The known drive systems of the stopping sliding door especially show as guiding system.In this case, turning arm and phase are passed through Close orbit of guide rail define the door leaf pivot and sliding motion.However, the gate driver its end is not locked at In position, but the other fastening system by acting on the door leaf edge locks the door.

Especially, the fastening system of such known type crosses dead-centre position with component, so as to which vehicle doorn be maintained at Determine in position, it is, especially, preventing the door to be opened due to the pressure that vehicle interior applies.However, therefore The door that can prevent from opening inadvertently closes.For example, the B4 of patent DE 199 58 746 disclose a kind of vehicle turnstile Retaining mechanism, the door should be kept in the open position by such mode.When the storing cycle go up a slope or under Slope, during with the turnstile in the open position, this door leaf for prevent to open is because its own weight is on its rotation Axis rotates related rotary shaft so as to which door whereabouts closing is possibly realized.This by connecting rod and the connecting-rod bearing in drive shaft The turning arm is connected in cam disc and realized.When opening the door, the connecting rod and the connecting-rod bearing are crossing dead point In position, and the connecting-rod bearing was increasingly pressed into dead point in rotary shaft during being moved on the direction for closing the door Position.In this way it is possible to prevent the door from inadvertently closing.However, if the door is closed intentionally, then driving Apply torque on axle, so as to rotate the cam disc being disposed thereon.It is described that this also make it that the connecting-rod bearing is pivoted out Cross dead-centre position.

In addition, for example, the U1 of utility model DE 20 2,005 015 169 description one kind has support rails and locking device Stopping sliding door (sliding plug door), it can be easily installed and adjust.In this case, dead point or excessively dead Point retaining mechanism is also used for preventing the door of closure from inadvertently unlocking, for example, due to sharp pounding or impact.This is along with passing through The locking plate that lever system and coupling bar are connected to motor shell is realized.On the motor shell drive axis Be rotatably mounted the motor shell, so as to by the reaction force of the motor by the coupling bar and The lever system is delivered to the locking plate.The locking plate, which has, is characterized as locking slot, by using the motor Reaction force the locking plate is rotated in a position so that by the door locking, clamping screw is with this described in the position A kind of mode of sample is located in the groove：The door can not move in the moving direction of the support rails.In the closing position In, the dead-centre position of crossing of the lever system prevents the door from opening, wherein, this by the clamping screw in addition with being realized Retaining mechanism is fixed together.

It is reliable in actual applications that such retaining mechanism, which turns out to be, but depending on the shortcomings that it is with intensively and carefully working out something phase The design of pass.For example, the different rotatable mounting assemblies of retaining mechanism must not be not connected to the opposite side of bottom plate.Especially, phase When thin plate and with low height bearing for the purpose, so as to prevent the vertical dimension of the retaining mechanism more than a scale It is very little.In addition, bearing bolt is connected to the bottom plate by way of welding.

Therefore, the present invention is based on the lock for manufacturing a kind of available vehicle especially stopping sliding door of the vehicle of public passenger transportation The target of tight device, it operates along with maximum reliability and can easily produced.

According to the present invention, the target is realized by the locking device according to first aspect.It is public in a preferred embodiment Open the favourable advantage of the locking device.It is in addition, real by the stopping sliding door with such a locking device according to second aspect Existing target defined above.

On this point, it should be noted that the personal feature quoted in claim can be with any technically rational Mode is combined with each other, so as to form the other embodiment of the present invention.In addition, the description represents the spy of the present invention especially with respect to accompanying drawing Seek peace and illustrate the present invention.

The creative locking device is suitable to the stopping sliding door of the vehicle of vehicle especially public passenger transportation, wherein, should Door includes at least one door leaf that can be transferred on the longitudinal direction of the vehicle and moved between closure and open position Move the driver of the door leaf.In this case, the locking device includes bar assembly, and it can be introduced into dead-centre position In (over-dead-center position), so as to lock the door in the closing position of the door.

According to the present invention, the locking device, which has, is characterized as bottom plate, and latch and bell crank exist on the bottom plate It is rotatably installed in the plane extended parallel to the plane of the bottom plate in respective bearing.In the context of the present invention In, term " parallel " feature is only in that the latch of relatively described bottom plate and position and the rotary flat of the bell crank Face, but do not need the absolute parallelism of these components relative to each other.In addition, the bell crank and the latch by with Be hinged mode is separately mounted to locking lever on these components and is connected to each other, wherein, due to be hinged, the energy of the locking lever It is enough that the bell crank, the locking lever and the latch are introduced into a position, the bell crank described in the position The connecting line and both arms song between joint (joint) between the bearing and the locking lever and the latch The connecting line between joint between the bearing and the bell crank and the locking lever of handle in dead-centre position is crossed, Wherein, dead-centre position this can be crossed by the reversely be hinged release of the locking lever.Therefore, by the bell crank and described Locking lever was introduced in dead-centre position, and so as to lock the door, but the latch is simultaneously rotated and can be used in mending Fill locking.If it is not used in supplement locking, then it only forms the part for the bar assembly for realizing dead point retaining mechanism.

In the dead-centre position excessively of the bell crank and the locking lever, it is impossible to unlock the lock by applying pressure Tight mechanism, the especially inner side in door leaf/multiple door leafs.In this case, by the latch, the bell crank and institute State the same side that locking lever is arranged in the bottom plate.The creative configuration of the component of the bottom plate side especially has this The advantages of sample：It can therefore manufacture to obtain the closely device with easy to manufacture.Institute can be manufactured in a manner of precast segment Locking device is stated, is then installed in by the bottom plate on an entrance.Similar locking device known in the art is frequent With the rotating component for being characterized as the bottom plate both sides, wherein, repeatedly tilt the bottom plate.For example, in the plate on Individual elements make groove, breach or cave, so that the minimized height of whole locking device.If by the locking device It is arranged in the upper area of such as door entrance, then it needs only to minimum structure space in vertical direction.Because the region In generally also lay the driver with one or more orbit of guide rail, so the locking device should with simple and Section space-efficient mode supplements respective driver element.However, in some cases, such as because material thickness is often not enough to Bolt is screwed into, so the component of such as bearing can only be connected to relatively thin bottom plate in a welding manner.Only held using short axle And it is possible, it need not increase the height of the locking device.

However, it is possibly realized the invention enables the simple flat plate using no sloping portion, so as to significantly simplify the plate Manufacture.Furthermore, it is possible to the bottom plate is realized relatively thickerly, such as about 10-15mm.If for example, for installing phase respectively The bearing of the latch rotatable to the bottom plate and/or the bell crank includes the spiral shell being fastened on the bottom plate Bolt, then bolt can be screwed into the bottom plate.Furthermore it is possible to use longer bearing.The height of the bearing bolt can position In such as about 20-40mm.

The accessory 63 being arranged rigidly on the door entrance of orbit of guide rail 62 on extending in horizontal direction is passed through Driving plate 64 is rigidly connected to each other, and driving plate 64 is arranged horizontally in into the top of support rails 53 and parallel to the support rails. Motor 50 serves as driver element, to shift door leaf in a longitudinal direction, and mobile support rails and in a lateral direction Lock the support rails.For example, the motor can be made up of the electronic back-geared motor of planet.However, it also may be used The driving of other modes, such as pneumatic actuation can be used.In shown exemplary embodiments, planet belt is slowed down by helical gear 51 The output shaft of the motor 50 of gear is connected to live-roller, and the live-roller forms belt transmission together with other elements, such as instead To carrying roller and transmission belt.The rail unit is connected to by the transmission belt by actuated element 54 respectively in such a way： Their lengthwise movement produces in the opposite direction respectively.In such a case, it is possible to track roller 55 is arranged in actuated element The driver element is guided on 54 and on unshowned orbit of guide rail, so as to realize rotation-sliding motion of door.

With reference to the accompanying drawings, the back-geared motor 50 of planet is arranged in such a way：Its shell is in the vehicle Longitudinal direction extends.In addition, the shell of the motor is arranged on to the supporting that can be rotated on being directed at the rotation axis of output shaft On guide rail 53.In addition, the shell can rotate relative to the shell of helical gear 51, wherein this can be by between the insertion shell Unshowned sliding bearing, ball bearing or rolling bearing are realized.

The rotatable outer shell of the back-geared motor 50 of planet is connected to by locking device by coupling bar 52.The lock Tight device is disposed under driving plate 64 and interacted in shown exemplary embodiments with clamping screw 65, clamping screw 65 Driving plate 64 is passed upward through in the side of the locking device from top protrusion and is fixed thereon.In addition, match somebody with somebody in driving plate 64 Groove 66 is put, the bolt 41 for promptly discharging protrudes from below by the groove.Bolt 41 can be in the groove of curved shape Interior movement.

Fig. 2 shows the preferable schematic diagram of the configuration of no driving plate 64, so as to present visible underlying lock The component of tight device 10.According to the accompanying drawing, locking device 10, which has, is characterized as bottom plate 11, by the several removable of the locking device Dynamic component is arranged on bottom plate 11.Bottom plate 11 is installed on the crossbeam 67 extended between two sides bracket component 60.For example, The installation can be realized by way of slotted eye and thread connection.Latch 20 is rotatably arranged in bearing 14 On bottom plate 11.Especially, bearing 14 can be made up of the bolt for being screwed into bottom plate 11.Latch 20, which has, to be characterized as locking groove 21, above-mentioned clamping screw 65 is prominent in locking groove 21.Although driving plate 64 is not shown in Fig. 2, the figure shows cloth Clamping screw 65 thereon is put, so as to illustrate its position in locking groove 21.

Locking groove 21 can be realized by way of slotted eye, but there can also be other suitable shapes. In any case, it should select the shape in such a way：Depending on rotation of the latch 20 on bearing bolt 14 Limit or discharge the motion of the door.By this way, especially, it should by the support rails 53 in orbit of guide rail 62 transverse to The longitudinal direction limitation or release of the vehicle.In the case of shown in Fig. 2, the longitudinal axis of slotted eye 21 is approximately parallel to Crossbeam 67 extends, so as to which the door will not move transverse to crossbeam 67.If on the rotational lock in a clockwise direction of bearing 14 Plate 20, then the longitudinal axis of slotted eye 21 extends transverse to crossbeam 67, so as to which the door can move in this direction. In this case, position of the clamping screw 65 in slotted eye 21 changes.

Coupling bar 52 is configured on the shell of motor 50, so as to rotational lock plate 20 and realizes the several of locking device 10 Lever crosses dead-centre position.Because the shell of the motor is arranged on the support rails so as to which it can be in certain angle In the range of rotate, so can depend on the motor driving push coupling bar 52 open and coupling bar 52 is pulled into the shell. The free end of coupling bar 52 is connected to locking lever 30 in articulated manner, the first joint 32 is passed through with horizontal rotatable manner Locking lever 30 is consecutively connected to latch 20.In order to reach this target, locking lever 30 is slightly tilted and about existed Bell crank 40 is connected to by second joint 31 with horizontal rotatable manner on its angle point.Axle is passed through with horizontal rotatable manner 13 are held the bell crank 40 is arranged on bottom plate 11 successively.Therefore, locking lever 30 connects coupling bar 52, lock in hinged way Tight plate 20 and bell crank 40.Bell crank 40 can have about triangular shaped, and its middle (center) bearing 13 and joint 31 were positioned at should On two angles of triangle.The above-mentioned bolt 41 for promptly discharging is arranged in remaining angle, driving plate 64 can be passed through Interior groove 66 drives bolt 41.

For example, as shown in Fig. 3 and 4 embodiment, coupling bar 52 and locking lever can directly be produced by ball-joint 35 Being articulated and connected between 30.Due to the joint 35, coupling bar 52 can rotate relative to locking lever 30 in either direction, so as to Enough positions for offsetting be hinged period change.However, for example according to Fig. 2 embodiment, pass through intermediate bar 52' and two joint 33 It is also possible that two direction of rotation, which are implemented separately, with 34.In this case, coupling bar 52 can be relative by the first joint 34 Intermediate bar 52 rotates on horizontal axis, is closed conversely, coupling bar 52 can pass sequentially through second joint 33 with respect to locking lever 30 Rotated in vertical axis.

Fig. 3 shows the locking device 10 in closing position.In this case, the rotational lock plate 20 in bearing 14, Motion of the limitation transverse to the driver element crossbeam in slotted eye 21 so as to clamping screw 65 shown in broken lines.Pass through Fig. 3 reference symbol VR identifies the direction of motion.In addition, locking lever 30 and bell crank 40 are on dead-centre position is crossed.At this In the case of kind, joint 32 that connecting line VV is present between the bearing 13 of bell crank 40 and locking lever 30 and latch 20 it Between.The joint 31 that another connecting line VV is present between the bearing 13 of bell crank 40 and locking lever 30 and bell crank 40 it Between.In crossing in dead-centre position for two levers 30 and 40, this two connecting line includes angle [alpha].

Dead-centre position can be crossed driving coupling bar 52 that lever 30,40 is removed into this in a manner of the motor, so as to The left end of locking lever 30 in the direction pull-up cardon 3 of motor of the coupling bar 52 as shown in Fig. 4 arrows.Therefore, locking lever 30 Pivot in a counterclockwise direction, but the pivotal movement of the locking lever is merely able to when bell crank 40 and locking Plate 20 rotates in their respective bearing 13,14 simultaneously when.In order to reach this target, bell crank 40 is on bearing 13 rotate in a clockwise direction, and wherein this is also applied to rotation of the latch 20 in bearing 14.By this way, two connecting line VV and VU are temporarily positioned in top of each other, until they are moved apart from each other again, so as to overcome dead-centre position.In reversed closed mistake During the motion of journey and coupling bar 52 away from the motor, two connecting line VV and VU are temporarily positioned in top of each other, until they are arrived Dead-centre position is crossed up to shown in Fig. 3.

During opening procedure, latch 20 rotates on bearing 14 simultaneously, is transversely to the positioning elliptical of crossbeam 67 Locking hole 21, it is, can be transverse to door described in the cross beam movement, because the clamping screw now can be in ellipse Moved in hole 21.If use the locking slot rather than slotted eye that outwardly open, then also can be by the clamping screw It is fully removed the locking slot.In the case of shown in Fig. 4, motion of the locking device 10 on the VR of direction is in the door Opening procedure during occur, so that no longer pointed clamping screw 65 is positioned in the region of bottom plate 11, but laterally In this skew.Therefore, support rails 53 are interior together with locking device 10 in orbit of guide rail 62 in the lateral direction of vehicle It is mobile.

Also, in order in case of emergency not open the door hingedly in a manner of coupling bar 52 and the motor, Also bell crank 40 can be used to promptly discharge.In order to reach this target, for example, bolt 41 is arranged in into bell crank 40 Region in, and can be by manually moving the urgent bolt 41 on the rotary bell crank in a clockwise direction of bearing 13 40.Especially, can be realized by way of being connected at least one Bowden cables of artificial triggering accident brake described Manual drive.It can also discharge by this way and cross dead-centre position between bell crank 40 and locking lever 30.In its driving When, urgent bolt 41 moves (see Fig. 1) in groove 66, so as to which driving of the bolt 41 above driving plate 64 can occur.

Fig. 3 and 4 be also shown for bottom plate 11 have be characterized as the groove 12 in the region of latch 20.In the groove 12 The thickness of region bottom plate 11 is reduced to such degree：The adjutage 22 of latch 20 can be during its rotation in groove Moved in 12.In this case, towards bottom plate 11 adjutage 22 downside be located at than latch 20 remaining downside more Close to the position of bottom plate 11.In addition, Fig. 4 shows the groove 12 realized in a manner of curved shape in bottom plate 11, especially in axle Hold in 14 region, so that the whole material thickness of bottom plate 11 can be used for the configuration of the upper bearing (metal) 14 of bottom plate 11.

By this way, the respective shapes of groove 12 to realize block 12', in its surface latch 20 Adjutage 22 is only leaned in maximum open position.However, it is also possible to configure different types of block, locked in unlocked position The other assemblies of tight plate 20 or retaining mechanism are against which.

In addition adjutage 22 can be connected to by latch by connecting rod 23, it is equally rotatably installed in support rails 53 other end, so as to pass through motor 50 and the latch of 52 synchronous rotary of coupling bar two.In this case, equally can be with The locking element of such as bolt is arranged in the driving plate 64 in the second latch region, so as to which the door locking is existed On the both sides of support rails 53.

In order to prevent the extra rotation of locking lever 30 in dead-centre position is crossed in a clockwise direction, that is, crossing dead point Rotated outside position, bottom plate 11 can be configured with block, locking lever 30 on position is defined against which.For example, this In the case of can realize locking lever 30, so as to which it is most greater than abutting bearing 13 on dead-centre position.In embodiments of the invention In, by modeling for the purpose in the region between the interface 35 of coupling bar 52 and the joint 31 together with bell crank 40 Material block is arranged in locking lever 30, wherein it is preferred to, the plastic block has abuts the gear in the form of bearing 13 The concave outer profile of block circumference.

In addition capturing element 15 can be formed on bottom plate 11, wherein being connected to the lock of coupling bar 52 (or intermediate bar 52') The end of tight lever 30 contacts at it when being moved on the region with the capturing element.In order to reach this target, such as can So that corrugated metal sheet 15 is arranged on bottom plate 11.Corrugated metal sheet 15 reaches such degree from bottom plate 11：Its point Not with coupling bar 52 or the ends contact of locking lever 30, coupled thereon when these components are moving on metallic plate 15.For example, Locking lever 30 can have the spherical or circular bolt being characterized as with the high degree in contact with corrugated metal sheet 15 on the downside of it Mode contact point.By this way, when the contact point of locking lever 30 is it is determined that be engaged on corrugated metal sheet on position Locking lever 30 can be locked at when between 15 both heights on bottom plate 11.Preferably, the spring of corrugated metal sheet 15 is pacified On bottom plate 11, so as to which when it contacts locking lever 30, it is surrendered, when the contact point of locking lever 30 is engaged in depression When it rebounds again.Be then able to overcome spring force to remove locking lever 30 from the depression, wherein locking lever 30 in Corrugated metal sheet 15 is surrendered again while slip on adjacent height.Sum it up, such a capturing element 15 can be used Make to overcome the extra coverage for carelessly discharging dead-centre position under the locking state of locking device.
