Abstract
Description
Technical Field
[0001] This application relates to a key structure, and particularly to a non-painted key structure. Background Art
[0002] The key structure in the prior art on a keyboard mainly includes a backlight, a lifting component, a keycap, a shielding layer, an unshielded layer, and a protective layer. The lifting component is disposed on the backlight, the keycap is disposed on the lifting component, the shielding layer and the unshielded layer are adjacently disposed on the surface of the keycap, and the protective layer covers the top surfaces of the shielding layer and the unshielded layer. Thus, when the backlight emits light, the unshielded layer can directly transmit the light to the corresponding protective layer of the unshielded layer to display to the user for identifying the control effect corresponding to the keycap. The shielding layer is formed by spraying a primer on the surface of the keycap, and after spraying the primer, a topcoat is sprayed on the top surface of the primer.
[0003] However, the key structure of the prior art forms the shielding layer on the keycap by spraying paint. Whether it is the primer or the topcoat, they are both chemical compounds. Therefore, the large-area chemical compound primer or topcoat not only causes environmental pollution but also increases the raw material cost of the primer or topcoat. Moreover, the keycap is largely shielded by the shielding layer, so that the overall key structure only displays light through the unshielded layer, providing a single visual sense to the user.
[0004] Therefore, there is indeed a need for the prior art to further provide a more improved solution. Summary of the Utility Model
[0005] In view of the above deficiencies of the prior art, the main purpose of this application is to provide a key structure. By covering part of the light-transmitting keycap, the uncovered area of the light-transmitting keycap can form a contrast color with the covered part, and it is not necessary to spray the primer or topcoat and can provide a large-area perspective area, so as to achieve the purposes of reducing environmental pollution, reducing costs, and providing a richer visual effect.
[0006] To achieve the above object, the main technical means adopted in this application is to make the key structure include:
[0007] A backlight module;
[0008] A lifting component disposed on the backlight module;
[0009] A light-transmitting keycap disposed on the lifting component and fixedly connected to the lifting component;
[0010] A first printing layer formed on part of the light-transmitting keycap; and
[0011] A protective layer formed on the first printing layer.
[0012] Preferably, the orthographic projection of the first printing layer on the surface of the light-transmitting keycap forms an orthographic projection area, and the orthographic projection area is smaller than the area of the surface of the light-transmitting keycap.
[0013] Preferably, the lifting assembly is a scissor structure.
[0014] Preferably, the lifting assembly is a mechanical key shaft.
[0015] Preferably, the protective layer is a transparent protective layer.
[0016] Preferably, the light-transmitting keycap comprises a light-transmitting material and titanium dioxide.
[0017] Preferably, the non-painted key structure further comprises:
[0018] A second printing layer formed on the surface of the light-transmitting keycap, the shape of the second printing layer matching the shape of the first printing layer, and the area of the second printing layer not exceeding the orthographic projection area.
[0019] Preferably, the ratio value of the titanium dioxide to the light-transmitting material is 10 / 10000.
[0020] Preferably, the light-transmitting material is polycarbonate or acrylonitrile-butadiene-styrene copolymer.
[0021] With the above structure, when the backlight module emits light, the light will penetrate the light-transmitting keycap, while the first printing layer cannot provide light penetration, so that a contrast is formed between the light-transmitting keycap and the first printing layer. Therefore, through the first printing layer, it is not necessary to spray a large area of primer or topcoat, and the first printing layer covers a part of the light-transmitting keycap, providing a large area of perspective blocks. In this way, environmental pollution is reduced, costs are lowered, and a richer visual effect is provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.
[0029] A cross-sectional schematic view of the first embodiment of the key structure 10 of the present application, as Figure 1 shown, the key structure 10 includes a backlight module 11, a lifting component 12, a light-transmitting keycap 13, a first printing layer 14, and a protective layer 15. The lifting component 12 is disposed on the backlight module 11, the lifting component 12 is disposed on the light-transmitting keycap 13, and the lifting component 12 is fixedly connected to the light-transmitting keycap 13. The first printing layer 14 is formed on a part of the light-transmitting keycap 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 printed on the light-transmitting keycap 13 in a printing manner.
[0030] By forming the first printing layer 14 on a part of the surface of the light-transmitting keycap 13, when the backlight module 11 emits light, a visual difference can be formed by the contrast between the light-transmitting keycap 13 and the first printing layer 14 to highlight the characters. Therefore, through the first printing layer 14, it is not necessary to spray primer or topcoat on a large area, and the first printing layer 14 is an opaque printing layer that partially covers the light-transmitting keycap 13, providing a large area of perspective blocks. In this way, the user can more clearly identify the control effects corresponding to the key structure 10, and the visual effect of the arrangement of the electronic components inside the key structure 10 can be seen through the light-transmitting keycap 13, enriching the user's visual senses.
[0031] In this embodiment, the first printing layer 14 covers a part of the surface of the light-transmitting keycap 13, that is, the first printing layer 14 projects orthogonally onto the surface of the light-transmitting keycap 13 to form an orthographic projection area, and the orthographic projection area is smaller than the area of the surface of the light-transmitting keycap 13.
[0032] In this embodiment, the first printing layer 14 is identification information, so that the user can select and control according to the identification information. The identification information is glyphs, symbols, numbers, etc. For example, the glyphs are English letters A-Z, the symbols are Chinese full stops, the numbers are 0-9, and the glyphs can also be Chinese characters.
[0033] To more clearly illustrate the actual use of the first embodiment of the present application, for example, taking the first printing layer 14 as the English letter A, as Figure 2 shown, the light-transmitting keycap 13 and the first printing layer 14 form a contrast for clearer identification.
[0034] In addition, a cross-sectional schematic diagram of the second embodiment of the key structure 10 of the present application is shown as Figure 3 shown. The key structure 10 further includes a second printing layer 16, and the second printing layer 16 is formed on the surface of the light-transmitting keycap 13. Specifically, the shape of the first printing layer 14 matches the shape of the second printing layer 16. The so-called matching means that the first printing layer 14 is formed on the inner and outer perimeters of the second printing layer 16, and only part of the boundary of the first printing layer 14 is closely attached to the boundary of the second printing layer 16. In other words, when the first printing layer 14 and the second printing layer 16 are both projected onto the same plane at the same time, only part of the boundaries between the first printing layer 14 and the second printing layer 16 overlap, and the other parts of the first printing layer 14 and the second printing layer 16 do not overlap. Moreover, the area of the second printing layer 16 does not exceed the orthographic projection area formed by the orthographic projection of the first printing layer 14 on the surface of the light-transmitting keycap 13.
[0035] In this embodiment, the second printing layer 16 is a light-transmitting printing layer or an opaque printing layer. When the second printing layer 16 is a light-transmitting printing layer, a more rich visual effect is presented by the first printing layer 14 formed on the perimeter of the second printing layer 16; in another aspect of this embodiment, when the second printing layer 16 is an opaque printing layer, it is easier for the user to identify by the first printing layer 14 formed on the perimeter of the second printing layer 16.
[0036] To more clearly illustrate the actual use of the second embodiment of the present application, for example, taking the first printing layer 14 as the English letter A, as Figure 4 shown, the second printing layer 16 and the first printing layer 14 are arranged correspondingly. That is to say, when the first printing layer 14 is the English letter A, the second printing layer 16 is also the English letter A, and moreover, the first printing layer 14 surrounds the perimeter of the second printing layer 16.
[0037] In the above embodiments, the lifting assembly 12 is a scissor structure or a mechanical key shaft.
[0038] In the above embodiments, the light-transmitting keycap 13 includes a light-transmitting material and titanium dioxide (TiO2), and the ratio value of the titanium dioxide to the light-transmitting material is 10 / 10,000. Through the ratio value of the light-transmitting material and the titanium dioxide, the light presented by the light-transmitting keycap 13 can be made softer. Specifically, the light-transmitting material is polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS).
[0039] In the above embodiments, the protective layer 15 is a transparent protective layer. Specifically, the protective layer 15 is formed by hardening with a photocuring agent to protect the first printing layer 14 and enable the printing color of the first printing layer 14 to be displayed through the transparent protective layer 15.
[0040] In the above embodiments, as Figure 5 shown, taking the lifting assembly 12 as a mechanical key shaft as an example, the key structure 10 is arranged on the mechanical key shaft, and the combination or action among the backlight module 11, the lifting assembly 12, and the light-transmitting keycap 13 can be actuated by the existing technologies in the art. Therefore, it will not be described in detail herein.
[0041] In summary, through the above key structure, when the backlight module emits light, the light source will penetrate the light-transmitting keycap, and the first printing layer cannot provide light penetration, so a contrast is formed between the light-transmitting keycap and the first printing layer. Therefore, through the first printing layer, it is not necessary to spray primer or topcoat over a large area, and the first printing layer partially covers the light-transmitting keycap to provide a large perspective area, thus reducing environmental pollution, lowering costs, and providing a richer visual effect.
[0042] It should be noted that in this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including that element.
[0043] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
