Description

Technical Field

[0001] This utility model relates to the field of keyboard dustproof technology, specifically a blade keyboard with dustproof function. Background Technology

[0002] Scissor-switch keyboards typically refer to keyboards that use a scissor-switch mechanism, such as laptop keyboards and ultra-thin office keyboards. Due to their lightweight and portability, short key travel, and sensitive triggering, they are widely used in office, automotive, and embedded device scenarios.

[0003] Scissor-switch keyboards are widely used in office environments. After a period of use, dust tends to accumulate in certain areas of the keyboard. While dustproof devices on scissor-switch keyboards typically protect the keyboard surface from dust, the USB ports on the side of the keyboard are often exposed to the desktop environment for extended periods. The mechanical gap between the USB port and the plug becomes a major entry point for dust, easily accumulating dust, hair, debris, and other foreign objects. Dust particles can enter the USB port through vibration or airflow, affecting the device's heat dissipation and reducing its lifespan.

[0004] To address this issue, we designed a dustproof keyboard with blade feet. Utility Model Content

[0005] The purpose of this invention is to provide a blade-type keyboard with dustproof function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a dustproof keyboard with blade feet, including a keyboard body and a connecting cable disposed outside the keyboard body. One end of the connecting cable is connected to a plug body. The keyboard body has a USB interface. The plug body and the USB interface are compatible. A rubber pad is disposed inside the USB interface. One end of the plug body near the connecting cable is connected to a housing. The housing is provided with an arc-shaped scraper blade, which is made of a flexible material.

[0007] Furthermore, the outer wall of the keyboard body is connected to a slide rail, a slide table is slidably connected on the slide rail, a dustproof baffle is connected to the bottom surface of the slide table, and the outer wall of the dustproof baffle is in contact with the outer wall of the keyboard body.

[0008] Furthermore, a dust collection strip is provided on the outer surface of the keyboard body, and an iron sheet is connected to the outer wall of the dust collection strip. A magnet is provided inside the keyboard body, and the iron sheet is magnetically connected to the magnet.

[0009] Furthermore, a sponge pad is connected to the outer wall of the outer casing, and the arc-shaped scraper is disposed on the sponge pad.

[0010] Furthermore, the keyboard body has a groove, and a dustproof film is embedded in the groove.

[0011] Furthermore, the keyboard body is also provided with a keycap shell, one end of which is set on a dustproof film.

[0012] Furthermore, a friction pad is provided on the slide.

[0013] Furthermore, the surfaces of the slide and the dustproof baffle are both provided with a wear-resistant coating.

[0014] The beneficial effects of this utility model are: during the plug insertion and removal process, the arc-shaped scraper can scrape off dust that may be attached to the edge and inside of the USB interface, and the sponge pad further absorbs the scraped dust, preventing dust from flying back into the USB interface or other components, reducing the accumulation of dust at the USB interface, and improving the service life of the device.

[0015] The beneficial effects of this utility model are: the slide rail on the outer wall of the keyboard body cooperates with the slide table to drive the dustproof baffle to slide. When the keyboard is not in use, the slide table is pushed to make the dustproof baffle cover the key parts of the keyboard body to prevent dust from entering; the friction pad on the slide table can increase the stability of the slide table positioning, prevent the dustproof baffle from sliding accidentally, and further improve the dustproof effect at the USB interface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a dustproof keyboard with blade feet, including a keyboard body 1 and a connecting cable 4 disposed outside the keyboard body 1. One end of the connecting cable 4 is connected to a plug body 5. The keyboard body 1 has a USB interface 6. The plug body 5 and the USB interface 6 are compatible. When the plug body 5 is inserted into the USB interface 6, the elastic design of the rubber pad 7 allows it to adapt to the insertion and removal action of the plug body 5, while maintaining effective sealing of the gap, preventing dust from entering the internal circuit through the gap between the USB interface 6 and the plug body 5. A rubber pad 7 is disposed inside the USB interface 6. The end of the plug body 5 near the connecting cable 4 is connected to a housing 13. The body 13 is provided with an arc-shaped scraper 15, which is made of flexible material, namely silicone. A sponge pad 14 is connected to the outer wall of the outer shell 13. During the insertion of the plug body 5, the arc-shaped scraper 15 presses against the edge of the USB interface 6 through the pressure generated by the elastic deformation, and completes the dust removal action on the edge and inner wall of the USB interface 6 before the plug body 5 is fully inserted. After the dust particles scraped off by the arc-shaped scraper 15 leave the surface of the USB interface 6, some fall directly into the pore structure of the sponge pad 14, while the other part of the flying dust is attracted by the electrostatic of the surface of the sponge pad 14 to prevent it from re-entering the USB interface 6. The arc-shaped scraper 15 is set on the sponge pad 14.

[0023] In practice, a rubber pad 7 is provided inside the USB interface 6. When the plug body 5 is inserted into the USB interface 6, the outer shell 13 is located on the outer edge of the USB interface 6. The arc-shaped scraper 15 on the outer shell 13 connected to the plug body 5 is made of flexible material. During the insertion and removal of the plug body 5, the arc-shaped scraper 15 can scrape off dust that may be attached to the edge and inside of the USB interface 6. The sponge pad 14 further absorbs the scraped dust, preventing dust from flying back into the USB interface 6 or other components, reducing the accumulation of dust at the USB interface 6, and improving the service life of the device.

[0024] See Figure 3As shown, the outer wall of the keyboard body 1 is connected to a slide rail 8, and a slide table 10 is slidably connected to the slide rail 8. A dustproof baffle 12 is connected to the bottom surface of the slide table 10. When the keyboard is idle, the user only needs to gently push the slide table 10, and the slide table 10 can move smoothly along the slide rail 8, thereby driving the dustproof baffle 12 connected to it to slide synchronously. The outer wall of the dustproof baffle 12 is in contact with the outer wall of the keyboard body 1. A friction pad 11 is provided on the slide table 10. When the slide table 10 moves to the designated position, a large friction force is generated between the friction pad 11 and the keyboard body 1 or other contact surfaces, preventing the dustproof baffle 12 from accidentally sliding due to minor external collisions, vibrations, etc., and further enhancing the dustproof effect of parts such as the USB interface 6. The surfaces of the slide table 10 and the dustproof baffle 12 are both provided with a wear-resistant coating, which is epoxy resin, to reduce the wear of the device.

[0025] In practice, the slide rail 8 on the outer wall of the keyboard body 1 cooperates with the slide table 10 to drive the dustproof baffle 12 to slide. When the keyboard body 1 is not in use, the slide table 10 is pushed so that the dustproof baffle 12 covers the key parts of the keyboard body 1 to prevent dust from entering. The friction pad 11 on the slide table 10 can increase the stability of the positioning of the slide table 10, prevent the dustproof baffle 12 from sliding accidentally, and further improve the dustproof effect at the USB interface 6.

[0026] See Figure 2 The keyboard body 1 also has a dust collection strip 9 on its exterior. The dust collection strip 9 is located below the USB port 6. When the curved scraper 15 scrapes the inside of the USB port 6, some of the dust will fall into the dust collection strip 9. The outer wall of the dust collection strip 9 is connected to an iron plate. There is a magnet inside the keyboard body 1. The iron plate is magnetically connected to the magnet. The dust collection strip 9 can be removed by magnetic means, making it easy to clean the dust collection strip 9.

[0027] See Figure 1 The keyboard body 1 has a groove, in which a dustproof film 3 is embedded. The depth of the groove is matched with the thickness of the dustproof film 3. The surface of the dustproof film 3 is also coated with a hydrophobic coating, which can effectively prevent liquid penetration. The keyboard body 1 is also provided with a keycap shell 2. One end of the keycap shell 2 is placed on the dustproof film 3 to reduce dust from entering the interior of the keyboard body 1 from the surface of the keycap shell 2.

[0028] Working principle: A rubber pad 7 is provided inside the USB interface 6. When the plug body 5 is inserted into the USB interface 6, the outer shell 13 is located on the outer edge of the USB interface 6. The arc-shaped scraper 15 on the outer shell 13 connected to the plug body 5 is made of flexible material. During the insertion and removal of the plug body 5, the arc-shaped scraper 15 can scrape off dust that may be attached to the edge and inside of the USB interface 6. The sponge pad 14 further absorbs the scraped dust, preventing dust from flying back into the USB interface 6 or other components, reducing the accumulation of dust at the USB interface 6, and improving the service life of the device. The slide rail 8 on the outer wall of the keyboard body 1 cooperates with the slide table 10 to drive the dustproof baffle 12 to slide. When the keyboard is not in use, the slide table 10 is pushed so that the dustproof baffle 12 covers the key parts of the keyboard body 1, blocking dust from entering. The friction pad 11 on the slide table 10 can increase the stability of the slide table 10's positioning, prevent the dustproof baffle 12 from sliding accidentally, and further improve the dustproof effect at the USB interface 6.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
