Abstract

The present disclosure discloses a keyboard including a base plate, membrane circuit board, a plurality of keys and a frame. The base plate includes a plurality of assembly areas and a first opening. The first opening is disposed between some said assembly areas. The membrane circuit board is disposed above the base plate. The membrane circuit board includes a second opening corresponding in position to the first opening, respectively. The frame is disposed above the base plate, and the membrane circuit board is disposed between the base plate and the frame. The frame blocks the first and second openings. The frame includes receiving portions corresponding in position to the assembly areas. The keys pass through the receiving portions and are fixed to the assembly areas of the base plate, respectively. Gaps between the frame and keys, the first and second openings jointly form an air current channel.

Description

technical field [0001] The present invention relates to a keyboard. Background technique [0002] As far as current computer usage habits are concerned, the keyboard is one of the indispensable input devices. Whether it is the computer itself or its peripheral products, they are all developing towards the design concept of light, thin, short and small. The keyboard has also changed from the early large structure to a thin keyboard. The main structure of the thin keyboard includes a bottom plate, a thin film circuit board and a plurality of keys. In addition, the thin keyboard is often equipped with a backlight module to form a luminous keyboard. [0003] Generally speaking, there will be gaps between the keys. In order to achieve effects such as dustproofing or avoiding light leakage, the upper layer of the keyboard will increase the setting frame. The frame has a plurality of openings for accommodating the keys, so that the gaps between the keys can be covered by the f...
