Embodiment
As shown in Figure 1, both sides of the present utility model are respectively equipped with S magnetic pole 7 and N magnetic pole 6; Each button 3 is all in the magnetic field in two magnetic poles; The latter half of each button 3 is all tied with conductive coil 12, the two ends of conductive coil 12 respectively by interchange input positive bus 1, exchange input negative bus 2 access energy storage 9; The gap of each button 3 inside is provided with light emitting diode 11 and exports both positive and negative polarity 4 by direct current and is connected to energy storage 9.
The conductive coil 12 of each button 3 is all arranged at the top of elasticity keycap 13.Energy storage 9 is arranged near of keyboard power line 5.Between the conductive coil 12 of each button 3, it is parallel-connection structure; It between the light emitting diode 11 of each button 3, is also parallel-connection structure.
Between energy storage 9 and conductive coil 12, be provided with rectification circuit 8.Between energy storage 9 and light emitting diode 11, be provided with voltage stabilizer 10.And the outward appearance of button 3 is used transparent material, and the character of button is presented to characters cut in relief, makes the character on keyboard more clear.
The utility model is as an independent entirety in the process that realizes expection lighting function, and main frame does not contact.Common keyboard is divided into button, upper cover plate and is embedded in each button wherein.Below upper cover plate, it is a rubber film, under the position of each button, there is an elasticity keycap, these parts are exactly the main flexible member of keyboard, below rubber film, three plies plastic sheetings together, the upper and lower two-layer film wire that is covered with, a middle plastic sheeting is not contain any wire.The utility model is mainly transformed between the elasticity keycap 13 of common keyboard and button 3, makes, in magnetic field that keyboard produces in both sides opposite pole, by electromagnetic induction principle, the mechanical energy pushing button to be converted into the luminous electric energy of light emitting diode 11 at 3 o'clock.The light that light emitting diode 11 sends produces soft light by the button 3 after improving.The luminous of light emitting diode 11 can be controlled artificially by switch, and play the electrical power storage of generation to be used as the required electric energy of glowing at night element daytime.Can allow people at the bad local operation keyboard of light compared with common keyboard, save electricity consumption, reduce the injury of light to eye simultaneously.
By electromagnetic induction principle, when being placed on conductor in magnetic field and doing cutting magnetic induction line motion, its two ends can produce electromotive force.First common keyboard is improved, place opposite pole at its two ends, thereby make whole button 3 all in this magnetic field.Electric energy accumulator 9 is fixed near the position of keyboard power line 5.
Each button 3 is improved, in its latter half, is tied with conductive coil 12, the two ends of conductive coil 12 by interchange input positive bus 1, exchange input negative bus 2 be connected with energy storage 9 the two poles of the earth.Each light emitting diode 11 is placed on the internal voids place of each button 3, is connected with energy storage 9 by direct current output bus 4.
In the time that keyboard is worked, conductive coil 12 can cut its magnetic field around up and down, produces electromotive force.The conductive coil 12 being wound around under keyboard produces electromotive force by being connected with the both positive and negative polarity of energy storage 9 respectively in the time of its cutting magnetic induction line, so no matter to press which button and all can charge to it.The electric energy that on button 3, coil cutting magnetic field produces is faint, utilizes a larger capacitive energy storage device 9 just can complete the collection of electric energy.In the time that the direction of motion of button 3 is different, the direction of current that coil cutting magnetic field produces also can be contrary, can make it to the electric discharge of charging limit, storer limit, lowered the efficiency of energy storage.Add a rectification circuit 8 at accumulator input end for this reason, improve the efficiency of collecting electric energy.Because the motion process medium velocity of button 3 is different, the voltage swing of generation is also different, in order to prevent that light emitting diode 11 is burned, and has increased voltage stabilizer 10 at its input end.In the time that switch is closed, energy storage 9 starts all light emitting diodes 11 of parallel connection to power, and has realized conducting simultaneously, thereby can very clearly see the numeral on keyboard.The electric energy that button 3 produces simultaneously continues energy storage 9 to charge, like this until complete power consumption light emitting diode 11 just can be stopped luminous.And by the coil turn twining under the each button of calculative determination, guarantee that the electric energy often producing by one-touch can maintain the 11 bright several seconds of lamp of all light emitting diodes under keyboard by energy storage 9.The switch that only need to disconnect energy storage 9 in the time of end-of-job just can disconnect circuit, and light emitting diode 11 is just no longer luminous.
The utility model is reducing because under the prerequisite that computer screen luminance difference is damaged eye, and saves energy, improves the efficiency of people's work.The keyboard appearance that it is transparent, makes the character on keyboard more clear.Fully effectively utilize the advantage of light emitting diode 11, make it bring considerable benefit to us.Because light emitting diode 11 and conductive coil 12 are dirt cheap, therefore only need spend more sub-fraction money and just can buy and integrate keyboard attractive in appearance healthy and that economize on electricity.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
