Description

Technical Field

[0001] This application relates to the field of keyboard technology, and more particularly to an elastic element, a keyboard, an electronic device, and a keyboard cover. Background Technology

[0002] As laptops become increasingly thinner and thinner, users are more prone to finger fatigue when pressing keys. The tactile feel of the keys has always been a key factor in keyboard design, especially for office workers who type for long periods and heavy gamers, directly impacting user experience, operational comfort, typing speed and accuracy, and overall user satisfaction. In summary, the tactile feel of the keys is an important factor that cannot be ignored in keyboard design, especially in thin electronic devices where improvements in the tactile feel are urgently needed. Summary of the Invention

[0003] The purpose of this application is to provide an elastic element, a keyboard, an electronic device, and a keyboard cover.

[0004] In a first aspect, embodiments of this application provide an elastic element, including a first part, a second part, a third part, and a triggering part, wherein the second part is deformable;

[0005] The second part is connected between the first part and the third part. The first part, the second part and the third part form a cover space. The opening of the cover space is located in the third part. The trigger part is connected to the first part and is located in the cover space.

[0006] The first part includes a main body and a molding part. The main body is connected to the second part, and the molding part is connected to the trigger part. The molding part is located on the side of the trigger part away from the cover space and forms a buffer space with the trigger part. In a first direction, the projection of the molding part at least partially covers the projection of the buffer space. The first direction is the arrangement direction of the first part and the second part.

[0007] In this example, the second part serves as the sidewall of the elastic element's enclosure space. The second part is prone to deformation and can act as the primary deformation structure of the elastic element; when the elastic element is subjected to force, the deformation of the second part can be relatively large. It is understood that the first and third parts can also deform, but their deformation can be less than that of the second part.

[0008] Because the first part has a buffer space containing air, this buffer space effectively weakens the structure of the first part, making the sidewalls of the first part forming the buffer space more prone to deformation. Therefore, when the elastic element is subjected to force, both the second and first parts can deform; moreover, the second part will deform first as the primary deformation structure, and the third part will deform as the deformation structure after the second part has undergone a certain amount of deformation. This gives the elastic element multi-stage deformation capability, resulting in a smoother change in elastic force during deformation and reducing abrupt changes in the magnitude of the elastic force.

[0009] Furthermore, in the keyboard, when a key is pressed, the deformation of the second part provides the first stage of elastic force, thus providing the user with a tactile feedback. The deformation of the first part (buffer space) also prevents a sudden increase in the elastic force of the elastic element when the trigger contacts the base plate. The deformation of the first part (buffer space) provides a second stage of elastic force, thus providing the user with a second stage of tactile feedback. Therefore, when the user uses the keyboard, the elastic element has a cushioning capability, and the user's fingers do not feel like they are hitting a hard plate. With increased keystrokes, the fingers are less prone to fatigue, making the keyboard easier to use.

[0010] In some implementations, the buffer space is a sealed cavity.

[0011] The buffer space can contain gas, and because the buffer space is enclosed, the sidewalls of the buffer space are equivalent to the structure that forms an airbag.

[0012] In this embodiment, when the elastic element is compressed, the buffer space is compressed and deformed, and the internal air is also compressed. The air also plays a role in providing elasticity, which helps the first part to have a suitable supporting force on the trigger part and makes the buffer space have a better buffering capacity.

[0013] In some embodiments, the first part has a connecting hole that connects the buffer space and the cover space; or, the connecting hole connects the buffer space and the space on the side of the molding part opposite to the buffer space.

[0014] For example, the connecting hole can be formed in the molding part. Since the molding part is located on the side of the trigger part away from the cover space, forming a connecting hole in the molding part can connect the buffer space with the space on the side away from the cover space, that is, connect the buffer space with the space on the top side of the molding part.

[0015] For example, the buffer space and the cover space are separated by a trigger part and a first part. Therefore, a connecting hole can be formed in the separation structure between the buffer space and the cover space, thereby connecting the two. At this time, when the buffer space deforms, the gas inside it can be discharged into the cover space.

[0016] In this embodiment, the first part is deformable, preventing the elastic force of the elastic element on the outside from suddenly increasing, thus providing a buffering effect. For the user, the trigger part can feel the bottoming out, and the reaction force of the button on the finger does not suddenly increase, but increases gradually. The elastic element can buffer when the user presses the button, while still providing a tactile feedback, thus ensuring a good tactile experience and reducing user fatigue.

[0017] In some embodiments, the main body has a recessed groove located on the side of the main body away from the third part;

[0018] The settling tank is arranged around the buffer space; or, the settling tank and the buffer space are arranged along a first direction, and the projection of the settling tank in the first direction covers the projection of the buffer space in the first direction.

[0019] For example, the settling tank can be formed by a recess in the surface of the first portion facing away from the third portion. The diameter of the settling tank can be larger than the diameter of the buffer space. For example, the settling tank can be connected to the buffer space through a connecting hole.

[0020] For example, the settling tank and the buffer space overlap in a first direction, such that the settling tank surrounds the periphery of the buffer space. A molding portion can be used to form the bottom wall of the settling tank.

[0021] In this embodiment, by setting a sink groove, less material is used around the buffer space, thereby making the first part more flexible. When the elastic element deforms and the trigger part and the third part are flush with the surface of the first part, the first part and / or the trigger part are easier to deform, thus having a better buffering effect. This is beneficial for setting a suitable buffering capacity according to the user's feel requirements.

[0022] In some embodiments, the surface of the main body that is away from the third part is smoothly connected to the surface of the molding part that is away from the third part.

[0023] In this embodiment, the surface of the main body facing away from the third part and the surface of the molding part facing away from the third part can serve as the end face of the first part, thereby increasing the contact area between the first end and other components (keycaps) and making the connection more stable; furthermore, the elastic element provides more stable support for the keycaps. Additionally, the structure of the elastic element can be simplified, its manufacturing process can be made simpler, and the cost can be reduced.

[0024] In some embodiments, along the first direction, the diameter of the projected buffer space is R1, and the diameter of the projected first portion is R2.

[0025] Where, (R²*0.25) <R1<(R2*0.5)。

[0026] The height of the buffer space can be less than its diameter. The height of the buffer space b can be in the first direction (Z direction), and the diameter of the buffer space can be perpendicular to the first direction. The diameter of the first part can also be perpendicular to the first direction.

[0027] In this embodiment, by reasonably setting the size relationship between the buffer space and the first part, the buffer space has a suitable volume, so that the first part can take into account both the buffer performance and the stopping sensation during deformation.

[0028] In some embodiments, the elastic element further includes a buffer portion, which is fixedly connected to the third part and located on the side of the third part away from the cover space, and the buffer portion is elastic.

[0029] In this embodiment, the buffer part, by contacting the support member, buffers the latter half of the keycap's movement toward the base plate, achieving a "soft landing" of the keycap and preventing it from stopping abruptly when it reaches the lowest point. This avoids a sudden increase in the reaction force of the keycap on the user, prevents the user from experiencing the feeling of pressing a hard plate, thereby improving the user's keyboard feel and reducing user fatigue during use.

[0030] In some embodiments, the buffer portion surrounds the third portion, and the thickness of the buffer portion is different from the thickness of the third portion.

[0031] The thickness of the buffer section can be less than the thickness of the third section.

[0032] In this embodiment, the buffer part has a shape that is approximately the same as the third part, making it easy to connect to the third part.

[0033] In some embodiments, the buffer portion is a plate-shaped structure, and the surface of the buffer portion facing away from the first portion is flush with the surface of the third portion facing away from the first portion.

[0034] At this time, the buffer part is far away from the first part and the position of the buffer part is low. Other parts only come into contact with the buffer part when they move close to the bottom of the elastic element. Therefore, the buffer part buffers the movement of the last part of the other parts.

[0035] Alternatively, the surface of the buffer portion facing away from the first portion and the surface of the third portion facing away from the first portion are spaced apart.

[0036] At this point, the buffer section is relatively close to the first part and is positioned higher, essentially suspended in mid-air. When other components move to the third part, which is close to the elastic element, they can contact the buffer section. After the other components contact the buffer section, it will first bend and deform, and then be compressed and deformed, thus providing appropriate cushioning for the support component.

[0037] In some embodiments, in the first direction, the cross-section of the buffer portion extends at least partially in a curved manner.

[0038] The cross-section of the buffer section can be a surface that is coplanar with the central axis of the buffer section.

[0039] For example, the buffer portion may include a first fixing portion, a deformable portion, and a second fixing portion. The first fixing portion, the deformable portion, and the second fixing portion are connected sequentially. The first fixing portion is fixed to the third portion. The deformable portion may be generally annular in shape, and its cross-section may extend in an arc.

[0040] In this embodiment, the deformable part is equivalent to a raised part. After being squeezed, the deformable part can first undergo bending deformation, which serves as a buffer.

[0041] In some embodiments, the thickness of the buffer portion gradually increases from one end to the other in a direction perpendicular to the first direction.

[0042] In this embodiment, when other components come into contact with the buffer part by rotating, it is beneficial to make the surface of the other components contact the top side surface of the buffer part synchronously, thereby synchronously squeezing all parts of the buffer part, so that all parts of the buffer part can deform and buffer synchronously, which is beneficial to make the buffer part buffering smoother.

[0043] In some embodiments, the buffer portion is a conical structure that extends along the periphery of the third portion in a direction away from the third portion and in a direction away from the first portion.

[0044] In this embodiment, the buffer part is located close to the first part and is positioned relatively high, essentially suspended in mid-air. When other components come into contact with the buffer part, it will first bend and deform, and then be compressed and deformed, thereby providing appropriate cushioning for the support member.

[0045] In some implementations, the elastic element is a one-piece molded structural component.

[0046] In this embodiment, the buffer portion can be molded simultaneously with other structures of the elastic element, making the manufacturing of the elastic element simpler. Furthermore, no new components need to be added during keyboard assembly, simplifying the assembly process.

[0047] In some embodiments, the third part is an annular ring with an outer diameter of R1a and an inner diameter of R1b, wherein R1b > (0.8 * R1a).

[0048] The first part is cylindrical, with an outer diameter of R2. The trigger part is also cylindrical, with a diameter of R3, where R2 * (1 / 3) <R3<R2*(1 / 2);

[0049] The wall thickness of the second part is w, where 0.25 mm < w < 0.35 mm;

[0050] In the first direction, the distance between the surface of the third part facing away from the first part and the trigger part is L, and the height of the elastic member is H, where 0.3*H < L < 0.4*H.

[0051] In this embodiment, by defining the dimensions of the first part, the dimensional relationship between the first part and the trigger part, the dimensions of the second part, and the position of the trigger part in the elastic member, etc., the cover space of the elastic member has a relatively large volume, which is conducive to making the pressing loss value of the elastic member smaller, so that the keyboard keys can take into account the paragraph feel when pressing the keys and the resilience when the keys rebound.

[0052] In some embodiments, the included angle between the axis of the third part and the second part is A, where 140° < A < 160°; and / or, the second part and the first part are connected on the surface of the cover space, and the included angle between the surfaces of the second part and the first part located in the cover space is B, where 110° < A < 150°.

[0053] In this embodiment, by further defining the included angle between the axis of the third part and the second part, and the included angle between the surfaces of the second part and the first part located in the cover space, the second part has an appropriate inclination degree, so that the second part can be deformed under an appropriate force, thereby having a good paragraph feel, and at the same time taking into account that the cover space has a relatively large volume, which is conducive to improving the overall use feel of the elastic member.

[0054] In some embodiments, the elastic member satisfies: 4 mm < R1b < 4.2 mm; 0.75 mm < L < 0.85 mm.

[0055] In this embodiment, by defining the inner diameter dimension of the third part and the bottoming distance of the trigger part, it is conducive to making the elastic member have a suitable size and a suitable use feel.

[0056] In a second aspect, an embodiment of the present application provides a keyboard, including a bottom plate and a plurality of keys. The plurality of keys are fixed on the same side of the bottom plate; the bottom plate has a plurality of key switches; the keys include keycaps, support members, and an elastic member provided in any one of the embodiments of the first aspect. The keycaps are spaced apart and opposite to the bottom plate. The support members connect the keycaps and the bottom plate, and the support members can be deformed; the elastic member is located inside the support members. The first part of the elastic member is fixedly connected to the keycap, and the third part of the elastic member is fixedly connected to the bottom plate; the elastic member is arranged corresponding to the key switch. When the keycap is pressed, the elastic member triggers the key switch.

[0057] In this embodiment, when a keycap is pressed, the second part of the elastic element deforms, causing the keycap to move towards the base plate. Simultaneously, the trigger portion moves towards the base plate. When the trigger portion contacts the base plate, due to the buffer space in the first part, the first part (buffer space) can continue to deform until the keycap stops moving. Specifically, the deformation of the second part when the key is pressed provides a first stage of elastic force, thus providing the user with a first-stage tactile feedback. The deformation of the first part (buffer space) also prevents a sudden increase in the elastic force of the elastic element when the trigger portion contacts the base plate; the deformation of the first part (buffer space) provides a second stage of elastic force, thus providing the user with a second stage of tactile feedback. Therefore, when the user uses the keyboard, the elastic element has a buffering capacity, preventing the user's fingers from feeling like they are hitting a hard plate. With increasing keystrokes, the fingers are less prone to fatigue, making the keyboard easier to use.

[0058] The keycaps are connected to the base plate via support components and elastic elements. Each keycap has a supporting structure, ensuring reliable fixation within the keyboard with minimal wobble and good stability. This provides a comfortable typing experience, reduces user fatigue, and enhances the overall user experience.

[0059] In some embodiments, the first part has a connecting hole, which is formed in the molding part; the keycap has a guide groove, which connects the outer space of the first part and the connecting hole; or, the first part is sealed to the keycap, and the keycap blocks the connecting hole.

[0060] In this embodiment, the guide channel can be connected to the buffer space through the connecting hole. When the elastic element deforms, the gas in the buffer space can flow out to the outside of the elastic element through the guide channel, or be drawn into the buffer space from the outside of the elastic element.

[0061] In some embodiments, the elastic element further includes a buffer portion, which is fixedly connected to the third part and located on the outside of the third part away from the cover space, and the buffer portion is flexible;

[0062] When the keycap is not pressed, the buffer part has a first gap with the keyboard;

[0063] When a keycap is pressed, the distance between the buffer and the keyboard is less than the first spacing, and the support abuts against the buffer.

[0064] In this embodiment, the buffer part, by contacting the support member, buffers the latter half of the keycap's movement toward the base plate, achieving a "soft landing" of the keycap and preventing it from stopping abruptly when it reaches the lowest point. This avoids a sudden increase in the reaction force of the keycap on the user, prevents the user from experiencing the feeling of pressing a hard plate, thereby improving the user's keyboard feel and reducing user fatigue during use.

[0065] In addition, since the buffer part is a ring-shaped component, all parts of the ring-shaped surface of the buffer part can contact the support component, thereby providing uniform buffering to the support component and improving the buffering capacity of the buffer part.

[0066] In some embodiments, the support includes a first support frame and a second support frame, the first support frame and the second support frame are hinged at the middle, a keycap is rotatably connected to a first end of the first support frame, a base plate is movably connected to a second end of the first support frame, a keycap is movably connected to a first end of the second support frame, and a base plate is movably connected to a second end of the second support frame.

[0067] The first support frame has a central hole, and the elastic element is fitted into the central hole; when the keycap is pressed, the distance between the buffer part and the keyboard is less than the first spacing, and the first support frame abuts against the buffer part.

[0068] In this embodiment, when the keycap is pressed, the first support frame and the second support frame rotate relative to each other, so that the first end of the first support frame moves closer to the second end of the second support frame, and the first end of the second support frame moves closer to the second end of the first support frame, so that the keycap can move closer to the base plate and the keycap can be stably supported during the movement.

[0069] In some embodiments, the thickness of the buffer portion gradually increases from one end to the other in a direction perpendicular to the first direction; the thickness of the buffer portion on the side near the first end of the first support frame is higher than the thickness of the buffer portion on the side near the second end of the first support frame.

[0070] In this embodiment, the thinner side of the buffer portion is located near the second end of the first support frame, while the thicker side is located near the first end of the first support frame. In this configuration, the first end of the first support frame can rotate relative to the second end, and the top surface of the buffer portion is inclined, making the shape of the buffer portion more compatible with the movement of the first support frame. That is, when other components (the first support frame) come into contact with the buffer portion through rotation, it facilitates synchronous contact between the surface of the first support frame and the top surface of the buffer portion, thereby synchronously compressing all parts of the buffer portion and causing synchronous deformation and buffering, resulting in smoother buffering.

[0071] Thirdly, embodiments of this application provide an electronic device including a keyboard as provided in any of the embodiments of the second aspect.

[0072] In this embodiment, the electronic device can reduce user fatigue during use, provide a good user experience, achieve a thin and light design, and has a low cost.

[0073] Fourthly, embodiments of this application provide a keyboard cover, including a protective cover and a keyboard as provided in any embodiment of the second aspect, wherein the keyboard is mounted on the protective cover.

[0074] In this embodiment, the keyboard cover reduces user fatigue during use, provides a good user experience, achieves a thin and light design, and has a low cost. Attached Figure Description

[0106] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0107] In some embodiments, the electronic device 1000 includes a housing 100, a keyboard 200, and a display screen 300. Both the keyboard 200 and the display screen 300 are mounted on the housing 100. For example, the electronic device 1000 may be a laptop computer.

[0108] The housing assembly 100 may include a top shell 1001 and a bottom shell 1002. The top shell 1001 and the bottom shell 1002 are rotatably connected, allowing the top shell 1001 to rotate relative to the bottom shell 1002, thereby enabling the top shell 1001 to open and close relative to the bottom shell 1002. The top shell 1001 and the bottom shell 1002 may have approximately the same shape to ensure a tighter fit when they are engaged.

[0109] For example, the top shell 1001 and the bottom shell 1002 can be rotatably connected by a pivot, or the top shell 1001 and the bottom shell 1002 can be rotatably connected by a hinge. For example, the maximum opening angle of the top shell 1001 relative to the bottom shell 1002 can be in the range of 90° to 360°, such as 150°, 180°, 270° or 360°, etc., and this embodiment does not strictly limit this.

[0110] The keyboard 200 can be fixedly installed on the bottom shell 1002. The keyboard 200 can have multiple keys 20, which can be spaced apart from each other. The keyboard 200 can be exposed relative to the bottom shell 1002 for easy operation.

[0111] The display screen 300 can be fixedly installed on the top shell 1001. The display screen 300 can occupy most of the area of ​​the top shell 1001, and the display screen 300 can protrude from the top shell 1001 to facilitate the display of images.

[0112] It is understandable that when the top shell 1001 and the bottom shell 1002 are fastened together, the display screen 300 and the keyboard 200 can be positioned relative to each other, and the display screen 300 and the keyboard 200 are housed by the housing device 100 to protect the keyboard 200 and the display screen 300.

[0113] In some embodiments, the electronic device 1000 may further include a circuit board assembly (not shown). The circuit board assembly may have a processor, memory, motherboard, etc., and the processor, memory, etc. may be disposed on the motherboard.

[0114] For example, both the display screen 300 and the keyboard 200 can be communicatively connected to the circuit board assembly. For instance, the display screen 300 and the keyboard 200 can be connected to corresponding interfaces of the circuit board assembly via cables. The user can operate the keyboard 200 to input signals to the circuit board assembly, and the circuit board assembly can calculate and output signals to the display screen 300, causing the display screen 300 to display corresponding content.

[0115] In some examples, the circuit board assembly may also have various interfaces such as a USB (Universal Serial Bus) interface, an audio interface, and a power interface. These various interfaces may be fixed to the motherboard and exposed relative to the housing assembly 100.

[0116] In some embodiments, the electronic device 1000 may further include a touch panel 400. The touch panel 400 may be mounted on the base housing 1002 and communicatively connected to the circuit board assembly. The touch panel 400 may also be operated by a user to input signals to the circuit board assembly, thereby causing the display screen 300 to display corresponding content.

[0117] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of another electronic device 1000 provided in this application.

[0118] In some embodiments, the electronic device 1000 may include a host 500 and a keyboard 200.

[0119] For example, the host device 500 can be a tablet device, such as a tablet computer or a mobile phone. The host device 500 may include a housing 100, a display screen 300, and a circuit board assembly. The housing 100 may have a generally rectangular, flat structure. The circuit board assembly may be fixed to the inside of the housing 100. The circuit board assembly may have a processor, memory, motherboard, etc., and the processor and memory may be located on the motherboard. The display screen 300 may be fixed to the housing 100 and exposed relative to the housing 100. The display screen 300 can communicate with the circuit board assembly and can be used for touch control and display.

[0120] For example, a user can touch the display screen 300 to cause the display screen 300 to input a signal to the circuit board assembly. After processing the signal, the circuit board assembly can output the corresponding signal to the display screen 300, and the display screen 300 will display the corresponding content.

[0121] The keyboard 200 can be a device independent of the host 500. The keyboard 200 can be connected to the host 500 as an external device. The keyboard 200 can communicate with the host 500 to input signals to the host 500, thereby controlling the host 500.

[0122] For example, the keyboard 200 can be connected to the host 500 wirelessly via Bluetooth or other means, or the keyboard 200 can be electrically connected to the host 500 via metal contacts and transmit signals through the metal contacts. This embodiment does not strictly limit the method of communication between the keyboard 200 and the host 500. In some embodiments, the keyboard 200 and the host 500 can be magnetically connected to each other to fix their relative positions.

[0123] In some other examples, when the host 500 is a desktop device, the keyboard 200 can be electrically connected to the electronic device 1000 via a data cable, in which case the keyboard 200 can serve as an input device for the electronic device 1000. It is understood that the host 500 and the display screen 300 can be configured independently, with the display screen 300 serving as an external device for the host 500, and the host 500 and the display screen 300 can be connected via a cable.

[0124] In other examples, when the host 500 is a laptop, the keyboard 200 can be electrically connected to the host 500 via a cable, or the keyboard 200 can be wirelessly connected to the host 500. It is understood that the laptop may have a built-in keyboard 200, and both an external keyboard 200 and the laptop's own keyboard 200 can be used as input devices to control the laptop.

[0125] Please see Figure 3 , Figure 3 This is a structural schematic diagram of another electronic device 1000 provided in this application.

[0126] In some embodiments, the electronic device 1000 may include a display screen 300 and a host 500.

[0127] For example, the host 500 may include a housing 100, a circuit board assembly, and a keyboard 200. The circuit board assembly may be fixed to the inside of the housing. The circuit board assembly may have a processor, memory, motherboard, etc., and the processor, memory, etc., may be disposed on the motherboard. The keyboard may be fixed to the housing and exposed relative to the housing.

[0128] For example, the display screen 300 and the host unit 500 can be detachably connected. The housing of the host unit 500 may have a first connecting portion 1003, and the display screen 300 may have a second connecting portion 3001. The first connecting portion 1003 and the second connecting portion 3001 can form a detachable connection structure. When the first connecting portion 1003 and the second connecting portion 3001 are connected, the display screen 300 and the host unit 500 can be used as a single device, and the display screen 300 can be fastened to the host unit 500 for carrying the electronic device 1000. When the first connecting portion 1003 and the second connecting portion 3001 are separated, the display screen 300 and the host unit 500 can be used as two separate devices, and the display screen 300 and the host unit 500 can be placed in different locations depending on the usage scenario.

[0129] For example, the display screen 300 can be communicatively connected to the host computer 500. For instance, when the display screen 300 and the host computer 500 are connected, they can be electrically connected simultaneously, enabling them to communicate via wired transmission. When the display screen 300 and the host computer 500 are disconnected, they can communicate wirelessly.

[0130] Please see Figure 4 , Figure 4 This is a structural schematic diagram of a keyboard cover 2000 provided in this application.

[0131] In some embodiments, the keyboard cover 2000 may include a protective cover 600 and a keyboard 200. The keyboard 200 is installed inside the protective cover 600, which can house the keyboard 200 to protect it and reduce the space occupied by the keyboard cover 2000.

[0132] For example, the protective cover 600 may have a first cover 6001, a second cover 6002, and a third cover 6003. The first cover 6001 and the second cover 6002 are fixedly connected by the third cover 6003. The first cover 6001 and the second cover 6002 can be unfolded and folded relative to each other, thereby placing the keyboard cover 2000 in an open state and a closed state. The first cover 6001 and the second cover 6002 can open and close between 0° and 360°. The second cover 6002 and the first cover 6001 can also form a fixed angle, such as 120°, 135°, 150°, etc. When the first cover 6001 and the second cover 6002 are in the unfolded state relative to each other, the third cover 6003 is used to support the second cover 6002.

[0133] The keyboard 200 can be fixed to the first housing 6001. The bottom of the keyboard 200 can be glued to the surface of the first housing 6001. In some other examples, the keyboard 200 can also be detachably connected to the protective cover 600.

[0134] The second assembly 6002 may have a mounting slot 6004 for placing an electronic device. The electronic device may be a tablet computer, mobile phone, or other tablet-like device. The second assembly 6002 can support the electronic device and create an angle between the electronic device and the keyboard 200 for easy use. The electronic device can communicate with the keyboard 200 via wired or wireless means to control the electronic device through the keyboard 200.

[0135] At this time, the protective cover 600 can be used to store electronic devices and keyboard 200 at the same time, so as to protect and store electronic devices and keyboard 200 simultaneously.

[0136] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a keyboard 200 provided in this application.

[0137] Figure 5 The keyboard 200 shown can be applied to Figure 1 Examples to Figure 3 In the electronic device 1000 shown in the embodiment, or applied to Figure 4 In the keyboard case shown in the embodiment, the keyboard 200 can also be a standalone device. The following description mainly uses the standalone keyboard 200 as an example, and the structure of the keyboard 200 applied to other electronic devices 1000 can be designed with reference to the standalone keyboard 200.

[0138] In some embodiments, the keyboard 200 may include a base plate 10, a plurality of keys 20, and a frame 30. The side of the base plate facing away from the keys is defined as the "bottom," and the side of the base plate facing the keys is defined as the "top." The direction perpendicular to the base plate 10 is defined as the height direction of the keyboard 200, and the height direction of the keys 20 may be parallel to the height direction of the keyboard 200. The height direction of the keyboard 200 is the Z-direction, the width direction is the X-direction, and the length direction is the Y-direction.

[0139] Multiple buttons 20 can be fixed to the same side of the base plate 10, which is used to support the multiple buttons 20. For example, the multiple buttons 20 can be fixed to the top side of the base plate 10.

[0140] The base plate 10 may have multiple push-button switches, and buttons 20 can be used to trigger the push-button switches to realize the control functions of the keyboard 200. The push-button switches can be configured corresponding to buttons 20; for example, multiple push-button switches can be configured one-to-one with multiple buttons 20. The multiple buttons 20 can be spaced apart to allow for independent operation of each button 20. In some other embodiments, one button 20 may also correspond to multiple push-button switches.

[0141] The button 20 can be roughly rectangular in shape, but in some other embodiments, it can also be circular. The size of the buttons 20 can vary. The number of buttons 20 can be greater than 60, for example, 61, 86, 101, 104, etc. The shape, size, and number of buttons 20 can be adapted to meet specific needs, and this embodiment does not impose strict limitations.

[0142] The frame 30 can be fixedly connected to the base plate 10. For example, the frame 30 can be roughly plate-shaped, and the frame 30 and multiple buttons 20 can be located on the same side of the base plate 10. The frame 30 has multiple clearance holes, and the buttons 20 are located within the clearance holes, which provide space for the buttons 20 to move. The number of clearance holes can be the same as the number of buttons 20, and the multiple clearance holes correspond one-to-one with the multiple buttons 20. In other examples, the frame 30 can be a cover structure, and the base plate 10 can be located inside the frame 30 to protect the base plate 10.

[0143] In some other embodiments, the keyboard 200 may not include the frame 30, or the frame 30 may be formed from the housing structure of the electronic device.

[0144] Please refer to the following: Figures 6 to 8 , Figure 6 yes Figure 5 The schematic diagram of part of the keyboard 200 shown is a structural diagram of some embodiments. Figure 7 yes Figure 6 A cross-sectional schematic diagram of a portion of the structure of the keyboard 200 shown. Figure 8 yes Figure 6 The diagram shows a partial structural breakdown of the keyboard 200 in some embodiments.

[0145] In some embodiments, the base plate 10 may include a support plate 101 and a thin-film circuit board 102. For example, the button 20 may be located on the side of the thin-film circuit board 102 opposite to the support plate 101, but is not strictly limited thereto.

[0146] The support plate 101 may be, but is not limited to, a rigid metal plate such as a steel plate, so as to provide support for the thin film circuit board 102 and the button 20.

[0147] A switch circuit can be provided on the thin film circuit board 102. The switch circuit has a push button switch 1021. When the button 20 is pressed, the push button switch 1021 of the thin film circuit board 102 can be changed from an open circuit state to an open circuit state to trigger the pressed button 20, thereby realizing the input function corresponding to the button 20.

[0148] In some other examples, the base plate 10 may also have a backlight. In this case, the keyboard 200 may have an illumination function, or each key 20 of the keyboard 200 may have an independent illumination function. The specific settings can be made according to actual needs, and this embodiment is not strictly limited.

[0149] In some embodiments, the key 20 may include a keycap 1, a support member 2, and an elastic member 3. The keycap 1 and the base plate 10 are spaced apart and disposed opposite to each other, and the support member 2 and the elastic member 3 are located between the keycap 1 and the base plate 10.

[0150] For example, a button 20 may have a spring element 3, and multiple spring elements 3 may be configured to correspond one-to-one with multiple button switches 1021.

[0151] In other examples, a single elastic element 3 of a button 20 can be associated with multiple push-button switches 1021, all of which can be used to trigger the button 20. Alternatively, a button 20 can have multiple elastic elements 3, each of which is associated with a push-button switch 1021. In this case, a single button 20 is effectively associated with multiple push-button switches 1021, all of which can be used to trigger the button 20. This makes it easier to trigger the button 20 when it is relatively long.

[0152] The keycap 1 can be roughly rectangular in shape. The keycap 1 can be relatively thin to minimize its impact on the height of the key 20. A flat plate can be formed in the center of the keycap 1, which can be used to securely connect the elastic element 3 and the support element 2.

[0153] The keycap 1 can be made of a high-strength, rigid material. For example, the keycap 1 can be made of rigid plastics such as PC (Polycarbonate); or, the keycap 1 can also be made of glass fiber. This embodiment does not strictly limit the material of the keycap 1. In this case, by choosing the material of the keycap 1, it is easy to form a high-strength structure.

[0154] The support member 2 can be installed between the keycap 1 and the base plate 10. The support member 2 can support the keycap 1 and the base plate 10. The support member 2 is deformable; when the keycap 1 is pressed, the support member 2 can deform, thereby bringing the keycap 1 and the base plate 10 closer together. The support member 2 can be connected to the edge of the keycap 1.

[0155] For example, the support member 2 may include a first support frame 21 and a second support frame 22. The first support frame 21 and the second support frame 22 are hinged at the middle. The first end of the first support frame 21 is rotatably connected to the keycap 1, and the second end of the first support frame 21 is movably connected to the base plate 10. The first end of the second support frame 22 is movably connected to the keycap 1, and the second end of the second support frame 22 is movably connected to the base plate 10. At this time, the first support frame 21 and the second support frame 22 form a "scissor-leg" structure, and the first support frame 21 and the second support frame 22 can rotate relative to each other. When the keycap 1 is pressed, the first support frame 21 and the second support frame 22 rotate relative to each other, so that the first end of the first support frame 21 moves closer to the second end of the second support frame 22, and the first end of the second support frame 22 moves closer to the second end of the first support frame 21, so that the keycap 1 can move closer to the base plate 10, and the keycap 1 can be stably supported during the movement.

[0156] The elastic element 3 can fix the keycap 1 to the base plate 10. The elastic element 3 is used to trigger the button switch 1021 when the keycap 1 is pressed; that is, the elastic element 3 can contact or press the button switch 1021 through deformation to trigger the button switch 1021, thereby changing the button switch 1021 of the membrane circuit board 102 from the open circuit state to the closed circuit state.

[0157] For example, the elastic element 3 can be located inside the support 2. The elastic element 3 can be fixedly connected to the center of the keycap 1 and fixedly connected to the base plate 10, and is correspondingly set with the key switch 1021.

[0158] Among them, the elastic element 3 can have the ability to deform. When the keycap 1 is pressed, the elastic element 3 can be deformed and compressed, the keycap 1 moves toward the base plate 10, and the elastic element 3 triggers the key switch 1021.

[0159] Among them, the elastic element 3 can be made of a flexible material, so that the elastic element 3 is easy to deform.

[0160] For example, the material of the elastic element 3 can be silicone, silicone rubber, or a flexible polymer material. For example, flexible polymer materials can include SBS (Styrene-Butadiene-Styrene block copolymers), SIS (Styrene-Isoprene-Styrene block copolymers), SEBS (Styrene-Butadiene-Styrene block copolymers), EPDM (Ethylene Propylene Diene Monomer), POE (Polyolefin elastomer), TPE (Thermoplastic Elastomer), TPV (Thermoplastic Vulcanizate), TPO (Thermoplastic Polyolefin), and TPU (Thermoplastic Polyurethane). These include thermoplastic polyurethane elastomers (TREEs), thermoplastic polyester elastomers (TREEs), and polyphenylene ether (PPEs). In this case, the elastic element 3 easily forms a deformable structure.

[0161] The elastic element 3 can be roughly shaped like a cover, forming a cover space 3a. In this case, the elastic element 3 is easy to deform under force and has sufficient deformation space.

[0162] For example, the elastic element 3 may include a first portion 31, a second portion 32, a third portion 33, and a trigger portion 34. The second portion 32 is connected between the first portion 31 and the third portion 33. The first portion 31, the second portion 32, and the third portion 33 form a cover space 3a. The opening of the cover space 3a is located in the third portion 33. The first portion 31 and the second portion 32 are arranged along a first direction. The trigger portion 34 is connected to the first portion 31 and is located in the cover space 3a. The first direction may be parallel to the Z-direction.

[0163] The second part 32 can be deformable. The second part 32 can be roughly in the shape of a hollow frustum. The second part 32 can surround the center of the first part 31.

[0164] The trigger part 34 is located in the housing space 3a and faces the opening of the housing space 3a. The trigger part 34 can be roughly cylindrical in shape, and the trigger part 34 is equivalent to being protruding within the housing space 3a.

[0165] The first part 31 may include a main body 311 and a molding part 312. The main body 311 is connected to the second part 32 and the trigger part 34. The molding part 312 is connected to the main body 311 and is located on the side of the trigger part 34 away from the cover space 3a, forming a buffer space 3b with the trigger part 34. In a first direction, the projection of the molding part 312 at least partially covers the projection of the buffer space 3b. The buffer space 3b is at least formed by the molding part 312 and the trigger part 34. The first direction may be parallel to the Z direction.

[0166] For example, the first part 31 can be approximately a body of revolution. The outer surface of the main body 311 can be approximately cylindrical. The molding part 312 can be disposed opposite to the triggering part 34; the two can be arranged in a first direction. The molding part 312 can be connected to the triggering part 34. It is understood that the molding part 312 can be directly connected to the triggering part 34, or the molding part 312 can be connected to the triggering part 34 through the main body 311.

[0167] Since the forming part 312 is located on the side of the trigger part 34 away from the third part 33, and the forming part 312 is used to form the buffer space 3b, the two sides opposite to the trigger part 34 are the cover space 3a and the buffer space 3b, respectively, and both spaces can provide conditions for the deformation of the elastic member 3.

[0168] For example, the top surface of the trigger portion 34 can serve as the wall of the buffer space 3b. The buffer space 3b may not weaken the structure of the trigger portion 34, allowing the trigger portion 34 to form a solid structure. In this case, the buffer space 3b and the trigger portion 34 may not coincide in the first direction (Z direction). In some other embodiments, the buffer space 3b may penetrate the trigger portion 34, forming a cover structure for the trigger portion 34. In this case, the buffer space 3b and the trigger portion 34 coincide in the first direction (Z direction).

[0169] It is understood that the trigger part 34 and the molding part 312 are used to form the buffer space 3b. The buffer space 3b can be formed by only the two, or it can be formed by the trigger part 34, the molding part 312 and the main body part 311. The specific configuration can be based on the structure of the first part 31.

[0170] In this example, the second part 32 serves as the sidewall of the cover space 3a of the elastic member 3. The second part 32 is prone to deformation and can serve as the main deformation structure of the elastic member 3. When the elastic member 3 is subjected to force, the deformation of the second part 32 can be relatively large. It is understood that the first part 31 and the third part 33 can also deform, and their deformation can be less than that of the second part 32.

[0171] Because the first part 31 has a buffer space 3b containing air, the buffer space 3b effectively weakens the structure of the first part 31, making the sidewall of the first part 31 forming the buffer space 3b more prone to deformation. Therefore, when the elastic member 3 is subjected to force, both the second part 32 and the first part 31 can deform; and the second part 32 will deform first as the primary deformation structure, while the third part 33 will deform as the primary deformation structure after the second part 32 has undergone a certain amount of deformation. This gives the elastic member 3 multi-stage deformation capability, resulting in a smoother change in the elastic force during deformation and reducing abrupt changes in the magnitude of the elastic force.

[0172] For example, in the keyboard 200, the first part 31 of the elastic member 3 is fixedly connected to the keycap 1, and the third part 33 of the elastic member 3 is fixedly connected to the base plate 10. The trigger part 34 is spaced apart from the base plate 10, and the trigger part 34 can be positioned facing the key switch 1021. The trigger part 34 is used to contact the key switch 1021, thereby triggering the key switch 1021. For example, the trigger part 34 can be located above the key switch 1021 in the Z direction.

[0173] The elastic element 3 can be used to fix the keycap 1 to the base plate 10 by adhesive bonding. For example, the first part 31 of the elastic element 3 is bonded to the keycap 1, and the third part 33 of the support element 2 is bonded to the base plate 10.

[0174] Furthermore, when keycap 1 is pressed, the second part 32 of elastic element 3 deforms, and keycap 1 moves towards base plate 10. Simultaneously, trigger part 34 moves towards base plate 10. When trigger part 34 contacts base plate 10, due to the buffer space 3b of first part 31, the first part 31 (buffer space 3b) can continue to deform until keycap 1 stops moving. Specifically, when key 20 is pressed, the deformation of the second part 32 provides the first stage of elastic force, thus providing the user with a first stage of tactile feedback. The deformation of the first part 31 (buffer space 3b) also prevents a sudden increase in the elastic force of elastic element 3 when trigger part 34 contacts base plate 10. The deformation of the first part 31 (buffer space 3b) provides the second stage of elastic force, thus providing the user with a second stage of tactile feedback. Therefore, when the user uses keyboard 200, elastic element 3 has a buffering capacity, and the user's fingers will not feel like they are hitting a hard plate. With increasing keystrokes, fingers are less prone to fatigue, making use more comfortable.

[0175] Understandably, since the support member 2 can deform, when the user presses the button 20, the elastic member 3 is also deformed by force. The support member 2 can deform synchronously and provide auxiliary support for the keycap 1, causing the keycap 1 to move towards the base plate 10. Furthermore, when the elastic member 3 deforms, the trigger part 34 moves towards the base plate 10 and contacts the button switch 1021 on the base plate 10, thereby triggering the button switch 1021 and triggering the button 20.

[0176] Understandably, when the user releases button 20, the elastic element 3, due to its elastic restoring force, can drive the keycap 1 to reset, causing it to move away from the base plate 10 until it returns to its unpressed height. Specifically, after button 20 is pressed to its lowest point, it can rebound, and the movement of the elastic element 3 during the rebound process can be roughly the opposite of the movement of the elastic element 3 when it is pressed.

[0177] In this embodiment, the keycap 1 is connected to the base plate 10 via the support member 2 and the elastic member 3. Each part of the keycap 1 has a support structure, ensuring that the keycap 1 can be reliably fixed within the keyboard 200 with minimal wobble and good stability. The keyboard 200 provides users with a better tactile experience and reduces user fatigue, thus improving the user experience.

[0178] When the keyboard 200 of this application embodiment is applied Figures 1 to 3 In any of the embodiments of the electronic device or Figure 4 The keyboard cover 2000 can reduce user fatigue during use, provide a good user experience, achieve a thin and light design, and has a low cost.

[0179] Please refer to the following: Figures 7 to 9 , Figure 9 yes Figure 8 An exploded view of part of the structure of the keyboard 200 shown from another perspective.

[0180] In some embodiments, the keycap 1 may include a plate 11 and a flange 12. The flange 12 is disposed around the plate 11 and protrudes relative to the plate 11 toward the base plate 10.

[0181] The keycap 1 may also include a first latching portion 13. The first latching portion 13 may be fixed to the side of the plate 11 facing the base plate 10. The first latching portions 13 may be arranged in groups, and a group may include two first latching portions 13. The first latching portion 13 may have a latching hole 131, which may be a semi-circular hole with an opening.

[0182] The keycap 1 may further include a second latching portion 14. The second latching portion 14 may be fixed to the side of the plate 11 facing the base plate 10. The second latching portions 14 may be arranged in groups, and a group may include two second latching portions 14. The second latching portion 14 may have a latching groove 141.

[0183] In some embodiments, the base plate 10 may include a first hook portion 103. The first hook portion 103 may be fixed to the support plate 101 and protrude toward the keycap 1. The first hook portions 103 may be arranged in groups, and a group may include two first hook portions 103, and the two first hook portions 103 may be arranged at intervals.

[0184] The base plate 10 may also include a second latch 104. The second latch 104 may be fixed to the support plate 101 and protrude toward the keycap 1. The second latches 104 may be arranged in groups, and a group may include two second latches 104, which may be spaced apart.

[0185] In some embodiments, the first support frame 21 of the support member 2 can be generally rectangular. The first end of the first support frame 21 may have a first locking rod 211. The first locking rod 211 can be a circular rod. Two first locking rods 211 can be grouped together, and the two first locking rods 211 can be coaxial. The second end of the first support frame 21 may have a second locking rod 212. Two second locking rods 212 can be grouped together, and the two second locking rods 212 in a group can be coaxial. A central hole 213 can be formed in the middle of the first support frame 21. The central hole 213 can be a circular hole. The central hole 213 can penetrate the first support frame 21. A rotating shaft 214 can be provided in the middle of the first support frame 21. The rotating shaft 214 can be located on both sides of the central hole 213.

[0186] Furthermore, the second support frame 22 of the support member 2 can be approximately rectangular in shape. The first end of the second support frame 22 can have a third locking rod 221. Two third locking rods 221 can be grouped together, and the two third locking rods 221 can be coaxial. The second end of the second support frame 22 can have a fourth locking rod 222. Two fourth locking rods 222 can be grouped together, and the two fourth locking rods 222 can be coaxial. A receiving hole 223 can be formed in the middle of the second support frame 22. The receiving hole 223 can be rectangular and can penetrate the second support frame 22. A rotating groove 224 can be formed in the middle of the second support frame 22. The rotating groove 224 can be located on both sides of the central hole 213 and communicate with the central hole 213.

[0187] In some embodiments, the rotation axis 214 of the first support frame 21 can be located in the rotation groove 224 of the second support frame 22, and the two can be rotatably connected. The first support frame 21 and the second support frame 22 can rotate relative to each other around the rotation axis 214, and the receiving hole 223 provides movement space for the relative rotation of the two.

[0188] The first latching rod 211 of the first support frame 21 is used to latch onto the first latching part 13 of the keycap 1 and is rotatably connected to the wall of the latching hole 131 of the first latching part 13. The second latching rod 212 of the first support frame 21 is used to engage with the first latching part 103 of the base plate 10. The first latching part 103 is used to limit the second latching rod 212 in a direction perpendicular to the base plate 10 (Z direction), and the second latching rod 212 can move relative to the first latching part 103 in the arrangement direction of the first latching part 103 and the second latching part 104 (such as the X direction).

[0189] The third latching rod 221 of the second support frame 22 is used to latch onto the second latching part 14 of the keycap 1. The second latching part 14 limits the third latching rod 221 in the direction perpendicular to the base plate 10 (Z direction), and the third latching rod 221 can move relative to the second latching part 14 in the arrangement direction of the first latching part 13 and the second latching part 14 (e.g., X direction). The fourth latching rod 222 of the second support frame 22 is used to engage with the second latching part 104 of the base plate 10. The second latching part 104 limits the fourth latching rod 222 in the direction perpendicular to the base plate 10 (Z direction), and the fourth latching rod 222 can move relative to the second latching part 104 in the arrangement direction of the first latching part 103 and the second latching part 104 (e.g., X direction).

[0190] In addition, the elastic element 3 can be located in the central hole 213 of the first support frame 21.

[0191] Therefore, when the keycap 1 and the base plate 10 move relative to each other, the first support frame 21 and the second support frame 22 can rotate relative to each other to provide auxiliary support for the keycap 1 and prevent the keycap 1 from deflecting.

[0192] It is understandable that the stiffness of keycap 1 can be greater than that of elastic element 3. When key 20 is subjected to force, the deformation of keycap 1 is less than that of elastic element 3. In some examples, keycap 1 can be a rigid structure. When keycap 1 is subjected to force, it can simultaneously apply the pressing force to support element 2 and elastic element 3, thereby pressing support element 2 and elastic element 3 simultaneously. At this time, the force of keycap 1 on elastic element 3 is basically along the direction perpendicular to the base plate 10, making the deformation of elastic element 3 more consistent. This is beneficial for keycap 1 to move in the direction perpendicular to the base plate 10, thereby preventing keycap 1 from deflecting when pressed and also improving the user's feel. It is understandable that when keycap 1 is subjected to force, keycap 1 can produce a small rigid deformation, and the deformation of keycap 1 can be much smaller than the deformation of support element 2 or elastic element 3.

[0193] Please refer to the following: Figure 7 , Figure 8 and Figure 10 , Figure 10 yes Figure 7 The elastic element 3 shown is a simplified cross-sectional view in some embodiments.

[0194] In some embodiments, the first portion 31 may have a connecting hole 313. The connecting hole 313 is used to connect the buffer space 3b with the space outside the buffer space 3b.

[0195] For example, the connecting hole 313 connects the buffer space 3b with the space on the side of the molding part 312 opposite to the buffer space 3b. The connecting hole 313 can be formed in the molding part 312. Since the molding part 312 is located on the side of the trigger part 34 opposite to the cover space 3a, forming the connecting hole 313 in the molding part 312 can connect the buffer space 3b with the space on the side opposite to the cover space 3a, that is, connect the buffer space 3b with the space on the top side of the molding part 312.

[0196] Understandably, the diameter of the connecting hole 313 can be small so that the forming part 312 can cover most of the area of ​​the buffer space 3b.

[0197] When the elastic element 3 deforms, after the second part 32 deforms, the trigger part 34 and the third part 33 are flush with the surface of the first part 31 (that is, the trigger part 34 and the third part 33 are flush with the surface of the first part 31). Figure 7When the base plate 10 contacts the keyboard 200, the sidewall of the buffer space 3b will be compressed, and the air in the buffer space 3b will be discharged from the connecting hole 313. At this time, the first part 31 can deform, so that the elastic force of the elastic element 3 against the outside will not suddenly increase, thus playing a buffering role. For the user, the user can feel the trigger part 34 bottoming out (contacting the base plate 10 of the keyboard 200), and the reaction force of the key 20 against the finger will not suddenly increase, but will increase gradually. The elastic element 3 can buffer when the user presses the key 20, and still provide the user with a stopping feel, so that the user has a good feel and is not easily fatigued.

[0198] In addition, the connection hole 313 makes the buffer space 3b easier to form, which in turn makes the production of the elastic element 3 simpler and cheaper.

[0199] In some other embodiments, the connecting hole 313 can connect the buffer space 3b and the cover space 3a. For example, the buffer space 3b and the cover space 3a are separated by a trigger portion 34 and a first portion 31; therefore, the connecting hole 313 can be formed in the separating structure between the buffer space 3b and the cover space 3a, thereby connecting the two. In this case, when the buffer space 3b deforms, the gas inside it can be discharged into the cover space 3a.

[0200] It is understandable that the third part 33 may be provided with a groove 331, which connects the cover space 3a to the outside of the elastic member 3. When the elastic member 3 deforms, the deformation of the second part 32 is larger, while the deformation of the third part 33 is smaller. The gas in the cover space 3a can be discharged to the outside through the groove 331 to avoid the gas affecting the deformation of the elastic member 3.

[0201] In some embodiments, in the keyboard 200, the keycap 1 may have a channel 15 (see [link to keyboard 200]). Figure 9 The guide groove 15 is used to connect the outer space of the first part 31 and the connecting hole 313. At this time, the guide groove 15 can connect the buffer space 3b through the connecting hole 313. When the elastic member 3 deforms, the gas in the buffer space 3b can flow out to the outside of the elastic member 3 through the guide groove 15, or be drawn into the buffer space 3b from the outside of the elastic member 3.

[0202] In some other embodiments, in the keyboard 200, the first part 31 is sealed to the keycap 1, and the keycap 1 blocks the connecting hole 313. At this time, by sealing the connecting hole 313 with the keycap 1, the buffer space 3b forms a closed cavity, thereby forming an air cushion structure for cushioning.

[0203] In some embodiments, please continue reading Figure 10, the main body portion 311 has a first surface 3111, the molding portion 312 has a second surface 3121, and the first surface 3111 and the second surface 3121 are smoothly connected. Among them, the first surface 3111 is the surface of the main body portion 311 facing away from the third portion 33. The second surface 3121 is the surface of the molding portion 312 facing away from the third portion 33. In other words, the surface of the main body portion 311 facing away from the third portion 33 is smoothly connected to the surface of the molding portion 312 facing away from the third portion 33, and the two can form a smooth surface. Exemplarily, the first surface 3111 and the second surface 3121 can be flush and form a flat surface.

[0204] At this time, the surface of the main body portion 311 facing away from the third portion 33 and the surface of the molding portion 312 facing away from the third portion 33 can serve as the end face of the first portion 31, so that the contact area between the first portion 31 and other components (keycap 1) is larger and the connection is more stable; moreover, the support of the elastic member 3 for the keycap 1 is also more stable. In addition, the structure of the elastic member 3 can be made simpler, the production of the elastic member 3 can be made simpler, and the cost is lower.

[0205] In some embodiments, in the first direction, the diameter of the projection of the buffer space 3b is R1, and the diameter of the projection of the first portion 31 is R2, where (R2 * 0.25) < R1 < (R2 * 0.5). Exemplarily, R1 = R2 * 0.3.

[0206] Exemplarily, the buffer space 3b can be a substantially cylindrical space. The height of the buffer space 3b can be less than its diameter. The height of the buffer space 3b can be the height in the first direction (Z direction), and the diameter of the buffer space 3b can be the diameter perpendicular to the first direction. The diameter of the first portion 31 can be the diameter perpendicular to the first direction. It can be understood that in some other embodiments, when the first portion 31 and / or the buffer space 3b is a non-circular structure, the diameter can be the equivalent diameter.

[0207] In this embodiment, by reasonably setting the dimensional relationship between the buffer space 3b and the first portion 31, the buffer space 3b has a suitable volume, so that the first portion 31 takes into account the buffer performance and the stop feeling during deformation.

[0208] In some embodiments, the elastic member 3 can be an integrally formed structural member. Exemplarily, the elastic member 3 can be formed by processes such as injection molding. After molding, the first portion 31, the second portion 32, the third portion 33, and the trigger portion 34 can be directly formed and enclose the cover space 3a and the buffer space 3b.

[0209] Please refer to Figure 11 , Figure 11 is Figure 7 a schematic cross-sectional view of the elastic member 3 shown in some other embodiments. Among them, Figure 11 The elastic element 3 in the embodiment may include Figure 10 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0210] Figure 11 The elastic element 3 and in the embodiment Figure 10 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the first part 31.

[0211] In some embodiments, the main body 311 may have a recess 3112. The recess 3112 may be located on the side of the main body 311 away from the third part 33. The recess 3112 and the buffer space 3b are arranged along a first direction, and the projection of the recess 3112 in the first direction covers the projection of the buffer space 3b in the first direction.

[0212] For example, the recess 3112 may be formed by a recess in the surface of the first portion 31 facing away from the third portion 33 toward the third portion 33. The diameter of the recess 3112 may be larger than the diameter of the buffer space 3b. For example, the recess 3112 may be connected to the buffer space 3b through a connecting hole 313.

[0213] In this embodiment, by setting the sink 3112, less material is used around the buffer space 3b, thereby making the first part 31 more flexible. When the elastic element 3 deforms and the trigger part 34 and the third part 33 are flush with the surface of the first part 31, the first part 31 and / or the trigger part 34 are easier to deform, thus having a better buffering effect, which is beneficial to setting the appropriate buffering capacity according to the user's feel requirements.

[0214] Please see Figure 12 , Figure 12 yes Figure 7 The elastic element 3 shown is a simplified cross-sectional view in some embodiments. Figure 12 The elastic element 3 in the embodiment may include Figure 10 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0215] Figure 12 The elastic element 3 and in the embodiment Figure 10 The main difference in the elastic element 3 of the embodiment lies in the setting of the buffer space 3b in the first part 31.

[0216] In some embodiments, the buffer space 3b is a sealed cavity.

[0217] For example, the buffer space 3b can be approximately ellipsoidal in shape. The major axis of the buffer space 3b can be perpendicular to the first direction (Z direction). In this case, the buffer space 3b is relatively flat in the first direction, and the sidewalls of the buffer space 3b are more easily deformed in the first direction. For example, when the buffer space 3b deforms, the two opposite walls of the buffer space 3b in the first direction move closer to each other, that is, the trigger part 34 and the forming part 312 move closer to each other. When the deformation of the buffer space 3b is large, the trigger part 34 and the forming part 312 can come into contact.

[0218] The buffer space 3b can contain gas. Since the buffer space 3b is closed, its sidewalls are equivalent to forming an airbag structure. When the elastic element 3 is compressed, the air inside the buffer space 3b is also compressed and plays a role in providing elasticity. This helps the first part 31 to provide appropriate support for the trigger part 34 and gives the buffer space 3b better buffering capacity.

[0219] Please see Figure 13 , Figure 13 yes Figure 7 The elastic element 3 shown is a simplified cross-sectional view in some embodiments. Wherein, Figure 13 The elastic element 3 in the embodiment may include Figure 12 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0220] Figure 13 The elastic element 3 and in the embodiment Figure 12 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the first part 31.

[0221] In some embodiments, the main body 311 may have a recess 3112. The recess 3112 may be arranged around the buffer space 3b.

[0222] For example, the sink 3112 may be formed by a recess in the surface of the first portion 31 facing away from the third portion 33 toward the third portion 33. The diameter of the sink 3112 may be larger than the diameter of the buffer space 3b.

[0223] For example, the sink 3112 and the buffer space 3b overlap in the first direction, so that the sink 3112 surrounds the periphery of the buffer space 3b. The forming part 312 can be used to form the bottom wall of the sink 3112. The height of the forming part 312 in the first direction can be lower than the surface of the first part 31 facing away from the third part 33, but is not strictly limited to this. In this case, the sink 3112 has little impact on the shape and deformation of the buffer space 3b, and the buffer space 3b can have better deformation buffering capacity.

[0224] In this embodiment, by setting the sink 3112, less material is used around the buffer space 3b, thereby making the first part 31 more flexible. When the elastic element 3 deforms and the trigger part 34 and the third part 33 are flush with the surface of the first part 31, the first part 31 and / or the trigger part 34 are easier to deform, thus having a better buffering effect, which is beneficial to setting the appropriate buffering capacity according to the user's feel requirements.

[0225] Please refer to the following: Figure 14a and Figure 14b , Figure 14a yes Figure 6 The diagram shown is a simplified representation of the working process of the elastic element 3 in the keyboard 200. Figure 14b yes Figure 14a The diagram shows the pressing force curve of the elastic element 3 during the pressing process.

[0226] in, Figure 14b The horizontal axis represents the stroke of the elastic element 3 during deformation, and the vertical axis represents the pressure applied.

[0227] The process from O to P3 represents the pressing of the elastic element 3.

[0228] In the section from O to P1, the elastic element 3 can deform slightly, and the pressing force gradually increases. In the section from P1 to P2, the elastic element 3 has a larger deformation, and the pressing force gradually decreases until the trigger part 34 of the elastic element 3 touches the bottom at point P2.

[0229] In the P2 to P3 segment, the buffer space 3b of the elastic element 3 will continue to deform, and the corresponding pressing force will initially remain almost unchanged. Then, the buffer space 3b of the elastic element 3 will no longer deform, and the pressing force will increase accordingly. For a typical elastic element 3, such as... Figure 14b As shown by the dashed line, after the trigger part of the elastic element bottoms out at point P2, the pressing force will increase directly with a larger curvature. Therefore, compared with a general elastic element, the elastic element 3 in this embodiment can buffer after bottoming out, resulting in a more gradual change in pressing force.

[0230] The process from P3 to P4 to P'1 to O' represents the rebound process of elastic element 3. This process is roughly the opposite of the process of elastic element 3 being pressed, and will not be described in detail in this embodiment.

[0231] Therefore, the elastic element 3 in this embodiment has good buffering ability, reducing user fatigue during keyboard 200 use and improving user experience.

[0232] Please refer to the following: Figure 15 and Figure 16 , Figure 15 yes Figure 6 The partial structure of the keyboard 200 shown is illustrated in a simplified cross-sectional view of some other embodiments. Figure 16 yes Figure 15The diagram shows a partial structural representation of the keyboard 200 in use according to some embodiments. Figure 15 The keyboard 200 in the embodiment may include Figure 7 Most of the technical features of the keyboard 200 in the embodiment are described below, mainly focusing on the differences between the two. Technical features that are the same in both will not be described again.

[0233] Figure 15 Keyboard 200 and in the embodiment Figure 7 The main difference in the keyboard 200 of the embodiment lies in the arrangement of the elastic element 3.

[0234] In some embodiments, the elastic member 3 may further include a buffer portion 35. The buffer portion 35 is fixedly connected to the third part 33 and is located on the side of the third part 33 opposite to the cover space 3a, and the buffer portion 35 is elastic.

[0235] For example, the buffer portion 35 may be generally annular. The buffer portion 35 may surround the third portion 33, and the thickness of the buffer portion 35 may be different from the thickness of the third portion 33. For example, the thickness of the buffer portion 35 may be less than the thickness of the third portion 33. In this case, the buffer portion 35 and the third portion 33 have approximately the same shape, making it easy to connect to the third portion 33. In some other embodiments, the buffer portion 35 may include a plurality of sub-portions, which may be spaced apart and arranged around the periphery of the third portion 33 and fixedly connected to the third portion 33.

[0236] For example, the buffer 35 is used to contact other components (support 2) to cushion the other components.

[0237] On the keyboard, such as Figure 15 When the keycap 1 is not pressed, the buffer portion 35 has a first distance from the keyboard 200; the elastic element 3 is partially sleeved in the center hole 213 of the first support frame 21, and the buffer portion 35 and the first support frame 21 have a distance in the first direction (Z direction). Figure 16 When keycap 1 is pressed, the distance between the buffer portion 35 and the keyboard 200 is less than the first spacing, and the support member 2 abuts against the buffer portion 35. The buffer portion 35 abuts against the first support frame 21 of the support member 2, and the first support frame 21 of the support member 2 squeezes the buffer portion 35. Therefore, during the pressing process of keycap 1, keycap 1 moves towards the base plate 10, the first support frame 21 rotates relative to the elastic member 3, and when keycap 1 is about to move to the lowest point, the first support frame 21 contacts the buffer portion 35 and gradually squeezes the buffer portion 35, causing the buffer portion 35 to be squeezed and deformed.

[0238] In this embodiment, the buffer part 35 buffers the second half of the movement of the keycap 1 toward the base plate 10 by contacting the support member 2, so as to realize the "soft landing" of pressing the keycap 1 and avoid the keycap 1 stopping suddenly when it reaches the lowest point. This avoids the sudden increase of the reaction force of the keycap 1 on the user and avoids the user feeling of pressing a hard plate, thereby improving the user's feel when using the keyboard 200 and reducing the user's fatigue during use.

[0239] In addition, since the buffer part 35 is a ring-shaped part, all parts of the ring-shaped surface of the buffer part 35 can contact the support member 2, thereby providing uniform buffering for the support member 2, which is beneficial to improving the buffering capacity of the buffer part 35.

[0240] Please continue reading. Figure 15 In some embodiments, the buffer portion 35 can be a plate-shaped structural member, with the surface of the buffer portion 35 facing away from the first portion 31 and the surface of the third portion 33 facing away from the first portion 31 flush. In this case, the buffer portion 35 is far from the first portion 31 and is positioned low. Other components only come into contact with the buffer portion 35 when they move close to the bottom of the elastic member 3. That is, in the keyboard, the first support frame 21 only comes into contact with the buffer portion 35 after rotating a large distance. Therefore, the buffer portion 35 buffers the last segment of movement of other components (support member 2).

[0241] In some embodiments, when the elastic element 3 is a one-piece molded structural component, the buffer portion 35 can be molded synchronously with other structures of the elastic element 3, making the manufacturing of the elastic element 3 simpler. Furthermore, no new components need to be added when assembling the keyboard 200, simplifying assembly.

[0242] In some embodiments, the elastic element 3 may also be provided with a buffer space 3b (not shown). The structure of the buffer space 3b can be referred to Figures 7 to 13 The relevant descriptions in the embodiments will not be repeated in this embodiment.

[0243] Please see Figure 17 , Figure 17 yes Figure 15 The elastic element 3 shown is a simplified cross-sectional view in some other embodiments. Figure 17 The elastic element 3 in the embodiment may include Figure 15 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0244] Figure 17 The elastic element 3 and in the embodiment Figure 15 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the buffer portion 35.

[0245] In some embodiments, the surface of the buffer portion 35 facing away from the first portion 31 and the surface of the third portion 33 facing away from the first portion 31 are spaced apart. The surface of the buffer portion 35 facing away from the first portion 31 is also the top surface of the buffer portion 35. The surface of the third portion 33 facing away from the first portion 31 is also the bottom surface of the third portion 33. In this configuration, the buffer portion 35 is relatively close to the first portion 31 and is positioned relatively high, essentially suspended. Other components can contact the buffer portion 35 when they move close to the third portion 33 of the elastic member 3. When the key 20 of the keyboard 200 is pressed, the first support frame 21 rotates to a certain extent and then contacts the buffer portion 35. After the support member 2 contacts the buffer portion 35, the buffer portion 35 will first bend and deform, and then be compressed and deformed, thereby providing appropriate cushioning for the support member 2.

[0246] Please see Figure 18 , Figure 18 yes Figure 15 The elastic element 3 shown is a simplified cross-sectional view in some embodiments. Figure 18 The elastic element 3 in the embodiment may include Figure 15 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0247] Figure 18 The elastic element 3 and in the embodiment Figure 15 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the buffer portion 35.

[0248] In some embodiments, the cross-section of the buffer portion 35 extends at least in a curved manner in the first direction. The cross-section of the buffer portion 35 may be a surface coplanar with the central axis of the buffer portion 35.

[0249] For example, the buffer portion 35 may include a first fixing portion 351, a deformable portion 352, and a second fixing portion 353. The first fixing portion 351, the deformable portion 352, and the second fixing portion 353 are connected sequentially. The first fixing portion 351 is fixed to the third portion 33. In the keyboard 200, the first fixing portion 351 and the second fixing portion 353 can be used to fixably connect to the base plate 10.

[0250] The first fixing part 351 and the second fixing part 353 can each be approximately flat ring structures. The deformable part 352 can also be approximately ring structures, and the cross-section of the deformable part 352 can extend in an arc. In this case, the deformable part 352 is equivalent to a raised part, and after being compressed, the deformable part 352 can first undergo bending deformation, which provides cushioning.

[0251] In the keyboard 200, the first support frame 21 can come into contact with the buffer part 35 after rotating to a certain extent. After the support member 2 comes into contact with the buffer part 35, the buffer part 35 will first bend and deform, and then be squeezed and deformed, thereby providing appropriate buffering for the support member 2.

[0252] Please see Figure 19 , Figure 19 yes Figure 15 The elastic element 3 shown is a simplified cross-sectional view in some embodiments. Wherein, Figure 19 The elastic element 3 in the embodiment may include Figure 15 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0253] Figure 19 The elastic element 3 and in the embodiment Figure 15 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the buffer portion 35.

[0254] In some embodiments, the buffer portion 35 can be a conical structure, extending along the periphery of the third portion 33 in a direction away from the third portion 33 and in a direction away from the first portion 31. The surface of the buffer portion 35 that connects to the third portion 33 is its inner annular surface, and the surface of the buffer portion 35 that is away from the third portion 33 is its outer annular surface. In other words, the height of the inner annular surface of the buffer portion 35 in the first direction is higher than the height of its inner annular surface in the first direction. The thickness of the buffer portion 35 can be uniform, but is not strictly limited to this.

[0255] At this time, the buffer part 35 is relatively close to the first part 31, and the position of the buffer part 35 is relatively high, so the buffer part 35 is essentially suspended. After the first support frame 21 rotates to a certain extent, it can contact the buffer part 35. After other parts (the first support frame 21) contact the buffer part 35, the buffer part 35 will first bend and deform, and then be squeezed and deformed, thereby providing appropriate buffering for the support member 2.

[0256] Please see Figure 20 , Figure 20 yes Figure 15 The elastic element 3 shown is a simplified cross-sectional view in some other embodiments. Figure 20 The elastic element 3 in the embodiment may include Figure 15 Most of the technical features of the elastic element 3 in the embodiment are described below, mainly focusing on the differences between the two. The technical features that are the same in both will not be repeated.

[0257] Figure 20 The elastic element 3 and in the embodiment Figure 15 The main difference in the elastic element 3 of the embodiment lies in the arrangement of the buffer portion 35.

[0258] In some embodiments, the thickness of the buffer portion 35 gradually increases from one end to the other in a direction perpendicular to the first direction. The surface of the top side of the buffer portion 35 is substantially inclined. For example, the thickness of the buffer portion 35 gradually increases in the Z direction as it extends along the X direction.

[0259] In the keyboard 200, the thickness of the buffer portion 35 near the first end of the first support frame 21 is greater than the thickness of the buffer portion 35 near the second end of the first support frame 21. That is, the thinner side of the buffer portion 35 is positioned near the second end of the first support frame 21, and the thicker side is positioned near the first end of the first support frame 21. At this time, the first end of the first support frame 21 can rotate relative to the second end, and the top surface of the buffer portion 35 is inclined. This means that when other components (the first support frame 21) come into contact with the buffer portion 35 through rotation, it facilitates synchronous contact between the surfaces of the other components (the first support frame 21) and the top surface of the buffer portion 35, thereby synchronously compressing all parts of the buffer portion 35 and causing synchronous deformation and buffering, thus making the buffering action of the buffer portion 35 smoother.

[0260] Please refer to the following: Figure 21a and Figure 21b , Figure 21a yes Figure 15 The diagram shows the working process of key 20 on keyboard 200. Figure 21b yes Figure 21a The graph shows the pressing force curve of the key 20 of the keyboard 200 during the pressing process.

[0261] in, Figure 21b The horizontal axis represents the travel distance of keycap 1, and the vertical axis represents the pressing force.

[0262] The process from O to P3 represents the pressing of button 20.

[0263] In the section from O to P1, the elastic element 3 can deform slightly, the pressing force gradually increases, and the keycap 1 can descend slightly. In the section from P1 to P2, the elastic element 3 has a larger deformation, the pressing force gradually decreases, and the keycap 1 continues to descend until the elastic element 3 (trigger part 34) contacts the base plate 10 at point P2.

[0264] In the section from P2 to P3, because the elastic element 3 has a buffer portion 35, the support element 2 will first contact the buffer portion 35, at which point the pressing force will remain almost unchanged. Then, the buffer portion 35 of the elastic element 3 will no longer deform, and the pressing force will increase accordingly. For a typical elastic element 3, such as... Figure 21b As shown by the dashed line, after the trigger part of the elastic element bottoms out at point P2, the pressing force will increase directly with a large curvature due to the lack of cushioning. Therefore, compared to ordinary elastic elements, the elastic element 3 in this embodiment can cushion the impact after bottoming out, resulting in a more gradual change in pressing force.

[0265] The process from P3 to P4 to P'1 to O' is the rebound process of button 20. This process is roughly the opposite of the process of button 20 being pressed, and will not be described in detail in this embodiment.

[0266] Therefore, the keys 20 of the keyboard 200 in this embodiment have good cushioning ability, reducing user fatigue during keyboard 200 use and improving user experience.

[0267] Please continue reading. Figure 21b .

[0268] The force at point P1 is the pressing and breaking force FP1, which is equal to the force required to fully press button 20, and the unit is grams (g).

[0269] Among them, the force at point P2 is the pressing force FP2, which is equal to the rebound force of button 20 when it first contacts trigger part 34, and the unit is grams (g).

[0270] Among them, the force at point P4 is the rebound force FP4, which is equal to the rebound force of button 20 when it is pressed down to the bottom and contacts the trigger part 34. The unit is grams (g).

[0271] Among them, the paragraph feel is equal to (P1-P2) / P1(%).

[0272] The press loss value Gap is defined as the difference between the pressing force FP2 and the rebound force FP4. Generally speaking, if the press loss value Gap is large, when button 20 needs to have a good tactile feedback, the value of FP2 needs to be low, which easily leads to a small rebound force FP4, resulting in a poor rebound feel for button 20. Conversely, when button 20 needs to have a good rebound feel, a large rebound force FP4 is required, which easily leads to a large pressing force FP2, resulting in a poor tactile feedback. Therefore, it is difficult to simultaneously achieve both the tactile feedback when pressing button 20 and the rebound feel of button 20.

[0273] Analysis shows that when the press loss value is smaller (FP2≈FP4), the impact on the tactile feedback is relatively small when changing the pressing force and rebound force, which is beneficial for balancing the tactile feedback when pressing button 20 and the rebound force when button 20 rebounds. Furthermore, the press loss value is negatively correlated with the volume of the cover space 3a of the elastic element 3.

[0274] Please see Figure 22 , Figure 22 yes Figure 7 The diagram shown is a simplified structural representation of the elastic element 3 in some embodiments.

[0275] In some embodiments, the third part 33 can be annular, the outer diameter of the third part 33 is R1a, and the inner diameter of the third part 33 is R1b, where R1b > (0.8 * R1a);

[0276] The first part 31 can be cylindrical, the outer diameter of the first part 31 is R2, the trigger part 34 is cylindrical, and the diameter of the trigger part 34 is R3, where (1 / 3) * R2 < R3 < (1 / 2) * R2;

[0277] The wall thickness of the second part 32 is w, where 0.25 mm < w < 0.35 mm;

[0278] In the first direction, the distance between the surface of the third part 33 facing away from the first part 31 and the trigger part 34 is L, and the height of the elastic member 3 is H, where 0.3 * H < L < 0.4 * H. Here, L can also be regarded as the bottoming distance of the trigger part 34.

[0279] In this embodiment, by defining the dimensions of the first part 31, the dimensional relationship between the first part 31 and the trigger part 34, the dimensions of the second part 32, and the position of the trigger part 34 in the elastic member 3, etc., the cover space 3a of the elastic member 3 has a relatively large volume, which is beneficial to making the pressing loss value of the elastic member 3 small, so that the key 20 of the keyboard 200 takes into account the paragraph feel when pressing the key 20 and the resilience when the key 20 rebounds.

[0280] In some embodiments, the included angle between the centerlines of the second part 32 and the third part 33 is A, where 140° < A < 160°; the second part 32 is connected to the first part 31 on the surface of the cover space 3a, and the included angle between the second part 32 and the first part 31 on the surface of the cover space 3a is B, where 110° < A < 150°. At this time, by further defining the included angle between the axes of the second part 32 and the third part 33, and the included angle between the second part 32 and the first part 31 on the surface of the cover space 3a, the second part 32 has an appropriate inclination degree, so that the second part 32 can be deformed under force with an appropriate force, thereby having a good paragraph feel and also taking into account making the cover space 3a have a relatively large volume, which is beneficial to improving the overall use feel of the elastic member 3.

[0281] In some embodiments, the elastic member 3 satisfies: 4 mm < R1b < 4.2 mm; 0.75 mm < L < 0.85 mm. By defining the inner diameter size of the third part 33 and the bottoming distance of the trigger part 34, it is beneficial to make the elastic member 3 have an appropriate size and an appropriate use feel.

[0282] The following will be described by way of 5 specific and non-limiting examples.

[0283] Please refer to Table 1, which shows the specifications of the elastic element 3 in five specific examples.

[0284] Table 1

[0285] Example 1 Example 2 Example 3 Example 4 Example 5 R1b 4.05 4.05 4.17 4.05 4.05 L 0.82 0.82 0.82 0.82 0.82 w 0.33 0.33 0.28 0.33 0.33 B 123° 123° 123° 133° 143° A 147° 147° 147° 157° 164° S 4.8908 5.0196 5.0669 5.0952 5.165 Gap 6.708 6.234 5.292 3.814 3.306

[0286] Where S is the cross-sectional area of ​​the cover space 3a, R1b is the inner diameter of the third part 33, L is the distance between the surface of the third part 33 away from the first part 31 and the trigger part 34, w is the wall thickness of the second part 32, B is the angle between the second part 32 and the surface of the first part 31 located in the cover space 3a, A is the angle between the axes of the second part 32 and the third part 33, and Gap is the pressing loss value.

[0287] It is understandable that the volume of the enclosure space 3a is directly proportional to its cross-sectional area. The larger the cross-sectional area of ​​the enclosure space 3a, the larger its volume. The cross-sectional area of ​​the enclosure space 3a can be the area of ​​a section of the enclosure space 3a that is coplanar with its centerline. For example, the cross-section of the enclosure space 3a can be the YZ plane passing through the centerline, i.e. Figure 22 The middle part is filled with gray.

[0288] like Figure 23 , Figure 23 This is a graph showing the relationship between the cross-sectional area of ​​the cover space 3a and the pressure loss value. The larger the cross-sectional area S of the cover space 3a, the smaller the pressure loss value Gap, which in turn helps the keyboard 200 to have a better feel.
