Technical field

The utility model relates to a kind of rocking equipment, and it relates generally to a kind of for example being installed in: baby child uses the magnetic force rocking equipment in swing, rocking chair or the shaking table.

Background technology

Baby child does not in the past have power in early days with swing, rocking chair or shaking table, and the head of a family needs to promote with the hand-held continuous application of force, just can make its lasting oscillating motion.Then have the designer to develop the electrodynamic type swing function, it is by setting up electro-motor to reach the purpose that promotion is waved.This kind electro-motor, owing to be to adopt mechanical drive, noise is big during use, and its cost height, complex circuit designs adds that consumption of current is big, and is unsatisfactory.

Based on above-mentioned defective, if can design the rocking equipment of a kind of low power consumption, low cost, low noise, and be applied in child's swing, rocking chair or the shaking table, must improve the long-standing shortcoming of making us dirty disease of existing product.

Summary of the invention

The purpose of this utility model is, a kind of saving energy is provided, simultaneously simple structure, rocking equipment with low cost.

Main technical schemes of the present utility model is that this power conservation type magnetic force rocking equipment includes: fixed body with wave body, be provided with cooresponding pivot connecting element and swing unit therebetween.Wave body and can pass through cooresponding pivot connecting element and swing unit, enable to carry out reciprocal oscillating motion with respect to fixed body.

Aforementioned fixation body and waving between the body is provided with rocking equipment, wherein includes induction coil and magnetics.Induction coil and magnetics are proximity relations, and magnetics can be corresponding to the displacement of induction coil reciprocally swinging.For making induction coil and magnetics have the effect that magnetic force waves, the collocation induction coil has designed control circuit.

When waving body when waving with respect to fixed body, induction coil and magnetics do not have the induction effect of magnetic force displacement, and each assembly all is quiescence, and the consumption of electric power is not arranged this moment; When waving body when waving with respect to fixed body, induction coil and magnetics can carry out magnetic force induction, the induction coil intermittent use, and sustainable reciprocal promotion is waved body and is waved.

Power conservation type magnetic force rocking equipment of the present utility model adopts the contactless rocking equipment of magnetic force induction, and it utilizes permanent magnet and induction coil relative motion, can produce induction by current and magnetic force mutual repulsion effect, and then obtains the purpose of swinging driving; Its takeoff output and rocking motion are synchronous fully, can be strong afoul situation take place, move smoothly the advantage quiet especially noiselessness except that having; Wherein induction coil only is provided with one, utilizes same induction coil, can make circuit reduction with inducing current and load function such as exert oneself, and cost reduces, to promote product competitiveness; Simultaneously, whether its rocking motion operates the induction of looking closely coil and controls, so swinging condition can quit work when stopped by foreign compulsion automatically; Otherwise, when swinging condition is started by external force, can resume work automatically; Its automation inducing function, safety not only in the use has more the advantage of power saving.

In sum, the utility model power conservation type magnetic force rocking equipment utilizes magnetic force to respond to and wave, noiselessness, and low power consumption, safe and practical.

The specific embodiment

Below with regard to the particular content of the utility model power conservation type magnetic force rocking equipment and the effect that can produce, in conjunction with the accompanying drawings with preferable

Embodiment is described in detail as follows:

At first see also Fig. 1 and shown in Figure 2, the utility model power conservation type magnetic force rocking equipment includes: fixed body 1 with wave body 2, be provided with cooresponding pivot connecting element 3 and swing unit 4 therebetween.Waving body 2 can enable to carry out reciprocal oscillating motion with respect to fixed body 1 by cooresponding pivot connecting element 3 and swing unit 4.

Aforementioned fixation body 1 and waving between the body 2 is provided with rocking equipment 5, wherein includes induction coil 51 and magnetics 52.Induction coil 51 can be fixed at fixed body 1 one sides, the side plate 11 of fixed body 1 one sides, offer short slot 12, this short slot 12 can provide the magnetics 52 of being located at swing unit 4 one side appropriate locations to lean out, make induction coil 51 and magnetics 52 are proximity relations, and magnetics 52 can be corresponding to induction coil 51 reciprocally swinging displacements.

For making induction coil 51 and magnetics 52 have the effect that magnetic force waves, see also Fig. 3, be the designed control circuit of collocation induction coil 51 in the utility model, mainly include induction coil L, one end is connected to direct supply, another corresponding end except that being connected with capacitor C 1, C2, resistance R 1, R2 and op amp (OP AMP IC), also is provided with transistor Q1.

When the state of kinematic motion of induction coil L induced magnetism element 52, magnetics 52 near the time, induction coil L produces the inducing current of positive phase; Otherwise when magnetics 52 left, induction coil L produced the inducing current of minus phase.This inducing current is stored by C1, and amplifies via op amp (OP AMP IC); The stored electric current of C1 slowly docks via R1 and is located in discharge, constitutes the function of time-delay; As for by op amp (OP AMP IC) institute's amplified current, via transistor Q1 to make induction coil L conducting electric current; The induction coil L of this conducting electric current can produce the magnetic field with magnetics 52 identical polars, and produces the strength of mutual repulsion with magnetics 52, and then is able to magnetics 52 is pushed open; Behind the C1 stored current discharge off, op amp (OP AMP IC) and transistor Q1 are the OFF state of " 0 ", can make induction coil L cutoff current; In this way, back and forth wave by continuing, can make induction coil L intermittent use, to reach the effect that magnetic force waves.

As from the foregoing, when waving body 2 when waving with respect to fixed body 1, promptly as the position of Fig. 1, induction coil 51 and magnetics 52 do not have the induction effect of magnetic force displacement, and each assembly all is quiescence, and the consumption of electric power is not arranged this moment.

When waving body 2 when waving with respect to fixed body 1, for example the head of a family is with hand propelled, and promptly as the position of Fig. 2, induction coil 51 can carry out magnetic force induction with magnetics 52, induction coil L intermittent use, and sustainable reciprocal promotion is waved body 2 and is waved.

Present embodiment has more following characteristics:

One, since time of the each conducting of transistor Q1 only about about 0.5 second, all the other not power consumptions of time, quite power saving.

Two, utilize the discharging function of electric capacity time-delay, can make the current lead-through time expand of induction coil L, and tool is economized electrical efficiency.

Three, by the op amp (OP AMP IC) of low-power consumption, low voltage, the Weak current of induction coil L can be amplified, and can under low voltage, work (more than about 2.2V), the employed dc-battery power source life of electronic circuit is able to for a long time.

Four, wave body and fixed body side because induction coil and magnetics are located at, therefore distance therebetween can not be subjected to waving the child's body weight influence on the body, and the advantage that need not adjust is arranged.

The experiment proved that, with four of alkaline C-size batteries, under the condition that load is ten kilograms, the variation of apparent rolling speed control, about 116～65 hours of sustainable use, the excellent effect of its power saving can meet consumer demand really.

The enforcing location of aforementioned induction coil 51 and magnetics 52 can be exchanged as required.
