Abstract

The utility model relates to an automatic rocking bed for babies, composed of a bed body, a base and a control circuit. The bed body is connected with the base through a spring; the bed body is in a suspension state; the corresponding positions of the center of the bed body and the base are respectively provided with inductance coils; each inductance coil is provided with an iron core; when the two inductance coils receive direct current of opposite polarity simultaneously, attractive force is generated on the iron cores to cause the bed body to sink; when the current disappears, the bed body is held up again. The utility model overcomes the form of side-to-side swinging designed by an existing rocking bed and adopts the method of vibrating up and down, which is favorable for the hypnogenesis of the babies consequently. The utility model has the advantages of smaller noise, less power consumption and simple structure.

Description

Baby automatic rocking bed

The utility model relates to a kind of automatic shaking table for baby's use.

Can the infantile most of the time be spent in bed, obtain suitable bed, and normal development of baby's health and intellectual development are had material impact.The automatic shaking table design of the baby of present domestic appearance, its main feature is to make electromagnet obtain the pulsed operation electric current by the acoustic control control circuit, the swing of driving shaking table, structurally all be to adopt swing structure, there is following shortcoming in these shaking tables: swing structure requires control circuit accurately to locate, also require to have simultaneously to detect and synchro system, therefore make circuit complicated, cause probability of malfunction to raise and the manufacturing cost rising, the bed body of swing structure is because the restriction of driving magnetic field power in addition, the amplitude of bed body swing is very limited, the weak effect that up-down vibration produced in its hypnotic effect is held in the arms than similar as mother.

The purpose of this utility model is to provide a kind of energy upper and lower vibration by the setting of design of lathe bed suspension structure and inductance coil etc., and circuit structure simply has the automatic shaking table of baby of multiple function.

The purpose of this utility model is achieved in that by lathe bed, base and control circuit and constitutes, its structural feature is: the automatic shaking table of lathe bed baby and base are connected by spring by means of spring hanger separately, make lathe bed be in suspended state, the lathe bed bottom is equipped with an inductance coil, also there is an inductance coil base center, the iron core that one one end is fixed on the lathe bed bottom is inserted at the middle part of two inductance coils, a hole that allows iron core to move up and down is arranged on the pairing position base of the other end of iron core, iron core can the inductance coil on base in easy on and off move; The voice signal that is received by pick-up head EJ in control circuit starts timing circuit after sound control circuit amplifies rectification, the output termination oscillating circuit of timing circuit, and drive circuit is connected on the output of oscillating circuit, and two inductance coils connect the output of drive circuit.

The utility model has the advantages that up-down vibration is steady, noise is very little, power consumptive province, simple in structure, therefore good to baby's hypnotic effect, help growing of baby, in addition, circuit part of the present utility model requires not meticulous, need not accurate location, therefore makes simple.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the utility model overall structure figure.

Fig. 2 is an electrical schematic diagram.

The utility model bed structure comprises lathe bed (1), base (2), electric appliance control box (10), spring all is equipped with in four hollow pipes (4) inside below lathe bed (1), its port of export all has clip (5) to tie up to spring end, clip (5) can be clamped four jiaos of quilt, can prevent that the baby from kicking quilt off, between lathe bed (1) and the base (2) by means of separately spring hanger (3), (8) connect by spring (11), lathe bed (1) is in suspended state, lathe bed (1) bottom is equipped with inductance coil L1(6), also there is an inductance coil L2(9 base (2) center), two inductance coil L1(6), L2(9) iron core (7) that one one end is fixed on lathe bed (1) bottom is inserted at center, and a hole that allows iron core (7) to move up and down is arranged on the pairing base of the other end (2) position of iron core (7).As upper and lower two electrically-heated coil L1(6), when L2(9) from drive circuit, obtaining opposite polarity direct current simultaneously, go up generation suction at iron core (7), iron core moves downward the sinking of drive lathe bed by the hole at L2 center, at this moment, spring (11) is attracted, after electric current disconnected, suction disappeared, and the restoring force of spring holds up lathe bed (1) again, when primary current comes instantly, repeat said process again.

Control circuit of the present utility model is by sound control circuit, timing circuit, and oscillating circuit and drive circuit are formed.

Concrete working condition of the present utility model is as follows:

In circuit diagram 2, form sound control circuit by pick-up head EJ, transistor BG1, BG2, crystal diode D1, D2, timing circuit is made up of NE555, BG4,3DG6 and resistance R 4, capacitor C 4, wherein time delay is by the time constant decision of R4, C4, oscillating circuit is by NE555, potentiometer W, resistance R 5, capacitor C 5 is formed, and drive circuit is made up of BG4,3DD15.

When baby crying, the signal that pick-up head EJ picks up behind diode D1, D2, voltage multiplying rectifier, makes the BG2 conducting after BG1 amplifies, and C4 institute charging voltage discharges IC rapidly in the timing circuit through BG2 ₁3 pin are in high level at this moment, the BG3 conducting, and oscillating circuit is powered up work, IC ₂Output one impulse waveform in 3 pin, its high level will make the BG conducting, and L1, L2 establish electricity, produce suction on iron core, and its low level will make 4 to end, L1, L2 dead electricity, suction disappears, as mistake time delay one, IC ₁3 pin are converted to low level, and BG3 ends, and the oscillating circuit dead electricity quits work.The operating voltage of entire circuit is decided to be 30V, by sending into control circuit again behind the 220V alternating current step-down rectifier.
