Along with the progress of science and technology, the age of large-screen intelligent electronic equipment is coming, and in order to solve the problem that the traditional large-screen straight board equipment is large in size and inconvenient to carry, the electronic equipment with a foldable function is generated. When the user needs large screen display, the electronic equipment can be unfolded to provide a large screen picture for the user, so that the large screen display requirement of the user is met; when the user needs to carry about, the electronic equipment can be folded to reduce the space required by storage, so that the electronic equipment is convenient for the user to carry about.

When the electronic equipment is in a folded state, the attraction force of the magnets on the electronic equipment is large, so that the electronic equipment is difficult to unfold.

Disclosure of Invention

The embodiment of the application provides electronic equipment and a control method thereof, which can solve the problem that the electronic equipment in a folded state is difficult to unfold.

In order to achieve the above purpose, the application adopts the following technical scheme:

in a first aspect, an electronic device is provided. The electronic device includes a first housing, a second housing, a rotating mechanism, and a processor. The first housing includes a first magnetic attraction member. The second housing includes a second magnetic attraction member. At least one of the first magnetic attraction member and the second magnetic attraction member includes an electrically controlled magnetic attraction member. The electrically controlled magnetic attraction piece comprises a magnet and a coil, and the coil is wound around the magnet. The rotating mechanism is respectively connected with the first shell and the second shell. The first housing and the second housing are switched between a folded state and an unfolded state by a rotation mechanism. The processor is coupled with the coil and is used for controlling the energizing of the coil to form an electromagnetic field. The magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the fixed magnetic field formed by the magnet, so that the attraction force between the first magnetic attraction piece and the second magnetic attraction piece is reduced.

The electronic device may include a flexible screen and a folding device. Wherein the flexible screen may be a touch screen. The flexible screen includes a first portion, a second portion, and a third portion, the third portion being positioned between the first portion and the second portion.

The electronic device may also include an auxiliary screen. The auxiliary screen may be displayed toward the user with the electronic device in a collapsed state to help the user understand time, calendar, etc. The auxiliary screen may be a rigid screen or a flexible screen, which is not limited by the present application.

The folding device comprises a first shell, a second shell and a rotating mechanism. The first housing is for securing and supporting a first portion of the flexible screen. The second housing is used to secure and support a second portion of the flexible screen. The rotating mechanism is used for supporting the third part of the flexible screen. The rotating mechanism is located between the first shell and the second shell, the rotating mechanism is connected with the first shell and the second shell respectively, and the first shell and the second shell are rotatably connected through the rotating mechanism, so that relative rotation between the first shell and the second shell is achieved.

The first housing and the second housing may both be provided with mounting spaces, and electronic components of the electronic device described above may be distributed in the housings on both sides. The processor may be mounted in the mounting space of the first housing or in the mounting space of the second housing, for example.

The first housing may include a first magnetic attraction member and the second housing may include a second magnetic attraction member. It is understood that the first magnetic attraction piece is arranged in the installation space of the first shell, and the second magnetic attraction piece is arranged in the installation space of the second shell.

When the folding device is in a folding state, the first magnetic attraction piece and the second magnetic attraction piece are attracted to each other, so that the folding device is kept in the folding state under the condition of no external force.

In some examples, the first magnetic attraction member may be located at an edge position of the first housing, and the second magnetic attraction member may be located at an edge position of the second housing.

For example, the first magnetic attraction member may be located at an edge of the first housing remote from the rotation mechanism. For example, two first magnetic attraction pieces are located at both ends of the edge of the first housing away from the rotating mechanism. The second magnetic attraction member may be located at an edge of the second housing remote from the rotation mechanism. For example, two second magnetic attraction pieces are located at both ends of the edge of the second housing away from the rotating mechanism.

The first magnetic attraction piece is located at the edge of the first shell, and the second magnetic attraction piece can be located at the edge of the second shell away from the rotating mechanism. Therefore, the attraction effect of the edge positions of the first shell and the second shell when the electronic equipment is in the folded state can be well ensured, and the electronic equipment is prevented from being unfolded easily.

The first magnetic attraction piece can be an electric control magnetic attraction piece, and the second magnetic attraction piece can be a permanent magnet; alternatively, the first magnetic attraction member may be a permanent magnet, and the second magnetic attraction member may be an electrically controlled magnetic attraction member; alternatively, the first magnetic attraction member and the second magnetic attraction member may be both electrically controlled magnetic attraction members.

The electrically controlled magnetic attraction member refers to a structure in which the strength of a magnetic field formed by a substance can be changed by an electrical signal (e.g., current, voltage).

The processor can reduce the magnetic field intensity of the electric control magnetic attraction piece by changing the electric signal provided to the electric control magnetic attraction piece, so that the attraction force between the first magnetic attraction piece and the second magnetic attraction piece is reduced, and the user can conveniently unfold the electronic equipment.

The electrically controlled magnetic attraction piece comprises a magnet and a coil. The magnets form a fixed magnetic field. The coil is wound around the magnet. The processor is also coupled with the coil, and controls the coil to be electrified to form an electromagnetic field; wherein, the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the fixed magnetic field.

The magnet may comprise a permanent magnet, for example a magnet. The magnets may be in the shape of a bar magnet, a cylindrical magnet, or the like. The permanent magnet can form a permanent magnetic field due to the characteristics of the permanent magnet, and magnetic lines of force of the permanent magnetic field point to the S pole from the N pole. For ease of understanding, the following description will be given taking the permanent magnet as an example, and the fixed magnetic field formed by the magnet is the permanent magnetic field formed by the magnet.

The coil may comprise a metallic material of relatively high conductivity such as copper, tungsten, silver, etc. The coil may be wound around the permanent magnet in a plurality of turns in one direction. The number of turns of the coil winding magnet may be 5, 20, 50, 100 or the like. In practice, the number of turns of the coil around the magnet may depend on factors such as the thickness of the coil, the spacing between adjacent turns, the length of the magnet, etc.

The coil forms an electromagnetic field when energized. In an embodiment of the application, the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the permanent magnet.

In some examples, the processor may control the coil to be de-energized. Under the condition that the coil is not electrified, the magnetic field formed by the electric control magnetic attraction piece can be a permanent magnetic field formed by the magnet.

In other examples, the processor may control the coil to be energized. In the case of the coil being energized, the magnetic field formed by the electronically controlled magnetic attraction may be a superimposed magnetic field between the permanent magnetic field formed by the magnet and the electromagnetic field formed by the coil, as the coil will form an electromagnetic field.

For example, the processor controls the current value of the current on the coil to be equal to the first current value, and the coil forms a first electromagnetic field. The magnetic field strength of the first electromagnetic field may be less than the magnetic field strength of the permanent magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the permanent magnet, the electric control magnetic attraction piece forms the magnetic field direction of the first superimposed magnetic field, which is the same as the magnetic field direction of the permanent magnet; and the electric control magnetic attraction piece forms the magnetic field intensity of the first superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the permanent magnetic field and the magnetic field intensity of the first electromagnetic field.

For another example, the processor controls the current value of the current on the coil to be equal to the second current value, and the coil forms a second electromagnetic field. The second current value may be greater than the first current value, and thus the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the first electromagnetic field.

In some possible implementations, the magnetic field strength of the second electromagnetic field may be less than the magnetic field strength of the permanent magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the permanent magnet, the electric control magnetic attraction piece forms the magnetic field direction of a second superimposed magnetic field, which is the same as the magnetic field direction of the permanent magnet; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the permanent magnetic field and the magnetic field intensity of the second electromagnetic field.

In other possible implementations, the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the permanent magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the permanent magnet, the electric control magnetic attraction piece forms the magnetic field direction of a second superimposed magnetic field, which is the same as the magnetic field direction of the electromagnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the second electromagnetic field and the magnetic field intensity of the permanent magnetic field.

It will be appreciated that the electronically controlled magnetic attraction member 40 has a magnetic property opposite to that of the permanent magnet in the case where the current value of the current on the processor control coil is equal to the second current value.

In this embodiment, the processor may control the magnetic field strength of the electromagnetic field formed by the coil by controlling the electric signal on the coil, so as to change the magnetic field strength of the superimposed magnetic field formed by superimposing the electromagnetic field and the permanent magnetic field (i.e. the magnetic field strength of the magnetic field formed by the electrically controlled magnetic attraction pieces), reduce the magnetic force of mutual attraction between the magnetic attraction pieces on two sides of the folding, and thus reduce the opening force required for unfolding the electronic device, so that the user can easily unfold the electronic device in a scenario where the user wants to unfold the folding device by one hand or wants to unfold the folding device in a more effort-saving manner.

The embodiment of the application provides electronic equipment, which reduces the opening force required by unfolding the electronic equipment by reducing the magnetic force of mutual attraction between magnetic attraction pieces at two sides of folding, so that a user can easily unfold the electronic equipment in a scene of needing single-hand unfolding or needing to unfold the folding equipment in a labor-saving mode.

In some possible implementations of the first aspect, the electronic device further includes an inductor. The sensor is used for responding to the triggering operation and outputting a triggering signal. The processor is also coupled to the inductor and is further configured to control energizing of the coil in response to the trigger signal to form an electromagnetic field.

The inductor may be installed in the installation space of the first housing or may be located in the installation space of the second housing.

The sensor is used as a device for receiving user operation, and outputs different trigger signals to the controller according to trigger operation input by the user.

In some examples, the trigger operation includes at least a first trigger sub-operation and a second trigger sub-operation. The first trigger sub-operation may be a click operation on the screen, and the second trigger sub-operation may be a long press operation on the screen. It should be appreciated that any two operations that can be distinguished by the sensor can be used as a first trigger sub-operation and a second trigger sub-operation, respectively.

The trigger signal may include a first trigger sub-signal and a second trigger sub-signal. The sensor can correspondingly output different trigger sub-signals to the processor according to the received different trigger sub-operations. The sensor outputs a first trigger sub-signal in response to a first trigger sub-operation, and the sensor outputs a second trigger sub-signal in response to a second trigger sub-operation.

In this way, the sensor can output different trigger sub-signals to the processor to distinguish the user's trigger operation, thereby enabling the electronic device to make an opening force control that matches the user's mind.

In some possible implementations of the first aspect, the sensor includes at least one of a key, a touch screen, a camera, and a microphone.

The electronic device may also include electronic components such as keys, cameras, and microphones. These electronic components capable of sensing user operation may act as sensors. The sensor generates a trigger signal by sensing a trigger operation and provides the trigger signal to the processor.

For example, the electronic device may trigger the operation through key sensing, and the corresponding trigger operation may be a key operation such as double-clicking a volume key, clicking a trigger key, and the like. Also, for example, the electronic device may sense a triggering operation through the camera, and the corresponding triggering operation may be a gesture operation set by the user, a facial expression set by the user, or another suitable action. Further, for example, the electronic device may sense a triggering operation through the auxiliary screen, and the corresponding triggering operation may be a touch operation such as a screen sliding track, a screen clicking operation, and the like set by the user. Further, for example, the electronic device may sense a triggering operation through the microphone, and the corresponding triggering operation may be a voice command set by the user or a suitable sound command.

In this embodiment, a plurality of electronic components in the electronic device are used as the sensors, so that the abundant sensor forms can facilitate the user to input the triggering operation through various forms, and the convenience of inputting the triggering operation by the user is improved.

In some possible implementations of the first aspect, the electronic device further includes an ambient light sensor. An ambient light sensor is coupled to the processor. The ambient light sensor is used for collecting the ambient light brightness of the electronic device. And under the condition that the ambient light brightness is less than or equal to a preset brightness threshold value, the processor controls the electric control magnetic attraction piece to keep the magnetic field intensity.

The ambient light sensor may be installed in the installation space of the first housing or may be located in the installation space of the second housing.

The ambient light sensor is used for sensing ambient light brightness. The electronic device can adaptively adjust the light-emitting brightness of the flexible screen according to the perceived ambient light level. The ambient light sensor may also be used to automatically adjust white balance when taking a photograph. The ambient light sensor may also detect whether the electronic device is in a pocket to prevent false touches. For example, the ambient light sensor may collect ambient light level of an environment in which the electronic device is located and provide the ambient light level to the processor.

The processor also obtains the ambient light level provided by the ambient light sensor. The processor may compare the ambient light level to a preset brightness threshold. When the ambient light brightness is greater than or equal to the brightness threshold, the processor considers that the electronic equipment is not currently located in a pocket or other scene requiring the activation of the false touch prevention function, and therefore the false touch prevention function is not activated. Under the condition that the ambient light brightness is smaller than the brightness threshold value, the processor considers that the electronic equipment is currently in a scene such as a pocket and the like, which needs to start the false touch prevention function, so that the false touch prevention function is started.

The processor does not start the false touch prevention function, the electronic equipment is in the false touch prevention state, the processor can adjust the electric signal of the coil in the electric control magnetic attraction piece under the condition that the processor acquires the trigger signal, so that the magnetic field formed by the electric control magnetic attraction piece is changed, the attraction force between the first magnetic attraction piece and the second magnetic attraction piece is reduced, and the electronic equipment is convenient for users to expand.

The processor starts the false touch prevention function, the electronic equipment is in the false touch prevention state, the processor can not adjust the electric signal of the coil in the electric control magnetic attraction piece under the condition that the processor acquires the trigger signal, and the electric control magnetic attraction piece keeps the magnetic field intensity, so that attraction force between the first magnetic attraction piece and the second magnetic attraction piece cannot be changed.

In this embodiment, the electronic device may sense whether the electronic device is in the anti-false touch scene by means of the ambient light sensor, and enter the anti-false touch mode when the electronic device confirms that the electronic device is in the anti-false touch scene. Therefore, even if the electronic equipment receives the triggering operation input by a user, the electronic equipment can not adjust the electric signal of the coil in the electric control magnetic attraction piece, so that the opening force of the electronic equipment can not be changed, and the electronic equipment is prevented from being easily unfolded in an anti-false touch state.

In a second aspect, a control method of an electronic device is provided. The method is applied to the electronic equipment provided in any implementation manner of the first aspect. The control method of the electronic equipment comprises the following steps: the processor increases the magnetic field strength of the electromagnetic field formed by the coil to reduce the magnetic field strength of the electronically controlled magnetic attraction.

The coil forms an electromagnetic field when energized. In an embodiment of the application, the magnetic field direction of the electromagnetic field formed by the coil is opposite to the fixed magnetic field direction formed by the magnet.

For example, the processor controls the current value of the current on the coil to be equal to the first current value, and the coil forms a first electromagnetic field. The magnetic field strength of the first electromagnetic field (i.e., the first electromagnetic field strength) may be less than the magnetic field strength of the fixed magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the fixed magnet, the electric control magnetic attraction piece forms the magnetic field direction of the first superimposed magnetic field, which is the same as the magnetic field direction of the fixed magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the first superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the fixed magnetic field and the magnetic field intensity of the first electromagnetic field.

For another example, the processor controls the current value of the current on the coil to be equal to the second current value, and the coil forms a second electromagnetic field. The second current value may be greater than the first current value, and the magnetic field strength of the second electromagnetic field (i.e., the second electromagnetic field strength) may be greater than the magnetic field strength of the first electromagnetic field and less than the magnetic field strength of the fixed magnetic field.

In some possible implementations, the magnetic field strength of the second electromagnetic field may be less than the magnetic field strength of the fixed magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the fixed magnet, the electric control magnetic attraction piece forms the magnetic field direction of a second superimposed magnetic field, which is the same as the magnetic field direction of the fixed magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the fixed magnetic field and the magnetic field intensity of the second electromagnetic field.

In other possible implementations, the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the fixed magnetic field. Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the fixed magnet, the electric control magnetic attraction piece forms the magnetic field direction of a second superimposed magnetic field, which is the same as the magnetic field direction of the electromagnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the second electromagnetic field and the magnetic field intensity of the fixed magnetic field.

In this embodiment, the processor may control the magnetic field strength of the electromagnetic field formed by the coil by controlling the electric signal on the coil, so as to change the magnetic field strength of the superimposed magnetic field formed by superimposing the electromagnetic field and the fixed magnetic field (i.e. the magnetic field strength of the magnetic field formed by the electrically controlled magnetic attraction pieces), reduce the magnetic force of mutual attraction between the magnetic attraction pieces on two sides of the folding, and thus reduce the opening force required for unfolding the electronic device, so that the user can easily unfold the electronic device in a scenario where the user wants to unfold the folding device by one hand or wants to unfold the folding device in a more effort-saving manner.

Under the condition that the first magnetic attraction piece and the second magnetic attraction piece are electric control magnetic attraction pieces in the group of magnetic attraction pieces, the first magnetic attraction piece comprises a first magnet, and the second magnetic attraction piece comprises a second magnet. When the electronic equipment is in a folded state, the polarity setting orientation of the first magnet in the magnetic attraction piece is opposite to the polarity setting orientation of the second magnet. Illustratively, the N pole of the first magnet in the set of magnets is disposed away from the rotation mechanism, the S pole of the first magnet is disposed proximate to the rotation mechanism, the S pole of the second magnet is disposed away from the rotation mechanism 23, and the N pole of the second magnet is disposed proximate to the rotation mechanism. Thus, the N pole of the first magnet is opposite to the S pole of the second magnet and the S pole of the first magnet is opposite to the N pole of the second magnet.

In this way, the electronic equipment is in a folded state, the first magnetic attraction piece and the second magnetic attraction piece in the group of magnetic attraction pieces are mutually attracted, and the electronic equipment is kept in the folded state under the action of no external force.

In some examples, in order for the electronic device to remain in the collapsed state without external forces when the electronic device is in the collapsed state, the processor may control the coils on the two electronically controlled magnetic attraction members to be de-energized so that the first housing and the second housing may remain attracted by the attraction force between the first magnet and the second magnet.

In other examples, in order to reduce the attraction force of the electronic device in the folded state when the electronic device is in the folded state, the processor may control the coil of at least one of the two electrically controlled magnetic attraction members to be energized in a scene in which the electronic device is unfolded by a single hand by a user, thereby reducing the attraction force between the two electrically controlled magnetic attraction members and further reducing the attraction force between the first housing and the second housing.

Under the condition that the first magnetic attraction piece is an electric control magnetic attraction piece and the second magnetic attraction piece is a metal material capable of being attracted by magnetic force in the group of magnetic attraction pieces, the first magnetic attraction piece comprises a magnet, and the second magnetic attraction piece comprises a metal material. In the folded state of the electronic device, the polarity of the first magnet in the set of magnetic attraction pieces is opposite to the polarity of the metal material.

In some examples, in order for the electronic device to remain in the collapsed state without external forces when the electronic device is in the collapsed state, the processor may control the coils on the electronically controlled magnetic attraction to be de-energized so that the first housing and the second housing may remain attracted by the attractive force between the first magnet and the metallic material.

In other examples, in order to reduce the attraction force of the electronic device in the folded state when the electronic device is in the folded state, the processor may control the coil on the electronically controlled magnetic attraction member to be electrified in a scene in which the electronic device is unfolded by a single hand by a user, thereby reducing the attraction force between the electronically controlled magnetic attraction member and the metal material, and further reducing the attraction force between the first housing and the second housing.

The embodiment of the application provides a control method of electronic equipment, which reduces the opening force required by unfolding the electronic equipment by reducing the magnetic force of mutual attraction between magnetic attraction pieces at two sides of folding, so that a user can easily unfold the electronic equipment in a scene of needing single-hand unfolding or needing to unfold the folding equipment in a labor-saving mode.

In some possible implementations of the second aspect, the electronic device further includes an inductor. A processor increases the magnetic field strength of an electromagnetic field formed by the coil, comprising: the sensor outputs a trigger signal in response to a trigger operation. The processor increases the magnetic field strength of the electromagnetic field formed by the coil in response to the trigger signal.

In some possible implementations of the second aspect, the trigger operation includes at least a first trigger sub-operation and a second trigger sub-operation. The sensor outputting a trigger signal in response to a trigger operation, comprising: the sensor outputs a first trigger sub-signal in response to the first trigger sub-operation. Alternatively, the sensor outputs a second trigger sub-signal in response to the second trigger sub-operation.

The trigger operation includes at least a first trigger sub-operation and a second trigger sub-operation. The first trigger sub-operation may be a click operation on the screen, and the second trigger sub-operation may be a long press operation on the screen. It should be appreciated that any two operations that can be distinguished by the sensor can be used as a first trigger sub-operation and a second trigger sub-operation, respectively.

In some possible implementations of the second aspect, the processor increases a magnetic field strength of an electromagnetic field formed by the coil in response to the trigger signal, including: the processor is responsive to the first trigger signal to increase the current value of the current on the coil to a first current value to increase the magnetic field strength of the electromagnetic field formed by the coil to a first electromagnetic field strength. Alternatively, the processor increases the current value of the current on the coil to a second current value in response to the second trigger signal to increase the magnetic field strength of the electromagnetic field formed by the coil to a second electromagnetic field strength. The first current value is smaller than the second current value, and the first electromagnetic field strength is smaller than the second electromagnetic field strength.

It can be understood that the first current value is smaller than the second current value, and the first electromagnetic field strength is smaller than the second electromagnetic field strength, so that the first superimposed magnetic field strength formed by the electric control magnetic attraction piece when the coil is the first current value is larger than the second superimposed magnetic field strength formed by the electric control magnetic attraction piece when the coil is the second current value.

For example, in a scenario where a user with small finger strength, such as a woman or a student, wants to spread out the electronic device with less effort, the user may continuously press the key three times to input the first trigger operation to the electronic device. After the electronic equipment senses the first trigger operation, the processor can control the current value of the coil on each electric control magnetic attraction piece to be equal to the first current value. Thus, the magnetic field intensity of the magnetic field formed by each electric control magnetic attraction piece is reduced, so that attraction force formed between the two electric control magnetic attraction pieces is reduced.

For example, in a scenario where a user with a large finger force, such as a man or an athlete, wants to develop the electronic device with less effort, the user may input the first trigger operation to the electronic device by pressing the auxiliary screen for a long time, even though the user wants to develop the electronic device with less effort. After the electronic equipment senses the first trigger operation, the processor can control the current value of the coil on the electric control magnetic attraction piece to be increased from 0 to be equal to the first current value. Therefore, the magnetic field intensity of the magnetic field formed by the electric control magnetic attraction piece is reduced, so that the attraction force formed between the electric control magnetic attraction piece and the metal material is reduced, and meanwhile, a certain attraction force is reserved, so that a certain damping sense is realized in the unfolding process.

Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the magnet, the electric control magnetic attraction piece forms the magnetic field direction of the first superimposed magnetic field, which is the same as the magnetic field direction of the fixed magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the first superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the fixed magnetic field and the magnetic field intensity of the first electromagnetic field.

For example, in a scenario where a user with smaller finger strength, such as an elderly person, wants to develop the electronic device with less effort, the user may press the start key to input a second trigger operation to the electronic device. After the electronic device senses the second trigger operation, the processor can control the current value of the coil on each electric control magnetic attraction piece to be increased from 0 to be equal to the second current value. The second current value may be greater than the first current value, and thus the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the first electromagnetic field. The magnetic field strength of the second electromagnetic field may be smaller than the magnetic field strength of the fixed magnetic field.

Because the magnetic field direction of the electromagnetic field formed by the coil is opposite to the magnetic field direction of the magnet, the electric control magnetic attraction piece forms the magnetic field direction of a second superimposed magnetic field, which is the same as the magnetic field direction of the fixed magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the fixed magnetic field and the magnetic field intensity of the second electromagnetic field. Wherein the magnetic field strength of the second superimposed magnetic field is smaller than the magnetic field strength of the first superimposed magnetic field.

Therefore, the magnetic field intensity of the superimposed magnetic field formed by each electric control magnetic attraction piece is reduced to different degrees, so that attraction force formed between two electric control magnetic attraction pieces in a group of magnetic attraction pieces is reduced to different degrees, and various attraction forces can be formed between the first shell and the second shell.

According to the electronic equipment, a plurality of trigger operations can be set according to actual requirements of different scenes, and different opening forces of the electronic equipment are set for each trigger operation. Therefore, a user can select input triggering operation according to the actual demand of the user, the opening force of the electronic equipment which the user wants is obtained, and the suitability of the electronic equipment for different user groups is improved.

In some possible implementations of the second aspect, one of the first and second magnetic attraction pieces includes an electrically controlled magnetic attraction piece. When the current value of the coil current reaches the second current value, the magnetic field strength of the electromagnetic field formed by the coil is larger than or equal to the magnetic field strength of the fixed magnetic field.

In some examples, when the electronic device is in a folded state, the processor may control the coil on the electronically controlled magnetic attraction member to be energized, so that the electronically controlled magnetic attraction member forms a magnetic field with a polarity opposite to that of the magnet, thereby forming a repulsive force between the electronically controlled magnetic attraction member and the metal material, and further forming a repulsive force between the first housing and the second housing.

For example, there are substances such as water, sweat, oil, glue, etc. on the hands of users, which are inconvenient to spread the electronic device with fingers, and there is a need to spread the electronic device. The user may input a second trigger sub-operation to the electronic device through a gesture operation that does not contact the electronic device. After the electronic equipment senses the operation of the second trigger, the processor can control the current value of the coil on the electric control magnetic attraction piece to be equal to a second current value.

Because the electromagnetic field formed after the coil of the electric control magnetic attraction piece is electrified is opposite to the fixed magnetic field formed by the magnet, the magnetic field direction of the second superimposed magnetic field intensity of the electric control magnetic attraction piece is opposite to the magnetic field direction of the fixed magnetic field, and the second superimposed magnetic field intensity of the electric control magnetic attraction piece is the difference value between the magnetic field intensity of the second electromagnetic field and the magnetic field intensity of the fixed magnetic field.

Thus, the electric control magnetic attraction piece forms a magnetic field with the polarity opposite to that of the magnet, so that repulsive force between the electric control magnetic attraction piece and the metal material is formed, repulsive force between the first shell and the second shell is further formed, and automatic unfolding of the electronic equipment is realized.

In some possible implementations of the second aspect, the electronic device further includes an ambient light sensor. The control method of the electronic device further comprises the following steps: the processor obtains ambient light intensity of the ambient light sensor collection electronic device. A processor increases the magnetic field strength of an electromagnetic field formed by the coil, comprising: the processor increases the magnetic field strength of the electromagnetic field formed by the coil in the event that the ambient light level is greater than a preset brightness threshold.

The processor starts the false touch prevention function, the electronic equipment is in the false touch prevention state, and under the condition that the processor acquires a trigger signal, the processor can not adjust the electric signal of the coil in the electric control magnetic attraction piece, so that attraction force between the first magnetic attraction piece and the second magnetic attraction piece cannot be changed.

In a third aspect, a computer-readable storage medium is provided. The computer readable storage medium comprises computer instructions which, when run on a processor, cause the processor to perform the method according to any one of the implementations of the second aspect.

It will be appreciated that any of the above-mentioned computer readable storage media may be implemented by or associated with the control method of the corresponding electronic device provided above, and thus, the benefits achieved by the above-mentioned computer readable storage media may refer to the benefits in the control method of the corresponding electronic device provided above, and will not be repeated herein.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.

Hereinafter, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Furthermore, in the present application, directional terms "upper", "lower", etc. are defined with respect to the orientation in which the components are schematically disposed in the drawings, and it should be understood that these directional terms are relative concepts, which are used for description and clarity with respect thereto, and which may be changed accordingly in accordance with the change in the orientation in which the components are disposed in the drawings.

The application provides an electronic device, which is a foldable electronic device. Foldable electronic devices may include various electronic devices that have a flexible screen and that can change the flexible screen and its own unfolded state or folded state. Under different use demands, the foldable electronic equipment can be unfolded to an unfolding state, can be folded to a folding state and can be in an intermediate hovering state between the unfolding state and the folding state, namely, the intermediate hovering state is positioned on a switching path of the electronic equipment between the folding state and the unfolding state. Thus, a foldable electronic device has at least two states, an unfolded state and a folded state. In some cases, a third state, an intermediate hover state between the expanded state and the collapsed state, may also be further included. It will be appreciated that the intermediate hover state is not the only state, but may be any one or more states of a switching path of the electronic device between an expanded state and a collapsed state.

FIG. 1 is a schematic diagram of a graph of an opening force of an electronic device at different deployment angles; FIG. 2 is a side view of the electronic device corresponding to point A in FIG. 1 shown in an expanded state; FIG. 3 is a side view of the electronic device corresponding to point B of FIG. 1 shown in an expanded state; FIG. 4 is a side view of the electronic device corresponding to point C in FIG. 1 shown in an expanded state; fig. 5 is a schematic view of a scenario in which a user deploys an electronic device with one hand.

At present, in order to ensure folding stability of the electronic equipment in a folded state, magnetic attraction pieces are arranged on two sides of the folding electronic equipment. The folding stability of the electronic equipment is improved through the magnetic force of mutual attraction between the magnetic attraction pieces at the two folding sides. The opening forces required by the electronic device at different angles of deployment can be seen in fig. 1.

It should be noted that, the opening force required by the electronic device mentioned herein is the force for the user to open the electronic device. The opening force needs to overcome the rotating friction force provided by the mechanical rotating shaft and the magnetic force of mutual attraction between the parts at the two sides of the folding.

In fig. 1, the abscissa indicates the expansion angle α of the electronic device, and the ordinate indicates the opening force F required for the electronic device. As can be seen from fig. 1, in the stage of opening the electronic device, when the angle of opening the electronic device is low, the opening force required for opening the electronic device is large. As the angle of deployment increases, the opening force required to deploy the electronic device decreases until the electronic device is fully deployed. The unfolding angle of the electronic equipment refers to an included angle formed between two parts of the electronic equipment, which are folded in a rotating way.

When the unfolding angle of the electronic equipment is low, the electronic equipment is difficult to unfold due to the fact that the opening force required for unfolding the electronic equipment is large, and under the scene that a user wants to unfold the folding equipment by one hand or wants to unfold the folding equipment in a labor-saving mode, the force is small.

Based on this, the embodiment of the application provides an electronic device and a control method thereof, so as to overcome the problem that the electronic device is difficult to develop at present. The embodiment of the application provides a control method of electronic equipment, which reduces the opening force required by unfolding the electronic equipment by reducing the magnetic force of mutual attraction between magnetic attraction pieces at two sides of folding, so that a user can easily unfold the electronic equipment in a scene of needing single-hand unfolding or needing to unfold the folding equipment in a labor-saving mode.

Referring to fig. 6, fig. 6 is a schematic structural diagram of an electronic device according to some embodiments of the present application. The electronic device 100 may comprise a flexible screen 10 and a folding means 20. Wherein the flexible screen 10 may be a touch screen. It is to be understood that fig. 6 only schematically illustrates some components included in the electronic device 100, and the actual shape, actual size, actual position, and actual configuration of these components are not limited by fig. 6.

The flexible screen 10 can be used to display information and provide an interactive interface for a user. In various embodiments of the present application, the flexible screen 10 may be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini light-emitting diode (mini light-emitting diode) display screen, a micro light-emitting diode (micro organic light-emitting diode) display screen, a micro organic light-emitting diode (micro organic light-emitting diode) display screen, a quantum dot light-emitting diode (quantum dot light emitting diode, QLED) display screen, or the like.

The flexible screen 10 is switchable between an extended state and a collapsed state. The flexible screen 10 comprises a first portion 11, a second portion 12 and a third portion 13, the third portion 13 being located between the first portion 11 and the second portion 12. At least a third portion 13 of the flexible screen 10 is made of a flexible material. It will be appreciated that the third portion 13 is made of a flexible material; the first portion 11 and the second portion 12 may be made of a flexible material, may be made of a rigid material, and may be made of a flexible material, which is not limited herein.

As shown in fig. 6, when the flexible screen 10 is in the unfolded state, the first portion 11, the second portion 12 and the third portion 13 are disposed coplanar and facing the same. In this state, can realize the large-scale display, can provide richer information for the user, bring better use experience for the user.

Referring to fig. 7, fig. 7 is a schematic structural diagram of an electronic device 100 in a folded state according to an embodiment of the application. When the flexible screen 10 is in the folded state, the third portion 13 (not shown in fig. 3) is in the folded state, and the first portion 11 (not shown in fig. 3) is opposite the second portion 12 (not shown in fig. 3). In this state, the flexible screen 10 is invisible to the user, and the folding device 20 is protected outside the flexible screen 10 to prevent the flexible screen 10 from being scratched by hard objects. Meanwhile, in this state, the volume of the foldable electronic device 100 can be reduced, facilitating the storage of the foldable electronic device 100.

As shown in fig. 7, the electronic device 100 may also include an auxiliary screen 30. The auxiliary screen 30 may be displayed toward the user in the collapsed state of the electronic device 100 to help the user understand time, calendar, etc. The auxiliary screen 30 may be a rigid screen or a flexible screen, which is not limited by the present application. In some examples, the auxiliary screen 30 may be a touch display screen.

The folding device 20 is used to support the flexible screen 10 and allow the flexible screen 10 to switch between an unfolded state and a folded state. Referring to fig. 8 and 9, fig. 8 is a schematic structural view of the folding apparatus 20 in the electronic device 100 shown in fig. 6, and fig. 9 is a schematic structural view of the folding apparatus 20 in the electronic device 100 shown in fig. 7. In the present embodiment, the folding device 20 includes a first housing 21, a second housing 22, and a rotation mechanism 23. It will be appreciated that fig. 8 and 9 only schematically illustrate some of the components comprised by the folding device 20, the actual shape, actual size, actual position and actual configuration of which are not limited by fig. 8 and 9.

The folding device 20 has a support surface that can be used to support the flexible screen 10. By the support of the support surface, in the unfolded state, the flexible screen 10 can be made flat, and the display surface of the flexible screen 10 can be made flat.

The first housing 21 is used to secure and support the first portion 11 of the flexible screen 10 of fig. 6. Specifically, the first housing 21 has a support surface, and the first housing 21 is fixed by the support surface and supports the first portion 11 of the flexible screen 10 in fig. 6. Exemplary connection of the support surface to the first portion 11 includes, but is not limited to, gluing.

The second housing 22 is used to secure and support the second portion 12 of the flexible screen 10 of fig. 6. Specifically, the second housing 22 has a support surface by which the second housing 22 is secured and supports the second portion 12 of the flexible screen 10 of fig. 6. Exemplary connection of the support surface to the second portion 11 includes, but is not limited to, gluing.

The first housing 21 and/or the second housing 22 may respectively form a mounting space for mounting electronic components such as a circuit board, a battery, and the like of the electronic apparatus 100. The first housing 21 and the second housing 22 may be of equal thickness or of different thickness, and the embodiment of the application is not limited thereto.

In some embodiments, the first housing 21 and the second housing 22 may both have an installation space, and the electronic components of the electronic device 100 described above are distributed in the two side housings. In other embodiments, only the first housing 21 may be provided with an installation space, and the electronic components of the electronic apparatus 100 may be intensively distributed in the first housing 21; alternatively, both the first housing 21 and the second housing 22 may be provided with mounting spaces, but most of the components of the electronic device 100 are disposed in the second housing 22, and the other part is disposed in the first housing 21, so that the first housing 21 is lighter and more convenient to fold and unfold.

The first housing 21 may be a single structural unit or may be assembled from multiple parts. Similarly, the second housing 22 may be a unitary structure or may be formed from multiple parts assembled together.

The rotation mechanism 23 is used to support the third portion 13 of the flexible screen 10. Illustratively, a rotation mechanism 23 is located between the first housing 21 and the second housing 22, the rotation mechanism 23 being connected to the first housing 21 and the second housing 22, respectively, the first housing 21 and the second housing 22 being rotatably connected by the rotation mechanism 23, thereby effecting relative rotation between the first housing 21 and the second housing 22. Specifically, as shown in fig. 8, the rotation axis of the first casing 21 with respect to the second casing 22 extends in the width direction of the electronic apparatus 100.

With continued reference to fig. 8, the first housing 21 may include a first magnetic member CX1, and the second housing 22 may include a second magnetic member CX2, and when the folding device 20 is in the folded state, the first magnetic member CX1 and the second magnetic member CX2 are attracted to each other, so that the folding device 20 remains in the folded state without an external force.

The number of the first magnetic attraction pieces CX1 may be one or a plurality. In the case where the number of the first magnetic members CX1 is plural, the plural first magnetic members CX1 may be uniformly disposed at different positions of the first housing 21. The number of the second magnetic attraction pieces CX2 may be one or more. In the case where the number of the second magnetic members CX2 is plural, the plural second magnetic members CX2 may be provided at different positions of the second housing 22.

The first magnetic attraction CX1 is located on the non-display side of the first portion 11 of the flexible screen 10. It will be appreciated that the first magnetic part CX1 may be located in the installation space of the first housing 21. The second magnetic part CX2 is located on the non-display side of the second portion 12 of the flexible screen 10. It will be appreciated that the second magnetic part CX2 may be located in the installation space of the second housing 22.

In some examples, the first magnetic part CX1 may be located at an edge position of the first housing 21, and the second magnetic part CX2 may also be located at an edge position of the second housing 22.

Illustratively, the first magnetic part CX1 may be located at an edge of the first housing 21 remote from the rotation mechanism 23. For example, two first magnetic attraction pieces CX1 are located at both ends of the edge of the first housing 21 remote from the rotation mechanism 23. The second magnetic part CX2 may be located at the edge of the second housing 22 remote from the rotation mechanism 23. For example, two second magnetic attraction pieces CX2 are located at both ends of the edge of the second housing 22 remote from the rotation mechanism 23.

Wherein, the first magnetic part CX1 is located at the edge of the first housing 21, and the second magnetic part CX2 may be located at the edge of the second housing 22 away from the rotation mechanism 23. This can better ensure the engaging effect of the edge positions of the first housing 21 and the second housing 22 when the electronic apparatus 100 is in the folded state, thereby preventing the electronic apparatus 100 from being easily unfolded.

In some examples, the plurality of first magnetic attractors CX1 and the plurality of second magnetic attractors CX2 may be connected to each other by a metal trace.

The number of the first magnetic attraction pieces CX1 and the second magnetic attraction pieces CX2 may be equal or different. When the number of the first magnetic members CX1 and the second magnetic members CX2 is equal, the positions of the plurality of first magnetic members CX1 on the first housing 21 and the positions of the plurality of second magnetic members CX2 on the first housing 21 are in one-to-one correspondence. The position on the first housing 21 corresponds to the position on the second housing 22, and it is understood that the position on the first housing 21 is opposite to the position on the second housing 22 when the electronic device 100 is in the folded state. The one first magnetic member CX1 and the one second magnetic member CX2 at positions on the first housing 21 and the second housing 22 corresponding to the positions thereof are hereinafter referred to as a group of magnetic members.

The first magnetic part CX1 and the second magnetic part CX2 of the group of magnetic parts may have the same shape or may have different shapes. For example, the shape of the first magnetic part CX1 and the shape of the second magnetic part CX2 in the group of magnetic parts are both bar-shaped.

At least one of the first magnetic part CX1 and the second magnetic part CX2 in the group of magnetic parts is an electric control magnetic part. The electric control magnetic attraction piece refers to a structure capable of changing the intensity of a magnetic field formed by a substance through an electric signal (such as current and voltage).

Referring to fig. 10, fig. 10 is a schematic diagram illustrating a structure of an electrically controlled magnetic attraction member according to some embodiments of the application. The electronically controlled magnetic attraction 40 may include a magnet 41 and a coil 42. The coil 42 may be wound around the magnet 41.

The permanent magnet 41 may include a permanent magnet, such as a magnet. The magnets may be in the shape of a bar magnet, a cylindrical magnet, or the like, and the embodiment of the present application is not limited thereto. For easy understanding, the permanent magnets are used as the magnets, the fixed magnetic field formed by the magnets is a permanent magnetic field formed by the magnets, and the permanent magnets are used as bar magnets for illustration.

Referring to fig. 11, fig. 11 shows a permanent magnetic field formed by the permanent magnets. The permanent magnet 41 forms a permanent magnetic field due to its own characteristics, and magnetic lines of force of the permanent magnetic field are directed from the N pole to the S pole outside the permanent magnet.

The coil 42 may comprise a relatively conductive metallic material such as copper, tungsten, silver, or the like. The coil 42 may be wound around the permanent magnet 41 in one direction by a plurality of turns as shown in fig. 10. The number of turns of the coil 42 around the magnet may be 5, 20, 50, 100, or the like. In practice, the number of turns of the coil 42 around which the magnet is wound may depend on factors such as the thickness of the coil 42, the distance between adjacent turns, the length of the magnet, etc., and embodiments of the present application are not limited in this regard.

When the coil 42 is energized, the coil 42 forms an electromagnetic field. Referring to fig. 12, fig. 12 illustrates the electromagnetic field formed after the coil is energized. In the embodiment of the present application, the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet. Thus, by controlling the magnitude of the current on the coil 42, the magnetic field strength of the electromagnetic field can be controlled to adjust the degree of weakening of the permanent magnetic field by the electromagnetic field, so that the magnetic field strength of the electric control magnetic attraction piece can be conveniently reduced.

Fig. 13 is a schematic structural diagram of an electronic device according to some embodiments of the present application.

As shown in fig. 13, in addition to the electronic device 100 including a display screen (the display screen includes the flexible screen 10 and the auxiliary screen 30 described above), the electronic device 100 may further include electronic components such as a processor 110, an ambient light sensor 120, keys 130, a camera 140, an audio module 150, a microphone 160, and a wireless communication module (not shown in fig. 13).

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Repeated accesses are avoided and the latency of the processor 110 is reduced, thereby improving the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The interfaces may include an integrated circuit (inter-integrated circuit, I2C) interface, an integrated circuit built-in audio (inter-integrated circuit sound, I2S) interface, a pulse code modulation (pulse code modulation, PCM) interface, a universal asynchronous receiver transmitter (universal asynchronous receiver/transmitter, UART) interface, a mobile industry processor interface (mobile industry processor interface, MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (subscriber identity module, SIM) interface, and/or a universal serial bus (universal serial bus, USB) interface, among others.

In some embodiments, the processor 110 may contain multiple sets of I2C buses. The processor 110 may be coupled to the ambient light sensor 120, etc., respectively, through different I2C bus interfaces. For example: the processor 110 may be coupled to the ambient light sensor 120 through an I2C interface, such that the processor 110 communicates with the ambient light sensor 120 through an I2C bus interface to implement an ambient light level detection function of the electronic device 100.

The I2S interface may be used for audio communication. In some embodiments, the processor 110 may contain multiple sets of I2S buses. The processor 110 may be coupled to the audio module via an I2S bus to enable communication between the processor 110 and the audio module 150.

PCM interfaces may also be used for audio communication to sample, quantize and encode analog signals. In some embodiments, the audio module 150 and the wireless communication module may be coupled through a PCM bus interface. In some embodiments, the audio module 150 may also transmit audio signals to the wireless communication module through the PCM interface to implement a function of answering a call through the bluetooth headset. Both the I2S interface and the PCM interface may be used for audio communication.

The UART interface is a universal serial data bus for asynchronous communications. The bus may be a bi-directional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, a UART interface is typically used to connect the processor 110 with the wireless communication module. For example: the processor 110 communicates with a bluetooth module in the wireless communication module through a UART interface to implement a bluetooth function. In some embodiments, the audio module 150 may transmit an audio signal to the wireless communication module through a UART interface, so as to implement a function of playing music through a bluetooth headset.

The MIPI interface may be used to connect the processor 110 to peripheral devices such as the flexible screen 10, the camera 140, and the like. The MIPI interfaces include camera serial interfaces (camera serial interface, CSI), display serial interfaces (display serial interface, DSI), and the like. In some embodiments, processor 110 and camera 140 communicate through a CSI interface to implement the photographing function of electronic device 100. The processor 110 communicates with the flexible screen 10 via a DSI interface to implement the display functionality of the electronic device 100.

The GPIO interface may be configured by software. The GPIO interface may be configured as a control signal or as a data signal. In some embodiments, a GPIO interface may be used to connect the processor 110 with the camera 140, the flexible screen 10, the wireless communication module, the audio module 150, the ambient light sensor 120, and the like. The GPIO interface may also be configured as an I2C interface, an I2S interface, a UART interface, an MIPI interface, etc.

The USB interface is an interface conforming to the USB standard specification, and can be specifically a Mini USB interface, a Micro USB interface, a USB Type C interface and the like. The USB interface may be used to connect a charger to charge the electronic device 100, or may be used to transfer data between the electronic device 100 and a peripheral device. And can also be used for connecting with a headset, and playing audio through the headset. The interface may also be used to connect other electronic devices, such as AR devices, etc.

It should be understood that the interfacing relationship between the modules illustrated in the embodiments of the present application is only illustrative, and is not meant to limit the structure of the electronic device 100. In other embodiments of the present application, the electronic device 100 may also employ different interfacing manners in the above embodiments, or a combination of multiple interfacing manners.

The camera 140 may be used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, the electronic device 100 may include 1 or N cameras 140, N being a positive integer greater than 1.

A microphone 160, also called a "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or transmitting voice information, a user can sound near the microphone through the mouth, inputting a sound signal to the microphone. The electronic device 100 may be provided with at least one microphone. In other embodiments, the electronic device 100 may be provided with two microphones, and may implement a noise reduction function in addition to collecting sound signals. In other embodiments, the electronic device 100 may also be provided with three, four, or more microphones to enable collection of sound signals, noise reduction, identification of sound sources, directional recording functions, etc.

The ambient light sensor 120 is used to sense ambient light level. The electronic device 100 may adaptively adjust the light emitting brightness of the flexible screen according to the perceived ambient light level. The ambient light sensor 120 may also be used to automatically adjust white balance during photographing. The ambient light sensor 120 may also detect whether the electronic device 100 is in a pocket to prevent false touches. For example, ambient light sensor 120 may collect ambient light level of an environment in which electronic device 100 is located and provide the ambient light level to processor 110.

The keys 130 include a power-on key, a volume key, etc. Key 130 may also include an on key dedicated to reducing the on force of electronic device 100. The keys 130 may be mechanical keys, capacitive keys, pressure sensitive keys, or other suitable keys. The electronic device 100 may receive key inputs, generating key signal inputs related to user settings and function controls of the electronic device 100. The keys may be coupled to the processor 110 such that a user, by pressing the keys, can cause the keys 130 to provide corresponding signals to the processor 110.

At least one of the keys 130, microphone 160, flexible screen 10, camera 140 shown in fig. 13 may serve as a sensor for sensing a triggering operation of the electronic device 100. The sensor generates a trigger signal by sensing a trigger operation, and provides the trigger signal to the processor 110.

For example, the electronic device 100 may trigger operations through key sensing, and the corresponding trigger operations may be key operations such as double-clicking volume keys, clicking trigger keys, and the like. Also, for example, the electronic device may sense a triggering operation through the camera, and the corresponding triggering operation may be a gesture operation set by the user, a facial expression set by the user, or another suitable action. As another example, the electronic device may sense a triggering operation through the auxiliary screen shown in fig. 7, and the corresponding triggering operation may be a touch operation such as a screen sliding track, a screen clicking operation, or the like set by the user. Further, for example, the electronic device may sense a triggering operation through the microphone, and the corresponding triggering operation may be a voice command set by the user or a suitable sound command.

The processor 110 in the electronic device 100 may also be coupled to the coil 42 of the electronically controlled magnetic attraction 40. When the processor 110 obtains the trigger signal, the processor 110 can adjust the electrical signal of the coil 42 in the electric control magnetic attraction piece 40 to control the coil 42 to be electrified to form an electromagnetic field, so as to change the magnetic field formed by the electric control magnetic attraction piece 40, reduce the attraction force between the first magnetic attraction piece CX1 and the second magnetic attraction piece CX2, and facilitate the user to expand the electronic device 100.

Referring to fig. 14, fig. 14 is a schematic structural diagram of a folding device in an electronic apparatus. The electronic device 100 may further include a flexible circuit board (flexible printed circuit, abbreviated as FPC) 50. The flexible circuit board 50 may include a first board section 51, a second board section 52, and a third board section 53, wherein the third board section 53 may be located between the first board section 51 and the second board section 52 and connected to the first board section 51 and the second board section 52, respectively. The first plate section 51 may be located in the installation space of the first housing 21, the second plate section 52 may be located in the installation space of the second housing 22, and the third plate section 53 may be fitted to the rotation mechanism 23. Because of the flexible circuit board 50 having a bendable property, the third plate section 53 can fit the rotation mechanism 23 and fold or unfold together with the rotation mechanism 23. In this way, one flexible circuit board 50 can be in both the installation space of the first housing 21 and the installation space of the second housing 22.

In this way, in the case where some of the above-described electronic components (for example, the processor 110, the camera 140, etc.) are located in the installation space of the first housing 21, and other electronic components (for example, the microphone 160, the on key, etc.) are located in the installation space of the second housing 22, the FPC50 may be used to transmit signals across the housings, enabling signal transmission between the electronic components in the first housing 21 and the electronic components in the second housing 22.

In addition, the electronic device may also include some metal traces 60. The metal traces 60 are bendable, so that the metal traces may also transmit signals across the housing. Illustratively, the first magnetic part CX1 located in the first housing 21 and the second magnetic part CX2 located in the second housing 22 may be connected by a metal trace 60. Also by way of example, some of the keys located in the second housing 22 and the processor located in the first housing 21 may be connected by metal traces 60.

For ease of understanding, the following description will be given by taking the example of the processor 110 controlling the strength of the electromagnetic field by controlling the current on the coil 42.

In some examples, the processor 110 may control the coil 42 to be de-energized. In the case where the coil 42 is not energized, the magnetic field formed by the electronically controlled magnetic attraction 40 may be a permanent magnetic field formed by a magnet, as shown in fig. 15.

In other examples, the processor 110 may control the energizing of the coil 42. In the case of the energizing of the coil 42, the magnetic field formed by the electronically controlled magnetic attraction 40 may be a superimposed magnetic field between the permanent magnetic field formed by the magnet and the electromagnetic field formed by the coil 42, since the coil 42 will form an electromagnetic field.

For example, the processor 110 controls the current value of the current on the coil 42 to be equal to the first current value, and the coil 42 forms a first electromagnetic field. The magnetic field strength of the first electromagnetic field may be less than the magnetic field strength of the permanent magnetic field. Since the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet 41, the electric control magnetic attraction piece 40 forms the magnetic field direction of the first superimposed magnetic field, which is the same as the magnetic field direction of the permanent magnet; and, the electronically controlled magnetic attraction member 40 forms a first superimposed magnetic field having a magnetic field strength equal to the difference between the magnetic field strength of the permanent magnetic field and the magnetic field strength of the first electromagnetic field.

For another example, the processor 110 controls the current value of the current on the coil 42 to be equal to the second current value, and the coil 42 forms a second electromagnetic field. The second current value may be greater than the first current value, and thus the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the first electromagnetic field. The magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the permanent magnetic field.

In some possible implementations, the magnetic field strength of the second electromagnetic field may be less than the magnetic field strength of the permanent magnetic field. Since the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet, the electronically controlled magnetic attraction member 40 forms a second superimposed magnetic field having the same magnetic field direction as the permanent magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the permanent magnetic field and the magnetic field intensity of the second electromagnetic field.

In other possible implementations, the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the permanent magnetic field. Since the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet, as shown in fig. 16, the electronically controlled magnetic attraction member 40 forms the magnetic field direction of the second superimposed magnetic field, which is the same as the magnetic field direction of the electromagnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the second electromagnetic field and the magnetic field intensity of the permanent magnetic field. It will be appreciated that where the processor 110 controls the current value of the current on the coil 42 to be equal to the second current value, the electronically controlled magnetic attraction element 40 has a magnetic property opposite to that of the permanent magnet.

The first magnetic part CX1 of the group of magnetic parts may be an electrically controlled magnetic part, and the second magnetic part CX2 of the group of magnetic parts may be a metal material capable of being magnetically attracted (the metal material may include a metal or an alloy of elements such as iron, cobalt, and nickel). Alternatively, the first magnetic part CX1 of the group of magnetic parts may be a metal material capable of being magnetically attracted, and the second magnetic part CX2 of the group of magnetic parts may be an electrically controlled magnetic part. Alternatively, the first magnetic part CX1 and the second magnetic part CX2 of the group of magnetic parts may be electrically controlled magnetic parts.

In addition, in the case where one of the first magnetic part CX1 and the second magnetic part CX2 is a magnet and the other of the first magnetic part CX1 and the second magnetic part CX2 is a metal material that can be attracted by the magnet, all of the first magnetic parts CX1 in the first casing 21 may be electrically controlled magnetic parts, and all of the second magnetic parts CX2 in the second casing 22 may be metal materials that can be attracted by magnetic forces; all the first magnetic attraction pieces CX1 in the first casing 21 may be made of a metal material that can be magnetically attracted, and all the second magnetic attraction pieces CX2 in the second casing 22 may be electrically controlled magnetic attraction pieces; the first magnetic part CX1 of the first housing 21 may be an electrically controlled magnetic part, the second magnetic part CX1 of the second housing 22 may be a metal material that can be magnetically attracted, and the second magnetic part CX2 of the first housing 22 may be an electrically controlled magnetic part.

Under the condition that the first magnetic part CX1 and the second magnetic part CX2 in the group of magnetic parts are electrically controlled magnetic parts, the first magnetic part CX1 comprises a first magnet, and the second magnetic part CX2 comprises a second magnet. In the folded state of the electronic device 100, the polarity setting orientation of the first magnet and the polarity setting orientation of the second magnet in the set of magnetic attraction members are opposite. Illustratively, the N pole of the first magnet in a set of magnets is disposed away from the rotation mechanism 23, the S pole of the first magnet is disposed proximate to the rotation mechanism 23, the S pole of the second magnet is disposed away from the rotation mechanism 23, and the N pole of the second magnet is disposed proximate to the rotation mechanism 23. Thus, the N pole of the first magnet is opposite to the S pole of the second magnet and the S pole of the first magnet is opposite to the N pole of the second magnet.

In this way, in the folded state of the electronic apparatus 100, the first magnetic part CX1 and the second magnetic part CX2 of the group of magnetic parts attract each other, and the electronic apparatus 100 is kept in the folded state without an external force.

In some examples, in order for the electronic device 100 to remain in the folded state without external force while the electronic device 100 is in the folded state, the processor 110 may control the coils 42 on the two electronically controlled magnetic attraction members to be de-energized, thereby allowing the first housing 21 and the second housing 22 to remain attracted by the attraction force between the first magnet and the second magnet, as shown in fig. 17.

In other examples, in order to reduce the attraction force of the electronic device 100 in the folded state when the electronic device 100 is in the folded state, the processor 110 may control the coil 42 of at least one of the two electrically controlled magnetic attraction members to be energized in a scene in which the electronic device 100 is unfolded by a single hand of a user, so as to reduce the attraction force between the two electrically controlled magnetic attraction members, and thus reduce the attraction force between the first housing 21 and the second housing 22.

The trigger operation may include a first trigger sub-operation and a second trigger sub-operation. It will be appreciated that the first trigger sub-operation and the second trigger sub-operation are two different trigger operations.

For example, in a scenario where a user with small finger strength, such as a woman or a student, wants to develop the electronic device 100 with less effort, the user may continuously press the key three times to input the first trigger operation to the electronic device 100. After the electronic device 100 senses the first trigger operation, the processor 110 may control the current value of the coil 42 on each electronically controlled magnet to increase from 0 to equal the first current value. Thus, the magnetic field intensity of the magnetic field formed by each electric control magnetic attraction piece is reduced, so that attraction force formed between the two electric control magnetic attraction pieces is reduced.

Since the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet, the electronically controlled magnetic attraction member 40 forms a first superimposed magnetic field having the same magnetic field direction as the permanent magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the first superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the permanent magnetic field and the magnetic field intensity of the first electromagnetic field.

For another example, in a scenario where a user with smaller finger strength, such as an elderly person, wants to develop the electronic device 100 with less effort, the user may press the start key to input a second trigger operation to the electronic device 100. After the electronic device 100 senses the second trigger operation, the processor 110 may control the current value of the coil 42 on each electronically controlled magnetic attraction to increase from 0 to equal to the second current value. The second current value may be greater than the first current value, and thus the magnetic field strength of the second electromagnetic field may be greater than the magnetic field strength of the first electromagnetic field. The magnetic field strength of the second electromagnetic field may be less than the magnetic field strength of the permanent magnetic field.

Since the magnetic field direction of the electromagnetic field formed by the coil 42 is opposite to the magnetic field direction of the permanent magnet, the electronically controlled magnetic attraction member 40 forms a second superimposed magnetic field having the same magnetic field direction as the permanent magnetic field; and the electric control magnetic attraction piece forms the magnetic field intensity of the second superimposed magnetic field, which is equal to the difference value between the magnetic field intensity of the permanent magnetic field and the magnetic field intensity of the second electromagnetic field. Wherein the magnetic field strength of the second superimposed magnetic field is smaller than the magnetic field strength of the first superimposed magnetic field.

In the case that the first magnetic part CX1 is an electrically controlled magnetic part and the second magnetic part CX2 is a metal material that can be magnetically attracted in a set of magnetic parts, the first magnetic part CX1 includes a magnet and the second magnetic part CX2 includes a metal material. In the folded state of the electronic device 100, the polarity of the first magnet in the set of magnetic attraction members is opposite to the polarity of the metallic material.

In some examples, in order for the electronic device 100 to remain in the folded state without external force while the electronic device 100 is in the folded state, the processor 110 may control the coil 42 on the electronically controlled magnetic attraction to be de-energized, such that the first housing 21 and the second housing 22 may remain attracted by the attraction between the first magnet and the metallic material.

In other examples, in order to reduce the attraction force of the electronic device 100 in the folded state when the electronic device 100 is in the folded state, the processor 110 may control the coil 42 on the electronically controlled magnetic attraction to be energized in a scenario in which the electronic device is unfolded by a single hand of a user, thereby reducing the attraction force between the electronically controlled magnetic attraction and the metal material, and thus reducing the attraction force between the first housing 21 and the second housing 22.

For example, in a scenario where a user with a large finger force, such as a man or an athlete, wants to expand the electronic device 100 with less effort, the user can input a trigger operation to the electronic device 100 by pressing the auxiliary screen 30 for a long time, even though the user wants to expand the electronic device 100 with less effort. After the electronic device 100 senses a triggering operation, the processor 110 may control the current value of the coil 42 on the electronically controlled magnet to be equal to the first current value. In this way, by reducing the magnetic field strength of the magnetic field formed by the electrically controlled magnetic attraction member, the attraction force formed between the electrically controlled magnetic attraction member 40 and the metal material is reduced, and a certain attraction force is reserved, so that a certain damping sense is provided in the unfolding process.

In still other examples, in a scenario where the electronic device 100 is in a folded state, where a user needs to unfold the electronic device 100, and it is inconvenient to manually unfold the electronic device, the processor 110 may control the coil on the electronically controlled magnetic attraction 40 to be energized, so that the electronically controlled magnetic attraction 40 forms a magnetic field with a polarity opposite to that of the magnet, thereby forming a repulsive force between the electronically controlled magnetic attraction 40 and the metal material, and thus forming a repulsive force between the first housing 21 and the second housing 22.

For example, there are substances such as water, sweat, oil, glue, etc. on the hands of the user, which are inconvenient to spread the electronic device with fingers, and there is a need to spread the electronic device 100. The user may input a trigger operation to the electronic apparatus 100 through a gesture operation without touching the electronic apparatus 100. After the electronic device 100 senses a triggering operation, the processor 110 may control the current value of the coil 42 on the electronically controlled magnetic attraction 40 to be equal to the second current value. In this way, the electrically controlled magnetic attraction member 40 forms a magnetic field with a polarity opposite to that of the magnet, thereby forming a repulsive force between the electrically controlled magnetic attraction member 40 and the metal material, and further forming a repulsive force between the first housing 21 and the second housing 22, so as to realize automatic unfolding of the electronic device 100.

In the case of ambient light sensor 120, processor 110 may also obtain the ambient light level provided by ambient light sensor 120. The processor 110 may compare the ambient light level to a preset brightness threshold. In the case where the ambient light level is greater than or equal to the brightness threshold, the processor 110 considers that the electronic device 110 is not currently in a pocket or the like that requires activation of the anti-false touch function, and thus does not activate the anti-false touch function. In the case where the ambient light level is less than the brightness threshold, the processor 110 considers that the electronic device 100 is currently in a pocket or the like that needs to activate the anti-false touch function, and thus activates the anti-false touch function.

The processor 110 does not start the false touch preventing function, the electronic device 100 is in the false touch preventing state, and the processor 110 can adjust the electric signal of the coil 42 in the electric control magnetic attraction piece 40 under the condition that the processor 110 acquires the trigger signal, so that the magnetic field formed by the electric control magnetic attraction piece 40 is changed, the attraction force between the first magnetic attraction piece and the second magnetic attraction piece is reduced, and the user can conveniently expand the electronic device 100.

The processor 110 starts the false touch preventing function, and when the electronic device 100 is in the false touch preventing state, the processor 110 may not adjust the electrical signal of the coil 42 in the electrically controlled magnetic attraction piece 40 when the processor 110 acquires the trigger signal, so that the attraction force between the first magnetic attraction piece and the second magnetic attraction piece is not changed.

In summary, as shown in fig. 18, first, the electronic device first housing 21 and the second housing 22 are attracted to each other based on the electronic control magnetic attraction member of the electronic device; then, the user inputs preset trigger operation to the electronic equipment, and the electronic equipment can correspondingly form a trigger signal; then, the electronic device provides a trigger signal representing that the user wants to unfold the electronic device to the processor, so that the processor provides an electric signal to the electric control magnetic attraction piece; after the electric control magnetic attraction piece receives the electric signal, an electromagnetic field is formed, so that the magnetic field strength of the magnetic field formed by the electric control magnetic attraction piece is weakened, and the attraction force between the first shell 21 and the second shell 22 is weakened; finally, the user can deploy the electronic device with less effort.

The embodiment of the application also provides a control method of the electronic equipment.

The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the application, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 19 is a software configuration block diagram of the electronic device 100 of the embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 19, the application package may include applications such as a camera, gallery, calendar, map, WLAN, bluetooth, music, short message, anti-touch, electronically controlled magnetic attraction, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 19, the application framework layer may include a window management service, a content providing service, a resource management service, a notification management service, an off-screen display (always on display, AOD) service, and the like.

The window management service is used to manage window programs. The window management service may obtain the size of the display screen, determine whether there is a status bar, lock the screen, intercept the screen, etc.

The content providing service is used to store and retrieve data and make such data accessible to applications. Such data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The notification management service allows applications to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification management services are used to inform that the download is complete, message alerts, etc. The notification management service may also be a notification in the form of a chart or scroll bar text appearing in the system top status bar, such as a notification of a background running application, or a notification appearing on screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), two-dimensional graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

A two-dimensional graphics engine is a drawing engine that draws two-dimensional drawings.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a flexible screen driver, a touch integrated circuit, a camera driver, an audio driver, a sensor driver and the like.

The workflow of the electronic device 100 software and hardware is illustrated below in connection with a scenario in which a user deploys the electronic device with a single hand.

Fig. 20 is a flowchart of a control method of an electronic device according to some embodiments of the present application. The control method of the electronic device may include:

S001, the sensor senses the triggering operation.

Illustratively, as shown in fig. 13, the electronic device 100 includes a key 130, and the triggering operation performed by the corresponding user may include pressing the key.

Also illustratively, as shown in fig. 7 and 13, the electronic device 100 includes an auxiliary screen 30, and the corresponding user-performed triggering operations may include touch operations such as clicking the auxiliary screen 30, double clicking the auxiliary screen 30, long pressing the auxiliary screen 30, and sliding on the auxiliary screen 30.

As further illustrated in fig. 13, the electronic device 100 includes a camera 140, and the triggering operation performed by the corresponding user may include a space gesture operation, a facial expression, or the like.

As yet another example, as shown in fig. 13, the electronic device 100 may include a microphone 160 and the corresponding user-performed triggering operation may include voice instructions or other suitable sound instructions.

S002, the sensor forms a trigger signal in response to the trigger operation, and provides the trigger signal to the processor 110.

The sensor responds to the triggering operation as an analog signal, and correspondingly forms a triggering signal capable of representing the triggering operation characteristic. And provides a trigger signal to the processor 110.

S003, the processor 110 provides an electrical signal to the electronically controlled magnetic attraction 40 in response to the trigger signal.

The structure of the electrically controlled magnetic attraction member 40 has been described previously, and will not be described here again.

In some examples, the processor 110 does not distinguish between the trigger signals, and after determining that the trigger signal is received, provides a preset current to the coil 42 on the electronically controlled magnet 40 for energizing.

In other examples, the trigger operation may include a first trigger sub-operation and a second trigger sub-operation. It will be appreciated that the first trigger sub-operation and the second trigger sub-operation are two different trigger operations.

For example, in a scenario where a user with small finger strength, such as a woman or a student, wants to develop the electronic device 100 with less effort, the user may continuously press the key three times to input the first trigger operation to the electronic device 100. After the electronic device 100 senses the first trigger operation, the processor 110 may control the current value of the coil 42 on each electronically controlled magnet to increase from 0 to equal the first current value.

For another example, in a scenario where a user with smaller finger strength, such as an elderly person, wants to develop the electronic device 100 with less effort, the user may press the start key to input a second trigger operation to the electronic device 100. After the electronic device 100 senses the second trigger operation, the processor 110 may control the current value of the coil 42 on each electronically controlled magnetic attraction to increase from 0 to equal to the second current value.

S004, the electric control magnetic attraction piece 40 receives the electric signals to form an electromagnetic field.

The coil 42 in the electrically controlled magnetic attraction member 40 correspondingly forms an electromagnetic field after being electrified. The electromagnetic strength of the electromagnetic field has a positive correlation with the magnitude of the current in the coil 42. It will be appreciated that the greater the current value of the current in the coil 42, the greater the electromagnetic strength of the electromagnetic field; the smaller the current value of the current in the coil 42, the smaller the electromagnetic strength of the electromagnetic field.

Illustratively, the processor 110 provides a current of a first current value to the coil 42 on the electronically controlled magnet 40, such that the coil 42 forms a corresponding first electromagnetic field. Because the electromagnetic field formed by the coil 42 in the electrically controlled magnetic attraction piece 40 after being electrified is opposite to the permanent magnetic field formed by the permanent magnet, the electromagnetic field formed by the coil 42 can weaken the magnetic field strength formed by the electrically controlled magnetic attraction piece 40. Thus, the first superimposed magnetic field strength of the electronically controlled magnetic attraction element 40 is the difference between the magnetic field strength of the first electromagnetic field and the magnetic field strength of the permanent magnetic field.

Also illustratively, the processor 110 provides a current of a second current value to the coil 42 on the electronically controlled magnetic attraction 40, such that the coil 42 forms a corresponding second electromagnetic field. In the case where the first current value is smaller than the second current value, the magnetic field strength of the first electromagnetic field is smaller than the magnetic field strength of the second electromagnetic field, and the magnetic field strength of the second electromagnetic field is larger than the magnetic field strength of the permanent magnetic field.

Because the electromagnetic field formed after the coil 42 in the electric control magnetic attraction piece 40 is electrified is opposite to the permanent magnetic field formed by the permanent magnet, the magnetic field direction of the second superimposed magnetic field intensity of the electric control magnetic attraction piece 40 is opposite to the magnetic field direction of the permanent magnetic field, and the second superimposed magnetic field intensity of the electric control magnetic attraction piece 40 is the difference between the magnetic field intensity of the second electromagnetic field and the magnetic field intensity of the permanent magnetic field.

In this way, the electrically controlled magnetic attraction member 40 forms a magnetic field with a polarity opposite to that of the magnet, thereby forming a repulsive force between the electrically controlled magnetic attraction member 40 and the metal material, and further forming a repulsive force between the first housing 21 and the second housing 22, so as to realize automatic unfolding of the electronic device 100.

In the following description, with reference to fig. 21 and 22, when the electronic device 100 is in a folded state and the auxiliary screen 30 performs a screen-extinguishing display, a user inputs a trigger operation to the auxiliary screen 30 as an example:

as shown in fig. 21, the off-screen display service turns on a low power mode so that the touch driving interface can communicate with the input service in the off-screen display state. As shown in fig. 22, the user continuously clicks the auxiliary screen 30 in the screen-off display state for several times, the auxiliary screen 30 senses that the touch panel is triggered, and then the auxiliary screen 30 interrupts the uploading and is sent to the Touch (TP) integrated circuit ((integrated circuit, IC). TP IC processes the interruption uploading into an original input event (including information such as touch coordinates and time stamp of touch operation) and then stores the original input event in the kernel layer.

Further, when the auxiliary screen 30 performs the screen-off display and the electronic device 100 turns on the anti-false touch function, the user inputs a triggering operation to the auxiliary screen 30, which is described with reference to fig. 23:

as shown in fig. 23, the off-screen display service turns on a low power mode so that the touch driving interface can communicate with the input service in the off-screen display state. The user clicks the auxiliary screen 30 in the screen-off display state continuously for a plurality of times, and the auxiliary screen 30 interrupts uploading and is sent to the TP IC after sensing the triggering operation. The TP IC processes the interrupt upload into an original input event (including information such as touch coordinates, time stamp of touch operation and the like), and then saves the original input event in the kernel layer. An input (input) service of an application framework layer acquires an original input event from a touch driving interface of a kernel layer, and identifies an anti-false touch application corresponding to the input event. The anti-false touch application does not provide an input event to the power application for providing the electronic control magnetic attraction piece with an electrical signal when the ambient light level detected by the corresponding ambient light sensor is less than the preset threshold value, so that the electronic control magnetic attraction piece 40 does not undergo a magnetic field change. When the ambient light intensity detected by the corresponding ambient light sensor is greater than or equal to a preset threshold value, the anti-false application provides an input event to a power application for providing an electric signal to the electrically controlled magnetic attraction piece, so that the current of the coil 42 on the electrically controlled magnetic attraction piece 40 is controlled, and the coil 42 forms an electromagnetic field. Because the electromagnetic field formed by the coil 42 in the electric control magnetic attraction piece 40 after being electrified is opposite to the permanent magnetic field formed by the permanent magnet, the electromagnetic field formed by the coil 42 can weaken the magnetic field strength formed by the electric control magnetic attraction piece 40, thereby facilitating the unfolding of the electronic equipment by a user with one hand.

In this way, the electronic device 100 prevents the situation that the opening force of the electronic device 100 is reduced due to the false touch under the false touch prevention function, and ensures the stability of the folding state of the electronic device 100 under the false touch prevention scene.

The auxiliary screen 30 may also be displayed on a bright screen in conjunction with the electronic device 100 being in a folded state. The user inputs a trigger operation to the auxiliary screen 30 as an example, and description will be given with reference to fig. 24:

as shown in fig. 24, the touch-driven interface may communicate with the input service in the off-screen display state in the bright-screen display state. The user clicks the auxiliary screen 30 in the bright screen display state continuously for a plurality of times, and the auxiliary screen 30 interrupts uploading and is sent to the TP IC after sensing the triggering operation. The TP IC sends the interrupt to the touch drive processor through the touch drive interface, and the touch drive processor processes the interrupt into an original input event (including information such as touch coordinates and time stamps of touch operations) and then stores the original input event in the kernel layer. An input (input) service of the application framework layer obtains an original input event from a touch driving interface of the kernel layer, and identifies a power supply application corresponding to the input event and used for providing an electric signal for the electric control magnetic attraction piece, so that current of a coil 42 on the electric control magnetic attraction piece 40 is controlled, and the coil 42 forms an electromagnetic field. Because the electromagnetic field formed by the coil 42 in the electric control magnetic attraction piece 40 after being electrified is opposite to the permanent magnetic field formed by the permanent magnet, the electromagnetic field formed by the coil 42 can weaken the magnetic field strength formed by the electric control magnetic attraction piece 40, thereby facilitating the unfolding of the electronic equipment by a user with one hand.

The touch driven processor may include, among other things, a touch optical drive (touch panel deamon) and a transparent large page (transparent huge pages, THP). Of course, the touch drive processor may also include other drive content, which is not limited herein.

Further, when the auxiliary screen 30 performs the bright screen display and the electronic device 100 turns on the anti-false touch function, the user inputs the triggering operation to the auxiliary screen 30, which is described with reference to fig. 25:

as shown in fig. 25, the touch driving interface may communicate with the input service in the idle screen display state in the bright screen display state. The user clicks the auxiliary screen 30 in the bright screen display state continuously for a plurality of times, and the auxiliary screen 30 interrupts uploading and is sent to the TP IC after sensing the triggering operation. The TP IC sends the interrupt to the touch drive processor through the touch drive interface, and the touch drive processor processes the interrupt into an original input event (including information such as touch coordinates and time stamps of touch operations) and then stores the original input event in the kernel layer. An input (input) service of an application framework layer acquires an original input event from a touch driving interface of a kernel layer, and identifies an anti-false touch application corresponding to the input event. The anti-false touch application does not provide an input event to the power application for providing the electronic control magnetic attraction piece with an electrical signal when the ambient light level detected by the corresponding ambient light sensor is less than the preset threshold value, so that the electronic control magnetic attraction piece 40 does not undergo a magnetic field change. When the ambient light intensity detected by the corresponding ambient light sensor is greater than or equal to a preset threshold value, the anti-false application provides an input event to a power application for providing an electric signal to the electrically controlled magnetic attraction piece, so that the current of the coil 42 on the electrically controlled magnetic attraction piece 40 is controlled, and the coil 42 forms an electromagnetic field. Because the electromagnetic field formed by the coil 42 in the electric control magnetic attraction piece 40 after being electrified is opposite to the permanent magnetic field formed by the permanent magnet, the electromagnetic field formed by the coil 42 can weaken the magnetic field strength formed by the electric control magnetic attraction piece 40, thereby facilitating the unfolding of the electronic equipment by a user with one hand.

According to the control method of the electronic equipment, provided by the embodiment of the application, the opening force required by unfolding the electronic equipment is reduced by reducing the magnetic force of mutual attraction between the magnetic attraction pieces at two sides of the folding, so that a user can easily unfold the electronic equipment in a scene of needing to unfold by one hand or needing to unfold the folding equipment in a labor-saving mode.

Embodiments of the present application also provide a computer readable storage medium, where the computer readable storage medium includes computer instructions, which when executed on an electronic device (such as a folding mobile phone) described above, cause the electronic device to perform the functions or steps performed by the folding apparatus in the method embodiment described above.
