Scissor keyboard key structure

Abstract

The invention provides a scissor keyboard key structure, which comprises a base, a thin film circuit board arranged on the base, an elastic piece arranged on the thin film circuit board, a scissor support arranged above the elastic piece and arranged on the base, and a key cap arranged on the scissor support, wherein the scissor support comprises an inner support and an outer support in rotary connection onto the outer side of the inner support; the inner support and the outer support form a dual-lever structure; one side, facing the elastic piece, of the inner support is provided with a convex part; the thin film circuit board is provided with a circuit contact; and the elastic piece is arranged on the circuit contact in a corresponding covering mode. When the key cap is pressed, the convex part of the scissor support presses the elastic piece, and the elastic piece presses the thin film circuit board to enable the circuit contact of the thin film circuit board to be contacted and conducted. According to the scissor keyboard key structure provided by the invention, the overall key is thinner, the stroke is larger, the hand feeling is better, the striking force at each position of the key cap is small and balanced in the case of use, the use is comfortable, the sound is small, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a key structure of a scissors keyboard. Background technique [0002] With the development of information technology and people's continuous pursuit of portable electronic products, keyboards are also widely used as a typical input device for electronic products such as notebook computers and tablet computers. [0003] With the continuous innovation of technology and the continuous pursuit of the technological sense of electronic products by users, the keyboard structure is also developing towards miniaturization and thinning. Many existing key structures can no longer meet the needs of ultra-thin electronic products. In addition, during the use of many keyboards with existing structures, when the keycap is pressed, the percussion force at the upper left corner, the upper right corner, the lower left corner, the lower right corner, and the center of the key is relatively large ...

Problems solved by technology

[0003] With the continuous innovation of technology and the continuous pursuit of the technological sense of electronic products by users, the keyboard structure is also developing towards miniaturization and thinning. Many existing key structures can no longer meet the needs of ultra-thin electronic products.

In addition, during the use of many keyboards with existing structures, when the keycap is pressed, the percussion force at the upper left corner, the upper right corner, the lower left corner, the lower right corner, and the center of the key is relatively strong and unbalanced, and it is easy to use for a long time. Fatigue, relatively uncomfortable hand feeling, and loud knocking sound
