Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a ceramic key cap and a keyboard. Background Art

[0002] Keyboards are extremely important input devices for electronic devices. Keycaps are small plastic cap-shaped parts. Users' attention has gradually shifted from the original practical performance to the direction of appearance and aesthetics. They not only require keycaps to be practical, but also require them to have better texture and brighter colors. Ceramic products have both the texture of metal and the luster of glass mirrors. The cold touch of the ceramic surface is matched with its unique jewelry texture. It is more wear-resistant and skin-friendly than traditional metal and plastic keycaps, so it is becoming more and more popular. Keycaps are about to enter the ceramic era. Ceramic keycaps are assembled with switch shafts. Due to the high hardness of ceramics, the switch shafts are easily damaged. At present, the assembly of plastic keycaps with switch shafts is not easy to damage the switch shafts. Therefore, it is very necessary to develop a new type of ceramic keycaps.

[0022] See also Figure 1-5As shown, the utility model relates to a ceramic keycap, which is an important component of a keyboard, and comprises a plastic inner shell 1 and a ceramic outer shell 2. The shape of the ceramic outer shell 2 is larger than that of the plastic inner shell 1. The ceramic outer shell 2 wraps the plastic inner shell 1 and is formed integrally therewith.

[0023] Furthermore, in this embodiment, the plastic inner shell 1 includes an inner shell key top 11 and an inner shell key skirt 12, and the inner shell key skirt 12 is formed by extending downward in a direction perpendicular to or at a predetermined angle to the outline of the inner shell key top 11. In this embodiment, the outer shape of the inner shell key top 11 is a quadrilateral, and the outline of the inner shell key top 11 is provided with an inner shell chamfer 111. Among them, the interior of the plastic inner shell 1 is provided with a mounting column 13, and the mounting column 13 is arranged at the lower end of the inner shell key top 11, and the end of the mounting column 13 is provided with a mounting groove 131 for assembling the switch shaft.

[0024] Furthermore, the inner surface of the ceramic shell 2 is attached to the outer surface of the plastic inner shell 1. In this embodiment, the ceramic shell 2 includes a shell key top 21 and a shell key skirt 22. The shell key skirt 22 is formed by extending downward in a vertical or predetermined angle direction with the outline of the shell key top 21. Among them, the shell key top 21 is provided with a curved surface 211 that fits the curvature of the finger. The curved surface 211 is recessed toward the center of the shell key top 21 by a certain curvature. The outline of the shell key top 21 is provided with a shell chamfer 212. In addition, in this embodiment, the shell key top 21 is provided with a key character 213, which is convenient for users to find the corresponding character for typing operation.

[0025] Since the ceramic outer shell 2 and the plastic inner shell 1 are made of different materials, the present invention uses a chemical adhesive to bond the ceramic outer shell 2 and the plastic inner shell 1 together so that the ceramic outer shell 2 and the plastic inner shell 1 are integrated. The chemical adhesive may be, for example, epoxy resin, silicone, etc. When the ceramic outer shell 2 and the plastic inner shell 1 are assembled and formed into one piece, the ceramic outer shell 2 covers the plastic inner shell 1 from the Y-axis direction, completely wrapping the outer surface of the plastic inner shell 1, and the plastic inner shell 1 is supported inside the ceramic outer shell 2.

[0026] In addition to bonding, the ceramic shell 2 and the plastic inner shell 1 can also be fixed together mechanically, such as a snap-fit ​​structure, or a hot melt layer can be formed on the surface of the plastic inner shell 1. The hot melt layer is a partial melt of the surface of the plastic inner shell 1, which is combined with the inner surface of the ceramic shell 2 and forms a strong connection after cooling. In the manufacturing process, the ceramic shell 2 can be fixed in a mold, and then the molten plastic material is injected into the mold. After cooling, the plastic inner shell 1 will be tightly combined with the ceramic shell 2. A layer of plastic coating is applied to the inner surface of the ceramic shell 2, and it is combined with the plastic inner shell 1 through the plastic coating.

[0027] The utility model relates to a ceramic keycap, which has a ceramic shell 2. Compared with a conventional keycap shell, the ceramic shell 2 of the utility model adopts a ceramic material. The ceramic shell 2 has higher hardness, better wear resistance and corrosion resistance, is not easily damaged, and is not easily affected by fading, sweat or grease corrosion. After long-term use, it can still maintain a new appearance.

[0028] At the same time, the ceramic keycaps of the utility model also have good thermal conductivity, which helps to reduce the temperature of the keyboard and make the touch feel cool and smooth. At the same time, the ceramic shell 2 can provide a deep sound and a solid typing feeling when typing, and the tapping sound is also crisp and pleasant, giving users a different tapping experience.

[0029] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
