[0045] The realization of the objectives, functional features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] Optionally, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Optionally, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which needs to be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0048] It should be understood that in the description of this application, terms such as "inner" and "outer" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0049] Furthermore, optionally, in the description of this application, unless otherwise expressly 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; and they can refer to the internal connection 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.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0052] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0053] In some solutions, the stretching or contraction of the housing components causes the flexible display to stutter during movement, resulting in a poor user experience. Furthermore, the mechanism occupies significant stacking space, leading to low stacking efficiency.

[0054] Therefore, the housing assembly and smart terminal provided in this application, through the design of the transmission assembly, enable the flexible display screen to smoothly extend and retract when the first housing and the second housing slide relative to each other. The structure occupies little space, and the structural principle is simple, reliable, and practical. Creases are not easily formed on the flexible display screen. The design of the support assembly, in which the sliding groove and the arc-shaped support part cooperate to ensure the smooth transition of the flexible display screen during movement, improves the smoothness of movement, reduces the risk of jamming or blockage, and thus helps to improve the user's experience of using the smart terminal.

[0055] To facilitate understanding, the application scenarios applicable to the embodiments of this application will be described below.

[0056] The housing component provided in this application can be applied to a smart terminal, which can be of various forms. For example, the smart terminal described in this application may include smart terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0057] The following description will use a smart terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0058] Based on the structure of the smart terminal and the housing component in the smart terminal described above, various embodiments of this application are proposed.

[0059] First Embodiment

Figure 2 This is a cross-sectional view from a first-view perspective of the flexible display screen in the stretched state of the smart terminal in this embodiment of the application.

Figure 4 for Figure 3 A magnified view of a section at point I. Figure 5 This is a schematic diagram of the assembly of the slider and support components in the embodiments of this application.

[0061] like Figures 1 to 5 As shown, this application embodiment provides a housing assembly 100 to support a flexible display screen 220. The housing assembly 100 includes a first housing 110, a second housing 120, a transmission assembly 130, and a support assembly 140. When the first housing 110 and the second housing 120 slide relative to each other, the transmission assembly 130 drives the flexible display screen 220 to stretch or retract. The support assembly 140 includes a support member 141, which is disposed on the flexible display screen 220. The support member 141 has an arc-shaped support portion 1411. The second housing 120 is provided with a sliding groove 1211. The arc-shaped support portion 1411 is configured to slide within the sliding groove 1211 when the flexible display screen 220 moves.

[0062] Through the above-mentioned configuration, namely the design of the transmission component 130, the flexible display screen 220 can be smoothly extended and retracted when the first housing 110 and the second housing 120 slide relative to each other. The structure occupies little space, and the structural principle is simple, reliable and practical. Creases are not easily formed on the flexible display screen 220. The design of the support component 140, in which the sliding groove 1211 and the arc-shaped support part 1411 cooperate to ensure the smooth transition of the flexible display screen 220 during movement, improves the smoothness of movement, reduces the risk of jamming or blockage, and thus helps to improve the user's experience of using the smart terminal 200.

[0063] The housing assembly 100 provided in this application embodiment is used to support the flexible display screen 220, which can be bent under the action of external force.

[0064] In some examples, the first housing 110 and the second housing 120 may be metal parts, and the material may include one or more of copper, iron, aluminum, tin, and lead.

[0065] In some examples, the first housing 110 and the second housing 120 may also be made of plastic. During injection molding, molten plastic is injected into a plastic product mold under pressure, and then cooled and solidified to obtain the desired plastic part.

[0066] Optionally, the materials of the first housing 110 and the second housing 120 may be the same or different. This embodiment of the present invention does not impose too many restrictions on the materials of the first housing 110 and the second housing 120.

Figure 7 This is a structural diagram of the flexible display screen in the retracted state of the smart terminal in an embodiment of this application, viewed from a third-person perspective. Figure 8 This is a structural schematic diagram of the flexible display screen in the housing assembly of this application in the retracted state from a second perspective. Figure 9 This is a structural schematic diagram of the flexible display screen in the housing assembly in the retracted state, as shown in a third-person perspective, according to an embodiment of this application. Figure 10 This is a structural schematic diagram of the flexible display screen in the smart terminal of the embodiment of this application, viewed from a second perspective, in a stretched state. Figure 11 This is a structural schematic diagram of the flexible display screen in the smart terminal of the embodiment of this application, viewed from a third-person perspective, in a stretched state. Figure 12 This is a structural schematic diagram of the flexible display screen in the smart terminal of the embodiment of this application, viewed from a fourth perspective, in a stretched state. Figure 13 This is a structural schematic diagram of the flexible display screen in the shell assembly under a stretched state in an embodiment of this application, viewed from a second perspective.

[0068] like Figure 2 , Figures 10 to 13 As shown, the first housing 110 and the second housing 120 slide relative to each other, so that the flexible display screen 220 supported by the first housing 110 and the second housing 120 is in a stretched state. That is, when the first housing 110 and the second housing 120 are both unfolded, the flexible display screen 220 is in a stretched state, and the smart terminal 200 is in large screen display mode.

[0069] like Figure 1 , Figures 6 to 9 As shown, when either the first housing 110 or the second housing 120 retracts, the flexible display screen 220 is in a retracted state. That is, part of the flexible display screen 220 retracts into the housing assembly 100, at which point the smart terminal 200 is in a small-screen display mode. The smart terminal 200 occupies less space, and the built-in design of the flexible display screen 220 also provides protection for it.

[0070] The flexible display screen 220 is effectively supported during expansion and contraction via the arc-shaped support portion 1411 in the support assembly 140, reducing bending or deformation caused by lack of support and thus improving the lifespan and reliability of the display screen. This design allows the flexible display screen 220 to retract into the housing when not in use, thereby reducing the space occupied by the device.

[0071] When the display is retracted, the housing assembly 100 provides protection against damage to the display from external impacts or scratches.

[0072] By providing reliable support and smooth operation, users can have a better experience when using the device, especially in scenarios where the display needs to be extended or retracted frequently, such as in foldable phones or expandable tablets.

[0073] In some embodiments, the flexible display screen 220 is used to display images.

[0074] Optionally, the flexible display screen 220 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MID) display screen, a micro organic light-emitting diode (MID) display screen, a micro organic light-emitting diode (MID) display screen, or a quantum dot light-emitting diode (QLED) display screen.

[0075] Optionally, there are at least two support components 140, which are spaced apart along the direction of movement of the flexible display screen 220.

[0076] By providing at least two support components 140 at intervals along the moving direction of the flexible display screen 220, uniform support for the flexible display screen 220 can be achieved, which can effectively prevent local bending or deformation of the flexible display screen 220 during the extension and retraction process, and improve the overall flatness and structural stability of the flexible display screen 220.

[0077] Since the support assembly 140 slides within the sliding groove 1211, the spacing between at least two support assemblies 140 can reduce friction and wear on each support assembly 140, thereby extending the service life of the assembly and maintaining smooth operation.

[0078] The arrangement of at least two support components 140 can distribute the stress and load of the flexible display screen 220 during the expansion and contraction process, which helps to improve the structural strength of the flexible display screen 220 and reduce the risk of damage caused by excessive force at a single point.

[0079] like Figure 3 and Figure 4 As shown, optionally, the support assembly 140 also includes a base 142, which is connected to the back of the flexible display screen 220, and the support member 141 is disposed on the base 142.

[0080] The base 142 provides a stable connection platform to fix the support 141 to the back of the flexible display screen 220, which can ensure that the support 141 remains stable during the extension and retraction of the flexible display screen 220, thereby improving the overall stability of the flexible display screen 220.

[0081] Integrating the support component 141 into a single module via the base 142 simplifies the installation and maintenance process. Replacement or repair can be performed on individual modules more easily without requiring extensive disassembly of the entire display structure.

[0082] The presence of the base 142 increases the overall structural strength of the support assembly 140, enabling it to better withstand the mechanical stress and external impact generated by the display during operation.

[0083] In some embodiments, the base 142 may be a strip structure, a strip block, or a plate.

[0084] Optionally, the support member 141 also has a connecting portion 1412, the first end of which is connected to the side wall of the base 142.

[0085] Optionally, the arc-shaped support portion 1411 is connected to the second end of the connecting portion 1412 and protrudes from the end of the flexible display screen 220.

[0086] At least two connecting portions 1412 have their first ends connected to the side wall of the base 142, providing a stable support point and helping to enhance the structural stability of the entire support assembly 140, ensuring that the curved support portion 1411 remains stable during operation. Furthermore, the curved support portion 1411 protrudes from the end of the flexible display screen 220, providing additional protection to prevent the display screen from directly contacting other components during extension and retraction, thereby reducing wear and potential damage.

[0087] Optionally, the connecting part 1412 is a plate-shaped bent part.

[0088] The plate-shaped bent component possesses high structural strength and rigidity, effectively supporting the connection between the curved support 1411 and the base 142. The plate-shaped bent component can optimize force transmission and distribution through its geometry, reducing localized stress concentration and lowering the risk of damage.

[0089] In some embodiments, sheet-like bent parts can typically be manufactured using stamping and bending processes, which are relatively simple and low-cost, helping to reduce production costs and improve manufacturing efficiency.

[0090] Optionally, the shape and size of the plate-shaped bending component can be adjusted according to specific design requirements to adapt to different equipment and application scenarios.

[0091] Optionally, the arc-shaped support 1411 is a cylindrical structural component.

[0092] The cylindrical structural component possesses excellent geometric stability and strength, providing reliable support and ensuring the flexible display screen 220 remains stable during expansion and contraction, reducing the possibility of swaying and deformation. The smaller contact surface of the cylindrical structural component within the sliding groove 1211 effectively reduces friction, allowing the arc-shaped support portion 1411 to move more smoothly within the sliding groove 1211.

[0093] Optionally, the connecting part 1412 and the arc-shaped support part 1411 are integrally formed structural components.

[0094] The unibody design eliminates the seams or connection points between the connecting part 1412 and the arc-shaped support part 1411, thereby reducing potential weaknesses and improving the overall structural strength and stability. Due to the absence of connection points or welds, the unibody structure offers greater durability over long-term use, reducing failures caused by fatigue or wear. The absence of seams also provides better protection against dust and moisture infiltration, thus improving the equipment's environmental adaptability.

[0095] In some embodiments, a one-piece molding process (such as injection molding, die casting, or 3D printing) can reduce manufacturing steps and assembly complexity, thereby reducing production costs and improving production efficiency.

[0096] Optionally, the support assembly 140 also includes a connector, through which the connecting part 1412 and the base 142 are connected.

[0097] By using connectors, the connection between the connector 1412 and the base 142 becomes more flexible. This flexibility allows for fine-tuning during design and assembly to adapt to different equipment requirements and operating conditions. The use of connectors makes the connection between the connector 1412 and the base 142 more modular. When maintenance or replacement is required, individual components can be more easily disassembled and replaced without large-scale disassembly of the entire support structure.

[0098] In some embodiments, connectors can be manufactured in a standardized manner, simplifying the assembly process and improving production efficiency. This modular design can also reduce assembly errors and improve product consistency and reliability.

[0099] In other embodiments, the connector may be designed to have a certain degree of elasticity or cushioning properties to absorb and mitigate vibrations and shocks generated during operation, thereby protecting the flexible display screen 220 and other components.

[0100] Optionally, the second housing 120 is provided with a slider 121, which is located at the end of the second housing 120; a sliding groove 1211 is provided on the slider 121.

[0101] The slider 121 provides a special structure to accommodate the sliding groove 1211, thereby ensuring the stability of the arc-shaped support 1411 during the sliding process, reducing shaking and jamming, and improving the smoothness of operation.

[0102] Alternatively, the slider 121 can be maintained or replaced separately as needed without affecting the overall structure of the second housing 120.

[0103] In some embodiments, there are two sliders 121, which are located at opposite ends of the second housing 120, and the extending direction of the sliders 121 is consistent with the moving direction of the second housing 120.

[0104] Optionally, the first housing 110 is connected to the first end of the flexible display screen 220; the transmission assembly 130 includes a flexible transmission member 133, a first rotating member 131 and a second rotating member 132, the first rotating member 131 and the second rotating member 132 are rotatably disposed on the second housing 120; the second end of the flexible display screen 220 is wrapped around the outer periphery of the first rotating member 131, the flexible transmission member 133 is connected between the second end of the flexible display screen 220 and the first housing 110, the flexible transmission member 133 is wrapped around the second rotating member 132, when the first housing 110 and the second housing 120 slide relative to each other, the flexible transmission member 133 drives the flexible display screen 220 to stretch or retract.

[0105] Optionally, both the first rotating member 131 and the second rotating member 132 can rotate relative to the second housing 120, and both the first rotating member 131 and the second rotating member 132 can be optionally fixed on the second housing 120 to ensure the stability of their installation.

[0106] The structure and size of the first rotating member 131 and the second rotating member 132 are not limited in this embodiment and can be adjusted according to the actual situation.

[0107] Optionally, the flexible transmission component 133 can be a traction rope with a certain elasticity.

[0108] Optionally, the flexible transmission component 133 can be a nylon rope, which is a rope made of nylon material, formed by winding nylon fibers through a series of winding processes.

[0109] Optionally, the flexible display screen 220 is wrapped around the outer periphery of the first rotating member 131, and the flexible transmission member 133 is wrapped around the outer periphery of the second rotating member 132. The flexible transmission member 133 is connected between the second end of the flexible display screen 220 and the first housing 110. When the retraction amount of the flexible display screen 220 matches the movement amount of the flexible transmission member 133, the area occupied by the transmission component 130 can be reduced while ensuring that the flexible display screen 220 is stretched or retracted. The overall structure is relatively simple and the cost is reduced.

[0110] Optionally, through the design of the transmission component 130, the flexible transmission component 133, the first rotating component 131, and the second rotating component 132 can be matched to realize the unfolding or retraction of the flexible display screen 220. When the flexible display screen 220 switches from the unfolded state to the retracted state, or vice versa, the flexible transmission component 133 is always in a taut state, which makes the tension on the flexible display screen 220 consistent. The structure occupies little space, and the structural principle is simple, reliable, and practical. Creases are not easily formed on the flexible display screen 220, which can reduce the damage rate of the flexible display screen 220 and improve the service life of the transmission component 130, thereby improving the user's experience of the smart terminal 200.

[0111] In some embodiments, the amount of movement of the flexible transmission member 133 is consistent with the amount of stretching or contraction of the flexible display screen 220.

[0112] The amount of movement of the flexible transmission component 133 is consistent not only with the amount of stretching of the flexible display screen 220, but also with the amount of retraction of the flexible display screen 220.

[0113] Optionally, the first housing 110 slides relative to the second housing 120. When the first housing 110 retracts, the flexible transmission member 133 moves towards the second housing 120 relative to the first housing 110, causing the end of the flexible transmission member 133 to lengthen. The reduction in the size of the flexible screen on the first housing 110 is equal to the lengthening of the end of the flexible transmission member 133 on the first housing 110.

[0114] When the first housing 110 extends, the flexible transmission member 133 moves towards the second housing 120 relative to the first housing 110, pushing the end of the flexible transmission member 133 to shorten. The lengthening of the flexible screen on the first housing 110 is equal to the shortening of the end of the flexible transmission member 133 on the first housing 110.

[0115] In some embodiments, when the flexible display screen 220 retracts and the second housing 120 is located outside the first housing 110, the first rotating member 131 and the second rotating member 132 rotate in the same direction.

[0116] like Figure 2 , Figures 10 to 13 As shown, the movement trajectories of the flexible display screen 220 and the flexible transmission component 133 conform to the G-shape.

[0117] Optionally, when the flexible display screen 220 switches from being stretched to being retracted, the smart terminal 200 is in small screen display mode. If the second housing 120 is located outside the first housing 110, and the first rotating member 131 and the second rotating member 132 rotate in the same direction, that is, the first rotating member 131 and the second rotating member 132 both rotate counterclockwise.

[0118] Optionally, when the flexible display screen 220 switches from retracted to stretched, the smart terminal 200 is in large-screen display mode. The first housing 110 moves from being located inside the second housing 120 to being flush with the second housing 120, and the first rotating member 131 and the second rotating member 132 rotate in the same direction, that is, the first rotating member 131 and the second rotating member 132 both rotate clockwise.

[0119] Optionally, the housing assembly 100 further includes a drive member 150 and a first support member 160; the first support member 160 is movably disposed on the first housing 110, and the first support member 160 has a rotating end and a moving end. When the driving end of the drive member 150 drives the rotating end, the moving end provides a pushing force to the second housing 120 so that the second housing 120 slides relative to the first housing 110.

[0120] The drive member 150 drives the rotating end of the first support member 160 through its drive end, thereby providing a pushing force to the second housing 120. Through precise control of the drive member 150, precise adjustment of the sliding of the second housing 120 relative to the first housing 110 can be achieved. The design of the first support member 160 optimizes the force transmission path; the cooperation between the rotating end and the moving end ensures effective force transmission, reduces energy loss, and improves drive efficiency.

[0121] In some embodiments, the drive element 150 may be a drive motor.

[0122] Optionally, the first support member 160 includes a first movable frame 161 and a second movable frame 162; when the driving end of the driving member 150 drives the rotating end of the first movable frame 161 and the rotating end of the second movable frame 162, the moving end of the first movable frame 161 and the moving end of the second movable frame 162 both provide a pushing force to the second housing 120, and the moving end of the first movable frame 161 and the moving end of the second movable frame 162 move towards or away from each other.

[0123] By simultaneously driving the moving ends of the first movable frame 161 and the second movable frame 162, a more uniform pushing force can be provided to the second housing 120, which helps to reduce tilting or asymmetrical movement of the second housing 120 during sliding and improves operational stability. The moving ends of the first movable frame 161 and the second movable frame 162 can move towards or away from each other. This design allows for multi-directional control of the second housing 120, adapting to different operational needs and application scenarios.

[0124] Optionally, when the driving end of the driving member 150 drives the rotating end of the first movable frame 161 and the rotating end of the second movable frame 162, the moving ends of the first movable frame 161 and the second movable frame 162 gradually move, providing a pushing force to the second housing 120 away from the first housing 110, causing the second housing 120 to move away from the first housing 110. Simultaneously, the moving ends of the first movable frame 161 and the second movable frame 162 move towards each other, at which point the flexible display screen 220 is in a stretched state.

[0125] Optionally, when the driving end of the driving member 150 drives the rotating ends of the first movable frame 161 and the second movable frame 162, the moving ends of the first movable frame 161 and the second movable frame 162 gradually move, providing a pushing force to the second housing 120 to move closer to the first housing 110, causing the second housing 120 to move closer to the first housing 110. Simultaneously, the moving ends of the first movable frame 161 and the second movable frame 162 move in opposite directions, at which point the flexible display screen 220 is in a retracted state.

[0126] Optionally, in order to match the movement trajectory of the first support member 160, the housing assembly 100 further includes a second support member, the structure of which is the same as that of the first support member 160.

[0127] Optionally, the working trajectory of the second support member moves under the drive of the first support member 160.

[0128] The housing assembly provided in this application includes a first housing, a second housing, a transmission assembly, and a support assembly. When the first housing and the second housing slide relative to each other, the transmission assembly drives the flexible display screen to stretch or retract. The support assembly includes a support member disposed on the flexible display screen. The support member has an arc-shaped support portion. The second housing is provided with a sliding groove. The arc-shaped support portion is configured to slide within the sliding groove when the flexible display screen moves.

[0129] The design of the transmission components allows the flexible display screen to smoothly extend and retract when the first and second housings slide relative to each other. The structure occupies little space, and its principle is simple, reliable, and practical, making it less prone to creases on the flexible display screen. The design of the support components, in which the sliding groove and the arc-shaped support part cooperate to ensure a smooth transition of the flexible display screen during movement, improves the smoothness of movement, reduces the risk of jamming or blockage, and thus helps to improve the user experience of the smart terminal.

The structure occupies little space, and the structural principle is simple, reliable and practical. Creases are not easily formed on the flexible display screen. The design of the support component, in which the sliding groove and the arc-shaped support part cooperate to ensure the smooth transition of the flexible display screen during movement, improves the smoothness of movement, reduces the risk of jamming or blockage, and thus helps to improve the user's experience of using the smart terminal.

[0136] Optionally, the following description will use a smart terminal as an example to illustrate the smart terminal in this application. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0137] Figure 14 This is a schematic diagram of the hardware structure of a smart terminal implementing various embodiments of this application. Please refer to [link / reference]. Figure 14 The smart terminal 200 may include: an RF (Radio Frequency) unit 201, a WiFi module 202, an audio output unit 203, an A / V (Audio / Video) input unit 204, a sensor 205, a display unit 206, a user input unit 207, an interface unit 208, a memory 209, a processor 210, and a power supply 211, etc. Those skilled in the art will understand that... Figure 14 The smart terminal structure shown does not constitute a limitation on the smart terminal. A smart terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0138] The following is combined with Figure 14 A detailed introduction to each component of the smart terminal:

[0139] The radio frequency (RF) unit 201 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 210; additionally, it transmits uplink data to the base station. Typically, the RF unit 201 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer.

[0140] WiFi is a short-range wireless transmission technology. Smart terminals, through the WiFi module 202, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 14 The WiFi module 202 is shown, but it is understood that it is not a necessary component of a smart terminal and can be omitted as needed without changing the essence of the utility model.

[0141] The audio output unit 203 can convert audio data received by the radio frequency unit 201 or the WiFi module 202, or stored in the memory 209, into audio signals and output them as sound when the smart terminal 200 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 203 can also provide audio output related to specific functions performed by the smart terminal 200 (e.g., call signal receiving sound, message receiving sound, etc.).

[0142] The A / V input unit 204 is used to receive audio or video signals. The A / V input unit 204 may include a graphics processing unit (GPU) 2041 and a microphone 2042. The GPU 2041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 206. The image frames processed by the GPU 2041 can be stored in the memory 209 (or other storage media) or transmitted via the radio frequency unit 201 or the WiFi module 202. The microphone 2042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 201 in telephone call mode. The microphone 2042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0143] The smart terminal 200 also includes at least one sensor 205, such as a light sensor, a motion sensor, and other sensors.

Optionally, the ambient light sensor can adjust the brightness of the display panel 2061 according to the ambient light level, and the proximity sensor can turn off the display panel 2061 and / or backlight when the smart terminal 200 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that can also be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0145] User input unit 207 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the smart terminal. Optionally, user input unit 207 may include touch panel 2071 and other input devices 2072. Touch panel 2071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 2071), and drive corresponding connection devices according to a pre-set program. Touch panel 2071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 210, and can receive and execute commands sent by processor 210. In addition, touch panel 2071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 2071, the user input unit 207 may also include other input devices 2072. Optionally, other input devices 2072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0146] Optionally, the touch panel 2071 may cover the display panel 2061. When the touch panel 2071 detects a touch operation on or near it, it transmits the information to the processor 210 to determine the type of touch event. Subsequently, the processor 210 provides corresponding visual output on the display panel 2061 based on the type of touch event. Although in Figure 14 In this embodiment, the touch panel 2071 and the display panel 2061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 2071 and the display panel 2061 can be integrated to realize the input and output functions of the smart terminal. The specific implementation is not limited here.

[0147] Interface unit 208 serves as an interface through which at least one external device can connect to smart terminal 200. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 208 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within smart terminal 200, or it may be used to transmit data between smart terminal 200 and the external device.

[0148] The memory 209 can be used to store software programs and various data. The memory 209 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 209 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0149] Processor 210 is the control center of the smart terminal. It connects various parts of the smart terminal via various interfaces and lines. By running or executing software programs and / or modules stored in memory 209, and by calling data stored in memory 209, it performs various functions and processes data of the smart terminal, thereby providing overall monitoring of the smart terminal. Processor 210 may include one or more processing units; preferably, processor 210 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 210.

[0150] The smart terminal 200 may also include a power supply 211 (such as a battery) that supplies power to various components. Preferably, the power supply 211 can be logically connected to the processor 210 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.
