[0025] Please refer to Figures 1-7 The utility model relates to a kind of air cushion vibration damping mechanical keyboard structure with adjustable air volume, including key cap 2, face cover 3, switch shaft 4, positioning plate 5, middle plate 6, PCB plate 7, air bag main body 1 and bottom shell 8, the bottom shell 8 is equipped with accommodating cavity 81 with opening upwards, positioning plate 5, middle plate 6, PCB plate 7, air bag main body 1 are installed in accommodating cavity 81, positioning plate 5, middle plate 6, PCB plate 7, air bag main body 1 are sequentially arranged from top to bottom, face cover 3 is covered on bottom shell 8, switch shaft 4 is arranged on positioning plate 5, the pin (not shown in the drawing) of switch shaft 4 is welded connection by passing middle plate 6 and PCB plate 7, key cap 2 is arranged on switch shaft 4, air bag main body 1 is on the bottom of PCB plate 7.

[0026] The utility model discloses a kind of air bag main body 1 are set to the bottom of PCB plate 7, and form an integral whole with PCB plate 7, effectively slow down the vibration when knocking key by air bag main body 1, avoid damaging keyboard due to long-term vibration, improve the service life of keyboard as a whole.

[0027] Further, the material of the air bag main body 1 is soft, such as silicone rubber, which covers the size of the keyboard key area. The air bag main body 1 is provided with a gas valve 14, and the air bag main body 1 is provided with an air bag cavity 11 inside for storing gas. The gas valve 14 is arranged on one side of the air bag main body 1, and the gas valve 14 is in communication with the air bag cavity 11. External gas enters the air bag cavity 11 through the gas valve 14, inflates the air bag main body 1, adjusts the amount of gas to change the size of the buoyancy, and the hand feeling when pressing the key is different. The air bag main body 1 needs to be adjusted by an inflation tool (not shown in the figure). The inflation tool is not limited by shape or material except for the gas nozzle specification.

[0028] Further, the upper surface of the air bag main body 1 is an inclined surface 12, which is inclined at a certain angle towards the user. The inclined surface 12 is parallel to the PCB plate 7. The appropriate inclination angle of the inclined surface 12 helps to maintain the natural angle of the wrist, reduces the pressure on the wrist and fingers during long-time typing, and reduces fatigue.

[0029] Further, the inclined surface 12 is provided with a plurality of muscle strip air chambers 13 penetrating the air bag cavity 11. The muscle strip air chambers 13 are integrated with the air bag main body 1. During use, the gas valve 14 is connected to an external gas source to inflate the air bag cavity 11 and the muscle strip air chambers 13. The muscle strip air chambers 13 enhance the shaping force of the inflated air bag main body 1.

[0030] In this embodiment, the ribbed air chambers 13 are continuously arranged along the length of the surface of the airbag body 1, forming a structural reinforcement for the airbag body 1 and improving its bending resistance and strength. The ribbed air chambers 13 protrude from the upper surface of the airbag body 1, and the airbag body 1 rests against the bottom of the PCB board 7 through the ribbed air chambers 13, causing the PCB board 7 to float. The ribbed air chambers 13 are arranged in a rectangular row on the upper surface of the airbag body 1, with consistent lateral and longitudinal spacing between adjacent ribbed air chambers 13. When the airbag body 1 is inflated, the ribbed air chambers 13 evenly press against the bottom of the PCB board 7, making the force on the PCB board 7 more even, thus giving the entire keyboard keys buoyancy.

[0031] Since the pins of the switch shaft 4 (not shown in the figure) will pass through the PCB board 7 when the switch shaft 4 is installed on the PCB board 7, in this embodiment, the rib air chamber 13 is relatively narrow, which is conducive to the pins of the switch shaft 4 being distributed and arranged to avoid the rib air chamber 13. The rib air chamber 13 abuts against the PCB board 7, thus avoiding the problem of the pins of the switch shaft 4 piercing the airbag body 1 and causing damage.

[0032] The air chamber 13 has a supporting surface 131 at its top, which is parallel to the inclined surface 12. The air chamber 13 rests against the PCB board 7 via the supporting surface 131. Side walls 132 are provided on both sides of the supporting surface 131, which connect to the inclined surface 12 at a perpendicular or predetermined angle along both sides of the supporting surface 131, thus making the air chamber 13 narrower. The edges of the supporting surface 131 are provided with rounded chamfers 133 to prevent the edges of the supporting surface 131 from scraping and wearing against the PCB board 7, thereby further improving its service life.

[0033] This utility model relates to an adjustable air cushion vibration-damping mechanical keyboard structure. An airbag body 1 is installed inside the bottom shell 8, resting against the bottom of the PCB board 7. The airbag body 1 effectively reduces vibration during keystrokes, counteracts impact noise, enhances key rebound buoyancy, and improves keyboard comfort. Furthermore, users can adjust the air volume within the airbag cavity 11 according to their typing habits, thereby changing the buoyancy and allowing for adjustable key pressure, providing different keystroke feels and a unique user experience.

[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
