Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background Art

[0002] With the rapid development of electronic devices such as smartphones, tablets, and e-readers, foldable screen technology has emerged. Electronic devices that use foldable screen technology can unfold the screen to have a relatively large display area, or fold it to have a relatively small footprint, making it easy to carry and helping to improve the flexibility of the structure and display function of electronic devices. However, currently, electronic devices with foldable screens are difficult to open, affecting the user experience. Summary of the invention

[0003] An embodiment of the present application provides an electronic device to solve the problem of difficulty in opening a foldable screen.

[0004] An electronic device, comprising:

[0005] A housing assembly comprises a first housing and a second housing, wherein the first housing and the second housing can rotate relative to each other to be unfolded or folded;

[0006] A first magnet, disposed in the first shell;

[0007] A second magnet is disposed in the second shell;

[0008] A sensing element for sensing an object to be detected; and

[0009] A driving element, disposed on the housing assembly;

[0010] When the first shell and the second shell are folded relative to each other, if the sensor element senses the detected object, the driving element can drive the first magnet and the second magnet to face each other with the same poles, so that the first shell and the second shell are opened under the action of magnetic repulsion.

[0011] In the electronic device, when the first shell and the second shell are folded relative to each other, to open the first shell and the second shell, the user only needs to move the hand to the sensing surface of the sensor element. When the sensor element senses that there is a detected object on the sensing surface, the driving element can drive the first magnet and the second magnet to face each other with the same poles so that the first shell and the second shell are opened under the action of magnetic repulsion, thereby realizing the automatic opening operation of the electronic device. Therefore, the automatic opening operation of the electronic device is convenient and labor-saving, which is conducive to improving the user experience. Moreover, the sensing is performed by the sensor element, and no additional buttons are required for the opening operation, which is conducive to maintaining the integrity of the appearance of the electronic device.

[0025] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the structure of the electronic device 10 in some embodiments in an unfolded state, Figure 2 is a schematic diagram of the structure of the electronic device 10 in a folded state in some embodiments, Figure 3 Schematic diagram of the structure of the electronic device 10 in a folded state in some embodiments. In some embodiments, the electronic device 10 includes a housing assembly 11 and a flexible screen 12, the housing assembly 11 includes a first housing 111 and a second housing 112 that can rotate relative to each other, and the flexible screen 12 is connected to the first housing 111 and the second housing 112, and can be unfolded or folded with the rotation of the first housing 111 and the second housing 112. In this application, for the convenience of description, the part of the flexible screen 12 provided on the first housing 111 is referred to as the first screen 121, and the part of the flexible screen 12 provided on the second housing 112 is referred to as the second screen 122.

[0026] It is understood that when the electronic device 10 is in the unfolded state, the first screen 121 and the second screen 122 can be coplanar and used as a display screen to have a relatively large display area. When the electronic device 10 is in the folded state, the first screen 121 and the second screen 122 are relatively tilted, and the first screen 121 and the second screen 122 can display different contents respectively to be used as two display screens. When the electronic device 10 is in the folded state, the first screen 121 and the second screen 122 are relatively stacked, which can minimize the occupied space of the electronic device 10 to facilitate carrying. In some embodiments, as the first shell 111 and the second shell 112 rotate relative to each other, the angle between the first screen 121 and the second screen 122 has a maximum angle and a minimum angle. In the present application, when the first screen 121 and the second screen 122 are relatively rotated to the maximum angle, the state of the flexible screen 12 is referred to as the unfolded state, and the first screen 121 and the second screen 122 can also be referred to as being in the unfolded state, or the first shell 111 and the second shell 112 are in the unfolded state, or the electronic device 10 is in the unfolded state. When the first screen 121 and the second screen 122 are relatively rotated to the minimum angle, the state of the flexible screen 12 is called a folded state, and the first screen 121 and the second screen 122 are also called in a folded state, or the first shell 111 and the second shell 112 are in a folded state, or the electronic device 10 is in a folded state. When the angle between the first screen 121 and the second screen 122 is between the maximum angle and the minimum angle, the state of the flexible screen 12 is called a folded state, and the first screen 121 and the second screen 122 are also called in a folded state, or the first shell 111 and the second shell 112 are in a folded state, or the electronic device 10 is in a folded state.

[0027] In some embodiments, when the electronic device 10 is in the unfolded state, the first screen 121 and the second screen 122 are coplanar, that is, the maximum angle between the first screen 121 and the second screen 122 is 180°, and when the electronic device 10 is in the folded state, the opposing surfaces of the first screen 121 and the second screen 122 are in contact, that is, the minimum angle between the first screen 121 and the second screen 122 is 0°. Of course, the above are only some examples of the angle design between the first screen 121 and the second screen 122. In other embodiments, the angle range between the first screen 121 and the second screen 122 can also have other designs to meet more needs. For example, the maximum angle between the first screen 121 and the second screen 122 can also be any angle greater than 180°, or an obtuse angle less than 180°, and the minimum angle between the first screen 121 and the second screen 122 can be any acute angle greater than 0°.

[0028] In the present application, the electronic device 10 can be any electronic product such as a smart phone, a tablet computer, an e-reader, etc. configured with a flexible screen 12. The first screen 121 and the second screen 122 of the electronic device 10 can be rotated to different angles relative to the first shell 111 and the second shell 112, so that the electronic device 10 is in an unfolded state, a folded state or a closed state to meet the needs of large-screen display, multi-screen display or easy carrying, thereby improving the flexibility of the structure and display function of the electronic device 10.

[0029] Furthermore, combined with Figure 4 and Figure 5 As shown, in some embodiments, the electronic device 10 further includes a first magnet 13, a second magnet 14, a driving element 15 and a sensing element 16. The first magnet 13 is disposed in the first housing 111, and the second magnet 14 is disposed in the second housing 112. When the first housing 111 and the second housing 112 are folded relative to each other, the first magnet 13 and the second magnet 14 are disposed relative to each other. The driving element 15 is disposed in the first housing 111 or the second housing 112, and the driving element 15 is configured to drive the magnetic pole direction of at least one of the first magnet 13 and the second magnet 14 to change, so that the first magnet 13 and the second magnet 14 are opposite to each other with the same poles. The sensing element 16 has a sensing surface, and the sensing element 16 is configured to sense whether there is a detected object on one side of the sensing surface of the sensing element 16. The driving element 15 and the sensing element 16 are communicatively connected via any suitable connection method such as a wire or Bluetooth. When the first shell 111 and the second shell 112 are folded relative to each other, if the sensing element 16 senses that there is a detected object on one side of the sensing surface, the sensing element 16 can send a signal to the driving element 15, so that the driving element 15 drives the first magnet 13 and the second magnet 14 to face each other with the same poles, thereby making the first shell 111 and the second shell 112 open under the action of the magnetic repulsion force, thereby realizing the automatic opening operation of the first shell 111 and the second shell 112.

[0030] For the electronic device 10, when the first shell 111 and the second shell 112 are folded relative to each other, to open the first shell 111 and the second shell 112, the user only needs to move the hand to the sensing surface side of the sensor element 16. When the sensor element 16 senses that there is a detected object on one side of the sensing surface, the driving element 15 can drive the first magnet 13 and the second magnet 14 to face each other with the same poles so that the first shell 111 and the second shell 112 are opened under the action of the magnetic repulsive force, thereby realizing the automatic opening operation of the electronic device 10. As a result, the automatic opening operation of the electronic device 10 is convenient and labor-saving. When opening, there is no need to overcome the magnetic attraction force to forcefully pry apart the first shell 111 and the second shell 112, which is conducive to improving the user experience. Moreover, by sensing through the sensor element 16, there is no need to set an additional button for the opening operation, which is conducive to maintaining the integrity of the appearance of the electronic device 10. It is understandable that when the first shell 111 and the second shell 112 are automatically opened by the induction of the sensor element 16, the first shell 111 and the second shell 112 can be opened at a certain angle under the magnetic repulsion of the first magnet 13 and the second magnet 14 and enter the folded state, so that the user can more conveniently rotate the first shell 111 and the second shell 112 to the unfolded state. The angle at which the first shell 111 and the second shell 112 are opened to enter the folded state is not limited, and can be specifically set according to the magnitude of the magnetic repulsion of the first magnet 13 and the second magnet 14 and the rotational resistance between the first shell 111 and the second shell 112.

[0031] The specific configuration of the first magnet 13, the second magnet 14, and the driving element 15 is not limited, as long as the driving element 15 can drive the first magnet 13 and the second magnet 14 to face each other with the same poles, so that the first shell 111 and the second shell 112 are automatically opened under the action of the magnetic repulsion force of the first magnet 13 and the second magnet 14. In some embodiments, the first magnet 13 and the second magnet 14 can both be magnets, and the driving element 15 is configured to be able to drive at least one of the first magnet 13 and the second magnet 14 to rotate so that the first magnet 13 and the second magnet 14 face each other with the same poles.

[0032] refer to Figure 4 and Figure 5As shown, when the first shell 111 and the second shell 112 are folded relative to each other, the first magnet 13 and the second magnet 14 are oppositely polarized, and the magnetic attraction force between the first magnet 13 and the second magnet 14 is greater than the force that tends to open the first shell 111 and the second shell 112, so that the first shell 111 and the second shell 112 can maintain the folded state under the action of the magnetic attraction force between the first magnet 13 and the second magnet 14. The driving element 15 can be an electrode or a motor, the first magnet 13 is fixedly arranged in the first shell 111, and the second magnet 14 is connected to the output shaft of the driving element 15, and can rotate relative to the second shell 112 under the drive of the output shaft of the driving element 15. When the first shell 111 and the second shell 112 are folded relative to each other, if the first shell 111 and the second shell 112 need to be opened, the user can move the hand to the side of the sensing surface of the sensor element 16. When the sensor element 16 senses the presence of the detected object on one side of the sensing surface, the driving element 15 drives the second magnet 14 to rotate and change the magnetic pole direction of the second magnet 14, so that the first magnet 13 and the second magnet 14 are converted from opposite poles to the same poles, so that the first shell 111 and the second shell 112 automatically pop open under the magnetic repulsion force of the first magnet 13 and the second magnet 14.

[0033] In other embodiments, at least one of the first magnet 13 and the second magnet 14 may also be an electromagnet, and the driving element 15 is configured to be able to change the current direction of at least one of the first magnet 13 and the second magnet 14 so that the first magnet 13 and the second magnet 14 are opposite to each other with the same poles. For example, in some embodiments, the first magnet 13 is a magnet fixedly arranged in the first shell 111, and the second magnet 14 is an electromagnet fixedly arranged in the second shell 112. When the first shell 111 and the second shell 112 are folded relative to each other, the current flows through the second magnet 14 to generate magnetism, and the first magnet 13 and the second magnet 14 are opposite to each other with different poles. When the first shell 111 and the second shell 112 need to be opened, the user can move the hand to the sensing surface side of the sensor element 16. When the sensor element 16 senses that there is a detected object on the sensing surface side, the driving element 15 changes the direction of the current applied to the second magnet 14, thereby changing the magnetic pole direction of the second magnet 14, so that the first magnet 13 and the second magnet 14 are opposite to each other with the same poles, thereby opening the first shell 111 and the second shell 112. In this embodiment, the driving element 15 can be a component that applies voltage to the second magnet 14. The driving element 15 can apply two voltages with opposite positive and negative directions to the second magnet 14, so that the first magnet 13 and the second magnet 14 are opposite to each other with the same poles or opposite poles.

[0034] It should be noted that, in some embodiments, the magnetic pole directions of the first magnet 13 and the second magnet 14 may also have a reset function. For example, when the first magnet 13 and the second magnet 14 are facing each other with the same poles so that the first shell 111 and the second shell 112 are opened, the stimulation directions of the first magnet 13 and the second magnet 14 may be reset to facing each other with opposite poles, so that when the first shell 111 and the second shell 112 need to be folded, the user only needs to drive the first shell 111 and the second shell 112 closer to each other until the magnetic force between the first magnet 13 and the second magnet 14 is greater than the force that tends to open the first shell 111 and the second shell 112, and the first shell 111 and the second shell 112 can be automatically folded and maintained in the folded state under the magnetic attraction force of the first magnet 13 and the second magnet 14. Such a configuration is conducive to simplifying the closing operation of the first shell 111 and the second shell 112. At the same time, when the first shell 111 and the second shell 112 are folded relative to each other, the folded state of the first shell 111 and the second shell 112 can be maintained more stably, and the flexible screen 12 can be protected between the first shell 111 and the second shell 112 to prevent the flexible screen 12 from being damaged due to scratches.

[0035] In some embodiments, when the first magnet 13 and the second magnet 14 are both magnets, the electronic device 10 may further include a reset element (not shown in the figure), and the reset element includes but is not limited to an elastic element such as a torsion spring. The reset element is connected to the second magnet 14, and when the first magnet 13 and the second magnet 14 are opposite to each other, the reset element is in a natural state. When the driving element 15 drives the second magnet 14 to rotate until the first magnet 13 and the second magnet 14 are opposite to each other with the same poles, so that the first shell 111 and the second shell 112 are automatically opened, the second magnet 14 drives the reset element to deform so that the reset element has an elastic force tending to restore. When the first shell 111 and the second shell 112 are opened, the second magnet 14 can be reset to the first magnet 13 and the second magnet 14 opposite to each other with the elastic force of the reset element. When the second magnet 14 is an electromagnet, the driving element 15 can change the direction of the current applied to the second magnet 14 again after the first shell 111 and the second shell 112 are opened, so that the first magnet 13 and the second magnet 14 are reset to the state of opposite poles.

[0036] refer to Figure 6As shown, in some embodiments, a plurality of first magnets 13 and a plurality of second magnets 14 may be provided, and the plurality of first magnets 13 are sequentially spaced apart in a direction parallel to the rotation axis of the first shell 111 and the second shell 112, and the plurality of second magnets 14 are sequentially spaced apart in a direction parallel to the rotation axis of the first shell 111 and the second shell 112, and when the first shell 111 and the second shell 112 are folded relative to each other, the first magnets 13 and the second magnets 14 are opposite to each other one by one. The plurality of first magnets 13 and the second magnets 14 are spaced apart, and when the first shell 111 and the second shell 112 are folded relative to each other, the first magnets 13 and the second magnets 14 can exert magnetic attraction on the first shell 111 and the second shell 112 at different positions, so that the folded state of the first shell 111 and the second shell 112 is more stable.

[0037] It is understandable that when the first shell 111 and the second shell 112 need to be opened, the driving element 15 can drive the magnetic pole directions of the plurality of second magnets 14 to change, so that a magnetic repulsive force is generated between the plurality of second magnets 14 and the first magnet 13 to open the first shell 111 and the second shell 112. At this time, the driving element 15 can be connected to the plurality of second magnets 14 at the same time, or the electronic device 10 can be provided with a plurality of driving elements 15, and the plurality of driving elements 15 are connected to the plurality of second magnets 14 one by one.

[0038] In other embodiments, the first shell 111 and the second shell 112 may also be provided with other magnetic elements relative to and different from the first magnet 13 and the second magnet 14, respectively. When the first shell 111 and the second shell 112 need to be opened, the driving element 15 only drives the magnetic pole direction of one of the second magnets 14 to change, so that the first magnet 13 and the second magnet 14 generate a magnetic repulsive force, as long as the magnetic repulsive force between the first magnet 13 and the second magnet 14 is greater than the sum of the magnetic attractive forces of other relative magnetic elements, so that the first shell 111 and the second shell 112 can be automatically opened under the action of the magnetic repulsive force. The provision of other magnetic elements can make the fixation of the first shell 111 and the second shell 112 in the folded state more stable.

[0039] In some embodiments, the first shell 111 has a first side surface 1111 facing away from the second shell 112 when unfolded, and the second shell 112 has a second side surface 1121 facing away from the first shell 111 when unfolded. The sensor element 16 is disposed on the first shell 111 or the second shell 112, and when the sensor element 16 is disposed on the first shell 111, the sensing surface of the sensor element 16 is disposed corresponding to the first side surface 1111. In other words, when the user's hand moves to the side where the first side surface 1111 is located and corresponds to the position of the sensor element 16, the sensor element 16 can sense that there is a detected object on one side of the sensing surface. When the sensor element 16 is disposed on the second shell 112, the sensing surface of the sensor element 16 is disposed corresponding to the second side surface 1121. In other words, when the user's hand moves to the side where the second side surface 1121 is located and corresponds to the position of the sensor element 16, the sensor element 16 can sense that there is a detected object on one side of the sensing surface. It is understandable that when the user opens the first shell 111 and the second shell 112, the user usually places the thumb on the first side surface 1111 and / or the second side surface 1121. Therefore, the sensing surface of the sensor element 16 is set to correspond to the first side surface 1111 and / or the second side surface 1121, which can adapt to the user's opening operation habits. When the user's thumb is sensed to be placed on the first side surface 1111 and / or the second side surface 1121, the first shell 111 and the second shell 112 are opened. The setting of the sensor element 16 does not change the user's opening habits, thereby improving the user's use experience.

[0040] In some embodiments, the electronic device 10 may also be provided with two sensor elements 16, which are respectively provided in the first shell 111 and the second shell 112, and the sensing surfaces of the two sensor elements 16 are respectively provided corresponding to the first side surface 1111 and the second side surface 1121. When any sensor element 16 senses that there is a detected object on one side of the sensing surface, the driving element 15 can drive the first magnet 13 and the second magnet 14 to face each other with the same poles to open the first shell 111 and the second shell 112. With such a configuration, the user's thumb can be moved to any one of the first side surface 1111 and the second side surface 1121 to realize the automatic opening operation, which is conducive to improving the sensitivity of the opening operation sensing and improving the user experience.

[0041] Further, refer to Figure 6 As shown, in some embodiments, two sensing elements 16 are respectively disposed in the first shell 111 and the second shell 112, and the sensing surfaces of the two sensing elements 16 are respectively disposed at positions away from each other on the first side surface 1111 and the second side surface 1121. Such a configuration is conducive to expanding the sensing range of the sensing element 16 on the first side surface 1111 and the second side surface 1121, improving the sensitivity of the opening sensing operation, and better adapting to the user's opening operation, thereby improving the user's use experience.

[0042] It should be noted that Figure 6 The illustrated embodiments only illustrate the locations of the sensing element 16, the first magnet 13, and the second magnet 14 in some embodiments. According to the shape of the electronic device 10, the user's operating habits, and other requirements, the number and location of the sensing element 16, the first magnet 13, and the second magnet 14 may have any other applicable settings, which will not be described in detail in this application. In addition, the sensing element 16, the first magnet 13, and the second magnet 14 may be accommodated in the first housing 111 and / or the second housing 112. Figure 6 In the illustrated embodiment, only dotted lines are used to indicate the approximate installation positions of the sensor element 16, the first magnet 13, and the second magnet 14 on the shell assembly 11, which does not mean that the sensor element 16, the first magnet 13, and the second magnet 14 are exposed. The sensor element 16 can be exposed or hidden in the shell assembly 11. The sensor element 16, the first magnet 13, and the second magnet 14 cannot be observed from the outside of the electronic device 10, which can improve the appearance integrity of the electronic device 10.

[0043] The specific type of the sensor element 16 is not limited, as long as the sensor element 16 can sense whether there is a detected object on one side of the sensing surface. In some embodiments, the sensor element 16 includes but is not limited to a pressure sensor, a capacitive sensor or an optical sensor. When the sensor element 16 is a pressure sensor, if the user touches the position of the electronic device 10 corresponding to the sensor element 16, the sensor element 16 can sense the user's touch pressure, thereby sensing the presence of the detected object on one side of the sensing surface. When the sensor element 16 is a pressure sensor, the sensor element 16 includes but is not limited to a gauge pressure sensor, a differential pressure sensor, an absolute pressure sensor, etc. When the sensor element 16 is a capacitive sensor, if the user touches the position of the electronic device 10 corresponding to the sensor element 16, the sensor element 16 can sense the capacitance change, thereby sensing the presence of the detected object on one side of the sensing surface. When the sensor element 16 is an optical sensor, if the user's hand moves to the position of the electronic device 10 corresponding to the sensor element 16, the user's hand will block the light on one side of the sensing surface, so that the sensor element 16 can sense the presence of the detected object on one side of the sensing surface.

[0044] In some embodiments, the electronic device 10 may further include a control element 17, which is communicatively connected to the sensor element 16 and the drive element 15. When the first housing 111 and the second housing 112 are relatively folded, if the sensor element 16 senses that there is a detected object on one side of the sensing surface, the sensor element 16 can send a signal to the control element 17, and the control element 17 can control the drive element 15 to drive the first magnet 13 and the second magnet 14 to face each other with the same poles according to the signal sent by the sensor element 16. The control element 17 can be a central processor of the electronic device 10, or a control chip in the electronic device 10 specifically used to realize the control function of the drive element 15.

[0045] Furthermore, in some embodiments, the control element 17 is configured to determine whether the time when the detected object exists on one side of the sensing surface reaches a preset time according to the sensing result of the sensor element 16, and when the time when the detected object exists on one side of the sensing surface reaches a preset time, control the driving element 15 to drive the first magnet 13 and the second magnet 14 to face each other with the same poles. Thus, when the user's hand stays on one side of the sensing surface for a preset time, the control element 17 controls the driving element 15 to drive the first magnet 13 and the second magnet 14 to face each other with the same poles, thereby realizing the automatic opening operation of the first shell 111 and the second shell 112, and preventing the user from misoperating and causing the first shell 111 and the second shell 112 to be opened by mistake. The preset time can be designed according to the user's usage habits, for example, it can be 3 seconds, 5 seconds, etc.

[0046] In some embodiments, the electronic device 10 may further include a first Hall sensor 18, which is disposed in the second housing 112 and is used to sense the magnetic field strength of the first magnet 13. The control element 17 is also configured to be able to determine whether the magnetic field strength sensed by the first Hall sensor 18 is greater than the preset magnetic field strength, and to control the flexible screen 12 to turn off the screen when the magnetic field strength sensed by the first Hall sensor 18 is greater than the preset magnetic field strength, and to control the flexible screen 12 to turn on the screen when the magnetic field strength sensed by the first Hall sensor 18 is less than the preset magnetic field strength. It can be understood that in the process of the first housing 111 and the second housing 112 rotating relative to switch from the folded state to the unfolded state, the angle between the first housing 111 and the second housing 112 gradually increases, the distance between the first magnet 13 and the first Hall sensor 18 gradually increases, and the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 gradually decreases. When the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 is less than the preset magnetic field strength, the control element 17 controls the flexible screen 12 to turn on the screen, and the automatic screen light action can be realized. During the relative rotation of the first shell 111 and the second shell 112 to switch from the unfolded state to the folded state, the angle between the first shell 111 and the second shell 112 gradually decreases, the distance between the first magnet 13 and the first Hall sensor 18 gradually decreases, and the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 gradually increases. When the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 is greater than the preset magnetic field strength, the control element 17 controls the flexible screen 12 to turn off the screen, so that the automatic screen-off action can be achieved.

[0047] Thus, the setting of the first Hall sensor 18 can realize the automatic screen-on action of the electronic device 10 when it tends to unfold, and the automatic screen-off action when it tends to fold, so that the operation of the electronic device 10 is more intelligent, and the user experience is improved. At the same time, the screen can be turned off in time when the first shell 111 and the second shell 112 tend to fold, and the energy consumption of the electronic device 10 is reduced. Of course, the setting of the preset magnetic field strength is not limited, and it can be set according to the user's usage habits. For example, the preset magnetic field strength can correspond to the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 when the angle between the first shell 111 and the second shell 112 is 80°. In other words, when the angle between the first shell 111 and the second shell 112 is greater than 80°, the control element 17 controls the flexible screen 12 to automatically turn on the screen, and when the angle between the first shell 111 and the second shell 112 is less than 80°, the control element 17 controls the flexible screen 12 to automatically turn off the screen, so as to better adapt to the user's usage habits and improve the usage experience.

[0048] It is understandable that the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18 will change in real time as the angle between the first shell 111 and the second shell 112 changes. Therefore, the control element 17 can also be configured to obtain the folding angle of the first shell 111 and the second shell 112 according to the magnetic field strength of the first magnet 13 sensed by the first Hall sensor 18, so that the use of the electronic device 10 is more precise and intelligent. For example, during the manufacturing process of the electronic device 10, the corresponding relationship between the magnetic field strength sensed by the first Hall sensor 18 and the angle between the first shell 111 and the second shell 112 can be preset in the control element 17, so that the folding angle between the first shell 111 and the second shell 112 can be obtained according to the magnetic field strength sensed by the first Hall sensor 18 during use.

[0049] Of course, in some embodiments, the electronic device 10 may be provided with a second Hall sensor, which may be provided in the first housing 111 and used to sense the magnetic field strength of the second magnet 14. The control element 17 may control the screen-off and screen-on actions of the flexible screen 12 according to the magnetic field strength sensed by the second Hall sensor, and / or obtain the folding angle of the first housing 111 and the second housing 112. The specific settings of the second Hall sensor and the control element 17 can refer to the settings of the first Hall sensor 18 and the control element 17, which will not be repeated here. Only one of the first Hall sensor 18 and the second Hall sensor may be provided, or both may be provided to improve the sensitivity and accuracy of the electronic device 10.

Those skilled in the art will understand that Figure 7 The structure of the electronic device 10 shown in the figure does not constitute a limitation on the electronic device 10, and the electronic device 10 may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0051] The radio frequency circuit 501 can be used to send and receive information, or receive and send signals during a call. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Usually, the radio frequency circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the radio frequency circuit 501 can also communicate with the network and other devices through wireless communication.

[0052] The memory 502 can be used to store applications and data. The applications stored in the memory 502 contain executable codes. The applications can be composed of various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0053] The input unit 503 can be used to receive input numbers, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touchpad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable detected objects or accessories on or near the touch-sensitive surface), and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

[0054] The display unit 504 can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device 10, which can be composed of graphics, text, icons, videos and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Figure 7 In the embodiment, the touch sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch sensitive surface and the display panel can be integrated to implement input and output functions. It can be understood that the display screen 110 can include an input unit 503 and a display unit 504.

[0055] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel according to the brightness of the ambient light, and the proximity sensor may turn off the display panel and / or backlight when the electronic device 10 is moved to the ear. As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the electronic device 10 can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0056] The audio circuit 506 can provide an audio interface between the user and the electronic device 10 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit it to the speaker, and convert it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and then the audio data is output to the processor 508 for processing, and then sent to another electronic device 10 through the radio frequency circuit 501, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 10.

[0057] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 10 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Figure 7 The wireless fidelity module 507 is shown, but it is understandable that it is not a necessary component of the electronic device 10 and can be omitted as needed without changing the essence of the invention.

[0058] The processor 508 is the control center of the electronic device 10. It uses various interfaces and lines to connect various parts of the entire electronic device 10. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 10 and processes data, thereby monitoring the electronic device 10 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 508.

[0059] The electronic device 10 also includes a power supply 509 for supplying power to various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, so that the power management system can manage charging, discharging, and power consumption.

[0060] although Figure 7 Not shown, the electronic device 10 may also include a Bluetooth module, etc., which will not be described in detail here. In specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined and implemented as the same or several entities. The specific implementation of the above modules can refer to the previous method embodiment, which will not be described in detail here.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
