Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a transparent key cap with a refractive structure. Background Art

[0002] The existing RGB transparent mechanical keyboard designs on the market often have transparent keycap designs with solid-color transparent keycaps with no texture on the inner wall, full frosted keycaps or semi-frosted keycaps. When such designs interact with the RGB luminous components of the key shaft, the transparent keycaps with no texture on the inner wall cannot produce better lighting effects through refraction, and from the user's perspective, a better human-computer lighting interaction experience cannot be obtained. Full frosted keyboards or semi-frosted keyboards cannot fully show the amount and refraction form of RGB light, thereby reducing the interactive experience with RGB light during use. Utility Model Content

[0003] The main purpose of the utility model is to propose a transparent keycap with a refractive structure, aiming to improve the structure of the keycap, so as to produce better light refraction between the keycap and the lighting components in the mechanical axis, and to assist in quick identification and positioning when the user is in a low-light environment, such as school dormitories, Internet cafes, study rooms and shared bedrooms.

[0004] To achieve the above-mentioned purpose, the utility model proposes a transparent keycap with a refractive structure, including a keycap made of transparent material or translucent material, wherein the keycap is a cavity with an opening at the lower end, and the inner peripheral wall of the cavity is provided with a protruding refractive structure, wherein the refractive structure is a refractive bump or a refractive texture, and when the light source of the keyboard body is illuminated, the refractive bump can transmit the light through the refractive bump to the transparent part or translucent part of the keycap.

[0005] The technical solution of the utility model adds a refractive structure in the inner wall of the transparent keycap, so that the refractive structure can illuminate the RGB lighting effect in the key shaft to the inner wall of the keyboard body and realize multiple refractions of the light. For low-brightness RGB lighting, the light is more uniform. For a rechargeable keyboard, it is more energy-efficient. Moreover, according to the actual design, the part of the keycap that does not require a light source can be coated with a shading structure so that the light source is only transmitted to the transparent part or the opaque part, thereby improving the recognition and comfort of the keycap and improving the aesthetics of the keyboard.

[0010] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0011] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0012] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0013] like Figures 1 to 3 As shown, a transparent keycap with a refractive structure comprises a keycap 1 made of a transparent material or a translucent material, wherein the keycap 1 is a cavity with an opening at the lower end, and the inner peripheral wall of the cavity is provided with a protruding refractive structure 11, wherein the refractive structure 11 is a refractive bump or a refractive texture, and when the light source of the keyboard body emits light, the refractive bump can transmit the light to the transparent part or the translucent part of the keycap 1 through the refractive bump.

[0014] A refractive structure 11 is added to the inner wall of the transparent keycap, so that the refractive structure 11 can illuminate the RGB lighting effect in the key shaft onto the inner wall of the keyboard body and realize multiple refractions of the light. For low-brightness RGB lighting, the light is more uniform. For a charging keyboard, it is more energy-efficient. Moreover, according to the actual design, the part of the keycap 1 that does not require a light source can be coated with a shading structure so that the light source is only transmitted to the transparent part or the opaque part, thereby improving the recognition and comfort of the keycap and improving the aesthetics of the keyboard.

[0015] Specifically, the refractive protrusion is a quadrangular pyramid 12 which gradually descends from the middle to the surrounding areas, and the edges of adjacent quadrangular pyramids 12 fit together, so that the light is refracted through the four faces, and then the light is irradiated on the transparent part or the translucent part of the keycap 1, so that the keycap as a whole presents a predetermined light sensation, that is, the setting of the edges can improve the light sensation of refraction.

[0016] More specifically, the refractive texture is a diamond texture or a concave-convex wavy texture, which makes the internal structure softer through a softer curvature, and the corresponding light is also refracted more softly, wherein the multiple cut edges of a diamond can be used as reference to achieve the refraction of light.

[0017] In the embodiment of the utility model, the refractive structure 11 and the key cap are integrally injection molded, thereby reducing production costs. Of course, the refractive effect of the key cap can also be improved by spraying refractive particles to form a protruding refractive structure 11.

[0018] Furthermore, the bottom wall of the key cap is provided with a positioning column 2 extending downward, and the positioning column 2 is in a cross shape. The positioning column 2 is used to be installed on the key shaft.

[0019] In the embodiment of the utility model, the outer wall of the positioning column 2 is coated with a reflective layer, so that the light is refracted toward the inner wall of the keycap, thereby improving the brightness of the inner wall of the keycap.

[0020] Specifically, the positioning column 2 is a translucent structure, so that part of the light refracted by the inner wall will be absorbed, thereby making the light softer.

[0021] In the embodiment of the utility model, the outer peripheral wall of the key cap is an inclined surface.

[0022] In an embodiment of the utility model, the light source is an RGB lamp.

[0023] In an embodiment of the utility model, the top wall of the key cap is provided with predetermined characters, and the characters are concavely engraved or coated with light-shielding paint, so that the characters are clearer.

[0024] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
