Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a button and a wearable device. Background Technology

[0002] With the rapid advancement of information technology and people's increasing demands for portability and intelligence in wearable devices such as smartwatches, miniaturization, lightweight design, high screen-to-body ratio, and high interactivity are the future development directions for smartwatches. In practical applications of smartwatches, touchscreen displays are typically integrated to enhance the human-computer interaction experience. However, when users directly operate the touchscreen with their fingers, its small size can easily lead to partial obstruction of the display area, preventing users from clearly viewing the obscured portion and thus reducing the overall human-computer interaction experience. Utility Model Content

[0003] This application provides a button and a wearable device, which allows users to interact with the wearable device through the button, thus avoiding the problem that some display areas are obstructed when the touch screen of the wearable device is directly operated by the finger, which affects the user experience.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] Firstly, a button is provided for use in wearable devices. The button includes: a keycap, a pressure-sensitive trigger component, and a physical button conduction component. The physical button conduction component is disposed at the bottom of the keycap, and the pressure-sensitive trigger component is disposed between the keycap and the physical button conduction component. The pressure-sensitive trigger component is used to realize pressure-sensitive touch control, and the physical button conduction component is used to realize physical press control. When the keycap is subjected to a force less than or equal to a first threshold, the keycap can drive the pressure-sensitive trigger component to be triggered, and the physical button conduction component is not activated. When the keycap is subjected to a force greater than the first threshold, the keycap can drive the physical button conduction component to be activated, and the pressure-sensitive trigger component is not triggered.

[0006] The button provided in this application embodiment allows users to control the touch screen display by operating the button, without having to directly operate the touch screen with their fingers. This avoids the touch screen display area being blocked by fingers, allowing users to intuitively view the entire display area of ​​the touch screen, thereby improving the human-computer interaction experience.

[0007] In addition, with the buttons provided in this application embodiment, users only need to press to control different operations and functions of the buttons. When performing different functions, only the pressure of pressing the button needs to be adjusted, without the need for additional operations. Therefore, it can improve operating efficiency and enhance user experience.

[0008] In some embodiments, the keycap includes a key axis, which is an integral part of the keycap. The key axis is disposed between the keycap and the pressure-sensitive trigger component and is capable of transmitting pressure from the keycap to the pressure-sensitive trigger component and the physical key conduction component.

[0009] In this embodiment, the key shaft includes a first part and a second part. The first part is disposed on one side of the pressure-sensitive steel sheet and is used to transmit pressure from the keycap to that side; the second part is disposed on the other side of the pressure-sensitive steel sheet and is used to transmit pressure from the keycap to that side. This arrangement allows the first part and the second part to transmit different proportions of pressure to the pressure-sensitive steel sheet.

[0010] In some embodiments, the pressure-sensitive triggering component includes: a pressure-sensitive steel sheet disposed on the side near the keycap, the pressure-sensitive steel sheet including a support component disposed on the side of the pressure-sensitive steel sheet away from the keycap, wherein when the keycap is subjected to force, the keycap can drive the pressure-sensitive steel sheet to bend and deform relative to the support component; a pressure-sensitive sensor disposed between the keycap and the pressure-sensitive steel sheet, used to detect the force and the position of the force on the pressure-sensitive steel sheet based on the bending deformation of the pressure-sensitive steel sheet, and convert the force into a change in resistance and send it to the smartwatch to realize the pressure-sensitive touch control; and also used to stop working when the force on the pressure-sensitive steel sheet is detected to be greater than a first threshold; the physical key conduction component includes: a dome component disposed on the side of the pressure-sensitive steel sheet away from the keycap, used to be triggered when the force on the pressure-sensitive steel sheet is greater than the first threshold to realize physical press control.

[0011] In some embodiments, the key shaft is disposed between the keycap and the pressure-sensitive steel sheet and is fixedly connected to the pressure-sensitive steel sheet, and is capable of transmitting pressure from the keycap to the pressure-sensitive steel sheet.

[0012] In some embodiments, the wearable device includes a housing with a mounting groove, and at least a portion of the components of the button are disposed in the mounting groove; the button also includes a limiting component disposed on the side of the pressure-sensitive steel sheet near the keycap, for limiting the distance between the pressure-sensitive steel sheet and the keycap; the keycap, the key shaft, and the pressure-sensitive steel sheet form an accommodating space, and the limiting component, the pressure-sensitive sensor, and a portion of the housing structure are all disposed in the accommodating space.

[0013] In some embodiments, within the receiving space, the keycap and a portion of the housing structure are connected by a compression spring having a first compression amount, under which the stiffness of the compression spring is less than the stiffness of the pressure-sensitive steel sheet.

[0014] In this embodiment, the keycap and part of the housing are connected by a compression spring so that the key and the housing maintain stable contact and do not wobble.

[0015] In some embodiments, the button further includes a waterproof interface that fills the gap between the button and the housing.

[0016] By setting a waterproof interface, the pressure-sensitive sensor inside the button and the circuitry connecting to the smartwatch can be protected against water, dust, and dirt.

[0017] In some embodiments, the support assembly is positioned at the center of the pressure-sensitive steel sheet; the dome assembly is connected to the support assembly and has a first gap between it and the housing located at the bottom of the support assembly; or, the dome assembly is fixedly connected to the housing located at the bottom of the support assembly and has a second gap between it and the support assembly, wherein the widths of the first gap and the second gap are the same or different.

[0018] In some embodiments, the first gap includes any value between 0.3 and 0.7 mm; the second gap includes any value between 0.3 and 0.7 mm.

[0019] In some embodiments, the button further includes an ECG conducting steel sheet, which is disposed on the support assembly to enable the ECG conducting function of the button.

[0020] In this embodiment, by designing the ECG conductive steel sheet on the support component of the pressure-sensitive steel sheet, it is ensured that the proportional relationship between the pressure applied to the pressure-sensitive steel sheet by the first part and the second part of the button shaft is not affected, thus ensuring that the conductive steel sheet does not affect the sliding recognition process.

[0021] In some embodiments, a portion of the housing structure located in the receiving space has a groove on the side near the pressure-sensitive steel sheet. The groove is used to receive a limiting component, and an elastic body is disposed between the limiting component and the bottom of the groove. The elastic body has a second compression amount. Under the second compression amount, one side interface of the elastic body contacts the bottom of the groove, and the other side interface contacts the limiting component.

[0022] This configuration breaks down the fixed constraint of the pressure-sensitive steel sheet by the support component into the hinge constraint of the contact surface between the dome component and the support component and the angle constraint of the limiting component, thus preventing the pressure-sensitive steel sheet from tilting during the pressing process and improving the sensitivity of the deformation structure.

[0023] In some embodiments, the key further includes: a clamping structure disposed on the side of the pressure-sensitive steel sheet away from the keycap, used to replace the support component, wherein when the keycap is subjected to force, the keycap can drive the pressure-sensitive steel sheet to bend relative to the clamping structure; wherein the key shaft includes a first part and a second part, the first part being disposed on one side of the pressure-sensitive steel sheet; the second part being disposed on the other side of the pressure-sensitive steel sheet; the physical key conduction component includes: a first dome component and a second dome component, the first dome component being disposed on the side of the pressure-sensitive steel sheet away from the keycap and corresponding to the position of the first part, the second dome component being disposed on the side of the pressure-sensitive steel sheet away from the keycap and corresponding to the position of the second part; the key further includes: a first elastic support pillar disposed between the first dome component and the pressure-sensitive steel sheet and corresponding to the position of the first part; the second elastic support pillar being disposed between the second dome component and the pressure-sensitive steel sheet and corresponding to the position of the second part.

[0024] In some embodiments, the button further includes an ECG conducting steel sheet, which is disposed on the first elastic support or the second elastic support to enable the button's ECG conducting function.

[0025] In some embodiments, the button further includes a floating column, one end of which is connected to the keycap, and the other end of which passes through the pressure-sensitive trigger component and is connected to the physical key conduction component, for transmitting pressure from the keycap to the physical key conduction component.

[0026] In this embodiment, by setting a floating column, the triggering path of the physical key conduction component is decoupled from that of the pressure-sensitive triggering component. The pressure-sensitive steel sheet and the housing are fixedly connected by adhesive or screw fastening. This can reduce the impact of errors caused by design and manufacturing consistency on the pressure-sensitive system, reduce the tolerance requirements for key gap control, and improve the manufacturability of the solution.

[0027] In a second aspect, a wearable device is provided, including a housing and a button as shown in the first aspect, the housing having a mounting slot, and at least a portion of the button components being disposed within the mounting slot.

[0028] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0044] The technical solutions provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0045] It should be understood that in the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0046] In this embodiment, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0047] With the rapid advancement of information technology and people's increasing demands for portability and intelligence in wearable devices such as smartwatches, miniaturization, lightweight design, high screen-to-body ratio, and high interactivity are the future development directions for smartwatches. In practical applications of smartwatches, to better enhance the human-computer interaction experience, smartwatches typically integrate a touchscreen display, allowing users to interact with the smartwatch through this display. However, when users directly operate the touchscreen with their fingers, the small size of the display may cause parts of the screen to be obstructed, making it difficult for users to see the obscured portion.

[0048] To enhance the human-computer interaction experience, smartwatches typically feature at least one button (such as a crown) that allows users to operate the watch. See also Figure 1A The diagram shows a schematic of a smartwatch according to an embodiment of this application. As shown, the smartwatch includes a button, i.e., a crown, which is approximately located on the outer side of the three o'clock position. Users can rotate the crown clockwise or counterclockwise to slide the content displayed on the touchscreen. See also... Figure 1B The figure shows a schematic diagram of the structure of a smartwatch provided in another embodiment of this application. As shown in the figure, the smartwatch includes two independent buttons, namely the up button and the down button, which are located at the top and bottom ends of the outside of the smartwatch, respectively. Users can press the two independent buttons to slide the content displayed on the touch screen up and down.

[0049] In some implementations, users can also interact with the smartwatch via virtual buttons integrated on the touchscreen, such as swiping up and down on the touchscreen with their fingers. (See [link to relevant documentation]). Figure 1C As shown in the image.

[0050] However, using the existing buttons on a smartwatch to perform some functions results in low operational efficiency and a poor user experience.

[0051] For example, in scenarios where users interact with a smartwatch via the crown, rotating the crown requires a circular button of a certain diameter for operation. Simultaneously, the speed and direction of the crown's rotation should be identified using methods such as light or magnetism to enable continuous, variable-speed up-and-down scrolling of content on the touchscreen. Confirmation is then achieved by pressing the crown. In other words, the process of sliding and confirming using the crown involves rotating it for up-and-down scrolling and pressing it for confirmation. Clearly, different functions require different actions, reducing operational efficiency and resulting in a poor user experience.

[0052] Furthermore, in actual use, users need to rotate the corresponding modules with their fingers, so there are certain requirements for the design of the crown. For example, if the diameter of the crown is too small, it will be difficult to rotate, increasing the difficulty of operation. However, on small smartwatches or smart bracelets, if the diameter of the crown is too large, exceeding the thickness of the entire device, the crown will be too close to the skin to rotate or will look out of place.

[0053] In summary, during the human-computer interaction process with a smartwatch via the crown, not only is there low operational efficiency and a poor user experience when performing certain functions, but it also places higher demands on the design of the crown size.

[0054] For example, in scenarios where users interact with a smartwatch via buttons, the up and down buttons can be used to switch between individual pages, or a long press can be used for continuous switching, with confirmation achieved via the touchscreen. For instance, pressing the up button flips from the previous page to the next; pressing the down button flips from the current page to the next; and a long press flips through multiple pages. It's clear that button interaction meets the needs of small smartwatches or smart bracelets, but it's inefficient and cannot achieve rapid, continuous page navigation. Furthermore, if blind operation requiring swiping and confirmation is needed, a third button is required to assist with the confirmation process.

[0055] Therefore, the process of interacting with a smartwatch using the up and down buttons also suffers from low operating efficiency and a poor user experience.

[0056] For example, in scenarios where human-computer interaction with a smartwatch is achieved through virtual buttons, users can trigger corresponding operations by touching or clicking virtual buttons on the touchscreen. For instance, users can perform touch operations such as swiping up and down on the touchscreen to achieve the corresponding function. However, virtual button operations are typically based on magnetic, capacitive, or piezoresistive methods and are active buttons. The signals they generate need to be processed before they can be interpreted as actual actions. Therefore, in the event of device malfunction (such as a program error), virtual buttons cannot perform operations such as error recovery on their own; they need to be used in conjunction with physical buttons on the smartwatch to achieve functions such as device restart. Therefore, human-computer interaction via virtual buttons also suffers from low operational efficiency and a poor user experience.

[0057] To address this issue, this application provides a button and a wearable device. Users can interact with the wearable device via the button, avoiding the problem that when directly operating the touch screen of the wearable device with fingers, the touch screen may be partially blocked by fingers due to its small size, making it impossible for users to intuitively view the obscured display area and thus reducing the human-computer interaction experience.

[0058] In addition, the button can perform touch operations such as clicking and sliding of virtual buttons through the pressure-sensitive trigger component, and can also perform the functions of physical buttons through the physical button conduction component, realizing the compatibility of pressure-sensitive touch and physical buttons. When the button provided in this application embodiment interacts with wearable devices, the user only needs to apply different pressure to achieve different operations and functions, and there is no need to switch actions during the operation, thereby improving the operation efficiency of the button.

[0059] It should be noted that the buttons provided in this application embodiment can be applied not only to wearable devices with small touchscreen displays, but also to other terminal devices such as mobile phones, tablets, and laptops. Specific applications can be configured according to the usage requirements of the device, and this embodiment does not impose any limitations on this. The following will use the application of buttons in a wearable device, specifically a smartwatch, as an example to explain the button structure provided in this application embodiment.

[0060] Figure 2 This is a schematic diagram of the structure of a button provided in one embodiment of this application, as shown below. Figure 2As shown, the button 100 provided in this embodiment includes a keycap 101, a pressure-sensitive trigger component 102, and a physical key conduction component 103. The physical key conduction component 103 is disposed at the bottom of the keycap 101, and the pressure-sensitive trigger component 102 is disposed between the keycap 101 and the physical key conduction component 103. The pressure-sensitive trigger component 102 is used to implement pressure-sensitive touch control, and the physical key conduction component 103 is used to implement physical press control. When the keycap 101 is subjected to a force less than or equal to a first threshold, the keycap 101 can drive the pressure-sensitive trigger component 102 to be triggered, and the physical key conduction component 103 is not activated. When the keycap 101 is subjected to a force greater than the first threshold, the keycap 101 can drive the physical key conduction component 103 to be activated, and the pressure-sensitive trigger component 102 is not triggered.

[0061] Pressure-sensitive touch control involves detecting the force exerted by the user pressing the keycap 101, i.e., the force applied by the user to the keycap 101, and triggering different operations or functions based on different pressure levels. In this embodiment, when the user applies a force less than or equal to a first threshold to the keycap 101, the pressure-sensitive trigger component 102 can recognize touch operations of different strengths, such as light touch, medium press, and heavy press, and provide different responses according to the magnitude of the force, such as light press preview, swipe preview, and heavy press to open, thereby providing users with more operation options and improving the operating efficiency and experience of the device. Specific application scenarios can include terminal devices such as smartphones, smartwatches, and laptop touchpads.

[0062] In some embodiments, pressure-sensitive touch is achieved using capacitive or piezoelectric sensors. Capacitive or piezoelectric sensors can detect minute deformations or pressure changes during touch and convert them into electrical signals that are transmitted to the terminal device. The terminal device determines the user's pressure level based on the signal strength, thereby enabling corresponding operations and functions.

[0063] Physical press control is a control technology that uses physical pressure to control the corresponding operations and functions of physical buttons. Physical press control requires the user to apply a certain amount of pressure to trigger the operation and function. Optionally, a pressure sensor or mechanical switch can be used to detect the user's pressing action. In this embodiment, when the user applies a force greater than a first threshold to the keycap 101, the physical key conduction component 103 is triggered to achieve the corresponding function, such as returning, powering off, or forced restarting.

[0064] In some embodiments, a first gap exists between the pressure-sensitive trigger component 102 and the physical key conduction component 103. When the force applied to the keycap 101 is less than or equal to a first threshold, the keycap 101 can drive the pressure-sensitive trigger component 102 to travel a first distance in the direction of the force. Since the force is less than or equal to the first threshold, the first distance may be less than or equal to the width of the first gap, so that when the pressure-sensitive trigger component 102 is triggered, the physical key conduction component 103 is not activated. When the force applied to the keycap 101 is greater than the first threshold, the keycap 101 drives the pressure-sensitive trigger component 102 to travel a second distance in the direction of the force. Since the force is greater than the first threshold, the second distance may be greater than the width of the first gap, thereby triggering the physical key conduction component 103 to activate. At this time, since the force applied to the keycap is large and exceeds the triggering range of the pressure-sensitive trigger component 102, the pressure-sensitive trigger component 102 stops working, i.e., is disabled, so that the pressure-sensitive trigger component is not triggered.

[0065] By applying the button 100 provided in this application embodiment to a smartwatch, users can interact with the smartwatch 200 through the button 100, which avoids the problem that some display areas are obstructed when directly operating the touch screen of the smartwatch 200 with fingers, thus affecting the user experience.

[0066] Furthermore, the button 100 provided in this embodiment is compatible with both physical and virtual button functions. During human-computer interaction with a smartwatch using the button 100, since it incorporates both a pressure-sensitive trigger component 102 and a physical button conduction component 103, it can achieve both pressure-sensitive touch control and physical press control. Users only need to apply different pressure levels to achieve different operations and functions, and no switching action is required during operation, thereby improving the operational efficiency of the button 100. Simultaneously, the button provided in this embodiment is compatible with physical button functions, solving the problem that existing virtual buttons cannot perform a hard reset when the device malfunctions during application.

[0067] The following explanation further illustrates the buttons provided in the embodiments of this application, taking into account their specific applications in smartwatches.

[0068] Figure 3 This is a schematic diagram of the structure of a button provided in one embodiment of this application, as shown below. Figure 3 As shown, the button 100 includes a keycap 101, a pressure-sensitive trigger component 102, and a physical key conduction component 103.

[0069] The pressure-sensitive triggering component 102 includes: a pressure-sensitive steel sheet 1021, which is disposed on the side near the keycap 101. The pressure-sensitive steel sheet 1021 includes a support component 10211, which is disposed on the side of the pressure-sensitive steel sheet 1021 away from the keycap 101. When the keycap 101 is subjected to force, the keycap 101 can drive the pressure-sensitive steel sheet 1021 to bend and deform relative to the support component 10211; and a pressure-sensitive sensor 1022, which is disposed between the keycap 101 and the pressure-sensitive steel sheet 1021, and moves with the pressure-sensitive steel sheet 1021. The bending deformation of the pressure-sensitive steel sheet 1021 is used to detect the force and location of the force on the pressure-sensitive steel sheet 1021 based on the bending deformation, and converts the force into a change in resistance and sends it to the smartwatch 200 to achieve pressure-sensitive touch control; it is also used to stop signal transmission when the force on the pressure-sensitive steel sheet 1021 is detected to be greater than a first threshold; the ECG conducting steel sheet 1023 is set at the bottom of the pressure-sensitive steel sheet 1021 and is used to provide the ECG signal detection path for the keycap 101, the pressure-sensitive steel sheet 1021, the ECG conducting steel sheet 1023, and the entire circuit board.

[0070] The physical key activation component 103 includes a dome component 1031, which is located on the side of the pressure-sensitive steel plate 1021 away from the keycap 101. It is triggered when the force applied to the pressure-sensitive steel plate 1021 exceeds a first threshold, thereby achieving physical press control. The dome component 1031 cannot connect to the circuit when not triggered; after being pressed, the circuit is activated, providing a signal to the smartwatch 200 circuitry.

[0071] In this embodiment, the keycap 101 includes a key shaft 1011, which is an integral structure with the keycap 101. The key shaft 1011 is disposed between the keycap 101 and the pressure-sensitive trigger assembly 102, specifically, between the keycap 101 and the pressure-sensitive steel sheet 1021, and is fixedly connected to the pressure-sensitive steel sheet 1021, and can transmit pressure from the keycap 101 to the pressure-sensitive trigger assembly 102, i.e., the pressure-sensitive steel sheet 1021, and the physical key conduction assembly 103, i.e., the dome assembly 1031.

[0072] The key shaft 1011 provided in this embodiment includes a first part 10111 and a second part 10112. The first part 10111 is disposed on one side of the pressure-sensitive steel sheet 1021 and is used to transmit pressure from the keycap 101 to that side; the second part 10112 is disposed on the other side of the pressure-sensitive steel sheet 1021 and is used to transmit pressure from the keycap 101 to that side.

[0073] The smartwatch 200 to which the button 100 provided in this embodiment is applied includes a housing 201, which has a mounting groove, and at least a portion of the components of the button 100 are disposed within the mounting groove. Figure 3As shown, the button 100 also includes a limiting component 105, which is disposed on the side of the pressure-sensitive steel sheet 1021 near the keycap 101. This limiting component 105 limits the distance between the pressure-sensitive steel sheet 1021 and the keycap 101, thereby preventing the pressure-sensitive steel sheet 1021 from tilting during pressing and improving the sensitivity of the deformable structure. The keycap 101, the key shaft 1011 (including a first part 10111 and a second part 10112), and the pressure-sensitive steel sheet 1021 form a receiving space. The limiting component 105, the pressure-sensitive sensor 1022, and parts of the housing 201 are all disposed within this receiving space.

[0074] It should be understood that the housing 201 of the smartwatch 200 involved in this application embodiment refers to the outer frame or outer shell of the smartwatch 200, which encloses and protects the internal components of the smartwatch 200, such as the display screen, battery, and processor. When some components of the button 100 are connected to the housing 201, they can be in a stable state relative to the housing 201. The specific structure of the housing 201 is adapted to the composition structure of the button 100.

[0075] In this embodiment, within the accommodating space formed by the keycap 101, the key shaft 1011, and the pressure-sensitive steel sheet 1021, a portion of the keycap 101 and the housing 201 are connected by a compression spring 104, ensuring stable contact between the keycap 100 and the housing 201 without any shaking. This arrangement is independent of the position of the compression steel sheet 1021; it only requires that one end of the sheet is connected to the keycap 101 and the other end to the housing 201.

[0076] In this embodiment, the compression spring 104 has a first compression amount. Under this first compression amount, the stiffness of the compression spring 104 is less than the stiffness of the pressure-sensitive steel sheet 1021, thereby reducing the minimum trigger threshold of the pressure-sensitive touch.

[0077] In this embodiment, the button 100 also includes a waterproof interface 106, which fills the gap between the button 100 and the housing 201, ensuring the waterproof performance of the pressure-sensitive sensor 1022 inside the button 100 and the circuit connected to the smartwatch 200.

[0078] In this embodiment, the support component 10211 is positioned in the center of the pressure-sensitive steel sheet 1021. When the user applies a certain pressure at different positions on the keycap 101, different proportions of pressure are transmitted to the pressure-sensitive steel sheet 1021 through the key shafts 1011 at both ends of the key 100, which allows the pressure-sensitive steel sheet 1021 to undergo corresponding bending deformation at both ends of the support component 10211.

[0079] It should be noted that the centering position involved in this embodiment includes the center position of the pressure-sensitive steel sheet 1021 and the preset area near the center position. The position within the preset area can be considered as the centering position of the pressure-sensitive steel sheet 1021.

[0080] In one implementation of this embodiment, the dome component 1031 is connected to the support component 10211 and has a first gap between itself and the housing 201 located at the bottom of the support component 10211; alternatively, the dome component 1031 is fixedly connected to the housing 201 located at the bottom of the support component 10211 and has a second gap between itself and the support component 10211, wherein the widths of the first gap and the second gap are the same or different. For example, the first gap includes any value between 0.3 and 0.7 mm; the second gap includes any value between 0.3 and 0.7 mm. In this embodiment, the button travel of the dome component 1031 is provided by either the first gap between the dome component 1031 and the housing 201 located at the bottom of the support component 10211, or the second gap between the dome component 1031 and the support component 10211.

[0081] In this embodiment, the ECG conductive steel sheet 1023 is disposed on the support assembly 10211. By designing the ECG conductive steel sheet 1023 on the support assembly 10211 of the pressure-sensitive steel sheet 1021, it does not affect the proportional relationship between the pressure applied to the pressure-sensitive steel sheet 1021 by the first part 10111 and the second part 10112 in the key shaft 1011, thus ensuring that the ECG conductive steel sheet 1023 does not affect the sliding recognition process.

[0082] The operating principle of the button 100 provided in this embodiment will be explained below.

[0083] When a user applies a certain amount of pressure to different positions on the keycap 101, different proportions of pressure can be transmitted through the key shafts 1011 at both ends of the keycap 101, namely the first part 10111 and the second part 10112 of the key shaft 1011. See [link / reference] Figure 4 As shown, this results in different deformations of the pressure-sensitive steel sheets 1021 at the left and right ends. See also Figure 5As shown, at position X = -5mm, the user applies pressure f to keycap 101. According to mechanical balance, the force f1 on the left side of pressure-sensitive steel sheet 1021 is greater than the force f2 on the right side, resulting in a larger deformation 1 on the left side of pressure-sensitive steel sheet 1021. Different deformation amounts will produce different resistance changes. When pressure sensor 1022 detects the forces on both sides of pressure-sensitive steel sheet 1021, it converts the force into a resistance change and sends it to the electrical signal calculation module in smartwatch 200. The electrical signal calculation module identifies the voltage signal based on the resistance change, thereby calculating the user's pressing position. Finally, based on the position and magnitude of the force identified at different time points, pressure-sensitive touch can be triggered and the touch screen can be driven to slide at different speeds.

[0084] Optionally, the electrical signal processing module can be a microcontroller unit (MCU) or an analog front-end (AFE).

[0085] See Figure 6 The diagram shown is a schematic representation of the structure of a button before and after being pressed, according to an embodiment of this application. Figure 6 As shown, when the user actually presses the keycap 101, if the force F applied by the user to the keycap 101 is less than F1, the pressure-sensitive steel sheet 1021 comes into contact with the dome component 1031. At this time, the dome component 1031 provides a steel sheet support point for the pressure-sensitive steel sheet 1021, which is used to provide the reaction force and torque required for the bending deformation of the pressure-sensitive steel sheet 1021.

[0086] When the force F applied by the user is greater than F1, the pressure sensor 1022 can determine the magnitude and position of the applied force based on the force F, convert the force into a change in resistance, and send it to the electrical signal calculation module in the smartwatch 200. The electrical signal calculation module responds to the signal, that is, it identifies the voltage signal based on the change in resistance, and then calculates the user's pressing position. Finally, based on the position and magnitude identified at different time points, the pressure-sensitive touch can be triggered and the screen can be driven to slide at different speeds. Since the force applied by the user is insufficient to trigger the dome component 1031, the pressure-sensitive touch is turned on, and the physical pressing control is not turned on.

[0087] When the force F applied by the user exceeds F2, the dome component 1031 is triggered, sending high and low level signals to the smartwatch 200. This can be used for system malfunction recovery. In this case, physical press control is activated, and the pressure sensor 1022 stops working, i.e., it stops sending signals to the smartwatch 200, and pressure-sensitive touch operation is not triggered. The interaction process of the button 100 and various components in the smartwatch 200 can be found in [reference needed]. Figure 7 As shown in the image.

[0088] This application provides a button 100 that is compatible with both physical button control and pressure-sensitive touch operation. It can provide interaction methods such as light press, long press, hard press and swipe, thus realizing the ease of use of the button 100. At the same time, it provides the ECG function of the button 100 and the whole machine abnormal recovery path.

[0089] Figure 8 A schematic diagram of the button structure provided in another embodiment of this application. See also... Figure 8 As shown in the diagram, in this embodiment, a portion of the housing 201 within the accommodating space formed by the keycap 101, key shaft 1011, and pressure-sensitive steel sheet 1021 has a groove 2011 on the side near the pressure-sensitive steel sheet 1021. This groove 2011 is used to accommodate a limiting component 105, and the side of the limiting component 105 near the groove 2011 contacts the bottom of the groove 2011. The groove 2011 is positioned corresponding to the fulcrum at the center of the pressure-sensitive steel sheet 1021.

[0090] In this embodiment, the button 100 also includes a pressing structure 2012, which is disposed on the side of the pressure-sensitive steel sheet 1021 away from the limiting component 105, and its position corresponds to the fulcrum at the center of the pressure-sensitive steel sheet 1021.

[0091] In addition, the physical key conduction component 103 in this embodiment includes a first dome component 10311 and a second dome component 10312. The first dome component 10311 is positioned to correspond to the position of the first part 10111, and the second dome component 10312 is positioned to correspond to the position of the second part 10112. Pressure from the keycap 101 is transmitted to the first dome component 10311 through the first part 10111 and the first elastic support 10212, and pressure from the keycap 101 is transmitted to the second dome component 10312 through the second part 10112 and the second elastic support 10213.

[0092] In this embodiment, the ECG conductive steel sheet can be disposed on the first elastic support 10212 or on the second elastic support 10213.

[0093] In this configuration, the original support component 10211, which was originally located in the center of the pressure-sensitive steel sheet 1021 on the side away from the keycap 101, can be removed. The pressure-sensitive steel sheet 1021 is supported by the clamping structure 2012. The gap between the pressure-sensitive steel sheet 1021 and the first dome component 10311 is filled by the first elastic support 10212, and the gap between the pressure-sensitive steel sheet 1021 and the second dome component 10312 is filled by the second elastic support 10213.

[0094] The first dome component 10311 implements a first physical key activation function, and the second dome component 10312 implements a second physical key activation function. The first and second physical key activation functions can be the same or different. When the first and second physical key activation functions are the same, the problem of the central single dome component not being triggered due to pressing one end of the button 100 can be avoided. When the first and second physical key activation functions are different, different physical key activation functions can be implemented when pressing the button 100 at different positions. For example, pressing... Figure 8 The left side of the screen triggers functions such as returning; press... Figure 8 When the device is positioned to the right as shown in the diagram, functions such as power on / off are triggered.

[0095] In this embodiment, the limiting component 105 is adjusted inside the housing 201 and fixed by the bottom clamping structure 2012, achieving rigid constraint at the central fulcrum position of the pressure-sensitive steel sheet 1021. This avoids vertical displacement or rotation of the fulcrum during the pressing process, improving the sensitivity of the deformable structure. Two dome components 1031 for triggering the physical button function are positioned at corresponding positions in the first part 10111 and the second part 10112. This not only increases the physical button function but also avoids the problem that pressing one end of the button 100 will not trigger the central single dome component 1031.

[0096] The button 100 structure provided in this application embodiment can avoid the rotation of the central fulcrum during the pressing of the button 100, reduce component noise, improve the manufacturability of the solution, and avoid the problem that the central single dome component 1031 cannot be triggered due to pressing one end of the button 100, thus improving the design experience.

[0097] Figure 9 A schematic diagram of the button structure provided in another embodiment of this application. See also... Figure 9 As shown in the figure, in this embodiment, a portion of the structure of the housing 201 located in the accommodating space formed by the keycap 101, the key shaft 1011, and the pressure-sensitive steel sheet 1021 has a groove 2011 on the side near the pressure-sensitive steel sheet 1021. The groove 2011 is used to accommodate the limiting component 105, and an elastic body 107 is provided between the limiting component 105 and the bottom of the groove 2011. The elastic body 107 has a second compression amount. Under the second compression amount, one side interface of the elastic body 107 contacts the bottom of the groove 2011, and the other side interface contacts the limiting component 105.

[0098] Optionally, the elastomer 107 can be a spring or soft silicone.

[0099] This configuration allows the fixing constraint of the pressure-sensitive steel sheet 1021 by the support component 10211 to be decomposed into the hinge constraint of the contact surface between the dome component and the support component 10211, and the angular constraint of the limiting component 105. Compared to the solution where the torque required for the bending deformation of the pressure-sensitive steel sheet 1021 is provided only by the contact surface between the dome component 1031 and the bottom support component 10211 of the pressure-sensitive steel sheet 1021, due to the miniaturization requirements of wearable devices, this contact surface may be small (e.g., it may be a circle with a diameter of 0.8 mm), and may not be able to provide sufficient torque support in practical applications. This solution avoids the tilting of the pressure-sensitive steel sheet 1021 during the pressing process, improving the sensitivity of the deformation structure.

[0100] During actual pressing, when the force F applied by the user is less than F1, the button 100 will not respond. F1 consists of two parts: F11 is the contact stress at which the interface between the limiting component 105 and the pressure-sensitive steel sheet 1021 separates after pressing; F12 is the rebound force of the compression spring 104 that must be overcome to allow the pressure-sensitive steel sheet 1021 to contact the dome component 1031 via the support component 10211. To minimize the range of F1, in this embodiment, an elastic body 107 is provided between the limiting component 105 and the bottom of the groove 2011. This elastic body 107 is connected to the housing 201 and designed with sufficient compression (e.g., 0.5mm) to ensure that during pressing, one side of the elastic body 107 contacts the bottom of the groove 2011, and the other side contacts the limiting component 105, preventing separation of the two pressing interfaces and avoiding the generation of contact stress F11. Figure 10 As shown, the existence of the first region ① is avoided, thereby increasing the minimum detection threshold of the sliding button.

[0101] By setting the button 100 in this embodiment and adjusting the support method of the pressure-sensitive steel sheet 1021, the contact separation process during use is eliminated, the sensitivity of the sliding button 100 under the same force is improved, and more precise position discrimination can be achieved; by removing the influence of contact stress F11, the minimum trigger threshold for sliding is reduced, and the sensitivity of operation is improved.

[0102] Figure 11 See also the schematic diagram of the button structure provided in another embodiment of this application. Figure 11 As shown, the button 100 includes a keycap 101, a pressure-sensitive trigger component 102, and a physical key conduction component 103. The button 100 also includes a floating column 108, one end of which is connected to the keycap 101, and the other end passes through the pressure-sensitive trigger component 102 and is connected to the physical key conduction component, for transmitting pressure from the keycap 101 to the physical key conduction component.

[0103] The pressure-sensitive triggering component 102 includes a first pressure-sensitive triggering component 1024 and a second pressure-sensitive triggering component 1025 respectively disposed on both sides of the suspension column 108 and communicating with each other. The keycap 101 includes a key shaft 1011, which is an integral structure with the keycap 101. The key shaft includes a first part 10111 and a second part 10111. The first part 10111 is disposed between the keycap 101 and the first pressure-sensitive triggering component 1024 and can transmit pressure from the keycap 101 to the first pressure-sensitive triggering component 1024. The second part 10112 is disposed between the keycap 101 and the second pressure-sensitive triggering component 1025 and can transmit pressure from the keycap 101 to the second pressure-sensitive triggering component 1025.

[0104] In the specific implementation, combined with Figure 11 As shown, the suspension column 108 is in direct contact with the keycap 101 and the dome assembly 1031 (without adhesion or welding). Simultaneously, the ECG conductive steel sheet 1023 is directly connected to the pressure-sensitive steel sheet 1021 and isolated from the suspension column 108. The pressure-sensitive steel sheet 1021 is split into left and right sides, which are respectively fixedly connected to the housing 201 of the smartwatch 200. In this embodiment, the support assembly 10211 and the limiting assembly 105 used to support the housing 201 and the pressure-sensitive steel sheet 1021 are disassembled into two parts and disposed on both sides of the suspension column 108. The support assembly 10211 and the limiting assembly 105 are integrated with the pressure-sensitive steel sheet 1021 and directly fixedly connected to the housing 201, thereby achieving fixed support for the pressure-sensitive steel sheet 1021. Compared to the solution where the torque required for the bending deformation of the pressure-sensitive steel sheet 1021 is provided only by the contact surface between the dome component 1031 and the bottom support component 10211 of the pressure-sensitive steel sheet 1021, due to the miniaturization requirements of wearable devices, this contact surface may be small (for example, it may be a circle with a diameter of 0.8 mm). In practical applications, it may not be able to provide sufficient torque support. This solution avoids the tilting of the pressure-sensitive steel sheet 1021 during the pressing process and improves the sensitivity of the deformation structure.

[0105] In this embodiment, since the pressure-sensitive steel sheet 1021 is directly fixedly connected to the housing 201, the support point supporting the pressure-sensitive steel sheet 1021 no longer moves downward. To trigger the dome assembly, additional support points are added, such as... Figure 11 The suspension column 108 is shown in the figure. The ECG conductive steel sheet 1023 is not connected to the suspension column 108, but is directly connected to the pressure-sensitive steel sheet 1021. Therefore, the suspension column 108 can be made of non-metallic or other non-conductive materials to ensure the quality of the signal transmitted by the ECG conductive steel sheet 1023 (such as the ECG signal).

[0106] In this embodiment, by decoupling the conduction path of the physical key conduction component from the triggering path of the pressure-sensitive triggering component, the pressure-sensitive steel sheet 1021 and the housing 201 can be fixedly connected by adhesive or screw fastening. This reduces the impact of errors caused by design and manufacturing inconsistencies on the pressure-sensitive system, i.e., the tolerance requirements for the gap control of the key 100, and improves the manufacturability of the solution. In the specific implementation process, an elastomer (spring or silicone) can be set in the floating column to absorb the gap between the physical key conduction component 103, the floating column 108, and the keycap 101, ensuring that the three maintain good contact during use.

[0107] The buttons provided in this application embodiment are used for side interaction of wearable devices, combined with Figure 7 As shown, users can perform different interaction scenarios by pressing the keycap 101: for example, users can perform actions such as light pressing, long pressing, and double-clicking on the keycap 101, and the pressure-sensitive sensor 1022 can recognize and report the corresponding gestures; users can slide on the keycap, and the pressure-sensitive sensor 1022 can report the sliding speed and sliding distance; users can press hard or long-press at any position on the keycap to trigger the dome component 1031 and realize the corresponding functions (such as returning, powering off, forced restart, etc.).

[0108] In summary, with the button 100 provided in this application embodiment, users only need to press the button to control different operations and functions. When performing different functions, only the pressure of pressing the button needs to be adjusted, without the need for additional operations. Therefore, it can improve operating efficiency and enhance user experience.

[0109] The buttons provided in the above embodiments of this application can also be applied to other electronic devices, such as mobile phones, tablets, laptops, or augmented reality (AR) / virtual reality (VR) terminal devices.
