Description

Technical Field

[0001] This utility model belongs to the field of keyboard technology, specifically a magnetic dustproof mechanical keyboard. Background Technology

[0002] Mechanical keyboards are widely used in office, gaming and other scenarios due to their excellent typing feel and durability.

[0003] However, traditional mechanical keyboards have a significant problem: dust and debris easily accumulate inside the keyboard, which not only affects the lifespan of the keyboard but may also cause key malfunctions and circuit failures. To solve this problem, some keyboards with dust covers have appeared on the market, but these dust covers usually use clips or manual fixing methods, which are cumbersome to disassemble and install, resulting in a poor user experience. Therefore, we propose a magnetic dustproof mechanical keyboard. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a magnetic dustproof mechanical keyboard, comprising a base, a PCB board, mechanical switches, and keycaps. The base has a telescopic cavity on its side wall, and a dustproof cover scroll mechanism is built into the telescopic cavity. The scroll mechanism includes a dustproof cover, which is made of flexible composite material. One end of the dustproof cover is fixed to the scroll, and the other end is provided with a magnetic strip. A flexible magnetic array is embedded along the upper edge of the base. The thickness of the flexible magnetic array is ≤0.5mm. The magnetic strip and the flexible magnetic array attract each other, so that the dustproof cover fits tightly against the keyboard surface.

[0005] Preferably, the edge of the dust cover is coated with a self-healing nano-sealing adhesive layer, the adhesive layer being composed of a siloxane-polyurethane copolymer, which is used to enhance the sealing performance of the dust cover.

[0006] Preferably, the reel mechanism includes a spiral spring and a ratchet lock, which automatically locks when the dust cover is stretched. The dust cover can be automatically retracted after the release button is pressed, which is used to unlock the ratchet lock and allow the dust cover to be automatically retracted under the action of the spiral spring.

[0007] Preferably, the flexible magnetic array is made of neodymium iron boron powder and flexible silicone composite pressing, with a surface magnetic induction intensity ≥80mT, which has high magnetic induction performance and ensures sufficient adsorption force between the magnetic strip and the magnetic array.

[0008] Preferably, the dust cover, when stretched, can cover the keyboard surface and the gaps between the keycaps, and is used to clean dust from the keyboard surface and the gaps between the keycaps.

[0009] Preferably, the dust cover is fully retracted into the telescopic cavity when in the storage state, without affecting the normal use of the keyboard.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] During normal keyboard use, the dust cover is retracted, fully housed in the telescopic cavity on the side wall of the base, without affecting keyboard operation or appearance. The flexible magnetic array is embedded along the upper edge of the base, ready to attract the magnetic strip on the dust cover. When the keyboard needs to be used, the user manually pulls the dust cover out of the telescopic cavity. The magnetic strip at one end of the dust cover attracts the flexible magnetic array along the upper edge of the base, causing the dust cover to fit tightly against the keyboard surface, forming a sealing layer to prevent dust from entering. The self-healing nano-sealing adhesive layer at the edge of the dust cover fills tiny gaps under magnetic pressure, further enhancing the sealing effect. When cleaning the keyboard is required, the user then... The dust cover is manually stretched to cover the keyboard surface and keycap gaps. It can then be pulled out from the side via the roller. Users can manually wipe the dust cover or use other cleaning tools to clean the dust on and inside the keyboard by utilizing its covering effect. The dust cover's electrostatic adsorption properties help attract dust particles, improving the cleaning effect. After cleaning, the user presses the release key, the ratchet lock unlocks, the scroll spring releases energy, and drives the roller to rotate, automatically retracting the dust cover into the telescopic cavity, restoring it to its stored state. This achieves the dual function of dust prevention and cleaning. At the same time, the use of magnetic attraction, self-healing sealing, and automatic recycling principles improves the keyboard's ease of use and maintenance efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figure 1The present invention includes a base 1, a PCB board 2, a mechanical switch 3, and keycaps 4. The side wall of the base 1 is provided with a telescopic cavity 105. The telescopic cavity 105 contains a dust cover scroll mechanism 6. The scroll mechanism 6 includes a dust cover 5, which is made of flexible composite material. One end of the dust cover 5 is fixed to the scroll 601, and the other end is provided with a magnetic strip 501. A flexible magnetic array 106 is embedded along the upper edge of the base 1. The thickness of the flexible magnetic array 106 is ≤0.5mm. The magnetic strip 501 and the flexible magnetic array 106 attract each other, so that the dust cover 5 is tightly attached to the keyboard surface.

[0017] The edges of the dust cover 5 are coated with a self-healing nano-sealing adhesive layer, which is composed of siloxane-polyurethane copolymer to enhance the sealing performance of the dust cover.

[0018] The reel mechanism 6 includes a spiral spring and a ratchet lock. It automatically locks when the dust cover 5 is stretched. The dust cover 5 can be automatically retracted after the release key 602 is pressed, which is used to unlock the ratchet lock and allow the dust cover to be automatically retracted under the action of the spiral spring.

[0019] The flexible magnetic array 106 is made of neodymium iron boron powder and flexible silicone composite pressing. The surface magnetic induction intensity is ≥80mT, which has high magnetic induction performance and ensures that there is sufficient adsorption force between the magnetic strip and the magnetic array.

[0020] When stretched, the dust cover 5 can cover the keyboard surface and the gaps between the keycaps 4, and is used to clean the dust from the keyboard surface and the gaps between the keycaps.

[0021] When the dust cover 5 is in its stored state, it is completely retracted into the telescopic cavity 105, without affecting the normal use of the keyboard.

[0022] Working Principle: During normal keyboard use, the dust cover 5 is in a retracted state, completely housed within the telescopic cavity 105 on the side wall of the base 1, without affecting the keyboard's operation or appearance. The flexible magnetic array 106 is embedded in the upper edge of the base 1, ready to be attracted to the magnetic strip 501 on the dust cover. When the keyboard needs to be used, the user manually pulls the dust cover 5 out of the telescopic cavity 105. The magnetic strip 501 at one end of the dust cover 5 attracts the flexible magnetic array 106 on the upper edge of the base 1, causing the dust cover to fit tightly against the keyboard surface, forming a sealing layer to prevent dust from entering the keyboard. The self-healing nano-sealing adhesive layer at the edge of the dust cover fills the tiny gaps under magnetic pressure, further enhancing the sealing effect. When cleaning the keyboard, the user manually stretches the dust cover 5 again to cover the keyboard surface and keycap gaps, and pulls the dust cover 6 out from the side via the scroll 6. The user can manually wipe the dust cover or use other cleaning tools to clean the dust on and inside the keyboard by utilizing the covering effect of the dust cover. The electrostatic adsorption performance of the dust cover helps to attract dust particles and improve the cleaning effect. After cleaning, the user presses the release key 602, the ratchet lock unlocks, the scroll spring releases energy, drives the scroll 601 to rotate, and automatically rolls the dust cover back into the telescopic cavity 105, restoring it to the storage state. This achieves the dual function of dust prevention and cleaning. At the same time, by using the principles of magnetic attraction, self-healing sealing and automatic recycling, the convenience of using the keyboard and the efficiency of maintenance are improved.
