Description

Technical Field

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

[0002] A keyboard is a device for inputting commands and data to operate electronic devices. For users who frequently use keyboards, the typing experience is becoming increasingly important. Achieving a good tactile feel is one of the core requirements for a keyboard.

[0003] Key travel is a crucial parameter affecting the typing feel when a user types. Key travel is the distance a key travels when pressed. A noticeable tactile bump and cushioning within a key travel range enhance the user's typing experience. Summary of the Invention

[0004] This application aims to provide key components, keyboards, and electronic devices with good key feel.

[0005] In a first aspect, embodiments of this application provide a button assembly. The button assembly includes a keycap, a base plate, a first magnetic element, a second magnetic element, and an elastic element. The keycap is movably connected to the base plate. The first magnetic element, the second magnetic element, and the elastic element are all located between the keycap and the base plate. The first magnetic element is fixedly connected to the keycap and encloses a first space. One end of the elastic element is connected to the second magnetic element, and the other end is connected to the base plate. The button assembly includes a first state, a second state, and a third state. In the first state, the first magnetic element and the second magnetic element are spaced apart in a first direction, and the second magnetic element is opposite to the first space. The first magnetic element and the second magnetic element repel each other in the first direction. The length of the elastic element in the first direction is H1, and the first direction is the direction from which the keycap points to the base plate. In the second state, at least a portion of the second magnetic element is located within the first space, and the length of the elastic element in the first direction is H2, where H2 ≤ H1. In the third state, at least a portion of the second magnetic element is located within the first space, and the length of the elastic element in the first direction is H3, where H3 < H2.

[0006] In this embodiment, when the button assembly is in the first state, the first magnetic element and the second magnetic element are spaced apart in the first direction. At this time, a magnetic repulsion force parallel to the first direction can be generated between the first and second magnetic elements. Due to the magnetic repulsion force and its own weight, the second magnetic element compresses the elastic element along the first direction, causing the elastic element to be in a compressed state. The elastic element exerts an elastic force on the second magnetic element along the second direction, which is opposite to the first direction. When the button assembly is in the second and third states, the second magnetic element can be entirely located in the first space or partially located within the first space. At this time, the repulsion force between the first and second magnetic elements in the first direction is equal to zero or close to zero. The elastic element exerts an elastic force on the second magnetic element along the second direction, and the elastic force of the elastic element when the button assembly is in the second state is greater than the elastic force of the elastic element when the button assembly is in the first state; the elastic force of the elastic element when the button assembly is in the third state is greater than the elastic force of the elastic element when the button assembly is in the second state.

[0007] In this embodiment, the button assembly can switch between a first state and a second state. When the button assembly is in the first state, the user can press the keycap along a first direction to switch the button assembly from the first state to the second state. During the transition from the first state to the second state, the first magnetic component and the second magnetic component have a magnetic repulsion force parallel to the first direction, and the magnetic repulsion force between the first magnetic component and the second magnetic component first increases and then decreases, thereby providing the user with a pressing feel and tactile feedback when pressing the button assembly.

[0008] In this embodiment, the button assembly can switch between a second state and a third state. When the button assembly is in the second state, the user can continue to press the keycap along the first direction to switch the button assembly from the second state to the third state. During the transition from the second state to the third state, the second magnetic component compresses the elastic component along the first direction, and the user needs to overcome the elastic force of the elastic component, thereby providing a cushioning sensation during the pressing of the button assembly.

[0009] It is understood that in the embodiments of this application, the pressing sensation and tactile feedback are achieved through the cooperation of the first magnetic component and the second magnetic component, and the cushioning sensation is achieved through the cooperation of the second magnetic component and the elastic component, thereby improving the user's tactile experience when pressing the button component.

[0010] In some embodiments, during the transition of the button assembly from the first state to the second state, the first magnetic element moves along the first direction, and the first magnetic element and the second magnetic element repel each other in the first direction; during the transition of the button assembly from the second state to the third state, both the first magnetic element and the second magnetic element move along the first direction, and the second magnetic element compresses the elastic element.

[0011] In this embodiment, during the transition of the button assembly from the first state to the second state, the first magnetic component and the second magnetic component have a magnetic repulsion force parallel to the first direction. This magnetic repulsion force first increases and then decreases, thereby providing the user with a pressing and tactile feedback when pressing the button assembly. During the transition of the button assembly from the second state to the third state, the second magnetic component compresses the elastic component along the first direction. The user needs to overcome the elastic force of the elastic component, thus providing a cushioning sensation when pressing the button assembly.

[0012] In some implementations, during the transition of the button assembly from the second state to the third state, the length of the elastic element in the first direction decreases.

[0013] In this embodiment, during the transition of the button assembly from the second state to the third state, the second magnetic component continuously compresses the elastic component along the first direction, causing the elastic force of the elastic component on the second magnetic component in the second direction to continuously increase. During this process, the user needs to continuously overcome the elastic force of the elastic component, and the user's pressing force continuously increases, thereby achieving a better cushioning feel and improving the user's tactile experience when pressing the button assembly.

[0014] In some embodiments, the second magnetic element encloses a second space, and in the third state, at least a portion of the elastic element is located within the second space. This helps to reduce the height of the elastic element and the button assembly in the first direction when the button assembly is in the third state, i.e., to reduce the compression height of the button assembly. It is understood that when the button assembly is in the third state, the height of the button assembly in the first direction is the compression height of the button assembly.

[0015] In this embodiment, by reducing the compression height of the button assembly in the third state, the button travel of the button assembly can be larger, for example, the button assembly can achieve a pressing travel greater than 2mm. Specifically, the pressing travel of the button assembly is the distance traveled by the keycap and the first magnetic component during the process of the user pressing the button assembly from the first state to the third state.

[0016] In some embodiments, along the first direction, the first magnetic element includes a first top surface and a first bottom surface disposed opposite to each other, the first top surface facing the keycap, and the magnetic poles of the first top surface and the first bottom surface being opposite; along the first direction, the second magnetic element includes a second top surface and a second bottom surface disposed opposite to each other, the second top surface facing the keycap, the magnetic poles of the second top surface and the second bottom surface being opposite, and the magnetic poles of the second top surface and the first top surface being the same.

[0017] In this embodiment, it is understood that the first magnetic element and the second magnetic element can be axially magnetized, and the magnetization directions of the first magnetic element and the second magnetic element are the same. Thus, when the button assembly is in the first state, the first magnetic element and the second magnetic element are spaced apart in the first direction, and the second magnetic element and the first magnetic element are spatially opposite each other. The first magnetic element and the second magnetic element repel each other in the first direction, and a magnetic repulsive force parallel to the first direction can be generated between them. Furthermore, during the transition of the button assembly from the first state to the second state, the magnetic repulsive force generated between the first magnetic element and the second magnetic element can first increase and then decrease.

[0018] In some embodiments, the first magnetic element includes a magnetic portion that is ring-shaped. This simplifies the fabrication and assembly processes of the first magnetic element and reduces manufacturing costs.

[0019] In some embodiments, the first magnetic element includes a plurality of magnetic parts, which are spaced apart and enclose a first space; the top surface of the magnetic parts is part of a first top surface, the bottom surface of the magnetic parts is part of a first bottom surface, and the magnetic poles of the top surfaces of the plurality of magnetic parts are the same.

[0020] In this embodiment, the shape of the first magnetic component and the size of the first space can be changed by adjusting the positions of multiple magnetic parts of the first magnetic component. Thus, the shape of the first magnetic component and the size of the first space can be set as needed, and the button assembly has a wide range of applications.

[0021] In some embodiments, in a first state, the first bottom surface and the second top surface are spaced apart in a first direction; in a second state and a third state, the second top surface is located in the first space, or the second top surface is located outside the first space; the second bottom surface is located in the first space, or the second bottom surface is located outside the first space.

[0022] It is understood that in this application, when the button assembly is in the second and third states, there are no strict limitations on the positional relationship between the first magnetic element and the second magnetic element. At least a portion of the second magnetic element is located within the first space of the first magnetic element, and the magnetic repulsion force generated between the first and second magnetic elements along the Z-axis is close to or equal to zero. This helps reduce the manufacturing cost of the button assembly, simplifies the assembly process, and improves production efficiency.

[0023] In some implementations, in the second and third states, the first top surface is flush with the second top surface. This allows the first and second magnetic components to overlap to a greater extent in the first direction, which helps reduce the compression height of the button assembly, thereby increasing the pressing stroke of the button assembly and improving the tactile experience.

[0024] In some implementations, in the second and third states, the first bottom surface is flush with the second bottom surface. This allows the first and second magnetic components to overlap to a greater extent in the first direction, which helps reduce the compression height of the button assembly, thereby increasing the pressing stroke of the button assembly and improving the tactile experience.

[0025] In some embodiments, the first magnetic element includes a first magnetic portion and a second magnetic portion spaced apart, the first magnetic portion and the second magnetic portion of the first magnetic element enclosing a first space. Both the first and second magnetic portions of the first magnetic element include a top surface and a bottom surface facing away from each other. The top surfaces of both the first and second magnetic portions of the first magnetic element face the keycap. The magnetic poles of the top surfaces of the first and second magnetic portions of the first magnetic element are opposite, and the magnetic poles of the bottom surfaces of the first and second magnetic portions of the first magnetic element are opposite. The second magnetic element includes a first magnetic portion and a second magnetic portion spaced apart, the first magnetic portion and the second magnetic portion of the second magnetic element enclosing a second space. The second magnetic element's first magnetic portion... Both the first magnetic part and the second magnetic part include a top surface and a bottom surface facing away from each other. The top surface of the first magnetic part of the second magnetic element and the top surface of the second magnetic part of the second magnetic element both face the keycap. The magnetic poles of the top surface of the first magnetic part of the second magnetic element and the bottom surface of the first magnetic part of the second magnetic element are opposite. The first magnetic part of the second magnetic element is correspondingly arranged with the first magnetic part of the first magnetic element, and the magnetic poles of the top surface of the first magnetic part of the second magnetic element are the same as the magnetic poles of the top surface of the first magnetic part of the first magnetic element. The second magnetic part of the second magnetic element is correspondingly arranged with the second magnetic part of the first magnetic element, and the magnetic poles of the top surface of the second magnetic part of the second magnetic element are the same as the magnetic poles of the top surface of the second magnetic part of the first magnetic element.

[0026] In this embodiment, both the first and second magnetic portions of the first magnetic component and the first and second magnetic portions of the second magnetic component can be axially magnetized, and the magnetization directions of the opposing portions of the first and second magnetic components are the same. Thus, a magnetic repulsion force parallel to the first direction can be generated between the first and second magnetic components, and during the transition of the button assembly from the first state to the second state, the magnetic repulsion force between the first and second magnetic components first increases and then decreases.

[0027] Furthermore, by spacing the first magnetic part and the second magnetic part of the first magnetic component, the first space of the first magnetic component is increased. Thus, during the transition of the button assembly from the first state to the second state, the process of increasing magnetic repulsion between the first and second magnetic components is shorter, while the process of decreasing magnetic repulsion is longer, thereby creating a greater sense of depth and improving the tactile feedback of pressing.

[0028] In some embodiments, the first magnetic element includes a first inner side and a first outer side disposed opposite to each other, the first inner side facing the first space, the first outer side being disposed around the first inner side, and the magnetic poles of the first inner side and the first outer side being opposite to each other; the second magnetic element includes a second inner side and a second outer side disposed opposite to each other, the second outer side being disposed around the second inner side, the magnetic poles of the second inner side and the second outer side being opposite to each other, and the magnetic poles of the second inner side and the first inner side being opposite to each other.

[0029] It is understandable that the first magnetic component and the second magnetic component can be magnetized in a radial ring shape, and the magnetization directions of the first magnetic component and the second magnetic component can be opposite.

[0030] Thus, when the button assembly is in the first state, the first magnetic element and the second magnetic element are spaced apart in the first direction, and the second magnetic element and the first magnetic element are spatially opposite each other. The first magnetic element and the second magnetic element repel each other in the first direction, generating a magnetic repulsive force in the first direction between them. Furthermore, during the transition of the button assembly from the first state to the second state, the magnetic repulsive force generated between the first magnetic element and the second magnetic element can first increase and then decrease.

[0031] In some embodiments, the first magnetic element includes a plurality of magnetic parts, which are spaced apart and enclose a first space; the inner surface of the magnetic parts is part of a first inner surface, the outer surface of the magnetic parts is part of a first outer surface, and the magnetic poles of the inner surfaces of the plurality of magnetic parts are the same.

[0032] In this embodiment, the shape of the first magnetic component and the size of the first space can be changed by adjusting the number and position of the multiple magnetic parts of the first magnetic component. Thus, the shape of the first magnetic component and the size of the first space can be set as needed, and the button assembly has a wide range of applications.

[0033] In some embodiments, in the first state, the first inner surface and the second inner surface are spaced apart in the first direction; in the second and third states, the first inner surface surrounds the second outer surface. Thus, when the button assembly is in the first state, a magnetic repulsion force parallel to the first direction can be generated between the first magnetic element and the second magnetic element. When the button assembly is in the second and third states, the magnetic repulsion force parallel to the first direction generated between the first magnetic element and the second magnetic element is zero or close to zero.

[0034] In some embodiments, the first magnetic element includes a first magnetic portion and a second magnetic portion spaced apart, the first magnetic portion and the second magnetic portion of the first magnetic element enclosing a first space. Both the first magnetic portion and the second magnetic portion of the first magnetic element include inner and outer sides facing away from each other. The inner sides of both the first and second magnetic portions of the first magnetic element face the first space. The magnetic poles of the inner sides of the first magnetic portion and the second magnetic portion of the first magnetic element are opposite, and the magnetic poles of the outer sides of the first magnetic portion and the second magnetic portion of the first magnetic element are opposite. The second magnetic element also includes a first magnetic portion and a second magnetic portion spaced apart, the first magnetic portion and the second magnetic portion of the second magnetic element enclosing a second space. The first magnetic portion of the second magnetic element... Both the first magnetic part and the second magnetic part include inner and outer sides facing away from each other. The inner sides of the first magnetic part and the second magnetic part of the second magnetic element both face the second space. The magnetic poles of the inner sides of the first magnetic part and the second magnetic part of the second magnetic element are opposite. The magnetic poles of the outer sides of the first magnetic part and the second magnetic part of the second magnetic element are opposite. The first magnetic part of the second magnetic element is correspondingly arranged with the first magnetic part of the first magnetic element, and the magnetic poles of the inner sides of the first magnetic part of the second magnetic element are opposite. The second magnetic part of the second magnetic element is correspondingly arranged with the second magnetic part of the first magnetic element, and the magnetic poles of the inner sides of the second magnetic part of the second magnetic element are opposite.

[0035] In this embodiment, both the first and second magnetic portions of the first magnetic component and the second magnetic component can be radially annularly magnetized, and the magnetization directions of the opposing portions of the first and second magnetic components are opposite. This allows a magnetic repulsion force parallel to the first direction to be generated between the first and second magnetic components, and during the transition of the button assembly from the first state to the second state, the magnetic repulsion force between the first and second magnetic components first increases and then decreases.

[0036] Furthermore, by spacing the first magnetic part and the second magnetic part of the first magnetic component, the first space of the first magnetic component is increased. Thus, during the transition of the button assembly from the first state to the second state, the process of increasing magnetic repulsion between the first and second magnetic components is shorter, while the process of decreasing magnetic repulsion is longer, thereby creating a greater sense of depth and improving the tactile feedback of pressing.

[0037] In some embodiments, the first magnetic element and the second magnetic element are coaxially arranged.

[0038] In this embodiment, the first magnetic element and the second magnetic element are coaxially arranged. On one hand, when the button assembly is in the first state, the magnetic repulsion force generated between the first and second magnetic elements is relatively large, which is beneficial to achieving a more ideal force-stroke curve and thus a better pressing feel. On the other hand, in the direction perpendicular to the first direction, the resultant force of the interaction force between the first and second magnetic elements is zero or close to zero, which allows the button assembly to have better motion stability during pressing, that is, the first magnetic element is not easy to tilt relative to the second magnetic element. In this way, the magnetic repulsion force generated between the first and second magnetic elements along the Z-axis is also relatively stable, which is beneficial to achieving a more ideal force-stroke curve.

[0039] In some embodiments, the second magnetic element is coaxially arranged with the elastic element.

[0040] In this embodiment, the second magnetic element and the elastic element are coaxially arranged. On one hand, when the second magnetic element compresses the elastic element along the first direction, the elastic element can generate a large elastic force, which is beneficial to achieving a more ideal force-stroke curve and thus a better pressing feel. On the other hand, the elastic element is less likely to generate a component force in the direction perpendicular to the first direction, so that the button assembly can have better motion stability during pressing.

[0041] In some embodiments, the elastic element includes a spring, a silicone pillar, or a foam pillar. For example, the elastic element can be a spring. Springs have better resilience and support, and also have a longer lifespan, better wear resistance, good stability, and low manufacturing cost.

[0042] In some embodiments, the button assembly further includes a first support member and a second support member. One end of the first support member is rotatably connected to the keycap, and the other end is movably connected to the base plate. One end of the second support member is movably connected to the keycap, and the other end is rotatably connected to the base plate. The first support member encloses a first receiving space, and the second support member encloses a second receiving space. At least a portion of the first support member is located within the second receiving space and is rotatably connected to the second support member. During the transition of the button assembly from the first state to the second state and from the second state to the third state, the first receiving space is used to avoid the first magnetic element, the second magnetic element, and the elastic element.

[0043] In this embodiment, the first support and the second support can be used to support the keycaps. During the transition of the key assembly from the first state to the second state and from the second state to the third state, the first accommodating space of the first support can be used to avoid the first magnetic component, the second magnetic component, and the elastic component, thereby preventing the first magnetic component, the second magnetic component, and the elastic component from interfering with each other with the first support, and thus preventing the first magnetic component, the second magnetic component, and the elastic component from misalignment, wear, or even breakage, which is beneficial to the reliability of the key assembly.

[0044] In some embodiments, the button assembly further includes a first support member and a second support member; the first support member includes a first rotating end and a first movable end, the first movable end being movably connected to the keycap, and the first rotating end being rotatably connected to the base plate; the second support member includes a second rotating end and a second movable end, the second movable end being movably connected to the keycap, and the second rotating end being rotatably connected to the base plate; the first support member is provided with a first clearance hole that penetrates the first rotating end, and the second support member is provided with a second clearance hole that penetrates the second rotating end, the first clearance hole and the second clearance hole forming a clearance space; during the transition of the button assembly from the first state to the second state and from the second state to the third state, the clearance space is used to avoid the first magnetic element, the second magnetic element, and the elastic element.

[0045] In this embodiment, the first support and the second support can be used to support the keycaps. During the transition of the key assembly from the first state to the second state and from the second state to the third state, the clearance space can be used to avoid the first magnetic component, the second magnetic component, and the elastic component. This can prevent the first magnetic component, the second magnetic component, and the elastic component from interfering with the first support and the second support, thereby preventing misalignment, wear, or even breakage of the first magnetic component, the second magnetic component, and the elastic component, which is beneficial to the reliability of the key assembly.

[0108] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0109] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0110] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the electronic device 1000 provided in this application in some embodiments.

[0111] This application provides an electronic device 1000. The electronic device 1000 can be a device with a keyboard, such as a laptop computer or personal computer. Exemplarily, the electronic device 1000 includes a keyboard 100 and a display device 200. The keyboard 100 can serve as an input device for the display device 200. The display device 200 can be a display screen, a tablet computer, a laptop computer, a personal digital assistant (PDA), or a mobile phone, or other devices with display functions.

[0112] It is understood that the keyboard 100 can be communicatively connected to the display device 200. In this way, the user can input commands to the display device 200 via the keyboard 100, causing the display device 200 to display according to the input commands. The communication connection includes wired and wireless communication connections. A "wired communication connection" can be understood as multiple components physically contacting and electrically connected; it can also be understood as multiple components in a circuit structure being connected through physical lines that can transmit signals, such as copper foil on a printed circuit board (PCB) or wires. A "wireless communication connection" can be understood as multiple components transmitting signals in a non-contact manner. For example, multiple components can use short-range communication technologies (e.g., Bluetooth, Wireless Fidelity, or Near Field Communication (NFC)).

[0113] For ease of description, and for example, the thickness direction of keyboard 100 is defined as the Z-axis, and the width direction as the Y-axis. The direction perpendicular to both the Y-axis and Z-axis is defined as the X-axis, meaning the length direction of keyboard 100 is the X-axis. It is understood that the coordinate system of keyboard 100 can be flexibly set according to specific needs.

[0114] Please refer to the following: Figure 1 and Figure 2 , Figure 2 yes Figure 1 The keyboard 100 shown is a partial exploded view of its structure in some embodiments.

[0115] In some embodiments, the keyboard 100 includes a housing 1, a circuit board 2, and a plurality of keys 3. It is understood that... Figure 1 and Figure 2 This application only illustrates a certain number of buttons 3, but does not specifically limit the exact number, size, etc. of the buttons 3.

[0116] For example, the housing 1 may include a top plate 11 and a bottom plate 12 disposed opposite to each other, a distal side plate 13 (also called a first side plate 13) and a proximal side plate 14 (also called a second side plate 14) disposed opposite to each other, and a left side plate 15 (also called a third side plate 15) and a right side plate 16 (also called a fourth side plate 16) disposed opposite to each other. The distal side plate 13 and the proximal side plate 14 are connected between the top plate 11 and the bottom plate 12. The left side plate 15 and the right side plate 16 are connected between the top plate 11 and the bottom plate 12, and also connected between the distal side plate 13 and the proximal side plate 14. It is understood that the distal side plate 13 of the housing 1 may be the side plate of the housing 1 furthest from the user during the use of the keyboard 100. The proximal side plate 14 of the housing 1 may be the side plate of the housing 1 closest to the user during the use of the keyboard 100. The left side plate 15 of the housing 1 may be the side plate of the housing 1 closest to the user's left hand during the use of the keyboard 100. The right side panel 16 of the housing 1 can be the side panel of the housing 1 closest to the user's right hand when the user is using the keyboard 100.

[0117] Among them, the top plate 11, bottom plate 12, distal side plate 13, proximal side plate 14, left side plate 15 and right side plate 16 of the shell 1 can enclose the accommodating space 17.

[0118] For example, the top plate 11 of the housing 1 is provided with a plurality of through holes 18. The through holes 18 communicate with the receiving space 17. It is understood that this application does not specifically limit the size, shape, or arrangement of the through holes 18. Furthermore, the size and shape of each through hole 18 may be the same or different.

[0119] It is understood that although a specific structure of the housing 1 has been described above, the housing 1 may adopt other structures in other embodiments, and this application does not limit them in any specific way.

[0120] Please see Figure 2 In some embodiments, the circuit board 2 may include a plurality of trigger terminals 21. Figure 2 The trigger terminal 21 is schematically shown using a dashed box. The trigger terminal 21 is used to generate an electrical signal on the circuit board 2 when pressed by the button 3. The information or instruction composed of this electrical signal can be transmitted to the display device 200. It is understood that this application does not specifically limit the size, shape, or arrangement of the trigger terminal 21. It can be flexibly configured according to requirements. Furthermore, the connection method between the button 3 and the trigger terminal 21 will be described in detail below with reference to the relevant accompanying drawings, and will not be repeated here.

[0121] Please refer to the following: Figures 1 to 3 , Figure 3 yes Figure 1 The schematic diagram shown is a partial cross-sectional view of the keyboard 100 cut along point AA in some embodiments.

[0122] In some embodiments, the circuit board 2 may be located within the receiving space 17 of the housing 1 and mounted on the housing 1. Exemplarily, the circuit board 2 may be connected to the top plate 11 of the housing 1 by means of soldering, screw fastening, or bonding. In other embodiments, the circuit board 2 may also be fixed to the bottom plate 12 of the housing 1. Exemplarily, the plurality of trigger terminals 21 of the circuit board 2 may be correspondingly arranged with a plurality of through holes 18 in the housing 1.

[0123] In some embodiments, the plurality of buttons 3 may be mounted on the circuit board 2. It is understood that the plurality of buttons 3 can be mounted on the housing 1 via the circuit board 2. In other embodiments, the plurality of buttons 3 may also be fixed to the housing 1 by means of adhesive bonding or other methods.

[0124] For example, multiple buttons 3 can be configured one-to-one with multiple trigger terminals 21 on the circuit board 2. A portion of the button 3 can be located inside the through hole 18, and a portion can be located outside the housing 1. In other embodiments, the button 3 can also extend from the receiving space 17 through the through hole 18 to the outside of the housing 1. In this case, a portion of the button 3 can be located inside the receiving space 17, a portion inside the through hole 18, and a portion outside the housing 1.

[0125] It is understandable that multiple buttons 3 include a non-pressed state (also known as the initial state) and a triggered state (also known as the terminated state). Among them, Figures 1 to 3 The diagram schematically illustrates the structure of button 3 in its unpressed state. When button 3 is unpressed, it does not trigger the trigger terminal 21 of circuit board 2, and circuit board 2 does not generate an electrical signal. When button 3 is in the triggered state, it triggers the trigger terminal 21 of circuit board 2, and circuit board 2 generates an electrical signal. It is understood that button 3 can directly press the trigger terminal 21 of circuit board 2, or it can be pressed by other components. This application does not specifically limit the application's capabilities.

[0126] It is understandable that button 3 can also include intermediate states. The intermediate state of button 3 can be any state between the unpressed state and the triggered state of button 3.

[0127] It is understandable that multiple buttons 3 can share a single circuit board 2. In this case, each button 3 and a portion of the circuit board 2 corresponding to that button 3 together constitute a button assembly, that is, a button assembly may include the button 3 and a portion of the circuit board 2.

[0128] In some other examples, each button may also have its own individual button circuit board. Each button's circuit board is communicatively connected to circuit board 2. When the button is in the first state, the button does not trigger the button circuit board, and circuit board 2 does not generate an electrical signal. When the button is in the third state, button 3 triggers the button circuit board, and circuit board 2 can generate an electrical signal.

[0129] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of a button assembly 30 provided in an embodiment of this application. Figure 5 yes Figure 4 The button assembly 30 shown is a partial exploded view in some embodiments.

[0130] In some embodiments, the button assembly 30 may be mounted on the housing 1 (see [reference]). Figure 3 The button assembly 30 may include a keycap 31, a base plate 32, a first magnetic element 33, a second magnetic element 34, an elastic element 35, a first support element 36, and a second support element 37. The keycap 31, the first magnetic element 33, the second magnetic element 34, and the elastic element 35 may all be part of the aforementioned button 3. At least a portion of the base plate 32 may be part of the aforementioned circuit board 2. It is understood that in some other embodiments, the base plate 32 may not be part of the circuit board 2; that is, the base plate 32 may be a structural component distinct from the circuit board 2. In this case, the base plate 32 may be communicatively connected to the circuit board 2.

[0131] Understandable, Figure 4 and Figure 5 The key assembly 30 is shown only schematically, and the actual shape, size, position, and construction of these components are not subject to change. Figure 4 and Figure 5 As limited. In some other embodiments, the button assembly 30 may also have more or fewer components.

[0132] In this embodiment, the keycap 31 can be movably connected to the base plate 32 via the first support member 36 and the second support member 37, allowing the keycap 31 and the base plate 32 to move closer or further apart in the Z-axis direction via the first support member 36 and the second support member 37. The arrangement of the keycap 31, the base plate 32, the first support member 36, and the second support member 37 will be described in detail later with reference to the accompanying drawings.

[0133] In this embodiment, the button component 30 may include a first state, a second state, and a third state. The second state is a state between the first and third states of the button component 30. It can be understood that the first state of the button component 30 corresponds to the unpressed state of button 3 mentioned above, the second state of the button component 30 corresponds to one of the intermediate states of button 3 mentioned above, and the third state of the button component 30 corresponds to the triggered state of button 3 mentioned above.

[0134] In some embodiments, the keycap 31 may include a pressing plate 311 and a frame 312. The pressing plate 311 may include a first surface 3111 and a second surface 3112 facing away from each other. The frame 312 is fixed to the second surface 3112 of the pressing plate 311. The pressing plate 311 and the frame 312 form a first receiving groove 310. Figure 3 As shown, when the button assembly 30 is installed in the housing 1, the first surface 3111 of the press plate 311 can be exposed relative to the through hole 18 of the housing 1. When the user presses the button assembly 30, it contacts the first surface 3111 of the keycap 31.

[0135] For example, the keycap 31 may be generally rectangular. In some other embodiments, the keycap 31 may also be circular or other shapes, which are not limited in this application.

[0136] Please refer to the following: Figure 5 and Figure 6 , Figure 6 yes Figure 4 The diagram shows a partial structural view of the button assembly 30 from another angle in some embodiments. For example, Figure 6 The diagram mainly shows the assembly structure of the keycap 31 and the first magnetic component 33.

[0137] In some embodiments, the keycap 31 is provided with a first mounting groove 313. The opening of the first mounting groove 313 is located on the second surface 3112 of the press plate 311. Exemplarily, the first mounting groove 313 is located at the center of the press plate 311. Exemplarily, the first mounting groove 313 may be generally circular. In other examples, the shape of the first mounting groove 313 may also be rectangular, annular, square, or other shapes, which are not limited in this application.

[0138] In some embodiments, the keycap 31 may include an actuator 314. The actuator 314 may be an elastic element 35, such as a rubber cap, a spring, or a spring. In other examples, the actuator 314 may also be a structural element of other forms. The actuator 314 protrudes from the second surface 3112 of the press plate 311 and is located within the first mounting groove 313. Exemplarily, the actuator 314 may be located at the center of the first mounting groove 313.

[0139] In some embodiments, the keycap 31 may further include a first guide rail block 3151 and a second guide rail block 3152. Both the first guide rail block 3151 and the second guide rail block 3152 protrude from the second surface 3112 of the press plate 311 and are both located within the first receiving groove 310. Exemplarily, the first guide rail block 3151 and the second guide rail block 3152 may be arranged at intervals along the X-axis direction. The first guide rail block 3151 and the second guide rail block 3152 are located on the same side of the first mounting groove 313 in the Y-axis direction.

[0140] In some embodiments, the first guide rail block 3151 is provided with a first guide groove 3153, and the second guide rail block 3152 is provided with a second guide groove 3154. The first guide groove 3153 and the second guide groove 3154 are disposed opposite to each other. For example, both the first guide groove 3153 and the second guide groove 3154 can be strip-shaped. The first guide groove 3153 and the second guide groove 3154 can extend along the Y-axis direction. For example, both the first guide groove 3153 and the second guide groove 3154 can extend beyond the edge 312 of the keycap 31.

[0141] In some embodiments, the keycap 31 may further include a first limiting block 3161 and a second limiting block 3162. Both the first limiting block 3161 and the second limiting block 3162 protrude from the second surface 3112 of the pressing plate 311 and are both located within the first receiving groove 310. Exemplarily, the first limiting block 3161 and the second limiting block 3162 may be arranged at intervals along the X-axis direction. In the Y-axis direction, the first limiting block 3161 and the second limiting block 3162 are located on the same side of the first mounting groove 313, and the first limiting block 3161 and the first guide rail block 3151 are respectively located on both sides of the first mounting groove 313, while the second limiting block 3162 and the second guide rail block 3152 are respectively located on both sides of the first mounting groove 313. In this case, the first guide rail block 3151, the second guide rail block 3152, the first limiting block 3161, and the second limiting block 3162 may be arranged around the first mounting groove 313.

[0142] In some embodiments, the first limiting block 3161 is provided with a first limiting groove 3163, and the second limiting block 3162 is provided with a second limiting groove 3164. The first limiting groove 3163 and the second limiting groove 3164 are disposed opposite to each other. For example, both the first limiting groove 3163 and the second limiting groove 3164 can pass through the first limiting block 3161 and the second limiting block 3162 along the X-axis direction.

[0143] In some embodiments, the keycap 31 may further include a first stop 3171 and a second stop 3172. Exemplarily, the first stop 3171 is positioned directly opposite the space between the first guide block 3151 and the second guide block 3152. The number of first stops 3171 can be one or more. When there are multiple first stops 3171, they can be spaced apart along the X-axis. Exemplarily, the second stop 3172 can be located between the first limiting block 3161 and the second limiting block 3162. In the Y-axis direction, the second stop 3172 and the first stop 3171 can be located on opposite sides of the first mounting groove 313. The number of second stops 3172 can be one or more. When there are multiple second stops 3172, they can be spaced apart along the X-axis.

[0144] In some embodiments, the keycap 31 is further provided with a first clearance groove 318. The opening of the first clearance groove 318 is located on the second surface 3112 of the press plate 311. It is understood that the first clearance groove 318 can be used to provide clearance space for other components of the key assembly 30 or other components of the keyboard 100, thereby preventing interference between the other components of the key assembly 30, other components of the keyboard 100, and the keycap 31. This prevents misalignment, wear, or even breakage caused by collisions between the other components of the key assembly 30 or other components of the keyboard 100 and the keycap 31, thereby extending the service life of the key assembly 30. Furthermore, Figure 5 Two first clearance slots 318 are shown only schematically. This application does not make specific limitations on the number, shape, size and position of the first clearance slots 318, for example, they can be designed according to the specific shape and size of the product.

[0145] Please see Figure 6 In some embodiments, the first magnetic element 33 is fixedly connected to the keycap 31. Exemplarily, the first magnetic element 33 can be fixed to the second surface 3112 of the press plate 311 by welding, bonding, or other methods, and at least a portion of the first magnetic element 33 can be located within the first mounting groove 313. Exemplarily, the first magnetic element 33 can be a magnet, for example, a permanent magnet. In other examples, the first magnetic element 33 can also be an electromagnet or other magnetic element.

[0146] In some embodiments, the first magnetic element 33 may enclose the first space 331. For example, a portion of the trigger element 314 may be located in the first space 331.

[0147] Please refer to the following: Figure 5 and Figure 7 , Figure 7 yes Figure 5 The diagram shows the structure of the base plate 32 in some embodiments.

[0148] In some embodiments, the base plate 32 may include an electrical connection plate 321 and a reinforcing plate 322. The electrical connection plate 321 has a trigger terminal 21. The reinforcing plate 322 is fixedly connected to the electrical connection plate 321. For example, the reinforcing plate 322 may be a steel sheet, aluminum sheet, titanium alloy sheet, etc. The reinforcing plate 322 can be used to improve the strength of the base plate 32. For example, the reinforcing plate 322 may include a first surface 3221 and a second surface 3222 facing away from each other. The second surface 3222 of the reinforcing plate 322 faces the electrical connection plate 321 and is fixed to the electrical connection plate 321. In other embodiments, the reinforcing plate 322 may also form an integral structure with the electrical connection plate 321. Specifically, this application does not limit the specific embodiment.

[0149] For example, the reinforcing plate 322 is provided with a first through hole 323. The first through hole 323 can penetrate through the first surface 3221 and the second surface 3222 of the reinforcing plate 322 and is correspondingly disposed with respect to the trigger end 21 on the electrical connection plate 321. It is understood that the trigger end 21 on the electrical connection plate 321 can be exposed relative to the first through hole 323. For example, the reinforcing plate 322 is also provided with a limiting protrusion 324. The limiting protrusion 324 protrudes from the first surface 3221 of the reinforcing plate 322 and is disposed around the first through hole 323.

[0150] For example, the reinforcing plate 322 is further provided with a first clearance hole 3251, a second clearance hole 3252, a third clearance hole 3253, and a fourth clearance hole 3254. The first clearance hole 3251, the second clearance hole 3252, the third clearance hole 3253, and the fourth clearance hole 3254 can all penetrate through the first surface 3221 and the second surface 3222 of the reinforcing plate 322.

[0151] For example, the reinforcing plate 322 further includes a first limiting portion 3261, a second limiting portion 3262, a third limiting portion 3263, and a fourth limiting portion 3264. The first limiting portion 3261, the second limiting portion 3262, the third limiting portion 3263, and the fourth limiting portion 3264 all protrude from the first surface 3221 of the reinforcing plate 322. The first limiting portion 3261 can extend along the negative Y-axis to above the first clearance hole 3251. That is, a portion of the first limiting portion 3261 can be disposed opposite to the first clearance hole 3251. The second limiting portion 3262 can extend along the negative Y-axis to above the second clearance hole 3252. That is, a portion of the second limiting portion 3262 can be disposed opposite to the second clearance hole 3252. The third limiting portion 3263 can extend along the positive Y-axis to above the third clearance hole 3253. That is, a portion of the third limiting part 3263 can be disposed opposite to the third clearance hole 3253. The fourth limiting part 3264 can extend along the positive Y-axis to above the fourth clearance hole 3254. That is, a portion of the fourth limiting part 3264 can be disposed opposite to the fourth clearance hole 3254.

[0152] For example, the first limiting portion 3261 and the second limiting portion 3262 can be arranged at intervals along the X-axis direction. In the Y-axis direction, the first limiting portion 3261 and the second limiting portion 3262 are located on the same side of the first through hole 323. For example, the third limiting portion 3263 and the fourth limiting portion 3264 can be arranged at intervals along the X-axis direction. In the Y-axis direction, the third limiting portion 3263 and the fourth limiting portion 3264 are located on the same side of the first through hole 323, with the first limiting portion 3261 and the third limiting portion 3263 located on opposite sides of the first through hole 323, and the second limiting portion 3262 and the fourth limiting portion 3264 located on opposite sides of the first through hole 323. In this case, the first limiting portion 3261, the second limiting portion 3262, the third limiting portion 3263, and the fourth limiting portion 3264 can be arranged around the first through hole 323.

[0153] In some embodiments, the reinforcing plate 322 is provided with a plurality of clearance spaces 327. The clearance spaces 327 may penetrate through the first surface 3221 and the second surface 3222 of the reinforcing plate 322. Exemplarily, at least one clearance space 327 may communicate with a first clearance hole 3251. At least one clearance space 327 may communicate with a second clearance hole 3252. At least one clearance space 327 may communicate with a third clearance hole 3253. At least one clearance space 327 may communicate with a fourth clearance hole 3254.

[0154] Please refer to the following: Figure 8 and Figure 9 , Figure 8 yes Figure 4 The diagram shown is a partial structural schematic of the button assembly 30 in some embodiments. Figure 9 yes Figure 8 The diagram shows a partial cross-sectional view of the button assembly 30 taken along point BB. Exemplary, Figure 8 and Figure 9 The diagram mainly shows the assembly structure of the base plate 32, the second magnetic component 34, and the elastic component 35.

[0155] In some embodiments, the second magnetic element 34 may include a first portion 341 and a second portion 342. The second portion 342 is located on one side of the first portion 341 and is fixedly connected to the first portion 341. Exemplarily, the first portion 341 and the second portion 342 may be fixedly connected by welding, bonding, or other methods. In other embodiments, the first portion 341 and the second portion 342 may also be integrally formed structural components. This application does not impose any limitations on this. The first portion 341 may enclose a second space 343.

[0156] For example, the second portion 342 may cover the second space 343 of the first portion 341. For example, the second portion 342 is provided with a second through hole 344. The second through hole 344 can communicate with the second space 343. For example, the second portion 342 may be a steel sheet, a magnet, etc. The materials of the second portion 342 and the second portion 342 may be the same or different.

[0157] In some embodiments, one end of the elastic member 35 is connected to the base plate 32, and the other end is connected to the second magnetic member 34. For example, one end of the elastic member 35 extends into the first through hole 323 of the reinforcing plate 322 of the base plate 32, and can be fixedly connected to the electrical connection plate 321 of the base plate 32 by means of welding, bonding, snap-fitting, etc.

[0158] For example, the other end of the elastic member 35 may be located within the first space 331 of the first portion 341 of the second magnetic member 34, and may be fixedly connected to the second portion 342 of the second magnetic member 34 by means of welding, bonding, snap-fitting, etc. It is understood that the second portion 342 of the second magnetic member 34 may be located on the side of the first portion 341 facing away from the elastic member 35.

[0159] For example, the central axis of the elastic member 35 is parallel to the Z-axis direction. It is understood that the elastic member 35 can be in a compressed state. In the Z-axis direction, the second magnetic member 34 can be suspended above the base plate 32 via the elastic member 35. The second magnetic member 34 can move closer to or further away from the base plate 32 in the Z-axis direction. It is understood that as the second magnetic member 34 moves closer to the base plate 32 along the Z-axis direction, the second magnetic member 34 compresses the elastic member 35.

[0160] For example, the elastic element 35 can be a spring. Springs have better resilience and support, and also have a longer lifespan, better wear resistance, good stability, and low manufacturing cost. In some other embodiments, the elastic element 35 can also be a silicone pillar, a foam pillar, or other elastic structural components. The embodiment of the elastic element 35 being a silicone pillar will be described in detail later with reference to the relevant drawings. It is understood that this application does not strictly limit the type, size, and shape of the elastic element 35.

[0161] Please refer to the following: Figure 10 and Figure 11A , Figure 10 yes Figure 4 The schematic diagram shown is a partial cross-sectional structure of the button assembly 30 cut along CC in some embodiments, in the first state. Figure 11A yes Figure 5 The diagram shows the structure of the first magnetic element 33 and the second magnetic element 34 in some embodiments. Exemplary, Figure 11A This mainly shows the relative positions between the first magnetic element 33 and the second magnetic element 34 when the button assembly 30 is in the first state.

[0162] In some embodiments, the keycap 31 and the base plate 32 can be arranged along the Z-axis direction, and the first magnetic element 33, the second magnetic element 34, and the elastic element 35 can be located between the keycap 31 and the base plate 32. For example, when the key assembly 30 is in the first state, the user does not press the keycap 31. The trigger element 314 of the keycap 31 is opposite to and spaced apart from the second through hole 344 of the second magnetic element 34 in the Z-axis direction. For example, the distance between the trigger element 314 of the keycap 31 and the trigger end 21 of the base plate 32 in the Z-axis direction is S1, where S1 > 0. At this time, the trigger element 314 of the keycap 31 does not trigger the trigger end 21 on the base plate 32, and the base plate 32 does not generate an electrical signal.

[0163] In some embodiments, the first magnetic element 33 may include a magnetic portion 330. The magnetic portion 330 may be generally ring-shaped, such as a circular ring or a square ring. This simplifies the fabrication and assembly processes of the first magnetic element 33 and reduces manufacturing costs. For example, along a first direction, the first magnetic element 33 includes a first top surface 332 and a first bottom surface 333 facing away from each other. The first top surface 332 faces the keycap 31. The first magnetic element 33 also includes a first inner side surface 334 and a first outer side surface 335 facing away from each other, both connected between the first top surface 332 and the first bottom surface 333. The first inner side surface 334 may face the first space 331, and the first outer side surface 335 may surround the first inner side surface 334.

[0164] In some embodiments, the second magnetic element 34 may include a magnetic portion 340. The magnetic portion 340 may be generally ring-shaped, such as a circular ring or a square ring. This simplifies the fabrication and assembly processes of the second magnetic element 34 and reduces manufacturing costs.

[0165] For example, along the first direction, the second magnetic element 34 includes a second top surface 345 and a second bottom surface 346 disposed opposite to each other. The second top surface 345 faces the keycap 31. It is understood that the second top surface 345 may be the surface of the second portion 342 of the second magnetic element 34 facing away from the first portion 341. The second magnetic element 34 also includes a second inner side surface 347 and a second outer side surface 348 disposed opposite to each other, both connected between the second top surface 345 and the second bottom surface 346. The second inner side surface 347 may face the second space 343 and the second through hole 344, and the second outer side surface 348 may be disposed around the second inner side surface 347. It is understood that the structure of the second magnetic element 34 is similar to the structure of the first magnetic element 33. For details regarding the structural configuration of the second magnetic element 34, please refer to the relevant description of the structural configuration of the first magnetic element 33 above.

[0166] For example, the magnetic poles of the first top surface 332 and the first bottom surface 333 of the first magnetic element 33 are opposite. The magnetic poles of the second top surface 345 and the second bottom surface 346 of the second magnetic element 34 are opposite. It is understood that the first magnetic element 33 and the second magnetic element 34 can be axially magnetized. For example, the magnetic poles of the first top surface 332 and the second top surface 345 are the same. In this case, the magnetic poles of the first bottom surface 333 and the second bottom surface are also the same. For example, the magnetic poles of both the first top surface 332 and the second top surface 345 can be S poles, and the magnetic poles of both the first bottom surface 333 and the second bottom surface 346 can be N poles; or, the magnetic poles of both the first top surface 332 and the second top surface 345 can be N poles, and the magnetic poles of both the first bottom surface 333 and the second bottom surface 346 can be S poles. This application does not limit this. It is understood that the magnetization directions of the first magnetic element 33 and the second magnetic element 34 are the same.

[0167] like Figure 10 As shown, when the button assembly 30 is in the first state, the first magnetic element 33 and the second magnetic element 34 are spaced apart in the Z-axis direction, and the second magnetic element 34 and the first space 331 of the first magnetic element 33 are opposite to each other. For example, the first top surface 332 of the first magnetic element 33 and the second top surface 345 of the second magnetic element 34 both face the keycap 31, and the first bottom surface 333 of the first magnetic element 33 and the second top surface 345 of the second magnetic element 34 are spaced apart in the Z-axis direction. The first inner surface 334 of the first magnetic element 33 and the second inner surface 347 of the second magnetic element 34 are spaced apart in the Z-axis direction. At this time, the first magnetic element 33 and the second magnetic element 34 are repelled in the Z-axis direction.

[0168] It is understandable that when the key assembly 30 is in the first state, a magnetic repulsion force can be generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis. Due to the magnetic repulsion and its own weight, the second magnetic element 34 compresses the elastic element 35 along the first direction, causing the elastic element 35 to be in a first compressed state. The elastic element 35 exerts an elastic force on the second magnetic element 34 along the second direction. At this time, the length of the elastic element 35 in the first direction is H1. The first direction is the direction from the keycap 31 to the base plate 32. The second direction is the direction from the base plate 32 to the keycap 31. It is understandable that the first and second directions are opposite. The first direction can be the negative Z-axis direction, and the second direction can be the positive Z-axis direction.

[0169] Please see Figure 11B , Figure 11B yes Figure 5 The diagram shows the structure of the first magnetic element 33 and the second magnetic element 34 in some other embodiments. Exemplary, Figure 11B This mainly shows the relative positions between the first magnetic element 33 and the second magnetic element 34 when the button assembly 30 is in the first state.

[0170] In other embodiments, the magnetic poles of the first inner surface 334 of the first magnetic element 33 are opposite to those of the first outer surface 335. The magnetic poles of the second inner surface 347 of the first magnetic element 33 are opposite to those of the second outer surface 348. It is understood that the first magnetic element 33 and the second magnetic element 34 can be radially annularly magnetized. Exemplarily, the magnetic poles of the second inner surface 347 of the second magnetic element 34 are opposite to those of the first inner surface 334 of the first magnetic element 33. In this case, the magnetic poles of the second outer surface 348 of the second magnetic element 34 are also opposite to those of the first outer surface 335 of the first magnetic element 33. For example, the magnetic poles of both the first inner surface 334 and the second inner surface 347 can be S poles, and the magnetic poles of both the first outer surface 335 and the second outer surface 348 can be N poles; or, the magnetic poles of both the first inner surface 334 and the second inner surface 347 can be N poles, and the magnetic poles of both the first outer surface 335 and the second outer surface 348 can be S poles. This application does not limit this. It is understandable that the magnetization directions of the first magnetic element 33 and the second magnetic element 34 can be opposite.

[0171] Understandably, when the button assembly 30 is in the first state, the first bottom surface 333 of the first magnetic element 33 and the second top surface 345 of the second magnetic element 34 are spaced apart in the Z-axis direction. The first inner surface 334 of the first magnetic element 33 and the second inner surface 347 of the second magnetic element 34 are also spaced apart in the Z-axis direction. At this time, the first magnetic element 33 and the second magnetic element 34 repel each other in the Z-axis direction. That is, a magnetic repulsive force can be generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis direction.

[0172] It is understood that the second magnetic element 34 and the first magnetic element 33 in this embodiment may have the same or similar structure, or different structure. In this embodiment, the second magnetic element 34 and the first magnetic element 33 have the same structure but different dimensions. The basic design of the component structure and the magnetic pole design of the second magnetic element 34 can refer to the relevant scheme of the first magnetic element 33. At the same time, slight differences in the detailed structure of the components between the second magnetic element 34 and the first magnetic element 33 are allowed. Specific details will not be elaborated here.

[0173] It is understood that in the above embodiments, both the first magnetic element 33 and the second magnetic element 34 include a magnetic portion, and the magnetic portion 330 of the first magnetic element 33 surrounds the first space 331, while the magnetic portion 340 of the second magnetic element 34 surrounds the second space 343. However, the structures of the first magnetic element 33 and the second magnetic element 34 can also be implemented in various ways. The structures of the first magnetic element 33 and the second magnetic element 34 in other embodiments will be described below with reference to the accompanying drawings.

[0174] Please see Figure 12A , Figure 12A yes Figure 5 The diagram shows the structure of the first magnetic element 33 and the second magnetic element 34 in some other embodiments.

[0175] In some embodiments, both the first magnetic element 33 and the second magnetic element 34 may include a plurality of magnetic portions 330 spaced apart. The plurality of magnetic portions 330 of the first magnetic element 33 may collectively enclose a first space 331. Exemplarily, each of the plurality of magnetic portions 330 of the first magnetic element 33 includes a top surface 3301 and a bottom surface (not shown) disposed opposite to each other. The top surfaces 3301 of the plurality of magnetic portions 330 of the first magnetic element 33 collectively constitute a first top surface 332 of the first magnetic element 33 (see [link to documentation]). Figure 11A That is, the top surface 3301 of each magnetic part 330 of the first magnetic element 33 is part of the first top surface 332 of the first magnetic element 33. The bottom surfaces of the multiple magnetic parts 330 of the first magnetic element 33 together constitute the first bottom surface 333 of the first magnetic element 33 (see [link]). Figure 11A That is, the bottom surface of each magnetic part 330 of the first magnetic element 33 is a part of the first bottom surface 333 of the first magnetic element 33.

[0176] For example, each of the plurality of magnetic portions 330 of the first magnetic element 33 includes an inner side surface 3303 and an outer side surface 3304 disposed opposite to each other. The inner side surfaces 3303 of the plurality of magnetic portions 330 of the first magnetic element 33 collectively constitute the first inner side surface 334 of the first magnetic element 33 (see [link]). Figure 11AThat is, the inner surface 3303 of each magnetic part 330 of the first magnetic element 33 is part of the first inner surface 334 of the first magnetic element 33. The outer surfaces 3304 of the plurality of magnetic parts 330 of the first magnetic element 33 together constitute the first outer surface 335 of the first magnetic element 33 (see [link]). Figure 11A That is, the outer surface 3304 of each magnetic part 330 of the first magnetic element 33 is a part of the first outer surface 335 of the first magnetic element 33.

[0177] In this design, multiple magnetic portions 340 of the second magnetic element 34 collectively enclose a second space 343. Each of the multiple magnetic portions 340 of the second magnetic element 34 includes a top surface 3401 and a bottom surface (not shown) facing away from each other. The top surfaces 3401 of the multiple magnetic portions 340 of the second magnetic element 34 collectively constitute a second top surface 345 of the second magnetic element 34; that is, the top surface 3401 of each magnetic portion 340 of the second magnetic element 34 is a part of the second top surface 345 of the second magnetic element 34. Similarly, the bottom surfaces of the multiple magnetic portions 340 of the second magnetic element 34 collectively constitute a second bottom surface 346 of the second magnetic element 34; that is, the bottom surface of each magnetic portion 340 of the second magnetic element 34 is a part of the second bottom surface 346 of the second magnetic element 34.

[0178] For example, each of the plurality of magnetic portions 340 of the second magnetic element 34 includes an inner side surface 3403 and an outer side surface 3404 disposed opposite to each other. The inner side surfaces 3403 of the plurality of magnetic portions 340 of the second magnetic element 34 collectively constitute a second inner side surface 347 of the second magnetic element 34, that is, the inner side surface 3403 of each magnetic portion 340 of the second magnetic element 34 is a part of the second inner side surface 347 of the second magnetic element 34. Similarly, the outer side surfaces 3404 of the plurality of magnetic portions 340 of the second magnetic element 34 collectively constitute a second outer side surface 348 of the second magnetic element 34, that is, the outer side surface 3404 of each magnetic portion 340 of the second magnetic element 34 is a part of the second outer side surface 348 of the second magnetic element 34.

[0179] like Figure 12A As shown in (a) and (b), the plurality of magnetic portions 330 of the first magnetic element 33 and the plurality of magnetic portions 340 of the second magnetic element 34 can both be arc-shaped, or as shown in (a) and (b). Figure 12A As shown in (c), the plurality of magnetic portions 330 of the first magnetic element 33 and the plurality of magnetic portions 340 of the second magnetic element 34 can all be rectangular. It is understood that this application does not specifically limit the size, shape, or arrangement of the plurality of magnetic portions 330 of the first magnetic element 33 and the plurality of magnetic portions 340 of the second magnetic element 34. Furthermore, the size and shape of each magnetic portion 330 of the first magnetic element 33 and each magnetic portion 340 of the second magnetic element 34 can be the same or different.

[0180] like Figure 12AAs shown in (a) and (c), the first magnetic element 33 may include four magnetic portions 330. The second magnetic element 34 may include four magnetic portions 340. Figure 12A As shown in (b), the first magnetic element 33 may include two magnetic portions 330. The second magnetic element 34 may include two magnetic portions 340. In other embodiments, the first magnetic element 33 and / or the second magnetic element 34 may also include three or more than four magnetic portions. This application does not limit this.

[0181] In this embodiment, by adjusting the number, position, and arrangement of the magnetic parts 330 of the first magnetic element 33, and by adjusting the number, position, and arrangement of the magnetic parts 340 of the second magnetic element 34, the magnetic pole arrangement, shape, and dimensions of the first space 331 and the second space 343 of the first magnetic element 33 and the second magnetic element 34 can be changed. Thus, the magnetic pole arrangement, shape, and dimensions of the first space 331 and the second space 343 of the first magnetic element 33 and the second magnetic element 34 can all be set as needed, and the button assembly 30 has a wide range of applications.

[0182] Please see Figure 12B , Figure 12B yes Figure 5 The diagram shows a cross-sectional view of the first magnetic element 33 and the second magnetic element 34 in some other embodiments. Exemplary, Figure 12B This mainly shows the relative positions between the first magnetic element 33 and the second magnetic element 34 when the button assembly 30 is in the first state.

[0183] In some embodiments, the plurality of magnetic portions 330 of the first magnetic element 33 may include first magnetic portions 330a and second magnetic portions 330b spaced apart. Similarly, the plurality of magnetic portions 340 of the second magnetic element 34 may also include first magnetic portions 340a and second magnetic portions 340b spaced apart. The first magnetic portions 330a of the first magnetic element 33 correspond to the first magnetic portions 340a of the second magnetic element 34, and the second magnetic portions 330b of the first magnetic element 33 correspond to the second magnetic portions 340b of the second magnetic element 34. It is understood that the arrangement and direction of the first magnetic portions 330a and second magnetic portions 330b of the first magnetic element 33 are the same as those of the first magnetic portions 340a and second magnetic portions 340b of the second magnetic element 34.

[0184] like Figure 12BAs shown in (a) and (b) in some embodiments, the top surface 3301 of the first magnetic portion 330a of the first magnetic element 33 has opposite magnetic poles to the bottom surface 3302 of the first magnetic portion 330a. For example, the top surface 3301 of the first magnetic portion 330a is the S pole, and the bottom surface 3302 of the first magnetic portion 330a is the N pole; or, the top surface 3301 of the first magnetic portion 330a is the N pole, and the bottom surface 3302 of the first magnetic portion 330a is the S pole. It is understood that the first magnetic portion 330a may be axially magnetized.

[0185] For example, the top surface 3301 of the second magnetic portion 330b of the first magnetic element 33 has opposite magnetic poles to the bottom surface 3302 of the second magnetic portion 330b of the first magnetic element 33. The top surface 3401 of the first magnetic portion 340a of the second magnetic element 34 has opposite magnetic poles to the bottom surface 3402 of the first magnetic portion 340a of the second magnetic element 34. The top surface 3401 of the second magnetic portion 340b of the second magnetic element 34 has opposite magnetic poles to the bottom surface 3402 of the second magnetic portion 340b of the second magnetic element 34. It is understood that the second magnetic portion 330b of the first magnetic element 33 and the first magnetic portion 340a and the second magnetic portion 340b of the second magnetic element 34 can both be axially magnetized. The arrangement of the magnetic poles of the second magnetic portion 330b of the first magnetic element 33 and the first magnetic portion 340a and the second magnetic portion 340b of the second magnetic element 34 can be found in the section on the arrangement of the magnetic poles of the first magnetic portion 330a of the first magnetic element 33. It will not be repeated here.

[0186] like Figure 12B As shown in (a), in some examples, the top surface 3301 of the first magnetic portion 330a of the first magnetic element 33 has the same magnetic pole as the top surface 3301 of the second magnetic portion 330b of the first magnetic element 33. In this case, the bottom surface 3302 of the first magnetic portion 330a of the first magnetic element 33 has the same magnetic pole as the bottom surface 3302 of the second magnetic portion 330b of the first magnetic element 33.

[0187] For example, the top surface 3401 of the first magnetic portion 340a of the second magnetic member 34 and the top surface 3401 of the second magnetic portion 340b of the second magnetic member 34 have the same magnetic poles, and both have the same magnetic poles as the top surface 3301 of the first magnetic portion 330a of the first magnetic member 33. At this time, the bottom surface 3402 of the first magnetic portion 340a of the second magnetic member 34 and the bottom surface 3402 of the second magnetic portion 340b of the second magnetic member 34 have the same magnetic poles, and both have the same magnetic poles as the bottom surface 3302 of the first magnetic portion 330a of the first magnetic member 33.

[0188] like Figure 12BAs shown in (b), in some other examples, the top surface 3301 of the first magnetic portion 330a of the first magnetic element 33 has opposite magnetic poles to the top surface 3301 of the second magnetic portion 330b of the first magnetic element 33. In this case, the bottom surface 3302 of the first magnetic portion 330a of the first magnetic element 33 has opposite magnetic poles to the bottom surface 3302 of the second magnetic portion 330b of the first magnetic element 33.

[0189] For example, the top surface 3401 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the top surface 3301 of the second magnetic portion 340b of the second magnetic member 34. At this time, the bottom surface 3402 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the bottom surface 3402 of the second magnetic portion 340b of the second magnetic member 34.

[0190] For example, the top surface 3401 of the first magnetic portion 340a of the second magnetic member 34 has the same magnetic pole as the top surface 3301 of the first magnetic portion 330a of the first magnetic member 33. At this time, the bottom surface 3402 of the first magnetic portion 340a of the second magnetic member 34 has the same magnetic pole as the bottom surface 3302 of the first magnetic portion 330a of the first magnetic member 33.

[0191] For example, the top surface 3401 of the second magnetic portion 340b of the second magnetic member 34 has the same magnetic pole as the top surface 3301 of the second magnetic portion 330b of the first magnetic member 33. At this time, the bottom surface 3402 of the second magnetic portion 340b of the second magnetic member 34 has the same magnetic pole as the bottom surface 3302 of the second magnetic portion 330b of the first magnetic member 33.

[0192] like Figure 12B As shown in (c) and (d) in some embodiments, the inner surface 3303 of the first magnetic portion 330a of the first magnetic element 33 has the same magnetic pole as the outer surface 3304 of the first magnetic portion 330a. For example, the inner surface 3303 of the first magnetic portion 330a is the S pole, and the outer surface 3304 of the first magnetic portion 330a is the N pole; or, the inner surface 3303 of the first magnetic portion 330a is the N pole, and the outer surface 3304 of the first magnetic portion 330a is the S pole. It is understood that the first magnetic portion 330a can be radially annularly magnetized.

[0193] For example, the inner surface 3303 of the second magnetic portion 330b of the first magnetic element 33 has opposite magnetic poles to the outer surface 3304 of the second magnetic portion 330b of the first magnetic element 33. Similarly, the inner surface 3403 of the first magnetic portion 340a of the second magnetic element 34 has opposite magnetic poles to the outer surface 3404 of the first magnetic portion 340a of the second magnetic element 34. The inner surface 3403 of the second magnetic portion 340b of the second magnetic element 34 has opposite magnetic poles to the outer surface 3404 of the second magnetic portion 340b of the second magnetic element 34. It is understood that the second magnetic portion 330b of the first magnetic element 33 and the first magnetic portion 340a and second magnetic portion 340b of the second magnetic element 34 can both be radially annularly magnetized. The arrangement of the magnetic poles of the second magnetic portion 330b of the first magnetic element 33 and the first magnetic portion 340a and second magnetic portion 340b of the second magnetic element 34 can be found in the section on the arrangement of the magnetic poles of the first magnetic portion 330a of the first magnetic element 33. This will not be elaborated further here.

[0194] like Figure 12B As shown in (c), in some examples, the inner surface 3303 of the first magnetic portion 330a of the first magnetic element 33 has the same magnetic pole as the inner surface 3303 of the second magnetic portion 330b of the first magnetic element 33. In this case, the outer surface 3304 of the first magnetic portion 330a of the first magnetic element 33 has the same magnetic pole as the outer surface 3304 of the second magnetic portion 330b of the first magnetic element 33.

[0195] For example, the inner surface 3403 of the first magnetic portion 340a of the second magnetic member 34 has the same magnetic pole as the inner surface 3403 of the second magnetic portion 340b of the second magnetic member 34, and both are opposite to the magnetic pole of the inner surface 3303 of the first magnetic portion 330a of the first magnetic member 33. At this time, the outer surface 3404 of the first magnetic portion 340a of the second magnetic member 34 has the same magnetic pole as the outer surface 3404 of the second magnetic portion 340b of the second magnetic member 34, and both are opposite to the magnetic pole of the outer surface 3404 of the first magnetic portion 330a of the first magnetic member 33.

[0196] like Figure 12B As shown in (d), in some other examples, the inner surface 3303 of the first magnetic portion 330a of the first magnetic element 33 has the opposite magnetic pole to the inner surface 3303 of the second magnetic portion 330b of the first magnetic element 33. In this case, the outer surface 3304 of the first magnetic portion 330a of the first magnetic element 33 has the opposite magnetic pole to the outer surface 3304 of the second magnetic portion 330b of the first magnetic element 33.

[0197] For example, the inner surface 3403 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the inner surface 3403 of the second magnetic portion 340b of the second magnetic member 34. At this time, the outer surface 3404 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the outer surface 3404 of the second magnetic portion 340b of the second magnetic member 34.

[0198] For example, the inner surface 3403 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the inner surface 3303 of the first magnetic portion 330a of the first magnetic member 33. At this time, the outer surface 3404 of the first magnetic portion 340a of the second magnetic member 34 has the opposite magnetic pole to the outer surface 3304 of the first magnetic portion 330a of the first magnetic member 33.

[0199] For example, the inner surface 3403 of the second magnetic portion 340b of the second magnetic member 34 has the opposite magnetic pole to the inner surface 3303 of the second magnetic portion 330b of the first magnetic member 33. At this time, the outer surface 3404 of the second magnetic portion 340b of the second magnetic member 34 has the opposite magnetic pole to the outer surface 3304 of the second magnetic portion 330b of the first magnetic member 33.

[0200] In some other embodiments, the plurality of magnetic portions 330 of the first magnetic element 33 may further include a third magnetic portion, and the third magnetic portion of the first magnetic element 33 is spaced apart from the first magnetic portion 330a and the second magnetic portion 330b of the first magnetic element 33. Similarly, the plurality of magnetic portions 340 of the second magnetic element 34 may also include a third magnetic portion, and the third magnetic portion of the second magnetic element 34 is spaced apart from the first magnetic portion 340a and the second magnetic portion 340b of the second magnetic element 34. The third magnetic portions of the first magnetic element 33 and the third magnetic portions of the second magnetic element 34 are correspondingly arranged.

[0201] In some examples, the third magnetic portion of the first magnetic element 33 and the third magnetic portion of the second magnetic element 34 can both be axially magnetized. The top surface of the third magnetic portion of the first magnetic element 33 may have the same or opposite magnetic poles as the top surface 3301 of the first magnetic portion 330a of the first magnetic element 33. The top surface of the third magnetic portion of the second magnetic element 34 has the same magnetic poles as the top surface of the third magnetic portion of the first magnetic element 33.

[0202] In other examples, the third magnetic portion 330 may be radially annularly magnetized. The magnetic poles of the inner surface of the third magnetic portion of the first magnetic member 33 may be the same as or opposite to the magnetic poles of the inner surface 3303 of the first magnetic portion 330a of the first magnetic member 33. The magnetic poles of the inner surface of the third magnetic portion of the second magnetic member 34 are opposite to those of the inner surface of the third magnetic portion of the first magnetic member 33.

[0203] Please see Figure 13 , Figure 13 yes Figure 4The schematic diagram shown is a partial cross-sectional structure of the button assembly 30 cut along CC in some embodiments, in the second state.

[0204] In some embodiments, when the button assembly 30 is in the second state, the user presses the keycap 31 along the first direction. At least a portion of the second magnetic element 34 is located within the first space 331. It is understood that the second magnetic element 34 may be entirely or partially located within the first space 331. In this case, the first inner surface 334 of the first magnetic element 33 may surround at least a portion of the second outer surface 348 of the second magnetic element 34. The repulsive force between the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction is equal to or close to zero.

[0205] For example, the keycap 31 can abut against the second magnetic element 34, such that the second surface of the keycap 31's pressing plate 311 can contact the first top surface 332 of the second magnetic element 34. The user presses the keycap 31 along a first direction, causing the keycap 31 to exert a force on the second magnetic element 34 along the first direction. This allows the second magnetic element 34 to compress the elastic element 35 in the first direction, placing the elastic element 35 in a second compressed state. The elastic element 35 exerts an elastic force on the second magnetic element 34 along a second direction. At this time, the length of the elastic element 35 in the Z-axis direction is H2, and H2 ≤ H1. For example, H2 < H1, meaning the length of the elastic element 35 in the second compressed state is less than its length in the first compressed state.

[0206] For example, the trigger 314 of the keycap 31 can pass through the second through hole 344 of the second magnetic member 34, extend into the second space 343 of the second magnetic member 34, and also extend into the interior of the elastic member 35. It is understood that the elastic member 35 can have a hollow structure; for example, the elastic member 35 can be a spring. For example, the distance between the trigger 314 of the keycap 31 and the trigger end 21 of the base plate 32 in the Z-axis direction is S2, where S2 > S1. At this time, the trigger 314 of the keycap 31 may still not trigger the trigger end 21 on the base plate 32, and the electrical connection plate 321 of the base plate 32 does not generate an electrical signal.

[0207] Please refer to the following: Figure 10 and Figure 13 In this embodiment, the button assembly 30 is capable of switching between a first state and a second state. During the transition from the first state to the second state, the keycap 31 and the first magnetic element 33 move along a first direction, and the first magnetic element 33 and the second magnetic element 34 repel each other in the first direction.

[0208] Understandably, when the button assembly 30 is in the first state, the user can press the keycap 31 of the button assembly 30 along the first direction, causing the keycap 31 and the first magnetic element 33 to gradually approach the second magnetic element 34 along the first direction, until the first magnetic element 33 covers the second magnetic element 34 and the keycap 31 abuts against the second magnetic element 34. During this process, the first magnetic element 33 and the second magnetic element 34 always maintain repulsion in the first direction, and the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis direction first increases and then decreases.

[0209] Please see Figure 14 , Figure 14 yes Figure 4 The schematic diagram shown is a partial cross-sectional structure of the button assembly 30 cut along CC in some embodiments in a third state.

[0210] In this embodiment, when the button assembly 30 is in the third state, the user presses the keycap 31 along the first direction. At least a portion of the second magnetic element 34 is located within the first space 331. At this time, the repulsive force between the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction is equal to or close to zero.

[0211] For example, the keycap 31 can abut against the second magnetic element 34, such that the second surface 3112 of the keycap 31's pressing plate 311 can contact the first top surface 332 of the second magnetic element 34. When the user presses the keycap 31 along a first direction, the keycap 31 exerts a force on the second magnetic element 34 along the first direction, thereby causing the second magnetic element 34 to compress the elastic element 35 in the first direction, placing the elastic element 35 in a second compressed state. At this time, the length of the elastic element 35 in the first direction is H3, and H3 < H2. That is, the length of the elastic element 35 in the third compressed state is less than its length in the second compressed state.

[0212] For example, the second magnetic element 34 can be disposed around the limiting protrusion 324 of the base plate 32, that is, the limiting protrusion 324 of the base plate 32 can be located within the second space 343 of the second magnetic element 34. In this case, the second space 343 and the first through hole 323 can overlap in the Z-axis direction, which is beneficial for the second magnetic element 34 to further compress the elastic element 35, thereby reducing the height of the elastic element 35 and the button assembly 30 in the Z-axis direction when the button assembly 30 is in the third state, i.e., reducing the compression height of the button assembly 30. It can be understood that when the button assembly 30 is in the third state, the height of the button assembly 30 in the Z-axis direction is the compression height of the button assembly 30. In some other examples, the second magnetic element 34 can be disposed around the first through hole 323. At this time, the first through hole 323 can completely overlap with the second space 343 in the Z-axis direction, and the elastic element 35 can be completely located in the second space 343, which is conducive to the second magnetic element 34 further compressing the elastic element 35, thereby helping to reduce the height of the elastic element 35 and the button assembly 30 in the Z-axis direction in the third state, that is, reducing the compression height of the button assembly 30.

[0213] For example, the trigger 314 of the keycap 31 can pass through the second through hole 344 of the second magnetic member 34, extend into the second space 343 of the second magnetic member 34, and also extend into the interior of the elastic member 35. For example, the distance between the trigger 314 of the keycap 31 and the trigger end 21 of the base plate 32 in the Z-axis direction is S3, where S3 > S2. At this time, the trigger 314 of the keycap 31 may not trigger the trigger end 21 on the base plate 32, and the electrical connection plate 321 of the base plate 32 does not generate an electrical signal. The key assembly 30 can complete the input action and realize the input function of the keyboard 100. It is understood that the trigger 314 of the keycap 31 can directly press the trigger end 21 on the base plate 32, or the trigger end 21 on the base plate 32 can be pressed by other components, or the trigger end 21 on the base plate 32 can be triggered by light triggering. Specifically, this application does not limit the specifics.

[0214] In some embodiments, when the elastic element 35 is in the third compressed state, the edge 312 of the keycap 31 can contact the base plate 32.

[0215] It is understood that, in this embodiment, the inner diameter of the first magnetic element 33 can be larger than the inner diameter of the second magnetic element 34, so that when the button assembly 30 is in the second or third state, the first magnetic element 33 can be fitted over the second magnetic element 34. In other embodiments, the inner diameters of the first magnetic element 33 and the second magnetic element 34 can also be interchanged, that is, the inner diameter of the first magnetic element 33 can be larger than the inner diameter of the second magnetic element 34, so that when the button assembly 30 is in the second or third state, the second magnetic element 34 can be fitted over the first magnetic element 33.

[0216] This application does not impose any limitations on this matter.

[0217] Please refer to the following: Figure 13 and Figure 14 In this embodiment, the button assembly 30 is capable of switching between a second state and a third state. During the transition from the second state to the third state, the keycap 31, the first magnetic element 33, and the second magnetic element 34 all move along a first direction, and the second magnetic element 34 compresses the elastic element 35.

[0218] Understandably, when the key assembly 30 is in the second state, the user can continue to press the keycap 31 of the key assembly 30 along the first direction, causing the second magnetic element 34 to continuously compress the elastic element 35. The keycap 31, the first magnetic element 33, and the second magnetic element 34 gradually approach the base plate 32 along the first direction. The second magnetic element 34 continuously compresses the elastic element 35 until the elastic element 35 is in the third compression state. The elastic element 35 exerts an elastic force on the second magnetic element 34 along the second direction. During this process, the length of the elastic element 35 in the Z-axis direction decreases, that is, the degree of compression of the elastic element 35 increases. The elastic force of the elastic element 35 on the second magnetic element 34 increases with the increase of the degree of compression. The user needs to overcome the elastic force of the elastic element 35 until the trigger element 314 of the keycap 31 contacts the base plate 32.

[0219] Understandably, after the key assembly 30 completes the input action, for example, after the edge 312 of the keycap 31 contacts the base plate 32, the user stops pressing the key assembly 30. At this time, the second magnetic element 34, under the elastic force of the elastic element 35, can drive the keycap 31 and the first magnetic element 33 to move in the second direction, returning to the first state.

[0220] In this embodiment, the travel distance of the keycap 31 and the first magnetic element 33 during the process of the user pressing the button assembly 30 from the first state to the third state is the pressing stroke of the button assembly 30. In this embodiment, by reducing the compression height of the button assembly 30 in the third state, the button stroke of the button assembly 30 can be larger, for example, the button assembly 30 can achieve a pressing stroke greater than 2mm.

[0221] Please see Figure 15 , Figure 15 This is a force-stroke curve of a button assembly 30 provided in an embodiment of this application during the pressing process. Exemplary, Figure 15 The force-stroke curve shown has the horizontal axis representing stroke in millimeters (mm) and the vertical axis representing pressure in Newtons (N). Stroke is the distance traveled by the user pressing the button assembly 30 in the first direction. Pressure is the force applied to the button assembly 30 by the user during the pressing process. It is important to understand that... Figure 15It is a schematic representation of the trend of change in the pressure applied during the pressing process; the specific numerical value of the pressure applied during the pressing process (i.e., the specific value on the vertical axis) is not affected by... Figure 15 Limited by.

[0222] In this embodiment, during the transition of the button assembly 30 from a first state to a second state, the user presses the button assembly 30 along a first direction. Since there is always a magnetic repulsion force between the first magnetic element 33 and the second magnetic element 34 along the Z-axis, and this magnetic repulsion force first increases and then decreases, the user needs to overcome the magnetic repulsion force between the first magnetic element 33 and the second magnetic element 34. This allows the user to experience a pressing sensation (e.g., when pressing the button assembly 30) during the pressing process. Figure 15 (as shown in paragraphs A-B) and paragraph structure (such as...) Figure 15 (As shown in section B-C).

[0223] In this embodiment, during the transition of the key assembly 30 from the second state to the third state, the user continues to press the keycap 31 of the key assembly 30 along the first direction. The second magnetic element 34 continuously compresses the elastic element 35 along the first direction, causing the elastic force of the elastic element 35 on the second magnetic element 34 in the second direction to continuously increase. During this process, the user needs to continuously overcome the elastic force of the elastic element 35, thereby achieving a cushioning sensation during the pressing of the key assembly; furthermore, the user's pressing force on the keycap 31 continuously increases, thus achieving a better cushioning sensation (e.g., ...). Figure 15 (As shown in sections C-D), this is beneficial for improving the tactile experience of users pressing the button component 30.

[0224] It is understood that in this embodiment, the cooperation between the first magnetic element 33 and the second magnetic element 34 provides a pressing feel and a tactile feedback when pressing, while the cooperation between the second magnetic element 34 and the elastic element 35 provides a cushioning feel when pressing, thereby improving the user's tactile experience when pressing the key assembly 30. In this way, the keyboard 100 can have a better typing feel. The user has a better tactile experience when using the keyboard 100.

[0225] Please refer to the following: Figures 16 to 18 , Figure 16 yes Figure 10 The diagram shows a partial structural view of the button assembly 30 from another angle. Figure 17 yes Figure 13 The diagram shows a partial structural view of the button assembly 30 from another angle. Figure 18 yes Figure 14 The diagram shows a partial structural view of the button assembly 30 from another angle. Figures 16 to 18 The diagrams schematically show cross-sectional views of the first magnetic element 33 and the second magnetic element 34 in the first, second, and third states of the button assembly 30, respectively.

[0226] In some embodiments, the first magnetic element 33, the second magnetic element 34, and the elastic element 35 are coaxially arranged. It is understood that the first magnetic element 33, the second magnetic element 34, and the elastic element 35 are all coaxially arranged in the first state, the second state, the third state, and during the switching between different states of the button assembly 30. For example, the first magnetic element 33 has a first central axis A1, the second magnetic element 34 has a second central axis A2, and the elastic element 35 has a third central axis A3. The first central axis A1, the second central axis A2, and the third central axis A3 can all be parallel to the Z-axis direction, and the first central axis A1, the second central axis A2, and the third central axis A3 coincide.

[0227] In this embodiment, the first magnetic element 33 and the second magnetic element 34 are coaxially arranged. On one hand, when the button assembly 30 is in the first state, the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis is relatively large, which is beneficial to achieving a more ideal force-stroke curve and thus a better pressing feel. On the other hand, in the direction perpendicular to the Z-axis, the resultant force of the interaction force between the first magnetic element 33 and the second magnetic element 34 is zero or close to zero, which allows the button assembly 30 to have better motion stability during pressing, that is, the first magnetic element 33 is not easy to tilt relative to the second magnetic element 34. In this way, the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis is also relatively stable, which is beneficial to achieving a more ideal force-stroke curve.

[0228] In this embodiment, the second magnetic element 34 and the elastic element 35 are coaxially arranged. On the one hand, when the second magnetic element 34 presses the elastic element 35 along the first direction, the elastic element 35 can generate a larger elastic force along the second direction, which is beneficial to achieving a more ideal force stroke curve, thereby contributing to a good pressing feel. On the other hand, in the direction perpendicular to the Z-axis, the elastic element 35 is less likely to generate a component force, allowing the button assembly 30 to have better motion stability during pressing.

[0229] Please refer to the following: Figure 17 and Figure 18 In some embodiments, when the button assembly 30 is in the second and third states, the second top surface 345 of the second magnetic element 34 can be located in the first space 331. For example, the second top surface 345 of the second magnetic element 34 is flush with the first top surface 332 of the first magnetic element 33. The first magnetic element 33 and the second magnetic element 34 can overlap to a large extent in the Z-axis direction. This helps to reduce the size of the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction, thereby helping to reduce the compression height of the button assembly 30, which in turn helps to increase the pressing stroke of the button assembly 30 and improve the tactile experience.

[0230] In some embodiments, when the button assembly 30 is in the second and third states, the second bottom surface 346 of the second magnetic element 34 can be located in the first space 331. For example, the second bottom surface 346 of the second magnetic element 34 is flush with the first bottom surface 333 of the first magnetic element 33. The first magnetic element 33 and the second magnetic element 34 can overlap to a large extent in the Z-axis direction. This helps to reduce the size of the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction, thereby helping to reduce the compression height of the button assembly 30, which in turn helps to increase the pressing stroke of the button assembly 30 and improve the tactile experience.

[0231] It is understood that in this embodiment, the thickness of the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction can be the same. When the button assembly 30 is in the second and third states, the first top surface 332 is flush with the second top surface 345, and the first bottom surface 333 is flush with the second bottom surface 346. Thus, when the first magnetic element 33 is fitted onto the second magnetic element 34, the first magnetic element 33 and the second magnetic element 34 can completely overlap in the Z-axis direction, which helps to reduce the compression height of the button assembly 30 and thus helps to increase the pressing stroke of the button assembly 30. Furthermore, the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis direction can be zero, which helps to achieve a more ideal force-stroke curve and improve the pressing feel.

[0232] Please see Figure 19 , Figure 19 yes Figure 17 The diagram shows a cross-sectional structure of the first magnetic component 33 and the second magnetic component 34.

[0233] In this embodiment, when the button assembly 30 is in the second state, the first magnetic element 33 can be sleeved on the second magnetic element 34, and the relative positions of the first magnetic element 33 and the second magnetic element 34 can be implemented in different ways. For example... Figure 19 As shown in (a), the second top surface 345 of the second magnetic element 34 can be located in the first space 331. For example, along the first direction, the first top surface 332 of the first magnetic element 33 is recessed relative to the second top surface 345 of the second magnetic element 34. Figure 19 As shown in (b), the second top surface 345 of the second magnetic element 34 is located outside the first space 331. It can be understood that, along the first direction, the second top surface 345 of the second magnetic element 34 protrudes beyond the first top surface 332 of the first magnetic element 33. Figure 19 As shown in (c), the second bottom surface 346 of the second magnetic element 34 can be located in the first space 331. For example, along the first direction, the first bottom surface 333 of the first magnetic element 33 protrudes beyond the second bottom surface 346 of the second magnetic element 34. Figure 19As shown in (d), the second bottom surface 346 of the second magnetic element 34 is located outside the first space 331. It can be understood that, along the first direction, the second bottom surface 346 of the second magnetic element 34 protrudes beyond the first bottom surface 333 of the first magnetic element 33. At this time, the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis can approach zero.

[0234] It is understandable that when the button assembly 30 is in the second and third states, the relative positional relationship between the first magnetic element 33 and the second magnetic element 34 can be the same or similar. Therefore, when the button assembly 30 is in the third state, the relative positional relationship between the first magnetic element 33 and the second magnetic element 34 can be found in [reference needed]. Figure 19 The relevant descriptions are omitted here.

[0235] It is understood that, in the embodiments of this application, when the button assembly 30 is in the second and third states, there is no strict limitation on the positional relationship between the first magnetic element 33 and the second magnetic element 34. At least a portion of the second magnetic element 34 is located within the first space 331 of the first magnetic element 33, and the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element along the Z-axis direction is close to or equal to zero. This helps to reduce the manufacturing cost of the button assembly 30, simplify the assembly process of the button assembly 30, and improve production efficiency.

[0236] Please refer to the following: Figure 20A and Figure 20B , Figure 20A yes Figure 5 The diagram shown is a structural schematic of the first support member 36 in some embodiments. Figure 20B yes Figure 20A The diagram shows the structure of the first support member 36 at another angle.

[0237] In some embodiments, the first support member 36 includes a first rotating end 361, a first movable end 362, and a first connecting portion 363. The first connecting portion 363 connects the first movable end 362 and the first rotating end 361. Exemplarily, the first support member 36 can generally be a frame. The first support member 36 can enclose a first receiving space 360. For example, the first support member 36 can be a rectangular frame. In this case, the first support member 36 may include a first side 36a, a second side 36b, a third side 36c, and a fourth side 36d connected in sequence. The first side 36a to the fourth side 36d of the first support member 36 together enclose the first receiving space 360.

[0238] It is understood that the first movable end 362 may include the first side 36a of the first support member 36. The first rotating end 361 may include the third side 36c of the first support member 36. The first connecting portion 363 may include the second side 36b and the fourth side 36d of the first support member 36.

[0239] For example, the first support member 36 includes a first surface 364 and a second surface 365 disposed opposite to each other. The first support member 36 also includes a first side surface 366 and a second side surface 367 disposed opposite to each other, the first side surface 366 and the second side surface 367 being connected between the first surface 364 and the second surface 365. For example, the first rotating end 361 of the first support member 36 is provided with a first clearance through hole 3611 and a second clearance through hole 3612. Both the first clearance through hole 3611 and the second clearance through hole 3612 penetrate through the first surface 364 and the second surface 365 of the first support member 36. For example, the first rotating end 361 is also provided with a first rotating shaft 3613 and a second rotating shaft 3614. The first rotating shaft 3613 may be located within the first clearance through hole 3611. The second rotating shaft 3614 may be located within the second clearance through hole 3612.

[0240] For example, the first movable end 362 of the first support member 36 is provided with a third clearance through hole 3621 and a fourth clearance through hole 3622. Both the third clearance through hole 3621 and the fourth clearance through hole 3622 penetrate the first surface 364 and the second surface 365 of the first support member 36. For example, the first rotating end 361 is also provided with a first movable portion 3623 and a second movable portion 3624. At least a portion of the first movable portion 3623 may be located within the third clearance through hole 3621. At least a portion of the second movable portion 3624 may be located within the fourth clearance through hole 3622.

[0241] For example, the first connecting portion 363 of the first support member 36 includes a third pivot 3631 and a fourth pivot 3632. Both the third pivot 3631 and the fourth pivot 3632 face away from the first receiving space 360. The third pivot 3631 may protrude from the first side surface 366 of the first support member 36.

[0242] The fourth pivot 3632 may protrude from the second side 367 of the first support member 36.

[0243] In some embodiments, the first support member 36 is further provided with a plurality of clearance grooves 368. The openings of the clearance grooves 368 are located on the second surface 365 of the first support member 36. It is understood that the clearance grooves 368 of the first support member 36 can be used to provide clearance space for other components of the key assembly 30 or other components of the keyboard 100, thereby preventing interference between other components of the key assembly 30 or other components of the keyboard 100 and the keycaps 31. This prevents misalignment, wear, or even breakage caused by collisions between other components of the key assembly 30 or other components of the keyboard 100 and the keycaps 31, thereby extending the service life of the key assembly 30. Furthermore, Figure 20B Some clearance slots 368 are shown only schematically. This application does not make specific limitations on the number, shape, size and position of clearance slots 368, for example, they can be designed according to the specific shape and size of the product.

[0244] Please refer to the following: Figure 21A and Figure 21B , Figure 21A yes Figure 5 The diagram shown is a structural schematic of the second support member 37 in some embodiments. Figure 21B yes Figure 21A The diagram shows the structure of the second support member 37 at another angle.

[0245] In some embodiments, the second support member 37 includes a second rotating end 371, a second movable end 372, and a second connecting portion 373. The second connecting portion 373 connects the second movable end 372 and the second rotating end 371. Exemplarily, the second support member 37 can generally be a frame. The second support member 37 can enclose a second receiving space 370. For example, the second support member 37 can be a rectangular frame. In this case, the second support member 37 may include a first side 37a, a second side 37b, a third side 37c, and a fourth side 37d connected in sequence. The first side 37a to the fourth side 37d of the first support member 36 together enclose the second receiving space 370.

[0246] It is understood that the second movable end 372 may include the first side 37a of the second support member 37. The second rotating end 371 may include the third side 37c of the second support member 37. The second connecting portion 373 may include the second side 37b and the fourth side 37d of the second support member 37.

[0247] For example, the second support member 37 includes a first surface 374 and a second surface 375 disposed opposite to each other. The second support member 37 also includes a first side surface 376 and a second side surface 377 disposed opposite to each other, the first side surface 376 and the second side surface 377 being connected between the first surface 374 and the second surface 375. For example, the second rotating end 371 of the second support member 37 is provided with a first rotating hole 3711 and a second rotating hole 3712 disposed at intervals. Both the first rotating hole 3711 and the second rotating hole 3712 penetrate through the first surface 374 and the second surface 375 of the second support member 37.

[0248] For example, the second rotating end 371 of the second support member 37 is further provided with a first rotating groove 3713 and a second rotating groove 3714. The openings of the first rotating groove 3713 and the second rotating groove 3714 are both located on the first surface 374 of the second support member 37. The first rotating groove 3713 can connect to the first rotating hole 3711. The second rotating groove 3714 can connect to the second rotating hole 3712. For example, a portion of the inner wall of the first rotating groove 3713 can be an arc surface, and at least a portion of the arc surface faces the second movable end 372. A portion of the inner wall of the second rotating groove 3714 can be an arc surface, and at least a portion of the arc surface faces the second movable end 372.

[0249] For example, the second movable end 372 of the second support member 37 is provided with a first clearance space 3721 and a second clearance space 3722. Both the first clearance space 3721 and the second clearance space 3722 penetrate the first surface 374 and the second surface 375 of the second support member 37. Specifically, the first clearance space 3721 also penetrates the first side surface 376 of the second support member 37 and extends to the side of the second movable end 372 away from the second rotating end 371. The second clearance space 3722 also penetrates the second side surface 377 of the second support member 37 and extends to the side of the second movable end 372 away from the second rotating end 371.

[0250] For example, the second movable end 372 of the second support member 37 is further provided with a first protrusion 3723 and a second protrusion 3724. The first protrusion 3723 may protrude from the first side surface 376 of the second support member 37. The second protrusion 3724 may protrude from the second side surface 377 of the second support member 37. In this case, the first protrusion 3723 and the second protrusion 3724 may be arranged opposite to each other in the X-axis direction.

[0251] For example, the second connecting portion 373 of the second support member 37 may be provided with a first pivot hole 3731 and a second pivot hole 3732. The first pivot hole 3731 and the second pivot hole 3732 are disposed opposite to each other and both communicate with the second receiving space 370. For example, both the first pivot hole 3731 and the second pivot hole 3732 can be circular blind holes. In some other examples, the first pivot hole 3731 and the second pivot hole 3732 can also be through holes. This application does not limit this.

[0252] In some embodiments, the second support member 37 is further provided with a plurality of clearance grooves 378. The openings of the clearance grooves 378 are located on the second surface 375 of the second support member 37. It is understood that the clearance grooves 378 of the second support member 37 can be used to provide clearance space for other components of the key assembly 30 or other components of the keyboard 100, thereby preventing interference between other components of the key assembly 30 or other components of the keyboard 100 and the keycap 31, that is, preventing misalignment, wear, or even breakage caused by collision between other components of the key assembly 30 or other components of the keyboard 100 and the keycap 31, thereby extending the service life of the key assembly 30. In addition, Figure 20B Some clearance slots 378 are shown only schematically. This application does not make specific limitations on the number, shape, size and position of clearance slots 378, for example, they can be designed according to the specific shape and size of the product.

[0253] Please refer to the following: Figure 22 and Figure 23 , Figure 22 yes Figure 5 The diagram shows a partial structural representation of the button assembly 30 in some embodiments. Figure 23 yes Figure 22 The diagram shows a partial cross-sectional view of the button assembly 30 taken along point DD. For example, Figure 22 and Figure 23 The main illustration shows the assembly structure of the first support member 36 and the second support member 37 of the button assembly 30 in some embodiments.

[0254] In some embodiments, at least a portion of the first support member 36 may be located within the second receiving space 370 of the second support member. It is understood that, projected along the first direction, the projection of the second receiving space 370 of the second support member 37 overlaps the projection of the first support member 36. The first connecting portion 363 of the first support member 36 is rotatably connected to the second connecting portion 373 of the second support member 37. The first connecting portion 363 and the second connecting portion 373 are arranged at an angle. Exemplarily, the angle between the first connecting portion 363 and the second connecting portion 373 can be in the range of 120° to 180°. For example, the first angle can be 120°, 125°, 145°, 150°, 160°, 170°, or 180°, etc.

[0255] For example, at least a portion of the third rotating shaft 3631 of the first connecting portion 363 may be located within the first rotating shaft hole 3731 of the second connecting portion 373, and the third rotating shaft 3631 may rotate within the first rotating shaft hole 3731. At least a portion of the fourth rotating shaft 3632 of the first connecting portion 363 may be located within the second rotating shaft hole 3732, and the fourth rotating shaft 3632 may rotate within the second rotating shaft hole 3732. Thus, through the cooperation of the third rotating shaft 3631 with the first rotating shaft hole 3731 and the fourth rotating shaft 3632 with the second rotating shaft hole 3732, the first support member 36 may rotate relative to the second support member 37. It is understood that, in the embodiments of this application, the connection position of the first connecting portion 363 and the second connecting portion 373 may be the center position of the first connecting portion 363 and the second connecting portion 373, or it may be other positions of the first connecting portion 363 and the second connecting portion 373. This application does not limit this.

[0256] In some other embodiments, the structural form of the third rotating shaft 3631 of the first connecting portion 363 and the structural form of the first rotating shaft hole 3731 of the second connecting portion 373 can be interchanged. That is, the first connecting portion 363 can be provided with a rotating groove structure or a rotating shaft hole structure, and the second connecting portion 373 can be provided with a rotating shaft or a protrusion structure. Similarly, the structural form of the fourth rotating shaft 3632 of the first connecting portion 363 and the structural form of the second rotating shaft hole 3732 of the second connecting portion 373 can also be interchanged.

[0257] Please refer to the following: Figure 24 and Figure 25 , Figure 24 yes Figure 4 The diagram shown is a partial structural schematic of the button assembly 30 in some embodiments. Figure 25 yes Figure 4 The schematic diagram shown is a partial cross-sectional view of the button assembly 30 taken along EE in some embodiments. For example, Figure 24 The diagram mainly shows the assembly structure of the keycap 31, the first magnetic component 33, the first support component 36, and the second support component 37.

[0258] In some embodiments, the first support member 36 may be disposed around the first magnetic member 33. The first rotating end 361 of the first support member 36 is rotatably connected to the keycap 31. Exemplarily, the first pivot 3613 of the first rotating end 361 of the first support member 36 may pass through the first rotating groove 3713 of the first limiting block 3161 of the keycap 31. The first pivot 3613 may rotate about the X-axis within the first rotating groove 3713. At this time, at least a portion of the first limiting block 3161 of the keycap 31 may extend into the first clearance through hole 3611 of the first rotating end 361 of the first support member 36. It is understood that the first rotating groove 3713 may limit the displacement of the first rotating end 361 of the first support member 36 in the Y-axis direction. Furthermore, the cooperation between the first clearance through hole 3611 and the first limiting block 3161 may also limit the displacement of the first rotating end 361 of the first support member 36 in the X-axis direction.

[0259] For example, the second pivot 3614 of the first rotating end 361 of the first support member 36 can pass through the second rotating groove 3714 of the second limiting block 3162 of the keycap 31. The second pivot 3614 can rotate about the X-axis within the second rotating groove 3714. At this time, at least a portion of the second limiting block 3162 of the keycap 31 can extend into the second clearance through hole 3612 of the first rotating end 361 of the first support member 36. It is understood that the second rotating groove 3714 can limit the displacement of the first rotating end 361 of the first support member 36 in the Y-axis direction. In addition, the cooperation between the second clearance through hole 3612 and the second limiting block 3162 can also limit the displacement of the first rotating end 361 of the first support member 36 in the X-axis direction.

[0260] For example, the first stop 3171 may be located on the side of the first rotating end 361 facing away from the first receiving space 360 ​​and abut against the first rotating end 361. It is understood that the first stop 3171 may be used to limit the displacement of the first rotating end 361 in the positive Y-axis direction.

[0261] It is understood that, in the embodiments of this application, the first rotating end 361 of the first support member 36 can rotate relative to the keycap 31 around the X-axis, and can avoid detaching from the keycap 31 along the X-axis direction and along the Y-axis direction.

[0262] Please refer to the following: Figure 25 and Figure 26 , Figure 26 yes Figure 4 The diagram shows a partial structural representation of the button assembly 30 in some embodiments. Exemplary, Figure 26 The diagram mainly shows the assembly structure of the base plate 32, the second magnetic component 34, the elastic component 35, the first support component 36, and the second support component 37.

[0263] In some embodiments, the first support member 36 may be disposed around the second magnetic member 34 and the elastic member 35. The first movable end 362 of the first support member 36 is movably connected to the base plate 32. Exemplarily, a portion of the first movable end 362 may be located within a clearance space 327 of the base plate 32. In this case, the clearance space 327 can be used to allow the first movable end 362 of the first support member 36 to pass. The first limiting portion 3261 of the base plate 32 may extend into the third clearance through hole 3621 of the first movable end 362. It is understood that the cooperation between the third clearance through hole 3621 and the first limiting portion 3261 can be used to limit the displacement of the first movable end 362 of the first support member 36 in the X-axis direction and in the negative Y-axis direction. Exemplarily, the first movable portion 3623 of the first movable end 362 may be located within the first clearance hole 3251 of the base plate 32. The first movable portion 3623 of the first movable end 362 of the first support member 36 may abut against the first limiting portion 3261 of the base plate 32. The first movable part 3623 can slide and rotate within the first clearance hole 3251. For example, the first movable part 3623 can slide along the Y-axis and rotate around the X-axis. In addition, the first limiting part 3261 can be used to limit the displacement of the first movable part 3623 in the positive Y-axis direction.

[0264] For example, the second limiting portion 3262 of the base plate 32 can extend into the fourth clearance through hole 3622 of the first movable end 362. It is understood that the cooperation between the fourth clearance through hole 3622 and the second limiting portion 3262 can be used to limit the displacement of the first movable end 362 of the first support member 36 in the X-axis direction and in the negative Y-axis direction. For example, the second movable portion 3624 of the first movable end 362 can be located within the second clearance hole 3252 of the base plate 32. The second movable portion 3624 of the first movable end 362 of the first support member 36 can abut against the second limiting portion 3262 of the base plate 32. The second movable portion 3624 can slide and rotate within the second clearance hole 3252; for example, the second movable portion 3624 can slide along the Y-axis direction and rotate about the X-axis. Furthermore, the second limiting portion 3262 can be used to limit the displacement of the second movable portion 3624 in the positive Y-axis direction.

[0265] It is understood that, in the embodiments of this application, the first movable end 362 of the first support member 36 can slide relative to the base plate 32 along the Y-axis direction and rotate around the X-axis, and can avoid detaching from the base plate 32 along the X-axis direction and along the Y-axis direction.

[0266] Please refer to the following: Figure 27A and Figure 27B , Figure 27A yes Figure 4 The diagram shown is a partial structural schematic of the button assembly 30 in some embodiments. Figure 27B yes Figure 4 The diagram shows a partial cross-sectional view of the button assembly 30 taken along FF in some embodiments. For example, Figure 27A The diagram mainly shows the assembly structure of the keycap 31, the first magnetic component 33, the first support component 36, and the second support component 37.

[0267] In some embodiments, the second movable end 372 of the second support member 37 is movably connected to the keycap 31. Exemplarily, at least a portion of the first protrusion 3723 of the second movable end 372 of the second support member 37 may be located within the first guide groove 3153 of the first guide block 3151 of the keycap 31. The first protrusion 3723 can slide and rotate within the first guide groove 3153; for example, the first protrusion 3723 can slide along the Y-axis and rotate about the X-axis. At this time, at least a portion of the first guide block 3151 of the keycap 31 may be located within the first clearance space 3721 of the second movable end 372 of the second support member 37. It is understood that the inner wall of the first guide groove 3153 of the keycap 31 can be used to limit the displacement of the first protrusion 3723 in the X-axis direction and in the positive Y-axis direction. Furthermore, the cooperation between the first guide block 3151 and the first clearance space 3721 can also limit the displacement of the second movable end 372 of the second support member 37 in the X-axis direction and in the negative Y-axis direction.

[0268] For example, at least a portion of the second protrusion 3724 of the second movable end 372 of the second support member 37 can be located within the second guide groove 3154 of the second guide block 3152 of the keycap 31. The second protrusion 3724 can slide and rotate within the second guide groove 3154; for example, the second protrusion 3724 can slide along the Y-axis and rotate about the X-axis. At this time, at least a portion of the second guide block 3152 of the keycap 31 can be located within the second clearance space 3722 of the second movable end 372 of the second support member 37. It is understood that the inner wall of the second guide groove 3154 of the keycap 31 can be used to limit the displacement of the second protrusion 3724 in the X-axis direction and in the positive Y-axis direction. Furthermore, the cooperation between the second guide block 3152 and the second clearance space 3722 can also limit the displacement of the second movable end 372 of the second support member 37 in the X-axis direction and in the negative Y-axis direction.

[0269] It is understood that, in the embodiments of this application, the second rotating end 371 of the second support member 37 can slide relative to the keycap 31 along the Y-axis direction and rotate around the X-axis, and can avoid detaching from the keycap 31 along the X-axis direction and along the Y-axis direction.

[0270] In some embodiments, the second stop 3172 of the keycap 31 may be located on the side of the second movable end 372 of the second support member 37 facing away from the second receiving space 370. It is understood that the second stop 3172 can be used to abut against the second movable end 372 to limit the displacement of the second movable end 372 in the negative Y-axis direction. For example, when the key assembly 30 is in the third state, the second stop 3172 of the keycap 31 may abut against the second movable end 372 of the second support member 37. At this time, the second stop 3172 can limit the movement of the second movable end 372 of the second support member 37 relative to the keycap 31 in the negative Y-axis direction.

[0271] Please refer to the following: Figure 27B and Figure 28 , Figure 28 yes Figure 4 The diagram shows a partial structural representation of the button assembly 30 in some embodiments. Exemplary, Figure 28 The diagram mainly shows the assembly structure of the base plate 32, the second magnetic component 34, the elastic component 35, the first support component 36, and the second support component 37.

[0272] In some embodiments, the second rotating end 371 of the second support member 37 is rotatably connected to the base plate 32. For example, a portion of the second rotating end 371 may be located within the clearance space 327 of the base plate 32. In this case, the clearance space 327 can be used to avoid the second rotating end 371 of the second support member 37. The third limiting portion 3263 of the base plate 32 may extend into the first rotating hole 3711 of the second rotating end 371, and a portion of the third limiting portion 3263 may be located within the first rotating groove 3713 and abut against the inner wall of the first rotating groove 3713. For example, the third limiting portion 3263 may abut against the arcuate surface of the first rotating groove 3713. The third limiting portion 3263 may rotate within the first rotating hole 3711 and the first rotating groove 3713; for example, the third limiting portion 3263 may rotate about the X-axis. Furthermore, the cooperation between the first rotating hole 3711 and the first rotating groove 3713 can also limit the displacement of the second rotating end 371 of the second support member 37 in the X-axis direction and in the Y-axis direction.

[0273] For example, the fourth limiting portion 3264 of the base plate 32 can extend into the second rotating hole 3712 of the second rotating end 371, and a portion of the fourth limiting portion 3264 can be located within the second rotating groove 3714 and abut against the inner wall of the second rotating groove 3714. For example, the fourth limiting portion 3264 can abut against the arc surface of the second rotating groove 3714. The fourth limiting portion 3264 can rotate within the second rotating hole 3712 and the second rotating groove 3714, for example, the fourth limiting portion 3264 can rotate about the X-axis. Furthermore, the cooperation of the second rotating hole 3712 and the second rotating groove 3714 can also limit the displacement of the second rotating end 371 of the second support member 37 in the X-axis direction and in the Y-axis direction.

[0274] It is understood that, in the embodiments of this application, the second rotating end 371 of the second support member 37 can rotate relative to the base plate 32 around the X-axis, and can avoid detaching from the base plate 32 along the X-axis direction and along the Y-axis direction.

[0275] Please see Figure 29 , Figure 29 yes Figure 4 The button assembly 30 shown is a front view of its first state in some embodiments.

[0276] In some embodiments, when the button assembly 30 is in the first state, the first support member 36 and the second support member 37 can be arranged crosswise. In this case, the first support member 36 and the second support member 37 can be in a "scissor" shape. The angle between the first connecting portion 363 of the first support member 36 and the second connecting portion 373 of the second support member 37 is a first angle. The first angle can be in the range of 120° to 140°. For example, the first angle can be 120°, 125°, 145°, or 140°, etc.

[0277] It is understandable that when the key assembly 30 is in the first state, the first movable end 362 of the first support member 36 can abut against the keycap 31 (see [link]). Figure 25 The second movable end 372 of the second support member 37 can abut against the base plate 32 (see [link]). Figure 27B This restricts the sliding and rotation of the first support member 36 relative to the base plate 32 and the sliding and rotation of the second support member 37 relative to the keycap 31.

[0278] Please see Figure 30 , Figure 30 yes Figure 4 The button assembly 30 shown is a front view of the second state in some embodiments.

[0279] In some embodiments, when the button assembly 30 is in the second state, the first support member 36 and the second support member 37 can be arranged crosswise. In this case, the first support member 36 and the second support member 37 can be in a "scissor" shape. The included angle between the first connecting portion 363 of the first support member 36 and the second connecting portion 373 of the second support member 37 is a second angle, which is greater than the first angle. The second angle can be in the range of 140° to 160°. For example, the first angle can be 145°, 150°, 155°, or 160°, etc.

[0280] It is understandable that when the key assembly 30 is in the second state, the first movable end 362 of the first support member 36 can abut against the keycap 31, and the second movable end 372 of the second support member 37 can abut against the base plate 32, thereby restricting the sliding and rotation of the first support member 36 relative to the base plate 32 and the sliding and rotation of the second support member 37 relative to the keycap 31.

[0281] Please refer to the following: Figure 27A and Figure 28 In some embodiments, when projected along the first direction (i.e., along the Z-axis), the projection of the first accommodating space 360 ​​on a plane perpendicular to the first direction (i.e., the XY plane) can cover the projections of the first magnetic element 33, the second magnetic element 34, and the elastic element 35. Thus, during the transition of the button assembly 30 from the first state to the second state, the first accommodating space 360 ​​of the first support member 36 can be used to avoid interference between the first magnetic element 33, the second magnetic element 34, and the elastic element 35 and the first support member 36. This prevents misalignment, wear, or even breakage of the first magnetic element 33, the second magnetic element 34, and the elastic element 35, thus improving the reliability of the button assembly 30.

[0282] Please refer to the following: Figure 29 and Figure 30When a user presses the button assembly 30 along a first direction, the button assembly 30 can transition from a first state to a second state. During the transition from the first state to the second state, the keycap 31 exerts a force along the first direction on the first support member 36 and the second support member 37. This causes the first rotating end 361 of the first support member 36 to rotate relative to the keycap 31 and the first movable end 362 to slide relative to the base plate 32 (e.g., the first movable end 362 can slide relative to the base plate 32 along the negative Y-axis) and rotate. Simultaneously, the second rotating end 371 of the second support member 37 rotates relative to the base plate 32 and the second movable end 372 can slide relative to the keycap 31 (e.g., the first movable end 362 can slide relative to the base plate 32 along the positive Y-axis) and rotate. As a result, the first rotating end 361 of the first support member 36 and the second movable end 372 of the second support member 37 gradually approach the base plate 32 along the first direction. That is, the height of the first support member 36 and the second support member 37 in the Z-axis direction decreases, and thus the keycap 31 can gradually approach the base plate 32 along the first direction. During this process, the first connecting part 363 and the second connecting part 373 of the first support member 36 can rotate relative to each other, and the included angle between the first connecting part 363 and the second connecting part 373 gradually increases.

[0283] Please refer to the following: Figure 31A and Figure 31B , Figure 31A yes Figure 4 The button assembly 30 shown is a front view in some embodiments when it is in the third state. Figure 31B yes Figure 31A The diagram shows the structure of the first support member 36 and the second support member 37 of the button assembly 30 in some embodiments.

[0284] In some embodiments, when the button assembly 30 is in the third state, the included angle between the first connecting portion 363 of the first support member 36 and the second connecting portion 373 of the second support member 37 is a third angle. The third angle is greater than the second angle. For example, the second angle can be in the range of 160° to 180°. For instance, the third angle can be 160°, 165°, 170°, 175°, or 180°, etc. Figure 31B As shown, when the angle between the first connecting part 363 and the second connecting part 373 is 180°, the second support member 37 can surround the first support member 36.

[0285] Understandably, when the key assembly 30 is in the third state, the first movable end 362 of the first support member 36 can abut against the keycap 31, and the second movable end 372 of the second support member 37 can abut against the base plate 32, thereby restricting the sliding and rotation of the first support member 36 relative to the base plate 32 and the sliding and rotation of the second support member 37 relative to the keycap 31.

[0286] Please refer to the following: Figure 30 and Figure 31A The user continues to press the button assembly 30 along the first direction, and the button assembly 30 can transition from the second state to the third state. During the transition from the second state to the third state, the keycap 31 exerts a force along the first direction on the first support member 36 and the second support member 37, causing the height of the first support member 36 and the second support member 37 in the Z-axis direction to continue to decrease, so that the keycap 31 can gradually move closer to the base plate 32 along the first direction. During this process, the first connecting portion 363 of the first support member 36 and the second connecting portion 373 of the second support member 37 can continue to rotate relative to each other, and the included angle between the first connecting portion 363 and the second connecting portion 373 gradually increases. In addition, during this process, the first receiving space 360 ​​of the first support member 36 can be used to avoid the first magnetic member 33, the second magnetic member 34 and the elastic member 35, thereby avoiding interference between the first magnetic member 33, the second magnetic member 34 and the elastic member 35 and the first support member 36, and thus preventing the first magnetic member 33, the second magnetic member 34 and the elastic member 35 from misalignment, wear or even breakage, which is beneficial to the reliability of the button assembly 30.

[0287] Please refer to the following: Figure 32 and Figure 33 , Figure 32 yes Figure 4 The schematic diagram shown is a structural representation of the button assembly 30 in some other embodiments. Figure 33 yes Figure 32 The button assembly 30 shown is a partial exploded view in some embodiments. Figure 33 The button component 30 shown may include most of the technical content of the previous embodiments. The following mainly describes the differences between the two, and the most common aspects of the two will not be repeated.

[0288] In this embodiment, the button assembly 30 may include a keycap 31, a base plate 32, a first magnetic element 33, a second magnetic element 34, an elastic element 35, a first support element 36, and a second support element 37. The keycap 31 may include a pressing plate 311 and a frame 312. The pressing plate 311 includes a first surface 3111 and a second surface 3112 facing away from each other. The frame 312 is fixed to the second surface 3112 of the pressing plate 311. The pressing plate 311 and the frame 312 form a first receiving groove 310.

[0289] For example, the keycap 31 may also include a first guide rail block 3191, a second guide rail block 3192, a third guide rail block 3193, and a fourth guide rail block 3194. The first guide rail block 3191, the second guide rail block 3192, the third guide rail block 3193, and the fourth guide rail block 3194 all protrude from the second surface 3112 of the press plate 311 and are all located within the first receiving groove 310.

[0290] In addition, the first guide rail block 3191, the second guide rail block 3192, the third guide rail block 3193, and the fourth guide rail block 3194 are respectively provided with a first guide groove 3195, a second guide groove 3196, a third guide groove 3197, and a fourth guide groove 3198. The first guide groove 3195 of the first guide rail block 3191 is opposite to the second guide groove 3196 of the second guide rail block 3192. The third guide groove 3197 of the third guide rail block 3193 is opposite to the fourth guide groove 3198 of the fourth guide rail block 3194. For example, the first guide groove 3195, the second guide groove 3196, the third guide groove 3197, and the fourth guide groove 3198 can all be strip-shaped.

[0291] In this embodiment, the keycap 31 may further include a first stop 3173 and a second stop 3174. The first stop 3173 and the second stop 3174 can be cuboids, cylinders, or other shapes; this embodiment uses cuboids as an example. Both the first stop 3173 and the second stop 3174 protrude from the second surface 3112 of the press plate 311 and are located within the first receiving groove 310.

When the multiple magnetic portions of the first magnetic element 33 and the multiple magnetic portions of the second magnetic element 34 are radially magnetized, the inner surfaces of the corresponding magnetic portions of the first magnetic element 33 and the second magnetic element 34 have opposite magnetic poles.

[0310] Please see Figure 37 , Figure 37 yes Figure 33 The diagram shows the structure of the first support member 36 and the second support member 37.

[0311] In this embodiment, the first support member 36 may include a first rotating end 361A, a first movable end 362A, and a first connecting portion 363A. The first connecting portion 363A connects the first movable end 362A and the first rotating end 361A.

[0312] For example, the first support member 36 is provided with a first clearance hole 3601. The first clearance hole 3601 passes through the first rotating end 361A of the first support member 36. The first clearance hole 3601 can extend from the first rotating end 361A of the first support member 36 to the first connecting portion 363A of the first support member 36. It is understood that the first clearance hole 3601 can divide the first rotating end 361A into two spaced-apart and opposite parts, and can also divide the first connecting portion 363A into two spaced-apart and opposite parts. In other examples, the first clearance hole 3601 may also be provided only at the first rotating end 361A of the first support member 36.

The first rotating portion 3615 and the second rotating portion 3616 may be spaced apart and arranged opposite to each other. For example, the first rotating portion 3615 may include a first sub-rotating portion 3615a and a second sub-rotating portion 3615b. The second sub-rotating portion 3615b is located on the side of the first sub-rotating portion 3615a closer to the second rotating portion 3616. There is a height difference between the first sub-rotating portion 3615a and the second sub-rotating portion 3615b. For example, the second rotating portion 3616 may include a third sub-rotating portion 3616a and a fourth sub-rotating portion 3616b. The third sub-rotating portion 3616a is located on the side of the fourth sub-rotating portion 3616b closer to the first rotating portion 3615. There is a height difference between the third sub-rotating part 3616a and the fourth sub-rotating part 3616b.

[0314] For example, the first support member 36 may include a first side 3661 and a second side 3662 disposed opposite to each other. A first pivot portion 3617 may protrude from the first side 3661 of the first support member 36. A second pivot portion 3618 may protrude from the second side 3662 of the first support member 36. It is understood that the first pivot portion 3617 and the second pivot portion 3618 may be disposed opposite to each other.

[0315] For example, the first abutment portion 3619 can be a block structure. The first abutment portion 3619 can protrude from the first side surface 3661 of the first support member 36 and be spaced apart from the first rotating shaft portion 3617. For example, the first abutment portion 3619 can be located on the side of the first rotating shaft portion 3617 away from the first movable end 362A of the first support member 36. It is understood that the first abutment portion 3619 connects to the first sub-rotating portion 3615a.

[0316] In some embodiments, the first movable end 362A of the first support member 36 may include a first body portion 3625, a first movable portion 3626, and a second movable portion 3627. The first body portion 3625 may be plate-shaped. The first movable portion 3626 and the second movable portion 3627 may be block-shaped structures. The first movable portion 3626 may protrude from the first side surface 3661 of the first support member 36. The second movable portion 3627 may protrude from the second side surface 3662 of the first support member 36.

[0317] In this embodiment, the second support member 37 may include a second rotating end 371A, a second movable end 372A, and a second connecting portion 373A. The second connecting portion 373A connects the second movable end 372A and the second rotating end 371A.

[0318] For example, the second support member 37 is provided with a second clearance hole 3701. The second clearance hole 3701 passes through the second rotating end 371A of the second support member 37. The second clearance hole 3701 can extend from the second rotating end 371A of the second support member 37 to the second connecting portion 373A of the second support member 37. It is understood that the second clearance hole 3701 can divide the second rotating end 371A into two spaced and opposite parts, and can also divide the second connecting portion 373A into two spaced and opposite parts. In other examples, the second clearance hole 3701 may also be provided only at the second rotating end 371A of the second support member 37.

[0319] For example, the second rotating end 371A of the second support member 37 may be provided with a third rotating portion 3715, a fourth rotating portion 3716, a third rotating shaft portion 3717, a fourth rotating shaft portion 3718, and a second abutting portion 3719. The third rotating portion 3715 and the fourth rotating portion 3716 may be spaced apart and arranged opposite to each other. For example, the third rotating portion 3715 may include a first sub-rotating portion 3715a and a second sub-rotating portion 3715b. The second sub-rotating portion 3715b is located on the side of the first sub-rotating portion 3715a closer to the fourth rotating portion 3716. There is a height difference between the first sub-rotating portion 3715a and the second sub-rotating portion 3715b. For example, the fourth rotating portion 3716 may include a third sub-rotating portion 3716a and a fourth sub-rotating portion 3716b. The third sub-rotating portion 3716a is located on the side of the fourth sub-rotating portion 3716b closer to the third rotating portion 3715. There is a height difference between the third sub-rotating part 3716a and the fourth sub-rotating part 3716b.

[0320] For example, the second support member 37 may include a first side 3761 and a second side 3762 disposed opposite to each other. A third pivot portion 3717 may protrude from the first side 3761 of the second support member 37. A fourth pivot portion 3718 may protrude from the second side 3762 of the second support member 37. It is understood that the third pivot portion 3717 and the fourth pivot portion 3718 may be disposed opposite to each other.

[0321] For example, the second abutment portion 3719 can be a block structure. The second abutment portion 3719 can protrude from the first side 3761 of the second support member 37 and be spaced apart from the third pivot portion 3717. For instance, the second abutment portion 3719 can be located on the side of the fourth pivot portion 3718 away from the second movable end 372A of the second support member 37. It is understood that the second abutment portion 3719 connects to the fourth sub-rotating portion 3716b.

[0322] In some embodiments, the second movable end 372A of the second support member 37 may include a second body portion 3725, a third movable portion 3726, and a fourth movable portion 3727. The second body portion 3725 may be plate-shaped. The third movable portion 3726 and the fourth movable portion 3727 may be block-shaped structures. The third movable portion 3726 may protrude from the first side surface 3761 of the second support member 37. The fourth movable portion 3727 may protrude from the second side surface 3762 of the second support member 37.

[0323] It is understood that the second support member 37 and the first support member 36 in this embodiment may have the same or similar structure, be symmetrical or partially symmetrical, or have different structures. In this embodiment, the second support member 37 and the first support member 36 have the same structure. The basic design of the component structure of the second support member 37, the design of the connection relationship between components, and the design of other connection relationships besides components and assemblies can all refer to the relevant scheme of the first support member 36. At the same time, slight differences are allowed between the second support member 37 and the first support member 36 in the detailed structure or positional arrangement of components. Specific details will not be elaborated here.

[0324] It is understood that although this embodiment describes one structure of the first rotating portion 3615 and the second rotating portion 3616 of the first rotating end 361A of the first support member 36, and the third rotating portion 3715 and the fourth rotating portion 3716 of the second rotating end 371A of the second support member 37, other structures may be adopted in other embodiments. For example, the shape and size of the first rotating portion 3615 and the second rotating portion 3616 of the first rotating end 361A of the first support member 36, and the third rotating portion 3715 and the fourth rotating portion 3716 of the second rotating end 371A of the second support member 37 can be designed according to the specific form, size and other model of the product.

[0325] Please refer to the following: Figures 37 to 39 , Figure 38 yes Figure 33 The diagram shown is an assembly schematic of a portion of the button assembly 30 in some embodiments. Figure 39 yes Figure 32 The diagram shows a partial cross-sectional view of the button assembly 30 along section HH in some other embodiments. Exemplary, Figure 38 The main illustration shows the assembly structure between the keycap 31, the first magnetic component 33, the first support component 36, and the second support component 37.

[0326] In this embodiment, the first movable end 362A of the first support member 36 is movably connected to the keycap 31. Exemplarily, the first body portion 3625 of the first movable end 362A can be located between the first guide rail block 3191 and the second guide rail block 3192 of the keycap 31. The first movable part 3626 of the first movable end 362A can be located within the first guide groove 3195 of the first guide rail block 3191, and can slide and rotate within the first guide groove 3195. The second movable part 3627 of the first movable end 362A can be located within the second guide groove 3196 of the second guide rail block 3192, and can slide and rotate within the second guide groove 3196. It is understood that the first movable end 362A is slidably connected to the keycap 31 and can rotate relative to it; that is, the first movable end 362A can slide and rotate relative to the keycap 31.

[0327] Understandably, when the first movable end 362A of the first support member 36 slides relative to the keycap 31 along the negative Y-axis, the inner wall of the first guide groove 3195 of the first guide block 3191 can be used to abut against the first movable part 3626 of the first movable end 362A, and the inner wall of the second guide groove 3196 of the second guide block 3192 can be used to abut against the second movable part 3627 of the first movable end 362A. Through the mutual cooperation between the inner wall of the first guide groove 3195 of the first guide block 3191 and the first movable part 3626, and the mutual cooperation between the inner wall of the second guide groove 3196 of the second guide block 3192 and the second movable part 3627, the sliding and rotation of the first movable end 362A relative to the keycap 31 can be restricted.

[0328] In this embodiment, the second movable end 372A of the second support member 37 is movably connected to the keycap 31. Exemplarily, the second body portion 3725 of the second movable end 372A can be located between the third guide rail block 3193 and the fourth guide rail block 3194 of the keycap 31. The third movable portion 3726 of the second movable end 372A can be located within the third guide groove 3197 of the third guide rail block 3193, and can slide and rotate within the third guide groove 3197. The fourth movable portion 3727 of the second movable end 372A can be located within the fourth guide groove 3198 of the fourth guide rail block 3194, and can slide and rotate within the fourth guide groove 3198. It is understood that the second movable end 372A is slidably connected to the keycap 31 and can rotate relative to it; that is, the second movable end 372A can slide and rotate relative to the keycap 31.

[0329] Understandably, when the second movable end 372A of the second support member 37 slides relative to the keycap 31 along the positive Y-axis, the inner wall of the third guide groove 3197 of the third guide block 3193 can be used to abut against the third movable part 3726 of the second movable end 372A, and the inner wall of the fourth guide groove 3198 of the fourth guide block 3194 can be used to abut against the fourth movable part 3727 of the second movable end 372A. Through the mutual cooperation between the inner wall of the third guide groove 3197 of the third guide block 3193 and the third movable part 3726, and the mutual cooperation between the inner wall of the fourth guide groove 3198 of the fourth guide block 3194 and the fourth movable part 3727, the sliding and rotation of the second movable end 372A relative to the keycap 31 can be restricted.

[0330] In this embodiment, the first rotating end 361A of the first support member 36 is movably connected to the second rotating end 371A of the second support member 37. For example, the first rotating portion 3615 of the first rotating end 361A can abut against the third rotating portion 3715 of the second rotating end 371A. For instance, the first sub-rotating portion 3615a of the first rotating portion 3615 can abut against the first sub-rotating portion 3715a of the third rotating portion 3715, and the second sub-rotating portion 3615b of the first rotating portion 3615 can abut against the second sub-rotating portion 3715b of the third rotating portion 3715. For example, the second rotating portion 3616 of the first rotating end 361A can abut against the fourth rotating portion 3716 of the second rotating end 371A. For example, the third sub-rotating part 3616a of the second rotating part 3616 can abut against the third sub-rotating part 3716a of the fourth rotating part 3716, and the second sub-rotating part 3615b of the second rotating part 3616 can abut against the fourth sub-rotating part 3716b of the fourth rotating part 3716.

[0331] It is understandable that, due to the height difference between the first sub-rotating portion 3615a and the second sub-rotating portion 3615b of the first rotating portion 3615 of the first support member 36, and the height difference between the first sub-rotating portion 3715a and the second sub-rotating portion 3715b of the third rotating portion 3715 of the second support member 37, when the first sub-rotating portion 3615a of the first rotating portion 3615 and the first sub-rotating portion 3715a of the third rotating portion 3715 abut, the second sub-rotating portions 3615b of the first rotating portion 3615 and the second sub-rotating portion 3715b of the third rotating portion 3715 can abut in the X-axis direction, thereby limiting each other and preventing the first rotating portion 3615 of the first support member 36 and the third rotating portion 3715 of the second support member 37 from separating in the X-axis direction. Similarly, since there is a height difference between the third sub-rotating part 3616a and the fourth sub-rotating part 3616b of the second rotating part 3616 of the first support member 36, and between the third sub-rotating part 3716a and the fourth sub-rotating part 3716b of the fourth rotating part 3716 of the second support member 37, it is beneficial to prevent the second rotating part 3616 of the first support member 36 and the fourth rotating part 3716 of the second support member 37 from separating in the X-axis direction.

[0332] In this embodiment, the first stop 3173 is located on one side of the first body portion 3625 of the first movable end 362A of the first support member 36. The first stop 3173 can be used to abut against the first body portion 3625 of the first movable end 362A when the first movable end 362A of the first support member 36 moves in the positive Y-axis direction. It can be understood that the first stop 3173 can stop the first support member 36 to prevent the first movable end 362A of the first support member 36 from moving out of the first guide groove 3195 of the first guide block 3191 and the second guide groove 3196 of the second guide block 3192. For example, when the button assembly 30 is in the third state, the first body portion 3625 of the first movable end 362A of the first support member 36 can abut against the first stop 3173, so that the first stop 3173 can prevent the first movable end 362A of the first support member 36 from moving out of the first guide groove 3195 of the first guide block 3191 and the second guide groove 3196 of the second guide block 3192.

[0333] In this embodiment, the second stop 3174 is located on one side of the second body portion 3725 of the second movable end 372A of the second support member 37. The second stop 3174 can be used to abut against the second body portion 3725 of the second movable end 372A when the second movable end 372A of the second support member 37 moves in the negative Y-axis direction. It can be understood that the second stop 3174 can stop the second support member 37 to prevent the second movable end 372A of the second support member 37 from moving out of the third guide groove 3197 of the third guide block 3193 and the fourth guide groove 3198 of the fourth guide block 3194. For example, when the button assembly 30 is in the third state, the second body portion 3725 of the second movable end 372A of the second support member 37 can abut against the second stop 3174, thereby preventing the second movable end 372A of the second support member 37 from moving out of the third guide groove 3197 of the third guide block 3193 and the fourth guide groove 3198 of the fourth guide block 3194.

[0334] Please refer to the following: Figure 39 and Figure 40 , Figure 40 yes Figure 33 The diagram shows a partial structure of the button assembly 30 in some embodiments from another angle. Exemplary, Figure 40 The assembly structure of the base plate 32, the second magnetic component 34, the first support component 36, and the second support component 37 is mainly shown.

[0335] In this embodiment, at least a portion of the first rotating end 361A of the first support member 36 may be located between the first fixed seat 3281 and the second fixed seat 3282. The first fixed seat 3281 and the second fixed seat 3282 may be used to limit the displacement of the first rotating end 361A in the X-axis direction.

[0336] In this embodiment, the first rotating end 361A of the first support member 36 is rotatably connected to the base plate 32. Exemplarily, the first rotating end 361A can be rotatably connected to the first fixed seat 3281 and the second fixed seat 3282 of the base plate 32. For example, the first rotating shaft portion 3617 of the first rotating end 361A can pass through the first rotating shaft groove 3285 of the first fixed seat 3281. The first rotating shaft portion 3617 can rotate within the first rotating shaft groove 3285. The second rotating shaft portion 3618 of the first rotating end 361A can pass through the second rotating shaft groove 3286 of the second fixed seat 3282. The second rotating shaft portion 3618 can rotate within the second rotating shaft groove 3286. In other embodiments, the structural form of the first rotating shaft portion 3617 of the first rotating end 361A and the structural form of the first rotating shaft groove 3285 of the first fixed base 3281 can be interchanged. That is, the first rotating end 361A can be provided with a rotating shaft groove structure or a rotating shaft hole structure, and the first fixed base 3281 can be provided with a rotating shaft or a protrusion structure. Similarly, the structural form of the second rotating shaft portion 3618 of the first rotating end 361A and the structural form of the second rotating shaft groove 3286 of the second fixed base 3282 can also be interchanged.

[0337] It is understood that in this embodiment, since the first fixing seat 3281 and the second fixing seat 3282 are fixed to the reinforcing plate 322, the first support member 36 can be rotatably connected to the electrical connection plate 321 through the first fixing seat 3281 and the second fixing seat 3282. In other embodiments, when the button assembly 30 does not include the first fixing seat 3281 and the second fixing seat 3282, or when the first fixing seat 3281 and the second fixing seat 3282 are integrally formed with the electrical connection plate 321, the first support member 36 is directly rotatably connected to the electrical connection plate 321.

[0338] In this embodiment, at least a portion of the second rotating end 371A of the second support member 37 may be located between the third fixing seat 3283 and the fourth fixing seat 3284. The third fixing seat 3283 and the fourth fixing seat 3284 may be used to limit the displacement of the second rotating end 371A in the X-axis direction.

[0339] In this embodiment, the second rotating end 371A of the second support member 37 is rotatably connected to the base plate 32. Exemplarily, the second rotating end 371A can be rotatably connected to the third fixed seat 3283 and the fourth fixed seat 3284 of the base plate 32. For example, the third rotating shaft portion 3717 of the second rotating end 371A can pass through the third rotating shaft groove 3287 of the third fixed seat 3283. The third rotating shaft portion 3717 can rotate within the third rotating shaft groove 3287. The fourth rotating shaft portion 3718 of the second rotating end 371A can pass through the fourth rotating shaft groove 3288 of the fourth fixed seat 3284. The fourth rotating shaft portion 3718 can rotate within the fourth rotating shaft groove 3288. In other embodiments, the structural form of the third rotating shaft portion 3717 of the second rotating end 371A and the structural form of the third rotating shaft groove 3287 of the third fixed seat 3283 can be interchanged; that is, the second rotating end 371A can be provided with a rotating shaft groove structure or a rotating shaft hole structure. The third fixing seat 3283 may be provided with a rotating shaft protrusion structure. Similarly, the structural form of the fourth rotating shaft portion 3718 of the second rotating end 371A and the structural form of the fourth rotating shaft groove 3288 of the fourth fixing seat 3284 may also be interchanged.

[0340] It is understood that in this embodiment, since the third fixing seat 3283 and the fourth fixing seat 3284 are fixed to the reinforcing plate 322, the second support member 37 can be rotatably connected to the electrical connection plate 321 through the third fixing seat 3283 and the fourth fixing seat 3284. In other embodiments, when the button assembly 30 does not include the third fixing seat 3283 and the fourth fixing seat 3284, or when the third fixing seat 3283 and the fourth fixing seat 3284 are integrally formed with the electrical connection plate 321, the second support member 37 is directly rotatably connected to the electrical connection plate 321.

[0341] In this embodiment, the first abutting portion 3619 of the first support member 36 can be located between the first fixed seat 3281 and the fourth fixed seat 3284. The first abutting portion 3619 can rotate relative to the first fixed seat 3281 and the fourth fixed seat 3284 around the first rotating shaft portion 3617. It is understood that during the rotation of the first abutting portion 3619 relative to the first fixed seat 3281 and the fourth fixed seat 3284, the first fixed seat 3281 and the fourth fixed seat 3284 can abut against the first abutting portion 3619 to restrict the first rotating portion 3615 from continuing to rotate relative to the base plate 32. For example, when the button assembly 30 is in the first state, the first abutting portion 3619 of the first support member 36 can abut against the first fixed seat 3281 and the fourth fixed seat 3284. The first fixed seat 3281 and the fourth fixed seat 3284 can restrict the rotation of the first support member 36 relative to the base plate 32.

[0342] For example, the second abutting portion 3719 of the second support member 37 can be located between the second fixed seat 3282 and the third fixed seat 3283, and the second abutting portion 3719 can rotate relative to the second fixed seat 3282 and the third fixed seat 3283 about the second rotating shaft portion 3618. It is understood that during the rotation of the second abutting portion 3719 relative to the second fixed seat 3282 and the third fixed seat 3283, the second fixed seat 3282 and the third fixed seat 3283 can abut against the second abutting portion 3719 to limit the second rotating portion 3616 from continuing to rotate relative to the base plate 32. For example, when the button assembly 30 is in the first state, the second abutting portion 3719 of the second support member 37 can abut against the second fixed seat 3282 and the third fixed seat 3283. The second fixed seat 3282 and the third fixed seat 3283 can limit the rotation of the second support member 37 relative to the base plate 32.

[0343] Please refer to the following: Figures 38 to 40 In this embodiment, the arrangement direction of the first support member 36 and the second support member 37 can be perpendicular to the Z-axis direction. For example, the first support member 36 and the second support member 37 can be arranged along the Y-axis direction. The first support member 36 and the second support member 37 are arranged at an angle.

[0344] For example, the first clearance hole 3601 of the first support member 36 connects to the second clearance hole 3701 of the second support member 37. The first clearance hole 3601 and the second clearance hole 3701 enclose a clearance space 301. For example, projecting along the first direction (i.e., along the Z-axis direction), on a plane perpendicular to the first direction (i.e., the XY plane), the projection of the clearance space 301 can cover the projections of the first magnetic member 33, the second magnetic member 34, and the elastic member 35. It is understood that the clearance space 301 can be used to avoid interference between the first magnetic member 33, the second magnetic member 34, and the elastic member 35 and the first support member 36 and the second support member 37.

[0345] Please see Figure 41 , Figure 41 yes Figure 32 The schematic diagram shown is of the first state of the partial cross-sectional structure of the button assembly 30 cut along HH in some embodiments.

[0346] In this embodiment, when the key assembly 30 is in the first state, the first support member 36 and the second support member 37 support the keycap 31. Exemplarily, the angle between the first support member 36 and the second support member 37 is a first angle. The first angle can be in the range of 120° to 140°. For example, the first angle can be 120°, 125°, or 140°, etc. At this time, the first support member 36 and the second support member 37 are approximately in a "scissor" shape.

[0347] Understandably, when the key assembly 30 is in the first state, the first movable end 362A of the first support member 36 can abut against the keycap 31, and the second movable end 372A of the second support member 37 can abut against the keycap 31, thereby restricting the second support member 37 from continuing to slide and rotate relative to the keycap 31 when the key assembly 30 is in the first state.

[0348] For example, the first magnetic element 33 and the second magnetic element 34 are spaced apart in the Z-axis direction, and the second magnetic element 34 is positioned opposite to the first magnetic element 33 in the first space 331. In this case, the first magnetic element 33 and the second magnetic element 34 repel each other in the Z-axis direction. That is, a magnetic repulsion force can be generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis direction. Due to the magnetic repulsion force and its own weight, the second magnetic element 34 compresses the elastic element 35 along the first direction, causing the elastic element 35 to be in a first compressed state. The elastic element 35 exerts an elastic force on the second magnetic element 34 along the second direction. In this case, the length of the elastic element 35 in the Z-axis direction is H1.

[0349] For example, in the Z-axis direction, the trigger portion 353 of the elastic member 35 is spaced apart from the electrical connection plate 321 of the base plate 32. At this time, the trigger portion 353 of the elastic member 35 does not trigger the base plate 32, and the base plate 32 does not generate an electrical signal.

[0350] Please see Figure 42 , Figure 42 yes Figure 32 The schematic diagram shown is of the second state of the partial cross-sectional structure of the button assembly 30 cut along HH in some embodiments.

[0351] In this embodiment, when the key assembly 30 is in the second state, the first support member 36 and the second support member 37 support the keycap 31. For example, the angle between the first support member 36 and the second support member 37 is a second angle. The second angle is greater than the first angle. The second angle can be in the range of 140° to 160°. For example, the second angle can be 145°, 150°, or 160°, etc. At this time, the first support member 36 and the second support member 37 are approximately in a "scissor" shape.

[0352] It is understandable that when the key assembly 30 is in the second state, the first movable end 362A of the first support member 36 can abut against the keycap 31, and the second movable end 372A of the second support member 37 can abut against the keycap 31, thereby restricting the second support member 37 from continuing to slide and rotate relative to the keycap 31 when the key assembly 30 is in the second state.

[0353] For example, at least a portion of the second magnetic element 34 is located within the first space 331. In this case, the repulsive force between the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction is equal to or close to zero.

[0354] For example, the keycap 31 can abut against the second magnetic element 34. The keycap 31 exerts a force on the second magnetic element 34 in a first direction, so that the second magnetic element 34 can compress the elastic element 35 in the first direction, causing the elastic element 35 to be in a second compressed state. The elastic element 35 exerts an elastic force on the second magnetic element 34 in a second direction. At this time, the sidewall 352 of the elastic element 35 deforms. The length of the elastic element 35 in the Z-axis direction is H2, and H2 ≤ H1. For example, H2 < H1, that is, the length of the elastic element 35 in the second compressed state is less than the length in the first compressed state.

[0355] For example, in the Z-axis direction, the trigger portion 353 of the elastic member 35 is spaced apart from the electrical connection plate 321 of the base plate 32, and the distance between the trigger portion 353 and the base plate 32 is less than the distance between the trigger portion 353 and the base plate 32 of the button assembly 30 in the first state. At this time, the trigger portion 353 of the elastic member 35 may still not trigger the base plate 32, and the base plate 32 does not generate an electrical signal.

[0356] Please refer to the following: Figure 41 and Figure 42 When the user presses the button component 30 in the first direction, the button component 30 can switch from the first state to the second state. During the transition of the key assembly 30 from the first state to the second state, the keycap 31 exerts a force along the first direction on the first support member 36 and the second support member 37, causing the first rotating end 361A of the first support member 36 to rotate relative to the first fixed base 3281 and the second fixed base 3282, and the first movable end 362A to slide relative to the keycap 31 (for example, the first movable end 362A can slide relative to the base plate 32 along the positive Y-axis) and rotate. At the same time, the second rotating end 371A of the second support member 37 rotates relative to the third fixed base 3283 and the fourth fixed base 3284, and the second movable end 372A can slide relative to the keycap 31 (for example, the second movable end 372A can slide relative to the base plate 32 along the negative Y-axis) and rotate. As a result, the first movable end 362A and the second movable end 372A gradually approach the base plate 32 along the first direction, that is, the height of the first support member 36 and the second support member 37 in the Z-axis direction decreases, and thus the keycap 31 can gradually approach the base plate 32 along the first direction. During this process, the first movable end 362A of the first support member 36 and the second movable end 372A of the second support member 37 move away from each other, the first support member 36 and the second support member 37 open up, and the included angle between the first support member 36 and the second support member 37 gradually increases.

[0357] During this process, there is always a magnetic repulsion force between the first magnetic component 33 and the second magnetic component 34 along the Z-axis, and the magnetic repulsion force between the first magnetic component 33 and the second magnetic component 34 first increases and then decreases. The user needs to overcome the magnetic repulsion force between the first magnetic component 33 and the second magnetic component 34 to achieve a pressing sensation and a tactile feedback.

[0358] Furthermore, during this process, the clearance space 301 can be used to avoid the first magnetic element 33, the second magnetic element 34, and the elastic element 35, thereby preventing interference between the first magnetic element 33, the second magnetic element 34, and the elastic element 35 and the first support element 36 and the second support element 37. It is understood that in this embodiment, by arranging the first support element 36 and the second support element 37 along the Y-axis, the clearance space 301 jointly enclosed by the first support element 36 and the second support element 37 is relatively large. That is, the first support element 36 and the second support element 37 can provide a larger clearance space 301 for the first magnetic element 33. Therefore, the first magnetic element 33 can be configured to include multiple magnetic parts 330 spaced apart. For example, the first magnetic element 33 may include a first magnetic part 330a and a second magnetic part 330b spaced apart. Thus, during the pressing of the button assembly 30, the magnetic repulsion force generated between the first magnetic element 33 and the second magnetic element 34 along the Z-axis first increases and then decreases. The stroke during the increase of the magnetic repulsion force is shorter, while the stroke during the decrease is longer, thereby increasing the B-C segment of the force stroke curve (see [reference]). Figure 15 The travel distance creates a greater sense of drop, which helps to improve the feel of pressing.

[0359] Please see Figure 43 , Figure 43 yes Figure 32 The schematic diagram shown is of the third state of the partial cross-sectional structure of the button assembly 30 cut along HH in some embodiments.

[0360] In this embodiment, when the key assembly 30 is in the third state, the first support member 36 and the second support member 37 support the keycap 31. For example, the angle between the first support member 36 and the second support member 37 is the third angle. The third angle is greater than the second angle. The third angle can be in the range of 160° to 180°. For example, the first angle can be 165°, 170°, 175°, or 180°, etc. When the second angle is 180°, the first support member 36 and the second support member 37 can be in a straight line. At this time, the first abutment portion 3619 (see [reference])... Figure 39 The second abutment part 3719 can be installed separately from the base plate 32. (See also: [link to relevant documentation]) Figure 40 It can be set separately from the base plate 32.

[0361] It is understandable that when the key assembly 30 is in the third state, the first movable end 362A of the first support member 36 can abut against the keycap 31, and the second movable end 372A of the second support member 37 can abut against the keycap 31, thereby restricting the second support member 37 from continuing to slide and rotate relative to the keycap 31 when the key assembly 30 is in the third state.

[0362] For example, at least a portion of the second magnetic element 34 is located within the first space 331. In this case, the repulsive force between the first magnetic element 33 and the second magnetic element 34 in the Z-axis direction is equal to or close to zero.

[0363] For example, the keycap 31 can abut against the second magnetic element 34. The keycap 31 exerts a force on the second magnetic element 34 in a first direction, so that the second magnetic element 34 can compress the elastic element 35 in the first direction, causing the elastic element 35 to be in a second compressed state. At this time, the sidewall 352 of the elastic element 35 deforms, and the degree of deformation of the sidewall 352 of the elastic element 35 is greater than the degree of deformation of the sidewall 352 of the elastic element 35 when the key assembly 30 is in the second state. The length of the elastic element 35 in the first direction is H3, and H3 < H2. That is, the length of the elastic element 35 in the third compressed state is less than the length in the second compressed state.

[0364] For example, in the Z-axis direction, the trigger portion 353 of the elastic member 35 can trigger the electrical connection plate 321 of the base plate 32. For example, the trigger portion 353 of the elastic member 35 can contact the electrical connection plate 321 of the base plate 32 to generate an electrical signal in the electrical connection plate 321.

[0365] Please refer to the following: Figure 42 and Figure 43 The user continues to press the button assembly 30 along the first direction, allowing the button assembly 30 to transition from the second state to the third state. During this transition, the keycap 31 continues to exert a force along the first direction on the first support member 36 and the second support member 37, causing the height of the first support member 36 and the second support member 37 in the Z-axis direction to continue decreasing. This allows the keycap 31 to gradually move closer to the base plate 32 along the first direction. During this process, the first movable end 362A of the first support member 36 and the second movable end 372A of the second support member 37 move away from each other, the first support member 36 and the second support member 37 open up, and the angle between the first support member 36 and the second support member 37 gradually increases.

[0366] During this process, the second magnetic element 34 continuously compresses the elastic element 35 along the first direction, causing the elastic force of the elastic element 35 on the second magnetic element 34 in the second direction to continuously increase. The user needs to continuously overcome the elastic force of the elastic element 35 to achieve a cushioning sensation. It is understood that in this embodiment, the pressing sensation and tactile feedback are achieved through the cooperation of the first magnetic element 33 and the second magnetic element 34, and the cushioning sensation is achieved through the cooperation of the second magnetic element 34 and the elastic element 35, thereby improving the user's tactile experience when pressing the button assembly 30.

[0367] In addition, during this process, the clearance space 301 can be used to avoid the first magnetic element 33, the second magnetic element 34 and the elastic element 35, thereby preventing the first magnetic element 33, the second magnetic element 34 and the elastic element 35 from interfering with the first support element 36 and the second support element 37.

[0368] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0369] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
