Field of the present invention
Present invention relates in general to the door furniture device system, these systems belong to and are commonly used to two on the passenger carrying vehicle box-like (Bi-parting) car door is carried out operation types.More specifically, the invention belongs to a kind of Central locking mechanism, it can be locked at the state of pushing back or the non-state that pushes back with two fan door-plates.
Background of the present invention
Background information hereinafter is used to help the reader that the common applied environment of the present invention is understood.Unless special instruction is arranged in this article in addition, otherwise the word that this paper adopted will be not limited to concrete narrow sense and understand.
What the crowd was known is: in the passenger carrying vehicle field, usually adopted an automatic door operator, it has a cover locking mechanism, and so that the door-plate that is connected on this automatic door operator is carried out locking, door-plate also is subjected to the driving of this operator and closed and open a aperture of door on the passenger car.Among these door operatorss, the sort of gate device system that relevant with the invention disclosed herein content is discloses in the literal of United States Patent (USP) 6032416 and accompanying drawing.Fig. 1 has represented a door opening on the railcar sidewall.Be close to the upper edge of this aperture of door, flatly be provided with a substrate along its length direction, it is fixed on the car body of door opening top, perhaps is attached on the car body and becomes an one parts.Said gate device system just is connected on this compartment by this substrate.
For the locking characteristic of gate device of the prior art system, each outdoors suspension bracket all have the contact support (not shown) of the section of being connected thereto.Above suspension bracket outdoors, designed a contact support (not shown), being used for that same first door lock assembly cooperates with is that the Yishanmen plate forms a lock.Similarly, one second door lock assembly be positioned at another outdoors of suspension bracket top contact the cooperation of support (not shown) and be that second door-plate forms a lock.First, second door lock assembly still is the device of a pair of mirror image symmetry.
Owing to this reason, so succinct on describing is described in detail each parts to second door lock assembly not.Can also be with reference to each accompanying drawing in the United States Patent (USP) 6032416.Shown in Fig. 4 A-C, first door lock assembly comprise a latch fitting, pivotal pin, actuator of unblanking, one push back that part, latch bar, one are urgent to be discharged rotor, complete atresia switch and one and push back latch switch.
To shown in Fig. 5 C, second door lock assembly comprises a latch fitting and the actuator of unblanking as Fig. 5 A.Also expressed among the figure and pushed back part, latch bar, promptly discharged rotor, complete atresia switch and push back latch switch, but identified with number designation in the drawings for simplicity and not.Complete atresia switch and push back latch switch and be provided with as the status switch of door, their first contact provides input signal to a door controller (not shown).
Return again referring to the expression first door lock assembly Fig. 4 A to 4C, certain the some place above the right part of latch fitting, the upper end of latch bar is pivotally attached on the body of this assembly.Latch bar has a cam (dotting among the figure) on the other end at its pivotal pin place.Lower end in this latch bar is lock bolt self.The complete atresia switch is positioned at the rear that pushes back latch switch, and these two switches all are fixed on the body of lock set.Push back part and be pivotably connected on the body, and the pivoting point next-door neighbour pushes back the right side of latch switch.The unblank right-hand member of actuator is fixed on the body of assembly.The left end of this actuator extends a push rod.The high order end of this push rod is connected to the top of latch fitting left end by a pin, and is arranged in the ditch trough connection that pushes back part.
Latch fitting can be around the rotation of a trunnion, and it has following feature: the locking step, push back step, a cam dump tank and formed parts on its high order end: a lockup arm.The position of said cam dump tank close its right-hand member on the latch fitting top side, and push back step close position in the middle on the latch fitting bottom side.Said locking step is just built in the bottom of latch fitting right-hand member.
Arrangement form in each comfortable first, second door lock assembly of said two latch fittings makes them be biased under normal conditions on the downward state.For first door lock assembly, Fig. 4 C has the most clearly expression.Fig. 5 C then has best expression to second door lock assembly.Specifically, begin until Fig. 4 A, represented to be subjected to the promotion of motor and driving mechanism and to move right when the fastening position, be positioned at the following processes that the contact support of suspension bracket top outdoors slided, finally was positioned at the latch fitting bottom side from left to right along with first from Fig. 2.
Along with suspension bracket outdoors and coupled door continue to the right, the protuberantia that contacts support has just been run into the left part of lock bolt lower end, thereby makes this lock bolt counterclockwise rotate.This anticlockwise rotation causes the cam on this lock bolt to leave the position that engages with cam receiving slit on the latch fitting.Because its right-hand member and cam are thrown off, so latch fitting just can rotate around a trunnion clockwise direction subsequently, thereby its right-hand member just falls to being pressed on the top of support.Shown in Fig. 4 B, along with suspension bracket outdoors and connect car door and arrive near the position of said fastening position in the 40mm scope because latch fitting is a biased downward, so the turning of the leftmost side is at first pushed back step by one and blocks on the support.This just makes that pushing back part clockwise rotates, and closes with the bottom connection that pushes back locking switch.Two contacts at this switch all are under the condition of closing, this switch cuts out that part that belongs to self in the DCLC train line, and send one to DCU (recording controller) and push back locking signal, to show that pushing back lock has engaged (that is to say that element has been in and has pushed back lock-out state).Shown in Fig. 4 C, along with motor and driving mechanism continue to carry out the operation of closing the door, the turning of the contact support leftmost side has just moved through the district that pushes back between two steps, and is finally blocked by the locking step.This just makes latch fitting clockwise rotate further around said trunnion, thereby its extended left arm just closes with the bottom connection of complete lock-up cock.Be under the situation of closing at its contact, this complete lock-up cock sends a complete locking signal to a DCU, shows to be bonded into complete locking under the present case.By this way, latch fitting just has been in complete locking states, in this state, the turning butt of the contact support leftmost side the locking step, has prevented that thus suspension bracket outdoors and first of being connected thereof from opening again.
Owing to have the annexation of driving mechanism, so when first moved right, second also to left movement.Specifically, again referring to from Fig. 2 to the process shown in Fig. 5 A, be moved to the left to its fastening position along with second, be positioned at one outdoors the contact support of suspension bracket top slide from right to left, finally be positioned at a latch fitting bottom side below.Along with suspension bracket outdoors and and second of being connected continue to be moved to the left, the protuberantia on the support has just been run into the right side part of lock bolt lower end in the assembly, thereby makes the rotation of lock bolt clockwise direction.This clockwise rotation makes the cam on the lock bolt leave the position that engages with cam receiving slit on the latch fitting.Because its left end and cam are thrown off, so latch fitting just can rotate counterclockwise around a trunnion subsequently, thereby its left end is just fallen on the top of support.
Shown in Fig. 5 B, along with suspension bracket outdoors and the door that connected thereof near said fastening position in the 40mm scope, because latch fitting is had the effect of biased downward, so the turning of the rightmost side will be blocked by the step that pushes back on the latch fitting at first on the contact support.This just makes the part that pushes back of assembly rotate counterclockwise, and closes with the corresponding bottom connection that pushes back locking switch.Two contacts at this switch all are under the condition of closing, this switch cuts out one's own that part in the DCLC train line, and send one to DCU (recording controller) and push back locking signal, engaged (that is to say that element has been in and has pushed back lock-out state) with the lock that pushes back that shows latch fitting.
Shown in Fig. 5 C, along with motor and driving mechanism continue to carry out the operation of closing the door, the turning of the contact support rightmost side has just moved through on the latch fitting district that pushes back between two steps, and is finally blocked by the locking step.This just makes latch fitting rotate counterclockwise further around its trunnion, thereby its extended to the right arm just closes with the bottom connection of the complete lock-up cock of assembly.Be under the situation of closing at its contact, this complete lock-up cock sends a complete locking signal to a DCU, shows that this latch fitting has been bonded into complete locking under the present case.By this way, latch fitting just has been in complete locking states, and in this state, its locking step is as an abutting part, and butt the turning of the contact support rightmost side, has prevented that thus second door frame from opening again.In addition, because the annexation of driving mechanism, as long as there is any one latch fitting to be in complete locking, two fan door-plates just all can not be opened.
As gate device system common in the prior art, above-mentioned door operators has independently two cover door lock assemblies.As shown in Figure 2, this two covers door lock assembly has each other parts, and above the gateway, the point out of the ordinary place of opposite sides thereof is connected on the substrate.But recent practical application shows: adopt two single upright door lock assemblies to have some disadvantages.
Mention indirectly as mentioned like that, two fan door-plates come down to be mechanically connected to together mutually by driving mechanism and relevant parts.Thereby when two fan door-plates were shifted to open position and complete locked position, two cover door lock assemblies will as one man move in fact.This just needs the setting accuracy of two door lock assemblies on substrate will make them can be in identical state to companion's (being another fan door-plate) with it at synchronization.For example, when two door-plates closed up, two door lock assemblies should almost side by side be in and push back lock-out state and then be in complete locking states.If one of them not in place or the two less than the position, then can imagine: certain door lock assembly can still keep unblanking, simultaneously another assembly then is in correct complete locking states.
In addition, these door lock assemblies comprise some complex component, and these parts are to need to adjust, and change rotatablely moving of latch fitting into the rectilinear motion with actuator, thereby come opposite house to carry out locking and unblank.
From above description as can be seen, thus these door lock assemblies adjust comparatively continually with regard to needs, be consistent with the action that guarantees them.Thereby a kind of like this locking mechanism of needs design: its design can overcome defective of the prior art, and an adjustment workload that needs are few and the parts that comprised are considerably less.

On the door enable possition, at gravity and reversing under the effect of bias spring element 206, latch fitting 202 is biased in as under the normality on the states that its pivot 218 is located downwards.In the door closing course, the special-shaped front end 223 that is provided with on slope 209 on stay hook backstop 208 and the latch fitting 202 engages, thereby produce an active force, stay hook backstop 208 wherein is installed on the suspension bracket 312, said active force acts on the latch fitting, it is rotated in the counterclockwise direction, thus subsequently by the engaging of movable hook backstop 207 and the recessed rank 222 of latch fitting, make latch fitting to clear up to the activity backstop 207 that also is installed on the suspension bracket 312.Common situation is: existing systems will have one or more other parts, comes to adjust the rotational positioning and the timing of latch fitting similar structures in closure-beginning cyclic process, with the engagement relationship of realizing that the similar locking face of above-mentioned usefulness or mechanism's entity are realized.
In current preferred embodiment, the parts of each mirror image symmetry comprise second a door lock spare 202 as shown in Fig. 6 and Fig. 7 in the Central locking mechanism 200, and it is used for being fixed on make position with second 110.What together be provided with the second door lock spare 202 is one second actuator 201 of unblanking, and it is connected to the control system (not shown) by a line (not shown).Also be provided with the second back-up block assembly 212, second complete locking sensor and one second and push back sensor 204.The second door lock spare 202 preferably is biased to the second door lock stop bit shown in Figure 10 and puts, and on this position, second latch fitting is pressed on the movable hook backstop 207 of door 110 suspension brackets 121, prevents second unlatching thus.The second door lock spare 202 also can be driven and moved to second lockset position of coupler shown in Figure 11 by second actuator 201 of unblanking, and on this position, latch fitting makes second 110 to become openable.
Preferably: have at least part door bias force to act on the second door lock spare 202, thereby on the second door lock spare 202, produce one second door lock spare load.This second door lock spare load has prevented that the second door lock spare 202 from putting from the second door lock stop bit and has moved to second lockset position of coupler when motor 301 is not switched on, like this, to second unblank except carrying second unlocking signal to second actuator 201 of unblanking, also to send one and close gate signal to motor 301, overcome at least a portion door bias force to produce second closing force, thus, second actuator 201 of unblanking the second door lock spare 202 can be put from the second door lock stop bit move to second lockset position of coupler before, earlier unloading at least a portion acts on the second door lock spare load on second lock piece 202.Thereby the first door lock spare and the second door lock spare have redundant measure to first 20 and second 110 locking.
In current preferred embodiment, the second door lock spare 202 has second latch fitting of representing and pushes back position 222 in Fig. 9, like this, if certain passenger's body part, coat or other article are clamped by second 110, the passenger just can open the door second and shift a door onto with second 110 on the direction 116 and push back the position, thereby pull out body part, coat or article, door wherein pushes back the position and realizes by the second door lock spare 202.Be in second when pushing back the position when second, the closure of crack between a door and its frame 12 is enough high, makes the passenger not get out from crack between a door and its frame 12.
Second emergency unchaining mechanism similar with emergency unchaining mechanism 205 should be set, be used in case of emergency discharging second latch fitting 202.This second emergency unchaining rotor should be touched simultaneously with first emergency unchaining mechanism 205.For example, each emergency unchaining mechanism all can have a flexible tractive element 72, and two tractive elements are all started by the same handle.
110 move in the process of make position at door 20 or door, push back the district in case door 20 or 110 arrives, latch fitting 202 just falls into first and pushes back lock class, and the offset that pushes back wherein is about 57.5 millimeters from basic closed fully position.At this moment, push back limit switch 204 and be activated this state of confirming among Fig. 9.
Along with door 20 or 110 continue to be carried out closed and when arriving almost completely closed position, because the first locking level part 222 engages with a movable hook backstop, so no matter be or use power drive, door 20 or 110 apertures that reopen are surpassed push back the district with manpower.
In case arrive on the closed fully basically position, a seal 46 just is pressed on the door limit weather strip 120 of pairing.Latch fitting 202 just drops in the second locking level, and the second locking level has a second level lock portion 216, and as shown in figure 10, it engages with a movable hook backstop 207.The complete locking limit switch 203 of door is touched and is confirmed this state.In case second level locking is engaged to, just stop to the door motor transmitting power, but owing to there is the effect of latch fitting 202, the compressing of part gate seal is still existence in the effect.
In the incipient stage of door opening travel, the enabling signal of exporting from the door controller (not shown) at first makes door 20 and door 110 compress mutually on closing direction, to push gate seal 46 and 120 further.This closes a motion and unloads fully except acting on the preload on the latch fitting 202, and this preload is owing to the movable hook backstop 207 that is installed on the linear bearing case leading edge occurs.In case this preload is laid down, just as shown in Figure 11, latch fitting 202 is thrown off in solenoid 201 energisings to unblanking.When the aperture of door or 110 surpasses when pushing back the district, just cut off the power of carrying to the solenoid 201 of unblanking, and latch fitting 202 is fallen under action of gravity.
This Central locking mechanism has several characteristic.It is designed in when the two pass door is opened, by same set of lock assembly two fully independently door lock carry out work.Thereby, under situation about breaking down, can mask the door 20 or 110 that is subjected to fault effects, and the door 110 or 20 of maintenance pairing is working properly.Like this, the passenger still can pass in and out aperture of door 12, and just traffic volume reduces.
On the fully closed position of door, locking mechanism 200 is keeping the mechanical presses relation between the weather strip 46,120 on the edge in front of the door.This has three purposes.At first be to prevent measure as a danger, this can prevent fastener 202 lock in person even if, and only the door controller (not shown) is carried out further roof pressure to gate seal earlier.This just means: even feasible solenoid 201 energisings of unblanking of certain fault, it can not open door 20 or 110, unless door controller has at first been carried out the higher extruding of degree to gate seal 46 and 120; The second, this has reduced the maximum noise value in the passenger carrying vehicle 16 and the vibration of car door in the driving process.
Door lock assembly in the Central locking mechanism 200 can carry out work according to the form of two-stage lock, that is to say: have the locking of pushing back and complete two states of locking.The unique shape of latch fitting 202 makes that door can be by mechanical locking in two each other zones: (1) door pushes back the district; And the complete make position of (2) door, latch fitting 202 wherein has one and pushes back step 222 and a locking step 216.
Push back when district when door 20 and 110 is locked in, their aperture all can not be greater than 57.5 millimeters, even occur under the situation of power failure or circuit problem in door operators 290 or door controller (not shown) also be like this.Thereby, being locked under the condition that pushes back the district at door 20 and 110, passenger carrying vehicle also can leave the station safely.Passenger carrying vehicle is locked in to push back under district's condition at door 20,110 to be had aspect two with regard to the advantage of leaving the station.At first, when passenger carrying vehicle left platform, if the passenger is sandwiched between the door-plate, then the passenger can break away from clamping by each fan door-plate being opened nearly 57.5 mm distance.This athletic meeting of door is detected, and reports to the driver/monitoring system (not shown) of passenger carrying vehicle.If do not have this feature, if then door is locked in complete make position, the passenger will be clipped between the door-plate all the time, conceivable to: even the phenomenon of being drawn away by train can appear.Secondly, said to push back the district enough big, makes the passenger can oneself free (or own wallet, article bag pull are come out), but this pushes back the district and does not attend the meeting greatly again and make the passenger drop out degree outside the car door.
Than existing door lock assembly, two adjustment of 200 needs of Central locking mechanism.First adjustment is that opposite house 20 or door 110 carry out, and specifically is opposite house 20 and 110 neutrality is adjusted, and this adjustment is because the scale error limit of each parts of door 20 and 110, gate seal 46,120 and upper top door mechanism 290 causes.Can move to a setting position and carry out such adjustment simply by loosening fasteners 210 and with active supporting piece 207.
Second adjustment is that the startup in order to ensure sensor 203 and 204 is in good time and appropriate, and wherein sensor 203 and 204 can be adjusted simultaneously.
Than common door lock set existing, that adopt the electronic or pneumatic actuator of linear pattern, the components number of Central locking mechanism 200 seldom.This locking mechanism specially is designed to comprise the least possible parts.For reaching this point, each part must painstakingly be designed to have a plurality of functions.For example, back-up block assembly 212 just has many purposes.Each assembly 212 is all supporting the Yishanmen plate by straight line pole axle 213, also is provided with rotating fulcrum for one of them locking hook 202 simultaneously.This back-up block assembly 212 is also as the mounting seat of solenoid 201 and switch 203,204.This assembly is also supporting energency-unlocking bar 205, and is supporting the wire harness of each electric component in the Central locking mechanism 200.This assembly is the backstop of conduct door-plate when driving mechanism lost efficacy also.Each back-up block assembly 212 is also supporting a cam that pushes back limit switch 204 that is used for touching each door lock assembly.In addition, a rotary solenoid 201 is connected with latch fitting 202 by cam 211.
Central locking mechanism 200 also is designed to tamper-evident.Since locking mechanism 200 be arranged in gateway 12 directly over, so when door 20 and 110 was unlimited fully, the passenger can be corrupted to lock assembly.In order to reduce the possibility that the passenger monkeys, this locking mechanism 200 is configured to have following feature.At first, shield the middle body of locking mechanism 200 with a housing 214 with limited hole, it can prevent that not only foreign material from accumulating in mechanism 200 inside, and can prevent touching mechanism 200.Secondly, those can not carry out on the section of structural defence with a housing in mechanism 200, and those exposed parts will be by having the material manufacturing of setting intensity, to resist the destruction of playing with of unrelated person.The 3rd, the stay hook backstop 208 of each lock assembly have one domatic 209, when door was closed, this is domatic to lift corresponding latch fitting 202.When door was open mode, locking hook 202 exposed, and when door 20,110 was opened, locking hook 202 kept being biased downward normality.Along with the closure of door, domatic 209 on each backstop 208 is just lifted corresponding latch fitting 202, and this latch fitting can engage automatically subsequently.In addition, even someone has touched latch fitting 202 (for example: it is lifted or depresses), the operation of door can not be affected yet.
Although above currently preferred embodiment of the present invention and various other alternative have been made detailed description according to the regulation of Patent Law; but can recognize: the those of skill in the art in the association area can make the remodeling and the adaptability revision of multiple other form under the prerequisite departing from design philosophy of the present invention and claims protection domain not.
