Description

Technical Field

[0001] The utility model relates to the field of key caps, in particular to an injection-molded key cap with a decorative layer. Background Art

[0002] At present, the production method of keycaps is to spray paint on the surface of the keycaps after the injection molding of the keycap body, then carve characters or patterns on the paint surface, and then spray UV paint and harden after UV baking to achieve the decorative function; or print characters or patterns on the surface of the keycaps, and then print UV and harden after UV baking to achieve the decorative function. This production method uses spraying or printing technology, which will produce waste gas and waste residue in the process and is not environmentally friendly; at the same time, spraying or printing has multiple processes, the product needs to be turned over many times, and the long process flow leads to low efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to solve the technical problem described in the background technology, the utility model provides an injection-molded keycap with a decorative layer. The keycap is decorated by directly pasting the decorative layer on the keycap body and laser engraving a hollow area of ​​text or pattern on the decorative layer, thereby avoiding spraying or printing operations, protecting the environment, and improving processing efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An injection-molded keycap with a decorative layer comprises a keycap body and a decorative layer. The decorative layer is fixedly connected to the keycap body, a hollow area is provided on the decorative layer, and the decorative layer comprises a surface layer, an ink layer, and a connecting layer. The surface layer, the ink layer, and the connecting layer are sequentially stacked together from the outside to the inside, and the decorative layer is fixedly connected to the keycap body through the connecting layer.

[0006] Specifically, the surface layer is a UV layer.

[0007] Specifically, the connecting layer is a glue layer.

[0008] Specifically, the keycap body is made of transparent or translucent material.

[0009] The beneficial effect of the utility model is that the utility model provides an injection-molded keycap with a decorative layer. The keycap is decorated by directly pasting the decorative layer on the keycap body and laser engraving a hollow area of ​​text or pattern on the decorative layer, thereby avoiding spraying or printing operations, protecting the environment, and improving processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] Figure 1It is a structural schematic diagram of the utility model;

[0012] In the figure, 1. keycap body, 2. decorative layer, 21. surface layer, 22. ink layer, 23. connecting layer. DETAILED DESCRIPTION

[0013] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] As attached Figure 1 As shown, an injection molded keycap with a decorative layer includes a keycap body 1 and a decorative layer 2. The decorative layer 2 is fixedly connected to the keycap body 1, and a hollow area is provided on the decorative layer 2. The decorative layer 2 includes a surface layer 21, an ink layer 22, and a connecting layer 23. The surface layer 21, the ink layer 22, and the connecting layer 23 are sequentially stacked together from the outside to the inside, and the decorative layer 2 is fixedly connected to the keycap body 1 through the connecting layer 23.

[0016] The surface layer 21 is a UV layer. The surface layer 21 is formed into a hard UV layer by UV baking.

[0017] The connecting layer 23 is a glue layer.

[0018] The key cap body 1 is made of transparent or translucent material. When the light source in the keyboard emits light, it will pass through the transparent key cap body 1 and emit outward from the hollow area, so that it is easy to be recognized by the human eye.

[0019] The present application directly adheres the decorative layer 2 to the keycap body 1, and uses a laser engraving machine to carve a hollow area on the decorative layer 2 to form text or patterns, thereby eliminating the process of spraying or printing text patterns on the keycap, which not only avoids air pollution caused by spraying or printing, but also improves the processing efficiency of the keycap.

[0020] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
