End, door machine beam 1 is passed through longitudinal linear bearing assembly and is connected with car body, and can carry out longitudinal cunning in the horizontal plane along longitudinal guide shaft
Dynamic.Because door machine beam 1 entirety can be with longitudinal sliding motion, therefore train door can complete longitudinal sliding motion with door machine beam 1, thus realizing train
Door freely activity in a range of horizontal plane.
As shown in Fig. 2 being provided with two train door guide rails 7 in car body, this two train door guide rails 7 are located at two trains respectively
Between door connecting plate 2 and door machine beam 1, flat with door machine beam 1 away from the end in door machine beam 1 centre position on two train door guide rails 7
OK, on two train door guide rails 7, the end symmetric bending near door machine beam 1 centre position tilts, and train door guide rail 7 can be to close
The direction bending of door machine beam 1 tilts or tilts to the direction bending away from door machine beam 1, this can according to stopping sliding door be train door by
Fill at car door mouth outside car or in-car is filled in and determined at car door mouth.It has been respectively articulated with directive wheel 8 on two train door connecting plates 2,
Directive wheel 8 is stretched into and is located in the relative train door guide rail 7 in train door connecting plate 2 position with it, and directive wheel 8 is in train door guide rail 7
Interior slip, train door enters line slip completely along the restriction range of train door guide rail 7, and pull-type the beating of plug realizing train door opens or closes
Close.
As shown in figure 1, two train door connecting plates 2 are positioned at the side of door machine beam 1, the opposite side centre position of door machine beam 1
It is provided with locking mechanism.As shown in FIG. 3 to 7, locking mechanism includes：Two latch hooks 9, the locking forks in the middle of two latch hooks 9
10th, it is located at two lock pins 11 of two latch hook 9 both sides respectively, pull the sliding electromagnet 12 of locking fork 10 rotation, be enclosed within and push away
Draw the back-moving spring 13 on electromagnet 12.Two latch hooks 9 and locking fork 10 are installed on a bearing 14, and this bearing 14 is fixing
On door machine beam 1, the middle part of latch hook 9 is hinged on the side of bearing 14, and the bottom centre of locking fork 10 is also articulated to bearing
On 14 side, the bottom two ends of locking fork 10 are provided with two dead bolts 15, and this two dead bolts 15 are convex towards two latch hooks 9 respectively
Go out.On latch hook 9, the end face near locking fork 10 is arc surface 16, and on latch hook 9, the other end near lock pin 11 is provided with
Lockhole 17, the bottom two ends of latch hook fork 10 are provided with two cancave cambered surfaces 18 with the cooperation of arc surface 16 radian, the arc surface of latch hook
16 fit when lock pin 11 does not slip in lockhole 17 is connected on cancave cambered surface 18, and now the opening of lockhole 17 inclines towards lock pin 11
Tiltedly, slip in order to lock pin 11 motion, during latch hook 9 rotation, arc surface 16 is close to during cancave cambered surface 18 rotates it is ensured that rotating
Locking fork 10 will not swing.It is additionally provided with one-level re-entrant angle 19, this one-level re-entrant angle 19 can be with latch hook on the arc surface 16 of latch hook 9
9 rotation and dead bolt 15 clamping.One end of sliding electromagnet 12 be provided with can electrically controlled telescoping push-pull shaft 20, push-pull shaft 20 lead to
The top crossing a connecting rod with locking fork 10 is articulated and connected, and the stretching motion of push-pull shaft 20 can control the rotation shape of latch hook fork 10
State, the rotation status of two latch hooks 9 of locking, with realizing two latch hooks 9, two lock pins 11 are locked or unlocking motion.
Preferably, as shown in Fig. 5,7, the side of latch hook 9 is additionally provided with the spacing recess of connection one-level re-entrant angle 19, on bearing 14
It is provided with two shift finger 21 being located in the spacing recess of two latch hooks 9 respectively, when lock pin 11 slides in or out lockhole 17, lock
Hook 9 is located exactly at the two ends in spacing recess by promotion rotation to extreme position, now shift finger 21.Shift finger 21 can play limit
The effect of lockmaking hook 9 slewing area, makes the locking of train door or unlocks more stable reliability.In order that latch hook 9 keeps after rotation
Correct position, latch hook 9 is provided with moving magnet 22, and the side of bearing 14 is provided with two and is repelled each other with moving magnet 22 peer
Fixed magnet 23, this two fixed magnets 23 are located on the rotational trajectory of two moving magnets 22 respectively, and moving magnet 22 can be with
Latch hook 9 rotate to corresponding fixed magnet 23 aligned in position.One depth is additionally provided with the arc surface 16 of latch hook 9 and is less than one-level
Two grades of re-entrant angles 24 of re-entrant angle 19, promote latch hook 9 to rotate, dead bolt 15 is sliding after two grades of re-entrant angles 24 when lock pin 11 slips in lockhole 17
Enter in one-level re-entrant angle 19, the purpose of design of two re-entrant angles is to make locking fork 10 have two states when locking, and can achieve secondary
By secondary locking, locking, when special circumstances and leading to locking failure, still can ensure that train door cannot be opened it is ensured that passenger
Safety.When dead bolt 15 slips into one-level re-entrant angle 19 or two grades of re-entrant angles 24, two dead bolt 15 Impact direction of locking fork 10 all exist
On same straight line, and this straight line, through the pivot of locking fork 10, does not produce moment of torsion during locking, largely avoids shaking
The dynamic danger leading to break off relations.
More excellent, as shown in Fig. 3,6, lock pin 11 is arranged on a belt clamp 25, is fixed on slide block peace by belt clamp 25
On dress seat 3, slide block mounting seat 3 is connected on Timing Belt 4 by belt clamp 25, and two slide block mounting seats 3 are connected to synchronization
On not homonymy with 4, carry out move toward one another or opposite motion in order to synchronous.Belt clamp 25 is provided with the bar shaped of horizontally set
Hole, the end of lock pin 11 is locked at this bar shaped in the hole by nut and pad, and lock pin 11 can adjust lateral attitude along bar hole, with
The plug amount of drawing after controlling train door to close and the tightness of train door closing.
The automatic blocking process of locking mechanism is as follows, as shown in fig. 6, when train door is not turned off, sliding electromagnet 12 is in
Off-position, due to two latch hooks 9 in unlocking condition respectively the bottom two ends with locking fork 10 abut, shift finger 21 limits
The rotation in latch hook 9 one direction, fixed magnet 23 limits the rotation of latch hook 9 other direction, and now locking fork 10 is in stable inclination
State, push-pull shaft 20 position of sliding electromagnet with energising adhesive when position identical, back-moving spring 13 is compressed, Timing Belt
During transmission component band movable slider mounting seat 3 move toward one another, train door progressively closes off, and two lock pins 11 are to central motion extremely
Slip in the lockhole 17 of two latch hooks, two lock pins 11 are further continued for central motion, promote two latch hooks 9 to rotate, when locking pendulum
When two dead bolts 15 on bar 10 cross one-level re-entrant angle 19, locking fork 10 reset of card under the screen resilience effect of back-moving spring 13
Live one-level re-entrant angle 19, latch hook 9 is blocked and cannot reversely rotate by dead bolt 15, as shown in figure 3, now the opening of lockhole 17 turns to court
On, lock pin 11 cannot deviate from lockhole 17, thus realizing the locking of train door by transverse shifting.
The automatic unlocking process of locking mechanism is as follows, as shown in figure 3, when train door needs to open, sliding electromagnet
Push-pull shaft 20 energising is shunk, and pulls locking fork 10 to rotate, back-moving spring 13 is compressed, now the dead bolt 17 of locking fork 10 takes off
From one-level re-entrant angle 19 and two grades of re-entrant angles 24, the constraint to latch hook 9 for the release, toothed belt transmission assembly band movable slider mounting seat 3 is carried out
