[0002] With the improvement of user demand, the performance and appearance of electronic devices are continuously being optimized. In recent years, the number of physical buttons on electronic devices has become less and less. However, due to functional requirements, the volume up button, volume down button and power button are indispensable. Most existing electronic devices are equipped with three physical buttons: volume up button, volume down button and power on button to realize the functions of volume up and down and power on or screen lighting. However, the three physical buttons of volume up button, volume down button and power on button always have independent convex hulls in appearance, which affects the grip and appearance of electronic devices, and the structural gap between the physical buttons and the surrounding shell is a weak point of ESD (Electro-Static discharge). At the same time, the key signal of the physical button is directly connected to the GPIO (General-purpose input / output) port of the main chip, which increases the risk of system electrostatic failure of electronic devices. Summary of the invention

[0039] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0040] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0041] like Figure 1-6 As shown, the present application provides a key circuit of an electronic device 10 and an electronic device, wherein the electronic device 10 can be a smart phone, a tablet computer, an e-book reader, a wearable device (such as a smart watch), an electronic game console, etc. The embodiments of the present application do not limit the specific type of the electronic device 10.

[0042] like Figure 1 As shown, the switching circuit of the electronic device 10 of the present application includes a first button 100 and a switching circuit 300, wherein the first button 100 is a physical button, the electronic device 10 includes a shell, the first button 100 can be set on the side wall of the shell of the electronic device 10, the switching circuit 300 can be set on a circuit board, and the switching circuit 300 includes a first contact 310, a switch unit, a first control signal terminal 360 and a second control signal terminal 370.

[0043] The first button 100 is connected to the first contact 310. Pressing the first button 100 can realize the control of the first contact 310. The first control signal terminal 360 is used to output the first control signal, and the second control signal terminal 370 is used to output the second control signal. The first contact 310 can be selectively connected to one of the first control signal terminal 360 and the second control signal terminal 370 to trigger the first control signal or the second control signal.

[0044] When the electronic device is in the off or locked state, the switch unit connects the first contact 310 and the second control signal terminal 370, and the first button 100 is used to trigger the second control signal; and when the electronic device is in the bright screen state, the switch unit connects the first contact 310 and the first control signal terminal 360, and the first button 100 is used to trigger the first control signal.

[0045] In the embodiment of the present application, the first button 100 is a volume plus button, the first control signal is a volume plus control signal, and the second control signal is a power-on control signal or a screen-on control signal. When the electronic device 10 is in a power-off or screen-locked state, the volume plus button can be used to control the electronic device 10 to power on or turn on the screen. When the electronic device 10 is in the screen-on state, the volume plus button controls the electronic device 10 to increase the volume.

[0046] Alternatively, in another embodiment of the present application, the first button 100 is a volume-down button, the first control signal is a volume-down control signal, the second control signal is a power-on control signal or a screen-on control signal, and when the electronic device 10 is in a power-off or screen-locked state, the volume-down button can be used to control the electronic device 10 to power on or turn on the screen; when the electronic device 10 is in a screen-on state, the volume-down button controls the electronic device 10 to reduce the volume.

[0047] The first button 100 integrates at least two functions. When the electronic device 10 is in one state, the first button 100 can be used to control the electronic device 10 to implement one function. When the electronic device 10 is in another state, the first button 100 can be used to control the electronic device 10 to implement another function. One button can be used for multiple purposes, thereby reducing the number of physical buttons set on the electronic device 10 and enhancing the grip and appearance of the electronic device 10.

[0048] Specifically, when the electronic device 10 is in the off or locked screen state, the power-on control signal or the screen-on control signal can be triggered by pressing the volume-up button or the volume-down button to control the electronic device 10 to power on or turn on the screen. When the electronic device 10 is in the screen-on state, the corresponding volume-up control signal interface or the volume-down control signal can be triggered by pressing the volume-up button or the volume-down button to control the electronic device 10 to achieve the corresponding volume-up or volume-down. In this way, the volume-up button or the volume-down button integrates the function of the power-on button, which can realize both the volume control function and the power-on or screen-on function. The electronic device 10 can cancel the power-on button, simplify the structure of the electronic device, and enhance the grip and appearance of the electronic device 10; at the same time, the number of physical buttons is reduced, thereby reducing the structural gap between the physical buttons and the surrounding shell, thereby reducing the risk of system electrostatic failure of the electronic device.

[0049] Controlling the shutdown or screen-off of the electronic device 10 can be performed when the electronic device 10 is in the screen-on state. Therefore, the shutdown or screen-off of the electronic device 10 can be controlled by operating the display screen of the electronic device 10. For example, a virtual shutdown key can be set for control, or it can be set so that if the display screen is not operated within a preset time period, the electronic device 10 is shut down or the screen is turned off. In this way, the power-on or screen-on function of the power-on button is implemented by the volume-up button or the volume-down button, and the power-off or screen-off function of the power-off button is implemented by the virtual power-off key. The electronic device 10 can completely cancel the settings of the power-on button and the power-off button, further reducing the number of physical buttons.

[0050] In the embodiment of the present application, the electronic device 10 further includes a main chip 400, which is provided with a first control signal interface 410 and a second control signal interface 420. The main chip 400 is provided in a housing, and the first control signal interface 410 and the second control signal interface 420 can be GPIO ports of the main chip 400. The first control signal terminal 360 is connected to the first control signal interface 410, and the second control signal terminal 370 is connected to the second control signal interface 420.

[0051] The first button 100 is selectively connected to one of the first control signal interface 410 and the second control signal interface 420 through the switching circuit 300; when the first button 100 is connected to the first control signal interface 410, pressing the first button 100 can trigger the first control signal at the first control signal interface 410, and control a function of the electronic device 10 through the main chip 400; when the first button 100 is connected to the second control signal, pressing the second button 200 can trigger the second control signal at the second control signal interface 420, and control another function of the electronic device 10 through the main chip 400.

[0052] In this way, the first button 100 integrates at least two functions. When the electronic device 10 is in one state, the first button 100 can be used to control the electronic device 10 to implement one function. When the electronic device 10 is in another state, the first button 100 can be used to control the electronic device 10 to implement another function. One button can be used for multiple purposes, thereby reducing the number of physical buttons set on the electronic device 10 and enhancing the grip and appearance of the electronic device 10.

[0053] In the embodiment of the present application, the switching circuit 300 is used to connect the first button 100 and the second control signal interface 420 when the electronic device 10 is in the off state or the screen-locked state, and to connect the first button 100 and the first control signal interface 410 when the electronic device 10 is in the screen-on state. When the electronic device 10 is in the off state or the screen-locked state, the first button 100 can be used to control the electronic device 10 to implement one function, and when the electronic device 10 is in the screen-on state, the first button 100 controls the electronic device 10 to implement another function.

[0054] In the embodiment of the present application, the first button 100 is a volume plus button, the first control signal interface 410 is a volume plus control signal interface, and the second control signal interface 420 is a power-on control signal or a screen-on control signal interface. When the electronic device 10 is in a power-off or screen-locked state, the volume plus button can be used to control the electronic device 10 to power on or turn on the screen. When the electronic device 10 is in the screen-on state, the volume plus button controls the electronic device 10 to add volume.

[0055] Alternatively, in another embodiment of the present application, the first button 100 is a volume-down button, and the first control signal interface 410 is a volume-down control signal interface; the second control signal interface 420 is a power-on control signal or a screen-on control signal interface. When the electronic device 10 is in a power-off or screen-locked state, the volume-down button can be used to control the electronic device 10 to power on or turn on the screen. When the electronic device 10 is in a screen-on state, the volume-down button controls the electronic device 10 to reduce the volume.

[0056] The electronic device 10 of the present application integrates the function of a power button in the volume up button or the volume down button, which can serve two purposes in one button, thereby solving the problem that a power button must be set in existing electronic devices to realize the power on or screen light up function, thereby eliminating the setting of the power button of the electronic device 10 and enhancing the grip and appearance of the electronic device 10; at the same time, the number of physical buttons is reduced, thereby reducing the structural gap between the physical buttons and the surrounding shell, thereby reducing the risk of system electrostatic failure of the electronic device 10.

[0057] The shutdown or screen extinguishing of the electronic device 10 of the present application can be controlled by operating the display screen of the electronic device 10. For example, a virtual shutdown key can be set for control, or it can be set so that if the display screen is not operated within a preset time period, the electronic device 10 is shut down or the screen is extinguished.

[0058] Preferably, if Figure 6As shown, the key circuit of the electronic device 10 of the present application further includes a virtual power-off key 500, which is set in a drop-down menu of the electronic device 10. The virtual power-off key 500 is used to control the electronic device 10 to shut down or turn off the screen when the electronic device 10 is in a screen-on state. When the electronic device 10 of the present application is in a screen-on state, the electronic device 10 can be controlled to shut down or turn off the screen by operating the virtual power-off key 500 in the drop-down menu.

[0059] In this way, the power-on or screen-on function of the power-on button is realized by the volume-up button or the volume-down button, and the power-off or screen-off function of the power-off button is realized by the virtual power-off button 500, and the electronic device 10 can completely cancel the settings of the power-on button and the power-off button. The screen-on function can be realized by short pressing (pressing for less than 3 seconds) the volume-up button or the volume-down button used as the power-on button, and the power-off function can be realized by long pressing (pressing for more than 3 seconds) the volume-up button or the volume-down button used as the power-on button.

[0060] Furthermore, if Figure 2-4 As shown, the switch unit includes a first switch 340 and a second switch 350. The first switch 340 is connected between the first contact 310 and the second control signal terminal 370, and the second switch 350 is connected between the first contact 310 and the first control signal terminal 360. The conduction of the first contact 310 and one of the first control signal terminal 360 and the second control signal terminal 370 is controlled by turning on and off the first switch 340 and the second switch 350.

[0061] Specifically, when the electronic device 10 is in the shutdown or screen-locked state, the first switch 340 is closed and the second switch 350 is opened; when the electronic device 10 is in the screen-on state, the second switch 350 is closed and the first switch 340 is opened.

[0062] In the embodiment of the present application, in order to realize the control of the first switch 340 and the second switch 350, the switching circuit 300 also includes a switch control terminal 380, and the switch control terminal 380 is respectively connected to the first switch 340 and the second switch 350. When the electronic device 10 is in the off state or the screen lock state, the switch control terminal 380 can control the first switch 340 to close and control the second switch 350 to open. When the electronic device 10 is in the screen light state, the switch control terminal 380 can control the second switch 350 to close and control the first switch 340 to open.

[0063] Specifically, when the electronic device 10 is in the off or locked state, the switch control terminal 380 is used to input a first input signal, and the first input signal is used to control the first switch 340 to close and control the second switch 350 to open. When the electronic device 10 is in the bright screen state, the switch control terminal 380 is used to input a second input signal, and the second input signal is used to control the second switch 350 to close and control the first switch 340 to open.

[0064] The switch control terminal 380 can be connected to the display screen IO voltage of the electronic device 10. The display screen IO voltage is the power supply for the display screen. When the electronic device is in the shutdown or screen lock state, the display screen is not powered, so the display screen IO voltage signal is a low-level signal, the first input signal is a low-level signal, the first switch 340 is controlled to be closed, and the second switch 350 is controlled to be disconnected. When the electronic device is in the screen light state, the display screen is powered, so the display screen IO voltage signal is a high-level signal, the second input signal is a high-level signal, the second switch 350 is controlled to be closed, and the first switch 340 is controlled to be disconnected. The power supply signal when the electronic device is in the shutdown, screen lock or screen light state is used to control the closing and disconnection of the switch.

[0065] In the embodiment of the present application, the first switch 340 is a first triode, the second switch 350 is a second triode, the emitter of the first triode is connected to the first contact 310, the collector of the first triode is connected to the second control signal terminal 370, the base of the first triode is connected to the display screen IO voltage, the emitter of the second triode is connected to the first contact 310, the base of the second triode is connected to the display screen IO voltage, the collector of the second triode is connected to the first control signal terminal 360, and a third triode is further arranged between the base of the first triode and the display screen IO voltage, the base of the third triode is connected to the display screen IO voltage, the collector of the third triode is connected to the base of the first triode, the emitter of the third triode is grounded, and the base of the first triode is also connected to the first control signal terminal 360.

[0066] like Figure 3-4As shown, when the electronic device 10 is in the off or locked state, the display screen is not powered, the display screen IO voltage signal is a low level signal, the first input signal is a low level signal, the second transistor and the third transistor are cut off, the first control signal terminal 360 is a high level signal, and the first transistor is closed. At this time, the first contact 310 is connected to the second control signal terminal 370. When the first button 100 is pressed, the first contact 310 triggers the second control signal of the second control signal terminal 370, that is, the power-on control signal or the screen-on control signal, so that the electronic device 10 is turned on or The screen is on; when the electronic device 10 is in the screen-on state, the display screen is powered, the display screen IO voltage signal is a high-level signal, the second input signal is a high-level signal, the second transistor and the third transistor are closed, and when the third transistor is closed, the base of the first transistor is grounded, and the first transistor is cut off. At this time, the first contact 310 is connected to the first control signal terminal 360. When the first button 100 is pressed, the first contact 310 triggers the first control signal of the first control signal terminal 360, that is, the volume up or volume down control signal, so that the volume of the electronic device 10 is increased or decreased.

[0067] In this embodiment, the first switch 340 and the second switch 350 are described by taking a transistor as an example, but the present application is not limited to transistors. The first switch 340 and the second switch 350 can also be other switching devices as long as they can control the conduction and disconnection of the first contact 310 and the first control signal terminal 360 and the second control signal terminal 370.

[0068] In another embodiment of the present application, Figure 5 As shown, the switch unit is an analog switch chip 390 , and the analog switch chip 390 is used to control the first contact 310 to be conductive with one of the first control signal terminal 360 and the second control signal terminal 370 .

[0069] Specifically, as shown in the figure, the analog switch chip 390 includes a first pin 391, a second pin 392 and a third pin 393. The first pin 391 is connected to the first contact 310, the second pin 392 is connected to the second control signal terminal 370, and the third pin 393 is connected to the first control signal terminal 360. When the electronic device 10 is in the off or locked state, the first pin 391 is connected to the second pin 392, and the first pin 391 is disconnected from the third pin 393, so that the first contact 310 is connected to the second control signal terminal 370. When the electronic device 10 is in the bright screen state, the first pin 391 is connected to the third pin 393, and the first pin 391 is disconnected from the second pin 392, so that the first contact 310 is connected to the first control signal terminal 360.

[0070] Furthermore, the analog switch chip 390 also includes a control pin 394, the input of the control pin 394 is used to selectively connect the first pin 391 to one of the second pin 392 and the third pin 393, and when the electronic device 10 is in the off or locked state, the control pin 394 is used to input a first input signal, and the first input signal is used to control the first pin 391 to be connected to the second pin 392; when the electronic device 10 is in the bright screen state, the control pin 394 is used to input a second input signal, and the second input signal is used to control the first pin 391 to be connected to the third pin 393.

[0071] The control pin 394 can be connected to the display screen IO voltage of the electronic device 10. The display screen IO voltage is the power supply for the display screen. When the electronic device is in the shutdown or locked screen state, the display screen is not powered, so the display screen IO voltage signal is a low-level signal, and the first input signal is a low-level signal, which controls the first pin 391 to be connected with the second pin 392, and the first pin 391 to be disconnected from the third pin 393. At this time, the first contact 310 is connected with the second pin 392. When the first button 100 is pressed, the first contact 310 controls the second control signal of the second pin 392, that is, the power-on control signal or the screen-on control signal, so that the electronic device 10 is turned on or the screen is turned on; when the electronic device 10 is in the screen-on state, the display screen is powered, the display screen IO voltage signal is a high-level signal, and the second input signal is a high-level signal, which controls the first pin 391 to be connected with the third pin 393, and the first pin 391 to be disconnected from the second pin 392. At this time, the first contact 310 is connected to the third pin 393. When the first button 100 is pressed, the first contact 310 controls the first control signal of the third pin 393, that is, the volume up or volume down control signal, so that the volume of the electronic device 10 is increased or decreased.

[0072] In the embodiment of the present application, the key circuit of the electronic device 10 also includes a second key 200, which is a physical key. The second key 200 can be set on the side wall of the shell. The switching circuit 300 also includes a second contact 320 and a third control signal terminal 365. The second key 200 is connected to the second contact 320, and the second contact 320 is connected to the third control signal terminal 365. The third control signal terminal 365 is used to output a third control signal. The second key 200 triggers and controls the third control signal.

[0073] The main chip 400 is also provided with a third control signal interface, which may be a GPIO port of the main chip 400 , and the third control signal terminal 365 is connected to the third control signal interface.

[0074] The switching circuit also includes a third contact 330, which is grounded. The third contact 330 has no corresponding physical button. The third contact 330 is used in conjunction with the first contact 310 and the second contact 320. For example, pressing the first button 100 triggers the first contact 310. At this time, the first contact 310 and the third contact 330 are connected. Since the third contact 330 is grounded, when the first contact 310 and the third contact 330 are connected, the level signal of the first contact 310 is pulled down, thereby controlling the first control signal terminal or the second control signal terminal. Similarly, pressing the second button 200 triggers the second contact 320. At this time, the second contact 320 and the third contact 330 are connected. Since the third contact 330 is grounded, when the second contact 320 and the third contact 330 are connected, the level signal of the second contact 320 is pulled down, thereby controlling the third control signal terminal.
