Description

Drive unit

Technical field

The present invention relates to a kind of drive unit that is used for folding door, vertical hinged door or door.

Background technology

This drive unit generally comprises the driver that is made of motor, and this driver drives is used to open and close the operating element of the door wing of folding door.Operating element is made of a main shaft usually, and this main shaft is converted to the ejector sleeve (Schubrohr) that is connected on the door or the rectilinear motion of similar item with rotatablely moving of motor.For vertical hinged door and Men Eryan, corresponding device thereof is known.

Operate for the double spread door, control driver by control module.Usually, by control module be opening and closing predetermined one rate curve of determining respectively of folding door.This rate curve was made up of boost phase, interstage and deboost phase, in boost phase, make the speed of a wing accelerate to maximal rate, a wing is moved with maximal rate, and in the deboost phase, make a wing brake inactive state by maximal rate.

As the safety measure in the known drive unit of folding door, be provided with so-called power and cut off (Kraftabschaltung).When the power on acting on a wing surpassed a definite threshold value, power was cut off and is made the counter-rotating of folding door.

In this case, the motor current of split-phase motor, this motor current are the tolerance of load torque and are the tolerance of active force therefore.

Guarantee by this measure: when Men Yi bumped against obstruction, Men Yi no longer remained in operation, but was stopped running in the opposite direction then.

This power is cut off and should not only is used to protect the folding door to make it avoid damaging, but also is used for the purpose of personal protection.

In such known drive unit, regulate the threshold value of the starting of definition power cut-out by the potentiometer on the described control module.At this disadvantageously, each operating personnel must oneself regulate threshold value.Consequently do not produce danger in order to carry out described adjusting, operating personnel must know each fringe conditions and the parameter of folding door exactly, and promptly adjustment process is very complicated.At this especially disadvantageously, often by operating personnel's adjusting of operating physical force cut-out consciously.So it is so high that threshold value can be set up ground, and capable cut-out is not responded.Though this makes the folding door work incessantly.But desired security function lost efficacy.

An other difficulty is, adopts known power to cut off generally can only satisfy deficiently and is used for the safe precondition work of folding door, standard.

The effective safety standard regulation that is used for the folding door, when Men Yi collides obstruction, from the moment of the collision moment after collision, the power that acts on the obstruction should not surpass first limiting value, and in a time interval subsequently, power should not surpass second limiting value that is lower than first limiting value.

As long as the Men Yi of folding door has relatively little length, it is also unquestionable relatively to observe described standard limit value so.Under the situation of the long door wing, in the exterior zone of the door wing, the length of the handle (Hebel) by the door wing and because the big quality of the door wing, the power that acts on the obstruction in the short time the during collision of the door wing after the collision is so big, makes the limiting value that allows be exceeded.

Summary of the invention

Task of the present invention is, be provided for as far as possible little structure consumes the folding door drive unit, reliably and the operation of handling safety.

In order to solve this task, the feature of claim 1 has been proposed.Favourable form of implementation is the further configuration that meets purpose of the present invention, in the dependent claims these favourable forms of implementation is described.

Drive unit according to the present invention comprise driver and can be conditioned by this driver, for example be used to close and open operating element for the door wing of the door of folding door or vertical hinged door.Drive unit also has the control module that is used to control driver.Control module is disposed input block, by this input block can import as input parameter the door wing length.In control module, the important relevant parameter of other the manipulation for door is automatically derived by input parameter.In general, also can be used to door according to drive unit of the present invention.The ground that is without loss of generality below illustrates the present invention at the drive unit of control folding door.

Significant advantage of the present invention is, just can realize the duty adjusting of described drive unit by importing a unique input parameter, and this duty is regulated and made the reliably working for different doors become possibility.At this, the present invention is based on following understanding, promptly can by derive as the door chord degree of input parameter all other, for the important relevant parameter of the reliably working of folding door.

The door chord degree of folding door is the folding door parameter that can determine very simply, and unskilled personnel also can implement the predetermined of this parameter like a cork.Therefore, the parametrization of the drive unit of different doors can be implemented simply and fastly.

Particularly advantageously, by predetermined door chord degree, can satisfy security regulations work, standard that are used for the folding door as unique input parameter.

In a particularly advantageous form of implementation of the present invention, the speed parameter of the rate curve when for this reason deriving definition opening and closing folding door by described input parameter.Described speed parameter advantageously is made of the maximal rate and the moment of starting deboost phase of the motion of the door wing, and the Men Yicong maximal rate is braked to inactive state in this deboost phase.

At this, carry out the predetermined of speed parameter like this, make maximal rate be inversely proportional to selected door chord degree.In addition, door chord degree is big more, and the moment of deboost phase is by selectively more early.

Selection by this speed parameter, the speed of the door wing not only make this wing with the stage of constant maximal rate motion in and also in time before this boost phase and all be complementary in after this deboost phase on the time with the length of the door wing, thereby make the standard limit value that when Men Yi bumps against on the obstruction, is used in the permission of the power of this appearance can not be exceeded.

This is based on following situation, and promptly the power of Chu Xianing is proportional to the kinetic energy of a wing, and this kinetic energy is with square increase of speed.By the beginning that reduces according to the present invention to be inversely proportional to the maximal rate of a length and correspondingly to change the deboost phase, realized not relying on basically under the situation of a wing in qualitative difference, the power that occurs when Men Yi collides obstruction is no more than the limiting value of permission.

At this, the notion of maximal rate refers to the parameter that is directly proportional with the rotating speed of driver.Because this parameter changes inversely with door length, so obtain the peripheral speed of the folding door of substantial constant for different door length.

In a particularly advantageous form of implementation of the present invention, also derive the threshold value that is used for the power cut-out by the input parameter of door chord degree.At this, the size of this threshold value is selected as being proportional to a chord degree.This means, under the situation of bigger power value, also use power to cut off with bigger door length.

This based on: select a speed parameter to guarantee that the power that occurs is no more than the limiting value of standard on the Shi Zaimen that bumps by depending on length ground, thereby especially for personnel, danger can not occur.Therefore, the threshold value that power is cut off can with the size of the door wing, especially the length with the door wing is complementary.This coupling is carried out as follows, i.e. the sensitivity of power cut-out is independent of a length ground and keeps constant.The tolerance of this sensitivity is the torque that acts on the driver.

On the one hand by the reverse dependence of maximal rate and door chord degree and on the other hand by the threshold value of power cut-out and the dependence of door chord degree, the same parametrization of having guaranteed the handling safety of described drive unit in simple mode.

If operating personnel attempt to carry out following operation: the value of importing a low excessively door length, so that realize the quick opening and closing of door, because improved corresponding maximal rate thus, thus the predetermined corresponding lower value that is used for the threshold value that power cuts off in control module thus.This causes the availability of drive unit significantly to descend, because power is breaking under the situation of little interference, has for example just made motion that response makes door then during storm wind and has stopped and reversing.

The specific embodiment

Fig. 1 schematically shows the drive unit 1 that is used for the folding door.This folding door has a wing 2, and it is rotatable that this Men Yi is placed as the axle 3 that (perpendicular to the plan among Fig. 1) extends about in vertical direction.

Drive unit 1 comprises the driver 4 that is configured to motor, and this driver is by control module 5 controls.Motor is constructed to dc motor.Control module 5 can be made of microprocessor or similar item.Control module 5 can be integrated in the driver 4 as shown in the figure or be constructed to independently unit.

In present case, drive unit 1 is used as spindle driver, and this spindle driver has the main shaft 6 as operating element.By main shaft 6, rotatablely moving of driver 4 is converted into the rectilinear motion of ejector sleeve 7.Ejector sleeve 7 is connected on the wing 2.By the rectilinear motion of ejector sleeve 7, make a wing 2 around the axle rotation, to open and close the folding door.The direction of rotation that is used for opening and closing door is represented with " pass " and " opening " at Fig. 1.Other input block that also can have different user interface form.In addition advantageously, be provided with the display element of the value that is conditioned that is used for visual door length.

On control module 5, be provided with and be used for drive unit 1 is carried out parameterized input block.This input block can be made of or one or more button constitutes potentiometer.

When opening and closing the folding door, make a wing 2 respectively according to predetermined rate curve motion.Fig. 3 exemplarily shows the exemplary velocity profile of the door wing 2 in opening procedure.In the time interval is that t=0 is to t=t ₁Between boost phase in, the door wing 2 speed v from v=v ₀Rise to maximal rate v=v linearly _Max(area I).At t=t subsequently ₁With t=t ₂Between area I I in, the door wing 2 with constant speed v=v _MaxRunning.At t=t subsequently ₂With t=t ₃Between deboost phase in, the door wing 2 be braked to inactive state, thus the door wing 2 enter its open position.In present case, speed descends at the deboost phase neutral line.Alternately, speed descends at the deboost phase neutral line, up to reaching a minimum speed, thereby makes a wing 2 enter its open position with this minimum speed subsequently.

In general, the rate curve that is used for closing door has a wing 2 at the corresponding speed time changing curve of Fig. 3.Maximal rate when usually, closing is selected as the maximal rate when opening.

The pulse width modulation of the predetermined motor voltage by motor of the speed of the door wing 2 is carried out.Figure 2 illustrates the corresponding time diagram of this voltage.At this, as can see from Figure 2, motor has been applied in the potential pulse of variable-length.Select the pulse sequence frequency of potential pulse like this, make motor only write down the time average of the voltage after the modulation.This depends on pulse width modulation.

By changing pulse width modulation, at first reduced the rotating speed of driver 4.Obtained the change of the peripheral speed of the door wing 2 thus.

For drive unit 1 is carried out parametrization, by the length of input block input as the door wing 2 of unique input parameter.Then, calculate other parameter of required all of the work of drive unit 1 by this input parameter.For this reason, store indicatrix in control module 5, in these indicatrixes, the analog value of each parameter is assigned to the different value of the length of a wing 2.Alternately, can stored algorithm, carry out distribution between input parameter and the parameter by these algorithms.

Especially speed parameter belongs to the parameter that is derived by input parameter, and these speed parameters have defined the rate curve that is used to close closed procedure and opening procedure.In present case, in control module 5, calculate independent speed parameter respectively for closing closed procedure and opening procedure.

First speed parameter is a maximal rate.This maximal rate changes inversely with the length of the door wing 2.The second speed parameter is the beginning of deboost phase, i.e. moment t among Fig. 2 ₂The length of gate flap is big more, and more also there is the linear relationship of these two characteristic values in the beginning of deboost phase by selectively.Maximal rate is the parameter that is directly proportional with the rotating speed of driver 4.By this parameter inverse relation long, obtain the peripheral speed that is independent of a length basically of a wing 2 with door.

Fig. 3 schematically shows reformed rate curve by the parameter variation.At this, figure 3 illustrates the rate curve of three different lengths that are used for a wing 2.The rate curve of representing with a is corresponding to the rate curve according to Fig. 2, and this rate curve is the determined value L for the length of the door wing 2 ₀Predetermined obtain.A value L=L who is reduced of the length by the predetermined door wing 2 ₀-Δ L obtains the rate curve of representing with b among Fig. 4.According to the inverse relation of the length of the door wing 2, the value of maximal rate is from v _MaxDrop to v _{Max '}And the value of the beginning of deboost phase is from t ₂Be reduced to t _{2 '}A value L=L who is further reduced of the length by the predetermined door wing 2 ₀-2 Δ L obtain the rate curve of representing with c among Fig. 4.In this rate curve, also obtain the maximum speed value v that is further reduced _{Max "}Initial value t with the deboost phase _{2 "}

As other parameter, by input parameter, promptly calculate threshold value by the length gauge of the door wing 2, this threshold value has defined the on-condition of the power cut-out that is used for the folding door.By suitable, be integrated in the motor or be integrated in sensing mechanism in the control module 5, calculate as the tolerance of the load that produces on the motor and therefore as the motor current of the tolerance of active force.With threshold value this power is analyzed.In case this power surpasses threshold value, just carries out the counter-rotating of driver 4.

This threshold value is selected as being proportional to the length of a wing 2 in present case.Therewith correspondingly, power is breaking under the situation of the longer door wing and only just can works under the situation of bigger power.

By calculating the parameter of drive unit 1 according to the length of the door wing 2, can satisfy safety requirements operation, standard that is used for the folding door.

In time diagram, this is illustrated according to Fig. 5.Fig. 5 show the power that acts on the test object the limiting value that must observe, these power produce when a door wing 2 collides test object.At this, among the figure in Fig. 5, the door wing 2 that moves with a speed bumps with the test object of standing at moment t=0.Safety standard requires at t=0 and t=t _aBetween the time interval in, promptly and then after the collision power that appears on the test object be no more than limiting value S ₀At t=t subsequently _aWith t=t _bBetween the time interval in, the power that acts on the test object should the value of overstepping the extreme limit S ₁

These require also must especially be met when test object is run in the outer end of the door wing 2, promptly are met in the place that power occurred of maximum.

By the variation of parameter, especially the variation according to the speed parameter of Fig. 4 makes rate curve and each length of the door wing 2 be complementary.At this in general, the length of the door wing 2 is big more, and the speed of the door wing 2 is fallen lowly more.Realized that thus when the door wing 2 and test object bumped, the power that acts on this test object remained on as shown in Figure 5 by limiting value S ₀And S ₁In the predetermined limit.
