[0002] With the continuous development of computer technology, keyboards, as an important input device for computers, are receiving more and more attention for their performance and quality. Shaftless keyboards usually refer to membrane keyboards. This type of keyboard has no mechanical axis, and its key triggering principle is achieved through the rubber membrane or other elastic materials under the keycaps.
[0003] After searching, a Chinese patent with announcement number CN220340671U discloses a computer keyboard. It solves the problem that different people use keyboard keys at different frequencies, such as accountants and other personnel who need to input numbers frequently, and gamers often use up, down, left, and right keys, which are inconvenient for different groups of people to use. By dividing the keyboard body into different areas, the main applicable functions of different areas are different, the application range is wide, and it is more convenient and fast; the palm rest is used to place the palm and wrist, etc., to reduce hand fatigue.
[0004] During the use of this computer keyboard, the keyboard shaft structure is prone to accumulate dust, causing key failure; the waterproof performance is also relatively weak, and once water enters, the circuit board may be damaged; at the same time, the keys of the mechanical keyboard are loud, which will limit its use in some environments that require quietness. Utility Model Content

[0014] Technical effects and advantages of this utility model:
[0015] 1. By setting up a shaftless noise reduction mechanism and adopting a shaftless keyboard design, the keystroke feel is lighter. The lack of shafts in traditional mechanical keyboards reduces the resistance generated by the keys. The use of electrostatic induction technology also makes the keystroke sound softer. The shaftless design reduces the channels for dust to enter. Combined with the blocking effect of the sealing rubber ring, it can effectively prevent dust from invading the keyboard, keeping the keyboard clean and reducing key failures caused by dust accumulation. It effectively prevents moisture from entering the keyboard, greatly reducing the risk of damage to the circuit board due to accidental water immersion and extending the service life of the keyboard.
[0016] 2. The movable connection between the positioning column and the mounting slot and the fixing method of the mounting bolts make the installation and disassembly of the keyboard very simple and quick. The user can easily separate the first plate and the second plate for convenient cleaning and maintenance, maintaining the good performance of the keyboard. It combines multiple advantages such as waterproof, dustproof, noise reduction and easy cleaning and maintenance, meeting the needs of users in different usage scenarios, and has high practicality and cost-effectiveness.

[0027] As attached Figure 2 、 3 As shown, the sealing rubber ring 10 is made of silicone material, and the edges of the upper circuit board 7 and the lower circuit board 9 are coated with a waterproof rubber layer to further improve the waterproof and dustproof effects.
[0028] As attached Figure 2 、 4 As shown, the noise reduction cotton interlayer 4 is made of a multi-layer composite sound-absorbing cotton material, and the positioning plate 5 is made of rubber material, which reduces vibration during use and improves the noise reduction effect.
[0029] Working principle of the utility model: The utility model provides a waterproof, dustproof and noise-reducing computer keyboard. During use, the silicone sealing rubber ring 10 adhered to the inner wall of the first plate 1 and the second plate 2 forms the first waterproof defense line after the keyboard is assembled, preventing moisture from entering the keyboard from the gap between the plates. The waterproof adhesive layer coated on the edge of the upper circuit board 7 and the lower circuit board 9 protects the circuit board and prevents moisture from contacting the circuit board components, ensuring that the circuit board can maintain normal operation in the event of accidental water immersion. The design of the membrane key layer 6, the upper circuit board 7 and the lower circuit board 9 is adopted. The shaftless design is completed to prevent dust from entering through the gaps in the keycap 3. The sealing rubber ring 10 can also prevent dust from entering the interior of the board to a certain extent. A noise reduction cotton interlayer 4 made of a multi-layer composite sound-absorbing cotton material is arranged at the bottom of the first board 1. When the keycap 3 is pressed, the vibration and sound generated will be absorbed by the noise reduction cotton interlayer 4, reducing the spread of noise. The positioning plate 5 made of rubber material is located at the bottom of the noise reduction cotton interlayer 4. On the one hand, it provides support and positioning for the membrane key layer 6, etc. On the other hand, the rubber material has a certain elasticity, which can further buffer the impact force when the keycap 3 is pressed, reducing vibration noise;
[0030] During installation, align the positioning post 13 at the bottom of the first plate body 1 with the mounting groove 12 on the top surface of the second plate body 2, so that the positioning post 13 is movably engaged with the mounting groove 12 to preliminarily fix the position of the first plate body 1 and the second plate body 2. Then, screw the mounting bolt 17 into the threaded groove 14 on the bottom surface of the positioning post 13 and the threaded hole 16 on the top surface of the inner wall of the groove 15 to further fix the two plates. The fixing knob 18 is located inside the groove 15, and the depth of the groove 15 is greater than the height of the fixing knob 18, ensuring that the bottom of the keyboard is flat. You only need to unscrew the mounting bolt 17 to separate the first plate body 1 and the second plate body 2, which is convenient for cleaning and maintenance of the keyboard.
[0031] Finally, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed in this utility model are intended to be covered by the claims of this utility model.
