Description

Technical Field

[0001] This utility model relates to the field of key switch technology, and in particular to a ring-shaped light guide magnetic shaft used in keyboard switches. Background Technology

[0002] In the mechanical keyboard industry, backlighting has become a crucial feature for enhancing user experience. One of the key components for achieving backlighting is the light guide pillar housed within the switch body. Currently, most common switch light guide pillars on the market are sheet-like or single-sided pillar structures with a simple light path design, typically guiding light only from one side of the switch. This unidirectional light guide structure results in uneven light distribution under the keycaps, with the side closer to the LEDs being brighter and the side further away noticeably darker, creating a pronounced "yin-yang" lighting effect that affects the overall aesthetics of the keyboard and the comfort of character recognition. Furthermore, this structure has stringent requirements for the installation position of the LEDs, offering low tolerance for errors. Therefore, there is an urgent need for a light guide pillar structure that can achieve uniform, omnidirectional illumination to improve the keyboard's visual appeal and product competitiveness. Utility Model Content

[0003] The purpose of this invention is to provide a ring-shaped light guide column magnetic shaft that can achieve omnidirectional light guiding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A ring-shaped light guide magnetic shaft includes a rubber cap and a base, the rubber cap and the base being fastened together to form a shaft housing, and further includes: The button is located inside the rubber cover; A connecting block is disposed inside the push button and is installed together with the push button inside the rubber cover; A magnet is disposed within the connecting block; A ring-shaped light guide column is set on the upper surface of the base to achieve omnidirectional light guiding; An elastic element, located within the base, provides the reset force for the button.

[0005] Furthermore, a positioning block is provided on the annular light guide post, and a corresponding positioning notch is provided on the base.

[0006] Furthermore, the base extends outward to form several protrusions for placing the annular light guide column.

[0007] Furthermore, the upper surface of the base is provided with a first buckle for fixing the annular light guide column, and the adhesive cover is provided with a corresponding first slot for accommodating the first buckle.

[0008] Furthermore, the lower surface of the rubber cap is provided with a number of second buckles, and the base is provided with a number of matching second slots.

[0009] Furthermore, the cap has two symmetrical guide grooves, and the pressing surface is provided with guide strips accordingly.

[0010] Furthermore, the base is provided with a cylindrical groove for mounting the elastic element.

[0011] Furthermore, both the cap and the base are semi-circular structures.

[0012] Furthermore, four second buckles are evenly distributed on the lower surface of the rubber cap, and four second slots are correspondingly provided on the base.

[0013] Furthermore, the elastic element is a spring.

[0014] The beneficial effects of this utility model are that, compared with the prior art, the annular light guide magnetic shaft provided by this utility model has the following significant advantages: Superior optical performance: Through the innovative ring light guide column structure, 360° omnidirectional light collection and mixing of LED light source is achieved. The light can be emitted evenly and fully from the upper surface of the ring, completely eliminating the "yin-yang surface" or uneven brightness phenomenon under the keycap caused by the traditional one-way light guide structure. This makes the keycap characters illuminated evenly and fully, greatly improving the visual effect and user experience. High structural stability and precise positioning: The positioning block on the ring light guide column and the positioning notch on the base cooperate with each other, as well as the support of the base boss, to ensure that the light guide column does not shake or deviate after assembly, thereby ensuring the consistency and stability of the optical path, and avoiding abnormal noise or changes in feel caused by component displacement. Easy and efficient assembly: The rubber cap and base are quickly fastened together through the cooperation of multiple sets of second buckles and second slots. At the same time, the first buckle on the base and the first slot on the rubber cap are used to jointly fix the annular light guide column. This modular buckle connection design simplifies the assembly process, reduces assembly difficulty, and helps to improve production efficiency and reduce production costs. Precise motion guidance and consistent feel: The symmetrical guide grooves inside the rubber cover work together with the guide strips on the buttons to provide precise vertical guidance for the pressing and rebounding of the buttons, effectively preventing the buttons from getting stuck, shaking or tilting during movement, and ensuring the consistency and smoothness of the triggering feel of all switches. Compact structure and high reliability: The overall structure is reasonably laid out, with the magnet built into the sub-connector block and the button, and the elastic element confined in the cylindrical groove of the base. This makes the internal structure of the shaft compact, and the various components work together stably and reliably, thus extending the service life of the product. Attached Figure Description
