Description

Technical Field

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

[0002] With the development of technology, various terminal products such as mobile phones and tablets are being updated and replaced very quickly, and the market has increasingly higher requirements for the performance of mobile phones, tablets and other electronic devices.

[0003] In electronic devices (such as mobile phones or tablets), buttons (e.g., volume buttons or power buttons) are used more and more frequently. However, existing buttons are prone to becoming unresponsive or lacking sufficient rebound force during frequent use, affecting the user experience. Utility Model Content

[0004] This application provides an elastic bracket for buttons, buttons, and electronic devices, which can improve the sensitivity and rebound force of electronic device buttons, resulting in a better user experience.

[0005] A first aspect of this application provides a resilient support for a button, the resilient support being disposed between the button's keycap and a switch. The resilient support includes a resilient support body and a rigid member. The resilient support body includes a trigger portion for pressing the trigger area of ​​the switch. The rigid member and the trigger portion are stacked in a first direction, and the rigid member is fixedly connected to a first side of the trigger portion, the first side being the side of the trigger portion facing the switch in the first direction.

[0006] When the trigger part is subjected to pressing pressure along the first direction, the elastic support body undergoes elastic deformation, causing the trigger part and the rigid component to move in the direction of the switch in the first direction and press the trigger area of ​​the switch, and the rigid component contacts the trigger area of ​​the switch.

[0007] The elastic support provided in this embodiment includes a rigid component located between the trigger portion and the switch of the elastic support body, and fixed on the side of the trigger portion facing the switch. During button pressing, the pressing force is transmitted from the keycap to the elastic support body, then through the trigger portion to the rigid component. The rigid component evenly and quickly transmits the pressing force to the trigger area of ​​the switch, thereby triggering the switch. When the button is released, the switch transmits its own elastic deformation-generated rebound force to the rigid component, which then transmits the rebound force to the elastic support body. The elastic support body itself also has a rebound force, and the elastic support body uses its own rebound force and the rebound force transmitted from the rigid component together to push the keycap back to its original position.

[0008] Because rigid components generally have a high elastic modulus, their deformation is small. Since the rigid component is in direct contact with the switch's trigger area, even if the elastic support body undergoes non-linear deformation during the force transmission process, the rigid component can receive the uneven pressing force transmitted from the elastic support body and then distribute the pressing force more evenly to the switch's trigger area. This avoids the drawback of the elastic support body, made of soft material and in direct contact with the switch's trigger area, collapsing due to non-linear deformation, failing to effectively transmit the received pressing force to the switch's trigger area, and thus failing to trigger the switch. Therefore, the trigger sensitivity of the button is improved, thereby enhancing the performance of the electronic device.

[0009] When the keycap is released, the switch has a rebound force. Because the deformation of the rigid component is small, the rigid component can also evenly transmit the rebound force of the switch to the elastic support body, thereby improving the rebound force of the key and its rebound rate.

[0010] The reason why rigid components can quickly convert uneven pressing pressure into uniform pressing pressure is as follows: Due to the high elastic modulus of rigid components, stress can be rapidly transferred through interatomic forces. When a rigid component is subjected to localized stress, stress waves propagate rapidly within the component, causing stress to diffuse quickly. On the other hand, the high resistance to deformation of rigid components limits large local deformations, forcing stress to be distributed more evenly across the entire cross-section to avoid localized stress overload. Therefore, when a rigid component is subjected to uneven pressing pressure on one side along its thickness direction, the uneven pressing pressure diffuses rapidly within the component, resulting in a uniform pressing pressure output on the other side.

[0011] Therefore, the elastic support for buttons provided in this application embodiment, after adding rigid components, can effectively improve the trigger sensitivity and rebound force of the buttons, as well as the rebound rate of the buttons, and also help improve the user's pressing feel, resulting in a better user experience.

[0012] In one possible implementation, when the trigger part and the rigid component press the trigger area of ​​the switch, the trigger part does not contact the trigger area of ​​the switch.

[0013] By adopting the above solution, since the trigger part does not contact the trigger area of ​​the switch, and only the rigid part contacts the trigger area of ​​the switch, the force transmission efficiency is improved, which can further improve the trigger sensitivity and rebound force of the button.

[0014] In one possible implementation, when the elastic support body is positioned between the keycap and the switch, the orthographic projection of the rigid component on the first plane completely covers the orthographic projection of the trigger area on the first plane, where the first plane is a plane perpendicular to the first direction.

[0015] By adopting the above solution, since the orthographic projection of the rigid component on the first plane safely covers the orthographic projection of the trigger area on the first plane, it can be ensured that during the key pressing or releasing process, the rigid component completely covers the entire trigger area of ​​the switch. This allows for a better and more even distribution of the pressing force of the rigid component to the switch, or a better distribution of the rebound force of the switch to the rigid component. This, in turn, improves the key's trigger sensitivity and rebound force, thus enhancing the user's pressing feel. Furthermore, it reduces the phenomenon of poor switch triggering caused by contact misalignment between the rigid component and the switch. Contact misalignment refers to the misalignment between the keycap, the trigger part of the elastic support body, and the trigger area of ​​the switch due to creep or permanent deformation of the elastic support body after long-term use.

[0016] In one possible implementation, the orthographic projection of the first side of the trigger portion onto the first plane completely covers the orthographic projection of the rigid component onto the first plane, where the first plane is a plane perpendicular to the first direction.

[0017] By adopting the above solution, the first side of the trigger completely covers the rigid component, which can better transmit the pressing force of the trigger to the rigid component and then evenly to the switch. Alternatively, it can better transmit the rebound force of the switch to the trigger through the rigid component, thereby improving the trigger sensitivity and rebound force of the button and enhancing the user's pressing feel. Furthermore, it can reduce the phenomenon of poor switch triggering caused by misalignment between the trigger and the rigid component.

[0018] In one possible implementation, the first side portion includes a first side surface that faces the switch in a first direction. A rigid member is disposed on the first side surface; alternatively, the first side portion has a groove recessed from the first side surface along the first direction toward the interior of the trigger portion, and the rigid member is embedded in the groove.

[0019] In one possible implementation, the rigid component is bonded and fixed to the first side of the trigger portion, or the elastic support body is integrally formed on the outer surface of the rigid component by injection molding, so that the first side of the trigger portion is fixedly connected to the rigid component.

[0020] In one possible implementation, the elastic bracket body further includes an elastic connecting portion and a fixing portion. A first end of the elastic connecting portion is connected to the outer peripheral surface of the trigger portion, and a second end of the elastic connecting portion is further away from the trigger portion than the first end in a plane perpendicular to the first direction. The fixing portion is connected to the second end of the elastic connecting portion for fixing the elastic bracket into the housing of the electronic device.

[0021] When the trigger part is pressed along the first direction, the elastic connecting part undergoes elastic deformation, causing the trigger part and the rigid part to move in the direction of the switch in the first direction and press the trigger area of ​​the switch. After the pressing pressure is removed, the trigger part is driven to spring back to the initial position under the action of the elastic force of the switch and the elastic connecting part.

[0022] In one possible implementation, the elastic connection portion extends from its first end to its second end in a direction away from the outer periphery of the trigger portion on a plane perpendicular to the first direction, and in a direction closer to the switch in the first direction.

[0023] In one possible implementation, in a first direction, a first side of the trigger portion protrudes from a surface of the elastic connection portion facing the switch.

[0024] With the above solution, the first side of the trigger portion protrudes from the surface of the elastic connection portion facing the switch. This means there is a protrusion on the surface of the trigger portion facing the switch. This protrusion enables precise force transmission, mechanical positioning and guidance, and reduces fatigue of soft materials. Specifically, the protrusion concentrates the force applied by the user pressing the keycap to the rigid component, avoiding pressure dispersion caused by elastic deformation of the elastic connection portion, thus achieving precise force transmission. Simultaneously, the protrusion physically abuts against the rigid component, ensuring vertical alignment accuracy with each press and preventing poor contact due to deformation of the soft material, thereby improving mechanical positioning and guidance. Finally, the protrusion undertakes the main pressure transmission task, reducing the deformation of the elastic support body, thereby delaying aging and cracking caused by repeated compression of the elastic support body, and reducing deformation fatigue of the elastic support body.

[0025] In one possible implementation, the hard component is a hard sheet or a hard block.

[0026] In one possible implementation, the main body of the elastic support is made of soft rubber, and the rigid components are made of metal or non-metal sheets.

[0027] In one possible implementation, the thickness of the hard component is 0.05mm-0.2mm.

[0028] A second aspect of this application provides a button, including: a keycap, a switch, and an elastic bracket provided by the first aspect of this application and any possible implementation thereof. The elastic bracket is disposed between the keycap and the switch. When the keycap is pressed, it pushes the trigger portion and rigid member of the elastic bracket to move towards the switch, pressing the trigger area of ​​the switch to trigger the switch.

[0029] In the button provided in this application, the elastic bracket provided by the first aspect and any possible implementation thereof ensures that the rigid part of the elastic bracket and the trigger area of ​​the switch are in hard contact during the pressing of the button cap. This avoids the disadvantage of the elastic bracket body collapsing due to nonlinear deformation, which would prevent the switch from being triggered. In this way, the trigger sensitivity of the button can be improved.

[0030] When the keycap is released, the rigid component can evenly transmit the rebound force of the switch to the elastic support body, thereby improving the rebound force and rebound rate of the key, which helps to improve the user's pressing feel.

[0031] In one possible implementation, there is rigid contact between the rigid component and the trigger area of ​​the switch. This improves the force transmission efficiency between the rigid component and the trigger area of ​​the switch, allowing for more effective switch activation when the keycap is pressed and more efficient transmission of the switch's rebound force to the rigid component when the keycap is released, thus pushing the keycap back to its initial position. Therefore, this further improves the key's trigger sensitivity and rebound force, increases the key's rebound rate, and enhances the user's tactile feedback, resulting in a better user experience.

[0032] In one possible implementation, along a first direction, the keycap and the switch are disposed opposite each other on both sides of the elastic bracket, the keycap abuts against the second side of the trigger portion, and the second side is disposed opposite to the first side in the first direction.

[0033] In one possible implementation, the keycap includes a cap body and a guide rod, which is disposed between the cap body and a resilient support along a first direction. The guide rod is axially aligned with the first direction, with one end connected to or abutting against the cap body and the other end abutting against a second side of the trigger portion of the resilient support. The second side is positioned opposite to the first side in the first direction. A sealing ring is fitted onto the outer circumferential surface of the guide rod, and a sealing connection is formed between the guide rod and the inner circumferential surface of the sealing ring.

[0034] By adopting the above scheme, the guide rod can guide the pressing and rebounding directions of the cap body, thereby improving the force transmission efficiency of pressing and rebounding.

[0035] In one possible implementation, the switch has a protrusion on the side facing the rigid component, which serves as a trigger area. The protrusion is used to abut against the rigid component after the elastic support is pressed.

[0036] By adopting the above solution, since the switch also has a protrusion, it is similar to setting a protrusion on the main body of the elastic bracket, and can also achieve precise force transmission, mechanical positioning and guidance.

[0037] In one possible implementation, the protrusion is formed on the top cover or metal spring of the switch.

[0038] In one possible implementation, the button further includes a fixing bracket, to which the fixing part of the elastic bracket body is fixedly connected, and the switch is fixed to the fixing bracket. The fixing bracket is used to fix the elastic bracket and the switch inside the housing of the electronic device.

[0039] A third aspect of this application also provides an electronic device, including a housing and a button provided by the second aspect of this application and any possible implementation thereof. The button is mounted on the housing, with a portion of the keycap structure at the end furthest from the switch exposed outside the housing, and a flexible support and the switch located inside the housing.

[0040] When the button on an electronic device is pressed, it can prevent the elastic support body from collapsing locally due to nonlinear deformation, thus avoiding the drawback of not being able to trigger the switch. It can improve the trigger sensitivity of the button, thereby improving the performance of the electronic device.

[0041] When the keycap is released, the rigid components can also evenly transmit the rebound force of the switch to the elastic support body, thereby improving the rebound force of the key and the rebound rate of the key, which in turn improves the performance of the electronic device.

[0042] In one possible implementation, the housing includes a middle frame, with a first mounting groove and a second mounting groove formed on the edge of the middle frame. The first mounting groove is recessed inward from the outer side of the edge, and the second mounting groove is located inside the edge. A guide hole is formed at the bottom of the first mounting groove, and the end of the guide hole away from the first mounting groove communicates with the second mounting groove. The keycap body is slidably connected to the first mounting groove, and a portion of the keycap body extends out of the first mounting groove and is exposed outside the housing. The keycap guide post is slidably connected to the guide hole, and the elastic bracket and switch are located in the second mounting groove. Attached Figure Description

[0080] To facilitate understanding of the plan, some terms will be explained below:

[0081] Elastic modulus is a physical quantity that describes a material's ability to resist deformation during its elastic deformation phase. It is defined as the ratio of stress (σ) to strain (ε) within the elastic limit of the material, i.e., E = σ / ε, where E is the elastic modulus value. The larger the elastic modulus, the more difficult it is for the material to undergo elastic deformation under stress (i.e., the stronger its rigidity). In other words, the elastic modulus of rigid materials is much higher than that of soft materials; for example, the elastic modulus of steel is much higher than that of silicone.

[0082] Poisson's ratio is a parameter in mechanics of materials used to describe the proportional relationship between lateral deformation and axial deformation when a material is subjected to uniaxial tension or compression.

[0083] To make the objectives, technical solutions, and advantages of this application clearer, the relevant technologies of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0084] In electronic devices (such as mobile phones or tablets), buttons (e.g., volume buttons or power buttons) are used more and more frequently. However, some buttons are prone to becoming unresponsive or lacking sufficient rebound force during frequent use, affecting the user experience. To illustrate this issue more clearly, the following analysis uses the structure of a button in an electronic device as an example.

[0085] Please see Figure 1 , Figure 1 This is a schematic diagram of a partial structure of the area where a button is located in an electronic device.

[0086] like Figure 1 As shown, the electronic device 100' includes a housing 1' and a button 4' mounted on the housing 1'. The button 4' includes a keycap 5', a spring bracket 6', and a switch 7' arranged sequentially. The spring bracket 6' has a trigger portion 610' for pressing the switch 7'. When the keycap 5' is pressed, it pushes the keycap 5' along... Figure 1 Move the keycap 5' in the direction indicated by the middle arrow, pressing the trigger part 610' of the elastic bracket 6'. The elastic deformation of the elastic bracket 6' itself causes the trigger part 610' to press the trigger area of ​​the switch 7', thus triggering the switch 7'. When the keycap 5' is released, both the switch 7' and the elastic bracket 6' will generate a rebound force, thereby pushing the keycap... Figure 1 Move in the opposite direction of the arrow, and keycap 5' returns to its initial position.

[0087] However, during the pressing or rebounding process of the aforementioned keycaps, because the elastic bracket is made of soft rubber (e.g., silicone), and the trigger part of the elastic bracket directly contacts the trigger area of ​​the switch, and the contact between the two is a soft contact, the force transmission efficiency between the elastic bracket and the switch is low, which can cause trigger failure or poor rebound, affecting the user's interactive experience.

[0088] The following is an analysis of the reasons for the poor force transmission efficiency between the elastic support and the switch.

[0089] The elastic modulus of soft rubber materials is typically low (e.g., generally 1 MPa to 10 MPa). Since the elastic modulus is equal to the ratio of stress (σ) to strain (ε), when the stress is constant, the lower the elastic modulus, the greater the strain (i.e., elastic deformation) of the material. Under pressure, soft rubber is prone to large deformation, which easily triggers volume compression. Volume compression refers to specific phenomena or changes caused by volume compression. Since the Poisson's ratio of soft rubber (e.g., silicone) is close to 0.5, a Poisson's ratio of 0.5 indicates that the soft rubber is an approximately incompressible material. When soft rubber is under pressure, its lateral expansion is restricted, resulting in a complex stress distribution within the soft rubber, further leading to nonlinear deformation within the soft rubber.

[0090] Therefore, because the trigger part of the elastic bracket (made of soft material) is in direct contact with the trigger area of ​​the switch, and the contact between the elastic bracket and the switch is a soft contact, the elastic bracket is prone to non-linear deformation when the keycap presses the elastic bracket or when the switch provides a rebound force to the elastic bracket. This non-linear deformation leads to uneven pressure distribution, with some areas deforming excessively while others do not reach the trigger stroke. This causes localized collapse of the trigger part of the elastic bracket, resulting in low force transmission efficiency between the elastic bracket and the switch. It fails to effectively transmit the pressing force on the trigger part of the elastic bracket to the trigger area of ​​the switch, or fails to effectively transmit the rebound force of the switch to the trigger part, easily leading to trigger failure or poor rebound, thus affecting the user's interactive experience.

[0091] It is evident that some button designs are prone to becoming unresponsive or lacking sufficient rebound force during frequent use, thus affecting the user experience.

[0092] To address the aforementioned issues, this application provides an elastic support for a button. The elastic support has a rigid component that directly contacts the trigger area of ​​the switch. After receiving uneven pressing pressure from the elastic support body, the rigid component rapidly diffuses the pressure within itself and then evenly transmits it to the trigger area of ​​the switch. This results in high force transmission efficiency between the elastic support and the switch, preventing uneven pressure distribution caused by localized collapse of the soft material, which could lead to poor switch triggering. Therefore, this application effectively improves the button's trigger sensitivity and rebound force, as well as its rebound rate, and enhances the user's pressing feel and interactive experience.

[0093] This application also provides a button. By applying this elastic bracket, the button's trigger sensitivity and rebound force can be effectively improved, as well as the button's rebound rate. It also helps to improve the user's pressing feel, resulting in a better user experience.

[0094] This application provides an electronic device that uses the aforementioned buttons. The electronic device may include, but is not limited to, mobile terminals, fixed terminals, or foldable terminals with buttons, such as mobile phones, tablets, laptops, wearable smartwatches, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), dashcams, and security equipment.

[0095] In this embodiment, a mobile phone is used as an example to specifically describe the structure and function of the electronic device. Of course, the mobile phone can be a foldable phone or a candybar phone. Among them, the foldable phone can be an inward-folding phone or an outward-folding phone.

[0096] Please see Figures 2a-2e , Figure 2a This is a three-dimensional structural diagram of the electronic device according to an embodiment of this application. Figure 2b This is an exploded structural diagram of the electronic device according to an embodiment of this application. Figure 2c This is a schematic diagram of the back of the electronic device according to an embodiment of this application (the back cover has been removed from the figure). Figure 2d A cross-sectional schematic diagram of an electronic device according to an embodiment of this application. Figure 1 . Figure 2e This is a second cross-sectional schematic diagram of the electronic device according to an embodiment of this application. It should be noted that the accompanying drawings of this embodiment are for illustrative purposes only, and the size and positional relationship of the components in the drawings do not represent the size and positional relationship of the components in the actual product. The electronic device may also include more or fewer components than shown in the drawings, and this embodiment does not impose any limitations on this.

[0097] like Figures 2a-2c As shown, the electronic device 100 includes a housing 1 and a display screen 21. 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 within the electronic device 100. The display screen 21 is disposed within the housing space and connected to the housing 1. The specific structure of the housing 1 will be described later in conjunction with the accompanying drawings.

[0098] Specifically, the display screen 21 is used to display images. The display screen 21 may be, but is not limited to, an organic light-emitting diode (OLED) display screen 21, an active-matrix organic light-emitting diode (AMOLED) display screen 21, or a quantum dot light-emitting diode (QLED) display screen 21, etc. The embodiments of this application do not limit the type and specific structure of the display screen 21.

[0099] like Figure 2b As shown, the electronic device 100 may further include a battery 22 and a circuit board 3 (e.g., a first circuit board 31 and a second circuit board 32) installed within the housing 1. The battery 22 is a functional device that supplies power to the various electronic components in the electronic device 100, and it is typically connected to the circuit board 3. The battery 22 may be, for example, a lithium-ion battery 22, a nickel-cadmium battery 22, a nickel-metal hydride battery 22, etc., and the specific type is not limited in this embodiment.

[0100] It should be noted that the number of circuit boards 3 within the electronic device 100 is unlimited. In one possible implementation, such as... Figure 2b and Figure 2cAs shown, the electronic device 100 includes a first circuit board 31 and a second circuit board 32. The first circuit board 31 is the motherboard, mainly responsible for the calculation of most system functions. Electronic components, such as a camera compact module (CCM), a system-on-chip (SOC), a wireless Fidelity (Wi-Fi) module, and a power management unit (PMU), can be mounted on the first circuit board 31. The second circuit board 32 is a secondary board, mainly responsible for auxiliary functions such as audio signal transmission and signal connection processing. In other possible implementations, the first circuit board 31 can also be a secondary board, and the second circuit board 32 can be the motherboard; this embodiment does not limit this. Furthermore, the type of circuit board 3 is not limited; for example, it can be a PCB (printed circuit board).

[0101] For ease of understanding, such as Figures 2a to 2e As shown, the X direction is defined as the width direction X of the electronic device, the Y direction as the length direction Y of the electronic device, and the Z direction as the thickness direction Z of the electronic device.

[0102] The above mainly introduced the possible basic structure of the electronic device 100. The following text will describe the specific structure of the housing 1.

[0103] It will be understood by those skilled in the art that the specific structure of the housing 1 is not limited. For example... Figure 2a and Figure 2b As shown, in one possible implementation, the housing 1 includes a middle frame 11, which includes a middle plate 112 and a frame 111 connected to the outer periphery of the middle plate 112. The middle plate 112 supports the display screen 21 and the internal components of the electronic device 100. The frame 111 is a frame structure surrounding the outer periphery of the electronic device 100. The frame 111 may include four sides surrounding the display screen 21: a top frame 1114, a bottom frame 1115, a left frame 1116, and a right frame 1117. The top frame 1114, bottom frame 1115, left frame 1116, and right frame 1117 form an annular frame 111 to help fix the display screen 21. In other possible implementations, the frame 111 may also include only three sides, two sides, etc., and this embodiment does not limit this. The frame 111 may be formed of a conductive material such as metal or a non-conductive material such as plastic.

[0104] It should be noted that the top border 1114 of the middle frame 11 is the side where the top of the middle frame 11 is located when the user uses the electronic device 100; the bottom border 1115 of the middle frame 11 is the side where the bottom of the middle frame 11 is located when the user uses the electronic device 100; the left border 1116 of the middle frame 11 is the side where the left side of the middle frame 11 is located when the user uses the electronic device 100; and the right border 1117 of the middle frame 11 is the side where the right side of the middle frame 11 is located when the user uses the electronic device 100. In one example, in the length direction Y of the electronic device, the top border 1114 and the bottom border 1115 are set opposite to each other, and in the width direction X of the electronic device, the left border 1116 and the right border 1117 are set opposite to each other in the width direction X of the electronic device. It should be understood that, in the embodiments of this application, when a user holds the electronic device 100 (for example, when the user holds the electronic device 100 and unlocks it, or for example, when the user holds the electronic device 100 vertically and faces the display screen 21), the orientation of the electronic device 100 has a top, bottom, left side and right side.

[0105] Furthermore, such as Figure 2b and Figure 2c As shown, the housing 1 may also include a back cover 12, also known as a battery cover, which is located on the back of the electronic device 100. The back cover 12, the mid-frame 11, and the display screen 21 together form a housing space to enclose electronic components such as the battery 22 and the circuit board 3 inside the electronic device 100, while also protecting against dust, impacts, and scratches.

[0106] It should be noted that the back cover 12 can be a back cover made of metal; it can also be a back cover made of non-conductive material, such as a glass back cover, a plastic back cover, or other non-metallic back covers; or it can be a back cover made of both conductive and non-conductive materials.

[0107] In one possible implementation, such as Figure 2d As shown, the middle plate 112 can also be spaced apart from the rear cover 12, meaning the middle plate 112 and the rear cover 12 are independently configured. Specifically, in the thickness direction Z of the electronic device, the rear cover 12 is connected to one side of the frame 111, the middle plate 112 can be positioned in the middle of the frame 111, and the display screen 21 and the rear cover 12 are respectively mounted on both sides of the middle plate 112. In this way, both the middle plate 112 and the rear cover 12 can mount components, providing more mounting space for electronic components. For example, Figure 2d As shown, the battery 22 can be disposed between the middle plate 112 of the middle frame 11 and the back cover 12, or, as... Figure 2e As shown, the battery 22 can be disposed between the middle plate 112 of the middle frame 11 and the display screen 21, but this embodiment does not limit this.

[0108] It should be noted that the connection method between the middle frame 11 and the back cover 12 is not limited in the embodiments of this application. In one example, the middle frame 11 and the back cover 12 are manufactured by integral molding or assembled by permanent connection methods such as welding.

[0109] In one possible implementation, such as Figure 2b As shown, the middle plate 112 of the middle frame 11 is reused as the back cover 12. Specifically, in the thickness direction Z of the electronic device, the display screen 21 is mounted on one side of the frame 111, and the middle plate 112 is connected to the other side of the frame 111 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 structure" in cross-section. In this way, the middle plate 112 simultaneously performs the functions of both the middle plate 112 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.

[0110] 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 112 and the frame 111 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 112 and the frame 111 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.

[0111] The above mainly provides an exemplary description of the structure of housing 1. The following section will provide a detailed description of the basic structure of button 4 and the way button 4 and housing 1 are matched, with reference to the accompanying drawings.

[0112] Please see Figures 3a to 3d , Figure 3a This is a schematic diagram of one embodiment of a button in an electronic device according to this application. Figure 3b for Figure 3a A magnified view of a portion of the image; Figure 3c This is a schematic diagram illustrating another implementation of the button in the embodiments of this application; Figure 3d This is a schematic diagram of another embodiment of the button in this application.

[0113] like Figure 2c and Figure 3a As shown, the electronic device 100 may also include a button 4, which is mounted on the housing 1. Part of the button 4 is exposed outside the housing 1, while another part is located inside the housing 1. By pressing the exposed portion of the button 4, the switch 7 of the button 4 can be triggered to generate a trigger signal, thereby controlling some functions of the electronic device 100.

[0114] The specific type of button 4 is not limited; for example, it may include, but is not limited to, a power button, volume buttons, etc. Button 4 may be a mechanical button. Electronic device 100 can receive input from button 4 and generate key signal inputs related to user settings and function control of electronic device 100.

[0115] like Figure 2c As shown, in one possible implementation, button 4 can be electrically connected to the first circuit board 31 (i.e., the motherboard) of electronic device 100, so that button 4 can control some functions of electronic device 100, such as adjusting the volume of electronic device 100, or controlling the display screen 21 of electronic device 100 to turn on or off. In other possible implementations, button 4 can also be electrically connected to electronic devices, which is not limited in this embodiment.

[0116] It should be noted that the location of button 4 on housing 1 is not limited. In one possible implementation, such as... Figure 2c and Figure 3a As shown, button 4 is disposed on the edge 111 of the middle frame 11. Part of the structure of button 4 is exposed outside the edge 111, and another part of the structure is disposed inside the middle frame 11. Specifically, a first mounting groove 1111 is formed on the edge 111. The first mounting groove 1111 is recessed inward from the outer side of the edge 111. Part of the structure of button 4 is installed in the first mounting groove 1111 and extends out of the first mounting groove 1111, and is exposed outside the edge 111 of the middle frame 11.

[0117] like Figure 2c As shown, in one example, button 4 is located on the right side border 1117 of border 111, that is, on the side along the length direction Y of the electronic device. Of course, in other examples, button 4 can also be located on the left side border 1116 of border 111, or on the top border 1114 or bottom border 1115, that is, on the side along the width direction X of the electronic device.

[0118] The above mainly describes the function and location of button 4 in detail. The following text will elaborate on the basic structure and working principle of button 4.

[0119] like Figure 3a As shown, button 4 includes a keycap 5, a spring-loaded bracket 6, and a switch 7, with the spring-loaded bracket 6 disposed between the keycap 5 and the switch 7. The keycap 5 is mounted on the housing 1 (e.g., the frame 111 of the middle frame 11), and a portion of the keycap 5 away from the switch 7 is exposed outside the housing 1. The spring-loaded bracket 6 and the switch 7 are located inside the housing 1 (e.g., inside the frame 111 of the middle frame 11). In one example, the keycap 5 is slidably connected within a first mounting groove 1111, and a portion of the keycap 5 extends out of the first mounting groove 1111 and is exposed outside the housing 1.

[0120] When keycap 5 is pressed, keycap 5 along... Figure 3a Move and press the elastic bracket 6 in the direction indicated by the middle arrow. The elastic deformation of the elastic bracket 6 causes a portion of its structure to press the trigger area 71 of the switch 7 along the first direction P, thereby triggering the switch 7. The internal circuit of the switch 7 is then activated, for example, sending an electrical signal to the motherboard of the electronic device 100. The motherboard then controls other electronic components of the electronic device 100 to perform corresponding functions. When the keycap 5 is released, both the switch 7 and the elastic bracket 6 generate a rebound force in the first direction P, thereby pushing the keycap 5 towards... Figure 3a Move the keycap in the opposite direction of the arrow to return it to its initial position (i.e., reset).

[0121] It should be noted that the first direction P can be understood as the direction in which the elastic bracket 6 presses the switch 7, or as the direction in which the switch 7 rebounds and the elastic bracket 6 rebounds.

[0122] like Figure 2c and Figure 3a As shown, the direction of movement of the keycap 5 can be the same as or different from the first direction P. In one example, the direction of movement of the keycap 5 is the same as the first direction P. Along the first direction P, the keycap 5 and the switch 7 are disposed opposite each other on both sides of the elastic support 6, and the keycap 5 abuts against a portion of the structure of the elastic support 6 (e.g., the trigger portion 610 mentioned below). When the keycap 5 is pressed, it can push that portion of the structure of the elastic support 6 (e.g., the trigger portion 610) towards the switch 7, triggering the switch 7.

[0123] Furthermore, when the keycap 5 is installed on the left side 1116 or right side 1117 of the frame 111, the moving direction of the keycap 5 is the width direction X of the electronic device, and the first direction P is also the width direction X of the electronic device. When the keycap 5 is installed on the top side 1114 or bottom side 1115 of the frame 111, the moving direction of the keycap 5 is the length direction Y of the electronic device, and the first direction P is also the length direction Y of the electronic device.

[0124] In other examples, the direction of movement of keycap 5 is perpendicular to the first direction P. For example, when the direction of movement of keycap 5 is the width direction X of the electronic device, the first direction P is also the length direction Y or the thickness direction of the electronic device.

[0125] The following provides a detailed description of the specific structure of the elastic support 6 in the embodiments of this application. It should be noted that the elastic support 6 in the embodiments of this application can be applied to... Figure 3aThe button 4 shown can also be applied to other types of buttons 4. The application scenario of the elastic bracket 6 is not limited here.

[0126] like Figures 3a-3b As shown, the elastic support 6 includes an elastic support body 61 and a rigid component 62. The elastic support body 61 includes a trigger portion 610, which is used to press the trigger area 71 of the switch 7. The rigid component 62 is stacked on top of the trigger portion 610 in a first direction P, and the rigid component 62 is fixedly connected to the first side portion 6101 of the trigger portion 610. Specifically, the first side portion 6101 is the side portion of the trigger portion 610 facing the switch 7 in the first direction P. When the trigger portion 610 is subjected to a pressing force along the first direction P, the elastic support body 61 undergoes elastic deformation, causing the trigger portion 610 and the rigid component 62 to move in the direction of the switch 7 in the first direction P, pressing the trigger area 71 of the switch 7 to trigger the switch 7, and the rigid component 62 contacts the trigger area 71 of the switch 7. It should be noted that the first direction P can be the thickness direction of the trigger portion 610 or the thickness direction of the rigid component 62. The rigid component 62 can be understood as a structural component made of a rigid material.

[0127] When the trigger portion 610 of the elastic support 6 is pressed, the elastic support 6 elastically deforms towards the switch 7, and the rigid member 62 can press the trigger area 71 of the switch 7. Additionally, when the switch 7 is a switch with a spring-loaded capability, the spring-loaded force of the switch 7 is transmitted to the rigid member 62. The elastic support body 61 resets itself using its own spring-loaded force and the spring-loaded force transmitted from the switch 7. During the reset process of the elastic support body 61, the keycap 5 is also pushed to reset. It should be noted that if the switch 7 is not a switch with a spring-loaded capability, the keycap 5 can be pushed to reset using the spring-loaded force of the elastic support body 61 itself.

[0128] The elastic support body 61 provided in this embodiment includes a rigid component 62, which is located between the elastic support body 61 and the switch 7, and fixed to the trigger portion 610 of the elastic support body 61 facing the switch 7. During the pressing of the key 4, the pressing force is transmitted from the keycap 5 to the elastic support body 61, and then through the elastic support body 61 to the rigid component 62. The rigid component 62 evenly and quickly and effectively transmits the pressing force to the trigger area 71 of the switch 7, thereby triggering the switch 7. When the key 4 is released, the switch 7 transmits the rebound force to the rigid component 62, and the rigid component 62 transmits the rebound force to the elastic support body 61. The elastic support body 61 itself also has a rebound force, and the elastic support body 61 uses its own rebound force and the rebound force transmitted from the rigid component 62 together to push the keycap 5 back to its original position.

[0129] Because the rigid component 62 has a large elastic modulus (for example, the elastic modulus can be greater than or equal to 1 GPa), the deformation of the rigid component 62 is small. Furthermore, the rigid component 62 is in direct contact with the trigger area 71 of the switch 7, resulting in high force transmission efficiency between the elastic support 6 and the switch 7. During this force transmission process, even if the elastic support body 61 undergoes nonlinear deformation, the rigid component 62 can accept the uneven pressing pressure transmitted from the elastic support body 61 and then evenly transmit the pressing pressure to the switch 7. This avoids the drawback of the elastic support body 61 failing to effectively transmit the received pressing pressure to the trigger area of ​​the switch due to local collapse, thus preventing the switch 7 from being triggered. Therefore, the trigger sensitivity of the button 4 is improved, thereby enhancing the performance of the electronic device 100.

[0130] When keycap 5 is released, switch 7 has a rebound force. Since the deformation of rigid component 62 is small, rigid component 62 can also evenly transmit the rebound force of switch 7 to elastic support body 61, thereby improving the rebound force of key 4 and also improving the rebound rate of key 4.

[0131] The reason why the rigid component 62 can quickly convert uneven pressing force into uniform pressing force is as follows: Due to the high elastic modulus of the rigid component 62, stress can be quickly transferred through interatomic forces. When the rigid component 62 is locally stressed, stress waves propagate rapidly within the rigid component 62, causing stress to diffuse rapidly. On the other hand, the high resistance to deformation of the rigid component 62 limits large local deformation, forcing the stress to be distributed more evenly across the entire cross-section to avoid local stress overload. Therefore, when the rigid component 62 is subjected to uneven pressing force on one side in the thickness direction, the uneven pressing force diffuses rapidly within the rigid component 62, thereby outputting a uniform pressing force on the other side of the rigid component 62.

[0132] Therefore, after the addition of the rigid component 62, the elastic bracket 6 provided in this application embodiment can more effectively transmit the pressing force received by the trigger part 610 of the elastic bracket 6 to the trigger area 71 of the switch 7 to trigger the switch 7. It can also more effectively transmit the rebound force of the switch 7 to the trigger part 610 of the elastic bracket 6 to reset the keycap 5 to the initial position. This can effectively improve the trigger sensitivity and rebound force of the key 4, improve the rebound rate of the key 4, and help improve the user's pressing feel, resulting in a better user experience.

[0133] like Figure 3a and Figure 3bAs shown, in one possible implementation, the rigid component 62 of the elastic support 6 and the trigger area 71 of the switch 7 are in rigid contact. In this case, the trigger area 71 of the switch 7 is made of a rigid material (e.g., plastic or metal). This can more effectively improve the force transmission efficiency between the rigid component 62 and the trigger area 71 of the switch 7, thereby more effectively triggering the switch 7 when the keycap 5 is pressed, and more effectively transmitting the rebound force of the switch 7 to the rigid component 62 when the keycap 5 is released, thus pushing the keycap 5 back to its initial position. Therefore, the trigger sensitivity and rebound force of the key 4 can be further improved, as can the rebound rate of the key 4, and it helps to improve the user's pressing feel, resulting in a better user experience. In other possible implementations, the rigid component 62 of the elastic support 6 and the trigger area 71 of the switch 7 can also be in soft contact. In this case, the trigger area 71 of the switch 7 is made of a soft material (e.g., silicone or other soft rubber). This application embodiment does not limit this.

[0134] like Figure 3b As shown, in one possible implementation, when the trigger part 610 and the rigid member 62 press the trigger area 71 of the switch 7, the trigger part 610 does not contact the trigger area 71 of the switch 7. That is, it is the rigid member 62 that contacts the trigger area 71 of the switch 7. Since the trigger part 610 does not contact the trigger area 71 of the switch 7, and only the rigid member 62 contacts the trigger area 71 of the switch 7, the entire contact area between the elastic support 6 and the trigger area 71 of the switch 7 is in rigid contact, thereby improving the force transmission efficiency and further improving the trigger sensitivity and rebound force of the button 4. Of course, it should be noted that in other possible implementations, a portion of the structure around the trigger part 610 may also slightly contact the trigger area 71 of the switch 7.

[0135] In addition, to avoid poor contact of switch 7 due to contact misalignment, in some embodiments, the elastic bracket 6 can be further improved as follows. Contact misalignment refers to the fact that after long-term use of button 4, the elastic bracket body 61 (e.g., made of soft rubber) is prone to creep or permanent deformation, resulting in misalignment between keycap 5, elastic bracket body 61 and trigger area 71 of switch 7.

[0136] like Figure 3d As shown, in one possible implementation, the orthographic projection of the rigid component 62 onto the first plane S completely covers the orthographic projection of the trigger area 71 onto the first plane S, where the first plane S is a plane perpendicular to the first direction P. The first plane S can also be understood as a plane perpendicular to the thickness direction of the rigid component 62.

[0137] Since the orthographic projection of the rigid component 62 on the first plane S safely covers the orthographic projection of the trigger area 71 on the first plane S, it can be ensured that during the pressing or releasing process of the button 4, the rigid component 62 completely covers the entire trigger area 71 of the switch 7. This allows for a better and more even distribution of the pressing force of the rigid component 62 to the switch 7, or a better distribution of the rebound force of the switch 7 to the rigid component 62. Consequently, the trigger sensitivity and rebound force of the button 4 are improved, further enhancing the user's pressing feel. Furthermore, it reduces the occurrence of poor switch 7 triggering due to misalignment between the rigid component 62 and the switch 7.

[0138] Based on the same principle, such as Figures 3b to 3d As shown, the orthographic projection of the first side portion 6101 of the trigger portion 610 on the first plane S completely covers the orthographic projection of the rigid component 62 on the first plane S. Since the first side portion 6101 of the trigger portion 610 completely covers the rigid component 62 (or, as can be understood, the entire rigid component 62 is completely supported by the first side portion 6101, i.e., the outer peripheral surface 623 of the rigid component 62 does not extend beyond the outer peripheral surface of the first side portion 6101), the pressing force of the trigger portion 610 can be better transmitted to the rigid component 62, and then evenly transmitted to the switch 7 through the rigid component 62. Alternatively, the rebound force of the switch 7 can be better transmitted to the trigger portion 610 through the rigid component 62, thereby improving the trigger sensitivity and rebound force of the button 4 and enhancing the user's pressing feel. Furthermore, it also reduces the phenomenon of poor switch 7 triggering caused by contact misalignment between the trigger portion 610 and the rigid component 62.

[0139] In other possible implementations, the orthographic projection of the rigid component 62 onto the first plane S may not completely cover the orthographic projection of the trigger area 71 onto the first plane S, for example, as... Figure 3b As shown, the orthographic projection of the rigid component 62 on the first plane S covers a portion of the orthographic projection of the trigger area 71 on the first plane S. That is, the orthographic projection of the rigid component 62 on the first plane S is entirely located inside the orthographic projection of the trigger area 71 on the first plane S. Alternatively, it can be understood that the orthographic projection of the trigger area 71 on the first plane S completely covers the orthographic projection of the rigid component 62 on the first plane S. This embodiment of the application does not impose any limitations on this.

[0140] Correspondingly, in other possible implementations, the orthographic projection of the first side portion 6101 of the trigger portion 610 on the first plane S may not completely cover the orthographic projection of the rigid member 62 on the first plane S. For example, the outer peripheral surface 623 of the rigid member 62 extends out of the outer peripheral surface of the first side portion 6101.

[0141] It should be noted that the specific structural form of the rigid component 62 is not limited. In one possible implementation, such as... Figure 3a and Figure 3bAs shown, the rigid component 62 is a rigid sheet. In other possible implementations, the rigid component 62 may also be a rigid block or a rigid support, and this embodiment of the application does not limit this.

[0142] Furthermore, the specific structure of the rigid component 62 is not limited. For example... Figure 3b As shown, in one possible implementation, the rigid member 62 has a first surface 621 and a second surface 622 disposed opposite to each other along its thickness direction. The first surface 621 is used to contact the trigger area 71 of the switch 7, and the second surface 622 is connected to the trigger portion 610 of the elastic support body 6. The rigid member 62 also has an outer peripheral surface 623 that is in contact with the first surface 621 and the second surface 622.

[0143] It should be noted that the thickness of the rigid component 62 at each location can be the same or different. In one example, the thickness of the rigid component 62 at each location is the same. In this case, the first surface 621 and the second surface 622 are parallel to each other, and the outer peripheral surface 623 of the rigid component 62 is perpendicular to the first surface 621 and the second surface 622.

[0144] Furthermore, the specific thickness of the rigid component 62 is not limited. In one possible implementation, the thickness of the rigid component 62 is 0.05mm-0.2mm, ensuring sufficient rigidity and improving its force transmission efficiency. In other possible implementations, the thickness of the rigid component 62 can be less than 0.05mm or greater than 0.2mm; this embodiment does not impose any limitations on this. Additionally, at least one of the two sides of the rigid component 62 in the thickness direction is a smooth surface; in this embodiment, both sides of the rigid component 62 in the thickness direction are smooth surfaces. By setting both sides of the rigid component 62 in the thickness direction to smooth surfaces, the force transmission efficiency of pressing and rebound forces can be improved, for the following reasons:

[0145] It should be noted that the specific material of the rigid component 62 is not limited; it can be a metallic material (e.g., stainless steel) or a non-metallic material. Figure 3b As shown, in one possible implementation, the rigid component 62 can be a metal sheet, such as a stainless steel sheet, iron sheet, copper sheet, beryllium copper alloy sheet, nickel silver alloy sheet, titanium alloy sheet, etc. In other possible implementations, the rigid component 62 can also be a non-metallic sheet, such as a rigid plastic sheet. The rigid plastic can be ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), POM (polyoxymethylene, acetal), etc. The rigid component 62 can also be a ceramic sheet.

[0146] Furthermore, the material of the elastic support 6 is not limited; for example, it can be a soft material. Figure 3bAs shown, in one possible implementation, the material of the elastic support 6 can be a soft rubber, such as silicone, rubber, silicone rubber, thermoplastic polyurethane elastomer rubber (also known as thermoplastic polyurethane rubber, abbreviated as TPU), thermoplastic elastomer (TPE, also known as artificial rubber or synthetic rubber), hydrogenated nitrile rubber (HNBR), or styrene-based elastomer (SEBS), etc. Soft rubber materials have good elasticity and flexibility. When subjected to the pressing pressure applied by the keycap, the soft rubber material can undergo elastic deformation. Its structure itself is not easily cracked, resulting in high structural reliability and a long service life.

[0147] Furthermore, the method of fixing the rigid component 62 to the elastic support body 61 is not limited. For example... Figure 3b and Figure 3c As shown, in one possible implementation, the elastic support body 61 is integrally formed on the outer surface of the rigid part 62 by injection molding, so that the first side portion 6101 of the trigger portion 610 is fixedly connected to the rigid part 62. During the injection molding process of the elastic support body 61, the rigid part 62 (e.g., a metal sheet) can be placed into the mold, thereby injection molding the rigid part 62 and the elastic support body 61 together. This ensures the strong fixation between the rigid part 62 and the trigger portion 610 of the elastic support body 61, and the structure is simple and the cost is low.

[0148] In other possible implementations, the rigid component 62 can also be bonded and fixed to the trigger portion 610 of the elastic support body 61, and this application embodiment does not limit this.

[0149] Furthermore, the relative positional relationship between the trigger portion 610 of the elastic support body 61 and the rigid component 62 is not limited. For example... Figure 3b As shown, in one possible implementation, the first side portion 6101 includes a first side surface 6101A, which is disposed facing the switch 7 in a first direction P. A rigid member 62 is disposed on the first side surface 6101A, and in this case, the rigid member 62 protrudes entirely from the first side surface 6101A of the trigger portion 610.

[0150] In one possible implementation, such as Figure 3c As shown, the first side portion 6101 is provided with a groove 6101B, which is recessed from the first side portion 6101A along the first direction P toward the interior of the trigger portion 610. The rigid member 62 is embedded in the groove 6101B. Specifically, the second surface 622 of the rigid member 62 is connected to the bottom surface of the groove 6101B, and the outer peripheral surface 623 of the rigid member 62 is connected to the wall surface of the groove 6101B.

[0151] It should be noted that the rigid component 62 can be entirely located within the groove 6101B along its thickness direction. For example, the first surface 621 of the rigid component 62 may be recessed or aligned with the first side surface 6101A of the trigger portion 610. Alternatively, a portion of the rigid component 62 along its thickness direction may be located within the groove 6101B, while a portion may be located outside the groove 6101B. In this case, the first surface 621 of the rigid component 62 may protrude relative to the first side surface 6101A of the trigger portion 610.

[0152] The structure of the elastic support 6 is described below. However, it should be noted that the structure of the elastic support 6 is not limited to one specific one. The following is one possible implementation of the elastic support 6.

[0153] Please see Figures 4a to 4c , Figure 4a This is a three-dimensional structural schematic diagram of the elastic support according to an embodiment of this application. Figure 4b This is a three-dimensional structural schematic diagram of the elastic support according to another embodiment of this application. Figure 4c This is an exploded structural diagram of the elastic support according to an embodiment of this application.

[0154] like Figures 4a to 4c As shown, and in combination Figure 3a It is understood that, in one possible implementation, the elastic support body 61 may further include an elastic connecting portion 611 and a fixing portion 612. The first end 6111 of the elastic connecting portion 611 is connected to the outer peripheral surface of the trigger portion 610. In a plane perpendicular to the first direction P, the second end 61112 of the elastic connecting portion 611 is further away from the trigger portion 610 than the first end 6111. The fixing portion 612 is connected to the second end 61112 of the elastic connecting portion 611 and is used to fix the elastic support 6 to the housing 1 of the electronic device 100. It should be noted that the specific location of the trigger portion 610 in the elastic support body 61 is not limited; for example, it may be in the central region of the elastic support body 61.

[0155] When the trigger part 610 is pressed along the first direction P, the elastic connecting part 611 undergoes elastic deformation, causing the trigger part 610 and the rigid member 62 to move toward the switch 7 in the first direction P and press the trigger area 71 of the switch 7. After the pressing pressure is removed, the trigger part 610 is driven to spring back to the initial position under the action of the elastic force of the switch 7 and the elastic connecting part 611.

[0156] It should be noted that the specific shape of the elastic connecting part 611 is not limited, such as Figure 3a and Figure 4aAs shown, the elastic connection portion 611 extends from its first end 6111 to its second end 61112, gradually moving away from the outer periphery of the trigger portion 610 in a plane perpendicular to the first direction P, and gradually extending towards the switch 7 in the first direction P. That is, from... Figures 4a to 4b As can be seen, the elastic connecting part 611 is a structure that gradually narrows from the second end 61112 to the first end 6111. By adopting the above structure, the elastic support body 61 can be made to bulge outward toward the keycap 5.

[0157] In addition, the fixing part 612 is connected to other components within the electronic device 100, thereby fixing the elastic bracket 6 within the electronic device 100. The method of connecting the fixing part 612 to other components is not limited in this embodiment of the application. For example, it can be fixed by means of adhesive bonding, snap-fitting, etc.

[0158] In one possible implementation, such as Figures 4a to 4c As shown, along the first direction P, the surface of the fixing part 612 facing the switch 7 has a limiting groove 6121, which surrounds the elastic connecting part 611, and a limiting post 6122 is provided at the bottom of the limiting groove 6121. Other components within the electronic device 100 (e.g., the fixing bracket 8 mentioned later) also have structures that cooperate with the limiting groove 6121 and the limiting post 6122, and along the first direction P, the elastic bracket 6 is inserted into other components of the electronic device 100. Figure 4a As shown, along the first direction P, the surface of the fixing part 612 opposite to the switch 7 has a protrusion 6123, which elastically abuts against another component inside the electronic device 100. Therefore, the elastic bracket 6 can be fixed inside the electronic device 100 by the limiting groove 6121, the limiting post 6122 and the protrusion 6123.

[0159] In one possible implementation, along the first direction P, the first side portion 6101 of the trigger portion 610 protrudes from the surface of the elastic connection portion 611 facing the switch 7. That is, a protrusion is present on the surface of the trigger portion 610 facing the switch 7. This protrusion enables precise force transmission, mechanical positioning and guidance, and reduces fatigue of soft materials. Specifically, the protrusion concentrates the force exerted by the user pressing the keycap 5 onto the rigid component 62, avoiding pressure dispersion caused by elastic deformation of the elastic connection portion 611, thus achieving precise force transmission. Simultaneously, the protrusion physically abuts against the rigid component 62, ensuring vertical alignment accuracy with each press and preventing poor contact due to deformation of the soft material, thereby improving mechanical positioning and guidance. Finally, the protrusion undertakes the main pressure transmission task, reducing the deformation of the elastic support body 61, thereby delaying aging and cracking problems caused by repeated compression of the elastic support body 61, and reducing deformation fatigue of the elastic support body 61. Figures 4b to 4cAs can be seen, the protrusion is a cylindrical structure, which can be a cylindrical, elliptical, or square column, etc.

[0160] When keycap 5 is pressed, it abuts against the second side 6102 of trigger part 610. Keycap 5 pushes trigger part 610 towards switch 7. Trigger part 610 drives rigid part 62 to press trigger area 71 of switch 7, thereby triggering switch 7 to conduct. During this process, elastic connection part 611 deforms. When keycap 5 is released, elastic connection part 611 returns to its original position, thereby causing trigger part 610 to spring back to its initial position. The rebound force generated by elastic connection part 611 can also push keycap 5 to return to its original position.

[0161] Of course, it should be emphasized that in other possible implementations, the first side portion 6101 of the trigger portion 610 may not protrude from the surface of the elastic connection portion 611 facing the switch 7.

[0162] In one possible implementation, such as Figures 4a to 4c As shown, in order to optimize the deformation behavior of the elastic support body 61 in terms of structure, thereby improving the triggering performance and durability of the button 4, a slot 613 can also be opened on the elastic support body 61.

[0163] By setting the slot 613, the following optimization effects can be achieved: First, the slot 613, as a preset weak area, can force the elastic support body 61 to bend symmetrically along the center line when pressed, avoiding random deformation (such as unilateral collapse or twisting) caused by uneven local material thickness, thereby reducing bias-induced accidental contact; Second, the slot 613 disperses the compression deformation area of ​​the silicone, avoiding repeated maximum stress on the same position, thereby reducing fatigue of the elastic support body 61; Finally, the symmetrical deformation of the elastic support body 61 can reduce lateral pulling on the contact 75 of the switch 7, reducing the risk of displacement of the inner spring 74 of the switch 7.

[0164] Furthermore, the bottom of the slot 613 is provided with a first slot 614 and a second slot 615. Along the direction of the aforementioned center line, the first slot 614 and the second slot 615 are also symmetrically arranged.

[0165] It should be noted that the specific structure of button 4 is not limited, and the specific way in which button 4 and housing 1 cooperate is also not limited. The following will elaborate on this in conjunction with an exemplary structure.

[0166] Please see Figures 5a to 7b , Figures 5a to 5c This is a schematic diagram of the button and housing in an embodiment of this application. Figures 6a to 6b This is a three-dimensional structural diagram of the button in an embodiment of this application. Figures 7a to 7b This is a schematic diagram of different cross-sections of the button and the housing in an embodiment of this application.

[0167] like Figures 5a to 5c As shown, in one possible implementation, a second mounting groove 1112 is provided on the edge 111 of the middle frame 11. The second mounting groove 1112 is located inside the edge 111 and communicates with the first mounting groove 1111. The elastic bracket 6 and the switch 7 are located within the second mounting groove 1112. It should be noted that the orientation of the opening of the second mounting groove 1112 is not limited. In one example, the opening of the second mounting groove 1112 is positioned towards the back cover 12 in the thickness direction Z of the electronic device. In other examples, the opening of the second mounting groove 1112 can also be positioned in a direction perpendicular to the thickness direction Z of the electronic device. This embodiment of the application does not impose any restrictions on this.

[0168] It should be noted that, as Figure 2c , Figure 3a and Figure 5c As shown, the method of electrical connection between switch 7 and other electronic components (e.g., the first circuit board 31) of electronic device 100 is not limited. In one example, switch 7 can be electrically connected to the first circuit board 31 (e.g., the motherboard) via FPC board 76, or it can be understood that switch 7 can be mounted on FPC board 76, for example, via base 73. Furthermore, a reinforcing piece 77 can be fixed to the side of FPC board 76 away from switch 7 to improve its structural strength and facilitate its installation in housing 1.

[0169] Furthermore, the structural form of the trigger area 71 of switch 7 is not limited. For example... Figure 3a As shown, in one possible implementation, the switch 7 has a protrusion 71A on the side facing the rigid member 62, and the protrusion 71A is the trigger area 71 of the switch 7. The protrusion 71A is used to abut against the rigid member 62 after the elastic bracket 6 is pressed. Since the switch 7 also has a protrusion 71A, similar to the principle of setting a protrusion on the elastic bracket body 61, it can also achieve precise force transmission, mechanical positioning and guidance.

[0170] It should be noted that, as Figure 3a As shown, the specific type of switch 7 is not limited. For example, it can be a mechanical switch or a membrane switch containing a metal spring. Any switch that can generate a rebound force after the keycap 5 is released is acceptable. This application embodiment does not limit this.

[0171] Furthermore, the specific structure of the switch is not limited. For example... Figure 5cAs shown, in one possible implementation, the switch 7 may include a spring 74 and a contact 75. The central portion of the spring 74 protrudes towards the rigid component 62. The materials of the spring 74 and the contact 75 are not limited; for example, the spring 74 may be a metal spring, and the contact 75 may be a metal contact. It should be noted that the number of springs 74 is not limited; there may be one or more. If there are multiple springs 74, they are stacked in the first direction P. This embodiment does not limit this. The specific structural form of the spring is also not limited; for example, it may be a dome switch.

[0172] When no external force is applied, the spring 74 is separated from the contact 75 in the switch 7 circuit, and the circuit is open. When an external force is applied to the central protrusion of the spring 74, the spring 74 undergoes elastic deformation, and the central part concaves (i.e., the central part is recessed away from the rigid component 62). When the spring 74 deforms, its central part contacts the contact 75, thus forming a circuit and allowing current to flow. When the external force disappears, the spring 74 quickly returns to its original shape due to its elasticity, separating from the contact 75, and the circuit is broken again. This rapid rebound ensures accurate triggering and disconnection of the signal, providing the user with clear tactile feedback.

[0173] Furthermore, the switch 7 may also include a housing, with the spring 74 and contact 75 located within the cavity formed by the housing, thus enabling the switch to function as a waterproof and dustproof device. In this case, the area of ​​the housing facing the rigid member 62 constitutes the trigger area 71 of the switch 7. When the trigger area 71 is pressed by the rigid member 62, the trigger area 71 moves toward the spring 74 and presses the spring 74, causing the spring 74 to undergo elastic deformation.

[0174] It should be noted that the specific structure of the outer casing is not limited. For example... Figure 5c As shown, in one possible implementation, the housing may include a base 73 and a top cover 72 mounted on one side of the base 73, with a portion of the top cover 72 forming the trigger area 71 of the switch 7. The top cover 72 and the base 73 (e.g., an insulating base) form a cavity around each other. The specific material of the base 73 is not limited; for example, the base 73 may be an insulating base. When the top cover 72 is subjected to pressing pressure transmitted from the rigid member 62, it can undergo elastic deformation, allowing the trigger area 71 to move towards the spring 74 to press the spring 74. When the pressing pressure is removed, the spring force of the spring 74 and the spring force of the top cover 72 itself can cause the top cover 72 to return to its initial position.

[0175] Furthermore, the specific structural form of the upper cover 72 is not limited. In one possible implementation, such as... Figure 5c As shown, the central portion of the upper cover 72 protrudes in the direction away from the base 73 to form a protrusion 71A, which constitutes the trigger area 71 of the switch 7.

[0176] Furthermore, the material of the top cover 72 is not limited. In one possible implementation, the top cover 72 is made of a rigid material, which can be a metal or a non-metallic material, such as hard plastic (e.g., plastic). In other possible implementations, the top cover 72 can also be made of a soft material, such as soft plastic.

[0177] Furthermore, the thickness of the upper cover 72 is not limited and can be reasonably set according to actual needs. In one possible implementation, the thickness of the upper cover 72 can be 0.01mm-0.1mm, for example, 0.01mm, 0.02mm, 0.05mm, 0.1mm, etc. In other possible implementations, the thickness of the upper cover 72 can also be less than 0.01mm or greater than 0.1mm, and this application embodiment does not impose any restrictions on this.

[0178] like Figure 5c As shown, when the trigger area 71 of switch 7 is not pressed by the rigid component 62, the internal contact 75 of switch 7 is in the open state, the circuit is not connected, and there is no signal output. The spring 74 is in the naturally extended state, providing support for the initial position of the keycap 5.

[0179] When the user presses keycap 5, the rigid component 62 presses the trigger area 71 of the top cover 72 towards the base 73, thereby pressing the spring 74. The spring 74 undergoes elastic deformation, with its center portion concave. When keycap 5 is pressed to a certain extent (usually after reaching a certain travel distance), the contacts 75 inside switch 7 come into contact with each other, forming a closed circuit. At this time, current can flow through the contacts 75, triggering a signal indicating that key 4 has been pressed.

[0180] When the user releases keycap 5, the elastic force of the spring 74, the elastic force of the top cover 72, and the elastic force of the elastic support body 61 cause keycap 5 to return to its initial position. Contact 75 then separates, the circuit is broken, and the signal disappears. Keycap 5 returns to its unpressed state, awaiting the next operation.

[0181] It should be noted that in other possible implementations, the switch 7 may not have a housing. In this case, part of the spring 74 constitutes the trigger area 71 of the switch. In one example, the central part of the spring 74 protrudes to form a protrusion 71A, which constitutes the trigger area 71 of the switch 7.

[0182] It will be understood by those skilled in the art that, as Figures 5a to 7bAs shown, the installation method of the switch 7 and the elastic bracket 6 in the housing 1 is not limited. For example, the switch 7 and the elastic bracket 6 can be assembled together to form an integral structure, and then the integral structure can be installed in the housing 1. Alternatively, the switch 7 and the elastic bracket 6 can be installed separately in the housing 1. This application embodiment does not limit this.

[0183] In one possible implementation, such as Figures 5a to 6b As shown, button 4 may also include a fixed bracket 8, on which switch 7 and elastic bracket 6 are both fixed. The fixed bracket 8 is fixed inside the housing 1 of electronic device 100 to fix elastic bracket 6 and switch 7 inside housing 1. In one example, the fixing part 612 of elastic bracket body 61 is fixedly connected to fixed bracket 8.

[0184] It should be noted that the material of the fixing bracket 8 is not limited. In one possible implementation, the fixing bracket 8 is made of a rigid material to ensure its structural strength and more secure installation in the housing 1 (e.g., within the second mounting groove 1112 of the housing 1). In one example, the rigid material is a non-metallic material, such as rigid plastic, including PS (polystyrene, commonly known as rigid plastic, a transparent, glass-like material), ABS (acrylonitrile-butadiene-styrene copolymer, commonly known as ABS rigid plastic), rigid PVC (polyvinyl chloride), etc. In other examples, the rigid material can also be a metallic material.

[0185] It is understood by those skilled in the art that, as Figures 6a to 6b As shown, the fixing method between the elastic bracket 6 and the fixed bracket 8 is not limited; for example, it can be achieved through snap-fitting, injection molding, or other integrated methods. Figures 6a to 6b As shown, in one possible implementation, the elastic support body 61 of the elastic support 6 is integrally formed onto the fixed support 8 by injection molding, so that the elastic support 6 and the fixed support 8 are fixedly connected.

[0186] It should be noted that the fixing structure between the switch 7 and the flexible bracket 6 and the fixed bracket 8 is not limited. For example... Figures 6a to 6b As shown, and in combination Figure 5c and Figure 7bIt is understood that, along the first direction P, the fixed bracket 8 has a mounting opening 83 that penetrates the fixed bracket 8. The switch 7 is fixed on the side of the fixed bracket 8 away from the keycap 5, and the main body of the switch 7 is located inside the mounting opening 83. A snap-fit ​​groove 84 for accommodating the fixing part 612 is provided around the mounting opening 83, and a limiting hole 85 is provided at the bottom of the snap-fit ​​groove 84. The limiting post 6122 is inserted into the limiting hole 85, and the bottom of the snap-fit ​​groove 84 is connected to the bottom of the limiting groove 6121, thereby allowing the fixing part 612 of the elastic bracket 6 to be embedded in the fixed bracket 8. The upper surface of the fixed bracket 8 is substantially flush with the upper surface of the elastic bracket 6.

[0187] The way the switch 7 is fixed to the fixed bracket 8 is not limited. For example, the switch 7 can be directly fixed to the fixed bracket 8, or it can be indirectly fixed to the fixed bracket 8 through other structural components (e.g., FPC board 76 and reinforcing plate 77).

[0188] In one possible implementation, such as Figures 6a to 6b As shown, and combined with as Figure 7a It is understood that the switch 7 is fixed to the mounting bracket 8 via the FPC board 76 and the reinforcing piece 77. In one example, the switch 7 is fixed to the FPC board 76, and the mutually fixed FPC board 76 and the reinforcing piece 77 are snapped onto one side of the mounting bracket 8. The FPC board 76 can be fixed to one side of the mounting bracket 8 via an adhesive portion 78. The adhesive portion 78 can be, for example, foam adhesive, adhesive backing, etc., and this embodiment of the application does not limit this.

[0189] Furthermore, the method of fixing the bracket 8 to the housing 1 is not limited. For example... Figure 5a and Figure 5b As shown, the mounting bracket 8 is provided with multiple buckles 81, and the housing 1 has corresponding slots 82. The buckles 81 are engaged in the slots 82 to secure the mounting bracket 8 within the housing 1. For example, the mounting bracket 8 is engaged within the second mounting slot 1112 of the housing 1. This restricts the movement of the mounting bracket 8 relative to the housing 1 in various directions. For example, it restricts the movement of the mounting bracket 8 relative to the housing 1 along the extension direction of the frame 111 and in the thickness direction Z of the electronic device. Figure 7b As shown, the movement of the fixed bracket 8 relative to the housing 1 along the wall thickness direction of the frame 111 can be restricted by the elastic contact between the protrusion 6123 on the elastic bracket body 61 and one wall of the second mounting groove 1112, and the contact between the reinforcing piece 77 and the other wall of the second mounting groove 1112.

[0190] Furthermore, the specific structure of keycap 5 is not limited. In one possible implementation, such as Figures 5c to 6bAs shown, the keycap 5 includes a guide rod 52 and a cap body 51. Along a first direction P, the guide rod 52 is disposed between the cap body 51 and the elastic support 6. The axial direction of the guide rod 52 is along the first direction P. One end of the guide rod 52 in the axial direction is connected to or abuts against the cap body 51, and the other end abuts against the second side portion 6102 of the trigger portion 610 of the elastic support 6. The second side portion 6102 is disposed opposite to the first side portion 6101 in the first direction P.

[0191] The housing 1 has a guide hole 1113, and the axial direction of the guide hole 1113 is also set along the first direction P. The guide rod 52 is located inside the guide hole 1113. The guide rod 52 can provide guidance for the movement of the keycap 5 and prevent deviation due to pressing force or rebound force.

[0192] In one example, a guide hole 1113 is formed at the bottom of the first mounting groove 1111, and one end of the guide hole 1113 away from the first mounting groove 1111 communicates with the second mounting groove 1112. The cap body 51 of the keycap 5 is slidably connected to the first mounting groove 1111, and a portion of the cap body 51 extends out of the first mounting groove 1111 and is exposed outside the housing 1. The guide rod 52 of the keycap 5 is slidably connected to the guide hole 1113.

[0193] It should be noted that the fitting method between the guide rod 52 and the cap body 51 is not limited, such as... Figures 5c to 6b As shown, in one possible implementation, the cap body 51 and the guide rod 52 can be separate structures, that is, the guide rod 52 and the cap body 51 are independently provided as two components. In other possible implementations, the cap body 51 and the guide rod 52 can be a single piece, for example, the cap body 51 and the guide rod 52 can be integrally formed.

[0194] like Figures 5c to 6b As shown, in one possible implementation, to prevent external liquid from entering the electronic device 100 through the gap between the guide rod 52 and the guide hole 1113, the keycap 5 also includes a sealing ring 9 sleeved on the outside of the guide rod 52, with the outer circumferential surface of the guide rod 52 sealingly connected to the inner circumferential surface of the sealing ring 9. Furthermore, to position the sealing ring 9, an annular positioning groove 521 is provided on the outer ring surface of the guide rod 52, and the sealing ring 9 is located within this positioning groove 521.

[0195] It should be noted that the number of switches 7 included in button 4 is not limited; for example, there can be one or more. Similarly, the number of elastic brackets 6 is not limited; for example, there can be one or more. The number of guide rods 52 and sealing rings 9 is also not limited; for example, there can be one or more.

[0196] like Figures 5a to 6bAs shown, in one possible implementation, button 4 includes two switches 7 and two elastic supports 6, with the two elastic supports 6 corresponding one-to-one with the two switches 7. In the extension direction of the frame 111 (e.g., the extension direction of the right frame 1117, which also corresponds to the length direction Y of the electronic device), the two switches 7 are spaced apart, and the two elastic supports 6 are also spaced apart. By pressing a keycap 5, the trigger portion 610 and rigid member 62 of each elastic support 6 can be moved towards the corresponding switch 7, and the trigger area 71 of the switch 7 is pressed to trigger the switch 7. This structure is suitable for various button types; for example, it can be used for the volume buttons of the electronic device 100, where triggering one switch increases the volume of the electronic device 100, and triggering the other switch decreases the volume of the electronic device 100.

[0197] Furthermore, when the keycap 5 includes a cap body 51 and a guide rod 52, and the key 4 includes two switches 7 and two elastic supports 6, there are two guide rods 52, each corresponding to one of the two elastic supports 6, and each is used to press the trigger part 610 of the corresponding elastic support 6. Correspondingly, there may also be two sealing rings 9, each corresponding to one of the two guide rods 52, to respectively seal the connection between the outer wall surface of the corresponding guide rod 52 and the wall surface of the guide hole 1113.
