Description

Technical Field

[0001] This application relates to the field of foldable electronic device design technology, and more particularly to a foldable electronic device. Background Technology

[0002] With the continuous development of mobile phones and other electronic devices, foldable phones have gradually appeared in the public eye. Foldable phones are the size of a normal phone when unfolded, and only half the size when folded, thus greatly satisfying users' needs for portability. In addition to the foldable main screen, foldable phones also have a secondary display screen, used to display information in the folded state to meet users' daily needs for checking the time, weather, making and receiving calls, replying to messages, and playing music.

[0003] In existing electronic devices, the size of the first display screen of foldable phones is usually fixed. The size of the first display screen depends on the size of the phone after folding. In order not to affect the normal use of the phone's camera and other functional components, the screen ratio of the first display screen should not be too large, which results in limited content and display effect on the first display screen, making it difficult to meet the increasing usage needs of users. Summary of the Invention

[0004] This application provides a foldable electronic device to solve the problem that the size of the first display screen in existing electronic devices is fixed and the screen ratio is low, which limits the display content and display effect.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a foldable electronic device, including:

[0007] A first housing and a second housing, which are rotatably connected, and a display window is provided on a first side of the first housing;

[0008] A first display screen is disposed on a first side of the first housing to display information through the viewing window;

[0009] The second display screen is located on the second side of the first housing.

[0010] A driving component is used to drive the first display screen to move in order to change the display area of ​​the first display screen in the window.

[0011] Compared to existing technologies, the foldable electronic device of this application has the following advantages:

[0012] The foldable electronic device of this application includes a first housing, a second housing, a first display screen, a second display screen, and a driving component. The first housing and the second housing are rotatably connected. A display window is provided on a first side of the first housing, through which the first display screen displays information. The second display screen is located on a second side of the first housing. The driving component can drive the first display screen to move, thereby changing the display area of ​​the first display screen in the window. The larger the display area of ​​the first display screen in the window, the more content can be displayed and the better the display effect. Thus, when the user needs to use the first display screen, the driving component drives the first display screen to move, thereby increasing the screen-to-body ratio of the first display screen, allowing the first display screen to display more content, improving the display effect of the first display screen, and meeting the user's usage needs.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0023] In the various embodiments of this application, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0024] Reference Figure 1 and Figure 2 This application provides a foldable electronic device, including: a first housing 11 and a second housing 12, which are rotatably connected. A display window 110 is provided on a first side of the first housing 11; a first display screen 21, which is disposed on the first side of the first housing 11 to display through the display window 110; a second display screen 22, which is disposed on the second side of the first housing 11; and a driving component 3, which is used to drive the first display screen 21 to move so as to change the display area of ​​the first display screen 21 in the display window 110.

[0025] In this embodiment, foldable electronic devices include, but are not limited to, mobile phones, tablets, game consoles, and other devices. Figure 2As shown, the electronic device includes a first housing 11 and a second housing 12, which are rotatably connected to enable the electronic device to be foldable. A display window 110 is provided on the first side of the first housing 11, and a first display screen 21 is located on the first side of the first housing 11, displaying content through the window 110. A second display screen 22 is located on the second side of the first housing 11. The first and second sides of the first housing 11 can be opposite sides or adjacent sides, depending on the usage requirements of the electronic device; this embodiment does not impose any limitations on this. The second display screen 22 can serve as the primary screen for daily use, with a larger screen area than the first display screen 21, capable of displaying various media information with a richer variety and more comprehensive content. The first display screen 21 can serve as a secondary screen for daily use, displaying content through the window 110, including frequently viewed media information such as time, weather, music, and contact information, enabling basic user operations. Of course, the first display screen 21 and the second display screen 22 can also be touch-enabled displays, allowing users to perform touch operations on the first display screen 21 or the second display screen 22 to enable the electronic device to perform different functions.

[0026] In some embodiments, a decorative ring 6 may be provided on the outer side of the viewing window 110 on the first housing 11. The decorative ring 6 may be made of hard plastic, metal, or alloy and has certain properties such as resistance to bending deformation and load impact, serving as the housing of the electronic device. The decorative ring 6 is pressed and connected to the edge of the first housing 11. After connection, the first display screen 21 can be pressed into the viewing window 110, thereby preventing the edge of the first display screen 21 from warping. The size of the decorative ring 6 is slightly larger than the size of the first display screen 21. The display content of the first display screen 21 can be displayed through the hollow part of the decorative ring 6, and the display effect is not affected by the decorative ring 6. It should be noted that the decorative ring 6 is fixed to the first housing 11, while the first display screen 21 can move relative to the first housing 11 under the action of the driving component 3. When the first display screen 21 moves to occupy a portion of the area within the viewing window 110, at least one edge of the first display screen 21 is in a free state and does not contact the decorative ring 6.

[0027] The driving component 3 can drive the first display screen 21 to move, thereby changing the display area of ​​the first display screen 21 in the window 110. Under the drive of the driving component 3, the first display screen 21 can perform translational movement or roll-up movement; the specific movement form is not limited in this embodiment. It can be understood that the larger the display area of ​​the first display screen 21 in the window 110, the more content can be displayed and the better the display effect; the smaller the display area of ​​the first display screen 21 in the window 110, the less content can be displayed and the worse the display effect. Therefore, by driving the first display screen 21 to move through the driving component 3, the problem of the display screen and device housing being relatively fixed in the prior art can be solved. When the user needs to use the first display screen 21, the driving component 3 drives the display area of ​​the first display screen 21 in the window 110 to increase the screen ratio, enabling the first display screen 21 to display more content, improving the display effect of the first display screen 21, and meeting the user's needs.

[0028] The foldable electronic device of this application includes a first housing 11, a second housing 12, a first display screen 21, a second display screen 22, and a driving component 3. The first housing 11 and the second housing 12 are rotatably connected. A display window 110 is provided on the first side of the first housing 11, through which the first display screen 21 displays information. The second display screen 22 is located on the second side of the first housing 11. The driving component 3 can drive the first display screen 21 to move, thereby changing the display area of ​​the first display screen 21 in the display window 110. The larger the display area of ​​the first display screen 21 in the display window 110, the more content can be displayed and the better the display effect. Thus, when the user needs to use the first display screen 21, the driving component 3 drives the first display screen 21 to move, thereby increasing the screen ratio of the first display screen 21, allowing the first display screen 21 to display more content, improving the display effect of the first display screen 21, and meeting the user's needs.

[0029] Optionally, refer to Figure 3 and Figure 4 The foldable electronic device also includes: a functional component 4, which is disposed in the first housing 11 and opposite to the window 110; a driving component 3 drives the first display screen 21 to move, so that the electronic device switches between a first working state and a second working state; when the electronic device is in the first working state, the first display screen 21 and the functional component 4 appear together within the window 110; when the electronic device is in the second working state, the display area of ​​the first display screen 21 in the window 110 increases and blocks the functional component 4.

[0030] In this embodiment, the functional component 4 is located inside the first housing 11 and opposite the viewing window 110. The driving component 3 drives the first display screen 21 to move, causing the electronic device to switch between a first working state and a second working state. The first and second working states of the electronic device are two different states, which can correspond to the unfolded and folded postures of the electronic device. Alternatively, the user can customize the working state of the electronic device, such as the first working state being the unlocked state and the second working state being the locked standby state; or the first working state being the state where the electronic device is editing information or making a phone call, and the second working state being the state where the electronic device is playing a video or game; or the first working state being the state where the electronic device is charging, and the second working state being the state where the electronic device is not charging, etc. Figure 4 As shown, when the electronic device is in its first operating state, the first display screen 21 and the functional component 4 appear together within the viewing window 110, as... Figure 3 As shown, when the electronic device is in the second working state, the display area of ​​the first display screen 21 in the window 110 increases and obscures the functional component 4.

[0031] For example, if functional component 4 is a button component, and the first working state is the state of the electronic device editing information or making a phone call, and the second working state is the state of the electronic device playing a video or playing a game, then when the electronic device is in the state of editing information or making a phone call, the first display screen 21 and the button component appear together within the window 110, so that information can be edited or phone numbers can be entered through the button component. When the electronic device is in the state of playing a video or playing a game, the display area of ​​the first display screen 21 in the window 110 increases and covers the button component, thereby increasing the display area of ​​the first display screen 21. When the user is playing a video, it can improve the user's visual experience, and when the user is playing a game, it can prevent the phenomenon of the user accidentally touching the button component and causing the game to exit. If the function button is a charging port, the first working state is when the electronic device is charging, and the second working state is when the electronic device is not charging. When the electronic device is charging, the first display screen 21 and the charging port appear together within the window 110. The user can insert the charging cable into the charging port to charge the electronic device. When the electronic device is not charging, the display area of ​​the first display screen 21 in the window 110 increases and blocks the charging port. At this time, the display area of ​​the first display screen 21 is larger, which can not only improve the user experience, but also prevent water and dust from entering the charging port, thus providing safety for the electronic device.

[0032] Optionally, refer to Figure 2The foldable electronic device also includes: a detection component 5, which is used to detect the posture of the electronic device, including a folded posture and an unfolded posture; and a driving component 3, which drives the first display screen 21 to move according to the posture of the electronic device to change the display area of ​​the first display screen 21 in the window 110.

[0033] In this embodiment, the detection component 5 is used to detect the posture of the electronic device. The posture of the electronic device includes a folded posture and an unfolded posture. When the first housing 11 and the second housing 12 of the electronic device are rotated relative to each other to a stacked state or to a certain angle between them, the electronic device can be considered to be in a folded posture. When the first housing 11 and the second housing 12 of the electronic device are rotated relative to each other to be on the same plane, the electronic device can be considered to be in an unfolded posture. When the electronic device is in a folded posture, its overall size is small, making it easy to carry and store. When the electronic device is in an unfolded posture, its overall size is large, making it easier for users to use various functions. The driving component 3 can drive the first display screen 21 to move according to the posture of the electronic device, thereby changing the display area of ​​the first display screen 21 in the window 110.

[0034] For example, when the detection component 5 detects that the electronic device is in a folded posture, the detection component 5 sends a first signal to the driving component 3. The driving component 3 then drives the first display screen 21 to move, thereby increasing the display area of ​​the first display screen 21 in the window 110, so that the user can still display content through the first display screen 21 even when the electronic device is in a folded posture. When the detection component 5 detects that the electronic device is in an unfolded posture, the detection component 5 sends a second signal to the driving component 3. The driving component 3 then drives the first display screen 21 to move, thereby decreasing the display area of ​​the first display screen 21 in the window 110. At this time, the user can display content through the second display screen 22. The first signal and the second signal can be any type of electrical signal representing different instructions.

[0035] In some embodiments, the detection component 5 may employ a Hall effect detection device, including a magnetic element 51 and a Hall sensor 52. The magnetic element 51 and the Hall sensor 52 have simple structures and provide accurate detection results, which helps reduce the design difficulty of electronic devices and control the manufacturing cost of electronic devices. The magnetic element 51 is disposed at the end of the first housing 11 away from the second housing 12, and the Hall sensor 52 is disposed at the end of the second housing 12 away from the first housing 11. Alternatively, the magnetic element 51 is disposed at the end of the second housing 12 away from the first housing 11, and the Hall sensor 52 is disposed at the end of the first housing 11 away from the second housing 12. The Hall sensor 52 is electrically connected to the drive component 3. The Hall sensor 52 can detect the usage posture of the electronic device based on the change in the magnetic field between itself and the magnetic element 51. During the folding process of the electronic device, the magnetic element 51 is closer to the Hall sensor 52, and the magnetic flux detected by the Hall sensor 52 is greater. During the unfolding process of the electronic device, the magnetic element 51 is further away from the Hall sensor 52, and the magnetic flux detected by the Hall sensor 52 is smaller. When the magnetic flux detected by the Hall sensor 52 is above a preset threshold, the electronic device is determined to be in a folded posture; when the magnetic flux detected by the Hall sensor 52 is below the preset threshold, the electronic device is determined to be in an unfolded posture. The preset threshold is set manually, and the specific parameters are not limited in this embodiment.

[0036] Optionally, the foldable electronic device further includes: a functional component 4, which is disposed in the first housing 11 and opposite to the window 110; when the electronic device is in an unfolded state, the driving component 3 drives the first display screen 21 to move, so that the first display screen 21 and the functional component 4 appear together within the window 110; when the electronic device is in a folded state, the driving component 3 drives the first display screen 21 to move, so that the display area of ​​the first display screen 21 in the window 110 increases and blocks the functional component 4.

[0037] In this embodiment, the functional component 4 is housed within the first housing 11 and faces the viewing window 110. When the electronic device is in an unfolded position, the second display screen 22 serves as the main screen for user use, and the first display screen 21 serves as the first display screen for user use. The driving component 3 drives the first display screen 21 to move, so that the first display screen 21 and the functional component 4 appear together within the viewing window 110. At this time, the electronic device is relatively large, and the user can use both the functional component 4 and the first display screen 21. Of course, the area ratio of the first display screen 21 and the functional component 4 within the viewing window 110 can be the same or different. If the user needs to use the first display screen 21 more, the area appearing within the viewing window 110 after the first display screen 21 is moved can be larger, even partially obscuring the functional component 4. If the user needs to use the first display screen 21 less, the area appearing within the viewing window 110 after the first display screen 21 is moved can be smaller, so that the functional component 4 is fully exposed within the viewing window 110 for user use. When the electronic device is in a folded position, the second display screen 22 is folded between the first housing 11 and the second housing 12 and cannot be used. The user's basic operations need to be performed through the first display screen 21, thereby driving the first display screen 21 to move, increasing the display area of ​​the first display screen 21 in the window 110 and blocking the functional component 4. At this time, the functional component 4 is completely blocked, and the area of ​​the first display screen 21 within the window 110 is maximized, so that more content can be displayed to meet the user's needs.

[0038] Optionally, the first side and the second side of the first housing 11 are two sides of the first housing 11 that are opposite to each other; the second display screen 22 extends from the first housing 11 to the second housing 12; when the electronic device is in a folded posture, the second display screen 22 is sandwiched between the first housing 11 and the second housing 12, and the first display screen 21 displays the image through the window 110 located on the outside of the electronic device.

[0039] In this embodiment, the first side and the second side of the first housing 11 are opposite sides of the first housing 11, that is, opposite sides of the first housing 11. The second display screen 22 extends from the first housing 11 to the second housing 12. When the electronic device is in a folded posture, the second display screen 22 is sandwiched between the second side of the first housing 11 and the second housing 12. At this time, the second display screen 22 cannot be used. The first display screen 21 is located on the first side of the first housing 11. The first display screen 21 can display the screen through the window 110 located on the outside of the electronic device to meet the user's usage needs.

[0040] Optionally, the functional component 4 includes at least one of the following: a speaker component, a receiver component, a camera component, a button component, a touch component, a charging interface, a fingerprint recognition component, a facial recognition component, a physiological health monitoring component, a card slot component, and a fill light component.

[0041] In this embodiment, the speaker assembly amplifies sound for playing music and videos, the receiver assembly receives sound for making phone calls, the camera assembly performs video recording and photography, the button assembly and touch assembly perform information input and volume adjustment, the fingerprint recognition assembly and facial recognition assembly unlock and lock the electronic device, install applications, and make wallet payments, the physiological health monitoring assembly performs motion monitoring, heart rate monitoring, blood glucose monitoring, and sleep monitoring to help users monitor their health, the card slot assembly installs and fixes electronic device accessories, the fill light assembly provides supplementary lighting during photography or illuminates the surrounding environment in dark environments, and the functional component 4 can be any one or more of the above components, set in the window 110 of the first housing 11, and used when the first display screen 21 is not obstructed.

[0042] For example, if functional component 4 is a speaker component, the speaker component will appear within the window 110 when the electronic device is making a phone call or playing audio to ensure normal speaker function. When the electronic device exits the above state, the first display screen 21 can cover the speaker component to increase the display area of ​​the first display screen 21 within the window 110 and improve the display effect. If functional component 4 is a fingerprint recognition component, the fingerprint recognition component will appear within the window 110 when the electronic device is in a locked state, allowing the user to unlock the electronic device through fingerprint recognition. When the electronic device is in an unlocked state, the first display screen 21 can cover the fingerprint recognition component to increase the display area of ​​the first display screen 21 within the window 110 and improve the display effect. Functional component 4 can be a combination of one or more of the above components, and the specific form is not limited in this embodiment.

[0043] Optionally, refer to Figure 1Functional component 4 includes multiple camera components; driving component 3 drives the first display screen 21 to move, enabling the electronic device to switch between a first working state, a second working state, and a third working state; when the electronic device is in the first working state, the first display screen 21 and all camera components appear within the viewing window 110, and the display area of ​​the first display screen 21 in the viewing window 110 is A; when the electronic device is in the second working state, the first display screen 21 blocks all camera components, and the display area of ​​the first display screen 21 in the viewing window 110 is B; when the electronic device is in the third working state, the first display screen 21 and some camera components appear within the viewing window 110, and the display area of ​​the first display screen 21 in the viewing window 110 is C; wherein, A < C < B.

[0044] In this embodiment, when functional component 4 includes multiple camera components, the electronic device may include a first working state, a second working state, and a third working state. In some embodiments, the first working state represents a high-quality shooting mode, the second working state represents a non-shooting mode, and the third working state represents a normal shooting mode. When the electronic device is in high-quality shooting mode, the driving component 3 drives the first display screen 21 to move, so that the first display screen 21 and all camera components appear within the viewport 110, ensuring sufficient cameras for shooting, improving shooting quality, and obtaining high-quality images. At this time, the display area of ​​the first display screen 21 in the viewport 110 is A. When the electronic device is in non-shooting mode, the driving component 3 drives the first display screen 21 to move, so that the first display screen 21 blocks all camera components. At this time, the display area of ​​the first display screen 21 in the viewport 110 is B. When the electronic device is in normal shooting mode, the driving component 3 drives the first display screen 21 to move, so that the first display screen 21 blocks all camera components. Screen 21 and some camera components appear within the viewport 110. The number of cameras is sufficient for normal shooting needs. At this time, the display area of ​​the first display screen 21 in the viewport 110 is C; where A < C < B. That is, the display area of ​​the first display screen 21 in the viewport 110 is smaller in high-definition shooting mode than in normal shooting mode, and smaller in normal shooting mode than in non-shooting mode. This further enhances the flexibility of the first display screen 21 based on the electronic device's operating state. Of course, the three operating states of the electronic device can also be other states, which will not be elaborated upon here.

[0045] Optionally, the first display screen 21 is a rollable flexible display screen; the driving component 3 includes a rotating shaft and a driving member, the rotating shaft is located on one side of the viewing window 110, and the driving member is connected to the rotating shaft; one end of the first display screen 21 is wound around the rotating shaft and fixedly connected to the rotating shaft, and the other end extends freely within the viewing window 110; the driving member drives the rotating shaft to rotate, causing the first display screen 21 to be rolled up and stored on the rotating shaft, so as to change the display area of ​​the first display screen 21 in the viewing window 110.

[0046] In this embodiment, the first display screen 21 is a rollable flexible display screen, which includes a display screen body and a support portion located below the display screen body. The display screen body has good bending and deformation capabilities, and the support portion can support the display screen body, allowing the display screen body to bend and maintain a certain shape. The driving component 3 includes a rotating shaft and a driving element. The rotating shaft is located on one side of the viewing window 110 and is rotatably connected to the first housing 11. The driving element can be a motor 32, which is connected to the rotating shaft and can drive the rotating shaft to rotate relative to the first housing 11. The support portion at one end of the first display screen 21 has a hollow structure. The part of the first display screen 21 with the hollow structure is wound around the rotating shaft and fixedly connected to the rotating shaft. The length of the hollow structure is at least the same as the length of the viewing window to ensure that the first display screen can completely fill the viewing window after being released from the rotating shaft. The other end of the first display screen 21 extends freely within the viewing window 110. During the rotation of the rotating shaft driven by the driving component, the first display screen 21 rotates synchronously with the shaft. As it rotates along the first direction, the first display screen 21 gradually curls up and is stored on the shaft, thus reducing its display area in the viewing window 110. As it rotates along the second direction, the curled-up first display screen 21 gradually releases from the shaft, increasing its display area in the viewing window 110. The first and second directions are opposite directions; if the first direction is clockwise, the second direction is counterclockwise, and vice versa. In this embodiment, the first display screen 21 undergoes multiple curling maneuvers via the shaft, resulting in a high degree of curling. This helps save space occupied by the first display screen 21 within the first housing 11, improving the internal space utilization of the first housing 11, and thus contributing to the miniaturization of the electronic device.

[0047] Optionally, refer to Figure 5 The first display screen 21 is a rollable flexible display screen; the driving component 3 includes a reversing shaft 36 and a driving member. The reversing shaft 36 is located on one side of the viewing window 110 and is rotatably connected to the first housing 11; one end of the first display screen 21 is connected to the driving member, and the other end extends freely within the viewing window 110 around the reversing shaft 36; the driving member drives one end of the first display screen 21 to move, and the other end of the first display screen 21 moves in the opposite direction around the reversing shaft 36, so as to change the display area of ​​the first display screen 21 in the viewing window 110.

[0048] In this embodiment, the flexible display screen includes a display body and a support portion located below the display body. The display body has good bending and deformation capabilities, and the support portion can support the display body, allowing the display body to bend and maintain a certain shape. The driving assembly 3 includes a reversing shaft 36 and a driving component. The reversing shaft 36 is located on one side of the viewing window 110 and is rotatably connected to the first housing 11. The support portion of the first display screen 21 has a hollow structure. The portion of the first display screen 21 with the hollow structure is wound around the reversing shaft 36. The length of the hollow structure is at least the same as the length of the viewing window to ensure that the first display screen can completely fill the viewing window after passing around the reversing shaft 36. The reversing shaft 36 can be a smooth optical shaft to reduce friction between the reversing shaft 36 and the first display screen 21, extending the service life of both the reversing shaft 36 and the first display screen 21. One end of the first display screen 21 is connected to the driving component, and the other end extends freely within the viewing window 110, bypassing the reversing shaft 36. The driving component can drive the first display screen 21 to move. During the movement of the first display screen 21, the end connected to the driving component moves synchronously with the driving component, while the other end moves in the opposite direction, bypassing the reversing shaft 36. Figure 5 As shown, if one end of the first display screen 21 connected to the driving component moves synchronously to the left with the driving component, then the other end of the first display screen 21 moves to the right around the reversing shaft 36. During this process, the display area of ​​the first display screen 21 in the viewing window 110 gradually increases, and the first display screen 21 gradually obscures the functional component 4. If one end of the first display screen 21 connected to the driving component moves synchronously to the right with the driving component, then the other end of the first display screen 21 moves to the left around the reversing shaft 36. During this process, the display area of ​​the first display screen 21 in the viewing window 110 gradually decreases, and the first display screen 21 gradually exposes the functional component 4, thereby realizing the change of the display area of ​​the first display screen 21 in the viewing window 110. In this embodiment, the first display screen 21 only curls once through the reversing shaft 36, and the degree of curling is low, which helps to maintain the flatness of the first display screen 21 in the flat state, thereby ensuring the display effect of the first display screen 21.

[0049] Optionally, refer to Figure 5 and Figure 6 The drive assembly 3 also includes a transmission plate, and the drive component is a motor screw module. The motor screw module is fixedly connected to one end of the first display screen 21 through the transmission plate. The transmission plate includes a first transmission part 311 and a second transmission part 312 that are perpendicular to each other. The first transmission part 311 is fixedly connected to the output end of the motor screw module, and the second transmission part 312 is glued to the first display screen 21.

[0050] In this embodiment, a high-precision motor lead screw module is selected as the driving component. The motor lead screw module includes a motor 32, a lead screw 33, and a nut 34. The nut 34 is rotatably sleeved on the lead screw 33 and threadedly engaged with it. The motor 32 is connected to the lead screw 33 and can drive the lead screw 33 to rotate. During the rotation of the lead screw 33, it will drive the nut 34 to move along the axial direction of the lead screw 33. The nut 34 is fixedly connected to a transmission plate, which is in turn fixedly connected to one end of the first display screen 21. During the movement of the nut 34 along the axial direction of the lead screw 33, the first display screen 21 is driven to move synchronously through the transmission plate, thereby changing the display area of ​​the first display screen 21 in the viewing window 110. Figure 6 As shown, in some embodiments, a guide rod 35 parallel to the lead screw 33 can be provided, and the nut 34 is also inserted in the guide rod 35, which helps to achieve smooth movement of the nut 34, thereby achieving uniform movement of the first display screen 21.

[0051] Furthermore, in this embodiment, the transmission plate can be a rigid plate with an "L"-shaped structure, including a first transmission part 311 and a second transmission part 312 that are perpendicular to each other. The first transmission part 311 is fixedly connected to the output end of the motor lead screw module, i.e., the nut 34, and the second transmission part 312 is adhesively connected to the first display screen 21. The transmission plate and the first display screen 21 are connected by adhesive, which can avoid damage to the first display screen 21 during the connection process, thereby ensuring the display effect of the first display screen 21. In this embodiment, the connection between the first transmission part 311 and the nut 34, and the connection between the second transmission part 312 and the first display screen 21 are all surface contact connections, which can effectively enhance the reliability of the connection between them.
