Description

Technical Field

[0001] This application relates to the field of smart terminals, specifically to a side button component and a smart terminal having the aforementioned side button component. Background Technology

[0002] Side buttons are an important component of mobile phones, serving key functions such as volume control and power on / off. With technological advancements, FPC (Flexible Printed Circuit) technology has been increasingly applied to the manufacturing of side buttons, resulting in more compact and durable structures.

[0003] However, during the conception and implementation of this application, the inventors discovered shortcomings in the existing technology. In some solutions, the side button is assembled into the middle frame from the outside, and a fixed structure is formed by the engagement of the pins at both ends of the side button with the hooks of the side button FPC bracket. In this structure, the positioning of the side button FPC has a large tolerance in terms of shape, which can easily cause eccentricity when mating with the side button, resulting in poor tactile feedback. Furthermore, the side button FPC bracket used to fix the hooks at both ends of the side button is not thick enough, which can easily cause the side button to fall off or wobble and tilt. In some solutions, the side button itself is fixed to the middle frame by its own TPEE clips. This design is prone to deformation during assembly due to the corrosion resistance and insufficient hardness of the TPEE soft rubber material of the side button, which can lead to the side button falling off after the assembly process.

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

[0038] The following description will use a mobile terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0039] Please see Figure 1This is a schematic diagram of the hardware structure of a mobile terminal implementing various embodiments of this application. The mobile 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, etc. Those skilled in the art will understand that... Figure 1 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0040] The following is combined Figure 1 A detailed introduction to each component of the mobile terminal:

[0041] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station. Typically, 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, and a duplexer. Furthermore, the radio frequency unit 101 can also communicate wirelessly with networks and other devices.

[0042] WiFi is a short-range wireless transmission technology. Mobile terminals, through the WiFi module 102, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0043] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0044] 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 of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0045] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and 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 display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0046] 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.

[0047] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0048] Optionally, 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 touch event. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize 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 realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0049] Interface unit 108 serves as an interface through which at least one external device can connect to 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, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 100, or it may be used to transmit data between mobile terminal 100 and the external device.

[0050] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 109 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.

[0051] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0052] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0053] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0054] Based on the hardware structure of the mobile terminal described above, embodiments of this application are proposed.

[0055] like Figures 2 to 7 As shown, one embodiment of this application provides a side button assembly 1, including a side button body 10, a side button bracket 11, and a side button circuit board 12. The side button body 10 is movably mounted on the mid-frame 2 of a smart terminal, the side button bracket 1 is fixed inside the mid-frame 2, and the side button circuit board 12 generates an electronic signal in response to the pressure generated by the side button body 10. The side button bracket 11 is disposed opposite to the side button body 10, and the side button circuit board 12 is disposed between the side button body 10 and the side button bracket 11 and fixed on the side button bracket 11.

[0056] like Figures 3 to 5 As shown, the side key body 10 is an elongated elliptical plate, including a body block 100 and multiple limiting blocks 101. The body block 100 is movably fitted onto the middle frame 2, and the limiting blocks 101 protrude from the outside of the body block 100. The limiting blocks 101 are used to block the middle frame 2 when the body block 100 moves completely or partially outward to prevent the side key body 10 from falling off the middle frame 2. Multiple limiting blocks 101 are evenly arranged on opposite sides of the body block 100, preferably six in number. Optionally, the thickness of the limiting blocks 101 located at both ends of the side key body 10 is greater than the thickness of the limiting block in the middle of the side key body 10, and the thickness of the body block 100 is greater than the thickness of the limiting blocks 101.

[0057] Optionally, the thickness of the limiting block 101 is at least 0.45 mm, and its engagement amount is at least 0.3 mm. The engagement amount refers to the overlap length between the limiting block 101 and the middle frame 2 on both sides of the body block 100, that is, the length from the connection end of the body block 100 and the limiting block 101 to the other end of the limiting frame 101. Optionally, the side key body 10 is preferably made of PC material, which has higher strength and hardness than traditional TPEE material, thus improving the strength and stability of the limiting block 101. Furthermore, the multiple limiting blocks 101 extending from the body block 100 increase the stability of the side key body 10 and effectively prevent the side key from falling off the middle frame 2.

[0058] Optionally, the side button body 10 further includes a buffer 102, which is disposed on the side of the body block 100 facing the side button circuit board 12, for buffering the pressure applied by the body block 100 to the side button circuit board 12 when pressed and protecting the signal converter of the side button circuit board 12. Optionally, the buffer 102 is preferably made of TPU and / or TPE material.

[0059] like Figure 2 and Figure 6 As shown, the side button bracket 11 includes a first connecting plate 110 and a second connecting plate 111. Both the first connecting plate 110 and the second connecting plate 111 are straight strips and are respectively arranged in two mutually perpendicular planes. One side of the first connecting plate 110 is connected to one side of the second connecting plate 111. Optionally, the end of the second connecting plate 111 facing the side button circuit board 12 extends to the inner side of the middle frame 2. The first connecting plate 110 is used to connect with the side button circuit board 12, and the second connecting plate 111 is used to connect with the middle frame 2.

[0060] Optionally, the side button bracket 11 further includes a connecting post 112 and an adhesive layer 113. The connecting post 112 is a straight strip corresponding to the first connecting plate 110. One side of the connecting post 112 is connected to the side button circuit board 12, and the other end is fixedly connected to the first connecting plate 110, for fixing the side button circuit board 12 to the first connecting plate 110. The adhesive layer 113 is disposed between the connecting post 112 and the first connecting plate 110, for connecting the connecting post 112 to the first connecting plate 110. Therefore, the side button circuit board 12 is connected to the side button bracket 11 through the connecting post 112 and the adhesive layer 113, forming a single unit. The side button circuit board 12 is fixedly connected to the side button bracket 11, and the second connecting plate 111 of the side button bracket 11 is fixedly connected to the middle frame 2, that is, the side button circuit board 12 is connected to the middle frame 2 through the side button bracket 11. This design optimizes the positioning accuracy of the side button circuit board 12 and can reduce the influence of the positioning of the side button circuit board 12 on the tolerance.

[0061] This application provides a side key assembly, including a side key body 10, a side key bracket 11, and a side key circuit board 12. The side key body 10 includes a body block 100 and limiting blocks 101. The side key body 10 is made of PC material, which increases the strength of the limiting blocks 101. Multiple limiting blocks 101 are disposed on opposite sides of the body block 100. The multiple high-strength limiting blocks 101 further prevent the side key body 10 from falling off the middle frame 2, improving the stability of the side key body 10. Optionally, the side key bracket 11 includes a connecting post 112 and an adhesive backing layer 113. The side key circuit board 12 is connected to the side key bracket 11 through the connecting post 112 and the adhesive backing layer 113. The other side of the side key bracket 11 is connected to the middle frame 2. That is, the side key circuit board 12 is connected to the middle frame 2 through the side key bracket 11, which optimizes the positioning accuracy of the side key circuit board and reduces the impact of the positioning of the side key circuit board 12 on the tolerance.

[0062] like Figure 7 As shown, an embodiment of this application also provides a smart terminal, including the side button assembly 1, the middle frame 2, and the motherboard as described above; the side button body 10 of the side button assembly 1 is movably fitted onto the middle frame 2 on both sides of the side button body 10, the side button bracket 11 is fixedly connected to the middle frame 2 inside the side button bracket 11, and the side button circuit board 12 is electrically connected to the motherboard of the smart terminal. When the side button body 10 is pressed, the buffer 102 of the side button body 10 abuts against the signal converter of the side button circuit board 12, the signal converter responds and transmits the generated electronic signal to the motherboard, and the motherboard controls the smart terminal to respond.

[0063] Optionally, the middle frame 2 has a mounting groove 20 for accommodating the side key circuit board 12 and the side key bracket 11. The depth of the mounting groove 20 is greater than or equal to the thickness of the side key body 10, which facilitates the installation of the side key body 10 from the inside to the outside of the mounting groove 20. The middle frame 2 also includes a positioning post 21, which is located on the back of the side key bracket 11 and is used to fix the side key bracket 11 to the middle frame 2. The second connecting plate 111 of the side key bracket 11 is fixedly connected to the middle frame 2 through the positioning post 21. The side key bracket 11 is positioned by the positioning post 21, and the side key circuit board 12 is integrated with the side key bracket 11. That is, the side key circuit board 12 is positioned on the middle frame 2 by the side key bracket 11 and the positioning post 21. This positioning method can optimize the positioning accuracy of the side key circuit board 12, increase the stability of the side key circuit board 12, and reduce the fit tolerance between the side key circuit board 12 and the side key body 10, preventing the problem of weak tactile feedback due to eccentricity and improving the user experience.

[0064] Optionally, the side key bracket 11 is positioned by the positioning post 21 and then fixedly connected to the middle frame 2 by a fastener. However, there is a gap between the side key bracket 11 and the middle frame 2, which can be sealed with foam. The fastener is preferably a screw. In a further embodiment, the design can be optimized to a fixing and sealing method of snap-fit ​​fixing + foam sealing or foam adhesive fixing + sealing.

[0065] Optionally, the assembly method of the side key assembly 1 and the middle frame 2 is as follows: First, place the side bracket body 10 into the mounting groove 20, and push the side key body 10 from the inside out until the limiting block 101 of the side key body 10 abuts against the middle frame 2 outside the mounting groove 20, thereby limiting the side key body 10. Second, fix the side key circuit board 12 to the side key bracket 11 through the connecting post 112 and the adhesive layer 113, and then install the side key bracket 11 on the middle frame 2 inside the mounting groove 20 through the positioning post 21 and the fastener, thereby achieving precise positioning of the side key circuit board 12. Finally, fill the space between the side key bracket 11 and the inner middle frame 2 with foam for sealing.

[0066] In summary, this application also provides a smart terminal, including the aforementioned side button assembly 1 and a mid-frame 2. The mid-frame 2 includes a mounting groove 20 and a positioning post 21. The depth of the mounting groove 20 is greater than or equal to the thickness of the side button body 10, which facilitates the side button body 10 of the side button assembly 1 to be fitted into the mid-frame 2 from the inside to the outside of the mounting groove 20. The side button circuit board 12 is integrated with the side button bracket 11, and the side button bracket 11 is fixed to the mid-frame 2 by the positioning post 21. This positioning design optimizes the positioning accuracy of the side button circuit board 12, increases the stability of the side button circuit board 12, and reduces the fit tolerance between the side button circuit board 12 and the side button body 10, preventing the problem of weak tactile feedback due to eccentricity and improving the user experience.
