Abstract
The utility model relates to an electric cradle which is composed of a bed body, a bed frame used for supporting the bed body and a drive device. The drive device comprises an interlocking bar which is fixed to the bed body and provided with a soft iron, a coil curl and a controller which are fixed to the bed frame. The interlocking bar passes through the coil curl and makes use of the magnetic force effect generated between a magnetic field and the soft iron when the coil curl is powered on. The interlocking bar drives the bed body to rock on the bed frame and regulates the current size of the coil curl and the cycle of current supply, and thus the rocking range and cycle of the bed body can be controlled.
Description
The utility model relates to the shaking table of a kind of electric cradle, particularly a kind of Electromagnetic Drive.
Common shaking table, generally will choose ceaselessly promotes, and just can oscillate, and uses very inconvenient.For this reason, Chinese patent application has proposed a kind of electric cradle bed for No. 86207786, and it is shaken by the motor band worm screw and the realization of cranking arm, but this cradle complicated in mechanical structure, and need a motor.
The purpose of this utility model is the shaking table that a kind of Electromagnetic Drive will be provided, and it does not need motor, and is simple in structure, easy to adjust.
The electric cradle that the utility model relates to comprises the bedstead of a body, supporting bed body and the drive unit that is made of gangbar, coil and current controller, and the bed body links to each other with bedstead by bearing, and can shake around bearing.Be fixed with the gangbar that soft iron is housed on the bed body, gangbar is passed the coil that is fixed on the bedstead.When coil electricity, produce magnetic field in the coil, soft iron is subjected to the magnetic field force effect and is attracted on one side, makes gangbar drive the bed body and is flapped toward on one side.Because the effect of bed body weight power and above-mentioned magnetic force, periodically by electric current, the bed body will ceaselessly shake so in the coil.The size of regulating winding electrical current, the amplitude of shaking with regard to adjustable bed body.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.
Fig. 1 is the three-dimensional structure diagram according to the electric cradle that the utility model proposes.
Fig. 2 is the view of shaking of electric cradle.
Fig. 3 is the drive unit schematic diagram of electric cradle.
As shown in Figure 1, electric cradle is made of bedstead 1, bed body 2 and drive unit 3.The central upper portion point A place of bed body 2 links to each other by bearing 11 with bedstead 1, and can swing around bearing 11, and as shown in Figure 2, drive unit 3 comprises the gangbar 31 that is fixed on the body 2, is fixed on coil 32 and current controller 33 on the bedstead.Shaking by gangbar 31 of bed body 2 drives, gangbar 31 is passed coil 32, the magneticaction that produces when being subjected to soft iron fixed thereon 34 and swinging with coil 32 energisings, as shown in Figure 3, when controller 33 feeds electric current for coil 32, in coil, produce magnetic field, soft iron 34 is subjected to the effect in this magnetic field, just the motion of direction shown in the arrow in Fig. 3 makes gangbar 31 drive bed body 2 and is flapped toward on one side.If coil 32 outage, magnetic field force disappears so, because the gravity effect, to another side, therefore, the amplitude that can shake according to desired bed body 2 and cycle be set coil electricity size of current and supplying time at interval to backswing for bed body 2.In the present embodiment, current controller is to adopt the low frequency time relay.
Claims (1)
- A kind of electric cradle, constitute by bedstead 1, bed body 2 and drive unit 3, it is characterized in that drive unit 3 comprise the band soft iron 34 that is fixed on the body 2 gangbar 31, be fixed on coil 32 and current controller 33 on the bedstead 1, and gangbar 31 is passed coil 32.
