Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] With the development of technology and the continuous progress of the semiconductor industry, the pace of iteration and upgrading of electronic devices such as mobile phones is constantly increasing. Electronic devices typically have side buttons such as a power button, volume up button, and volume down button, which mainly handle functions such as powering on / off, screen on / off, volume adjustment, combined screenshots, combined forced shutdown and restart, and quick launch.

[0003] In related technologies, most side buttons on electronic devices are physical buttons that function by pressing a dome switch. A very small number of electronic devices use pressure-sensitive or pressure-sensitive plus touch buttons that function by pressing and sliding.

[0004] However, physical buttons significantly impact the overall aesthetics of mobile phones, while pressure-sensitive or pressure-sensitive-plus-touch side buttons suffer from drawbacks such as unresponsiveness and accidental triggering in practical applications. In other words, in current electronic devices, it's difficult to balance aesthetics, responsiveness, and accidental touch prevention for buttons, greatly diminishing the user experience. Summary of the Invention

[0005] This application aims to provide an electronic device that at least solves the problem in the related art that it is difficult for the buttons of electronic devices to simultaneously achieve aesthetics, sensitivity, and the function of preventing accidental touches.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an electronic device, which includes: a frame and a button module;

[0008] The frame includes a frame body and side frames, and the side frames and the frame body enclose a cavity.

[0009] The side frame has a groove on the side opposite to the cavity, and the button module is connected to the groove to form a pressing area, which is used to receive the user's pressing operation.

[0010] The button module includes a target sensor and an infrared sensor. The target sensor and the infrared sensor are spaced apart and electrically connected. The target sensor is used to obtain the pressing pressure of the pressing operation, and the infrared sensor is used to obtain the target distance between the user's finger and the pressing area, as well as liveness information.

[0011] Specifically, when the pressing pressure or the target distance meets a first preset condition, and the living information meets a second preset condition, the button function of the button module is triggered.

[0012] Compared with the prior art, the electronic device provided in this application has at least the following advantages:

[0013] In the embodiments of this application, user pressing operations can be obtained by forming a pressing area on the side frame, thereby triggering the button function. This avoids the need for physical buttons on the side frame, improving the overall aesthetics of the electronic device. Simultaneously, by combining pressure sensing from a target sensor or distance sensing from an infrared sensor, the button function of the button module is only triggered when the pressing pressure or target distance meets a first preset condition and the liveness information meets a second preset condition. This not only improves the sensitivity of the button module but also enhances its ability to prevent accidental touches. In other words, in the electronic device described in this application embodiment, the button module can balance aesthetics, sensitivity, and accidental touch prevention, greatly improving the user experience.

[0028] The following description, in conjunction with the accompanying drawings, details an electronic device provided in an embodiment of this application.

[0029] like Figures 1 to 6 As shown, an electronic device according to some embodiments of this application includes: a frame 10 and a button module 20; the frame 10 includes a frame body 101 and a side frame 102, the side frame 102 and the frame body 101 enclosing a cavity; a groove 1021 is provided on the side of the side frame 102 away from the cavity, the button module 20 is connected in the groove 1021 to form a pressing area, the pressing area being used to receive the user's pressing operation; the button module 20 includes a target sensor 201 and an infrared sensor 202, the target sensor 201 and the infrared sensor 202 are spaced apart, and the target sensor 201 and the infrared sensor 202 are electrically connected, the target sensor 201 is used to obtain the pressing pressure of the pressing operation, and the infrared sensor 202 is used to obtain the target distance between the user's finger and the pressing area and the liveness information; wherein, when the pressing pressure or the target distance meets a first preset condition, and the liveness information meets a second preset condition, the button function of the button module 20 is triggered.

[0030] In the embodiments of this application, user pressing operations can be obtained by forming a pressing area on the side frame, thereby triggering the button function. This avoids the need for physical buttons on the side frame, improving the overall aesthetics of the electronic device. Simultaneously, by combining pressure sensing from a target sensor or distance sensing from an infrared sensor, the button function of the button module is only triggered when the pressing pressure or target distance meets a first preset condition and the liveness information meets a second preset condition. This not only improves the sensitivity of the button module but also enhances its ability to prevent accidental touches. In other words, in the electronic device described in this application embodiment, the button module can balance aesthetics, sensitivity, and accidental touch prevention, greatly improving the user experience.

[0031] Specifically, such as Figure 2 and Figure 3As shown, the electronic device may include a frame 10, which includes a frame body 101 and a side frame 102. The side frame 102 is connected to the frame body 101, and the side frame 102 and the frame body 101 enclose a cavity. The cavity can be used to install other components of the electronic device, such as a motherboard, screen, receiver, battery, etc. A groove 1021 is provided on the side of the side frame 102 opposite to the cavity. A button module 20 is provided in the groove 1021 of the side frame 102. The button module 20 is connected to the groove 1021, and a pressing area is formed on the surface of the button module 20 for receiving user pressing operations. In this way, by setting the button assembly 20 in the groove 1021, physical buttons can be eliminated, improving the aesthetics of the electronic device, and also reducing the problems of structural complexity and difficulty in waterproofing caused by adding physical buttons.

[0032] In this embodiment, the button module 20 includes a target sensor 201 and an infrared sensor 202. The target sensor 201 may include a pressure sensor and a touch sensor. The target sensor 201 and the infrared sensor 202 are spaced apart and electrically connected. The target sensor 201 is used to acquire the pressing pressure and touch operation of the pressing operation. The infrared sensor 202 is used to acquire the target distance between the user's finger and the pressing area, as well as liveness information. When the pressing pressure or the target distance meets a first preset condition, and the liveness information meets a second preset condition, the button function of the button module 20 is triggered.

[0033] The first preset condition is that the pressing pressure reaches a preset first pressure threshold of the target sensor 201, or the distance between the user's finger and the target area of ​​the pressing area reaches a preset first distance threshold. If either of these conditions is met, the button function can be triggered, thus improving the sensitivity of the button module. The second preset condition is infrared radiation within the infrared wavelength range radiated by the human body. That is, when the infrared sensor receives infrared radiation within the infrared wavelength range radiated by the human body, it is determined that the second preset condition is met. Therefore, the button function can be triggered only when the human body touches the pressing area, which can improve the button module's ability to prevent accidental touches. In this way, the button module can obtain the pressing pressure from the target sensor 201 and the target distance from the infrared sensor 202, and determine whether the pressing pressure or the target distance meets a first preset condition. If either the pressing pressure or the target distance meets the first preset condition, the button function of the button module 20 can be triggered. This overcomes the problem of low sensitivity and easy failure of existing touch buttons that only have pressure sensing, thus improving the sensitivity of the button. At the same time, by obtaining the liveness information from the infrared sensor 202, it can determine whether the liveness information meets a second preset condition, thereby increasing the collection and judgment of human liveness information, enhancing the button's ability to prevent accidental triggering, and improving the user experience.

[0034] It is understood that the electronic devices in this application embodiment may include: mobile phones, tablets, computers, game consoles, smartwatches, and other electronic devices with a side frame 102 button structure. Typically, the side frame 102 button structure of an electronic device can be used for power switching or volume adjustment. In this application embodiment, there can be two grooves 1021, each groove 1021 connected to a button module 20, and each button module 20 performs a different button function.

[0035] For each button module 20, the number of target sensors 201 and infrared sensors 202 can be one or more. Multiple target sensors 201 and infrared sensors 202 are spaced apart and electrically connected. The multiple target sensors 201 and infrared sensors 202 simultaneously sense the user's pressing operation, and based on the sensing results, the button function of the button module 20 is triggered. The button function can be a power switch, volume control, or other functions of the electronic device. The specific content of the button function can be set according to actual needs. Furthermore, the specific settings of the button control module can be found in related technologies, and this application embodiment does not limit this.

[0036] Optionally, in this embodiment, both the target sensor 201 and the infrared sensor 202 are further used to acquire the trajectory of the pressing operation. When the trajectory meets a third preset condition and the liveness information meets a second preset condition, the button function of the button module 20 is triggered. Thus, compared to the prior art, the button module provided in this embodiment can also realize the corresponding button function through touch sliding operations, enriching the ways to realize button functions and making button operation more user-friendly.

[0037] Specifically, in this embodiment, the target sensor 201 and the infrared sensor 202 can also be used to sense the movement trajectory of the user's pressing operation in the pressing area. When the trajectory meets the third preset condition and the liveness information meets the second preset condition, the button function of the button module 20 can be realized according to the preset correspondence between the movement trajectory and the button function.

[0038] The third preset pressing condition is that the lengths of both the first movement trajectory acquired by the target sensor 201 and the second movement trajectory acquired by the infrared sensor 202 are greater than a preset length value. In other words, when the length of the movement trajectory of the user's pressing operation is less than the preset length value, the third preset condition is not met, and it is determined to be a touch. When the length of the movement trajectory of the user's pressing operation is greater than the preset length value, the third preset condition is met, and it is determined to be a slide. The preset correspondence between the movement trajectory and the button function is that the direction of the corresponding movement trajectory corresponds to the button function. This preset correspondence can be set by the user according to their needs.

[0039] For example, for the button module 20 responsible for volume adjustment, when the user's pressing operation trajectory meets the third preset condition and the liveness information meets the second preset condition, if the movement trajectory is from top to bottom, the corresponding button function is to decrease the volume; if the movement trajectory is from bottom to top, the corresponding button function is to increase the volume. For the button module 20 responsible for power on / off adjustment, when the user's pressing operation trajectory meets the third preset condition and the liveness information meets the second preset condition, if the movement trajectory is from top to bottom, the corresponding button function is to turn off the screen; if the movement trajectory is from bottom to top, the corresponding button function is to power off. It is understood that the specific correspondence between movement trajectory and button function can be set according to user needs or habits, and is not limited to the above correspondence.

[0040] Optionally, in this embodiment, the button module 20 further includes an infrared light guide post 204. The infrared light guide post 204 is connected to the groove 1021 and includes a first side and a second side. The first side is connected to the target sensing element 201 and the infrared sensor 202, respectively, and the second side is flush with the outer surface of the side frame 102. In this way, the loss of infrared light during transmission can be reduced by the infrared light guide post, and the fact that the second side of the infrared light guide post is flush with the outer surface of the side frame can improve the overall aesthetics of the electronic device.

[0041] Reference Figure 1 , Figure 5 and Figure 6 An infrared light guide post 204 is disposed within the groove 1021. One side of the infrared light guide post 204 is connected to both the target sensing element 201 and the infrared sensor 202, while the other side of the infrared light guide post 204 is flush with the outer surface of the side frame 102 of the electronic device, thus filling the groove 1021 and maintaining consistency with the shape of the side frame 102 of the electronic device. The infrared light guide post 204 is used to guide infrared light and reduce light loss during transmission. This effectively improves the overall aesthetics of the electronic device, enables the hiding of buttons for easier user operation, and facilitates the infrared sensor's emission and reception of infrared light, improving the sensor's working efficiency.

[0042] In actual processing, the infrared light guide column 204 can be installed in the groove 1021 by two-color injection molding or insert injection molding, so that the infrared light guide column 204 and the side frame 102 of the electronic device form a closed and shape-preserving solid, thereby achieving the function of guiding light, facilitating waterproofing, and improving the overall aesthetics of the electronic device.

[0043] In practical applications, the infrared light guide post 204 is made of a polymer that can transmit infrared light, such as PC (polycarbonate) plastic, PMMA (polymethyl methacrylate) plastic, acrylic resin, epoxy resin, etc., without any restrictions.

[0044] Optionally, in this embodiment, the infrared sensor 202 has a transmitter and a sensor on the side away from the cavity. The transmitter emits an infrared signal, and the sensor receives the infrared signal reflected back from the target object by the infrared signal emitted by the transmitter. The infrared light guide post 204 is disposed on the side of the infrared sensor 202 away from the cavity and at least covers the transmitter and the sensor. Thus, the infrared sensor can measure the distance to the target object through the transmitter and sensor, thereby improving the sensitivity of the button module by combining it with the pressure sensing of the target sensor.

[0045] Specifically, in this embodiment, to acquire distance, the infrared sensor 202 can be an infrared ranging sensor. An infrared ranging sensor is a measuring device that uses infrared light as a medium, and it has the advantages of a wide measurement range and short response time. The infrared ranging sensor includes a transmitting end and a sensing end, both of which are located on the side opposite to the cavity. The transmitting end is used to emit infrared signals, and the sensing end is used to receive the infrared signals reflected back from the target object by the infrared signals emitted by the transmitting end.

[0046] In actual use, the transmitting end emits an infrared signal. When the user's finger approaches the pressing area, the infrared signal is reflected by the user's finger and then received by the sensing end, thereby obtaining the target distance between the user's finger and the infrared sensor 202, and then determining whether the target distance meets the first preset condition. If it does, it is determined that the user's finger has pressed the pressing area, thereby triggering the button function of the button module. The infrared light guide post 204 is disposed on the side away from the cavity and at least covers the transmitting end and the sensing end to conduct the infrared signal.

[0047] In practical applications, the transmitting end can be an infrared signal emitting diode, and the sensing end can be an infrared signal receiving diode.

[0048] Optionally, in this embodiment, the target sensor 201 and the infrared sensor 202 are spaced apart. This effectively avoids mutual interference between the target sensor and the infrared sensor, improving the reliability of the button module.

[0049] Specifically, refer to Figure 4 In this embodiment of the application, the target sensing element 201 may include a pressure sensing element 2011 and a touch sensing element 2012. The pressure sensing element 2011, the touch sensing element 2012 and the infrared sensor 202 are arranged at intervals to avoid mutual interference between different electronic components, which would affect the performance of the target sensing element 201 or the infrared sensor 202.

[0050] In this embodiment, a button module 20 may contain multiple target sensors 201 and infrared sensors 202, which are arranged at intervals within the groove 1021. By simultaneously sensing the user's pressing operation through multiple target sensors 201 and infrared sensors 202, and jointly triggering the button function of the button module 20 based on the sensing results of the multiple target sensors 201 and infrared sensors 202, the accuracy of the button function is improved. Of course, the specific number and arrangement of the target sensors 201 and infrared sensors 202 can be set according to actual needs, and this embodiment does not impose any limitations on this.

[0051] In this embodiment, multiple target sensors 201 and multiple infrared sensors 202 can be arranged in an interleaved manner. That is, within the groove 1021, an infrared sensor 202 is interleaved between every two target sensors 201, and adjacent sensors are isolated from each other. In this way, the ability to detect user pressing operations at different positions in the formed pressing area is similar. When the user presses at different positions in the pressing area, the target sensors 201 and infrared sensors 202 at different positions can simultaneously detect the user's pressing operation, thereby triggering the button function of the button module 20, thus avoiding partial pressing failure and improving the accuracy of button function.

[0052] Optionally, in this embodiment, the button module 20 further includes a flexible circuit board 203. The flexible circuit board 203 is disposed within the frame body 101 and partially embedded in the groove 1021. The target sensor 201 and the infrared sensor 202 are electrically connected to the flexible circuit board 203. In this way, the flexible circuit board can transmit the signals from the target sensor and the infrared sensor to the control system of the electronic device, and then analyze and judge the signals. The use of a flexible circuit board has better adaptability and can effectively save space inside the electronic device.

[0053] Specifically, refer to Figure 1 and Figure 4 In this embodiment, the flexible circuit board 203 is disposed within the frame body 101 and partially embedded in the groove 1021. One end of the flexible circuit board 203 embedded in the groove 1021 is electrically connected to the target sensing element 201 and the infrared sensor 202 located within the groove 1021. The other end of the flexible circuit board 203 is connected to the motherboard of the electronic device disposed within the frame body 101. The flexible circuit board 203 is used to transmit the information acquired by the target sensing element 201 and the infrared sensor 202 to the motherboard of the electronic device, process the information through the button control module on the motherboard, and execute the corresponding button functions.

[0054] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate.

[0055] In the embodiments of this application, reference is made to Figure 4 The flexible circuit board 203 has multiple patch portions at one end embedded in the groove 1021. Each patch portion corresponds to a multiple target sensor 201 and a multiple infrared sensor 202, and they are spaced apart. The multiple target sensors 201 and the multiple infrared sensors 202 are connected to the flexible circuit board 203 through the multiple patch portions.

[0056] Specifically, refer to Figure 4 In this embodiment, multiple target sensors 201 and multiple infrared sensors 202 are interspersed and evenly arranged, so that the ability of each position in the pressing area to obtain the user's pressing operation is similar, thereby improving the sensitivity of the pressing operation and avoiding pressing failure caused by uneven distribution of the sensors.

[0057] Optionally, in this embodiment, the button module 20 further includes a bracket 205, which is disposed within the groove 1021. The flexible circuit board 203 is connected to the bracket 205, and the bracket 205 supports the flexible circuit board 203. In this way, the bracket can provide good support for the flexible circuit board and the target sensing element and infrared sensor connected to the flexible circuit board, and fix them in place within the groove.

[0058] Specifically, refer to Figure 4 In this embodiment, since the first end of the flexible circuit board 203 embedded in the groove 1021 is provided with multiple patch portions, in order to provide stable support for the patch portions, the button module 20 also includes a bracket 205. One end of the flexible circuit board 203 embedded in the groove 1021 is connected to the bracket 205 to fix the flexible circuit board 203 to the bracket 205, which can protect the patch portions of the flexible circuit board 203 and is also relatively convenient to install.

[0059] The bracket 205 includes a frame and multiple stops. The frame and the stops together form multiple cavities. The size and position of the cavities correspond to the size and position of multiple patch portions of the flexible circuit board 203. The cavities accommodate the patch portions, and the stops limit and isolate them. This facilitates the connection and connection of the flexible circuit board 203 and the bracket 205 during installation, and also isolates different patch portions, thereby isolating different sensors and preventing interference between them.

[0060] In this embodiment, the flexible circuit board 203 is bonded to the bracket 205. (Refer to...) Figure 4 Double-sided adhesive 206 is included between the flexible circuit board 203 and the bracket 205. The double-sided adhesive 206 is used to bond the patch portion of the flexible circuit board 203 to the receiving cavity of the bracket 205, so that the flexible circuit board 203 is bonded to the bracket 205.

[0061] Understandable, Figure 4 The bonding method using double-sided tape 206 shown is only one of the optional embodiments of this application. This application is not limited to bonding with double-sided tape, but can also use glue or other adhesives.

[0062] Optionally, in this embodiment, the target sensor 201 and the infrared sensor 202 are soldered to the flexible circuit board 203. This serves two purposes: firstly, it fixes the target sensor and the infrared sensor in place, and secondly, it enables electrical connection between the target sensor and the infrared sensor and the flexible circuit board.

[0063] Specifically, in this embodiment, the target sensing element 201 and the infrared sensor 202 are connected to the flexible circuit board 203 by soldering. The target sensing element 201 and the infrared sensor 202 can be surface-mount chips. Multiple target sensing elements 201 and multiple infrared sensors 202 can be fixed to the corresponding surface-mount portions of the flexible circuit board 203 first, and then each pin of the multiple target sensing elements 201 and multiple infrared sensors 202 is soldered to the flexible circuit board 203 to achieve electrical connection with the flexible circuit board 203.

[0064] Optionally, in this embodiment, there can be multiple grooves 1021, which are spaced apart along the side frame 102. The number of button modules 20 corresponds to the number of grooves 1021, with one button module 20 connected to one groove 1021. This allows for setting different button areas for different button functions, and the different button areas are isolated from each other, reducing the likelihood of mutual interference and improving button accuracy.

[0065] In this embodiment, multiple grooves 1021 can be formed on the side frame 102 according to the function of the side buttons of the electronic device. The multiple grooves 1021 are spaced apart. At the same time, multiple button modules 20 are provided, the number of button modules 20 corresponding to the number of grooves 1021, and one button module 20 is connected to one groove 1021. In this way, after the button modules 20 are installed in the grooves 1021, the button areas formed by each button module 20 are isolated from each other, reducing interference between different button areas during button operation. When the user presses a button in the pressing area of ​​one button module 20, it is less likely to accidentally press other pressing areas, thus improving the accuracy of the buttons.

[0066] It is understandable that multiple grooves can be formed on the same side of the side frame 102 or on different sides of the side frame 102, depending on actual needs, and there are no restrictions here.

[0067] Optionally, in this embodiment, the button module 20 is bonded to the groove 1021. Bonding the button module to the groove is convenient during processing and also reduces costs.

[0068] In this embodiment, the button module 20 is connected to the groove 1021 by adhesive bonding. The button module 20 is disposed in the receiving cavity of the groove 1021 and is bonded to the inner wall of the groove 1021. In this way, the button module 20 can be fixedly connected to the groove 1021 to improve the overall connection stability of the electronic device.

[0069] Specifically, the button module 20 can be bonded to the groove 1021 using double-sided tape, glue, or other adhesives. This bonding method has the advantages of low cost and ease of operation.

[0070] In summary, the electronic device provided in this application has at least the following advantages over the prior art:

[0071] In the embodiments of this application, user pressing operations can be obtained by forming a pressing area on the side frame, thereby triggering the button function. This avoids the need for physical buttons on the side frame, improving the overall aesthetics of the electronic device. Simultaneously, by combining pressure sensing from a target sensor or distance sensing from an infrared sensor, the button function of the button module is only triggered when the pressing pressure or target distance meets a first preset condition and the liveness information meets a second preset condition. This not only improves the sensitivity of the button module but also enhances its ability to prevent accidental touches. In other words, in the electronic device described in this application embodiment, the button module can balance aesthetics, sensitivity, and accidental touch prevention, greatly improving the user experience.
