Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a button module, a button signal recognition method, and an electronic device. Background Technology

[0002] To improve the utilization of buttons in electronic devices, different number of presses of the same button can trigger different responses from the electronic device. For example, a single press of the power button can lock the screen, while pressing the power button five times consecutively can trigger emergency contact and send an emergency call.

[0003] In related technologies, buttons, conductive springs, and circuit boards are arranged sequentially. Pressing the button causes it to push the conductive spring into contact with the circuit board, enabling the button module to emit an electrical signal. However, when a user holds the electronic device or an object squeezes it, the button may be repeatedly pressed, causing the conductive spring and circuit board to mis-touch. This results in a high rate of false touches in the button module of these technologies, causing the electronic device to perform operations not intended by the user. Summary of the Invention

[0004] The purpose of this application is to provide a button module, a button signal recognition method, and an electronic device that can solve the technical problem of high false touch rate of button modules.

[0005] In a first aspect, embodiments of this application provide a button module, including:

[0006] The buttons, conductive springs, and circuit board are arranged sequentially along the first direction;

[0007] A buffer assembly includes a buffer layer and an expandable fluid. The buffer layer is disposed on the side of the circuit board away from the button. The buffer layer has a sealed receiving cavity. The expandable fluid is filled into the receiving cavity. The expandable fluid and the conductive spring are spaced apart along a first direction.

[0008] When the button module is in the first state, the conductive spring does not bear the button press, and the conductive spring is spaced apart from the conductive lines of the circuit board.

[0009] When the button module is in the second state, the conductive spring is subjected to button pressing and generates a shear rate greater than or equal to the first rate. The viscosity of the expansive fluid is greater than or equal to the first viscosity. The conductive spring deforms in the direction away from the button and makes contact with the conductive lines of the circuit board to conduct electricity.

[0010] When the button module is in the third state, the conductive spring is subjected to button pressure and generates a shear rate less than the first rate. The viscosity of the expansive fluid is less than the first viscosity. The conductive spring is spaced from the conductive lines of the circuit board. The conductive spring and the circuit board deform together in the direction away from the button.

[0011] Secondly, embodiments of this application provide a method for recognizing key signals, applied to an electronic device having a key module as provided in the first aspect. The method includes:

[0012] If the button module is detected to output n first press signals within a first preset time period, calculate the interval between the first press signals with adjacent output times, where n≥2;

[0013] Whether to respond to n first press signals is determined based on the duration of the first press signal and the interval duration.

[0014] Thirdly, embodiments of this application provide an electronic device, which includes a processor, a memory, and a button module as provided in the first aspect. The memory stores programs or instructions that can run on the processor, and when the programs or instructions are executed by the processor, they implement the steps of the method as provided in the first aspect.

[0015] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, and when the program or instructions are executed by a processor, they implement the steps of the method as described in the second aspect.

[0016] Fifthly, embodiments of this application provide a chip, which includes a processor and a communication interface. The communication interface and the processor are coupled, and the processor is used to run programs or instructions to implement the method as described in the second aspect.

[0017] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method as described in the second aspect.

[0018] In this embodiment, by setting the expandable fluid and the conductive spring to be spaced apart along a first direction, the expandable fluid can exhibit a solid-like state at a shear rate greater than or equal to a first rate. The expandable fluid supports the circuit board and fixes it, causing the conductive spring to deform away from the button and make contact with the conductive lines of the circuit board, thereby outputting an electrical signal for the user's rapid button press. Alternatively, the expandable fluid can exhibit a liquid-like state at a shear rate less than the first rate, with the expandable fluid, buffer layer, circuit board, and conductive spring deforming together, so that the conductive spring and the conductive lines of the circuit board are not connected. Thus, the signal output of the button module is not affected by the user's slow button press or the continuous pressure of an object on the button, reducing the false touch rate of the button module.

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The button module, button signal recognition method, and electronic device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This application provides a button module, which includes a button 1, a conductive spring 2 and a circuit board 3 arranged sequentially along a first direction X, and a buffer assembly 4. The buffer assembly 4 includes a buffer layer 41 and an expandable fluid 43. The buffer layer 41 is disposed on the side of the circuit board 3 away from the button 1. The buffer layer 41 has a sealed receiving cavity 42. The expandable fluid 43 is filled into the receiving cavity 42. The expandable fluid 43 and the conductive spring 2 are spaced apart along the first direction X.

[0034] When the button module is in the first state, the conductive spring 2 is not pressed by the button 1, and the conductive spring 2 and the conductive lines of the circuit board 3 are spaced apart.

[0035] When the button module is in the second state, the conductive spring 2 is pressed by the button 1 and generates a shear rate greater than or equal to the first rate. The viscosity of the expansive fluid 43 is greater than or equal to the first viscosity. The conductive spring 2 deforms in the direction away from the button 1 and contacts the circuit board 3 to conduct electricity.

[0036] When the button module is in the third state, the conductive spring 2 is pressed by the button 1 and generates a shear rate less than the first rate. The viscosity of the expansive fluid 43 is less than the first viscosity. The conductive spring 2 is separated from the conductive line of the circuit board 3. The conductive spring 2 and the circuit board 3 deform together in the direction away from the button 1.

[0037] The button module can be installed in electronic devices such as mobile phones, tablets, laptops, PDAs, and in-vehicle devices; this application does not impose specific limitations on its implementation. The button module can serve as the input module of the entire device or as one of multiple input units within an input module. The input module can be a keyboard, a screen-off control button, a volume control button, a brightness control button, etc. Multiple input units can be multiple buttons located on a keyboard. The following explanation uses a button module installed in a mobile phone, with the button module being the power button, as an example.

[0038] Button 1 is the component for user interaction with the button module. Users can operate the button module through button 1 to facilitate the operation of electronic devices.

[0039] The conductive spring 2 is partially or entirely made of conductive material, and it is positioned opposite to the conductive lines in the circuit board 3. Under external force, the conductive spring 2 deforms, and the deformed spring 2 contacts the conductive lines on the circuit board 3 to form a circuit. The circuit board 3 then outputs a changing electrical signal. A processor connected to the circuit board 3 analyzes this electrical signal to execute the corresponding operation. The conductive spring 2 can be a circular metal spring, a cross-shaped metal spring, a triangular metal spring, an elliptical metal spring, etc.

[0040] The buffer layer 41 is made of a material with good deformation capacity and elasticity, such as polyurethane or silicone. The buffer layer 41 has a sealed receiving cavity 42, which allows the expansive fluid 43 to fill the receiving cavity 42 without leakage.

[0041] The expansive fluid 43 is a non-Newtonian fluid. The viscosity of the expansive fluid 43 increases with increasing shear rate. When the shear rate applied to the expansive fluid 43 increases, its viscosity increases significantly. Under a constant shear rate, the viscosity of the expansive fluid 43 does not change with time.

[0042] Please see Figure 1 When the user does not press button 1 or no object squeezes button 1, the button module is in the first state. The conductive spring 2 is not pressed by button 1, and the conductive spring 2 is spaced apart from the circuit board 3, so that the conductive spring 2 and the circuit board 3 are not conductive.

[0043] Please see Figure 2 When the user presses button 1 quickly, the button module is in the second state. The conductive spring 2 withstands the pressure of button 1 and generates a shear rate greater than or equal to the first rate. The viscosity of the expansive fluid 43 is greater than or equal to the first viscosity, causing the expansive fluid 43 to exhibit a solid-like state. The expansive fluid 43 and the buffer layer 41 can effectively support the circuit board 3 to remain fixed, causing the conductive spring 2 to deform in the direction away from button 1 and make contact with the conductive lines of the circuit board 3.

[0044] Please see Figure 3 When the user slowly presses button 1 or an object slowly squeezes button 1, the button module is in the third state. The conductive spring 2 is pressed by button 1 and generates a shear rate less than the first rate. The viscosity of the expansive fluid 43 is less than the first viscosity, so that the expansive fluid 43 exhibits a liquid-like state. The expansive fluid 43 and the buffer layer 41 deform together under the force transmitted from button 1. The circuit board 3 loses the support of the expansive fluid 43. The conductive spring 2 and the circuit board 3 deform together in the direction away from button 1, so that the conductive spring 2 and the conductive line of the circuit board 3 do not contact each other and the conductive spring 2 and the circuit board 3 are not conductive.

[0045] The viscosity of the expandable fluid 43 can be adjusted by changing the composition of the expandable fluid 43, so that the expandable fluid 43 can exhibit a solid-like state at a shear rate greater than or equal to the first rate, and a liquid-like state at a shear rate less than the first rate.

[0046] In this application, by setting the expandable fluid 43 and the conductive spring 2 at intervals along the first direction X, the expandable fluid 43 can exhibit a solid-like state at a shear rate greater than or equal to the first rate. The expandable fluid 43 supports the circuit board 3 and fixes it, so that the conductive spring 2 deforms away from the button 1 and makes contact with the conductive lines of the circuit board 3 to conduct electricity, thereby outputting an electrical signal for the user's operation of pressing the button 1 quickly; the expandable fluid 43 can also exhibit a liquid-like state at a shear rate less than the first rate. The expandable fluid 43, the buffer layer 41, the circuit board 3, and the conductive spring 2 deform together, so that the conductive spring 2 and the conductive lines of the circuit board 3 are not connected, so that the signal output of the button module is not affected by the user's slow pressing of the button 1 or the continuous pressure of the object on the button 1, reducing the false touch rate of the button module.

[0047] In one possible implementation, the button 1 includes a pressure point 11 and a conductive part 12 connected together. The conductive part 12 is disposed between the pressure point 11 and the conductive spring 2. The orthographic projection of the conductive part 12 along the first direction X onto the buffer layer 41 at least partially overlaps with the orthographic projection of the expansive fluid 43 along the first direction X onto the buffer layer 41.

[0048] The acupressure part 11 has a surface for contact with the user, who applies force to the button 1 by contacting this surface. The acupressure part 11 may be plate-shaped.

[0049] The conductive part 12 can be integrally formed with the acupressure part 11, or the conductive part 12 can be pre-prepared and then assembled onto the acupressure part 11. The conductive part 12 is used to transmit the force received by the acupressure part 11 to the conductive spring 2. The orthographic projection of the conductive part 12 along the first direction X onto the buffer layer 41 at least partially overlaps with the orthographic projection of the expansive fluid 43 along the first direction X onto the buffer layer 41, so that when the conductive part 12 rapidly presses the conductive spring 2, the conductive spring 2 can make stable contact with the portion of the circuit board 3 effectively supported by the expansive fluid 43.

[0050] Optionally, the orthographic projection of the conductive part 12 along the first direction X onto the buffer layer 41 is located within the orthographic projection of the expansive fluid 43 along the first direction X onto the buffer layer 41, so that the entire deformed conductive spring 2 is in stable contact with the portion of the circuit board 3 effectively supported by the expansive fluid 43.

[0051] The button 1 may include multiple conductive parts 12, which are connected to a finger pressure part 11. Each conductive part 12 corresponds to a different conductive spring 2, and each conductive spring 2 corresponds to a different conductive line on the circuit board 3. Thus, when the entire button 1 is pressed quickly, each conductive part 12 can deform its corresponding conductive spring 2, allowing each conductive spring 2 to contact a different conductive line on the circuit board 3. When a portion of the button 1 is pressed quickly, a single conductive part 12 can deform its corresponding conductive spring 2, allowing that single conductive spring 2 to contact its corresponding conductive line.

[0052] In one possible implementation, the buffer layer 41 includes at least two buffer sub-layers stacked along the first direction X, and one or more of the at least two buffer sub-layers form a receiving cavity 42.

[0053] The buffer layer 41 may have multiple buffer sublayers, and different buffer sublayers may be made of different materials so that the buffer layer 41 has different physical and chemical characteristics. The receiving cavity 42 may be formed by hollowing out one buffer sublayer or by hollowing out multiple buffer sublayers together.

[0054] In one possible implementation, at least two buffer sublayers include a first buffer sublayer 411 and a second buffer sublayer 412. The first buffer sublayer 411 includes a first buffer portion 4111 and a second buffer portion 4112 connected to each other. A receiving cavity 42 is formed in the first buffer portion 4111. The second buffer sublayer 412 is stacked on the side of the second buffer portion 4112 near the button 1.

[0055] The materials of the first buffer sublayer 411 and the second buffer sublayer 412 can be polyurethane prepared using different processes. Optionally, the rebound rate of the first buffer sublayer 411 is less than that of the second buffer sublayer 412, so that the first buffer sublayer 411 can adapt to deform along with the expandable fluid 43 in a liquid-like state, and after the pressure applied to the button 1 is removed, the first buffer sublayer 411 adapts to the expansionable fluid 43 switching from a liquid-like state to a solid-like state.

[0056] In one possible implementation, the second buffer portion 4112 is disposed around the first buffer portion 4111, and the second buffer sub-layer 412 is stacked on the side of the second buffer portion 4112 near the button 1, so that the compressed circuit board 3 can directly act on the first buffer sub-layer 411, and the part of the button 1 that does not contact the conductive spring 2 can directly act on the second buffer sub-layer 412.

[0057] In one possible implementation, the first buffer portion 4111 protrudes towards the button 1, the thickness of the first buffer portion 4111 along the first direction X is H1, and the thickness of the second buffer portion 4112 along the first direction X is H2, where H1 > H2.

[0058] The surface of the first buffer sub-layer 411 facing away from the button 1 can be flat, so that when the button module is installed in the electronic device, the first buffer sub-layer 411 can be supported on other structures of the electronic device. Other structures can be the mid-frame, motherboard, etc. of the electronic device.

[0059] The first buffer portion 4111 protrudes towards the button 1 relative to the surface of the second buffer portion 4112 near the button 1, and H1 > H2 is set to ensure that the first buffer portion 4111 has sufficient thickness to form the receiving cavity 42, and the sidewalls surrounding the receiving cavity 42 have sufficient thickness so that the first buffer portion 4111 can deform along with the expansive fluid 43, avoiding the first buffer portion 4111 from rupturing under pressure and causing the expansive fluid 43 to leak. The sufficient thickness of the sidewalls surrounding the receiving cavity 42 also allows the first buffer portion 4111 to recover its shape after the external force is removed, and the recovered shape of the first buffer portion 4111 drives the expansive fluid 43 in the receiving cavity 42 to recover its shape.

[0060] In one possible implementation, the button 1 further includes a locking part 13 connected to the acupressure part 11, and the buffer assembly 4 further includes a buckle 44 disposed on the buffer layer 41, with the locking part 13 engaging with the buckle 44.

[0061] The engaging part 13 engages with the latch 44 to ensure a stable connection between the button 1 and the buffer layer 41. When the button module is in the third state, the conductive spring 2 is pressed by the button 1 and generates a shear rate lower than the first rate. The viscosity of the expansive fluid 43 is lower than the first viscosity. The conductive spring 2 and the circuit board 3 deform together, and the engaging part 13 compresses the buffer layer 41, allowing the user to feel a damping sensation.

[0062] Please see Figure 4 This application provides a method for use in an electronic device, the electronic device having a button module as described above, the method comprising:

[0063] S100, if the button module outputs n first press signals within a first preset time period, calculate the interval between the first press signals with adjacent output times, where n≥2;

[0064] S200 determines whether to respond to n first press signals based on the duration of the first press signal and the interval duration.

[0065] Electronic devices can be mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, mobile internet devices (MID), augmented reality (AR) / virtual reality (VR) devices, robots, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc. They can also be servers, network attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. The embodiments in this application do not impose specific limitations.

[0066] The button module can serve as the input module of the entire device or as one of multiple input units within an input module. The input module can be a keyboard, screen-off control button, volume control button, brightness control button, etc. Multiple input units can be multiple buttons located on the keyboard. The circuit board of the button module is electrically connected to the processor of the electronic device. When the conductive contacts in the button module are electrically connected to the circuit board, the button module outputs changing electrical signals to the processor. These changing electrical signals include a first press signal and a second press signal. The first press signal and the second press signal can be a high-level signal and a low-level signal, respectively, in the output electrical signals.

[0067] Optionally, when the conductive spring in the button module is electrically connected to the conductive line of the circuit board, the button module outputs a low-level signal to the processor; when the conductive spring in the button module is disconnected from the conductive line of the circuit board, the button module outputs a high-level signal to the processor. If the user presses the button quickly three times, the conductive spring and the conductive line of the circuit board will sequentially connect and disconnect three times, causing the button module to output alternating low-level and high-level signals to the processor.

[0068] Optionally, when the conductive spring in the button module is electrically connected to the conductive line of the circuit board, the button module outputs a high-level signal to the processor; when the conductive spring in the button module is disconnected from the circuit board, the button module outputs a low-level signal to the processor. If the user presses the button quickly three times, the conductive spring and the conductive line of the circuit board will sequentially connect and disconnect three times, causing the button module to output alternating high-level and low-level signals to the processor.

[0069] The first preset duration and n value are pre-set values ​​to identify multiple button presses by the user within a short period of time. Optionally, the first preset duration is 3s to 4s, and n is 5.

[0070] When the first press signal is a high-level signal, n high-level signals are output sequentially in time. The n high-level signals are sorted according to their output time. The interval between the high-level signal at position P2 and the high-level signal at position P1 is calculated, the interval between the high-level signal at position P3 and the high-level signal at position P2 is calculated, and so on, until the interval between the high-level signal at position Pn-1 and the high-level signal at position Pn is calculated. This gives the interval between press signals with adjacent output times.

[0071] The duration of the first press signal and the interval between adjacent press signals reflect the duration and interval of the user's button press. If the interval is within a reasonable range, the button press is considered a genuine user intention; if the interval is too long or too short, the button press is considered a mis-press. Similarly, if the duration is within a reasonable range, the button press is considered a genuine user intention; if the duration is too long or too short, the button press is considered a mis-press.

[0072] In this application, by setting whether to respond to n first press signals based on the duration and interval of the first press signal, it is possible to determine whether the press signal is a false touch by outputting the interval and duration of the press signal, thereby reducing the false touch rate of the button module.

[0073] In one possible implementation, S200 includes:

[0074] S210, when the duration of m consecutive intervals is greater than the second preset duration, determine the adjacent first press signals that are calculated in pairs for the duration of m intervals, and calculate the average value based on the first press signal with the earlier output time among the adjacent first press signals, m≤n;

[0075] S220, responds to n first press signals when the average value is greater than or equal to a preset press threshold.

[0076] The m-value and preset press threshold are pre-set values ​​to identify the m rapid presses of the button module by the user within a short period of time. Optionally, m is 3. When the first press signal is a high-level signal, the preset press threshold is 270ms to 300ms. When the first press signal is a low-level signal, the preset press threshold is 200ms to 230ms.

[0077] For example, when the first press signal is a high-level signal, the preset press threshold is 280ms. The first press signals H1, H2, and H3 are output sequentially, T... H2-> T H1 ≤280ms, T H3-> T H2 ≤280ms, T H4-> T H3 If the time is ≤280ms, then the press input corresponding to the first press signals H1, H2, and H3 is considered as three rapid button presses. Calculate the average value of H1, H2, and H3, and compare this average value with a preset press threshold. If the average value is greater than or equal to the preset press threshold, respond to n first press signals; if the average value is less than the preset press threshold, do not respond to n first press signals.

[0078] When the button module is the power button, responding to n first press signals can trigger an emergency call.

[0079] In some embodiments, S220 includes:

[0080] S221, Detecting whether electronic devices are wearing protective cases;

[0081] S222, When the electronic device is not wearing a protective case, if the average value is greater than or equal to the first preset pressing threshold, it responds to n first pressing signals;

[0082] S223, When the electronic device is wearing a protective case, if the average value is greater than or equal to the second preset pressing threshold, it responds to n first pressing signals;

[0083] The first preset press threshold is set based on the duration of the press signal output by the button module when the electronic device is not wearing a protective case.

[0084] The second preset press threshold is set based on the duration of the press signal output by the button module when the electronic device is wearing a protective case, according to the user pressing the button module.

[0085] A protective case is a casing that is fitted over the outside of an electronic device to protect it from external damage. The casing can also have different patterns to enhance the appearance of the electronic device.

[0086] Because protective cases on electronic devices may partially obstruct buttons or hinder button presses to varying degrees, users' pressing habits differ depending on whether the device is protected or not. Users can pre-enter first and / or second preset button press thresholds based on their button press habits. Then, by determining whether the device is protected, the calculated average value is compared to the corresponding preset button press thresholds for that state, thereby improving the recognition of accidental touches and reducing the accidental touch rate.

[0087] In S221, a sensor installed on the electronic device can be used to detect whether the electronic device is wearing a protective case. The sensor can be a specific absorption rate sensor.

[0088] In some embodiments, prior to S220, the following is included:

[0089] Receive the first input;

[0090] Output the first prompt message, which is used to prompt the user to press the button module n times in succession when the electronic device is wearing a protective case;

[0091] Record n ​​third press signals output by the button module. The third press signals include low-level signals and high-level signals. Set the average value of the low-level signals or the average value of the high-level signals in the third press signals to a second preset press threshold.

[0092] Output a second prompt message, which prompts the user to press the button module n times consecutively when the electronic device is not wearing a protective case.

[0093] Record n ​​fourth press signals output by the button module. The fourth press signals include low-level signals and high-level signals. Set the average value of the low-level signals or the average value of the high-level signals in the fourth press signals to a second preset press threshold.

[0094] The first and second prompts can be text or image information displayed on a screen, or they can be voice information played through a speaker, vibration information output by a vibration module, etc.

[0095] It should be noted that the key signal recognition method provided in this application embodiment can be executed by a key signal recognition device. This application embodiment uses a key signal recognition device executing the key signal recognition method as an example to illustrate the key signal recognition device provided in this application embodiment.

[0096] Figure 5This is a schematic diagram of the structure of a key signal recognition device provided in another embodiment of this application, as shown below. Figure 5 As shown, the device for recognizing the key signal may include:

[0097] As mentioned above, button module 501;

[0098] The calculation module 502 is used to calculate the interval between the first press signals with adjacent output times when the button module 501 outputs n first press signals within a first preset time period, where n≥2;

[0099] The response module 503 is used to determine whether to respond to n first press signals based on the duration of the first press signal and the interval duration.

[0100] In an optional example, response module 503 includes:

[0101] The first calculation unit is used to determine adjacent first press signals that are paired and calculated for m consecutive intervals when the duration of each interval is greater than the second preset duration, and to calculate the average value of the first press signal with the earlier output time among the adjacent first press signals, where m≤n;

[0102] The first response unit is used to respond to n first press signals when the average value is greater than or equal to a preset press threshold.

[0103] In another optional example, the first response unit is also used for:
