Description

Technical Field

[0001] This utility model relates to an aluminum alloy keyboard based on a Gasket structure. Background Technology

[0002] Gasket structures are commonly used in mechanical keyboards. The core of this design involves adding a soft foam pad between the keyboard base and the PCB board. This effectively reduces key noise and vibration, improving keyboard stability and typing feel. For example, Chinese patent CN222867501 U discloses a mechanical keyboard with a gasket structure. It achieves noise reduction and vibration damping through multi-layered cushioning and sound-absorbing structures such as silicone pads, under-switch pads, and sound-absorbing pads. However, the opening and assembly of each cushioning and sound-absorbing layer is quite difficult, and the support for the key components is relatively soft, leaving room for improvement in typing feel.

[0003] In recent years, aluminum alloy keyboards have become increasingly popular among esports and DIY enthusiasts due to their texture and stylish, versatile designs. To achieve a better user experience, a gasket structure has been incorporated into aluminum alloy keyboards. Furthermore, aluminum alloy keyboards possess a significantly stronger base shell than plastic keyboards, providing a superior structural foundation for supporting the key components.

[0026] The following is in conjunction with the appendix Figures 1 to 10 The following is a further description of the proposed solution:

[0027] This utility model discloses an aluminum alloy keyboard based on a Gasket structure, comprising an aluminum alloy base shell 1. On the aluminum alloy base shell 1, a base pad 2, a PCB board 3, a sound-absorbing pad 4, a positioning plate 5, a support plate 6, a key assembly 7, and a front panel 8 are sequentially arranged. The aluminum alloy base shell 1 is made of aluminum alloy profile, which is formed with an upper edge plate 11, a lower edge plate 12, and a base plate 13. Laterally extending grooves 14 are respectively provided on the upper edge plate 11 and the lower edge plate 12. The two ends of the aluminum alloy base shell 1 are respectively sealed by detachable end caps 9, which can be fixed by screws, magnets, etc. Using an aluminum alloy profile to form the base shell results in high structural strength, easy forming, and flexibility, meeting the needs of different shapes. Each layer of the components can be inserted from both ends of the base shell, making assembly and disassembly convenient. The upper edge plate 11 and lower edge plate 12 of the aluminum alloy base shell 1 are respectively provided with protrusions 15 for mounting the panel 8. The protrusions 15 are provided with magnetic blocks 151 for magnetic adsorption with the panel 8. The aluminum alloy base shell 1 and the panel 8 are connected by magnetic adsorption, which realizes quick installation and removal of the panel 8. Users can choose to replace the panel 8 with different patterns according to their own preferences, which meets the application needs of keyboard style DIY.

[0028] The support plate 6 has holes 60 corresponding to each button assembly 7. Several support bodies 61 are provided along the upper and lower edges of the support plate 6, each with a buffer sleeve 62. The support bodies 61 along the upper and lower edges of the support plate 6 are inserted into the end openings of the grooves 14. The buffer sleeves 62 fill the cross-section of the grooves 14. After the support plate 6 is in place, the buffer sleeves 62 and the grooves 14 are in static friction contact, ensuring a secure contact while also providing support and cushioning. The side of the button assembly 7 has an overlapping edge 71, which overlaps with the edge of the hole 60 after the button assembly 7 passes through it, thus supporting the button assembly 7. When the button assembly 7 is pressed, the pressure is distributed to each support body 61 and absorbed by the buffer sleeve, achieving a fast-response rebound feel and quiet operation, significantly improving the user experience.

[0029] Specifically, the support body 61 is a strip parallel to the edge of the support plate 6. There is a gap 63 between the strip and the support plate 6, and only the middle part of the strip is connected to the support plate 6. This structure is to allow the support body 61 to have a larger elastic deformation space. The buffer sleeve 62 includes a left sleeve 621 and a right sleeve 622. The left sleeve 621 and the right sleeve 622 are connected by a soft band 623. The left sleeve 621 and the right sleeve 622 are respectively used to cover the two ends of the strip. During installation, the left sleeve 621 is inserted into one end of the strip, and then the soft band 623 is stretched to give the right sleeve 622 enough space to be inserted into the other end of the strip. The soft band 623 constrains the left sleeve 621 and the right sleeve 622 to make them tight and not easy to fall off, especially during the process of the support plate 6 being embedded into the groove 14.

[0030] Furthermore, in order to obtain uniform force distribution and improve the buffering effect, four supports 61 are provided on the upper and lower edges of the support plate 6, and the supports 61 are spaced apart from each other. This reduces the material of the supports 61 and the buffer sleeve 62, and facilitates the assembly and disassembly of the supports 61 and the buffer sleeve 62. When the key components 7 at different positions on the keyboard are pressed, the supports 61 adjacent to the key component 7 share more of the deformation force.

[0031] Furthermore, the aluminum alloy base shell 1 is provided with a power board 16, a battery 17, and a battery compartment 18 for placing the battery 17. The battery compartment 18 consists of two symmetrically positioned grooves on the base plate 13, with one battery 17 placed in each groove. The power board 16 is electrically connected to the two batteries 17 respectively, and a charging interface seat 161 is provided at one end of its body. The outer side of the upper edge plate 11 is provided with an inwardly recessed insertion groove 111, and an opening communicating with the inner side of the aluminum alloy base shell 1 is provided in the insertion groove 111. The charging interface seat 161 passes through the opening.

[0032] Furthermore, a raised body 19 is provided at the rear of the bottom surface of the base plate 13. The raised body 19 tilts the key surface toward the user side. Anti-slip strips 10 are provided on the raised body 19 and the front of the bottom surface of the base plate 13, respectively, to ensure that the keyboard does not move arbitrarily when the user is typing.

[0033] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
