Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Power module is made up of mechanical part and rectifying and voltage-stabilizing part.
With reference to Fig. 1, the first half of mechanical part and the latter half structural similarity.Example is divided into Lower Half, with reference to Fig. 3, the switch key 15 comprising lower inductance coil 18, be inserted in the lower permanent magnet 19 of lower inductance coil 18 li, lower permanent magnet 19 can be driven to move together.
With reference to Fig. 1, the actuating mechanism at permanent magnet and switch key place, adopts recorder button principle.Permanent magnet is bar-shaped, and is provided with stopper.Following permanent magnet 19 is example.
As shown in Figure 3, lower stopper 110 is arranged at bar-shaped lower permanent magnet 19 top.Lower sleeve 111 li is equipped with inductance coil 18 and spring 112.Inductance coil 18 is connected to rectifying and voltage-stabilizing part.Be inserted with lower permanent magnet 19 inside inductance coil 18, spring 112 is positioned at below lower permanent magnet 19.Upper bush 113 li has same structure.
As Fig. 1, switch key 15 props up lower permanent magnet 19 and upper permanent magnet 114 respectively around the two ends that rotating shaft 14 is rotated.Trace 116 is had between lower permanent magnet 19 and upper permanent magnet 114.The bottom of switch pedestal 13 is fixed with trace support 117, and trace 116 is fixed on trace support 117, can above below slide.Spring 118 is equipped with in the upside of trace 116.The other end of spring 118 is connected on the upside of switch pedestal 13, tension trace 116.Lower permanent magnet 19, under the pressure of spring 112, has the trend moved upward.But because lower stopper 110 is subject to the stop of trace 116, lower permanent magnet 19 keeps inactive state.
Push switch button 15, in compressing, permanent magnet 114 moves downward, and upper stopper 115 is oppressed trace 116 and moved downward.Descend stopper 110 no longer to contact with switch key 15 simultaneously.When trace 116 moves to certain position, lower stopper 110 shakes off trace 116, fast upward motion under spring 112 elastic force.Cause changes of magnetic field at the volley, inductance coil 18 responds to generating.
Upper stopper 115 moves to below trace 116 under pressure, and trace 116, under the pulling force of the spring 118 be connected on trace 116, moves upward.After loosing one's grip, upper permanent magnet 114 is under the pressure of spring 118, has the trend moved upward.But because upper stopper 115 is subject to the stop of trace 116, upper permanent magnet 114 keeps inactive state.
Push switch button 15 again, the lower permanent magnet 19 of compressing moves downward, and lower stopper 110 is oppressed trace 116 and moved downward.Go up stopper 115 no longer to contact with switch key 15 simultaneously.When trace 116 moves to certain position, under upper stopper 115 spring force below, shake off trace 116, fast upward motion.Cause changes of magnetic field at the volley, inductance coil induction generating.
Lower stopper 110 moves to below trace 116 under pressure, and trace 116, under the pulling force of the spring 118 be connected on trace 116, moves upward.After loosing one's grip, lower permanent magnet 19 is under the pressure of spring 112, has the trend moved upward.But because lower stopper 110 is subject to the stop of trace 116, lower permanent magnet 19 keeps inactive state.Again return to primary state.
Each Push switch button 15 all can send electric energy, and flows to rectifying and voltage-stabilizing part.Signal emission module 12 is flowed to after over commutation and voltage stabilizing.
See figures.1.and.2, the mobile fixing electric lamp switch of this power module is adopted to comprise switching device 1 and electric lamp control device 2, switching device 1 comprises switch housing 11, signal emission module 12, power module, and electric lamp control device 2 comprises control device shell 21, signal receiving module 22, switch control module 23.
As Fig. 1, the similar button light switch with commonly using of described switch housing 11 profile, have switch pedestal 13, switch pedestal 13 is by rotating shaft 14 connecting valve button 15.
Switch pedestal 13 li is equipped with power module, signal emission module 12, and top is provided with light inlet window 16, and signal emission module 12 connects light-emitting component, and light-emitting component is positioned at (not shown in FIG.) after light inlet window 16, and light signal is transmitted into the external world by light inlet window 16.It is the plane for bonding double faced adhesive tape 17 after switch pedestal 13.After being stained with double faced adhesive tape 17, can be fixing in place by double faced adhesive tape 17.
As Fig. 2, the control device shell 21 of electric lamp control device 2 is similar to now conventional multiplex socket shell.Top is the joint 24 be connected with existing socket, and bottom is circuit part shell 25, is sub-socket 26 in the middle part of circuit part shell 25.Signal receiving module 22 and switch control module 23 are housed in the space between circuit part shell 25 and sub-socket 26.Sub-socket 26 connects lamp power supply by switch control module 23, and sub-socket 26 connects electric light.
Described signal receiving module 22 connects phototriode 27.Phototriode 27 has three, is evenly arranged in around below control device shell 21, is convenient to the light signal that reception all directions transmit.
The light signal received is changed into the signal of telecommunication by phototriode 27, passes to signal receiving module 22.Analyzed by signal receiving module 22 pairs of signals, determine the signal whether assigned switch device 1 is sent.If it is output signal to switch control module 23, controlled the switch of electric light by switch control module 23.
Often press one-touch switch 15, controlled electrical equipment conversion once controlled state.
Electromagnetic induction device adopts just slightly improving on the basis of said structure with the execution mode of link gear of small generator.Therefore do simply to illustrate mechanical part based on said structure, lower permanent magnet 19 and upper permanent magnet 114 need not use magnetic material again, only as mechanical structure, their upside the first half installs tooth bar additional, article two, tooth bar respectively with two gears meshing, two gears connect two link gears respectively, and two link gears connect a small generator respectively.Link gear can be extremely simple, is only made up of the rotating shaft of the small generator be fixed on gear.Inductance coil in lower sleeve 111 and upper bush also can remove.
Small generator is fixed on switch housing 11, the rotating shaft of small generator is equipped with the heavier flying wheel centered by rotating shaft.
Use hour rack to drive small generator generating by link gear, drive the flying wheel in rotating shaft to rotate simultaneously.Due to the parts that there is same structure with lower permanent magnet 19 and upper permanent magnet 114 tooth bar that only had the first half to install additional, when switch key 15 is almost fully upspring, gear no longer engages with tooth bar, and rotating shaft is rotated further under the drive of flying wheel, and small generator continues generating.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
