Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a keyboard with suspension and buffer function. Background Technology

[0002] With the rapid development of the mechanical keyboard market, users are constantly raising their requirements for keyboard feel, shock absorption, and lifespan. To solve the problems of strong vibration feedback and a stiff feel when typing on traditional keyboards, a suspension structure is installed inside the keyboard to suspend the inner cartridge. This structure is gradually being applied to keyboard design. By suspending the inner cartridge inside the keyboard shell, the suspension component absorbs the vibration generated by typing, thereby optimizing the user experience.

[0003] In the aforementioned prior art, the suspension structure uses elastic arms to support the inner liner and works with soft connecting columns to achieve shock absorption. Although this improves the feel and shock absorption effect to some extent, it still has key technical defects.

[0004] In existing technologies, because the suspension structure is mainly distributed on the sides of the inner tube, and cushioning is achieved through the local deformation of the elastic arm and the soft connecting column during typing, the inner tube is prone to regional deformation or twisting when subjected to uneven or localized striking forces, rather than settling smoothly as a whole. This localized deformation not only affects the consistency of the key feel, but also may cause damage to internal components (such as the PCB board and positioning plate) due to stress concentration after long-term use, thus shortening the keyboard's lifespan. Therefore, a keyboard with a suspension cushioning function is provided to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard with a suspension and buffer function to address the shortcomings of existing technologies, thereby solving the technical problem that the inner shell of existing suspended keyboards deforms during typing.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A keyboard with suspension and buffer function includes a base and a keyboard housing mounted on the base. The inner wall of the keyboard housing and the top surface of the base together form a buffer chamber. The buffer chamber is equipped with an inner tube and several suspension and buffer mechanisms for suspending the inner tube. When the inner tube is subjected to force, it sinks as a whole and is buffered by the suspension and buffer mechanisms.

[0007] Furthermore, the keyboard housing includes a first support base and a second support base, both of which are disposed on the base, and also includes a top cover fixedly disposed on the top of the first support base and the second support base.

[0008] Furthermore, the inner sides of the first support base and the inner sides of the second support base are each formed with several clearance grooves for accommodating the suspension buffer mechanism, and each suspension buffer mechanism is installed in a different clearance groove.

[0009] Furthermore, the inner liner includes a positioning plate, a sandwich filling, and a PCB board stacked sequentially from top to bottom within the buffer chamber. The PCB board is fixedly installed with the positioning plate, and multiple key shafts are installed on the top surface of the positioning plate. The edge of the positioning plate is simultaneously connected to several suspension buffer mechanisms for vertical movement.

[0010] Furthermore, a base cotton is installed between the PCB board and the base, and an anti-static cotton layer is provided on the surface of the base cotton.

[0011] Furthermore, the suspension buffer mechanism installed on the first support base includes a vertically arranged guide column, the top of the guide column is connected to the first support base, the bottom end is provided with a limiting member, the edge of the positioning plate is formed with an extension extending to the side, the extension is slidably disposed on the guide column, and the guide column is surrounded by an elastic member placed between the limiting member and the extension to apply an upward pushing force to the extension.

[0012] Furthermore, the top of the guide post is provided with a threaded rod coaxially arranged, and also includes a knurled nut fixedly arranged on the first support seat and placed above the relief groove, with the threaded rod and the knurled nut being threadedly connected; the bottom surface of the limiting member is formed with a screw groove.

[0013] Furthermore, the elastic element is a spring or a silicone sleeve.

[0014] Furthermore, the bottom of the first support base and the base, as well as the bottom of the second support base and the base, are fixedly connected by multiple first screws, and the top of the first support base and the bottom surface of the top cover, as well as the top of the second support base and the bottom surface of the top cover, are fixedly connected by multiple second screws.

[0015] Furthermore, the bottom of the first support base is formed with a long strip-shaped positioning protrusion, and the top surface of the base is formed with a positioning groove for the positioning protrusion to be inserted.

[0016] The beneficial effects of this utility model are: 1. This keyboard uses several suspension and buffer mechanisms to suspend the inner cartridge within the buffer chamber. When the user types on the keyboard, the inner cartridge sinks as a whole under the force, causing the suspension and buffer mechanisms to deform. This deformation absorbs the pressure generated when typing and applies an upward buffering force to the inner cartridge, thus achieving cushioning and shock absorption and improving the user experience.

[0017] 2. When this suspension and buffer mechanism is used in magnetic axis keyboards, it can ensure a soft and bouncy key feel, and because the whole structure is lowered, there will be no deformation, so it will not affect the accuracy of the keys (especially the RT accuracy in existing magnetic axis keyboards).

[0018] 3. The inner chamber is lowered as a whole, so it will not deform. Moreover, the components of the inner chamber are relatively stationary, and only the suspension and buffer mechanism deforms. This effectively avoids long-term deformation of the inner chamber itself, which could lead to damage to the components. This not only improves the user experience but also extends the lifespan of the keyboard. Attached Figure Description

[0025] The following is a detailed description of a keyboard with a suspension and buffer function according to the present invention, with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, an embodiment of the keyboard with suspension and buffer function of this utility model includes a base 1 and a keyboard shell installed on the base 1. The inner wall of the keyboard shell and the top surface of the base 1 together form a buffer chamber. The buffer chamber is equipped with an inner tube 5 and a plurality of suspension and buffer mechanisms 6 for suspending the inner tube 5. The suspension and buffer mechanisms 6 are used to suspend the inner tube 5 and to buffer the pressure of the inner tube 5 when it sinks as a whole after being subjected to force. The keyboard shell includes a first support 2 and a second support 3. The first support 2 and the second support 3 are respectively fixedly installed on the two length sides of the base 1. It also includes a top cover 4 fixedly installed on the top of the first support 2 and the second support 3.

[0027] By incorporating several suspension and buffer mechanisms 6, the inner cartridge 5, located within the buffer chamber, is suspended. When a user types on the keyboard, the inner cartridge 5 sinks under pressure, causing the suspension and buffer mechanisms 6 to deform. This deformation absorbs the pressure generated during typing and applies an upward cushioning force to the inner cartridge 5, thus buffering and reducing vibration and improving the typing experience. The overall sinking of the inner cartridge 5 prevents it from deforming, and since the components of the inner cartridge 5 remain relatively stationary, only the suspension and buffer mechanisms 6 deform. This effectively prevents long-term deformation of the inner cartridge 5, which could damage components. In addition to improving the typing experience, this also extends the lifespan of the keyboard.

[0028] In addition, when this suspension and buffer mechanism is used in magnetic axis keyboards, it can ensure a soft and bouncy key feel, and because the whole body is lowered, there will be no deformation, so it will not affect the accuracy of the keys (especially the RT accuracy in existing magnetic axis keyboards).

[0029] In this embodiment, the inner sides of the first support base 2 and the second support base 3 are each formed with a plurality of clearance grooves 22 for accommodating the suspension buffer mechanism 6, and each suspension buffer mechanism 6 is respectively installed in a different clearance groove 22. By setting the clearance grooves 22 to accommodate the suspension buffer mechanism 6, the internal structure of the keyboard is made more compact, the utilization rate of the internal space of the keyboard is improved, and manufacturing costs are saved.

[0030] Furthermore, the inner chamber 5 includes a positioning plate 51, a core 52, and a PCB board 53 stacked sequentially from top to bottom within the buffer chamber. The PCB board 53 is fixedly mounted to the positioning plate 51. Multiple key shafts 54 are mounted on the top surface of the positioning plate 51, and the edges of the positioning plate 51 are simultaneously connected to several suspension buffer mechanisms 6 for vertical movement. When assembling this keyboard, the top of the first support base 2 and the top of the second support base 3 are first fixedly mounted to the bottom surface of the top cover 4. Then, the inner chamber 5 is placed between the first support base 2 and the second support base 3. Subsequently, several suspension buffer mechanisms 6 are installed in different clearance slots 22, and the several suspension buffer mechanisms 6 are simultaneously slidably connected to the edges of the positioning plate 51. Finally, the bottom of the first support base 2 and the bottom of the second support base 3 are fixedly mounted to the base 1, completing the assembly of this keyboard.

[0031] In addition, a bottom cotton 9 is filled between the PCB board 53 and the base 1. By filling the bottom of the buffer cavity with the bottom cotton 9, the bottom cotton 9 absorbs and blocks the reflection and propagation of sound vibration waves in the buffer cavity without affecting the feel of use, thereby greatly reducing or even eliminating cavity noise and ensuring a purer sound for the buttons. A layer of anti-static cotton 10 is provided on the surface of the bottom cotton 9. The anti-static cotton 10 is used to prevent static electricity from damaging the various microelectronic components on the PCB board 53, thus improving the protection effect.

[0032] As can be seen from the combined drawings, the suspension buffer mechanism 6 is installed from top to bottom on the first support 2 and the second support 3. Because the inner liner 5 is suspended in the buffer chamber under the action of the suspension buffer mechanism 6, there are no other structures in the chamber below the inner liner 5 (i.e., the bottom of the buffer chamber). Therefore, when the bottom cotton 9 and antistatic cotton 10 are installed at the bottom of the buffer chamber, they will not be blocked by the suspension buffer mechanism 6 or other structures. If the suspension buffer mechanism 6 is installed from bottom to top to support the inner liner 5, holes and slots need to be made for the bottom cotton 9 and antistatic cotton 10 to be installed (without holes and slots, they will be blocked by the suspension buffer mechanism 6). Therefore, the top-down installation of the suspension buffer mechanism 6 not only provides suspension support and buffering for the inner liner 5, but also ensures that the integrity of the bottom cotton 9 and antistatic cotton 10 is not damaged, allowing them to fully fill the chamber below the inner liner 5, further improving the effect of eliminating cavity sound.

[0033] The suspension buffer mechanism 6 on the first support 2 and the suspension buffer mechanism 6 on the second support 3 are structurally identical. The suspension buffer mechanism 6 installed on the first support 2 includes a vertically arranged guide post 61, with a threaded rod 62 coaxially arranged at the top of the guide post 61, and a knurled nut 63 fixedly installed on the first support 2 and positioned above the relief groove 22. The threaded rod 62 is threadedly connected to the knurled nut 63. After placing the guide post 61 in the relief groove 22 and aligning the threaded rod 62 with the knurled nut 63, the guide post 61 is tightened, thereby tightening the threaded rod 62 to the knurled nut 63, and the guide post 61 is then fixedly installed in the relief groove 22. Alternatively, the threaded rod 62 can be directly threadedly connected to the first support 2, which also achieves the same effect of fixed installation.

[0034] In this embodiment, the edge of the positioning plate 51 is formed with an extension 55 extending to the side. The extension 55 is slidably disposed on the guide post 61. A limiting member 64 is provided at the bottom end of the guide post 61. An elastic member 66 is arranged around the guide post 61 and placed between the limiting member 64 and the extension 55 to apply an upward pushing force to the extension 55. The limiting member 64 is disc-shaped or has other shapes with dimensions larger than the radial diameter of the guide post 61. Under the combined action of the fixed guide post 61 and the elastic member 66 providing elastic support, the positioning plate 51 is suspended in the buffer chamber. The installation method of lifting from top to bottom does not affect the space at the bottom of the buffer chamber at all.

[0035] When this keyboard is used, the elastic element 66 undergoes compression deformation. This deformation absorbs the pressure exerted on the positioning plate 51 when the keyboard is pressed, preventing the positioning plate 51 from deforming and allowing the inner casing 5 to sink as a whole, avoiding regional deformation or individual key deformation. Furthermore, by wrapping the elastic element 66 around the guide post 61 and cooperating with the limiting element 64 at the bottom of the guide post 61, the elastic element 66 is prevented from falling downwards, while also ensuring that it does not shift or deviate during compression deformation.

[0036] The elastic element 66 can be a spring or a silicone sleeve, or it can be any soft material with elasticity such as PORON cotton, foam, or cloth. The cushioning force can be adjusted by replacing the elastic element 66 with one of different elasticities. Alternatively, the elastic element 66 can be replaced with a hard material such as a metal or plastic component according to the user's preference, so that the keyboard can completely eliminate the cushioning and achieve adjustable softness and hardness (i.e., the softness and hardness of the keystrokes), changing the feel based on the user's needs.

[0037] The bottom surface of the limiting component 64 is formed with a screw groove 65, which can be a slotted slot, a cross slot, a star-shaped slot, or an internal hexagonal slot. The screw groove 65 allows a screwdriver to engage with the guide post 61, and the guide post 61 can be rotated by turning the screwdriver, which facilitates the fixed installation of the guide post 61.

[0038] To facilitate keyboard assembly, the bottom of the first support base 2 and the base 1, as well as the bottom of the second support base 3 and the base 1, are fixedly connected by multiple first screws 7. The top of the first support base 2 and the bottom of the top cover 4, as well as the top of the second support base 3 and the bottom of the top cover 4, are fixedly connected by multiple second screws 8. During assembly of the first support base 2, the second support base 3, the base 1, and the top cover 4, the multiple first screws 7 and the multiple second screws 8 are tightened to secure them, making the keyboard not only easy to assemble but also providing high structural strength.

[0039] To improve the accuracy of assembly, a long strip-shaped positioning protrusion 21 is formed at the bottom of the first support base 2, and a positioning groove 11 is formed on the top surface of the base 1 for the positioning protrusion 21 to be inserted. After the positioning protrusion 21 is inserted into the positioning groove 11, the mounting hole on the base 1 for the first screw 7 to pass through will automatically align with the threaded hole at the bottom of the first support base 2 and the bottom of the second support base 3. Under the action of the positioning protrusion 21 and the positioning groove 11, the accuracy and efficiency of keyboard assembly are improved.

[0040] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
