[0001] This application belongs to the field of electronic equipment technology, specifically relating to an electronic device and a method for controlling the opening and closing of the electronic device. Background Technology

[0002] With the continuous development of screen technology, the screens of electronic devices are becoming larger and larger to provide users with richer information and a better user experience. However, the excessive size of the screens can seriously affect the portability of electronic devices. Therefore, in recent years, electronic devices with foldable screens have become a new development direction. Foldable screen electronic devices not only have the display effect of a large screen, but also improve portability and storage through folding.

[0003] In related technologies, magnets are placed at the edges of foldable screen electronic devices to achieve the folding action of the screen. During the unfolding process, the opening angle of the electronic device is manually adjusted. However, the magnetic closure method and manual adjustment of the opening angle in these technologies cannot achieve precise control over the opening angle and are inconvenient for users to operate with one hand. Summary of the Invention

[0004] This application aims to provide an electronic device and an opening and closing control method for the electronic device, in order to solve the problems in the related technologies of magnetic attraction and manual adjustment of the opening and closing angle, which cannot achieve precise control of the opening and closing angle and are inconvenient for users to operate with one hand.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide an electronic device, including: a first body, a second body, a first electromagnetic component, a second electromagnetic component, and a driving module;

[0007] A pivot is provided between the first body and the second body, and at least one of the first body and the second body can rotate around the pivot to switch the electronic device between a folded state and an unfolded state.

[0008] The first electromagnetic component is disposed on the first body, and the second electromagnetic component is disposed on the second body. The first electromagnetic component includes a plurality of first electromagnetic elements, and the second electromagnetic component includes a plurality of second electromagnetic elements. The plurality of first electromagnetic elements and the plurality of second electromagnetic elements are distributed along an axis perpendicular to the rotation axis.

[0009] When the electronic device is in the folded state, each of the first electromagnetic components corresponds to one of the second electromagnetic components, and each of the first electromagnetic components and the corresponding second electromagnetic component forms an electromagnetic group.

[0010] The drive module is electrically connected to the plurality of electromagnetic groups respectively. The drive module is used to control the magnitude and direction of the current of the electromagnetic groups at different positions to adjust the opening and closing angle between the first body and the second body.

[0011] Secondly, embodiments of this application propose an opening and closing control method for an electronic device, applied to the aforementioned electronic device, the method comprising:

[0012] Receives user's opening and closing operation commands;

[0013] In response to the opening and closing operation command, the target opening and closing angle between the first body and the second body is obtained;

[0014] The first and second electromagnetic components in the control electromagnetic assembly are energized.

[0015] Adjust the magnitude and direction of the current in the electromagnetic group at different positions to adjust the opening and closing angle between the first body and the second body to the target opening and closing angle.

[0016] In embodiments of this application, the electronic device includes a first body and a second body, with a pivot between them.

The first body has a first electromagnetic component, and the second body has a second electromagnetic component. The first electromagnetic component includes multiple first electromagnetic elements, and the second electromagnetic component includes multiple second electromagnetic elements. Both the multiple first and second electromagnetic elements are distributed along an axis perpendicular to the pivot. When the electronic device is in the folded state, each first electromagnetic element corresponds to one second electromagnetic element, and each first electromagnetic element and its corresponding second electromagnetic element form an electromagnetic group. A drive module is electrically connected to each of the electromagnetic groups. By changing the positions of the energized first and second electromagnetic elements and adjusting the magnitude and direction of the current in the first and second electromagnetic elements, the magnetic force between the first and second electromagnetic components can be adjusted. This allows for adjustment of the opening angle between the first and second bodies, enabling precise control and adjustment of the opening angle, facilitating one-handed operation and improving the user experience.

[0034] The following description, in conjunction with the accompanying drawings, details an electronic device and an electronic device opening / closing control method provided in this application through specific embodiments and application scenarios.

[0035] like Figure 1 and Figure 4As shown, an electronic device according to some embodiments of this application includes: a first body 10, a second body 20, a first electromagnetic component 101, a second electromagnetic component 201, and a drive module 40; a pivot 30 is provided between the first body 10 and the second body 20, and at least one of the first body 10 and the second body 20 can rotate around the pivot 30 to switch the electronic device between a folded state and an unfolded state. The first electromagnetic component 101 is disposed on the first body 10, and the second electromagnetic component 201 is disposed on the second body 20. The first electromagnetic component 101 includes a plurality of first electromagnetic elements 1011, and the second electromagnetic component 201 includes a plurality of second electromagnetic elements 2011. The plurality of first electromagnetic elements 1011 and the plurality of second electromagnetic elements 2011 are all distributed along an axis perpendicular to the pivot 30. When the electronic device is in a folded state, each first electromagnetic element 1011 corresponds to a second electromagnetic element 2011, and each first electromagnetic element 1011 and its corresponding second electromagnetic element 2011 form an electromagnetic group 100; the drive module 40 is electrically connected to the multiple electromagnetic groups 100 respectively, and the drive module 40 is used to control the magnitude and direction of the current of the electromagnetic groups 100 at different positions to adjust the opening angle A between the first body 10 and the second body 20.

[0036] In this embodiment of the application, the first body 10 and the second body 20 can be connected around the pivot 30 to allow the electronic device to switch between a folded state and an unfolded state. The first body 10 is provided with a first electromagnetic component 101, and the second body 20 is provided with a second electromagnetic component 201. The first electromagnetic component 101 includes a plurality of first electromagnetic elements 1011, and the second electromagnetic component 201 includes a plurality of second electromagnetic elements 2011. The plurality of first electromagnetic elements 1011 and the plurality of second electromagnetic elements 2011 are distributed along an axis perpendicular to the pivot 30. When the electronic device is in a folded state, each first electromagnetic component 1011 corresponds to a second electromagnetic component 2011, and each first electromagnetic component 1011 and its corresponding second electromagnetic component 2011 form an electromagnetic group 100. A drive module 40 is electrically connected to multiple electromagnetic groups 100. By changing the position of the energized first electromagnetic component 1011 and second electromagnetic component 2011, and adjusting the magnitude and direction of the current in the first electromagnetic component 1011 and second electromagnetic component 2011, the magnetic force between the first electromagnetic component 101 and the second electromagnetic component 201 can be adjusted. This allows for adjustment of the opening angle A between the first body 10 and the second body 20, thereby achieving precise control and adjustment of the opening angle A, facilitating one-handed opening and closing operation, and improving the user experience.

[0037] Specifically, the electronic device includes a first body 10 and a second body 20, which are connected by a pivot 30. At least one of the first body 10 and the second body 20 is rotatably connected to the pivot 30 and can rotate around the pivot 30 to achieve relative opening and closing between the first body 10 and the second body 20, thereby switching the electronic device between a folded state and an unfolded state. When the electronic device is in the folded state, the opening angle A between the first body 10 and the second body 20 is close to 0°; when the electronic device is in the unfolded state, the opening angle A between the first body 10 and the second body 20 is close to 180°.

[0038] The electronic devices in this application embodiment may include any one of the following: smartphones, tablets, e-readers, in-vehicle computers, navigators, digital cameras, smart TVs, and wearable devices. Of course, the electronic devices may also be other types of foldable electronic devices, and this application embodiment does not limit them.

[0039] Furthermore, a first electromagnetic component 101 is provided on the first body 10, and a second electromagnetic component 201 is provided on the second body 20. When the electronic device is in a folded state, the first electromagnetic component 101 and the second electromagnetic component 201 are positioned opposite each other, so that when the first electromagnetic component 101 and the second electromagnetic component 201 are powered on, a repulsive force or an attractive force can be generated between them. In turn, the relative movement between the first electromagnetic component 101 and the second electromagnetic component 201 drives the relative movement of the first body 10 and the second body 20.

[0040] Specifically, such as Figures 1 to 4 As shown, the first electromagnetic component 101 includes a plurality of first electromagnetic elements 1011, and the second electromagnetic component 201 includes a plurality of second electromagnetic elements 2011. On the first body 10, the plurality of first electromagnetic elements 1011 are distributed along an axial direction perpendicular to the rotation shaft 30, and adjacent first electromagnetic elements 1011 are insulated from each other. On the second body 20, the plurality of second electromagnetic elements 2011 are distributed along an axial direction perpendicular to the rotation shaft 30, and adjacent second electromagnetic elements 2011 are insulated from each other.

[0041] Specifically, such as Figure 4 As shown, the number of first electromagnetic elements 1011 on the first body 10 can be set to be the same as the number of second electromagnetic elements 2011 on the second body 20. Furthermore, when the electronic device is in a folded state, each first electromagnetic element 1011 on the first body 10 corresponds to one second electromagnetic element 2011 on the second body 20. Thus, each first electromagnetic element 1011 and its corresponding second electromagnetic element 2011 can form an electromagnetic group 100, and multiple electromagnetic groups 100 can be formed by multiple first electromagnetic elements 1011 and multiple second electromagnetic elements 2011.

[0042] A drive module 40 is set in the electronic device. By electrically connecting the drive module 40 to multiple electromagnetic groups 100 respectively, the drive module 40 can control the energization of electromagnetic groups 100 at different positions and adjust the magnitude and direction of the current of electromagnetic groups 100. The magnitude and direction of the magnetic force between the first electromagnetic component 101 and the second electromagnetic component 201 can be adjusted to change the magnetic force between the first electromagnetic component 101 and the second electromagnetic component 201, thereby achieving precise control and adjustment of the opening angle A between the first body 10 and the second body 20.

[0043] It is understood that each electromagnetic assembly 100 includes a first electromagnetic element 1011 and a second electromagnetic element 2011 arranged opposite to each other. When energized, the first electromagnetic element 1011 and the second electromagnetic element 2011 will generate a magnetic force. By changing the current direction of the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic assembly 100, a magnetic attraction force or repulsion force can be generated between the first electromagnetic element 1011 and the second electromagnetic element 2011. Under the action of the magnetic force, the first electromagnetic element 1011 and the second electromagnetic element 2011 can move closer or further away from each other, so as to drive the first body 10 and the second body 20 to open or close relative to each other.

[0044] Furthermore, along the axial direction perpendicular to the rotating shaft 30, the distance between different electromagnetic groups 100 and the rotating shaft is different. By controlling the energization of electromagnetic groups 100 at different positions, the torque between the first body 10 and the second body 20 can be changed, thereby enabling the first body 10 and the second body 20 to continuously open and close.

[0045] In a specific application, during the unfolding process of the first body 10 and the second body 20 from the folded state, the drive module 40 controls the first electromagnetic component 1011 and the second electromagnetic component 2011 to be energized, and controls the direction of the current so that the end of the first electromagnetic component 1011 facing the second electromagnetic component 2011 generates the same magnetic pole as the end of the second electromagnetic component 201 facing the first electromagnetic component 101, thereby forming a repulsive force between the first electromagnetic component 1011 and the second electromagnetic component 2011, thereby driving the first body 10 and the second body 20 to unfold relative to each other.

[0046] Accordingly, during the closing process of the first body 10 and the second body 20 from the unfolded state, the drive module 40 can be used to control the first electromagnetic component 101 and the second electromagnetic component 201 to be energized, and control the direction of the current to make the end of the first electromagnetic component 101 facing the second electromagnetic component 201 generate opposite magnetic poles to the end of the second electromagnetic component 201 facing the first electromagnetic component 101, thereby forming an attractive force between the first electromagnetic component 101 and the second electromagnetic component 201, thereby driving the first body 10 and the second body 20 to close relative to each other.

[0047] Furthermore, the magnitude of the current flowing through the first electromagnetic component 101 and the second electromagnetic component 201 can be adjusted by module control to regulate the magnitude of the repulsive or attractive force between the first electromagnetic component 101 and the second electromagnetic component 201, thereby adjusting the relative moving speed of the first body 10 and the second body 20, and achieving precise control of the opening and closing process of the electronic device.

[0048] In some embodiments, the adjustable range of the opening angle A is 0° to 90°, where the opening angle A refers to the angle between the plane containing the first body 10 and the plane containing the second body 20. In this embodiment, when the opening angle A is 0°, the first body 10 and the second body 20 are relatively closed; when the opening angle A is 90°, the torque between the first electromagnetic component 101 and the second electromagnetic component 201 is zero. Optionally, the opening angle A may include any angle such as 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°.

[0049] In this embodiment, precise control and adjustment of the opening angle A can enhance the user experience and expand the application scenarios of the electronic device. For example, when a user watches a video on one side of the foldable screen electronic device, the opening angle A can be adjusted to 45°, thereby using the body of the electronic device as a stand and improving ease of use.

[0050] Optionally, in a direction perpendicular to the axis of rotation 30, a plurality of first electromagnetic components 1011 are evenly spaced in the first body 10, and a plurality of second electromagnetic components 2011 are evenly spaced in the second body 20.

[0051] In this embodiment, a plurality of first electromagnetic elements 1011 on the first body 10 are evenly spaced along an axis perpendicular to the rotating shaft 30, and a plurality of second electromagnetic elements 2011 on the second body 20 are evenly spaced along an axis perpendicular to the rotating shaft 30, with each first electromagnetic element 1011 corresponding to one second electromagnetic element 2011. This facilitates uniform torque control between the first body 10 and the second body 20 during the relative opening and closing of the electronic device by sequentially controlling the energization of electromagnetic groups 100 at different positions, ensuring relatively uniform movement between them and enabling precise control of the opening and closing speed of the electronic device.

[0052] It should be noted that the number of first electromagnetic elements 1011 on the first body 10 and the spacing between two adjacent first electromagnetic elements 1011, as well as the number of second electromagnetic elements 2011 on the second body 20 and the spacing between two adjacent second electromagnetic elements 2011, can be set according to the structure and size of the first body 10 and the second body 20. This application embodiment does not limit this.

[0053] Optionally, such as Figure 3 As shown, a first insulating spacer 1012 is provided between two adjacent first electromagnetic components 1011, and a second insulating spacer 2012 is provided between two adjacent second electromagnetic components 2011. In this embodiment, by providing the first insulating spacer 1012, insulation is achieved between two adjacent first electromagnetic components 1011, and by providing the second insulating spacer 2012, insulation is achieved between two adjacent second electromagnetic components 2011, thereby avoiding mutual interference between two adjacent second electromagnetic components 2011 and between two adjacent second electromagnetic components 2011 when energized.

[0054] Specifically, when the drive module 40 controls the energization of multiple first electromagnetic components 1011 and multiple second electromagnetic components 2011, the current direction in two adjacent first electromagnetic components 1011 is the same, and the current direction in two adjacent second electromagnetic components 2011 is the same. However, the current direction in the first electromagnetic component 1011 and the second electromagnetic component 2011 can be the same or opposite, and the specific current direction is controlled according to the unfolding or closing requirements of the actual electronic device.

[0055] It should be noted that the first insulating spacer 1012 and the second insulating spacer 2012 can be made of insulating materials, such as insulating rubber, insulating plastic, insulating ceramics, etc. Of course, other insulating materials can also be used. Those skilled in the art can make selections according to actual needs, and the embodiments of this application do not limit this.

[0056] Optionally, such as Figure 2 As shown, the drive module 40 includes a drive circuit 401, a first switching switch 402 and a second switching switch 403. The drive circuit 401 is connected to a plurality of first electromagnetic components 1011 through the first switching switch 402, and the drive circuit 401 is connected to a plurality of second electromagnetic components 2011 through the second switching switch 403.

[0057] In this embodiment of the application, by setting a drive circuit 401, a first switching switch 402, and a second switching switch 403, the drive circuit 401 can control different first electromagnetic components 1011 to be energized or de-energized respectively through the first switching switch 402, and the drive circuit 401 can also control different second electromagnetic components 2011 to be energized or de-energized respectively through the second switching switch 403. Thus, the drive circuit 401 can individually control the energization status of electromagnetic groups 100 at different positions, thereby achieving precise control of the opening and closing process of the electronic device.

[0058] A first switch 402 can be provided in the electronic device. The drive circuit 401 is connected to each first electromagnetic component 1011 through the first switch 402. The first switch 402 can be used to control the connection or disconnection between each first electromagnetic component 1011 and the drive circuit 401. Similarly, a second switch 403 can be provided in the electronic device. The drive circuit 401 is connected to each second electromagnetic component 2011 through the second switch 403. The second switch 403 can be used to control the connection or disconnection between each second electromagnetic component 2011 and the drive circuit 401.

[0059] Specifically, such as Figure 2 As shown, during the folding process of the electronic device, the drive circuit 401 simultaneously supplies current to the first electromagnetic component 1011 and the second electromagnetic component 2011 in the electromagnetic assembly 100, so that an attraction is generated between the first electromagnetic component 1011 and the second electromagnetic component 2011. By sequentially changing the position and number of the electromagnetic assemblies 100 connected to the drive circuit 401 through the first switching switch 402 and the second switching switch 403, the magnitude of the attraction between the first electromagnetic component 101 and the second electromagnetic component 201 is changed, causing the first body 10 and the second body 20 to move toward each other, thereby controlling the closing process of the electronic device.

[0060] During the deployment of the electronic device, the drive circuit 401 simultaneously supplies current to the first electromagnetic component 1011 and the second electromagnetic component 2011 in the electromagnetic assembly 100, thereby generating a repulsive force between the first electromagnetic component 1011 and the second electromagnetic component 2011. By sequentially changing the position and number of electromagnetic assemblies 100 connected to the drive circuit 401 through the first switching switch 402 and the second switching switch 403, the magnitude of the repulsive force between the first electromagnetic component 101 and the second electromagnetic component 201 is changed, causing the first body 10 and the second body 20 to move in a direction away from each other, thus controlling the deployment process of the electronic device.

[0061] Furthermore, the magnitude of the current flowing through the first electromagnetic component 1011 and the second electromagnetic component 2011 can be changed by the drive circuit 401 to adjust the torque between the first body 10 and the second body 20, thereby adjusting the opening and closing speed between the first body 10 and the second body 20 and achieving precise control of the opening and closing process.

[0062] Optionally, such as Figure 1 As shown, there are two sets of first electromagnetic components 101, symmetrically arranged at both ends of the first body 10 along a first direction. Correspondingly, there are two sets of second electromagnetic components 201, symmetrically arranged at both ends of the second body 20, wherein the first direction is the axial direction parallel to the rotation shaft 30. When the electronic device is in a folded state, one first electromagnetic component 101 and one second electromagnetic component 201 are positioned opposite each other.

[0063] In this embodiment, first electromagnetic components 101 can be respectively provided at both ends of the first body 10, and correspondingly, second electromagnetic components 201 can be respectively provided at both ends of the second body 20, so that each first electromagnetic component 101 corresponds to one second electromagnetic component 201. Through the cooperation of the two first electromagnetic components 101 and the two second electromagnetic components 201, during the relative opening and closing process of the first body 10 and the second body 20, the two ends of the first body 10 and the second body 20 can be evenly stressed, so as to avoid local stress and cause local deformation of the first body 10 and the second body 20, thereby playing a protective role for the first body 10 and the second body 20.

[0064] Specifically, along an axis parallel to the rotating shaft 30, first electromagnetic components 101 can be respectively arranged at both ends of the first body 10 near the edge, and correspondingly, second electromagnetic components 201 can be respectively arranged at both ends of the second body 20 near the edge. When the electronic device is in a folded state, the positions of one first electromagnetic component 101 and one second electromagnetic component 201 correspond. The two first electromagnetic components 101 and the two second electromagnetic components 201 are respectively connected to the drive module 40. During the adjustment of the opening angle A, the drive module 40 synchronously controls the two first electromagnetic components 101 and the two second electromagnetic components 201 to be energized.

[0065] It is understood that the electronic device also includes a display screen 60. During the opening and closing process, if the first body 10 and the second body 20 are subjected to localized force, they will undergo localized torsional deformation, which can easily lead to damage to the display screen 60. In this embodiment, by providing a first electromagnetic component 101 at both ends of the first body 10 and a second electromagnetic component 201 at both ends of the second body 20, the ends of the first body 10 and the second body 20 can be subjected to force simultaneously, making the overall force on the first body 10 and the second body 20 more uniform, thereby reducing the damage to the display screen 60 caused by localized deformation of the first body 10 and the second body 20.

[0066] In some embodiments, such as Figure 4 and Figure 5 As shown, taking an example where there are 16 first electromagnetic components 1011 and 16 second electromagnetic components 2011, the 16 first electromagnetic components 1011 on the first body 10 and the 16 second electromagnetic components 2011 on the second body 20 correspond one-to-one and form 16 electromagnetic groups 100. The 16 electromagnetic groups 100 are arranged sequentially from the end away from the rotating shaft 30 to the end closer to the rotating shaft 30. The electromagnetic group 100 at the end away from the rotating shaft 30 is numbered 1, and the electromagnetic group 100 at the end closer to the rotating shaft 30 is numbered 16.

[0067] When the first body 10 and the second body 20 begin to open from their closed state, the drive module 40 can control the energization of electromagnetic groups 1-4 100, thereby creating a repulsive force between the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic group 100, which pushes the first body 10 and the second body 20 to unfold relative to each other. When the opening angle A reaches 2°, the energization of electromagnetic groups 2-5 100 is controlled, and so on. As the opening angle A between the first body 10 and the second body 20 increases, the position of the energized electromagnetic groups 100 is successively moved towards the direction closer to the rotating shaft 30, so as to adjust the opening angle A between the first body 10 and the second body 20 to the target opening angle, achieving precise control of the opening angle A. The correspondence between the opening angle A and the position of the electromagnetic group 100 can be predetermined, so that the drive module 40 controls the corresponding electromagnetic group 100 to be energized according to the preset correspondence and the actual opening angle A.

[0068] Among them, such as Figure 4 As shown, the maximum distance H0 between the energized electromagnetic groups 100 can be controlled to always remain within a preset spacing range, thereby generating a stable repulsive force between the electromagnetic groups 100, so that the first body 10 and the second body 20 can be opened relatively stably.

[0069] Furthermore, the number of energized electromagnetic groups 100 can be increased or decreased according to the opening and closing speed of the first body 10 and the second body 20, so as to adjust the opening and closing speed. For example, as the opening and closing angle A increases, the magnetic torque will decrease. Using the same number of electromagnetic groups 100 to energize, the opening and closing speed will slow down. Therefore, the opening and closing speed can be increased by increasing the number of energized electromagnetic groups 100.

[0070] Of course, when the first body 10 and the second body 20 begin to close from the unfolded state, the corresponding electromagnetic group 100 can also be energized by the drive module 40, so that the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic group 100 form an attraction force, thereby achieving a relatively stable closure of the first body 10 and the second body 20, so as to adjust the opening angle A between the first body 10 and the second body 20 to the target opening angle. The specific control process can be referred to the aforementioned unfolding process settings, which will not be repeated here in the embodiments of this application.

[0071] It should be noted that the specific number and location of the first electromagnetic component 1011 and the second electromagnetic component 2011, as well as the power supply control method of the drive module 40 to the electromagnetic group 100 during the actual opening and closing process, can be determined according to actual needs, and no restrictions are imposed on them in this embodiment.

[0072] Optionally, such as Figure 1 As shown, the electronic device also includes: an angle detection module 50; the angle detection module 50 is disposed in the first body 10 or the second body 20, and the angle detection module 50 is used to detect the included angle between the first body 10 and the second body 20; the drive module 40 is electrically connected to the angle detection module 50, and the drive module 40 is used to adjust the current of the first electromagnetic component 1011 or the second electromagnetic component 2011 according to the included angle between the first body 10 and the second body 20.

[0073] In this embodiment, an angle detection module 50 is provided in the electronic device. The angle detection module 50 is disposed in the first body 10 or the second body 20. The angle detection module 50 is electrically connected to the drive module 40. The angle detection module 50 can detect the angle between the first body 10 and the second body 20 in real time. Then, the drive module 40 can adjust the current of the first electromagnetic component 1011 or the second electromagnetic component 2011 according to the angle detected by the angle detection module 50 in real time, so as to change the magnetic force between the first electromagnetic component 1011 and the second electromagnetic component 2011, thereby changing the angle between the first body 10 and the second body 20, and realizing precise adjustment of the opening and closing angle A.

[0074] In some embodiments, the angle detection module 50 may include a Hall angle sensor, a photoelectric angle sensor, a rotation angle sensor, etc., which may be connected to at least one of the first body 10, the second body 20, or the rotating shaft 30.

[0075] Optionally, such as Figure 1 As shown, the angle detection module 50 includes: a first inertial measurement unit 501 and a second inertial measurement unit 502; the first inertial measurement unit 501 is disposed on the first body 10, and the second inertial measurement unit 502 is disposed on the second body 20; during the opening and closing process of the first body 10 and the second body 20, the first inertial measurement unit 501 and the second inertial measurement unit 502 are adapted to detect the included angle and the opening and closing speed between the first body 10 and the second body 20; the drive module 40 is electrically connected to the first inertial measurement unit 501 and the second inertial measurement unit 502 respectively, and the drive module 40 is used to provide current to the first electromagnetic component 1011 and the second electromagnetic component 2011 in the electromagnetic group 100 at different positions according to the included angle and the opening and closing speed, and to adjust the magnitude and direction of the current of the first electromagnetic component 1011 and the second electromagnetic component 2011.

[0076] In this embodiment, a first inertial measurement unit 501 is provided on the first body 10, and a second inertial measurement unit 502 is provided on the second body 20. During the opening and closing process of the electronic device, the angle between the first inertial measurement unit 501 and the second inertial measurement unit 502 can be detected through the mutual induction between them. This facilitates the drive module 40 to control the electromagnetic group 100 at different positions to be energized based on the angle and opening and closing speed detected in real time, and to control the energization of the electromagnetic group 100, so as to achieve precise control of the opening and closing process of the electronic device.

[0077] Specifically, the angle detection module 50 can employ an inertial measurement unit (IMU), such as... Figure 1 As shown, IMUs are respectively installed on the first body 10 and the second body 20. By utilizing the mutual sensing between the two IMUs, the angle between the first body 10 and the second body 20 and the opening and closing speed can be detected in real time.

[0078] The drive module 40 is electrically connected to two IMUs respectively. During the opening and closing process of the electronic device, the IMU can detect the included angle and opening and closing speed in real time, and transmit the detected included angle and opening and closing speed signals to the drive module 40. The drive module 40 controls the electromagnetic group 100 at different positions to be energized according to the received included angle and real-time opening and closing speed, and adjusts the current magnitude and direction of the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic group 100, so as to adjust the opening and closing angle A and the opening and closing speed.

[0079] In some embodiments, depending on the application scenario of the electronic device, for example, when the electronic device is dropped or bumped, the IMU can be used to identify changes in acceleration, and then the drive module 40 can control the current direction and magnitude of the first electromagnetic component 1011 and the second electromagnetic component 2011, so that the first electromagnetic component 1011 and the second electromagnetic component 2011 generate a larger attraction force, so that the first body 10 and the second body 20 are more tightly fastened, thereby preventing the electronic device from unfolding from the folded state when it is dropped, and causing secondary damage to the internal flexible folding screen.

[0080] Optionally, the electronic device also includes a display screen 60, which is disposed on one side of the first body 10 and the second body 20. The first electromagnetic component 1011 and the second electromagnetic component 2011 are both electromagnetic steel sheets, which are attached to the display screen 60.

[0081] Specifically, such as Figure 3 As shown, the electromagnetic steel sheet may include a steel sheet and a wire. The wire is arranged around the steel sheet. By passing a current through the wire, the steel sheet can generate a magnetic field, thereby causing the electromagnetic steel sheet to produce an electromagnetic effect. Using the electromagnetic steel sheet as the first electromagnetic component 1011 and the second electromagnetic component 2011 results in a simple structure, small space occupation, which is beneficial to the overall layout of the electronic device, and has low manufacturing cost.

[0082] Optionally, such as Figure 1 and Figure 6 As shown, a first permanent magnet 102 is provided at one end of the first body 10 away from the pivot 30, and a second permanent magnet 202 is provided at one end of the second body 20 away from the pivot 30. When the electronic device is in a folded state, the first permanent magnet 102 and the second permanent magnet 202 attract each other.

[0083] In this embodiment of the application, a first permanent magnet 102 is provided on the first body 10 and a second permanent magnet 202 is provided on the second body 20. The first permanent magnet 102 and the second permanent magnet 202 attract each other, so that when the electronic device is in a folded state, the magnetic attraction between the first permanent magnet 102 and the second permanent magnet 202 keeps the electronic device locked, thereby de-energizing the first electromagnetic component 101 and the second electromagnetic component 201 to reduce power consumption.

[0084] Specifically, a first permanent magnet 102 can be provided at one end of the first body 10 away from the pivot 30, and a second permanent magnet 202 can be provided at one end of the second body 20 away from the pivot 30. When the electronic device is in a folded state, the magnetic poles of the ends of the first permanent magnet 102 and the second permanent magnet 202 that are close to each other are the same, thereby forming a continuous attractive force between them. The first permanent magnet 102 and the second permanent magnet 202 can be permanent magnets.

[0085] like Figure 6 As shown, the end of the first permanent magnet 102 facing the second permanent magnet 202 can be set as the S pole, and the end of the second permanent magnet 202 facing the first permanent magnet 102 can be set as the N pole. Then, an adsorption force is formed between the first permanent magnet 102 and the second permanent magnet 202. When it is necessary to control the first body 10 and the second body 10 to unfold relative to each other, the first electromagnetic component 101 and the first electromagnetic component 201 are energized to form a repulsive force between the first electromagnetic component 101 and the first electromagnetic component 201, and the generated repulsive force is greater than the adsorption force, so that the first body 10 and the second body 10 can unfold relative to each other.

[0086] It is understandable that, such as Figure 7 The diagram illustrates parameter changes during the opening and closing process of the electronic device according to an embodiment of this application. As the opening angle A between the first body 10 and the second body 10 gradually increases, the attraction force between the first permanent magnet 102 and the second permanent magnet 202 gradually decreases. When the opening angle A reaches a certain angle, the attraction force between the first permanent magnet 102 and the second permanent magnet 202 decreases to a negligible level. With the number of electromagnetic groups 100 remaining constant, as the position of the electromagnetic groups 100 moves towards the rotation axis, the total magnetic torque decreases due to the continuously decreasing lever arm. Correspondingly, the magnetic torque can be increased by increasing the number of electromagnetic groups 100.

[0087] Reference Figure 8 This application also provides an electronic device opening and closing control method, applied to the electronic device in the above embodiments. The specific method may include the following steps:

[0088] Step 101: Receive the user's opening and closing operation command.

[0089] In this embodiment of the application, the user can determine the target opening and closing angle between the first body 10 and the second body 20 as needed, and trigger an automatic opening and closing operation command. The opening and closing operation command includes the target opening and closing angle input by the user, and the server receives the user's opening and closing operation command.

[0090] Step 102: In response to the opening and closing operation command, obtain the target opening and closing angle between the first body 10 and the second body 20.

[0091] In this embodiment of the application, the server receives the user's opening and closing operation command and obtains the user's preset target opening and closing angle according to the opening and closing operation command.

[0092] Step 103: Power on the first electromagnetic component 1011 and the second electromagnetic component 2011 in the electromagnetic assembly 100.

[0093] In this embodiment of the application, the server control drive circuit 401 provides current to the first electromagnetic component 1011 and the second electromagnetic component 2011. Furthermore, the first electromagnetic component 1011 at different positions can be energized or de-energized by the first switching switch 402, and the second electromagnetic component 2011 at different positions can be energized or de-energized by the second switching switch 403.

[0094] Specifically, each first electromagnetic element 1011 on the first body 10 corresponds to a second electromagnetic element 2011 on the second body 20, and one first electromagnetic element 1011 and its corresponding second electromagnetic element 2011 can form an electromagnetic group 100. Multiple electromagnetic elements 1011 and multiple second electromagnetic elements 2011 can form multiple electromagnetic groups 100. The server control drive circuit 401 supplies power to different electromagnetic groups 100. When the drive circuit 401 supplies current to each electromagnetic group 100, it simultaneously supplies power to the first electromagnetic element 1011 and the second electromagnetic element 2011 in that electromagnetic group 100.

[0095] Step 104: Adjust the magnitude and direction of the current in the electromagnetic group 100 at different positions to adjust the opening angle A between the first body 10 and the second body 20 to the target opening angle.

[0096] In this embodiment, a controller energizes different electromagnetic groups 100, adjusting the current direction of the first electromagnetic element 1011 and the second electromagnetic element 2011 within the electromagnetic group 100. This creates an attractive or repulsive force between the first electromagnetic element 1011 and the second electromagnetic element 2011, causing the first body 10 and the second body 20 to close or open relative to each other. By adjusting the current magnitude of the first electromagnetic element 1011 and the second electromagnetic element 2011 within the electromagnetic group 100, the magnetic force between them can be changed, thereby adjusting the relative movement speed between the first body 10 and the second body 20. This allows for precise adjustment of the opening angle A between the first body 10 and the second body 20, bringing the opening angle A to a user-preset target opening angle.

[0097] In this embodiment, the electronic device includes a first body 10 and a second body 20. A pivot 30 is provided between the first body 10 and the second body 20. At least one of the first body 10 and the second body 20 can rotate around the pivot 30 to switch the electronic device between a folded state and an unfolded state. A first electromagnetic component 101 is provided on the first body 10, and a second electromagnetic component 201 is provided on the second body 20. The first electromagnetic component 101 includes a plurality of first electromagnetic elements 1011, and the second electromagnetic component 201 includes a plurality of second electromagnetic elements 2011. The plurality of first electromagnetic elements 1011 and the plurality of second electromagnetic elements 2011 are distributed along an axis perpendicular to the pivot 30. When the electronic device is in a folded state, each first electromagnetic component 1011 corresponds to a second electromagnetic component 2011, and each first electromagnetic component 1011 and its corresponding second electromagnetic component 2011 form an electromagnetic group 100. The drive module 40 is electrically connected to multiple electromagnetic groups 100 respectively. By changing the position of the energized first electromagnetic component 1011 and second electromagnetic component 2011, and adjusting the magnitude and direction of the current in the first electromagnetic component 1011 and the second electromagnetic component 2011, the magnetic force between the first electromagnetic component 101 and the second electromagnetic component 201 can be adjusted. This allows for adjustment of the opening angle A between the first body 10 and the second body 20, thereby enabling precise control and adjustment of the opening angle A, facilitating one-handed opening and closing operation and improving the user experience.

[0098] Reference Figure 9 This application also provides another method for controlling the opening and closing of an electronic device, which may specifically include the following steps:

[0099] Step 201: Receive the user's opening and closing operation command.

[0100] Specifically, the implementation process of this step can be referred to step 101, and will not be elaborated here.

[0101] Step 202: In response to the opening and closing operation command, obtain the target opening and closing angle between the first body 10 and the second body 20.

[0102] Specifically, the implementation process of this step can be referred to step 102, and will not be elaborated here.

[0103] Step 203: Power on the first electromagnetic component 1011 and the second electromagnetic component 2011 in the electromagnetic assembly 100.

[0104] Specifically, the implementation process of this step can be referred to step 103, and will not be elaborated here.

[0105] Step 204: Obtain the opening and closing speeds of the first body 10 and the second body 20, and determine the magnitudes of the opening and closing speeds relative to a first preset value and a second preset value, wherein the second preset value is greater than the first preset value.

[0106] In this embodiment, the user can predetermine a preset range of opening and closing speeds according to actual needs. This preset range includes an upper limit and a lower limit, with the upper limit serving as the first preset value and the lower limit as the second preset value. For example, the preset range of opening and closing speeds can be set to 15° / s to 20° / s, meaning the first preset value is 15° / s and the second preset value is 20° / s. The user's opening and closing operation command includes both the first and second preset values, and the server can obtain these values ​​based on the user's command.

[0107] After the first electromagnetic component 1011 and the second electromagnetic component 2011 in each electromagnetic group 100 are energized, an initial force is obtained between the first body 10 and the second body 20, and the first body 10 and the second body 20 move relative to each other. The relative opening and closing speed between the first body 10 and the second body 20 is obtained, and the obtained opening and closing speed is compared with the first preset value and the second preset value.

[0108] Specifically, an angular velocity detection module can be installed in the electronic device to detect the real-time opening and closing speeds of the first body 10 and the second body 20 during relative motion. The angular velocity detection module may include an inertial measurement unit (IMU). IMUs are installed on both the first body 10 and the second body 20. By utilizing the mutual sensing between the two IMUs, real-time detection of the angle between the first body 10 and the second body 20 and the opening and closing speeds can be achieved.

[0109] Step 205: When the opening and closing speed is less than or equal to the first preset value, add one electromagnetic group 100 to be energized; when the opening and closing speed is greater than or equal to the second preset value, reduce one electromagnetic group 100 from being energized.

[0110] In this embodiment of the application, the opening and closing speed is compared with a first preset value. When the opening and closing speed is less than or equal to the first preset value, an electromagnetic group 100 is energized to increase the relative opening and closing speed of the first body 10 and the second body 20.

[0111] The system continuously monitors and acquires the opening and closing speeds of the first body 10 and the second body 20, and determines the magnitude of the opening and closing speeds relative to a first preset value. Specifically, when the opening and closing speeds are less than or equal to the first preset value, an additional electromagnetic group 100 is energized to increase the relative opening and closing speeds of the first body 10 and the second body 20; when the opening and closing speeds are greater than the first preset value, the system determines the magnitude of the opening and closing speeds relative to a second preset value.

[0112] In this embodiment of the application, the opening and closing speed is determined to be greater than or equal to the second preset value. When the opening and closing speed is greater than or equal to the second preset value, the energization of one electromagnetic group 100 is reduced to decrease the relative opening and closing speed of the first body 10 and the second body 20. When the opening and closing speed is less than the second preset value, step 204 is continued.

[0113] Step 206: Adjust the magnitude and direction of the current in the energized electromagnetic assembly 100 to adjust the opening angle between the first body 10 and the second body 20 to the target opening angle.

[0114] In this embodiment, by adjusting the current direction of the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic assembly 100, an attractive or repulsive force is formed between the first electromagnetic element 1011 and the second electromagnetic element 2011, thereby causing the first body 10 and the second body 20 to be relatively closed or opened. Furthermore, by adjusting the magnitude of the current in the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic assembly 100, the relative movement speed between the first body 10 and the second body 20 can be adjusted. This allows for precise adjustment of the opening angle A between the first body 10 and the second body 20, adjusting A to a user-preset target opening angle.

[0115] Optionally, the step 205 of adding an electromagnetic group 100 to be energized includes:

[0116] During the unfolding of the electronic device, energized electromagnetic groups 100 are added sequentially along a first direction, which is a direction perpendicular to the axis of rotation 30 from away from rotation 30 to close to rotation 30.

[0117] During the closing process of the electronic device, energized electromagnetic groups 100 are added sequentially along the second direction, which is opposite to the first direction.

[0118] Specifically, an electronic device may be provided with multiple electromagnetic groups 100. Each electromagnetic group 100 includes a first electromagnetic element 1011 and a second electromagnetic element 2011 arranged in opposite positions. By passing current through the first electromagnetic element 1011 and the second electromagnetic element 2011 in the electromagnetic group 100, an attractive or repulsive force can be generated between the first electromagnetic element 1011 and the second electromagnetic element 2011.

[0119] During the transition of the electronic device from a folded state to an unfolded state, one or more electromagnetic groups 100 at the end furthest from the pivot 30 can be designated as the initial energized electromagnetic group. The first electromagnetic element 1011 and the second electromagnetic element 2011 in the initial energized electromagnetic group are energized to generate an initial repulsive force between the first body 10 and the second body 20. When additional energized electromagnetic groups 100 are required, they are sequentially added along the first direction, starting from the end of the initial energized electromagnetic group closest to the pivot 30.

[0120] During the transition of the electronic device from an unfolded state to a folded state, one or more electromagnetic groups 100 near the pivot 30 can be designated as the initial energized electromagnetic group. The first electromagnetic element 1011 and the second electromagnetic element 2011 in the initial energized electromagnetic group are energized to create an initial attraction between the first body 10 and the second body 20. When additional energized electromagnetic groups 100 are required, they are sequentially added along the second direction from the end of the initial energized electromagnetic group furthest from the pivot 30.

[0121] It should be noted that the number of electromagnetic groups 100 included in the initial energized electromagnetic group can be set according to actual needs, and this application embodiment does not limit this.

[0122] Optionally, reducing the energization of one electromagnetic group 100 in step 205 includes:

[0123] During the unfolding of the electronic device, the number of energized electromagnetic groups 100 is reduced sequentially along a first direction, the first direction being a direction perpendicular to the axis of rotation 30 from away from rotation 30 to close to rotation 30.

[0124] During the closing process of the electronic device, the number of energized electromagnetic groups 100 is reduced sequentially along the second direction, which is opposite to the first direction.

[0125] Specifically, during the switching process of the electronic device from a folded state to an unfolded state, one or more electromagnetic groups 100 at the end furthest from the pivot 30 can be set as the initial energized electromagnetic group. The first electromagnetic element 1011 and the second electromagnetic element 2011 in the initial energized electromagnetic group are energized to generate an initial repulsive force between the first body 10 and the second body 20. When it is necessary to reduce the number of energized electromagnetic groups 100, the energized electromagnetic groups 100 are sequentially reduced along the first direction from the end of the initial energized electromagnetic group furthest from the pivot 30.

[0126] During the transition of the electronic device from an unfolded state to a folded state, one or more electromagnetic groups 100 near the pivot 30 can be designated as the initial energized electromagnetic group. The first electromagnetic element 1011 and the second electromagnetic element 2011 in the initial energized electromagnetic group are energized to create an initial attraction between the first body 10 and the second body 20. When it is necessary to reduce the number of energized electromagnetic groups 100, the energized electromagnetic groups 100 are sequentially reduced from the end of the initial energized electromagnetic group near the pivot 30 along the second direction.

[0127] In the embodiments of this application, such as Figure 5 As shown, taking an example where there are 16 first electromagnetic components 1011 and 16 second electromagnetic components 2011, the 16 first electromagnetic components 1011 on the first body 10 and the 16 second electromagnetic components 2011 on the second body 20 correspond one-to-one, forming 16 electromagnetic groups 100. The 16 electromagnetic groups 100 are arranged sequentially from the end away from the rotating shaft 30 to the end closer to the rotating shaft 30. The electromagnetic group 100 at the end away from the rotating shaft 30 is numbered 1, and the electromagnetic group 100 at the end closer to the rotating shaft 30 is numbered 16. The preset range of the opening and closing speed is 15° / s to 20° / s, that is, the first preset value is 15° / s, and the second preset value is 20° / s.

[0128] During the relative unfolding process of the first body 10 and the second body 20, electromagnetic groups 1 to 4 are pre-set as the initial energized electromagnetic groups. After the user triggers the opening and closing operation command, the controller controls electromagnetic groups 1 to 4 to be energized. The relative opening and closing speed of the first body 10 and the second body 20 is detected and compared with a first preset value and a second preset value. If the opening and closing speed is less than or equal to 15° / s, electromagnetic group 5 is energized; if the opening and closing speed is greater than or equal to 20° / s, electromagnetic group 100 is de-energized, i.e., electromagnetic group 100 is de-energized.

[0129] Accordingly, during the relative closing process of the first body 10 and the second body 20, electromagnetic groups 13 to 16 are preset as the initial energized electromagnetic groups. After the user triggers the opening and closing operation command, the controller controls electromagnetic groups 13 to 16 to be energized. The relative opening and closing speed of the first body 10 and the second body 20 is detected and compared with the magnitude of the opening and closing speed and the first preset value and the second preset value. If the opening and closing speed is less than or equal to 15° / s, the controller controls the energization of electromagnetic group 12 to be increased; if the opening and closing speed is greater than or equal to 20° / s, the controller controls the energization of electromagnetic group 16 to be decreased, that is, the energization of electromagnetic group 16 to be de-energized.

[0130] It is understandable that during the relative unfolding of the first body 10 and the second body 20, the electromagnetic group 100 generates a repulsive force after being energized, while during the relative closing of the first body 10 and the second body 20, the electromagnetic group 100 generates an attractive force after being energized.

[0131] In this embodiment, by acquiring the opening and closing speeds of the first body 10 and the second body 20, the magnitude of the opening and closing speed relative to a first preset value and a second preset value is determined. When the opening and closing speed is less than or equal to the first preset value, an additional electromagnetic group 100 is energized; when the opening and closing speed is greater than or equal to the second preset value, one electromagnetic group is de-energized. Furthermore, by adjusting the magnitude and direction of the current in the first electromagnetic component 1011 and the second electromagnetic component 2011, the opening and closing angle between the first body and the second body is adjusted to the target opening and closing angle. This allows for precise control of the opening and closing speed and angle of the first body 10 and the second body 20 according to the user's wishes, improving the user experience.
