Energising produce magnetic field, with band magnetic keycap mutually exclusive jack-up keycap, support fix, all keycaps float to and tradition
The height that keyboard is the same, for user, to the experience that user is pretty good.
Accompanying drawing explanation
Accompanying drawing 1 and accompanying drawing 2 describe press-key structure of the prior art；
Accompanying drawing 3 and accompanying drawing 4 describe according to press-key structure of the present utility model；
Accompanying drawing 5 to 7 describes the embodiment one according to notebook computer of the present utility model；
Accompanying drawing 8 describes the embodiment two according to notebook computer of the present utility model.
Detailed description of the invention
Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energy
It is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
In the preferred embodiment of the application, the preferably selection X-shaped support of this utility model medium-height trestle.
Accompanying drawing 3 and accompanying drawing 4 describe according to press-key structure of the present utility model, including X-shaped support 1, are arranged on X-shaped support
Thin film switch 2 below 1, be arranged on the keycap 3 above X-shaped support 1, at thin film switch 2, be provided with solenoid 6, keycap 3 to
Small part is made up of magnetic material 7, and solenoid 6 is energized and produces the magnetic field acting on magnetic material 7, and keycap 3 is scolded in magnetic field
By jack-up under power effect, contact when keycap 3 overcomes magnetic field repulsive force to make to be positioned at the trigger point 5 bottom keycap 3 under external force
During thin film switch 2, button is connected and sends instruction, and after having triggered, keyboard restores to the original state under the effect of magnetic force.
It is pointed out that and the thinnest flat thin magnet can be set in the lower section of keycap 3, it is also possible to be the trigger point 5 of keycap 3
It is made up of flat thin magnet, it is also possible to be that keycap 3 entirety is made up of flat thin magnet.
When this structure is applied to notebook computer, when start enters duty (S0), all coils energising produces
Magnetic field, magnetic keycap is mutually exclusive with carrying, and jack-up keycap is fixed by X-shaped support, and the most all keycaps all float for user
Use；When notebook computer carries out lid operation, enters sleep, dormancy, off-mode, coil no longer has electric current, and magnetic disappears
Losing, keycap sinks under gravity, reduces keyboard height, thus decreases the integral thickness of notebook computer.Can see
Going out, have employed the keyboard of this structure, notebook computer is without arranging rubber cushion isolation screen, and keyboard sets without carrying out sinking again
Meter.
Owing to have employed the button of this structure, it is also possible to increase dynamics regulation unit, arranged suitably by X-shaped support
Key journey, such as key journey can also be adjustable, and cooperation dynamics regulation unit is adjusted by the size of current of regulation solenoid 6
The dynamics size of the button of whole keycap 3, such that it is able to improve the feel of existing membrane keyboard.
Accompanying drawing 5 to 7 describes the embodiment one according to notebook computer of the present utility model, and this notebook computer includes this
Body, be arranged at the keyboard of body, rotate and be installed on the screen of body, body is provided with can the switch 8 of elastic telescopic, work as screen
When rotating opening is to certain angle, this switch 8 is in the state of upspringing, and is used for controlling solenoid 6 and is energized so that every in keyboard
Individual button is in the state of upspringing；When screen rotates and closes to certain angle, this switch 8 is in retracted mode, is used for controlling
Solenoid 6 processed power-off so that in keyboard each button be in sinking state.Above-mentioned predetermined angular can be by switch
Bounce amount determines.
Accompanying drawing 8 describes the embodiment two according to notebook computer of the present utility model, in this embodiment, turning of screen
Being provided with rotating switch 9 at axle, when screen rotating opening, this rotating switch 9 controls solenoid 6 and is energized so that every in keyboard
Individual button is in the state of upspringing；When screen rotates and closes, this rotating switch 9 controls solenoid 6 power-off so that in keyboard
Each button is in sinking state.Above-mentioned predetermined angular can be determined by the trigger angle of rotating switch.
In another embodiment, the energising of solenoid 6 or off-position are by the LID_SWITCH of notebook computer
Signal controls.Make the energising of solenoid or the signal of power-off Tong Bu with the LID_SWITCH signal of computer, LID_SWITCH
Signal sends the signal making keyboard lower coil power-off while sending, or directly shares LID_SWITCH signal to making under keyboard
The signal of coil blackout.LID_SWITCH signal is that active computer passes through to weld an induced flux change on mainboard
IC, coordinates the small magnet generation action installed below display, and when magnetic flux change to a certain value, IC sends LID_SWITCH
Signal, notifies computer, and user the most carries out uncapping or closing lid action.
According to notebook computer of the present utility model when sleep, dormancy, shutdown, solenoid no longer has electric current, magnetic
Disappearing, keycap sinks, keyboard height reduction, thus decreases notebook integral thickness；In normal operation, all coils
Energising produce magnetic field, with band magnetic keycap mutually exclusive jack-up keycap, X-shaped support fix, all keycaps float to
The height that conventional keyboard is the same, for user, to the experience that user is pretty good.
Embodiment of above only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this skill
The people of art understands content of the present utility model and is carried out, and can not limit protection domain of the present utility model with this, all
