[0007] an electronic device having a sensor module;

[0008] A bracket having a magnetic module;

[0009] When the electronic device is mounted on the bracket, the sensor module and the magnetic module are correspondingly arranged to enable the electronic device to identify the bracket and enter a preset working mode.

[0010] The alignment recognition system provided in the embodiment of the present application, by setting a sensor module on the electronic device and a magnetic module corresponding to the Hall sensor on the bracket, enables the sensor module on the electronic device to identify the preset mode corresponding to the magnetic module on the bracket when the electronic device is installed on the bracket, so that the electronic device automatically enters the corresponding preset working mode, without the need for user operation and is simple and practical.

[0033] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only intended to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and not all examples. All other examples obtained by those of ordinary skill in the art without creative work are intended to fall within the scope of protection of this application.

[0034] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Currently, electronic devices such as mobile phones can be configured with different operating modes based on user needs, allowing the phone to operate in different ways under different operating modes. For example, a phone can be set to airplane mode, in which all communication signals are cut off to avoid interfering with aircraft, etc. A phone can also be set to meeting mode, in which incoming calls or messages are notified by vibration or flashing indicator lights to avoid disrupting the meeting process. A phone can also be set to driving mode, in which the phone can voice announce incoming calls or received messages, improving driving safety while preventing users from missing important information.

[0036] Currently, mobile phones typically have two operating modes: manual operation and voice control. However, in both manual and voice control modes, users often overlook the existence of these modes or use them infrequently. Therefore, a new alignment recognition technology system is needed that can automatically enable electronic devices to enter a preset operating mode.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 is a cross-sectional schematic diagram of the alignment recognition system provided in an embodiment of the present application, Figure 2 yes Figure 1 A cross-sectional schematic diagram of another embodiment of the alignment recognition system. The embodiment of the present application provides an alignment recognition system 1000, which may include an electronic device 100 and a bracket 200. When the electronic device 100 is installed on the bracket 200, the electronic device 100 can recognize the bracket 200 and automatically enter a preset working mode. Specifically, the electronic device 100 may include a sensor module 71, and the bracket 200 may include a magnetic module. When the electronic device 100 is installed on the bracket 200, the sensor module 71 may be set corresponding to the magnetic module, that is, the sensor module 71 can recognize the magnetic module, so that the electronic device 100 can recognize the bracket 200, so that the electronic device 100 automatically enters the preset working mode.

[0038] It should be noted that the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0039] Please refer to Figure 3 , Figure 3 yes Figure 1The electronic device 100 can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Figure 3 (Only one form is shown exemplarily). Specifically, the electronic device 100 can be a mobile phone or smart phone (e.g., an iPhone™-based phone or an Android™-based phone), a portable gaming device (e.g., a Nintendo DS™, a PlayStation Portable™, a Gameboy Advance™, an iPhone™), a laptop computer, a PDA, a portable internet device, a music player, a data storage device, other handheld devices, and headphones. The electronic device 100 can also be other wearable devices that require charging (e.g., a head-mounted device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

[0040] The electronic device 100 can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0041] In some cases, electronic device 100 can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, electronic device 100 can be a device such as a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, an earpiece device, or other compact portable device.

[0042] The bracket 200 may be a vehicle bracket for holding the electronic device 100 , a container for accommodating the electronic device 100 , a storage bag, or other structures capable of mounting the electronic device 100 , which are not listed here one by one.

[0043] For example, when the electronic device 100, such as a mobile phone, needs to be in flight mode, the mobile phone can be placed in a holder 200, such as a storage bag (specifically, it can be a storage bag in the back seat of an airplane). The sensor module 71 of the electronic device 100 corresponds to the magnetic module setting of the holder 200 and recognizes the magnetic module, so that the electronic device 100 can recognize the holder 200 and put the electronic device 100 (specifically, the mobile phone) into flight mode.

[0044] For another example, when the electronic device 100, such as a mobile phone, needs to be in conference mode, the mobile phone can be placed on a bracket 200, such as a fixed table (specifically a designated position on a conference table). The sensor module 71 of the electronic device 100 corresponds to the magnetic module setting of the bracket 200 and identifies the magnetic module, so that the electronic device 100 can identify the bracket 200 and put the electronic device 100 (specifically a mobile phone) into conference mode.

[0045] For another example, when the electronic device 100, such as a mobile phone, needs to be in driving mode, the mobile phone can be installed on a bracket 200, such as a clamp bracket (specifically, it can be a special clamp bracket for fixing the mobile phone on the car), and the sensor module 71 of the electronic device 100 corresponds to the magnetic module setting of the bracket 200 and recognizes the magnetic module, so that the electronic device 100 can recognize the bracket 200 and put the electronic device 100 (specifically the mobile phone) into driving mode.

[0046] In this embodiment, the electronic device 100 may include a shell assembly 10, a flexible screen module 20 and a guide member 30. The shell assembly 10 is a hollow structure, and the flexible screen module 20, the guide member 30, etc. can be arranged in the shell assembly 10. The electronic device 100 may also include a circuit board (not shown) and a battery (not shown), and the circuit board and the battery can be arranged in the shell assembly 10. The circuit board can integrate the processor, power management module, storage unit and baseband chip of the electronic device 100. The flexible screen module 20 is communicatively connected to the processor, and the battery can power the flexible screen module 20 and the electronic components on the circuit board. Of course, the electronic device 100 may also include a camera module 40, which is communicatively connected to the circuit board, and the battery can power the camera module 40. It can be understood that the electronic device 100 of the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices 100. In the embodiment of the present application, a mobile phone is taken as an example for explanation.

[0047] Please refer to Figures 3 to 6 , Figure 3 yes Figure 1 The three-dimensional schematic diagram of the electronic device in the alignment recognition system is shown. Figure 4 yes Figure 3 Exploded diagram of the electronic device shown, Figure 5 yes Figure 4The three-dimensional schematic diagram of the electronic device shown, Figure 6 yes Figure 5 Schematic diagram of the electronic device shown in another perspective. In an embodiment of the present application, the housing assembly 10 includes a first housing 12 and a second housing 14, and the second housing 14 and the first housing 12 are capable of relative movement. Specifically, in this embodiment, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 is capable of sliding relative to the first housing 12. For example, one of the first housing 12 and the second housing 14 can be provided with a slide rail, and the other can slide along the slide rail so that the end of the second housing 14 away from the first housing 12 and the end of the first housing 12 away from the second housing 14 are mounted on or away from each other.

[0048] The second housing 14 can slide relative to the first housing 12 to a first position and a second position. Figure 4 When the second housing 14 is in the first position, the electronic device 100 can obtain a relatively large display area to enhance the user experience of the electronic device 100; when the second housing 14 is in the second position (see Figure 3 ), the electronic device 100 has a relatively small size and is easy to carry. It will be understood that in the embodiments of the present application, the first position, the second position, and similar expressions all refer to the relative positions of the second housing 14 and the first housing 12. For simplicity, expressions such as "the second housing 14 is in the first position" or "when in the first position" refer to the second housing 14 being in the first position relative to the first housing 12, and expressions such as "the second housing 14 is in the second position" or "when in the second position" refer to the second housing 14 being in the second position relative to the first housing 12.

[0049] In the embodiment of the present application, the first position is used as a reference to more clearly determine the position of the end of the second shell 14 away from the first shell 12 and the end of the first shell 12 away from the second shell 14. Figure 4 For example, when the second shell 14 is in the first position, the leftmost side of the electronic device 100 in the width direction is the end of the second shell 14 away from the first shell 12, and the rightmost side of the electronic device 100 in the width direction is the end of the first shell 12 away from the second shell 14.

[0050] In this embodiment, when the second shell 14 is in the first position, the overall width of the electronic device 100 is greater than the width in the second position, so that the width dimension of the exposed flexible screen module 20 is variable. In other words, the size of the electronic device 100 in the width direction is variable. In this embodiment, the external interface of the electronic device 100, such as a data cable jack, a charging cable jack, or a headphone jack, can be set at the end in the width direction. In other embodiments, when the second shell 14 is in the first position, the overall length of the electronic device 100 is greater than the length in the second position, so that the length dimension of the exposed flexible screen module 20 is variable. In other words, the size of the electronic device 100 in the length direction is variable. In this embodiment, the external interface of the electronic device 100, such as a data cable jack, a charging cable jack, or a headphone jack, can be set at the end in the length direction.

[0051] Specifically, see Figure 7 and Figure 8 , Figure 7 yes Figure 3 The main schematic diagram of the electronic device shown, Figure 8 yes Figure 7 A schematic cross-sectional view along the AA direction of an embodiment of an electronic device is shown. The second housing 14 and the first housing 12 can jointly form a receiving space 16. It will be appreciated that the receiving space 16 can change as the second housing 14 and the first housing 12 move relative to each other. The receiving space 16 can be used to accommodate electronic components such as a guide 30, a circuit board, and a battery. The flexible screen module 20 can include a fixed portion 20a and a free portion 20b disposed opposite each other. The fixed portion 20a is disposed in the second housing 14 and fixed relative to the position of the second housing 14. In the second position, the flexible screen module 20 bypasses the guide 30, and the free portion 20b of the flexible screen module 20 is accommodated within the housing assembly 10, so that a portion of the flexible screen module 20 is concealed within the housing assembly 10. The portion of the flexible screen module 20 concealed within the housing assembly 10 is not used for display. In other words, movement of the first housing 12 relative to the second housing 14 can cause at least a portion of the free portion 20b to unfold within the second housing 14, or cause the free portion 20b that has been unfolded within the second housing 14 to retract within the housing assembly 10.

[0052] It is understood that in the embodiments of the present application, the relative fixed positions of two objects means that the two objects cannot produce relative movement under normal circumstances. The two objects that are relatively fixed in position can be physically directly connected or indirectly connected through an intermediate structure. Taking the fixing portion 20a and the second shell 14 as an example, the relative fixed positions of the fixing portion 20a and the second shell 14 can be directly in contact with the fixing portion 20a, such as by using threaded fasteners or clamping to achieve direct fixation of the fixing portion 20a and the second shell 14, or the fixing portion 20a can be indirectly fixed to the second shell 14 through structures such as an adhesive layer, an intermediate connecting plate, etc.

[0053] It can be understood that the fixed portion 20a and the free portion 20b can be distinguished in the following manner: when the second shell 14 is in the second position relative to the first shell 12, the portion of the flexible screen module 20 exposed to the shell assembly 10 is the fixed portion 20a of the flexible screen module 20, and the portion of the flexible screen module 20 housed in the shell assembly 10 can be regarded as the free portion 20b.

[0054] Furthermore, the first shell 12 may include a back cover 142, which covers the free portion 20b of the flexible screen module 20 when in the second position. The back cover 142 may be provided with a light-transmitting area, and the portion of the flexible screen module 20 housed in the shell assembly 10 in the second position may also be used for display, so that the user can view the information displayed by the flexible screen module 20 from the light-transmitting area, thereby expanding the usage scenarios of the electronic device 100. For example, in this embodiment, the electronic device 100 does not need to be provided with a front camera, and a rear-mounted camera module 40 can be used to achieve functions such as selfies and video calls. The light-transmitting area may be made of transparent glass, or it may be formed by an opening in the back cover 142. After the second shell 14 slides to the first position relative to the first shell 12, at least a portion of the flexible screen module 20 housed in the shell assembly 10 is exposed. The exposed flexible screen module 20 can be used for display, so that the electronic device 100 has a relatively large display area to enhance the user experience.

[0055] In this embodiment, the guide member 30 is provided at one end of the second shell 14 away from the first shell 12. When the second shell 14 switches from the second position to the first position relative to the first shell 12, the guide member 30 can guide the flexible screen module 20 to deform and unfold in the second shell 14. The guide member 30 can limit the bending radius of the flexible screen module 20 to an appropriate range to avoid damage to the flexible screen module 20 due to a small bending radius. Of course, the guide member 30 can also prevent the flexible screen module 20 from having an excessively large bending radius, which may cause the thickness of the electronic device 100 to be too large. Figure 8As shown, in some embodiments, the guide member 30 can be a rotating shaft structure with protruding teeth, and the flexible screen module 20 is linked to the guide member 30 by means of engagement or the like. When the second housing 14 slides relative to the first housing 12, the portion of the flexible screen module 20 engaged with the guide member 30 is driven by the guide member 30 to move and expand or retract into the housing assembly 10.

[0056] It is understandable that in other embodiments, the guide member 30 can also be a circular shaft without teeth. In the process of switching the second shell 14 from the second position to the first position, the guide member 30 is used to open the portion of the flexible screen module 20 attached to the guide member 30, so that more flexible screen module 20 is exposed to the outside of the shell assembly 10 and is in a flat state. In this embodiment, the guide member 30 is rotatably arranged on the second shell 14. In the process of gradually unfolding the flexible screen module 20, the guide member 30 can rotate with the movement of the flexible screen module 20 to reduce the resistance encountered by the flexible screen module 20 during the unfolding process and reduce the wear of the guide member 30.

[0057] In other embodiments, the guide member 30 may also be fixed to the second housing 14, and the guide member 30 may have a smooth surface. During the process of unfolding the flexible screen module 20, the guide member 30 can slide in contact with the flexible screen module 20 through its smooth surface. In other words, in this embodiment, the guide member 30 can be integrally formed or welded with the second housing 14, and the guide member 30 can be considered a part of the second housing 14. The free portion 20b of the flexible screen module 20 bypasses the end of the second housing 14 away from the first housing 12 and extends into the housing assembly 10.

[0058] During the process of switching the second housing 14 from the first position to the second position, the flexible screen module 20 can be driven to retract by the guide member 30, that is, the portion of the flexible screen module 20 deployed in the second housing 14 is retracted into the housing assembly 10. Furthermore, in some embodiments, the electronic device 100 may include a drive mechanism 50, which may be disposed in the housing assembly 10. The drive mechanism 50 may be linked to the first housing 12 or the second housing 14 to drive the second housing 14 to move relative to the first housing 12, thereby driving the flexible screen module 20 to deploy or retract.

[0059] See Figure 9 and Figure 10 , Figure 9 yes Figure 6 The main schematic diagram of the electronic device shown, Figure 10 yes Figure 9A schematic cross-sectional view along the BB direction of an embodiment of an electronic device shown. The electronic device 100 may include a tensioning assembly 60, and the free portion 20b of the flexible screen module 20 is linked to the tensioning assembly 60. During the process of switching the second shell 14 from the first position to the second position, the tensioning assembly 60 drives the flexible screen module 20 to reset, thereby causing part of the flexible screen module 20 to be retracted into the shell assembly 10. The tensioning assembly 60 can also be used to apply tensioning force to the free portion 20b during the process of the flexible screen module 20 extending and retracting the shell assembly 10, so that the flexible screen module 20 can be smoothly unfolded to the second shell 14 or retracted into the shell assembly 10. After the flexible screen module 20 is retracted into the shell assembly 10, the electronic device 100 can obtain a relatively small external size to improve the portability of the electronic device 100.

[0060] In some embodiments, the tensioning assembly 60 is disposed in the housing assembly 10 and is connected to the free portion 20b of the flexible screen module 20. The tensioning assembly 60 may include a first elastic member (not shown) and a movable member 61, and the movable member 61 is rotatably connected to the second housing 14. The first elastic member may be a torsion spring, one free end of which is connected to the second housing 14, and the other free end of the torsion spring is connected to the movable member 61, and the torsion spring is sleeved on the movable member 61. During the process of switching the second housing 14 between the first position and the second position relative to the first housing 12, the torsion spring is torsionally deformed and applies tension to the flexible screen module 20 through the movable member 61.

[0061] During the process of the flexible screen module 20 extending from the shell assembly 10, that is, during the process of the second shell 14 switching from the second position to the first position, the free portion 20b of the flexible screen module 20 drives the movable part 61 to rotate relative to the first shell 12 to release the flexible screen module 20 wound on the movable part 61, the first elastic member accumulates elastic potential energy, and the tension applied by the movable part 61 to the flexible screen module 20 acts as resistance, so that the flexible screen module 20 can be smoothly unfolded on the second shell 14; during the process of the flexible screen module 20 retracting into the shell assembly 10, that is, during the process of the second shell 14 switching from the first position to the second position, the first elastic member releases elastic potential energy and drives the movable part 61 to reset, and the movable part 61 applies tension to the flexible screen module 20 as power, so that the flexible screen module 20 can be smoothly retracted into the shell assembly 10, so that the free portion 20b is wound around the movable part 61. In other embodiments, the tensioning assembly 60 can also be connected to the first shell 12.

[0062] In other embodiments, the tensioning assembly 60 may have other structural forms. For example, the movable member 61 and the first elastic member may be omitted, and the tensioning assembly 60 includes an elastic rope connected to the first shell 12 or the second shell 14, so that the elastic rope can be used to apply tension to the flexible screen module 20 during the movement of the first shell 12 relative to the second shell 14. For another example, in an embodiment in which the electronic device 100 includes a driving mechanism 50, the driving mechanism 50 can be connected to the movable member 61 of the tensioning assembly 60. During the process of the flexible screen module 20 extending from the shell assembly 10, the driving mechanism 50 gradually releases the flexible screen module 20 and applies tension to the flexible screen module 20, so that the flexible screen module 20 is smoothly unfolded in the second shell 14; during the process of the flexible screen module 20 retracting into the shell assembly 10, the driving mechanism 50 drives the free portion 20b of the flexible screen module 20 to gradually wind around the movable member 61, so that the flexible screen module 20 is smoothly retracted into the shell assembly 10. In this embodiment, the driving mechanism 50 may be a motor, or a combination of a motor and a gear set.

[0063] It can be understood that in this embodiment, the first position and the second position can be regarded as the two extreme positions of the movement of the second shell 14 relative to the first shell 12. In the first position, the display area of ​​the flexible screen module 20 reaches its maximum state. Under normal circumstances, the second shell 14 can no longer move away from the first shell 12. In the second position, the display area of ​​the flexible screen module 20 reaches its minimum state. Under normal circumstances, the first shell 12 can no longer move toward the first shell 12. The first position and the second position can be achieved by providing a limiting structure on the second shell 14 or the first shell 12 or the guide member 30. For example, a spring can be provided on the second shell 14, and two slots can be provided on the first shell 12. In the first position, the spring engages with one of the slots, thereby achieving the positioning of the second shell 14 and the first shell 12 in the first position; in the second position, the spring engages with the other slot, thereby achieving the positioning of the second shell 14 and the first shell 12 in the second position.

[0064] It is understood that multiple intermediate positions can be provided between the first position and the second position to achieve positioning of the second housing 14 relative to the first housing 12 at multiple positions, and to enable the flexible screen module 20 to have different display areas at different intermediate positions, thereby expanding the use scenarios of the electronic device 100. The multiple intermediate positions can also be achieved by using a limiting structure, for example, by the cooperation of a spring and a slot to achieve positioning of the second housing 14 relative to the first housing 12 at multiple intermediate positions.

[0065] In this embodiment, the electronic device 100 may further include a detection assembly 70, which includes a sensor module 71 and a magnet 73 corresponding to the sensor module 71. The sensor module 71 is fixed relative to the first housing 12 or the second housing 14, and the magnet 73 is fixed relative to the first housing 12, the second housing 14, and one of the remaining two of the free portion 20b. When the first housing 12 moves relative to the second housing 14, the magnet 73 moves relative to the sensor module 71 to detect the length of the free portion 20b extended within the second housing 14.

[0066] That is, the sensor module 71 can not only be used to identify the bracket 200 and enable the electronic device 100 to enter a preset working mode, but can also move relative to the magnet 73 to detect the length of the free portion 20 b unfolded in the second shell 14 .

[0067] Specifically, in some embodiments, the magnet 73 is connected to the first shell 12, the sensor module 71 is connected to the second shell 14, and the sensor module 71 is communicatively connected to the processor. During the movement of the second shell 14 relative to the first shell 12, the magnet 73 moves relative to the sensor module 71, thereby causing the magnitude and direction of the magnetic induction intensity between the magnet 73 and the sensor module 71 to change. This change in the magnetic field can be detected by the sensor module 71, which can be used to determine the position of the magnet 73 relative to the sensor module 71. When the electronic device 100 is provided with a fixed reference zero position, the sensor module 71 can be used to determine the moving distance of the second shell 14 relative to the first shell 12, and then determine the length of the free portion 20b extending out of the shell assembly 10. The processor of the electronic device 100 can adaptively adjust the display interface of the flexible screen module 20 according to the length of the free portion 20b extending out. For example, the display area can be adaptively increased or decreased, or the size of the application icon can be adjusted, or the arrangement of the application icons can be adjusted. In other embodiments, the magnet 73 may be disposed in the second shell 14 , and the sensor module 71 may be disposed in the free portion 20 b of the flexible screen module 20 .

[0068] Continue to refer Figure 11 and Figure 12 , Figure 11 yes Figure 7 The schematic cross-sectional view of another embodiment of the electronic device along the AA direction is shown. Figure 12 yes Figure 9A schematic cross-sectional view along direction BB of another embodiment of an electronic device is shown. The sensor module 71 includes at least two Hall elements 711, arranged along the direction of movement of the first housing 12 relative to the second housing 14. As the second housing 14 moves relative to the first housing 12, the magnet 73 moves relative to the Hall element 711 module. A notable characteristic of the Hall element 711 is that it can output a continuous voltage value when the measured magnetic induction intensity within a certain range continuously changes. For example, when the magnet 73 moves directly above the Hall element 711 in a direction parallel to the Hall element 711, as the magnet 73 gradually approaches and then gradually moves away from the Hall element 711, combined with the characteristics of the Hall element 711 itself (for example, when the magnet 73 is to the left of the center of the Hall element 711, the output value is negative; when the magnet 73 is to the right of the center of the Hall element 711, the output value is positive), it can be considered that the magnetic induction intensity (including magnitude and direction) between the Hall element 711 and the magnet 73 is gradually increasing (or gradually decreasing), and the output value of the Hall element 711 is reflected as a continuous straight line in the rectangular coordinate system, that is, the Hall element 711 can output a continuous voltage. Due to the one-to-one correspondence between voltage and magnetic induction intensity, the relative position of the magnet 73 and the Hall element 711 can be inferred from the output voltage value, and thus the relative position of the first shell 12 and the second shell 14 can be determined.

[0069] In some embodiments, the Hall element 711 is analog. When the magnet 73 moves relative to the Hall element 711 in the manner described above, the Hall element 711 outputs a continuous analog voltage. Figure 13 The output voltage of the analog Hall element 711 and the curve of the magnetic induction intensity in one embodiment are shown. The output voltage of the analog Hall element 711 is converted into a continuous digital signal by an ADC (Analog to Digital Converter), which is then used to determine the relative position of the first shell 12 and the second shell 14. In this embodiment, a plurality of Hall elements 711 can be provided, for example, more than three, and more than three Hall elements 711 can be arranged in an array in the moving direction of the first shell 12 relative to the second shell 14. Further, refer to Figure 12 The sensor module 71 may include a circuit board 713, a plurality of Hall elements 711 may be arranged on the circuit board 713 and electrically connected to the circuit board 713, and the circuit board 713 may be fixed to the first shell 12, or the second shell 14, or the free portion 20b of the flexible screen module 20.

[0070] In other embodiments, the Hall element 711 is digital, and when the magnet 73 moves relative to the Hall element 711 in the above manner, the Hall element 711 outputs a continuous digital signal. For example, Figure 14 and Figure 15 The figure shows the relationship between the output magnetic induction intensity of four digital Hall elements 711 (labeled as S1, S2, S3, S4) arranged in an array and the displacement of the magnet 73. Figure 14 is a curve showing the relationship between the output magnetic induction intensity of the digital Hall element 711 in the X-axis direction and the displacement of the magnet 73. Figure 15 : is the relationship curve between the output magnetic flux density of the digital Hall element 711 in the Z-axis direction and the displacement of the magnet 73. In this embodiment, the output value of the digital Hall element 711 in the Y-axis direction can be ignored, so the relationship curve between the output magnetic flux density in the Y-axis direction and the displacement of the magnet 73 is not shown. The Z-axis direction is parallel to the thickness direction of the electronic device 100, and the X-axis direction is the movement direction of the first shell 12 relative to the second shell 14 ( Figure 12 The Y-axis direction is a direction perpendicular to the Z-axis and the X-axis.

[0071] Since each position of the magnet 73 in the entire stroke corresponds to a magnetic induction intensity, for example, it can be assumed that the magnetic induction intensity detected by the X and Z axes of the first digital Hall element 711 at the initial position (for example, the second position) is the largest, and the magnetic induction intensity detected by other digital Hall elements 711 is smaller, then the magnetic induction intensity value of the initial position is determined. When the magnet 73 moves to any intermediate position (for example, a position between the first position and the second position), for example, the magnet 73 moves to Figure 12 When the magnet 73 is positioned between the two leftmost digital Hall elements 711, the magnetic flux density output value at that position is primarily determined by the output values ​​of the two Hall elements 711 closest to the magnet 73. The magnetic flux density output value at this position is also constant throughout the entire travel of the magnet 73. Therefore, it can be seen that, based on the output curves of the multiple digital Hall elements 711, each position of the magnet 73 throughout the entire travel corresponds to a corresponding magnetic flux density. Figure 16That is, a curve showing the relationship between the estimated displacement of the magnet 73 and the actual displacement of the magnet in one embodiment is shown. The horizontal coordinate of each point on the curve corresponds to the actual displacement of the magnet 73, and the vertical coordinate of each point corresponds to the estimated displacement. It can be seen that when the magnet 73 moves, the output data of the sensor module 71 can determine the position of the magnet 73 in the entire stroke, and correspond to the actual position of the magnet 73, so that the length of the free portion 20b stretched or retracted can be obtained. In this embodiment, a plurality of digital Hall elements 711 can also be provided, for example, more than three, and more than three Hall elements 711 can be arranged in an array in the direction of movement of the first shell 12 relative to the second shell 14. Further, the sensor module 71 may include a circuit board 713, and a plurality of digital Hall elements 711 can be provided on the circuit board 713 and electrically connected to the circuit board 713, and the circuit board 713 can be fixed to the first shell 12, or the second shell 14, or the free portion 20b of the flexible screen module 20.

[0072] In embodiments where the sensor module 71 includes multiple Hall elements 711, adjacent Hall elements 711 can be arranged at equal intervals to provide a more regular output curve for the entire sensor module 71, thereby reducing computational complexity. Of course, in some embodiments, the spacing between adjacent Hall elements 711 can be adaptively adjusted based on simulation results to achieve better detection results.

[0073] Furthermore, in an embodiment where the sensor module 71 includes multiple Hall elements 711, all Hall elements 711 are disposed on the same side of the circuit board 713, and the magnet 73 is disposed toward the Hall element 711. This embodiment facilitates connection between the circuit board 713 and other components and can ensure greater consistency in the output of each Hall element 711, thereby simplifying calculation complexity.

[0074] In some embodiments, the magnet 73 is in a bar shape and has an S pole and an N pole that are oppositely disposed. The S pole and the N pole of the magnet 73 can be arranged perpendicular to the direction of movement of the first shell 12 relative to the second shell 14, and one of the N pole and the S pole faces the sensor module 71. Figure 11 In the illustrated embodiment, the north pole of the magnet 73 is closer to the portion of the second shell 14 that can be used to support the free portion 20b than the south pole. In other words, the north pole and the south pole of the magnet 73 are arranged along the thickness direction of the electronic device 100. In this embodiment, during the movement of the second shell 14 relative to the first shell 12, since a single magnetic pole (south pole or north pole) approaches or moves away from the Hall element 711, the change in the magnetic induction intensity between the Hall element 711 and the magnet 73 is relatively regular, and the detection component 70 can obtain higher detection accuracy, thereby being able to more accurately control the display interface of the flexible screen module 20 to enhance the user experience.

[0075] In other embodiments, the S pole and the N pole may be arranged along the moving direction of the first shell 12 relative to the second shell 14. Figure 11 Taking the housing assembly 10 of the illustrated embodiment as an example, the second housing 14 is located on the left side and the first housing 12 is located on the right side. The north pole can be located at the left end of the magnet 73, and the south pole can be located at the right end of the magnet 73. In other embodiments, the relative positions of the first housing 12 and the second housing 14 can remain unchanged, and the relative positions of the two poles of the magnet 73 can be reversed, that is, the south pole can be located at the left end of the magnet 73, and the north pole can be located at the right end of the magnet 73.

[0076] In an embodiment in which the electronic device 100 includes a drive mechanism 50, the drive mechanism 50 can be communicatively connected to the processor. The processor is configured to control the drive mechanism 50 to drive the second shell 14 to move relative to the first shell 12, and obtain the length of the free portion 20b unfolded in the second shell 14 to adjust the display interface of the flexible screen module 20. In other words, in an embodiment in which the drive mechanism 50 is used to drive the second shell 14 to move relative to the first shell 12, the processor can control the operation of the drive mechanism 50, and then, in combination with the relative motion state feedback by the motion detection component 70 and the displacement data feedback by the detection component 70, the length of the free portion 20b unfolded in the second shell 14 can be accurately controlled, thereby accurately controlling the display interface of the flexible screen module 20. In some embodiments, when a digital Hall element 711 is used to detect displacement, the positioning detection accuracy of the sensor module 71 (which can be a Hall sensor module in this embodiment) can reach 0.05 mm, thereby achieving precise control of the display interface of the flexible screen module 20.

[0077] Of course, in an embodiment in which the electronic device 100 manually moves the first housing 12 relative to the second housing 14, the processor can also accurately determine the length of the free portion 20b unfolded in the second housing 14 based on the relative motion state feedback from the motion detection component 70 and the displacement data feedback from the detection component 70, thereby accurately controlling the display interface of the flexible screen module 20. In other words, the sensor module 71 of the detection component 70 can also achieve high positioning accuracy to achieve precise control of the display interface of the flexible screen module 20.

[0078] Furthermore, in some embodiments, the driving mechanism 50 may include two (see Figure 9), the two driving mechanisms 50 are spaced apart in a direction perpendicular to the movement direction of the second shell 14 relative to the first shell 12, and each driving mechanism 50 is correspondingly provided with a detection component 70. In this embodiment, a dual stepping motor can be used to synchronously control the movement of the second shell 14 relative to the first shell 12, so that the free portion 20b can be smoothly unfolded with the second shell 14 or retracted into the shell assembly 10, so as to avoid the end of the free portion 20b away from the driving mechanism 50 from being deflected during the extension and retraction process, thereby causing damage to the flexible screen module 20. Since each driving mechanism 50 is correspondingly provided with a detection component 70, each driving mechanism 50 can accurately control the movement of the second shell 14 relative to the first shell 12 according to the displacement data fed back by the corresponding detection component 70.

[0079] In the above-mentioned electronic device 100, the first shell 12 can move relative to the second shell 14 to drive the flexible screen module 20 to unfold in the second shell 14 or retract into the shell assembly 10. When the flexible screen module 20 is unfolded in the second shell 14, the electronic device 100 can obtain a relatively large display area to enhance the user experience; after the flexible screen module 20 unfolded in the second shell 14 is retracted into the shell assembly 10, the electronic device 100 can obtain a relatively small external size to have relatively good portability. Since the sensor module 71 and the magnet 73 can be used to detect the length of the free portion 20b unfolded in the second shell 14, the electronic device 100 can adaptively adjust the display size of the flexible screen module 20 according to the length of the free portion 20b unfolded in the second shell 14, thereby enhancing the convenience of use.

[0080] In this embodiment, the bracket 200 is a clamp bracket as an example. The bracket 200 may include a first clamping member 80, a second clamping member 90, and a second elastic member 201 connecting the first clamping member 80 and the second clamping member 90. The second elastic member 201 is used to elastically connect the first clamping member 80 with the first clamping member 80, and the first clamping member 80 can move relative to the second clamping member 90. The electronic device 100 is located between the first clamping member 80 and the second clamping member 90. Since the first clamping member 80 is elastically connected to the first clamping member 80, the bracket 200 can clamp and accommodate electronic devices 100 of different sizes.

[0081] Specifically, the first clamping member 80 may include a first support plate 81 and a first clamping plate 83 extending from a side edge of the first support plate 81. The second clamping member 90 may include a second support plate 91 and a second clamping plate 93 extending from a side edge of the second support plate 91. The first support plate 81 and the second support plate 91 are located on the same plane and are used to support the electronic device 100. The second elastic member 201 is located between the first support plate 81 and the second support plate 91 and connects the first support plate 81 and the second support plate 91. It is used to increase or decrease the support area of ​​the first support plate 81 and the second support plate 91 to adjust the size of the bracket 200.

[0082] The first clamping plate 83 is located on the side of the first support plate 81 away from the second support plate 91, and the second clamping plate 93 is located on the side of the second support plate 91 away from the first support plate 81. The first substrate, the second clamping plate 93, the first support plate 81, and the second support plate 91 are arranged to form a clamping space with adjustable size. The first clamping plate 83 and the second clamping plate 93 are used to clamp the two ends of the bracket 200 so that the bracket 200 can be clamped and accommodated in the clamping space. In this embodiment, the first clamping member 80 is provided corresponding to the first shell 12, and the second clamping member 90 is provided corresponding to the second shell 14, so that the bracket 200 can be provided corresponding to the electronic device 100. In other embodiments, the first clamping member 80 can also be provided corresponding to the second shell 14, and the second clamping member 90 can also be provided corresponding to the first shell 12, and no specific limitation is made here.

[0083] Please refer to Figure 1 、 Figure 2 as well as Figures 17 to 20 , Figure 17 yes Figure 2 The schematic diagram of the main view of the first shell of the bracket in the alignment recognition system shown, Figure 18 yes Figure 17 A schematic front view of another embodiment of the first housing is shown, Figure 19 yes Figure 17 The schematic front view of another embodiment of the first housing shown in FIG. Figure 20 yes Figure 17 The bracket 200 may further include a magnetic module 202 , which may be disposed on the first support plate 81 or the second support plate 91 so that the magnetic module 202 can correspond to the sensor module 71 of the electronic device 100 .

[0084] Specifically, the sensor module 71 can be fixed relative to the first housing 12, and the magnetic module 202 can be disposed on the first support plate 81, so that the magnetic module 202 of the bracket 200 can be disposed correspondingly to the sensor module 71 of the first housing 12. It is understood that when the sensor module 71 senses the magnetic module 202, the electronic device 100 can recognize the bracket 200 and enter a preset operating mode.

[0085] In one embodiment, the Hall sensor can be fixed relative to the second housing 14, and the magnetic module 202 can be disposed on the second support plate 91, so that the magnetic module 202 of the bracket 200 can be disposed correspondingly to the sensor module 71 of the second housing 14. It is understood that when the sensor module 71 senses the magnetic module 202, the electronic device 100 can recognize the bracket 200 and enter a preset operating mode.

[0086] Optionally, the sensor module 71 may include at least one Hall element 711, and the magnetic module 202 may include at least one magnetic part 2021, wherein at least one magnetic part 2021 is arranged in a one-to-one correspondence with at least one Hall element 711, so that the sensor module 71 can identify the magnetic module 202, and then the electronic device 100 can identify the bracket 200 and enter a preset working mode.

[0087] Please refer to Figures 17 to 19 In one embodiment, the magnetic member 2021 may be a magnet, and the magnetic field direction of each magnetic member 2021 is set along a respective preset direction. In other words, the magnetic module 202 includes a plurality of magnetic members 2021 arranged in sequence side by side. Of any two adjacent magnetic members 2021, the magnetic field direction of one magnetic member 2021 is set along a first direction, and the magnetic field direction of the other magnetic member is set along a second direction. The first direction is set at an angle to the second direction or the first direction is parallel to the second direction. This allows the plurality of magnetic members 2021 of the magnetic module 202 to form different magnetic fields, thereby facilitating the electronic device 100 to recognize the bracket 200 and enter a preset operating mode.

[0088] Please refer to Figure 17 and Figure 18 For example, the magnetic module 202 may include a first magnetic member 2021a, a second magnetic member 2021b, and a third magnetic member 2021c, arranged side by side. With the line connecting the edges of the first support plate 81 and the second support plate 91 as a predetermined line L, the magnetic field directions of the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c may be aligned. Specifically, the magnetic field directions of the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c may all be parallel to the predetermined line L. In other words, the magnetic ring direction of the first magnetic member 2021a is parallel to the magnetic field direction of the second magnetic member 2021b, and the magnetic field direction of the second magnetic member 2021b is parallel to the magnetic field square of the third magnetic member 2021c. That is, of any two adjacent magnetic members 2021, the magnetic field direction of one magnetic member 2021 is arranged along the first direction, and the magnetic field direction of the other magnetic member 2021 is arranged along the second direction, with the first direction being parallel to the second direction.

[0089] Please refer to Figure 19, or the angle between it and the preset straight line L can be 30°, 45°, 75°, or 90°, etc., which is not specifically limited here. Alternatively, the magnetic field directions of the first magnetic member 2021a, the second magnetic member 2021b and the third magnetic member 2021c respectively form different angles with the preset straight line L. For example, the magnetic field direction of the first magnetic member 2021a forms an angle of 15° with the preset straight line L, the magnetic field direction of the second magnetic member 2021b forms an angle of 45° with the preset straight line L, and the magnetic field direction of the third magnetic member 2021c forms an angle of 75 degrees with the preset straight line L. In other words, the magnetic ring of the first magnetic member 2021a is set at an angle to the magnetic field direction of the second magnetic member 2021b, and the magnetic field direction of the second magnetic member 2021b is parallel to the magnetic field square of the third magnetic member 2021c. That is, the magnetic field direction of one magnetic member 2021 of any two adjacent magnetic members 2021 is set along the first direction, and the magnetic field direction of the other magnetic member 2021 is set along the second direction, and the first direction and the second direction are set at an angle.

[0090] Furthermore, in a specific embodiment, the magnetic module 202 includes a plurality of magnetic members 2021 arranged in parallel, and the magnetic field directions of two adjacent magnetic members 2021 are arranged in opposite directions. In other words, the first direction is opposite to the second direction.

[0091] Correspondingly, the sensor module 71 may include a first Hall element 711a, a second Hall element 711b, and a third Hall element 711c. The first Hall element 711a, the second Hall element 711b, and the third Hall element 711c correspond to the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c, respectively. The first Hall element 711a, the second Hall element 711b, and the third Hall element 711c can convert the magnetic field direction and magnetic field strength of the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c into corresponding current or voltage, so that the sensor module 71 can identify the magnetic module 202.

[0092] It is understandable that the different magnetic field directions of the magnetic member 2021 in the magnetic module 202 can determine the operating mode of the electronic device 100. For example, when the magnetic field directions of the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c are all parallel to the preset straight line L, the electronic device 100 enters a first preset operating mode, such as flight mode, after recognizing the bracket 200; when the magnetic field direction of the first magnetic member 2021a forms a 15° angle with the preset straight line L, the magnetic field direction of the second magnetic member 2021b forms a 45° angle with the preset straight line L, and the magnetic field direction of the third magnetic member 2021c forms a 75° angle with the preset straight line L, the electronic device 100 enters a second preset operating mode, such as driving mode, after recognizing the bracket 200. No specific limitations are imposed herein.

[0093] Please refer to Figure 20 , Figure 20 yes Figure 17 A schematic front view of a specific embodiment of the first housing is shown. In another embodiment, the sensor module 71 may include multiple Hall elements 711, and the magnetic module 202 may include multiple magnetic parts 2021. The number of Hall elements 711 is an integer multiple of the number of magnetic parts 2021, such as 2 times. That is, each magnetic part 2021 corresponds to two Hall elements 711, so that the sensor module 71 can more accurately identify the magnetic module 202, and thus the electronic device 100 can recognize the bracket 200 and enter the preset working mode.

[0094] Please refer to Figure 21 , Figure 21 yes Figure 17 The front view of another embodiment of the first housing is shown. In yet another embodiment, the magnetic member 2021 is a magnetic coil. When the electronic device 100 is mounted on the bracket 200, the magnetic member 2021 is energized to generate a magnetic field. For example, the magnetic module 202 may include a first magnetic member 2021a, a second magnetic member 2021b, and a third magnetic member 2021c. The first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c each operate at a preset magnetic field strength.

[0095] For example, the first magnetic component 2021a works at a first preset magnetic field strength, the second magnetic component 2021b works at a second preset magnetic field strength, and the third magnetic component 2021c works at a third preset magnetic field strength, wherein the first preset magnetic field strength, the second preset magnetic field strength and the third preset magnetic field strength may be the same or different, and no specific limitation is made here.

[0096] Correspondingly, the sensor module 71 may include a first Hall element 711a, a second Hall element 711b, and a third Hall element 711c. The first Hall element 711a, the second Hall element 711b, and the third Hall element 711c correspond to the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c, respectively. The first Hall element 711a, the second Hall element 711b, and the third Hall element 711c can convert the magnetic field strength of the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c into a corresponding current or voltage, so that the sensor module 71 can identify the magnetic module 202.

[0097] It is understandable that the difference in magnetic field strength of the magnetic member 2021 in the magnetic module 202 can determine the operating mode of the electronic device 100. For example, when the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c all operate at a first preset magnetic field strength, the electronic device 100 enters a first preset operating mode, such as flight mode, after recognizing the bracket 200; when the first magnetic member 2021a operates at a first preset magnetic field strength, the second magnetic member 2021b operates at a second preset magnetic field strength, and the third magnetic member 2021c operates at a third preset magnetic field strength, and the first preset magnetic field strength, the second preset magnetic field strength, and the third preset magnetic field strength are different in magnitude, the electronic device 100 enters a second preset operating mode, such as driving mode, after recognizing the bracket 200, without specific limitation.

[0098] The bracket 200 may further include a proximity sensor 203 for detecting whether the electronic device 100 is mounted on the bracket 200. When the proximity sensor 203 detects that the electronic device 100 is mounted on the bracket 200, the magnetic member 2021 in the bracket 200 is powered on to generate a magnetic field; when the proximity sensor 203 does not detect that the electronic device 100 is mounted on the bracket 200, the magnetic member 2021 in the bracket 200 is powered off.

[0099] Optionally, the plurality of magnetic members 2021 are energized in a predetermined sequence to enable the electronic device 100 to recognize the bracket 200 and enter a corresponding predetermined operating mode. For example, the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c may be energized sequentially, so that the first Hall element 711a, the second Hall element 711b, and the third Hall element 711c can sequentially detect the first magnetic member 2021a, the second magnetic member 2021b, and the third magnetic member 2021c, thereby enabling the electronic device 100 to recognize the bracket 200 and enter a first predetermined operating mode, such as airplane mode. For another example, the first magnetic part 2021a, the third magnetic part 2021c and the second magnetic part 2021b can be energized in sequence, so that the first Hall element 711a, the second Hall element 711b and the third Hall element 711c can detect the first magnetic part 2021a, the second magnetic part 2021b and the third magnetic part 2021c in sequence, thereby enabling the electronic device 100 to recognize the bracket 200 and enter the second preset working mode, such as the driving mode.

[0100] Furthermore, the magnetic component 2021 can also switch the direction of the magnetic field at a preset frequency to facilitate the sensor module 71 to identify the magnetic module 202. For example, the first magnetic component 2021a can switch the direction of the magnetic field at a frequency of 50 Hz, the second magnetic component 2021b can switch the direction of the magnetic field at a frequency of 70 Hz, and the third magnetic component 2021c can switch the direction of the magnetic field at a frequency of 100 Hz. As a result, the Hall sensor can quickly identify the magnetic module 202 and cause the electronic device 100 to enter the corresponding preset operating mode.

[0101] The alignment recognition system 1000 provided in the embodiment of the present application, by setting a sensor module 71 on the electronic device 100 and a magnetic module 202 corresponding to the Hall sensor on the bracket 200, enables the electronic device 100 to recognize the bracket 200 when the electronic device 100 is installed on the bracket 200 and automatically enter the corresponding preset working mode, without the need for user operation and being simple and practical.

[0102] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
