Description

The shaking table of Electromagnetic Drive or rocking chair

Technical field

The utility model relates to a kind of swingable shaking table or rocking chair, especially relates to a kind of shaking table or rocking chair of Electromagnetic Drive.

Background technology

At present, common shaking table (comprising Children and adult's shaking table) or rocking chair etc. are sat bedding needs people to promote just can wave, and need be continuously applied external force, and swing just can be kept down.For this reason, people have designed a lot of electric cradles and rocking chair substitutes manually, these electric cradles and rocking chair mostly with motor as power, drive a body or the chair body shakes by certain transmission mechanism and oscillating control mechanism.Disclose a kind of automatic cradle bed as Chinese patent CN2585599, its cradle and motor link by transmission device, and by controller set shake rule and sequential is swung.

By to above technical Analysis, be not difficult to find that existing shaking table and rocking chair exist following deficiency: a. transmission mechanism and oscillating control mechanism complexity, be out of order easily,, just may cause product to use as long as one of them drive disk assembly breaks down; B. motor easily heating in the middle of long-time running and is accompanied by mechanical wear, thereby influences its life-span, and is serious even cause motor to burn out.C. motor, transmission mechanism are when work, and its noise and mechanical oscillation are bigger, and particularly baby's sleep influence is bigger to people.D. the price height because complex structure causes the production cost height, makes product be difficult to most of people because of price is too high and accepts.

Summary of the invention

The utility model purpose provides a kind of shaking table or rocking chair of Electromagnetic Drive, with solution prior art shaking table and the existing complex structure of rocking chair, and easy break-down, noise is big, price high-technology problem.

The utility model mainly solves above-mentioned technical problem by following technical proposals: it comprises bedstead or chair frame, control circuit, power supply, waves body, the described body that waves is provided with and waves fulcrum, describedly wave that body below is provided with electromagnet and near switch, at electromagnet and under near switch and certain distance with interval be respectively arranged with permanent magnet, described permanent magnet is fixed on bedstead or chair frame bottom.

As a kind of preferred version of the present utility model, described each side of body of waving is provided with two and waves fulcrum, and this end that waves fulcrum and connecting rod is hinged, and the other end of described connecting rod is hinged on the brace summer of bedstead or chair frame.

As another kind of preferred version of the present utility model, described each side of body of waving is provided with one and waves fulcrum, and this waves fulcrum and is hinged on the brace summer of bedstead or chair frame.

As another preferred version of the present utility model, described centre position of waving body below is provided with the counterweight box, describedly is arranged in the counterweight box near switch, electromagnet and power supply.

As another preferred version of the present utility model, described control circuit comprises near switch, load switch, describedly opens and closes by load switch control electromagnet near switch.Wherein near switch be tongue tube or Hall switch or optoelectronic switch or inductance near switch, load switch is triode or solid-state relay or electromagnetic relay.

As the further preferred version of the utility model, described waving can be placed cradle or mattress or chair cushion on the body.

In the utility model, waving body swings by the indirectly-acting in electromagnet magnetic field, wave the body position near switch by perception and control the work of electromagnet state, it is waving body be positioned at lowest order time energising acting, so this working method is more energy-conservation and help prolonging machine life.

The utility model adopts the Electromagnetic Drive structure, owing to do not have machine driving and contact, therefore has characteristics such as simple in structure, that cost is low, and dependable performance is stable.Silent during its work, overcome defectives such as traditional shaking table or rocking chair noise and vibration are bigger.In addition, be the swing naturally of waving body owing to waving, be not to control swing, so it wave to manually promotion is similar, very soft special hommization by the frequency of transmission mechanism and oscillating control mechanism setting.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

Fig. 1 is the schematic diagram of the utility model Electromagnetic Drive concrete structure;

Fig. 2 is the circuit equivalent figure of control circuit of the present utility model;

Fig. 3 is the perspective view that adopts a kind of shaking table of Electromagnetic Drive structure shown in Figure 1;

Fig. 4 is the perspective view that adopts a kind of rocking chair of Electromagnetic Drive structure shown in Figure 1;

Fig. 5 is the perspective view that adopts the another kind of shaking table of Electromagnetic Drive structure shown in Figure 1.

The specific embodiment

Electromagnetic Drive concrete structure of the present utility model shown in Figure 1 mainly by bedstead or chair frame 1, wave body 5 etc. and constitute, this waves body 5 and is provided with and waves fulcrum 3, wave body 5 below electromagnet 4 is installed and near switch 7, the 5-20mm place respectively is provided with a block permanent magnet 6 at electromagnet 4 and under near switch 7, and this permanent magnet 6 is fixed on bedstead or chair frame 1 bottom.By Fig. 2 further as can be known, this control circuit is by constituting near switch 8, load switch 9 etc., wherein near switch 8 be tongue tube or Hall switch or optoelectronic switch or inductance near switch, load switch 9 is triode or solid-state relay or electromagnetic relay.Because the electric current that electromagnet 4 operate as normal need is bigger, this opens and closes by load switch 9 control electromagnet 4 near switch 8.

Fig. 3, Fig. 4 are respectively the shaking table that designs by above-mentioned Electromagnetic Drive concrete structure and the perspective view of rocking chair.As shown in FIG., body 5 each side of waving of its shaking table or rocking chair are provided with two and wave fulcrum 3, wave at each and be hinged with a connecting rod 2 on the fulcrum 3, and the other end of connecting rod 2 is hinged on the brace summer 11 of bedstead or chair frame 1, tangles so that will wave body 5.On the support 10 of bedstead or chair frame bottom, be fixed with permanent magnet 6; corresponding with it; wave the configurable counterweight box 12 in centre position of body 5 belows; electromagnet 4 is installed in the counterweight box, near switch 8 and power supply (rechargeable battery) etc., be convenient to further protect the electrical equipment and the weight of optimizing structure like this.

Because waving body 5 is load bodies, therefore wave cradle or mattress or the chair cushion 13 that to place arbitrary shape on the body at this, all more convenient flexible when production, use like this, and saved the direct costs that need on its structure, strengthen as waving body such as cradles.

The utility model also can be designed to another kind of shaking table by Electromagnetic Drive concrete structure shown in Figure 1.See Fig. 5, described each side of body (can be the cradle through reinforcing) of waving only is provided with one and waves fulcrum 3, and this waves fulcrum 3 and can directly be hinged on the brace summer 11 of bedstead or chair frame.

Certainly; the utility model not only is confined to above-mentioned concrete structure; with electromagnet 4, exchange, wave fulcrum 3 and connecting rod 2 or the replacement of brace summer 11 on articulated manner as permanent magnet 6, also will fall in the protection domain of the present utility model near the position of switch 8.
