Description
Technical field
The present invention relates to input unit, particularly a kind of keyboard.
Background technology
One of important need of portable equipment is the demand to the thinness of keyboard, and convenient simultaneously frivolous keyboard also has a wide range of applications in multiple field.
In the prior art, for reducing the thickness of keyboard, a kind of method is to use the mode of electromagnet, for example, the button of keyboard is made up of the support open tubular column under keycap and the keycap, is provided with electromagnet in the support column, a cylinder at its center can be risen after the energising, and keycap is risen.The weak point of this method is: owing to the use electromagnet has increased power consumption, and because the magnetic core of electromagnet can not be too thin, thereby make the keyboard of being produced can not reach desirable thinness.
In addition, in the prior art, have the button sense in use, also can adopt touch sensible or make the mode of circuit connection reduce the thickness of keyboard by pushing of slight distance for making keyboard.But the weak point of said method is the sensation that does not have button when using keyboard, has influenced convenience and usability.
Summary of the invention
The objective of the invention is problem at above-mentioned prior art existence, a kind of keyboard is provided, can reduce power consumption, reach ultra-thin light and handy practical effect, can strengthen button sense and convenience when using, and can make part key projection, thereby can strengthen flexibility and extensive use according to user's demand.
According to an aspect of the present invention, provide a kind of keyboard, having comprised: the keyboard end face, be embedded with several first key buttons, each first key button includes first magnet; Keyboard base, be stacked and placed on keyboard end face below, its surface towards the keyboard end face is provided with at least one second magnet, and wherein second magnet is relative one by one with described first key button to small part, and be set to the first relative key button in the state inhaled mutually of the first magnet magnetic; The switching circuit layer is located between keyboard end face and the keyboard base, is used for exporting when pressing first key button corresponding push button signalling.
Technique scheme is inhaled the thinness that keeps keyboard mutually by the magnetic between second magnet in first magnet in first key button and the keyboard base, do not need simultaneously power consumption again, and can be according to user's demand, the quantity and the position of second magnet relative with first magnet in first key button are set, thereby can make part key projection, satisfying the needs of user individual, thereby flexibility and extensive use have been strengthened.
Preferably, described first magnet and second magnet can be sheet, and can according in the practical application to the requirement of thinness and its thinness is set flexibly.
Preferably, in the technique scheme, described keyboard also can comprise: mobile device, be used for when key journey state is arranged, making between described keyboard base and the described keyboard end face relative translation takes place, so that at least one second magnet is relative one by one with described first key button after the relative translation, and for relative first key button in the state that repels each other of the first magnet magnetic.
Among the application, described have key journey state to be meant demand according to the user, and the key button to small part of keyboard is projected upwards because of the magnetic effect of repelling each other, so that strengthen the button sense when using; Described slim state is meant the demand according to the user, the key button to small part of keyboard is adsorbed, so that reduce the thickness of keyboard downwards because of the magnetic interattraction.
By described mobile device, can be when needing key journey state, make between described keyboard base and the described keyboard end face relative translation takes place, so that the state that repels each other for magnetic between first magnet in several first key buttons and relative second magnet after moving, thereby make these key buttons to upper process, therefore can strengthen the button sense when using.And by this mobile device described first key button is become to upper process by downward absorption, convenient and swift, can change state as required at any time, strengthened the convenience and the flexibility of operation, also need not power consumption simultaneously.
