[0025] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0027] In the design and manufacturing process of keyboard key structures, the reliability and precision of the internal connections of the keyboard keys are among the technical issues affecting the key operation feel and stability. For example, in related technologies, the keyboard key structure may include a keycap 1, a support member 2, and a base plate 3. The support member 2 may include an outer connector 201 and an inner connector 202. The outer connector 201 and the inner connector 202 can be cross-connected to form a scissor-like structure. The upper part of the outer connector 201 can connect to the sliding groove structure on both sides of the bottom of the keycap 1. This connection allows the keycap 1 to move vertically when pressed, while restricting its lateral displacement. The lower part of the outer connector 201 can engage with the base plate 3. This allows the support member 2 to open and close like scissors, thereby realizing the up-and-down movement of the keycap 1.

[0028] If the connection between the support 2 and the keycap 1 or the base plate 3 is not tight enough or the manufacturing tolerance is too large, the keycap 1 will slightly shift during the pressing process, causing the keycap 1 to wobble or tilt, affecting the typing feel and stability. If the connection between the support 2 and the keycap 1 or the base plate 3 is tight or the manufacturing tolerance is small, the keycap 1 will experience additional resistance when pressed, resulting in sticking or uneven typing.

[0029] The button structure provided in this application embodiment can solve the problem of poor wobbling or jamming of the keycap 1 during the pressing process due to connection and fit issues.

[0030] The first aspect of this application provides a button structure, such as... Figure 1 and Figure 2 As shown, it may include a keycap 1; a support member 2, which may include a main body 201a and a first cantilever structure 201b. The first cantilever structure 201b may include a fixed end 201e and a free end 201f. The free end 201f can be fixedly connected to the main body 201a through the fixed end 201e. The free end 201f can contact the inner wall of the keycap 1. The free end 201f can undergo elastic deformation relative to the main body 201a. The free end 201f can apply a force to the keycap 1. The total frictional force on the free end 201f comes from the inner wall of the keycap 1.

[0031] The key structure provided in this application embodiment can be composed of a keycap 1 and a support member 2, and can be applied to various types such as membrane keyboards, mechanical keyboards, and laptop keyboards. Among them, the keycap 1 is the part that the user presses, and it can have a cavity inside. The cavity has an inner wall structure, and the shape, size, and surface texture of the keycap 1 can be flexibly designed according to actual needs.

[0032] The support member 2 provides support for the keycap and can be set inside the cavity of the keycap 1 to enable the keycap 1 to move up and down. It includes a main body 201a and a first cantilever structure 201b. The support member 2 can be a scissor-shaped structure formed by combining an outer connector 201 and an inner connector 202, a V-shaped spring structure, or an elastic structure formed by combining a plate and a spring. The main body 201a provides a stable framework for the support member 2 and can be set on the base plate 3 of the keycap structure to provide stable support. The main body 201a can take various forms, such as a rectangular frame, a plate, or an irregularly shaped block structure. The first cantilever structure 201b is a component of the support member 2 and includes a fixed end 201e and a free end 201f. The fixed end 201e can be connected to the main body 201a, while the free end 201f can contact the inner wall of the keycap 1.

[0033] The first cantilever structure 201b can be an elastic structure made of a thin metal sheet. One end (fixed end 201e) is fixed to the main body 201a by welding or riveting, and the other end (free end 201f) is bent and contacts the inner wall of the keycap 1. When the keycap 1 is subjected to force and moves laterally, the free end 201f can undergo elastic deformation to eliminate the gap. Alternatively, the first cantilever structure 201b can be a plastic injection-molded first cantilever structure 201b. The fixed end 201e is embedded inside the main body 201a for fixed connection, and the free end 201f can be arc-shaped. When the keycap 1 moves, the free end 201f elastically deforms to adjust the contact state with the keycap 1. Alternatively, the first cantilever structure 201b can be made of rubber. The fixed end 201e is connected to the main body 201a by adhesive. The free end 201f is relatively soft and can effectively fill the gap through its own elastic deformation when the keycap 1 moves laterally.

[0034] The free end 201f approaches and makes physical contact with the inner wall of the keycap 1, allowing it to apply a force to the keycap 1 through elastic deformation. This force can be pressure or thrust, and its direction can be perpendicular to the inner wall of the keycap 1. When the free end 201f undergoes elastic deformation such as bending, compression, or stretching relative to the body 201a through the fixed end 201e, it can store and release energy, thereby generating a force that can be transmitted to the keycap 1. For example, when the keycap 1 moves (such as when a user presses it), the contact point between the free end 201f and the inner wall of the keycap 1 displaces, causing the free end 201f to elastically bend or deform. The strain energy generated by the deformation is converted into a force that acts directly on the keycap 1. This force can eliminate the lateral gap between the support 2 and the keycap 1, helping the keycap 1 maintain balance during movement and reducing wobbling or offset.

[0035] The free end 201f can be the tip of the first cantilever structure 201b, and its shape is conical or spherical. It directly contacts a point on the inner wall of the keycap 1 to form a point contact. Alternatively, the free end 201f can be planar and fit against the inner wall of the keycap 1 to form a surface contact. Or, one edge of the free end 201f can contact the inner wall of the keycap 1 to form a line contact.

[0036] The fixed end 201e can be the part that is fixedly connected to the main body 201a for securing the first cantilever structure 201b to the main body 201a, allowing the first cantilever structure 201b to elastically deform with the fixed end 201e as a fulcrum. The free end 201f can be the end of the first cantilever structure 201b, contacting the inner wall of the keycap 1, and can elastically move relative to the main body 201a. The fixed end 201e can be a protrusion on the first cantilever structure 201b, which is fixed by being inserted into the corresponding hole in the main body 201a through an interference fit, similar to a pin connection. Alternatively, a screw connection can be used, where the fixed end 201e can be provided with a threaded hole, and the main body 201a has a through hole at a corresponding position, and the fixed end 201e of the first cantilever structure 201b is fastened to the main body 201a together with screws. Alternatively, the fixed end 201e can also be a structure with barbs. During installation, the barbs are engaged in the slots of the main body 201a to achieve a fixed connection between the first cantilever structure 201b and the main body 201a.

[0037] During key usage, when the keycap 1 moves up and down (e.g., pressing and releasing), the support member 2, through the action of the first cantilever structure 201b, prevents the keycap 1 from shifting or wobbling in the horizontal direction (lateral direction), keeping the keycap 1 on a predetermined movement trajectory, thereby improving the accuracy and reliability of key operation. For example, in the scissor-switch keyboard keycaps in related technologies, the first cantilever structure 201b of the support member 2 can be set on one side of the keycap 1 or symmetrically set on both sides. When the keycap 1 is pressed, the free end 201f of the first cantilever structure 201b will generate an inward force due to elastic deformation, pressing tightly against the inner wall of the keycap 1, counteracting the generated lateral external force, and restricting the keycap 1 to the vertical movement direction, improving the accuracy of key operation.

[0038] The free end 201f can be spaced apart from the main body 201a, and the total frictional force on the free end 201f originates from the inner wall of the keycap 1. That is, in any position of the free end 201f in its natural state (not pressed) or in an elastically deformed state (during pressing), a physical gap can exist between the free end 201f and the main body 201a structure. This gap ensures that no part of the free end 201f makes physical contact with the main body 201a structure throughout its entire stroke path. Since there is no relative motion or contact pressure between them, no frictional force is generated. During pressing and resetting, when the free end 201f undergoes slight relative motion with respect to the keycap 1, the mating surface of the free end 201f can rub against the corresponding contact surface of the inner wall of the keycap 1. The total frictional force experienced by the free end 201f throughout the entire movement can all come from its interaction with the contact interface with the inner wall of the keycap 1, while the contribution of the main body 201a structure to the movement resistance of the free end 201f can be zero.

[0039] Because a safe distance can exist between the free end 201f and the main body 201a, even at maximum pressing stroke or rebound, the two can avoid hard collisions or unexpected contact. This effectively avoids the common sticking and sluggishness issues that occur when the keycap 1 is pressed due to unstable contact friction, thus improving the smoothness and consistency of the key feel.

[0040] In some embodiments of this application, the first cantilever structure 201b is used to eliminate the lateral gap between the keycap 1 and the support member 2 during movement; the trajectory of the elastic deformation has a non-intersecting path with the main body 201a.

[0041] When the free end 201f undergoes elastic deformation relative to the main body 201a, the trajectory of the free end 201f does not intersect or overlap with the structure of the main body 201a itself. That is, during elastic deformation, the spatial path of the free end 201f will not pass through the solid portion of the main body 201a, allowing the free end 201f to undergo normal elastic deformation and effectively eliminate lateral gaps. For example, the first cantilever 201b structure can be spaced apart from the main body 201a on the same plane, or stacked vertically and spaced apart.

[0042] The free end 201f of the first cantilever structure 201b can abut against the inner wall of the keycap 1 through elastic deformation, achieving dynamic contact. This allows for real-time compensation of the lateral gap of the keycap 1, preventing it from wobbling during pressing and improving the consistency of the typing feel. Lateral gap refers to the void or looseness in the horizontal direction (perpendicular to the key pressing direction) between the keycap 1 and the support member 2. A larger lateral gap makes the keycap 1 more prone to shifting and shaking, affecting the typing feel.

[0043] When keycap 1 is subjected to a lateral force, such as the offset caused by a finger striking the key, the free end 201f generates a counterforce through elastic deformation, pushing keycap 1 back into its original position, thereby eliminating lateral wobble or gaps between keycap 1 and support 2. Simultaneously, during the process of compensating for the lateral displacement of keycap 1, the projection area of ​​the main body 201a's solid structure and the projection area of ​​the deformation trajectory of the free end 201f do not overlap; that is, the elastic deformation trajectory does not intersect, overlap, or interfere with the main body 201a. This avoids motion interference with the main body 201a when the free end 201f deforms towards it, thus reducing the risk of collision. This ensures smooth key movement, preventing keycap 1 from jamming during pressing and providing users with a better key operation experience.

[0044] In some embodiments, the free end 201f can apply a target force to the inner wall of the keycap 1 through the restoring force of elastic deformation; the target force can be greater than zero.

[0045] The first cantilever structure 201b can be made of a plastic or metal material with a certain degree of elasticity. The fixed end 201e can be connected to the main body 201a, and the free end 201f can maintain pre-pressed contact with the keycap 1 to apply a target force greater than zero. This ensures that the keycap 1 has no free wobbling space in any state, eliminating lateral gaps.

[0046] For example, when keycap 1 is not subjected to external force, the free end 201f can rely on its own elastic restoring force to continuously and stably apply a target force to the inner wall of keycap 1, maintaining a tight contact between the two. When keycap 1 is subjected to a lateral offset force, the free end 201f will undergo further elastic deformation. As the degree of deformation increases, the reverse force also increases accordingly, thereby pushing keycap 1 back to its original position, ensuring that keycap 1 always moves on a predetermined trajectory. By introducing a first cantilever structure 201b with elastic restoring force into the support member 2, and allowing its free end 201f to continuously apply a target force to the inner wall of keycap 1, the left-right wobbling or tilting caused by offset can be reduced, while making the key press action smoother and reducing the feeling of sticking.

[0047] Furthermore, after long-term use, keycap 1 will develop tiny gaps due to wear. The free end 201f can automatically generate additional elastic deformation due to its elastic pre-compression characteristics to compensate for the gaps caused by wear, continuously maintain stable contact with the inner wall of keycap 1, and ensure the long-term stable operation of the key structure. The magnitude of the target force can be determined by the elastic modulus, thickness, or length of the material of the first cantilever structure 201b, and can be kept greater than zero. This is not limited here.

[0048] In some embodiments, the first cantilever structure 201b can be integrally formed with the main body 201a through the fixed end 201e, and the free end 201f can have a deformation space between it and the main body 201a.

[0049] The first cantilever structure 201b can be integrally formed with the main body 201a through the fixed end 201e to form an external connector 201. The first cantilever structure 201b and the main body 201a can be made of materials with certain strength and toughness, such as plastic or alloy materials, and can be integrally formed through injection molding. The injection molding process can ensure the firmness of the connection between the first cantilever structure 201b and the main body 201a, avoiding the impact on button performance caused by loose connection in traditional connection methods (such as welding and bonding).

[0050] The first cantilever structure 201b can extend from one side of the main body 201a. The fixed end 201e can be integrally formed with the main body 201a, while the free end 201f is suspended and can extend towards the inner wall of the keycap 1. A deformation space can be provided between the free end 201f and the main body 201a, allowing for elastic bending deformation. This deformation space provides sufficient elastic deformation space for the first cantilever structure 201b, enabling the free end 201f to deform smoothly under stress without interfering with the main body 201a. This effectively eliminates the lateral gap between the keycap 1 and the support member 2 and prevents key jamming during pressing.

[0051] In some embodiments, the first cantilever structure 201b can be a pair, and the distance between the free ends 201f of the pair of first cantilever structures 201b can be adapted to the internal space size of the keycap 1. The elastic deformation of the free end 201f can occur within the deformation space defined between the free end 201f and the body 201a.

[0052] A pair of first cantilever structures 201b can be symmetrically arranged on both sides of the main body 201a. The distance between the free ends 201f of the pair of first cantilever structures 201b matches the internal space dimensions of the keycap 1, ensuring that the free ends 201f can effectively abut against the inner wall when the keycap 1 moves laterally, without interfering with the vertical movement of the keycap 1. For example, the distance between the pair of first cantilever structures 201b is equal to the width of the inner wall of the keycap 1, or the distance is slightly larger than the width of the inner wall of the keycap 1, but does not interfere with the vertical movement of the keycap 1. Thus, the pair of free ends 201f constrain the keycap 1 from both sides, forming a clamping effect. Through this dual-point dynamic support method, more comprehensive and stable control of the keycap 1 is achieved. When the free ends 201f are subjected to external force, the range of elastic deformation is limited to the space area formed between the free ends 201f and the main body 201a, and does not exceed this space range. The limited deformation space ensures that the deformation of the free ends 201f does not exceed a reasonable range, avoiding collisions with other components.

[0053] By employing a pair of symmetrically arranged cantilever structures, a restoring force can be applied simultaneously to both sides of the keycap 1, thereby more effectively preventing the keycap 1 from tilting or shifting to one side and improving overall stability. Even if the keycap 1 has certain assembly errors or is affected by slight external forces, the free ends 201f on both sides can dynamically compensate through their respective elastic deformation, reducing the sticking and shaking caused by offset.

[0054] In some embodiments, the support member 2 may include an external connector 201, and the external connector 201 may be provided with a first notch 201c. The first notch 201c can separate the external connector 201 to form a first cantilever structure 201b and a main body 201a; the first notch 201c may be U-shaped.

[0055] The external connector 201 can be made of materials with certain strength and toughness, such as plastic or alloy, and is injection molded. A first notch 201c can be provided on one side edge or opposite sides of the external connector 201. The first notch 201c can be U-shaped, resembling the shape of the English letter "U," with one open end and two opposite sides. That is, the middle is recessed, while the two sides retain material connection. The presence of the first notch 201c makes the external connector 201 locally thinner and narrower, thus forming an elastically deformable part, namely the first cantilever structure 201b. The first cantilever structure 201b can be a flexible arm segment cut from the U-shaped notch. The fixed end 201e of the first cantilever structure 201b remains connected to the main body 201a, and the free end 201f can extend to the vicinity of the inner wall of the keycap 1 and contact it.

[0056] When the keycap 1 is slightly misaligned, the free end 201f of the first cantilever structure 201b will bend and deform under the pressure of the inner wall of the keycap 1. This deformation occurs within the elastic space defined by the U-shaped notch. After the key is released, the first cantilever structure 201b returns to its original shape due to the elasticity of the material itself, continuing to conform to the inner wall of the keycap 1 and maintaining a stable guiding function. By setting the first notch 201c, the elastic deformation of the first cantilever structure 201b will not interfere with the main body 201a, ensuring smooth key travel and avoiding jamming. The elastic coefficient of the first cantilever structure 201b can be precisely controlled by adjusting the depth and width of the U-shaped notch, optimizing the key feel; however, this is not limited here.

[0057] In some embodiments, the free end 201f can form point contact or line contact with the inner wall surface of the keycap 1.

[0058] Point contact means that the free end 201f and the inner wall surface of the keycap 1 make contact at a single point. This contact method concentrates the contact force on a single point. For example, the free end 201f can be a spherical protrusion that contacts a tiny plane on the inner wall of the keycap 1 to form point contact. Alternatively, the free end 201f can be a sharp conical structure whose tip contacts the inner wall of the keycap 1 to achieve point contact. Or, a hemispherical rubber protrusion can be provided on the free end 201f to contact the inner wall of the keycap 1, forming point contact.

[0059] Line contact means that the free end 201f and the inner wall surface of the keycap 1 are in contact along a line. For example, the free end 201f can be a long strip-shaped protrusion, with its edge contacting the inner wall of the keycap 1 to form a line contact. Alternatively, the surface of the free end 201f can be machined into an arc-shaped edge, contacting the corresponding arc-shaped surface of the inner wall of the keycap 1 to form a line contact. Or, the free end 201f can be made into a strip-shaped structure with a certain width, with one side contacting the inner wall of the keycap 1 to form a line contact.

[0060] The inner surface of keycap 1 can be a smooth plane, a groove with guide rails, or a specially treated area. The end face of the free end 201f can maintain a micro-interference of Max 0.03mm with the inner wall of keycap 1, which is not limited here.

[0061] In the related technologies, keycap 1 is prone to problems such as wobbling, sticking, and unstable feel due to lateral gaps in its key structure. If the contact area is too large, it will increase friction, affecting key smoothness. If there is no contact or poor contact, the misalignment of keycap 1 cannot be effectively eliminated.

[0062] The key structure provided in this application embodiment allows the contact between the free end 201f and the inner wall of the keycap 1 to be designed as either point contact or line contact. This method reduces the frictional area between the free end 201f and the inner wall of the keycap 1, thereby reducing friction. It can effectively eliminate lateral gaps while reducing the contact area and friction, making the keycap 1 move more flexibly and smoothly, and reducing the occurrence of jamming.

[0063] In some embodiments, the first cantilever structure 201b can be L-shaped, the free end 201f can extend in a direction away from the main body 201a, and the surface of the free end 201f facing the keycap 1 can be a convex arc surface.

[0064] The first cantilever structure 201b can extend from one side of the main body 201a in an L-shaped bend. The L-shape resembles the English letter "L" and consists of two perpendicular parts. For example, one part of the first cantilever structure 201b extends horizontally and connects to the main body 201a (the part where the fixed end 201e is located), while the other part extends vertically upward (the part where the free end 201f is located), forming a standard L-shape. Alternatively, the two parts of the L-shape can be connected by an arc-shaped transition, making the overall structure smoother and reducing stress concentration.

[0065] The free end 201f can extend in a direction away from the main body 201a, bringing it closer to the inner wall of the keycap 1. The surface of the free end 201f facing the keycap 1 has an outwardly convex arc shape, which makes the contact between the free end 201f and the inner wall of the keycap 1 smoother. The arc surface can be circular, elliptical, or other adaptable curves to make its surface smooth and reduce friction. The L-shaped structure allows the free end 201f to better penetrate the internal space of the keycap 1, such as the internal groove structure of the keycap 1. The arc surface design makes the contact smoother and reduces sliding resistance.

[0066] In some embodiments, such as Figure 3 and Figure 4 As shown, the support member 2 may also include a second cantilever structure 201d, which may have the same structure as the first cantilever structure 201b; the first cantilever structure 201b may be located at the first end of the main body 201a, and the second cantilever structure 201d may be located at the middle of the main body 201a.

[0067] The support member 2 may also include a second cantilever structure 201d identical to the first cantilever structure 201b. The first cantilever structure 201b and the second cantilever structure 201d may be respectively disposed at the first end and the middle of the main body 201a, thereby forming a multi-point support and constraint system. For example, the first cantilever structure 201b may dock with the groove inside the keycap 1, and the second cantilever structure 201d may dock with the inner wall of the keycap 1. The first cantilever structure 201b and the second cantilever structure 201d may each be a pair, and the first cantilever structure 201b and the second cantilever structure 201d may be integrally formed on the main body 201a of the support member 2 without additional assembly.

[0068] Two pairs of identical cantilever structures work together during the movement of keycap 1, resulting in more even force distribution during pressing and resetting. This provides users with smoother and more comfortable key feedback. When the user presses keycap 1, the first cantilever structure 201b and the second cantilever structure 201d undergo elastic deformation simultaneously. The resulting elastic forces cooperate to counteract lateral displacement. Compared to a single pair of cantilever structures, the force distribution is more even, resulting in better constraint on keycap 1.

[0069] In some embodiments, such as Figure 5 and Figure 6 As shown, the button structure may further include: a base plate 3, which may include a pair of oppositely arranged snap-fit ​​parts 301, and an external connector 201 may further include a pair of snap-fit ​​arms 203, wherein the pair of snap-fit ​​parts 301 may be connected to the pair of snap-fit ​​arms 203 respectively; wherein each snap-fit ​​arm 203 may be provided with a second notch 203c, and the snap-fit ​​arm 203 may form a first part 203a and a second part 203b through the second notch 203c, and the first part 203a may be connected to the snap-fit ​​part 301.

[0070] The base plate 3 can be located at the bottom of the button structure, and can be made of metal or hard plastic. It has a pair of oppositely arranged snap-fit ​​parts 301, which can be L-shaped or columnar. The snap-fit ​​parts 301 are used for detachable or plug-in connection with the outer connector 201 of the support member 2.

[0071] The external connector 201 may include a pair of snap-fit ​​arms 203. A second notch 203c on the snap-fit ​​arm 203 can divide it into a first part 203a and a second part 203b. The second notch 203c can be U-shaped or rectangular. The second notch 203c allows the snap-fit ​​arm 203 to have elastic space. The first part 203a, which is used to connect with the snap-fit ​​part 301 of the base plate 3, has a certain deformation capability. The second part 203b, which is away from the snap-fit ​​part 301, can provide elastic support for the first part 203a.

[0072] During the installation of the snap-fit ​​arm 203 and the snap-fit ​​part 301, the second notch 203c allows the first part 203a to undergo a slight elastic deformation. The elasticity of the first part 203a allows a certain pre-tightening force to be generated during the connection process, which can make the snap-fit ​​part 301 and the snap-fit ​​arm 203 fit tightly, making it less prone to loosening and facilitating installation and disassembly.

[0073] In some embodiments, the surface of the first portion 203a facing the snap-fit ​​portion 301 can be an arc surface recessed in the direction of the second notch 203c, and the outer connector 201 located on the arc surface can be provided with a third abutment end, which can form point contact or line contact with the snap-fit ​​portion 301.

[0074] The surface of the first part 203a facing the latching part 301 can be designed by the mold to be a concave arc surface towards the second notch 203c. That is, the surface of the first part 203a facing the latching part 301 presents an inwardly concave arc shape. The concave arc surface can be a semi-circular arc surface, an elliptical arc surface, or an irregular arc shape. At the position corresponding to the arc surface of the outer connector 201, a hemispherical or semi-cylindrical third contact end can be integrally formed. When the third contact end contacts the latching part 301, it can form a point contact or a line contact. For example, the end face of the free end 201f can maintain an interference of Max 0.03mm with the inner wall of the keycap 1, which is not limited here. During installation, the latching arm 203 of the outer connector 201 can be aligned with the latching part 301 of the base plate 3. Pressing the outer connector 201 will cause the arc surface of the first part 203a to undergo elastic deformation, and the third contact end will be embedded into the latching part 301 to achieve a stable connection that is not easy to loosen. The first part 203a of the snap-fit ​​arm 203 is designed as a concave arc surface to improve its flexible deformation capability. At the same time, during the movement of the keycap 1, the point contact or line contact with the base plate 3 can reduce the frictional resistance, making the movement of the keycap 1 smoother and avoiding jamming.

[0075] This application provides a keyboard, which may include: a housing, the housing may include multiple mounting areas; multiple key structures, the multiple key structures may be respectively disposed in the multiple mounting areas, the key structures may include keycaps 1; a support member 2, including a main body 201a and a first cantilever structure 201b, the first cantilever structure 201b may include a fixed end 201e and a free end 201f, the free end 201f may be fixedly connected to the main body 201a through the fixed end 201e, the free end 201f may be in contact with the inner wall of the keycaps 1, the first cantilever structure 201b is used to eliminate the lateral gap between the keycaps 1 and the support member 2 during movement; wherein, the free end 201f can undergo elastic deformation relative to the main body 201a, and the trajectory of the elastic deformation has a non-intersecting path with the main body 201a.

[0076] Keyboards can be of various types, including membrane keyboards, mechanical keyboards, and laptop keyboards, and can be used on electronic devices such as laptops, desktop computers, and game consoles. A keyboard includes a housing that supports the entire keyboard structure. Inside the housing are multiple mounting areas, each corresponding to a key position. The key structure includes a keycap 1 and a support 2. The keycap 1 is the part pressed by the user, and the support 2 supports the keycap 1 and guides its up-and-down movement.

[0077] The support member 2 includes a main body 201a and a first cantilever structure 201b. The first cantilever structure 201b has a fixed end 201e and a free end 201f. The free end 201f is connected to the main body 201a through the fixed end 201e and contacts the inner wall of the keycap 1. The first cantilever structure 201b has elastic deformation capability. During the movement of the keycap 1, the free end 201f undergoes elastic deformation to eliminate lateral gaps. The elastic deformation trajectory does not intersect with the movement path of the main body 201a, thus avoiding structural interference.

[0078] When a key is pressed, the opening and closing movement of the support 2 causes the keycap 1 to move downward. If the keycap 1 shows a slight deviation or wobbling tendency, the free end 201f of the first cantilever structure 201b undergoes elastic deformation. This deformation occurs on a trajectory that does not intersect with the movement path of the main body 201a. After deformation, the free end 201f continues to adhere to the inner wall of the keycap 1, playing a guiding and stabilizing role. After the key is released, the free end 201f returns to its original position due to the elasticity of the material, maintaining dynamic support for the keycap 1.

[0079] By ensuring that the first cantilever structure 201b remains in contact with the inner wall of the keycap 1, it effectively prevents the keycap 1 from wobbling or tilting. Even if there are certain assembly errors or manufacturing tolerances, the first cantilever structure 201b can dynamically compensate through elastic deformation, reducing reliance on high-precision manufacturing processes. At the same time, the non-intersecting path ensures that the deformation of the first cantilever structure 201b will not interfere with the normal operation of the scissor assembly, reducing jamming caused by interference.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
