Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a smart terminal back cover and a smart terminal. Background Art

[0002] With the continuous development of electronic technology, mobile terminals such as smartphones and tablets have become common electronic devices for users, adding a lot of fun to people's lives. However, during daily use, mobile terminals inevitably fall or are hit or scratched by other objects, causing damage to the mobile terminals. To protect smart terminals, protective cases are currently used.

[0003] During the process of conceiving and implementing this application, the inventors discovered at least the following problems: When a smart terminal falls to the ground, the protective case is ineffective in absorbing the impact energy and fails to properly protect the smart terminal. When the smart terminal falls onto water, the protective case fails to provide buoyancy, causing the protective case and the smart terminal inside to sink, making it difficult for the user to salvage the device. Furthermore, using a protective case on a smart terminal increases the size of the device, making it uncomfortable for the user to hold.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0038] Figure 1 For a hardware structure diagram of a mobile terminal implementing each embodiment of the present application, please refer to Figure 1, which is a schematic diagram of the hardware structure of a smart terminal for implementing various embodiments of the present application. The smart terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that Figure 1 The structure of the smart terminal shown in the figure does not constitute a limitation on the smart terminal. The smart terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0039] The following combination Figure 1 A detailed introduction to each component of the smart terminal:

[0040] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications may 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), TDD-LTE (Time Division Duplexing- Long Term Evolution) and 5G, etc.

[0041] WiFi is a short-range wireless transmission technology. Smart 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 smart terminal and can be omitted as needed without changing the essence of the utility model.

[0042] The audio output unit 103 can convert 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 smart terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the smart terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0043] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data from still images or videos captured by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in various operating modes, such as phone call mode, recording mode, and voice recognition mode, and process such sound into audio data. In phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0044] The smart terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, or other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the panel 1061 based on the ambient light level, and the proximity sensor can turn off the panel 1061 and / or backlight when the smart terminal 100 is brought to your ear. An accelerometer, a type of motion sensor, can detect acceleration in all directions (typically three axes) and, when stationary, can detect the magnitude and direction of gravity. This can be used for applications that recognize the phone's posture (e.g., switching between landscape and portrait modes, related games, magnetometer posture calibration), vibration recognition-related functions (e.g., pedometers and tapping). Other sensors that may be configured on a phone, such as a fingerprint sensor, pressure sensor, iris sensor, molecular sensor, gyroscope, barometer, hygrometer, thermometer, infrared sensor, etc., are not described here.

[0045] 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 flexible 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.

[0046] The user input unit 107 is used to receive input digital or character information and generate key signal input related to user settings and function control of the smart terminal. Optionally, 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 detect user touch operations on or near it (for example, operations performed on or near the touch panel 1071 using a finger, stylus, or any other suitable object or accessory) and drive corresponding connected devices according to pre-set programs. The touch panel 1071 may include a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects signals generated by the touch operation, transmitting the signals to the touch controller. The touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 110. The touch controller can also receive and execute commands from the processor 110. Furthermore, the touch panel 1071 can be implemented using various types of sensors, including resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0047] Optionally, the touch panel 1071 may cover the flexible 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 touch event. The processor 110 then provides a corresponding visual output on the panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the flexible display panel 1061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the flexible display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0048] The interface unit 108 serves as an interface through which at least one external device can be connected to the smart 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 the external device and transmit the received input to one or more components within the smart terminal 100, or may be used to transmit data between the smart terminal 100 and the external device.

[0049] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as sound playback or image playback); the data storage area may store data generated based on the use of the phone (such as audio data and a phone book). Memory 109 may also include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0050] Processor 110 is the control center of the smart terminal, connecting all components of the smart terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the smart terminal and processes data, thereby providing overall monitoring of the smart terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0051] The smart 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 through a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0052] although Figure 1 Not shown, the smart terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0053] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0054] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present application. 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 connected in sequence.

[0055] Optionally, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0056] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 . Optionally, eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (eg, an X2 interface). eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 may provide UE 201 with access to EPC 203 .

[0057] The EPC 203 may include an MME (Mobility Management Entity) 2031, an HSS (Home Subscriber Server) 2032, other MMEs 2033, an SGW (Serving GateWay) 2034, a PGW (PDN GateWay) 2035, and a PCRF (Policy and Charging Rules Function) 2036. Optionally, the MME 2031 is a control node that processes signaling between the UE 201 and the EPC 203, providing bearer and connection management. The HSS 2032 provides registers for managing functions such as the Home Location Register (not shown) and stores 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 flows and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0058] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem), or other IP services.

[0059] Although the above introduction takes the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., which are not limited here.

[0060] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0061] Figure 3 This is a schematic diagram of the three-dimensional structure of the back cover of the smart terminal of this application. Figure 4 This is a perspective structural diagram of the back cover of the smart terminal of this application. Figure 5 is a schematic cross-sectional view of the rear cover of the smart terminal of the present application along its width direction. Figure 6 This is a cross-sectional structural diagram of the back cover of the smart terminal of this application along its diagonal direction, please refer to Figures 3 to 6The back cover of the smart terminal includes a cover plate 12 and an inflation mechanism 14. The cover plate 12 is provided with at least one airbag 131. The inflation mechanism 14 is connected inside the cover plate 12 and is used to inflate the airbag 131 so that the airbag 131 expands outward from the cover plate 12.

[0062] The back cover of the smart terminal in this application features an inflatable airbag 131. This airbag 131 increases the distance between the smart terminal and the ground, effectively absorbing the potential energy of impact in the event of a fall, and effectively protecting the smart terminal. Furthermore, the inflated airbag 131 provides a certain amount of buoyancy. If the smart terminal falls into water, the airbag 131 ensures that the smart terminal floats on the surface, facilitating emergency salvage and minimizing user losses. Furthermore, there is no need to use a protective case on the smart terminal, making the overall device smaller and more comfortable for the user to hold.

[0063] Optionally, Figure 7 yes Figure 6 The partially enlarged structural diagram of the cover shown in FIG. Figure 8 This is a cross-sectional structural diagram of the airbag of this application in an expanded state, please refer to Figures 6 to 8 At least one inflation channel 302 and at least one sliding channel 303 are provided in the cover plate 12. The inflation channel 302 connects the airbag 131 and the sliding channel 303. The inflation mechanism 14 includes at least one slider 141 and at least one elastic member 142. The slider 141 is installed in the sliding channel 303. The elastic member 142 is connected between the slider 141 and the cover plate 12. The elastic member 142 relies on elastic force to drive the slider 141 to slide toward the inflation channel 302 to compress air into the airbag 131.

[0064] Alternatively, as Figure 7 As shown, a first guide post 1411 is provided at the end of the slider 141, and a second guide post 121 is provided on the cover plate 12 corresponding to the sliding channel 303. One end of the elastic member 142 is sleeved on the first guide post 1411, and the other end of the elastic member 142 is sleeved on the second guide post 121. In this embodiment, the elastic member 142 is, for example, a spring or a spring, but is not limited thereto.

[0065] Alternatively, as Figure 3 and Figure 4 As shown, the inflation mechanism 14 also includes at least one locking switch 143, which is used to lock or unlock the slider 141; when the locking switch 143 locks the slider 141, the elastic member 142 is in a compressed state; when the locking switch 143 unlocks the slider 141, the elastic member 142 drives the slider 141 by relying on elastic force.

[0066] Alternatively, as Figure 3As shown, the inflation mechanism 14 is provided with a connector (not shown) electrically connected to the smart terminal; when the acceleration sensor of the smart terminal detects that it is in a free fall state, the locking switch 143 unlocks the slider 141.

[0067] Alternatively, as Figure 4 As shown, the slider 141 has a locking hole 306 , and the locking switch 143 includes a driving portion 1431 and a locking block 1432 . The driving portion 1431 is used to drive the locking block 1432 into the locking hole 306 to lock the slider 141 and drive the locking block 1432 out of the locking hole 306 to unlock the slider 141 .

[0068] Alternatively, as Figure 6 and Figure 8 As shown, a protrusion 1412 is provided on the slider 141, and at least one wire hole 304 is provided on the cover plate 12. The wire hole 304 passes through the cover plate 12, and the wire hole 304 is arranged along the sliding direction of the slider 141. The protrusion 1412 is arranged in the wire hole 304. Pushing the protrusion 1412 along the length direction of the wire hole 304 can drive the slider 141 to compress the elastic member 142. When the driving portion 1431 drives the block 1432 to retract and move the block 1432 out of the hole 306, the elastic member 142 relies on the elastic force to drive the slider 141 to slide toward the inflation channel 302 to compress the air into the airbag 131. At this time, the airbag 131 expands and bulges; when the protrusion 1412 is pushed in the direction away from the inflation channel 302, the slider 141 moves in the direction away from the inflation channel 302, thereby compressing the elastic member 142 until the slider 141 moves to the hole 306 and is opposite to the block 1432. The driving portion 1431 drives the block 1432 to be inserted into the hole 306, thereby locking the slider 141; therefore, the inflation mechanism 14 can be recycled and has a good cost-effectiveness.

[0069] Optionally, the inflation mechanism 14 further includes at least one sealing ring (not shown). The inner ring of the sealing ring is disposed around the outer wall of the slider 141 and contacts the inner wall of the sliding channel 303. In this embodiment, the sealing ring has a certain degree of elasticity and is capable of sealing the gap between the slider 141 and the sliding channel 303, thereby preventing the airbag 131 from deflation and shrinking.

[0070] Alternatively, as Figure 3 and Figure 6 As shown, the cover 12 includes a base plate 122 and an inner shell 123. The base plate 122 is provided with a mounting groove 305, and the inner shell 123 is mounted in the mounting groove 305. The inflation channel 302 is formed in the base plate 122, and the sliding channel 303 is formed in the inner shell 123. In this embodiment, the locking switch 143 is disposed in the mounting groove 305 and is fixedly connected to the inner shell 123.

[0071] Alternatively, as Figure 6As shown, the inner shell 123 includes a bearing shell 1231 and a cover 1232 . The bearing shell 1231 is provided with at least one guide rail, and a groove is formed along the length direction of the guide rail. The cover 1232 covers the bearing shell 1231 , and the cover 1232 covers the groove to form a sliding channel 303 .

[0072] Alternatively, as Figure 3 and Figure 8 As shown, the cover plate 12 is provided with four airbags 131, which are respectively arranged at the four corners of the cover plate 12. Four inflation channels 302 and four sliding channels 303 are provided in the cover plate 12. The inflation mechanism 14 includes four sliders 141, four elastic members 142, and four locking switches 143. In this embodiment, the four inflation channels 302 and four sliding channels 303 are arranged along the two diagonals of the cover plate 12.

[0073] Optionally, the four locking switches 143 can independently lock or unlock the slider 141, that is, the four locking switches 143 can work independently, can cope with various complex falling environments in life, and have good application prospects.

[0074] Optionally, the carrier shell 1231 includes a middle portion and four guide rails connected to the middle portion, with the four guide rails being arranged along two diagonal lines of the cover plate 12. In this embodiment, the interior of the middle portion defines a cavity 307; when the back cover of the smart terminal falls into water, the cavity 307 can provide a certain amount of buoyancy, allowing the back cover of the smart terminal to sink.

[0075] The slider 141 of the present application can move back and forth in the sliding channel 303. Through the mutual conversion of elastic potential energy, air compression and kinetic energy, the volume of the airbags 131 at the four corners of the back cover of the smart terminal is increased, making the back cover of the smart terminal elastic and better protecting the smart terminal. When the back cover of the smart terminal loaded with the smart terminal falls into the water, the four airbags 131 at the four corners of the cover plate 12 are inflated, and the four airbags 131 provide greater buoyancy, so that the smart terminal can float on the water surface.
