Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of keyboards, in particular to a ceramic key cap assembly. Background Art
[0002] At present, most of the keycaps of laptop computers are made of plastic. After long-term use, the keycaps gradually turn yellow due to oil deposition and plastic aging, and the symbols on the surface of the keycaps are blurred, which affects both the appearance and the use.
[0003] The crater structure is the most common membrane keyboard structure at present. The keycap and guide column of this structure are integrally formed, and the keycap can directly contact the rubber membrane. However, because the keycap contacts a convex and elastic rubber membrane, the keycap will shake greatly when pressing the key, affecting the typing feel. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a ceramic keycap assembly.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A ceramic keycap assembly includes a keycap shell and a connecting column. The keycap shell is made of ceramic material. The interior of the keycap shell is hollow and a limiting ring for embedding the connecting column is reserved on its inner top wall. The limiting ring is a circular ring. The top end of the connecting column is fixed to the inner side of the limiting ring by gluing and remains concentric with the limiting ring.
[0007] In a preferred technical solution, an inwardly protruding peripheral edge is arranged around the bottom opening edge of the key cap housing.
[0008] In a preferred technical solution, the keycap shell has a concentric circular slot at the center of the inner limiting ring, the top surface of the connecting column is provided with a raised ring adapted to the slot, and the inner side of the raised ring on the top surface of the connecting column is coated with glue.
[0009] In a preferred technical solution, the connecting column is a cylinder or a truncated cone, and a cross groove is formed on the bottom surface of the connecting column.
[0010] The beneficial effects of the utility model are:
[0011] The keycap assembly proposed in this solution solves the problem of large shaking of the crater structure keycaps, which affects the typing feel. The keycap shell and the connecting body are bonded and fixed to form an integrated structure. On the one hand, the ceramic keycaps have stable chemical properties, are not easy to fade, corrode and oxidize, and ensure normal use. On the other hand, they can reduce shaking during typing and improve the typing experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] In this embodiment, refer to Figure 1-4 A ceramic keycap assembly includes a keycap housing 1 and a connecting column 2. The keycap housing 1 is made of ceramic material. The ceramic material has stable chemical properties, is not easy to fade, corrode or oxidize, and ensures normal use.
[0019] The key cap housing 1 is hollow inside and a limit ring 4 for connecting the column 2 is reserved on the inner top wall thereof. An inwardly protruding peripheral edge 3 is arranged around the edge of the bottom opening of the key cap housing 1 .
[0020] The limiting ring 4 is a circular ring, and the key cap shell 1 has a concentric circular slot 5 at the center of the limiting ring 4 on its inner side. The top surface of the connecting column 2 is provided with a raised ring 6 that matches the slot 5, and the inner side of the raised ring 6 on the top surface of the connecting column 2 is coated with glue.
[0021] The connecting cylinder 2 is a cylindrical body or a truncated cone body, and a cross groove 7 is formed on the bottom surface of the connecting cylinder 2. The top of the connecting cylinder 2 is fixed to the inner side of the limiting ring 4 by pasting and is kept concentric with the limiting ring 4.
[0022] The connecting column 2 and the key cap shell 1 are fixedly connected with glue to form a whole, which can effectively reduce the shaking caused by typing and improve the typing experience.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
