Abstract
The utility model relates to an electrical swaying bed, which consists of a swaying bed, a supporting frame, a pendulum axle, a motor and a controlling device. A signal output by a signal generator is output after being amplified by an amplifying circuit, and the signal generator is connected with the motor after being photoelectrically coupled, so as to drive the motor to sway. The utility model has the advantages that the swaying is flexible and stable, and the amplitude of the swaying is adjustable. The utility model can be used on the swaying bed, and can also be used on other devices needing the swaying, such as a rocking chair.
Description
Affiliated technical field
The utility model relates to a kind of motor-driven electric cradle.
Background technology
At present, electric cradle is of a great variety, and structure has nothing in common with each other, if any be motor-driven, have for magnet drives.The weak point of its existence is, is subject to the influence of angle position during swing, and the amplitude of oscillation is difficult for regulating.
Its purpose of the utility model just is to provide a kind of angle position that is not subjected to influence, and the adjustable electric cradle of the amplitude of oscillation.
Summary of the invention
The technical scheme that realizes above-mentioned purpose and adopt comprises, is made up of shaking table, support, balance staff, motor and control system, and the signal generator also is installed in the balance staff end, and the signal generator is exported through V
1～V
4The amplifying circuit output of forming connects motor D through photoelectric coupling MOC
2, motor D
2One termination civil power, the other end connects city's machine through inductance L and temperature control t °.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing,
Fig. 1 is this apparatus control system electrical schematic diagram;
Fig. 2 is this apparatus structure schematic diagram.
The specific embodiment
Example structure comprises, electric cradle is made up of shaking table 5, support 4, balance staff 2, motor 3 and control system, in balance staff 2 ends signal generator 1 is installed also, signal generator D
1Output is through V
1～V
4The amplifying circuit output of forming connects motor D through photoelectric coupling MOC
2, motor D
2One termination civil power, the other end connects city's machine through inductance L and temperature control t °.
Its operation principle is as follows, sees Fig. 1.
The power-on switch, circuit enters SBR, promotes shaking table arbitrarily or clicks starting switch (having among the figure slightly) with hand, and the motor 3 and the signal generator 1 that at this moment are installed on the balance staff 2 are driven, if just be the positive direction swing, signal generator D
1Promptly export the positive voltage about 0.6V, this signal voltage is through V
1～V
4Amplify back output, photoelectric coupling MOC conducting, shaking table starter motor D
2Energising work drives shaking table and continues to be flapped toward peak.Work as motor D
2When power equaled shaking table weight, shaking table stopped to rise, at this moment signal generator D
1Quit work no signal output, shaking table starter motor D
2Lose power supply, the backhaul on own wt and action of inertia are got down from horse of moment shaking table is put in the other direction to peak, in the backhaul process, and the counter-rotating of signal generator, the output negative voltage, amplifying circuit does not receive, V
1Be in cut-off state, shaking table starter motor D
2Can not get power supply and do not work (increase oscillating quantity if desired, can refill a same signal controlling plate, make starter motor energising work when backhaul), when treating that next shaking table positive direction is swung, control circuit work goes round and begins again.In brief, positive direction is swung the strength that relies on starter motor, and swing in the other direction is high certainly to low own wt and action of inertia by shaking table.
Because signal generator, shaking table starter motor and shaking table turning cylinder coexist on the axle, so signal polarity, the shaking table starter motor need be switched on can keep synchronously consistent forever with power-off time.
This swing system not only can be used for also can be used for other occasions that need wave such as rocking chair on the shaking table.Compared with prior art this device has the following advantages,
1, because this device has adopted signal generator, photoelectric coupling and starter motor dispatch control system, thus have control flexibly, working stability, reliable characteristics.
2, regulate the design of the amplitude of oscillation owing to having adopted in the control system, thereby have the function of regulating rocking tendency.
