The specific embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail; Should be appreciated that preferred embodiment is only for the utility model is described, rather than in order to limit protection domain of the present utility model.
The purpose of this utility model is achieved through the following technical solutions, a kind of automatic door, comprise doorframe 13 and door leaf 14, on described doorframe 13, be provided with the first permanent magnet 10, on described door leaf 14, be provided with power supply 1, switch 15 and coil 5, described power supply 1, switch 15 and coil 5 form a loop, and the position of described coil 5 is corresponding with the first permanent magnet 10, the magnetic field producing for cutting the first permanent magnet 10; On described door leaf 14, be also provided with infrared switch 2 and electromagnet, on described doorframe 13, be also provided with second permanent magnet 11 corresponding with electromagnet 3 positions; The output of power supply 1 is connected with one end of infrared switch 2, and one end that the other end of infrared switch 2 connects electromagnet connects, and the other end of this electromagnet 3 is connected with power supply 1; Described automatic door also comprises IR remote controller, for controlling the break-make of infrared switch 2.
In the present embodiment, on described door leaf 14, be also provided with regulating resistance 4, described regulating resistance 4 is connected between power supply 1 and electromagnet 3; The size of electric current in can regulating circuit.
In the present embodiment, described power supply 1 two ends are parallel with electric capacity 8; One end of described electric capacity 8 connects the positive pole of the first diode 9, and the negative pole of the first diode 9 is connected to one end of coil 5.
In the present embodiment, the other end of described electric capacity 8 is connected with the negative pole of the second diode 6 by electric-quantity display device 7, and the positive pole of the second diode 6 is connected to the other end of coil 5.
In the present embodiment, the part of removing the first permanent magnet 10 and the second permanent magnet 11 on described doorframe 13 is provided with silencer pad; Can further reduce sound at closing time.
In the present embodiment, described electric capacity and 6 of the second diodes are also in series with electric-quantity display device 7.
Operating principle of the present utility model is as follows:
When door is opened, power supply 1 produces a magnetic field to coil 5 energisings, when door is subject to very large power, will close suddenly, and magnet is repelled in the magnetic field that 1. coil 5 produces, and stops door to continue motion; 2. because door leaf 14 and the relative motion of doorframe 13 make the first permanent magnet 10, through the magnetic flux of coil 5, huge variation occur, coil produces induced-current in 5 loops, door leaf 14 is due to electromagnetic damping effect, be subject to moving and being obstructed after Ampere force, during this period of time, under the repulsion that door produces at coil 5 and the effect of Ampere force, close; When door is when touching switch 15, power supply 1 is not giving coil 5 energisings, and now door is slowly closed under the effect of Ampere force.When opening the door, only need press infrared remote controller, the direct current that power supply 1 produces specific direction makes electromagnet 3 magnetization, and identical with the second permanent magnet 11 polarity, and door is because repulsion effect is opened.Meanwhile, this design can also reach the object of " leaving a door unlocked ", if desired, uses this branch road of IR remote controller UNICOM, and this door can be in " leaving a door unlocked " state; Can reduce the number of times of repeat switch door, very practical in public places; When in " leaving a door unlocked " state needs at closing time, only need press IR remote controller, power supply 11 produces the direct current with above-mentioned opposite direction, this direct current makes electromagnet 3 magnetization, permanent magnet in certain distance on doorframe 13 is contrary with the electromagnet polarity on door leaf 14, and door is shut owing to being subject to attraction.In another closed-loop path, the induced-current producing in coil 5, after the first diode 9, the second diode 6 rectifications, is stored in electric weight on electric capacity 8, and after electric weight acquires a certain degree, electric capacity 8 can serve as power supply provides part electric energy, to reach energy-conservation object.
