Abstract
The utility model discloses a magnetic suspension keyboard, which includes: a bottom panel, keys, and electromagnets connected with the bottom panel and corresponding to the keys. The bottom panel is connected with a cover, and the cover is provided with key chambers capable of accommodating the electromagnets. Each of the key chambers is provided with a key hole at the top part. The keys are in a hat shape, with the lower ends slidablly connected with the inner walls of the key chambers and the upper ends exit the key holes. The keys are capable of moving along the key chambers upwardly and downwardly, and the lower ends of the keys are under constrictions of the key hole walls, which can prevent the keys from dropping out of the key holes. The keys are provided with permanent magnets at the top parts. When the electromagnets are powered on, the permanent magnets can suspend above the electromagnets under the action of magnetic force of the electromagnets. Key sensing coils are disposed outside the electromagnets. The magnetic suspension keyboard has keys that move smoothly up and down with small noise, and the keys are closely combined to the cover thereby preventing particles from dropping in the keyboard and enabling convenient cleaning. The suspension degrees of the keys are adjustable by changing the currents in the coils, so that the keyboard is convenient to use and customized setting of the keyboard can be realized.
Description
Technical field
The utility model belongs to the computer keyboard technique field, especially relates to a kind of button by the keyboard of magnetic levitation.
Background technology
The existing computer keyboard great majority that use are contact, condenser type and induction type.During the operation of tradition tactile keyboard, feel more stiff not soft, it is bigger to produce noise when knocking.Food slag or foreign matter etc. enter in the slit of keyboard easily, and are difficult to cleaning, and the performance of keyboard can descend in the course of time, and the life-span also shortens.Tactile keyboard is influenced by button easily, misoperation occurs.Simultaneously, the button counter-force of existing keyboard is fixed, and is difficult to satisfy the individual demand of different people.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of use noise little, be convenient to clean and by the adjustable keyboard of bonding force.
For solving the problems of the technologies described above.The utility model comprises chassis and button, and its design feature is also to comprise with the chassis connecting and the electromagnet corresponding with button, and be connected to cover cap on the described chassis, cover cap is provided with the key chamber that can hold electromagnet, and this key top of chamber is provided with keyhole; Described button is the cap shape, and its lower end and key cavity wall slide and join, and the upper end passes keyhole, and button can move up and down along the key chamber, and the button lower end is limited by the keyhole wall, and it can not deviate from from keyhole; Key-top is provided with permanent magnet, and after the electromagnet energising, permanent magnet is subjected to magneticaction to drive button and is suspended in electromagnet top, and electromagnet is provided with key induced coil outward.
Preferably the magnetic coil of described key induced coil and electromagnet is same coil, and the push button signalling loop is connected with the magnetic coil of electromagnet.
The beneficial effects of the utility model are: each function key is made up of electromagnet and button, and button is provided with permanent magnet.The chassis that is provided with electromagnet constitutes the magnetic force base, and it utilizes electromagnetic induction principle, and electromagnet energising back permanent magnet drives button and is suspended in surface of keyboard.When the finger presses keyboard, the relative distance of permanent magnet and electromagnet reduces, and it is big that the magnetic field intensity of electromagnet becomes, and the key induced coil that electromagnet is provided with outward will produce a signal of telecommunication, and this electrical signal transfer is finished instruction to controller.Otherwise when finger left keyboard, permanent magnet resetted under situation about not being under pressure, and it is big that the relative distance of permanent magnet and electromagnet becomes, and makes circuit produce another signal of telecommunication, order fulfillment behind the controller acknowledge(ment) signal.The upper and lower motion of the button of magnetic suspension keyboard is soft, and noise is little; Button is combined closely with cover cap, is difficult for falling into particulate matter, also is convenient to clean.The regulating winding electric current can be adjusted button suspension dynamics, and is not only easy to use, and is conducive to realize the personal settings of keyboard.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model button assembling schematic diagram.
Embodiment
With reference to accompanying drawing, the utility model comprises chassis 1, chassis 1 is provided with the electromagnet 3 corresponding with keyboard 4, and electromagnet 3 is outer can be respectively equipped with a magnetic coil 32 and key induced coil 33, also magnetic coil 32 and key induced coil 33 can be merged into a coil.Preferably magnetic coil 32 and key induced coil 33 are merged into a coil, this coil is connected with electromagnet 3 current supply circuits with the push button signalling loop.The iron core 31 of electromagnet 3 adopts iron-nickel alloy to make, and coil is silver-gilt copper wire.Chassis 1 is provided with the cover cap 2 of living and connecting with it, and cover cap 2 is provided with some key chambeies 21 that can hold electromagnet 3, and these 21 tops, key chamber also are provided with keyhole 22.Button 4 is the cap shape, and its lower end and key chamber 21 inwalls slide and join, and the upper end passes keyhole 22, and button 4 can axially be done upper and lower moving along key chamber 21, and button 4 lower ends are limited by the keyhole wall, and it can not deviate from from keyhole 22.Button 4 tops are provided with iron nickel cobalt set magnet permanent body 41, and after electromagnet 3 energisings, permanent magnet 41 is subjected to the effect of magnetic force to drive button 4 and is suspended in electromagnet 3 tops.
Each function key of the present utility model is made up of electromagnet and the button of mutual correspondence, and button is provided with permanent magnet.The chassis that is provided with electromagnet constitutes the magnetic force base, and it utilizes electromagnetic induction principle, and electromagnet energising back permanent magnet drives button and is suspended in surface of keyboard.When the finger presses keyboard, the relative distance of permanent magnet and electromagnet reduces, and it is big that the magnetic field intensity of electromagnet becomes, and the key induced coil that electromagnet is provided with outward will produce a signal of telecommunication, and this electrical signal transfer is finished instruction to controller.Otherwise when finger left keyboard, permanent magnet resetted under situation about not being under pressure, and it is big that the relative distance of permanent magnet and electromagnet becomes, and makes circuit produce another signal of telecommunication, order fulfillment behind the controller acknowledge(ment) signal.The upper and lower motion of the button of magnetic suspension keyboard is soft, and noise is little; Button is combined closely with cover cap, is difficult for falling into particulate matter, also is convenient to clean.The regulating winding electric current can be adjusted button suspension dynamics, and is not only easy to use, and is conducive to realize the personal settings of keyboard.
