Technical Field
[0001] This utility model relates to the field of keyboard knobs, specifically to a keyboard knob with a magnetically detachable structure. Background Technology
[0002] As an innovative input device, the keyboard knob has been widely used in consumer electronics products, especially high-end keyboards, in recent years. It not only enhances the functionality of the keyboard but also provides users with a more intuitive and convenient operating experience. Keyboard knobs are mainly used in scenarios requiring frequent settings adjustments or specific shortcut operations, such as multimedia control, quick switching in office software, and parameter adjustments in graphic design software. With its unique design, the keyboard knob greatly improves user efficiency and satisfaction.
[0003] Existing keyboard knobs are typically integrated into specific locations on the keyboard, allowing users to execute different commands through rotation, pressing, or pressing and rotating. Technically, a keyboard knob mainly consists of a rotating spindle, an outer ring structure (usually composed of multiple copper plates), and a circuitry connecting to the keyboard's mainboard. When the rotating spindle contacts the copper plates in the ring structure, it changes the electrical level in the circuit, triggering the corresponding operation command.
[0004] However, despite the achievements of existing keyboard knobs in terms of functionality and user experience, there are still some significant drawbacks. Most existing keyboard knobs are fixed in place, meaning that once installed on the keyboard, they cannot be easily removed or replaced, which limits the user's flexibility. Users cannot adjust the position or type of the knob according to their actual needs. At the same time, the installation and positioning effect of existing keyboard knobs is poor, which is not conducive to convenient installation and removal, and affects the installation and use of keyboard knobs.

[0014] Furthermore, as described above, the bottom of the connecting sleeve has a connecting groove for mating and installing the magnetic ring, and the base has a through hole that communicates with the positioning hole.
[0015] The insertion groove and the mating protrusion on the base fit together precisely, simplifying the installation steps of the knob, providing clear positioning guidance, avoiding installation misalignment, and improving assembly efficiency.
[0016] Meanwhile, the magnetic attraction between the upper and lower magnetic rings further improves the convenience and reliability of docking and installation.
[0017] Furthermore, as described above, the button cap is attached to a detachable decorative cover.
[0018] The removable decorative cover allows users to freely change the appearance style to meet their individual needs without replacing the entire knob, reducing costs and improving the user experience.
[0019] The beneficial effects of this utility model are as follows: The button cap is tightly connected to the connecting shaft and the connecting sleeve. The insertion groove at the bottom of the connecting sleeve and the mating protrusion on the base are used for insertion and assembly, which further enhances the connection stability between the knob and the base and reduces the possibility of the knob shaking or shifting during use. At the same time, this insertion method also makes the installation process more convenient and faster. In addition, the magnetic pairing of the upper and lower magnetic rings enables convenient installation and removal of the keyboard knob. The magnetic attraction enhances the connection strength between the knob and the base, making the knob more stable and reliable during use. The presence of magnetic attraction also makes the disassembly process easier and less strenuous. Users can easily adjust the position of the knob or replace it with different types of knobs according to their actual needs, which greatly improves the user's flexibility and user experience.
