The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment one: as shown in Figure 1, the utility model magnetomotive automatic door comprises door leaf 1 and magnetic dynamic device, described magnetic dynamic device comprises the coil block 2 that is separately fixed at suitable promotion door leaf 1 opening and closing position again, as Fig. 3, this coil block 2 comprises coil 21 with hollow skeleton, is installed in slide core 22, back-moving spring 23 in the coil 21 and the power circuit 25 that is electrically connected with coil 21.Wherein, as shown in Figure 2, slide core 22 by unshakable in one's determination 221 and the material that can not be magnetized 222 be formed by fixedly connecting by screw thread, the material 222 that can not be magnetized can be made by materials such as wood, plastics, copper, aluminium, slide core 22 two are provided with limited cap, the sliding axle at its middle part is longer more than one times than the length of coil 21, limited cap exposes coil 21 outsides, its radial dimension is big than the internal diameter of coil 21, guarantee that slide core 22 is unlikely to skid off outside the coil 21, back-moving spring 23 is placed between 221 limited caps unshakable in one's determination and the coil 21 skeleton rearward end.Connect power circuit 25, the coil 21 inner magnetic fields that produce, built-in iron core 221 is moved along the centre bore direction of coil 21 skeletons by the electromagnetic force effect, and the end of the material 222 that drive can not be magnetized promotes door leaf 1 opens or closes it; (having deleted sentence in this) interrupting power circuit 25, electromagnetic force disappears, and back-moving spring 23 makes slide core 22 get back to the origin-location, prepares action next time.The big I of thrust that acts on door leaf 1 is regulated from the distance of door leaf 1 rotating shaft by the number of turn that changes coil 21, the voltage or the mobile fixed coil 21 at regulating winding 21 two ends, can just go to the position of standard-sized sheet or complete shut-down after making door leaf 1 stressed.
As shown in Figure 2, the limited cap end of the material that can not be magnetized 222 of described slide core 22 is embedded with a location magnet 223, after iron door leaf 1 (tree system door leaf can on door correspondence position increase iron block) is pushed to the precalculated position by the slide core 22 a coil 21 in, locate by the phase magnet 223 of another coil 21.The magnetic force of phase magnet 223 is suitable, and the unlikely slide core 22 that influences promotes the effect that door leaf 1 opens it or cuts out.
As shown in Figure 1, described coil block 2 is made up of the coil 21 of two same structures, one of them coil 21 is inlayed on the wall that is fixed on appropriate location, door leaf 1 back when being in fully open position (or on floor), and another coil 21 is inlayed to be fixed on the door eyebrow at door leaf 1 top.
Embodiment two: as shown in Figure 4, the utility model magnetomotive automatic door comprises door leaf 1 and magnetic dynamic device, described magnetic dynamic device comprises and is installed in the coil 21 and 22 that there is secured core a pair of centre that is fit to open door leaf 1 position, being installed in a pair of centre that is fit to close door leaf 1 position has the coil 23 and 24 of secured core, and the power circuit 25 that is electrically connected with coil 21,22,23,24.When door leaf 1 was in the complete shut-down position, coil 21 was approaching and corresponding with 22 positions, passed to reversing the current for respectively flygate coil 21 and 22, and coil 21 and 22 abutting ends produce like pole, and the homopolarity repulsive force acts on door leaf 1 front door leaf 1 is opened; When door leaf 1 was in fully open position, coil 23 was approaching and corresponding with 24 positions, passed to reversing the current for respectively the coil 23 and 24 of closing the door, and coil 23 and 24 abutting ends produce like pole, and the homopolarity repulsive force acts on door leaf 1 back side makes door leaf 1 close.Change the number of turn of coil, the size of voltage, but or change coil from the required thrust size of the distance by-pass cock door of rotating shaft, make door leaf 1 just go to the position of standard-sized sheet or complete shut-down.
A described clamshell doors coil 21 and 22 is inlayed respectively to be fixed on the eyebrow and top, door leaf 1 front, and another is fixed on respectively on the suitable position in door leaf 1 back and wall or floor the coil 23 and 24 of closing the door.
