Abstract
The utility model relates to an electromagnetic driver of the rocking chair, mainly comprising a permanent magnet, a U-shaped electromagnet, a direction detector and an electromagnetic controlling circuit. The electromagnetic driver of the rocking chair can automatically identify the reciprocating movement direction of the rocking chair by the direction detector, and the electromagnetic controlling circuit has the U-shaped electromagnet generated magnetic field which drives the reciprocating movement of the rocking chair stand provided with the permanent magnet. The utility model has simple structure, big driving force, stability, and no noise, and can be used as the driver of the rocking chairs, concentrating tables, etc.
Description
One, technical field:
The utility model relates to a kind of rocking chair electromagnetic driver that is produced the swing of magnetic field promotion rocking chair by hot-wire coil.
Two, background technology:
Commercially available rocking chair is the simplest for manually self to shake at present, no drive unit.Complicated a little any electric rocking chair arranged, be that mechanism such as buncher is set below rocking chair.This mechanism structure complexity, noise is big.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, rocking chair electromagnetic driver that noise is little.
The technical solution of the utility model is: mainly be made of permanent magnet, U type electromagnet, direction detector, Electromagnetic Control circuit board, it is characterized in that: permanent magnet is arranged on the rocking chair mounting transverse link, and its N utmost point down; U type electromagnet be arranged on permanent magnet under; Direction detector is arranged on the below of rocking chair mounting transverse link; The Electromagnetic Control circuit board is arranged on the pony sill of rocking chair; Two groups of series of coils of described U type electromagnet are connected with the two control of the controllable silicon full-bridge circuit of Electromagnetic Control circuit board by two leads; Two groups of coils of described direction detector are connected with the oscillating circuit of Electromagnetic Control circuit board by three leads.
Direction detector of the present utility model is made of FERRITE CORE and two groups of coils.
Electromagnetic Control circuit board of the present utility model is made up of oscillating circuit, rectification shaping circuit, controllable silicon Drive and Control Circuit, the two control of controllable silicon full-bridge circuit.
The controllable silicon Drive and Control Circuit of Electromagnetic Control circuit board of the present utility model is with NE555 integrated package and triode BG
4The driving of making the two control of controllable silicon full-bridge circuit triggers.
The utility model is owing to be arranged on permanent magnet on the horizontal connecting rod of rocking chair mounting below, its U type electromagnet is arranged on the below of permanent magnet, when the magnetic pole of U type electromagnet changes, can drive the transverse link generation that is provided with permanent magnet and move back and forth, thereby drive rocking chair mounting front and back reciprocally swinging.And, thereby do not have other transmission mechanism during the Electromagnetic Drive mounting, so there are machinery vibration, also noiseless during the rocking chair motion because the mounting of rocking chair is to be suspended on the pony sill by four suspension rods that tape spool holds.
Four, description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is an electrical schematic diagram.
Among the figure: 1, permanent magnet; 2, direction detector; 3, U type electromagnet; 4, Electromagnetic Control circuit board; 5, rocking chair mounting transverse link.
Five, embodiment:
As shown in Figure 1, the utility model is made up of permanent magnet 1, direction detector 2, U type electromagnet 3, Electromagnetic Control circuit board 4, and permanent magnet 1 is fixedly installed on the rocking chair mounting transverse link 5, can move back and forth with transverse link, and the N of its permanent magnet is extremely downward.Direction detector 2 is arranged on the below of rocking chair transverse link, U type electromagnet 3 be fixed on permanent magnet 1 under the rocking chair pony sill on.Direction detector is by FERRITE CORE and two groups of coil L
1L
2Form, described two groups of coils connect with the oscillating circuit of Electromagnetic Control circuit board by three leads; Two groups of series coil L of U type electromagnet
3L
4Connect with the two control of the controllable silicon full-bridge circuit of Electromagnetic Control circuit board by two leads.When the rocking chair mounting moved, direction detector detected direction immediately under the control of circuit, was controlled the break-make of solenoid again by detector.When the rocking chair mounting when travelling forward, detector detects and exports the signal that travels forward immediately, produces the S magnetic pole behind the previous coil electricity of electromagnet, a back coil produces the N magnetic pole.Because the same sex in magnetic field is repelled each other, principle of opposite sex attraction,, the permanent magnet that is suspended from U type electromagnet top is pushed away forward by U type magnetic field that electromagnet produces.Magnetic field that coil produced, back pushes away forward, and inhale forward in the magnetic field that previous coil produced; When rocking chair when moving backward, detector detects and exports motor message backward immediately, producing magnetic field behind the previous coil electricity of electromagnet is the N utmost point, the magnetic field that the coil in back produces is the S utmost point, the magnet of U type electromagnet top is motion backward again, the magnetic field that is previous coil generation is to pusher, and inhale backward in the magnetic field that back one coil produces.Like this, the permanent magnet that is suspended from U type magnet top moves again and again, just drives the rocking chair mounting and seesaws.
Because the mounting of rocking chair is connected with four suspension rods that pony sill has only tape spool to hold, during the field drives mounting, be as medium with air, promptly do not have connecting rod, do not have reducing gear again and link to each other, so rocking chair does not have the machinery vibration when moving, noiseless, and produce electromagnetic driver processing simply, with low cost, easy for installation.
As shown in Figure 2, Electromagnetic Control circuit board of the present utility model is made up of oscillating circuit, rectification shaping circuit, controllable silicon Drive and Control Circuit, the two control of controllable silicon full-bridge circuit, and the controllable silicon Drive and Control Circuit is by NE555 integrated package and triode BG
