Description

Technical Field

[0001] This utility model relates to the field of keyboards, and in particular to an X-shaped magnetic induction scissor-switch key and a mechanical keyboard. Background Technology

[0002] Existing magnetic axis keyboards use conventional rail-type key presses, which take up a lot of space, have a short lifespan due to the short pressing distance, uneven pressure on the keycaps, poor balance, and poor feel.

[0003] 1. The ultra-thin magnetic shaft button uses a conventional rail-type pressing mechanism, which takes up a lot of space and is inconvenient to install.

[0004] 2. The ultra-thin magnetic axis buttons use conventional rail-type pressing, resulting in poor button balance and short button life.

[0005] 3. The ultra-thin magnetic axis buttons use a conventional rail-type pressing method, resulting in poor button balance and a poor tactile feel.

[0006] The technical solution with authorization announcement number CN219512994U and utility model patent name "A Thin Magnetic Induction Key Structure" includes a keycap, a telescopic spring, a scissor-switch bracket, a base, and a circuit board arranged from top to bottom. The scissor-switch bracket includes an inner bracket and an outer bracket that are hinged together. The telescopic spring is disposed on the base and abuts against the keycap. Magnets and a fixed shaft are disposed at both ends of the inner bracket. A Hall effect IC that cooperates with the magnet is disposed on the circuit board. A torsion spring is sleeved on the fixed shaft. The short torsion arm of the torsion spring is in contact with the side wall of the inner bracket. The long torsion arm of the torsion spring cooperates with a spring clip disposed on the inner bracket. A boss that cooperates with the long torsion arm is disposed at the lower end of the keycap.

[0007] In the above technical solution, the magnet faces the sensing surface of the Hall chip and always faces the sensing surface of the Hall chip when the magnet moves. Its working principle is: using the linear Hall to set the reference voltage value as the voltage threshold to set the opening and closing of the switch. It is greatly affected by external interference, the distance between the Hall and the magnet, the consistency of the conduction point is not good, the user experience is poor, and the cost of using AD is also high.

[0008] Another type of mechanical keyboard uses a magnetic axis. Its magnet is directly facing the Hall effect chip, and then halfway through the movement, the polarity of the small magnet is reversed by a mechanical device to obtain a switch signal. This technology is too complex and expensive, and the key lifespan is short, making it unsuitable for keyboards that are used more than ten million times. Utility Model Content
