Description

An intelligent mechanical keyboard without positioning board

technical field

The utility model relates to the technical field of mechanical keyboards, in particular to an intelligent metal-free positioning board or a PC positioning board mechanical keyboard.

Background technique

A keyboard is an instruction and data input device used to operate equipment, and also refers to a group of function keys arranged to operate a machine or equipment through the system. The keyboard is the most commonly used and most important input device.

A mechanical keyboard is a type of keyboard. From a structural point of view, each key of the mechanical keyboard has a separate switch to control the closure. This switch is also called a "shaft". According to the classification of micro switches, mechanical keyboards It can be divided into traditional tea shaft, green shaft, white shaft, black shaft, red shaft, Romer-G and optical shaft. It is precisely because each button is composed of an independent micro-movement, so the buttons have a strong sense of paragraph, resulting in a special feel.

According to the working principle of the keyboard and the way of pressing the keys, it can be divided into four types: mechanical keyboard, plastic film keyboard, conductive rubber keyboard and non-contact electrostatic capacitive keyboard. Among them, the mechanical keyboard is referred to as a mechanical keyboard, and each key has a separate Switch (that is, a switch) to control the closure. Mechanical keyboards have been developed as a representative of high-end products until today. The current situation is that more and more computer users and game players have put forward higher requirements for the comfort, feel and quality of using computers. As one of the peripherals There have also been some changes in the keyboard, and mechanical keyboards have begun to be recognized by more and more friends who pursue quality and feel. While pursuing comfort, feel, and quality, they are also constantly enhancing their functional requirements for keyboard performance and aesthetics, such as the dustproof and noise reduction performance of mechanical keyboards.

The existing Chinese patent whose notification number can be referred to is CN204117919U discloses a mechanical keyboard with a completely waterproof and noise-reducing structure, including an upper cover, a waterproof sheet, an iron plate, a lower cover, buttons and a PCB board. There are double-layer waterproof ribs around the button area of the cover, and the waterproof sheet is provided with a through hole corresponding to the position of each button. The button includes a keycap and a mechanical switch, the keycap is installed on the mechanical switch, and the waterproof The outer circumference of the sheet is provided with a U-shaped sealing ring, the upper end of the through-hole periphery of the waterproof sheet is provided with a forming boss, and the periphery of the waterproof sheet is provided with a U-shaped sealing ring.
