Description

Technical Field

[0001] This utility model belongs to the field of keycap technology, specifically relating to a filler-type keycap. Background Technology

[0002] In the keyboard keycap manufacturing industry, laser engraving is the mainstream technology for generating characters. This process creates indentations on the keycap surface using laser etching or by directly burning color to reveal the characters. Traditional laser engraving can only produce monochrome characters (usually white or black), limiting the ability to create multi-color characters and severely restricting the visual appeal and personalization needs of products.

[0005] The top surface of the base is provided with a filling groove, the filling groove is shaped like a character graphic, and the filling groove is filled with a coating layer;

[0006] The transparent cap is fixedly connected to the top surface of the base, and the transparent cap completely covers the top surface of the base.

[0007] Preferably, the filling groove is located on the rear side of the middle position on the top surface of the base.

[0008] Preferably, the transparent cap is detachably attached to the top surface of the base.

[0009] Preferably, the top corner of the base is recessed to form a groove, and the transparent cap is provided with a limiting part. The limiting part is continuously provided along the edge of the transparent cap and is engaged in the groove and limited by the inner sidewall of the groove.

[0010] Preferably, the inner wall of the groove is provided with a slot, and the inner wall of the limiting part is provided with a protrusion, which is engaged in the slot.

[0011] Preferably, the bump is spherical.

[0012] Preferably, the bayonet extends into the inner cavity of the base.

[0013] Preferably, the groove is provided on both sides opposite to each other, and the limiting part is provided on both inner sidewalls opposite to each other.

[0014] Preferably, the outer wall of the base is flush with the outer wall of the limiting part.

[0015] Preferably, the top surface of the base and the bottom surface of the transparent cap are fitted with a clearance.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The coating layer filling the filler groove supports the selection of any color as needed, which enhances visual appeal and user personalization freedom, breaking through the color limitations of traditional monochrome characters.

[0018] The coating layer is located inside the filler tank and is covered by a transparent cap. Users' fingers only touch the surface of the cap, which can prevent the coating layer from being worn, peeling off, or oxidizing and discoloring, thus improving the service life of the coating layer.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] A type of filler keycap, see Figures 1-4 It includes a light-shielding base 100 and a transparent cap 200 on the base 100. The base 100 is provided with reinforcing ribs 110 and cross-shaped connecting posts 120, similar to those of a traditional keycap.

[0027] A filling groove 130 is provided on the rear side of the center of the top surface of the base 100. The depth of the filling groove 130 can be set as needed. The filling groove 130 is shaped like a character graphic, such as "ESC" in this embodiment. The filling groove 130 is filled with ink, which forms a coating layer 140 after curing. The coating layer 140 filled in the filling groove 130 supports the selection of any color as needed, which can enhance visual expression and user personalization freedom, breaking through the color limitations of traditional monochrome characters.

[0028] The transparent cap 200 is fixedly connected to the top surface of the base 100. The transparent cap 200 completely covers the top surface of the base 100. When using the product, the user's fingers only touch the surface of the cap. This can prevent the coating layer 140 from being worn, peeling off, or oxidizing and discoloring, and improve the service life of the coating layer 140.

[0029] In this embodiment, the transparent cap 200 is detachably connected to the top surface of the base 100. In this way, the consumer can remove the transparent cap 200 to refill the filling groove 130 with ink to keep the characters clear, and the consumer can change the color according to their own preferences.

[0030] The base 100 has a recessed groove 150 at its top corner, and the transparent cap 200 has a limiting part 210. The limiting part 210 is continuously provided along the edge of the transparent cap 200. After the transparent cap 200 is placed on the base 100, the limiting part 210 is engaged with the inner wall of the groove 150. The continuous limiting structure between the groove 150 and the limiting part 210 improves the dustproof effect between the base 100 and the transparent cap 200.

[0031] The inner wall of the groove 150 is provided with a snap-fit ​​151, and the inner wall of the limiting part 210 is provided with a protrusion 211. In this embodiment, only two snap-fits 151 are provided on each of the opposite sides of the groove 150, and two protrusions 211 are provided on each of the two opposite inner walls of the limiting part 210. After the transparent cap 200 is placed on the base 100, the protrusions 211 engage with the snap-fits 151, thereby fixing the transparent cap 200 to the base 100. The transparent cap 200 is fixed by the cooperation of the snap-fits 151 and the protrusions 211, which has a simple structure and is also convenient for disassembling the transparent cap 200.

[0032] In order to facilitate the disassembly and assembly of the transparent cap 200, the protrusion 211 is spherical, which reduces the resistance and operational difficulty during the disassembly and assembly of the transparent cap 200.

[0033] To ensure the reliable connection between the transparent cap 200 and the base 100, the latch 151 extends into the inner cavity of the base 100, allowing the protrusion 211 to be set larger so that it can be snapped into the inner cavity of the base 100, thus improving the fixing effect.

[0034] In this embodiment, the outer wall of the base 100 is flush with the outer wall of the limiting part 210, which improves the appearance of the keycap.

[0035] In this embodiment, there is a gap fit between the top surface of the base 100 and the bottom surface of the transparent cap 200. This gap enables the assembly of the base 100 and the transparent cap 200, preventing them from being unable to be assembled due to the production of tribute tea. On the other hand, the gap between the two forms a heat insulation layer, which reduces the heat conduction to the coating layer 140 when a hot object is placed on the keycap, preventing problems such as ink yellowing.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
