The electromagnetism switching device shifter of wabbler mechanism

Technical field

The utility model is that a kind of simple electromagnetism of no hot-tempered sound, safe, power saving and circuit structure design that is applied in automaticallyes switch and feedbacks control wabbler mechanism device; Be meant especially and a kind ofly move and produce the minus phase induced current that positive phase induced current (this moment control circuit in the whole conductings of transistor) and mutual inductance produce (this moment control circuit in transistor Close All), and then whether feedback according to transistorized conducting that to control rocking equipment be to wave or stop to wave in the induction of base induction coil by waving of the magnetic devices (as magnet) that is fixedly arranged on wabbler mechanism bottom.

Background technology

Known electric rocking chair or electric swinging device such as electric cradle known to general all is with motor transmission control, and progressive then have the control circuit that utilizes the alternating current input to feedback the control device of controlling mechanism; As adopt the direct transmission control of motor owing to there is hot-tempered sound big, control is difficult for, disappearances such as misgivings and power consumption on the safety of big electric current, big voltage etc.; Have then that the safety problem of coil and control circuit are complicated can't to be reached efficient power saving and can't use disappearance such as DC power supply because of alternating current burns if utilize the control circuit of alternating current input to feedback the control device of controlling mechanism.

Summary of the invention

Therefore based on the disappearance of above-mentioned known techniques, main purpose of the present utility model is that back coupling mechanism by the induction mechanism of magnet and coil and control circuit is to reach no hot-tempered sound control system rocking equipment.

The secondary objective of this case is by the control of the back coupling of the induction mechanism of magnet and coil and control circuit mechanism, make rocking equipment start or to stop be mobile according to waving of magnet, improved the fail safe on rocking equipment uses greatly.

A purpose again of this case is power saving, because whether transistorized conducting all is associated with moving of magnet in the control circuit, improved power consumption efficiency greatly, so the utility model can reach purpose of power saving, also because the utility model power consumption is very low, therefore control circuit of the present utility model can directly use the input power supply of battery DC power supply as control circuit.

Based on above creation purpose, for reach no hot-tempered sound, safety is considered and the preceding topic of power saving, the special the utility model that proposes; The utility model is a kind of electromagnetism switching device shifter of wabbler mechanism, comprising: a wabbler mechanism; One magnetic devices is the bottom of being fixed in this wabbler mechanism; One coil is to correspond to this magnetic devices to produce electric current with induction; And a control circuit, be to feedback the start of this wabbler mechanism of control to control this control circuit by the electric current of generation that this coil is responded to.

Wherein this wabbler mechanism is to can be rocking equipments such as general rocking chair or shaking table.

This magnetic devices is to can be a magnet that includes the N utmost point and the S utmost point.

This coil is for comprising the loading coil of an induction faradic induction coil of positive phase and an induction minus phase load current.

This induction coil is by the mobile induction one positive phase electric current of this magnetic devices so that the transistor turns of this control circuit and then this wabbler mechanism start (ON) of back coupling control.

This loading coil is by the transistor turns electric current and mutual inductance to this induction coil responds to a minus phase electric current so that the transistor of this control circuit is closed and then feedback control this not start of wabbler mechanism (OFF).

This control circuit be by the positive phase induced current of this induction coil and generation that this loading coil is responded to and minus phase load current controlling the transistor turns in this control circuit or to close, and then feedback control this wabbler mechanism start or not start

The automatic control equipment of the wabbler mechanism that the utility model is mentioned is improved the control of the direct motor of known tradition and is adopted automatic back coupling controlling mechanism, simultaneously, also have and feedback control with at present progressive on the market control circuit and must use AC input and have the disappearance of burning misgivings and control circuit complexity to be improved, and have or not hot-tempered sound, safe, power saving and the simple advantage of circuit design.

Embodiment

Please refer to Fig. 1, this figure is a diagram system architecture block schematic diagram of the present utility model, as shown, because power consumption of the present utility model is very little, so this case system can use the DC power supply 5 of battery as the input power supply, this DC power supply 5 starts wabbler mechanism 1 of the present utility model and control circuit 4 work, the magnetic devices 3 that drives its bottom when this wabbler mechanism 1 waves waves, the coils 2 that are fixed in the native system base 6 along with the mobile induction of waving of this magnetic devices 3 produce the induced current of positive phases and the mutual inductance electric current of minus phase, and when induction produces the induced current of positive phase, making whole conductings of transistor in this control circuit 4, this control circuit 4 was feedback and was controlled these wabbler mechanisms 1 and continue to wave this moment; This magnetic devices 3 stops to wave mobile when this wabbler mechanism 1 experience hinders then, this moment, this coil 2 did not produce induced current, make the transistors in this control circuit 4 not have conducting, this control circuit 4 feedback these wabbler mechanisms 1 of control and stopped to wave (also can use directly cut out DC power supply 5 make this wabbler mechanism 1 stop to wave) this moment.

Please refer to Fig. 2, this figure is the circuit diagram of control circuit 4 of the present utility model, the input power supply of control circuit 4 of the present utility model is to can be 6-7.5V battery DC power supply 5, this battery DC power supply 5 can be done manual switchover by power change-over switch 43, and shows the current battery power condition with power supply indicator 44 (green light-emitting diode); Transistor 41 then when the induction coil between white line-black line induction positive phase induced current, transistor 42 whole conductings, the control circuit 4 of this case this moment system is feedback and is controlled the wabbler mechanism work done, relay indicating light 45 (red light-emitting diode) shows the wabbler mechanism start, transistor 41 then when loading coil between red line-black line 21 produces the induced current of minus phases by electric current and mutual inductance induction coil 22, transistor 42 Close Alls, this moment, the control circuit 4 of this case system was feedback the not works done of control wabbler mechanism, relay indicating light 45 (red light-emitting diode) display lamp go out (wherein this power switch adjust button 46 can be used to adjust the power that transistor opens and closes).
