Description

Technical Field

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

[0002] With the increasing prevalence of international exchanges, cross-border travel, receiving foreign guests, and foreign language communication meetings, electronic devices such as translation machines have become important communication aids due to their ability to quickly break down language barriers, leading to a continuous increase in market demand for their ease of use. However, existing translation devices suffer from significant technical deficiencies in their structural design, making it difficult to meet practical application needs. Most translation devices are equipped with only a single display screen, and the screen size is small, allowing only one person to view the translation content at close range. When it is necessary to show the translation results to the other party, the device must be frequently passed around, which is cumbersome and easily interrupts the communication process, significantly reducing the convenience of use and communication efficiency. Although some devices have added a display screen to solve the problem of single-person viewing, the overall structure of the device has not been optimized, resulting in a bulky device (such as the computer-style translator at the hotel front desk), which is difficult to store and carry, and still has the problem of inconvenience in mobile scenarios, thus limiting the applicability of translation devices and the user experience.

[0031] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0032] In the description of the embodiments of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0034] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples. In the embodiments of this application, "a plurality of" means two or more.

[0036] In addition to the problems described in the background technology, existing electronic devices also have the following defects: small sound pickup range (generally equipped with 2 to 4 microphones around the device, with a short effective sound pickup distance); low speaker volume and short effective listening distance; and screens that are mostly fixed or mechanically spring-loaded, lacking a sense of sportiness and comfortable angle.

[0037] An electronic device according to an embodiment of the first aspect of this application, such as Figures 1 to 3As shown, the electronic device includes a device body 1, a first screen module 2, and a second screen module 3. The first screen module 2 is rotatably mounted on the device body 1 to switch between a stowed state and an operational state. The second screen module 3 is also rotatably mounted on the device body 1 to switch between a stowed state and an operational state. When the first screen module 2 and the second screen module 3 are in the stowed state, the first screen module 2 covers the outside of the second screen module 3 to form the outer surface of the device body 1. When the first screen module 2 and the second screen module 3 are in the operational state, they face a first direction and a second direction, respectively. The electronic device in this application can be a translation device.

[0038] The first and second directions can be opposite directions or adjacent directions. For example... Figure 1 and Figure 2 The middle refers to two opposing directions.

[0039] The electronic device rotatably mounts both the first screen module 2 and the second screen module 3 onto the main body 1. When both are in operation, they face the first direction and the second direction respectively. This allows the two parties to communicate and view translated content through the first screen module 2 and the second screen module 3 respectively, eliminating the need to repeatedly pass the device like traditional single-screen devices. This avoids interruptions in the communication process and effectively improves ease of use and communication efficiency.

[0040] When the first screen module 2 and the second screen module 3 are switched to the storage state, the overall size of the device is significantly reduced. Compared with existing dual-screen devices that are relatively large, it is more convenient for users to carry in mobile scenarios such as cross-border travel and outdoor communication, thus meeting the market's core demand for portable electronic devices.

[0041] Meanwhile, in its stowed state, the first screen module 2 covers the outside of the second screen module 3 and forms the exterior surface of the device body 1. This makes the overall appearance of the device simpler and more unified, improving the product's aesthetics. Furthermore, it eliminates the need for an additional, separate outer shell structure, reducing the number of components, simplifying the overall structure of the electronic device, and lowering material and assembly costs during manufacturing. The rotatable installation method also allows for more flexible switching of the screen module's state, enabling users to quickly adjust it to either working or stowed mode according to the actual communication scenario, further adapting to diverse usage needs.

[0042] According to one embodiment of this application, such as Figure 4 and Figure 5As shown, the electronic device also includes a first rotating mechanism 4; the first rotating mechanism 4 includes a first flip motor 41, a first transmission assembly 42, and a transmission gear component 43, wherein the first flip motor 41 is installed in the device body 1; the first transmission assembly 42 is connected to the output end of the first flip motor 41; the transmission gear component 43 is connected to the first transmission assembly 42 in a transmission connection and is fixedly connected to the first screen module 2. The first flip motor 41 may be a stepper motor with an effective maximum outer diameter of 24mm.

[0043] The first rotating mechanism 4 installs the first flipping motor 41 inside the main body 1 of the equipment, which not only avoids the motor from being exposed to the external environment and being corroded by collisions and dust, thus extending the service life of the first flipping motor 41, but also does not add any external protruding structures to the equipment, which is compatible with the design requirement of reducing the size of the equipment in the storage state and maintaining the simplicity of the overall appearance of the equipment.

[0044] The first flip motor 41 transmits power to the transmission gear component 43 through the first transmission component 42, forming a stable mechanical transmission path. The transmission gear component 43 is fixedly connected to the first screen module 2. The characteristics of gear transmission ensure high power transmission accuracy, which can ensure precise angle control during the rotation of the first screen module 2. When switching to the working state, it can stably maintain a preset position facing the first direction, avoiding the impact on the user's viewing experience due to angle deviation. At the same time, the gear transmission has a strong load-bearing capacity, which can stably support the weight of the first screen module 2 and prevent the position of the first screen module 2 from shifting due to insufficient support of the transmission components after long-term use.

[0045] The first rotating mechanism 4 adopts a modular design of "motor-transmission component-gear component". Each component has an independent function and can be debugged separately during production and assembly, reducing the overall assembly difficulty. If a component fails in the future, only the corresponding faulty component needs to be replaced (such as replacing the first transmission component 42 separately after wear), without disassembling the entire rotating mechanism or the main body of the equipment 1, reducing maintenance costs and complexity, and improving the economic efficiency of equipment use.

[0046] In practical applications, a reduction gearbox can be set in the first transmission component 42 to adjust the speed output of the first flip motor 41, reduce the speed transmitted to the transmission gear component 43, make the rotation process of the first screen module 2 smoother, and avoid the impact when the first screen module 2 switches states due to excessive motor speed.

[0047] In some cases, a buffer assembly can be added to the connection between the first transmission component 42 and the transmission gear component 43. For example, an elastic rubber pad can be embedded between the meshing teeth 431 of the two, or an elastic washer can be placed between the output shaft of the first transmission component 42 and the connection hole of the transmission gear component 43. The buffer assembly can reduce the vibration and noise generated by gear meshing during transmission, improve the quietness of the equipment during use, absorb some of the transmission impact, reduce the wear rate of the first transmission component 42 and the transmission gear component 43, and extend the service life of the entire first rotating mechanism 4.

[0048] The first rotating mechanism 4 may also include a fixed bracket 44, which is used to fix and install the first rotating motor 41, the first transmission component 42 and the transmission gear component 43, etc., and may be a metal structural component.

[0049] According to one embodiment of this application, such as Figure 7 As shown, the transmission gear component 43 is an arc-shaped gear segment, one end of which is fixedly connected to the first screen module 2 along the arc length direction; meshing teeth 431 that cooperate with the first transmission component 42 are provided on the outer circumferential surface of the arc-shaped gear segment; the first screen module 2 and the arc-shaped gear segment rotate together around the center 432 of the arc-shaped gear segment.

[0050] The transmission gear component 43 adopts an arc-shaped gear segment structure. Its characteristic of rotating around its own center can make the rotation trajectory of the first screen module 2 consistent with the arc-shaped path of the arc-shaped gear segment. This can better adapt to the contour design of the main body 1 of the device and avoid interference between the first screen module 2 and the main body 1 of the device during rotation. It solves the problem of space occupation caused by the linear or excessive rotation trajectory when using a complete circular gear. Especially when the main body 1 of the device is small, it can make full use of the internal space and meet the needs of miniaturization of the device in the storage state.

[0051] The meshing teeth 431 on the outer circumference of the arc-shaped gear segment cooperate with the first transmission component 42 to form a continuous and stable power transmission path, improving angle control accuracy and avoiding angle deviation when the first screen module 2 switches states due to transmission instability. This ensures that the first screen module 2 can stably face the first direction during operation. Furthermore, the arc-shaped gear segment only needs to cover the rotation angle required for the first screen module 2 to switch from the stored state to the working state, eliminating the need for a complete circular gear with full circumference teeth. This reduces the material usage and processing area of ​​the gear components, simplifies the processing technology of the transmission gear component 43, and lowers manufacturing costs. Moreover, its connection method, where one end is fixed to the first screen module 2 along the arc length direction, eliminates the need for complex transition structures, simplifying assembly steps, improving production efficiency, and reducing the additional volume of connecting parts, further adapting to the miniaturization design of the equipment.

[0052] According to one embodiment of this application, such as Figure 5 and Figure 7 As shown, the center 432 of the arc-shaped gear segment is located outside the first screen module 2.

[0053] The center 432 of the arc-shaped gear segment is located outside the first screen module 2, so that when the first screen module 2 rotates together with the arc-shaped gear segment, the center of the rotation trajectory does not occupy the internal space of the first screen module 2 itself. There is no need to reserve an installation area for the rotation axis inside the first screen module 2, which avoids the problem of increased screen module size or crowded internal component layout caused by the center being set inside the first screen module 2. This effectively controls the overall size of the first screen module 2, thereby adapting to the miniaturization design requirements of the main body 1 of the device, ensuring that the overall size of the device can be further reduced in the storage state, and improving portability.

[0054] Meanwhile, with the center located outside the first screen module 2, the rotation path of the arc-shaped gear segment can better fit the internal spatial layout of the device body 1, avoiding interference with components such as the first flip motor 41 and the first transmission component 42 inside the device body 1. This ensures smoother power transmission between the components of the first rotating mechanism 4, reduces rotational jamming or component wear caused by spatial interference, and improves the stability and smoothness of the switching state of the first screen module 2. Furthermore, the feature of not occupying the flip space also reserves more space for the layout of other functional modules inside the device body 1 (such as the battery and translation motherboard), facilitating future expansion of device functions without increasing the overall size.

[0055] According to one embodiment of this application, such as Figure 2 and Figure 6 As shown, the first screen module 2 includes a first screen 21 and a shielding bracket 22; wherein, the shielding bracket 22 is connected to the back of the first screen 21 to shield the first rotating mechanism 4.

[0056] The first screen module 2 is connected to a shielding bracket 22 on the back of the first screen 21, which can cover and shield the first rotating mechanism 4, preventing the first rotating mechanism 4 from being exposed to the outside of the device or in the gap between the first screen module 2 and the device body 1. This solves the problem of a cluttered appearance caused by the exposed rotating mechanism. Especially when the first screen module 2 is in working condition, the internal transmission components cannot be seen from the outside of the device, which can maintain the simplicity and integrity of the overall appearance of the device. This is consistent with the design intention of the first screen module 2 forming the appearance of the device body 1 when stored, and further enhances the visual aesthetics of the product.

[0057] Meanwhile, the shielding bracket 22 can provide physical protection for the first rotating mechanism 4, reducing the entry of external dust and impurities into the first rotating mechanism 4, and preventing transmission jamming and component wear caused by dust adhering to the output shaft of the first flip motor 41, the meshing teeth 431 of the first transmission component 42, or the arc gear segment.

[0058] According to one embodiment of this application, such as Figure 8 As shown, the second screen module 3 includes a second screen 31 and a screen bracket 32. The screen bracket 32 ​​is used to mount the second screen 31, and the screen bracket 32 ​​includes a sleeve 321 connected to the bottom of the second screen 31. The sleeve 321 forms the rotation axis of the second screen 31.

[0059] The second screen module 3 is mounted on the second screen 31 via a screen bracket 32, and the sleeve 321 of the screen bracket 32 ​​forms the rotation axis of the second screen 31. This eliminates the need for a separate rotation axis component for the second screen 31, reducing the number of parts in the second screen module 3, simplifying the overall structure, and lowering the complexity of parts processing and assembly, thereby controlling manufacturing costs. The sleeve 321 connects to the bottom of the second screen 31, enabling stable switching between the retracted and operational states, avoiding screen tilting and jamming caused by improper rotation axis positioning, and improving the stability of the second screen 31 during rotation.

[0060] The sleeve 321 forms a rotating shaft, eliminating the need to reserve space for the rotating shaft installation on the side or front of the second screen 31. This does not compress the display area of ​​the second screen 31, nor does it create a protruding structure at the edge of the second screen 31, ensuring that the second screen 31 can maintain a complete display area. At the same time, it adapts to the fitting requirements of the second screen 31 with the main body of the device 1 and the first screen module 2 in the storage state, reducing the overall volume of the device after storage and meeting the requirements of portable design.

[0061] According to one embodiment of this application, such as Figure 9 and Figure 10 As shown, the electronic device also includes a second rotating mechanism 5 disposed at the first end of the sleeve 321; the second rotating mechanism 5 includes a second flip motor 51, a first flip base 52, and a second transmission assembly 53, wherein the second flip motor 51 is fixedly installed in the sleeve 321; the first flip base 52 is fixedly installed on the device body 1; the second transmission assembly 53 is connected to the output end of the second flip motor 51, and the output end of the second transmission assembly 53 extends out of the sleeve 321 and is fixedly connected to the first flip base 52, so as to drive the sleeve 321 to rotate relative to the device body 1. The second flip motor 51 can be a stepper motor with an effective maximum outer diameter of 18mm.

[0062] The second rotating mechanism 5 fixes the second flip motor 51 inside the sleeve 321, making full use of the hollow space of the sleeve 321. There is no need to reserve an additional installation area for the second flip motor 51 inside the main body of the equipment, reducing the internal space occupied by the main body of the equipment, adapting to the design requirements of overall miniaturization of electronic equipment, while avoiding the risk of appearance clutter or collision damage caused by exposed motor, protecting the second flip motor 51 from external dust and impurities, and extending the service life of the motor.

[0063] The second transmission component 53 connects to the output end of the second flip motor 51 and extends out through the sleeve 321 to connect with the first flip base 52 fixed to the main body 1 of the device, forming a power transmission path of "motor-transmission structure-fixed base": when the second flip motor 51 is running, the power is transmitted to the first flip base 52 through the second transmission component 53. The first flip base 52 is fixed to the main body 1, and the reaction force drives the sleeve 321 (and the second screen 31 connected to the sleeve 321) to rotate relative to the main body 1, realizing the switching of the second screen module 3 between the storage state and the working state. This transmission method does not require complex adapter parts, the power transmission is direct and the loss is small, avoiding the problems of rotation jamming and angle deviation caused by multiple component adapters, and improving the stability and smoothness of the rotation process of the second screen 31.

[0064] The assembly relationships between the components of the second rotating mechanism 5 (the second flipping motor 51 and the second transmission assembly 53) and the sleeve 321 and the first flipping base 52 are clear. During assembly, it is only necessary to position the sleeve 321 in the corresponding area of ​​the main body 1 and then connect the second transmission assembly 53 to the first flipping base 52 to complete the installation. There is no need for complicated calibration steps, which improves the production and assembly efficiency of the second screen module 3. At the same time, the built-in structure of the motor makes the overall integration of the second rotating mechanism 5 and the second screen module 3 higher, without adding extra volume to the second screen module 3. This ensures that the second screen 31 can fit tightly against the main body 1 when stored, further reducing the overall thickness of the device after storage, which meets the requirements of portable use.

[0065] In practical applications, a reduction gearbox can be installed in the second transmission component 53 to adjust the output speed of the second flip motor 51, reduce the speed transmitted to the second screen 31, make the rotation process of the second screen 31 smoother, and avoid the impact when the second screen module 3 switches states due to excessive motor speed.

[0066] The second rotating mechanism 5 may also include a motor fixing block 54, which is a metal structural component for fixing the second rotating motor 51.

[0067] According to one embodiment of this application, such as Figure 9 and Figure 11 As shown, the electronic device also includes a third rotating mechanism 6 disposed at the second end of the sleeve 321; the third rotating mechanism 6 includes a flip connecting shaft 61, a second flip base 62, and a bearing 63. The flip connecting shaft 61 is fixed to the second end of the sleeve 321; the second flip base 62 is fixedly mounted on the device body 1; the bearing 63 is disposed between the flip connecting shaft 61 and the second flip base 62, allowing the flip connecting shaft 61 to rotate relative to the second flip base 62.

[0068] The third rotating mechanism 6 cooperates with the second rotating mechanism 5 at the first end of the sleeve 321 to form a symmetrical support structure at both ends of the sleeve 321. This effectively distributes the weight load of the second screen module 3, preventing tilting, swaying, or rotation axis deviation caused by unilateral force when the second screen 31 rotates around the sleeve 321. This significantly improves the stability of the second screen 31 during rotation, ensuring that the second screen 31 always maintains the preset trajectory when switching between the storage state and the working state, and solving the problems of rotation jamming and angle deviation that are prone to occur with unilateral support.

[0069] The bearing 63 is located between the flip connecting shaft 61 and the second flip base 62, which can convert the sliding friction between the two into rolling friction, greatly reducing the frictional resistance during relative rotation, making the rotation operation of the second screen 31 smoother. At the same time, the reduction of frictional resistance can reduce the wear of the flip connecting shaft 61 and the second flip base 62, extend their service life, avoid the increase of component gap and the decrease of rotational accuracy caused by long-term friction, and the noise generated by rolling friction is lower, improving the quietness of the equipment during use.

[0070] The third rotating mechanism 6 has a relatively simple structure with few parts and no need for complex transmission components. During assembly, it is only necessary to fix the flip connecting shaft 61 onto the sleeve 321 and install the bearing 63 and the second flip base 62, which simplifies the overall assembly process of the second screen module 3 and reduces production complexity. Moreover, each component is small in size and can be tightly integrated between the second end of the sleeve 321 and the main body of the device 1 without occupying additional internal space of the device or increasing the overall volume of the electronic device after storage, which is consistent with the design requirements of miniaturization and portability of the device.

[0071] It should be noted that the aforementioned first rotating mechanism 4, second rotating mechanism 5 and third rotating mechanism 6 can be either an automated structure driven by a motor or a non-automated structure operated manually by an operator.

[0072] According to one embodiment of this application, such as Figure 11 As shown, the third rotating mechanism 6 also includes a damping spring 64 and a damping plate 65. The damping spring 64 is disposed inside the second flipping base 62, so that the flipping connecting shaft 61 and the second flipping base 62 are close together in the axial direction of the flipping connecting shaft 61; the damping plate 65 is disposed between the flipping connecting shaft 61 and the second flipping base 62 in the axial direction of the flipping connecting shaft 61 to increase the frictional force when the flipping connecting shaft 61 and the second flipping base 62 rotate relative to each other.

[0073] The damping spring 64 is disposed inside the second flip base 62 and can apply axial preload to the flip connecting shaft 61, so that the flip connecting shaft 61 and the second flip base 62 are closely close in the axial direction, eliminating the axial gap between them, avoiding the up-and-down movement caused by axial loosening when the second screen 31 rotates around the sleeve 321, ensuring that the second screen 31 always maintains a stable radial trajectory during rotation, solving the "axial sway" problem that is prone to occur in single-sided or double-sided rotation mechanisms, and improving the structural stability of the second screen module 3.

[0074] A damping plate 65 is axially positioned between the flip connecting shaft 61 and the second flip base 62. Its coefficient of friction increases the frictional force during relative rotation, creating a stable damping effect. This damping effect prevents the second screen 31 from rapidly flipping due to inertia during rotation, allowing it to slowly remain at any preset angle (rather than being fixed in a stored or working state). Users can flexibly adjust the tilt angle of the second screen 31 according to their viewing angle (such as standing or sitting) without additional manual fixing, improving usability. Simultaneously, the damping force buffers the impact of external touches, preventing angle shifts or component collisions caused by accidental rapid flipping of the second screen 31, protecting the second screen 31 and its internal structure.

[0075] The combined structure of damping spring 64 and damping plate 65 does not require complex electronic control components. Axial fastening and radial damping functions can be achieved solely through mechanical structure. The parts are low-cost and easy to assemble. It does not increase the size and weight of the third rotating mechanism 6, and is suitable for the miniaturization requirements of the equipment. Both are hidden between the second flip base 62 and the flip connecting shaft 61, and are not exposed on the appearance of the equipment, which does not affect the overall simplicity of the equipment. At the same time, the mechanical damping structure has high reliability and is not prone to failure due to circuit failure, which extends the service life of the third rotating mechanism 6 and reduces the frequency of equipment maintenance.

[0076] According to one embodiment of this application, such as Figure 11 As shown, the third rotating mechanism 6 also includes a retaining ring 66 and a baffle plate 67. A mounting groove 611 is provided on the outer circumferential surface of the flip connecting shaft 61, and the retaining ring 66 is disposed in the mounting groove 611. The baffle plate 67 is sleeved on the flip connecting shaft 61, with one side connected to (e.g., abutting against) the retaining ring 66 and the other side connected to (e.g., abutting against) the first end of the damping spring 64. A connecting part 621 is provided inside the second flip base 62, which is used to connect (e.g., abutting against) the second end of the damping spring 64. A boss 612 is provided on the flip connecting shaft 61, and a damping plate 65 is disposed between the boss 612 and the bearing 63.

[0077] The flip-connecting shaft 61 fixes the retaining ring 66 through the mounting groove 611. The retaining ring 66 can axially limit the baffle 67 sleeved on the flip-connecting shaft 61, preventing the baffle 67 from moving axially along the flip-connecting shaft 61 during the compression and rebound of the damping spring 64. This ensures that the baffle 67 always stably abuts against the first end of the damping spring 64, avoiding the problem of the damping spring 64 being shifted due to the displacement of the baffle 67, and the instability of the preload. This provides a reliable axial positioning base for the damping spring 64, thereby ensuring the axial fit between the flip-connecting shaft 61 and the second flip base 62, eliminating the axial gap between them, and reducing the up-and-down movement of the second screen 31 when it rotates.

[0078] The connection 621 between the baffle 67 and the second flip base 62 abuts against the damping spring 64 from both ends to ensure that the spring can continuously output a stable axial preload and improve the structural stability of the second screen module 3 when it rotates.

[0079] The boss 612 on the flip-connecting shaft 61 provides precise radial positioning for the damping plate 65, stably confining it between the boss 612 and the bearing 63. This prevents the damping plate 65 from shifting radially or falling off during the rotation of the flip-connecting shaft 61, ensuring stable contact between the damping plate 65 and the flip-connecting shaft 61 and the bearing 63. This guarantees consistent friction during rotation and prevents weakening or failure of the damping effect due to displacement of the damping plate 65. This positioning method eliminates the need for additional fixing structures, utilizing the boss 612 on the flip-connecting shaft 61 itself to fix the damping plate 65. This reduces the number of parts, simplifies the overall structure of the third rotating mechanism 6, and does not occupy additional internal space, making it suitable for miniaturized equipment designs.

[0080] Because the damping plate 65 has a large coefficient of friction, the friction between the damping plate 65 and the boss 612, and between the damping plate 65 and the bearing 63, increases, making the rotation of the second screen module 3 more stable.

[0081] According to one embodiment of this application, such as Figure 2 As shown, the surface of the main body 1 of the device is provided with a first mounting empty area 11 and a second mounting empty area 12, and the second mounting empty area 12 is disposed on the bottom wall of the first mounting empty area 11; the first screen module 2 is housed in the first mounting empty area 11, and the second screen module 3 is housed in the second mounting empty area 12.

[0082] The main body of the device 1 has a first mounting space 11 and a second mounting space 12 set in a layered manner on its surface. This allows the first screen module 2 and the second screen module 3 to be embedded into the corresponding spaces when stored, forming a "layered" storage structure. This avoids excessive increase in the horizontal size of the device caused by the two screen modules being stacked on the same plane. It effectively controls the overall volume of the electronic device in the stored state, solves the problem of poor portability caused by unreasonable storage layout of traditional dual-screen devices, and is more suitable for mobile use scenarios such as cross-border travel and outdoor communication.

[0083] The second mounting empty area 12 is set on the bottom wall of the first mounting empty area 11, so that the first screen module 2 can be stored and cover the second mounting empty area 12, forming physical protection for the second screen module 3 stored in the second mounting empty area 12, avoiding direct collision and scratching of the display surface of the second screen 31 by external objects, and reducing the risk of damage to the second screen 31 due to accidental contact; correspondingly, a protective layer (such as tempered glass) can be set on the first screen module 2 located on the outside, which can directly form a physical barrier on the outer surface of the first screen 21, resisting direct scratches from external objects (such as keys, coins, and desktop clutter), avoiding scratches and wear on the surface of the first screen 21, protecting the integrity of the display surface of the first screen 21, solving the problem that the first screen module 2, as an exterior surface, is easily damaged due to long-term exposure, and extending the service life of the first screen 21.

[0084] Meanwhile, the outer surface of the first screen module 2 can form the appearance of the main body 1 of the device, eliminating the need for an additional independent shell, simplifying the overall structure of the device, reducing manufacturing costs, and maintaining the integrity and simplicity of the device's appearance.

[0085] The dedicated installation space provides precise storage positioning for the first screen module 2 and the second screen module 3, preventing misalignment or offset during storage. This ensures a flat surface on the device after storage and avoids inconvenience caused by protruding screen modules (such as jamming when putting them into a backpack). Simultaneously, the fixed storage position makes the rotation path of the screen modules clearer when switching to working mode, reducing the likelihood of interference with other components of the main body 1, improving the smoothness of mode switching, and further optimizing the user experience.

[0086] According to one embodiment of this application, such as Figure 2 As shown, the bottom wall of the first installation empty area 11 is also provided with a through hole 111 for the transmission gear component 43 to pass through.

[0087] The through hole 111 on the bottom wall of the first installation space 11 provides a through channel for the transmission gear component 43, so that one end of the transmission gear component 43 can be fixed to the first screen module 2 and the other end can extend into the device body 1 and cooperate with the first transmission component 42. This avoids the transmission gear component 43 being unable to transmit power due to being blocked by the bottom wall of the first installation space 11, and solves the spatial interference problem between the "storage requirement of the first screen module 2" and the "transmission requirement of the transmission gear component 43". This ensures that the first screen module 2 can be smoothly stored in the first installation space 11 without affecting the meshing transmission between the transmission gear component 43 and the first transmission component 42.

[0088] The through hole 111 can limit the rotation trajectory of the transmission gear component 43, preventing radial offset when the transmission gear component 43 rotates with the first screen module 2. This ensures that it always maintains stable meshing with the first transmission component 42, reducing problems such as rotational jamming and power transmission interruption caused by meshing misalignment, and improving the smoothness of switching between the first screen module 2 in the storage state and the working state. At the same time, the through hole 111 allows most of the structure of the transmission gear component 43 to be hidden inside the main body 1 of the device, requiring only a portion to pass through the bottom wall to connect with the first screen module 2. This reduces the exposed area of ​​the transmission gear component 43, reduces damage to the component from external collisions and dust erosion, and extends the service life of the transmission gear component 43.

[0089] The via 111 does not require additional changes to the overall size of the first mounting area 11. The component avoidance and transmission adaptation can be achieved simply by opening the bottom wall. It does not affect the storage space of the first mounting area 11 for the first screen module 2, which meets the design requirements of miniaturization of the main body 1. Moreover, the processing technology of the via 111 is simple and can be completed simultaneously with the processing of the first mounting area 11, without adding extra production steps and controlling manufacturing costs.

[0090] The electronic device provided in this application embodiment has a main body 1 made of aerospace aluminum by stamping, with a sandblasting and anodizing process added to the surface; the two large screens are a 10.95-inch main screen (first screen 21) and a 9-inch secondary screen (second screen 31), both with touch function, and can be electrically controlled to unfold and fold the main screen and secondary screen with one button. The electronic device is equipped with two 10W high-power speakers, distributed in the front and rear corners of the main body 1, the sound emission is satisfactory for users in both directions, and there is no difference in volume.

[0092] The screen rotation start button 71 is an electronic button for one-button start. When the button is pressed, the first screen module 2 is opened electrically first, and after the first screen module 2 is fully opened, the second screen module 3 is opened electrically. The interval between these openings is controlled by the program. The volume control button 73 is used to adjust the speaker volume. The fingerprint recognition button 74 enhances the security of the electronic device. The electronic device has a user identification function and can use fingerprint recognition, which can recognize up to one hundred fingerprints. The front speaker housing 75 serves as the sound grille for the front speaker BOX81 (cabinet). It can be made of plastic and corresponds to the sound output position of the front speaker. The speaker is a 10W high-volume speaker. The rear speaker housing 76 serves as the sound grille for the rear speaker BOX82. It can also be made of plastic and corresponds to the sound output position of the rear speaker. The speaker is a 10W high-volume speaker. The left external interface array 77 of the motherboard serves as the external interface terminal of the motherboard. Related interface terminals are distributed on both sides of the main body 1. The interface terminals include power interfaces, data interfaces, network ports, audio interfaces, etc. The microphone array (MIC) is a multi-MIC array, distributed in three directions: four microphones on each side and six microphones at the front (i.e., the center MIC array 80), for a total of 14 microphones. This large three-way distribution increases the pickup range and enhances sound reception. The rear speaker BOX 82 is a 10W speaker in a BOX-type enclosure, providing high power and volume. The front speaker BOX 81 is also a 10W speaker in a BOX-type enclosure, providing high power and volume. The main circuit board 83 controls the overall electronic performance of the device. Internally riveted long screw posts 85 and internally riveted short screw posts 86 are used for mounting components. Welded sheet metal 84 increases the strength of the main chassis casing assembly 72 and reduces processing costs.
