Description

Technical Field

[0001] The present application belongs to the technical field of electronic products, and specifically relates to electronic equipment. Background Art

[0002] Competition in the mobile terminal industry is increasingly trending towards large screens and ultra-thin devices, but large screens make the entire device too large and inconvenient to carry. Foldable electronic devices can solve the above problem by changing the size of the electronic device due to their folding function, and are now popular with a large number of users. Currently, the left and right shells are usually controlled to rotate relative to the folding device to achieve unfolding and folding, but after folding, the unfolding and tight fit of the two shells cannot be effectively controlled. Summary of the invention

[0003] In view of this, the present application provides an electronic device, which includes a first shell, a second shell, a first magnetic module, and a second magnetic module, the first magnetic module is arranged on the first shell, and the second magnetic module is arranged on the second shell; when the electronic device changes from an unfolded state to a folded state, the first shell and the second shell are close to each other, the first magnetic module and the second magnetic module are magnetically attracted to each other, so that the first shell is connected to the second shell; when the electronic device is to change from the folded state to the unfolded state, the first magnetic module and the second magnetic module can magnetically repel each other, so that the first shell and the second shell are separated.

[0004] The electronic device provided by the present application is configured such that a first magnetic module is arranged in a first shell and a second magnetic module is arranged in a second shell, and the first magnetic module and the second magnetic module can cooperate with each other. Specifically, when the electronic device changes from an unfolded state to a folded state, the first shell and the second shell are close to each other during rotation, and at this time, the first magnetic module and the second magnetic module are also close to each other. The present application can make the first magnetic module and the second magnetic module magnetically attracted to each other, that is, the face-to-face magnetic poles of the first magnetic module and the second magnetic module are opposite, one magnetic module is the N pole, and the other magnetic module is the S pole. When the first magnetic module and the second magnetic module are close to a certain extent, the first shell can be connected to the second shell by magnetic attraction, so that the first shell and the second shell can fit tightly together.

[0005] When the electronic device wants to be unfolded from the folding device, before unfolding, the present application can first make the first magnetic module and the second magnetic module magnetically repel each other, that is, the first magnetic module and the second magnetic module face to face with the same magnetic pole, for example, both magnetic modules are N poles, or both magnetic modules are S poles. Through the repulsive force between the first magnetic module and the second magnetic module, the first shell and the second shell can be separated from each other and no longer tightly fitted together. This makes it easier for the user to hold the first shell and the second shell to put the electronic device in the unfolded state.

[0006] In summary, compared with the related art in which the first shell and the second shell are connected by snaps, the present application can change the control mode of the electronic device by cooperating with the first magnetic module and the second magnetic module, which is simple to operate and improves the experience of unfolding the electronic device. In addition, no components are set on the surface of the electronic device, which can improve the appearance performance of the electronic device. In addition, the present application only needs to control the magnetism of the first magnetic module and the second magnetic module to change the unfolding mode of the electronic device, and can easily and quickly realize the unfolding and tight fit of the first shell and the second shell.

DETAILED DESCRIPTION

[0022] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0023] Before introducing the technical solution of the present application, the technical problems in the related technology are introduced in detail.

[0024] With the market demand for the "display area" of terminal products such as mobile phones and tablets, the competition in the mobile terminal industry is increasingly tending towards large screens and ultra-thinness. However, large screens make the size of the whole machine too large and inconvenient to carry. The smart phone industry is ushering in an experience revolution brought about by form innovation. The display form of mobile phone products has developed from the initial hard screen to flexible screen, from small screen to large screen and full screen, from static mechanism to motion mechanism. Recently, major mobile phone manufacturers have been developing folding screens, sliding screens, etc., striving to expand the form and display boundaries of mobile phone products, so that they have the functions of mobile phones, tablets and even computers. As an electronic device with a new display form, foldable electronic devices can be unfolded or closed due to their folding function, and have a larger display area when unfolded, and a smaller overall size when folded, which can solve the above problems. It is now loved by the majority of users.

[0025] A foldable electronic device generally includes two housings and a folding device connected to the two housings. The folding device can realize the unfolding and folding of the left and right housings, thereby realizing the unfolding and folding functions of the electronic device. When the electronic device is in a folded state, additional components are required to connect and fit the two housings together to improve the connection reliability of the electronic device. Otherwise, the unfolding and tight fitting of the two housings cannot be effectively controlled after folding.

[0026] The existing commonly used buckle structure connected with the button is implemented. For example, the button and the buckle structure are provided in one housing, and the other housing is provided with a slot. When the electronic device is in a folded state, the buckle is engaged in the slot to connect the two housings together. When the electronic device is to be unfolded, the button can be used to separate the buckle from the slot, and then the user can unfold the two housings. However, the above method is complicated to operate, and the buckle and the slot will protrude from the surface of the electronic device, which reduces the appearance performance.

[0027] Some people also set magnets in the two shells, and the polarities of the two magnets are opposite. When the electronic device is folded, the magnetic attraction of the two magnets sticks together. But when unfolding, it needs to be operated by both hands, which is troublesome to operate and difficult to control the strength. Moreover, the shells of foldable electronic devices are usually thin, and the gap between the two shells is small, so it is difficult to hold the two shells with both hands, and the operation and unfolding experience is not good.

[0028] In view of this, in order to solve the above problems, this application provides an electronic device, please refer to Figure 1-Figure 4 , Figure 1 This is a schematic diagram of an electronic device in an unfolded state according to an embodiment of the present application. Figure 2 for Figure 1 A front view of the electronic device is shown. Figure 3 for Figure 1 A front view of the electronic device is shown in a folded state. Figure 4 for Figure 3 The front view of the electronic device shown is when it is about to be unfolded. The electronic device 1 provided in this embodiment includes a first shell 11, a second shell 12, a first magnetic module 21, and a second magnetic module 22, wherein the first magnetic module 21 is arranged on the first shell 11, and the second magnetic module 22 is arranged on the second shell 12. When the electronic device 1 is moved from the unfolded state to the folded state, the first shell 11 and the second shell 12 are close to each other, and the first magnetic module 21 and the second magnetic module 22 are magnetically attracted to each other, so that the first shell 11 is connected to the second shell 12. When the electronic device 1 is about to move from the folded state to the unfolded state, the first magnetic module 21 and the second magnetic module 22 can magnetically repel each other, so that the first shell 11 and the second shell 12 are separated.

[0029] The electronic device 1 provided in this embodiment includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc. This embodiment does not limit the type of electronic device 1, and only uses mobile phones for schematic illustration.

[0030] It is worth noting that the electronic device 1 provided in this embodiment is not a conventional electronic device 1, but a bendable and foldable electronic device 1. In this case, the electronic device 1 can also be referred to as a foldable electronic device 1. Specifically, the electronic device 1 includes two shells: a first shell 11 and a second shell 12. The components of the electronic device 1 can be respectively arranged in the first shell 11 and the second shell 12. The electronic device 1 has an unfolded state and a folded state. The unfolded state can be understood as the state when the first shell 11 and the second shell 12 are flattened. The first shell 11 and the second shell 12 are arranged horizontally in a direction perpendicular to their thickness. In this case, the first shell 11 can also be referred to as the right shell, and the second shell 12 can also be referred to as the left shell. The folded state can be understood as the state when the first shell 11 and the second shell 12 are folded. The first shell 11 and the second shell 12 are arranged in a direction parallel to their thickness, that is, the first shell 11 and the second shell 12 are each rotated approximately 90° in a direction close to each other, so as to be arranged vertically. As for the shape, structure, material and other parameters of the first shell 11 and the second shell 12, this embodiment does not limit them here. Optionally, the first shell 11 and the second shell 12 can be unfolded and folded through a folding device 30. One end of the folding device 30 is connected to the first shell 11, and the other end is connected to the second shell 12. The folding device 30 can move inside, thereby driving the first shell 11 and the second shell 12 to rotate relative to the folding device 30, thereby realizing the unfolding process and the folding process.

[0031] The electronic device 1 may also include two magnetic modules: a first magnetic module 21 and a second magnetic module 22. Each magnetic module is mainly composed of a magnet, so each magnetic module has magnetism. As for the specific magnetism of each magnetic module, this embodiment does not limit it here. The first magnetic module 21 can be set in the first shell 11. The first magnetic module 21 is mainly installed in the first shell 11. As for the installation position, this embodiment does not limit it. For example, the first magnetic module 21 can be set outside the first shell 11, and the first magnetic module 21 can also be set inside the first shell 11. This embodiment only schematically illustrates that the first magnetic module 21 is set in the first shell 11, and how the first magnetic module 21 is set in the first shell 11 is not limited in this embodiment.

[0032] Similarly, the second magnetic module 22 can be disposed in the second housing 12. The second magnetic module 22 is mainly installed in the second housing 12. As for the installation position, this embodiment does not limit it. For example, the second magnetic module 22 can be disposed outside the second housing 12, or the second magnetic module 22 can also be disposed inside the second housing 12. This embodiment only schematically illustrates that the second magnetic module 22 is disposed inside the second housing 12, and this embodiment does not limit how the second magnetic module 22 is disposed in the second housing 12.

[0033] The first magnetic module 21 and the second magnetic module 22 are not two independent modules. The first magnetic module 21 and the second magnetic module 22 can cooperate with each other magnetically, and the specific circumstances of the cooperation between the first magnetic module 21 and the second magnetic module 22 are different in different situations. Specifically, when the electronic device 1 changes from the unfolded state to the folded state, the first shell 11 and the second shell 12 approach each other during the rotation process, and at this time, the first magnetic module 21 and the second magnetic module 22 will also approach each other. This embodiment can make the first magnetic module 21 and the second magnetic module 22 magnetically attract each other, that is, the magnetic poles of the first magnetic module 21 and the second magnetic module 22 facing each other are opposite, for example, one magnetic module is the N pole and the other magnetic module is the S pole. This embodiment is only schematically illustrated with the first magnetic module 21 as the N pole and the second magnetic module 22 as the S pole. When the first magnetic module 21 and the second magnetic module 22 are brought close to each other to a certain extent, the first shell 11 can be connected to the second shell 12 by magnetic attraction, so that the first shell 11 and the second shell 12 are tightly fitted together.

[0034] When the electronic device 1 wants to move from the folding device 30 to the unfolded state, before unfolding, the present embodiment can first make the first magnetic module 21 and the second magnetic module 22 magnetically repel each other, that is, the first magnetic module 21 and the second magnetic module 22 face to face with the same magnetic pole, for example, both magnetic modules are N poles, or both magnetic modules are S poles. The present embodiment is only schematically illustrated with the first magnetic module 21 and the second magnetic module 22 being both S poles. Through the repulsive force between the first magnetic module 21 and the second magnetic module 22, the first shell 11 and the second shell 12 can be separated from each other and no longer tightly fitted together. At this time, the electronic device 1 has not been fully unfolded, and there is only a certain distance between the two shells. Thus, the user can place a finger in the gap between the first shell 11 and the second shell 12, so as to facilitate holding the first shell 11 and the second shell 12 and rotating them in the opposite direction, thereby putting the electronic device 1 in the unfolded state.

[0035] In summary, compared with the related art in which the first shell 11 and the second shell 12 are connected by snaps, this embodiment can change the control mode of the electronic device 1 by cooperating with the first magnetic module 21 and the second magnetic module 22, which is simple to operate and improves the experience of unfolding the electronic device 1. In addition, no components are set on the surface of the electronic device 1, which can improve the appearance performance of the electronic device 1. In addition, compared with the related art in which the magnetic attraction of a magnet is used to connect the two shells together, but they need to be pried apart by hand when unfolding, this embodiment only needs to control the magnetism of the first magnetic module 21 and the second magnetic module 22, which can change the unfolding mode of the electronic device 1, and can conveniently and quickly realize the unfolding and tight fit of the first shell 11 and the second shell 12.

[0036] Please refer to Figure 1 and Figure 5 , Figure 5 It is a schematic diagram of an electronic device in another embodiment of the present application when it is in an unfolded state. In this embodiment, the first magnetic module 21 includes at least one first magnetic member 210, and the second magnetic module 22 includes at least one second magnetic member 220. The first magnetic module 21 and the second magnetic module 22 satisfy one of the following conditions: when the first magnetic module 21 includes one first magnetic member 210, and the second magnetic module 22 includes one second magnetic member 220, the first magnetic member 210 and the second magnetic member 220 are both extended and arranged along a direction perpendicular to the arrangement direction of the first shell 11 and the second shell 12. Alternatively, when the first magnetic module 21 includes a plurality of the first magnetic members 210, and the second magnetic module 22 includes a plurality of the second magnetic members 220, each of the first magnetic members 210 is arranged in correspondence with one of the second magnetic members 220.

[0037] The two magnetic modules may also have various embodiments in terms of quantity and position. When the first magnetic module 21 includes a first magnetic member 210, the first magnetic member 210 may be extended along a direction perpendicular to the arrangement of the first shell 11 and the second shell 12. In other words, the first magnetic member 210 may be extended along the width direction of the electronic device 1, and the first magnetic member 210 is in the shape of a long strip. By extending the first magnetic member 210, the length of the first magnetic member 210 may be increased, thereby facilitating the cooperation with the second magnetic module 22.

[0038] Similarly, when the second magnetic module 22 includes a second magnetic member 220, the second magnetic member 220 is extended in a direction perpendicular to the second housing 12 and the arrangement direction of the second housing 12. In other words, the second magnetic member 220 can be extended in the width direction of the electronic device 1, and the second magnetic member 220 is in the shape of a long strip. By extending the second magnetic member 220, the length of the second magnetic member 220 can be increased, so that it is easy to match with the first magnetic module 21. This embodiment is only schematically described by extending a first magnetic member 210 and a second magnetic member 220 in the width direction of the electronic device 1.

[0039] Optionally, when the first magnetic module 21 includes a first magnetic member 210 and the second magnetic module 22 includes a second magnetic member 220, a first magnetic member 210 and a second magnetic member 220 may be arranged in a corresponding manner or slightly staggered. A slightly staggered arrangement may allow the first magnetic member 210 and the second magnetic member 220 to be magnetically matched, and the first magnetic member 210 and the second magnetic member 220 being arranged in a corresponding manner may further improve the effect of magnetic matching. This embodiment is only schematically described with the first magnetic member 210 and the second magnetic member 220 being arranged in a corresponding manner.

[0040] In another embodiment, the first magnetic module 21 may include a plurality of first magnetic members 210, and the second magnetic module 22 may include a plurality of second magnetic members 220, and the number of the first magnetic members 210 and the number of the second magnetic members 220 are the same, for example, the number of the first magnetic members 210 and the number of the second magnetic members 220 are both two. In this embodiment, each first magnetic member 210 can be arranged in correspondence with a second magnetic member 220, for example, two first magnetic members 210 are arranged at opposite ends of the first shell 11 along the arrangement direction perpendicular to the first shell 11 and the second shell 12, and two second magnetic members 220 are arranged at opposite ends of the second shell 12 along the arrangement direction perpendicular to the first shell 11 and the second shell 12, and one first magnetic member 210 corresponds to one second magnetic member 220, and another first magnetic member 210 corresponds to another second magnetic member 220, so that each group of magnetic members has the best magnetic matching effect, and the matching effect of the first magnetic module 21 and the second magnetic module 22 is improved. The above content can also be understood as that each of the four corners of the electronic device 1 is provided with a magnetic member, and the polarities of the two magnetic members in the same housing are the same, and the polarities of the magnetic members in different housings are opposite.

[0041] From the above content, it can be seen that the focus of this application is that the electronic device 1 can enable the first magnetic module 21 and the second magnetic module 22 to have different magnetic matching shapes under different circumstances. As for how to specifically implement the above-mentioned solution, this application provides a variety of specific implementation methods, which will be introduced in detail one by one below.

[0042] In this embodiment, when the electronic device 1 is to be moved from the folded state to the unfolded state, the first magnetic module 21 is flipped at a preset angle so that the first magnetic module 21 and the second magnetic module 22 are magnetically repelled from each other.

[0043] In this embodiment, the magnets in the first magnetic module 21 and the magnets in the second magnetic module 22 are permanent magnets, that is, the magnetic field generated by the permanent magnetic material inside the magnets, once magnetized, can maintain constant magnetism and is not affected by current. For this type of magnetic module, it usually has two magnetic poles arranged opposite to each other, for example, one end is an N pole and the other end is an S pole. When the first magnetic module 21 is arranged in the first shell 11, the two magnetic poles of the first magnetic module 21 can be arranged along the thickness direction of the first shell 11, that is, the upper end of the first magnetic module 21 is an N pole or an S pole, and the lower end is an S pole or an N pole. Similarly, when the second magnetic module 22 is arranged in the second shell 12, the two magnetic poles of the second magnetic module 22 can be arranged along the thickness direction of the second shell 12, that is, the upper end of the second magnetic module 22 is an N pole or an S pole, and the lower end is an S pole or an N pole.

[0044] When the electronic device 1 changes from the unfolded state to the folded state, the upper end of the first magnetic module 21 and the upper end of the second magnetic module 22 are close to each other, or the lower end of the first magnetic module 21 and the lower end of the second magnetic module 22 are close to each other. For example, the electronic device 1 is usually further provided with a flexible screen, which is provided on the first shell 11 and the second shell 12, and the upper end of the magnetic module is closer to the flexible screen than the lower end.

[0045] The existence of the flexible screen allows the electronic device 1 to be divided into inward folding and outward folding when folded, wherein inward folding refers to bringing the two ends of the flexible screen close to each other and facing each other. When the electronic device 1 is in the inward folding state, the two ends of the flexible screen can be close to each other or even abut against each other, and at the same time be hidden by the first shell 11 and the second shell 12. The user cannot see the flexible screen from the appearance, which can effectively protect the flexible screen. Outward folding refers to the bottom surface of the first shell 11 and the bottom surface of the second shell 12 being close to each other and facing each other. When the electronic device 1 is in the outward folding state, the bottom surface of the first shell 11 and the bottom surface of the second shell 12 can be close to each other or even abut against each other. At this time, the flexible screen is exposed, allowing the user to view the display even in the outward folding state.

[0046] When the electronic device 1 is in the inward folding state, the upper magnetic pole of the first magnetic module 21 cooperates with the upper magnetic pole of the second magnetic module 22, and vice versa when the electronic device 1 is in the outward folding state, the lower magnetic pole of the first magnetic module 21 cooperates with the lower magnetic pole of the second magnetic module 22. However, no matter which situation is the same for this embodiment, so this embodiment and the following only schematically illustrate the inward folding state when the electronic device 1 is in the folded state. In this embodiment, the magnetic pole at the upper end of the first magnetic module 21 and the magnetic pole at the upper end of the second magnetic module 22 can be opposite in polarity, for example, the magnetic pole at the upper end of the first magnetic module 21 is the N pole, and the magnetic pole at the upper end of the second magnetic module 22 is the S pole, or the magnetic pole at the upper end of the first magnetic module 21 is the S pole, and the magnetic pole at the upper end of the second magnetic module 22 is the N pole. In this way, when the electronic device 1 is in the folded state, the first magnetic module 21 and the second magnetic module 22 are magnetically attracted to each other, so that the first shell 11 can be tightly connected to the second shell 12.

[0047] When the electronic device 1 is to be changed from a folded state to an unfolded state, that is, when the electronic device 1 wants to be unfolded but has not yet been unfolded, the present embodiment can flip the first magnetic module 21 by a preset angle, so that the magnetic pole of the original lower end of the first magnetic module 21 is set upward, for example, the magnetic pole of the upper end of the first magnetic module 21 is the N pole, and the magnetic pole of the upper end of the second magnetic module 22 is the S pole. After the first magnetic module 21 is flipped by a preset angle, the S pole of the lower end is set upward. Since the magnetic pole of the upper end of the flipped first magnetic module 21 is the same as the magnetic pole of the upper end of the second magnetic module 22, both are S poles, the two have the same magnetism and will repel each other, thereby separating the first shell 11 and the second shell 12 that were originally tightly fitted together by a certain distance, so that the user's fingers are placed in the gap between the first shell 11 and the second shell 12, thereby holding the first shell 11 and the second shell 12 and rotating them in opposite directions, thereby putting the electronic device 1 in the unfolded state.

[0048] It is worth noting that when the first magnetic module 21 is flipped, it can be flipped along its own central axis, in which case the first magnetic module 21 can be understood as self-rotation, or it can also rotate along the axis outside the first magnetic module 21, in which case the first magnetic module 21 can be understood as revolution. In addition, the preset angle of flipping the first magnetic module 21 can be understood as that the magnetic pole of the original lower end of the first magnetic module 21 can be facing upward, in other words, the component of the vertical line of the lower end surface can be facing upward, so that it can repel the second magnetic module 22 magnetically. The above content can also be understood as that the angle between the vertical line of the lower end surface of the first magnetic module 21 and the vertical line of the upper end surface of the second magnetic module 22 after flipping is greater than -90° and less than 90°, and the preset angle can be understood as greater than 90° and less than 270°. Optionally, when the preset angle is 180°, the magnetic matching effect of the first magnetic module 21 and the second magnetic module 22 is best.

[0049] In summary, in this embodiment, the first housing 11 and the second housing 12 can be automatically separated only by reversing the polarity of the first magnetic module 21 , thereby realizing automatic unfolding of the electronic device 1 , and the operation is simple.

[0050] Please refer to Figure 6-Figure 8 , Figure 6 This is a schematic diagram of an electronic device in another embodiment of the present application when it is in an unfolded state. Figure 7 for Figure 6 Schematic diagram of part of the structure of the electronic device shown. Figure 8 for Figure 7 The electronic device 1 is a schematic diagram of a partial structure when it is to be unfolded. In this embodiment, the electronic device 1 further includes a rotating device 40, the rotating device 40 is arranged on the first housing 11, the first magnetic module 21 is arranged on the rotating device 40, and the rotating device 40 can drive the first magnetic module 21 to flip.

[0051] The electronic device 1 may further be provided with a rotating device 40, and the rotating device 40 is installed in the first housing 11, for example, the rotating device 40 is installed in the first housing 11. At the same time, the first magnetic module 21 is installed in the rotating device 40, and the rotating device 40 itself can move. Therefore, by controlling the movement of the rotating device 40, the first magnetic module 21 arranged on the rotating device 40 can be accurately controlled to flip, which can reduce the control difficulty and improve the control accuracy. As for the specific structure of the rotating device 40, this application provides a variety of specific implementations, which will be introduced one by one below.

[0052] In this embodiment, the rotating device 40 includes a motor 42 and a rotating shaft 41. The output shaft 420 of the motor 42 is connected to the rotating shaft 41. The first magnetic module 21 is arranged on the rotating shaft 41. The motor 42 can drive the rotating shaft 41 to rotate, thereby flipping the first magnetic module 21.

[0053] In one embodiment, the rotating device 40 may include a motor 42 and a rotating shaft 41, and the output shaft 420 of the motor 42 may be connected to the rotating shaft 41. When the motor 42 is working, the output shaft 420 may rotate, thereby driving the rotating shaft 41 to rotate. Optionally, the output shaft 420 of the motor 42 may be connected to the central axis of the rotating shaft 41, thereby allowing the rotating shaft 41 to rotate along its own axis. The first magnetic module 21 may be arranged on the rotating shaft 41, and when the motor 42 drives the rotating shaft 41 to rotate, the rotating shaft 41 can drive the first magnetic module 21 to flip. In summary, the present embodiment only needs to control the working parameters of the motor 42 to accurately control the flipping angle of the first magnetic module 21, which can further reduce the control difficulty and improve the control accuracy.

[0054] Optionally, the first magnetic module 21 can be arranged on the curved surface of the rotating shaft 41, so that the first magnetic module 21 can revolve around the central axis of the rotating shaft 41, which can reduce the difficulty of connecting the first magnetic module 21 to the rotating shaft 41. Alternatively, the rotating shaft 41 can pass through the central axis of the first magnetic module 21, so that the central axis of the first magnetic module 21 coincides with the central axis of the rotating shaft 41, so that the first magnetic module 21 can rotate, which can reduce the rotation radius of the first magnetic module 21 and reduce the space occupied by the first magnetic module 21 inside the first housing 11.

[0055] In this embodiment, the electronic device 1 also includes a processor 50, which is electrically connected to the motor 42. The processor 50 is used to receive a flip signal. The processor 50 can control the motor 42 to rotate the shaft 41 according to the flip signal, thereby driving the first magnetic module 21 to flip the preset angle.

[0056] In addition to the above components, the electronic device 1 may also include a processor 50, which may be disposed in the first housing 11 or in the second housing 12, or part of the processor 50 may be disposed in the first housing 11, and the rest of the processor 50 may be disposed in the second housing 12, and this embodiment is not limited here. However, no matter where the processor 50 is disposed, the processor 50 may be electrically connected to the motor 42 through a wire or the like, so that the processor 50 may be used to control the working parameters of the motor 42. Specifically, the processor 50 may receive a flip signal in various ways, and then the processor 50 may control the working parameters of the motor 42 according to the specific content of the flip signal, so that the motor 42 works to drive the rotating shaft 41 to rotate, thereby driving the first magnetic module 21 to flip a preset angle. In summary, the processor 50 may automatically control the motor 42 to work so that the first magnetic module 21 flips a preset angle, without manually controlling the motor 42, and the control difficulty may be further reduced. As for how the processor 50 receives the flip signal, the present application provides a variety of specific implementations, which will be introduced one by one below.

[0057] In this embodiment, the electronic device 1 further includes a button 60 , and the button 60 is electrically connected to the processor 50 . The flip signal can be sent to the processor 50 by pressing the button 60 .

[0058] In addition to the above components, the electronic device 1 may also include a button 60, which may be arranged on the first housing 11 and / or the second housing 12. For example, the button 60 may be arranged on the first housing 11, or the button 60 may be arranged on the second housing 12, or the button 60 may be arranged on both the first housing 11 and the second housing 12. Regardless of where the button 60 is arranged, the button 60 can be electrically connected to the processor 50 through a wire. When the user presses the button 60, the button 60 can generate a flip signal and transmit the flip signal to the processor 50, so that the processor 50 can receive the flip signal from the button 60, and finally control the first magnetic module 21 to flip a preset angle through the motor 42 and the rotating shaft 41. When you want to flip again, you only need to press the button 60 again. In summary, by adding and pressing the button 60, a flip signal can be sent to the processor 50, which can improve the user's operability.

[0059] It is worth noting that the above-mentioned pressing of the key 60 does not only include the user's finger abutting on the key 60 and applying a large force, thereby causing the key 60 to move relative to the housing. The user's finger touches and abuts on the key 60, and a capacitive sensor is set on the key 60 to generate a flip signal, but at this time the key 60 is in a stationary state, which can also be called pressing the key 60.

[0060] In another embodiment, the user can touch the corresponding function icon on the display screen to send a flip signal to the processor 50, without adding a button 60, further reducing the difficulty of operation. In other embodiments, the electronic device 1 can also send a flip signal to the processor 50 by recognizing fingerprints, sounds, irises, etc., which can also further reduce the difficulty of operation.

[0061] Please refer to Figure 9-11 , Fig. 9 This is a schematic diagram of an electronic device in an unfolded state in yet another embodiment of the present application. Fig.10 for Fig. 9 Schematic diagram of part of the structure of the electronic device shown. Fig.11 for Fig.10 The schematic diagram of the partial structure of the electronic device shown in the figure when it is to be unfolded. In this embodiment, the electronic device 1 further includes a folding device 30, and the opposite ends of the folding device 30 are respectively connected to the first shell 11 and the second shell 12, and the rotating device 40 includes a rotating shaft 41 and an elastic member 43, the rotating shaft 41 is arranged on the first shell 11, and the first magnetic module 21 is arranged on the rotating shaft 41, and one end of the elastic member 43 is connected to the folding device 30, and the other end is connected to the rotating shaft 41. Wherein, when the electronic device 1 is from the unfolded state to the folded state, the first shell 11 and the rotating shaft 41 rotate relative to the folding device 30, so that the elastic member 43 is in a deformed state, and the rotating shaft 41 is limited to the first shell 11. When the electronic device 1 is to be from the folded state to the unfolded state, the rotation can rotate relative to the first shell 11, and the elastic member 43 in a deformed state can drive the rotating shaft 41 to rotate. When the electronic device 1 changes from the folded state to the unfolded state, the first housing 11 and the shaft 41 rotate in the opposite direction relative to the folding device 30, so that the shaft 41 is driven to rotate in the opposite direction by the elastic member 43. When the electronic device 1 is in the unfolded state, the shaft 41 can be re-confined to the first housing 11.

[0062] The folding device 30 has been described in detail above in this application, and this embodiment will not be described in detail here. In another embodiment, the rotating device 40 is composed of a rotating shaft 41 and an elastic member 43. The rotating shaft 41 can be set on the first shell 11, and the rotating shaft 41 can rotate relative to the first shell 11. The first magnetic module 21 can also be set on the rotating shaft 41 as mentioned in the above embodiment. As for how to set this embodiment specifically, it will not be described in detail here. One end of the elastic member 43 can be connected to the folding device 30, and the other end can be connected to the rotating shaft 41. Through the mutual cooperation between the elastic member 43 and the rotating shaft 41, the rotating shaft 41 can be controlled to rotate.

[0063] Specifically, when the electronic device 1 is in the unfolded state, the elastic member 43 is in a balanced state, and the rotating shaft 41 and the first magnetic module 21 are fixed. When the electronic device 1 changes from the unfolded state to the folded state, since the first shell 11 rotates relative to the folding device 30, the rotating shaft 41 is driven to rotate relative to the folding device 30, so that the other end of the elastic member 43 also rotates relative to the folding device 30. However, since one end of the elastic member 43 is fixed, the elastic member 43 can be in a deformed state, and the elastic member 43 in the deformed state can drive the rotating shaft 41 to rotate relative to the first shell 11. However, in this case, the present embodiment can control the rotating shaft 41 to be limited to the first shell 11, and the rotating shaft 41 is restricted from rotating. At this time, the elastic member 43 is always in a deformed state, so that the first magnetic module 21 and the second magnetic module 22 can be magnetically attracted to each other, so that the first shell 11 is connected to the second shell 12.

[0064] When the electronic device 1 is to be unfolded from the folded state, that is, when the electronic device 1 is to be unfolded but has not yet been unfolded, the present embodiment can release the limiting relationship between the rotating shaft 41 and the first housing 11, so that the rotating shaft 41 can rotate relative to the first housing 11. At this time, the elastic member 43 in the deformed state can drive the rotating shaft 41 to rotate by releasing the elastic potential energy at its other end, thereby achieving the purpose of flipping the first magnetic module 21. In this way, the first magnetic module 21 and the second magnetic module 22 can be magnetically repelled, so that the first housing 11 and the second housing 12 are separated from each other by a certain distance.

[0065] Then, when the electronic device 1 is changed from the folded state to the unfolded state, since the rotating shaft 41 and the first housing 11 are still in the released state, when the first housing 11 rotates in the opposite direction relative to the folding device 30, the rotating shaft 41 and the other end of the elastic member 43 can also rotate in the opposite direction relative to the folding device 30, and since one end of the elastic member 43 is fixed, the elastic member 43 can still be in a deformed state. However, the deformation state at this time is opposite to the deformation state during the folding process, that is, the elastic force is opposite, and since the rotating shaft 41 can rotate relative to the first housing 11 at this time, the elastic member 43 in the deformed state can drive the rotating shaft 41 to rotate in the opposite direction, thereby causing the first magnetic module 21 to flip back in the opposite direction, so that the magnetic poles facing each other of the first magnetic module 21 and the second magnetic module 22 are opposite.

[0066] When the electronic device 1 is in the unfolded state, the first magnetic module 21 flips back to its original position, and the rotating shaft 41 is re-positioned on the first housing 11 to facilitate the next operation.

[0067] In summary, this embodiment can control the flipping of the first magnetic module 21 through the rotating shaft 41 by controlling the limiting relationship between the elastic member 43 and the first shell 11. The solution is simple, which can reduce the control difficulty, eliminate the motor 42 structure, and reduce the cost of the electronic device 1.

[0068] In this embodiment, the first housing 11 is provided with a first limiting portion 71, and the first limiting portion 71 can move relative to the first housing 11, and the rotating shaft 41 is provided with a second limiting portion 72, and the first limiting portion 71 cooperates with the second limiting portion 72 to limit the rotating shaft 41 to the first housing 11. When the electronic device 1 is to be moved from the folded state to the unfolded state, the first limiting portion 71 moves relative to the first housing 11, so that the first limiting portion 71 is separated from the second limiting portion 72. When the electronic device 1 is in the unfolded state, the first limiting portion 71 moves in the opposite direction relative to the first housing 11, so that the first limiting portion 71 is connected to the second limiting portion 72.

[0069] In this embodiment, a first limiting portion 71 can be provided on the first housing 11, and the first limiting portion 71 can move relative to the first housing 11, for example, the first limiting portion 71 can slide, rotate, etc. relative to the first housing 11. At the same time, a second limiting portion 72 can be provided on the rotating shaft 41, and the limiting relationship between the rotating shaft 41 and the first housing 11 can be controlled by the cooperation between the first limiting portion 71 and the second limiting portion 72. Optionally, the first limiting portion 71 includes but is not limited to a limiting protrusion, the limiting protrusion can slide relative to the first housing 11, and the limiting protrusion can slide along the axis direction of the rotating shaft 41. The second limiting portion 72 includes but is not limited to a limiting groove, which is provided at one end of the rotating shaft 41 close to the limiting protrusion and extends along the axis direction of the rotating shaft 41. Of course, in other embodiments, the first limiting portion 71 and the second limiting portion 72 can also be other structures, and this embodiment is only schematically described with the limiting protrusion and the limiting groove.

[0070] When the electronic device 1 changes from the unfolded state to the folded state, the limiting protrusion is arranged in the limiting groove. At this time, the limiting protrusion can be used to limit the rotating shaft 41 on the first housing 11 to prevent the rotating shaft 41 from rotating. Therefore, even if the elastic member 43 is in an elastic state, the rotating shaft 41 will not rotate. When the electronic device 1 is to change from the folded state to the unfolded state, the limiting protrusion can be slid in a direction close to the first housing 11 and away from the rotating shaft 41, so that the limiting protrusion is separated from the limiting groove. At this time, without the restriction of the limiting protrusion, the elastic member 43 in the elastic state can rotate the rotating shaft 41, thereby turning the first magnetic module 21 over.

[0071] Then, when the electronic device 1 is moved from the folded state to the unfolded state, the limiting protrusion is still controlled to separate from the limiting groove, and the elastic member 43 can drive the rotating shaft 41 to rotate in the opposite direction, thereby causing the first magnetic module 21 to flip in the opposite direction. When the electronic device 1 is in the unfolded state, the limiting protrusion can be slid in a direction away from the first housing 11 and close to the rotating shaft 41, so that the limiting protrusion is reset in the limiting groove, and the limiting protrusion can be used again to limit the rotating shaft 41, so that the rotating shaft 41 cannot rotate.

[0072] In summary, in this embodiment, the limiting relationship between the rotating shaft 41 and the first shell 11 can be controlled by the cooperation between the first limiting portion 71 and the second limiting portion 72. The solution is simple, the structure can be simplified, and the control difficulty can be further reduced.

[0073] Optionally, the electronic device 1 may further include a button 60, which is disposed on the first housing 11. The button 60 may be connected to the first limiting portion 71. By controlling the button 60 to move relative to the first housing 11, the first limiting portion 71 may be synchronously controlled to move relative to the first housing 11, thereby connecting or separating the first limiting portion 71 from the second limiting portion 72. Therefore, the user only needs to control the button 60 on the first housing 11 to control the first limiting portion 71, which is simple to operate.

[0074] Please refer to Fig.12 , Fig.12 This is a schematic diagram of an electronic device in yet another embodiment of the present application when it is in an unfolded state. In this embodiment, the electronic device 1 further includes a processor 50, and the processor 50 is electrically connected to the first magnetic module 21 and the second magnetic module 22. When the electronic device 1 changes from the unfolded state to the folded state, the processor 50 controls the polarity of the first magnetic module 21 to be opposite to the polarity of the second magnetic module 22, so that the first magnetic module 21 and the second magnetic module 22 can be magnetically attracted to each other. When the electronic device 1 is to change from the folded state to the unfolded state, the processor 50 controls the polarity of the first magnetic module 21 to be the same as the polarity of the second magnetic module 22, so that the first magnetic module 21 and the second magnetic module 22 can be magnetically repelled.

[0075] The electronic device 1 may further include a processor 50, which may be disposed in the first housing 11 or in the second housing 12, or part of the processor 50 may be disposed in the first housing 11, and the rest of the processor 50 may be disposed in the second housing 12, and this embodiment is not limited here. In this embodiment, the magnet in the first magnetic module 21 and the magnet in the second magnetic module 22 are electromagnets, which are devices that generate magnetism through electric current. When electric current passes through a wire, a magnetic field is generated around the wire, thereby forming an electromagnet. The magnetism of an electromagnet can be controlled by changing the magnitude and direction of the current, and the magnetism disappears after power is turned off.

[0076] The first magnetic module 21 and the second magnetic module 22 can be connected to the processor 50 via wires, and the processor 50 can be used to control the polarity of the first magnetic module 21 and the polarity of the second magnetic module 22. When the electronic device 1 is in the unfolded state, there is no need for the first magnetic module 21 and the second magnetic module 22 to cooperate, so the processor 50 does not need to control the first magnetic module 21 and the second magnetic module 22, and the first magnetic module 21 and the second magnetic module 22 have no magnetism.

[0077] When the electronic device 1 changes from an unfolded state to a folded state, the processor 50 can respectively control the polarity of the first magnetic module 21 and the polarity of the second magnetic module 22, so that the polarity of the first magnetic module 21 is opposite to the polarity of the second magnetic module 22. In this way, the magnetic attraction between the first magnetic module 21 and the second magnetic module 22 can be utilized to make the first shell 11 tightly connected to the second shell 12.

[0078] When the electronic device 1 is to be moved from a folded state to an unfolded state, the processor 50 can again control the polarity of the first magnetic module 21 and the polarity of the second magnetic module 22 to make the polarity of the first magnetic module 21 the same as the polarity of the second magnetic module 22. In this way, the magnetic repulsion between the first magnetic module 21 and the second magnetic module 22 can be utilized to separate the first shell 11 and the second shell 12 that were originally tightly fitted together by a certain distance, so that the user's fingers can be placed in the gap between the first shell 11 and the second shell 12, thereby holding the first shell 11 and the second shell 12 and rotating them in opposite directions, thereby putting the electronic device 1 in the unfolded state.

[0079] When the electronic device 1 is in the unfolded state again, the processor 50 may stop controlling the first magnetic module 21 and the second magnetic module 22 , so that the magnetism of the first magnetic module 21 and the magnetism of the second magnetic module 22 disappear.

[0080] In summary, in this embodiment, the polarity of the first magnetic module 21 and the second magnetic module 22 can be controlled by the processor 50, so as to realize the folding and unfolding of the electronic device 1, and the structure is simple and no complicated mechanical structure is required. In addition, there is no need to control the first magnetic module 21 and the second magnetic module 22 in the unfolded state, which can save power.
