Description

Full automatic magnetic-driving energy-saving cradle

The utility model belongs to a kind of daily necessities.

Existing shaking table is made of bed body and motor and transmission device that a body is shaken, promptly with driven by motor bed body it is rocked.The shortcoming of this electric cradle is that power consumption is more, and noise is arranged.In order to overcome the shortcoming of electric cradle, designed the energy-conservation shaking table of full-automatic magnetomotive of the present utility model.

Structure of the present utility model mainly is divided into a body, support or circular arc type leg, contain four parts such as the electromagnet of iron core and control device, said support cooperates with lifting rope and is used for suspension bed body, or with circular arc type leg support bed body, two permanent magnets are installed below the bottom of bed body, are contained the electromagnet direct current supply of iron core, be fixedly mounted in the middle of two permanent magnets in body below.Controller is used to change the sense of current of electromagnet power supply, and said control device can be that photogate and controller constitute, sense of current in photogate and the controller control electromagnet; Also can be by automatic frequency controller directly by the frequency shift sense of current close with the natural frequency of bed body, the electromagnet supplier of electricity produces attraction and repulsive force to two permanent magnets respectively when changing, a body is shaken.

Fig. 1 is a structural representation of the present utility model.Among Fig. 1,1 is support, and 2 is lifting rope, and 3 is the bed body, and 4 is permanent magnet, and 5 is light barrier, and 6 is photogate, and 7 is electromagnet, and 8 is controller, and 9 is power line.

It is indoor that support 1 can be that a cross bar is fixed in, and by lifting rope 23 suspentions of bed body got up, so that a bed body 3 shakes.Support 1 also can be two cross bar secured in parallel, make to shake and be bordering on translation (dotted line among Fig. 1), also available circular arc type leg replaces support 1, take up room with minimizing, and produce different effects, can also do appropriate change, be designed to automatic easy chair automatic swing etc., when making automatic swing, as long as lifting rope 2 is longer, bed body 3 is made a stool formula, permanent magnet 4 is installed below bed body 3, two permanent magnets 4 are individually fixed in the two ends of a body 3, like pole is staggered relatively, light barrier 5 is fixed in the bottom of a body 3, light barrier 5, photogate, 6 and controller 8 constitute control device, be used for controlling the sense of current of electromagnet 7, thereby change the pole orientation of electromagnet, controller 8 is mainly by voltage regulator, rectifier power source, constituted by the circuit of the change sense of current of photogate 6 controls, photogate 6 mainly is made of luminous tube and receiver, and the two installs dress relatively, and electrically connects with controller 8, light barrier 5 can obstruct the light between luminous tube and receiver, light barrier 5 with the every retaining of light between luminous tube and receiver once, the sense of current of controller 8 changes once, power line 9 is connected 220V, the interchange of 50Hz, electric via controller 8 rectifications are electromagnet 7 power supplies.

Connect civil power when power line 9, electromagnet 7 begins to have direct current to pass through, and the electromagnetic field that electromagnet 7 produces produces attraction to a permanent magnet 4, and another piece permanent magnet 4 is produced repulsive force, makes a body 3 depart from the equilbrium position and begins to shake.When putting certain position, photogate 6 conductings, current reversal, gravity and magneticaction make a body moving to backswing, behind the pendulum overbalance position, reach inertia and make a body continue swing forward under magneticaction, when photogate 6 conducting once more, electric current is reverse again, a body 3 is swung continuously, suitably regulate the width of light barrier 5, the voltage regulator in the conditioning controller 8 can be regulated amplitude of oscillation size continuously.

Fig. 2 is a power schematic diagram of the present utility model, having marked the magnetic polarity orientation of permanent magnet 4 and the sense of current of electromagnet 7 among Fig. 2 changes, Fig. 3 is the structural representation of change electromagnet 7 senses of current of the present utility model, among Fig. 3,5 is light barrier, 10 is luminous tube, and 11 is receiver, and 12 is the bed end, a is the light that light barrier 5 covers 11 of luminous tube 10 and receivers, to be light barrier 5 tilt to remove between luminous tube 10 and the receiver 11 to an end with 12 swing at the bottom of the bed b, makes photogate 6 conductings, and electric current is made as forward, then c is that light barrier 12 shakes at the bottom of with bed, tilt to the other end, during the photoelectric tube conducting, current reversal.

The utility model also can add following several function:

(1) sound-controlled apparatus: open audio-switch, when the baby cried, bed body 3 can begin to wave (2) timing device automatically: set certain waving the time, by clock control, regularly open regularly and close (3) remote control: as the remote-control switch and the amplitude of oscillation.

The utility model has following characteristics:

(1) energy-conservation: attraction and the repulsive force of selecting for use permanent magnet and electromagnet to produce are used as power, and especially select rare-earth permanent magnet for use, can save energy greatly.(2) comfortable, steady: owing to be contactless power, there is not friction, friction, noiseless, switch, starting can be automatic.When selecting photogate control for use, its forced frequency is exactly the natural frequency of a body, therefore, and steady, the nature of swing.(3) health care: the magnetic field that permanent magnet and electromagnet produce has certain Magnetotherapeutic health and syngignoscism, (4) be suitable for producing: because the utility model is suitable for family, the kindergarten does shaking table, swing use for infant and children, and is simple in structure, with low cost, thereby be suitable for producing.
