[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] In order to solve the above technical problems, the embodiments of the present disclosure provide a button and an electronic device, which can be configured as an electronic device with buttons such as a smart phone, a tablet computer, a smart watch, a smart bracelet, etc.

[0039] The key provided by the present disclosure has the inventive concept that a pressure sensor senses the pressing pressure and outputs a sensing voltage matching the pressing pressure, and the sensing voltage can be used to generate a vibration drive signal; the vibration device can generate a vibration feedback matching the sensing voltage when receiving the vibration drive signal. In this way, the vibration feedback can make the user know the size of the pressing pressure, achieve the effect of pressure grading, and help improve the user experience.

[0040] The present disclosure provides a key, see Figure 1 The button 10 includes a pressure sensor 12 and a vibration device 11.

[0041] After power is supplied, the pressure sensor 12 detects whether the pressure changes and outputs a sensing voltage when the pressure changes. The sensing voltage can be used to generate a vibration drive signal. It is understandable that the sensing voltage can be output to a processor of an electronic device where the key is located or a processing unit of the key to generate a vibration drive signal. For example, a table can be pre-stored, in which the correspondence between the sensing voltage and the vibration drive signal is stored; by querying the table, the vibration drive signal corresponding to the sensing voltage can be determined.

[0042] The vibration device 11 can receive the vibration driving signal and generate vibration feedback matching the sensing voltage.

[0043] In one embodiment, the pressure sensor 12 can be implemented by a screen-printed Wheatstone bridge sensor or an IC packaged pressure sensing chip. In one example, the pressure sensor 12 is implemented by a screen-printed Wheatstone bridge sensor. Figure 2The Wheatstone bridge sensor includes a first resistor R1, a second resistor R2, a third resistor R3 and a fourth resistor R4. The first resistor R1, the second resistor R2, the third resistor R3 and the fourth resistor R4 are connected in series in sequence to form a loop, the connection between the first resistor R1 and the second resistor R2 is used as a power supply terminal VCC, the connection between the third resistor R3 and the fourth resistor R4 is used as a ground terminal GND, the connection end of the first resistor R1 and the third resistor R3 is used as a first output terminal Vm+, and the connection end of the second resistor R2 and the fourth resistor R4 is used as a second output terminal Vm-.

[0044] The voltage values ​​of the first output terminal Vm+ and the second output terminal Vm- are respectively shown in equations (1) and (2):

[0045] Vm+=Vcc*(R3 / (R1+R3)) (1)

[0046] Vm-=Vcc*(R4 / (R2+R4)) (2)

[0047] Assume that the resistance values ​​of the first resistor R1 and the fourth resistor R4 are fixed, and the resistance values ​​of the second resistor R2 and the third resistor R3 can change. When there is no external force applied to the pressure sensor 12, the resistance values ​​of the second resistor R2 and the third resistor R3 will not change. At this time, Vm+-Vm-=0, and no sensing voltage is output; when an external force is applied to the pressure sensor 12, the resistance values ​​of the second resistor R2 and the third resistor R3 will change. At this time, Vm+-Vm-≠0 has a voltage difference, and the sensing voltage is output.

[0048] Therefore, the working principle of the pressure sensor 12 can be: when different levels of external force are applied to the pressure sensor 12, the pressure sensor 12 produces different deformation amounts, the resistance values ​​of the second resistor R2 and the third resistor R3 produce different resistance value changes, and finally output different sensing voltages.

[0049] It should be noted that, in this embodiment, when the pressure sensor 12 is implemented using a Wheatstone bridge sensor, it can detect a pressure of 5 gf to 10 gf, which can improve the recognition sensitivity.

[0050] In another example, multiple pressure sensors 12 can be provided, for example, 2 to 4; and each pressure sensor is provided at a different location, so the location where the external force is applied can be located through multiple sensing voltages, and the pressing location can be located through multiple sensing voltages when the user presses a key. In this way, by locating the pressing location, the target scene can be switched to, such as focusing, shooting, lighting the screen, increasing / decreasing the volume, etc., thereby enriching the functions of the key.

[0051] See also Figure 3The key 10 includes a key cap 41, a key rubber layer 42, a key column 43 and a fixing structure 44. The key cap 41 is arranged on a first side of the key rubber layer 42; the first end of the key column 43 is arranged in contact with the second side of the key rubber layer 42; the second end of the key column 43 is arranged in contact with the first side of the pressure sensor 12, and the second side of the pressure sensor 12 is fixed on the fixing structure 44.

[0052] It should be noted that, taking the axial direction Z of the key 10 (described from top to bottom) as an example, Figure 3 The manner in which the key 10 is divided into the first side and the second side from top to bottom is illustrated.

[0053] In one example, the key rubber layer 42 may be made of insulating material, such as plastic, glass fiber, etc. If the insulating material and elasticity can be provided, the corresponding solution falls within the protection scope of the present disclosure.

[0054] Continue to see Figure 3 and Figure 4 The first end of the button column 43 contacts the button rubber layer 42, and the second end contacts the pressure sensor 12. The number of the button column 43 can be one or more. In one example, the second side of the button rubber layer 42 is provided with a protrusion 421, and each protrusion 421 contacts the button column 43 accordingly, so as to ensure that the pressure is transmitted to the button column 43 through the protrusion 421, thereby ensuring the pressing effect.

[0055] In one embodiment, the key 10 further includes a sealing ring. The sealing ring is sleeved on the key column 43, clamped between the fixing structure 44 and the key column 43, and configured to seal the gap of the fixing structure 44 through which the key column 43 passes. Figure 4 The fixing structure 44 is provided with a through hole 441, through which the button column 43 can pass, and can move back and forth in a direction parallel to the axial direction of the button 10. The sealing ring 61 is sleeved on the outside of the button column 43 and the inside of the through hole 441, sealing the gap between the button column 43 and the through hole 441. In this way, moisture in the direction of the button cap 41 cannot penetrate the button column 43 into the pressure sensor, thereby ensuring the normal operation of the pressure sensor.

[0056] In one embodiment, see Figure 5, the fixed structure 44 includes a supporting steel sheet 442 and a fixing bracket 443. The fixing bracket 443 is implemented by a hollow structure. The hollow structure means that along the axial direction of the fixing bracket 443, the middle area of ​​the fixing bracket 443 is a receiving space, or in other words, the fixing bracket 443 is a quadrilateral structure surrounded by a bracket material. In one example, the fixing bracket 443 is provided with a card slot 4431 at the middle position inside the receiving space. The supporting steel sheet 442 can be clamped into the receiving space of the fixing bracket 443, and the surface of the supporting steel sheet 442 is perpendicular to the axial direction of the key 10 after being clamped. In this way, a first mounting groove with an opening toward the first side and a second mounting groove with an opening toward the second side can be formed between the supporting steel sheet 442 and the fixing bracket 443. The first mounting groove is used to install the pressure sensor 12. By arranging the pressure sensor 12 in the first mounting groove, its movement can be avoided, ensuring that the key column 43 transmits the pressure to the preset position of the pressure sensor 12, achieving a one-to-one matching of pressure and deformation, that is, improving the accuracy of pressure detection. The second installation groove is used for installing the vibration device 11 , and the following embodiments describe the relevant contents of the vibration device 11 .

[0057] It should be noted that the wiring terminals of the pressure sensor can be extended through the gap between the supporting steel sheet 442 and the fixed bracket 443 and the wiring groove or gap of the fixed structure by extending the FPC circuit or leading out the connecting wire, so as to achieve the effect of electrical connection with the control unit.

[0058] In another embodiment, see Figure 5 , the button 10 also includes a pressing layer 71, a supporting layer 72 and a limiting layer 73. The pressing layer 71 is provided with protrusions 711 on both sides of the first direction X. The first direction is perpendicular to the axial direction of the button 10. The protrusion 711 of the pressing layer 71 is movably connected to the supporting layer 72, and the rotation axis Y is respectively perpendicular to the first direction X and the axial direction Z of the button 10. The above-mentioned movable connection can be riveted or the limiting axis is inserted after the pressing layer is aligned with the supporting layer, etc., which can be set according to the specific scene. The supporting layer 72 is attached to the limiting layer 73, and the area of ​​the limiting layer 73 is smaller than the supporting layer 72; the pressure sensor 12 is arranged in the space formed by the pressing layer 71 and the supporting layer 72 and fixed to the supporting layer 72. In this way, the pressing layer 71 is configured to deform when pressed by an external force; the supporting layer 72 is configured to deform following the deformation of the pressing layer 71; the pressure sensor 12 is configured to output a sensing voltage corresponding to the deformation amount when detecting the deformation of the supporting layer 72. By providing the pressing layer 71 , the supporting layer 72 and the limiting layer 73 , the deformation degree of the pressure sensor 12 can be increased, thereby achieving the effect of increasing the detection pressure variation range, and providing a basis for pressure grading.

[0059] It should be noted that, since the support layer 72 changes with the pressing layer 71, Figure 6In the example direction, when the support layer 72 is deformed, the two sides (in the first direction) move downward, and at most reach the first side surface of the fixing bracket 443, that is, the maximum deformation distance of the support layer 72 is the thickness of the limiting layer. In other words, the pressure detection range of the pressure sensor 12 is adjusted by adjusting the thickness of the limiting layer, so as to meet the needs of different scenarios.

[0060] Considering that the pressure sensor needs to be powered, the embodiment of the present disclosure provides the following power supply methods, including:

[0061] In one example, see Figure 6 The pressure sensor 12 is electrically connected to the battery unit 16. At this time, a power switch 81 can be provided for the pressure sensor 12. The power switch 81 can include but is not limited to a transistor or a MOS tube, etc., which can be provided on a circuit board of the pressure sensor.

[0062] In one example, a signal holding unit is provided between the pressure sensor 12 and the battery unit 16. The function of the signal holding unit is to start working after the pressure sensor is powered on, and to maintain the control signal output to the control end of the power supply switch 81 when there is current in the power supply circuit.

[0063] In some possible examples, the signal holding unit may be implemented by a capacitor, an RC delay circuit, etc. In this case, the capacitor or the RC delay circuit may be connected across the battery unit and the control end of the power switch 81. Figure 7 The signal holding unit 91 can be implemented by a capacitor Cst. Due to the pumping function of the capacitor Cst, a control voltage can be provided to the power switch 81 to achieve the effect of keeping the power switch 81 in the on state.

[0064] In some other possible examples, the signal holding unit 91 can also be implemented by a MOS tube, the gate and source of which are electrically connected to the pressure sensor 12, and the drain of which is electrically connected to the control end of the power switch 81. After receiving the power supply voltage, the power switch 81 switches to the on state, at which time there is current in the power supply circuit between the pressure sensor 12 and the battery unit 16; when there is current in the power supply circuit, the gate of the MOS tube of the signal holding unit 91 is powered, and it switches to the on state; since the MOS of the signal holding unit 91 is in the on state, the power switch 81 is in the on state, and the signal holding unit 91 continues to be in the on state. At this time, the power supply circuit maintains the power supply state.

[0065] When the pressure sensor does not detect pressure for a certain period of time (settable, such as 1 to 3 minutes), an opposite stop voltage can be provided to the control end of the power switch 81, thereby disconnecting the power supply circuit. The above stop voltage can be provided by the control unit 14 of the button 10. For example, the power control pin of the control unit 14 is electrically connected to the control end of the power switch 81 or the gate of the MOS tube of the signal holding unit 91. After the stop voltage is applied, the power switch 81 is switched to the disconnected state, and finally the power supply circuit is disconnected.

[0066] In another example, see Figure 8 , the button also includes a control unit 14. The control unit 14 can be implemented by a device with processing functions such as an MCU, a single-chip microcomputer, etc. The control unit 14 is electrically connected to the pressure sensor 12 and the vibration device 11 respectively. The control unit 14 is configured to generate a power supply control signal to the pressure sensor 12 during operation. In addition, the control unit 14 is also configured to receive a sensing voltage output by the pressure sensor 12. Among them, how the control unit 14 processes the sensing voltage can refer to the content of the subsequent method embodiment, which will not be explained here.

[0067] It should be noted that Figure 8 The example shows a scenario where the battery unit 16 supplies power to the control unit 14 and the pressure sensor 12 respectively, and then the control unit 14 can control the pressure sensor 12. In some possible scenarios, the battery unit 16 can supply power to the control unit 14, and then the control unit 14 supplies power to the pressure sensor as needed, that is, the battery unit 16 no longer supplies power to the pressure sensor 12 alone.

[0068] In one embodiment, see Figure 5 and Figure 8 , the vibration device 11 in the button is electrically connected to the control unit 14. In one example, the vibration device 11 can be arranged in the second mounting groove, and the second mounting groove is located on the second side of the supporting steel sheet 442; or in other words, after the supporting steel sheet 442 is clamped, the hollow area is divided into two to obtain a first mounting groove and a second mounting groove, and the pressure sensor is installed in the first mounting groove and the vibration device 11 is installed in the second mounting groove.

[0069] In one example, the vibration device 11 can be implemented by a linear motor, a rotary motor or a piezoelectric ceramic, and can be set according to the specific scenario. In one example, the vibration device 11 can be implemented by a piezoelectric ceramic to reduce the volume of the key 10. When the vibration device 11 is implemented by a piezoelectric ceramic, it can be fixed in the second mounting groove by fitting, snapping, squeezing, etc., so that when the vibration device 11 vibrates, it can drive the key cap to vibrate and transmit it to the user's finger.

[0070] In this embodiment, the control unit 14 is further configured to generate a vibration drive signal when receiving the sensing voltage, and the vibration drive signal may be a triangular signal or a square wave signal. The vibration device 11 is further configured to vibrate at a set frequency when receiving the vibration drive signal. The set frequency has a value range of 5 to 1000 Hz, such as 50 Hz, and can be set according to specific scenarios.

[0071] In one example, the intensity of the vibration feedback of the vibration device 11 can be kept constant, with the purpose of providing a feedback signal of successful pressing to the user.

[0072] In another example, the intensity of the vibration feedback of the vibration device 11 corresponds one-to-one to the sensing voltage, that is, the vibration feedback corresponds one-to-one to the detected pressure value, which aims to provide different vibration feedbacks to the user to remind the user of the current pressing pressure.

[0073] Based on the contents of the above embodiments, it can be seen that the key has a simple structure and is easy to be installed on an electronic device. It can realize pressing position positioning, pressure grading, sliding detection, etc., so as to enrich the key functions while reducing power consumption.

[0074] The present disclosure also provides an electronic device, which includes a Figures 1 to 8 The electronic device may include one, two or more of the above-mentioned buttons, which may be applicable to side button applications, target scenarios such as single button, double button, single-side button, double-side button, and target scenarios such as volume button, power button, and function button such as camera button.

[0075] Take setting one button as an example, see Fig. 9 The button 10 can be arranged on one side of the electronic device. Fig. 9 The example below shows the effect of the setting on the right.

[0076] Take setting 2 buttons as an example, see Fig.10 , the two buttons can be set on both sides of the electronic device. Fig.11 , two buttons can be set on the same side of the electronic device at the same time, Fig.11 The example below shows the effect of the setting on the right.

[0077] In one example, after receiving the sensing voltage, the control unit can generate a vibration driving signal and send it to the vibration device. When the vibration device receives the vibration driving signal, it vibrates at a set frequency, so that the key is triggered and there is a vibration feedback effect.

[0078] In another example, after receiving the sensing voltage, the control unit can determine the pressure level corresponding to the sensing voltage. The pressure level can be divided according to the pressure size. For example, when the pressure is 1 to 2g (expressed by mass), the pressure level is level 1, and when the pressure is 2 to 3g, the pressure level is level 2, and so on. It can be set according to the specific scenario. Then, based on the correspondence between the pressure level and the vibration drive signal, the control unit can generate a vibration drive signal according to the pressure level, and the above vibration drive signal is configured to drive the vibration device to vibrate at a set frequency.

[0079] In one example, when the button is set in an electronic device, the button can also output the pressure level to the processor of the electronic device. At this time, the processor of the electronic device can switch to the target scene according to the pressure level. Among them, the target scene can include at least one of the following: focusing, taking pictures, lighting up the screen, turning on the phone, and adjusting the volume.

[0080] In one embodiment, the button can be restored to a dormant state. When the sensing voltage is not detected, the control unit starts timing. When the sensing voltage is not received within a first set time, the control unit can switch to an idle state, at which time the power consumption of the pressure sensor and the control unit is first reduced; when the sensing voltage is not received within a second set time, the control unit can switch to a dormant state to further reduce power consumption.

[0081] In one embodiment, when there are multiple pressure sensors in the key, the control unit can sense the voltage output by each pressure sensor in each detection cycle. Then, the control unit can locate the pressed position according to the multiple sensed voltages in the same detection cycle. It is also possible to determine operations such as pressing or sliding according to the pressed position. Then, the control unit can provide the above-mentioned pressed position to the processor of the electronic device. The processor can switch to the target scene according to the pressed position, such as adjusting the volume, lighting the screen, and focusing.

[0082] Considering that the key is applied to an electronic device, the key control unit can be implemented by a processor of the electronic device, or the key control unit forwards the sensing voltage to the processor of the electronic device. Then, the processor of the electronic device can locate the pressing position and / or pressure level according to the sensing voltage, and the solution of the present disclosure can also be implemented.
