Liftable and foldable key and lifting key assembly with same

Abstract

The invention relates to the technical field of keys, and particularly relates to a liftable and foldable key and a lifting key assembly with the same. The key comprises a base, a movable support anda key cap, wherein the base comprises a key starting plate, a fixed plate and a movable plate which are sequentially arranged from top to bottom, the key starting plate is arranged above the fixed plate in a sliding mode, and the movable plate is arranged below the fixed plate in a sliding mode; the movable support comprises a first support and a second support, one end of the first support is hinged to the fixed plate, and the other end of the first support is hinged to the key cap; one end of the second support is hinged to the movable plate, and the other end of the second support is hingedto the key cap; and a jacking block is convexly arranged on the side, which is close to the key cap, of the key starting plate. According to the invention, a keyboard is thinned by means of lifting the key cap, so that the stroke of the key does not need to be shortened when the key is used, the keyboard can be thinned while the original comfort and feedback feeling of the key are maintained, andthe failure rate of the key is reduced.

Description

technical field [0001] The invention relates to the technical field of keys, in particular to a liftable and retractable key and a lift key assembly having the key. Background technique [0002] At present, ultra-light and ultra-thin has become the main development direction of notebook computers. The main performance is that notebook computers are getting thinner and thinner. In order to reduce the height of the keyboard, many manufacturers use keyboards with shorter keystrokes to replace keyboards with longer strokes. . However, with the shortened key travel, the keys are uncomfortable to press, with a poor tactile feel and lack of feedback. For example: Apple's MacBook Pro adopts a keyboard with butterfly feet. Although the stroke of the keys is shortened and the height of the keyboard is reduced, consumers generally report that the keys feel bad. Moreover, because the design of the butterfly feet is too precise, as long as a little dust or hair falls into the keyboard,...

However, with the shortened key travel, the keys are uncomfortable to press, with a poor tactile feel and insufficient feedback

For example: Apple's MacBook Pro adopts a keyboard with butterfly feet. Although the travel of the keys is shortened and the height of the keyboard is reduced, consumers generally report that the keys feel bad.

Moreover, because the design of the butterfly feet is too precise, as long as a little dust or hair falls into the keyboard, it will cause serious failures and affect the normal use of the computer.

Therefore, the defect of the technical scheme of reducing the thickness of the keyboard by reducing the stroke of the key is very obvious, and an effective solution is urgently needed
