[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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 creative work are within the scope of protection of this application.

In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the objects connected before and after are in an "or" relationship.

[0032] In the description of the present invention, it is necessary to understand that the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The key structure according to the embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, the key structure of the embodiment of the present invention includes:

[0036] A key module 1; an OR gate element 2, wherein the output end of the OR gate element 2 is connected to the key module 1; a piezoelectric sensing device 3, wherein the piezoelectric sensing device 3 is connected to the first input end of the OR gate element 2;

[0037] A processor 4, wherein the processor 4 is connected to the second input terminal of the OR gate element 2;

[0038] The OR gate element 2 enables the key module 1 according to the first enable signal input by the piezoelectric sensing device 3 or the second enable signal input by the processor 4 .

[0039] In this embodiment, the key module 1 can be a pressure-sensitive key module, which is arranged on an electronic device and can be operated by a user, such as a power on / off key module. The processor 4 can be a central processing unit (CPU). The output end of the OR gate element 2 is connected to the key module 1, and is used to output an enable signal to the key module 1, so that the key module 1 is powered on and works. The input end of the OR gate element 2 is connected to the piezoelectric sensing device 3 and the processor 4, and the piezoelectric sensing device 3 can input a first enable signal to the OR gate element 2, and the processor 4 can input a second enable signal to the OR gate element 2.

[0040] The piezoelectric sensing device 3 is a sensing device that can convert mechanical energy into electrical energy, such as piezoelectric ceramics. The user can operate the piezoelectric sensing device 3, and the piezoelectric sensing device 3 converts pressure into electrical energy to enable the key module 1, so that the key module 1 is powered on and works. The processor 4 can enable the key module 1 through the OR gate element 2, so that the key module 1 is powered on and works.

[0041] In the embodiment of the present application, there are two ways to enable the key module 1: the first way is enabled by the processor 4, and the second way is enabled by the piezoelectric sensing device 3; the OR gate element 2 enables the key module 1 according to the second enable signal of the processor 4 or the first enable signal of the piezoelectric sensing device 3. Taking the key module as the power on / off key module of the electronic device as an example, when the electronic device is in working state, the central processor 4 can output the second enable signal, and the OR gate element 2 receives the enable signal and outputs a high level to enable the key module 1, and constantly detects the key information of the user on the power on / off key in the key module 1, so as to realize operations such as lighting up the screen and turning the machine on and off.

[0042] When the electronic device is in a non-working state, the processor 4 can cancel the output of the second enable signal, and the key module 1 stops working. In the non-working state (for example, the power-off state, the screen-off time exceeds a time threshold), when the user needs to power on the key module 1, the piezoelectric sensing device 3 can be operated. The piezoelectric sensing device 3 converts the pressure applied by the user into electrical energy, outputs the first enable signal to the OR gate element 2, and enables the key module 1 through the OR gate element 2 to power it on, thereby detecting the user's key information on the power button in the key module 1.

[0043] In the embodiment of the present application, a piezoelectric sensing device and a processor are connected to a key module through an OR gate element, and the OR gate element enables the key module according to a first enable signal input by the piezoelectric sensing device or a second enable signal input by the processor. In this way, when the electronic device is in a non-working state, the processor can cancel the enablement of the key module, and the user can operate the piezoelectric sensing device to convert pressure into electrical energy to enable the key module, thereby saving power consumption of the key module of the electronic device when it is in a non-working state.

[0044] Alternatively, if Figure 2 As shown, the button module 1 includes: a pressure-sensitive button 11, a microcontroller unit 12 (MCU) connected to the pressure-sensitive button 11, and a linear regulator 13 (Low Dropout Regulator, LDO) connected to the microcontroller unit 12; the output end of the OR gate element 2 is connected to the enable pin of the linear regulator 13.

[0045] like Figure 3 As shown, the working principle of the pressure-sensitive key 11 is to set a pressure sensor 31 on the key panel. The pressure sensor 31 can generate a corresponding analog signal according to the force of the key panel, and send the analog signal to the microcontroller unit 12 for amplification, analog-to-digital conversion and algorithm processing. Finally, the microcontroller MCU outputs the corresponding key information to the system on chip 32 (System on Chip, SOC); when the user operates the pressure-sensitive key, the deformation of the key panel is large, resulting in a large change in the analog signal. When the user does not operate the pressure-sensitive key, the deformation of the key panel is small, resulting in a small change in the analog signal, so that it can be identified whether the pressure-sensitive key 11 is pressed. The pressure-sensitive key 11 requires the microcontroller unit 12 to perform detection and processing, so the pressure-sensitive key 11 needs to increase additional power consumption.

[0046] When the electronic device is in a non-working state (such as being turned off or the screen being off for more than a time threshold), in order to ensure that the microcontroller unit 12 can be powered on and detect the signal of the pressure-sensitive button 11 when the user needs the electronic device to work, it is necessary to ensure that the linear regulator 13 can supply power to the microcontroller unit 12 when there is a power-on demand. Therefore, the piezoelectric sensing device 3 is provided, and the user can operate the piezoelectric sensing device 3. The piezoelectric sensing device 3 can convert the user's pressure into electrical energy, enabling the linear regulator 13, and the linear regulator 13 supplies power to the microcontroller unit 12.

[0047] For example: when the electronic device is in a normal working state, the processor 4 enables the linear regulator 13, the linear regulator 13 supplies power to the micro control unit 12, and the micro control unit 12 detects the pressure information applied to the pressure-sensitive key 11; when the electronic device is turned off for more than a preset time, the processor 4 is controlled to cancel the enabling of the linear regulator 13, and the linear regulator 13 stops outputting voltage, that is, stops supplying power to the micro control unit 12, and the micro control unit 12 stops working, saving power consumption when the electronic device is not working; when the user wants to turn on the device, the piezoelectric sensing device 3 can be operated, and the piezoelectric sensing device 3 converts the pressure applied by the user into electrical energy, enables the linear regulator 13, and enables the linear regulator 13 to supply power to the micro control unit 12, and the micro control unit 12 is powered on and starts to detect the power button (that is, the pressure-sensitive key 11); the user operates the power button, and the micro control unit 12 detects the key information of the power button and completes the power-on work.

[0048] After the electronic device is turned on and started successfully, the electronic device is in working state, the processor 4 relays to enable the linear regulator 13, the linear regulator 13 keeps supplying power to the micro control unit 12, ensures the power button (i.e. the pressure-sensitive button 11) works, and detects external key signals at any time. When the processor 4 detects a long standby time (configurable time), the linear regulator 13 can be disabled, the linear regulator 13 stops outputting voltage, and the micro control unit 12 stops working, achieving the function of shutting down or standby power saving.

[0049] It should be noted that the pressure-sensitive button 11 in this embodiment can be a power button or other buttons, which is not limited here.

[0050] The first end of the piezoelectric sensing device 3 is exposed on the surface of the electronic device, and the second end of the piezoelectric sensing device 3 is connected to the first input end of the OR gate element 2. The piezoelectric sensing device 3 and the pressure-sensitive button 11 can be arranged on the same surface of the electronic device. The piezoelectric sensing device 3 can be a device of the same type as the pressure-sensitive button 11, such as piezoelectric ceramics. The position of the piezoelectric sensing device 3 can be set according to the user's usage habits, such as being set around the pressure-sensitive button 11. Furthermore, it can be set at a position adjacent to the pressure-sensitive button 11 to facilitate user operation.

[0051] The processor 4 is also connected to the microcontroller unit 12, and is used to receive the key information detected by the microcontroller unit 12. The processor 4 includes a detection unit for detecting the working state of the electronic device, which is used to detect the working state of the electronic device, for example: when the duration of the electronic device turning off the screen or shutting down reaches a preset duration, the electronic device is considered to be in a non-working state, and the processor 4 cancels the enabling of the linear regulator 13, and the user operates the piezoelectric sensing device 3 to enable the linear regulator 13; when the electronic device is in a screen-on state, turns off the screen or shuts down for a duration that does not reach a preset duration, the electronic device is considered to be in a working state, and the processor 4 enables the linear regulator 13. Among them, the processor 4 is connected to the second input end of the OR gate element 2 through a general purpose I / O port (GPIO). That is, the processor 4 outputs an enable signal through the GPIO port.

[0052] In the embodiment of the present application, a piezoelectric sensing device and a processor are connected to a key module through an OR gate element, and the OR gate element enables the key module according to a first enable signal input by the piezoelectric sensing device or a second enable signal input by the processor. In this way, when the electronic device is in a non-working state, the processor can cancel the enablement of the key module, and the user can operate the piezoelectric sensing device to convert pressure into electrical energy to enable the key module, thereby saving power consumption of the key module of the electronic device when it is in a non-working state.

[0053] The control method of the key structure provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0054] like Figure 4 As shown, an embodiment of the present application provides a control method of a key structure, which is applied to the above-mentioned key structure, including:

[0055] Step 401: Obtain the working status of the electronic device.

[0056] Step 402: When the electronic device is in working state, send a second enable signal to the OR gate element;

[0057] Step 403: When the duration of the electronic device being in the non-working state reaches a preset duration, stop sending the second enable signal.

[0058] The processor is used to obtain the working state of the electronic device, for example: when the electronic device is in the screen-on state, or the screen-off or shutdown time of the electronic device does not reach the preset time, the electronic device is considered to be in the working state, and the processor outputs the second enable signal to enable the linear regulator, so that the linear regulator powers the microcontroller. When the screen-off or shutdown time of the electronic device reaches the preset time, the electronic device is considered to be in the non-working state, and the non-working state time reaches the preset time, then the processor stops sending the second enable signal, that is, cancels the enabling of the linear regulator, the linear regulator stops powering the microcontroller, and the microcontroller stops working. At this time, if the user wants to operate the pressure-sensitive button (such as power on and off), it is necessary to operate the piezoelectric sensing device first, and the piezoelectric sensing device converts the pressure applied by the user into electrical energy to enable the linear regulator, then the linear regulator powers the microcontroller, the microcontroller is powered on, and the microcontroller starts to detect the pressure-sensitive button. The user presses the pressure-sensitive button, and the microcontroller detects the button information (such as the power on and off button information) and completes the corresponding button work.

[0059] It should be noted that there is no order between step 402 and step 403, and the processor determines the execution step according to the current working state of the electronic device.

[0060] The method may also include: when the duration of the electronic device being in a non-working state does not reach a preset duration, sending the second enable signal to the OR gate element. When the duration of the electronic device being in a non-working state does not reach a preset duration, for example, the duration of the electronic device being off the screen or shutting down does not reach the preset duration, the processor still enables the linear regulator, for example: the preset time is set to 5 minutes, and the current screen-off duration of the electronic device is 1 minute. At this time, the processor still outputs the second enable signal, and the linear regulator supplies power to the microcontroller unit, and the microcontroller unit always detects the key information of the pressure-sensitive key; when the current screen-off duration of the electronic device exceeds 5 minutes, the processor stops outputting the second enable signal, that is, cancels the enabling of the linear regulator, and the linear regulator stops supplying power to the microcontroller unit, and the microcontroller unit stops working, thereby saving standby power consumption; at this time, the user can operate the piezoelectric sensing device, and the piezoelectric sensing device converts pressure into electrical energy to enable the linear regulator, and the linear regulator supplies power to the microcontroller unit.

[0061] In an embodiment of the present application, a processor detects the working state of an electronic device. When the electronic device is in a working state, the processor sends a second enable signal to the OR gate element to enable a pressure-sensitive key module. When the electronic device is in a non-working state, the processor stops sending the second enable signal, i.e., cancels the enabling of the key module. At this time, the user can operate the piezoelectric sensing device to convert pressure into electrical energy to enable the key module, thereby saving power consumption of the key module when the electronic device is in a non-working state.

[0062] It should be noted that the control method of the key structure provided in the embodiment of the present application can be executed by a control device of the key structure, or a control module in the control device of the key structure for executing the control method of the key structure. In the embodiment of the present application, the control device of the key structure executing the control method of the key structure is taken as an example to illustrate the control device of the key structure provided in the embodiment of the present application.

[0064] An acquisition module 510 is used to acquire the working status of the electronic device;

[0065] A first sending module 520, configured to send a second enabling signal to the OR gate element when the electronic device is in a working state;

[0066] When the duration of the electronic device being in the non-working state reaches a preset duration, the sending of the second enable signal is stopped.

[0067] In an embodiment of the present application, a processor detects the working state of an electronic device. When the electronic device is in a working state, the processor sends a second enable signal to the OR gate element to enable a key module. When the electronic device is in a non-working state, the processor stops sending the second enable signal, i.e., cancels the enabling of the key module. At this time, the user can operate the piezoelectric sensing device to convert pressure into electrical energy to enable the key module, thereby saving power consumption of the key module when the electronic device is in a non-working state.

The operating system may be an Android operating system, an iOS operating system, or other possible operating systems, which are not specifically limited in the embodiment of the present application.
