[0027] The electronic device and the control method of the electronic device provided by the embodiments of the present application will be described in detail below in combination with the specific embodiments and application scenarios. Figures 1 to 6 , the electronic device and the control method of the electronic device provided by the embodiments of the present application will be described in detail below in combination with the specific embodiments and application scenarios.

[0028] According to an embodiment of the present application, an electronic device is provided, referring to Figures 1 to 4 , the electronic device includes a first circuit board 1, the first circuit board 1 includes a conductive layer 101 and a protective layer 102 disposed on the conductive layer 101; the protective layer 102 is provided with a first magnetic member 103, or one side of the protective layer 102 is provided with a first magnetic member 103. Referring to Figure 5 , the electronic device further includes a second magnetic member 3, the second magnetic member 3 is arranged opposite to the first magnetic member 103, and the first magnetic member 103 and the second magnetic member 3 repel each other in the process that the first circuit board 1 approaches the second magnetic member 3.

[0029] In addition, in some examples of the present application, the electronic device further comprises a display screen and a device shell, the display screen is covered on the device shell, the display screen and the device shell form a containing cavity, and the first circuit board 1 and the second magnetic member 3 are arranged in the containing cavity.

[0030] In this case, referring to Figure 5 , the electronic device is a folding electronic device, which can comprise a first body 4 and a second body 5 connected by rotation.

[0031] The folding screen can be freely switched between the folded state and the unfolded state, and the user can adjust the size of the display screen according to the needs, and the two ends of the first circuit board 1 are connected with the first body 4 and the second body 5 respectively. When the folding screen is switched between the folded state and the unfolded state, the first circuit board 1 can be bent or unfolded with the folding screen. In this process, when the first circuit board 1 is close to the second magnetic member 3, the repulsive magnetic force between the first magnetic member 103 and the second magnetic member 3 is generated, so that the first circuit board 1 will not be in frequent contact with the related components (arranged in the direction of the second magnetic member, or directly bearing the second magnetic member) to produce friction loss.

[0032] It can be understood that the electronic device provided by the embodiments of the present application is not limited to the folding screen electronic device, and can also be a general electronic device, which is not specifically limited herein.

[0033] In the embodiments of the present application, the first circuit board 1 itself is a multi-layer composite structure.

[0034] For example, the first circuit board 1 comprises a conductive layer 101, a protective layer 102 is arranged on the conductive layer 101, and a magnetic conductive material is added in the protective layer 102, so as to form the first magnetic member 103 in the protective layer 102 or on one side of the protective layer 102, referring to Figure 2 and Figure 3 .

[0035] It should be noted that the protective layer 102 is arranged on both surfaces of the conductive layer 101, so as to completely wrap the conductive layer 101, thereby being able to completely protect the conductive layer 101, referring to Figure 1 .

[0036] For example, the protective layer 102 is arranged on one surface of the conductive layer 101, and when the protective layer 102 is arranged in the electronic device, the protective layer 102 is arranged towards the second magnetic member 3, so that the first magnetic member 103 in the protective layer 102 is opposite to and close to the second magnetic member 3.

[0037] In the embodiment of the present application, the second magnetic member 3 is arranged inside the electronic device.

[0038] For example, the second magnetic member 3 is arranged on a part which is easy to contact the first circuit board 1, and the second magnetic member 3 is designed to be opposite to the first magnetic member 103. The main function of the second magnetic member 3 is that the repulsive magnetic force between the second magnetic member 3 and the first magnetic member 103 can be used as a driving force to drive the first circuit board 1 to avoid contacting the related parts inside the electronic device, so that the first circuit board 1 does not have contact friction loss, thereby prolonging the service life of the circuit board and overcoming the defects in the prior art.

[0039] In the embodiment of the present application, the first magnetic member 103 is arranged in the protective layer 102 of the first circuit board 1 or on one side of the protective layer 102, and the second magnetic member 3 opposite to the first magnetic member 103 is arranged in the electronic device. The repulsive magnetic force between the second magnetic member 3 and the first magnetic member 103 can be used to avoid the friction loss of the first circuit board 1 caused by contacting the related parts, thereby effectively prolonging the service life of the first circuit board 1. Thus, it is helpful to prolong the service life of the electronic device.

[0040] That is, in the embodiment of the present application, the protective layer 102 with a magnetic conductive material is used to replace the ordinary protective layer, and the magnetic force generated after the magnetic conductive material is energized is used to reduce the contact friction loss of the circuit board.

[0041] In some examples of the present application, when the first magnetic member 103 moves towards the second magnetic member 3, the first magnetic member 103 repels the second magnetic member 3.

[0042] It can be understood that when the first circuit board 1 moves towards the direction of the second magnetic member 3, the first magnetic member 103 moves towards the second magnetic member 3, and in this case, the repulsive magnetic force between the first magnetic member 103 and the second magnetic member 3 is triggered. At this time, the related parts arranged in the direction of the second magnetic member 3 can keep a certain distance from the first circuit board 1 to avoid direct contact, thereby avoiding the friction loss caused by contact.

[0043] In some examples of the present application, referring to Figure 2 and Figure 3 the first circuit board 1 is a flexible circuit board (FPC) which can be bent;

[0044] The first circuit board 1 is provided with an electrical terminal 105, and the first magnetic member 103 is electrically connected with the electrical terminal 105 to generate a magnetic force repelling the second magnetic member 3. The repulsion between the first magnetic member 103 and the second magnetic member 3 causes the first circuit board 1 to move away from the second magnetic member 3.

[0045] In the embodiment of the present application, the first magnetic member 103 is made of a material which does not have a magnetic force by itself and generates a magnetic force after being electrified. That is, the first magnetic member 103 is electrically connected with the electrical terminal 105, and generates a magnetic force repelling the second magnetic member 3 after being electrified.

[0046] The reason for adopting this design in the embodiment of the present application is that if a material with a magnetic force is directly added to the protective layer 102, the magnetic material may interfere with the wiring of the first circuit board 1. Therefore, the embodiment of the present application is designed according to the principle of "electromagnetism".

[0047] In some examples of the present application, referring to Figure 2 and Figure 3 the electrical terminal 105 is arranged on both sides of the first circuit board 1; the first circuit board 1 has a bending area 106 which is located between the electrical terminals 105 on both sides of the first circuit board 1;

[0048] The first magnetic member 103 includes a first part 1031 located in the bending area 106 and a second part 1032 located between the bending area 106 and the electrical terminal 105, and the width of the first part 1031 is greater than the width of the second part 1032.

[0049] The first magnetic member 103 is a ferrite material arranged in or on one side of the protective layer 102, and the width of the first magnetic member 103 gradually narrows towards the direction close to the electrical terminal 105.

[0050] In the embodiment, the width direction of the first magnetic member 103 is the same as the width direction of the first circuit board 1, and the electrical terminal 105 is arranged on both sides of the first magnetic member 103 along the length direction of the first circuit board 1. It can be understood that the width direction of the first magnetic member 103 is perpendicular to the direction of the current in the first magnetic member 103.

[0051] For example, referring toFigure 2 and Figure 3 The power connection terminals 105 are arranged in two, and the two power connection terminals 105 are arranged on the two sides of the first circuit board 1, and the two ends of the first magnetic member 103 are electrically connected to the two power connection terminals 105 one by one, and one of the power connection terminals 105 can also be grounded.

[0052] In the embodiment of the present application, the width of the first magnetic member 103 in the direction towards the power connection terminal 105 is variable, specifically, the width gradually narrows. This facilitates electrical connection with the power connection terminal 105. Designing the two side portions of the first magnetic member 103 to be gradually narrowed is also to enable the connection with the power connection terminal 105 to be concentrated at one point, which is more conducive to power supply of the power supply part, saves the number of terminals (pins) occupied by the first magnetic member 103 and the number of wires electrically connected to the first magnetic member 103, and can to some extent play a role in simplifying the circuit structure and saving costs.

[0053] In the embodiment of the present application, the first circuit board 1 has a bending area and can be bent to adapt to a folding screen electronic device.

[0054] The first magnetic member 103 includes the first portion 1031 and the second portion 1032, the first portion 1031 is located in the bending area 106, and the second portion 1032 is located between the bending area 106 and the power connection terminal 105

[0055] In the folding electronic device, the first circuit board 1 is located between the first body 4 and the second body 5 of the folding electronic device. When the folding electronic device is opened and closed, the bending area 106 of the first circuit board 1 is located in the middle area of the first circuit board 1. That is, the first portion 1031 is located in the middle area of the first circuit board 1. In the embodiment, the second portion 1032 is located on both sides of the first portion 1031, and it can be understood that in some embodiments, the second portion 1032 can be located on only one side of the first portion 1031.

[0056] When the folding electronic device is opened and closed, the bending area 106 of the first circuit board 1 will be more severely squeezed and will produce a certain displacement. Based on this, the width dimension of the first portion 1031 of the first magnetic member 103 located in the bending area 106 is designed to be greater than the width dimension of the second portion 1032 located between the bending area 106 and the power connection terminal 105. In this way, after the first magnetic member 103 generates a magnetic force, for example, due to power supply, the bending area 106 on the first circuit board 1 will generate a greater repulsive force to avoid the bending area 106 of the first circuit board 1 from contacting adjacent devices during movement, thereby better playing a role in protecting the circuit board.

[0057] In one specific example of the present application, referring to Figure 2 and Figure 3 The first magnetic member 103 has a rhombus shape in plan view. The rhombus design is consistent with the design that the first portion 1031 is wide and the second portions 1032 on both sides are gradually narrow. Meanwhile, the rhombus design can make the connection between the first magnetic member 103 (e.g. ferrite) and the power terminal 105 concentrated in one point, which is conducive to the power supply of the power supply part. In particular, it can be achieved that the first magnetic member 103 (e.g. ferrite) is powered by one wire, which can save the number of power terminals 105 occupied by the first magnetic member 103 and the bifurcation of the power supply wire electrically connected with the first magnetic member 103, thereby saving the manufacturing cost of the circuit board.

[0058] In some examples of the present application, the first magnetic member 103 is a magnetic sheet made of ferrite material, which is electrically connected with an external circuit. Under the action of an external current, the magnetic sheet is powered to generate a magnetic force repelling the second magnetic member 3.

[0059] Ferrite material itself does not have magnetism and needs to be powered to generate a magnetic force. It meets the design requirements of the present application.

[0060] The first magnetic member 103 can also use other magnetic materials known to those skilled in the art, and is not limited to the above-mentioned ferrite material. The present application does not make specific limitations here.

[0061] In some examples of the present application, the first magnetic member 103 can also be a coil, which is electrically connected with an external circuit. Under the action of an external current, the coil is powered to generate a magnetic force repelling the second magnetic member 3.

[0062] It should be noted that the structure of the first magnetic member 103 includes but is not limited to the above-mentioned magnetic sheet or coil. Those skilled in the art can design as needed, and the present application does not make specific limitations here.

[0063] In some examples of the present application, referring to Figure 5 , the electronic device includes a first body 4 and a second body 5 rotatably connected, and a second circuit board 2, referring to Figure 4 ; wherein the second magnetic member 3 is arranged in the protective layer of the second circuit board 2, or the second magnetic member 3 is arranged on one side of the protective layer of the second circuit board 2;

[0064] The two ends of the first circuit board 1 and / or the second circuit board 2 are connected with the first body 4 and the second body 5 respectively, the first magnetic member 103 and the second magnetic member 3 comprise ferrite material, and one side of the first circuit board 1 with the first magnetic member 103 is arranged opposite and close to one side of the second circuit board 2 with the second magnetic member 3.

[0065] The electronic device is for example a folding electronic device, which comprises a first body 4 and a second body 5, and the first body 4 and the second body 5 are arranged in a rotating connection, which can realize the folding and unfolding functions of the electronic device.

[0066] It can be understood that, in the electronic device, the second circuit board 2 is also used in addition to the first circuit board 1, the second magnetic member 3 can be arranged on the second circuit board 2, and the first magnetic member 103 and the second magnetic member 3 are opposite and close to each other. During the process that the first circuit board 1 approaches the second circuit board 2, the first circuit board 1 and the second circuit board 2 repel each other, so that they do not contact each other, thereby avoiding the friction loss between the two circuit boards.

[0067] In the embodiment of the present application, the second circuit board 2 is for example a multi-layer composite structure, which can be the same as the first circuit board 1.

[0068] Specifically, the second circuit board 2 comprises a conductive layer and a protective layer arranged on the conductive layer, and on this basis, the second magnetic member 3 is arranged in the protective layer, or the second magnetic member is arranged on one side of the protective layer.

[0069] In some examples of the present application, the first circuit board 1 and the second circuit board 2 are arranged in parallel.

[0070] The two ends of the first circuit board 1 and the second circuit board 2 are connected with the first body 4 and the second body 5 through the power connection terminals 105 respectively, and the bending area 106 of the first circuit board 1 and the bending area of the second circuit board 2 are opposite; the first magnetic member 103 comprises a first part 1031 located in the bending area 106 of the first circuit board 1 and a second part 1032 located between the bending area 106 of the first circuit board 1 and the power connection terminal 105, and the width of the first part 1031 is greater than the width of the second part 1032. The orthographic projection of the second magnetic member 3 on the first circuit board 1 covers the first magnetic member 103, so as to ensure that the repulsive force between the bending area 106 of the first circuit board 1 and the second circuit board 2 is maximum.

[0071] In the embodiments of the present application, the magnetic repulsion between the first magnetic member 103 and the second magnetic member 3 is controlled, so that the two circuit boards can be prevented from contacting each other, and thus the wear of the two circuit boards due to friction can be avoided. The first circuit board 1 and the second circuit board 2 are completely free from contact, and a certain gap is maintained between the two circuit boards by the repulsive force between the first magnetic member 103 and the second magnetic member 3. Thus, the wear due to contact can be avoided, and the service life of the circuit boards can be prolonged.

[0072] It should be noted that when the first circuit board 1 and the second circuit board 2 are arranged in an electronic device, the relative positions of the first circuit board 1 and the second circuit board 2 include but are not limited to being arranged in parallel with each other. Those skilled in the art can flexibly adjust the positional relationship between the two circuit boards according to the needs, and the embodiments of the present application do not make specific limitations here.

[0073] In some examples of the present application, one end of the first circuit board 1 is connected to the first body 4, and the other end of the first circuit board 1 is connected to the second body 5; the second circuit board 2 is connected to the first circuit board 1; the first magnetic member 103 includes a first part 1031 located in the bending area 106 of the first circuit board 1 and a second part 1032 located between the bending area 106 of the first circuit board 1 and the power connection terminal 105, and the width of the first part 1031 is greater than the width of the second part 1032; the second magnetic member 3 covers the first magnetic member 103 in orthographic projection on the first circuit board 1. The shapes of the first magnetic member 103 and the second magnetic member 3 are the same, so that the orthographic projections of the two can completely coincide. In this way, during the approach of the first circuit board 1 to the second circuit board 2, the first magnetic member 103 and the second magnetic member 3 can generate uniformly distributed repulsive force, so that a reasonable gap is formed and maintained between the two circuit boards, which can prevent the two circuit boards from contacting and wearing each other, and also can prevent the circuit boards from being turned and deflected.

[0074] In the embodiments of the present application, referring to Figure 3 , the first circuit board 1 further includes two power supply parts 107, for example. The two power supply parts 107 are arranged on the two sides of the first circuit board 1, and are electrically connected to the conductive layer 101. The power connection terminal 105 can be electrically connected to the power supply part 107, or be led out by the power supply part 107.

[0075] For example, the power supply part 107 is arranged as a BTB connector. Those skilled in the art can flexibly arrange the specific form of the power supply part 107 according to the needs, and the present application does not make limitations here.

[0076] In some examples of the present application, referring toFigure 1 The first circuit board 1 further comprises a glue layer 104, the conductive layer 101 is provided on the glue layer 104, the protective layer 102 is provided on the glue layer 104, and the protective layer 102 is fixed with the conductive layer 101 through the glue layer 104;

[0077] The first magnetic piece 103 and the conductive wire electrically connected with the first magnetic piece 103 are arranged in the protective layer 102, and the protective layer 102 is an insulating material to insulate the first magnetic piece 103 from the conductive layer 101;

[0078] The power connection terminal 105 is formed on the conductive layer 101, and the conductive wire is electrically connected with the power connection terminal 105 to generate a magnetic force repulsive to the second magnetic piece 3.

[0079] The material of the protective layer 102 is, for example, liquid plastic, which is an insulating material. The insulating protective layer 102 can isolate the conductive layer 101 and the first magnetic piece 103 to avoid the influence of the first magnetic piece 103 on the wiring on the conductive layer 101.

[0080] The protective layer 102 is wrapped outside the conductive layer 101.

[0081] It can be understood that the protective layer 102 is arranged on both surfaces of the conductive layer 101, which can better protect the conductive layer 101.

[0082] The glue layer 104 can fix the protective layer 102 and has the functions of insulation and protection to a certain extent.

[0083] The conductive layer 101 is, for example, a copper foil, which has the function of conducting electricity.

[0084] It should be noted that the electronic device can be a terminal or other device other than a terminal. For example, the electronic device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), and can also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, and the like, which are not limited herein.

[0085] According to another embodiment of the present application, a control method of an electronic device is provided, referring to Figure 6 , the control method comprises:

[0086] Step S1, obtaining a folding angle of the electronic device.

[0087] Step S2, in a case where the folding angle is greater than a preset angle, controlling the electronic device to energize the first magnetic member 103 and the second magnetic member 3, the first magnetic member 103 and the second magnetic member 3 being repulsive.

[0088] Since the circuit board in the electronic device is more likely to cause contact friction loss when switching between the folded state and the unfolded state, in the embodiments of the present application, the condition for triggering the first magnetic member 103 to generate a magnetic force is set to when the folding screen has a folding or unfolding action.

[0089] In some examples of the present application, referring to Figure 7 , the control method of the electronic device comprises the following steps:

[0090] Step S101, starting the electronic device angle detection.

[0091] That is, the folding angle of the electronic device can be detected by using a sensor, such as an angle sensor, provided in the electronic device. That is, after the electronic device is powered on, the electronic device angle detection function can be started.

[0092] Step S102, after step S101, performing electronic device angle judgment.

[0093] It can be understood that the sensor is started to detect the angle of the electronic device in the step S101, and then the angle of the electronic device can be determined according to the detected angle value.

[0094] For example, the processor CPU in the electronic device can obtain the current state of the electronic device according to the angle detected in the step S101, to determine whether the electronic device is in the open-close state, that is, whether the electronic device is switched between the unfolded state and the folded state.

[0095] In the step S103, when the angle of the electronic device is greater than 0, it is determined that the electronic device is in the open-close state, and in this case, the next step can be directly performed; otherwise, the angle of the electronic device is re-detected.

[0096] In the step S102, the angle of the electronic device is detected, and the angle of the electronic device is 0 when the electronic device is folded, that is, when the electronic device is closed.

[0097] In the step S104, when it is detected in the step S103 that the angle of the electronic device is greater than 0, the ferrite is powered.

[0098] In the step S105, the ferrite generates magnetism.

[0099] The ferrite is arranged in the protective layer 102 of the first circuit board 1 or on one side of the protective layer 102, to form a first magnetic member 103, which can generate magnetism after being powered. The first circuit board 1 and the second magnetic member 3, or the first circuit board 1 and the second circuit board 2 can generate repulsive magnetism.
