Abstract
The utility model relates to a solenoid drive, in particular to a cradle solenoid drive, which comprises permanent magnet steels, an electromagnet, a sensor and a control circuit. Wherein, the sensor provides position signal and enables the electromagnet to create magnetic field with the control circuit. In addition, the drive is provided with a permanent magnet cradle frame to realize repeated moving. The utility model has the advantages of simple structure, strong drive capacity, reliable operation and no noise and can be applied to cradle, rocking chair, rocking bed and mechanisms with repeated moving as an actuating device.
Description
One, technical field:
The utility model relates to a kind of cradle magnetic driven device that is driven the cradle swing by the magnetic field interaction of permanent-magnet steel and electromagnet.
Two, background technology:
Cradle in the market has and manually shakes, and has motor to drive by reducing gear, and the former simply takes the labour, and the latter is complicated that noise is big.
The purpose of this utility model provides a kind of simple in structure, noiselessness cradle magnetic driven device.
Three, summary of the invention:
The technical solution of the utility model is: a kind of magnetic driven device, particularly a kind of cradle magnetic driven device, form by permanent-magnet steel, electromagnet, transducer and control circuit, it is characterized in that: permanent-magnet steel places on the swinging mounting of cradle, electromagnet places on the relevant position of the stationary base mount below the cradle swinging mounting, relative and the certain angle that staggers of the two polarity, transducer places on the stationary base mount of cradle, and is corresponding with the terminal point of permanent-magnet steel motion.Described electromagnet is a kind of interrupted energising DC electromagnet; Control circuit duty ratio is on demand powered to solenoid.
Transducer of the present utility model is exactly a tongue tube.
Control circuit of the present utility model is a controllable silicon half control rectifier circuit.
When permanent-magnet steel swung near tongue tube, under the effect of permanent-magnet steel magnetic force, the closed silicon controlled circuits for triggering of connecting of tongue tube triggered and supply solenoid rectified current controllable silicon; So electromagnet produces a stationary magnetic field, the magnetic interaction of this magnetic field force and permanent-magnet steel and drive cradle support motion, when permanent-magnet steel is put from tongue tube, tongue tube is opened a way and is disconnected silicon controlled triggering loop and make the solenoid outage, electromagnetic force disappears immediately, thereby cradle puts again by inertia force, and permanent-magnet steel is once more near tongue tube, the solenoid generation electromagnetic force of switching on again drives the swing that cradle support goes round and begins again like this.
Four, description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is an electrical schematic diagram.
Among the figure: 1, swinging mounting; 2, permanent-magnet steel; 3, electromagnet; 4, circuit board; 5, transducer.
Five, embodiment:
As shown in Figure 1, the utility model is made up of permanent-magnet steel 2, electromagnet 3, transducer 5 and control circuit 4.Permanent-magnet steel 2 places on the swinging mounting 1 of cradle; Electromagnet places on the pedestal of cradle, and the two polarity is strict relatively and at interval to be determined by designing requirement; Transducer places on the corresponding position of terminal point of swinging with permanent-magnet steel on the pedestal, and receives on the control circuit with two leads.
After starting the cradle swinging mounting, permanent-magnet steel 2 proximity transducers 5 are under the permanent-magnet steel the action of a magnetic field, the sensor contact closure, draw in generation magnetic field or the swinging mounting of thrust drive permanent-magnet steel through circuit board control electromagnet to be switched on, make it backward or preceding swing, permanent-magnet steel leaves transducer gradually like this, and being disconnected, its contact causes the electromagnet outage, magnetic field disappears, so swinging mounting commutates under the inertia force effect and advances or retreat and near transducer, the swing that like this goes round and begins again, the polarity in two kinds of magnetic fields can be that the same sex is relative, also the opposite sex is relative, but corresponding adjustment should be followed in the position of transducer.
Control circuit is made up of half control full-bridge circuit and trigger as shown in Figure 2, and wherein trigger is exactly a transducer a---tongue tube, thereby simple in structure, and antijamming capability is strong.
The utility model power is magnetic field force, does not have machinery conversion power and complicated transmission mechanism, and is simple in structure, noiseless, and cost is low, and is convenient for installation and maintenance, can be widely used in cradle, rocking chair, shaking table and other reciprocating mechanism and make drive unit.
