Description

Technical Field

[0001] The present invention relates to the technical field of mechanical keyboard design and manufacturing, and particularly relates to an electrically adjustable key switch. Background Art

[0002] A keyboard is a device for inputting instructions and data to operate a device, and also refers to a set of function keys (such as a typewriter keyboard or a computer keyboard) arranged to operate a machine or device. The trigger shaft body involved in this application can be, in addition to the input shaft body of a keyboard, a micro switch or a button of a game controller, etc. In recent years, as people's living standards have gradually improved, people's requirements for keyboards have also been gradually increasing. From the current keyboard market, keyboards are classified into membrane keyboards and mechanical keyboards according to their architectures. Among them, mechanical keyboards are favored by game players and IT practitioners because they can produce a special feel suitable for game entertainment or text input. The advantages of mechanical keyboards are excellent feel and clear classification, which can meet the needs of different customer groups. Moreover, the service life of mechanical keyboards is extremely long, many times that of membrane keyboards, and the feel of mechanical keyboards remains unchanged even after being used for a long time. This is an important reason why many users choose mechanical keyboards.

[0003] Structurally, each key of a mechanical keyboard has a separate switch to control closing, and this switch is also called an "axis" or "shaft body". Currently, Cherry MX axes can be roughly divided into audible tactile axes, silent tactile axes, and linear axes. For example, the audible tactile axis in the US Patent (US4467160) is the blue switch, and the green switch, deep blue switch, brown switch, cream switch, etc. are all based on the audible tactile axis body and have replaced springs with different pressure grams. The silent tactile axis is the brown switch, and the caramel switch, gray switch, white switch, etc. are all based on the silent tactile axis body and have replaced springs with different pressure grams. The linear axis is the black switch, and the red switch, silver switch, white switch, gray switch, etc. are all based on the linear axis body and have replaced springs with different pressure grams. Among them, the silver switch has a shorter key travel for shaft body triggering compared to other shaft bodies. The more popular combination axis on the market is the Holy Panda switch, which is a combination axis based on the silent tactile axis and advances the key press paragraph travel. The paragraph feel, key travel for triggering, and pressure grams of each axis are different, and the feel varies greatly; among them, the black switch is suitable for game entertainment, and the blue switch is suitable for text input. According to different personal habits and uses of consumers, there will be different requirements for the feel of the keyboard. However, the variety of shaft structures also brings certain troubles to the purchase and use of consumers to a certain extent. For example, some users need to perform a large amount of text input during working hours and spend more time on game entertainment during their spare time. The required key feel has a large span and is two completely opposite extremes.

[0004] Therefore, how to enable a single axis body to have multiple pressing sensations and multiple trigger key travel distances is a technical problem that urgently needs to be solved at present. Although the technical solution of the invention patent application with the application number 2021111055347 previously submitted by the applicant has solved the above problems, there is still the problem of inconvenient adjustment. It requires a mechanical keyboard repairer with a relatively high level of professionalism or rich experience or a user with strong hands-on ability to adjust it well, and there is no specific quantitative standard for the adjustment parameters. This application can well solve this problem. Summary of the Invention
