Be described in more detail this electric control system below with reference to Fig. 5-8.According to the present invention, the mechanical position sensor that adopts micro switch is provided, this micro switch corresponding to the reciprocating motion by the object that motor drove, is exchanging the polarity of motor power in the situation of door bolt bolt 11.The power supply of this mechanical type response can also combine with Electronic Control to work and start opening of door by relay switch, and this will describe referring to Fig. 8 below.
As shown in Figure 5, cam member 101 is arranged to fasten bolt 11 with a bolt or latch identical around same axle 15 rotations, and is subjected to being coupled to the driving of projection 140 of the groove 141 of door bolt bolt 11.Also show clearly among Fig. 5, the breech lock casing has three parallel layers, does the rigidity interconnection by the hinge on the axle 15 that is common to cam member 101 and door bolt bolt 11 for these three layers.Cam member 101 can slide up and down on its rotation, so that the driven micro switch actuator 111,121 of cam and 131 can be followed rectangular cam track C, B, A shown in Figure 6 respectively.Cam member 101 is subjected to the loading of disc spring 19, is moving downward shown in arrow 191 among Fig. 6 moving upward among Fig. 5.The group of three micro switch 110,120,130 is connected on the breech lock casing 100 rigidly, and corresponding micro switch actuator can be laid along they rectangular cam tracks separately.
The surface towards the micro switch group of cam member 101 is shown among Fig. 6 with the size of amplifying.The unblanketed part of each cam rail is the darkest, and is represented as the line among Fig. 5 102; Dark shading district among Fig. 6 represents the ground that cam rail is shallow, shown in the line among Fig. 5 103.From the slope of distinguishing more shallow district more deeply then by the shadow representation of intermediate concentration Fig. 6.Each rectangular cam track by shown in rectangular wall and determined by median wall 104,105 and 106.The micro switch actuator 111,121 and 131 of aciculiform represented by the circle among Fig. 6, is in to show that their are along on position that cam rail moves separately.When door is opened, the micro switch actuator promptly is in the upper right corner of cam rail shown in Figure 6; When door begins closure, their relative position just moves to position shown in A among Fig. 6, B, the C according to direction shown in the alphabetical L.At such some place, door is opened fully.
When door bolt bolt 11 when shifting to the position of opening the door, along oblique by middle cam rail B and with the consecutive structure H of the end face of midfeather 105, make whole cam pack 101 move upward along being carried among Fig. 6 of spring of direction M resistance.This is because due to the sliding cam motion of pin 121 on structure H.Along the continuing to move and make the micro switch actuator turn back to position F of direction K, in this position, spring force 191 brings back to the upper right corner to them, and as shown in Figure 6, this moment, cam pack moved according to direction N.Slope E impels that cam actuator is recessed to enter in each micro switch, makes micro switch change to " leading to " from " breaking ".Steep structure H allows micro-actuator to eject once more, and micro switch is disconnected.
Below with reference to the control of Fig. 7 and 8 explanation motors, these two charts are understood the another kind of arrangement form of Circuits System.In automobile, each is motor 70 control by himself, and each has red emergency warning lamp alerting driver and passenger this is being opened simultaneously.Automobile has the central electronic control circuit 90 of common type and the stall current sensor circuit system 91 of integration.The switch of first micro switch, 110 control gate emergency warning lamps 80.Second micro switch 120 provides a kind of electric power of polarity to adapt with the closing control with door to motor.The 3rd micro switch 130 adapts with the control of opening with door to the motor power supply by opposite polarity.Fig. 5 and 6 mechanical arrangement have guaranteed that these switches work in the correct order.Adopt conventional mark, NO represents often to close terminal, and NC represents normally closed terminal and C represents common terminal.When door was closed, the micro switch actuator was in position A, B and the C among Fig. 6, and all micro switch disconnect.Motion towards open position impels the micro switch actuator to show to motion according to the arrow K among Fig. 6, and when passing through a spot of intermediary movements, when actuator 131 was positioned on the E of slope, micro switch 130 was just connected.This makes the auxiliary door of electric power open.When door was opened, door stand by lamp control micro switch was just connected when actuator 111 is positioned on himself slope.When door reached the auxiliomotor terminal point of its electric power, the micro switch 130 of opening the door disconnected, and has only an emergency warning lamp to continue to connect.When door is closed once more, close the gate control micro switch and be positioned at its just demand working on the slope of Fig. 6 center line F the time, and the door emergency warning lamp disconnects at actuator 121.
When door is closed fully, when actuator 121 is fallen on the step at the line G place among Fig. 6, close 120 disconnections of gate control micro switch.
The unlatching of door is preferably in 90 times startings of central electronic control circuit, can realize this starting by the relay switch among Fig. 8 140.Signal from central electronic control circuit 90 is powered to motor along circuit 150 engage relaies 140, and keeps time enough to make mechanical device move to 130 connections place of the 3rd micro switch.This relay switch disconnects or break-off then.
Stall current sensor circuit system 91 need not described in detail.In this example, it provides the line breaker of overcurrent protection, and can be by manually resetting when opening circuit.The current sense of CD-ROM drive motor electric current occurs on its earth-return, and current sense is to be that the resistor that suitable integrated differential amplifier amplifies is realized by its voltage.Second amplifier determining resistance value and the reference voltage level that provides by the temperature stabilization diode between voltage difference.This second differentiating amplifier plays the effect of comparator, the logic level conversion is provided and exports stall signal.
Be provided with telecontrol transmitter in the usual way and control central locking system, for example can untie or lock automobile from the outside.Can open car door or special door with identical instruction by remote control by central control system.But can operate electronic child safety lock by similar remote control thereof according to a present invention.
The central electronic control circuit system preferably receives the input from these sensors, and some in them is located within the breech lock can determine described pawl, door bolt bolt and pawl actuator or any other position component of bolt lock mechanism.Some other sensor then preferably is arranged in the state that automobile engine is for example gone to monitor in automobile other place.For example started and automobile when having started when motor, can be by the electric current of central electronic control circuit system sever supply CD-ROM drive motor.So just protected the accident of unexpectedly door being opened safely by electric power.As another example, if door is by jam and motor when driving stall, current sensor circuit system 91 just sends an information and gives electronic control circuit system 90, cut off to give this motor power supply, until detecting some advantageous conditions when for example by manually making the door handle pine oil door having been moved to certain position.
Above-mentioned special arrangement mode can reduce cost in the automobile scope significantly.This just can make length of arrangement wire minimize in the breech lock casing by switch is located at, in fact, essential wiring can be reduced to four lines 150,151 and 152 shown in have only shown in Fig. 7 two lead-in wires or Fig. 8, latch is connected with the central control circuit system.By making an emergency warning lamp and latch integrated, for example adopt simple plug-in type lamp, just can make wiring and assembly expenses reduce to minimum.The monolithic that is assembled in the micro switch of opening the door and close the door among the same row arranges to be the most effective arrangement form and can make wiring minimized.
The ON/OFF of electrodynamic type door
Below with reference to Figure 19-20 and in conjunction with the patent specification of referring to previously of having announced, door bolt bolt and the operation of door bolt pawl with respect to the door motion are described.
As shown in Figure 9, fastening bolt 11 with a bolt or latch can have recess 13 and 14 around door bolt eye 10, and the full door bolt that is respectively applied for pawl 20 ends with half door bolt and ending.Door bolt bolt 11 under spring-loaded clockwise trend go to open position, and pawl 20 inhour trend (B5) under spring-loaded goes to the latched position of will the door bolt bolt-lock living.Motor 70 is exported to rotation output actuator 50 by measuring gear and helical gear with rotation, and the latter is arranged to rotate according to direction D1, makes its eccentric protruding lock 30 of locating go and seek refuge with pawl 20 and makes it move to its lock position of taking off along direction D2.When continuing when the D1 direction is rotated, after door was closed, lock 30 allowed pawls 20 to rebound along the D5 direction, pinned once more and fastened bolt with a bolt or latch.
Obviously, for example, adopt helical gear or spur gear can realize that also the output of another kind of form drives coupling.In addition, pin 30 also can replace with the cam gear that any form abuts against pawl.
In said structure,, be opened under the effect of the power of the seal of Men Zaiqi elastic deformation in case described pawl moves to it not during latched position.The spring biasing of this door bolt bolt 11 also helps opening of door.
The another kind of form of door opener is shown in Figure 10.The output of motor 70 drives the form of getting rack and pinion system 31, with the part tooth bar pawl 20 that reclines, produces Linear Driving along direction D1.In case when being detected breech lock and moved to its full position of throwing off by electric power, motor or disconnection or by backward rotation take back tooth bar 31 to its neutral position shown in Figure 10.When motor cut off the power supply, tooth bar remained on its opening position and closes until the door pass.Closing of door causes pawl to go to its breech lock bonding station, drives tooth bar simultaneously and returns its neutral position.At this moment by spring make pawl 20 moving partially.
No matter be said motor outage or backward rotation, the detection of door bolt bolt position also is applicable to arrangement form among Fig. 9 naturally.
Arrangement form among Fig. 9 and 10 is applicable to the side door of automobile.It is that they have only a dimple 13 complete lock-bit door bolt bolts usually that tail-gate and luggage compartment door bolt bolt are different from described.In addition, obviously various arrangement of gears can be arranged.
Door bolt pin device shown in Figure 11 is used for the situation of being closed the door and being opened the door by electric power by power.Like this, this kind device is the open/close mechanism that power is provided by same motor 70.This motor drives rotary calibration and actuator 50 according to direction D1 or D4 selectively.The neutral position as shown in figure 11 of calibration and actuator 50 leaves the position of latch 11 corresponding to pin 34.Calibration and actuator 50 can be by inclined to one side rotatably its neutral position of trend of torsion spring 36 coaxial mounted with it, the constraints that is subjected to being fixed in the bar 35 on the breech lock casing simultaneously.Torsion spring 36 has two wing member 33a and 33b to be coupled on the opposite flank of cam pin 34.Like this, when parts 50 moved towards to drive according to direction D inhour, pin 34 drove the wing member 33a of torsion spring and impels parts to return neutral position in opposite direction.Accordingly, the motion D4 of inhour trend is short causes the wing member 33b displacement that pin 34 makes torsion spring parts 50 is returned once more.
In the last example, pawl 20 take off lock or pine oil is to realize by an actuation plate 38 indirectly.This actuation plate 38 rotatably is connected on the pawl 20 in position shown in the label 40, and the while is by the protruding pin 32 and parts 50 couplings of its deep-slotted chip breaker 39 and parts 50.The deep-slotted chip breaker 39 of actuation plate 38 is concentric with parts 50, and its function allows parts 50 to move towards D1 along inhour to relatively rotate about 70 ° and be used to close the door and interference-free.
The adjutage 37 of door bolt bolt 11 is projected into and is used on the parts 50 combining with pin 34 selectively.For door is closed, pin 34 is urged to position A along direction D1 inhour trend, and by manually that door section ground is closed, door bolt bolt 11 will arrive this position at this.To sell 34 batches and come to and above the adjutage 37 it is urged to its full lock along direction D3 and closes the position, just finish the operation of closing the door.In case the door bolt bolt detects when being fully sealed going up by electric power, makes the said motor outage and by torsion spring 36 described revolving part 50 is brought back to its neutral gear position NP.
In order with electric power door to be opened, motor moves towards ground driving cam pin 34 along direction D4 inhour, impels cam pin 34 end of tractive groove 39 immediately, thereby along direction D5 tractive pawl 20 it is thrown off along direction D6.Then, when direction D8 broke away from doorframe, the door bolt bolt just flicked along direction D7 at door.In case detect this door bolt bolt when having reached its full disengaged position by electric power, just make motor outage revolving part 50 its neutral position NP that then rebounds.
Above-mentioned electric power position sensor suitably is located in the breech lock, for example makes to prevent that it from falling into its half latched position at dimple 14 when pawl 20 is driven to its disengaged position.
This device can be contained in the casing, and so just compactness is produced with being convenient to, and has improved sound insulation value and has reduced fabricating cost.
Locking devicen among Figure 12 is the modification of installing among Figure 11, is used for the ON/OFF of door.In this example, the actuation plate 41 that replaces plate 38 is arranged to and can be slided on the rotation 43 of rotary calibration and actuator 50; There are a groove 45 these plates of guiding to move on the plate 41 along axis 43.Actuation plate 41 has outstanding cam pin 34 tops with revolving part 50 of an end flange 44A to close downwards.Actuation plate 41 can slide between position C and C1, and these two positions correspond respectively to the sealed and disengaged position of pawl 20.
Move towards D3 and turn at position A place to touch to close and make door close and drive this to sell by making cam pin 34 be docile and obedient hour hands to position A1 with door bolt bolt adjutage 37.Behind the LAP that surpasses some A1 slightly, pin 34 is thrown off with the door bolt bolt and is forwarded the second neutral position NP2 to along direction D3.Like this, the first neutral position NP1 just just has been positioned at pin 34 in conjunction with before door bolt bolt adjutage 37 places.The second neutral position NP2 then be positioned at just surpass A1 but its can with a bit locating before flange 44A engages.In case be separated from the door bolt bolt, after pin 34 is subjected to the control outage of suitable electric power position sensor (not showing bright) at motor, by the device of elastically deformable for example spring (not shown) make it stop at its second neutral position NP2 place.This motor can also stop at second neutral gear position by make its controlled driving according to rightabout.
In order by electric power door to be opened, energising makes pin 34 drive upright some 34C from its neutral position 34B along direction D3 to motor, and touches with actuation plate 41 herein and close, and at point of arrival C1 place, described flange is just along direction D7 in-position 44B.This just makes pawl go to its complete disengaged position along direction D4, allows the door bolt bolt to rotate simultaneously along direction D5 and leaves the door bolt eye along direction D6.Pin 34 continues to arrive its first neutral position NP1 along same direction.
At arbitrary neutral position, door bolt bolt and pawl fully can by manually according to conventional mode they latched position and disengaged position between driving freely.So just provided a kind of safety measure of meeting mechanical type override of anti-power failure.
Form contrast with the structure of Figure 11, although rotary calibration and actuator 50 its motions can be braked or do local counter-rotating by reversing Vidacare corp, this part is one-directional rotation basically.
Arrangement form among Figure 12 has the compactness that is associated with device among Figure 11 and the advantage of sound insulation.
Modification shown in Figure 13 provides with same motor carries out the device that electric power opens the door and closes the door.In this example, export driving in the rotation of rotary calibration and actuator 50 and be transformed to linear movement by rack and pinion gearing, a tooth bar 56 and a shuttle form integral body, and it has an end binding face 55 to be used for door bolt bolt adjutage 37 joints.At the other end, tooth bar is connected in label 57 places on the disc spring 58 on the framework 59 that is installed on the breech lock casing, is used to compress and stretch.This disc spring is used for making above-mentioned shuttle to turn back to neutral position NP and absorbs vibration and reduce noise.
Tooth bar 56 is connected on the actuation plate 52 by the pin 54 that is arranged in groove 53, makes described shuttle can the drive bolt bolt close the door and interference-free.Actuation plate 52 is rotatably connecting pawl 20 in label 51 places.
For the device in Figure 11 and 12, power driving mechanism is to operate mutually independently with traditional mechanical latches, like this, can control this pawl by door handle when pawl is in its neutral position NP.
So, to open for making door, shuttle or claim tooth bar 56 just to be urged to its extreme position P1 from its neutral position along direction D3 makes the motor outage afterwards and tooth bar 56 returns its neutral position.By this shuttle is urged to the second extreme position P2 according to reverse D5 from neutral position, traction actuation plate 52 and the above-mentioned pawl of pine oil can be realized being opened the door by electric power.
Said apparatus is owing to there is bigger gearratio can adopt less CD-ROM drive motor.
The another kind of modification of the open/close mechanism of above-mentioned car door is shown among Figure 14.Replace rack and pinion system, can drive a wire shuttle 71 along arbitrary linear direction by the cam pin 34 of rotary calibration and actuator 50, can be according to concrete situation along direction D1 or D2.Cam 74 location of cam pin 34 relative fixed on shuttle 71 makes driving to carry out in for example about 40 ° of the limited anglec of rotation scope of revolving part 50.Shuttle 71 is moving partially to its neutral position by the drawing-pressing spring 72 that is installed on the framework 73.Shuttle 71 has an end construction 78, leans position door bolt bolt adjutage 37 drivingly and makes it move to position B by position A.Open the door in order to carry out electric power, be provided with plate 52 corresponding actuation plates 77 shuttle 71 is connected with pawl 20.Identical with the device among Figure 13, have on the shuttle 71 in the groove 76 of pin 75 in actuation plate 77 and slide.
The device of Figure 14 has the advantage of flexibility in addition, can make driven wheel more easily move to its neutral position when driven by power is interrupted prematurely.
The another kind of device that electric power opens the door is shown among Figure 15.In this example, shuttle 83 is driven by the lead-screw gear of getting screw rod 81 and internal threaded nut 82 forms, still is constrained to linear movement.Leading screw 81 is driven by the helical gear 80 that rotation output drives.This shuttle is similarly drawing-pressing spring 86 inclined to one side its neutral positions of trend.The groove 84 that is coupled on the pin 85 of pawl 20 provides enough degree of freedom, describedly before allowing to be same as is independently opened the door by mechanical system.The facility of not closing the door in this example, but obviously the device in this example can be incorporated in the closing device of Figure 12 for example and 13.Device in this example is simplified, and only provides a neutral position A and a start position B for shuttle 83.
This device also had in all stages that electric power opens the door makes mechanical opening-closing door electric device advantage fully independently therewith.This device also has and can use than the advantage of fractional motor because high gearratio is arranged and compliance is extremely strong and most simple advantage.With in the past described identical, drawing-pressing spring 86 provides a kind of backlash eliminating equipment, can close down the inertia of back absorbing mechanism and reduce noise at motor, so just can prolong the life-span of driving mechanism.
Show another modification of understanding the car door open/close mechanism among Figure 16.Shuttle 95 in this example is done to drive linearly by two extension springs that separate mutually 97 on the leading screw 96 that is located between two fixing carriages 99 and 200 and 98 s' above-mentioned leading screw.This leading screw is driven by the helical gear 80 that motor 70 drives.Actuation plate 91 is connected on the shuttle 95 by the pin 92 that slides in groove 94 equally, and shuttle 95 has a binding face at 93A place, its end.This shuttle is bolted between this closed fully position B in the position of this disengagement C and limes superiors position 93A and door bolt at neutral position 93B, position A, lower position 93C, pawl and moves.
Being preferably in respect to leading screw 96 with shuttle 95 integrally formed nuts 95 and screw rod 96 is 45 ° of engaging tooth otch of locating to have them, gets so that shuttle and leading screw can drive mutually.Be used for retraining the device that nut 95 moves linearly and get any suitable form, for example be fixed in the form that the groove and the track (not shown) of integral body were gone up or become with it to breech lock casing (not shown).
Spring 97,98 can replace by being used as with the stage clip of nut 95 couplings or the single spring of extension spring.This spring also can be the torsion spring coupled with driven wheel.
Identical with previous device, adopted the electric power position sensing to control and powered to motor.Can combine with above-mentioned control device and adopt a kind of current sensor as indicating the indicator that this door bolt bolt has for example arrived its latched position, this is because have only the rising that just has electric current above this latched position.In addition, power-actuated polarity can be reversed provisionally to offset the inertia of moving component.
The advantage of the advantage of this device and Figure 14 and 15 shown devices is suitable.
For any device shown in Fig. 9-16, can on the rotation output driving shaft of motor 70, a clutch mechanism be set, the centrifugal clutch that this is preferably traditional.It is the induced-current that mechanism components produces when driving therein that such clutch can be eliminated motor, also helps simultaneously to reduce to be used for making clutch mechanism return load on the back-moving spring of its neutral position after the motor starting.
The another kind of modification of the door open-close locking devicen of above-mentioned electric power is shown among Figure 17.In this example, actuation plate 202 is to be rotatably connected on the pawl 20 in label 203 places near the binding site of door bolt bolt 11.This actuation plate 202 is tied and rotates around the axis of rotation of rotary calibration and driving mechanism 50, or by means of having at the end fork part of the wing member 205 of this each side of axis of rotation and 206 and can moving linearly along driving direction D4.
In the above-mentioned example, cam pin 34 replaces with all whole with 50 one-tenth of revolving parts and is located at two perpendicular to the radial cams on two planes that separate mutually of above-mentioned axis of rotation.On first plane, radial cams 207 be arranged to selectively against and drive bolt bolt adjutage 37.On a plane that separates mutually, radial cams 209 and opened about 100 ° in 208 minutes engages the lug 204 that dangles on the actuation plate 202 of aperture of door respectively and is fixed in W shape sheet spring 210 on the breech lock casing.Sheet spring 210 has prevented the loosening of locking devicen and has made it to be positioned on the illustrated neutral position.
For door is closed, can move towards to drive revolving part 50 clockwise and cam 207 driven arrive on the door bolt bolt adjutage 37 as previously mentioned along direction D1.In order to borrow electric power that door is opened, revolving part 50 can be driven from its neutral position along direction D1 equally, combine with lug 204 and make actuation plate 202 along direction D4 driving and pawl is thrown off.
When driven by power was interrupted because of any reason, the sliding spring (not shown) of utilization and driven wheel coupling brought back to driven wheel its neutral position.So just having guaranteed has mechanical completely control device when power failure.
The important part of the locking devicen of Figure 18 has been to illustrate uses a motor 70 and rotary calibration and driving mechanism 50 open/close mechanism of control gate independently on the one hand, is controlling electrical caging on the other hand.This open/close mechanism comprise be restricted to move linearly and with the shuttle 215 of tension and compression spring 218 couplings, as the front with respect to as described in Figure 14.Revolving part 50 has single cam pin 34, rotates along direction D1 or D5 between two neutral position NP1 that the latter can be kept by W shape fixing spring 220 and 219 respectively at it and the NP2.Actuated piece 222 is restrained between position C1 and the C2 and moves linearly along direction D11 or D22, and has in its end and to be used for the toggle link 221 that combines with cam pin 34.Toggle link 221 can be got the back with respect to the described the sort of type of Figure 35.It is rotatably mounted on the end of actuated piece 222, and be torsion spring 223 moving partially to its perpendicular to this actuated piece length to neutral position.This device can make cam pin remove to drive actuated piece 222 against toggle link 221 along direction D11 drivingly, then at the torsion of this toggle link 221 resistance springs and elastic deformation release after, cause this cam pin and can continue it and rotatablely move.In this example, this actuated piece 222 can move for cam pin is driven into along any direction in above-mentioned two directions.
For the W shape spring 210 of Figure 17, when above-mentioned pin is positioned at can be when either direction leans the outer wing of described spring, spring 219 and 220 just has the function that can absorb rotary impact.Then, cam pin just moves to and is located between two outer wings, is in the drop-center.This has just prevented and can accidental transfinite.
Utilizing actuated piece 222 to carry out electronic locking a door and open the door is described in more detail below with reference to Figure 24,26,30-38.Briefly, this actuated piece will interact with a key mechanism and untie and pin pawl 20 selectively, in order to prevent or to allow the driving of door handle etc. to pass to pawl 20.
A kind of modification of door-opening mechanism is shown among Figure 18 A among the Figure 10 that similarly provides electrical caging and unblank under same motor 70 controls.In this example, become whole rack and pinion system to pass through binding face 231 driving claws 20 with a linear shuttle.Pawl 20 has an extension rod 232 and is subjected to binding face 231 or drag-line or miscellaneous part driving by being connected with breech lock locking mechanism (not shown).There is a drawing-pressing spring 235 similarly described shuttle to be displaced to neutral position N.
When carrying out electrical caging, the dimple 234 in the above-mentioned shuttle combines with the end 1814 of bar 1810 selectively, and this bar 1810 rotates around its pivot 1812, and moving partially to illustrated neutral position by the torsion spring 1813 on this pivot 1812.The relative wing 1811 is coupled in the dimple of the actuated piece 300 that can move along either direction D7.
Figure 18 B shows open/close another device of understanding door, and it is with similar below with reference to the described device of Figure 33.Revolving part 50 directly acts on and acts on simultaneously on the pawl 20 with an adjutage 20A on the door bolt bolt adjutage 37.Cam pin 30 is offset to its neutral position N for the spring 1802 around a steady pin 1801 location.
To push position B at the adjutage 37 at A place by driving cam pin 30 pacifies now and closes the door; Make cam pin turn back to neutral position N by spring then.Press the rightabout CD-ROM drive motor, cam pin 30 moves ejection pawl 20A along direction D2 and removes pine oil door bolt bolt.This cam pin can borrow electric power or back-moving spring to be back to its neutral position once more.
In this example, the far-end 20A of pawl 20 can be able to door bolt bolt adjutage 37 is carried out override by crooked the rising.
Above-mentioned special device can reduce driving moment makes it have more flexibility.
Under electric power, carry out the ON/OFF of door
Device among Figure 19-21 can be opened the door by electric power, wherein at first pawl is released, and the drive bolt bolt is opened fully to guarantee it under electric power then.This device also provides and the identical function of being closed the door by power of aforementioned those devices simultaneously.
At first referring to Figure 19-21, door closing device comprises a door bolt eye 10 that is connected with doorframe and forms the door bolt bolt 11 that is supported on the locking devicen part on the car door door limit.Though the shape of door bolt bolt 11 is that the present invention is distinctive, its general function then belongs to conventional and needn't describe in detail at this.Door bolt bolt 11 is rotatably mounted in label 15 places, can be driven and showing to rotation by arrow 18 by the relative motion 17 of door bolt eye 10 in the U-shaped dimple 12 that forms in the door bolt bolt 11.Door bolt bolt 11 also is formed with two other dimple 13 and 14 and is used for and locks pawl 20 and combine on its periphery.Dimple 13 is used for the door bolt bolt-lock is scheduled sealed turned position, and it maintains door bolt eye 10 and continues closed door simultaneously.When pawl 20 is released from its latched position dimple 13, allow door bolt eye 10 drive bolt bolts 11 under the cam-type effect of breach 12 by moving towards 18 drive bolt bolts 11 clockwise, until door bolt bolt 11 during, the right side in Fig. 1 is beaten no longer for 10 detentions of door bolt eye.If but allowing lock pawl 20 to be engaged in so-called half position latching with another dimple 14, door at this moment can be that half lock is half-open.
According to the present invention, door bolt bolt 11 is to be coupled to drivingly on the general used the sort of motor 70 of car door central authorities locking system.Relevant coupling devices will be illustrated in down in more detail and comprise that simultaneously one is used for the device of pine oil pawl 20.
The part of gear 50 has a U-shaped recess 51, and these recess 51 similar cam-type ground are against the wing of giving prominence to from the hook 32 of pawl actuator 30 ends 33.Actuator 30 is subjected to the constraint of the structure on the breech lock casing (not showing bright), generally along the showing to reciprocating motion of arrow 34, is able to be connected with the pin 23 of pawl 20 by mechanical system.The dog-leg shape is got in the upper end of pawl actuator 30, has the extension that is formed by the groove around pin 23.During connecting, the driving of this device form between pawl actuator 30 and pawl 20 provide free travel.
The operation of locking a door of power-assisted is described below.Should be realized that the operation of locking a door both can be carried out without the driving of motor by mechanical system, also can drive and carry out by motor.This becomes a kind of important safety feature naturally.
The dynamical type operation is described below.If door is in its make position as shown in figure 19, door bolt bolt 11 is positioned at its door bolt and closes the position and lock pawl 20 and be in its latched position.Pawl actuator 30 is gear 50 engagements.When received the instruction of opening the door by central electronic control circuit 90 after, motor 70 driven wheels 50 inhours are moved towards to rotate, shown in number in the figure 41.In first 60 ° of rotations, gear 40 keeps motionless, does not attempt to rotate door bolt bolt 11.Not so, breech lock and pawl will jams.Recess 51 shows to driving pawl actuator 30 that according to arrow 34 this just can put off pin 23 immediately and show that according to arrow 22 moving towards rotation to the driving claw inhour moves to disengaged position with it.Being rotated further of gear 50 makes the extension 33 of pawl actuator 30 play action of cam and is positioned on the periphery of gear, and can temporarily prevent entering again of claw stop 20, when being rotated further another 60 °, just can urging to cause the wall of groove 52,53 and show that along the pin 44,43 than pinion from arrow 18 to drive bolt bolt 11 touches and close.Mode is carried out power operation according to this, just can have to stop half door bolt to close preparatively.Like this, the door bolt bolt rotates and makes dimple 14 by tooth 24, combines with the tooth 24 of pawl 20 up to the external surface of fastening bolt 11 with a bolt or latch, thereby has prevented entering again of pawl.
The driving that will make motor in the electronic position sensor that the following describes is cut off when car door partially opens and takes off the bolt position by it.Then, door can be opened easily fully by passenger or driver.
Resistance door bolt eye moves towards drive bolt bolt 11 clockwise and can satisfactorily door be pushed open, and this has just quickened the opening movement of door, and this opening movement will proceed to when slowing down because of the friction of door hinge again and again, and the amount of deceleration then depends on the degree of inclination of vehicle.
When door is closed, it will arrive the same position of closing the position just above half door bolt, motor be switched on once more, but have opposite polarity (explanation of seeing below).This motor provides the operation of closing the door of power-assisted then, guarantees that car door is closed suitably and door bolt closes.In addition, by power-assisted at closing time, it is impossible that half door bolt closes the position.Along with car door begins to close fully, the rotation of the inhour trend of door bolt bolt 11 just is accompanied by than pinion 40 and than the rotation of gear wheel 50.After the phase I of this rotation, the extension 33 of pawl actuator 30 is oppositely translation down just.The free travel that pawl actuator 30 and pawl are 20 allows pawl 20 to be pressed on the groove 14 under the spring of trend moves partially clockwise and enters in the groove 13, and does not have jam.After in tooth 24 enters groove 13, this device promptly returns position shown in Figure 19.
When not having power-assisted, can control breech lock by linkage arm 25 by door handle.At this moment maintain the interaction of machinery, and the short axle that causes motor of the Push And Release of door rotates, but this only provides mechanical resistance in a small amount.Linkage arm 25 is promoted and make the pawl pine oil that door is opened, and door bolt bolt 11 just a move towards rotation for door bolt eye 10 inhours.In addition, pawl actuator 30 is thrown off the engagement with gear 50, and is closed once more until door.Should know since the mechanical linkage order identical, otherwise power-assisted close the door can agree to non-power-assisted open the door and.When the operation of breech lock is pure when being mechanical type, it just can remain in that half door bolt closes the position and place within the dimple 14 with the tooth 24 of pawl 20.This is convenience and the safety feature that has in addition.
Figure 22 shows a kind of remodeling of the device of understanding the Push And Release function that door is provided among Figure 10 and the 18A.As we can see from the figure, the binding face 231 on the shuttle 233 makes it move to position 232A by its adjutage 232 driving claws 20.The motion that continues this equidirectional will be fastened bolt extension 37 with a bolt or latch and is urged to it and take off bolt position 37A.Identical with the device among Figure 18 A, groove 234 is used for electrical caging in conjunction with one and takes off the chain bar of lock (Figure 18 A 1810).
Show among Figure 23 and understand the electric power door-opening mechanism that is specially adapted to luggage compartment or tail-gate breech lock.The rotation of motor 70 output driving mechanism 50 rigidly with leading screw 240 couplings, leading screw 240 makes a shuttle body 242 do linear reciprocating motion, this shuttle body 242 in its nut part 243, have screw thread simultaneously this shuttle body the endoporus that is used for accommodating this leading screw 240 is arranged.The pawl 20 that the end binding face of shuttle body 242 cooperates and driving is used to open the door.Identical with other devices, the part 244 of pawl 20 is connected on outside hand-control device such as the handle by bar 246 by connecting rod 245, and is feasible prior after this breech lock takes off bolt by key mechanism, interior door handle button or electric control gear (not shown), and door is opened.Nut 243 is back to its neutral position with the shuttle body after each starting, as shown in the figure, at this moment will use at least one in following two mechanisms: act on the back-moving spring on the nut; Act on the back-moving spring on the pawl, switch on so that nut moves along direction D6 for simultaneously motor once more.Nut 243 carries out linear movement by track restrained its that proper device for example is fixed on the casing.
In another kind of device form, leading screw 240 and internal thread 241 engagements of rotating in the driven wheel 50, this leading screw is and shuttle body 242 monolithic moldings simultaneously.Expert reader is when the structure that can grasp other all mechanisms equivalences.
Figure 24 shows clear a kind of door latch device that compacts.Casing 250 is got flat rectangle case shape, the bight rounding, and have the U-shaped hole that is used for installing door bolt eye 10.This casing comprises the end plate 252 and the sidewall 251 of mutual face-off, and they define an inner room 2530 that is used for accommodating motor 70 and rotation output transmission 50 and are used to control each bar 255 and 257 drag-line 256,258 and stretch out and be connected with described bar by the mastoid process that end construction keeps from above-mentioned sidewall.After comparatively ideal concrete type of attachment will be described in reference to Figure 46.
The point of relevant this device compactedness particular importance is that several parts comprise that pawl 20 all is installed on the same pivot 21.This locking devicen provides electrical caging and the function of taking off lock.
Rotation coupling part 300,400 comprises two parts, and they rotatably are connected on the pivot 21, but can carry out slip perpendicular to pivot by the avette groove that forms in these two coupling parts.Locking piece 300 is constrained on door and takes off the left-most position shown in Figure 24 of lock in this, and door since pawl pine oil bar 225 no longer and pawl 20 couplings promptly make this pine oil bar be between the right-most position of locking of neutral gear situation to carry out linear movement.Rotary slide 400 with a deep-slotted chip breaker stride take advantage of on the pin 301 of locking piece 300 and with sagging lug 262 monolithic moldings.This deep-slotted chip breaker is enough to during by lug 262 couplings, this sliding part be rotated at rotary slide 400 and pawl pine oil bar 255 with this pine oil bar.When locking piece 300 towards moving to right when it makes pawl pine oil bar neutral gear, lug 262 moves with it, makes its dimple 263 combinations of pine oil bar no longer for this reason.
Rotation coupling part 300,400 is subjected to the output panel that has cam pin 500 that the helical gear 50 for motor 70 driven and drives selectively.This cam pin drives locking piece 300 by dimple or other structures 302.This coupling devices will describe in detail with various form with reference to Figure 25,26,35-38.
For example can realize mechanical locking and take off lock by bar 257 from key mechanism or interior door handle button.This drives locking piece 300 and forces motor to drive when unpowered.So this locking devicen can provide the locking of independently mechanical type and electric power formula and take off lock.
Only show among the figure bright its a part of parts 254 also drivingly with a part of coupling of locking piece 300, be used for locking and take off lock.
Have the rotary slide 400 with the lug 262 of the fork 259 permanent couplings of pawl 20,, can make it can be not fixed and take off between lock position and move at its pin in the whole process that is driven in rotation by boss or elongate pieces 260 outstanding from casing.Because pawl fork 259 is striden and is taken advantage of on boss 260, lug 262 can not according to arbitrary radially along pivot 21 radially by boss 260.
The anti-locking of crashing
The required function that can provide anti-breech lock to crash locking is provided boss 260.Boss 260 has been because itself and radially the combining of lug 262 have stoped the slip of locking piece 300, can remain at door handle to open and pawl when being in it and taking off the bolt position, stops the accidental of door to lock.Like this, if the breech lock of door be get loose and door when being shut suddenly, this door can be not locked accidentally owing to there is rotation coupling part 300,400 to remain in the casing.
Even there is not the locking device of this band boss 260, also this locking devicen can be configured for the purpose of the anti-locking of crashing.At configuration shown in Figure 24 and in the device of Figure 25 and 26, the latched position of locking piece 300 is on the right side away from door bolt eye 10.The door bolt bolt is orientated to make closes towards left-hand.Like this, take off bolt before if be latched in to close the door, locking piece 300 will arrive the left side fully, and can any influence not arranged to its position in violent any impact at closing time.If but close the door suddenly then on the door lock, locking piece certainly will continue it left to the motion of taking off lock position and its latched position of might rebounding under this collision, yet no matter be which kind of mode, can not occur being locked into the accidental of latched position and moving from taking off.Like this, the path of door bolt orientation of bolt and coupling part 300 makes, in application, this latched position than coupling part 300 to take off lock position much far away apart from door bolt eye 10.
Electric lock optionally
Referring to 25 and 26 two kinds of different locking devicens that are used for electrical caging and take off lock are described below.Every kind of device has the outside manual overvide that two pawl pine oil bars 700,800 are connected to for example inside and outside door handgrip, and each such pine oil bar roughly is equivalent to earlier in respect of figures 24 described pawl pine oil bars 255.Each pawl pine oil bar respectively by himself rotation coupling part 300,400 and 350,450 selectively coupling pawl 20.Each such rotation coupling part comprises that being connected respectively to function class is similar to top with reference on the locking piece 300,450 on the rotary slide 400,450 of the described corresponding component of Figure 24.They all are provided with around public pivot 21, and maximum compactedness and terseness is provided, and have sufficient leverage simultaneously in the time of making pawl pine oil bar in machine is packed casing on pawl 20.
In addition, each locking devicen depends on that it is used for back door or Qianmen, also has other lever 900 to be connected to the outer mechanism that controls by drag-line 901, for example on children's safety switch or the interior door handle button.This lever of establishing in addition 900 has fulcrum 902 in casing, and by with rotation coupling part in a suitable end pin 903 that is connected be connected on the lever arm.
In device shown in Figure 25, locking piece 300 and 350 has protruding pin 304 and 305 separately, and the latter cooperates with cam pin 501 on rotary calibration and the actuator 500.In Figure 25, these two locking pieces drive according to rightabout independently, and in device shown in Figure 26, they can be driven together, move back and forth along direction D7 and DB, and they also can alternately drive independently certainly.Figure 25 and 26 locking devicen have sufficient flexibility, can be used for children's safety locking and/or emergent opening the door, and can be selectively with one or two combination of exterior door handle.They also can form integral body with electrical caging mechanism, by same or different motor control.
In the situation of Figure 25, for example when being used for the Qianmen, exterior door handle can link to each other with pawl pine oil bar 700 by drag-line 701, can be locked by interior door handle button by lever 900 simultaneously.But for the back door, thisly should get opposite mode, and lever 900 will become and redundant maybe can be used as mechanical children's safety bar with the connection of door handle.
Device among Figure 25 operates as follows.As shown in the figure, rotation coupling part 300,400 leaves dimple 803 and lug 410 leaves between the right-most position of dimple 453 and drives lug 410 and 420 at left-most position and lug 420.Lug 420 permanently is matched with in the jaw of pawl fork 259 on the pawl 20.
Rotation coupling part 350,450 has the lug 451 that can move towards driving for 702 inhours of the dimple on the pawl pine oil bar 700 in its left side.As mentioned above, it also can rotatably be connected with lever 900 by pin 903.Rotary slide 450 is formed with an energy moves towards driving for 802 inhours of the lug on the pawl pine oil bar 800 dimple 452; It also is formed with dimple 453, drives at its lug 410 in other rotary slide 400 of leftward position.
The starting of bar 800 directly drives lug 420 by dimple 803, but when just thinking that rotary slide 400 is in its illustrated left-most position.Even if this is with driving pawl 20.
So long as rotation coupling part 350,450 is when being in the left-most position (not shown) of its neutral gear, bar 700 also can be in neutral position, and can affact effect on the dimple 452 of rotary slide 450 with its lug by another pine oil bar 800, get back to its illustrated coupling position automatically.Like this, when wherein interior door handle has placed neutral position by the children's safety bar if for example handle outside door handle on latch, just can make when operating the interior door handle afterwards and open; In other words, the operation of outer handle can be carried out override to the children's safety function.Similarly, this device can be with the emergent override of door locked, can be before operation be inner during door handle, make the interior door handle button of 800 liftings of bar and lever 900 couplings.
The operation of installing among Figure 26 and Figure 25's is similar, and these two rotary slide the 400, the 450th just are and in right-hand pawl fork collaborative work of device.Corresponding parts indicate with identical reference number.Figure 26 A has generally shown and has installed right-hand detailed structure.
Said apparatus is automatically controlled owing to being carried out the selection operation of interior door handle by the electronics central control unit, can not need mechanical children's safety bar.Can open exterior door handle as mechanical override, be used for police car and be used for the children's safety purpose to this to interior handle.
Said apparatus for example can realize by making the interior door handle button that is connected with lever 900 place neutral gear that twin-lock is fixed.Like this, only just can control the selection locking of the fixed inside and outside handle of twin-lock and carry out children's safety control with single-motor.By independent control interior door handle selectively, even also can realize the children's safety locking of electric power without any mechanical device independently.
Existing latch needs many mechanical parts and usually will be with two motors surely in order to carry out twin-lock.
Playing the function that merit temporarily is obstructed back continuation locking or is taken off lock because of the mechanical type door handle.
Figure 25 and 26 pawl pine oil bar 700 are to be shown in certain neutral position 700A place, and the pawl pine oil bar 700 of Figure 27 then is the situation that is shown in its position 700B that starts fully.During starting, at position d, the lug 420 of corresponding rotary coupling part can only be partly drives coupling position 420C to it can lock from its neutral position 420A that takes off lock.This be since lug at label 420B place against the edge of bar 700 firmly.In case door handle releases and turns back to position e, dimple rises to position 702A, and lug 420 promptly freely moves to the position 420C of its complete coupling from position 420B.Even for the effort when initial also can continue after being subjected to blocking this from B to C to left movement, can switch under the control of central lock controller 90, for motor again.But available another mechanical device provides mechanical elasticity power to produce moving partially and lug is directed into 420C from 420B.A kind of eccentric spring assembly is preferably arranged, and its unsettled center is corresponding to the halfway position of lug between position 420A and 420C, and the right-hand of the centre position 420B that closes slightly touched at this lug and bar 700 in this halfway position.Like this, this lug moves until arriving its half-way towards right avertence; Surpass this half-way, lug promptly is offset to left.The eccentric spring assembly of this class is known, normally utilizes the torsion spring that is connected with casing with lug respectively with its two ends.
The rotary slide 400 among Figure 25 and 26 and the another kind of configuration of pawl 20 are shown in Figure 28.The fork part is formed on the rotary slide 400, has the yoke 430 and 431 of different length, and no longer is located on the pawl.Be formed with the sagging pin 20A that is coupled in the fork on the pawl.Facilitate the independent sealed or isolated of rotation coupling part and each bar like this, they can seal with driven wheel and motor together.Utilize the device form among Figure 28, pawl and the easier assembly with this sealing of door bolt bolt separate, and this is because pin 20A can be by a sealable hole in pivot 21 upper casings.So just can obtain better soundproof effect, also owing to the life-span that can improve the breech lock actuated piece with other abrasive materials without gravel.
Electromechanical children's safety device
The electromechanical children's safety device that is used for aforementioned locking devicen is shown in Figure 29.Independent motors 70 drives one by the slide block 191 that is supported on label 192 places by groove 193 rotatably and supports the bar 194 at label 195 places rotatably.Slide block 191 is tied and moves linearly, and is subjected to the driving of the leading screw 198 that motor thus drives by reduction gearing.Bar 194 has a pin 196 to be connected to and can to do to operate this child safety mechanisms on the actuator lever 197 of reciprocating linear motion along direction D3 and D4 between position c and the d at its rounded end.As mentioned above, can make the coupling selectively of this mechanism and pawl like this, be used for making selectively the interior door handle to throw off.This automatically controlled mode does not need mechanical children safety pole or the switch in the latch of back.
The electric power formula locking of combination and the Push And Release of door
Figure 30-38 shown device can be with the standalone feature of motor control locking devicen, as the locking of electric power formula door with take off lock (central authorities' locking) and open and/or close.Invention and other devices of several novelties are disclosed.
Locking devicen among Figure 30 has a rotary calibration and actuator 50, and this actuator 50 has a cam pin 30 that two neutral position NP1 and NP2 arranged, and the spring 100g that uses for shock-absorbing loads and enters above-mentioned position.The lever arm 1001 that has the operation of control to start independently to be used to lock a door along direction D1 and D2 and the cam of a shuttle mechanism 1006 refer to 1004.In order to carry out electrical caging, can come dwang 1001 along direction D11 or D12 resistance reduction torsion spring 1002, start this suitably simultaneously to locking piece 300 and 350.As shown in the figure, depend on the rotation direction of cam pin 30, the cam 1003 of bar 1001 forwards one of two extreme position C1, C2 to from neutral position C.
Realize opening the door by having a shuttle 1006 that acts on the bonding surface 1005 on the bar 1008 of pawl 20.In order to close the door, the binding face 1010 of shuttle lower end makes it move to position B1 from position B against door bolt bolt extension 37 thus.As shown in the figure, cam refers to that 1004 move between neutral position NP and extreme position P1 and P2.As hereinbefore, above-mentioned shuttle is by 1007 controls of tension and compression disc spring.
Device among Figure 31 has shown the single cam on rotary calibration and the actuator 50 refers to how 1012 control three kinds of functions selectively: 1010,1011 displacements of two such bars that the single rod member 1001 among Figure 30 is provided with around revolving part 50 for equal angles ground.Cam refers to that 1012 have three neutral position NP1, NP2 and NP3, and it is subjected to bright device not shown in the figures and makes spring-loaded.So just can control two locking pieces 300 and 350 as shown in the figure independently.
Another modified example is shown among Figure 32, wherein refers to that by cam 1012 drive the 4th actuated piece selectively, and these four actuated piece 1020-1023 equal angles ground are provided with around revolving part 50.Like this with regard to can one motor control the selectable locking of two handles and carry out the Push And Release of door by electric power, as shown in figure 31, and miscellaneous function such as children's safety operation.In the variation of the device of Figure 32, can also different cam 1012 (not shown) for example be set what revolving part 50 separated vertically on the Different Plane on the camshaft, to improve the flexibility of repeatedly starting operation.
Another variation shown in Figure 33 is specially adapted to tail-gate or luggage compartment breech lock.Single cam pin 30 is by coaxial mounted with pawl, and disposes a flange that dangles 1031 and drive this pawl and freely rotating and the swingle 1030 of inoperative this pawl along direction D7 along direction D3, comes driving claw 20.Like this, this cam pin 30 can rotate dwang 1030 clockwise with moving towards and can not be subjected to the obstruction of pawl along direction D6.Cam pin 30 also start lever arm 1034 handle by connecting rod 1033 also with the locking piece 300 of key mechanism coupling.This locking mechanism makes handle or button and pawl 20 couplings selectively by linkage 245.
Identical with other devices, revolving part 50 can by spring-loaded for example by sheet spring 1037 radially to the turning arm surface of bending of reinforcing enter its neutral position.
Figure 34 shows that clear this cam pin 30 can be arranged through suitable pin or projection 304 and 354, drives two sliding pins respectively and decides part 300 and 350.Projection 354 can move between position A, A1, A2 and A3 by cam pin 30, and projection 304 can move between position B, B1, B2 and B3 accordingly.The settling position of projection 304,345 is to be the position shown in A1, A2 and B1, the B2 on dotted line, and these two projections move between these positions by cam pin 30, and cam pin 30 by after turn back to these positions.In order to allow cam pin 30 to pass through, they can move on to corresponding extreme position A, A3, B and B3 flexibly outward.As an example, as shown in figure 35, in order to try to achieve above-mentioned elastic reaction, can make the projection on the locking piece 300,350 get the toggle link form, this toggle link 1050 is located at fulcrum 1052 places rotationally, and moves to its middle position partially for being located on this fulcrum and by the torsion spring that a fixture 1504 is kept.This toggle link or refer to that 1050 rotatably are moved to position P1 will be brought back to its neutral position P by spring arm 1051 at this.Similarly, it can be displaced to position P2 and be brought back to its neutral position by spring arm 1055.
Other alternative elastic constructions also can be arranged naturally, and as shown in figure 36, cam pin 30 is regularly, is arranged on the box structure one V-arrangement sheet spring 1070 that remains on actuator 1080, and this actuator for example is the part of one of locking piece.In addition, as shown in figure 37, pin or button are installed, make it to be depressed and cooperate cam 1083 to pass through at the set up procedure relief that rotates in order in the casing of arbitrary actuator of revolving part 50, to slide.
In the structure of Figure 38, a rotating cam 1083 engages with flexible slender arm 1081 and 1082, and the latter two can revolving part 50 radially make elastic deformation, thereby after the rotary-actuated stage, can allow this cam 1083 to pass through.
Key operation mechanism
Be applicable to the operation of key mechanism of the locking devicen of Figure 25 for example and 26 below referring to Figure 29-44 explanation.The key mechanism that is typical column has rotation output, and they need be transformed to for example linear displacement of locking piece 300,350.This is to be realized by the special cam disc that forms 5000 that is set to the driving of key mechanism.In the device of Figure 39 and 41, this cam surface is urged to cause locking piece and is done relative linear movement; In the device of Figure 40 and 42, this cam surface is facilitated equidirectional linear movement.Under various situations, described device allows identical locking piece to carry out the machinery starting independently.
Shown in Figure 39 and 41, cam disc 5000 has wedge shape among each of four quadrant district 41-44 cam surface in the plane of this dish, ramps up to a high position reposefully from low level, and radially separating with the plane of dish is enough to the air line distance that makes the locking piece displacement required.In this example, the quadrant of the radial symmetric of cam surface is on the opposite face of this dish.In Figure 40 and 42 corresponding example, the relative sector of cam surface then is on the same one side of dish.Region D 3 among Figure 39 and 40 and D4 are representing the direction perpendicular to the plane of dish 5000, and locking piece promptly moves along this direction.
During operation, described key is docile and obedient hour hands or inhour and is moved towards driving-disc and turn over 1/4 and change, and this motion then is transformed to the corresponding rectilinear motion of locking piece 300,350 by the slope of quadrant.
Above-mentioned locking piece also is shown in Figure 43, and it moves according to relative direction when locking piece wherein starts corresponding to the system of Figure 39 and 41.The adapter 2007 that is carved with cylindricality keyway 2006 is used for driving this transforming disk 5000 through coupling, and this dish can be driven by the key 2001 that has splined end 2005.In this device,, allow angle tolerance to surpass a tapering 2003 by the splined end 2005 of arc.This key drives diskware 5000 along suitable direction of rotation immediately along the rotating drive adapter 2007 of direction 2004.
