Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a foldable terminal. Background Art

[0002] As flexible folding screen technology matures, folding terminals using flexible screens (such as folding mobile phones, folding tablets, folding computers, folding TVs and other electronic devices) are attracting more and more attention and love. Since the flexible screen can bend and deform under force, the folding terminal includes a flat state and a folded state. The flat state refers to the flexible screen being unfolded as a whole into a flat structure; the folded state refers to the flexible screen being bent into a folded structure. However, after the existing folding terminal switches from the folded state to the flat state, it is easy for the support plate to lift up the flexible screen. If the user presses the flexible screen with his fingers, it is easy to cause damage to the flexible screen, affecting the service life of the flexible screen. In addition, the lifting of the flexible screen also affects the user experience. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a foldable terminal that can extend the service life and user experience of the flexible screen.

[0004] In order to achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect of the present application, a folding terminal is provided, comprising a support device and a flexible screen, the support device comprising a main shaft and a connecting assembly, the connecting assembly comprising a swing arm and a support plate rotatably connected to the swing arm, the swing arm being rotatably connected to the main shaft, the flexible screen being laid on the support plate and the main shaft, the flexible screen being fixedly connected to the support plate, the support plate being located between the swing arm and the flexible screen, the swing arm being provided with a first buckle, the support plate being provided with a second buckle, the second buckle being used to buckle-connect with the first buckle when the folding terminal is in a flattened state.

[0006] The flexible screen can be flattened and folded by the movement of the swing arm relative to the support plate and the main shaft, so that the folding terminal includes a flat state and a folded state. The flat state means that the flexible screen is in a flat structure as a whole. The folded state means that the flexible screen is bent by force to form a folded structure. In the process of switching the folding terminal from the folded state to the flat state, the swing arm moves relative to the main shaft. Due to the constraint of the flexible screen on the support plate, the support plate also rotates relative to the swing arm. When the second buckle is connected to the first buckle, it means that the support plate cannot continue to rotate. The first buckle and the second buckle limit the rotation angle of the support plate relative to the swing arm, thereby reducing the possibility of lifting the flexible screen due to excessive rotation of the support plate relative to the swing arm, improving the flatness of the flexible screen in the flat state, extending the service life of the flexible screen and improving the user experience.

[0007] According to the first aspect, in the first possible implementation method of the present application, the first clip has a first guide slope, and the second clip has a second guide slope.

[0009] According to the first aspect or the first to second possible implementations of the present application, in a third possible implementation of the present application, the first guide slope and the side surface of the first boss together form a first recess. When the folding terminal is in the flattened state, the second clip is accommodated in the first recess and abuts against the inner wall of the first recess, thereby reducing the thickness of the folding terminal.

The first side surface is a slope, that is, the first boss is a slope, which is used to increase the movement space of the support plate. The thickness of the first boss decreases from the side where the second side of the first boss is located toward the other side.

[0011] According to the first aspect or the first to fourth possible implementation methods of the present application, in the fifth possible implementation method of the present application, the support plate includes a plate body and a second boss, the plate body includes a top surface and a bottom surface relatively arranged, the top surface is fixedly connected to the flexible screen, the second boss is protruded on the bottom surface, the second buckle is protruded on the end of the second boss away from the bottom surface, the second guide bevel is provided on the side of the second buckle facing the bottom surface, the second guide bevel, the side surface of the second boss and the bottom surface together form a second recess, when the folding terminal is in the flattened state, the first buckle is accommodated in the second recess and abuts against the inner wall of the second recess, so that the first buckle and the second buckle are both hidden under the plate body.

[0012] According to the first aspect or the first to fifth possible implementations of the present application, in the sixth possible implementation of the present application, a first connecting portion is provided on the side of the main body away from the main axis, the first connecting portion is arranged at intervals from the first boss, a second connecting portion is provided on the support plate, and the first connecting portion and the second connecting portion are connected by a pivot rotation, thereby simplifying the rotational connection structure between the swing arm and the support plate.

[0013] According to the first aspect or the first to sixth possible implementations of the present application, in the seventh possible implementation of the present application, the first connecting part is a convex column, the second connecting part is a groove, the first connecting part is accommodated in the second connecting part and is connected to the side wall of the second connecting part through a pivot rotation, and the convex column is hidden in the groove, which is beneficial to improving the flatness of the flexible screen.

[0025] The embodiments of the present application provide a foldable terminal, wherein the foldable terminal provided can be any terminal such as a wearable device, an AR (augmented reality)\VR (virtual reality) device, a tablet computer, a laptop computer, an UMPC (ultra-mobile personal computer), a netbook, a PDA (personal digital assistant), etc., and the embodiments of the present application do not impose any restrictions on this.

[0026] like Figure 1 As shown, in some embodiments of the present application, the provided foldable terminal may be a mobile phone. The structure of the mobile phone is exemplarily described below using the foldable terminal 100 as an example.

[0027] like Figure 1 As shown, the foldable terminal 100 may specifically include: a processor 101, a radio frequency (RF) circuit 102, a memory 103, a flexible screen 104, a Bluetooth device 105, one or more sensors 106, a Wi-Fi device 107, a positioning device 108, an audio circuit 109, a peripheral interface 110, and a power supply device 111. These components can be connected through one or more communication buses or signal lines ( Figure 1 Those skilled in the art will appreciate that Figure 1 The hardware structure shown in the figure does not constitute a limitation on the folder terminal 100. The folder terminal 100 may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0028] The following combination Figure 1 The various components of the foldable terminal 100 are described in detail:

[0029] The processor 101 is the control center of the foldable terminal 100. It connects various components of the foldable terminal 100 using various interfaces and circuits. It executes various functions of the foldable terminal 100 and processes data by running or executing applications (apps) stored in the memory 103 and calling data stored in the memory 103. In some embodiments, the processor 101 may include one or more processing units.

[0030] The radio frequency circuit 102 can be used to receive and transmit wireless signals during the process of sending and receiving information or making calls. In particular, the radio frequency circuit 102 can receive downlink data from the base station and pass it to the processor 101 for processing. In addition, uplink data can be sent to the base station. Generally, the radio frequency circuit 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 circuit 102 can also communicate with other devices via wireless communication. The wireless communication can use any communication standard or protocol, including but not limited to Global System for Mobile Communications, General Packet Radio Service, Code Division Multiple Access, Wideband Code Division Multiple Access, Long Term Evolution, email, Short Message Service, etc.

[0031] The memory 103 is used to store applications and data. The processor 101 executes various functions and data processing of the foldable terminal 100 by running the applications and data stored in the memory 103. The memory 103 mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system and applications required for at least one function (such as a sound playback function, an image playback function, etc.). The data storage area can store data created when using the foldable terminal 100 (such as audio data, a phone book, etc.). In addition, the memory 103 may include a high-speed random access memory, and may also include a non-volatile memory, such as a disk storage device, a flash memory device or other volatile solid-state storage device. The memory 103 can store various operating systems, such as the iOS operating system developed by Apple and the Android operating system developed by Google.

[0032] The flexible screen 104 is used to provide input and / or output functions for the user. In this embodiment, the flexible screen 104 includes a stacked flexible cover (not shown), a flexible touch screen (not shown), and a flexible display screen (not shown), which are used to display information and provide touch input for the user. It is understood that the flexible screen 104 may also include a flexible touch screen or a flexible display screen; or, the flexible screen 104 may be a flexible screen that integrates touch and display functions, etc., which is not limited here.

[0033] The foldable terminal 100 may further include a Bluetooth device 105 for enabling data exchange between the foldable terminal 100 and other short-range terminals (eg, foldable terminals, smart watches, etc.). The Bluetooth device 105 in the embodiment of the present application may be an integrated circuit or a Bluetooth chip.

[0034] The foldable terminal 100 may also include at least one sensor 106, 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, wherein the ambient light sensor may adjust the brightness of the flexible screen 104 according to the brightness of the ambient light, and the proximity sensor may turn off the power of the flexible screen 104 when the foldable 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 foldable terminal (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 be configured with the foldable terminal 100, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

[0035] The Wi-Fi device 107 is used to provide the foldable terminal 100 with network access that complies with Wi-Fi standard protocols. The foldable terminal 100 can access a Wi-Fi access point through the Wi-Fi device 107, thereby helping the user to send and receive emails, browse the web, and access streaming media, thereby providing the user with wireless broadband Internet access. In some other embodiments, the Wi-Fi device 107 can also serve as a Wi-Fi wireless access point to provide Wi-Fi network access to other terminals.

[0036] The positioning device 108 is used to provide the geographical location for the foldable terminal 100. It is understandable that the positioning device 108 can specifically be a receiver of a positioning system such as the global positioning system (GPS), the Beidou satellite navigation system, or the Russian GLONASS (global navigation satellite system). After receiving the geographical location sent by the above positioning system, the positioning device 108 sends the information to the processor 101 for processing, or sends it to the memory 103 for storage. In some other embodiments, the positioning device 108 can also be a receiver of the assisted global positioning system (AGPS). The AGPS system assists the positioning device 108 in completing ranging and positioning services by acting as an auxiliary server. In this case, the auxiliary positioning server communicates with the positioning device 108 (i.e., GPS receiver) of the terminal, such as the foldable terminal 100, through a wireless communication network to provide positioning assistance. In some other embodiments, the positioning device 108 can also be a positioning technology based on a Wi-Fi access point. Since each Wi-Fi access point has a globally unique MAC address, a terminal can scan and collect broadcast signals from surrounding Wi-Fi access points when Wi-Fi is turned on, thereby obtaining the MAC addresses broadcast by the Wi-Fi access points. The terminal then sends this data (e.g., MAC address) identifying the Wi-Fi access point to a location server via a wireless communication network. The location server retrieves the geographic location of each Wi-Fi access point and, based on the strength of the Wi-Fi broadcast signal, calculates the terminal's geographic location and sends it to the terminal's positioning device 108.

[0037] The audio circuit 109, speaker 113, and microphone 114 provide an audio interface between the user and the foldable terminal 100. The audio circuit 109 converts received audio data into electrical signals and transmits them to the speaker 113, which then converts the signals into sound signals for output. Meanwhile, the microphone 114 converts the collected sound signals into electrical signals, which are then received by the audio circuit 109 and converted into audio data. The audio data is then output to the RF circuit 102 for transmission to, for example, another foldable terminal, or to the memory 103 for further processing.

[0038] The peripheral interface 110 is used to provide various interfaces for external input / output devices (e.g., a keyboard, mouse, external display, external memory, and a subscriber identification module card). For example, the peripheral interface 110 can be connected to a mouse via a Universal Serial Bus (USB) interface, or to a subscriber identification module (SIM) card provided by a telecommunications operator via metal contacts on a SIM card slot. The peripheral interface 110 can be used to couple these external input / output peripheral devices to the processor 101 and the memory 103.

[0039] The foldable terminal 100 may also include a power supply device 111 (such as a battery and a power management chip) to supply power to various components. The battery can be logically connected to the processor 101 through the power management chip, so that the power supply device 111 can manage charging, discharging, and power consumption.

[0040] although Figure 1 Not shown, the foldable terminal 100 may further include a camera (front camera and / or rear camera), a flash, a micro-projection device, a near field communication (NFC) device, etc., which will not be described in detail here.

[0041] See also Figure 2 , Figure 2 This is a side view of the connecting assembly when the foldable terminal is in a flattened state. The foldable terminal 100 also includes a support device 200 that supports the flexible screen 104. The support device 200 includes a main shaft 30 and a connecting assembly 50. The connecting assembly 50 includes a swing arm 51 and a support plate 53 rotatably connected to the swing arm 51. The swing arm 51 is rotatably connected to the main shaft 30. The flexible screen 104 is placed on the support plate 53 and the main shaft 30. The flexible screen 104 is fixedly connected to the support plate 53, which is located between the swing arm 51 and the flexible screen 104.

[0042] The flexible screen 104 can be flattened and folded by the movement of the swing arm 51 relative to the support plate 53 and the main shaft 30, so that the foldable terminal 100 has both a flat state and a folded state. The flat state means that the flexible screen 104 is a flat plate. The folded state means that the flexible screen 104 is bent under force and forms a folded structure.

[0043] In this embodiment, the foldable terminal 100 is an inward-folding foldable terminal, with two connecting assemblies 50. The main shaft 30 is located between the swing arms 51 of the two connecting assemblies 50, and the two connecting assemblies 50 are able to rotate relative to each other. When the foldable terminal 100 is in a folded state, the angle between the two support plates 53 is greater than or equal to 0° and less than 180°. When the angle between the two support plates 53 is approximately 0°, the flexible screens 104 on the two support plates 53 are partially stacked and arranged face to face (i.e., the two support plates 53 are closed). When the foldable terminal 100 is in the flattened state, the two support plates 53 are approximately located on the same plane, i.e., the angle between the two support plates 53 is approximately 180°, and the flexible screen 104 is unfolded as a flat plate structure.

[0044] When the foldable terminal 100 is in a folded state, especially when the two support plates 53 are closed, the foldable terminal 100 occupies less space, thereby facilitating storage, carrying, and use of the foldable terminal 100. When the foldable terminal 100 is in a flattened state, the foldable terminal 100 has a larger display area, thereby facilitating user operation and reading of the foldable terminal 100.

[0045] Please refer to Figure 3 , Figure 3 3D is a schematic diagram of the three-dimensional assembly of the support device of the folding terminal, and the angle between the two support plates 53 is approximately 180 degrees.

[0046] A first buckle 511 is provided on the swing arm 51 , and a second buckle 531 is provided on the support plate 53 . The second buckle 531 is used to be buckled and connected with the first buckle 511 when the folding terminal 100 is in a flat state.

[0047] When the foldable terminal 100 is in the folded state, the first latch 511 is not engaged with the second latch 531. When the foldable terminal 100 is switched from the folded state to the flat state, the swing arm 51 drives the support plate 53 to move relative to the main shaft 30. Due to the constraint of the flexible screen 104 on the support plate 53, the support plate 53 also rotates relative to the swing arm 51. The first latch 511 moves relative to the second latch 531. When the second latch 531 is engaged with the first latch 511, the support plate 53 cannot further rotate relative to the swing arm 51. The engagement of the first latch 511 with the second latch 531 limits the rotation angle of the support plate 53 relative to the swing arm 51, preventing excessive rotation of the support plate 53 relative to the swing arm 51. This reduces the possibility of the support plate 53 tilting and lifting the flexible screen 104, improving the flatness of the flexible screen 104 in the flat state, extending its service life, and enhancing the user experience.

[0048] In this embodiment, the first buckle 511 has a first guide bevel 5111, and the second buckle 531 has a second guide bevel 5131. The first guide bevel 5111 and the second guide bevel 5311 can slide together to guide, thereby improving the smoothness of the movement of the support plate 53 relative to the swing arm 51, thereby improving the user experience.

[0049] More specifically, the swing arm 51 further includes a main body 512 and a first boss 515. The main body 512 is rotatably connected to the main shaft 30, enabling the swing arm 51 to rotate relative to the main shaft 30. A first connecting portion 5121 is provided on a side of the main body 512 away from the main shaft 30 for rotatably connecting to the support plate 53.

[0050] The first boss 515 protrudes from the end surface of the main body 512 and is spaced apart from the first connecting portion 513. The first boss 515 includes a first side 5151, a second side 5153, a third side 5155, and a fourth side 5157, which are sequentially connected. The first side 5151 is an inclined surface, and the second side 5153 and the fourth side 5157 are arranged opposite each other. When the foldable terminal 100 is in the flattened state, the first side 5151 faces the flexible screen 104 and the support plate 53, while the fourth side 5157 faces the main shaft 30. The first side 5151 is an inclined surface, meaning that the first boss 515 is an inclined surface, which increases the movement space of the support plate 53. The thickness of the first boss 515 decreases from the side of the first boss 515 where the second side 5153 is located toward the other side of the first boss 515. It is understood that the fourth side 5157 can be omitted, and the structure of the first boss 515 is not limited.

[0051] The first latch 511 is protruding from the second side surface 5153 near the first side surface 5151. The first guide slope 5111 and the second side surface 5153 of the first boss 515 together form a first recess. When the foldable terminal 100 is in the flattened state, the second latch 513 is received in the first recess and abuts against the inner wall of the first recess, reducing the thickness of the foldable terminal 100.

[0052] The support plate 53 also includes a plate body 532 and a second boss 535. The plate body 532 includes a top surface 5321 and a bottom surface 5323 arranged opposite each other. The top surface 5321 is fixedly connected to the flexible screen 104. The bottom surface 5323 is arranged toward the swing arm 51. A second connecting portion 5325 is provided on the top surface 5321 of the plate body 532. The second connecting portion 5325 is pivotally connected to the first connecting portion 5121. In this embodiment, the first connecting portion 513 is a convex column, and the second connecting portion 5311 is a groove. The first connecting portion 5121 is accommodated in the second connecting portion 5325 and pivotally connected to the side wall of the second connecting portion 5325. It is understood that there is no limitation on the structure of the first connecting portion 5121, and there is no limitation on the structure of the second connecting portion 5325. For example, the first connecting portion 5121 and the second connecting portion 5325 can both be convex columns.

[0053] A second boss 535 protrudes from one end of the bottom surface 5313 of the plate 531. A second latch 531 is located at the end of the second boss 535 away from the plate 531. A first guide slope 5111 is provided on the side of the first latch 511 near the second side surface 5153, and a second guide slope 5311 is provided on the side of the second latch 531 near the plate 531. The first and second guide slopes 5111, 5311, abut against each other when the foldable terminal 100 is in the flattened state. The first and second guide slopes 5111, 5311 are capable of sliding relative to each other, guiding the first and second latches 511, 531, during their connection and disconnection. In this embodiment, both the first and second guide slopes 5111, 5113, are inclined surfaces, designed to reduce lag during the sliding of the first latch 511 relative to the second latch 531, thereby enhancing the smoothness of the sliding of the first latch 511 relative to the second latch 531.

[0054] It is understandable that there is no limitation on the structure of the first buckle 511 or the structure of the second buckle 531 , as long as the first buckle 511 and the second buckle 531 can be buckled together to limit the position when the foldable terminal 100 is in the flat state.

[0055] The main shaft 30 includes a connecting surface 31 and an outer surface 33, wherein the connecting surface 31 is arranged toward the flexible screen 104 and the outer surface 33 is located at the outermost side of the foldable terminal 100. The connecting surface 31 and the flexible screen 104 can be fixed or partially fixed, which is not limited here.

[0056] See also Figure 3 and Figure 4The edge of the connecting surface 31 is provided with a limiting groove 311, which is used to limit the support plate 53 when the foldable terminal 100 is in the flattened state. A groove 5327 is provided on the edge of the plate body 532 on one side near the main shaft 30, extending through the top surface 5321 and the bottom surface 5323 to form an overlapping portion 537. The overlapping portion 537 is intended to be received in the limiting groove 311 of the main shaft 30 and abut against the sidewall of the limiting groove 311 when the foldable terminal 100 is in the flattened state. When the foldable terminal 100 switches from the folded state to the flattened state, the overlapping portion 537 can overlap the limiting groove 311 of the main shaft 30, that is, through the support of the main shaft 30, effectively preventing the support plate 53 and the flexible screen 104 from sinking, thereby protecting the flexible screen 104 and improving the flatness of the flexible screen 104 in the flattened state. It can be understood that the structure of the overlapping portion 537 is not limited, and it can overlap the main shaft 30.
