Technical field
The utility model relates to a kind of deceleration device of door, specifically a kind of electromagnetic damping formula door deceleration device.
Background technology
The door deceleration device kind of Cun Zaiing is a lot of in the market, flexible closed type door deceleration device, automatic retractable door deceleration device, an automatic swing door deceleration device.These door deceleration devices all are pure machinery, underaction, and the inconvenience of opening the door also can make a noise.
Summary of the invention
The utility model is intended to address the above problem, and a kind of novel door deceleration device is provided, and it has overcome the pure machinery of traditional deceleration device, dumb, drawback that noise etc. is arranged, and its technical scheme that adopts is as follows:
A kind of electromagnetic damping formula door deceleration device, be included in the alternating current generator that door rotating shaft one side is installed, be provided with travelling gear between alternating current generator and the door rotating shaft, the output of alternating current generator is connected with a voltage amplifier circuit, the output of voltage amplifier circuit is connected with a voltage comparator, the voltage that arranges in the voltage that voltage comparator can be exported voltage amplifier circuit and the voltage comparator compares, the output of voltage comparator circuit is connected with the electromagnetic damping reducer, the electromagnetic damping reducer comprises a damping coil and is positioned at the electromagnet of damping coil below, be provided with metal rotary disk between damping coil and the electromagnet, metal rotary disk links to each other with the door rotating shaft, and the output of voltage comparator circuit is connected with the damping coil of electromagnetic damping reducer.
After adopting above-mentioned structure, because alternating current generator, voltage amplifier circuit, voltage comparator and electromagnetic damping reducer are set, generator can produce induced electromotive force signal and import in the voltage amplifier circuit, voltage amplifier circuit amplifies signal, and the voltage after will amplifying again is input in the voltage comparator voltage ratio set with device.Voltage after amplifying surpasses setting voltage, then conducting makes the conducting of electromagnetic damping reducer, the damping coil energising, damping coil will produce the line of magnetic induction that passes metal rotary disk, metal rotary disk is rotated, the line of magnetic induction and vortex interaction, produce a braking moment in metal rotary disk, the direction of rotation of braking moment and metal rotary disk, braking moment makes metal rotary disk slow down, thereby realizes the function that door slows down, and arranges thus to have overcome the pure machinery of traditional deceleration device, dumb, drawback that noise etc. is arranged, open the door conveniently noiselessness.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, electromagnetic damping formula door deceleration device of the present utility model is described in further detail.
As shown in the figure, electromagnetic damping formula door deceleration device of the present utility model comprises three parts, is respectively collection input, Signal Processing and braking deceleration three parts of signal.
Wherein, the collection importation of signal is included in the alternating current generator 2 that door rotating shaft 1 one sides are installed, be provided with travelling gear 3 between alternating current generator 2 and the door rotating shaft 1, when door rotates, utilize gear 3 transfer motion powers to give alternating current generator, the alternative electric generation chance produces induced electromotive force Ui, the output of alternating current generator 2 is connected with a voltage amplifier circuit 4, in the processing with this induced electromotive force signal input signal, induced electromotive force can change with the variation of rotor speed, when the door rotating speed is low, the induced electromotive force that produces is low, and when overexerting or high wind when scraping door, the rotating speed height of door, the induced electromotive force of generation are just high.
The signal input of the collection importation of process signal, obtain an induced electromotive force Ui, because the signal that obtains is very faint, so this signal is input in the voltage amplifier circuit, this signal is amplified, the output of voltage amplifier circuit 4 is connected with a voltage comparator 5, the voltage that arranges in the voltage that voltage comparator 5 can be exported voltage amplifier circuit 4 and the voltage comparator 5 compares, being input to the voltage U r that sets with device in the voltage comparator by the voltage U o after voltage amplifier circuit 4 amplifications compares, voltage after amplifying surpasses setting voltage, the circuit of conducting braking deceleration (T opens) then, otherwise the whether too fast judgement of rotating speed of door has been finished in not conducting thus.
The output of voltage comparator circuit 5 is connected with the electromagnetic damping reducer, signal through the Signal Processing part is judged, if the door rotating speed is too fast, the circuit of conducting braking deceleration then, the electromagnetic damping reducer comprises a damping coil 6 and is positioned at the electromagnet 7 of damping coil below, be provided with metal rotary disk 8 between damping coil 6 and the electromagnet 7, metal rotary disk 8 links to each other with door rotating shaft 1, and the output of voltage comparator circuit 5 is connected with the damping coil 6 of electromagnetic damping reducer; When the circuit turn-on of braking deceleration, the damping coil energising, damping coil will produce the line of magnetic induction that passes metal rotary disk, namely forms electromagnetic field between the magnetic pole of two electromagnet, and metal rotary disk is rotated, and cutting magnetic induction is answered line, produces eddy current at rotating disk; The line of magnetic induction and vortex interaction produce a braking moment in metal rotary disk, and the direction of rotation of braking moment and rotating disk is namely with the door direction of rotation; Braking moment makes metal rotary disk slow down, thereby realizes the function that door slows down; When the rotating speed of door was reduced to a certain degree, the voltage that alternating current generator produces was lower than setting voltage after amplifying, and the circuit of braking deceleration disconnects, i.e. damping coil no power, and eddy current disappears, and braking moment also disappears, thus door rotates naturally.
