Description

TECHNICAL FIELD

[0001] The utility model relates to the field of keyboard, especially a novel ceramic key cap and keyboard. BACKGROUND

[0002] The keyboard is an important input device for electronic devices, and the key cap is a small plastic cap-shaped component. The user's attention gradually shifts from the original practical performance to the appearance and art direction. Not only is the key cap practical, but also its texture and color are increasingly better. Ceramic products have both the texture of metal and the luster of glass mirror. The unique jewelry texture of the ceramic surface combined with its cold touch is more wear-resistant and skin-friendly than traditional metal and plastic key caps. Therefore, the key cap is entering the ceramic era. The ceramic key cap is assembled with the switch shaft. Since the ceramic hardness is large, it is easy to damage the switch shaft. However, the plastic key cap and the switch shaft are not easy to damage the switch shaft. Therefore, it is necessary to develop a new type of ceramic key cap. On June 7, 2024, the applicant applied for a patent with the patent number 2024213031026 and the patent name "ceramic key cap and keyboard". This technical solution has the problems of inaccurate positioning and complex forming. SUMMARY

[0003] To solve the above problems, the utility model provides a novel ceramic key cap and keyboard.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: the utility model relates to a novel ceramic key cap, which comprises a ceramic shell and a plastic inner core. The ceramic shell has a cavity with an opening facing downward. The inner surface of the ceramic shell is provided with a key core groove recessed inward. The plastic inner core is clamped into the key core groove through the opening.

[0005] Preferably, the plastic inner core comprises a base and a mounting column. The base has a first surface facing the key core groove and a second surface facing away from the key core groove. The inner surface of the ceramic shell is in close contact with the first surface, and the mounting column is arranged on the second surface.

[0006] Preferably, a plastic hot melt layer or an adhesive layer is arranged between the inner surface of the ceramic shell and the first surface.

[0007] To strengthen the bonding degree between the ceramic shell and the plastic inner core, the first surface is provided with a plurality of lines.

[0008] Preferably, the lines are grooves recessed downward on the top surface of the base and extending along a straight line.

[0009] Preferably, the plurality of grooves are arranged along a straight line, and the arrangement direction of the plurality of grooves is parallel or inclined to the width direction of the ceramic shell. In this way, a twill pattern effect can be presented on the surface of the keycap. The bonding area between the ceramic shell and the plastic inner core is effectively increased, so that the ceramic shell is more firmly bonded together.

[0010] Preferably, the outer edge of the key core groove is a groove edge, and the second surface is flush with the groove edge.

[0011] Preferably, the ceramic shell comprises a shell key top and a shell key skirt, and the shell key skirt is formed by extending downward in a vertical or predetermined angle direction from the contour of the shell key top.

[0012] Preferably, the area of the abutment is slightly larger than the area of the key core groove.

[0013] A keyboard comprising the ceramic keycap.

[0014] The beneficial effects of the present application are that the present application relates to a novel ceramic keycap, which is different from the early scheme of the applicant in the structure of the plastic inner core and the structure of the combination of the plastic inner core and the ceramic shell. A key core groove is arranged in the ceramic shell, and the abutment of the plastic inner core extends into the key core groove, so that the dimensional accuracy can be accurately controlled, assembly is easier, and the problem of different sizes of ceramic keycaps can be effectively solved, which can greatly reduce the scrap rate of ceramic keycaps.
