Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0040] (1) Satellite phone or cellular phone;

[0041] (2) A personal communications system (PCS) terminal that can combine cellular radio telephone with data processing, fax and data communication capabilities;

[0045] refer to Figure 1 and Figure 2In some embodiments, the foldable mobile terminal 10 is a smartphone. The foldable mobile terminal 10 includes a flexible display screen 11 and a housing assembly 13. The housing assembly 13 may include a first housing 131, a second housing 133, and a folding assembly 135 connecting the first housing 131 and the second housing 133. One end of the flexible display screen 11 is fixed relative to the position of the first housing 131, and the opposite end of the flexible display screen 11 is fixed relative to the position of the second housing 133. The flexible display screen 11 has bendable characteristics and can be used to display information and provide an interactive interface for the user. The housing assembly 13 can provide support for the flexible display screen 11 and protect it. The first housing 131 and the second housing 133 can be opened and closed via the folding assembly 135, causing the flexible display screen 11 to switch between an open state and a closed state.

[0046] In this embodiment, when the flexible display screen 11 of the foldable mobile terminal 10 is in a closed state, the flexible display screen 11 is hidden between the first housing 131 and the second housing 133, and the foldable mobile terminal 10 can achieve a relatively small external size for easy carrying by the user. When the flexible display screen 11 of the foldable mobile terminal 10 is in an open state, the flexible display screen 11 can be flattened, that is, the displayable area of ​​the flexible display screen 11 is located on the same plane, and the foldable mobile terminal 10 can achieve a relatively large display area to improve the user experience. Furthermore, in some embodiments, the displayable area of ​​the flexible display screen 11 in the open state can be rectangular or rounded rectangular.

[0047] The flexible display screen 11 may include a first fixing part 111, a second fixing part 113, and a bendable part 115 connected between the first fixing part 111 and the second fixing part 113. The first fixing part 111 and the first housing 131 are relatively fixed in position, and the second fixing part 113 and the second housing 133 are relatively fixed in position. During the switching between the open and closed states of the flexible display screen 11, the bendable part 115 undergoes bending deformation. In other words, when the flexible display screen 11 of the foldable mobile terminal 10 switches between the open and closed states, there is no relative movement between the first fixing part 111 and the first housing 131, and no relative movement between the second fixing part 113 and the second housing 133. The bendable part 115 between the first fixing part 111 and the second fixing part 113 can undergo bending deformation to adapt to the shape of the housing assembly 13.

[0048] It is understood that in the embodiments of this application, the relatively fixed positions of the two objects mean that the two objects cannot generate relative movement under normal circumstances or the relative movement between the two objects is negligible. The two objects with relatively fixed positions can be physically directly connected, or they can be indirectly connected through an intermediate structure. Taking the first fixing part 111 and the first housing 131 as an example, the relatively fixed positions of the first fixing part 111 and the first housing 131 can be directly in contact, for example, by using threaded fasteners or clamps to achieve direct fixation of the first fixing part 111 and the first housing 131, or the first fixing part 111 can be indirectly fixed to the first housing 131 through an adhesive layer, an intermediate connecting plate, or other structures. The connection method of the second fixing part 113 and the second housing 133 is similar to the connection method of the first fixing part 111 and the first housing 131, and will not be described again here.

[0049] refer to Figure 3 and Figure 4 The folding assembly 135 includes a base 1351, a support plate 1353, and a baffle 1355. The support plate 1353 and the baffle 1355 are respectively connected to the base 1351, and the position of the support plate 1353 is relatively fixed relative to the position of the base 1351. The baffle 1355 is movably connected to the base 1351. During the process of the shell assembly 13 driving the flexible display screen 11 to switch between an open state and a closed state, the base 1351 can move relative to the first shell 131 and the second shell 133, so that the total length of the side of the shell assembly 13 facing away from the flexible display screen 11 changes, thereby adapting to the radius difference of the flexible display screen 11 during the bending process. For example, in some embodiments, in the open state, the base 1351 is hidden between the first shell 131 and the second shell 133; in the closed state, the base 1351 is exposed to the outside and covers the gap at the connection between the first shell 131 and the second shell 133.

[0050] In some embodiments, the support plate 1353 is generally rectangular thin plate, combined with Figure 5 In the width direction of the support plate 1353, at least one edge of the support plate 1353 is provided with spaced-apart limiting grooves 1353a. The edge of the baffle 1355 is provided with spaced-apart protruding arms 1355a. During the switching between the open and closed states of the flexible display screen 11, the baffle 1355 moves relative to the base 1351 and the support plate 1353. In the open state, the protruding arms 1355a are correspondingly accommodated in the limiting grooves 1353a, so that the support plate 1353 and the baffle 1355 jointly support the bendable portion 115 of the flexible display screen 11, thereby ensuring the flatness of the flexible display screen 11 in the open state.

[0051] refer to Figure 4In some embodiments, two baffles 1355 are provided. When the flexible display screen 11 is in the closed state, the bendable portion 115 is generally bent into a teardrop shape. The side of the bendable portion 115 near the support plate 1353 can be spaced apart from the support plate 1353 to avoid the support plate 1353 squeezing the bendable portion 115 and affecting the service life of the flexible display screen 11. When the flexible display screen 11 is in the closed state, the baffle 1355 on the first housing 131 side can be attached to the flexible display screen 11 on the first housing 131 side and exert appropriate pressure on the flexible display screen 11 on that side to limit and protect the flexible display screen 11 on that side; the baffle 1355 on the second housing 133 side can be attached to the flexible display screen 11 on the second housing 133 side and exert appropriate pressure on the flexible display screen 11 on that side to limit and protect the flexible display screen 11 on that side. The resistance force of the baffle 1355 to the flexible display screen 11 can be achieved by springs, torsion springs or elastic columns, etc. The resistance force of the baffle 1355 to the flexible display screen 11 can also be used to guide the bending deformation of the bendable part 115 of the flexible display screen 11.

[0052] When the flexible display screen 11 is in the open state, one baffle 1355 is disposed on one side of the base 1351 and is used to support the flexible display screen 11 on the side of the first housing 131 in the open state. The other baffle 1355 is disposed on the opposite side of the base 1351 and is used to support the flexible display screen 11 on the side of the second housing 133 in the open state. In this embodiment, both edges of the baffle 1355 in the width direction are provided with limiting grooves 1353a. The baffles 1355 on opposite sides of the base 1351 are provided with spaced protruding arms 1355a. The limiting groove 1353a on any side of the support plate 1353 corresponds one-to-one with the protruding arm 1355a of the baffle 1355 on the same side, and is used to support the bendable part 115 of the flexible display screen 11 in the open state. This application uses the cooperation between the protruding arm 1355a of the baffle 1355 on the second housing 133 side and the support plate 1353 on the same side as an example for explanation. The cooperation between the protruding arm 1355a of the baffle 1355 on the first housing 131 side and the support plate 1353 on the same side is similar, so it will not be described again.

[0053] In other embodiments, a limiting groove 1353a is provided on one side of the support plate 1353, and a protruding arm 1355a is provided on the baffle 1355 on the same side of the support plate 1353. The limiting groove 1353a is not required on the opposite side of the support plate 1353, and the protruding arm 1355a is not required on the baffle 1355 on the opposite side of the support plate 1353.

[0054] In related technologies, when the flexible display screen 11 is in the open state, the support plate 1353 and the baffle 1355 are generally spaced apart in the width direction of the foldable mobile terminal 10. Since the support plate 1353 and the baffle 1355 can move relative to each other, the existence of processing errors of the support plate 1353 and the baffle 1355 as well as assembly errors of related components makes it difficult to ensure that the surface of the support plate 1353 facing the flexible display screen 11 and the surface of the baffle 1355 facing the flexible display screen 11 are flush in the open state. This will cause creases to form on the flexible display screen 11 due to uneven support during the opening and closing process. On the other hand, due to the existence of the gap between the support plate 1353 and the baffle 1355, the gap extends from one end of the foldable mobile terminal 10 to the opposite end of the foldable mobile terminal 10 in the length direction. This structural arrangement results in the flexible display screen 11 covering the gap lacking support. This part of the flexible display screen 11 tends to be concave inward during the opening and closing process, so it is easier to generate creases, which will have an adverse effect on the appearance and use of the foldable mobile terminal 10.

[0055] In this embodiment, the folding assembly 135 includes a base 1351, a support plate 1353, and a baffle 1355. The edge of the support plate 1353 is provided with spaced-apart limiting grooves 1353a, and the edge of the baffle 1355 is provided with spaced-apart protruding arms 1355a. In the open state, the protruding arms 1355a are accommodated in the limiting grooves 1353a one by one, so that the support plate 1353 and the baffle 1355 jointly support the flexible display screen 11. The cooperation between the protruding arms 1355a and the limiting grooves 1353a can effectively support the bending and deforming parts of the flexible display screen 111, and prevent uneven creases from occurring in the bendable part 115 of the flexible display screen 11 due to lack of effective support caused by the gap between the support plate 1353 and the baffle 1355 in the open state.

[0056] In some embodiments, when the flexible display screen 11 is in the open state, the side of the support plate 1353 facing the flexible display screen 11 and the side of the baffle 1355 facing the flexible display screen 11 are flush. That is, when the flexible display screen 11 is in the open state, the surfaces of the support plate 1353 and the baffle 1355 facing the flexible display screen 11 can be coplanar to provide flat support for the bendable portion 115 of the flexible display screen 11. Since the protrusion 1355a on the baffle 1355 extends into the limiting groove 1353a of the support plate 1353, causing the baffle 1355 and the support plate 1353 to cross structurally, there is no longer a continuous straight-line interval between the baffle 1355 and the support plate 1353 extending from one end of the foldable mobile terminal 10 to the opposite end in the length direction of the foldable mobile terminal 10. Therefore, it can effectively support the flexible display screen 11 in the open state and prevent creases from forming in the bendable portion 115.

[0057] In some embodiments, when the flexible display screen 11 is in the open state, there is a gap d between the circumferential edge of the protruding arm 1355a and the groove wall of the limiting groove 1353a. The width of the gap d can be 0.2mm-0.5mm. For example, the width of the gap d can be 0.3mm, 0.4mm, or 0.45mm. The gap d can prevent the baffle 1355 from interfering with the support plate 1353 during its movement relative to the support plate 1353, thereby reducing the assembly accuracy requirements of the baffle 1355 and the support plate 1353 on the base 1351 and improving assembly efficiency.

[0058] Furthermore, in some embodiments, when the flexible display screen 11 is in the open state, the length of the protruding arm 1355a extending into the limiting groove 1353a is not less than half the width of the support plate 1353. In other words, when the flexible display screen 11 is in the open state, in the width direction of the support plate 1353, the length of the protruding arm 1355a of the baffle 1355 extending into the limiting groove 1353a is greater than or equal to half the width of the support plate 1353. This arrangement can utilize the protruding arm 1355a of the baffle 1355 to ensure the support strength of the bendable portion 115 of the flexible display screen 11, thereby preventing the formation of creases. In particular, refer to... Figure 6In this embodiment, when the flexible display screen 11 is in the open state, the side of the baffle 1355 facing the flexible display screen 11 can protrude beyond the side of the support plate 1353 facing the flexible display screen 11. Since the length of the protruding arm 1355a of the baffle 1355 extending into the limiting groove 1353a is greater than or equal to half the width of the support plate 1353, the protruding arm 1355a protruding from the support plate 1353 can provide better support for the bendable portion 115 of the flexible display screen 11, and the upward pushing action of the protruding arm 1355a protruding from the support plate 1353 on the bendable portion 115 can also generate a stretching effect on the bendable portion 115, thereby preventing the formation of creases. By combining the convex arm 1355a of the baffle 1355 on the opposite side of the support plate 1353, the convex arms 1355a on both sides can protrude from the support plate 1353. In the width direction of the foldable mobile terminal 10, the convex arms 1355a of the two baffles 1355 prevent the baffle 1355 and the support plate 1353 from having a continuous straight-line gap extending from one end of the foldable mobile terminal 10 to the opposite end, thereby preventing the formation of creases.

[0059] refer to Figure 5 In some embodiments, the limiting groove 1353a is a rectangular groove, and the shape of the protruding arm 1355a is adapted to the shape of the limiting groove 1353a, that is, the protruding arm 1355a is a rectangular block and there is a gap between the circumference of the protruding arm 1355a and the groove wall of the rectangular groove. The limiting groove 1353a and the protruding arm 1355a with this structure are relatively easy to process.

[0060] refer to Figure 7 , Figure 8 and Figure 9 In other embodiments, the limiting groove 1353a can be a triangular groove, a trapezoidal groove, or at least partially a semi-circular groove, etc., wherein the limiting groove 1353a that is at least partially a semi-circular groove can be... Figure 9 The combination of the semi-circular groove and the rectangular groove shown can be achieved by adapting the shape of the protruding arm 1355a to the shape of the limiting groove 1353a. In this embodiment, to ensure the supporting strength of the protruding arm 1355a for the flexible display screen 11 in the open state, the length of the protruding arm 1355a extending into the limiting groove 1353a can be understood as the distance between the end of the protruding arm 1355a and the same side edge of the support plate 1353, i.e., the opening of the limiting groove 1353a. This length should not be less than half the width of the support plate 1353.

[0061] refer to Figure 10 , Figure 10This is a schematic diagram of the structure of a terminal device 10 provided in an embodiment of this application. The terminal device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless Fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509, among other components. Those skilled in the art will understand that... Figure 10 The structure of the terminal device 10 shown does not constitute a limitation on the terminal device 10. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0062] The radio frequency (RF) circuit 501 can be used to send and receive information, or to receive and send signals during a call. Specifically, it receives downlink information from the base station and hands it over to one or more processors 508 for processing; additionally, it sends uplink data to the base station. Typically, the RF circuit 501 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, the RF circuit 501 can also communicate wirelessly with networks and other devices. This wireless communication can use any communication standard or protocol, including but not limited to GSM, GPRS, CDMA, WCDMA, LTE, email, and SMS.

[0063] Memory 502 can be used to store applications and data. The applications stored in memory 502 contain executable code. Applications can be composed of various functional modules. Processor 508 executes various functional applications and data processing by running the applications stored in memory 502. Memory 502 may primarily include a program storage area and a data storage area. 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 terminal device 10 (such as audio data, phonebook, etc.). Furthermore, memory 502 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. Accordingly, memory 502 may also include a memory controller to provide access to memory 502 for processor 508 and input unit 503.

[0064] Input unit 503 can be used to receive input numbers, character information, or user characteristic information (such as fingerprints), and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control. Specifically, in one embodiment, input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or touchpad, 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 the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch orientation and the signal generated by the touch operation, transmitting 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 the processor 508, and can receive and execute commands from the processor 508.

[0065] Display unit 504 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of terminal device 10. These graphical user interfaces can be composed of graphics, text, icons, video, and any combination thereof. Display unit 504 may include a display panel. Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or similar means. Furthermore, a touch-sensitive surface can cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to processor 508 to determine the type of touch event. Subsequently, processor 508 provides corresponding visual output on the display panel according to the type of touch event. Although in Figure 10 In this context, the touch-sensitive surface and the display panel are two separate components for implementing input and output functions. However, in some embodiments, the touch-sensitive surface and the display panel can be integrated to achieve both input and output functions.

[0066] The terminal device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel according to the ambient light level, and the proximity sensor can turn off the display panel and / or backlight when the terminal device 10 is moved to the ear. As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and 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 may be configured in the terminal device 10, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0067] The audio circuit 506 provides an audio interface between the user and the terminal device 10 via a speaker and a microphone. The audio circuit 506 converts received audio data into electrical signals, transmits them to the speaker, and the speaker outputs them as sound signals. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by the audio circuit 506, converted back into audio data, and processed by the processor 508. The audio data is then transmitted via the radio frequency circuit 501 to, for example, another terminal device 10, or output to the memory 502 for further processing.
