetic member 41 and the second magnetic member 42 under the energizing condition. When the first screen 1 and the second screen 2 are closed, the angle between the first screen 1 and the second screen 2 can be measured in real time by the angle measuring device 103 arranged inside the electronic device 10, and whether to energize at least one of the first magnetic member 41 and the second magnetic member 42 is determined by comparing the size of the preset angle and the real-time measured angle. When the real-time angle is greater than the preset angle, the first magnetic member 41 and the second magnetic member 42 do not need to be adjusted; when the real-time angle is less than or equal to the preset angle, the electronic device 10 energizes at least one of the first magnetic member 41 and the second magnetic member 42, and adjusts the current size, the current direction and the duration of the energizing according to the difference between the attractive force corresponding to the angle and the set attractive force, until the attractive force between the first screen 1 and the second screen 2 is equal to the set attractive force, or the real-time attractive force is within the range of the set attractive force.

[0170] The application controls the included angle between the first screen 1 and the second screen 2 to be less than or equal to the preset included angle, and then energizes at least one of the first magnetic member 41 and the second magnetic member 42, so that the energization can be accurately performed, the timeliness and effectiveness are improved, the waste of resources caused by the constant connection of the power supply with the first magnetic member 41 and the second magnetic member 42 is avoided, and the power consumption of the electronic device is reduced.

[0174] A102, control at least one of the first magnetic member 41 and the second magnetic member 42 in communication with the electronic device 10 through the second adjustment component 400 to generate a magnetic field with a corresponding attraction force strength.

[0175] Specifically, the user experiences closing the first screen 1 and the second screen 2 for at least once, and adjusts the size of the real-time attraction force between the first screen 1 and the second screen 2 in the second adjustment component 400 according to each experience.

[0176] A103, obtain the real-time attraction force between the first screen 1 and the second screen 2 corresponding to the good experience of the user interface 100, and determine the set attraction force according to the real-time attraction force.

[0177] Specifically, the user clicks the second confirmation button 500, and the real-time attraction force between the first screen 1 and the second screen 2 displayed by the user interface 100 at this time is the set attraction force.

[0178] In this step, the attraction force between the first screen 1 and the second screen 2 corresponding to the good experience of the user can be a certain value, and can also be several values. When the attraction force between the first screen 1 and the second screen 2 corresponding to the good experience is a certain value, the set attraction force is a specific value. When the attraction force between the first screen 1 and the second screen 2 corresponding to the good experience is several values, i.e., the user can confirm whether to click the second determination button according to each self-experience, the confirmation of the good experience can click the second confirmation button 500 at least once. At this time, the set attraction force is a range value composed of the above several values.

When the user wants to adjust the first screen 1 and the second screen 2, the electronic device 10 energizes at least one of the first winding 412 and the second winding 422, so that F0 is equal to F1, and the adjustment of the magnetic force between the first screen 1 and the second screen 2 is completed.

[0181] The present application can quickly adjust the magnetic force strength between the first screen 1 and the second screen 2 according to the user's needs by pre-determining the set attraction corresponding to the user closing the first screen 1 and the second screen 2 to the preset angle, and can avoid frequently adjusting the magnetic force strength when the first screen 1 and the second screen 2 are closed according to the same user's usage habits, thereby improving the adjustment efficiency and bringing great convenience to the user.
