Abstract

The utility model relates to an electromagnetic driving rocking bed which has a controlling circuit and a driving electromagnet arranged on a swing bed frame, and has a driving permanent magnet arranged on a movable bed board compared with the prior rocking bed. The permanent magnet is controlled by sound to start rocking and stop rocking the bed timely.

Description

Electromagnetic driving rocking bed

The utility model relates to a kind of rocking equipment of Electromagnetic Drive, when being particularly suitable for lying fallow and the baby use.

At present, known rocking bed is to use manually driven, brings inconvenience to the user.

The purpose of this utility model provides a kind of Electromagnetic driving rocking bed, to remedy the deficiency that manpower drives shaking table.

The purpose of this utility model is achieved in that between shaking table framework and bed board, the rocking arm of four parallel to each other and equal in length connects by axle with rocker arm support, make the bed board activity freely, center fixation one cylindrical permanent magnet in the bed board bottom surface, its planar section is corresponding with the end face of the DM of below, when DM is logical when going up direct current, can produce the magnetic field of a fixed magnetic pole on its iron core end face, repel each other with the magnetic field of its top permanent magnet opposed, produce a thrust, bed board is removed, this moment, control circuit made the electromagnet outage, and bed board resets and be mobile in the other direction under gravity and effect of inertia, and control circuit gets electromagnet simultaneously, the iron core end face produces a magnetic field again, moves a thrust for the opposite direction of bed board; Go round and begin again like this, reach the purpose that bed board is back and forth waved.Designed in circuit in addition that acoustic control is regularly waved and the urine-wet alarm function, when the outside sound reached certain intensity, sound control circuit triggered drive part and generates an electromagnetic field, shaking table rises and shakes, and simultaneously loudspeaker are played music, electromagnet outage behind the setting-up time, shaking table stops, and loudspeaker stop to play music simultaneously.The wet probe of the external urine of warning circuit, when it detected urine-wetting signal, loudspeaker sent chimes of doom.

Because adopt above design, this shaking table can be done oscillating motion under the driving of electromagnetic field, have the function of acoustic control, timing and urine-wet alarm simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

In Fig. 1, (T1), (D1～D4) will supply with (T2) after the rectification of alternating current transformation, rectifier power source offers the circuit remainder after (W) voltage stabilizing, (MIC), (Q1), (Q2) etc. form sound signal amplifying circuit, (IC1) be subjected to it to trigger back output high potential and control DM through (K2), (Q5), (K2) break-make is controlled by itself and (L) relative position, (IC3) trigger end (e), (f) the wet detecting head of external urine, (R12), (C7) constitute delay circuit, setting (C9) can make the swing of shaking table more natural.Circuit arrangement shown in Figure 1 in insulation booth (J), (LED2), (LED1) indicate shaking table respectively shake, stop state.

In embodiment illustrated in fig. 2; rocking arm (a) and (b), (c), (d), parallel to each other and equal in length; the draw bail of they and rocker arm support (A), (B), (C), (D), (E), (F), (G), (H) is just the same, the centre position fixed installation control box (J) of base plate (R).

In Fig. 3, rocker arm support connects by axle (P) with rocking arm, and makes rocking arm reduce resistance to greatest extent when axle (P) is swung.

Among Fig. 5, it is cylindrical driving permanent magnet (M), and two end face is respectively the N utmost point, the S utmost point.Control permanent magnet (L) is little cuboid, and its two ends are respectively the N utmost point, the S utmost point.

Among Fig. 6, DM (T2) is to form around certain number of turn in the center pinch of " E " shape iron core with alignment enamel-covered wire directly, (M) be fixed on the center of bed board (I) bottom surface, its plane is between adjacent two iron core planes of (T2), the magnetic pole same polarity of (M) end face that the magnetic pole that the plane of requirement iron core center pinch produces is relative with it, adjust iron core end face and (M) distance between the end face, make to produce maximum thrust therebetween; Control magnetic pole (L) be fixed on the bed board bottom surface and (M) near, its status requirement (K2) is not subjected to the influence in electromagnet (T2) magnetic field that produces as far as possible when being installed in (L) below, adjust (K2) and make (K2) adhesive just with distance (L), (K2) can sensitive disconnection when arranging for bed board (I).
