Next, the object lesson of the circuit that is assembled with this control device 70 is described according to Fig. 7.
Illustrated circuit includes 80 and three relay R 1 of power supply (being dc source), R2, R3 in legend.The minus earth of power supply 80, on the other hand, at the solenoid 54 of the contact RS1 ' that is equipped with speed of a motor vehicle sense switch 81, relay R 1 with connecting between the positive pole of power supply 80 and the ground wire, above-mentioned locked component 30 and as the transistor 82 of switch means.Above-mentioned relay tip RS1 ' is equivalent to on-off switch of the present invention.
Speed of a motor vehicle sense switch 81 is arranged on the sliding door 10, and whether the travel speed that is used for detecting rolling stock more than certain speed, when this travel speed can disconnect when certain speed (for example 5km/h) is above, then can not connected when reaching this certain speed.
Transistor 82 according to the control signal of being exported from control device 70 with energising conducting or cut-out between solenoid 54 and the ground wire.Specifically, the connector of transistor 82 is connected on the solenoid 54, allows the emitter grounding, base stage then be to be connected to above-mentioned control device 70.
Above-mentioned open the door command switch 76 and simultaneously unlock switch 78 be arranged to above-mentioned speed of a motor vehicle sense switch 81, relay tip RS1 ', solenoid 54, and transistor 82 parallel with one another.Two switches 76,78 are constituted with tumbler switch, then can connect when conducting direction is operated, and the words of operating towards opposite cutting direction then can disconnect.And be provided with the coil RC2 of the relay R 2 of connecting, and in series be provided with the coil RC3 of relay R 3 with unlock switch 78 simultaneously with the command switch 76 that opens the door.
The coil RC1 of relay R 1 be arranged to this relay R 1 contact RS1 ', solenoid 54, and transistor 82 in parallel.And in series being provided with each relay R 2, contact RS2, the RS3 of R3, R1, RS1 with this relay coil RC1, these relay tips RS2, RS3, RS1 dispose parallel with one anotherly.
Relay tip RS1, RS1 ' have only connection when above-mentioned relay coil RC1 is energized, and same coil RC1 disconnects when non-energising.Similarly, relay tip RS2, RS3 have only as above-mentioned relay coil RC2, connect when RC3 is energized, and each coil RC2, RC3 disconnect respectively when non-energising.
These relay R 1, R2, R3 have when opening the door command switch 76 or make the function as driving mechanism for switches (back is described in detail) of relay tip RS1 ' connection when unlock switch 78 switches to conducting state simultaneously.
Next, merge the effect that comprises the circuit and the locked component 30 of this control device 70 with reference to the sequential chart explanation of Fig. 8 and Fig. 9.The sequential chart of Fig. 8 is to show 10 the actions when complete fastening position is opened of will pull, and the sequential chart of Fig. 9 is to show to make 10 the actions when being returned to complete fastening position of pulling.
At first, the state before vehicle arrives parking spot, under the state more than the certain speed, speed of a motor vehicle sense switch 81 is to disconnect as shown in Figure 7 in its travel speed, 54 feeder circuit is forced to cut off from power supply 80 to solenoid.
So, under this state, even shown in the left end of Fig. 8 mistake will open the door command switch 76 or simultaneously unlock switch 78 be operable to conducting state, can not supply power to solenoid 54 yet, locking is switched pin 56 under the tensile force effect of spiral winding spring 53 and be maintained at latched position.That is to say, can positively prevent to remove under steam the situation of door lock owing to the maloperation of each switch 76,78.
At this moment, lock-in detection switch 68 is switched into conducting state, and closing door switch 15 in order to allow sliding door 10 be in complete fastening position becomes conducting state.
Then, almost arrive parking spot and its travel speed when not reaching certain speed at vehicle, speed of a motor vehicle sense switch 81 is connected., in this stage,, relay tip RS1 ' can not power to solenoid 54 so also disconnecting.Except this speed of a motor vehicle sense switch 81 is connected, again by the command switch 76 that opens the door is operating as conducting state, the command signal of then opening the door can be input to control device 70 (moment T1 of Fig. 8), and relay tip RS1 ' connection under the effect of relay R 1, R2.
Specifically, allow relay coil RC2 energising by connecting the above-mentioned command switch 76 that opens the door, be accompanied by this energising relay tip RS2 and connect, and switch on the relay coil RC1 of this relay tip RS2 arranged in series, its result, above-mentioned relay tip RS1 ' connection.Relay tip RS1 also connects simultaneously, and then no matter relay tip RS2 is switched on or switched off, and relay R 1 all can remain on conducting state (self-sustaining).
On the other hand, control device 70 exports control signal to transistor 82 at the time point of the above-mentioned command signal of opening the door of input, and this transistor 82 is switched to conducting state.At this moment, because speed of a motor vehicle sense switch 81 and relay tip RS1 ' connect together, so can power from 80 pairs of solenoids 54 of power supply.That is to say that solenoid 54 can switch to conducting state.
By the electromagnetic actuation force of this solenoid 54, locking is switched pin 56 and is retreated into the latched position shown in the double dot dash line among Fig. 4 and the restriction of the arm 40 that unlocks.Be accompanied by lock-in detection switch 68 is switched to dissengaged positions.Control device 70 confirms that these switches 68 are to switch to dissengaged positions, confirms that just latch-release detects, and the gate drive signal that is used for opening sliding door 10 is outputed to the motor drive circuit 21 (T2 constantly) of driven for opening and closing device 20.
By the output of this gate drive signal, and 10 drivings towards opening direction of pulling begin.Specifically, driving pulley 23 is that the sliding door 10 that counterclockwise rotates about allowing in the figure slides towards the direction that is separated from each other as shown in Figure 1.At this moment, because revolving member 36 is to be fastened on the engaging pin 18 that is arranged on sliding door 10 1 sides, so revolving member 36 with the breakdown action interlock of sliding door 10 from Fig. 3 the stand up position shown in the solid line move to the obliquity shown in the double dot dash line among this figure, above-mentioned then engaging pin 18 breaks away from and only continues the breakdown action of sliding door 10 from revolving member 36.And along with the rotation of above-mentioned revolving member 36, lock arm 40 drops to than this mobile restriction site (double dot dash line position) below more from the horizontal level shown in the solid line of Fig. 3 (fastening position fully).
Above-mentioned gate drive signal is a pulse signal, and in order will sliding door 10 to be quickened gradually by this gate drive signal, the duty ratio of this signal is increased to maximum value (being 70%) gradually from 0% legend.And, arrive 70% time point at this duty ratio, that is to say that the time point (T3 constantly) that finishes in the acceleration of the opening direction of sliding door 10 switches to dissengaged positions with transistor 82.That is to say that the electric power that begins to interrupt solenoid 54 is supplied with, and solenoid 54 is temporarily switched to dissengaged positions.
Supply with by interrupting this electric power, the driving force of solenoid 54 disappears, though locking switching pin 56 is owing to the elastic force pressure of spiral winding spring 53 projects to latched position, because preexist has the lock arm 40 that moves to above-mentioned mobile restriction site, latched position can be do not arrived so pin 56 is switched in above-mentioned locking, the back side of lock arm 40 can be compressed by above-mentioned elastic force pressure.That is to say that switching pin 56 with respect to lock arm 40 lockings is along its direction of principal axis (start direction) butt.
Then, reduce the duty ratio (will open the door drive slow down) of above-mentioned gate drive signal gradually, this duty ratio is remained on the 20% buffering microrunning of opening the door.Then, the time point (T4 constantly) that arrives the position of opening fully at sliding door 10 switches to 4% with duty ratio, keeps the position of this complete opening.
Under the state of this complete opening, with command switch 76 rupturing operations of opening the door, relay R 2 is switched to dissengaged positions, and also can interrupt towards the input signal of control device 70.That is to say that the command signal of opening the door can interrupt just switching to the command signal of closing the door (moment T5 of Fig. 9).
Thereupon, control device 70 gate drive signal that will be used for closing sliding door 10 exports motor drive circuit 21 to.At this moment, the duty ratio of gate drive signal also can increase gradually, keeps this maximum value at the time point that arrives maximum value (being 70%) in legend.
Then, meeting reduce this duty ratio gradually and make to close the door to drive and slow down, arrive the approaching time point in the precalculated position of fastening position fully at sliding door 10, can begin to carry out this duty ratio maintained 20% the buffering microrunning of closing the door, and allow transistor 82 get back to conducting state simultaneously, and conducting is supplied with (T6 constantly) to the electric power of solenoid 54 again.Therefore, allow locking switch pin 56 and be pulled back to the non-locked position shown in the double dot dash line of the 4th figure from the latched position here.
When the sliding door 10 in left side during near fastening position fully, its engaging pin 18 can enter into the slot 36c of the revolving member 36 of the obliquity shown in the double dot dash line that is positioned at Fig. 3.And, the time point that is extend in this slot 36c by engaging pin 18 begins, along with move (among Fig. 3 be towards move right) of this engaging pin 18 towards closing direction, the direction (rotating counterclockwise direction among this figure) of revolving member 36 beginnings stand up position of solid line in this figure is rotated.The lock arm 40 that engages with this revolving member 36 overcomes the elastic force (elastic force pressure) of spiral winding spring 44 and begins clockwise direction rotation in this figure.At this moment, locking is switched pin 56 and is retreated into above-mentioned non-locked position, so can the action of above-mentioned lock arm 40 not impacted.
The driving of closing the door as mentioned above, close door switch 15 and be switched to conducting state, and, stop and 10 time points that stop of pulling at the position detection signal that detects the encoder that is built in motor 22, judge the position (temporary close position) that two sliding doors 10 have arrived mutual butt, with the duty ratio of gate drive signal from 20% rising to 30% and allow the driving force of closing the door promote (T7 constantly) before.Therefore, two sliding doors 10 are accompanied by the compressive strain of the elastomeric material 11 that is arranged on an end and are pressed together powerfully mutually, can arrive complete fastening position.
At this moment, in locked component 30, revolving member 36 arrives the stand up position completely shown in the solid line of Fig. 3, and the bearing surface 36g that automatically lock arm is positioned at its hook portion 36e fully closes correspondence position with roller 48 what the some P of this figure was connected to the engaging of lock arm 40.
Close fully in the correspondence position at this, fulcrum 38 is positioned on the extended line L of rolling tangential direction of revolving member 36 of above-mentioned abutment P, and lock arm 40 is positioned at so-called dead point.Even the elastic force of the elastomeric material 11 of above-mentioned sliding door 10 acts on the lock arm 40 from above-mentioned abutment P as reaction force (reaction force of the direction of opening the door) T, this reaction force T can not act on the power effect that lock arm 40 is rotated yet, and is to act on the lock arm 40 as compressive load specially.In other words, above-mentioned reaction force T is supported in fulcrum 38 1 sides with lock arm 40 when mediating.
Will pull 10 move to complete fastening position after, specifically the duty ratio of gate drive signal is dropped to 4% and the driving force of closing the door is reduced to be lower than the weak driving of usual driving force to keep use driving force, make the built-in timer of control device begin to move simultaneously.
The result that the driving force of will closing the door like this reduces, the reaction force T that is delivered to lock arm 40 from revolving member 36 can descend as shown in Figure 3, this lock arm 40 is kept and is closed correspondence position fully, switch pin 56 also at non-locked position in this time point locking, so be equipped with at for example above-mentioned complete close stance when foreign matter such as clothes clips between the sliding door 10, as long as the strength of opening direction is applied to words on the sliding door 10 with manual mode, can be subjected to power-assisted by the elastic force pressure of spiral winding spring 44 and can make revolving member 36 and lock arm 40 then can open sliding door 10 on one side, therefore just can allow above-mentioned foreign matter deviate from towards rotating with above-mentioned opposite direction.Closing when door switch 15 is switched to dissengaged positions, switch drive control device 20 is being judged as when carrying out the emergency opening operation, and the directions that sliding door 10 was opened towards the scheduled time drive.
On the other hand, close after driving force drops to F2 making, then do not carry out opening door operation, close door switch 15 in conducting state and the timer time in (in legend be the time point that reduces from driving force through 0.5 second time), the duty ratio of gate drive signal is risen to 30% again shift two sliding doors 10 onto complete fastening position again, simultaneously, transistor 82 is switched to dissengaged positions and solenoid 54 is cut off (T8 constantly).So by allowing the electromagnetic actuation force of solenoid 54 disappear, then locking switch pin 56 can be because the elastic force of spiral winding spring 53 and project to the latched position shown in the solid line of Fig. 4 and Fig. 5 from before non-locked position.By the existence that pin 56 is switched in this locking, lock arm 40 just can not depart from from the above-mentioned correspondence position of closing fully, and therefore, the sliding door 10 that is attached on this lock arm 40 via revolving member 36 is locked in above-mentioned complete fastening position.After detecting this lock out action, the duty ratio of gate drive signal adjusted to 0% (just cutting off the energising of motor 22) and finish to close driving by lock-in detection switch 68.
Then, when vehicle take-offs and its travel speed when certain speed is above, speed of a motor vehicle sense switch 81 disconnect and once more force disconnect from the power supply of 80 pairs of solenoids 54 of dc source.And simultaneously, the coil RC1 of relay R 1 also becomes non-energising, contact RS1, contact RS1 ' disconnection.
Though more than shown in action be the action of operation when opening the door command switch 76, and the basic lock out action when operating unlock switch 78 simultaneously can not change yet.
That is to say, when the travel speed of vehicle travelling more than certain speed, speed of a motor vehicle sense switch 81 disconnects, so even mistake simultaneously unlock switch 78 be operable to conducting state, can not allow solenoid 54 switch on yet, just can positively prevent the situation that unlocks under steam.Relatively, when the travel speed of vehicle does not reach the parking of certain speed or does not stop, speed of a motor vehicle sense switch 81 is switched on, and unlock switch 78 switches to conducting state simultaneously under this state, the coil RC3 energising of relay R 3, contact RS3 connects, the coil R1 of relay R 1 energising, and contact RS1, RS1 ' disconnection, and control signal is input to transistor 82 from control device 70, this transistor 82 switches to conducting state, and solenoid 54 is switched on and unlocked.
The command switch 76 and simultaneously in both states (just relay coil RC2, RC3 are in non-power status) of unlock switch 78 of opening the door is cut off in operation at the same time, even dropping to, travel speed do not reach certain speed and 81 connections of speed of a motor vehicle sense switch, can't be at this time point with solenoid 54 energisings (just unlocking).Contact RS2, RS3, RS1 disconnect in order not allow relay coil RC1 energising then allow relay tip RS1 ' disconnection.
In other words, under the state that speed of a motor vehicle sense switch 81 is connected, one of them of switch 76,78 begins to remove the power supply of prevention to solenoid 54 when being manipulated into conducting state.So, just can prevent positively that vehicle commander's etc. lock operation person from switching to solenoid 54 situation of conducting state (unlocking) between being not intended to.
The present invention is not limited to above embodiment, as an example, also can use ensuing mode.
In the above-described embodiment, as the instruction input switch, expression be to possess open the door command switch 76 and two switches of unlock switch 78 are simultaneously arranged, but also can be only wherein a side switch as instructing input switch.And under the situation of command switch 76 as the instruction input switch of will opening the door, after this switch 76 is switched to conducting state, to suitably set the sequential of carrying out latch-release or during preferable, for example also can in the switching process of door, often solenoid 54 be remained on conducting state.
In the above-described embodiment, though be to be speed of a motor vehicle testing agency and the locking maintaining body, the speed of a motor vehicle also can for example be set detect special-purpose sensor and come to force to stop control by control device 70 power supply of solenoid 54 according to this signal with speed of a motor vehicle sense switch 81 dual-purposes., speed of a motor vehicle sense switch 81 dual-purposes by will be as shown are speed of a motor vehicle testing agency and locking maintaining body, then just can stop latch-release in travelling with simple structure.
Even under the situation that with speed of a motor vehicle sense switch 81 dual-purposes is speed of a motor vehicle testing agency and locking maintaining body, its position is not limited to the position between illustrated power supply 80 and the solenoid 54, also speed of a motor vehicle sense switch 81 can be configured in position or the emitter-base bandgap grading of transistor 82 and the position between the ground wire between the base stage of for example control device 70 and transistor 82.
In the present invention, the concrete mechanism of tube winding apparatus is not how, for example can omit above-mentioned linkage part yet, allows the locking switching member directly be engaged on the holding section that is arranged on the car door and is locked, in addition, do not hinder the structure that is applicable to known locking mechanism.Also can directly the plunger that pin 56 is attached to solenoid 54 be switched in locking.
