Operation principle of the present utility model and the course of work are as follows:

First, car is in flat bed or onlocking zone

1), door machine normal door: motor action makes Timing Belt move to enabling direction, by beating during Timing Belt horizontal movement Bar 7 drives startup block 6 to rotate, and makes left-hand door tool arm 2 and right door tool arm 3 produce the dynamic of gathering now by the transmission starting bearing pin 5 Making, during drawing in, right door tool arm 3 first touches hall door and unlocks croquet 27, and hall door lock unlocks.When start block 6 turn to against During the first locating part 24, start hook 15 and rotate under the effect starting hook extension spring 16, start hook 15 upper groove 15.1b and fall and block Live and make bar 7, now start block 6 phase opposite house cutter base plate 1 position motionless.In above-mentioned course of action, left-hand door tool arm 2 and right door tool arm 3 continue to draw in and touch the main croquet of hall door 26, and the barrier force of the main croquet of hall door 26 passes to start bearing pin 5, thus drives and open Rubber ring 19 on untie-sell axle 5, by moving to upper side edge position from the lower side position of actuating hole 6.1, starts bearing pin 5 and leads to simultaneously Crossing the kidney-shaped notch 8.1 coordinating with it to order about unlocking plectrum 8 and turn round, the center of circle of the arc surface 8.2 on unlocking plectrum 8 occurs partially Moving, arc surface 8.2 produces pressing action, and pushing down unblock bearing 11 makes latch hook 10 lift, it is achieved normal door unlocks (such as Fig. 3 institute Show).

2), door machine is normally closed the door: driven by motor synchronization is taken to close the door direction motion, close the door will put in place when, start hook On the right of in the of 15, the end of extension rod 15.2 strikes the fixing bolt that a machine center is arranged, and starts the arresting lever on hook 15 left side 15.1 are rotated up lifting, and groove 15.1b disengages with making bar 7, and starting block 6 can rotate to direction of closing the door in the effect of Timing Belt； Start and make left-hand door tool arm 2 and right door tool arm 3 open and progressively disengage the main door of hall door by starting the transmission of bearing pin 5 when block 6 rotates Ball 26, under the effect of compression spring 23, starts bearing pin 5 and is returned to the lower side position of actuating hole 6.1；Now unlocking plectrum 8 revolutions, the center of circle of the arc surface 8.2 on unlocking plectrum 8 returns to start the pivot of block 6, and latch hook 10 is in latch hook extension spring 18 Effect is lower to be resetted and again hooks hook plate 12, it is achieved locking；Contact 13 on latch hook 10 and thimble switch 14 connection simultaneously.Left-hand door Tool arm 2 and right door tool arm 3 continue to open, and right door tool arm 3 departs from hall door and unlocks croquet 27, and hall door is locked and connects safety return circuit, Start block 6 and start the effect of block extension spring 17 against the first locating part 24, door machine door-closing in-place.

3), taking off door in any case in sedan-chair: no matter whether motor is charged, it is all consistent for taking off an action producing in sedan-chair , i.e. door machine link plate drives door cutter base plate 1 to the action of enabling direction, and owing to Timing Belt is failure to actuate, starting block 6 will not be to enabling side To rotation, left-hand door tool arm 2 and right door tool arm 3 will not produce the action of gathering.Certain owing to leaving between latch hook 10 and hook plate 12 Gap, when door machine link plate continuation action to right door tool arm 3 touch hall door unlock croquet 27 when, first by hall door unlock, then Touching the main croquet of hall door 26, the barrier force of the main croquet of hall door 26 passes to start bearing pin 5, and action hereafter is just normally opened with door machine Unlocking motion during door is identical, makes gate unlock, and gate hall door is opened along (as shown in Figure 4).

4), Room outward swinging door in any case: first with triangulation chain key, hall door is unlocked outside the Room, open hall door to enabling direction Action, until left-hand door tool arm 2 encountered by the main croquet of hall door 26, the enabling power of the main croquet of hall door 26 passes to open by left-hand door tool arm 2 Untie-sell axle 5, action hereafter is identical with unlocking motion during door machine normal door, makes gate unlock, and hall door gate is beaten together Open.

2nd, car is in non-onlocking zone

1), motor is charged, enabling misoperation: motor action makes Timing Belt move to enabling direction, Timing Belt horizontal movement When by beat bar 7 drive start block 6 rotate, now by start bearing pin 5 transmission make left-hand door tool arm 2 and right door tool arm 3 produce The action drawn in, during left-hand door tool arm 2 and right door tool arm 3 continue to draw in, owing to car is in non-onlocking zone, contact is not To croquet, therefore starting bearing pin 5 and being failure to actuate, latch hook 10 does not unlocks；Then Timing Belt continues to the motion of enabling direction, thus drives Door lock device mass motion, until latch hook 10 hooks hook plate 12, what now gate was opened is smaller than 50mm, meets GB and wants Ask.

2), take off door in sedan-chair: door machine link plate drives door cutter base plate 1 to the action of enabling direction, owing to Timing Belt is failure to actuate, start Block 6 will not rotate to enabling direction, and left-hand door tool arm 2 and right door tool arm 3 will not produce the action of gathering.Owing to car is in non-opening Lock region, does not reaches croquet, therefore starts bearing pin 5 and is failure to actuate, and latch hook 10 does not unlocks；Door machine link plate continues motion, until lock Hook 10 hooks hook plate 12, and what now gate was opened is smaller than 50mm, meets Standard (as shown in Figure 5).

3), rescue outside the Room: first with triangulation chain key, hall door is unlocked outside the Room, fully open hall door, now it can be seen that door Unblock steel wire rope 20 on plate, pulls dynamic unblock steel wire rope 20, makes solution locking plate 21 turn round, solve locking plate 21 and stir limited block 22 and carry Moveable lock hook 10 unlocks, more manually pushs gate aside, can rescue stranded passenger.When unclamping unblock steel wire rope 20, latch hook 10 is at lock Automatically reseting under the effect of hook extension spring 18, latch hook 10 maintains the lock status.

Teaching preferred embodiment of the present utility model in detail above, those skilled in the art is according to description herein In the case of without departing from principle and advantage of the present utility model, various modification can be produced to specific embodiment or equivalence is replaced Generation, and these changes and improvements broadly fall into protection domain of the present utility model.
