Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to a button assembly for electronic devices and an electronic device. Background Technology

[0002] With the continuous advancement of technology, electronic devices have become an indispensable part of people's lives, with increasingly diverse and rich functions. Today, electronic devices can not only easily capture high-definition images and play videos, but also perform a variety of complex operations through various button components. Button components typically consist of buttons and triggering devices. The buttons are generally located on the casing of the electronic device, while the triggering device is located inside the casing. Users simply press the button lightly, and the triggering device is activated, sending different commands to the device to complete various operations such as adjusting volume and switching modes. For example, the volume control button on the device casing allows users to easily adjust the volume with a simple press. Some button components also feature a sliding function, allowing users to quickly turn pages, adjust volume, and perform other convenient functions, greatly enhancing the user experience.

[0003] Buttons in electronic devices can be installed in two ways: detachable and non-detachable. Detachable buttons are separate from the device's housing and can move within the housing when pressed. Non-detachable buttons, on the other hand, are integrated with the housing. Detachable buttons negatively impact the device's waterproofing and dustproofing, while non-detachable buttons offer better sealing, contributing to the device's waterproofing and dustproofing.

[0004] There are various types of triggering devices in button assemblies, commonly including mechanical switches, metal springs, and pressure-sensitive modules. Among them, pressure-sensitive modules stand out due to their unique pressure detection function. They can accurately detect changes in pressure through force deformation to trigger signals and support multi-level pressure recognition. The pressure-sensitive module is fixed to the button (usually a non-detachable button) by adhesive bonding (e.g., adhesive backing). When the user presses the button, the pressure is transmitted to the pressure-sensitive module. However, the flexibility of the adhesive material can cause the pressure to be dispersed, and deformation of the adhesive material can absorb some of the pressure. This requires the user to apply greater pressure to achieve the pressing and sliding functions, significantly affecting the button assembly's sensitivity and thus greatly diminishing the user experience.

[0005] In summary, existing electronic devices suffer from low sensitivity of non-detachable button components. Utility Model Content

[0006] The button assembly and electronic device provided in this application embodiment solve the problem of low sensitivity of non-detachable button assemblies in the prior art.

[0007] This application provides a button assembly for an electronic device, including a button, a pressure-sensitive module, and a contact portion. The button includes a structural component having a first surface; the pressure-sensitive module has a first side surface, which is disposed opposite to the first surface in a first direction; the contact portion is disposed between the structural component and the pressure-sensitive module, and at least a portion of the contact portion is located between the first surface and the first side surface, with a gap between the first surface and the first side surface.

[0008] When a button is pressed, the pressing force in the first direction on the structural component is directly transmitted to the pressure-sensitive module through the abutment part, causing the pressure-sensitive module to elastically deform and generate displacement in the first direction in order to detect the external pressing force.

[0009] The button assembly provided in this application is used in electronic devices. Users can perform various operations by pressing the button assembly, meeting different user needs and enriching the user experience. The button assembly includes a button, a pressure-sensitive module, and a contact part. The pressure-sensitive module is a triggering device, or a trigger switch. When a user presses the button, the pressure is transmitted to the pressure-sensitive module, triggering the module to send commands. The button has a structural component, and a contact part is provided between the structural component and the pressure-sensitive module. The structural component is the structure in the button that contacts the contact part. When a user presses the button, the pressure is transmitted to the contact part through the structural component, and the contact part then directly transmits the pressure to the pressure-sensitive module. The pressure-sensitive module detects the external pressing force through elastic deformation in a first direction.

[0010] Specifically, at least part of the contact portion is located between the first side of the pressure-sensitive module and the first surface of the structural component, and there is a gap between the first surface and the first side. Therefore, during the transmission of pressure, the pressure-sensitive module only contacts the button through the location of the contact portion, resulting in a small contact area and a concentrated distribution of pressure on the pressure-sensitive module. This makes the response area of ​​the pressure-sensitive module more concentrated. Furthermore, there is no adhesive material between the contact surfaces of the button (especially non-detachable buttons) and the pressure-sensitive module (or, in other words, there is no need for adhesive material to transmit pressure between the button and the pressure-sensitive module), and the pressure is not absorbed by the deformation of adhesive material. Therefore, even if the user applies very little pressure to the button, the pressure can be directly and quickly transmitted to the pressure-sensitive module and successfully triggered, reducing pressure dispersion and loss. This results in higher sensitivity of the button assembly, ensuring a better tactile feel for the user and improving the user experience.

[0011] In summary, the button assembly provided in this application embodiment has high pressing sensitivity, which can ensure the user's pressing feel and improve the user experience.

[0012] In one possible implementation, one end of the abutment is connected to one of the pressure-sensitive module and the structural component, while the other end contacts the other.

[0013] Alternatively, the abutting portion includes a first part and a second part disposed opposite to each other in a first direction, with one end face of the first part and the second part facing each other in contact, and one end face of the first part and the second part being disposed opposite to each other connected to the pressure-sensitive module and the structural component, respectively.

[0014] Using the above solution, the pressure applied to the structural component is directly transmitted to the pressure-sensitive module through the abutment part, resulting in rapid pressure feedback and improved user sensitivity and tactile feel. Furthermore, the abutment part can take various forms and is flexible in design, adapting to different design schemes to achieve its function, thus demonstrating high feasibility.

[0015] In one possible implementation, the abutment portion is configured as a protrusion; wherein the protrusion is formed on the pressure-sensitive module and protrudes from the first side, and one end face of the protrusion away from the first side contacts the first surface of the structural member; or, the protrusion is formed and protrudes from the first surface of the structural member, and one end face of the protrusion away from the first surface contacts the pressure-sensitive module.

[0016] The first part of the abutment is configured as a protrusion formed on the pressure-sensitive module, and the second part of the abutment is configured as a protrusion formed and protruding from the first surface.

[0017] Using the above solution, the pressure-sensitive module and the structural component can directly contact each other through a contact part. This contact part is designed as a protrusion, reducing or avoiding the dispersion and absorption of pressing force over a large area. This allows for faster response to pressing force, improves the sensitivity of the button component, ensures a good pressing feel, and thus enhances the user experience. The protrusion can be formed on the pressure-sensitive module or on the structural component, offering flexibility and diverse implementation options.

[0018] In one possible implementation, the protrusion can be a dot or a rib. When the protrusion is a dot, the contact surface between the protrusion and the first surface or the pressure-sensitive module is relatively flat and stable, which can quickly transmit the pressing force, trigger the function, and ensure the pressing feel of the button component; when the protrusion is a rib, the protrusion processing technology is simple and easy to complete.

[0019] In one possible implementation, there are multiple abutting portions, which are spaced apart in a second direction; wherein the second direction is perpendicular to the first direction, the first direction is parallel to the thickness direction of the pressure-sensitive module, and the second direction is parallel to the length direction of the pressure-sensitive module.

[0020] By adopting the above solution, multiple contact points can make the pressure transmission area between the pressure-sensitive module and the structural components more evenly distributed, so that the pressure-sensitive module can be quickly triggered when the user presses the button at any position, providing the user with a good user experience.

[0021] In one possible implementation, there are two abutting portions; in the second direction, one abutting portion is located at or near the first end of the pressure-sensitive module, and the other abutting portion is located at or near the second end of the pressure-sensitive module.

[0022] By employing the above solution, the two abutment portions spaced apart in the second direction can quickly respond to press commands in different areas, completing different press functions. Furthermore, the two abutment portions are distributed at both ends of the pressure-sensitive module, covering the sensing area of ​​the module in the second direction, avoiding the situation where the pressure-sensitive module cannot respond when the user presses a specific button location due to overly concentrated abutment portions. The spaced abutment portions in the second direction also facilitate the user's sliding operation commands; that is, the pressure-sensitive module below the button detects different pressure distributions, and by analysis, can determine the sliding path and speed of the finger to achieve different functions, providing users with a richer and more convenient interactive experience.

[0023] In one possible implementation, the two abutting parts are symmetrically arranged in the second direction.

[0024] By adopting the above solution, the pressure-sensitive module can receive the pressing force more evenly and respond to the user's pressing command more quickly, thereby improving the pressing sensitivity of the button component.

[0025] In one possible implementation, the pressure-sensitive module has protruding fixing parts at both ends along the second direction, and each fixing part is fixedly connected to the structural component to fix the pressure-sensitive module to the structural component; wherein, the second direction is perpendicular to the first direction and parallel to the length direction of the pressure-sensitive module.

[0026] By adopting the above solution, the pressure-sensitive module is fixedly connected to the structural component through a fixing part, which ensures the reliability of the pressure-sensitive module's installation and fixation in the housing. Furthermore, compared to fixing the pressure-sensitive module using adhesive (e.g., adhesive backing), this method reduces the dispersion and absorption of pressure by the adhesive material, thereby reducing pressure loss and allowing users to trigger the function with a light press of the button.

[0027] In one possible implementation, the fixing part is fixedly connected to the structural component by means of threads, snap-fit, or welding.

[0028] Using the above solutions, when the fixing part and the structural component are fixedly connected by threads, the pressure-sensitive module is easy to disassemble and reassemble, facilitating maintenance and component replacement; when the fixing part and the structural component are fixedly connected by snap-fit, assembly can be completed quickly during installation, resulting in lower manufacturing costs; when the fixing part and the structural component are fixedly connected by welding, it provides reliable connection, waterproof and dustproof sealing, and the process is simple and easy to implement.

[0029] In one possible implementation, a protruding mounting platform is provided on the first surface of the structural member in the area corresponding to the fixing part. In the second direction, the mounting platform is located outside the pressure-sensitive module and is spaced apart from the end face of the corresponding end of the pressure-sensitive module. The fixing part is fixedly connected to the mounting platform to be fixedly connected to the structural member via the mounting platform.

[0030] The above solution includes a mounting platform on the structural component, which securely connects the pressure-sensitive module to the structural component, thus ensuring the structural reliability of the button assembly during the pressing process.

[0031] In one possible implementation, the fixing part and the mounting platform are stacked in a first direction, and the fixing part is threadedly connected to the mounting platform by fasteners; alternatively, the surfaces of the fixing part and the mounting platform opposite to each other are welded together. Alternatively, the mounting platform has a slot, and the fixing part engages with the slot.

[0032] In one possible implementation, the pressure-sensitive module includes a bracket and a pressure-sensitive element, which are stacked and fixedly disposed on the bracket in a first direction, and an abutment portion is disposed between the first surface of the structural member and the bracket.

[0033] When the button is pressed, the pressing force in the first direction on the structural component is directly transmitted to the bracket through the abutment part, causing the bracket and the pressure-sensitive element to elastically deform and displace in the first direction, so as to detect the external pressing force through the pressure-sensitive element.

[0034] Using the above solution, when the button is pressed, the pressing force received by the button can be directly transmitted to the bracket of the pressure-sensitive module through the abutment part, thereby causing the pressure-sensitive element fixed on the bracket to produce an elastic deformation displacement in the first direction. The pressure-sensitive element can transmit the signal to the controller to trigger the function. At this time, the pressure-sensitive module has a simple structure and a fast response, which helps to improve the user's pressing feel and improve the user experience.

[0035] In one possible implementation, the bracket has a first surface and a second surface disposed opposite to each other in a first direction, with the first surface facing the first surface. The first surface and / or the second surface of the bracket are covered with pressure-sensitive elements.

[0036] When the first side of the bracket is covered with a pressure-sensitive element, the side of the pressure-sensitive element facing away from the bracket constitutes the first side of the pressure-sensitive module, and the pressure-sensitive element has a through hole for the abutment portion to pass through.

[0037] When the first side of the bracket is not covered with a pressure-sensitive element, the first side of the bracket constitutes the first side of the pressure-sensitive module.

[0038] Using the above scheme, the pressure-sensitive element, fixed on the bracket, can synchronously generate displacement in the first direction with the bracket. The amount of displacement generated by elastic deformation is used to detect the pressing force. Once the pressure-sensitive element detects the signal, it triggers the button function.

[0039] In one possible implementation, the support is configured as a plate-like structure, with the first and second surfaces being two opposite surfaces of the plate-like structure along its thickness direction.

[0040] The area corresponding to the abutment in the bracket is provided with a groove. The groove is recessed from the second surface toward the first surface, forming a deformable space that allows the abutment to move in the first direction.

[0041] When the button is pressed, the abutting part causes at least a portion of the bracket to move into the deformation space.

[0042] By adopting the above solution, the plate-shaped bracket can fully utilize the installation space of the button components, allowing users to quickly trigger functions when touching the corresponding housing part of the pressure-sensitive module, ensuring a good user experience. Furthermore, the bracket has grooves that create deformation space at the contact point. The bracket is also thinner at the grooved areas, making it easier to deform and facilitating the deformation of the pressure-sensitive element at that location. This results in faster and more precise pressure transmission at the contact point, improving the sensitivity of the button components.

[0043] In one possible implementation, the pressure-sensitive element is a pressure-sensitive FPC.

[0044] In one possible implementation, when the pressure-sensitive module has protruding fixing parts at both ends along the second direction, the fixing parts protrude outward from the end face of the bracket along the second direction.

[0045] With the above solution, the fixing part is formed by the two ends of the bracket protruding outward in the second direction. While the bracket is structurally stable, it can also enhance the connection strength between the bracket and the structure.

[0046] In one possible implementation, the structural components are made of a rigid material, and the support frame is also made of a rigid material.

[0047] By adopting the above solution, the pressing force can be evenly diffused in the rigid material and quickly transmitted to the next component, reducing the loss during the transmission process, enabling the pressure-sensitive element to respond quickly to the pressing force, and improving the pressing sensitivity of the button assembly.

[0048] In one possible implementation, the abutment is configured as a protrusion, which, when formed on the pressure-sensitive module, forms and protrudes from the first surface of the bracket.

[0049] The abutment portion is configured as a protrusion. When the protrusion is formed on the first surface of the structural member, the end face of the protrusion away from the first surface contacts the first surface of the bracket.

[0050] When the abutment includes a first part and a second part, the first part is configured as a protrusion formed on the first surface of the bracket.

[0051] A second aspect of this application provides an electronic device, including a housing and a button assembly provided in the first aspect and any possible implementation thereof, wherein the button assembly is mounted on the housing.

[0052] The electronic device provided in this application embodiment has high button sensitivity, good pressing feel, and a more comfortable user experience.

[0053] In one possible implementation, the structural component is the keycap of the button, and part of the housing is used as the keycap.

[0054] In one possible implementation, the keycap and the housing are a single integrated structure.

[0055] By adopting the above solution, electronic devices can have better waterproof and dustproof performance, which helps to improve their reliability.

[0056] In one possible implementation, the housing includes a middle plate and a frame, with the frame surrounding the edge of the middle plate.

[0057] The frame has a mounting groove that is recessed from the inner wall of the frame along the wall thickness towards the outer wall. The pressure-sensitive module is set in the mounting groove, and the area at the bottom of the mounting groove in the frame is used as a keycap.

[0058] In one possible implementation, the outer surface of the button assembly is lower than the outer surface of the housing, or the outer surface of the button assembly is flush with the outer surface of the housing.

[0059] By adopting the above solution, the button components will not be too conspicuous on the edge of the electronic device, which is beneficial to the flatness and aesthetics of the electronic device. Attached Figure Description

[0110] With the rapid development of technology, electronic devices are increasingly widely used, and their types and functions are constantly being enriched to meet people's growing needs for digital life. Electronic devices typically include button components, allowing users to control various functions such as power on / off and volume adjustment. However, current non-detachable button components in electronic devices suffer from poor button sensitivity, affecting the user experience. To address this issue, this application provides an electronic device where the button component achieves direct contact between the button and the pressure-sensitive module through a contact portion, improving the button component's sensitivity and ensuring a better tactile feedback for the user, thus enhancing the overall user experience.

[0111] The electronic devices provided in this application embodiment may be, but are not limited to, mobile phones, tablets, wearable smartwatches, and other electronic devices. First, the basic structure of the electronic device will be described below with reference to the accompanying drawings. For ease of explanation and understanding, a mobile phone will be used as an example to specifically explain the structure and function of the electronic device.

[0112] Please see Figures 1a-1d , Figure 1a This is a three-dimensional structural diagram of the electronic device according to an embodiment of this application. Figure 1b This is a schematic diagram of the rear structure of the electronic device according to an embodiment of this application (the back cover has been removed from the figure). Figure 1c This is a schematic cross-sectional view of the electronic device according to an embodiment of this application. Figure 1d This is a schematic diagram of a second cross-sectional structure of an electronic device according to an embodiment of this application.

[0113] like Figures 1a-1d As shown, the electronic device 100 includes a housing 1 and a display screen 14. The housing 1 serves to protect the electronic device 100 and support the entire device. It has an internal space for housing the electronic components and battery 15 inside the electronic device 100. The display screen 14 is disposed in the housing space of the housing 1 and is connected to the housing 1.

[0114] Specifically, the display screen 14 is used to display images. The display screen 14 may be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc. The embodiments of this application do not limit the type and specific structure of the display screen 14.

[0115] It will be understood by those skilled in the art that the specific structure of the housing 1 is not limited. For example... Figure 1cAs shown, in one possible implementation, the housing 1 includes a middle frame 11 and a back cover 12, with the middle frame 11 including a border 112. The back cover 12, also called a battery cover, is located on the back of the electronic device 100. The back of the electronic device 100 can be understood as the side facing away from the user when using the electronic device 100, i.e., the surface facing away from the display screen 14 in the thickness direction Z3 of the electronic device. The border 112 surrounds the edge of the back cover 12 to serve as the outer border of the electronic device 100. In one example, the border 112 may include four sides surrounding the display screen 14 to help secure the display screen 14. In another example, the border 112 may also include only three sides, two sides, etc. (e.g., in a foldable electronic device), and this embodiment does not limit this.

[0116] like Figure 1c As shown, in one possible implementation, the middle frame 11 further includes a middle plate 111, which is spaced apart from the rear cover 12 in the thickness direction Z3 of the electronic device, and the frame 112 also surrounds the outer edge of the middle plate 111. The middle plate 111 is used to support the display screen 14 and the internal components of the electronic device 100. Specifically, as shown... Figure 1c As shown, the middle plate 111 can be positioned in the center of the frame 112, with the display screen 14 and the back cover 12 mounted on either side of the middle plate 111. This allows for the mounting of components on both the middle plate 111 and the back cover 12, providing more mounting space for electronic components. Figure 1d As shown, in one possible implementation, the middle plate 111 and the back cover 12 can be reused as a single structure. Specifically, in the thickness direction Z3 of the electronic device, the display screen 14 is mounted on one side of the frame 112, while the middle plate 111 is connected to the other side of the frame 112 and serves as the back cover 12 of the electronic device 100. Alternatively, the entire middle frame 11 can be understood as having a "U-shaped" cross-section. In this way, the middle plate 111 simultaneously performs the functions of both the middle plate 111 and the back cover 12, eliminating the need for an additional back cover 12, which helps save space and reduce the overall thickness and weight of the device.

[0117] It should be noted that the middle frame 11 can be a separate structure or a one-piece structure, and this application embodiment does not limit this. In one example, the middle frame 11 is a separate structure, that is, the middle plate 111 and the frame 112 are two different parts, which can be assembled together by snap-fit, fastening, or other means, and can be separated when disassembly is required. In another example, the middle frame 11 is a one-piece structure. Specifically, the middle plate 111 and the frame 112 of the middle frame 11 can be manufactured by one-piece molding or assembled by permanent connection methods such as welding, and this application embodiment does not limit this.

[0118] It should be noted that this application does not limit the specific layout of the internal space of the electronic device 100. The accompanying drawings are for illustrative purposes only. The electronic device 100 may include more or fewer components.

[0119] In one possible implementation, such as Figure 1a and Figure 1b As shown, the electronic device 100 also includes a button assembly 2, which is mounted on the housing 1. The button assembly 2 includes a button 3, allowing users to perform various operations by pressing the button assembly 2, meeting different user needs and enriching the user experience. In other words, the button assembly 2 can assist the electronic device 100 in achieving multiple functions. For example, the button assembly 2 can act as a power switch to turn the device on or off; it can also be used to adjust volume, brightness, and other functions, as well as switch between different modes or functions, such as camera mode and airplane mode. With technological advancements, the button assembly 2 also supports more complex interaction methods. In one example, the button assembly 2 can be used to quickly turn pages, adjust volume, and switch modes by sliding the button 3. In another example, users can perform different functions by long-pressing or short-pressing, such as long-pressing the power button to enter recovery mode and short-pressing to return to the main interface. The number of button assemblies 2 is unlimited; multiple button assemblies 2 can be set on the electronic device 100. In one example, multiple buttons 3 can be pressed simultaneously to achieve specific functions, such as restarting the device or taking a screenshot. It is understood that the embodiments of this application do not limit the specific functions implemented by the button assembly 2.

[0120] It should be noted that the installation location of the button component 2 in the electronic device 100 is not limited. In one possible implementation, the button component 2 can be placed at any position on the frame 112, and the user can perform different functions by pressing the button component 2. In one example, such as Figure 1a and Figure 1b As shown, the button assembly 2 is located on the side of the frame 112 near the top of the electronic device 100. The top of the electronic device 100 is usually equipped with a motherboard 16, which integrates the main circuit system of the device and undertakes key tasks such as data processing, signal transmission and function control, ensuring the coordinated operation and performance of the various modules of the electronic device 100.

[0121] Those skilled in the art will understand that the button assembly 2 includes a button 3 and a triggering device (such as a microswitch or touch sensor). When a user presses button 3, the triggering device detects physical contact or pressure change and converts it into an electrical signal. This signal is transmitted to the mainboard 16 via a flexible printed circuit (FPC) or wires, and after being parsed, executes the corresponding function command (such as volume adjustment, power switch, etc.), thereby realizing the feedback response between user operation and device function. In this way, the button assembly 2, located at the top, is convenient for users to hold with one hand and naturally touch with their thumb or forefinger, and it also helps to shorten the circuit path between the triggering device in the button assembly 2 and the mainboard 16.

[0122] In another example, the button component 2 may also be located in the bottom area of ​​the electronic device 100, and this embodiment of the application does not limit this.

[0123] It should be noted that the embodiments of this application do not limit the type of triggering device. The triggering device can be set as pressure-sensitive module 4, or it can be a mechanical column, metal spring, etc.

[0124] Please see Figures 2a to 2b , Figure 2a This is a structural diagram of a button assembly in a reference design. Figure 2b This is a schematic diagram of the structure of a button assembly in an electronic device in a reference design.

[0125] like Figure 2a and Figure 2b As shown, in one reference design, the button 3' of the electronic device 100' is a detachable structure, meaning the button 3' and the housing 1' of the electronic device 100' are separate components. Specifically, the button 3' can be fixed by a cantilever beam snap-fit ​​structure, magnetic fixation, or adhesive bonding, allowing the button 3' to move on the housing 1' during pressing. When the button 3' is pressed, the triggering device 4' provides feedback on the pressing force, thereby realizing the specific function of the button assembly 2'. However, there is usually a gap between the detachable button 3' and the housing 1', which can adversely affect the waterproof and dustproof properties of the electronic device 100', thus affecting the overall reliability of the device.

[0126] Please see Figure 3 , Figure 3 This is a cross-sectional view of the button assembly in another reference design.

[0127] like Figure 3As shown, in another reference design, the button 3 of the button assembly 2" in the electronic device 100" is a non-detachable structure, that is, the button 3" and the housing 1" are an integral structure, which improves the waterproof and dustproof function of the whole device. Furthermore, the triggering device 4" of the button assembly 2" is a pressure-sensitive module, which is fixedly connected to the button 3" by an adhesive layer 5" (e.g., adhesive backing). When the user presses the button 3", due to the high flexibility of the adhesive material of the adhesive layer 5", the pressing force is significantly dispersed in the adhesive layer 5", and the flexible adhesive material such as the adhesive backing may also deform, absorbing some of the pressing force, resulting in a smaller pressing force transmitted to the triggering device 4". Therefore, the user needs to apply greater pressing force to achieve the pressing and sliding functions of the button 3", which greatly affects the pressing sensitivity of the button assembly 2", and thus the user experience.

[0128] Based on this, this application provides a button assembly 2, which can directly transmit pressing force to the triggering device (e.g., pressure-sensitive module 4) through the abutting part 5 between the button 3 and the triggering device (e.g., pressure-sensitive module 4), and quickly provide feedback to external pressing force, thereby improving the pressing sensitivity of the button assembly 2, ensuring the user's pressing feel, and improving the user's user experience.

[0129] The following section will describe the specific structure of button assembly 2.

[0130] Please see Figures 4 to 5c , Figure 4 This is a structural diagram showing the location of the button assembly in the housing according to an embodiment of this application. Figure 5a This is a schematic diagram of a first cross-sectional structure of the button assembly according to an embodiment of this application. Figure 5b for Figure 5a A magnified view of part A in the middle. Figure 5c This is a schematic diagram of the first cross-sectional structure of the button assembly in an embodiment of this application from another perspective.

[0131] like Figures 4 to 5b As shown, the button assembly 2 includes a button 3, a pressure-sensitive module 4, and a contact portion 5. The button 3 includes a structural member 31 having a first surface 311. The pressure-sensitive module 4 has a first side surface 41, which is disposed opposite to the first surface 311 in a first direction X1. The contact portion 5 is disposed between the structural member 31 and the pressure-sensitive module 4, and at least a portion of the contact portion 5 is located between the first surface 311 and the first side surface 41, with a gap S between the first surface 311 and the first side surface 41.

[0132] When button 3 is pressed, the pressing force on the structural component 31 in the first direction X1 is directly transmitted to the pressure-sensitive module 4 through the abutment part 5, causing the pressure-sensitive module 4 to elastically deform and generate displacement in the first direction X1 to detect the external pressing force.

[0133] The first direction X1 can be parallel to the width direction Y3 or the length direction X3 of the electronic device, or it can be parallel to the thickness direction X2 of the pressure-sensitive module. This application embodiment does not limit this.

[0134] like Figure 5a and Figure 5b As shown, users can perform various operations by pressing the button assembly 2, meeting different user needs and enriching the user experience. The button assembly 2 includes a button 3, a pressure-sensitive module 4, and a contact part 5. The pressure-sensitive module 4 is a triggering device, which can also be understood as a trigger switch. In one possible implementation, the triggering device is the pressure-sensitive module 4. The user can transmit pressure to the pressure-sensitive module 4 by pressing the button 3, triggering the module and sending commands. The button 3 has a structural component 31, and a contact part 5 is provided between the structural component 31 and the pressure-sensitive module 4. The structural component 31 is the structure in the button 3 used to contact the contact part 5. When the user presses the button 3, the pressure is transmitted to the contact part 5 through the structural component 31, and the contact part 5 then directly transmits the pressure to the pressure-sensitive module 4. The external pressure is detected by the elastic deformation of the pressure-sensitive module 4 in the first direction X1.

[0135] Specifically, such as Figure 5a and Figure 5b As shown, at least a portion of the contact part 5 is located between the first side surface 41 of the pressure-sensitive module 4 and the first surface 311 of the structural member 31. There is a gap S between the first surface 311 and the first side surface 41. That is, the areas other than the area where the contact part 5 is located have a gap S. Therefore, during the transmission of pressure, the pressure-sensitive module 4 only contacts the button 3 through the location of the contact part 5, resulting in a smaller contact area and a more concentrated distribution of pressure on the pressure-sensitive module 4. This makes the response area of ​​the pressure-sensitive module 4 more concentrated. Furthermore, there is no adhesive material between the contact surfaces of the button 3 (especially non-detachable buttons) and the pressure-sensitive module 4 (or it can be understood that there is no need for adhesive material to transmit pressure between the button 3 and the pressure-sensitive module 4), and the pressure will not be absorbed by the deformation of the adhesive material. Therefore, even if the user applies very little pressure to button 3, especially for button 3 in the non-detachable button assembly 2, only a small amount of pressure is needed to directly and quickly transmit the pressure to the pressure-sensitive module 4 and successfully trigger the pressure-sensitive module 4. This reduces the dispersion and loss of pressure, making the button assembly 2 more sensitive, ensuring the user's pressing feel, and improving the user experience.

[0136] In simple terms, when a user applies pressure to a specific area of ​​the electronic device 100, the pressure applied to the button 3 can be directly transmitted to the pressure-sensitive module 4 through the contact part 5. This reduces the loss of pressure during transmission through other components and improves the response speed. As a result, the pressure-sensitive module 4 can receive the user's pressure feedback more directly and realize the pressing function with only a small amount of pressure applied by the user.

[0137] In summary, the button assembly 2 provided in this application embodiment has high pressing sensitivity, which can ensure the user's pressing feel and improve the user's user experience.

[0138] It should be noted that the specific structure of button 3 is not limited in the embodiments of this application. One possible implementation is as follows: Figure 1a and Figure 5a As shown, in one example, structural component 31 is the keycap 32 of button 3, and part of housing 1 is used as keycap 32, meaning button 3 and housing 1 are an integral structure. Alternatively, it can be understood that button 3 is a non-detachable structure, and correspondingly, button assembly 2 is also a non-detachable structure. In this case, the location of button assembly 2 has good sealing performance, and there are no gaps between button 3 and housing 1, enabling electronic device 100 to have good waterproof and dustproof performance, which is beneficial to improving its reliability. In another example, button 3 and housing 1 can also be a separate structure; this embodiment does not limit this.

[0139] In other possible implementations, the structural component 31 of button 3 can also be a scissor-type structure. Pressing button 3 triggers the scissor-type structure to generate displacement, which in turn triggers the triggering device to achieve functional activation.

[0140] The material of structural component 31 is not limited. In one possible implementation, structural component 31 is made of a rigid material. In one example, structural component 31 can be a metallic material, such as aluminum alloy, titanium alloy, stainless steel, copper alloy, etc. In another example, structural component 31 can also be a non-metallic material, such as ceramic or other polymer materials. This application embodiment does not impose any restrictions on this. In this way, the pressing pressure can be evenly diffused in the rigid material and quickly transmitted to the next component (abutting part 5), reducing the loss during the transmission process, enabling the pressure-sensitive module 4 to respond quickly to the pressing pressure, and improving the pressing sensitivity of the button assembly 2.

[0141] Furthermore, in one possible implementation, the outer surface of the button assembly 2 is lower than the outer surface of the housing 1, that is, the outer surface of the button 3 is recessed relative to the outer surface of the housing 1, or, as... Figure 1aAs shown, the outer surface of the button assembly 2 is flush with the outer surface of the housing 1. This makes the button assembly 2 less conspicuous on the frame 112 of the electronic device 100, contributing to the smoothness and aesthetics of the electronic device 100. In other possible implementations, the outer surface of the button assembly 2 may also be higher than the outer surface of the housing 1; this embodiment does not limit this.

[0142] Furthermore, this application embodiment does not limit the installation position of the button assembly 2. In one possible implementation, such as Figure 4 , Figure 5a and Figure 5c As shown, the frame 112 is provided with a mounting groove 131. The mounting groove 131 is recessed from the inner wall surface 132 of the frame 112 along the wall thickness direction towards the outer wall surface 133. The pressure-sensitive module 4 is disposed in the mounting groove 131, and the area in the frame 112 located at the bottom 1311 of the mounting groove 131 is used as a keycap 32.

[0143] Please see Figures 6a to 10 , Figure 6a This is a schematic diagram of the contact portion in the button assembly according to an embodiment of this application. Figure 6b This is another schematic diagram of the contact portion in the button assembly according to an embodiment of this application. Figure 7 This is a schematic diagram of a second cross-sectional structure of the button assembly according to an embodiment of this application. Figure 8 This is a schematic diagram illustrating another possible implementation of the contact portion in the button assembly according to an embodiment of this application. Figure 9a This is a schematic diagram of a third cross-sectional structure of the button assembly according to an embodiment of this application. Figure 9b for Figure 9a A magnified view of part B in the middle section. Figure 10 This is a schematic diagram of the fourth cross-sectional structure of the button assembly in an embodiment of this application.

[0144] It should be noted that the position of the contact part 5 is not limited. For example... Figure 6a As shown, in one possible implementation, one end 511 of the abutment 5 is connected to either the pressure-sensitive module 4 or the structural member 31, while the other end 512 contacts the other. That is, the pressure applied to the structural member 31 is directly transmitted to the pressure-sensitive module 4 through the abutment 5, resulting in rapid pressure feedback and improved user sensitivity and tactile feedback. Furthermore, the abutment 5 can take various forms, offering flexible design and adaptability to different design schemes, thus demonstrating high feasibility.

[0145] In one example, such as Figure 6aAs shown, the abutment portion 5 is configured as a protrusion 52; wherein, the protrusion 52 is formed on the pressure-sensitive module 4 and protrudes from the first side surface 41, and the end face of the protrusion 52 away from the first side surface 41 contacts the first surface 311 of the structural component 31. In this way, the pressure-sensitive module 4 and the structural component 31 can directly contact each other through the abutment portion 5. The abutment portion 5 is configured as a protrusion 52, which reduces or avoids the dispersion and absorption of pressing pressure over a large area, so that the pressing pressure can be responded to more quickly, improve the sensitivity of the button assembly 2, ensure the pressing feel, and thus improve the user experience.

[0146] It should be noted that the end face of the protrusion 52 away from the first side 41 can just make contact with the first surface 311 of the structural member 31 (see...). Figure 6a Alternatively, it can be a pressure contact (not shown in the figure), that is, an interference fit between the structural component 31 and the pressure-sensitive module 4, so that the pressure-sensitive module 4 can respond to the user's pressing pressure more quickly and improve the pressing sensitivity of the button assembly 2.

[0147] like Figure 6b As shown, the end face of the protrusion 52 away from the first side 41 may not be in contact with the first surface 311 of the structural member 31. This application embodiment does not limit this. Those skilled in the art can understand that the displacement generated by the structural member 31 of the button 3 through the pressing pressure can trigger the pressure-sensitive module 4 to achieve the specific function.

[0148] Another possible implementation, such as Figure 7 As shown, the protrusion 52 is formed and protrudes from the first surface 311 of the structural member 31, and the end face of the protrusion 52 away from the first surface 311 contacts the pressure-sensitive module 4. That is to say, the protrusion 52 can be formed on the pressure-sensitive module 4 or on the structural member 31, and its structure is flexible and can be implemented in various ways.

[0149] In other possible implementations, such as Figure 8 As shown, the abutting part 5 includes a first part 513 and a second part 514 disposed opposite to each other in the first direction X1. The end faces of the first part 513 and the second part 514 are in contact with each other, and the end faces of the first part 513 and the second part 514 are respectively connected to the pressure-sensitive module 4 and the structural member 31.

[0150] Specifically, in one example, such as Figure 8As shown, the first portion 513 of the abutting part 5 is configured as a protrusion 52 formed on the pressure-sensitive module 4, and the second portion 514 of the abutting part 5 is configured as a protrusion 52 formed and protruding from the first surface 311. That is, when the abutting part 5 includes the first portion 513 and the second portion 514 disposed opposite to each other, the first portion 513 is located on the pressure-sensitive module 4, and the second portion 514 is located on the first surface 311 of the structural member 31. The contact between the pressure-sensitive module 4 and the structural member 31 is more precise, which is beneficial to improving the sensitivity of the button assembly 2 and ensuring the pressing feel.

[0151] It should be noted that when the abutment part 5 is located on the pressure-sensitive module 4, such as Figure 5a As shown, the contact part 5 and the pressure-sensitive module 4 can be an integral structure or a separate structure, and this application embodiment does not limit this.

[0152] Furthermore, the shape of the contact part 5 is not limited.

[0153] like Figure 5a As shown, the abutment portion 5 is configured as a protrusion 52. In one possible implementation, the protrusion 52 is a protrusion 521. In this case, the protrusion 52 and the first surface 311 (see...) Figure 5b ) or pressure-sensitive module 4 (see Figure 7 The contact surface of the button assembly 2 is relatively flat and stable, enabling rapid transmission of pressing pressure and triggering of functions, thus ensuring the pressing feel of the button assembly 2. The raised dot 521 refers to a small point or particle protruding from the surface of an object. These points or particles are usually higher than the surrounding surface by a certain distance, causing the raised dot 521 to protrude from the first surface 311 or the pressure-sensitive module 4. Furthermore, there is a gap S between the first surface 311 of the structural component 31 and the first side 41 of the pressure-sensitive module 4. The pressing pressure received by the button 3 can be directly transmitted to the pressure-sensitive module 4 through the raised dot 521, improving the pressing sensitivity of the button assembly 2.

[0154] It should be noted that the protrusion 521 can be mushroom-shaped, straight, cylindrical, spherical, peripheral, etc., and the embodiments of this application do not limit it.

[0155] In other possible implementations, such as Figure 9a and Figure 9b As shown, protrusion 52 is a raised rib 522, where raised rib 522 refers to a raised line or pattern machined on the surface of the workpiece. In this way, the machining process of protrusion 52 is simple and easy to complete.

[0156] It is understandable that the cross-sectional shape of the protrusion 521 perpendicular to the first direction X1 can be square, rectangular, polygonal, etc., and the cross-sectional shape of the protrusion 522 perpendicular to the first direction X1 can be a trapezoid with an arc. This can be understood as the fact that the processing technology of the protrusion 522 does not have high requirements for precision, making it more convenient to produce.

[0157] It should be noted that the number of abutment parts 5 is not limited. In one possible implementation, such as... Figure 5a and Figure 10 As shown, in one possible implementation, there are multiple abutment portions 5, which are spaced apart along the second direction Y1. The second direction Y1 is perpendicular to the first direction X1 and parallel to the length direction Y2 of the pressure-sensitive module. This allows the multiple abutment portions 5 to more evenly distribute the pressure transmission area between the pressure-sensitive module 4 and the structural component 31, enabling the pressure-sensitive module 4 to be quickly triggered when the user presses the button 3 at any position, providing a better user experience.

[0158] It should be noted that the structures of the contact portions 5 at different positions in the button assembly 2 may be the same or different, and this application embodiment does not impose any restrictions on this.

[0159] In one example, such as Figure 5a and Figure 5b As shown, there are two abutting portions 5. In the second direction Y1, one abutting portion 5 is located near the first end 42 of the pressure-sensitive module 4, and the other abutting portion 5 is located near the second end 43 of the pressure-sensitive module 4. Alternatively, in the second direction Y1, one abutting portion 5 is located at the first end 42 of the pressure-sensitive module 4, and the other abutting portion 5 is located at the second end 43 of the pressure-sensitive module 4. This embodiment of the application does not limit this.

[0160] Understandably, the two abutment portions 5 spaced apart on the second direction Y1 can quickly respond to press commands in different areas, completing different press functions. Furthermore, the two abutment portions 5 are distributed at both ends of the pressure-sensitive module 4, covering the sensing area of ​​the pressure-sensitive module 4 on the second direction Y1, avoiding the situation where the pressure-sensitive module 4 cannot respond when the user presses part of the button 3 due to overly concentrated abutment portions 5. The two abutment portions 5 spaced apart on the second direction Y1 also facilitate the user's sliding operation commands; that is, the pressure-sensitive module 4 below the button 3 will detect different pressure distributions, and by analysis, can determine the sliding path and speed of the finger to achieve different functions, providing the user with a richer and more convenient interactive experience.

[0161] One possible implementation is, such as Figure 5aAs shown, button assembly 2 can realize two functions: "volume +" and "volume -". Correspondingly, button assembly 2 includes two abutment parts 5. Therefore, users can increase the volume by pressing the position of the first end 42 of the corresponding pressure-sensitive element 46, and decrease the volume by pressing the position of the second end 43 of the corresponding pressure-sensitive element 46. To enrich the user experience, when the user needs to increase the volume, they can slide from the "volume -" button 3 area to the "volume +" button 3 area. At this time, the user does not need to apply pressure; they only need to slide their finger, making the user experience richer. Furthermore, the sliding command can also satisfy various functions such as scrolling, page switching, and returning to the homepage, providing users with a convenient and efficient operation method.

[0162] Furthermore, such as Figure 5a As shown, the two abutting parts 5 are symmetrically arranged in the second direction Y1. In this way, the pressure-sensitive module 4 can receive the pressing force more evenly and respond to the user's pressing command more quickly, thereby improving the pressing sensitivity of the button assembly 2.

[0163] In another example, the button assembly 2 may have three or more abutting portions 5, and this embodiment does not limit this. Figure 10 As shown, the button assembly 2 has five abutment portions 5. It can be understood that the more abutment portions 5 there are in the button assembly 2, the larger the contact area between the pressure-sensitive module 4 and the structural component 31. At this time, the pressing force applied to the button 3 is more likely to be dispersed, thus affecting the pressing sensitivity. In other words, a moderate number of abutment portions 5 in the button assembly 2 is more conducive to improving the sensitivity of the button 3.

[0164] In other possible implementations, the button assembly 2 can have one abutment 5. In this case, the button assembly 2 can trigger a function through the abutment 5 to complete the user's operation command. In one example, the abutment 5 is located in the middle area of ​​the structural member 31 in the button assembly 2, which can quickly respond to the pressing pressure at any position and ensure pressing sensitivity.

[0165] The specific structure of the pressure-sensitive module 4 will be illustrated below with reference to the accompanying drawings.

[0166] Please see Figures 11 to 14 , Figure 11 This is a schematic diagram of the bracket structure in the button assembly of this application embodiment. Figure 12 This is a schematic diagram of the pressure-sensitive element in the button assembly of this application embodiment. Figure 13 This is a fifth cross-sectional structural diagram of the button assembly according to an embodiment of this application. Figure 14 This is a schematic diagram of a pressure-sensitive module in the button assembly of this application.

[0167] In one possible implementation, such as Figure 5a and Figure 11 As shown, the pressure-sensitive module 4 includes a bracket 44 and a pressure-sensitive element 46. The pressure-sensitive element 46 and the bracket 44 are stacked and fixedly arranged in the first direction X1. The abutment portion 5 is disposed between the first surface 311 of the structural member 31 and the bracket 44.

[0168] When button 3 is pressed, the pressing force on the structural member 31 in the first direction X1 is directly transmitted to the bracket 44 through the abutment part 5, causing the bracket 44 and the pressure-sensitive element 46 to elastically deform and generate displacement in the first direction X1, so as to detect the external pressing force through the pressure-sensitive element 46.

[0169] In other words, when button 3 is pressed, the pressing force on button 3 can be directly transmitted to the bracket 44 of pressure-sensitive module 4 through the abutment part 5, thereby causing the pressure-sensitive element 46 fixed on the bracket 44 to produce an elastic deformation displacement in the first direction X1. The pressure-sensitive element 46 can transmit the signal to the controller to trigger the function. At this time, the structure of pressure-sensitive module 4 is simple and the response is fast, which is conducive to improving the user's pressing feel and improving the user's user experience.

[0170] Specifically, such as Figure 5a , Figure 11 and Figure 13 As shown, the bracket 44 has a first surface 442 and a second surface 443 disposed opposite to each other in a first direction X1, with the first surface 442 facing the first surface 311. In one possible implementation, one side of the bracket 44 is covered with a pressure-sensitive element 46, wherein, as... Figure 5c and Figure 14 As shown, the pressure-sensitive element 46 has a through hole 463 through which the abutment portion 5 passes. At this time, the pressure-sensitive element 46, by being fixed on the bracket 44, can synchronously generate displacement in the first direction X1 with the bracket 44, thereby detecting the pressing force through the amount of displacement generated by elastic deformation. When the pressure-sensitive element 46 detects the signal, it triggers the function of the button assembly 2.

[0171] In one example, the first surface 442 of the bracket 44 is covered with a pressure-sensitive element 46. In another example, such as Figure 13 As shown, the second surface 443 of the bracket 44 is covered with a pressure-sensitive element 46, but this embodiment of the application does not limit this.

[0172] Among them, such as Figure 13 As shown, when the first surface 442 of the bracket 44 is not covered with the pressure-sensitive element 46, the first surface 442 of the bracket 44 constitutes the first side surface 41 of the pressure-sensitive module 4.

[0173] It is understandable that when the user presses button 3, the structural component 31 of button 3 will undergo a slight deformation, thereby transmitting the pressing force to the pressure-sensitive module 4. At this time, the bracket 44 in the pressure-sensitive module 4 will undergo elastic deformation under the action of button 3, resulting in displacement in the first direction X1, thereby causing the pressure-sensitive element 46 fixed on the bracket 44 to deform, triggering an electrical signal, and realizing the function of button assembly 2.

[0174] It should be noted that in one possible implementation, such as Figure 5a As shown, the pressure-sensitive element 46 converts the pressing signal generated by the pressure-sensitive module 4 into an electrical signal through the signal transmission unit 466, and transmits it to the control center on the motherboard 16 to realize the specific function of the button assembly 2.

[0175] It should be noted that the embodiments of this application do not limit the fixing method between the pressure-sensitive element 46 and the bracket 44. In one possible implementation, the pressure-sensitive element 46 and the bracket 44 are fixed by an adhesive layer 6 (e.g., adhesive backing).

[0176] In other possible implementations, such as Figure 5a and Figure 5b As shown, pressure-sensitive elements 46 are covered on the first surface 442 and the second surface 443 of the bracket 44. At this time, the pressure-sensitive module 4 can trigger the specific function of the button assembly 2 by comparing and analyzing the deformation of the pressure-sensitive elements 46 covered on the first surface 442 and the second surface 443 of the bracket 44.

[0177] Specifically, such as Figure 5a , Figure 5b and Figure 12 As shown, the pressure-sensitive module 4 may include a first pressure-sensitive element 461 and a second pressure-sensitive element 462. In one example, the first pressure-sensitive element 461 is disposed on the first surface 442 of the bracket 44, and the second pressure-sensitive element 462 is disposed on the second surface 443 of the bracket 44. The first pressure-sensitive element 461 and the second pressure-sensitive element 462 transmit signals through a connection portion 465. Furthermore, the second pressure-sensitive element 462 includes a signal transmission portion 466, which enables communication with the motherboard 16. In another example, the first pressure-sensitive element 461 and the second pressure-sensitive element 462 may not have a connection portion 465, and the first pressure-sensitive element 461 and the second pressure-sensitive element 462 may communicate through their respective independent signal transmission portions 466. This embodiment of the application does not impose any limitations on this.

[0178] It should be noted that the specific structure of the support 44 is not limited in the embodiments of this application. In one possible implementation, such as... Figure 11As shown, the bracket 44 is configured as a plate-like structure, with the first surface 442 and the second surface 443 being two opposite surfaces of the plate-like structure along its thickness direction. In this way, the plate-like bracket 44 can fully utilize the installation space of the button assembly 2, allowing users to quickly trigger functions when touching the housing 1 portion corresponding to the pressure-sensitive module 4, ensuring a superior user experience.

[0179] In other possible implementations, the bracket 44 can also be configured as a long, block-like structure. Those skilled in the art will understand that the bracket 44 can generate elastic deformation to trigger the function of the pressure-sensitive module 4.

[0180] Furthermore, in one possible implementation, such as Figure 11 As shown, the bracket 44 has a groove 444 in the area corresponding to the abutment 5. The groove 444 is recessed from the second surface 443 toward the first surface 442, forming a deformation space 445 that allows the abutment 5 to move in the first direction X1. In this way, the bracket 44 is provided with a groove 444, which can form a deformation space 445 for the location of the abutment 5. Furthermore, the bracket 44 is thinner at the location of the groove 444, making it easier to deform and more convenient to drive the pressure-sensitive element 46 at that location to deform. When the button 3 is pressed, the abutment 5 drives at least a part of the bracket 44 to move into the deformation space 445, making the transmission of the pressing force at the abutment 5 faster and more accurate, and improving the sensitivity of the button assembly 2.

[0181] Furthermore, this application does not limit the specific structure of the pressure-sensitive element 46. In one possible implementation, the pressure-sensitive element 46 is a pressure-sensitive FPC464. A pressure-sensitive FPC464 is an electronic component combining a flexible printed circuit board (FPC) and pressure-sensitive technology. Pressure sensing functionality can be achieved by printing pressure-sensitive ink on a flexible substrate or by integrating a pressure-sensitive FPC464. A pressure-sensitive FPC464 typically includes a flexible substrate, a conductive layer, a pressure-sensitive layer, and a protective layer. The pressure-sensitive layer can be pressure-sensitive ink or a piezoresistor, used to detect pressure changes.

[0182] In other possible implementations, such as Figure 14 As shown, the pressure-sensitive element 46 can also be a component composed of piezoelectric ceramic 4671. Specifically, the pressure-sensitive element 46 can be a vibrator composed of piezoelectric ceramic 4671 and metal sheet 4672, used to detect different pressing pressures.

[0183] It should be noted that the material of the bracket 44 is not limited in this embodiment. In one possible implementation, the bracket 44 is made of a rigid material. In one example, the bracket 44 can be a metal material, such as aluminum alloy, titanium alloy, stainless steel, copper alloy, etc. In another example, the bracket 44 can also be a non-metallic material, such as ceramic or other polymer materials. This embodiment does not limit this. In this case, the pressing pressure can be evenly diffused in the rigid material and quickly transmitted to the next component, reducing the loss in the transmission process, enabling the pressure-sensitive element 46 to respond quickly to the pressing pressure, and improving the pressing sensitivity of the button assembly 2.

[0184] Please see Figures 15 to 16 , Figure 15 This is a seventh cross-sectional structural diagram of the button assembly according to an embodiment of this application. Figure 16 This is an eighth cross-sectional structural diagram of the button assembly in an embodiment of this application.

[0185] It should be noted that this application does not limit the fixing structure of the pressure-sensitive module 4. In one possible implementation, such as... Figure 5a , Figure 11 As shown, the pressure-sensitive module 4 has protruding fixing parts 441 at both ends along the second direction Y1. Each fixing part 441 is fixedly connected to the structural member 31 to fix the pressure-sensitive module 4 to the structural member 31. With this structure, the pressure-sensitive module 4 is fixedly connected to the structural member 31 through the fixing parts 441, which can ensure the reliability of the pressure-sensitive module 4 in the housing 1. Moreover, compared with the method of fixing the pressure-sensitive module 4 by adhesive (e.g., adhesive backing), the dispersion and absorption of the pressing pressure caused by the adhesive material can be reduced, thereby reducing the loss of pressing pressure, so that the user can trigger the function by pressing the button 3 lightly.

[0186] In one example, such as Figure 5a , Figure 11 As shown, when the pressure-sensitive module 4 has protruding fixing parts 441 at both ends (i.e., the first end 42 and the second end 43) along the second direction Y1, the fixing parts 441 protrude outward from the end face of the bracket 44 along the second direction Y1. In this way, the fixing parts 441 are formed by the two ends of the bracket 44 protruding outward in the second direction Y1, which not only makes the bracket 44 structurally stable, but also enhances the connection strength between the bracket 44 and the structure.

[0187] It should be noted that the fixing part 441 and the bracket 44 can be an integral structure or a separate structure, and the embodiments of this application do not limit this.

[0188] Specifically, in one possible implementation, such as Figure 4 , Figure 5a and Figure 11As shown, a protruding mounting platform 312 is provided on the first surface 311 of the structural member 31 in the area corresponding to the fixing part 441. In the second direction Y1, the mounting platform 312 is located outside the pressure-sensitive module 4 and is spaced apart from the end face of the corresponding end of the pressure-sensitive module 4. The fixing part 441 is fixedly connected to the mounting platform 312, so as to be fixedly connected to the structural member 31 through the mounting platform 312. With this structure, the mounting platform 312 is provided on the structural member 31, thereby stably fixing the pressure-sensitive module 4 to the structural member 31, which helps to ensure the structural reliability of the button assembly 2 during the pressing process.

[0189] Furthermore, such as Figure 5a As shown, the fixing part 441 and the mounting platform 312 are stacked on top of each other in the first direction X1.

[0190] In one possible implementation, such as Figure 5a and Figure 5b As shown, the fixing part 441 is fixedly connected to the structural component 31 by a thread. That is, the fixing part 441 is threaded to the mounting platform 312 by a fastener 45. At this time, the pressure-sensitive module 4 is easy to disassemble and reassemble, and convenient for maintenance and component replacement.

[0191] In another possible implementation, the fixing part 441 and the structural member 31 are fixedly connected by a snap-fit ​​mechanism. Specifically, as shown below... Figure 15 As shown, the mounting platform 312 is provided with a slot 3121, and the fixing part 441 is engaged with the slot 3121. In this way, the button assembly 2 can be quickly assembled during the installation process, and the manufacturing cost is low.

[0192] In another possible implementation, the fixing part 441 and the structural member 31 are fixedly connected by welding. That is, as... Figure 16 As shown, the fixing part 441 is welded to the surfaces opposite to the mounting platform 312. This provides a reliable connection and a waterproof / dustproof seal at the fixing point, with a simple process and easy manufacturing. Specifically, both sides of the fixing part 441 opposite to each other in the first direction X1 can be welded to the inner surface of the mounting platform 312 and the surfaces of other components inside the electronic device 100, ensuring that the pressure-sensitive module 4 is firmly fixed inside the electronic device 100 and guaranteeing reliable operation.
