Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a housing assembly and an electronic device. Background Technology

[0002] Some existing electronic devices integrate a display screen and core computing unit into the main unit, with a retractable support stand on the back, and a detachable physical keyboard. When users need to input text, the keyboard can be removed from the main unit for separate use, and the main unit can be supported on a table using the stand.

[0003] However, the stand and keyboard are usually stored in a stacked manner on the back of the main unit. This stacked structure significantly increases the overall thickness of the electronic device when it is stored, affecting its portability. Utility Model Content

[0004] This application provides a housing assembly and an electronic device. By rationally designing the storage positions of the bracket and keyboard on the housing of the electronic device, the overall thickness of the electronic device can be reduced, thereby improving the portability of the electronic device.

[0005] In a first aspect, a housing assembly is provided, the housing assembly comprising: a housing and a support structure;

[0006] The housing has a first surface and a second surface that are arranged opposite to each other along the thickness direction. The first surface is used to mount the display screen of the electronic device, and the second surface is provided with the bracket structure connected to the housing.

[0007] The support structure can rotate relative to the housing to be in a closed state or an unfolded state. When the support structure is in the closed state, it can be stored in a first area on the second surface. When the support structure is unfolded relative to the second surface at a preset angle and is in the unfolded state, it is used to support the housing assembly.

[0008] The second surface also has a second area for accommodating the keyboard, and the second area and the first area are arranged on the second surface along a direction perpendicular to the thickness of the housing.

[0009] The second side of the housing can be provided with a first area and a second area. The first area and the second area can be arranged along the thickness direction perpendicular to the housing. When the keyboard is not needed, it can be stored in the second area. When the keyboard is needed, it can be removed. That is, the second area can be used to store the keyboard of the electronic device. In this way, the keyboard and the bracket structure can be arranged in different areas along the thickness direction perpendicular to the housing.

[0010] It should be noted that the keyboard and support structure can be arranged along the width direction of the housing. In other embodiments, the keyboard and support structure can be arranged along the length direction of the housing. In still other embodiments, the keyboard and support structure can also be arranged along the angle between the width and length directions of the housing. In this way, the arrangement of the keyboard and support structure will not occupy too much space in the thickness direction of the housing.

[0011] In addition, the dimensions of the keyboard and stand structure can be designed according to the size of the display screen so that the edges of the keyboard and stand structure do not protrude beyond the edge of the display screen. In other words, the projection of the keyboard and stand structure can coincide with the projection of the display screen, thereby reducing the impact on the width and length dimensions of the electronic device.

[0012] It should be noted that in some embodiments, the housing of the housing assembly can be installed on the display screen to form a mounting cavity, in which the central processing unit, control mechanism, battery and other structures of the electronic device can be installed; in other embodiments, the housing of the housing assembly can serve as a protective shell. In this case, the electronic device can also include a rear shell, which is connected to the display screen to form a cavity for installing the central processing unit, control mechanism, battery and other structures. In this case, the housing assembly can cover the back side of the rear shell.

[0013] The housing assembly provided in this application embodiment has a support structure on the second side of the housing. When the support structure is unfolded, it can support the housing, thereby supporting the display screen of the electronic device through the housing, so that the display screen can be fixed at a specific angle for user convenience. Arranging the keyboard and support structure in different areas of the housing along the thickness direction perpendicular to the housing can reduce the space occupied in the thickness direction of the housing, that is, it can reduce the overall thickness of the electronic device when the keyboard and support structure are stored in the display screen, thus helping to improve the portability of the electronic device.

[0014] In some embodiments, the display screen can be a foldable display screen, which may include a first screen body and a second screen body rotatably connected to the first screen body. The first screen body and the second screen body can rotate relative to each other to allow the display screen to be folded or unfolded. When the display screen is unfolded, the first screen body and the second screen body are on the same plane. When the display screen is folded, the sides of the first screen body and the second screen body are in contact with each other, and the projections of the first screen body and the second screen body coincide. It is understood that when the display screen is a foldable display screen, the housing can be correspondingly configured as a foldable housing. For example, the housing may include a first main body and a second main body rotatably connected to the first main body. The second main body can rotate relative to the first main body about a first axis to allow the housing to be folded or unfolded. The first main body may be disposed on the back side of the first screen body, the second main body may be disposed on the back side of the second screen body, and both the first region and the second region are disposed on the first main body.

[0015] Both the first and second areas are located on the first main body, that is, the support structure is located on the first main body. The keyboard can be stored in the first main body. When the first and second main bodies are stacked, the support structure and the keyboard can still be arranged along the direction perpendicular to the thickness of the electronic device. This ensures that the support structure and the keyboard do not overlap in the thickness direction of the electronic device. In addition, the keyboard can be stored in the empty area at the edge of the support structure (or the support structure can be set up in the empty area at the edge of the keyboard). This can reduce the impact of the keyboard and support structure on the thickness of the electronic device, thereby helping to improve the portability of the electronic device.

[0016] In some embodiments, the support structure of the housing assembly is detachably connected to the housing. This detachable connection allows for easy replacement of the support structure when it becomes worn.

[0017] In one possible implementation, a first magnetic element is provided inside the support structure, and a second magnetic element is provided inside the housing;

[0018] The first magnetic component is positioned opposite the second magnetic component, and the first magnetic component and the second magnetic component are magnetically attracted to each other to connect the support structure and the housing.

[0019] A first magnetic component is installed inside the bracket structure, and a second magnetic component is installed inside the housing. The magnetic attraction between the first and second magnetic components connects the bracket structure and the housing, ensuring the stability of the connection between them. Furthermore, the first and second magnetic components can be built into the bracket structure and the housing respectively, meaning they are not exposed. This improves the appearance of the bracket structure and the housing, thereby enhancing the overall aesthetics of the electronic device.

[0020] When it is necessary to disassemble the support structure, external force can be used to overcome the magnetic attraction between the first and second magnetic components in order to separate the support structure from the housing.

[0021] In one possible implementation, the support structure includes a support portion, a connecting portion, and a rotating shaft assembly. The support portion and the connecting portion are rotatably connected via the rotating shaft assembly. The support portion is rotatable relative to the connecting portion to allow the support structure to be in the unfolded state or the closed state. When the support structure is in the unfolded state, the support portion supports the housing. The connecting portion is provided with a first magnetic element, the position of which is opposite to the position of a second magnetic element.

[0022] The support and the connecting part are rotatably connected by a rotating shaft assembly. The support can rotate relative to the connecting part, and the connecting part is connected to the shell. Therefore, when the support rotates, the relative position of the support and the shell will change, so that the bracket structure can switch between the unfolded state and the closed state, which can facilitate the use of the bracket structure.

[0023] The rotating shaft assembly includes a base and a rotating component disposed on the base. One end of the rotating component is rotatably connected to the base, and the rotating component is also connected to the support part of the support structure. The base is connected to the connecting part of the support structure. The rotating component can rotate relative to the base to drive the support part of the support structure to rotate relative to the connecting part, so that the support structure can switch between a closed state and an open state.

[0024] The base is provided with a first arc-shaped groove, and the rotating component is provided with a first slider that matches the first arc-shaped groove. The rotating component slides and adapts to the first arc-shaped groove through the first slider. When the first slider slides in the first arc-shaped groove, the rotating component can rotate around the central axis of the first arc-shaped groove. The central axis of the first arc-shaped groove is a virtual axis, and the end of the support part can be located at this virtual axis. In this way, when the rotating component drives the support part to rotate, the distance between the end of the support part and the end of the connecting part changes little, which can reduce the gap between the support part and the connecting part in various states and improve the appearance of the bracket structure.

[0025] In some embodiments, a limiting structure (such as a stepped surface) may be provided in the first arc-shaped groove. The limiting structure can restrict the sliding range of the first slider to reduce the risk of the first slider dislodging from the first arc-shaped groove.

[0026] In some embodiments, the base may also be provided with a second arc-shaped groove, the central axis of which coincides with that of the first arc-shaped groove, and the rotating component is provided with a second slider that matches the second arc-shaped groove, and the rotating component slides and adapts to the second arc-shaped groove through the second slider.

[0027] By setting a second arc-shaped groove that coincides with the central axis of the first arc-shaped groove, the stability of the rotating component can be increased, thereby improving the stability of the support structure during the unfolding and closing process.

[0028] In some embodiments, the pivot assembly further includes a first elastic element connected to both the base and the rotating member. The first elastic element drives the rotating member to rotate, thereby driving the support portion to unfold. By connecting the first elastic element to both the base and the rotating member, the first elastic element can drive the rotating member to rotate relative to the base, providing power for the unfolding of the support structure. Furthermore, when the support portion supports the display screen, the elastic force of the first elastic element can also keep the rotating member and the support portion unfolded, ensuring the stability of the electronic device.

[0029] In some embodiments, under the elastic force of the first elastic member, the included angle between the support and the second surface of the housing can be in the range of 5° to 60°, which allows the display screen to tilt at a specific angle, making it convenient for users to view the images displayed on the display screen.

[0030] In some embodiments, the first elastic element is a torsion spring, which is movably mounted on the base. The rotating shaft assembly also includes a mounting member and a first connecting shaft disposed at one end of the mounting member. The first connecting shaft is connected to the rotating member. The end of the mounting member opposite to the first connecting shaft is slidably connected to the base. The torsion spring is sleeved on the first connecting shaft. One end of the torsion spring abuts against the rotating member, and the other end of the torsion spring abuts against the base through the mounting member. When the torsion spring drives the rotating member to rotate relative to the base, the rotating member can pull the mounting member to move through the first connecting shaft so that the torsion spring can always abut against the rotating member and the mounting member.

[0031] When the rotating component rotates relative to the base under the elastic force of the torsion spring, the rotating component can pull the mounting component to rotate, so that the torsion spring can always resist the rotating component and the mounting component. In this way, the amount of change in the elastic force of the torsion spring on the rotating component can be reduced, so that when the support part supports the display screen, the rotating component can remain extended under the elastic force of the torsion spring.

[0032] In some embodiments, a second connecting shaft is provided at the end of the mounting member opposite to the first connecting shaft, and the base is provided with a sliding groove that matches the second connecting shaft. The mounting member slides and adapts to the sliding groove via the second connecting shaft. When the position of the mounting member changes due to the drive of the rotating member, the second connecting shaft can slide within the sliding groove to adapt to the position change of the mounting member, thereby ensuring that the mounting member always abuts against the torsion spring.

[0033] In one possible implementation, the housing assembly further includes a first elastic element, one end of which contacts the housing and the other end of which is connected to the support portion of the bracket structure. The first elastic element is used to drive the support portion to rotate relative to the housing so that the bracket structure is in the unfolded state.

[0034] The housing assembly also includes a locking structure;

[0035] The locking structure is used to provide a first force to the support structure so that the support structure is in the closed state, and the first force is used to overcome the elastic force of the first elastic element;

[0036] The locking structure is also used to cancel or reduce the first force so that the support structure is in the unfolded state under the elastic force of the first elastic member.

[0037] It should be noted that the first force can be greater than the elastic force of the first elastic element, and the direction of the first force can be opposite to the direction of the elastic force of the first elastic element, so that the first force can overcome the elastic force of the first elastic element and keep the support structure in a closed state.

[0038] The system is equipped with a first elastic element and a locking structure. When the first force of the locking structure disappears, the locking structure is in the unlocked state. At this time, the bracket structure can automatically unfold under the elastic action of the first elastic element. When the locking structure is in the locked state, the first force provided by the locking structure can keep the bracket structure in the closed state. At this time, the electronic device can be easily stored away, thus facilitating the use of the electronic device.

[0039] In some embodiments, when it is necessary to change the support structure from the unfolded state to the closed state, an external force can be used to rotate the support part of the support structure to fit against the shell, and restore the first force of the locking structure so that the locking structure can resist the elastic force of the first elastic element to lock the support structure. At this time, the support structure will not unfold under the elastic force of the first elastic element, and the support structure can remain in the closed state.

[0040] In one possible implementation, the locking structure includes a third magnetic element disposed within the support portion and a fourth magnetic element disposed within the housing.

[0041] The third and fourth magnetic components are magnetically attracted to provide the first force, so that the support structure remains in the closed state.

[0042] The first force decreases or disappears as the adsorption force between the third magnetic element and the fourth magnetic element decreases, so that the support structure can be in the unfolded state under the elastic force of the first elastic element.

[0043] It should be noted that when the adsorption force between the third and fourth magnetic components decreases to the point that the first force is less than the elastic force of the first elastic component, the first elastic component can drive the support part to rotate relative to the shell, so that the support structure is in the unfolded state.

[0044] A third magnetic component is installed inside the support section, and a fourth magnetic component is installed inside the housing. When the third and fourth magnetic components are magnetically attracted, they can provide a first force. At this time, the support section can be attracted to the housing so that the support structure is in a closed state. When the magnetic attraction force of the third and fourth magnetic components decreases, the elastic force of the first elastic component can overcome the force between the third and fourth magnetic components to unfold the support structure.

[0045] In some embodiments, when it is necessary to switch the support structure from the unfolded state to the closed state, the support part can be manually rotated so that the support part fits into the shell, and the first force provided by the third and fourth magnetic elements of the locking structure is restored. The locking structure can overcome the elastic force of the first elastic element so that the support structure can remain in the closed state.

[0046] In one possible implementation, at least one of the third and fourth magnetic elements can move along a direction perpendicular to the thickness of the housing, such that the positions of the third and fourth magnetic elements are opposite or offset; when opposite, they are used for magnetic attraction to provide the first force; when offset, the first force is reduced or disappears; or,

[0047] At least one of the third and fourth magnetic elements can rotate along the axis of the magnetic element so that the different magnetic poles of the third and fourth magnetic elements are opposite to each other or misaligned; when the different magnetic poles are opposite to each other, they are used for magnetic attraction to provide the first force; when the different magnetic poles are misaligned, the first force is reduced or disappears.

[0048] It should be noted that at least one of the third and fourth magnetic components can move along a direction perpendicular to the thickness of the shell. This movement can be either the third magnetic component moving along the same direction, or the fourth magnetic component moving along the same direction, or both the third and fourth magnetic components moving along directions perpendicular to the thickness of the shell. Regardless of which magnetic component moves, a relative displacement will occur between the third and fourth magnetic components, causing a change in their positions and thus altering the magnitude of the initial force generated between them. Furthermore, movement along the direction perpendicular to the thickness of the shell can be linear movement in a plane perpendicular to the thickness of the shell, or it can be oscillation in a plane perpendicular to the thickness of the shell.

[0049] By driving at least one of the third and fourth magnetic components to move to change their relative positions, the magnetic attraction between the third and fourth magnetic components can be weakened to reduce the first force. This allows the unlocking and locking structure to be unlocked, so that the support structure can be deployed under the elastic force of the first elastic component.

[0050] In some embodiments, the third magnetic element includes a first magnetic pole and a second magnetic pole, and the fourth magnetic element includes a third magnetic pole and a fourth magnetic pole. The first magnetic pole can magnetically attract the third magnetic pole, and the second magnetic pole can magnetically attract the fourth magnetic pole to provide a first force. When the third and fourth magnetic elements are misaligned, the first magnetic pole can be positioned opposite the fourth magnetic pole to generate a magnetic repulsion force, and the second magnetic pole can be positioned opposite the third magnetic pole to generate a magnetic repulsion force. At this time, the first force provided by the third and fourth magnetic elements disappears, and the magnetic repulsion force generated between the third and fourth magnetic elements can provide a second force. The second force can drive the support part to rotate relative to the shell. At this time, the support structure can be deployed under the combined action of the second force and the elastic force of the first elastic element. It should be noted that during the deployment of the support structure, the distance between the third and fourth magnetic elements gradually increases, and the second force provided by the third and fourth magnetic elements due to magnetic repulsion gradually decreases.

[0051] It should be noted that at least one of the third and fourth magnetic components can rotate along the axis of the magnetic component. This can be either the third magnetic component rotating along its own axis, or the fourth magnetic component rotating along its own axis, or both the third and fourth magnetic components rotating along their own axes. However, regardless of which magnetic component rotates, a relative change in position will occur between the third and fourth magnetic components, thereby altering the magnitude of the initial force generated between them.

[0052] At least one of the third and fourth magnetic components can rotate along the axis of the magnetic component, which reduces the space occupied by the corresponding magnetic component when adjusting its position, thus helping to improve the compactness of the structure and reduce the overall size of the electronic device.

[0053] In this embodiment, the fourth magnetic element can rotate along its own axis.

[0054] In one possible implementation, a driving structure is provided inside the housing, the driving structure being connected to the third magnetic element and / or the fourth magnetic element, for driving the corresponding magnetic element to move.

[0055] A drive structure is installed inside the housing, which can drive the fourth magnetic component to move. This reduces the difficulty of adjusting the position of the fourth magnetic component, thus facilitating the unfolding of the support structure.

[0056] In one possible implementation, the driving structure includes an SMA assembly for heating and contracting upon energization to move the third magnetic element and / or the fourth magnetic element; or,

[0057] The drive structure includes a motor, the output shaft of which is connected to the corresponding magnetic component to drive the third magnetic component and / or the fourth magnetic component to move.

[0058] An SMA (Shape Memory Alloy) assembly may include an SMA actuator and an SMA component. The SMA actuator can be connected to the control mechanism of an electronic device, and the SMA component can be connected to a fourth magnetic component. The SMA component exhibits shape memory effect; after plastic deformation and fixation under certain conditions, it can recover its initial shape before deformation when external conditions (such as temperature and stress) change. At room temperature (e.g., 25°C), the SMA component can be in a first state. When the SMA actuator applies current to the SMA component, raising its temperature to a certain level (e.g., 85°C~95°C), the SMA component deforms to a second state. When the SMA actuator de-energizes, allowing the SMA component's temperature to return to room temperature (e.g., 25°C), the SMA component returns to its first state. Common SMA components include nickel-titanium shape memory alloys, copper-based shape memory alloys, and iron-based shape memory alloys. In some embodiments, the temperature of the SMA component after being heated by the SMA actuator applying current may not exceed 120°C.

[0059] Because the SMA component has shape recovery characteristics, it can undergo plastic deformation under certain conditions, and automatically return to its initial shape when external conditions (such as temperature, stress, etc.) change. This characteristic enables it to achieve reciprocating driving action. That is, when the conditions (such as temperature, etc.) change, the SMA component can deform to drive the fourth magnetic component to move, so that the fourth magnetic component and the third magnetic component are misaligned. At this time, the locking structure cancels the first force to unlock. When the conditions return to normal, the SMA component can drive the fourth magnetic component to reset during the shape recovery process. At this time, when the support part is rotated to fit with the second surface of the shell, the locking structure can restore the first force and keep the support structure in a closed state.

[0060] It is understood that the deformation shape of the SMA component can affect the movement direction of the fourth magnetic component. For example, the SMA component can drive the fourth magnetic component to move linearly, and the deformation generated by the SMA component can drive the fourth magnetic component to swing, and the swing direction of the fourth magnetic component is parallel to the plane perpendicular to the thickness direction of the shell.

[0061] In some embodiments, after the SMA driver is powered on and deforms the SMA component, the SMA driver can automatically power off after a preset time (such as 2 seconds, 3 seconds, etc.). In other embodiments, a sensor connected to the SMA driver can be installed in the housing to trigger the SMA driver to power off.

[0062] In some embodiments, an insulating layer can be provided on the surface of the SMA component. In this way, when the SMA component comes into contact with other components in the electronic device, the insulating layer can insulate the SMA component from the corresponding components, thereby reducing the risk of short circuits in the electronic device and improving the stability of the electronic device.

[0063] In some embodiments, the drive structure includes a motor, the output shaft of which is connected to a corresponding magnetic element to drive the corresponding magnetic element to move. For example, the output shaft of the motor may be connected to a fourth magnetic element to drive the fourth magnetic element to move relative to the third magnetic element.

[0064] In some embodiments, the motor can be a linear motor, in which case the motor's output shaft can move linearly relative to the motor body, thereby driving the fourth magnetic component to move linearly. In other embodiments, the motor's output shaft can rotate, in which case a gear and rack assembly can be used to convert the rotational motion of the output shaft into the linear movement of the fourth magnetic component.

[0065] By using a motor to drive the fourth magnetic component, the position of the fourth magnetic component can be easily adjusted, changing the magnetic attraction force between the fourth and third magnetic components. This allows the locking structure to generate a first force to keep the support structure in a closed state, or to cancel the first force to unfold the support structure. Furthermore, when the support part is rotated to fit against the housing, the motor can also drive the fourth magnetic component to reset, allowing the locking structure to restore the first force and keep the support structure in a closed state.

[0066] In some embodiments, after the motor drives the fourth magnetic component to move, the motor can automatically reverse after a preset time (such as 2 seconds, 3 seconds, etc.) so that its output shaft can drive the fourth magnetic component to reset. In other embodiments, a sensor connected to the motor can be installed in the housing to trigger the motor so that the motor's output shaft reverses.

[0067] In some embodiments, the drive structure may further include a carrier, and the fourth magnetic element may be installed in the slot of the carrier. The SMA component or motor of the drive structure may be connected to the carrier, that is, the SMA component or motor may be connected to the fourth magnetic element through the carrier to drive the fourth magnetic element to move, thus facilitating installation.

[0068] In one possible implementation, the drive structure further includes a second elastic element, one end of which is connected to the housing, and the other end of which is connected to the third magnetic element and / or the fourth magnetic element, so that when the force that drives the third magnetic element and the fourth magnetic element to misalign disappears, the second elastic element can drive the third magnetic element and / or the fourth magnetic element to reset.

[0069] When the driving structure is connected to the third magnetic component to drive its movement, the end of the second elastic element away from the housing can be connected to the third magnetic component to drive it to reset. Similarly, when the driving structure is connected to the fourth magnetic component to drive its movement, the end of the second elastic element away from the housing can be connected to the fourth magnetic component to drive it to reset. Furthermore, the elastic force of the second elastic element can be less than the force exerted by the driving structure, allowing the driving structure to overcome the elastic force of the second elastic element and drive the corresponding magnetic component to move.

[0070] The second elastic element is connected to the housing and the third and / or fourth magnetic elements respectively. When the force applied to the third and / or fourth magnetic elements by the driving structure disappears, the elastic force of the second elastic element can drive the third and / or fourth magnetic elements to reset, so that the locking structure can provide the first force again and realize the reuse of the locking structure.

[0071] In this embodiment, the driving structure is connected to the fourth magnetic element to drive the fourth magnetic element to move, and the second elastic element can be connected to the housing and the fourth magnetic element respectively.

[0072] In some embodiments, the second elastic element may be a spring.

[0073] In one possible implementation, at least one of the third and fourth magnetic elements is an electromagnet, the magnetic pole direction of which is variable or the magnetic field of which is reduced, so as to reduce the attraction force between the third and fourth magnetic elements.

[0074] It should be noted that the third magnetic component can be set as an electromagnet, in which case the fourth magnetic component can be set as a permanent magnet; or the fourth magnetic component can be set as an electromagnet, in which case the third magnetic component can be set as a permanent magnet; or both the third and fourth magnetic components can be set as electromagnets.

[0075] By using an electromagnet as at least one of the third and fourth magnetic components, the attraction force between the third and fourth magnetic components can be reduced by changing the direction of the electromagnet's magnetic poles or the strength of its magnetic field. In this way, it is not necessary to move or rotate the third and fourth magnetic components, which can reduce the space reserved for changes in the position of the third and fourth magnetic components, thereby improving the compactness of the electronic device structure and helping to reduce the overall size of the electronic device.

[0076] In some embodiments, the electromagnet can be connected to the control mechanism of an electronic device, which can control the direction of the electromagnet's magnetic poles or change the strength of the electromagnet's magnetic field.

[0077] In some embodiments, the attraction between the third and fourth magnetic components can be reduced simply by weakening the magnetic field of the electromagnet, thereby canceling the first force of the locking structure. In other embodiments, the direction of the magnetic poles of the electromagnet can be changed so that the third and fourth magnetic components can change from magnetic attraction to magnetic repulsion. In this case, the magnetic repulsion between the third and fourth magnetic components can provide a second force to assist in the deployment of the support structure.

[0078] In one possible implementation, the locking structure includes:

[0079] A first fastening element is disposed on the housing;

[0080] A second fastening member is disposed on the support portion, and the first fastening member and the second fastening member can be fastened together to provide the first force;

[0081] The first and second fastening members move relative to each other to separate them, thereby canceling the application of the first force to the support structure.

[0082] It should be noted that one of the first fastening component and the second fastening component can be a snap fastener, and the other of the first fastening component and the second fastening component can be a fastening position.

[0083] By setting a first fastening component and a second fastening component, the bracket structure can be kept in a closed state when the first fastening component and the second fastening component are fastened together.

[0084] In a second aspect, an electronic device is provided, including a display screen, wherein a housing assembly is disposed on the back side of the display screen, and the housing assembly is the aforementioned housing assembly.

[0085] In some embodiments, the housing assembly can be integrated with the display screen, and the central processing unit, battery, and other structures of the electronic device can be installed in the mounting cavity formed by the housing assembly and the display screen. In other embodiments, the housing assembly is an independent structure, and the electronic device can also include a rear shell, which is installed on the back side of the display screen and forms a cavity for installing the central processing unit, battery, and other structures. In this case, the housing assembly can be installed on the back side of the rear shell as a protective shell.

[0086] In addition, during normal use, the front side of the display screen faces the user, and the back side of the display screen faces away from the user. The front side of the display screen can display information such as images. In some embodiments, the display screen can have a touch function, allowing the user to perform touch operations on the display screen to interact with the electronic device.

[0087] In some embodiments, the electronic device also includes a keyboard. The keyboard and display screen can be communicatively connected to the central processing unit (CPU) of the electronic device, enabling the display screen to display information entered by the user via the keyboard in real time. The communication connection can be achieved via wired means such as wires, or wireless means such as Bluetooth, Wi-Fi, or mobile networks. For example, the keyboard can be connected to the CPU via a signal cable, and the CPU can also be connected to the display screen via a signal cable. Of course, the keyboard and CPU, as well as the CPU and display screen 100, can also be wirelessly connected via means such as Bluetooth, Wi-Fi, or mobile networks to achieve signal transmission between them.

[0088] In one possible implementation, the electronic device further includes a control mechanism connected to a locking structure of the housing assembly to control the locking structure to unlock or lock. When the locking structure is locked, the locking structure provides a first force to a support structure of the housing assembly. When the locking structure is unlocked, the locking structure cancels the first force provided to the support structure.

[0089] A control mechanism is installed inside the electronic device. This mechanism can automatically control the locking structure of the housing component to unlock or lock, thus facilitating the use of the bracket structure.

[0090] For example, the control mechanism can control the locking structure to unlock or lock through the drive structure. For instance, the control mechanism can be connected to the SMA driver or motor of the drive structure to control the position of the fourth magnetic element. Or, when the fourth magnetic element is an electromagnet, the control mechanism can control the strength of the magnetic field and the direction of the magnetic poles of the fourth magnetic element by controlling the magnitude and direction of the current supplied to the fourth magnetic element.

[0091] In one possible implementation, the electronic device further includes a first sensor connected to the control mechanism, the first sensor being configured to send a first control signal to the control mechanism upon detecting information indicating that the keyboard of the electronic device has been disassembled, the first control signal being configured to trigger the control mechanism to unlock the locking structure.

[0092] By setting a first sensor, the electronic device can automatically control the stand structure to unfold when the keyboard is removed from the housing, thus making it more convenient for the user.

[0093] The first sensor can be a photoelectric sensor. When the keyboard is stored in the second area of ​​the housing, the first sensor can be blocked by the keyboard. At this time, the first sensor cannot receive light signals and will not send the first control signal to the control mechanism. When the keyboard is removed from the housing, the first sensor is not blocked by the keyboard. At this time, the first sensor can receive light signals and be triggered to send the first control signal to the control mechanism, so that the electronic device can automatically control the bracket structure to unfold when the keyboard is removed. In other embodiments, the first sensor can be a Hall sensor. A Hall sensing element can be set at the position of the keyboard corresponding to the Hall sensor. When the keyboard is stored in the second area of ​​the housing, the Hall sensor can sense the Hall sensing element but is not triggered. When the keyboard is removed from the housing, the Hall sensor cannot detect the Hall sensing element and is triggered, thereby sending the first control signal to the control mechanism. In other embodiments, the first sensor can also be an integrated circuit (IC) sensor. In this case, an IC chip can be set on the keyboard. In addition, the first sensor can also be a sensor of the type of infrared sensor, etc.

[0094] In one possible implementation, the electronic device further includes a second sensor disposed within the housing, the second sensor being used to detect a user's trigger operation on a target area of ​​the display screen, and to send the trigger operation to the control mechanism, the control mechanism being used to control the locking structure to unlock when the trigger operation matches a preset trigger operation.

[0095] By using a second sensor to detect user trigger operations, the electronic device can unfold the support structure according to the user's instructions, thus facilitating its use. For example, the user can set a specific touch gesture (such as tapping a target area) to trigger the second sensor. After receiving the trigger operation, the second sensor can send a trigger operation to the control mechanism, allowing the control mechanism to unlock the locking structure when the trigger operation matches a preset trigger operation.

[0096] In one possible implementation, the electronic device has a button that, when pressed, sends a second control signal to a control mechanism, which triggers the control mechanism to unlock the locking mechanism.

[0097] In this embodiment, the button can be a button specifically designed to trigger the control mechanism, or it can be a volume button, power button, or other button of an electronic device. It is triggered by setting a specific pressing frequency or pressing combination (such as double-clicking the volume button) to send a second control signal to the control mechanism.

[0098] Users can trigger the second sensor by pressing a button, so that the control mechanism can unlock the locking structure after receiving the second control signal sent by the button, thus enabling the bracket structure to unfold, which makes it convenient to use.

[0099] For example, users can set specific touch gestures (such as tapping a specific area of ​​the sensing zone) to trigger the second sensor. After receiving the trigger operation information sent by the button, the second sensor can send second control information to the control mechanism, thereby unlocking the locking structure and enabling the bracket structure to unfold. This makes it convenient to use. Attached Figure Description

[0125] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0126] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0127] In the description of this application, it should be understood that the terms "upper", "lower", "side", "front", "rear", etc., indicate the orientation or positional relationship based on the installation orientation or positional relationship, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0128] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0129] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0130] With the rapid development of mobile communication technology and the widespread adoption of smart terminals, portable electronic devices such as mobile phones and tablets have become indispensable tools in people's daily lives. Users are placing increasingly higher demands on the portability, ease of use, and functional integration of electronic devices.

[0131] Existing electronic devices, such as tablets, have made significant design efforts to meet diverse user needs. Some electronic devices employ the following structural design: the main unit integrates a display screen and core computing unit, while the back features a retractable support stand and a detachable physical keyboard. When users need to input text, the keyboard can be removed from the main unit for separate use, and the stand supports the main unit on a table.

[0132] While this design improves the flexibility of electronic devices to some extent, when the device is stored, the stand and keyboard are usually stacked on the back of the main unit. This stacked structure significantly increases the overall thickness of the electronic device, affecting its portability.

[0133] Based on this, embodiments of this application provide a housing assembly and an electronic device. By rationally designing the storage positions of the bracket and keyboard on the housing of the electronic device, the overall thickness of the electronic device is reduced, thereby improving the portability of the electronic device.

[0134] This application first provides an electronic device, which may be, for example, a mobile phone, tablet computer, laptop computer, television set, in-vehicle equipment, wearable device, personal digital assistant (PDA), point of sale (POS), camera, video surveillance equipment, or other electronic products with photography or video recording functions. The mobile phone may be, for example, a conventional candybar phone or a foldable phone, such as a small vertical folding phone, a horizontally folding phone, or a horizontally folding phone. Wearable devices may be, for example, smart bracelets, smartwatches, wireless headphones, augmented reality (AR) glasses, AR headsets, virtual reality (VR) glasses, or VR headsets.

[0135] The embodiments of this application will now be described using a tablet computer as an example.

[0136] Figure 1 This is a schematic diagram of the structure of the electronic device provided in an embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the electronic device from another perspective. (Refer to...) Figure 1 and Figure 2The electronic device provided in this application includes a display screen 100 and a housing assembly 300 disposed on the back side of the display screen 100. In some embodiments, the housing assembly 300 can be integrated with the display screen 100, and the central processing unit, battery and other structures of the electronic device can be installed in the mounting cavity formed by the housing assembly 300 and the display screen 100. In other embodiments, the housing assembly 300 is an independent structure, and the electronic device may also include a rear shell, which is installed on the back side of the display screen 100 and surrounds the display screen 100 to form a cavity for installing the central processing unit, battery and other structures. In this case, the housing assembly 300 can be installed on the back side of the rear shell as a protective shell.

[0137] In addition, during normal use, the front side of the display screen 100 faces the user, and the back side of the display screen 100 faces away from the user. The front side of the display screen 100 can display information such as images. In some embodiments, the display screen 100 can have a touch function, and the user can perform touch operations on the display screen 100 to achieve interaction with the electronic device.

[0138] In some embodiments, the electronic device further includes a keyboard 200. The keyboard 200 and the display screen 100 can be communicatively connected to the central processing unit (CPU) of the electronic device, enabling the display screen 100 to display information input by the user via the keyboard 200 in real time. The communication connection can be achieved via wired means such as wires, or wireless means such as Bluetooth, Wi-Fi, or mobile networks. For example, the keyboard 200 can be connected to the CPU via a signal cable, and the CPU can also be connected to the display screen 100 via a signal cable. Of course, the keyboard 200 and the CPU, as well as the CPU and the display screen 100, can also be wirelessly connected via means such as Bluetooth, Wi-Fi, or mobile networks to achieve signal transmission between them.

[0139] The embodiments of this application mainly involve structural improvements to the housing assembly 300. The structure of the housing assembly 300 will be described in detail below with reference to the accompanying drawings.

[0140] Reference Figure 1 and Figure 2 The housing assembly 300 provided in this application embodiment includes a housing 1 and a support structure 2. The housing 1 has a first surface and a second surface disposed opposite to each other along its thickness direction. The first surface is used to mount a display screen 100 of an electronic device, and the second surface is provided with the support structure 2 connected to the housing 1. The support structure 2 is rotatable relative to the housing 1 to be in a closed or unfolded state. (Refer to...) Figure 2 The support structure 2 is in a closed state and can be stored in the first area 101 on the second surface, as shown in the reference. Figure 1When the support structure 2 is in the unfolded state relative to the second surface at a preset angle, it is used to support the housing assembly 300; the second surface also has a second area for accommodating the keyboard 200, and the second area and the first area are arranged on the second surface of the housing along the direction perpendicular to the thickness of the housing 1.

[0141] Figure 3 This is a front view schematic diagram of the housing 1 provided in an embodiment of this application. (Refer to...) Figure 1 and Figure 3 The second side of the housing 1 can be provided with a first region 101 and a second region 102. The first region 101 and the second region 102 can be arranged along the thickness direction perpendicular to the housing 1. When the keyboard 200 is not needed, the keyboard 200 can be stored in the second region 102. When the keyboard 200 is needed, the keyboard 200 can be removed. That is, the second region 102 can be used to store the keyboard 200 of the electronic device. In this way, the keyboard 200 and the bracket structure 2 can be arranged in different regions along the thickness direction perpendicular to the housing 1.

[0142] It should be noted that the keyboard 200 and the support structure 2 can be arranged along the width direction of the housing 1. In some embodiments, the keyboard 200 and the support structure 2 can be arranged along the length direction of the housing 1. In still some embodiments, the keyboard 200 and the support structure 2 can also be arranged along the direction of the angle between the width direction and the length direction of the housing 1. In this way, the arrangement of the keyboard 200 and the support structure 2 will not occupy too much space in the thickness direction of the housing 1.

[0143] In addition, refer to Figure 2 The dimensions of the keyboard 200 and the support structure 2 can be designed according to the dimensions of the display screen 100 so that the edges of the keyboard 200 and the support structure 2 do not protrude beyond the edges of the display screen 100. In other words, the projection of the keyboard 200 and the support structure 2 can coincide with the projection of the display screen 100, thereby reducing the impact on the width and length dimensions of the electronic device.

[0144] It should be noted that in some embodiments, after the housing 1 of the housing assembly 300 is installed on the display screen 100, it can form a mounting cavity with the display screen 100, and the central processing unit, control mechanism, battery and other structures of the electronic device can be installed in the mounting cavity; in other embodiments, the housing 1 of the housing assembly 300 can serve as a protective shell. In this case, the electronic device can also include a rear shell, which is connected to the display screen 100 to form a cavity for installing the central processing unit, control mechanism, battery and other structures. In this case, the housing assembly 300 can cover the back side of the rear shell.

[0145] The housing assembly 300 provided in this application embodiment has a support structure 2 provided on the second side of the housing 1. When the support structure 2 is unfolded, it can support the housing 1, thereby supporting the display screen 100 of the electronic device through the housing 1, so that the display screen 100 can be fixed at a specific angle for user convenience. Arranging the keyboard 200 and the support structure 2 in different areas of the housing 1 along the thickness direction perpendicular to the housing 1 can reduce the space occupied in the thickness direction of the housing 1, that is, it can reduce the overall thickness of the electronic device when the keyboard 200 and the support structure 2 are stored in the display screen 100, thus helping to improve the portability of the electronic device.

[0146] In some embodiments, the display screen 100 may be a foldable display screen, see reference Figure 1 and Figure 2 The display screen 100 may include a first screen body 1001 and a second screen body 1002 rotatably connected to the first screen body 1001. The first screen body 1001 and the second screen body 1002 may rotate relative to each other to allow the display screen 100 to be stacked or unfolded. (Refer to...) Figure 1 When the display screen 100 is unfolded, the first screen 1001 and the second screen 1002 are on the same plane. When the display screen 100 is folded, the sides of the first screen 1001 and the second screen 1002 are in contact with each other, and the projections of the first screen 1001 and the second screen 1002 overlap. It can be understood that when the display screen 100 is a foldable display screen, the housing 1 can be correspondingly configured as a foldable housing. For example, refer to... Figure 1 and Figure 3 The housing 1 may include a first body 11 and a second body 12 rotatably connected to the first body 11. The second body 12 may rotate relative to the first body 11 about a first axis 103 so that the housing 1 may be folded or unfolded. The first body 11 may be disposed on the back side of the first screen 1001, and the second body 12 may be disposed on the back side of the second screen 1002. The first region 101 and the second region 102 are both disposed on the first body 11.

[0147] The first area 101 and the second area 102 are both located on the first main body 11, that is, the support structure 2 is located on the first main body 11. The keyboard 200 can be stored in the first main body 11. When the first main body 11 and the second main body 12 are stacked, the support structure 2 and the keyboard 200 can still be arranged along the direction perpendicular to the thickness of the electronic device. That is, it can be ensured that the support structure 2 and the keyboard 200 do not overlap in the thickness direction of the electronic device. In addition, the keyboard can be stored in the empty area at the edge of the support structure 2 (or the support structure 2 can be set in the empty area at the edge of the keyboard 200). This can reduce the impact of the keyboard 200 and the support structure 2 on the thickness of the electronic device, thereby helping to improve the portability of the electronic device.

[0148] In some embodiments, the support structure 2 of the housing assembly 300 is detachably connected to the housing 1. This detachable connection allows for easy replacement of the support structure 2 when it becomes worn.

[0149] Figure 4 This is a schematic diagram of the structure of an electronic device provided in another embodiment of this application. (Refer to...) Figure 4 The bracket structure 2 is provided with a first magnetic element 24, and the housing 1 is provided with a second magnetic element 13. The positions of the first magnetic element 24 and the second magnetic element 13 are opposite to each other. The first magnetic element 24 and the second magnetic element 13 are magnetically attracted to each other so that the bracket structure 2 and the housing 1 are connected.

[0150] A first magnetic element 24 is provided inside the bracket structure 2, and a second magnetic element 13 is provided inside the housing 1. The magnetic attraction between the first magnetic element 24 and the second magnetic element 13 is used to connect the bracket structure 2 and the housing 1, which can ensure the connection stability between the bracket structure 2 and the housing 1. In addition, the first magnetic element 24 and the second magnetic element 13 can be built into the inside of the bracket structure 2 and the housing 1 respectively, that is, the first magnetic element 24 and the second magnetic element 13 can be concealed. In this way, the appearance of the bracket structure 2 and the housing 1 can be improved, thereby improving the appearance of the electronic device.

[0151] When it is necessary to disassemble the bracket structure 2, external force can be used to overcome the magnetic attraction between the first magnetic element 24 and the second magnetic element 13 to separate the bracket structure 2 from the housing 1.

[0152] In some embodiments, the support structure 2 may contain multiple first magnetic elements 24 arranged sequentially. In this case, the housing 1 may contain multiple second magnetic elements 13, with each second magnetic element corresponding to one of the first magnetic elements 24. Alternatively, the housing 1 may contain only one second magnetic element 13. In this case, the size of the second magnetic element 13 may be slightly larger so that it can magnetically attract the multiple first magnetic elements 24. In other embodiments, the support structure 2 may contain one first magnetic element 24, while the housing 1 contains multiple second magnetic elements 13. In this case, the size of the first magnetic element 24 may be slightly larger so that it can magnetically attract the multiple second magnetic elements 13.

[0153] Reference Figure 1 , Figure 2 and Figure 4The support structure 2 includes a support part 23, a connecting part 21, and a rotating shaft assembly 22. The support part 23 and the connecting part 21 are rotatably connected by the rotating shaft assembly 22. The support part 23 can rotate relative to the connecting part 21 so that the support structure 2 is in an unfolded state or a closed state. When the support structure is in the unfolded state, the support part 23 is used to support the housing 1. The connecting part 21 is provided with a first magnetic element 24. The position of the first magnetic element 24 is opposite to the position of the second magnetic element 13 provided on the housing 1.

[0154] The support part 23 and the connecting part 21 are rotatably connected by the rotating shaft assembly 22. The support part 23 can rotate relative to the connecting part 21, and the connecting part 21 is connected to the housing 1. When the support part 23 rotates, the relative position of the support part 23 and the housing 1 will change, so that the bracket structure 2 can switch between the unfolded state and the closed state, which can facilitate the use of the bracket structure 2.

[0155] Figure 5 This is a schematic diagram of the rotating shaft assembly 22 provided in an embodiment of this application from one perspective; Figure 6 yes Figure 5 Another view of the structure of the rotating shaft assembly 22 shown; Figure 7 yes Figure 5 The schematic diagram of the rotating shaft assembly 22 shown (in unfolded state) is shown. Figure 8 yes Figure 7 The schematic diagram of the rotating shaft assembly 22 shown (with the rotating component 222 hidden); Figure 9 yes Figure 5 The schematic diagram of the rotating shaft assembly 22 shown (closed state) is shown. Figure 10 yes Figure 9 The schematic diagram of the rotating shaft assembly 22 shown (with the rotating component 222 hidden).

[0156] Reference Figure 5 and Figure 6 The rotating shaft assembly 22 includes a base 221 and a rotating member 222 disposed on the base 221. One end of the rotating member 222 is rotatably connected to the base 221, and the rotating member 222 is also connected to the support portion 23 of the bracket structure 2. The base 221 is connected to the connecting portion 21 of the bracket structure 2. (Refer to...) Figures 7 to 10 The rotating component 222 can rotate relative to the base 221 to drive the support part 23 of the bracket structure 2 to rotate relative to the connecting part 21, so that the bracket structure 2 can switch between the closed state and the unfolded state.

[0157] Figure 11 This is a schematic diagram of the structure of the base 221 provided in an embodiment of this application. (Refer to...) Figures 9 to 11The base 221 is provided with a first arc-shaped groove 2211, and the rotating component 222 is provided with a first slider 2221 that matches the first arc-shaped groove 2211. The rotating component 222 slides and adapts to the first arc-shaped groove 2211 through the first slider 2221. When the first slider 2221 slides within the first arc-shaped groove 2211, the rotating component 222 can rotate around the central axis of the first arc-shaped groove 2211 (i.e., Figure 11 The second axis 2213 in the structure rotates, and the second axis 2213 is a virtual axis. The end of the support part 23 can be set at the virtual axis. In this way, when the rotating part 222 drives the support part 23 to rotate, the distance between the end of the support part 23 and the end of the connecting part 21 changes little, which can reduce the gap between the support part 23 and the connecting part 21 in each state and improve the appearance of the bracket structure 2.

[0158] In some embodiments, a limiting structure (such as a stepped surface) may be provided in the first arc-shaped groove 2211. The limiting structure can limit the sliding range of the first slider 2221 to reduce the risk of the first slider 2221 disengaging from the first arc-shaped groove 2211.

[0159] In some embodiments, the base 221 may also be provided with a second arc-shaped groove 2212, the second arc-shaped groove 2212 coincides with the central axis of the first arc-shaped groove 2211, and the rotating member 222 is provided with a second slider (not shown in the figure) that matches the second arc-shaped groove 2212. The rotating member 222 slides and adapts to the second arc-shaped groove 2212 through the second slider.

[0160] By setting a second arc groove 2212 that coincides with the central axis of the first arc groove 2211, the stability of the rotation of the rotating component 222 can be increased, thereby improving the stability of the support structure 2 during the unfolding and closing process.

[0161] Reference Figure 7 and Figure 8 In some embodiments, the pivot assembly 22 further includes a first elastic element 224, which is connected to both the base 221 and the rotating element 222. The first elastic element 224 drives the rotating element 222 to rotate, thereby driving the support portion 23 to unfold. By connecting the first elastic element 224 to both the base 221 and the rotating element 222, the first elastic element 224 can drive the rotating element 222 to rotate relative to the base 221, providing the power for the unfolding of the support structure 2. Furthermore, when the support portion 23 supports the display screen 100, the elastic force of the first elastic element 224 can also keep the rotating element 222 and the support portion 23 unfolded, ensuring the stability of the electronic device.

[0162] In some embodiments, under the elastic force of the first elastic member 224, the included angle formed between the support portion 23 and the second surface of the housing 1 can be in the range of 5° to 60°, so that the display screen 100 can be tilted at a specific angle, making it convenient for users to view the images displayed on the display screen 100.

[0163] In some embodiments, the first elastic element 224 is a torsion spring, which is movably mounted on the base 221. The rotating shaft assembly 22 also includes a mounting member 223 and a first connecting shaft 2231 disposed at one end of the mounting member 223. The first connecting shaft 2231 is connected to the rotating member 222. The end of the mounting member 223 facing away from the first connecting shaft 2231 is slidably connected to the base 221. The torsion spring is sleeved on the first connecting shaft 2231. One end of the torsion spring abuts against the rotating member 222, and the other end of the torsion spring abuts against the base 221 through the mounting member 223. When the torsion spring drives the rotating member 222 to rotate relative to the base 221, the rotating member 222 can pull the mounting member 223 to move through the first connecting shaft 2231 so that the torsion spring can always abut against the rotating member 222 and the mounting member 223.

[0164] When the rotating component 222 rotates relative to the base 221 under the elastic force of the torsion spring, the rotating component 222 can pull the mounting component 223 to rotate, so that the torsion spring can always resist the rotating component 222 and the mounting component 223. In this way, the amount of change in the elastic force of the torsion spring acting on the rotating component 222 can be reduced, so that when the support part 23 supports the display screen 100, the rotating component 222 can remain unfolded under the elastic force of the torsion spring.

[0165] Continue to refer to Figure 7 and Figure 8 In some embodiments, a second connecting shaft 2232 is provided at the end of the mounting member 223 opposite to the first connecting shaft 2231, and the base 221 is provided with a sliding groove 2214 that matches the second connecting shaft 2232. The mounting member 223 is slidably adapted to the sliding groove 2214 via the second connecting shaft 2232. When the position of the mounting member 223 changes due to the drive of the rotating member 222, the second connecting shaft 2232 can slide within the sliding groove 2214 to adapt to the position change of the mounting member 223, thereby ensuring that the mounting member 223 always abuts against the torsion spring.

[0166] In other embodiments, the pivot assembly 22 may not include the mounting member 223, the base 221, and the rotating member 222. In this case, the pivot assembly may only include the pivot and the torsion spring sleeved on the pivot. The support part 23 and the connecting part 21 can be rotatably connected by the pivot. The torsion spring sleeved on the pivot can abut against the support part 23 and the connecting part 21 respectively.

[0167] In some embodiments, the housing assembly 300 further includes a first elastic member 224, one end of which contacts the housing 1, and the other end of which is connected to the support portion 23 of the support structure. The first elastic member 224 is used to drive the support portion 23 to rotate relative to the housing 1, so that the support structure 2 is in an unfolded state; see reference. Figure 4 The housing assembly 300 also includes a locking structure 3, see reference. Figure 4 In (a), the locking structure 3 is used to provide a first force to the support structure 2 so that the support structure 2 is in a closed state, and the first force is used to overcome the elastic force of the first elastic element 224; see reference. Figure 4 (b) and Figure 4 In (c), the locking structure 3 is also used to cancel or reduce the first force so that the support structure 2 is in an unfolded state under the elastic force of the first elastic member 224.

[0168] It should be noted that the first force can be greater than the elastic force of the first elastic member 224, and the direction of the first force can be opposite to the direction of the elastic force of the first elastic member 224, so that the first force can overcome the elastic force of the first elastic member 224 and keep the support structure 2 in a closed state.

[0169] The first elastic element 224 and the locking structure 3 are provided. When the first force of the locking structure 3 disappears, the locking structure 3 is in the unlocked state. At this time, the bracket structure 2 can automatically unfold under the elastic action of the first elastic element 224. When the locking structure 3 is in the locked state, the first force provided by the locking structure 3 can keep the bracket structure 2 in the closed state. At this time, the electronic device can be easily stored, thus facilitating the use of the electronic device.

[0170] In some embodiments, when it is necessary to change the support structure 2 from the unfolded state to the closed state, an external force can be used to rotate the support part 23 of the support structure 2 to fit against the housing 1, and restore the first force of the locking structure 3 so that the locking structure 3 can resist the elastic force of the first elastic member 224 to lock the support structure 2. At this time, the support structure 2 will not unfold under the elastic force of the first elastic member 224, and the support structure 2 can remain in the closed state.

[0171] Continue to refer to Figure 4 The locking structure 3 includes a third magnetic element 31 disposed in the support portion 23 and a fourth magnetic element 32 disposed in the housing 1; the third magnetic element 31 and the fourth magnetic element 32 can magnetically attract each other to provide a first force so that the support structure 2 remains closed; the first force can decrease or disappear as the attraction force between the third magnetic element 31 and the fourth magnetic element 32 decreases.

[0172] It should be noted that when the adsorption force between the third magnetic element 31 and the fourth magnetic element 32 decreases to the point that the first force is less than the elastic force of the first elastic element 224, the first elastic element 224 can drive the support part 23 to rotate relative to the housing 1 so that the bracket structure 2 is in the unfolded state.

[0173] A third magnetic element 31 is provided inside the support part 23, and a fourth magnetic element 32 is provided inside the housing 1. When the third magnetic element 31 and the fourth magnetic element 32 are magnetically attracted, they can provide a first force. At this time, the support part 23 can be attracted to the housing 1 so that the bracket structure 2 is in a closed state. When the magnetic attraction force of the third magnetic element 31 and the fourth magnetic element 32 decreases, the elastic force of the first elastic element 224 can overcome the force between the third magnetic element 31 and the fourth magnetic element 32 so as to unfold the bracket structure 2.

[0174] In some embodiments, when it is necessary to switch the support structure 2 from the unfolded state to the closed state, the support part 23 can be manually rotated so that the support part 23 fits against the housing 1, and the first force provided by the third magnetic element 31 and the fourth magnetic element 32 of the locking structure 3 is restored. The locking structure 3 can overcome the elastic force of the first elastic element 224 so that the support structure 2 can remain in the closed state.

[0175] Continue to refer to Figure 4 In some embodiments, at least one of the third magnetic element 31 and the fourth magnetic element 32 can move along a direction perpendicular to the thickness of the housing 1, such that the positions of the third magnetic element 31 and the fourth magnetic element 32 are opposite or staggered; see reference Figure 4 In (a), when positioned relative to each other, the third magnetic element 31 and the fourth magnetic element 32 are used for magnetic attraction to provide a first force; see reference. Figure 4 In (b), when the positions are misaligned, the first force decreases or disappears, so that the support structure 2 can be as follows: Figure 4 Expanded as shown in (c) in the diagram.

[0176] Figure 12 This is a schematic diagram of the driving structure 4 and magnetic components provided in an embodiment of this application. It should be noted that at least one of the third magnetic component 31 and the fourth magnetic component 32 can move along a direction perpendicular to the thickness of the housing 1. Specifically, the third magnetic component 31 can move along a direction perpendicular to the thickness of the housing 1, or the fourth magnetic component 32 can move along a direction perpendicular to the thickness of the housing 1, or both the third magnetic component 31 and the fourth magnetic component 32 can move along directions perpendicular to the thickness of the housing 1. Regardless of which magnetic component moves, a relative displacement will occur between the third magnetic component 31 and the fourth magnetic component 32, causing a change in their positions and thus altering the magnitude of the first force generated between them. Furthermore, regarding movement along a direction perpendicular to the thickness of the housing 1, refer to... Figure 4 It can move linearly in a plane perpendicular to the thickness direction of shell 1, as shown in the reference. Figure 12 It can also swing in a plane perpendicular to the thickness direction of the shell 1.

[0177] By driving at least one of the third magnetic element 31 and the fourth magnetic element 32 to move to change the relative position of the third magnetic element 31 and the fourth magnetic element 32, the magnetic attraction force between the third magnetic element 31 and the fourth magnetic element 32 can be weakened to reduce the first force. This can unlock the locking structure 3 so that the support structure 2 can be deployed under the elastic force of the first elastic element 224.

[0178] In some embodiments, the third magnetic element 31 includes a first magnetic pole 311 and a second magnetic pole 312, and the fourth magnetic element 32 includes a third magnetic pole 321 and a fourth magnetic pole 322. The first magnetic pole 311 is magnetically attracted to the third magnetic pole 321, and the second magnetic pole 312 is magnetically attracted to the fourth magnetic pole 322 to provide a first force. (Refer to...) Figure 4 In (b), when the third magnetic element 31 and the fourth magnetic element 32 are misaligned, the first magnetic pole 311 can be positioned opposite the fourth magnetic pole 322 to generate magnetic repulsion, and the second magnetic pole 312 can be positioned opposite the third magnetic pole 321 to generate magnetic repulsion. At this time, the first force provided by the third magnetic element 31 and the fourth magnetic element 32 disappears, and the magnetic repulsion generated between the third magnetic element 31 and the fourth magnetic element 32 can provide a second force. The second force can drive the support part 23 to rotate relative to the shell 1. At this time, the support structure 2 can be deployed under the combined action of the second force and the elastic force of the first elastic element 224. It should be noted that during the deployment of the support structure 2, the distance between the third magnetic element 31 and the fourth magnetic element 32 gradually increases, and the second force provided by the third magnetic element 31 and the fourth magnetic element 32 due to magnetic repulsion gradually decreases.

[0179] In some embodiments, multiple third magnetic elements 31 may be provided, and these multiple third magnetic elements 31 may be arranged in an array. For example, when two third magnetic elements 31 are provided, the first magnetic pole 311 of one of the third magnetic elements 31 may be opposite to the first magnetic pole 311 of the other third magnetic element 31, so that no repulsive force is generated between the two third magnetic elements 31. The same principle applies when three or more third magnetic elements 31 are provided, and the embodiments of this application will not be described in detail here. In addition, multiple fourth magnetic elements 32 may be provided, and these multiple fourth magnetic elements 32 may be arranged in an array. Thus, without changing the dimensions of the third magnetic component 31 and the fourth magnetic component 32, the magnetic force between the housing 1 and the support 23 can be increased. Conversely, while keeping the magnetic force between the housing 1 and the support 23 unchanged, the dimensions of the third magnetic component 31 and the fourth magnetic component 32 can be appropriately reduced, thereby reducing the travel distance required for the third magnetic component 31 and the fourth magnetic component 32 to be misaligned, which also reduces the reserved space required for the misalignment of the third magnetic component 31 and the fourth magnetic component 32, thus helping to improve the compactness of the structure.

[0180] Continue to refer to Figure 4 In some embodiments, a driving structure 4 is provided inside the housing 1. The driving structure 4 is connected to the third magnetic element 31 and / or the fourth magnetic element 32, and is used to drive the third magnetic element 31 and / or the fourth magnetic element 32 to move. For example, Figure 4 The driving structure 4 shown is connected to the fourth magnetic element 32 disposed in the housing 1, and the driving structure 4 can drive the fourth magnetic element 32 to move.

[0181] A drive structure 4 is provided inside the housing 1, which can drive the fourth magnetic component 32 to move. This reduces the difficulty of adjusting the position of the fourth magnetic component 32, thus making it easier to unfold the support structure.

[0182] Reference Figure 4 and Figure 12 In some embodiments, the drive structure 4 includes a shape memory alloy (SMA) component 41, which is used to be heated and contracted upon being energized to drive the movement of the third magnetic element 31 and / or the fourth magnetic element 32.

[0183] SMA assembly 41 may include an SMA driver 411 and an SMA element 412. The SMA driver 411 may be connected to the control mechanism of an electronic device (not shown), and the SMA element 412 may be connected to the fourth magnetic element 32. The SMA element 412 is an alloy material that, after being plastically deformed and fixed under certain conditions, can recover its initial shape before deformation when external conditions (such as temperature, stress, etc.) change. For example, see reference... Figure 4In (a), at room temperature (e.g., 25°C), SMA part 412 can be in the first state; see reference. Figure 4 In (b), when the SMA driver 411 applies current to the SMA component 412, raising the temperature of the SMA component 412 to a certain level (e.g., to 85°C~95°C), the SMA component 412 will deform into the second form; see reference. Figure 4 In (c), when the SMA driver 411 is powered down, causing the temperature of the SMA component 412 to return to room temperature (e.g., 25°C), the SMA component 412 can return to its first state. Common SMA components 412 include nickel-titanium shape memory alloys, copper-based shape memory alloys, iron-based shape memory alloys, etc. In some embodiments, the temperature of the SMA component 412 after the SMA driver 411 applies current to it and heats it up may not exceed 120°C.

[0184] Because the SMA component 41 has shape recovery characteristics, it can undergo plastic deformation under certain conditions, and automatically return to its initial shape when external conditions (such as temperature, stress, etc.) change. This characteristic enables it to achieve reciprocating driving action. That is, when the conditions (such as temperature, etc.) change, the SMA component 41 can deform to drive the fourth magnetic component 32 to move, so that the fourth magnetic component 32 and the third magnetic component 31 are misaligned. At this time, the locking structure 3 cancels the first force to unlock. When the conditions return to normal, the SMA component 41 can drive the fourth magnetic component 32 to reset during the shape recovery process. At this time, when the support part 23 is rotated to fit against the second surface of the housing 1, the locking structure 3 can restore the first force and keep the bracket structure 2 in a closed state.

[0185] It is understandable that the deformation shape of the SMA component 412 can affect the direction of movement of the fourth magnetic component 32. For example, refer to Figure 4 The SMA component 412 can drive the fourth magnetic component 32 to move linearly, see reference. Figure 12 (a) and Figure 12 In (b), the deformation generated by the SMA component 412 can drive the fourth magnetic component 32 to swing, and the swing direction of the fourth magnetic component 32 is parallel to the plane perpendicular to the thickness direction of the housing 1.

[0186] In some embodiments, after the SMA driver 411 is powered on and causes the SMA component 412 to deform, the SMA driver 411 can automatically power off after a preset time (such as 2 seconds, 3 seconds, etc.). In other embodiments, a sensor connected to the SMA driver 411 can be provided in the housing 1, and the SMA driver 411 can be triggered by the sensor to power off the SMA driver 411.

[0187] In some embodiments, an insulating layer may be provided on the surface of the SMA component 412. In this way, when the SMA component 412 comes into contact with other components in the electronic device, the insulating layer can insulate the SMA component 412 from the corresponding components, thereby reducing the risk of short circuits in the electronic device and improving the stability of the electronic device.

[0188] Figure 13 This is a schematic diagram of the structure of an electronic device provided in another embodiment of this application. (Refer to...) Figure 13 In some embodiments, the drive structure 4 includes a motor 42, the output shaft 422 of which is connected to a corresponding magnetic element to drive the third magnetic element 31 and / or the fourth magnetic element 32 to move. For example, the output shaft 422 of the motor 42 may be connected to the fourth magnetic element 32 to drive the fourth magnetic element 32 to move relative to the third magnetic element 31.

[0189] In some embodiments, the motor 42 can be a linear motor. In this case, the output shaft 422 of the motor 42 can move linearly relative to the body 421 of the motor 42, thereby driving the fourth magnetic element 32 to move linearly. In other embodiments, the output shaft 422 of the motor 42 can rotate. In this case, a gear and rack assembly can be provided to convert the rotational motion of the output shaft 422 into the linear motion of the fourth magnetic element 32.

[0190] By using motor 42 to drive the fourth magnetic component 32, the position of the fourth magnetic component 32 can be easily adjusted, changing the magnetic attraction force between the fourth magnetic component 32 and the third magnetic component 31. This allows the locking structure 3 to generate a first force to keep the support structure 2 in a closed state, or to cancel the first force to unfold the support structure 2. In addition, when the support part 23 is rotated to fit against the housing 1, motor 42 can also drive the fourth magnetic component 32 to reset, so that the locking structure 3 can restore the first force and keep the support structure 2 in a closed state.

[0191] In some embodiments, after the motor 42 drives the fourth magnetic component 32 to move, after a preset time (such as 2 seconds, 3 seconds, etc.), the motor 42 can automatically reverse so that its output shaft 422 can drive the fourth magnetic component 32 to reset. In other embodiments, a sensor connected to the motor 42 can be provided in the housing 1, and the motor 42 can be triggered by the sensor to reverse the output shaft 422 of the motor 42.

[0192] Figure 14 This is a schematic diagram of the driving structure 4 and the magnetic component provided in another embodiment of this application. (Refer to...) Figure 14In some embodiments, the drive structure 4 may also include a carrier 45, and the fourth magnetic element 32 may be installed in the slot of the carrier 45. The SMA component 41 or the motor 42 of the drive structure 4 may be connected to the carrier 45. That is, the SMA component 41 or the motor 42 may be connected to the fourth magnetic element 32 through the carrier 45 to drive the fourth magnetic element 32 to move. This facilitates installation.

[0193] In some embodiments, the driving structure 4 further includes a second elastic element 43, one end of which is connected to the housing 1, and the other end of which is connected to the third magnetic element 31 and / or the fourth magnetic element 32, so that when the force that drives the third magnetic element 31 and the fourth magnetic element 32 to be misaligned disappears, the second elastic element 43 can drive the third magnetic element 31 and / or the fourth magnetic element 32 to reset.

[0194] When the driving structure 4 is connected to the third magnetic element 31 to drive the third magnetic element 31 to move, the end of the second elastic element 43 facing away from the housing 1 can be connected to the third magnetic element 31 to drive the third magnetic element 31 to reset. When the driving structure 4 is connected to the fourth magnetic element 32 to drive the fourth magnetic element 32 to move, the end of the second elastic element 43 facing away from the housing 1 can be connected to the fourth magnetic element 32 to drive the fourth magnetic element 32 to reset. Furthermore, the elastic force of the second elastic element 43 can be less than the force of the driving structure 4, so that the driving structure 4 can overcome the elastic force of the second elastic element 43 to drive the corresponding magnetic element to move.

[0195] The second elastic element 43 is connected to the housing 1 and the third magnetic element 31 and / or the fourth magnetic element 32 respectively. When the force applied by the driving structure 4 to the third magnetic element 31 and / or the fourth magnetic element 32 disappears, the elastic force of the second elastic element 43 can drive the third magnetic element 31 and / or the fourth magnetic element 32 to reset, so that the locking structure 3 can provide the first force again and realize the reuse of the locking structure 3.

[0196] In this embodiment, the driving structure 4 is connected to the fourth magnetic element 32 to drive the fourth magnetic element 32 to move, and the second elastic element 43 can be connected to the housing 1 and the fourth magnetic element 32 respectively.

[0197] In some embodiments, the second elastic element 43 may be a spring.

[0198] Reference Figure 4 and Figure 13In some embodiments, the housing 1 may be provided with a first limiting member 14, and the end of the second elastic member 43 facing away from the fourth magnetic member 32 may be provided with a second limiting member 44. The second limiting member 44 abuts against the first limiting member 14. When the SMA assembly 41 or the motor 42 drives the fourth magnetic member 32 to move to be misaligned with the position of the third magnetic member 31, the second elastic member 43 is compressed. When the SMA driver 411 of the SMA assembly 41 is powered off or the output shaft 422 of the motor 42 moves in the opposite direction, the fourth magnetic member 32 can be reset under the combined action of the second elastic member 43 and the SMA assembly 41 or the motor 42.

[0199] Figure 15 This is a schematic diagram of the structure of an electronic device provided in another embodiment of this application. (Refer to...) Figure 15 In some embodiments, at least one of the third magnetic element 31 and the fourth magnetic element 32 can rotate along the axis of the magnetic element so that the different magnetic pole positions of the third magnetic element 31 and the fourth magnetic element 32 are opposite or misaligned; when the different magnetic pole positions are opposite, they are used for magnetic attraction to provide a first force; when the different magnetic pole positions are misaligned, the first force is reduced or disappears.

[0200] It should be noted that at least one of the third magnetic element 31 and the fourth magnetic element 32 can rotate along the axis of the magnetic element. This can be either the third magnetic element 31 rotating along its own axis, or the fourth magnetic element 32 rotating along its own axis, or both the third magnetic element 31 and the fourth magnetic element 32 rotating along their own axes. However, regardless of which magnetic element rotates, the relative position of the third magnetic element 31 and the fourth magnetic element 32 will change, thereby altering the magnitude of the first force generated between them.

[0201] At least one of the third magnetic element 31 and the fourth magnetic element 32 can rotate along the axis of the magnetic element, which can reduce the space occupied by the corresponding magnetic element when adjusting its position, thus helping to improve the compactness of the structure and reduce the overall size of the electronic device.

[0202] In this embodiment, the fourth magnetic element 32 can rotate along its own axis.

[0203] In some embodiments, the third magnetic element 31 includes a first magnetic pole 311 and a second magnetic pole 312, and the fourth magnetic element 32 includes a third magnetic pole 321 and a fourth magnetic pole 322, as shown in the figure. Figure 15 In (a), the first magnetic pole 311 can magnetically attract the third magnetic pole 321, and the second magnetic pole 312 can magnetically attract the fourth magnetic pole 322 to provide the first force, as shown in reference. Figure 15In (b), when the fourth magnetic element 32 rotates 180° along its own axis, the first magnetic pole 311 can be positioned opposite the fourth magnetic pole 322 to generate a magnetic repulsion force, and the second magnetic pole 312 can be positioned opposite the third magnetic pole 321 to generate a magnetic repulsion force. At this time, the first force provided by the third magnetic element 31 and the fourth magnetic element 32 disappears, and the magnetic repulsion force generated between the third magnetic element 31 and the fourth magnetic element 32 can provide a second force, as shown in reference. Figure 15 In (c), the second force can drive the support part 23 to rotate relative to the shell 1. At this time, the bracket structure 2 can be deployed under the combined action of the second force and the elastic force of the first elastic member 224.

[0204] Figure 16 This is a schematic diagram of the structure of the SMA component 412 provided in an embodiment of this application. In some embodiments, the driving structure 4 includes an SMA assembly 41, which may include an SMA driver 411 and an SMA component 412. The SMA driver 411 may be connected to the control mechanism of an electronic device, and the SMA component 412 may be connected to the fourth magnetic component 32. (Refer to...) Figure 16 In (a), at room temperature (e.g., 25°C), SMA part 412 can be in the first state; see reference. Figure 16 In (b), when the SMA driver 411 applies current to the SMA component 412, raising the temperature of the SMA component 412 to a certain level, the SMA component 412 can twist and deform to drive the fourth magnetic component 32 to rotate; see reference. Figure 16 In (b), when the SMA driver 411 is powered down and the temperature of the SMA component 412 returns to normal (e.g., 25°C), the SMA component 412 can return to the first state.

[0205] In other embodiments, the drive structure 4 includes a motor 42, the output shaft 422 of which can rotate. For example, the output shaft 422 of the motor 42 can rotate 180° to drive the fourth magnetic element 32 to rotate 180°. Of course, a speed reduction structure can also be provided between the output shaft 422 and the fourth magnetic element 32 so that the fourth magnetic element 32 rotates 180° when the output shaft 422 of the motor 42 rotates several times. In other embodiments, the motor 42 can also be a linear motor. In this case, a gear and rack assembly can be provided to convert the linear motion of the output shaft 422 of the motor 42 into the rotational motion of the fourth magnetic element 32.

[0206] In other embodiments, at least one of the third magnetic element 31 and the fourth magnetic element 32 is an electromagnet, and the direction of the magnetic poles of the electromagnet can be changed or the magnetic field of the electromagnet can be reduced, so as to reduce the attraction force between the third magnetic element 31 and the fourth magnetic element 32.

[0207] It should be noted that the third magnetic component 31 can be set as an electromagnet, in which case the fourth magnetic component 32 can be set as a permanent magnet; or the fourth magnetic component 32 can be set as an electromagnet, in which case the third magnetic component 31 can be set as a permanent magnet; or both the third magnetic component 31 and the fourth magnetic component 32 can be set as electromagnets.

[0208] At least one of the third magnetic element 31 and the fourth magnetic element 32 is an electromagnet. By changing the direction of the magnetic poles of the electromagnet or changing the strength of the magnetic field of the electromagnet, the attraction force between the third magnetic element 31 and the fourth magnetic element 32 can be reduced. In this way, it is not necessary to move or rotate the third magnetic element 31 and the fourth magnetic element 32. The space reserved for the position change of the third magnetic element 31 and the fourth magnetic element 32 can be reduced, thereby improving the compactness of the electronic device structure and helping to reduce the overall size of the electronic device.

[0209] In some embodiments, the electromagnet can be connected to the control mechanism of an electronic device, which can control the direction of the electromagnet's magnetic poles or change the strength of the electromagnet's magnetic field.

[0210] In some embodiments, the attraction between the third magnetic element 31 and the fourth magnetic element 32 can be reduced simply by weakening the magnetic field of the electromagnet, thereby canceling the first force of the locking structure 3. In other embodiments, the direction of the magnetic poles of the electromagnet can be changed so that the third magnetic element 31 and the fourth magnetic element 32 can change from magnetic attraction to magnetic repulsion. In this case, the magnetic repulsion between the third magnetic element 31 and the fourth magnetic element 32 can provide a second force to assist in the deployment of the support structure 2.

[0211] Figure 17 This is a schematic diagram of the structure of an electronic device provided in another embodiment of this application. (Refer to...) Figure 17 In some embodiments, the locking structure 3 includes a first fastening member 33 and a second fastening member 34. The first fastening member 33 is disposed on the housing 1; the second fastening member 34 is disposed on the support portion 23. The first fastening member 33 and the second fastening member 34 can fasten to provide a first force. The first fastening member 33 and the second fastening member 34 can also move relative to each other to separate from each other, so as to cancel the provision of the first force to the support structure 2.

[0212] It should be noted that one of the first fastening component 33 and the second fastening component 34 can be a snap fastener, and the other of the first fastening component 33 and the second fastening component 34 can be a fastening position. Figure 17 The first fastening component 33 shown is the fastening position, and the second fastening component 34 is the snap fastener.

[0213] By setting the first fastening member 33 and the second fastening member 34, the bracket structure 2 can be kept in a closed state when the first fastening member 33 and the second fastening member 34 are fastened together.

[0214] The electronic device provided in this application also includes a control mechanism connected to the locking structure 3 of the housing assembly 300 to control the locking structure 3 of the housing assembly 300 to unlock or lock. When the locking structure 3 is locked, the locking structure 3 is used to provide a first force to the support structure 2 of the housing assembly 300. When the locking structure 3 is unlocked, the locking structure 3 cancels the provision of the first force to the support structure 2.

[0215] A control mechanism is installed inside the electronic device, which can automatically control the locking structure 3 of the housing assembly 300 to unlock or lock, thus facilitating the use of the bracket structure 2.

[0216] For example, the control mechanism can control the locking structure 3 to unlock or lock through the drive structure 4. For instance, the control mechanism can be connected to the SMA driver 411 or motor 42 of the drive structure 4 to control the position of the fourth magnetic element 32. For another example, when the fourth magnetic element 32 is an electromagnet, the control mechanism can control the strength of the magnetic field and the direction of the magnetic poles of the fourth magnetic element 32 by controlling the magnitude and direction of the current supplied to the fourth magnetic element 32.

[0217] In some embodiments, the electronic device further includes a first sensor (not shown) connected to a control mechanism. The first sensor is used to send a first control signal to the control mechanism when it detects that the keyboard 200 of the electronic device has been disassembled. The first control signal is used to trigger the control mechanism to unlock the locking structure 3.

[0218] For example, the first sensor can be installed in the second region 102 of the housing 1, that is, the first sensor can coincide with the projection of the keyboard 200 in the housing 1 when it is stored in the housing 1.

[0219] By setting a first sensor, when the keyboard 200 is removed from the housing 1, the electronic device can automatically control the bracket structure 2 to unfold, thus making it convenient for the user to use.

[0220] The first sensor can be a photoelectric sensor. When the keyboard 200 is housed in the second area 102 of the housing 1, the first sensor can be blocked by the keyboard 200. At this time, the first sensor cannot receive light signals and will not send the first control signal to the control mechanism. When the keyboard 200 is removed from the housing 1, the first sensor is not blocked by the keyboard 200. At this time, the first sensor can receive light signals and be triggered to send the first control signal to the control mechanism, so that the electronic device can automatically control the bracket structure 2 to unfold when the keyboard 200 is removed. In other embodiments, the first sensor can be a Hall sensor. A Hall sensing element can be set at the position of the keyboard 200 corresponding to the Hall sensor. When the keyboard 200 is housed in the second area 102 of the housing 1, the Hall sensor can sense the Hall sensing element but is not triggered. When the keyboard 200 is removed from the housing 1, the Hall sensor cannot detect the Hall sensing element and is triggered, thereby sending the first control signal to the control mechanism. In other embodiments, the first sensor can also be an integrated circuit (IC) sensor. In this case, the keyboard 200 can be equipped with an IC chip. In addition, the first sensor can also be a sensor of the type of infrared sensor, etc.

[0221] In some embodiments, the electronic device also includes a second sensor (not shown) disposed within the housing 1. The second sensor is used to detect a user's trigger operation on a target area on the display screen 100 and to send a trigger operation to a control mechanism. The control mechanism is used to control the locking structure 3 to unlock if the trigger operation matches a preset trigger operation.

[0222] By using a second sensor to detect the user's trigger operation information, the electronic device can unfold the support structure 2 according to the user's instructions, thereby facilitating the use of the support structure 2. For example, the user can set a specific touch gesture (such as tapping a target area) to trigger the second sensor, so that after receiving the trigger operation, the second sensor can send a trigger operation to the control mechanism, thereby enabling the control mechanism to control the unlocking of the locking structure 3 when the trigger operation matches the preset trigger operation.

[0223] In some embodiments, the electronic device may be equipped with both a first sensor and a second sensor. That is, the control mechanism may trigger the unlocking and locking structure 3 by the first control signal sent by the first sensor, or it may control the unlocking and locking structure 3 when the triggering operation matches the preset triggering operation. In this way, the electronic device may automatically unfold the support structure 2 when the user removes the keyboard 200, or unfold the support structure 2 by the user's command when the keyboard 200 is not removed.

[0224] In some embodiments, the electronic device is equipped with a button. When the button is pressed, it sends a second control signal to the control mechanism, which triggers the control mechanism to unlock the locking mechanism 3. In this embodiment, the button may be specifically designed to trigger the control mechanism, or it may be a volume button, power button, or other similar button on the electronic device. It is triggered by setting a specific pressing frequency or pressing combination (such as double-clicking the volume button) to send the second control signal to the control mechanism.

[0225] Users can trigger the second sensor by pressing a button, so that the control mechanism can unlock the locking structure 3 after receiving the second control signal sent by the button, thereby unfolding the bracket structure 2, which makes it convenient to use.

[0226] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
