The mobile terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0033] Combine the following Figure 1 The following is a detailed introduction to the various components of the mobile terminal:

[0034] The radio frequency unit 101 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving the downlink information of the base station, it is sent to the processor 110 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 101 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 101 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution) and TDD-LTE (Time Division Duplexing-Long Term Evolution), etc.

[0035] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0036] The audio output unit 103 can convert the audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0037] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0038] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0039] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0040] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Specifically, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Specifically, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

[0041] Furthermore, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of the touch event. Then, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0042] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. 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, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0043] The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0044] The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the mobile terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0045] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0046] although Figure 1 Not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0047] To facilitate understanding of the embodiments of the present invention, the communication network system on which the mobile terminal of the present invention is based is described below.

[0048] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present invention. The communication network system is an LTE system of universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are sequentially connected for communication.

[0049] Specifically, UE201 may be the above-mentioned mobile terminal 100, which will not be described in detail here.

[0050] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 , etc. Among them, eNodeB 2021 can be connected to other eNodeBs 2022 through a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 can provide UE 201 with access to EPC 203 .

HSS2032 is used to provide some registers to manage functions such as home location register (not shown in the figure), and save some user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, which selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0052] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0053] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present invention is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems, etc., which are not limited here.

[0054] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present invention are proposed.

[0055] First embodiment:

[0056] Please refer to Figure 3-4 , as shown, is a structural schematic diagram and an exploded diagram of a terminal provided in an embodiment of the present invention, wherein the terminal comprises a flexible display module 31, a module volume block 32 and two chain link assemblies 33, wherein the two chain link assemblies 33 are symmetrically arranged on the module volume block 32, and are arranged relative to each other. When the chain link assembly 33 is subjected to a force causing it to bend downward, the chain link assembly 33 is bent downward at a certain angle along the module volume block 32 under the action of the force, and the flexible display module 31 is fixed to the module volume block 32 and the two chain link assemblies 33. In practical applications, the fixation can be achieved by sealing with glue, spot welding, or even by snapping or gluing. The fixing method of the snapping can be achieved by providing a snapping protrusion on the chain link assembly 33, or by separately providing a metal snapping that can be used in conjunction with the chain link assembly 33 to position and fix. Further, as long as the flexible display module 31 can be fixed on its upper surface, the flexible display module 31 will deform with the deformation of the chain link assembly 33.

[0057] In this embodiment, a pair of symmetrically arranged connecting lugs 321 are further arranged on the module volume block 32, and the connecting lugs 321 are specifically arranged on two opposite end faces of the module volume block 32, and the chain link assembly 33 is fixed to the connecting lugs 321 by pins or screws.

[0058] In this embodiment, the module volume block 32 includes an upper cover shell 322 and a lower cover shell 323, and the upper cover shell 322 and the lower cover shell 323 are connected together by snaps or screws, and a pair of connecting lugs 321 are arranged on the upper cover shell 322 and are close to one side of the chain link assembly 33, and the chain link assembly 33 is movably connected to the upper cover shell 322 by pins.

[0059] In this embodiment, a first groove 3221 is further provided on the upper surface of the upper cover shell. The first groove 3221 is formed along the direction of a pair of connecting lugs 321 of the upper cover shell 322, and its size is consistent with the width of the flexible display module 31. Specifically, the first groove 3221 is a long strip groove formed by the inward concave surface of the upper cover shell 322. The direction of the first groove 3221 is along the direction of the line connecting the pair of connecting lugs 321 of the upper cover shell 322 or is consistent with the length direction of the chain link assembly 33.

[0060] In practical applications, the shape of the first groove 3221 can be set to be a long strip (that is, the same as the shape of the long strip flexible display module), but it can also be set to be the same as the shape of the upper surface of the upper cover shell 322, or even directly concave inward according to the shape and size of the upper surface, to obtain a first groove 3221 that occupies the upper surface of the upper cover shell 322, and the corresponding position of the flexible display module 31 corresponding to the first groove 3221 is also set to the same shape, such as Figure 7 As shown, a corresponding special-shaped display module is designed according to the special-shaped shape formed by the chain link assembly 33 and the first groove 3221 on the module volume block 32 .

[0061] In actual applications, the flexible display module 31 is specifically composed of a flexible glass cover plate, a flexible display screen and a support plate, wherein a foam glue is also provided on the support plate, and the foam glue forms a hollow structure on the support plate 1103. In actual applications, the hollow foam glue can be directly used, and then the hollow foam glue is pasted in the middle position of the support plate, the flexible display screen is placed in the hollow structure, and then the flexible glass cover plate is covered on the flexible display screen, and the flexible glass cover plate is pasted with the foam glue, so that the flexible display module 31 is tightened and fixed between the support plate and the flexible glass cover plate.

[0062] In practical applications, in order to further strengthen the flexible display module, the assembly process is specifically as follows: first, OCA glue is set between the flexible glass cover plate and the flexible display screen, and the two are pasted and fixed by the glue, and then the flexible glass cover plate is glued to the supporting substrate by waterproof foam frame glue. Furthermore, in order to strengthen the bonding effect between the back of the flexible display screen and the supporting substrate, a thin layer of OCA glue can be set between the two. The flexible display screen assembled by the above process is not only strong, but also waterproof.

[0063] Furthermore, since this type of wearable flexible terminal has a relatively small and scarce storage space, some electronic devices are difficult to fix and assemble. In order to facilitate the assembly of these devices, in this embodiment, a second groove 3231 is provided on the lower cover shell 323. After the lower cover shell 323 is connected to the upper cover shell 322, a sealed accommodating cavity for placing circuit components is formed between the second groove 3231 and the lower surface of the upper cover shell 322.

[0064] Furthermore, in order to increase the volume of the accommodating cavity, a groove of the same shape as the second groove 3231 is also provided on the lower surface of the upper cover shell 322. When the lower cover shell 323 and the upper cover shell 322 are combined, the volume of the accommodating cavity will be further increased, and the accommodating space of the module volume block 32 will be further expanded.

[0065] like Figure 5 As shown, the module volume block 32 also includes a cover assembly 324, the shape and size of the cover assembly 324 match the shape and size of the upper surface of the upper cover shell 322, and during assembly, the cover assembly 324 is adhered to the upper surface of the upper cover shell 322, and the flexible display module 31 is clamped in the first groove 3221. By adding such a cover assembly 324, the degree of fixation of the flexible display module 31 can be further increased, and the flexible display module 31 can be prevented from convexing at the corresponding position of the module volume block 32 when being bent, thereby protecting the flexible display module 31 and improving the positioning reliability of the non-bending area in the flexible display module 31.

[0066] In actual applications, the cover assembly 324 can be specifically set to a touch panel, or a combined cover with a touch function. When the flexible terminal realizes split-screen display, the user can realize the artificial control of the local display area through the combined cover set in this area, and the setting can also control the display screen of this flexible terminal.

[0067] In this embodiment, the link assembly 33 is composed of at least two links 331, and the links 331 are connected together by a rotational connection and are detachable. In actual applications, the links 331 are connected by pins or screws.

[0068] In this embodiment, the link 331 includes a link body 3311 and a connecting portion 3312 arranged at two symmetrical ends of the link body 3331, wherein the link body 3311 is a link body 3311 with two slightly tilted symmetrical ends, and the connecting portion 3312 is respectively arranged on the two symmetrical ends of the link body 3311, and each link 331 in the link assembly 33 is movably connected through the connecting portion 3312, and a connecting hole 3313 that cooperates with the pin to be fixed is also arranged on the connecting portion 3312, and the connecting hole 3313 can specifically be a circular through hole, and can also be set to a square, a deformable through hole, etc.

[0069] In this embodiment, if Figure 6 As shown, the connection part 3312 specifically includes two parts, namely a limiting connection part 3312a and a matching connection part 3312b. The design shapes and sizes of the limiting connection part 3312a and the matching connection part 3312b are mutually matching structures. If one is set to a concave shape, the other is set to a convex shape.

[0070] In practical applications, the limiting connection portion 3312a and the matching connection portion 3312b are respectively arranged on two symmetrical ends of the connection portion 3312, wherein the limiting connection portion 3312a is arranged on one side of the end of the connection portion 3312 close to the outer surface, and is formed concavely based on the outer surface, and a V-shaped notch 3312c is provided on the end;

[0071] The mating connection portion 3312b is disposed on a side of the connection portion 3312 away from the limiting connection portion 3312a and close to the inner surface, and is formed to be concave inward based on the inner surface, and a V-shaped protrusion 3312d is provided on the end.

[0072] Specific Figure 6 Taking the direction in the figure as an example, the chain link 331 in the figure includes a chain link body 3311 and a connecting portion 3312 arranged at two symmetrical ends of the chain link body 3311, and the limiting connecting portion 3312a in the connecting portion 3312 is arranged on the left end of the connecting portion 3312, and the left end position of the outer surface of the connecting portion 3312 is recessed toward the inner surface, thereby forming a step-like structure at the left position, and a V-shaped notch 3312c is also arranged at the left edge position of the structure, thereby forming a limiting connecting portion 3312a;

[0073] The mating connection portion 3312b is arranged on the right end portion of the connection portion 3312, and is recessed toward the outer surface at the right end position of the inner surface of the connection portion 3312, thereby forming a step-like structure at the right position, and a V-shaped protrusion 3312d mating with the V-shaped notch 3312c is formed at the left edge position of the structure. In actual application, the size of the V-shaped protrusion 3312d is smaller than the size of the V-shaped notch 3312c, thereby forming a mating connection portion 3312b.

[0074] In other embodiments of the present invention, in addition to directly making the flexible display module 31 into a special-shaped screen having the same shape as the watch band composed of the link assembly 33 and the module volume block 32, a glass cover plate 34 for protecting the flexible display module 31 may be provided above the flexible display module 31, such as Figure 8 As shown, the shape of the glass cover 34 is specifically the same as the shape of a watch strap composed of the link assembly 33 and the module volume block 32, and is adhered to the surface of the link assembly 33 and the module volume block 32 by double-sided tape, thereby fixing the flexible display module 31 on the surface of the link assembly 33 and the module volume block 32.

[0075] In actual applications, the glass cover plate 34 can also be set as a touch panel by expanding the function, that is, the touch panel is used instead of the glass cover plate. This not only can achieve the functions of fixing and protecting, but also can increase the touch operation function of the flexible terminal. When the user slides on the flexible display module 31 of the terminal, a certain isolation effect can be achieved through the touch panel (or glass cover plate) set on the flexible display module 31, thereby avoiding the situation where the user directly touches the flexible display module 31 and causes scratches to the flexible display module 31.

[0076] In this embodiment, if the flexible display module 31 or the glass cover plate 34 is fixed only by double-sided tape, its fixing ability is still relatively small, because the elastic restoring force at both ends of the chain link assembly 33 is the largest after bending, which can easily cause the adhesion of the glue pasted on the flexible display module 31 or the glass cover plate 34 to fail. In order to further achieve the fixing effect, at least one fixed chain link 35 with a clamping cavity is also provided on the ends of the two chain link assemblies 33. When the flexible display module 31 is installed on the upper surface of the chain link assembly 33, the two ends of the flexible display module 31 extend into the clamping cavity respectively, and the elastic restoring force at both ends of the chain link assembly 33 can be offset by the cooperation between the flexible display module 31 and the clamping cavity.

[0077] In actual applications, the fixed link 35 can be specifically processed through the link 331, that is, a limit plate 351 is added to the upper surface of the link 331, and the limit plate 351 has a certain distance from the upper surface of the link 331, and the limit plate 351 also extends along the side of the link 331 to the lower surface to form a clamping cavity. In addition to accommodating the extended part structure of the flexible display module 31, the clamping cavity can also accommodate some other electronic components of the terminal, such as an earpiece, a vibration motor, a sensor, etc.

[0078] The present invention proposes a terminal, which includes a flexible display module, a module volume block and two chain link assemblies symmetrically connected to the module volume block, the chain link assembly includes at least two chain links connected in sequence by a rotational connection, the flexible display module is arranged on the upper surface of the module volume block and the chain link assembly, and is fixedly and detachably connected to each chain link on the chain link assembly. Since the flexible terminal provided by the present invention realizes the random change of the overall shape of the terminal through the mutual rotational connection of multiple chain links, the arbitrary bending and folding of the terminal is realized, and at the same time, the rotation amplitude between each chain link is limited by the connecting part on the chain link, so that the deformation degree is small and controllable, avoiding damage to the screen assembly due to excessive bending, greatly improving the user experience, and the structure is simple, easy to produce and process, so that the cost of the produced equipment is low.
