[0065] To enable those skilled in the art to better understand the technical solution of the present invention, the following description, in conjunction with specific embodiments and appendices, provides further details. Figure 1-10 The present invention will be described in further detail below.

[0066] In competitive gaming, the keyboard is the most commonly used input device. Due to the prolonged and frequent keystrokes, higher demands are placed on the keyboard's operability and comfort. Vibration damping is a crucial factor in this.

[0067] like Figures 1 to 7 As shown, the present invention provides a shock-absorbing foot pad 10 for a keyboard 1, see reference. Figure 2 , Figure 3 The shock-absorbing foot pad 10 includes a foot pad body 11, characterized in that the foot pad body is provided with holes 113, and when the shock-absorbing foot pad is compressed, the holes 113 deform.

[0068] As shown in the figure, the hole 113 constitutes a shock-absorbing structure. When the shock-absorbing pad is compressed (for example, the shock-absorbing pad is located at the bottom of the keyboard, and when the user applies pressure to the keyboard), the hole 113 of the shock-absorbing structure undergoes elastic deformation due to the compression, thereby absorbing the impact energy and reducing hand fatigue during operation, thus achieving a good cushioning effect.

[0069] Specifically, as one implementation, the hole is an opening that penetrates the main body of the foot pad, and multiple openings are provided on the main body of the foot pad. This design of multiple openings enhances the shock absorption effect of the foot pad.

[0070] To further enhance the cushioning function of the foot pad, it also includes recesses located at the edges of the top and / or bottom surfaces of the foot pad body, such as... Figure 2 As shown. By providing a recess 117 on the foot pad, the cushioning effect of the foot pad can be improved when the contact surface of the foot pad with the recess 117 is subjected to force, based on the structural design of the recess. Specifically, the recess 117 includes multiple recesses.

[0071] Furthermore, when the structural design simultaneously features an opening 113 and a recess 117, such as Figure 2 As shown, as an extended implementation, the design can be such that the openings on the main body of the foot pad are staggered with the concave areas on the bottom surface of the main body of the foot pad, so as to further improve the shock absorption effect of the foot pad.

[0072] Furthermore, considering that the shock absorption function is achieved through a perforated structure, the shape of the perforation also affects the shock absorption effect of the foot pad. In this shock absorption structure based on the perforated foot pad, the cross-sectional shape of the perforation is circular, polygonal, cross-shaped, star-shaped, or irregular. Specifically, the hole spacing is 0.3-2mm, and the perforation rate is 30%-60%. This is based on research findings on the shock absorption effect of the foot pad, which indicates that when the perforation spacing of the aforementioned shock absorption foot pad is 0.3-2mm, or the perforation rate is 30%-60%, it can effectively accommodate the cushioning effect when the user is using the keyboard.

[0073] When the hole 113 is an open structure, in order to better improve the shock absorption effect, as an improved embodiment, the hole 113 is composed of multiple open holes, which are distributed in a grid pattern, such as... Figure 3 The figure shown is a cross-sectional view of the main body 11 of the shock-absorbing pad 10. The main body of the pad has a structure with multiple openings 113. Each opening is a buffer unit. When the pad is compressed, the corresponding opening will deform due to the compression, thereby realizing the buffer function and achieving the shock absorption effect.

[0074] Furthermore, improvements can be made to the shock-absorbing structure, such as making each opening 113 hexagonal, for example... Figure 3 As shown, the overall cushioning structure of the foot pad can form a honeycomb structure; alternatively, each opening can be cylindrical, forming an approximately honeycomb-like circular array structure. This cushioning structure provides a more uniform stress distribution, thereby improving the overall cushioning effect of the foot pad.

[0075] Furthermore, considering that the shock absorption function is achieved based on the perforated structure, the orientation of the perforation also affects the shock absorption characteristics. Therefore, as an extended implementation, the perforation is opened in a direction perpendicular or parallel to the footpad surface, thereby providing different shock absorption effects.

[0076] Furthermore, considering that the shock absorption function is achieved based on the structure of the opening 113, the size of the opening also affects the shock absorption characteristics. Therefore, as an extended implementation, the diameter or side length of the opening can be specifically set to 0.5-3mm. As in the above embodiment, when the opening 113 is circular, its diameter is 0.5-3mm; when the opening 113 is hexagonal, its side length is 0.5-3mm. Further, the ratio of the opening diameter to the foot pad height can be specifically set to 0.6-0.9. The corresponding parameters can be adjusted to adjust the shock absorption effect according to different users' needs for different shock absorption effects.

[0077] Furthermore, the openings can be arranged in layers, meaning the multiple openings are arranged in a multi-layered structure, with the upper and lower layers of openings staggered. This structural design also improves the shock absorption effect of the foot pad.

[0078] Furthermore, when the hole 113 is a shock-absorbing structure composed of multiple openings, since the openings form cavities, elastic components can be filled inside the openings, i.e., inside the cavities, to form a shock-absorbing system, thereby achieving and adjusting the shock-absorbing effect of the shock-absorbing pad, such as... Figure 4 As shown.

[0079] Furthermore, as another extended embodiment, the holes are cavities disposed within the main body of the foot pad, and the main body of the foot pad has multiple cavities. Specifically, the multiple cavities can be interconnected, and the cavities can be filled with fluid. This structural design can also improve the shock absorption effect of the foot pad.

[0080] Specifically, such as Figure 5As shown, each cavity resembles a bubble, independent and closed. This cavity structure effectively enhances the shock absorption effect of the cushioning pad. Furthermore, considering that the cushioning function is achieved based on a multi-cavity structure, the cavity structure also affects the cushioning characteristics. Therefore, as an extended implementation, the multiple cavities can be interconnected, and the cavities can be filled with fluid. This allows adjustment of the cushioning effect of the pad by changing the density distribution of the cavity structure.

[0081] Furthermore, as another extended embodiment, the cavity is filled with an elastic component to form a shock-absorbing system. Specifically, the elastic component is a spring. Figure 4 As shown.

[0082] In addition to the various shock-absorbing embodiments described above, an airbag 114 structure may also be added to the aforementioned embodiments, such as... Figure 6 As shown, the airbag 114 structure and the opening form a dual shock absorption system, further improving the shock absorption effect.

[0083] To improve shock absorption, the material type of the shock-absorbing pad can be comprehensively considered. Specifically, the main body of the pad can be made of an elastic material with a hardness range of 35-70 Shore A. Specifically, the elastic material can be silicone or thermoplastic elastomer (TPE). Specifically, the hardness of the pad material can be designed with a gradient structure, with higher hardness in the connecting parts and lower hardness in the external contact parts.

[0084] The selection of materials is based on the following criteria: A. Silicone material (hardness 40-50 Shore A): It has excellent elasticity and durability, making it suitable for making foot pads with high cushioning requirements; B. Thermoplastic elastomer (TPE) (hardness 35-45 Shore A): lower cost, good processing performance, suitable for large-scale production; C. Hybrid Material Solution: The core area uses a higher hardness material (50-55 Shore A) to ensure support, while the edge area uses a lower hardness material (30-40 Shore A) to enhance cushioning.

[0085] To improve shock absorption, the material density of the shock-absorbing feet can also be considered comprehensively. Differentiated local cushioning characteristics can be achieved by adjusting the perforation density in different areas. Specifically, different perforation densities (113) can be set in different areas of the foot pad body. For example, increasing the perforation density in the foot pad area corresponding to frequently used keys provides stronger cushioning; while reducing the perforation density in the edge areas maintains stability during lateral movement. Alternatively, the hardness of the top surface of the foot pad connected to the keyboard bottom shell can be higher than the hardness of the bottom surface away from the keyboard. These implementation methods refine the shock absorption requirements of different areas and parts.

[0086] When using interactive handheld devices such as keyboards, in addition to considering the aforementioned cushioning and shock absorption effects to improve the user experience, it is also necessary to consider the inherent performance of the device itself, such as structural stability and durability. That is, the shock-absorbing structure cannot be too soft or easily deformed. Therefore, in addition to the structural stability of the keyboard or similar device, the shock-absorbing feet must also be stable. To this end, further improvements have been made to the structure of the shock-absorbing feet, by designing the main body of the feet in layers, such as... Figure 7 As shown, as an example, the main body of the foot pad is divided into at least two layers. The first layer 111, which is close to the contact surface of the keyboard or other devices, is a solid structure; the second layer 112 has a perforated structure 113. Further, the first layer 111 is made of a material with higher hardness, and the second layer 112 is made of a material with lower hardness. Further, when the layered structure is a multi-layered structure with more than two layers, starting from the first layer 111 close to the contact surface of the keyboard or other devices, the materials of each layer of the foot pad main body adopt a structural design with a gradually decreasing hardness value, thereby improving the shock absorption performance of the keyboard or other devices while ensuring the stability of the overall structure of the device.

[0087] In addition, refer to Figure 6 As a supplement to the above embodiments, to improve the convenience of detachable use of the shock-absorbing feet and devices such as keyboards, the shock-absorbing feet may also include a connecting structure, which is connected to the device. Specifically, the upper surface of the foot body has a connecting structure clearance, which can mate with a corresponding position on the keyboard bottom shell. The connecting structure is connected to the device by means of adhesive bonding, snap-fit, or interference fit.

[0088] The above descriptions of various embodiments introduce a type of shock-absorbing pad for keyboards.

[0089] The present invention also provides a shock-absorbing keyboard, see reference. Figure 8 The shock-absorbing keyboard includes a bottom shell, and the bottom shell is provided with a plurality of shock-absorbing feet as described in the above embodiments.

[0090] When a user types on the keyboard, the impact force is transmitted through the keyboard's bottom shell to the feet. The perforated structure 113 within the feet undergoes elastic deformation under vertical pressure, with the hole walls compressing against each other and expanding laterally. This absorbs some of the impact energy, prolongs the impact duration, and reduces the peak instantaneous impact force. Once the pressure is released, the perforated structure 113 returns to its original shape due to the material's elasticity, preparing for the next cushioning action. Due to the presence of the perforated structure 113, the feet have a controllable compression rate in the vertical direction, typically 25-50%, providing a significant cushioning effect while maintaining sufficient support. By using these shock-absorbing feet in the keyboard, the keyboard's vibration damping function is achieved, resulting in a vibration-damping keyboard.

[0091] This invention successfully solves the technical problem of relying solely on material selection for keyboard vibration damping by designing a regularly arranged or irregularly arranged perforation structure 113 inside the keyboard feet. In practical use, this vibration damping foot structure effectively absorbs the impact energy of keystrokes, significantly reducing the impact force transmitted to the user's hands and reducing hand fatigue during long periods of typing or gaming. Simultaneously, because the damping effect occurs at the overall keyboard level, it does not affect the internal switch structure, maintaining consistent triggering accuracy and stability. This design also boasts advantages such as simple manufacturing process, limited cost increase, and strong adaptability, allowing for wide application in various mechanical keyboard products, providing users with a healthier and more comfortable input experience.

[0092] As one implementation option, multiple feet are symmetrically distributed on the bottom of the keyboard, typically four, such as... Figure 8 As shown, this ensures the overall stability and even force distribution of the keyboard.

[0093] Furthermore, while the various embodiments described above utilize shock-absorbing feet to achieve keyboard vibration damping, these shock-absorbing feet, designed based on a damping structure, can also serve a decorative purpose by incorporating the design patterns of the keyboard and other devices. Specifically, for example... Figure 9 As shown, when the keyboard's bottom shell has a pattern, the shock-absorbing pads are installed according to specific points on the pattern. When the shape of the shock-absorbing pads matches the pattern frame, the pattern can display a three-dimensional and unique visual effect. Specifically, the shape of the shock-absorbing pads can also be designed and selected according to the pattern. For example, Figure 9 As shown, if the keyboard bottom shell is designed with a cobra pattern, the cobra pattern is laid out in conjunction with the keyboard's shock absorption structure, and the position of the cobra's eyes is arranged to correspond to the nodes where the keyboard needs to absorb shock. The shock absorption pads can be set at the corresponding node positions. Furthermore, the shape of the shock absorption pads can also be designed to resemble the eye of a cobra.

[0094] Furthermore, considering the vibration damping needs of different areas of the keyboard, vibration damping pads can be installed according to the specific positions of the keyboard keys. For example, in the field of gaming keyboards, the frequency of operation of different keyboard keys varies significantly depending on the usage scenario. If the up, down, left, and right arrow keys are used frequently, vibration damping pads can be installed at the positions corresponding to the arrow keys.

[0095] This invention also provides a keyboard vibration damping method, see reference. Figure 1-7 The keyboard includes a non-solid foot pad, which reduces vibration through deformation when the foot pad is compressed.

[0096] When a user types on the keyboard, the impact force is transmitted through the keyboard's bottom shell to the feet. Since these feet are not solid, they can be understood as having a perforated structure. Under vertical pressure, the perforated structure (113) undergoes elastic deformation, with the hole walls compressing against each other and expanding laterally. This absorbs some of the impact energy, prolongs the impact time, and reduces the peak instantaneous impact force. Once the pressure is released, the perforated structure (113) returns to its original shape due to the material's elasticity, preparing for the next cushioning action. Due to the presence of the perforated structure (113), the feet have a controllable compression rate in the vertical direction, typically 25-50%, providing a significant cushioning effect while maintaining sufficient support. By using these shock-absorbing feet in the keyboard, the keyboard's vibration damping function is achieved, resulting in a vibration-damping keyboard.

[0097] Specifically, as one implementation method, the method can configure the hole as an opening penetrating the main body of the foot pad, with multiple openings provided on the main body of the foot pad. This multiple opening structure design enhances the shock absorption effect of the foot pad.

[0098] To further enhance the cushioning function of the foot pad, the cushioning method also includes providing a recess at the edge of the top surface and / or bottom surface of the foot pad body. By providing a recess 117 on the foot pad, when the contact surface of the foot pad with the recess 117 is subjected to force, the cushioning effect of the foot pad can also be improved based on the structural design of the recess. Specifically, there are multiple recesses 117.

[0099] Furthermore, when the structure design has both openings 113 and recesses 117, the openings on the main body of the foot pad and the recesses on the bottom surface of the main body of the foot pad are staggered to further enhance the shock absorption effect of the foot pad.

[0100] Furthermore, the cross-sectional shape of the opening is set to be circular, polygonal, cross-shaped, star-shaped, or irregular. Specifically, the hole spacing is 0.3-2mm, and the opening ratio is 30%-60%. This is based on research findings on the shock absorption effect of the shock-absorbing pads. When the hole spacing of the above-mentioned shock-absorbing pads is 0.3-2mm, or the opening ratio is 30%-60%, it can well adapt to the cushioning effect when the operator uses the keyboard.

[0101] To further enhance the shock absorption effect, the holes 113 are composed of multiple openings, which are distributed in a grid pattern, such as... Figure 3 The figure shown is a cross-sectional view of the main body 11 of the shock-absorbing pad 10. The main body of the pad has a structure with multiple openings 113. Each opening is a buffer unit. When the pad is compressed, the corresponding opening will deform due to the compression, thereby realizing the buffer function and achieving the shock absorption effect.

[0102] Furthermore, each opening 113 can be hexagonal, forming a honeycomb structure overall for the cushioning structure of the foot pad; or, each opening can be cylindrical, forming a circular array structure resembling a honeycomb. This cushioning structure provides a more uniform stress distribution to the foot pad, thereby improving its overall cushioning effect.

[0103] Furthermore, it can be specifically set that when the opening 113 is circular, its diameter is 0.5-3mm, and when the opening 113 is hexagonal, its side length is 0.5-3mm.

[0104] Furthermore, the ratio of the opening diameter to the foot pad height can be specifically set to 0.6-0.9. This allows for adjustment of the corresponding parameters to meet the different cushioning needs of different users.

[0105] Furthermore, the openings can be arranged in layers, with the upper and lower layers of openings staggered. This structural design can also improve the shock absorption effect of the foot pad.

[0106] Furthermore, when the hole 113 is a shock-absorbing structure composed of multiple openings, since the openings form cavities, elastic components can be filled inside the openings, i.e. inside the cavities, to form a shock-absorbing system, thereby achieving and adjusting the shock-absorbing effect of the shock-absorbing pad.

[0107] In addition to the shock absorption embodiments described above, an airbag 114 structure can be added to each of the aforementioned embodiments. The airbag 114 structure and the opening form a dual shock absorption system to further improve the shock absorption effect.

[0108] Furthermore, as another extended embodiment, in this method, the hole can be configured as a cavity within the main body of the foot pad, and multiple cavities can be provided on the main body of the foot pad. Specifically, the multiple cavities can be interconnected, and the cavities can be filled with fluid. This structural design can also improve the shock absorption effect of the foot pad.

[0109] Furthermore, as another extended embodiment, the cavity is filled with an elastic component to form a shock-absorbing system. Specifically, the elastic component is a spring. Figure 4 As shown.

[0110] Furthermore, the method can be configured to differentiate local cushioning characteristics by adjusting the perforation density in different areas. Specifically, different perforation densities 113 can be set in different areas of the foot pad body. For example, the perforation density can be increased in the foot pad area corresponding to frequently used keys to provide stronger cushioning; while the perforation density can be reduced in the edge area to maintain stability during lateral movement. Alternatively, the hardness of the top surface of the foot pad connected to the keyboard bottom shell can be higher than the hardness of the bottom surface away from the keyboard. The above implementation methods can precisely meet the needs of shock absorption effects in different areas and parts.

[0111] When using interactive handheld devices such as keyboards, in addition to considering the aforementioned cushioning and shock absorption effects to improve the user experience, it is also necessary to consider the inherent performance of the device itself, such as structural stability and durability. That is, the shock-absorbing structure cannot be too soft or easily deformed. Therefore, in addition to the structural stability of the keyboard or similar device, the shock-absorbing feet must also be stable. To this end, further improvements have been made to the structure of the shock-absorbing feet, by designing the main body of the feet in layers, such as... Figure 7 As shown, as an example, the main body of the foot pad is divided into at least two layers. The first layer 111, which is close to the contact surface of the keyboard or other devices, is a solid structure; the second layer 112 has a perforated structure 113. Further, the first layer 111 is made of a material with higher hardness, and the second layer 112 is made of a material with lower hardness. Further, when the layered structure is a multi-layered structure with more than two layers, starting from the first layer 111 close to the contact surface of the keyboard or other devices, the materials of each layer of the foot pad main body adopt a structural design with a gradually decreasing hardness value, thereby improving the shock absorption performance of the keyboard or other devices while ensuring the stability of the overall structure of the device.

[0112] In addition, considering the vibration damping needs of different positions on the keyboard, vibration damping pads can be set according to the position of specific keys on the keyboard.

[0113] Furthermore, while the various embodiments described above utilize shock-absorbing pads to achieve keyboard vibration damping, these pads, designed based on the vibration damping structure, can also serve a decorative purpose in conjunction with the design patterns of the keyboard and other devices. Specifically, when the keyboard's bottom shell has a pattern, the shock-absorbing pads are installed at specific points on the pattern. When the shape of the shock-absorbing pads is combined with the pattern frame, the pattern can exhibit a three-dimensional and unique visual effect. Specifically, the shape of the shock-absorbing pads can also be designed and selected according to the pattern. For example, if the keyboard's bottom shell features a cobra pattern, the cobra pattern is laid out in conjunction with the keyboard's vibration damping structure, and the cobra's eyes are positioned corresponding to the nodes on the keyboard requiring vibration damping. The shock-absorbing pads can then be placed at these corresponding node positions. Furthermore, the shape of the shock-absorbing pads can also be designed to resemble a cobra's eye.

[0114] Through the description of the above embodiments, the shock absorption method, through the design of a unique shock absorption structure, not only improves the keyboard's shock absorption effect, but also enhances the keyboard's shape and structure based on the unique structural design, greatly improving the user experience.

[0115] The above description is merely a preferred embodiment of the present invention, and the specific embodiments described above are not intended to limit the present invention. Various modifications and variations can be made within the scope of the technical concept of the present invention. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present invention.
