Keyboard device

Abstract

The invention provides a keyboard device, comprising a shell, at least one key cap group and a pushing mechanism, wherein the shell is provided with a plurality of key openings; each key cap group comprises at least one key cap, and the at least one key caps are aligned with each other and arranged in the same linear direction side by side; each key cap comprises a front part and a back part; thefront parts are contained in the key openings, and each back part is provided with at least one convex lug in a protruding way respectively at the two sides of the arrangement direction of the key caps of the corresponding key cap group; the key caps are pushed to go up or down relative to the shell by controlling the position change of the convex lugs. Therefore, when the key caps are contractedin the key openings of the shell, the keyboard device is maintained to be in an ultra-thin state and presents a thinner appearance; furthermore, when the key caps are contracted in the key openings ofthe shell, a press input operation is not available to a user; when the key caps are lifted out of the upper surface of the shell, the press input operation is available to the user, and the undesired input caused by accidentally touching keys is effectively prevented.

Description

technical field [0001] The invention relates to the field of keyboards, in particular to a keyboard device with liftable keys. Background technique [0002] With the demand for lightweight and thinner electronic equipment such as notebook computers and desktop computers, keyboards, as commonly used input devices, are also developing towards lightweight and ultra-thin directions. How to design thinner keyboards is a design in this field. topic. In the design of some electronic devices, the keyboard surface including the keys needs to be turned into a support surface in one state to be supported on a plane such as a desktop or held by the user. At this time, the keyboard needs to be protected against operation. In addition, in order to temporarily shelve the electronic device during use to deal with other affairs, it is necessary to prevent operation of the keyboard, so as to prevent others from touching the keyboard and affecting the operation of the electronic device, or le...
