However, in the key structure of the prior art, the shielding layer is formed on the key cap by spraying paint, and no matter the primer or the top coat is of a chemical composition, so that the primer or the top coat of the large-area chemical composition can increase the raw material cost of the primer or the top coat in addition to causing environmental pollution, and the key cap is shielded by the shielding layer to a large extent, so that the whole key structure only displays light through the non-shielding layer, and a single visual sense of a user is provided.

Thus, the prior art does need to further provide the necessity of more improved solutions.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

As shown in fig. 1, the key structure 10 of the first embodiment of the present application includes a backlight module 11, a lifting assembly 12, a transparent key cap 13, a first printed layer 14 and a protective layer 15. The lifting assembly 12 is disposed on the backlight module 11, the lifting assembly 12 is disposed on the transparent key cap 13, the lifting assembly 12 is fixedly connected with the transparent key cap 13, the first printing layer 14 is formed on a part of the transparent key cap 13, and the protective layer 15 is formed on the first printing layer 14. Specifically, the first printing layer 14 is an opaque printing layer, and is printed on the transparent key cap 13 in a printing manner.

By forming the first printed layer 14 on a part of the surface of the light-transmitting key cap 13, when the backlight module 11 emits a light source, a visual difference may be formed by the contrast between the light-transmitting key cap 13 and the first printed layer 14 to highlight a character. Therefore, the first printing layer 14 does not need a large-area spraying primer or top-coat, and the first printing layer 14 is an opaque printing layer, which partially covers the transparent key cap 13, so as to provide a large-area perspective area, so that the user can more clearly identify the control effect corresponding to the key structure 10, and the visual effect of the arrangement of the electronic components in the key structure 10 can be seen through the transparent key cap 13, thereby enriching the visual sense of the user.

In this embodiment, the first printed layer 14 is a surface of the light-transmitting key cap 13 that covers a portion, that is, the first printed layer 14 is orthographically projected on the surface of the light-transmitting key cap 13 to form an orthographic projection area, and the orthographic projection area is smaller than the area of the surface of the light-transmitting key cap 13.

In this embodiment, the first printing layer 14 is identification information, so as to provide a user with corresponding selection and control according to the identification information, wherein the identification information is a font, a symbol, or a number, for example, the font is english letters a-Z, the symbol is a period of chinese, the number is 0-9, and the font may be chinese.

For more clearly describing the practical use of the first embodiment of the present application, for example, the first printed layer 14 is an english letter a, as shown in fig. 2, the transparent key cap 13 is compared with the first printed layer 14 for more clear identification.

In addition, as shown in fig. 3, the key structure 10 further includes a second printed layer 16, and the second printed layer 16 is formed on the surface of the transparent key cap 13. Specifically, the shape of the first printed layer 14 is matched with the shape of the second printed layer 16, where the first printed layer 14 is formed on the inner periphery and the outer periphery of the second printed layer 16, and a part of the boundary of the first printed layer 14 is closely attached to the boundary of the second printed layer 16 only, in other words, when the first printed layer 14 and the second printed layer 16 are both projected on the same plane, only a part of the boundary between the first printed layer 14 and the second printed layer 16 overlaps, and the other part of the first printed layer 14 is not overlapped with the other part of the second printed layer 16, and the area of the second printed layer 16 does not exceed the orthographic projection area formed by orthographic projection of the first printed layer 14 on the surface of the light-transmitting key cap 13.

In this embodiment, the second printed layer 16 is a transparent printed layer or a non-transparent printed layer, when the second printed layer 16 is a transparent printed layer, the first printed layer 14 is formed on the periphery of the second printed layer 16, so as to present a richer visual effect, and in another aspect of this embodiment, when the second printed layer 16 is a non-transparent printed layer, the first printed layer 14 is formed on the periphery of the second printed layer 16, so that the user can easily identify the visual effect.

For more clearly describing the practical use of the second embodiment of the present application, for example, taking the first printing layer 14 as english letter a as an example, as shown in fig. 4, the second printing layer 16 is disposed corresponding to the first printing layer 14, that is, when the first printing layer 14 is english letter a, the second printing layer 16 is english letter a, and the first printing layer 14 surrounds the periphery of the second printing layer 16.

In the above embodiments, the lifting assembly 12 is a scissor foot structure or a mechanical key shaft.

In the above embodiment, the transparent key cap 13 includes a transparent material and titanium dioxide (TiO ₂), and the ratio of the titanium dioxide to the transparent material is 10/10000, so that the light rays displayed by the transparent key cap 13 can be softer by the ratio of the transparent material to the titanium dioxide. Specifically, the light-transmitting material is Polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene, ABS).

In the above embodiment, the protective layer 15 is a transparent protective layer. Specifically, the protective layer 15 is formed by curing with a photo-curing agent to protect the first printing layer 14, and the printing color of the first printing layer 14 can be displayed by the protective layer 15 being the transparent protective layer.

In the above embodiment, as shown in fig. 5, taking the lifting assembly 12 as an example of a mechanical key shaft, the key structure 10 is disposed on the mechanical key shaft, and the combination or the action among the backlight module 11, the lifting assembly 12 and the transparent key cap 13 can be performed by adopting the prior art, so that the description is omitted.

In summary, through the above-mentioned key structure, when the backlight module emits the light source, the light source will penetrate the transparent keycap, and the first printed layer cannot provide the light source to penetrate, so that a contrast is formed between the transparent keycap and the first printed layer, and therefore, the first printed layer does not need a large area of splash primer or finish paint, and the first printed layer partially covers the transparent keycap to provide a large area of perspective blocks, thereby achieving the purposes of reducing environmental pollution, reducing cost and providing richer visual effects.
